Baseband and IMEI unknown after attempted downgrade. - T-Mobile Samsung Galaxy Note5

Hi! I had tried to downgrade my note 5 back to marshmallow, and have no imei and cannot connect to the network now. I have flashed back to nougat and still have nothing. Could anyone please help?

Hello all! It seems when I tried to go back to nougat I wasn't installing the latest nougat update, which caused the baseband to be mismatched with the bootloader. I installed the latest version of nougat (which I paid $15 for because software update websites did not have it to download in fast speeds and I was anxious that my precious note would be dead) by flashing it with Odin. I am posting this update to make sure if anyone else has the same problem they will successfully be able to recover from the issue.

Unfortunately, I did exactly what you've done, came here with same problem, and still need solution. My baseband info is null, IMEI blank, and my phone can't receive cellullar network.
the worst thing is, I forgot to backup EFS before doing this :crying:
what I've tried :
1. flash again to stock nougat : didn't bring back my IMEI and baseband info
2. flash again with stock MM : didn't bring back my IMEI and baseband info
3. flash with lollipop rescue firmware T-mobile (4 files-got somewhere in google), odin failed when flashing s.param, as in pict attached below
Really need help please, what else can I do to solve this problem. I don't want my note 5 become an iPod Touch :laugh:
If someone have link for rescue firmware for N902T or solution for odin failed above, will be grateful

i also have the same issue....is there anyone who can help us

I just encountered the same thing except I'm still on the start screen. I can't get into the device due to FRP but I feel I may have null IMEI and baseband too. If I don't get it fixed soon then I guess I'll just sell it or something.

This ERD1 flashing also worked for my SM-N920T which lost its baseband, IMEI and subsequently SIM Network. Now its fine again.

Hello guys I did the same thing on my Att Note 5! And found the easy fix to get everything back to normal!
Fix:
1. Just use Odin as usual!
2. Put files in appropriate slots AP, BL, CP, CSC
3. Go to options and check nand erase all, re-partition, auto reboot and F. Reset time.
4. Hit start and wait for the green Pass! Let it reboot as usual and Boom, all will be back to the way it should! [emoji106]
Hope this helps!

Heya @Goody68, tried that because I have the same problem (no efs back up, baseband unknown, imei null) but re-partition doesn't seem to work. Odin fails and log shows:
<ID:0/005> Can't open the specified file. (Line: 1892)
<OSM> All threads completed. (success 0 / failed 1)
Any idea what to do next?

this what worked for me after sleepless nights for just reading and searching the google. lot of website gives instructions, but non of them worked for me.
i am not good at giving instruction but i will just say what i did, and it's up to you if you will follow it. this is just to add idea for you that may work for you.
i apologize for not providing link. just google them and add "xda" as keyword to your search as much as possible.
downloading from sammobile gets error when using winzip or winrar to extract them. just use 7-zip. they are working i guarantee you.
the root of all these baseband unknown, no imei error is after i flashed to nougat first version.
what i did exactly that worked for me after hundred of trial and errors from the tip of all website and for my own experiment is,
1. i rooted my phone and flashed Nobleltetmo_N920TUVU3DPG1_Stock_Deodexed.zip to make my phone lollipop version.
2. then flashed as of today feb 2, 2019, i downloaded from sammobile N920TUVS6ERH1_N920TTMB6ERH1_TMB.zip downloaded from sammobile, when extracted this is the file N920TUVS6ERH1_N920TTMB6ERH1_N920TUVS6ERH1_HOME.tar.md5
i don't know but it worked. probably luck. anyway just try the latest version.
this is all i have tried that did not worked for me, i have deleted others to free space on my pc. just keep away from these list.

[Q] HELP! I need to flash a modem if anyone can help?

Ok well, I got my replacement Moto G and everything was working ok on 4.3. Then I decided to manually flash Kitkat through adb after unlocking the boot-loader, and now I'm getting no service at all. lol. Um, yea So I have flashed the same firmware on the original Moto G that I had and had no problems flashing it. I don't know why I'm not getting any service on this one? I forgot to mention that I twent back to 4.3 through adb seeing that might of helped and did the kitkat upgrade after, and nada!
Baseband Version: MSM8626BP_1032.340.63.00b
System Version: 172.44.4.falcon_umts.Retail.en.US
Build number: KXB20.9-1.8-1.4
Under status I'm getting Unknown Network, Mobile Network type Unknown, Service State: Radio off, Mobile network state, disconnected, Bluetooth address unavailable. That is what is missing under those sections. I'm assuming it has something to do with the radio/modem. If anyone has one they can let me flash for the Retail US version, I would highly appreciated. :good: Thank you for your help!
maybe a solution

