Hi all,
I have a Yonestoptech BS1078 (ID from motherboard), also designated (Q102 in About Tablet) It's a 10.1" tablet with the quadcore Allwinner A31S chipset
the device came fully rooted. Firmware is stock as originally supplied.
The original recovery I found virtually useless (a known problem with this device), so I looked for a custom recovery on this page ...
http://www.slatedroid.com/topic/106714-twrp-271-recovery-sdk3x/
I flashed TWRP with the the first one on the list flashed via a terminal on the device
... WRONG !, recovery was oversized and totally unusable, the only two buttons I see, Install and Backup do nothing. That was the first mistake, second
was that I never tried to reflash with any of the others. I was told much too late to be of use, that the one for Fusion5 xtra works well on this device.
Next BRAINFOG, sometime later, and the faulty recovery half forgotten, ... one of the main use of this family tab is for downloading and reading our morning
newspaper ... we started having problems with the app, tried a reinstall of that which wasn't the full answer, so went for factory reset of the tab ...
WRONG again, as you'd expect the device rebooted into the faulty recovery, and stuck there, and that's exactly as it is now, each boot up is into the recovery
and no further.
I downloaded the stock firmware from ...
http://vondroid.com/resources/q102-a31s-tablet-stock-firmware.493/#.VbJdsrXppjo
All attempts to flash this have failed, I've tried with Livesuite, Phoenixsuite, PhoenixUSBPro, and Phoenixcard
I should add that device shows correctly in Device Manager as "Android ADB Interface", so I don't think drivers are a problem
I've tried to reset using Android Multi tools also GpGTools ... no joy
Last thing tried was to flash fastboot for Allwinner devices from
https://bugzilla.mozilla.org/show_bug.cgi?id=1026963 ... no joy either.
From these results I suspect USB debugging isn't enabled, but can't be sure if I ever looked at that when the tab was working.
I do read that Allwinner devices are virtually unbrickable, whatsay Guys have I created a brick with this comedy of errors ?, is there hope ?.
Re. my capabilities I have a little experience of adb, and rooting tabs phones etc. I'm no expert, but can usually follow instructions.
Apologies for long post, thought it best to give the full story. ... J

Hi,
I need some help with unbricking OEM U9GT3, also known as D97/97S. This is chinese clone tab with RK3066.
I had some issues with battery, so I tried to flash various ROMs. After I flashed ROM from NextWay tablet my device died.
Literally died. No response to POWER, USB, Charging. Can not put it into recovery. Obvoiusly PC doesn't see it.
I found a tutorial about unbricking WINDOW 70dual, but it says something about the contacts on the mainboard. After I opened my tab I can not find that were mentioned.
I tried also another tutorial adviseing to shortcircut 29 and 30 pin on one of the chips. It didn't work either.
I replaced battery. It didn't change anything.
The most important now is what to do to a tab to make it visible for PC. I can manage with the rest.
I can provide photos of mainboard or any further information if needed.
Any idea is very appreciated.

hi
has blocked the tab .... happened to me several times with my pipo s1 .... how to revive it is simple .... you have to put the original ..... firm or .... firm that you know works .... Once done ..... remove the battery for a minute and then reconnect the battery .... normally turn the tab ..... supposedly should work .... flahear remember before the rom that works .... delete ID
Yeah well cool advice.
But how can I possibly flash ROM that works when my PC DOES NOT SEE the tab? If I could flash anything I would do it.
Question is how to reset tab to erase nand flash and flash new rom.
Hi guys, I bought the above phone off Amazon. I found out this very strange device also had a root-enabled kernel out of the box, but my question is about recovery. I want to install CWM as a first choice, if not that, TWRP, but a Google search only tuns up loose references to MTK6589 which is presumably the SoC, but nothing for my specific model. Currently when I reboot to recovery with any root app it shows 'no command' (maybe there is no recovery installed to the recovery partition?) and when entering bootloader mode the device displays what is seen in the attached photo.
I would appreciate any help on getting a working recovery set up on this device.
Thanks!

Hi, I also have one of these phones and have been looking at recovery options with little success.
However I have found a set of instructions in the XDA University about porting CWM. (unfortunalty I can't post a link due to being a Noob, but if you Google 'porting cwm' it should be the top result).
I am going to be attempting to do this once I have got my PC set up dual boot for Linux.
Will post back with news on how it's going. Would appreciate any progress you have made about a recovery option.
Regards
Mad.
first, make a backup of your device using mtk droid tools.
if phone isn`t rooted yet, use this tutorial:http://forum.xda-developers.com/showthread.php?t=2332783
for the recovery, you need to unpack your recovery.img, take the kernel zImage and put it in the cwm-recovery. for mt6589 phones, this one should work: http://forum.xda-developers.com/showthread.php?t=2357875
you can unpack/repack your boot.img with this tools:
http://forum.xda-developers.com/showthread.php?t=1587411
after obtaining new recovery.img, flash it through SP flash tool or mobileuncle tools.
Recovery Quirk
Chrizzly, thanks for the pointers, will be checking out the tools tonight.
Found a quirk though, may just be my phone.
I booted into recovery last night and as expected the "no commands" came up, but then I took the back off the phone and a recovery menu appeared. Had options in there like reboot, delete cache, delete delvik cache....
I'm assuming this is the stock recovery.
I tested it again this morning and booting into recovery and then taking the back off the phone made the menu appear!!
Any one else care to test and see if it's a stock thing or just a quirk of my phone.
replied before, my post disappeared.. this isn`t related to your device , this is recovery-typical. it is showing the android first, without a menu. you need to press hardware buttons, to get into the menu( this is device-specific, you need to try that, also buttons on the touch screen, if there are some) this will usually bring you in recovery MENU. think you accidently pressed one of these buttons while opening the device.

