Treo 750v Radio ROM Deteriorates with Time - Palm Treo 750 ROM Development

I have flashed my unlocked Vodafone 750v used on AT&T in US several times to
1.15-VFE
firmware 1.52.3.00
How do I flash to a more stable radio ROM?
I have such bad reception after about 3 months of an otherwise initially very stable ROM, that the phone part is barely usable now. My present ROM otherwise stable with no need for resets, but I have noticed the phoen reception gets worse with time, has anyone else noticed?
I am almost ready to give up on the Treo 750 if I can find a comparable device with threaded SMS & HSDPA

Changing your radio will NOT fix broken SIM cards, WiFi problems, Bluetooth issues or external GPS problems, Nor will it magic up a signal from nowhere if you live in a poor coverage area It may however resolve some network connectivity issues or help improve data speeds.
Having the latest release does NOT necessarily mean it is the best ROM for your network or country. In extreme cases a later radio may introduce more issues than it fixes so treat all upgrades with caution.
It is (in extreme cases) possible for the radio firmware to kill actual radio hardware if something is badly wrong or a radio firmware is buggy. This is rarely seen but is potentially a real risk.
Any update that drives the hardware "harder" in order to increase the gain of both the transmit element and recieve pre-amp element in any radio module is usually at the expense of the lifespan of the radio device. To put it simply, high output devices tend to have shorter lives than low output devices.
Problems with the device emitting more heat than usual, shorter battery life, long drop out periods where the device looks for a network or other "odd" intermittent radio issues can be a warning that something may not be right.
Recently the battery consumption of popular radio stack versions have been tested and compared. See this thread for more details.
Finally - always experiment cautiously, be aware of the risks and minimise them and read other peoples experiences on the forums before just taking the latest image and flashing it (i.e cross reference posts, see where posters are reporting from and take some proper time to do some research BEFORE considering flashing a new image - this way you are less likely to encounter problems and should have a good idea of how an upgrade will perform before exposing your device to any risk).

Thanks fatality, that looks like a Hermes radio ROM, does it work on the Treo 750?

10 charcaters

Yeah, Use the KaiserCustomRUU utility - http://forum.xda-developers.com/showthread.php?t=334890
Place one of the Hermes roms (.nbh) files in the same folder and execute and follow instructions
Hermes and Treo use the same chipset and the Hermes ones I have tried (3 or 4 of the latest) have worked fine
You will need to hardSPL your device though - http://forum.xda-developers.com/showthread.php?t=334100
Some roms will work differently and you should be able to find one suitable for your carrier/data/battery needs...
ps. i of course hold nothing resonsible but i have got into no trouble myself...

Upgrading from 2003SE: Which rom to use?

