Also, one other thing to add... it does charge verrrrrryyy slowly when its powered off and connected. It loops and vibrates the charging icon with a grey spinning icon. It does charge though (about a 1/4 over a 4 hour span). So its not completely not working..whichi is odd.
[Verizon Samsung Galaxy S 4] Zelmo88:
Are you using the USB cable that came with the phone? Some other USB cables will charge, but won't transfer data. So, it may be the cable and not the USB port. Just a thought!
[Verizon Samsung Galaxy S 4] k1mu:
You can root using a Mac, or a Linux system. But I don't think that's what you're asking I think what you mean is "why do you need another computer to do this?"

The reason that you need a separate computer is that the security policy on the Verizon device doesn't allow you to push a file to the phone and make it executable. i.e. you can't get it to run.

Specifically, to root you need to run the supplied "getroot" program. ADB can be used to push that to the phone and make it executable:

So you now have a getroot program that can be executed to root the phone. The "chmod" command sets the "executable" bits so the program can run. You've got to do that to allow it to get started and root the phone.

So, let's get rid of the PC. Copy the getroot program to the external SD card. OK, so it's now on the phone.

You can't run programs from that external card, and can't set it to be executable. But the rooting scripts writes it to another place and marks it executable, so why not just do that from a terminal emulator prompt? So, it shoudl be easy - copy /mnt/extSdCard/getroot to /data/local/tmp/getroot.

Cool, that works. So now change it to be executable so you can run it:

Oops. You can't do that. Without that, you can't run it. Game over.

I'm not using adb to force use of a separate computer to run the root. I'm doing it because the policy on the i545 doesn't allow you to push a program onto the phone and run it unless you do it via ADB.

Some phones/tablets aren't so locked down, and so may be able to use a terminal emulator to do this. I'm going to be posting info this weekend on how to do that, which may help to get rid of the PC, kind of.

Any other questions?

As far as the "Custom" status goes, this is a FAQ. Short answer:

Do you want root? OK, then you will be running a non-standard system, i.e. customized.

Do you want to avoid seeing the Custom flag? If so, either run stock, unrooted, or use the Wanam hack to fake the status.

If you don't want to be running custom software, then don't. Go stock.

Finally, "Knox" is not a thing, it's a series of protective mechanisms, some of which we can disable on rooted phones. We can't override the Knox bootloader flag ("Knox warranty void") flag, however. Apparently the Knox container software uses that to disable the ability to use a container.
[Verizon Samsung Galaxy S 4] rolltide78:
Thank you very much for the explanations. I love it! First...I've tried using multiple USB cables and no go (except for the slooowww charge using the vibrate behavior loop). Any microusb cable used to work fine. I want root but just not on this device as I'm sending it in to Verizon. If I could get rid of the custom boot animation and the SuperSu app I wouldn't be wary but I just feel awkward sending a device back with these two items still visible ont he device. I'll root and load hypervisor on the new device when it arrives. Now, I'm just trying to get it to a state to send back and am trying to figure out my options.
[Verizon Samsung Galaxy S 4] k1mu:
Have you used the SuperSU "full unroot" setting to remove it? That'll get rid of SuperSU at the very least;

My Saferoot thread has unrooting info in post 2 - worth trying, especially before killing SuperSU.
[Verizon Samsung Galaxy S 4] rolltide78:
See that's just it....I took the MK2 OTA update from MJ7 thinking that is how to unroot and now I no longer have root. I get the binary not found issue when I try to launch supersu. Root checker confirms I no longer have root.
[Verizon Samsung Galaxy S 4] decaturbob:
I wish the moderators were more helpful so we could have a number of stickies in these forums. We could save so many from screwing their phones up as well as saving us a lot of time in constantly explaining the same stuff over and over again because some new comers don't want to take the necessary time to research the process. As you can tell, I'm getting a bit testy with new posters in some of my replies because its so obvious they put in so little research into what their phones are capable of taking for mods. This explains the background and how and why ADB needs to be understood as well as the ODIN process before you take the plunge. Three thumbs up to you!
[Verizon Samsung Galaxy S 4] rolltide78:
I apologize for my lack of experience with rooted with the Android platform. I think my downfall was relying too much on youtube videos by folks like rootjunky and galaxys4root. They are excellent at obtaining root but not so much on removing root and getting rid of the Custom screens, etc. When I tried to come here it was a bit overwhelming with all the variants, versions, and options. I thought I was doing the correct methods. I'm going to look into adb and understand more of the inter-workings now. Hopefully it won't be an issue with Verizon but I just wanted to do as much as I could to get it back to stock given the issues I have with my device and USB.
[Verizon Samsung Galaxy S 4] rolltide78:
Am I completely out of luck removing the padlock custom?
[Verizon Samsung Galaxy S 4] k1mu:
If you can't get your device to be recognized over USB, you're kind of stuck.

