[Q] Only 6gb of storage after 4.2 update? (16gb Nexus 7)

I just updated to 4.2 from 4.1.2 by booting into the boot loader and manually flashing each partition using fast boot. The only exceptions being the boot loader I itself and recovery which I flashed clockwork. After booting I into 4.2 I noticed only 6gb of storage was available for use (I have the 16gb version). I know 4.2 made storage changes due to multi-user, but something appears to have gone wrong.
My partition table is as follows. I see the 16gb partition, but can't find then in root explorer or any other app.

Anyone know what might be up or how to fix it?
Also noteworthy, since I used fast boot and never did anything that should have wiped my sdcard, everything is now missing on my sdcard anyway... And I can't find where it went for the life of me.

Reflash it
You may have to reflash back to stock and then get the ota update but let it install itself.
Then root it and install recovery.

It is for development purposes. It is basically the stock firmware minus the kernel and recovery.

If someone can assist with getting the kernel without root I would be forever grateful. If it is unpossible then please let me know as well as I cannot find a root method that works.

So, what you basicly need is someone with linux who can make a system.img from this, and add supersu and su binary?
And then someone who makes a factoryreset and flash it in odin I guess..
That person might then be able to extract recovery.img and boot.img. Am I right?

You don’t NEED linux, you can use Cygwin with windows, but yes someone can then make system.img or system.tar.md5 with supersu and su.
From there if a root shell is obtained recovery and boot partitions should be able to be extracted from the phone.
Then insecure kernel and custom recovery can be installed.
I’ve done something like this with the T989 but this phone is for someone at my work and so bricking is an issue unlike if it was a personal phone as well there is less motivation to do it if it isn’t mine.

Yes just like that minus the need to unpack it because it is just a tarball so 7zip or whatever should open it fine. I am at work but I believe my home computer has either a linux vm installed or Cygwin with dsixda’s kitchen.
I should be able to manually or through dsixda’s kitchen add supersu and su convert to a odin img and flash.
If it successfully roots so I can at least get a rooted shell so I can dd if=/dev/block/….. of=/sdcard/…img to get a recovery.img and boot.img then carefully cook up a TWRP or CWM recovery to flash then make a “custom” or modified stock rom to flash with insecured kernel.

Anything new on how this is going?

I added SuperSU.apk and su binary.
Scared to flash it without a known good working factory image. Need to read up on a couple things a little more like triple check I can flash just the system partition without boot, etc.

Excuse me if this may come across as stupid or ignorant, but to my understanding the SGH-T599 seems to be an alternative version of the S3 Mini , I think the main difference is the screen size? That being said, can you not use the current existing kernel, boot.img of the S3 mini? I'm basing this off the fact that I had soft-bricked my phone by attempting to flash CWM Recovery but it didn't work, and I couldn't get myself the stock recovery.img file so in an attempt to revive my phone, I substituted that with the S3 mini's and it worked. Although at first every time i turned on and off the phone it displayed noise (TV Static) but it no longer does so.
I would offer being a test monkey, but this is my only phone and I do not have any other phones that I could use in the scenario it does get bricked.

I think it will be fine to flash system.img only as long as you don't use any pit and repartition. Factory reset first to prevent bootloops.

Are you saying you used a boot.img from s3 mini?

What exactly did you use to get it up and running, just the recovery.img, system.img, or boot.img (kernel) you flashed or some combo?
Looks like processor, screen and possibly bluetooth are different
T-599 vs i8190

I just flashed the recovery.img, and (incorrectly) came to the assumption that the boot.img and system.img would work on the phone as well. In fact, I realize I can't access recovery. I was asking whether that the S3 mini's boot.img would work on the T599V as well.
Also, according to this link: http://www.sammobile.com/2012/11/24/review-samsung-galaxy-s-iii-mini-gt-i8190-2/
it says the S3 mini uses the U8420 chipset as well, which is why I thought the phones were similar.

The site you linked doesn't mention the SGH-T599 just the GT-8190 and the GT-i9300, did you send the right link?

According to http://www.gsmchoice.com/en/catalogue/samsung/galaxyexhibit/ it's built on same board. ST-Ericsson U8420.
It' same for i8190, some sites say U8500 others say U8420.

The Cydia Impactor root method works on the T599, I just did it to mine. Stays rooted on reboot.

