Anyone having signal issues with Radio 3.42.30? - Mogul, XV6800 ROM Development

Anyone having signal issues with Radio 3.42.30? I have the verizon xv6800, and i am dropping calls and having signal issues left and right where i never had issues before with any Verizon phone?

I dropped only one call, and that's when I was at home over the 4th. I have terrible service at home (usually no bars even show, 1 at the most), so I can't really say much. You want want to try the whole M.IP settings fix that everyone has been doing, it might help.

See if doing that stuff helps any (i know it seems slightly irrelevant, but it can't hurt to try)

is it more irrelevant that 1 of the settings that supposedly needed to be changed was already correct by default? does that mean i shouldnt be having any issues and i just wished i had better service than i do? haha

How I did it:
Write down all the settings you currently have. WRITE THEM DOWN.
Change all M.IP settings to wrong values. Save, and if it dosen't tell you SR the phone.
Upon reboot, wait 15min and set the settings back to what they are supposed to be. SR if it doesn't tell you to.
Now, It took me like 10-15 of these cycles in order to get my phone to work... I don't know if it was my phone, the ROM, or VZW sucking. But now I get instant service, and plenty of bars.

I'm on Sprint and not having any issues at all - the only change I've noticed is faster GPS locking. I also have crappy service due to location, but when I'm not at that location, it's been working flawlessly. No dropped calls.

Since switching over to the new Radio I'm having dropped calls, VERY poor reception, and almost no bars in areas where I usually have great signal... frustrating, I'm going to downgrade as soon as I have the chance

I'm having the same probs (Sprint) I switched back to an older radio and it was fine again.

Dont you have to worry about certain ROMS and older radio's

I've also noticed that when I try to use the internet at home my internet sometimes refuses to work because the signal is too low when it always worked great before.
Also, this may be the source of my text messaging issues (have to resend about 4 times sometimes before it goes through).
I live in the country and have never got great signal but I didn't have as many issues before. I'd rather not downgrade... is there a newer radio ROM out somewhere I could try?
If I were to downgrade, any suggestions on which version to use?

Over the past few months starting just before 3.37 was released my signal went to unusable phone at my house. I was using 3.39 with the same results but was happy with the radio all in all. I bought a touch using 3.37 by default. It still had crap signal at my house but better then my titan I could atleast stay on the internet. I put 3.42.30 on my titan and my signal went from 0-1x to 1-2EVDO instantly. Now my phone acts like it used to the day I got the thing. I can kinda use my phone again lol instead of useless.

lost signal
i have had 5 dropped calls where i usually get great signal. and GPS still takes time to fix but does seem to be quick. I DEF lost signal strength when upgrading.

How many that upgraded are on Sprint vs. VZW..?
As I read the posting, I've noted that it seems that (unless I'm wrong...) those reporting improvement are currently Verizon Wireless users, and those with more dropped calls, etc. are Sprint users. Am I reading between the lines here, or is that accurate? If so, then those of us that are VZW customers should do the upgrade to the 3.42.30 Radio...! (and those of us on Sprint - should not.)

I'm on Telus in Canada and have worse signal as far as I can tell.

I'm on Sprint and everything works great, GPS is better!

If what you're saying is true, it's a coincidence.

Okay... let me be more direct...

Those of you who've upgraded to the new 3.42.30 Radio...
1. What carrier are you with?
2. Did you notice any improvement, and if so - what? Please describe.
Thanks from all of us.

I am on Verizon. Switched back to .02. .30 was not working well for me. .02 works much better, GPS and service wise.

Sandy,
I'm on Verizon and use 3.42.30. There are noticeable improvements in both GPS lock time and overall signal strength.
My coworker is on Sprint, uses 3.43.30 and also notices an improvement in signal strength (GPS lock time is moot for him as Sprint uses aGPS and his lock times are near instant).

