Enable usb debugging on locked phone - Xiaomi Mi 9 Questions & Answers

Hi there I have a phone with a forgotten pin code so I was trying to use some software but every software needs the phone to have the USB debugging enabled... so I was wondering how can I enable it from fastboot mode or are there other ways to do that?

USB debugging is not enabled through Fastboot but from Settings, Additional Settings, Developer options.
Google for gow-to 'become developer' and to unleash Developer options
However, if you cannot unlock your phone, you could not open Setting, My phone, etc, to 'become developer'
Btw, I really don't understand how a user can change a pin and forgot it

Nevertheless, legitimate user (knowing his email and password he registered at Google) can still login from PC to the Google account and use the methods how to change pin/unlock the phone

[Q] Remove pattern lock

hi guys can someone please assist me and I will donate $15 via paypal to the account of the person who can. I need to unlock my Samsung galaxy s5 at & t version phone that has a pattern lock (but also a bootloader lock so I cannot reset the phone). Moreover I do not have a google account registered to my phone so I cannot request a different pattern to unlock the phone. Also usb debugging mode is disable. How can I get back into my phone?
I think you can find a video about that on youtube. We don't need to be giving that information here for the bad guys to read, and bypass other people's lockscreens.

Help! Note5 is no longer recognizing my fingerprint

So, this sounds simple; but I guarantee you it is not.
I just got my Note5 about 2 weeks ago; and despite some missing key features, I really like it. Until today.
Carrier: Sprint (who apparently doesn't have 24/7 customer service)
My fingers were a little dirty (which they have been before) and my scanner wouldn't unlock the phone. Cleaned them and now it's already locked and seems to not really check the prints anymore?
First attempted fix: backup password, I know I set it up...but it doesn't work. None of the passwords I might use will work.
Second attempted fix: Google signin, I have a free google apps account and apparently using my whole email address as username doesn't work on this; also tried just using the plain username just in case. I know the password is correct. I'm the domain administrator.
Third attempted fix: Android device manager, tried setting a new password on the lock screen and was greeted by the infuriating message "Since google has verified that your screen is already locked, the password you set won't be needed"
Fourth attempted fix: chat with samsung support, which was utterly useless. Although I did find out that samsung has their own unlock utility...except that it has to be setup beforehand.
Fifth attempted fix: bang head on cement...hasn't shown any signs of working yet. Although I feel less frustrated.......and less conscious.
Theories: free version of Google Apps, sucks (the apps themselves are great)...I've had tons of trouble getting signed into certain google features over the years. Also I have no option for a support PIN to use to contact google support.
I think that my latest OTA update may have somehow changed or reset my backup password.
The last theory is whomever changed Android device manager to not reset lockscreen passwords whenever you want to...basically made that tool half as useful as it should be and completely useless to me.
Anyone have any other ideas, that don't involve a full wipe?
I was finally able to gain access to my phone. I had to disable two-step verification in order to sign into my google apps account from the lock screen.
I am having the same issues and tried ALL of the fixes you tried except I didn't get the notification to login with google. When does that happen?
I had the problem, too. I ended up having to factory reset. REALLY irritated by this.

Is Samsung 's Find My Mobile available on the Verizon Note 9?

Hi,
I setup my Samsung Account and it says under services that I have Find My Mobile.
I go to the find my mobile website and login and it has my 2 other Galaxy Tab Tablets listed but not my phone.
I look at setup tutorials and the say goto lock screen and security but my settings has a "Lockscreen" and a "Biometrics and Security" sub menu.
Under the Biometrics and Security there is a Find My Device which is set to on and when I tap that I get a page that has the slider for on and below it it says ways to locate device:
options are:
Find my Device
get it on google play
Web
Visit android.com/finf
Google Search "find my Device"
What is going on?
I am a little freaked out.
As I understand it if you use lock like pattern lock that through Samsung's Find My Mobile site you can reset the login if you run into trouble. I almost did run into trouble right after I finish setting the Note 9 up after 3 hours, I restarted it when I put in my Memory Card and my pattern was not working. Got to where I had 3 tries left. I turned it off reset the sim card and the memory card in the holder and it worked. There have been other times where it did not recognize the pattern once or twice but did finally. Not sure if with the curved screen my hand was touching the screen and that caused a problem or what but. I need the phone locked and I need Samsung's Find My Mobile with it's unlocking feature for piece of mind.
One article on seting it up a comment said they were told it was not available on the Verizon version. True not true?
What am I doing wrong to set it up.
I had lookout installed but removed that.
I also have Teamviewer Host and the Samsung Host Plugin for Teamviewer installed is that interfering?
I need a fallnback way to unlock if the initial one fails.
Thank You.

How do you get around it if you bought a refurbished android moto XT1650-02 on FB and they didn't do what they should have done here in this post?

