A few years ago when I was still an apple fan boy, friend of mine bragging me about how android is awesome, we were drinking some shots at our local pub and I was starting to get light headed. At one point he showed me so called "terminal emulator" app. I checked it out, and assumed it's an emulation, just like dosbox, so I decided to verify that "rm -rf *"... (the phone was rooted)
The phone shutdown within seconds, I couldn't stop laughing, while my friend was shock that his new phone was longer booting.
Luckily he managed to reflash the ROM. What can I learn from that experience?
1. Don't drink and sudo
2. Don't call your app an emulator if it's the real deal.34 -
Yesterday (or the day before that depending on your timezone and day-night schedule - this Friday) my OnePlus 6T arrived. After only 2 days of time between placing the order and actually getting the phone, quite impressive!
The DHL guy asked me upon receipt - is it the OnePlus 6T? - Yes it is!! - "An amazing device it is!", he said. And honestly.. he couldn't be more right.
I might be a bit biased on this because after all I did just spend €630 on this phone. But it feels so snappy, high quality, the 8GB of RAM is just.. it blows my mind. But I'm sure that the other reviews did this sort of jazz already.
The things that set this phone apart for me though were the following.
When I get a new phone or tablet, usually the first thing I do is rooting it. This one was no different, about an hour after receipt it was successfully rooted and loaded with Magisk. Currently I'm still in the phase of "getting to know the phone", wherein fuckups are usual. This time again being no different - I removed some apps and apparently did something to it that the search engines - both Google and DuckDuckGo - didn't quite like, as both of them would crash upon application launch. Me in full panic mode of course, desperately trying to find the stock ROM (which doesn't seem to be present in its usual form) or a new set of GApps (which didn't resolve the issue). OnePlus does seem to offer its OTA updates in zip archives though. So I downloaded its latest update (same as what was on the device) and applied it.
That's when the nerdgasm happened.
The "update" was simply a matter of going into the settings, tapping this and that and applying the update. No recovery, no unrooting, no nothing. The update just went like that despite the phone being rooted and just having had TWRP flashed to it. I always wanted this sort of thing, which even the Nexus couldn't offer - having the cake and eating it too. Being able to root the device and muck around with it while still being able to update the device timely without too many hurdles. This fucking thing does it!!!
That is to say, after my initial nerdgasm I did find that it bulldozed over my su binary (effectively unrooting the thing), custom emoji I've set (iOS 12 because fuck Google's most recent emoji set) and some other things. But those are easy to install back, much more so than it would've been to download a whole Android release and dirty flash it, as it was on the Nexus.
Other than that, battery life, dash charging (edit: on that topic, it does remain cool like a cucumber despite getting 15-20W of power jammed into it, quite impressive!), snappiness, the usual jazz.. eh, as I said earlier that's the usual reviewer stuff. But this feature of being able to upgrade the phone while it's modified, that's something which seems to be severely underrated by those.
Oh and during kernel builds, I couldn't quite get the source to work - probably due to my lack of experience with builds of Android kernels - but I did find that this phone actually exposes its kernel config through /proc/config.gz as it should. None of my MediaTek devices do this, so that's something that I found really appealing. Always nice to see when a manufacturer exposes this information to give you a stock sort of config that you can be rest assured will work configuration-wise. And it allows you to see what the stock kernel is actually built with, which again is really nice. I quite like this! It really encourages further development.11 -
Long rant ahead.. 5k characters pretty much completely used. So feel free to have another cup of coffee and have a seat 🙂
So.. a while back this flash drive was stolen from me, right. Well it turns out that other than me, the other guy in that incident also got to the police 😃
Now, let me explain the smiley face. At the time of the incident I was completely at fault. I had no real reason to throw a punch at this guy and my only "excuse" would be that I was drunk as fuck - I've never drank so much as I did that day. Needless to say, not a very good excuse and I don't treat it as such.
But that guy and whoever else it was that he was with, that was the guy (or at least part of the group that did) that stole that flash drive from me.
