[Bricked] Nexus 7 2012 WiFi Bricked ? - Nexus 7 Q&A, Help & Troubleshooting

I accidently wiped Internal storage completely using TWRP now my tablet showing OS not installed and stuck at GOOGLE logo screen .. How to get in to recovery mode from this stucked screen ? ;(

Hello,
I have completely wiped my device the same way as you did and I did not brick mine so you should be okay. See if the following helps:
1. Hold down the power until it turns off.
2. While holding down the volume down, turn the device on which should take u to your device loader
3. Push down until u see recovery
4. Press the power button and u should be twrp.

If you can get the tablet into fastboot you will be alright. Reboot the holding the volume down button, then reflash the stock image.

I have the same problem with my Nexus 7 2012 version. I can get into TWRP but I can't get it to recognize my USB stick where I have an image of the latest android OS for the Nexus 7 2012 32G version. My bootloader is locked. I accidentaly erased it. Dont even remember if I had usb debugging on or off? It does power up and charge properly, and yes I am using an OTG USB adapter cable.....Help...

Pumping, because I have the same problem as va7lfd

[Q] How to reboot into recovery?

If you get stuck in a boot loop, is it really the only way, is to hook the n7 up to a pc? It's not exactly like you can pull the battery....

long pressing(10-20 seconds) the power button will reboot the device. if you also press and hold the volume down button when it reboots, it'll take you into the bootloader. from the bootloader, press the recovery option.

update your bootloader. you should be able to get into your recovery with the recovery option if you connect your device via usb to your computer.

I tried connecting the device to my computer via USB before selecting recovery. When I do that, volume up/down and power do nothing! So I have to reboot by holding power again. What do you think now?
I didn't realize I had to update the bootloader I was in the process of updating my ROM from SmoothROM 4.1.2 to Modaco 4.2 and it did not flash properly. So at this point, I cannot boot up. I'm stuck here.

Ok thanks for the reply.... But I'm not sure how to boot into recovery now that I'm running stock
Turn off your phone, boot in fastboot mode (vol up, down and power button), move to recovery with volume buttons and press power then press vol up and power for some second and you should see options

When you hold these two buttons and you see the LG logo, release and hold them again fast until you see factory reset screen. At this point press the power key three times and you will go to recovery. An press the thanks button here.

I think you have have to hold for 5 seconds to completely power down.
Hold vol- and power key and when logo pops up release power key and again hold power key then Reset screen should display. Press power until it starts factory reset which will dump you into Recovery.

No with no rom it will probably just sit on the LG logo or something
Have you tried this?

i had to get ADB on my device to root and put CM there in the first place, not sure why its not working now... maybe because USB debug isnt checked? i have no clue.
all i need are drivers right? is there a good link for re-setting that up

my adb works fine even with no rom

http://www.lg.com/us/support-mobile/lg-D801 scroll down and download... the driver should work fine even though its d801

Which phone? Asking for help with zero info on what you're using and what you've done isn't likely to illicit much.
Just do a full reset (from power on) and then flash stock kdz.

I feel bad for you but hope you've learn a lesson, read more and more and more before doing anything to your phone. If you don't know or not sure or unclear, don't go for it yet.
Anyway, still under warranty?

To switch off your phone. Hold the power button about 10 second. you will see screen completely black, or unplug your battery.
To do hardware reset for F320L. Press and hold power+ volume-, when LG logo appear release power button only and press power again. You can see Hard reset mode.
After that, if your phone still not reboot. Try to flash KDZ or TOT in download mode.
To access download mode : Press volume- and plug your phone to PC
If you can not access download mode. plug your phone to computer and check what driver you have in device manager. If you got only Qusb-Bulk. Its bricked completely.
If you plug your phone to Windows and got a lot of message come up to format it. press cancel and don't format it. then follow :http://forum.xda-developers.com/showthread.php?t=2582142

