G4 data stuck between G & E and no higher. Stumped. - G4 Q&A, Help & Troubleshooting

Hello all. I have an unlocked H815 on 6.0 that's with Virgin in the UK.
For the last 2-3 months the data speed has refused to go above E and is often G even in urban areas and sometimes there's none at all. I've seen H for around eight seconds in all that time.
I've done factory resets, Virgin have sent a new sim, messed around with network modes. Nothing changes.
What's doubly weird is that I get H without changing a thing when I'm abroad. Alternative sims pick up 4G just fine in the UK.
I've pretty much run out of ideas. The data is usable sometimes but as that's my main purpose for having the phone it's getting on my nerves.
Does anyone have any ideas?

[Q] 2G Signal only, enabling 3G drops signal totally.

Hi everyone,
I have a generic unlocked desire 2.2, unrooted, as standard as they come and connected to Orange.
When I run on GSM only mode in network settings my phone is fine...
BUT..
Enable WCDMA or WCDMA auto mode.... and it will connect to 3G for about 10/20 secs then drop the whole lot, "emergency calls only" is all I can get.
I live in town with full 3G,and have tried at my girlfriends 100 miles away too. This has been going on for about 3 weeks, and so far I have.......
Hard reset a couple of times....
Had a new SIM from Orange...
Tried a different SIM (O2) in my phone - which works perfectly, sat browsing on H for about half an hour or more with no problem.
Tried my SIM in a different phone (Touch Pro) - works perfectly as well! 3G and browsing internet all fine.
So - Orange say its the handset.... and I'm not sure their 2nd level tech really exist, cos I've never got to speak to them or had the promised callback!
and HTC reckon its a network issue.
I can see both sides, but that doesnt help when your stuck in the middle with sloooooow internet.
The only other thing I can think is that Orange dont like the fact I'm on unlimited data and using it, I hit about 900mb a month normally and 2Gb in Nov when my home broadband died for about a week. perhaps they have blocked my handset from 3G? If so they havent told me though! I have one of the panther tariffs from mid last year which were "unlimited".
Any suggestions would be very appreciated!
Thanks in advance
Chris
Sounds strange indeed......
Theoreticly speaking, they could have placed some sort of a limit on your account to reduce the load on their network, but It'll be hard to prove. (Maybe you know someone who works there???)
You can look for your plan's contract (or ask them to fax it to you) - maybe it states the minimal speed of connection....
Threaten to disconnect if your speed does not improve..... Realy can't think of anything else.
EDIT:
Try this http://forum.xda-developers.com/showpost.php?p=10865272&postcount=5
Thanks,
I have tried all the options in that menu with no success.
Eventually last night I got orange 2nd level tech who was equally confused and could only suggest a radio version conflict with my handset and network.
Anyway they gave me a fault code which CPW (I purchased from mobiles.co.uk) looked at and glazed over.
I have called HTC direct now and they are having it in for warranty repair. 10 days with my old touch pro... how bad can i be?
Wouldnt surprise me if they send it back NFF........
fingers crossed!
EDIT: THE TOUCH PRO IS AWFUL!

[Q] HTC One M8 dropping data connectivity but showing 4G LTE...

Hey everyone!
I have a stock M8 with T-Mobile and I live in LA. I'm new to T-Mobile so I wanted to ask if this is normal.
My phone will lose data connectivity but the 4G LTE sign will stay on. Spotify will stop playing, Speedtest won't work, but the phone keeps telling me I have 4G LTE.
This happens a lot especially when driving, but today it happened while I was in the drive-through of a fast food place. I had barely moved and yet data was working fine at first, then suddenly "poof" nothing works anymore cause no internet, but the phone insists I have 4G LTE.
Usually turning data off and then on fixes it but not always.
Could it be an issue of switching towers? But then wouldn't my signal drop completely? Why does only data stop?
Anyone else having this issue or do I have a lemon phone I should return?
if you are jumping from tower to tower it may not relay properly. Call tmo and tell them to do a signal refresh. call from a different phone.
Do you have power saving mode on? The reason I ask this is bc it will turn your data connection off when your screen locks.

I feel your edge
Same here ,
Ever since I bought the m8 it happens to me time to time.
Ive tried dis n reconnect the mobile data or go on airplain mode, but sometimes reboot is quicker.
Hope HTC publish a bug fixed firmware soon
Its a provisioning issue on the towers people you need to call tmo...
This was happening all the time to me on my Note 3 which Is why I upgraded to the M8. Just got it last night and it's happened once. Also, the signal isn't as strong. My Note would hold a lte connection with barely 1 bar. The m8 not so much. Likes to switch between 2g, 4g and lte.

Did it work? I also just got T-Mobile and live in LA and it happens to me as well. I have a Nexus 5 though.

It was fine for a couple of days. Today however I had to wait in the car for 1.5 hours for something and was playing Spotify.
Didn't move for that entire period. For an hour it worked fine, then suddenly it did this again where it wasn't receiving data and yet the 4G LTE sign was on screen.
So I guess it didn't really help. I turned data off and on and it restored it, but still... that's not cool.

