[Q] HTC Desire was unlocked, crashed, now no GSM, help! - General Questions and Answers

Hi, hoping someone can provide some advice on this, been trawling forums and no one seems to have quite the same issue...
I purchased a HTC Desire from someone who had unlocked it from the Virgin network. Had my Vodafone SIM working in there without any problems whatsoever for several weeks.
One night, under heavy use (video streaming etc) the phone crashed, and since then there has been no GSM signal, only 3G. Other SIM cards had the same issue.
At first figured it was a problem with the hardware, so sent it to HTC, but they just sent it back saying 'no fault found'.
Then I figured I'd try a Virgin SIM in it in case it had become 'partially locked' again - though didn't really think such an issue was possible, and bingo - this appeared to work - even in GSM only mode it can make calls.
So I guess I have a few questions:
If I take this somewhere to have it unlocked again, are they actually going to be able to do anything with it? It's not asking for a code, it just doesn't find any GSM signal...
Anyone else have this no 2G but 3G ok issue? Can a crash affect a phone in this way?!
Does it sound like something I can solve myself? I'm loathed to do anything too drastic as it is still under warranty.
If it helps I checked out the simlock menu and it is saying:
MCCMNC file fail
CID file fail
Which I presume has something to do with it...

02 xda serra issue: Am I being completely blonde ?

Im hoping someone can shed some light on a problem that is driving me insane! I've looked/searched the forums but cant find an answer so am hoping someone will answer this thread.
I am on an orange contract so have an orange sim. Ive just been given a new 02 xda serra by my brother. (he bought it for his girlfriend but then she dumped him - her loss; my gain bless him ).
Here's the problem:
Anyway, I unpacked it, switched it on and it ran through the whole set up process and loaded 02 customisation on it. Then i put my orange sim in and is says NO SERVICE. I just get the signal icon with an x. The orange sim works in other unlocked phones. Both PAYG and contract. Other network sims also register in this XDA Serra. Ive tried Virgin, O2, Tesco and T-Mobile - all fine, connect and work fine for calls/texts. It seems that the only sim that doesnt work is Orange!!!!
Here's what Ive done to try and resolve it:
Ive been through phone settings and manually selected the orange network. I get a message saying that it is 'REGISTERING ON THE NETWORK' then after a few minutes get another message that says 'UNABLE TO REGISTER ON THE NETWORK, TRY ANOTHER PROVIDER OR SWITCH OF DATA CONNECTION AND TRY AGAIN'. Ive checked in comms and data connection is off. A message tells me that
THERE ARE NO DATA SESSIONS ACTIVE.
Ive hard reset with my orange sim in - I still got 02 setup and no service with orange. I also noticed that after hard reset it prompts for a network as part of the reconfig/setup process but all the options are O2 and appear to be PAYG. I dont know if that makes any difference. It also has an option to remove all settings, I tried this too but still get no service.
Can you help?
I want to know, if this is a setting problem that can be easily fixed? Have I got something turned on/off somewhere that if I adjust, will fix this problem? Do I need to unlock the handset? [Im a complete novice]. Or is it broken?
Failing that, is there someone around the Portsmouth/Havant/Waterlooville/Hampshire area that has experience of 'cooking' these phones and is willing to help me make it work/set it up with whatever it needs?
If it helps, when I switch it on I can see that:
R: 1.02.25.19
G: 52.33.25.17H
D: 1.90.00.00
If you need any more info please ask.
Here's hoping someone smarter than me can figure this out before I pull all my hair out and end up looking like my dad
Absolutely nothing springs to mind but to stop the O2 customisation happening after a hard reset, perform a soft reset in the three second window when it says "custom configuration" or some similar message. I used to do this on my Alpine and it left me with a working Alpine without the O2 garbage.
It's just possible that stopping the O2 stuff installing, and i am guessing that will also include network settings, may enable your orange SIM to get it's feet in the door and let it all work.
Another suggestion would be to flash it with a network neutral ROM from here. It looks as though the Serra is actually Raphael, aka Touch Pro, so go and search in there.
Good luck and persevere, you will get there.
thank you for replying to my question. I tried the hard + soft reset you suggested and it did get rid of the O2 customIsation but unfortunately I still cant get connection using my orange sim. Network still not registering. Screen shows device unlocked.
Since my original post Ive tried an orange PAYG sim rather than my contract one but still no different. So my problem remains.
Im nervous about flashing a new ROM on my own in case I screw my phone up which is why Im asking if theres anyone experienced nearby who can guide me.
Thank you for your encouragement, I will keep trying.

[Q] WIND Home Connection Problems?

