So I got this phone from my Grandpa who recently passed. I was able to insert my AT&T SIM, reboot, and use the phone as normal on 4G+ without any issues what so ever.
Fast foward 24 hours and after rebooting my phone a couple of times and accidentally "Updating Profile" my 3G/4G no longer wants to connect. What's strange is Voice and Text still work as long as the text isn't a MMS since that server is also no longer connecting.
I have confirmed the radio is functioning as I can switch it off, verify it's receiving signal from the nearest WCDMA tower through the 4636 menu.
As well as airplane mode and wifi are working
Sometimes my wifi will not connect first-time unless I "forget this network" and use WPS button on Router to connect - it's like my phone won't authenticate the network once a password is entered. Once connected it stays connected without issue.
Some things I have tried already:
I have attempted to change APN settings to strictly AT&Ts 3G connection - no luck.
I've installed custom ROM, Recovery (Bad Boyz HTC 10 Oreo Stock ROM, TWRP) - no luck.
I've reinstalled stock firmware from HTC RUU - no luck.
Got a new SIM from AT&T and had a tech "diagnose" my phone - no luck.
I've searched all over the internet and found multiple threads about having no signal or no IMEI, but this doesn't completely fit my issue as you can see in my pictures I still have a valid IMEI and cell signal. AT&T said everything is fine on their end regarding my phone, but since it is not an AT&T phone any other support I'm going to have to find elsewhere (Screw AT&T)
The only other thing I can think to try is purchasing a Sunshine license to S-OFF and try manually deleting the radio partitions and then reflashing an older radio or stock radio, but I'd rather not spend $25 for this solution to not work or further complicate my matters.
My question is has anyone experienced this random loss of 4G connection but still have the ability to call and text on their HTC 10? I know this is an older phone, but I really like this phone after using my LG V20 for so long.
UPDATE: Put the SIM in my LG V20 that I was using prior to switching to this device and it is also now having the same issues.... Wtf is going on?
Thanks for any responses!

At your own risk, this:
In the bootloader enter these commands:
fastboot erase modemst1
fastboot erase modemst2
(this will wipe the faulty modem partitions we are about to reset)

Hi all,
I got my Desire from the British carrier "Three" last April when it came out. It was stocked with Android 2.1 but the phone was unbranded and not locked so making life much easier.
I rooted the phone weeks later and flashed a number of various roms and radios (usually newest ones recommended by rom developers) and just played around with them. No problems ever occured and everything went smooth.
However a while ago (about 4 weeks I would say) strange thing happened: when the carrier 3 does not gave 3G coverage it usually switches to other network's 2G roaming service. It is also possible to switch to 2G permanently by forcing it via phone settings. It stopped working in Central London for me while still worked elsewhere (very strange) so I had to rely only on 3G service. I thought it was a network issue at first but now I'm not sure.
Later (or at least so I noticed) the connectivity started fooling around: even when standstill (i.e. NOT in a train, bus etc.) and staying at home the network connectivity just disappears all of a sudden. Sometimes it comes back by itself and sometimes I just do it manually via netowking settings. This is much more common when on the move (i.e. on the train etc. even though it never used to happen before). Moreover, sometimes while manually searching for network it says "your sim would not allow to connect to this network" even though I try to connect to the correct one. Instead I switch "WCDMA only" and "WCDMA/GSM auto" options and connection comes back by itself. Then it disappears again after a while. Even more strangely, connection does not disappear if I am talking on the phone with someone but in other situations (such as browsing internet) it just disappears and I see no bars in network reception indicator and cannot connect to internet or make phone calls.
I know 3 has a reputation (deserved or not) of having "bad" network but I don't think this has anything to do with that. My Desire used to work fine before and never had such problems (except in specific spots which have bad coverage). Moreover, I have another old phone and it works fine without any problems with networking while the Desire messes around. I am sure it has either to do with firmware or, worse, hardware.
I have tried a number of roms, radios and settings and it's the same thing all over.
If nothing works is there a way I can still bring it to warranty service after flashing "unrooted" stock rom if there is one available? I'm so frustrated because I have no idea why this is happening.
Its because three have switched off 2g roaming I have the same problem. Search Google

