(reposted from the Unlock forum, which is NOT where I tried to post it yesterday - things seem a little messed up around here - reply/post often doesn't seem to work without logging out and back in and now this)
Anyway,
4.00.10 T-Mo with their radio stack.
Keep finding it with dots crawling where signal strength should be - reports searching.
Soft-reset, and the signal is great.
Cannot receive calls, or make network connections when it is in this state.
Anybody seeing similar/same behavior ?
I have experienced the same. It seems as though the radio actually stops searching for a signal after some period of time. Either a soft reset or turning the radio off and back on again seems to fix the problem. The upside is that in previous versions it would show a weak signal but could not make or receive calls. At least now I know when it is really not working. Seems to have this problem most often in my home, where TMo service is the worst in my city.

I had that problem too so I switched back to the ATTWS A.20.10 RSU and the problem goes away (well mostly...). Both stacks can have problems with weak signals and acquiring GPRS signals but in my experience the T-Mo one is worse by far. Of course I am an ATTWS subscriber and maybe a T-Mo subscriber would have just the opposite experience.
Been investigating this extensively today.
It seems to be that this situation occurs when the device tries to use the GPRS when it is still searching (as opposed to either with or without signal).
My e-mail was checking every minute - and reliably tripped the unit up moving in low signal areas.
Stopping the e-mail connection and forcing GPRS off (soft-reset or phone off, followed by no IP activity), I could not get the phone to go into this state.
Browsing, and then just leaving the GPRS active, it did not go into this state. Once I put the regular mail check back on, I got it into this state - eventually. Hopefully there will be another radio update before they make this release final!
Nigebj: Brilliant! Thanks for putting in the time to figure that out. It certainly makes sense of my situation. Now to figure out a workaround...
Barjohn: This must be carrier-related. My signal strength and call quality improved with the new TMo RSU vs. the ATTWS RSU, and I am a TMo subscriber.
Each revision of WM2003 and the new RSUs seem to get better. Hopefully the final release will come soon, and these annoying bugs will be aleviated.

It's a darn shame that some of these companies aren't willing to utlilize the very valuable resource that we represent. If they worked with us they would learn about many of their problems beofre they become consumer problems on a wide scale. They could be selective within our community but I have over 30 years of IT experience and software development behind me. When I was doing consulting work I charged $200/hr for my time. Here they could get it for free. If they provided me with more information I and others on this forum could provide them with detailed information on the problems that would ehlpt them put out a better product. Instead, many of these companies get all ego involved and don't want to work with us. I have offered my help to ATTWS and their engineers and I have gotten the same response.
I run some very larger projects. My current project for the Navy is a $20+ million dollar project. If my engineers treat our customers like many of these companies, they would not be on my team very long.
I want as much feedback and help as we can get. It is my engineers job to then filter the feedback and weekout the gems. There are always some gems in there and the effort is worth while. I go so far as to insist that we put customers on the development team so that we have first hand input. We save time and produce a better prodcut as a result.
I'll now step down from my soap box :lol:

Ah but I think they are!
Why would an AT&T employee risk getting fired by releasing (almost certainly) traceable code thru the internet. Or the T-Mobile employee who did the same ?
By doing this totally unofficially they get the feedback (they can read the same as the rest of us), but they incur no wrath if the machine gets trashed (and we've seen how some people get annoyed even when they're explicitly doing something which is not supported - let alone being in a field test for a company).
No, I firmly believe our skills are being leveraged - which is one of the spin-off benefits I believe we'll all realise by ensuring this community stays active.
You have a good point and I hope you are right.
For all those who are mildly paranoid about being monitored how much do we really know about the following: The XDA2 changes hands, is the original owner's info still linked to it; the XDA2 is barred, when using it as a PDA does it still send out signals? if so, can these signals be located? can the XDA2 be used to surf without a sim card, if so, are the signals posted to anyone? Can the XDA2 be unbarred? If it can be, is it hardwired to retain its original ID? Does all this sound like the Matrix ... well it may well be! :roll:
sounds like u got sum good dope

