Hi Everyone!
I'm very new to this topic, this is my very first time trying to build a kernel from source code. As setup i've a samsung a13 SM-A135M (which is the 4g version of a13 series), this phone by default is forced to work 32bit on a processor and hardware that has the capability to go full 64bit.
The question is:
I've inquiried the correct version and baseband that corresponds to my device, on https://opensource.samsung.com/, and they uploaded the source code of it (the baseband is A135MUBU1AVB5), so with this source code should i be able to build a 64bit version of both kernel and android OS , or this source code only works for 32 bit installations?
Thanks and Regards!
Hi, I just asked a very similar question here: https://androidforums.com/threads/i...this-problem-a13-samsung.1347411/unread?new=1
And someone's reply brought me to your thread. I don't exactly know much about coding but an experienced user said he did some searching, his answer is on my thread. As of now there is no way that he could find to get a 64bit software on the a13, hopefully this changes.
Hi!! thats right, the problem that you have is what has driven this question, although i've the source code for building the OS i'm waiting for someone more experienced to tell me if this source is able to build a 64 bit version of the OS and Kernel for the A13 phone. Hope we find this experienced person

That would be great I think the a13 is great value for the price now we just need to get around the software limitations

Hey, so last year I bought a China-Tablet called Zenithink C91, it seemed like a good choice back then.
However, the software on it is rubbish. The manufacturer didn't even bother to change anything from the reference software for the hardware platform, did no optimization whatsoever. For example the build.prop is a complete mess with dozens of duplicate lines and references to the reference platform from AMlogic. All the stock firmwares have phone functionality enabled, even though there is no gsm module, showing an empty signal indicator all the time. Or the shipped ICS with gingerbread gapps and so on. The Tablet is just not usable in this state because the software sucks so much, and they do not answer any questions or take advice. Therefore, no sources.
However, I think the Tablet could be much more useful, because it has a decent cortex a9 processor which runs at 1ghz, and a mali 300 gpu.
So much for the situation.
So for a long time I thought about trying to compile a new rom for it, to make it actually work like it should, but I cant find any advice which would help me, because all tutorials that I find require me to use devtrees for devices that already exist. But how would I go to create Android for a device which has none?. I could probably extract most drivers from the latest ICS build. How compatible are they with JB?
On a side note, I wanted trying to Port CWM recovery, does anyone have a pointer where to start?
Thanks and I hope I did not post in the wrong section.
I actually think that there is a source available for your tablet. Check out Slatedroid, as it's a forum dedicated to chinese tablets.
The problem atm is the new version of the amlogic's platform for which they haven't released sources yet.
Oh, and tutorial for Clockwork recovery:
http://www.koushikdutta.com/2010/10/porting-clockwork-recovery-to-new.html
Thanks for your reply, especially for the link concerning cwm.
I am aware of the slatedroid forum, and a user there, too. Zenithink did not publish any sources, I am very sure sadly.

Zenithink maybe didn't, but you can find amlogic sources (the chip/platform manufacturer) here:
http://openlinux.amlogic.com/wiki/index.php/Arm/Android/2.Getting_the_Source_Code
edit: that is if they are using that as a platform ofc, if they're not well from what I see on slate you're limited to modifying stock roms, same as we on elf/aurora ii devices
Yeah, the stock sources are there, but ZT modified them and does not release the changes. No chance then, I guess? Anybody know if there is a chance for JB based on the ICS rom?
Hi there!

I dont think there is one for that as that is not an official version of Android. Very few China based Android phones are supported by AOSP. You may have to start it yourself if you want it. The first thing you will need to do is have the OEM post the kernel source code for the device. This will be your biggest challenge. As most China OEM dont respect the GPL laws

Ok
What if there is no source of kernel? Can I use compiled kernel (3.0.13) from current firmware (4.0.3) or this is impossible?

