Nexus 5 stuck on Google Logo: failed to mount /cache (Invalid argument) - Nexus 5 Q&A, Help & Troubleshooting

Hello, I bought a Nexus 5 on ebay to because I wanted to put Ubuntu Touch on it, but it is stuck on the Google Loading Screen with the 4 dots.
I have tried going into to recovery mode, and wiped data/factory, as well as the cache partition, but in recovery mode, it says "failed to mount /cache (Invalid argument).
I have read that re-flashing the stock rom could fix it, but the bootloader is locked, so I cannot flash the stock rom. Can someone give me some pointers on what to try next.

Disable Android Lollipop Encryption

Hello everybody,
I managed to port a rom on my bluboo Xtouch (Mtk6753 android lollipop 5.1) and I modified the boot.img and google enabled Security encryption.
So now in security encryption is forced

And I can't change it. So I tried to reinstall the stock original ROM and also format whole flash with SP flash tool.
But nothing changes the data are still encrypted and I can't continue to develop my rom and install it with TWRP. I have always this error in recovery "E: Unable to mount '/data' "
I also tried to unlock the bootloader and did many factory reset...
If anyone has an idea ?
thanks in advance

[Q] OnePlus5 Encryption Unsuccessful Problem

I have unlocked my bootloader and installed TWRP. After doing so I tried to install Oxygen OS. The installation got corrupted when rebooting the phone and it popped up an error saying " Encryption Unsuccessful ". I have no idea how to resolve the problem?
1. It doesn't show any reset button.
2. If I try to factory reset install from internal storage not working.
3. If i try to use install from adb devices the the storage device is undetected by system.
I am completely broken is there any way to solve this issue. I have tried most of the solutions in internet nothing works? Please help me.

Cant install GApps on Lineage

Hi All
OK, this is a spin off from my "Help I bricked my S7" post - but is different, so I thought I should start a new post.
I have installed TWRP on my S7 (SM-G930F), but have been unable to install GAPPs... it seems that within TWRP the only partition it can see is the MicroSD card and I cant mount they stystem or data partitions!
I am using Lineage 19.1 (lineage-19.1-20220907-UNOFFICIAL-ks01ltexx) and trying to install MindTheGapps 12.1. I had this problem yesterday and bricked my phone, so thought that now I have it working again I would stop and see if anyone here can help?
This is a screenshot of the error/s when it tries to install from the microSD card in TWRP...

"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Can anyone give me some pointers before I brick it again
Thanks in advance
