[Q] Allwinner A10 - Android Q&A, Help & Troubleshooting

My allwinner A10 tablet came pre-rooted or so I thought. I installed CWM v6.1.0.2 via the terminal emulator but wasn't able to reboot back to my OS.
I then wiped cache partition and wiped data, it would not allow me to wipe the dalvik cache.
At the end of each process I see:
E:Can't mount /cache/recovery/log
E:Can't mount/cache/recovery/log
Also for /last-log of the two above.
I have got an A10 cm10 rom which I have tried to install via the external sd but no luck.
Any help would be appreciated as I have no clue what I can do next.

Do you know the model or make of your device? What are all of the specs? If you have that information I can probably lead you to a support forum for your device.
I recently recovered my A10 device flashing a .img of a totally different A10 tablet and most of my tablets features work. I tried flashing 100 other .img files and none of those worked correctly.
Where did you get that CWM file? Was it CWM that was specific for A10 devices? You can't just flash any recovery to your device and expect it to work.
Your issue is likely that the CWM is not for your device or it's just having issues with your device. I'm using CWM 6.0.1.1 for Allwinner A10 ICS. I got it onto my device using a simple one click method, but in order for you to use it you have to be on a rom that at least boots up with the display working.
Once you give me information on your device I can try searching for some .img files for you to flash onto your device with Livesuit. If you're lucky enough you'll get one that is specific for your device, if your not so lucky you're going to be breaking your head trying to find a rom that at least boots up with most features working. It's a lesson learned, don't mess with your device unless you have the necessary resources as a backup in the event that something goes wrong.

Okay, if we both search we'll find the device faster.
Go to the following link and try to find your device or a device with similar specs: http://www.slatedroid.com/forum/274-allwinner-a10-cpu-devices/

Again thanks for the help, where is the spec for all the models on those pages?

To be honest it's just a long search through each tablets board to find a post that lists the specs. I'm realizing that's a big headache.
I personally just flashed random A10 images onto my device. Nothing bad seemed to happen to my device, but I'm not sure if the same is going to apply to you. If you feel like taking the chance you can just flash some images and cross your fingers hoping it doesn't do anything to your device. When I did it the worst that happened was that the roms either didn't display anything, displayed a static image, display was off center, touch controls didn't work, or got stuck at boot screen, then one finally worked.
I can try to link you to some A10 firmware images and LiveSuitPack if you want to take the chance.

If I knew how to do it I could persevere trying different images, how easy is it?

It's very simple actually.
Here's the LiveSuitPack tool: http://www.topnotchtablets.com/LivesuiteInstall
Here's the guide for installing firmware: http://www.topnotchtablets.com/A10Firmware
In the guide for installing firmware substitute the menu button for volume down button if you don't have a menu button.
There are two firmwares to download on the firmware installation guide page, although I don't think either of those will work at all to begin with. Try them if you'd like. Give me a few minutes to boot into my other partition so I can get all the links of images I bookmarked.

So the drivers are in the folder? for each particular tablet image.

No, once you download the Livesuitpack you're going to open the folder and run LiveSuitPack_v1.07. That'll install some drivers, or it'll ask you if you want to install some drivers, click Yes. From there you're going to run the LiveSuit application. Then you follow the steps for getting the new firmware onto your device.
EDIT: The drivers that the Livesuitpack installs onto your computer also make your device recognizable in ADB (if you know what that is and ever have a use for it). I also couldn't find drivers for my device for the longest and these seem to work at making your device recognizable across your computer.

No need to thank anymore than you already have. I've been helped around here plenty of times by some sincere people. It's all about giving back what you receive. I hope everything goes well with your tablet as it did mine, and be careful, don't want anything getting messed up on you. Good luck.

No luck so far, I flashed one image which gave me a sort of cracked looking screen affect, other images I have tried to flash do not make it to 100%?
I am not sure if I have now completely bricked it?
I am still looking for images that closely match my pad and will try again this evening.

Your device shouldn't brick. I believe A10 devices have all necessary code in the chip itself, or something along those lines. The cracked looking screen effect means that it isn't compatible with your device, I came across plenty of roms that did that to my device, all you do if flash the next image.
I haven't come across any issues with it not getting to 100%. I can only suggest you retry it, or move on to the next image.

Iv got similar problems with my BC1077. Iv been trying to fix it for the last few days. Im not 100% sure, but I think the problem Iv quoted above is that CWM does not support jellybean, so it wont work with cm10, which is jellybean.
Over the last few days Iv flashed 40+ A10 firmwares to my tablet, but Iv only found 1 that installs properly and boots for me. It actually works pretty well, only major issue iv noticed is auto rotate doesnt work. But this same working firmware is also jellybean, after I install CWM I get bootloops and have to reflash the firmware again to boot.
Heres a link to the firmware that works for my BC1077 - http://www.ssb-repair.com/Firmwares/Cherry/M1007_20121217.zip
Its for a completly different tablet (Cherry Mobility - M007), but like I said it works on mine.
Heres another firmware it might be worth you trying to flash, its the only BC1007 specific firmware Iv found, but it wont install on my tablet, I always get a 0x162 error from it. Heres the link - http://www.pandawillforum.com/soft/mate sku20314 firmware for May 25 stock.rar
Good luck, let us know if you make any progress.

I think I might have been flashing with a very low battery, if a flash was unsuccessful halfway through would this not brick the tablet.
I am not getting any kind of response from the screen at all and when I try to flash although the drivers appear to load the % bar doesn't go up.

Thanks for that, I will try tonight and get back.

OK, regardless of the image I try to flash the livesuit progress bar gets to 3% and then goes back to 0% and then nothing.
Anyone?

---

If the battery was low and the flashing process didn't finish all you have to do is load up the exact image that didn't finish flashing into LiveSuit and put your tablet into download mode and let it do its thing. I had the same problem and got scared my tablet was bricked, so I just did the process I stated above and it finished. It wouldn't allow me to flash another rom, I'd get the little Livesuit pop up that you get after a rom successfully flashes, so if that's the same pop up you're getting don't be alarmed.

I dont think your tablet is bricked, if it was I doubt it would respond to Live Suite or PheonixUSB pro at all. From what Iv read about the A10 its meant to be unbrickable.
What error codes does live suite/pheonixUSB give you when they stop?
if youre getting 0x120 and 0x162 errors, just keep trying more firmwares out till you find one that will install without errors.
Theres loads of A10 Allwinner firmwares at this link - http://androidtabletfirmware.com/firmware_search/order=2/sort=1
