Full wipe before selling - Android Q&A, Help & Troubleshooting

Hello!
I currently have a phone that still has a 1 year warranty, and Im about to sell it.
Before doing so, I wanted to make sure that none of my files, accounts or whatever is reachable by the person buying the phone. How do I go about this, without voiding the warranty?
I heared that factory reset isnt 100% proof in this case?
Thanks!

I think Hard reset is useful for you

You should definitely go for a factory reset and bypass the Google FRP protection.
Look through XDA for thread on how to do it.
If you hard reset it your warranty will be voided .

Is there a need to bypass FRP, if there is an option in the settings to perform the factory reset?
And Hard reset = Wipe with TWRP, for example?

Hard reset is the full reset with TWRP , this will void your warranty.
Factory reset is in your settings. If your device runs Android 8.1 , you'll find this option in System-->Reset Option ( or something like that)

Alright, and what the FRP is for ? Checked up on google, it looks like its a protection that doesnt allow someone randomly factory reset it, right?

Yes , that's a protection prevent someone to factory reset your phone , because he can do it without any password , and back in the day , that's how thiefs reset Android device to resell them .
Now you'll have to bypass it to be able to unlock it .
You can also connect to your phone after factory resetting and logout after unlocking if you aren't able to bypass this protection

Not sure how to bypass it. Cant find a legitimate video on my device. LG G6.
Is it not going to allow me to log in with a different email? Is that how it works?

FRP doesn't work like that , only your previous Google Account can unlock the device , so Google know it's you who has reset your device.

Oh ... that's really bad !
Phone just bought, so you may go back to the store and ask for help or another phone there?
Ok, a hard reset will erase more than only the "unblock" code.
As you do not have any personal data on the phone, and you won't lose anything, you can just try to reset your phone.
Good luck !
Give it a try but Ive read that sometimes it wont work because its not personal data its a security setting.Hope it works but id be doughtful or there wouldnt be any point in putting one in if it was that easy to get rid of.If you know the firmware you have you could root it and format the system.

Take it to a Samsung service center with proof its yours sales bill etc and they reset your handset... Some do charge for this service..
I can't go to service..so a hard reset will delete all?
Or what i can do ?!

Well is your bad at the end of the day...
Look at it this way you may of found said fone it may of been stolen what ever the case may or may not be you can enter a service center with proof of purchase Samsung will unblock and unlock fones as said some change for this service all depends on your location....To me it seem strange you went out and bought your fone but cant get to or ship the fone to Samsung.
As it stands now you cant use that fone so even if you shipped it to Sammy you still be withoiut a phone no matter which way you look at it...
What exactly is a 'deblock code'? The code when unlocking the phone or a network unlock code? Just a curious passer by.
Lol bro,i'm now in another country and i can't go to samsung
Yeah,Unlocking code
So you bought the phone and left the country in the same day
Sounds like you robbed a banked.Are you talking about the device pin code or another blocking code like go locker?
Devince...
Yesterday i bought(at 12:00 Germany) and today i arrived in my country..
Yes,pin unlocker phone no go locker
Why don't you just root it and use one of the many apps that are available to unlock it? That's what I did and it worked just fine. If you do proceed to do it, make sure you back up your EFS!

If its a device PIN Lock then a Factory Reset wont work because a Factory Reset wipes personal data and a Device Pin Lock is a security setting.You do however have a few options,
1.Find your receipt and find a Service Centre in your country and HOPE (and probably pay) they will unlock it as Samsung are global.
2.Root your device with a CF-Root kernel and format it completely in "mounts and Storage".This formats System,Data and Cache but you need to know what firmware it has to use the correct kernel and not brick your phone.(differing reports of this working but mostly it does).
3.Root and use and app from the market as posted from the user prior to my post but once again the problem of the correct kernel pops-up.
You main disadvantage is that its a security thing.They are put there to piss people off.Only its a bugger when its the owner

But,who i can do the 2 ? Cf root?
I'm noob...
You need to know the Firmware it has to match the kernel.The rest I can guide you BUT if you dont not know the Firmware or kernel you WILL BRICK your phone.

Help!!! locked phone!

My wife has the Tmo LG V10 secured with google but she forgot the password to her account. So I decided to factory reset the phone by hitting the button combination and entering recovery. After the phone booted up it still asking for the google account password. And there's no way I can unlock the phone. Is there anyway to do this? By unlocking bootloader and installing a fresh rom? I thought on rooting it but I have to enable developer mode and I can't access it. Any ideas??

Can she get on another device and reset her Google password?
Log into Google and select forgot password and reset.

If you are unable to just reset the password and wait the 72 hours try this. http://forum.gsmhosting.com/vbb/f779/lg-v10-factory-reset-protection-frp-2064805/ this work around wworked for me a couple days ago. Or if it doesn't I guess you ccould always pay mrcertkings extortion of 20 dollars to use the tot file to fix. I'm sure he's already pmed you offering to do it for 20 dollars like he did me.

