Mine got up to 26%
Phone screen show: Write Data > 26% Time: xxxxxxx
After that, it took several minutes to progress to 27%, then it is taking a long time again

    Remember, my mtkfastboot.exe error out on phone 1st boot, so the mtkfastboot.exe CMD window stopped.
    Then, if I run mtkfastboot.exe again (in separate CMD window) and immediately run "fastboot reboot fastboot", phone will reboot into "=> FASTBOOT mode..."

          jessiesmith Once phone is in "=> FASTBOOT mode..." then you should run fastboot reboot fastboot once the phone is in fastbootd like in the picture you shared then in a new CMD window (nothing to do with mtkfastboot.exe) run the command fastboot flash super /path/to/super

              Got it flashed with one of the ROMs that have Waze.
              When I open Waze, top screen just show "preparing navigation voice 0%", and stuck there. The map would not load.
              I am somewhat new to this, maybe i need to post the question on other thread.
              Also, I read there's a kosher app store, is it really possible to install the app store onto the phone, and then install other apps from the store directly intead of downloading the apk and manually loading it.

                jessiesmith Not sure where you read that there is a kosher app store, but there isn't (last I checked).

                Also this kosher rom blocks APK Installation so you wont be able to install any apps.

                    On Waze app, I could not get a GPS fix, error message "No GPS Reception".
                    Initially, I forgot to set the location on, so I did:
                    phone Menu -> Settings -> 5. Phone Settings -> 5. Location -> Set to On.

                    Restarted phone and restarted Waze several times, still can't get GPS working. I am outside with clear view of sky. No SIM card, but that shouldn't affect it, maybe just a slower GPS fix. On Wifi.

                    I read on forum posts people say to uninstall and reinstall it. But since this kosher ROM blocks APK installation, so I guess I couldn't do that.

                    Anyone have any ideas?

                        jessiesmith if I recall correctly, adb still works in the kosher rom (correct me if not). So dial *#*#33284#*#* to enable, then run adb shell pm clear com.waze, and let me know if that fixes it.

                        Alternatively, dial *#*#217703#*#*, go to MTK Non Framework LBS > Modify app location permission > permissions > use mouse to access search bar on top > search waze, open waze, click storage > clear data

                          the "Fast Method (first time)" does not work. It bricked the phone, after reboot, phone show "Secure Boot Failure! dm-verity corruptiopn"

                          Any way to rescue this?

                          Phone software version KEFH.

                          Details steps I took:
                          Open CMD, run mtkfastboot.exe
                          With phone OFF, connect phone to PC.
                          Phone screen will show "=> FASTBOOT mode..."

                          Open another CMD, run:

                          fastboot flashing unlock
fastboot flash recovery recovery2.img

                          I see your post is missing:
                          fastboot flashing unlock, I need to run this otherwise it won't let you flash recovery2.img

                          Then I ran
                          fastboot reboot recovery

                          Phone screen shows "Android Fastboot", with several options. On bottom of screen, I see a lot of error messages about "Invalid argument", "failed to format /cashe", etc. I ignored it b/c yesterday on another phone, I was able to continue even with those messages.

                          I then ran

                          adb push super.bin /dev/block/by-name/super

                          I used a different image name, but I don't think filename matters as long as the image is correct.
                          After that, the fastboot CMD window could not find the device, so I could not run fastboot reboot.
                          So on the phone, I clicked "Reboot system now".

                          After reboot, it show me the bricked screen "Secure Boot Failure! dm-verity corruptiopn"
                          [Login to see the link]

                          if I use CMD, run mtkfastboot.exe, the phone can still go to ""=> FASTBOOT mode..."
                          On another CMD, I did fastboot devices, and it show the device.
                          I then did:

                          fastboot flash recovery recovery2.img
fastboot reboot recovery

                          It will take me back to the bricked screen "Secure Boot Failure! dm-verity corruptiopn"
                          [Login to see the link]

                          I then removed battery, and put back in.
                          CMD run mtkfastboot.exe, the phone into PC, phone screen shows ""=> FASTBOOT mode..."
                          On another CMD, ran:
                          fastboot flashing unlock
                          On phone, Press "volume +" key to unlock.