When the radio is switched on the xda sends the imei whether a sim is in place or not, the information of a previous owner is lost once a hard reset is carried out, however some people think that by unclicking permanant save, that the data is lost, well that isnt true because if the next owner switches it back on and you were using the feature before, he will have access to all your data, the only way I found was to delete all contacts, check permanent save, reboot then uncheck it. There is no way known at the moment that is public knowledge that allows you to manipulate imei on xda2. I understand that there are calls from the uk government to have all imei numbers in hardware rather than firmware/software to make it almost impossible to change identity. Just because you are paranoid doesnt mean they arent out to get you. :shock:
Thank you you seem to be THE authority on XDA! You say ""When the radio is switched on the xda sends the imei whether a sim is in place or not"" I am not sure I understand the concept of 'radio' in the xda2. can the radio be switched off/disabled? what signals are sent and how are these managed, by whom? because there is now billing requirement why should this radio signal be monitored? It has been also said that "Paranoia is the belief in a hidden order behind the visible." anon (why do u think he chose to remain anon?)

I was in a security presentation and saw how a secuirty engineer from Motorola was able to pinpoint and triangulate 17 different phones in an auditorium and then go down to each unit and "clone" it for surveillance purposes with a GUI application in his laptop. ( With the users permission for the purpose of the demo!)
If they are showcasing this technology, then I guarantee Big Brother
( NSA and NRO specifically) have the capability in a more advanced form and blend it with Exchelon, key word analysis and the like....
have a look at www.followus.co.uk its excellent we use it to track the kids, ( the more cell sites close by the better the fix) its show us they are at near by to where ever they say they are
Yes, I am aware of that service.
It is a good thing for parents and businesses and is not infringing on privacy because it is consentual and voluntary.
It amazes me to see how many peope think cell phones are not easy to trace or tap because they are mobile!
Having started this thread, I was begining to think no-one cared!
Is it worth pulling together all the intelligence on remote monitoring in one place? The benefit of this will be to know what currently done and if it is at all possible tweak the systems to ensure a modicum of privacy.
There is all sorts of legislation protecting privacy and some ensuring civil liberties. What are the implications of mobile phone contracts, for instance? Do they have a duty of care to protect our privacy is there anything in the contracts that limit their liability in this regard, and if so, why?
oh ... and I don't smoke but I'm told that I don't need to!
I recently moved into a new ‘cell phone death trap’ apartment (apt).
I’ve seen my phone connect, I’m guessing; connect to four different cell towers from my apt. I’ve sat and watched it go from 2 bar E, disconnect, to 1 bar G, disconnect, to no bars 3G, disconnect, and so on….
But here’s the clincher…
Sometimes it will also connect to a full strength edge network, but it indicates it’s roaming by the Triangle icon. Now if I’m on that ‘Triangle” network, my phone works great, meaning I actually can make and receive calls!
But, I’m guessing again, because it shows it is roaming; it also does not like to stay connected to this network. Actually it prefers to switch itself back onto a weak edge network without any signal.
My phone battery doesn’t last more than five hours, NOT TALKING, just in standby because it is constantly switching towers.
At this point I want to throw my Hermes out a window! But I know that wont do any good, because anyone else who come to my apt and has AT&T/Cingular gets the same results.
So here’s my question:
“Can I force my phone to stay on a particular cell tower?”
If so, I love you….
you should re-post over in this thread Daniel's software might be able to solve your problem (or Daniel might have other ideas).
thank you for the suggestion. i tried that and he said, "Sorry nop. It isnt the pourpose of cmp or bs...."
I don't think you can force to a specific tower but you can force to a particular provider:
START/SETTINGS/PHONE/NETWORK/MANUAL
and also select whether you want to force GSM/WCDMA and the GSM/UNTS band:
START/SETTINGS/PHONE/BAND
Maybe by going this route you can lock onto a reasonable signal.
2 other alternatives... Sell the appartment... Buy a landline and donate the Hermes to me

