Hello, I am currently running CyanogenMod11 build 2/16 with SafeStrap on my rooted Fire Phone with GApps with a T-Mobile SIM card installed. The problem is that when I set my preferred network type to LTE, within seconds, my phone goes into a bootloop and will not stop unless I eject the SIM card and set the network type back to 3G. I have tried choosing the correct APN and set the Network Operator to both Automatic and T-Mobile. I have also tried to wipe the Dalvik Cache but to no avail. I have also reinstalled CyanogenMod11 over and over again and verified the MD5. Any suggestions? Are there any root apps that may fix this problem? This did not happen when I used the stock FireOS, 4G LTE was running perfectly.
This is a known issue with the T-Mobile personal cellspot.

I now went back to a stock version of android 4.3 with root but this actual Rom I really like and the phone is showing up as T-Mobile and calling out/receiving calls and text work fine but still no data at all... heres what the download of the Rom now shows up as d2att_I747UCUEMJ2_root4.3_noknox.tar.MD5
anyone?? I think if I could get in to edit my apn I would be fine but the phones saying insert Sim card to access mobile networks when I goto more networks but like I said the phones working fine jus no data
I think I fixed my data issue by flashing a new modem thatnks to this thread http://forum.xda-developers.com/showthread.php?t=1831898
Im using a D855 LG G3 running the bumped v20F stock firmware (see the android dev thread) with no issues except this one...
Im currently in singapore using a SIM card that supports 4G on a network that has good 4G coverage (M1) but i simply cannot get LTE/4G to work at all.
Ive tried the WCDMA/LTE/GSM/Auto in mobile settings and it always without fail sticks on "H". Via the hidden menu i select "LTE Only" and i get no data connection icon (or data) at all.
Searching the mobile networks ive tried manually selecting the M1 advertising as LTE on the list but the same thing - it defaults to "H" and wont shift off there.
The APN im using is the one advertised by M1 for 3G and 4G coverage.
I dont think this is a ROM problem hence posting it here but ive got no idea how to solve it. Anyone got any ideas what else i can do/change or check ?
Other than rooted, the stock ROM is not modified or customised in any way - it was a factory reset, clean install.
Similar issue in Argentina, with 20b on my D855. Tried using the 3845#855# code, selecting even the LTE only thing, but nothing, no LTE. SIM card and service is working right (tested on a Nexus 5).
Any thoughts would be appreciated.

Try reinstalling LTEConfigs.apk under system/app
Unfortunately, I can't root or flash anything on this phone until I know it can use our LTE bands, or should I return it. Any other way?
Hi, I have a problem with my device. Disclaimer: I'm very noob so please be patient.
I'm starting to get SIM CARD REMOVED error since i changed my network provider. My previous sim card was not LTE, just 3g and it had no problem with the device. The new sim card is LTE. It took me literally 5 days after enjoying the new network provider till my device acting weirdly.
Before changing, I upgraded to MM. Originally my device does not support LTE, but then I played with the system (sorry for bad terminologies) and make the feature available. No problem detected with old sim card.
So, I tried the old fashioned way; Hard Reset. I had the device reset twice but nothing changes. Frustrated of the constant automatic reboot, I wiped all system, delvik, cache, etc using TWRP. Then i installed CM13 and use it as my OS. It works well. I got the signal with LTE data. Realizing that the ROM does not come along with Google Play Store, i installed gapps. Soon after restarting the phone, the signal only lasts for an hour then it says " NO DATA SIM". I figured a temporary solution which is, rebooting the device after you lost the signal. It is just temporary though. The signal will once again lost.
What I have tried: 1) Locking the simcard while the phone still got its signal.
2) Changing values using this guide-> http://forum.xda-developers.com/lg-g3/help/annoying-lg-g3-problem-lte-signal-solved-t3293721
* My sim reader does not seem to be having any defect.
Any help would be greatly appreciated! Thanks!
I have got this annoying issue with my sim card. Currently running cm9 eol and i don't get 3g data internet on this device. I have tried on other phones and 3g works flawless. I have also tried other sim card on galaxy w but im still stuck at 2g. I have tried to check on gingerbread different custom roms and it still doesnt work. I have also updated the baseband to xxlmb. Also tried changing apn. Sim network is Aircel(India)
I unlocked bootloader and installed purenexus on my friends N5X.
It all went good for 2 week then the phone was not connecting to 3G,though 2G was okay.I thought it was a temporary network problem.
Then after a day I wiped Data then 3G was back,but then after an hour It showed 2G again and then lost all network connection.
I saw that the IMEI and Baseband is okay so no problem there.
Things I did:
-wiped data cache.
-Flashed ROM again.
-Flashed latest vendor and latest ROM.
-Tried different SIM.
Still no network.
Any help would be appreciated.
Check current APN setting and edit to appropriate input. I personally delete other APNs my phone does not need. I'm throwing a random guess, but maybe it could be from the phone automatically setting APNs upon phone restarts.
