Phone Off on Power On, outgoing call problems, etc.

I am using the latest HTC ROM in the UK with Radio v. 1.03.03.10. When I restart the unit in the morning after switching the power off overnight the phone is off enough times to be a nuisance if I do not notice it. Occasionally it switches into flight mode when the unit is on as well, but this seems to be happening less frequently. I also sometimes have difficulty making outgoing calls, ie the call ends before even getting connected, and redialling will not work until I switch the phone off and back on again. Is anyone else having these problems? Is this an issue with the radio ROM? I have read about the difficulties with the latest Radio ROM upgrades on the forum, and if a Radio ROM upgrade would solve the problem I would appreciate some advice on the best one to go with for use primarily in Europe, with occasional travel to the US and Japan.

Hi, Sorry to hear about your issues, I and a couple others here have or had the problem with the phone being off/flightmode after turning it off, then back on.
Theres a another post about this somewhere..I was just too lazy to find it before I posted, and last I checked a true fix hadn't been found.
If I am correct it shouldn't occur if you only do a softreset, and if you look at your signal bars when you shut it off, it looks like it turns the phone/radio off during the shutdown process...that is normal I'm pretty sure, cause even when it worked correctly it still shut the phone off before a power off, I think the issue is related to the startup process and it isn't correctly turning it back on.
I have had it work fine for the longest, and then when I installed some software it quit, after the fresh installation of software it has worked again, also I notice if I power off the phone while its charging and then power it back on, it always works correctly.
I haven't had any actual incall/call issues myself I can't say if a Radio upgrade would help with that, but I don't suspect a radio only upgrade would help with the flight mode being on after a power down, but I am far from being positive, I think its installed software/ROM related, sorry I can't be of some real help, I'm dealing with it myself..its aggrivating to me, I have forgotten to turn flightmode off and missed calls for half a day untill I looked and noticed.

Start the improvement way by upgrading the Radio ROM
http://wiki.xda-developers.com/index.php?pagename=Hermes_ExtractedRadioRoms
Here you can find the 1.20 ROM, extracted from JASJAM ROM. Try to install it on your device.
Tell me about this.

Thanks for the feedback and the suggestions. Most helpful.

yes - i get that too - constantly (on a t-mob vario) - i get bumped off the network at least 5-10 times a day and it takes me anywhere between and 10 minutes to get back on. i also get bumped off systematically every night (i am always off when i get up).
calls too are a disaster - an average, it takes me 3 or 4 tries to complete a call when i have full network. (sometimes as much as 10-15 tries)
took my sim and put it into a magician and all went away, so *suppose* it could be a 3g thing, but i am really not convinced because the hermes does have a 2g radio as well (so it should fall back onto 2g whenever 3g fails...)

Not a Fix but a Working Solution
I started having the issue of the radio being off on startup a few weeks ago.
So I invested($10) in a copy of SK Softwares Scheduling Manager SKScheMa.
http://s-k-tools.com/index.html?skschema/m_skschema.html
This has a powerful scripting language and one of the script commands is "GPRS on"
I created a shortcut in the startup folder to a GPRS On script. and since then I have had no more problems.

i´ve the some problem, what do you do for no more problems ?¿?¿
thanks

Thanks for this. I will give it a try. Do you know by any chance if this also provides a way to have the phone ring through the speaker when it is connected to a Bluetooth headset?

>Thanks for this. I will give it a try. Do you know by any chance if this also provides a way to have the phone ring through the speaker when it is connected to a Bluetooth headset?<
If you are refering to SKSchema, then this should be possible. You can create a script that runs when a call is received.
The script can then instruct the phone to play a sound file.

We turned off the UMTS service and reverted back to GSM and that seems to have solved the issue.
Hope that helps.
Cheers,
J.

Just a slight update to maybe help find the cause, I had created a backup with spb before the problem occurred (minus pim data and emails not sure if it mattered) and after having the problem arise again and a few other issues, I decided to hard reset and try out the backup I made.
After installing my backup the problem was gone, and then I got bored the other day and installed some software, and I think removed some, and I had it happen once again after I had ran memmaid 1.72 and rebooted.
I don't know if it the software installaions that are causing it..but one thing that has been a constant is the memmaid, and it could even be my fault.
Is anyone having this happen to a basically oem device?

