QUERY : Should I be concerned regarding

i. (bootloader) platform: HBOOT-8064

ii. (bootloader) hbootpreupdate: 11, because in Kairi's firmware zip the android-info reads

1) CID H_061 (I changed it to 11111111)

2) hbootpreupdate:3 (This I did not change)

2. Relocked the boot loader (after checking if I could unlock it again through the previous code.bin. I did this successfully but without Selecting 'Yes' option at the end of the process on my device)

C:\Fastboot>fastboot oem lock
