[TUTORIAL] How to make OTA update with other recovery

Hello!
I managed to do the OTA update on my HTC Desire 820. The trick is that it replaces the original recovery.
By this method you can also restore the original recovery.



1. Download the OTA Update but do not install.
Go to Options -> About phone -> Software updates



2. Open file explorer and go to Download folder (/storage/emulated/0/Download) and find zip file with update and open it.



3. Open firmware.zip



4. Copy "recovery.img" to sdcard for example.



5. Replace recovery.img

To this step I use "Flashify" app from Google Play.

Run Flashify and select "Recovery image".


Select "Choose a file" and select recovery.img


Select "YUP!" and wait.



Don't restart your device.



6. Install update

Go to Options -> About phone -> Software updates and select "Install now".


Click OK. Now your device install update.

This operation takes a few minutes.



7. Final

Managed to do the OTA update.


If you want you can install other back recovery.
In the event of the emergence of a new update you can do the same.



I hope that helped. Best regards.
