you would have had to make a backup of your original rom. you can always try un-rooting then do an ota update then root again. Just giving some suggestions

I have a Coolpad F1 which is identical to an A310. (NOT A210).
I will make a TWRP (v2.8.1.0) backup so if you want to try feel free to.
NOTE: You will try this opn your own risk.
But, really, how much worse can it get is it is already corrupted?
Also I don't want any money.
(Unzip the ZIP file and copy the TWRP folder to /sdcard)
Hit that Thanks button if it helped!

This is NOT a flashable zip.
Extract the TWRP folder from within the ZIP and copy and paste it to your sd card.
Then go to TWRP recovery and restore the backup called NVRAM backup.
KEEP IN MIND! This is a A310 not A210 NVRAM so it may not work.

You can't restore a TWRP backup with CWM.
It's late night over here. I will flash CWM and backup NVRAM tomorrow so you can restore it with CWM.
I hope I don't forget.

I just came from school. My mom then took my phone because she left hers on her work
NVRAM backup comming in 1-2 hrs.
EDIT: Still keep in mind that this is for A310, not A210 so it might not work. (and I know I said this like 3 times already)

thx

I have a problem. CWM doesn't backup NVRAM seperatly as TWRP does so restoring the CWM backup will break your phone.
Try flashing TWRP.
1. Flash TWRP
2. Make a nandroid in TWRP
3. Restore the file I posted before
Check if it works, if no just restore TWRP nandroid and flash CWM.
EDIT: I just found out that you can fix this by wiping NVRAM and reflashing your stock rom.
Some random A210 stock modified rom HERE

I just realised something. The NVRAM is on the /data partition right? So doing a data rezet should overwrite the current NVRAM with the stock one.
I suggest a backup and the a factory data reset before reflashing the rom.

That would mean you lost your EFS. Unless you backed it up theres not getting it back.

Mi4i full partition corrupted. Unable to restore EFS partition.

Hello friends,
I have a Mi4i which was rooted and Cyanogen was installed.
Suddenly after reboot, the phone stopped booting into the Cyanogen OS.
I tried to flash the Cyanogen again but it did not boot.
I flashed the stock ROM, which is MIUI 6 and the phone booted this time.
Now I could see that the SIM card was not getting detected. And also IMEI number was showing as invalid.
I then deleted all the partitions and tried to recover the phone by flashing using "MiFlash". This time too the Cyanogen OS didn't boot up.
Then I again flashed the stock ROM and this time also MIUI booted up correctly.
Still the IMEI was showing as invalid.
I don't have any backup of the EFS partition.
I checked the stock ROM flash_all.sh script and could not find any efs partition being written (modemst1, modemst2, fsg).
Then from somewhere I got the modemst1, modemst2 and nv_data partition data and I wrote the partitions manually.
After writing the EFS partitions Cyanogen booted correctly. But this time the IMEI showed as "012345678901234" and "012345678901235".
As this is a dummy IMEI, the SIM was not getting registered in the network.
Tried with QPST RF NV manager tool to write the IMEI which successfully did but with *#06# it still showed Invalid IMEI.
Tried with a couple of IMEI flasher and none of them worked.
Also tried to write the IMEI number using AT command (AT+EMGR=1,7,"IMEI1") but the AT command was returning "ERROR"
Please help me to recover my phone.
Now I have my phone with MIUI 7 installed and it is working fine except the IMEI issue.
Thanks in advance.

You can use QPST Tools to program the efs manually, but I've not tried it. So try to give it a try and see if it works

Thank you very much. This method partially worked for me.
I could write the imei number to my phone this time.
But the sim is not getting registered.
Can you please help?
Thanks in advance.

Dump your efs partition, and upload the dump so that I can try to compare it to mine and see if some other things should be used .

Attaching the efs dump from my mi4i.
It will really be of great help to me if you can fix the phone.
In the current efs dump, I could only write the IMEI number of the first sim. I am not aware of the address of the IMEI of the second sim slot.
Thanks for your help and valuable comments.

Can you upload a backup of the EFS Partition from TWRP or from Mi4i Toolkit? Thanks in Advance!

The problem is I don't have the efs backup of my phone. So all the data is lost. Even the IMEI number is also erased.

Try this and see, and I was unable to compare the file

Download the stock firmware from updato.com.
Efs will not be included as that is device specific.
