I have a big problem which I hope all you Kaiser gurus can offer some advice:
I got my Kaiser two weeks ago, pop in my USA T-mobile sim card (GSM only) and it worked perfectly. I then went over to Taiwan and the device was put in Airplane mode for about 10 days. When I get back to the states, the phone no longer works; all other features of WM6 works except it the phone service.
It cannot find the t-mobile network regardless in auto or manual network selection mode. I tried the SIM card on my other phone and it works perfectly so that rules out the SIM card. I did a hard reset and it didn't cure the problem.
Question is, can the altitude or air cabin pressure somehow killed the phone portion of the unit?
What other diagnostic methods do you recommend?
Hmm I dont know if this is a good idea but emergency services like 911 should still work, even without service. And by that I mean without being signed up for service. So it might help to test 911, then hang up if it rings once. Just to see if your radio still works. If it does, then the issue might be that the phone is not configured correctly to T-mobile.
Now this is only true in the USA. I'm not sure where you are from. But given that the USA has just about the oldest infrastructure in any developed nation, I'm confident it can only be better where you are from.
No, 911 does not work. Does this mean my radio is fried? What can I do?
hmm... this sounds like a bad radio flash gone wrong... and not saying so!
I tried it with my friend's AT&T Sim and it worked perfectly. Does it mean it's the carrier's problem?
it means probably your phone got sim lock somehow. Just do hard spl and unlock it.
I'd get another T-Mobile sim card if your device works fine with an AT&T sim. I realize you said your T-Mobile sim works great in another phone, but that's the only thing that makes sense.
Ok I'll try that. Problem is, I have several other T-mobile lines and I tried those SIMS already and no cigar.
Anyone else can contribute any ideas? HTC is not support me because this is an import phone.

This is MISLEADING info !
Hard-SPL = CID unlock = ROM options
it does NOT unlock the SIM !!
hello all
i got the "no sevice" problem which looks like the same as Valleydog's.
i got my kaiser about 1 month, everything goes very well
today im in class and turn on the flight mode.
when i turn off the flight mode, it cant find the sevice any more,it tells "no sevice"
i cant dial any number including 911,86,110 etc......i swap my friends' cards they couldnt work,too
oh,just a nightmare to me, i flash the htc ship rom(which contains a radio),problem still...
could anybody help me, was it suddenly sim locked? possible?
Why such bad thing happens on me(good person)...........
KAIS130 with hspl v1,flashed many roms without problem,just this problem suddenly scares me
Sheng
This happened to me briefly the other day; running a stock T-Mobiles Vario III with NO rom flashing done to it.
I went to make a call and there was no service. The phone had been in my pocket for a while. I soft reset it and it worked after that, but took about 5 minutes before it picked up a signal... It's been fine since though.
This really sucks... I will head down to the T-mobile store and try out all their SIM cards until I find one that works.
The thing that puzzles me is that the other carrier's SIM (AT&T) works fine

Haha....im sure its got nothin to do with that....mebbe u dun pray enough
Here's an update...I tried 3 working SIMS cards in T-mobile store on my phone and it still does not get signal.
Very frustrated at this point.
My phone worked intermittently at one point but now it's dead again. What a piece of crap.
This is so annoying, and HTC have no answer regarding this issue.
It is clearly not a hardware fault!!!
I have the same problem & it is so frustrating you guys can't imagine.
I have always loved HTC machines, but I am thinking never again!

saper747 (andre),
Where are you located and what have you done to troubleshoot the problem so far?
Did you call T-Mobile to see if they have something configured wrong on their end? If the phone works with an AT&T sim, it would seem something on T-Mobile's side wasn't right.
There is nothing wrong as confirmed by T-mobile, the same SIM works on any other unlocked phone except my Kaiser

