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.

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!

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.

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.
sediROM for LG Optimus F3Q - Custom ROM (codenames: fx3q, d520)
This is about building a custom ROM like Cyanogenmod or AOSP working on the LG Optimus F3Q.
Introduction
First of all: At the moment there is no CM or AOSP based ROM available for the F3Q. Not yet.
That said it means I try to port CM (or build pure AOSP) to the F3Q and this is this thread about.
Some words about me and what I do:
I do Android ROM development since June 2014 mainly doing things based on stock.
Before the F3Q I never had to do with porting CM or AOSP to a brand new (no not such "new" anymore) device before.
New means "no file device tree" etc available. So I dive into porting months ago and still learning every day new things here.
Porting is nothing you can learn in a week or so The main problem with porting is that there is not much you can read or
where you can get many help for. The guides out there are very generic and to be honest the best would be having a pro on your site
which guides you through all the problems which WILL occur when porting.
Before starting I never heard about "loki", doesn't know how TWRP gets compiled or created an Android kernel with or without CM
automatism. In the meantime I compiled a working TWRP version, having a kernel in place which allows to boot unsigned system
images and many more. The only "little" thing left is to get CM ready.. Nevertheless I have 2 things which helped me a lot over
the years: patience and "never-give-up".
The state:
If you ever tried to compile Android or CM by your own you know that you need a valid file device tree (in this case "device/lge/fx3q/")
which contains all the stuff which describes the hardware, the things to do, proprietary files you cannot compile because their sources
are kept by LG and so on. Building that from scratch is a pain in the a.. so you need to find another device whose hardware is as much
the same as yours. In this case this means LG Optimus F6 which has the same processor etc. The great thing is that there are people
out there who had build a working device tree for the F6 which means it should be possible to have the same for the F3Q!
The problem is that before I used the DT from hroark and fixed several build errors there and well now I use the very much more newer
one from dm47021 and this means: adapt everything again, fixing build errors again..
Even when there is such a valid base available from a device with same specs this does not means it would simply work when copying
it over.
I need to adapt nevertheless many things to get the sources at least compiled! and then the question is what works and what not.
This is where we are atm: Fixing compilation errors (fix 1 and you get 2 new) and then we will see..
For updates about the state scroll down to the "current state" topic.

Done:
Lokifying (without that we were absolutely L-O-S-T!!! BIG thx @djrbliss) process is done automatically by my self created build-script (took me some time but was it worth)
Lokifying means: due to a hack by @djrbliss (click here and click at his THANKS button!!) we can trick the locked bootloader to boot whatever we want!
boot a modified compiled kernel with the stock ROM / or hLe stock ROM
custom 3.4.0 kernel with kexec(disabled atm), xattr, selinux support and much more based on the stock kernel sources (sediKERNEL thread)
the ability to boot unsigned ROM's provided by sediKERNEL
Fully (or mostly) working TWRP version where storages correctly mounted and backup/restore working fine (TWRP thread)
adapt hroark's device tree of the LG optimus F6 to the F3Q (superseeded by dm47021)
adapt DM47021 DT to F3Q and compiling CM KK systemimage/full otapackage (do not expect too much it simply means that I was able to fix all the thousands of compilation errors. which is GREAT but now the debuggin starts)
Rebasing EVERYTHING of the file device tree to the f6mft one by Dm47021. Reason: CM is now available for the F6 which is damn great because we use the same hardware in many cases. I currently rewriting everything from scratch, adding the correct proprietary files etc. Will take a while but hopefully then we get more in the right direction then before.

undecided: compiling AOSP JB
undecided: compiling CM JB
Stalled:
compiling CM11 kernel based on the F6 device tree (too many compilation failures)
compiling AOSP Jellybean including the LG sources works (but different issues with booting)
compiling AOSP KitKat including the LG sources fails (doesn't start at all because of several changed vars maybe. Didn't investigate that further cause I focus on kernel now)
compiling CM JellyBean fails with the adapted LG Optimus F6 device tree
MultiRom (discontinued as sediKERNEL can now do all I need):
Multirom TWRP = compiling OK but no screen shown?!
Multirom binary = compiling OK
Multirom trampoline = compiling OK if it works or not? Cannot test it until TWRP
Kexec Kernel = Porting to F3Q (hopefully) finished. compiling OK but it has problems with mounting the correct places (I think. Didnt investigate that further atm)

