IMEI corruption hasnt happened anytime with this rom, as ive been using it since v0.7. I experienced it when i tried to install a rom for a110 in Dec.2013 and lost IMEI....but just by flashing at the service center got everything back. NxtGen is very teasing and eagerly awaiting V2. Are we closer to Lollipop please, as a version is available for a116 and a117.

Hi i am ported cyanogenmod 11 next gen for general mobile disovery gionee e3 -& blu life play. İ used stock kitkat kernel & libs

My port have another problems

Reboot problem

Cwm install wifi not working but using twrp install working

Blu life play have kernel source for mtk 3.4.67 please update your rom & kernel to

Mtk based kernel

Quote from jawad6233

And This is The Kernel Source in Their Server...
[Miscellaneous Android Development] EnerJon:
Thanks for sharing yavuz brother, i am jawad... Unfortunately the kernel sources released by BLU are incomplete and all device specific drivers are missing... They are useless...

FYI, Chris is already using hyperion's mtk based 3.4.67 kernel... Otherwise it wasn't so easy to port using stock kernel like you and many other people did...

No one can help you here because you are posting in wrong section of xda and asking the wrong question dear....can you read the thread title!!...it would be better if you search before posting problem like this bcoz NVRAM partition contain information about IMEI of a specific phone which can only be used to restore on that specific phone...no one can share that for you bcoz its not helpful to you.

Since you had mentioned in ur previous post that 2g is working but 3g not then this means your nvram partition is ok...bcoz if its damaged then there should be no network at all...so restoring to stock rom should fix your problem. :fingers-crossed:

If no IMEI then consider the following threads:

new url + potential memleak fix

Hi,

download link updated (see op).

Please try to update the gralloc.mt6589.so (see op) in the rom to see if this fixes the stability issue.

Copy the file to /system/vendor/lib/hw/.

adb root
adb remount
adb push gralloc.mt6589.so /system/vendor/lib/hw/

[Miscellaneous Android Development] HridayHS:
May I know which issue will be resolved by gralloc.mt589.so ?

The device was getting unstable after some time. It seems as if it was a memleak. This gralloc lib is from E3 KitKat rom.

[Miscellaneous Android Development] EnerJon:
Yes, there was a memleak issue in this cm11 rom when we ported it using stock kitkat kernel to Elife E3 clone , and the issue was fixed by replacing the same file... Glad to see you back on this project (y)

One more issue i would like to mention is random reboots, after a lot of digging i found that you disabled "CONFIG_MTK_AEE_POWERKEY_HANG_DETECT" in your kernel source which is by default enable in mt6589 stock kernels and it is causing those random reboots for us... Unfortunately, those who don't have their device kernel sources can't disable it in their stock kitkat kernels, and such devices are stuck on mtk roms... The whole mt6589 community having stock kitkat kernels will be thankful to you if you can implement powerkey_hang_detect in your CM11 rom... Thankyou :)
[Miscellaneous Android Development] chrmhoffmann:
Yeah, not sure how this hang detection works. There must be something missing in user space that makes this work. Where is the project on xda that also found this gralloc problem?

Chris
[Miscellaneous Android Development] EnerJon:

If possible I will try to test with someone who owns a mt6589 and report back. ( Lot of people have moved to newer things and hence no one seems to have tried it )
[Miscellaneous Android Development] kannanrs:
Hey Guys,

I still own a C4, can i be of any help???
[Miscellaneous Android Development] zxczxcdani:
I'm still up for some testing.
[Miscellaneous Android Development] I.nfraR.ed:
I can confirm those 2 issues with my kernel and AOSP source for my device - Lenovo A820.

Initially, I had a huge mem leak with "original" gralloc lib. So hyperion70 gave me an idea to replace that file. I took it from bq Aquaris 5 stock KK rom and it worked.

The second issue was about AEE_HANG DETECT. It was a problem if the ROM does not have this functionality, but the kernel has it enabled (it is the case with all default 6589 kernels).

