Just unplugging the battery didn't work for me. After a week of "brick and unplug", today I can flash the tab.

Don"t know, why it works, but I think, the battery is fully off. I make a try after dinner, and it works!:D Thanks [MENTION=4606952]Diabblo[/MENTION]
[Android Software Development] mayank22:
Its not about the max frequency. Its the only frequency that the cpu keeps running on. No other frequency is used. Whether it be 1040 or 1300Mhz. Only hot plug governor works fine, but its a little buggy.
[Android Software Development] pix106:
I think i'll actualy just remove cm power profiles, as i've never realy been convinced it's usefull to force performance governor, and as kernel is not behaving fine with it.
[Android Software Development] mayank22:
Yea they are somewhat useless. But that means power saver mode will me gone too?? For now i have changed the up_threshold value of hotplug governor from 85 to 65 and i am getting a good balance between performance and battery life.
[Android Software Development] Jarvis448:
Need help asap...after i tried to install twrp,my tab got hard bricked..it's not turning on anymore..i've applied every possible method to flash the stock rom..but sp flash tool can't detect my tab..its showing brom error 2005..i think my preloader is dead..plz help me
[Android Software Development] pix106:
If you tried to install twrp build for this model, imho you can't have broken your preloader.

Try to unplug the battery, it will certainly work again afterwards.

And please post in a general thread, not in a rom thread as your problem has nothing to do with this rom.
[Android Software Development] MaRtYy01:
Unplug the battery and first flash preloader,then the rest of the rom to unbrick the tablet.I know you have to open the tablet to unplug it,but just see how to do it in youtube,use a dull knife,I dont think everybody has one of the special tools for opening phones and tablets,it worked for me like that.
[Android Software Development] enzo24754:
I didn't even need a tool, i was able to open it with my thumb
[Android Software Development] pix106:
Thanks guys :)

Finally i did not remove cm power profiles :)

Instead, i tuned the power profiles, so it seems to have a normal behaviour (= cpu_min and cpu_max frequencies are kept after resuming from sleep).

hotplug governor for "Powersave" and "Balanced" profiles

performance governor on all 4 cores with cpu_min=cpu_max=1300MHz

These modified profiles will be added on next build.

Thus, "Balanced" power profile will now be set on boot, as it gives good performance ; hopefully it will save some battery life without noticing it.

Need testers : in you want to test, flash boot_hotplug_4perf_1300.img from Downloads tab on boot partition using TWRP, BUT "Performance" profile will still be set on boot as it is not only set in boot.img.
[Android Software Development] mayank22:
I have tested it and it works fantastic:good:

Balanced profile with default hotplug works perfectly fine.

Any update regarding hw decoding and fm radio?
[Android Software Development] pix106:
Thanks for your encouraging report :)

I'd like to have some more reports about this governor changes before including them in the mainline.

FM Radio :

thp@1997 was working on it last time i heard about him some weeks ago.

To be honest i did not really try anything for FM yet.

HWC :

i tried a lot of things, build flags, sources, blobs... but nothing worked for now.

I may be missing something obvious, as it's my first rom building project. Any experienced opinion would be useful :)

Building other roms :

mainly to try to get some other logs for the HWC problem... and because it's frustrating to spend hours trying things that don't work, so doing something new is good !

CM 12.0, Omni 5, AOSP 5.1, CM13 (it did only partially boot when using CM12.1 bootimage, there seems to be something different about bootimage in CM13/MM).

I have made them boot, but did not polish them in any way. I would like to fix and understand HWC problem before doing anything more for any of these versions, if any is to be released.

Building a kernel :

my last activities about improving this rom are about building a kernel using lenovo's source and config.

I get the built kernel to boot the rom, android seems to be booting fine... but without display. Nothing but black screen after power on logo.

In logcat i see resolution is wrong (1280x800), and i can't get to make it right (1024x600).

One more thing :) :

I have also tried replacing some blobs from stock rom with libraries built with CM source e.g ibion.so and some other ones.

It works fine for me, but it's not merged to the released builds for now, I may include these changes in the mainline later, after a testing build first.

I also used a source on github to build gralloc-extra.so. I may try to find some different source, as it may be related to HWC (am i right ?).

Any help/hint is welcome !

Dear PIX,

THANK YOU :) this rom makes the tablet usable.

[Android Software Development] mln91:
Have you tried to use prebuilt kernel from 4.4 instead of the one from 5.0?

I ask because those guys Lenovo Tab 2 A7-30/H CyanogenMode 13 are using 3.4.xx kernel from 4.4 (probably because of buggy 3.10.xx kernel from 5.0, which has problems i.e. with touchscreen) and the ROM works perfectly.
[Android Software Development] pix106:
i did, but i may have missed something as it did not boot at all (no adb, nothing).

I tried replacing LP kernel image with the one from KK. Maybe there's something more to do.
[Android Software Development] MaRtYy01:
They are using it because 3.10.54+ mtk kernel cant boot something newer than 5.1.1 yet.3.4.67 can,and this rom is ported from mt6582,their mt83xx chipset is 100% identical to mt6582 so they dont have to crossport.
[Android Software Development] fazloon88:
Advice needed

Thanks for the post.

I would like to ask that I have Lenovo A7-20f. Is this ROM will support my tab if I flashed it ? Bcz it's has the same chip set as A7-10.

Please your advice will be very helpful.

