Rooting this device will trip knox, so does tripping knox void the warranty? I have heard different sides on that.
Tripping Knox will not void warranty, but you won't be able to use with a corporate Knox program, should you encounter one at work or whatever situation.

Rooting the device void's your warranty, so even if your don't trip Knox, you may be outta luck if you happen to brick your device.

this is false, rooting does not void your warranty, and you can always odin back to stock once we have the tar file. I've returned several phones to multiple carriers and they were all rooted.

This is still up in the air, I've read stories about people who had not probably with warranty after tripping knox, and I've heard of people having issues...
Rooting voids your manufacturer warranty if you trip Knox, if you go back to stock then you'll be fine for insurance etc purposes.

the same here I have even sent in a bricked phone with root and a custom rom with no problem
The debate of the century, I think... My understanding is that they cannot void your warranty for software reasons. They would have to show that your software caused a hardware problem. But... They sure could make your life miserable trying to prove your case if they wanted.
I too have had rooted phones returned for warranty with no issues, and I have had multiple rooted phones that I have turned in on upgrades with no problems (both Sprint and Verizon). Of course, your mileage may vary depending on if you get a mean spirited rep when the time comes...
Personally, I figure, if I am going to root a phone, then I am just not going to worry about Knox or warranty issues otherwise I would be a nervous wreck because once I get a phone it's like I can't NOT root it! It's an addiction... Hello, my name is Eric and I'm a root-a-holic...
I can't believe anyone who modifies their phone in any way that could brick it doesn't pay the measly $8 a month for insurance. It covers theft or loss, so figure out how you've lost your phone. And the $99 deductible for replacement is cheap. I've luckily never had to use it but I've had to replace my wife's Note3 three times for various reasons.

I'd rather put $20/month into a piggybank and get a phone off of Swappa if something terrible happens than have to go through a replacement process that will try to prove that your warranty is somehow void.

Rooting does void the warranty.
Many rom developers include this warning right at the top ---> DISCLAMER Your warranty is now void. I am not responsible for bricked devices, dead SD cards, or you getting fired because the alarm app failed. Please do some research if you have any concerns about features included in this ROM before flashing it! YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you.
Obviously if you flash it back to stock, your OK. However if you root and you brick the device, your carrier can legally refuse to fix or replace it.
here is what i got from Samsung United Arab Emirates / Dubai
(i did not flash stock rom nor i tripped knox i was just finding out if the warranty is still there if i tripped knox)

alzahmi . :
hi
LIVECHAT SUPPORT :
Good day valued customer. Thank you for contacting Samsung Gulf technical support. Kindly tell us how we may assist you?
alzahmi . :
i'm trying to find out if tripping Knox will void the warranty
LIVECHAT SUPPORT :
what exactly do you mean.. did you do anything on the device?
alzahmi . :
because i emergency flashed stock rom with odin and now the knox counter is 0x1
LIVECHAT SUPPORT :
im sorry to confirm that sir
LIVECHAT SUPPORT :
Knox is a security system of samsung
LIVECHAT SUPPORT :
it detects on the lower level of the architecture of the device if the software loaded is original or not
LIVECHAT SUPPORT :
as you had loaded with 3rd party which is not allowed by samsung, the warranty bit has marked it to be tampered
LIVECHAT SUPPORT:
as it counted, if the device has warranty, it will be considered as void
alzahmi . :
will i still have warranty for hardware problems like screen problems or buttons not working?
LIVECHAT SUPPORT:
im sorry, it will not be
LIVECHAT SUPPORT :
if you have issue with the device, you should have visited the service center
LIVECHAT SUPPORT :
at any rate, if there is any problem with hardware, it is possible to be repaired but charges will be incurred
alzahmi . :
but there are a number of people on enternet that flashed stock rom and their knox is tripped
LIVECHAT SUPPORT :
surely as the devices have knox security, their warranty bit has surely opened and it dictates it is tampered
LIVECHAT SUPPORT :
we understand you may be frustrated but doing such procedure in the device or even rooting is not allowed by samsung
LIVECHAT SUPPORT :
the usage of original samsung software provides security from high level to level of its archtecture... loading a fake software or unauthorized will make the device vulnerable from security threat.. that is why such checking of loading of fake software is implemented.. we are sorry to advise that if it is the case with your device, then the warranty is void
LIVECHAT SUPPORT:
*high level to low lever or architecture
alzahmi . :
it was emergency the device was laggy and i downloaded completely stock rom and installed it via odin and knox is tripped
LIVECHAT SUPPORT :
i understand.. but if you have issue with the device, you should have contacted samsung support to give you guide within the policy
alzahmi . :
ok thanks.
LIVECHAT SUPPORT :
you are welcome... may i know the model of your phone sir first
alzahmi . :
sm-n910c
LIVECHAT SUPPORT :
that is a new model... as i know commercial note 4s have no knox container only so only the security of warranty bit was affected.. if it is note 3 which carries the knox container, that knox container cannot be opened.
alzahmi . :
and what does that mean
LIVECHAT SUPPORT :
before in note 3 and s4, there is a knox application called as knox container in which we can store secured information there but recently it was removed becuase it was intended for corporate accounts only. so for those models like note 3 and s4 - if their software are tampered or rooted, when the warranty bit blows, then that application will not open already.
LIVECHAT SUPPORT :
however for note 4, it does not concern because it did not come by default.
alzahmi . :
yeah i dont have that app on my phone
alzahmi . :
so you mean other phone problems that are not related to security and software is still covered?
LIVECHAT SUPPORT :
no sir.. overall, the whole warranty is really void.. I was just confirming about the model because if you have the galaxy note 3, you may find that a problem. at any rate, you have the note 4 so you will not experience it. Let us just hope that the device will not face any major issue to avoid being recommended to visit the service center for any repair
alzahmi . :
i hope so

