[Mogul, XV6800 ROM Development] rambo6:
I am an experienced flasher and I had a very tough time getting this ROM flashed right. Here is what I found. I hope this is helpful to someone. Here's what I did and here's what I found:

First I hit the green phone button and then dialed ##786# (I'm a sprint customer). A screen appears. You need to copy the MSD# (should be the same as your phone number) and the MSID# which may be different than your phone number.

The correct procedure is to call Sprint and get your A-Key. (I didn't do this until after I'd flashed. Best to get info before you start. They will ask you a bunch of questions to verify It's really you. They also asked for my driver's license number. They're on to everyone reflashing. Tell them you're trying new software. WRITE THE NUMBER DOWN.)

1) downloaded the Hard SPL 2.40., then the ROM, then the RADIO.

2) Connected via Active Sync.

3) Flashed the Hard SPL file.

4) Flashed the ROM. Here it got stuck at the Yellow Sprint Screen. I could not get passed it. So I held down the power and camera buttons while simultaneously doing a soft reset. This starts the 4 color screen bootloader.

5) Then flahsed the new Radio file.

After flashing the new Radio, my phone would not boot past the alignment screen. I reset the phone several times. The phone was unusable.

So I put the phone back in bootloader by holding the camera, power, and soft resetting at the same time. I got the 4 color bar screen. HERE I NOTICED THAT I HAD NOT FLASHED HARD SPL 2.40, IT WAS ACTUALLY 1.20. THE FILE I HAD DOWNLOADED WAS NOT HARD SPL-2.40 more on this later.

With the phone in the Bootloader, I flashed the Official Sprint 2.17 ROM. That ROM includes the Radio and the ROM. This brought my device back to life.

I next made sure I downloaded the proper HARD SPL-2.40 from the web. It wasn't on XDA-Developers site. I think it was on ppcgeeks.com

After flashing the correct Hard SPL-2.40 file and following the instructions precisely, I flashed the ROM then the Radio ROM. You can make sure that you've got Hard SPL-2.40 Olipro by putting the phone in bootloader - holding power, camera, soft reset at the same time.

After I was sure I had Hard SPL-2.40 Olipro, I flashed the ROM and the RADIO ROM.

The device booted normally but it woundn't connect to the Sprint network.

Hit the green phone hardware key.

Enter ##778#" There will be three choices. Choose "Edit" This is where you're going to need the A-Key.

Then enter the A-Key password given you by sprint.

Next you will have to enter the MSN and MSID. Enter each separately. AFTER YOU HAVE ENTERED EACH, DO NOT LEAVE THE ENTRY SCREEN. You need to hit the right button on the bottom right of the screen (I think it's and "OK" button). Then choose something like accept (I writing this from memory).

You phone should reboot and be ready to go. NOTE IT TAKES A FEW MINUTES TO CONNECT TO THE NETWORK. GIVE IT FIVE OR TEN MINUTES.

Everything worked pretty well. The GPS takes a while to connect and didn't work that well. Sometime it doesn't want to connect. This is my son's phone, I use a Kaiser. The Kaiser works better. I'll bet the official Sprint ROM due in March will work very well with GPS.

I hope this helps.