Context: https://devrant.com/rants/2049733 and https://devrant.com/rants/2088970
So that's great! I thought that I'd lost this flash drive and most importantly the data on it forever. But just this Friday evening as I was meeting with my friend to buy some illicit electronics (high voltage, low frequency arc generators if you catch my drift), a policeman came along and told me about that other guy filing a report as well, with apparently much of the blame now lying on his side due to him having punched me right into the hospital.
So I told the cop, well most of the blame is on me really, I shouldn't have started that fight to begin with, and for that matter not have drunk that much, yada yada yada.. anyway he walked away (good grief, as I was having that friend on visit to purchase those electronics at that exact time!) and he said that this case could just be classified then. Maybe just come along next week to the police office to file a proper explanation but maybe even that won't be needed.
So yeah, great. But for me there's more in it of course - that other guy knows more about that flash drive and the data on it that I care about. So I figured, let's go to the police office and arrange an appointment with this guy. And I got thinking about the technicalities for if I see that drive back and want to recover its data.
So I've got 2 phones, 1 rooted but reliant on the other one that's unrooted for a data connection to my home (because Android Q, and no bootable TWRP available for it yet). And theoretically a laptop that I can put Arch on it no problem but its display backlight is cooked. So if I want to bring that one I'd have to rely on a display from them. Good luck getting that done. No option. And then there's a flash drive that I can bake up with a portable Arch install that I can sideload from one of their machines but on that.. even more so - good luck getting that done. So my phones are my only option.
Just to be clear, the technical challenge is to read that flash drive and get as much data off of it as possible. The drive is 32GB large and has about 16GB used. So I'll need at least that much on whatever I decide to store a copy on, assuming unchanged contents (unlikely). My Nexus 6P with a VPN profile to connect to my home network has 32GB of storage. So theoretically I could use dd and pipe it to gzip to compress the zeroes. That'd give me a resulting file that's close to the actual usage on the flash drive in size. But just in case.. my OnePlus 6T has 256GB of storage but it's got no root access.. so I don't have block access to an attached flash drive from it. Worst case I'd have to open a WiFi hotspot to it and get an sshd going for the Nexus to connect to.
And there we have it! A large storage device, no root access, that nonetheless can make use of something else that doesn't have the storage but satisfies the other requirements.
And then we have things like parted to read out the partition table (and if unchanged, cryptsetup to read out LUKS). Now, I don't know if Termux has these and frankly I don't care. What I need for that is a chroot. But I can't just install Arch x86_64 on a flash drive and plug it into my phone. Linux Deploy to the rescue! 😁
It can make chrooted installations of common distributions on arm64, and it comes extremely close to actual Linux. With some Linux magic I could make that able to read the block device from Android and do all the required sorcery with it. Just a USB-C to 3x USB-A hub required (which I have), with the target flash drive and one to store my chroot on, connected to my Nexus. And fixed!
Let's see if I can get that flash drive back!
P.S.: if you're into electronics and worried about getting stuff like this stolen, customize it. I happen to know one particular property of that flash drive that I can use for verification, although it wasn't explicitly customized. But for instance in that flash drive there was a decorative LED. Those are current limited by a resistor. Factory default can be say 200 ohm - replace it with one with a higher value. That way you can without any doubt verify it to be yours. Along with other extra security additions, this is one of the things I'll be adding to my "keychain v2".11 -
Google, why the fuck did you make the Android default USB connection type be "charging," and NOT "MTP"?! And leave no way to EVER set default to MTP!!!
EVERY SINGLE FUCKING TIME I plug my phone into my pc to transfer files, I have to open my notifications shade, scroll to the bottom to the fixed notifications, and change the mode to MTP, at which point the phone has to re-establish its connection to the pc!
This has been an issue from Android M and onwards. Nonetheless, Google still left in the settings app under developer options on rooted devices, the setting to choose which default USB connection mode you want to use. Even though it doesn't stay on what you choose!! It's like they left that there to purposely toy with us and get a good fucking laugh from our needless suffering.
