Stuck at Google logo after update

I just got my Nexus 7 an hour ago, once i setup with my google account then it asked me to install an update (apparently it says 4.3 update) so I let it do its job and left it there. Now it's stuck on Google logo for quite some time. This is weird for me since I didn't root or flash anything to it yet. Anyone facing the same problem?
EDIT: apparently it got to the X screen after i hold the power button and turn it on again. this is strange...the update shouldnt cause something like this to scare new users lol.

Hold down the power button 30-60 seconds until it reboots again. See if it goes through.
If not, boot into recovery and factory reset.
Power down tablet, Power+VolUp until you see Google, release buttons.
You'll see fallen android, in this exact sequence, Press and Hold Power, then press/release VolUp, then release Power.
You'll see a menu, press VolDown to scroll to wipe data factory reset. Press Power to select.
When it is done, Reboot should be selected, Press Power to select reboot.

unluckily, I can not hard reset by pressing volume down and power
DO U have another method?
thanks!

for hard reset on stock cwm : turn phone off. press vol up + vol down + power.

I had the same problem. I even got worse and the phone wouldn't even turn on. So what worked for me is this:
I put the phone in download mode (Vol Up + Vol Down and then plug the usb)
After that I open LG Mobile Support tool. http://csmg.lgmobile.com:9002/client/app/B2CAppSetup.exe
Wait for the program to detect the phone then go to Options-> Upgrade Recovery. Wait for the process to finish.
After it finished the phone loaded normally and everything was intact. All my files and apps were untouched.

1. Unplug phone - VERY important
2. power on phone, doesn't matter if it is boot looping or whatever
3. hold vol up and power EXACTLY 10 seconds
4. let go of both
5. hold vol down and power till boot loader comes up.
You have no charge because you are running an old ver of twrp, get 2.7.1.0

Share how I fixed my HTC M8 with the same problem.
Hi,
I just want to share how I fixed my HTC M8 with the same issue. The method is the same but a bit different. I found the solution from googling the below link:
http://forum.xda-developers.com/htc...ter-download-mode-t2853100/page2#post62490577
The essential method is to keep holding down the power button and don't let it go while pressing on the volume up button to reset. At the very moment before the phone resets and shows the HTC logo white screen, switch from pressing the volume up button to the volume down button while holding down the power button. Or you can count 10 seconds and switch before the screen resets.
I hope this helps other people with the same issue.

Thanks, the pwr + vol-up 10 seconds before the phone hard resets, them pwr + vol-down got me back into hboot and recovery and then out of a build.prop issue.
I have no idea why this is a thing: Getting into the boot loader is usually easy. I can't imagine why when the system doesn't boot normally that the standard procedure to enter hboot changes.
regardless of retarded engineering on qualcom or htc's part, thank you an0ther.

Shut the phone down. then remove the battery and wait 20 seconds and reinsert it. Then try to get into recovery (look here for how to http://www.android.gs/enter-recovery-mode-lg-g3/) mode and see if the phone is recognised by the computer if you connect it. Then do a data factory reset in recovery.
Turn off your phone – you can press power button once for selecting “power off” or you can press and hold the power key for about 5 or 6 seconds.
Now, press and hold Power and Volume down buttons at the same time.
When the LG logo appears, release the keys.
Immediately press Power and Volume Down buttons again until the Hard Reset menu will be displayed.
Press Power button once and confirm the hard reset operation (this will not be necessarily if your LG G3 is running on a custom recovery image).
That’s it; now your LG G3 will boot into recovery mode.

How to reliably start TWRP

I have TWRP installed, and have managed to run it a few times. Now I cannot start TWRP at all.
From off, if I switch on, the following happens:
1) Screen with Samsung Galaxy A70 - Secured by Knox
2) 0.5 seconds later another screen, "this phone's bootloader is unlocked and it software integrity. .." and "press power key to continue..."
3) 5 seconds later, same screen as (1)
4) 3 seconds later, red letters "this phone is not running Samsung's official software"
5) 3 seconds later blank screen with "samsung" and then booting to android.

In my experience I have to flash twrp every time I want to use it( I don't know the reason but I couldn't fix it ) , for booting twrp on the other hand I turn off the phone first, then I press power button+volume down until the "this phones bootloader..." screen appears, here is the tricky part, you have to quickly let go of these two buttons, press power button, let go of the power button (after the warning disappeared) and then press volume down button (and hold it) until twrp logo appears, this happens really fast so you may need to do it a few times to get used to it.

Yes, same here, the only time I have managed to run TWRP on this phone, is right after a flash.

Power off the device, plug into a pc, wait for it to start charge, hold vol up and power till it turns on. Wala boots to twrp. If you have magisk installed,you can use the reboot option within magisk.

Samsung changed how to enter recovery on Android 11. Power off device, plug into pc, wait for it to charge, then hold vol up and power till it turns on. Alternatively, if you have magisk installed, use the reboot options within magisk.

I did that. Thanks!
But it has gone to:
Android Recovery
Samsung /a70qxx/a70q
11/RP1A.200720.012./A705FNXXUB5DVB3
user/release-keys
Use volume up/down and power.
Reboot system now
Reboot to bootloader
Apply update from ADB
Apply update from SD card
Wipe date/factory reset
...
...
...
Where is TWRP? It seems it's gone.

That's because you're not installing it properly go back to my guide and follow it exactly and stop listening to these other people. I've been modding this device since it first came out with Android 9, I know every inch of this device. You're getting confused by what other people are telling you

It fails here, on this step. After successful flash of recovery.tar, power + vol down to reboot, cable still connected, nothing you can do now can bring TWRP up. The phone boots into Android.
EDIT: I think I have now got it. I will update in a few mins.

After successful flash of recovery.tar, power and vol down to reboot, as soon as the phone screen goes blank, immediately release all keys and press and hold vol up. Must be as soon as screen goes blank. The device will then reboot twice and land you in twrp splash screen. You must hit vol down and power after successful flash then when screen blanks, vol up. If you miss this step, twrp will not hold and revert back to stock recovery.

Here is the notes I made today:
****************************************************************
INSTALL + START TWRP
phone is off
press up + dn
insert cable
go into download (press up)
ODIN 3.14 + AP:tar(vbmeta.img+twrp.img), auto reboot off, press upload
when it succeeds, press dn + pwr until it reboots
then quickly up + pwr until it starts (no need to hold down)
this starts in TWRP
from powered off
press pwr button
goes into twrp or android(system) -- depending on what was used last time
if we used reboot->system last time it will now **Always** go into system!
to go back into twrp:
switch off
power cable until charge
pwr + up until it starts
****************************************************************
The above means that you CANNOT go back to TWRP unless you have a cable and a PC near by.
