Rooted storage problem - Nexus 7 Q&A, Help & Troubleshooting

I've been just plain unlocked and rooted for the past couple days, and decided to put my first ROM on my N7 today. I downloaded Glazed Jellybean, and since I was coming from a stock rom, it said to do the wipe/factory reset, which I did. At this point, I had about 4 GB space used, 1.5 gb free. I flashed the rom and it installed, but when I went to check my storage, I still had that 4 GB used, yet of course all of the apps were gone from the ROM install. Does anyone know how to get that storage back? Thanks

[Q] nexus 4 16gb version... after soft brick 5gb ???

hey, i'll be brief...
today (maybe yesterday for you.. nevermind) i was rooting my nexus 4 after bootloader unlocking... during the procedure my computer has freezed, so i rebooted it and after few minutes i tried again and this time i have correctly rooted my phone... then i flashed a custom rom and finally few hours ago i went into fastboot mode, erased all the imgs (userdata, boot, system, etc... don't ask me why i've done that, i'm very stupid...) and flashed the 4.3 factory image on the google site... and just now i've realized that my internal storage has switched from 12,95 GB to 5,6 GB...... I purchased the 16 gb version, but now i litterally have a 8 gb one... so tell me, is it a software problem? is it easily solvable or I have to ship the phone in warranty? please, answer me asap, i'm hopeless at the moment!!!
p.s. 5,9 GB is the TOTAL ammount that the os takes over, not the available..
I've had the same experience once,
Go to official android page, download the JDQ39 version and reflash it. Then optional for the cwm installation and others.
I had it a couple of times, so chillax.
yeah, i was already trying it... my router is very low-power now, so it is taking a lot.. omg this reassure me! ahahahahhaa i was going out of mind, thanks bro!

[Q] Where did my files go?

Long story short, I cleared userdata and rebooted to a fresh install of android 4.3, and my own files aren't visible anymore. I know they are still there as internal storage reports much less space than 16GB (it reports 6GB to be exact).
Is there any way to recover those files?
Similar experience
Out of curiosity, what ROM were you coming from before attempting to go back to stock. I had the same experience when resetting from ParanoidAndroid. My fix is here: http://forum.xda-developers.com/showpost.php?p=47254050&postcount=2

[Q] Lost Gigs

I upgraded to Lollipop on my 32 gig Nexus 7 it shows that I have 4.6 gig free. What happened to all my gigs and how do I get them back?

Been seeing this posted a lot recently, seems the answer is to do a factory reset.
Yeah it seems everyone does factory reset to solve this, and that's fine if you don't care about keeping your data, but I'd first try just using fastboot to flash system.img from the stock lollipop 5.0 firmware. (I sideloaded the OTA and didn't have this issue.)
The issue is that user data is flashed instead of erased when you loaded the factory image. A factory reset reformats it and restores the correct partition size.

Nexus 7 Flash to stock issue

So, I flashed back to stock to take the OTA using NRT, the process went off without a hitch. I realized once I got most of my stuff setup that I only have 6gb instead of the 13 or so I had previously. to be clear, I have the 16 gb tablet but now its showing 6 gb total. I wanted to see if anyone knows how to resize or re partition my device. Or if there's a way to roll back, I went back to my old custom rom and it still doesn't show the full space.
This has happened to me several times while flashing factory images. The only fix I know of is to do a factory data reset.

10GB of space unusable and un-deletable after ROM install

I installed the Stock ROM v4 and immediately after the install i noticed around 10GB were being used for nothing, but it was unusable and un-deletable.
Any thoughts on how to get that space back or redo the install so that doesn't happen again?
