Won't reconnect after losing signal - MDA, XDA, 1010 General

My XDA phone seems to work just dandy...as long as it doesn't lose connection. If this happens I invariably have to switch the phone off and then on (not the whole xda) for it to pick up the signal. Sometimes when I do this it jumps up to full strength so it's certainly not signal problems.
Is there same way to force a signal search without turning the phone off? It's very annoying as I miss calls because of this assuming i'm connected when in an area with good signal (central london say - no i'm NOT in the tube!)
Thanks for any help here.
Daniel

You may want to upgrade the phone software. I used to have this problem on older RSU versions, and it disappeared somewhere along the road. 4.21 seems fine.
(The XDA will never be the phone for rural environments though. Radio reception just doesn't compare to e.g. the better Nokias..)

Thanks kindly for your reply.
ROM Version: 3.17.03 ENG
Rom Date: 05/15/03
Radio Version: 4.21.00
Protocol Version: 32S54
Anything wrong there? Would it be worth reinstalling the radio stack perhaps?
Do any of you XDA pro's know if there is actually a function to force a re-scan of frequencies to find a connection? How difficult would it be to write one as I could see it being incredibly useful even for people who's phones DO reconnect themselves (After a while).
Best regards,
Daniel

Hi Daniel, I have the same problem as do 54 of my colleagues. I have just had to rollout these XDA's out to my colleagues as part of a real time
information project and all have the radio stack 4.21 installed. If the guys are in a dead phone area in excess of 30 mins, it will never find the network again until we do a POR. I guess that the firmware either has a retry limit then gives up or it is done by time then gives up. I sure would like to see if this can be resolved?

Yep, I too have the same problem!!
And it's a pain in the arse! Anyone have any ideas? I have the latest firmware, radio stack etc from o2 UK.
Any of you technical sort of people know?

What we need are two little apps...
1. An app that will run the "reconnection" process without requiring the pin number to be re-entered.
2. a "cron" type program that will run it every 30 mins.
But I'm dammed if I have a clue how to do that!! =) Techy types...heeelllppp!!!

I'm in asia and running the same 4.21 have the same problem using the 900 band but with the 1800 frequency it's ok.

I'm in Argentina (GSM 900-1900), same problem. Tried different PPC versions / Radio Stack versions. Now it is:
ROM version A.30.09 ENG
ROM date: 01/01/04
Radio version: 6.24.00
Protocol version 324e4
(Hardware model PW10B1)
I hate going somewhere and when I get there check the green light just to see if it blinks and it doesn't! And when I turn on flight mode and then off, I get a strong signal. I can't have a phone like that! Why it doesn't check for signal automatically???
A solution would be to have a program turn on the PDA with the backlight off (to keep battery life) at predefined intervals, check the signal and if it is OK turn off the phone but if it is on No Signal "tap" on the signal icon, then on Turn On Flight mode, then repeat. That would be a quick and dirty solution. I would love to implement it but I don't have the resources (you can read programming knowledge) to do it.
Kind regards,
Marton

I also have this problem (in australia) but only noticed it since upgrading to the latest firmware. Hopefully when they do their next release they correct the problem agian.

If you happen to find a revision that doesn't have this problem, please let me know!!! Thanks!!
Marton

What happens when you try to make a call after you have lost the signal, and are back in an area with signal?
I did have the same problem- every time I came out of the underground.
It would often say 'Unable to make the call' etc.
But then i found that sometimes, if I called voicemail, the phone would pause for 30 seconds, then suddenly re-aquire the signal.
This seems to work most of the time now.

When I turn it on, the signal icon starts "Searching" and the three dots go blinking endless without getting the signal. If I turn on flight mode on and off, signal comes in normally. It is very strange but it seems too many people has this problem and it's sad that there's no aparent solution
Marton

Yup. But i found making a call (e.g. to voicemail) even when it shows 'no signal' did force it to start searching for a signal, although it freezes for 30 seconds.

OK, but I have no problems with turning on and off flight mode to get the signal back to make calls. The problem is that the phone can't receive calls.....

