I did not find similar threads on this so im going to say it for the final time....
Wiping by factory reset, wipe cache,dalvik cache and wiping battery stats is not wiping properly!!!
To install a rom freshly you wipe with the following correct procedures:
1.format system
2.format data
3.format cache
no need to wipe anything else. This is how u wipe properly before installling a rom. not by factory resetting by THIS.
Hope i helped many

wipe data/factory reset
wipe cache
wipe dalvik cache
I do all of it. Wipe data/cache/dalvik/battery then i format system/data/cache/boot

It would be good to note that the factory reset option in CWM does this. The one in the actual ROM I'm not sure of, but it probably doesn't.

Select “wipe data/factory reset
Select “yes”
This guide is not proper
Sent from my Nexus S using xda app-developers app
full wipe / changing roms:
1. wipe data/factory reset (this formats /data, /cache and .android_secure on sd)
2. format /system, /boot
this leaves you with a "virgin" phone, only bootloader, recovery and radio are left. dalvik-cache resides on /data, so it's gone already.
3. flash rom
4. optional: gapps & custom-kernel. no need to let the phone boot & settle before flashing them.
5. reboot
just updating rom:
1. flash rom-zip
2. wipe /cache and dalvik-cache
3. reboot
optional: if using a custom-kernel, flash it again after rom-zip. most custom-kernels have a script that automatically wipes /cache & dalvik during kernel-install.

I have always done what jayjay is stating...
And also front to back for me...
I restart my phone because it did a lot of time to reset cache. I regered the time I did it but was late.
Now my phone opens but does not have mobile network and cannot access my /sdcard/
From recovery I can see my sdcard. What can I Do?
Are you fully stock? If so, then format /cache partition and then perform a factory reset via stock recovery.
If you aren't fully stock, and use a custom recovery then I would suggest you to perform a factory reset from the custom recovery (it won't wipe internal sd)..
If it still doesn't work then you need to go back to fully stock by flashing the factory images from Google.

Yep, just keep wiping / formatting cache until it fixes or fastboot flash the stock cache.img

I am not stock at all. I thought if I could copy sdcard to otg before all these.

Just flash the stock recovery via fastboot and then format cache multiple times until it successfully formats! Your data won't be lost.
Since you rebooted before the cache was formatted, it has ended in a messed up /cache partition.
If you want to backup data, you can use adb pull from recovery...
See above
Edit.. By that I meant my previous post

Now. I am pulling my data and then I'll flash stock.
I have a backup before the mistake. If I restore it?

You can try to restore the backup but I doubt if it will solve the issue. However, there's no harm in trying..
The cache partition is messed up.. It needs to be formatted first. That's why I suggested you to go back to stock recovery and format cache...
I have tried wiping cache on Philz Touch and twrp and it didn't solve my problem. I had to format the cache partition using the stock recovery and voila! Everything was fixed.

Yes but if you're flashing stock recovery fastboot you may aswell flash cache.img instead which is a well documented fix in this forum

My bad. I understand to have done this from TWRP. I haven't tried yet to do something from fastboot due to the backup.

Flashing the stock cache.img won't wipe your saved data or backups.. There's no harm in trying.. However, if you're skeptical, adb pull all your important stuff and then do the flashes!
Finally I flashed cache.img and seems that everything is good again. Thank you for your help.
For some reason, I have to factory reset my phone
http://forum.xda-developers.com/google-nexus-5/help/disappear-hard-disk-t3222734#post63254887
Just wanna know, since I have titanium backup on my nexus 5 devices. Does a factory reset (or any kind of wipes) wipe the internal storage of my phone (including the backup).
If so, how should i proceed with my backup if i wanna factory reset the phone
Thanks.

Wait what, why do u need to do a factory reset, and yes, as the name suggests, it leaves the device in the same state that u received it in, blank, but why would u need to wipe the device, I'm going to check out the link, bcuz now I'm interested
I have never seen this happen before and I've owned nothing but Nexus devices, well, to answer your question I have to ask a few, are u rooted, do u have a recovery installed? If the answer to those two questions is no, then connect to a computer, copy the files in your internal storage and place them in a safe folder on your computer, proceed to wipe the device as stated, then copy the files back onto the device, should take care of your internal storage.

That might work, in theory it should, as long as u go back to 5.1.1, or u could just make a data only backup in twrp, download the factory image, whether it be 6.0 or 5.1.1, use the pc and adb to manually flash the images, do this
1) make data only backup, move that backup to pc
2) extract the images, both the tgz file and the zip file inside to a safe location, u only need the radio, boot, system, and userdata images if 6.0, just system and userdata if 5.1.1
3) use adb to flash these images like this:
fastboot flash radio "radio.img"
fastboot reboot bootloader
fastboot flash boot "boot.img"
fastboot reboot bootloader
fastboot flash system "system.img"
fastboot reboot bootloader
fastboot format userdata
fastboot reboot bootloader
Then boot to recovery, flash your backup and that's should be it

Few questions
Do I have to reset using stock recovery? Or twrp reset will do?
Can I just reset under setting?

No u can't use the factory reset button in settings as the stock room won't recognize twrp, u can however use twer and wipe cache, data, and dalvik cache, or just do the reg factory reset wipe under wipe which should work as well as a factory reset, why are u trying to factory reset tho, if I might ask

because my nexus 5 showing 14gb instead of 32gb. I heard a factory reset will help the problem. I just dont know which factory reset (recovery or in setting) to do.
but if i use twrp wiping cache, data and dalvik (leaving system and internal storage alone).... will it wipe my lollipop os too? will it wipe my storage too?
what is the different between the factory reset under setting and the factory reset under twrp?
sorry for so many questions....

Ok so to answer your question, u can wipe anything EXCEPT Internal Storage, system, and boot and you won't lose anything, personally I would do this, boy twrp and use the regular factory reset, this will error everything except got the OS and internal storage, if that didn't work then I would manually format the partitions
