First of all thanks to the forum members for giving details on flashing, unlocking that a novice like me learn few things.
I tried unlocking W810i with SEtool lite 1.0 updated to 1.1 but couldnt succeed
I followed the following steps -
Using Xs++, found the DB and firmware
Downloaded generic firmware
Using SEtoollite 'Read GDFS' for backup
Using patch generator (thanks to simox) generated the vkp
Now selected SEtool 1.1. Selected the mbn, fbn files
Also selected vkp in misc..button and Flashed it successfull
PAtched it with the Tool 'write script'
Now while i tried by cliking 'unlock' button, Tool just identifies the phone but didnt unlock
Not sure where I went wrong. Please advise
Edit: I used W810_R4EA031_MAIN_GENERIC_HN_RED49.mbn ; W810_R4EA031_FS_EUROPE_2_RED49.fbn for flashing.
