Guys here is my situation. I have a Cingular 8525 for some time now I noticed that it was dropping signal and then recovering it I thought it was a radio problem but I changed numerous radios and it didn't fix the issue. Last night I noticed that it wasn't picking up any signal, on turning it on I noticed that I had No GSM I tried the way in the Wiki but I am unable to flash using the radio 1.16 to it I unchecked Allow USB connections but for some reason I cannot flash the radio. I started the phone attempted to flash the phone with several other radios and it just hangs. On rebooting I see NO GSM but when my phone starts up I see it reads the network but I cannot do anything else no calls nothing. Is there another way to flash the radio to my device or is the radio just dead? If so I have another 8525 thats not working can the radio part of it be changed?
Regards
It seems your phone is toggling between 3G and the older GPRS. By default, the 8525 automatically selects 3G if it is available. If you move out of 3G range (considering 3G support nationwide isn't great yet), which will happen often, you will lose signal temporarily and either switch to GPRS or regain a 3G signal. Currently I default my phone to use GPRS just because i can't be bothered with having to deal with dropping signal/calls as often as i used to with the automatic setting. There is a free tool called BandSwitch which can accomplish this for you. The newer version (2.1) is not free but if you can get your hand on the older version which is, it'll work satisfactorily well. I hope this solves your problem.
I had the same problem and nothing worked for me.
Try different solutions posted my various users and see if anytihng works for you.
I think it is a hardware radio problem and probably the only solution is to change the motherboard.
If it is still under warranty - get it done. If not, you are out of luck.
Hi guys, I'm hoping one of you knowledgeable people might be able to help please, I've done a bit of seraching/googling but not really got anywhere...
I've noticed over the last few days that my TD2 keeps losing reception in places where I normally have a very good signal - e.g. the handset will be sat on my desk at work for a while, and when I pick it up to use it to make a call, send a text etc I notice that the network icon on the taskbar at the top is showing an exclamation mark to indicate there is no signal. I have to power off the handset and turn it back on to clear this problem (I've tried going to the comm manager and disabling/enabling 'phone' but when I disable it I cannot re-enable it afterwards).
I was wondering if this is a problem with my handset or the network (T-Mobile UK)?
Anyone got any ideas please?
Device information in case it's needed:
ROM Version: 1.39.405.2 (47382) WWE
ROM Date: 04/07/09
Radio Version: 3.43.25.19
Protocol Version: 61.20t.25.10U
I had the same problem in areas where the 3G signal is weak. I disabled 3G and everything is OK. I also noticed a dramatic increase in battery life.

I get this every 2-3 weeks (known strong signal area, no reception at all indicated), it could a bug in the Radio ROM, perhaps? Updating the Radio ROM might help. But this...

..doesn't sound right. I do this and it clears the problem without restarting the phone.
@ kskar - Sometimes I'm in a good 3G area when this happens (Manchester city centre, UK) and sometimes I'm not (at home), so I don't think this would be causing it.
@ Pete_S - I was wondering if it could be anything to do with the Radio ROM... I also tried turning airplane mode on/off in comm manager, but it usually won't come out of airplane mode either without powering off & back on.
You could also try constraining the phone to operate only in the UK bands (phone settings - Band - GSM(900+1800) + UMTS(900+2100)) and, if you only use 3G, set network type to "WCDMA".
Hi guys/Girls
Hope you can help and point me in the right direction.
I performed a ROM update on my phone earlier today following your extreamly helpful guides.
But now I have a problem the 3G/HSDPA (I dont get any atall), where as normally i would be on HSDPA while sat at my desk in work, now i get a very poor GPRS reception.
I Understand this is something to do with the Radio Version?

What version should I be applying/where should I get it form? And is it just a case of running an EXE like it was with the ROM update (after applying the HSPL, which i have already done).
Thanks in advance for any help you can give Ive found this site extreamly helpfull so far, and I'm sure you can help me out here aswell.

I had the same issue because the o2 ROM sets you up just before Windows launches after a ROM update, or hard reset. The stock ROM is network independent so it doesnt do this.
Anyway, go to Start/Settings/Menu/All Settings/Connections/Connection setup, then just choose UK and O2 respectively.
I hope that helps.

Thanks for the quick reply, but I have tried this, and even downloaded the updated settings (very slowly over GPRS) dosnt seem to have made a differance.
I'm running through Random Radio Versions at the moment trying to find one that works, and provides me with the signal strength i had before. If i find out I will post this info here to help others in the future.
Obviously if someone has already solved this issue please let me know to save me some time
There should be a 3g/GSM switch in the Comm Manager, GSM will be only GPRS and Edge wheras 3g will include 3g and HDSPA. If it isnt there, there is a tweak (either reg edit or a cab file i think), search through the forum and you should find it.

Would this be the same as going into the band settings and configuring them as Auto? Thesrs loads of numbers in here that im not going to even pretend to understand Shed any light on what the UTSM settings should be etc... or should they be left as AUTO?
When setting up a data connection, i only get the option of "Cellular Line (GRPS) and not Cellular Line (GPRS,3G). I assume this is my problem?
Ahhh so confused, I'm on my 3rd Radio version and none of them have made a differamce yet

I am on o2 and everytime I do a rom update I have to switch the 3g on. So that will more than likely be your problem

Without wanting to sound really dumb, or ask a stupid annoying question but how do i do that? My band settings are already set to Auto
Settings tab on Sense, Wireless controls, then you should have a switch that says 3g, in your case it should be off, turn this on. If it isnt there, let us know!

