So, I was using my Nexus during my class today and it was working great.
After class, I walked to my next class with the tablet in my hand, I did not drop it or anything, when I got to my next class the lock screen was unresponsive.
I was still able to take a screen shot, so the tablet wasn't frozen, but the touch screen was not working at all. All of the hardware buttons worked fine.
I let it sit for about 2 hours and the problem persisted.
I just did a soft reset, holding the power button down for 10 seconds, and it shutdown and rebooted, but its now stuck on the Google screen.
Anyone know what is wrong or how I can fix it?
Thank you

Have you tried entering bootloader?
[Info] Guide to entering safe mode, bootloader, stock recovery
I really doubt you are in bricked mode or it wouldn't even show google. If it is stuck on google it is having trouble loading the OS.
Most likely you can go into fastboot mode and just flash your /system and it will begin working again with no loss of data.

My problem is I can't turn the tablet off. When I hold the power button it just restarts.
Also I tried the hard reset and it does nothing. Just stays on the Google screen
Is your device rooted? If not that is just rediculous on asus's part

My device is not rooted at all.
I've had it for 2 days.
I have to say, I am very disappointed in all of these issues.
I would return it..I'm sorry to hear that I have had troubles myself with two devices so far

Did you specifically try to get into bootloader mode using the post I mentioned.
You need to Press Power+VolDown continuously until the bootloader menu comes up?
The fact that you are getting to the Google screen at all means your bootloader is still working so I find it hard to understand why you wouldn't be able to get into bootloader mode.

It was not working, but my tablet just died and I was able to charge and get into the bootloader.
Now to see if it will work.

Well since you are getting stuck on Google, that means your ROM (/system) is not loading.
I would flash boot.img and system.img from the factory restore.
http://developers.google.com/android/nexus/images#razor
The restore is in .tar.gz format and within the tar there is a zip file. Within that zip file is boot.img and system.img. You need to extract those (ungzip, then untar, then unzip) and place them in your adb directory.
Boot your tablet into bootloader mode, connect the USB cable, make sure it is recognized as android bootloader interface.
Type
fastboot flash boot boot.img
fastboot flash system system.img
assuming no errors
fastboot reboot
If on the reboot you still get stuck, push and hold Power for 30-60 seconds and try again.
Fails a second time, something more serious is probably wrong.
If you get stuck on X instead of Google, that means something may be wrong with your user data. Try the 60 second reboot thing again. If it is still stuck on X, boot into recovery and do a wipe data factory reset. See previous post for how to get into recovery.

I figured out where to type, but I have to unlock my bootloader?
I have no way to enable usb debugging since I cant tun on the device, right?

You don't need to enable USB debugging for fastboot mode.
You just need to press Power+VolDown until you get into the bootloader. That is fastboot mode. It will install Android Bootloader Interface (usb debugging does android debug bridge interface)
I actually didn't realize you weren't unlocked. If that is the case, the unlock process will erase your userdata, so you might as well just do the full factory restore.
First goto bootloader mode using Power+VolDown and connect USB, type
fastboot oem unlock
You'll see a question on the tablet screen, Press VolUp to go to yes and Power to select.
On the command prompt in windows, you should see it erase userdata and cache.
On the bootloader screen it should have "Start" highlighted (if not, use VolDown to cycle until you see "Start"). Press Power to accept. You should see Google, then it'll go into recovery and format userdata and cache. It'll then try to boot and since /system is having issues, you'll be stuck in Google again.
Go back into bootloader mode, hold Power+VolDown for a while until you see the bootloader screen.
Now grab the factory image as above, gunzip, untar, and you should have a folder razor-jss15j
Copy these files from your adb directory to the razor-jss15j directory
adb.exe
fastboot.exe
AdbWinApi.dll
AdbWinUsbApi.dll
In command prompt in the razor-jss15j directory, type
flash-all
It should output a bunch of stuff, essentially writing a factory image to your tablet.
When it is done, it'll reboot and hopefully you'll get the initial setup window.
I wrote this up from memory, so hopefully I didn't forget stuff. If something doesn't seem right just ask.
Thanks for all of your help.
It really means a lot you took the time to help me.
I'm going to Best Buy today and I am going to see if I can do an exchange.
If not, I will try this later.
Again, thank you
So here's the deal, I tried to format the cache partition of a stock, non-rooted and non-unlocked bootloader Zenfone 2 (Z00A) through recovery, and it somehow failed/got stuck. After about 1h, I shut down the phone via long-pressing the power button and now it won't boot.
Booting it just leads to an "error!' message and stay there. Trying to go back to recovery does the same thing, I can get to the initial fastboot screen, but selecting recovery mode and pressing power+vol up after the reboot doesn't lead to recovery at all. Instead, every 5 or 10 seconds, the screen clears to black for 1 sec and the same error message shows up.
I tried to get access to it through ADB, but it won't show up in the device list under either the fastboot screen or the Error! message screen on which it stays stuck. Also, the phone was setup so that it didn't allow USB debugging, but I doubt that matters, given that it can't even load Android at all.
Is there something I can do about it? Any tip is greatly appreciated, I looked around XDA and Reddit but didn't find anything that really helped.
When you get to the Error screen, hold power and press up volume button. It should get you to recovery...
You can also clear the cache in fastboot mode using the command "fastboot erase cache". It will ask if you want to format/erase cache, say yes and it should clear your cache in a few seconds...

