I am sure this has been covered.

well i suggest you go downgrade to .886 by using this guide and downloading all the files: http://droidmodderx.com/bionic/p3droids-bionic-path-saver-1-click-restore-bionic-to-upgrade-path/
then you need to maintain root with forever root method: http://droidmodderx.com/bionic/maintain-root-through-any-update-bionic-with-forever-root/
the updating to .901 and you should maintain root the flash whatever rom you want


EDIT: if you need files like root browser or the .901 file so you can flash in stock restore screen ill upload then upon request

 

I had to run the path saver 1 click program twice. First time upgraded me to 901 unrooted, second time restored my root. However, I did have to uninstall Superuser and reinstall it from the market after regaining root.

 

Has anyone seen great improvement in their phone (for any reason) updating to 901? I had a data issue before the 875 update but that took care of everything. I'm not going to mess with the 901 because my phone is working excellent now. I'm just curious what the 901 was supposed to bring to the table?

use 1 click return path to return to stock then on stock update to .886 and use this 1-click_exploit.zip to root your phone (it uses an updated way to root your phone for .886 then use that video tutorial to forever root method your file so then you can flash this file 901.zip through the droid bionic stock recovery ( hold down volume button and power button) you should maintain root if you get a cdt error use this to fix it 901.zip



edit: make sure the .901 zip file is in the internal storage not the sd card storage

 

Thats odd. Maybe we're referring to different pathsavers. The one I used had forever root built in.

For the OP, make sure you have the latest motorola drivers installed, phone set to charge only, usb debugging enable, etc.

 

I believe that means you need the latest Motorola drivers for your phone installed onto your pc

 

It does but for some people it doesn't work so it's better to do.it manuely to insure it goes threw and there is no root for .901 so you have too too root and use forever root manuely on .886 to pass onto .901 by flashing with stock recovery that's what I did and it worked for me