Without kernel source your kinda out of luck. No that kernel will not work on AOSP as that 4.0.3 is not an official android version. It is a hacked together version. Your best bet would be to sell it and get something that is not a knock off.

Just for fun: wrote to "developer" for sources.

Got to write to the OEM. Only they will be able to release the kernel source. Good luck. Dont hold on to hope though. They are not forced to post kernel source like everyone else.

Don't you know is it real to compile with another kernel for same CPU MT6575?
Found some links to kernel sources for other phones - seems to be working for different devices.
Hi Guys I Want Someone Who Can Help Me To Build CM For MTK6575 .
I Have LG Optimus L4 II E440 Its MTK6575 Based Device And I Have Source Code .
I Think It Will Work On Other Devices .
Even if you have the source code for that device, you can't just build generically for anything with that processor as even if just one part of the device is changes that part would probably cease to function. Also when it comes to building something like that I'll see what I can do once I have a fully functional computer but the source is like 40 GB so it would be a big investment already just to download it. Which version of cm?

I made some 1.5 based rom at one point for my g1 but I remember like...none of it. Once you read up on building android you should be fine. I'll just warn you you will be working with BIG data, probably around 40gb to download.

I'll have to see. I have hard drive issues so I couldn't do it myself but I think I can guide you to a few good guides. There's a really good xdauniversity one I saw at one point I'll try to find.
hello, so i have been in communication with huawei regrading the kernel source. i mentioned the lack of source files for the mate 7 and how its part of the google/android agreement that oems must share all relevant sources for devices that use any part of android. they replied with the usual reply about how they will work hard to resolve this issue and whatnot. the rep did give me a link to the kernel source which i believe is for kitkat but i cant be sure so i hope that someone can verify.
having said that, why cant the kitkat source be used to build for lollipop and marshmallow? im still using a nook hd+ that is running MM......... WHAT??? how is this possible if the only kernel provided was for ICS? anyway, im going to keep poking at them until they either give up the LP/MM sources of they tell me to ****off. so, if anyone can please check out the link i would really appreciate it.
Lollipop Kernel?
It's a mediatek processor and supports SPFlash byapss in case we screw up we can still recover...
Lenovo posted the 4.14 kernel, I tried building it and it seems to compile without any errors. Just need help getting the proprietary blobs and to build a device tree.
What's the model number of this?
I have a P11 TB-J606F
I am a developer, but I have no knowledge of how to extra the blobs ?
Can you post a link to the kernel sources ?

That is the snapdragon variant, likely much easier to develop a custom rom for...
I am talking about the mediatek one which is the cheaper model (although they call it "plus")

You can get the source from lenevo's open source website and search for your model...
There are scripts floating around that can help you extract the blobs from your running device or a system image.
You'll have to make a device tree though
Ah. OK
I noticed something on github about Levono not releasing the latest kernel sources in a reasonable period of time.
Current kernel sources for Lenovo P11 (TB-J606F, TB-J606L) · Issue #1 · lenovo/gplcc

And people just having kernel panic's after trying to use the old kernel, which appears to be over a year old

You might have a lot of work to do then. You can compare with other tablets with the same SOC. Snapdragon is very common and they release their own source as well and can rebuild the kenrnel.
You can use that guys kernel and see what the panic is to figure out what he is missing. It's def possible!

Yep. Probably a year old kernel should be fine, and the other guy's kernel probably has a miss configuration
anyone out there to test custom rom for P11 plus? I have compiled it but I haven't received the bootloader unlock email reply so cant test myself
Is LineageOS working on this tablet? I recently bought the tablet for my son (on a whim, without doing much research) obviously a fault on my part but i was hoping someone smarter than me got it working. I don't mean to come off rude demanding anything, just hoping someone has it working.
Can I use tb- j607 f android ROM on tb-j606f the only difference is the chipset ..snapdragon 775 and 662..the hardware the same ..please help
Cannot get android 13 for tb-606f please help
