Please connect me with ANYONE who can help me figure out how to wipe a tablet to get it back to the original start-up. It's a Vantron 5081-G Tablet running Android 7.1.0 with a RK/MK 3368 Rockchip with a Rockchip 808-H bus chip and a SanDisk SDINBDA4 32G that has a management partition I don't know which to reset if any and how to go about doing it without a pc. I have a USB jumper or I'm ok with doing the short to ground method if I only knew how. Everyone's referring me to the Rockchip datasheet, which I have but it tells me nothing about getting it off of the optional consumer boot 11 add-on and back to the factory Rockchip setup. Please help me. If you don't have this information then I'm sure you know someone who would. Thank you for your time and consideration.

BRICKED 7inch Irola Tablet...PLEASE HELP
I am in DIRE need of some help with my tablet. I received this irola dx752 tablet bricked and cannot fix it for the life of me. I am able to hold power and volume up and get into recovery system version 4.2.01. I Have tried a factory reset and a wipe system cache and the tablet just reboots to the green robot with and exclamation mark. If I press volume up, it brings me back to the system recovery. Now i am not very versed in ADB but I tried to sideload just about every firmware I could find for an a13 allwinner a8 cortex 7inch tablet, since the irola website has taken down its firmware. Also, fastboot will not work on this tablet whatsoever (it just says waiting for device) when i enter any command. I have never seen this tablet boot into a rom of any kind and therefore cannot tell if USB Debugging was ever enabled. I also Have tried different drivers but the one that seem to hold is the Android ADB Interface. CAN ANYONE PLEASE GIVE ME SOME SUGGESTIONS OR SOME HELP? It would be greatly appreciated. Thank you.
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.

Please post how you fix this problem.I have the same issue and maybe others are looking for the fix too.
Thank you
I have come into possession of a Polaroid P900 tablet which says it is Powered by Android, however, when turned on it never progresses past the boot screen. The model number on the back of the tablet is P900 and the build number is BN01.01.006.076.01.
The battery seems to charge fine and I can boot the tablet into recovery mode, in recovery mode the model number, or perhaps firmware revision number, is P900_20141216. I have tried the factory reset option to no avail.
The bizarre thing is I can't seem to find any information on this tablet online, apart from a copy of the really basic Quick Start Guide on the official website. There seem to be no firmware images or Android updates I could attempt to flash the tablet with to try to fix this boot issue.
Does anyone know of any resources I can use to fix this booting issue?
Alternately, if this is not an appropriate forum, does anyone know any other resources for hacking these tablets?
This is the first Android device ever in my possession so I am at a loss as to where to go or what to do at this point!
Thanks for any advice or suggestions you may be able to provide!
Hello,
First of all thanks for all these amazing useful information of this forum.
Well, I will try to explain what is the problem, sorry about my English.
I am trying to recover a TV Dongle or stick, it hasn't got a VOL + or VOL -, so I think that I will need to touch the different Pins that the NAND has to boot it in recovery or a known device for the RK Batch Tool.
The CPU is the RK3028A
The NAND chip is the 29f64g08cbaba
The GPU is MALI-400
Has anyone any idea which are the PINS that I have to touch to recover this TV Dongle???
Thanks for any help, it will be appreciated.

This started when you mounted system? Or it started when you mounted system and tried to modify something?

it actually started when i mounted system. no modifying.
ok so i got the firmware from the company that sold me the tablet. is there a way to convert the img file so i can use it with phoenix card?
no software will work for me because the micro usb connector is loose and it won't even stay connected long enough for my pc to recognize it.
Hey.
Please send me a file that I could download and firmware my device Yuntab B102.