I am located in Israel I have tried 7 sim cards (2 -cellcom,3 -orange,1 -02 uk& 1-t-mobile ) non of them work on my Kaiser but they do in any other phone!!!
I have done soft resets & hard resets nothing helps.
it all started after I was trying to roam to another country and a day later my battery went dead, the next thing i new it wouldent register any network ,
Yes, I have read every other thread I could find.
Anyways, I bought a Samsung Captivate on Kijijii. I did test it before I bought it, and it picked up 5 bars, and more importantly, held the 5 bars.
Took it home, and ordered the unlock code, which took a few days to get through. In the meantime I upgraded the phone from 2.2 to 2.3.3. Everything seemed to be fine. Got the unlock code, put in my SIM card, put in the unlock code....everything worked perfectly. It didn't pick up a signal though at first, which is a problem with my carrier(I think). They make you go in and manually search and then register. Which I did. Well, for the longest time it wouldn't find the carrier. I have pretty crappy service, so I went outside, still nothing.....went to work and stood under a cell repeater which gives 5 strong bars to any other phone, and my Captivate would show my carrier, I would register, and it would get 1 bar, and then within 10 seconds, it would lose signal again. All while I was standing right beside the cell repeater.
Not only that, but for some reason it would turn on flight mode, and then when I would try to disable it, it would sit there for about 20 min doing nothing.
I went back to 2.2.....still did the same thing. Went to 2.3.3 again, still the same problem. Tried 3 different modems for my specific model phone, 1 of them would find the network instantly, register within 10 seconds, and then drop signal again and go into enabling flight mode, and being a general pain in the ass to turn off. I would actually have to reboot the phone to be able to search for networks again.
The phone came from Rogers, so I put in my brothers Rogers SIM card, and it instantly found the network, registered and gave me 2 bars without me having to do anything. Except then it began dropping signal, getting signal back...dropping it, getting it back. It is winter here right now, and we do have spotty service, but I have Samsung Fascinate that holds at least 1 bar consistently. Not sure if the antenna strength is better. From what I understand they are more or less the same.
I swapped out my SIM card into a different unlocked phone and got service instantly, and then put another different SIM card into the Captivate, and it had the same problem.
I'm pretty much out of options. I'll try tomorrow to see if I can hold a Rogers signal better, which it hopefully can because I'm thinking of selling it.
But I'm inclined to believe that it might be a software problem. Problem is I have no idea what to do in order to fix it.
Any help would be greatly appreciated. Thanks!
Played around with it a bit more. On 2.3.3 with the KH3 modem installed, it will find the network, then try to connect for 10 min, where it will then say 'unable to connect, please try later.'
Then after clicking again, it will say 'unable to connect, select automatic registration' and then sit there for another 5 min. When it finally comes back, I will click on 'select automatically' and it will say after a couple min, 'registered on network', but won't get signal.
All of this I do with 5 bars service. Or in an area with 5 bars service.
Also, the flight mode constantly comes on, and disables 'mobile networks'....so I can't access it. And its a bit weird that it would do that, since any other android phone that I've had, when I lost service, it would constantly try to connect, not go into flight mode and refuse to come out.
Would it help to install a custom ROM on it? I'm going to try going back to 2.2 and test some more stuff. Problem is the small amount of time I spent with 2.2 last night, the phone would crash everytime I tried searching for networks.
After playing around with it even more, I'm convinced that it says 'error while searching for networks' because the phone constantly jumps back into flight mode.
Even when it does get a signal and registers, the phone jumps back into flight mode within a couple seconds, and bang the signal is gone.
Are you flashing with the sim card in the phone? Or if you are flashing through cwm are you leaving the usb cable plugged in?

I flashed with Odin, WITH the SIM card in the phone. I never bothered to take it out. Would it make a difference?
I actually just flashed back to 2.2 with the SIM card in the phone. It found the network, registered on the network, but then dropped signal and activated flight mode again.
Odin flash goes like this. Put phone into download mode, plug phone into USB, open Odin, put 2.2 file into 'phone' section, make sure re-partition isn't checked, click start, and it does everything it should do. Phone restarts running 2.2.
No open ODIN FIRST!!! And then plug in phone... know your stuff before you give false info.

After flashing back to 2.3.3 without the SIM card in the phone, I still get the same problem. But the phone doesn't seem to constantly be going back into flight mode.
Does the modem file change if you go back to 2.2 and back up to 2.3.3? I might have flashed the wrong modem or something.

I'm not quite sure what you mean. I've done it both ways, and each time the flash has been successful.
I should mention that baseband version on my status menu says 'I896UXKH2.'
And I'm running 2.3.3.
So I'm not sure if the modem changes when you go back to 2.2. I forgot to check that.
I thought you were suppose to put it in the pda slot not the phone??

I did actually put it into the PDA slot. Sorry.
Anyways, rooted and installed CM7, installed the KC1 radio, which SHOULD work in Canada on the 850mhz band, and when I search for networks, the only network it finds is Can Rogers Wireless Inc. Up till now it found MTS as well, which is the network I want to use.
I have an MTS(working SIM card) inside the phone. Just bizarre. Could the unlock code not have worked correctly?
Just completely bizarre. I couldn't get any modem to even recognize and find my network of choice, MTS.
So I went back to exactly how the found was when I bought it. Stock 2.2. Going to find out if even a Rogers SIM card will work in it.
There could be two possible things:
1. Unlock code would had messed up.
2. Corrupt IMEI number! Check IMEI number on the box of your phone or below battery and compare with that of the phone (*#06# or settings)...

The IMEI number on the status menu on the phone is identical to the phone under the battery.
So that leaves the unlock code. The guy who gave it to me, cellunlocker.net gave me instructions for locking it to a specific carrier. I tried that with MTS, and it doesn't work. Basically you punch in a code in the dialer, put in the MCC/MNC code, put in the network lock code, and lock it for that carrier. It said it worked successfully, so I have no idea what else went wrong.
The instructions I mentioned above he gave me after I told him the original method didn't work. That method being putting in non-accepted SIM card, and the box pops up asking for network unlock code. I punched the code in he gave me, and it said unlock successful.
Anything else I should do?
I have the similar problem on any 2.1~2.3 stock firmware which I have tried.
I'm using Tmobile now, and the IMEI is correct.
But I only receive 1 bar or no bar signals.

