[Q] Nexus 7 gets stuck booting. Tried reflashing stock OS multiple times.

I seem to have got myself into a bit of a pickle here.
I had a rooted N7 on 4.2.2. Tried to unroot (in lieu of going up to 4.3). Disaster struck! It wouldn't boot. It would just get stuck at the bootloader and go "Booting failed" or something similar.
So bother, I could get into the bootloader. So I tried to fastboot flash a stock image using this (http://forum.xda-developers.com/showthread.php?t=1907796) guide.
I got a bit further now, it would get the X loading screen but then no amount of waiting would have it boot.
So I tried factory reset from the recovery menu (the one with the Android and the red triangle).
No good, still did the same thing.
So I tried using Nexus Root Toolkit to flash stock + unroot from a soft-bricked/bootloop state. Nope! No good. Still does the same thing.
I've been through every combination of flashing, clearing, resetting but to no avail!
I've tried flashing CWM and TWRP but when I try to get into recovery mode, I just get the Google logo forever. This is a nightmare!
What's going on Have I managed to brick this thing...

Hey,
did you try doing all these manually :
Code:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader.img
fastboot reboot-bootloader
fastboot -w update image.zip
PS : Edit these according to images you are trying to flash.
You mentioned you tried the guide but try this once again.
Unlock your bootloader / keep your bootloader unlocked while doing this.
If you want to you can even try running the .bat files and / or .sh files while in the bootloader.
If it still doesnt work , download the latest custom recovery and just try flashing it through
Code:
fastboot flash recovery recovery.img
Please mention the errors you have a bit more in detail during these steps !

Okay, I've managed to get TWRP up and running.
Now... how do I get a ROM onto there to try to flash? >_<
PS. I did all those commands manually many many times. It's got to a stage now where the X logo never actually comes up... Just the Google logo and the little padlock

Amazing. I actually managed to flash a copy of Cyanogen on there and it all booted perfectly.
Now I wonder if I can get it back to stock from here easily..
Thanks

You can ... just make sure you have downloaded the right factory images and flash the use the .bat / .sh to flash the images .. keep in mind that you will lose all your data including that on the internal sd. All the best

So close...
Downloaded the new SDKs from Google and managed to actually flash and get into a stock version of Android... but it's constantly saying "Google keyboard has stopped working! Launcher has stopped working! etc" and it's practically useless
Gaaaaaaaaah

Okay my solution to this:
Just keep flashing it with the flash-all.bat command until it just... worked.
Must've done it about 15 times.
Well that's that ordeal over.

Warning - XT1060 Blur_Version.212.55.26 blocks custom recoveries

Exactly as the title says ... after flashing this update, even if unlocked, you can no longer flash a custom recovery.
Fastboot will show a successful flash, e.g. :
mfastboot.exe flash recovery twrp-2.8.6.0-ghost.img

writing 'recovery'...
OKAY [ 0.969s]

But when you try to boot recovery, it's stock recovery.
This makes any attempt to flash a rom, regain root, etc. impossible.

And you are booting straight to recovery after flashing via volume down and then volume up to select not the power button?

After you flash TWRP, at the command prompt type:
fastboot reboot-bootloader
I can't remember where I read it but some people said they had to do that to get the custom recovery to stick.
THEN unplug your device from your computer and reboot into recovery by scrolling down with the volume down button to highlight recovery and then hitting the volume up button to select recovery.

Ok, figured this out ...
(was able to back down to the original 4.4.4 w/rsd-lite and regain TWRP ... to develop this process)
So ... the following can be done to upgrade to this new version, and retain TWRP (plus you have the new recovery later on for 5.1 when it comes along ...)
First, the presumption here is you are unlocked. If you are not, none of this will work.
Also, you will need RSD-Lite installed and operational.
Download :
https://dl.dropboxusercontent.com/u...RIZON_4.4.4_KXA21.12-L1.26-3_cid2_1FF.xml.zip
https://dl.dropboxusercontent.com/u...4.4.4_KXA21.12-L1.26-3/twrp-2.8.6.0-ghost.img
https://dl.dropboxusercontent.com/u/22067374/GHOST_VERIZON_4.4.4_KXA21.12-L1.26-3/servicefile.xml
Unpack the GHOST zip file, and overwrite the "servicefile.xml" in the unpacked folder w/the one you downloaded, then copy the twrp .img in there.
Fire up RSD-Lite, put your phone in fastboot, and apply this update by loading the servicefile.xml as the update.
It will update everything, installing the TWRP instead of the new stock recovery.
Note: you can delete the twrp line in servicefile.xml if you wish to retain your existing custom recovery.
When done, you should reboot, update, and be up and running with the new 4.4.4 and TWRP ... so easy path back to root via TWRP.

I think all that needs to happen is after you flash TWRP - you don't boot into recovery. Instead, reboot into bootloader mode. This has been a problem from the beginning for some people with their MX13's and not a new thing. I don't think it has anything to do with the update. Some people have to reboot into bootloader after flashing TWRP in order to get it to stick for some reason.

