[Q] No signal after rom update G900M - Galaxy S 5 Q&A, Help & Troubleshooting

Hello I am new here so bare with me about noobie questions
I have a galaxy s5 g900m which was on stock 4.4.2 KITKAT with root
So i wanted to update to lollipop so I downloaded a stock rom from sammobile with lolipop and flashed with ODIN
Phone boots up fine everything works except for 1 thing
There is no signal- meaning that it shows a signal for a few seconds and losses connection repeat all the time
Tried reflashing and wiping entire phone from recovery with no help
Before the rom flash It worked flawlessly!
Any ideas?
Need a solution fast!
Thank you

I had this problem as well when I installed Lollipop on my rooted G900F (BTU), I solved it by doing a Factory rest then re-installing the Lillipop rom using Odin and doing the Factory reset again after the second install.
It has been fine ever since

[Q] Samsung S4 SGH-i337m - Can I root it normally

Hey people of XDA,
It's my first time posting so forgive me if its a repeat or dumb question but here goes my story :
I bought a used S4 that was rooted + aws enabled. It was working fine until one day it got stuck on the Samsung logo during boot. I tried clearing cache and factory resetting from the recovery but that didnt work. So I proceeded to reverting the phone to the stock rom with odin, which I got from Android rootz ( Google telus s4 stock rom, its the first link ).
So that worked, the phone booted its 4.2.2 but , no Wifi and no sound no AWS. My question are :
- Why arent the wifi and sound working if it was stock ?
- can I root my S4 following the steps in this thread : (http://forum.xda-developers.com/showthread.php?t=2293800 ) ?
- does it matter which version of Android im on ? for instance, I was thinking about installing the stock kikat for telus before rooting ?
- Does it matter if i use odin 1.85 vs newer versions
THANKSSS

1. I would install 4.4.2
2. If it wont work with odin1.85 use the 3.09 version
3. Install philz touch recovery and select "clean to install a new rom" so everything will be cleaned and the wifi should work fine after flash with odin
4. root it with www.towelroot.com
5. I hope I answered all your questions
Hey,
I really appreciate your help...i just started all this stuff yesterday so lm going to look into philz touch recovery. Also I think I know how to root using odin so im just going to do that once my phone starts working ( unless that doesnt work on 4.4.2 ? )
However, Right now can i just use odin to add in kit kat stock rom for telus ( or any other stock rom for that matter - maybe the one i used was bad )? I honestly want to worry about rooting and AWS after getting the phone fully functional
Thanks again i really appreciate your help

[Q] S-pen stopped working

Hi all!
since yesterday my S-pen stopped working when i resetted my phone (i was on a custom rom then)
I crashed in to a bootloop for 3 days (i just used my backup phone because i didnt had any time to fix it)
After 3 days it randomly booted the phone and i succesfully restored my phone to factory settings (still on the custom rom tho)
after it was resetted my S-pen stopped working and it did nothing on the screen.... It is still being recognized when i pull out the S-pen but i can't use it on the screen.
So i just restored it to a stock 4.4.2 kitkat rom (UK version) but still without luck.... the S-pen is not working
Anybody that knows what the problem is? the custom rom was X-note and before the restore my s-pen just worked fine...
Can someone please help me?

downgrade official lollipop to official kitkat 4.4?

Has anyone successfully downgrade official lollipop 5.0 to official kitkat 4.4? How? Is it safe to do it? Please help [emoji38]
I am quite sure a lot of people have gone back to KitKat from Lollipop, including me. In the course of last one week I have flashed Lollipop at least six times and came back to KK each time. So yes, downgrading is absolutely problem free.
Thank you devil

I would save all your personal data to the PC desktop. Wipe everything ( twice ), and then do a factory reset. Now odin flash back to whatever version of KK OS you want to run. Make sure you use a complete stock .tar firmware ( system/modem/bootloader ) from xda or sammoblie has them. Once you flash back to stock, odin flash it again to make sure everything installs. Then root and reinstall your data. If you do a lot of flashing from lollipop to KK, your going to have to take out the trash every once in while for lack of better words. I do a lot of flashing and end going back to bone stock about once a week, this helps from corrupting vital programs like efs. So in other words there is no magic pill. For more info click my signature the versions of KK might be different but the procedure is the same.

Downgrading official lollipop (XEO) to Kitkat (BTU)
Hello Note 3 users. I would like to ask (maybe someone already tried) to downgrade official (not leaked one with bugs as was mentioned) lollipop to kitkat? My phone originally had BTU kitkat, but I wanted to test lollipop and downloaded one from sammobile (XEO). Flashed as it was described in Sammobile website, everything went well. Rom is working well, but gps takes ages to fix, and only a few satellites. They are always lost while driving. Because of this reason I would like to come back to BTU kitkat again (get gps working normally again and receive future OTA updates). Can I flash Kitkat like it's described in sammobile? Wouldn't I mess the bootloader or something? (XEO Lollipop to BTU Kitkat)
I successfully downgraded from Samsung's official 5.0 to 4.4.2. I wiped the phone first in recovery. Then flashed using Odin version 3.09.
My Note 3 is an SM-N9005.
After receiving the 5.0 update yesterday for my Note 3 (product code XSI) and not liking it very much I will be downgrading again. At least the newer build in the XSI ROM seems more stable than the BTU ROM I tried before but I will still downgrade. One of my favourite apps, Delayed Lock, isn't working on 5.0.

Can't record video on lollipop touchwiz rom

Hi guys
I came from jamal rom v40 s5 port for note 3 on android 4.4.2 and i tried android lollipop resurrection remix and it was great but i decided to return to touchwiz to try s6 port.. i installed it and everything worked fine, except for recording video: when i tried my phone reboot, everytime and also with other application like whatsapp or other camera application.. i can take photos but not video. I tried other rom 5.0 touchwiz and the result is the same, but with aosp rom it works.
what can i do? My friend has the same rom i want to install (dark lord s6 port) and he can take videos so i know that it's my phone's problem. how can i resolve? I want you to know that i can't take video with every touchwiz lollipop rom and every kernel.. i can't understand why
please help me
So I solved it by:
Using Odin 3.11.1
I have already tried Factory reset, wipe cache, wipe dalvik, flashed the latest stock Lolipop or older lollipop with ODin and nothing solved the problem.
So I tried to flash the latest stock lolipop with Odin and marking checked (Auto Reboot , F. Reset Time , Phone EFS clear, Phone Bootloader update).
I suspect that the Phone EFS clear did the trick. It's function is related to the modem and radio of the phone. And clearly the modem has a problem here.
I hope this will help anybody out there having this issue.
This problem happened after trying to flash lollipop using FlashFire app to reserve the root that I had in my previos Android KK 4.4.2.

N910C update to 5.1.1 failed

Good morning, my friends!
I have a little problem while I tried to update my note 4 910c turkey version via Odin.
I flashed the original 5.1.1 rom. Everything looked ok, but when the phone rebooted nothing happened. That's not at my first smartphone with android so I really have a pretty ideea how to flash something via Odin.
Also I tried a few weeks ago to flash another original ROM and the same thing happened.
Can you give me some ideas about that?
Thanks a lot for your attention!
Cheers!

Did you follow the instruction givin in the sammobile website?
Did you unzip the file?
check AP then add on it
if so maybe you should re download the rom.
i did the update over the 5.0.1 no issues .... then i decided to wipe and flash clean and that was super good
what do you mean by nothing happened? it still 5.0.1 firmware ??
