[EVO 4G Android Development] XenonV:
*Disclaimer*

First i would like to say that this is not my guide, i dont want any credit for it, i just wish to share it with those that need help rooting their EVO's.

This was very easy to do (just read thru it once or twice to be safe before starting the process). You are 100% responsible for anything that goes wrong. it is not my fault, XDA's fault, or anybody else' fault if your phone bricks/explodes/causes world war 3/your dog to explode/or a nuclear wave.

Here’s how to root your HTC Evo 4G on HBOOT 2.18 with S-OFF!​

Step 34. If you want S-OFF, do the following to allow RUU flashing back to 651.1.

First, make sure USB Debugging is checked ON under Settings->Applications->Development.

Step 35. Go back to command prompt and type:

adb push flashimage /sdcard/.
adb push mtd-eng.img /sdcard/.

adb shell
su
cat /sdcard/flashimage > /data/flashimage
chmod 755 /data/flashimage
/data/flashimage misc /sdcard/mtd-eng.img
exit

For Mac, replace “adb” with “./adb-mac”.
For Linux, replace “adb” with “./adb-linux”.

Step 36. Next connect your Evo 4G to your computer as a disk drive and copy the PC36IMG.zip file to the root directory of your Evo 4G’s SD card.

Step 37. Type:

adb reboot bootloader

Step 38. Your phone should now say “LOCKED (OOW)”. And should check for the PC36IMG.zip file. If it doesn’t (which happened to me), try using another micro-SD card or format your micro-SD card and repeat from Step 36.

Step 39. Hit the Volume Up button to start the update process. This will get you back to software version 651.1, which allows you to use Revolutionary to get S-OFF. You can also flash an older version too if you want but that’s outside the limits of this tutorial.

Step 40. Your phone should reboot once, just let it do its thing.

Step 41. When everything is done, you will get an option to reboot your phone, hit Volume Up to reboot.

Step 42. You should now be back on sfotware 651.1. Let’s go root it using Revolutionary root method. Make sure USB Debugging is checked ON under Settings->Applications->Development.

You can also see original step-by-step instructions for rooting using Revolutionary here.

Step 43. Go to command prompt and type “revolutionary.exe” and copy the serial number.

Step 44. Go to the website Revolutionary.io and click on “Download for Windows”.

Step 45. Choose “Windows”, HTC Evo 4G, 2.16.0001, and paste your serial number. Click on “Generate key”.

Step 46. Copy the beta key.

Step 47. Go back to command prompt and paste your beta key and hit Enter. Your phone should now become S-OFF after couple reboots. Just let it do its thing.

Step 48. Your phone should say “Revolutionary” with “S-OFF” and HBOOT 6.16.

Step 49. You can stop here if you are going to flash a new custom ROM anyways.

You will be on 651.1 OTA plus root plus S-OFF.

(If you want latest 651.3 OTA rooted, keep going)

If you want to be rooted on latest 651.3 OTA plus root, copy the file 4.67.651.3.zip to the SD card of your phone.

Step 50. And delete PC36IMG.zip file as it will interfere.

Step 51. Reboot into bootloader by holding down Volume Down and Power button. You know the drill by now. And choose “FASTBOOT”.

Step 52. Go to command prompt and type this again to re-flash recovery as it has been wiped out during OTA 651.1 zip install.

fastboot flash recovery recovery-RA-supersonic-v2.3.img

Step 53. Choose “RECOVERY” to enter recovery.

Step 54. Choose “Flash zip from sdcard”.

Step 55. Choose “Choose zip from sdcard”.

Step 56. Choose the file “4.67.651.3.zip”

Step 57. When that’s done installing, go ahead and install the file “CWM-SuperSU-v0.87.zip”. This will give you root (again) on 651.3.

Step 58. Reboot and you will find yourself with the latest Software 651.3 (just like you started) with root and S-OFF.

Time to get all this done = around an hour.

Having the latest OTA, rooted with S-OFF so you can go flashing new ROMs on the bus or the plane = Priceless.

Enjoy!

Q&A

Q: Why do I need S-OFF?

A: If you want to install new custom ROMs without a computer.

Q: Can I flash a new custom ROM with S-OFF?

A: Yes you can but you must boot recovery from fastboot, get your phone into fastboot USB mode, then the command is:

fastboot boot recovery-RA-supersonic-v2.3.img

You must do this everytime you want to flash a new ROM if you are on S-ON.

For those on S-OFF, just flash normally from recovery.
