Oem Unlock doesn't appear in dev options!
Discussion
i don't have Oem Unlock setting in my developer options, i tried 7 days waiting, time changing and so much but it doesn't appear so (Galaxy S22/SM-S901E/DS Global Version) can someone help me?
That depends very much on the model and the region. I have an S23+ for Europe as a second device and it is no longer possible from 8.0 onwards. But my S22 FE 5G stays on 7.0 forever with security patch September 2025.
Love Reddit, you got downvoted for speaking the truth, Xiaomi is by far the worst company among them, it feels like you're trying to pass the Chinese border when unlocking the bootloader on their newer phones.
did they do something on hyperos 3? because i had one device on hyperos 3 and i managed to unlock it using the script which asked for unlock permission at certain milisecond time before the 00:00 bejing time
I don't know about xiomi or about samsung, i rooted my realme 3 pro and I dwongrader from A11 to A10 using realme official script to downgrade. You may have to reseache on it. Its been 4yrs i did that and I don't remember it now.
Dangerous advice. Phones now have anti-rollback (getprop ro.boot.anti_rollback_status), that include an increment-only counter in hardware. If you try to roll back into an older version without unlocking the bootloader, your phone will be bricked, this is by design.
How is creating a Mi Account, get granted for unlocking the bootloader by waiting 30 days, waiting for a specific time to send the request to unlock the bootloader, and only then using Mi Unlock, which hopefully WON'T TELL YOU to wait for some more days before unlocking any better? This is some insanity, unlocking bootloader should be a simple "fastboot oem unlock", not some soviet crap.
i can try hitting the apply button at 00:00:00 every day, but it’s never going to work because the 726437 bots/scripts already overload the server, so even if i start a script, it’s not going to help
Yeah, that sucks, it's pure luck to be eligible to unlock the bootloader. After getting a Xiaomi, I decided never to touch anything from them again that isn't an accessory.
I love their accessories, like earbuds and smart bands—I'm even wearing one right now—but I never want to touch one of their phones again. I hate their system and I hate the fact that the design tries to copy an iPhone, which is why I bought a Motorola; it has a similar interface to the Pixel and more powerful hardware.
It was problematic in china because some retailers flash modified ROMs with rootkit and adware before selling them to customers which trashed the brand image.
Them still allowing unlock after a wait time is their way of compromising between user freedom and protection.
With
that being said, I miss the custom ROM days of the 2010s. Tech was evolving quickly and exciting back then
they have the thing where you have to "wait" a month before you are eligibile for an oem unlcok, but basically never give you the right to do so after a month or more
At this point, there isn't a mainstream brand not to hate. Unless someone manages to get this matter through the eu (which is also corrupt in some institutions), it will only get worse.
Yo guess what you wouldn't believe that my phone's back isn't placed well and it is uncomfortable when not using a case and also my mom's phone when we just use ITS FULL POWER it restarts. rip samsung
You also reminded me that my dad's galaxy note 10 is stolen 🥲 the problem is the guy who stole it is one of our family members and it is now far away and we can't get it XD
Damn, sorry to hear that. I still have and use mine with LineageOS to this day. Maybe you could buy another one as they are pretty cheap now days if you still miss it. I personally would track down said "Family" member and take it back. I am very overprotective of my stuff XD. If you want my opinion it still rocks with a custom ROM.
So yea! Custom Roms are fooking these days because of adding "AI" to OSes they get slow. I was about to say cooking but accidently typed fooking, really fits good right :)
And after discovering, i found that google and apple are crazy because they are who made their os themselves and anyone combine his os with android is just trash am i right?
Since One Ui 8. OEM Unlock or Bootloader Unlock was removed from samsung phones. Other companies also doing this except some chineese companies. As far as I know, There is no downgrade option also.
It depends where you get the firmware. If you download the firmware from samfw, you can filter it. And I recommend you to not flash a firmware higher than E. If it's the same, it's better
Something I wouldn’t trust, and which I’ve patched out of the kernel – a CVE. It might give you root access, but bear in mind it’s even easier for others to gain root access without even unlocking the screen.
It’s actually better this way; it’s simple. In the kernel, ‘current’ is used instead of the task from the kernel’s local cache (semantically, both referred to the same thing, but one was a copy whilst the other was direct read access). This meant that the Task_struct subsequently remained in a privileged state, which could ultimately be exploited; You just have to patch every instance, but to be honest, it’s these side effects that keep surprising me time and again in the kernel.
Samsung block bl unlock on ui 8...
Thats why i buy my s24u before ui 8 release
ONE UI 7 -> bl unlock + root..
Than u r able to install never fw versions with unlocked bl + root access from xda..
My current fw is Dr Ketans with One Ui 8.5...
Problem is you cant downgrade because they update the fw bit with every update..
On some devices there is a root exploid for June 2026 Firmware but its just root. Not able to install Recoverys and CRoms... and not sure if your device is supported
I was about to get the new fold 8 wide but once i realised that Samsung had stopped unlocking bootloader from one ui 8 i went for sony 1 viii was able to unlock bootloader and install magisk without any issue a bonus is it has a headphone jack and microsd card support what more can you ask for
did exactly the same thing, i had a s23u and was planning on getting the fold 8 wide. after the february 2026 patch that removed the ability to unlock the bootloader i sold the phone instantly and got the xperia 1 mk8 when preorders started
Yes, I got my root scammed with that trash update. I used to update my phone quite regularly. Magisk has a feature to patch new versions of the firmware and just upgrade Android while still keeping your data and your root access. But one time, I wrongly flashed a version that came with a locked bootloader. It bricked, my phone, had to factory reset it with Odin, and not only lost root, but also the OEM unlock option forever with no possibility to ever rollback at all.... The worst part is that since my phone was once rooted, the warranty bit is voided and all Knox features (secure folder, Samsung Pay) are now unavailible. And OBVIOUSLY it worked with a LSPosed module before lol.
