yes. you can unlock it with a simple phrase in fastboot.. "fastboot oem unlock", and you can lock the bootloader in fastboot too using.. "fastboot oem lock". there are apps that lock the bootloader too. you can also flash the stock img via fastboot.

if i lock it back is it possible to lg know i ever unlocked? in some phones like the xperias there is a kind of track.... thanks for the fast answer

this isnt because of lg, its because of google, its one thing that makes every nexus great, the option to easily unlock(and lock) the bootloaders. if its unlocked, when booting up, on the google splash screen, youll see a unlocked padlock on the bottom of the screen, and the bootloader will say unlocked. if there is a hardware issue, google will also except rooted/unlocked bootloader phones for exchange/repair. but thats if its bought through the play store
if you go back to the factory img, and keep the bootloader locked, they will not know.

no, the other stores would have their own policies. and probably be more strict than google itself..
about best roms/kernel, you really have to try them out. everyone has differing needs, and every device will react differently to them, especially kernels. try out a bunch, thats the only way that you will find your perfect setup. i use the rasbean rom with the trinity kernel, for me its a perfect combo. but, the developer of rasbean is a close friend, and im the only tester(before release) of the trinity kernel. and i dont want to blind you with my setup only, as there are many good roms/kernels here.
about battery life.. its your signal, your setup, and how you use the device that mostly decides your battery life. dont enable anything if youre not going to use it(i dont use to many notifications, since i dont have the need. id rather check myself). and there is a good app called greenify that i recommend, itll help with controlling badly behaving apps, they too can lower your battery life.

He asked if we relocked the boot loader, will LG ever know that it was unlocked earlier? I have the same question too.

Who Has an Unlocked Bootloader?

Hey guys,
With All this Warranty talk, the people who unlocked your bootloader. Do you regret it? Was the warranty worth sacrificing for custom roms? I want to unlock it but at the same time I keep getting these paranoid thoughts that I'm gonna need the warranty later on. WTF. Any help?
You can install custom roms without unlock bootloader. I have evil nxsense rom installed in my N1 without unlock my bootloader.

HTC honors the warranty even with the bootloader unlocked; I can't say that I've needed to make a claim myself, but that's the consensus from majority of members on this board. So, my advice is just go for it.
I had the same doubts as you, but you won't regret it

Agree with this. Although I've never had to make a claim either.
I unlocked mine as soon as I pulled it from the box back in January 2010. I have had no regrets about it at all. I have never needed warranty service, though I wouldn't hesitate to call HTC for a hardware related issue. If something went horribly wrong with a ROM flash or a radio upgrade, that would be my own fault and I would look into buying a new phone. But I wouldn't try to BS HTC to make them pay for my screw-up.

I have made two claims with my unlocked bootloader. Each has been hassle free and quick. Oh, and cost me nothing.
First, a few months ago for dust under the screen, repaired and sent back in 4 days.
Second, which was last week for power button issues. They received, repaired, and shipped back in one day. I got it back the next.
HTC is quietly brilliant.
thanks guys! i may actually unlock the baseband than.
is unlocking the baseband more beneficial than just doing a root without unlocking?
btw, so you guys think its better to safer to send it in and get it repaired if you have a unlocked baseband than the riskier "swap" (when they send u a new one and you send your old one in) method?

hey, did they send it back to you with a locked bootloader?
First time they relocked it.
Second time, they left it unlocked.
ROOT is fine

I don't see any point in unlocking boot loader while you can root the phone and do whatever you want. the only thing you can't directly do is to flash a partition usion bootloader commands but you still can do it if you use "flash_img" command in ClockworkMod Recovery (on the adb shell). I install different roms and I am on CM7 now.
I unlocked mine without wanting to. I flashed modaco rom and it just unlocked my boot loader. but there is supposed to be a way of locking it again. it's somewhere on xda...

Yeah, I like posters that don't know what they post.
1) No ROM can unlock the bootloader. User has to do it and the system has to ask for permission.
2) Once unlocked, it can't be locked, only by HTC.
To the OP: I've unlocked my bootloader long before "non-unlocking" way has been found. Never cared for it since, didn't need the warranty, and it's going to expire soon anyway.
Yes mine unlocked, and I have no reason to regret it, as my phone is a freak that can be locked again.
Worth doing in my opinion, and even if I couldn't lock it again, I still wouldn't regret it.

Mine is locked, but there are 2 goods reasons to unlock the bootloader:
1. Once the bootloader is unlocked, you always have a rooted phone. The next ota won't relock it.
2. You have more options to fix a potentially bricked phone.
I'm thinking about doing it for these reasons, plus it seems like HTC still honour the warranty.

I unlocked my bootloader because the warranty was gone anyway. Put the nexus into the washing mashine . Somehow it survived (Bluetooth, radio and camera gone). It actually was pretty tough. after about 10minutes in the mashine (60°C) the screen was still having fun inside the mashine.

1. Well, if you wanna update ota, you don't have reason to root your phone in the first place.
2. what more options exactly you have? simple, do not mess with HBOOT and Recovery partitions, and ur safe.
My opinion, use oneclickroot and don't risk it, cause HTC support behave deferentially now!

Nope, you're pretty screwed. When unlocking the bootloader, the phone tells you that your warranty is now void.
The nexus S has a oem bootloader unlock. In other words, samsung will not hold the fact that bootloader is unlocked against you. You do need to get rid of miui and get back to stock. There is a thread showing how to do this and provides the files you need. I'll see if I can find it for you.

