Reading the forum I came across people referring to "repair.zip". Apparently it was helpful in recovering from "GSM- ERROR"
Where can I download this zip from?
Any hints would be appreciated.
If you are still looking for it I have uploaded it here http://www.gsm-info.co.uk/public/

I could not fix my XDA and was getting anywhere so eventually I had it repaired.
However this may be helpful next time and others may find this useful now.
Thanks a lot
No worries.
What are the symptom?

This sounds like it might be useful given the problems I am having with my phone, but before I try it, what problem exactly does this repair.zip solve?
My problem has to do with extreme system-wide slowdown, a soft-reset that takes 20 minutes, and the dreaded "GSM Error" at the Wallaby bootloader screen.
Thanks,
-Jason-
The problem with the GSM error is a nightmare, the GSM side of the XDA etc etc has from what I can see all the battery controls as well, so if the gsm side is F**ked then you have no way of charging the battery which means unless you have something like 70% charge in the battery no matter what you try it will not go past the 1% error part, so unless this has just happened on your phone you are stuffed might as well send the unit to service center to get repaired, at the moment I have 2 units with gsm error and can't do a thing with them, I'm trying to get hold of a good battery to see if I can sort them out or find a way of charging the battery off the XDA.
I'm glad I came here, I have the same problem, and last night, I had that 1% error, and the hint from lonegunman is very helpful, I have a Cadex c7400 battery analyzer, I don't think there will be a problem with charging the battery.
In general, you will have first to disassemble your ppc, (four screws in the back, then slowly apart the two sides of the cover with a strong thin knife like plastic tool) look at the battery, in my qtec, it is the far left and right terminals that are for charging, but as I didn't test this yet, so it is very much possible that you will need to connect the ( - ) terminal to one of the in middle terminals to close the circuit and to be able to charge (I will test and post back).
You can use a normal 500 - 1000 mah / 5 V charger, depending on your battery capacity, you can determine for how long you need to charge it, If your battery is 1500 mah, then it will charge in about one and half hours using a 1000 amh charger, if this is the case, I advice that you don't charge it for more than one hour and 15 mins, lithium/ lithium polymer batteries are very vulnerable for over charge, and for over heat, if the battery gets too hot to be touched, stop charging immediately (temp must not exceed 60 c). If you find out that the charge is not enough, add 15 mins at the time. Lithium batteries does not suffer from what is known as memory effect and can be charged when at any level of charge (you can charge it when not full, almost full ... but this will affect the life count of the battery). This also may be useful for any one who has a spare battery that is not in use, lithium batteries must never be stored empty. Also please not that life span of a lithium battery is around three years when used properly.
Now I have a question, is it normal with GSM error that I can't connect my ppc to the computer via the USB and activesync? because this is what I have, I can only use sd card but not the USB connection.
OK, now after I tested it, you can charge your battery by connectong the charger to the far left and right terminals of the battery, in qtec 1010, they are the bigger terminals. It is preferable to use a charger made for charging lithum batteries.
HI!
This might be a stupid question...
During the day my O2 Mini is always connected to my laptop thru the USB sync wire and therefore its keeps getting charged.
Is that in any way harmful for the battery...does it reduce battery life over the long run??
Thanks.

