Well, first post is confusing... Especially this string:
First you must use MotoWPNoMo, if you haven't then you will need to. Use RockMyMoto to gain root, then use MotoWPNoMo, and then restore to the 4.2.2 Camera update.
Right now I have 4.2.2 with camera update (12.15.15). no root, pure stock. Do I really need to rollback to the stock 4.2.2 in order to get root and make it survive the 4.4 update?
If I got it right - no, as soon as RockMyMoto works on 4.2.2 with camera update (12.15.15). So I have to do is:
1) Follow instructions on RockMyMoto, get root
2) Follow instructions on MotoWPNoMo to get permanent write protection off
3) Follow instructions at the first message of this thread to get 4.4 installed and preserve root
right? No any rollbacks required, etc.
Thank you in advance.
