Cannot update from cyanogen recovery to twrp recovert

Hello,
I am trying to update from the old cyanogen recovery to the TWRP recovery in this post: https://forum.xda-developers.com/showthread.php?t=3557606
I have enable to write the cyanogen recovery in the developer options.
I have rebooted into flashboot and executed:
----
[email protected]:/tmp/xperia/TWRP# adb reboot bootloader
[email protected]:/tmp/xperia/TWRP# fastboot flash recovery twrp-3.1.1-0-z3c_V02.img
target didn't report max-download-size
sending 'recovery' (14296 KB)...
OKAY [ 0.572s]
writing 'recovery'...
OKAY [ 0.930s]
finished. total time: 1.502s
[email protected]:/tmp/xperia/TWRP# fastboot reboot
rebooting...
----
Unfortunately the system boots in the cyanogen recovery anyhow.
does anyone knows what am I doing wrong ?
Many thanks in advance

There's an app called NDR Utils that lets you choose which recovery to boot to, but I don't know of a clean link where you can get it.
I got it with Nut's Dual Recovery:
http://nut.xperia-files.com/path/XZDualRecovery/XZDualRecovery_2.8.26

I mean you have to unlock your bootloader with:
Code:
fastboot -i 0x0fce oem unlock 0xhex_unlock_key
(see here)
also you have to erase the old recovery with:
Code:
fastboot erase recovery
(claimed in this guide here)
Edit: I forgot you used a CyanogenMod Recovery, which is stored in FOTAkernel,
so you have to use also :
Code:
fastboot erase boot
fastboot erase FOTAKernel
I did read it here
Hope that does help you

Thanks a lot !

Unable to unlock/flash recovery

I am trying to unlock the bootloader and flash TWRP for the first time. I followed the steps from here: https://wiki.lineageos.org/devices/s2/install
I turned on the unlock option in settings and unlocked via fastboot, rebooted it manually (it didn't reboot), and then tried to flash:
Code:
$ ./fastboot oem unlock-go
OKAY [ 0.007s]
Finished. Total time: 0.007s
$ ./fastboot flash recovery twrp-3.3.1-0-s2.img

$ ./fastboot reboot recovery

However, I got into the stock recovery page instead of TWRP. You can see above that the flash failed before I rebooted, but succeeded after that. Interesting observations:
- The above webpage indicates that the device should reset when I reboot, but it didn't, which means the unlock didn't work.
- When I went back to bootloader, the first attempt to flash failed, but when I ran another unlock it worked though apparently it did nothing.
Am I missing a step? I am using fastboot version 29.0.6-6198805 on Mac OS Mojave 10.14.6.

Don't reboot to recovery via a command after flashing it.
Try rebooting using buttons, vol-up + power.

Thank you! That got me into TWRP with a dialog titled "Unmodified System Partition" with a slider to allow modifications. I am googling to see what this dialogue is about and how to get TWRP to permanently get installed.

That's normal. Just enable modifications and that's it.

OK, I don't remember seeing it before (I haven't flashed in at least a couple of years). I ran `adb reboot recovery` and it did go back into TWRP, so I am assuming that it did get persisted. For some reason "Never show this screen..." option didn't work, which is fine, but does it indicate that something is still readonly?

I don't think so.
You're good to proceed.

I was able to sideload the ROM and opengapps nano and it is booting up for the first time. I skipped the optional step to install root (AddonSU), I guess I can do it later too if I feel the need to get root. Thanks a lot for your quick help.

No problem.
If you want to root it, do it with Magisk.
Nowadays, LineageOS team recommend it.