No not Lithium Ion batteries. In fact it is better to charge the battery as often as possible.
is that fact? i cant believe it.
It is the way the battery is designed, there is logic in the battery that cuts off voltage when the peak is reached as far as I know.
Thanks cruisin-thru and skjelnes .
If you let them go flat for any length of time, they die completely.
USB charging control
Still this whole battery charging and technology issue is quite ambiguous. No one can really guarantee that there is a clear answer. For instance why do you have to give the battery an initial 8-hour charging if it is a new generation battery?
In any case it would be interesting to know how the charging control works. There are some options:
- It can be controlled by a circuit which cuts off power at a certain level of charge (no way to play with this option).
- It may be controlled by software which would be great because one could (easily) interfere with it. In this case there must be some kind of relay switch controlled by the operating system.
- It could also be not controlled. In this case the battery never stops charging. Only the indication changes when a battery meter reaches a certain level. This looks more likely to be the case as the initial 8-hour charging might mean keeping the battery under voltage during the initial charge as even though the indication states that it is fully charged the charger is not disconnected by any control system.
Does anyone have some solid information on the above assumptions?
Note: I tried to isolate the power pin of the USB cable in order to prevent the device from charging but then it was not recognized by the USB (got a USB connection error). Obviously the power line of the USB is used for connection and signal as well and not only as a optional power supply to the connected device.
I'm currently trying to find something in the registry about charge control....
Maybe Microsoft has hidden a secret option somewhere in there... :?

A litium-ion battery gets worn from three things:
* Normal use
* Heat
* Full charge
A short while after the Ipod battery dirty secret leaked, I read why the batteries only last for like a year. A NiCd battery HAS to be cycled completely to last as long as possible because of their memory effect. A NiMh battery LIKES to be cycled as completely as possible for longest life.
A Li-Ion battery does not have the memory effect - therefore a lot of people seem to assume that you can charge a Li-Ion battery any way you want. That is not correct... Everyone of you ever used a laptop with a Li-Ion battery every day at work, with the ac-adaptor plugged in knows that the battery is ready for garbage bin after one or two years.
Why? You've almost never used the battery... It's always fully charged... The battery should have lasted much longer you think...
Isidor Buchmann is president at the company Cadex which makes battery chargers. He has got more than 20 years of experience from the battery business.
At the site: http://www.batteryuniversity.com he has written an article where he explains the mechanisms inside a Li-Ion battery and provides tips about how to treat the batteries.
Finally he gives the following advices:
*Don't discharge the battery completley. It's better to discharge the battery a little more than halfe than making a complete discharge.
* Discharge the battery completely and then charge it completely to calibrate the battery meter
* Keep the battery cool
* For long time storage: keep the batteries charged at 40% in the fridge
* Do not use the ac adapter and the battery when the battery is fully charged. Heat and unneccesary charging after the battery is fylly charges destroys the battery
My 2 cents.

I think most questions have been answered, except Magician specific ones, i.e.:-
The Magician has to be initially charged for at least 8 hours to:-
1. Make sure the main battery is fully charged and formed, and charging logic calibrated (future capacity depends on this)
2. Charge the backup battery. Unlike the main battery, this only gets a trickle charge which starts after the main battery is at 100%. So it needs those 8 hours to get to full capacity. Remember to do this if you ever drain the backup battery.
Lithium charging logic is built into the battery, so no way to tamper with the settings. The NiMH backup battery logic will be built into the Magician.
Very interesting reading! I didn't know about the issue with laptop batteries.

OK we can easily avoid discharging the battery below 50% or 60% at normal conditions even when traveling through a USB port of our notebook (3rd quote)
We should also avoid a USB connection at a 100% (2nd quote) or even at a 90% (3rd quote) charge level unless we can find a way to cut off the power supply to the battery. The only option would be to find a way to do this from the device, before the internal logic of the battery. As far as I can understand the internal battery logic allows charging whenever connected to a power supply and it only informs somehow the device of the charge level.
OMG.
All this nonsense about batteries.... it's easier to just buy a new battery or a new device after 18 months, rather than let your charging habits be dictated by how batteries like to be tickled!
Easier yes, more expensive too.. Dell sure knows how to charge (!) you for a new batt with built-in subwoofer..
Does it matter if we don't charge it all the way till it's full? If I'm charging it till about 95% and I really need to unplug it. How much damage will it do to my battery?

