[DEV] Lenovo Ideapad A1 Kernel Development/Testing

Warning/disclaimer: This thread is intended for those who already know how to compile a kernel and have a working knowledge of Linux and its derivatives. There shouldn't be a great deal of risk involved, but you are responsible for what happens if you decide to follow these instructions.
Polite request: Please don't post replies to this thread that aren't of a technical nature directly related to compiling, modifying, or testing the kernel.
Introduction:
It appears as if Lenovo have released a buildable and bootable kernel source. I've done some preliminary testing with it. However, it would be better if we could get lots of people building and running the kernel, so that we can spot any remaining problems. This is also an opportunity to start hacking it to add/fix features such as USB OTG, etc.
Kernel source:
Get it from the Github repository at: https://github.com/gmarkall/lenovo_a1_07_kernel
Toolchain:
The Makefile seems to suggest that Codesourcery 2010q1 has been used by Lenovo to compile the kernel. Get it from https://sourcery.mentor.com/sgpp/lite/arm/portal/release1293, and make sure that the arm-none-linux-gnueabi-* binaries are on your path.
Building the source:
You may wish to edit the Makefile around line 192 to set CROSS_COMPILE=arm-none-linux-gnueabi- instead of the hardcoded path that is the default.
Then, to build the kernel:
Code:
make distclean
make a1_07_defconfig
make uImage
Booting the kernel
Normally, Android devices have two boot images that consist of a kernel and a ramdisk. One boot image is for the recovery, and the other is for the Android system. This makes it safe to flash a new boot image containing an untested kernel for the Android system, since the recovery can always boot up using the other boot image. However, the A1, by some bad design decision, only has one kernel - the bootloader always loads the same kernel, and just loads a different ramdisk depending whether it is to boot into recovery or system. As a result, it is not safe to flash a kernel to your A1 unless it's already been tested, since a bad kernel will make it impossible to boot from the internal memory, and you'll need a bootable SD card.
The solution to this problem is to make a bootable SD card for loading the kernel and ramdisk from. A bootable SD card consists of two partitions:
* A small bootable VFAT partition, that holds the X-Loader (MLO), U-Boot (u-boot.bin) and the kernel (uImage).
* An ext2 partition that holds the root filesystem.
In order to create a bootable SD card, use the omap3-mkcard.sh script that is attached below. To invoke it for making /dev/mmcblk0 a bootable SD card:
Code:
sudo omap3-mkcard.sh /dev/mmcblk0
You may need to hack the script if your SD card device isn't a /dev/mmcblk* one, since the script searches for partitions denoted "p1" and "p2" - this may need changing to just "1" and "2" respectively (thanks Xbdesign and Brancaleone for this).
This will create the necessary partitions, set the bootable flag, and format them. You will then need to mount the first partition (e.g. /dev/mmcblk0p1), and copy MLO and u-boot.bin to it (also linked below). Then, copy the uImage that you built from your kernel tree, which will be located in /arch/arm/boot. You can now unmount this partition.
Next, mount the second partition (e.g. /dev/mmcblk0p2). This will need to contain the same set of files that the initial ramdisk contains. There are two different ramdisks that you might want to use - one is from the Cyanogenmod 7 build, and the other one is from the stock system. Download links for these are also below. To extract the ramdisk, copy it onto the SD card second partition, then run the following commands (assuming the ramdisk is called ramdisk.ub):
Code:
dd if=ramdisk.ub of=ramdisk.img.gz bs=64 skip=1 # Strip off the U-Boot header
gunzip ramdisk.img.gz # Unzip
sudo cpio -idmv < ramdisk.img # Extract the cpio archive
Then, unmount the second partition of the SD card.
You should now be able to remove the SD card and insert it into your A1. Power down the A1 and power up again, and it should hopefully boot from the SD card and load your kernel. If it's booted from the SD card and loaded your kernel, you should be able to see that it was compiled on your host by looking in Settings -> About Phone -> Kernel Version.
Troubleshooting:
This is not a comprehensive guide, just a few pointers to where a problem might be - please post replies to the thread to get troubleshooting suggestions.
System boots up, but is not running my kernel - it didn't boot from the SD card. If the A1 is plugged into the charger/USB, you sometimes need to reboot multiple times before it boots off the SD card (I think it doesn't always turn off fully when the charger is plugged in).
The static Lenovo logo flashes up over and over again - it's booted from the SD card, but didn't manage to load your kernel
The static Lenovo logo comes up and stays there/goes to a black screen - it's probably loaded your kernel and mounted the root file system, but failed to mount /system. Try running adb shell to see what happens. If you get something like
Code:
/system/bin/sh: no such file or directory
then your kernel is running but /system isn't mounted.

