Lol. That was going to be my next question: "How updated is your computer?"

I've seen - in other cases - that all kinds of errors get shot around when various drivers, OS or BIOS aren't updated.

I remember reading a couple threads about this problem and updating seemed to be the fix-all.

Try to make sute that EVERYTHNG that can be updated, is, then try it again.
[Upgrading, Modifying and Unlocking] Quigley:
Well, since updating the BIOS did not work, I tried it on my other computer, which is essentially the same but has a slightly different motherboard. Now after installing WMDC and resetting the device, the driver installs correctly. Device Manager hasn't a single error on any of its devices... BUT in WMDC there is no indication that it is connected! It just displays 'Not Connected". Any idea what I can try next?

Thanks for the input so far!
[Upgrading, Modifying and Unlocking] DJAnt1320:
Try holding down 'Reset' on your device while it's plugged into your comp. That worked for me.

*** Edit: Look in my sig and grab the USB driver(s). That might help, as well. ***

mio P550,

A few questions:

- What version of windows mobile are you running?

- At which point did the screen freeze?

- Did it happen after you flashed a new rom or it suddenly freezes with no apparent reasons?

- Did you try a hard-reset?
[Upgrading, Modifying and Unlocking] mio P550:
Thank you for the reply,

It’s all new to me so you won’t be able to over-simplify an advice you have.

It has the original Windows Mobile 5.

The screen originally froze while running TomTom but afterwards would freeze at any point usually within a minute of starting. After turning it off with the slider and leaving it a few minutes it will start up and run any of the programs. If you then turn it off using the front button, when you return it won’t respond – you need to turn the slider off for a while.

I’m not certain what a Hard Reset is – the one I’ve done is Start >settings > system > system info > clean boot.

I have the firmware ready on my desktop to do the re-load but thought I’d wait until I learned more before trying.

Two more questions …

Is it possible to use an SD card rather than USB for the new ROM ?

While I’ve downloaded the English v6.5 (Edit: Should read 6.1) to the desktop would it be better to get the machine running properly on v5 before upgrading it?

Thank you again,

Ray

[Upgrading, Modifying and Unlocking] jvchawk:
Ray,

In my knowledge, P550 has been first shipped with Windows CE 4.0 then with CE 5.0. There is no official update to Windows Mobile 6.1 or 6.5.

There are however a few versions "cooked" based on Windows Mobile 6.1 or 6.5 . For WM 6.1 you can find both the English and French version. For WM 6.5 only the French one.

Hard-reset is when you return the device to the state when the box has been first opened. In this way, you will loose all applications you have installed later on like TomTom. How to? By sliding with the point of your stylus the ovale hole at the bottom of the device to Off, let it in this Off state for 2-3 minutes, then slide it back again to On position. If you continue to see things exactly like before, that means you have to let it in Off position for longer time to allow the device to unload its memory.

For Soft reset, just insert the stylus point into the tiny round hole at the bottom of the device and press. It helps to unfreeze the device and you still have all your installed apps.

There are 2 ways to upgrade the rom on this device: Via a SD card (most used one) or via USB with additional USB driver to install on your PC. When you install via SD card, you'll have to:

1. Extract the rom file using 7-zip or WinRAR

2. Copy the 'winceimg.bin' file to your SD card.

3. Insert the card in your device

4. While holding the joystick button down, soft reset with the stylus point

5. A blue screen comes up (Bootloader). Use the joystick to navigate up and down:

6. Choose '0= Image Upgrade Tools'

7. Choose '1= Image by SD/MMC'

8. When the process is done, soft reset with the stylus point

I do not talk about USB flash as it has been already and largely discussed on this thread.

When you flash a new rom, it erases the existing. No need therefore for the existing version to run OK before flashing.

If you really have WM 6.5 in English (?), thanks to share.
[Upgrading, Modifying and Unlocking] DJAnt1320:
Great response, man!

I've emailed a couple people regarding this same thing, but I must say that this was pretty efficient!

