The symptom is that the phone will boot witht eh Samsung boot animation, I will see the Clockworkmod icon at the bottom, some Clockworkmod version information, then the phone will reboot. This will happen presumably indefinitely. I have watched it do it 3 times in a row and then pulled the battery. Post Philz, I get Android tablet icons instead of Clockworkmod icon and version info.
I loaded Whompasaurus http://forum.xda-developers.com/show....php?t=2039564 to my phone yesterday and I was about to load Venom http://forum.xda-developers.com/show....php?t=2121063 to my phone this morning (I had just copied it to the SD card). I told the phone to reboot into recovery by pressing the power button and selecting the option "reboot, recovery". The phone is now stuck rebooting attempting to enter recover and failing, or so it appears. I upgraded the Clockworkmod version to 184.108.40.206 yesterday, and that did act a little weird in my opinion, but since I had never done that before, I wasn't sure what to expect.
When I told it to upgrade in the Clockworkmod app, the phone powered off and I had to remove the battery to turn it back on. I booted to recovery and it said it was now at 220.127.116.11, so I booted normally. Back in the app it said it was 5.something. I kept poking around and it eventually asked for root access, which it hadn't before, and when I told it to upgrade the recovery this time, it actually rebotted the phone rather than turn it off.
I reflashed the CWM 18.104.22.168 recovery with Heimdall per these instructions (why aren't there proper instructions for Odin?!?!?! ermahgerd!!) via this link http://wiki.cyanogenmod.org/w/Install_CM_for_l900
That was successful but did not affect the symptoms.
I upgraded to Philz recovery thinking maybe I had to use a different recovery to reset the "boot to recovery" flag. I used this file and Odin, after resetting the Samsung driver: http://goo.im/devs/philz_touch/CWM_A...6-l900.tar.md5
The process was successful, but did not change the symptoms. Instead of seeing a Clockworkmod icon and version info at the bottom, I see what looks like android icons at the bottom, and then the phone reboots.
What can I do to fix my phone? I can boot to downloader mode fine. I would prefer to use Odin, but it seems I have Heimdall set up and working too.
