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...

I did, but except from the shock of saying such a poor interface the problem were the same... I got the "HTC Touch Pro2_RUU_Rhodium_S2_HTC_Europe_2.07.401.1_Radio_Rhodium_4.49.25.91" ROM from http://www.htc.com/uk/SupportDownload.aspx?p_id=250&cat=2&dl_id=913 my own S/N didn't work so I got "ht95tll00196" from the web. Didn't make it any better though...

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.

definitely Orange and Tmobile sharing coverage in the UK, I haven't heard about Vodafone:

your link didn't have the Vodafone stock ROM, on the HTC website it would be http://www.htc.com/uk/SupportDownload.aspx?p_id=250&cat=2&dl_id=797 but it's the 1.86.161.1, seriously old...
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...

Problems with WIFI, GPS and radio after 2.17 update

A few problems with 2.17 / 4.0.4
After i installed the update 2.17 i notice that my wifi is even worse. I have i good connection with my Dynalink D635 router. So i don't think it is a hardware problem. But wifi works just sometimes. It was the same with 1.29, but al lot beter Now i loses his connection and than it come back, but mostly there is no data-stream at all.
Also the GPS is not working fine anymore. Lost connection a the time. It was working fine with 1.29 .....
The radio (connection with G/3G/H) is also worse. And sometimes he lose my sim-card and even goes into flight-mode??
HTC, i dont know what you are doing over there, but i have to say that this product is absolutly not what i suspected. I waited for the 2.17 to give the product a second chance, but it is even worse

Basic question. Still, have you backed up and tried Factory restore?

recently my phone doesn't read the SIM after a few hours of use. Says there's no SIM.

agree with the first comment. Can't confirm yet WIFI performance but GPS is now really bad. It was working great on 4.0.3 same as WiFi

I used only files from the instalation guide. No other modifications

CUSTOM ROMMERS
Just ensure you have installed the rom correctly, aswell as flashing the right boot.img for 2.17.401.2, then although it seems like a pointless task, please do well to include the command 'fastboot erase cache' before AND after the flash of the boot.img, just to be sure we don't have any kernel bits left behind. You could also go the extra mile and clear the dalvik cache in your custom recovery...
STOCK ROMMERS
You should ensure that your update was successful (check this in settings > about > software information) If the software version is 2.17.XXX.X
Then the update was successful, just double check your radio/baseband is what its supposed to be which is 2.1204.135.20 (i think)

I have a good question: Did you drop the phone recently or otherwise do anything to push the phone case down? It sounds like you crushed all the antenna contacts or your case just isn't seated right.
SIM losing contact would suggest that the SIM pins aren't fitted snugly against the SIM. You can either put tape on the sim to get to to fit more snugly or send it in for warranty repair.

I did not drop the phone, or did something strange with it. The only thing i want from a device that costs € 500,00 is that everything is does work.

I've have experienced a drop in mobile network signal after the 2.17 update. Haven't tested GPS but WiFi seems alright. I have not dropped the phone nor done anything unusual to it, just updated. Before, I had 5 bars/full signal all the time, and when I checked battery stats the network signal indicator throughout the day was green. Now, after the update the indicator is yellow and I have around 1-3 bars if signal.
Also, I'm in Denmark so I got the 1.29.xxx.12 update which was supposed to optimize signal strength. So right now I hope they are working on a similar fix.

The Custom ROMMERS part worked for me.
I had the same Problem. Just checked after a half hour and it still works.
Just try this method

Dear all,
I was using the Lee-droid rom. I switched to insert coin rom 9.xx and even tried the android revolution rom. In both I had the same problem. Using wifi I have almost no data although the signal is strong. It just keeps trying to synchronize like for hours. But for some reason whatsapp conncection works and no problems there, but when it comes to loading the play store it takes ages (5 min. plus). I already searched the internet for solutions but haven't found one. When I use my providers internet, it also just keeps trying to synch (and for some reason never seems to complete??) internet is also really slow and it used to be faster on mobile as wel as wifi. Is anyone else experiencing this?
I am really desperate to get this working, I hope someone can point me in the right direction.
Edit: Confirmed that wifi does drop out sometimes and cant seems to get a signal although im standing right next to the router. But when I have wifi, I have a great connection, but almost no data, only whatsapp seems to work.

