Error when installing update via ADB and OTA on Nexus 5

Hey guys!
Firstly, I've tried installing the 5.0 update on my nexus 5. I tried via ADB so downloading it and then putting it onto my phone by putting my phone into recovery mode, and then applying update from ADB, however on the phone it came up with an error which was:
"/System/fonts/ROboto-BoldItallic.ttf" has unexpected contents.
E: Error in /tmp/update.zip (Status 7)
Installation aborted. " - I have tried deleting this file but just can't seem to be able to due to it being a read only??
I then waited until the official update was pushed to my phone, which was about 30 minutes ago, however that then gave me just an "error" after downloading, then restarting and trying to install.
I'm on stock firmware but I am rooted -Any help or advice in the right direction will really be helpful, and greatly appreciated!
Thanks
Need to be fully stock or you'll fail. Should be a link in my signature about update options...or at least how to get lollipop and root.

[Problem] Samsung Galaxy Note N8000 bricked

Hi, I've got a little problem, yesterday I tried to flash Omni ROM and I somehow managed to brick my device. Before I was running on android 4.1.2 with root, downgraded from 4.4.2.. Once I downgraded the android, the device couldn't be recognized by PC, so anytime I try to connect my tablet to PC it just gives me "USB not recognized" message. So, flashing ROMs via ODIN is impossible. (Tried to install/uninstall Kies & drivers many times, aswell as changing ports)
Also, because I'm a genius I have stock recovery on my tablet (Android system recovery <3e>). Which is another problem because whenever I try to flash any .zip file from external SD it gives me following message: "E:failed to verify whole-file signature" (2×) and "E: signature verification failed". I tried to flash stock ROM, which didn't worked, and a few custom ROMs such as Cyanogen mod. None of these worked and I ended up with the same error message.
On top of that, it seems that previous ROM is gone, because Recovery mode won't load /system & /data folders. Is there even a way how to save my Note? If there is, I'll be more than happy, and very thankful if somebody helps me.
#Edit 1
I can still transfer files from PC to SD card that's in the device. However, this doesn't seem to be very helpful since I can't disable that file verification.

Partition Error after Failed Flashing Stock ROM

hi all,
i have a problem with my xperia l. here's the story :
originally, i have xl with cm12 installed + re-partitioned internal (i'm using this guide), but i have stability issue after some time. then i tried resurrect remix rom, but i still have my problem (even worsen). so i was thinking about checking with stock rom, and i tried to flash stock rom back. but there's a error when processing userdata.sin on first try. i thought my tft was corrupted, so i tried to re-download it and tried flashing again, but the error still there.
after third attempts, the error message started to differ (forgot to log it ). so i tried to get into recovery, but i found error about "failed to mount /cache", "failed to mount /system" and so on. i have tried to mount manually in recovery menu, but failed, and sdcard read 0mb.
i have tried to solve by myself and some solution from forums, and still got no luck with it. what i have tried :
- trying to re-flashing tft again and again. latest error when processing loader.sin :
ERROR - (X10flash.java:520) - Error in processHeader : 22 : The device does not recognize the command.
- trying some recovery like cwm, thunderzap, twrp (i tried after read this post), but no luck and can't find restore filesystem menu).
- trying accessing adb, can't get in
- finally able to get into terminal from twrp, but only found parent folder without anything inside.
so, i think the partitions are damaged or something happened to them and i can't access them.
please help.... :crying:
NB. currently boot into fastboot, flashmode, recovery, charging, led, flashing boot.img, and external sdcard still working, so i hope my xl still can be saved :angel:. and i'm sorry for any typo
UPDATE :
finally hardbricked my phone. i'm getting impatient waiting some reply and no luck searching forum. so i messing around by myself, and found problem on superblock. i've fixed superblock once on linux, but in adb some commands are unavailable, and i can't search for backup superblock, so i tried to reformatted it (followed guide from some nexus forum, well, thinking androids have same base), and then i accidentally disconnect the usb. next is, well, i screamed.
Did you find any solution of this problem????
