what steps r u trying to tell me?

classy kitchen can make it..unpack whole AP, mod it as you want then repacking
initial setup
1. BL from oreo BL_A920FXXU1ARL3
2.AP from pie AP_A920FXXU1BSF9
3.CP from oreo CP_A920FXXU1ARL3 or if you want the latest put the one from pie CP_A920FXXU1BSE7
4. CSC HOME oreo CSC_OMC_OXM_A920FOXM1ARL3
* make sure you untick autoreboot
* after flashing enter in recovery and factory delete data and cache
* reboot , make the initial setup , enable OEM and usb debugging
* install magisk 7.3.2 apk and patch the boot.img which you extracted before from AP from pie firmware
* after this step i make a moded AP tar only with :
boot.patched.img
recovery.img
system.img
vendor.img ....without the rest of :
meta-data, dqmdbg.img.ext4.lz4 , persist.img.ext4.lz4 ,userdata.img.ext4.lz4
* now i flashed with odin the files like :
BL from oreo
AP the modded one from pie already patched with magisk as i told you before
CP from oreo or pie ... as you wish
CSC HOME from oreo
MAKE SURE YOU UNTICK AUTOREBOOT IN ODIN
* after the pass message , enter in recovery mode and factory delete data and cache
* reboot and make the initial setup again checking the OEM unlock and USB debugging mode
* as a precaution put the software download update on off
* after making the setup for aditionall in magisk i installed root explorer 4.5 and i started to delete one by one the following :
= go to /system/vendor and modify the build.prop almost on the last of the page the following :
ro.security.vaultkeeper,feature=1 to
ro.security.vaultkeeper,feature=0 ....save and continue
= delete from /data/knox
= delete from /root/knox_changer
= delete from /system/info.extra
= delete from /system/tima_measurement_info
= delete from /system/bin/tima_dump_log
= delete from /system/bin/vaultkeeperd
= delete from /system/container
= delete from /system/hidden
= delete from /system/preload
= delete from /system/etc/tima
= delete from /system/etc/ASKSTS.xml
= delete from /system/etc/irremovable_list.txt
= delete from /system/etc/removable_preload.txt
= delete from /system/etc/sysconfig/samsungauthframework.xml
= delete from /system/etc/sysconfig/samsungpassapp.xml
= delete from /system/etc/sysconfig/samsungpushservice.xml
= delete from /system/etc/permissions/knoxsdk_edm.xml")
= delete from /system/etc/permissions/authfw.xml")
= delete from /system/etc/permissions/com.samsung.bbc.xml")
= delete from /system/framework/timakeystore.jar
= delete from /system/framework/knoxvpnuidtag.jar
= delete from /system/framework/knoxsdk.jar
= delete from /system/framework/knoxguard.jar
= delete from /system/lib64/libvkjni.so
= delete from /system/lib64/libvkmanager.so
= delete from /system/lib64/libvkservice.so
= delete from /data/knox
= delete from /data/preload
= Removing bloatware in /system/app the apk wich you do not use , in my case i will tell you what i delete as i was ussing my script from A6+ as a example for you to know wich one i deleted manually :
= all this apk i deleted manualy as far as i do not have TWRP for A920f .... you can decide by yourself what you want to keep or delete
=delete from/data/dalvick cache
= reboot the system
= if everything works great with the fingerprint , lock screen , samsung account ... then i go to recovery and format data in order to boot from zero and making the setup as a new phone , including setup for magisk for the root rights , installing magisk modules and so on ..
this was my work for a brand new phone A920F without a working TWRP but full functional root in order to delete the bloatware.
P.S any link where i can download classy kitchen ?
