HTC S620 radio problem - HTC Excalibur

Hi all.
Picked up an S620 at Dubai Duty Free and it cannot hold onto the radio signal here in UK. I am in a 5 bar signal area and the HTC locks into the signal at 3-5 bars strength for between a few seconds and maybe 1 hour then searches and finally freezes requiring battery removal to re-start.
Have cold booted device several times - no better. Have set network to manual as per another post here.
Appreciate any advice.

Operator locked?
Sim locked?

No and no, at least I don't think so.
Handset was purchased SIM free so I assume all unlocked. I have tried 3 different UK SIM cards in it with similar result ie picks up signal and is usable for between 1 and 45 mins - I can make and receive calls at this time - then loses signal and searches displaying variously 'searching', 'phone off', 'T-Mobile' (or operator name). All this happens over a period of up to around 45 minutes before the unit freezes completely and the battery needs to be removed to allow re-boot..
I'm fairly sure the handset is broken but, since it will have to be returned to Dubai and I am in UK, I wanted to try any options available.
Everything else works OK.
Appreciate your help.

problem with HTC tytn hermes 200

I bought an unlocked HTC TYTN Hermes 200 from a private party. He lives about 40 miles away from where I live and he used it with T-Mobile in California (I live in California also). Before I bought it, I tried it out (while I was in the same city that he lives in) with my T-Mobile SIM and made a phone call and the reception was clear.
Since I got home, I've had problems in 2 places (home and work which are about 5 miles apart) where I have 1 bar of reception and if someone tries calling me, it doesn't even show an incoming call on my phone, it goes straight to voice mail and if I try to call someone, it doesn't ring even once, it just says call ended. When I am at other places, I usually get decent reception (but not always).
I have tried flashing all of the recent radio firmware but nothing has made a difference. I also tried inserting another T-Mobile SIM and had the same problem. My previous phone (unlocked Treo 650) had really weak reception in those same areas but not this bad. The phone is not warrantied, according to HTC. I have made sure all my network settings are correct. It's running Windows Mobile 6. I think it might be a problem where the HTC antenna doesn't pick up a signal as well as weak T-Mobile reception.
Any ideas of what I can do about my problem ?
I think you're in the wrong forum, this is for Trinity not tytn, maibe there they will help you.

[Q] 2G Signal only, enabling 3G drops signal totally.

Hi everyone,
I have a generic unlocked desire 2.2, unrooted, as standard as they come and connected to Orange.
When I run on GSM only mode in network settings my phone is fine...
BUT..
Enable WCDMA or WCDMA auto mode.... and it will connect to 3G for about 10/20 secs then drop the whole lot, "emergency calls only" is all I can get.
I live in town with full 3G,and have tried at my girlfriends 100 miles away too. This has been going on for about 3 weeks, and so far I have.......
Hard reset a couple of times....
Had a new SIM from Orange...
Tried a different SIM (O2) in my phone - which works perfectly, sat browsing on H for about half an hour or more with no problem.
Tried my SIM in a different phone (Touch Pro) - works perfectly as well! 3G and browsing internet all fine.
So - Orange say its the handset.... and I'm not sure their 2nd level tech really exist, cos I've never got to speak to them or had the promised callback!
and HTC reckon its a network issue.
I can see both sides, but that doesnt help when your stuck in the middle with sloooooow internet.
The only other thing I can think is that Orange dont like the fact I'm on unlimited data and using it, I hit about 900mb a month normally and 2Gb in Nov when my home broadband died for about a week. perhaps they have blocked my handset from 3G? If so they havent told me though! I have one of the panther tariffs from mid last year which were "unlimited".
Any suggestions would be very appreciated!
Thanks in advance
Chris
Sounds strange indeed......
Theoreticly speaking, they could have placed some sort of a limit on your account to reduce the load on their network, but It'll be hard to prove. (Maybe you know someone who works there???)
You can look for your plan's contract (or ask them to fax it to you) - maybe it states the minimal speed of connection....
Threaten to disconnect if your speed does not improve..... Realy can't think of anything else.
EDIT:
Try this http://forum.xda-developers.com/showpost.php?p=10865272&postcount=5
Thanks,
I have tried all the options in that menu with no success.
Eventually last night I got orange 2nd level tech who was equally confused and could only suggest a radio version conflict with my handset and network.
Anyway they gave me a fault code which CPW (I purchased from mobiles.co.uk) looked at and glazed over.
I have called HTC direct now and they are having it in for warranty repair. 10 days with my old touch pro... how bad can i be?
Wouldnt surprise me if they send it back NFF........
fingers crossed!
EDIT: THE TOUCH PRO IS AWFUL!

