[RECOVERY][UNOFFICIAL] TWRP 3.5.0-0 for POCO M3 [citrus]

[enricoelo]

My Poco M3 was dead, charged but did not turn on.
I managed to get it into fastboot mode.
Mifalsh detected it but I could not flash it because it caused an error in deleting the device.
so I thought about installing TWRP Recovery
but at the first instruction he tells me:

C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot --disable-verity --disable-verification flash vbmeta vbmeta-citrus.img
target reported max download size of 804268032 bytes
sending 'vbmeta' (4 KB)...
OKAY [ 0.016s]
writing 'vbmeta'...
FAILED (remote: Flashing is not allowed in Lock State)
finished. total time: 0.016s

writing failed. How can I do now?

A thousand thanks

Hello,

View attachment 5179553
Team Win Recovery Project 3.x, or TWRP 3.x 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.

TheMalachite, may I ask you how did you compile the Poco M3 kernel? I tried


export ARCH=arm64 && export SUBARCH=arm64 export CROSS_COMPILE=/opt/aosp_prebuilts/aarch64-linux-android-4.9/bin/aarch64-linux-android- export DTC_EXT="/opt/google_misc/misc/linux-x86/dtc/dtc" make ARCH=arm64 CC=clang CLANG_TRIPLE=aarch64-linux-gnu- vendor/citrus-perf_defconfig make ARCH=arm64 CC=clang CLANG_TRIPLE=aarch64-linux-gnu- EXTRA_CFLAGS="-I $PWD/techpack/display/pll/ -I $PWD/techpack/camera/drivers/cam_sensor_module/cam_cci/ -I $PWD/techpack/camera/drivers/cam_req_mgr -DSDCARDFS_VERSION= -I $PWD/" -j$(nproc --all) 2>&1 | tee kernel.log

and unpacked/repacked boot.img with

unpackbootimg -i boot.img -o boot_img_unpacked mkbootimg --kernel "$SCRIPT_DIR/devices/$DEVICE/kernel/k/arch/arm64/boot/Image.gz" \ --ramdisk boot.img-ramdisk \ --dtb boot.img-dtb \ --cmdline "$(< boot.img-cmdline)" \ --base "$(< boot.img-base)" \ --kernel_offset "$(< boot.img-kernel_offset)" \ --ramdisk_offset "$(< boot.img-ramdisk_offset)" \ --tags_offset "$(< boot.img-tags_offset)" \ --dtb_offset "$(< boot.img-dtb_offset)" \ --os_version "$(< boot.img-os_version)" \ --os_patch_level "$(< boot.img-os_patch_level)" \ --pagesize "$(< boot.img-pagesize)" \ --header_version "$(< boot.img-header_version)" \ --hashtype "$(< boot.img-hashtype)" \ --board "$(< boot.img-board)" \ -o ../boot.img

but it won't boot. I tried unpacking/repacking the original boot.img with the original kernel just to see if I was repacking wrong but it worked, so my repack is working. I think the issue might be with dtbo inside the kernel, because my compiled kernel has 28mb vs 32mb from the original one. It's worth noting that the original one is for Android 11 and the one I compiled is for Android 10 but I doubt this is the problem because both are 4.19.x and usually one kernel works over 2 Android versions.

I also tried adding CONFIG_BUILD_ARM64_DT_OVERLAY=y to
vendor/citrus-perf_defconfig but it also won't boot.

PS: thank you for your TWRP image, please help on this, I'd be very very grateful!
