TWRP Recovery with UBIFS Support For Amlogic Nextbook Tablets (Support Thread)

[shaunmt]

ok. Have you been having problems with the power button?

Nope... which model and what type of problem?

March 2013, I think it might be the hardware, but if i dont use it for awhile then it works fine, but then soon it doesnt work right again.

Probably... I have several different models... Next8HI8G, Next8HD8G, Next7HD8G and two Next8P12. Power button works fine on all of them.

TRWP and Rooting...

Will TRWP be able to flash the Kyser root package on ANY Nextbook tablet?
If so, it seems to me this would be a stellar way to root your tablet.
Having the recovery boot from the external sd card is an awesome feature.
Is this feature unique to the AMLogic SoC?

The kyser_root package should work on ANY tablet that uses a UBIFS file system, which includes all of the Amlogic based Nextbooks and is definitely the easiest way to root all of those models. It does require a custom recovery though, as the stock recoveries can only install packages created by Nextbook.

Yes, booting from external SD card is a feature unique to the Amlogic SOC, and it is an awesome feature!

TWRP (recovery partition)

(non-amlogic nextbook tablet)
How would you flash TWRP to the recovery partition if you don't have root yet? Fastboot or ADB, maybe? Seems like a catch 22.

On a non-amlogic based device, getting recovery installed internally requires either root access, insecure ADB access, or a factory style flash tool that can flash the device in fastboot mode.

Would fastboot.exe from a pc cmd prompt work?

Probably... I'm just starting to work on non Amlogic devices since I picked up the new Nextbook NX785QC8G which is a RockChip RK3188 device. I rooted it with Kingo root. I can either DD the partitions from terminal or ADB or I can use the RKFlash tool with it, but the android SDK fastboot.exe would probably work also.

Also, be aware that many stock ROMs include a script in the that runs during boot, which checksums the recovery partition, and if it doesn't match the stock recovery checksum, it reinstalls the stock recovery before booting the Android system.

I noticed that TWRP renamed the backup recovery file in the /system dir to *.BAK on my Nextbook tablet.

Yeah, I just noticed that a few minutes as well... CWM did something similar, but it asked if you wanted it to or not, TWRP just does it without asking...

TWRP (stock rom backup with no root)

Will TRWP be able to make a complete backup of a system that is unrooted?
I ask because it could be useful on a brand new tablet for backing up the virgin stock rom.

TWRP works the same rooted or not... so yes, it will get the virgin stock system folder, however it never backs up the bootloader or logo partitions... it only backs up the boot image, recovery image, system, data and cache partitions. This is enough to make a ROM, but you need the bootloader to recover from a hard brick.
