I have an RB750Gr3 which boot-loop, i try netinstall,

netinstall procedure run normally and upload software OK but it continues rebooting

Somebody can share with me the repair guide document for this reference to check if there is a hardware failure?

Netinstall with 6.48.6, but after successfully netinstall,
shutdown the device,
power the device while pressing reset, but just when someting light, release instantly reset,
if boot, first thing you must do is update routerboot inside winbox.

Surprised??? :unamused:

What probably is happened: writing error on nand offset, replace some bits inside routerboot code.
That procedure boot the device with factory routerboot.
When booted, simply reflash current routerboot fix the error(s).
