IdeaPad Gaming 3 15ARH7 (82SB) - Cannot boot ANY OS after NVMe replacement​

Problem:
After replacing the failed M.2 NVMe SSD with a new one,
the laptop cannot boot ANY operating system.
The original SSD was unrecoverable (cause unknown).
The replacement SSD works perfectly when tested
externally on another PC.
No physical damage was found on the motherboard.
No drops, liquid damage, or external impact occurred.
The only action performed was the NVMe SSD replacement.
Despite this, the laptop immediately lost the ability
to boot any OS after the replacement.
Tested and failed:
- Windows 11 (multiple methods)
- Windows 10
- Ubuntu 22.04 LTS
- Lenovo USB Recovery Media (official tool)
All failed with same symptom:
Logo appears → spinning circle → restart loop
BSOD codes observed:
- KERNEL_MODE_HEAP_CORRUPTION (0x13A)
- SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
Current theory based on research:
EC firmware (ITE IT8227) corruption causing
incorrect power sequencing during OS boot.
BIOS POST works fine but full OS boot fails.
Has anyone experienced this issue or found a solution?
Any help is greatly appreciated.

****---Thank you ThienBui!I already have these files downloaded.My question:Should I reflash EC chip (EC_HLG52204.bin) first?Or reflash main BIOS (32mb.bin) first?My tests show:- Lenovo Diagnostics PASSED (all hardware OK)- Safe graphics mode: kernel starts but hangs- Verbose boot might help identify exact faultIs there a known EC firmware bug on this board?Should I try EC reflash before main BIOS?

If the problem is not detecting nvme, you need to buy a $35 patch to fix it

ThienBui, thank you for reply.BUT: The problem is NOT detecting NVMe!Test results:✅ NVMe COMPLETELY REMOVED → same problem✅ Lenovo Diagnostics boot successfully✅ All hardware tests PASSED (CPU, RAM, PCIe, iGPU)✅ Safe graphics mode: kernel starts but hangsThe laptop cannot boot ANY OS even with NVMe removed!This is NOT an NVMe detection issue.This is kernel init failure during ACPI/PCIe enumeration.Suspected:- EC firmware (ITE IT8227) corruption- dGPU (RTX 3050) PCIe fault- VRM/Power delivery issueShould I try:1. EC chip reflash (W25Q16JW)?2. Multimeter test on PUZ15 VRM rails?3. Component-level diagnosis?Please advise on correct approach.