Vodafone Sure Signal

I have a Vodafone Sure Signal femtocell device, which connects to my broadband and provides a localised 3G signal in my house, as network reception here is poor.
I have 2 other phones connected to the SS just fine, but the One X is intermittently losing the connection and needs a reboot to re-connect. There have been some other posts on the Vodafone UK forums from folks with a One X, not many but enough to make me wonder if there's a more common problem.
Does anyone else here have a Sure Signal, and if so, are you having any problems with it?
I don't personally have it but my friend does and he is getting drops constantly he is not best pleased as he had yellow spot issue aswell aha i think he's going to thro the OX off the wall shortly. He has phoned regarding this and got nowhere
Thanks for the reply. VF have contacted me after I posted on their eforums, I've raised a ticket and they're investigating. I'll report back if anything improves.
VF UK are really pushing the One X, so if there is a problem, I imagine they'll want to get it fixed.
do the vodafone handsets have vodafone firmware? i have a factory unlocked non branded unit I'm using on vodafone with SS and hab=ve had zero problems!
Thanks for the reply. I got mine from dialaphone and it's pure stock WWE. It's working now, but still a little flakey. If it loses connection to the SS, I turn airplane mode off and on again and it works again (quicker than a reboot).
Most of the One X users with problems on the VF forum have their old number on a new sim card, which apparently can cause the Sure Signal to bug out a bit until the new sim is registered. Mine is a brand new number though. It's lasting a day or so before I have any issues.
The SS has always been a little on the flakey side, though, I need to reset it every so often - but that's been weeks or months apart rather than days.
I have one of the older models with 4 lights, not sure if that makes a difference.
Half wondering if it's the phone not the SS, but will see how it goes for the next few days.
I have had very poor suresignal performance...and have swapped out one phone already after speaking to HTC.
But have found that by turning off WIFI, it seems to be a lot happier, and the replacement phone acts just the same as the first (sim free from CPW)
But without WIFI, all data comes out of your data plan, and not from your broadband even thought the SS uses the broadband connection.
I never got to the bottom of my sure signal problems with this phone until I installed cyanogenmod.
However I recently installed sense 5 and my phone would again not connect to my sure signal. I have gone back to cyanogenmod and the problem still exisits.
Can someone who uses a sure signal please tell me which radio you are using by going to settings, about phone, baseband version
Many thanks

Loss of signal, no auto reconnect.

I am having an issue on my One X (unbranded and unlocked) with the signal vanishing and not reconnecting unless I force it. I was wondering whether it effects all networks or just networks that use more than one carrier. Three has its own 3G network but it uses Orange 2G signal. I also saw a thread with the same issue on T-Mobile / Orange which is also dual carrier.
I am wondering whether it is the switch between these networks which is causing it to lose signal and not reconnect.
I have had several instances where my signal has an R next to it as if it is roaming, this would be when it is connected to the Orange 2G network, I never had this problem on my Desire HD or Sensation.
Does anyone know of any issues on Vodafone or O2 regarding signal loss or is it just networks which use multiple carriers.
My One X is stock and bootloader has not been unlocked.
Thoughts?

Are you still on the 126 SW?
As your unbranded then you should be able to get the 128 update.
With 126, my Three handset recieve level was about -88 to 91dbm.
With 128 its now at -75dbm in the same location.
Most, if not all of the roam to Orange has now been disabled, remaining where there is no Three signal at all.

No I have upgraded to 1.28, unfortunately I am still in an area where it does switch to Orange 2G signal.
It seems to hang on to 3G until I have virtually no signal, then goes to no signal and doesn't reconnect unless I force it. It seems to mostly happen when I put the phone away on my pocket so I dont notice I have no signal until I check my phone.
I lost signal today and to test the reconnect I left the screen on and I drove about 20 miles through large-ish towns and it didn't reconnect once, had to force it when I got home.
Not sure if this effects single carrier networks, O2 or Vodafone?

