Does dumb-ass (aka KennyG123) actually comprehend what “off-site” means? Fuck no !!
Still a tonne of stuff to do. Some thing I like not working yet. But this is much better and “cleaner” than earlier builds. Suppose it’s only been 1.5 years ! 😆 I haven’t tested LTE either, I don’t use a SIM.
OK this mm rom is it available on xda very interested in testing I have t805y and t705y currently on mm bootloader but running sweet rom at 5.0.1 found knox on 6.0.1 a bit of a problem……
I’m sorry, I only have a T705 exynos5420 and only intend to share my personal build for that. This device is just way too old to invest further support, since I already support 17x other device variants. I am not ‘robot’ 😉
Need to tidy up tomorrow. Will share after then, maybe next day? Not sure. Have not tested everything, and one feature needs fixing in Synapse. Might leave it for another time and just temp disable it from page layout. Made a few commits and optimizations today, so also need to give things a whirl !!
This sounds nice. I’ve been using your kernel on my T700, when you were still using XDA as place to share your projects. It’s not like I’m rushing to use a custom kernel, I don’t have enough knowledge to use it to its full potential..Still I’m fascinated by your work and would be cool to test it. So in case you would ever think about releasing it,here’s a tester :p .
Well done anyway, our tablets still run strong
As in the title “T705 Exynos5420 ” . You won’t be able to flash it on other, and if manged, many settings, defaults and Synapse support will be disabled.
Okay, I’ll try give support to the SM-T700 Exynos5420 variant. Uses exactly same drivers (minus) modem and some sensor changes etc. The source will always be based on T705 though, I’ll just use variant specific ramdisks. If you have issues, afraid that will be just “tuff luck”. Getting real close to first public share. Having major PC corruption and boot issues. I think it’s on its way out.
Well. I’m actually ready to build, and with just one feature that’s not working. BUT. PC is dying…… Managed to save my work, but unable to boot or complie. Once in a while I’m able to boot, but the HDD makes ticking noises. Huge slowdown and read errors. Loads of corruption. Think the issue is caused from hardware > OS corruption…. hopefully get it booted again to complete the builds
Finally managed to build for both SM-T700 / SM-T705 variants. For use with STOCK TW based firmwares. Please ensure you delete any ROM cook bullshit “tweaking” from various places ie. init.d build.prop and remove any other kernel or CPU control apps !!
Will update the very first post when I am able. Currently having major PC issues…..
Linaro 6.2.1 + Linux 3.4.113 + many selective optimizations + Synapse + Aroma
Just got PC back up and running. Had to go buy a new HDD and setup everything from scratch.
Anyway. there are a few Synapse BUGS to sort out.
1 – enabling cortex-brain will cause lock with “sed” and freeze Synapse and causing CPU stuck at max. Please do not enable this. If you have, then please force close it and wipe Synapse data. then reboot !
Well, some more good news. I’ve managed to fix cortexbrain + crontab + merged new source !! A little time to test overnight, and I’ll test again tomorrow with updated ramdisk for T705 🙂
Need some rest after frigging with the PC all day. I expect the tests to have no issues, so expect to update tomorrow night.
Didn’t test crontab but noticed the cortex issue. Nice to hear you’ve already fixed it. Couldn’t play with settings today but seems everything is working flawlessly on my t700.1 question though, are the tweaks in the cortex tab affected by the cortex master switch itself or do they work on their own? Anyway as always, nice work!
I’m really happy seeing the far best kernel and developer supporting the Tab S family one more time 🙂
Even that unfortunately i cant test it because i have a T800, I’m very happy about it!
I still on TW 5.0.2 for one simple reason, i love your kernel. Realiabre, feature rich and make my tab s fly 😉
Best wishes for you, hope you keep the great work, and good luck with your pc!
Kernel seems running nicely. Didn’t encounter any issue so far. Very well done. Will throw a small donation as soon as I load some euros on my paypal!

Just a couple things I found in Synapse to take care of. Noticed when I diff some scripts between my 7420 and 5420 scripts. Nothing “serious” to worry about. But I’ll still sort it out….. eventually.
wondering if anyone has tried this with ironrom,(with ironstock)…willing to give it a go,and i could have sent you a hdd(have plenty laying around)…thanks for your hard work
Perhaps you were previously rooted and or with another root method. This is all really easy…..
1. Flash stock firmware
2. Flash TWRP
3. Flash kernel
4. No need to wipe anything. Just reboot system…
More than likely something left on your data partition that cause issue, but a previously modified system also. Definitely not the kernel. How on else did I flash it…. same as state above.
User responsible to backup their own data and common sense dictates copy it off device.
If the above doesn’t work. Then full wipe system, data, dalvik-ART and flash full stock as described above. Will sure be fine.
Also states which ramdisk base is used. That indicates which firmware I’m using, so could be incompatible with newer firmware. There is no newer source.
I’ll only be using it with whatever Thai firmware is released. There is a tonne more to do on kernel and ramdisk and synapse, as well as build script. There is no more “development” except for compatibility with my own firmware. I don’t build for XDA. They are just ungrateful “children”. If rather let SkyHigh become a has been. Same I’m stopping Exynos7420 development and not gonna publish my latest update. I’d rather no one have it than let those theiving shit-stain Tkg “super stealing” kernel rip my copyright material, remove legal licence, republish and modify and without permission of the original author == me ! But hey, he does have a “recognised PoS” tittle for “his” efforts and contributions
There is no Headphone volume control, just speaker volume control ……. so why would it work when there is no control? However, you may adjust headphone equaliser band gains, and that definitely works. If it doesn’t on yours, you have messed up your stock ROM.
Sorry my mistake it was earpiece .
If your planning for next update that if possible to add RGB color control in screen section (RGB,SATURATION, HUE,CONTRAST, COLOR TEMPERATURE OR GAMMA)
and headphone volume gain or hd audio codec.
