I’ve created a small update package to root the factory C71 ICS release. I hope it will be useful for others as well.
This package is provided as-is. It worked for me, but I take no responsibility whatsoever on it’s effects on your device!
IT MAY AS WELL BRICK YOUR DEVICE, OR YOU MIGHT LOOSE ALL YOUR DATA!
Do not use it for any other ROM but the official ZT280_E7_1n_C71_Android4.0_0104_V1.2.rar! It might work, or screw you up
(!!! You’ve been warned !!!)
This update will install the su binaries and SuperUser application on your
This is NOT a rom, it’s only a supplement to root the ICS. If your device doesn’t use the ZT280_E7_1n_C71_Android4.0_0104_V1.2.rar ROM, you must install that separately.
This update is written so the root can be applied AFTER the ROM upgrade, in order to add the root capability without screwing up the actual data and applications already on the tablet.
- MAKE SURE YOUR SD CARD DOES NOT CONTAIN THE “zt-update” FOLDER. If it does just remove it.
- Extract the contents of this archive in the root of your SD card.
- Move the kernel and ramdisk for your device from the appropiate folder (1n or 1f) to the zt-update folder. If you want to use it with any other ROM than the ZT280_E7_1n_C71_Android4.0_0104_V1.2.rar YOU MUST use the kernel and the ramdisk from the newer version. (see disclaimer!)
- Insert card and reboot the tablet keeping the Vol- pressed (ie. do a standard update)
li>Update will finish with an error, that it cannot find the system, but NO WORRIES
! this issue is fixed in the updated version
- Reboot and enjoy root!
Licencing and price
