[Q] Root limits - Samsung Galaxy S8 Questions and Answers

Hey I've read smth about a 80% charge limit after tripping knox, but couldn't seem to find anything about it in the root threads, is it true and are there any other limits besides the unusability of knox required apps and some banking apps...?
Thanks in advance .

Well I haven't rooted since Note 4, but as far as I remember the ROM's were worth it on that device and I didn't rly miss the samsung features (maybe cuz I rooted the same day of gtting it).

Somewhere along the way I kinda stopped counting bricks ...

Yes we can only charge to 80% I found a method to get higher. I wouldn't trade root for anything on this device. It makes it bearable. I run modded TouchWiz and viper. Ui tweaks. There's very little you can do to really brick your phone as we still have locked bootloader Most hard bricks are recoverable. I prefer rooted nougat over pie any day of the week.
Btw bricks are fun. Fun to figure out why and how to recover.

The bricks part xD, is the charging over 80 stable tho, can you post the method?

Another thing, charging over 80 isn't recoverable by just reflashing the official stock(ie unrooted and all), right?

Yea it is. It a limit implemented by the kernel we need for rooting. Once the stock firmwares kernel is flashed back all undone. No tripped Knox.

Which model do you have. You can't trip Knox on the us 950Us. And the 950fs do not have the charge limit. If you flash back stock Samsung pay and all the banking apps will work again on the 950u

[Q] Yet another Root and KNOX tread.. What about NAND?

My phone is SM-N9005, with 4.3 stock and the dreaded MJ7..
I understand that there still is no way to Root this device without flagging the [email protected]@# KNOX and void any warranty..
I'm going to wait a couple of days for a possibility to root my beloved Note3, without triggering KNOX and then I don't think I kan live without Titanium, Exposed and Tasker++... :fingers-crossed:
I'm wondering if someone can explain to me; (I'm a noob and I know it) is the information Knox 0x1 stored in flash memory (NAND)?
And if so, and i had to deliver my phone for service some time in the future.. Would it be possible to make Nand corrupt beyond recognition and then get warranty back?
If they can't see anything wrong, they can't claim that I have been rooted..
Or should I just try too brag them with some baked goods and hope for the best?
I really hate that Samsung have done this with an "open" OS, and if there's no good work around in the future, This will be my last Samsung device!
Btw: This is my first post here on XDA, and sorry for my "English"

Apparently people have done this when they can't boot and have rooted OS. Don't know if it works as I haven't needed to try, anytime I had a warranty claim the problem actually fried the MB by itself.... No help needed...:laugh:

I thank you for the comment, but i do need an first hand experience before I fry my note..
Don't know why, but I'd be more comfortable with a full whipe of NAND, if that's the place KNOX is stored..

KNOX is stored everywhere, - No one knows for sure where the counter 0x0/0x1 is located, hence no one being able to reset it. It is possible it's in NAND, but then again, it might be somewhere totally different.

In all honesty I doubt a few days will make any difference, there isn't even anyone working on rooting without tripping KNOX, especially now DG and CF have given up and said it can't be done due to the bootloader...

Well, then it seems like this is my last Samsung device..
It where nice as long as it lasted.
Any thoughts about the NAND?
If that is corupted, wouldn't it be difficult or impossible to read the internal SD?

It is possible, but we don't know what kind of tools Samsung potentially use to debug a device properly. But then again, who knows

restore... unroot questions

What would happen if I allowed the at&t update to happen? I am rooted with towel root and added titanium and safestrap. that's it. Can I restore to the original AT&T rom? I am obviously on AT&T and rolling with the s5 Active.
not really impressed with the root on this particular device...Samsung will allow a ton of custom setups and I can deal with the bloatware compared to the instability of just being rooted...Ive had more call drops and stutters and blackscreens since rooting... no biggie
Just want to know if I can just apply the update or do I need to jump through hoops?
Please understand that I'm "slow" and rode the short bus to school...Please refrain from treating me that way. im not all there.. just help Thanks.

