[Android Software Development] pix106:
this problem has already been reported, in a russian screenshot, so we were unable to read, nor to use a translator on an image:)... it took a while to understand what it was about !

Tried cm12.1,performance is extremely improved.Only bug I found is the video recording,gives cant connect to camera error after a second.On antutu scores 26k,stock rom is 25k,although it feels much faster than the score shows :D

Forgot to mention,fm radio is missing.Can you add it in future updates?

yes , just checked video recording not working. Will try to fix. (I never used it:D) I thought it'll work since its working slimLP.:)

If you are using video camera use this apps, video rec working with this two apps.

Camu :- https://play.google.com/store/apps/details?id=com.sumoing.camu&hl=en

Footej :- https://play.google.com/store/apps/details?id=com.footej.camera&hl=en
[Android Software Development] pix106:
Battery profile default value is "performance", it helps :)
[Android Software Development] thp@1997:
Yeah, updated device tree before compiling set to performance to avoid any lags.
[Android Software Development] MaRtYy01:
Great :D

Im using camu on my lenovo a6000's CM14 since video recording doesnt work there too,it seems a little laggy compared to stock video recording apps,probably because there two most likely use software video recording.Not a problem anyway,I barely never use camera.

Also,might try crossporting again,cm12.1 seems like a far better base than the stock rom.If you look at that page:

http://cmrom.blogspot.bg/ I can crossport like 15 roms(without counting the 5.0.x based ones and cm12.1 which we already have),so that would be fun XD [I will start with cmNos,since it looks so badass.If everything goes fine I will continue with flyme os and gotta port em all(it will probably take me some weeks/months since school)].

Thanks, I appreciate that you didn't / wouldn't provide this for a7-20F ? .

However, I was asking as 'pix' in nomenclature made me suspicious, and because I hadn't thought how I might be able to check this.

I just now got a little more imaginative and followed link in your OP here to your TWRP thread (nice work!), and downloaded your 3.0.2-0 TWRP to compare file details, and my suspicions are now confirmed. File size and checksum are identical.

Tab 2 a7-20f thread at 4PDA https://4pda.ru/forum/index.php?showtopic=711492 lists older Russian madeTWRPs for this device, but three years ago your 3.0.2-0 TWRP was posted, and is linked as latest for a7-20F in the cap ('hat', under 'Helpful Information'), so I guess scores of Russians have been using it largely successfully with this model. I had no inkling till now that it was actually for a different device.

Anyway, this suspicion made me think there could be a connection between TWRP and bootloop problem when Magisk modified boot.img is flashed over your CM 12.1 (patched for A7-20F). Still suspect TWRP may be the problem, so I'll try using proper a7-20f older Russian TWRP soon. Based on success with your 3.0.2, I might try with your 3.3.1 on a7-20f - when I'm feeling especially reckless ? . Regards, PW

Question on flashing kernel to TAB2

Hello there. Thanks to the developer for all the efforts done already on this tablet. I own this device and i've a question.

I built a custom kernel with usb wireless support. Unfortunately when i upload the kernel to the tab 2 using fastboot, after lenovo logo the tablet goes black, but it is running because i can adb shell to it. I have restored the original boot.img and tried different toolchains but i end up getting the same results. Do i am missing something related to video settings? any help is appreciated and thanks in advance.
[Android Software Development] pix106:
I had the same issue when i tried building kernel from lenovo source some years ago when i tried, it seemed to be working but with no graphics at all.

I suppose either there is something more to do to enable graphics, either source is incomplete... or both.

That's why this rom uses prebuilt stock kernel.
[Android Software Development] kremvax:
many thanks for the quick response!

Can I use this ROM to do that?
[Android Software Development] pix106:
You can't it's for a7-10f

I don't support other devices, even if there's a package on 4pda which is supposed to make it work on a7-20f.

If you try, you're on your own, don't ask anything more here :)
[Android Software Development] Sonicboom72:

[Android Software Development] pndwal:
Yes, with 4PDA patch. SuperSU for root works fine, but I haven't managed to replace it with Magisk.

Patching rom boot.img with magiskmanager, and flashing the patched boot image with twrp works.

Have a look at magisk thread about it if it's not clear
[Android Software Development] pndwal:
Thanks again for that, but you already gave me that advice, and I understand there is no problem on supported Tab 2 a7-10f. But on Tab 2a7-20f w/ 4PDA patch, no dice. Probably due to the way patch alters boot.img, or using your TWRP on a7-20f (different partition tables etc?).

Dear pix106 your link is not working yet. But I found the firmware in your profile, I don’t know the latest version or not, but I’m impressed. Standing up applause! I will describe first impressions, what improvements I noticed and what small bugs.