Ramdisk for Cyanogenmod 7
Ramdisk for ROW 2643 stock release
I've added the two ramdisks that I suspect will be most common - if you need another ramdisk, you'll have to extract it from an OTA.

Also, I compiled a tun.ko - www.doc.ic.ac.uk/~grm08/ideapad/tun.ko
Here's a cifs.ko - http://www.doc.ic.ac.uk/~grm08/ideapad/cifs.ko
EDIT: AutobahnA1 and infraredevans have confirmed that tun.ko works on ROW_2643.
EDIT 2/3: Please test out cifs.ko! (It doesn't work - it needs slow-work.ko. Will get that done when I can. Thanks to Ilikecokethree on the Lenovo forums for pointing that one out).

你懂中文吗，大神！
我是中国人 关注你的帖子很久了，我不懂英文，用翻译软件看的大概，我们这里很多人支持你，都在用你的rom 很棒！比联想官方的好多了，谢谢！

I think I did exactly the steps as you told, but it still boots the original kernel, may something be wrong? Thank you very much.
PS: I'm a chinese too, and my English is not good either

Please do not forget to try the WiFi-based geolocation, which is also missing!
I wish I had the knowledge to work on it myself but I am far from taking over such tasks...do not have the slightest idea about how these things work.
Good luck and please keep us informed!

Geolocation bug has nothing to do with kenerl. It's a missing entry in framework-res.apk in ROM from Lenovo

Sounds like it's booting from eMMC instead.
Can you post the partition table of the SD card as listed by fdisk, and also a directory listing of each of the two partitions? I ask this to confirm what's happened - seems like you're the first person to follow these instructions, and it's quite possible I made a mistake somewhere.

Apologies for the off-topic, but I think that we are discussing two different things here: I am referring to the Geolocation bug, which prevents me from e.g. checking in with Foursquare by using only WiFi location information (active GPS signal is needed) while you have solved the Geocoding bug, which has nothing to do with the Geolocation one...
Please correct me if I am wrong.
@Graham: I plan to install the CM7 that you have been working on (with the feedback from other users - I keep an eye on that thread!) but since I use my A1 for professional purposes as well, I would like to make sure that everything is working fine before moving to CM7. Apologies for not being able to contribute to the beta testing of CM7 but I am really looking forward to seeing a version based on the source code provided by Lenovo, which I think will lead to a more stable version of your CM7. I cannot thank you enough for taking the time to work on this, really!

I think that whether it works in CM7 or not, it almost certainly isn't a kernel issue. I'll test it by signing up for Foursquare and give it a try out on CM7 to see if it works later on. Will post my findings in the CM7 thread.

Hi Graham,
just gonna pile up several questions/thinkings and feel free to comment them the or answer on your liking
We do have few hickups on CM7 but I am more excited about idea of having proper recovery then ironing current CM rom that works more than satisfactory right now. Do we have enough code (I assume that target here is u-boot) on our hands that someone can implement necessary changes to internal partitions and boot procedures?
what is your opinion on replacement of u-boot with something else? for example LK loader or to be more precise with its current HD2 implementation known as cLK. it allready has some neat features like HBOOT like GUI, ability to change partition sizes on device itself (without computer), ability to boot from different partitions (would be nice to have android and ubuntu side by side loaded on our devices) and last but not least it has fastboot support enabled...or is it better way fill up u-boot with desired features if possible?
so...just my wishful thinking...not enough knowledge on my side to do anything regarding all this just hoping that some of you, more capable guys gets interested in this

I do want to implement something that's pretty much as you describe. My biggest motivation is that it's currently not safe to flash a kernel since you can break both system and recovery that way in one go - I really want to make the boot process more robust.

The tun.ko module works perfectly with openvpn on 2643_ROW.
I can now access my Amahi home server,awsome.
Thanks a lot you are doing a great job.

