4G reconnecting issue?

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.

TP2 - No Network when 3G Enabled :(

Hi Guys,
not sure what do do, ive tried updating Rom (currently running latest Energy Rom) although had this problem before updating to the latest, previous was a few months old.
Also updated/changed the Radio version - still nothing.
basicaly - whenever i enable 3G - my phone drops the network connection, whereas for the last 18months not had a single problem - nothing has changed as far as im aware..
Anyone had this or got any suggestions on what to do ?
VODAFONE.
my problem happens all the timel; ie i cant get a 3G connection, when i select to enabke 3G it just drops network totaly, cant make calls, text etc etc.

I actually just starting to have the same problem... Are you on Vodafone in the UK? My problems started yesterday evening...

I've been hearing a lot about this lately. I think it has something to do with Vodafone and Orange combining network coverage. Try the following to see if it works. Make sure to back up your stuff first.
task29
Flash Stock ROM/Radio (they should come bundled together)
task29
flash custom ROM
boot and then hard reset.
See if this fixes the problem.

Yeah Vodafone UK! - My problems started Saturday Evening, between Sat Evening and Sunday afternoon (after i'd flashed and changed the 3G setting) - i then got a signal...
Ive tried enabling the 3G Since, and it just drops out!
Might try FLashing the Stock Rom - any idea where i can get a standard rom/radio ?

Did all that, used the _HTC Touch Pro2_RUU_Rhodium_S2_HTC_Europe_2.07.401.1_Radio_Rhodium_4.49.25.91" ROM from HTC site, then reflashed with "Energy.RHODIUM.21916.Sense2.5.Cookie.2.0.Nov.19" but I still have the same issue
Vodafone and Orange? I through it was Orange and T-mobile that were merging? Every time I turn my phone back on or come out of flight mode my clock move forward 1 or 2 hours... If I don't change the time, the coverage work but if I set it back to the normal time, the coverage stick only on GMS mode... weird and weirder...

Stock ROMs come with the stock radios. No need to flash a radio separately.

I haven't heard anything about T-Mobile. Vodafone and Orange aren't merging. They're sharing use of their cell network. Meaning customers of both companies are going to get increased coverage throughout the country. I've been seeing lots of posts about how this is affecting users negatively on the networks, though.

another day and my data connection doesn't even turn on anymore... No more disconnect from the network tough, just greyed out E connection...

You are correct. I had it backward. It was T-Mobile that teamed up. I didn't check the link I gave as it normally has each ROM for each carrier, so I generally just link it by default. The 1.8.6.161.1 is the latest ROM from Vodafone. You don't need to keep it on the device, you just need to have it return everything to stock conditions and move on from there. It's like working on a fresh, clean slate.
Man, I'm off my game today...

Data connectivity issues

Anyone else having connectivity issues with their one x? If the phone loses connection for any length of time, it will not reconnect and I'll have to reboot the phone for the mobile network to reconnect, which is probably every 15 minutes or so.
I skimmed a couple pages, couldn't find anything, but I've found a couple other forums with people posting about this issue. it's an ATT one x.
Hoping there's a fix for this as every ATT store within 50 miles is out of stock on both colors and customer care won't do a damn thing for me but tell me "go back to the store." Bull**** if you ask me, broken ass phone and I'm stuck with it. Really?
I was hoping there was a fix, even if I have to unlock the bootloader and root.

Of all the issues that people have been complaining about since the phone was released that's not one that I've heard mentioned.
However, it's probably worth you asking the question over in the AT&T One X section, as this is section is for discussion about the international (Tegra 3) version and your problem might be something specific to the One XL hardware.

im having exactly the same issue. works fine when staying constantly in coverage but when i lose the connection going through the subway tunnels it doesnt reconnect. searching all networks fails even! its like the radio switches off.
i got it to turn back on by turning it into plane mode (which took ages and look like it had frozen but eventually ticked over after about 30 seconds). once i turned plane mode off it asked me for my sim pin again, then after that it reconnected normally.
which made me think... that shouldnt happen and has never happened on any of my other phones. so tomorrow morning im going to try going through the tunnel after turning my sim pin off and see if that fixes the problem. maybe when the radio disconnects it tries to reauth to the sim but but the UI doesnt prompt for a pin and it stays off... worth a shot because i havent seen anything else that seems to apply to the international version, only the LTE version and needing to select GSM/WCDMA instead of LTE (which this phone is defaulted on already).
then again this would only make sense if the poster has a sim pin on as well do you?