Cool
So, first guy who "dd" will be hero of the day
If partition layout is the same as i8190 it should look like this.
Code:
GT-I8190 PARTITION LAYOUT
Official Name * Fs * Mount point * Known as * Contents
/efs * ext4 * /dev/block/mmcblk0p11 * Efs folder *Device IMEI,mac address etc
/modemfs * ext4 * /dev/block/mmcblk0p12 * Radio *
/SdCcard * vfat * /dev/block/mmcblk1 /dev/block/mmcblk1p1 * Internal sd * Your stuff
/boot * emmc * /dev/block/mmcblk0p20 * kernel/zimage * Drivers etc
/recovery * emmc * /dev/block/mmcblk0p21 * Recovery partion * ??????
/system * ext4 * /dev/block/mmcblk0p22 * System folder * The operation system
/cache * ext4 * /dev/block/mmcblk0p23 * Cache partition * Update.zips csc,samsung and carriers customizations

/.lfs * j4fs * /dev/block/mmcblk0p19 * param.lfs ## * splash screen,charging animation download mode pngs, etc
/data * ext4 * /dev/block/mmcblk0p25 length=-16384 * data folder * Your download apps, current device and use, settings

I guess boot, recovery, and param is most wanted

Looks like it matches pretty well

So, I used the Online Nandroid app, it detects the T599 as "codinatmo" and doesn't have a patch available.
Manually chose the "Samsung Galaxy S III mini GT-l8190" patch and installed.
Was able to back up boot.img and recovery.img, both 16MB.

Need a copy of mmcblk0

Hi guys,
I am in desperate need of a raw img of mmcblk0. All I need one of you to do is get an adb shell or in terminal emulator with root type:
dd if=/dev/block/mmcblk0 of=/sdcard/unbrick.img count=524288
This creates a raw image dump I can use to help unbrick my device. It does NOT contain any sensitive data like IMEI or ESN, etc... I need MJE on Verizon Note 3 specifically. Thank you very much in advanced!
EDIT: 2/14 11:15am CST I am still in need of MJE N900V image. Surely would appreciate anyone with the time.

Sorry I'm in a bit of a panic. Trying to remember how to piece together a debrick image. Appreciate your patience again.
EDIT: Here we go Link

Hi guys,
I am in desperate need of a raw img of mmcblk0. All I need one of you to do is get an adb shell or in terminal emulator with root type:
dd if=/dev/block/mmcblk0 of=/sdcard/unbrick.img
This creates a raw image dump I can use to help unbrick my device. It does NOT contain any sensitive data like IMEI or ESN, etc... I need MJE on Verizon Note 3 specifically. Thank you very much in advanced!

Actually it DOES contain sensitive data since it contains ALL 32GB of the internal flash
You need to be rooted and with a decent busybox and do more like:
dd if=/dev/block/mmcblk0 of=/sdcard/unbrick.img count=524288
(this will create a 256MB image).
IMHO you also need to create the debrick image on the same family product - it would be VERY interesting if that would work from a verizon developer edition model (and I would really want to see that tested) but I have some doubts. I would also be interested if any other debrick image would work - I assume you have N900V but IMHO it would be again VERY interesting to try with a N900W8 debrick image (but be very, very careful when you later write stuff with the modem-related stuff, which is very different in N900W8 and you really want to keep your N900V modem and stuff ).

I guess I need to go looking for the right threads, but is it correct to say that the SDcard unbrick method (Qualcomm phone versions) only provides a kind of volatile boot scaffolding so that the device owner can enter Odin/download mode... and that no flashing of the device occurs until the owner actually performs the subsequent flash operation using Odin? (That is, none of the content of the unbrick image is ever written to the device being rescued?)
A second question is whether version locking occurs - I thought I saw someone claiming that a prior release unbrick image, even if taken from the same device (e.g. MI9 or MJ7 prior to a MJE upgrade) will not launch into download mode - is that right?

That is somehow true, but IMHO if all relevant partitions are wiped on the internal flash (from SBL1 to ABOOT) then all those will be read from microSD and have the code and signatures from there, and the "Odin mode" itself will be the version from microSD.
And here we have a number of interesting paths:
- the signature/hash on SBL1 itself is similar among Note 3 versions - that would result on all steps up to and including ABOOT being valid, so the "special Odin mode" will be entered; if the signature/hash on SBL1 is NOT similar between Note 3 families (or even before and after a major bootloader version) not even the "special Odin mode" will be started;
- if "special Odin mode" is started we can see another fork - if the "downgrade limitations" are part of the microSD code itself then you will be able to write any single firmware you were able to write when the internal SBL1/ABOOT was at the same version as the microSD SBL1/ABOOT - in other words you will be able to downgrade as far back as the microSD SBL1/ABOOT will let you!
- however there are some reports that the "downgrade restrictions" are actually stored in the internal flash in the "invisible/protected" regions there - and can be reset with special JTAG-like hardware:
http://forum.gsmhosting.com/vbb/f672/regarding-knox-s4-1775213/
Even in that last case there would still be a small chance that the "downgrade restrictions" might be skipped when booting from microSD since the internal flash could be considered at that point "less reliable" (or hopefully somebody at Samsung forgot to read that extra info on this special path - we can all hope )
So yes, I have also seen some people claiming stuff but I would still like to see more detailed tests on it with detailed reports on what is failing at what point! And especially on the microSD with the N900W8 "happy bootloader" or even with some much earlier "early development bootloader" (I have seen something like that mentioned somewhere)!

