Basically my student halls have terrible system due to it being a massive faraday cage. I know a lot of people with similar phones [desires] who get very good signal or at least some, while Im sitting in my room on either nothing or emergency only.
Is there anything anyone can think of why my phone wouldnt be getting as good a signal as it could?
Not sure if this kernal is undervolted but if that affects signal im happy to flash over it if you have an alternative.
Ta for the help.

Not sure if this helps or not, but if you enter *#*#4636#*#* in the dialer then select phone info and check the dropdown at the bottom of the list that is called "Set prefered network type"
see the link below for the options (second post), I have no idea if it will help but it's worth a shot:

On WCDMA preferred at the moment, as it should be I think.

ATT 8925 - Won't see 3G

Hello All,
Been reading this forum for quite a while, 1st time posting. This community has helped me improve my life immeasurably in the past couple years.
I got an HTC Tilt a couple days ago. Unfortunately it's not able to be returned or warrantied. When I first turned the device on it saw the 3G network (or at least displayed the icon; I never had the chance to connect). I navigated to my sd card and went to delete Fieldtest.exe, which I had placed there for ease of use from my previous 8525 (I do some network testing for my job). I forgot and tapped it rather than holding down the stylus and opened the program; the 3G icon disappeared and went to E and I haven't been able to get it back. I've tried clearing the memory and have completely reflashed the device using the HTC retail ROM. Also tried kaisertweaks to enable HSDPA and the bandselect tool.
This is really bizarre. I don't think that Fieldtest.exe could have damaged just the 3G portion of the chipset.. but I'm running out of ideas. I've searched through this forum (finding wonderful nuggets of information as usual - can't wait to try Digitaltigre's method for using the Kaiser, or maybe old 8525, as DiNovo Mini) and others to try to find others with a similar experience and I've done the obvious (reflashing the radio I thought for sure would do it). Besides this the device works great - EDGE connects and is usable, voice calling works, tethering works, etc.
Any ideas you folks can come up with would be greatly appreciated,
Thanks,
Shoehopper
ROM: 1.62.502.0
ROM date: 01/17/08
Radio version: 1.27.14.09
Protocol version: 22.45.88.07H
And I'm in a very strong 3G area (-65 to -70 dBm typically)
did u try changing your rom or doing a clear storage?
I tried both. The ROM I reflashed was the same version as the ROM that was already on it however.
try a different one
are you sure your area is 3G enabled? or at least have decent enough 3g coverage.
try this one addon it's called band select. it adds a tab to your phone settings where it lets you pick auto, regular gsm (G,E), or 3G. You can then force it to be on 3G only. The problem is, if this doesnt work it may mean what you thought earlier that either your 3G chip is messed up or you just not in a decent coverage area for 3G.
i cant find it on my pc, if you do a quick search you may unveil it. hope that helps
using 3g off/on in comm manager works for me or if i wanna get serious i use bandswitch or comm manager pro www.commmgrpro.com

Why is this? Even a secondhand Tilt will be less than 1 year old, and covered by AT&T's warranty.
I tried using BandSwitch, when I pick UMTS it constantly searches for signal (... under the antenna icon and x on the connection icon). Selecting Auto reverts to E.
I am certain of being in UMTS area (Redmond, WA HQ building of certain large wireless organization.. which is also why I cannot warranty or exchange he device).
Thanks,
shoehopper
errr nm i did some homework. Thought i had an answer.
eeeekkkkkkk
weird. I have some bugs depending where i am if the signals are real strong, i sometimes cant seem to leave my wifi on and stream info over 3g AND use my bluetooth. Are you running anything else at ALL. ? in the case i mentioned, i sometimes have to turn off my wifi to get my bluetooth to work.
Maybe some weird bug w/ something else your running?

