need some advice - restoring hermes for warranty repair. os done, radio and BL left

[washi]

Hi,

i must sent my hermes to repairs. so i have to restore it to wm5 and old bootloader.

i have some problems with the gsm module. sometimes i get "no gsm" in the bootscreen and after boot no phone functions. Some time i the radio shows up in boot and i get phone functions. the problem did not appear after a flash. the last flash a month ago.
it seems that the hardware that there is a loose connection. when i make a test call and knock the phone (softly) the phone connection is lost. the "end call" button does nothing and after a while the whole os freezes.
has someone another idea than faulty hardware?

OS is restored to original with the help of mrvranx guide.
whats left is the bootloader and the shipped radio rom.

Bootloader screen shows:
Herm 300
IPL-1.04
SPL-2.10Olipro

Radio Rom is 1.47.30.10

Im a little concerned about mrvranx warning: "If your radio version is currently HIGHER than 1.27.00.00 then it is very likely the radio bootloader is version 0108, this WILL NOT allow the radio to be downgraded to a radio containing BL 0106 and will result in a "NO GSM" error"

but on the next page is a guide to flash the bootloader back step by step to the original. is this method save? and does anybody know which one was the shipped one (t-mobile germany).

last the radio. i can't remember which was the shipped version.
and can i flash whithout problems back to the original? somewhere i read about problems because of the bootloader.

and the last question :)
in what order must i do this. first radio then the bootloader is right?

many thanks in advance.

just today I had to get my old TYTN ready for warranty/repair.

I followed mrvranx's guide to downgrade my bootloader and it worked flawlessly. I did it all from an XP computer as I was having issue on my Vista machine. Follow it to a T and you should not encounter trouble.

As for the order, I don't think it matters. I did my radio last if you just wanna follow my lead.

As for determining the radio and boot loader version - I'm with Rogers in Canada, they send me my replacement device before I send them the faulty one. I just go into bootloader mode (power on the right side+ok on the left side+reset button at the bottom) and verify the version.

just checked my radio bootloader version. its 108.
so i wont be able to flash a radio < 1.3x?
which is unfortunate because the t-mobile germany never actually offered an official update :/

i just hope the handy will pass with the old os and old bootloader but newer radio.

I have to send my phone in as well and didn't know if it was really necessary to do all the downgrading and stuff? i guess can't hurt to be safe though huh