I am interested in upgrading from 2003SE. I have a PDA2K with the versions specified in my signature. Here's what I do with my device in order of importance:
1. Phone
2. Bluetooth headset for phone usage (Motorola HS850)
3. PDA sync with Windows/Outlook for calendar, email, etc
4. GPRS for IMAP email reading, downloading of pocket weather info, etc.
5. TomTom with a Bluetooth GPS
6. Solitaire / games
My current device is fairly stable and does not require a reboot more than about once a week. The phone functionality works well and I can hear the other person, they can hear me, etc. Bluetooth isn't great, but I don't think anyone with this device can say it is great.
I am an experienced user/upgrader and can perform all upgrade steps, I just don't want to have to muck with it on a regular basis once it's upgraded. I'd like to stick to every-six-months type of upgrade cycles.
That being said, what is currently the best upgrade ROM in terms of speed, functionality, and most importantly stability? I have read many posts and can tell which is the NEWEST, but not necessarily which is the most stable.
Thanks in advance.
-RJB
I think that the best rom for you is T-Mobile 1.42
For the things you want to do the fastest speeds you can gain with 2003 SE, WM5 does not meet your requrements for OS
You can always choose difrend rom from here
T-Mobile 1.42
the T-Mobile 1.42 ROM does it have to be a stateside pda? or can it work on my unlocked QTEK9090 that i bought here in italy. And will it work when i got back to the states in a few years?
It will work everywhere, only problem with uprading that you may have is that you may have to flash the rom using MaUpgradeUt_NOID, which disables the check for an operator
Interesting
Interesting, so you think an upgrade to the T-Mobile W2K3 ROM is better than moving to a WM5-based system, such as TuMa 1.4? I was hoping the WM5 stuff was stable enough to use on a daily basis.
I'll check out the T-Mobile and a radio upgrade since I have fallen behind in that area. I'd like to hear more thoughts about WM5 and the various versions out there.
Thanks for the responses.
The T-Mobile 1.42 ROM is from t-mobile.nl, so it loads in dutch on first start up but is written in WWE so you just go into the regional settings and choose whatever language you want.
I have found it to be very stable, I do a soft reset maybe once a week and that is usually just to regain the sd slot, it tends to say empty even though there is a 1gb card in it.
Only problems I seem to have with this are the BT doesn't like to turn on, you get the insufficient memory error, so I leave BT on all the time, and the wifi usually requires a soft reset to enable, which for me is ok because I do not use it that often.
I have not had to do a hard reset since upgrading to this ROM, it has been so reliable for me that I am very hesitant to upgrade to WM5. I just don't think I would gain anything from upgrading. though I am sure i will eventually.

NEW HTC WIZARD radio 2.40.11

enjoy....

ftp://[email protected]/Wizard/Roms/faria-roms/radio2.40.11.zip
The link doesnt work for me faria. I just went to the ftp site and manually downloaded the rom.
I cant access the FTP site. It keeps asking me my usnername or something so I figure the xda login name right, but it doesnt work. Can someone upload it somewhere thanks
Thanks
Download works fine for me. Just put xda in for the password. I'll check it out and see if its a reasonable alternative for the 2.19.11 rom and my Cingular service!

Thanks, I finally was able to download it. One question before I upgrade. Maybe Faria can give his input. I am a T-mobile user currently on the 2.19.11 radio rom. This seems to be the best one overall for me since it allows both data and voice calls at the same time, there are no missed calls. But reception/signal is somewhat not good. Does this new radio give better reception for T-Mobile as well as allowing both data and voice?
Thanks
Great radio rom but isn't 2.69.11 newer then 2.40.11?
Well, right, it is newer most likely. The thing is, newer isn't necessarily better for each person's circumstance. Radios are tuned for particular providers in particular places and are usually matched with particular roms. However, in my case for example, with Cingular US service, and WM6 roms, my experience and that of many others is that the 2.19.11 T-mobile UK rom is the best. The others were inconsistent in alerting me to incoming calls and pending voicemails. However the data and sound was better with the newer radios. For me not missing calls was most important, so I stick with the older rom. But, this is a new one for me, and hope springs eternal, so I'll probably give it a try and see if I can have the best of both worlds like those T-Mobile guys.
Regards,
working well on farias "the real thing"?

From what I understand, 2.69.11 is the latest released German Radio rom, but 2.40.11 is a US released rom. So this may work better for US customers. I hope we can use 2.40.11 with WM6!
testing
in the midwest US of A baby.. smoke you!
Just installed it! I will post back my results.
Since I finally experienced the awful delay in SMS receiving on the 2.69 radio ROM (after several weeks of success, I missed 4 important text messages in an hour's timeframe), I'm game for this. Downloading now...
So far my signal seems to be much better than 2.19 radio. but only time will tell.

