HTC One SV TWRP Recovery: downloads and installation guide

HTC One SV might have grown a bit older now, but it’s still right there in terms of development support. The One SV just got the latest TWRP recovery available, for flashing ROMs and mods, or taking nandroid backups and what-not, and if you love to have latest and greatest of modding tools like us, we’re sure you’ll feel very happy about the TWRP v2.8.7.0 for One SV.

Of course, as mentioned in the guide below, you will need to unlock bootloader of your One SV for this, and only then device will be open to modifications. Once done, you can use the fastboot method, as given below, to install the latest v2.8.7.0 of TWRP recovery on your One SV.

Note: If you are doing this for the first time, we recommend you create a full backup of your device right after installing the TWRP recovery, so that when an OTA comes, you can restore this backup — which includes 100% stock system — to make device compatible with updates. You will also need stock recovery for OTA updates, which is easy to get anyway. Lastly, after restoring system, you can easily flash OTA update using TWRP recovery only as a good alternative solution.
