Questions about A13 Allwinner Tablet - General Questions and Answers

EDIT: Hello all, I just wanted to update this post. I did some intense researching, and found out that I could download CWM (the A13 variant), and it worked. However, I don't have any physical buttons, so nothing works execept the power button which reboots it. I have attached photos, to see what I am talking about. If you can help out, or know what direction to point me, I would greatly appreciate it
Hello all,
I am going on a long shot to get this answer, but it is worth a try. I know this is not a name-brand tablet, but it was a gift, and I would have to have it returned. So, I am going to just get to the point. I have already rooted the tablet, and have rooted apps up and running. My first issue is that the Youtube app does not work properly. With ANY video, it plays, but there is no video, but the sound is perfectly fine. I thought this might have been a video hardware issue (or rooting issue), however, this is not the issue. I have used JoeVLC to play many video files, and downloaded another browser and when to Youtube and played using flash as well. So if anyone could answer that, it would be great.
My second question is an actual root-question. This tablet is the EGS004 model with a 1.1ghz single-core and 512 of RAM, just to give you an idea of what I am working with. One thing I noticed is that it does not have any volume buttons, so a recovery may not be possible. But I would really like to flash some files. The way I went to root this device is by using the Cydia Impactor method, which worked flawlessly. I am not expecting a ROM, but I would like to cut out the "middle-man" and just run on pure android power. If you have any other idea on what I can do, I would greatly appreciate it.
Note, I have rooted MANY devices before, so I am very familiar with the process and how it works, but not to the knowledge on doing it by myself obviously. Thank you for my help.

I have the same problem with the Youtube App. It was working fine before I rooted the tablet, so I'm guessing it's a rooting issue. I've tried this app from the Play Store called "Video Tube" and it seems to play YouTube videos quite well, but it has a hard time scaling the video to the whole screen on some videos (The video itself is centered and has black margins around it).
Accessing Recovery will probably be quite difficult to do on this tablet. However, I installed the xposed framework and GravityBox, which gave me access to the advanced power menu which has an option to reboot into recovery. But I didn't try it yet. (Since I don't want to break/brick it since I use it for school & note taking )

Hi,
I've also an ALLWINNER A13 tablet ... I'm not quite sure if we have the same version but anyway, as I read your post, I installed the youtube app from the playstore (version 5.3.32) and it works fine, video playing - pushing the playing video arround ...
.. oh, perhaps important, my tablet is not rooted ^^

PS: You might post your tablet kernel version info, than we could compare :highfive:

My kernel version is 3.0.8+ (at least that's what Settings -> About Tablet says)
I managed to install CWM 6.0.2 and reboot into it via the advanced power menu which is part of the GloveBox mod for Xposed Framework.
By default, you can't do anything except reboot the system by pressing the power button. BUT, if you plug in a USB keyboard into the tablet, you can select things using the arrow keys and use the Enter key instead of the tablet's power button. That way, you can do whatever you want in recovery mode. Only problem is that it keeps saying "E:Can't open /cache/recovery/log .... (and some few more lines that are simmilar)"
I got the files from here: http://forum.xda-developers.com/showthread.php?t=2189640
For mine it was the A13, 11 Partitions Zip.
I'll probably attempt to flash the Cyanogenmod 10 for A13 devices on it

Erm yep Bricked
I followed the instructions and everything but it went wrong I guess.

[Q] Livesuit Image For Stealth Pro 9.7C

Hi. Just wondering if anyone out there would happen to have a .img image of the firmware for the trio stealth pro 9.7c. I.ve looked everywhere and can only come up with images that install through CWM recovery. My tablet will not boot into recovery as I flashed a rom that I thought would work, but now no video. Not an emergency, but if someone has it, it would be much appreciated. Thanks in advance

I used a livesuit image that was supposedly for the 9.7 on my 9.7c and everything works flawlessly. Use at your own risk. can't post links. pm me if you want it
Try this.
A member called hammerite said in this post http://forum.xda-developers.com/showthread.php?p=52298998 that the firmware for Wintouch Q91 works with this tablet. Specifically the file name is Q91A30321.img. Google it. I'm just downloading it right now and hope to fix a friend's tablet with it..
Sorry to say that file didn't work for me.
Another works, kinda

