Lost or Stolen Poco F1 with unlocked bootloader? - Xiaomi Poco F1 Questions & Answers

Hello everybody.
my question is a little bit noobish, is losing a phone with locked bootloader have any security benefits?
like if it's lost or stolen can the thief access my data ?? can he use the phone after formatting it ??
i really need to know it, and my English is not very good as i tried to search for any updated topic about this matter and i couldn't find such thing

On locked bootloader, he can't access your data as your storage is encrypted and any attempt to unlock the bootloader will wipe the storage out. Even if he does some kind of a factory reset, he will still come to the point where he needs a password to unlock the phone after a reset. So no, he can't really use the phone if the bootloader is locked.

With locked bootloader, the thief will not be able to use the phone at all if you have it in secure lock screen.
With unlocked bootloader if you are encrypted (not flashing fde) he will be able to use the phone but will never have access to your data.
With unlocked bootloader and unencrypted (by flashing fde) he will be able to use the phone AND have access to your data.

Thanks guys very helpful, I needed to know the risks... Many thanks [emoji4]

Eventually you can unlock the phone, without using FDE, and backup/flash/restore with an USB-OTG cable and a USB drive, so your data will be encrypted but you still can "play" with your phone. That's what I did.

Unlocked bootlader with encryption turned on

I've got a Motorola Atrix 4G on 2.3.6, with 4.5.141
I used this method to unlock my Atrix's bootloader: http://forum.xda-developers.com/showthread.php?t=1182871.
At first all my files appeared as corrupted and could not be viewed, but they were all there.
Then remembered I had data encryption turned on, now I can't access the backup I made with mybackup app, nor access the internal storage's photos and documents.
I've read somewhere that the Razr would decrypt the data with the PIN, I've set the same passwords, tried enabling and disabling the encryption but had no luck...
I was wondering if there was a way to make the phone decrypt it and restore my backup...
I've found little to no info on this, but I can't be the only one with this problem...
were screwed ( it says unlocked but it actually isnt, i made a thread about this before. After i got my atrix warrantied , they gave me a newer model(piece of ****, excuse my language)that isnt actually unlockable. Does yours have 2 visible lights at the bottom of ur screen in daylight, and does ur screen keep popping up ? mabye im just unlucky
?

Mine says unlocked, the problem is I made a backup that got encrypted by the system and I fear the key used to encrypt it got deleted, maybe if I search with a data recovery program(I would need the name of the key) so I can replace it and let the system decrypt it like before...
Mine does not have any visible lights at the bottom of the screen, don't think the atrix got them.
Maybe I'll buy an HTC One X and drop this...But I want my data back!

Factory reset should do it. That's the only way I know to remove encryption.

Isn't factory reset supposed to delete everything?
I want to decrypt my data, so I can see my photos, documents and backup, does factory reset enables the normal usage of original files?
I need to keep my data intact, so deleting it won't help me get it back.
I've found an interesting information on encryption on Motorla Razr: forums.motorola.com/posts/b027ce4327
But unfortunately it is bad news, and something I hope is not the case in the Atrix...
I've used a data recovery program: Testdisk
And found a lot of files with criptokey extension...If the encryption is based on a key per file, I'll just drop the phone in boiling water, or sell it...
Other thought is that the key is somehow related to the bootloader...It would be good if I could roll back to the original bootloader...Or even use my time machine and stop myself from encrypting my precious data...
I need help on how encryption is implemented on Atrix!
Found an interesting document:
developer.motorola.com/docs/using_the_advanced_encryption_standard_in_android
The problem is that it's app related...
I was wondering, if the Atrix uses the fingerprint to generate the key used to encrypt...
No one knows anything of Atrix's data encryption system?
Maybe it's not AES256...
developer.motorola.com/docs/writing-fingerprint-enabled-apps/
This means that the fingerprint does truly participate in key generation, also that the key will never be the same due to fingerprint images stored will never be the same, meaning that its impossible to re-generate the same key.
Unfortunately this does not talk about location of generated key, nor the name of the key or any useful details about encryption...
Hope is fading away, maybe I should just format everything...Why did I unlock bootloader...Damn app2sd!

Oh, you must be talking about the "Atrix HD" with encrypted bootloader.
Then you're in the wrong forum, this is about the "Atrix 4G", the first version of the Atrix, which can be unlocked.
The only suggestion I got for you is to try to restore the bootloader, or wait forever till they release a way to unlock it...
www.themorningdump.com/2012/07/11/a...oviding-user-unlock-method-is-motorolas-goal/
I searched the web and unfortunately there's almost no info about restoring the bootloader of the "Atrix HD". Sorry.

yeah, i sent my atrix in, and got back a NEW atrix, but its locked and its made out of **** materials. I used the cmd looking unlock (petes or something), but the standard wouldnt work, so i used the fix bootloader option and now it says unlocked when i boot it up, but after installing a rom through CWM, it just stays at the boot screen. Is there an alternate unlocking method that you guys can help me with? when i got it back, it has android ver.: 2.3.6, build 4.5.141, and kernel 2.6.32.9

Maybe you should try another rom, because if its said unlocked at the boot screen, then your atrix is truly unlocked.