Yeah same here. It happens in my house when I'm using my phone in bed and just loses data but it still says LTE and have to either turn off and on data or reset my phone.
Also on my way to work today I was using Spotify the entire drive, which is about 45 minutes, and never lost data but on the way back it lost it about twice. It sucks and hopefully there's a fix of some sort.

I think is not phone problem
tmobile signal issue
my z1 and htc m8 sometime both have this kind of issue
they both show I still have lte icon but just can't connect to network
and sometime you must wait like 1-2 mins to reconnect to network
I have had my M8 for a week and have not experienced any issue with data loss. I am in Miami, Fl. If anything I get way better LTE speeds than I have had with any of my last phones( S4, G2, Iphone 5S)
Same issue with my M8.
Full bars LTE signal and sometimes data just stops working. Need to reboot the phone to get it working again. Was thinking about exchanging the phone but it seems like a software glitch...

I don't have this issue but I do have terrible speeds in south Atlanta.
3-5 bars in my home, and download speeds are from 3-6 Mbps down and uplad from 2-3Mbps up even with LTE. I get much better performance on HSPA+
LTE pings are half that of HSPA though
Just to add on here, in my experience this has more to do with the area and likely the towers supporting that area then software or hardware. Another possibility is T Mobile's network in LA is not 100% compatible with HTC is new radio firmware yet. If that's the case some tweaking by t-mobile on the backend would fix this issue straight away.
The reason I say this is because in Las Vegas, Nevada I never have any problem with LTE losing connection, however, this last week I was in Long Beach, CA (LA County) and constantly had loss of data connection while the phone would still displaying a full 5 bar 4G LTE connection.
Reboot or switching to airplane mode would fix it, however, it got to be so bad and happened so regularly, I eventually stopped using LTE entirely while there. The HSPA+ "4G" connection there was still producing around 10 megabits per second download which was more than enough. So, while there I switched off LTE and had no more issues with data connection dropping.
Long story short clearly seems to be an issue with T Mobile Lte Towers in the greater Los Angeles area. Possibly its an issue in other areas as well.

Happening here in South Houston too, but i am using a VZW M8 with Tmo.
I also have this issue, but I'm on AT&T and missing some bands that I need, so I was figuring it was that.
I had a galaxy s5 and had same issue.
So i know it's not the phone

Has anyone found a solution to this problem yet? My HTC One M8 has been losing data connectivity ever since I purchased it last month. It will say I have 4G LTE but I will loose data connection regardless. It's a nuisance. I never had that problem with the M7. My camera on the M7 got a purple haze so T-Mobile replaced it with a refurbished M7. It was the worst thing I could've done. The refurbished M7 would freeze and reboot a lot, until it finally got stuck in a boot loop and I lost all my photos, videos, and files. Would not go into recovery. Then T-Mobile sent me a plastic Samsung S4 as a replacement for that because they were out of the M7. The new M8 has been working pretty well except for the annoying data connection loss everyday. I have to activate then deactivate airplane mode to obtain data connection again. Only other time I ever had this happen was with a certain nighyly rom I put on my HTC HD2, but that was rooted, this is a stock phone, I never expected to have a data connection problem with a stock rom.
I had this problem for ages with straight talk with my old phone just before I bought my M8. Exactly the same issue in that my data would seemingly just cut out randomly after a bit then come back later(switching off/on and/or in and out of airplane would restore it).
In my case, it turned out to be my data settings. I played around with different settings one night and found that different settings finally got rid of the problem for me. Your mileage may vary, but it's an easy enough thing to try.

[Q] Cannot stay connected to any LTE bands. Need advice and ideas please.

