I'm using your latest rom with klx18 kernel, and I'm very happy with it. Nice performance and nice battery life.

I'm about to flash the latest kl19... What's your insight when comparing these 2 kernels?

Klx18 is OCed, so one would expect a snappier system than with kl19, right?

Or the new optimizations in kl19 would bring it cost to klx18 performance?

And to flash kernel... Wipe cache and dalvik? Or something else?

Thanks in advance
[Shield Tablet Android Development] BitOBSessiOn:
I prefer KL-019 over KLX-018. Performance is not only

MHz... Anyway, probably, a new KLX with these optimizations will come...

I recommend wiping cache and dalvik after flashing.
[Shield Tablet Android Development] MarceloSiciliano:
BitOB when voltage control is coming? Voltage control is awesome for saving battery
[Shield Tablet Android Development] BitOBSessiOn:
No ETA... First of all I have to learn how to... ;)
[Shield Tablet Android Development] Pariahnoble:
I've had some real issues with the new update....019 caused lock screen touch death on aicp, bootloop on bliss, 017 seems to be just fine though, 12.1 kl on both

---------- Post added at 03:13 PM ---------- Previous post was at 03:07 PM ----------

Edit: lock screen was ROM based on aicp I stumbled upon a dev build that wasn't done yet. Not sure yet what the issue with bliss was. Only thing I changed was TCP to high-speed with kernel adiutor. Maybe that was it... I gotta start logging for ya. As much as I tinker and flash this thing. What should I use that I can get the logs AFTER I recover or re flash?
[Shield Tablet Android Development] BitOBSessiOn:
Ummhh... Wich package do you use? which rom...?
[Shield Tablet Android Development] Son-j:
Hey BiT, do you think there's a serious issue with KX10-3?
[Shield Tablet Android Development] filjusz:
I dont have this problem, try older version which is still better than stock
[Shield Tablet Android Development] Both Barrelz:
So this is what's happening with my device. Since reverting back to stock from KX10. It charges incredibly slowly and discharges with light use when using whilst on charge, even with display on the lowest brightness. Turning off the device and charging seems to charge faster but still slow (charged from 50% to 70% in about an hour and a half.) Trying to boot whilst on charge will result in a bootloop, showing boot screen and then charge screen.Will boot fine as long as not plugged in. I'm guessing something has been left behind after reverting to stock kernel. I'm going to flash stock again and see if that helps.
[Shield Tablet Android Development] filjusz:
This is typical known issue for people that not updated bootloader to "M" one.
[Shield Tablet Android Development] Both Barrelz:
I'm running stock nougat.
[Shield Tablet Android Development] Baldyshugga:
So where can I get stock kernel for Nougat? I'm having issues with adaway since flashing this kernel. It won't keep it's settings.
[Shield Tablet Android Development] Both Barrelz:
Did you make system writable? Adaway won't work on nougat unless you do.

---------- Post added at 09:34 PM ---------- Previous post was at 09:31 PM ----------

Also. Re-flashing Nougat seems to have solved my problems. Boots fine and charges as expected. Phhhheww. Was worried I had naffed my battery.
[Shield Tablet Android Development] Baldyshugga:
How do you mean?
[Shield Tablet Android Development] Both Barrelz:
Nougat by default has system set to unwritable. You need to change it to writable. If you haven't, then that will be the reason adaway is not working correctly. It shouldn't even let you apply the adblock and come back failed when you try to be honest, unless system partition is set to writable.

---------- Post added at 10:06 PM ---------- Previous post was at 10:01 PM ----------

Look it up with Google. It's not hard to do and only takes a few minutes. You will need busybox installed and a terminal emulator. Both are free to download from the play store. If you need to be pointed in the right direction then PM me.
[Shield Tablet Android Development] Baldyshugga:
Adaway works when applied but reverts after reboot. It worked as normal before installing this kernel. Explanation for that?
[Shield Tablet Android Development] Both Barrelz:
Like I said if you haven't got system partition set as writable it would never have been working in the first place. Adaway needs system as writable. Fact!

