[Q] 4G turning on and off, slowing down phone

So I wanted to try out different kernels yesterday. I'm rooted using the Stock ROM.
My phone was already running netanarchy's 4.1.9.1 with no problems, but I wanted to try out King's kernel BFS #8 as well as #6. I did a cache and dalvik wipe prior to each flash. In the end, I deemed that I personally like netanarchy's kernels more, so I switched back to 4.1.9.1.
However, now my 4G keeps turning on and off. This is causing my phone to significantly lag in intervals correlating with the on and off of the 4G toggle. Is it possible that flashing different kernels somehow borked my wimax radio?
Any help is much appreciated.

Is it anything like I described here:
http://forum.xda-developers.com/showthread.php?p=8052344
I'm having this issue and I never even rooted my phone. Note my latest reply that I did a hard reset on one of the evo's and now the 4g radio hangs on "turning on..." when I try to turn it on. Still seeing that now. Considering doing the unrevoked 3.2 to root it and try to fix it since sprint is clueless on the issue.

Yea, it is similar to your issue. I found your thread after I posted mine. I tried updating to the latest Wimax update found on XDA and that helped somewhat.
My 4G stays on, scans, and says connecting to Sprint network. However, it never successfully connects. I now believe I have the dreaded MAC address problem and am now trying to fix it.

I can't even see my 4G MAC address because I can't get the 4G radio to turn on. How else can I check whether my keys are screwed up (without being rooted)?

try dialing ##3282# and select view mode. Go to WiMax and look under NIA. That should have the MAC address.
If it does not match what is listed on your box, then your MAC addresses do not match.

You gotta be rooted to do that. As for your keys getting hammered, the key issue arises on rooted phones after a bad flash, or corrupted radio file. More than likely your keys are fine. Let me ask you this, have you previously have 4G working, and it just stopped working? Or you now just tried to use it, and it's not working?

Yes, it used to work. I picked up signal around the boston area a month or two ago (before boston officially had 4g). I can't remember whether I used 4g successfully after the 2.2 upgrade. I was part of the group that did the .3 leaked 2.2 update and then took the .3 to .6 update OTA. I have never rooted this phone.

There is no WiMax option when I do this. I think the WiMax radio needs to be switched on to see this. But I can't get the radio to turn on.
I've been using alogcat to try to debug the issue. I see this error come up about 90 seconds after trying to enable 4G (this is the same time the "turning on..." changes to "Unable to start 4g"):
E/WimaxStateTracker( 104): Failed to load Wimax driver -=>wl.release
I haven't been able to find any information about what this might mean.

same problem here; ever since running unrevoked 3 the other day, my evo 4g keeps turning 4G on and off by itself, and, wont let me stop it from doing that..
its killing my battery with its constant searching, and I cant find any sort of "tweak" that will allow me to just shut it off or leave it on; the widgets dont do it, so I cant figure out how to stop it..
was working fine before this..
On stock 2.2 froyo, stock kernel...
any ideas?
thanks!

Ok you may have hammered your 4G then. I've heard of a couple of people who took the leaked update, and fouled up their 4G. I would suggest you backup your stuff then run the latest RUU to see if that clears things up with the wimax driver not loading. If not take the phone to Sprint.

i read the thread you started about this issue. you mentioned you were having trouble breaking the on/off loop but then mentioned your wife somehow was able to do it. while in the on/off loop, did you find that the the radio was actually spending any time "scanning" after it turned on? on one of my evos, the phone would switch from on to off and back to on so quickly, the button was always grayed out in the wireless menu so i could never interrupt it. on my other evo, it would spend a little time scanning ( a second or 2), which was enough time to press the button so the 4g would turn off for good and break the on/off loop. a hard reset fixed the phone with the unbreakable loop (4g now works). a hard reset caused the other phone to change so that 4g just hangs at "turning on..." when i try to toggle it on.

By running the latest RUU, do you mean perform the latest OTA sprint update (the .6) by putting in on my SD card and doing the volume down/power button trick? Is this safe if I already have the update applied? I was considering doing this but wasn't sure if it would be safe to do.

is it possible??