Found on the side of the road?
fell out of the truck?
Stolen?
It was company provided, which means I'm not out anything personally, but it does have a $ value nonetheless. Being company provided but outside the retail channel, it is not able to be warrantied or returned. Sheesh.. people assume the worst.
I am not running any fancy connections. Haven't even turned on the Wifi or Bluetooth. No programs (besides the aforementioned kaisertweaks, and now BandSelect). It's not that it doesn't connect; it doesn't even SEE that there is UMTS coverage available, only EDGE.
Thanks,
shoehopper
I'd try a warranty exchange anyways, if I were you. (Once you've determined if there is a hardware problem...) Supposedly the warranty follows the device, no matter what channel it takes to get to the current end user. Anyways, that's what I've heard, and it wouldn't hurt to try. Just call customer service and ask for the warranty department.

[Q] 3G and network signal problem

Hi,
I recently updated to Froyo using the registry hack, i was on uk orange jf3 before.
Since being on it i have constantly been struggling with the 3g and the network signal, at first i thought the 3g was disconnecting when i turned the wifi on but then the network signal starting disappearing and it would show the circle symbol with the diagonal strike through it to show that it was not picking up any networks.
I read somewhere that cycling flight mode might solve the issue, but for some reason once i turn on/off flight mode it just hangs at that stage and will not change until after a restart.
I have also tried formatting both the internal and ext sd cards and i have done a factory reset twice.
Nothing has helped, it connects to 3g initially (which shows that it shouldn't be a setting problem?) and the network signal is also fine initially but then after a short amount of time or inactivity or switching on wifi the 3g won't connect and the network signal just dies.
If anyone has any ideas as to what is causing this or how to fix it i would really appreciate it.
Having a phone that can't make or receive calls when i need it to is really f'ing me off.
P.s. I have read and searched other topics for help on this but nothing so far has helped.

Yer i read your post, what i don't understand is that it was totally fine in 2.1 and now in 2.2 it's messed up, not sure if that is the same for you?
I think it is something to do with it being for Norwegian users not UK and that somehow affects it.
I have checked the apn and it all seems correct, do you also have the issue with flight mode not working properly?
Just found this on an internet search...
: Samsung Galaxy S v2.2/Froyo update
Posted: 5 days ago in response to: stefan
Some news on the update to Android 2.2 for the Samsung Galaxy S. Currently we are making some changes to get it working better when using Orange signal, and are therefore looking to release the update by the end of November – obviously this is a delay on our original release date but we hope it will be worth the wait!
Kind Regards

Not sure exactly what that means but it sure sounds like this might be the problem i am having.
I would be interested to know if other UK orange users have been having problems?
I would also like to know if it is possible for me to go back to to a previous version so i can actually use my phone.
I am orange uk, and have similar problem at home, but works well at office. Maybe it is due to the barrier of signal. if the signal level is lower than this barrier, only emergency call can be.
I do not know how to do but my friend advised me to update the moderm

JK3 modem, loss of all reception, drains battery, requires a reboot

So, right now I am using the Axura RC1 CE (I will update later), but I have had the problem described in the topic on various other ROMs using the JK3 modem.
It works fine for a few days (time is random, I have not been able to manually reproduce the issue), then randomly I lose all reception. Switching to flight mode fails, it gives no error, it just does nothing, in the notification bar it just says (searching). I have to reboot the phone to get the phone functioning again.
Anyone else experiencing this on ATTs network, or if there is a fix, I spent the last hour searching and going through the various threads to no avail (or I just suck at searching)..
Did you try the Axura thread?
Sent from my liberated Captivate via XDA App.
I'm having the same issue but I've tried Assonance as well and still get the random no service. Tried different i9000 modems as well--anyone know if its safe to use a captivate modem??? I'm guessing no but just want to know if anyone has tried it without borking the phone.

