Upgrade --> No boot anymore

[Diako]

I backuped the boot partition (the only i can see on my Mac) and i replaced the content of this partition by the content of a raspbian boot folder found here : https://www.dropbox.com/s/84r95jovi4rlv64/raspbian-boot-folder.zip

The RPi starts booting but something is wrong and the boot didn't end.

So i replaced the cmdline.txt from the raspbian boot folder on the sd card by the cmdline.default file (renamed of course) from my backup and i have the same problem (no boot and black screen).

Here is my cmdline.default file content :

Code:

telnet zswap.enabled=1 zswap.compressor=lz4 sdhci-bcm2708.sync_after_dma=0 dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootflags=subvol=root/@,thread_pool=2,autodefrag,compress=lzo,commit=120 rootfstype=btrfs rootwait smsc95xx.turbo_mode=N logo.nologo quiet noswap loglevel=0 mod_scsi.scan=sync partswap startevent=mountall splash nohdparm --startup-event mountall

Can someone show me the content of his functionnal cmdline.txt file content plz ?

This time i put back my boot folder backup on the sd card and i added two options in cmdline.txt file : debug rescue

I have finally something on the screen and i can see a error : Kernel panic - not syncing : no working init found.
I put a printscreen of the message in attachment of this message.

Do you no what is happening and how to fix this ?
