Won't boot past boot screen

Hi everyone! I'm new here, please don't shout at me!
Basically, I've been rooting and installing recoveries images all night. But I've run into a problem. I was going to flash to the Super-Hybrid HD-Desire ROM by MicroMod777 (link to thread: http://forum.xda-developers.com/showthread.php?t=784260) but it won't install, and now won't boot past the Nexus colour logo with the unlock bootloader padlock symbol at the botom. Here is what I did to get to this stage:
Followed these guides: http://wiki.cyanogenmod.com/index.php?title=Nexus_One:_Full_Update_Guide
http://androidandme.com/2010/01/hacks/video-how-to-unlock-and-root-a-nexus-one/
I then downloaded said ROM and put it in my SD card like it said, and booted into ClockWork from ROM Manager. I tried to flash it, but it didn't work, coming up with this error:
E:Can't mount/dev/block/mmcblk0p2
(File exists)

E:Can't mount SDEXT:
E:Failure at line 24:
copy_dir PACKAGE:ext SDEXT:
Installation aborted.
I then did a factory wipe, and that didn't work, so I wiped the cache partitions. Nothing worked, always the same error. I also did a restore before I tried to flash for the first time, I've tried to restore that, but it doesn't work either; it also says that it can't mount SD-EXT, but I don't know if this is the error.
I can still get into the bootloader (trackball + power buton) and get to recovery through there, and I saw someone say in a thread here that if you can get into the bootloader it is basically impossible to be bricked. The phone will also not mount when I connect it to the PC, however the PC knows it's there, as I can see the phone, and on fastboot's menu it says 'fastboot usb'.
I hope some of you guys can help me! I really do love my phone, I need it ASAP! Ideally, I'd get onto the ROM I mentioned above, but restoring it to factory settings would also be perfect. Whatever is easier!
Thanks

[Q] Possibly Bricked A500

Hello,
I tried to move from one rom to another, but it seemed that the device got bricked.
Currently, it has Skrilax_CZ's bootloader v8 and TWRP recovery 2.6.3, which is working.
The problem is, that the file system got messed up, i think. When i start the recovery i see the following in the console:
Code:
Unable to mount '/data'
Unable to recreate /data/media folder.
Unable to find partition size for '/misc'
Unable to find partition size for '/boot'
Unable to find partition size for '/recovery'
Unable to find partition size for '/system'
Unable to find partition size for '/data'
Unable to find partition size for '/cache'
Unable to find partition size for '/flexrom'
Unable to find partition size for internal storage
Unable to set emmc bootloader message.
I see most of the folders in the file explorer in the recovery but they are all empty.
I tried wiping everything but still got errors. When i try to install any ROM, i get the same errors.
EDIT:
I installed older version of TWRP - v.2.4.4. There seems to be less errors with it. When i try to restore from a backup now i get: "Restoring data..." and the message ERROR after that. Interestingly, the CPUID now is all zeroes (000....) instead of the original one, which i have written down.
I think that some system directories are missing, but i may well be mistaken. Is there a way to recreate them?
Any suggestions?
EDIT #2:
I solved it! After a lot wondering i came upon this thread: http://forum.xda-developers.com/showthread.php?t=1516012
It helped me to get the tablet working with the stock rom, in case anybody else gets stuck like me. That is why it is very important to write down the CPUID!

Well thats a new one...I'd say yr memory chip is hosed. To have yr cpuid reported like that doesn't sound good. Try runnng babsector.rar to reset partitions...see post 2 in my root guide in my sig

Wow awesome, yep that euu can also reset partitions. As u say, keeping yr cpuid safe is THE most important things you can do...well done!

Can't flash rom

Hi,
i'm pretty new to this and i have kinda big problem. I had MIUI 7 rom installed on my S4 I9505, but yesterday after the update phone wont boot. I downloaded new .zip file, put it on SD card, boot into recovery, wipe everything and tried to install new rom. With no succes. I tried 3 differrent roms, i even tried with diffirent recovery, still nothing.
This is what it says:
Installing: /storage/sdcar1/cm-12.1-20151106-NIGHTLY-jfltexx.zip
Finding update package
Opening update package
Installing update
detected filesystem ext4 for /dev/block/platform/msm_sdcc.1/by-name/system
mount: failed to mount /dev/block/platform/msm_sdcc.1/by-name/system at /system: Invalid argument
unmount of /system failed: no such volume
detected filesystem ext4 for /dev/block/platform/msm_sdcc.1/by_name/userdata
Patching system image unconditionally...
And that's it. Previosly i was getting errors, status 0 and status 7 if i remmember correctly, but now not even that
Now what to do? Please be noob friendly At this point i don't even care any more what rom to install, stock or custom, but i think i would prefer stock.
Thanks for your help!
Edit: I found this guide, will it do it? forums.androidcentral.com/ambassador-guides-tips-how-s/499009-guide-samsung-how-flash-stock-rom-via-odin-new-interface.html
It worked. Admin, you can close/delete this thread.

"Failed to mount '/system' (invalid argument)", Help translating tech talk

To be quick, I have a very specific error in all TWRP versions on LS997 that won't let the system stay mounted while flashing roms, "Failed to mount '/system' (invalid argument)".
I believe I found a fix for it in a dead reddit thread, but I can't understand how to do it on an LG v20.
Help is much appreciated.
It reads
"for anybody that stumbles upon this thread: I got it working by using a parted binary and mkfs.ext4 binary.
I removed the partition and added it again with parted, don't forget to name it correctly. And then I reformatted with mkfs.ext4. Those three links might help:

I’m also looking at the thread, and the miui link is stale because miui cleaned their forum.
I tried erase data (entire partition). I tried wiping system data cache, no matter what I did it was error 7 or unable to mount system.
I’m suspecting it might be which kdz I used for the downgrade but honestly it can’t be the case because I did this before 2 months ago and it was ok, now I can’t do anything.
