Vario II network coverage question

Recently my Vario II intermittenly loses network signals, it says No Network and I have to toggle phone off/on to make it search for signal again. This only happens when I'm at home (Charlton SE7 area).
Rom 1.21.110.3 (19/06/06)
Radio 1.05.05.00
Does anyone have the same problem?

Flash HardSPL first, then upgrade your radio.
Ive linked to my guides incase your unfamiliar with the process.
The newer radio should possibly increase your GSM efficiency. Are you in a decent area for reception?

Hi, many thanks for your detailed guides. I've upgraded Radio to 1.38.00.10 but the problem still persists. I'm in a very good coverage area, always get full bars 3G when it works. Soft-reset my phone and now it's searching in vain for network signal, I'm confused

What operator are you with ? Maybe the cell where you live is getting overloaded. We had a problem similiar to this last month when our local base station had a problem. Our work-around was to disable 3G but not using a Hermes . Apparently the handset tries to register using the 'best' data-bearer its configured for. So disabling 3G made it register with GPRS which worked fine. They then fixed the base station and we were able to re-enable 3G. I would
guess Charlton would have a lot of subscribers per cell. You would expect the coverage to be better in a built-up areas but who knows. Maybe an enquiry/ complaint to the operator would at least tell you if they know of a problem and if its temporary or longer term

Cheers for that. I'm with T-Mobile. What's bugging me is that this signal disappearance only happens sometimes. It's not that I don't have 3G (or signal for that matter) at all, I still get full 3G signals fine most of the time. But you probably were right, looks like it's a fault from the operator's cell in the area, I will give them a call next week to see if there's an explanation.

I've noticed this problem when I'm in the south London area (very general I know). People have got around the issue temporarily by forcing the phone to GPRS only

More problems! After upgrading to 1.38 and trying all sort of "good" radios like 1.17, 1.27, 1.34 I can't make/receive calls unless GSM is forced. There must be something wrong within my immediate area because with the same radios everything works flawless just 10 mins down the road. I just called TMob and there's no technical fault or anything from their side. I will just have to put up without 3G until the problem fixes itself

There are lots of people complaining about 3g on T mobile in UK. They seem to have serious issues with Hermes devices and the dropdown to GSM.
I had a problem six months ago with my hermes on orange at home in SW London. For a few weeks it was mucking about - I rang O who advised me that they were experiencing some local issues but would fix them within days. I switched to GSM for a few days. When I switched back its worked fine for last five months.

3G gone mad!
the same thing was happening to me. Full 3G reception in Leicester, tried to connect to get my e-mails and then the signal totally goes. The same thing happens when I make calls as well. Switched to GSM and everything worked. Now in York and everything is working on 3G.
Network is T-Mobile.

This sounds similar to the issues I am having.
Do you get the phone hanging as it attempts to start a call and then after a while a message stating that it was unable to connect?....sometimes resulting in a soft reset to bring the device back online? In my case toggling bluetooth will reset the connection.
I am with T-Mobile in Glasgow but get the same issues during the day in Edinburgh

No 3G

No mine doesn't say anything, it sounds "ding ding" after a few secs like when you press the hang up button. I can use the Internet but anything to do with calls is just impossible. I've switch to GSM now and everything's back to normal. A bit annoying can't use 3G at home.

Weird roaming connectivity and other stuff with MDA

Cross posted by me from the Herald area since I also experience the problem with my TMO MDA running an older Molski ROM. Since the Wing and Wizard are so hardware similar, I thought I would bring the issue up here too.
Looking for ideas!
I'll grant you that at least part of this is likely TMO USA's network, but here goes.
Frequently when I roam with the MDA, the connectivity of the device simply "weirds out". No SMS/MMS, Voice, data, etc. even after I return to a TMO service area. Soft reset fixes the issue always, sometimes going to flight mode and back will clear it.
Related issue, one that I also experience on the Wing/Herald and have only heard vague rumors about from others, is that frequently when roaming and continuing afterward, the pitch and speed of all system sounds on the MDA will go up by about a third (think cartoon mice), this affects all system sounds including voice command and media player, but NOT the voice in calls. Soft reset clears the issue.
Lastly, while travelling, I nearly always lose the ability to send SMS/MMS messages, even though I am in a TMO coverage area with good data and voice after a clean soft reset.
It FEELS like a generic issue with the radio ROM or perhaps the radio hardware, but I don't have a lot of skill at that level.
Thought anyone? Anyone else having similar experiences?

