Good afternoon, such a question
There is ssd pm961 SAMSUNG MZVLW128HEGR-000L2, there was firmware 4L1QCXB7, Lenovo (probably), at first I did not find for Lenovo, but I found HP CXB73H1Q from HP, I ran it, it seems to work, but continuing the search, I found a fresh firmware 5L1QCXB7 from Lenovo . but no matter how I tried, I couldn’t get it anymore, authentication from HP interferes
Is it possible to flash it on lenovo? or from HP is a sentence? this link download firmware https://dropmefiles.com/3i2to