No kidding, to Ray: If you have 6.5 in English, It'd be a great thing to share it! I went from the French version of 6.5 to the English version of 6.1, just so I could read it, but having 6.5 in English would be primo!

Regarding Hard Reset

I’ve been using the slider on a regular basis to overcome the “power on” problem – Mine won’t restart after using the front button – the only thing it loses is the time. In the manual it says the slider is to take it back to the last state when the reset button fails.

Someone kindly sent me the firmware file including.

Firmware_R05_mioP550

MioP550 - Osc260A R05_P09.nb0

dnw5.0e

dnw

Plus the USB driver folder.

I changed the name of the MioP550 - Osc260A R05_P09.nb0 file to winceimg.bin put it on the root of a 4GB Sd and it would only get as far as ...

MountDisk Success Open Whole Image

Edit:

Since found I had the SD card formatted to FAT 32

Reformatting the SD card the file loaded automatically

Unfortunately it still freezes after a short while.

Any suggestion what to try next would be appreciated.

Thanks

[Upgrading, Modifying and Unlocking] jvchawk:
Ray,

It is normal that it failed as the max SD capacity Win CE can handle is 2GB. Try with a 2GB SD or even 1GB. Format to FAT first.

Keep the 4GB SD to when you have 6.5 installed.

For MioP550 - Osc260A R05_P09.nb0, I think I have seen it a few years ago and it must be Win CE 5 if I'm not mistaking.

More answers:

Was changing the file name the wrong thing to do? No. You did RIGHT.

Is there a different firmware file which includes winceimg.bin? None of the official ones. Except the one in your hands

Is the file I’ve been sent specifically for use with USB? No. Can be used with both methods

Is it important to use 7-zip or WinRAR … I used WinZip? No. Winzip is OK.

Problems

It rarely re-starts using the front on/off button.

Always needed the slider turning off for a while to get it to start.

Never had the Mio “power on” patch installed, wouldn’t load when I tried.

Running OK for a year then froze on TomTom7

Then froze on any screen, usually after a few minutes.

Loaded MioP550 - Osc260A R05_P09.nb0 using 4MB SD on FAT16

It still freezes.

Questions

1. Has anyone succeeded in solving a screen freeze problem by loading the MioP550 - Osc260A R05_P09.nb0 file ?

See previous post first.

Well …. I loaded the English v6.1 … It looks great … but froze after about 10 minutes … I was just clicking the “backlight” icon at the time.

Operating the reset button only takes it to the white and green screen.

Turned off with the slider for a few minutes it reaches the Renaissance screen.

Turned off with the slider for a fifteen minutes it fully loads up … ran for 5 minutes before freezing while selecting media player.

What now?

[Upgrading, Modifying and Unlocking] DJAnt1320:
Hm.... Haven't had any problems with freeze-up, very often; that's only been a problem, or me, if it's been in my riding jacket and joggled around, a bit.

Lesse if i can answer these:

1... er, 3) Unknown. There could be something grounding out, but more than likely it's a RAM allocation error (Look in: 'Start > Programs > Tools.' There's an icon that says 'Freeup RAM.' I use this about 4 times a day - more, if I remember. It's helpful to keep things running smoothly.

When you're not running anything needed, first go to the Task Manager ('Start > Programs > Task Manager') and tap 'End Task (on the bottom Left) until all are cleared, then go to the 'Freeup RAM' and tap 'Ok,' when it bleeps at you.

4) Being that it's a modded ROM, I have no idea as to how Mitac would respond. Though I'm sure you could send it back to them and have them completely wipe it and make it an OEM box, again.

5) Money, from #4, or voltage? Unknown and all night.

6) The front button BASICALLY just cuts power to the front end (LCD and touch-screen interface). It actually doesn't have any bearing on the processor, directly. Kinda like just turning off your monitor, keyboard and mouse, all at once.

