Android pie aosp bootloop on cubot j3

[nonyonah]

I have a cubot j3 with android Oreo go edition . I installed the latest aosp pie version from here but it seems that it's been on the android logo for a long time till I have a switch it off. I installed the 8.1 version and it booted but the Google certification is an issue. I really wanna try the pie rom, I don't know if it's cause of the RAM or something, help support it. It's an mtk 6580m device

What about the "being stuck on the android logo part" when I install aosp 9. How do I fix that?
Besides the Oreo rom is actually Oreo go with the original Google apps installed, I wanted the main one

[proganime1200]

post the the report log the only way to grab them is with the command I gave :

• from a computer : adb shell cat /proc/last_kmsg > log.txt
• inside TWRP, in terminal, cat /proc/last_kmsg > /sdcard/log.txt (maybe sdcard should be changed to another location)

What does it do?

Still not working

You need to do a proper factory reset when switching ROM, with stock recovery if needed.
The logs shows that you didn't properly factory reset (I'm not totally sure it's the issue though, but logs are noisy because of it anyway)

[phhusson]

Also, you cut the log when adb stopped, you should have re-run adb after it to another logfile to have both logs.

[nonyonah]

So how do I properly factory reset? I followed all the steps and besides I managed to boot up descendant os and your rom too but that long boot up time is always the issue there

[nonyonah]

I'll try to run another log when I have the time, thanks for your ROMs though. It gives hope to many unsupported devices like mine

[phhusson]

Wait, issue is just boot time?

[nonyonah]

Yes! It takes up to at least 10 mins before booting up

[nonyonah]

Any fix for that?

[nonyonah]

Any fix?

I have an alcatel 1x ,This also takes more than 10 -15 mins to boot up..Also sometimes it never boots up.
Looking through the logs I think the mtk audio hal service is extending the boot time.

[nonyonah]

So how do you fix it?

[Pey-crypto]

reboot to the custom recovery and enable adb.....
then pull the build prop file from the system folder and add the this line.
ro.audio.ignore_effects=true
fixes the long boot time..
#576
saw it here

[Pey-crypto]

I read the log file and looks like mtk audio hal service is not the problem.... run adb logcat after the device reports it has booted in the log.Post that log

Ok
