Hi, I sent my phone to HTC for RMA. It is already back with mainboard and display replaced and statement that original MB was burnt out. It comes with Gingerbread 2.3.3 installed. Now I'm trying to downgrade to Froyo and root it, but I hava a problem with installing Froyo PC10IMG.zip image. It flashes successfully without any error but after the reboot there is still original Gingerbread 2.3.3 up.
Details about Gb:
system version: 2.3.3
sense version: 2.1
baseband version: 126.96.36.199U_26.10.04.03_M

2.42.405.4 CL 192788 release-keys
Any ideas how to downgrade?
