I know this is not the best place to type in a question irrelevant to P550/350 roms but im wondering, are the PNA's essentially what PDAs where before they got intergrated with the mobile phone?

Can they get upgraded with cooked ROM's like the normal PDAs do? Will they be missing external buttons? (like the MIO has the power off and 3 more programmable buttons).

I would really appreciate an answer since i can find really cheap PNAs in the market ( as opposed to the eclipsed PDAs leaving me with a PDA+mobile=Mobile-Windows device which is EXPENSIVE).

Thanx,

PNA: Personal Navigation Assistant (GPS). Example: TomTom device

PDA: Personal Digital Assistant (With or w/o GPS, with or w/o phone). Example: Mio P550

If I interpreted correctly your question, can a cheap unknown brand PNA paid 30 USD on Ebay be flashed with a smart Rom to become a complete PDA with all the features as MP3 player, Divx player, agenda, weather, Wi-fi...

In my understanding, a Rom is something that is written for a precise device and works only with that particular hardware. A Rom that runs well on Mio P550 does not necessarily run on a HP PDA. You flash it on the HP and you will likely loose it if you manage to complete the operation.

Another point is that you can't find a lot of those genius of Chefs willingful to cook Roms for every device found in the market. Look at the MIO P530/P550 and the Airis T620 that have (nearly) the same hardware. There must be several thousands of those devices sold all over the world and guess how many known Chefs have cooked a Rom for it? Just one! (CrashOverHead).
[Upgrading, Modifying and Unlocking] BLiapis:
Good point JV. For a moment i forgot that roms are hardware-based like our P550 is for and Airis too.

On the other hand there should be win-mobile roms cooked for a few PNAs (just a guess though).
[Upgrading, Modifying and Unlocking] jvchawk:
CrashOverHead are you still there?

Did you manage to complete the cooking of WM6.5 FR for HTC Touch Elf/Elfin? I know Airis and Mio are not the same as HTC but we really envy the Elf community for the shoot of adrenaline you provided them with via your superb rom.

A small doubt: do you still receive mail from this forum?

Bonne année!

P550 cannot boot up

Hello,

Can anyone help. I've a P550, recently it cannot boot. Tried soft-reset and hard re-set, but it just sit at the Mio splach screen and won't go any further. Thanks.
[Upgrading, Modifying and Unlocking] :
What version of WinMo are you using?

You are going to lose all your data, unfortunatly, but your Mio can be fixed :o
[Upgrading, Modifying and Unlocking] jvchawk:
MoonScapex,

Nice to have you back! I thought you were so upset with CrashOverHead who (you think) had missed the "set" deadline of end 2009 for the final 6.5 EN ROM that you decided to just fade...away!

Jokes apart, I fear we'll have litlle chance to see one day this Rom as there are more and more new devices with more capable HW that spending time to cook for "obsolete" technology devices like MIO P550 or Airis t620 is less and less rewarding. I only hope I'm wrong because I love my P550 running WM6.5. It's so stable now. Unpredictable failures are now part of the past...

ccpyue,

In this failure we know for sure of 2 things:

1. The battery is OK

2. The screen is OK

- Like you've already done, I would try first to hard-reset. But this time I would try to let it in this off position over night. Then I try again the day after.

- If it still doesn't work then I only hope that you have a backup of your device somewhere on your PC like MoonScapex mentioned earlier. The only reason is that you'll have likely to low format the device and reflash your Rom. Doing that will set everything on your device to factory values.

But before doing anything like that, would you be able to do a test and make sure your device can go all right to the blue screen for Rom administration (Hold the joystick down, press reset hole with your stylus then release the stylus while continuing to keep pressed the joystick until a blue screen appears)? At least if this works, we know we might have a chance to save the device.

The version of Windows running on my P550 was CE 4.0.

P550 stop at Mio splash screen

Hello,

I've done all you've mentioned. For data, fortunately I have sync with my PC 2 days before my P550 dead. I can bear with losing all data in the device.

No matter how I reset it, it canNOT go to the "blue" screen; it can only go to the Mio splash screen. That's it. Please teach me how to do a low level format in order to save this device. Bear in mind that this device cannot be recoginzed by my PC by connecting it with the USB cable.

Thank you very much.
[Upgrading, Modifying and Unlocking] jvchawk:
If the device can't go blue screen then we won't be able to do either the low format or flash the Rom.

