[RELEASE] ShinTo Kernel v31a001

Welcome to the current official release of the ShinTo Kernel series.

shindo

Please always get the latest release from HERE

Why name the Kernel “ShinTo”?

To me it has the meaning of “Study of the Essence” (to achieve) “The Way of The Gods” as, to me, ShinTo Kernel is a way to learn and become an expert.
Also the name just sounds very “catchy” 🙂

!!!PLEASE READ AS CHANGES ARE EXTENSIVE!!!

More information of the origins of ShinTo Kernel can be found in previous version posts.

How to install ShinTo Kernel?

  1. First CREATE A BACKUP OF YOUR ROM (in case something awful happens and you need to restore)!
  2. Did you create the backup in recovery?
  3. Go to recovery mode (Power off phone / Once powered off, press PWR + HOME + UP VOL).
  4. Once inside recovery (tested with TWRP 2.8.1.0) you select install and choose the .ZIP that you have previously downloaded from here.
  5. Once installed, reboot into normal mode and wait for the phone to come up.

One thing you will notice right out of the bat is that the led starts to blink in different colors and brightness; that’s ShadowLED working for ya 😉

How to UNinstall ShinTo Kernel?

  1. Flash any other kernel you would like on top of ShinTo Kernel.
    ShinTo kernel uses it’s own unique and private “init.d” so from this version on, it won’t touch  /system/etc/init.d anymore.
    All options can be enabled/disabled in Synapse and the settings survive a flash, reflash & even a format, backup, restore, etc…

Alternatively you can recover the backup of your rom if you messed something up.

How to go from EXT4 to F2FS & vice versa?

ShinTo Kernel includes a new and much improved clever code at bootup that takes care of a couple of things for you, so you can test F2FS in any combination you see fit, and even go back to EXT4 if you don’t like F2FS without loosing any data but you have to follow some logical steps detailed here by the great Megaflop666:

  1. Update TWRP to the latest and greatest 2.8.1.0, you can download it from http://teamw.in/project/twrp2
  2. Drop to TWRP and flash the latest Shinto Kernel ShuriKen
  3. Reboot and let the phone fully boot up and settle down, give it 15 minutes
  4. Open Synapse and make sure all settings are stock, if it tells you that your previous settings cannot be used, click “Understood“, and then click the apply check mark at the top.
  5. Go into ES File Explorer or something of your choice and get ALL USER DATA THAT YOU WISH TO KEEP off of the internal SD card.
  6. IF YOU MISSED IT BY NOT READING #5, YOU WILL LOSE ALL PERSONAL DATA ON YOUR INTERNAL STORAGE BY DOING THIS (as TWRP doesn’t back that part up)!
  7. Drop to TWRP and run a FULL NANDROID BACKUP to your External SD Card.
  8. Go to SETTINGS and unselect (un tick) “use rm -rf instead of formatting” (We want TWRP to actually format with f2fs)
  9. Go to Wipe and Choose Advanced Wipe
  10. Select System and choose change or repair file system
  11. Choose f2fs and go through the steps where it tells you that all data will be lost and apply it.
  12. Follow steps 9-11 for Data and Cache one at a time.
  13. Go to SETTINGS and select (tick) “use rm -rf instead of formatting” (We don’t want TWRP to restore back to EXT4)
  14. Do a restore, but ONLY CHECK SYSTEM & DATA for restoral, NOTHING ELSE IS NEEDED.
  15. It will tell you that your backup was made with ext4 and may not boot, don’t worry it will boot.
  16. After restore, reboot your device. First boot will take a few because it’s a new file system and your apps will have to reconfigure themselves, etc.

You can see what partitions are in what format if you go to the i/o VM tab in Synapse. 

 

On what models does ShinTo Kernel work?

For the time being, it has been confirmed to run very fast & stable on the Samsung Galaxy Note 3 SM-N9005 (international SnapDragon) and on N900T (TMO T-Mobile USA), on any Samsung TouchWiz rom.
It is only meant to work on Samsung TouchWiz roms, for now… 😉

    hey man THANKS A LOT! with the other version my phone wan’t boot up, now boot and i can try your kernel!

    high five from italy

    • iamskynet says:

      Grazie, il mio piacere!

      Hope you’ll like it and it will perform well for you.
      CIAO!

      • BryanD says:

        you are AMAZING!!! your kernel work really perfectly! it’s incredible becouse i have tried about 7 kernel’s but they aren’t work how i like! and i find your kernel becouse an guy’s talk about on xda but i don’t never an post, and i think people need to say what fantastic job you have do!

        i have the last question’s, there is an FAQ for various kernel setting (or what you like for performance/battery), becouse i think it’s important for guys not have familiarity with kernel settings!

