How to downgrade from Miui Or JVR GB to Froyo ?

Hello , i have alot of troubles with my phone such as
1-Lag in browser ( pinch to zoom lags and browser feels laggy /choppy not smooth)
2-Lag during switching homescreens ( transition effects are laggy )
3-Crazy power drainage at a rate of 10% per hour on IDLE !!
4-any thing that could be "scrolled or switched through" feels laggy and NOT snapy
5-some apps that require mics doesn't work like ilighter ( flame doesn't respond to mic ) but mic is working fine
6-any scrolling through lists ( up and down ) lags

i have tried alot of roms , JVP , JVR , JVQ , JVH , JVO , Surface rom , F1 GS2 V6 , creskilo's rom , darky , jewu's

tried different kernels like speedmod, Darkcore , CF-Root , galaxian

all give the same effect , nothing changes

i tried to over clock....even to 1300MHZ ..... still not even a change

i asked every where , i cleared every cash , wiped all data , system , clean installs , no luck

untill people started telling me to downgrade and updater bootloader

i took it out of the box on Eclair 2.1 Update 1 , and iam not sure if that's the original

can i downgrade to froyo ? and see if i still get lags ? then flash a good GB rom ??

thanks !