Unless of course you have downloaded an altered stock 7.0 rom or are running a custom rom which already have system partition set as writable.
[Shield Tablet Android Development] Baldyshugga:
No I'm using the stock Nougat Rom. Adaway worked just fine before installing KX10 kernel. Now whenever I restart my tablet it will revert back to the original host file. So Adaway is writing a new host file but restarting reverts it.
[Shield Tablet Android Development] Both Barrelz:
Just type 'adaway nougat' in to Google and you will see what I mean. There is no way that adaway was working for you even if it somehow said it was. Nougat is designed to have it's system partition locked, an added safety feature to 7.0. Adaway cant work with an unwritable partition, it just cant.
[Shield Tablet Android Development] Baldyshugga:
I am very well aware how adaway works. Not my first time using it. I've used it since LP. So I know when it's blocking ads in chrome and most all other apps. So your theory is mistaken. Unless you have had my tablet in your hands using it then you can't say you know it wasn't working before the install of the kernel.
[Shield Tablet Android Development] Exile1975:
If you're using the latest version of adaway, have you checked that the systemless option is selected? If it isn't then your system will just revert to the hosts file saved in the vendor partition....
[Shield Tablet Android Development] drewski_1:
ad away needs root to work, and it can also run Systemless
[Shield Tablet Android Development] Both Barrelz:
I was using an outdated version of Adaway and had to use an old school workaround. Didn't realise that it could now run systemless, my bad.
[Shield Tablet Android Development] Baldyshugga:
Yes systemless is checked.
[Shield Tablet Android Development] BitOBSessiOn:
About charging issues... KX10-003 has some thermal params tweaked, so you can get this kind of issues... DTB values changes in KX so it's totally expectable.

As many of you know, OC is not a priority for me. I consider that ST's CPU/GPU is fast enough for gaming and I prefer to be focused on global system performance and smoothness (stability, latest linux kernel source, F2FS, CPU mangament, cache and architecture tweaks, etc...). I add OC because you ask for it, but all OC dev is not mine, as you know.

For those who have battery calibration issues I would suggest to try to be in a coherent scenario (DTB byt bootloader and kernel version) and recalibrate it (let battery drop to 0%, and charge until 100%).

If there are people with issues and people with no issues, we need to know current scenario for each one (kernel, latest flashed stock version, using or not custom DTB, etc...), but I'm afraid that probably I'm not going to help much here (KX)... sorry.

My recommendation is... keep sticked to K series for stability and no head aches, flash KX only if you're a brave soul and at your own risk (battery issues, CPU burnout, dead kittens, etc...).

To meditate about:

Do you notice much difference between K10-002 and KX10-002...? (K vs KX)

Do you notice much difference between KX10-002 and KX10-003....?

Does it worth ... ?

You tell me, because I don't use KX, I only flash it for smoke testing.

We talk. Thx !
[Shield Tablet Android Development] Baldyshugga:
Ok I reinstalled the kernel and the problem seems to have gone away. Now if I could only figure out to mount a LAN drive through Cifs.
[Shield Tablet Android Development] f0xG3:
Hi Everyone,

May I ask if this setup is possible :

1. F2FS Cache and Data

2. I use my SD card as Adopted storage, it will be EXT4 presumably. I can still keep the F2FS internal storage and cache or this kind of thing is not possible.

3. In order to make use of F2FS Data and Cache, I need a ROM that supports this right? Or can I keep my stock nVIDIA ROM?

Thanks :)
[Shield Tablet Android Development] Bryanx86:
Yes, it's what I've done on my shield and I think is the intention of bitObsession's f2fs TWRP. I flashed carbon rom after formatting data and cache to f2fs, flashed the f2fs boot injector and kx10-001, with magisk and f2fs is definitely noticeably an improvement, thank you [MENTION=6411851]BitOBSessiOn[/MENTION]. I believe it is intended to be used on stock 5.0 update and later
[Shield Tablet Android Development] Paolo ponzano:
Does magisk and magiskSU work with this kernel?
[Shield Tablet Android Development] filjusz:
Yep
[Shield Tablet Android Development] f0xG3:
---------- Post added at 01:26 PM ---------- Previous post was at 01:25 PM ----------

[/COLOR]

Have you tried using an SD Card as Adopted Storage?

