? Porting and how it works on VZW's network - Droid Eris Android Development

I just purchased a network range extender because I apparently purchased a lead bunker for a home and would like to enjoy making phone calls from with in 50ft. of the front door. After getting it setup I realized over the week that, correct me if I am wrong, Hero ported ROMs will not work with it. I have tried ZenEXP v7, Alyous11 and 12, and CE all will not get more than 2 bars in certain places just as it did before the range extender. I have used Senseless and EE and full bars every where.
Sure I know it's like the Dr.'s says if it hurts don't do that but I am partial to one and even donated because of his work. Not equating donating to make it work either just saying I found a ROM I want. Is there something in build.prop or other Identifying flags in the ROM's that cause this issue? I do know that a range extender will not work with a hybrid PRL both the store rep and the 611 tech stated that. I had to be taken off of it when I bought it but I didn't flash the PRL so I assumed that it was already done when the ROM was ported or part of the build. I have done *228 with no avail to make signal any better.
Sorry to ramble just wanted to get all the info out you may want to know. Maybe you know about this and there is no fix or it is new but thanks for all of the Dev's work.

Similar to certain Verizon-only apps like NFL Mobile not working on ported ROMs. No biggie ... until September rolls around and football kicks in.

Which range extender?

My limited understanding on range extenders is that they simply extend frequency bands. I use one with a yagi pointed to the tower so my phone works in my house.
I know where i live Verizon use the 800MHZ band. You may either need a dual band extender (800/1900) or figure out what band is being used in your location. The ROM seems to be irrelevant from the radio side as I am pretty sure that flashing a custom ROM will not effect the flashed radio.
On another note, "bars" is about the worst way to judge signal. Look at the signal strength in the about phone screen.
good luck.

From what explanation I was given the extender does operate on these frequencies but has to communicate with Verizon via Network connection. It has a GPS receiver for E911 and the voice/data bands are isolated to just my house it isn't "truly" taking what is broadcasted from the tower and amplifying it it is sudo VoIPing the calls. Crappy thing is it is limited to three calls and a dedicated 4th 911 line only.
It is a dual 800 (voice) 1900(data) extender. I totally agree with you that it isn't the ROM it is the radio that does all the work for connection. I guess the real question is when you have a ported ROM how does it show on the network? A Sprint phone roam hopping or a Verizon phone? In the management portal for the extender it can be set to either allow any verizon customer with in range access or to manage and give up to 50 Verizon numbers priority over any other Verizon phone access to use the extender.
I am just making sure I don't waste $200 and it is something stupid I am doing.

So I looked up the product I think you have and I fear you may be out of luck. You have a femtocell which is not a network extender in the true sense of the word but rather a mini cell tower which uses your internet connection to route calls via the Verizon network and broadcasts a cell signal for use in your home.
I hate to be “that guy” but you may be better off returning the femtocell if possible and buying a true extender. The range is more limited, probably 10 – 20 feet from the base station, but you will also be able to use it with any carrier on the same frequency and the ROM you run will be completely irrelevant. Dual band ones are more expensive but finding the band that is in use at your home is fairly easy with antenna search. A true repeater will also enable others to use their cell phone is your house as well as allow 3G traffic.
Be aware it requires running some wires and placing an antenna in a existing spot that gets signal, usually near a window or possibly in attic space or even mounted outside.
best of luck.

Thanks for the help

Ok so no you can't add EPST.apk for the ## functions like the eris on a Ported Hero Rom. This was the issue because I couldn't *228 for an option 2 to change the PRL.
Well a combination of stupidity and not listening to the options to realize option 1 really doesn't change anything, and totally hosing up the method of nand backing up my wanted Rom and then wiping Fact Data and Dalvik then flashing an Eris Rom and updating the PRL and then wipeing dalvik and restoring the backup.
So thanks to all of you who gave advice and entertained my insaine problem I created.
If a Mod could Delete this so we can keep the forum clean that would be great.

I was on Ic3 Rom and using the old version of NFL Mobile worked, after upgrading it said that NFL mobile was for Verizon users only. I uninstalled the upgraded version and re-installed the older version I saved, works great.

Boot into Recovery. Make a NAND backup of your current ROM. Flash Ivan's Eris_Official (or ANY other Eris-based ROM).
Do your *228, (or use ##778) and update your PRL file.
Boot back into recovery and do a NAND restore of your Sprint-based ROM.
It'll work just fine. Any of your ROMs won't touch your PRL file or PST settings. I promise.