I'm having data issues with 3g and WiFi. Most of the time is fast and reliable, other times is just does not connect.
Stock HT24 international one x.
It's my only issue with the phone but store has said I can return when ht25 stock is in if I like.
Sent from my HTC One X using XDA

I did not realize there was a forum for the ATT version of the One x. Sorry for the mispost, but no, airplane mode does not fix the issue, it needs a hard reboot. What I do for the meantime is turn data connection off when im not using it, then turn it back on when I need it. Annoying to say the least, but.... whatever.

I also have connection issues on the mobil network. Very often it drops out, and wont reconnect untill im very close to an antenna. Its a big problem, as it can't connect from my home +/- 100m, and i live right in the center. I don't have this problem with other phones, so i think its a HTC One X problem, even thou the phone company has a weak signal in my area.

I can confirm that upgrading to 1.29.401.11 fixed this issue for me.
I did try unlocking the SIM card but that didnt do anything. Flight mode did work for me but that was just annoying and I missed a few calls and SMSs being in elevators and not realising it had dropped as well.
But anyway, I read that the .11 firmware had a radio update so perhaps that fixed it. If you dont have the Intl English version like me (i.e. 401) you will need to wait until your localised version is updated.

Three Uk Signal Dropouts

I no that i am not the only person who has this issue and it is driving me up the wall. for some reason when i loose signal alltogether it wont auto recontect when i come into signal again instead i have to force it to reconect.
At first i put up with this becasue i loved the phone and i thought that three would be doing somthing about it to fix the problem. but as i have recieved no fix i am getting more and more tiered with the phone and im swaying more and more towards the S3.
The only way that i can hold a signal is if i set it so that i am on 3g only which helps but suks becasue there are alot of ares which dont have the 3g signal.
i have also noticed that the phone looses signal when i put it in my pocket so if somone is trying to contact me while i am not actually using my phone its like i might aswell not even own it.
This signal issue is pretty much rendering my phone usless does anyone know of any fixes that i can posibly do i have not applyed any OTAs directly from three but i have unlocked my phne with HTC DEV and have installed the latest stock roms to try and sort it out with the latest euopean radio to no provail.
does anyone have any sugestions for me? a posible fix? news from three or should i just give up on the HOX and switch phones altogether.

Same issue here dude, minus losing signal in my pocket. Also, I have to use the airplane mode and not toggle the network connection to get it to work

You can make the setting permanent by instead going to "Mobile Network" in Settings, then "Network Mode" and select WCDMA Only. That sticks across reboots.

it has been 2 months though and it still hasnt been fixed HTC are taking the piss with this

Also another thing I have noticed is the signal is slightly worse in a case than without.... So mine at work can be hit and miss even more. I am on Three to with the Three firmware.
It has actually been better since I got it back from HTC repair. They seemed to have changed the whole housing and battery in the report for the squeaking and moving lcd screen. Maybe they have done a better job at putting it together than from Taiwan?

Although I didnt have this exact problem with my HOX from Three…. (just had crap signal, would re-connect OK though, but was hard to get from 3g to 2g and back again sometimes) mine just had poor signal everywhere…. so much so, I cancelled the contract. Cost me £500 to get out of it…. but well worth it TBH.
S

I purchased my one x from amazon and got three to swap my sim from my desire to a micro sim. I only get loose network when im at home.
I reported the network drop to them and they got back in touch. They said that there was not a problem with my phone its just the location of my house and the distance away from the mast. After someone from the network team called me they said that we can offer you a "home hub" (for free) which connects to my home router which provides signal in my house. There is always a catch with companies. They wanted me to renew my contract as i have 2 month left. I am not going to renew as i can find cheaper sim only deals.
I guess what im trying to say is that if you have a long contract left with three file a fault online and push for the home hub.
There is no harm in asking.

