    *hard RESET in the title. Excuse me, I don't speak English well.

    My phone just turned off because the battery was low. When I plugged it in, this screen appeared and I have no idea what to do to restart it normally. I tried holding down the power button but it doesn't do any good. Does anyone know how to help me? I don't want to do a hard reset [e]1f62d[/e]
    (I didn't press any keys/key combo - I just plugged it into charging when the phone turned off) [e]1f494[/e]

    hi, phone tried to go into recovery mode. don't ever click forgot password. press power button and volume up button simultaneously for 10-15 seconds to turn your phone normally.

    I've tried that as well, I'm starting to feel desperate now [e]1f62d[/e]
    The screen goes black when I press both the power and volume buttons but then it doesn't work when I normally try to start it. It keeps bringing me back to that screen in the picture [e]1f614[/e]

    did you only press them until phone shut off and booted up again?

    Yes. After, like, 6/7 seconds of pression the screen goes black, then the phone vibrates, it seems to reboot, then that screen reappears.

    okay, try to enter password/pin if you had enabled it in OS, same pin/password applies here too, then select language English, then select exit option, then reboot option.

    No dice. Amen.
    After entering the PIN it would just make me choose between NO and OK, saying I would lose my data. I put OK because by then I was desperate.

    I will definitely never let my phone battery go down to zero again (this is the second time this has happened to me, I have no idea how I solved it the first time).

    Now I'm going to go cry in the corner.
    Thanks for the help, though [e]2665[/e]️

    so sorry, it didn't help you much.
    when you are done with setup'ing the phone, do local upgrade 2 times! the same build as you're on.

    I'm having this problem the general feeling is it's from dodgy updates OnePlus are producing. Anyway there's two options that so far always seem to work when I get in this position which is a fair bit recently. Clear cache and fastboot mode.

    If you put your pin in that you use to enter your phone in the password bit they'll be an option to click 'wipe data and cache' click that then click the clear cache button this should then reboot the phone hopefully normally however sometimes it doesn't work if that doesn't work do same process again enter password etc, then go advanced and go 'reboot to fastboot' this works for me and I've so far not had to do the clear data option!!!

    Yeah seems to be the thing that does sort it I can understand where Eggzorcist is coming from this is my first one plus phone and panicked when It first happened still panic now 😂but a little google seems to happen on most one plus phones and people blame the software but that these fixes clear cache (usually after an update) or fast boot tends to boot phone up normally. I must admit I'm skeptical about buying another one plus again tempted after 12 months or so of this to sack it off and look elsewhere like oppo or Xiaomi or Samsung or something as this recovery mode really shouldn't be happening as much as it does to all OnePlus phones

    This is not a OnePlus problem and please read other posts on the same subject matter. This is a security feature implemented by Android that I think started with Android 9 (I'm sure there's someone else in here who can correct me on when it was first implemented). Google requires encrypting certain parts of the recovery or boot up process. The only way around it is to enter the correct pin or password (case sensitive). If it's been corrupted or entered incorrectly it won't work. I haven't had this issue so it's likely user error, low disk space, or some other oddity.

    Honestly this has happened to me twice and only with the battery at zero %.
    I don't know what PIN to enter, I entered the one that unlocks my phone because I don't have others, maybe that was the mistake.
    No, I didn't get any options to clear the cache or anything, the next screen always just said something like, "This option will clear all your data, do you want to proceed? No or OK". Maybe it's because the PIN wasn't right (and maybe I saved myself the first time because I entered the right one) but honestly at this point I don't know WHAT I may have entered the first time, since the only code I have is the phone unlock code.

    Also, English is not my native language. Before writing here, in a panic, at 1am I OBVIOUSLY googled it but only found information about a similar problem that happened years ago on the OnePlus Nord. Frankly, I didn't even know WHAT to look for, which is why I asked for help here.
    Since you clearly know more about this than I do, what should I do to prevent it from happening again in the future?

    I'm having the same issue on my oneplus 9 pro :(

    Left phone charging overnight and woke up this morning, the phone was in this mode where he ask for password and once you enter it is threatens you that it will wipe all your data if you go any further.

    This is the second major issue with my oneplus 9 pro. Before I had a oneplus 6, owned for 3 years and had 0 issues, I start think that this type oneplus sent me faulty phone :(
