[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.
But i think u have to change the efs folder into a .tar file to flash it.
DO IT AT UR OWN RISK!

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.

U need a root explorer app and of course root! Also
The steps are little bit tricky...
Step 1
Make a copy of your EFS folder on your sdcard using root explorer and then backup to your computer [ to have another copy if you have to format the sd card sometime ]
Step 2
Delete the EFS folder (Make sure you have the BACKUP in a safe place as mentioned in STEP 1) from the root of your phone using root explorer.
Step 3
Do a Factory Reset. After that, navigate to the root directory of your phone.
Step 4
Go to EFS folder using root explorer; delete “nv_data.bin” and the “nv_data.bin.md5” files.
Step 5
Go to your backed up EFS folder on your sd card, copy the “IMEI” folder to the EFS folder at the root of your phone, then again go to the backed up EFS folder in your sd card and copy the ” .nv_data ” file to your EFS folder at the root of your phone using root explorer.
NOTE: the dot in first of nv_data is not a mistake, copy the “.nv_data” file.
Step 6
Make another copy of the “.nv_data” file in EFS folder in your phone, so you would have 2 copies of “.nv_data” in EFS folder.
Step 7
Rename one of “.nv_data” files to “nv_data.bin” and another one to “nv_data.bin.bak”
Step 8
Open Command Prompt in your Windows PC (Terminal for all you Linux users) at the ADB tool path, or run Terminal at your phone enter these commands:
adb shell (use this command if you use ADB, if you’re using terminal, skip it )
su ( When the option comes up allow the superuser to access the file system by clicking “grant” on the phone screen )
chown 1001:radio /efs/nv_data.bin
Step 9
Reset your phone…. after that you have your original IMEI. you can check your IMEI by dialling *#06#.
You have successfully recovered

It seems to me the nv_data files are not present in the efs folder.
I was just going through steps but I didn't find these files.

I have backed up the files before flashing the phone using the twrp & Samsung tool box. But in both of the backups there is no nv_data files available. N currently in efs folder there is no no_data file.

the dot in front of .nv_data means they are hidden. you probably won't see them

HwOTA for Huawei P9 Lite

HwOTA for Huawei P9 Lite​1. On the phone, make a backup of all data (since during the upgrade all data will be erased). This is an obligatory condition.
2. Unlock your bootloader: (There´s no way around it (unfortnuately), but after the procedure your device will be locked again, so don´t worry!). The device will make a factory reset, so once again, BACKUP your files!!!!!!!!!!
3. Enable ‘USB debugging’ and ‘OEM Unlock’ option from setting>developer option>. To enable Developer Options, go to About phone and tap the Build Number 7 times.
4. You must download three zip-archives with a full "Full OTA" firmware on which you want to flash (If you look through in the FF (FirmwareFinder), you see there are 4 archives for China and 3 for other locations. You must to download for the version what model and location you will have after the firmware);
5. Add the downloaded files to the folder "HWOTA\Update" and run the .cmd file, it will rename them automatically according to the template:
- update_data_full_public.zip to update_data_public.zip
- update_full_....zip to update_all_hw.zip
- update.zip don't rename
6. After run the universal batch file update.bat in the "HWOTA" folder, which will provide an opportunity to choose the required work option (change firmware/rebranding (change location)). FOLLOWING INSTRUCTIONS ON THE SCREEN OF THE MONITOR - the entire process is accompanied by prompts.
At the end of the process, everything should work fine... Be prepared, the bootloader will be locked after changing the location or firmware as a FullOTA.
7. If suddenly it turned out "bootloop" - go into the stock Recovery and make wipe.
PS: To change the firmware using the SD card, you need to create a folder "HWOTA" on the SD card and copy three firmware archives with the changed names (see above). In the batch file select item 1 "SDCard HWOTA directory"
HwOTA.zip
