Nexus 7 2013 not going past boot animation

My Nexus 7 2013 running stock 4.4.4 is not able to boot up to the lock/home screen. It just stays at the four dots or petals boot animation indefinitely. It does not freeze(animation goes on smoothly) nor does it go back to the bootloader again.
I have done cache wipe and factory reset.
I have flashed stock 4.4.4 factory image again and in the process unlocked the bootloader as of now.
But there is no change in the situation. I love this tablet and I am desperate to get this sorted out. Please help me.

I am in the same situation. I got my device back from Asus repair today, it was unlocked and running a custom KitKat rom, but only the screen was broken and that was what was repaired (at my own expense).
I turned it on and it was stuck at the 4 swirling dots for more than 20 mins, so I wiped the device completely in TWRP and tried to flash a stock factory image (Lollipop) - same problem. I tried flashing a factory KitKat image, also stuck at boot animation.
I then re-flashed TWRP since it had been replaced by the stock recovery, and then sideloaded a custom Lollipop rom (Screwd) - still same problem.
It is strange that I can use adb and fastboot, but nothing gets past the swirling dots. Hopefully someone can point us both in the right direction....

If the tab gets to the spinning dots, it means the bootloader is not corrupt, so there must be a way to restore. Since there's nothing else you can do, why don't you back up the tab, then erase everything, especially formatting the internal storage (using the format button in TWRP) twice, and re-flash a rom. It seems some residue is preventing the thing from booting up. It happened to me on the TF300 a few times when the new bootloader was incompatible with the old one. Good luck.

Depending on the TWRP version, some claim it would fail to format completely. Phil's Touch (Arter's version 6.58.9) however would. You might want to try that. I personally haven't experienced it with this model, so I just pass the information along. Unless the EMMC physical structure is damaged somehow and cannot be written to, in which case the only solution is a replacement motherboard since you cannot find an OEM Emmc, let alone replace and program it.

So you sent your tablet to ASUS to have the screen replaced and they sent it back to you unable to boot? That's not something you should have to deal with, I'd call ASUS and demand that they repair it.

That's what I've done now, but I was hoping to avoid sending it off for 2-3 weeks after already not having it for the last 2 1/2 weeks

Yeah, that sucks. I'd probably try and fix it myself too. But with what ASUS charges for repair you'd think they'd send it back to you on perfect working order. I called yesterday to see what it cost to replace the screen because mine is all scratched up and they wanted $200. Ridiculous. Might as well just buy a new one.

Any other methods to fix this problem anyone?

Did you update the bootloader to 04.14 ? It is required to update the bootloader to run lolipop. Try flashing the new bootloader.IMG and then installing stock or custom lolipop ROM.

All I can suggest right now is try a different ROM like aosp or cm official. You seem to be doing everything correctly. You can also try flashing the original 4.3 factory image with 03.14 bootloader maybe it'll boot. Then revert back to lolipop.

[Q] Loads of Problems (rooted, unrooted, firemwares, flash, stuck on logo screen)

I'm having one hell of a time with this tablet. This is pushing a month and I'm still not satisfied with my tablet.
Tonight I finally tracked down what I had hoped was a stock firmware for my tablet. Halfway through the download it timed out and when I went to download it again, the same thing happened.
So I tried to take my tablet that isn't "properly rooted" anymore and use Odin 9, instead of Odin 10, and place kitkat on my device rather than be stuck with Lollipop 5.0.2. All of this because The Sims Freeplay app isn't working and I can't find another soul on the face of the earth who can give me an answer to why this is happening.
Now I'm stuck on the samsung logo. I managed to get it back in download mode and that's where I flashed Lollipop 5.0.2 through Odin 10. I figured that would solve my problem. It didn't, but at least I got TWRP back on my device.
I never recovered anything that came with my tablet. I did not think I'd ever go back to unroot nor did I know how to back it up in the first place. So there's nothing in my recovery I can boot from. So what I did was I came back here and I downloaded the recovery for TWRP. I flashed it from my SD card, it told me it was successful... now what? I've rebooted and my device still loads to the samsung logo...and just stays there. The little confetti animation happens behind the logo, but that's it. It doesn't turn off. It doesn't reset itself.
CAN SOMEONE PLEASE TELL ME WHAT I'M DOING WRONG?!
I've already voided the warranty on this device and I regret almost daily that I decided to root in the first place. I say this only because I think rooted devices are top-notch, but I haven't been having very much luck with them. It took me a week to root. When I finally rooted then my favorite app game stopped working. Then I figured I could flash the stock firmware easily (but it seems like every place I go to find kitkat or even stock lollipop I can't find or I do, but files are corrupt or sites are full of ads).
I can't use my device at all now except click around in TWRP which isn't doing me any good.
I just want my tablet back. I spent 500 dollars on this thing and I haven't had time to even enjoy it. It's only two months old.
Please. Again. Someone HELP me. I want to figure this out and I don't want to accept that I bricked my device because I've watched plenty of videos on youtube and people are stuck with a phone that's resetting and all they do is fix it right there in front of my eyes.
Why can't I fix this? What is it that I'm not doing properly?