Same issue as OP Help.
I am having the same issue as the OP. I tried to install modem 2 before 1 the way OP stated. But I still cant get any service on my phone. I also have the 1034 version of the device suited for T-Mobile. I tried to flash the stock radio as well but Im not getting any service. If someone knows what the issue is please help.
By the way my wifi is working just fine. Its the network I cant connect to. I tried my sim card and it work in another phone.
Thank you for any help.
I'm also having the same problem. I have a US global model XT-1032 Moto G. No matter what the heck I try to do the radio always stays off on the phone. It worked fine prior to the 4.4.2 OTA update.
I've tried flashing just the modem from the 4.4.2 and 4.3 US firmwares for both the XT-1032 and XT-1034 versions and neither of them work, it always shows the network as unknown and the radio being turned off.
I have even tried erasing the modemst2 then modemst1 in that order and then flashing the modem with the non-hlos.bin file hoping that if I did it in reverse to the normal order it would fix the issue.
The sad thing is that since I unlocked the damn bootloader to do this, now I can't get any kind of warranty repair done on it by Motorola.

I wanted to report that I fixed my problem with my moto-G, it turned out to be a XT-1034 instead of a XT-1032. I posted a blog post with a link for downloading the file that I used to fix the problem. Basically what I had to do was flash the 4.4.2 modem for a Retail GB model moto-G. This fixed the problem. here is the link http://doctorevil30564.blogspot.com/2014/06/how-to-fix-motorola-moto-g-xt-1034-that.html
UPDATE: the Retail US 4.4.3 factory image from here Blur_Version.210.12.32.falcon_umts.AWSRetail.en.US fixed the radio on my XT-1034 so no need to use the previous method if you are having the same issue, just try flashing that version on your XT-1034

Extremely weird stuff going with S6.

Hey, so I just bought a second hand s6. When purchasing I only checked the major hardware stuff like everything in *#0#* and the calling etc and didn't bother to check other stuff which is stupid on my part. Anyway, when I got home and tried to use themes nothing happened. The Theme Store button didn't do anything when I tapped it and still didn't work after I added a samsung account and everything. There a bunch of other issues as well such as all the options in the System Update menu being pretty much useless, they all did nothing when I tapped on them.
Sorta got fed up of all this and decided to do a factory reset. Once I get back into the phone after reset, the screen grid option that you get when you pinch in was greyed out which is really annoying since the 4x4 is just not for me. Then I decided to root it so I can just get a custom rom in and get rid of all these issues altogether but when I got into download mode it said the phone's version is G920P instead of G920F. The guy I bought from said it's the international G920F and it even says G920F in the about phone section. The confusing thing is that it instead says G920P when I get into download mode. I don't even know what it is anymore, is it sprint or is it international ?
Anyway, is there any fix to all the issues I've been having like the screen grid option being greyed, the system updates menu being useless and the theme store not working at all.
Also, what do I do about rooting and roms ? Do I treat it as a sprint variant or an international variant? It'd be a pretty massive bummer if it's sprint since there are pretty much no worthwhile roms for me.
Pls halp

This bad or good ? ;-;
Also worth mentioning that it says 920F on the back as well. Would flashing the whole stock firmware of 920F through odin be a feasible option ? It says 920F on the back so it has to be that variant right ? If this is possible please direct me to a firmware I should flash and a guide of how to do it, bit of a noob here.
Bumping this up before going to sleep, any help would be appreciated, thanks.
When I get mine s6 there was a sticker at the back showing its serial number. It's written on its box also. If you have this you can use Samsung kias to flash the firmware designed for your phone.
There's an S/N at the back, I'm assuming this is the serial number. I want to root and install some custom roms though but I'm not sure how to go about doing that since I don't know what version my device exactly is.
Pls halp
Attached a screenshot with more info. Hope this helps.
I'm not sure what the previous owner did but your device code name zerofltespr is P variant.
I see, so I should treat it as a sprint variant for rooting and custom roms then ? Just making sure before I go through with the stuff so I don't brick the phone.
Also, anyone got up to date links for how to root and install custom recovery on the sprint version of the s6 ?
@Skyrus5150
Download the Phone Info app for Samsung, take a screenshot and post it here.
Settings show G920F, that can be changed by editing build.prop but the back cover shows 920F as well? That's the odd part.
The previous owner has somehow got the device name to show zerofltespr which is a G920P (Sprint). Not sure how he got a CDMA device code on a GSM device.
Boot into Download Mode, see what it says there, that can't be changed as far as I know.
It will show the actual model number, whether it's 920F or 920P.
Here you go, what should I do. Yeah the bootloader says 920p but the back is 920f, maybe the phone was opened or smith.
Pls halp
Downloaded root checker, according to it the phone's rooted as well. Downloaded TWRP Manager as well, should I just go ahead and install custom recovery with it and select S6 Sprint in the device options ?

