Hi. I stupidly forgot that I was rooted and applied an OTA update (OTA_Bravo_HTC_WWE_1.21.405.2-1.15.405.4_release_P4ohim1mtp6zggcyon). I'm now stuck in a loop where it won't get past the initial HTC bootscreen. I can get to the bootloader (hboot 0.93), but if I choose recovery I get to the 'stock' recovery screen. trying to update to another rom results in 'signature verification error'. I've tried loading the zip from this thread: http://androidforums.com/htc-desire/177907-froyo-2-09-405-8-update-windows-not-required.html but it fails as my 'main version is older'. Any ideas on how I can get any working rom going?