Hi Guys,
So, I've been using the GNex for about a month. I moved to this phone from a Moto Atrix and here is what I have noticed and have looked around but didn't see any good answers to these questions I am having. Hopefully I get some answers here.
Device info:
GNex GSM version on ATT.
Running JB 4.1.1 Stock with Trinity Kernel (rooted and bootloader unlocked).
Issue #1: I get really bad reception at work. But, when I leave the building, my phone doesn't automaticaly connect back to the network. Sometimes, if I don't check my phone, it's been like that all night long until the next day when I have tried to make a call and it said "No Network Available" and I have to either reboot or toggle airplane mode to get back on the network. Am I missing something? In my past experience with other devices, they try to automatically connect back to the network when they loose connectivity. Also, if I get in an elevator during a call and the call gets dropped due to network unavailability, it doesn't connect back to the network and I have to toggle airplane mode. Has anyone else had this issue?
Issue#2: This is with the stock mail app. Specifically the search in this mail app. No matter what, it always returns zero results. Has anyone had this issue with the Mail App? If I use the Gmail app, it works fine. That's what I am using now, but am curious as to what I may be missing that make it not return any search results in the stock mail app.
Q3: Speed Dial: How do you set speed dial on the dialer? Is it even supported?
thanks in advance,
vG

it could be to do with your radio, what version is it? baseband version in about phone. im no expert but when i flashed a jellybean rom i had to update my radio afterwards cause my signal was dropping alot. i also had the same problem later on but that was down to my network operator. before i realised it was them i googled my problem and a few forums suggested that my sim card was goosed. so maybe check those three possibilities? i cant help with the other two issues unfortunately but good luck sorting it out!

I have a stock GN, rooted, but still running stock ROM. Anyways, a couple weeks ago, I started noticing issues with the cell connection. The cell signal triangle would lose all bars and turn into just a blue outline of the triangle (i.e. not gray in the middle). Mobile data wouldn't work, and toggling airplane mode wouldn't bring it back. Rebooting the phone seemed to fix the problem, but it just happens again every couple days.
Is there anything I can do to fix this?

Have you tried searching on here for another radio?
Find one compatible for your particular device, download and extract to where adb is.
Then boot into fastboot mode (with unlocked bootloader) and type fastboot flash radio (name of radio file).img
fastboot reboot
Should improve reception hopefully.

I don't think it's a reception issue, as I usually have 3 - 5 bars at home when this happens (not that it's limited to happening at home). I'd rather not install a different radio, as it's using the stock radio and I don't want to add more complexity to the issue.
I'll try and get a screenshot of the status screen next time this happens.
Radio is updated. Even with the latest build of android, you may not have the latest radio.
Upgrading the radio should definitely help if you're willing to take a chance.
I had similar issue with both stock and custom ROM. Upgrading my radio has helped and I never get a disconnection problem.
Hope that helps

Update bootloader to the latest version as well. Use "GetRil" app to check that your RIL and radio firmware version match.