Have you had the same issue with any other handset?
Are you a new customer to Three and this is the first you have seen of this?
Reason I ask is when I was thinking of going to Three for my main phone, I tested with a handset I just used for tethering off the one plan.
I drove out of town to an area where I guessed there would be no Three coverage.
The signal hung on for ages but when it dropped I made a note of where it dropped. After a few moments the handset went over to Orange 2g. I then drove back home. I must of drove at least 5 miles past the point I noted earlier before the Orange signal itself dropped and had to force the handset to Three myself.
This sounds similar to your issue and was with a Desire S….but you say you didnt have this with previous handsets. All very strange
Steve
I've had a Desire HD and a Sensation both on Three and never had issue on either of these.
There must be something different about the way the One X handles the switch of signal, or maybe it's just faulty.
Might try some other SIM's from other networks, if that doesn't work I'll get a replacement.

I'm on three and it never seems to switch to gsm just looses signal all together and takes ages to reconnect once I move location. this is a proper pain I've had the phone replaced three times changed sim still not got better I'm thinking its the radio version on this phone or some software related issue.
If you're phone is from Three you won't get the update until Three release it.
I did see on another thread that Three won't be releasing 1.28 as HTC are currently working on the next update. Don't know how true that is.
My phone is unbranded and unlocked to any network, which is why I got the update.
Think I'm going to get a replacement and see if that's any better, hope it's not a general issue with the one X having lower signal.

If you dial *#*#4636#*#* on your phone and select phone info you can select GSM only which is 2G, this really improves signal but because it's 2G you are stuck on really slow data speeds.
If that is the case and you've had 3 replacements, maybe it's worth holding out for the next update to see if that fixes the problem.
I'm a little uneasy about returning it for a replacement as I don't have any other problems with it (bad screen seal, banding on display or yellow display) I may end up with more problems with a replacement.

Is any chance change three rom on factory rom?
I had similar issues to what you are describing with yours on my original unlocked/unbranded HOX on T-Mobile. I had issues on top of the ones you mentioned where it was also saying I had a signal and had appeared to lock up and would just drop the mobile network and say at the bottomg of the screen "preparing sim".
Most the time I was stuck with putting it in and out of airplane mode to make calls, only for them to drop or fail all together.
This was on both 1.26 and 1.28 FW. In the end I took mine back and swapped it and the replacement has been perfect since. so it was without doubt a hardware fault in my case!
Good luck solving your problem, but I would suggest taking it back and getting a straight swap.

You can't change you ROM unless you unlock the Bootloader at HTCDev and this will void your warranty with HTC.
Three will release an update eventually, and 1.28 is no better signal wise for me than 1.26 was!!

Interesting, I too had the Preparing Sim message until I got a new SIM from Three, this seemed to fix this message but I am still having Signal Problems.
I think I'll follow your lead and go for a replacement, I have to use Airplane mode to force the signal to reconnect as well.
Thanks
I can confirm I have these problems. I'm on three but the phone was from Dialaphone and with orange but is unlocked. I have exactly the same problems as those been described. This is a very irritating problem that makes me miss calls and texts in my poor 3 signal area.

I think you're best off to return it for a replacement, that's what i'm going to do. Hopefully that will fix my problem and not create any more!!
I have the same issue on my device. On my 2nd replacement and its still the same.
No problems with my iPhone 4S.
Hopefully a radio update will sort this out.

I think it might depend on location, in some areas the 2G signal (Three use Orange network for 2G) has been turned off. In my Area (South West England) I still have access to the 2G GSM Signal.
Obviously Three save a lot of money from turning off GSM and not paying Orange to use their network.

[Q] AT&T Sim on T-Mobile S4 - Drops Connection

I bought a T-Mobile S4 and unlocked it thanks to this website. I also did request the unlock code (which I do not have).
Anyways, phone seems to work fine but I notice occasionally when I wake the phone up I have the no signal icon and it takes 5 - 30 seconds for it to reconnect to an AT&T network. It seems to happen a couple of times per hour. Any ideas?
