Need help, stuck at logo and can't hard reset.

PROBLEM SOLVED.
So at first I used Kingroot to rood my device, and it failed, but then i just realized few days later that Kingroot was installed and used root checker to check and said that it does have root access. After that decided to change the Kingroot to SuperSU by following this video https://www.youtube.com/watch?v=WevWdErXWy4 (It's the SuperSU Me app). I then updated SuperSU binaries and restarted the phone, and now its stuck at the loading screen. I tried hard resetting my phone but it would only show the screen with the android logo and shapes in its belly for about 2 second and go back to the stuck logo screen. Now I'm wondering if there's any fix for it, and if there's no fix then I'm going to try resetting it through this http://lgg3root.com/lg-g3-root/how-to-unrootunbrick-lg-g3/ guide and I was wondering if I should download and use the bell stock factory firmware (I have a virgin mobile version).
Edit: fixed to be more clear.

if you can get into recovery you can probably do it without unbricking. to you have stock recovery or twrp or what? If you have stock recovery then boot into recovery and just run it and itll hard reset your phone, if you have twrp or something just download the flashable rom of your choice (there are stock modded roms too if you like stock) put it on an sdcard and wipe and install that rom.
if you don't know how to get into recovery then make sure your phone is off (if ur not sure do a battery pull and put it back in). hold volume down and power button until the screen comes on. when it comes on let go of vol down and power and then push vol and power again and hold again until you see the writing)
btw if you do a stock recovery hard wipe then you will lose root.

I also faced this problem...

Problem solved. I just flashed the stock firmware onto my phone and it fixed the stuck on logo problem.

At a loss... SM-920P, MM, continuous reboot loop no matter what

I upgraded to MM back the beginning of the month, tripped my Knox bit (I had rooted via PingPong root on Lollipop), but I was eager to go to MM and try Xposed so I could improve the horrible battery life.
I had the system working fine, rooted using CFAR, and no problems. Randomly, about a week ago, it just "lost" root. I wasn't sure why, and CFAR from Odin wouldn't bring it back. I did a flash with SuperSU in TRWP yesterday and it worked, and I did a NANDroid backup, saved it to my computer, and installed Xposed... On a stock ROM.
And my phone has been a continuously rebooting brick ever since, no matter what I do.
So, I've tried everything I can think of. Because my data was completely backed up, I did a complete wipe, and nothing. I tried flashing the Xposed-uninstaller.zip and that supposedly worked, but the phone reboots about 53 seconds after it starts up, continuously, no matter what.
I've tried the default MM firmware, tried letting it go through it's paces on its own (but it just reboots every 53-57 seconds), and also tried with a fresh clean default MM ROM, which does dump TRWP, then restart into the default bootloader, have it dump the cache and do a complete re-wipe, and nothing. Still restarts.
With the stock MM firmware load, the first boot it always stops at 32%, reboots, and when it comes back up it sometimes makes it through "optimizing xx of 30 applications" but always reboots and comes back to it over and over, ad infinitum. Sometimes it makes it to 30, usually it doesn't, but it always fails, reboots, and comes back to the same menu on a stock ROM.
ADP and MTP in TRWP work fine, and all my data is backed up. So, I'm willing to do anything to the device; nothing left on it to care about (I already tried NAND erase in Odin and format partitions in TRWP). It still continuously reboots at around 53 seconds.
I've also tried custom ROMs loaded up from TRWP (Renegade 1.1 and TeamSPR V3). They apparently load - everything looks/works great from inside TRWP - then invariably they reboot at about the 53 second mark. Can't even get Renegade past the boot screen.
Nothing was done hardware-wise to break it; the Knox bit flipped three weeks ago, and the SuperSU upgrade had been working fine. The action that killed it was attempting to install the Xposed framework on a default ROM that only had SuperSU installed. But I've since installed a default ROM and ran the Xposed uninstall to no avail. The uninstall Zip in TRWP gave all the right responses that it worked, but it still rebooted 53 seconds after restart. Continuously.
I don't even know how to go back to Lollipop because attempts to load G920PVPU1AOCF in Odin gives me an immediate failure of "SW REV. CHECK FAIL. DEVICE: 3, BINARY: 1," so downgrading appears to be out of the question.
Someone has to have seen something like this before or there's something I'm missing. About the only thing I can think of is to try a custom ROM install and force the Xposed framework again without even letting it boot up (because it won't anyway) from a TRWP install. I'm going to attempt that while hopefully someone else comes up with ideas for me...

rebooting
people have had luck letting their phone battery die completely and rebooting after charging just a little bit. make sure its completely discharged before rebooting

Stick it in Odin mode and let it die, once it gets to the point where you cannot turn it on anymore, it's good :good:

Updated Android O stuck on G boot screen

Hey all,
So I updated my pixel xl to Android O, and then used the modified TWRP to flash Super Su, SUhide. The phone booted up and everything was perfect. It was a little sluggish so I decided to do a full factory reset... again, phone reset, booted perfectly. I then restored all my apps from the google play store cloud... phone was functioning fine.
I went to reboot the phone after a while... and now the phone is stuck on the G logo after the bouncing dots... and just continues to load.
It's been like that for over 20 minutes.
Is this normal? Anyway I can fix this?
Thanks!

