General :: A13 Allwinner Tablet Stuck At Flying Android?
Oct 6, 2013
i have a allwinner a13 tablet that has gotten stuck in the process of opening. i had installed clockmodrecovery and uberizer. and was looking for a way to correct root 'permission" that kept coming up when trying to install programs that needed root access. then i messed up.
i was trying to restore factory when it froze. i cannot use buttons to enter recovery mode. i made a back up in uberizer but am unable to find .how to use. also since this is happened i cannot load any driver to recognize the tablet into windoes 7device manager.

I received a generic Chinese table. it worked well for about two-and-a-half months. Then, just recently, I discovered rooting and the wonderful things it allowed you to do. I decided to download a system-tweak app, which included a CPU control. I was a little wary of overclocking my CPU, having heard it may decrease its life expectancy, but finally I thought "What the heck?" and in a brilliant stroke of genius cranked my 1Ghz processor up to 1.5Ghz, and it promptly froze, forcing me to power it down. When I turned it back on, I discovered that it had been factory reset. I re-installed my apps, including the system-tweak app, and decided not to touch the CPU controls for a while. Soon after, while at my sister's talent show, I discovered I had about 30% battery life, and I was still supposed to record her. So I figured I'd underclock it to save the battery.
Unfortunately, as my finger touched the slider, my brother bumped my arm and caused me to lower the CPU frequency to its lowest setting. It became extremely sluggish, almost to the point of being unresponsive, and finally I had to shut it down. When I restarted it, it started to boot but then got stuck on the shimmering Android logo, and now that's all it does. I can't even boot into recovery mode, and unfortunately I had just turned off USB debugging that same day.

Is CWM available for the Eken T01? I have posted this question several times on other boards and never got an answer either way. I just got this tablet and I have rooted it. However I would really like to make backups with CWM like I do with my phone because it has saved my butt more than once

I cannot find out how to add drivers to a ROM
I don't have a backup of the stock ROM, however i have a ROM in which everything apart from WiFi works ( 5 point touch screen, all hardware buttons, sound, screen)
This Q88 ROM is downloaded from [URL] .....
I tried the cyanogenmod ROM from ANONFBI [URL] ..... and nothing works apart from the wifi driver no touch, no volume buttons
I would like to extract the drivers from the q88 rom and add them to the cyanogenmod rom.
I've never been able to get the camera working its the single front camera it doesn't bother me its not very good
I tried this thread [URL] .....
However when i load a driver the ported PORTED JB-4.1.1 rom doesn't boot up
I see it has camera drivers but i dont know how to install them
I have attached a LSMOD from the q88 rom

caused & am now stuck in a recovery boot loop.
- bought a Thomson QM734-8G tablet (Allwinner A13b clone), running Jellybean 4.2.2;
- PC interface worked fine in MTP and large storage modes;
- setup Android SDK & Java JDK on PC and communicate with tablet via ADB;
All OK so far..After a couple of days, I decided to replace stock recovery with ClockworkMod Recovery, so I could start messing about with the tablet.
I found the CWM 6.0.2.8 mod supposed to work with these tablets and, following instructions, determined it was indeed running on sun5i hardware and had 10 partitions (nandj) and downloaded the appropriate version.
I used ADB sideload to install CWM and everything appeared to work OK ... until I rebooted and found myself stuck in a never-ending cycle of CWM-based recovery bootloop.All I get is the CWM recovery console, with a few lines of error & the tablet will go no further.
E:can't mount /cache/recovery/command
E:cant mount /cache/recovery/log
E:cant open /cache/recovery/log
E:cant mount /cache/recovery/last_log
E:cant open /cache/recovery/last_log
CWM functions work properly and nothing will mount through the 'Mounts and Storage' section, although sideload mode still seems to work.Attempts to use ADB sideload to install a different CWM or other recovery image have all failed, and LiveSuit and PhoenixSuit both have issues detecting the tablet (despite trying various versions of each & following instructions precisely), so I can't flash a replacement ROM to fix things.
At the moment, I just want to rip CWM out and go back to factory recovery mode and have a working tablet again! I think the Bootloader is locked and the tablet is unrooted. Superuser or SuperSU don't want to install properly. However, using ADB, it looks like I can get root access in shell (#).

I have a generic Allwinner A13 7" tablet essentially identical to this one. The internal memory is set so that part of it is seen as internal, and part as a fake SD card mounted on /mnt/sdcard. Actual SD cards get mounted to /mnt/extsd.
I find this very annoying for a number of reasons, and would like all the internal memory to be seen as internal with no fake SD cards, and SD cards to be mounted to /mnt/sdcard. If this were one of those tablets capable of running Linux I'd run gparted and do the job from there, but it isn't.
Is there any way to merge the two internal memory partitions into just one?
I'm aware I can edit vold.fstab and invert the two mount points, and I'll keep it as a fallback solution, but I hate the idea of wasting a gig of useful internal space like that.