So you unlocked your phone as well? Perhaps the bands are wrong? I know T-mobile uses a different band than other US providers.
In my case, the Captivate uses the 850/1900 bands, which is what Rogers and MTS use.
MTS being the carrier I want to use it on.

I ordered my unlock code from cellunlock.net and it didn't take. I used the Galaxy S Unlock app and it worked fine. When you enter *#7465625# it does show the network lock as off right?

Didn't take as in it said it cannot unlock? Because when I put in the code from cellunlock it said unlock successful.
But I didn't know you could check with that code. I'll do that later. Thanks.
So apparently I had locked the phone to MTS. Put in a Fido SIM card to try something different, and it said enter network unlock code. Entered the unlock code I got, and it said unlock successful.
Now when I type in *#7465625# it says 'off' under all the headings, just like my Fascinate says.
It still holds signal, loses signal though with Fido. I have no idea if that is a problem or what is going on. It'll get 2 bars, or about -99dbm, 5asu, and then suddenly drop it. Get it back again....drop it after 10 seconds.
Apparently flight mode is going on, going off, going on, going off....which is apparently why it loses signal, and gets it back again.
I bought a c510e as they call it here in China. Got the s-off at the local mobile repair shop. Then I "updated" the ROM to a stock O2rom.exe so I could get facebook, and Android market apps and get rid of all the Chinese apps that I cant use anyway. Phone starts up fine, but I get a message (In Chinese) about my sim card, now I don't have a carrier. It shows 4bars,and that I'm using a CMCC sim card but no connection. WIFI works, but I can't make calls. So I figure maybe the O2 ROM was sim locked to the O2 carrier? I do a restore back to the original China ROM but same thing. I get an error message about the sim card, shows 4 bars and that I'm on CMCC, but no signal connection. Did the "update" screw up the radio?
I'm thinking see if I can update back to a full China ROM and see if that helps.
Any thoughts on what went pear shaped?
Luckily I leave china tomorrow so maybe once I get a new sim card the error message will be in English and I will have a better understanding of what the problem is..
Cheers
Well not sure what was wrong, I flashed the phone with the XTC-clip and re-rooted and all is good.
this is an unknown area.....i didn't have any issues with roms, went from British to Chinese, purely for space, flashed 5 times, no problems.
glad you got it working mind!
Any base rom that is from a network ie o2 is always locked to there network which means you have to ensure the cid is set to an unlocked status, which is what the xtc clip would of done, hence why it would be an unknown area, see big bear even though i got shut of mine still try an lend a hand
Good man! Glad your sticking around

I have an AT&T 920 that I bought 2nd hand and got unlocked.
I've unlocked a half dozen WPs, all originally Canadian phones, this was my first U.S. carrier phone. I went through the same procedure, non-carrier SIM, enter code, etc. And it appeared to have worked, but I tried two different SIMs and the phone wouldn't register with the network.
OK, so maybe some more fiddling is in order..
I then went through the procedure using the NCS to re-brand the phone to Rogers RM-820.
Once the Rogers ROM was installed, I had access to the diagnostics, including checking the status of the SIM unlock. Which showed as still locked. So I entered the unlock code I had, and now the phone shows as SIM unlocked.
I've also tried a different SIM tray for a 920 with no luck.
All of the above still did not solve the problem.
The phone "sees" the available networks. (Fido, Telus, Bell) But it won't register with them.
As the phone has a cracked screen, and I have a replacement for it, and I'm going to be opening it up, is there something physical I can check on the phone while I'm in there?
Is there anything in the diagnostics I should be looking for?
I bought my M8 from a guy a year ago and it wouldn't receive any data(only worked on wifi), so i took it to Sprint and the guy said it was because the phone was rooted (i see a prompt for #SuperSU and the guy i got it from was recently returning home from asia somewhere where he used the phone) he couldn't touch it. found another sprint who took it overnight and wahlah, it was fixed, but he didnt tell me what he did to fix it because the phone is still rooted, or atleast still has the prompts telling me the SU bianary needs to be upgraded
i broke the phones charging port a while back, and switch to iphone and now am switching back to m8 now that i fixed it but im on tmobile now, and cant take it back to sprint to have the guy refix it.
i put the working tmobile SiM into the port and the phone still says Sprint as my service provider but also has the error message 'invalid sim card 4G services are unavailable' but wont let me click on the error. i took it to tmobile and they couldn't do anything with it because the 'access point names' field is greyed out and wont let you click on it
Does anyone know what sprint may have done to get around that or what is causing the SIM not to be recognized. The guy i got it from originally had it on TMobile, til i switched it back to sprint, so it is an unlocked phone, it just has something deeper going on w the point names i guess?
Post ur getvar all.. s-off or s-on. If phone is still rooted then try the SHORTCUT MASTER and search for apn settings and edit it ... the apn settings are greyd out as the phone is locked to sprint (showing invalid sim) post hboot screenshot .