The connection to the PC via USB is less critical at this stage because you can manage from your PC (only) to copy the Rom file to the SD card and flash the device from the SD card.

I would insist in trying different positions of the joystick (push down, pull down). One thing to remember: keep the joystick in the pressed position, reset and pull out your stylus from the reset hole, continue to keep it pressed until the blue screen appears.

Let us know.

Increase/decrease backlight in WM6.5?

Hello,

On my P550 I've been using Resco Today trial version that expired today. It provides amongst others, a function to increase/decrease the backlight to save battery life.

I first thought it's a matter of values in registry (HCU/ControlPanel/BackLight) but I was wrong. Partially, because changing registry values works for the Timeout with AC and Battery (in seconds) but for the screen brightness, it doesn't work.

Do you have any idea on how to change the brightness level of the backlight?

Many thanks.

http://www.zshare.net/download/591709639d417dc1/Error 404 - File Not Found

I need a safe and functional USB & SD method.

Personal conclusion, if the WM 6.1 ROM http://dl.free.fr/jok65wZqA downloaded at NO ERROR, then it is a compatibility problem with P550. It is better to UPDATE BIOS before instal ROM or else. Please tell me how best

On the positive side can enter the BOOT MODE , SD or USB ( no driver).
[Upgrading, Modifying and Unlocking] :
I'm using 6.1 right now, but I have seen a lot of discussion about that on the French forums. I think they found a solution.
[Upgrading, Modifying and Unlocking] :
OK, first try to install the 6.5 ROM (in my signature). I will reupload a working 6.1 ROM today. The one in the website seems to be corrupt.

Tell me if 6.5 installs.
[Upgrading, Modifying and Unlocking] jvchawk:
Thanks Moonscapex. Actually I've been told that in Windows directory there's a Power.exe file that can do the trick. I tested and it works OK with the screen brightness settings. So I created a registry entry and put this function in Settings/System.
[Upgrading, Modifying and Unlocking] emil1:
Hello and thank moonscapex

, for your help, I tried to INSTALL WM6.5 , Exactly the same WM 6.1 , everything is OK BUT BLACK SCREEN. I used the BOOT METHOD SD.

not work to use USB boot mode procedure, does not find USB drivers on automatic search, P550 can not connect with pc (can not find USB drivers). Do you think is safer USB method?
[Upgrading, Modifying and Unlocking] :
If 6.5 doesnt work than I hope its only an SD CARD issue.

I have never done USB upgrade, but I think its safer.

I tried to instaled with 3 different SD cards, one for every 128 MB and two 1Gb, all formatted in FAT. with all cards going the same, nothing different. Can you recommend which card to use. Or to use the method USB, but someone help me with the drivers for USB. Thanks.

I can help someone with a solution, please more
[Upgrading, Modifying and Unlocking] jvchawk:
emil1,

1. If you can flash then the screen and the battery are working. We can at least exclude these 2 elements from the debug exercize.

2. Perhaps useless question, but have you tried after the installation to HARD RESET the device? If you did, what screens/messages did you see exactly in sequence from the beginning? Did you see the initial splash screen? Is there any moment where the screen lights up before turning all black?

3. Try to format the SD card to FAT16 and flash again. From my side, I never cared to low level format the device before flashing. I just upgrade the WM6.5 new image over whatever was on the machine.

Perhaps I'm getting old and start to forget things but I've flashed twice the device with 6.5 and I do not recall I've seen all those messages during the flash!

I've a serious doubt on the integrity of the winceimg.bin that has been used. MoonScapex, do you have any idea on how we can make sure that:

1. Emil1 receives the correct file

2. There's no data corruption while transferring the file from the PC to the SD card?

Just to change this a bit I am having the issue that i updated the rom on my p550 and now it wont turn on it just sits there i am using the rom version 2.1 that i got from crashoverheads posts and i followed the instructions in it and nothing it happening just wondering if anyone might be able to help me out here
[Upgrading, Modifying and Unlocking] DJAnt1320:
Lock down, er... I mean up.

While I'm not really sure where, when or how often THIS issue has been addressed, as I haven't been able to find anything like it, yet - only similar...

I have a pair of 550s, one which has a screen-ribbon issue, and the other works fine... Well. DID, anyway.

I loaned it to my younger brother, last week, and when I got it back, it wouldn't boot. It's basically locked up, but NOT at the 'Mio' screen like most people's that I've read about.