Thanks Pkopalek got it fixed just a combination of not reading and paying attention.

Where would I go about diagnosing connection issues? MDA+TMO

Not to give away too much specific information, but I've got a new TMO MDA and the building I am in actually has TMO repeaters. Other TMO phones get perfect reception, and I can even put this new sim into my old unlocked HTC Typhoon and get perfect reception, yet my new TMO MDA won't get any signal.
I'm attempting to scour the registry to find some bit of info or a bit to flip or something of that sort to diagnose the issue. Our TMO rep apparently has RF engineers working on the issue, but if I can fix it sooner than they can I'd be happy.
So, basically, only these new MDAs (other new MDA owners are experiencing the same issue, as well as SDA owners) fail to authenticate to the repeaters in this building. I doubt the repeaters have a list of phones that allow authentication, since the Typhoon was never released by TMO and that can authenticate fine. So I'm thinking there is some bit on the MDAs that is sticking to one band frequency or another, or something to that effect.
Any idea where I could look for info, whether it be a web source or maybe a registry key I could tweak or something of the sort? I got the engineer mode to work (after another registry tweak to turn it on), and it isn't showing any information since the phone isn't connecting to any tower/repeater.
when you go to select networks to use, does the phone give you a list of possible cell networks?
Sorry if i sound obvious....but:
1. Have you compared the Roms on the phones? Maybe the new phone has a different rom which is causing the problem.
2. Have you tried the phone anywhere else outside your building...
3. The engineering mode will still work even without a SIM installed, so if your getting blank information then I think you have an old Rom
Hope this helps
Answers to questions in the thread:
1. If I go to select my networks manually, and it searches for networks, all it finds is the Cingular network, which I can not connect to. It won't find the TMO network at all. But I know it exists because other TMO phones work fine with full reception, and even my old Typhoon works with my new TMO sim in it.
2. The roms on all the MDAs shipped from TMO USA 1.8.10.2 and GSM rom 01.09.10.
3. Phone works entirely fine outside of the building. The building is shielded, but there are repeaters in the building for current TMO users. I know they work since other TMO phones other than the new MDA and SDAs work fine.
4. As for engineering mode... interestingly enough, now that I do have reception (I'm at home right now), I also get blanks. I thought that because I didn't get any reception, I wasn't getting anything from the engineering mode. But interestingly enough, I still don't even though I have reception.
Methinks I do need just the GSM rom. Someone mentioned it in another thread in the Wizard Upgrade forum. Where might I get just that ROM, maybe I'll give it a shot and see if it fixes before doing a full ROM upgrade (which I'd like to do for performance reasons, but I haven't gotten a definitive answer whether I can revert back to bone stone TMO roms with extended roms and everything yet).
I woould suggest getting hold of one of the phones that works, back up the registry, and restore it to the phone that doesn't work. That would tell you if its a registry setting, or a phone/rom problem

Well, there are no phones that work.
The phones that do work are your run of the mill non-smartphone phones, not a WM5 phone.
Actually, that's not true since my Typhoon is running Windows Mobile 5, but it is entirely different than the MDA.
Only all the stock MDAs shipped from TMO are failing to authenticate to these repeaters. Makes me think that updated the radio rom would help, or something on the repeaters is blocking just these two phones (the Wizard and the Tornado).
Try updating the wizard with one of these roms:
ftp://xda:[email protected]/Wizard/Roms/Tmobile/
Well, I updated the radio rom to 01.12.10...
And still wont connect to these repeaters. The phone seemed snappier to connect when I stepped outside of the building, though. So there is a plus. However, there has to be some reason the repeaters in this building are not allowing my phone to auth.

HERMES WORST NIGHTMARE - "the cell phone death trap"

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.

Is HSPDA in Haykuro's build really the same as 3G in other builds?

