[Q] HSDPA not working, but EDGE - One (M7) Q&A, Help & Troubleshooting

Hey there,
two weeks ago my HSDPA suddenly stopped working.
EDGE is working fine, but whenever I enable HSDPA (selecting "GSM / WCDMA automatically" instead of "Only GSM"), it shows a "H" in the connectivity bar,
but I have no internet (Connection reset). The icon rapidly switches to "3G", and then disappears after a short time.
Could it be some hardware error? I have tried different roms (CM10.2, Google Play Edition 4.3), but that didn't change anything (Except it shows "H+" instead of "H").
Also I hadn't had changed anything when the error occured, so maybe there's just something broken?
My phone is rooted (S-ON) with hboot 1.54. The error occured when my phone was non-rooted (stock), and I just rooted it to check if it would occur with other roms.
I could not check another sim, yet.

I am having same issue: http://forum.xda-developers.com/showthread.php?t=2502367. It seems it is provider related, i.e. if your carrier does not support fast dormancy the phone acts like this. I have a friend with a One X and another with SGSII and they are having the same issue on Orange RO.

Well, but it worked when I bought my phone, and then (two weeks ago) suddenly stopped working .. So I'm not sure if it's a carrier problem .. Could it be just my SIM card is broken?

my Kaiser do not work with 3G only works on GSM

Suddenly it had happened; NO 3G nor GPRS data transmission. I can see the 3G sign , but when I make calls the phone disconnects; when somebody call me, he received a message that my phone is off line. Only when 3G signal is on. But when normal GSM is on, everything will be OK. My phone can not get data from the internet, even though it shows that is is connected. I tried all of the above solutions to fix this problem but no helpand sometimes it shows 3g sign but as soon as i try to call some1 all the signals are gone.. I tried to hard reset and try it before installing any software, no help. I tried mostly all available ROMs and Radio ROMs; even the original, but not fixed. I do not what to do. Now, I am using the phone with GSM only, NO 3G. Please help!!!

Hi there nunu,
I had the same problem, went back to the store and nope not a known problem.... So I started to troubleshoot this
1. normal G connection
2. 3G appears or even H
3. signal lost and after 30 sec. the cycle starts again.
what worked for me was the changing the of the radio version. I am currently in the Netherlands and here the NEON_Radinly_1.65.24.36 works fine, I confirmed it by loading a rom with a different radio in it and the result was again the same.
hope this helped in any way...
Let me (us) know.

life is good, but life get's much better with a Kaiser
are you trying to connect with [email protected] / cingular1 ?
this is the kinda information you should have put in your first post
I use the above and have zero problems in Philadelphia
My 3G went out for like a day here (Phone only worked on Edge), then it started working again. Cellular carriers do have outages from time to time. Has it been a long while since it stopped working?

Flash to a different compatible radio. If you do not get 3G/H service back, then you have a hardware issue with your radio, and will need to have the phone serviced.
what newtwork are you on?
have you tried your sim in a different handset?
what happens when running in gsm only mode?
in settings phone network change selection to manual and tap find networks and reselect network (this is known as a manual roam) does this make a difference?
Same here!, im in montreal, canada with Rogers, and in 3g doesnt work, it detects the 3G network, but as soon as i try to make a call or go on the internet it looses the signal and i have to go on GSM mode.
and i'm using LKDV12 but i still had the same problem on AT&T Original rom, and Dual V2.
Anyone?
Major problem --
I have been travelling round the world for a year and have the same problem, Have tried many radios, if I use 3G( wscdma) or auto band then the signal drops everytime i try to make a call, and no data is possible however if I use gsm only data and voice work fine, thease symptoms are on many networks, Chile, Easter Island,Tahiti, NZ, Fiji, Optus ( OZ ), and m1 ( singapore ),
Radios tried
EMO 1.71.09.01
Neon 1.65.24.36
1.65.21.18 ( att )
I even loaded the generic dopod rom + radio and it didnt seem to help.
Is it possible something low level has changed whilst doing all this flashing ?
Or could the Hard SPL affect something.
I always try to buy a 3G USIM in each country and test the sim in a backup G800 to ensure the carrier has enabled 3g data okay.
Phone is Kaiser ( HTC TytnII )
ROM is varied but and usually lorentis series roms -- L26 12 light atm
Symptoms, 3G icon shows but data wont connect, if you try to call radio strength bar drops to zero and cell communications are lost , sometimes reestablishes comms but often needs soft reset to band switch to work.
If 3G icon not showing all calls and GPRS data works Okay.
Personally I would not expect this to be a hardware failiure as many others are experiencing teh same fault and for working hardware to fail in use is more erratic in the failiure mode, but a low level register, or some other type of protocol corruption could easiliy be the cause......
The proven "high GPS current consumption in standby" issue is also present as it seems to be on all Kaisers but afaik the root cause of this was never resolved either .....
my Kaiser do not work with 3G only works on GSM NEED HELP

