Now i am using 4.2.2 factory stock from google and i am with radio i9250XXLH1 which is a recommenced one from GetRIL app.
After i flashed the 4.2.2 my radio was i9250XXLJ1 it was not working so i moved to i9250XXLH1 any way bath not working....

Hello, even i am facing the same issue. My Vodafone sim has suddenly stopped working in my gnex here in Mumbai, but other sim cards apart from Vodafone are working fine.
About the imei even my imei had changed to a generic one. I used an app called fu*kdocomo to restore my imei and somehow its successfully restored.
But still my phone cant get Vodafone network. But you can give it a try.
And kindly update this thread if you find a solution to this. Good luck

Hello everybody, i want to extract the efs partition from a phone to restore mine, is anybody here who know, how to make that? I'm lost my imei and i want to restore it. Thank you
i found something strange, my phone have baseband M8937_22.29.02.56q CEDRIC_EMEADSDS_CUST and my friend phone has M8937_22.29.02.56R CEDRIC_EMEADSDS_CUST, maybe here is the problem with the imei?
both phones was bought together in the same day, them had the same firmware at the start, but now i see that is different.

Please do not attempt transferring anything related to firmware from one phone to another, even if they are the exact same phone model, because absolutely no phone is made identical and doing so would totally brick your phone.

ok, but how can i repair the baseband? i have no imei....
There already is a guide on how to retain your imei, does this mean you've flashed an oreo rom?
yes, i flashed pixel experience, but imei didnt come back, and the baseband is strange, the last letter is q, means M8937_22.29.02.56q instead of M8937_22.29.02.56R like the all phones xt1676. Before loose imei the baseband was correct M8937_22.29.02.56R
Hi everyone.
I've just bought this LDU device to a guy, and it seems to be fully functional (excepting some minor things, I can make phone calls and use 4g/5g data connection, etc).
Anyway, I'm a little bit scared that something stops working suddenly, mainly because of the patches that have been applied to make it work, specially for the IMEI (these devices originally don't have one, so it's "patched").
Another thing is that it comes with Android 10, and I'm not sure if I can install another ROM with Android 11 without breaking the patching that makes it work so far.
Anyone with experience with LDU devices could please share some information about it?
Thanks in advance!
Edit1: After some days of testing, I've found the following issue:
-Cannot update via OTA, CSC is WWA which I haven't found anywhere.
-Samsung apps like Pass and Secure Folder don't work, probably due to Admin mode (despite no root app is installed), or it may be related to the CSC too.
The rest keeps working fine so far.
This sounds like a stolen phone i'm afraid. Patching an IMEI is considered illegal.
Any device that has a cellular modem in it (for calls and data), MUST have an IMEI.
If the seller said it didn't have an IMEI, he's lying and you are potentially dealing with a stolen phone.
Thanks for your reply. I thought it was a stolen one at first also (although he told me it was part of a payment from the phone store he works on), but then he had the white box of the LDU devices, so I don't think you can get one of those easily.
Anyway, this device obviously came with a cellular modem because it's working, but I guess the IMEI was patched somehow after reading it in some forums, but not sure. In fact, if you have a way to confirm it, I would be more than happy yo test it and publish the results.

Hi I'm using a Note 20 ultra that was previously an LDU. It came on android 10 like yours, I've currently upgraded it to android 12 via odin and everything still works fine. LDU are fully functional phones put in a demonstration mode and void of imeis, aside that nothing wrong with them. You might wanna install a new battery tho since they're batteries are quite overused because they were Live demo units....
Hello, i have An Galaxy s21 ldu and im wondering how to get it to work. I tried getting it an imei but all of those apps dont work. How to get it to work?

