im using s232 rom rooted and 3.2.0 twrp

is there any one got the same thing here?

please help.
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] PraneethMv:
Try using twrp 3.1.1 instead. Also, before flashing, did you perform full wipe? Dalvik/ART Cache, Cache, and data(excluding internal storage).?
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] wauwerz:
Thanks for replay.

I'll try with the two 3.1.1

I use twrp 3.2.0 that upload at the first page

I already full wipe before I install it
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] PraneethMv:

e: unknown command [log]

e: unknown command [log]

and i have no problem atall. but when i try to install dolby atmos with several version, i got mey system ui has stopped. either with TWRP or by magisk.

did any one here successfully instal dolby atmos in this RR rom?

sorry for my bad english
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] PraneethMv:
Yes. You can still use the ROM with that error. It will work fine. And for that Dolby thing, dont flash the one in magisk it will give system Ui FC, because its made for ARM devices whereas ours is ARM64.

Search this thread for Dolby Atmos, one member has given a link to a working Dolby Atmos. :) After installing it don't forget to wipe Dalvik Cache. Im currently on AM3D Sound Mod + Dolby Atmos. Its working amazingly! :)

Hit thanks if I've helped. :) :highfive:
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] wauwerz:
wow thats awsome.........................

okay then ill start to search that...

thanks man..................

its really help
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] PraneethMv:
Here to help anytime... :)

Well, for installing Dolby there is no special methods to do, just flash.

But if you also want to install AM3D( Search for that in other forums its a mod by ahrion), then its a bit of a workaround. If you want to know how PM me I'll tell you(dont want to clog the thread here).

Zero Addition kernel is integrated into the rom by default. No need to flash it separately. I think dev might fix the bug in next build, as he had mentioned in his other rom AOSPEX that he will fix the bug of YouTube videos in the next build. Hope mohancm also fixes for this rom too.... :)

No same problem here...
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] PraneethMv:
Can you tell me whats happening with Dolby and poweramp? Because as far as i know... Correct Dolby should work with any given music player. I guess poweramp has an in-built equalizer, which might interfere with Dolby. If it is so, try disabling the poweramp equalizer. :)

---------- Post added at 04:08 PM ---------- Previous post was at 04:04 PM ----------

In our RR, the pre-installed Magisk is v12, which does not have SafetyNet bypass. (It was removed in this version due to some issues). If you want to try SafetyNet again, flash Magisk V13 Beta from the official thread. Be aware that it is a Beta build,so it might have some bugs.

[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] PraneethMv:
Did you uninstall the previous dolby which you had? Because you cant run two audio mods at the same time, neither of them will work. What i suggest is, do a clean install again, wipe and flash the rr rom again(taking backup of your apps and files ofcourse). After doing that, flash the dolby which i mentioned earlier(pg 91). Wipe Dalvik/Cache, reboot, and try it now. It should work.
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] DarKrypton:
Hey there. I wanna uninstall dolby. Which i flashed from a file. But it's not working i guess. So without flashing full ROM again. Is it possible to remove it? Please let me know. I need to flash another dolby, which you provided on page 91. Thanks.
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] mohancm:
Thanks for informing.

I am busy with exams, so not active on XDA.

I am thinking to stay on my codes, if everything goes well. Else, I will adapt his source.

I am testing those , let's see ;)

Thanks for [MENTION=7739639]Zormax[/MENTION] for making it open source :)
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] PraneethMv:
From which forum/thread did you install that previous dolby? You can go check that forum if it has an uninstaller. Else, the only way is to clean install the rom again.
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] DarKrypton:
Umm, it's was here on this thread. In previous pages. But no uninstaller. :l There is one uninstaller in this thread. Next to your post(on page 91). Should i try that? Take a look. Name : dax_uninstall_v2.2
[Lenovo Vibe K4 Note ROMs, Kernels, Recoveries, & O] PraneethMv:
dax_uninstall is for Dolby Atmos made by ahrion, if you flashed the dolby by ahrion, then use that uninstaller. You can also try using that uninstaller, but if yours is not from ahrion, then it might return some errors. Try that, if it doesn't work, then only thing you can do is clean install the rom again(recommended)... :)

I don't think there is a way to uninstall root. You can try Uninstall option in Magisk(i have never tried it though). Or you can flash AOSP Extended Rom by mohancm which is very similar to this rom. :)

All Roms are good and with some minor bugs like Camera 8 MP, Stock Camcorder Buggy but third party Camu app records video, Buugy Data Recording, No Volte, No NFC and some minor glitches in Sensors.

For Call, SMS, Internet, Multimedia, Audio, Light to Medium Gaming it can be used as daily driver and very stable and fast.

Camera is still not fixed yet completely developer is working hard on buggs. RROS 5.8 is good as developer has released more update and bug fix.

For me these are better choice when you are not a camera freak and contain with some limitation which seems not that important for me at least.

Go and try.

Good Luck.
