Bad boot animation bricked nexus 7 2012 edition - Nexus 7 Q&A, Help & Troubleshooting

I made my own custom boot animation. I used an existing boot animation structure. Difference was mine used *.png files instead of *.jpg files. Which I thought all boot animations were supposed to be png. The other difference is the fps, I changed fps from 24 to 4
I renamed /system/media/bootanimation.zip to /system/media/bootanimation.bak
Copied my custom boot animation to /system/media/
Rebooted..
Google appears with the small unlocked icon for a few seconds, then disappears to blank screen, which I'm assuming is my boot animation. It never shows, never boots, just sits on blank screen.
Tried turning it off, it auto reboots, never powers off. If I hold all three buttons it will reboot and pull up the boot loader. I try going into recovery, google appears with unlocked icon, and never goes black never loads recovery.
This nexus 7 is running paranoid Android 4 beta1 or 3.99 rc2 can't remember..
Twrp 2.2.2.0 for recovery..
As of now I'm letting it show the black screen waiting for battery to die in hopes that I can charge it, without it powering on, then hold all three buttons, load boot loader, then load recovery and it work.. But I don't think this will help..
I've tried a bit of googling for nexus 7 bad boot animation, and found nothing useful.. Hope someone can help, thanks!

Update....
The nexus 7 is not bricked.. When it loads black screen it is loading my boot animation, and obviously fails, the tablet dies finish booting, even though I didn't think it was.. If I turn tablet horizontal I can see the right 2-3 inches appear, apps, lock screen, etc.. But rest of screen is still black, but if I touch other part of screen while in app drawer, it does open that app.
So in vertical mode I have a black screen overlay.. In horizontal I have only about a 75 percent black overlay that is left justified.
I'm hoping I have adb enabled so I can go in and delete the custom boot animation I made and all will be well.. Or at least see if I can navigate only seeing the right part of screen so I can enable adb or even delete the boot animation itself..

Never heard of this issue, even if you put in an incompatible bootanimation and forget to change permissions to it (which I don't believe you did) your tablet should still boot fine and perform just fine just get a blank screen during boot up
Is it possible you did something else? As this issue seems yo be more than just a bootanimation
If I were you right now I would attempt to flash or at least boot a new recovery through fastboot
fastboot erase recovery
fastboot flash recovery nameofrecovery.img
Or just
fastboot boot nameofrecovery.img
In this recovery adb should work fine
adb pull /system/media/bootanimation.bak /location/on/pc
Now change it back to bootanimation.zip
adb push /location/on/pc/bootanimation.zip /system/media/bootanimation.zip
Now either fix permissions in recovery or chmod with adb, also may need to mount system first
And for future reference always make a backup first

I did nothing else, the tablet actually boots, but all black screen in vertical mode.. In horizontal mode you can see maybe 25% of the screen, the rest is black, but still functions..
If I adb in from Linux, move original boot animation back, reboot, works fine.. I think it's something to do with my zip file or something, I've even took original stock boot animation and edited its images, created a zip, installed, reboot, same thing..
Adb in, move original, reboot, good to go again..
Today I'm going to try unzipping, and just rezip, install without changing any files and see what happens..

If you want upload me a copy of original along with a copy of the new one you made and I'll have a go at it

That boot logo, or boot screen is in a restricted partition. Even with root access it's hard to change. it basically takes pushing a copy of the partition without the image on to the phone then writing a script to push a new image in the hole created. It all has to be done through adb

you dont need the App you can change it bye downloading the zip file for the new boot animation putting it on your SD card then using rootexplorer to back up the stock animation in /data/local/bootanimation.zip after you back up the stock animation just place the new one in the same folder /data/local/ and rename the file to bootanimation.zip then restart. Here is a few animations to start with

[Q] How to change the Boot Splash?