Since CyanogenMod does not have it (as opposed to leaked MT6589 AOSP source), it is probably causing this problem.

The other case when kernel has it disabled and ROM enabled was fine. So IMO it is better to disable this in the kernel config and I even removed that function completely from the source.

It was leading to random reboots, as mentioned in this thread.

Btw, this is how I fixed the random reboot issue on the CM11 port for A820 someone else did - disabled the hang detect in kernel.

I still can't boot the compiled CM11. There must be something I'm missing.

I didn't know you have the same issue, otherwise would have reported the fix much earlier.

PS: Actually used the gralloc from the kernel source on github: https://github.com/bq/aquaris-5/tree/aquaris-5/mediatek/platform/mt6589/hardware/gpu/user
[Miscellaneous Android Development] bhargav.k:
bro there is rom 4.4.4 port for canvas 4 working fine except cam it might help you pls get us a stable rom we want to taste kitkat
[Miscellaneous Android Development] I.nfraR.ed:
There are plenty of ported KK roms for A820 already in 4pda forums.

However, this is not the correct thread for that. All I wanted was to give a heads up to the OP, since he did a great job with CM11 for MTK6589.

Chinese people use the fixed kernel with the patch I did back in April and all of them report that the reboot issue is gone.
[Miscellaneous Android Development] andreya108:
Guys,

thanks for your work!

We've ported this CM11 build to Lenovo P780, but there are three problems (at least).

1) accidental reboots

2) cpu does not scales frequency down (always at 1.2GHz, though switches cores off and shows 0% cpu load when idle)

3) no deep sleep when gps is enabled

Do you experience such problems on Wiko? Any ideas how to fix?

Thanks!
[Miscellaneous Android Development] I.nfraR.ed:
Not sure about Wiko, but all these issues are present on other devices with ported ROM.

Perhaps the OP has newer build, but currently I still can't boot mine compiled from source.

The first issue is due to the power key hang detect function in kernel. If you recompile the kernel with this option disabled, then the issue is gone.

So, ask your developers to recompile the kernel.

Don't know about other two, haven't played with CM much, since I can't boot it atm and I don't like ports.

One option would be to compare both kernel sources and see if there is some significant difference in platform config.

Perhaps I can add P780 in my kernel, as I did with A830, but I need you to point me out a good config/custom folders for your device, which are proved to work.

PS: I see you're the developer of P780 kernel. Maybe you can add your config and custom folders to my kernel and compile it, then see if there's a difference.
[Miscellaneous Android Development] andreya108:
Yes, I've recompiled kernel and reboots are gone... (seems that i'm the only kernel developer for p780)

But the issue with fixed cpufreq is very strange. It's only under CM11. My kernel works almost perfectly with all other roms.
[Miscellaneous Android Development] I.nfraR.ed:
Yes.

As far as I know it is the same on A820 and probably other ports. Don't know about Wiko though.

Most of the people who once worked on MT6589 already moved to other devices.
[Miscellaneous Android Development] zxczxcdani:
Hey, did you guys try the galloc? Did it solve the memleak?
[Miscellaneous Android Development] chrmhoffmann:

Hi chrmhoffmann.

A big big thank from France for your amazing help to keep wiko users up to date the last android version (a lack of great number of manufacturer).

May i suggest you to add the following requirements for installing your rom in the first post:

Because a lot of people have a "7 error code" while installing the zip. And if you are

not flashing your rom very often (just like me), it is a good reminder to have all the step described in the first post.

[Miscellaneous Android Development] Dr-Shadow:
[MENTION=5238428]superdragonpt[/MENTION] is true, porting IS NOT THE WAY to go for future releases (with imgsensor and else - radio wifi are CORE FEATURES which are common to all mt6589 devices - imgsensors (for example) are device specific).
[Miscellaneous Android Development] waijeff:
Transplantation can offer tutorials on XDA it?
[Miscellaneous Android Development] Diego910:
Porting is the only way to do it for 90% of us without GPL
[Miscellaneous Android Development] superdragonpt:
Hi

I was actually trying to help.