This sux
I was kinda hoping I was the only person with this problem, or that I'd find sum1 else had the same problem & knew how 2 fix it... I just purchased a Wallaby on eBay, but am becoming EXTREMELY frustrated with the lack of reception (0-1 bars connecting to Optus PrePaid within Australia) and when it frequently loses the signal all 2gether, I have 2 reset the phone 2 get it 2 pick it up again. VERY annoying. If ne1 knows of nething that might help (I no very little about all this ROM/radio stack stuff) then please, let us know!

Hello,
How are you?
I also have this singnal problem.
Has anyone found a solution for this?
I am running radio 4.21 in France.
Does anyone know if there is a later version of the radio stack?
thanks for advice,

Phone Loses Connection to Service

This has started to happen recently. I am with AT&T Wireless in Brooklyn, NY. The phone used to carry the signal around almost the whole day and never lose it, but these days if I leave it alone for a while and come back it may say "no service" or "searching..." . If I do a soft reset it may find the signal, or if I turn wireless off and then on (which doesn't always respond, by the way -- on my phone it's called "Turn on Flight Mode". Is that what it's supposed to be called?)
I got this phone two months ago and I am extremely thrilled with it. It's a phone, pocket pc and (video!) camera in one. Sometimes it can achieve great clarity on conversations.
I wish someone can help me out though with some advice or information on upgrading the phone. I have the following questions:
1) What GSM frequencies does this phone use? Can I make it work with AT&T's 850 band? Is anyone familiar with making this phone work better with AT&T wireless?
2) What are some of the icons I see on the top, such as the G in a square? On my old phone that used to mean GPRS connection (i.e. internet/wap). I don't know how to control these things. To turn wireless off, I click a link that says "Turn on flight mode."
3) Finally, what can I do to stop losing the signal?? I tried putting manual selection of the AT&T Wireless network on, and it didn't improve things -- the phone still lost the connection. Once it had the connection thoguh, it didn't drop it -- I don't know why the connection gets lost.
Thanks a bunch for any advice and info,
Greg
Egreg,
I have similar problems. My provider uses GSM 1900 & 850.
1) It uses GSM 900/1800/1900. Unfortunately doesn't have an 850 radio; which is really bad, they should have made it a Quad Band for the price we pay for it. GSM 1900 is really terrible in buildings etc.
2) G Means the radio has negotiated GPRS availability.
3) I've gotten better results with signal locking on by following this thread:
http://forum.xda-developers.com/viewtopic.php?t=7619&highlight=signal
Download the application and set it to "Search GPRS on start GPRS connection". That way it doesn't have to negotiate for GPRS unless you actually want to use it (helps to establish signal lock much better as there is less protocol overhead).
Also now, I'm using Radio Version 1.06 & 1.08 as they seem to reconnect much better than 1.14.
Hope this helps.. Mine is performing much better now, not perfect, but not as annoying.
Thanks. I'll download the GPRS tweak program. Will that alone help the situation a bit? All I need is the voice capability, I won't use GPRS, only the GSM voice -- for internet browsing I may get a WiFi SDIO card from SanDisk.
I thought that changing to some other Radio software would help, but I heard on this site that changing the OS is risky. Can you tell me what I could do to get some a better connection, perhaps guide me through installing a correct version of Radio?
I haven't had this phone for very long, so I'm unsure if I should attempt to upgrade/downgrade.
-Greg
Greg,
I think the tweak program will help things a bit.. As I mentioned I am able to get signal seemingly quicker when I have it set...
I was pretty paranoid about OS upgrades, but I've gone through about 4 versions so far. This week is the first time I ventured out to use a different radio version than what comes with the upgrade.
Try the tweak and see how things go for a while, and then make your decision to upgrade your ROM...

