So, for Christmas my daughter's mom got her an A33 Q88H QuadCore Softwinner tablet, and we discovered the OS it came with had some very strange issues related to a lack of compatibility with Google Play, so I tried to get around that with software, but I needed to be rooted. However, I had bizarre difficulties with SuperSU, unlocking the bootloader, rooting, and even more difficulties trying to flash a custom recovery that I could use to ROOT-- the obscure china tablet had no TWRP or CWM support. I finally tried a very convoluted method of flashing what appeared to be a ROM for the A33 Allwinner tablet, which hadTWRP already installed, so I could use TWRP to root it, and then finally fix the software issues.
However, the process didn't work, and when I rebooted the phone, I found it stuck on a black screen with a tiny android symbol, and that's how it's been since. Holding volume and power button only reboots it to the same screen -- no bootloader or anything, so I can't find any way to try to flash a factory ROM to get it back to regular settings. When I plug it into my computer, it makes the input noise, and shows up in Device Manager as "Android Device" with "Android ADB Interface" drivers successfully installed, but ADB doesn't recognize it as a device, and I can't get it into any sort of download mode -- it isn't recognized in My Computer as a hard drive. So, I can't find a way to interface with the tablet to reflash a stock ROM. :frown:
It's her Christmas present, so I don't want to admit that I've broken it; I've been trying to solve it all night for 12 hours straight, but I just can't find anything that works! Is there any way you guys can help me? :crying:
I tried to attach some pics but the uploader isnt working.

Hi Guys! I usually lurk around here, but now I really need some help.
Basically I have a Rebranded Chinese Tablet called "Tabulet Mech" and it's a redesign of a M701 tablet.
With a bit confidence of rom flashing, I tried flash a rom from a forum which talks about this type of tablet. With careful action I tried flash the rom using FWDN, and miserably failed T.T
while flashing on FWDN I used "Low format whole memory before download", so I guess the FWDN is formatting the whole tablet.
I dunno if I did something bad while flashing it, but since I didn't see any Recovery Mode available for the tablet, I can't exactly recover my tablet at all.
And now, I don't know if my tablet is already turned off or not, since the tablet is still heated up, and when I plug my USB on it, my PC still detect it (even my Moborobo), but since there's nothing on the screen, well you know I can't figure what's happening.
So my question is, is there any way I can install any rom to just make the tablet back working again?
Hello guys! I have a HUGE problem with my Q88 Allwinner A13 tablet.
I installed an application on my tablet called Z4root, and I wanted to root my device. Two options came up and it said:
Permanent Root
Temporary Root
I clicked Permanent Root because what's temp root anyway?! Big mistake.
So, once it so called 'rooted' my device, it closed itself. I assume it was done. The app told me it would reboot but it didn't. So I turned it off and back on again.
Apon turning it on, I realised booting took a rather long time, but it got to it eventually! But here is when things started to go wrong. There was no Superuser app/folder. It had completely reinstalled a new os (I THINK) onto my device. But this O.S (I THINK) is buggy as hell. It FACTORY RESETS every time I turn it on, can't install any apps! As far as to my knowledge, it has NOT rooted either. When I go onto settings to check on my INTERNAL STORAGE, it says 0.00B on it, when the tablet came with 4GB?!?! So, thats messed up.
Then I thought to myself, FACTORY RESET! So, I rebooted into Recovery Mode from the Settings menu. I cannot get into it any other way as far as to my knowledge. As it booted up into Recovery Mode, it came up with a picture of an android DEAD with an red ! mark. Type down ON Google Images "android boot red triangle exclamation mark" It's that. I have waited FOR AGES for the options to pop up, but nothing is there. Only the picture. So, I can't do anything about that.
As I reboot, it is factory resetted again.
Also, plugging the tablet into my pc dosen't help I think because the Android driver "Did not install correctly". So I message the person I bought it from to provide me with the driver for the Q88 Allwinner A13 tablet. Got no reply.
What do I do? I don't care about my files, I just want a working tablet. Please help and plus, I don't know any Android techy language so please comment clearly so I can understand what to do to fix my Q88 Allwinner A13 Tablet. Thanks.