Typically, you'll at least see the "Verizon Mobile" disk drive show up when you plug it in. If you see that, try running the VZW_Software_upgrade_assistant.exe that appears - that will flash stock and clear the "Custom" flag.
[Verizon Samsung Galaxy S 4] metaphz:
Bingo! Your modifying a $700 device based on YouTube videos. At bare minimum one should take the time to read and understand the complete process. Yes it can be very overwhelming because of all the different information contained here. Stick with reading the most popular threads in the topic you want to learn about. They are generally up to date and contain answers to most questions.
[Verizon Samsung Galaxy S 4] decaturbob:
Spot on. Youtube videos offer some insights, but reading these forums is a must. I would never go into modifying a $600 or $700 anything without beeing 100% sure in what I was doing yet we see posters here that perhaps never even browse the forums for info and they mess their phones up and come begging for help. First step, take time to research....and I mean take some real time

[General AOKP Discussion] Fahrenheit:
I upgraded from 12/30 to 01/09 build and it seems to be a little snappier. I also notice more ROM Control options which is nice. A few issues I've noticed:

⚫AOKP GApps are missing the Genie Widget, Chrome, and Google Voice (maybe by design?)

⚫AOKP GApps uses the "Android Keyboard (AOSP)" instead of Google Keyboard. The AOSP version seems non-standard with the long-presses on keys and the lack of keys on long-pressing the period. Thoughts on moving to Google Keyboard?

⚫ROM Control from 12/30 had an option to automatically unlock when you enter the correct PIN (instead of having to hit enter). Will that come back?

Thanks for your work...this is still the best KK ROM out there (especially for an old GNex). Cheers!

we kept GAPPS that can be installed from play store outside the gapps package, so that user's who need it can download, and user's who dont need are not forced to use

Oh and I was wrong about the option to unlock phone when pin is entered...option exists, its just under Security ?

I did notice that the Location toggle doesn't seem to toggle though.

[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] herbs28:
I have discovered my tablet suffers what seems to be a common problem with other Note models.

I have been a little disappointed with battery life and today noticed the tablet vibrating as I was walking, it was detecting the spen removal every thirty seconds or so, even with the tablet in my hand and relatively still. This turns the screen on.

It is most likely going back tomorrow, sadly for a refund as they have no stock, I've had charging issues too. On two occasions it only reached around 53% powered off charging overnight and only hit 90% one evening when powered on, that said, this has only happened a couple times early on. Maybe just the battery finding it's footing and calibrating itself?

It got me thinking though, I'm using a snugg case with a magnet on the closure. Does anyone know if the spen uses a magnet in the silo?

I do occasionally find that with the cover folded round the back that it can cause the screen to go off, so the magnet must be of a reasonable strength. Maybe it's interfering with the silo detecting the pen?

Any thoughts please?
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Finalform:
Im pretty sure its not a magnetic sensor, maybe its a pressure sensor of some sort? (i really have no clue lol)

But I had the same problem with mine, and found that if i physically pressed down on the top of the pen when it was inside the silo,

it would temporarily resolve the problem.

if your s-pen isnt snug and can slide in/out, the tablet might not detect the pen as being inside the silo.

Got my exchanged and the s-pen is MUCH more snug, no problems whatsoever.

Im using the Poetic Slimline case (has magnets) and have been using it for over 2 months now, no problems whatsoever.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] ¿Will-it-Blend?:
Did you go into settings and turn off pen detection? Just a suggestion. I have not had this issues nor have I heard of it before.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] herbs28:
That setting seems to do nothing, even after reboot. Still detects the pen in and out. Is that normal? Doesn't sound like it.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] dt33:
Short explanation:

"An electromagnetic field is generated from a circuit behind the screen. The S Pen picks this up and uses it to power itself and figure out its position relative to the screen. It sends this, along with information from the S Pen button and the nib at the end, back to the Note."

[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Geordie Affy:
I'm sure S-pen detection is the feature where it lets you know if you walk away with your tablet without the s-pen.

My S-pen and Silo are both fine and it still vibrates and I have detection off too.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] herbs28:
From what I've read, the tablet doesn't have that walk away feature and it's limited to the note phones.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Geordie Affy:
Oh!....then whats this feature do:confused:

[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Bulbous:
S-Pen detection disables the digitiser if the S-Pen is IN the holster. It save a bit of power.

