I got a replacement phone recently and it came loaded with FRG83D. I used ABD and some nice instructions to gain root and add busybox, but haven't done anything else. I dont want any custom ROM this time around, or to change much. I may play with another kernel for overclocking later, but for now all I want is what I have with the ability to backup/restore images. Previously I was on a stock-like ROM and had nandroid backup for recovery.
Ive found and read a bunch of tutorials here about adding a custom recovery image. I did it once before, but it's been a long time. My concern is that these are all either part of a bigger easy update/root/rom package which I am not interested in, or they are old and written for 2.0-2.1. Will these instructions still work? here and here
Alternately is there a better method, better instructions or something more relevant to my version and what I'm trying to do? Keep in mind that I am already rooted and running the version I want, and it is stable, so I don't want to change anything except to add the ability to backup/recover. Any help is greatly appreciated.
