Ok guys! Here's a little quick(and obviously initial) build I made. Note this is an untested version. I am planning to test this later but just sharing this to you guys in case anybody is interested. Plus test from other devices other than mine would really be a big help and should shorten my development time.
(Please use the sendspace link as much as possible. This would save me bandwidth from my dropbox account
they might block my public link if I consume all my bandwidth)
- Direct link for ROM only
Now I am using Doomlord's ramdisk image for Arc on this build since there's no ramdisk for pro yet. I just tweaked it a little for it to be compatible with Pro. Recovery is also there you could initiate it by using volume down button. This build is suppose to work unless I messed/missed something. If so then sorry
Step by step installation
1. Copy the updateable zip
to your sdcard.
2. Download and flash the kernel
through fastboot by executing
fastboot flash boot <kernel image here>
3. Turn on Phone and reboot into recovery.
4. Flash the updateable zip package I provided.
5. Clear cache, dalvik cache & userdata.
5. reboot into system.
Note: Before doing any of the steps above make sure you created a backup of your ROM using CWM. In case phone doesn't boot just reflash the kernel you use/Xperia Pro Ultima Kernel & restore the backup you just made(That way you'll be back to good old gingerbread).