i have the same problem did you make it work how you set a gsm band instead of the 3g on the phone tks for your assis
dr.vogel
I have the same problem. Already had it with WM6.0 original HTC ROM (Finnish ROM, but language set to English). Then sent it to service. It came back, they said they "reapplied software or smth" and it worked after that. Then after 6.1 update again, the same problem (even with the latest updated Radio ROM).
When I set band selection to auto, it picks up 3G or even H but tends to loose it and definetly looses connection to network if I try to make a call. Can't take any incoming calls either.
It works ok when I force it to use GSM (EDGE for data) on Band selection tab, in phone properties.
I probably won't bother taking it to service anymore cause there is no local service here in Estonia, they ship it to Finland and it will take a minimum of 3 weeks...
... so I'm waiting for Xperia X1 and hope it's not as much HTC.

Hardware problem, repair needed and unavoidable to get 3G functionality back.
I have the same problem.
I bought an O2 Stellar (Kaiser) from a work colleague and it worked fine on 3G/Auto on the day I bought it.
The next morning, when I switched on the phone, it had exactly the symptoms described (i.e. it would only work if forced into GSM mode).
My colleague took it back to O2 under warranty.
1 week later, it was returned as 'fixed', but it actually still had the problem, so my colleague returned it again to O2.
Another week later, O2 provided a replacement unit under warranty.
The replacement worked fine, until the next morning when I turned on the phone and had to force it into GSM mode again because it wouldn't work in 3G/Auto mode.
I'm on 3 in the UK and I suspect the problem is something to do with the roaming onto Orange GSM which happens when there is no 3G signal from 3UK. However, on the day each of the units worked, it was switching between 3G and GSM repeatedly because the 3G signal is fairly poor in my office.
I'm now waiting for my colleague to return from his holiday so that he can return this unit to O2 and we'll see if we get another replacement. If we do, I'm very reluctant to actually use it - I think I'll probably just sell it on and get something different. Shame because I really like the Kaiser.
as mentioned before, another thing that you should've tried is to call the helpline and see if there's an outage in your area. I've been experiencing the same problem in a very particular area (3G hand-off to EDGE problem only happens on campus). Tried different radios and problem still exist, so I gave them a call today and turned out that there is an outage here.
In my case, it's not caused by a network outage - 3G works fine on my Hermes in the same locations.
Good thought though.
Relax boys...I have'd the same problem... The only solution is to go with your phone for warranty return. There they will change your TyTN II mother board and all will be ok. IT IS THE ONLY WAY.
PS do the same thing I did http://forum.xda-developers.com/showthread.php?t=418375
i post this thead and the solution
i post this tread an the solution came on tha answer of various of you great ideas i get the solution changing the rom and the wm to 6.1 and the rom is the dutty's it has worked almost perfectly in any wy itested only some install on the gps progrms but no mayor problem tks all you friens for a great support
The same thing has happened to me as well (Orange UK).
Initially I thought that it was an outage in my area as my friends had problems connecting to 3G as well, but their problem has been fixed but I still cannot.
I'll be contacting their tech support dept. later today and I'll post back.

No 3G since FRF83

Any solution?
Only GPRS/EDGE does work, if 3G is available, it disconnects automatically until 3G isn't available.
Solution: Set to 2G-Only :-(
Anyone has the same problem?
I didn't have this problem with FRF 72.
Provider: Sunrise Switzerland
Radio: 32.36.00.28U_4.06.00.12_7
Have you tried going into your phone settings from *#*#4636#*#* and setting it to wcdma only? I did that on mine not too long ago and no more dropping to edge for me!

does it lose complete signal? or does it show 3g still but just not doing anything?
Mine was working at first after flash. Then at about 2am it just kept trying to load then times out. Still shows 3g but just dont do anything. Im hoping its just tmobile messing with their towers... I dont see why it would work at first then not now..
The problem is, that i can only have a internet connection, when the phone is logged in into a gsm or edge network.
as soon as wcdma is available, the phone disconnects from the internet.
the signal is always available, but it looses the internet connection when it changes to 3G mode.
when the phone changes from 2G->3G mode, i see for 1s the 3G icon and then no icon will bi there.
when it changes back from 3G->2G, the EDGE/GPRS icon is visible again.

ok thanks for clarification. My problem is different. I think related to phone company.. I still show the 3g signal and even have bars, but the pages dont load and eventually gives me the check your service and try again alert....
So Im hoping soon its working again for me... And I hope you as well figure it out.....
Thank you Good luck!
Had the same issue after update, did *#*#4636#*#* and noticed I was set to GSM only. Set it to WCDMA preferred and now it's good.
Thank you very much, thats the solution!!

