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..

Spent time = about 244 hours... any "Thanks" click still HIGHLy motivating..
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.

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.

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.

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.
Click to expand...
Click to collapse
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

......and another thing I want to mention today!
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!

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.

Too bad, a lot of people won't be able to see this rom, but I can do nothing.
If someone knows an admin who can fix this issue please make mention of this post to him. I would do it but I don't have the time to.

How fast does it run compared to the stock rom?

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.