Is there another way to bypass this issue?
All help is more than welcome,
Thanks

Reset via recovery?

[For newbie] FRP and Phone lock / unlocked explanation

Hi people!
I know, I'm completely newbie in this.
But I'm getting in trouble and confused about it.
The question is simple:
What's means FRP lock / unlocked and Phone lock / unlocked?
And what's the difference between them?
FRP means Factory Reset Protection. If locked your phone will be protected of unauthorized factory​ resets. If a stranger tries to reset your phone, the phone will ask for your Google password on startup.
So if you unlock FRP you will lose that protection but this is required too unlock your bootloader (that's what you called phone locked/unlocked).
Phone locked (bootloader locked) means that you cannot make any changes too the partitions of your phone for example the recovery. So you are required to unlock your phone to install custom recoveries and ROMs like TWRP or RR etc.
Hope I could help you clear some things up.
If you're planning to sell your Android phone, make sure to remove your Google account from it first or else the next owner wouldn't be able to use it.

actory Reset Protection (FRP) is a security method that was designed to make sure someone can't just wipe and factory reset your phone if you've lost it or it was stolen. Starting with Android Lollipop, FRP is "standard" in vanilla Android, and most companies making our phones have implemented it in their own models.Mar 29, 2016

Hi everybody,
My question is going to sound stupid, but now that I've got the unlock code for the bootloader, how do I unlock the FRP?
It is to this part that I am lost.
Sorry but I'm not very young anymore and not healthy. I had a big car accident and am much more on my phone and my computer

You need have enabled OEM unlock in Developer options for unlock FRP

Hi,
OK so I activate the OEM to unlock the FRP.
And for unlocking the Bootloader I can use Huawei Multi Tools?
Should I delete my Google Account or Huawei before doing these manipulations?
I do not have fingerprint or pattern lock.
Thanks in advance for your answers.
This video is for the Honor 8, but the same steps are used to unlock the bootloader on the Honor 9.

I unlocked the bootloader. Done on the instructions of the website:https://emui.huawei.com/en/plugin/unlock/step. After unlocking bootloader on my phone fastboot appeared the inscription "PHONE Unlock" and "Unlock FPR". On my device sprosili settings. After that, I re-entered entered the Google account, but the phone then began to hang periodically. I went into developer mode, done a factory reset there. And decided to turn back. Went to fastboot, blocked Downloader. Phone rebooted, then on the screen appeared the inscription: "Relock PHONE" and "FPR Lock". Out of fastboot, there was a black window where it says to restore the system through recovery in the air, but when I try to do fails. Help me, please!

Tab S6: Factory Reset with Stock ROM and still getting "protected by Knox Cloud Service"

Recently purchased a used Galaxy Tab S6. I was warned it had a warning about the bootloader being unlocked. No big deal. The seller couldn't remember his Samsung account credentials so we couldn't factory reset at time of purchase via Settings. No big deal. I went into Download Mode and relocked the bootloader. I went into Recovery Mode and Factory Reset.
Then I ran into "This tablet is protected by Know Cloud Service. To continue setup, connect to a wi-fi or mobile network." I've done that (since I can't skip the step) and get the dreaded "Can't create work profile" error and that's as far as the set up will go.
So I used Odin to flash the latest stock ROM and factory reset again and wiped the cache and I'm still having that problem.
In download mode, I've confirmed that Knox has been tripped.
I've googled like mad and I'm not finding a solution. Can anyone help me out? I'd prefer to stay on Stock ROM so there are no hardware issues (particularly with the SPen) as I'm planning to use this device extensively for note-taking (with OneNote). However, I'm open to custom ROM if that's my best/easiest/simplest route.
Thanks in advance!
If you're able, unlock the bootloader again. When you flashed with Odin, did you use the CSC or HOME_CSC file?

I used CSC. As I understand it, that is the "deeper" reset option.

Correct, that wipes user data.
Unlock the bootloader again, which will wipe the device (again), and see if it's removed the FRP. If not, you should be able to flash TWRP, from which you should be able to flash this to disable the FRP.
I can't access the developer options because I can't get through the setup wizard. So I can't flip the OEM Unlocking so the download mode doesn't give me the option to unlock. I can connect to ADB via the Recovery Mode but Fastboot doesn't see it so I can't do "oem unlock." Are there any other methods to unlock it? My friend Google hasn't found any yet.
Seller was able to login to both his Google and Samsung accounts and remove the device from them. That got me through the 100% Know Enrollment Service before it hung up in the "update" portion again. He was also able to send a message to the tablet from the Samsung account to try and release it further but, of course, since I've wiped it, that message can't get through.
I'm getting desperate. I might have bought a paperweight! Any once else have a suggestion?
Checked with the seller. He bought it from Kijiji as well from the original owner. It's always been a personal device, never an institutional one.
Last night's searching of the internet determined that the device is in "prenormal" status so I'm just going to wait 7 days and reboot. That might be sufficient. Nothing to lose at this point.