Thank you. Updated to FRF83 this morning and I've had a full 3g signal, just couldn't pull data all day. Could over edge. Sure enough, GSM only was selected.
AT&T N1.
I'm having the same issue on a non-rooted phone on T-Mobile. No 3G after the FRF83 update. Full bars of service and 3G displayed in the status bar. Dropping to Edge only works but there is no data with 3G.

Same issue here.
Switching to WCDMA preferred doesn't work for me though.....any help is welcome
I think it's a hardware problem with a lot of N1's.
Mine was ok the first 2 months, and later, 3g not working. This is driving me crazy ):
I have tried everything. Change the simcard, I did a reset of the data with my telcon, and nothing happens.
I've seen these problems on many N1's.
I hope google / htc release a fix for this problem.

how bout checking your bands in the service menu. so *#*#4636#*#* -> phone info -> press the menu key for more options -> select bands -> choose one appropriate for your region (ie "USA BANDS").
If all else fails do a factory reset by going to the settings -> privacy -> restore factory defaults.. of course do a backup/sync/whatever before just to make sure you can get all your apps back.
There's other ways to do a factory reset via the bootloader .. its under recovery and you press up volume or the trackball I think and you can just select all the clear/erase settings there and that should clear out everything on the phone's internal storage.
The factory reset worked for me (via bootloader) when I upped from update-1 to FRF50 and didn't have any data icon next to my signal strength. Could call out but couldn't get data.
Hope that helps.

Check your APN settings. Do a full factory reset from the bootloader. If nothing works you should call tech support again. Most 3g issues where you have issues with connecting are service/signal level related. I *****ed early about my 3g issues on tmobile and it was the network as they've pretty much gone away with improving the backhaul in my area for HSDPA+ or updates to the phone's radio.
HTC is really really really cool about swapping phones and repairing them. If you feel you have a nexus that has hardware issues call them. I did this 3 times already (one time for minor cosmetic issues with the refurb they sent) and I couldn't be happier about how willing they were to replace/repair the phone. It turns out I really didn't have any issues with them at all.. with any issues with hardware from the second refurbished phone. It was service or software related and I'm happy to say with updates/tmobile service improvements I couldn't be happier with this phone.

Thanks blisk, but the thing I don't understand is why Blackberry 9700 with T-Mobile bands, doesn't have problems at all ?
By the way, I rooted my phone , so the thing with the warranty it's complicated
I had it happen last night at work all night, but when i got home i checked my wife's tp2 and it also was doing the same thing so for levity wasn't the phone but tmobile. They started worming the same time also.... I think its tmobile.
Hello, I had the same problem with my imported n1. I'm using the tmobile version non rooted fully stock manually updated to frf83. I did a *#*#4636#*#* and selected wcdma only, rebooted and couldn't connect to my gsm network. Went in again and did a wcdma preferred, rebooted, and I works better, still changes fast to edge and G, but less often, I'm still trying it but I have high hopes its gonna be ok
Mmmm i did have problems with 3G too after pushing FRF83, but i found out that for some reason the APN settings weren't set correctly after the update. In my case the port setting after the proxy of the APN wasn't set, i changed to the correct value and it worked.
In conclusion, check your APN settings.
Just went from FRF72 to FRF83 and it's working fine.
I'm currently set to GSM auto (PRL) in the *#*#4636#*#* and I didn't change it to that after putting on FRF83.

[Q] Milestone is loosing signal - hardware or software error?

Yesterday my Milestone dropped the network and wrote "Only emergency calls". On other phones there was maximum signal. After a while the phone logged in to the network, but lost the signal again. I thought something is with the ROM, so I made a factory reset but didn't help. I flashed the correct SBF file (first Éclair, then Froyo), but didn't help. I restored an earlier MOD I used without any problem but didn't work.
I always used the German baseband files with other MODs because my Milestone is German.
The problem is that if I make anything (I mean anything related to the data connection), the GSM signal disappears, sometimes data connection remain with no problem, sometimes it is lost, too, but sometimes it has GSM signal with only EDGE network. If I do nothing, just turn off the screen and do nothing, everything goes back to normal, and the phone has normal data connection with GSM signal, I can make or receive phone calls.
I put in another SIM but the issue was the same.
Can I try something related to software and didn't try yet or this is a hardware failure? And if so, what is the price of a GSM module? I couldn't find it.
MOD: It seems that only the 3G is not working (sometimes HSPA does while 3G phone connection don't), with 2G there isn't any problem.
dial *#*#4636#*#*
Under phone info, try a different network type.
It probably defaults to GSM (auto). It does on mine anyway and it's fine.
But maybe WCDMA preferred, GSM only, or WCDMA only will work better.
It depends on which is screwing up... the WCDMA or the GSM
edit: had the dialpad code wrong... again.. geez

