Undo Format Data?

I am a relatively new android user but do enjoy flashing roms, kernels etc
My problems began when i was trying to flash a new rom on my Nexus 5
I was trying to flash this rom http://forum.xda-developers.com/showthread.php?t=2655722 but despite doing a factory reset and wiping the dalvik cache and cache it refused to boot in to the new rom
I tried to flash the rom multiple times but without success, eventually when trying to boot into recovery to try again i was greeted with an unthemed TWRP recovery asking for a password despite the fact that i had a custom theme and multirom installed I tried to proceed anyways but was greeted with E: unable to mount storage
In desperation i tried to solve this problem and found this

TWRP asking for password
After unboxing my Nexus 5, here's what I did:
1. Booted into bootloader
2. fastboot oem unlock
3. Flashed TWRP v2.6.3.0
4. Booted to recovery
The screen that greeted me says "Please Enter Your Password".
I can hit the cancel button below this which takes me to the normal TWRP screen. I then pushed SuperSU to /sdcard, but when I flash it it fails because it's unable to mount /cache or storage.
When I reboot to the system, it takes an awfully long time (approximately 30s) to progress past the "Google" screen, and then it just seems to sit on the booting animation forever.
Any help?
EDIT: Solved my own problem.
Hit cancel at the password screen, then go into Wipe and then do a factory reset by swiping. Then go back into Wipe and press the 'Format data' button. You have to type 'Yes', and it will take a few seconds. After that everything should work normally.

I now fear that i maybe without both a rom and all my files such as my music that was stored on my phone.
Is there any way for me to undo the damage i may have done to to my phone?

You can't recover the data. But you can push files over with ADB.

Hey Guys,
I am stuck at clockworkmod recovery menu... I am done wipe data/factory reset option, but after this when I have selected reboot system now option, device gets restarted and stucks at nexus logo menu.. I have waited for around an hour but there is no progress after this. Please help me, I have no idea how to go ahead with this.

Just download a ROM for your phone. Adb push it to your device. Wipe data and flash the ROM?

Cache Partition woes

I've had many problems with my cache partition. I was going to try and install a new ROM since my phone was working fine for a while. So I installed TWRP and rooted it. I noticed inside TWRP it said
E:\ Unable to mount cache".
I tried to mount it in TWRP and it wouldn't let me select it. I tried formatting/wiping the cache and it seemed to complete but then it displayed the same error message. After I tried to wipe the cache partition my phone was unable to boot. It was stuck on the swirling balloons before the android logo displays. So I downloaded the cache.img for 5.1 and flashed it. When I gave the command fastboot flash cache.img it starts erasing the cache and gets stuck there. The phone freezes and doesn't do anything until I power it off. So I am unable to flash the cache.img. My phone was stuck in a boot loop and doesn't get fixed into I going into TWRP and input this command from shell:
mkfs.ext2 /dev/block/mmcblk0p27
After I use that command the phone boots fine and everything seems okay. So now my question(s) is, does anyone know what is up with my cache partition? Why doesn't TWRP mount it? And when I do anything with the cache partition my phone stops working.....
I am on stock 5.1 with no custom kernels.

Exactly the same problem , the phone works, but does not wipe the cache , please help:crying:

Anyone have any ideas what is up with my cache partition?

Same here, phone working with no prob, but can't flash anything on twrp: fail with message Unable to mount /cache
Already tried:
-flash cache.img
-fastboot erase/format cache
Curiously, twrp can wipe the cache.

Go into Recovery and do a wipe cache again and wait for it to finish, it could last like 5~30mins so i recommend connecting the charger just in case then you'll be fine. If it doesn't work try with another custom recovery or go back to stock recovery.
This happened to me a while back and to a friend of mine a few weeks back thank god he called me since we both got a N5. :good::highfive:

It's a bug in the latest TWRP... Go back to 2.8.5.3 for the while. 

I solved this problem in such a way:
write to the console on the PC or TWRP
PHP:
adb shell
make_ext4fs /dev/block/mmcblk0p27
exit
Now , the cache is working , you can put whatever you want, but do not wipe cache dies again , this command is essentially wipe . Good luck

OnePlus 8T stuck on boot

Hello, I was using my phone normally and then I decided to turn it off because I was having a bug with an application, then I turned it on but in that process I accidentaly push one of the volume bottons and end up on what it seems a boot menu, I went for the english option and then to "exit" and "power off" so I can exit this boot menu, but it comes back again to this menu over and over I don't know why,.
I go to boot reason and appears this: fs_mgr_mount_all
Unable to parse kernel log.
I need help, don't know why I can't exit this menu because I entered by mistake and did nothing else than trying to exit. I have never root my phone or anything related to that, please help me to not lose my data!

Try booting in Recovery and clear Cache (only wipe Cache not Wipe all) and then reboot
Maybe this help you

Ok just done that but it is still stuck on boot, maybe there is another solution to this problem?

Hmm looks like your 8T is caught in bootloop. As far as i know there is only to try in Recovery the Wipe All step which deleted all on your Phone. If that also not works then MSN Tool which has the same result as the Wipe All, the only differnce is that MSN Tool sets up your Partitions fresh and complete clean.
But i can be wrong with that what i Knowing, maybe a more smarter guy can help you out with your problem.

If your phone bootloader not unlocked, the only way i know is fastboot flash .img file from official full update.zip
If that not work, wipe or MSM, but they all causing data loss.
