bootloader in ICS is locked. Nothing to do about it, for now... later we'll see but, once in JB I don't believe
that someone wants to remain or go back to ICS.

Ok..tnx for clear answer
First welcome to our forum , I hope will find what you need .
Why do you want to know 'how to check' .
It's locked in ICS , unlockable in JB (for devices are EUR-xxx ,, after flash JB see the software info in settings) .
You can check it by :-
Code:
adb reboot-bootloader
Fastboot flash kernel xxx.img
Then you will get an error says :- error partition is locked .
Update your phone to JB and then unlock it , then check it in the hidden menu (3845#*880#) , goto bootloader status (or something like that) then will see it "unlock" (of course after you unlock it) .
About check them in recovery (like HTC devices) , in LG you can check them in download mode , you will see "unlocked bootloader" in the corner of screen .
to get any help we are here and you can ask us as much as you can .

Hello guys,
Well... I guess I got one of the dumbest operator rom ever made for XZ (guess it's the same as Vodafone's one), so I wanna root it to get a recovery and then flash any kind of others roms but it's still weird..
By typing *#*#7378423#*#* => Service Info => Configuration ; I was (and I'm still) on the "Rooting Status : Bootloader unlock allowed : No"
So, I do Install the ADB Drivers from this Thread
Then I try the Binary's script, but still no reaction on the 2nd step (yeah I do launch it as administrator), and then I use the DoomLord'd recovery for locked bootloader
So now, I got the CWM 6.0.2.8 recovery on my phone, but I still got the "Rooting Status : Bootloader unlock allowed : No"
Well... I just dunno where I am... Do I am rooted ? Can I flash a custom rom ?
Help

Frnd, Make ur basics clear.. Rooting different from installing custom roms. To install a custom rom u need to unlock the bootloader first. But to root your device, you dont need the same.. Please search the forum once again.. u'll get the answer

I do check what I can since weeks now, and wait till safer way get released (seems cool now ?..)
So I do try the "official" way from sony to unlock the bootloader who just tell me "lol Bootloader unlock allowed : No"
Then.. I would like to unlock the bootloader yeah...
What do I mean to learn ? for now : locked bootloader will stay locked... (I'm still in that feelin that nothin is impossible)
So yeah I search on the forum to "make my basics clear" ; here we go => Usefull forum search
So, what I meant to learn now => I just can be rooted for now, but the Bin4ry's script don't work for me and I still dunno why
But... I success to get the CWM recovery on my phone through DoomLord'd recovery for locked bootloader
Questions was :
Can i flash a custom rom through CWM ? y/n ?
Usually on my previous phones (HTC Leo, HTC Desire, Samsung G2, Samsung Galaxy Nexus) as soon I can get the CWM on my phone mean that I'm rooted, so ?....
You can flash roms that are for locked bootloaders, they are usually indicated by [LB] in the dev threads. The bootloader unlock allowed status for your device will remain no, root does not magically allow you to unlock your bootloader.

Try roll back to v10h(if that is your latest stock for your phone before official JB update), than use LG Mobile Support Tool (official) , and try to flash your phone with "recovery phone" option in Customer Suport menu in LGMobile Support Tool!
And if you didn't before, try first to use reset and clear cache partition from recovery!
(Make backup of important stuff ..apps, pics..)
Or try to wait a little longer than 30 sec next time..

Some new info about unlocking from LG:http://forum.xda-developers.com/showthread.php?t=2224020
Hi there.
After i unlocked* the bootloader of my phone i got stuck in a bootloop, then i had to flash the TFT all over again...
The problem is that i don't know if the phone is already with bootloader unlocked or not...
how can i check it?
I was thinking on trying to do the unlock steps again, but i'm scared of being trapped on another bootloop...
Is there a way to check if the bootloader is already unlocked?
PS: The bootloader unlock allowed is yes.
thanks you guys.
Flash doom kernel via fastboot with this command:
Fastboot flash boot boot.img
If you get an error than your bootloader is not unlocked.
You can flash back to stock kernel with flashtool,flash the kernel separately.
Sent from my C6603 using xda premium
but if i got that error and confirm that the bootloader is locked, is there any chance to harm the phone? or need to flash the TFT again, etc etc
use flashtool to tell you
Another more easy approach .
When bootloader unlock allowed says yes and be2 is working in Album, then it is still locked and you can start the unlock steps again.
How can i use flashtool to tell me?
@DevShaft
Before i could see in a flash the bravia engine working on pictures. There was a little delay... Now i can't see it.
Probably the bootloader is unlock.
If i try to install Doom's kernel via recovery and the bootloader is LOCKED, can it do any harm? thanks guys

