[Q] EVDO <failed>

A few weeks ago my evos data became ridiculously slow. I was the latest stable cm6 (6.1.2 iirc) and it was out of nowhere since I did not install any new apps or make any changes. I did a nandroid back to when I first rooted and I still had no 3g (wifi, bluetooth, wimax, 1x all work).
The tech I talked to at Sprint had me try updating everything and even a factory reset (which I already tried before calling). I have Best Buys phone insurance (never again. Sprints is much better after having to use both at one point or another) so I took it to best buy and when I get my phone home the data and phone are slow. After a few days I notice in ##debug# evdo engineering has <failed> on everything and I was running 3.26.xx.x I just ran the ruu to the latest 3.70 and it is snappy again but still no 3g.
Once I get time I am going to take it to the sprint repair center but I am curious if anyone else has had this problem. A search on here and Google doesn't come up with anything.

Have you tried updating your profile? Also, are your radio/baseband, PRI, NV & WiMax files updated to the latest versions? You can check it by going to Menu-Settings-About Phone-Software Information. The NV will not be listed, by the way.

Yes, everything is the latest. I even tried the port and proxy reset to 0 and 0.0.0.0 respectively method with no change.
It seems like my radio just doesn't work on 3g anymore. I hope to get to the sprint service center before the weekend.

I hear ya. Hopefully, they'll provide you with a new EVO instead of a refurbished one.

Call sprint's advanced tech support.
877-809-6696 ats advanced tech supp
Ask them to do a full profile reset or update. They ask you to power the phone off for a few min (they even asked me to pull the battery, but I didn't see a need for that). Then when it reboots, it will do the ota provisioning, which should correct things.

They did that as well. The tech said it was basically like a new line.
It is odd because every other thread I see online has had it fixed by one of the common methods or by calling sprint.
I have a tux fitting tomorrow for my brothers wedding and the sprint service center isn't too far from that so I should be able to get it checked out then.

It may be Sprint and their network. A lot of people have been stating that they are either getting really fast speeds or really slow speeds. If I understood everything correctly I think that Sprint is going through several updates for a while to be more competitive and provide better service. It may not be your phone. If you have any friends with the same phone then does a speed test to the same server side by side and see if that is different. If the results are the same it is the network, but if the other phone is faster then it is your phone that is having the problems.

My friends evo is perfect right next to mine in san jose to sacramento. I have no 3g anywhere I have been lately (Monterey all the way to South Lake Tahoe).

I was having the Same Issue with my wife phone but she was running CM7 RC2. I was able only fix it by installing sprint Lover.

Then as itohead said try to install Sprint Lovers and see if that works. If not then I think that there is something wrong with your phone and you may need a new one, or wait till the Evo 3D comes out and get one of those.

I forgot to update this. Sorry guys.
Took it to a sprint repair center and the tech said he's never seen that before and ordered me a new one on the grounds that my usb port was "broken".

Learnt something about Canadian LTE from a buddy who works for a carrier here

So I was enjoying a cigar with a buddy who is a field tech for a Canadian carrier (not mine rogers, but another one) when we got on the topic of a samsung tablet work issued him.
He said he uses it to troubleshoot LTE issues they've been having.
Basicly the device loses LTE and either goes into "no service" or get's stuck in HSPA+.
I freaked because i've noticed the same issue, but thought it was related to CM10 running on my phone.
Apparently they discovered it has to do with they're infrastructure. The phone loses LTE, tries to re-negotiate,gets rejected, and stops trying.
They're work around is to get firmware updates to get the devices (he didn't mention which ones) to re-negotiate a second (or third time) where it almost always goes through.
I just reboot or bounce air plane mode and it often works.
Just figured people might find that interesting.

Bell has had the same issue (for a while), I haven't received any calls about it recently but also didn't receive an email about it being resolved but it appears so. Our temporary resolution for it was to just keep it at H+ for the time being
Found where I posted about it here

When I bought my S3 at the Bell store here in Québec city a few weeks ago, the salesmen insisted on NOT giving me a LTE sim card.
What he told me conquers with what you are describing.
I accepted is suggestion and got a H+ micro sim.
Since then, I returned to the store to get a LTE sim card and I did encounter the issue once or twice.
I am now forcing my phone to remain on H+ at best via Settings > Wireless & networks > Mobile networks > Network mode.