Have a look at my posts on this subject.
Currently I'm looking into whether I can side load some code via a FAT32 formatted SD card, and if possible, I need to locate where the flag is stored which sets this FRP. Now this could be stored on a rom chip of sorts and at this stage I dont want to break open the device to desolder chips, so this blog could be useful at giving clues into what needs to be looked at. Although the device is a Blink Mini camera, the technique can be applied on other devices, like smart phones.
Blink Mini RE, Part 3 -- Staring into the eye of the binary
If we stare at a binary for long enough, we will intimidate it into giving us its little secrets
astrid.tech
Ideally, I'd have a working device, dump the rom contents, then trigger the FRP and then dump the roms again to compare whats been changed, which would hilight areas for further investigation and maybe even the bit flag in question.
The other area of interest currently is Wireshark with the USB packet sniffer. Lenovo's/Motorola's Rescue and Smart Assist program aka LRMA can interrogate the device via a USB cable and detect the firmware. LRMA also suggests enabling the Developer mode/USB debugging which is enabled by clicking the build number seven times in the Google Android settings. So the question is can LRMA detect the FRP has been set? If it can, Ghidra https://ghidra-sre.org/ can be used to detect the FRP bit flag. I say bit Flag, it could be multiple bit flags in a variety of locations. Never under estimate your enemy.
I've used the Emergency Contact select a photo trick, to gain access to all apps, where I've gone straight for the Settings and Build number, tapped it 7 times as per LRMA's instructions but its not unhidden the developer mode and USB debugging options. This could be disabled once FRP is triggered, but its why I say it could be more than one bit flag which is set. Like you see with UEFI bios on some pc motherboards, there could actually be a two or more locations which could be used.
Like I said earlier, having a working device, dumping roms and then triggering FRP would be ideal, but when you dont have any money, it forces you to use your brain as you can't just step out and buy a new device mirrored in every way.
At this stage I dont know if this FRP flag can be undone. It might be like these RaspberryPi One Time Programmable switches as seen here, but I have been able to toggle some of those as well! https://github.com/raspberrypi/docu...asciidoc/computers/raspberry-pi/otp-bits.adoc
I've so far been unsuccessful in finding out if there is an equivalent of vcgencmd otp_dump for Android phones as this could be another way I might be able to find the FRP flag without having to dump the roms.
This is all new to me so I might be looking in the wrong area's as I'm just an unqualified out of work for decades boring old penniless windows programmer so I'm learning as I go along. But you might find what I've put is useful if you fancy a Thanksgiving, Xmas & New Year challenge for a change.

Question Help! My friend's Galaxy S21 Ultra is locked by scammer.

Hi everyone, I'm trying to help out a friend whose phone is now locked by a scammer.
1. My friend has online store at Shop*e (One of the largest E-Commerce apps in South East Asia). The scammer called, claiming they're from Shop*e, and described some of the data of my friend's store in Shop*e, hence the scammer managed to convince my friend that it's from Shop*e.
2. Instead of personal Gmail account, my friend has a separate Gmail for this online store business, so his Galaxy S21 Ultra is logged into that Gmail for the main google account of his phone.
3. The scammer asked for his Google's Security Code which contains Code 1 & Code 2. (Settings -> Google -> Manage your Google Account -> Security (tab) -> Security Code (under 'Signing in to Google).
4. My friend gave out the security codes, now his Galaxy S21 Ultra is locked, and it requires PIN to unlock the phone, and only the hacker knows that PIN. There's no alternative unlock method offered.
5. My friend also checked that his compromised Google account is now logged in to the scammer's phone, Vivo.
Please help, what should I suggest my friend to do beside factory resetting his phone? How can he unlock his phone?
Thank you.
A factory reset won't help; Google FRP is active.
Google it for solutions. Their other problem is their lost Google account. Good luck with that.
Any other accounts/passwords they better have already reset
No saving dumb bunnies... no offense but that is beyond completely inept. So much so I'm hesitant to believe it.

Thanks for the answer. I also couldn't believe it, very dumb mistake indeed.
When Google FRP is on, we also can't factory reset from Android Bootloader interface? @blackhawk

I think your totally locked out except for round about procedures.
Never been there... that's going to be fun.
Do you have access to google account?
What's the value for the scammer stealing the account? Maybe he's hoping for information stored in Google Cloud which can be exploited? Getting some paid apps for free in the Google Store? If the victim has payment options which auto populate during an online purchase, these methods should be revoked. What other factors would motivate the theft?

Motivation doesn't really matter in this context; some people simply enjoy harming others.
OP, I think your buddy's best recourse at this point is to factory reset the device, then recover his Google account if possible, and change all passwords that may have been on the device. He should also monitor his bank accounts for fraudulent activity.
Edit: Is the bootloader unlocked?
An ounce of prevention is worth a pound, or sometimes a ton of cure. NEVER, EVER give out any security information, ESPECIALLY to someone you don't know on the Internet.

FRP is active so without the Google account he'll be locked out after factory reset...
No easy fix.
Will Google help? Don't count on it.

Not even from recovery mode or bootloader? Edit: apparently not, FRP lock might as well be a hardware lock
Might be able to bypass if bootloader is unlocked

Depends, proving identity can be difficult, and it's true the Big G's customer service is not known for their efficiency or expediency...
If it's an unlocked phone this allegedly should work.
Every other solution is complicated and likely against forum rules to post.
Using the Developer Option:​Go to the settings Menu > then About Device > tap on the “Build Number” more than 5 times > go back to settings menu > Now tap on the Developer option > check to Enable OEM Unlock > Done! Now you can reset your phone without facing the FRP lock
My Note 10+'s are unlocked so this solution helps me. I loathe FRP.