I have the same problem with Three and at first I was just like ahh I can live with that.
Now its really starting to annoy me no signal indoors what so ever and when I leave the house will not auto connect I have to enter and exit airplane mode for it to pick up a signal again, Ive sent in a complaint will see if they get back to me.

Mobile signal problem

Hello guys, my phone fails to connect to the Internet under a specific circumstance even though it receives 5-bar HSPA signal. This problem is a bit tricky to reproduce. First, I'd like to say that it's a 4G plan and my phone IS ABLE to receive 4G signal and has connection to the Internet wheb no problem occurs. When I go to some places that my phone receives 2-bar signal only (e.g. in Elevator, tunnel, etc.), it'll drop to HSPA with 2 or 3-bar signal. It seems normal, right? But then I go to somewhere that's supposed to have 5-bar signal or even has a clear blue sky above, my phone receives 5-bar HSPA signal with NO connection at all! Here I say No connection instead of no Internet connection is that it can't even receive or make any call when the problem occurs. The phone will obtain 4G signal again only after turning off and on mobile network or Airplane mode. Otherwise, it just sticks to this status forever. Or if I wait for an enough time, which varies from a few minutes to half an hour, it'll eventually have an X on the signal bar and reset the connection to work again. This problem's already driven me crazy! May someone help me please:crying:
I have an S-off unlocked HTC_622 HK version device (was changed to superCID recently). It went through every version of firmware from 1.80.708.X to 2.28.401.9 and both HK stock ROM and LeeDroid ROM.
Edit: It also happens sometimes when it connects to 4G.

I have used an unlocked HTC 10 with T-Mobile service and haven't had this issue, but I had similar issue when on WiFi.

I also noticed there is no Internet connection when it's on LTE band 8

Did you drop it ..?

No, never dropped it. It's been like this for a long time. I thought that was because of faulty SIM card at first, but it turns out the SIM card has nothing to do with the problem.

Send it to service then. It may could be a hardware issue

if you reset everything back to original does it still have the same issues? If so then probably a rma request is needed

I consider doing it all the time since it's happened. Last time I called for a RMA because of touchscreen unresponsiveness along with signal issue. They just replaced the screen and did nothing with this issue. What concerns me most is the phone looks and behaves like 120% "normal" as long as it doesn't undergo the "specific circumstance" I mentioned. Looks like I need to state very very clearly about the problem this time.

At some point, I'd been using stock HK ROM and kernel for a week or two with root only. It still had the same issue.

Hi
I have quite the same issue as you with my phone except it is with 4G. I explain, some time I can have a full 4G strengh (4 bar signal) and still cannot access internet, or send SMS. It seems that my phone can send data but not receive because I'm able to make a call, but not receive one. Also people receive several time my SMS : they still appears as sending in my app and I believe their are sent but my phone seems it doesn't receive any confirmation, so it still try to send it.
If I go back to 2G/3G mode in network, everything works fine. This would be easy if 4G never works, but sometime it does so this looks like a random behavior.
I think this is a 4G band issue. I found an app called LTE Discovery that display information about your network. My phone works correctly when I'm connected to band 3 and 20 (can see the exact frequency in the app). My carrier (SFR, in France) uses also band 7 and 28, but I still need to confirm those bands work or not (seems band 7 works but not sure, this might be specific frequencies of this band that fail).
And when my phone does not work, the app fail to display the exact frequency I'm using.
I have an unlocked boot loader, Venom rom 4.2 (Android 7) and an old firmware (1.80.xxx). Issue started to shwo when I was using Marshmallow, and a full wipe and rom reinstallation didn't fix it.
Does it looks like your issue?