                          Keep running these commands:

                          fastboot flash --disable-verity --disable-verification vbmeta vbmeta.bin
fastboot flash --disable-verity --disable-verification vbmeta_system vbmeta_system.bin
fastboot flash --disable-verity --disable-verification vbmeta_vendor vbmeta_vendor.bin
fastboot flash boot boot.bin
fastboot reboot fastboot

                          Rebooted, got the bricked screen, and phone kept rebooting a few times, I then disconnected USB cable. Now the phone is showing the Android Fastboot Menu:
                          [Login to see the link]
                          Fastboot cannot access the device.
                          On phone, I clicked shutdown, it just show me a bunch of error messages and won't shutdown.
                          I then removed battery to force shut off, then put battery back in.

                          CMD run mtkfastboot.exe, plug the phone into PC, phone screen shows ""=> FASTBOOT mode..."
                          On another CMD, ran:
                          fastboot flash super super.bin
                          Hopefully this will unbrick it.

                          Is there an original factory image somewhere for me to download? Is it the same steps to flash the factory image as the kosher images?

                              jessiesmith I see your post is missing:
                              fastboot flashing unlock, I need to run this otherwise it won't let you flash recovery2.img

                              My post is not missing anything. Please read it carefully. It is not for people with locked bootloaders.

                              jessiesmith Then I ran
                              fastboot reboot recovery

                              Phone screen shows "Android Fastboot", with several options.

                              I am assuming this is a typo or you don't remember correctly, you probably mean it shows "Android Recovery".

                              jessiesmith On bottom of screen, I see a lot of error messages about "Invalid argument", "failed to format /cashe", etc. I ignored it b/c yesterday on another phone, I was able to continue even with those messages.

                              Correct, don't worry about those, they are recovery logs, not really errors (this is the other reason I am assuming you are in recovery and not Android Fastboot; Because Fastboot doesn't show those logs).

                              jessiesmith I then ran
                              adb push super.bin /dev/block/by-name/super
                              I used a different image name, but I don't think filename matters as long as the image is correct.

                              yes, the file path
                              /dev/block/by-name/super is very important, but not the file path to the super on your computer is okay for any valid super img.

                              jessiesmith I then ran
                              adb push super.bin /dev/block/by-name/super

                              You seem to have missed an important command (see my post you replied to - you need the chmod command).

                              jessiesmith After reboot, it show me the bricked screen "Secure Boot Failure! dm-verity corruptiopn"
                              [Login to see the link]

                              It doesn't say your phone can't boot. It says that software cannot be trusted (as authentic factory images).

                              You have the option to press the power button to continue booting, or else it will turn off.

                              From my experience, sometimes I need to hold the power button for about a second, but not two long. Or try holding for 1 sec, let go, and hold for another sec. Then let go and wait, maybe it will boot up.

                              jessiesmith Keep running these commands:
                              fastboot flash --disable-verity --disable-verification vbmeta vbmeta.bin
                              fastboot flash --disable-verity --disable-verification vbmeta_system vbmeta_system.bin
                              fastboot flash --disable-verity --disable-verification vbmeta_vendor vbmeta_vendor.bin
                              fastboot flash boot boot.bin
                              fastboot reboot fastboot

                              Good, those are important.

                              jessiesmith Fastboot cannot access the device.

                              So probably you need to install fastboot drivers, check the link in [Login to see the link] original post. I repeat again that if you read my post, it explains that it is for updating roms, not installing for first time.

                              jessiesmith On phone, I clicked shutdown, it just show me a bunch of error messages and won't shutdown.

                              If I guess correctly it will shut down, but you need to be patient (and wait a few more seconds, then it will shut down).

                              jessiesmith CMD run mtkfastboot.exe, plug the phone into PC, phone screen shows ""=> FASTBOOT mode..."
                              On another CMD, ran:
                              fastboot flash super super.bin
                              Hopefully this will unbrick it.

                              Good luck!