While this will probably be EXT4. Did it had any issues with apps accessing app resources found on the SD card? (due to the system thinking the SD card is... extra storage)
[Shield Tablet Android Development] Bryanx86:
Using sdcard as adoptable storage has always been too slow for me, i only use it as portable storage, but i have nothing on my card so I will try and report back.
[Shield Tablet Android Development] Bryanx86:
Yes you can use as internal storage on aospex and it formats it f2fs:svetius:
[Shield Tablet Android Development] BitOBSessiOn:
Are you using AOSP Extended for Shield Tablet... ? Which build... ?
[Shield Tablet Android Development] Baldyshugga:
Is there any way to add Cifs support to this kennel?
[Shield Tablet Android Development] Bryanx86:
This one, on my pyro tab
[Shield Tablet Android Development] drewski_1:
I was getting big lags on wake using kx10-003, like 15 seconds from Power press to screen on.

no issue after going back to 10-002

---------- Post added at 10:49 PM ---------- Previous post was at 10:48 PM ----------

where do you find the AOSP extended​?
[Shield Tablet Android Development] Bryanx86:
Go to Android file host, and type in shield, shield tablet zips will come up. I do it with my 6p and find crazy stuff all the time, lol
[Shield Tablet Android Development] BitOBSessiOn:
Dou you mean this...

https://www.androidfilehost.com/?fid=673368273298953832

...built by me or another version from any other dev ?
[Shield Tablet Android Development] Bryanx86:
was built by you, runs very smooth with your kx-001 kernel. I couldn't get it to boot with 002, or 003,b
[Shield Tablet Android Development] drewski_1:
i just did a clean install with 002 and it booted up AOK :eek:
[Shield Tablet Android Development] Bryanx86:
hmm, how long did it take? maybe I didn't wait long enough, do you use magisk?
[Shield Tablet Android Development] drewski_1:
SuperSU 2.79 beta3

Not sure exactly how long. 5-7 min? Seemed pretty typical for a clean flash
[Shield Tablet Android Development] primaleph:
Some more info on why this might be helpful for further improving performance, copied and pasted from the Crossbreeder Lite page:

"CrossBreeder now supports linking both your random devices to the extremely fast alternative - Frandom. This module is orders of magnitude (10-50 times) faster than the standard character devices ( Check this out ). The erandom character device also installed by Frandom doesn't use up system entropy at all on top of being fast. You will need to ask your ROM developer to develop the kernel module for you and then place it in /system/lib/modules. CrossBreeder will then try and load it and if successful, make all the necessary adjustments so that both /dev/random and /dev/urandom are pointing to /dev/frandom and /dev/erandom respectively. The speed benefits are to be seen to be believed. But since each ROM requires a unique kernel module, this option is left optional ( but auto detect ). "

I'm not a developer myself, but I've been in tech support for 20+ years. Seems to me if you were able to build frandom for this kernel at least for testing, and then set /dev/random and /dev/urandom to point to it as above, it might be an easy way to speed up the kernel even more.
[Shield Tablet Android Development] drewski_1:
Sorry for the OT, but I'm finally getting Deep Sleep with your AOSP-EX ROM. :victory:
[Shield Tablet Android Development] primaleph:
Are you able to play video on it in Youtube or Netflix? I've been unable to on any other Nougat rom based on AOSP.
[Shield Tablet Android Development] drewski_1:
YouTube works. Not sure about Netflix
[Shield Tablet Android Development] primaleph:
Thanks, good to know.

I'm also concerned about Tegra games such as Granny Smith and Bladeslinger. So far I've only been able to get them to run on stock.
[Shield Tablet Android Development] LiamAtkins90:
I have a question guys, does GeForce Now work on custom ROMs? I have the new 2017 controller so I assume connecting it over Bluetooth wouldn't be an issue. Thanks.
[Shield Tablet Android Development] drewski_1:
Just tried . Neither of them work. They load, but don't play.

Bladslinger had a message about missing native libraries.

im running CM13 20160820 6.0.1. MOB30Z and im wondering which kernel version is the latest and most stable for my build
[Shield Tablet Android Development] Blu3Rog3rs:
Hello,

Im trying instal on recovery mode zip files for the kernel and i cannot because says:

e: footer is wrong

e:signature verification failed

instalations aborted

what can i do????
[Shield Tablet Android Development] D-m-x:
[MENTION=6411851]BitOBSessiOn[/MENTION]: So with the new Shield Update, can we still use the Kernel or should we wait for an Update? Android 7.0 is same but regarding Patches or something like that.

Edit: Seems to Boot fine with 002, couldn't test much if there are any Problems but I assume not.
[Shield Tablet Android Development] gokhujee:
It works fine on shield update 5.2 also got f2fs as well all perfect
[Shield Tablet Android Development] D-m-x:
Yeah, seems to be the case. Just wondering if they added new stuff to the stock kernel since it improved charging behavior with certain chargers and such.

