GW620 NVRAM restore to fix airplane mode /No SIM

[sad_but_cool1]

i had many problems related to NVRAM ago, no sim card recognized,no 3G, always in airplane mode, ... etc.
finally , i restored my phone, by restoring an NVRAM backup from a working phone.

I uploaded the backups from v10 amss and from v20amss.

GW620_NVRAM.zip

and

Multiupload.com - upload your files to multiple file hosting sites!

**you must care about successful backups , the output must be 170/171 kb size , not less !

**you must use LGMDP_US.zip release,"Google it"

and the phone must be turned on "not in EMERGENCY mode" to backup/restore NVRAM.

the easiest way to restore a backup is to make a backup first , then to replace and rename the backup file "attached" to your backup file,cause LGMDP has some issues recognizing NVRAM backups "paths/names".

then to restore it,and rebooting.

in some cases , you may need to write the settings from service programming , like the pic below.



note that the red hints "in pic" is essensial settings , and the yellow is optional , as in my case and provider settings that works for me
