Boatloader - Android Q&A, Help & Troubleshooting

Hello
I recently flashed a custom recovery in my phone without unlocking the boatloader because I had no idea that boatloader has to be unlocked in the first place. Now I don't have a PC but is it possible to unlock boatloader with terminal emulator? If yes please help me with the code.
My device: Infinix Hot 3 x554
Version: 5.1
Kernel Version: 3.10.72+
Build Number: x554-W90918-A2-L-20160607
I used kingroot to root the device.
Thank you

I think your bootloader is already unlocked when you root your android using kingroot and custom recovery can only flashed if bootloader is unlocked.

No I can't boot to TWRP

Unless you can specifically on that device (would be in your devices Q/A or help section) then no. Most of the time, the bootloader can only be unlocked in fastboot mode by fastboot oem unlock or through a 3rd party application (ie HTC). Sorry mate.

Bootloader unlocked for custom recovery?

Could someone clarify this for me:
Is it true that in order to install a custom recovery the XTZ needs to have its bootloader unlocked?
I installed custom recovery on my XZ phone alright without having to unlock the bootloader....

Merry Xmas and Happy New Year
I am new to oneplus x.

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 ¿?

hlp regardin unofficial bootloader unlocking

Hi, frendz pls help me
I have unlocked my bootloader unofficial way without permission from xiaomi, with emmc_appsboot.mbn file replacing in fastboot ROM, now my question is, if i mistakenly flash official xiaomi fastboot ROM without removing emmc_apsboot.mbn file from ROM folder what will happen, will my redmi note 3 brick by this.
Flashing fastboot rom won't brick but flashing miui recovery roms without removing emmc_apsboot.mbn will brick your phone.

Look at the guides how to unlock bootloader, and then reflash the rom. Avoid kingroot!

No I haven't unlocked the hootloader ye as I don't know how to get the unlock code so I did contact to huawei they asked Mr for my imei number and serial number and told me that they will send me a mail.
simply download the current firmware of emui and extract the update.app from the zip and copy the update.app in sd card of dload and power off your device and press all three buttons

Custom recovery issues

Hello
I recently bought a new device (lollipop version) and I've rooted it successfully so I decided to flash a custom recovery because I want to back up my OS before I start flashing xposed framework.
So I searched the net for a custom recovery for my device (Infinix hot 3 x554) and I found one, then I flashed the custom recovery using mobileuncle root and I reboot into recovery and nothing changed my stock recovery was still there, then after booting my device I flashed the custom recovery again using flashify and I reboot into recovery my phone just booted normally instead if taking me to recovery mode, now my stock recovery isn't there anymore, please I need assistant on how to fix this.
My device: Infinix Hot 3 x554
Version: 5.1
Kernel Version: 3.10.72+
Build Number: x554-W90918-A2-L-20160607
I used kingroot to root the device.
Thank you
It seems your recovery partition restores itself or there are specific scripts in your boot.img which restores stock recovery when detects modified recovery. You must install it via fastboot.
Obtain fastboot and run this command (You can have it with Android SDK or you can find it in Google too.).
Code:
fastboot flash recovery *filename*.img
But you have to be sure you have proper drivers for your device.
Okay, but I did some little research about how to flash recovery and I saw something about unlocking bootloader, so could it be because I haven't unlocked my bootloader that's why it didn't work?

Yes. You need to unlock bootloader before flashing custom recovery. Locked bootloader prevents modify stock partition.

So after I unlock the bootloader, should I use flashify to flash the custom recovery or I should just use PC to flash it