I can also confirm taht after the 2.17xxx update wifi is droping a lot. Didn't had that problem on 1.29. Also there are other issues but it will probably be best if I open a new thread or someone else does that, just for the sake that htc will read it and make our phones better

To me, your issues sound like radio related issued, although I could be wrong. You both on custom roms? With custom recoveries? I suggest if 1.29 worked better signal wise that you flash that radio in your custom recovery. That might improve your signal. Its basically different for everyone which radios work the best so basically it's trial and error.
Lemme know how you get on :thumbup:

I'm not sure if it's the same problem but i've been having a strange issue for a while. I believe is started when I began using jellybean roms (Not 100% sure). My phone will work for a day or two with no issues and then I just suddenly lose my gsm/3g connection. Numerous restarts later and if still doesn't work. Can't use it as a phone at all. If I reflash or change the rom, my connection works again for a few days and then then same thing happens. I'm having to reinstall roms every few days to have a working phone. I did have the pogo battery cover on for most of that time. Last time it happened, I removed the cover and I suddenly had a connection. I've left it off since, hoping it was just that but sadly not. Happened again to me just now

Hi, have you flashed any different radios? What's your current software version and does your Wifi drop as well? Or is it just mobile data?

After the 2.17 OTA update, the signal is always medium...but now there r no call drops or loss in signal

sandipbarik said:
I got my 2.17 OTA update last night, immedietly after the update my wifi signal was dropping, which was pretty stable 3 bars before that.
Today morning im getting dropped gsm signal...sometimes its showing no signal...eve a manual signal search gets me no network, omly airplane mode on/off gets the signal back.
I m not unlocked and not rooted...just plain factory stock.
should i unlock it and flash the radio from the 1.29 rom ??

That's up to you, but many users have experienced that some radios work better for different people. 2.17 works ok for me, maybe you should try.

Defy+ Plus phone and data hang

Hi all, I posted in the CM10 support thread, but this issue doesn't seem to be well known so I'm raising it in its own thread.
I'm not having much luck with my newly-purchased Defy+. The factory firmware suffered random reboots, which is pretty well documented. I installed the latest CM10-20121018-NIGHTLY-mb526.zip, and the random reboots have stopped. However I now get occasional dropouts of phone and 3G service.
Usually, I find out when either I try to use data and even though the 3G icon suggests a connection, no data is transferred. Then the phone app hangs when I try to make a call. If people call me, they *do* get a ringtone, but my phone doesn't make any sound or visual feedback that there's a call coming in. Aircraft mode doesn't rescue the situation, I have to reboot the phone to get it to work.
Hope someone can help - I came from a rock-solid CM7 / HTC Desire HD setup, and this is doing my head in. Am happy to provide any more debug information as required.
NB I see from http://forum.xda-developers.com/showpost.php?p=31440310&postcount=321 that there is a known 3G data dropout bug on these phones, but that's not what I see - I can't make phone calls either. Plus my ROM has that fix in.
I have installed Connection Checker which will hopefully give me details of if there's any pattern to the problematic behaviour. Look forward to any feedback, thanks in advance.

Change baseband. I had the same problem. It's solved changing the baseband.
Mine was Europe\central Europe\3.4.x or 3.4.2-145 changing to 2.21 no problem at all.