I just skimmed through all this reading, so I may have missed a few things. The thing I didn't see if factory resetting. You need to factory reset in twrp. Just go to wipe and factory reset. Now reboot and wait at least 20 minutes as it does take quite a while to boot.
If doesnt do, transfer a custom stock based ROM for your device (any KK ROM should do) to your SD card. Factory reset in twrp and flash ROM. Now reboot and wait.
Typically, flashing with Odin takes 20 minutes to boot up for the first time. Just be sure you factory reset.

Custom Stock Based Rom? Does that mean I'll push myself further away from a stock firmware? Also... where do I find one and are there instructions for it? I thought roms were firmwares up until like 4 hours ago and I've been reading of roots for a little over a month now.
I see you've got the same tablet. By any chance are you running 5.0.2 lollipop and do you happen to know having a rooted device is the reason why The Sims Freeplay won't get past it's splash screen or if it's the app itself and it's newest update that made it wiggy?
I'll flash whatever at this point, but my main reasons for continuing to mess with my tablet was because of not being able to play the sims on there. Every other game I play works.

The Sims may not work because its uncomptiple with lollipop.
Simply, hit wipe in twrp, hit advanced wipe, and tick system, dalivk and cache. Then go back and install the Cm11 zip and reboot. Hopefully it gets you booting

I'd actually flash this as its more like stock just debloated.

You need to wipe system, dalvik, cache and data then Install via twrp.
Wait at least 10 to 15 mins after install for initial boot up.
For future reference whenever you go back to kitkat from lollipop you need to wipe the data and cache partition first.
By the way some apps and games do not work on rooted devices for security reasons.

I understand that. That is why I clicked unroot in supersu and tried the game app, but it still wouldn't work. On my galaxy note 3 I run 5.0 lollipop and my game works fine. My phone isn't rooted and I never decided to root it and then unroot it.
Is an app smart enough to know when a device has been rooted and if are those that hack their actual game on rooted devices uses cloak or xposed or both to by pass their root?
I rather be unrooted for the sake of the game, but how does one find the stock firmware? Or is it not possible at this point?
Sorry for any confusion.

Okay. I installed or flashed ironrom to my tablet from twrp. i followed the directions it told me and I decided to pick the regular rom above the custom one that was close to stock. Then it told me that it was going to reboot; which it did. When it came back it got stuck on the same samsung loading screen so I powered it off, went back into TWRP (because powering off now isn't possible, more like restart) and I went to "Reboot " and then I clicked "power off".
I guess I'll be waiting for 10 to 15 minutes.
I Pray I did this correctly.

Why did you reboot back into twrp? You should have just let it do its thing after it rebooted.
So for any others that may happen upon this thread.
What was your solution?

I did because I thought it had to be shut down before I powered it on and waited. I realized afterwards that you probably meant to just let it sit for 10 to 15 minutes.

cant reboot after failed encryption
I was trying to encrypt my galaxy tab s, which is rooted and has lollipop 5.0. Afrer reading encryption failed. I tried to reboot in recovery via twrp. My device doesn't reboot, it just acts like its going thru the motions. Only to return to twrp recovery menu. How do I reboot the system clearing the failed encryptions. I am a noob and any suggestions would be much appreciated.

You will have to go into recovery and wipe the data and cache partition then reboot.
It may take a while to boot up after that.

Well I thought my solution was using IronRom... but i'm not too sure now.
I just got back from work and I went to turn on my tablet and it took me to the same loading screen and then after about 5 minutes it tells me that the system can't respond. It asks me to click "ok" or "wait" ... clicking either just turns my tablet off.
Now the screen has dimmed. It's turning on when it wants and sometimes it'll show me the time in the upper right hand corner, but it won't let me do anything because it's a black screen.
What does all of this mean?

I just noticed if I click the "power button" it just flashes my tablet desktop then goes back to black, but it shows me the battery percentage and the time in the upper right hand corner...

