M4300 Boot Freeze after FW upgrade
Hi I just went through the firmware upgrade on a M4300-28G switch from version 12.0.9.3 to 12.0.11.8. After the reboot the switch was not comming up again. Re-powering the switch and watching on ...
Hello
I'm happy to announce that support just shared a new firmware version (12.0.11.10) with me which, after installation, works.
Thank you NETGEAR!

Hi dialsc ,
Welcome to NETGEAR community! :smileyhappy:
I'm sorry about the Freeze on this M4300-28G.
Since this M4300 can not bootup normally now even powercycle.
Here is my suggestion to you for device recovery and troubleshooting(following screenshoot will help you on this)
1. Connect the Console port to M4300 and keep press "ESC" button when you see the key word "Freeing init memory"
2. Select “Active the backup image“ for workaround and then M4300 should bootup with backup image normally.
3. If system bootup successfully, export configuration file to local backup.
a) And also please export techsupport file and share to us for debugging.
b) If possible, please also send the full console log when this issue happened and M4300 can not bootup.
After you success active backup image and system bootup.
1. Please do not upgrade this M4300 for now and try to share more information to us for debugging.
2. The techsupport file is useful for debugging and also topology of this M4300.
Our QA have also try to reproduce this probably issue but no lucky to see it.
Hi DanielZhang
Thank you very much for your detailed answer and your help. I already went through the "recovery" by activating the backup image which worked, the switch is up and running again with the older firmware.
As for the test with an "empty" config. I will try that later today.
Meanwhile if you'd like I can send over the running config to you. Maybe Netgear's QA is interessted in?
Best and thanks again

Hi dialsc ,
Good to heard your M4300 bootup with backup image.
Yes, NETGEAR QA team need the configuration file and also techsupport file for debugging.
If possible please send it to us for analysis.(following is guidance for techsupport sharing steps)
BTW, if the upgrade is not necessary, please do not try to upgrade on this M4300 for now since we are not sure about this issue will happen again or not.
Thanks for your patience and cooperation :smileyhappy:
Hi DanielZhang
I did what you asked me to do and send all the data/files collected to the support mail address.
I hope it helps and if you need anything else please just ask/call/what ever... ;)
Kind regards