I have the same exact issue after following the exact process described above. After a weekend of frustration, I was thrilled to see this post, but then bummed there are no suggestions. There is no way I can get it back to recovery, no matter what power/volume combination I try. The phone is not detectable by ADB either, so unless a kind soul has a suggestion, there seems to be nothing to do except let the battery die and hope.

Umm boot into bootloader and flash stock boot.img and system.img?

I would love to do that, but how is it possible if there is no power or volume button combination that can get me off of the Google boot screen and into bootloader?

Have you tried Power + volume down ? It'll turn off after release power button only. That or let the battery die and when you try to plug it up next time leave vol down pressed.

I have tried that, thank you. I will let battery die and do the Volume Down method you suggest, and report back.

That did the trick. Back to stock 8.0.0, and hoping to find a stable root method that doesn't hang-up on the first reboot. Thanks for the help!

First of all. Hold the power button for about 20 secs and the phone will reboot.
Hold vol - and you are straight to bootloader.
Second flash full factory to both slots.
And third stop using the - w solution when you are coming from another rom or a different stock version. We had this problems on other forums and it was every time - w or not flashing both slots. I know for many people there will be no problem but some apps are just misbehaving when you do so. And they are causing reboots and bootloops.

OK, thank you! I am not familiar with the -w method. This is a new Pixel XL I received from Google to replace a nexus 6p with a bootloader issue. I made the mistake of not attempting this before it updated from 7.1.2 to 8.0.0, or it may have been a different story.
So I have the the phone restored to 8.0.0 and was going to attempt root. But I didn't realize there are two slots to flash. I simply ran flash-all.bat and the phone came back up. So I guess I'd have to move the Sept security stock image over to the phone along with the SU, SU Config (which may not be needed if on 8.0.0?), and Su Hide. Then I boot up TWRP 3.1.1 and flash stock image to both slots, reboot, then get back into TWRP and run the SU, then SU Hide on *both* slots?
Thanks!
Janx

Run flashall.bat on the slot you are now in. Reboot to system
Back to bootloader. Switch slots through fastboot
fastboot --set-active=_b
fasboot reboot bootloader
Now you should be on the other slot
Flashall.bat
Reboot to system
Back to bootloader
fastboot boot twrp.img (latest)
In twrp put latest su or in my case magisk 14.2, twrp zip on device.
If you use su just flash it
If you use magisk. Flash magisk, flash twrp.zip and magisk again. With magisk twrp will stick.
Reboot and you are good to go.
If you want a kernel you have to flash twrp and magisk after again.

Thank you! I will be able to perform this sequence in a few hours and will report back. :good:

Ok. Will be in bed than. If you have any problems give me a PM and we can do it together via hangouts.

Update: I successfully flashed A & B, got to the step where I flash Magisk 14.2. It finished unmounting partitions, but when updating partition details fails, "failed to mount '/system' (device or resource busy)...done
It said successfully installed, so I flashed twrp to the boot image, flashed magisk again, and it is now rebooting endlessly. Wrong place to flash the twrp image I'm guessing?
EDIT: Just noticed your message, good night - thanks again. I'm working through it and will take you up on your kind offer should I not find success.
I did a 'flash-all.sh' on both A and B again, copying over my old phone, then will attempt to gain root by booting into TWRP 3.1.1, installing "SR3-SuperSU-v2.82-SR3-20170813133244", reboot bootloader, go into TWRP again and then install "UPDATE-suhide-v1.08-20170815171034"
EDIT #2: EDIT #2: Stable root achieved using newer versions of files "SR5-SuperSU-v2.82-SR5-20171001224502" & after booting, applying "UPDATE-suhide-v1.09-20171001222116". So far it has survived several reboots, so I'm hoping it's all good now.

Phone turns on, HTC logo shows up, recovery works but phone DOES NOT BOOT

My phone was a bit erratic and I decided to reboot it. Before that I installed a new Magisk Manager version, updated a module and uninstalled another (I should've had done one step a time, I never learn). After all this I rebooted and my phone no longer booted. the HTC logo shows up and then the screen becomes blank and nothing shows up.
I can reboot it pressing the Power + Volume Down buttons for 10-15 seconds, I can boot to bootloader, dowload mode and and recovery. The phone charges just fine in recovery or powered down. If I let it try to boot for a while and attempt "adb devices", nothing shows up, so I can't invoke "adb logcat" and see if it's in a boot loop or something. It's hard to debug and understand what's wrong.
Flashed Magisk Uninstaller, still doesn't boot. Another mistake is that I don't have a backup, yes, I'm an idiot. I don't understand why I keep living on the edge like this...
I use MaximusHD ROM and I'm now thinking of reinstalling this on top of my current installation to see if it fixes anything, as a last resort because I can't think of anything else. Thoughts?

