[Q] Lost IMEI after flashing new ROM and modem - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

I've flashed latest modem using TWRP and then flashed ROM Unofficial Cyanogenmod 12.1 and gapps.
Since then i lost IMEI,baseband etc, I can't even connect on WIFI.
I did save a copy of efs folder on my sd card and I backed up previous 4.4.2 android. I have restored old system and I flashed several older modems from list in forums (for my i747M) and i copied efs folder from sd card to root, but still no IMEI.
I did tried EFS Profesional but it wont start, says ADB server error.
Any ideas how to solve this? thanks

any luck mate? I'm in the same boat as you but I have wifi still. Commenting to follow or maybe you have a solution.

Did you flash the bootloader too? It is recommended that the bootloader and modem match.

No, I only did the modem. Should I do the 10.2 install or install modem + bootloader back to back?

Just install cm10.2 for now. If you only flash the mjb modem, you should be okay as I recall seeing that the phone already had the mjb bootloader.

[Q] Issue flashing from 4.2.2 to 4.3

Hello All,
I have been using Illusion 4.2.2 and want to go to 4.3.
I have been facing the following issues -
1) After upgrading to the latest cwm (6.0.3.8), I tried flashing PA 4.3. With a clean wipe and format system, it gave me a status 7 error (installation aborted).
One of XDA members redirected me to this - http://forum.xda-developers.com/showthread.php?t=2321310. I followed this and following is the screenshot of what I have after upgrading the bootloader : (Below jpg which says "Just after upgrading bootloader)
2) I could now flash the rom but when I rebooted after flashing , I don't have root access and neither do I see any att network / data . Following are the screenshots -
(Just after flashing 4.3 Page 1/2 and No root access after flashing 4.3).

Some roms you have to turn on root access; should be in the install post. Are you running the right rom for your device?

I eliminated that possibility because the same thing happened with two different roms (PA 4.3 and Illusion 4.3). I am on ATT and this phone is a ATT phone , and I am flashing all roms within this thread

I know with illusion you have to ::Settings -> Developer options -> Root access to apps and/or adb. to get root access. Where are you getting basebands from? The latest is I747UCDMG2 but I747UCDLK3 should work too. Get them from HERE

Baseband is Here. I would suggest MG2 baseband as it is more compatible with 4.3 than older than LK3. Get it from the link i just gave you and follow instructions on the page. Only use odin for reverting back to STOCK.

Huh thats weird. The only thing i can think of is something is wrong with the rom or you are flashing a non d2att rom.

I suspected that but since a lot of people are already using that rom and I made sure I am downloading d2att , those things are eliminated.
I am thinking the 4.3 flashing erased my previous efs folder and that is why it cannot find my imei number anymore - resulting in no network.

When you get imei back i would suggest a nvbackup to make sure you keep a good backup of your imei.

I had a nvbackup but since I flashed a different of baseband , I was not able to recover.
Anyways, I flashed stock through odin and looks like I have my network back.
Any recommendation of which 4.3 rom will not cause this again ? Anyone ?

[Q] Galaxy S3 softbricked

So after flashing a ROM that was from before 4.4.2, I had been unable to restore it to anything I had before. I thought I had made a backup but I guess I accidentally erased my SD card in CWM. So now I'm stuck with recovery and download mode. Using ODIN I've tried flashing a 4.3 stock ROM but it didn't work and I've been unable to find a current ROM that I can use in ODIN or find a way to push a zipped rom through to my internal SD card while in download/recovery. Can anyone help me here? I don't even need it to be on stock I just need a way to get my phone up and running again. I've been working on this all night and still havent been able to find what I need.
The simplest method may be to get an external SD card, copy a custom ROM to the card, boot into download mode, flash a custom recovery via Odin (I highly recommend Philz Touch), reboot into recovery, and flash a custom ROM from your external SD card.

I got a ROM to work, but now I have no network access. Wi-Fi works okay though. When I hit Mobile Networks in Settings it says "Insert SIM card to access network services." I read a little about this and I think I have to flash the radio, but I'm not able to find one. Maybe someone could provide a link? And I just flash that in ODIN also, right?

I flashed a modem matching the MJB firmware. Still nothing. Ive been reading about maybe it needs a different kernel, or something to do with the EFB so Ive thought about using EFB Professional to wipe the stats.... I havent even tried doing a fresh install through KIES but im wary to mess it up again
Install terminal emulator from the play store and enter this:
getprop ro.bootloader
This will tell you your base firmware/bootloader version. Your modem will need to match this.

After flashing the modem, does the imei appear?
You need the NE4 modem no matter what you run. Nothing else will work.
If you use a 4.3 rom you will need the MJ2 or kt747 kernel though.

