Hey guys! I have recently unlocked the bootloader for my LG G4 but I don't like how when I boot, it shows that the bootloader is unlocked in the top left hand side because now the phone looks a lot less professional.
[I would attach a picture of what I mean if you don't get what I'm trying to say but since I'm a new member, it won't allow me]
Yeah, I've been wondering the same thing. What I would like even more is if there was a way to change the boot screen completely.
Can't hide it :good:
this guy claims doing it try and report my model isnt unlocked so i cant try
otherwise it can't (no one got it yet)
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.
I bought a Moto Z Play off of Swappa and it's arriving on Tuesday. I wanted to double check that the bootloader's locked to make sure that it wasn't loaded with any kind of keylogging software. The seller had photos of it still in the original packaging, but I'm paranoid, so I just wanted to make sure. If I do the volume down + power button method to go into fastboot, how will I know if the bootloader's unlocked? I've seen a few photos of the fastboot screen, and none of them seemed like they had that info.
If the bootloader ist unlocked you should see a warning screen for 5 seconds immediatly after starting the phone.
Edit: i found this in the OnePlus Forum:
"You can also type this command : fastboot oem device-info
if you see the word : true instead o false near the result, that means you're phone is or have been unlocked"
the easyest way is to see if you getting 5 second warning on boot
Anyone else know where the info would be on the fastboot screen?

Where do I use that command? On the fastboot screen? I know there's a dial code I can use to check the bootloader, but I was hoping to see it before I logged into the phone.

Any idea what that warning looks like? Is it just the little unlocked lock icon?
You cant miss it. It shows up as the first screen your device displays immediatly after starting it. It will say something like "The bootloader has been unlocked. This device can not be trusted" for 5 seconds and then proceed the normal startup procedure. If you miss it then your bootloader is locked.

So, if the bootloader's locked, then phone should be safe for use, right? Or is there anything else the seller might've done to tamper with it?
Even if the bootloader is unlocked it could be safe.

But if the bootloader is locked, does that mean it's definitely safe? Anything else I could do to protect myself?

Basically what separates a locked bootloader and an unlocked bootloader is the ability to alter the partitions of the phone. A phone with an unlocked bootloader could probably be reflashed in a way to skip the Google sign in lock after a "reset" and be sold off if it were stolen. If you have a locked bootloader and a password on the device, all that could be done is a wipe through stock recovery and be prompt by Google to sign in with the previous account. In terms of OS security patches, your basically helpless until the device manufacturer feels like maintaining the device. Apparently Android O is supposed to fix that with project treble where Google adds an extra API layer on the kernel level.

Did you miss my opening post? I said I'm buying a new phone from an independent seller. I wanted to know if there's any way to check if they installed malware of any kind that might keylog me.

I'd check the indication of an unlocked bootloader as others previously mentioned, look at what's prompted upon booting up the phone. If it was unlocked, the message is as clear as day that tells you it's unlocked. If they tried to cover that up you'd still see part of the message like "N/A" or "bad key" within the logo. That indication right there alone is suspicious. Should you contact the seller or reflash the stock firmware yourself, you should be wary about what's already installed on the device.
If you don't see any indication of an unlocked bootloader, then I'd still wipe it through stock recovery and run an app that checks signature verifications and heuristics of malicious apps (Malwarebytes or some other antivirus app).
I forgot to mention the logos that are SUPPOSED to show on the device depending on what Android version it's on.
For marshmallow, you should see the white logo I've posted in attachments along with the indication I marked where you'll see text from the bootloader telling you that's unlocked if the seller tried to cover it up.
For nougat, the one with the aqua colored background and the indication I marked where the cover up text should be.
If there's nothing and the logo is "natural" looking and you don't see a message before the logo then your bootloader is probably locked.
Edit: sorry the indication for the nougat is slightly lower than where it needs to be. Should be on the same level as the marshmallow one.

I don't think there'll be anything installed (besides the possibility of malware). It's supposed to be a brand new, unopened phone that's still in the original packaging. It'd be too suspicious if there are apps already installed (besides bloatware that's on most phones).
Hello all,
I'm thinking of buying a bricked Huawei Watch and reflashing it.
Seller says it got bricked during an update and can't start but it can enter the fastboot menu.
My question is- is there a chance it can't be unbricked or it can be fixed for sure? I have 0 experience with smartwatches so I'd appreciate any information on the subject
Anyone?
In general, if you can fastboot/bootloader it you can flash a recovery, and with a recovery you can ADB sideload a ROM.
Obviously I have no way of knowing what you might get buying a "bricked" one...so don't take that as any kind of guarantee.

If the seller is being honest and the only thing that went wrong was a bad OTA, you should be able to resurrect it fairly easily.
Actually, now that I think about it, the bootloader on that watch is still locked. Have the seller unlock it and show proof that it worked. If the bootloader cannot be unlocked for whatever reason, the watch will be significantly harder, if not impossible, to resurrect.

If someone is selling a failed OTA as a bricked device, I doubt they know HOW to unlock a bootloader.

You're assuming that the seller isn't lying. If the seller knows how to put the thing into bootloader mode, and he does, I think it's a pretty good bet that he also knows how to unlock and lock the bootloader.
Honestly, I don't buy the whole failed OTA story. I think the dude messed around with the watch without knowing what he was doing, bricked it, and is now trying to minimize his losses.

Fair points. I think the lesson here is ALWAYS be cautious of sold as bricked, obviously.
But I still feel the point stands that IF it can get to bootloader it is generally recoverable barring actual hardware failure.

You're probably right. The only snag I can possibly think of would be if for some reason it could not wipe the device. Unlocking the bootloader triggers a wipe, and if the wipe doesn't happen the unlock might not happen. Also, if something is wrong with the USB connection, bootloader unlock might be impossible for that reason.
Hi all,
So my father bought about a year ago his galaxy a50 in a new sealed box from unknown reseller, and recently the phone got locked by the network operator due to unpaid tax invoice for this device. It seems like the guy purchased it and only paid the first rate, and then resold it to my father for a full price. The phone when turned on displays a huge notification on the lock screen menu and does not allow me to do anything. Tried hard reset, didnt help. Anyway, I also tried to flash a linearge os on that, but it threw an error because the OEM unlocking option is not ticked (However, I managed to unlock bootloader before the device went down).
And my question is, is there any way i can flash any custom rom to get rid of the blockade without unlocking OEM? or should i throw the device away?
Thanks for any feedback !

The hard way easier said than done :
0. Factory reset your phone
1. Find a smashed A50 cheap
2. Replace motherboard (open up adhesive with heat gun)
3. Put your motherboard into the smashed one
4. Sell the reassembled smashed one on eBay for parts only
5. Profit
yeah.. actually I dont have enough experience to do it myself, I guess I'll just sell it as it is
Can you reflash stock ROM on Odin as an final desperate attempt of re enable unlock bootloader?
(Won't elaborate here, don't have time, you may search)
Stock ROM is from samfw.com
Actually i failed flashing TWRP on it, coulnt even get to the moment of flashing the rom

It still can boot, but when i set it up with the minimum permissions (no google account , no wifi. anything) the blockade still comes up straight away