This thread was originally created by @Hawke84 over in the i9505 forums. A lot of people are unaware of KNOX or have no idea how exactly it works so I thought we should have a thread like this in our forum as well. I have sent @Hawke84 a PM and would like to let everyone know I take no credit for this idea. Huge thanks goes out to @Hawke84.
Please feel free to ask any question here and i'll do my best to answer it but hopefully some of the other members who know a bit more will also join in and help answer some of the questions people have.
What we know so far:
1. Upgrading to newer 4.3 Samsung firmware will most likely upgrade the bootloader to knox bootloader. This will give an additional 2 lines in download mode about knox status.
2. If the Knox Warranty Void line says 0x1 then you cannot use KNOX Software on your device. Your device has also been flagged as insecure. This means that if your workplace / company supports bring your own device to work for corporate emails, etc. and they use KNOX, your device will not allow this.
3. If the KNOX Warranty Void line says 0x0, KNOX will work and your warranty is still valid.
4. With the new KNOX Bootloader, root will work. However, rooting with CF Auto-Root will trip the KNOX flag. Someone else has developed a way to root without triggering the KNOX flag. (Root de la Vega)
5. If you try to downgrade to an earlier firmware / bootloader it will set the KNOX flag to 0x1 (Void)
6. Once the KNOX flag gets set to 0x1, there is no way to set it back. (Yet!)
Let me clarify some things. The KNOX processes and functions are already on the stock ROM, most devs remove them, though. So many of you with custom ROMs haven't seen anything related to KNOX.
What the new T-Mobile update (when it gets pushed out) is most likely to come with is a "KNOX Bootloader" which will introduce a thing called "KNOX Flag" which is similar to the old counter we're all used to. This is the counter that @Chainfire was successful in resetting with his app, Triangle Away.
Unfortunately, @Chainfire or anyone else for that matter, has not been able to reset the KNOX flag.
The KNOX flags is this:
0x0 = You have not tripped the KNOX flag.
0x1 = You have tripped the KNOX flag.
Again, once you trip that flag, rooting, flashing a custom recovery, etc.. there is NO way to reset it as of now. And any KNOX functionality on your phone will not work. But the worst part is Samsung will refuse warranty on your device if they see a 0x1 in your bootloader.
Another thing.. on the new bootloader, if you try to downgrade, even with an official Samsung firmware, it will fail and you will trip the KNOX flag.
So once you're on the new bootloader, there's no going back.
There's been speculation that there's an eFuse at play here.
Anyway, for this reason.. I am suggesting you all disable OTA updates and wait until a ROM is built without the new bootloader and all the functions (Wifi, MMS, etc.) are working.

