How can i put password in bootloader (s4 GT-I9500) - Galaxy S 4 Q&A, Help & Troubleshooting

HI,,,,
i have Samsung galaxy s4 GT-I9500 and i want to put password in boot-loader , so im using Philz_recovery and set password in recovery . i need to this to protect my phone if i lost it form any one can to change rom
thanks

Smartphones don't have a BIOS like a computer would. On a computer you can set a BIOS password as it in effect is its own operating system. Enter the password and the BIOS initializes what it needs to do then passes control to the bootloader.
On a smartphone, while there is low level firmware like a BIOS, there is no way of accessing it by the ordinary person, thus no need of a password prompt. The bootloader doesn't have a password because its only job is to set up the device environment for the operating system. Thus the only way to password protect a device is through a pattern lock, pin number, or password on Android's lock screen.
One last thing: Philz is two years out of date. Use TWRP instead.

thanks for your reply , helpful answer , but i want to know how can i protect my phone if stolen that some one cannot change the rom by go to download mode and using Odin so( if i put password in android lock screen , and put password in custom recovery and put password in download mode It will make it difficult to change the rom and make my phone unusable)
any Suggestions
thanks

If you had truly read my post you would have noticed two things.
1. Password protection of the bootloader (and download mode) isn't available.
2. Focus on securing the data.
So the answer to your request for suggestions is simple. Don't lose your phone.

All you can do is encrypt the phone, use Android Device Manager, and use a strong password.

[Q] HELP! My phone is locked with Android Device Manager and I can't unlock it!

Call me stupid, but I'm really desperate and begging for help! I used the Android Device Manager on my Tab 3 8.0 to remotely lock my phone. So it worked. But when I used the password to unlock the phone that was set earlier on ADM, my phone keeps saying that it is the wrong password.
Fair enough, I actually used my home PC to do the exact same thing. I went to the ADM site and set alphanumeric and numerals only password and still, WRONG PASSWORD!
What can I do?! I restart the phone and then nothing worked!
Hello siva992, put it back into the two new password in the computer I use only four digits, not failed. Remember to use new numbers, not the same as you have before. Good luck.
You should contact them for help as if it's not notes fail.
If no other ways then you have to do a reflash with Odin.

i too had locked my nubia device through android device manager.
it can be bypassed by rebooting into recovery mode and you need to format /data and /cache.
after this restart your phone through recovery mode it may take 5 to 10 minutes to finally show "android is updating your apps " something like this.
this method worked on my nubia mini and i thing technically it might work on every android phone that is capable of booting into recovery mode.
this method would not delete your photos,music,etc.
only contacts and app data will be gone,i am sure that won't be an issue.

Extracting media from a locked Huawei P8 Lite with lost passphrase

Hello all,
I'm in possession of a Huawei P8 Lite of which the owner lost the passphrase. The question is whether the photos on the device can still be recoved. The bootloader of the device is currently locked. Debug mode is not enabled (nor is my computer authorized).
I was hoping that it would be possible to unlock the bootloader (which supposedly does not trigger a factory reset on this model?) - and then install a custom recovery from where I could backup the pictures. In order to unlock the bootloader, I would need IMEI-1 + IMEI-2 and the S/N. I was able to obtain one of the IMEIs by typing *#06# on the emergency call screen. Is there a way to obtain the other codes somehow (perhaps via fastboot)? Once I obtain the necessary information, my assumption is that I would be able to get an unlock code from Huawei after which I can unlock from fastboot. (Or does OEM unlock still need to be enabled from the developer options in Android?)
Edit: seems like the S/N is shown when connecting in fastboot mode and listing "fastboot devices".
Edit2: seems like obtaining the IMEI through the emergency call functionaltiy combined with the S/N is enough: I modified the "Product ID Generator" tool to include the "ALE-L21" model, and now it generates valid Product IDs that can be used on the Huawei website to obtain an unlock code.
Alternatively, I've noticed that there's an "emergency data backup" mode on this model, which I accidentally entered. I was hoping anyone knows more about this mode (note that this is different from the fastboot & rescue mode). I got booted into this mode because somehow the ext4 partition failed to mount during one of the many times I rebooted the phone. This mode also allowed me ADB access - however, this was a rescue OS which did not actually contain the user data. I would like to attempt to boot into this mode again, gain root access via a kernel exploit, and either read out the unlock code from /dev/block/mmcblk0p** or directly copy the media onto an SD card. Does anyone know how to "trigger" booting into this mode? The kernel code for the p8 lite seems to have a flag "CONFIG_FEATURE_HUAWEI_EMERGENCY_DATA" which enables this feature.
Pointers welcome
Note, I'm not desperate to recover the data - but this has become more of a "challenge" I'd like to solve.
Edit: I was able to unlock the bootloader with details obtained from the device. Unlocking the device did not initiate a wipe. Now it comes down to installing a recovery image and pulling the data

