Thanx mate but it is FINAL - NOT POSSIBLE !
I have tried, the sim cards are diferent, the chip is diferent.
Proboly is possile with 2 boxes of same tip, buit like this :dm500hd vs dm800sehd is NOT POSSIBLE !
Friend, 100% the chip is diferent !DM500HD not recognize chip of DM800seHD and DM800seHD not recognize chip of DM500HD !!!!
"2error" - is on display !!!!
Not allow me to flash SSL, I have no possabilety :
I have used a original sim in a 8000 a 800 and a 800se clone with no issues at all if you follow what i wrote and used the correct files.
Ive also used clone sims on original motherboards. Not sure why your sim is not recognise i guess you will have to live with the 500hd having the original sim.
