Drops phone signal and then can't pick it back up? - Advantage X7500, MDA Ameo General

I am using a 7500 in London England and WM 6 (though it was the same under WM5). It is also the same if I switch a SIM from O2 to 3.
When I come from a place of zero GSM or 3G signal, such as leaving the underground train and coming to the surface, the phone refuses to pick up any signal again. This has never happened with other WM phones I have had - I also use the TyTN II for example, which is just fine.
I can wait for hours, but it refuses to locate another signal. I have to shut down the phone, then start it up again. In fact, there is plenty of signal.
It is starting to get annoying.
Anyone with experience of this? Any solutions?
thanks

What Radio do you have installed
There are links to radio 1.57 and 1.58 on the following page which seem to have improved phone reception and battery life
http://forum.xda-developers.com/forumdisplay.php?f=353
Remember to back up your files as this resets the rom

thanks for that. I have radio 1.50 at the moment so I'll see if this improves things.

T-Mobile 4.00.10 beta stability?

:?:
How's the new one holding up? Anything different from the other WM 2003 betas? What about the problems with SD cards getting erased for no apparent reason....has that been fixed? :-D
Well since its the T-Mobile test ROM, we got back the following:
Today screen plug-in that displays T-Mobile, Call Log and Voice Mail
SMS Message from the New menu is back
Battery Monitor is back on the task bar (the one at the bottom of the screen).
T-Mobile is being displayed as your carrier as it should on the phone display.
Battery life is much improved as with the other betas.
Your T-Mobile connection settings are back.
Its pretty stable to me haven't had any problems with Alarms, erased SD cards and the such.
HTH
I upgraded the ROM yesterday and kept the AT&T A.20.10 radio stack. It definitely seems more stable, although the signal strenght meter shows weak signal, but I have not had any problems connecting.

So it is the radio stack that controls the signal meter and not the ROM!
I also forgot to note that the SIM Tool Kit has been removed from the T-Mobile ROM.
Stability
I've had major stability issues ever since I installed the T Mobile rom on my Qtek P1010 (PW10A1, O2 Radio Stack 4.21.00).
The xda has crashed on me on many occassions, I've been stuck in the middle of a call without being able to hang up, have had issues taking a call, and even using the buttons.
Using the TMO rom on O2 XDA - stability seems fine - not yet erased an sd card, the GPRS works fine, but the phone buttons do not seem to answer or drop a call - I have to use the screen options.
Hmmm. I think I read the 4.00.05 beta had the phone button problem too. Or I could be wrong...
I've been using it for about 3 days now w/ no problems. About 100x better than my 3.17 ROM from TMO. It's about time I can rely on this thing. Call quality is much better and I no longer drop calls where I did w/ previous radio stack & ROM.
working fine for 24 hours.
I upgraded to 4.00.10ENG ROM and the 6.24 Radio stack yesterday. So far, it works great.
The signal meter is trending a little bit lower than when is was running the ATT radio stack, but the call quality is better.
Is it me, or has the ability to disconnect a GPRS connection gone away? I have to turn off the phone to break the connection.

XDA Exec Problems; Signal & Today Screen

Hi,
I have an O2 XDA Exec with the latest ROM version, on an Orange Pay Monthly SIM.
Anyway, im having two annoying problems with it;
Firstly, every now and then, if you have a few programs open and close them all, it wont go back to the Today page!! It will just keep the image of the last application on the screen! Today wont even come up if you goto Start > Today. Everything else works fine though, can open any programs etc from the Start Menu :?:
Secondly, the phone signal is rubbish!!! My old SPV C600 had no problems with signal (also running WM5), this one has low signal/looses signal all the time! And after a while it will just stop searching for signal, so i have to go to settings and tell it to search again!!! I constatly have errors trying to send messages due to no signal, and cant make calls due to no signal!! Also i dont recieve texts alot aswell! Which is un-acceptable from a device that is meant to be a "mobile phone" :roll:
Any ideas to solve?! Please help me!!
Thanks

