Hi everyone ,
I have a Yarvik Tab460 with a AlLwinner A10 microprocessor.
And I removed the android and installed the berryboot bootloader because i wanted to try linux ons my tablet.
The linux worked and was running fine, but i wanted to chenge a few things and chenge some configs in the berryboot bootloader.
Now i guess u've bricked the bootloader and the tablet doesn't do anything anymore, won't even start up with a black screen, I'm unable to enter
recovery mode or even the factory hard reset mode.
When i connect the tablet to a PC it doesn't respond , does nothing , i've tried to use Fastboot and ADB but doesn't work either.
Then i read somewhere that i can try to let the battery go down, insead i opened up the tablet, with the nessesary procotions like antistatic tools en grounded body to prevent static electricity from destoying antything and removed the battery temorarly but it didn't change anything. When i opened up the tablet i saw that there were some serial( uart ) connections ( TX, RX and GND) , so would it be possible to install a new bootloader with these connections. or does anyone have another idea how i can get this tablet to work?
Thanks in advance and greetings Sammekevremde

Hello guys, i need your help.. I have an rk2918 tablet, its name is teclast p85a and i bricked it.. anyway i have installed a couple of roms but none of them worked(actually the 2nd one turned the screen into grey but that all)..anyway i plugged in my tablet but now my computer detects it as an Full AOSP rk29sdk device and not as RK29 device(which it was before i installed these roms). Now when i go to device manager in order to update the software and put rockusb.inf for windows 7-64 bit i get this error: Make sure you have selected the correct firmware for your operating system(windows 7-64bit) WHICH IS WHAT I DO..So now RKbatchtool doesnt recognize my tablet and i cant flash it with any rom... Does anyone know what to do?? Please i am completely lost.. Thanks in advance!!
Hi,
I've recently bought a second-hand polaroid mid1047pme01.112 tablet and the previous owner has made a big mess with its software. I'm trying to bring it back to life but I can't find a way.
Actually it can power up and show an image with Polaroid written on it and it won't do anything else. I can't access the recovery mode so I don't know what I can do to install a working CWM (I think I already found a working copy of it, but I don't know how to install).
If the tablet is connected to a PC it doesn't react (the PC doesn't show nothing, even the driver installation procedure).
May you know which are the steps I should follow?
Hi guys,
I just bought two brandnew Cube U27GT S (MTK 8127) tablets and tried to install a custom rom. Unfortunately the tab hard bricked while trying to flash it with SPFT. Now I can´t turn on the tab anymore - all black. I even can´t open the recovery mode and Win 7 doesn´t found the tab anymore, it shows unknown device in the device manager!?
Meanwhile I deinstalled all MTK drivers with usbdeview and installed them again with the help of the second tab. But it has no effect of the damaged one it´s still an unkown device.
Maybe anyone has an idea how to unbrick it? Would be great to get any help! :crying:
No hope anymore?
I have the same problem can only get into recovery, factory reset does seem to do anything still hangs on boot, looks like I need to update via sdcard?
Hello. I'll try to explain my problem because I really need some help.
A few days ago, I was normally using my Tablet ECS TR10RS1 Intel®.... I turned it off, went to sleep and the next day when I was going to use it again, the OS didn't start, so I tried and tried until I found a forum where they led me to restore a backup file because the original firmware/rom wasn't still available.... publicly. I tried that, but in the process, I accessed the EFI Shell... That wasn't trouble at all, I just plugged the keyboard and typed "exit", and then it let me to the BIOS... And that's when my real problem began: I restored the factory setting default... and it involves "disabling USB ports".... Now, AGAIN, I'm stuck on EFI Shell. But this time, I can not type "exit" since the keyboard is not recognized by the Tablet.
Then I pressed Vol UP + Power ON and I get access to another menu "DNX".... And that's what brings me here to your forum:
I was briefly reading that one of your members managed to flash the BIOS via DNX, so I was wondering if you guys could help me do that to my tablet because I'm not planning to have a really expensive paper holder.
Thanks in advance.
Jinky.
Not sure about your case. But as your tablet use clovertrail chip like my zenfone 5 n fonepad7 170CG, then there's some methods to unbrick like via fastboot, flashtool, or intel factory flash tool... all of above are required a valid firmware, at least a IFWI package then intel FFT can unbrick anyway. So try to find your need, as i tried to help u to find it, but most of webpages use spanish, then i didn't understand anything

Hi all,
Hoping someone might have some knowledge on this Chinese cheap build tablet.
Its an iRulu eXpro X1, model X10. Inside is the Allwinner A83T with 16Gb Rom and 1 Gb RAM.
This was previously with my daughter but we just upgraded her to a Sumsung Tab A, so I thought I'd play with the iRulu (bad mistake lol).
The iRulu was still running kitkat so I rooted it (Kingo Root works fine in anyone else is trying), attempted to install CWM and TWRP. Both failed, every attempt through adb / fastboot gave bootloader: secure mode fail error.
So I them decided to flash the new rom from iRulu's website - using PhoenixUSB.
All was going well, the tablet went into download mode (hold Esc button, plug USB cable in and press power button 10 times in rapid succession.) and the firmware started to download. At 80% PhoneixUSB threw a boot(0) error and stopped.
After this the tablet will not start (nothing on display) nor even show the charging icon on the screen! It does however still enter the download mode so I can try other images. So far I have tried 5 different images (including darkglow10.1_android5.1.img, A83T_N102_N1021L1BC_20151123.img) however all of then error when writing to the bootloader. I have also tried PhoenixCard to write an image in Startup mode - this gave nothing Live Suite makes no difference either, using the images I have.
Unfortunately the serial number has worn off the device so I cant be sure of the exact firmware from iRulu website to install. (I've mailed them for what its worth).
I have opened the device and the pcb is marked INET-N102-REV01 and Zeng-gc2014-12-22. Google has some stuff on it but nothing I understood
Does anyone have any thoughts? I'm concerned that the bootloader is locked / corrupt in some fashion which is stopping the download.
thanks
update: using the x1081 firmware from iRulu and PhoneixCard I have restore functionality. The device thinks its an expro x2 plus and it doesnt recognise the SD card slot (tried multiple cards) but other than that it seems okay
Will try to figure the correct firmware thou - anyone?
thanks
Having the same issue
Hello, I am having the same problems with that tablet, got it from this girl I'm seeing. It was freezing whenever it connected to the internet, I assume was a ROM issue, i flashed an incorrect recovery on it after getting frustrated. Can you please help?