Now simply install twrp, connect to PC and you will be able to see all the files in Explorer

With twrp you can delete lockscreen specific files to remove lock

If you think about this, you can see how easy it is to unlock a phone (also for bad purposes...)
Agreed, I'm surprised that Huawei didn't force a device wipe before allowing OEM unlock. Especially because you can obtain all the details you need from the phone to obtain an unlock code on the Huawei website.
I indeed ended up installing TWRP and remove the password.key file to remove the lock

Recover data from S8 with broken screen

Hi everyone!
I broke my S8 screen completely by dropping it (the phone is still working, not know if the touch still works).
I want to recover WhatsApp backup folder and DCIM folder (i had no backup service enabled, nor samsung account, nor google photo or gdrive), so i thought to go ahed through ADB. Anyway adb list no devices until i unlock my phone through pattern code ( i had no facial/retina/fingerprint mode set).
So i thought to proceed through download mode, flash twrp through odin and access adb through twrp. Anyway it looks like i cannot use odin to flash until i trigger on "OEM Unlock" in developer options which i can't do no more cause of the broken screen.
Is there another way to enable OEM Unlock which doesn't require touch input? Or is there any other way to recover my two folders?
A big thanks for everyone who could help
You can use an otg adapter and a mouse and try to replicate your pattern code and after your in just transfer your files. If you happen to have a second cell phone I would suggest you practise a bit on that screen first so you can replicate the exact movements to unlock your phone. Had an issue with my s6 edge and that worked like a charm.

If you don't know how to recover data from S8 phone, just use an Android data recovery software, it can help you recover data from an broken Android device, it is really simple to finsih the recovery process. And you can preview and recover the data from your broken phone, so that you don't lose these data.

Yep, that's the best thing you can do.

Log into Samsung Find my mobile. Use your Samsung Account details to log in.
There you will see alot of options that you can perform on your Galaxy S8 remotely.
Use the remotely unlock my device option to unlock your device.
Then connect your phone to the Laptop or PC using data cable and recover the data.
Hope it helps.

Any help here?
odd question but... where did you get the phone? can you root it? unlock the boot-loader? it is locked to whatever that company it via their MDM policy.
https://www.linkedin.com/company/groupama-protection-juridique/
if you can unlock the bootloader i assume you could restore via fastboot and that would unlock it. then again, it may brick you phone.
or thy this
On the managed mobile device, go to Settings.
Navigate to Security.
Select Device Administrator and disable it.
Under Settings, go to Applications.
Select ManageEngine Mobile Device Manager Plus and Uninstall the ME MDM App.

How to bypass FRP Locked after factory reset

I recently purchased a used A20 (SM-S205DL) the previous owner's child locked the device and forgot the pin. I was told it didnt have FRP activated so i mistakenly hard reset it without checking odin mode first. Now i have no way to set up the device or enable usb debugging. I have firmware and some basic knowledge of flashing via odin. Although i have only used it to unbrick a device roughly 5 years ago. How can i either remove FRP via odin mode or download mode without usb debugging turned on. I have no preference on how to gain access to the device. If frp cannot be removed could the device be completely wiped and made into a basic Linux device? I have no preference on what is done i only want to have some use out of it
Factory Reset Protection exists to prevent the use of stolen devices. Unfortunately, this can become rather inconvenient in other circumstances where for some reason the Google account the device was locked on isn't available.
While FRP unlock services exist, we here on XDA tend to err on the side of caution due to the potential for criminal activity.
Try flashing vbmeta.img (UNLOCK BOOTLOADER)
Try this:
This device was reset. To continue, sign in with a google account that was previously synced on thos device.
