Now, another thing disturbs me: when I tried to update, it just showed me an icon with a broken down Droid and the text Error! beneath it. I'm not soft-bricked or anything, just that I couldn't update. Could it be because I flashed another kernel?
Any modifications you may have made to your Nexus 7 (other then rooting and a Custom Recovery installed)
will almost certainly cause an OTA to fail... as an OTA first runs a checksum verification test on all system files to ensure they are the original system files.
If they've been modified by the user, they cannot be 'patched'
, ie. updated... so the OTA aborts with no changes made.
Anyway... you really should be posting your question(s) here...
...as the Razor recovery you posted clearly identifies your device as a second generation Nexus 7(2013), and as @Pirateghost
points out, posting that recovery in this forum could potentially mess up other peoples devices, if they were to flash it.
