Rooting and Warranty void? - LG Optimus 4X HD

Hi
i just bought my phone month ago and i really want to root the device and use different roms
i observed that many here did that
does really rooting void the warranty and if is true ? can i do unroot for warranty
also does rooting has a relation to battery life impovement or it is the roms
my battery life is not good
i even bought an extendable 4300 battery from china and still bad it is just "the 4300 one " stood for 23h with light use
thanks in advance
NB : sorry for the bad english

Rooting can void it, but is undetectable if you reinstall the firmware which will remove it. Unlocking the bootloader to install ROM/kernel however cannot be reversed, but is undetectable if you revert to ICS. Rooting itself will do nothing for battery its the changes you make with this access, whether that be a new ROM, kernel, or simpler things like changing clock speeds with tegra overclock or similar

What does it mean that unlocking bootloader can be undectable after changing ROM to ICS?

Because the ICS ROM was never made for bootloader unlock, so it will be locked in ICS, but if you flash JB again it will already be unlocked

So, after unlocking bootloader and (in case of some damage) changing ROM to ICS mean I can still use my varranty? Or not?

It depends. LG can still tell if you have unlocked, unless you really think they are that stupid.

Yep, all they would have to do is update it to JB or even just look in sys/firmware/fuse/odm_reserved for changes. If they care they will find out

I have yet to find out how it would be possible to damage a device while using custom roms or rooting it. Unless someone is really stupid to do something dumb, there is no risk whatsoever.
Once you root it though, I believe its over with the warranty.

It all depends where you are. The company cannot, certainly under UK consumer law, refuse to fix a hardware fault just because you have rooted your phone or unlocked the bootloader. They can, however, if they can show that you have caused the damage by over-clocking the CPU or playing around with the voltage settings.

About bootloader - there is somewhere the app which can change the fuses and relock it

They could still see the difference. Fuses are written only once, so if the fuse is not the same as the original code well...
If it looks anything like mine:

Then there's no hope

I think they don't even checking that.. :d

Cmon you would have to be very unlucky to have warranty refused when something breaks and you want to have it repaired just use relock unlock method, seriously doubt they will be checking fuses, and even if they have checked would they refuse repair

Flash it to latest imei firmware and be nerd infront of them i doubt they will check anything else.

LG Italy has officially stated that it will repair under warranty LG smartphones rooted and with custom ROM installed, no questions asked.
I'm not able to tell what other LG subsidiaries will do in other, different, countries.
Maybe you should ask.

Thanks for that. Interesting that it was over two years ago, and they specifically mention "rooting", no reference to unlocking bootloaders. It may be worth you asking the question of them to find out what their stance is now.

rooting and installation of alternate firmware, which you can't get without unlocking bootloader. still, this is old, and i'd really really like to know what their stance is today

Untrue. You can install alternate firmware - we had that ability on the 4X without an unlocked bootloader. What you can't do is install a custom kernel.
Unless they specifically state that they will support warranty claims with an unlocked bootloader then this is worthless anyway.

After an update every OS is unrootable, or at least should be for a certain time, since no provider/producer wants his product to be rooted.
It's hard for them to prove, that it's been rooted, but you can destroy the device with it, by e.g. Overclocking the CPU. They have to repair it on warranty,--> the patch root methods in order to keep users from rooting, but it never lasts long
So some providers lock it harder and some only spend 2 secs on patching

It's not a problem. It's a feature. Nobody should release rootable phones. That means there are serious vulnerabilities in their software, exploitable by malware.
What they should do is to have an option to have adb shells running as root. Most users won't know what it is anyway and won't be able to mess up their phones, but for those who know, installing Superuser.apk would be trivial. Everyone wins.

Rooting this device? Is there any work around

Hi
Like me, many of us are waiting for the pre order to come on 28th or soon after. Would love to root as soon as it is unboxed.
Is there any work around for rooting this device?

Guys in Development section already got kernel sources - so it might come faster than we think - but surely not as soon as it is unboxed. You'll probaly have to wait at least few days.

Rooting is easy if any devs got a device already they could make one in less than 10minutes. Even they could make one now given the stock ROMs available now in dev section. What we really need to have now is how to relock the bootloader.