It boots past the initial 'Mio' splash, to the 'Windows Mobile' screen..... And just sits there. I let it sit for about 6hrs, today, seeing if it were just slower than all hell.

NSL. When I came back, it was STILL at that screen.

After an hour on the phone to California (all the way across the country, from me) interrogating my brother, it finally came out that he'd done some update that one of his "computer buddies" told him about...

Bastard flashed my 550 with a 320(?) Actually, from what he'd said, he'd copied over some crap into the %root%\Mio folder and it ran fine.... Then he did a hard-boot so that his computer would recognize it (a fool-proof way to get the compy to read it: plug it in and hit the reset button, on the bottom), and it hung.

This is (er... Was?) my handheld for my company and now it's useless (can we say "paperweight" boys and girls? How 'bout "skipping-stone?" I knew you could).

Can SOMEBODY help me out, with this? I don't care if I need to sterilize the thing and reinstall the OS/ Firmware/ ROM...

Help? Hints? Advice?

All the above would be fine, just please drop in some links for file sourcing.

Thanks, a ton, in advance.

[Upgrading, Modifying and Unlocking] DJAnt1320:
Hmm...

okay... Per 'jvcHawks' AWESOME tutorial (btw, it's the 'giveio' driver, in case anyone's curious), I did the USB image bit. :D

One problem, though.... It's been sitting at 99% for a while (almost 15) and I'm wondering if that's ill or ?

Earlier I came across someone's post about the same thing, but reboot my machine (rebuilding SQL database), and my history's wiped.

Anyone know anything about the infamous 99% error? :confused:

'Preesh.
[Upgrading, Modifying and Unlocking] DJAnt1320:
Completely disregard.... i got a 'One-Up' from God (CrashOverhead), delivered by his holiness, Moonscapex.

I joined the darkside and went to WM6.5, per Mooscapex's siggy...

Did a 'lowlevel' and then followed Crash's directions...

LOL... Since his instructions said the first boot may take a few minutes (and I don't speak french), I waited and waited for about 30mins, thinking the screen would change...

Turns out it'd been telling me to touch it to calibrate the screen.

D-OH!

It's AWESOME! Super hero like, even!

Only quip in it is that I with I could've found one of the fables English versions... none of the links that I've found seem to be live. Anybody knows of one that's valid, please let me know.... I still need to get my other 550 working, for my fiance'.

As well, if anyone needs pretty procedural instructions on how to do this update/ patch, I'll be happy to help, as I can... I feel like I should give something back, ya know?

MAJOR thanks to CrashOverhead and Moonscapex!!!
[Upgrading, Modifying and Unlocking] jvchawk:
DJAnt1320,

Happy to know you've recovered all right your P550! (Perhaps it's the moment to take French lessons? I'm joking!).

I understood the only English rom for P550 is WM6.1 and always from CrashOverHead. Moonscapex has a copy of it. The WM6.5 exists only in French and in Beta version. For the time being.
[Upgrading, Modifying and Unlocking] :
I'll reupload 6.1 English later today.
[Upgrading, Modifying and Unlocking] DJAnt1320:
LOL.... Yeah. I was teling my fiance the same thing (about the french lessons)!

It doesn't HAVE to be the hottest ish on the planet... 6.5 is great, but english would be better.

While there IS a chance that I won't be able to get my other550 working, any ideas to what can be done with it? Las I actually got the screen to register, it booted just fine to the 'desktop', into the OEM OS.

I'm ALMOST tempted to just get another one, instead of fixing it....

Almost.

Thanks, guys. Will check back, in a bit.

That reminds me... Are there any mapping/GPS apps/progs in 6.5? After I did the install, I noticed that I couldn't find anything.... Which is left to be seen...

As it's in French!

Speaking of it being in French: Is the keyboard (for setting up the password in Hotmail/ Live) in a different order than a conventional 'QWERTY' kb? VISUALLY it is, but I wasn't sure if that was just a character difference or what.
[Upgrading, Modifying and Unlocking] DJAnt1320:

[Upgrading, Modifying and Unlocking] DJAnt1320:
Lol. No big, really... I understand that things happen; whenever you get a chance.

Question, though: transferring music and images to the 550L If there a certain process/ location specific to WM6.5? I rememeber that it has to be 'converted' and know right where to copy it TO (as it only reads 4 of 148 mp3s, currently located, onboard), just not the process for 6-5.