XV6800 with 3.42.30 and it seems no better/worse than it was before. GPS does work now, it didn't previously when 3.42.02 was loaded (It did with 3.35 too).

VZW
im on Verizon, and 2 different units verified the poor signal and dropped calls. i used to get great signal with old drivers maybe could be something else...
3.2.0 DCD with 3.42.30

Spring Mogul Updated to WM6.1 - Connection Issues Now

I just upgraded my Sprint Mogul to WM6.1 from WM6. Prior to the update my phone worked great. Now, it roams all the time so I can't make (receive?) phone calls. I also connect at lower than EDVO a lot. What happened? What can I do to fix this?
Also, are there extra charges to use the phone service when it is roaming? How does that work and how much does it cost?
Thanks in advance guys!
I was having the same problem. I updated my PRL to the most recent and have had MUCH better signal.
I have the same problem too... I am not sure what is going on.. My phone keeps dropping down to 1X even though I have all 5 bars. Please help someone!!! I have tried pretty much every PRL since 60611 and also done a PRI update to 2.04... Can one of the experts please help here! I reflashed a dcd rom and have tried Radio 3.42.08 and 3.42.30.... But nothing seems to be helping.
Bump! Urgently need a reply to this...
I'll keep an eye on my network indicator, but I haven't had any major issues with making/receiving calls yet...
But I do know this latest Sprint rom seems to be ridiculously slow for me in the typing aspect...

I think I have a theory about this.. I have a feeling that somehow the phone ends up roaming onto Verizon's network but the phone does not know that its roaming so it does not try to switch to another tower. Since it gets a better signal it just keeps to the tower its connected to. I know there is a HomeID that is specified in the Phone's programming but its 0/0 for me on Sprint. Could that be an issue?
I also recently upgraded to wm6.1 i noticed once i upgraded my EVDO bars were going up and down like crazy. while in 1x it's all the bars. can't figure it out. seems to work better in 1x than in evdo.

[Q] 3G acting strange..

So all of a sudden my TB's 3G started acting odd. It disappears (the 3G icon disappears) unless I'm checking for updates, in which case it randomly reappears and seems to be doing work. Toggling airplane mode on and off doesn't help nor does turning the phone on and off. I can still get texts and calls but no 3G...
Tried everything (going back to ROMs that were backed up from a few days ago) as well as flashing that full new ROM/radio update. Wasn't doing anything specific before it went out...
Any ideas?

I didn't find that this worked at all. Only since the new radio was installed have I found 3g drop because I know I am in a partial 4g area. So for the time being I don't want to turn of the ePHRD. Has anyone else experienced this since upgrading radio and such?

Well I did upgrade the radio and this fixed the problems I was having. Getting great speeds now. But I'm far away from any 4G areas :/
I am having all kinds of problems today with the 3g icon going on and off. Sometimes when its on I still do not have data connectivity. Is this a verizon problem or just the new radio?
I think it has to do with LTE being prepped to roll out and more intensive stress-tests that they may be planning.
I've been having similar issues. I did the entire rooting process then flashed BAMF 1.5 and had little radio issues, but once I saw the 3G cut out a couple times yesterday, I flashed the radio that was already on my SD card. Since then it randomly cuts in and out, and sometimes requires a full phone reboot to come back. I don't think it's Verizon at all (at least not in my case), although my area is supposed to get 4G sometime this year.
I'm hoping the official OTA has a "better" radio that can fix these issues...since I sort of had issues like this in Boston when I was stock, but at home out in Central MA, 3G was as solid as ever.
Just an update in case anyone was reading this older thread--I continued to have signal issues for a day or two after rooting but I think I just had bad timing on flashing the new radio. I've spoken to a few Verizon customers (my mom included) and many of them had 3G issues the last couple days. Yesterday it was solid as a rock, signal better than I'm used to. So it probably was just a Verizon outage, testing 4G or whatever it was that they've been doing.
It's Verizon outages right now, lots of testing upgrading going on with VZW right now.

