Error when flashing hero2ltexx - Could not find 'META-INF/com/google/android/upda...'

I had some issues when trying to flash xposed and ended up formatting my data with TWRP.
After formatting data, I tried flashing root and xposed again. Xposed flashed fine, but root gave me an error. I thought it was because I hadn't gone through the system setup, so I went ahead and went through the setup and tried again but I'm getting the same error in TWRP.
Could not find 'META-INF/com/google/android/update-binary' in the zip file.
Error installing zip file '/external_sd/CF-Auto-Root-hero2lte'hero2ltexx-smg935f.zip'
What should I do?
Also, every time I boot in recovery now it asks me to swipe right as if it was the first time.
Thanks!

Bump. I haven't found a single solution to this on Google.

same problem here

You do not flash CF-Autoroot in TWRP. You extract the zip in Windows and Odin the tar file in order to obtain root.

My problem begins when installing "dm-verity and force encryption disabler". This are the errors it shows:
Could not mount /data and unable to find crypto footer
Failed to mound 'data' (Invalid argument)
Unable to recreate /data/media folder

The partitions seem to be corrupt.
Flash the cf auto root file via odin.
This will restore the stock recovery on your phone.
Then flash twrp via odin.
That's it, this should fix your problem.
You can then flash any rom you want.

Reverting to stock ROM

So, I had L31C432B381, and now have EliteROM properly installed as per developer instructions... I want to revert to stock B381 or better B389
I tried everything but i keep failing when flashing through twrp... system and data mounted YES... flashed stock SYSTEM.img, BOOT.img... went from f2fs to ext4... and back to f2fs...
I now understand that I cannot flash stock via twrp, else I get these errors
Installing zip file '/external_sd/update.zip'
Checking for MD5 file...
Skipping MD5 check: no MD5 file found
mountencrypt: failed to mount /data: No such file or directory
Removing unneeded files...
Removing empty directory...

E:unknown command [errno]
update_huawei_pkg_from_ota_zip: Update package from zip failed
Updater process ended with ERROR: 7
Error installing zip file 'external_sd/update.zip'
updating partition details...
...done
so now what should I do? I was told to rollback to MM then flash B389
If this is the only way, which MM build and how? dload + 3 buttons method?

Phone not accessable after trying to install Custom Rom

Hi,
so i've tried to root my phone and then to install a custom rom. the root went without any problem. After the root, i tried to install lineage OS 16.0 and followed this guide:
https://forum.xda-developers.com/redmi-note-7/development/rom-lineageos-16-0-t3923203
i downloaded the rom and gapps, put them on my root directory of my phone and then i wiped System,Cache ,Data, Internal Storage and Format Data. After wiping, the roms were gone, so i rebooted and transfered them again into the root directory. Then, i went onto installing (just like i did with magisk) but an error occurred saying:
E: String resource 'zip_compatible_err' not found. Using default value.
Zip Treble compatibility error!
Invalid zip file format!
Error installing zip file '....'
Updating partition details...
...done
Ok. So then, i tried to install another Custom Rom so i went for Oxygen OS, it actually did install but then i couldn't boot into it because it was telling me there was an 'Android System Error'. Ok, back in TWRP, i wiped everything and then i tried to install the Original ROM but i got the same error as above.
For now i tried to download the miFlasher tool but it only wants to download some driver and it literally takes forever.
Hope you can help me...

Those recoveries are old.. Use orange fox recovery 10.0-2 it will work and format data then install rom.

title?
@BlackGarnett
Thanks, that help me on a quick one!
@loseyourself
Also thank you for this advice, i'm new to rooting smartphones and install cfw since i was using iPhone for the past few years.
But now i got another new question: if i use orange fox recovery and i run a backup with it (i think there will be an option to do a backup), then i format all data and internal storage, can i still recover from the backup or will it be deleted?
thanks again!

Zips fail to install through twrp

HI!
So i have switch root following this guide ( https://team-xecuter.com/community/...ve-switch-on-the-same-sd-card-updated.132110/)
My issue is i don't seem to be able to install zips through twrp.
I get zip signature verification error, and then a message saying the zip is not installed.
My gapps installed just fine. but not shieldifier.zip, magisk, or joy con fixes.
i have tried re downloading the zips, clearing cache, as well as rebooting of course.
I am so lost.

Did you mount the relevant partition(s) before flashing ?
Also make sure yoiur flashable zips aren`t corrupt.