Rooted with 0x0 KNOX, some dark magic is at work here. Maybe engineering bootloader?
Anyway, just download a G920P stock firmware and flash it. Then proceed to do a factory reset/data wipe in stock recovery and have your phone back to normal, which is a G920P.
Back says G920F, but it should show an IMEI and S/N as well, do they match those of your phone? I'm certain they don't, but still... check.

LOL, the back says 920F but I entered the IMEI into two different checking services and they both show it as a 925F (S6 Edge), this phone is going places.
Anywho, the stock firmware is supposed to be flashed through odin yes ? Could you please link me to a guide and links to download, maybe even let me know which specific firmware I'm supposed to install. Sorry, I'm a former LG user and I have no idea how Odin and all these shenanigans work. Also, the phone will remain unlocked even after flashing stock firmware, yes ? Currently using it in Pakistan.

Aah a fellow Pakistani. Where are you from? Drop me a PM, I may not be allowed to post some links here.
Yes, stock firmware is going to be flashed with Odin. Will send links for downloading, and guide you as well.
Yes to your second question as well, once Samsung phones are unlocked, they will stay unlocked.

I saw some threads talking about octoplus box but I still have my efs Backed up my and SN and IMEI still show up.
Please help me I am here I am willing to learn and search online. I've tried everything i've found online.
Hi.
Try to use Smart Switch > Software Update and Initialization to recover your firmware, hopefully you get your network back.
Tell me what happens, gl.
Sent from my SM-G920F using XDA-Developers mobile app
almost same thing on a long thread here, no solution so far:
http://forum.xda-developers.com/galaxy-s6/help/g920f-network-issues-t3291903
I am seriously considering it could be sim reader issue, or some cold solder somwhere on mbo.
My IMEI was also showing in settigs, but when dialed *#0011#, in stack 1, there was "IMEI NG", after write cert operation via octoplus, it says IMEI OK now, but NO SIM, and no mobile networks menu still.
Same like you SIM is detected when inserted or removed, and phone offers restart to access mobile networks, but after restart nothing changes, KNOX tripped by previous owner, phone was in three 3rd party repair shops, where they made even bigger mess than it was, when I brought it to them.
i had the same issue when i upgraded to mm so i sent to shop they had to downgrade it to 5.1.1 and use octobox to fix it
Thanks for replying Legend.
But even though I did the software Initialization in smart switch once before it is not working for me now.
I've tried twenty time while reinstalling and restarting the pc I even tried a different pc I get the same error message every time. "failed to run firmware upgrade unknown error occurred".
any other thing to try?
you could try to restore that backup you have, from when everything worked and then flash 5.1.1. bootloader and modem for that csc via odin before rebooting
According to Smart Switch with your sn it is ILO so you need 5.1.1 bootloader and modem from ILO 4 file fw package.
*I just managed to flash stock 6.0.1 via odin (even though It failed at hidden.img... it boots normally) still no sim card tough.
*I realized that maybe all of this happened because when I flashed stock via smart switch for the first time I didn't have my original s/n so I put one from the internet and it wasn't my region.
meaning I flashed stock of UK and it still worked for a month or so, so that's weird...
*Thank you brenner that is a good idea and I will try now
question how do I extract the bootloader and modem out of the fw? I just open the tar archive and take the boot.img and modem.bin files and flash them as is?
nvm found a guide

There are .tar-s which are single file, and 4 files, the ones with 4 files has separate bl/modem
btw, isnt sn written on back of the phone, along with IMEI?
OK, I've flashed the nandroid stock 5.1.1 (LMY47X.G920FXXU3COJ1) and its bootloader and modem from sammobile.. still doesn't work!!
How can this be? everthing is EXACTLY the way it was when it was working!
and no, my model at least doesn't have the S/N and IMEI written at the back, and I didn't keep the box
any other suggestion anyone?
*also there are so many post in subject if I ever find a solution I will make a guide.
-bump-
still no solution..
I've flashed back to current stock ILO...
Meanwhile looking for a lab with octoplus box, still would love solving this at home
At home or not, I would like to solve it too
Bought a second hand S6 the other day and was working perfectly fine until I carried out the update. Now on 6.0.1 and am getting the exact same problem, my SIM works in every other phone. Has anyone found a solution for this?
Not that I know of, except hw replacement, which cost as a used phone with 1+ years of warranty (6 months warranty on motherboard after replacement, on motherboard only)
But I am willing to donate to whoever finds a solution for it.
No i think your problem is a S/W problem, i have 2 G920F with this problem, one of them is 3 binary and another is 4 binary FW, now i work on it if i can solve this problem i told you here.

