[Q] Generic IMEI after OTA 4.3 upgrade

Hello to everyone, I was wondering if anyone can help with this. I have a Galaxy Note 2 branded by an Italian company (3hg Italia). It recently received its update to Android 4.3 (update N7100XXUEML2). It was the official update OTA, the phone is not rooted and it had the stock ROM on it. The update somehow messed up my IMEI making it appear as the generic 0049 forcing me on "Emergency calls only" mode. I already tried flashing the same ROM with Odin and repeating the update with KIES, but while the updates always results successful the IMEI remains 0049. I never made a backup of the EFS folder for this phone since I haven't rooted it or flashed any different ROM on it yet. There is any chance that the phone made an automatic backup? I live in the States right now and Samsung tells me I need to ship it back to Italy to have it fixed, but that costs a lot and would take forever, and I would much prefer try to solve the problem locally. Any suggestions would be greatly appreciated, if not for any fix that I can try myself, at least some place on the West Coast that can fix the problem!
Thank you!
Lorenzo

Oh I forgot to add that because of Hardware problems I recently sent my phone to Samsung and they replaced the motherboard, which fixed the problem I was having. I don't know if that could be related!

I'm afraid that fix works just if you have your actual IMEI, I instead have the generic IMEI that starts with 0049. But I will check it out! Thanks!

Then you should simply flash another modem from here : http://forum.xda-developers.com/showthread.php?t=2044937 ... flash a custom recovery first.

So I found someone nice enough to give me a hand with this situation, but still no luck yet! Here what they say:
At first glance, the EFS data on the phone was corrupt. I re-generated
that data and restored it to the phone without success.
The GSM radio itself is operational, and the firmware for it is
installed and functional. diagnostic data flows to the towers and back
to the phone but it's not reading the IMEI from the copy of
nv_data.bin contained within EFS. I've re-generated and installed
those files as well, again with no luck.
I rolled the device back to it's original factory firmware and radio
baseband, then ran through the update for the radio baseband, which
also regenerates the contents of EFS, and still no luck.
Given the situation, anyone have other suggestions?

try flashing your official firmware through Odin. other users solve their imei problem by doing that. see also if you can access engineering mode with that official firmware.

lets wait for others specially those who are expert in android for some advice. I'm just an ordinary security guard so i can't help you much with your problem. what i have suggested you from my previous post was the last thing I did when my phone finally worked. for 4 days i been searching for solution because i also have an IMEI problem. i flash back to official rom, flash patched modem, flash other roms to no avail until such time when my phone doesn't boot because of broken partition :laugh:. if you still have warranty restore it back. if you're already out of warranty and you have money, you can it send it to service center.
P.S.
you can also try this if you have courage. i was able to make some secret codes work but i have'nt tried if it works with engineering mode by modifying hiddenmenu in /efs/carrier/hiddenmenu. use efs explorer to open hiddenmenu and change it to ON.save it and restart your phone and see if engineering mode work. remember that you have to be in official firmware and also rooted to do this. if its not working then you'll just have to wait for a much better solutions from devs.

Help with ZERO networks!! Before I burn this THING!!

Okay story so far, got Zuk Z2 from BG China to replace Mi5 that had a tumble
After a couple of weeks I decided to flash Custom Rom (LinageOS *UNOFFICIAL), seemed fine then I lost Network totally on both SIMS.... Zero bars! I've tried all sorts of ROMS and flashes of Baseband firmwares but to no avail. Now I think I've confused myself.
So if anyone has any advice before I cast this device from a high roof it would be most appreciated.
Thank you :good:

You flashed already different basebands via fastboot, erased modem after that?
Tried flash stock ZUI via qfil?
After all no network? IMEI's are there?

When it first gave up network I checked IMEI and it seemed to have duplicated them for both sim but after I QFIL back to ZUI 2.5 they returned perfectly... I've gone through the whole erase modemst process but still FUBAR....
Even stripped the device down to bits and checked the internal connections.
He strange part is I get the emergency only msg on sim so guessing the network is recognised but the signal is -90 dBm at best, getting to as bad as -130 dBm.
Even considering writing the IMEI from old bust Mi5 to handset to see if this would help...

Yeah I guess every other android and iOS device I've either rooted or jail broke was pure luck and the huge amount of posts on many sites including Lenovo regarding this baseband problem are all very similar 'lab rat' experiments.
Thanks for the constructive advice and answering my plea, great to know that xda developers are attracting helpful and intelligent like minded users and owners....

I had a dabble with QCN and managed to replace corrupt IMEI's but still didn't help. Can't be sure the BASEBAND was correct though.. I'm yet to try a full FACTORY DEFAULT configuration as suggested but will be this week.
Been suggested the IMEI may be blocked for some reason but seems unrealistic as it was working prior to FLASH.

so look likes it just ignores sim card. Try with another sim. Did you buy this phone from a telecom provider? It could happen that the flashing did some damage in the low-level firmware. If it's the case, you'd need the original provider's software. I don't really know if it can be the case with note 5s, but other models had this issue back then.

Without imei, no network will obviously come.
If it at least detects the sim, you can manually flash the imei. After that, it should work provided the phone detects the sims correctly.

