My Zenfone 2 is showing usb icon before boot

[sujaygiritthara]

Hi.
I recently saw my Zenfone 2 was not booting and it was showing USB icon. I think upgrading to Android 6 caused this issue. I cannot boot into recovery mode. I upgraded to Zenfone 5z and I am planning to upgrade to the upcoming Zenfone 9.
Please help me fix the issue.
Thankfully I had an old google account and I was able to back up the files of my old Zenfone 2.

@sujaygiritthara
Could you please tell me which Zenfone 2 you are using?
If the USB port is unavailable, I would recommend you to use SD card for data backup.
Sorry for any inconvenience it may be caused.

@Falcon_ASUS It's the Zenfone 2 ZE551ML, The 2gb ram version.
I think I flashed the wrong update file for updating to Android 6 but it was still working for a few days even after flashing wrong update file 🧐
Sorry for late reply.

I backed up all my files earlier.