Hey guys, I have had a problem recently devolop on my phone, regarding 4g. First, I will start by saying that I have read just about everything I can read regarding broken 4g, but find nothing pertaining to my specific issue. Secondly, is there anyone is the Las Vegas area having issues connecting to 4g? Next, here is quick run down of the issue. I use 4g daily, all the time. I have never had an issue with it. I am currently using Myn's warm two point two, RLS2, on kings #11. Never had an issue with 4g, no matter what ROM i've used actually. I have NEVER flashed a wimax update. I have flashed a radio update, maybe a month ago or so. So I was tethering while on 4g, and I downloaded a modified "sexy" rosy, with the browser button on it. I then booted to recovery, wiped cache and davlik, then flashed the rosie zip and rebooted. Everything seemed fine, rosie worked, and all was well. Then I went to turn on 4g, and it won't connect. Just says scanning, connecting to sprint, disconnected, scanning, connecting to sprint, disconnected. After trying a billion times, once I got it to connect, for about 10 seconds, i had great 4g signal (as i always did prior to this) then it kicked back to 3g, and was continuing its scanning loop. So i restored my nandroid backup (which I made right before I flashed that rosie zip, while 4g was working) and I still have the same problem. So, my question is, is it possible to screw up the RSA keys, having not even flashed a wimax radio update? Or am i just experiencing some insane coincidence, that this started happening immediately after flashing that rosie zip. I am not sure how much troubleshooting i should put into this, seeing as I dont see how its possible that flashing that zip could've screwed up my 4g RSA keys. I am not sure how to figure out if it's my phone or sprint's network that is the problem. I have read some threads on how to check if the RSA keys are still in tact, which I will probably try to test that later, but I have never used a command prompt, or ADB shell before. I guess it's time for to read up on that and learn how to do it. I get confused about if I'm supposed to be doing these commands from the phone or my PC. Does anyone have any opinions, suggestions, ideas, insight? Anything? Any pointers would be super appreciated. Thanks fellas.

Sounds like 4g network went down. Can't be anything else if you were able to actually connect even though it was only for a brief moment.

Thanks for the reply. That is certainly what I am hoping. I used root explorer to look at my MAC address, via data/misc/wimax and the number it provides me with matches the number under my battery, so I believe that is a good thing. One of the post's I read, regarding this issue, said to rename that number (xxxxxxx.tree.xml) to xxxxxxxx.tree.xml.old. I'm not exactly sure what that will do, or if I should try it. I am hesitant to play with things I dont know about (yet). Any further suggestions or opinions? If I were to call sprint, would they tell me if 4g was down in my area? We did have 4 straight days with some pretty insane and sporrattic lightning storms. Perhaps something got damaged.

thanks
So it turns out 4g is down near my house. I'm on 4g right now, just in a different part of town. Sorry for wasting the thread space. Thanks again