This is a question that has probably been asked before, but I did use the search function and I couldn't really find anything. Now that I've made that clear...
I've always thought that whenever Haykuro's builds say that you're connected on HSPDA, and display 'H' in notifications, it is the same thing as being connected over UTMS on any other build, and the notifications bar displaying '3G'. However, after reading a post in another thread, where someone had said that they were getting much faster download speeds in Haykuro's build than in JF's, and that they had actually run speed tests to confirm it, I'm no longer sure. Does anyone actually know if HSPDA in Haykuro's builds means the same thing as 'UTMS' in JF's builds, and if they are not, why we cannot get HSPDA in JF's builds, but we can only get HSPDA in Haykuro's builds?
Instead of opening a new troll thread why not use our dear friend google ???
GOOGLE
HSPDA=3G+
UTMS=3G
JF 3G = HSPDA/UTMS no distinction
HTC builds "H" = HSPDA
.... as mentioned before
This is not what I meant. I know that HSDPA is faster that UTMS, and I know what HSDPA is, but in that case, why should people not get HSDPA with Haykuro's builds only? Whenever I use Haykuro's build, I have HSDPA. Whenever I use a JF build, I have UTMS. Why?
OK:
The way I see it, TMO USA doesn't actively market a "HSDPA" network. They market it as 3G. This either is to be less-confusing (less 'buzzwords' to market) or less prone to cause uproar when people realize TMOs' network backhaul (the data path between cell towers and the TMO network for both voice and data) is not currently able to give users speeds as fast as HSDPA implies.
It is also true that currently their 3G network is HSDPA enabled, but due to backhaul limitations the full speed the network is capable of (7.2mbit in hardware, likely 1.8mbit in the cellsite radio software currently which with new licenses or firmware would be scalable to 7.2mbit) currently cannot be attained.
In the Denver metro, both HSDPA and HSUPA are enabled but the T1 (1.544 mbit) backhauls each cell-site has give me MAXIMUM 900kbit/s (0.9mbit) downloads and 300kbit/s (0.3mbit) uploads regardless of where or how I test. Consider that EDGE takes approximately 200kbit/s, and each voice call requires 13kbit/s plus some overhead. If a cell site is overloaded on voice, the data services will slow down. EDGE slows down because the same radio channels are used for both voice and data; more voice calls mean less datarate is possible. 3G will slow down due to sheer loading of the backhaul link.
As soon as TMO gets newer backhauls, either new fiber to cellsites, or perhaps a backhaul agreement with local cable providers, or even wireless (point-to-point microwave) backhauls to a centralized high-speed hub, I feel they will promote their HSDPA network much more like AT&T does now.
So to sum up: The only reason you see 3G with TMO sourced firmwares, is that they don't market HSDPA even if their network is technically capable of it. HTC however writes generic firmware and indeed many other operators worldwide will likely actively market HSDPA. I bet that if you were to take the firmwares apart, graphic by graphic / text string by text string, TMO builds will contain the same graphic twice (3g) and the same text twice (UMTS) whereas HTC builds will contain different text/graphics in each. There is nothing preventing the phone from utilizing the highest speed possible from the network on either build!
My slightly-more-than $0.02.
It was me who reported that.
I tested it on O2 Germany, no HSDPA with JF, but with Haykuros 6.0r1 and now with the leaked HTC Hero ROM too.
Seems like it does only work for me on HTC Builds..

I tested it on O2 Germany, no HSDPA with JF, but with Haykuros 6.0r1 and now with the leaked HTC Hero ROM too.
Seems like it does only work for me on HTC Builds..

Hmm, the libhtc_ril.so is different on the Sapphire builds. Try pushing this file from /system/lib to a JF-based build and see how it goes I'll do some testing tonight too.

I know I did get around 3-4mbps on JF's 1.5 while tethering using anetshare. So basically, it was running on HSDPA but the icon was '3G' and not the 'H' icon as in haykuros roms. So I guess it doesn't matter.

Hey, Good idea cyanogen. I have been wondering if we could get the T-Mobile/JF builds to display "H" when in HSDPA and "3G" when in UMTS. If you figure out anything that works, maybe this thread could be moved to the Development channel, or a new thread opened up there. If I can help, please let me know. Thank You! )
yeah, it's the same speed either way. I've tried speed tests on both various builds. I'd love to be able to enable the H icon so when I'd know when I'm in UMTS or HSPDA/HSUPA like when I used H build. It was pretty useful. I hope cyanogen can figure it out. I tried last week but couldn't figure out which file I was missing although I had all network icons loaded in my ROM.

Bingo. The actual speed is the same, it's just the status icon that is different.

In Texas here, I get different speeds in different areas. sometimes around 300k and sometimes around 900k. Which means that HSDPA has not been rolled out in all areas, or some towers only have one T1 line and it is pretty overloaded.

