My next plan was to test the process for uninstalling a number of system apps that I never use. Before going ahead with this, I intended to make a backup of the current system, just in case the doom and gloom about this potentially resulting in other apps no longer functioning proved to be a problem. However, booting the phone into fastboot mode, and selecting recovery, didn’t launch the TWRP Custom Recovery software as I expected, instead I saw a “dead” Android soldier and the ominous message: “No command”.
TWRP’s help file says: “Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don’t follow this step, you will have to repeat the install.” So, it would appear that I missed a critical reboot after installing TWRP and the recovery software was indeed “replaced” (i.e. removed). The next thing to do is to reinstall TWRP.
Fortunately, now that we have a rooted phone, there are two utility programs that will speed us along the way to a full recovery. The first is the Official TWRP App, available for installation from Google’s Play Store. This app provides a front end to the custom recovery software, including the ability to both download and install the installation software image on the phone. The second is Quick Reboot Pro, a free ad-supported app, which is also available from the Play Store. On a rooted phone, this gives a simple menu with options that include a direct link to the phone’s recovery software. This avoids the need to use the power and volume-down keys to access fastboot mode in order to select the Recovery option.
Having installed the TWRP app, the first time you run the program you are required to select the relevant device. In my case, the Moto G3 was listed as “Motorola Moto G 2015 – osprey”. Next, you need to select the recovery image to be downloaded. (At the time of writing, the most current version was twrp-18.104.22.168-osprey.img).
Back at TWRP’s main menu, choose the “Select a file to flash” option and browse for twrp-22.214.171.124-osprey.img. Next choose “Flash to Recovery” and confirm that you wish to install this version of TWRP. The program will indicate completion of the installation as: “Flash completed successfully”.
We can check this very easily using Quick Reboot Pro. Launch this app and select “Recovery”. The phone will reboot, and the teamwin splash page will be displayed, indicating that TWRP Custom Recovery is once again available on the phone.
While we have TWRP running, now is a good time to make a system backup. Choose the Micro SDcard as the storage location for the backup. In my case, in just over 16 minutes, TWRP created a 6.27 GB folder at TWRP/BACKUPS/ZY2234QGLB/2017-09-07-15-
50-50-MPIS24.65-33.102-2-11. With a file that large, and a name that long, it just must be a full system backup!