Broken Wimax on Sprint

First off, yes, I have used search and have read any thread where people said they could not get 4G to connect. I have used google to search for a solution as well. I am posting this with that hope that someone may have an insight and if I can resolve my issues hopefully others will be able to as well.
The Problem: My EVO will not connect to 4G service. It turns on, goes to scanning, connecting to sprint, authenticating to sprint, obtaining IP address, disconnecting, scanning, connecting to sprint, …
The History: I have always kept nandroids of pretty much everything I do on my EVO. I have nandroid backups from the first time I rooted my phone still hanging around. I have used nothing but AMon-Ra 1.8 and later recoveries and made sure that the wimax partition was backed up. The week before last my EVO connected fine with 4G. Last week Myn updated to RLS5 and naturally I ran out and updated it. Unfortunately I don’t have 4G coverage (or 3G or 1x for that matter) where I live so I didn’t notice that my 4G stopped working until I got to Salt Lake City. I figured it must be something to do with the Wimax towers in the area so I wrote it off. I have had that happen in various places that didn’t have official Wimax roll-out yet. When I got to Seattle it was still doing the same thing, that is when I started to get concerned. So I sat in a parking lot where I knew there was great 4G coverage (my laptop has a wimax radio in it so I could see the good coverage from Sprint) and proceeded to roll back to a version that I know worked. No good, still no 4G connection. That is when I started digging through everything I could find.
The Troubleshooting process: First thing I thought was that maybe I had whacked my MAC address. So I ran to XDA forums, checked out the post on how to check if my MAC is still good. MAC address reported by fastboot oem wimaxrmac is the same as the one under my battery. Maybe I whacked my keys? Again, ran to XDA forums and found that I can run ‘cat /dev/mtd/mtd0 | grep RSA’ and see if my keys are there. Sure enough ----BEGIN RSA PRIVATE KEY---- and ----END RSA PRIVATE KEY---- is there. OK, it doesn’t seem to be the keys, but lets check to see if the keys that are there belong to me and my EVO. So again, back to XDA. This time I find a post that shows how to extract the RSA key and the device certificate and then run an MD5 sum to see if they belong together. It also shows how to look at the cert to make sure it belongs to your evo. Sure enough md5 checks out and the cert has my mac in it in the proper places. OK, lets check on the tree.xml file. Sure enough it has the right mac. OK, delete it like the instructions say. Now, I restart 4g, it creates a new xml file, but doesn’t connect. That’s ok, the guide says it likely wont. I update profile/prl, reboot, turn on 4g and no go again. Lets do the profile and prl again just for good measure, same result. Hmm, look there is another way to do the profile update. ##data#, data profile, menu->restore. The phone reboots and runs through all the provisioning steps. Still the same results. Once more, back to xda forums. This time I find a post about checking your wimax partitions with wimax_mtd. Well, wimax_mtd thinks its all good too.
By this time I am really confused and figure maybe I can unroot and apply the RUU to dump it back to default config. Now my phone is unrooted and STILL doesn’t have 4G access. After rooting the phone again and going back to another sense based rom I ran a tail on the sequansd.log file, again found by xda / google searches. Here is where I have no idea what is supposed to happen. Here is the tail of the log file. http://pastebin.com/f2jL4MVF and here is a catlog from another attempt. http://pastebin.com/sZ2BiM9g
Here is where it gets odd to me. I changed my realm to clearwire by using ##data#, wimax, realm, clearwire-wmx.net, reboot. Sure enough it connects and gets redirected to the clear.com site. I ran a tail of the sequansd.log file and get basically the exact same things as I got when I ran the tail while on the sprintpcs.com realm. http://pastebin.com/0EU7Qh86
This is where I am stuck right now. Thanks for reading this far and sorry for the novel. Hopefully I gave enough information that this can get resolved and maybe it will help others.

Call Sprint.

I have never had this problem last this long, but I have had problems connecting to 4g before. MikFroyo 4.2 and Myn rls4 both had connection issues but it was usually a simple reboot before it was fixed.
I honestly have no clue. If your Mac Addy is fine and your RSA keys are there, then this is seriously a conundrum.
I'd suggest dropping your phone off a 3 story building and getting a replacement. That's just me though.

I called Sprint and went through about 5 techs. They ended up saying they don't know what is going on and that they cant see any errors on the tower I am connecting to. They set up an appointment for me to go into a local store.

GPS quick fix from sprint.

I had posted this in someones thread just thought I would rephrase the topic. Just got of the phone with sprint after 2 hours of troubleshooting. They made be restart my phone a million times didn't work, they made me reactivate the phone didn't work, and finally got transfered to someone with a bit of knowledge and its been working so far.
what they did with me on the was:
1. go to settings
2. system updates
3. update profile
4. restart
It hasn't gone to **** yet hope this works for the long run not for now.
Once again this is temporary fix until they figure out whats going on with the phones.

