This is a reoccurring problem with the S4 processer. Coming from an S3 these threads are littered throughout all carriers.

Hi !

I found the following stuff on another website for QPST :
Quote:

To make a backup:
Open Software Download from the Start Clients menu.
Click on the Backup tab.
Make sure your phone is listed under port.
Select the location you want to save your backup.
Click Start and wait for it to finish.
You should now have a QCN file of your NV.
Save the file in a safe place.

To restore:
Open Software Download from the Start Clients menu.
Click on the Restore tab.
Make sure your phone is listed under port.
Select the location you saved your backup to.
Click Start and wait for it to finish.
The phone will attempt to restart if it fails don’t panic just manually reboot your phone it may take longer than usual but you should be fine.

Can it be done before any modification to the phone in order to restore it directly in case of any issue like IMEI loss ?

Thank you

Yes, you can restore the .qcn backups and it should fix the IMEI if it is corrupt or blank.

In a normal restore you would receive an error message that NV_UE_IMEI_I is read only and was not written.

Hello madmonkey57 (or anybody else with the knowledge)

I flashed the CM10 ROM that epinter posted. Everything was working OK until sudently my phone lost the data and voice signal. I cannot make calls or use data and a recording from my carrier says that my phone has been suspended. Ichecked for an IMEI error and no, my listed IMEI is correct (I used QPST to restore it because it was listed as (0) when I installed the Feench ROM before). I've been reading xda-developers forums looking for an answer, but the only one I have found so far involves an EFS folder, but it seems that is only used on Samsung phones.

I don't know what to do now, as I cannot use my phone at all. I retried to install other ROMs, restore an old nandroid backup I had, and other solutions listed on other sites, but now I'm stuck. Nothing's worked so far.

If someone have a hint or knows the name of an Android guru on other forums, please let me know.

Thank you very much for your help.

If neither your nandroid backup nor a stock ICS ROM are working, it may be a hardware problem...

EDIT: on second thought, this "phone suspended" notice... I have the feeling your carrier blacklisted your phone i.e IMEI. Try another SIM card maybe... Could be working with another carrier...

It would be interesting to know why... usually they blacklist when the phone is stolen. Never heard about blacklist because of a custom rom... ?

Indeed, it was black listed. I received some data with one ROM when my IMEI was (0), then I manually entered the original one using QPST and when I flashed CM10 my IMEI went again to (0) and that's when my carrier suspected a bad use of the line and suspended it. I don't blame them, it is a good security measure.

I have to go to the service center and I had the fortune to talk with a really well prepared technician. They restored the original ROM and now all is well. I will try new ROMs for sure, but I will disconnect my data service before it connects to the network.

Thank you for your suggestions.