S7-G930F/FD Issue

Hello everybody,
Yesterday I went to local phone reseller and bought used SM-G930FD for a good price. It's condition is flawless, came with tempered glass aplied also stickers on camera and heart monitor. Tested before purchasing and everything was working. When I came home only then I noticed that it had SuperSU installed and at that moment ran android 6.0 with 2016 security patch. After some reading I loaded the firmware from 2nd post via odin selecting three options :https://forum.xda-developers.com/galaxy-s7/how-to/official-stock-firmware-update-odin-t3369431
1)Auto reboot
2)Re-partition
3)F-reset time
Note that the phone had no "secure startup" option so I didn't need to set pin. After it booted up the phone no longer detected my sim, which prior worked with android 6.0 also download mode says it's SM-G930F, but software reports it being SM-G930FD and I have option to select 2 sims in menu?
Also yes, the knox is tripped, which I didn't notice before purchase, I have few options in mind, which one would you do if you were in my case?
1) Return the phone with reason that there's no signal and choose another SM-G930F which 95 percent will have knox tripped aswell, as they're all used.
2) Solve the no signal issue myself and continue using the phone with knox tripped as the condition of phone is 10/10 (Is my phone more prone to viruses and malware without knox? I came from iphone, but prior used android and take good care of my phone)
3) Ask for refund
Note 2: The seller also gave me a 6 month warranty which might work/might not depends if the seller knows about knox?
Thank you.

Solve the no signal issue if you know how to do that ! (No your phone is not vulnerable to viruses) !!!!
Is your IMEI is ok ??

Im downloading SEB(Baltic firmware), that should fix the sim issue. Can't tell you why I loaded netherland firmware
Imei should be okay, incase not, how do I check?
Could you possibly check how fast does this file is being downloaded for you? For me 6-10 hours.
http://updato.com/firmware-archive-select-model?record=965C8F3C8E2911E7963AFA163EE8F90B
Had the same exact issue. I've noticed the presence of SuperSU and I know what does it mean on a Samsung device. Checked both IMEI (*#06* and on the back of the device) and turns out it was changed or swapped to a different one... and just like you, my phone was running Marshmallow with Security patch from 08-2016. I though there was no problem updating it to 7.0 but after phone booted up i've noticed it lost network connectivity (kept on "Emergency calls only"). Started to research and found out that there is a box which is called "Z3X box or Samsung PRO" which modifies the IMEI and then patches the phone in certain way it becomes dual sim even thought is not really (you will see a second IMEI with only zeros and phone becomes G9XXFD but it's really a F only). The solution, at least for me, was to get someone to patch the modem once again using the box i've mentioned and I got signal back. Only downside is you won't be able to factory reset nor update in any way, flash another ROM or remove root because you will lose the patch again and lose signal. Hope I was clear.

You should download the latest firmware from sammobile
To check IMEI *#06#
If it is like 000.. or "null" then it is IMEI problem and then You need a z3x box to properly fix it (or give it to mobile repair shop)
If it is okay , then no problem . . . . .

Yes , z3x box is the best toolbox for changing or repairing IMEI or for doing other useful stuffs
but if IMEI is okay then there is a option to repair network
it directly repairs the efs folder and get the network active again
In my case , I am using S3 i9300 and whenever i flash stock firmware with odin then the network issue always SUCKS even if IMEI is okay !!!!!!!!
There's 2 Imeis, one with numbers, one with 0000

Yes, he could patch the modem using Z3X but like I said he couldn't be able to update the phone nor flash custom ROM's. That's the catch with the S7

Check if the one from *#06# is different from the one on the back of your phone, look carefully because sometimes it can be 90-95% similar

I returned the phone and instead he gave me a golden one. This unit runs 6.0.1 with 2016 March 01 security patch. Only one imei and know is not triggered. The drawbacks are some dents on metal frame, slight burn in of Facebook, didn't came with tempered glass and no more stickers on camera or heart monitor. I plan to flash the baltic firmware via odin, is there any chance it'll trigger knox? I'll do repartition as well

Switch from SM-G930U Nougat to SM-G930T Oreo (T-Mobile) possible?