[Shield Tablet Android Development] Norbzzz:
Did you revert back to stock then reflashed the kernel ?

I flashed the OTA, went to recovery (TWRP was still there...) wiped recovery, data, dalvik, and im stuck in a bootloop..
[Shield Tablet Android Development] D-m-x:
I flashed the OTA with Twrp like you did, booted fine but I had other little errors with Apps etc. so much I decided to wipe and flashed back to stock 5.1, let the OTA run and installed custom kernel, Magisk and Twrp again.

Gesendet von meinem SHIELD Tablet K1 mit Tapatalk
[Shield Tablet Android Development] Norbzzz:
Yeah I figured it out late after I had a bootloop with my nandroid backup too. I just forgot I was using F2FS for data as well, as a test.

So now I have the update installed, but I can't get back to TWRP. Tried to reflash it.

When I enter recovery, I get a "no command" error.

Any suggestions ?

Thanks !
[Shield Tablet Android Development] D-m-x:
The no command with a little Android is the stock recovery. Whatever you did, TWRP is not flashed.

Gesendet von meinem SHIELD Tablet K1 mit Tapatalk
[Shield Tablet Android Development] Norbzzz:
Well, flashed it, rebooted, then tried to go to recovery, and it happened.

Reflashed, went straight to recovery without reboot, and now I have no issues at all :)

---------- Post added at 12:37 PM ---------- Previous post was at 12:33 PM ----------

Just tried it with 003, I had to flash the "disabled" version, but the page doesn't really explains the difference between the two, but I can only assume that the functionnaly are disabled, wich seems to be confirmed by the fact that my entropy pool is always low...

Did you had any trouble installing it ?
[Shield Tablet Android Development] filjusz:
I've flashed OTA with T.W.R.P and no issues so far

After 5.2 update i have to install SuperSU and recovery again, I've done that and no problems here :)
[Shield Tablet Android Development] Exile1975:
I think twrp doesn't flash the blob file. You might have to do it from a PC. The new 5.2 update contains a new blob.
[Shield Tablet Android Development] Friedensfurz:
I always used [MENTION=1416222]Steel01[/MENTION] 's blob zip files - you can just install them via TWRP ;)
[Shield Tablet Android Development] ishemes:
Is it just me or is your tablet also a lot more responsive since the last ota? Feels like I already have the BitO kernel installed.
[Shield Tablet Android Development] drewski_1:
Yes, feels snappier for sure.

Just need some 7.1.* love ;)
[Shield Tablet Android Development] primaleph:
My charging with my Samsung charger seems slower though.
[Shield Tablet Android Development] drewski_1:
what kernel version?

---------- Post added at 02:13 PM ---------- Previous post was at 01:50 PM ----------

how can you tell if the Blob was flashed?

i just manually flashed the Blob in Fastboot and at least the Bootloader version did not change from the OTA: 4.00.2016.04-862413b7

not sure what it was from 5.1 or what else is in the blob and easily checkable for versioning.
[Shield Tablet Android Development] D-m-x:
Definitely agree on that, charging got slow to the point where it now takes about 6 or 7 hours to fully charge. I'm not sure if it's 5.2 or the combination with custom kernel.

Gesendet von meinem SHIELD Tablet K1 mit Tapatalk
[Shield Tablet Android Development] primaleph:
I'm using kx10-003b, but k10-002 was no better that i could see.

Charging was slow with stock kernel also.

I wonder if "improved compatibility with third party chargers" for this version means "that unadvertised quick charging is disabled now".
[Shield Tablet Android Development] yreham:
Link please gracias
[Shield Tablet Android Development] filjusz:
No problem with charging here. Aukey charger charge tablet from 0% to full in about two hours
[Shield Tablet Android Development] D-m-x:
Ok, so it's not Kernel related if you tried it with Stock Kernel, I didn't do that yet.

I wondered the same, something did definately change.
[Shield Tablet Android Development] primaleph:
Charging is still faster with the Samsung charger than the Nvidia one. Just not as fast as before.

I'm going to try flashing the dtb and report back.
[Shield Tablet Android Development] Rhadamanthis:

[Shield Tablet Android Development] D-m-x:
Something new on this. I had another Charger in the Drawer (some Asus Charger, dont know where i got it) with the same Output and with this one the Tablet is charged in about 2 Hours. So somehow either some Chargers are not really supported anymore or you could try to switch the USB Cable, some are really rubbish imho and do make a difference.
[Shield Tablet Android Development] primaleph:
The DTB seems to have helped with charging from my Samsung charger.

