Just in case: How do you flash back to WM5?

[boomersooner]

Hello all,

First of all I am new to the forum and a beginner with regards to pda phones and upgrading software etc.. I am switching from the blackjack phone to a treo 750 which I recieved today. I have read alot of good things about WM6 ( the unofficial version), which I downloaded and saved on my computer. I plan on giving it a try, I believe the instructions are pretty straightforward on how to flash to WM6, now the question is if something goes wrong or for some strange reason I don't like WM6 and would like to wait for the official version, how do I flash back to WM5. Take it easy on me, I'm a newbie.

Thanks in advance.

I saw the answer posted somewhere in the main WM6 thread. You follow the same directions, but you need the WM5 rom. I'm pretty sure I saw someone post the download link for the WM5 rom.

I forget who the OP was... so my apologies for not giving credit for these:

OR

Those are the WM5 roms from Cingular. You don't need both, but I posted both just in case one link stops working.

does anyone know where to find the latest at&t Treo Rom for the rebranded at&t Treo 750 TREO750-1.13ATT
The ones listed are for the cingular branded 750.. not that there is much difference except at&t startup and shutdown logos and the alpha tag displays correctly..

As I am sellling this and it has the AT&T ROM on it, where can I get the Vodaphone or a generic WM5 ROM if asked to flash it back please? And it is just a case of doing what I did to put WM6 on here?
Thanks.

Thanks for that. Knew I had seen it before but couldn't remember where!

Where can I find the ATT rom? I just got my phone last month and I MIGHT have to reflash back to WM5.

I am having a little trouble flashing back to WM5. I have downloaded the Cingular Rom and did what the instructions told me to do.

I loaded the CHeeDIAG (Misspelled?) file to SD Card and then press and hold the Button below the volume buttons then press the Reset Button, but this is where the problem starts. It should ask me to press the Power button to start, but nothing happens. All that happens is it shows a screen saying "Loading". I have waited for at least 30 minutes and nothing else happens. What I am doing wrong? Thanks for any advice.

Is there an AT&T version of the rom floating about? I have a 750 on trial and would love to try wm6 but would need to get it back to factory if I decide to return it.

I am having the same problem trying to flash back to WM5, I need to send my phone back to AT&T for a warranty exchange but I can't manage to get the WM5 firmware back on it

Anyone knows where I can get this? Spotted a dead pixel on my Treo and I need to flash it back to make an exchange. Tried the Vodafone ROM but had trouble unlocking the extended rom (had the infamous "inserkey failed" error).

I have a friend that wants his Cingualr Branded Treo 750 flashed back to WM5 as he is doing a warranty swap. I have downloaded the files listed on this thread, and am getting the same results ashrobo got, when I put the freshly formated (FAT32) memory card in with the CheeDIAG.nbh file in and reset into upgrade mode, I get the following;

0058002

Loading...

It never doeas anything else. If I try to flash it with the ROM image, It gets as far as the OS section then fails. Any ideas?

Disregard
I found the thread that said you don't need to run the diags first. He is now flashed back to WM5.
