1. Keep looking.
2. Keep asking.
Thanks to P3Droid and DJmatt. This is for Windows.
Here's what I did.
First-make absolutely certain that you have all the updated motorola droid bionic drivers for your version of Windows. Do a google search. you'll find them.
click here : Getting back to OTA upgrade path, retaining root, 901 installation
you're going to look for bionicpathsaver.zip. that has most of the things you need.
You should update the file that you download, however, with the following.
Name: bps fix.rar
Location: Free File Sharing Made Simple - MediaFire
Description: download these files, unzip, then copy all the files INTO your unzipped bionicpathsaver folder and overwrite what is there. Key file is runmebbb.bat.
in case you get a CDT error,
Location: MEGAUPLOAD - The leading online storage and file delivery service
Description: run it just like you do the runmebbb.bat
if at any point you get an error that says CDT error, use the cdt.bat file that you got and it fixes... make sure you read everything before you start step one tho! Then read it again. The Droid Forum link above is very helpful. Another extremely helpful link:
Bionic Path Saver 1-Click Method
Note unless you're registered user on MDW you can't access linkes shown thereon in order to get files. But the info/details are enlightening.
steps 1 - 4 literally are: 1) turn phone on, 2) connect usb, 3) set to charge only, 4) run the script.
Once you have the updated files copied into bionicpathsaver folder, usb connect your bionic, ensure it is set to charge only and the debugging is checked in menu-applications-development. Then click on the runmebbb.bat file.
Note the script will load both 593 AND 901 onto your SD card. The script will get you into android recovery to update to 593. You do NOT have to run it again to put 901 in if you don't want to.
Be very, very patient. This took about 90 minutes to fully execute. Do exactly what the script tells you. it will work. And you will be rooted again and be happy that you once again have a cool phone!