Recently I have rooted my android tablet and I was exploring what I could do. One guy was telling me about an app that can work with performance in game(ChainFire 3D). He said it lowers the pixels in the game to run better. I tapped the install button and it said rebooting now. It then started to reboot but then proceeded to get stuck at the boot screen. I tried doing a hard reset but it is still stuck. I have also tried flashing the stock rom, but I get installation aborted when I try and install it.

I have a Double Power EM63 tablet from Walmart. I believe it is identical to the Ematic EM63 and the MID-AM789 (Google "AM789" for specs since I apparently can't post links yet). I rooted it using Shaume (It's not in english, I just clicked the button that said "root"). I was trying to improve the tablets gaming performance, so I installed the Chainfire 3D driver, and now my tablet won't boot. It gets stuck on the "DOPO" logo, never gets to the boot animation. I can enter recovery mode, so I tried the "wipe/reset" option, but it didn't work. I think I need the stock ROM or a compatible custom ROM to flash to the tablet so it can run again, but I can't find any ROMs that would work and don't really know how to flash it.

Tablet hangs in Bootloop after installed cm9_nightly_20120721 + protab2xxl_compatibility_1.2.0 startet from cwm 6.0.1.0. Noticed that the "/data" partition only has 15MB of Space with 0B Byte free. I wiped the cache after installation with cwm, i am not able to boot to cwm again because key combinations not work on this device.
Got a T15A Generic tablet which has the same Hardware than protab 2 xxl, Goclever A103, Coby 1042 etc..how to get CM9 or CM10 running?
Code:
--------- beginning of /dev/log/main

I recently acquired an A13 tablet and wanting to install CM10 on it I first installed CWM 6.0.2.8 according to the famous manual (if it's relevant I'll post the exact url). Anyway, it got stuck on CWM (doesn't boot normally). Now I figured it can't install since using 'adb shell' and looking at /proc/partitions -- nothing is there!
"""
cat /proc/partitions
major minor #blocks name
179 0 15558144 mmcblk0
179 1 15554048 mmcblk0p1
"""
So I have no internal memory to use -- no internal memory to install to, right?
"""
ls /dev/block
loop0 loop2 loop4 loop6 mmcblk0 nandf ram0
loop1 loop3 loop5 loop7 mmcblk0p1 platform ram1
"""
Seems that only nandf exists, which means I can't cat into nandg and sync and install new img. Right? Or am I missing something? How do I fix this?

I am trying to use my cheap virtually unbrickable tablet to learn more about kernel development and eventually ROM building.
I have extracted the manufacturers (WoPad) LiveSuit image and used split_bootimg.pl to break up the boot image.
I extracted the config file from the kernel image using extract-ikconfig and it created a config file. I didn't see the config in /proc.
So, I have the factory ramdisk and the factory kernel config.
I have downloaded several kernel sources (lichee-3.0.8, ChritianTroy's 3.0.36, and another one from linux-sunxi 3.0.72). I can successfully compile all of them without errors and they all generate zImages, uImages, etc using the factory config as well as the sun4i_crane configs they come with.
When I repack the boot.img with the newly created kernel and install it on nandc it wont' boot past the android icon (u-boot). When I compare my boot.img to the factory one, they both have the same offset where the kernel starts (0x00000800). I have also ensured I'm replacing the kernel modules when I'm changing kernel versions.
Here is the line I'm using to repack the boot.img
Code:
mkbootimg --base 0x40000000 --pagesize 2048 --kernel zImage --ramdisk ramdisk-repack.cpio.gz --board sun4i --cmdline "console=ttyS0,115200 rw init=/init loglevel=8" -o boot.img
[Code]...
Also, I'm building on Ubuntu 13.04 with Google GCC 4.6 from the ndk. I have built kernels for other devices without issues.

I own a Allwinner A13 7 inch tablet, on which I installed the Cyanogen 10 mod (Due to restrictions I cannot place the link to the mod)
The problem is I probably installed the wrong touchscreen driver, so the tablet boots perfectly into the Mod but I can't do anything. Normally it would be no problem to just put back my backup, but I can't get it to boot into CWM.
In the first place I rebooted into CWM to instal the mod by adding the following command through the "terminal app" before rebooting,
Command: "echo -e 'boot-recovery' > /dev/block/nandf; sync"
Now I cannot use the screen so i cant use the terminal. I also cannot use ADB because USB debugging is standard switched of after flashing a new MOD. Any other way to get into CWM??

Basically I ran Livesuit to flash my Chinese Tab, its called a desiretab has an a10 processor. Anyways the first flash was successful, besides the fact that it didn't pick up touch calibration correctly. So, I decided to flash it again with a different firmware image, low and behold it gets about 50% in and just freezes up. Now the Tablet shows no form of screen output, I attempt to flash it repeatedly, nothing works.
When I say I attempt to re flash it and nothing works, I'm saying that it just sticks at zero and the flash command does nothing.
