Treo 750 Cingular/ATT - Upgrading, Modifying and Unlocking

Hi All,
I have 2 treo's one unlocked and the other is not. I have installed windows mobile 6.5 which is pretty cool but I don't know how to enter in my unlock code on the locked treo using windows mobile 6.5. with previous versions 6.1 it prompted me when I installed a TMOBILE sim card which 6.5 does not.
I want to just downgrade it to 5.0,6.0 or 6.1 but I can't find a way to do that. I thought I found a good version of 6.0 in the cheeimg.nbg using the minisd method; formatted sd card fat32, put just that file "cheeimg.nbg" on the sim and reset holding the PTT button - it goes into a screen that says loading... and goes no further. I found a different version of the windows mobile and tried the same this time it went to the loading then to the booloader screen (multicolored) and then nothing.
All the links for Windows Mobile software for this phone links are dead so I'm stuck.
Could anyone point me to a good download link for any version of WM5,6, or 6.1 and tell me how to downgrade? I'm not that good with all of this so a step by step would be greatly appreciated.
Thanks again for anyone who can help me.

SX56: Unlocked 2 from AT&T. 1 from T-mobile won't let me

Hi!
Well i'm new in this forum. Thanks to the ones who are viewing this.
This is what happened:
I brought 3 Siemens SX56 from the US. 2 locked to AT&T (windows 2002 installed), one locked to T-mobile (windows 2003 installed).
As the bootloader was originally 5.22 for the three of them, I did the typical unlock supplied by XDA DEVELOPERS (replacing the original flash with the XDADEV flash and running xdaunlock.exe)
That worked fine with both AT&T units which are already unlocked.
However the T-mobile one refuses to give me the unlock codes when i open xdaunlock.exe (error getting unlocked codes)
For what i've been reading, this is most likely because win2003 was installed in this one and i heard it's harder to unlock. But that's just what i heard.
Could anyone help me unlocking it?
I really appreciate!
Thanks!
Nicolas.

Failed to do magic
search this forum for steps on downgrading ur rom to 2002 or even better is to just load the XDA-Developer rom onto it and it'll unlock it. then after that switch back to your original rom
remember to use xda tools to backup ur original rom on ur computer first!

Thanks a lot for your response
I already did that. I downloaded the roms from the at&t sx56 and loaded from sd card. The reason i did this is because the xda developers rom wouldn't let me run the upgrade with ppc2003 on it (a usb connection error was displayed)
I installed the 2002 ppc software and after that, i upgraded directly via ActiveSync.
Still i could not get the unlock codes (same error: error getting unlock code).
That's why i need help. Thanks!
interesting havent heard that one before.. have you tried downgrading to another t-mobile 2002 rom and then after that installed xdadev rom? or maybe downgrade the bootloader?
hi
i have same problem as nikoleman
i have a T-mobile pocket pc (i think it is WM2003 beta)
Pw10b1
rom version:4.00.16 ENG T-Mobile
with wallably 5.22 bootloader
i downgrade the bootloader to 5.15 and
the rom to 3.17.03 ENG cooked in kitchen
now infrared is not working and still get error getting unlock code
any help plz
yep
in fact that's the only way it would let me do it.
I backuped rom from the at&t ones and writed it to the t mobile. Then upgraded to XDA DEV special edition and it still throws me the "error getting unlock code" error.
Do you know why might this be?