Thanks for the response, it's interesting and heartening. I can't find a factory SBF so I can't take it back to the shop.
FWIW, I find the baseband screen confusing. My service provider is Golan Telecom. They have a UMTS 2100MHz network, and rely on roaming with another local provider - Cellcom for GSM 900/1800 and UMTS 850/2100.
I think I understand the frequencies but not what the 2.21 etc means.
As I type this, the phone has been on 2.21 for 20 minutes, and is now exhibiting the problem again.
I am now trying Asia / China 0.26/1.10 which has frequencies 850/2100 MHz. If for no other reason than Israel isn't listed in the list. However, that didn't work for long, if at all. I'm absolutely hating this.
Can you or anyone add to this by suggesting how I might choose the right baseband out of the options given?

Try one by one according to your location.

Well, my location (Israel) isn't in the list. I've tried many settings, with varying results, but not one has been able to avoid this problem where the phone (app as in the actual telephone) just hangs and I lose voice and data. I can keep going, but I don't understand why one would magically work. I think 900/2100 should work with my SP, and I don't understand the differences between the myriad of options that still result in the same frequencies. Have I missed something?
Is there anything else worth trying? I have heard that sometimes it can be a SIM problem, but my SIM isn't even a year old.

I think I have a fix, due to great work by coas (see http://forum.xda-developers.com/showpost.php?p=31025913&postcount=34).
My carrier (Golan Telecom) has a national roaming agreement with Cellcom. It seems that flashing the Cellcom radio for the Defy Plus has fixed the issue. It's been up for four hours now, which is four times as long as before.
I guess the issue is that flashing the SBF to root the Defy Plus, messed up the radio in some way, but I don't really understand the whole radio issue, and what is different in radios from different carriers' firmware. I thought GSM was GSM and UMTS was UMTS. Anyway it seems to be working so I'm not complaining.
Just wanted to put this here for the benefit of anyone else who might be having the same issue.

Sadly, it was a short-lived "fix". Still unreliable, just not quite as bad. I'm going to try the Orange (Partner) radio .sbf which coas tells me is updated, and if not, then return it to factory firmware and take it back to the shop.

If you are willing to stick with a Custom ROM, you can try a different setting on the CPU Settings.
Not a long time ago, I had similar problems and solved it enabling "load all modules" and "conservative" settings in the custom recovery.
Good Luck and let me know if it worked for you.

Hi, thanks for the answer. I didn't update the thread, but I can confirm that I took it back to the shop. The guy knew about the problem and replaced the handset, and now it's fine. So it's a hardware issue - he said it happens on around 1 in 5 Defy Pluses.

Hi, I had the very same problem with my defy+, it suffered that issue on CM9 and CM10. I could not resolve it and had to go back to stock, it works fine now.
It seems the problem is more frequent with national roaming in use.
After the replacement, is everything working fine even with CM10?

[Q] Still have that signal issue... Any advice appreciated.