Are you able to change networks?
Are you able to ask your service provider the location of the towers and if they're planning either any upgrades or any more in the area?
If not you may wish to consider the first point, changing service providers.
I know what a pain it can be to have little or no service when needed. Personally, here in the UK, I'm on Orange. Where I lived in Wales it was either Orange or Vodafone that has a decent signal. When I'm out and about with work those are the two popular towers with o2 creeping up and some others too, but for the most part those are the strongest.
I don't, I'm sorry, have any better advice for you. Apart from leave your Hermes on charge when you're home near a window (safely) and carry a bluetooth earpeice around instead Good Luck with your Valiant Quest

I've tried this method as well and it does not help. apparently both the good and the band networks all fall under GSM(900+1800)+UMTS(2100). The other two band options never find a network.

Thank you for your suggestions. Unfortuantly im locked in a 2yr contract, thats how ****ty american cell phone companies do things. Plus, the better providers in the area dont use SIM cards (ie. Sprint/Verizon), so that would mean bye bye Hermes.
Ill will go by the Cingular store and ask about the possible service upgrade, but those fools dont really know whats what, thats why im on xda-dev!
I like the bluetooth idea, ill try find a "sweet spot" in the apt and try that method. Thanks again!
"I have dream..."
My idea just seems possible, however i cant program so who am i too.....
The idea of having blocked cell id numbers. If i could FieldTest or somehow extract the cell ids from the towers i dont want, then create a file that the phone checks against before joining a tower.....
I dont know, just a dream i suppose...
In both cases (roaming and not) are you registered in same operator?
If you're having a difficult time maintaining solid cellular reception, you might want to consider buying an external antenna. Refer to my post here regarding an antenna that can be purchased from Radio Shack. The antenna is now on clearance for $20 and the pigtail is $10. This may or may not help depending upon your location in relation to the towers, but if you try it out, let me know how it works.
Cheers
Yeah, I'm on an 18 month contract... But I'm about 8 months in now
You might even be able to get bluetooth repeaters once you find your, ahem, sweet spot

i believe so. the only reason i think it's roaming is because of the Triangle icon. But my SIM is only authorized for one operator, Cingular.
is there a better way to check?
Thank you very much Daniel!

Call your closest Radio Shack and ask if they have either of those catalog numbers in stock. Worst case scenario is that they won't, however they can check the districts perpetual stock and see how many are available, and if you ask nicely, they can have the antenna and pigtail shipped to their store so you don't have to run all over creation just to get it.
...An even worst case scenario would be if you didn't live in the US or didn't have any Radio Shacks close by.. however I might know of someone who could use their employee discount to cover shipping costs Let me know if you have any questions.

Taze,
I would also recommend that you try one of Daniel's applications - he is working on Comm Manager Pro but I think that Bandswitch will probably help you. I find similar problems to those you describe at work here in the UK with T-Mobile and my battery would often run low even during a day at work. The problem appears to have been caused by the Vario II (Hermes) spending all day jumping back and forward between networks whilst hunting for the best signal. Although the Bandswitch application (very small footprint) will not increase the signal you may find that forcing the phone to operate in a particular band helps - this is very easily achieved via the Bandswitch interface rather than going into settings each time. I now regularly switch to GSM each day when I get to work and it has solved my battery run-down issue completely!
Comm Manager Pro does much the same and more. It allows you to define a location (according to Cell ID and LAC Code) from which you can set the CMP application to (amongst other functions) switch to a particular band - or even turn the phone off).
Given what you have said this may not help but I would certainly give it a go. Good luck.
Regards