Are you sure you have applied the correct baseband?
I would tell to re-apply thru AOR.
Sent from my Milestone using XDA Premium App
You could go to settings, wireless and networks and somewhere there there is use only 2g networks and if that is checked, you could try to uncheck it. That is what happened to me before on the froyo mod. Also, you could try turning on airplane mode, then turn it off. Good luck
I always used the German baseband, tried to switch 2G/3G many times, applied the baseband trough OR, applied the RTEU baseband, re-flashed the ROM, the original Éclair, the Froyo, again and again but nothing helped. I gave up I decided to go to the service. Before that on a forum somebody asked something, I gave an answer but I was not 100% sure about it, so I flashed the RTEU Froyo.
And it worked. The 3G, HSPA, 2G, EDGE, phone functions all are working now. My phone is truly German, it has QWERTZ keyboard and the original ROM was the ROM from Deutsche Vodafone (tried that one before, too), it has the logo on its box, and the German baseband files always worked. I don't know what just happened, it's simply working now. Why now... don't know.

[Q] Mobile Network Type: UNKNOWN:0

I got a problem with my data connection.
I got on another city last day with 3G connection, and it started to get weird, changing from 2G to 3G constantly, very unstable, then after some time, the icon "E" or "H" disappeared.
I checked the Mobile Network Type under Phone Status, and noticed that is UNKNOWN:0.
Services, IMEI, and other related stuff is OK.
Any thoughts about that?
Try to enable Airplane mode and then disable to reconnect to the mobile network.
I did the Airplane mode plenty of times.
Plus, I wiped all data and cache.
Did a Factory Reset
Played a bit on *#*#4636#*#* secret menu...
What is weird is that my mom phone's (same model) got the same issue.

Weird.
I played a bit more on secret menu, but no go. Then I restarted the phone ( I was did it already earlier) then worked.
But, it worked for some hours, and the radio restarted alone and it got broken again.
Now, after doing some non related stuff i got it working again.

I have had this problem and searched everywhere. I finally found how to fix. Hope it works for you. Someone posted somewhere that SELinux was set to "Enforcing". YOu have to change it to "Permissive". Once I did that my network issue was fixed. You can download a Lunix Modifier from GPlay Store.
Go to your settings and the "About device" section and confirm whether or not your "SE for Android status" is set to "Enforcing".
My phone also same issue can you help me. I chenge several times secret menu network.

Weird.
I played a bit more on secret menu, but no go. Then I restarted the phone ( I was did it already earlier) then worked.
But, it worked for some hours, and the radio restarted alone and it got broken again.
Now, after doing some non related stuff i got it working again.

[Q] General Mobile Data Issue, Baseband Problem?

Hi at all.
This is my first Post, but i cant get any further with my Problem.
I used to have cm11 on my I9305 (T-Mobile Germany), everything worked fine (more or less).
Last Month from one day to another my Baseband completely disappeared without any obvious reason.
Luckily I had a Backup that worked with unofficial cm12 rom.
After that nearly everything worked.
Now, since 2 Days i got a new Problem. Everywhere where I got 4G, my Mobile Data work. But in Areas where I only got H+, 3G, Edge,
I have to switch my preferred connection to 2G, else my Data wont work. Sometimes for Seconds i see the 3G Logo, light up the Status Bar.
But I got no Connection.
The Strange Thing is, that when I call Someone, during the Call, the H+ Connection seems to work, but after the Call, it disappears.
And my WLAN Connection works only after every reboot (Connects, but no Internet, Also very disappointing)
Things I did yet:
-Flashed various Modems for I9305,
-Flashed different Roms (CM11, Nameless Rom, Resurrection Remix)
-Smashed the d*mn thing against the Wall :angel:
Information from my Phone:
-Baseband Version: I9305XXALK2
-Mobile Network Type: UMTS (it shows that, but no connection)
-Mobile Network State: Disconnected
-IP: Unavailable
Has anyone encountered a similar Issue, or a Solution?
Could it be a Hardware Problem?
EDIT: IMEI is okay. I try and try, but nothing seems to Work...
