4.2 update issue

I used an ota file some one posted to update to 4.2 and ran into a problem. I have a 16gb model and now only have the 8gb storage available. It seems the ota posted was for a 8 GB nexus and it possibly repartitioned my nexus to match the 8 GB nexus. I tried to search for a solution and couldn't find anything. Anybody know how to fix this.

That have nothing to do with the OTA. Mine is a 32GB and used the OTA posted all fine. OTAs are universal (Nasaki) regardless of emmc capacity.

What they said.
First, a non-compatible OTA would not work since it would fail checksum validation. Second, the updates are universal for the model (ie: same for 8,16 or 32). Third, the only low level flashing this update does is on bootloader and boot. It simply patches the files in /system and leaves userdata alone. So it's highly unlikely what you're saying happened. Or if it did, it was most likely due to something else. If your system's filesystem is really that messed up, you might need to reflash it to stock to get fixed. But I would suggest triple checking to make sure you aren't wrong.

[SOLVED]4.3 messed up my internal storage

So after spending a whole afternoon flashing 4.3 onto the N7 via fastboot and finally getting root to work, I connect my N7 to the PC and get the shock of my life to see my internal storage has shrunk to 6GB...it currently says I only have 5GB free out of 6GB...is there any way to fix this ? My N7 is the 3G, 32GB model running 4.3 with stock kernel, twrp and rooted.

Just edit the steps to adapt to our Nexus 7 PM me if you need help with that

Anyone ?

We've had that with the first custom roms. The only way to fix that, that I know know of, is to flash back to older stock rom, verify the storage is right, and try again.
I would download the 4.3 rom from another source and/or verify the MD5 package.
Just for laughs, perhaps you could try to reflash the kernel (which is what I think gives the reading).
That or you are the only person with a 6gb N7.

Well, I talked to two other people and they said this is bound to happen with flash happy morons like me who go straight for the IMGs...will try re-doing from step 1, or else I'll go back to 4.2.2...oh and 1 more piece of info...as I was done with flashing 4.3, my sd was formatted as well...

This has also happened to me on more then one occasion when flashing back to stock would show only 6/27.5GB available. Rebooting into recovery and reformatting fixes it.

i got that once...formatted all in Philz recovery...DONE..no problem..

[Q] My nexus 7 went down from 16gb to 8gb

Hello to all,
I have a big problem. I own Nexus 7 (2012) version with 16gb, but when I flashed KitKat 4.4.2 (KOT49H) via Wug's Nexus Root Toolkit v1.7.9, my Nexus went down to 8gb version (actually, I got only 5.9gb free space).
How is this posible? To went from 16gb model to 8gb model and most important, how do I get back to original 16gb of storage?
edit:haha, I don't know how but solution was this: I did full wipe and format data via cwm. Then it said that I dont have OS installed. So, again I used Wug's Nexus Root Toolkit v1.7.9, only now I flashed 4.4 KRT16S. And on my biggest surprise, now I got 27gb free space. I loaded it with movies and it's real space.
I thought that I know something about android, but now I'm confused very much. Merry Christmas to me with this extra gift
P.S. And to all of you ofcourse.
P.P.S. Would somebody like to try this also? Maybe you get extra 16gb, too!

Do a search. This isn't a new phenomenon; it only happens to rooters. Somehow, an undersized ext4 filesystem gets created in the userdata partition (which is substantially larger).
The exact origin of the problem is not clear, but is probably a bug in the bootloader.
The solution is always the same - to backup the entire tablet and recreate the /data filesystem (either by having the bootloader do it via a fastboot command or using "mke2fs" with a custom recovery).
While it is technically possible for a device to come from the factory this way, I highly doubt that is what occurred. And no, this isn't some kind of voodoo magic - if you can build a 29 GB filesystem on your device, that's only because there is a 32 GB flash chip in there.
In any event, if you look in the kernel log (search for messages with "mmc" in them) shortly after the tablet has booted, youll see the kernel identify the chip and it's capacity. That's a whole lot easier than speculatively unloading and reloading many GB of files.

I'll hope that I will get screenshots available during this evening, because tablet is not with me for the moment.

I'll try this voodoo method with friend's nexus 7 which is 8gb version and post results. It is really very strange that I manage to do this. I know that somebody much smarter then me will already came up with this findings, but I live in a hope :laugh: I hope that I accidentally somehow unlocked disc space. I already got theory that all nexus 7 (wifi) devices are the same in hardware and that they are only with software locked to 8, 16 or 32gb :laugh:

Reclaiming Storage

I have the AT&T version running OptimusG3 v1.4.1 with Dorimanx.
This is the best setup I've ever had on a phone. I want to keep Optimus and Dorimanx (I also use Philz Touch recovery).
Having said that, somehow along the way of flashing roms, I somehow messed up the partition so that my phone thinks it is a 24 gb version instead of 32.
Now if this were my old Sammy Note 2, I could flash it till I got it right with little worries. But I've bricked the G2 so many times that I would rather not do the trial and error dance at this time.
What would be my best option for reclaiming that extra storage?

There's no 24gb version of the phone. If you have something like 24.80GB of space available
thate because you have the 32gb model. The rest is reserved as a system partition and some other stuff. No you can't change it, especially with a locked bootloader.
Now if you have about 10GB of space available just search for the fix, in this forum it'd very easy to find.

reflashed to stock, sd size changed and no access to /data

hey guys
Been messing around with tablet to find best setup then to find netflix wont work. I have reflashed back to stock rom from lineage os. but now my sd card size is showing 16gb under storage space but if I look at it elsewhere its like 6gb, when it should be 64gb, I read this is to do with userdata but I cant find any userdata files to flash.
other issue is attempting to factory reset using twrp getting alot of /data/.... (permission Denied)
how can I solve these issues? and the streaming apps (netflix and disneyplus)
thanks guys

Your data partition is encrypted. I had the same issue and found this thread:

Seems to have worked, TWRP sees the full storage amount, but still trying to get Lineage loaded...

Having had this same issue recently TWRP will be your saving grace but before you go through the process in the link you should at least look at (while in TWRP) the WIPE section. Go through each of the listed options individually and hit the "repair or change File system option." What happened with mine is that the act of flashing stock changed The /DATA partition from EXT4 to NTFS and I Needed to change it back.
Regarding the Stock image you flashed double check to make sure its the one intended for your particular device storage size. Apparently there are different variants of the same stock ROM but with different PIT files (the file that sets your device partition.
One last piece of advise that may seem like a captain obvious is thing but I admittedly overlooked is when you flash your stock ROM, make sure to include not just the AP file, but also BL and CSC as well whwhenever you flash

I tried flashing Lineage and Havoc and was never able to get either working for this device which I'm sure is likely user error but I gave up either way lol

I actually got Lineage working fine on it. Once I got the data partition figured out I believe it was smooth sailing, though it was a while ago now.

Hey so I was able to get it up and running eventually as well but in the end wound up just running stock rom on this device as I was getting these weird "screen shatter" type glitches on bootup and so it wasnt really worth the hassle lol. Does rooting really even provide that much of a benefit for this device?

Why in the world would you go back to stock just because of these "screen glitches" when booting up? They are gone after Boot and don't cause any issues .... Also this might be caused by you being on an old (or newer but it's rather unlikely as I fixed this "issue" for newer ones) firmware (bootloader matters)
Stock is laggy and bloated while lineage is not.
Edit: Btw, which model and firmware are you on?
If it's P615 with BTK2 firmware I might need to update dtbo sources again and this "issue" will be gone
