ROM Upgrade

[ezee_ezee]

Hi,

I have a T-Mobile Pocket PC Phone 2003.
Rom version: 4.01.16 ENG
Rom date: 02/04/04
Radio version: 6.25.02
Protocol version: 324e4
Wallaby Bootloader: V5.22

I am in a GSM 1800Mhz region while the phone has only 900/1900Mhz. I have read various reports that with a Firmware upgrade I can make the phone Tri-Band capable meaning 900/1800/1900Mhz. There have also been reports that this is a hardware feature which will not be effected by software upgradation. But I wanna still try. Firstly the phone was Simlocked by T-Mobile which I managed to unlock with a code given by their SimUnlock dept. believe it or not.

The problems / issues I am facing with this phone are:

1. Downloaded the XDAROM.exe with adaptROM.exe Program A.exe etc in it but it always stops at the dreaded -
ERROR: GetDeviceData - An existing connection was forcibly closed by the remote host.

error getting devicedata

For the above I have tried all the suggestions on this forum like hard booting (battery off/on), Select GSM900 in Wallaby Mode then reset, Remove Sim Card then Reset, Switch off Radio (which I presume is GSM) in Wallaby then reset. All options lead to the same error.

2. Tried backing up the current ROM in Bootloader Mode which it does and asks me to press the Action key. But when I reboot the device or remove the SD Card and plug it into a PC it says Card not formatted. The SD card
works under normal conditions transferring data to and fro and storing data.

3. Read that I can copy the .NB1 (update file) onto a SD card and on rebooting it should ask if I want to Flash the device with this new data but it never asks and reboots completely.

4. Wallaby mode is also supposed to Flash the device via USB if I press the record key I tried but the computer and device never connect.

5. Device does not ActiveSync always on docking very often I may need to reboot the PC and or the Device for them to talk.

6. Tried XDAUnlock. exe which gave me 'error getting unlock code'.

Any ideas people? Any help would be greatly appreciated.

In no particular order:

(1) 1800 MHz is a hardware feature. At best, playing with the firmware will make the phone think it can operate at 1800MHz, but it really can't without hardware changes. But hey, you already know that.

(2) When you dump the ROM to an SD card, it is dumped as an image, which overwrites any FAT formatting on the card. This is why you're getting the "Card not formatted" message on the PC. You need special PC software (XDATools -- available on this website, or XDArit) to access the ROM image on the card with the PC.

(3) In order to upgrade the XDA with an SD card, the firmware needs to be placed on the SD card as an image (the same format as #2 above). If you just did a PC file copy you used the wrong method. XDATools also does this function.

(4) Why are you trying to use XDAUnlock.exe when you've already unlocked your phone with the code from T-Mobile?

Hi,

Thanks I did finally realise what every one took for granted in this site that the ROM dumps on the SD were written in a proprietory image format not FAT format.

Am trying the entire exercise coz have read at enough places on the site that the phone can be cracked to be tri-band which is what I need for it to roam India. We have only 900Mhz at select locations and the rest is 1800Mhz. Can only but be hopeful.

The chronology for the unlock bit was off on my mail.

Basically I cant perform any updates to the phone via the adaptROM method because I feel Wallaby 5.22 has protection built into it and shuts down the connection. If I try to Downgrade the Wallaby to V5.15 using the bootloaderfix included XDATools I get the error listed below.

'C:\bootload\pput.exe' is not recognized as an internal or external command,
operable program or batch file.
ERROR: ITReadProcessMemory - Unspecified error

Unable to find flash info offset, cannot disable bootloader writeprotect

If I use XDArit V1.02 route to write via SD I get Failed to open Device \\.\PhysicalDrive7
Anyone got the older version of XDArit ??

Help people.

Thanks,

Andrew

I'm not as familiar with Bootloader version issues. My (old) unit was Version 5.15. I just got a replacement for it after I busted the screen, and the new one is Version 5.22. Maybe I'll learn more about bootloaders...

But LumpiStefan says he hasn't had problems using the SD card method with 5.22. I haven't played with the new phone yet, since it came with WM03.

Wouldn't it be easier for you to spend $100 (or so) on an unlocked 900/1800 phone?
