KitKat on custom device - Android Q&A, Help & Troubleshooting

Hello,
I am pretty sure this is a fairly common question and everyone would like to have kk on his device. I can use google to find out most of the tasks i am about to do, but i have to ask first.
I have a pretty anonymous device, a Chinese phone, rebranded in Europe. It features a hardware similar to this: mediatek MT6577
However the manufacturers only released a 4.0.4 ICS Android for it, and the comunity managed to develop a 4.2.2 JB. It is important to know that other manufacturers have rebranded this phone as well.
It is known as Allview p5 duo, Fly IQ441, and other brands.
What would i need to make a kitkat image for this model? How hard is it to "port" a 4.0.4 kernel to 4.4? What tools would i need, and also what knowledge?
I hope some dev sees this post, sheds some light over the issue and points me in the right direction. I really want to learn about Android OS developement and i feel this is the best way.
Thank you !

rk3026 Custom Rom

Hi
Welcome to what im hoping will become a popular project amongst owners of Rockchip devices. Over at rkDroid we are aiming to create the first custom rom for the rk3026.
We really are starting at the bottom with this one as there is so little info available about these devices. The aim will be a 2 stage project :
Stage 1 : Cooked stock rom
Stage 2 : KitKat
We want to get as many people involved as we can. This means addressing ALL levels of skill. This is why there are 2 stages.
Stage 1 :The 'cooked rom' - This will be for beginners to contribute to. It could be themes, app suggestions, tweaks, etc. They all go into a custom rom and no one is better than another. Anyone can get involved, even if they dont have a Rockchip device. Icons, Themes, etc. They ALL count.
Stage 2 :'KitKat' - I have the source for the kernel and Android build for KK on the 3026. This means we can (in theory) build KK for it. Rockchip released a press release a few months ago saying the 3188 & 3026 WILL get KK. So far the 3026 has been lacking in this. rkDroid aims to bridge that gap and get a KK build out there for these devices. Im no pro when it comes to building Android or kernels. Ive done a few but im in no way a 'guru'. Im also not stupid. This stage of the project WILL require people with some knowledge of building Android, etc.
Overall, the aim of rkDroid is to bring Rockchip device users together to share info, solve problems, build roms, etc. Our site aims to be a popular resource for Rockchip tablets (No TV sticks or Mini PCs yet, sorry guys).
We dont only support the rk3026, We also have info/roms/etc for the other Rockchip devices like the rk3066, rk3188, etc. We will be aiming to create roms for these too once we get more support.
The bottom line is that if you own a Rockchip device and want to be involved in creating a custom rom for it then get involved with us. Whatever level you are at you can have an input in this project and we welcome everyone. n00b or bo$$, its all the same to us, There is a place for everyone at rkDroid.
Let us know if your interested in this project and lets see if we can beat Rockchip by getting our own KK build out before them
did this rom can change size storage sytem
in fact on rk3026 MD706B tablet 8GO/1Go
we have
1 Go for system
1Go for internal sotage
and 5.6 for internat SD : nand flash
can we use 1 giga from those 5.6 to add them to internal storage like on samsung 16g tablket hey have 3G for internal storage

I flashed your ROM from rkdroid here with 3.0.36+([email protected]) #69 kernel. Rom is really fast but only problem is that wifi doesn't work. If I try to turn wifi bar on it will automatic slide to off position. It says that "turning wifi on" but nothing happens. I can't flash my stock rom back because my TWRP backup is corrupted (system part is missing).
Can you help me?
Solution: Turns out that that my wifi is actually Atheros AR9271 so all I need to do was flash Oma Cube U25GT2-H JB v1.0 rom with my genuine kernel. Everything is working now!
please help me...... i have supertab r10 rockchib rk3026 i flashed him then it become working whithout screen...... do you have any soluation?????!!!!!!
You should flash original firmware if your tab is bricked. Which firmware did you flash? Seems to be kernel related.. Did you make a backup before it got bricked?
i tried every flash at "wwwrockchipfirmware.com ..... and still the same problem ...... whait screen ore black screen ...... i did not make a backup ...... do you have an original firmware ore any solution for this problem
Hi all anyone can help me please? i have an INTENSO TAB 734 "7" inchs ARM, Processor Cortex-A9 with Rockchip RK 3026 Risolution 1024 x 600 Pixels, RAM type DDR3-SDRAM ,ram memory 1 gb......................

"Upgrade" stock 4.1.2 ROM to 4.4.2, possible?

Hi guys,
I just wanted to know if it was possible to upgrade a ROM (for the Huawei Ascend P2) from version 4.1.2 to either 4.4.2 or 4.4.4 or something similar.
As you may know no one has developed any custom ROMs for this phone and at the moment we have nothing more than a P6 ROM running on the P2 (which excludes functionality of getting signal, speaker audio, headphone audio and lacks the functionality of the actual buttons on the phone, the ones below the screen)
If this was possible could someone give me some pointers on how to do it? All I need is like a reference guide or tutorial.. I don't mind doing the work myself as I want to get into android development. I consider this my 1st project.
Thank you.

Most likely Huawei never put out the source code for it meaning unless there is a sister phone to it you can port from then not much else to do.