I have the HM5100 Bluetooth Pen. It works like this.

With "Disable pen detection" unchecked I can use the BT spen while the note' spen is still in the holster.

With "Disable pen detection" checked the BT spen does not work util I remove the note' spen from the holder.

[Nexus 4 Q&A, Help & Troubleshooting] Downloaded7:
Hi all,

I have owned my Nexus 4 for about 4 months now, and while I love the ability to customize my experience, I am always looking at ways of customizing that streamline things instead of adding more functionality. Rather than having 12 ways to do one thing at all times, I'd rather have the single best way to do 12 things at my disposal. I don't need HALO, the notification shade, and a notification widget all running at once to inform me about new notifications. When I look at the ROM scene on XDA, it seems like people are really interested in adding things to the standard android experience, but nobody seems to be working on trimming the unnecessary features away while adding things that work better/look and feel more elegant. I don't just mean debloated GApps packages, I mean ROMs that use Android's customizability do things better than Google intended.

To give a personal example, I am running stock Android on the Matr1x kernel with the Xposed framework installed to enable Pie Controls so I don't waste screen space, change the battery indicator to a circle/percentage, quick settings to get easy access to torch, settings, wifi, etc in the notification shade, and unicon to enable custom icons in the Google Experience Launcher so all my icons are uniform. This way I have as much information as possible easily accessible at all times, and my phone has a standardized look throughout. However, I feel like I am sticking it all together with tape and strings, and I am still stuck with some of stock android's bloat. It would be great if there were some people out there who shared a similar desire for streamlining the Android experience. Do any of you at XDA have any advice for me as I look for such a ROM, or is this about as good as it's going to get? If I could code I'd just do it myself :P.

Anyway, thanks for your time!

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] kirukisu:
Hello,

I'm using my N7000 with CM 10.2-20131214 for about third month and it got pretty slow and laggy. This is becouse of leftovers from previous data.

Using AndroBench random write score is 0.28 MB/s 73.3 IOPS which is dramatically slow.

There is an app for cleaning this mess called LagFix but N7000 is not supported.

I was also trying to TRIM using Terminal Emulator with no resault.

u0_a42@GT-N7000:/ $ su
root@GT-N7000:/ # fstrim -v /system
fstrim -v /system
fstrim:FITRIM: Operation not supported on transport endpoint

Is there any kind of solution for this issue, or I just need to do formatting internal storage from time to time?
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] Azeazezar:
No, there is no way to enable trim on the device.

It could cause a superbrick if you did manage to activate it.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] kirukisu:
Thanks for reply

Good that i didn't :<

Can formatting may be threat also?

Is it possible that this will be fixed in future?
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] Azeazezar:
Well, the fix is to disable what would cause a superbrick. (Which is why it failed in your case)

Completely fixing it, as far as i understand it, would requiring updating the EMMC firmware, which is risky, if not impossible.

You will just have to use the old garbage collection the chip has been using quite successfully. It seems to be doing fine.

No need for trim, or any special action on your part.

P.S.

Your random write speed is normal and identical to my own note.

Now, how often do you think random writing is bottle-necking your note?

It is likely something else that is the bottleneck.

My guess is that those guys at cyanogen are still using gpu clock speeds from the S2. I have not used that rom in a while, but i remember overclocking my lowest gpu step to 160 (from 100(CM), or 130(Stock) still nowhere near the top step that is 266) to give it a little boost.

I am not a developer, And i have not messed with that stuff for a while. So do your own research to what the problem is.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] JohnKC913:
As some of you may know, Sprint released a revision of the Galaxy S4 with the new ID of SPH-L720T (T referring to LTE Tri-band). Looking at the firmware versions, they are different than the non-tri-band SPH-L720.

I'm looking for rooted SPH-L720T stock firmware or a guide to rooting this tri-band version, but haven't had any luck.

I know the issues with CF-auto-root and the KNOX Counter with 4.2.2 vs. 4.3 thanks to everyone here. Now, I believe that the original shipped Andriod version is 4.2.2, but OTA will update to 4.3. Below I've listed the versions for both versions of the S4.

I haven't been able to find SPH-L720T 4.2.2 original firmware tar either (if it even exists). I'd be happy running rooted 4.2.2 or 4.3, but don't want to deal with the KNOX counter/no-triangle if I don't have to.

Any thoughts, ideas, or what it would take for me to dig further? Also, the SPTA vs. SPTE version prefixes don't seem to point to a tri-band or non-tri-band version.

I suspect since Sprint will be selling these going forward as their flagship with Spark, this will eventually need to be figured out. Any help would be appreciated...and I'm happy to research whatever I can.