Well, I can't exacly tell why but I get the same feeling about extra software.
After a hardreset or ROM upgrate (now Cing 1.34/radio 1.16) everything's fine. I deactivate ActiveSync and install some extra software (PocketZenPhone, Total Commander, Regedit, TomTom). After a few days still everything's fine. So I install some other software (SPB PocketPlus, Jetware, a today- and phoneskin) and still everything's fine for a few days. But then on a (not so) fine day: it hangs! The phone doesn't react or TomTom is hanging on the startup screen or the whole device is freezing. Why? I don't know, softreset and everythings fine for a few days.
I notices a few situations while it happened: first when I connected the carpower adapter and second a few times while receiving a phonecall (in my carkit and on poweroff).
Uninstalling everything doesn't seem to do the trick: it still hangs now and then. Also I dont have the patience to hardreset and use my device clean, without extra programs for a few weeks. But I guess in that case everything would be ok (?). But a device without the extra's has no use to me...
My feeling is that the installing the extra's causes a instability in the registry or elsewhere. I also have the feeling that the hardware causes certain instability: the gliding keyboard, the screen (alignmentproblems), the buttons, the SD-card, the network cards, bluetooth... (I had my device in repair with HCT because of the too easy gliding keyboard, the stylus, and the instability with TomTom, but those problems are solverd for now, exept for TomTom). So much hardware, so much software, all in one small device...

A small addition to my previous post: I think another possible cause for instability are the famous memoryleaks. Starting and stopping programs in my opinion never clears the whole memory, in spite of "real" programstoppers like SPB PocketPlus. After working a few days this could cause a freeze (?)

HD2 freezes after answering a call

Has anyone suffered this problem? Phone rings, I pick up the call, the screen shows connected and starts the call timer but you cant hear anyone the other end. hang up the call and the phone freezes with only a soft reset (taking battery out) works. I have a T-Mobile contract handset and was running the 1.43 rom. I thought maybe flashing to another rom might help so tried the 1.48 update but still having problems. I have hard reset and installed no software but still have the problem. Any ideas guys.....
Since I cant see this problem on the forum I'm guessing its hardware related. I guess I'm going to have to find the original T-Mobile rom and flash it back before returning.

hey, I had the same problem and had even started a thread today. I went for broke and did a hard reset and this has solved it. Back up all your info and hard reset and pronto good to go!!

I wish it was that easy for me. I have hard reset 3 times, the last time I didnt install any software just in case one of my apps was causing the problem.
Everything seemed fine for a day or so then someone called me and it crashed again.

it has happen to me 2 times in one month, first time i was listening some musique some one call and as soon the call ended it Freeze.
Another time the phone was on stand by and some one call, and could not answer the phone just freeze.
Why why why Is HTC brilliant

I have the same problem with my WWE HD2. It seems to be linked to music playback off a slow microSD card. I used to get the bug with a Class 2 16GB card if I happened to be listening to music while I received the phone. After tha call ended the playback would resume normally but after a while it would start to stutter (reminds me of a similar bug in the original Diamond, infact) and eventually stop. After that, the phone would just stop responding to any inputs.
After popping in a Class 6 8GB card the issue is gone.

Interesting you mention listening to music but for me the crash happens when the phone is in standby, caller id shows, then I hit the answer button and the call timer starts but I cant hear the caller. From then on, I can hang up and then a complete freeze. I wasnt listening to any music, the ring tone is on the phones memory not sd card, so not sure about the sd card connection. After my last HR I didnt install any software except resco file explorer and microsoft my phone. I still get a crash.
I was going to return the phone back to tmobile for repair but it sounds like its software related rather than hardware.

Flash,
Have a look at this thread...http://forum.xda-developers.com/showthread.php?t=468284 , act on it and see if it helps. Phone lockup in the way you described happened to me a couple of times when I first had the phone; no problems now.

Me too. i didn't had this problem with Rom 1.43

Found solution guys! It was me not closing down the radio before pulling the headset out. I have not experienced the issue anymore.

What do you mean by "not closing down the radio" ?
Daniel

Sorry, I forgot the FM bit. In the past I used to listen to the FM Radio and pull the headphones out and the handset I thought automatically closed the FM app down. Any calls recieved on the handset after this would hang the HD2 after picking up the call. Up until the phone rang the HD2 would perform as normal, it was just an incomming call that triggered a crash. You could even make an outgoing call without a problem!
Now I close the FM app (by using the standbye icon on the app) first, then pull the headphones out. Not had the issue again.

Not solved for us that this happens to everytime... i can reset myphone and try to call right after the reset and it still happens.... I cant make a call or recieve a call at all lol

I had the same problem with radio rom 2.06.50.04 and 2.07.50.27 and miri's rom 6.5 v4.0.
Flashing to dutty's HG v0.8 rom with radio rom 2.07.50.27 solved it.

