I was wondering if anyone else has this issue. I think most people know by now the issue we all ran into with 4G after we flashed roms with the new OTA update. The 4G would just be stuck at "scanning...." and never connect.
Anyways, I did manage to fix the 4G issue using bigbiff's steps here. So now the 4G connects with no issues but there's one problem: when I leave 4G area or go indoors and come back into 4G area it won't reconnect by itself. I have to either turn on and off 4G or hit the "Scan" button.
If anyone can give me any insight or ideas as to what's going on that would be very awesome.
I have the same problem, and I have seen at least one other person mention this problem (it's kind of hard to search the forum for this problem, since all you get are the folks having problems connecting to 4G).
This started after the OTA update. If the 4G signal fades out, the 4G status remains in "scanning" even in known 4G areas. I made one 4G change to try and fix this - I changed the wimax_idle_sleep time from 10 to 300 as was recommended in the 4G problem posts.
I am wondering if anyone knows what the other 4G settings do and if any of them would fix the problem. So far the only way I know to reconnect to 4G is to turn the radio off and on.
I posted this in another forum, the more frequented one. I thought it was more applicable there since this might be an issue concerning rooting, custom ROMs, home ROM flashing, or all the above. Until I see a wave of non-rooted users complaining about this, I think Sprint has found a gotcha for rooters and flashers. Input from some ROM developers would be nice if they happen to visit this forum.
I can enter a 4g area, turn on 4g, and connect. When I leave a 4g area, turn off 4g, then turn 4g back on before re-entering 4g area and enter a 4g area, it is stuck scanning. It never attaches to the 4g network in the area I entered. If I turn 4g off and on while in 4g area, it will connect.
Are unrooted stock users having these problems? It is a real let down and PITA. Is 4g working perfectly in all scenarios for any rooted user?

I also think it's related to one of the images we have to flash to get root, as the behavior is definitely different than stock. I noticed this after I first rooted / nand unlocked my phone, but before I applied the new radio & wimax. On my phone, however, 4G does eventually come back up. It might take 5 minutes or more, but it does eventually reconnect.
I'm not sure that it's really a bug though. I actually prefer this behavior because it results in fewer dropped connections when switching between 3G and 4G. For streaming apps (Rhapsody, Pandora, Youtube, etc) the frequent switching forces you to have to start the stream over. I think it might have been an attempt to increase the stability of the data connection at the expense of having a 4G connection less of the time. Could be a hold over from one of the older engineering builds we had to flash during the rooting process? It's strange that the behavior persists after flashing a new radio/wimax, but maybe it's actually controlled elsewhere.
Add me to the list. This is from my post about 20 hours ago which hasn't received any bites:
I have seen various issues reported:
1) 4g won't turn on. PERIOD.
2) 4g turns on but only scans - never connects.
3) 3g/4g alternate so there is never a stable connection.
4) 4g turns on and connects but after a while disconnects and won't reconnect until it is toggled on/off with the widget or check box in settings.
I used to have #3 until I did whitslack's "start over" method and now I have #4. I've changed my wimax idle sleep time to 300 in ##data# and verified a good MAC so other than the 2 evo last resort method I think I've tried everything other than the above.
So, does anyone know if renaming/moving macaddress.tree.xml is for my issue #4? Or does anyone know a specific fix for #4?
If it matters I rooted with toast 1/2 and am still on the rooted stock ROM from whitslack's "start over" method.

Some Observations:
I've noticed the following differences since the OTA (with Root-from the "How to Start over with 1.47.651.1" thread):
1. The 4G reconnection problem.
2. Bluetooth no longer auto connects when my headset is in range.
3. I have been getting "Error 67 Data Connection Lost" errors. This error blocks me from 3G data connectivity for a few minutes. During this time, "Mobile Networks" shows "Turning On" in the settings.
I suspect it is one of the following:
a. There is still a radio problem with the rooted OTA
b. the PRI that has not been updated since the root crack matters with this release.
c. Sprint/HTC introduced some new bugs.
d. Some hardware settings need to be tweaked (like the timeout that folks are changing from 10 to 300).
So we need to figure out who is having this problem, and under what circumstances.
I did however note something very interesting. I have repeated this 4 times today. If the 4G disconnects and stays in scanning, if you then place a call it will immediately reconnect. This leads me to believe that it is indeed a setting, and a voice call triggers it (if you recall in May, Sprint was saying that they hope to have Simultaneous Voice and 4G - so there is probably some code to trigger 4G at this point).
What do you folks think.