Questions & Answers
Frequently Asked Questions (FAQ)
(in no special order)
Question #1: Is CM or pure AOSP (or similar) for this device available now?
No. Not AFAIK. If you find some please tell me! But afaik I'm the only one working on that port so if you find someone or you want to help by yourself please send me a PM!!!
I currently trying to port CM to this device and as I'm doing that alone and the whole process is very complex this is nothing you can do in 2 weeks or so.
Question #2: When will be CM or pure AOSP or similar available?
When it is ready. Sorry but for this no timeline can be made. I will update the OP from time to time so come back often to check if there are any news.
Question #3: Why are you doing this?
Well .. the main reason is I want to have an absolutely fully localized (German) Android for my wife. Yes it's that simple. There are plenty of apps who can switch the language in many dialogs but all LG ones (like settings, power menu etc) are all still English.
The following may harm you but the F3Q is not a device I would buy for myself. I do not really like it's design, it has more weight and height than my current one (Samsung i927). Ok not all is that bad: What I really like is the physical keyboard which is much more better than from the i927..
Nevertheless I own a F3Q since a while because the community sponsored one to me which makes it possible for me to continue developing for this phone. Otherwise I had stopped that at the time where my wife used her F3Q productive.
The other reasons are:
There are problems here in Germany regarding the reception: 3G (or better) is not possible (but it should be from the point of technical specs).
Besides that the displayed information about the speed seems to be wrong in some cases but that is another story..
Last but not least the problem of overfilled storage makes me mad (well in fact makes my wife mad but well that makes me mad then). There is always to less even with tricks like moving apps etc.
So in short: I want to be able to fix problems who are annoying me/my wife.
Question #4: I have bought the phone and need to unlock it (service provider lock, network lock, ...) now. How to do that?
Well there are thousands of services out there who offers unlocking and no guarantees wherever you go.
Just 1 thing before you read on:
I'm not responsible if the mentioned site doesn't work for you! For me it had worked but there are no guarantees out there in the evil internet ocean...!
The following describes my personal experiences with those services only. No guarantees no responsibilities no whatever.
I have tested 2 of them:
The first one is a "free" service named www.unlockphone.me.
Free means first of all: WAIT. As an example my request have this as the waiting time:
1027 people are in queue in front of you. 2 weeks, 3days, 10hrs, 14min remaining until you will receive your CODE
The service itself is free but as I do not wanted to wait such long I donated to them 10$ to receive the code more quickly.
Result: Well I got a code but is was not working. I send them 4 mails - never received any answer. Bad luck. That is what I mentioned above. No guarantees. Well you could try it on your own - at least the free one without a donation - and see what happens for you. It's may worth the try.
.
The second one was fine. To be sure: I do not own the following service or get anything for pointing there but I have used them 2 times and at least the service provider lock could be unlocked both times successfully. The first time used they unlocked for $2 CAD (November 2014) and today (April 2015) they unlocked for $7,50 CAD.. Well it still seems to be a reasonable price (at least for me).
freemyblackberry.com
I filled in the following:
Brand = LG
Carrier/Country = USA / T-Mobile
Model = LG Optimus F3Q
When you have received your code (the one way or the other):
if you do not see the unlock screen already type in the following in the dialer: 2945#*520#
in the displayed menu choose the type of unlock you want to do (in my case it was service provider locked so I choosen that)
type in the received unlock code (for my case the freemyblackberry named it SPCK)
the phone may reboot now automatically
enjoy.
Question #5: What can I do to help?
I thought you would never ask! :victory:
The first one EVERYONE can do even when no programming skills is: Use the "Thanks" button. :good:
This is simple, easy and can be done very quickly. This will not speed up anything of course but it keeps me motivating because it shows me that you like what I do.
.
The second one EVERYONE can do is to participate in beta testing versions.
From time to time I release a new Kernel or TWRP version or some day a CM version. If you want to help you should do that by installing those beta versions (if one is available) and telling me about the good and bad of it.
This needs always a full backup and you may need to restore things afterwards but I'm here to assist you as far as I can.
.
The third one is not for everyone: helping to port.
That means going to the steps of CM porting guide and downloading the LGE sources and cloning my git repos. Get in contact with me before so you use an uptodate repo like the device tree etc.
This one would be the biggest effort but it is the most time consuming. At least for the full port.
If you "only" want to help partly like making TWRP better or helping with Kernel development it will be much much easier because those both are already fully working and you can start with fixing things instead of try&error!
That said Option 3 here is the only option if you really want to speed up the process!
.
The last one I can think of is donating, of course. I do not beg for money here - it is simply one of the available options.
One thing about this is important: a donation is much much more motivating then the mentioned "Thanks" click but you also will not speed up anything (Ok you would speed up things when the donation is about 10.000 € or more haha)!
But seriously: I do all that in my free time atm and that means I need to cut out time somewhere else from RL. This is not a problem for me and if you donate or not I will continue until I reached my personal goal.
That simply means that it will take much more time than doing it full time. The only other option would be developing in the normal work hours which means not earning money here for this time. So there needs to be a balance for if I would do that. That said there will be times where I can work on it and may times not for weeks. It depends.
Question #6: What is that "adb" thing?
adb stands for: Android Debug Bridge and can help a lot when it comes to work with your device. It is not for developers only but they use it a lot of course.
But a normal user can use this to exchange files without the need of mounting, backing up the device, reboot the device and use it as a very comfortable way of having a terminal emulator.
.
Normally adb itself is not available as a standalone application - it comes with the Android SDK which is very big and heavy if you want to use adb and/or fastboot (another great tool) only.
But we live in a great world with many people wanting to make things easy so here you go when you want/need only adb and fastboot:
download & install adb @lifehacker
Question #7: How can I find the LG Hidden Service Menu (STOCK)?
Normally you will not need this! But you may want to enable the USB DIAG mode if you're a developer or you simply want to make your phone unusable - so here we go:
As usual: Use on your own risk!
adb shell
su
am start -a android.intent.action.MAIN -n com.lge.hiddenmenu/com.lge.hiddenmenu.HiddenMenu

I know I am getting ahead of myself, but I know some devices have a /datadata partition (like the Samsung Infuse) when ported for a KitKat ROM.
When it comes time to design for KitKat, can this separate partition be eliminated? I know it is done for performance reasons, but with such limited userdata space as it is, another partition would come as a detriment. This has already proved a problem on the Infuse, and they have much more space to deal with (albeit ~600mb /datadata).
The alternative would be building Link2SD into the ROM, knowing that there will still be only a small collections of apps that can be installed.
Unfortunately, because of our limited userdata, we probably won't be able to develop past KitKat, at least end up with something usable. ART will prove to be too much of a pig for this device (storage wise).
Just my nickel's worth...
Bad news..
The Desire Z of my wife is completely broken now.
That means I cannot develop anymore..
- I ported and released the latest TWRP version to the F3Q
- I'm able to build AOSP JellyBean (not booting yet though),
- I compiled and released a custom AOSP Kernel (named sediKERNEL)
.... and a lot more..
I have everything I need to continue here in place...
I have the will and the ability to continue...
But no device anymore..
If someone has a F3Q to give away.. then I will continue but I'm not willing to buy a F3Q for developing only. So if you have an idea how we could continue let me know.
Otherwise that will end here for me unfortunately...
Hopefully not.
Yours
Xdajog.