Yeah didn't work for me either. But I did find a bit of a work-around to have a functioning tablet again. A bit of a pain in the butt way to go about it, yet it is usable. If anyone wants to give it a try so you can at least use the thing, I'll try to explain it.....here it goes.......
Things needed:
1. LiveSuit or PhoenixSuit (I used PhoenixSuit)
2. Not necessary, but useful later, Root_with_Restore_by_Bin4ry_v32.zip
3. F918-WCDMA-20130423.1.1.11-a106-dou0308.img (copy and paste this into google, you will see a link from a site called pan.baidu.com on the first search page. Turned up about the third search down during my search. It is in Chinese, but the download link to click will have the file size, (310.16mb) click it and another box will appear, click the white box on the right, then yet another box will appear, click the blue box on the left this time, then it will give you the download.) This image is for a ly-f918 tablet, but mostly functional on 9.7c
Now we can start flashing.......
1. Using either LiveSuit or PhoenixSuit, flash the image that you downloaded to the tablet.
2. After the flash, you will notice that the screen colors are messed up and screen rotation is 180 degrees off. For the rotation, I just turned off auto rotate.
We will get to the color issue in a few....The screen will be barely legible at this point, but if you squint just right, you can read it
3. Run Bin4ry to gain root
4. For the screen color issue, I signed into google, went to the play store and downloaded and app called Screen Adjuster Free, ( yes this rom has play store built in) Set the Screen Adjuster to on (box at the top of the app) and set the system brightness to 23%. The screen should now be legible.
Things that are NOT working:
As mentioned, auto rotate is off 180 degrees
Rear camera causes the tablet to shut down
Volume up button lowers the volume, volume down and back buttons do nothing. There are volume up/down icons on the notification bar though
Color still off in the notification bar
I know it seems half-assed, but I DO at least have a working tablet again!!
I did find another rom that touch, wifi and camera do not work, but the screen colors are right:
sun4i_crane_v1.5_T05A_mc32x0_20121012-tm2.img
Maybe if someone knows how to open the images to play around with them, the display driver from the sun4i rom can be put into the F918 rom so the color is right. And possibly fix the screen rotation issue. Then the only things to worry about are the hard buttons and rear camera at that point.
Sorry if this seems lame, but like I said, My Stealth Pro 9.7c is functional again ( to some degree any way ) and if you were in the same boat as I was.....holding a tablet that didn't work at all.......it's better than nothing.
as always, try at your own risk. Let me know if anyone has trouble with this method or improvements. Thanks!

Just noticed you posted this as I was writing my post Does auto rotate work right? and do the hard buttons fuction correctly? and rear camera work? If it does you're a step closer than I was. maybe if someone takes THAT rom and the second one I posted and made a flashable image, we would have a completely working rom!!

Ya it's kinda the same as the one you were using, auto rotate is off 180 degrees, but no auto rotate fixes that been, testing it for awhile and found that utube, and netflix auto turns it upside down, and I have to use that other program to get the colors right, camara worked for a bit then it stopped working, but the play store worked just fine, sorry I've been gone, just busy at work =( volume up doesn't work but volume down does

[Q] Two cm12 Q's

I'm running cm12 on my rooted notepro P900; it's a beautiful experoence. I've noticed two things and was hoping for some guidance...
1: Even after a total cold boot up, i will always have youtube show up in the running applications list. At one point I kept it from auto starting via a 3rd party program, but it made you tube unusable. Are there other ways?
2. When I adjust the volume from either my bt keyboard or the hardware buttons, the slider completely obliterates whatever else is on the screen. In a few moments it goes away and everything else is still there unharmed, but it is jarring to say the least. Since my device doesn't have an arm processor, i cant use the xposed mods that ive read are out there. Any ideas would be awesome.
Thanks!

All Exynos 5 Octa core use ARMv7 instruction set. Does ARM mean anything different? Xposed + Lollipop TouchWiz stock rom = bootloop (Pretty nice if you're bored). For CM12 xposed should work on Samsung devices.

