[Q] SELinux Permissive on US Cellular G900R4 variant - Galaxy S 5 Q&A, Help & Troubleshooting

It's reaching 4 AM and I still haven't found a kernel that has SELinux permissive and firmly states G900R4 support. I just hard bricked my S4 a few weeks ago rolling the dice with a maybe kernel. So as expected I'm a little paranoid with my shiny new S5.
I can deal with a "More than likely" so long as I can bring it back with Odin or something. I'm tired and rambling. Anyone who can help would be greatly appreciated. This is literally the last prerequisite before I can start doing the compiling/other moderately geeky Linux things.
Thanks.

You should do a more in depth search. A cursory search shows at least one permissive kernel where posters (in the support thread) say that it works for the USC variant e.g. http://forum.xda-developers.com/showthread.php?t=2714159
Keep in mind that permissive rights requires a custom kernel, which in turn requires an unlocked bootloader. Presumably the sm-g900r4 has an unlocked bootloader. Just realize that it is a prerequisite.

I have asked about issues with the other roms not working. I lost calling, texting, and could only use wifi with all roms. I also had to remove the SD card prior to the phone allowing me to activate after flashing back to "stock."
I have not found one that works. I tried Phoenix and Alliance roms at first and was tired of flashing back to stock. You CAN use xposed framework and I have used kernels like Blaze. That is about all I've been able to find. You can find dedicated US cellular forums BUT you won't find much there unless something changed in the last day or two. Nobody would answer my questions about why their roms would not work and possibly how to get them to work Sorry, this is about all you'll find. I had a few issues and my threads were also deleted

I have unlocked every USC phone I've ever had...there's plenty of devolopment out there for USC phones. I haven't seen anything other than custom kernels yet for G900R4 though.

There aren't a lot of USC users here so we don't know much about your system. In the past, USC has locked their bootloaders and that is the key reason that you don't see much custom ROM development.
Also, USC (along with Sprint, Verizon) still use CDMA while the rest of the world is using GSM. That basic incompatibility also deters wider development.
Have a look at the Safestrap thread in the Verizon S5 forum. Safestrap is an app for loading an emulated custom ROM + recovery and can probably be used for USC as well.

Does anyone know of a kernel that has SELinux set to permissive that will work? That's honestly the last thing I need. I wanted a bootloader unlocked phone that ran off CDMA so I can use it where I live so US Cellular seemed to be the solution.
US Cellular confirmed that the R4 has a unlocked bootloader. I am running a stock deoxed/debloated touchwiz. I am super surprised and disappointed that there hasn't been more interest and development for this phone. I am so tempted to trade it for a different.

I'm running a g900r4, (klteusc) as well. What rom are you using? I've been all over the gs5 unified and initial developments sections, and am currently using the cm11 unified while waiting for the slim rom unified. I'd gladly prefer a bloat free touch wiz though it seems the stock based roms are exclusive to g900f and the like.

You guys want this http://teamuscellular.com/Forum/forum/411-galaxy-s5-romskernelsmods/
CM11, kernel w/o SELinux Enforcing, other goodies.
Head over to teamuscellular.com/forum and you should find a few available options to try. Including stock deodexed ncf ROM(touch wiz). And other custom Roms ported to USC. Like "cm 12 lollipop alpha." Looks good but no customization. As well as all stock Odin flashable zips. Some others like alliance and beanstalk have been ported, haven't tried those though. Hope this helps. Enjoy!