Hey Matt
what are your ROM versions? especially interesting in this case would be the Radio version. I think people round here have mentioned that different Radio versions have different signal reception levels.
I am using the O2 XDA 1.30 version with stock radio 1.00.09 and basically the reception's fine. There have been some comparisons on this forum as to different radio versions strengths and weaknesses.
Hi very similar to me, I switched off the 3G usage so it only uses 2G and everything was perfect again.
Now I only use 3G as and when I need it.
The problem as I see it, is that if there is a 3G signal, which in Orange's case appears to be nearly all the time the phone sticks with 3G even thought the signal strength isnt good enough fo voice, but is good enough for data (mainly because you tend not to be walking around) because of this the switching between 2G and 3G doesnt take place, hence no calls
Since swtiching of 3G my phone operations have been perfect.
I switched my Radio ROM from 1.03 (Orange Default) to 1.09 and noticed an improvement. Where I had no signal, it would flick between a signal with no bars and 1 bar with the 1.09 ROM.
I switched my Radio ROM from 1.03 (Orange Default) to 1.09 and noticed an improvement. Where I had no signal, it would flick between a signal with no bars and 1 bar with the 1.09 ROM.
As soon as i got the XDA i upgraded it to the latest O2 Rom, which has 1.09 Radio Rom... so i dont have anything to compare to!!
Any more suggestions?
turn off 3G if you dont need it.
send it back, you may have a loose connection.
are you saying a bad connection 100% of the time? ie you never have full bars?
Ok i'll try turning the 3G off (seeing as my SIM doesnt have 3G capability anyway! lol) How do i go about doing that?!
I do get full signal in places yes, its just the signal is utter crap on this phone compared to all of my past ones! Compared to an SPV C500 & C600 its rubbish!
start - settings - phone - band
change to your standard not auto. probably gsm rather than cdma.
do you get a bad reception with4 bars?
either way, I must say I have no problem with phone, but acknowledge many report poor phone performance.

1.20 Radio Rom takes long time to reregister on network after dropped off?

Hi all,
I'm currently experiencing a problem where my Softbank X01ht drops off the cellular network because I live in a low strength area, and takes forever, if at all, to automatically connect back to the network, even if I move into an area where I know the cellular strength is high.
If I manually turn off the phone portion of the hermes, and reconnect, then it happily detects the cellular network and connects. In other words, after disconnecting, it acts as though there is no network in range at all, even though I know there is.
This seems to have started after I upgraded my radio rom to version 1.20 from 1.07. Prior to the upgrade, I know it connected back to the network quite quickly after it dropped out. Has anyone else experienced this with the 1.20 Radio Rom? I currently have the Imate jasjam rom installed on my phone with the 1.04 bootloader.
Unsure if this is related, but the area that I live in has a weak UMTS network, but a relatively decent GPRS network. I'm thinking the phone is getting confused over which network to connect too.
It also seems that if I'm in an area with a pretty strong cellular strength, it doesn't drop out? Would I benefit from downgrading to the 1.16 Radio Rom?
Thanks in advance all.
Gene
I can also confirm that things added with that after a soft reset sometime it cant detect network..i have to manualy turn off/on the radio part....generelly it occures if i reset the set just after making a call or just getting disconnected from edge...
the previous 2 radio that i used 1.16 and 1.08 didnt suffer from those probs...
but the main benifit of 1.20 radio that i get is EDGE speed i can pump upto 220Kb (22-24 KB) download speed in flat when connected to pc as wireless modem but with the previous radios i can barely go 160Kb and the speed did uped/down regularly...
and somewhat strange with this 1.20 radio i cant search for network list manually when even i go to manual in network after sometime i get cant read error...but previous radios where ok in that par too...
and the last benifeat that i get with 1.20 is now the SIM STK menu is working.....

Thanks sajib,
Glad I'm not the only one experiencing it. For me, however, it only occurs when it looses connection to the cellular network. After every soft reset so far, it has connected to the cellular network automatically. To me it doesn't seem to even search for the network. That is, after loosing connection, it is resigned to the fact that it can't connect to a network, so doesn't even try, unless I force it too. I think I have seen it connect automatically once or twice, but either way, it takes at least 10-20 minutes, sometimes it never connects, and I force a manual reconnect by turning off the phone and turning it back on. So is this a known problem with the 1.20 Radio Rom?
Try this...
I had the same problem on my TyTn. Took forever to WiFi connect. Then I found this registry setting:
[HKLM\Comm\TIACXWLN1\Params]
"dot11ShortPreambleInvoked"=dword:00000001
Now my WiFi time-to-connect seems much faster.