sediROM for LG Optimus F3Q - Custom ROM (codenames: fx3q, d520)
Recovery:
CWM (I cannot recommend that CWM version atm! Because it was build with not a full valid device tree and is missing features TWRP has included!): https://play.google.com/store/apps/details?id=com.pressy4pie.oudhs.manager
TWRP (highly recommended!): http://forum.xda-developers.com/showthread.php?t=2867339
Done:
Lokifying succesful and is done automatically by my build-script (took me some time but was it worth)
I am able to boot a modified compiled kernel with the stock ROM
Custom JB kernel with kexec support based on the stock sources (stock initrd)
Custom JB kernel with xattr support based on the stock sources (stock initrd)
Custom JB kernel with selinux support based on the stock sources (stock initrd)
Fully (or mostly) working TWRP version where storages correctly mounted and backup/restore working fine (TWRP thread)
Current progress:
Building a custom kernel without stock initrd (Details on the process here: sediKERNEL thread)
To do:
Building a custom kernel without stock initrd
having a working device tree (depends on having an own initrd)
compiling AOSP JB (depends on device tree)
compiling CM JB (depends on device tree)
compiling CM KK (depends on device tree)
Stalled:
compiling CM11 kernel based on the F6 device tree (too many compilation failures)
compiling AOSP Jellybean including the LG sources works (but different issues with booting)
compiling AOSP KitKat including the LG sources fails (doesn't start at all because of several changed vars maybe. Didn't investigate that further cause I focus on kernel now)
compiling CM JellyBean fails with the adapted LG Optimus F6 device tree
compiling CM KitKat fails with the adapted LG Optimus F6 device tree (mainly because some of the adaptions enforces the goldfish emulater?! Havent found out why! damn.)
MultiRom:
Multirom TWRP = compiling OK but no screen shown?!
Multirom binary = compiling OK
Multirom trampoline = compiling OK if it works or not? Cannot test it until TWRP
Kexec Kernel = Porting to F3Q (hopefully) finished. compiling OK but it has problems with mounting the correct places (I think. Didnt investigate that further atm)
Well one of the ideas is to have a working MultiRom installation which then would boot a custom ROM like CM with the kexec technique.
That way we could boot a "insecure" ROM with our locked boot loader.
That really seems to be possible because I can flash a TWRP image to the BOOT partition for example. That means TWRP would start up everytime.
If we could get MultiRom in place where the boot partition sits we COULD be able to boot everything we want.

My current device tree of the fx3q AOSP build can be found here: device_lge_fx3q_aosp

Just so im clear what exactly is incomplete about the cwm that was compiled? you say its not a valid device tree (crazy because ive never heard those kind of terms even used before) what exactly makes it invalid to you?
what was the point of labeling this thread? gain some thanks by saying you spent 200+ hours on compiling the stock kernel source that has a guide to compile it in teh source zip? cuz it doesnt appear to make any progress on booting aosp even though you forked an oudhs device tree from another device. then you talk about needing hacks etc to get past the locked bootloader yet you dont seem to understand that there was an exploit tahts how there even was a cwm.
instead you are pulling in search results giving false hope to people looking for cm in hopes they donate to you so you can buy a phone when you obviously dont understand how it works.

Never said that CWM is incomplete but to be honest it was and it is missing features TWRP has, of course. It is a while ago that I took a look at that CWM version so I would need to check again maybe. The last time I tried it the mounting of /data/media (the internal usb storage) was not possible as backup, too. But that may have changed.

You may have more experience in porting to a complete new device so what is wrong with forking from a device which has more or less the same hardware specs ? That is the recommended way mentioned in the porting guides.
The reason why there was no progress since a while is:
I had no device anymore
Donation offer took some weeks
Then the new (used) device need to be shipped for about 2 weeks
Then I was on vacation for 2 and a half weeks
Then I needed to bring down the workload in RL to continue which took me another week
Then I started with development again since 1 day
Today
The main focus is to develop a fully working initial ram disk build from scratch instead of using the stock one. Then I will continue on porting AOSP as the ram disk is an essential part as you know.
then you talk about needing hacks etc to get past the locked bootloader yet you dont seem to understand that there was an exploit tahts how there even was a cwm.
Click to expand...
Click to collapse
Well it seems that you do not understand but that is not a problem I explain it for you:
The locked bootloader is a problem because normally we have not the possibility to install a custom kernel and/or custom ROMs. There is a hack available named "loki" which makes it possible to circumvent that fact. The only thing you need to do is to use the loki patch on the kernel/boot image.
The other thing around this is that the bootloader send kernel boot parameters which avoid starting a custom or modified ROM. This is one of the examples I fixed as you can see in the kernel thread and the reason why the modified stock ROM from @joel.maxuel is booting.
The multirom thingy (you may point to) was about having a special boot image (based on TWRP) named multiROM. With this it would be possible to power on the device and choose different ROMs you may have installed (that means different ROMs on 1 device in parallel). Great thing and at the time of writing one thing I tested. The main problem here is not using the Loki patch mentioned above but instead the /data/media internal storage which need to be mounted correctly and some other things as well. Nevertheless is multirom nothing I want to work on atm because the main part of work is to have CM/AOSP compiled and working.
what was the point of labeling this thread? gain some thanks by saying you spent 200+ hours on compiling the stock kernel source that has a guide to compile it in teh source zip?
Click to expand...
Click to collapse
I never said that I spent 200+ hours for compiling a stock kernel. Please read carefully before getting rude. This thread here is for developing on the F3Q ROM not the kernel. Kernel things are located in the Kernel thread. (Btw. compiling the stock kernel was never a problem or somehow time consuming there are other things like the initial ram disk and correct mounting paths etc which had taken some time but that is another story and as said not related to this thread.)
You may have heard about people porting ROMs to new devices? I try to do so and that is the reason why this thread exists. Not for some thanks clicks - some people define their self not with this you have to know. To be honest I do not get paid for everything here - which is ok. So a thanks click is appreciated, of course. Nothing more nothing less.
btw: I believe that a user can decide on their own if they want to click thanks when they want right? TWRP and Kernel are both things ready to use and the ROM porting is a WIP which a user can or can not say thanks for. That should be decided by the user IMO.
instead you are pulling in search results giving false hope to people looking for cm in hopes they donate to you so you can buy a phone when you obviously dont understand how it works.

