[Q] Problems with the Full MR2 leak - 4G radio instability

Very odd problem with this new full MR2, probably radio related. When i upgraded it obviously did the full wipe so I know it's not a software interfering. It's pretty much a fresh reset since 1pm.
Anyways i keep losing connectivity to 4g. it flickers to 4g, then 3g, then 1x. Then back to 4g for a second, then it just loses connectivity to the internet totally but shows full bars. Now i'm back at 1x.
I am sitting smack in the middle of NYC where there is always full 4g & 3g bars. Anyone else experiencing this problem? I've done numerous reboots, put my phone in/out of airplane mode, etc but i can't hold a 4g signal for the life of me. Didn't have this problem in the AM before i upgraded. It's now flickering between no internet connectivity and 1x as i type this. I wonder if this is network related or the new firmware?

I was having that issue before the updates (the first one) when I was in NYC. I honestly think it may be the 4g network. the way I solved it was putting my phone on CDMA(auto) and it just held 3g.

I was having that same issue running The Perfect Storm. I downgraded the radio and went back to BAMF Remix and have had NO 4G issues. Good connection, great speed, and it never loses the 4G connection.

4g has been fine for me running the MR2 radio with flyweight ROM. I'm in Florida though, not NY...

I am in NYC and had the same problem....
I even flashed the first Ginger radio and still had the same problem...
10 min ago I reloaded the MR2 radio and I am getting 4g now....
I am 99.999999% sure it was the VZ network!
EDIT::: just went back to 1x.....I am sure it is the VZ network...just have to wait ait out

Interesting...I thought I would try this update again this morning with a different ROM (Das BAMF 2.0 - 5) and have had no issues at all. 4G is constantly connected with no drops. I'm not sure if something happened with the initial install or if it was an issue with the ROM I was using it with. Anyway, all is good.

Try powering down..pull battery and LTE sim. Reinstall them and power up.

sorry to necro, but this is the first relevant thread i found in search
i am in a similar situation, before rooting (stock thunderbolt), i could exaggerate and say i didn't even know what the 3G icon looked like, constant 4GLTE uptime in washington, DC
i'm using INJ3CT3DTH3ORY (pardon me if i have stylized the name incorrectly) with an OVA MR2, and now i'm constantly 3G. i've tried every setting under "set preferred network." if i do LTE only, it'll show 4GLTE for maybe half a minute, and then fall into 1X. if i do CDMA + LTE/EvDo auto, it'll show 4GLTE for a similarly short amount of time, then fall into 3G. all the other settings deal with 3G only if i remember correctly, so i'm not even bothering to mention those.
thinking it might have been the radio, i tried flashing MR2.5 and MR.627, both giving me the same result.
any ideas?
edit: found this thread, seems to be related as well (showing some effort here) http://forum.xda-developers.com/showthread.php?t=1178285

I am not experiencing these problems with BAMF 1.86

H+ vs H - speed test - quick revert back to check?

Edit: I'm gonna go talk about this in the Android Revolution thread, so I guess we can stop here. The phone is constantly switching to 3G mode now too, like every time I turn off the screen and turn it on it's in 3G mode, it has never done that, so something is wrong!
Not sure what else to call the thread, lol. Still working on my 10 posts after 1 year (ha) so I can't put this anywhere else.
As of yesterday I had S-Off, CID 11111111, stock Bell Canada ROM. It's been a while since I used the Speedtest.net app, but I'm pretty sure my results would be up to 10 mbps area, sounds about right for a 4G 14.4 mbps phone? I know when I last tested I was not upset at the result.
Last night I installed Android Revolution 6.2.1 XE with 3.6 Sense and Beats Audio.
http://forum.xda-developers.com/showpost.php?p=14192842&postcount=4
I have the firmware loaded, and everything went fine, and I can confirm that the recommended radio 11.68.3504.00U_11.21.3504.13_2 is showing in device info.
I searched the thread and found in FAQ that it will not show H+, rather H, and it should still be in 4G mode. But I just did a speedtest.net and can only get about 0.8-2.5 mbps no matter which server I select. I am in Calgary. I also searched and confirmed that I am NOT to select the T-Mobile 4G option from the ROM install menu, which I did not.
Is there any ROM I can quickly revert to that does use the H+ or stock like settings that I can do a speed test and see what normal results are? Or is anyone in Calgary on stock phone can run a rest? ha, not sure where else to go with it, and don't want to undo root and put stock back on.
... but something worries me that I am getting hosed on my download speed. Soemthing makes me think I am not getting 4G.
Any thoughts are appreciated!

