Downgraded to 2.17...now phone soft-resets frequently

[Cheatachu72]

So I tried out 3.16, and DCD's and No2Chems roms and enjoyed them all but they were too buggy for my likes.

I used the titan relocker and then flashed back to 2.17, and now the phone soft-reboots like mad.

Sometimes it will be fine for an hour, then the screen goes black and it soft-resets. Sometimes it will soft-reset 3-5 times before the phone boots up. I have hard-reset 3 times now, and with absolutely no programs installed i get the soft-reset at random times, the phone will be in my pocket and i feel it vibrate, then hear the boot music

I flashed the 2.17 rom from the sprint page, am using prl 60611, it says radio is 1.47.01.

From my reading this sounds like a radio problem (?) Any suggestions on how i should troubleshoot this? Downgrade radio to 1.40?

EDIT: I should add I have SPL 1.07

Before I flashed the 3.16 and derivatives, I never saw this problem. Thanks in advance for the assistance