I am currently running the CM7 nightlies off the eMMC on my Nook Color.
When the device is powered on or rebooted, when loading from the eMMC it displays three things before getting to the boot animation:
1) "Touch the Future of Reading" in portrait.
2) A quick, corrupted-looking "Loading" in portrait.
3) The word "ANDROID" with a blinking cursor behind it in landscape.
After those three items display, then it shows the boot animation (in portrait).
If I boot from SD card, none of those three boot splashes show. So I'm guessing the three boot splashes are stored internally. Maybe even in the magic /boot partition we aren't supposed to touch.
Can we change the boot splashes? If anything, I'd rather have a blank/black screen displayed instead of the three ugly splashes there are now.
Having one screen would be nice also. Something maybe that just has an Android log in portrait before the CyanogenMod animation starts.
I'm booting CM7 off uSD and I'm seeing those 3 screens. I installed multiboot so now I don't see "the future....." but a boot menu, but I still see the other two.
So, at least from reading about the Gtab, I assume NC has a somewhat similar way of doing things...
The first screen is its own partition, so you would need to figure out where that is, find the image on it, then replace it.
The second is (I think?) the command to load either recovery or boot to the rom.
The third is the kernel starting up (again, I think?). Dal probably put that there so people know what is going on, but I bet it could be removed and replaced by nothing pretty easy.
It looks like with CyanogenMod 7.1, it goes from the "Touch the Future of Reading" screen straight to the boot animation.
I tested a 4/30 build of 7.1.0 and it just flashed the screen instead of showing the "Loading" and "ANDROID." text.
So, we're almost there.
Where's 7.1?

I'm not interested in changing the boot animation. I want to change the static boot splash on power on.
It use to say "Touch the Future of Reading", and with the Nook 1.2 software, it says "Read Forever" or something.
The static splash may be in /boot
I'd love to get rid of those three as well...
On a sidenote, does anyone else have a REALLY long delay on the "Touch the future" screen whenever they boot up the first time after charging? Mine sits there for at least 2-3 minutes before moving on to the Loading and Android_ screens.

Nexus 7 unresponsive in bootloader

I've been searching while at work trying to find someone with a similiar issue and have not met any luck.
I've tried the 2 different 1 touch root programs to no avail. I am able to unlock my device fine, but once it tries to push the img for CWM the Nexus 7 becomes unresponsive. It will lock up. The only way to get out is to hold the power button until it powers off.
After a few attempts with both 1 click tools I gave up and just decided to use ADB and do it myself.
What I can do:
lock/unlock the device.
reboot to and from the boot loader.
install apk's while in the Android OS
What I cannot do:
Push any file to the Nexus 7 while in the boot loader.
Once I try to push the img for CWM the device locks up, becomes unresponsive, and the fastboot devices command does not show any devices connected anymore.
Currently using Windows 7 Ultimate x64 and OTA 4.1.1. I've tried numerous known working USB cords and the OEM cord. I've used both sets of drivers included in the 1 click root tools, the "naked" drivers, and the set of drivers that work for numerous devices.
I'm a complete newb with ADB and don't know much about it. is it possible to copy the CWM img to my internal storage and install it from the internal storage rather than pushing it over USB?
I'm currently at work, and do not have admin on this PC or I would try again and see if I have the same problem on a different system. Tonight when I get home I will try my girlfriends PC, and I do have a dual boot of linux I can try from as well. But if her PC and linux both fail I'm probably going to have to return it claiming I have display issues and get a new one.

Using root tool kit make sure you have stock ROM selected before you select root. Once you have stock ROM selected you should be able to root.

When using either root tool, as soon as the tool starts pushing the custom recovery over the Nexus becomes completely unresponsive. The device itself locks up. At this point it does not show up as a connected ADB device anymore on my PC. I need to hard power it off and reboot for my PC to see it again.
Both tools boot it into the bootloader fine, and both tools can unlock the bootloader fine. I can do it with ADB manually as well. But as soon as any of them start actually pushing the CWM img file over that's when the Nexus locks up. Volume up/down do nothing, power does nothing, my pc doesnt recognize the device anymore either. All I can do is hard power it off by holding the power button.
At this point I'm convinced it's either some strange issue on my PC, or the nexus itself. I'll know for sure once I try it again on my girlfriends computer tonight.

If what your describing is when you go to push custom recovery screen locks up should be black screen with Google on it then your computer says can't find device something like that. Mine did the same thing, in the tool kit upper left corner it ask for model type, make sure you have correct Android selected. I selected custom rom by mistake and it just hung there on the black screen. It should list custom ROM, Android 4.1, or Android 4.1.1 Select what you have and it should work....hopefully.