Additionally, my ping on Speedtest app to the Calgary server, from within Calgary, is ~350ms.
Seems way high, perhaps that's the issue and I need to figure that out first?

not only a problem in your country..
same here in the netherlands (den helder)

Well I just had a friend test his Bell iPhone, I understand they are not 4G or may be on different frequencies or whatever, but same Speedtest.net Calgary server he got 5 mbps down speed and 56 ping, so I'm thinking my 350+ ping is the root of my issue, everything is sluggish. One more post and I can talk about this in the other thread I guess.

HTC ONE APN problems after Root

Hi Guys,
Just switched over from the Iphone and liking the Android platform so far. So in my tinkering quest, I think something got screwed up with my APN.
I flashed ViperOne 3.1 to my HTC One (T-Mobile phone, but I am using an AT&T SIM) with 4.3. Radio. 4A.21.3263.03 with the latest firmware from Tmobile (side note, Im still not sure if/how the firmware changes when flashing a new/custom ROM).
Anyway, I flashed Viperone and everything went fine and updated the new APN for ATT. With the stock phone, I had been using the "pta" APN and got great reception and LTE speeds. With the Viperone initial flash, same reception, same speeds.
Next, I realized I didn't install the Superuser stuff so I thought I had to reflash everything...which I did. On the 2nd go around, now I can't get the pta APN to work. I get cell service (same reception as before with full bars, but no data). The only way to get data and cell is use the phone APN but cell is 3G (>1mb) and 1 bar at best.
The only thing I remember doing that could have possibly screwed something up inbetween the two flashes of Viperone, is that I installed AdAway. Not sure it this would effect anything or not.
I've also tried totally wiping the phone and installing Viperone for a third time via a sideload. I have not tried going back to a completely, locked stock phone yet. Also, tried loading AndroidRevoltion but same deal. But given I am a noob, I am still a bit worried about screwing something else up flashing back to a stock locked TMobile phone.
Any ideas on how to fix the APN issues? I have tried all settings in this thread: http://forum.xda-developers.com/showthread.php?t=2172110
As well as a couple others and combos, but nada.

Anybody? Nobody?
Some more info, I took my phone down the street and messed around a bit at a local coffee shop. I was amazed when I didn't change anything and I got a whopping 46mb downspeed. Haven't really seen that in my area. Still only had 2 signal bars when everywhere else is usual 5. I am in San Diego so coverage is never an issue. Anyway, I then traveled about 10 blocks away to run an errand and it dropped back down to under 1mb. Same 1-2 bars. Something is definitely funky. The phone and data works. talking on it seems fine, just doing any network data stuff is very slow other than that one instance.

[Q] Horrible reception-- new phone development

I've started having some horrible issues with my phone connecting to Verizon networks properly. I used to be able to connect to 4G networks at my house and surrounding area with no issue, but now I've been having the worst time getting it to lock. Currently I'm connected to 3G at -99dBm in my household.
I originally was running stock, but fully rooted, S-Off. I've since switched to trying AOKP and now I've settled on Sinless GPe 3.4.7. I have not seen any real difference between them as far as getting a good connection to the network. I started switching ROMs well after I've noticed an issue, and I have not done much of anything to my phone in the last few weeks that I could attribute to the change. I've never dropped the phone or damaged it in any way.
I just recently traveled across the state and would run speedtests next to my wife's iPhone 5c and 19/20 times she'd show full bars with LTE service while I was either on 3G or no service at all. My phone will connect to 4G sometimes though, it's just not that often.
I read that there may be an issue with my SIM card, so I stopped in and had it replaced. The guy seemed very confused about the state of my phone software, so he blamed any issue I was having on the software installed. Regardless I did get a new SIM card installed. It did not seem to help at all. Can anybody help me? I'd hope to not have to go through the hassle of attempting to get the phone replaced!
Bootloader information:
HBoot-3.16.0.0000
Radio-0.89.20.0321
After rebooting my phone, my phone locked to an LTE signal at -112dBm. It does not speed test at over 3Mbps. Testing my wife's iPhone shows her at -100dBm and she was able to pull 30Mbps down.