Firstly, YouTube works in 1080/60 without stuttering and lags. Direct stream now works! Previously, when downloading files, the tablet froze, now it does not. In general, the system has less lags and freezes. Your firmware is better than stock! I always wanted to use it , but earlier I could not because of YouTube, because of lags, but now this is the best option for our tablet, the sound in your firmware is better than on the drain and performance. One moment in the new firmware, when I installed murglar and logged in to deezer, then The stock webview did not work, I had to download the webview from the play market, only then the deezer authorization interface in murglar started working. One more thing, during long operations, the tablet still lags a little. Transferring applications to sd is also impossible. But in general, you did a great job, this is the best firmware, thanks to pix106.Your link is still not working, maybe an even more recent firmware version is provided in it, and I downloaded the one from 29 Aug 2020
[Android Software Development] pix106:
Thanks for your feedback !

Link should be fixed now, this was my mistake.

The build you downloaded is the latest.

Hi.

Testing your build from august:

- problem with some streaming content

- after few reboots I get bootloop

Otherwise:

- few lags here and there, not disturbing

- everything else seems to be working

- youtube (Vanced) easily 1080p :good:

- missing FM radio
[Android Software Development] pix106:
Thanks for your feedback.

I had not made it clear before (my bad) but testing the rom is expected to be :

a clean install with data wipe : no upgrade from previous builds

without any external change except gapps (i use pico opengapps) and magisk (magisk only, no extra module).

Any sound mod, magic system optimizer, xposed, magisk modules are excluded.

I must be able to trigger any issue on my device to trace it : so please give precise informations

Providing logs (logcat) is expected when reporting issues.

please tell which "streaming content", exactly, you had problems with, and provide logs if you can.

I had none here, did you install any crapware such as sound mods, xposed... ?

standard Youtube app should be working fine with this build.

For now i could not make it work, i'll probably try again some day.
[Android Software Development] franciz666777:
I made clean install (wiped data, system, cache, dalvik).

I did not install any crapware mods.... I use built in SU.

Youtube Vanced gets me 1080 video, Youtube app from Playstore gives me only 720.

I grabed log for streaming content (with Cat Log, I hope it is OK?).

First is for Xplor TV app - certain video stream are shown OK, for some I get "internal error" and no video is played.

Second is for Chrome browser - video does not play. Try for example playing videos from https://siol.net/videoarhiv/

Both works OK in stock rom. I think it might be h264 codec related..

I cross my fingers for FM...
[Android Software Development] pix106:
Ok I'll have a look at your logs when I can.

Video recording failure is also most ptobably related to codecs. If someone is comfortable with this, he/she can contact me.

Imo, magisk should be used instead of embedded su, which is quite outdated.

What's the purpose of playing a 1080 video on a screen that has a lower resolution than 720 ? :)
[Android Software Development] franciz666777:
For playing on tablet you are right, for chromecasting to TV 1080 is very handy.

BTW chromecasting works perfectly :good:

the built-in player did not see the sd card and this is how I solved the question, formatted the sd card in the tablet itself and after rebooting the tablet, the built-in player saw all the files.

Thank you for the fact that many years after the release of the tablet, you made a new excellent firmware on it, it is very rare for someone to take up the firmware on such an old device, your firmware is better for stock
[Android Software Development] MaRtYy01:
This is more of a long term review of the 20201025 build as I have been using it for the past weeks. The build works better than I expected, video playback works without issues and this is the most important update compared to the cm12 builds from years ago.

There might have been some minor issues that I haven't noticed but everything important works and I haven't experienced unusual behaviour such as soft reboots and hard freezes(impressive stability).

Keep in mind that I haven't been using the tablet too much as it's slow. I guess it's too old and weak at point but it's still nice that it is usable, considering that it's a 5(nearly 6) year old 75 euro device. Infact it works better than I anticipated.

I remember from testing all lollipop roms on one htc one x years ago that cyanogenmod based lollipop roms run slow in general on low end devices. SlimLP was the fastest rom back then, as it's based on aosp it's probably a better choice to build for this device(if that is possible, I'm not a developer so I'm not exacly aware what is needed to build a rom).

Also a tip for the [MENTION=3064479]pix106[/MENTION] , you should probably make the new builds of the rom public so more people can access them. I have used countless public roms for various devices that claimed to be in beta/stable state but had major issues, this rom on the other hand is stable for real. It is definitely ready for public release :)
[Android Software Development] pix106:
Thanks for this review !

Builds are already public since... yesterday :)

You can update to the latest one.

SlimLP was, iinm, the base for OrionLP that thp1997 built years ago with previous device source, which he modified... but deleted.

I had built pure aosp too some years ago, but it was not stable, i suppose the same changes were needed.

I'd like to add FmRadio to CM build before, maybe, trying to build some other rom.

I actually already built ResurrectionRemix recently, with new devide source, but it was not working as good as CM.

Which governer is used in the latest rom? If it is performance, is there an additional boot image with hotplug governer Working like you previously posted?
[Android Software Development] pix106:
The new 2020 build uses CM power profiles, i already included the fix that prevents max cpu frequency to be limited after sleep.

You can check the source if you want to look more precisely.

EDIT: the included workaround is actually not working as it should.

New workaround in next build.

performance enhancement

replace hotplug with userspace governor (powersave and balanced power profiles)

after tablet wakes from sleep, cpu max frequency is 1040MHz.

There is no unlock, just flash TWRP with SP FlashTool, boot to recevery and install rom/gapps/magisk/...
