I think Joe figured out why Mike's method worked... because it's not actually creating the file unless you use the browse button ("..." button). This may be the key to your problems if you're having trouble creating the oldsim.raw file.

"Definitely worked fantastic! I used it to unlock a MOT MPX200 from ATT
Wireless to T-Mobile--took a little while to get it to work and one thing
was messed up. When you save the oldsim.raw you have to choose where it's
going from the box with the "..." so that way it actually makes the
progress of creating the file, I just chose to put it as c:\oldsim.raw and
it didn't work until I used the "..." button.

But it was awesome. Leaving credit where credit is due.

thanks.

-Joe"


Thanks for the tip on using the browse button to create the oldsim.raw file, however I have a different issue. After creating the oldsim.raw file (on two different machines) in command prompt I get the error :
"cannot read input file :c:\oldsim.raw" therefore I am unable to create the newsim.raw file. Any ideas or suggestions?

For anyones future reference, here are some solutions:

The program FixIMEI.exe looks for oldsim.raw in C:\Documents and Settings\User Name\oldsim.raw - merely copy the oldsim.raw and haha.raw files to that location.

Also, when in the DOS prompt, during the file conversions eliminate the "c:\" from the conversion commands -

Example: Do NOT type "c:\oldsim.raw c:\newsim.raw"
DO type "oldsim.raw newsim.raw"

The same syntax applies to the .bin file conversion i.e. eliminate the "c:\" from the commands.

Hope this makes it easier for anyone else in the future. Thanks again Rasoul.

These steps you mention are unnecessary ( for me at least) and I've unlocked over 50 mpx200 handsets using this app. You would only omit the c:\ form the command in the dos prompt if you had saved the files somewhere other than the root.

fiximei does not 'look' in any specific directory - if you omit the path by leaving out the c:\ it looks in the CURRENT directory you are running it from, as per most dos apps. If you have saved the file in the root you need to tell it the file is in the root by entering the path. Kinda obvious really, and the instructions as written DO work perfectly. You're just confusing the matter with your own interpretation which doesn't help.

Any chance of this possibly working with a mpx220?

Crazier things have happened... but if you're having trouble...

I got an e-mail from someone trying with no luck on unlocking his mpx200 with my site. After endless aggrivation, and 3 days of e-mails, he e-mails me and said he got it... so I asked him how he got it to work, here's what he said:

"Hi. I did it on my other computer. I do not know why it didnt work on my other
computer with exactly the same process."

Strange... :)

But, I guess if you're STILL having problems, try another computer. ;)


Eerything seemed to work fine until i tried the Motorola mobile upgrade on it. I get this error message;

"Bad News! Upgrading Motorola MPx200 has failed. Please re-upgrade the Mobile or Contact the Service Provider."

has anyone encountered this problem??

Thanks for all of the helpful suggestions here, and to rasoul for having
put in the time required to help figure this trick out!

For my part, I still haven't successfully executed MPX200_Backup.

The smartfon.inf driver, apparently for XP, does install under my
Win2K system.

Starting the phone in modem mode does cause it to show up on the
list of active modems. It can be sent the standard query string, and
it does respond to that query.

I have run MPX_200_Backup a number of times now. I did set 256KB,
and RAW. I did, as suggested, create an empty file OLDSIM.RAW, and
I did use the browse function to select that file. And I did capitalize the
file extension.

The program runs, and it does cause the backlight on the phone display
to cycle as it does that. At the end, though, it pops up not the expected
one, but two incomprehensible dialog boxes in succession. And the zero
file length of OLDSIM.RAW does not change. Gnar.

I have tried a few more things. I went in and attempted to send the
modem the query string again after MPX_200_Backup finishes running
and has been closed. In that case, the modem does not reply. Battery
must be pulled to reset the unit.

I altered the speed parameters under the modem driver settings, and
disabled the UART option. This did not change the behavior at all.

I've run the program with and without a SIM card installed.