Here it is: http://www.doc.ic.ac.uk/~grm08/ideapad/cifs.ko
To compile it I had to copy md5.h from another kernel source to fs/cifs in the kernel tree. I also had to edit init/Kconfig so that CONFIG_SLOW_WORK defaulted to yes. I configured the module with the options:
Support Legacy LANMAN servers which use weaker security
CIFS Extended attributes
CIFS POSIX attributes
and without statistics, debugging, or experimental features. Let me know if this is a suitable config - I could always tweak it and build another one.

I did - I didn't have any problems, but my random guess about how to solve it could be to install ia32-libs. If installing that doesn't solve it, can you post a bit more detail about the problem?

I am using ubuntu 10.04 LTS and just cant install / find Getlibs to install a 32-bit version of xulrunner :-(

Do you need that to run the installer? I just downloaded the tar version instead and extracted it. I saw there was an installer as well, but I thought it would be more hassle than using the tarball so I just ignored it.

Tubuntu - questions and issues

This should probably be posted here, but I sadly don't have the required 10 posts to do so.
There's one issue that I noticed that is actual in 0.2.2alpha. When you choose to flash Jhinta 3.1x kernel and not 2.6x kernel, it is still linux.img that is being flashed, instead of jlinux.img.
Also there's one question (or rather a feature request). Once you have dual boot up and running it would be nice to be able to flash linux rootfs only (ubuntu.img) without changing the partition table and loosing current android install. You can't currently do that with Tubuntu, right?
Best regards,
Alex

new version is up with Flash rootfs only :laugh:
future release of kernel i will put cifs. right now i'm trying to get zram and overclocking right 1st.
lol i feel like a one man operation. make the program to flash ubuntu images, didn't find one i liked. so i went ahead and made one. feel that the kernel is missing too much stuff. and went ahead and i'm making that now lol... am i missing anything else i need to learn/do? hahahaha
but i'm loving it!
thanks for the support

Thank you for your effort
Speaking about your own kernel, I tried compiling one from Jhinta source, but I received odd errors at boot time. First it was this kind of errors:
lists.litmus-rt.org/pipermail/litmus-dev/2012/000215.html
it was suggested there to try changing CONFIG_DEVTMPFS_MOUNT kernel config value, I did that, and then I got some other odd errors, so I gave up
Right now I have a more or less stable 12.04 kubuntu+3.10.1 jhanti kernel with hw acceleration, sound, zram (used netinstall 0.6). I'm only missing overclocking and a cifs module, that's why I tried building my own kernel, but never got it booting. I don't know any sane methods of backing up and restoring linux on tf101 (well, dd + gzip should work, but that's rather stupid), so I'm a little hesitant about flashing your lubuntu right now. I think I'll still give it a go, but before I do that, don't you know any easy way to back up my current linux install?
Thank you

i'm now compiling from his source. for the 3.1.10 kernel i'm using. why try to reinvent the wheel? i just recompiled and added oc and cifs, i didn't run into any compile issues but i did run into boot issues so changing the kernel to compress with lzmo instead of gzip fixed it. hope that helps

x3maniac I was wondering if you have ever checked out openELEC linux. They just pushed out a new version on Distrowatch and it looks like it will have support for ARM devices. It is very lightweight at 106mb and is made to run XBMC out of the box. Might be worth a try due to its size and media streaming abilities.
Thanks

On another note if I do end up getting around to trying your method with arch which desktop would you recommend?

Compression was already set to lzma. I can't figure out what I was doing wrong. Yet, you're right, no point to reinvent the wheel.
I see you've recently released your Lubuntu V1.1-rc1. The specs sound great! Could you please post the rootfs download link and also post your kernel img?
Thank you for the great work you're doing!

I gave it a go First of all, Tubuntu flashes .\images\linux.img when choosing to flash "2.6x x3maniac kernel", I assume it should flash .\images\xlinux.img
That's not a big issue, but should be fixed
A quick list of things I noticed.
1. Things that work:
-1.2 GHz OC
-Usb mouse (when plugged before system boots, otherwise not - that's due to 3.1.10 kernel, I guess)
-cifs module
-chromium
-terminal (right clicking on your tf101linux gadget -> Shortcuts -> Terminal)
-screen brightness up/down buttons. You just have to be mindful to avoid turning the screen off this way - it won't turn on afterwards and you'll have to force reboot.
-ntfs read/write
2. Things that don't work:
-touchpad
-XF86poweroff button
-System Tools -> XTerm/UXTerm
-sound: Audacious complains "ALSA error. No suitable mixer element found. snd_mixer_find_selem failed". Gnome MPlayer just won't produce any sound, and youtube html5 videos too.
-plugging in an external usb drive. It's totally ignored. A pen drive doesn't even blink, nor the drive appears in /dev it works now. It didn't during initial launch. Don't know why, but a reboot cured this.
Also, it happens quite often that system freezes for no apparent reason and only force reboot helps. It happened twice with me already, although it's been less then an hour since I flashed lubuntu.
Tell me if you need some additional info