HSDPA and dropped calls problem with Hermes

Hello all
I was just wondering.. I noticed shortly after I bought the Hermes that I did not receive calls when the Hermes had a HSDPA connection. Collegues were complaining they got my voicemail while I was in the car.
It turned out that TomTom Navigator used HSDPA to retrieve traffic information and as soon as it was on HSDPA, people who called me, got my voicemail instead of me and my phone never rang . When I reduce it to 3G I didn't have any problems. I never used HSDPA again and always disabled it in newer roms.
Now, I assumed it was a firmware-issue but I never persued it any further. I tried several Radio roms but I experienced it with every single version. I forgot about it but I recently remembered it and I got the idea of asking all of you if you also experience this problem or is this something that is going wrong with either my Hermes or my provider?
Thanks for your comments!
I'm just throwing my ten cents in:
I've had similar problems with my Hermes: I'll be on a call, then the call will go silent (even though my screen says "Connected")...then, about 5 seconds later, the call ends. Most of the time, when I've thought about checking, it appears that it's happening when my phone is either trying to get a data connection, or has one active. However, it can happen when my phone has the "3G" data connection speed symbol; it doesn't appear to be limited to HSPDA for me.
I'm not sure if it's a problem with the ROM or the radio...There is a newer radio version, but I've heard that the one I have (1.48.00.10) is the best one, functionally. I'm wondering if it's the ROM I'm having issues with, but I REALLY hate the idea of flashing a new ROM.
If I get a solid answer, I'll let you know more, but it's something of a mystery to me, too right now.
The problem that you are facing has nothing to do with the radio firmware in your phone but instead caused by the Operator's network. It is known that certain versions of the HSDPA (early versions) implementations does have limitations where if you are on HSDPA, calls cannot come in.
This limitations should have been resolved in the new HSDPA implementation which is a mere software upgrade in the basestations.
Hope that this shed some light on your problems.

So, basically, what you're saying is that my provider is running old software in their basestations
Can you define "old"? Are we talking about weeks, months, years? My provider claims to have a top-of-the-pops network but if what you're saying is the case with them, they are not living up to their contract. I pay about 75 Euros (about 110 dollars) a month for degraded functionality. If that is true, I will file a complaint, ofcourse.

**SOLVED!!** Any 3.27 Radio-based ROM & signal reception issues

hey everyone, maybe I have a bogus phone, but I've tried multiple roms based on the 3.27 antenna, DCD's WM6 & WM6.1 versions.
Each time, after the flash (both radio and rom) it takes me over 5 minutes to get a signal (RT or EVDO). After it gets a cell signal, everything works fine including GPS. But after each soft reset, it takes me 5 minutes to get a phone signal again.
I thought it was the ROM, but after trying it with multiple versions, I am at a loss.
Any ideas?
FWIW MSL/MDN/MSID codes are intact and correct. Signal area is consistently 4 bars. Phone functions fine after getting a signal.
**SOLUTION**
1. Have MSL code ready
2. From phone app, type ##PST#
3. Click EDIT
4. Type in MSL code
5. Click VIEW INFO in bottom left corner
6. Click M.IP SETTINGS
7. Change value of MIP REGISTRATION RETRY to 1000 ms
8. Change value of MIP MODE to MOBILE IP PREFERRED****
9. Click MENU in bottom right corner
10. Click OK
11. Soft reset device
**** note, I had to adjust MIP MODE 3 times before I got it to work.
Thanks everyone!!
especially limezednem!!
no issues so far. My phone boots up super quick now since i did this wm 6.1 and radio update. Feels kind of naked but love the speed. It has frozen on me on multiple occassions when trying to uninstall certain programs but as far as phone connectivity, i have had no issues since i got it working. Connects right away.
I had the same issue. I flashed back to the original ROM and it signal was acquired in a flash. I have since swapped the phone from Verizon, but I am reluctant to re-flash, though I REALLY want the GPS functionality... please some one come up with a cure for this slow signal malady!
anyon else had this issue?

I originally had problems with the dreaded Error 67 with the new ROMs (tried everything). I went back to the stock Sprint ROM and it disappeared.
On a whim I tried the upgraded ROM again (glutton for punishment). After it rebooted I couldn't get a phone signal... I went into Connections and turned off the phone and waited a minute and then turned it on again. Got a signal in less than 10 seconds. (Error 67 are gone too... go figure!)
Try that.
I'm w/Sprint and had the same issue with radio ROM 3.27,it took about 2 minutes to get cell signal after soft reset,then the data connection got disconnected every single,i was so frustrated since i did a lot of internet radio streaming and IMing.I flashed it back to 2.17,all is working fine with the old ROM,I think i can live w/o build in GPS for now.
You might have already tried this, but if not, try flashing to DCD's 2.1.0 ROM with the 3.27 Radio. This is the one and only ROM I've ever flashed to and probably ever will flash to unless some godlike official update is released. I stuck with this because I feel it's *easily* the most stable, has fully working BT AND has GPS & Rev A enabled (network permitting).
If you haven't already, try 2.1.0.

