I Try To Solve this Problem By "Direct Unlock" I Thought That This Problem Can Solve With "Direct Unlock" .
2G (GSM Only Work) (3g 4g Not Work)
In HiddenSimUnlockProcess (2945#*851#)
"This Phone Is Permanently Locked And Cannot Be Unlock"
This Problem occurs due to attempt up to 10 Wrong Codes.Now Unlocking By Code Impossible.So I Try "Direct Unlock".
Phone Details When I Unlock It.
Firmware : 10m
Android : 4.4.2
When I Unlock D851 By Direct Unlock Method it Unlock Sucessfully. 🙂
After Unlock 3g 4g Works Great But In "Hiddensimunlockprocess" it show same error
"This Phone Is Permanently Locked And Cannot Be Unlocked’
Than I Upgrade D851 To 20E(5.0.1) It Again Locked. 🙁
Same Problem 2g Work. 3g 4g Not Work.
Please Help Me To Unlock it Permanently.