I too am now noticing a delay\lack of SMS\Voicemail Msg after WEEKS of 2.69 working like a charm. I thought I was one of the lucking ones but now I am not so sure. Who knows how long this has been happening. Anyway, downloaded and installing right now.
Working great on WM2005 .
thanx Faria .
by the way...this is a US radio.....sorry i cant name the carrier at the moment.
I've installed this on my Cingular 8125 on the Cingular network last night. I received a test sms and another SMS from a friend in a timely manner. All test calls I've put through have worked so far. I was even downloading a webpage with Opera and phoned in and the call came through. So far so good... Tomorrow (Monday) will be the real test when I'm back to work, but I'll try to give it a workout today.
thanks for the info so far and please continue to post information on this rom and its working with wm6
P.S.-Sorry for not being able to also post information but in what i do missing a call/calls or missing a sms/sms' would cost me alot of $$$$$...(so thanks for being guinea pigs...poor pigs lol)
First timer dumb question
Hi. I am running Nottoosmart's system with radio 2.19. Things have been pretty stable, but there are times when I've had to reboot in order to reacquire the phone carrier after sleep (e.g. softreset). Also, subjectively I believe I have some signal problems when in places where there is already a weak signal.
So, bottom, line, I am considering trying this radio.
But, I have never flashed a radio before and I'd like to avoid having this become a "federal project." So a few questions:
1. I can flash the radio back and forth (e.g. ->2.40, ->2.19) *without* touching the OS (e.g. wm6 rom/ram), is that correct?
2. There are several executables in the zip: EnterBootloader.exe, romupdateutility.exe, RUUGetInfo.exe; I realize there are tutorials ad infinitum posted here, but can someone help me save some time by letting me know how to install the radio, do I just run "romupdateutility" over activesync, or is there more to do?
Please don't flame. I am an engineer, just not experienced in burning radios to MDA's. I assume the radio goes into a portion of rom that is dedicated to the phone processor of the OMAP chip?

Hello,
1) You can flash the Radio rom without messing with the OS. All of your settings and files will not be affected. It does not require a hard reset.
2) Just run the romupdateutility.exe. It works the same when you flash a new os rom, it just takes a fraction of the time due to the fact you are only flashing the radio. I just connect via USB and let activesync do its thing then run romupdateutility.exe, the program will kill activesync itself.
I hope this helps.

Does the Radio ROM actually affect the GPS?

Yes I have searched before you ask.....
I have installed the stock official Radio ROM (1.65.16.25) as well as the later1.65.24.36 version and now the 1.71.09.01 version that has recently been posted, all of which seem to be very similar for GSM performance.
Now I am not convinced any of them actually do anything to the GPS receiver. I have had really quick GPS fixes with all of the Radios installed and I have also had really slow fixes. There doesn't seem to be any real consistency so I am not convinced upgrading the Radio ROM does anything with the GPS, I am sure it does with GSM, GPRS, 3G & HSDPA.
Does anyone have any technical knowledge as to what actually gets upgraded with the Radio ROM and which systems does it affect (i.e. Bluetooth, GPS etc)? Not just observations and perception?

Cheers Dave I hadn't seen that post by viper. To be honest that was the conclusion I was coming to. I am pretty sure the differences in GPS fix times is just peoples perception and atmospheric conditions at the time.

After trying multiple radios I can say that radio definitely DOES somehow affect the GPS. How can be the different results from different radios explained then? How can I get the GPS fix with one radio in ~5 minutes and with another in ~15 seconds?
Strangely I have two Kaisers, at the moment both have identical everything and side by side the GPS fixes can vary greatly and it's not like one is always quicker than the other.
With regards to the camera being affected by the GPS? Again I think this is down to peoples warped perception.....