It could mean something or it could mean nothing at all. Also, does the difference in the build.prop values carry any significance?
Code:
ADP:
ro.ril.hsxpa=1
ro.ril.gprsclass=10
HTC:
ro.ril.htcmaskw1.bitmask = 4294967295
ro.ril.htcmaskw1 = 800881
In other words, do these values affect the ril and baseband or are the values already hardcoded in the ril and these properties are only for informational purpose?
At this point i'm more inclined to believe speed differences are chalked up to varying levels of bandwidth usage or limitation of the backend bandwidth (i.e. UMTS Node B -> carrier's inet backbone).
btw if one more person suggests that non-HTC builds can't use HSxPA because they don't have a "H" icon, i'll probably go bat**** insane.

Yes, but if you're in an area with a poor speed, an icon saying H instead of 3G, or vice versa, won't make a difference. The H is just there as a visual aid in the haykuro builds, it won't make your connection any faster. I do agree it's a useful aid as far as informing the user about the current connection status though.
It's like putting a turbo badge on a car, it won't make the car go any faster, it'll just let you and everyone else know it's a turbo. In the regular builds they, Google, decided to not use the turbo (H) badge even though there's a turbo under the hood.

I beleive the concern is that some users would like to know if they are connected utilizing HSDPA or UMTS. I for one would like to know if and when my area is upgraded to HSDPA. Just a feature request, not a rant.
Tested again with jfs 1.51... Checked the Phone Info, it says it is connected with UMTS.. went back to the Hero rom, said it is connected to HSDPA and displazed the H Too.

Did you try it with the new libhtc_ril.so? I included this in my latest build (CM3.2), but I am on T-Mobile so I need someone to test it out.

Hi,
I dunno if it'll help but few days ago I was playing with a program and was getting this results
Now with Cyanogen's rom 3.2 I get this so a small improvement
and my settings didn't changed
I hope It'll help

HSDPA, will donate for help!!

Hi guys, i know this is a common problem amongst some of us, there are several threads discussing the connection drops but please there must be someone out there who knows something about it.
Basically with HSDPA enabled, the connection will last a random period of time before disconnecting by itself and displaying: cannot connect for an unknown reason.
When HSDPA is turned off, only 3G is used, although this works fine, it is fairly slower.
I am on T-Mobile UK, I have phoned their technical support, we have established it is not the sim card but the phone itself and have tried a variety of steps to solve this, for example receiving band settings for WCDMA, this has not fixed the problem.
I have tried changing the username and password combinations and have tried every combination of every advanced network option. I have used the T-Mobile stock rom 1.43, official HTC ROM 1.66, duttys hg, energyROM, artemis 5.0 and artemis 5.5 (would recommend btw) using MTTY before every flash, and every single different radio combination.
Myself, and many people here would be very grateful for any help posted.
Thanks in advance
Why don't you try Settings > Connections > Advanced network > GPRS tab > change from PAP to CHAP.. and reset... or viceversa.. that helped for me..
Thanks for the post, i've tried all that i've tried all advanced settings, at most they last for a day or so but after a while the connection dropouts seem to worsen
Ok ive just gotten off the phone for the third time with the technical support
basically what they've said is that the hsdpa WILL disconnect because the mobile towers simply can't handle the traffic.
He said in his honest opinion I should disable it because it simply won't work well and there is no fix.
Taking the piss juuuuust a little bit
Mine on t-mobile uk will show H, but usually drop down to 3G. It won't give me an error when it drops down though.
It sounds like its not transferring from H to 3G.
To be honest, i was unaware t-mobile ran HSDPA till I got my HD2 (never showed on my BB).
mine switches between 3G and H too, this happens when the connection is being used (for example loading a web page) when the job is finished (page has finished loading) it turns back to 3G right?
are you saying that your connection never disconnects?
may i ask which radio and rom you are using?
thanks!
For my personal experience, I have for over a month, on versions 1.48, 1.66 by HTC, artemis versions, versions of other French chefs. had no problems,
Login Exchange push 24/24 without any cuts, I solicited the network with opera I passed automatically 3g H, and since February it to completely fall with the problems that everyone encounters (lost connection for several minutes , unable to connect to 3G without hard reset)
to remove the sim chip, I try with another chip of the same operator, another chip from another operator, the problem is still there.
For several days I have also continued a Touch HD, it faces no problems, no problems in connection 24/24.
In short, impossible to challenge any operator, any base station, any sim card.
It is then that the problem come from HD2:
-Software: We all try every combination of rom and radio rom possible.
It is the hardware, maybe the chip integrated into a concern for design, manufacturing concerns on some series, may be dysfunctional due to incompatibilitée between several chips of the phone, short, HTC should look into the problem.

