Hi.
Before my question I'll write about my experience because I am sure it will help many many people.
As many of you, I always ROOT my smartphones.
Nowadays, the new phones, they come with this new technology to avoid root and other things called " OEM Lock " under the Developer's Options.
Following every step provided in the root guide for you phone, the new step to enable OEM Unlock under Developer Options
is a must!
The only thing that they don't say is that you MUST leave OEM Unlock ALWAYS ENABLED during and AFTER the root, and not only during the root
process.
Not knowing that, what did I do? Right After rooting my Samsung Note 5 I disabled the OEM Unlock. When I restarted the smartphone, it got into something called FAP Protection Black Screen where you are not able to leave not even if you try to root the phone again with the img file!
If you get in the FAP Protection Screen, like I did, despair will take over, I promise! And Google will not help you!
Is there a solution?
I found one, but not in any Google Page.
You need to download the firware img file for your phone, exactly same model,
in my case it was SM-N920G (Samsung Note 5), and for your specific country. Luckily for my phone it was not so hard to find, just hard to download (1,7GB with average 15 kB/s speed!). You will find different versions, some related to a Phone Company Operator that your country has, other related to no operator at all (sure I chose that).
After you get the firware file, just use Odin with that file to flash the phone, just like how you did to root the phone, but now, instead of using the root img file with Odin Software, you'll use the firmware file. That will not only solve the problem and give you access to your phone again, but in my case the Operator Flag disappeared and the data and apps installed miraculously were intact! I was pretty sure I was supposed to lose everything, but that didn't happen!
I'm sure what I wrote above will help many desperate people out there!
Now, my main question here:
You can never disable OEM Unlock in your life, with a rooted phone, period! So, it's really dangerous to leave the developer options enabled, allowing anyone that uses the phone to change it, even if by accident. In my case, as another example, besides rooting my phone, I rooted my father's phone too (because it was previously mine). I'd like to avoid by any means that by any chance me, or my father, disable to the OEM Unlock.
So, my question:
If I disable the Developer Option in order to "hide" it, will the changes that I did inside it remain working perfectly? I'm afraid that if I disable the developer options, somehow, it might take every option inside it back to the "default", just like it was before I enabled the developer Options, meaning in this case, OEM Unlock would get DISABLED again!
Is it safe to disable the Developer Options when OEM Unlock is Enable and MUST Remain like that?
Thank you.
Lost a night of sleep for the same problem with a Samsung S8.
This should be added to *every* mod guide.
In my case was worse too...if you root the phone and wipe data, when you open first time developer option you'll find "OEM Unlock" disabled (but I assume it's enabled at bootloader level). So when I check / uncheck it I doom my phone to lock on next restart...
how to get to boot menu on htc u12 plus, smallest width setting got adjusted wrong in developer options and power got cycled, all I can see on lock screen are 1,2 and 3 cant unlock, any ideas?
With the pattern to the screen lock forgotten, I desperately need to gain access to my Alcatel Raven.
I need to recover photos, sms/mms messages, contacts, saved app login info (that didnt have permission to sync to my google account) and music files.
I have many obstacles to overcome however...
no root access, only stock recovery, bootloader locked, developer tools not yet unlocked and debugging not enabled.
I do have the credentials for my google account that it's signed into, but because it is running Nougat 7.1.1, I get no forgot password option after 5 failed attempts and android device manager is useless for unlocking the device. Dr Fone and other 3rd party unlocking software either needs debugging enabled or is not compatible with my device model. I do have wifi access and bluetooth, but the phone has no carrier service as far as making and recieving calls and/or sms/mms. It does have an sd card slot but as previously stated it only has stock recovery mode and the bootloader is locked. I do have access to adb and cygwin on my laptop and I am confident that with debugging enabled I can handle the rest. The part I cannot figure out is how to enable debugging on this device with the screen (pattern) locked and without using an otg cable (which I have no access to unless I order one) and I'm not even sure if an otg cable would work with this particular device model or not.
Can anyone help me!?!?!?
Hello, thanks for reading my thread. This is probably my first thread in xdadevelopers. So, I will describe my problem with FRP lock.
I just buy a two-handed phone from some people and yes, I forgot to check properly that they erase their Google Account to prevent FRP. I struggle to unlock this FRP lock. TalkBack bypass is not working since it is 7.2.0 version and since this phone didn't enable USB debugging. I can't run any command within ADB. I tried multiple ways to bypass FRP like SMS, Trying to USB debugging with *#*#2846579#*#* code, Tring to flash the ROM but not working at all. Can someone recommend me what to do? I really need help right now.
Thanks,
Best Regards.
there no way to remove frp for this phone except the test point method.

I have a problem with my Xiaomi Mi 9 Lite. Some time ago I've setup a screen lock with password I can't remember. How can I disable it? USB debugging is off, bootloader is locked, no custom rom/recovery is installed. What I want to achieve is to not lose any data so in this case is there any possibility to copy the data from the device?
Thank you for any support.
Contact to your service provider or product manufacturer provide them with the information they ask for, and see if they can help you. They are the only ones who will assist you in these matters.

The door to any Android device is ADB ( read: Android Debug Bridge ) enabled ( Settings -> Developer options -> USB debugging ). This is the first setting every Android user should make when he starts using an Android device. Doing so then most problems can get solved by user itself.
I was wondering about this Network unlock (sim unlock) method actually worked or ever worked?
OnePlus Nord | N10 | N100 [TMO/MPCS] Network Unlock & Enable OEM Unlocking (April 19th, 2021)
1.) ADB access must be enabled -Tap build number 7 times until Developer Options are enabled 2.) Enable USB Debugging -For PC-less enable Wireless Debugging Optional if PC-less 3.) Go to Play Store or F-Droid and download Shizuku 4.) Tap...

Doesn't actually work right? I mean for a phone that is not yet reached Metro's 180 days after initial activation rule, or TMO's full year of activation rule?
Someone said try the "chinc in the armor thread" but is just a method to bootloader unlock method to bypass having to network unlock first . Does not actually network (sim) unlock.
Am I getting this right? No way to sim unlock an N10 outside of waiting 180 days, or paying a 3rd party service right?
Thanks.
