As said in the title, I want to root my phone without wiping it, because, well, I don't want to spend a ton of time setting it up again (you can't backup installed apps)
No you absolutely can't. When you flip oem unlock and fastboot flashing unlock it automatically factory resets device. No way around. I did from the get go so I had original data.

Hi,
My friends Samsung nexus s is stuck on the X screen. since the phone is on stock rom and no recovery installed and he doesnt want to root his phone and wants all his previous data back, what should i do to get back in orignal state without loosing data?
Well, if you unlock the booloader, then his data is gonna be lost anyways because unlocking the bootloader will factory reset the phone. The only way to get his phone working again is to unlock bootloader, and flash the firmware images, or a custom rom through recovery. Your friend is going to have to accept the change on his phone and data lost. Sorry, but I can't think of no other way to restore it WITHOUT losing data.
I just unlocked the bootloader to install twrp and maybe magisk i wanted to also try the Android P dev preview. but i know having a unlocked bootloader is a security risk also your get that warnign message at boot which makes booting up longer,is there a way to lock and unlock without losing data if im root.
Unlocking and locking wipes all data by design.

Is there a way to make the device secure with it having a unlocked bootloader?
With an unlocked bootloader, anyone can install a factory image, which wipes all your locks and your google account (and, therefore, defeats FRP), which is what makes it insecure. The only way to avoid that is to have a locked bootloader (and USB debugging off). (And I've seen reports here that unlocking the bootloader, installing TWRP and Magisk, then locking the bootloader, results in a hard brick (meaning buying another phone, because Google won't replace it)
Run with the unlocked booloader, don't ever leave the phone off your person and have "insurance" that replaces stolen (and possibly lost) phones.
Hey, i have android 10 stable installed in my phone. Just before i updated my phone (while i still was on 9.0.9), i also unlocked my bootloader, nothing else, no twrp or root. Now i would like to relock my phone again, because google pay is not working anymore, and im not willing to root my phone, because updating problems all the time etc. so can i relock my bootloader just by using command "fastboot oem lock" on fastboot mode? or do i have to do something else before that? also, is there possibility to brick phone somehow? if so, is there a way to fix it, while using OOS with android 10? i know this is stupid question but i hope someone could anwer it. Its not first time, when something is changed due new android update, and all previous guides are wrong.. =/
only reason i unlocked my phone, was that when i had oneplus 1, it bricked somehow oneday, and only way to get it back working, was empying whole phone, but there was possibility to recover data, if bootloader is unlocked, but i didnt have that, so i lost everything.. so i unlocked this one, to prevent that problem, but now i have new, because Android Pay is not working..
I think you can use "Fastboot oem lock" as always, but it will wipe all your data (It's no way to skip that). I think it won't brick your phone
Yes, it won't brick your phone, just wipe your data.
Relocking succeed, thank you..
Hello. What's the easiest way to backup everything (and I mean everything, including detailed app data) before unlocking my bootloader? I want to flash a custom kernel with minimum modifications to anything else, and obviously I want to take a backup of everything before I lose them with the unlock process, but I haven't been able to find a way to do so on a stock ROM that's not even rooted.
Or is there a way to root my phone before I unlock it?
I've never had a OnePlus device before, so here I am, asking dumb questions. :silly:
Also, one more question (in three parts, sorry!): since some of the newer apps, especially banking apps, have started using stricter safety procedures, they can detect an unlocked (or even merely rooted) device, and so they don't work. 1) Is there any way I can use a custom kernel on a locked (or relocked) bootloader? 2) Is it possible to use a custom kernel on an unlocked phone that's not rooted? 3) If neither of the two is possible, how can I prevent said apps from detecting my unlocked bootloader and rooted phone?
Thank you very much in advance for taking the time to answer all of my questions.
I opened up the developer options on my Moto G Stylus and went under OEM Unlocking and selected the allow the bootloader to be unlocked option. That was either last week or a few weeks ago because I wanted to root it and put a custom rom on it. I didn't rooted it yet because I'm not sure what roms are good, I only had cyanogin mod roms on my other phones and I'm not sure which rom is the safest and best to use so I still use the stock rom. I turned on Pandora to play music before I went to sleep. When I woke up my phone was in some kind of recovery mode and said something like the operating system failed to boot. Two options were available, 1- to try booting again, and 2-factory reset the phone which would erase all data. I selected 1, and my phone booted up. Could this be because the bootloader is unlocked? Does having the bootloader unlocked leave it suspectable to being hacked? Could my phone have been hacked?
Switching OEM Unlocking is not enough to unlock, you then must on motorola unlock webpage paste code from your phone and, wait for unlock code in email, via fastboot with this unlock code doing finaly real umlocking...

Would selecting the bootloader option to be unlocked in the developer options make my phone more vulnerable to be hacked?
A few hours later my phone did the same thing and went into recovery mode saying that my phone could not load the OS and might be infected or something. I had the same options to either try to load the OS again or factory data reset the phone. How could this happen?
I factory data reset my phone this time. I just hope I don't have some kind of malware.
Mine was hacked like this. Changed stuff so it won't boot back to original. Got into system files and remote control my phone. Is there a way to get back to original without computer? It's useless now