correct, it never disconnects.
It will switch seemlessly between them, when using or not using.
same one it came with. O2 HD2.
ROM 1.43.206.4 (70315) WWE
RADIO 2.04.50.22_2
I've also been struggling with this problem ever since I got my HD2 three weeks ago. However it seems like only a few people experience this.
My case is exactly like cgrec92 described. I'm on a 3.5G network in Denmark (3 Mobile), the phone shows the 3G connection at all times. When things do work and I use Opera/weather/Twitter/email etc, the symbol changes to H and I know the data connection is functioning. I can be using this for a whole hour without any problems.
However, if I put the phone down for a while and then pick it up again to use one of its data services, very often it does not connect to 3.5G (or H) anymore. It will still show the 3G icon on the screen, but there's no data connection. Then I go to Connection Manager and I can see that data connection shows as Off - and after a few seconds it goes back to On by itself That does not mean the problem is solved, as the phone still fails to establish any data connection. What I need to do then is manually turn off data connection and re-enable it again, which makes the 3G symbol immediately change to H. Then everything starts working again - until the next time it stops working...
I contacted the HTC customer service and they said it might be a driver-related issue, recommended a hard reset. I did that and for a few hours I thought it solved the problem, but no, data connection still disconnects by itself.
I spoke to 3 Mobile's technical service and they told me to update my software, which I had already done previously (I'm running stock 1.66 ROM Danish). They also said they never received any such complains about the HD2.
Like cgrec92 I've also played with all kinds of network/band settings, but it did not make any difference.
***
One question: isn't the phone supposed to automatically connect via EDGE when it cannot connect via HSDPA? Because in my case it will only establish data connection via H, never EDGE.
Any advice is greatly appreciated!
My take on this FWIW
It's not the phone!
It's the radio ROM installed.
I live in an an area where T-mobile say I can't get HSDPA.
However, I know that I can. How? Because 3 network uses the same local cell and transmitter as T-mobile and their signal will rip your eyes out!!!!!!!!!
All information obtained from a good friend of mine who works for BT, who, service manage the cells for the networks.
Plus, in this location, the cell traffic is then handled by BTs digiatal backbone which takes it who knows where after that.
So I have a very isolated situation in which I know there is a decent HSDPA signal, but I have had trouble with drop outs on my two previous phones (Nokis 5800 and HTC Touch Diamond 2) and originally on my two T-mobile mobile broadband feeds using Huawei E220 cell network modems.
All fixed when I finally found the right Radio and flashed it on the phones and unlocked and flashed the latest modem firmware.
My broadband connections are always on and never drop out and my HSDPA signal on my HD2 is through the roof!
To further emphasise the point all the equipment is used (when home based) behind solar glass which is notorious for blocking mobile phone signals.
Land on the best one and you will get incresed battery life as well.
Bottom line is try the latest radios (2.08.50.08_02 in my case) and I think you may be surprised at the results.

I have the same problem with the connection dropping. What I did to make it work was to disable HDSPA and putting GPRS to CHAP instead of PAP, and so far I have no problems at all
Thanks for the reply and tips. I also did the same earlier today, except that I did not change PAP to CHAP :O. I was waiting until tomorrow before I posted any results, but I gotta say so far the connection has been stable just like yours.
I also called HTC's customer service in Denmark and the fellow I spoke to was very helpful but he said he has never heard about such problems. He sent me updated network settings via sms, but it did not fix the problem.
I mean, only some users around the world suffer from this problem, right? So what is it that's wrong with our devices? Is it a production fault? If I exchange my phone for a brand new one maybe I won't be unlucky again? When 3 DK finally told you the problem was unfixable, did they mention other users with the same issue? Did they ever offer to replace your phone?

