Rooting PK1 and unlimited Tmobile Hotspot

[xena499]

I' m hoping some experts can chime in.
I rooted PK1 about 10 days ago. Followed the Verizon S7 forum that had clear instructions, and used the v15 fixes + debloater.
I made sure the governors were set to interactive.
Despite all this, my phone was extra buggy and had lag, compared to stock. It seemed to get worse with time.
Then on day 6, after root, my phone started boot-looping on the tmobile logo and vibrated.
I un-rooted back to PIA, and tmobile still seems to be monitoring hotspot use, I thought was part of the PK1 OTA.

So, my questions are:
1) are those rooted on PK1 stable, like stock? OR is there still stability issues, beyond adjusting the governors to interactive?
2) what are people using to successfully circumvent tmobiles new hotspot throttle. ( .5kbs or pay $25 per month).
xtether module in xposed, or WiFi Tether Router (root). ??
what is working?
thanks in advance !

I'm not on the PK1 firmware yet, but I just upgraded from PG1 to PIA.

As far as performance goes, I found this thread VERY helpful: http://forum.xda-developers.com/ver...uide-fine-tuning-performance-battery-t3417804

Maybe it will serve well for you as well. As far as rooting is concerned, not too sure from personal experience, but I heard the ENG boot works with the newest firmware and I'm guessing the modified SU should work for it too.

If you would like to try reverse engineering the files yourself, maybe these guides will help out:

In regards to removing bloatware, I prefer removing apps over services because you never know when you might need a service that you accidentally removed from a previous time. Also I've been going through many cases of trial & error with removing bloatware and a few times ended up messing up other apps in the process that would force crash, but with my current setup everything seems to be working well.

If you need help with removing bloatware, there are 3 apps that really helped me out.
https://play.google.com/store/apps/details?id=com.piriform.ccleaner <-- Surprisingly ccleaner is awesome for the android as well as the PC.
https://play.google.com/store/apps/details?id=com.jumobile.manager.systemapp&hl=en <-- this is very useful as well

Another tool I found very great and you run this from your computer is Debloater: http://forum.xda-developers.com/android/software/debloater-remove-carrier-bloat-t2998294

Hope this helps. I'm trying to currently work on a way of creating custom odin flashable roms so I can optimize roms to the best of my ability and provide the community with more options as well. This is still a work in progress though. :S

EDIT:
Here is an output of my program list. It was too long for me to post directly in the message
adb shell pm list packages -f

thanks a lot!
I have read about ENG boot being an improvement as well, yet nobody is stating that it is stable as it is prior to root, just improved lag, performance and stability. I know in my experience, root, for the first time in 8 years of rooting is not worth the benefits. This is sad. Must be stable. (in addition -no roms, no nanroids, no samsung Sumsung Pay..etc..etc..) So I'm hopeful things will change soon, or will be forced away from Samsung. Tmobile privacy invasion issue, and bait-and-switch with their plans is even further less encouraging news. Imagine "unlimited" = less.... wow.

Well said, and I completely agree. I've been a BIG fan of previous Samsung models, but it seems with every new model that comes out there are less and less options for customizations. I'm currently in the process of trying to figure out how to repack tar.md5 files *properly*.
I've gotten close, but then it fails right at the very end. I'm still waiting for a response from someone hopefully with more knowledge than I, but I guess I have to be patient. Here was my thread: http://forum.xda-developers.com/tmobile-galaxy-s7/help/creating-flashable-odin-file-t3500139

Any way, I'd love to see more customization for the S7. I think it's a great phone and it has so much potential. I also love android and always felt it gave users more ability for customization as opposed to Apple. Like you, I just hate all the bloat ware and all the crap that comes on phones these days. Not only that but the markup price is ridicules. Having to pay $600+ for a phone that is "laggy" due to all the bloat on it is frustrating to say the least. This is why I'm trying to give the community more options or at least steer them in a direction to customize their devices easier. Currently despite all the various amounts of software that is provided through this community I feel like there aren't too many people that know how to properly use it.

