Can't use L5 after update!

Hi,
Excuse me about my English, it’s not my best skill.

After an update few weeks ago, my L5 doesn’t detect the Hardware-Kill-Switches when I turn them on. I suppose the solution describe here could help me, so I try to access to my L5 through jumpdrive but I’m stuck.

I am on Kubuntu 20.04, I try the process on an Archlinux and a Kubuntu 21.10, every time I reach this state :

ailonn@ailonn-Oryx-Pro:~/librem5/jumpdrive » sudo ./boot-purism-librem5.sh
[sudo] Mot de passe de ailonn :
uuu (Universal Update Utility) for nxp imx chips – libpureos/1.2.91+0git6b465-0pureos+librem5.2-1-g5e5fee8

Success 0 Failure 0
3:1 3/ 3 [=================100%=================] SDPV: jump

The script never stop, the screen is black and the litght is kind of yellow. In this screenshot I build uuu with the instructions from the wiki.

Thanks you to have take the time to read this.

Someone has some tips to help me please ?
I’m available to any comments.
