It started out so simply. My XT926 running 4.1.2 kept bugging me to run the OTA to 4.4.2 KitKat. Since the bluetooth has become increasingly unpredictable in the past few months--I decided to bite. Phone has been rooted since ICS nearly two years ago. Never a tap of trouble with OTA in the past. So this morning, I open up Titanium and unfreeze all of the bloat, clear the caches, and do a full backup. Check. Turn off debugging. That was probably my second mistake after deciding to do the update. Temp unroot through Voodoo, and reboot. Check. At the OTA screen, tell it to do the deed. Download competes, goes into red dot part of boot--and stays there for 45 minutes. After a bit over an hour, I tried a soft reboot. No response from the buttons. Split the case and disconnected the battery ribbon. Goes into boot, and ends up on the pitiful dead droid laying on his back. Loops back every minute into the full red dot reboot. It will boot into the first white letter screen--but nothing of any import happens with Fastboot. Menu comes up at the dead droid--but will only clear the cache and do a sideload from the SD card with the recovery tools. Tried that with the blur zip that is the most current--says its already loaded and aborts. Same thing with adb. Incidentally, this is the only mode that adb will connect--and it has to be initiated on the phone first. No other commands work to exit this mode--nor enter another. Rebooting out of sideload adb cannot find the device--on any port--via the previously identified device name. RSD Lite 6.1.4 has never been able to show the device. I downloaded the full 4.1.2 SBE (the last version, VRZ_XT926_9.8.1Q-94-1_CFC.xml.zip) ) and edited out the XML file getvar line. But it will not connect. Too tired to go up a version on the RSD tonight. Every suggestion available has been done. Three kinds of drivers. No joy. I simply cannot get adb to connect any way but sideload. Fastboot is not working correctly. Damned thing keeps looping through boot to dead droids and back again. Any suggestions?