Help! IMEI & Baseband unknown post update to Cyanogenmod 4.4.4 due to user mistake

Help! IMEI & Baseband unknown post update to Cyanogenmod 4.4.4 due to user mistake
I was on cyanogenmod 10.1 with Andoird 4.3.1 and was looking to upgrade the ROM. I made a nandroid backup thorugh CWM and ADB as well: adb backup -apk -shared -all -f C:\samsung\backup.ab Then I downloaded the below:
boot_CWM_I747UCUEMJB.zip cm-11-20141027-NIGHTLY-d2lte.zip & pa_gapps-stock-4.4.4-20141025-signed.zip.
Logged into CWM did a factory reset/wipe, but also did format a couple of partitions (grave mistake as I guess that deleted the EFS). After this updated the above three files. The phone came up fine, but now cannot make calls due to the unknown IMEI & baseband. I tried unrooting through ODIN & sammobile stock rom but it fails due to the latest bootloader.
Currently I am trying to restore the ADB backup using adb restore C:\samsung\backup.ab
I am not sure this would work. Any help in fixing this issue is appreciated.
Thanks

Did you try flashing the latest modern and bootloader or loading an older cm11 ROM?
The modem/bootloader is latest I think. I did try going back to an older ROM which is on 4.3.1. Everything works except the voicecalling. No mobile network available. And IMEI & baseband shows as unknown.
What boot loader is on your phone? I believe you need the KK modem and bootloader for the latest CM11.
I really appreciate your help and prompt response. The bootloader I have is
I747UCUEMJB
I think right now I just want to go to stock if possible. Do you think it is possible? If yes, I would really appreciate if you could guide me in the right direction.

Now that you have the 4.3 bootloader on your phone, do not ever try to downgrade the bootloader as this will brick your phone.

Losing IMEI everytime!

Hello guys!
I have a problem with my wife's Note II (should be 7100).
Starting from a stock 4.4.2 I tried installing MIUI 8 through PhilzTouch. Everything went fine, I also installed Open Gapps but I had lost the IMEI. The phone didn't recognize the sim at all (INSERT SIM).
So I tried to restore the working EFS partition (of the 4.4.2) but still the IMEI was corrupted.
I had to restore the whole ROM backup to get the phone working again.
Then i tried with RR 7.1 but I had the same problem.
Basically it seems that everything i flash make me lose the IMEI :|
Any suggestions? Thanks!
The phone was running the latest bootloader and modem before flashing a custom ROM? I also recommend using TWRP to flash, not CWM or Philz.

I'm not sure that the Samsung firmware the phone was running was the latest. Didn't think it could make any difference :/
Can you pinpoint me to the correct files?
Oh and will try with TWRP as you told
The latest n7100 firmware is here: https://www.sammobile.com/firmwares/database/GT-N7100/
To find out about the phone's bootloader and modem, you can install the Samsung Phone Info app from the Play Store.

Installed the latest n7100 firmware then flashed MIUI 8 through TWRP... Still unknown baseband and no IMEI
Tried to restore EFS and MODEM but no luck.
Same for RR 7.1.1
I'm trying Eclipse now sigh
UPDATE 2:
Eclipse working good at least!
Maybe it's just a bug in MIUI? I'm not sure as I don't have a note 2 to test.

Need help getting sim card to be recognized after flashing cm13, Thanks!

I have spent the past 2 days trying to get a new cfw installed on my phone that didnt have many bugs. I settled with the cyanogenmod13 and read that it was good for a daily driver. At first i installed the wrong gapps and would make the keyboard crash, but now that i figured that out i need help with getting the rom to recognize the sim card. I tryed reflashing with twrp 2.8.6.0 because i read that it would flash the modem correctly, but still no luck. i'm fairly new to flashing and have only done it 3 times in the past. So now i made an account here to ask for help.
Thanks in advance to all the help i get here.
Is the phone running the latest bootloader and modem? You can compare the versions in the phone to sammobile.com.

Thanks for your rely, Im not 100% sure what you mean by modem as im fairly new to this whole business. I will go to the website to see what i can find. Where can i see that information about the modem i am currently running?
I recommend matching the bootloader and modem version to each other.
You can download the Samsung Phone Info app from the Play Store to learn about the phone.

Ok I did some research and learned that the modem is the baseband number that shows in the about phone section. This is currently unknown or my guess non existant and that is why the phone says that the sim card is not inserted.
I also learned that i can use ODIN to flash the modem/baseband directly without the need to reflash the whole rom.
I dont know where to find the file online for the modem that matches the rom. I have spent a while looking around and have seen older posts of people saying that they have experienced the same issues after flashing cm13 on n9005 Note 3.
Here is what i am running on my phone:
- Cyanogenmod Version: 13-20151031-UNOFFICIAL-hlte (maybe there is a newer version to this somewhere that has this issue fixed)
- Baseband: Unknown
- Kernal Version: [email protected] #5
- Build Number: 1
-hlte-userdebug 6.0 MRA58K 2127f69904 test-keys
What do you think? And thanks for you help so far. :good:
The simplesting may be this: update TWRP to the latest version. You can flash the img file from TWRP.
Once TWRP has been updated, create a nandroid backup of the existing ROM.
Download the latest ROM from sammobile.com and flash the whole ROM. This is the simplest and safest option IMHO.
After flashing the stock ROM and making sure the sim is recognized and IMEI is correct, use Odin to flash the latest tar version of TWRP , boot into TWRP, restore backup, test your sim.

Wouldnt I be able to flash the modem with odin as long as it matches the phone model? or will that cause problems?

Updating to the latest version of TWRP is a bad idea. If you update to version 3.0+ you can't install ROM's that use the AROMA installer. The newer versions of TWRP do not support it. The best version I've found is 2.7.8.0 to be able to handle any flashing.
The biggest problem is the sim card in my opinion.

The sim card works fine in Ecuador, I have used it before flashing to cm13. I found the website of the ones who made the build and noticed that the version that I have downloaded is 1.33 from Oct 31, 2015 and that their latest updates on the channel log is version 12. I will download and flash latest build and she if the issue is fixed.
I was referring to the card bot being recognized in CM, not on a stock ROM. Thanks.
