Hi guys
BIG problem arose
My desire 816 is A5_DWGL ...I flashed CM12 and Everything works fine except that the sim card is not detected, i changed network to 2G and does no help..Press #*06# the IMEI is null
Then i flash back to stock sense rom. the IMEIs are back too.
Is there any possible the i back IMEI from stock rom, and then flash into CM12 rom? or is there another way to get my IMEI back on CM12?
oh, i want to know why my IMEI is missing in this situation? Any explaination here will be grateful!!!
UPDATE:
I FOUND THAT MY BASEBAND VERSION IS UNKNOWN!!
HELP PLEASE !!!
After flashing CM-12, Both SIM are not working. Flashed stock L firmware but still problem is there... any solution?
Please I need help in my sgh-i317m canadian note2
I bought it used but for some reason cant detect my local network (Egyptian)
By some repaire in the service center changing sim card holder and usb scart
It worked and made calls but
It was on 4.4.2 and always hangs and restarts by itself..
So I played more and more in all available options roughly ?
So
I downgraded to 4.1.1 stock via odin but the surprise no imei and baseband unknown ?
My questions are:
1 how to know the original stock between those ?? And if the difference make this hang ??

2 how to restore "servicemode" menu to original one cause I think it is the reason why I have no service now with custom rom based on 4.4.2 with correct imei and proper baseband but cant detect my network ???
Please help ...
Also when connected to computer detected as alcatel cdma phone if I dont modified it from *#0808# menu to pda in all roms stock and custom.
How to reset that phone ?
Before flashing anything, does the imei match the label under the battery?
Often, the imei will not appear because the modem and bootloader are not compatible with the ROM.
How did you downgrade to 4.1.1? A stock 4.1.1 ROM from sammobile.com includes the bootloader and modem to ensure that the imei does not disappear.
Please Help !
I´m form Germany and got an SM-N920A from ebay with Android 6. It worked with an O2 simcard. It had no bloatware installed.
I had no ATT Logo by booting.... that was befor flashing nougat with odin.
Now i already have Android Nougat on the device, but can´t use the phone.
The wlan works, but in this ROM i have no symbol for the mobile data anymore.
i think the serialnumber also changed....
i tried to flash an other ROM, but with the same result.
Is there an chance to get connection/ use my sim, or to flash the original ROM without bloatware from ATT.
I hope there ist someone who solved the same problem.
Thx
Hello everyone!
I was flashing a custom rom and I realised that my sim card is not detected...
I tought that it was a problem with bootloader and modem so I flashed them and still, the sim wasn't recognised.
Then I went to the settings to check IMEI and baseband and it was unknown...
After many and many tries I still can't feagure out how to fix this...
I flashed it to a stock rom and the baseband is still unknown...
I changed the imei with xposed extension succesfully but the sim still doesn't work because of baseband.
Please help me... *I was stupid for not making a backup*

You made sure you flashed the right modem and bootloader for your model/carrier as different ones have different bandwidths.
Sent from my SM-A520W using XDA Labs
i had the same issue , you need to flash the same firmware that came with your device but all of it ap cp csc also for bootloader use one more recent because it isnt allowed to downgrade , (for example my phone had the xeo csc and flash cos to make 4g lte working in another country and carrier but lost imei and sim , to fix it i had to flash the second XEO firmware found on sammobile witch was the one the phone had when i bought it
Dear helpers,
I flashed my galaxy s9 with TWRP and tried to flash a rom with it.
The rom wasn't working and I had already performer a full wipe.
When installing another rom i found out that i lost my imei, baseband and my sim isn't detected anymore.
I already tried to flash stock from sammobile, but that doesnt work either.
Does anyone know the solution for my problem?
Kind regards