[Q] How To: Root Verizon s4 SCH-i545 version 5.0.1

I have searched and tried but i cant find any info on my specific phone . I have rooted other phones and this one seems to be the most difficult! Any help would be highly appreciated... heres my info.

thank you
http://forum.xda-developers.com/galaxy-s4-verizon is where you want to go. This is the international S4 forum.
In short, your difficulties in rooting come from Verizon locking the bootloader.
WIsh i had found this thread yesterday since i have spent all day trying to figure out how the root this phone.... now i know why i cant.
bootloader locked
After reading your reply, I understand that there is no workaround for unlocking the bootloader. I was under the impression that this kernal SCH-I545_MD2_423399_Kernel.tar.md5 was for that. Of course it didn't work using Odin_v3.07.zip it kept failing.
The kernel and the bootloader are two different things. The bootloader is low-level firmware designed specifically to prepare the device to run the kernel. The kernel is the heart of Android. It provides the interface for the rest of Android to communicate with the hardware.
In devices not sold by AT&T or Verizon, the bootloader usually only checks to see if a kernel is present. If a kernel is present the bootloader hands off control to the kernel, which starts the operating system. In the case of AT&T and Verizon, and I am only speculating here because I have neither AT&T nor Verizon devices, the bootloader checks the kernel to ensure the kernel is not only AT&T or Verizon-approved, but the same age or newer than the bootloader, before allowing the system to boot. To prevent people from replacing this bootloader, AT&T and Verizon encrypt it so the bootloader's code cannot be manipulated to bypass the checks.
With an encrypted bootloader, rooting and custom ROMs are virtually impossible. Your attempt to install the kernel failed because the kernel was older than the bootloader. This is why, if you live in the US, you do NOT purchase a phone from AT&T or Verizon and instead, you do one of the following.
Purchase a device from T-Mobile, either outright or through installment plan. T-Mobile does not lock its bootloaders. You could also purchase a device from Sprint, but their service is the worst of the four major US carriers.
Purchase a device directly from Google (i.e. Nexus) or from device manufacturers like Motorola.
Purchase an international device and have it imported, keeping in mind that LTE may not function due to frequency differences.

Samsung Galaxy J3 SM-J320VPP Root help

Hi, and thanks for reading. i would like to know if theres a way of rooting the celphone Samsung Galaxy J3 SM-J320VPP. ive see Threads on sucefully rooting others models but not this one
I agree any dev out there want to let me know what you might possibly need in order to begin to exploit the boot loader. I know that the Samsung n4 fix is for a different chipset but there has to be a way to bypass Verizon's DMV so I can dump the boot loader and system and upload it for the community. I really really like this phone for its price point and I don't feel like that it should be let to the side because it's not a flagship. I'm not a dev but I'm also not new to the capabilities of this community. Any Assistance would be great
My issue is somewhat different, I have a banking app that reports my J3 as rooted (no other apps do) and I need a way to reverse or work around this flaw. The banking app does state for Galaxy S5 model that Android 6 Marshmallow is needed and I know I'm only on 5.1.1, but I'm not sure if the kernel and baseband used are the same.
Any help or advice appreciated. Or if I can root, update to 6 and then unroot to resolve this.
Any news? Just bought this phone on Verizon
No rooting so far. Kingo- and Kingroot APKs and PC versions fail to root, no custom recovery to flash SuperSU, and no vulnerabilities to exploit. I've had this phone for about 5 months now, and nothing sticks. But that's the way it goes with Verizon- branded devices - because the boot loader is locked there isn't much that can be done. The most I've been able to do is "convert" it to a SM-J320V by flashing that firmware via Odin. Still can't use non-Verizon SIMs though.

Does converting it allow you to use Verizon MVNO Sims without paying the ransom for a month of verizon prepaid service first to activate the phone ? I know you said no non Verizon sims but nkt sure if you meant MVNO too

Root Questions

I've rooted every phone I've ever gotten, mainly for adblockers.
I'm aware Samsung has e-fuses for knox in the past and I had no use for it. However, I'm new to s7 and not sure about private mode or any other new knox feature since note4.
Is there a way to root stock so I can install adblockers but not break knox or other features? What all will break exactly?
Furthermore, is it just root at this time or recoveries too? I don't even want to flash anything, just get root.
I have the master USA race T-Mobile version. I hear so far that it's only the Int'l models that have recoveries atm
Bump?
Anything that modifies the kernel will cause the efuse to break including rooting and recoveries because of dm verify.
currently snapdragon S7E can not be rooted effectively because the bootloader is locked and most developers will not touch them for now. Maybe in the future.

