It's all good, I got his instruction using the hboot and
Removing the battery after flashing Rom.
But I wanted to try using abd on terminal.
first off,worm makes some good points. if you need a rom thats 100% ready and stable this isnt it,yet. you may be better off holding out. eventually there will be more leaks,and the kernel source code will be released,wich will make all the 2.3/sense roms fantastic... same stability as the current froyo roms.
if you are ok with the fact that it might have issues,and you might need to flash the stock radio back and go back to froyo after playin with it a couple days, then flash away
you are prolly making the adb part of it to be bigger than it is in your head. you dont need to push any files,or copy and paste a bunch of code.
all you need to do is download rom and radio,and transfer to phone via usb. rename radio PG05IMG. put phone back in charge mode.
open your command window. i like doin stuff in adb,so at this point i made sure adb was seeing my phone(type "adb devices"),then typed "adb reboot recovery". wait for phone to reboot into clockwork. on the phone,make a backup,wipe data/cache/dalvik,flash the rom. when its completely finished flashing,(at the point you would normally select "reboot system now" on the phone) simply type "adb shell" then "reboot bootloader" in your command window. your phone will boot into fastboot mode,use the power button to select hboot. if the sd card is properly formatted(FAT32) and the radio is correctly named(PG05IMG.zip) hboot will find the file,unpack it,check it,then ask you if you want to update. tell it yes. reboot when its done,and enjoy.
also maybe i should give my bootloader speech:
flashing things in a security off bootloader is one of the most dangerous things you can do to your phone. it will not do any security checks,and will flash literally anything that you package up inside a correctly named IMG file. flashing the wrong thing,or an incomplete thing, can turn your phone into an unrecoverable paperweight.
the md5 sums are provided for good reason,so make sure you compare them(i check on the pc,then again on the phone) to the ones listed before attempting to flash the radio,or anything in hboot.