To be honest it seems obvious that you do not understand. That is not a problem because I can explain it to you again.
As stated before and in the OP I try to port AOSP and/or CM to this device. Well it is true that I'm still learning and will learning forever but that is the truth for everyone (maybe not for you, ok ).
The donation part is something which was an offer to continue the work because I do not owned the device anymore but I was and I am willing to continue. As stated in the the donation thread I do not use the device for anything other then development because I do not really like the phone itself. But my wife uses the phone and she needs CM / AOSP to be able to be fully in German language and having a smoother Android experience than with the stock ROM.
If you know everything better than me then why you do not share your knowledge so we can speed up the process of porting? Would be more efficient than writing

The following has been done 10 minutes ago:
adapt DM47021 DT (device tree) to F3Q and compiling CM KK systemimage/full otapackage
This is 1 step further into the right direction but do not expect too much it simply means that I was able to fix all the thousands of compilation errors for the new adapted device tree.
Which is GREAT, of course but now the debugging starts and recompiling etc ..
The first boot was a mess I believe it has to do with a wrong used gcc version but I need to investigate that further in the next days/hours whatever..
just wanted to keep you updated

My hat is tipped to you xdajog. I'm looking for a qwerty slider replacement phone for my wife as her current one is reaching 5 years old soon.
Your efforts have tipped me towards this phone as a working ASOP or CM would be necessary as I do not think this phone will be updated by anyone else. I'm always leery of putting a family member on anything past a feature phone unless I can be confident of keeping it patched. Since there are no flagship phones with qwerty keyboards the efforts of devs like you are all the rest of us have.
@xdajog than you truly for your continued support on this device, i am a late adopter to this phone but is there any hope for getting android 5 on it?

yes, but the lg optimus f3 and f3q have the same specifications and the same kernel, the difference among them is where it was manufactured and the f3q comes with a keyboard and different touch buttons, take a look at the comparison below:

Of course. Thats the reason why I use the F3 device tree as base for development. But there are many differences in compiling. If you want you can try would be nice to have another dev here.

Yeah, i will try, give me the a one time
So I've got an Ubuntu 14.04 LTS VM set up on my machine and I downloaded the Android source tree (AOSP) and configured the build environment per the instructions. I ran a build and everything came out okay (but slow ). I have some additional RAM on order for my machine so I can dedicate more resources to the VM.
I have an extra F3Q I can use for testing and I have a pre-paid SIM on order so that I can actually use my test device in real-world scenarios.
I'm ready to start digging in here. :good:
Edit: RAM arrived today, have 32GB now which means I can dedicate a full 16GB to the Ubuntu build environment!
I have created a mostly-functional build of OmniRom 5.1 (Lollipop) for the T959V
However, I don't have enough posts to post in the development section or to put in links. Does somebody want to do this for me? If so, let me know.
The current status of it is:
What works
Taking pictures (very laggy switching between FFC and rear)
RIL
SMS
Data
Recovery
Bluetooth
Wifi
Vibration
Powered-off charging animation
Flash from BML
What is definitely not working
App to SD - not working on i9000 either, complains about insufficient space fixed in git
Tv-out as Omni's aries-common has removed it
Video recording - only captures fuzz fixed in git
What is untested
Everything else
What is probably not working
Microphone mute option doesn't work during calls - not working on i9000
GPS - I actually have a T959P, not a T959V... It was released by Telus in Canada. It is a very similar device (I can run ROMs for the T959V with limited problems - ie sometimes I get wakelocks and the gps never works), it has a different GPS chipset (hence why I have no clue on the status of the GPS) and also uses different cell bands (but I can still use your guys modems but I lose access to the 850Mhz band). I have created a build specifically for the T959V as best as I can guess from teamacid and others' device trees.
Selinux is set to permissive as I don't know how to create the proper policies for the GPS.
For a download and more information, see drive.google.com*open?id=0B7vXjzo0Hj-ifm1KQWNYam9FYWdnaFlXZU5LVnVVSzJxYVU3eHlWZGR1VVNZUWk1V1QzOUk (replace "*" with "/")
Source code can be seen under my github account (username is xc-racer99 there as well) under the android-5.1 and android-5.1-t959v branches
Ooooomg ...im wait ....is amazing the new proyect .....thanks thanks
Quick update:
I've got the video record to work properly now as well as being able to move apps to the SD card.
Selinux is left!
Should I upload a build?
Sure...I have a spare phone somewhere that I can test it. Do you have a Gapps package to go along with the ROM? As far as GPS is concerned, back when Beanstalk 4.4.2 was being worked on, a patch was developed to make GPS work...I'll have to root around in my files and see if I can dig it up...I think the developer deleted all the Beanstalk threads for some reason or another.
Yeah, I took the GPS files from CM-11.0 but I can't test if they work. With regards to the Selinux portion of things, only some parts of it were being enforced in KitKat while everything is now being enforced in Lollipop. GPS was not enforced in KitKat so the policies for it were not in place.
I haven't tried any gapps on it yet but I would recommend trying any of the three from the Omni i9000 thread
forum.xda-developers.com*galaxy-s-i9000/i9000-development/rom-t3054101 (again, replace "*" with "/")
I'll upload a new build as soon as I can verify that it boots - it fixes several issues such as apps2sd and camera that weren't working in the one I already have uploaded.
Also, I'm curious as to what the command "cat /sys/class/sec/gps/hwrev" shows. In CM11, one of the GPS files check this and depending on what it shows it loads a different file. Does this mean that there are two hardware variants of the SGS4G?
Alright, new build uploaded. Follow the "link" from my first post, the build is under the Galaxy S 4G (T959V) folder. Selinux is still disabled, no extra policies have been implemented. Apps2sd and video camera should work.
For flash instructions, just do a data wipe beforehand. You should be able to flash from any CWM 5.0+ or TWRP, regardless of BML/MTD status
Been looking at the gps a bit more, seems that TeamAcid's CM11 did it slightly differently than most other KitKat roms in that it has both a gpsd and a samsung-gpsd. Do you know what beanstalk used? It would be so much easier if it didn't have the samsung-gpsd... However, we still have the funky init.d gps script which checks the hardware revision....

