Hello
I am newbie

I have asus memopad 8, someone installed Chairfire 3d on my tablet, so It can't boot anymore, I only saw the loading asus logo.
My tablet is rooted, I tried to install stock rom by using default recovery (Power + Vol up) but: installation aborted.

does fastboot works on your device??

I plugged cable to my laptop,
I held vol - and power, I installed fastboot driver, But when I opened Minimal ADB and Fastboot, then I typed:
adb shell -> error: device not found
abb devices -> no deivces

I held power and vol+, and Minimal ADB and Fastboot:
adb shell -> error: closed
adb devices -> [serial] siteload

Yeah: 0123456789 fastboot
EDIT: And I don't know why my tablet sometime disconnects, I have to reconnect the usb cable and press Vol - and Power

ya now your device is in fastboot mode.. now copy your boot.img , system.img and recovery.img to folder where minimal adb and fastboot is situated then type

fastboot flash boot boot.img

fastboot flash recovery recovery.img

fastboot flash system system.img

fastboot reboot

thats all :good:

Try these steps


My friend then try installing cwm recovery to your device, follow these steps to install

1. Download CWM recovery for ASUS memopad 8 here.
2. Copy the downloaded recovery to location of minimal ADB and fastboot.
3. Rename the recovery to recovery.img.
4. Boot your device into fastboot mode.
5. Type fastboot flash recovery recovery.img
6. Type fastboot flash misc misc_reboot-recovery.img
7. Type fastboot reboot recovery
8. You should be on CWM based recovery if you did the steps correctly.

In CWM recovery :

1. Go to wipe factory data using volume rockers and perform wipe data
2. Go to wipe cache partition and wipe it
3. Go to advanced and wipe dalvik cache
4. Go back and reboot your device.
5. If your device doesnt boot still then again boot into CWM and choose zip from sd card and flash the stock rom.zip placed in root of your SD.
6. After flashing successfully initial boot will take sometime so wait patiently.
7. Thats all you have recovered your device :good: :D

This is because your bootloader is locked do this to unlock and try

Type fastboot oem unlock hit enter
Type flash recovery recovery.img
Continue with above mentioned steps....