My theory on this (for public, bftb0 already knows) is you can boot anything that isn't fused to a lower binary counter, and since these values are inconsistent with firmware updates, it gives you a little wiggle room. AKA if A flag in ODIN is A2, you can not use an A1 aboot (MI9), but I (think) could use MJ7 since it's counter value is 2, same as MJE. These values are stored in AP RAW ANTI ROLLBACK in QFPROM. It is my belief that these values are also accessed from the shadow register as opposed to being read every time, since I was able to downgrade and replicate. I'm almost positive it's pulling these flags from RPMB. I'm extremely curious what P is since I may have full control. P1 changed to P0 when I downgraded my SBL1, TZ, and RPM to the testbit bootloader leaked by designgears, which doesn't make much since I believe all three of those have their own counters.

well ryanbg can summarize when he gets some free time (and I think that there are further experiments in the queue) but an initial attempt at performing a rescue of his bricked retail SM-900V phone (which was on MJE prior to hard bricking by a TZ partition mod) using a 200 MiB dump of mmcblk0 from a MJ7 device resulted in .... nothing.
I haven't seen anything in any of the posts so far about folks talking extra precautions involving repair of the secondary GPT (after doing a raw dump of the unbrick.img to their SDcard media), so I suppose that means that the SDCard unbrick method is - when it works - supposed to be insensitive to the fact that the unbrick SD Card does not have a complete UEFI set of primary & secondary GPTs - and might even have garbage sitting at the secondary GPT offsets.
For the MJ7 trial, we used dd if=/dev/block/mmcblk0 bs=4096 count=50000 (200 MiB) which is sufficiently large to capture everything including some amount of slop at the beginning of /system (p23). I thought I saw a post where someone was using 300 MB unbrick images, making the claim that smaller sizes didn't seem to work. Doesn't make much sense though, as only about ~ 180 MB are needed for everything up to and including p22. (p1 - p22 are ordered contiguously in LBA address space on the SM-900V, and p23 is 2.7GB, so clearly an intact copy of /system can't be needed).
any ideas welcome

sorry to resurrect this thread, but I can't seem to find a sm-n900v debrick/unbrick img anywhere. i've found the 900T, 900A, 9005 images, but nothing for 900v.
my retail edition n900v is definitely hard bricked and I could use some assistance.

Does any one have a note 3 verizon mj7 debrick/unbrick.img

once you flash the 5.1 bootloader you can not go back to 5.0.x bootloader. i tried and got a motorola error saying mismatch. so if you flash the 5.1 bootloader that's what you're stuck on. what i want to know is, can you still flash a 5.0.x system/boot image even though you're on 5.1 bootloader?

I flashed back to stock other day after running it ..Should that have been affected

My nexus is also bricked after flash cm12 on top of the 5.2 bootloader. I hit reboot in TWRP and the phone shut down and hasn't done anything since. I cannot get anything to show on the screen and my computer is not recognizing it through fastboot or adb commands. I am running Ubuntu if that helps but again, I cannot see the device connected at all. I am starting to think I need to send this in for RMA
Any help is appreciated.

yep, in that mode we need a program that acts as QPST (or QPST itself) a 2nd_loader.hex (new bootloader) and a APQ8974_image hex that matches ours nexus 6, once there we can send the basic stuff and get rsd mode / fastboot to work, then we just flash factory images

Your best bet would be to try the Moto X/G blankflash program. It uses an executable called qboot which is a USB loader. It may be possible to use the 8226 programmer to flash the bootloader image back to the device from bulk mode. I'd doubt it'd work, but worth checking out.

Yes, you can go back to the 5.0.x system after updating to 5.1
I just flashed the ENTIRE 5.0.1 factory image, minus the bootloader.
You must obviously already be bootloader unlocked to do so.
No ill-effects whatsoever.
If you do go back to 5.0.x, make sure you flash the radio for it as well. There's a chance you'll not be able to receive calls if on LTE with 5.1's radio, as was the case for me. Only on 3g/4g did calls go through (I'm on TMO, btw)

I had the same calls issue on T-Mobile, I was on a 5.0.2 ROM and had flashed the 5.1 bootloader and radio and a friend said she called me but I didn't get a call. When she came over I had her call me again but got nothing, I could call her though. I booted to a 5.1 rom and had her call me and my phone rang.

Hey I have a fully working N6 running stock 5.1, what can I do to help?

TWRP Says There is No OS Installed and Its stuck at Reboot Loop