Its a samsung phone, for some reason they have some of the weakest gps signal I've dealt with...

it's because it's a cdma samsung phone. every single cdma samsung phone i've ever used or owned has had absolute terrible gps signal and support. granted, this phone has the best gps signal of any cdma samsung phone i've used yet, it's still ****ty in comparison with HTC.
gsm samsung phone dont seem to be plagued with terrible gps support.

I agree, I just switched from a HTC EVO 3D and never had any problems. That sucks because it's a great phone.

HTC EVO and evo3d, moto photon never had GPS problems, my samsung moment and ET4g always have, cdma has nothing to do with it.

I think one of the biggest things Samsung really needs to improve upon is software development and programming. Compared to other smartphone manufacturers, they suck at it.

Thats amazin...Ive never had a problem with GPS thru Sprint on all my EVO phones and now the Galaxy...Ive had many a custom Roms on here and still never a problem...Locks in Seconds...Only problem was with the ICS builds ...but there was a fix for that ...So now still on a ICS build fb21...Locks in seconds...

evo 3d no problems at all. the moment i switched to e4gt i started have problems with it locking on with stock brand new phone. have a new one now and it started doing the same crap again i'm using the fb21 before the fb17/15 and the same thing. i have learn to just do the quck fix and live with it until theres a permanent fix for this problem.

I have my E4GT flashed onto Boost mobile. The GPS has NEVER worked. When I try to update my profiles, I get an Error saying "Error: Client Authentication Error"
So, I assume it's because I'm on Boost.
Anyone know of a way to update my stuff? Maybe get this GPS working?

Not to burst your bubble, but people that have GPS issues almost always try to update their profile and or restart the phone. That's kinda basic I would think. Typically the issues are with the radio like people pointed or the drivers if flashing different ROMs. THis used to be a huge issue on CM7 back on EVO I remember.

Even though you are on Boost, the software and qpst for the E4GT is still set for Sprint. You have only manually changed the important parts to connect to the network.
You cannot update Sprint profile and PRL through the phone for boost. The way to "update your profile" would be to reset the APN settings and re-provision the device.

Running fb21 with little issue with GPS, no stupid fixes, it just worked. Un like other updates....just saying.

wow back to the same crap again with the new e4gt this is frustrating i thought a new phone later it will work but still the same crap. does anyone know pf a better fix than this before i go hostile on sprint. they still try to tell me its the area i live in. i just lost my evo 3d thats why i got this phone and never had one problem at all.

Rarely connects to 4G/LTE even though signal is good.

I'm in UK with a unlocked HTC10 from carphone warehouse, on the ThreeUK network.
Recently I've noticed that I no longer connect to 4g other than a few very rare occasions.
The only changes,
1. full update to the latest OS
2. I removed the sim card and put it into an old phone, when I re-inserted it into the HTC I got "network updates" which I accepted.
Things I have done after verifying mobile network/data is set to AUTO
1. delete all APN
2. reset APN to details available on my carrier website
3. Settings >backup+reset>network settings reset.
The odd thing is very occasionally it does decide it likes LTE and it works fine.. but its rare.. even if I do a reboot or toggle airplane mode.... the second I remove the sim card and put it into my old phone I have LTE, so it really isn't a signal issue.
My network have suggested a factory reset, but I am not rooted and have game data among other things that are impossible to backup. so at this stage I would rather not .
totally flummoxed by this one!!! any help or suggestions appreciated...

Sent from my hTc 10

Thanks.
I got a bit of time today, so did a factory reset.. same error still.. and again I put the sim in my old phone and bang 4g straight away..
in the HTC if I leave it in a strong signal position for several minutes I can see 4g occasionally pop up, but if I walk away from the window it goes again, even though I get 4g through the whole house on my old phone, and did on the htc when I first got it.
Actually thinking theres a hardware fault now.. bit of a strange one.. but looks like i'll have to return the phone tomorrow. we can try a different sim first in the shop

