Might this help with US Model/Version? [Trying to unlock bootloader] - Samsung Galaxy A50 Questions & Answers

Hi?
I found something, and I was wondering if anyone might know what this means?
E:[libfs_mgr] Unable to disable quotas on /dev/block/platform/13520000.ufs/by-name/userdata because /system/bin/tune2fs is missing?
I was wondering if "tune2fs" that is missing, could be the result of not having settings to OEM Unlock? And if so, does that mean, if we can possibly use ADB to maybe put this "file" in there? Would it make a difference?

It wont let you until you app unlock your phone. I am attaching the file you need to run to accomplish this. After you run it you will be able to edit it.
copy it to your phone and run it.
Tried that, does not work on WM6. Anyone else have an idea what I can do?

it worked on mine and I am running WM6. and just to make sure you are editing the IE_Short.lnk file not trying to rename it right?
And make sure that you reset the phone after runninig the patch.
I know someone who was trying to run something that required a command line argument (Right Menu) using the shortcut, and they couldn't get it to work. Anyone know of a workaround?

[Q] Unlocking defy bootloader

Hi, everyone knows that the atrix is unlocked and some people is looking for doing the same on the defy.
what we have to do is activate the cloud function, choose a server and the phone will look for an update.zip that will maybe unlock the bootloader.
If it fails we have to wipe the phone, choose an other server, and try again
My question is : is a faster way exists ?
for exemple i was thinking about exploring each server with a PC, but when i've tried i've only found a crossdomain.xml file on it. Maybe the phone is looking for an update.zip in an hidden folder.
Is someone knows exactly where the defy is looking for updates ?
when we will know that maybe we can found an file with explicit name like "unlocked-bl-update"

unlocking question due to the amount of threads

usually phones are locked by imei no. so will work only for that phone
if you try this on other phones is to get an error message only -so will not hurt to try but no results also if you try 3-5 times an unlock code phone is hard locked - only service tools(/unlock box/dongle) can reflash /unlock it
stupid noob question
u said unlock box/dondle? what are those? service tools.
so i guess my question is this. is the unlock code somewhere on the phone is there a way or person who can help me find it without going through tmobile

it's hard-coded in radio firmware you can't find it so easy also it depends of your phone model i.e. look here to see how to unlock a galaxy i-9000 phone
ok im working with the garminfone on this project. and when adb it doesnt recognize this device. any clue on how to arrange it so it does. it will connect to the computer and i can see the files from there but it just will not be found as a device through adb

as I said you will not solve that problem...
to make Garminfone to work on PC install Android SDK and phone drivers (from CD or Garmin site or just install sync software and you get it) after installing SDK and drivers you should get ADB interface working check this by running adb check from console (cmd.exe) don't forget to add adb location to system path or just enter adb.exe folder before usually the folder is ~\android-sdk\platform-tools\
now check your ADB interface is working open cmd.exe in adb.exe folder then
Code:
adb devices
if you don't get this your phone will not work with PC
don't forget to activate usb debugging on phone

[Q] Default bootloader entry

Hey guys, I'm wondering if anyone knows how to view the bootloader entry for the note 4. I know it is 'locked' but has anyone been able to even access the configuration file?
I work in the open source community and have some tricks of the trade that could come in handy if someone can 'show' me how the kernel bootloader is structured. The trick I have in mind has to deal with interupting the boot process after all file systems have been mounted and before control is handed to the system daemon.
Let me know

Have you tried posting this question in the Lets Talk Root! thread? I wonder how many devs read the Q&A forum. Just a thought.

Bootloader unlocked warning

Hey,
I've been researching the OP3 bootloader and the bootloader warning and I've found a possible method to hide it.
There is a file "emmc_appsboot.mbn" which contains information and strings (see content below). I'm not sure if modifying the file causes booting problems. I've examined the file and found something about verifying various files and blocking the boot process. I'm looking for someone who could help me and explain things. What do you think? If it's going to brick, would it be unbrickable?
Strings:
"Start >"
"< More options"
"Your device has been unlocker and cann't be trusted"
"To learn more, visit: g.co/placeholder"
"If no key pressed:
Your device will boot in 5 seconds"
Something about blocking the boot:
This phone has been flashed with unauthorized software & is locked. Call your mobile operator for additional support.Please note that repair/return for this issue may have additional cost.
boot_verifier: keystore length is invalid
I'm thinking about replacing all these texts with spaces to make the screen look blank. That's the way to "hide" the text, but there's still going to be the 5 seconds delay.
Download link to the file: http://d-h.st/SQID (Uploading attachments wasn't working when I posted this)
EDIT: Feel free to examine the file with a hex editor. Search for those strings to find the position.
There're already two threads dealing with the bootloader warning:

I know, but neither one is dealing with this exact file/method. There is of course the "logo.bin", but I don't think it includes the warning message as I've found it from the file I discovered.

the "warning" message is inside the aboot....at the moment there's no way to modify this file....but....we will see.

Isn't it possible to modify the hex codes? Or is it the verification that is the problem in this case?
Edit: I've seen that people edit this file with success.

where did you see it running?
editing is not the problem, flashing it back is not the problem...but the phone won't start, even if you change a single bit !
there's an checksum active even if you set your phone to unlock_critical...

It was a Samsung and a Xiaomi device (partition and bl unlocking stuff, so not exactly related to this). The checksum is what I'm after.
Unfortunately I don't have enough experience and I don't know if it's even possible to do this.
I'm wonder what exactly happens if I edited the code to have only "spaces" or "NBSP".
Would I get any response from the device? Would I see any error codes on the screen?
I'm too unsure to risk my device. But thanks for the answer!
if you not know how to use the OP3 unbrick tool, let it be..in result you got an unbootable device if you change anything inside the bootloader.
It can't be changed.
