I need help to remove the signature check from the stock recovery of my Ulefone Armor 11 running Android 10.

I remember such recovery on my old Huawei.

TIA

signature check? can you explain what you mean by this?
if you're referring to dm_verity then see method 3 (empty vbmeta) @ https://www.hovatek.com/forum/thread-32719.html

No II'm not referring to dm_veritym I already bypassed it with an empty vbmeta.
My problem is that I cannot run the OTA update because it patch the boot image that is changed because of Magism, and for some reason even reflashing the original stock boot.img and original vbmeta.img doesn't let the update run.
So I modded the update.zip to install a whole image instead of just apply a patch to the existing one. Infortunately when I reboot in recovery and I choose adb sideload the update doesn't start because my update.zip os not signed with the Ulefone key.

For Huawei were created modded recovery where this check was removed to let rebrand the phone.

Because there is no TWRP for my Ulefone Armor 11 running Android 10 I would like to mod the original recovery only by removing this signature check. I tried to unpack it, but I didn't find where the Key is stored.

flash back full stock firmware then retry updating directly from system updates in settings

Flashing back the whole firmware with the software provided by Ulefone will also erase all of my data and settings, that's why I'm looking for an alternative solution while waiting for TWRP 3.5.

TWRP would be better suited for this that trying to Mod stock recovery

If I remove otacerts.zip from the recovery will it bypass the check?

Or I should create a private and public key and chang it in the recovery?

TWRP porter create only use Twrp 3.4 that does not work well with Android 10

I unpack and repack usifn carli image kitchen and removed otacerts.zip, but I don't understand why the original recovery is 40 Mbyte big and the new one 17.8 Mbyte.

Edit

The original recovery is full of 00 00 00 block at the end

Removing otacerts from recovery doesn't work.

It claim that it cannot find otacerts.zip