I did find a note about disabling ActiveSync on the phone, but I am
unfamiliar with Windows for phones. I haven't had any luck in forcing
it to bring up a config screen: as soon as the unit finishes booting up,
it goes to an inescapable screen saying, "Insert SIM -- Emergency
Calls Only".

Open to suggestions here, if anyone has any! Thanks.

Ah, forgot one thing, of course.

I'm attempting the unlock from a laptop. Found a note to the effect that
the MPx200 likes about 500mA of current, and that some USB ports may
not provide this much.

No idea what this system actually puts out. But the phone is plugged in
directly. There is no passive hub wasting power.

Okay, I repeated the identical sequence on someone's XP desktop
machine, and it worked perfectly on the first go.

There are two things which suggest themselves as having caused
the operation to fail on a Win2k laptop:

(1) the person who wrote the application may have used an XP
specific API call. Tsk. Poor software engineering practice, unless
it was for something the app really needed (unlikely). But since
I have benefited by this anonymous Chinese programmer's work,
I am not going to complain too loudly.

(2) the USB port on a laptop may just not put out enough current
to keep the phone happy while this operation is going on. I would
guess that the phone interprets low current as risky in the context
of allowing reflash operations.

Anyway, if anyone else has trouble, I recommend scouting around
and trying different systems.

Brilliant! Worked a dream first time! Now I can tell Orange to stick their itemised billing charge where the sun don't shine. Speaking of which, has anyone else noticed their bill increasing since the itemised billing charge was introduced. (only applicable if you didn't agree to pay them for itemised billing). I asked them to Sim unlock my phone a few times in the past and they told me they couldn't (read wouldn't)

I know the Mpx 200 is soooooo 20th century now, but I like it, its small and does what I want it to

Hey, sorry haven't been on here much to comment, but thanks fluffcat1 for the awesome DOS/directory tips and everyone else contributing tips.

In the instructions I put a definite path of C:\ to make it more universal and not have to worry about "am i in the right path?" - you could just create the oldsim.raw (and consequently newsim.raw) right on the c:\ directory. (that's why in step 2.b.3 I have them specify C:\oldsim.raw, because just oldsim.raw would put it in current directory, and it makes it easier to get lost on the DOS part, depending on the perspective)
Notice the first step is to cd (change directory) into the folder the tool is located in... then after that, point to c:\ for oldsim.raw and newsim.raw. Either method works though, you just need to be careful and either use all full paths or all relative paths. :)

Again, thanks for the pointers.

Another issue I'm not sure about... user sent me this e-mail.

..."I got stuck in the very first step. You said turn off the phone and press the left arrow button and then connect it to the computer. Once you hear the ding noise let go of the left arrow key. This did not pull up the found new hardware for me. I tried it a few times but without any luck. Could it be that since I have the motoroloa mobile phone tools installed on my machine, that it is not asking for a driver? In that case what should I be doing?"

Anyone have any ideas?

I was e-mailed this question:
"I did everything to the very last step but it says 'bad news failed updating'. I followed everything exactly as your guide said. What could be the problem?"

I would start troubleshooting with the newsim.raw file...
What is the file size? Is it zero kb? If the file is empty it could be that either the template file (haha.raw) is also empty or oldsim.raw is empty.

Got the same message. Everything worked fine until this last step. Tried it again, reinstalling the modem driver and upgrade wizard, but the result was the same. Also have tried to flash other ROMs onto the phone, but again the same message. It seem that the flashing won't work. Any solutions??

My MPx200 is locked to Orange UK, and am using Windows XP on my laptop.

Hi jl13,

Have you tried it using a PC instead of your laptop, I think there may be a power supply issue when using a laptop?

Couldn't believe it, but it did work when I tried another laptop (did not find a desktop).

Thank you very much for your help!!

This MPx200 looks like a very nice phone indeed. :D

then again, in that sense, i used to not be able to detect it on any of my usb ports except one, that one doesnt work now after a reboot, but i used a usb hub/card reader thingie, and when the phone is connected to that, it worked fine.