Yes Dave, I have previously read that thread, however I think the move from WM6 to WM6.1 required more fundamental changes - maybe memory locations affecting why the Radio ROM had to be a certain revision or later.
What got me onto this was all the replies about GPS (& camera) performance increases due to a new Radio ROM. With my experience I have simply not seen the monumental (as reported by some people) performance improvements (fix times) when I upgraded the Radio ROM
As I said I have two Kaisers side by side here, both with identical everything and the GPS fix times varies considerably between the two.
Andy
Interesting question - I was one of those who noticed real problems with my GPS after the original HTC update to 6.1, and had really poor performance for weeks. I then upgraded my radio to the new version HTC released as part of a revised version of the same ROM update (going from 1.65.16.25 to 1.65.17.56) and immediately noticed a definite improvement.
My GPS still isn't perfect, sometimes it takes a minute or so longer than I'd like to get a fix, but I can say that in the exact same situations, and over a few weeks testing with both versions, installing the newer radio definitely improved matters for me and achieved consistently better results. Of course there could be various other explanations, like the actual process of flashing a new radio somehow resetting/improving some unknown factor, but either way there's no doubt in my mind that the GPS is now more robust and reliable than it was previously, and the radio update really is the only variable in my case.
I know many may suspect some placebo effect, but for the record I did try a whole range of other supposed "cures" like running GPS Test, changing TomTom settings, hard resetting, flashing a different SPL etc etc, without imagining any improvement afterwards.
Sadly True
I have been flashing daily for 3 weeks now, sometimes multiple times daily, while on vacation to get the most reliable GPS signal for driving and I cannot upgrade to 6.1 roms because of the greatly slower fix times. I have tried ALL the newer radios, SPL's, fixes and tweaks, and the 1.27.XX radios still get the quickest fix and have the strongest reception. I have tried daily resets and gps cold fixes quite often to get an average time and heres my results. Newer 6.1 radios cold fix (first fix after hard-reset) around 3-5 minutes and older 6.0 radios cold fix around 2-3 minutes. Yes there were some short times and some longer times but that is the average of testing daily after flashing repeatedly. The difference is most noticeable when I use GPS Tool because it shows more details on the strength of the signal. The older 1.27.XX radio just seem to see more satellites right off the bat and the newer radios take 60-90 seconds before even seeing a single satellite. I am glad people are finally recognizing this as an important issue because I upgraded to this phone primarily for the internal GPS. Now that the kaiser driver problem is winding down maybe some great minds can work on this problem also.

It's true in this case about the oldies being goodies - I agree the GPS with WM 6.0 and those 1.27 series radios was ahem... miles better.
Why do I suspect that the 1.27 series Radios for WM 6.0 were provided to HTC by Qualcomm but they had to actually come up with their own for WM 6.1 - I may be wrong, it's just a hunch.

The interesting thing is that (I remember reading somewhere) aspects of GFX Acceleration can/could be coded into these MSM 7200 Radios so with both that and a once and for all GPS cure, the opportunities are immense for someone who knows what they're doing with Radio programming and development. Thats one reason why I was glad to see viperbjk has appeared here. There's no doubt about it as far as I can tell that Radios affect GPS performance and the proof of the pudding is in the eating.
This is guess work, without that much understanding as to the way the device performs GPS operations (or any other low level machine operations), so feel free to shoot me down...
Could the Radio "operate" at different speeds, i.e. the 1.27 radios process instructions/operations much faster than the latest 6.1 ones?
Could parts of the radio be indirectly used when performing a GPS fix?
If so this would mean operations performed during GPS by the radio, slow down actual GPS operations?
Just an idea
Dave
We might be veering slightly out of focus here - because of course, if you compare 6.0 ROMs (and radios) with 6.1 ROMs (and radios) then there's a huge number of not necessarily radio-related factors that come into the mix, not least 6.1 itself, and HTC's implementation of it.
Notwithstanding the fact that it's impossible to use 1.27 radios with 6.1 and vice versa, it could easily be argued that a 1.27 radio would not improve GPS performance on a 6.1 ROM, and that a 1.65 radio would provide excellent GPS on a 6.0 ROM - it simply can't be proved either way.
What can be said, is that when I changed the radio - and only the radio - on the same 6.1 ROM, I found the GPS performance had improved. Not so much that it equalled 6.0 performance, but a significant improvement in any case, and enough to prove to me that (in answer to the topic) the radio ROM definitely does affect the GPS.
GPS Speed
Not sure if radio effect gps but I loaded the D3D driver and these did slow gps lock down by a lot, removed driver and gps lock went back to being instant.
Hope this help.

