Bootloader query - G4 Q&A, Help & Troubleshooting

Hi, I am just wondering is anyone working on an unofficial bootloader unlock? If I knew how, I would be doing it myself but I don't have a clue.
I really loved flashing custom roms on my phone before. And I don't want to void my warranty or anything, even though I have the EU model.
Anyone heard anything?

An unlocked phone may be locked again?

I got an unlocked at&t fuze(touch pro) few days ago. I don't know how it was unlocked. I wonder if it may be locked sim again after upgrading a rom or radio?
Nope man. I think it has to do with the radio or something like that, not the ROM. But to be safe lets hear what more knowledgeable members have to say.
new roms or even radio roms don't relock phones
Fuse locked or unlocked?
How do I confirm that the phone I bought that was suposed to be unlocked actually is?
Thanks
You can install all roms that u want... and if you want to relock your phone, you have to do the work with a separate tool

Will Verizon be able to tell if the bootloader was unlocked at some point?

I have been the owner of several Droid branded devices on Verizon(all Motorola) and when I had a hardware issue, I would just SBF back to stock and return the device. However, when you unlock the bootloader on the Nexus, it says it may void your warranty, which it does on Verizon, but if I relock it again will I be able to get a replacement under warranty? Is there a way they can tell if it was ever unlocked? I would not be returning the device for a bad flash or something, just if the speaker went out or something else hardware related stopped working. Anyone know?
Not sure on the nexus, but on my Droid eris, I had to return it for the trackball several times, and I flashed back to stock and they never said anything

[Q]Unlocking bootloader, questions!

I'll make it short:
1. Since you have to provide your IMEI number on the sonymobile website, i guess that even if you relock your bootloader later, sony will know that you have already void your warranty and you will permanently lose your warranty. Is this correct?
2. Can "locked bootloader" roms be flashed on phone with unlock bootloader. I know it's a silly question but i didn't want to open a new thread for just one question
3. Any benefit of unlocking the bootloader over flashing roms with locked bootloader?
4. Is it worth playing with roms on this device at all, since jelly bean is just around the corner? I know that official firmware is always bad and that the custom ones are modified well. I'm fed up of the lag my phone has, every time i pull my notification bar...i'm on official firmware and i'm using build.prop tweaks but they're not helping much.
SONY Says unlocking Bootloader may void it's warranty.
Well see, this is how it works in my country. Upon unlocking bootloader i loose my warranty. But the warranty for any hardware damage is still valid here. Which means with a unlocked bootloader i will not get warranty if my phone gets bricked by any Custom ROM/MOD try out or Software related issue.
But let's say, the screen isn't working or the speaker isn't working, then i might get a replacement for this type of hardware damage. Only parts replacement.
But yes this may not same for all region. Or may be the SONY service center people here are little too kind
But yes, they can check the bootloader unlocking status easily, if i am not mistaken, cause one of the SONY Forum moderator told me so.
Lastly, Playing with the ROM actually Depends on you, some likes custom ROMS and some like Stock ROM.
But since the JB update is just doorstep ahead, so i would say, you wait for it. Do not unlock it now.

1. Yes they usually check but it depends on your country too. In my country I got my phone's screen replacement done within the warranty after unlocking my boot loader.
2. Yes you can flash any ROM for Xperia S.
3. Main advantage is that you can flash custom kernels ( even ROMs like Cm, slimbean etc.)
4. Absolutely. You can still enjoy official JB even after unlocking your boot loader.

D85020F Bootloader Unlock?

I can't seem to find a yes or no on this, can you bootloader unlock the D85020F?
Thanks!
no one can unlock yet and do you really want to do it and brake your warranty? it's the same as using bumped roms but bumped roms will keep your warranty safe.
What's a warranty? I've long lost my will to deal with manufactures for those lol and I don't think my phone has one I grabbed off eBay and it has two cracks on the housing
Unlock May not have been the best term I guess, is there a way to load custom roms on the g3 if it's been updated to d85020f?

What is the best way to root G4, whilst keeping it "friendly" for warranty claims?!?

Hi, forgive me if this thread isn't in the appropriate section.
I have a bit of rooting experience, haven't done much in a few years though, (knowing that there are now several ways to root devices), and have just picked up the G4.
Now I'd like to root the G4, but keep the stock rom, (6.0) and mainly will be just running xposed to edit and muck around with LG's ugly skin. I'd still like to be able to receive OTA updates, (even if the OTA update may remove my root,) as well as hopefully still be fine if I needed to return the device under warren.
I've been reading around and apparently you must unlock the bootloader in order to root for Marshmallow? If i were to still do this, could I keep the stock recovery at least, or if not, would I be able to easily revert to stock with a stock recovery and relock the bootloader?
Apologies for my ignorance, just trying to figure out if I should really be rooting or just chuck on Nova launcher and be happy with LG's offerings. Cheers
Keep it on a stock rom and if yoi have a carrier varient then try to not change the boot logo lol idk just a guess.

Yes to reflashing stock rom
Yes to relocking the bootloader
So you are clear to make whatever modifications you want, you can always revert safely.

Once your bootloader is unlocked, you cannot relock it. Your device will always show a message saying "Bootloader unlocked" after turned on. Warranty is likely to be declined then. BTW: You have to get your unlock.bin file from lg, agreeing to void your warranty. So, even if you smash your screen and they cannot see the message, lg knows it is out of warranty.

Since when do you have to get the unlock.bin? We unlock from fastboot. Have you confirmed by trying to relock from fastboot? I read otherwise from another thread.
Furthermore, a quick search around indicates people who have unlocked and rooted have had their warranty honored despite software changes.

Unlock from fastboot is only possible after flashing said unlock.bin file, which can only be obtained by lg and is unique for each device. Furthermore, I had an unlocked, bootlooping h815 and lg refused warranty to me (in Germany). Got my phone replaced by my vendor on eu law which only applies if the defect strikes in the first six months.
So, while some people are lucky to have their phone repaired despite an unlocked bootloader, I'm really happy for them, but lg is not bound to repair it on warranty

Ah I see. You have a h815. I have a h811. Our process differs there.
Hmmm, thanks for the info guys. Its not from a carrier, i bought it outright. Seems like i might just have to keep it stock, its not too bad as is, guess ill just have to live with it. Thanks for the help though.

At least you can root with locked bootloader
Not under marshmallow
You can do none of things you listed keeping it stock. First of all google change policy and in marshmallow you need to flash modified boot.img in order to flash custom recovery and/or to root it. As you know the bootloader has to be unlocked but there is no way to relock it. So sorry, but impossible.
People need to understand a simple thing.
You either mod your device and lose warranty or you keep it stock.
It's that simple. People worried about warranties and ota updates are on the wrong site.