Erm!
It's your radio!
But, I think I did say that in a previous post.
You had a helpful fellow who sent you updated settings?
And he thought that was going to fix your problem?
That was helpful!
It's your radio!
The technicalities are beyond a customer assistant at the end of a phone. They work from a script.
I'll send you the settings.
Have you done this?
Have you done that ?
Never heard of anyone else with your problem!
It's your radio!
T-mobile uses PAP protocol (at least they do here in the UK) and it's a handshake protocol so changing that won't really do anything to the signal definition.
You have it or you don't.
It's your radio!
There is no "production fault".
You are not "lucky" or "unlucky".
You are in an area where you will suffer from this because of the ???????
THE RADIO!
I think I have made my point.
If it turns out that you don't have a radio issue then please feel free to admonish me.
Until then----------
It's your radio!
well I don't mean to sound rude but do you SERIOUSLY think we haven't tried that? ive tried every possible radio available here and every different rom, so excuse us for trying new things.im glad your not having any troubles yourself because it is really annoying
perhaps you could post us your rom and radio?
I don't suppose you could post us your settings in advanced network?
did you use the connection setup?
thanks for your help
Yes, I was about to mention something similar. I haven't tried combining different ROMS & Radios myself, but I know people like cgrec92 who have with no good results.
And if it is the radio, then every 3 Denmark user like me would be experiencing the same problem, correct? I don't think that's the case. Actually when you read the forums you will find users from different countries with this problem, and they/we are not the only ones with a certain combination of ROM/Radio.
So yes, by disabling HDSPA I finally managed to have a stable data connection (but no 3.5G, obviously). At this point no one seems to know the cause of this issue, but I suppose it's naive to expect a future ROM to solve it, after all it's not a widespread problem. Is HTC even working on it? Are we sure it's not our devices that are faulty?
I honestly have no idea, but I cannot just accept this problem and live with it after all the money I put into this phone. That's why I brought up the possibility of having it exchanged for a brand new one in hopes that it will not have this problem.
Any ideas?

I referred to my radio in my previous post -20.08.50.08_02.
My OS ROM is Leo Lite 3.
Connection setup used and no further settings.
My explanation for this is the fringe nature of the received signal.
The radio its constantly 'hunting' for a signal and the radio software has difficulty in locking on.
BTW OS ROM and settings ready don't affect the efficiency of the radio signal.

I appreciate the help, but he doesn't seem to understand the issue here. It's not that we have low connection, or that we cannot connect to the 3.5G network. The problem is that the phone's data connection will automatically disconnect even when we are in an area with full 3.5G signal. The phone will connect for a while and then, moments later, in the same spot and with full signal, data connection is terminated. So I just can't see how the radio has anything to do with that, especially when there are hundreds of other users out there with the same ROM & Radio as us and in the same network. And yet they do not experience this problem.
Ive have similar issues but it depends where i am it appears that some towers its ok where others its not!

The radio differentiates between all the different levels and types of signal and it depends on how exact it interprets the signal. They are supposedly optimized before release and then re optimized with each newly released version. Network operators then have their own network parameters and again the radio has to accommodate this as well. One radio will never satisfy all these criteria and some of you will be in the wrong place at the wrong time on the wrong network with the least effective radio.
I can assure you that I most certainly do understand the problem and that is why, in my own case, I have resolved it.

Possible fix for data stalling issues some of us are having.

Right, a little back story.
I brought my SGS2 at the start of May in the UK on O2 so I have an early model which came with the firmware before KE1. I rooted in the first week and was flashing Villainrom 1.0 before too long with no data problems.
I think it was around KE2 with Lite'ning rom that I first saw my phone constantly switching between H & 3G and stalling when receiving or sending data. This behaviour has continued through all the firmwares I've tried with many different modems. I moved onto to Cognition when it was v1.01 and have been using it all the way unto 1.2 with the KG3 modem. Again still with data connecting problems.
Things I have tried -
Turning off fast dormacy
Editing the build.prop http://forum.xda-developers.com/showthread.php?t=1097612&highlight=build.prop pages 1-5
Switching off HSDPA/HSUPA via the *#301279# command
Disabling juice defender
Switching to WCDMA only
Changing modems
Full hard reset and reflasing of roms
Even with the above on multiple roms and rom versions my data connection was unreliable at best and killing spree warranting at its worst.
Possible fix-
What i found lurking on XDA on a slow day at work was the command below
*#2263#
This allows you to select which bands your phone uses. I selected option 2 then tested the 4 available bands. They all resulted in a complete loss of reception except WCDMA 2100. this is probably network specific you'll need to try it yourselves.
The results and current settings
Now when I try to use my data connection the phone no longer switches between H & 3G. It will start on 3G then find H and stay there, I see a slight delay if its been in deep sleep or JD has cut the connect but this is normal for the phone to start on 3G to save power.
Fast dormacy - off
build.prop -stock/unedited (I found this worked for me for a while but since 2.3.4 it didnt seem to help)
HSDPA/HSUPA via the *#301279# command - both on
Juice defender - on
WCDMA only selected as when picking a band it doesn't seem to like having a GSM band selected as well (happy to be corrected on that)
Modem KG3 -
Rom cog 1.2 - I'm patiently waiting 1.4 based on KG6 to test my findings.
Conclusion-
Okay it could be that selecting a band does F'all and that I'm seeing better results for a completely different reason. I'm not a developer so my fixing skills amount to playing with stuff I don't fully understand and seeing how more or less broke I've made it.
After thought -
Ive seen on the sensation forum they have discussed the wrong IMEI code being the cause of poor data speeds so I may look into that next.
Please share your experiences and anything else you've tried.