To all those with signal issues

I have noticed a good amount of threads popping up with people talking about signal issues, 3g/4g issues, connection issues or phone issues.
I was wondering if we could find out what the common factor here was and what fixes everyone has been using. I know that some people got new sim cars, problem solved. Some people restored to a full stock image via odin, problem solved. Reflashing the stock radio, problem solved.
So has anyone had any other solutions, issues or any other info regarding signal issues or anything relating to that?
Been through this with the Nexus, S3 and S4
The solution is to buy a Motorola RAZR or iphone.
Things that do not work -
Upgrading to the newest version of Android
Updating the Radio
Changing it to CDMA only
Lifting one leg up, putting one hand on your head and pointing your other hand due north
Attaching a sticker antenna to the back
Using some custom baked firmware
Reading posts from people who claimed they've solved the problem.
Using Bluetooth
Not using Bluetooth
Buying a special case
You can get a femtocell repeater if you are in an office or home where you get little reception but it won't help you on the road or just visiting a friend unless you want to set it up every place you are stationary.
In the end trying to fix the radio design flaw with a firmware update is about as useful as trying to fix a shattered TV screen by adjusting the brightness setting. If you read the radio issues on the Verizon Nexus and the Verizon S3 there are a lot of people claiming they solved it but in the end it still sucks.
I have zero issues with data on my s4 I'm on the east coast running clean rom 1.6.5 solid LTE everywhere..

Unfortunately this is very true, every other VZW Non-Samsung phone I've had hasn't exhibited this issue.
Motorola and Apple have had their share of radio/antenna issues as well.

I'm not really talking about comparing the signals to the iPhone or anything. I'm talking about finding a common denominator for the group of people that are suffering from signal, connectivity or phone loss on the s4.

Trying to tie it all together with a common denominator is a logical fallacy. It would be akin to trying to find a common denominator for everyone in the world that has a chronic cough. The causal factor varies from case to case.

The common denominator is we are on Verizon and have Samsung phones. If you want to go further, you could do a subset intersect and see we have the S4 on Verizon. It's like saying what is a common denominator for those people who have safety issues with the Chevy Corvair. It is a design flaw that only could be fixed by replacing the phone with a different model. Trust me, I went down this path with the Nexus and the S3 - magical firmware updates were dangled by fanboys saying they would come and fix the issue but the firmware updates came but they never fixed the issue.
If you want better signal, you could buy a different phone or get a femtocell repeater. TRUST me, I would love a magic bullet to fix the issue but there isn't one. On the plus side you'll get a ton of helpful posts from people saying they never have issues or you must be doing something wrong.
I dont know what is up with all ur phones, but my signal is much better than my old Galaxy Nexus/RAZR M. I am getting 2-3 more bars of 4G at work. At home it use to be only 3G, but now im getting at least 2 bars of 4G. I don't even turn on my WiFi anymore at home or work.
bars dont really mean much...
i have had some odd issues where i will be in home depot or grocery store trying to look something up and it will fail; market doesnt work, browser doesnt work. phone calls and texts (over gvoice so data) wont work.
the razM i had before this was solid. my GF still has the razrM and we were at grocery store other day and if you went the their app there was a coupon to add and the s4 was refusing all data again.
i had similar issues with an old HTC Dinc2 and it was then i started using an app "restart connections" to get data back but it doesnt fix the issue on the s4 i have. if i reboot the phone data comes back.
i have also twice now went to use gmaps and it it attempts to look up an address for 3-5 min and i finally restart the phone and go back in and find the address ASAP after reboot.
something funky is going on and i havent taken the time to try and look at syslogs yet...
i am running the stock MDK rom (rooted) on VZW
reception is odd

