Hello, everyone. I'm an Android Developer with some experience in platform development. I've got an interesting task: to teach TWRP to take pictures from camera. I just wanna know if that is possible and what should I start with?

I don't think so. I haven't seen any messages anywhere about it at least. Anyway think twice if you really need it or not. I came to not doing anything to this part of tablet.

Hi everyone. I've got a question: does anyone have a little noise in speaker during the call? This noise sounds like when you get the phone close to a computer loudspeaker during an active call or while loading something with mobile internet. It's not very loud, but when I speak without the...

I'm having some troubles with QtQuick on 5.8.5. (Well, not exactly with Qt, but with one application, that uses it for drawing maps). Didn't have'em on august, 16 build, though. What changed since then, can it be reverted? I think it should be ralated to bacon device tree.

Can you, please, describe in details these things: 1) What Linux did you use for building? 2) What revision of AOSP 8.0.0 did you download? 3) What version of blobs did you use? 4) Did you just download the 2 blobs .sh files to the root of the sources and execute them? 5) What AOSP configuration...

I'm sorry if I misundestood the question. I don't undestand why you should need TWRP because you just get the sources, get the blobs, compile them and get a zip file which can be flashed with fastboot command. So, no TWRP in this process is needed. I still don't know how all these ROM creators...

Well, I don't know about Pixel, but when I had some experience in building AOSP for Nexus 5, Nexus 6, Nexus 9, binaries from Google and Qualcomm were a required minimum to get system booted. And if I wanted to get rid of some errors in logcat, I had to add some additional libraries, but the...

I'm using those that come with Android Studio 2.3.3 updated to latest versions of all components. That's not the problem with slots support - everything flashes without errors.

I did "make clobber". It just removes the build directory like "make clean". And this step is redundant if you never built the system before (with or without binaries). Why make -j9? Because it shows better performance than just make. I know the build system should get the cores number and set...

Hello everyone. I have a problem. I'm building AOSP 8.0.0_r11 for Pixel XL and when I flash the result zip I'm getting a bootloop. How am I building? 1) Select java 1.8 2) cd AOSP_8.0 3) source build/ensetup.sh 4) lunch aosp_marlin-userdebug 5) make -j9 updatepackage 6) wait a couple of hours...

Hello everyone. Can someone help me with building AOSP 8.0 for Pixel XL? What I've done? 1) Downloaded source for aosp_8.0.0_r4 2) Downloaded binary blobs to the root of the source, extracted 2 .sh files, executed each one, so their contents went to vendor folder in the source root 3) source...

I tried Multirom 33e and TWRP 3.1.1.

Hello everyone. I'm getting a very strange problem: after I flash any build of ROM somewhere about since the end of June, I'm getting reboots just after I see the 1+ logo. So, it looks like "power->vibro->logo->reboot->vibro->logo...." and this lasts forever. The problem persists only on this...

hyperUnicorns. For some reason any build I try to install since the end of June gives me reboots. I thought it was some incompatibility with Multirom 33e and MIUI, but after I flashed the full Cyanogen package, nothing changed, that led me to google and some posts, saying it can be a damage of...

Because it was a bootloop just right after a flashed the ROM on a completely clean factory reset device. Now I understand that it was a problem with the ROM, that's why I made a backup. And your image will help me know if I miss any files in this partition and know their permissions.

Hi everyone. Got a bootloop, so had to format the persist partition. I made a backup of it with adb before formatting, but forgot to save permissions/owners of every file. Could anyone just make an "ls -l" in all folders of /persist? Thank you. P.S. I'd appreciate if anyone makes a full image...

Can anyone test if 2GIS application is crashing on any June/July builds? P.S. 2GIS is a Russian Navigation Helper, so I'm mostly asking Russian users, but if this application is available in other countries, feel free to install it. It has English language available. This is what I see in...

Yes, after reflashing everything works fine. Looks like something was messed up in Magisk.

Got a strange problem: no sound when calling somebody. Neither I hear anyone, nor I'm heard. P.S. MusicFX is duplicated for some reason in /system/app and /system/priv-app maybe it's the root of the problems? HyperUnicorns from May, 19 + Magisk v12.0 + nothing else. Flasing A.R.I.S.E didn't...

As a former owner of Nexus 7 2013 will say. 1) Size: Huawei it's a bit bigger, heavier, but thinner. Huawei wins. 2) OS: Nexus 7 gives much more freedom in installing whatever you want, where Huawei reduces your choice to EMUI only. It's not bad, I like this system, but Nexus is a winner here...

You may want to see these two official thread on Chinese Huawei forum: Here you may see some dates when some stagis of distributing EMUI 5.0 will come And here you may try to become a beta tester

For now we have no sources to make a boot.img for M3.

Found on Chinese forum this: open calculator in landscape mode and enter () () 2,846,579 () () = Have a try. maybe it works. They say it's not applicable for LTE version, but maybe on Wifi it will work?

Sorry, I have no idea. I tried ICS dialer and exDialer - none of them accepted these codes.