I was using Google Drive as its something I have an account for already and has plenty of space on. Do you have a suggestion of a site I should use? In the meantime, a direct link to the file is https://drive.google.com/file/d/0B7vXjzo0Hj-iZ0YtQTdoTG5KVW8/view?usp=sharing Hopefully this works...
Google Drive isn't bad at all. I was suggesting that you use another cloud service for uploading the files if it didn't work. (which i didin't do a really good job telling you that)
Thanks, that link works!
Alright, I have opened a devDB thread at http://forum.xda-developers.com/gal...official-omnirom-5-1-galaxy-s-4g-sgh-t3146611

***/
iPioneer Slim 10c v0.1 is a light, clean and fast custom rom designed for the Lg G Pad X 8.0 (T-Mobile variant only) and it's aim is to become a replacement for the default system of this device.
iPioneer Slim 10c v0.1 it is light because it only takes 519.8Mb of disk space which is a big difference when you compare the 1.2Gb of a stock rom, it is clean because it only contains the essential apps to make it work properly and it is faster because the whole system have been 100% optimized.
iPioneer it have been designed with the User Freedom in mind, it only provides you with the basic OS so you can do what you need to do on top of that.
Features:
Based on stock (10c)
Rooted
Busyboxed
Init.d Support
Extremely debloated (very serious)
Deodexed
Zipaligned
Nova as default launcher
Installation instructions:
Download the rom to your desire location (link to download to the end of this post).
Boot into Twrp recovery and do a standard wipe (factory reset).
Install the downloaded rom .zip.
Reboot the device.
Be patient, is going to take more time than a regular stock rom to boot into the system, at first is going to be stuck at T-Mobile logo but after few seconds is going to enter into App Optimization mode and after that you will be able to setup your system.
Enjoy it.
First things to do after you install this rom:
Add your google account (if you didn't complete that step at the first setup).
Download your favorite app manager (Rom Toolbox, Titanium, etc.).
Freeze the application called App Updates in order to stop the system update beacon for OTA. I removed 3 core apps in order to stop OTAs but it seems to be very integrated with the system, there is no way I can remove it from the rom without breaking the system. This is the most practical way to my knowledge right now.
Optionals things to do after you install this rom:
You can uninstall Nova Launcher if you want as is not part of the system apps, but before you need to install your favorite launcher. If you don't install another launcher and remove Nova you will have a broken system and most likely you'll have to re-flash the rom.
On purpose bugs and missing options:
On purpose bugs are bugs that comes when you remove a functionality from the system but it can not be removed from a third party component, example: LG VPN app it has been removed but the options remains in the Settings of the device and when you tap that option you will provoke a crash event, the way to resolve this is to decode the third party component (very difficult) or reinstall the missing part (in this case the LG VPN app).
iPioneer Slim 0.1 it comes without some apps that can not be removed from the system setting options, this is like that because I believe that these apps are not necessary for all people, if someone need them they can be downloaded/replaced from the Play Store or I will provide a flashable file with these apps so you can install them.
On Purpose bugs (located at settings):
From the Share & Connect menu:
File Sharing that contains BLE and Android Beam doesn't work, package SmartShare it has been removed.
Media Server (DLNA) doesn't work, package SmartShare that also contains SmartShare.MediaServer it has been removed.
Lg Airdrive doesn't work, package LGAirDrive & LGAirDriveSettings were removed.
From More>VPN menu:
LG VPN doesn't work, package VpnClient_LG it has been removed. Basic VPN it works.
From Display menu:
Home screen doesn't work, packages LGHome, HomeSelector, LGHome_Theme_Optimus, com.lge.launcher3, com.lge.launcher2.theme.optimus were removed.
If you need these options to be available on your system just download these app on Play Store if they are available or just wait until I have ready the System Apps flashable zips.
Missing options (located at settings):
Smart Cleaning not present, package LGSpringCleaning it has been removed.
Cloud (cloud integration in settings) not present, package CloudHub (maybe dependant on SmartShare package) it has been removed, please also note that this cloud integration it was integrated on the stock File Manager, so... if you want a full integration of the Cloud service on settings maybe you will have to install the stock File Manager provided by LGFileManager package.
From Backup & reset menu:
LG Backup is not present, packages LGBackupLauncher and LGBackup were removed.
From About tablet menu:
Update Center and its content (App updates & System updates) is not present, packages com.lge.appbox.client (app updates), com.lge.updatecenter & LGUpdateCenter (main menu for updates) were removed.
If you need these options to be available on your system just download these app on Play Store if they are available or just wait until I have ready the System Apps flashable zips.Flashable zip with system apps:
Coming soon when I have a free time.
What to do if you get the OTA notification:
Freeze the app called App Updates with your favorite app manager.
With your favorite file manager go to /cache and delete the update.zip (the downloaded ota).
Tap on Restart & Install button on OTA pop-up, the pop-up it will start counting to 0 in order to restart but your device won't restart because there are 3 core apps removed from this rom plus 1 app that you just disabled (all these 4 app controls the OTA), the notification is just gonna disappear, push recent button and clear the ota pop-up window.
Bugs Report:
If you find a bug in this rom just notify me about that in this thread, please, just use the title as "Bug Report" so I can pay close attention to that, my time is very limited. Thank you.
Feature Request:
If you want a feature to be added into future revisions of this rom just notify me about that in this thread, please, just use the title as "Feature Request" so I can pay close attention to that, my time is very limited. Thank you.

How fast it can go is a subjective matter:
It will depend on hardware lifetime span (how you use it and how other people use this tablet).
It will depend how much apps and content you put in it (the more things you download the more slow android is gonna be, this is kind a Swap area).
I did not do a benchmark, when I declared that is faster than a stock rom is because that speed response enhacement it comes based on the Deodex and Zipalign process. It can be or maybe not noticeable to your eyes but based on deodex and zipalign process is for sure that is faster than an odex and not-zipaligned rom.
The best answer is that you need to try it on your own and see the difference.