Hey there xdadevs, newbie here. I'll try to keep this as detailed and to the point as possible.
Problem
So I've got a Cincy Bell XT720, and I've gotten it properly SIM unlocked and rooted. I'll go to search for networks, consistently pick up Wind Home, and then attempt to connect to it. I'll select Wind Home, and immediately get a notification that says that "Selected network (WIND Home) unavailable", but it'll continue to try to connect to Wind Home. 1-2 minutes later, I'll get a message saying that "Your SIM card does not allow a connection to this network".
What I've Done to Try and Fix It
- Configure APN settings properly
- Reseat SIM Card
- Load Cincy Bell Stock 2.1/Dexter Froyo 2.2/XDA Special RC1 ROMs
- Attempt everything mentioned in this thread here: (http://forum.xda-developers.com/showthread.php?t=974375)
What I think the Problem Is
- Radio/ROM config problem? Can't pinpoint it for the life of me.
- I KNOW it's not a hardware incompatibility problem, if that's a starting point. This is the Milestone XT720 and not the Motoroi, fully capable of supporting the HSDPA 1700/2100 bands that WIND Mobile uses for its 3G networks.
Any help I could get would be greatly appreciated. Right now, my only fallback is this horrid Huawei U1250...it works, but that's like saying that ramen noodles "works" in comparison to a banquet burger with fries. Thanks a ton in advance guys.
Lol, I'm using a CB XT720 on WIND as well, pretty cool. But yeah, mine is working without any issues. Go into a WIND store, show them your issue, and they should be able to replace the sim card. As mentioned in another thread, WIND had some issues with certain sim cards so that may be why your having the connection problems. If that doesn't help, then it's probably something to do with the phone itself.

At least I know that the CB XT720 does work for sure...I can get WIND to check it out (the SIM was ordered back in December or so last year) or even get the phone replaced via Moto warranty if needs be (somehow, still warrantied until March next year). Thanks for the help!
my XT720 is from sigapore and i'm using it on WIND without any issues
using Dexter's froyo ROM
make sure you get the BLACK version of the SIM card, the WHITE SIM cards dies very often
i've replaced both of mines already, they died on their own, both on my Nexus S and XT720
other friends that i've on WIND also had the same problem, with other phones, they also had the WHITE SIM card
just show them the problem, they will change the SIM card for you.
oh! but you need to go to the Corporate WIND stores, not the resellers stores

Alright...I'm pretty sure I have the black one (black w/ white trim), but it wouldn't hurt to get a replacement. This one's been in a bricked G1, another G1 that got caught in a torrential thunderstorm (you can tell I don't have good luck with those things), a Huawei U1719, and a Huawei U1250. It's probably just got some age on it by now...flaky with my U1250 anyhow, random (relatively frequent) disconnecting, wouldn't connect the first couple of times, etc. Thanks again, be sure to let you guys know how it goes. =.=
Meh, still got a problem. Tried another SIM, went over to WIND...no such luck. I was told that although the phone may be SIM unlocked and it can see the networks on the 1700/2100 band, the radio's firmware may be locked to prevent a connection (the employee had a similar problem with another phone for Bell). Is there anyone on here who can hook me up with an unlocked radio or a WIND Mobile ROM that could help with this? O-^
Hmmm, strange because I was able to connect to WIND Home on the stock CB 2.1 ROM, Khals MIUI ROM, and Mz's CM6 as well. Perhaps, something is wrong with your baseband? I would try this, if possible, get a friend's sim card (anything but WIND/Mobilicity) and see if you connect to that network whether it be Rogers, Telus, etc. If it can connect, then the phone is able to latch onto the regular GSM frequencies. With regards to an unlock radio or baseband, I'm not sure how thats done but maybe someone else on the forum can help you with that.
For some reason, I'll pop in my Rogers SIM (account was probably deactivated though), and my Moto says:
Emergency calls only
ROGERS
Emergency calls only
Go to check my available networks and..."WIND" is the only one that comes up? No idea as to whether its Home/Away or 2G/3G...just "WIND". Not as if it'll let me connect or anything anyways, same flop as the previous attempts ("Your SIM card does not allow a connection to this network"). :/
http://forum.xda-developers.com/showpost.php?p=10001234&postcount=34 - AHA! Videotron and WIND use the same bands (1700/2100), and some digging around turned that up. Looks like they've been having problems too. Can anyone help pinpoint their radio for me? It seems like that might just do the trick.
Update:
http://forum.xda-developers.com/showthread.php?t=944258#11176044 <- Can someone confirm that this is safe for the XT720? If so, my gut instinct's pretty sure this is exactly what I need...the "freq_F_CN_026-850-2100-signed.zip" one appears to be for Canada, while "freq_F_US_342_107-850-1700-2100-signed.zip" does the frequencies right. O-^
Mann, all I had to do was pop in my sim card and off I went. I think there was a 3G fix around here somewhere, make sure to get someone's "approval" first (one of the more experienced guys) because it may damage your phone. Try this though...
Dial *#*#4636#*#*, go into phone information, and see if anything looks off.
As for frequencies, the country does not matter, the frequencies do...for WIND, you need 1700/2100.
do not use those Defy fixes, it'll probably kill your XT720

