I have this really weird problem with my Moto G4, for some reason it is stock in 4G, even if I go to settings and try to make it stay on 3g or 2g, I have also try with the code *#*#4636#*#* and nothing. I factory reset it a couple of times now and it doesn't change anything, the weird thing is that it was working properly before, making calls and everything, at this point I don't know if I should just return it to Amazon or try to mess around with the software to see if that makes any difference. BTW Im not in the US so returning it to Amazon should be my last option since it is quite complicated. Thanks for any help!
I've had a similar issue where I could not connect to LTE. I was stuck on 3G, and when I specified LTE-only, no signal. Reboots/etc didn't fix it, but I was able to fix it by booting the G4 into fastboot, connecting to my computer, and issuing the following commands:
fastboot erase modemst1
fastboot erase modemst2
Rebooted the device and it connected to LTE again.

Hello guys, spent so many time for that issue that I give up researching. Long story short:
Got bricked LG G2 F320K
Performed testpoint circuit and fixed QUSBULK. Android 5.0.2 had appeared but without call ability (Can't register on network or no sim, can't remember which one exactly)
Fixed GSM by "dd"ing F320LSK_EDGE-_V3 - modem modemst1 modemst2
And everything was ok after that.
After some time Wi-Fi connection dissappeared. When I pressed "Wi-Fi" icon in notification area - it plays enabling animation in a loop permanently (Reboot doesn't help)
I've reflashed stock rom and repeated steps above - got same wifi issue. (WiFi was ok for some time and then broke)
There were also "dd" of misc partition (Do not remember why)
So, the question is "Is it hardware issue or still software? What can I do to fix this or reach problem spot"
I have fully working d802,d801 near, maybe I should "dd" one of it's partitions? Or use QPST/NV manager to fix something

Hi everyone, I'm new to this forum.
I purchased a Moto X Play a couple of days back, everything was working fine till today morning when I was struggling with getting 3g network on 4G/3G preferred mode. I decided to change the preference in phone setting using*#*#3646#*#*.
Upon trying different options it remained stuck to gsm only mode, so I tried clicking "turn radio off" a few times which would make the signal go and come back in a few seconds but suddenly I lost network in sim 1 and have been trying everything for last couple of hours but won't get the signal back. I even tried swapping the sims and using a different sim but network in slot 1 is still off the radar. In the sim setting the phone would show the sim but there is no network. Any help in this regard will be highly appreciated.
Thanks

lastweek i faced same problem.
It is caused by selecting us band
you can just flash modem and it will recover.
modem file is in this forum. you can find it easily
Thanks for the reply. Can you please share the link to the file? Also please tell me if it will void the warranty as I've the option of replacing this piece.
http://forum.xda-developers.com/moto-x-play/help/modem-file-t3255312
get modem.bin file at this page, and flash it.
fastboot flash modem modem.bin
fastboot erase modemst1
fastboot erase modemst2
I'm not sure but you don't have to unlock your bootloader for this process, so your warranty will be ok. i think.
Do I need a pc for this process or it can be done on phone itself? Can u plz share some step by step tutorial as I am a novice. Also please tell me if there is some simple method to do this without using a pc.
Update: the ROM in above link is for single sim model while mine is a dual sim model.
So like a lot of people I took the Oreo update and at first I didn't have any internet connection. So I left it here and it looks like someone in the house attempted to go into my recovery and try to revert back but it didn't do anything and then we ended up erasing what was there because it would not boot back in to the shield. Then we tried using a ROM but anytime you install a ROM and it goes to the main part of the shield where it ask you to sign up with your Google account it force closes and Google Play and other Google things in the Play Store they can't open they don't work. So then we try to use fastboot mode but when you type in fastboot it shows that the device is there but if you try to flash any part or Flash anything it says the device is not emulated? What do I do some one tell me I'm lost.
You can try wiping the data with the "fastboot -w" command. Also, which model of Shield TV do you have?
Ok.....so after my other issues i have posted here in this thread...which still appears to be unanswered.....
https://forum.xda-developers.com/axon-7/help/modem-issue-t3917268
I have noticed that i do not have fastboot!!! i cannot get to it neither through Axon7Toolkit, not through ADB, and neither through the black warning screen if i hold Volume (-) and select "fastboot", the phone just boots on to the system. I have done EDL flashes through the djkuz's app and it doesn't seem to do anything really, as my computer recognizes just as before and with adb permissions not needed. I though the EDL flash formats data as well........
Do I have a partition missing???? If so, how can I restore it? what is a sure cut way to return as if to stock truly like purchased from ZTE themselves??
Any help guys would be much appreciated

Fastboot functionality is gone after stock B19.
If you want fastboot, you're going to have to EDL flash B19 Chinese firmware, that's the only one that has fastboot afaik. You're not missing a partition, the phone rebooting to system after selecting fastboot is normal.

Hey thanks for that for that answer. I was hoping that was the smoking gun.......So if you don't mind.....if you know....I pretty sure it was discussed here somewhere......what exactly is the "vendor" partition? That to me is a bit new as I do that recall that being a "common" partition as like modem, or recovery etc....there's got to be something missing that is not letting my phone get signal anymore...I can pop my SIM card in and it'll receive a message that I have "voicemail" if I have one that's still new, but it won't get service......I know for sure it has to be something software related.........

Are you 100% sure it's not a hardware problem? The phone not getting signal anymore can be due to many reasons.
Check the SIM card, make sure it's not defective. Try inserting it into another phone and check if it works. If it works in the other phone, then you've ruled out the SIM card.
Check the SIM card slot, make sure no pins are bent or broken. Check that the SIM card goes into the phone correctly, and if you've previously opened up the phone then check if there's any internal damage.
If you believe it's a software problem, try these:
Try resetting the APN (Settings>Network & Internet>Mobile Network>Access Point Names), or manually retype your APN (You can find this by googling for your carrier's apn eg; TMobile APN).
Check that your IMEI is still good, you can do this by inserting the SIM and heading to the Dialer, and typing *#06#
Check that your IMEI still shows up and make sure it doesn't show Null.
Go into your Dialer again and type
*#*#4636#*#*
It will bring up a menu, click on Run Ping Test and check if your phone shows Connected.
Need your help. I just accidently selected radioband USA settings on my htc one m8 in *#*#4636#*#* menu. Now the network on my phone is completely gone. I searched on the internet about this issue and found a solution which was to erase my modemst1 and modemst2 using adb and fastboot. I installed all the htc drivers and minimal adb and fastboot. First i rebooted my phone into fastboot and then gave the command "fastboot erase modemst1" But it says that "failed (remote:not allowed)" and the same thing happened for modemst2. What does this mean? And how it'll allow me? I have tried almost everything now. But it still wont allow me. My phone is rooted. S-off. And bootloader unlocked. Is there anyother way to get my network back? Your help will be really appriciated. Thanks.
It would probably make more sense to ask in the appropriate forum for your HTC device...
