Recently we saw how to root your Sprint HTC EVO 4G, this method works very well but it has some limitations like the inability to write a system or recovery while being in Android (it was possible only through the recovery mode). As usual the folks at XDA worked hard and have now fully rooted the device enabling full control over it. See the instructions after the break!

All the credits go to toastcfh, keishou, maejrep, Flipz, Paul and Amon_RA for this hack.

Follow those simple instructions to fully root your HTC EVO 4G:

1. You need a rooted HTC EVO 4G, if you haven’t rooted your device yet use the following post @ How To Root your HTC EVO 4G
2. Start by doing a Nandroid backup since your device will be wiped out
3. Download the files you’ll find @ http://forum.xda-developers.com/showthread.php?t=701835
4. Unzip the following files: flash_image.zip and mtd-eng.zip
5. Copy the files you extracted to the root of your SD Card: flash_image and mtd-eng.img
6. On your computer open up a command prompt and type:
   adb shell
   cat /sdcard/flash_image > /data/flash_image
   chmod 755 /data/flash_image
   /data/flash_image misc /sdcard/mtd-eng.img
7. Once it is done, copy PC36IMG.zip to the root of your SD Card.
8. Turn off your device
9. Reboot it in bootloader mode: Hold Volume Down and Power
10. The PC36IMG.zip file will be found by your HTC EVO 4G.
    When asked if you want to flash, select Yes
11. Once it is flashed it will ask you if you want to reboot pick Yes
12. Your device will reboot, wait for Android to be loaded.
    Copy recovery.img to the root of your SD Card.
13. On your computer open up a command prompt again and type:
    adb shell
    cat /sdcard/flash_image > /data/flash_image
    chmod 755 /data/flash_image
    /data/flash_image recovery /sdcard/recovery.img
    reboot recovery
14. You’re now in recovery mode, using the menu wipe the data and the Dalvik cache
15. Go to nandroid restore and restore your previous ROM setup.

You’ve now fully rooted your device, you can reboot into recovery, write to system while being in Android and so much more!