[RESEARCH] Samsung Knox: Warranty Void Behavior
Everything KNOX...
agreed... I dont care about knox. since i and our company dont, but i do care about the stupid flag and them disallowing warranties even though that is not legal.. Hardware warranties should NOT be disallowed due to some s/w.

Indeed.
I don't mind Samsung at all for KNOX, but for the people that don't use it, it should be optional.

I agree. I mean, I understand why they do it; if some idiot roots and then overclocks the phone so much that it damages the CPU, then Samsung shouldn't have to honor the warranty. The device is designed with a certain thermal budget and going beyond that means all bets are off.
On the other hand, if say your microUSB port in the phone breaks off, that's obviously not something that rooting has any effect on; indeed, most physical failures not caused by user error are unaffected by root status. I'd like to believe that people aren't stupid enough to try and overclock the device beyond its thermal budget; its not a CPU where you can just stick a better cooler on and go. But you know what they say about assumptions...
I wish that there was a way for Samsung to honor the warranty on a case-by-case basis. Thermal damage to the CPU should be easily identifiable. I suspect the cost of having the phones examined CBC must outweigh any losses they sustain because of the "locks" they are adding (not to mention the huge potential sales to businesses and governments who want the security implementations).
It will be interesting to see what happens from here on out. I think we can see what Samsung's goals are (at least on the surface), but I wonder what effect Samsung's decisions will have on other phone manufacturers and the market in general.

All you wanted to know about KNOX Void Warranty 0×1
By tamirda • October 9, 2013
Screenshot_2013-02-25_11_35_AM
Recently, Samsung announced that her all new devices will get an Android 4.3 update that includes KNOX Security system. According to Samsung, these devices will get the update:
Samsung Galaxy S3
Samsyng Galaxy Note II
Samsung Galaxy S4
Samsung Galaxy Note 3 (already has KNOX Security system)
Most of the users don’t root their devices and use it normally and for them KNOX Security system is a great option.
But what happanes if we want to root our device?
Now the problem begins.
Normal(unrooted and so..) devices are flaged as KNOX Void Warranty 0×0 right from the factory.
When we flash items which weren’t signed by Samsung, it flags your device as KNOX Void Warranty 0×1.
According to Chainfire, KNOX status is indeed an eFuse. This means that even JTAG can not reset the KNOX status back to 0×0.
Some facts about KNOX status:
It isn’t possible to downgrade to KNOX-disabled firmwares/bootloaders (An attempt sets 0×1) (even though some people state, downgrade is possible when omitting the bootloader file in a firmware package). By downgrading from KNOX-enabled to KNOX-disabled firmware, your devices will be locked to installation of newer firmwares.
Let’s focus on that fact. As we mentioned above, Devices like S4, S3 and Note II which came without KNOX will get the KNOX system.For example, S4 I9505 got about a month ago 4.2.2 update that includes KNOX-enabled system(MH1). If you try to downgrade to KNOX-disabled system(MGA for example) your device will be flaged as KNOX Void Warranty 0×1 and will get a special lock – you won’t be able to update to any KNOX-enabled firmware even by ODIN. Samsung’s 4.3 update is KNOX-enabled, so if you tried to downgrade to KNOX-disabled firmware(for example MH8->MGA), you won’t be able to install 4.3 update.
This problem is only for devices which didn’t come with KNOX-enabled system from the factory(S4, S3 and Note 2)
Jeffery Butler confirmed this information:
FYI…Samsung told me that Knox warranty becomes 0×1(void) when the device with secured bootloader attempts to have non-secured bootloader. MH1 is the very first binary with secured bootloader. If MH1 is attempted to be downgraded to lower version(i.e. MGD) which has non-secured bootloader, then Knox warranty becomes void forever, and this means that the device can be used only for non-Knox device(no container can be created).
If you try to downgrade to KNOX-disabled firmware, you can’t install any new firmaware(that includes KNOX-enabled system) and use your device only with the old firmwares.
Even if you flash a KNOX-enabled firmware via odin (e.g. the latest fw) knox will be set to 0×1.
Flashing unsigned or modified images via odin will set knox to 0×1.
According to these two, flashing root/kernel/recovery/latest firmware by samsung/etc. will set KNOX status to 0×1.
Samsung stated, resetting the flag is impossible.
Chainfire confirmed that it is impossible to reset the flag.
KNOX is mandatory and can not be completely removed.
In custom roms we can remove KNOX apps, but the status remains 0×1.
Warranty Void is not a counter, it is a flag (0,1). We have never seen 0×2 or so.
Mirroring all partitions from a clean 0×0-Device to a 0×1-Device via JTAG produces an unfunctional device (reversible by restoring the 0×1 partitions on the phone).
Using JTAG or other repair tools to reset the flag is impossible.
KNOX bootloader verifies signatures of kernels and recoveries. No custom ones possible without voiding the knox warranty.
Again, if we flash kernel/recovery/etc. we will void the warranty.
This si how 0×1 looks like:
2rn7beq.jpg
This is how 0×0 looks like:
attachment.php
I guess you are asking yourself now, what the hell 0×1 means?
If your device is flageed as 0×1. you should forget about your warranty.
Chainfire and other people confirmed that your can’t use your warranty:
Worse than that, I’ve also been hearing that service center instructions are indeed that devices with this status tripped will not receive any warranty repairs. (Of course, the action they take may still depend on the service center). Their excuse is that the hardware is damaged by the owner. Seems Samsung is catching up in scumbaggery to HTC, who years ago attributed my HTC Diamond’s screen damage (digitizer detached) to the installation of HSPL
To anyone in the know it is obvious that this doesn’t really fly, and the eFuse blowing (is this the hardware damage?) is intentionally done by the bootloader when unsigned software is loaded.
If you want to read the whole Chainfire’s statement, click here.
What is eFUSE? it’s a technology that allows reprogramming a read-only memory chip in real-time, even though such chips come with hard-coded code that cannot be generally changed after manufacturing.
When flashing unofficial software on the device, the status of the system and KNOX is switched to CUSTOM while increasing a binary flash counter, which helps Samsung find out whether the device has been tampered with. However, while Chainfire’s TriangleAway app has let users switch the status back to official and reset the flash counter until now, the KNOX status is based on eFUSE – basically, once you flash custom kernels or root the Note 3, the KNOX code gets rewritten, and this constitutes hardware damage.
Well, all I can say is think twice before you play with your Samsung device. If you don’t care about warranty, and you like custom roms and cool stuff just be aware of this information and continue with what you are doing.

