Question can't boot into bootloader after unlocked! - Samsung Galaxy A52 5G

Please help. i'm trying to root my A52s. I passed the bootloader unlock and go on for rooting but I cannot boot into bootloader to run the command. What should I do?

@trai_th do you really mean bootloader?
That's equivalent to downlode mode on samsungs.
It should work with adb if turned on in dev options.
Command: adb reboot bootloader.

How to check bootloader unlock?

Dear all,
Merry Xmas and Happy New Year
I am new to oneplus x.
I rooted using this method i. e. Without PC.
http://forum.xda-developers.com/oneplus-x/general/guide-root-oneplus-x-twrp-pc-t3251027
Then I use flashify (app from appstore) to flash TWRP.

http://forum.xda-developers.com/one...recovery-twrp-2-8-7-0-touch-recovery-t3252840
Then i flash blu_a Kernel.
http://forum.xda-developers.com/oneplus-x/orig-development/kernel-t3250995
How can i check if my bootloader is unlocked? For other phones, my understanding is that as long as u can flash twrp, bootloader is unlocked.
I think you can only check that with the adb tools on your computer.
Command to check bootloader status: fastboot oem device-info

I thought the bootloader needed to be unlocked first before flashing a custom recovery??
At OP, when you flash TWRP via flasify, did you run into any problems??
Just curious really.

I have issues with drivers for my windows. Have Samsung s2, Asus Zenfone 2 all installed so i use the root without pc method. I suspect my bootloader is unlocked as i can flash twrp.
Any master has any idea?
Gosh... Seems like no one has the answer. Need to check via PC.
You have to go to setting / about phone / 7 times on build number to unlock dev options/
Then settings / dev options
5th line is OEM unlock.
How is yours?

I manually did that before all the process in my 1st post.
I think this is to allow u to unlock, not unlocking the bootloader per se.
with adb/PC ? isn't it ?
check status of bootloader
first go to fastboot mode
first power off the device than Hold Volume Up while Power on the phone
than in adb type: fastboot oem device-info
there it should be flagged as true
My opx was unlocked, installed twrp, now.... Back to stock ROM and bootloader now is locked and i cannot unlocked,
What can i do?
Thx

I know but my laptop fails to install adb driver for oneplus x because i have too many phones installed. I uninstalled all drivers and tried installing oneplus x one but it fails.

Based on my understanding, once unlocked, its difficult to lock back. If its lock now, i doubt you are unlocked at 1st place. Pleaae correct me if i am wrong.
Yes. You are wrong.
I have twrp, so i unlocked, but now, i do not know how is locked, because i didnt, and when i try fastboot oem unlock.... No errors but nothing happend.
When i flashed twrp and try cm 13 i flashed, from twrp, the stock zip, 2.1.3.x
And now say that is locked, and.... Never unlocked
PD. never rooted, but when i flashed yesterday CM 12.1, when i restarted my opx to system from recovery do not ask for root from twrp ¿?, when i flashed stock zip, asked me to root from twrp when i restart to system ¿?

Relocking Bootloader

Hi guys,
I got a bootloader unlocked ANE-LX2J and I want to lock it again but I dont know the next step.
I still have the bootloader unlock code and already flashed FULL OTA using TWRP and did factory reset.
So now, my P20 Lite is running pure stock again and ready to be locked right? or still not lol :silly:
Based on what I read here, after relocking bootloader using fastboot oem relock command, the warning/alert that shows when the device is booting is still there and I want to get rid of it.
Thanks :highfive:

Yes, you're ok to relock your bootloader if all partition and recovery are stock and your device is working without issues. After relock the recovery will do Factory Data Reset and no more warnings "your device has been unlocked and can't be trusted"
Boot into Fastboot&Rescue Mode and use this command:
Code:
fastboot oem relock [I][B]yourcode[/B][/I]
Then you enter into Lock Bootloader menu and just follow the instructions.
YES -
NO -

I accidentally relocked the phone by using the hstool method of flashing a full firmware.
it does relock the phone and required me to unlock it again using the fastboot oem unlock code

That's interesting. So all your data was wiped when you used the hstool?
Someone else said flashing firmware via dload method also relocks the bootloader.
hmm i'm not sure.
I'll explain the whole situation.
I had just unlocked the bootloader and installed magisk.
after installing magisk, I installed a few modules, one of which made my phone bootloop.
I managed to get back into fastboot mode, use hstool to select my firmware (224) along with the patched hisuite from funkyhuawei.
after my phone recovered, it seems to have been completely reset and locked.
*edit*
I guess I should also add, I've never installed TWRP on this phone, only patched the recovery_ramdis.img for Magisk

I used the external usb method (where you update using the code *#*#​2846579#*#*) and it 100% relock the phone.

and yes, the same code works to unlock it again. KEEP THE CODE SAFE!