Mobile Network State Disconnected
OK...I’ve been having this problem for a few months now. I can make calls, text, access voice mail...I just can’t connect to the internet without being connected to a WIFI network. I can’t send email or receive email or use an app that requires internet access.
I’ve tried...
*rebooting
*switching WIFI on and off (it is set to automatically connect to a WIFI)
*removing and reinserting the battery
*drained the battery completely and then charged it completely
*going into airplane mode and back out
*updating profile and PRL
It is data enabled and set to connect to data services when roaming.
I have no SD card.
CDMA is set to automatic (there’s only 2 choices: Home only and Automatic)
Preferred network mode is LTE/CDMA. (Again, 2 choices: LTE/CDMA and CDMA) I’m at home now...turned off WIFI on phone and changed network mode to CDMA. Opened Chrome and it opened the page. I went back to LTE/CDMA and it opened the same page. I’ll have to try that when I'm running errands or something and not logged on to a WIFI.
I finally took it to a Sprint store here on Friday, May 9th. Spent about 10-15 minutes with the person. It was fixed and working when I left the store.
Guess what? It’s disconnected. Again.
I’ve had this phone for a little over a year. So far, I’ve replaced the charging cable (twice, not including the ones I broke) and battery. I can’t change phones until next year without shelling out a few hundred bucks--which I don’t have.
Any help and/or suggestions (even sympathy at this point) would be helpful. I’m extremely frustrated!
Hello!
I have a big problem with my G4 (H815 version, Germany) beginning with the switch from CM13 to the (stock based) Genisys 3.2 ROM. I've tried to fix it for three days now but without success. It doesn't stick to LTE anymore like it should do and did before. After a reboot it does sometimes connect to LTE but after switching back from wifi or airplane mode it's showing the "no signal" icon. Then it takes some seconds until it reconnects to the mobile network but now just to 2G or 3G. From this point it's not willing to reconnect to LTE, even not through the manual RAT-selection. "Force LTE" using the hidden menu then results in no network connection. However, after restoring my EFS-partition-backup with TWRP (from a time when it was working perfectly) it's connecting to LTE directly after boot but only once and only until you toggle wifi or go offline - like described before. After the next reboot it will mostly connect to 3G and then maybe switch to LTE sometimes or not.
Of course I have checked, deleted and restored my APN multiple times, I have also recovered to a stock V20b and V10d .kdz using LG UP in refurbish mode. Unfortunately even on the fresh and untouched V10d install it shows the same strange behaviour. Restoring the CM13 backup (including EFS partition), which has worked perfectly before, shows the same network bug now.
My sim-card is still working perfectly in my other phones. It still connects and reconnects almost instantly to LTE in my old S4 in places where the G4 did the same but struggles now.
I have even tried the cdmatool which is used to unlock additional LTE bands. I didn't change anything but it does show all usual LTE-bands which are needed for my provider.
Does anyone have an idea what I could try next? I'm living in an area with much better LTE than 3G connection and paying for a quite expensive LTE contract so a working LTE is very important for me. If I don't get that to work again I would need to replace my just over one month old G4 :crying:
Many thanks in advance for your answers
f-rouz
Meanwhile I have also tried another simcard. Still no LTE
i have the exact same problem, well, almost. no unlocked bootloader, but when i first got the phone i root injected the system.img and flashed away, thought everything was fine. now it just doesn't reconnect to 4G. well, at home at least. on my S4 i get 4 out of 5 bars on 4G, with the G4 i get 2 or 3 bars out of 5 on 4G, so the signal isn't great but good enough. i live in hastings (a town) and went to brighton today (a city) where the signal is max 4G, and the device does pick it up. but as soon as i go through a 3G area to home, it doesn't reconnect. have tried flashing original system.img back, upgrading to MM 6.0 after factory reset (via LG bridge), then downgraded again to V10c via LGUP - factory reset before the downgrade, no joy, still the same.
when you say you have forced LTE in hidden menu, did you try this - enter 277634#*# in dialer and go to field test > modem settings > lte band selection and select the band for your operator, which can be found on 'wiki europe lte bands'. there were two bands for my provider (three UK) and band 3 was what i wanted. i can now switch to 4G but it's a pain having to this every time i come home ( i use my phone for home internet via tethering).
worst part is, having refrained from unlocking the bootloader to save the warranty, i phoned LG today to send it back as faulty and explained i could switch it to lte band 3 via the hidden menu and they told me my warranty was now invalid as had OPENED the hidden menu (they told me this after taking my imei). so if anyone reads this and phones LG for a repair, don't tell them you have accessed the hidden menu if you have done what i did.