I'm in a difficult reception area in the middle of manhattan. Funny thing is that I almost always have 4G - even in my house. At the same time, I never have more than two bars of signal in my house. I have occasionally had trouble making calls (I think the tower I'm reaching is too busy), but once connected, no one has complained and dropped calls are rare.
I don't understand this and don't know whether to complain or not because although there are almost no bars, there is reception that is pretty good. So I've left well enough alone.
This phone gets decent reception for me. Dropping from 4g to 3g is new for me after coming from an htc rezound though. My rez NEVER dropped 4g in my city anywhere. Guess radios is the one thing htc can do right. My s4 drops to 3g in multiple areas sometimes. Hopefully Samsung keeps getting better with their radios and they'll have me as a customer for more years of they do

This is basically the same issue I have. Only a reboot/data toggle won't fix it. I had two bars(not that it means much, I didn't look at the db) and it kept saying it was communicating with the tower via the green/red up/down indicators, but I couldn't access any data services. I moved my car approximately 500 yards to the south and viola, data again. I don't get why I could make a call, but I couldn't access data.
That being said, it's still better than my Gnex for....well...everything. But I would say worse than my Rezound, Bionic.
i ended up flashing the modem with the ME7 version, while keeping the rest of the ROM on the original MDK. that was about amonth ago and i think ive only had to reboot 1-2 times because of data drop.

What is going on with Sprint Service

As some of you have probably read.
I gave up on the M9, mostly prompted by dropped calls, or calls going straight to voice mail.
I had the M9 replaced and gave it to my wife. It's been near perfect for her, she even dunked it and it's still running great.
My G4 is now doing the SAME thing. Although it has not dropped many calls, tons of calls go straight to voice mail.
Had a very important call this morning and even shutoff LTE, WIFI and Bluetooth and only had 3G on. And it went to voice mail.
The signal is not great, but should be fine for CDMA. Previous generation phones were fine (M8,M7, etc.)
I do see the signal bounce. Where it will be 3-4 bars one minute and none the next. The bouncing can be common in weak LTE (which is definitely weak).
But it's even bouncing with LTE off.
Even at home with two phones in the same location.
My wifes M9 will work, but my G4 will go to voice mail.
Where a couple months ago at home
My wifes M8 will work, but my M9 will go to voice mail.
Could their be something on the account that limits my phones? Like wrong bands or something. Not enabled for Spark but on a Spark Network.
As soon as Verizon gets the LG V10, I'm 99% sure I'm gonna switch. Don't know what else to do.
I don't really care for how locked down Verizon is, but I need a working phone.
This problem happens at multiple locations.
Any ideas appreciated.
I know this isn't specifically an M9 issue, but I know their are more experienced folks around here that might know something.
It is related to M9 TYPE phones though (Spark Generation 2-ish phones). It started when I switched from M8 to M9.
Upgrading my wife from M7 to M8 went fine and from M8 to M9 went fine.
Upgrading me from M8 to M9 went south and from M9 to G4 went south.
All SIM cards cam with respective phones.
All bought new.
All S-Off and/or rooted.
I may have found the answer. Read this !! It has to do with having WIFI on and phone going to sleep. Which is exactly what happens on G4 and M9.

I disagree...I'm using the opposite settings that he is saying to use & I've never had this issue (that I know of). I don't make alot of outgoing calls...most are incoming...I also have my work cell fwd'd to my M9 so I don't have to carry 2 devices...I'm on Wifi a majority of the time, I get calls & texts all the time w/ no issues...the only thing I have checked in Advanced WiFi is Wifi Optimization, Keep Wifi on during sleep set to always
Fix
------
The fix is to not have Wifi on when the phone is idle/sleep. change your Wifi settings below to the screenshot below.
Settings -- > Wifi -- > MORE -- > Advanced -- > "Keep Wi-Fi on during Sleep = Never"
I also have "Network notification" and "Always allow scanning" enabled.