I'm not following you - I think. If you unplug it at 95% it's a lot better than unplugging it at 100%.
Summary:
Full charge: BAD
Full discharge: BAD
Heat: BAD
Extreme cold: BAD
// Anders
This is the first time that I ever heard that charging up to 100% is bad. I know that leaving it on the charger for extended periods is bad but to say that charging to 100% is bad.. that's absurd!!! :shock:
I need some help.
I want to turn on/off the usb charging for my MDA pro from T-Mobile.
I find here in the forum the following key
"HKEY_LOCAL_MACHINE\Drivers\BuiltIn\usbfndrv".
But this key does not exist in my MDA pro. There is only the key
"HKEY_LOCAL_MACHINE\Drivers\BuiltIn\usbfn".
Do you have an idee how I can turn on/off the usb charging anyway?
Thanks for helping.
Barlow
AFAIK the USB port is the only way to charge your Uni.
It doesn't make any difference to the operation of the device if it is charging, you can still set it to turn off after a time, you can set the screen brightness the same as when running on battery.
I would imagine that (and if I'm wrong, please tell me) the charging circuit is hard wired into the port and the battery so that you can still charge even with no OS on the device.
Is there a reason you would like to disable charging?
I want to turn off because otherwise the device will always be charged, not charged because I not always sitting on my pc and then I use the mda and when I come back I sync againg.That's happens a lot of time a day!
Do you know any registry key where I can turn off charging the device overt the pc?!
Topping Up is Better
There are a million threads about charging and this is sure to provoke flaming but here goes anyway.
You are better off topping up the battery frequently than running it low and recharging. The 'limited number of charging cycles' does not mean that you are better to run it low and recharge infrequently, but instead refers to the fact that with use the battery will degrade. Charging on your pc -- topping up -- reduces the impact of use slightly, but it is primarily battery use that matters.
There is some evidence that a monthly deep cycle will help, but for day to day use, topping up will *extend* the life of your battery. Note that there is no memory effect as exists with NiCd batteries, which were degraded by topping up.
Ok I am a new member to this whole PocketPC thing since I just purchased my first PocketPC which is an i-mate JASJAM. I honestly think that it's a great product with a lot of features and potential. My problem though, lies in the fact that I haven't had the chance to enjoy it for a full day yet. Ever since I bought it, I always charge it for like 7 to 8 hours, even though it fills up after like 3, but i leave it on charge anyway, because I was told that "that's what you should do!".
Anyways, no matter how long I leave it on the charger, once i take it off the battery begins to drain like there's no tomorrow. I'm talking about going from 100% to 0% within 5 hours, while on FLIGHT MODE. If I turn the screen off then it might last for an extra hour.
Surely this can't be something normal, and I have been beating my brain trying to find a solution. As far as ActiveSync goes, I did the tweak that stops its automatic scheduled syncs, hoping that it would be the problem, but to my disappointment, no luck. Also made sure that no programs were running in the background. It came with a battery with a capacity of 1300mAh and then I bought another one hoping it was a problem with the battery. The new one had a capacity of 1350mAh, not much of a difference but it was all I could find. But there's no difference between them whatsoever, when it comes to battery life.
My first question is whether it is possible that this may be a software issue rather than a hardware issue (such as a power leak)?
If it is, then would upgrading the ROM or Radio or upgrading to WM6 make any difference?
Problem's that I don't have the phone on me right now so I can't give ROM or ExtROM versions etc., but I do know that it is running WM5 with AKU 2.3 and Radio is either 1.21 or 1.31.
N.B.: Until I get this issue sorted out, I am using a Nokia 6680 which has an average battery life of 3 days (72 hours), so should I be expecting something in the vicinity with my i-mate?
Well it sounds as if you've done all the obvious things. There is a power saving registry tweak in the wiki somewhere but that should not be necessary just to bring it to normal power consumption. If I don't use mine much (not on flight mode) I'll get a couple of days at least.
A ROM change might help a little but if you have a warranty I'd be tempted to use it. Radio change is unlikely to change things if you have been testing in flight mode.
Anybody else got ideas?
Mike
The only problem that I have with getting it fixed or replaced under warranty is that I have to send it to another country. So I am trying everything I can do before going through that hassle. So is there any test that I can carry out at home, or a certain diagnostics software that can test the phone for me?
Would a digital multimeter help if i can measure the current being drawn from the battery? What should the current rating be for the phone, is it 1A? Because there is one other interesting thing i found while just snooping around, there is a sticker that just has 5VDC and 1A written on it, and it's stuck to the phone under where the battery goes. I can only imagine that this is the voltage and current rating for the phone. The interesting part is that the battery that came with it, as well as the one i bought are both 3.7V batteries.
:-S
Best to just update your phone.... But becareful! read and research on flashing b 4 you do it... VERY IMPORTANT... USE only softwares for your phone...
I wanna make sure that anything i do doesn't void my warranty as well.
Used their offical update for your phone... However, my friend brick his phone and sent it back to the company and they replace it for him... I dunno if you would have that luck however... if ur careful and read all the information... and ur computer is stable... you shouldnt worry about it bricking ur phone...