[Q] Camera and lamp won't open

Hi everyone, I've look everywhere and I'm kind of desperate now
So, I've had my nexus 5 since it came out here in Europe, never had an unsolvable issue (thanks to the internet), but right now I'm stuck
MY PROBLEM :
One day (just like this, I don't remember doing anything special with my phone), the camera completely stopped working, along with the lamp.
DETAILS ABOUT THE PROBLEM (The situation right now) :
1. Camera doesn't show up in the application drawers
2. It DOES show up in Settings/Applications, and in "My applications" tab from Google Play, but I cannot open it in any way. When I could, however, it would just crash away.
3. I am also unable to access the stock lamp from anywhere (quick settings, etc.)
THE INITIAL SITUATION AND THE EVOLUTION OF THE PROBLEM :
1. I was running CM12.1 (nightlies) on my Nexus 5, and I beieve it occured after an update, but I don't believe it really has much to do with it. When I tried to open the camera, it would show me "unable to get a link with the camera" (translation may not be exact) and the system lamp had disappeared
2. I tried to downgrade the phone, to an earlier nightly, but it didn't fix it.
3. I've donne every kind of wipes : Data, Dalvik, Cache, even Internal Storage
4. After a full Internal Storage Wipe, I reflashed fresh Marshmallow images from the official website, unrooted, reflashed stock recovery, relocked the bootloader and used the system factory reset again on my phone.
5. After this, the problem changed a little bit. The lamp is still impossible to find, but however this time the camera is too. What I mean is, on CM, it used to show up and crash, now I can't find it in the app drawer (See DETAILS ABOUT THE PROBLEM)
I think that's all, so yeah, this one is kind of a challenge.
If the solution is software... Well i really dont know what I could try else; if it's hardware, I'm not afraid to open up my phone. (however I'm a complete noob)
One last thing, I've contacted Google, but the phone they sent me back was in such a bad state that I'm keeping mine (or getting them to send me an other), because the power button was really used, and the lowest part of the screen really "white" (brighter than the rest, my guess was it had fallen)
Thank you very much !
Hi, looks like we have the same problem. Unfortunately I have no solution for you, either. I have ordered a new rear camera from ebay that should show up here end of January. I'll let you know if that fixed the problem.
As you can see from my recent post, I am also having the same problem. I have also order a replacement rear camera from ebay and I fitted it. It worked for one day and then it also stopped working. I am not sure whether it is worth repeating this experiment or I'd just be wasting money on replacement cameras. So annoying, because, apart from the camera (and the torch), the rest of the phone functionalities are still perfectly fine.
Has anyone tried to use a different camera or torch app?

ANOTHER Fingerprint Hardware Not Detected Issue

Hey guys
So i had this problem a while back, it also attaches to video playback errors (YouTube app mainly) and the camera app
So I had this issue a while back, I was unlocked, rooted, Xposed - the lot and i was able to find a fix that got them all working correct again (think it was DRM patch but truly don't recall)
Anyway, I decided to go legit again, use Android Pay and mobile banking etc and I'm now unrooted, twrp is gone and used flashtool to lock my bootloader, but in doing so the error has eventually come back (all 3) but in the process of trying various fixes I have found one cause when I load this one game (it happens after a length of time that I've not been able to determine yet, but loading this game will trigger it 100% even moments after a fresh boot)
Im running stock 7.0
Kernel: 3.10.84-perf-g1016077 [email protected] #1
Build Number: 32.3.A.2.33
I remember when I was first rooting I had flashed some different kernel but was all so long ago i have all but forgotten what I did :/

Fill out the details please, you're not even mentioning the game in your rant (or spilling out your thoughts)
Lol, my apologies, I didn't mean to rant, the game I mentioned was township
I will eventually get the YouTube black video, fingerprint hardware and camera in use glitches sooner or later even if I don't open the game, it's just a sure fire way to trigger it
I also tend to get the YouTube glitch as soon as the fingerprint glitch appears
Is there any other details you need?
What are the glitches that you mentioned? ''get the YouTube black video''?
There's another threat in this box suggesting that flashing a patched kernel fixed most of your problems. Be sure to check it out and be more specific on your ''glitches''.
https://forum.xda-developers.com/xperia-z5/help/fingerprint-scanner-video-recording-t3630726
Sorry, the main glitches I encounter (that all happen at the same time) is the fingerprint scanner stops functioning, the camera functionality stops (no pictures or video, app acts like it's being used by another process) and any video playback is just a black screen, but I still have audio playback and control over skipping through to various times
Will this be an issue flashing onto nougat? I didn't see mention of anything past mm

Try flashing a patched kernel.
I'd suggest a factory reset (if you haven't unlocked your bootloader) or a full swipe (including system) in twrp (if you have unlocked your bootloader) and reflash the newest build.
If the problems still persist, i think it's best to have your phone checked for hardware problems.
And no, it's not a Nougat problem.
Good luck with your phone.

[HELP] Camera won't work after Android 11 Update + Possible Cause?