Sprint did (in my opinion) a very poor job with how it handles calls. One of my favorite phones was the evo LTE which not only could do LTE and a call at the same time but if you weren't in 4G it could do SV-DO and work on 3G which it actually worked very well. Especially at the time when I had that phone, I hardly had 4G anywhere so being able to use data at the same time on 3G was great.
That said, that feature didn't stick around long. The m7 had a separate radio for LTE & 1X meaning you could surf at the same time because it had separate radios. This couldn't do 3G which was a step backwards however 4G was becoming more mature.
Fast forward to today and with your modern tri-band device while it supports multiple bands that the previous phones didn't, most people have no idea what that means they usually assuming if it's a 4G phone well then it's just that how is any different.
I have had plenty of people complain to me about calls going straight to voicemail or signal issues. Rather than having separate radios, Sprint just uses CSFB Circuit Switched fallback so when a call comes in, it lets the phone know via LTE and immediately switches back to 1X to grab the call. That said it's by no means perfect especially in a bad signal LTE area can cause issues. When I'm at home or work I usually set my phone to CDMA only since I have wi-fi there is no advantage to be on LTE, causes issues with calls coming through and wastes battery. Most users have no idea about what is actually going on so it's hard to explain to a friend why when a caller calls them, the caller might here 5-6 rings before the phone even goes off. Sprint's LTE signal frankly sucks in most places I go, even right next to the tower sometimes you won't get full signal.
Anyway if your wifes phone works fine in the same spot as your G and you are doing all your testing off of LTE and still having issues that tells me either you have a bad radio again or something is provisioned wrong. I would put the phone back to stock, reset the radio and reactive the phone then do some testing with calls off LTE again. If you still have issues at the point, I would swap the phone. My M9 is pretty good with CSFB, I haven't had too many issues with it but really I think it's a very poor solution how it works especially when your in a fridge LTE area with the phone bouncing in and out of LTE.
Once the network goes all LTE (god knows how long that will take) I think this will be a thing of the past but for now CSFB now it's here to stay. I don't see Sprint ever going back to separate radios like the previous gen phones as they would more likely be focused on voice over LTE instead.

It has not failed in 5 days since I flipped it.
It may depend on the WIFI it's on, IPV6 etc. I don't know.
I think this may have started the same time MMS started failing for SOME folks if WIFI was enabled. Disabling IPV6 on WIFI was a work around (which is disabled on your ROM).
But not everyone had this issue and depended on their router.
So their is weird sh$t happening due to Android changes.
I think this issue is related and not everyone runs into it.
I have had WIFI Calling setup, but disabled it on both M9 and G4 (because it's extremely unstable on every phone I've tried).
Not sure if that is part of it. Like my account knows it's WIFI Calling capable. But my wifes never had WIFI Calling setup, she also does not run WIFI at work. She's never had the problem (even with the same phone I had problems with).
Again I don't know the exact details, and this is not a fix. But disabling WIFI when asleep seems to have stopped it problem. But I need to go a bit longer to be 100% sure.
I've seen similar threads on many phones and carriers and many start off saying "Problem started with 5.x.x OTA update".
I think I was close when I thought it was the optimizer. And before I found that thread, I was testing with WIFI completely off (which also worked).
Something is a miss and there may be more "options" to cause the issue.

I think this may have started the same time MMS started failing for SOME folks if WIFI was enabled. Disabling IPV6 on WIFI was a work around (which is disabled on your ROM).
But not everyone had this issue and depended on their router.
So their is weird sh$t happening due to Android changes.
I think this issue is related and not everyone runs into it.
I have had WIFI Calling setup, but disabled it on both M9 and G4 (because it's extremely unstable on every phone I've tried).
Not sure if that is part of it. Like my account knows it's WIFI Calling capable. But my wifes never had WIFI Calling setup, she also does not run WIFI at work. She's never had the problem (even with the same phone I had problems with).
Again I don't know the exact details, and this is not a fix. But disabling WIFI when asleep seems to have stopped it problem. But I need to go a bit longer to be 100% sure.
I've seen similar threads on many phones and carriers and many start off saying "Problem started with 5.x.x OTA update".
I think I was close when I thought it was the optimizer. And before I found that thread, I was testing with WIFI completely off (which also worked).
Something is a miss and there may be more "options" to cause the issue.