HD2 Web Connectivity Issues and Analysis

Seriously people....
I've seen lots of threads recently. People are complaining that the HD2's data connection cuts out, leaving them unable to access the Internet from their phones for who knows how long. I know, it IS kinda annoying...But the thing is..
I can tell you this IS NOT a hardware problem. It's something to do with either the OS....or something in the phone's registry settings which no one has picked up yet...I hear that phones like the TP2 do not have this error, and I agree. My old unbranded Touch Pro 2 was brilliant, I could use it for IM and texts anywhere...LOL I used to sit on the Bus while people stared at my phone, while I was on Messenger talking to my phone. Anyways, here's what I wanna tell you guys. Hope I help out everyone in some way or another.
What I have:
HD2
3 Mobile Sim-So yeah, My Operator is 3 UK
Living in London, UK
Using ENERGY's 17th March Version ROM
HUSPA, HDSPA Enabled
What I've noticed:
The phone cuts out the signal when the transition between 3G and H occurs in the icons. As a result, the Internet cuts out temporarily, and programs such as Messenger lose connectivity for a while. For example, when the icon is on H, and no one's talking on Messenger, the Icon changes back to 3G....during this moment it cuts out sometimes..until it reverts back to the H icon (Got that? I know, it's a little long and complicated when I word it like that, but read it out and it'll make sense xD)
Now, whenever I have the phone connected to my PC/Laptop (Either as a Wi Fi Router or through the cable and then using Internet Sharing, either way, the phone does NOT change back to 3G, it stays constantly on H (Mind you, I usually download during this period). Anyways, the point being that the connection is VERY stable and constant, when in this state, connected to my PC/Laptop and the device is accessing the Internet through my phone's Data Connection. So what do you all think? And what have YOU found out? Leave your responses and ideas below

Some things I have found out are, if you Enable ONLY HUSPA in the Settings/Connectivity options, the connections seem to be more stable. Furthermore, if you really want to, Disable Advanced Connections, stay only on 3G, and enjoy a LOT of stability (At the cost of slower speed surfing and downloading )

My HD2 does not connect at all anymore. I called in to support because I completely lost data connectivity (web browser, email, slacker, whatever - no connection). They verified no troubles on their end. I moved the sim to my old touch pro (running Energy ROM w/ winmo 6.5 and Sense 2.1) and that phone connects fine. So it's not the SIM, and it's not the network.
I've also done a hard reset to get back to stock and still have the problem, which tells me that it's not a registry / software setting.
They only thing that leaves is faulty hardware - or firmware that a ROM hard reset wouldn't affect. Either way I need to replace the device altogether.
Unfortunately, tmo is out of stock and so I can only wait for a more to become available before it can be replaced.

Which phone company are you with? I experienced the same problem with 3UK in North London for a couple of months up until the beginning of last week but it was a problem at 3's end, not mine. Other people have been experiencing similar issues with non-3 phones in London (http://www.3g.co.uk/3GForum/showthread.php?t=102192).

