can`t Unlock the boatloader or enter the recovery (Stuck in 1+ LOGO) Plz Help

I Have a big issue and need your help

I was OOS3 and do all the correct steps to get modified TWRP to setup custom rom and succeeded on this they I decide to back agaon to OOS3 as it`s more sable

So I download OOS3 and flash it from my Modified Recovery and works fine

Than I decide to enter the recovery just to clear the cash for agood performance and here .. the issue started ...

when I click reboot to recovery , the mobile stopped @ 1+ LOGO So I remmember that this modified recovery is not working with oos3

so I get the steps for unloacking the boatloader again to flash the recovery compatible with OOS3

and HERE .. I see my device when I type
fastboot devices ,,,

but once I type "fastboot oem unlock" it`s show my ok and device rebooted in the same 1+ LOGO

SO I now Stuck in this logo

Cannot enter the recovery Or even the OOS3 just can enter the fastboat mode

Please I need your help how can I manage this
