Hi all, my radio is 2.06.51. 07 and my rom is the 1.66 wwe.

What is the latest radio for me and is there any benefits to flashing it? thanks
[HD2 General] petersm:
Where can i find 2.10.50.28_2 or 2.11.50?I am having the same problem with Vodafone.

Tried 2.10.50.08_2 but it did not work(from radio topic) Also tried Leo_RADIO_2.07.50.27_2 and Leo_RADIO_2.08.50.05. both ineffective. Only radio I found with .50 is 2.09.50.29_2 which I will try later this day.

I'd realy apreciate it if someone could point me to 2.10.50.28_2 and 2.11.50!

Thanks!

I have tried a lot of radios and always have the same connection loses so not sure if it is radio related to be honest.
[HD2 General] petersm:
but do u know where to get those radios?

could it be rom related?
[HD2 General] reijkelhof:
It was the solution for some people in this thread, as well as the solution to my own connection problems.

All I did was flash hspl and that radio rom, and it's been working flawlessly since.

It's the combination of Rom and Radio Rom.

I would never have flashed if I did not have problems, so the benefits in my case were solving a problem.

But I read it can also make a difference in signal strength and battery drain.

Here is the radio rom thread:

http://xdaforums.com/showthread.php?t=611787

though I found the Radio 2.10.50.28_2 either in this 'HD2 Loses web connection?' thread, or by doing a forum search.

Not sure which.

I eventually found the radio with google. pointed me to xda lol, must have misstyped at the search because initially I couldn't find it.

However, these radios weren't the sollution. So i reverted back to stock(1.72) with 1.66 spl and stock radio and voila, internet connection works like a charm.

Only thing is that I don't want stock rom because it is buggy, slow, freezing. I hate it. NRG rom is what I am used to, much smoother and faster. NRG should work at HTC.

I tried WM longlife and it did help, but I did not find it ideal.. However, If that's what it takes to work with a custom rom then so be it, because with stock rom the phone is useless!
[HD2 General] reijkelhof:
solved

This should be my last post/update in this thread and on this issue.

My problems were 100% fixed by flashing radio, have not lost the data connection once since.
[HD2 General] dhmtbykr:
fixed

After weeks of dealing with disconnects and switching airplane mode on/off to reconnect its finally fixed.

I flashed 2.10.50.28_2 radio and havent disconnected once over the last week, what a breath of fresh air.

BTW I am using WWE 1.66.707.1 (76641) rom for anyone trying to match a working radio/rom combo.
[HD2 General] petersm:
I can confirm this too!

I'm realy relieved!
[HD2 General] teddmf:

I can confirm, after 2 weeks testing, radio ROM 2.10.50.28_2 solves these problems completely for me too!

After testing all newer radio's (even the newest 2.12.50 series) this is the most recent one for me that works. It's a shame that newer ones do not work for some users. It seems to be ROM-related, but maybe also devicebuilt related?
[HD2 General] mrcreativity:
I dont know how relevant it is but facing a similar problem with my kaiser.

I'm using a custom rom and have tried various hardspl and radio combos with the same results.

I loose network connection when i wake up in the morning. The thing is that the taskbar shows all bars but the data connection shows no connection available. I cant receive or make calls.

Turning the raio off and then on again solves the problem. I dont know if its a problem with the ROM because i never had this issue when i was on Stock radio and rom.

[HD2 General] reijkelhof:
You should think about updating your Rom version, at least to 1.66 then try again, and if you still have problems, flash the specific radio advised in this thread as 'the solution'.
[HD2 General] NYLimited:
I updated to the radio shown below about 2 weeks ago. since that time ZERO connectivity problems!
[HD2 General] Cret:
Loads of people have suggested this one now so I downloaded it but I can't flash this for some reason. I forget the exact error given by RUU but it was something to do with error 238 I think - cannot read or open the rom.

Whereas I downloaded one of the other ones mentioned on this page and that flashed fine, but hasn't helped.

I've downloaded Radio 2.10.50.28_2 twice now and it did the same thing both times.

Can anyone help suggest what might be preventing this one from working for me?

I really want to try it since it's helped for so many of you!

Cheers!
[HD2 General] Cret:
Actually the problem is not a read error as I thought.

What happens when I try to flash 2.10.50.28_2 is that RUU tells me it's about to install 2.00.911.1 and if I allow it then it basically seems to do a full hard reset and I have to install everything again.