Unfortunately not. I have selected the right options. It freezes on the bootloader screen. It never even makes it to the boot stage. I've tried to flash a recovery permanently and temporarily boot from a recovery as well. It freezes either way.
Additionally if I boot to the boot loader, and select recovery it will not boot into the stock recovery at all... It just sits at the google splash screen with the unlocked padlock.

Same thing here. I flashed a new CM. Did a full wipe including cache then flashed a new GAPPS, and now I'm stuck at the Google screen. I can get into fast boot, recovery etc but cannot get my phone to boot. Any ideas?
1. wipe factory
2. wipe dalvik
3. wipe cache
4. flash cm then gapps then kernel
Thanks zephiK. Problem is I don't have a ROM on my sdcard mount. How can I copy a ROM to my phone without getting into android? Thanks for any help!
If you can get into recovery (CWM) then you can use ADB to push the file. Look through some of the PINNED threads for the commands. Very helpful info.
I found that my data partition was not able to MOUNT once and nothing I could do via ADB shell would change to it to R/W so I just locked and unlocked my bootloader and all was well again.
you can either use fastboot to push the files to your phone or flash stock. if you dont know how to use fastboot try wugs toolkit

[PROBLEM] MI A1 Black Screen Image after boot Image

Hello, it is my first time trying to write a post on xda so excuse me if I do something wrong.
I've been playing with Roms a lot of time, installing, uninstalling, bricking and unbricking phones. so have a pretty good idea of how it works but now I just don't know what I did wrong and my phone is just ... in a black screen after boot image.
I was currently on DP5 android 9 by @joeyhuab and everything worked perfectly. Today was released android Pie and I just want to try it. So, I made the steps for DP5 to PR1 and everything runs well until I reboot from TWRP to the system. Now when I turn the phone on. it just appears the boot logo and later a black screen.
I can't restart the phone pressing the power button after some seconds but it goes to the boot image and later the black image screen (of the dead) appears.
1. I can't go to TWRP. (power+ Vol+)
2. I can't go to Fastboot. (power+ Vol-)
3. Charge Image is not displaying.
Windows sounds when i connected on the black screen state but fastboot don't.
This is my first time dealing with this kind of problem. I just don't know what would be the next step to try, Mi A1 is one of the best phones and I don't want to lose it.
Thank you for reading XDA, You are the best

I also had this issue I think it is because of any xposed modules or magisk modules.

I am not able to do that I can't go to twrp mode here also same black black screen.I can go to fastboot mode but I am not enabled usb debugging mode and system is not recognising mobile.
Help me how can I solve this..
Thanks in advance. ?
Install 'scrcpy' in your PC. Try to flash twrp from PC using fastboot and adb method. (I hope fastboot shows up on your phone) if u can boot to twrp via PC then go ahead and install any other rom. If u can't then connect your phone to PC and open scrcpy.exe here you can control your screen. (Most custom roms come with usb debugging enabled, if not try " AEX V.6.1 rom)
Usb debugging is compulsory. Thanks a lot for the information I will try this.
So i had this exact same issue. It was booting to twrp but screen was just blank.
i was trying to root the devive so i flashed the zip file by following command through adb
adb shell twrp install /sdcard/Magisk-v23.0.zip
it flashed the magisk and it was done. Similarly you can flash any zip file. If zip file is not copied to internal memory you can copy it using following command
adb push Magisk-v23.0.zip /sdcard/
I hope it helps someone in need.
Thanks.
Hi similar problem. Phone was locked in bootloop. I use reset pin and flash latest fw, flash successful in 220sec. Then screen stays black. Holding any combination will power up phone with black screen... wonder if it burn resistor or it is a flash issue. Trying to reflash again, however it stays 1000sec and still flashing.
Hi have mine FIXED.
Tried again to flash with android 9. Not able to finish flash in 4hrs. Then disconnect. Screen show battery 100%, then again only black screen but powered. Also 3 buttons are lighting. So I start pushing them and the screen, got some feedback and sound from touching the screen. Then the phone restart, screen ON. Show the normal white screen and ENCRYPTING storage screen that should come after flash. Then again reboot itself and start installing android (just taking a lot of time). Now all work on android 9, not giving option for OEM update to android 10, however afraid to flash again... good enough for my son (either way will break it in an year).
p.s
Im Samsung S class user for 10 years, so it is quite unfriendly phone... (need debugging on to connect to PC, for file transfer )
