How can I unlock my bootloader and get my phone to reboot and recovery mode
Related
For the sake of this question I have a locked bootloader on a wt19i. The phone is rooted. (It's my friend's phone but I'm voicing a theory). It can't enter fastboot mode and the bootloader unlock status is: not allowed.
Armed with the IMEI number,
If I did a TA backup via Octopus Suite 1.0.3,
Then, (following methods seen in this thread: http://goo.gl/QNKxS Third post down.) to force the phone into fastboot, start a firmware (re)install in PC Companion. During that process the phone will enter fastboot mode. If I stop the process there [in Windows Task Manger], then the phone will get stuck booting only into fastboot mode (until I finish putting firmware .tft back on it).
THEN I use SE Bootloader Unlocking v1.6 {Found here: http://goo.gl/JxDmY }. I give it my IMEI, it gets an unlock code and I connect the phone - in fastboot - and select "Unlock BL" to unlock the bootloader.
Then restore TA, followed by a restore of firmware.
Would this unlock the bootloader or brick the phone?
Corrections and answers welcome.

I checked the thread you were referring to,
the process they are doing there is to access flash mode...
fastboot is completely different, can only be accessed if bootloader is unlocked.
based also on the bootloader unlock status: not allowed, this means phone is network locked, unlocking of bootloader would not work thru available methods in xda.
you would to pay in order to remove the network lock and then unlock bootloader

This would not unlock the bootloader,
Brick the phone, not sure, but it would probably wont, good thing you have a backup.
You can always do a flashing of stock firmware thru flashtool or wotanserver.

You can't unlock if it says

If it says

If it says
Bootloader unlocked: yes

your bootloader is unlocked.
You can check the state if you boot phone up, open dialer, type *#*#7378423#*#* -> Service Info -> Configuration
Please tell us what it says there, then we can help you

The problem is you tried to use that tool and the moment you have typed your IMEI and pressed get unlock code, you lost your warranty. So you have no warranty anymore!!
Now you will have to desimlock and after that you can just hope fasboot is enabled.
Install flashtool, open the installation folder > drivers and install all drivers for all devices. Install the android sdk (please better look in my signature to see how to set up android sdk and flashtool and replace the usb drivers). Then try to enter fastboot mode like explained in the threads
I have a little isssue with the bootloader...
Sometime ago, i have unlock the bootloader easily, no problems.
But now, i have checked if it is unlocked, and it is no longer
So i have tried to re-unlock it, and fastboot display that's okay and my phone reboot into recovery.
I have rebooted it into bootloader mode, typed "fastboot oem device-info" and nobody is true !
What do you think about this ?
Ps: Sorry for bad english
Okay, calm down.
Go to developer options and see if "OEM Unlocking" is enabled. If not, enable it.
Cool. Now enable USB Debugging, connect the phone to PC, open CMD and type
Code:
adb reboot bootloader
then
Code:
fastboot oem unlock
Download TWRP from the official website, rename it to recovery.img and then
Code:
fastboot flash recovery recovery.img
Now you have a recovery and an unlocked bootloader. Profit?
I hope this helps.
Thanks for your reply, but it doesn't work
I have only my old recovery (who is twrp in is latest version, no problems with that )
But suddenly i wondere if unlocked bootlooder is useful if i have already an recovery
Finally, i have followed the mega unbrick guide.

Hi there every one i'm a newbe pls help me .I need to root my samsung j 1 ace sm-J110H Phone ,I tried to unlock my bootloader with adb in developers options there is no oem unlock ,adb can read my device but when I try to reboot bootloader it reboots in normal mode and not in fastboot mode. My question is how to solve this problem
(is there another way to reboot in fastboot mode) and is there another way to unlock my bootloader or there is another way to root my phone without this step.
Up
I have an LG G5 H850 which got stuck on Fastboot mode overnight. It can not access any other boot mode, only Fastboot.
It wasn't root nor had the bootloader unlocked. When I try to do that (fastboot flash unlock unlock.bin), I get the message "remote: oem unlock is not allowed" because OEM unlock option was not set, but I can't set it since I can only enter Fastboot mode.
Is there any other way to activate OEM unlock option?
I'll really appreciate any help I can get.
Thanks in advance.
Same here.
Stuck in fastboot OEM Unlock mode.
Trying to enter bootloader mode shows only for less than one second bootloader mode and switches again into fastboot OEM unlock mode.
A little late here, but can you flash the factory image with LG software so you can boot back to the OS?
Hi !
I try to flash twrp recovery. It seems to work fine but then, when i boot, i go back to fastboot mode. I tried to pull off battery but did'nt work.
Help would be appreciate
