Probably missing QCN data.

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 realize this topic was last active a while ago but I made the same mistake with my RM520N-GL. Can I have the file and recovery instructions too? Thanks in advance.
