Update Evo 3D CDMA to Latest Update 2.17.651.5 ( Rooted + Stock)

Sprint has just started to push out a new firmware update for its HTC EVO 3D users, namely updated version 2.17.651.5. The new update was designed to provide users with security enhancements. Now before you jump to any conclusions: no, this isn’t the highly awaited Ice Cream Sandwich update 🙂  Rather, the changelog is rather short, only including “Security Updates.” Users on Sprint community forums are also reporting impressive battery life performance enhancement.

The update is likely to be pushed out to devices starting today, Jan 17th. XDA developer TrevE has managed to post an updated zip file of the OTA update in his thread. The ROM is as close to stock as possible, and includes root access. You can download it from the links below, quoted from the developer’s thread:

Full System/boot:

 Radio File

Rename to PG86IMG.zip, put on root of sdcard, adb reboot bootloaderRADIO: PG86IMG of radio and rcdata ONLY – PG86IMG_2.17.651.5_RADIOONLY_1.06.00.1216.zip. MD562f411bdbc8e42c86c6b6eb0f898138chttp://www.multiupload.com/GF8F38DVDN

Warning: This update is compatible only with the HTC EVO 3D CDMA version. Please check your handset  model before flashing this. Flashing it on an incompatible device might render the device unusable. The steps mentioned here are considered risky; so only proceed if you know exactly what you are doing. You have been forewarned!!!

Note:  The PG86IMG.zip file contains a new radio. If you are on Hboot v1.4, you can download the file, rename it to PG86IMG.zip, transfer it to your external sdcard, reboot into bootloader and it should get flashed. However if you are on the newer Hboot v1.5, you wont be able to flash a radio file from within the bootloader. To do so, you would need to unroot, and  flash back to stock, apply the update and then reroot. While this may seem frustrating, unfortunately its the only way to update radios, if you’re on Hboot 1.5 🙁

Pre-Installation Requirements

  • Installing/Flashing this ROM will erase your apps and data. So, it’s very important you back them up, before proceeding further.

  3. Connect the HTC Evo 3D to the computer via USB.
  4. On the computer, open terminal and run the following commands:
    adb push PG86IMG.zip /sdcard/PG86IMG.zip
    adb shell md5sum /sdcard/PG86IMG.zip

    NOTE: The md5 should match up the provide the original download location. If not, redownload & try again.

    adb reboot bootloader