As you may already know, the latest Samsung firmwares came with a new secured bootloader. You can recognize it in download mode easily. It states: Knox warranty void: 0x0 or 0x1.
As for now, there is no way to reset that flag from 0x1 to 0x0.
Then I read in a comment of Chainfires post concerning that flag, that as long as you do not try to downgrade to a non secured bootloader, this flag will not change. He claims to have that information directly from Samsung.
https://plus.google.com/u/0/+Chainfire/posts
Has anyone already experience with rooting an "untouched" S4 which has the secured bootloader and can confirm or decline that?

Conclusions and Facts about KNOX-enabled firmwares (based on statements from chainfires post and it's comments above, ans based on this thread)
Not possible to downgrade to KNOX-disabled firmwares/bootloaders (An attempt sets 0x1) (even though some people state, downgrade is possible when omitting the bootloader file in a firmware package: see http://forum.xda-developers.com/showthread.php?t=2444671, not confirmed)
Even if you flash a KNOX-enabled firmware via odin (e.g. the latest fw) knox will be set to 0x1
Flashing unsigned or modified images via odin will set knox to 0x1
Samsung stated, resetting the flag is impossible
KNOX is mandatory and can not be completely removed
Warranty Void is no counter, it is a flag (0,1) it was never seen 0x2 or so
Mirroring all partitions from a clean 0x0-Device to a 0x1-Device via JTAG produces an unfunctional device (reversible by restoring the 0x1 partitions on the phone)
KNOX bootloader verifies signatures of kernels and recoveries. No custom ones possible without voiding the knox warranty
Assumptions on how KNOX flag in bootloader works:
Some experts think, an eFuse is involved. (http://en.wikipedia.org/wiki/EFUSE). An eFuse is mostly only incremential. Even unwriteable by low level tools or JTAG. But it is still not proven, that eFuse is used.

3:Can i install custom roms?
DeepankarS said:
You can do any customization on your phone like a normal phone, but customizing it means that you have triggered the KNOX counter to 1. Thus on a stock rom you can never use KNOX if KNOX reads 1.
FYI the MK4 (bootloader) or MJ9 (babseband version) has blocked installation of any custom roms on our n7100s via odin. You cannot even downgrade to 4.1.2 official via odin, So flashing via recoveries is the only way left.
And also it is recommended that you install custom roms via Philz/TWRP/CWM recoveries to flash custom roms and everything.
Hope the lil knowledge helped.