So since this phone is due for release is it a known fact that the bootloader is unlocked & also what would be achieved or the benefits of relocking the bootloader. Can't imagine why to relock coz despite best efforts by top developers over a year, my current phone's bootloader is totally hack proof (not impossible but improbable)

It's features.
With relock bootloader you could do OTA, Bravia Engine, download music info and stuffs. Plus maybe get your warranty back.
I can't imagine seeing lots of people buy the Xperia Z then unlock it then weeks after sony announces 1st batch of the devices have some major bug and you can't return it back because you void your warranty because you unlocked your bootloader.

There was a "trick" where people fried their radios ( wifi, BT etc ) with a microwave to claim warranty - since those are on mb itself, service usually replaces the whole board. In theory there is no way to tell that your radios were damaged on purpose by a microwave - this way some tried to claim warranty saying their radios "just stopped working". Some claim it worked, others it didn't - i myself believe it to be utter gar.... if you put your phone into microwave, you're gonna have a bad time

Hmm I think that ain't gonna work since if you ever fried a radio sony can still check if whether the bootloader is locked or unlocked. Better fry the whole device instead :laugh:
Well I just mentioned what I read & yeah I think it's for less than 10 secs @ lowest wattage But hmm yeah I didn't know that it is yet possible to check if BL was unlocked.

Uhm yeah correct with that one but I was talking about rooting on unlocked bootloaders
rooting it while it's locked is an exploit or security flaw so yeah it's hard to do.
Regarding relocking bootloader no idea how to do since my last sony device was unlocked using testpoint and there's no way of relocking it yet at that time.
What I'm interested in at this point is anything with the drm keys. I want that to stay even when the device is unlocked. Do you know by chance where is it stored anyways? Is it on one of the partitions inside the phone or is there a seperate chipset where it is isolately stored? Or is it something like a firmware embedded to a chipset?

[Q] Bricked Razr I

Hello to all and sorry for approximate English!!!
I have bricked my razr I after to have used RSD lite and at the time of restarting that this has never restarted!!!
Now I have a green diode which ignites during a few seconds then 2 rumble and it off.
Thus RSD lite does not re-know it any more, once connected on a PC, I just have the right(law) for the green led lit(switched on) longer!!!!
And sometimes my PC tries to install a driver MEdfield which it never finds!!!
It can it be a solution?
Have you other solution ?
did u downgrade from JB to ICS with rsd lite? Than your Razr i is one giant brick. At the moment there is no solution for that.
And if u didnt do that, i am sorry, i dont know the solution.

Effectively, I am pass of ICS then JB then ICS then JB with no problem at all, my problem has place during one update with JB under RSD LITE That this made these 11 stages normally then at the time of restarted the such has never restarted!!
At the material level the solution it is what to change the motherboard mother of the such and if yes how many cost?

I did the same brick, with unlocked bootloader. Then i sent it to the warranty and said that an cable update failed. After 10 days, they said it was totally dead, then they gave me a totally new Razr i, with the box and everything.
Since the werent able to make it run, they didn't know the bootloader was unlocked.

They should make something that we could access remotely to update this. Like, c'mon, we are in 2018 they don't our phone in their hands to update it.
So is this done on the hardware level so that it sticks for factory resets and custom ROMs? You know, like official LineageOS 15.1 released today? :fingers-crossed:
And I noticed a few others mentioning locked bootloaders... I don't care if I have to wipe and relock it to have it serviced but will I still get L1 if I unlock and TWRP it again?

I dont think the "update" would surfive a full wipe as there are no extra partitions/chips to write to that we ourselfs cannot. If i'm wrong please do tell..

This update will survive wipes, and can surely be used for OOS based ROMs, OnePlus told me that rooting, unlocking the bootloader will not break the update again and that it is going to stick when on custom ROMs (they haven't guaranteed it tho). The reason why we, users cannot do the update ourselves, is because of Googles requirements - the executing PC must be authenticated to to generate special keys, which are unique to each and every device. It is inconvenient, but it's the only way OP can execute the update.