I suggest you learn more about rooting. It's awesome once you know how and what you can benefit from it. Worth the Knox 0x1 at some point.

The update may comtain a patch for Towelroot so you might not be able to root after that, CF Auto Root will work but it will trip KNOX.

If you notice... Ive been a member of this forum for 5+ years... Post count means nothing...while others are posting, I'm "learning more about rooting." Plus, I'm highly gun shy about posting idiotic and useless comments around here. There is no tolerance for such sensationalism..
So, thanks for the suggestion but I'm as well read about rooting as you are. Yes, its awesome...I know. Thanks, though... but The Problem seems to be that (with AT&T) stability is compromised. Worth the ability for me to lose bloatware? ...especially with a highly customizable Samsung?? Questionable right now...
Still "learning."
Just wonderin' about restoring...

[Q] Is it worth to trip knox

Only two months remaining in my warranty. should I trip knox? If ktoonsez kernel comes for TW lollipop then I for sure will trip knox. But other than ktoonsez kernel, Is there anything worth to trip knox for?
I tripped knox 2 months after purchase.
I don't regret it at all. I can backup my apps with titanium backup. I can use viper4android. I can increase and decrease the performance (depending if I need battery life or not).
I felt very restrained without root.
Finally, I tripped my knox...!!!

Knox Bootloader

Hello, just wondering since it's been a while, if anybody found a way to downgrade the Knox bootloader-enabled one to the one before? From 4.2 if I remember correctly? Thanks!
As far as I know, no.
I think people even stopped trying.

That sucks, the S4 was a good device, before I had to send it in for repairs! They upgraded me to 4.4 with Knox, and now it's just awful, sadly. Oh well.

Why? I got mine with Knox, but I don't see the big issue with it.
Anyway, you can always flash custom ROMs to get rid of Knox. Or root and delete Knox apps from your ROM.

Does Samsung Pay work on U firmware?

Yes, just fine.
Yes it works. Currently using G935UUEU4APL4.
What's the advantage of UFirmware? From what I've read, it has less bloatware but just eats a lot of battery.

It reportedly consumed more battery on rooted devices, unrooted should be fine, though I have had no problem running on it (though I have a fair bit of adjustments applied). The U-Firmware performs better for me and a friend immediately noticed how much smoother his phone performed after switching. Wifi calling still works, though I think you loose VOLTE & vide calling. Less bloat could probably lead to better battery anyways, though to be safe you could always switch to apk1 and wait for Nougat.

On T-Mobile VoLTE still works, but the built-in video calling is absent on the U firmware.
I thought after you tripped Knox by rooting there was no going back, and Samsung Pay is permanently broken. Is that not the case?

Rooting does trip Knox. Flashing OEM firmware via Odin doesn't. Once you trip Knox, Samsung pay will not work anymore.
To answer OP's question, yes it works. I've been rocking G935U latest firmware on my T-Mobile Variant and works beautifully. I strongly suggest you move to U firmware.

Huh. That's very odd because I've rooted my S7E several times and I'm still 0x0 and I'm not rooted anymore because I like the use of Samsung Pay.

That's weird that it doesn't trip yours. All the posts I've seen on XDA and everywhere else say it does. Did you go as far as flashing a new recovery? I've tripped mine on my Note 4 before (not doing on my s7e because I still like to play it safe). How did you root yours? If that doesn't trip Knox, then Samsung just had a major mishap on their security. Good for you then. :good:

We can't flash a new recovery because the bootloader is locked.
You're writing in the T-Mobile forum man.
None of our Knox is tripped. We get root through an engineering kernel and flash through Flashfire.
Samsung Pay doesn't work but our Knox is still 0x0.
Pretty sure the only root that trips Knox is CF-Autoroot that you flash through odin, that's only available for the F model and the china snapdragon model.