In the greater HRM (Halifax/Dartmouth/Bedford) we have a pretty good LTE footprint according to the Rogers website, but my S3 is constantly reconnecting. I can tell because every time it drops LTE, my visual voicemail app will notify that it has no service.
I turned LTE off because it was just hammering my battery. I could barely make it through a 10 hour work day with little to no usage if I leave LTE on, and I'm supposedly in the middle of the service area.

Off topic: CM10 has awesome battery life with LTE i find

I first read about LTE causing loss of service several months ago. I returned my first SIII because of it and the replacement phone would also loose service randomly. So now if I want to be assured that my phone is working when I really need it to, I have to disable LTE. Seems like more people need to know this since for some people it is important to know that your phone hasn't just decided to go into NO SERVICE mode without warning.
I'm told service providers were, until recently, strongly denying there is any such problem with LTE. It wasn't until the iphone5 came out with the same issue that this became a real problem for customer service.

Not sure if this is the same issue, but I sometimes receive a "not registered on network" or "sim not registered" when phone switches from LTE to 4G or comes back after being in a no service area.
A tech calls me once a week to track the issue and he told me last week they put out a fix for eastern canada and will soon do the same out west if it works. This is Telus by the way.
If you are running into what I mentioned all you have to do is switch to GSM/HSPA Auto mode under - settings/more settings/mobile network/network mode.
Of course you won't have LTE but its a reliable temp solution if you require consistent service.

MTS LTE
I've heard similar from MTS about their LTE!
My Galaxy S3 works fine on LTE, but my brother's S2 LTE never seems to display LTE on the screen, just says 4G all the time, yet speed test results indicate it really IS LTE! The first 2 weeks, his phone kept dropping to NO SERVICE randomly, but more often than not! We swapped out the LTE SIM on day 2 since the first seemed to be defective. After that, I updated the S2 to the latest release OS which seemed to have remove SOME of the issues.
From what I've heard, the LTE towers need the phone to be quiet on network activity for 20 seconds or so before it will attempt to jump back onto LTE. The S3, being much faster, doesn't seem to have issues flipping around as it needs. I'm told they are deciding which software/firmware to upgrade their towers too which will hopefully happen early 2013!
So I'm wondering if this might be the same issue with other carriers, where the problem is ACTUALLY with the towers and not devices?!

Not that stupid as I, like I said, did experience the issue since I got my LTE sim card.
But to answer your question, no I did not have to pay for the new sim card.

I've done the same. I find "4G" fast enough for the most part, so I just leave LTE off for the gain in battery life.
Also in Halifax I might add!

St Louis LTE AT&T issues

For about a month now I have been having problems with S3. Sometimes have to place a call 4-5 times before it will go through. Receiving calls is a mess, it either says I am unavailable or it goes straight to voicemail. The real kicker was that I was not able to get data during a call.
Today I created a new APN for wap.cingular to force it to HSPA+ and bam everything is working great. Calls go right through and I can do data during calls. I have been on AT&T about this and they said they have opened a ticket but you know how that goes. I do have a friend that works in the business and she did forward me this email.
Team, there is a network issue in the St Louis area. Please read below.
***NETWORK ISSUE ALERT***
Company Owned Retail, Local Dealer, January 8, 2013
National Retail, and Small Business in the
St. Louis LTE coverage area only
Network Issue in St. Louis LTE Coverage Area
Overview
Customers within the St. Louis LTE coverage area may be experiencing missed calls/sudden voicemails. This issue is being reported as an intermittent issue primarily impacting Android 4.0 and 4.1 handsets although there are a few reports indicating Windows devices are being impacted as well. The local and regional network teams are working to resolve the issue and further details will be provided as they become available.
Action Required
1. Please do not swap out the customer’s device as this will not fix this issue.
2. Share this information with all team members.

