[Q] dont know if i have to unlock bootloader first

i recently switched to teamwin and i was wondering do i still have to use ez unlock to unlock the bootloader???i was using cwm with ez unlock and ez recovery..i go through goo manager and hit reboot recovery from there it goes into teamwin,do i have to use ez unlock first then go into goo manager?? please let me know..thanks..
You only need to unlock the boot loader once. As long as you didn't specifically lock the boot loader or flash back to the stock image then you still have an unlocked boot loader.
thank you for the reply

[Q] Is my Boot loader unlocked? how can i know'

Hi all, my phone is stuck in a boot loop. Im not rooted. im trying to find ways to save data from my the phone before i do a factory reset.
I read a useful thread here, where someone posted that if the bootloader is unlocked, the data could be saved. If it was locked then it cant.
I think in the Boot menu it should say something about locked or unlocked. but in mine it doesnt. I enter the Boot menu and it just says:
HBOOT 0.98.000
then i have these options:
fastboot
recovery
factory reset
simlock
image crc
btw, its a HTC desire (bravo)

I'm not sure I completely understand you. When you try to unlock the bootloader does it stay locked? Or does it unlock?

Sounds like you have a bad emmc. You likely need to send it in for repair.

That sounds a like you have a bad emmc. it is a hardware failure.

[Completed] Moto G 3rd Gen bricked or not bricked???

Hi,
My phone went into a boot loop.
I can access the fastboot menu but the device is locked, I obviously now cannot enter developer options to unlock it
When means I can't unlock the bootloader, and without unlocking the bootloader I can't reflash the device. Bit of a loop of death
Any suggestions or is it a door wedge?

Relocked bootloader help! pls

So i relocked the bootloader becouse adb did not want to accept any commands.
I had an unlocked bootloader but i have read on the forums that it locks it self but says its unlocked anyway.
So i locked and unlocked the bootloader
And I can't enter fastboot or boot the phone. It's just stuck.
eRecovery does not boot.
All it says is The phone is unlocked and unsafe... Booting ... and nothing happens its just stays like that....
Can someone help me?
