[afaneh92]

Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

 * Your warranty is now void.
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or your getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.

Note1: You need a custom permissive kernel to boot with R/W vendor.
Note2: If you got bootloop on Samsung logo, reboot to TWRP and wipe metadata from Advanced Wipe section.

Hi, thank you for twrp. Can this make system R/W ? I need to modify some files in system image. Thanks

Not yet, still need a lot of work

Can S22 with 8GEN1 use this TWRP ？

 

[afaneh92]

Can S22 with 8GEN1 use this TWRP ？

Check OP there is supported list, also you know 8gen1 is snapdragon and the title says exynos and you still asking if it works?
Check the othe snapdragon thread.

Step 4 fails for me because of Knox Guard. Custom binaries blocked.

There is no way around this right?

 

[majo11x1]

Hi, noob question here...
Can I update firmware and retain root and TWRP without losing data? If yes - how to do it?

Worked perfectly with given guide!

1. TWRP recovery running
2. Could flash custom kernel from afaneh92
3. Also I downloaded Kernel tree and used build_menu to compile the same kernel with arch/arm64/configs/afaneh_r0s_defconfig
4. Could flash custom kernel self compiled as mentioned from (3.)



Next step was to adjust the defconfig from afaneh92 with some other features, but everytime I stuck in bootloop if I try. My approach was the following:
1. Load env variables from build_menu
2. make menuconfig load afaneh_r0s_defconfig
3. activate features from =n to =y (i.e. CONFIG_IP_VS=y)
4. copy newly created .config settings into afaneh_r0s_defconfig
5. start build_menu -> build kernel -> r0s
6. make flashable zip
7. boot into TWRP recovery and install custom kernel
8. Result: stuck in bootloop
my config still has CONFIG_SECURITY_ALWAYS_PERMISSIVE=y

Is this the right approach to add features to my kernel, or I am totally wrong with this? Here are some features I need for my kernel:

BLK_CGROUP	DUMMY
BLK_DEV_THROTTLING	EXT3_FS_POSIX_ACL
BRIDGE	IP_VS
BRIDGE_NETFILTER	IP_VS_NFCT
VLAN_8021Q	IP_VS_PROTO_TCP
BRIDGE_VLAN_FILTERING	IP_VS_PROTO_UDP
BTRFS_FS	IP_VS_RR
BTRFS_FS_POSIX_ACL	IPC_NS
CFQ_GROUP_IOSCHED	NET_L3_MASTER_DEV
HUGETLBFS	IPVLAN
CGROUP_HUGETLB	MACVLAN
CGROUP_NET_PRIO	NETFILTER_XT_MATCH_ADDRTYPE
CGROUP_PERF	NETFILTER_XT_MATCH_IPVS
DM_THIN_PROVISIONING	SECURITY_APPARMOR
VXLAN	USER_NS

you can simply edit afaneh_r0s_defconfig

 

[lowowly]

I did. I.e. I changed

# CONFIG_IP_VS is not set
to
CONFIG_IP_VS=y

then compiled, flashed and tried to boot into system but stuck in bootloop.

I started to create the config with menuconfig because sometimes activating some of the CONFIG_ features additionally dependencies come in place or are not even available to activate.

Like activating CONFIG_IP_VS with menuconfig result in following:
CONFIG_IP_VS=y
# CONFIG_IP_VS_IPV6 is not set
# CONFIG_IP_VS_DEBUG is not set
CONFIG_IP_VS_TAB_BITS=12

Or if you want to use CONFIG_BRIDGE_VLAN_FILTERING you first need to activate CONFIG_VLAN_8021Q because of the dependencie.

So I thought doing with menuconfig is the "saver" solution. But anyway, got the same problem.

Anyway this is twrp thread, and I don't support kernel edit, mine is stock permissive

 

[lowowly]

Thank you so far. Then I need some help in kernel edit. I start a new topic in questions section.

I'm getting bootloops on Android 13 BWA2, ADB doesn't work either. There's no possibility to install ROMs since the data partition is wiped when you flash TWRP and you can't copy files from windows to the device because it's not recognized.

You flashed the kernel!

 

[neo2k12]

You flashed the kernel!

How am I supposed to flash the kernel if I can't get the zip file on my phone? Can you provide a tar file to be flashable in Download mode?

 

[robbo1947]

Will your TWRP be compatible with the new S23 series?