i love your report! keep up the good work. this helps me narrow down the problems but without a dock i can't fix some of the issues. but try this
touchpad:
edit /etc/X11/Xorg.conf
Code:
Section "InputClass"
MatchIsTouchpad "on"
Identifier "Touchpads"
Driver "mtrack"
EndSection
should fix the touchpad issue.
i will look into fixing my script for the brightness issue. located int /usr/local/bin/tfbright
what were you doing when you freeze? i don't have a dock(still waiting for it in the mail) so i don't know if it's related to that.
i've been looking at nvidia git and downloaded there source for the linux4tegra kernel. it' compiled fine but wont boot. don't know why yet

x3maniac, I know it is off topic a bit but I just wanted to mention that I appreciate your attitude towards your work and especially criticism (aka feedback) from others about your work. Reminds me of my EVO 4G days running tommytomato's classic rom. His threads were always friendly and optimistic, much like your own.

Strange, but there's no /etc/X11/xorg.conf
I tried creating it with `Xorg :1 -configure`, but I get "No devices to configure. Configuration failed."
I also tried creating /etc/X11/xorg.conf with the following content
Code:
Section "InputClass"
MatchIsTouchpad "on"
Identifier "Touchpads"
Driver "mtrack"
EndSection
but touchpad wont' work.
Like I said, there appears to be no apparent reason for those freezes The only things they had in common are the following:
(as far as I can remember)
-I had a cifs share mounted
-pen drive was plugged in
-chromium was opened
I understand that isn't helpful at all, but atm I can't reproduce those freezes myself. They occur kind of randomly.
I hope linux4tegra kernel does boot after all
Thank you for your work
EDIT: 30 minutes without freezes, I hope they're gone for good! :laugh:

x3maniac, I know it is off topic a bit but I just wanted to mention that I appreciate your attitude towards your work and especially criticism (aka feedback) from others about your work. Reminds me of my EVO 4G days running tommytomato's classic rom. His threads were always friendly and optimistic, much like your own.

as far as i see it, you guys are helping me get a working version. user/tester are as important as the devs making them. or else dev's would be out of the job. lols that's how i see it

I let lubuntu running and it froze smth like 20 minutes ago Without me doing anything. Chromium was running, pen drive plugged in and a cifs share mounted.
I'll leave it running without a pen drive plugged in, shares mounted and chromium running to see if it freezes eventually.

i'm guessing jhanti's kernel is not stable. i was starting to use it more and got a random freeze. cpu1 went to sleep and wont wake up. looking into that.. i might just take nvidia's kernel 3.1.10 and try to get that working.

[ROM][Development] NEC Terrain custom ROM

Hello!
This is a development thread for those who is ready to contribute to the creation of a custom ROM for NEC Terrain.
The prior steps, which are bootloader unlock, rooting and even repartitioning have found their solutions and can be found in:
http://forum.xda-developers.com/showthread.php?t=2515602 for the discussion
https://github.com/x29a/nec_terrain_root for an apk which opens for you an ability to have the system area of the phone writeable
https://github.com/alex-kas/nec_terrain for the last ideas on how recovery and boot images should look like and the repartitioning
So, all questions regarding all the above should be asked in that thread as they are off-topic here.
For more general questions regarding the present rom, programs to disable, features and current bugs/oddities, please, see
http://forum.xda-developers.com/general/help/q-nec-terrain-discussion-t3162070
Thanks for understanding the thread aim and welcome to development!

Found this CWM recovery creator online. Apparently you can just upload the recovery img that comes with a phone and it will generate/build a recovery based on that. Worth a try?
EDIT: Here's the link. Apparently it is necessary for some phones to upload additional files to get the recovery to work properly. I'll look into it when I start to build this thing

alright......so ADW launcher is very very unstable with this ROM. Basically spontaneous reboot every 30min or so.
I need 5 panels, and the stock launcher can add them, but it always make the second panel default, which is very annoying.
So which launcher do you guys prefer?

