i take no credit for any of this. just the consolidation. There have already been multiple threads detailing how to upgrade to 901 and retain root, however lots of people are still running into issues. I hope to clear up all of them with this post if possible. read the ENTIRE OP BEFORE attempting this. First off if you have the released root script with multiple options to root, forever root, etc. DELETE THIS FROM YOUR COMPUTER. Not screaming, just emphasizing. :happy3: It does not root 5.5.893. dhacker has already stated its meant for the 5.7.893 leaked update, and you will run into issues with no data connection if you try to restore your bionic with this script after starting the pathsaver script because it wipes your data. thats a big no no while doing this. Here are all the files that you will possibly need. i recommend saving them all, but you shouldnt need all of them since some are files you will need in the event of a brick. Pathsaver with runmebbb.bat from the OP in this thread: http://www.droidforums.net/forum/th...atible-kin3xt-v1-0-p3s-one-click-upgrade.html radio.zip: MEGAUPLOAD - The leading online storage and file delivery service cdt/invalid CG fix: http://www.megaupload.com/?d=K8SDG7VY cdt/invalid CG fix 2 (download BOTH): http://www.droidforums.net/forum/dr...package-zip-ro-build-product.html#post1948188 step 1. have phone booted with debugging on, charge only, and allow install from unknown sources (just to be cautious) run script and do not interrupt. it flashes the boot.img very last after rooting and forever rooting and you can not update with out the restoration of that file. step 2. once the script is finished it will automatically close and should you should see a little android with an exclamation point. this is normal. hold volume up and volume down simultaneously to enter stock recovery. navigate to "install update from sd card" and find and apply the 893 update. then in the same recovery session again navigate to "install update from sd card" and find and install the 901 update. congratulations you are now on 901 rooted. Troubleshoot its a quick process when everything goes smooth but i find it rarely does for most. if script hangs at any point, close the script, stay in or boot into fastboot and run it again. if it continues to fail, stay in fastboot (watch you battery because if to low it wont flash. i found my phone still charged while in fastboot when connected to a wall outlet, but not a computer) redownload the script and run again. cdt.bin/invalid CG error in fastboot: this happens after applying the 893 update using the pathsaver script after already updating to 901 once, leave the phone alone and connected to your computer. unzip the fixcdt.zip you downloaded and run it. you should be able to hit the power button and it start up. if this does not happen after running the fixcdt script, follow the instructions from the OP where you downloaded the cdt/invalid CG fix 2. you will need to rerun the pathsaver script and start the process over after you do this. no data connection: this is due to a data wipe before the pathsaver script was finished. boot into stock recovery and flash the radio.zip. its best to rerun the pathsaver script after this due the boot.img probably not being flashed. get to 901 and lose root: run the runmebbb.bat again. thats all i can think of at the moment. this should be somewhat fool proof but we all know better. if any of you have anything you feel needs to be added to this to make the process easier, have any questions, run into any issues not stated here, and/or if there is an issue with a link please let me know below. trying to keep everything consolidated in one thread so people dont have to search so vigorously D.W.
