[Q] Nexus 7 stuck

Hi,
my Nexus 7 (2013) is stuck on Google screen...
a few days ago I downloaded a lot of movies via utorrent, and utorrent kept crashing. So i forced stop, removed the app, reinstalled it from google play and continued.
My nexys then suddenly freezed for about 1-2mins before i shut it down via the power buttom, and since then it wont start...I've tried almost everything.
The device is stuck on Google screen. I've tried to boot it through the bootloader, recovery mode etc, but it's still stuck on the google screen. downloaded the nexus root toolkit to unlock my device, but it keeps tellin me i've to enable USB debugging. which I can't since my device won't start.
I've downloaded the SkipSoft Android tookit, but not too familiar with the tookit so haven't really tried anything yet (also not sure which android version i'm running)..
Is there ANYTHING i can do?
EDIT: tried using skipsoft android tookit to unlock bootloader, but when coming to the stage where i've to chose yes or no, the device get stuck and the power button does not respond => I can't chose Yes..
EDIT: So I've tried a few things but nothing seems to work..
downloaded a new adb+fastboot directory from another thread. Fastboot commands seems to work, but when i try and erase boot/cache etc the cmd does nothing...had this line for about 10min:
erasing 'boot'..
nothing happens.. when i unplug my device an error message shows (too many links).
so, fastboot won't erase my boot nor my cache, so i tried to fastboot flash bootloader bootloader.img, and it says my bootloader is locked.
fastboot oem lock --> bootloader is alrdy locked
fastboot oem unlock --> stuck at "YES", just as i was when trying with different toolkits.
fastboot -w update image-razor --> Error, failed to load 'img-razor'
soo i'm getting kinda desperate here...
remeber, this was all from a stock rom, no root, no custom rom, just from a freeze when dl movies from utorrent...

i have been stuck like that before. get into to the bootloader screen from where its hung at the google splash screen. once there you can fastboot a factory image.
from the google screen:
1. hold volume up, volume down and power until you get to the screen with the android and its belly open
2. connect to pc
3. download factory image from HERE
4. unzip the tar file you just downloaded and place the contents in your platform-tools folder
5. double click the file named flash-all.bat
6. wait for it to finish and it should boot up just fine.

say what? Hold vol.up, vol.down and power until i get to bootloader?
when i press vol up, vold down, and power, holding them all in together from the google screen the device shuts down..
Do you have a youtube tutorial gudie or something?
EDIT:
Also, I've never rooted or done anythign with this tablet except downloading a few apps etc...this crash happened when downloading from utorrent...

The key combination is to be used from being powered off.

Yeah, and from what i can read it also needs an unlocked bootloader, which i don't have..

just keep holding the keys down. it will shut down. keep holding it will try to boot back up and take you to the bootloader screen. you do not need an unlocked boot loader. all my nexus devices have locked bootloaders, are rooted and run custom roms.

also, should add that i tried to unlock oem via the cmd, tried to flash boot.img but nothing..
when typing fastboot oem unlock, it got stuck at "Yes" when trying to unlock bootloader, and when typing flash boot, it said error, cannot flash boot.img..
AND i'm not running a custom rom, just the standard stock rom

one step at at a time. lets get you to the bootloader screen first. all good things happen from there.

only way i can access fastboot is via volume down and powerbutton..and that's when the device is shut down

Yes, I can access bootloader (fastboot mode).
tho i don't know which version i'm running..
it's either 4.4.2 (KOT49H) or 4.4 (KRT16S).
however, when running flash-all it says "fastboot is not recognized as an internal or external command"
http://www.youtube.com/watch?v=SRfrjR9Y8fI&feature=youtu.be

dont worry about version. it does not matter. lets focus on your connection to the device. do you have ADB setup on your pc? if you dont, go to THIS thread and get minimal ADB & fatboot from shimp208. install it and run it.

Yeah, at least i think so.. downloaded the adb bundle pack..

great! have you downloaded the factory image for your device yet? get it HERE if you have not. make sure you get the right one. if your device is wifi only select that one, if it had mobile data and a sim card get the one for mobile..