I'm having this same issue as well, that's why I've tried to stay away from the UGJK3 modem, however, it's seems every custom ROM is starting to use it
As far as using a captivate modem with an i9000 ROM, I've tried that also, while it didn't totally brick my phone, I did get random FCs. I've read that is a dangerous path to go down.
I feel the same way. I might try the CogKernel and see if that helps...
Please, please, PLEASE do not post these types of things in Development.
Sent from my Captivate.
+1 Lets keep this forum area clean .. its just for development stuff guys.
I have had the same issue with all I9000 modems, the only fix that has worked for me is to enter the service menu and force WCDMA 850 Band only. Also, questions should be posted in the question forum.
[this thread is pretty relevant to development - considering the rom chefs are using this modem in their releases and it has a potential major flaw. if the mods find it better to be in Q&A, then please move it - otherwise, i think the right eyes will see it here]
yes, yes and yes!
ive been posting about it in the perception thread, but no one (save for 1 user) chimed in with the same issue.
we both noticed that we both have an issue where we will bounce from 3G to H and back fairly often. this leads me to believe that it could be part of the problem.
i just odin'ed back to stock because my phone isnt receiving incoming calls now.
what i had planned to do was flash the latest perception but use a different modem... but it seems like the only sensible modem is the JK3 (although there is word on the street a new one just leaked?). so that idea is kind of out.
someone here said they were going to try cogkernel2, but i was on setirons and cogkernel2 and it happened with both. it seems to be a modem issue.
i wanted to lock the phone to use 3G only to see if that would help, but no one shared a way how... but reading this post it seems i can do it from the service menu - though i dont know exactly what to set/change to keep it only on 3G. (any help would be great).
so i believe im going to flash perception 8 and see if i can lock it into 3g mode and go from there. this is getting pretty tiring. im hoping if a new modem releases that will help, but i honestly am not sure i can wait since it is making the phone unusable.
below are my posts from the perception thread on the issue.

i searched but did not find...
i see others have had issues with APN force closing. i do as well, but assuming that isnt a problem, i dont mind.
my issue is that after a certain period of time left asleep, my phone will completely fall off the network. changing flight and data mode dont work, nor help. a restart works. this has started a day or two ago, but was not an issue for the first week (give or take). if it is relevant, my network constantly swaps between H and 3G where i live.
i have not found a setting to force 3g (and disable hsdpa) as i figured it was the network hopping that was doing it. am i just missing that setting? anyone else with this issue? (again, i saw people with the apn force close but not complete loss of network unrelated to initial flash)
also, i think that each build should get its own thread. it is VERY difficult to find accurate information on the current build once a thread has 4 builds and 250 pages in it. even with search, it would still be a good idea.
thanks and thanks.

of note: going into wifi settings is also borked. it will eventually time out and FC. i also think that the times my phone has completely lost network and not reconnected have happened more often when charging. but that could be coincidence.

in relation to my post below yours, does locking the 850 band only force the phone to use only 3G, or is HSDPA/HSUPA still enabled but you found the 850 band to be more stable.
this is what my next attempt will be to get a solid platform going.
I've tried different modems other than jk3 and it doesn't fix the problem. Stinks that you've used Cogkernel2 and it doesn't help. I also tried the different band selection in service mode and it also hasn't help me (apparently this worked for some people). If you want to give it a shot do the following:
1. Dial *#0011#
2. menu button then soft back key
3. then phone control -> network control -> band selection
4. good luck!

ugh. that is disheartening. i will try the band lock, thanks.
can you confirm or deny that when you notice your phone goes completely out of service that it has been hopping between 3G and H? it would be interesting to see if we all have that issue as part of it.
also, fingers crossed for that supposed new modem.
/sigh
Yeah this really sucks because these roms are great with this one very big exception. I haven't noticed the hoping before I need to reboot. I have noticed that if I switch into airplane mode once I drop service I can't turn it off.
I had the same issues with Axura and Percetion. I found that switching my network control to WCDMA 1900 only pretty much fixed it. The only problem I had after was that any time I lost service naturally, ie, bad area, or shielded rooms, whenever I came back into a good service area I could never get a signal again. So I would have to reboot.
In the end, I'm back on Cog, 2.3b7 and no issues for about 14 hours now.

Help!Wrong Radio Maybe?

Okay I need to know If the wrong radio can make the antenna I guess stop working? Because I have been running 2.22.27.8 For about a month maybe more and its been fine then out of no where my phone says No Service no matter what I try...What could the problem be?