        CIAO!! 😀

        • iamskynet says:

          Grazzie for such nice and encouraging words.

          I don’t have a specific faq setting as I am constantly changing stuff and flashing to test.
          It all depends on what you want to achieve, if more battery life or more fluidity or a balance.
          I recommend you do a backup of your phone and okay with different settings.
          Enjoy!

      • BryanD says:

        Ok man i have too much to work!

        i have some question for you (ideas for kernel and other) but for don’t write here too much i want talk with you in ptv, it’s possible? (i dont have twitter haha)

  2. mat9v says:

    I wonder, why exactly the minimum frequency for gpu seems to be 320mhz? I can’t set it lower in Synapse. Changing USB mode from UMS (that I had set on earlier kernel) to MTP results in error “SOptionList has failed – device or resource busy” – irrespectively of the usb cable being connected. Nevertheless usb state was changed to MTP. Now I can’t change it back to UMS. I have 2 original Samsung chargers and I have set charging speed to 2100mA in Synapse, with ignoring dangers and so on, but unfortunately it does not work and still tops up at 1800mA (as Galaxy Charging Current informs me and charging log confirms). Same happens on both chargers (different cables too).

    • iamskynet says:

      Gpu drops to 200Mhz in reality but you see it reflected as 320.

      Thank you for reporting the Synapse problem with ums setting. Close Synapse and try again to change it back.

      When you set up 2100 as maximum charging current that current won’t be effective until the screen is off. When screen is on the charging current will be 1800 mA as per every single kernel out there. Charging current can also be affected by the quality of the USB cable.
      Try the following : load GCC, turn the screen off. Wait about two or three minutes and then turn screen on and immediately refresh GCC. What do you see as charging current?

      • mat9v says:

        OK on GPU. Closing Synapse, restarting the phone and resetting Synapse data did not help. As to the charging – I meant whole charging cycle from about 10% up to about 90% as reported in charging log – it measures charging rate and writes the result every 5 minutes . GCC was only for verification in the middle of charging process – turn the screen on, unlock, start GCC (from killed state) and check. It’s not that I’m very bothered by this as the difference would be less than 20% anyway but I like to have stuff working as they should. It’s a bit disappointing really, I had Note 2 and when connected to my PC usb port I could charge it at 1500-1700mA and now in the same port (though the cable is USB 3 and not USB 2 variety) I get less then 1000mA, changing cable to the old USB 2 does not change the charging speed anyway.

        • iamskynet says:

          The Synapse USB MODE happens in my case when I select PTP, but when I exit synapse and load it again I can select other options.
          Will check “Charging log app” to see if I have the same results.

          As per the disappointment, you can always uninstall ShinTo Kernel, install a kernel that works for you and be happy with it.

  3. mat9v says:

    Nah, you misunderstand 🙂 I never got the charging speed to go higher than 1800 on any kernel nor did I ever get more than about 1000mA from my usb port on any kernel – it seems that the way they are all written it just isn’t possible – though on Note 2 it worked fine. It was a wishfull thinking on my part. I would not uninstall ShinTo kernel as it is superior to any other I tried in any way that I can test 🙂 So don’t worry, you have a convert in me. I will test USB mode further later.

    • iamskynet says:

      Are you empirically sure it is not working?
      If so, then I will have to look into the inherited code and do my own assessment as I also like my battery to charge as fast as possible… Am not too worried about it’s lifespan as I can buy a new one for 10e.

      I’ll make some time now to do a log run and collect information from the charging process and see what are the real values as reported by the charging chip.
      Would like to get to the bottom of this…

      So, I did a test run and collected the info from system log (/proc/kmsg).
      Data here is filtered with grep for Inow.
      From the data that the managing chip is spewing out, it seems to be charging with 2.100mA in my case…

  4. mat9v says:

    I stand somwhat corrected 🙂 I have looked through a log and Imax is correctly set to 2100, only Inow is rarely that number, it varies from 1000 to 2100. I have not checked kmsg before and relied on Battery Monitor Widget Pro history log – it shows values sampled in intervals and averaged on 5 minutes basis – the max that it ever showed me (checked over 2 months worth of data) was 1768mA. It seems that my chargers are not up to snuff or… I don’t know what. Nothing wrong on the kernel side since it sets 2100 correctly.
    Is it possible to increase charging rate for USB 3 connector in PC? Mine can handle 1500+, tested for over a year on my Note 2 and I prefer charging out of PC.
    Have you ever tried to actually OC GPU in our Snapdragon? I have read reports that it does not work and I have never had any gains in performance on other kernels that had that option. Is it possible to do or the hardware is factory limited?

    • iamskynet says:

      Will look into the USB3 thing, but right now I’m severely strapped for time.

