Hi!
So after doing a software update (the one that pops up in the notification drawer), my phone won't boot. I could load up or get the classic "Secure booting error", but that was it. Now, I can't even do that. If I hold down volume up and volume down while connecting the USB cable, the phone will go into download mode and reboot after a second or two to the "Secure booting error" which will start in turn reboot after a few seconds to the same screen causing a loop.
My Lg optimus G F180S is stuck on the bootloop mode. It gives an error
"Secure Booting Error! Cause: boot certification varify"
I cannot get it into download mode (my pressing both volume buttons and plugging in the USB). When I hold down the volume keys and then plug the USB, it just goes into the same screen staying there is a secure booting error.
I also tried doing a Hard Factory Reset (pressing volume down and power and plugging in USB), it prompted me to press the power button again if I wanted to factory reset, but once i pressed the power, it just gave the secure boot error again.
Could you please help me?
After I rooted the phone, I was trying to flash TWRP using Flasify App on google play when this happened.
I would really appreciate some help.
Its been stuck like this for days. Please help me
1) Familiar this message? Yes! can't hard reset or whatsoever
secure booting Error!
cause: boot certification verify
2) follow our dearest masters of XDA to boot into download mode
press down + up volumn button at same time
plug into computer
result: keep showing charging.... I wonder why my phone loves charging
3) Since I already tried 100 times pressing the button and won't work, is that any alternative way to flash my phone ?
download mode don't show
4) Somehow there is a price that pursuing free upgrade but end up messing our own phone....
need your help
Thanks for not giving up on me and I surely have been gone through lot of ways, but it just doesn't show the download mode and nothing I can do.:crying:

Yeah I have had that before. You need to change to a different rom. Seems to be a problem with something to do with different roms.
I unlocked bootloader and wanted to install Magisk with TWRP but it kept giving me Error 1 saying "boot image patched by unsupported programs, please restore stock boot image" so I searched for the boot.img, transfered to internal device of the phone and flash it but I didn't do wipe data and now my phone is stuck in "your device has been unlocked and can't be trusted" message. I tried powering off by pressing the power off button, it goes on black screen for a couple of seconds then gets back to the same message screen, same with trying to enter into recovery mode by pressing power and volumen down button, comes back and gets stuck in the same screen, I tried connecting to pc with usb but doesn't recognize it. I dont know what to do please help me