Hi!
Thanks for the advice, but mine isn't a Wifi problem, but a problem with connecting to the cellular network.
Or do you think that your connecting to the WiFi network and the cellular network are one in the same?
i am using the 1.20 radio as well, but cant say that i have had any of the said problems... i have the cingular 8525 and have used the 2 latest cingular roms, the aku2.3 and 2.6.. but i did have some of the same problems with i used cingulars 1.16 radio

Do you commonly get cellular network disconnects? I find that if I'm moving around the city or driving around in the car, the network connection is maintained, and sometimes will automatically find the network if it does get disconnected. However, it is only when I am home that the phone disconnects and doesn't try to reconnect once it has been disconnected.
Any idea of what might have caused this issue with you with the 1.16 Radio Rom? Possibly something to do with the AKU version? I'm using AKU 2.3.
Thanks,
Gene

I too have the original problem but have not upgraded the radio ROM. I have the T-Mobile Vario II (sorry not sure what ROM that is) but often when I move from an area of either very weak or no signal to an area with a signal (coming out of a shielded building) I too get the same problem. Initially the phone shows weak (or even strong) signal strength but when I try to make a call I get the box up on the phone screen telling me it cannot connect. I have found that eventually it will, when left to it's own devices, get itself sorted out and allow a connection. But it is invariably quicker turing off the phone (via comm manager) then back on - this always results in a valid connection.
Perhaps the problem that you describe is not related just to the 1.20 Radio ROM upgrade?

Hi Tony,
It could possibly be an application or the ROM itself causing the problem, however, I think its the radio rom in my case, simply because this problem only started occuring after I upgraded to the 1.20 Radio Rom. Previously on the 1.07 Radio rom, the phone would connect automatically and immediately. Also I just performed a hard reset after I discovered this problem, and it still seems to be occurring...
I also am sure that after a long while the phone reconnects, I have seen it try reconnect a couple of times. But then again, a couple of times I've left it for 10-30 minutes, and it hasn't reconnected. Unsure of exactly how it chooses to reconnect and when it tries to reconnect. You would think it would try reconnect constantly after a specified period, but in my case it seems very random.

i actually get pretty solid coverage whether moving or stationary. especially at home since i live not a quarter mile from a cingular tower and i dont think its necessarily related to the aku version since i have gotten the same result with either 2.3 or 2.6. But i can say for sure that the cingular 1.16 radio is junk my biggest complaint was gsm calls cutting out and on my calls on 3G had a very weird digitized background noise, kinda sounded like a bad digital echo... 1.20 fixed all of that for me

When I'm roaming around my connection always seems to be sustained. e.g, I've been checking my phone ever 1hour for about 24 hours, and have yet to see my signal lost. Is it possible that the phone is getting confused over which band to connect to? As I said in my first post, I have a relatively weak 3G/UMTS signal from my home (1-2 bars), and a relatively strong GPRS signal (3-4 bars). Presumably the phone is UMTS-preferred, and uses GPRS as a secondary.
I saying this, even if I go to another area which usually has 5 bars UMTS signal, I haven't seen the phone immediately connect. This was after about 10-15minutes waiting in that area.

yes, the phone is set to prefer the UMTS bands.. have you tried setting the band manually instead of it letting it autosearch? you can do it in the phone settings menu or use the app listed here: http://forum.xda-developers.com/showthread.php?t=286844

Vario II network coverage question

Recently my Vario II intermittenly loses network signals, it says No Network and I have to toggle phone off/on to make it search for signal again. This only happens when I'm at home (Charlton SE7 area).
Rom 1.21.110.3 (19/06/06)
Radio 1.05.05.00
Does anyone have the same problem?

Flash HardSPL first, then upgrade your radio.
Ive linked to my guides incase your unfamiliar with the process.
The newer radio should possibly increase your GSM efficiency. Are you in a decent area for reception?

