I can't get this phone to boot up anymore ! As of now after flashing the rom to it that I got using WWR It doesn't even show the NUU logo anymore! It stays black screen the entire time and just bootloops? This is a secure boot phone so Is there something else that I should maybe flash besides using spFlash tools . I know the full ROM is on the phone because SP Flashtools did a full flash of the data but after when I try and turn it on it just bootloops?

Is the bootloader currently unlocked?
Models with secure boot don't play nice with flashing backups on a locked bootloader...not that an unlocked bootloader is enough.

Initially I did unlock the bootloader but I think my mistake was trying to root the phone using the older traditional method of magisk,patch-boot,flash-boot, disable verity/flash-vbmeta. At first I didn't know that the Nuu A23 was a secure boot phone. Also I need to study up on the process for how to Root Android 13 phones with secure boot.

If your WWR dump was done before it got bricked, then it's still usable.

Was this what caused the bootloop?
Is the device A/B?
Which partitions are contained in your WWR dump? Share a screenshot of its content or a link to the dump.

So I purchased a different phone called a Maxwest astro A63 ( Android 13) and I tried to flash the stock boot modified with Magisk same with the NUU A23 and it doesn't work. I just ended up bootlooping it again. There's obviously been some changes to Android 13 security and newer versions compared to Android 12 and earlier so can someone please get me up to speed because the old standard root method of magisk,patch-boot, fastboot,vbmeta-flash, patched-boot flash...no longer works.

How did you get the boot.img? Was it from a firmware or dump for the device?

Neither! I got it from XDA! Because its a cheap phone I assumed it was likely that the boot.img would be the same for all build versions but apparently after Android 13 that's no longer the case? Im not sure maybe Im just using the wrong method? Im getting another phone just like it in a few days then first of all I will do a full dump. https://xdaforums.com/t/maxwest-a63-andr...t.4679163/

The Maxwest A63 and NUU A23 are different devices, aren't they?

Have you done a full firmware backup of the phone (except userdata) in its bricked state?
