This boot comes with twrp and Magisk

Fastboot command :

fastboot flash boot_a cheryl-P-Magisk-twrp-boot.img

fastboot flash boot_b cheryl-P-Magisk-twrp-boot.img

fastboot reboot


download

Thanks @将军和妓 Making a boot file
I tried with fastboot boot cheryl-P-Magisk-twrp-boot.img and nothing happened.
I'll try properly flashing the image when I have the time to make a backup.

Anyone has been able to backup the clean Pie boot.img ?

EDIT: Tried flashing the boot image and it bootloops. Maybe device encription has to be disabled for twrp to work?

thank you so much for this
I worked after I flashed my phone to 7.1.1 and updated to 9 but when I did it again and after updated did a wipe(just going into the setting and wiping) I couldn't flash part b of the boot just got an error


:tools root# ./fastboot flash boot_a cheryl-P-Magisk-twrp-boot.img
Sending 'boot_a' (26840 KB) OKAY [ 0.840s]
Writing 'boot_a' OKAY [ 3.657s]
Finished. Total time: 4.503s
:tools root# ./fastboot flash boot_B cheryl-P-Magisk-twrp-boot.img
Sending 'boot_B' (26840 KB) OKAY [ 0.659s]
Writing 'boot_B' FAILED (remote: 'No such partition.')
fastboot: error: Command failed

(EDIT: I'm retarded didn't notice the uppercase B but it seem they really didn't care of Gen1)

I made the mistake of trying to get into recovery after this update using the Volume + plug in USB-C. (Update removed root/Magisk of course). It then wiped my entire device!!! No warning. No recovery screen. Just a message saying wiping device.

I immediately wiped it to put Lineage on it. :(

You need to make a copy of the flash all batch file and edit it and take out the line that reads "erase userdata" save the file. What this will do is make the factory image skip factory reset if you want to keep your files but wanna restore to fix or whatever.

So i flashed this and i also even tried flashing twrp and magisk like normal but after i would boot, most apps would not load. Im currently reverted to 8 to figure this out. If you could help me figure out what is wrong, would be appreciated.

hello buddy. Aaa you might be onto something. I am afraid I don't have my phone with me now. How do I check though if I have both parts of the bootloader unlocked?
Try fastboot oem device-info

But fyi, the razer phone has two parts to the bootloader. One is unlocked with
"Fastboot flashing unlock"
And the other is
"Fastboot flashing unlock_critical" i believe

Please can someone else confirm this please before I go ahead as I don't want to risk it?