If you'd like, I can post pics of what the internals looks like, since I pretty much built the one that I've got.... Franken-'Puter. I have another one that works fine, just has an interface issue (the pins that connect the front-end are jacked up and so they won't connect to the main board, properly)... It actually still has WM5 on it!!

Hope this helps, some.

[Upgrading, Modifying and Unlocking] mio P550:
Thanks DJ,

With the same freezing problem occurring when it was standard – with the reloaded v5, and with v6.1 installed - I’m expecting it to be an hardware problem.

I tried the Freeup RAM as you suggested but it froze shortly afterwards.

Sorry for not being clear on the “charge” … I was referring to the cost.

It seems, like you, other people can turn theirs off with the front “power” button - return to it two days later – press the power button and it will instantly show the “Today” screen.

Mine has never done that. Two days later or even 30 minutes later there would be no response to the power button. It would need the bottom slider turning off for 15 minutes – back on – white and green screen then start up in Windows with the wrong time/month/year but all the files and programs intact.

Thanks for the log in tip and offer of the pictures but I won’t put you about unnecessarily.

Ray
[Upgrading, Modifying and Unlocking] DJAnt1320:
Hm... Maybe... Try 'Start > Settings > Power.' See if the power off mode is set for some retardedly low number...

Aother thing is that the battery, itself could be discharging, causing it to completely dump out? That's an odd one. Does it still do it when it's plugged in?

That would be a good test to see if it's the battery or a HW issue.

As soon as I read the “plugged in” idea I dashed off to try it, and then realized it had been plugged in in the car when it first froze.

Nevertheless, plugged it in - started up on the slider - it ran for 5minutes before freezing. :mad:

The power off time is set OK.

It’s a new battery although it performs no better than the original one did.

: Not to my knowledge. I think JVC posted, saying that 'Crash' got his kitchen set back up and was back in the O550 ROMming game... I guess he's back to working the En6.5 ROM.

Anyone finds anything out, please post it... I'll be happy to beta test it.
[Upgrading, Modifying and Unlocking] jvchawk:
Ray,

From the displayed symptoms, it could well be a HW problem.

Now, is your device still within the warranty period and therefore can be repaired for free? If not, is it really worth to spend perhaps 30% of its price (~180-200 USD) to repair? Besides that, MIO support very likely will expect the returned device to run the factory firmware. Do you still have that copy?

If there are sentimental reasons to keep it, then there's nothing I can say. Otherwise, in the second-hand market there are smartphone devices that cost about same price with more capabilities (Phone, GPS, ... see HTC Polaris, Diamond) where you can flash state-of-the-art WM6.5 for free. My Polaris flashed with "cooked" WM6.5 before Xmas 2009 for instance is so beautiful and has not yet crashed.

Good luck!
[Upgrading, Modifying and Unlocking] mio P550:
DJ,

Yes it was happening whilst running the original WM5

I only learned about, and carried out the reloading after I made my first post on here a few days ago.

jvc hawk

It is out of the warranty period sadly.

I understand what you’re saying about the cost of repair – the only upside is I was gifted the Mio so it will be the first amount I’ve spent.

I’m assuming the WM5 MioP550 - Osc260A R05_P09.nb0 firmware someone kindly sent me ( not from XDA) - which I did the first reload with – is same as the original???

If so I could put that back on before dispatch.

I’ve since loaded the English WM6.1

You make a good point about the alternatives – I can see the attraction of an HTC.

1. Which is the best to go for? I prefer something used so I won’t mind fiddling with it.

2. Are there any models to avoid?

3. Can you get a screen mount for using sat nav?

4. Can you use any sat nav system on a HTC - TT7 for example?

Thanks again for you replies.

Ray
[Upgrading, Modifying and Unlocking] jvchawk:
Ray,

1. WM5 MioP550 - Osc260A R05_P09.nb0 is Win CE 5.0 and is for instance the official version after the one I had which was CE 4.0 . I think if you flash the device with this firmware, MIO will accept.

