Me han estado preguntando como le hice para actualizar el ROM de mi treo 750, asi que aqui les dejo los archivos, pero debe de quedar claro que NO ME HAGO RESPONSABLE de Cualquier falla, error, perdida, descompostura, etc, que pueda suceder en tu TREO.

A mi me gusta experimentar y por eso lo hago, si algo hubiera salido mal, pues no me hubiera quedado otra más que “apechugar” y ver que hago, si eso les pasa, eso tendrán que hacer.

Por otro lado, estoy casi 100% que el ROM es para equipos AT&T, ya que trae los iconos de esa empresa, pero no creo que afecte el funcionamiento si estas con alguna otra.

Recuerden que esto es un poco Peligroso y de preferencia debes de Tener EXPERIENCIA para hacer este tipo de cosas.

Los Archivos (son 3) los puedes bajar aqui:

http://rapidshare.com/files/121533735/ROMTreo750_6_1.zip.html

http://www.mediafire.com/?4gxsdxh1tmm

Los pasos que yo hice fueron:

0) Sincroniza tu Treo con tu PC (como regularmente lo haces)

1) Desbloquear el Treo 750: El Treo se desbloquea con el Archivo “CheetahUnlocker.exe”, pero como me marco error despues del segundo paso, lo que hice fué copiar al TREO el archivo que se encuentra en:

C:\TempChe\athena_unlock.exe

Y ejecutarlo directamente desde el Treo

1.5) Desconectar el TREO de la PC y verificar que tenga MAS del 75% de Carga

2) CAMBIAR EL RADIO: Debes Renombrar el Archivo CHEEIMG-RADIO.nbh por CHEEIMG.nbh y copiarlo a una tarjeta MiniSD Limpia (la cual debe de estar formateada en FAT32 y a 512 bytes) y “Flashear” (no se como se dice en español) tu Treo con ese Radio.

Para “Flashear” es necesario Apretar el Boton del COSTADO Izquierdo (el de hasta abajo) y SIN SOLTAR EL BOTON darle al boton de RESET con el Stylus:

Solito empieza a Actualizarse.

3) Realizar un “HARD RESET”

4) CAMBIAR EL ROM: Borra el Archivo del Paso 2 y Ahora debes de renombrar el Archivo CHEEIMG-WM6_1.nbh por CHEEIMG.nbh y realizar exactamente los pasos 2 y 3

A soft reset tells to your device to stop what it is doing and to restart.
All records and programs stored in device will be retained after a soft reset.
After resetting, the usual start screen will appear.
Use a soft reset when your device seems to have crashed or hanged.
This type of reset is the first to try, before any others, to solve the above problems.
This kind of reset is, usually, well known by the user and really easy to perform.

Find the reset button on the handheld device.
It is located in a hole on the back of the device.
Get your stylus or the reset tool located in your stylus,
or any other object with a small end (a paperclip if any).
and push with it into the reset button inside the hole.

Exception: Hp h19xx – Dell AXIM the reset button is on the left-hand side
of the unit and this happens now for many pda/phone also
. For h1940 there is a reset nib in the stylus that can be
found by unscrewing its top.
Hp 36xx/37xx series can perform an hard reset if you press
the reset button for more than 3 seconds. Reset button is at
bottom right of the device
Quite unusual for HTC Touch HD the position of the Soft reset
button that is under the battery cove between the Sim and the
Card slotsr

Hard Reset (or Full Reset)

Performing a hard reset, all settings, records and programs stored in the Pda
(except the ones stored in Rom) will be erased.
After a Hard Reset formats, preferences, and other settings will be  restored
to the factory default settings.
You can restore any previous data if you got a Backup of your device before
the hard reset otherwise you will need to reinstall any third-party applications.
If you are hard resetting your device owing to some hard problem i suggest
to restores installed applications without using the backup if you are not sure
that backup data do not include the problem you wish to solve also.
In few words a hard reset allows you to start everything over from scratch.

