now the sim card works in other phones and when I remove it the device registers it is SIM CARD REMOVED but when I put it back in nothing happpens, and mobile networks settings is gone
*I started in stock 5.1.1 (MADE NANDROID BACKUP OF EVERYTHING INCLUDING EFS) and flashed twrp via odin > (everything still working)
*flashed XtreStoLite 2.4 (5.1.1) via twrp > (everything still working)
after several months
*flashed new 6.0.1 bootloader and modem via odin and tried to flash XtreStoLite 3.0 (6.0.1) via twrp > got stuck in bootloop...
*used smart switch to go back to stock 6.0.1> Everthing was OK until about a month later the phone suddenly restarted and doesn't recognize the sim card
* I tried factory reset
* I tried samsung but they gave it back saying I've tripped my knox flag
*I flashed 6.0.1 XtreStoLite bootloader, modem and TWRP again via odin
*I flashed XteStoLite 3.3.1 (6.0.1)
*I tried restoring from the first nandroid (stock 5.1.1 from the begining) and got stuck in bootloop again.
*reflashed XtreStoLite 3.3.1 (6.0.1) and tried restoring only the efs. still doesn't work.

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.

New g955u won't connect to Verizon

I'm about ready to throw this phone out the window, and hoping someone here can help me out...
My wife ordered a never used g955u off of ebay. It came with Oreo installed. It had the CRE9 firmware installed. We are on Page Plus (Verizon reseller). We put in her SIM card, went through setup, but we are not able to make phone calls. The SIM card works fine on her old phone. I reset the network settings to no avail.
I did a network search and selected Verizon Wireless, but it times out and gives the error :
No Service
Selected network (Verizon Wireless) not available
I talked to Page Plus, and everything looks fine on their end, they say it's something in the phone.
I suspect it's something in the radio settings, but I'm locked out of the service menu. I factory reset the phone, and that didn't fix it either.
I've been down several rabbit holes since then.
I tried to follow the steps in this thread: https://forum.xda-developers.com/galaxy-s8+/how-to/carrier-switch-snapdragon-t3615680 hoping that if they can make non-verizon phones work on verizon, then it can make a verizon phone work on verizon. I also tried to root the phone using this thread: https://forum.xda-developers.com/ga...root-g955u-g955u1-snapdragon-sampwnd-t3658911 hoping to get access to the service menu.
But evertime I tried to flash any of the necessary binaries, I got Fail! (auth) and the phone gave the error:
sw rev check fail : [boot]Fused 3 > Binary 1
or
sw rev check fail : [boot]Fused 2 > Binary 1
Turns out, you can't downgrade. And all the binaries in the tutorials are now downgrades.
Somehow in all this, I managed to flash the phone to CRD4. I tried flashing back to CRE9, but regular Odin fails without telling me what the error is, and Comsy Odin gives a model dismatch fail.
I tried connecting the phone to Kies, but it gives me the error "only the device owner can connect to kies" even though I'm running Kies as administrator.
I've ordered a new SIM card from PP, just in case that fixes it, but I'm losing hope here. If anyone can help me out here, I'd really appreciate it. If there's anymore information you need, let me know and I'll post it.

Yeah, that's what I had figured out. I'm still not sure what direction I need to go in to find a fix for this.

So I know Odin 3.13 at least. But other than that with Oreo I don't know

I wanted to stop by and mention I am having nearly the identical issues. I bought a used Verizon Galaxy S8 from somebody today, and even ensured that the IMEI was supported by Page Plus beforehand. I tried using an existing, working SIM card of mine from Page Plus but found that it did not work automatically as it should have. After going through four customer service representatives, I was told that my phone is somehow not compatible. Still, I think I may have a slightly different situation going on... I was told it would not work because there is no "LTE/CDMA" option in the "Network Mode" setting. Instead, upon inserting the existing SIM into the new phone, my Network Mode setting only has access to "LTE/3G/2G (auto connect)", "3G/2G (auto connect)", "3g Only", "2G Only" options.
When I put the SIM back into my working phone, it gives me the correct network options. For some reason, this new phone is not allowing me to connect to the Verizon network at all.
You've taken a lot more steps than I have... I figured it could be an issue with Android Oreo, but I am really not looking to delve into the degrading process. I will also order a new SIM and see if that magically fixes things, but it's starting to look like a lost cause.
Let me know if you figure something out - you are the ONLY person online I have found with my identical (or near identical) issues. If you happen to know any way around the exact issue I'm having with the Network Mode, that would be insanely cool.

