***Motorola Droid X Rooting Guide***
Thanks for the tip, Im looking further into this.
The ACS Alaska "Droid X - milestone X" came factory with froyo 2.2.2, and we just got this OTA update to GB, the numbers I posted above are exactly what is listed in the "about phone" data.
System Version: 4.5.604.MB809.ACG.en.US
Android Version: 2.3.5
Baseband: BP_C_02.12.00R
Kernel: 2.6.32.9-geadffa3mcbk83@il93lnxdroid08 #1
Build Number: 4.5.1_57_MX2-34
With the old 2.2.2 Froyo, I had root access with a SU app. I left the phone as was rooted during the OTA, because the OTA began downloading automatically and I didnt know it. When it was done, I still have the SU app, but it does not work, and none of my SU apps function either.
I had used the PMRT process for the Droid3 flawlessly before, and I mean it was so EASY it wasnt even funny. My kids could do it. Now it gets to step 3 of 3, and pops an ERROR: "the adb could not be granted root access via the local.prop method" try again from the start, check your version of gingerbread, hopefully you do not have a version where this exploit was fixed..............????????????
Going here, gonna try this, theres a new PMRT v1.07
