Samsung Galaxy – Flashing and rooting overview
Flashing and rooting overview
這主要是記錄刷還原副系統的基磋步驟. 文中後部刷的主系統 Android ROM ver 是歐版, 本地人沒有特別需要的話, 就應改用港版或其他更新的 Rom 代替. 執筆時最新的港版 ver 為 I7500ZHII4.
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 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
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
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.
