People, i'm going crazy with this...
In these last days i've been trying to make my Gionee work but with no results...
All works GPS, WIFI, FM Radio and even NFC... all but what is most important in a phone, the ability to make and receive calls/sms etc... No signal...
At this time i believe its the modemst1 that is damage some how... the modemst2 is ok and it has the IMEI...
Both of this files are at
/dev/block/platform/msm_sdcc.1/by-name, and by what i can tell their both 1.5Mb...
It seems that modemst1 might contain other relevant information for the process of registering on the network...
What i ask now doesn't requires an expert knowledge of Android.
I believe that any Android user should know this operations, for his own safe guard!
During the process
THE SIM CARD MUST BE OFF THE PHONE
Changing IMEIs
This process can be skiped if you trust me and believe when i say that i dont wont your IMEI.
Just want my new phone to work again... As soon has i got your backup and restore it, i'll change the IMEI to my own...
Requirements:
EFS_Professional_2.1.80_BETA - Download
HERE
This tool can be used to change the IMEI. Change it 00000(...) before start the backup and after completed change it back to your IMEI.
During the process
THE SIM CARD MUST BE OFF THE PHONE
1 - Open application and choose "Qualcomm NV Tools" press ok to confirm
2 - Select the Diagnostics Port and press connect
3 - Go to "Secure Ops" and press SEND the Diag password
4 - Check the IMEI (Dec) box and change the IMEI
5 - Below the IMEI (Flipped) area make sure its selected Phone and press Write
6 - Disconnect and reboot the phone. Confirm if your IMEI has changed before starting the backup process
Process 1 - Backup to IMG files
Requirements:
- ADB available on your PC or Terminal Emulator app installed in your phone
- Phone rooted and BusyBox installed [get BusyBox from PlayStore its free]
Using the Terminal Emulator or ADB in command line, type these commands:
Código:
su
dd if=/dev/block/platform/msm_sdcc.1/by-name/modemst1 of=/storage/sdcard0/efs1.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/modemst2 of=/storage/sdcard0/efs2.img
Process 2 - Backup with TWRP Recovery
Requirements:
- TWRP Recovery installed - Download version 2.8.6.0
HERE
1 - Reboot into Recovery Mode
2 - Press Backup
3 - Select only the EFS partition
4 - Rename the backup (optional) and press Backup
In both processes you can choose just to share with me only the
modemst1 backup.
I believe that the IMEI information is on the
modemst2.
The backup procedures dont have any risk to your phone.
Changing the IMEI carrys some risks... If you're not sure of this, just DON'T DO IT.
Or simply trust in me, and backup without changing your IMEI
Again, people i just can't put in words the suffering that i've been in this last 2 weeks...
Please anyone, just end my personal hell...
Thanks you all
Gracias a todos
