Question, I am debating to root my Optimus G Pro. Does the G Pro have the Efuse bootloader? I heard if you alter it may void the warranty. Is this true?
Of u alter the stock software in any way on any phone it voids the warranty. Rooting, bootloader unlock, modding, etc on any phone from any OEM voids the warranty. Period. I'm not sure if its specifically efuse technology but running unsigned software did hard brick the device. Fortunately thanx to djrbliss a workaround (Loki) was ported and we can flash ROMs with no issue. It has since been discovered that lg does log su commands being ran this can be fixed by flashing a stock rom using lgflashtools. This is a great phone made better by the aosp ROMs and probably the best deal out there right now considering cost vs use. Hope this helps.

I just got my N7 today, so I don't want to void my warranty immediately. Is it possible to root without unlocking to bootloader (like eg the tf300 could be) or can the bootloader be locked (not relocked)?

So not yet.... even on the HTC one we got an exploit, at least until the update to 4.2.2 came along. I guess I will wait a bit to get a feeling of the device
Btw, can Asus see if the device was unlocked in the past?
Not sure if they track our serial numbers this time around. For their Transformer devices, there are an unlock tool apk directly from Asus, so I KNOW that they are tracking those....
But Google embraces development, which I think is the reason why the bootloader is so darn easy to unlock. Keep in mind, I'm coming from HTC devices, and I'm not used to these one line commands to unlock. We had to jump through hoops, flaming with fire.

[SIZE=+1]There seems to be a lot of confusion and misunderstanding circling the forums with regards to Knox and the 4.3 OTA.
This is an attempt to clear things up[/SIZE]
UPDATE: It seems that people can find this thread, but are unable to actually READ the information presented. The most important note here is that if you are on 4.3 firmware, you can flash ANY rom you like. No, you are not tied down or locked into stock only or 4.3 roms only. AOSP roms will work fine as well. Now scroll down and READ EVERYTHING IN THIS FIRST POST.
What is Knox? Knox is both a firmware and a software component. The OS has Knox apps, and the MK3 bootloader has a Knox component too. Having Knox apps does not necessarily mean you have the Knox bootloader, or vice-versa.
How does Knox work? Because Knox is both in the OS (apps) and in the firmware (bootloader) it works in two ways. The OS components prevent attempts to obtain root access and make rooting with these Knox apps a pain in the butt. Fortunately they can be removed. In the firmware component (bootloader), Knox works to prevent the flashing of custom kernels and recoveries. If you flash a custom rom or custom recovery WHILE on the Knox bootloader, your Knox flag will be tripped and your Warranty Bit will go from 0x0 to 0x1. The Knox bootloader cannot be downgraded to, say, the MD4 bootloader because of special protections built into it. If you attempt to downgrade it, your phone will instantly brick.
Can I get root on the Knox-enabled update? Yes. For those of us who DID NOT take the official OTA and DO NOT have the Knox bootloader, we can get root on 4.3 by injecting it and removing the Knox apps. For those WITH the Knox bootloader, you will need to wait until a full stock MK3 tar is available, which we can then use to make an Odin-flashable MK3 stock rom with root injected using the de-la-vega root method.
Can I downgrade while on 4.3? You can flash roms no matter what Android version they are. That is perfectly fine. But you cannot downgrade the bootloader if you have the Knox bootloader, or else it will cause your bootloader to become corrupted and give you a fancy paperweight. Again, for those who DO NOT have the Knox bootloader, you needn't worry about this/downgrading firmware since the Knox bootloader is what prevents you from doing this. Downgrading your bootloader includes: attempting to flash full stock tar of software versions < MK3, etc.
How can I tell if I've got the Knox bootloader?
Boot into download mode (through custom reboot menu, or by powering off then holding Power+Home+VolumeDown and then VolUp when prompted). If you see a line that starts with the following, then you've got the Knox bootloader. I will insert a picture showing how it actually looks soon

No way to remove bootloader Knox ATM.
I've seen several posts mention "tripping KNOX" or "voiding KNOX." What does that mean, exactly, regarding rooting a phone? Does it just mean it voids the warranty if you need to get support from Samsung/Sprint? Or are there other adverse effects?
Mostly just a visible warranty void.
Samsung bought crapple disease. So sad, but its my excuse to buy a nexus.

