[P3600 Software Upgrading] joncgde2:
OK first of all I've put this together hastily so forgive me for slight errors, but most of this should be fine.

To flash your P3600i, there are 3 things that should concern you: HardSPL, the Radio, and the ROM.

HardSPL: something that allows you to run unsigned code on your phone (e.g. ROMs), and also provides protection in case it screws up. This is the first thing you do. (This is probably a **** explanation, but functional at least?)

Radio: I guess more like a mini feature set, I know there was something similar when I had a Motorola phone which was called a flex. In this case it's not a whole new operating system, but perhaps easily thought of as small tweaks made to improve the system without necessitating a whole ROM flash. Why have a radio when a ROM could take care of everything? Well the advantage of a radio is that you can flash these without resetting everything. Everything (contacts, etc.) remain intact.

ROM: What you're really after, WM6.1 and the lovely cooked ROMs that should soon be available for flashing.

This will wipe everything on your phone

, so back your stuff up (contacts, settings, owner info, messages, etc.).

Flashing procedure:

IF YOU HAVE VISTA: You need to update your drivers. Go here for instructions. You can then proceed with the procedure as per normal.

The basic procedure is this. Flash HardSPL first, then update your Radio, then finally, your ROM.

Note: The HardSPL you use is a modified one especially for the P3600i. Get it here.

Note2: Here is a mirror for the latest Radio for the P3600i. From following the guides, you will know when to use it. Get it here. (N.B. Radio link updated to v1.56.70.11 - 2 Aug 2008)

Go to the trinityguides.info guide (link here) and go through the procedure - and yes, I know the link points to page 2 of the guide. :)

NOTE WHEN FLASHING HARDSPL, IT WON'T WORK THE FIRST TIME - YOU WILL GET AN ERROR (CODE 260) LOLOL.

THIS IS EXPECTED

.

This is what happens.

You go to flash HardSPL like the guide says. LOOK AT THE SCREEN ON YOUR PHONE, YOU MIGHT HAVE SECURITY PERMISSIONS AND NEED TO MANUALLY ALLOW THE PROGRAMS TO RUN.

It looks like it's about to flash and then errors. BUT your phone is on the 3-colour bootloader screen! How odd. Well KEEP YOUR PHONE ON THE BOOTLOADER SCREEN, and unplug it from your computer. Exit the HardSPL program, RUN IT AGAIN, and FLASH THE PHONE AGAIN WITH HARDSPL (obviously connect your phone and stuff back to your PC).

The point here is this: the first time it will fail, but at least manage to get the bootloader up. With this bootloader up, exit the flashing program, restart it, and then you should be able to run the flashing program and have it complete.

DOUBLE CHECK YOUR PHONE HAS THE OLIPRO HARDSPL INSTALLED after completion, by soft-resetting (hold the power and camera buttons at the same time AND use the stylus to press the putton at the bottom of the phone. You might not get it the first time, but with practice you'll get the hang of it).

Once you can see 3.20 Olipro (yes, 3.20) on the bootloader screen, you know you have HardSPL on fine, and can proceed to the trinityguides.info instructions on flashing your radio and ROM. ROMs can be found in the P3600i ROM Collection thread, here.

Hopefully this should answer a lot of questions people have :)
