[8125, K-JAM, P4300, MDA Vario Software Upgrading] mimarsinan:
Hi,

First, I ran some tests on my kjam. The kjam came default with the kjam rom on it, naturally. I wanted to CID unlock this phone, so I downgraded the rom to button's "beer glass" splash screen rom. Then I was able to run aWizard successfully to CID unlock the phone. I then upgraded back to the original kjam rom. Both the downgrade and the upgrade went smoothly.

I then found out I wanted to customize my splash, so I downgraded again. I customized the main splash (not the HTC one) using aWizard. Worked like a charm. I also ran some extra itsme tools to read and write from rom in some locations I needed access to.

Everything was working great at that point. But the downgrade ROM didn't properly respond to some of the printed keys on the kjam keyboard, so I thought I should upgrade again. However, this time, I decided I want to keep my splash etc., so I tried to upgrade only my radio and OS rom, as backed up by aWizard previously, from the original kjam ROM. I used aWizard to restore the selected areas of ROM, rather than the RUU tool.

I upgraded the radio ROM, didn't reboot the device to keep the radio and OS in sync, upgraded the OS ROM, just as that was happening, the phone received a phone call (or text message, do not know which), and hung. While the aWizard eventually completed the upgrade, the phone did not reboot or "un-hang" itself after aWizard displayed success (there was no error on the console window).

So I soft rebooted the phone. The splash screen came, but without a GSM version on it. I was like, "shoot!", something bad must have happened, lets just put the full kjam rom on this, and get it over with - never mind the custom splashes. So I went into bootloader and applied the kjam rom.

Now it displayed the GSM version as well on the splash screen, but again, it never left the splash screen. I was like, again, "shoot!", lets just go back to that old downgrade ROM with the funny keyboard, then we can figure this out again. So I went into the bootloader and applied the downgrade ROM.

Alas, the beer glass splash screen remained hung as well! And actually, since then, I've downloaded and installed ALL ROMs I've been able to find - ALL of them have hung.

My bootloader is still working fine and dandy...any idea why this might be happening? Was the problem in the phone call I received? In using aWizard without rebooting? In using aWizard at all? In trying to manually edit the machine ROM using itsme tools (mind you, those edits worked fine until I started updating the GSM/OS ROM)?

And oh, after hanging for a while on the splash screen, the phone screen starts flickering real bad (whilst still on the splash); in case that provides any help.

To clarify the bootloader situation a little more:

I've got FULL bootloader capability. I can mtty into it, I can write commands, I can install full new ROMs from the bootloader, etc. So this would seem to indicate my phone may not be a brick yet...its a brick that can display changeable wallpapers I even figured out how to draw progress bars and write text to the bootloader screen using MTTY commands. Fun, actually! Its a $700 etch-a-sketch pad :P
