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

on the XXDME6 base - you can not install old modems,
because it will cause for unknown modem & imei status.

FIX IMEI
If YOU type *#06# it says imei null.
Also another thing - that there is no baseband version
#######################################################
the fix
open your SGN II - under the battery you'll find IMEI (in my case)
write - on a paper
turn on GPS
on the dialer - *#*#82043036#*#*
next go to GPRS -> WRITE IMEI ->Reboot
Will it allow modem downgrade, ie DME6>DME4>Stock 4.1.1?
I want to downgrade to 4.1.1 from present DME6 (UK BTU N7100)

Ok, i tried this.
1. Had DME6 on my device.
2. Flashed your DME4 modem which was successfull. The IMEI was still present.
3. Flashed Stock 4.1.1 BTU. IMEI was lost and had emergency calls
4. Flashed DME4 again, and IMEI came back. So i am back on 4.1.1 which i wanted.
The dial string ...8204... doesnt work on my N7100 UK BTU, although i didnt need it because i got imei back.
Successful..........
I had two copies of my efs. I reflashed my efs in 4.1.1 (XXALJ2 modem) and I got the imei back. Everything back to normal. Phew...
the method is when u lost your imei go to efs folder by using root explorer and copy that efs folder to your eternal sd card (i mean backup efs folder to sd card)
then flash a stock rom via odin then your phone still not have service and imei (maybe fake imei is 0499...)
root your stock rom, install root explorer and copy efs backup folder from your sd card then paste with the efs folder in your root directory
=> reboot and your imei is back
i have successful with this method

But how can you get efs back, when the backup you made was from a corrupt efs? Maybe you just didn't flash the latest modem when you were on me6, and your imei wasn't corrupted at all.

no your efs folder is still there with your original imei but the modem has hide or can use it ( so backup it in to sd card ,i mean copy it)
flash your stock XXDME6 BASE WITH XXDME4 kernel in there package, dont change any modem
then use root explorer delete your efs folder (it will show delete fail but all sub folder and files in efs have been delete)
=> reboot your phone ,now android will creat neccessary file for efs folder ,copy your backup efs folder from sdcard to root efs folder (replace all)
reboot and u will get your imei

Let me understand, for I have installed the MF6 without backup my EFS (and now I stuck with this rom):
You installed a previous stock rom with odin, installed that attached modem (ME4) and all right... but you then installed ANOTHER stock rom with odin and was all right?
You will need efs backup made prior to installing MF2. Without it you will not be able to revert to stock with working modem.
i have updated my ROM based on DME6, I have a nandroid backup of my prev ROM DME1 based, tried to restore it. Baseband/modem got restored but EMEI invalid, its start with 0049. It displays my network logo but cant register to network.
This means Im stuck with DME4 modem. Hope our Devs here would be able to resolve this issue with the new released firmwares.

Tried flashing the modem 3 times now...what am I doing wrong? Any Ideas?

I think you got yourself in a tuttifruti mix not knowing what are doing,not having efs backup and flashing a bunch a things trying to fixit.
Now you have to go back to your last working build and stay there until samsung release a fix so we could flash withaout worries.
Good luck to you sir.

EFS is the one partition you don't want messed up. It contains the IMEI info for your phone.
First things first: you should try to do a factory reset from the stock recovery you have installed now and see if it boots.
If this fails, then: do you have any NANDROID backups made with CWM recovery? If you do, did you also backup the EFS partition? If you did, try to restore a full NANDROID backup and you should be fine.
If you somehow get your phione to boot up and you can't get a network signal, then it means you EFS partition (and IMEI) is corrupted. If you don't have a backup for that, the only solution is going to a phone service repair shop (at least I don't know of any way to recover that without a backup).
Good luck

No. You'd screw things further. Don't flash backups from other devices. The IMEI is unique for each device.
Did you try the factory reset from the recovery you have now?

I don't know. Try it. I think there was an option for it.
You could also try reflashing stock firmware with Odin. If everything fails, I suggest taking it to the nearest phone service repair shop. Restoring the IMEI is a more complex operation. I think a JTAG is required. Not sure though.

I do not have the time unfortunately to go into details. But please search on google: "Odin explanation" or something like that. A good example:
http://donandroid.com/understanding-odin-a-beginners-guide-on-odin-buttons-checkboxes-629
Unfortunately like I said, none of the available options can help you.
And never try to use Re-partition unless you really know what you're doing. That repartitions your internal memory to a different layout (like number of partitions and sizes) and requires a PIT file specific to your device.
In the future, always make full NANDROID backups before flashing anything. This will also backup your EFS partition. There are also applications like this one:
https://play.google.com/store/apps/details?id=ma.wanam.efs
And many more examples which I am sure you can find on XDA in your device specific forum. This way, if your EFS ever becomes corrupted, you can easily restore it to a working condition.
Cheers.

Did you backup your LUN5 partitions in qfil? If No, then find someone with same variant and get a LUN5 backup partition which must include modemst1, modemst2, fsg, fsc. Boot to EDL, erase the mentioned partitions and replace with the one you got. If the partitions you get does not match, you may get a OPID error mismatch