Google, I love so much of what you do and your approaches, but honestly, some of the things you do, like this and for disabling Chrome extensions on Chrome internal pages, makes me want to strangle you and then throw you in a river of molten lava.34 -
Me: *Trying to get the mobile banking app*
App: Nope, you have a rooted device
Me: *disables root access for apps and adb*
App: Nope, you have a rooted device
Me: *Maybe a xposed module would help*
Xposed: Nope, you have android nougat
Me: *Maybe there's some LineageOS marshmallow rom for my phone*
LineageOS: Nope, just android 7.1

Now that the Phone has a custom rom with root, with only a little issue with some split screen nonsense I'm finally ready to use my phone like a normal ph- OH MY GOD WHAT IS THIS? WHERE THE HELL ARE MY BLOBS? WHAT THE FUUCK!?
Good thing that I rooted with Magisk and I could flash the blobs https://forum.xda-developers.com/ap...

I was just removing empty folders from my MOTO X (Devs sometimes get time to kill).
Saw an empty folder "/storage/emulated/0/"
...DELETED...
~Everything has gone from my gallery, music and I felt like sinking~
Sometimes I think, it is good not being an Android Developer...(Unfortunately I'am)
The positive part of the story:
>>fastboot OEM unlock
I rooted my phone and did too many crazy things I could do with a rooted phone.2 -
I rooted my phone and flashed a new Android version and I got to say, I can't be happier. This is best choice I've made since ever.3

Okay then, ex-android user there.
It started with Xperia TX - it was flagship Sony phone back then. It blew my mind when I touched it for the first time. You know, exploring android for the first time in my life was amazing.
It ran just well for about a year. Then it started to fall apart. I need to clarify that I kept it non-rooted, full stock. I'm not into that customization things.
At first, I noticed significant lags. They were everywhere. The longer I used smartphone, the more lags I encountered. I did factory reset, but lags haven't gone anywhere.
Year 2. Front camera stopped working. Battery became unreliable as fuck, going down to 40% and then instantly to zero. What?
Year 3. Camera broke. It refused to start, just giving me "Camera is not available" error.
I tried factory reset again. It helped at first, but month have passed and all that issues came back. And it also became sluggish as fuck.
Got Meizu m3s year ago. The exact same story. Long story short, in one year I got this:
1. Black spots on every picture I take. Much likely a matrix issue.
2. Camera also became slow as fuck, requiring about 10 seconds to even start.
3. Vertical stripes all along the screen. I never dropped my phone, it just appeared once and became brighter and brighter every day I used the phone.
4. Two huge yellow spots on screen. I think it happened because phone's cpu heat up the screen and it broke.
But the most important thing is that fucking lags chased me in every app, they were everywhere. Fucking tiny-ass lags. And they're not going anywhere, they're become more and more significant with time.
Don't say me about oneplus, samsungs and other top android phones. They are conceptually the same, the only different thing is hardware.
That's why I switched. IPhone has its downsides, but it's silky smooth. And my friend's iPhone 4 (not s) feels just as smooth as my brand new se.
I'm not going to jailbreak it. I don't need customizing the hell out of it.
I just needed quick and reliable phone, and SE seems to be exactly what I wanted.
Peace to android folks tho✌️17 -
Apparently my OP1 can also run Android 10 now...
https://forum.xda-developers.com/on...
And I upgraded my OP6 to LineageOS 17.1 a few weeks ago.
So the only reason I now have a Pixel 2 is because I need a non-rooted phone to access work emails... -
So I have flashed and rooted (superSU) lineageOS 14.1 thats running android 7.1.2 on my phone and now I read that this will trip safetynet and won't allow things like netflix, banking apps or pokemon go - I tried to install netflix and it worked, tried pokemon go and after granting GPS via privacy guard it worked too.
But still it seems that if I would now flash Xposed (which I didn't find a good build for 7.1.2 yet anyway) that it would actually then start tripping those protections and that I should go with "systemless root" via magisk.
How does magisk compare to superSU? I loved root some years ago because of xprivacy, adfree etc. which are actually modifying system files as far as I know and I would like to go as "extreme" as denying camera usage to apps, but not making them crash, so just like xprivacy has fake IMEI I would like to show just a black image served to the app, I remember there was an xposed module doing that, but how far can magisk compare there?