P.S I can boot into recovery using the BUTTONS. I have a POWER button and VOLUME ROCKER.
same problem
Hi,
I have the exact same problem with my allwinner 13 and the reason is Z4root.
The problem is that half of the memory is locked (1.96Gb) and it prevends installing apps. With ADB you can install things on an SD card but nothing works good and rebooting will give you factory settings.
The supplier will send me an SD card so I can flash the device.
If I have it I will come back to you (if it works).
How do I get in recovery mode with the buttons?

Hi, not sure if this is the right place, feel welcome to move it to the correct place.
I'm trying to find any firmware for a Tokio Tablet I bought recently, it's locked out with a passcode and been trying to root the thing so I can remove the passcode.
I've spent nearly 2 days just trying that with adb. I even tried superoneclick but as soon as adb is reset to root if freezes the tablet up or locks usb debugging mode up.
Is there something else I can try to do this or has anyone got firmware for it.
I even tried emailing SEGA but they said as it's discontinued they no longer provide the firmware anymore, to me that sounds rather silly in all honesty.
I've just about given up on it.
Can't even get a updating mode up either as it says "Unexpected Updater Mode!, Reboot using power button"
Hello, i am new here and i came in here for help.
It all started when i blindly flashed twrp v2.6.0.0 on my tablet, and now i regret that i have done that.
The problem is that it is stuck in a bootloader boot loop and the screen does not work at all when i am at the menu. The os is gone and i can't even go into download mode because the tablet does not have physical volume buttons.
The tablet is an estar mid 7818 mini (rebranded onda v818 mini).
Is there anything i can do? This is my last resort since i am tired of trying to find a solution to this rare problem.
edit:
The os is not gone, as it seems that the thing still has the default battery charging screen while being off, but it don't know anymore. I am no stranger to rooting and flashing, but that was mainly done on Samsung phones, which have much better support than some random chinese tablets.
I still need help, though :^(
Cheers if you read my mess.
edit v2:
I actually fixed it! So this is what i did:
1. found a thread on a different forumsuggesting that i should use iroot to download the drivers (because the device was not recognised by any software);
2. rommaster was installed with me not even knowing;
3. I pressed some buttons and the tablet rebooted to android (the ui was in chinese)'
And with my blind luck - i somehow fixed it.
Hopefully i will not end up in this mess again.
Cheers.
So I admit I am an idiot and did this to myself. I installed the latest FireOS OTA through TWRP then thought to keep TWRP I would install it before I rebooted. I know I probably should have read threads about keeping root and the horribleness of 5.6.0.1 but I did not. So I can boot into the OS and I can boot to bootloader but I have no recovery at all. Any one know how to recover from this? Found out the unbrick method I have used before does not work. Fastboot give me an error about locked hw.
Been working on this anyone know or have a fastboot zip or image. I am getting a errors trying to flash the amazon bin with fastboot.
I know I am the only one posting here. I read through a bunch of threads that seem to be people in the same issue. I have now managed to get it stuck in demo mode. I also cannot seem to accomplish much from fastboot because I get a locked hw error. Bought a couple for parts HD6s off ebay. So hopefully I can make something work and get at least one working tablet. This has really put a damper on trying to create a device tree to try and build cm12.
Closer to being a brick. Some how I managed to have root in adb and managed to wipe all. Which I guess really meant all. Now all I get is the amazon logo. No desktop. No adb. No way to get to fastboot.
So ebay tablets came in, bout a lot that had 2. The one was listed as a demo model, so a simple ;demo in the search and resell the device and viola fully working tablet. It still had 4.1.1 on it so a simple update to 4.5.3, Kingroot, and TWRP install and back on CM11. The second was "black screen" so I assumed bricked as it did not seem to turn on when plugged in, initially. Tried running through unbrick but nothing from ./reader.sh so assumed on newer FireOS that blocked that function. After setting the first up I was rearranging my stack on now 2, what I thought where, badly bricked devices. Hit the power button and booted to lock screen with 7% battery. So I now have an extra HD6 to mess with. Best part is I got both of them for $20 total.
