Twrp flash custom kernel on locked boot loader? - General Questions and Answers

I read somewhere that TWRP allows you to flash custom kernels on a locked bootloader . So I'm wondering if it's possible to flash CM or a custom kernel on a LG MS769 with a locked bootloader without possibly bricking the phone???

Please help me Unblock bootloader for Samsung Galaxy Player 5.0 YP-G70 International

Hi Guys,
I don't know if this is the right section to post this question, I'm new in the forum.
I just kept my ex boyfriend tablet and now I'm experimenting with it, but I have a few questions:
If I want to use Odin to flash a custom kernel , let's say rj's Kernel, do I need to have the bootloader unlocked ?
How do I unlock the boot loader for Samsung Galaxy Player 5.0 International version ?
Could you please help me Unlock the bootloader ? Could you please explain if I need the bootloader unlocked to install a custom kernel with ODIN ?
Do I need the bootloader unlocked to install a recovery and then do a Nandroid backup and then install a custom kernel ?
Device:
Samsung Galaxy Player 5.0 - YP-G70 International version.

To flash a ROM or recovery and do a NAndroid backup you need an unlocked bootloader.
To unlock your bootloader, use this Windows program: http://www.mediafire.com/?f3gi19g1zz3frg3
I hope this helps you, but don't forget, with unlocking your bootloader, all your data will be erased!

well with this device im not sure if you need to unlock the bootloader. some need the bootloader unlocked some don't. i would ask in the official forums for the Player http://forum.xda-developers.com/galaxy-player you need to tell them its international as well.
Thanks Guys, it has been really helpful.
Could you please let me know the name of the program I have to use to unlock the bootloader for this device?
I've been reading like crazy and I understood when I unlock all data will be lost, but that's not a problem at all.
Then I would like to flash rj's kernel which comes with Clockworkmod and then from there I would be interested in doing some Nandroid backups and installing cyanogenmod.
In fact I would like to be able to do a backup even before installing a custom kernel so I can preserve the original kernel and android, I installed an application called something like nandroid backup and I managed to do a backup compatible with clockworkmod but the thing is that it skipped the boot and recovery folders, so it makes me think the bootloader is locked.
Please any comments are very welcome.
If there is anyone here from Ft. Lauderdale we could even meet in a mall and do the thing together with the laptop.
Thanks again for all your help honeys

Like I said your going to want to hit up the official forums but I'm keeping a lookout for a way. There has to be a way if there's custom ROMs already

[Q] Bootloader unlock necessary for custom rom with BMM?

Hey guys,
Do I need to unlock my bootloader to install custom roms with BMM?
I already installed BMM apparently with no issues!
Thanks!
Bootloader unlock is for custom kernels
You can install/restore rom's in bmm with 'kexec' or 'stock' kernel without unlocked bootloader.

You can't unlock A2 's BOOT loader.................
BMM works without it and we also have JBX kernel if you want a custom kernel with that ROM of urs.....
Have a look at this thread http://forum.xda-developers.com/showthread.php?t=2472331 :laugh:
For all the GR8 ROM's available for you.......

Nope, there was an exploit in the tz partition to unlock but that's been patched now. You can't flash different kernels or downgrade anything but the system partition. Trying to will likely land you hardbricked

Wraith is correct, you can't flash a kernel on a locked BL.
Thanx for the help, well on optimus g i have flashed both rom and kernel on the locked bootloader, through 2nd init cwm recovery.

[Help] Can't install custom recovery !

Hello,
I have some problem to install custom rom and recovery on samsung US device
Can I unlock bootloader for this device ? what I should do to install Custom recovery ?
Thank's
Sadly, you cannot unlock your bootloader past the 4.1.2 update (excluding 4.1.2), and the only custom recovery that works is SafeStrap. All of the ROMs you install past said update must be on the TouchWiz kernel, so there's no escape.

You're going to have to provide a lot more info cuz that doesn't make sense. Flashing a custom recovery on a Verizon S3 (SCH-I535) with 4.3 or 4.4.2 causes a hard brick upon rebooting the phone.

ok, what can I do now to install a custom rom to get another language and get mmi code when I'm looking that ?
Thank's

(Q) Install Xposed with no custom recovery?

Hi, I would like to know if it is possible to successfully install xposed on Moto Gs without having a custom recovery installed. I'm asking for this because I don't want to mess too much with my phone and to keep it as clean as possible.
Thank you
Moto G XT1032
Rooted
5.1 Brazil
Bootloader unlocked
As far as I know there's no possibility to install xposed for Lollipop without custom recovery. But I don't understand why you don't want to flash a recovery when you have already "messed" your device with unlocked bootloader and root! It is just one step forward.
Sent from my XT1039 using XDA Free mobile app
Well the bootloader can be locked again and the root can be removed as well. Maybe custom recovery too?
Alternatively, can the custom recovery be flashed temporary to then flash xposed?
But even if you lock it again motorola already knows it and when you lock it again it will show a different code from the original locked one
You can temporarily boot into a custom recovery and install xposed.
Just type fastboot boot <thenameoftherecovery>