And most importantly is there a way to just hide superSU and xposed from all those detections?4 -
After 6 years of android I just rooted my samsung, how could I have missed the glory of root features for so long...2

Story time: Once I sent our android developer a project that he was supposed to compile and install on a test device. On my machine everything worked perfectly but on his machine ADB would keep failing to install the apk. After an hour of scratching our heads we figured out what happened:
He had just received a new Chinese action camera from Amazon and plugged it into his PC to charge. Turns out it's running rooted Android and runs ADB Debug mode by default. So the build script would try to deploy our phone app to his action cam instead of our test device5 -
What are the different ways by which an Android can play an audio?
I was recently doing a research on Android audio. And i wanted to know which libraries are responsible for audio/video play.
As far as i know media player and exo player are the two libraries which can be used to play user variety of audio/video files, application's raw/asset files and online stream files. Are there any other sounds beside system sounds which i forgot or other libraries which are also used for media playing?
And also what about these system files? Can we access system ringtones and notifications/ alarm tunes in a normal, non-rooted phone? I remember that my previous phone's music player (android kitkat maybe) was able to pick some system ringtones. Is it still possible now(android lollipop nd above) ?
Although i guess music in Android assets or raw files of some other app won't be accessable to my app, unless i am having screen record permissions? -

Are native Android apps easier to write now than like back in KitKat days?
I need a app that gets root permissions and reads a db file of another app (Yes my phone is rooted).
Anyone can give a gist, I forget do I need to create a Service background worker to do the DB reads... Or just need to send the op to a bg thread with a UI callback sorta like Node...
I did try writing a ReactNative app maybe last year just to try it out but can't seem to easily get root access... And the SQLite package is buggy, couldn't npm install on Win10...14 -
Just wanted to do some scripted image resizing for school in school because the teacher asked me to help her with that.
So I thought: Let's just write a tiny script. Written the script in almost no time (just iterates over all jpg's and resizes them)
30sec.
Now I tried to run it. Didn't have my laptop so I had to somehow run it on their windows PCs. At least it's windows 10, unlike other schools that still run XP and stuff so I thought it might be doable. Well guess what, nope it wasn't.
First tried to install imagemagick, that didn't work as only teacher accounts have admin and the teacher was already pretty scarred once he saw me doing stuff in powershell so I thought I'd better not ask to do this via a teacher account and mess with stuff as admin.
Next method: Installing msys2. That worked at least (after taking forever to install and having to mess with the av software to get it to run).
And there comes the next problem: pacman doesn't connect via the proxy so I can't download any packages. There is free wifi but only for teachers, and students aren't going to get access until the school finally has a faster connection because they'd (understandably) cause this connection to be constantly overloaded. I just happen to have access to this wifi network, too, because at least the guys from the IT dept know how bad using proxies under linux is. So I connect via wifi and it works. At least I thought: After running the script it yields weird errors about unsupported arguments even though the command is exactly the same I have been using for years (already checked typos twice)
Then got the idea of simply installing imagemagick on termux on android and transferring the files onto my phone.
Too bad we aren't allowed to attach our own USBs to the pcs. Luckily I got a rooted phone so I simply activate adb over network and connect to it.
After downloading the platform-tools I can't run them because of AV software. Luckily there is an option to add an exception per executable so I do that. After doing that it works.... nope it doesn't. The wifi only allows 443/tcp and 80/tcp, even for internal network devices.
So that's it. I'm simply going to upload that stuff to my nextcloud and convert it at home.
Windows, I hate you!!!2 -
Factory Reset my Nexus 6P, can't get Google Assistant -
So I was using the Android O Dev preview and decided the annoying things in it was just too much so I un-enrolled which reset my device, I'm now on Android N and have been for a week or two, everything's up to date and all but holding the home menu gives me the "Now on tap", I've cleared the Google app and services data/cache, swapped the language to English (US) and rebooted a few times but still nothing.
I'm not rooted and my bootloader is locked, I'm in Australia and had access to Google Assistant without any trickery before...
Not too sure what I'm missing and how to enable Assistant? So freaking annoying not having it and stuff, it was so useful and I miss it3