If you have the fastboot ROM, then reflash it.
If it doesn't work, then grab another ugglite from someone, install twrp, make a backup of the modem partition.
Then on your broken mobile, make a twrp backup of the modem.
Copy the files from working mobile twrp backup to your twrp backup and replace them.
On recovery, hit restore.

Have the same issue in Mexico when upgrade to MIUI 10, tried some things and nothing works, so i went to my carrier provider, they check my number in their system and everything was fine, so they proceed to change my SIM Card and vuola, network returns and till now, no problems.
It was like the upgrade cause a failure in the Sim Card.
Is the first time something like this happen in my flashing life.
Hope it works for you too.

I have a problem with my Redmi note 5a lite. My baseband is: 7_GENNS_PACK-1.108 857.1.109523.1 (I doubt that this is not the correct baseband firmware), IMEI are OK but my phone is only emergence calls only.
Can any help me?
Thanks in advance.

Question Oneplus 9 Pro T-MO (LE-2127) Revert to stock and fix modem. Will donate.

I flashed my device using the Indian MSM Tool and I am unable to revert back the stock T-Mobile flash using the T-Mo MSM Tool. Now my mobile radio will not enable. I tried flashing multiple T-Mobile modems that are posted on here and that did not fix the issue. So let me summerize.
Can someone guide me to 1) Flashing back to the T-Mobile stock firmware from the IN version, and or 2) Help me get my radios working again. I'd be willing to donate to whoever can help me resolve this issue!
Thanks!

Thanks, unfortunately it didn't work for me. My IMEI, MAC Addresses, and fingerprint functionality is still working. Now it's not recognizing my SIM card at all.

India MSM is known to screw things up and make devices think they are LE2120 instead of whatever it originally was, but at the same time, that's what makes it able to also flash ColorOS over to Oxygen easily...
I remember people solving something like issue on this forum, might need to search extensively.... I haven't had my OP9P for over 6 months now probably, so I can't help much... best of luck!

I really hate to say this. But I don't think there's no coming back from India os. I did the same thing not once but twice. I called T-Mobile and used my insurance. Only way. Read the topic in this forum bout the India msm tool. Idk if u noticed how much different the India os is from the eu and global os. But if there's away I wanna know also. Cause now the only msm tool your going to be able to use is the India one. But you can update to the a12 one of the color or oxygen I can't remember but ur modem will come on everything will be fine for a few days then it will start messing up again.

I think you're right. I'm going to RMA it with Oneplus.

I thought with my persist, modest1, and modemst2 I could SMT flash it and restore those files but I get a OnePlus write protection using edl and the OEM Unlocking option will not enable in the OS now. Hopefully they warranty repair it. That's my only concern. It's fairly new lol

Sorry I am just going on what that one thread was saying. And my experience I had to make TMobile believe that it was the phone breaking. Be sure to switch it back to the TMobile os. If the msmtool doesn't work fastboot flash it back before u take it back. The 2nd time they went through my phone saw I had the xda app they really started questioning me. I grabbed my phone back and said umm why u looking in my phone privacy dude. You're concern is only with network and data not my apps files and folders. But just save ya some trouble

Maybe its a bit off topic... but what do we learn about it? NEVER buy a carrier branded device if you want play with root. The lower price is not worth. I learned that over 10yrs ago xD

What sucks is I have the modemst1, modemst2, and persist image backups but I cannot unlock it to upload. I am trying to modify the MSM Tool settings.xml to patch the modemst and persist images and I almost had success using the SMT Downloader but I think I don't have the offset bytes set properly to match the partition table.

Beg your pardon, I used the Indian MSM to unbrick before I was aware of it changing my TargetID to IN. Now I have to use a modded MSM tool to flash TMO firmware. I use Python3 to extract the .ops file, then open settings.xml, remove the "Target" line at the bottom encrypt back to a .ops file with the name out.ops and then flash that with the MSM tool. Then it will flash the TMO firmware and you are good to go.......

- op6 user - its destroyed now
but as i see that u cant use any other msm but the indian one? right?
i destroyed my op6 system and partations before,
OnePlus Agency, tried to fix it but no luck, i fixed it by msm but not the normal one
if 9pro msm is the same as op6 so you should do this
first, take twrp backup of EFS and MODEM partations and VENDOR ( idk if vendor is important but for precaution )
take another backup of EFC and MODEM by any root apps for precaution too
use the t-mobile msm flashtool and press on verify
the SMT mode should be able to use now
go to options, turn on the COM box or whatever
start flashing with SMT, but i think its high risk bc idk what error you get by normal flashing
keep in mind that SMT Mode will reFlash all known partations and hidden, hidden like MODEM, EFS, etc
my story with this is long, but funny for me, and big lesson..
thx for allah
@ripclap
edit: forget to tell that u have to restore the EFS backup, u should root t-mobile version or idk if u can restore it with some apps without root i dont remember
with op6 old firmware there is something called nvBackupUI it allow us to backup EFS and Restore it by one file
i know this maybe too old now but it may help
edit2:

3- https://www.droidthunder.com/how-to-backup-efs-imei-on-android-phones/