I was previously on android 10 i believe just a few days ago and my camera was working just fine. The other day I got a notification telling me to update to android 11...so i did and didn't think anything of it.
I use my camera alot for photography so this is very important to me, google camera or any app that uses your camera no longer works.
Example 1: As soon as I launch google camera it just crashes.
Example 2: Snapchat, instagram, or any other apps just give me the error like "snapchat was unable to open the camera".
I know a lot of people are getting this same issue because if you go to the play store and go to google camera app and sort reviews by recent tons of users are experiencing this.
I have two theories on what's causing this.
Theory 1: I've been using an app called "lens cap - disable camera" for over a year now just for peace of mind, I guess it used some sort of device administrator priveledges to block all apps from accessing the camera.
I believe I had the lens cap on (camera disabled) before and when I started updating to android 11 and I think that may have caused a weird break in permissions that somehow has me permanently unable to use the camera anymore.
The reason why this is something I suspect is because according to the developer of that app "android 11 removed most of the functionality of device administrator in favor of enterprise work profiles" (not sure what this means) but I think for some reason this caused it to get permanently blocked.
I have the github page for the apps source code if anyone can possibly look at it and see what exactly the app was changing in the first place because then maybe that way someone can possibly come up with a way to fix mine and many others cameras.
Edit: Apparently I'm not allowed to post links on a new account but the program can be found on github called LensCap by a user named percula
Theory 2: Android 11 just broke the camera by itself and the lens cap app maybe has nothing to do with it.
Ive already done all the obvious troubleshooting like resetting permission/preferences, restarting in safe mode, uninstalling and reinstalling camera apps + clearing cache and storage etc
Sorry of my formatting or grammar is sloppy at all I've had a long day and I just really want to get this working again
If none of your troubleshooting fixed the issue, I think the next option is to do a full reset (using recovery - not the selection in the settings menu). Another alternative is to flash the full factory image and allow it to factory reset the phone as well.
This will mean loosing all your app data and pictures, etc, so back up before you do it. But I am confident it will fix your issue, regardless of the actual cause.

So would you recommend doing "recovery" or "flashing"? Also how do I get to this "recovery" thing,
originally I was thinking about trying to downgrade back to android 10 but from what I remember the steps looked really confusing ;w;
Apparently a lot of people are getting this issue but in the end they said they had to try and RMA it, so I hope recovering or flashing fixes it, kinda worried this update actually permabricked something in my phone.
sorry if its a dumb question I don't know much about phone stuffs
thank you for your response.
There's definitely an issue with android 11 and the camera.
I didnt have any issues on the beta 2, 2.5, or 3. But upon installing the public, official version.. the camera fails. I've tried 2 factory resets. I've installed the ota.zip via adb sideload. And then did a complete format and install of the full image.
Here's what issue I'm having, personally:
When I open the gcam app, it freezes for about 15 seconds. Then I get the "not responding" screen. If I hit wait, about 15 second later, I get the camera on and it's images are on the screen. But it's so laggy that it's not even functional. For instance, If I try to zoom in, it's about 20 seconds until it actually does. Same for taking a picture. I have sent bug reports to them.
I'm gonna downgrade to a better/smoother version. Probably a custom android 10.
Like others, I use it24/7. The pixel 3a is an incredible camera. I hope it's fixed soon.
I don't even know where to post, I came here looking for a solution, but looks like there may be none, other than going back to Android 10 and never ever installing any kind of update on this phone.
I bought the 3a because of the camera, and because I was taking crappy quality pix of my toddler with my previous phone. A9 worked great, A10 worked great. Camera almost instant, switching from Camera, to Video to Portrait, no problem. Message that A11 is available, so hey why not, it's not IOS. Wrong. It totally screwed me, the camera takes from 1-8 seconds to start, to switch between modes. If I double click power when locked camera start (with delays), I then turn it off using power button, when I unlock the phone the camera app is open.
Sometimes when I open it a second time it stays on the setting I chose before (i.e. portrait, or video - not camera default - this would be a nice toggle in the options though - say if you always shoot portrait).
Portrait mode has reversed the picture order (left/right - blur/no blur).
I have missed many shots of my little one since I've upgraded because of this garbage update.
I have a lot of apps that aren't the "latest" version, that work as I need them to; can someone suggest an app that will let me back up my exact versions, then reinstall them after? I have no idea if such a backup/restore app could also save the app data; I don't have root
Also, if someone could point me to a post which shows the way to switch back to Android 10, step by step, I would appreciate it. If I need to reload all the apps and info, I might as well go back to a known working version.
I have also noticed that some other apps are acting funky now. A once rock stable and reliable phone, these days I just want to throw it straight down at the pavement with all my strength... often...
I have the same issue. Have you resolved it yet. My camera app is working but other app using camera gives error.i had also lenscap and problem arised after update to android 11