There is talk of poor signal reception/speed in gpe threads. Cm based Roms, dunno. Try flashing a sense ROM, do some tests and report back
I recommend clean ROM or any other ROM on Verizon base

I just received my M8 yesterday and am having the same issues (both wifi and LTE) running the latest PA. Going to try something with a VZW base and report back.

I reloaded my backup of the Stock ROM and I am still seeing the same issues. It seems to connect sometimes but most of the time it will not. It seems like its just not getting a good lock. I am having trouble even using the phone at my house now whereas I've always had great service here. Doing a speed test now, the phone states 3G service, tested with 705 ping, download of 0.17, upload shot up to 58.19 (which obviously isn't true) and then froze while testing and has been here for over three minutes.

I would run the RUU and try again, and just see if something got boogered

Confirming as well that the reception isn't the greatest with this phone/radio in the so so service areas.
I live out in the country. Never had good reception with Sprint no matter the phone. Switched to Verizon with an LG G2 and service was fantastic at home for the 7 months I owned it. I moved to the M8 and now phone service is spotty at my house. It's the radio for sure. Wifes verizon moto works great at home as well.

I've had the same issue, updated radios, flash back to stock, and everything else. The radio on this phone IMO is terrible, even when it does get 4G I get like 8 mbps down with 4 bars of 4g. Once in a great while i'll get 18 - 20 down with 5 bars of 4g.

I've been experiencing the same things recently as well. It also affects sending SMS messages. I am on stock too (with s-off). Nothing changed on my phone though, it just started dying.

Never had signal issues. I live out in the boonies too. Signal is strong and switching between 3g and 4g has been smooth. I've been able to download torrents as fast as 5mb/s. Speed test results have been just awesome. As far as signal goes, it's been better than my note 3, DNA, and my wife's droid mini. And this is my second m8. My son has the first and it is the same as mine.
I would look into exchanging them if they don't keep up with other phones. The radio in this phone is actually pretty damn sweet, so if u got a funky one, I'd exchange it. Def try the ruu first, then exchange if that doesn't help.

[Q] anybody else having 4g connection issues?

About 3 weeks ago after installing the update of liquidsmooth 4.4.4 i randomly started dropping to 3g service in places that i normally had full 4g available. It has slowly gotten worse to where if im not on wifi, than the phone is pretty much useless. i normally have full coverage everywhere. so i originally thought that maybe something had gotten messed up on the update, so i did a clean install of liquidsmooth 4.4, and blackbird kernal and same thing still occurred. also tried carbon rom and slimrom, and no luck. so for the fun of it, i went ahead and reflashed the phone back to stock from backups and rerooted it, updated the modems and reinstalled liquidsmooth w/ blackbird kernal, and same thing. i have went through all the mobile networks settings and tried everything and nothing seems to help, idk if that update screwed something up or if its an issue that others have been experiencing as well, or if im just screwed and my phone phone is dying.... any help is appreciated thanks

I'm currently running OmniToad, and ran CM 11M8 for a short while. On T-Mobile at least, with the custom ROMs it's normal to see H+ only when data is being transferred; it will drop back to 3G otherwise. When I ran the stock ROM on the Relay, it would always say "4G" regardless of whether it was in UMTS (3G) or HSPA+ mode. Apps like SignalCheck or CellMapper will tell you which mode it is really in.
On the other hand, if data transmission is only going through as 3G, it could be a phone issue or a tower issue. Is LTE available in your area, or are they just getting it set up? I know when T-Mobile was upgrading the Chicago area to provide LTE, there were a few glitches here and there.
It was stupid for T-Mobile to brand HSPA+ as "4G" but that's a different rant.

yea LTE has been in this area for quite a while now, i had it with my S4 and it worked perfectly, i never had a problem with the service on the relay either up untill a few weeks ago the internet speed and and data coverage was great, not quite as fast as the LTE on my S4 but it was still more than adequate, i used to use the hotspot and stream netflix on my laptop. now i can usually get a text to send but calls usually fail and if i try and use the internet its impossible. it almost seems like its doing the exact opposite of what it should be doing, as soon as i try and use anything (not while connected to wifi) than it drops coverage to 3g/edge/ or to nothing at all. Im leaning towards the hardware failing side, but i figured i might as well give it a shot and post it and see if maybe i wasnt alone. thank you for your reply.
small note of background on me: first time posting ever in this forum but have been using the tools and roms from it for a long time, so im not a complete noob, but i definitely still have a lot to learn.