Poll added at the beginning (not visible in tapatalk or xda app).
Please only select the apps that you really need or you really think that should comes with the next revision of iPioneer Slim rom.
This will help me to build a better version with features that users needs.
C'mon guys... only 3 users have use the poll...
I need more data background in order to release a new version of the Slim line version (may be the last one).
All V521 users please contribute with this.
Right now I'm testing a new build that it seems to have success stoping ota download and notification & I have removed even more bloat background packages.
As of today I start the syncing process of CyanogenMod for our device, so all I ask is that V521 users vote in the poll so I can build and release what I think it would be the last Slim version (iPioneer Slim 0.2) based on users needs.
Once I start the developtment with CM I will not pay attentions to the Stock & Slim version until I finish with what is gonna become iPioneer CM 13.
Thank you for your attention guys.
BTW: sorry for my english, I try so hard to write all this in a good way. Arriba Mexico Papa!!!

The reason is that the xda app can't see the vote going on.
Personally, I will be excited to see a cm/aosp custom build, which will sure draw much more attention.

Another reason is not many users are interested enough in a slimmed stock rom. The benefits of a slimmed stock rom may include less system storage usage. But the free uped system storage is not accessible for users to use as data storage anyway. Speedwise, I wouldn't expect noticeable improvement from a slimmed stock rom. As a result, the benefits of a slimmed stock rom is not enough to draw users' attention or interest.
I am a flashholic but I actually not interested in slimmed stock at all because I already have root.
I personally advise you to not spend too much time on modified stock rom.
I appreciate your work and look forward to your future possible cm rom, which I will definitely try it out and will draw many g pad x users here. And don't forget there is a bounty for custom roms like cm.

You are right about working in a stock version. The reason why I'm doing this is because we all know that CM most of the time has bugs, bluetooh problems, camera issues, data conectivity troubles, etc...
Sooooo, if the version of CM I'm going to compile it results with many bugs there is gonna be the option to go back to stock slimed or stock bloated.
I can build a CM verion but Im not the kind of guy who inverts his time in CODE MODIFICATION, so hopefully the build it comes with no bugs at all or at least no major bugs.
The other alternative is that I can sync, compile and build and one more guys can do the bug fixes.

That would be great! I think if you took a poll most people would prefer a CM build to a slimmed down stock build.

Yeah, I know that. Wish me luck.
Right now I'm stuck trying to get the Blobs for this device and compiling the kernel so I can build the CM recovery, once I have the recovery done I can start compiling CM and start testing.
I'm trying to by pass the kernel (as is not need it right now to build the recovery) but for some reason the system is demanding an standard and working kernel... weird...
But honestly speaking is gonna take lot of time. So be patient guys.

There is already a TWRP recovery for v521. Why you need to compile cm recovery?

Ik, is just a prebuilt because our device doesnt have a device tree or structure already, so making this at first is gonna help me to buil the cm zip.
Is not need it if a device tree already exist but not in this case, just see it like a pretesting of code for this device.
When I try to compile this recovery things are gonna break so you get info of what is missing, what you need, log, etc... So you fix everything you can in this step and then you build the cm.zip in a better way (less issues).

device tree has been around for a while, it obviously will need some renaming to work for cm source but its a good foundation to start with.

These are your device tree for twrp 4 b3 right?
Let me see if I can work with that, I was almost done building the cm.recovery and fixing some boot.img issues but if I can take your files that would save time.
Did you forked that device tree or u just build it from scratch?
If you forked them, from what device?
I was thinking on pulling the v500 just to figure out some sort of missing info I havent been able to catch from ramdisk.

i built it from scratch, id be careful looking too much at the v500, it's a snapdragon 600 SOC which is very old and is a quad core. the 615 in the g pad x is octacore and much newer. even the ramdisk is going to have big differences in how its handled.

• Added Vilte to /etc /bin /lib & boot.img
• Added hd voice calling
• Added Dual mic support
• Added NFC compatabilty
• Changed some cam libs to clean the picture up, touch to focus works camera quality is on par with stock if not better.
• Ril optimisations, call quality is now same as stock
NOT WORKING
• Vilte, driver compatabilty issue trying to fix may work partially
• NFC, im working on it for now everything but the running app has been placed.
• FRONT CAMERA DOES NOT WORK
dont ask me to fix it, i will decompile the kernel when i get free time to do so to try and fix,
ive already chowned & chmod'ed init.rc & init.mt6735 with drivers from stock, switched to running through mediaserver instead of cameraserver in service_contexts as it does on stock, created an init.camera.rc to enforce the stock camera permissions, switched each lib out individually leaving only those that dont break the camera, switched camera.mt6735m out in HW aswell as the mtk_camera_clientand it still dosent work i will continue to work on this problem until resolved
Nice job with the ROM, mate. I presume you're Australian, right? Had to mention it based on the Optus reference so yeah.
And care to expound on decompiling the kernel? I presume you can deduce what's going on with it so you could build an equivalent kernel using extant sources, yes?