Stuck in Boot loop after weeks of normal usage

Hi.
I have a problem with my D855. My phone is rooted and runs the fulmics ROM. Everything was working fine, , on Fulmics 5.3, except than one day, I was using my phone normally and then it crashed. I saw the phone rebooting, but for some reason it got stuck. The phone tried to boot unsuccessfully until the "firmware update" went through, after what it reboots again (unsuccessfully) and so on.
At that time, I was able to access twrp, do some backup, and flash properly with a downgraded version of fulmics (from 5.3 to 4.1).
It was able to boot again and use my phone like before. Yet, after one month of usage, the same problem happened on version 4.1. The phone crashed and now cannot boot.
Any idea of where it is coming from? Should I go back to stock? Should I contact customer service?

What did you do before the phone crashes ?
I think you probably should flash the stock ROM and wait for an other crash... or not.

I haven't done anything special. I think that the first time I was playing on candy crush. The second time I was just looking at pictures in my gallery.
I was using the ROM without any tweaks or extra modules such as Xposed. Just regular use.
Update on my situation: I switched back to stock ROM and it seems to work OK for now (it has been 4 days). So I will wait and see if new problems happen. By the way, it was extremely difficult for me to get back to Stock directly from fulmics ROM. I tried several methods that I have found on xda based on LGUP or LG Flash tool without success. For some reason I was not able to connect the phone to my PC in download mode.
The only way that I found was to use a nandroid backup that I did just after rooting the phone and that was based on stock ROM.

You can also use the Stock rom flashable from twrp. So you can wipe the system partition and get a "better situation" than a nandroid backup that should be with an old version.
Or use this that has also root and other improvements.

Same problem here. Normal usage suddenly started to reboot and now it's stuck in boot loop

Coming from Fulmics too - stopped working one fine day.
Now, continues to boot-loop at the initial LG screen. Trying to get into the recovery shows me the the 'Factory Reset' screen, but beyond that leads to boot-loops again. Even the Download mode loops!
I'm at my wits end without a solution in sight.

Or use this that has also root and other improvements.

Thank you for this advice. I was able to update my stock ROM after the Nandroid backup through LGUP, but your method would have been faster.
But anyway, I am waiting to see if I am stuck with bootloops again, using non-root stock version, so I can send it to customer service if this happen again.

Are you using Fulmics ROM as well? Can you have access to TWRP? I was able to connect to a PC in the recovery mode and to transfer files before flashing, in case you need some basic backup...

prakhargr8 said:
Coming from Fulmics too - stopped working one fine day.
Now, continues to boot-loop at the initial LG screen. Trying to get into the recovery shows me the the 'Factory Reset' screen, but beyond that leads to boot-loops again. Even the Download mode loops!
I'm at my wits end without a solution in sight.

Silly question, but are you sure that you selected "Yes" when the screen asks you about factory reset? you have to press "volume down" and the "power button", since the default answer is no.

Yes, of course I was able to access TWRP successfully earlier.
Curiously enough, the phone boot-loops in regular startup, Download mode and trying to get to recovery. However, it doesn't restart itself and fall into a loop, while on the Factory Reset menu. Am I correct in assuming that the battery could not be the root cause of the overall problem? Because if it was, it would likely loop even on this Factory Reset menu as well as far as I understand.
Unfortunately, the phone restarts as soon as it lands in the Download mode so I cannot even restore to stock.
EDIT: Okay, weirdly enough it just booted and reached the homescreen before restarting again. What I did was let it charge to a 100% and tried booting while plugged in. Could it be the battery after all? Though this exact set of steps hasn't been helpful before.

Stuck at Google logo

I searched "stuck at google logo" and "stuck in bootloop on start up" and the only real suggestion I found was using Duece's bootloop tool, but I was hoping to not have to wipe all my data if ipossible.
here's my set up.
Jan factory image
latest twrp
the flash kernel 2.14
and latest magisk
nova launcher
not other mods or xposed
Getting stuck at logo has happened once or twice before, but restarting by pressing the power button has always brought it back.
Tonight, I had to hard restart 6 or 7 times before it rebooted successfully.
Any suggestions other than running the bootlooping script? I'd like to learn the manual way of fixing stuff if possible.
Thank you for any help.

Maybe try fastbooting the factory image with the -w removed out of the flash-all.bat file and then run the script. It won't wipe your data. Let the phone boot up, then go back to bootloader mode and fastboot twrp. Then you can flash the twrp zip, custom kernel, and magisk. Don't know if that'll solve your rebooting problem, but it's a start ?

On 8.0 Unlocked
Did everything you had done and got the same issue. Been over 40 minutes at the G logo with the loading thing on the bottom. Any advice on how to proceed?

Any luck with a hard restart by holding the power button down?? What exactly did you try flashing?