I'd blame gremlins yes, weird sh*t...and yeah, we still have ipv6 disabled in ROM for wifi

Sprint did (in my opinion) a very poor job with how it handles calls. One of my favorite phones was the evo LTE which not only could do LTE and a call at the same time but if you weren't in 4G it could do SV-DO and work on 3G which it actually worked very well. Especially at the time when I had that phone, I hardly had 4G anywhere so being able to use data at the same time on 3G was great.
That said, that feature didn't stick around long. The m7 had a separate radio for LTE & 1X meaning you could surf at the same time because it had separate radios. This couldn't do 3G which was a step backwards however 4G was becoming more mature.
Fast forward to today and with your modern tri-band device while it supports multiple bands that the previous phones didn't, most people have no idea what that means they usually assuming if it's a 4G phone well then it's just that how is any different.
I have had plenty of people complain to me about calls going straight to voicemail or signal issues. Rather than having separate radios, Sprint just uses CSFB Circuit Switched fallback so when a call comes in, it lets the phone know via LTE and immediately switches back to 1X to grab the call. That said it's by no means perfect especially in a bad signal LTE area can cause issues. When I'm at home or work I usually set my phone to CDMA only since I have wi-fi there is no advantage to be on LTE, causes issues with calls coming through and wastes battery. Most users have no idea about what is actually going on so it's hard to explain to a friend why when a caller calls them, the caller might here 5-6 rings before the phone even goes off. Sprint's LTE signal frankly sucks in most places I go, even right next to the tower sometimes you won't get full signal.
Anyway if your wifes phone works fine in the same spot as your G and you are doing all your testing off of LTE and still having issues that tells me either you have a bad radio again or something is provisioned wrong. I would put the phone back to stock, reset the radio and reactive the phone then do some testing with calls off LTE again. If you still have issues at the point, I would swap the phone. My M9 is pretty good with CSFB, I haven't had too many issues with it but really I think it's a very poor solution how it works especially when your in a fridge LTE area with the phone bouncing in and out of LTE.
Once the network goes all LTE (god knows how long that will take) I think this will be a thing of the past but for now CSFB now it's here to stay. I don't see Sprint ever going back to separate radios like the previous gen phones as they would more likely be focused on voice over LTE instead.

I know about the call switching for LTE and it sucks. But that was not it. I tried CDMA only and it did not fix it.
Disabling WIFI while sleeping is still working. Not one call has gone to voice mail at work in over a week. It used to happen 2-3 times a day.
I HATE disabling wifi while asleep though. I'd like to still get to the bottom of it.
I think some how it is doing something over WIFI when a call comes in, if WIFI is available. But when the WIFI is in power save mode something gets messed up.
The problem started on OMJ's ROM with IPV6 disabled. So it's not that.
The only thing common is Lollipop, Sprint and my WIFI locations (and a modern single radio triband phone).
I'd like to try getting "WIFI Calling" capability off my account. I think once you set it up once, it's enabled automatically on my account.
I will also say, if I do enable WIFI Calling, it's terribly unreliable. Maybe that's a hint.
The WIFI signal is solid and no issues using WIFI itself.

Having Wi-Fi calling provisioned on your account is just that, it just means if you enable wi-fi calling that your phone has the green light to connect and move forward with the server. That said if you keep wi-fi calling off the fact that it is still provisioned on the account doesn't affect anything at all if the service is not active.
If you only solution is disabling wi-fi while sleeping something in the rom is borked. Return the phone to 100% stock, hard reset it (including the radio) then try using it again. While again CSFB isn't perfect, if the phone is CDMA only you just shouldn't be having this kind of issue. If your not having issues with other phones in the same area with calls going to vm, you know it's not the network and something with the phone. If it does this on 100% stock after a re provision then you have a borked radio and the phone should be swapped. Which I have seen borked radios before, the wi-fi radio in the phone is totally separate from the CDMA/LTE radio.