Ok so I had an S3 that had this issue. Went to AT&T and they told me this. This is NOT satisfactory to me as this is a HUGE issue.
SO I went here: http://forums.att.com/t5/Android-Di...for-the-Galaxy-S3-Saves-a-lot-of/td-p/3326169
Followed the directions to turn OFF LTE. I rebooted the phone. Followed directions and turned LTE back ON and then rebooted again.
NOW I have working faux 4G during a call and I don't miss any calls, nor do I have to dial a few times before a call goes through.

This worked for me too. Its almost like the phone needs to re-register with the LTE network. I dont know why they arent telling their reps about this.

LTE has been fading out in Fenton as well. I have to flip to airplane mode and then back out of airplane mode to get 4G to become 4GLTE.

[Q] Data service iffy on LTE - phone or Straight Talk issue

Hi,
I've been having data issues with my HTC ONE M8 on Straight Talk for the past couple of weeks. the data service for some reasons got really iffy. before everything was absolutely fine. now sometimes I cannot access data at all, sometimes something is working and something doesn't.
when the data doesn't work:
- most of websites are not reachable
- google.com seems to work normally
- google maps might work; sometimes very slow, sometimes not working at all
- ookla speedtest won't start, but if I set a fixed server it might work
- facebook.com might work in the browser but the app doesn't work
- refreshing the page seems to help
on WI-FI I have absolutely no problem. everything works fine.
phone and txt messages work without problems.
on 3G (HSDPA) everything seems to work fine. I see problems when on LTE.
anybody has the similar issues?? any suggestions?
many thank!!

I am having the exact same issue! So frustrating, I don't want to use 3g if we should be on "Full speed 4G LTE for up to 3GB"!
tried so many different APN's, no luck can't get over 2.5mbps with any of them

I would be happy with anything that works right now. the service is just NOT WORKING. I am paying for a service that doesn't work and that's not acceptable.
I opened a case with the help desk; useless. I was talking to people who don't understand the basic concepts of networking. made me add a proxy to the APN; no difference at all.
then I put a complain on Twitter and got some other people "helping" via email. at least they asked for the address of where I am always having problems; hopefully, they check out the service at the antenna. I think it's not a BTS (antenna) issue but something related to their proxy, firewall or network gateway since google.com works without problems!
I talked to a friend of mine who has StraightTalk as well and he said that he had the same issue last year!

I had the exact same issue with Net10 it is so annoying and unacceptable =(

Have you tried calling straight talk a call

U can try this from what I know ur phone gets chooses the strongest signal tower example u are around 3G tower it has a 9/10 signal and the 4g tower is a 6/10 strength it goes with the 3g hope this helps in ur dial pad dial *#*#4636#*#* then Phone Information....Scroll down a little bit to Set preferred network type. I was able to lock in LTE only doing this and gave me the fastest signal on my device hope with works for u. If u can post ur original settings before u change to lte option only on this post so u can always revert to ur original setting good luck.

if I lock it to 3G it actually works well. I will try your suggested settings.
on another note I wonder if it's an issue with the phone radio implementation. my Nokia/Windows phone sees LTE very very slow but it doesn't stop working completely.

Hmmm Idk but anything's worth a try what settings do u have it on already?

if I put it on GSM/WCDMA (so no LTE) data works fine in 3G.
and if I do a speed test in 3G it gets about 5Mbps in download vs 1, 2 or 3 Mbps when LTE works (ZERO otherwise)

The exact same thing started happening to me two or three weeks ago. More often than not, the LTE connection simply doesn't work, and when it does, it's excruciatingly slow (anywhere from 0.01 to 2.50 mpbs, and usually less than 1.00). Do you guys have AT&T or T-Mo sims? I'm starting to wonder if going to Cricket would solve the problem, but since I'm running an AT&T sim, I'm not sure if anything would change since it's on the same network.
Straight Talk support is worthless... they think a factory data reset will fix it, when it's clearly a network issue. I just told them to stop right there and started troubleshooting myself. That's a good tip about dialing *#*#4636#*#* and turning off LTE that way. It seems like that is where the issue lies - I'm having good luck with HSPA; it's slower than LTE should be, but at least it works. It'll do as a stopgap through the end of my billing cycle, at which point I can decide whether to go somewhere else or get by on HSPA until they fix whatever the problem is.

tried and on pure LTE it simply doesn't work. the only way is to set GSM/WCDMA and it goes at 3G speeds but at least it works.
the funny part is that Google.com always works, whatsapp works, googleplay works. so it seems a problem with throttling or filtering to me.

