Hi, I have been playing around with an i9505 and thought I had made a proper backup of my EFS data. Unfortunately that was not the case and I have only backed up the EFS partition, neglecting the others.
I then later chose the *#9090# : "DM/DUN/RmNet over HSUSB " option and allowed it to wipe my EFS data, believing I had a suitable backup.
Upon restoring said backup, my base band is unrecognized and I have no IMEI. The phone also fails to receive any signal.
My question is, will it be possible to recover from this mistake or should I consider it a brick?

You can try to use Kies 3 on your laptop to reload the stock firmware.Then put your phone in Download mode (with the phone completely off, press and hold the Volume Down and Power buttons) and connect it to your PC. The OS will install the necessary drivers (this may take a few minutes) and then you can select Tools -> Emergency firmware recovery in the Kies software. It'll prompt you for the model number (enter it in CAPS) and IMEI (both found under the battery) and then it'll download the correct firmware and then install it .If the problem still persist try to follow this thread and it might help you, and if still doesnt fix Go to service center for a repair. Have a nice day.
Thank you for you prompt reply. I have tried using both versions of Kies and have not been able to do an emergency recovery.
I have since managed to get the "Qualcomm NV Tools" of "EFS professional" to work and I have confirmed that my IMEI is still present on the phone.
When i try to uses the *#9090# hidden code, all I get is a blank screen. My belief is that the modem is simply not communicating with the phone anymore due to the option I chose "DM/DUN/RmNet over HSUSB". The message I saw was:
"Warning : Must read below guide All Communication between AP/CP- will be disconnected !
To return the normal mode, you must download efs12.tar file !
All NV data will be erased !
Really you want to use RmNET ?"
I'd really like to be able to undo this if anyone can help.
Dial *#1234# and tell me what appears pls :fingers-crossed:
Typing *#1234* gives:
Version
--------------
AP : I9505XXUEMK9
CSC : I9505H3GEMJ2
Apologies for the double post. I am wondering if I backup the NV data from another working i9505 with "Qualcomm NV Tools" and then write that to my phone if that will fix the problem?
I have made a backup of my existing NV and examined the resulting text file. It would appear that nearly everything is blank, except for a couple of fields, one of which I identified as IMEI (Block 00550 / 0x0226). This field is read only which explains why I still have an IMEI.
I would be extremely grateful if somebody could send me their backup, minus the 00550 (0x0226) block so I can avoid having to convince a friend to let me play with their phone.
I have been further investigating this problem and have found that the modem is not communicating with the phone. I believe this has something to do with NV items greater than 65536. This would make sense, as the usual NV backup tools do not save/restore items with a higher address.
Of particular interest to me is :
69674^"HSUSB RMNET Over HS Core"^"USB*"
But the versions of QXDM that are available do not seem to be able to read/write this value. I am hoping there is a command of some form to do this but I am unsure.

Hi mate,
As soon as you clear EFS folder all data IMEI SIm LOck and EFS utils are gone. What u need to do just install new EFS with utils via Odin3 downloader. I have done this way many times. We call this EFS12 file for recovery, buy IMEI and CAL data will be erased. As soos as you get 0/01 IMEI you can try repaur IMEI for example Z3X BOX

I kept backups of all the images replaced and restored them as I had trouble loading recovery. I doubt images from another (different) phone were a great idea.
Recovery is working again but some image said there was not enough space on device to restore !?!

[Q] SGS4 i9505 Lost Some EFS Dats
I did the same with SGS3 GT-I9305. *#9090# corrupted my S3 efs, imei and baseband.
How did you resolve your issue?
Please help!!!
Thanks
Hello I've been trying very hard to change an imei in a QCN file of an S4. I've seen that the later versions of qpst doesn't support editing as they say but I've also tried EFS Professional but no luck. I used nspro to write the same imei as back of the phones to unlock the phones and flash a qcn file with qpst but it changes the imei and I don't want that as it's supposed to be the imei of back of the phone always. Hope I get help, I've been trying this for weeks and googled too much that I couldn't figure out and wouldn't work at all. Thanks for reading!

Send it back to LG for repair. messing with the IMEI is illegal (short of backing up and restoring) and as such banned from the site.
Hi friends and users of XDA.
I now flashed latest firmware for my device model (SM-N900S), but says "No network".

Did you buy this phone new or used? Is the imei properly displayed when you dial *#06#? Does the imei from the phone screen match the imei on the battery label?
Restore your backed up EFS folder .
Worth trying a factory reset first and or flashing again .
Hello Everyone,
I have LG G2 802.
I was flashing different roms without backing up my IMEI. Last week i saw that my IMEI number has been changed (I think it changed after i flash .tot file).
I google and get to know that it is possible to bring my IMEI number back. I tried EFS Professional software but it did not work for me. It can change the value of ESN which is 00000000 but it can not change MEID & IMEI number. Please help me with this matter.