The ratings you see written inside and the battery ratings are just standard - nothing unusual there. You could test current draw etc but even if you find it a little high it doesn't really help you to pin down a problem save to say it's the phone and not the battery. However as you have two batteries it's fairly reasonable to say it's not the battery. (reasonable but not impossible of course that two batteries are not working as they should).
Unfortunately we do not yet have our hands on the test file that HTC use.
Mike
I guess I have no choice but to get it shipped back. Thanks for your help guys.
Are you using a wall charger or a trickle-charger such as the USB Cable? The wall charger is the only way to truly charge it to full.
If you are using a USB charger or other trickle charger, after the device says it is fully charged remove it from the charger for about 2 minutes and then reconnect it. It will then charge (most of) the rest of the way.
If you don't do this, the problems gets worse and worse. After 1 day, the trickle charger may get you up to a 90% charge. After two days, 80%, etc. After a week you'll only be holding half a charge, even though the device is reporting a full charge while on the charger.
Another tip I have found is to perform a soft-reset after removing it from the charger, particularly if it has been plugged in for a long time at full charge (more than an hour or so). It seems like the device doesn't always detect that it has been unplugged and tries to suck down juice as if it were still plugged in. If you have noticed that your device gets pretty hot when the battery drains quickly, this is probably what is happening to you.
You also haven't mentioned the programs that you are using during the day. Some programs, particularly chat clients, will drain the battery in about 5 hours, though obviously you're not using anything like this while in flight mode.
One more thing. You noted that you were told that leaving it on the charger whenever possible is the thing to do. This is incorrect. The more the battery is exercised in this way, the shorter the lifespan of the battery will be. With any PocketPC device we're all bound to charge it every night, but once it is charged you want to take it off the charger. A battery being fully charged is just as bad as a battery being fully drained, so you want to keep it somewhere in between as much as possible.
My battery doesn't last either.
I've ordered an extended life battery with its own back.
I've also ordered a car charger.
I also carry my old hiptop with me when I need to switch sims.
Apparently touchscreen phones that do so much, ie. bluetooth and wifi, eat batteries.