The code you're trying to enter is for getting Product ID. I think you want this code: *#*#2846579#*#* P.S. there's a lot of dialers on Google Play. You'll need the first code anyway to unlock the bootloader for free, so maybe look for another dialer?

Don't know then. I don't think Huawei made it like: "You forgot your pattern? - Ha-ha, loser." There surely must be a button for emergency PIN input somewhere on the lock screen.

It won't. After you enter the pattern wrong 5 (or more) times, the tablet will block the input and you will see an Emergency PIN button to the right of Emergency call button. If you don't, just lock and unlock the screen.

If you look at the content of the update.zip archive, you'll see that it contains a number of .patch files and update.app. These .patch files are actualy the modifications for system and other partitions (patch file name corresponds the partition). They contain only differences between the new...

Found this solution nearby.

So, well, thanks to all. As I see, there's really no great need in changing OemInfo at this moment. Here're the reasons: 1) You want OTA -> you don't modify the system. Otherwise it won't install. 2) If you have root and did some modifications, it's better to install Chinese firmware than wait...

Oh, yes, sure. Get root, find /system/etc/xml/multiwindow_whitelist_apps.xml file, open it with any text editor that supports root and put there something like <mw_nonsystem_app package_name="xxx.yyy.zzz" /> where xxx.yyy.zzz is you app package name. You can see you package names with 3C Toolbox...

Well, ok. I only quickly looked through the decompiled code. Change dpi with the app then, it'll make a backup of build. prop and try to compare both files - new and backup. I could have missed something. Just to mention, I didn't like the way tablet had behaved after changing DPI. EMUI is not...

If you just need to change density, you'd better try changing the value in build.prop first. And in case of any problems after, change the value of the key I wrote previously or restore the original build.prop from backup. Good luck.

Sorry if I was a bit rude. Try "Pimp my rom" utility. Find it on Google Play. I worked for me and now I'm thinking of how to revert :) Edit: if I got it right, this utility adds (modifies?) this key in build.prop: ro.sf.lcd_density

Why you not reading neighbor topics? Install Xposed, install App Settings module from here for example, activate it and setup whatever DPI you wish.

I have this problem sometimes. In my case it goes away after reboot.

Xposed App Settings is the solution for Chrome and Youtube. Just set 391 density and the highest resolution available and everything becomes OK.

You may have a try, why not? I'm not a ROM developer and I can't say I don't like EMUI (I wouldn't buy the tablet then). If someone gets the sources, it could speed up the development of something more pure-Android. People on 4PDA would be thankful to anyone who brings such a thing and possibly...

Hi there. Is there an option to hide them in Settings->Navigation?

This custom ROM is just a slightly modded EMUI, based on Russian or Chinese official firmware. It doesn't require building from sources and differs only in built-in root, some pre-installed apps and custom boot animation. It's not what topic starter wants.

Thank you but I know what's inside Chinese /cust folder as I am using Chinese firmware myself. I am interested in untouched /cust of US version of tablet because I think there can be some option in local.prop or somewhere else, that blocks 5GHz Wi-Fi. I can try to look for it by comparing...

We currently don't have any kernel sources for this device and not so many people have it, so I think a custom ROM is a question of future.

Huawei devices have two recovery partitions: recovery and recovery2. Recovery has generally all the same features a typical Nexus recovery has, except it doesn't have an option to apply update.zip and has a touch interface unlike the Nexus recovery. Recovery2, called eRecovery, also has a...

Forgive me for not being E.Vogel, but let me explain. Huawei devices are not usual in terms of partition structure. For example, they have 2 recoveries, designed for different things. For a Nexus owner their update structure is also strange. Once upon a time, you could create a "dload" folder in...

Those, who have a US tablet, could you please upload your entire /cust folder somewhere? If Chinese firmware is a solution, maybe there is something in /cust, that blocks 5GHz wifi? I wanna compare it to Chinese and Russian versions and maybe find something interesting.

You may try to flash Chinese firmware. It's Something like BTV-W09C233B0xx or BTV-DL09C233B0xx I don't have any other ideas, really. If even this doesn't help, then 5GHz is locked by OEMInfo or disabled in hardware. Firmware can be found with this tool

C'mon, be the first one :) Just another caution. Please, do a backup first. I had a factory reset after changing region in custom.bin. I don't know, what was the real cause, and now I don't do anything to my tablet, cause everything it setup and works fine. You, probably, can avoid it in two...

Don't quite understand what's this for. First of all, recovery should be the same version as your ROM. I don't know if their mismatch will immediately lead to some malfunction, but some people on 4pda said they should match. Second - stock recovery's functions are limited to factory reset...

Don't know why, but I can mark these files, press 下载 button and files are being downloaded. The problem is it's very slow. Also, I have a link to Full OTA firmware for BTV-W09C233B019: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1224/g490/v67974/f1/full/update.zip PLEASE, BE...

Well, if you have unlocked bootloader, you may try the following: 1) Get root access. 2) Open /system/build.prop and find ro.config.hw_is_hide_wifi_5g=true and change it to "false". Or to true if it's false. 3) If that doesn't work (cause I really don't know what this option stands for), see...
