Did I brick my S4 from Bell by installing wrong Modem? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hi,
I installed an ME2 modem for the GT-9505 by mistake and now I cannot get cell phone signal. I did it using Modem 2 in Odin Mobile. Is it possible to fix this?

Just find and flash your original modem. You should be fine

on CM9 flashing UGJK3 modem = no connection

My phone was originally a Bell Vibrant (i9000m Canadian) which I flashed to CM9. The signal drop has been significant though (and I see other i9000 users using the UGJK3 modem. When I flash it using Odin, my phone won't connect (never gets signal).
So, how do I flash a modem correctly? Should I be wiping/factory reset? What's the process?
Search for siky's thread. And flash trough cwm.

Found the thread. Can I flash a JVT modem if my baseband is XXJVT?
Why would you flash jvt when you already have jvt...
Baseband=modem=radio

Stock modem for our bell/virgin mobile phones is KG3. Use it, works perfect for me.

Unlocking help needed

Hi all first of all the phone is locked to EE I tried the *#0011# method and at first I couldn't get into the right menu which I've found out to be the modem that is installed needs to be me2 or older.
So I have flashed the me2 modem and was able to get the menu to turn the lock off but I can't get to the next menu to save the setting ?
So do I need to flash an older firmware version to match the older modem? To get the menu to appear?
I'm thinking to flash a o2 stock firmware to see if that works?
Thanks for any advice

Unlocked AT&T Galaxy S4 not working properly

My fried bought a Galaxy S4 from AT&T when he was in US. While leaving the country he bought an unlock code from AT&T and unlocked the phone using the same in India. His phone was working fine initially. Then sudden signal loss started to occur and need to restart the phone to get the signal back. Tried using different Indian carriers and the same issue continued. Will I be able to solve this issue by flashing a custom rom into his phone? Do I need to take care of anything else, like the modem firmware or something. Attaching a screen shot of his phone details. Please help guys..

You could try reflashing the same MDL firmware first. If that doesn't work, then install TWRP and try the different flashable modems.

Thank you for the reply.. However we have already tried a factory reset.. Will it be a problem if I flash the modem firmware available in the Indian Galaxy S4?? The Indian version comes with an exynos octa processor instead of the Qualcomm one..

Doing a factory reset is different from reflashing the firmware. I don't think the other modems would work, but I'm not entirely sure. If they're recovery zips you could try, but if they're ODIN files it definitely won't work.

I have tried reflashing the phone with Odin. The device now has the latest Android 4.4.2 firmware from AT&T. It seemed to work fine after flashing. We got the network and were able to make calls as well. However after sometime the signal got cutoff itself. Tried flashing again, the same thing happens. Any other suggestions??

flashed the ne4 and the nc2 modems
didn't work
any other ideas?
Are you using an Nordic/Scandinavian variant? - if so, flash back to stock. There is some issues with them particular variants and has been since 4.4.2. - Even if you aren't I'd go back to 100% stock to be 100% sure first to determine if it may be a hardware issue also.
