[Q] T-Mobile G2 on AU - Vodafone - G2 and Desire Z Q&A, Help & Troubleshooting

Hi everyone,
i recently picked up a G2 on a US trip and am currently trying to set it up to work on the AU vodafone network.
i have gone through the sim "unlock" process, so it should be free to accept any sim card. (it also doesnt prompt me for an unlock code anymore, so im assuming it worked)
when i put the vodafone sim card in the phone, it detects the sim (there is the sim folder in the menu, with the vodafone sim options) and when i use "*#*#4636#*#* i see that there is something in the signal strength (-97dBm 8 asu).
BUT
when i goto settings ->wireless & networks -> mobile networks -> network operators i get an error saying "error while searching for networks"
any ideas?

Shouldn't this be in the G2 forum, not the DZ one ?

Thread moved to G2 General.

I am very interested to know how everything works out for you when you get it resolved.
Im moving to Melbourne from San Francisco in 3 weeks and I am on the fence if I should get a Iphone 4 or a HTC g2
*currently own a HTC Evo ..sadly i have to sell it

welcome to the club my friend
Unfortunately we have the same issue as you but we haven't find a solution yet. So far i have figured out that the phone after unlocking cannot read properly CID and MNCMCC codes from sim.

jee... sounds like the club to be in

5 days now i am trying for a solution. So far nothing to say. Just that users with same problem increase day by day. This might be good as htc will have to pay attention.

i dont know if its me, or if anyone else has noticed this, but if you change the band (auto - USA - Euro - Japan - Aus - Aus2)
then go and try to search for networks, the speed that the error comes up is different... its always the same error though....

You are right about that.

hi, i guess i need to join this club .. any progress for the solution?

I'm using a G2 on Vodafone AU and having no problems at all ...
If I click search networks it sort of just stops immediately with VodafoneAU down the bottom.
The one issue I'm having is that numbers are formatted for US ... anyone know how I change this?
I'm not sure if this is a real long-shot but I had some strange problems with my old Vodafone sim in a HTC Magic. I ended up just going into a Vodafone store and asking for a new SIM and the problems vanished immediately. They give you a new SIM on the spot free so it may be worth a try?

Is your phone working unlocked with the tmobile sim? If it isn't you're got the problem a lot of people have been having with unlocking the G2.
Otherwise, try rebooting your phone with your AU sim search for networks automatically and enter your APN settings. Alternatively if it doesnt find networks, go to Vodafone to get a new sim card. I'm also on Vodafone and I'm not having any problems with my current Tmobile Phone (Cliq) and G2 coming in the mail

Fixed by rooting and gfree
Hi! I had this exact same problem: unlocked a T-mobile G2 bought in the US so that I could use it on Greece's Vodaphone network. After unlocking and trying to check for networks, it would just say "Error while searching for networks".
Solution: I found the solution here: http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Subsidy_Unlock.2C_SuperCID.2C_and_Radio_S-OFF which describes an extra security measure that was taken on these phones and why you get this error because of it. The fix, described in detail on that page, involves routing your phone and then running a program to change this security "feature".
I followed the directions on that wiki page and it worked perfectly! It now connects to my vodaphone network here, and can see other networks that are around.
Note that as this is altering the software on your phone, it probably voids any warranty. But, I'll say with my US t-mobile G2 it worked very smoothly.
Hope this gives some insight to any others having this problem!