yes, I had problems in London too before Good Friday. Especially on Tues+Wed.
Others around me inthe library also had similar issues with their iphones. I kept on switching the baseband and modes, and reapplying my 3G settings to keep it alive and solve the outages.
Most people with issues were on vodafone or O2 (like me).
It would work, then cut, then work.
I thought at first it was because I had a custom ROM, but iphone users had the same - and lots of timeouts on requests.
I DO believe however that running ROMS like energy's and Dutty's HG 1.7 with 2.10 (which I'm currently running) bases as 2_08 radios is not great for the uk and exacerbates the connection issue. 2_07 is better...and in any event we SHOULD be using 1.72 based roms with 2_09 radio.
I have also noticed that on COM5 23544 builds the opera mobile 9.7 and 10 google boxes do not work. They come up as failed connection, but then i click on teh link and it works...weird huh???
So I think last week was because of network faults in London. But in general, these 2.10 based ROMS and their radios are not ideal for stability.
I had perfect call and HSDPA stability with 1.48stock+2_09 radio.
Having turned to a 23544 rom (Dutty's HG) with 2_08 radio I've had much less call and internet stability (and quality) over the stock with 2_09.

How Many People Are Having MAJOR PROBLEMS with DATA on T-Mobile HD2(Stock Rom)

Because this is F'ing ridiculous. I'm soon going to be on my 3rd HD2(T-Mobile is shipping me a new one tomorrow) the previous 2 just kept dropping my data connection. After about 3 hours of LESS of use my data would go out and only way to fix this is by doing a soft reset which is absolutely ridicules considering the damn thing just came out not less then 3 weeks ago. Am I just having bad luck or is there really an issue here that either T-Mobile or HTC need to address ASAP?!
UPDATE
ok now im starting to think it was T-Mobiles network not being able to handle all the new data over there lines or what not. Its been a full 2 days and I'm getting great data coverage. I'm getting my replacement HD2 tomorrow via UPS since I called T-Mobile and told them about the problem they said they would send me a new one. What should I do now. Its such a pain to have to set up my phone the way I like it but then again I dont want to risk having another data problem.

Dude, you are having some bad luck!
My phone is perfect. Well, it could use a keyboard, but otherwise...

same problem
I am have same problem..t-mobile 3g sucks i guess

It appears to be a common problems with HD2 users on the other side.
http://forum.xda-developers.com/showthread.php?t=614119&highlight=connection

I was on the phone with T-mobile a few hours ago for an hour because my data connection would randomly drop. When I try to click it to turn it on, it would make me start a new data connection, wtf?
If I turn my phoen off and back on, it wouldn't even connect, with anything. The guy at T-mobile made me do a hard reset. My connection is fine now, but this was a hassle. I also notice Im not getting any better 3G service (as he said he update my network with better coverage).

I have the same problem with my phone. I have to constantly turn the data off and back on to get connection.

Both of my phones are doing it. They were both replaced recently too. Wish I could vote twice.

same here even if i have a full 3g bar data wont stay stable

No issues here.

been reading and stuff and more than half of the people with an HD2 have this BUT THERE IS A FIX search for it just like I DID
if you can't find it ill just post the cab latter when I got nothing bette to do.... haha lol

That's great for you if you have a problem lol...I didn't when I was on stock. Glad to be on Elegancia now...pretty good s***.

No issues here. Bayarea.

The other day, I was in the Dade County Fair in Miami and my cell phone completely lost all connection (not just data, but cell signal as well). It would randomly come up again for a few seconds before dropping. I soft/hard reset, took the battery out for a few minutes... nothing seemed to work, so I called TMO USA the day after to see if maybe I was in the middle of an outage, but nothing and the guy from tech support couldn't help either... I had better service with MetroPCS....
The data connection dropping happens the moment I set foot in my home. It switches out of 3G and the phone starts displaying Edge, which is a lie because there is no network connection at that time (try to update weather and it simply spits out a connection error). I'm gonna try to flash something else and see if that works (I am on stock right now). If I cannot get this solved by the end of this week. I am switching to Sprint and getting myself a TP2 (since I need SIM card capability in my phone).
I did notice one strange thing though. I used CleanRAM (level 3 option) at one point at home when I was with the faulty Edge, and it switched back to full 3G. So, at this point, I am starting to believe that TMO put something in the stock rom that either hinders, or makes the connection lousy...
I guess I put away my ORD for as long as I could with this phone

To put it lightly, T-Mobile plan sucks in my area, I had to switch to AT&T ever since then I havent lost any data connections.

