[GUIDE]No BASEBAND version, NO signal, CANT call, etc...

Hi everyone, I made something funny that worked today
Scenario is the phone has no IMEI, no BASEBAND, cant enter the service code *#*#197328640#*#*, can’t call and gives force close, and in short the phone is useless. HAHAHA lol.
The history of the phone is HARD BRICKED after my big brother flashed a kernel onto this phone after upgrading to 4.0.4. he wiped user data and along with the EMMC file, it became unresponsive and doesn’t turn on anymore.
I had it recovered using MEDUSA box and after I got the BOOT/DOWNLOAD mode. I flashed a firmware with DXxx.xxx baseband. im so glad that the phone was completely working again, ALMOST hahaha. When I inserted my stupid SIM, it doesn’t want to pick up signal an found out that there is no BASEBAND version as I checked it on about phone, or dialing *#1234#
I have done some research and I knew that I is gonna be the RIFF box again that will fix this thing. What am I gonna do to a phone that doesn’t pick up signal at all. I flashed it over and over again even the MODEM alone but still no luck.
Things that I have done to have it work though with a wrong IMEI
1. Root the phone
2. Installed SGII repair
3. Backed up the efs folder (either using ROOTexplorer/the SGSII repair app)
4. Downloaded the EFS pro
5. Downloaded the .NET framework 4.0
I tried repairing the EFS using the GSII repair but still no good after reboot, and used the the EFS pro to repair it but still no good. After rebooting couple of times I don’t have signal.
Imma make this short now
1. Root your device using whatever method u can use
2. Install root explorer and copy EFS folder to your internal SD card then paste it somewhere on your computer. (name it as ORIGINAL EFS)
3. Now use the SGSII repair (download it in app market)
4. Use the repair method then back up the repaired EFS folder on save/restore option (REPAIRED by SGSII repair app)
5. Paste the .tar file to your PC/Laptop and extract it and name the EFS folder as repaired EFS folder
6. Use the EFS pro and click on format the EFS folder. (make sure before doing this, you have repaired the EFS and BACKED UP the repaired EFS using the SGSII app)
7. Connect your phone to your pc and mount the storage to your PC/Laptop
8. Copy the extracted file you have backed up on number 5 (using winrar)
9. Copy the content of the extracted repaired EFS by the SGSII repair app to the ROOT EFS folder of your phone.
10. Then click the Repair NV data / Attempt NV recovery
11. If that did not work just reboot the phone first and do the number 10
12. Reboot again the phone
13. Once rebooted the phone will then have the icon of w/out sim, has baseband, and once you inserted the sim it will then have coverage to your carrier
14. Do it with a little bit of luck
Enjoy your phone with wrong IMEI and the screenshots I have put on this thread are, after I have done everything but previously it doesn’t show the BASEBAND version and everything. but after i have done THESE steps, it suddenly displayed the baseband version and i had signal
I tried doing this but it has just gone with the no baseband version again

These steps worked for me and I have a working phone with wrong IMEI.
Worked for me :highfive:
Any helpfull steps / posts / links that would completely recover the ORIGINAL IMEI would be gladly appreciated

A phone with wrong IMEI will be blocked in 2 days in my country

I accidentaly flashed in a i9100G ROM on my i9100 (regular one, no NFC and nothing extra), not even an unlocked one, and i lost all my phone thingys.
But i am a bit nerdie, so i searched for my problem here, and discovered that flashing an 9100G modem is a really bad idea, so i decided to flash an LP7 MODEM/RIL back and evrything went to normal (at least in my case)

better backing up your EFS folder to your SD card cause it contains a very important file...

Network Connection Error

Alright, so I paid cellunlocker to unlock a new to me Note 3. Not blacklisted, everythings good on that end.
my IMEI shows as the correct number with two extra digits - not sure if thats my issue.
However I cannot connect to any mobile network. Well thats not true, I can see I'm connected to their tower but cannot get any phone calls, texts I just get the message on the screen.
I didn't back up my EFS partition, having 6 android phones so far all, rommed, and everything I never had to do that.
I understand its likely that this partition is messed up.
.. So how can I restore it?
I'm rooted, I'll install a recovery I don't mind any of that. however I do not have a backup of my EFS partition. Is there any way to extract this from a stock file?
Can I just use Kies or something to flash the entire software and restore this partition?
Seeking some guidance from the Note Experts.
Thanks,

- The extra 2 digits after the IMEI is the IMEISV. It is not the issue.
- The EFS partition is store inside your device, not in the stock firmware. Of course you can not extract it from the stock files.
- You can try to flash the entire stock firmware (using Kies or Odin). Sometime that may help to fix the problem.

Appears to be a case of delayed blacklist or something.
Didn't show up in any searches and not to my carrier, yet later now it does appear it is.
Now to return it to the carrier so they can get it back to the owner, and to track down the ass I bought it from.

(HELP) with NV DATA

Hey Guys I need some help with Nv data (EFS )
The NV data baseband is I9500UBUAMDE nonetheless my firmware baseband is I9500UBUGNJ1
I think this is why my phone do not have a stable conection with cel-towers...
So I need to know, how to update the nv data without corrupt it?
Kindly regards,
AG

Just flash a stock ROM using Odin. This will ensure that the bootloader and modem match.