Help, I know it's been asked, can't find the answer, can't boot past the LG logo

Please help, I went to update my magisk to 11.6 as it said, everything else is fine. It's rooted has NATFs ROM on it, 3.2 and everything else was otherwise fine. Then, it rebooted to install the Magisk update and here I am stuck with a phone that won't boot past the LG Life's Good screen. The screen dims slightly after the LG logo is displayed and then nothing. Absolutely nothing at all. I can't boot into recovery or bootloader, and the device isn't recognized even though my computer makes a noise as though it's connected when I plug it in to the computer's USB port.
Please help, I'm really stuck here.

Yes, thanks. I tried that. Nothing registers with the power on/volume down nor volume up.

Then unbrick the phone by going fastboot mode
Type "fastboot oem lock (or locker)"
*Then shut off the phone.
*Then do a factory reset by the same combination you do when going to recovery.
*after that try going fastboot again and unlock the oem
*with "fastboot oem unlock(or "unlocker" don't remember
Then you should be able to go to recovery.
BE AWARE : your phone my be wiped so make sure you backup.

Just wanted to say I'm on the same rom and did the update too, but I didn't have any issues thankfully.

I'm a moron. Can I ask for really stupid steps here because I'm kind of nervous about making this worse.
1. I was able to oem lock and unlock, however I still can't get past the LG screen. I can get to fastboot, nothing more
2. I'm sure everything is wiped, I'll worry about later, I just want to be able to get to recovery and nothing is registering at all
3. ADB reboot recovery isn't working at all I get error: device '(null)' not found
Currently, I'm sitting with the device plugged into my computer on fastboot mode displayed on the screen with the command "use fastboot reboot" if the fastboot is available.
fastboot devices shows the following:
LGH918ad448f8 fastboot
Is there a way to get to recovery from fastboot?
ugh, this is so frustrating. Any help would be gratefully appreciated.

After you locked the oem. Did you turn off the phone and then factory reset (by pressing volume down and power, after you see lg you then release only power button for a second and press it again)?
Make sure to do this after locking oem and before unlocking oem.

Alright you can theoretically flash the recovery twrp.img through fast boot, after you reflash the recovery you can go recovery from there.
I think typing fastboot reboot recovery
Check online. I'm not sure exactly.

After you do that button combinations it's going to ask you if you want to wipe or factory reset etc, you choose YES twice!. If you flashed recovery before then it'll take you over there after the choosing yes (it's not really gonna do anything just suppose to take you to recovery)
Edit: Okay let me be clear. When you lock the oem you should do the buttons combination. If you do them successfully then it should take you to a white screen. Asking you about confirmation twice. Then it will wipe and factory reset.
Now when you already have oem unlocked, you do the same procedure and which will take you to white screen then you choose YES twice then it'll take you to recovery (if you have successfully flashed it before)

Lol, btw it's volume DOWN not volume up.
So don't even lock the oem, try doing the combination properly now
Edit: so if it still doesn't work then try flashing twrp.img through fastboot there is a command I just don't remember. Make sure you have the .img twrp file locally so you can flash it.

i did choose yes twice, but when exactly did I flash recovery at this point? You write "IF you flashed recovery" I had recovery on here already but can't get to it
at this point, all I can do is see fastboot if I plug the phone into a cable, put the battery in and hold the volume down button down otherwise, I can't get to anything else but fastboot.
I'm at the fastboot mode
I downloaded the latest recovery twrp-3.0.2-1-h918.img (renamed to image.img), I'm trying the following command to push and flash recovery through bootloader but I get the following error
message:
fastboot flash image.img and I see the following error message:
cannot determine image filename for 'image.img'
What am i doing wrong?
ugh, I'm really sorry for asking so many dumb questions

The proper command is;
Fasboot flash recovery image.img
And make sure the twrp file is stored locally from where you started the command prompt.
If it worked and flashed then try: Fasboot reboot recovery
To go to recovery.

I was able to run the following command from fastboot (looked it up):
fastboot flash recovery image.img
I see the following error message:
target reported max download size of 5368...

