Can we upgrade/downgrade using serial (LTP1)?

[goatieman]

I was running ROM 3.20.06 and Radio 4.21.00.

I read everything on here about upgrading to ROM 4.00.05 and figured that I was ready to upgrade. Many others experienced no problems when upgrading from 3.20.06 to 4.00.05.

The upgrade procedure was complete and I hard reset.

The XDA turned on and a white screen with "Test Only", "Not For Sale", A Microsoft Windows Powered logo and the Platform information appears and that is all that happens. In other words, it is fucked and won't do anything.

Does anyone know whether ROMs can be installed via, LTP1 seeing as though the USB will not communicate? Will I get the same problem?

A reply would be nice. :)

I forgot to mention that I will be connecting my USB cradle to a USB-2-LTP1 cord. If that helps anyone reply then sweet.

Get yourself an sd card reader writer and an sd card of 64 meg or more. Use the tools on the forum to program the rom to sd card, then you enter bootloader mode and your phone will burn the rom from there. As for the lpt port, no way that I know of.

:roll:

Is it possible to change the XDA into bootloader mode if the XDA is not functional? (I cannot do anything, just a white screen is what I see)

I know that this sounds stupid, but don't mess with it for about 15-20 minutes. It seems that if the radio stack is screwed, the OS takes forever to boot. I have been doing OS installs for several months, both directly and via an SD card, so I was comfortable with the process. I had NOT ever done a radio stack upgrade as I had the latest (& only one) that AT&T had released. With the "official" rollout of WM2003 by AT&T, I decided that I liked my custom 2003 ROM that I had cooked a couple of months ago, but I did want to try the newer radio stack. Well, all hell broke loose. At first, I had a PPC that would not boot. So, I did a new flash of the OS via SD chip. It seemed that it too was locked (ie the initial splash screen with OS info at bottom and then it seemed to freeze). Then I read in another thread that someone had noticed it took about 15 minutes for the thing to reboot after a failed radio stack upgrade. And so after giving it time, sure enough, my PPC did finally boot.

The bad news is that I have NOT been able to get the radio stack reinstalled. I have followed all the tips and suggestions, but no luck. If you find that yours finally does boot, then goto start, settings,system info and see if there is info about the radio stack. If it is blank, then you have not radio stack and that is why the long boot cycle.

Ok, when I performed the upgrade, I believe it was only the ROM that upgraded. The radio version is the orignial XDA upgrade which was released to the public as a genuine radio (B) upgrade. I'll look into the SD boot load. Will it automatically install from the SD card? Anyone got any idea?