WARNING: for WM 5.0 users (wrongly called also as  WM 2005)
The new operative system Windows Mobile 5.0 totally modified the use and the construction of the
internal memory of the PDA. For all the models that use this new O.S. the Ram is used only as the
operative memory while the users’ programs before loaded into the same kind of memory are now
stored in Rom (or FRom, FlashRom etc) that is working now as an HD and is no longer subject to
the lost of data following a full discharge of battery.
What said above causes a possible different execution of the usual HardReset operation.
We can note that, while the soft reset is still unchanged, for the classic Hard Reset, that resumes
the original default setting, has been added new processes with different name and result quite
different from the hard reset as usually known.
We may say something like the Warm reset of Palm already used.
So for any new pda will be added the new procedure if any (the one that is different from the
classic Hard Reset ) and it will be shown by a different colour.

ATTENTION: The soft reset requires only to push a button and the only
difference is the place where this button is located.

locations.

A warm reset bypasses any system extensions (such as HackMaster hacks, operating system patches, and so on)
that are loaded on the device. A warm reset often bypass the “boot loop” error, allowing you to remove applications,
previously installed, causing problems. All stored data in the device remain unchanged with a warm reset.
To perform a warm reset hold down the top scroll button and press the reset button inside the hole on the back of
your unit. When in the Palm display you see the general  preferences screen, release the top scroll button.
After a warm reset, you may need to perform a soft reset to get the device working as normal.
Performing a hard reset you start everything over from scratch. Be sure to back up your files first.
Perform a hard reset only if a soft or warm reset does not solve your problem.
To perform a hard reset hold down the power button (Wireless Mode button on the Treo 600) and press the reset
button on the back panel. When the Palm screen appears, release the power button.
You will get a message informing that you are about to erase all your data. To continue, press the top scroll button.
To cancel, press any other button. In this case you will get a soft reset only.
After a hard reset calibrate the digitizer and verify time & date.

9. Open File Explorer and click the drop down arrow, in which you will now see ExtendROM. Open it and delete the 2 files in the partition folder.
10. Download, extract, and run CheetahUnlocker on your computer. For this part make sure you have an ActiveSync (XP) or WMDC (Vista) connection to your phone. Click Flash SPL and go through the steps for CheetahUnlocker to Flash SPL. Don’t worry about any of the other items in the menu.

11. Upon completion, the Treo 750 will continue to boot-up and go through the initial start-up steps and wizard. Once completed, your phone will now be unlocked, unbranded, and updated to Windows Mobile 6.1.

I made this thread to help people unbrand, unlock, and update their Treo 750s without having to waste hours looking for solutions and how-to something. Basically, made it easier for the noobies and everyone else to find everything in one thread.

Lo primero es tener a mano las herramientas para el desbloqueo, sin costo por supuesto:

• MS ActiveSync 4.5
• CheetahUnlocker
• Magic_Unlocker

Para los impacientes, un resúmen del desbloqueo considera lo siguiente:

• Instalación de MS ActiveSync y sincronización del Treo 750
• Hard Reset del Treo 750
• Resincronización con MS ActiveSync
• Ejecución de CheetahUnlocker, esto incluye tres pasos, pero solo se ejecutan los dos primeros
• Ejecución de Magic Unlocker

El procedimiento en detalle es como sigue:

Instalación de MS ActiveSync y sincronización
Para comenzar es imprescindible tener sincronizado el Treo 750 con el MS ActiveSync, en rigor es suficiente que el ActiveSync conozca al Treo como un invitado. Una vez hecho esto, es importante respaldar toda la información del Treo en el PC. No lo había comentado, pero este procedimeinto es válido para Windows XP.

Hard Reset del Treo 750
El respaldo anterior es algo que no se debe obviar, dado que mi experiencia me indica que para realizar el desbloqueo es importante partir con un Treo “factory default”, es decir es básico realizar un “Hard Reset” del Treo antes de comenzar. Este procedimiento se realiza presionando con el lápiz el “botón de reset”, ubicado bajo la tapa a un costado de la tarjeta mini SD y de forma simultánea el botón rojo de encendido. Luego se debe presionar el pad en la dirección hacia arriba, tal como lo indica la pantalla del Treo 750. Esto borrará toda la información del teléfono, dejándolo en estado “factory default”.

Resincronización con MS ActiveSync
El paso siguiente es resincronizar el Treo 750 con MS ActiveSync, y que el teléfono vuelva a ser reconocido por este programa.

