RM502Q-AE stuck in FTM mode after firmware upgrade

RM502Q-AE flashed with QFlash_V6.4, “RM502QAEAAR13A02M4G” image, now it’s stuck in Factory Test Mode.
CFUN returns 5

Probably missing QCN data.
Please help

Dear @victors
As you know, every module has different parameters, if you restore the QCN which from my module, I am not sure if your module has any unexpected problem. Because when every module will do calibration before shipping.
But if you don’t care this, I can share a QCN to you.

I flashed it with QFlash, but I think I used the wrong file, “partition_complete_p4K_b256K.mbn”
So now it’s stuck in FTM. Is there any other way to fix it?

Dear @victors
The other way is return back to your provider for restore, I am not sure whether your provider will accept.
if you ship it to me, the freight also is expensive.

OK, let me try the QCN file then. I do have QPST_2.7.496 program.

Dear @victors
I have sent QCN and user guide to you via Message, please check.
