Reports are coming in that users are able to successfully download and install the latest OTA from HTC and Sprint for the HTC EVO 3D. This update bumps your version number to 2.08.651.2, bumps Android up to 2.3.4, and bumps Swype up to version 18.104.22.168626.28659.
Additionally, this update will allow you to uninstall (or hide) additional apps from your app drawer, including the Green Hornet shortcut and Spiderman. However, Google Talk on the EVO 3D still does not support video chat, similarly to the HTC EVO View 4G, even though Android officially supports it in this version.
Users are also reporting miscellaneous performance improvements, but before you jump the gun and install this OTA, here is what you need to know.
This OTA will update your HBOOT to 1.50, which means that – as of now – Revolutionary will not support unlocking the bootloader on the EVO 3D after this update. This may or may not matter to you, as this update does prepare the EVO 3D for the forthcoming official HTC bootloader unlocking tool.
As you can see to the right, the HBOOT now says that it is locked, even though I previously rooted through Revolutionary and I clearly have S-OFF. This "locked" warning is therefore unconnected to the actual state of the bootloader, which is most likely programmed to display this until HTC's official unlocking tool is used.
Therefore, if you have already rooted your device using Revolutionary, this OTA will not necessarily cause you to loose root. However, for most users, I would still recommend waiting until a rooted ROM based on this update is available for you to flash.
Update: A stock, rooted ROM (odexed or de-odexed) by xHausx is now available for your flashing delight, so you don't have to do all the extra work I detail below – unless you want to.
If, and only if, you are an advanced rooted user and would like to apply this update the "official" way, keep in mind that you will need to flash the stock recovery that shipped with your phone (not Clockwork or the TeamWin Recovery Project). You will also need to revert your system/app folder back to its original state (in other words, replace any system apps you removed with Root Explorer or a similar app).
Once these two prerequisites are met, you can safely download and install this OTA update. Afterwards, you will need to re-flash your custom recovery of choice and Superuser. In my experience, the most current stable version of Superuser (version 22.214.171.124) does not work after this update, but the most recent beta works just fine (version 3.0 beta 3, available here).
If you haven't received the OTA update yet, you can check for it by pressing Menu > Settings > System updates > HTC software update. It will also be pushed out to users who haven't yet updated on August 23.
How is this latest OTA update working out for you? Have you noticed any other changes or improvements, or the introduction of any new bugs? Be sure to let us know in the comments!
