[Q] IMEI Backup and Restore

I am totally new to flashing. I just backed up my IMEI (created a rfs file using Terminal Emulator and just copied of the efs folder to my sdcard).
My question is that suppose I happen to lose my IMEI on flashing, can I recover it by simply copying the contents of the backed up efs folder to the original folder using root explorer?

yeah, its as simple as that

Thanks but I am not sure how I would do that. I went through the IMEI backup and restore thread. So is this what I have to do?
1. Select the .ops file.
2. In the efs section, add the file and not select the one package option.
3. Connect my phone in download mode
4. Flash
Is this method correct?

Yup thats the way the say it to do.

Have a look at this Thread also..
Gives the basics of different ways of mounting the efs partion.
Its safe to use the ADB method i guess.
But flashing with efs.tar file should work.

[Q] Loop in TWRP ,Please help me

My D802 is loop in the TWRP.
I have tried to install the stock rom or to restore the backup system I stored two days ago.
The TWRP shows that the install is successful or the restoration is successful.
But when I see the folder 'system' by the "File Manager", it only have a folder "bin" and it has no other data , I think it is very strange.
Can somebody help me to solve this problem?
Thanks.

Thank you guys for your support! but I managed to fix my IMEI and its working
below are the steps to fix it which i got from one of the posts, i dont remember the member but thank him a lot
1. Create on your Phone Memory(Not Extrenal sd!!) a folder called "efsbackup"(without quotes)
2. Copy all files & folders from the EFS backup into "efsbackup" folder(The files are like in the picture)
3. Using root explorer, go to "efsbackup folder, select all files & folders there, and click Copy.
4. Still in root explorer, go to "efs" folder of your device(It is located where all main folders like data, system, etc.).
5. In "efs" folder, click paste. It will ask you if you want to replace your files, select replace to all files(So all your files from "efsbackup" folder will be in "efs" folder)
6. Now open terminal emulator
Write the following:
Code:
su
Then click enter. It will ask for super user permission, give it permissions.
7.Now write:
Code:
busybox chown 1001:1001 /efs/nv_data.bin
8. Then click enter.
Now write:
Code:
busybox chmod 06755 /efs/nv_data.bin
Then click enter.
Reboot device. Now everything should work.

1. Open SP Flash tool. Press ctrl+alt+v
2. Under menu item either window or options there will be new menuitem "write memory". Click it, a new tab will appear.
3. Click the tab, select your nvram.bin file. In the start address field, enter the start address of the nvram partition (get the start address from scatter file)
4. Click start and wait for the process to finish. If all goes well you should see an "OK dialog"
5. Disconnect the phone and reboot.
PS: Make sure scatter file is loaded before proceeding with above steps and at least "preloaded" checkbox is selected
Thanks

Doesn't matter it is one and the same thing, it' only an extension. What you have got is actually a RAW dump of the nvram partition. You can either name the raw dump file as .bin or .img or anything else. The extension naming is only for satisfying some tools as they either look for .bin file or .img file. So just go ahead and follow the procedure.
Thanks

Thanks man....
Really really thanks....
I will try this procedure as soon as pollible...

I does this procedure, but nothing happened...
My SN are not resetted, everything is just like nothing happened,
What should i do??
Please tell me...

Edit by help of notepad++,Go to scatter file n edit by finding nvram data,change is_download to true n change the file and bin name as same as nvram data which u have,I hope it helps

Did it work ?

Hey bro , problem solved?

You can use the TWRP to flash the nvram.img. Go to the folder where the file is saved, there you can see an option in the bottom right corner "image file" select it and flash the image as nvram partition

SPFlash tool can't Flash partitions other than the default listed ones directly. In the scatter file you can enble other partitions but it will not work. It will always give error 6045. Two flash other partitions using SPFlash tool, you will need to enter Advanced write mode. Here is how you can do it. But first revert to original scatter file.
Steps:-
1. Press CTRL + ALT + V to enable advanced write mode.
2. Open the advanced write mode (there will be an extra menu item under either option or main window menu.
Once you click that item, an extra tab will be added (write memory)
3. Go to newly added tab, select the partition you want to flash. Enter the starting address of the partition (get it from scatter file) you want to flash. Press start button. If you have correct drivers, the procedure should start within 10-15 seconds. Wait for the process to finish (you should see an ok dialog)
4. Disconnect and restart the phone. The first start may take slightly longer.
If the partition flashing file itself is corrupt, your phone may enter boot loop or stuck at the screen, so do backup your stuff
Hope it works for you
Thanks.