Yes you are right that this example isn't a very strong case because there are lots of other variables. Just like you though I made that Radio only upgrade from HTCs initial WM 6.1 release to their latest one with only a different radio and noticed the difference straight away. For those who doubt the effect of the Radio on GPS performance, If everything else is the same (and the ROM itself is the same) what else could explain the difference in performance under the same sorts of daily use in similar weather and locations? It's crystal clear to me.
Well, for me, it isn't crystal clear
First of all, I do not know much about HTC so far, I just learned to understand what's going on. But regarding the radio, there is no difference in what I've seen so far.
Ok .... some technical explanations :
1. Radio CAN affect GPS reception as far as AGPS is involved.
2. Radio does NOT affect the way GPS is recieved.
Why ?
AGPS (MSM Chipset) can be used for getting
a) position fixes via mobile towers
b) recieve GPS fixation database via GPRS/EDGE etc.
This can speed up first GPS reception lock a lot.
But the radio does not affect the reception of the GPS reciever (chipset by infineon or surf I suppose).
GPS is normally controlled by WM driver. It could be controlled by AMSS (radio) but that is VERY unlikely because changes always have to be resigned (takes a lot of time) and gps-drivers would have to be reprogrammed for MSM chipset (very unlikely).
It will take a deeper research to be sure.
Comparing the same condition parameters isn't precise enough.
To be sure that radio driver affects GPS reception, you would have to disable radio by itself, especially AGPS.
Conclusion :
Radio can speed up updating fixation database using AGPS.
Radio can also offer faster positioning than GPS using AGPS, although not as accurate.
But as long as a surf/infineon gps chipset is used, there is no way radio speeds up or influences GPS reception in any way
Hope this answers some questions.
Cya,

It's a Qualcomm chip that drives the GPS. And who knows what a Radio does, what underlying functionality it facilitates. At this piont, I take it you were just guessing, viper?
Good guesses as anyone I guess, just wanted to correct you on the GPS. I wish it were a SirfStar III chip.

It isn't. The GPS baseband processing takes place in the main Qualcomm chip as shown by their product sheet. So to me it seems logical that the low level GPS processing code would be part of the radio firmware, therefore explaining the performance changes as they mess up with the code and possibly change their algorithms or simply the priority of the tasks the radio chip has to execute. Might be a power consumption issue too, as at least under the WM6 radios the current draw from the GPS is really significant, much higher than a usual dedicated (SiRF, MTK,...) chipset. Maybe they changed the SW under 6.1 to draw less power, leading to lower performance...
Also, as AGPS often messes up things (many people not being able to use the GPS anymore with it on), I'm pretty sure that all the users who reported different performance had it off anyway.
It could be controlled by AMSS (radio) but that is VERY unlikely because changes always have to be resigned (takes a lot of time) and gps-drivers would have to be reprogrammed for MSM chipset (very unlikely).
Click to expand...

To me the GPS code is as said in the radio firmware, and the actual HW drivers (given by Qualcomm) are compiled in it as well. Then, the GPS is presented to WM as a simple COM port i.e transparently so no particular driver is needed for WM itself. So the only part that would change when a change of behavior is required would be.. the radio firmware, confirming users' experiences.
Personally I still run WM6, and always get between 15 and 30sec fix times.
Small update :
For best evaluation of Sirf chipsets, I recommend
http://w5.nuinternet.com/s660100031/SirfTech.htm
I'll see if I can find anything similiar for Infineon chipsets.