Have I found?
Unfortunately this builder does not spit output ...
I got a strong impression the Terrain is reduced CasioCommando with qwerty. @MrMEEE, I suggest to investigate this direction. The later phone is reported to have both: custom roms and custom kernel. xda has developments on this.
This guess is NOT because NEC is Casio, this is because I found that both phones use for some unknown device the so called ktrc_driver.ko kernel module and the only device apart from Terrain which I could spot by google is CasioCommando. Then, of course, accounting that NEC is Casio I make this conclusion.
Also the boot of Terrain contains commands and even kernel modules references that do not exist. I have a gut feeling that devs were in rush and just were porting some system from another phone.
EDIT: I found a binary custom recovery for commando and so far it is the ONLY recovery which comes to some graphical image! I learned that graphics is device-dependent and presence of some colored points suggests that the graphics driver is correct. One just need to adjust the resolution ... This supports my theory that commando may be the prototype for the kernel.
Will try also to look into all of that.

Probably explains why we have an HDMI selector in the build.prop, huh...
But wow, that's an astounding discovery! Never would have guessed NEC = Casio. I believe there are 2 Casio Commandos, I assume you are referencing the newer one?

If you are correct, then the kernel source is available here:
http://www.casiogzone.com/us/download/index.html
I'll look into it..

GPL or not GPL?
Citation from http://wiki.cyanogenmod.org/w/Doc:_porting_intro:
"The manufacturer or vender of any device using Android will minimally need to make the source code available for all GPL components upon request, including (and especially) the kernel. You definitely want to request a copy of the kernel source and keep it handy."
Can anyone clarify the tedious question in the subject? I mean, does running android implies gpl on kernel? Can anyone (NEC, ATT, Qualcom) hide the source and what the conditions should be then? Can they have proprietary blobs in the kernel?
Weird

Android runs on a standard Linux kernel which is GPL covered. Android is really just a Java VM inside of a Linux kernel I believe. So yes, Android kernel IS Linux kernel so therefore it would be GPL covered (thanks for the explanation @Nardholio )
They understand GPL. Anything based on the Linux Kernel must have the source released, so AFAIK there is no "proprietary" in a Linux Kernel... however that is just my understanding and if I am wrong someone please correct me. If they put "proprietary" code in the kernel and try to use that as an excuse to not release it, I say "Too bad, that's not an excuse, since you understood GPL when you built the kernel but are refusing to follow it. Guess what, now you have to release the kernel AND your "proprietary" software! LOL!!!"

I posted this in the wrong thread. Long story short I found someone interested in helping enforce the GPL for the Terrain but I don't own one. I need someone who owns a Terrain (preferably directly bought from AT&T or NEC) and who has already requested kernel source and either received no response or a refusal (I used the feedback form on NEC's website and got a polite refusal a few days later but I don't own one)

Sweet. PM me your email address and I will hand off my communication with the SF Conservancy to you. Just saying you can go to kernel.org and download the Linux kernel is NOT a sufficient response. They need to provide full source to boot the device (including board files, device drivers, any in kernel firmware, and build scripts)

YOU WILL NOT BELIEVE!

I pressed NEC to deliver it. Have no time to check right away the integrity. Also, I have some problem downloading from CAF (I'm in a place where git is blocked). Maybe will ask someone to help (re-download to an http store).

Well sh*t... Never thought this would happen in a bazillion years.
Yet if you read their terms and conditions, it states you aren't allowed to reversed engineer their software to a "human readable form". Is this nullified by GPL, or can we be in trouble for using their kernel source for a ROM?
EDIT: Just downloaded myself a copy of the kernel.

First experiments
Results for the moment are like this:
1. The kernel does compile with the modified files with no compilation issues at all.
2. The kernel is smaller then the stock one.
3. The recovery.img produced by full caf build does boot but halts at the android image with the red triangle. Or perhaps does not halt but I did not come with a key combination to proceed.
PROS: graphics works
4. The kernel being stuffed into original boot image does boot, shows boot animation WITHOUT boot sound and then not surprisingly goes to a bootloop flashing the home screen
CONS: seems that sound is not here yet
5. The bootloop was broken using
adb reboot recovery
which means that adb does function
6. I did not try to flash the whole image to check whether bootloops are due to somewhat above the kernel (aka this kernel doesn't work with the stock soft).
Overall, we have a messy kernel source which however at least boots to init, communicates with adb and has graphics.
I'm free for a team project: who is in?
Technically, to make this particular caf manifest I had to install a virtual ubuntu 10.04 x64. My native machine failed to compile. I have gcc 4.9. Even the downgrade to 4.4.7 did not do the job. And for some reason I failed to compile gcc 4.4.3 for my machine. ubuntu 10.04 has gcc 4.4.3. But there you need to install some stuff and update the present there python (it is just 6.5 there but still some update exists still inside 6.5 and it fixes somewhat causing a peculiar error during the build). Also, be aware: you cannot compile on a virtualbox share: mmap does not work for security reasons. You must arrange ALL inside the virtual machine. After the build it is about 53GiB. So, the vm-drive should be at least 60 giga.