I have ST on AT&T.
a friend of mine with iPhone 6 down in Newport has no problems. he sent me screenshots of speed test at 15Mbps.
I really wonder if it's some radio firmware issue...

Ironically, I ran into something very like this too recently....I was on an at&t straighttalk sim...lte had been OK prior to me updating to 4.4.4. It was never spectacular, but it was, at least, lte speeds. After the update I noticed it had become really sketchy...just as described, pretty much; even when mine worked it was trash. 3g was much better and totally stable. I thought it might be the update, but long story short, it wasn't. I inserted a friend's sim from tmobile and got full lte with no issues.
Now, in my case, I had been using a shaved down microsim rather than a nano sim, so I thought, maybe that's the issue. I noticed when ordering the new one, the tmobile one actually said htc m8 compatible on the page(plus my friend's legit tmobile sim got good signal and lte so I thought that's a good basis for comparison). Got the new one, put my number on it, and voila! I'm getting on average 20mbps lte. And it's very consistent too. So now I'm on the tmobile straighttalk sim and everything is fine.
Anyways, it's only $7 with free overnight shipping, so that's something easy to try. This wouldn't be the first time a new sim fixed all sorts of weird data problems with straighttalk either. I've been on with them for several years now and this is probably my 4-5th sim I've had to get for various reasons.
So, anyways, your mileage may vary but that fixed it for me. Hope it helps.

it seems ST on T-mobile is not having the same issues as ST on AT&T. the problem is that T-mobile coverage is not so good in my area.
I tried my phone in a different location (400 miles away) and had the same issues.

I've done some more testing.
it is really weird that Google.com works flawless while any other site seems not to work.
activating "save data usage" in Chrome seems to help. however it doesn't solve the problem. sometimes pages needs to be reloaded a few times.
even when LTE works, the OOKLA speed test gives me 2Mbps in dowload and 5-6Mbps in upload. so no matter what, I am better off with 3G.

I found an interesting thread here on XDA. I am not rooted at the moment and can't try.
<<
If you are rooted there is simple FIX, simple disable FD8 (Fast dormacy 8)
ro.ril.enable.r8fd=1
ro.ril.enable.pre_r8fd=1
Change both to =0 and issue will be fixed.
If your not rooted only fix is to keep HotSpot enabled than data connection wont break.
>>
I tried the hotspot trick but it doesn't work for me

Sorry to bump an old thread, but I just wanted to give a brief update. My LTE issues with Straight Talk went unresolved for about 6 weeks despite multiple conversations with customer service. I experienced this in Raleigh, NC, Greensboro, NC, and Virginia Beach, VA. Then for Thanksgiving, I went to New York City and New Jersey (the part just outside of Philly), where all data connections were unreliable. Yes, that means 2G, 3G, HSPA, and LTE were all spotty at best the entire time.
I ran out of patience after that, and since my billing cycle was ending on 12/4, I switched to Cricket when I got home. As soon as I popped in the Cricket sim card, everything started working flawlessly again. Cricket does limit you to 8 mbps down, but that's good enough for my purposes. The issue, if it's still going on, is with Straight Talk and not the phone.

Lollipop Fixed the Issue on my HTC M8
Hey all,
I've been following this thread as I too had issues with LTE on my HTC M8 using StraightTalk. When I first got my phone, it worked perfectly with LTE on ST. Then I ran the OS update that was released sometime near November. That's when I noticed the problems. I could run a search on Google but any webpage I would try to connect to would not load. The phone would hang and eventually time out. Your instructions to turn off LTE was great help. Pages load perfectly provided LTE is not used. I was getting really frustrated and you kept me from throwing my phone at a wall. Thanks for that.
So that brings me to this post. I updated my phone to Lollipop this morning. Thought I'd give turning LTE back on and bam.... works perfectly. I've been testing it all morning and so far, all pages load really fast. I will keep an eye on it for a while and post any updates but thought I pay it back a bit with the good news since you guys helped me.
Thanks again.
AC

thank you for sharing!!
trying to upgrade to Lollipop. unfortunately I am having an issue with the recovery (flashed from TWRP to a stock that doesn't work with the OTA and can't flash any other recovery -not sure what's wrong).
when I solve this issue and able to upgrade to Lollipop I will share my LTE test results

