Lost IMEI and baseband after flashing wrong stock firmware. - Samsung Galaxy S8 Questions and Answers

I have a Colombian S8 (SM-G950F), it was in 8.0 and it wouldn´t update so I tried flashing the new update. I didn't check the CSC, and flashed the wrong one. Now it doesn't read my sim card, and in the settings tab, the IMEI code says "unknown", it doesn't appear with the dialing code either. How can I fix this?

Flash with odin the firmware that your phone came with.
The stock Samsung firmware can be found here: http://www.sammobile.com/firmwares/database/SM-N9005/
March the last 4 characters of the csc and pda to the firmware. Download it, unzip it to get a tar.md5 file, flash the tar.md5 file in the PDA/AP box of Odin. I prefer Odin 3.07 for flashing back to stock.
Tried all those but no luck...
I coudnt register with the network after searching and selecting the network...
It says unable to connect try later... veryfew times it registered with very few sim cards yet no dialling tone etc.. finally comes again to the registration problem state.... any helps?
Wrong IMEI and wrong serial is that correct .
Have you restored your original backed up EFS folder ??

[help] galaxy s4 carrier locked after odin flash

i am using galaxy s4 for a year
it was not locked to any carrier
i updated to lollipop and didnt like it and then i flashed kitkat over lollipop
then i faced invalid imei issue
after many searches on google i found the solution of flashing rom and modem files will solve the issue
so i flashed few stock roms and few modems
now i got back my imei, my baseband version is correct
but when i check service mode *#0011#
it shows IMEI CERTI - FAIL
and it asks for sim unlock after every restart and cannot register to network
i guess that when i flashed few roms, one of those roms might be a carrier specific rom.
now how can i get rid of that, coz no carrier will give me unlock code because it was never locked to any carrier
Check the SIM unlocking thread in the General forum for added details, but in short, downgrade the modem to an Android 4.2.2 version using Odin, install RegionLock Away on the device, and run it. That will blow away the SIM lock so you can use your S4 again. Afterward, restore the existing modem.

Can anyone help? SIM not recognised

After unrooting my gt i9500 with stock rom 4.4.2 my sim is not recognised. (Insert SIM) is displayed. I rebooted several times but it is not fixed. can someone help...please???
can you check if you have imei and basseband by going : Settings, About Phone?
if you have baseband and imei then your sim card reader is broken, if you dont have those then you did not flashed correct files for your phone.
IMEI is null and baseband is unknown...can you help me further???
you need to flash the stock firmware from kies or you need the correct modem to flash via odin. search on xda for it.

SM-N9005 problem: How screwed Am I?

Hi I'm looking desperately for help with these 2 major isssues, any advice will be much appreciated.
I recently bought this phone SM-N9005 and worked perfectly until I realized my gps doesn't work properly. After a brief research I discovered a youtube guide with positive responses so I gave it a shot. =hC8jNb38gaY . This included ServideMod digging via *#9090# -> insert Q -> insert 0000 -> UE settings -> setting -> system -> NV rebuild -> ALL . After that my sim card was no more functional just as any other I then tried. So this is my first major problem:
1) INVALID SIM CARD The sim card was doing just fine before that and is still doing when put into other devices, but no matter which sim card I try the problem still persists. So I tried factory resets, loading different firmwares... which led to problem:
2) CAN'T LOAD DIFFERENT FIRMWARE I think I was doing all accordingly to guides but still can't force my phone with different firmware. I got it rooted, and everytime I try to use Odin it just gets stuck at "Complete write" fail or FAIL Auth.
The only firmware I could load into it was the early leak of loli 5.0 N9005XXUGBNL8 . I then tried several of them so I could use for example AryaMod (which gets always stuck shortly after start of the installation - i think because i cant load demanded firmware) but to no avail. The so far tried firmwares were the stock ones;
N9005XXUGBOJ6_N9005XEOGBOJ1_N9005XXUGBOJ1_HOME.tar
N9005ZSUGOH3_N9005OZSGOH3_N9005ZSUGOH3_HOME.tar
N9005XXUGBOI6_N9005ETLGBOA2_N9005XXUGBOH1_HOME.tar
N9005XXUGBOI6_N9005O2CGBOF2_N9005XXUGBOH1_HOME.tar
And the only working is the one mentioned above from early loli 5.0 leak : BL_N9005XXUGBNL8_CL3643614_QB3415922_REV00_user_low_ship_MULTI_CERT.tar, which I currently have. Any other attempt to load meets with the same failure. I tried different versions of Odin, starting them as admin, different usb ports, wiping before, rooting it but just can't load any other. : /
So finally I'd like to ask: Is there any way to revert damages I did by doing that ServiceMod thingy? To get rid of that INVALID SIM CARD notice? I'd like to do it myself if possible.
And secondly, why can't I get any other firmware working? Is it wrong choice of firmware not compatibile with my phone or I just overlooked something during installation?
If you reached it all the way here, thank you. Please share any advices you might have.
Oh btw this is from *#1234# if its of any help : AP: N9005XXUGBNL8 CP: N900PVPUEOC5
What is the model number in download mode? Does the imei in the phone match the imei on the label under the battery?
Looks like wrong firmware flashed .
N900PVPUEOC5

Click to expand...
Click to collapse
...Well this is odd, the model number is everywhere stated as N9005 but in download mode it's N900P !
The mei number matches but it's short of one last number. The mei in back has 14 digits and in system 15.
Hey,
I got the same issue a few months ago,
It was the "pin" behind the cover that didn't reach for the antenna on the other side
This crappy video helped me a lot
https://www.youtube.com/watch?v=iUsXU28IDdM
Update: I just discovered I can only install the N900P firmware so right now the both AP and CP is N900PVPUEOK2.
But the firmware selection for 900P seems rather limited to USA region. Back then I had czech (maybe european version with czech language?) version.
Info about phone now says my phone is N900P even though my phone is 9005 and so was the firmware for it.

Basabeband corrupted

Hi guys, i have a xt1626.
And for some reason last night I lost my network signal and SIM 2 status.
Well... I made a factory reset and flashed lastest stock rom (december 2017).
But it still not work.
SIM 1 is working IMEI is correct. but no signal. Only showing "No Service". SIM 2 is missing.
When I see baseband it shows lastest baseband but not with "DSTV RET_BR..." on final. It show "DFLT_FSG".
I flash modem, install others rom (custom) but nothing works.
There is a chance that make it working again?
Are you sure you have flashed the correct version of stock rom.??? This happened to me only when I flashed the ROM for another variant!
I flash this one: https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138
After some google search I found the problem.
The mobile radio is not turning on. Like if the phone still in airplane mode.
i don't know what i have to do. No looks like HW problem cause sim card is recognized
There is a place wich i found specific firmware for xt1626?
firmware.center only have universal firmware.
That link doesn't have the firmware for 1626.. there was a file factory link that had all the variants stock ROMs.. So if you find any nougat version you can flash that barring bootloader and gpt.bin as downgrading them will result in a brick! And then take OTA!