I unlocked my Xperia Z and in Service Mode I can see 'Bootloader unlocked: Yes'.
Now my phone is running on latest C6603 firmware and DooM Kernel.
To my surprise, BE2 still works! Music info download still works! TrackID still works!:victory:
But not picture enhancement in album right? Hope you backed up TA partition before unlocking

im surprised at how this 'check bootloader is unlocked already or not' thread is confusing.
by the previous post, there is two 2 ways
1. try to flash doomlords kernel via fastboot, and if it doesnt flash means its NOT unlocked.
2. flashtool.
however the 2. flashtool method is very vague.. dont think anyone elaborated it.
So my same query is that if some error occurs after trying to unlock bootloader, and have reverted back to the stock FTF rom in original working state.
How do one check to see if my bootloader is unlocked or not?
whats the best easiest method???
Thank you!
just type in *#*#7378423#*#*
Go to Service Info > Configuration
And check the Rooting Status
If its Bootloader unlock allowed:Yes/No, then its not unlocked.
And if its Bootloader unlocked:Yes, then its unlocked.
Thanks

That just tells you weather you can unlock your bootloader via the command / flashtool e.g. If you carrier has locked your phone
On a unlocked bootloader the BE2 engine still works on videos ect just not pictures.
All I would do Is flash doom kernel or advanced stock kernel via flashtool (Click on lightning bolt /fast boot / click on put device in fastboot via adb now phone will enter fastboot then select kernel to flash which is in the middle on the pop up screen and then flash if it will take around 0 . 5 seconds ) if it fails then you bootloader is locked due to it cannot complete the command if is successful then it's unlocked and you can flash custom kernels take about 2 mins to do all in all

Can any one tell me how to unlock bootloader for SM-G350E
Hello,
I just unlocked my bootloader, made a data restore, and everything seems to be fine.
But, when typing *#*#7378423#*#* the service menu does not appears (code is deleted from dialer but no menu). Don't know if it's normal on cm11.
I'd like to check if the bootloader is really unlocked before trying a 5.1.1 rom ... to avoid bad surprise ...
Thanls!
Hmm, the service code should work no matter what ROM your on..
You also van check with flashtool..
Thanks. Do you know what fastboot command to see if BL is unlocked ?
I meant flashmode and a programma flashtool on tour PC. Look here: http://forum.xda-developers.com/showthread.php?p=43355810
I didn't find a place in flashtool that shows the bootloader status ...
So, what can I do to make sure my bootloader is unlocked?
Only way is too flash a stock rom? no magic command or utility?

In this case I am unable to help you, but you can use dc-unlocker paid service.
It is here:
https://www.dc-unlocker.com/huawei-android-phone-frp-unlock
Sorry I never used it so can't give more information, you have a look and decide.
@Snober
you have now FRP-Lock ?
have you twrp/backup from last state (before install kangvip)
then test twrp/restore and look if phone work FRP=unlock
it is better if you need help - give more info : what is your build ? LLD-xxxxxxxx / what is delivered OS ( first delivered "7.xx", current "8.xx")

No sir i don't have backup of last state. And i can't go to twrp as i installed stock recovery
My build is 8.0.0142 c675 indian version
Now there is another problem now. I searched for solutions and got the answer as to relock bootloader. Then i relocked it with fastboot cammand. Now the phone is bricked and restarting to erecovery after honor logo. Currently status is phone relocled and frp lock in fastboot.
Please help
@Snober
sorry, now you have big problem !
Relock Bootloader is the greatest Bull**** by phones ! (my opinion !) if you relock bootloader WITH damage-rom you have a "damage-phone" !!!
please search "repair bootloop with bootlooder relock".
for future if your phone again work
- unlock bootloader AND let it open
- download your build FULL-Update (now you have backup for repair - if needed)
this 2 point's is very important
i think you have 1 chance to self-repair : search "recovery_ramdisk_BKL-L04_nocheck.img"
but - this is no simple. you must read and understand before you do ! I DONT KNOW if this work for you !!!
@JamesBott
Isn't it possible to unlock the bootloader again after relocking?
@BS4388
usually yes, but if you relock bootloader WITH damage-rom you have a "damage-phone" !!!
that's the point. if user install dev-rom and this work not 100% good AND then relock bootloader ...
if now bootloader locked - you need "fastboot flash oem unlock your-unlock-code"
if you have FRP-lock you dont can "fastboot flash xyz"
my friend have many "help me" from other user with this problem
he found the way with "recovery_ramdisk_BKL-L04_nocheck.img" and say - this work only if on phone twrp installed BEFORE error AND boot to twrp work
usually you can bootloder unlock and relock with your-unlock-code many (not once only)

Well, I think @Snober can still revive his H9L by flashing a stock firmware using a paid service such as dc-unlocker bypassing the frp lock.
@BS4388
i dont know if dc-unlocker work with frp lock.
but i think it is a test worth - only it cost 15€ (ca. 15$) (if not work only 15€ lost - new phone cost 230€ [in germany])
i think if it's not work, dc-unlocker rewrite money to user-account. but my last dc-unlocker use a little time before now
I am sending my phone to friend as there is no service center in my location .
Should I send .
Can the phone be warranty as my phone status in fastboot is phone relocked and frp lock .
Will they detect the phone was unlocked or something like that . I mean will any problems comes . ?
Got My phone repaired in service center for free. They didn't see as the phone was in relocked state. So happy ?
this is very very good for you
BEFORE you any things do in future with your phone - YOU NEED FULL-UPDATE on your PC

For future reference: Stock ROM appears to require a network connection in order to enable FRP, so, connect with WiFi and it should become touchable.