Don't get me wrong, other programming aspects about this aren't clear to me, just the fact that the Radio includes driver code for the GPS and has a direct effect on GPS performance. As already mentioned by others the GPS hardware is within the Qualcomm chipset and is not provided by separate hardware.
First of all, I do not know much about HTC so far, I just learned to understand what's going on. But regarding the radio, there is no difference in what I've seen so far.

As I've never used AGPS (the native HTC ROMS without additional tweaking software have this turned off by default), I have no experience to report in this regard. I'm unsure what 2. actually means. I'm sure the statement "Radio does NOT affect GPS reception" would be incorrect though as in my experience radio changes alone can make big differences to how Tomtom and Google Maps behave. If the radio has different priorities or reduces the current/power available for GPS reception then it seems clear to me that this will alter the strength of GPS reception although maybe not the 'way it's received'. I see reducing the current available for the GPS hardware as a bit like reducing the diameter of a cars fuel line - it may end up being counterproductive. As long as the programming code results in efficient execution of GPS functioning, I'm happy for it to get all the power it needs. It's only if power is used to compensate for inefficient execution of GPS functioning that I'd have reservations about power consumption.

First GPS lock times were fine with my TyTN II in its original form and that didn't use AGPS. I'd be quite happy just to restore that level of performance again without relying on AGPS at all. I have started my TyTN IIs GPS up in some far flung locations where there was no phone reception at all and under WM 6.0, even then I had cold lock times of about 25 seconds as long as there was a clear view of the sky.
But the radio does not affect the reception of the GPS reciever (chipset by infineon or surf I suppose).
Click to expand...
Click to collapse
Maybe not when the GPS reception is dealt with by separate hardware but the TyTN IIs GPS is integrated into its MSM 720x chipset. Regarding your latest post, I doubt GPS functionality is part of the ATI Imageon type functionality in the MSM720x chipset, it'll be separate areas of the silicon that handle this (I presume thats what you're referring to with reference to infineon).
I look forward to what you may accomplish viperbjk when you become familiar with this hardware. The opportunities for someone who understands these chipsets and associated radio programming inside and out are huge.

ATT Tilt- possible radio problems, total noob needs help

Hi guys, I really did search first, I promise. I have been having connectivity issues (not making calls, lost data connections, etc...) since I updated to the ATT Official Windows Mobile 6.1 ROM (3.57.502.2 WWE) with radio version 1.65.21.18. I am trying to determine if I need to upgrade my radio version. I found the thread with all the radio versions for my phone but don't know anything about them. I did get that I should try different ones until I find one that works for me. So do I need to install the HardSPL on my phone (or did the Official ATT rom upgrade do that already)? From there do I run that RUU.exe file on the desktop (or what)? It would be great if someone could put this in super simple terms for me.
Thanks in advance,
-Max
one word for your info, "WIKI"
I did look over the wiki for some time, here is my hang up. Jockyw2001 posted in an SPL thread that "SPL3.56 is part of the latest AT&T Rom which is dated June 6. 2008" So since I did the official ATT upgrade and my ROM date is 07/17/08, does that mean that I already have SPL 3.56 on my device? I can not find a post about how to determine what SPL version (if any) is installed on my device. If SPL is already installed, is there any danger in installing an older version of SPL or reinstalling one?
Thanks again

So you are saying that the stock rom and stock radio are not working correctly, no cooked roms or other carrier radios?
Did the problems start right after you updated?
Oh and your problem seems similar to the one in this thread here, well least is sounds similar to me anyways...

Yup, stock radio and rom as suggested by ATT, whom their customer service now claims they do not support WM6.1. I've never used a cooked rom and really only come here for device information and applications. I did have problems before I upgraded the rom but they have much worse since. The thread you posted is similar but they mostly talk about an "H" connection. I am in the DC metro area (USA) and get 3G all the time now, I wonder if that is part of the problem, I never get an EDGE network signal anymore.
Well... I just found THIS buried over on the ATT support forums

I guess we just got 3G network here. I haven't been able to make/receive calls for 5 days now. Tech support supposedly looking into issue. My phone switches bewteen 3G and EDGE constantly. Anyone else having this issue? What was the resolution? I don't want a refurbished Tilt if they can't come to a resolution (why would I want the same darn phone if it doesn't work well with 3G as advertised?) I have already drove 20 minutes to the nearest store for a new SIM card..which did no good. There isn't anyway of turning off 3G network unless I install software I have seen mentioned on this forum and well, I don't know about that...I paid for this phone to do what it said, and it isn't.

