Or, "how I learned to stop worrying and love the root". As discussed elsewhere, I've been a Galaxy owner since release day on O2 UK and have been following the forums here for a while. I've had all the usual problems (NPS being useless, etc) and found the forum to be invaluable, so thank you. I wanted to update the firmware, but found there's almost too much information around. Lots of updated / contradictory information, and some of it requiring convoluted hacking of text files etc. I eventually took the plunge, and made notes as I went. Hopefully, this will be of help for other new users. After reading, I decided there were two stages to this. First, back up the phone so if it all went west I could roll back. Second, get the firmware on it. Booting in various modes: With the phone off: Fastboot mode - call + power Recovery mode - vol-down + call + power (hold home + back to exit) Download mode - vol-down + ok + power To enable root and back up the phone: (update - this method appears to have been blocked as of firmware rev. II5, should still work for IH8 and earlier) To enable root and back up the phone: Get recovery image from http://www.megaupload.com/?d=8SAFKOIN (see http://forum.hdblog.it/showthread.php?t=3995 for details) Get recovery flasher from Android Rooting in 1-click (limited time only… until it gets patched) Copy recovery.img and rectools.tar.gz files to /sdcard (tar.gz must be the root of /sdcard) copy the recovery flasher .apk to /sdcard and install it Run recovery flasher Choose "backup recovery image" just in case Enter sdcard/recovery.img as the path Choose "install custom image" Boot into recovery mode Run a nandroid backup Enable root if desired Reboot To flash the firmware: Get Odin + H7 firmware from MEGAUPLOAD - The leading online storage and file delivery service Get H8 firmware from RapidShare: 1-CLICK Web hosting - Easy Filehosting and unizp it to give you a .tar file. Alternatively, you can use the latest I5 firmware here, there's links to it elsewhere on the forum - I'm using H8 as an example as this was the latest when I wrote this. Edit the .tar file with 7-zip to remove cache.img (to remove CSC branding) - 7-zip handles .tar files in a vaguely sensible manner, unlike things like WinRAR. 7-zip can be had from 7-Zip Boot phone in Download mode Run Odin Follow instructions here The Chronicles of Cjeni a.k.a. Dejan Cencelj: Flash ROM Samsung I7500 Galaxy for dummies - essentially you're adding your freshly modified .tar as a one-file update, along with the orion.ops file supplied with Odin. The web page is nice and clear. Ooh, new firmware.
