Is it all good to go, or is something wrong? (Unable to mount storage).
As long your storage is accessible, it should be alright. Though if it's 0MB in size you might need to factory reset the OS without creating a password or PIN, and test if you can access storage from your PC.
- From the device, I can use adb sideload to upgrade TWRP and any other .zip or .iso I want, correct?
Yes.
- There is an option to make a backup. However, I somehow cannot save the backup to my computer via the usb cable. Why is this? My computer (ubuntu 23.10) shows the android device and I can cd to it.
You can do that with adb, while the phone is in TWRP and connected to the PC, run the command bellow:
adb backup --twrp
Then on the phone, it will ask which partitions you want to backup and save it on PC. Do not disconnect until the backup is finished.
- I wanted to use TWRP to locate bloatware and delete it. However, I don’t know what directories I should start looking for to get rid of facebook and degoogle the device.
Mount the system partition and delete the app folder inside system/app or system/priv-app.
ETA: according to xda, to boot into recovery mode I have to press power + vol down a while during booting and let the buttons go. However, the only way to boot into recovery that works for me is to boot to fastboot from the device and load fastboot oem reboot-recovery from my computer’s terminal. If any of you could help with the correct keys and time (when to let go), let me know.
These are the correct keys but when the phone is booting up, hold only the vol down key to enter recovery.