No 3G option, I did have a look for the CAB/Reg tweak, but from looking at it it just changes the band settings from GSM to auto (which mine are already set at) if this is not the case whats the best way of adding this switch?
http://www.ad-grafiska.se/HD2/LEO TWEAKS/Touch X add 3G commmanager.cab
This is from the sense 2.5 tweaks & mods cabs thread, it will add the 3g button. Try and see what happens, if it doesnt work then I will see what settings I have on mine

OK ive installed the CAB (Thanks for linking to it for me was a great help). After restarting my HD2 i now have the option to disable/re-enable 3g.
However (heres the bad news) it was already set to on. Iv switch it off/Back on etc... and i'm still only getting GPRS, with no 3g option under the new connections manager.
The_cool, are you on O2 in the Uk aswell? If you try to set up a new connection can you select Cellular Line (GPRS,3G)? I only get the GPRS option.
What ROM/Radios versions are you using?
If you had the stock O2 rom, flash the radio that came with your phone -
Leo_RADIO_15.26.50.07U_2.04.50_22_2(from HTC ** 1.43)
see the radio thread.
radios are independent, I should be surprised if its that.
have you tried the icon your sim card installs? look in start, probably down the bottom , looks like a sim card and called o2 (or whatever sim you have in) and has one option...get settings?

I am from the UK but I am on T mobile, running topix 1.2 and my radio is the one that came with the offical 1.66 rom which is 2.06.51.07
I am abit confused when you say "with no 3g option under the new connections manager." Testing the switch on mine, when it is off, it says 3g as the heading and the text under is says Change to auto mode. When you turn it on, the phone goes offline for a few seconds and the switch now says 3g as a heading and the text under sayin Change to GSM mode. Your switch should be like this with the switch in the on position. Sorry if I am being patronising but I just want to be clear.
When you talk about celluar line, I am assuming you mean when you try to set up a new connection, this is only for data connections, not for making calls. If I am not mistaken, even if that wasnt set up, it wouldnt stop you from having 3G or H reception, you just wouldnt be able to using the data funtions on the phone until that was set up. But looking at mine, if I edit my connection, the 1st page that comes up is Enter a name for the connection and the then Select a modem. That is on Cellular Line (GPRS) which is greyed out and I still get 3g reception.
usually you will get good GPRS reception, 3g/H can be hit or miss. Try reflashing your radio or try a different one.
Try going to Settings, Connections, Advanced Network and then check that Enable HSDPA/HSUPA is showing in the HSDPA/HSUPA tab. The options on mine are Disable, Enable HSDPA Only and Enable HSDPA/HSUPA.

That only enables or disables HSDPA, even if diasabled you would still get 3g reception but i guess its worth a try.
perhaps the local antenna is having problems or other source of local interference?
I have personally noticed in comparing T-mobile and O2 that in most places T-mob have good to great 3G, whereas O2 is iffier on 3G, but faultless 2G.
I just flashed my sister's Diamond/Ignito with the latest official UK O2 diamond rom and now she only gets gsm and no 3g either. What the heck is going on?
Origional SPL installed and phone still has the same problem.
After speaking to O2 Cust Support it seems there are intermittant Network problems due to upgrades they are performing at the moment on their network. However that dosnt explain why my old SE c905 has full HSDPA when my hTC HD2 as 1 bar GSM or no signal atall using the same sim in the same location (and only the amount of time it takes me to swap over a sim in time differance).
Phone is going back today, as I'v only had it a week.

I'm an expat living in Beijing. Picked up my HD2 a few days ago. The guy flashed the following stuff on it:
os version: 5.2.21889 (21889.5.0.87)
manilla version: 2.1.37889.1
rom version: 2.09.531.4 (81280) WWE
rom date: 2/12/10
radio version: 2.08.50.08_2
protocal version: 15.34.50.07U
I cannot get it to browse the net on China Mobile. I've put in the cmnet/cmnet, i've tried cmwap, i've tried every combination of entering them into the username/pass as well. Nothing works.
I've now put on it something called HTC connection setup, which seems to have pre-set up a lot of those fields. Still doesn't work. (and i can't uninstall this one, it seems)
I've installed a program called datacontroller, where I can manually turn on all the types of data. Still doesn't work.
Is there something wrong with the rom that was flashed onto it?
Is anyone in Beijing?
Thanks everyone for your help!
by the way
By the way - the phone is not the HTC branded model, but it seems on the startup screen, i can see a sort of t-mobile logo (the brand animation is there, but the words t-mobile are removed).
Also, one strange effect from this rom:
I cannot add new locations in the clock.
i had a problem with my data connection on my HD2 the other day, the solution was to make sure you are trying to connect to the right network.
go to comm manager > data connection > advanced tab > select network.
i had to have both option set to "telstra internet" beacuse im in australia, you might just need to set these to the right network selection. though im afraid i cant tell you which is the correct network for your location/network provider.
good luck.
solved
actually i went to that screen - and it turned out that out of all the stuff - it was not set to the right network. none of the instructions i found ever mentioned that particular screen. it needed to be set to something like cmnet, but it was set to one other other ones which I'm not using!
thanks!
Never had any problems when using the HD2 in Shenzhen or HongKong on Chinamobile
but it could be that you have a older simcard that doesn't support your dataconnection.
Good luck.
yeah, i spent about an hour on the phone to my network provider, and after a couple of hours googling for a solution... THEN i found that suggested solution.
glad you got it fixed though.