I had the problem with Dutty's v.06 and now have it with RoMEoS Rom....Don't think it is the Rom, and thought it was an app I isntalled until the OP said that he still had the problem with it even with no apps installed...

You might wanna try some different radio roms. Not really sure if it helps, but I guess the radio rom deals with calls etc.

Hmmm alright I will try that, I didn't think the radio rom's would freeze the phone...but I will try that as soon as I can get home.

Can't make calls & won't hang up (HD2/leo)

Can anyone help??
I've had my leo for a while now and I love the phone with one major exception.....
Sometimes when I call a contact nothing happens then after an eternity, 2minutes, the call is placed. I have good network connection and have tried it with and without 3G.
When this error is present I also get a problem whereby I can't hang up.
This seems to be a software problem. I'm on the T-mobile network in the UK. Does anyone else have the same problem?
I couldn't find anything on the forums. I've tried stripping programs/software off and have tried both hard and soft resets. The problem appeared to go away after a hard reset but then appear again weeks later for no apparent reason.
I have the original ROM version (1.43.110.2) and no significant mod's apart from Cookie home screen tabs and a few simple registry tweaks.
Any help guys, I'm contemplating taking the phone back but will I just end up with a reconditioned model? Mine's in mint condition and I don't want to end up with some banged up phone.

Hi, Did the phone work before the reg tweaks and software installation? A new T-Mobile UK ROM was published on the 15th, it might be an idea for you to flash your phone, test it then tweak, if it doesn't work after you flash it then speak to T-Mobile. If it workls after you flash it but not after you tweak then there's your problem Here is the link to HTC's UK web site with the download. I'd guess that T-Mobile will have a link on their support site for it too, somewhere: http://www.htc.com/uk/SupportDownloadList.aspx?p_id=297&act=sd&cat=2.
Hope this helps.

Mine does the same thing. Also mine also freezes when I get incoming calls. After I talk to the other person, I can't hang up. It's frozen. I have to hit the reset button on the back or take out the batter. I have two HD2's T-Mobile US Versions on release day.
I did do some HD2 tweaks to turn on the LED when I get messages though.
I'm going to reset both devices and see what happens. Maybe the old softwares don't work on the HD2 even though it's for WinMo 6.5.
I really hope it work, because I hate to return the unit. It's a beautiful hardware.

Thanks CMMY, I'll try installing the new ROM as soon as I get a chance.
I didn't have the problem before installing software/tweaks; but then again it was only probably a couple of days before I played around with it. After I did a hard reset and reinstalled some software it was working fine for at least a week before the problem re-occured, which seemed quite strange. Today the phone is working fine but will undoubtedly return, the fault seems entirely intermittent.
Daily driver: I also have the same problem when recieving calls. I'll let you know how I get on.

Same problem here, my phone is 3 days old and I have to remove the battery to end most calls, did a master reset and thought that fixed it. Couple hours later it was back at it. I'm using a tmobile hd2. This seems to be a very common problem, hope they come out with a patch soon..

Same problem here, hope it gets fixed someday

all the same..

I have this issue across diffrent roms, soft reboot does not fix it. just fixes itself after a while

Hi
Did you find a solution to this problem?
I'm using GSM HD2 Europe.
This problem start occurring after a while when I was using 29 Aug Energy rom.
After a reset the phone work ok for few hours.
When to problem start, the send physical button does not work.
if I want to make a call I must use the "phone" from the start menu.
When I try to end the call, the phone software stop responding, but the operation system keeps working.
In order to end the call I must remove the battery.
I when back to the original rom 1.66 from HTC site.
the problem still exist but less frequently.
(by the way the original rom work much slower then the energy custom rom.)
I’m wasting so much time on this phone, and I’m on the verge of giving up .
I will be happy to get some help.
Thanks

If you do not have BsB tweaks, but used tweak #44 in "Leo's tips and tweaks", this can cause problems for some.

can't hangup
I found the reason for this problem. (at least for the specific problem I had)
I'm using resco keyboard.
if I leave the Caps lock on after using the keyboard, then the "Send" HW button does not work, and you can't hangup calls.
by opening the keyboard again and releasing the caps lock the all work fine again.