Hey mate sorry for late reply, been finishing a ubifs cyanogenmod 11 build ive jjust released,
Cheers for the feedback yeah this one is for alcatel 5044T using kernel 3.18.19+ great rom though just havent gotten round to decompiling kernel to fix the front camera managed to interpolate the back though to be better than stock
I use a .sh file called kernel-decompile.sh usually but havent decompiled a kernel in a while i try to use stock untouched as it saves the headache of getting kernel readable to make changes,
Did you make any progress on your build yet ? Managed to take a breif look at your device tree i noticed in one of the files it was screeming at the init.environ.rc is this present in your boot.img as its stating that the paths are missing for it if you have the init.environ.rc present you just need to add the paths listed into there corresponding path being either BOOTCLASSPATH or SYSTEMCLASSPATH
I noticed you init.rc is not right at all there is no information within to run any of the /bin resources required to execute gui, post fs-data section is also missing aswell as setting up the global evironment was also wrong i beleive as there was no info for chowning or chmodding below the mkdir asserts,
Ive still not looked at alot but everything else that i have managed to look at seems to be pretty good
I should be hopefully getting my Lineage 14.1 build up for the alcatel pixi 3 using stock 3.4.67 kernel soon so you may be able to see how i made the boot.img and compare it yours if you want or i have my LineageOS 13.0 build already up for the Pixi 3 already which uses the same setup pretty much because afaik the way the fs setup is set it out in the fstab and init.rc is all the same from 5.0+ onwards as it uses encrypted footers and what not, i had to vold manage the 900Mb /custpack partition to be used as user accessible data for file transfers and general storage of photos videos etc as it would not mount any other way and would cause me infinite boot loop i had to also set the 3.6GB /internal storage as a voldmanaged user inaccessible partition reserved for system storage as the /system partition is only 512mb so ive been struggling for space to make everything work but its nearly done

And by init.rc do you mean init.mt8127.rc? Could you tell me which parts are wrong please, as I've based this off @Stricted's MT8127 repo. I doubt that the missing "LD_LIBRARY_PATH" is at fault too. Also, I am getting a missing "__umodsi3" symbol error prior to introducing a (rather pointless imo) shim just to sort of make hwcomposer happy, even though I still end up not getting the GUI to show up.
You mind if we continue on discussing this on the LeapFrog development thread though? I don't want to stray off your original topic here anyway.

Hey mate sorry for late replty been helping a friend out building a twrp for them,
Yeah ill go through your init now on your guthub and ill type out into a notepad++ what i can visually see is wrong with it and any other files also,
LD_LIBRARY_PATH i beleive wont break a system and shouldn't stoo GUI loading up, also with HW composer could you notjust disabling it to run native 2D graphics ?
Anyhow yeah ill jump on the leapfrog forum when i get some time

Hey buddy, hows things going?
I was able to fix the front camera in my rom a few weeks ago,
There is no need to touch the boot image or kernel, I also experimented with changing permissions of camera drivers in the init files to no avail.
To fix we must ignore the advice of every porting guide and replace more than one lib.
In the end I looked at similar mtk kernel sources and was able to trace the error back to libcam.hal3a.v3.so however just changing this lib is not enough, we must also change some of its dependencies. Attached is a list of 12 libs that I changed to solve the problem
EDIT:
It may not be necessary to change all of these libs, you may be able to get away with just changing the hal3a libs and featureio and featureiodrv as these were the last ones I changed, I didnt try taking away any of the other libs I replaced as I found 720p recording was better and general camera quality had improved

Hey mate,
Yeah im not to bad sorry for late reply ahh sweet that means i dont have to decompile my kernel now that may have been one of the libs id changed that time id gotten it working and didnt even know id changed it, how did you figure tthat one out, as usually for cam the mains are camalgo, camdrv, gralloc & featureio i couldnt wrap my head round why i couldnt get it working again lol
Yeah 720p i found was the best optimal setting as SS 480p seemed to be a bit grainy and 1080p isnt device supportive so is so slow i havent released an update to CRdroid so may end up getting it done in the next few weeks 5044T users will be happy great work on figuring it out

I am not sure, something's keeping the loading animations from showing up, maybe I might have missed a few more blobs or whatnot. I'll have to upload an unsigned dump of the Epic for you to peruse some time. You mind if we get you a donor Epic whilst I wait for mac2612 at /r/OpenLF to get his own Epic being he's had Linux development experience before.
user154 said:
So I looked at logcat and saw that the issue was lensdrv looking in the wrong place for the lens. so I looked at some mtk kernel sources to see if I could trace lensdrv back to a specific lib. It appeared to be part of hal3a however changing this lib would make the camera app disappear, so I tried installing a different camera app which failed to install. when I looked at logcat the install failed because native libs were missing so I used a dependency viewer to see what libs were dependencies of hal3a and began changing them one by one, focussing on drv libs and then testing. Looking at logcat after I had changed a few I saw a reference to a problem with featureio so I opened featureio and featureiodrv in a hex viewer and one of them (cant remember which) had a string specifying the lens location, so I added these two and the front camera worked. This is what makes me think you could maybe get away with just changing hal3a and the 2 featureio libs to get the front camera working, however I was happy with how the camera was working so didnt try to take away any of the other depdencies I had changed

Hey bud sorry for the very late reply i feel quite rude i somehow managed to unmark my own thread just scoured my mentions section looking for a comment on it lol,
Had troubles with pc also blowing just got it fixed today so looking forward to getting camera all working well with it managed to make some progress with my rom before it did though
Ive turned my build into a vendor image as im also trying to incorporate all the test tools from the stock rom aswell as the VOLTE modem thats been attached to custpack in stock,
Managed to get most test tools working well but something wrong with the modem not engaging properly it says YES OPTUS but has no signal or service and imei is also blank not invalid but blank & gone lol yet sim still registers optus so i think im gonne be doing some debugging on it to see whats going wrong ive got a feeling i may need to reverse engineer the modem libs hoepfully not other than that ive only got a small bug when it first boots up that states "a vendor image mismatch has been detected, typically this means your vendor image is out of date please ensure your vendor image matches NJH47F"
Got me stumped a bit on it as i cant spot anything obvi wrong but ill persevere as having it as a vendor build seems to use at least 60-100mb less ram, first boot is quicker & there is virtually no lag at all compared to a traditional build and i was able to add all the SLPencryption and Fpsv files and libs without getting a bootloop as im trying to get encryption to work with it, not sure if its working though as i didnt get a chance to test yet.
Ill keep you updated on progress anyhow as i go when i get round to it i gotta help blake first though as i promised him id help him get his CM 12.1 working when i got my computer working again as hes been dying to get it working on his leapfrog epic
Hows things on your end with your rom ? Did you manage to make any progress with getting IMS, VOLTE or VILTE anywhere near working im struggling to say the least with it lol
MTK source code
Hi @Matty1993
Not sure if this will help but I have found the FULL Mediatek source code for the MT6737x.
The Android 8.1 sources can be found HERE along with some other useful things like the Android SDK source (This is the full 6.0 source code). :good:
I have downloaded the 8.1 source and it seems to be complete.
There are also full build instructions although you will need to create your own "Build Project" from what I understand or maybe you can just cherry pick what you need. :fingers-crossed:
Below are the officially maintained repository's on github.

