Hmm if you have NTT DoCo leftovers, then this only suggests that you didn't wipe system partition properly at the end, because NTT DoComo apps are all system apps...

To do that, power off your phone. Then power it on again. After the vibrate and the green LED turns on, hold Volume Up (LED will turn violet)
[/LIST]

once the screen is black how do you see to do the next three steps.

If anything goes wrong steps 1-21 how do you get your phone working.

Also before rooting you say Back up your phone because it will be deleted. How do you back it up?

Also how do you reboot in step 17?

How do you factory reset?

Hi guys! Just a quick question. I noticed in init.rc that Trim Area uses 2 partitions. It's mmcblk0p1 and mmcblk0p16. I know mmcblk0p1 is the TA partition but I'm worried about mmcblk0p16 do you think we should also backup that? I don't know but maybe sony added a new partition which might block restoring DRM keys on Z1 Compact? Anybody already tried backup, unlock and restore TA partition and confirm that DRM keys and bootloader status restored?

Just follow the steps when your screen is black and plug in the usb cable.
You can flash your stock rom again in flashtool if anything goes wrong. Or just start again from step 1.
It means backup your data (internal) and should just be a notice that your data will be wiped.
You don't have to reboot in step 17 it says
Quote:

Now format /system (located under Mounts & Storage) (Important: Do NOT reboot until advised so or you will have to start again)

And factory reset is done in recovery menu (it's called "wipe data/factory reset")

Bootloader is locked again, however I don't know about DRM keys. You might want to ask the dev of TA backup about this second partition.

If you run
Code:
ls -l /dev/block/platform/msm_sdcc.1/by-name
it shows as FOTAkernel.

Yeah I already saw that. Hence why I asked about the DRM keys... Oh well I guess I'll just back it up in case. No harm in doing anyways.

I had that problem too! I think it is normal, so perhaps this additional step should be added to the end?
(was getting really p*ssed off with that stupid sheep roaming all over the place, so thanks for the solution! )
