Samsung SPH-M820 Boost- Password Bypass

Hello,
I have an old phone I would like bypass/remove screen password without loosing my data. I have done some research and based on the following bullets I don't think it's possible but wanted to run this by the professionals for confirmation. Thanks very much for your time!
non-rooted
no USB Debugging enabled
Stock-Rom
Stock Recovery
No CWM
No Internet Connection
No service
No google verification
Additionally I have tried applying update.zip using Pattern Password Disable.zip but if fails because of signature verification.

Screen locked - how to retrieve data from the phone?

I have a problem with my Xiaomi Mi 9 Lite. Some time ago I've setup a screen lock with password I can't remember. How can I disable it? USB debugging is off, bootloader is locked, no custom rom/recovery is installed. What I want to achieve is to not lose any data so in this case is there any possibility to copy the data from the device?
Thank you for any support.
Contact to your service provider or product manufacturer provide them with the information they ask for, and see if they can help you. They are the only ones who will assist you in these matters.

The door to any Android device is ADB ( read: Android Debug Bridge ) enabled ( Settings -> Developer options -> USB debugging ). This is the first setting every Android user should make when he starts using an Android device. Doing so then most problems can get solved by user itself.

Searching for Huawei P30 Lite MAR-LX1B unlock

Hello.
I'm searching a WORKING method to unlock the 'Huawei P30 Lite MAR-LX1B'.
Emergency-Call Code is not working anymore.
Emergency Backup function is not available at this Model.
Callback or Safemode exploit don't work, too.
ADB is turned off.
Tried very much methods that are on youtube, but i think these all are too old now, nothing is working.

How to bypass Google-Verify

You can do it by
either
fastboot - what requires device's bootloader gets unlocked before
or
avbctl - what requires ADB runs in root mode
Both scenarios are not given here.
NO ADB
NO ROOT
Just made a factory reset and then google want to ****s me up...
Just recovery and download mode possible.
I have no access to enable ADB or ROOT or whatever, because i haven't the Google account for that phone.
How does Huawei reset it? There must be a way to do it without the account.
Is it possible to generate the unlock code?
As I can see you're confusing things.
DM-VERITY / AVB protects phone's Android OS getting changed, not to get into phone's Android OS what FRP-lock ( which is tied to your Google account ) does.
AFAIK to programmatically remove a FRP-lock phone must be accessible via ADB and Andoid OS must got rooted.

Secure while bootloader unlock

I have a few questions about being secure and things with the bootloader, and stuff like that.
#1: Is there anyway to be secure or thiefproof or even law enforcement proof with an unlocked bootloader?
#2: How does encryption work on Android. It Full disk encryption forced on by default, because I don't see the option anymore (except for SD card) How does it work? Does it encrypt the device till turned on? Till lock code in entered? Is it only there when there's a lock code? Does it work like Bitlocker?
#3: I wanna unlock my bootloader and install Lineage or Graphene OS. Since I can't relock the bootloader with custom rom or recovery (considering I have AT&T LG G8 THINQ and Xperia 5 II) can't anyone just flash TWRP or something, and even if the data's encrypted, just delete the security settings to bypass the lockscreen as shown in MANY tutorials and get to all my sensitive info and functions that way?

General ROM2box - EDL, Scatter, FRP etc... multi-tool

Hello again, just wanted to share something I somehow missed a while ago but feel it would be helpful to many N20 5g users. It's ROM2box and works for FRP unlocking, edl flashing, scatter flashing and many others. This is not mine but I wanted it to be easy to find for the rest of you so here's the link to the thread where it can be found and our device among others is clearly stated as supported.
(Tool) ROM2box All in one FRP, Flashing & unlocking tool
ROM2box is a Powerful tool and GUI bring all the tools on a single app. it support qcom mediatek and spreadtum phones. Supported Functions- Function Name Status bypass Auth Yes bypass FRP MTK yes bypass FRP qcom yes bypass FRP samsung...

be very careful with this and for the sake of sanity please make sure you have a full backup of ALL partitions before using rom2box for ANYTHING. i know that if anyone is trying to use it for the frp unlocking it probably means u dont have access to be able to do this in the first place but i suggest only attempting anything without backups if you can accept the risk of completely and possibly permanently bricking the device.
