6300 write pm without sx4 auth on jaf
 

hello!

i just want to share this solution and hope it can be useful to some members of this forum.

i had a 6300 dead and the blue lights on the 2 sides lights up.i flashed the phone on jaf with version 7.21 and its still the same.

action taken:
1.back up crt.
2.erase phone
3.full flash.then phone switch on but imei is 123456 and phone is contact service.
4.write pm using jaf care.no need sx4 auth(if you back up crt then write pm,it will require sx4 auth)
5.then back up crt to restore imei.
6.finally unlock phone on zulea's free software to remove contact service and phone is alive and working perfectly.

NOTE:IF YOU DONT BACK UP CRT,YOU WILL NEED RPL TO FIX FONE AND IT WILL COST MONEY.

hope this info is useful.

I have one pcs of 6300 which shows me "contact service"
I try your way how to fix, made backup crt, try to upload pm, but it requires SX4 active. Your pasr at point 3. and 4. I don't understand. Can you explain one more time, step by step how did you do it?

Thanks in advance