So, should I try the volume down and power button again?

Ugh, thank you so much for your patience. I did the following:
battery pull
power on, volume down
LG logo finger off for one second on the power button, kept volume down
rebooted into recovery, I'm flashing NATF ROM now
thank you so much I hope this works, all the data and stuff can be recovered, didn't/wouldn't lose much, all backed up. It's installing now.
i sure hope this works
YES, I SEE THE ANDROID boot screen. This thing takes a while to get past but at least it means I'm on the right track.
I thank you a lot brother.

I do a daily backup at about 3am to my SD card. Thought about restoring from it, but then realized this is an opportunity to start all over which is something I was leery to do because I didn't want to set the phone up again. Yet, I'm doing it now to see what was causing the awful battery drain.

MI A1 Fastboot

MI A1 does not enter the fastboot, appears the message "your dvice software cant'be checked for corruption, please lock the bootloader" Two things, first I am layman, I understand little, the other and excuse the translation, was machine translation.

The message has nothing to do with the Fastboot. That message is a normal reaction when the bootloader is unlocked.

If I hold on, the same thing will happen 10, 20, 50 times, I've already tested it.
If I release the volume - and power buttons, the unit comes in and I have to turn it off to try again :crying:

Can you boot into the system at all? Does the phone work? How did you get to the point that you can't enter Fastboot, what happened exactly?

Good question, did not offend me. I figured it was time to start learning about it, I was thinking of installing the Google Pixel rom

With the phone OFF:
Press Vol- and Power, when Bootloader screen appear just release the power button, so continue to hold Vol- until the fastboot screen.
It's the only procedure for fastboot on our device.

It did not work, the error message appeared and as soon as I released the power button, came on the device. This problem has left many people without understanding, I just did not give up, because I do not accept that only my cell phone this function does not work

Does your phone have root? If so you can use a reboot app from the play store to boot into fastboot.

Install adb drivers, enable USB debug then open command prompt and type "adb reboot bootloader". Phone should reboot to fastboot mode.

adb reboot bootloader worked kkkk now that the fastboot worked I will solve if I try to put the other rom, or if I leave as is, but if any of you are where I find information on how to change the rom and if it is really worth it, me Please, thank you very much at all

Stuck in Boot Loop

Have searched the forum but came up empty.
Hoping someone can help.
Purchased the phone used back in December and have been using it as-is. Two OTA updates came through fine. The latest OTA update has it stuck in a boot loop.
- I can get to fastboot with power and volume down buttons but all of the options either turn it off or stick it back in the loop again (Essential logo with powered by Android, NO dot animation)
- Can't see it via "adb devices" since developer mode was likely not enabled
- "fastboot devices" can see the phone but can't change slots or do anything else
I saw two other people who've posted something similar but no solution. Is my phone garbage?
Any help is appreciated.

Damn, that's a bit unlucky, this March update said it would make recovery from a loop after OTA update easier to recover from, which might just have helped you. Sorry not sure how to help fix at present.

A couple of questions:
- Is your BL unlocked (or is OEM Unlocking enabled)?
What happens if you try executing "fastboot flashing unlock"? NOTE: this would WIPE your data if successful.
- Can you get to the Recovery mode? It's when you pick "Recovery" option from fastboot mode, see the lying android with an exclamation sign, then hold Power and press VolumeUp to get to the Recovery menu.

Thanks for your response.
- I dont belive OEM unlocking is enabled.
- I can get to the fastboot menu, but the recovery mode option just takes me back to the 'powered by android' logo, not the green dead robot.
- When I try fastboot flashing unlock, I get the below error:

Dang... :\ Yeah, the last error means you don't have OEM unlock enabled. So, you can't flash the bts image via fastboot. One last thing I could think of is trying to get to recovery by the button combo. Although, if you are correct in saying you don't have USB debug enabled, it won't do much good, i.e. you won't be able to flash an OTA... :\
While device is OFF, press and hold Volume-Up button while pushing Power button to boot.
Your device will now be in Recovery mode. An Android logo with red exclamation mark should appear on screen. Hold the Power button, then press the Volume-Up button one time to see the recovery menu.

