[Q] Nexus 6 stuck in bootloop

Ok so, this is my first post on xda, and because my (sprint) Nexus 6 is stuck on a boot loop. When powered on, goes to googles boot animation, then says "Android is starting... optimizing apps # of 127, and then once it reaches the end, it just goes into the animation again. I somehow have usb debugging disabled, and oem locked. I have no idea what i did to cause this, but esentially I unlocked the phone, and rooted it, and then i tried to disable encryption, and thats where things went south. clearing chache does not help, niether does factory reset. Attempts at flashing factory images are fails. even the guy at sprint cant do it. Besides fixing it, my only other option is to send it in to google and get a reaplacement...for $200. PLease help me solve this issue and i will be eternally grateful :3

OK. So...do u know how to use fastboot? If yes...do a fastboot format data and fastboot format cache..also...do u have stock recovery or twrp?

I got that bootloop when I flashed a bad boot image. Easily fixed by flashing a good one...
But, let's clarify a couple of things:
Did you relock your bootloader while flashing?
Do you have a custom recovery (TWRP)?
If the answer to both of those are "yes", you might get out of this by using these commands:
fastboot format userdata
fastboot format cache
This will allow you to enter TWRP and restore a backup or flash a ROM.
If you didn't relock your bootloader you shouldn't have any problems flashing. Clarify what your trying to do, please (are you using a toolkit, etc).
If the answers are 1-yes and 2-no, then your probably SOL.

SOL = "S**t Out of Luck".
There is currently no know way of fixing it.
Your only avenue is to RMA it.

Oneplus 3t bootloop. (I think)

Hello, I rooted, and installed custom recovery on my 1+3t. And the new update came out. I decided to give it a shot. Long story short. I locked my bootloader. And when I try to boot it up. It shows logo for one second, vibrates, and is stuck in that bootloop. I can get into recovery, and fastboot, but bootloader is locked. Any ideas?

Use recovery unbrick tool.
And don't lock your bootloader when you're going to flash any kind of mod, like Magisk.

You can unlock bootloader if you have activated oem unlock and usb debugging in the developer option. Then you are good to go for custom recovery..

You should never re-lock your bootloader after you flash anything not signed by OnePlus. Your device can never be booted up and only can be fixed if you use the unbrick tool by Qualcomm.

My thoughts exactly.
To the OP, you don't need to lock the bootloader to update this device. And you should never lock the bootloader with mods on the phone (TWRP, root, etc.).
Good rule of thumb, is to read up before doing an update like this. Would have saved you a lot of hardship, as all the info is here on XDA for those that care to search and read.

Moto g6 hard brick after ota update

Hi everyone. I have a moto g6 and I updated a few weeks ago, but the thing is that when I was flashing the stock (the 8.0 version becuase it doesn´t exist a 9.0 yet) rom via fastboot I get an error about "downgrade security", after that I try to unlock the bootloader and I found that I cant get into the os and the recovery, it apears an error "failed load kernel" and gets into the fastboot mode. I try to unlock the bootloader via adb but i can´t because i can´t get in to the recovery, only fastboot mode. I try many ways to fix this but I don´t found anything yet.

Hold power and volume down til reboot into "bootloader" mode, plug usb-c cable to PC, then reflash later stock rom

Just power up directly to bootloader holding power + vol down, then reflash the latest official firmware for your device. As long as it is the official firmware for your device you don't need to unlock bootloader.
BUT if you brick it with an updated bootloader thats more recent that the OG firmware available for your device, sadly you have a cute paperweight until an official firmware with a more up to date bootloader is available. It happend once to me with a G4 Play have the device useless for a good 2 months until a firmware with a new bootloader was available. It sucks.

You have to go to the service center.
Hey msobarzoe13, I am using moto g6 and from India. When android p soak test was leaked as everyone out there, I tried it. It was good except for some network issues. So I decided to revert back to the stock firmware. I downloaded the OS and flashed it and faced the same issue. I tried several times but no luck. I was not even able to unlock the bootloader because I didn't turn on OEM unlock under settings. So I took it to the service center. The best part is by installing Beta your warranty is void. So I did it through the service center. They told Moto G6 series is very secured so flashing it with a leaked software is prevented. I don't know why. So don't take a further risk, take it to the service center.