See:

Anyone know why this is happening? There's ONLY 1 radio file in the same folder as RUU, and it's the one unzipped from the 2.10.50.28_2 rar file so I don't understand?
[HD2 General] allstarted:
It can work properly

I had problems with disconnecting data too. Really annoying, but I guess I solved it. It was a little manual work, but with the settings from listed on the website of my provider (Vodafone NL) it looks like everything is working.

For Vodafone NL the proxies aren't properly setup, just like the WAP proxy. For me it works, but maybe someone can try this too, so this theory can be approved working (or not).

My ROM - Energy 22 juli CHT

Radio 2.12.50.08_2

HSPL 1.66
[HD2 General] reijkelhof:
I'd love to hear from you again in a few days to see if you did solve it that way.

You'd be the first.
[HD2 General] teddmf:
When I flashed this radio (a while ago) I think it reported 2.00.911.1 too. Maybe the MIRI ROM is not compatible? I don't know. I had ROM 1.66 on mine.
[HD2 General] allstarted:
Till now, still no glitches =) Hopefully it will stay this way.

UPDATE 25.07: It's still working without glitches. Data connection still works after 72hrs. Guess the problem is in the proxy settings from the APN list.

instructions

can someone please explain to me how to update the radio version in my HD2.. i cant seem to find the rom update utility and have no clue how do this update.. my data connection keeps turning itself off and its really annoying..
[HD2 General] jfarhat:
if you want to update your radio, this is how to accomplish that task:

1) determine which radio you want to use. I am on T-Mobile US and just updated to 2.12.50.02_2 and I did not update the Rilphone.dll file, I am using the one that came with the phone. You can choose and download the one you want from a list in the following Link:

http://xdaforums.com/showthread.php?t=611787 (read this thread, very easy to follow directions and great information on it)

2) as it states on the above link: Installing:

For installing a RADIO ROM you need HardSPL installed to your device.

Rename the extracted radio file to "RUU_Signed.nbh" (without the " ") and flash with the CustomRUU (put the new renamed radio file into the folder that has the extracted CustomRUU life): it won't hardreset your device. Then just connect your HD2 to your usb sync cable and run the CustomRUU file, it will do the rest just like flashing the ROM, but quicker.

now which radio to use is kind of a crap shot, it will depend on your area, coverage...etc... As the thread mentions, don't try to change the Rilphone.dll unless you have issues with your radio. I have never had to change a Rilphone.dll file. If you are on T-Mobile US and depending on what ROM you are using (I'm using Energy ROM) I would go with the 2.12.50.2_2. But if you are using another custom ROM, I would ask the chef what radio he recommands and has been tested with his ROM. Good luck

comm registry setting

hey i was looking around and found this post

Ok, so this is one thing that has really bugged me since I got my SCH-i760. I will connect it to the internet and check my email, or look at something online such as the weather or google maps, and close it down and continue on my way. But what I forgot was the fact that I didn’t manually shut off the data connection and for the rest of the day it has eaten my battery life alive! After a while I found alittle program called “BandSwitch” but even it was not free and only a trial of the program. So last night I decided to do some digging since I couldn’t sleep!

After about an hour of hunting around I was able to dig up a very cool registry edit for my phone (and any phone using wm5 or 6) that simply changes one value in the registry to turn on this auto disconnect idle data connections feature. Below are links to the .CAB files to change it for you as well as what to do if you want to edit the registry yourself.

HKEY_LOCAL_MACHINE\Comm\ConnMgr\Planner\Settings\

SuspendResume = GPRS_bye_if_device_off

CacheTime = xxx (where xxx are seconds before auto disconnect, for me the best value is 60)B][/B]

Now i went into my reg and instead of xxx there it says ~GPRS!. i have been having this data disconnect problem and was wondering if anyone out there smarter than me about this stuff knew if maybe this has something to do with the data connection dropping all the time..???? thoughts anyone.. i know that this post is not for a HD2 but its still wm6..

oh and i know that this guys was trying to stop his data connection but maybe if the reg key in my phone read "xxx" instead of "~GPRS!" maybe that would stop if from disconnecting itself..
[HD2 General] Niels-je:
I had troubles with my data connection on my HD2, just as others described.