Question Can't reboot phone unless I manually wipe dalvik cache. (TWRP+Magisk 24.102)

I have a problem that I can't reboot my phone unless I manually wipe dalvik and ART cache between reboots. Any idea why? TWRP and rooted using Magisk 24102.
I am running MIUI EEA 12.5.11 Stable (RKAEUXM). Downgraded from Xiaomi.EU due to the bugs.
booted into TWRP via fastboot. Mi11Ultra(Pro)-twrp3.5.1-recovery-21.5.9-decrypted.img
installed TWRP recovery via Onekey inject TWRP.
wipe dalvik cache
dd if=/dev/block/bootdevice/by-name/boot of=/sdcard/TWRP_boot.img to extract boot image with TWRP.
reboot
Patch Magisk 24102 onto the TWRP_boot.img and reboot into recovery.
Install Magisk_patched_TWRP_boot.img onto both boot slots.
wipe dalvik cache
Everything is working OK until I reboot. If I try to reboot, phone freezes and goes straight into recovery. Wiping Dalvik cache lets me boot into the phone.
I tried following the guide here, but if I Install Recovery Ramdisk onto the Mi11Ultra(Pro)-twrp3.5.1-recovery-21.5.9-decrypted.img, once I reboot into recovery, touchscreen does NOT work.
If I try to install Onekey inject TWRP instead of Install Recovery Ramdisk and then try to fastboot install the Magisk patched boots, i get the FAILED (remote: '(Boot_a_a) No such partition') errors:

Questions:​
Any idea why I need to wipe dalvik cache to be able to boot into my phone?
Any idea why when trying to install TWRP via Recovery Ramdisk my touchscreen stops working?

U can try official guide by magisk https://topjohnwu.github.io/Magisk/install.html

Unable to flash any recovery. Please help

I am on 12.5.4.0 stock ROM. I am unable to overwrite the stock MIUI recovery. I always get the error message:
FAILED (Status read failed (Too many links))
The recovery image that i am using is a lineage OS 18.1 recovery image that i obtained from a Telegram group on a new lineage 18.1 ROM. I also tried a TWRP image by wzsx, with the same result.
I also tried disabling vbmeta with the command:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta\vbmeta_vd171--V12.5.3.0.RJOMIXM.img
Rewriting vbmeta struct at offset: 0
Sending 'vbmeta' (4 KB) OKAY [ 0.016s]
Writing 'vbmeta' OKAY [ 0.000s]
Finished. Total time: 0.016s
But after reboot it goes back to MIUI recovery.
Previously i had flashed crDroid ROM with an SHRP recovery. I remember getting the same "Too many links" error that time too, but i have forgotten how i managed to flash SHRP that time.
I tried using SP FLash Tool , but here too i get an error message " Invalid scatter file name" or something like that for the scatter file in the 12.5.4.0 stock ROM. Then i tried MTK tool to create a scatter file for my Redmi Note 9 but this time i get an error saying it is unabke to read the ROM storage format. Can anyone please help?

Do:
fastboot flash vbmeta vbmeta_vd171--V12.5.3.0.RJOMIXM.img
Is same to do:
fastboot --disable-verity --disable-verification flash vbmeta original_stock_vbmeta.img

It seens a problem with typing.
Did you try to use quotes?
Like
fastboot flash recovery "here is the place/of/image.img"

Are you sure are not booting into MIUI after flashing? because MIUI installs back the default recovery.

Exactly.
If you want to use custom recovery but without root/magisk, you need to flash my patched boot image.
This patched boot image does NOT install back the default recovery and does NOT install root/magisk.

Thanks to everybody who replied. But i am using the command "fastboot reboot recovery" after flashing the recovery. But you are right, i did realise that if you just reboot to a stock ROM it reinstalls the stock recovery. Mea Culpa. But i wish this was explained someplace like a general explainer to a newbie.
Anyway, i downloaded the "Platform tools SDK" and used that fastboot and it now installs SHRP and Lineaage OS 18.1 recovery. But TWRP is still a problem. But at least i can install any custom ROM that i want. And yes, thanks VD171, i won't forget to use your patched boot image from now on.

You are welcome, my friend.
Enjoy
Sadly, no one says that to you.
But, if you want to enter in recovery, just type "fastboot reboot" and hold the Vol Up button.

remove TWRP and install Linageos recovery error.

I have a pixel 5, i installed linageos recovery and lineageos rom
however when i tried TWRP it now is frozen on splashscreen for recovery project 3.7.0_11.0
i tried flashing back lineage, it says it worked but when i restart recovery the same splash screen is there.