help to unlock XDA Exec

Following Buzz's installation instuctions I am stuck with these two items.
9. Activate Radio even without Sim in it saying something about no Sim)
15. Flash your original Radio ROM. Do not upgrade the bootloader until you restored an original radio rom.
I think I am just about there with number 15 (with the resource on this site) but can not find anything on #9.
I know a lot of people say that it is already unlocked, but it seems unlocked to a few networks.
Regards
hi, XDA Execs should be unlocked
Does it ask you to enter the unlock code if u enter another sim?
If it doesn't then it's unlocked as far as i know.
What makes you believe that it's locked to a few netwroks, maybe it's because you're trying to find a non-existent umts signal...
Turning the radio on means turning flight mode off (and for the purposes of unlocking you do that without a sim)
Hope that helps.
I take it the UMTS is another name for 3G. My BT account is a normal non 3G account. Is it a case that I need to alter some of the settings, the networks it lists are...
@VF-UK
@ O2-UK
@ Orange
Is ther anything I should try....
umm, what happens if you insert a non-o2 sim into your phone?
If it's continually searching for a signal, it might be trying to search for a dodgy 3G/UMTS signal
in which case try going to phone settings, then in the band tab , select GSM instead of auto or wcdma
In the worse case scenario, if/when you flashed the radio 0.00.00, you might have had some problem with your USB (See the unlocking thread)
Thanks for all your help.
I think I have now got to the bottom of this. The fact is that BT use the VF network. The phone logs onto this, so I guess this is normal. However the signal strength never gets above 2 bars, is this normal?

Not anymore, dude. BT sold BT Cellnet (now O2 plc) a little while ago, but now they have started their own mobile service again (called BT Mobile) BUT piggybacking Vodafone's network.

I believe Vodafone are the only company that downloads the APN settings automatically. For other networks you need to phone them up and they will send the APN settings to the phone manually.
Orange sent me mine automatically as it was an unbranded phone.
Google should provide you with the answers anyway
If the phone is unbranded it should ask you the network the SIM card is on as the phone already has the APN details in it

No service?

This is a weird one.
Just bought a Desire HD, the guy said it was unlocked. It come with a Orange sim card inside. It had a signal.
I took it out and stuck my giffgaff sim card in there and it says no signal, not "network locked".
So i tried texting my mate, and it sent some how after saying that it had no signal. So sometime later i get a reply saying "Sup" from him.
It still says no signal. I tried another giffgaff sim and that also says no signal. i tried a Tesco mobile sim and that says no signal.
And somehow, without the wifi on, it downloaded a htc update.
I then tried the original Orange sim and it still works.
What the heck is happening?
Thanks

Sounds almost as if it's network locked, or that the data network is set to use orange only Settings>Wireless & Networks > Mobile networks >network operators. If that doesnt work you could always try the advanced ace hack kit (Google it, as it's no longer available on XDA) to give you super CID which will allow it to work with any network.

Ive tried choosing 02 UK as the operator and it says "Your sim card doesnt allow connection to this network"
Now, I don't get this. I'm replying to this from my Desire that says "emergency calls only" without the WiFi on and not connected to anything. What the heck????

Yes it is rooted. Well, it wasnt but it is now.
Bump.
My DHD is running:

And it still says no signal with my giffgaff sim. But works fine with an Orange sim card.
Ive unlocked the bootloader just via the HTCDev site.
Please help...
Thanks
If you unlocked the bootloader to flash roms, relock it and unroot using the ace hack kit. It's going to save you a lot of trouble.
Regarding your giffgaff sim, no idea.
Google to see if there is a way to find out if you are actually sim unlocked.

Oh ok.
I wanted to try and flash anither radio to see if my giffgaff sim would work then, will it make a difference?

Nono..... Do not flash a different radio. Do not experiment. First find out whats up with your cell.
I edited the previous post.

Right, i have SuperCID, and that means unlocked? (hope i am right)
I shall check it again.

silly question but have you set the APN correctly ??????
noticed your already getting assisted on GG forums why do you need multiple forum assist ????
I need multiple forum assists as i dont know if it to do with the network and my sim or the phone.
The APN is set correctly, my phone shows no signal, all the time, with a giffgaff sim inserted.
But the very strange thing is that, sometimes it will let me use the internet. And i am not connected to wifi?
Ive contacted htc with my problem and they just said hard reset, which didnt change anything.
Still have the same problem...
And i cant find any solution...
Can anybody help me!?
Bump!??!?!?!?!
Have you tested a different sim on your phone? Does it work?
Have you tested your sim in another phone? Does it work?
Who do you think you should contact?
Sent from a dream.
Decided im gonna sell this DHD and maybe get another one.
No one has helped me with it so im guessing no one has had this problem. Ive tried everything, so the phone is going on ebay.

