model different to firmware

Hey All,
Just bought a second hand s6 g920 and the back of the phone says g920F but the software on it says G920p. How can this even happen and how can i fix it?
i'd rather have g920F firmware as that is the international one and has more xda community support.
thanks in advance

Same problem... can anyone help?

DOWNLOAD FIRMWARE OF SM-G920F from sammobile.com and flash it thorugh odian. it is quite easy.

most likely the previous owner has damaged the phone and back glass was replaced.

Put phone in download mode anf check the model number (it cannot be changed ).. Its easy .. Just use a little your brain...

when you start phone in download moder, look on top there will be written model no of your phone. check this is original model of you phone. may be you phone board has been changed.

well... flashed stock g920p firmware through odin, it boots quite fine but with changed imei (it shows s5 when i search imei online... network/data works fine)... g920f firmware flash fails.... also samsung s/n is 000000... restoring efs also doesnt help... flashed back to the software with which it came.. imei back to g920f... s/n still 00000... bootloader g920p... recovery g920p... kernel g920p... baseband g920f... build g920f... anyone???

Flashing ROM of the same Model No. but different PDA/CSC. Is it safe?

I want to flash my Smart-locked Philippine Variant SM-G920F with the France Firmware SM-G920F. Is it safe?

should be maximum if odin fails flash the stock philipino version again

Hi,
As long as they are the same model you won't have any problems. Worst case scenario download the stock ROM for your country as well and flash it back.
All the best,

I have 920f XEF i flashed UK firemware and all ok then after 48h my phone restarted now i lost imei ! Now i learned in hard way never flash other roms on a phone because thats why they made difrent ROMs difrent models...i didnt make backup now i fixed it with octoplus(10bucks) with difrent imei RDK binary missed up signal drops time to time

Either call the carrier for code or try flashing back the original Rom.

*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.

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.

Samsung Galaxy S7 SM-G930F - No Network (SIM - CARD)

Hello Guys, this forum is my last hope. I have a problem with my S7 (DBT Germany), I think after flashing an older stock rom and going back to newest, something happened that my phone doesn't detect any sim cards anymore. If I type *#06# , it only shows the SN Number, no IMEI. WIFI still works without problem, but I can not use my sim card anymore, so it's pretty useless now :crying:
The sim card works on another devices, so it's for sure a problem with my s7, I might have messed up something. What do you think is here the problem and how can I solve it? Any help is much appreciated, I really hope to fix this because my phone is only 2 weeks old.
I currently have the latest Firmware for DBT from updato, (December 14, 2017 for Android 7.0)
IMEI = unknown
SIM Card status: Not avaliable

Have you tried a stock ROM from sammobile.com? Updato and sammobile.com should have the same ROM but maybe there is a difference between the 2?
Did you confirm that the phone is running the latest modem?

I did not try sammobile because updato and sammobile were the same firmware. Sammobile does have a newer firmware from 28/01 but it says I need to join in order to download.
Is there a way I can fix a damaged/corrupted EFS ? My phone is pretty useless now without sim card detection

Sorry, I know of no way to fix imei issue if a combination of Odin and a stock ROM does not work. You may have to take it to a cell repair shop that can force flash the ROM and EFS using hardware like an octopus box: https://octopusbox.com/eng/features/models

Hey, flashing a Stock Rom with Odin + Root works for me with no problem, how can I flash my EFS? I do know my S/N and IMEI number..

Do you have an EFS backup? If yes, this may help: https://forum.xda-developers.com/showpost.php?p=72355071&postcount=3

I don't have an EFS backup. Any chance without a backup? I do know my S/N and IMEI...

You would need a way to recreate the contents of the folder. Unfortunately, I'm not sure how to create the contents.
Maybe this will help: https://forum.xda-developers.com/s7-edge/how-to/guide-how-to-fix-check-drk-imei-issues-t3379516

Hey, I have finally found the solution and my sim card is working again :victory:
It really was just that the firmware was 1 version older.. I downloaded the latest DBT Firmware from samsung-updates (Build Date: 15/01/2018)
Put Bootloader to BL , AP to AP , CP to CP , CSC (not Home_CSC!) to CSC , flashed it and finally my IMEI etc. is back.
Thank you for taking your time trying to help me

Congratulations on your success

[Fixed] My SM-G955U Has No IMEI or Baseband

EDIT:
I was able to fix it! I had to install a custom ROM to obtain root and delete my EFS partition.
So, here is a bit of a story I will try to keep short.
I went to Vietnam and bought a S8+ from there.
It was a US S8+ from Sprint.
I used it fine there but when I came back to states I tried to put my Verizon sim in and it doesn't work.
I don't get any signal. But I am able to see Baseband and IMEI.
So, I tried to use Odin and flash one of the SM-G955U1 Firmware.
Now, my phone is weird and out with no Baseband or IMEI.
So I try to flash back to firmware it was on.
Same thing.
Any ideas why my S8+ is like this?

If you can get into recovery, what info are in those details?

What happens if you restore from the OEM function?

Try downloading custom recovery and flashing a custom rom. You will lose samsung pay but you might have a working phone it's a chance I would take if it was me. Your baseband is messed up try just flashing your carrier baseband . These are just ideas good luck

If flashing a custom ROM will fix your phone then so will downloading latest official Samsung ROM and flashing via latest Odin .
The second option above would be the best to try unless you're happy to have a custom rom and lose Samsung pay and anything that relies on Knox being functional

Update on the post, I sent it into Samsung. I should hear word soon if they can fix it and how much if anything.

Jtag dead phone to life and rewrite IMEI
First of all my phone is the s8+ G955fd, but I am sure that the people that helped me can help most Samsung owners with bricked phones.
My phone ended up being stuck on the first boot screen, I couldn't get into recovery or download mode. I installed TWRP and after that I lost my IMEI numbers( dual sim), so I tried to reflash stock and thats when i became bricked. I searched someone to help and found reference to the Fonefunshop in England. I sent it there and they said that the eMMC chip was bad. I searched for someone who could write to it or put a new one on the motherboard . I found A2Z cellular in Ottawa Canada. They used jtag to restore it to stock and they told me that the Fonefunshop had not opened the phone which is necessary to use jtag as they claimed, so avoid them.
The phone was now back doing everything it should except the IMEI's were null like before. I gave them the original IMEI's and the phone is working like new.
If your Samsung is bricked these guys can probably fix it and it won't cost much to find out.

the SM-G955U has a locked bootloader, so people should not be telling you to flash a custom recovery or custom ROMs. there is only one way to get root on this phone, through the samfail exploit, and safestrap is the only working recovery. I don't believe it supports CDMA networks but I'm not 100% sure on that. I have this device and I'm only aware of GSM carriers using it.

Just an update on this issue. I still don't have a working Baseband or IMEI. Any clues?

I was able to fix it! I had to install a custom ROM to obtain root and delete my EFS partition via ADB.

Be very careful with doing that. It can cause the EFS (the partition that controls IMEI, Mac and a few other things) to be completely corrupted. Which will cause the device to be useless without fixing it.
Now a little heads up. As messing with the IMEI is illegal in many countries (the US being one of them) There are only 2 ways to fix an IMEI issue allowed on XDA.
1. Restore the backed up EFS partition
2. Return it to the OEM to be repaired.

What did you do after you deleted EFS? I can delete in Combination but I dont get the IMEI number back.

Please I need all XDA members assist ,because of I mistake delete EFS with combination file on my G955U VZW , I have null imei number, then I repair it by flash qcn with z3x Samsung tool , but still I have IMEI number but emergency call only is still display without service ,
