Root [ROM][MetroPCS & T-Mobile] Katana ROM *Updated 11-16-2015*

[CYCONUMNUM]

GT probably did what any of us would if we could....
throw it because we could afford better..I dunno...
I dig the styling ..and the cut out in the back of my case looks a bird's eye view of a land speeder

@CYCONUMNUM

If you have the update notification showing on your lock screen.....

Or showing in your desktop pull-down notifications..... press and hold, wait for it to turn into app button..

Click on the info button... it will go to another screen...

Then check "none" (show no notifications from this app)...

You'll never see it again [emoji6]

ty for your help..it is appreciated

Could Katana Rom be ported or made to work on Lg Leon by using text editor? If so may i have your permission to do so?

May i port katana rom to my lg leon? Please.

What you do with your phone is your business. Just don't expect GT to be cool with you sharing it with others. He doesn't like people using his ROMs/kernels in their projects.

It sounds as if you're asking if changing a couple of prop files will make this ROM work on a LG Leon... and no it won't. The Stylo and Leon are two completely different phones with no matching hardware.

 

[Izzxy]

Two questions is the kernel flash able to the stock 5.1.1 and is there a way to remove or change the battery icon

 

[JaronH]

Anybody knows if this is safe to flash on Marshmallow? Will I have to go back to stock 5.1.1 to do this?

This is exactly what I was wondering. I'm on stock mm metro with root and twrp. unlocked bootloader. can I flash back n forth between my backup and this rom? Will it mess up my phone trying to do so since katana is lp and I'm on MM? Any help in answering this would be greatly appreciated. Thanks guys!

 

[viperdink]

I have. it works no problem. I've even restored a nandroid back to katana after wiping all partitions but extsd. Yes its backward compatable.

Already did it. Nothing adverse happened, here. Just follow the directions GameTheory gave, and you'll be fine.

 

[CYCONUMNUM]

Only Rom that got my phone all wonky was cm...got the half black screen thing...
Other than that...2days ago i flashed to the "skinny" t-mo Rom..only to find out its not that skinny...but, has a purdy boot ani...
Then saw the radio OTA..flashed to metro mm....then ......decided i was'nt into possibly going for a loop...
And re-flashed t-mo "skinny" after i found a flashable de-bloat for t-mo in the evil forest of xda....
Then threw my usually redundant paint job at it....
Works cool..i modded the sound mod flash down to 95...99 is pure cruchy caacaa for sound values..
Yah

The splash screen did indicate the boot loader being unlocked till I unbricked the device with kdz a file.

@GameTheory
Or Anyone?
How did you disable LG Root Check tool?

I still like katana . I just can't get a metro browser to stay stable. It works for a while then I have to go back to chrome which I don't care for. It just gets slower and slower till it freezes up. Then i just wipe the cash again. I've tried all I can think of. Any body got any ideas.

Is katana better in overall performance than MM? Im thinking of trying katana but to trade it for 6.0.1 permissions plus video calling and multi-window support, is it worth it? Any feedback would help thanks.

You will lose the permissions (you'll probably find a way around that) and video calling, but multi-window support has been on the Stylo before MM. Plus, with Katana, multi-window works on ALL apps. [emoji2]

I did the same thing switching from MM to Katana. The performance is a lot better in comparison. Too bad GameTheory hasn't been around for a while, we could've had this upgraded to MM.

Katana is my favorite.
You can't go wrong with it.

On my LGM631 this ROM just boots to TWRP. Follow directions to the tee. Factory reset, install kernel, than partitions. Tried various other ways too, no matter what it boots to twrp and fails. MM 5.1.1 10j here.

If you can't get Katana to boot properly, you should learn how to flash the stock ROM for Lollipop on the LG G Stylo and try again, making sure to get TWRP reinstalled.

Sorry not MM I meant Lollipop 5.1.1. That's what I did, from Stock 10j. Isn't my first rodeo. Only my 45th phone. This phone has only ever been on stock 10i and 10j

If that is also the case, it should be written in the directions for others having issues with it as well.

If all you say is correct, then use this and start again.

 

[WASaaquatch]

Still the same issue guys.

1. Downloaded TWRP 2.8.7.0-10j
2. Install TWRP with flashify (to be sure it was right version)
3. Install bootstack
4. install return2stock
5. Wipe dalvik/cache
6. Reboot
7. Root
8. Install TWRP again
9. Format Data
10. Type yes
11. Install Katana ROM
12. Install LGMS631 Partition
13. Reboot
14. Loads for about a minute with LG logo
15. Reboots
16. Loads for a second with LG logo
17. Boots into TWRP
18. Gets frustrated and tries a different approach
19. Install bootstack
20. Install return2stock
21. Wipe dalvik/cache
22. Format Data
23. Yes again
24. Install Katana ROM
25. Install LGMS631 Partition
26. Reboot
27. The reboot to TWRP continues...

I guess I am stuck with the stock ROM. Wish there was more done with the Stylo, it's a good phone IMO.

If it's any diff, my phone was manufactured in 2016 after this ROM.

Reason I wanted this ROM is to try and stop MetroPCS from medelling. They are able to trun off both PDANet and Hotspot at any point. I pretty much can't do anything without issues. Even using a VPN will disconnect at random points, followed by the hotspot/pdanet. After a phonecall complaining about 1.5GB of hotspot data used before I even had my phone on when my cycle renued they changed my net to ALWAYS display a Android user-agent, overriding any custom string or default I use on my computers or phone, effectively breaking a good portion of the net for me. This I know I probably can't fix with a new ROM but was hoping the MetroPCS triggers that turn off the hotspot and such would be gone.
