Razer phone Android 9.0 Pie cheryl-P-Magisk-twrp-boot

[patient81]

What are the guaranteed steps to avoid losing WiFi when flashing this? Tried to flash this after the latest November security update with clean flash and lost WiFi. Think it has something to do with having a pattern or lock code set during boot.

Glad I'm not the only one. I had to go back to 8.1 stock then update to the latest 9 to get wi-fi back. Hope the OP sees this and can help us with an updated boot img.

How do I do an OTA update on this?

We have a security patch update for November just released, with some bug fixes.

Can you Upload the Stock boot.img for Android 9.0 cheryl-p

This would be great.

It would also be very helpful if Razer provided this update as a factory image on their developer site.

Been thinking about this a bit more. Surely any of us could temp boot (not flash) twrp then backup the boot.img from the inactive slot?

Might try this myself.

Looks like Razer finally updated their factory images portal! December's image is up!

This would be great.

Is this still being maintained, or does anyone know how I could rebuild the boot img myself?

I'm not the mantainer or very knowledgeable on this, but the stock Pie image was released and I guess that could be useful for extracting an updated boot.img...

Correct commands

I don't want to mess this up, I'm a little rusty rooting phones. So from a booted up phone running android 9 with an unlocked bootloader.

commands:
adb reboot bootloader (this is the part I'm unsure of)
fastboot flash boot_a cheryl-P-Magisk-twrp-boot.img
fastboot flash boot_b cheryl-P-Magisk-twrp-boot.img
fastboot reboot

I'm also double checking that this will not wipe my device.

Thanks Mucho!

I've got the same problem. Every time I flash the img I lose wifi. Any updates?

Adb reboot bootloader will reboot into download mode, where you are supposed to issue the fastboot commands, so that's ok.

When in doubt, always back up your data. There's no such thing as a worthless backup.

Also be sure to have your drivers installed. Do adb devices and see your device pop up in the output. The same with fastboot devices.

Thanks I managed to move forward but now I've dug myself a huge hole. https://forum.xda-developers.com/razer-phone/help/help-bricked-stuck-android-logo-boot-t4108879
The point of my trying to get TWRP/root running was to backup my phone