Notes on the implementation of encryption in Android 3.0 said:
The actual encryption used for the filesystem for first release is 128 AES with CBC and ESSIV:SHA256. The master key is encrypted with 128 bit AES via calls to the openssl library.

I've tried opening some encrypted files with notepad, and all of them have an interesting header containing almost same parameters...

There have only been a couple of reports of this "new" unlockable bootloader. Given the number of posts we see from people who have not successfully unlocked their bootloader via proven methods and have then unlocked once they have asked for help, I am inclined to believe that there is no new unlockable bootloader, and that there are instead issues with failed unlocks which people are putting down to a new bootloader rather than what could quite possible be just plain old "operator error"! Seems there was an initial few threads on various forums by the same people which has transpired into this theory. I dunno.............but I find it hard to believe that a chosen few are receiving a new bootloader on an old phone model when so many are returning phones daily and receiving repaired phones which are then summarily unlocked again.

Ummm...Seems wasssabi5's problem was somehow passed as mine...
Here is my problem: All of my Atrix's backup files are ENCRYPTED, including all the photos I've taken and all the documents I've written in it...
It happened because I unlocked the bootloader without knowing that Data Encryption was turned on...
I guess the master key got destroyed and a new one was made...Making it impossible to decrypt the old files...Just like encryption on Blackberry devices

Lock pattern not recognized

Hello, I have lockscreen pattern and my phone won't recognize it, how do I bypass it without factory reset?? Also Wi-Fi and HSDPA are off so from what I know if I get to the google account recovery page I'm pretty screwed...
there's a pretty easy way to bypass it if your bootloader is unlocked and you're using a custom recovery, but you have to google it im afraid
and no, i wont help you via pn.

How can I unlock my phone?

Hi!, I have a RAZR D3 (XT919). It ships with Android 4.1.2, but I upgraded it to 4.4.2. A few days ago, I dropped it, and the screen shattered, the screen itself it's not broken, I mean, it displays what it needs to, but half of the screen lost the "touch" capabilities, meaning that I can't input my unlock pattern. I've tried everything in order to be able to unlock it (do not ask why I need it to be unlocked, I just NEED it unlocked), I tried through ADB, but, USB debugging is not enabeld (it actually IS enabled, but I can't confirm the debugging access to my pc because it does not show up the window that asks for confirmation, and, even if it did, I would not be able to tap it not because of the broken screen, because I think the touch part that is still working is in range, but because it would not let me tap it in the unlock screen), I tried through flashing a zip file (actually, lot's of them) that in theory disabled the pattern... yet, no luck (I'm aware that I may needed to input a random pattern, it didn't worked), I tried a file manager made for recovery mode, didn't worked either. So, in short terms, I tried tons of things to unlock the damn phone (factory reset is not an option) and nothing works. I just don't know what to do, I will be buying a new one, of course, but I need it unlocked right now. Oh, I also tried with a USB-OTG cable with either the pc keyboard and mouse, the device simply does not support it. So... yeah, I'm pretty much screwed. Don't be afraid to post any complicated solution, just keep in mind, to make it as clear as possible, thanks for caring and I hope somebody would be able to help me!

Sorry, I'm not sure that I do (most likely not), even if I did, how am I supposed to browse my files? I can't acces my phone through my pc either unless I enable US debugging (literally, it shows no folder neither files... it's like an empty windows folder), thanks for caring anyway

That's because phone is Pattern locked.
If there is no lock, you will be able to browse your files

i dont have any trick to bypass moto phones for samsung and lg i got
Nevermind guys, thanks for trying to help, but I already bought a new phone (LG F60). It's not that I wasn't gonna buy a new one anyway, but, I wanted to check some stuff on some apps that were on the functional part of the screen, anyway, you said you have some tricks for LG devices, if you know anything to get some tweaking or just for knowledge for any problem that I may encounter in the future, let me know (I don't want to root it yet because I will lose guarantee). With that said, thanks agakn for trying, I hope this is not the only time I'll get to this forum. See ya!

Forgot the password on the lockscreen.

So I have this Sony Xperia Ultra XL39 Indian variant which is locked with password (Not PIN or Pattern) and I have to get access to the internal storage to pull out some images, voice recordings and SMS as it's really important to me. Trust me won't bother so much if it wasn't that important and would have done a factory reset. Is there any way to bypass this password? I am on stock and this phone has never been tampered with in terms of rooting or installing any custom recovery. Any help would be appreciated. Thanks.
Could be wrong, but I'm pretty sure if you use the PC companion by Sony it will ask if you want to back up your files and it will place a factory IMG on the phone.

[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.
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.

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!
