[Q] Mobile Signal crash! Please help! - Galaxy S 4 Q&A, Help & Troubleshooting

Hello there! I'm having problems with my S4 i337m (Rogers). I updated last month to the latest nightly of Cyanogenmod and I've been having problems with my mobile signal stopping every 20 minutes for around 5 minutes. Since then I've been using the Cyanogenmod M9 Snapshot release since that the only stable custom ROM I can run. Yesterday I decided to flash an S5 port ROM (Echoe) and I got the same result: mobile signal drops... What do I have to do to get this working because it seems that I can't run any other ROM other than Cyanogenmod M9 Snapshot. I really want to try all the ROMs out there but I just can't like this. What do I do? Do I have to update something? What's wrong? Thanks in advance!

[Q] Any lollipop roms for the SGH-i337m

I've been looking for custom roms with android 5.0 (lollipop) to flash on my Samsung Galaxy S4 SGH-i337m (jfltecan), however I can't find any. I know Cyanogen mod has cm12 for the jflte but not for jfltecan, can I still flash cm12 for jflte on my device or will it brick it? I used to have an s3 and I flashed carbon rom for d2att, edited some lines as to bypass status 7 and it worked fine. I was just wondering if I could do the same for my s4. Thanks!
Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck

So you are not having any issues at all? I am considering doing this. Do you have a link to a guide you used?
I use the AntaresOne Rom from this Link http://forum.xda-developers.com/showthread.php?t=2557353 with my sgs4 (sgh-1337m) from Fido and the only issues are wifi is kinda wonky(doesn't always save network info, doesn't always connect, sometimes drops connexion, but it DOES work fine when connected) and battery sometimes drains really fast. NB that this last issue has been labelled "cosmetic" by someone who knows a great deal more than me about Android. I have NEVER had my phone run out of battery and shutdown., just some days at 6pm it says 25%, other days it reads 76%. Kinda random. About to test the "Danvdh's GPE Edition ROM" 5.0.1 Lollipop, will post when I can confirm working or not.
EchoeROM is a good one.
No service after flashing...
I was on SlimKat 4.4.4 which was good, but wanted to upgrade to Lollipop after seeing it on my Nexus 5 (which is now broken). I have a Bell SGH-I337M
I first tried the CM12 Optimized build, wouldn't ever get past the boot screen...
Tried GPE, and it installed and ran fine, but my service was cutting in and out (so basically useless)
Tried SlimLP, it also installed fine but I was having the same service problem as with GPE.
How are you guys installing these ROMS? The only info I could find to fix the problem involved modem/radio.. I tried flashing a LP modem with the ROM but it didn't work. And all the radio-related information was from 2011 so I didn't bother with it. Any help would be much appreciated, I've been messing with this for 2 days now and get seem to fix it

CM13 - WiFi's stuck on 'Searching for Networks' dialogue

Hey guys, I've been using CM13 builds on my Nexus 6p for last few months. Generally, i flash new builds after 3/4 days from the last one. Everything's works fine, no big issues; but recently from last months build which ever update i flash on the device, the WiFi seems not working. It shows, it's on - Searching for Networks; but not able to connect or even find any network at all. And i tried to flash back to the older builds of CM13, the WiFi works fine on those builds quite fine. Beside this, I've tried Paranoid Android ROM on this device, WiFi works fine on that rom. So, have any of you faced such problem on CM13? And, please can anyone help me out on this matter?... Thanks in advance...

I've been successively flashing the nightlies from 07/24 until today and have had no issues with Wi-Fi. Sounds like yoh crossed over drom June to July build. Flash the July vendor image then re-flash latest cm and you should be good to go. If you use a custom kernel also make sure you are using the latest version made for this month.

Samsung s5 G900F not booting after MIUI 7 install

Hi everybody,
I am new to the forum and new also to modifying android phones. I have a G900F and I wanted to try a few custom ROMs. I first installed Lineage 14.1 and everything went pretty smooth. After I wanted to try the official S5 MIUI7 v6.5.27 which I downloaded from the MIUI website. I wiped everything I could and installed the zip file with TWRP. There was no progress bar but it seemed to perform tasks. When finished, I rebooted but the phone is stuck on the Samsung logo without any progress. I tried many times and I always had the same issue. Could you please help me out with this? What can I do to fix the install issue? My phone is now working (installed the Super Lite by Vincom) but I would like to give MIUI a try. Any suggestions?
Thanks in advance
Miui 7 is based on android lollipop so you gotta flash lollipop bootloader and modem in order to get it working.
I would like to suggest you MIUI 8 by blackbuga, you can find the thread on Galaxy s5 development (snapdragon).

Thanks! That was a quick reply!
I imagined that there was some issue of this kind. I was driven to v7 for its being an official release and stable. I saw that blackbuga's is beta and thought it was unstable. Well actually I wasn't relying on my skills, as I said I have been playing around with rom's for a week or so.
I'll give that a try
