You extracted the zip to a folder, then edited it, then compreseed that FOLDER. DONT COMPRESS THE FOLDER, compress the components of that folder to a zip file and flash it.

You don't have to compress the zip. Drag and drop the updater-script to a convenient folder. Edit it, and save. Then drag back the edited updater-script to the zip file and overwrite. (Make sure you keep a copy of original zip file).

Tell me the solution for red State. How to lock bootloader.
For red State means you have somehow not restored system properly
Happened because you didn't use TWRP as your recovery , unlock bootloader again flash twrp in recovery flash the firmware and it will be ok when you relock, If that's what were you doing already considering the problems with zip file of firmware it should be edited properly and not corrupted while you werr editing

    If you point the finger at me for messing up your device, I will laugh at you. Hard. A lot

    <Device will be formatted, so keep a backup >


    Requirements :
    Unofficially unlocked, Rooted Asus Zenfone Max Pro M2 with TWRP installed
    Windows / Linux

    Instructions :

    //relocking
    - Download the latest OTA firmware from Asus official website [turn off your VPN and head to asus.com > Products > Phones > Zenfone Max > Zenfone Max Pro (M2) > SUPPORT > Drivers and tools > Bios and Firmware ]
    - Extract the firmware zip and go to > META-INF > com > google > android
    - open updater-script with a note editor preferably notepad++
    - Remove all the lines (assert/abort lines) above the code
    Code:
    ui_print("Target: Android/sdm660_64/sdm660_64:X.X.X/XXXX/XX.20XX.XXXX.XXX-20XXXXXX:user/release-keys");

    You should be very carefull that you downloaded the correct(sku) firmware for your device, else doing this might brick your device
    - Save it, rezip the firmware and copy it to sdcard
    - Download and extract "Relock" zip
    - Copy stockrecovery.img to sdcard
    - Go to "adb + asus drivers" folder and install ADB and necessary drivers
    - Flash TWRP, if you are on any other recovery
    - Boot into recovery > install > flash the firmware zip
    - Reboot to recovery, if custom recovery comes again, install > image file > stockrecovery.img > as recovery > flash > Reboot to bootloader
    - Go to "relock" folder, open an elevated command prompt (admin) and enter :

    Code:
    fastboot devices
    (device should be listed)
    now execute relock_bl.cmd (windows) or ./relock.sh (linux)

    Device will boot up without unlocked bootloader warning.
    To check if bootloader is locked, go to fastboot and enter :
    Code:
    fastboot oem device-info
    Thats it, bootloader relocked!

    relock.sh for linux system. Just put it in relock folder and Rename relock.txt to relock.sh then run(sudo ./relock.sh) through the terminal(sudo chmod -R +777 relock.sh ===> run this before running relock.sh). Say thanks if you want.

    Somebody reply this thread..

    Wipe, restore the backup, and flash the stock recovery. But doing this is kinda stupid, as your data will be wiped anyways and have to do a hell lot of updating (if the backup is old) after relock. Also, if your back up was modified in someway, beware of the Red state.

    I've bought this phone 3 months ago... Haven't done anything with it, just going on with official updates. Had slept one night with earphones on and the battery discharged totally... Now getting this warning whenever I restart my phone... What could have gone wrong?

    Unlock bootloader flash stock ROM and relock bootloader. If you don't have any idea about this, take it to service centre
