Developers at XDA Forums have come out with a step by step guide on rooting your recently updated HTC Evo 4G and here it is:
You will need to download hackfiles2.zip before embarking on this rooting procedure
1. Unzip the files into a directory somewhere on your computer
2. Put the files into the root of your SD card (mount the EVO as a disk drive)
3. Un-mount your phone
4. Run “adb shell” and start part1 on your phone:
5. If the script says to power down, hold your power button and turn off your phone, then turn it back on.
6. When it starts up it will ask you to open the EVO browser. open your EVO browser to https://bit.ly/ad0pRn
7. When it asks you to, refresh the EVO browser on the same page
8. Reboot your phone with “adb reboot”
9. Run adb shell as soon as you can (when the HTC logo is still showing). You need to be fast. If you get “error: device not found”, try again.
Code:adb shell /data/local/part2
10. It should print after part2 finished:
Code:crw-rw-rw- root root 90, 2 2010-07-05 19:37 mtd1
11. When your phone finished booting, flash toastcfh’s mtd-eng.img to misc:
Code:cat /sdcard/flash_image > /data/local/flash_image chmod 755 /data/local/flash_image /data/local/flash_image misc /sdcard/mtd-eng.img