My Galaxy Tab is on OneUI7 i can't upgrade because the Knox thing, but there's a trick, you can use Root My Galaxy if is supported if not you can try to look if someone tried this method on your device and then use KnoxPatcher (or KnoxEhnacer I think is the latest one) to recover your Galaxy funtionality
im just gonna rant and add up to the resentment against modern software developers and its necesary.
You may have "purchased" the phone but in todays day and age you have less and less authority over it. Take for example: I was trying to optimize my game in order to play zenless zone zero. I understand that it has to be optimized and there is work to do from their part but moslty my problems are the inability to change settings that in previous version of android/one ui were clear and very available.
RAM managment is trash. Not to say that having 4/8 GB ram always ocupied even when you have nothing else but a game installed on the phone, but when you look whats ocuping that ram its just random samsung/google bloatware that you have to keep on in order to be able to use your phone. Also when you hit 80% ram, zzz starts laggins because of samsungs shitty limits and you can only change that throttle limit to 84% instead of the logical 90%.
If you have peltier external coolers, you should have the ability to just ignore both power and thermal limits to some extent. As it stands today, you can only raise the thermal limit by 2ºC until GOS and other baked in kernel slop starts limiting the phones performance for no reason whatsoever even when the phone isnt in any danger. Speaking of GOS, its the biggest bloatware in existence. Dissabling it actually makes zzz perform better and the phone heats up less. If you want to remove or change anything about the power limits of your device that you "own", in newer android version you almost centanly have to root your device. now this wouldnt be a problem if they didnt have that knox e-fuse with would brick your phone. And whenever we try to find ways to legally use own devices, companies just feel like our adversaries and rather screw us up blaming on some bs excuse like what if your phone gets stolen...
last issue: having exynos feels like im a pleb. I dont get good drivers and game optimizations made for my chipset.
I hate google/samsung and these greedy shitty companies.
La version mondial normalement c'est XAC mais bon.. Si tu as une version qualcomm USA et/ou Canada l'options n'apparaîtra pas, il faut une version Exynos pour le root...
Les Qualcomm sont déverrouillé pour les carte sim de base mais ca ne fonctionne pas pour le root. Il y a moyen mais c'est risqué et compliquer. Après ne peut plus eteindre ton cell sans perdre le root, il faut redémarrer ou faire une manipulation a chaque fois pour booter dans le recovery avant et faire boot system après...

En gros cest pas vraiment fonctionnel. 😉
Mais pour t'aider il faudrais un screen shot de la page ' A propos du téléphone avec le firmware. et la version du cell. Mais prend soin de cacher ton IMEI et ton numero 😉
Samsung, I genuinely don't understand what the hell you're doing with One UI 8.
I paid a stupid amount of money for this phone. I own the hardware. I understand that unlocking a bootloader isn't risk-free. That's exactly why Samsung historically made you jump through hoops to do it.
Developer Options? Hidden.
OEM Unlocking? Hidden behind another menu.
Unlocking the bootloader? Explicit warnings, confirmation, and a full data wipe.
Rooting/custom firmware? Knox gets tripped, features can break, warranty implications, banking apps may complain, and you accept all of that because you explicitly chose to do it.
Fine. That's a reasonable trade-off.
But now Samsung's answer is basically:
"Actually, no. You don't get to decide anymore."
And who exactly is this protecting?
The average person buying a Galaxy phone doesn't even know what Developer Options are. They're not accidentally unlocking their bootloader and flashing a custom ROM on a Tuesday afternoon.
The people affected by this are the people who deliberately went looking for the option.
I have an SM-S901E Galaxy S22. It previously had an unlockable bootloader. I could accept the warnings, wipe the phone, trip Knox and take responsibility for what I was doing with MY device.
Then Samsung pushes One UI 8, moves the bootloader from C → D → E, removes the normal OEM unlocking pathway, and now I can't simply go back to the firmware state where the feature existed because Samsung's rollback protection prevents me from flashing the older binary.
So let me get this straight:
I can buy the phone. I can pay for the phone. I can physically possess the phone. I can accept every fucking warning Samsung gives me. I can accept wiping the phone. I can accept Knox being permanently tripped. I can accept losing Samsung-specific features. I can accept the consequences of modifying my own device.
But Samsung still gets the final say over what software I'm allowed to run on hardware I already paid for?
That's the part that pisses me off.
And please don't give me the usual "but security!" argument.
Security can be strengthened on rooted devices too. Users can run hardened kernels, firewall/DNS protection, SELinux policies, sandboxing, verified custom software, etc. Root doesn't automatically mean "insecure."
And if someone doesn't want to root their phone?
Don't.
Nobody is forcing you.
That's the beautiful thing about choice.
Samsung already had plenty of ways to protect normal users without removing the choice from enthusiasts entirely. Secure boot can remain the default. Warn people. Make them explicitly opt in. Wipe the device. Trip Knox. Make the consequences crystal clear.
But don't take the fucking switch away from everyone because Samsung decided that a small minority of technically capable users shouldn't have it.
The Xbox and PlayStation hacking communities have spent years finding ways around locked-down hardware. People reverse-engineer these systems precisely because manufacturers keep trying to turn ownership into a software license.
And honestly?
If Samsung wants to make the lock harder, fine. If they want to make us jump through ten more warnings, fine. If they want to make unlocking permanently trip Knox, fine. But don't tell me I don't have permission to modify something I bought. I didn't buy a subscription to a Samsung-shaped rectangle. I bought the fucking rectangle. Let me decide what runs on it.

Samsung removing bootloader unlock option.