On the note 3 it's done by special bootloader leaked by sammy. The only chance for the note 2 is if note 2 bootloader is leaked. No other way.

And one more thing-if i send them phone i can't be sure that they will reset it instead of just replacing MB and write my old IMEI e.t.c

I-9192 official status again
i have installed a few weeks later a rooted rom from another forum, and triggered the knox to 0x01 (so i cant receive official updates from samsung)
but, today i needed to reset my phone to factory default, than i was curious to check the phone status, and for my surprise was "Official" again...
i read in various sites that the knox flag cannot be reverted... is that true?
the files i was used to root:
Odin 3.09
Kernel_root_I9192.tar
SuperSU_1.41.zip
the only bad thing is that i lost my root
anyone have the same result just reseting the phone?
thx and sorry for bad english
Soooo. As far as i know the knox wont get updates from Samsung and Block using knox app? And what features are lost from a triggered knox? I flashed the original firmware again and all its ok so far. Theres any blocked feature that o didnt realize?
Need help
I've a s4mini 19192 and today I flashed samsungs official KitKat update to my phone... I tried to root it like I rooted the 4.2.2 update... But can't do.... Then I decided to downgrade to the old version 4.2.2 but odin says can't.... And fails... Someone can help me?
Is it possible to check when the flag was triggered?
I was sold a GN3, in witch the KNOX flag was already set* and I'm trying to avoid a situation in witch the seller will say that I've set the flag.
* not checked beforehand - my mistake - but still I can return it or get a discount under the law
hello..just got the s4 mini dual sim 9192... 2 days back..i was on 4.2.2 indian firmware....checked download mode and it said knox 0*0...now i flashed the 4.4.2 firmware downloaded from sammobile via odin and when i recheck knox is gone....!!!!
just said binary and system which changed from official to custom once i rooted it with CF-root method(nothing else was working...saferoot/towelroot etc)..and as i seem to have read that flashing stock rom reverts these back to official...is it true?
and does this mean that my knox firmware phone has been converted to a non-knox one after kit kat upgrade?
please anyone let me know..thanks

I've been "out of the loop" for quite some time and much has happened to Samsung devices since my last one (Samsung i9000). Basically it is the terror stories about this Knox security thing that mostly concern me and brought me here...
I mean I like this tablet, I trully do, but if I'm robbed by android's main advantage (modifying the thing to suit your needs) then I have absolutely no reason to choose this.
I have already read a a couple of stuff but they are all concerned about s4 and note 3. What about this tablet (the WiFi version), is it ... secured too? Also I'm a bit unclear of what this Knox thing achieves, at first it voids your warranty, second does not let you to flash certain ROMs, but I'm unclear from/on which ROMs this is enabled or even if merely rooting your device would enable this. I mean someone may not be interested in aosp ROMs but still love some "optimized stock + custom kernel" will this Knox thing prevent him even from that?
If this is proved an unmodifiable device I'd think twice for it's usefulness, android's only edge is its "modifiability" remove it and you buy sth 2nd or 3rd tier...

I've been "out of the loop" for quite some time and much has happened to Samsung devices since my last one (Samsung i9000). Basically it is the terror stories about this Knox security thing that mostly concern me and brought me here...
I mean I like this tablet, I trully do, but if I'm robbed by android's main advantage (modifying the thing to suit your needs) then I have absolutely no reason to choose this.

You can still root and modify things, however, Samsung has taken the stance that since Knox has been tripped you must've been running Custom firmware/apps that can "potentially" damage the hardware so all warranties (at least from Samsung) are void....
The other issue is Samsung are updating bootloaders when you install firmware updates. If you happen to get a new bootloader then you CAN'T go back to a lower version of firmware, period... Doing so generally results in bootloops or stuck on Samsung logo until you update to the newer firmware again...
The downside to this is the nandroid backup you took just before updating in case of a problem is rendered useless, and in the case of the Note 3, Kies no longer recognises the new bootloaders so emergency firmware restore doesn't work...
Knox also tries to deny any app root access, some messenger programs were denied access as their permissions required root access. SuperSu has been updated now to work with no problems, until Samsung decide to interfere again....
Knox is also a secure container for your data, it was meant for security agencies and such to have a secure passworded partition in the software that doesn't allow anyone but the person with the passcode to access it. This is disabled after rooting as the system has been modified and can no longer be deemed secure....