Thanks, I had tried various variations of that approach but the issue was a bit more complex than that. In the bootloader, the phone was detected by Windows and drivers from Asus installed properly. ADB wouldn't list the phone, but fastboot did. However, any operation by fastboot was denied access because USB debugging was not enabled prior to the phone going down. Otherwise, as you mentioned, fastboot erase cache would have worked fine.
In the end, I found another post on XDA by Theja which linked to a post in Spanish. The modified ADB and fastboot packet there contains a batch file that manages to bypass this issue and installs CWR, from which clearing the cache is possible. Upon reboot, Asus replaces CWR with the original recovery and things look back to normal.
Sweet, as long as you got it back up and running...

Hehe, thanks. I'm pretty happy indeed, was already considering the need for a new phone.
However, I must say that finding this toolset worries me a little bit. I thought the whole point of disabling USB debugging was to ensure that people can't perform low-level operations on the phone via fastboot/adb. In this case, this protection is somehow bypassed. I didn't have time to read through the entire batch file, nor am I proficient-enough in Android to make sense of it all, but I wonder how it was done...
In any case, I now have USB debugging left on. It increases convenience and the ability to recover things if problems occur, and it seems like the security benefits are not that strong anyways.
Hi,
I have a unique problem. I cant go into fastboot. Yes, fastboot on my OPT is not a opltion.
I cant instal TWRP. I can't wipe the OS to flash a new one.
My question is this:
Is there a way to wipe the partitions on a android phone via windows or something?
This problem is created by me. Somehow I flash OOS over CM (??)
So when my phone boots (bootloader is unlocked) I will see 2 boot sequences wich prevents me from accesing the fastboot menu.
The solution I see is this: Enter TWRP --> Wipe all but USB-OTG ...
Anyway, I hope there is a android Einstein here because I'm at a loss..
Feel free to ask any questions and pls help me!

If you are getting two boot screens, please confirm if this is what you see in your first boot screen:
some text which goes like "Your device cannot be trusted etc etc. fastboot oem lock something something"
If yes, press the volume buttons at this screen, which will take you to an "Options menu"
This will have options to power off, restart, recovery, fastboot, back to previous page.
use volume down buttons to move selection to fastboot and press power button to select fastboot.
This will take you to bootloader.
Alternatively:
Is the device getting identified by your computer when connected?
If yes, and if you have adb tools installed, try this command, after connecting to computer and selecting usb configuration as transfer files
adb devices
The result of this should show your device
then type:
adb reboot bootloader
This should take you to your bootloader screen.

Thank you for your replay.
I have done all of this and i do understand how this works.
I have adb drivers installed, my computer does reconizes my phone and everything works even the reboot to bootloader via CMD. (adb devices, it shows, etc)
When my phone then tries to access the bootloader, it will show those messeges " this devices cant be trusted etc etc." afther 5 seconds again I see the the android logo (with a few lines of static on the bottom) (( that clearly is not right )) but it will show me again the same message " this devices cant be trusted etc etc" ... then it will just show me the battery icon and power precentage (this if I choose to boot to bootloader) or else it starts normally..
Clearly the flashing of CM failed. And with a sideload to install OxygenOS I can use it.. But it does prevents me from accessing the fastboot mode..
So Is there an alternative way to install TWRP without using the fastboot mode? Or is there an other way i can try to wipe the partitions inc. the os?
From there I know what to do.