Bootloader unlocked, can I use any rom?

So Ive had this Verizon Note 3 since day one. Finally unlocked my bootloader... What are the rules on what I can and can't do now. Can I install any Android rom? Can I only install note 3 roms from any carrier... Can I install only Verizon note 3 roms? Or is it a hybrid... I can install any rom if I replace the firmware and or modem.
I really want something on 7.1 but I'd rather take 6 and have something custom... Fast and responsive.
Thanks community.
You are in luck. :crying:
There's hardly anything to choose from; maybe 3 or 4 ROMs and about the same number of kernels.
AFAIK, there are no Nougat ROMs and only one Marshmallow ROM (AryaMod6.6).
Normally, when a dev ships a "ROM", there are two important pieces: the /system image (what some folks call "the ROM"), and the boot image. The boot image is what some folks erroneously call "the kernel"; but it is really a combination of kernel + ramdisk. The ramdisk has all the scripts in it that the "init" process reads to start up all the low-level daemons and services... as well as the Android UI as well.
The kernel is very tightly tied to the specific hardware in a given handset - both the processor/gpu and all the sensors/leds/peripherals.
So that's the reason you can't just flash any old ROM. In the least bad case, your device wouldn't boot; in the worst bad case the kernel would boot up far enough go off in the weeds and possibly damage some of your hardware.
You might be tempted to think "we'll, what if I find a boot image for the "hltevzw" SM-N900V device... can I flash that after I have flashed 'any old Android ROM'? Won't that take care of things?"
Well, not really. The system library binaries in /system are possibly compiled with instruction-set optimumization tweaks that are only supported by specific CPU and GPU hardware chips. Moreover, other peripheral chips such as GPS have unique "downloadable" vendor firmware in the system image... so again, there's the issue of hardware dependencies of the /system image.
Beyond that, there's carrier-specific "setup and activation" software that differs between ROMs, so even using ROMs that are from a different carrier's version of the exact same handset hardware might not work fully - specifically in the telephony function areas. Everything else might work fine though. For instance if you wanted to use the device as a WiFi-only unit for kid's games etc.
Note BTW that the "International" Note 3 GSM phones are not the same hardware - they use an Exynos processor.
good luck in your quest
Thanks
That was very helpful... Looks like Araya is my best bet. I'll leave jasmine rom to try it.
I was hoping that I could get another note 3 rom on this forum and flash the CDMA modem for networking... But doesn't seem like that's an option.
If I'm still stuck to Verizon Note 3 rom... What is the purpose or benefit of unlocking the bootloader... Was that really just to avoid Odin so I can flash my couple rom choices easier?
I appreciate your time!

I might have very slightly overstated the case for pessimism. There is a "consolidated" Verizon Note 3 Forum which is meant for devs to provide development tools and even ROMs that could potentially be used on devices from more than one carrier. But the world being organized the way it is, that means that you are more likely to find multi-carrier GSM ROMs over there than multi-carrier ROMS which support GSM and oh by the way CDMA and LTE as well.
If you want to fool around over there, I recommend that you proceed with great caution to make sure that the ROMs you choose specifically target Qualcomm MSM8974AB Note 3 handsets, and you should read the developer notes very carefully to see whether you need to flash an "hltevzw" kernel separately. If the dev does not mention "supports hltevzw" or "supports N900V" (for example here) you might be taking chances with your hardware.
I suppose it is possible that the radios are 100% "software defined" in the sense of which bands they can support. Maybe you can get what you want by simply flashing the desired carrier's "modem" firmware, but I have never done that so I can't say for certain whether that works or you are risking a brick (or hardware damage) by doing that. I simply don't know (e.g.) if the chips and antennas in a T-mo version of the Note 3 are identical or different from a Verizon Note 3's hardware