When connected to Vodafone (Vodafone live!, in the Netherlands) and after a while not using my HD2, it wasn't possible to use the data connection anymore. Allthough it was still present.

I've tried all different settings as mentioned in this thread and on other forums. Nothing worked. Only after disabling my data connection and then reconnecting, I was able to use my connection again. Frustrating!

BUT, since I've updated my RADIO ROM the data connection keeps working!

I've gone from radio rom 2.06 to 2.12 and am using the stock rom (1.66).
[HD2 General] yafibo:
Just to add my two cents to the matter.

Situation: I installed and used "no-data-in-roaming"-app whilst travelling abroad; on arrival back home: serious data connection problems (which I did not have before).

What solved it for me: uninstalling the "no-data-in-roaming"-app. (Tried a lot of different approaches, nothing worked, when suddenly it occurred to me that the difference to my HD2-configuration between leaving and coming back home, was this app. I'd say my connection is back to its regular stability).

I assume the No-data-in-roaming app alters something in the registry. Perhaps this is relevant for solving (some of) the problems?

cheers.
[HD2 General] medcina:
Fixed my issue

After reading yafibo's comment regarding the roaming app, I decided that perhaps the roaming settings on the phone itself are to blame. I had originally checked all options to enable data while roaming since I figured I don't pay for roaming anyway and have had all kinds of problems with data drops. It had gotten particularly bad in recent weeks. Two days ago I went through all the options pages again and unchecked (which is how the phone comes) all roaming options and rebooted and the phone has been rock solid since. Not a single time has the connection dropped and I've tethered to my laptop for hours without issues. Before, I would get hangs even while tethered and would have to wait minutes sometimes for it to work again. My phone also checks several POP accounts every 5 minutes and is connected to both an Exchange server and Hotmail account (set to deliver as they arrive) and all my emails arrive within 10 seconds of it arriving into my account (much faster than 10 seconds if I'm on 3G or faster).

Might be worth a try for some.
[HD2 General] jfarhat:
So if I understood you correctly...you unchecked all the roaming options (so your phone will not connect or attempt to connect to data while roaming). Now, if that is correct and it has fixed the dropped data connection issue, then it is great.....only while you are in your home area. But, what happens when you are actually roaming?? Will it still attempt to connect to a data connect or will it just not even show you have any towers available?

I am on a national plan so I don't pay for any roaming, but I do travel a lot. I'm not sure if any other carriers' towers would be seen as roaming if you are on a national "no roaming" plan.

I became so frustrated with the dropped data connection issue and the slow down of the ROM with T-Mobile's "updated" ROM, that I just flashed a custom ROM (Energy ROM) and I have not had any data connection issues. I think almost all the custom ROMs have firgured out how to fix this issue and you will not experience it with a custom ROM. I highly recommend going that route vs. disabling roaming features. Also, keep in mind that T-Mobile has stated that they will be releasing another ROM update (no date given) that will re-address this issue along with the slow down/sluggishness experienced from their first updated ROM, plus other known issues. It may be worth waiting and trying out that new T-Mobile ROM when it is released (if you feel you must have an official carrier ROM on your device). But for me, personally...I could never go back to the official ROM...NRG has spoiled me too much with his great custom ROMS...I truly make very little changes to his ROM version (I just like to change the SMS/MMS client to the HTC version by Pyrorob - more eye candy and enjoyable to use in my opinion). Other than that, I don't change a single thing.
[HD2 General] medcina:
Sorry it took me so long to respond.

I have a national plan and don't pay roaming either and have yet to find my phone "roaming" regardless of where I've been. I've even been to the boonies on mountain tops and the phone and data have worked fine (assuming I've had a signal). No idea what constitutes roaming but I have yet to find my phone attempting to do so. Still having zero issues with the data connection since unchecking all roaming options.
[HD2 General] elmojh:
I have this same problem too; i am using omega rom for my U.S. HD2... with Skinny android rom (latest version). still trying to find out how i can fix this data / 3G drop. it's terrible.

did not have this problem earlier when i was using chucky rom + mattc desire setup thou.

weird!!!
[HD2 General] reijkelhof:
The problem is caused by a bad combination of RoM and Radio.

Flashing a more compatible radio fixed it for me.
[HD2 General] DOUGRDZ:
lost data connection , problem solved for me.

