Question

I team!

Before everything: congrats for all effort.  Easy Jtag Plus is a great tool.

Let's check the case: UFS change for Poco X3 Pro (Vayu)

•additional information:
CPU is not new
UFS is New (RPMB clean)

In my experience with change eMMC, RPMB clean after update FFU (great update, team), is just write eng firmware (Devcfg) device will start and will be possible to write RPMB in new Emmc: 
adb shell
qseecom_sample_client v smplap64 14 1

If just write a stock rom and don't use Devcfg file
 device will show:
Pres any Key to shut down
•no usb recognize
•no fast boot/recovery

So ... After change UFS for Poco X3 pro and write eng firmware by ISP connection (long time UFS  Samsung KLUEG8UHDC-B0E1) device show:

Press any key to shut down
•no usb recognize
•no fast boot/recovery

 

 
Have some opinion how to proceed?

I think  this process is possible because I saw a post in a relevant page:

Any Suggestion?

The Poco X3 Pro is such a solid device, and changing the UFS can really help improve performance and storage reliability if done carefully.

Thanks for the detailed explanation! I faced a similar issue after replacing the UFS on my Poco X3 Pro. Flashing the ENG firmware helped a bit, but the USB and recovery modes were still unresponsive. What finally worked was installing the stock MIUI with a pre-patched devcfg.img and fixing the RPMB using QPST.

Also, if you’re into firmware tweaks or testing game mods during your downtime, I’d suggest visiting https://freefireproxyserver.click/, it’s a great resource for modded APKs and handy tools.