1) just so you are up to date install 2.22.28.25 (this is the what the actual MT3G phones are running on the t-mobile network)
2) At least temporarily make sure you have both 2G and 3G enabled (ie that neither 2g only or 3g only are selected)
3) Settings->wireless & networks->Mobile Networks->Network Operators make sure your carrier is appears and is selected
If you are still having issues enter dialer and dial '*#*#4634#*#*' select phone information, under Set preferred network type choose WCDMA preferred. And see if that helps, if net doesn't appear after a min enter/exit airplane mode.
Other issues may be:
*) a change in your carriers network in your area
*) issue with the physical radio or antenna (this will not be fixed with firmware)
Is there damage to your phone in the upper right hand corner (it may have caused the antenna to become detached from the copper spring connecting it to the phone; or have you dropped it recently, The wire may have detached?

When I upgrade radios, will The latest SparksMod still work on there? and I haven't dropped my phone recently so I'm pretty sure it couldn't be that, and if its the physical radio would it be better for me to just upgrade phones instead of trying to get it fixed??

both 2.22.27.08 and 2.22.28.25 work with the new 2708+ kernels further 2.22.27.08 was only released on the original MT3G froyo update for t-mobile in the US. Since all world wide froyo releases for MT3G including a security update to that original US release used 2.22.28.25.
This to me indicates there may have been a problem with 2.22.27.08 and upgrading is advisable; as no particular problem has been reported with 2.22.28.25.
As for the physical issue: you have the right torx screwdrivers around and are otherwise willing to upgrade so don't care about voiding any service agreement its work quickly looking in side to make sure the antennas are correctly attached.. But do try all of the above first.

[Q] Mobile data connectivity issues, which radio?

Hi guys (and girls),
I'm going slightly mad trying to figure out a stable setup for my O2X. I have been switching between the latest CM7 nightlies, and MoDaCo FR19. In general, CM7 gives me quite frequent black screens, and FR19 seems quite stable. However, there is one issue that is present in both ROMs.
I am unable to get a stable mobile data connection when I switch from WiFi. Sometimes it works, and sometimes it doesn't. To get it to work again, it sometimes works to switch to 2G only (and possibly back again). I have tried several different radios recently: 218, 606, and 622, all with the appropriate RIL. The mobile data connection for 218 drops in and out at random without any clear pattern. For the other two radios switching on or off 2G only seems to achieve stable connection. However, it does not actually seem to affect whether I get a 3G or 2G signal. The display can say H or G, even when 2G only is checked. Bluetooth did not work correctly with 606.
To top everything off, the GPS does not seem to behave consistently for a all the different radio versions.
I guess that people have different experience with different radios, so which radio are the guys in Norway using? Do I really have to slog through every released radio and spend the day checking each one of them? Can I expect to find a radio/from combination that blacks to give me a stable GPS and mobile data connectivity, as well as good WiFi?
I know this has been discussed numerous times before, but people never seem to reach any conclusions. I'm just looking for advice on how to proceed to fix my problem.
I'm on cm7 .77 and i honestly havent had a blackscreen since i flashed it (yesterday morning) + battery is good now. For me this is the most stable nightly so ill stick with it for 2 weeks on my holiday )
Edit: bb .502 ril 218(i think) dont have any problems with network switching btw

You probably have to, yes. This sounds more like a problem with the specific coverage in your area and how the phone interacts with the cell-towers than an actual problem with the phone. You may be in an area with weak signals from several stations, you may be in an area suffering from sudden bursts of noise, there could be a lot of reasons for why this is happening.
First thing I'd try is to upgrade to the latest official firmware (10C - 0622 for Norway), just to have a baseline for comparison. In theory this firwmare (and baseband) has recently been validated by the norwegian carriers, and should have the best chance of success.
Then you should probably do a manual scan (in phone settings) for networks, and pick one manually.
Also try using the INFO menu (*#*#4636#*#*) and see if choosing a specific protocol helps.
If you're still unable to maintain a stable connection, I'd say that'd be grounds for returning the phone for a replacement.
Weak advice, I know, sometimes there just aren't any quick solutions.

