So about a week ago I bought one of these phones but ever since I took the phone the phone (X727) out of the box I've had a really annoying problem where my data (4g LTE) just drops randomly like every ten seconds NO MATTER WHERE I AM and it's extremely annoying. When I'm streaming to music it buffers, calls drop, can't access the internet when I need to, etc. I currently have MetroPCS here in Florida. However when I unlocked the bootloader and flashed the RR custom ROM the problem went away. However I decided to go back to stock by flashing Turbo's EUI 21s v20 custom rom for US. I've also already flashed the modem zip. However I'm having problems again and don't feel like flashing another custom ROM. My device is currently not rooted nor have I flashed any custom kernels. Any ideas?
Had similar issue with brand new stock device thought it was a local issue and changed sim before root and flash. Wouldn't mind knowing what that was about

Use the modem for your network as has been said before .
Hey guys, hopefully you can help me get my S5 back on track.
KLTEUSC G900R4
The story goes:
I've been running CM13. Flashed a nightly, I notice my phone hasn't locked 4G basically all day. 3G only.
So I Odin back to stock using the latest firmware. Phone is still stuck in 3G. Phone does an OTA update to CPF2 baseband version. Still no 4G.
Took the phone to USC store, they provided me with a new SIM. Nothing changed.
I took a trip out of my home area, about 100 miles away I got 4G, but i had no network connection? The phone displayed 4G but i could not connect to any internet. It then dropped down to 3G shortly after and I was able to access data again.
Since then I've flashed back to CM13 (snapshot august 20th release) since if I'm going to be stuck in 3G forever, it might as well be on a ROM that I like.
Please help!
Thanks,
Jeremy.
Bump. Still no LTE.
If I reboot the device, the phone locks LTE for a few seconds, with network connectivity, but then quickly loses it and drops back to 3G. If I leave the phone in LTE preferred, it will run in 3G for most of the time, but occasionally totally lose data (I'm assuming its trying to connect to LTE) then go back to 3G.
Any Ideas?
flash the stock tar.md5 in Odin, reflash TWRP, boot it up fully, boot into recovery, make a NAND, reflash your ROM. Sounds like something got screwed up in the radio firmware
Will that still work even though I can't get 4G when i'm on the stock rom?
$50 reward to whoever can successfully restore 4G LTE to my phone. I've been living on 3G for 6 months and its starting to get to me.
I've been on Lineage OS with the same results. There was a firmware update, so I flashed it through Odin, and ran the stock rom/firmware for about 3 days with the same results. No 4G. Called up the US Cell Tech guys and they were going to check everything over on their end.
The last go round, I repartitioned the phone, did NandEraseAll, and EFS clear.
Any ideas?
Hi, I'm having a very perplexing issue. For the last few months I have been running cm13 on my phone but recently it decided to not revive/send texts or calls but still got 4g and signal. I hadn't updated the rom or anything so that wasn't the fault. Looking at the sim card info in the setting it says it's in service and everything, but says the "cellular network state: Disconnected". I've reflashed to a touchwiz rom and everything worked fine. So far I've tried different cm roms clean and dirty flashing, flashing just the modem on to the cm roms, restoring from old backup before all this, replacing the sim card. For awhile I though it was the APN settings weren't right, but the cm apn settings matched the TouchWiz ones. I've also tried different unbootlocking methods, didn't help. Worked with an unlocked bootloader running touchwiz. My brother has been running the same phone and rom I was and hasn't had any issues. I'm out of ideas on what's causing this right now, hoping some can help.
Had something similar happen. Try changing the APNS till you get a single
Changing preferred networks might help too
I am having issues getting other rom's to work. I have flashed lineage to my sprint samsung galaxy s5. I have the twrp bootloader installed and thanks to skillsoft tool i was able to get it to actially stick. I did not like lineage primarily because it has issues with lte and my 64gig sd card ( my 16gig worked though despite being significantly slower) So i tried moar rom by downloading it doing a wipe and installing zip. I let it sit for 40 minutes but it stayed on the samsung screen. So i thought ok maybe its the rom, i downloaded aj's a8 2016 port v2 did a wipe and installed it as a zip, same thing. Is there an issue going from droid 7 to these other rom's?
OK, So i was wondering if this is just me. I dont see much mention about this problem browsing the threads. Course i could be missing it. So despite not really wanting to i brought my phone back to factory. The LTE connection came right back which was relieving i thought maybe i screwed something up royally. So i re-installed twrp and flashed ResurrectionRemix-M-v5.7.4-20161121-kltespr figuring maybe its something with the neugat based roms. I still cant get my phone to connect with lte. I switch it to lte prefered, nothing. Switch it to 3g and i can connect. Back to lte still nothing. I am clueless as to what might be going wrong other than maybe its the modem driver?
The factory rom i used was G900PVPU3BOK4_G900PSPT3BOK4_G900PVPU3BOK4_HOME.tar.md5
Any insight on this would be very welcomed.
Well I am a bit confused on this. I took the stock rom and extracted the NON-HLOS and modem bin files. ( thank you 7zip allowing fools like me with windows to do things linux is often used for ) from the stock marshmello rom which i downloaded and previously flashed to my phone and verified it connects with lte. I made a tar with both of them and flashed that via cp on odin and i still can only connect with 3g. I am really not sure whats going on with this.
Ok Turns out not knowing what i was doing basically created a LOT of extra work for me. I use a 3rd party mvno called tello which is great for low cost low usage customers like me. I finally stumbled upon this thread: https://forum.xda-developers.com/general/help/tello-apn-settings-t3409432
Added the tello apn and whala worked like magic, didnt even have to reboot. I had to do this with it set to global. For whatever reason when its set to lte i couldnt add and save a apn. Once i added the apn then switched to lte whala lte connection.
Hello,
I have an international version Nexus 6p. While I was in Panama I accidentally removed the OS using TWRP, after rooting. I reinstalled the latest OS, TWRP, root, and used a custom ROM. I was dumb and didn't back anything up.
I couldn't make phone calls or access the internet with my phone on the network I used there, but I could with WiFi so I chalked it up to the ROM. Removed that and did a fastboot factory reset. I still couldn't make phone calls or receive them so I figured it was the network in Panama.
When I got home I still can't make or receive phone calls. I can text, and access the net but the service is very unstable. I am using cricket wireless, and I know it's not the service because the Sim was in my gf's iPhone and worked perfectly, and my friend has cricket and his is stable and works perfectly. I am running the latest Android 7.1.2 and would love some help with this issue.
I have tried flashing a new factory image, erasing modemst1 and 2 through fastboot, changing bands, using a different Sim card, factory resetting in general.
I have not tried another ROM (read somewhere that chroma would fix the issue, but don't really wanna jump back to 6.0.1 unless I have to).
Thanks for any help.
