R1BC002 ! This is a new FW ? after R1AA008?
yes
update using SUSE if u have a w800 and it tels u that its not necesary then press continue anyway
worked for me

The most common pattern of joystick failure on my phone goes like this: Joystick fine until play some games involving heavy use or extended period of play. Then afterwards joystick in phone menus etc unresponsive. Then rotate joystick in all directions backwards and forwards for about 10 rotations. Joystick then working perfectly, and stays working until play games again. This entire process is independent of how much dust has built up around the joystick or whether it's been cleaned or not.
When you say rotating do you mean in a circular motion or just up and down and left to right?

Around in circles, but in all directions as well. The point being to register the full range of motion of the joystick in the auto-callibration software (if it exists).
To mongoose3800, I have hardware experience in most areas of consumer technology (well I really mean I have pulled apart most things
) and I can tell you the auto-callibration is more than possible, infact many joysticks use software callibration.
I am not talking manual re-calibration of the mechanism itself. What we are talking about is software that continually monitors the joystick movement to make fine adjustments to the joystick's registered range of motion - no hardware adjustment of switches, springs or levers are involved in this process.
In fact all joysticks need software callibration, which can be done easily either on demand or automatically as the device is used.
You could also read my posts properly to see the reason that dust build up does not explain the joystick problems, which therefore strongly suggests the possibility that auto-callibration is going on.

MAX_Wedge - I work with computers and like you have been pulling things apart for many years just to see how they work. I agree that dust getting into the joystick can cause problems. You see dust affect all sorts of micro switches in all sorts of devices. But, I disagree that there is any calibration of any sort on the joysticks of the K750 or W800. The reason most real joysticks need calibration is because they use variable resistors or optical sensors. This gives them a progressive range of motion not just full right or full left and so on. So, with real joysticks calibration is needed to obtain the maximum and minimum values/voltages and to tell the software what combination of these values means the joystick is centred. The joysticks on these phones are very much like the old joysticks on Commodore 64's - They were made of nothing more than 4 switches. The really good ones used to market the fact that they used micro switches. And, you never had to calibrate C64 joysticks – it just wasn’t needed. Move the joystick on your phone in the keyboard test under the Service menu. You'll see it only gives 8 motions. Which happen to be the result of the full range of motion made possible by 4 micro switches. You'll never see a case whereby you can control how hard you turn right or left on these phones. As with a C64 joystick - calibration is not needed with these phones because the phone knows the joystick is centred when all 4 switches are off. I hope this makes sense.

Guys,are we going far away beyond the original thread? Is R1BC002 the final f/w?

mongoose3800: What you are describing is the differnce between a digital joystick (the C64 on/off) vs an analog joystick, which first showed up with the 1st MS Sidwinder more or less. A digital joystick registres just on/off position, while an analog one has a sort of potentiometer which 'measures' the amount of feedback you give it, while a digital one just measures contact (on/off). At any rate, the joysticks on all phones (as far as I know) are all digital. Not many hand held devices have analog joysticks, with a few exceptions such as some pda's like the tapwave zodiac.
I'm going to upgrade to the newest firmware tomorrow (hopefully) and see how well it runs. My BIGGEST problem with my phone (K750i) is that it literally crashes about once every 2-3 days and it needs to be rebooted. When I say "it crashes" I mean that:
1) wallpaper (animated) will disappear and the screen turns gray
2) animated icons in the menu turn into BLACK SQUARES when icons are highlighted
3) java games start giving "Not enough memory..." errors.
Not sure if this issue has been addressed before but no firmware so far has fixed that for me.

that sounds terrible... what did the SE guys tell yah? didnt they found a fix?
a phone acting gaga needs to be replaced.

I have been testing for a couple of days and haven't come up against any issues. Bluetooth works fine, no cable transfer bug, no crashing or restarts.
Video is AWESOME (compared to the R1L002 I was on), and the camera speed is a marked improvement. I'm stoked.
@mongoose, actually even the old analog on/off joysticks on pc's had the ability to be calibrated. All I object to is the way you discounted the idea with the statement "Also, I amazed that some claim the F/W fixes issues with the joystick or think the joysticks are calibrated"
It seems to infer a level of stupidity, and since I had a very good reason for suspecting auto-calibration (explain my pattern of use some other way - dirt in the joystick doesn't fit) I feel you haven't justified your point well enough to be "amazed" that I might claim such a rediculous thing.
I am not claiming that it is 100% certain that the joystick is auto-callibrated - It just seemed to me like a viable possibility to explain the use patterns I am getting.

Slight problem with that... The phone was purchased under contract by O2 from Germany, but is in use on a different network in the US. Not sure if there's any service that SE can provide for me in the states... Ideas?

you could also try if you haven't already (and if the update doesn't help) the following possibilities:
1. Format memory stick (especially if all the above files you mentioned are on mem stick)
2. Delete all user content (backup first) and then do a master reset. My R1L002 crashed twice just after I'd updated to R1L. I did a master reset, and it hasn't crashed at all since, 7-8 months ago.
3. When you update, remove your memcard. (some users, myself included) have gotten corrupt memory cards after an update where the card was in the device while updating.