And this is the reply to it over there....

Common problem that can be either due to problems with the rollout or that the local towers cannot handle 3G as effectively or at a greater distance as the same tower could for Edge. These are some related threads and posts but there are a lot more. As noted in these posts if there is a local AT&T store run by AT&T then you might pop in and confirm some of the problems with them.

The tendency is to blame the phone but the reality is often different and that includes from customer support who offered to swap my phone several times but this obviously would not work because it affected many other users as well differing phone manufacturers and models.

Timing of it is close enough to make me wonder, but I had been using HSDPA.. But I have been getting the same problems you are talking about when the phone is set to 3g as well. The other thing that is starting to make me think its something ATT did to their network is that the OP from the thread that I linked on here lives 20 mins west of my location, and I am 15-20 mins north of DC... I may go to one of the local att stores and see what they have to say (tho that means for me that I get to flash my phone back to the stock rom )

Massive reception dead spots (voice calls, data), possible 3G fault?

Please help. I have been with o2 now for a while and I’ve never had a reception problem this bad… I’ve brought my friends Kaiser. On T-mobile he had great reception around where we live and work but since I have unlocked it I have never had a satisfactory level of reception. I have tried lots of SPL’s, ROMs and radio ROMs (including the stock o2 one) and they are all as bad as each other, give or take. The number of bars of reception varies across the range but they all have the same massive dead spots with no radio reception at all. I have tried other phones i.e. nokia’s, samsung’s and a Hermes I had none of these dead spots.
Now here is where I may betray my noob status, I was beginning to believe it was something wrong with the o2 settings in general because it is like the phone is only picking up reception from certain cell towers (maybe o2 ones?!?) and ignoring others, is this possible or am I just grabbing at straws? Then I discovered a most promising the thread http://forum.xda-developers.com/archive/index.php/t-335074.html which is full of people with 3G faults perhaps my problem is linked to the 3G mast nearby and so in fact my phone only works where there is a poor signal and no 3G which forces it to use GSM. I have tried to prove this but my current ROM Mobile Vista 4.00 SeaDragon 5.2.21109 seems unable to remember the GSM setting, the phone locks up and require a soft reset. I am sure it can’t be a hardware fault as suggested in the above thread because my friend had the phone working flawlessly.
Any suggestions as to what I can do. I’ve been at this problem for over 4 months now and am close to admitting defeat, I believe the problem may be beyond me...
I believe you should be posting at General Kaiser Forum instead
My strongest suggestion is go back to factory (OEM) including the SPL and ROM, so you can be sure it's not ROM/Radio. If that's ok, then you need to carefully match the Radio/SPL/ROM. Some radio is only for WM6.0 (check the Radio FAQ, included on the sticky FAQ thread).
Ok I have made a bit of progress but would like some advice. Now that I am aware of the 3G fault I have been keeping an eye on my signal and each time just before the signal dies the phone is trying to switch from gsm/edge to 3G/HSPDA. I have flashed my rom again this time with a reconstructed T-mobile UK rom that I found through the revert to original rom and SPl for waranty returns (Thanks a lot jcespi2005). I now have a 3G/H signal (phew atleast my phones not bricked) but am unable to make or receive calls, I assume this is because it is set up to use T-mobile settings not O2. Is there a cab out there that would let me change the settings for the OEM operator rom so I can keep this working rom. Failing that does anyone have any suggestions for a cooked rom for O2?