can you try this command on bootloader:
fastboot OEM unlock

Well, I did it this time.
In a valiant attempt to install a custom ROM, I erased every partition using fastboot,
Code:
fastboot erase system
fastboot erase boot
fastboot erase userdata
fastboot erase recovery
fastboot erase cache
Now what I meant to do here was flash a recovery, using
Code:
//fastboot flash recovery TWRP.img
but repeating this so many times over the last 48 hours, I did not do above and instead went quickly right into below,
Code:
fastboot reboot
The system rebooted as I told it to ... right into a black void of nothing. Now their is no 'recovery' image and no 'bootloader' image ... the phone is hard bricked, won't turn on at all, dead. I was so close to getting to the custom ROM! Is there any chance to get it back into recovery mode? or have I learned a $350 lesson?
Edit: Further research indicates it may be possible to force the system into fastboot using a USB jig. Has anyone tried this method?

When you plug it in while holding volume up what happens?

Nothing. LED flashes red every few seconds. The same response if plugging it in without holding volume up. Along these same lines, holding the power button on for a few seconds causes the small vibration haptic feedback to occur as if it is turning on normally ... but nothing happens the phone remains dead. Similarly, holding volume down and the power key causes a small vibration haptic feedback as it was booting into recovery ... but nothing happens the phone remains dead. I haven't seen anything on the screen appear, or the phone turn on it any way, since executing the fastboot sequence previously described.

Whatever you did, you should still be able to enter in flash mode and flash a stock firmware. And by this I mean full stock firmware, not a ROM.

Ok, that would be great. I would be thrilled to get the stock ROM back, at this point getting the phone to turn on at all would be a victory! Would you please describe precisely how to do enter flash mode with the phone in the current state? To reiterate, the phone will not turn on in any way (normally, or volume down + power to boot into recovery). The only life in the device is a slow blinking red LED when it's plugged in, and a quick vibration after holding the power button. The screen has not turned on in any way, or the LED shown any color other than red, since executing the fastboot sequence previously described.

hold power button + volume up and to force shutdown
and then hold volume up (or down, i don't quite remember) while connecting it to a pc (hold the button while connecting the usb cable).
If the led turns green or blue, congrats

The power key has nothing to do in this context. It is used only to boot into recovery or force OFF.
While holding VOL ↑, plug the USB cable to your PC to enter into fastboot mode (blue light)
While holding VOL ↓, plug the USB cable to your PC to enter into flash mode (green light, or maybe nothing)

Nothing. Device still unresponsive as described.

does your PC detect the device ? (new device sound notification)

No, the PC does not currently detect the device. All drivers are correctly installed as the phone was recognized accurately prior to the described fastboot sequence.

This is weird. I already erased everyting via fastboot too a while ago, and I could still flash it.
Just to be sure.... unplug all other "smart device" before anything (drivers can't handle more than one device at a time when it comes to FB or flash mode). Open the device manager and let it to the foreground. While you hold the vol down key, plug it and keep holding it until the device is detected. Don't expect any reaction on phone's screen, it remains OFF in both fastboot and flash mode. So, if the device manager reacts, you win.

I'm getting something here which is very encouraging! Executing your sequence causes the device manager to blink (refresh) as if it sees something, however no new devices are recognized in the tree. The phone LED goes to a solid green, reminiscent of a fully charged battery, stays on for about 30 seconds, briefly blinks red and then back to green, etc. The device manager is certainly reacting here it just doesn't recognize the device.

So here we are, you win. Because you have the "two", detection and green led. And if this state goes off after a certain time, it is normal. There is a kind of countdown and the device quits that mode if nothing is sent to it. You should be able to flash a firmware now with flashtool software.
Just ensure you have proper drivers installed properly (WinUSB drivers need to turn signature verification OFF before or Windows will block the installation)

Unbelievable! You saved me! I'm back up with the stock ROM and peace of mind to attempt the custom ROM process again. Saved me $350 ... thank you!!

That's great : )
It is almost impossible to hard brick a Xperia. If something goes wrong, remember flashtool ^^