Ironically, I'm slowly getting used to using the icons... Though I'd rather just read it...

After I get the En6.1 file(s) I will upload both it/ them and the Fr6.5 one to a server that is pretty safe and stable. Let me know if there're any others.

Additionally: Anyone know where I can get a replacement LCD/ touch film assembly? I noticed last night that my OTHER 550's ribbon connection (which connects to the main board) has some 'pins' that're mangled and so I need to replace the assembly, altogether.

Any help on that one?

Transferring music to the mio P550 running WM6.5

I found an interesting little thing with the 550 & WM6.5, today.

Apparently, ASynch doesn't like to transfer music... In order to do this I've had to open Windows Media Player (WMP), go through all the set up crap, and do it from there. The odd thing is that it random has an issue... With itself. Well, not quite. See, I had to plug in the 550, there-in starting ASynch, while WMP was open.

then I had to *STOP* Asynch and start the music synch in WMP.

No problems.

Oddly enough that I'm finding the the 550 has some odd bits about it reading music from the SD, for import.

Am I just REALLY mucking something up, here?

Does this long awaited ROM upload support WPA2 PSK and SDHC cards?

When do you think you can reupload this 6.1 ROM?

WM 6.1 but which one?

Thanks for re-uploading this.

Can you please specify which 6.1 version this is and if it supports WPA2 PSK with AES, large SDHC cards and iGO.

I just re read the whole thread and I got confused. It is not clear what we get with this ROM. Is this the one that still has a few French stuff, no office nothing else and also does not allow to install any WM6 software?

Please clarify.

Thanks for your work and patience.
[Upgrading, Modifying and Unlocking] :
Yes, it supports WPA2 AES, but no SDHC. IGO works on mine, but it depends on the version. This is 100% english, includes office and works with all software.

Hope this helps.
[Upgrading, Modifying and Unlocking] DJAnt1320:
This U/L is for WM6.1, in English...The French version is WM6.5. I have a 2GB memcard in my P550, and there isn't any issue with it; I don't believe it supports WPA AES... Just standard WEP, as far as I know. Don't have iGo loaded - though 6.5 could benefit from it.

No office? Hm. I don't remember reading that in any of the posts... Excel, PowerPoint and Word are in WM6.5Fr.

Not really sure about the (in)ability to installWM6 software, either. I just installed 'Fennec' (FireFox's mobile browser ---> http://www.mozilla.org/projects/fennec/1.0a3-wm/releasenotes/) and it was fine....

Bottom line?

Flash both of them and decide.
[Upgrading, Modifying and Unlocking] DJAnt1320:
Heheh... Yeah.. That's what I was sayin'!
[Upgrading, Modifying and Unlocking] :
Are you still running 6.5? I posted the 6.1 link.above.
[Upgrading, Modifying and Unlocking] DJAnt1320:
I *JUST* reflashed it.... Waiting on the reboot, as I type. Will give status and, later on, post the links to the TWO servers I'm going to put them on.

*EDIT: Uhm... Perhaps I screwed up, someplace. It's still in French.... Both the 6.5 and the 6.1 filenames are the same, correct? The 6.5 date was 7/11/09 and the 6.1 date was from 2/12/10, and the filesizes are the same?
[Upgrading, Modifying and Unlocking] DJAnt1320:
Yup.... Still in French; even after redownloading and flashing a SECOND time and going into settings and changing it to English (United States).

[Upgrading, Modifying and Unlocking] mjuti:
Thank you guys for the clarification.

There is a patch ( found on xda ) for WM5/6 for supporting SDHC cards, I just wanted to make sure if that patch could also be used on this ROM. I have been able to use 8GB SDHC cards on my mio with the wm5 original rom.

Which is the latest IGO that runs smooth on Mio p550?

I am considering upgrading to 6.1 if there is a possibility to go back to wm5 if I want to. I have had several HTC devices for ages I am familiar with up/downgrading but this seems to be a slightly different story.

Does anyone have the original wm5 wwe ROM?

Can I go back to wm5 if this wm6 ROM doesn t meet my expectations?

Thanks
[Upgrading, Modifying and Unlocking] mjuti:
See, that is what I meant. Has anybody ever succesfully downgraded from 6.1 or 6.5 back to wm5 on a Mio p550?

Maybe this image is also corrupted?

Let me know how it goes.
