Modem flashing - Device Repair

In many custom roms of Huawei Ascen G700-U10, after flashing the custom roms, due to BASEBAND unknown error, sims are not working.
Many people ask to take the backup of original modem.img from stock rom.
Please let me know how to flash the modem.img to device after flashing the custom rom..

[Q] question regarding modem for india

i recently bought a galaxy note in india. i want to flash a kitkat rom such as asylum omni. do i have to flash a modem for india seperately after flashing the rom? i once flashed a rom in my galaxy s 2 and it didnt get any network reception after that,even after flashing many modems. i am realy afraid that i might render my note useless if i flash a rom again.. please advise.. thanks
The AOSP/CM roms you want to flash doesnot come with a modem. So it utilizes the modem installed previously. If you are on the DDLSC rom then the modem you should have is DDLS6. After flashing Kitkat, it will remain DDLSC unless changed manually.
Just after rooting, first thing you should do is backup EFS.

[HELP] unknown IMEI and unknown baseband

Hello devs
I am having s3 GT-I9305 LTE 2GB RAM qualcomm based.

I don't know what happened but suddenly the phone just got switched off when I on the blocking mode and after that there is unknown IMEI and baseband.
I tried to flash diffrent modem but was of no use.
Had tried many ways but was of no use....
Can anyone please suggest me what should I do

Does installing stock rom again will bring it back or there is other way
Please help :'(

First you may try to reinstall Stock Rom using Odin.

Bro I tried flashing persues kernel cause somewhere I have read that by flashing persues kernel you can get the phone back to normal.
So I flashed the kernel and after that it showed me baseband number but imei was showing me only 0 nothing else.
I updated the phone to 4.4.4 so check it will work or not but was of no use.
Can u help me by giving me the link of a complete stock with all the file for GT-I9305 uk version.
Hi,Mustakim_456,I would recommend you first to try this method-flash Param.bin from this thread:http://forum.xda-developers.com/gal...warning-guide-backup-restore-imei-nv-t1946915
It's simple and quick,using Odin.Good look.If this doesn`t work, try to flash ROM stock from here:http://samsung-updates.com/device/?id=GT-I9305
You will find versions 4.1.2;4.3 and 4.4.4.

Help! No imei.

Help!
I did not do a backup IMEI and now does not work network, no IMEI? Is it possible to do something?
which rom / which kernel flashed before lost your imei
because if your problem kernel related, little change but maybe your new kernel cannot read your efs info. if this; you can flash stock rom with odin.
But if you lost your imei when flash a stock rom with odin (i did once with my old note 2!!) then try to flash custom rom (DrKetan recomended) and his stock modified kernel.
i hope you fix your problem.
I did root, after some phone application hangs. After uploading new software was no longer the network and IMEI. I tried to upload the rom dr. Ketana and its kernel. Next the same.
Try to take a modem.bin from odin and flash it.
Make sure the Odin is your model.
try original stock rom via odin
Thanks helped to upload the original rom for Tunisia

Help with stock n920g flashing process

Hi, im in a nightmare for about 2 weeks trying to flash a stock rom in my n920g.
I have to flash a stock rom cause i was trying to sell my phone, i tried like 10 different roms, when i flash N920GDDU2BPC4 rom with 4 files theres no problem only that theres no spanish in there (and i need it) so i tried to flash an argentina n920g stock rom from sammobile N920GUBS3BPI2 and i get several errors in odin, with modem, cache, etc, tried erasing those files but then i go to a black screen with dm verification issues, at this point i dont know what to do i just need a stock rom with spanish language...pls help me im getting mad with this issue, never happened me before, both roms r MM 6.0.1, my only hope is to find a stock rom n920g with spanish but flashable trough TWRP but WITHOUT ROOT.
I used system info app from play store and it seems my n920g is a mess with modem from india, bootlader for argetina, rom from Z version, etc, now i cant flash any n920g rom, i think is cause of the bootloader but i cant flash another bootloader cause i get a fail message in odin, no idea what to do now....i just want to get a stock rom but now it seems impossible.

Question about updating from Lollipop to Marshmallow

So I've decided to move on from the TekHD rom to maybe a newer version rom (marshmallow). However, I'm confused about the process. Would I just use Odin and flash all appropriate files to be on the latest modem and basebands for marshmallow then flash the rom I want? I'm already rooted right now, would I need to reroot during the process (I.e; flashing supersu script)?
Hope this helps
