Hi ! how do I know my twrp is exist or not?my current rom is EvolutionX 7.3.How to update to newest verion.
First, about the twrp.
If you havent done so already, first
download the twrp zip file to your phone storage.
Long press the Power button and select Advanced, then select Recovery. It will then boot into twrp if it is there.
If twrp is not present, you will most likely have a more basic recovery that it will boot into instead.
There will probably be an option to "Apply update",and from there you should be able to select the twrp zip file and flash it from there.
After this you can reboot to recovery again and you should have twrp.
Next, how to update.
Since you are on 7.3 you are on android 13 already, I think you should be able to update by following the instructions posted by

If you did install twrp by the instructions I wrote above, you can skip step 2.
Also not about step 3. In my case it look like the internal storage was not automaticly formatted by installing the adder-zip and I was unable to proceed.
At step 4, in case you only get error messages and are unable to flash the new rom, then try to manually format the internal storage before trying to flash the rom.
EDIT: For an additional read. Here is a
guide explaining a bit about how this A/B partitions work, and also there are mentioned why you need to flash twrp again after flashing a rom. At least I found it a bit less confusing after reading it