You need an external usb-c drive with some firmware on it.
I initially used v187 from this thread
https://forum.xda-developers.com/mate-20-pro/how-to/firmware-update-187-brings-oem-unlock-t3897301
Since then I downloaded a v206 which works over USB but I cannot recall where I got it from.
Note that you will loose all user data since the phone will be fully wiped.
Also this method requires a phone that is working, as in able to boot and access the dialer and menus.
If I find out where I got the v206 I will post it here as well.
I should also add, maybe it might work with a memory card as well... But this method requires an external source for the firmware since it formats the entire phone
@ xeroxide Thx for your help.
I Try this at the weekend.
If you need to relock your bootloader, this is the process:
Using eRecovery, restore your phone to stock
Once done, boot into recovery and RESET your phone (if you dont, it will not allow you to lock the bootloader)
Boot into fastboot mode (Holding Vol-DOWN, plug in usb cable) , and run the command
fastboot oem relock < bootloader unlock code>
the phone should now ask you that it will wipe your device, confirm,
Enjoy locked phone!

LG K61 (mt6765) root?

Hello guys,
I'm looking root options for this device.
Phone's bootloader is probably locked,since there is no fastboot mode.
I have patched boot.img made by magisk manager for A slot(don't know if need for B slot too?)And probably i need patched vbmeta which I don't have it.
I see there is in firmware kdz Efuse image too,I'm wonder if I format this partition in with special transsion tool,could it unlock bootloader?
Thanks forwardly for answers.

No, those drivers would help if there would be a fastboot mode.
But it just isn't available. It just boots to normal mode what ever you try, eh?
That is normal for most of the LG phones...
I'm looking for days on how to unlock bootloader on this phone,but the big problem is there is NO fastboot mode installed.
Is there anyway to workaround to unlock or to enable fastboot mode?
Is there any hidden method with buttons or something to enable bootloader?
This model chipset is mt6765 and what I have tried is I patched both boot.img from A and B slot and flashes back with Transsion program but aftet first start it triggers dm-verity.
I also tried formated Efuse,LAf_a and Laf_b and VBMeta partitions,flashed two boot.img patched and after that it is again trigger dm-verity,but HOW???
I'm having the same problem, i have an LG K51S, when i run
Code:
adb reboot bootloader
its reboots to the normal state, idk what to do, if you have any information please contact me.
Thanks
just subscribing to the thread, I need to root as well. No info yet found. I need root

Adb reboot fastboot and you'll be in fastbootd which removes oem commands but I've been working with the stylo6 and K51 which I have the ability to unlock the bootloaders and flash magisk patched boot.img successfully to gain root access.

Hi, I have a LG K52 and they have the same chipset as LG K61,
I'm having trouble now trying to root and unlock it, can you please explain how you did ?
The only thing I've been able to so far is to get into fastboot and it's in a very very very dirty way, since adb reboot bootloader won't do the trick I had to type adb sideload radomimage.img to get into recovery menu and finally reach Fastboot, but nothing happens when I try fastboot oem unlock or fastboot flashing unlock or anything else
First the adb command is adb reboot fastboot and you can't unlock the bootloader in fastboot, the tool mtkclient from github will do that, i have a group that I sent you the link to in a message, there are instructions and support in there with now almost 200 members. We are helping unlock nearly every newer LG model and many others.

Question fastboot not entering

i wanted to flash a custom ROM. to unlock bootloader with adb with adb reboot recovery the phone just reboot. developer settings enabled. OEM USB debbuging too. but there is no advanced reboot option in settings. help it's my first time doing this.
I faced the same issue after OOS 12
What i did to fix this issue was i went back to Oos 11 using msm tool and then unlocked bootloader then flash custom rom.
If it is your first time doing all this maybe you will find it difficult to use msm tool so follow a good videk guide on youtube and then try this.