Did that, returned to stock, same issue. Got Another M9, same issue, got a LG G4 same issue. Just signed up for T-Mobile (have not canceled Sprint yet). Two LG V10's. T-Mobile just announced a huge expansion on their network to cover areas that I needed with LTE (Sprint roams 1x Lakes Region and North in NH).

Not a bad play, Sprint's Network has come along way in the past few years but with CSFB and a crappy LTE signal is most places they still have a lot of work to do. One of the reasons I stay is my plan and they are pretty friendly towards rooting/unlocking for the most part.

The V10 was awesome. T-Mobile was extremely good at My work, My wifes work, Home and all places between. Speeds were 4-8x faster (seriously) than Sprint. Simultaneous Voice and Data VoLTE.
But what the map showed up in NH, didn't match reality at all. Sprint is pretty dismal too, but they at least Roam and you can get 1x or 3G from either US Cellar or Verizon.
But T-Mobile had nothing in the areas Sprints Roams. So I'm sticking with Sprint for now.
I've concluded it's a combination of weak locations, the requirement to switch from LTE to CDMA for calls, and something around that is complicated by WIFI while asleep. Shutting off WIFI or shutting it off while asleep definitely improved things but didn't eliminate it completely. Both phones (M9 and G4) are Qualcomm chips and probably have similar Radio Firmware. But it's overly complicated due to Sprint being a bit behind the ball with VoLTE.
I agree Sprint is not quite so tight on locking things down. T-Mobile is the least locked down, then Sprint, then AT&T then Verizon. I know Verizon would perform flawlessly. But the combination of expense and being so locked down keeps me away. T-Mobile price was really good 2 lines 10GB each, with Carry Over and free Music/Video streaming. And the V10 already had TWRP on day one. The G4 on Sprint does not have TWRP and probably never will. It is rootable, barely.
I convinced my Sister to switch to T-Mobile because she wanted an iPhone and I recommended she not Jail Break it. But she wanted Tether (I was rooting Androids on Sprint for her). She is very happy with T-Mobile. And she generally stays in Eastern MA.
We'll see what HTC does this next time around. But they really need to step up their game. The reception issue really isn't an "HTC" issue. It's a Qualcomm/Sprint issue in my opinion. It's a kludge and I think Sprint is the only one with this kludge.

Will it work on AT&T

Hi
I wanted to buy this from gearbest.
Will it work on AT&T with all the LTE bands?

I'd like to say "yes", but have found out the hard way that it depends on exactly which part of AT&T's network you intend to use it on.
I created a thread which I haven't yet updated, which outlines some issues I had. Turns out that my X820 as well as a different LeEco X82X (can't remember - same model ) do NOT work with AT&T in my area at all, and I live very close to the antennae. However, when I travel out of town, the phones work great. AT&T can't seem to figure out why this part of their network is different, but something certainly is. YMMV.
At the moment, there doesn't seem to be a large enough sample size in the US to compare notes and find possible network issues with this phone.
I have it, and it works for me in North Florida in AT&T

I have more info on my issue with this phone on AT&T, and it's an odd one. LTE works great, but if I am directly under the antennae, or within line of site of them, 3G shows full bars, but it does not work and I cannot place or receive a call. If I walk a block away, and have a building between the phone and the antennae, 3G works perfectly. If I initiate a call where it works, I can move back to LOS, and call does not drop. No other phone seems to have this issue, so there is something very different in the 3G implementation in these phones which is responsible for this.
I wish someone out there had an idea as to what is causing this. One of AT&T's network engineers, who witnessed this first-hand, is stumped and I'm short on ideas to remedy it.

