Default Attention! HBoot 2.22 and it's risks. A small Guide for don't losing your data.

Hey folks,

after making few mistakes in the past flashing wrong recovery's and unlocking the One Mini with HBoot 2.22 I thought of making a little information thread for all users, who want to unlock/root/flash custom firmware on their phones.

Here are just few important things you have to check before flashing or unlocking:

Check if HBoot is 2.22:

First, go into the bootloader by pressing and holding the "Power + Vol. Down" Button with the phone on OR off, as long as the phone is in Bootloader.
Now you can check your HBoot Version.

- If it says HBoot 2.21 or lower, you just have to backup all of your SD-Data, just for security reasons.

- If it says HBoot 2.22, also backup your Data AND be careful which recovery you want to flash.


If you like TWRP, please DO NOT flash Version or lower. WHY isn't really important for new users, just don't do it.
Few changes were made since HBoot 2.22 and older recovery's could instantly wipe all of your data and/or don't let you access your internal memory ("SD-card") for making a nandroid backup.

TWRP made a new Version for you, so please use this one. Head over this link, for your download. If your are on HBoot 2.21 or lower, you can also flash the new one.


If you like CWM, it's the same procedure, as older Versions may not work well with the new HBoot. For me, I cannot find any updated version and I am not sure which version works fine with new HBoot 2.22.
CWM is the newest one, eventually somebody can confirm, that this versions works with the HBoot.

For the download, just follow this link and scroll down to the "m4" device. But I can say it again, please use only TWRP for now.

So for now, please use TWRP, it should work with all Custom Firmwares so far.

One last important thing: I am not 100% sure, if flashing a new recovery, even the new one, would wipe your data or not. So please be aware, that flashing a new one could erase all of your app data/settings/contacts/data on SD.
If it is possible for you, use the HTC Backup App to backup your data.

Hopefully I can help "newbies" to prevent them of losing all of their data by simply flashing a new recovery, just as I did.

If you have any questions, I try to keep this thread up to date and answer your questions with my knowledge I earned the last few days.

Have fun with your phone and a nice day!