Wow, I am very surprised to hear some of these. First of all, are you sure that using the usb charger kills your battery capacity so fast? I mean, I almost always charge my phone with the usb charger and it seems to be quite fine. Of course once in a while I charge it with the wall charger when I am in a hurry. But I was thinking that charging it with the usb will be better as it charges slowly.
Also I usually keep my phone plugged to the usb. Indeed, I already ordered a desktop cradle so that I can see the screen while it is being charged. Is it a bad idea to keep it cradled all the time? This is what I did with my Dell Axim all the time and it was quite happy with it.
The process of charging/draining modern batteries won't shorten their lifespans. However, having a chargable battery at full charge or at no charge are both bad and both will reduce the lifespan of the battery.
So no, you shouldn't leave it plugged in/cradled all the time.
The problem with trickle chargers is altogether different. They just won't always charge a battery to its full capacity -- so in this way they are actually better for long-term battery health. This is why I said that if you want to get a full charge off of a trickle charger, you have to (usually) take it off the charger and put it back on when the device reports that it is fully charged. After unplugging the trickle-charger you'll get a new battery reading on the device which will usually be anywhere between 60% and 90%. You can then put it back on the charger until it shows full again.
Deleted, invalid, i didnt read the whole post.
Well, it seems that i was just unlucky with my buy. Thanks to all of you first of all for all your support it really did help me learn more about PPC's in general, and it also made me sure that there is a problem with the phone. I sat through what i like to call a debugging session, just following the phone's every "move". I know, sounds kinda crazy but i was just that determined. What i realised was that whether i performed the soft-reset or not, it still had a problem, even though the solution did sound very promising.
This is what happened, charged it to 100%. I also tried charging it a little more later, but that was it, so i'm pretty sure that the capacity was right. After detaching it i performed the softreset, hoping that it would help. Then i just left it over night on flight mode. Next morning it had only decreased to 90%. GREAT! And it felt rather normal, but then about an hour later, it jumped down to 80%, 70%, 60%, then 50%. Then when I held it, it felt pretty hot, i figured that whatever was the problem earlier, just happened again. So I turned it off for a few hours then turned it on again and it started off on 40%. As before seemed to be performing quite normal, then within a minute it heated up again and jumped down to 20%. And that was when i just lost my nerve and packed it to send it back to my retailer.
I am now convinced that the phone is faulty!
Yes, it very well might be.
My device has drained suddenly a few times, with the exact same heat problems that you're describing when it happens. A soft reset for me when this occured fixed it -- and it hasn't happened for months.
But as we all know the same solutions don't work for all people with HTC devices.
I just had the same sort of problem. I've been using my TyTN for several months now under Dutty's WM6, and only just flashed Schaps 3.60 a few days ago.
It worked fine the first couple of days, but now I'm having the dreaded 5hr battery life too.
I had had that a couple of times before, but it was always related to some software, and a soft reset would cure it like Doom Tints said above. The problem is that here, either this or a power-off and reboot doesn't change a thing.
It's clearly a software problem too. I use UpTime Meter from AE, and I can see that the PocketPC simply doesn't turn into standby mode, but only deactivates the screen. In UpTime, the power on time will always be equal to the time since last charge, which means the PocketPC is on all the time. In that case the 5h battery life makes sense.
Would there be a way to find out why it doesn't enter standby mode (which software blocks it up), or force it into it? It would be good to find something as I'm nearly sure this is the reason for most if not all of the cases of short battery life we see around. Without having the meter there's simply no way to realise that the thing just stays on...

Since I had my hermes, a few times it would get very hot and discharge the battery, and I assumed I was turning it on in my pocket and running a program. But now it does this continually. As soon as I take it off the charger it discharges and gets hot. This even happens if the phone is powered off.
I have borrowed a battery of someone else and the same thing happens
I have also hard reset it and have nothing installed extra, so it can not be software problem.
Must be a short circuit inside the phone? Does anyone have any ideas? I can't send it back as it is a Cingular and I live in the UK and have no support contract.
Thanks,
Mark
I managed to investigate and find the culprit - A2DP Toggle in my case. Whenever its Today plugin is enabled, it will prevent the phone from entering standby. Deactivate it - no uninstallation needed - and it returns to normal. Weird as it had been working perfectly for about a week, and I haven't done any change when it started acting weird.
Now it kinda defeats the plugin's purpose if I have to deactivate it everytime...
@simkin: If it drains the battery even powered off completely that's most likely a hardware problem. Does it happen too if you remove the battery and put it again without turning the phone on (as opposed to having the phone on and turning it off with a long press on the the power button)?
There could be a slight chance that the phone actually starts booting and gets stuck there draining power. As a last solution I'd try flashing it with a different ROM, but if that fails it's most likely a hardware fault.
I'm having battery trouble too, I switched to WM6 with a full battery that lasted for about 24 hours and it became 7-8 hours, so I switched back to my previous ROM and Radio ver and it still says I only get 7-8 hours average, I'm gonna try to hard reset it on more time, and then i'm just gonna try a new battery.
Hi all, there is a way to turn off the charging function when using USB ,
1-install FdcSoft TaskMgr from here
dotfred.net/TM/FdcSoft_TaskMgrv3.3_WM6.5.cab
2-go to Devices--->$device\BAT1(BAT1 and stop this service
3-thats All
To Use charge restart this service
hey thx for the tips! but after stop the service my o2 keep saying batt low...
Is there any reason why we would want to turn off this service?
I heard that it keeps your battery in good shape