Try programming your phone OTA, and updating your PRL.
*22803 for telus, *228 for some other carriers. Not sure what you have, but that could be your issue.
Mine did this at first, I dont know what I did to change it but it went away. Problem is, when I updated my prl to 60711 or whatever the new one is, the problem came back. I reset on my way to work and it didnt get a signal until well after I parked (15 min drive) but for some reason sitting at home it would get the signal within 2 minutes. For me it hasn't been that big of an issue since I only soft reset once a week or so. But I am scared that this will occur in a time of need. Glad to hear there are others out there who share my problem.
SAME THING HAPPENED TO ME.. i made a thread about this too....
did you get it resolved?... its really frustrating.. i flashed it flawlessly to my room mates phone... then failed on mine.. figured it was my phones fault.. got a new one... and SAME thing on the brand new phone... where am i going wrong?
all ID numbers were correct... esn, mdn, msid. etc etc.
help me please
same EXACT Thing happened to me.. with 2 phones.. however, I flashed my room mates phone flawlessly and is still working without an issue...
double post... damn computer
no luck.
sticking with 2.17 for now.
i have SORT OF the same prob............ i get signal right away but it fades in and out from evo to 1x and back ...... sometimes it can take me a half hour to finally connect a phone call because of it.
any ideas?
bump because i really would like to know why this is happening to a few select people..
maybe ill just wait for sprint to release the official rom/radio... and go from there
I went back to 1.4 radio and custels 1.1 rom, now my internet isnt working....
go figure
i have a feling it might have to do with prl's.
try ##786# reset it and then load latest prl i hope this work
I have the latest PRL, still no luck.
I have Verizon and just dial *228 and when prompted press #2 and it updates my roaming capabilities (PRL) all over the air with out having to look for PRL's over the net and manually updating them.
I don't know if Sprint has this feature but if it does try it out.
Ohh yeah i was playing with the registry and found a way to make your signal stronger ( I think ) I don't know if it realy does work but it give me higher bars
go to
HKLM -- System -- State -- Phone
There are two strings.
One is Signal Strength and Signal Strength Raw.
I change the value to 100 on both and get full bars. I dont know if it does give a real effect.
But after a little while it goes back to the original signal value

diid You do ##786# and reset phone ?
I have the sprint 7800 with 6.1 mobile and I am having an issue with my reception as well with this radio. When I make / receive phone calls I get a crackling sound. It's faint but none the less enough to be annoying whne talking on the phone for awhile. Any one else having this problem or have a solution to it? Thanks ahead of time.

No more constant "H" icon on recent builds?

Hi everyone,
I'm just wondering if anyone has had experience with the H icon not showing constantly on the recent 6.5.1 builds. I still get it when downloading, so HSDPA is still working, but it no longer shows up constantly. Seems a lot like on my old Hermes, which only supported HSDPA (but not HSUPA). It may be that there are some issues at my carrier, but I just wanted to confirm that noone else has seen this before I contact them...
I'm currently using Timolol's 81 build, was on the 71 for the last few weeks, had no issues before that, though I think I had a brief period back at the start of using 71 where it was working fine...