Whew, alright. Good thing I asked first, thanks. I still can't get it to work properly...I'm more than likely going to have to ditch this thing and go with a G1 or a Touch Pro 2 if I don't have any better luck with it. Thanks for all the help though guys. :/
Have you flashed a sbf? If so, which one? If not did you buy this phone from Wind or somewhere else? If it is a baseband software problem, then perhaps flashing a different sbf will help (Maybe one of the North American ones-- CBW or brightpoint).

STR_U2_04.1E.1_SIGNED_USASHLSTAB14P2XAPCNCBW039.0R_NACBW_P011_A006_HWp3_1FF (Cincinnati Bell)...that's the only .sbf that I can get RSDLite to recognize for some reason. Attempting to pull up one for the UK or the US Brightpoint for example leaves the File Properties section blank and my start button disabled. I have version 4.5.3, if that's any help. Any hope of a miracle here?
Also, I bought it from a third-party in the US...didn't know what carrier it was with, but after some digging around and checking the "S/W" I found it to be Cincinnati Bell. Ideally I'd be looking for a WIND sbf, but I don't think anyone here's managed to get their hands on one. I'm almost at the point of just trying to take it apart to see if there's something loose in the hardware. Someone else on here was saying that there was a loose cable or somewhat that was preventing their UMTS from working properly (can't find the link). Everyone's saying it should be working just fine, I can't really see any alternative besides the baseband perhaps being flaky.

Yup, that's the Cincinnati Bell sbf. The brightpoint one is essentially identical but unbranded--the only differences are things like default webpage in the browser and preloaded bookmarks, etc. I don't know a lot about basebands, but I do know the only way to change the baseband firmware currently is with sbf. I think yours is fine, though. AllGamer is our resident WIND expert, so if his advice didn't help, I'm afraid I don't have much more to offer.
Actually, if this is a Cincinnaiti Bell phone, maybe it's SIM locked to CBW...? I know both of mine are. Does anyone know how to test that? SIM locks are also black magick to me.

Already removed the SIM lock (got that taken care of well beforehand)...I guess I'm on my own then.Thanks everyone, I appreciate the help regardless. :3

i have a hunch you are still SIM locked, that error message ("Your SIM card does not allow a connection to this network") you keep having, kinda of suggest that
an easy way to find out, is to see if anyone have an extra unused Cinncinaty Bell's SIM card, and send it to you, so you can pop it in, and if it doesn't give you any error message, but "R"oaming, then that is a good dead indicator that the phone was not properly unlocked.
also in regards to the stock ROMs
you should have no problem flashing any of the .sbf files
my phone was originally an Asian one, then i flashed it to use the UK ROM, and after that i flashed the Dexter 2.2 to it
So are you saying that its possible that an unlock code can "unlock" the device (pass the unlock code request) and allow it to accept a foreign SIM, but still fail to allow it to connect to the SIM's networks? It'd make perfect sense if Rogers was an affiliated network with Cincinnati Bell (for roaming), since it'd be "mutual ground" between WIND and CBW. And then the SIM wouldn't be able to connect to WIND's exclusive 3G network since it was never on the "allowed" networks as defined by Cincy? =.=
if you are in Toronto, i'll suggest you go to P-mall, any of those cell phone stores there can help you unlock the phone for sure
or you can try your luck online with different ways to unlock the phone
quite sincerely we never really talked much about SIM unlocking of this phone within this forum.
perhaps a DEV might be able to help you figure out how to unlock it for free
because if you go to the malls they might charge you an unlocking fee regardless
although with the chinese places you can argue it didn't work, and they will not charge you for the unlocking

AT&T Nexus S work on a foreign simcard without unlock?