I'm not so sure about that... I've always charged both my O2 and the O1 before through usb and the battery has always been fine.
Actually, I even noticed that charging through usb takes longer but once it's charged it also lasts longer (this happened on the O1, haven't made the same comparison on the O2 yet)
Dunno if plugging / unplugging the usb cable too frequently can have some sort of ill effect on the battery life, but it's not like we're plugging it every 10 minutes is it?
Never had a battery problem with a "normal" usb usage and usb charging enabled so far...
Yes but not anymore

I heard that it keeps your battery in good shape

It's always good to drink all the juice so the battery don't develop a offline or fake "memory".
Also the multi cell assembly insde the battery praticly don't allow batery memory anymore.
Thx for the reference
Regarding battery life
Hi,
Actually, for a battery it depletes it's life every second. There is no way of preventing this But we can extend the service life. For example the most basic rules:
1-Do not charge your battery unless it is almost empty
2-Avoid deep discharging (this is not possible with a PDA coz it has an early shut down routine)
3-Do not overcharge the battery (also this not possible, coz there is a voltage limiter by hardware)
4-Do not leave your battery in a high temperature environment (for example in a car during summer, we are using chemical-reaction batteries)
the rest is do not puncture, do not short circuit boola boola boola
ok, finally while using your PDA with a USB charging interface, it should stop charging when the battery is full (Even my mother's old nokia doing this)
Plus, how much it costs for a new battery? only few bucks.. ehh.. (not for an original one ofcourse)
PDA batteries, in most cases, are 3.7volts (charging voltage is 5volts by USB) and 1200 to 1500mAh (for the ones who doesnt know what is "mAh": it is the capacity of the battery and it means if you pull for example for a 1300mAh battery, 1300 "mili ampers per hour" it will deplete. Some of my friends they are using 3.7V 2000mAh batteries while their PDAs supplied with 1230mAh batteries, thus, standby time goes up to a week. They are not using their originals ofcourse. I dont understand why manufacturers are not supplying PDAs with these kind of batteries by standart. Even a chinese made battery can be so efficient. (I am using a chinese one, my original battery is 1300mAh, i could find 1500mAh same battery)
I spoke to my friends, they are not charging their 2000mAh batteries via USB/charger while battery is in the phone. Because there is an internal electrical resistance of every battery. May be PDA's battery charging circuit get damaged! Because of this if you plan to use a high capacity battery, charge it seperately by using another charging equipment.
Finally when you want to sell out your PDA install the original battery (which you have never used before hehe ) and get a higher price
This might be some really big idiotic question, but what if the service is down and the battery drains and the phone shuts itself off, will it turn on by connecting the charger to the phone?
I ask this because with the service off even the real phone charger wont work (at least while it is on)!

Hi all, there is a way to turn off the charging function when using USB ,
1-install FdcSoft TaskMgr from here
dotfred.net/TM/FdcSoft_TaskMgrv3.3_WM6.5.cab
2-go to Devices--->$device\BAT1(BAT1 and stop this service
3-thats All
To Use charge restart this service

I just did what you said, and now the device\BAT1(BAT1 completely disappear! How am i supose to turn it on again now?
And no, i obviously didn't delect it, i just stoped the service and it vanished from the damn list!
im very interested in this but how can you restart the charging service?
