[Q] Nexus 7 bricked & unable to flash

Hi everyone, first I have to say that English is not my primary language so I apologize for any inconvenience.
So what stupid things I did was, I used Nexus Toolkit to upgrade to 4.4 Kitkat from a Custom ROM and Custom Kernel
After I realized it, i wasn't able to boot up the device properly
neither the Android itself nor the Recovery
All of it will show up a line of word "Booting Failed" on the top the bootloader screen
I tried to recover it to stock using Nexus Toolkit but sadly it started to fail after those erasing command
(Even using the flash-all.bat)
Now the device is still can be found by using fastboot devices
And I tried to flash CWM and gives out the error output :
{
"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"
}
What can I do now ?
Helps is much appreciated
SOLVED
After booting to temporary recovery, I found that the only problem is that the internal storage is unable to mount
So after wiping every thing and format I managed to flash recovery and system too now

Twrp E: could not mount

Hi people.
I from Chile and sorry if I have bad english.
I bought an LG G2 D805
The problem is that the device came wrong flashed.
They wanted to put Lollipop and caused a brick.
When you turn on the device immediately get the recovery TWRP with the following
{
"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"
}
When I connect the device to the computer in recovery mode I can not use the MTP for the same reason as shown in the image.
In the recovery, selecting the install mode, appears in storage: internal storage (0)
I can enter the download mode (bootloader) so even I have hopes of saving the device.
I used various tutorials to fix the device and none has worked.
I used the method with LG Launcher .. and nothing
with flashtool, various methods (kdz and TOT) ... and nothing
I used ubuntu but recognizes it as computed Lg G802 and that caught my attention.
I think I can not fix the device while the recovery not moutn the data.
never before he had had problems following their tutorials but I have not found a solution for this problem and I need your help.
THANKS IN ADVANCE

How to recover from factory reset on TWRP

Hi
I had an open stock firmware on my LG G6. Unfortunetly I made factory reset as the phone was crashing apps.
Now the phone will boot into TWRP but flashing any of the firmwares is a failure.
First it was unable to unmount /system so i switched it to ext3 and back to ext4. Now the flash ends with result 1.0000 and after reboot im still in TWRP.
I can enter TWRP or start recovery with Vol Up, however in recovery it says with red MODIFIED / E / L / R0 / id :0 ()
I tried using LG UP but im stuck on this and none of the dll's seem to work for me.

How to proceed to unbrick it ?
None of the dll's worked for me. I've let this rest for a few days and then stupidly found solution when searching for an answer, some info that installing LG Bridge might solve the dll issue.
It appeared that there is a magic button which recovers all phone with one click on Recovery within LG Bridge software.
Just a question. Is it now safe to lock the boot loader so I can run android pay?

Fastboot is not working but adb is fine.

Hello everyone. I have my asus zenfone max pro m1 and I want to install a custom rom in it, which requires me to go to fastboot.
I have followed a post on xda forum about it.
I have unlocked my bootloader.
installed adb and fastboot (platform tools).
enabled usb debugging and allowed my pc.
Now when give the command for adb devices, it shows me the attached device. Then i give the command "adb reboot bootloader" and it works perfectly and I enter fastboot on my device.
But as soon I give command fastboot devices the fastboot menu in my phone changes to small font saying "press power button to shutdown" . But when I restart my PC and do it all again, the first time when I
give the command for fastboot devices it shows me my device , but second time onwards it shows "??????? fastboot" and again the same small font message is shown. I have attached screenshot of my CMD for better illustration. Please help me regarding this . Thank you.

Flashing with ODIN problem.

Hi guys, i've bought note 20 ultra recently, i have to flash stock rom to my note fan edition phone but there is a problem.
I've tried several versions of odin in order to flash but no luck.
I had floydq v6.0 before, now phone doesnt even booting it says only "official released binaries are allowed"
Here is my steps:
- I downloaded binaries for N935F from sammobile,
- Tried to flash but no luck it stucks at SetupConnection or NAND Write Start or Set Partition part
- Then i came across with a thread that says i have to enable OEM Unlock but the thing is i couldnt see that switch in my developer settings page, i tried several things
- Now i am trying oem-unlock with fastboot but the thing is fastboot does not recognize my phone, but before the brick adb could see my phone idk what am i doing wrong
- I think i successfully installed the right drivers such as (Google Driver, Samsung OEM driver)

Can anyone help me about that problem?
Using odin v3.13.1 solved my problem.