Progress Inquiry
Happy New Year!
Just wondering if any progress has been made for this particular device. I understand we all have lives and things get in the way, or interests wither away, its just an inquiry. I'd love to see an update to this device, even up to kitkat if that was possible. Any suggestions on how to recruit developers whom may be interested in the challenge of custom rom development for this device?

Im also wondering the same thing

Yes, have been able to flash my own system and it is also possible to get ADB.
I am currently working on it, but it might take some days to get something useful out of it. As I just created a new account here, I am currently not able to post any links, but you can find my stuff linked on Twitter via @nexus511.

Short update:
I have been able to gain root and I have also been able to modify selinux policies on the device. Then I have been running into some strange behavior. It actually looks like the kernel is telling to be running in permissive mode but even a permissive context seems to be enforcing instead.
I will try to use something like "Magisk" instead and see, if a service can solve this issue.
For anyone interested: The kernel-config can be extracted via /proc/config.gz. The dtb is compiled into the kernel image. Maybe I try extracting the dtb and building a codeaurora kernel for the device and see, how far I get with that. This might resolve the strange selinux issues I currently see.

@nexus511, any way you could please share the root procedure or point to some resources?
Or...at the very least when you get a spare second, how you did manage to unlock your bootloader knowing Nokia has publicly acknowledge disabling Device > Developer?

Could you remove the pre-installed apps?

Hi!
It's possible, to get full ADB-Root by injecting a patched adbd-binary. And with real swap instead of zram, the device is more responsive (background-tasks like Launcher/Homescreen are killed less often...)
As soon, as I have build my own patched adbd, I will provide an 'update.zip' -- it seems chainfire doens't like others to use his version. (OpenSource -- anyone? )
BTW: no, I don't have 'su' -- only my own priviledged additional startscript and ADB-Root but for me this is more than enough to 'work'
(my goal is to create native apps with Ada/Gnoga - meaning native but with HTML5-GUI. First tests are working well...)

I would love to have this phone without the pre-installed social media and game garbage, would your planned update.zip allow someone reasonably competent at following instructions to do this easily or is experience required?

It should be possible to remove those apps - but for me it's hard to say how. On my device there were no preinstalled apps/games other than snake. Everything else is (un)installable normally. Could be a region-thing
(I've got the european/german version)
-- but on my device the store seems to be a 'static' bunch of zips - so it could kill the store to just remove those.
(i think I would need to adjust configs for the store if I want to clean them up)
If I remember correctly, there is a flag in the app-manifest to config if an app is removeable... my first try would be to edit this flag and check if I could uninstall it normally after this
On the other hand: there is nearly no need to uninstall - KaiOS-Apps are small and with a sdcard....
(I created an extra 1GB-Swap on /data - even then enough space left)
BTW: if You have a little experience with android-stuff, rooting is simple when You know how
Enable adb --> just type *#*#33284#*#* on keypad of your phone (the digits spell 'debug' )
-- build an update.zip - sign with AOSP-Test-Keys
--- let it create '/data/opt', '/data/opt/bin'
--- put an patched adbd (chainfire's v22 works) in /data/opt/bin
--- create /data/opt/init as a shellscript, remounting / rw, replace /sbin/adbd with patched one, remount / ro kill adbd so it restarts the patched version. (you may add commands for other stuff on boot - I disable zram, enable swapfile, start en Ada-Server....)
--- and add a call to '/data/opt/init' as last line to '/etc/init.qcom.post_boot.sh' so this 'init' will start with root-rights on startup.
This way /data/opt/init will inherit root from /etc/init.qcom.post_boot.sh, so it can replace adbd - and because the patched version won't drop it's root-rights you'll have a root shell over adb.
As You see - it's quite trivial, but at the moment I don't have a patched adbd which I'm allowed to include.
(I hadn't time to build an AOSP-tree until now)

Has anyone tried installing OmniJB from 4pda.ru website? (Sorry can't post links)
If you google "4pda 890710" it will bring it up.
Also, anyway of installing whatsapp yet?

root or create an update to edit /data/local/webapps/webapps.json
it worked on my phone no more s*** games and google stuff

Can I not just replace the /sbin/adbd from the boot.img?