First attempt was done via TWRP, Second attempt was done via Magisk. With both of them the message was shown that it had completed successfully. Though, after rebooting, the OS would get stuck at the G logo.
No idea on how to proceed honestly

An attempt at installing Xposed. Both attempts after installing Xposed, doesn't allow me to get past the G logo anyhow.
I have factory restored the device a few times with the same results.

Sounds like you have tried to install a boot/dtbo that is a previous release instead of what is currently on the device. This happened to me. Flashing the correct version fixed my problem.

p.s.: outdated Android Tools could be at fault...
If it is current, there is a flashing tool called Deuce's at https://forum.xda-developers.com/pi...ol-deuces-bootloop-recovery-flashing-t3704761.
It has saved my bacon more than once while fiddling with rooting and recoveries.

I second this. Same thing happened to me. I had to reflash the previous image to get it to boot.

various issues with google variant

I've had Google phones for years now, including previous Pixel, but I just got an XL 2 yesterday and I'm regretting it.
It's Google unlocked and running June's latest image. I've experienced various app crashing on stock, and random reboots.
Then there's the rooting and flashing. I unlocked the bootloader and installed the most recent, twrp (the one verified to work on xda for roms) but can't flash anything.
My twrp either hangs on the twrp start screen, or when it does load, the touch screen doesn't work. When I can get it going, every rom I flash gives me an error on the second step. I'm flashing on slot B by the way, that's what boots up when I boot to twrp.
Lastly, I am unlocked both for flashing and flashing_critical thru adb, so I'm at a loss and seriously confused.
When I FIRST unlocked everything, I was able to flash Nitrogen rom but I got stuck at the rom splash screen.
Tldr:
-What is the Correct install method/sequence for roms?
-do the slots matter?
-is random reboots and app crashing on stock a sign of a hardware issue?

I haven't installed a custom ROM on my P2XL, so I'm running rooted stock. Anyway, for rooted stock, this is what I did.
Entered bootloader mode.
Booted into recovery using the command "fastboot boot recovery.img", where "recovery.img" is the TWRP recovery iteslf. In my case, I renamed it "taimen.img".
Flashed the TWRP installer zip needed for the P2XL (Required if intending to replace the stock recovery).
Rebooted into recovery.
Flashed a custom kernel (Recommended - resolves touch issues in TWRP).
Flashed Magisk.
6. Rebooted.
If installing a custom ROM, flash it prior to the custom kernel. Slots only matter if running stock. Random reboots and app crashes are not signs of a hardware issue.

Ya know my friend, after our conversation yesterday, and your questions in the nitrogen thread, and now random reboots and app crashes, I think it's time to consider a factory reset. You shouldn't be having those problems on a stock setup. If that's not successful, then I would definitely consider an RMA. Just my 2 cents worth :good:

I agree. I got it used tho which is an issue.

Just so you know, I got the rom to flash finally, but it's stuck at the rom splash screen during first boot. I'm going to leave it and hope it eventually boots up.

If it doesn't after 5 minutes, do a hard restart with the power button. If that doesn't work, then reboot to twrp and flash the rom and twrp installer zip again.

Ok cool thanks. I relocked bootloader last night and went back to stock. Unlocked it all this morning from my work computer and different unlock app. So here's hoping.

I finally got everything to work. My vendor image is a mismatch but I could just flash junes and be done with it, right?

What did you do to get it to work? You could just flash the June vendor.img to both slots. If you keep getting a vendor mismatch, probably nothing to worry about according to the Dev of nitrogen.

Different machine, cable and unlocking tool.
But I went to bone stock with locked bootloader, then flashed the newest twrp with the newest all in one tool. Was on slot A so wiped everything and flashed rom plus twrp again. I rebooted system to slot B, but then it just hung at the rom splash screen.
So I did it all over on slot A, ignored the "no os installed" message and booted anyway. Then it fired up. Rebooting into twrp from there took me to B, which is where I need to be for an image file or root.
So yea, thanks for the help.

I'm having this issue also. I tried flashing nitrogen, it hung. I tried to go back with factory reset Img and nothing happens in adb. Flashed the may img and it wouldn't boot all the way up. Now I'm stuck in bootloader trying to figure this all out. Seems like nothing in doing is working. I can get recovery to boot, but no files inside so idk. Tried to sideloadb nitrogen, but it said adb out of date for device when sdk is fully updated.

You didn't mention the out of date message in your other post, but uninstall SDK and then download the stand-alone adb/fastboot binaries from May of this year. Dump that in a folder (eg. c:\adb) and put that folder in your path statement. Manually flash the full factory image without modifying flash-all.bat. Post your screeen if you have any errors. :good:

Google knows the date the phone was purchased based on imei number and honors their warranty by date, not owner. Unless it was blacklisted.
