Refurbished device with unlocked bootloader, safe ? help please - General Questions and Answers

Hello,
I've just bought a refurbished device on amazon, but when i started it, it shows me the screen with "The bootloader is unlocked and software integrity cannot be guaranteed"

"lightbox_next": "Next",

}
The warranty is gone, but it's ok.
I have relock the device with fastboot, the name of the rom seems legit.
My question : is there still any security risk ?
Thanks

Unless it was specifically advertised as unlocked and you specifically bought it for that reason, I'd reset the phone with an MSM tool or similar.
Maybe I'm just OCD. I factory reset every electronic device I buy before setting it up.

I can't find a copy of the device reset tool on the forums or the manufacturer website.
I would research the issue further on the following sites:
How to Reset the Motorola one vision
Motorola One Vision Questions and Answers (XDA)

Having a device's bootloader locked simply means that device only will boot into / run Stock ROM: This has nothing to do with whether Android is safe or not.

thanks, yes i have relock the device myself.
But is it sure that it’s now using the original stock rom ? And not a hacked one ?

YES, because original Stock ROM is signed by manufacturer: the bootloader verifies this signature.

Thanks a lot.

New phone - HELP - Custom Binary blocked by FRP Lock.

Hello guys
I just bought (2 hours ago) a new samsung s7. I got a receipt from the guy from who i purchased from, and he told me that the phone was "operator unlocked" by a friend of his.
Now I got the phone, he gave me the proof of payment (that he purchased and didn't steal, I hope ...).
Before I started to set up everything, I did a factory reset.
I booted it up, entered my gmail account, all other accounts, facebook etc....
All good. Then I decided to do a quick restart, and now it won't boot, it says "Custom Binary blocked by FRP Lock" (I attached a picture also).

}
Now what can I do? I contacted him and he told me that tomorrow he will help fix things.
My question is this:
a) This message appears because I entered a google account different from the original one?
b) This message appears because they unlocked the phone
What message do you get if a phone is stolen? Is is the same? Because if this is simply a custom build installed, then I can revert back to original OEM build (I am in the same network as the phone was purchase from, so I don't care about unblocking).
So do you guys thing it's b from above? And maybe if I do http://forum.xda-developers.com/galaxy-s7/help/frp-boot-fix-sm-g930f-t3350149 it will be OK?
Thanks!

This message appears because they rooted the phone and forgot about the OEM lock
What your seeing is exactly that thread linked so yes that will work just fine.
shamed to admit it but I did the same thing

To unlock operator a phone, you need to root it, right?

Hi Sodevrom,
To solve your problem, you have to flash via Odin Official Samsung Firmware.

Model:ZC520TL this the get var all command from fastboot mode

a dump of the var for reference i noticed boot is locked and not the same as others out there
The Zenfone 3 Max uses a Mediatek processor, which makes the chances of it getting any custom ROMs very slim.
still waiting for the bootloader unlock
i m still waiting for Asus to send the unlock bootloader for this device probably will wait forever or i will just break it trying to do it myself
i hate the fact i cant remove all the zen talk and other bloat ware in there need to be very carefull on my next phone for sure

I'm on Global v9.5.4 with unlocked bootloader. Not showing an available update. Is that due to the bootloader being unlocked?

There you go
Note that you don't need twrp or anything to install this on top of the regular global rom -- just put the zip on the phone and select it with system update.
I appear to be having a problem with this update. Its just hanging at the Mix Screen (powered by Android). I patched from inside the updater app.
Edit: I had to wipe and start again with new update. it wouldnt flash back to 9.5.18. Only thing that worked was a fresh install of 9.5.19.
It need be flash from global rom , if you flash from other version?

SUCCESS! [BOOTLOADER UNLOCK] Nokia C2 Tava TA-1218.

[BOOTLOADER UNLOCK] Nokia C2 Tava TA-1218.
Requirements:
Windows PC
USB Cable
MTK Drivers and LIB USB
I was actually approached by a person from XDA named @Soadeathdealer who gave me remote access
to unlock his phone's bootloader. I'm thankful that he let me use his device for this experiment.
This phone bootloader was successfully unlocked using Unlock Tool which is paid software
but you should be able to unlock it using mtk client as well.
Please PM me if you need any help.

Hi!
I downloaded Unlock Tool but it needs to be activated (paid for). How did you pay for it? I clicked the "activate" button and it went to an obscure reseller page with no info on how to pay.
Thanks in advance!

What do you need from me? The bootloader codes? I found it odd they only wanted the IMEI number.
I already tried 'fastboot oem unlock' that did not work. Just let me know what you need! Thanks!

No you just need to setup MTK drivers and I'll do the rest.
But I'm away from my computer today. I would be able to help you tomorrow.

Question Is it possible to fps bypass by flashing combination firmware on s21+5g? Snapdragon a.13

I have a snapdragon s21+ 5g Android 13. Is it possible to frp bypass with combo firmware?
If you find a working one, these days it is hard to find combination firmware!
Also, there are some online services that can help, I can recommend the Progeeksblog FRP Unlock service, but unfortunately it is not free. They also have some free guides on how to workaround it.
Disclaimer: The purpose of this guidance is only for educational purposes. I by no means encourage the illegal use or unlocking of stolen smartphones.

If you are still looking to unlock it, please comment down here. I will only help you if you are the genuine owner of the device.
Yes, I am the genuine owner. I have been using my pixel. I recently decided to start using my s21+ again and reset it to get a fresh start on the phone and I have completely forgotten what Google account I used with that phone , it's been over a year. I can provide a copy of it's blacklist status if you need to see it. It is clean.