As said above, a voided Knox is mostly just a highly visible warranty void. Your local Sprint store may or may not care, or the specific Samsung rep that you deal with may not care, but it's easier just to not have to deal with it to begin with.
Does this mean there is already a touchwiz 4.3 ROM we can flash or do we still have to wait?
Sent from my SPH-L710 using Tapatalk
The biggest thing here is the fact that there is no full tar file to restore. So even if you do not care about knox or warranty. If something goes wrong with a flash or anything else you can't use an older tar file let's say MD4 or LJ7 or anything because you will end up with a brick. There is nothing to use to ODIN restore your device. Once you go 4.3 with Knox you have to stay 4.3 and even if you wanted to stay 4.3 and wanted to restore that there is no tar file at this time.
Have a great day!
I have a question I think we talked a bit about the problems the knox bootloader brings into the system. My question is the opposite what does it fix / change?
Im thinking along the lines of somebody modding the update so an old bootloader would be with the new rom would that be an issue? I think i remember hearing something about wifi being the problem but any clarification would be nice.

Right now, wifi is broken with the old bootloader and 4.3 rom...happened on the other devices too (tmo s3 and sprint s4)
But there is a fix: flash at&t kernel. But it messes up screen rotation. So i'm trying to come up with another fix that will let wifi turn on properly and let screen rotation work properly too
You = rock. Or some other awesome thing.

So is this Knox a Sprint thing, or a Samsung thing?
I can understand the reasoning for Knox(money) but, dang, I guess it's a dog eat dog world out there.
This doesn't affect CyanogenMod does it? I'm scared...
edit... I remember reading about a brick api or command, I never executed it, sounds nasty, is this what they use to brick peoples phones if they try to "hack" it?

This would be a we-can't-update-the-bootloader thing lol. And we can't do that because it has Knox, which is Samsung's doing
This shouldn't affect any AOSP roms because it uses a different kernel and builds its own WiFi libs

From what I've read Knox is Samsung's attempt to provide strong security to their phones for the enterprise customers. As you can imagine, allowing system level access to files can be used to get around a lot of security measures that IT people would like to enforce in their client's devices. It makes sense at the enterprise level, but it's a pain for anyone who want's to mod their phone.
So I think the answer to your question is, unless you are using your phone in a locked down corporate environment then there really is no advantage to Knox. Too bad it can't be turned off, at least not officially.
does the g3 have any sort of tamper flag like knox on samsung , which voids warranty when rooting?

Pretty sure any sort of rooting technically voids the warranty. That's what an ODIN reflash is for.

Any device with ics or better can run Knox software and Samsung pushed it back to Google who will put it in Android L
Don't feel like having a device with Knox well the new iPhone may not have Knox

so the lg G3 has any sort of tamper flag implemented?
Well, I used towelroot to root the G3. It's pretty non-intrusive and very simple to use. No reboots required. Just install the APK and click a button.
Your bootloader stays intact and so does the stock recovery. If a simple root is all you want, try towelroot. You just need a factory reset to remove root.
And yes.. the S5 users are using it to root their devices without tampering the Knox bit. Based on this info, I would say it's pretty safe
No way to unroot towelrooted device without hard reset?

Is the factory reset enough to make the phone accept OTA's? I can't see why it wouldn't be (unless there is a tampered flag) however some people on here have said refreshing stock rom is the only way to do it.

