somebody please kindly help me out on flashing this kernel on my oneplus 6t....the instructions are so complicated...i bricked my device 4 times...please help
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] return.of.octobot:
I don't know how much more straight forward the instructions could be, you can install the kernel via zip or boot image. If you're using the zip, you flash it via TWRP by selecting the install option and locating the kernel zip on your internal storage. If you're using the boot image, you install the kernel from your PC via adb/fastboot with with command

fastboot flash boot [NAME_OF_IMAGE].img

That's about all there is to it.
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] funnyquill:
I was able to format data to f2fs successfully

I flashed kernel successfully too

But the problem is when i boot to twrp

I can locate folders i mean there numbers instead of file names and neither I'm able to copy files from pc to device when i boot in twrp

Any help plz..?
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] Ellcid01:

[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] funnyquill:
You mean after doing all the stuff i have to factory reset from twrp right...?
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] Ellcid01:
Not factory,u need to do advanced format and format data, and digit yes
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] funnyquill:
Just one last question

Should i first format data to f2fs or should i flash the kernel n afterwards format data to f2fs..?

Plz help

[MENTION=4898097]arter97[/MENTION] I have a Poco F1 and a OnePlus 6.

I'm using a script on Poco F1 to remove thermal throttling it's a "gnfc.sh" I can give you the file.

For instance app like PUBG used to open in 25seconds on both earlier. Now after OOS 9.0.4 I've seen OnePlus 6 opening PUBG in 30+ seconds and also lagging alot more than that.

Then I flashed Oxygen OS on Poco F1 and similar to OnePlus 6 it slowed down too.

And "gnfc.sh" that I used to run through SManager app doesn't work on OxygenOS.

Is there any such script or thermal configs that you can introduce for our OP6 considering OnePlus slowing it on purpose and a 300$ phone with that script faster than our OP6 is just plain bad.

If you could help it'd be awesome.
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] q-ki:
Hi.

1)

The original kernel does not support usb2lan ( I asked the support)

I've looked at the other available kernels for the op6 and no one is listing this feature.

So it seems this is the only kernel for the op6 with usb2lan-support.

Has someone tested this and can confirm that it is working?

I want to buy this phone. But I am not going to if I cannot get usb2lan.

2)

What control-app is supported by this kernel?

And what governors are integrated ?

Thanks for your help.

Cheers...

So, can anyone take please tell me what the f2fs_optimize.zip is meant for? Let's say I choose to flash either the decrypted or encrypted f2fs files then proceed with the instructions and flash fstab afterwards. Is the 'optimize' files meant to be flashed afterwards or what? There's no info about that.

[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] dragos281993:
It happened to me after flashing the stock rom without removing the FP before. It was too late when I remembered I had to do that. Flashing the rom automatically changes the active partition so everything you see in gibberish looks like that because the partition was encrypted when you flashed the ROM.zip. I personally didn't try anything other than wiping the internal storage but you could just boot into twrp and sideload the ROM.zip. That's gonna switch the active partition back to what it previously was (A or B) and you might get your user data back.
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] mascian:
Thank you.

However, keep in mind that I've formatted everything (swype all and Format). Then I used "flashall.bat" to restore the phone as new, and finally I installed the various roms (twice stock and AOSP).

Do you think the same one had the fingerprint problem?

Hey arter97,

First of all, thanks for the great kernel, I have noticed much improved responsiveness and battery life over the stock kernel.

I have been using it, albeit with ext4 but only since I am too lazy to back up and restore all my data after formatting to f2fs.

After flashing this kernel through blu_spark TWRP, I flashed blu_spark TWRP again and after rebooting to recovery, it was unable to get past the boot logo of the recovery. So to flash magisk I had to fastboot boot TWRP.

Is there any solution to use TWRP without a PC?

If I remember correctly (been 8+years now) you used to do stuff for cyanogen mod, back then on few of devices I also owned.

In case of f2fs on data you won't have encryption, which is number one important feature on the phone (well unless you don't care loosing phone and someone using your data).

If you're comparing speed you usually compare encrypted fs (OOS) vs non ENCRYPTED one on f2fs, so this is not quite fair.