Although I just moved to EnergyROM the other day since I just like that ROM since I used to use it on my Touch Pro. I never had data issues with the Stock ROM. Only time I had a data issue is when there was an outtage in my area and then even the phone didn't work.

I could not get my data connection to stay on more than a few minutes at a time until I loaded up HD2Tweaks. Since then, it's been running perfectly.

It's odd...however, if your phone's only problem is just switching between Edge and 3G try setting the phone to only run on 3G...under Settings->Wireless Controls->Phone->Baseband->WCDMA...
If your phone is cutting out...that sucks lol...not a whole lot I can think of except for the fact that the laws of physics apply in this case...the higher a frequency is, the farther it travels with less energy but the less it penetrates the environment around it. This is in part caused by higher frequency waves becoming extremely tiny, with over 1900mhz having waves that are smaller than a drop of water.
AT&T 3G uses 850mhz and 1900mhz for their 3G. Its lower frequencies don't travel as far, but they have more towers to make up for coverage area and the signal will penetrate.
T-Mobile 3G is 1700mhz/2100mhz meaning that the slightly higher range, while seemingly insignificant, when coupled with less towers, will cause the far end of the signal range to have too great a degradation of power, and not enough penetration to be viable.
Along with this is the fact that many government agencies still operate on the frequencies that T-Mobile purchased, due to not having a backup for their systems. Enough power generated within a frequency range will raise the noise floor enough that your phone's signal will get cut off. Sounds crazy, but it does happen quite often. You ever hear static on your radio? Analog is great in that you can lose data and still function. So government radio's are perfectly okay with a little bit of background noise.
However, signals that broadcast an analog translation of a 1's and 0's, function like a digital connection. When packets of information are lost in significant quantities, or in this case they are known are "frames", your phone cuts out.
Signal interference is becoming more and more of a problem in the cellular world. Satellite communications have had to deal with this problem for years. Only now are enough cell phones being packed into a single area for the noise floor to rise in significant quantities.
Just my $.02

for those who fix the problem can you post how you guys did it. i tried changing data to just 3g didn't work changing to voicestream it didnt work

I'm using HD2 since 25 march. Stock room. So far no problems.

Network and GPS Functionality Vanished

Hi all,
I flashed my phone, and thought I’d go with Darky's Raw Steel Edition (4.1), which is awesome btw. I installed it correctly, installing I9000XWJM8 first (the MODEM and PDA, not CSC as none seemed to come in the package).
Everything was working smoothly until I realise 3G/Data Network is no longer working (it did previously). Not only that but it seems it won’t connect to my service provider (Three) at all (emergency calls only), and I’ve also now noticed GPS doesn’t seem to work at all, I can’t even get into GPS test mode. Wireless does however work though it being off, or on, has no impact.
I’ve tried:
Flashing different firmware - Stock JM8 and Doc Froyo’s latest JPO.
Hard Reset
Deleting and re-entering APN settings, though they were correct and already on the phone anyway.
Testing my SIM on another phone – signal is strong, inc. 3G on that.​
I’m really at a loss here. Any ideas anyone?
Thanks
UPDATE: So, I won't bump this myself, but incase anyone finds this thread in the future: the gprs, gps, 3g, etc all work - just not in my house, on the SGS, anymore. I have no idea why - my other phone, it's fine.. and it used to be fine with this phone too. I'll update again if I figure it out.

the other phone works fine with the same sim you are using in the SGS?

Yep, the same SIM works in my old Nokia 6600 fold, people in my house also with Three are getting solid reception right now. 4-5 bars with 3g established.
It worked beautifully all the way home from work on the bus, just not in/around my house.
It's as if the local cell towers near my house have blocked my SGS specifically (can't receive calls or texts either). I did turn the wireless on and off in short succession (which would cause the gprs/3g to try to re-establish each time).. maybe I flooded them and they blocked my IMEI? Or is that just a ridiculous idea?
The real odd thing is GPS not working either (again, just around my house/street); surely it doesn't need a cell site for that?
It does seem as if I can't download apps from The Market anymore either, and have tried various cache clearing solutions to fix it (problem occurred roughly when I noticed my reception was nill).

