I have two RB450Gx4 which were on RouterOS 6.48.6. When attempting to update to RouterOS 7.8 via WinBox both devices began to repeatedly reboot.
Using NetInstall I installed routeros-7.8-arm.npk however both devices continued to reboot.
Then attempted to install routeros-6.49.7-arm.npk via NetInstall and device successfully boots and starts up. At this stage I also upgraded the routerboard.
Then attempted to install 7.8 again, and device went back to reboot loop. Installing 7.9 also resulted in the reboot loop.
Logging into RouterBOOT shows the following
Code: Select all
RouterBOOT booter 6.49.7

We have also recently configured 30+ of the RB450Gx4 onto RouterOS 7.8 with only these two devices having an issue.
Any advice on how I can proceed or could it be a NAND fault?
Thanks