AT&T tech support said my OP7T not LTE Compatible

It's HD1907 T-MOBILE. What I need is HD1905. He sent me the wrong one.
I only realized a few hours ago I had no mobile data. I had got calls and texts to work this morning.
After spending 45 minutes on the phone with AT&T they concluded my phone is not recognized as LTE compatible. WTF? It's not even connecting to 3g.lb
I've been buying unlocked phones for years. My last phone was OP5T. I've never experienced anything like this.
I'll probably take it to the corporate store tomorrow but doubt it'll help. Has anyone had problems with AT&T and this phone?
I'm just putting it out there, hoping somebody has an idea...

AT&T worked for me, excellent data speeds, and great signal. But at times it would go from 4 bars to absolutely no signal or data, and lots of dropped calls. After that I went to Verizon, not as good of signal, slower data, but no dropped phone calls or mysterious total loss of signal in an area where it should have been 4 bars.

I'll bet if you look in the settings your model is HD1905 or the global model, not sure the number.
Actually if you could take a look for me and post back here that'd be good. It most likely won't make a difference but I'm curious.

Yes I have the HD1905, but you can totally forget about vowifi with any provider except for T-Mobile. I tried them all, I even had a tech from VZW work diligently to try and get vowifi working. I told him to try and add my IMEI to the approved list, and that did not work either. As far as AT&T, they did not give me the time of day, they just told me I needed and AT&T device, period.

You mean Verizon when you say VZW?
I'm just confused as to how he would be able to add it to the list of approved devices.
Anyway it's BS. If the carrier supports the phone, and the phone is capable of VOLT!/WIFI CALLING, it should work.

Yes Verizon. I have heard hear many times on this site, that phones are blocked from wifi calling by the IMEI, I or they could be wrong.
Vowifi works on the unlocked Pixel, but are they going to butt heads with Google? Volte works fine, I got a network extender, and I can use google voice to make calls over wifi if I really need to.
If vowifi is a must, get an approved phone, that is all you can do.

I worked at AT&T until a few months ago. I can tell you confidently that their tech support is a bunch of dummies. Employees have their own tech support line to call and that one is just as bad. They would routinely tell customers they needed to go to a store to have something done. Then they'd get to the store to find out we literally cannot do that at the store. Stuff like that was super common. One of them even bet me $1,000 that iPhones DON'T reboot when they update, which we all know is all the way wrong.
I halfway think support tells people that stuff on purpose to try to get them to buy something from AT&T. God, I could rant about that place for hours lol

Maybe you can answer this for me. Just because a T-MOBILE locked phone is able to make calls and texts on AT&T, does that automatically mean it should be able to connect to mobile data?
I was able to get it to make calls after a refresh signal was sent out, but it could not connect to mobile data . My sim is fine. I even popped it my son's Pixel 3a and LTE started immediately.
The seller is saying the fact that it was able to make calls means it is able to connect to mobile data. And I should take it to AT&T before returning it. I don't think he's scamming. He says he has the same phone on AT&T. And he's sold Hundreds of them. That kinda checks out based on reviews and some of those people do report it works with AT&T.
These phones are hd1907 T-Mobile but supposedly OnePlus unlocks them before sending them out to some sellers. I sort of believe the guy but is it true? If it were locked to T-Mobile could I get it to make phone calls?
Obviously I'm not talking about a hack. Because I thought locked was locked. Is it possible for a locked T-Mobile phone to make calls on the AT&T network?
Also I got AT&T to make it work but once I removed the sim/reinsert it, the thing displays weird behavior. Wifi goes in and out. It forgets the apn settings that were set prior.