I used towel root on my LG G Pro 2 to change my build prop so that I could install and run skygo. I performed a full unroot with supersSU Pro and surprisingly found that this did not satisfy skygo and it still flagged up as rooted (superSU Pro has always worked for me previously with other root processes).
I repeated the root process and I found some additional towel root files in system xbin which I removed then ran unroot with supersSU Pro and was then able to run skygo successfully.
I hope this is relevant to the g3 as I intend to buy a 32gb version but would like to have skygo on this. For the first time in my life, I am not charging in head first. I am holding back on my purchase and reading everything about it first.
Not sure I can keep this up for much longer though.
Good to know where to look.
Thanks for the info:good:

Hi everyone!
I've been debating over whether I should unlock the bootloader or not. Because I really haven't made up my mind, I came here looking for some feedback.
Right now I 'm running LP 5.1.1 rooted and with xposed installed. The phone is really fluid, no lagging problems as far as I can see.
The main thing keeping me from unlocking is the bootloop issue (my G4 is from the 505 series). I know some users managed to have repairs under warranty, but I contacted LG Portugal and they basically said that there is a real possibility they won't fix my phone if something happens.
If I unlocked, I would definitely install some stock-based rom, as I don't want to loose the awesomeness that is the G4's stock camera experience. With my current setup I'm able to squeeze 3/3:30h SOT almost everyday.
So, with all that in mind, is it really worth unlocking the bootloader and loosing the warranty just to basically update from LP to MM and possibly have a custom kernel? Is MM that good of an upgrade?
Thanks

dont unlock it.
1.i think that with this bootloop issue around you would want the warranty to stay as long as it can even if they tell you that they wont fix it....and i find it kind of hard to believe because what the warranty is for beside that? :/.
2.the differences 5.1 to 6.0 are only minor and i must say that my battery life is the same ( i dont have root, i use stock MM)
Thanks @xzfzx.
I am screwing around with my VS985 G3 but I have random / phantom screen touches and the top 20% of the screen doesn't register touches properly anymore. I just tried doing a factory reset thinking it might be software problem but it still seems to have the same issues (23C) when hard reset. Soooo, I am considering moving up to the G4, but the main thing I don't want to lose is the unlimited hotspot data since I still have the old unlimited plan and use it frequently as a hotspot for devices in the house. So I needed root to install the hotspot mod and want to make sure I can root any G4 I wind up purchasing.
What are the requirements for a rootable G4? Are there firmware versions that are not downgradable via kdz/tot method? Should I ask before purchase for a device that is on firmware XX or lower to ensure downgrade capability?
From what I understand the G4 is the end of the line for unlocked bootloader devices, correct? I don't have any other internet options at my location so the unlimited data through VZW is critical to me at this point thus I can't live w/out the root access on my device.
Any recommendations or help is appreciated!
Cheers,
-Scott
I was hoping someone could just advise about firmware level that allows downgrade? I am reading up on the G4 but not sure yet what version of firmware or > prevents downgrades. My preference would be to buy a phone I can downgrade to 13B and run a custom ROM. Now looking more closely at the "android development" forum for G4 I see there really aren't any custom ROMS for G4. Is this because G4 is a locked bootloader?
In the meantime I determined my G3 screen really does have a problem so ordered a replacement, so I'll try that since I was able to downgrade that to 10B and so should be able to keep that running with custom ROM's until I decide what I want to do to upgrade. I do see that hotspot mod is actually available on G4 with 13B root. I'm just concerned about buying a G4 which won't allow downgrade so hoping to get an answer about that.
The verizon G4 has a locked bootloader so no custom ROMs here, but you can certainly root. I just recently downgraded from the latest firmware to 13b rooted and as far as I know there is no firmware version that blocks downgrading via LGUP. However, If hardware problems is what your trying to avoid than stay far far away from the G4. It has a long history of hardware faults and I personally have lost 2 G4s due to hardware failure.
Thanks Justa. So it looks like I'm just better off sticking with the G3. So far the hardware has been fine, just hoping replacing the screen does the trick.
So I guess everything after the G3 has a locked boot loader?