Re: Stock recovery. Thought it was a button press that got me in first time but I tried it several times and no button worked just pulling the back off. Little puzzled about that but it's something I can live with!!
lovelord:
Re: Files. Thanks for the files, going to try them out as soon as I can!!
Done
I have got CWM working on my i9389 now, there was a few quirks in getting it going.
The method I used was as posted in the MTK Droid Root & Tools thread by rua1.
TIPS
Leave the battery out when doing read back or flash in Flash Tools.
Not mentioned in the instruction is the MTK vcom drivers which you will need and can be found in the Root tutorial posted by Chrizzly a bit further up.
Make sure you read the instructions by rua1 closely and use the images posted as it's not always straight forward.
Last tip pay attention to where MTK tools puts the files it creates, had me stumped for a bit!! I've never been very good at following instructions!!

I managed to boot loop mine while messing with a ROM I made (it's not finished yet) but managed to recover by re-flashing using the Flash Tools a back up I had taken just after installing CWM.
Do you have a back up you can flash?
I have just checked mine and even zipped it's still 800MB so I can't email it to you...
...sure if I looked about I could find somewhere to upload it to for you. PM me if you need this!!

Hi,
i have Dmtech tablet 1032dc. I have not tried to flash, upgrade or anything, it just wont work anymore. Last time it worked was everything ok, was shutted down properly and placed in a box.
Now it is stuck on load screen, i have tried factory reset, sometimes it freeze on formatting data, other times it finishes wiping data. But after restart boot logo hangs as before. I have tried to connect to pc with a usb cable but it wont show any devices in device manager (only if is turned on and stuck in loading animation it shows 2 removable devices as partitions, who cant be accessed). Tied Win xp and win 8.1.
CPU: aml8726-mxs 1,5 Ghz
Android 4.1
Recovery system is original
What steps should i take next in order to make it working again?
All i can think of is to flash original firmware with sd card, but i cant find any roms of this device. Pls help.

hello everybody...
i have a (spanish jazztel) i-joy 10" tablet, cortex a7 quad core.
i made a mess with titanium backup and when tried to recover factory settings i realized that i had screwed the recovery data.
system would boot up, tablet would work but with many errors and "stopped working" pop ups.
i looked for a stock rom just to find out there is NONE in the WHOLE INTERNET!!!
then, googling here and there i read about some compatible roms, from allwinner, kalley and other chinese brands.
i downloaded all img files i could find, i flashed them correctly with phoenix usb pro, one after another.
first two worked well except for the cameras, that wouldnt work.
then i tried ICOU10GT firmware, flashed correctly...but touch DOES NOT work, i cannot go any further from welcome screen since the touch screen is not recognized.
i am 100% sure is not a hardware problem, all physical buttons work, screen works but not touch.
since i cannot reach the "enable usb debug mode" option i cannot flash any other img.
when entering recovery mode, if i choose update from adb the tablet is not fully recognized by windows (driver says device cannot start).
i´ve tried sd burning with phoenixcard but doesnt work either, tablet doesnt boot up from external sd card.
is there any way to recover this working-but-bricked tablet?
please help!!!
------------------
if there is not....is there a 100% safe and sure way to commit a "perfect murder" with the tablet to send it to post-service and being able to claim "it just stopped working" and them not being able to see i flashed it? i guess you know what i mean.

Hello elders. I hope that I'm in the right session for my ask. I have tried to update my tecno 7c android 5.0 based tablet (that I've bought, just a month ago) cause it proposed it to me in the settings, software update option. Everything went well till the end of the download. After that, my tablet rebooted correctly and came to the android home screen. But each time I put any SIM card inside, I always have this message: "com.phone stopped working". I've tried to perform a full reset of the phone through the stock recovery but I don't even have access to recovery now. The phone is MTK 6582 processor based tablet. I've tried to read on internet to see if there's a way to fix it but the one I've found explained that I need a same working tablet whose backup file I'll flash on the bricked one through SP FlashTool to revive it but I have nobody having such tablet. Help please if you have solutionq for me. Very urgent. My tablet, the only on I have! Thanks in advance.
Hello! Nobody to answer me?