think i'm just gonna sell the phone, make a palpable loss and buy another one, as i love the phone
Wow, I haven't thought that from LG. I feel like I've searched the whole internet already and nobody has a solution to this problem. I'm about to send my G4 back to Amazon (or sell it otherwise), hope the best and get myself a Oneplus Two because the G4 seems to be too *****y from the development standpoint. I've never had a situation like this with my previous Samsung phones since 2009. I will miss this camera though. And the NFC and the wireless and fast charging capability... the G4 is a nice phone nevertheless...
Edit: And yes, I have tried the "277634#*#" hidden menu, although it isn't accessible through this code on MM any more (you need a terminal command to start this).
Have you tried limiting it to 4G/2G in hidden menu? Mine also have a similar problem in Lollipop in that it is very aggressive in dropping to 3G. That worked for me. Phone doesn't drop to 2G much provided you have decent LTE coverage.
Now I'm on Marshmallow and not rooted, thus cannot do the same. Though it seems to be sticking to LTE a bit better than before.
I have tried that but it doesn't work. As I don't get any network connection wenn forcing LTE only, forcing LTE/2g results in 2g only.
My G4 still doesn't want to connect to LTE so I have ordered a S6 now... As I still have no idea what was causing this I just can't risk that happening again. It has been a short journey for my first LG and me and I really liked my G4 actually... Bye G4 community
you just needed to flash the stock modem, most likely
Unfortunately, it isn't that easy. That was of course the first thing I did (and not just one time)...
After a phone restart, VoLTE/4G Calling and Wifi Calling work for a short period, then stops working, usually after moving around between mobile towers and/or wifi hotspots.
I find it happens whenever the device loses mobile signal, or when the device flips down to 3g and then back to 4g, 4g data service returns but both VoLTE calling and WiFi Calling remain disconnected despite being enabled in settings.
This happens on my primary SIM only. I have a second sim in my phone at the same time which works perfectly with both VoLTE and wifi calling. I upgraded from a Mi 9 phone which worked perfectly with both these SIM cards.
Looking at the device logs (With Logcat reader), I get lines like
QImsService] ImsServiceSub : [0] Permanent IWLAN reg failure (IKEv2 auth failure)
I also see
IKEV2ErrorReceiver] Canadian configure is not set, return
Other things I've tried:
Updating to the latest MIUI version (12.1.5.0)
Network settings reset
Only using the one sim
Removing the second SIM
Clearing all caches
Clearing caches and storage of things like CneApp, Carrier Services, Phone Services, Phone, anything carrier related
Resetting APNs, adding APNs with bearer set
Setting phone to prefer 4G/LTE (ie do not connect to 5G)
Removing my VPN, same problem with VPN installed or not installed.
Removing sim cards and leaving phone off for a while (an hour or so)
Getting a replacement SIM
I have not tried a factory reset yet, as I am not confident in being able to back up the phone fully and other threads with similar issues suggests that won't solve the problem.
One way I've managed to get it stable is to dial *#*#4636#*#*, go to phone and set preferred network type to "NR/LTE". The phone does not connect to 3G or below in this mode, and unfortunately this setting gets reset when the phone restarts.
At this point I think its a problem with the MIUI software version itself, or some firmware driver that comes with these versions of MIUI. I'm hoping MIUI 12.5 will fix it, but I'm wondering if anyone else has seen this issue or knows what else I can try.
Upgraded to 12.5.1.0(RJDEUXM) and the issue is still present, also tried asking my operator to completely reprovision the line with no luck.
I guess I'm stuck with this behaviour until I upgrade my phone
STEP #1) See if VOLTE works normal when switching towers with a different phone.
If it does then you can try the things below, if it doesnt maybe it might be the cellular carrier issue.
If other phones work find then please note that VoLTE mainly works on 4G LTE ... donest work on 2G or 3G and may or may not work on 5G depending on your carrier. Find out what NETWORK BAND your phone is using when VOLTE is working. You can use a app like
Network Cell Info LiteOnce you find out the band you can then use a script or use a app so it stays on that network BAND. A little more advance but it may also possibly be a DNS issue in the tables during the change of towers during the reprovisioning... you can try a script to flush the DNS and reload the tables when the network info changes or bind them statically for testing purposes.
Still doesnt work it may just be the firmware's modem issue with that phone in the way it handles re-provisioning process during cellular multiplex switching.