2. HTC has a number of models running Windows Mobile and more recent models running Android. Models running Windows Mobile are many. CPUs range from 300 MHz (E.g.: Hermes), 400MHz (E.g.: Polaris/Cruise), 533MHz (E.g.:Diamond, HD) to 1GHz (HD2). Screen size ranges from 2,8" (E.g.: Hermes, Polaris/Cruise) to 3,8" (E.g.: Diamond 2, HD) or 4,7" (E.g.: HD2). This is a very short and non exhaustive list. If you go to the HTC site www.htc.com you'll see many more.

There's of course no best one. I have the old Polaris (or Cruise) with a small screen and I love it. My son has a more recent HD flashed with EnergyRom and he thinks iPhone would be better! So, it's up to you. If you want something with screen big enough for navigation, go for 3,8" screen (P550 has a 3,5" screen)

3. I know that several people complained about Diamond, a friend of mine was one of them. On the other hand, Moonscapex said it's the best smartphone he's never had...So, again up to you.

4. I bought on Ebay a Car Holder Kit for HTC Touch Cruise for a few dollars, it sticks well on the windscreen but it does not hold the phone as good as the MIO original holder.

5. Any Navigation software for Windows Mobile (TT7, iGO, Navigon, Sygic McGuider, ...) can run all right on these.

Good luck.

Crashoverhead WM6.1 English on my P550- power issue

Hello everybody

Finally I dared to upgrade my P550 to WM 6.1 English- successfully.

Now it seems to have an issue with the battery power- either really really fast power drain, or an issue with the power meter causing quick shutoff.

Anybody seen this before? any cure or understanding?

No matter if the battery is fully charged, once I use WIFI and Explorer, the P550 prompts 'low power' notification, and shuts off within no more then five minutes.

Thanks

[Upgrading, Modifying and Unlocking] DJAnt1320:
Hey, B&T; Welcome!

Try this: Turn the PPC off (use the slider, on the bottom). Plug it in to an outlet charger (any phone charger that has a mini-USB jack) and let it sit overnight. The next morning, turn it back on and let it fully fire up. WITH IT STILL PLUGGED IN, turn on the WiFi and browser, then unplug it.

You can kind of see, from there, how much change you've got, if any.

While that was what I did, I do have to say that I've got a similar problem which only surfaced

after

doing the 6.1 flash... I don't recall if it did it when I had the French, 6.5 ROM, or not.

From everything I've seen from mine and the stuff that I've read, this isn't an uncommon thing with flashed 6.1 PPCs. It seems that 6.1 runs a bit of a different spec for power management (You've gotta think, most of the 6.1 ROMs come 'recooked' from a different hardware spec and thus makes power management a little different.)

WM 6.1 Power issue

Thanks, DJAnt :)

I always assumed the p550 does not charge with the slider in off position, since the light indication is off in that state. Was I wrong?:confused:

Another idea: Is there any application that can help with this power scheme issue?

and most of all- will CrashOverHead WM6.5 solve this problem?

Thanks

B&T
[Upgrading, Modifying and Unlocking] DJAnt1320:
From my understanding, the slider being OFF, and the light being off, as well, only means that the power output side of the board is inoperable.. The power IN side, however is still active. Basically, the light being on just means that the entire system is getting power, not just the battery.

I'm not really sure if there is, or not a power management app for this.... Maybe; perhaps tommorrow I'll try to hunt one down, but let's not hold our breaths.

As far as the 6.5 ROM, There's already one out, for the 550.. Albeit in FRENCH, but it exists, none-the-less. I can't remember if this was a problem with that ROM, as well, or not. While 6.5 is more eficient, it may have the same kind of issue, I just don't remember if it did for the week that I was running it.

Hopefully the En6.5 hits up, soon. I really like the dual-Axis scrolling of some of the apps I've got (Opera 10, Kinoma FreePlay). It'd be really sweet to have that, again... AND be able to read it!
