[RECOVERY] TeamWin Recovery Project 2.8.7.0

[PJBrs]

This is TeamWin Recovery Project version 2.8.7.0 for Lenovo Ideatab A2109.

twrp-recovery-2.8.7.0-20160303.img (MD5: bc56af770828092271fd92d11021bbcc)

Sources are in the cm-12.1-twrp branch of my device tree on github

This is a very nice recovery with more functionality than cwm. Note that cwm backups appear to be incompatible with twrp!

To install, reboot to fastboot and use fastboot to flash the recovery image. On Linux:

fastboot -i 0x17ef flash recovery twrp-recovery-2.8.7.0-20160303.img

Basics for installation (how to boot to fastboot, etc.) are over here:

I've tested the usual functionality myself (backup, restore, adb sideload, installing zips) and a few other bits and all appears to work fine.

Thanks for testing! I'm a bit puzzled, I myself am using twrp with an sdcard. If you open one of the mount, install, backup or restore menus, each should have a large button somewhere saying something like Storage: Internal storage. If you tap that button, it will offer you the choices of internal storage, sdcard or USB stick. Please check.

Yes, I find this button, but I can't change to sdcard, only internal storage.

I'm sorry, I can't replicate this. Did you first mount it? Try to open a shell with adb and issue

mount

and perhaps

dmesg

just to see if anything stands out.

has anyone else had a file system problem after changing from cwm to twrp? I had an e failed to mount preload problem. Fought it for a day and switched back to cwm 6.0.5.1 and the problem seems to have corrected itself. (or so it seems for now)

There's a message about a filesystem error always, but it's harmless (I messed up the fstab in that one). So, if that's the same error you're seeing, then you should have no problem with twrp.

Trying to produce a new build of this for the 3.4 kernel/CM14.1. Going in pretty much blind and learning the entire android build process as I go. I've got a succesful recovery.img being built, but fastboot is failing with `remote InvalidSize)`. Anybody got any idea what this is about, or anything else I'd need to do to update the recovery?

Hi, I haven't used 3.4 myself for twrp, since the resulting kernel was too big. Instead of flashing your recovery, you can also just boot it (sth. like fastboot -i 0x17ef boot recovery.img), then you can check. However, I do have a new recovery now, I'll post it later.

I tried to flash the twrp-recovery-2.8.7.0-20160303.img on the A2109 but when I reboot it remains stuck on "Booting Android Recovery ..."