Has anyone else had trouble with SMB file copying on 5.2? My data transfer speed has been horrible (sometimes less than 200 kb / sec) where before I was getting 5-8 MB / sec routinely.
[Shield Tablet Android Development] xanthrax:
guys , let`s do something different

Let`s post this issues accompanied by this additional info

- flashing style ( dirty or clean )

- Ampere stats

- kernel stock or custom ( tweaks applied over )

I`m too using this device and I`m really interested to make it work better

I'm new here on XDA and a little bit about my device

Wifi shield tablet k1 Wifi Lollipop 5.1.1 whit stock Kernel kexec hardboot patch 3.1 Moddied twrp mrom 2.8.7 Unofficial MultiRom v33

And what i want to know is i assume i use the Bit0 k10 in folder 001 correct i just wanted some clarification yes or a no
[Shield Tablet Android Development] boswelja:
I'm not sure if k10 supports Android lollipop. Have you considered upgrading to nougat?
[Shield Tablet Android Development] Vespirah:
Yea i thought about it i have mixed feelings about upgrading i kinda like where i am as far as OS but if i can find a good performance kernel that also supports multirom and also LP i will do so it is kinda hard finding stuff that is compatible whit shield tablet k1 on LP anymore and thank goodness for xposed framework which allows me to get more out if and i am aware it supports MM but no signs of it coming to Nougat anytime soon i know Rovo is probably working on it

Edit: over the past several months tho i have noticed a strange behavior how it charges so i did fastboot flash dtb tegra124-tn8-p1761-1270-a04-e-battery.dtb just a little while ago thinking that would fix it but instead it bootloops any idea how to fix it

Edit: nevermind lol i forgot flashing just the staging blob does the trick man its been awhile for me tinkering around whit files lmao
[Shield Tablet Android Development] Baldyshugga:
Still no info on Cifs support?
[Shield Tablet Android Development] Norbzzz:
Last update (5.2) with this kernel and Crossbreeder really makes this tablet shine again.

Only major issue I had is the charging time : it now reports incorrect estimation, and takes about 8 hours from 10 to 100 %.

I don't know if it helps, but when OS reports 89% battery, TWRP shows 100%

I don't care about charging really quickly, but the charge is slower than the drain when watching netflix, so that's a bummer.

I used to charge in about 3hours and a half.

Not sure if that's due to 5.2 updates or kernel, did a fresh install but didn't test the tablet without the kernel.

Didn't tried DTB, but as the last time is was worse for me, I want to take some time to do a nandroid first.
[Shield Tablet Android Development] filjusz:
Latest update make my tablet charging quicker, from 2 hrs and 20 mins to just two hrs
[Shield Tablet Android Development] D-m-x:
For me it was the Charger. I switched it with one from my Drawer and now I have the same results, about 2 hours. I think they did something to some 3rd Party Chargers. [MENTION=5368219]Norbzzz[/MENTION]: Did Crossbreader change something for you? Also any side effects? And which Version did you use?
[Shield Tablet Android Development] primaleph:
It was a bad cable for me. My charger seems to be fine too.
[Shield Tablet Android Development] TotallyAnxious:
Could you add the selinux patches that remove the verified boot state? I think safety net detects and doesn't let you install Netflix.
[Shield Tablet Android Development] Zephyr918:
just install magisk and install the netflix apk without store. Might not even need magisk for that.
[Shield Tablet Android Development] TotallyAnxious:
Already did that. There's different levels for the safety net API with app installs. Irregardless of magisk hide. I know I can install apk. But automatic updates are much nicer. Not to mention who knows what apps will start banning unlocked bootloaders. :)
[Shield Tablet Android Development] Zephyr918:
I just installed an older version of netflix. The play store saw it. Updated. Magisk hide working, as my account will still play movies. I dunno, why it wouldn't work for you. But it's worth a shot? Using Magisk 13, updated from 12. Some mods wont alow safetynet to pass. Like xposed. Then magisk hide wont work at all.
[Shield Tablet Android Development] D-m-x:
It works, doing that myself. What most forget is to wipe the play store cache to re certify the Devices if it was once booted up without Magisk Hide.