I said that because I was screwed over by Samsung.
I just use cwm to flash the latest ota rom then locked the bootloader and reboot.
no issues from samsung regarding voided warranty. Perhaps you had sent it in with the bootloader unlocked?
Just use rom managers stock 2.3.3 and flash it... then lock bootloader by the instructions provided a post up
Just a heads up... same thing happened to a guy and he sent it in.for a speaker that wasn't working ... he waited over a month to get his phone back rather then them sending him a new one or refurbished

good luck! make sure the bootloader says locked, and there is no super user app and no custom recovery!!!
I used Stock Odin image that will restore everything rom, recovery...ect then just lock bootloader. Funny thing is i sent mine back all stock and bootloader locked few months ago and got back with bootloader unlocked.

Relocking the Bootloader

Hey guys!
I just bought a Nexus 4 a couple days ago... you can imagine my desire to unlock the bootloader and root my phone, I think...
I do have one concern, though. My last phone was HTC One X. I unlocked it, of course, but relocking the bootloader kinda got me in trouble. When bootloader showed up on the screen it stated "RELOCKED" thus my warranty was void. I would like to know if such thing could happen with my Nexus4 device, since I wouldn't want to loose my 2-year warranty in case I decide to sell it somewhere along the way.
Cheers!

people said no(they said that if u do oem lock it would just lock normally) with nexus 4, i cant test because i cant flash new bootloader(my phone dont allow new bootloader since i flashed the one for lg og).
Edit, talked with my friend, and yea if u do oem relock it get back to factory normal, any1 will see what u did there(unless u have installed root or custom boot/recovery).

my friend said that the OTA updates require locked bootloader, then I would like to lock it again ...
and how this under warranty, also wanted to make everything from factory
Your friend is wrong. You don't need locked bootloader to get OTA.
To get OTA update, you need stock rom and stock recovery, locked or unlocked doesn't matter.
You can also flash the factory stock image without wiping your data (see link in my signature).
If you have root you can use this app to lock and unlock your bootloader: https://play.google.com/store/apps/details?id=net.segv11.bootunlocker

I guess something is up with your phone physical memory, but it doesn't matter, it really should not affect your warrenty (but the custom rom and recoveries will). Makes zero different to OTA updates either.

Honestly, I don't think they care if you have root either, but that's base on other user feedbacks. It seems LG warrenty is picky about other things and not very good from the feedbacks from what I read actually, but I haven't had first hand experience. But people have sent in rooted devices for repair.
I think just have factory image and stock recovery and stock kernel.
Solution !

Simple question

Hi guys.
I have a Zenfone 5 A501CG with Lollipop (3.24.40.87_20151222_34) and I rooted the phone.
There are some things which I would like to improve like better battery, better gps signal, louder volume on the speaker and get signal back after I lost it (eg.: I'm in a zone with bad coberture and I lost the signal and then I go to a good spot. To get the signal back I need to reboot my phone or I will stay like airplane mode).
So I'm thinking to install a CFW. I still have warranty of phone (5 months left) but if I have any problems I can get it to stock right?
My question is: what's the best CFW for my phone and how to install it?
Thanks for your attention.
Best regards
if you wanna use cfw, you must unlock bootloader (ubl)
and if you ubl your z5, you phone may caused random freeze screen
my solution is, if you wanna use the best ROM so far, use kitkat 2.22.40.540
or downgrade to 3.24.40.60
it is most stable of the L stable..
it will solve your signal problem..
also you can root & install xposed..
Greenify & auto starts will help you with better battery life..
how to downgrade ? ?
Search this forum..
& if you like KK. 54 is the best

so far there's still no solution of this freezing problem
some people say it's motherboard driver problem
some people say it's dnx and ifwi problem
i really want have dt2w feature but to do that i must ubl my phone first
i have tried every possible way to ubl without freezing but still can't do
so i just back to kitkat because i think kitkat is still the best and most stable fw for zenfone 5

no this is a bootloader fault and nobody can fix this but you can try it and when you have freez lock bootlodaer and go baCK TO STOCK not erveryone have frezz
I think I will keep the FW I have and wait. Maybe in a near future the booloader works flawless. Thanks for your help

Just make sure you relock bootloader corectly
If you have relock your bootloader, go to bootloader n check your ifwi, if your ifwi isn't 59.a1 your z5 won't freeze anymore

no.. there will be no solution..
we have known about this issue for almost 2yrs now..
till now there is no solution..
People have tried on their own.. without any support from asus.. but no results..
and as far as I know asus has not offered any solution nor support..
but funny thing is not everyone is affected by this..
you will have to unlock your bootloader to check if you are one of the LUCKY ones..
you can always relock if you are one of us..
yes I am among the unlucky ones..

random freezing & phone brick are two different things..
& yes you can return to stock anytime you want..
before doing anything thing backup your data..
while on stock you will have to use an app to backup..
I use titanium Backup pro..
of course I have a rooted phone..
I suggest
1. root your phone
2. do a thorough backup..
3. saperately.. backup your contacts, SMS, call log..
4. move all backups to memory card..
5. move all your data from internal to external memory..
6. unlock your bootloader..
7. use your phone for 2 - 3 days..
if you have random freezing..
lock your bootloader.. & decide your next move..
for root, backup, bootloader unlock search XDA.. everything is already there..