So Knox is more about controlling your device than security as it is not optional (you cannot turn it off , right). Also about losing the warranty, well I was hoping to buy it from a reputable store in my country, even if Samsung voids my warranty can't the store itself honor it?
If not, if in fact merely rooting your device voids my warranty whatsoever than I'm most certain that this is not a device for me and I'm not sure for whom it is, I don't think android is a good os when decoupled from rooted apps (no xposed framework, no adblock, no virtual buttons, no gestures, no greenify), the experience is basically killed...
Even jail breaking your iPad doesn't kill the warranty as long as you install non jail broken iOS version on top... Bad Samsung, bad
OK, since I actually want to give this tablet a go I came up with a new idea. What if I trip up the Knox counter but then get back to stock firmware and *then* my tablet gets damaged? Would then my warranty be honored? The Knox counter can only tell you that it was tripped *once* but not what is/was happening at the time you got a defect.
Maybe my battery died, or more than a handful pixels died on me, all having nothing to do with me rooting my device at some point. Can my rooting still be grounds for samsung to dismiss my warranty? Because if so that is quite a scheme that Samsung runs.
Do any people had their warranty honored even though the Knox counter was tripped?
If you have a squaretrade warranty you should be fine with that excuse. However, Samsung will say that they cannot tell if the damaged occurred before or after the rooting occurred, thus denying you your warranty. Once the counter is tripped, from that point on the warranty is gone. My recommendation, get a squaretrade for 100 with a 2 year warranty and you will be fine.

Hi. I have the wifi only version of the tab S 8.4 (T-700) and it has the Exynos 5 Octa 5420 chipset. I read that it is possible on other devices with the same chipset to reset the knox counter back to 0x0.
What do you think? Anyone has any experience with this?
LE: after reading the original thread carefully i noticed that it's not a simple software solution. Maybe can be done in a repair shop
we, as end-users, don't have the tools to do so. The flag is resetable we just don't know how to do it yet.

Was talking to a sales type at BB about rooting/ROMs, etc and he related that often he's gotten tabs with Knox tripped. Says at the retail level he has the ability to reset Knox with software. Didn't press him but must say if true it would be the first I've heard of it.
I worked for Samsung at the store booth and we had no way to reset the counter or even flash stock firmware on a rooted device with much more tools and samsung specific software so i find that hard to believe lol. I am certain he was mistaken.

That was pretty much what I thought also....
If it was user possible, Chainfire probably would have found a way to "reset" the efuse by now.
Maybe those with JTAG equipment might have a way, but not heard of it yet.
But unlikely a simple app will do it these days, all known exploits have been patched by Samsung.
Plenty of info on XDA discussions etc. I just take the risk and root, and if warranty is not honoured, bad luck, I know the risk before hand.
I lost my warranty void because of this knox **** counter huhuhu :crying::crying::crying:
I bought my phone from O2 Slovakia and I'm using their services but I'd really like to put the latest CM12 release on my G3 (d855) since the official Lollipop update devours every little bit of my battery.
I've read somewhere that modifying the software on the phone does not void the warranty anywhere inside the EU but I'm really not sure about it since all sites still warn about voiding warranty. Who do I trust?

Rooting in the EU will not void warranty unless the oem can prove that rooting is the cause of the defect.
Quote:
All Android users were or are wondering whether flashing their device will void the warranties of their devices.
This concerns European customers (EU).
In short :
The FSFE (Free Software Foundation Europe), has concluded that rooting and flashing our devices don't void their warranties. Manufacturers can't refuse to repair a device because modifying or changing system software is not a sufficient reason to void the "statutory warranty". The seller has to prove that the defect is caused by user's actions before completelly voiding the warranty. Unless that, the standard 2 years of the warranty is still valid. So the Directive 1999/44/CE dictates1 protects consummers even if they have rooted and flashed their system in order to use custom ROMs.

So this means I can go right ahead and flash ROMs on my phone, as long as I don't brick it?

Pretty much so unless you brick it, fry your cpu by overclocking or flash non-lg3 software you should be good to go