I would take C out because I have not read complaints by non-rooted users.
The latest PRI is 1.40_003. Right?
Who can bring this over? ROM developers say those features are not part of what they do. If not them, then who?

I think being rooted currently sucks. One of EVO's greatest strengths, connectivity, has been crippled.
sw99, did you try the move the xml file with your mac address solution? If so, I guess it didn't make any difference.

I will try making a call tomorrow when this happens and report back.
I had the same problem pre-root.
I wont be able to help anybody too much with technical stuff 'cause I'm basically a non-technical guy, but I've had the same problem with wimax dropping & not reconnecting ever since the OTA update (1.47....). I went to a Sprint store & the guy just went cross eyed, so it may not be too common.
In my case the connection will SOMETIMES come back on its own with a really strong signal, but rarely.
I just rooted tonight so I have no idea if it's worse or not, but I'll find out tomorrow, eh?
I've also had difficulty with Bluetooth automatically connecting, but I have a new stereo so I don't know where the issue lies.

Nope. Didn't touch the xml file, as my 4G was connecting, and the fix was for 4G just scanning.
I still think we can tweak the WIMAX settings and make it come back faster.

This is basically the only thing I haven't tried.
I tried making a call to reconnect to 4g three times this morning. IT WORKED ALL THREE TIMES! Odd....

Well at least its faster than toggling the 4G radio - just find a friend with a mobile phone so you don't waste any minutes.

Just dial your own number which takes you to voice mail and shouldn't waste minutes. I'll probably put a direct dial shortcut on my home screen until a solution comes along. Not that I'm worried about wasting my regular minutes....I used 29 of 450 on my last bill!
I can now confirm that moving/deleting the xml file does nothing for our problem. At least not on my EVO.
So, I've been looking at the WIMAX settings (using ##DATA# and my MSL).
There are some settings that look like they could be effecting this problem. Be forewarned, however, that some of the values preset are not considered "valid" when you make a change (leading me to add credence to my theory that HTC/Sprint goofed), so I'm hoping a nandroid backup will recover them. Open each parameter and deleting the values, gives you a popup of the valid values and units.
Here is what I tried so far:
wimax_idle_sleep(s) changed from 10 to 300 seconds - effect: little to none.
wimax_scan_attempt_timeout(s) changed from 1 to 20 seconds - effect: little to none. (note only 5-300 are valid values after this change).
Other parameters that look interesting and their default values:
Wimax_scan_retry(s): 300 Seconds
Wimax_entry_delays(s): 300 seconds
wimax_exit_delay(s): 2 seconds
idle_mode_timer: 60 seconds
Standby Time: 10 Minutes
handoff Threshold: 6
Anyone willing to mess with these (at the risk of losing Wimax, of course)?
That is one place I'm not going to mess around. I saw a stern warning about that recently on the dev forum.

I still have my doubts about that. I put a link in the General forum to this thread, and we have one response. I read around the non-tech sites with 4G forums like SprintUsers, and I don't see these complaints.
I would like to hear from a tech oriented non-rooted user.