Well, for one - having a custom recovery allows you to make backups - even if you never change ROMs
People don't think of backups as being "sexy", but they allow you something which is really valuable: freedom to mess around and experiment with the knowledge that "if something goes wrong, I'll just restore the backup".
And with Odin, you only had the choice of Stock Roms. Now you have a few more.
cheers
Yes you can install Any rom for note3
Here is my experience with installing roms on note 3 after unlock bootloader
you should Flash twrp-2.8.7.0-hlte-4.4.img by ODIN for the hlte roms or twrp-2.8.7.0-hltevzw-4.4.img if you looking to flash verizon roms ,
im on Phronesis Rom N7 now and i tryed many roms
AryaMod N7 & S7 Edge
MagMa-NX from NXT TEAM
Resurrection Remix Nougat 7.1.1
CM 13 ROM 6.0.1 for Trader418
Purify CM13 6.0.1 ( the best CM13 till now )
and more ...
i have only one problem that i cant get LTE in mobile network always on H+
i tryed to add screenshot but i couldn't its my firist reply :laugh:
@ALPHA85
Pretty informative first post - thanks, and welcome aboard!
Are you on a Verizon SIM? If not, have you been flashing modems from other Note3 devices?
Just curious; I don't have much experience with radio issues or carrier activation issues. Trying to port a carrier-specific ROM elsewhere (esp starting from a VZW ROM) looks like a massive pile of interlocking software dependencies, though. My respect to anyone who can succeed at it.
Feel free to write a brief summary about what's broken in each - any of them have NFC working? I was on CM13 (trader418) for a long time and would have been happy to stay there were it not for all the GPS issues.
Thank you ,:angel:
i dont use Verizon SIM becouse im from egypt, i bought my verizon note 3 by wrong , when i bought it i saw N9005 under the battery and in the boot screen also inside the rom ,it was lollipop 5.0 ,but sinse i did factory rest i surprised it change to N900V even the imei changed , till now i cant understand how they flashed N9005 rom for N900V device with locked bootloader
i'm on OF1 bootloader unlocked and i flashed PL1 Modem i thought maybe it help me to get LTE but still the same H+
about NFC i really didn't try it at all , i always disable it by titanium pro

When you first got it, did it appear to have a Verizon ROM on it? (For instance, the Verizon splash screen?) Or some other carrier's logo?
Actually, that cleared something up for me. Well, except for the part about the IMEI changing
Apparently there were both LTE and GSM models of the "Note 3" that were sold in international markets. I understand the LTE version was originally sold in China, but the GSM model is more common?
The SM-N9005 is an LTE phone (I don't know about CDMA) with the Qualcomm MSM8974 processor
and the N9000 is the GSM model with an Exynos 5420 processor
So that probably explains the binary compatibility of the SM-N900V and the SM-N9005 - same processor, and both phones were designed for LTE service.
But your report should give @cyberoptics a little less pessimistic view of things; thank you for that.
But I wouldn't go so far as to say you can flash ANY Note 3 ROM. Even though both the Exynos and Qualcomm processors use ARM cores, they are fairly different - the Exynos has 8 cores, half of which are Cortex-A15, and the MSM8974 has only four cores which are Krait- something or other. I think they are not quite compatible. Note that in theory, ARM code that was compiled to earlier standards (e.g. thumb, armv5) would certainly work on both devices - but if they compiled ALL the code in ROM libraries that way they would be giving up a lot of performance on either device. So.... to the extent that they target processor specifics for either Cortex-A15 or Krait, they will be incompatible.
cheers.

bftb0 I just wanted to thank you once again for your consistently helpful, verbose posts about the N900V. I've been using CM13 thinking it was the best thing going, when, as nice as it was at the time, it doesn't hold water compared to AyraMod, which I switched to yesterday after reading this thread.
Now my GPS won't take me sailing past Easter Island when en route to a noon meeting downtown. Maybe Google Cardboard will even work, now that NFC appears to.
Thanks again, and please don't ever bore of being a great and helpful resource, we need you!
