You can, but I recommend against it. A few people have reported serious problems after using Easy Root. Your best bet is to follow the rooting instructions in the thread entitled "The guide to all things root related". It's a little more time consuming, but it is the best way to get working root without problems. Just make sure to follow the directions exactly. Plenty of us are here to help if you get stuck.

Once you're rooted via that method, you can just install a rooted 2.2 ROM.

 

Its a long process, but this guide (even though it says from 2.2 to rooted 2.2) will get you the same results. its using the same SBF file to flash the recovery partition that you would use to root 2.1. Follow it step by step and it will get you there. If you want to keep all your settings and data, use one of the stock rooted roms he has listed in the steps and DO NOT WIPE. going this route, you will end up with the 2.2 OTA with root access. good luck

stock is 600 on 2.2. to overclock you will have to flash different kernals. check out this thread http://androidforums.com/all-things-root-droid/136508-guide-all-things-root-related.html and read up on flashing kernals. as far as wifi tether, about all the custom roms have it built in.

 

Those steps just verify the download/files match what they should be.

I don't think flashing just the recovery .sbf will wipe your info, but you will probably need to wipe it anyways when you flash the new ROM.

Sapphire is a good rom, but I personally prefer cyanogenmod. jrummy, chevy, and pete (bugless beauty) all make pretty popular roms as well.

Any of the above will give you the ability to do what you want to do however. It all comes down to personal opinion as to which one is better.

 

If you follow OMJ's guide and load a stock rooted rom. you DO NOT wnat to wipe. doing this will save all data and apps on your phone. after you get one of those roms installed, go get Titanium Backup from the market. it will back up all your app. your contact are automatically backed up by google. once you have a Ti-BU, flash your custom roms, reload Ti-BU from the market and restore. there ya have it.

 

No, they need to stay zipped.
Check on your computer and make sure that the file didn't end up being named update.zip.zip (as it will if you rename the file to update.zip but you have your computer set to not show file extensions).

 

you still have a copy of the of the update on your PC?
Try to copy it over again. Remember not to put it inside any folders on the SD Card.
Then try steps 16 +17 again.

 

Good job

 

you know how you just added that ROM, same way. Find a 2.2 that you like (I'm on BB v.4) rename it to update.zip, throw on SD Card, reboot into recovery, wipe data/cache, allow install, then install.
Same with the Kernel that you decide to install, only you won't need to wipe data and cache.
Your contacts should be synced to google so all of those will refresh themselves after boot up

 

If you followed my guide then you are on 2.2. All you need to do is install a kernel and get setcpu off the market

 

download ROM manager from the market. makes things supper easy. you can download assorted ROMs and kernals from it and install them.

 

yup, either ROM Manager or here is a link to the roms on the site.