You might have a problem with the band selection thing of your phone.. have you tried downloading/speed test when you /do/ get a connection? If it seems capped at 40kbps, you might have the same problem I experienced before, of being stuck on 2g. (Despite settings saying otherwise).
I fixed it by doing the solution to having a missing 850 band, the thread of which is found somewhere in this forum.

Thanks. That sort of worked earlier.
It made a slow data connection, and some texts came through.
I then went out to a location a few miles away, had a look and it was still on a slow connection type for a few mins, then all of a sudden it went to HSPDA (with the occasional 3G flicker) and was blistering fast.
Now that I'm back home, I've lost all reception again and can't make/take calls
[EDIT] Clicking around my phone in the hopes of finding something: checked product code in my nv_data.bin file with SGS Toolbox, and it's showing I9000HKDKOR; whilst the backup is showing I9000HKDH3G - could I be on to something? I backed up my efs folder after rooting before doing anything else - so, going to try restoring that.

I have a hunch based on a 2 year old post (http://forum.xda-developers.com/showthread.php?t=445913).
From what I understand, Three UK piggy back on Orange's network when Three's 3G cell towers are out of reach. Orange don't provide Three users with the full service though, just 2G and I'm guessing they prioritise Orange customer traffic.
I think when I flashed my phone, I removed code commanding the phone to prefer Three cell towers. Without that code, the phone simply goes to the strongest/first signal it detects. I'm guessing in the area near where I live, it's Orange (or maybe any old network which is why I'm often getting Emergency Calls only).
This is all guesswork. I'm hopeful, seeing as if I quickly switch the SIM to my two+ year old phone, then I quickly get 5 bars and 3G.. unless the SGS's signal issues really are *that* bad.

http://forum.xda-developers.com/showthread.php?t=831022
Try see if you have the symptom of a missing band?

Hi Nwsk, I tried that before and assumed it didn't work, but actually the change isn't sticking. Which seems to be the case for a couple of others! Thanks for pointing me back to it!
[Edit]
Ohhhh dear. Now I have another theory (I really hope I'm wrong).
I've just read on a thread that some phones don't have the 850 Band, it's down to a lack of hardware support. I'd wager every Three UK branded phone sold will have the correct hardware as stock. I sent my phone back to Samsung for repair, they said they replaced the motherboard.. inference: they replaced it with one without the WCDMA 850 support.

Hmm, I'm definitely no authority on this, since I'm just guessing.. but I figure if that if was a true hardware defect, you wouldn't even be able to get it temporarily?
Are you using any 'battery-saving' type apps? Something might be messing up and keep reverting the settings. I had this occur to me a second time when I was trying out the superpower app here, I think it conflicted with another app I was using, and it borked out my network connectivity. Somehow fixed that after a few reboots, and lots of messing around in the phone debug menu with the 3g/2g thing, it suddenly worked again.

I've not seen it manage to get onto 850MHz WCDMA in my house for a while, not since the mobo got replaced (I should qualify that with a statement on my bad memory ). It will occasionally latch onto something if I walk around the house, giving me a slow data connection with the G symbol showing - it will drop pretty quickly.
Messing around while I write this, I've just realised if I set my phone to GSM(2G) with roaming [Three UK phones need this on so they can connect to Orange towers], then it does establish a data connection at 1800mhz. If I force WCDMA only, I get NOTHING. Setting both/auto leads to it being dodgy/instable, as I've discribed above.
My Nokia 6600 supports 850mhz UMTS, which would explain why it's working well inside my house.
I don't think it's an app. I've flashed a few different firmwares in an effort to get this fixed, it's currently on official Froyo JPO (not even rooted!) with Multi-CSC and a few completely harmless apps. I'd try the stock Three firmware if it was available somewhere.
I'm hoping it's software like you suggest! I will tinker away for now!
Thanks for all the help, at least now I'm fairly sure I'm on the right track!
