[Q] No 3G or HSPA+ please help - G2 and Desire Z Q&A, Help & Troubleshooting

I am currently running my G2 (T-mobile USA) on Gingervillian 1.4 and set my phone to airplane mode for a while, soon after turning it off I am unable to gain 3G nor H+. Even through the wireless and settings my data is checked as enabled. Does this have some thing to do with the radio? I am quite an amateur when it comes to this problem, please any help or solution to this i would gladly appreciate.

Have tried a reboot? Or maybe taking the battery out and turning it back on

[Q] 3g not connected...refurb phone

Hey guys quick question.Just got a refurb incredible and it doesnt detect 3g at all.Talked with the VZW suport for 45 minutes.Went through all the troubleshooting steps 3 times over,did master resets...everything.They're doing a line resolution to this phone to see if it resolves the problem.It is not bricked,I can send/receive messages and make/receive calls.Would rooting it maybe help?The support rep said I might have to have the original software reflashed onto it from verizon.Any help would be greatly appreciated.
Are you in a heavily cemented building? I noticed today that my 3g died and wouldnt reconnect no matter how many times I resetted and battery pull, while I was in class because the coverage and signal just doesnt penetrate the building.
No I was on my house.I even went outside

The only thing you can do is turn airplane mode on and off or check the 3G internet connection button in networks.
If that doesn't work the phone is broken, but you can try re-installing an RUU if you want but personally if it was a refurbished phone I wouldn't even bother and I would just get another one.
I tried the airplane mode trick and still nothing.the mobile network button says mobile network turning on but doesn't ever connect.what is an ruu

Data Not working...... Help !

Been flashing the DHD for about a year now and never had a problem with it.
S-OFF ENG etc, running MDJ's 3.1.1 ROM.
Not flashed the phone for a week or so but as of this afternoon my mobile network just sits at "Turning on.."
Will not connect data.
Wireless OK. just no data.
Ive not messed, installed, uninstalled anything for a while and this morning it was working ok.
Anyone got any ideas ?
+1. Same here. Was working fine, then I noticed the data icon was missing.
Have tried different roms, radios, etc. But no joy.
Any help, gratefully received on this matter.
Just out of interest, what network are you on?
Edit. Definitely something wrong with Orange. Unable to connect to my account with the Orange app.

I have had the same problem, but had related it to a dodgy data import from MyBackupPro as it was working and then wasn't. Nothing I did would bring it back apart from a factory reset. I didn't reload the data and it's been OK so far but it could be a similar problem.
I am on stock Gingerbread.
Just flashed a new ROM, problem solved. Couldn't be bothered waiting months no doubt for orange to update to 2.3 and put all their crapware on it.

?
by saying no data you mean in 3g networks?
Yeah 3g

see if you stuck NPC data in the phone company
I’ve experienced this too when I was in some areas, it happened in place you’ve been before and used 3g?
In my country whenever I go to the beach I lose 3g network and it keeps trying to connect...
Probably you know it, but...
If you use widget to turn on/off your data, and if you changed ROM from older to Gingerbread, it seems that this doesn't work. It is partially true- widget doesn't work anymore, but you can still turn on/ off your data from upper dock -> quick settings -> cellular network data (or something similar )
Me too, and I'm running stock 2.3.3 on Vodafone UK. No icon by signal strength bars, although apparently signal strength at -75dBm.
I can force it into 2G by selecting GSM only and the icon comes back, but not so for WCDMA only.
Also noticed in Quick settings from pull down notification bar that 'Mobile Network' is always 'Turning on...' and won't toggle.
Any ideas?

3G connection uses a LOT of power

Hi everyone. I'm running Trip's CM9 with Franco's Kernel r9 on the Three network in the UK.
I don't get much signal at home, so usually leave airplane mode on and just use Wi-Fi. When I do this, I can get 4+ hours' screen time with games, browsing and more. When I work and have the 3G connection on all day, I struggle to get 2 hours!
Since 3 don't have much 2G coverage in the UK anymore, I am unable to leave the phone on 2G only.
Is this level of power use correct? Or could it be a ROM/network issue? Anybody else seen a similar issue?

3g will always use alot of power. have u set ur gsm to auto or wcdma preferred?
Well unfortunately if I do that, there's a bug using custom roms on Three network at the moment where if you lose signal there's a chance it won't come back until you enable then disable airplane mode. To get around this bug, I've had to set mine to WCDMA only

Signal problems & Battery drain

Hi.
Has anyone else had problems with signal, specifically related to the data network on their One X?
I'm finding my phone is switching to 3G, G and E bands too often, sometimes I only get E band where I had a full H band signal on my HTC Sensation and on anything other than H nothing like web pages or anything will load anyway.
I also find the battery life is draining incredibly quickly at the moment too.
I've tried different Roms, currently on ARHD with latest test base and it's still a problem, was on that Venom ROM before and having the same problems although with ARHD the battery life does seem quite a bit better.
Anyone have any ideas?
Cheers.
Anyone? My data connection keeps "disconnecting"
Did u try flashing the original ruu again? This should fix it and then try rooting again.

Try changing from auto GSM to 2G only. If you are away from the 3G tower, keeping a 3G connection consumes a lot of battery
Since both ROMs you mention are using the 2.05 test base, it might be an HTC related issue as well.

I live in Manchester city center, I should be getting a constant HSDPA signal.

[Q] No automatic switch between WiFi and 3G

Hello,
hard to describe my problem. Normally WiFi as well as 3G is turned on. At home the phone is using WiFi but when I leave home and do not have WiFi anymore it often does not automatically switch to 3G. I still have coverage indicated by the status bars but the H is missing. As a workaround to bring 3G back I can either switch between 3G and 2G or go into Airplane mode and back.
However, both solutions do not satisfy me. I want to understand why this does not happen automatically.
Thanks
Stock ROM? Rooted? Please answer these questions before posting a question...

I installed the unofficial CM9 and already downgraded from 3.35.20.10 radio to 3.35.19.25. Without success.
Might it be related to HTC Smartsync powersave issue, though HTC Wildfire Buzz should normally not be affected?
SmartSync is different.
Why didn't you have success when downgrading the radio?
No success in the sense that the problem still persists. Any ideas what I should try out?
I should maybe try out a different ROM. Maybe it's a problem with my operator.
Try a different ROM
I could resolve it by reducing the number of APNs to one.