@_litz Please understand that @JulesJam is correct... the proper way to flash a recovery is as follows...
Start the phone to the Fastboot AP/Bootoader menu
using moto's fastboot (aka mfastboot) exectue the following...
mfastboot flash recovery RecoveryYouWishToFlash.img
mfastboot reboot-bootloader
Then use the volume/power keys to enter recovery.
Once in the recovery, it is safe to Reboot the phone normally.
that mfastboot reboot-bootloader step has been crucial for getting the newly flashed recovery (3rd party OR Stock!) to "stick" on the phone.
Flashing with RSDLite is over kill.

You'd think that would be the case, right?
Except those EXACT STEPS ... didn't work.
If you attempted to boot into recovery directly from the bootloader, it rebooted the phone, which booted the OS.

And you used volume up to enter recovery after flashing twrp? That is the most common problem I see.

That is because you are pressing the power button when you should be pressing the volume up button.

Yep ... ain't my first rodeo ....
It flat out refused to take recovery.
I had to back it back down to the old 4.4.4 version, reflash TWRP, then I simply applied the whole RSD package (sans recovery) to re-upgrade it to the new 4.4.4.
Worked like a charm.
(Plus it gave me a chance to extract the fxz from the moto manager app)

You needed to reboot into bootloader by typing fastboot reboot-bootloader after your flashed TWRP. THEN disconnect your phone from your computer and boot into recovery by using the volume down to highlight recovery and volume up to select recovery.
If you follow those instructions, you will flash TWRP fine. No need to go through that long drawn out process you came up with.

Probably should rename or delete this thread, since its fairly misleading.

Check in the /system partition for a file named recovery-from-boot.p or something similar. If that file is there it will reflash the stock recovery when you reboot, and I've seen it reflash when booting into recovery.

I just used the TWRP manager app from the Play store after reverting to stock recovery and installing the OTA. It worked perfectly the first time.

I'm curious as to what is different.. because the other day after flashing stock recovery back on my phone, taking the update to 212.166.3 KXA21.12-L1.26-3 which Verizon just pushed, I used those EXACT STEPS to put TWRP back on my phone and had no problems.

Beats me ... for me, it didn't work ...
So after I got things back onto the old 4.4.4 version, I put together the FXZ with the modified xml file, and simply re-updated, applying both the update, and TWRP, all in one go.
anyone else on old 4.4.4 can do the same thing if they wish, which was why I posted the links and the instructions.

not to bump this thread, but I had zero issues going from stock with 212.55.26 ota update installed and flashing twrp. it just worked like normal.
i would agree with @superkeest seems like this thread should get renamed.

This requires you to have an unlocked bootloader which will wipe data if you have not unlocked already.
Recovery does take some time to boot It has taken up to 45 seconds for the TWRP curtain to show for me
To get to bootloader without adb:
Turn device off
Hold Vol Down
Insert USB plug while plugged into your PC
Hold Vol Down until fastboot pops up
Instructions:
If you have issues with adb or fastboot follow this post: HERE
If bootloader is unlocked:
reboot into bootloader
Code:
adb reboot bootloader
fastboot flash recovery twrp-2.8.7.1-h901.img
fastboot boot twrp-2.8.7.1-h901.img
If your bootloader is locked:
enabled developer options
in developer options "Enable OEM unlock"
reboot into bootloader
Code:
adb reboot bootloader
fastboot oem unlock
fastboot reboot-bootloader
fastboot flash recovery twrp-2.8.7.1-h901.img
fastboot boot twrp-2.8.7.1-h901.img
Known issues:
You get to see that it's not truly 2 displays
Time is not saved from Android to Recovery
Display does not turn off when it times out
TheJesus said:
I've messaged @KAsp3rd to include it in his OP.
ONLY PERFORM IF YOU HAVE ALREADY FLASHED TWRP AND CREATED AN EXTERNAL BACKUP!!!
1. Hold Volume Down
2. Hold Power button until you see LG screen
3. Release Power button and then rehold Power button
4. Follow on-screen prompts to perform a Factory Reset (If you have TWRP, this should not actually factory reset, but there has been one case of it doing it, that's why I suggest keeping a copy of your backup on your computer), may take a minute to boot into TWRP
5. Enjoy TWRP without fastboot
EDIT: On hold until verified on latest TWRP/more devices.

-Welcome to Fastboot Mode:

{fastboot reboot}
-Phone back in Android
{adb reboot recovery}
NO TWRP
Right now I'm using stock.img files to restore everything and retrying.
I'm currently using Minimal ADB and Fastboot [8-28-15] to push commands.

I can't push stock.img from fastboot. Reading from mickeyinid post in that thread, "Make sure you have the newest fastboot binary or it won't flash the system.img" It has a cap at 53MB but the filesize for system.img is 4.2GB.

android has a file /system/etc/install-recovery.sh when you boot up it overwrites teh recovery with stock, chances are its doing that.
boot into fastboot, flash it, then use
fastboot boot twrp-2.8.7.0-h901.img
that will drop you into recovery (it takes like 30 seconds) form there you can do a syou wish, then click on reboot system and it will remove that file so youll have twrp always.