I can't speak to your specific issue with Magisk but you should easily be able to return to stock by flashing Maximus, or by running an RUU from your sdcard. The ruu will wipe your phone completely

Tried to reflash Maximus, didn't work, still didn't boot. Backed up everything I could and wiped everything, I'm now on Lineage OS 16.0. Thanks for your reply.

Stuck in boot loop even after factory reset. Able to get into bootloader and recovery

Hoping for some help or alternatives to fix my fiancee's Pixel XL. Last night the phone just kept flashing the 'G' logo on for 10 seconds, off for 10 seconds. She said the phone was close to dying before it happened, and I imagine it probably ended up draining the battery afterwards with the constant bootloop. Plugged it in all night but the charging screen didn't come up and would just stay in the bootloop. I could get it into the boot loader (power button and volume down), but it wouldn't go into recovery mode and instead would go right back to the boot loop.
So I tried a battery pack to charge it and it still didn't show charging, but I was able to get it into recovery mode eventually, but still boot loop afterwards. At one point, after leaving it on boot loader menu while attempting to charge, it eventually just tried to start itself and made its way to the second Google splash screen after the main G logo. Looked like it froze there though and I couldn't get it to that point again.
On my way to work this morning I tried plugging it into my car's USB port after powering off from the boot loader, and this time I kept flashing that it was charging (looked like it was 3/4 charged but not sure how accurate that is). So I got into recovery again and tried 3 factory resets consecutively. Still bootloop after attempting a startup afterwards. There was a similar issue a couple weeks ago where it looked like it was stuck in a bootloop, but it turned out the phone actually was dead that time and the charger wasn't working. Once we switched chargers it booted right up.
Any other suggestions or possibilities? I don't have much troubleshooting experience otherwise. Phone is fully stock, Google Fi. Any other info I can provide please let me know!

well, i'm not sure if it makes a difference, but now for some reason i can't get into recovery mode again. just goes into the boot loop. It also goes into the boot loop as soon as I plug the phone in to charge.

I assume you can't get into the bootloader using power and volume down buttons?

I have always been about to get into the boot loader. Actually i can get into recovery again as well. Seems if i let it sit for a while it'll go to recovery again. Maybe heat related.

My OG Pixel did the same thing to me one morning. I tried everything to revive my pixel but nothing worked. I did some digging and it turns out there is an issue with the storage on the phone. It's just a old fancy paper weight.

If you can get into recovery, have you tried to sideload a full ota.zip (not an update)?

I haven't. I see that Google has all the ota's on their site. Is there a specific one that i might want to try? The same one? Go back a few? Will i even be able to sideload if my phone is fully stock?
Edit: sideload adb successfully but no change. I loaded the 6-5 ota which was what i already had.

Sounds as if it's time to just try stuff and see what sticks. Regarding using an ota, it works if you are stock, and I sideload it even if I have installed majisk or installed another kernel. It typically works for me with fewer chances of blowing things up than flashing a stock image. Regarding what to try next, you may have already gone into recovery to check the install function to see if your storage still appears and try to flash anything that worked in the past; if you have a backup in twrp you could try to restore it; you could wipe cache and dahlvik; or even sideload an earlier ota version that worked. Since the 6-5 ota did not work nothing really jumps out to me as obvious. One final caveat, I once had to reboot a sideloaded ota a second time before my pixel booted properly. If I think of something else I'll post again.

I took it to ubreakifix and they told me that this is indeed a known issue with pixel xl's that they all suffered from a faulty motherboard and that is indeed the cause here. Said he thought there was actually a class action about it so I'll have to look into it. Really pisses me off that Google repeatedly told me it's not a known issue when their authorized repair center says it is.
Anyway i have a warranty with Upsie that I'm hoping to get this replaced with. We'll see.

Good luck

I'm assuming you tried booting into twrp recovery, going to reboot, and picked slot A ( or B if already in A) to reboot to and then rebooted system? A lot of the times simply switching slots from recovery and then rebooting is the fix. At least for me.

手机早期经历的情况得说明一下。root没有？Twrp是谁的？

Also, for anyone else having this issue, try rebooting into the bootloader. Connect to PC, and try fastboot --set-active=a
If this doesn't work, try booting back into your recovery image using fastboot boot *whatever you named your TWRP recovery image* and then flashing your twrp.zip again in recovery, and when rebooting if you're in slot B choose slot A in recovery to boot into.
Also keep in mind in Windows 10, it uses Powershell, so commands have to be typed in .\fastboot not just fastboot or it won't take it.