im going to try bandswitch today and see how it works. thank you for the suggestion!
i wish daniel could add the feature of blocked, preferred, of locked Cell ID's. that would be worth a good amount of money to me....
Hi.
I would like to help you.... I can detect cells and lac but I cant force radio hardware to attach on a particular cell. This a task for Radio ROM. The only posibility (maybe) would be if the operator names are diferent. Could you go to settings a search for operators? Maybe your operator has different name in roaming than non roaming. In that case It would be easy to help you....
Oooo if FieldTest were a controllable application....
Ok what I’ve discovered so far after watching FieldTest for about an hour.
The Good Connection -
LAC 0020
MNC/MCC 31017
NCELL INFO1 700-80 dbm <---- (at least four out of six NCELL maintain a steady 700-80dbm, often all six NCELL)
NCELL INFO2 700-80 dbm
NCELL INFO3 700-80 dbm
NCELL INFO4 700-80 dbm
NCELL INFO5 700-80 dbm
NCELL INFO6 700-80 dbm
BAND 2CS
CHANNEL 1:CCCH (stays, doesn’t change)
The Bad Connection
LAC d6ef
MNC/MCC 31380
NCELL INFO1 140-100 dbm
NCELL INFO2 140-100 dbm <---- (i get two NCELL at the most 140 each, rarely four NCELL, never more)
NCELL INFO3 0
NCELL INFO4 0
NCELL INFO5 0
NCELL INFO6 0
BAND 3:850 (once I saw it switch to PCS on this same MNC)
CHANNEL 1:CCCH/0:BCCH/255<UNKNOWN> (switches between these quite frequently)
So what I’ve interpreted from all that is.
Well I’ve confirmed my ****ty connection. Even though the phone often shows two bars, I can’t make or receive calls. Based on the NCELL db numbers and the constant channel changing, that **** just don’t work.
Most importantly, the phone is always trying to switch to the highest possible band. Because PCS is a lower band than GSM 850, my phone won’t stay on the PCS connection.
O yes, another discovery is, in WM6, if you are connected to a PCS band network, it displays the Triangle icon as if you are roaming but in fact it is not roaming.
So Daniel since you seem to be the best chance for a better life [for my Hermes]:
I need a way to force band selection beyond just GSM and UMTS.
I tried BandSwitch and it does not work for me because all my available connections fall under GSM.
And even beyond that I’d like to be able to force MNC’s, as I believe they are the specific network number.
Or can I block a LAC?
In settings, I only have one operator, Cingular, “Home of the most dropped calls.”
Hi.
I undestand perfectly your frustration and I will try to do what I can althought It doesnt seem easy thing because there isnt any(known) api to manage Radio Rom. Fieldtest is OEM dependent and I imagine It only works for only one manufacturer of radio hardware chip.
Ok, first try. If you start radio phone 10 times....
1) how many times your phone register to roaming (and wished) network?
2) If registed to roaming network, how much time (aprox) stays on it before register to bad cells?.
Why? well ,CMP executes actions when you enter on some place (compound by cells and lacs). You could create a place with your hated cells and then associate the action "reset radio" when registed to those cells (or lacs). In this way if your device falls into bad cells it would be resetted (only radio, not phone) until registed to good cells...
Only an idea....
Dani
If you can determine the direction of the "bad" towers, try lining your walls with lead sheets to block their signals and letting you connect to a prefered tower.

good luck with fbi, mi5 and cia.
Now i dont think that it is possible, but i dont understand why people find this request so funny?
There are plenty of tools that measure radiation. The radiation of a phone in use should be much higher than one not in use or one using bluetooth. Not sure about wifi though...
Anyway, to have this type of measurement in the phone is maybe hard/impossible to develop given the way phones are built. But the idea of something measuring radiation is nothing new and these devices can be bought at many places (most for corporate or media usage). Now if you could just set the frequecy to monitor and a specified minimum threshold you should be there
But as previously mentioned... dont know if this is actually possible to do with a phone.

while this is very possible depending on the extent of the intend program this could be VERY illegal considering that the US goverment(idk about laws in other countries) got in trouble for monitoring phone calls.
If the program was meant to only detect GSM activity it is probable possible but at the same time there would be no accurate way to determine if the active phone was in your room or down the hall unless you knew which phone was where and what its info was. But in doing that im pretty sure you have already breakin a few laws lol.
If you are worried about phone activity im fairly positive there are phone jammers which block phone calls for a certain distance around the device. Though i do not know the laws around this.
I don't know how you'd do it with the phone...but there are DIY circuits that you can find online to make one with a 555 timer chip and a few resistors and capacitors. I did the same thing as a final project for an electronics class I took last year.
Just google "Cell Phone Call Detector circuit". It lights up an LED when it detects a call.
hello!
i don't know of a program to use with your phone, but i did a quick search on the net and found this for example: http://www.globalgadgetuk.com/detector.htm
maybe that can help you?
Here is your solution:

and here is one for GPS:

try to use a big speaker so you can hear if somebody uses the telephone
Well...
this is not really the thing you need.
Proof of GSM usage around you cannot be provided to 3rd party (your device). The reason is hidden in the GSM1.1 standard.
To monitor the activity of the radio devices surrounding you you should need to download statistics from the closest BTS units which is actually hard enough and the Diamond's CPU is not able to break the provider encryption in realtime (trust me. i've tried it hard enough
Back in the days we faced similar problem. From the other side, I was the student
The principal of our high school designed an emitter of 900/1800MHz signal and had it equipped with a clocking device. For that reason we could not use our cell phones during class... for two days (yeah, nothing is impossible!)
The question you should ask is. Do I want to monitor cellular activity or I need to ban the usage of mobile devices in the range of XY meters around me.
If the answer of the second question is positive jut get a pal of yours who knows something about solidering and within a few dolars you have the item you need.
So my T-Mobile HD2 is freezing up completely (necessitating battery pull) within a minute or two of turning on and using mobile data. Like the title says, it's happening on both ICS and Gingerbread ROMS.
HSPL 2.08
Radio 2.15.50.14
MAGLDR 1.13
CWM 3.0.0.5
Current ROM: Langthang's HD2 NDT MIUI STABLE VERSION 6.0
(http://forum.xda-developers.com/showthread.php?t=1010498)
Previous ROM: NexusHD2-ICS-CM9-HWA_V2.0
(http://forum.xda-developers.com/showthread.php?t=1434860)
Both ROMS run well (esp. the current one) except for the mobile data.
I've had the phone for about 16 months. When I first got it in the USA, I didn't trust myself to flash it to Android for the first time, so I had someone else knowledgeable put a Froyo ROM on it. So I can't tell you what version of HSPL he used to flash 2.08 to it. The phone worked fine (except for occasional overheating--it's an HD2, right?), including mobile data. This was in the USA.
Then I moved to Thailand where I didn't use mobile data at all for a long time. Last month I flashed over the old Froyo with the two ROMS (clean install) listed above and have started using mobile data for the first time in Thailand and am now noticing this problem.
More info:
1. Turning mobile data on and not actually using it actively (i.e. just letting whatever few Google things auto-sync in the background) will have it freezing within half an hour. Using it actively will have it freezing in 1-2 minutes.
2. Using a CPU governor (No-frills CPU control) set to the most extreme (“powersave”) keeps it from freezing up the phone for only a little bit longer than having it set to “performance,” so I don’t see the point in using that as a workaround.
I can guess what most people are going to say at this point: dude, you got one of the HD2′s with a hardware overheating problem; sorry, buy a new phone. Well, can’t afford to for a couple months so I’ve been trying to solve it in other ways. And anyway, I’ve stress-tested it with everything but mobile data (heavy use of camera, playing music, videos, and wifi) and no problems. Sure, it sometimes gets warm and might crash very occasionally...but no problems I can't live with.
So why in the name of all that is holy does using mobile data ALWAYS freeze it?
1. Would flashing a different radio conceivably help? Maybe because a different radio would work better with my carrier here in Thailand? (I know, you have to be careful that your radio is compatible with your ROM, else you brick phone. Also, I don't want to flash radio unless I absolutely have to because it's dangerous-ish).
2. Is HSPL version an issue?
3. Could it be my APN settings? Entering the info (minus the DNS stuff; don't know where that goes) from the following site (http://www.flexispy.com/globalapn.htm) stops mobile data from working at all. My carrier is AIS in Thailand.
Anyone who can help me, it's much appreciated. Thanks in advance!
HSPL fine & radio should be ok but was not best for me in asia but not due to overheating of device ...
Do the fridge test, keep it in fridge for 1hr in plastic bag to protect from moisture then activate data & see how it performs, keep it in fridge as much as possible or cool as possible with aircon, fan or ice bed ...
If you get lot longer times before freezing you can be 100% sure it related to heat & mainboard bga failure under heat.
Thailand is very hot and running temps of phones & notebooks are a lot higher here so a weakness is more easily reached ...
As you say you already have experienced overheating I would assume your mainboard is a bit more sensative to heat than most, we have over 20 HD2s in company use & in over 2yrs only 1 handset has had freezing issues & was mainboard BGA issue & new mainboard fixed it.
I would assume the the functioning of data produces more heat in term of cpu, radio stack & battery in a way that heat soaks the device to failure, I would of thought HQ video playback & heavy wifi use could see same fault so some more stress testing may be an idea too.
you on AIS 3G ?
You could try radio in my signature, I have used it in Thailand & asia pacific with great success so maybe worth a try !
I've done a little fridge testing and it does seem able to function on mobile data without freezing up. So obviously my phone's more sensitive than average to overheating (and also because of Thailand's heat), but I still wonder if using a different radio would work better and maybe not push my phone "over the edge."
One reason I still think there might be something wrong with the radio version is that I can never get 3G (only EDGE), even in places where I absolutely KNOW there's coverage. The other reason that makes me suspect the radio is the stress-testing I was talking about before. I tried really hard to make my phone overheat with a lot of processor-intensive stuff and I couldn't.
I really don't want to beat a dead horse, but does anyone else have any opinions or ideas before I mess with flashing a different radio?
P.S. Thanks for the link to your radio, Mister B.