Note 9 (SM-N960F Exynos) incorrect IMEI

Disclaimer: So its not a stolen phone, prior owner was just being nasty. I bought the phone from a 2nd hand shop (Cash Crusaders, Kathu, South Africa), where they told me that a lady sold the phone to them, came back after 3 months and wanted to buy it back for the same price (they guarantee buybacks for 1 month), they refused to sell it back to her at selling price, so she went and had the phone blocked. They went through the process of unbricking it through the ISPs, but in the meantime also got repair shops to try and fix it... They changed the IMEI number... So I bought the phone, fully functional, did a factory reset, saw that it had OEM unlocked and figured it was the cause for the biometrics not working, turned that on and thats where my mission started. OEM locked, custom firmware detected... Used Odin to flash on stock firmware (from Frija), got the phone functional, but emergency calls only and no cellular. I have tried rooting and using console, I have tried changing it in the EFS file, I have tried changing it via ADB Fastboot, via dialer (does nothing even with Google Dialer Framework V5)) no dice, it keeps the incorrect IMEI. I have looked up the IMEI on IMEI.info and its clean, so I take it they managed to get it unblacklisted, which is why I want to get the original IMEI back.
What I would like help with is does anyone know how exactly I can change the IMEI number on my phone (Rooted with Magisk and TWRP, but eXposed framework is finnicky and doesnt register properly, even through I installed the RIRU (V23) and RIRU EdXposed (Canary, both Sandhook and YAHFA on seperate occasions) packages via Magisk (V21.1 and V8.0.3 for manager) as per instructions.
P.S. I am a student on a tight budget, so I would prefer to do it on the cheap/free and I live in Namibia, so sending it to Samsung isnt quite an option.

Also please let me know if there is any info, logs, etc. I can attach that might help.

I have my receipt and they have theirs. So by all means verify the IMEI yourself 356630093456642.

Thing is phone got cleared. Original IMEI is clean, which is why I wanna reset it back to it, only problem is they seem to have used a flash-kit to change it in the recovery partitions too (bricked the damn thing when I recovered it (accidentally turned OEM lock on...), I've tried everything down to loading the engineering combination file (interesting though, its android 8.1, which shouldn't actually be possible to do from Android 10) on it and trying through there, no dice. Also asked local repair shops if any of them have a flash kit, none have 1... So I'm stuck at this point, cant even do the normal 'pay a repair shop to fix it for you' method.

Question Samsung S21 VZN need unlocked or converted to ATT. Tried odin.. Maybe I am an idiot.

Hello.
Got a free phone from a buddy S21 5G. I am wanting to swap it for the S10* 1tb I gave my wife to use it was a bit expensive. So I'd rather ti go back in the box.
Popped the sim in it, it works makes calls sometimes, sometimes not. Texts seem to always work, I am currently on ATT I would prefer to have that firmware as I live in the stick with ho cell service. ATT has wifi calling which is pretty much a necessity here.
So what exactly do I need to do to get this off the VZN fir

Hello. Could you all provide me the links for what I need? Found a link that had a patched Odin plus the firmware. I installed in booted how I was suppose to. Tried to install in and it errored out. Also. I do not know what file to select for the user data selection, I do not mind deleting all data as it 8s hacked up and can put ti back with smart switch.

Hello, did you manage to flash the phone?, I'm stuck with a similar case, mine is a factory unlocked unit from Verizon, it turns out that even if it is factory unlocked, is locked after a few minutes by verizon, I have tried everything to get rid of the VZW firmware but it seems that Verizon locks the bootloader so I can't flash it (it passes om odin and everything but the firmware doesn't change)
I even paid SamKEY credits to change the CSC but it didn't change either.

Phone won't boot

So if I do the soft reset by holding volume down and power button it just restarts and comes to that brick download screen. It's all blue with a white arrow that says dont move away from target (something like that). If I continue to hold that in it just loops that cycle. if I manage to get it into recovery (its hard to time it with it immediately restarting) it will bring up the android guy and flash "error" under it and immediately restart. If I'm still holding in the recovery command buttons it continues that loop. It does show the Samsung screen at the very beginning. If I put it on a slower charge (say from a 12vdc car plug) it will show a black screen with red letters stating an error fail to read bota partition.
I am a complete noob with tech. So keep that in mind. I tried offering as much info as I can. I have some pics and a vid.

looks like failed update, vbmeta is older than boot. download stock ROM according to your region code (CSC) install usb drivers and flash from Odin3 in proper slots.

I am very noob. Is there much info on how to do this somewhere you can link me? I am very sure this did happen when the phone tried to update (I kept postponing it) while in my pocket during class.
Will it be able to install without boot up? From what I'm understanding at this point the usb just recognizes the phone as a battery. The thing I'm trying to do is recover my data. I could care less about the phone itself

This seems to be pretty common with Samsung updates. Throughout time. I've had a friend that manages a T-Mobile tell me that after an update on two of his phones it came up with a moisture detected in charging port error. I think he said a soft reset fixed those.
Downloading the csc patch just fixes the firmware and would keep my data intact?