Once I put in the fastboot boot twrp-2.8.7.0-h901.img command, I heard the computer disconnect and it took more like a minute or a minute in a half but it worked. Then I flashed SuperSU and now I'm ROOTED!!! Thanks!!!!

All rooted. Thank you @KAsp3rd!!

Yes. I have it. Use the arm64 for Lollipop version. It does however break the second screen occasionally (it FC's when I get/make a phone call, but that's it). BUT it has RootCloak which lets me use Android Pay while rooted

Success! The whole process was very easy and worked the first time! Thanks for posting this!

Unable to root using Nexus Root Toolkit 2.1.0 and Nexus Player Marshmallow MRA58N

I am having a difficult time rooting my Nexus Player on Marshmallow 6.0 MRA58N
I select the "Root" option and it pushes 3 files to my Nexus Player. Then it boots into TWRP and I plug in my mouse so I can flash:
-beta-supersu-v2.52.zip and
-busybox-signed
Then I reboot system but that's when I get the stuck logo.
I flash the provided files in recovery and then I reboot. However, when I reboot, I just see the animated logo (the one with the balls bouncing from left to right). It is stuck there. What am I doing wrong?

Same problem here, someone help plez.

I haven't even been able to get ADB or Fastboot to detect my NP.

forgot something
looks like i skipped this part . Once you're in TWRP, install the stock boot image and then the Magisk/SuperSU zip.Is there anything i can do?

adb only works while phone is booted into system so nothing wrong there. If you're in the bootloader menu where you see that the status of your device is unlocked then you're already in fastboot mode. Just flash twrp again and the sideload stock 8.1 beta boot image (you can probably find it on xda), sideload magisk too. Go into install and press flash image file and find the stock boot image and then go into install again and change to flash .zip and flash magisk. After that, reboot into system.

WOW thank you so much'

No problem. Thank you very much for the donation, that was really kind of you. Hey I'm sure you'll get the hang of it before android P drops. you did figure out what went wrong all by yourself so get a hold of the right boot.img and the rest is exactly as how you did it in the first place but flash the boot.img before magisk. Let me know if you want to give it a dive again.

I'm on 8.1 boot loader unlocked and ready to try to root again .Thanks for the help

This is the closest thread i could find to what is happening to my PH-1.
Like videodave1 I 'was' running the latest stock 8.1 and have my bootloader unlocked. In trying to root the phone I did this:
flash boot flash boot twrp.img
adb shell twrp sideload
adb sideload magisk.zip
All installations went well, but when trying to reboot from twrp it forced me to install the app. After that the phone went into boot loop.
* Note how I didn't sideloaded the Oreo 8.1 image before magisk.
By pressing all 3 buttons I can get the phone to reboot and releasing the volume up I can get to Fastboot. Just volume down and power doesn't work.
The problem now is that adb and fastboot no longer recognise the phone. adb devices just gives an empty list and fastboot only shows < waiting for device >
Trying to go into Recovery mode doesn't work either. Power off doesn't work and Restart bootloader, well, restarts the bootloader.
It might be relevant to mention that I'm running adb and fastboot from Terminal in a Mac and that this is my very first and frustrated attempt to root any phone.
For reference this is what the FastBoot Mode brings:
PRODUCT_NAME - Mata
VARIANT - OPENUS
BOOTLOADER VERSION - mata-aad8ac4
BASEBAND VERSION - 2.0.C4-M1.3.1
SECURE BOOT - yes
DEVICE STATE - unlocked
I might have to just resign myself to the ordinary land of unlocked full stock phones
Thanks very much

Just flash twrp again and the sideload stock 8.1 beta boot image (you can probably find it on xda), sideload magisk too.

I might be missing something hopefully obvious here. How can I flash twrp again if I my computer can't see the phone. With the USB phone plugged in and in the FastBoot screen I enter into Terminal:
fastboot flash boot twrp.img
and I get:
< waiting for any device >
How do I flash it from the FastBoot screen? BTW, going to Recovery mode just hangs at the Essential logo.
Thanks

Thanks Arju. If you are referring to the FastBoot menu where you can use the up and down volume keys to select Start, Restart Bootloader, Recovery mode and Power off Yes, but not much else unfortunately.
If I select Recovery mode I don't go to the screen with the blue buttons from twrp.
Thanks

What you need to understand is that twrp will not stick after you flash it. This device does not have a recovery partition and that's why you replace the boot partition with twrp and while you're in twrp you need to flash the boot.img back and whatever mods on top of that such as kernel etc.. If you flash a rom then it will replace the twrp with the boot.img found in the rom zip.
So now we need the computer to recognize you device. Could you unplug the cable and change the usb port on you computer. connect your phone while you're in the bootloader menu where it says start on the top.
The use use fastboot command: fastboot devices
See if the computer recognizes you device.