What you mean with "OG firmware" and what if the motorola is totally hardbricked? I mean not able to go to bootloader or recovery or even fastboot because he didnt turn on android debugging oem?

If your bootloader is still locked just take it to a moto service centre, I also tried downgrading and took it to service centre they fixed it

I have also hard bricked my moto g6 while updating. There was an OTA update and i started update without noticing my battery percentage. Now i have hard bricked dead moto g6. There is no response at all. Only life in my device is that it is detected as Qualcomm HS-USB QLoader 9008 in pc.

My Moto G6 went into Hard Brick after downgrade and upgrade, does not go into download mode and does not turn on, just flashes the led.
Does anyone have a solution.
Thanks.

Same problem with me also. It may be detected as qualcomm hs-usb qloader 9008 while you connect in pc. If that is the problem than we need blank flash file which is not available right now. Either we have to send our device to service center for motherboard replacement or we need to wait for blank flash file which is not possible to come because these files are sensitive to motorola. another solution is if some one provide me mmcblk0.img of moto g6 than i might be able to boot it from sd card and may revive it again.

My Moto G6 Ali got hardbricked also plzzz help anyone solved it or have blankflash HE
Do anyone got any solution regarding this then plzzz help

Stuck on bootloop, can't pass even after flashing

So, i got a second hand mi 5 last week. Seller told me that it had software issue and I thought I could fix it. Because it was really cheap.
The device was stuck on bootloop when I had it. But I was able to open mi recovery and fast boot menus. i tried many options to flash a stable stock rom. The most useful one was to flash via XiaomiTool v2. It says successfully flashed and reboots but stuck on bootloop every time. (Tried few times already).
the bootloader is locked and no mi accounts binded to the device. Computer detects the device successfully.
I tried adb commands as well, but since bootloader is locked i couldn't get any further to flash or wipe.
Any useful suggestions?

Can you still access to fastboot mode?
If so, you need fastboot oem unlock to unlock bootloader first, before anything else.

Question Big Problem Need some Help

Hey i spend today a lot of time to tried to fix my bricked Redmi Note 10 5G.

First problem i have is the dm-verity corrupt.
So i read and tried this

Becuase the bootloader is locked again warrenty only the dm-verification message is there.
Do gonna say i updated my phone and now its not booting anymore.
Or do you or maybe some one do have an tutorial program or tool to fix it.

Download ROM for your phone and extract to desktop. Reboot to fastboot and open flashall.bat. it should run firmware through and reflash phone completely. Boot phone and on boot screen keep pressing power so phone can boot and bypass DM Verity error. Once booted reboot into fastboot again and enter fastboot oem cdms. Reboot phone and DM Verity should be gone.

we repeats same anawers continuosly.i dont understand why some users decide to mod their devices, if they dont know how to use Google, and don't understand how to follow the flashing guides step by step. and finally after flashing custom rom, they ask how back to stock

Get what you are saying, think there is at least 8 threads on same topic.

Hey thanks for the answers and the things i could tried to fix my phone.
im not a noob with rooting and flashing android phones before i do flasshong or rooting and the other stuff i always read and check the xda forum before i do.
With other android phones that i had before i made some misstakes before but like a bootloop or something else that the phone not was booting but always i can fix the phone.
So the problem what i had with my Redmi note 10 5G and not one solution that i found on xda or something that maube could fix the problem nothing could fix it.
So i a couple of week ago i went to the reseller and they send it to a repair center.
I think the coudnt also fix it because the did a boardswap.
I think if they cam fix it with a tool or software and reflashing the phone they did.
Now i wait some time before i go rooting or flashing stuff on my phone i hope there will be good twrp so thning go musch easier in the future to fix stuuf like (DM-VERITY Corruption.

twrp is not necessary. fix dm-verity is easy. the are MANY MANY MANY post where is explained how to do. root new phones is dofferent but not complicated. magisk works fine if installed following the latest guides. it's impossible damage mainbord after a root procedure. sure you didnt follow the guides with attention. i have rooted my global phone many times without problems. simply you have made a bad flash of vbmeta or product partition. you made a big mistake, cause this devices can be rooted without brick