Hi, many thanks for your detailed guides. I've upgraded Radio to 1.38.00.10 but the problem still persists. I'm in a very good coverage area, always get full bars 3G when it works. Soft-reset my phone and now it's searching in vain for network signal, I'm confused
What operator are you with ? Maybe the cell where you live is getting overloaded. We had a problem similiar to this last month when our local base station had a problem. Our work-around was to disable 3G but not using a Hermes . Apparently the handset tries to register using the 'best' data-bearer its configured for. So disabling 3G made it register with GPRS which worked fine. They then fixed the base station and we were able to re-enable 3G. I would
guess Charlton would have a lot of subscribers per cell. You would expect the coverage to be better in a built-up areas but who knows. Maybe an enquiry/ complaint to the operator would at least tell you if they know of a problem and if its temporary or longer term
Cheers for that. I'm with T-Mobile. What's bugging me is that this signal disappearance only happens sometimes. It's not that I don't have 3G (or signal for that matter) at all, I still get full 3G signals fine most of the time. But you probably were right, looks like it's a fault from the operator's cell in the area, I will give them a call next week to see if there's an explanation.
I've noticed this problem when I'm in the south London area (very general I know). People have got around the issue temporarily by forcing the phone to GPRS only
More problems! After upgrading to 1.38 and trying all sort of "good" radios like 1.17, 1.27, 1.34 I can't make/receive calls unless GSM is forced. There must be something wrong within my immediate area because with the same radios everything works flawless just 10 mins down the road. I just called TMob and there's no technical fault or anything from their side. I will just have to put up without 3G until the problem fixes itself
There are lots of people complaining about 3g on T mobile in UK. They seem to have serious issues with Hermes devices and the dropdown to GSM.
I had a problem six months ago with my hermes on orange at home in SW London. For a few weeks it was mucking about - I rang O who advised me that they were experiencing some local issues but would fix them within days. I switched to GSM for a few days. When I switched back its worked fine for last five months.
3G gone mad!
the same thing was happening to me. Full 3G reception in Leicester, tried to connect to get my e-mails and then the signal totally goes. The same thing happens when I make calls as well. Switched to GSM and everything worked. Now in York and everything is working on 3G.
Network is T-Mobile.
This sounds similar to the issues I am having.
Do you get the phone hanging as it attempts to start a call and then after a while a message stating that it was unable to connect?....sometimes resulting in a soft reset to bring the device back online? In my case toggling bluetooth will reset the connection.
I am with T-Mobile in Glasgow but get the same issues during the day in Edinburgh
No 3G

No mine doesn't say anything, it sounds "ding ding" after a few secs like when you press the hang up button. I can use the Internet but anything to do with calls is just impossible. I've switch to GSM now and everything's back to normal. A bit annoying can't use 3G at home.

Is it just me or is anyone eles having a signal problem? in jfadp1.5

since i had updated to the new radio my signal been dropping randomly out of no where then comes back.. i had about 20 drop calls since i had flashed to the new radio from haykuro blog and the magic spl. and then i had use JF adp1.5 and that when my E and bars stop dropping.. anyone out there know whats the problem? or is it just t-mobile towers
same thing happened to me. not sure what the issue was but i re-downloaded the radio file from htc, updated the pone and things were back to normal.....actually better.
after the update my signal strength improved. in areas i normally only get E coverage, i now get 3G. in areas i had marginal 3g coverage i now get more bars, etc
aiight cool, cause i was having the same exact issue...so I'm going to reapply the latest radio update...thanks guys.

Same here.So happy.
I was wondering where I can get the update for this?
I have had huge problems with the 1.5 radio for the Dream (2_22_19_26I) ever since upgrading. I even tried to reinstall the radio, to no avail. I still kept losing wifi every x minutes even though the status icon reported a strong signal, and the only way to get it to work again was to restart wifi manually. I also lost positioning via the 3G/GSM network after xx hours, and the only solution was to reboot the phone.
Anyways, I decided to revert back to the 1.1 radio, 1_22_14_11, which seems to have fixed these issues.
where can i get that old radio download?
HELP!!! updated radio now phone get no service!!!
i updated to the new radio just like everyone else then my phone starts dropping my data connection...NOW i reverted back to the 1.1 radio that i downloaded from htc and i still get no service!!! HELP!!!

Update:
Ok, so the old radio did not fix the problems, which means this is either an issue with Android 1.5/JFv1.50 or I have one or several apps installed that is causing this. A possible third option would be a funky SD card.