Ejecución de CheetahUnlocker
Una vez que el Treo 750 se ha resincronizado con MS ActiveSync, se está en condiciones de usar CheetahUnlocker. Antes de ejecutar el CheetahUnlocker, el Treo debe estar conectado al PC y a MS ActiveSync. Al ejecutar este programa, aparece una leyenda deslindando responsabilidades por parte del grupo que lo hizo, se debe aceptar esto. Luego se procede con el paso 1, Flash SPL. Esta parte toma unos diez minutos.

Al comienzo aparece una serie de pantallas con la figura de un HTC Hermes, otro teléfono, pero no te asustes este procedimeinto funciona bien con el Treo 750. Después de una serie de pantallas, se debe poner atención al teléfono, el procedimiento envía dos programas al Treo, que deben ser ejecutados, para ello se debe aceptar la ejecución en el teléfono presionando la tecla respectiva en el Treo. Luego en el PC aparecerá una barra de progreso en 0%. A estas alturas el Treo ya deberá mostrar una pantalla tricolor con franjas horizontales, es el modo bootloader. Si después de algunos minutos no aparece esta pantalla tricolor, y el Treo muestra una pantalla casi apagada con algunos signos de intermitencia, se debe mantener la calma, algo pasó y en el PC se verá un mensaje de error. En este caso, se debe repetir el proceso anterior.

Si todo va bien, luego de la pantalla del bootloader en el Treo, aparecerá una barra de progreso, que se irá actualizando de forma sincronizada con la del PC. Una vez que se llegue al 100%, esta parte del proceso habrá terminado, en el PC habrá un mensaje de felicitación y el Treo se reinciará automáticamente.

Se debe esperar a que el Treo se reinicie completamente y se vuelva a completar la conexión con el MS ActiveSync. Después de ello, se debe seleccionar el paso 2, Unlock Radio. Al igual que el primer paso, este también tomará unos diez minutos.

Tal como en el paso 1, en éste se envía un par de programas al Treo, por lo que se debe estar atento a la pantalla del teléfono y aceptar la ejecución de los mismos. Luego de algunas pantallas que se deben seguir, apareceré la barra de progreso en el PC, mientras el Treo debería mostrar la pantalla tricolor del bootloader. Si no hay patalla de bootloader, después de algunos minutos se mostrará un error en el PC y se deberá repetir la ejecución. Si por el contrario, todo va bien, las barras de progreso alcanzarán el 100%, tanto en el PC como en el Treo y se habrá terminado la mitad del procedimiento de desbloqueo.

A continuación nuevamente se deberá esperar el reinicio completo del Treo y su reconexión con MS ActiveSync. Luego de esto se debe dar un Ok en el PC, para continuar con el paso 3. Sin embargo, aquí se producirá un error y es el momento de cerrar el Cheetah Unlocker y terminar su ejecución.

Ejecución de Magic Unlocker
La etapa siguiente y final, consiste en ejecutar el Magic Unlocker, este es un programa que se ejecuta en el Treo y se debe copiar al directorio Mis Documentos, o al que se prefiera en el teléfono, usando el Explore del MS ActiveSync. Una vez que el Magic Unlocker ya está en el Treo, se debe ejecutar y uego seleccionar dos veces Unlock. A continuación aparecerá una pantalla con las opciones SIM Unlock y CID Unlock, con sus respectivas cajitas de selección, además de la opción Unlock. En mi opinión es preferible seleccionar una opción cada vez y ejecutar el procedimiento por separado dos veces. Al final, el Treo solicitará su reinicio.

Luego de lo anterior, el Treo 750 ya está desbloqueado y se está en condiciones de usarlo con la SIM de nuestra preferencia.

Hard Reset del Treo 750
El respaldo anterior es algo que no se debe obviar, dado que mi experiencia me indica que para realizar el desbloqueo es importante partir con un Treo “factory default”, es decir es básico realizar un “Hard Reset” del Treo antes de comenzar. Este procedimiento se realiza presionando con el lápiz el “botón de reset”, ubicado bajo la tapa a un costado de la tarjeta mini SD y de forma simultánea el botón rojo de encendido. Luego se debe presionar el pad en la dirección hacia arriba, tal como lo indica la pantalla del Treo 750. Esto borrará toda la información del teléfono, dejándolo en estado “factory default”.
