    Stuck in bootloader, this has happened 3 times in a month. Why does the OnePlus get stuck on boot up with tbe message Boot Reason: init_user0_failed?

    Just a simple restart of the phone and it boots up like this

    The three times it has done this the way I get out is boot into fastboot I believe or it could be recovery as u suggested I can't remember but the problem keeps occuring. Three times in a month it has booted into this state from nothing more than a simple restart. I've not fiddled with the phone at all

    A simple restart triggers it, I can't remember how I get it back on but I fiddle through the options and luckily within a submenu I found something that worked

    I have the same problem every time I restart the phone. It usually starts working after 3 reboots

    Following, this is happening to me as well on every manual restart and I have to select wipe cache, power off or reboot again and again until eventually it lets me in. So annoying, this is my second OnePlus phone and I thought I found my people but this, along with Bluetooth issues, has me close to jumping ship for good. OnePlus 9 Pro

    So annoying with the fact that oneplus keeps ignoring the issue and dont come out with a solution. I have two oneplus 8t with the same issue. i have talked to oneplus support and we arranged a remote session in which we completely erase the phones with flashing the rom. Then we get them to work for a month, now after latest update the issue is back and i'm "fighting with the phone to get it to boot"

    I have had 7 Pro, 8 Pro and 9 Pro. Never happened. I have no way to tell how common this is or why it happens to some.

    I have had this issue with my oneplus 8 pro since day one. Some people say to wipe the cache but when I do it it then gives an error it could not decrypt the contents of the phone and is permanently bricked. The only way to save it is to keep rebooting and praying you wont have to reset the phone. I have found that after placing the phone near an AC or somewhere cold it booted up again, but that could just be a coincidence. Either way, being terrified of the battery draining to 0 and being unable to ever turn off my phone is not a proper way to live. God forbid you forget to charge it one day and then poof 256 gb of stuff is gone. This is my last oneplus phone for sure

    You might want to reach out to support and get the device checked.

    Always keep the most important files on 2 different storage locations. Like automatic sync online, a copy on your PC, USB drive or whatever. It protects against more data losses than just boot issues (theft, drops and breaking the phone...)

    Same issue here. Right after installing an update (with whatsapp fix in releasenotes) I get into a reboot loop. Exact same boot reason as the first post. Can only erase all data and try to recover it from backups... This is not what I expect from a flagship killer.

    It's a regular issue from what I have seen on XDA and Reddit, going all the way back to the 6T.🤔

    Maybe I'm lucky or others unlucky? Who knows.
    Anyone pointed out a theory of the root cause of this?

    When an issue passes through 4 generations of devices the reason why is very obvious.

    I had 3 generations of Oneplus without this. Always on open beta when I had the chance. Often testing stuff and rebooting a lot.
    Someone else gets it 3 times a month. Does not really make it obvious to me.

    Must be some type of trigger/fault behind this that I never had. All I really get when searching on it is that it seems fairly isolated to Oneplus.

    I see several claims of "this and that update" causing it and many saying they never had it. Even Magisk gets the blame according to some. Even articles has been written about it making the conclusion that an update caused it and even claiming wiping caches was the solution.
    But since it often seems to be a returning issue for those that got it once while some never have it, the details of the cause is not that very clear.