Already did it some many times... Without results...

The phone is missing the imei and MAC address?

No one is missing...
Phone signal Goes out and in.
However while the phone has signal. I can call and navigate on internet..
Do you need the efs folder?

If the phone has an imei, then it seems like the efs folder may be fine and something else is happening.
So flashes are successful in Odin?
Could the phone be blacklisted? Was it ever dropped? Tried a different SIM card? Tried our SIM card in another phone?

Ok, I have to be honest... I was on 4.4.2
I try to use galaxysim unlock. However EFS was v2 and I restore a v1 efs folder in order to unlock the phone. It works. However after upgrade to 5.0. It start to fluctuate the signal...
Note: v1 and v2 are versions in matter of security of the EFS folder...
That is how this how begins...

Did you restore the original version 2 efs? Do you have a backup of the original efs? If not, I'm not sure if an nvwriter will help.

I think I do not have one...
What should I do?.....

I'm not sure what to suggest. Maybe Google nvwriter and see if it works with your phone.

Lost my IMEI, IMEI 0000000000 and i did not backup EFS folder. GS4 SHV-E300K Korean

okay so i tried to install xposed framework via recovery since it gave me an error during normal install, the device rebooted the got stuck in a bootloop, i flashed the latest rom for the shv-e300k from sammobile, everything worked great and the device booted into touchwiz, but there was 'No service' and the phone didnt connect to mobile network, when i dial *#06# i get IMEI 0000000000000.
i tried flashing different stock and custom roms, but nothing worked.. i tried a method to restore imei by copying EFS folder and using the .nvdata file, problem is there is not .nvdata in my EFS folder, I even tried installing cyanogenmod 13 and installing xposed framework on it together with the IMEI changer module, I typed my IMEI there but still no service..
PLEASE HELP!!!!!

The NV Data no longer lives in the EFS folder but is located in a hidden partition you cannot access. Wanam Partition Backup could have backed up and restored that partition for you if you had used it, but since you didn't, you'll have to take the phone to a service center and have the service center restore the IMEI.

can you please tell me how to get to that partition using wanam partition backup ? and what is the partiton called ?

All the app does is back up and restore that partition. It doesn't let you access that partition, and besides, it's too late anyway. Your IMEI is gone, and using the app now would only back up what you currently have.
This device needs to be taken to the service center.

same problem here

respected dev. i have the same problem. i flash a different firmware and now my phone baseband is unknown and imei is null. after a few days of checking its still not working. i have recovered its last working condition details as you can see in the photo attached

If restoring stock firmware does not restore the imei, you will probably have to have it fixed by jtag service or repaired using a programming box like an octopus box: http://octopusbox.com

Or have the phone serviced by Samsung, as discussing tools to rewrite IMEI I don't think is permitted on XDA.

I think discussions about restoring the original imei to the original motherboard/phone is okay but discussion about changing imei or serial number to something other than the original is not permitted.

Could you please check this.

check this but before this i want to ask that can i flash other firmware so that i can get baseband back. if i get baseband then i will use the above software to install the New Imei on the Phone. Tomorrow i will try every possible method to get back the phone to life and then if i fail, i will take it to the service center but if there is any possible way that you can help us so please assist and we will appreciate your assistance. thanks Regard Muhammad Ismail

That Xposed module won't work as what it does is spoof the IMEI for apps that have reading or sending the IMEI in their permissions. It does not change the existing IMEI and cannot be used to restore a lost IMEI. It requires the Xposed framework to function in the first place, which should give you a really big clue that this won't work.
If you want to waste the time and try it I'm not going to stop you, but the resolution to the problem requires tools only Samsung has. Android can't rewrite the IMEI as the IMEI is part of the phone's low-level firmware that Android cannot touch.

check your phone box if you have lost the imei

IMEI lost?

Hello, I flashed a stock through MiFlash, but it gave an error, I flashed a stock that I already had to backup, B13 MiFavor5, but when I search + # 06 # I get IMEI 1-2 unknown, I have EFS backup, two doubts, only flashing a compatible modem to recover the signal from the operator? or restoring the EFS partition ?, if you restore EFS, how do I do this?
(I have backup of the EFS folder)

Flash the A2017 modem first. If it doesn't work then use the EFS backup

You can flash an EFS backup with the EDL tools ,I've used it for back ups and restoring ,seems to be the most reliable method for flashing to me . Easy to set up as well . Read the forum page very carefully and you should be fine

Hello, first I want to thank the answers, and I was able to recover the IMEI by flashing the modem, but it is different from the one specified in the box, and even recognizes the chip from other operators, but specifically the one I use does not recognize it.
two questions: Is there any problem with the IMEI being different from the one specified in my box ?;
How can I make this specific SIM work? (I already tested it on other devices and the SIM works.)

At some point your device has been factory replacement chip set put in and this prosuss has cleared that up this is why the IMEI number has changed.......
