are you on android oreo 8.1? if not download cheryl-p-release-7083-user-full.zip for android 9.0 (link added post #19)

flash the boot.img into both slots. if you still can't boot android, flash the whole ROM with dirty_flash_android_only.bat

 

[razerphone1]

i was in android 7 before try to install new rom.i downloaded the cheryl-p-release-7083-user-full.zip
here is what i see inside the zip folder

what next now brother ? i must flash the boot.img ? where and how ?

 

[alecxs]

if you were on Android 7 you need boot.img for Android 7. do you want to keep Android 7? if not, flash the whole ROM to upgrade Android 9

 

[razerphone1]

i want new android brother i would like android 9. i need download upgrade 7 to 9 ?

flash whole ROM+firmware from flash_all.bat first

 

[razerphone1]

i did double click on it flash_all.bat
the window showed this
C:\Users\Main User\Desktop\cheryl-p-release-7083-user-full\cheryl-p-release-7083>set fastboot_cmd=fastboot

C:\Users\Main User\Desktop\cheryl-p-release-7083-user-full\cheryl-p-release-7083>fastboot getvar product 2>temp.txt

the phone starting working and done the instalisation. its updating from wifi now. i see problems with mobile sim signal and cant change language too. what next?

 

[alecxs]

You have flashed "Razer Global Images for Razer Phone 1" but no SIM?

maybe "Carrier Specific Images for 3 (CKH) for Razer Phone 1" is the right one.

 

[razerphone1]

i can use sim options but i have not signal or mobile data

 

[alecxs]

I think you somehow lost your baseband (efs partition) during the installation of ROM. try Carrier Specific Images for 3 (CKH) for Razer Phone 1 hopefully it will fix.

 

[alecxs]

or maybe you didn't even flash all partitions? did you see any error messages during flash_all.bat?

according to this thread one must unlock critical partitions first

[razerphone1]

i will try soon the Carrier Specific Images for 3 (CKH) for Razer Phone 1 . i have not errors and the phone working very better from andoind 7. wifi is better too. the only problem is the language for me but i will do this flash to help others about this mobile.its very usefull the file and you just click it ,the phone erasing before install everything.i think have recovery twrp too

 

[alecxs]

mobile data is working now? can you see baseband version in 'about phone' section? no need to try other ROM then..

you managed to install TWRP + Magisk?

 

[razerphone1]

mobile data and languages working. i did not install twrp + magisk. i thought twrp was in the flash_all.bat
i downloaded the cheryl-ckh-p-release-7087-user-full i am thinking to test this rom too. whats the difference ?
i would like a rom just for gaming. i dont like backround apps like google and other phone apps

 

[alecxs]

no, now you can start from scratch and install TWRP. you need the boot.img, Magisk.apk, twrp-installer.zip and the TWRP.img. should I guide you?

 

[razerphone1]

yes please.i would like to make a backup to default too. btw i dont know what twrp version i need

 

[alecxs]

prerequisites: first, make sure bootloader is unlocked. if not unlocked, it leaves you no choice to factory reset again. enable OEM unlocking in developer options, reboot into bootloader and unlock from fastboot.

1) next download latest TWRP. you have boot.img of cheryl-p-release-7083 therefore it's safe to flash twrp into both slots. This is easier than the official instructions. you can just restore boot.img once in TWRP.

fastboot devices
fastboot flash boot_a twrp-3.7.0_9-0-cheryl.img
fastboot flash boot_b twrp-3.7.0_9-0-cheryl.img

reboot the phone. it has no choice other than boot into TWRP. if TWRP doesn't work, try again with older version.

2) once in TWRP restore the boot.img of cheryl-p-release-7083 from adb. do this while in TWRP

adb devices
adb push boot.img /tmp
adb shell
# dd if=/tmp/boot.img of=/dev/block/bootdevice/by-name/boot_a
# dd if=/tmp/boot.img of=/dev/block/bootdevice/by-name/boot_b
exit

3) now the boot.img is restored, you can proceed installing TWRP and Magisk (in this order)

a) copy files to phone (note that apk is renamed to zip)

adb push twrp-installer-3.7.0_9-0-cheryl.zip /tmp
adb push Magisk-v25.2.apk /tmp/Magisk-v25.2.zip

b) prepare Magisk settings

adb shell
# echo 'KEEPVERITY=false' > /cache/.magisk
# echo 'KEEPFORCEENCRYPT=true' >> /cache/.magisk
# echo 'PATCHVBMETAFLAG=true' >> /cache/.magisk
# exit

c) install TWRP from menu - install - navigate to /tmp - twrp-installer-3.7.0_9-0-cheryl.zip - swipe to confirm

d) install Magisk from menu - install - navigate to /tmp - Magisk-v25.2.zip - swipe to confirm

e) finally, just in case something did go wrong, get the recovery.log

adb pull /tmp/recovery.log

you can now reboot.

4) when phone booted successfully, install Magisk-v25.2.apk to get rooted. done.

(you can reboot into TWRP recovery from Magisk reboot menu any time)
