About
Undine-X is my customized Kernel for Wingtech wt88047 a.k.a Xiaomi Redmi 2 with lots of new features.

I'm just test on cm13 and aokp only. but you can try it.
don't forget to backup boot partition before flash it.

Thanks for review
imo it's not really "cant reach",
but it optimized so cpu load is still under 1.4ghz.
Performance governor ramp up your CPU at the highest value, it doesn't matter were you are in game or just playing music.

Thanks イチハラ リファ(Katakana lol) for implementing dt2w. I find it interesting on how you implementing fastcharging in your kernel and wonder does the charging stay at a consistent rate of 1500mA ? Can anyone test it out?

it depend on hardware, i mean i'm just trying to combine usb fstchg patch with more value at max volt.
well i'm still not tried about it because i dont have tc adaptor that larger than 1000mA :laugh:
lol my english is very bad :laugh:

Good to see the development of redmi 2 now.
Kernels are coming like rain!
Development like this seems unbelievable!

Well I used the Ampere app, the max.amount of current I got was 1010mAh , with constant values revolving around 700-800mAh. Others can also check. I'm using the stock charger.

After install the kernel I can't unlock my phone, I'm using pattern unlock. Everytime that I try to unlock a black screen appears and go back to unlock screen.
I had the same problem with latest version of octopus kenel and I have to use and old version.
Any idea how to fix this problem?

I will look into that,
temporary, you can disable dt2w.

Yup... dt2w is the one causing this problem... the touchscreen doesnt seem to wakeup from touch inputs

Update X1.1-2-H20 [new compiler and hotplug]
Changelogs at first page :laugh:
Ayy my minus is now increased, lmao

---

no kernel-bugs-related so far....
[i'm more than a noob when it comes to kernel]
this is the only one that made my 紅米2 react properly on dt2w
(feature i missed the most, and coming back big style) {still waiting for a stable berserk to be honest}
8 stars (out of 5) for the looks/user/aroma approach - specially for people not using kernel managers (i'm not 1 of those, but solidarity is important)
has every other "crowd pleasers" working except for control freaks (just kidding) + screen/color profiles << this is not a plea
++ having an option for color-profile would imho make it more than awsome......
great work, even greater kernel, thank you
tipsy by @premaca
recommended settings more than appreciated