Just an update.
I spoke several times to HTC, one ran through basic resets with me no change (hardly surprising as I've already done a hard reset). this agent "sent through" details for return item for fix.. but these took days to arrive so in the meanwhile thinking they were lost I phoned again.
This agent was going to send me a email with lots of settings changes to try... this email never arrived....
Now since then I've done a lot of research online, and found that there are quite a few sites saying the htc10 on the new software has LTE issues, poor signal dropping signal etc.. IE it is my error, so why did htc support not know this? I wonder if its generic media articles or actually a "known" fault... its so hard to search here as both 4G and LTE are too short search terms..
Now Do I bother to send it back to them and be without my phone for a couple weeks?? if its software then surely they cannot do anything... I wonder how long until the next OTA update that may fix this if I just wait it out??
Really don't know what to do, I rely on my phone a lot, 4G isn't really "needed", but I do find the 3g signal is quite poor around a lot of areas I used to get good 4G.

Bro im on 3uk but im on us unlocked firmware with working 4g lte and volte and wifi calling...
On stock 3 firmware i had appalling 4g connectivity but 4g has been crap on 3 for years. Try s off and update firmware to .617 and use a custom rom like viper

Thanks, I'm currently on 2.41.401.3
I have good 4g on my old phone (now sold), and this htc10 was better when I first got it, now its aweful,
Can you link me the exact software youre using? I'm very new to the HTC, I assumed the europ unlocked software would be the same as USA? but I don't get Volte or Wifi calling on 3uk..
I use mirrorlink quite a lot, and like the HTC software, so i'm keen to keep on a stock rom so I can use android pay as well etc.. or is your rom custom/rooted etc? Sorry to pester, you're the first threeuk customer on this phone I've come across. any extra details/information would be awesome thanks.

Search for SneakyGhost firmware htc 10 xda, exactly like that in google i am not sure if im allowed to send links on here that's why and you will find the firmware in their, its 2.xx.617.x
My phone is rooted, head over to the viper 10 page on here its a custom rom... If you get an RUU exe file you can install
617 firmware and stock rom and will have working volte, inside my home i have 4g lte connection so its about 60mb download speed, no joke on 3!!!! Lol with an RUU you will lose ALL data so back up on pc and move back over afterwards, any more questions or if i was clear PM me

So a bit of an update.. I chickened out of a software change... So got the sim changed, no difference, gotthe phone sent for repair, they updated to 401.4 but no change.. rang again, and we tried setting to 4G only using the service menu, and bop 4G signal just fine.. so it genuinely is a software bug in 7.0, the stupid thing is I had one bar at 3G, I swapped to 4g only and had 5bars!!!!! so it wasn't even like it was favouring the strongest signal.. just a shame I cannot receive phonecalls on 4g, so I need to leave it set to auto and just accept until they sort it that I rarely get 4g.. but at least I now know if I need 4g at any point I can go to the service menu and swap to 4g temporarily. he sounded like there have now been like a few reports of this, so hopefully HTC take it on board and push a software update promptly. he suggested 3-4weeks as a potential timescale, I suspect he meant months.. but fingers crossed

When you were having this problem was Chrome allowing you to access some sites, but on others saying that the DNS server could not be reached? If its same problem that you are having I can't use your work around as it's difficult to get a 4G signal where I live.

Sounds like you're having a different issue, assuming you have a data connection, and each website has no server issues, or the ISP isn't blocking the site(usually they'd say not a DNS error) then one site should load as easy as another, I have these exact same issues when I have ad-blockers enabled on certain sites (some you'd expect to work).. do you run a blocker of any form? try disabling it and trying again on that website..

I tried a variation of your solution and made the phone only connect to 3G or lower which seems to have solved the issue even when I switch back to 4G, hopefully it's not just a coincidence. Thanks for your advice.

Three UK user here, just tried the service menu 4G force and that seems to work for me, I shall see how it goes. Good for dead spot testing
So a few days later: Leaving it on means 4G pretty much everywhere I go but the obvious downside is no calls even through the ThreeInTouch app. Bit of a downer so back to watching it sit on 4G until I want to actually use it then it goes 'Hey let me check jump back to regular H for you'