when l'm using VRoot app ad ex....this app recognized my device lg g2 f320L , but the software is from F320s..so this avoid warranty...solution is to change the motherboard...but it is 250 fuc''g euros
Can you use adb to push file into /system folder ?
This is the only way to replace your build.prop file to change F320s to F320L
Well I am a bit confused... mostly because this isn't so clear...
When you hold power button it reboots, but if you continue to hold it, it will shut itself down.
It's this way on LG G2 D802 and should be the same on yours.
When it's shut down, hold volume down and then power, when you see the LG Logo release the buttons and hold again volume down and power button. This should get you to recovery...
Try it like this?
I play around with my G2 alot and I have had the LG logo issue several times.
I use PhilZ Touch Recovery and TWRP to backup valuable files.
PhilZ Recovery with AROMA File Manager and if that isn't set up I use TWRP Recovery.
You need a USB OTG connector for this...

Try this for getting to download mode it worked for me:
1.) don't push any buttons, just plug phone into computer using usb cable
2.) push and hold power button + volume up button
3.) do not let go when you see LG logo, continue holding
4.) after a few seconds you should be in download mode

i hold power button, if phone isn't connected to pc he is going off. Think is because battery is very low, led is blinking in red.
Then I hold vol down and connect usb cable, but how u can see on video phone weak up and go to booting.
I have hi suit last night as i mention fastboot works, but need to unlock phone. After that "your devices" screen came out and can't fastboot anymore
When i turning off phone with connected usb i can't turn phone off. After a second phone power on by his own.
If phone is disconnected longer than 5 min, then i push vol down and connect usb only red lightening shows up. I need to wait a while to phone start.

OK. When phone is off, if you connect with PC, phone should be start, but this is only for charging. May be, you don't have charge, so phone is not going to fastboot mode with vol down?
Now just connect the phone with PC for full charge.
You don't have any recovery? Custom or stock?
It can be happen?

When i start charge phone blinking red in led, after while phone vibe 1 time and go to booting now, but led don't stop blinking. I will try to charge it, but because of working screen, phone heat a lot i don't wanna burn it.
Before i made rollback and something gone very bad, emui update after 100 % phone don't boot up. Without usb cable i wasn't able to go recovery or fastboot. So i think i don't have any recovery i made backup of files with twrp but now i can't flash it.
after night without power, phone drain all of battery. Now i understood better what is going on. when i plugged usb cable, phone don't start bye it own, only red lighting flash for second .
I disconnect cable and connect it with vol down button how all of here wrote. Phone immediately weak up an go to "your device has been..".
It's look like after i unlock phone (bootloader) somehow i was able to corrupt bootloader files or even delete it. Some one can confirm that it is possible to crash bootloader ?

Every time I disconnect the charger, and reconnect it starts from 0. I read some other people here have the same problem. Send it to warranty and explain your rollback process unlocked the bootloader somehow (I mean the phone does do a lot of sh*ty sh*t, so this shouldn't seem very odd as well!!!) and hope that you get a repair/replacement and after that sell it on ebay hoping some stupid people like us in the first place will buy it and spend your money on a phone more reliable!
I managed to access the fastboot using the 3 button method in cold boot. Hold the Power key until the screen goes off and then release and hold down the Vol- key and immideately connect the usb cable to PC right before it vibrates or exactly when it vibrates (it's a matter of timing), and bingo you are in fastboot and you can flash system.img, recovery.img, cust.img, cache.img and boot.img from there, but this is not how I revived my phone. I used the 3 button method again when the phone was charged for like half an hour or so and the did the same cold boot trick and I could boot into the force upgrade environment (strangely this still didn't work whitout connecting the usb cable to PC), but it somehow didn't want to read the UPDATE.APP that I had in dload folder on my SD card and wanted to have it from my PC (I just felt it nad there was no indication of it ) so then I installed the DC Phoenix tool and payed 15 euros to be able to inject the complete UPDATE.APP to my bricked phone and the installation went well to 99% and failed, but I rebooted the phone and I could boot normally. Just to make sure I did a factory reset afterwards. Hope this helps.

Yes. I am actually writing this from my Huawei P9 Lite now. This phone is really a nightmare for modifying and customization. I'm not sure if I'm going to resell it or just wait a reasonable amount of time until some reviews from the next update come out and see if I might wanna take the risk and update my phone again.
