No imei after flashing a costum rom - Samsung Galaxy S7 Questions and Answers

Hello everyone
I tried to flash the Batman 1.5.0 rom and the Lineage 14 rom in my s7 G930F but i only can get a valid imei when i use a stock rom.
I used the batman rom for like 2 months and everything worked fine but now i cant use a costum rom anymore!
Does anyone knows how to fix this issue? Ty a lot

Cant flash to older versions. Grab the latest stock and flash yo get it back.
Wait for custom to be updated with even newer base then flash it

Ok i'll try it ty

Did it work?

Simple
Fixed!!!!
FIRST!!
1. FLASH BL AND CP from the stock firmaware!!
2. go to recovery and flash BATMAN ROM or another costum rom
3. When you install Batman rom just choose : KEEP CURENT MODEM AND BOOTLOADER!!! If you update that 2, the imei and the signal from the phone not working anymore.!!!
4. Just be sure again, flash BL and CP first from the stock rom! And keep the bootloader and modem don,t update from another rom!!!

5.1.1 For N910H Only​
Hi Every one ... I'd Like to share my little experience on Installing Stock Rom 5.1.1 And Rooting + Custom Kernel
1- Download Odin3 v3.10.7
2 - Download 5.1.1 Firmware FOR N910H From Here , Extract it and Start Odin then select [ AP ] , select the extracted .md file
3- You must Select Nand Erease All From Odin options before flashing
4- Press start
5 - After Flashing and your phone starts normally continue with the setup wizard
6 - Download ( I Prefer ) TWRP 2.8.7.0 Custom Recovery twrp-2.8.7.0-treltexx.img.tar
7 - Flash the recovery with Odin again
8 - Restart your phone in Recovery mode
9 - install GoogyMax 2.0 Or Latest Talexop Kernel or Spacex Kernel
10 - Now your have offical stock rom 5.1.1 for N910H with fullroot with custom kernel ,
N910H Bootloader and modem Thanks for @liquidguru for sharing the link
Flashable Modems for 910H version Here - Flash in cwm or twrp recovery. No wipes needed
now you can flash other custom rom based on 5.1.1 like RulingLite or E-TEAM DN5
you can use 910c 5.1.1 kernels it also works on 910h i use it and it works
And maybe Enjoy flashable 300+ font HERE
I hope this was useful, i just collect what you needs in one place, thanks
Flash recovery + custom rom ( ie n910c ) + n910h bootloader.
If you want to use custom rom ( n910c rom without modem ).
No need to go through all those steps to get custom rom.

Function of bootloaders you can google it,
you should install the proper Bootloader for your phone version
you can install bootloader via Odin
download link of bootloader and Odin mentioned above in the OP

after flashing 5.1.1 Stock Rom , flash the recovery as i mentioned in OP using ODIN too, then u can flash any custom ROM even from n910c
but in case of 910c you should flash n910H modem and also you have the link in OP
by the way i test to use 5.0.x n910h modem with 5.1.1 and it works

Maystro be aware that if the custom ROM they are referring is a 5.0.x, they may have to reflash a stock 5.0.1 ROM or bootloader to make it work. Users are having problems reversing from 5.1.1 to 5.0.x because of bootloaders.

ROM didn't opened because it might have got corrupted while downloading try redownloading it, By the way ROM isn't opened its flashed by any custom recovery.......
In case of stock ROM did you tried Odin and flashed the full zip (tar) file ?

If you don't get OTA, use smart switch or odin. Smart switch is better. It could automatically decides which firmware is the most suitable for the phone. All you need is model number and serial number.

When I say update is like update a dead rom, like XtreStoLite ^^' not an official one. Thanks for your answer anyway
If you are already on a custom rom then most likely you have a custom recovery such as twrp. You can download a rom put it on storage and flash. I always do a full wipe when going from one rom to another (this is essentially a factory reset, so you will lose settings and apps/messages amd so on) but you can do a dirty flash where you don't need to wipe but there are possibilities of issues occurring. If you are on a 5.1.1 rom and whish to flash a 6.0.1 rom then make sure you update your bootloader to a 6.0.1 one.

The point here isn't to change rom by update. I have XtreStoLite I have modded it to be faster but the Base is old. I ask how to update the Base of a custom rom without change anything.
You would have to build the rom from scratch with updated base, as far as I know there's no other way.

[Q]how to flash OTA package with twrp?

i have new recovery twrp(decryption support) installed and also patched boot.img with root, now i want to flash update_data_hw_full package and an ota update.zip package, which is stock firmware. can i flash it with patched boot? or do i need to flash stock boot.img first? and will flashing this firmware with twrp work? bcz it is an OTA package
No, TWRP can't flash stock Huawei packages, you'll need the stock recovery.
You may also need stock boot.img, not sure, I don't use it.
Once i flashed those nougat files with twrp and its all working good. But thats an old ver of MM twrp..
Haven't tried the new one.

Help updating my rooted device.

This is what is installed on my device: TWRP 3.0.2-3 / android 6.01 (I THINK it's a bit modified rom) / SM-G930FD
I rooted asap I bought it few years ago, I want to update to the latest Nougat version 7.0.0 (I think the 7.1.2 is not officially released, right?)
All I need is stock (slightly modified is also ok) + root and don't mind formatting it to start from the scratch.
What are my options and/or what should I do? Thanks for reading!
Flash the latest stock ROM with Odin, then root.

Thanks for the reply.
Can't the TWRP do the same thing? If I flash using the Odin, will I lose the TWRP?
You need to use Odin to flash a stock ROM which will cause you to lose root and twrp.

Could you tell me which ones should I use? What do you think about the smartswtich?

I recommend matching the ROM to the original carrier.

It's an international unlocked version, does it have a "carrier"? How do I find it? I'm located in Japan and imported this phone.
You can install the Samsung Phone Info app from the Play Store to find out the csc and match that to the ROM.