T-Mobile Netherlands?
TPG (Optus) Australia ;-).
Using Radio 1.14.25.05 and 1.14.25.35 (the only two that work reliably with GPS)...
do you have touch pro config or advanced config type tools installed? They can do a registry tweak that can close data connections after X minutes of inactivity. On mine with this option set (to 1 minute) i will get the H icon with signal strength (as opposed to the other H icon on the left which is always there) when a connection occurs and it downloads something, then 1 minute later it goes back to the antenna icon with signal strength (and you can see in HTC COnnection Manager that Data Connection has now been switched off).
Perhaps you have this setting/option set now? In general leaving the data connection on all the time cant be as good for battery etc, especially when the connection is re-established whenever something like activesync or your browser requests it anyway
Thanks for a good suggestion, however, sadly this is not my issue. I am still maintaining connections (on 3g) when not downloading. I did wonder if perhaps MS had tweaked the power management in new builds to drop back connection speed when not in use (Symbian does this, though it drops back all the way to GPRS) but don't think this is the case. Is there any way other than via the icon being constantly H to know HSUPA is working?
In relation to battery and the auto disconnect tweak, I used to use this but sadly it breaks simultaneous voice and data, which makes it a no-go for me (nothing worse than downloading a file and having it bomb out due to an incoming call).
I'm on ATT, and lately the only thing that's happened is H has been showing up more. I use the .25.35 radio and the newest NRG ROM and it works excellent. Hope this helps.
I believe that AT&T have recently increased their coverage significantly for HSDPA in the States...
We've had it over here in Australia over quite a large area of the country for some time now, and it was certainly working well for me before. I've just called the network, but they don't have any information about faults. I'm currently trying to deprovision and reprovision my data service, and hope that will help (I wonder if it's something to do with me at one point using unmatched RILPhone DLL and radio...if that did something funny on the network perhaps they switched something off for my phone. After I tried that, I put it to radio 1.14.25.35 (+matched RIL), which worked fine on H again, but a bit later I changed to 1.14.25.05 (+matched RIL) as I get better battery life with that one...no luck on that, but since then changing back to 1.14.25.35 (+matched RIL) doesn't bring the magic H back either :-( )...
OK, just flashed back to stock to see if that helped, and no luck. So it's not the new ROMs, and it's not anything on my phone. I guess the phone company has either detected me doing screwy things with my radio and switched off my HSUPA for some reason, or more likely, have screwed something up or switched it off in my city for some reason.
All i've got to say about that is BUGGER!
Back to my nice new 23081 w/1.14.25.05 radio then...
Hi caeci11ius,
I'm on virginmobile(Optus) as well. I noticed the same behavior with various new WM 6.5 roms (I'm on latest Exquisite now), but an old EnergyROM build I had which used WM 6.5 21016 build was on H almost all the time.
I think Windows Mobile by default automatically drops down to 3G access from HSDPA to save on battery-life when the device is not utilizing high amount of mobile internet. I noticed I can easily get back on HSDPA (even for just a few seconds) if I do something like browse the internet or even just update the weather and I can also sustain HSDPA with problems.
I think what you are experiencing is a feature. I haven't noticed any problem with the behavior, in fact I think it works better for me, it uses less battery.

Q: SGS2 call drops and connecting problems

Hi, I have strange problem with my SGS2. While I'm in my apartment I simply can't use it to make phone calls.
Someone calls me, I answer, either by dragging or by pressing home button (I set that option in the call setting menu). But nothing happens, ringing stops, but screen stays the same, showing that someone is calling me, and of course, it isn't connected, no voice is coming through. I can drag answer icon all day long but it won't make it connect. If caller is patient enough it will connect after 30-60 seconds after I tried to answer the call.
Second problem is that if I call someone, or it connects us after those 30-60 seconds, call will simply be dropped after 5-10 seconds.
Signal is fine, 3 or 4 bars, when I'm somewhere else I don't have these issues. Few days ago I got called while I was in underground garage in same building I live in, there were no bars on signal indicator, but phone answered immediately and it didn't drop for those 2-3 minutes I talked. But When I'm in my apartment (I live on the 4th floor, there are no large buildings blocking the signal, and anyway, phone says signal is 3-4 bars...) I'm unable to make or answer calls.
This is from the first day I bought it, at first I thought it's something with network, that they were doing something, since my old HTC Legend had no problems here, but after a month it's the same.
Do android phones have radio "part" in their software? Like older WinMo phones did? I remember my yet older HTC Artemis had so I could flash other radio versions to get better reception and battery life.
Or does someone have better idea? Because I'm all out, warranty is useless since this isn't something that happens everywhere so I can't show "them" it doesn't work...
Firmware is stock, I debranded it from t-mobile to XWKE7, kies recognizes it so I think I did that part OK. But anyway, this problem is from day one, before I reflashed it for the first time.