That should be no connection as IMEI belongs to phone and handshakes with network first .
KG6 modem some report as better .
jje
I will have to give this a try and see how it works, thanks for the share.
I am in the same boat, it is VERY frustrating to say the least. A typical scenario for me is: reading a web page on my S2 for a good few minutes (3g has gone to sleep mode by the time I have finished reading), I click on a link, 3g flashes, H comes up and flashes once.....wait.....wait.......wait......10 seconds later it decides to initiate a connection and take me where I want to go! It does the same thing with the XDA app. I have been onto O2 about this a couple of weeks ago, all they did was give me the settings over the phone (which were the exact same ones I already had) and they also sent me a replacement sim card, suffice to say, there is no change. Now I am convinced its a network problem of some sort, I have a three sim card which I have been trying out and the above problems do not exist anymore when using three, I click a link after 3g has gone to sleep and it goes from 3g to H and initialises the data transfer in one smooth motion. It looks like I'll be getting my PAC code and moving to Three!
would be interested to hear if switching to the 2100 band helps at all seeing as your on O2 as well
Mine is O2 via Giffgaff and no problems at all .
Tested KG6 modem Wi|Fi only and it is a stronger signal .
jje
Yeah, forgot to mention that, I have just enabled it. I can't test at the moment though coz there is no 3G coverage where I am. The only problem with enabling it is you will not be able to connect to GPRS or Edge if you need to. But it is worth testing regardless.
Just been out and about and tried that setting, didn't make much difference unfortunately
Maybe it was a combination of tweaks on my end. What rom & modem are you using?

Villain 2.3 with KG3 modem. The problem has been the same whatever ROM I have used, I even flashed back to O2 stock a couple of weeks ago to see if it was a ROM problem, but that was the same. I can't remember what it was like when I first got the handset though, mine was the first batch as well.

hi
i am just testing now this fix. i have an o2 phone and i did the same changes you did, disable fast dormancy, changed build.prop settings, will let you know after going a few times underground ;-)
gabrio
confirm, this is working, even when i go underground or when the signal goes away, it gets back to H/H+ and works, gabrio
Give it a little while, I think you'll be back saying it didn't work
Personally, I went ahead with my threat and moved over to 3uk, never looked back since with this problem, been perfect!
I've tried it all. Disabled fast dormancy, hspa, toyed with band selection, edited build.prop (btw, don't bother with it, the network settings you find on the web to type in don't work on the s2) you name it - but it would still cut out. Luckily, my phone is unlocked so I switched my provider and now it works like a charm with all the bells and whistles enabled. I can ride the tram all across warsaw and maybe have a handful of 2-3 second hiccups when I'm listening to online radio. Curiously enough, on my previous provider I've noted that there are some areas (like a busy mall - Arkadia) where it would not stall as well as a few other places, and most other areas that were notorious with data hanging. I'm convinced now that it is an issue on the telco side (*cough*Orange*cough*), and too bad because I was on a prepaid plan with them that for roughly $30 I had 7GB of transfer. I guess they figured they can promise the world on their trash network, because nobody would actually use it up. YMMV.
Had this issue with a UK GS2 purchased from Negri using it on AT&T.
Since upgrading to the latest UK firmware with 2.3.4 I have not had the issue going on about 2 weeks now!
Man was that issue annoying. Had to restart the phone sometimes to get data back.
Joe
Ok I did that too though how abt lag? Phone lags a bit opening large sms conversations and browsing home screens.. But peace. Yours too?