      The only way to be 100% sure of the mA that the charging chip is requesting and getting delivered would be to use a measuring station that you plug the phone to, and it would give you all the data in real time… I think some time ago I saw a gadget of the sorts in DX (DealExtreme) that you would plug between the phone’s usb port and the charger.

      I’ve worked extensively on the GPU part and I came to the same conclusion as you.
      I bet it’s on the FW side that must be hardcoded for the Adreno 330… the gut feeling is that anything above 487 gets cut to 320…
      I did increase the backend bus for the gpu (which it seems no one bothered to analyse?) so that might help…

  5. Ernigeek says:

    I just need to do this for some reason… honestly I don’t really know at all why:D
    YOUR KERNEL IS AWESOME!!!!!!!! It gets updated frequently, it has all the mods and tweaks that are important while having some tweaks (or should I call them revolutionary features?) that make this kernel unique:D the precognition gov is something really good that I have not seen on any other note 3/Nexus kernels:D This governor is awesome! Pls keep up the good work since right know your kernel is the very best available hence i will defientely miss you support and features when swithing devices:D
    anyway thanks again for developing such a great kernel, for sharing it and for implementing features that really make differences!!!

    • iamskynet says:

      I thank you for such encouraging and kind words!
      Just be warned that PrecoGov is still in very ALPHA stage and a lot of things are not yet implemented. I mean it is just dealing with about 15% of the stuff it should be, so it is not the best choice for every workload out there and it will drain more battery.

      Some ppl don’t read and keep pounding me with that, so most probably PrecoGov will be taken out of the next release.

      Hence why your words are encouraging 🙂

      • Ernigeek says:

        Maybe it’s just me but most of the other governors are causing my note 3 to overheat when playing casual games… (except ondemandplus)while my it is just doing fine with the precog governor:D
        But there are two questions left:
        1. your prev. aswer seems to imply that i could even better performance and battery life with different governors… do you have any suggestions? I already checked several release notes but I did not find any direct suggestion regarding the governor.
        2. where does that name come from? Was it once an insider joke or something like that? would be very interesting to know!:)
        Thanks for your quick response (previous one)

        • iamskynet says:

          Well no I don’t have any specific recommendations because I haven’t found a governor that adapts to all the different workloads and most of the “exotic” ones are basically a copy of conservative with varying degrees of added code / ideas / tweaks that revolve around the same old principle.
          PrecoGov aims at flipping the problem around by infusing (real) intelligence into it (not even 5% there for now) and adapting precisely to the Note3 ”s owner.
          Who knows maybe I will succeed or maybe I will crash and burn, but either way it’s a great way to learn C for Kernel.

          PrecoGov comes from Precognition Governor and the name of PreCog.me comes from a time ago when I did some hacking to improve the response time and I name it “Precognition UltraBoost”

          It has to do in a way with AI and robotics 😉

  6. Ernigeek says:

    Well, very interesting to know where the precognition governor’s name comes from but that wasn’t the name explanation I intended to ask for… (I read my comment again and I noticed: well, you did not tell which name you want to have explained:D *facepalm* sry:) )
    Actually I was interestedI where the name ShinTo comes from….
    (sry for my misleading prev. comment:/)

    • iamskynet says:

      It is explained at the beginning of every ShinTo Kernel post, the where & the why.

      • Ernigeek says:

        I swear I read the content of this site several times but I somehow did not notice your little info part at the very beginning…. I must have been toooo excited:D but unfortunately that’s where misunderstandings and mistakes come from:(

  7. mat9v says:

    I’m using Precog governor and it works great, battery life is incredible – I get 16 hours of SOT on standard battery (granted it’s mostly reading documents in pdf or on the intraweb but still…) over 2-3 days. If anyone does not believe I can send them screenshots 🙂
    However it does it, this kernel just wakes the phone the moment I press the home or power button – almost no wait time like I had on other kernels. I love the leds reporting activity for accessing memory and internet. The only (very small) problem is in some games that occasionally stutter for few seconds but it have more to do with my temperature limits (65C for core) then precog config 🙂
    All in all – Great Work !!

    • iamskynet says:

      Thx.
      Ocasional stutter in games can be PrecoGov getting confused when you go from say 1 or 2 cores to 4 cores then the load gets spread evenly so it thinks the phone is less busy and tried to scale down to save battery.
      That will change in the future by doing things in a very different way… 😉

  8. mat9v says:

    No, that’s not it – it’s like the game for 3-5 seconds decides to play with 10-15 fps while at other time it works fine. But I tested it out in the last few hours and it is thermal related. All other things being constant, once I incresed max temp back to 85C the stutters were gone. The phone is much hotter but the game works smooth. If you want to test it, its Eufloria HD (HD version is only available from HumbleBundle so I would have to send it to you) – great game on it’s own 🙂
