I just bought my son a used Moto X (2013). He's already set it up and installed his apps. When he accepted an OTA update (4.4.3 to 4.4.4) it failed and we discovered that TRWP recovery was installed. He would like to revert to a stock recovery so that he can accept Lollipop OTA when available.

I can easily install 4.4.4 with the images and instructions from Motorola but this would cause him extra work as he would have to set up the phone again.

I assume I can just flash the stock system and recovery image but Motorola only offers the images for 4.4.2 and 4.4.4 not the 4.4.3 that he has installed.

Would it be safe to install one of those? Which one? Would that preserve the apps he's already installed?

Thanks in advance.