I got an x829 yesterday (live in the US) and plan on using it with Straight Talk/AT&T (getting the nano sim now). Have you flashed yours to a newer/custom ROM and it still works with AT&T? If so which ROM?

I have two of these phones, and both have the issue I described above. If I were to guess, it probably has something to do with initial 3G handshake timing.
One of the phones is running Madsurfer's 21s. It may have been a dirty flash over stock China ROM, but I seem to recall that one being a clean flash (wife's phone, so I don't mess with it much.) The other is Small EUI by aurel V7, dirty flashed over Rom V6-X820 of Bshuy2003.
I have observed no real differences with regard to the 3G connectivity issue between either phone, with any firmware. I'm thinking it is something at a lower level which is causing this odd issue.
I haven't received my max2 yet but I have read through allot of these posts and I remember reading about using the #*#* code to force LTE and it helped mobile connections. Also I saw that 19s CN or 17s India eui has VoLTE support. Lastly I noticed that the posted 23s beta cooked eui that Steve Mars posted has new modem files. You may try that as well. Hope that helps!

Thanks for the info, but I think the issue runs pretty deep inside these phones. If I knew more about the hierarchy of the software/firmware, where network negotiations are concerned, I'd have a better idea where to look for a solution. But I can say that I have tried virtually every ROM and modem file available, and this odd behavior persists. It's possible that it's specific to my home site, but according to the engineer, AT&T's sites are pretty standardized. The fact that other phones don't exhibit it, tends to point to something deep inside the Max2 as being the culprit. It's an insidious problem, as one might not realize that there was an issue, unless one happens to be close to a tower, trying to unsuccessfully make or receive a call, with full bars showing.
IIRC, the iPhone also had some strange issues on the AT&T network in the early days, and it took some concerted effort between AT&T and Apple to get it sorted out. The chances of of something like that happening to solve issues with these phones is probably next to nil.
Randy do you have LTE on your account? Could it be the eNode trying to promote you onto a better link and the baseband failing that negotiation?

I do have LTE on my account. The phone is connected, by default, to LTE, and falls back to WCDMA when making a call as it should. I have monitored signal strengths throughout the process, and they are very high, due to to my proximity to the tower. Locking the phone to WCDMA makes no difference.
When the phone doesn't have line-of-sight to the tower, and/or that LOS is significantly obscured, the UMTS signal goes below -60dba and the phone works perfectly. Thinking the signal strength was the key, the output of the tower was artificially reduced to below that level, as a troubleshooting test. It still did not allow the phones to work on WCDMA to make calls, even though it still showed a 3G connection with full bars. I'm not a telcom engineer, but it really seems like a timing problem, where the reflected signals work, but signals received directly from the transmitter do not. Again, the problem exists only at the point where the 3G link is initiated, either by the handset or the tower. Once a call is established, that session works fine, no matter the proximity to the tower thereafter. But once moved into the areas of LOS to the tower with an active call session and I end the call, the phone can no longer make or receive calls in those areas.
Short answer: sorta

Alright so I have been using this phone for about 6 months and it kinda sorta does. I am using the x820 one btw. I get about 80% up time with this phone. I can't really make or receive calls without the phone dropping them within the 1st minute. Let me explain further. So firstly, when I am on LTE (if not on 4G (I'll explain later)), and try and make a call, I will usually get switched over to 4G and then as the call is attempting it will completely lose service and say I can't complete the call. Then after that attempt, I will usually get my service back. And it will keep doing that unless I get lucky then if I actually can make a call then I will be lucky if I get a full minute or 2 before the call drops because of loss of service. Now for the later explanation. So basically I have noticed just because I am supposed to get LTE doesn't mean you will get the service. Also you will drop service a bunch and it gets very aggravating! I have verified my results in FL, GA, and TN.