Hi
I was trying to add a custom rom and root my honor 7x.
So i installed a twrp-like recovery (with success), and with that, i sucessfully installed a new ROM.
But now my home folder (/storage/emulated/0) is not writable and seems to be encrypted :/
I cannot do a factory reset or install a new ROM:
- when i go to fastboot mode, i have:
- PHONE Unlocket
- FRP Lock
So i cannot flash anything with fastboot, and my recovery is no more accessible (don't know why...)
My question is, how can i unlock the FRP ?
Thank you very much,

Look in developer options, the "enable OEM unlock" switch is the "frp lock"
You might already know but I will say anyway just in case.
To boot recovery while phone is rebooting unplug USB and press volume up
To boot from adb use "adb reboot recovery"
From terminal app on phone "reboot recovery"
From powered off, make sure USB in unplugged hold volume up and power

Thank you for your reply.
Yes i know for the oem option in developper mode, but this option is grayed out (and enabled) but the frp is still locked :/
I also know about rebooting to recovery, but this is the default Honor recovery (nothing very usefull).
I tried the dload folder method (by putting an update.app into dload folder of my sdcard and then booting with + and - and power, but the update failes at 5%. It must be because of the frp lock).

I keep seeing this frp lock issue, comes uP after a reset in twrp or attempted exposed install, some other system change.
Are you on stock ROM and stock recovery?
If so can try to relock bootloader, that will make OEM toggle not greyed anymore. Then can make it off and back on.
Then unlock bootloader again
But only relock if on unchanged stock
I already tried to lock the bootloader again, with no success (probably bcs of the frp lock itself)
:/
Hi
I have same issue too.
How I can relock bootloader and then unlock it?
Hi all,
I installed TWRP on my Honor 7x, that went well.
Yesterday I decided to try to get Lineage working so:
- I installed EMUI 8, that went pretty smooth
- I installed Lineage OS 15.1. (without GApps)
- I flashed TWRP.
The issue I have now is that:
1) I can't install any APK in Lineage. Probably needs a factory reset/dalvik cache wipe.
2) I can't boot into TWRP. It stays stuck on the splash screen forever. This also means I can't install OpenGapps, SuperUser access (afaik), or anything else that requires root.
3) The bootloader is saying "FRP: Locked", which means I can't flash a new TWRP or a different ROM. When I try it fails with "command not allowed"
3) "fastboot oem unlock" fails saying I need to enable it in the developer options, but it's grayed out in the developer options because it's already unlocked.
4) I wanted to try the "dload" method but I can't find a good explanation on how to do it, and Huawei recently took all their downloads down, which means I can't find any UPDATE.app even if I knew how.
5) The other solution that *might* work is using "fastboot oem frp-unlock", but I need an unlock code for that (I assume the same one that you request for an OEM unlock from Huawei), and Huawei closed down the site that generated the codes.
So I'm stuck in a weird limbo where I can't move forward (install Gapps and use my phone as normal) nor backwards (go back to EMUI8).
Does anyone have any idea how I can fix this situation?

small chance you enable root from developer options. (i think it will be adb only)
if so , maybe can use adb shell and "dd" to write recovery to correct partition.
problem is many of the available twrp do not boot on custom rom .
example code. (if you do wrong , it may be bad)
Code:
dd if=/ext_sdcard/twrp_Recovery_ramdisk.img of=/dev/block/mmcblk0p32
It seems like I'm allowed to use dd in ADB shell, but before I run it, what do you mean by " problem is many of the available twrp do not boot on custom rom . "? I thought recovery was independent of the ROM? And does it mean flashing twrp like that could brick my phone?

Like what you have , twrp stuck on splash screen
I managed to unlock the FRP with DC-unlocker. Sucks that it costs money but it worked!
Now Im stuck in a TWRP boot loop though.