Sort of. In this thread http://forum.xda-developers.com/showthread.php?t=1035041 you'll find complete ROMs of the previous versions. Install one of those with SmartFlash, then run the LG Mobile Update tool to get the latest.

Okay, I see, downloading now. So it is good enough to use one of the smartflash files, I don't have to use nvflash?

No, you don't have to use NVFlash. The advantage of using the smartflash method is that you get a completely "factory fresh" phone, with all the stock content present (movies, music, pre-installed apps) and you're sure to get a matching baseband and ROM.
Note that you have to flash both files, both the baseband and the ROM. The LG update tool won't update if you have a "new" baseband on an old ROM.
::Trym
So the firmwares from that post do not include the baseband? Anyway, I'm currently running baseband 405, so I guess this is sufficient to get the new update. And the new update will then overwrite everything to the latest official version, both ROM and baseband, correct?

Yes, it does. Each firmware pack comes with TWO files, the baseband and the ROM. To make sure you avoid any trouble, just flash them both, though, as you say, you can probably stay on the one you have, as yes, the LG Mobile Update tool will overwrite both the baseband and the ROM with the new versions.

Flashing of old firmware, with subsequent upgrade to latest release for Norway is complete.
I got version V10c, with baseband 1035.21_20110622, kernel 2.6.32.9. My mobile data seems to be enabled as soon as I get mobile coverage (which admittedly is poor right where I live). Even though it pains me, I guess I should leave it as stock for a day or so to see how it behaves.
I guess rooting it shouldn't affect performance in any way?
My initial experience is that it is much more snappy than the stock firmware that the phone came with, but time will show

Not to my knowledge, but I'd still advise you to wait a few days while sorting out the connection issue. Not that I think rooting it would affect that one way or another, but if you can't get it work as it is, you can return the phone in the state it is now, factory fresh.

It certainly is. It also *stays* snappy over time, which can't be said for the 10a/b versions.

The first test drive with the new firmware has been completed. On the way out it switched to mobile data flawlessly, but a longer drive it started falling out and reappearing for only short periods. When we stopped at the destination seemed to stabilise with a 3G connection again.
For the return trip I selected use only 2G network. The network connection remained stable for the entire journey.
I will have to test more, but the conclusion seems to be that it has trouble switching between the 2G and 3G networks when moving. I will try the same trip with a Telenor SIM card, and with different combinations of enabling 2G and 3G modes.
By the way, what is the difference between forcing 2G in the regular settings menu and in the special information menu?

I will have to test more, but the conclusion seems to be that it has trouble switching between the 2G and 3G networks when moving. I will try the same trip with a Telenor SIM card, and with different combinations of enabling 2G and 3G modes.

The 2G only setting in the phone menu equals the "GSM only" setting in the INFO-menu. I'm far from an expert in these matters, this thread has an overview: http://forum.xda-developers.com/showthread.php?t=675136& of what the different modes do.

More testing seems to indicate that as long as i leave "use 2G only" check, my mobile data connection seems to be pretty stable. It even switches between 2G and 3G, although apparently a bit more conservatively.
I guess I get to keep my phone anyway
Now for some rooting...
Just an update on the results from my testing. The second time I went out my mobile connection never appeared. This was with only 2G checked in the settings menu. In the Info menu, this corresponded to GSM only.
I then changed it to GSM auto (PRL), and then I got my intermittent mobile data again. I then change it to WCDMA preferred, and my data connection seems to be stable for now. This apparently requires much more testing...
F another chapter in the connectivity saga. Having WCDMA preferred selected in the Info menu, things mostly work, although the data connection drops sometimes.
Another problem I'm noticing with the stock ROM is that it usually is unable to reconnect to my home WiFi network when it comes within range. I have the money was selected to reconnect. Sometimes I even find it disabled in the list.
