Hello kappa11,

 
For guide on how to perform USB boot recovery please go here. Do you have backup of the data save on the NAS?

Hello, I have already read this part and it is after that that I try to install the 
firmware 6.7.4, no I did not make backup since the bays 3 and 4 of my nas are in raid 0
Thanks for your reply

RAID 0 has no redundancy, so backups are more even more important if you use it.

In general, RAID is not enough to keep your data safe.  Backups (on other devices) are needed to do that.

excuse me i meant raid 1, what do you propose as a  solution ?

If this has been going on for some months, you should probably engage paid support.

Does the system boot up in tech support mode?

[kappa11]

yes i think , is that all usb keys are compatible to start on ?

before seeing a paid supporti would already try to do a factory reset, and then pay the support because of an update 6.7.3 that did not work that would really bother me.

before doing a factory reset i would have liked to try to boot on a usb key or other.

sorry for my poor english

thanks for your reply

Not all USB keys are compatible.  Based on posts here, older keys are more likely to work.

I understand that paying for support would bother you.  But wouldn't losing your data bother you more?  Note a factory reset will destroy your data.

[kappa11]

pay the support because of an update bug ??!! the nas work very well before the update 6.7.3, it would be a mistake on my part i would understand, especially that the bug has happened to several people , i will try to find older usb keys and try this before a factory reset

[StephenB]

It's your choice of course, and FWIW I don't work for Netgear.

Does https://nas-ip-address/fwbroker respond? (use the real ip address of the NAS of course).

[kappa11]

no the nas not respond, it displays on the lcd screen :

lcd-panic _handle _rt7d

You could possibly try booting off USB into a tech support mode like state.

[kappa11]

ok my nas is boot on tech support mode

[kappa11]

is that the OS reinstall of the boot menu causes the data to be lost on the disks 2,3 and 4 ?

thanks for your reply

A factory reset will destroy data.  

An OS reinstall generally won't.  It will reset the admin password, reset the network configuration to DHCP, and turn off volume quotas.

ok thanks for your reply, my problem was resolved using usbrecovery.v2.0.R15-T3

[mdgm-ntgr]

Glad that resolved it. I thought it might help. It's got some changes that mean USB Boot Recovery will work more often than before.

[kappa11]

yes i took the same usb key already tried with usbrecovery V2 t14 but the boot does not launch ( for me an unrecognized usb key problem), with the version usbrecovery.v2.0.R15-T3 you gave me the boot started in 5 seconds

thank you again for your help