I've also had this problem... Made me consider selling this otherwise great HD2, sometimes even running it over with a car
When I want to make a call, phone just won't dial - it freezes, but everything else works fine (only "phone app" freezes). So, I give up the call. Few minutes later, it unfreezes, and phone starts calling. Usually, from my pocket. Also, after a call, I can't hang up. I often ended up with removing the battery.
I tried everything...
Restarting the phone makes everything ok, but only for a few minutes.
Installing different app, tweaks, etc - nothing.
Removing everything and returning the phone to factory settings - nothing.
Then, I remembered to disable Sense. That was it. I have used the phone without Sense for months, and it didn't happen. Not even ONCE!
Can anybody here do anything with this?
I still want to use Sense because it looks awsome, way better than Windows interface...

You could try a custom rom. I have been using Dutty's latest and greatest without any of the problems you're describing.

Date & Time not updating!

Hey all. For some reason my phone will not update the time and date automatically! I tried doing a reset but that didn't work. Also, the weather displayed "My Location" for a few hours after the reset until it suddenly clicked. However, the fact my date and time are not auto updating means I can't use Live Messenger or Marketplace which is frustrating. I can use the internet fine, I don't know why this is happening :S
Can anyone help?

What rom are you using? i seem to have this same problem, it dosnt update the date and time, i have to do it manually, its very bothersome.
i am using Duttys HG evo v2.7 wwe, i am considering changing it because of this problem, love the rom but this is a problem.
maybe Duttys HG v 3 will resolve this?

I'm using the standard one, 1.73 I think. Its kinda weird, never had this problem before.

When did it start to occur?
I noticed that on my HD 1 i had problems updating time and gps position when i was in colorado for some reason, the gps on my truck was fine, but the phone didint quite get the data needed. I was up high and in mountains, what about you?

Well I'm in the UK. I got my phone back from repair due to slow network connections. Now that's fixed (super fast), the date and time don't update lol. Happened since I got the phone back (yesterday)

Well not really sure about this one, being that i dont really know if the repaired a hardware of software component.
But anyways, try going to settings, then location and at the bottom there should be and option that says SYNC TIME WITH GPS, enable that, reboot.
Its worth a shot, if not just disable it if you choose too. good luck

I don't have anything that says "Sync time with GPS" :S

FIXED!
Ok, I figured out how to fix this problem. If you have windows mobile device center, start a sync between the phone and the PC. I noticed everything automatically updated (Date, Time, Weather) and everything is fine now, i can access messenger and marketplace and the SMS is ok. I am very pleased and hope this can help a few other people too!

My Omnia 7 keeps loosing it's 3G connection

My Omnia 7 keeps loosing it's 3G connection. To restore it I have to restart the phone. T-Mobile say that this happens from time to time, but it's happening every day now. It's annoying as it stops my push email from being up to date, and of course prevents the use of any internet based services until the phone is restarted.
Has anyone else noticed their phone has switching to GSM?

Had mine for 6 days.Been fine up until today,then I had the same problem.Only the once so far.

Confirm loosing 3G
Confirm loosing 3G connection, and also have phone call failures.
Factory reset did not solve the problem.
Bring it back to shop
Blackstone is back now!

At first this was occasional with my phone, then more frequent, and it's all the time. If I want to use the Internet I have to restart the phone. My house is covered by full HSPA, but the only way to get it is to take the battery out while the phone is switched on. I can sometimes get 3G by a simple restart, which I lasts about 40 minutes.
I like the phone, so I'm going to hold out for a software update. All it needs to do is check available networks and I think that, if this is a wide spread issue, Samsung/Microsoft will fix it. Hope so.
Please post here if you have this issue too.

I have also been having this issue... sometimes it doesnt come back straight away when i restart it but after about 10mins its back.
When I activated it with orange I was told to expect a few txt msg's that would need deleting and the phone restarting... I only got 1 msg, maybe this has something to do with it, maybe the phone hasnt been sent enough updates.

I also have this issue and have done for weeks. Orange couldn't solve it either.
It only happens overnight at home. I either need to reset the phone / rescan available networks or turn flight mode off and on again for the connection to restore.
I was thinking it may be an issue with t-mobile since it only happens at my home where orange signal is poor and i roam over to t-mobile.
If i stay in an area with good Orange signal i don't get the problem.
Good to know i'm not the only one with this problem. It's very annoying!

Hi y'all.
I had the same problem: 3G was lost every time. I was fed up restarting the phone every time, so I looked for another way to get 3G back. I found out that disabling and enabling SIM security (phone > setttings) got me 3G again... for a short while.
But: after disabling SIM security permanently, 3G kept on going (in fact for over a week now).
I think that changing the PIN to some other number, might cause this. I haven't yet tried changing it to the default PIN again, to see if using that for SIM security solves it. For the moment I'm too happy it works again.