Thanks in advance.
[Android Software Development] pix106:
Officially : no, this ROM (and others) is for A7-10F MT8127 only.

Unofficially : yes but you will lose rear camera. Do not ask anything if anything goes wrong :)
[Android Software Development] JurandZeSpychowa:
Hi, I have a problem with my tablet.

I use it to listen to Spotify music in my car, so I need offline cached music.

The problem is - Spotify doesnt see external sd, and internal storage is almost full.

I tried older versions of Spotify, different sd, deleting cache and dalvik cache and even flashing system again - nothing.

Can somebody find a workaround?

There isnt option for ext sd, it just shows internal storage as ext sd.

On stock lenovo rom it worked just fine.
[Android Software Development] mln91:
How about CM11? This ROM is of course fine, but CPU freq-scaling problems and wi-fi related things (poor signal quality, lags when downloading large files) are annoying.

Those things are not present on 4.4 so maybe CM11 is the way to go?
[Android Software Development] pix106:
Wi-fi signal problems ? No one mentioned this earlier.

KitKat is outdated, and honestly so is Lollipop if we stop getting security updates (it's not been merged in CM12.1 this month, maybe November patch is the last one we get)

I've been trying to use KitKat 3.4.67 kernel ant blobs, but I did not get the ROM to boot for now. Init scripts problems imho, that's the part I don't like :)
[Android Software Development] mln91:
Wi-Fi signal seems to be weaker than on 4.4, I think it concerns stock 5.0 too. It's not critical though.

Lag problem is known, right? I've read people complaining about the lags on 4pda.ru. I tried to change IO scheduler to noop but it doesn't seem to help. Is it another 3.10.x kernel bug?

And sure, CM11 is outdated, but lags happening when downloading large files / watching something on YT are very annoying. :( And it seems that CM11 is some kind of workaround to this thing if we can't get CM12.1 working with 3.4.67 kernel.

After all, I think this ROM is great. ;)
[Android Software Development] mayank22:
Yea there r wifi signal drop issues and panel in quick settings is buggy too.

Btw flash the test boot.img from download tab and change the profile to balanced, performance will get a huge boost!
[Android Software Development] pix106:
I tried using wifi blobs from stock ROM, I noticed better connection time, but I don't know if it could improve signal.

Moreover, WPS and connection sharing were broken when using these blobs in October when we worked on it with thp@1997.

I can try doing a test build later during the holidays with these blobs and see what you guys feel about it.

Using the test boot.img, performance is good for some time with balanced profile, but sometimes become a little laggy after some time.

After a few dozens downloads of this test boot.img, only 1 person reported about it... Guys are you shy ? :)
[Android Software Development] mln91:
Such test build with stock wifi blobs would be great, it would allow to check if the lag thing is caused by Wi-Fi drivers.

I haven't tried the test build.img because I'm happy with my custom CM performance profiles. However, the lag thing happens even if CPU is set to 4x1.3GHz so I don't think it's related.
[Android Software Development] mayank22:
I think including a little zram will help in getting stable performance over long time.
[Android Software Development] pix106:
... If we could build a working kernel from source...

:)
[Android Software Development] mayank22:
But that can be done by init.d scripts too afaik? I will try myself and report :)

[Android Software Development] pix106:
There was no update since November 2016, you may have read it wrong.

There are no more updates from CyanogenMod, there was no security patch since the last build, so there will only be an update when there is something fixed from the not working list.

I need help, I keep trying things on my free time, but I don't know how to fix the video streaming problem, nor how to make the kernel I build boot with graphics, nor how to make cm13 boot image boot (but it kinda boots with cm12.1 boot image).

Hi, I would like to participate and build ROM for this tab. I have the tab already. Let me know the procedure. I searched for device porting and rom porting but I couldn't understand. It will be helpful if you can help me to port AOSP rom for this tab in brief procedure.
[Android Software Development] pix106:
This ROM is not a "port", it is fully built from android source, with a homemade device tree and some additional sources for some additional features (internet sharing, headset icon...).

You need to set up an android build environment, and a local manifest that uses the sources from first post.

I have already managed to build AOSP this way, but did not go further with it, as I think YouTube live and HWC problems have to be fixed first.
[Android Software Development] thp@1997:
As per my research I recently tried Mtk proprietary codes to get it working but it seems that codes are too old. I don't have access to new mediatek codes that's why I'm stopped for now.

Look on TWRP thread, you'll find links to SP Flash Tool howto.

As your problem has nothing to do with this particular ROM (or twrp recovery), but is more a general flashing problem, please use a general thread to ask for help, this is offtopic here.

Just boot partition, or nothing at all as you can flash CM12.1 over to restore "normal" boot image.

Yesterday my battery was 72% and after 20 minutes of Youtube has dropped to 68%. Is it normal? My LG L90 doesn't consume battery like the P9 Lite.
[Huawei P9 Lite Questions & Answers] lzimbrea:
This isn't an issue.

Check your power consumption level.

Remember that apps like Facebook, messenger are running in background.

Also lg L90 has a 540 x 960 resolution, and p9 lite have full HD display ( 1920x1080). Screen and CPU are the most power hungry pieces from your device.

Huawei have a battery optimization tweak for you.

You can find it in settings->advanced settings-> battery

Select your preferred power plan.

4% consumption for 20 minutes of video playback isn't a problem at all