Hey, dont feel rude we cant all always reply straight away I've just welcomed my 2nd son into the world so not really been on here very much over the last month or so.
How is turning your build into a vendor image going? I didnt think this device had a seperate vendor partition just a sub folder of the system partition. If youve managed to give this device a vendor partition that would be quite a feat, theoretically it would mean it would be able to boot a GSI although I dont know how much mileage you would get out of this in reality.
I would imagine some of the problems you are having would be due to the system expecting files to be in one place but you have them in another, you should be able to work this out from the logs though if this is the case.
Good luck to the pair of you on the leapfrog epic front, sounds like a very fun project
I havent done much more on my ROM the only thing left to fix is IMS/VOLTE but I cannot test this so without having someone to test it and provide logs there isnt much I can do. I've been looking round for an oreo rom to port from but thanks to TCL deciding to compile the stock rom as 32 bit and not 64 this is proving rather difficult. I have looked at the possibility of porting 64 bit rom to 32 but from what I can tell the chances of ending up with a decent port rom with no major bugs is pretty slim.
At the moment my main project has been making a game for/with my eldest son, he is obsessed with kirby so made a simple platformer using sprites ripped from various kirby games.

Havent worked on the build in a while been in hosptial with pneumonia horrible just horrible wouldnt wish it upon anyone, before hand though yeah vendor build was going great so much more can be added and works where it dosent in /system, such as the slp encryption and cloud test suites etc would all give me bootloop when added to /bin /etc and /lib so what i did is made the system think its got an emulated /vendor partiton instead of me going to all the trouble to create a logical /vendor partitiion by editing a few things in the boot.img .rc files and slinking it in the cpiolist so that the dir is set in the rootfs with 0644 permission but still using 0755 permissions in /system/vendor took me a while to figure it out but even makes system boot and run faster and smoother dont know how thats possible though as it even uses 100mb less ram deffo works as /vendor but as the message i stated in the earlier post just wont go TF away no matter what i do lol,
Still fixing front camera trying to compile my own camera lib for the front but havent gotten round to it yet

Hi @Matty1993
Not sure if this will help but I have found the FULL Mediatek source code for the MT6737x.
The Android 8.1 sources can be found HERE along with some other useful things like the Android SDK source (This is the full 6.0 source code). :good:
I have downloaded the 8.1 source and it seems to be complete.
There are also full build instructions although you will need to create your own "Build Project" from what I understand or maybe you can just cherry pick what you need. :fingers-crossed:
Below are the officially maintained repository's on github.
OrangePi 4G-IOT
OrangePi 4G-IOT build on MTK6737 Soc, the officially maintained repository as follows:

Sorry to hear you have been seriously ill with pneumonia
I thought you had gone kind of quite on the forum, I do hope your all sorted now and feeling better. :fingers-crossed:
Yes the source is probably the best I have seen thus far and providing you have the necessary drivers and a little know how I am pretty sure you could bring up a new Project for your own device. :fingers-crossed:
Not sure about your booting issue as it could be just about anything but I am sure you will hunt down the problem. :fingers-crossed:

All good dude yeah lots of nasty stuff in my lungs i got the privledge to know what a tube being stuck down your throat to make you breathe felt like yeah ill be sure to check it out as ive looked at a few but none of them were by far near complete which is probs why i couldnt get oreo to boot,
optus have finally switched to Qualcomm's snapdragon so they can run 8.1.0 on there new updated Optus x spirit 2 so they even have abandoned mtk i on the other hand prefer the overjoyable mess that mediatek is haha yeah thats what i figured about the boot issue to could be an init.xx.rc or se_contexts or even the init possibily everything else is perfect in bootimg, either that or could be one of the binaries in /bin or .jars in /framework could even be in /lib ill just keep picking away while i go through the oreo source until some magic happens :laugh:

Yes most definitely not a good experience I am sure. :crying:
Hope you work out your booting issue :good:
I may need to pick your brains later on regarding the Lenovo TAB2 A10-70F/L I managed to get the KK 3.10.65 kernel source to build without any real errors but I think it maybe arm rather than arm64 IDK the old style MediaTek layout is very confusing and I am not sure how it all works eg which parts come from the actual kernel and what comes from the Mediatek project which config's it use or how to make config changes even etc etc.
I have had a lot on recently so not really had time to fully explore it Github lenovo_kernel_a10-70f
I can't seem find any good guides for working with this old style layout unless you know of any. :fingers-crossed:

Yeah was horrible, made some minor progress on the boot issue dosent switch straight off now is sitting on logo for about 30 seconds before it switches off so getting there bit by bit haha,
Never worked on a lenovo Tab 2 what MTK specs is it running ?
your correct to also about it being confusing the word id use is uniqe experience to say the least last time i worked on older style mtk sources however i did make some notes as i got stuck a fair amount of times aswell not knowing where to put things but it varies from source to source where things go and configs etc etc so i dont know if the layouts would be the same

The tablet is based on the mt6752/6732 chip set (Quad Core) although Lenovo's specs say HERE
WiFi: MediaTek® MT8165 64-bit 1.7 GHz Quad Core
4G LTE: MediaTek® MT8732 64-bit 1.7 GHz Quad Core
The kernel will boot on either device WiFi or 4G so clearly not much difference between them and seems to be more of a naming thing and possibly some minor tweaking.
The Lenovo K3 kernel source is called the aio (All in One) so I am thinking it may well build for this Tablet too as all the drivers seem to be present in that source. android_kernel_lenovo_aio_otfp I just need to workout the defconfig and what device specific parts I need from the tablets KK source code.