OC-K1 Nougat

3.0
given up using peoples dirty code, so downloaded nvidias dirty code instead lol
cleaned the code up best i could, things ive noticed while playing games on the tablet is -
when i play "nitro nation" the first race no longer stutters
when popups appear they dont take a while to appear..
when i play "word mind" it doesnt take ages to load with crackling sound
when using "kernel auditor" if you set the GPU max and min values high (i only did this trying to keep the values standard), when the GPU gets hot, it cant scale down the GPU frequency so it starts trying to kill tasks.
i dont think you need to download/flash blobs as they are for flashing binary stuff, but i cant find a need for it, think its more of a precaution to ensure the kernel boots.. but dont think i have flashed them
-----------------------------------------------------------------------------------------
3.1 : FINAL,
dunno what changes i made but ive recently upgraded my tablet so figured id upload my latest and last
obveously i have had to start again running 3.10.96 but done alot of work to make it as fast as i can so far, but i deleted all references to my old code and cant find them anymore,
GPU is now at 914 MAX as ive found its the GPU that generates a lot of heat, which causes it to throttle, and found values higher than this just degraded performance.
ive known for a long time that "DT2W" works great while connected to USB, due to the custom USB wakelock, i know the app "wakelock revamp - power manager" would resolve it. but ive found tapping where "notifications" would be wakes the screen (ive found bottom right where the camera would be is a good spot) im trying to figure out how to apply the wake lock better.
scores on PCMARK are above the scale on most values
scores on 3DMARK are around 3250 ~ 3320

i would still be using a virtual machine which due to it being so slow, i would of probably given up a long time ago

thanks to everyone that has said thank you

Nice to see that you open a thread.
Appreciate a bit companionship here.
In your guide didn't you specify how you create thr zip file.
I used the nethunter installer, which is based on lazy flashed in regard of the external modules, this come in handy, but I found relatively little among the Shield kernel support.
I noticed that you set the make command with the addition of the specifications of the number of CPUs, which are to be used, before every command.
Is this a typo, or is this the correct procedure when you compile with Windows?
Did you mean with
"bin-bash-command"

That's just how I make the command, as if you tap the up key, you can scroll through previous inputs, if it makes it faster- that's a bonus.. but you're right about being very little support.
With regards to the zip file - you could use mine or any other zip that is a kernel flash - as long as you drop it into the kernel folder.. I believe there is an "anykernel.zip" somewhere if you prefer to use that.. also if you wish to add your own personal touch, you can modify the script file in the metadata folder

I also chose different colours in the guide and placed it in a separate line so people could understand the exact typing.. or they could copy and paste..
But with regards to support it is one of the reasons I made the guide, in hopes the Nvidia community could follow it, understand how to achieve their own kernel, and improve the tablet. As there seems to be a serious lack of support..
I had to learn on my own, through Google and YouTube, but hopefully this will speed up what took me a month of trial and error..

Is it compatible with stock based fw (5.4)? Just need to flash blobs, then kernel and reboot?

Respond
Yeah, extract the blobs before flashing.. only available for stock/stock+ rom

Oh, by the way, you can’t compile with windows unless you’re using a virtual machine.. has to be Linux/terminal

Thank you, I will try out as soon as I can get to my computer. I have downloaded the wakelock v3 app and kernel adiutor an I can't enable wakelock in kernel adiutor (I can't see any option for it). Only this new kernel will support this option, am I right?

You must of done something wrong as “wake” is below “gpu”
You extract> then flash the blob at the fastboot menu via typing - fastboot flash staging <blobfilename>
Then via TWRP recovery you install the “OC K1” kernel without extracting.. I have 3 tablets and it’s worked on them all.. hope this helps,

Thanks for letting me know, originally you wouldn’t of needed the “wake v3” app, but I started fresh, which gained performance, and I decided to look for an easier way to stop the tablet “deep sleeping” on me.. less of a headache this way :laugh:
