Sony Xperia Z2 wont boot into recovery

Good day,
I had to rooted in front of my Sony Xperia Z2 so I wanted to install TWRP which worked the way it looked, but I can not boot into recovery mode that should light up the status LED should not light up.
Sorry for my bad english.

i assume you tried to flash it to Recovery partition ?
how did you flash the recovery ?

This is what you are doing wrong
actually in most Sony devices , you have to flash a kernel that contains the recovery in it.
When you unlock the bootloader, Sony's stock kernel freezes the recovery partition,thus you will need a custom kernel to be able to access recovery again
modern sony devices has custom kernels that has twrp built to them

download this and unzip it
you will find a boot.img file or a file with the name of the kernel.img
Take that file into the fastboot path
rename it to boot.img
put the phone into fastboot
type
fastboot flash boot boot.img
this should get you the custom kernel with twrp included , you can then update the twrp accordingly

Your device MUST have an unlockable bootloader.
Your device MUST be Project Treble compatible. That means your device meets one of the following criteria:
Your device LAUNCHED with Android 8.0 Oreo or a newer version (eg. Android 8.1 Oreo) AND is Google Play certified. (If you rooted your device/flashed another custom ROM and somehow ended up with your device being listed as uncertified in Google Play, then don’t worry. We’re only concerned about the status of the device as it was shipped.)
Your device UPGRADED to Android 8.0 Oreo or a newer version AND was made Project Treble compatible by the manufacturer. See this article for a list of such devices.
Your device does not meet either of the above criteria but DOES have access to an unofficial way to be made Treble compatible. Again, refer to this article for a list of such devices.
Your device is free of any heavy modifications such as the Xposed Framework, SuperSU, or Magisk. You can re-install these afterward, but please be sure you are using the stock boot/ramdisk before proceeding.

thats complete bs
your device must be launched with android 10 or newer to be able to have dynamic partitions.
google play certification has nothing to do with it.
and if you flash product partition you might get away without reinstalling magisk or xposed

can anyone shed light on whether or the super partition is shared between the slots? in other words, if I flash a boot image to super partition in twrp, will it flash only to that slot's super (slot B in my case is messed up) or will it flash to both slots? I am only trying to flash to slot B super partition in hopes of restoring /system_ext, /product, and /odm. any help is greatly appreciated

ok the reason I ask is I am given the option to flash my backup boot image to super in twrp flash image screen, that's why I asked, and since twrp is reporting that I'm missing system_ext, product, and odm, that flashing to super would fix that, a long shot but I'm desperate.
so to be clear is it shared between slots or does each slot have it's own super? (or the partitions found in it)

Phone bricked when installing twrp

Hello guys my phone is stuck in a bootloop because I tried to install twrp from fastboot.
I unlocked bootloader and started Fastboot.
Then I connected my phone to my mac via USB.
Then I ran this commands:
./fastboot flash recovery recovery.img
./fastboot flash vbmeta vbmeta.img
(The mistake I think I made was that I flashed recovery before vbmeta).
Then I restarted my phone and I could not get into android or fastboot.
Please I need help.
This is the tutorial which I used.
Thanks in advance.

Apart from the wrong order of flash commands, it should be noted that
Code:
fastbbot flash vbmeta vbmeta.img
absolute is meaningless: stupidly overwriting an existing vbmeta.img MUST brick any Android device.
The correct Fastboot command should have been
Code:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
what makes the necessary change in supplied vbmeta.img before it gets flashed.
My recommendation: Try to re-flash phone's Stock ROM.

I will try to Flash the stock ROM using SP Flash Tool.
I won't try to install twrp anymore if this stock ROM flashing works.
I'll kill my dreams of rooting my phone and installing android 12.
(I hope it works because am not getting a new phone until next 3 years)

[Solved] VBmeta Flashing and Disable Verity Verification Command Problem

Thought to share with you guys, as many of people like me face problem while disabling the verification while flashing VBMETA.img.
Most of the time the below command does not work and causes bootloop, when Installing Custom recovery.
So i searched a lot and found the perfect solution which is working 100% and tested personally.
Code:
fastboot flash --disable-verity --disable-verification vbmeta vbmeta.img
The errors we receive while flashing this command is due to SDK platform tools version
30.0.5 version is working fine and i have attached it along with this post so nobody else will go through the searching i have went.
This is the whole sole purpose of this thread.

Can you tell me how to do it with Heimdall on Linux? Using this file attached below, but i also ask you, is this file i posted only special for my device? The guy who told me to flash this told me to use odin and place the file on ap slot, just like how i previously flashed the custom recovery.

hi ,may i ask which first, do i need to flash the vbmeta before custom rom?. thanks much appreciated

Recovery, VBMETA (if required), Rom, (Microg if you want, i never recommend), and magisk root if you wanna root.

Are you sure your custom recovery works for your phone? You need to flash vbmeta to get rid of the AVB verification steps, otherwise you end up with a non-booting system because of the differences in keys built in to the hardware, the system partition and the boot partition.

Can anyone tell me, i am having poco m2 Xiaomi , what's the use of vbmeta and is it compulsory to flash vbmeta while flashing custom rom or recovery.

Just used the latest adb tools on cmd admin. Fixed

If there is TWRP for your version of Android, flash Magisk.zip from TWRP.

who told you to flash vbmeta.img?
You should flash patched_boot.img in fastbootd

You need to edit out vbmeta.img / vbmeta_system.img to actually disable verification. Change the byte at offset 123 from 0x00 to 0x03.
Another way is to use the following command when flashing vbmeta. You may need to use a relatively newer version of fastboot binary to get it work.
Code:
fastboot flash --disable-verity --disable-verification vbmeta vbmeta.img

Which Magisk version did you use? From what I can tell any official Magisk version should work.
I haven't really tested the recent builds of vvb2060's Alpha or huskydg's Delta... so if you're using these versions I can't really help you much...
Additionally, you need to check which slot you are now, and through fastbootd check which slot actually has system, vendor and such. Normally the super partition only has enough size for one slot. You may have entered a wrong slot that doesn't have usable system.