HELP! T Mobile Dash Radio Version problem can not find network

I have a second t-mobile dash, it used to be a brick. Someone messed it up.
Luckly found a way to manully put it in bootloader 3 color mode (holding the camera button for 3-4 seconds and hit the power button), then downloaded the latesest WM6 rom from T-Mobile 1.22.531.4. Flushed succefully, rebooted and the PC part of the phone now works perfectly.
Big problem is that it can not find the T-mobile phone network. That part just keep searching... No network. Testing by plugging in a cingular sim card. Prompt me for sim unlock code. So I guess the sim slot is at least working and it's reading the sim card. Used other perople's sim card, still not working(of course the sim card still work, plugging into my old samsung phone).
The radio version is now 4.1.13.34_02.79.90 . It's way different from my other dash...I am suspecting it to be the cause. WHAT RADIO VERSION HAVE YOU GUYS GOT?
Any idea how to fix it? try with changing the radio version may be?
Thanks
Can a few people just tell me what radio version are you on?
I was wondering, would a stolen phone be locked by the carrier so that the phone can't detect network?
This item is bought through ebay so i don't know what the previous guy was up to..
Thanks
Leo
Radio version change
Come on guys, anyone?
How about if anyone would like to point me to the right direction in how to change the radio version on the t mobile dash... is it a hardware thing or a software thing.
Thanks
Leo
there is a radio updtae in the ftp :
ftp://xda:[email protected]/smartphones/Excalibur
but i don't know if this upgrade is good or not
no, this radio upgrade is no good. do not even bother..
I suggest that you flash original T-Mobile firmware to this handset. Be that WM5 or WM6 and see how you go.
my Excalibur is HTC S620, radio version: 2.63
Firmware or ROM?
Thanks guys for your reply.
SecureGSM : Do you mean the ROM for the whole WM6 software (which I have already flushed.. twice). Or a firmware like a computer bios? If there is a firmware please point me to the right direction I'll definately want to put it in.
Thanks
Leo
Hi,
I was referring to the original WM5 T-Mobile ROM. You might have a better chance with it.
Radio version 4.1.13.34_02.79.90 is provided in the WM6 upgrade from T-mobile.

Help with 8125 Upgrade to Newer Versions of WM6

I have an 8125 and I currently have WM6 5.2.318 (Build 15342.4.0.01) installed with SPL/FPL 3.08 and I have not been able to get the last 3 versions of WM6 that anyone has put out to work. Two of the updates get to the bootloader and then I get an error back from the pc that the USB isnt recieving information from the PDA and then the Bootloader sticks till I reset my 8125 or take the battery out, the others get through the verification process on the PC and then after I have agreed to everything it closes my Activesync Connection and never loads the BootLoader on my phone and eventually errors out on the PC for NO communication. What is Going on? HELPPPPPPP.
Do you know if you have a G3 or a G4? Did you Cid Unlock your phone? without knowing more. All i can say is read and read some more on these forums.
Thanks for the Reply
I have a G3 and yes I did do the CID unlock. Any help would be appreciated.

Trying to install kavanna 6.1

the thread with the how to seems broken at the moment no pictures, but trying to install the kavanna 6.1 rom after pressing the centre button I get the white screen then my handset disconnects from PC and am unable to proceed with the update get connection error 260 am using win vista ultimate if that makes any difference with latest version of the mobile device centre.
there's another link with a .pdf file with the instructions you can also use as well in that thread.
Thanks managed to sort it but now my sim is invalid I have 3uk sim but the phone is not recognising it although I have tried a t-mob uk sim and it is ok is it possible to get this phone to work with 3 uk
you'd have to get your excalibur sim unlocked.
you can either go to imei-check or go to the sim unlock thread by jockyw2001 and he will sim unlock it for a nominal fee
The 3 sim is the only one that does not work, t-mob,o2 vodafone all ok just the 3 sim in coming up as not valid.

Help, Tmobile vario III unlocking

Hi,
Guys i really need your help.
I' am in India and i got a T mobile vario III from a local place. It was unlocked and was running on WM 6.0. I wanted to upgrade it to WM 6.1 and its similar to TyTynII in India so i googled for a serial number and hard flashed the rom with the TyTynII WM 6.1 Rom. I have a UK mobile and it every time i insert a sim card from Airtel, hutch or spice asks me to insert sim card. The serial number of this device is HT816GB03362 . This is the phone's official link: http://www.tm-phonedownloads.com/sd_vario3.html.
I had problems with sound which was fixed by flashing a base Rom of kaiser and then flashing with tmobile WM 6.0 however the sim card doesnt get detected. I took it to HTC local service center and they were not able to figure it out.
I tried all the sim unlocks available in HTC but i dont know which radio is compatible with these providers.
I have a couple of websites which offer tmobile unlocking eg: http://www.gsmliberty.net/shop/tmobile-vario-iii-instant-remote-unlock-p-1520.html i dont know if it will work
Changes: Everything is default and sim card is not getting detected
The screen comes with "Smart mobility" whenever i turn on the device instead of "Tmobile"
Every other function works and it has hardspl 1.0 oilmod installed
I also tried to flash with the original tmobile 6.1 ROM on this device but the sound doesnt work
If anyone can point me to the right direction or let me know how to get this fixed i will be greatful
