All operation for clear pass work with userdata or another (not system) partition
If you device not boot after you action, it's may be:
1) you may be damage PCB (device board)
2) you may be damage boot or system partition (you action is not be only press "Remove pass" button)

if you demage PCB - you need use microscope and restore it
if you damage boot or system partition of eMMC/UFS - you need restore it via original firmware or dump file (with dump file you need backup secure partition before)

thanks right now the phone is detected as qualcom in the Port...

I wonder if there's a full dump firmware of this y91 vivo 1817 that i can download. I would appreciate if you could share that file. I'm using the old hardware easy jtag not the plus version.

Is it possible to flash and revive this using my old hardware and easy jtag plus software?

i have already firmware Vivo_Y91_PD1818F_EX_A_1.8.25_LA.UM.6.6.2.R1-04200-89XX.0_QFIL

is this setup ok?

I can flash y91 using my old hardware and easy jtag plus software?



should i proceed to write now?

Do i need boot config file? or proceed to write?

you can write boot config by Preset or from ExtCSD file from this device
it's needed when you replace eMMC

you need to do what you understand.

if the program does not require you to have a file there, then you can do it without it