Any who, good luck with your phone. Let us know if you figure anything out with it. Also, are there any significant advantages with the newest firmware over the PIA? I usually like to hold off from upgrading right away so that all the "kinks" get worked out first since it's difficult to downgrade afterwards.

I was rooted stock and I used the fixes.zip , I stopped using the debloater because my phone had issues after.

Its bootlooping because you accepted the security update popup.

 

[m0d hipp¥]

You know what, that happened to me once, I forgot. What I needed to do is reflash the ENG boot file then when I got back into the phone, remove and reinstall SU. After your phone restarts, go into playstore --> you apps --> and uncheck "Auto Update" for Super User.

thanks I tried going back to PIA and used fixes only, as the debloater might be the culprit !

I got it work now here:

@xena499 How were you able to downgrade the firmware? I tried downgrading through ODIN and it wouldn't let me.

@xena499 How were you able to downgrade the firmware? I tried downgrading through ODIN and it wouldn't let me.

yes. If your using the firmware in the verizon rooting forum, that stumped me too. It doesn't work.
Must be PIA (sept 27) or newer. I got the firmware from here The sammobile site.
and flashed fine with odin. Then used the established root method from the Verizon forum, using only the V15 fixes and NOT the bloatware remover.

Still testing the root stability (2 days driving). Seems ok, but not as stable as stock so far, but acceptable for me. Cool, no battery drain, but have noticed some lag/ and buggy things that I'm deciding whether or not was a settling that was not apparent on stock w/o root.
In addition, when I was given this loaner phone from the N7, the store migrated all my data and apps using the built in sammy prog. I was concerned how this would affect my phones performance in the long run. 3 "upgrades"/ swaps later of the same technique of migrating apps/settings/data between different phones took it toll. So the bootloop issue earlier forced me to unroot and start fresh, without a choice.... The proper PIA flashed on my device (no root of course) was rock-sold stable for the few days I tried it.

Thanks for the response. I have a SM-G930T and the firmware I am running currently is the " G930TUVU4APIA" stock. I just am using the ENG boot file and removed a bunch of apps myself (not using the v15 debloater or fix). Any way, the PIA firmware is still a little sluggish for me, and I was thinking of going back to "G930TUVU3APG1", but every time I try to flash it through ODIN I get an error. Something similar to "SW. REV CHECK FAIL : FUSED : 4, BINARY : 3".

And I didn't think that a verizon firmware would work on a tmboile phone? They're completely different hardware? Like GSM vs CDMA? Or am I missing something?

NO you need the Tmobile files, available in links here, or better from the sammobile.com site i mentioned above.
I would never flash verizon firmware on a tmobile-connected phone.
In addition, are you following the verison unroot method from the verizon s7 rooting guide? the verizon root references for me were just where the best info is for all S7 people, but the software links are to older firmware that didnt work...
Basically, you are using odin to flash ALL files at once (ie AP, BL, CP, CPC), then you are back at tmobile stock as per date of package used (PIA, PG1..etc).
Earlier versions before PIA do not flash, for me. I believe this is b/c i took an OTA security update that did something to prevent this. PIA worked fine for me, and is working not bad.
I'm satisfied for now, and I will wait for stable Nougat before anything else, and done with customizing and playing.
I hope this helps you

Getting the same Error while flashing from PK1 to PG1... My phone getting hot after PK1 update. Please help.....

 

[silversusanoo]

Any luck?

Getting the same Error while flashing from PK1 to PG1... My phone getting hot after PK1 update. Please help.....

I need help with the G930TUVU4APK1 update as well. I can flash the TAR file, but I cannot run the root files.

 

[sabresfan]

I need help with the G930TUVU4APK1 update as well. I can flash the TAR file, but I cannot run the root files.

I just rooted mine this morning. I played around with it a few times. What worked for me was run root.bat with my phone unplugged then plug it in. It took a few minutes for everything to go through. Hope this helps.
