Root Using specific ROMs?

kisner · Dec 5, 2010

So, I flash to 2.2 but I'm rather confused on how to use specific ROMs. I'm particularly interested in the Perception ROM ([ROM]Perception Build 7 (CogKernel2, uv/oc, Voodoo5, tons of tweaks) - xda-developers)

Can someone please help me out and explain how to install it? I have the zImage file but I'm not sure what to do with it

you dont need an image file you need a zip file, but dont unzip it

then in this thread i explain it. i explain cognition but its exactly the same for perception. i would read through it as i answered alot of questions

Thanks! I'm reading through right now and downloading Cognition, gonna give both a go. My next question, did you flash back to JF6 or is it not necessary?

i would definitely recommend going back to 2.1. you may be able to go from 2.2 to a new rom but youll probably get a soft brick. id flash back to stock to be safe

OK, so I flashed back to 2.1-update1, rerooted and now when I use ROM manager, when it reboots (after trying to install Cognition) it says it can't find /cache/ update.zip or something to that affect. Have I done something wrong?

did you root 2.1?

kisner · Dec 5, 2010

Yup, I did

kisner · Dec 5, 2010

When it goes to install, after it reboots to recovery it says:::

-- Install from package...
Finding update package ...
Opening update package...
E:Can't open /cache/update.zip (bad)
Installation aborted

did you flash clockwork recovery, and are you in the clockwork recovery menu? if so to apply the new rom select apply .zip from sd card not apply update.zip

kisner · Dec 5, 2010

OK, so here's what I did.

I was now able to get the phone into the Clockwork Recovery menu on reboot. I then navigated: Reinstall packages > install zip from SDcard. From there, I found the folder the update.zip that came with cognition zip was located in and selected it. When I choose install, it doesn't really do anything and just brings me back to the recovery menu.

Do I have to have the update.zip in a specific location? Or does it not matter as long as I navigate to it.

the update.zip is used only for rooting. you select the cognition.zip file from the menu and it installs it, you dont even need the update.zip anymore. like when you go to apply .zip from sd card you select the cognition.zip and thats all you do. youre not supposed to unzip the cognition.zip

I think I just figured that out by accident because it's working perfectly now, currently installing. Nothing like potentially breaking your phone with trial and error

Thanks for all the help =)