Your answer is the perfect example of the lack of "know how".

That's why neither you nor the others understood what I said.

If you don't understand how this things works, and mainly what is the REQUIREMENTS to run KitKat, please use the search or Google it.

The requests on this thread, not only are off-topic, but they also don't make any sense.

XdA is indeed an place to learn, so here's your today's lesson ;).

To recap:

If you don't own your own kernel source, its the end of the road for you :/

If you device isn't GPL friendly, and doesn't have an complete and buildable kernel source, you just CANT port this.

You need your device kernel source, to compile an new recovery with SELinux <-- KitKat requires that.

You also need your device kernel source to patch it with the necessary commits to run KitKat.

Hope I was clear enough! :)

Regards ;)
[Miscellaneous Android Development] Dr-Shadow:
Request kernel source and explain why you need those !! I got kernel source updated from Acer and probably Wiko. What are you expecting if you don't ask correctly to your manufacturer ? You have to explain why it would be +++++ for them.
[Miscellaneous Android Development] Diego910:
Lol I've been requesting GPL for a month and I still doing it.

And yeah okey, I thought the other user booted ported cm11. Cm10.2 booted and some said so it wouldn't so I thought maybe he booted cm11 also
[Miscellaneous Android Development] superdragonpt:
If its only you requesting it, they probably won't do it.

Try to join an group of owners, and start spamming your OEM for the sources

not only its their obligation, to release the kernel source, but also like Dr-Shadow said, tell them how Much they have to gain by doing that :)

Regards and good luck,
[Miscellaneous Android Development] giaur:
I requested kernel sources from Mediatek and Lenovo, there is even petition to sign. Unfortunatelly, they conastantly blow off any requests, so it seems to be waste of time. They don't see any reason why they should share sources and they are not going to do this, at least for my device (Lenovo A820).

Isn't this possible to decompile/reverse engineer/recreate sources somehow? This is the only way - if it is not possible, we are lost.
[Miscellaneous Android Development] Diego910:
Thanks for your tips. They said to be preparing a platform for gpls, and last time they didn't have GPL available neither. I will give them some days and then start with that [emoji106]

Pd: sorry now I stop the ot
[Miscellaneous Android Development] Dr-Shadow:
Report all no-GPL compliant stuff at GPL violations (there is a mailing list)

First, you have to contact manufacturer of course ;)
[Miscellaneous Android Development] wasd-:
Some email template? :D
[Miscellaneous Android Development] giaur:
Is this the place where I can report that china people from mediatek constantly violate GPL license? But even if I report this, nobody can impact mediatek, so again it seems to be waste of time.
[Miscellaneous Android Development] Dr-Shadow:
First contact china manufacturer, get a reply and then contact gpl-violations. They have some ways to help you.
[Miscellaneous Android Development] giaur:
I wish it could be so easy, many people already tried but still we don't have sources.
[Miscellaneous Android Development] Dr-Shadow:
I see no mail at gpl violations about mediatek kernel source. (It's a public mailing list guys...)

Only stupid petitions with "force mediatek to release source code" (which is a totaly wrong request) or "let's spam ZTE to release kernel source" <- this is a good idea but it would be better to get a conversation that goes in both directions.

PS : Let's stop talking about that here...

[Miscellaneous Android Development] stelios97:
That's because mt6589 phones doesn't only share the same cpu but they also share same Gpu, network modem, bluetooth, wifi, gps and etc so the drivers are the same. Correct me if am wrong. We don't see such question on other phones threads because they may only share same cpu.
[Miscellaneous Android Development] Diego910:
Same CPU and GPU it's very common in all phones. But there are lot of things that aren't in the specification paper, about Bluetooth modem and that... I dont think so, if you port roms some of that things don't work so it depends on the phone.

For example mine has a strange partitions.

Also if you compare projecconfig.mk you can see a lot of differences with all devices, I don't really know if that file is relevant but it looks like, maybe someone knows more about that file
