1. open a can of beer
2. backup pm and rpl of your 6151
3. flash with 6233 RM145, v05.10,21-12-06 (TAKE NOTE dONT use flash button USE DOWNGRADE INSTEAD)
4. after flash IMEI becomes 12345?54321? and garbage display but dont worry be happy phone is alive and can be detected by usb as 6233.
5. dismantle phone then prepare for TP as shown below cause most of the phone have resin glue and TP is not as easy as before.
6. unlock as usual using DSS uid, same as 6233
7. flash with the original RM200(6151)......phone display will be ok now but imei 12345?54321?
8. restore back up RPL (in my case PM field remain intact so no need to touch PM field)
9. SMILE again................. smile is as good as sex hehehe