Hello sir, please help me to flash IMEI on my S21 live demo. Where can i find a tutorial for that?
Hi Guys !
Greetings to y'all!!!
I'm honored to be a part of this prestigious community at last and looking forward to give back, someday soon. My huge respect for all the contributing members, I have been using this forum to get help since 2016 and without even posting anything I've always managed to get helpful information to resolve every problem encountered till now ((rooting & flashing)).
:'D
So here goes my first thread:
A friend of mine recently tried flashing stock ROM on his SM-G988B/DS since his update firmware option wasn't working for some reason. Even though it was a success, in doing so he flashed wrong version of firmware and caused network failure, flight mode if tapped got stuck (greyed) (wrong modem was flashed). There was no backup and original firmware number wasn't mentioned so I tried flashing different versions of firmware (U1,U2,U3,U4 & U5) and finally got it working on flashing CP(modem file) of G988BXXU5BTJ3.
However, for some reason I still was unable to make a call, so I searched for it and found out that by dialing *#0011# my IMEI status is NG which is bad , even though my IMEI number is still intact as found on the back of the phone. I researched a bit further and found out that this has something to do with the EFS file and whilst going through comments in another forum I found someone else had the same issue and got resolved by deleting nv_data.bin file and its backup and IMEI folder in EFS file after rooting and reflashing stock ROM. I tried the same but found that nv_data.bin was missing in EFS folder, so I backed up EFS file and deleted just the IMEI folder in it and reflashed stock ROM, have tried flashing different CP versions aswell still no success .
I've seen some videos of Chimera IMEI rewriting and certificate patching and Z3X tool on youtube but in their case IMEI is missing and I don't want to go for those solutions for the instance. I'm wanting to learn from all this exercise and want to know whether what is what and how to resolve this manually (maybe by writing some hex code or script etc) if possible.
Summarized:
Phone: SM-G988B/DS
ROM: Stock (G988BXXU5BTJ3) (rooted)
Status: SIM Card Registration failure ( IMEI status NG)
IMEI : Intact (As on the back of the phone)
EFS file ( nv_data.bin and .bak missing)
Previous Status: SIM Card was working fine before flashing ROM
Your valuable suggestions in this regard shall be highly appreciated.

First, do a TWRP backup, all partitions including efs & modem.
Open the root explorer app, open the efs folder, delete the files named nv_data.bin
, nv_data.bin.md5 & the folder called imei. Then open twrp, wipe all partitions. Flash the latest firmware with Odin.

You can fix NG with auto patch file and and pach cert using support tools.

Guys, first I want to make it clear that I'm not opening this topic looking for methods to change the IMEI, my problem is something that really intrigues me.
I imported the op9p from China because it doesn't have an official store in my country, and it turns out that his version is Chinese (LE2120) and probably the seller flashed the rom IN, EU or NA, I didn't receive it with ColorOS but I didn't pay attention either In that detail, it didn't even cross my mind.
And there's a problem with doing that, the IMEI is only read correctly on ColorOS, or OxygenOS A12, and I wouldn't care about that if my country didn't have a law in place that blocks the operation of the mobile network for cell phones with IMEI " strangers/illegals", recently I received an SMS from my operator warning that in a while my IMEI will be blocked for use on the country's mobile network, so I ran after a solution and discovered that when I went up to OOS12 the rom correctly reads the IMEI. But OOS12 is not good in my opinion, I really prefer to be using a custom rom, and at this point you must be figuring out where I want to go, to be in a custom rom, you must be on OOS11, which leads to this IMEI problem for custom roms.. I even received this mentioned SMS while at AOSPA. I honestly don't have the slightest idea how to get around this problem and not get stuck in stock, I would like if anyone had any ideas please let me know
NOTE:
I'm not trying to do anything illegal with my IMEI, on the contrary, I want it to work properly.
And I am currently on OOS12 NA/Global, and the IMEI is being recognized as it is marked on the label on the cell phone case.

I'm stuck into a similar loophole you could say. Can't upgrade to oos12 cos when I do, I lose my network coverage. But when I'm on oos11 or even android 12 custom roms, network works perfectly without any issues. Anyhow, the lack of stock camera always made me go back to OOS. I even tried flashing other builds on my 9 pro (IN, GLOBAL) but the same result of no network availability. I'm not sure what Oos12 does with the IMEI but whatever it is, it's not letting me update my 9 pro.

you say mobile data network? I think that in your case it would be a good idea to report it to oneplus, but from what I read right here on xda, a port of the OOS camera will soon be released for aosp

Not sure where are you reading such, but oos camera will take probably a WHILE. It's true that some are working on it, but the progress is slow and barely any.