[Q] Upgrading a Handset OS from ICS to Jellybean

I might be talking out of the sky, but here it goes,
I have a handset Xolo X900 which was abandoned and I want to help out everyone whose Handsets were abandoned by the Companies but still able to run on latest Software so Here is my General Question
Suppose I have a Set with some version of Android and I want to upgrade it to latest , but the Phone Hardware vendor wont release it or upgrade it.
I want to be able to use the Android Source Code from Google to create a ROM or an Upgrade and bring the Handset to the Latest Version
I suppose It needs a lot but would be helpful if get some guidance from the Community to be able be free from the Vendor provided Updates for our System ,
I am ready for a Deep Dive to achieve this , but not able to find the correct Tools or Guide. , Please advice

Yes , its an x86 Android. I wonder if I can flash latest Android on it.
Its far fetched, but I wont mind trying if , someone hints on where to begin.
Custom rom will the biggest issue.
I have not found much resources on how to build one. Just couple of people who launch it and then we all use it.

[noob questions] ROM/Kernel - building/porting

I’ll start by admiting that, in the arts of cooking/building/porting android innards, I’m closer to being a complete noob than na intermediate user.
I own a Newman K1S, JB 4.2.2, MT6592, 2Gb/16Gb, 720p, and, sadly for me, it looks like the manufacturer (Newman Mobile, or Newsmy, who knows) pretty much disavows any knowledge of this model ever being built or sold. No reference to it, no community, no android updates or ROM releases.
Taking into account some MediaTek source codes for KitKat were made available earlier this year (even if unofficially), I was wondering:
So, question number 1 – Is it possible to build android 4.4 for my device straight from said sources? Or are they unreliable and it would be best not to attempt it?
And question number 2 – Being at the noob level, should I stay away from such a task? And, in this case, would I be better off porting a 4.4 ROM from a similar spec’ed device?
Also, while browsing needrom, I noticed that a 4.4 “official” ROM was posted for my device. However, having flashed it, I found that it produces no sounds from the external speaker (although with headphones it works fine). Same thing was experienced by other users, and there is no fix so far.
Which takes me to question number 3 – What may I try, in order to fix an issue like this? Does KK use the same sound drivers as JB, and maybe it’s only a matter of replacing them? (if so, I believe this is within my grasp, even if I must unpack the IMG files to reach the drivers)
Lastly, Newman K1S has a severe overheating problem when pushed, which I believe would be easily solved by underclocking it to 1.3 or 1.5, or maybe implementing an optimized kernel.
Final question – How do I manage to underclock with my current kernel, or, better yet, how do I port a custom, optimized kernel to my device?
Congratulations to everyone who managed to read this far, and thank you in advance for any help provided. I’ve spent the last few days reading tutorials and guides, only to become even more confused… I did manage to get android kitchen running on my Windows laptop, though!
Links to recent/updated guides that might be useful are appreciated, too.

I've successfully rooted my Leagoo T5c, now what?

Hi everyone,
After a few hiccups, I successfully rooted my Leagoo T5c, thanks to the excellent tutorial posted here. The phone works fine, thank you, but now, I'd like to know how to proceed to, say, upgrade the phone from its current Android version (7.0) to a more recent version.
Where to start?
Since this phone has a Spreadtrum/Unisoc SC9853i SoC (Intel-based), I suppose the custom ROMs and upgrade possibilities are few and far between, but I'd like to give it a shot.
I'm open to ideas, tips, tricks, voodoo moves and Santeria incantations, but I'm still a noob when it comes to Android, so please, be patient, and methodical... :good:
@UglyStuff
If you can unlock phone's boot-loader then you should be able to flash any Custom Recovery and/or Custom ROM that's suitable to 100% to phone's CPU-architecture. Who is the supplier of phone's SoC isn't of any interest at all.
Hi,
Thing is, as I said, I'm a noob when it comes to Android, so I don't want to brick my phone by trying to make it ingest a ROM that's not suitable for it.
If my phone came with a MediaTek or Qualcomm SoC, I wouldn't worry, because there are plenty of ROMs out there, custom or not, to play with, but this Spreadtrum/Unisoc SoC is a thing of its own.
It's based on Intel's Airmont architecture, and few phones or tablets use it, at least this specific version (SC9853i). Maybe I just don't understand too well how a ROM is built.

For example, I found this article where they explain how to flash LineageOS 17 (based on Android 10) on a Panasonic Eluga Ray 800 that uses the same SoC as my Leagoo T5c.
The thing is, I don't know if this is transposable to my device, though the two share the same SoC. As I said earlier, I don't want to permanently brick my phone...
@UglyStuff
The mentioned Intel Airmount SoC's instruction set architecture is x86_64 , the also mentioned Intel Spreadtrum SC9853i SoC's instruction set architecture is x86_64, too. Hence in order to upgrade yor phone's Android you need a Custom ROM compiled for x86_64 architecture. GIYF ...
OK, but since this Panasonic and my Leagoo share the same SoC, they also share the same x64 instruction set, so do I get it right if I say that the custom ROM built for the Panasonic would fit on my Leagoo, or am I missing something?
In theory it should.
OK, I guess I'll have to chance it, and use recovery in case things so south. My phone isn't compatible with Treble, according to this app. Does it mean anything in terms of installing one of the generic system images found here or not?
