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!!

I believe I've USB bricked my Onda VI40 v3 16gb, I can't access the internal sd card and the device wont communicate with my pc when its connected by usb.
I have CWM Recovery installed and can access and flash roms from it but pretty much all of the guides to unbrick the usb require fastboot and I cant for the life of my work out how to get it on the Vi40.
Can anyone shed some light on how to access fastboot on the Vi40 or any other suggestions for unbricking the usb.
I have flashed multiple different roms on to the device in an attempt to fix it with no luck.
I can access an emulated terminal screen on the tablet when booted if thats of any help.
I have also tried the image_flash and mtd0.img fix but I don't know the devices CID so that doesn't work.
Thanks in advance.
Go back to the original rom
check what version is your onda vi40 by checking the serial numbers at the back (ex Xxxv3xxx) means its a v3.
then go to onda.cn and look for your version firmware.
you nay have to use Google translate.
now once you have downloaded the correct firmware version pls remember to rename the image file which is in Chinese to any English name. hmmm on second thought go to slatedroid.com and search for the onda forums they have a detailed English guide to help you.
don't panic, the same thing happened to me on my onda vi10 elite but my mistake was flashing a custom firmware. just like you I lost some partitions but when I flashed the original 4.03 v1.1 firmware and selected format the tablet is fine again.
Vi40 16gb v3 - can you flash using osx?
Hi all, my vi40 was connected to my MacBook pro the other night ttransfer some mp3s and I think I may have turned Off USB mode on the tablet before unmounting.
Now every time I try to install an app I get the "no space left" type message altjough there's about 15gb of space left.
Almost like permissions won't allow write
Downloading from play store starts but never completes
I'm thinking may be best to reflash the firmware?
I only have macs though.
If I have a mate with a vi40 same model would I be able to clone his onto my tablet using mac carbon copy cloner app maybe?
Cheers
Chris

Ps every time I turn off and reboot it reverts to Chinese too
Easy, run BootCamp on your Mac, I have bootcamp on two of my macs and they run windows 7 pretty nicely

Hi ,
Have you tried to reflash with livesuite ? if not then do it with a stock rom and reflash cwm from there no ? remember to enable "usb mode" by pressing menu key then plugging the tablet to the pc ( the menu key act as a temporizer for the tablet to be detected in that mode afaik)

Intex RK2918 based tab
I'm having an INTEX iTab. How did you update the tab? If it is an official update you'll have to take the tab to INTEX Service Center. There's no Intex PC Suite available at present,so you can't update it over internet. But, you can flash new ROMs to the tab. Refer to INTEX iTab thread. It may contain something useful. Or ask OMA if you want to flash custom ROMs.
Hi guys, after installing chainfire3d and reboot the device it win't start any more, it stop on teclast logo, rockchip flash tool don't recognize the device that in windows is seen as adb device..for some strange reason if i look at the device details it will be recognized as an htc?? I can start in recovery mode (the one with the little android ko with a red "!")
I really don't know what to do now.. someone with a brillant idea and some more experience than me can help in a flash with some other tool? or if exist an emergency flash from sd..
Thank you!!

Hello, how did you solve it? Please any help will do.
Hi,
I bought a Nextbook Premium 8 SE, model: "next8d12f", the device contains core AML8726-MX.
I tested different procedures such as root device but managed to me only to load the firmware from Prestigio 5580c here but could not turn on wifi, so I flash firmware Next8HD8G but a here too wifi did not work and still poorly functioning motion sensor.
Finally, after the last restart from recovery device not start and now does not turn on at all, just a black screen and end.
Only what indications are there any hope, its that, when I plug the USB cable to the PC the Device Manager recognizable M6-chip or an unknown device .... I downloaded many drivers for android_winusb, rockusb, adb etc. but do not know which one to choose, when the device will not boot or image flashes
Can you please advise how to put this device to the original state, I do not know how to end and that the dead / frozen up of devices, doing so in advance thank you very much for any help ... thanks
P.S. Sorry for my english, this post was created with the assistance of Google Translator
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?