I did see a couple of non-root complaints, but I can't find them now (not on your standard sites).
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.
Hello,
I've searched around the Epic 4G Touch forums as best I could, but sadly I couldn't find anything that was exactly this problem (although I found some interesting articles about wifi sleep time but they don't seem to apply). I'm experiencing an annoying issue where I can connect Wifi just fine, but if the phone is left for a small period of time (~10 minutes), wifi appears as if it's still connected, however it cannot send/receive data. When this happens, the wifi status says it's "connected", but there is no data connection. The only way to to get the data back is to turn off wifi, wait for 3/4G connection to initialize, then turn Wifi back on to refresh it...then it's fine again until I set the phone down again.
I had this problem on stock EL29, so I rooted and flashed Phantom Blazer ROM (very cool ROM, but I'm still experiencing the same issue). After reading the threads on here about wifi sleep times (apparently they're backwards with ICS roms), I've experimented with every setting, yet I still have the same issue--Wifi is fine as long as I'm using the phone, I set it down, after about 10 minutes pick it back up, says it's still connected, but no data connection.
has anybody experienced this problem with this phone? I'm about to unroot my phone/go back to factory so I can take it in to a Sprint store, the problem is they (trying not to be offensive) don't seem to know very much about this device. I thought I'd ask the pros before I return it, get an iPhone, and have to eat my words about how cool Android is vs. iPhone in front of all my friends. I'm hoping there's a reliable ROM or app that can resolve this vs. having to just replace the device!
Thanks for your help!
I'm not the only one
I'm not the only one with this problem:
edit: I can't post links to androidforums.com or anywhere else, but this same problem is all over the interwebs and nobody has a solution.
I'm sure it's not my router as my ASUS tablet/laptops/girlfriend's iPhone experiences no connectivity problems. I'm thinking this is a hardware problem with some of these devices. I will unroot/reset to factory tonight and let you know what happens.
What channel is your router on? And what type is it A/B/G/N?
This is s known TW ICS bug, most likely kernel related. Almost everyone is having this issue and there is no fix until Samsung decides to repair it. There are quite a few posts similar to this one. If you're using XDA's search function, it's not very good. Try using Google next time and search XDA that way.

Hey guys, thanks for the response. Just before I unrooted/reset to factory I tried one last solution--download an app called "Wifi Fixer". It has resolved a lot of these problems. It's not 100%, but after testing it for a day so far, I've only had to manually refresh the connection once or twice. It's a lot better, even liveable, and I won't be resetting to factory afterall, at least not until Samsung provides an update. So if anyone is having the same problem, try Wifi Fixer, hopefully it gives you a similar level of success...I'm not super happy about having to run another background process all the time, but it doesn't seem to affect battery, and the fix it provides is worth it to me.
Cheers!
Huh - a couple of things. Noticed this problem crept back in FF18 and didn't know why until I went back and checked the wpa_supplicant.conf that I'm using. The line ap_scan=2 was missing; after adding it back in the signal strength is back to full and stable.
I'll bump the thread but it appears the config changes here still hold after all:
http://forum.xda-developers.com/showthread.php?t=1569348
This should also avoid having the WiFi fixer there as you can specify the country in wpa_supplicant.conf manually.
Thanks for looking in to this! A couple questions from a noob like me though:
When you say the problem crept back in FF18 ... what does that mean? Is that something that exists in the "stock" version of the Epic 4G touch from Sprint?
The manual config file tweaks you're describing ... is that something I can perform myself?
Basically I'm wondering if it's "safe" to revert to stock in order to get consistent wifi signal, or if it's something I'm experiencing because of the ROM I'm using.
Thanks!
Hey guys, new here to the forum. I've been using the forum a bit lately and have updated a load of things, including CM10.1, hboot 1.07, incredikernel latest jb 4.2, baseband, etc. I noticed people saying you can change your protocol from EVRC to EVRC-B. I tried following the various methods like ##778, ##program, so on and nothing seems to work. Is there a different code I'm supposed to use? Is this even a possibility with the ROM/Kernel setup that I have? It's the last thing that I wanted to do and it's bugging me.

I think there is. Google search EPST AOSP and there may be an answer for you there.