It really looks like for the part of 4G connection. AFAIK LTE doesn't handle phone call and SMS? Have you tried to test with other SIM cards and phones?
I also use LTE Discovery to test my phone. My carrier uses LTE band 3, 7, 8. My phone does receive signal of all these bands and works fine with band 3, 7 even with 1-bar signal. But for band 8, nothing about Internet works normally except for phone calling.
Seems my last resort will be switching my phone with my friend's (also HTC 10) to test with this problem.

Hi,
It seems I managed to solve my issue. For the moment I have working LTE at home, will try at works tommorow.
I simply update my firmware to 1.95.401 (was on 1.80.xxx) and it seems to works so far.
Maybe reflashing your firmware (if it is possible) could correct the issue?

I think you'll be "pleased" to know you're not alone:
I have the exact same issue, SFR , HTC 10, Venon rom 4.2.
I had a couple of exchanges with carrier support, always the same answer: our antenna is under repair...
The only way out on my side is to stay in 3G most of the time and then I can receive SMS, otherwise, no 4g in specific places, and very late SMS reception (I can receive SMS from 2 days prior... This happen when on 4g).
By the way, SFR made me get a 10€ discount every month when I told them I would leave, you can ask for it too.

I've been on 2.28.401.xxx since a couple of weeks, I've got the issue, so maybe it's more related to a clean install?
I'll switch to 2.38.617.xxx and see where it goes

Does it appears your phone have a good connectivity when you are in 4G? I mean, my phone used to display all network bar and LTE logo but nothing seems to works.
Also, you can keep in mind that is the 4G only fail in some area, this is probably a software issue, not hardware. I also saw there was antenna repair in my area, but I was the only one to get issue. Can you compare with your mates if they also have network issue (same carrier, try to switch SIM) ?
What is your CID? Mine is HTC_034 and I couldn't install 2.xx firmware.
For me, the issue just happened, with no explaination. I didn't update firmware or install any new ROM. So yes install the new one might correct the issue for you too, if the symptoms are the same.

COnnectivity was at the max, and no traffic at all, no up or download, and no ping. That's what puzzled me.

That's something I've planned to do. A bit complicated thought, I listen to music when I commute and these loss of 4g connectivity happens in places I would not stop normally...
That's one of the places I've identified, maybe you'd know this place (I doubt but how knows...)

My CID is HTC__001 wwe, I didn't buy it from SFR, I don't remember if I tricked the CID or not. (well think so)

Not sure of this, I checked using the network monitor in the notification bar. Up arrow were appearing but not down arrow so I assume my phone could upload but not download.
Didn't check out you place specifically, but this 2 ones for sure did not works :

Didn't buy it from SFR either, but changing CID require to be S-OFF so I assume you have the orginal one. Don't understand why there is several CID with different firmware update, for WW/US version I can but for 2 phone both buy in France, not from the carrier...
Anyway, I thought this could be linked to a specific CID and matching firmware but it doesn't obviously.

I'll try the Brancion spot later today.
Something else I was thinking about, I wonder if baseband got updated , by now I have [email protected]_41.13_F.
Something I always asked myself in fact, does Radio gets updates in Viper or any other Rom do, and if no, how to.
I guess via RUU, but for now, I can't make it to work, I have to sort out how I did before

If I'm correct radio is contained in the firmware image, and will be updated with it.
You also can flash radio if you are S-OFF.
ROM won't update neither firmware or radio.
FYI I have [email protected]_59.06_F, which seems to be more recent than yours, this may be the source of the issue (no idea what version I had previously).
I used this tools to update firmware, as I am S-ON :

Thanks for the link, really cool tool!
I now have the radio latest version, I'll do the "Brancion" test tonight and report.

I've did the tests with the new radio, the phone now switches to HSDPA or 3g depending on network condition, so it sort of fixed the issue of being stuck in 4g without actual data transfert ability