At this point you should have access to fastboot though, right? I'd try a different TWRP instead. Perhaps try this one: https://drive.google.com/file/d/1ZYo7Ndte3vlLcUSadD6jIgfBi1oxa0Pb/view?usp=drivesdk
Just to clarify, it gets stuck on TWRP splash screen. When I turn off the phone, it immediately boots up again into TWRP. I tried getting into fastboot mode with all kinds of combinations of button presses, but no luck. Not even Volume Up + USB cable works

This is because after the frp unlock, it needed to see a factory reset, and it usually needs to be done with stock recvery.
So will have to wait till battery is dead and and plug in usb while holding volume button. Should then load to fastboot. Where it is best to flash stock recovery to clear the recovery bootloop. The bootloop is do to the fact yo unlocked frp and now phone needs to wipe/data

Sorry, only saw your answer after sending my other reply. In theory I should have access to fastboot mode. However, everytime I start up I get into TWRP, which doesn't work. I tried Volume up, volume down, both, with and without power button, with and without cable, and no dice.

i just took mine apart and discconected the battery and still no luck that program deleted my fastboot
Please can you tell me the process to install twrp I have the L24
I waited all the way till the battery drained, stuck in the USB, and it booted to ROM! Sadly it immediately shut off again because the battery is dead (even with keeping the USB in). I'm going to keep trying though.
I can't get into fastboot mode. I can get into the ROM by letting the battery drain completely on the TWRP splashscreen, and then sticking in the USB cable. However, no button combination or "adb reboot bootloader" or rebooting to bootloader from the ROM brings me to the bootloader. I wonder if it's still there. Any ideas?

Seems to be a f-up situation either way.
You have adb DD available, found out before.
Don't know if maybe flashing stock recovery is good idea at this point.
I think fastboot.img can be flashed with DD too, but don't try till someone can confirm.
If flash stock recovery clears the loops, maybe best to do full-ota manual flashing.
I managed to get an UPDATE.APP file and extract fastboot.img from it, as well as all the other .img files. If someone can tell me what to flash and how (with dd), I think Im set.

Fastboot.img is the large part the bootloader. If flashing it goes bad, might be dead phone after, just rember that.
Will add a list of partition names and command s for you soon.
here is a list of oreo partitions and there /dev/blk/** number
and here is an example of code to save images with dd assuming you put the images on your extrnal-sdcard in folder called oreo-images
Code:
dd if=/dev/block/mmcblk0p5 of=/mnt/ext_sdcard/oreo-images/fastboot.img
Do that save first and compare the md5 of the file from update.app to this file.
or just check the md5 before making the copy
Code:
adb shell md5sum /dev/block/mmcblk0p5
If you are conviced you need to flash the images, here is example of writing the image assuming files are in sdcard folder oreo-update-images
Code:
dd if=/mnt/ext_sdcard/oreoupdate-images/fastboot.img of=/dev/block/mmcblk0p5
As I have said, this might be bad advise , I have not done fastboot.img flashing before. But on other devices it is same as lk.img or uboot.img, There is danger in flashing it incorrectly. That is why my suggestion was to flash no-check-recovery and do manael update with "echo -update_package" commands.
Along with the statement that fastboot.img is similar to lk.img or uboot.img on other phones, Your fastboot cannot be gone. because phone boots.
but do let us know how it goes.
I agree it would be better to flash recovery if possible. I assume I need the NoCheck-Recovery image from this thread? https://forum.xda-developers.com/honor-7x/how-to/manual-update-to-oreo-beta-emui-8-bnd-t3767044
And what partition do I have to flash it to? I'm guessing either /dev/block/mmcblk0p28 (erecovery ramdisk) or /dev/block/mmcblk0p32 (recovery ramdisk)? I'm not sure what the difference is between erecovery and normal recovery.
(didn't flash fastboot yet, wanted to see if recovery was doable).

To recovery_ramdisk. 32
What about check md5 of fastboot partition, that will be helpful to know if it did get wiped out.?
Hmm seems like I'm not allowed to use dd after all:
HWBND-H:/ $ dd if=/storage/7C96-7E17/BND-RECOVERY-NoCheck.img of=/dev/block/mmcblk0p32
dd: /dev/block/mmcblk0p32: Permission denied
And here I was thinking I was close to solving it...
Also can't run md5sum on the fastboot partition, since that needs root as well.
