[Q] Unload Bootloader for 20A-ESA-XXX - LG Optimus 4X HD

Hi guys,
First i would lie to apologize to start this thread, as many have threads with a similar question were been asked. As I still cant find the correct answer, hence I am starting this thread.
I am currently of JB Stock ROM 4.1.2(20A-ESA-XXX) and i have just rooted my device few mins back without any kind of hassles using the the method given in this link (http://forum.xda-developers.com/showthread.php?t=2180688).
I am willing to install a custom rom, but without unlocking the bootloader it wont be possible. Request you guys to direct/show me the correct way to unlock my phones bootloader.
Thanks & Regards,
Bhavik

Help a newbie ?

I know this is probably one of the most FAQ about here, but despite this I can't find the answer with either of the two search facilities.
Using this forum, I unlocked my phone with the pay method.
I now need to flash an original ROM (or even an original looking ROM) and hopefully still keep the phone unlocked.
Can someone point me in the direction of the relevant threads ?
Thanks for the help !

You need to do a Hard SPL before ANYTHING else.
all you need can be found in the stickies in the ROM section.

[Q] Interested in rooting and flashing a custom ROM for the LGOB. [Q]

Hello guys, as you can see I am new to the forum and new to android in general. [Used to be an iOS fanboy] I have recently acquired an LG Optimus Black but i'm unhappy with the stock ROM provided by LG.
I have a few questions:
1) What are my options for rooting the device?
2) Once rooted, what custom ROMs are currently available for the device?
3) If I flash a new ROM is it possible and what would I need to have/do to restore the device back to the stock ROM?
And lastly...
4) What is the chance of fully bricking the device and what are my options if the device gets bricked?
Thanks a lot, [Hope this was the right section and hasn't been asked before...]

All was asked and ANSWERED before. Move your a** and search for it.
I have searched actually. The questions that have been answered aren't specific to my situation and I know that small details are very important when flashing phones. If you aren't answering the question I guess what you posted would be considered spam?
Guys,
Please refrain from bickering, two ways this can be easily resolved:
1. Use google search with the word xda in it to find your answer
2. Rather than posting move your a** and find it, if you know the link or answer, why not help a brother out?
I will say no more on the matter, its that simple.
THanks.

No point arguing..if you don't wanna help just ignore.
If you wanna reply, make sure it helps others.
1) What options? It's either you root or you don't. Either way, your phone works.
2) Currently there's only NOVA Rom by knzo.
3) Read this thread here.
4) Chances of bricking are slim if you read before attempting anything. If in any case your phone is bricked (boot loop), refer to the above.
Hope it helps.
Welcome to the Android community
Thank you very much for the very active response and information.... I am also studying these issues.

Exactly what I needed, thanks a lot!
I've heard a lot of the current roots don't work for the OB?
And is NOVA the ONLY ROM at the moment, I thought I heard about another one?
Older firmwares, you can use Gingerbreak. If it doesn't work, then most probably you're on the newer firmwares. Then use SuperOneClick.
The other one is Pays ROM. It's been abandoned.
It needs v10b Firmware to run. If you're not familiar, stick to Nova ROM.
Cyanogenmod is in progress (i hope so)

[Q] SIM Unlocking Xperia T

1) Rooting and unlocking the bootloader has nothing to do with sim unlocking. Flashing a custom ROM will NOT sim unlock your phone. Goto a paid for site or speak to your carrier to get sim unlock.
2) There are loads of guides in this forum to root and unlock the T, no need to look under other device forums.
3) Is this a question? I think so for several reasons.....one, I answered it, two, you even said it was a question in your title....guess what, it should be in the QUESTION AND ANSWER section.
Thread moved. Please post your questions here in Q&A in future.
Thanks

Why there's no answer, no one uses custom rom? If my topic has a problem say to me what is that.

Okay since you asked, your question literally clashes the rule of xda; never ask what is best
I strongly suggest trying every ROM that you found for locked bootloaders, and decide the one that worked best for you, rather than asking the community's preferences.
For a quick recommendation, use Bagyusz CM11 for locked bootloader if you prefer Cyanogenmod.

If your bootloader is unlockable, I recommend unlocking it (but backup TA partition first). With that, you can enjoy almost anything with less risk of brick. Moreover, shortcut to fix things if your XSP was bricked.
For more ROMs visit this index thread, and see under the category "hijacked ROMs". Have fun!
Anyhow, here's the thread link to the ROM I have mentioned earlier.

Sry u said "with less risk of brick",is it true? I heared After unlocking bl u should be careful because it may brick your phone. So if I install an unistall roms on my lbl phone, it may brick while if I use unlocked bl there won't be any brick?

Please note the word "less"
Actually after unlocking, that is when you can enjoy freedom but still, possible brick is still there. What I meant by "less brick" is that, you can now flash anything on your phone, regardless if that particular something was built for locked bootloaders or unlocked bootloaders.
Compared to locked bootloaders, you must know what you are doing, or else may result in a brick.
I also assume that you know the differences between hard brick and soft brick. This post explains soft brick only.
So if I install an unistall roms on my lbl phone, it may brick while if I use unlocked bl there won't be any brick?

I am also confused with your question Let me answer with my best understanding..
You can't uninstall a ROM on your phone! Well at least, in the terms of such definition.. Second, if you use unlocked bl, possibility of brick is still there. Let's just say brick can happen anytime anywhere. There has been cases of which phones suddenly hard bricked when in fact the user does not do anything on their device! Always prepare for the worse.

To wrap things up, in a VERY general way, UBL gives you less brick risk.

Xperia z1s (c6916) custom roms... Any yet?

First and foremost, let me start off by saying.. I already HAVE used the search function to find threads related to this topic, however, most of them are very outdated, and don't give a straight-up answer to the question. Correct me if I'm wrong, but the Z1S bootloader has a method for unlocking as of now. My question however is this... Are there any Z1S ( Not Z1) Compatible custom roms? Do regular Z1 roms work on the Z1S? and if so, is there a special procedure in making them do so? I just want to know this because I'm most likely gonna unlock my bootloader. and I would like to install a custom rom on my Z1S if possible, but I cannot afford to be taking the risk of bricking my phone if there is virtually no chance of a custom rom working for it.....
So... Any clear answers that can be given would be greatly appreciated. Thanks guys!
As far as I know...
The Z1s has never been unlocked. I have this phone and have had it since the beginning and it hasn't been unlocked. I'm pretty sure after many tries everyone finally gave up.
