Is there a way how to set a password or PIN lock for the bootloader or at least the recovery? There's been a lot of break ins in my area lately and when someone steals my phone, I wanna make sure that it will be rendered completely useless (Including IMEI blacklist) and non-recoverable.Is there a way how can be bootloader & recovery locked so a thief can't access the recovery without a password or a PIN lock and thus not able to reset the phone to factory settings?
So far, any anti-theft software I've seen doesn't have this ability and can be easily removed by factory data reset

I believe, but not sure, that TWRP has a PIN code system
You should try Cerberus or avast!, with root they can lock into the system which means the thief has to reflash an FTF file
EDIT
Nope, TWRP doesn't have PIN protection. If you want to secure your phone, some tips:
1. Make sure the on/off menu cannot be opened when the phone is locked.
2. Make sure your data is always on
3. Use CyanogenMod Account / Cerberus / avast! AntiTheft
x. If you phone gets stolen, use one of the above programs to lock and wipe your device.
Hi @ all,
i have a problem i sold the XT1541. Had used it before with my google account for testing purposes. Before i sold it i forgot do DELETE the account from the phone and just did a factory reset via recovery.
The customer now cannot log in with his account. Is there anything i can do to help him - would not like to give him my account infos. Any input would be reakky helpful.
I did not know about this new feature....
simple (easy): Just go to your customer and log in for him and delete your account
harder (risky): flash the stock firmware
Try factory reset via recovery
Well the customer is 500km away. So its not an Option to visit him. How could a second factory reset via recovery help in this case? The device is still bootloader locked. Can he install the stock Rom without loosing the motorola warranty? I could assist him via teamviewer. But he does not want to loose the full warranty.

Delete all your info off your Google account(credit cards, Google+, etc) and give him the password and Google email so he can bypass then have him delete it in settings.
Or return the phone and give him his money back.
To my knowledge you can install stock firmware without unlocking your bootloader, also in my post above a i meant via the bootloader menu.
I hope another member can confim whether you can factory reset via the bootloader menu
Yup! Stock recovery has this feature!
I unluckly discovered that with the may security update, both unlocking and locking the bootloader will result in a complete wipe of all user data.
Is this intended? Will this be the standard for all the next updates? It's really a shame that unlocking ther bootloader is now a relatively pricey and hard thing to do.
Or did I just do something wrong? Lost data... twice in a day
What about GCam and root if the bootloader can't be altered without clearing all user data? Does this mean I'll have to dump my data every time I update my system (and so root again)?
Hope someone knows better than me :crying:

Yes, from now it's "normal"
On all devices you lose all data for locking/unlocking BL, our Mi A1 was lucky.
Its upgrading security
Wiping FRP was a piece of cake
Hello,
a friend of mine gave me his U11+ because he had a problem with it. After a factory reset he can start the phone and log in to wifi, but after that, the phone always asks for the last verify PIN
He told me he never had one.
At first i tried a factory reset and a cache wipe with no effect. Then i flashed a ruu with the SD method, but the Phone keeps asking for the verify PIN.
The Phone has S-On, is not rooted and the bootloader is looked.
Does anybody know, how to fix this?
Thanks!
Chris
Ist it maybe possible, to delect or chrash the current Firmware and then installing the ruu again? I don't know, where the information about the verify Pin is saved.
Please help me

i've read a blog post somewhere which talks of the possibility to lock a sumsung download mode, how can this be done or undone?

Can you provide more details?
The bootloader lock prevents flashing and booting of unsigned images. With a locked bootloader, download mode does not accept custom software; all software packages must be OEM signed.
An unlocked bootloader (with Knox Guard disabled) will allow flashing custom firmware, such as TWRP recovery.
So, in that sort of sense, I suppose the bootloader lock does control what download mode will accept via Odin.

im on the sumsung galaxy a032F, there is no oem unlock in developer options so i guess i cannot unlock the bootloader, and when i try to flash a custom firmware via odin i get an error mdm mode can't download odin. so after reading the blog post i was wondering, could the download mode be locked

Ah, ok. That makes a little more sense.
The bootloader has to be unlocked in order to flash custom firmware.
The process works like this:
Turn on OEM Unlocking in Developer Options (allows bootloader to be unlocked)
Boot device into unlock mode - starting with device off, hold both Volume buttons and plug in USB cable)
Follow device instructions to unlock (will wipe data)
Boot into system, allow system to connect to Internet to disable Knox Guard
Reboot into download mode, use Odin to flash TWRP
Use TWRP to flash custom ROM
So, if OEM Unlocking is not available, you can't do any of this, because that is the first step.
Unless you have factory restarted your device within the last week, no oem unlock means no custom firmware. You have the snapdragon variant, right?

thanks for the answer, but i was wondering is there a way in which the oem unlock option can be hidden and unhidden or some way in which you can be prevented from unlocking the bootloader, because even the wipe data/factory reset is disabled, i came across this kind of devices and i was just curious is this entailed in android development or what material can you recommend if i want to know more about this

Bootloader lock doesn't prevent a factory reset. The screen you showed is recovery mode, not download mode. That's really strange, I've never seen factory reset hidden before

I think this is the clue. You have a organization managed device with an MDM lock (Mobile Device Management). MDM is used by enterprise IT departments to manage devices and can prevent bootloader unlocking as well as factory reset.
Let me guess, you bought this device used?

I think your only option is to find out which company the phone belonged to before. If they removed it from their fleet, they can probably remove the MDM lock. This is actually pretty common - enterprise managed devices will be "retired" from fleet service and sold without being properly decommissioned - they're wiped, but the IT department doesn't remove the MDM lock.
They might or might not unlock it for you, but it doesn't hurt to ask.

so technically i can't find a way around it myself, i just have to request the company
There is no way I know to bypass it.
There are lots of videos online if you Google “ bypass mdm lock android “

MDM locks typically can't be removed by the end user. That's the whole point - to prevent employees from using devices inappropriately and removing them from enterprise management via factory reset
Kolay gelsin hocalarım telefon kendi kendine Samsung yazısında kaldı revovery kullanamıyor bende Odin ile stok rom attı kilit açmadan
Şuan telefon indir sadece tek giriyor başka hiçbir şey açılmıyor OEM kilit ve frp kapalı
Take it easy, my teachers, the phone is stuck in the Samsung text itself, cannot use revovery, I have a stock rom with Odin, without unlocking it Now the phone is downloading only one entry nothing else does not open OEM lock and frp is off