I dont think there is. Every thread i find says there isnt, and to just backup your current setup, flash a stock sense rom, change the settings, and then restore your backup. The settings persist thru rom flashes. There is a pc program QPST, but im not sure if it would work or not without the epst.apk being present on the phone.
Its true you can change from evrc to evrc-b, which i have done before. However in my opinion it makes call quality no better, and can make you roam or loose connection if you go to an are that dosent support evrc-b.
Yeah, I searched what tiny suggested and that was the only solution really. Not really a problem I just thought I could streamline it. Isn't the EVRC-B a preferred setting not a forced setting? That what I thought people were setting it as for those 3 locations "home" "roaming" and whatever the third was. Maybe it just states preferred but it's really forced causing you to roam more often. I think I'll give it a try and see how it goes for me.
Look i normally dont ask for to much help ive been around a bit know more then the average bear. I also fix hardware.
My problem is my data radio will not switch on from any attempt:
Attempted solutions:
Dialed
*#*#4636#*#*
Will not switch on from that screen
Did the obvious and switched on and off airplane mode
Replaced the entire build.prop file with a very stock build.prop after flashing stock jelly bean
Repeated steps for all stock firmware
Newest attempt wiped the entire system partition through recovery forcefully bricking the phone. I have now flashed the original stock e980 stock 10p tot file still no luck
My phone is completely unlocked fully rooted.
I've replaced the data permission files.
And I know its not the SIM card because the SIM card is in the phone I'm using right now which is an LG g2 unlocked which is for sale by the way.
And if it is a hardware problem I have not found any related video or thread to help me find an exchange where the radio is on this thing
Help me please if anybody has any idea?
Cool no help, hey moderator can u move this to thread that may get more help that would be awesome
i came looking around here because my g pros radio stopped working sometime last night while i was asleep and was about to make a thread asking for help, but seeing as how you haven't got much i doubt i would either. but ill give you a little info on mine, will it help you out at all? not sure. but i know it might make me feel a little better.
I flashed Vanir 4.4.4 last week coming from Beanstalk 4.4.4 cause beanstalk was getting buggy from all the ugly mods i subjected it to. so all was well with Vanir till i woke up this morning and had no service, no calls, no network, AND even if i connected to a wifi network it seemed that i couldn't get any data from it. I tried flashing madmacks modem cause who knows, maybe thatll help, but it diddnt. So then i flashed a different kernel and changed TCP protocols cause who ****ing knows, but it did nothing. THEN i restored my older Beanstalk 4.4.4 backup sure that it would work flawlessly but guess what, same problem. Now that im back on Beanstalk i went to the "Network Operators" option under "Mobile network settings" and selected ATT, which is my service provider, i can now make calls and texts but still no data, when i did this on Vanir it did not help. So i started messing with my "preferred network type" and realized i have data on 2G, but not 3G or LTE. Im gonna take a wild guess and say that maybe if you flash your phone back to 100% stock your radio should start working again, as much as i dont want to, i might end up doing that as well.
tl:dr
similar problem, i dont really know ****, easiest option = go back to stock, hope it works.
@Fant0m3 @alb-o
Have you guys checked if your rom shows your imei?
I have had this problem twice. My IMEI disappeared and I don't know how.
Your symptoms match.
If that's the case you could take it to a repair shop and they'll fix it in a minute or two. Or, you can check around xda.
thats a good point, when i was looking around XDA earlier i saw a few mentions of it but diddnt see anything very specific and was late for class so diddnt have time to look for too long. strangely enough mine actually started working normally again after i kept switching from 2G to 3G to LTE, which is great. but if i would've known that info earlier i could have checked if my IMEI disappeared while my radio still wasn't working, i assume it probably did.
after searching around more i found this thread that talks about it and how to prevent it:
http://forum.xda-developers.com/showthread.php?t=1857054
thanks for the help g0at1, hopefully this helps out the OP if he hasn't already fixed the problem, or anyone else that comes across this.
nope
I've flashed back stock numerous times even flashed other versions such as e988 and back again if u dint know how to do that just change your build number in your build prop file...I've tried everything I am downt to antenna cable SIM reader or cell radio.. If radio I might as well just give up cause I can't find one for sell anywhere...I'm not so pressed as I'm using the LG g2 and it's so fast stable and a bit slimmer I think I'm gonna keep it but I would like to fix it and sell it though...... My symptoms are mentioned and all tried fixes are there. Imei is read carrier is not WiFi is received but there is an X above the data bars phone is fully unlocked as well
This may help also but it does not read my imei when the SIM is not in hmm maybe I will rework the imei code and get back if that works. I will keep updated when fixed and with solution