No Manual Selection of Network

Hello I have an odd problem. I have an unlocked ZL which has been working fine on AT&T in the US. I travel to London a lot and have the international data option on my account and has always worked fine with my other phones. However after arriving in London my phone is stuck on Everything Everywhere (EE) and they don't have a roaming agreement with AT&T. This would be an easy problem to solve by manually selecting a different network but this is my problem. On my phone network selection, below, APN is not showing up. I originally thought this may have been disabled by the original network (Indonesia I believe) so I flashed the US generic firmware and Nordic but nothing I do makes it show up. Anyone else have this problem or solution?
Thanks

Its DISABLED by your AT&T sim not the phone. If you notice by putting another Sim (Non AT&T) You can then use network search. Also ANY AT&T Branded Phone Network Search is LOCKED. I know your ZL is not AT&T branded but your SIM is which is causing it to lock it. My disapers when using an AT&T Sim, But when putting a T-Mobile USA sim or Orange UK sim BAM Network search shows up..
Also I think AT&T has Agremeants with EE , as EE can roam on AT&T here in the USA, EE is basically ORANGE UK, If they did not have aggremeants your phone WOULD NOT connect to the network. Make sure your data roaming is checked..
Thanks you are correct. Crazy considering they wanted me to manually select a network other than EE.
They're support is sometimes ehh. If they had never been out of the county they probably won't know. How is it over there . Always wanted to go.

DINC2 unlocked but doesn't recognize SIM in Panama...help!!!

hi. i just got this phone in the states before coming down to panama. it is verizon, but i called them and they gave me the code and now the phone is unlocked....but i can't get coverage here in panama. i've tried sim cards from a few of the local operators and none of them seem to work. i sure hope someone can help....here's what i've done so far: (oh, pls b patient, i'm a bit of a technophobe)
-unlocked sim. phone gives me sim lock is disabled message....that means i'm good to go, right/
-set phone to gsm only mode.
-software is androaid version 2.3.4
verizon global services told me that everything was as it should be and that the phone should work w/ a local sim card so i'm not really sure where to turn to......hopefully someone here can help. verizon also told me that the phone should work on the frequencies here. i have a claro sim card, but have also tried movistar, digicel, and masmovil. i was told that they use either 850 or 1900.
so, i'm totally stumped. hopefully i'm missing something stupid....btw, tried the sim in other phones (from europe and panama) and it worked w/ them. don't think it's a hadrware problem, but am i missing something? is there a setting change? do i need some kind of software update?
thanks!
update- get cell phone reception w/ gps on
don't know if this will help anyone get to the bottom of this issue, but i realized that when i have the gps on, i get full bar coverage. unfortunately, i can't leave the app on in the background. this makes me think it could be a hardware issue....bad antenna? anyone have any ideas
Same problem
I have the same issue as OP. Got my phone sim unlocked, and it runs on SenseMOD-2012-05-18-225643 Android 4.0.4.
For once I did a factory reset, skipped verizon activation (can´t do and won´t work because I´m not in the USA and do not have a verizon SIM or service), set my network preference to GSM/WCDMA, and the network wasn´t working.
Rebooted, my network is identified as soon as it starts, but then it goes to "No Service". Try to search for network but my carrier does not appear.
Any help?
EDIT:
Playing around with the phone, setting GSM as your network and restarting the phone let me make phone calls. No internet though and the APN was configured correctly. The "E" symbol for the internet blinked once in a while, but never got service.
Also, playing around some more, got my phone to not recognize the network again by removing the SIM another time. This sucks.