I have suffered from poor reception issues ever since I got my Omnia 7.
It seems like the reception comes and goes. I will receive e-mails, which proves that the phone has been connected, but as soon as I try to use data myself, by visiting a web page or refreshing an app like facebook, the reception disappears and the "no reception" symbol drops down from the status bar.
Also, often when I try to send an SMS, it will appear to have been sent, yet 10 minutes later I will receive a "Can't send...try again" message. Once I have received this, the SMS will never successfully send. However, in the meantime I can receive SMS messages, which shows that the phone has been getting a signal.
This is SO frustrating and is ruining my experience with the phone.
I have posted requests on the Microsoft Answers forum and the only suggestions have been to reset the phone or turn WiFi off. Neither of these have had any effect. I have never enabled SIM lock.
I have heard that there is a firmware update due soon which includes a new radio stack. I am desperately hoping that this will improve the situation, as at the moment I cannot rely on my Omnia 7 as my only phone.
Alex.

Hi Loco,
You are right in saying that social answers doesn't really help much .
Luckily there IS a new firmware from a couple of days ago! Check out the Omnia 7 Dev section. There are only a few posts.
And here is also a good link for you. You are right to assume that it comes with a new radio stack which improves on performance.

Finally found a thread on this... I have been having a similar problem since I got my phone from Optus here in Australia. I took it back and they replaced it for me but the new phone is exactly the same. I don't lose the 3G icon but anything data related just ceases from loading. Right now I'm trying to refresh the Facebook app and it just comes up with 'Unable to connect', even though I have full 3G reception.
I flashed it to the newer leaked firmware and it hasn't changed anything, problem still persists unfortunately. This is a major problem that isn't getting enough attention! It seems quite widespread and Omnia 7 specific.

Had similar problems, but after I changed my provider ( O2-Germany), 3G is stable.

For the people having this problem, have you tried setting the phone to prefer 3g? Details of how to do this are here http://forum.xda-developers.com/showthread.php?t=915813

Same here man. On Optus and my reception sucks with this device. What the hell is samsung doing? FIX IT!

I have been having this problem with my Omnia 7. The frustrating thing is this is a replacement phone I had for an LG which I had replaced THREE TIMES due to random resets. So now I have a phone that I have to turn off and on EVERY MORNING in order for the data connection to start working again. Needless to say I am very frustrated. I am on Orange in the UK. I suspect it could be related to when being an a poor reception area and it tries to switch to tmobile. I am going to try turning roaming off. Please, if anyone finds a solution to this let me know.
Thanks

My problem got worse with the Mango update. I'm now on my 2nd handset after having a replacement from Orange warranty. This one still loses it's connection but much less frequently.
TBH i don't think it will ever get fixed. I started an MS Answers thread months ago and lots of people had the same problem but we never got a response from MS.
Conisdering the age of the model now I doubt Samsung care, well they didn't seem to care a year ago so they won't now... For this reason I will not buy another Samsung phone. It's infuriating.

Looks like I am stuck with it until December then when I can upgrade to a Nokia lumia. A long wait :-(

i have this issue, too.. but for me i only have to set airplane mode on and off. sometimes i deactivate data connection, go to a random website, get the 'no connection' error, then activate data connection back and it works.
however, after installing the latest drivers & firmware, i get this issue A LOT less frequent. like once in 2-3 days.
i hope ms or samsung will fix this because it can get really annoying. especially when you need eg. a quick google-search..

Just flicking the flight mode wouldn't be so bad but that doesn't work for me, I have to restart the phone each time. I love WP7 but this and the other problems with the LG is driving me nuts. Almost wondering whether I should have just followed the crowd and gone for an iPhone.

Same as me - Flicking flight mode on-off doesn't solve it, needs a soft-reset.
Like I say, there are quite a few with Omnias on Orange with this problem.
I'm in the same boat, I've had this for months now so I guess I'll just deal with it until I can upgrade the start of April and get a Lumia (hopefully the EU 900/910 will be here by then!). There is no way on this earth Samsung are getting any more of my money. Nokia seem fully commited so they can take my cash next time!

I have the same problem with the data stopping working on o2 in the UK. But I also sometimes cant receive calls even though the phone has service, then there are the times where it site there going GPRS/3G/3G+/No Service and you cant do anything with it apart from pull the battery.
