P350 users, test my release! :P

[Upgrading, Modifying and Unlocking] DJAnt1320:
That's your release, man? Awesome job; looks GREAT!

Have you had any P550 test-run it? I'm curious to know how it stacks up against the 'CrashOverhead' version.

Glad to see that there's another option for people to flash with!

Inversely, however, there are about 5 WM6.1 ROMs, already, and without someone taking a week to 'LowLevel' Flash and test, then 'LowLevel' Flash and test, again, I think they're gonna wanna stick to t tried and true edition.
[Upgrading, Modifying and Unlocking] Ham3r:
yeah, it's my, why not?

hmm.. i don't have P550, so i can't make a P550 version. I don't know, how it's working on P550 (bluetooth and wifi is not included)..

ROM is created by my mioromtool, and constains only IPL and OS, (i don't test flashing via SD card with lowlevelformat, i don't want a bricked device, it's not my..)

Where i get a fully-functional SDHC driver?
[Upgrading, Modifying and Unlocking] azboo13:
which one?

Ham3r, which kitchen did you use to create your rom?
[Upgrading, Modifying and Unlocking] Ham3r:
My own, based on Oscar250ADVT_WWE_R05_P09 WM5 ROM and old & my own build tools.

SYS is from HTC Topaz, prepaired for QVGA and optimized (it's from my HTC Wizard ROM).

mio p350

I look rom for original Spanish p350 or dump of p350 , it is possible to put dump of p550 spanish to p350 ?
[Upgrading, Modifying and Unlocking] adan_eson:
Now, I have another working MIO p550. I want to extract the original Rom (in Spanish) and copy it in the one with the problem.

-Oscar´s Rom doesn´t fit my MIO because I haven´t access to the SD after Dumping it and I need WM5 because I work with a program that only runs on that version-.

Wich tools do I need to extract it?

If it works I can upload the file.

Thanks
[Upgrading, Modifying and Unlocking] DJAnt1320:
Well, there're a couple ways to do it... One is to do a user dump (service menu) and the other's an app that was SUPPOSED to come with the ansar ROM... I've found it, before , but can't place, off the top of my head, where it's at.
[Upgrading, Modifying and Unlocking] adan_eson:
Then,I can make a file with the service menu and then use that file with the another Pda?

BUT I DIDNT FOUND ANY DOWNLOAD LINK
[Upgrading, Modifying and Unlocking] DJAnt1320:
As far as the options listed, I would say - since I've used all of them - is the 6.1 CrashOverhead ROM.

The Ansar ROM doesn't feel like it's complete and mildly rushed, in closing.

NTM every available option is fully ****ional and usable.

That all being said, if you know french, than I strongly suggest CrashOverHead's FR6.5 ROM.... WM6.5 in French.

Look back a couple of pages, to where I posted the DL links, to these ROMS.
[Upgrading, Modifying and Unlocking] DJAnt1320:
*** QUICK NOTE***

Here's my server where the ROMS are housed: http://www.utistunts.com/DbA/ROMS/

You'll see the Fr6.5 and En6.1, as well as the appropriate DNW.exe file and USB driver folder.

The 6.5 is ALL in French as the 6.1 is the reman in English.

I had this ROM, for a while, and the language barrier was why I went back to 6.5, initially.

As far as which RomLoader, it's not a big deal: Just do a 'LowLevel' then proceed as though you were going to flash a new ROM.

[Upgrading, Modifying and Unlocking] adan_eson:
Here again!

I´ve dumped to a SD the O.S from a working P550 (DUMP TOOL MENU 1) creating a pim.vol file. Then I,ve dumped it (DUMP TOOL MENU 2) to a non-working one and ... it works! But I have a third P550 and when I try to dump the O.S to that one... only green screen.

Should I need to do a lowlevel format?

If I try that format, is the pim.vol file enough to restore the S.O. ?

The OSCAR_ file doesn´t work properly on both machines (after dumping it from the SD, it can´t read the SD)

Thank You.
[Upgrading, Modifying and Unlocking] DJAnt1320:
I usually recommend people to do a 'LowLevel' anytime they do a flash, regardless if it's "needed" or not.

I've had some ROMS need it done and others not, so it would be a hit-or-miss trying to determine which is which.

I'd say go ahead and do it and circumvent that step, altogether...

Either way, if the ROM's going to work, it will.

DNW

I am trying out the 6.5 English by ansar...thanks for all the hard work, it looks good..need to play around.

To those trying to install on Vista machines: the UBS connection did not work at least for me. It kept saying cable not connected. Because no USB driver was there and the one given in the USB driver folder cannot be installed as it was considered invalid by Vista.

So I downloaded new DNW (version 1) from Samsung website after a bit of googling...

unfortunately cannot post url for some reason...if you google for dnw and S3C2410 you get it.

the new version of DNW which also includes a .sys file which seems to install fine. With this install done, you can either use the old 0.5a given by ansar, or the new v1 given in the samsung website to do the downloading into the P550.

Just use download instead of transmit menu option in the new program.

I am not sure if general vista problem or just my machine, anyway this workaround works..

Good luck!

One thing that I have noticed about trying to connect to various OSs is that sometimes you have to connect the Mio, then hit the 'reset' button... That's been an effective way of doing a 'Force Connect.'

I've got checksum errors several times with different ROMS, but it never affected the instalation (as far as I see). If your yellow light doesn;t turn on, check your usb connector on the device, try to move the cable (back and forth but really very gently -you can damage the device). Unplug the battery for a night or so - these are regular advices that might help. The light might not work if you have a fully charged battery.

I flashed ansar's WM 6.5 ROM (CE OS 5.2.28005, build 28005.5.3.0 WWE) onto my Mio P550 yesterday.

I tried following the readme he included, but that proved to be impossible on Vista: I couldn't install the USB driver that was provided.

I got a bit irritated so I did a low level format from the blue boot menu. I wanted to get a factory reset WM 5. After the low level format my device wouldn't turn on again. I thought I'd bricked it, so I tried ansar's flash procedure again. And failed again.

I then downloaded an older ROM (v6.1) by CrashOverHead and followed his readme: I copied ansar's WM 6.5 image to my empty FAT formatted SD card, renamed it from "Mio_P550_WWE_WM6.5.28205.LZX.MobileVista6.50SeaDragon_PP5_by_ansar.nb0" to "winceimg.bin" and booted into the boot loader menu again. I selected "0=Image Upgrade Tools" and then "1=Image by SD". ansar's WM 6.5 ROM was detected and installed in a few minutes.

This was a lot easier than the whole "by USB" procedure. Of course, I didn't have any of my old data on the Mio anymore, but I didn't care because I was about to sell the device anyway. But now with WM 6.5, it looks like it's usable again! I can finally connect to my WPA2 protected WLAN, on WM 5 only WEP was supported. The device should also be able to get a GPS fix faster thanks to the Ephemeris file, although I haven't been able to verify this. And overall, the whole thing feels a lot more stable and responsive.

My only problem with ansar's ROM is the look / theme. I already selected the "Classic Blue" theme, but the Start menu still looks pretty horrible. Is it possible to revert it to the standard WM 6.5 look or are the modifications hardcoded in the ROM?