First off, I've read dozens of threads relating to this issue and no one seems to have come up with a solid, concrete answer, apart from returning phones for a replacement (and often still having the issue).
I recently acquired a Gnex second hand that has presented the signal loss issue. I am coming from a Nexus S which gets full blue HSDPA bars of signal indoors on my desk. When I place the same sim into the Gnex, I get nothing but an X. Every now and then it registers on the network (Showing "YES OPTUS" - my provider here in Australia), but still no signal.
When I got the phone it was running Android Revolution HD 9.0 with a non-stock kernel (I didn't take note before wiping the device). No luck there with signal. I then flashed to 4.2.2 under Android Revolution HD 10.0. Still no signal. Since then I have tried:
- Lean Kernel
- Air Kernel
- SlimBean Rom
- About half a dozen different modems/basebands, local, european, north american, etc. Finally settled on XXLA02 as that was recommended for Australian users that aren't on Telstra/Vodafone (850MHZ).
- Matching RIL's to the basebands
None of the above options made an improvement. On the air kernel, I would see the signal (using *#*#4636#*#*) chance from UMTS to EDGE to GPRS to HSDPA to EDGE etc over and over, sometimes showing one grey bar on Edge. I could go outside and see one grey HSDPA bar stay there, but you still couldn't use data. Browsers would fail and the playstore wouldn't open without a connection.
As of today I have restored the phone using fastboot to the earliest available Google factory image (4.0.4). I unrooted the phone and relocked the bootloader, just back to complete stock. The modem that comes with the google image is XXLA02. In this current state, there is still no signal inside, where I would have full bars on the Nexus S, but when outside fiddling with the service menu, selecting AUS from the GSM/UMTS band selection menu gave me a reasonable HSDPA signal. Though it was erratic. It would fluctuate from 3/4 to 0/4, to 1/4 over and over and both upstream and downstream indicators would be going, yet nothing was coming through.
Trying to open the playstore was awful, but it eventually worked. I managed to get the Speedtest.net app down after a few failed attempts and ran a test to the nearest OPTUS server. The results came back as:
Ping: 235ms
D/L: 576kbps
U/L: 35kbps
Which is not very good, really. As soon as I walked back inside to get the Nexus S, though, the signal dropped right away to nothing.
I took the sim out, tried the same test with the Nexus S in the same spot outside and got the following results:
Ping: 145ms
D/L: 2241kbps
U/L: 1169kbps
Which is a bit more typical for the area.
So I'm running out of ideas
As the phone was bought second hand, I don't have anywhere I can return the phone to for a replacement. Unless I contact Google directly, I don't think that will be of any help, really. Is there anything else left I could try, or is this just an expensive paperweight?
Thanks for reading.

When I got the phone it was running Android Revolution HD 9.0 with a non-stock kernel (I didn't take note before wiping the device). No luck there with signal. I then flashed to 4.2.2 under Android Revolution HD 10.0. Still no signal. Since then I have tried:
- Lean Kernel
- Air Kernel
- SlimBean Rom
- About half a dozen different modems/basebands, local, european, north american, etc. Finally settled on XXLA02 as that was recommended for Australian users that aren't on Telstra/Vodafone (850MHZ).
- Matching RIL's to the basebands
None of the above options made an improvement. On the air kernel, I would see the signal (using *#*#4636#*#*) chance from UMTS to EDGE to GPRS to HSDPA to EDGE etc over and over, sometimes showing one grey bar on Edge. I could go outside and see one grey HSDPA bar stay there, but you still couldn't use data. Browsers would fail and the playstore wouldn't open without a connection.
As of today I have restored the phone using fastboot to the earliest available Google factory image (4.0.4). I unrooted the phone and relocked the bootloader, just back to complete stock. The modem that comes with the google image is XXLA02. In this current state, there is still no signal inside, where I would have full bars on the Nexus S, but when outside fiddling with the service menu, selecting AUS from the GSM/UMTS band selection menu gave me a reasonable HSDPA signal. Though it was erratic. It would fluctuate from 3/4 to 0/4, to 1/4 over and over and both upstream and downstream indicators would be going, yet nothing was coming through.
Trying to open the playstore was awful, but it eventually worked. I managed to get the Speedtest.net app down after a few failed attempts and ran a test to the nearest OPTUS server. The results came back as:
Ping: 235ms
D/L: 576kbps
U/L: 35kbps
Which is not very good, really. As soon as I walked back inside to get the Nexus S, though, the signal dropped right away to nothing.
I took the sim out, tried the same test with the Nexus S in the same spot outside and got the following results:
Ping: 145ms
D/L: 2241kbps
U/L: 1169kbps
Which is a bit more typical for the area.
So I'm running out of ideas
As the phone was bought second hand, I don't have anywhere I can return the phone to for a replacement. Unless I contact Google directly, I don't think that will be of any help, really. Is there anything else left I could try, or is this just an expensive paperweight?
Thanks for reading.

I would update to the latest OTA update and verify you have the latest radios.
Edit: also make sure your sim card's contact points are clean and making a snug connection.

Resigned to just getting rid of the phone. Will try and get a newer revision of it without the signal issues.

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...

possible solutions:
- get new sim card
- hard reset done inside stock recovery

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.

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..

No ad blocker.
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'