Did you have to unlock the phone to do that?
I called AT&T and they said that they don't have the unlock code since they don't even sell the device, but that it works on sims outside the US. She seemed to imply that it won't work on tmobile but that if I go outside the US, and just put a sim in, it will work without me having to unlock the phone in anyway.
Can anyone verify this?
Thanks

Most customer service representatives are pure idiots .... Nexus S is a Google phone , so it's factory unlocked to any SIM card you use with it(you may or may not get 3G on other networks depending on the other network 3G frequencies , and if the forgein network has 3G on 900/1900MHz it will have 3G on this Nexus S)..
Hope this helps..
Well I went to tmobile and the guy put in a sim into the phone and the phone got no reception nor did it seem to recognize the sim at all.
So it seems that it isn't unlocked.
I tried putting in this code: *#7465625#
Its supposed to tell you if the phone is unlocked or not, but nothing happens, it just says: Connection problem or invalid MMI code.
I don't need it to work on tmobile, but I do need it to work on foreign simcards. And I saw on other forums that for some people it worked on tmobile and others it didn't so there doesn't seem to be any clear answers.

you have another issue here , check your phone
Thanks for the response.
What do you mean by other issue and how should I be checking my phone?
In any case, I put in a simcard that my brother gave me which I believe is from Mozambique on a carrier Vodacom. It asked for the code of the sim when I put the phone is as always, and so I got in putting in 0000.
It then showed no connection to anything whatsoever, also as always.
Keep in mind I did have wifi on.
Then all of a sudden it asked me to update my phone and install something. So I just said yes and it updated and rebooted.
All of a sudden I have bars here and there and it recognizes that tmobile and AT&T are in the area. I also saw I think at the top of the notification bar when I pull down the notifications tab, it said Vodacom. Of course I get no reception whatsoever but that is expected, this sim was a gophone sim in Mozambique.
Does this mean that its unlocked if it is recognizing another sim, even though no confirmation of reception? I plan to try again with tmobile now and perhaps make sure I have wifi connection while doing so and leave it in for longer.
Thanks and please let me know if you have any thoughts.
what ROM you're on now?stock or costum one ? you also might consider a FULL phone wipe.because this might be caused by a difference between at&t apn or other Sim data and the other .check for that
I'm on stock 2.3 that the phone came with. Haven't messed with it at all.
So I assume you saying that if I want to switch to another sim, I should do full phone wipe then? so that the at&t apn doesn't confuse it?
IF it doesn't work with tmobile again, I will try taht, and I will also try to learn what an apn is.
Thanks for the help.
Might work or might not !!! backup all your data and apps first then use the shotgun method lol
But what I am sure of is that Nexus S phones are always unlocked and SIM free..

Why do I have no data network?

Ever since doing the htc unlocker last night, my mobile data speeds have been very slow at best. It would not even download anything at all, even though it says 4G on top. I am running stock and the only thing I have done to my phone is unlock bootloader via htcdev.com. can anyone confirm what the problem is or helps figure it out? Thanks!
Also, could it be Tmobiles network being down?
[EDIT] Now I have called T-Mobile and they have not done anything but filed a request to the engineering department. I still have a very low data connection. Can anyone tell me if the HTC unlocker tool messed up my phone?
Can't anyone put in some thoughts or tips or anything at all??
Call them...
Can someone please help. It shows the 4G icon, and the up arrow blinks a couple of times then they both blink together in about 2 second intervals. What does that mean?
I would really like to get my data back on.
After a long, hour conversation on the phone with a T-Mobile rep, they had done nothing to improve my data connection and filed a service request to the engineering department.
Can anyone tell me if the method I had used on my device to unlock my bootloader through htcdev.com messed up my data connection speeds? Has it done that to anyone else!?!?
Should I try to do a factory reset of my device? Please any help would be appreciated.

[Q] Getting unlocked Optus HTC One data working on O2 network.

Hello all,
Sorry to trouble you lovely folks but I have a bit of a problem.
I have an HTC One, purchased in Australia but it came as an unlocked handset and can accept any SIM. However, upon coming home to England and putting my O2 SIM into it, I have discovered that I can not get the data connection working, although standard calls work fine.
I have taken it to the shop to get the correct APN settings entered, tried various online permuations for APNs, and spoken with O2 tech support who eventually told me to do a full reset with the O2 SIM in the phone to get it to pick up the settings (it didn't).
Sooo, I was hoping that somebody else may be able to help me? Could it be to do with my software version or localisation? Will I need to somehow root the device and install the O2 HTC One Android ROM? Or will installing stock Android ROM akin to the HTC One Google Edition likely resolve my issues? Or is something else likely the cause of my frustration?
If anybody has a clue, a point in the right direction would be greatly appreciated. Should it be a case of needing a new ROM, then a link to the ROM download and a step by step on how to do it would be a life saver.
Thank you all in advance for your time.
:victory: :victory:
Anybody with any thoughts or advice? =)
Does anybody have any idea or suggestions on how to fix this?
Phone without data capability is epic fail -_-
Bump to see if anybody different may have an idea of how to fix no data connection problem =D
