Downgrading to WM5

[Wiechers_s]

Hi There

I'm now running the original but updatet T-Mobile version but i'd like to upgrade to WM6. unless it's her in german i'd like to have a possibility to downgrade again!
Can i just flash the old t-mobile files if i'm mad of rading english all day long??
Or will i need special rom to reflash WM5??

I used the german AKU3.3 ROM and it showed 'Upgrade from V4.0.0.0 to V3.3.0.0'.
Maybe you have used an old AKU2.x ROM to downgrade?

And... try downgrading in bootloader mode (hold tape button while soft-reset until colored bars are shown, but you need different active-sync drivers for bootloader mode)

I succed to downdrade to germab t-mobile rom but i need a wwe rom ,i'm not familiar with german language,and the uk roms just don,t work .update error.

Once you upgraded to AKU 3.3 you cant go back to AKU2. The only thing that could help is flashing the prophet rom but it can be dangerous. Search the prophet section if you want to do it.

Hi vlodeck

I upgraded already to aku3, but i would like to upgrade to wm6
do you know a good way to do so ?
downgrading to aku2 does not work - as you said!

BootLoader.exe anywhere (ïîìîåìó:)) Forum

hmm ... didn´t find a description what to do, but tried to downgrade back to orginal aku2 in bootloader mode:
ERROR [296] : UPGRADE ONLY