IMO Mr. B is right about overheating motherboard, but couldn't harm anyone to flash another radio version.
Even I'm reservated on this, I wish you GOOD LUCK!
No 3G: Is 3g enabled in phone settings ?, is 3G enabled on your AIS sim card account ?
Trying another radio will do no harm & may help as might using the least resource hungry ROMs ... Android is a power hungry bulk of an OS & most mainboard faults only appear on Android or are worse on android ...
I have same TMOUS HD2 & 3G works fine here so no issues with phone Radios bands as many worry about ...
Mister B,
After writing that huge long post...I might be an idiot.
3g was enabled in my Android settings, but I didn't know it had to be enabled on the sim card. I'll go to a phone shop tomorrow and ask them about it.
Thanks everyone for their advice.
I not know who the idiot but worth checking as I believe if not buying a sim packaged as 3G you do not get 3G without getting account upgrade .
Confirmation either way will be useful ...
Unfortunately AIS website is a very good example on how to have a huge amount of content & over complex account types but absolutely no easy to find useful clear facts ...
Mister B,
1. Went to a phone shop and explained my problem. The guy there told me that he didn't think my phone was compatible with AIS' 3G band...but you have working 3G in Thailand with a T-Mobile HD2. Is your carrier TOT Mobile? Xda won't let me post outside links yet because I'm new, but I looked up the specs on the T-Mobile HD2 and on Thailand's mobile phone bands and it looks like the only carrier the T-Mobile HD2 can use 3g on is TOT Mobile (only carrier with either a 1700 or 2100 band).
2. Also, when I first got my SIM card here last year, I got a regular one, not a 3G one. The way I signed up for 3G was just by looking up and texting a code to AIS to subscribe to 3G service. I thought that was all I had to do. It seemed to work, except for only being able to get 2G. (I'm in Chiang Mai, and I know AIS has good 3G coverage here; I've experimented using my phone all over the city, but no 3G). So it looks like you're right in your last post about needing a 3G SIM card or an account upgrade.
Thanks again for your all your help. Would you mind confirming that your carrier is actually TOT Mobile? It would help me troubleshoot.
I use TOT for 3G (iKool) & DTAC for 2G Edge.
I thought AIS had license for 2100MHz 3G but if on 900MHz then will not work on AIS until upgrade there network.
Thailands 3G is a bit of a bodge effort until licensing is approved.
I would assume your current sim is not at fault & if you activated 3G via sms code it should be 3G active & just the current band being the limitation ...
How I wish 3 network would come to Thailand, their HK network is superb ...
