HTC Evo 4G Jelly Bean Update: AOKP Based on Android 4.1 Arrives!


AOKP ROM – famous for its advanced customization options – is now available for the HTC EVO 4G in the form of an unofficial build, bringing Jelly Bean to the device with all its new features along, such as a smooth as butter interface, Google’s voice recognition helper called Google Now, a smarter keyboard, better accessibility, an improved and actionable notifications menu, and a lot of others, along with AOKP’s smart customization options.

NOTE: This is an early preview build of AOKP ROM, so there are some things that don’t work and the ROM may also have some bugs and issues present, which you should keep in mind before trying the ROM out. Also, don’t expect to find many customization options of AOKP to be present here, as those haven’t been added to the AOKP Jelly Bean code yet.

Here’s a list of known issues in the ROM, quoted from the development page:

- NO Camera
– NO 4G (did you really expect that to work???)
– NO Netflix, Hulu Plus, HBO or whatever you guys watch….is not working!
– Bootanimation loops over and over again and looks like it bootloops (will fix in next version)
– A few other minor things

Read on for the installation instructions for AOKP Jelly Bean on the HTC EVO 4G.

Jelly Bean ROMs for other HTC devices such as the AT&T One X, myTouch 4G, Desire Z or the One S can be found herehere, here and here respectively.


This ROM and the guide below are compatible only and only with the HTC EVO 4G. Do not try it on the EVO 4G LTE.


The methods and procedures discussed here are considered risky and you should not attempt anything if you don’t know completely what it is. If any damage occurs to your device, we won’t be held liable.

How to Install AOKP Jelly Bean ROM on HTC EVO 4G


  1. This procedure will wipe all your apps, data and settings (but it will NOT touch your SD cards, so don’t worry about those). Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.
    NOTE: Don’t forget to at least make a backup of your APN settings, which you can restore later if your data connection does not work after installing the ROM. Use the backup guide to find out how.
  2. Make sure the bootloader is unlocked with S-Off and AmonRa recovery is installed on your device. You must use AmonRa recovery to flash this ROM.
  3. Download the latest version of the ROM from the official development page.
  4. Copy the downloaded zip file to the SD card on the phone (do not extract the files).
  5. Boot into recovery. To do that, turn off the phone. Hold Volume Down & the Power buttons until the device boots to recovery, or HBOOT. If the latter, wait until the menu appears, then press Volume Down to highlight RECOVERY then Power to select and then boot into recovery.
    In recovery, use the volume buttons to navigate/scroll and the power button to select.
  6. Perform a Nandroid Backup of your existing ROM, so that you can always restore it from recovery if something does not work out with this ROM. To perform a backup, select Backup and Restore –> On the next screen, select Backup again. Go back to main recovery menu after backup is complete.
  7. Select wipe data/factory reset, then select Yes on next screen to confirm. Wait a while till the data wipe is complete.
  8. Select mounts and storage, then select format system, and confirm format on next screen. Then, go back to the main recovery menu.
  9. Select install zip from sdcard, then select choose zip from sdcard. Scroll to the ROM file on the SD card and select it. Confirm installation by selecting Yes – Install on the next screen. The ROM will start installing.
  10. After the installation is complete, go back to the main recovery menu and select reboot system now to reboot the phone and boot into AOKP. First boot will take up to 5 minutes.
  11. Returning to Previous ROM: To go back to your previous ROM, boot into recovery (as given in step 5), select backup and restore then restore your previous ROM by selecting it from the list.