Has anyone successfully (or have any info regarding) converted from a SM-G930U (7.0) to a SM-G930T (8.0)?
I have a completely stock, working S7 SM-G930U (that I previously converted from SM-G930V), updated to the latest Unlocked 7.0 version. I was eager to get Oreo, but didn't want to wait for 930U firmware so decided to just switch to the T-mobile version because I'm on a T-mobile MVNO. However, when I tried just flashing the G930T files with Odin it fails right after the "emmc_appsboot.mbn.lz4" step (whatever that is). This made the phone unbootable and would just boot loop.
I was able to successfully recover the phone by re-flashing the G930U files again after downloading from Updato. So the phone is working again, but I'm right back where I started.
So, my question is: Is there something different that I should be doing, or some other secret to go from U -> T, with the intent of getting Oreo? Would it work if I flashed the 7.0 version of 930T, then taken the OTA update?
Edit: As indicated in the responses below, the solution is the latest Odin version (3.13.1), and I successfully converted. Good luck!

You need to update your Odin. Oreo ROMs use a new compression format that your old Odin can't handle.

Update to what? I was using 3.12.7.
Edit: OK, looks like I found it. 3.13.1 is for Oreo, etc. Thanks for the heads-up.
Hi. I have the same Verizon s7 and have also got a 930u rom on it but I am desperate for Oreo. Have you managed to successfully flash the 930t oreo rom? And if so where did you download it from?

Yes, I was successful. You can get the firmware from Updato here: https://updato.com/firmware-archive-select-model?q=SM-G930T&exact=1&r=&v=Oreo(Android+8.0.0)&rpp=15
But ignore their update instructions, as they are outdated and meant for Nougat and below. You need Odin 3.13.1, from here: https://forum.xda-developers.com/galaxy-s8+/how-to/guide-flash-oreo-g955fxxu1crb7-using-t3755789.
If you try with an older Odin version it will soft-brick your device (as I found). Otherwise flashing instructions are simple and the same as when you switched to 930U.
Great thanks. I will try it!
I can't get it to start. I've loaded up the firmware into odin, connected the phone in download mode and it won't start flashing. What could I be doing wrong and is it worth doing anyway?

I can't tell you if it's worth it (I think it is). But you also need the Samsung USB drivers installed on your PC, and you need USB debugging turned on, etc. Make sure you have a working connection before flashing.
It worked. Thanks!
Does it has the whole bloatware thing???
I'm still gonna flash it, but I wanna know, cuz I'm not in my house right now, and also is it laggy???

Define "bloatware thing". There's like half a dozen T-mobile apps, plus a small handful of other "pre-installed" things like Whatsapp, etc. Virtually all of them can be disabled. The only one I've found that can't is the official T-mobile account app. But I just cleared the apps data, and never use it. I'm not logged in or anything, so it sits there idle.
Regarding "laggy", I can't really say. It works as well as Nougat did. And I think I can say the battery life is definitively better.

U firmware is just firmware without carrier bloat. You can flash any carrier on an unlocked phone. I provided the link to my thread with the official TMobile Oreo stock files just get Odin. https://forum.xda-developers.com/tm.../sm-g930t-official-stock-oreo-update-t3810449
hello. I had flashed my smg930a with smg930U firmware. after that everytime I restarted my mobile, it showed error " no network connection " sometimes it picked up network after a restart and sometimes it picked up network after weeks. Tried flashing smg930a firmware again but the error remains same. Now i flashed it with smg930t firmware hoping the error will end but it shows "searching" and I've no network connection.
any help will be great.
Hi, there's bloatware and it's mildly annoying as is the t-mobile splash screen and sound effect. I'll switch bach to 930u when Oreo is available. You'll also have no data toggle swith in the shortcuts when you pull the screen down. However, I added mine using adb. You can also uninstall programs uing adb but I haven't. If anyone has the adb script for removing t-mobile apps I'd be greatful if they'd post it.

Call your network provider or carrier and see if they can change the settings or to make sure your data settings are set up right. Things like apn settings, network, etc.

What network SIM are you using? You kind of need to match the firmware with the carrier you are using, as it enable certain radios. That being said, the 930U should work universally. If it doesn't, then you probably didn't update or use the right APN settings to enable LTE. You'll have to do some online searching to look for the appropriate APN settings for your carrier, especially if you are using a firmware version that doesn't match your carrier.