I agree, ATT was the most horrible experience I ever had. Tracfone may have even had a better customer support.
Verizon CDMA service may be antiquated, but their customer service and tech support is 2nd to none.

It should have no trouble using data BUT you'll have to change the phone's APN settings to match your carrier before you can. You can google it and find them. It's not hard at all to change. Somewhere under the "network" settings.
Someone correct me if I'm wrong, but as I've understood it the phone will keep trying to access the previous carrier's data network, which is why you didn't have data. But as said above the APN settings should fix that.

If I told you the whole story, which started on Friday morning and in the end involved 7 AT&T employees, 6 on the phone and 1 in the store, it'd probably be removed because it's spam. Too long of a story.
But in the end it didn't get to connect to mobile data..at least not consistently. I took it to the store. The guy removed the Sim reset it, turned it off and boom! - LTE, calls and texts. His theory was it takes a little while for it to unlock and get set so when I tried it the other night it wasn't working.
I was happy because it literally took 5 minutes. I ran some errands and was out for like another 2 hours. Everything was working. Some point between the store and my driveway, the signal was gone. I never got it back. Of course I tried reset, remove Sim, reboot, change apn settings.
I called AT&T... the first woman didn't even know what CDMA and GSM was. I politely got her to transfer me to the guy who 'knows his stuff'. He got it to make calls again, but in the end concluded this device can't work on this network. I didn't wanna argue anymore. He had a BS answer for everything including 'If it doesn't work, why DID it work just a half hour ago?'
He said I could try getting a new sim. They have no idea. My son's sim won't work on this phone but pop it in my old phone and it works. And my sim works in his phone. It's not the sim. I know it.

I took it back to AT&T yesterday. There was someone in front of me so I sat down, removed the sim from my working phone, popped it in the op7t... instant lte, calls & texts. The same thing happened the day before I went to at&t. It worked perfectly well there in the store and even 2 towns away but not m my neighborhood which DOES connect to LTE, has for years on every phone we've had.
The tech (if you can really call him that) updated the sim. That got it done. I've had a working phone for 24 hours. BUT no LTE. It only connects to H+.
I haven't had time to call or go back to the store, but I'm hoping it's an easy fix. This has been the weirdest week I've ever had dealing with a phone. I've learned that AT&T doesn't know what they're doing. I still can't believe I needed to explain what GSM and CDMA was to one of the people on the call.
I'm gonna try a few things tonight after work.

Thanks for sharing, but I've never really needed to mess around with the settings as far as mobile data goes. It either works out of the box, or at most I'll need to put the apn in manually on some custom roms, but even that's rare.
How does the info you provided apply to my problem. I know the phone can connect to lte. It was connecting briefly on Monday afternoon and while I was at At&T yesterday, it connected before they updated the sim.
Is there something I can do with this? It's a sincere question. I'm not sure if I can apply it somehow. Thanks

I think his point was to show that the OP7T does in fact work on all AT&T bands. Normally you don't need to do anything with this if the SIM is provisioned correctly.
What are the chances that you are on the edge of the local AT&T LTE signal so it drops to H+ because that's a stronger connection? At the AT&T store the LTE signal is stronger so the phone is favoring that one. Some phones are more sensitive to signals than others (or more aggressive at switching to a stronger band).
Try using a program like "LTE Discovery" and see what bands you actually are connecting to. It can also let you know what is going on in your area with tower location.

I'll try that. Thanks.
That's what I said but the guy at the store said it's really not a stronger signal at the store. Plus I know I can get LTE at my house and in the store because all our other phones connect, even this one, briefly at the at&t store.
The seller have me a code to input into the dialer but I'm waiting for tomorrow to put it in. It's my day off. If something goes wrong it won't be a huge deal. I will look into what you sent at some point though.

Your posts are bouncing between VoLTE & VoWiFi.
LTE bands and VoLTE work fine on Verizon's network.
Verizon allows VoWiFi on the OP 8's that they sell. They will not activate VoWiFi on the OP 7 series, the claim is that the phone did not go through their security testing. IIRC VZW doesn't allow VoWiFi on any outside phone.
