arter97 Pie Software Collection for the Mi Pad 4

not sure about this, try flashing the old kernel and go back again to miui with full wipe and reflash miui rom

I already flashed stock boot image, it is stock kernel, isn't it ? I also could check the kernel version (uname), it's not arter's kernel anymore.

I have no MIUI but xiaomi.eu rom, is that enough ? How to download a China stock rom ?

I also tried to restore "modem" from the TWRP backup I took before flashing anything on my tablet... Nothing better.

If only I had understood that this package would change anyething else than boot and vendor images I had a backup for...

Hi again, I was looking at the commits history and I found this, which made me ask myself another question, I'm not an expert in the kernel world, nor in the file systems, but, there really is a measurable difference in energy consumption between F2FS and EXT4? I mean, I use your kernels since the Galaxy S6 times (S6, 1+3T, 1+5, 1+5T, and now here), and whenever I had the opportunity I used F2FS, and honestly I can't remember a decrease in the autonomy of the device when I changed the file system (But I don't rule out that this happened at some point).

I/O related stuffs are barely related to power. Even if it is, it'll be extremely small and impossible to measure.

I'm not sure why you got curious of power consumption by looking at that commit.

@arter97
Any clue about the wifi problem of the last pages ?
To sum it up : wifi can't connect anymore after reverting to stock vendor and kernel, even after a full stock flash with miflash.
I suppose /persist has been modified
Thanks for your help.

I cannot help you unless you provide me logs(kernel and logcat), and still then, I may not be able to.

I posted a logcat a few posts ago, from a miui xiaomi.eu ROM with my data backup restored.

What would be best condition for a clean logcat and dmesg : any rom after a full wipe ?

Preferably stock. dmesg is also required.

I'm aware that the latest update broke PA.

I will prepare for an update soon.

Can you enable cifs support in the kernel.

 

[stunned]

Do you ship firmware files with your rom or what firmware is supported? I believe these contain closed source security fixes from Qualcomm etc. so they are somewhat important https://xiaomifirmwareupdater.com/#weekly

With Mido (redmi Note 4) firmware files needed update after Android version bumb to work. When/if official Pie is released that might cause some problems with people using Pie before moving to custom roms.

Thanks for the update. Most of everything is working without problem. However, minimum brightness is too bright. Around 0-10% brightness is the same, not change.

Preferably stock. dmesg is also required.

I got wifi working back.

I had a backup of /persist/wlan_bt/ and /persist/wlan_mac.bin.
I restored it, but WiFi only worked on omnirom, which I was using before installing arter's collection. Maybe omnirom had something to do with wifi failure, i suppose i did the backup after i flashed omnirom, but don't remember exactly.

To make WiFi work again on stock and havoc (and probably other roms), after restoring /persist/wlan_bt I had to copy /persist/wlan_bt/wlan.mac to /persist/wlan_mac.bin.

I restored all files using adb and twrp.

That's what i did, i don't know if it is the best way to recover.

Edit : the best way to recover is to make a backup of persist partition before flashing anything, and keep it safe.

You can extract persist.img from Miui fastboot rom and flash it in fastboot (fastboot flash persist persist.img).

There was no persist.img in the fastboot stock rom i used.

After going back to stock boot + stock vendor + normal twrp + format /data (ext4), wifi does not work either.

With a fresh LOS 16, there is no network in list.

With xiaomi.eu rom + restored /data backup, it tries to connect to my home wifi, fails, tries, fails and so on : Logcat

I had wifi issues, followed the guide from the linked post below and it was resolved.
