You have the following issue to solve:
- don't use firmware files that don't match one another, like mixing R4EA031 and R4ED001 versions.
- in order to flash the phone the right way you need the same firmware versions
- did you verified the phone's CID version?
- are you sure it is CID49?
IF YOUR W810 is CID49, use the following firmware files:
- W810_R4DB005_MAIN_GENERIC_HN_RED49
- W810_R4DB005_FS_S_E_EUROPE_RED49
- W810_CDA102555_3_R2A_Generic_S_E_EUROPE
Remember the following rules:
- MAIN and FS files version must be the same
- FS and CDA language zone must be the same
The firmware version pointed by be is an earlier one, but it will help you get to the end of the road.
First, flash your W810 with R4DB005 MAIN FS and CDA.
Next, update your firmware by Sony Ericsson Update Service.
Take a friendly advice and FLASH your W810 with SETool2Lite. I think it's a lot stable and safer, not to mention it's easy to use for a newbie.
AND FOR THE MOMENT DO NOT USE OTHER CUSTOM W810 CAMDRIVERS. USE ONLY THE ORIGINAL ONES BECAUSE THE CUSTOM DRIVERS ARE NOT WELL OPTIMIZED YET.
GOOD LUCK! BE WELL!