Okay, here's the problem. Since June 3rd my phone will not stay connected to 4g. I toggle airplane mode and I instantly lock on to 4g. Signalcheck reads between -109 and -115. This is normal for me at home. Until the 3rd I could hold that lte 1900mhz (band 25) and never drop it unless i went further into my home. I almost never get band 41 unless Im closer to a tower. Band 26 is nonexistant in Buffalo (too close to canada).
Since then I toggle airplane mode and can lock on to LTE 25 (same signal strengths) but it drops to eHRPD 3g every single time.... Within 10-15 seconds. Same happens when I reboot.
I am running full stock, stock recovery, ZVG, and the G2 is rooted.
I have tried:
Disabling band 26 and 41. And connecting to any combination of them on/off.
Modifying the bsr timer, etc.
Updating prl, profile, and even reactivation many many times.
Factory reset on ZVG, 3x.
Full TOT back to ZVE, unrooted. (Still same problem even on ZVE, unrooted and yes I never had this issue on ZVE before updating to ZVG the first time.)
Redownloaded ZVG and reinstall after TOT, no improvement.
Called sprint and have been working with engineers in Oklahoma city office. They swear up an down its not a tower issue, or a eCSFB problem.
I have the same problem even away from my home towers.
I have opened the device to inspect for damage, or moisture, there is none I can see.
I havent dropped it hard, or exposed it to any water that I can think of.
So anyone have any ideas on what I should try next, or do to get my 4g to stick?
Im a bit at a loss. Ive tried every setting, trick, or troubleshooting step I can think of.
Thanks in advance for any help or knowledge you can provide.
For anyone that may have a problem like this in the future I solved my issues by having sprint send me a new sim card. Being that I bought my g2 the day it was released I guess maybe my sim went bad. It was a long shot and my last ditch effort to get 4g back. I now have a steady 4g signal.
Thanks for posting what fixed it for you. I've also been having this same problem for about the last 2 weeks. It just won't hold LTE. I'll stop by my local Sprint store today for a new sim and hopefully that does the trick for me as well.
Unfortunately even with the new sim card the problem returned after a few days. I called Sprint and asked them to put in a dummy sim number to unregister the sim, and then re-add the sim back. It fixed the problem immediately once again.
Frankly, I dont understand what the problem is. I know its related to the sim card but I havent reset (powered down) my phone in a week. Im kinda worried the problem will come back if I do. Cant see it being a bad sim reader in the phone. Otherwise it wouldnt start working on 4g again after resetting it via sprint.
Im stumped.
I can always call sprint and have them reset the sim again but Id rather know if its some kind of bug that will be fixed. I contacted LG and they acted like I am outta my mind.

3G?

Does anyone one else have an issue where the Verizon G4 get stuck on 1 bar at 3G? All of the rest of the phones in my house have full signal and 4G
Any idea how to resolve this? I have tried to reboot, I would really rather not update or factory reset but I am guessing those are the only options.
Is the phones running by the same carrier as your g4. If not there there u go
If it is i saw a poston here soneone is stuck on 1x for a bit. It take time for he phone to switch networks. Mine dose it at times
network switching doesn't appear to be the fastest on this phone. I'm sure there will be updated radios coming out which should address this.
They are also on Verizon. I also notice the wifi sucks on thethe G4 as well compared to the others.
Hopefully they will sort this out with an update.
Any ideas in the meantime?

Can't get good mobile speeds

I'm making this thread as I have a very hard time trying to find a solution on my own, I've read from these forums a lot in the past but this is the first time I make an account and post something.
First the problem: I have bought an used LG G3 phone that was bought with my carrier (personal, is from Argentina), once I got home I only used it with wifi and then flashed fulmics 5 and updated it (since I've read a lot about the phone before buying and found that the stock rom is very bad with battery, plus I really liked the rom as far as I've seen about it) and then flashed it again because I didn't select the options I wanted the first time, in both cases I've wiped data and did just about everything indicated in different tutorials, I've used twrp for flashing. After all that I've asked for mobile configurations to my carrier and at the next day, I asked my old man (the line is at his name, because of employee discounts and all that) to activate LTE for my line (I've never had a phone with LTE and with my carrier that needs to be activated in the line) and after following indications such as rebooting the phone, I decided to test my mobile speeds with LTE and they were incredibly slow (under 0.05 Mbps both up and down) and today I checked again with full signal and had the same results (give or take a couple of bps), I also installed a new kernel called xceed and tried again with no change in results (I don't know if the kernel would affect this, but I mention it just in case), and since I had my parents around at the moment, I made them try (same plan, same carrier, diferent phones) and both got normal LTE speeds (20+Mbps down, up varied), the weird thing is that my speeds are about the same with 3G H+ while wifi works normally, mobile signals are normal, even getting full bar during some of the tests, I have double checked more than a few tiems and I have the apn correctly set and all that. I don't think it could be the SIM since I've been using it with fast 3g speeds in my moto G before without a problem, but I'm still going to request a new SIM to my carrier just in case.
Short version: I've got unde 0.05 MMbps up and down in LTE and HDSPA.
Specs and all that:
- LG G3 D855 16GB version
- Carrier: Personal (Argentina)
- Data plan: unlimited speed, 500MB at a time, refreshing costs part of my credit and I've checked, I haven't surpassed my data cap, I'm far from it.
- Software: Fulmics ROM 5.3 and xceed kernel running 6.0 Marshmallow
- Emotional state: mixed feelings, it sucks to not be able to use mobile internet and the poor battery life but at the same time this is my first high end phone and it feels awesome.
I hope someone can point me in the right direction as I'm lost like an old-timer in the dance floor.
Extra info: I'll try flashing the rom again, but I would like to try different solutions first, there are some things I don't like to set up over and over, plus I want to know what could be the reasons, the very few people I've found on the internet with the same problem (excluding people talking about carriers from the US) had a case of a bad SIM card.
UPDATE: well, this is awkward... it turns out it was my plan, I checked once again and my data had to be resetted, now it works, 6mbps down and 1.3mbps up, it's not as fast as it should be but it works now. Sorry for the useless post