I was getting my data connection lost too many times in a day.... so I updated my radio to 2.15.50.14 and all went smooth.

My emails now get to my inbox as soon as they arrive to my hotmail ( push activated of course ) and I have my data connection ON always.

So nice, I was kind of frustrated.

I have intalled on my HD2 the Kumar´s HD2 Touch Prem ESN ROM ( Spanish ) V 5.2.23145
[HD2 General] stefanov07:
OK hope I'll help, I had the same issue, HD2 has a problem with automatick switching between WCDMA(3G) and GSM. Just go to Wireless controles/phone/Band and change it from auto to WCDMA, so it will have 3G (G) all the time, only if its very very low signal will go to Edge (E)

The clock is ticking....:rolleyes:
[HD2 General] antaed:

I also renamed my connection to "internet" 2 hours ago and the connection it is stable on HSDPA ever since. It never switched between H and 3G as it used to do before. I'm very happy :) !
[HD2 General] cbeenhackker:
Switching is not the problem... better to have HSDPA..then no connection at all...
[HD2 General] CHIP STAXMAN:
+1

I'll be sitting here with full bars and H reception. Then BANG there goes the connection. Despite me not moving and the phone still claiming the same reception.

As a lot of others do, I on-off the data connection and it SOMETIMES comes back straight away. Otherwise it's a 2-5 min wait while I keep trying till it reconnects.

[HD2 General] antaed:
From bad to worst

Renaming to "internet" has an influence for sure but it doesn't solve the problem:

- the phone is stable on H but sometimes it still refuses to connect to the internet

- the battery drains very fast (35% overnight) and the phone may freeze in sleep mode

See my other post for details:

showthread.php?p=5416460#post5416460
[HD2 General] CHIP STAXMAN:
I've been testing the renaming of the connection to 'internet' for the last 2 hours. No change. It is still dropping connection all the time despite me lying here in bed with full bar reception, not moving.

The phone is constantly dancing between 3 and H as well. Don't know if that's normal or what.
[HD2 General] Towserspvm2000:
I get that all the time, and dropping down to G too, on my Touch Diamond on Tmobile. I think it's either the network provider responsible, or Windows Mobile software/HTC devices.

I reflashed to stock 1.48 wwe rom the other day and applied all hotfixes including the htc radio update (2.06.51.07) and it's been okay ever since.

The phone's more or less stable on 3g and switches to hsdpa when I connect to the internet or other data-services. Before it would refuse to switch to hsdpa and I'd need to reset data or reboot the phone.

I'm running all the tweaks and apps I was before, so I assume it's the new radio that might of fixed it.

I updated to the new 1.66 ROM from HTC earlier today. I've already had the web connection problem twice! But now it's even worse than it was before, because when I try to disable the data connection comm manager freezes. I can't close it from the task manager either. The only way to get the connection back is to restart the phone...

Hello,

I have had this problem too for a while. I just resolved this same issue on my HD2.

1. I have deleted ALL mij connections in my Connection settings.

2. I did NOT use the Connection Wizard to restore my provider settings but I manualy restored the Connection Settings given by my provider.

* Its a bit more work this way but it resolved my Connection problems for more then 2 weeks now :D

I hope this helps!

[HD2 General] The_Rick:
Had this problem today morning for the first time.. Browsers work but weather updates still do not. Sometimes i get an error message ("problem with data connection"), sometimes it just doesn't update anything.

Strange is, disabling and re-enabling data connection in comm manager does NOT solve.. still weather updates are not possible... i'm on Swisscom network

In the same time, as this problem occured for the first time today, i had a problem with sms... my sis has also a hd2 and had the same probs.. she was writing me sms, but i received them all together after a while... same to her..

And as i wrote her, i didn't see my outgoing sms (in conversation-mode), just her (older) sms.. after a while, i received all her new sms and after that conversation mode worked fine again.... she said also she couldn't write me trough "answering" and had to write a "new message", but i'm not sure for that, because i wrote her via "answering" and via "new message", i think both worked... (though i didn't seen outgoing sms in conversation mode)

in classical mode i saw my sent sms but sms that i sent a few days ago were on the top of the list (in "sent items") while today mornigs sms were strangely arranged in the middle of the list...

also this mornig i missed a call, i received notification "missed call" but going into calls screen there were no new calls....

Thougt it was a network problem but ....
