Heyo! .. This tutorial is for the people who are confused flashing the K800 to K810 properly. You can reply to the thread regarding any problems with this tutorial.
1st of all, I recommend starting all over again and I ALSO recommend using R8BF003 Firmware.
F8B003 MAIN - 4shared.com - online file sharing and storage - download K810_R8BF003_MAIN_GENERIC_SM_RED53.mbn
F8B003 FILESYSTEM - 4shared.com - online file sharing and storage - download K810_R8BF003_FS_TELEF_GEN_RED53.fbn
CUSTOM FILE - ( Do not forget to add this to your phone ) - 4shared.com - online file sharing and storage - download K810i_custom_pack_(finalization_files).zip
Installing -
1. Open up SETool.
2. Select Phone Type : K800
3. In the files box, add K810_R8BF003_FS_TELEF_GEN_RED53.fbn and K810_R8BF003_MAIN_GENERIC_SM_RED53.mbn . ( Any order, doesn't matter )
4. In the Misc files option, click on the '...' button and add K810i_custom_pack_(finalization_files).zip .
5. Click on Flash on the right side corner under Unlock/Repair.
It should be something like this :-
Do not unplug the phone in between flashing.
Do not unplug it until SEtool shows the Elapsed Time.
:D :D HAPPY HAPPY FLASHING :D :D
