Formatted storage to f2fs and now can't mount anything - Nexus 7 Q&A, Help & Troubleshooting

So i messed up badly...
Really badly...
I finally unbricked my Nexus 7 with the help of nvflash.
Had trouble with mounting /system.
Fixed it.
Locked Bootloader in process of fixing.
Didn't find a solution.
Tried to flash a new ROM.
Formated data, cache and system as f2fs.
Installed ROM from TWRP.
Got message it succeeded.
Rebooted.
No ROM.
So back into recovery.
New problem:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I can't load any partition at all.
Can't fix them.
Can't wipe them.
Can't format them.
Tried to reset everything by flashing the blob files again with nvflash.
Finally unlocked the bootloader with this.
But still no storage.
Even internal storage is shown as 0mb.
I fixed the system problem before by using this:
Code:
cat /etc /fstab
make_ext4fs /dev/block/<insert id of system block from fstab here>
But I don't have any of those blocks remaining. So I can't reference anything here.
I guess I have to format the whole drive somehow and repartition it. But I don't know how to do that.
I would really appreciate the help.
I got so far and always do something dumb to create a new problem
EDIT:
Also I just had a look into the filesystem with twrp and I guess I really need to build everything from the ground up. There should be a few more blocks and partitions :/
EDIT 2:
If anyone can run the following 2 commands on a 16GB Nexus 7 and post the output I can try to create the partitions with parted. Would really appreciate it
Code:
cat /proc/partitions
cat /etc/fstab
and if you have parted then
Code:
/parted block/mmcblk0
(parted) p

(Solved) [I9000 Int] Forgot to disable Voodoo before Odin Flash (Soft Bricked)

I9000 International
I can't delete this thread so I'm just editing it and leaving it for reference
My Problem:
I forgot to disable voodoo.
I then tried to install another kernel/rom via CWM and it soft bricked.
I then tried to flash my stock firmware via Odin and it would just fail at factoryfs and i can see in CWM + ADB it would not mount /system and /cache,
When CWM started it would say can't "mount /system or /cache" or can't mount stl11"
I see no /system in ADB
I can see my /data is still in ext4

superCurio's guide @ http://project-voodoo.org/documentation
If you forgot to read this giant documentation and installed another Kernel or Firmware without disabling lagfix first, well… that’s too bad, but it’s repairable by 2 options:
* Re-installing Voodoo by flashing the Kernel with Odin: Your ext4 data will be back if the previous procedure didn’t format DATA partition
* Starting into recovery and wipe data. Warning, like it says, you’ll loose your personal data. If you don’t have backup, use this option in last resort.
If you need to disable it without having access to your screen (ex: screen broken, you need to send it back to a repair center) here is what you need to do:
adb shell ">/sdcard/Voodoo/disable-lagfix"
I will also suggest that you revert to the original stock firmware before sending it back.

Have you bought it? Like from a store or something?
Have a look at this:

Quote from article with fixes for A5:
Solution
This data is in persist partition in samsung phone named (persdata) of the phone so you need to format it to fix your phone. But to format this partition you need access to "adb shell" to communicate with phone.
1. First of all find latest CWM/PHILZTOUCH/TWRP recovery for your phone and flash it using odin.
2. Boot you phone in you custom recovery and connect the cable make sure its detected as adb device in you device manager to confirm you can also run the command in CMD ''adb device"
3. Now you are ready to format your persist partition.
adb shell
mke2fs /dev/block/platform/7824900.sdhci/by-name/persdata
dd if=/dev/zero of=/dev/block/platform/7824900.sdhci/by-name/persdata
exit
And the final step is to Wipe Dalvik & data / factory reset. Its always recommended to flash phone with other firmware then EE uk region firmware so that this will never come back.
Please note, I did not come up with this solution. I only copy and pasted it and changed the folder the persdata is in
If you have ROOT + Xposed through the app, imei changer change all your data and bypass the restrictions.

[Q] Error validating footer No VBMETA

My friend's phone had an update recently.
The update finished perfectly but after a while the phone shut down and when she turned it back on it showed this screen:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
"Recovery: Error validating footer.
No VBMETA
VBMETA ."
The phone shutdown after a few hours and it's not turning back on whatsoever
I don't want the internal storage to be wiped so i found a way using Home_CSC but i can't find a ROM with my carrier (i live in Syria) + the phone isn't turning on anymore.
Is there any way to fix this without losing my internal storage?
If wiping the internal storage is the only way please tell me how to fix it too.
Thanks in advance! and really sorry if this isn't the right place to post this i really have read the noobs guide.
