I'm talking about the Kernel to go with that firmware. I'm already *on* that firmware, but I want to try the OP's kernel that this thread is about. :P

What is the "DRM" many posts on here mention it. Also for this rom what is the camera like I'm afraid to install any roms if it means the camera quality will be very poor.
[Sony Xperia XZ1 Compact ROMs, Kernels, Recoveries,] tonsofquestions:
DRM is "Digital Rights Management" - the same kind of thing that exists to protect movies, music, etc.

In this case, it's basically a special key that exists on a partition of your phone. (In the stock ROM) Sony checks it's existence before doing certain things - like taking photos or other advanced camera functionality - and if it's missing, won't let you use it. Sony also wipes the key when you unlock your bootloader, effectively making the camera useless (again, in the stock ROM).

Note that Sony is in the minority here - while many phone manufacturers won't let you unlock the bootloader at all, those that do don't typically disable core functionality like that, and it's a point of contention.

However, like many good modders, once we have an unlocked phone, we have access to all the software, and folks have made patches so that the camera can work again without the DRM keys. Hence the "DRM Fix" Kernel this thread is about.

This isn't a change to anything substantial - the camera should work the same as before, it's just bypassing the check. Note, though, that this thread is just for a kernel - it still uses the stock Sony ROM. Other ROMs exist, and might use different camera software, so your mileage may vary there.

But it's unlikely that the camera will be "poor", you might just not have access to all the same settings as in the stock ROM.

I hope that helps clear it up.

Totally grateful for his work, after running all the steps Android Pie works at 100%. A couple of details just with the idea of improving the post:

1. In the installation instructions, the correct line should be:

fastboot flash recovery name-of-twrp.img (flash twrp-recovery)

(twrp-3.2.3-0-lilac-pie-2)

2. To run WifiDisplay you must install Magisk and the module (by [MENTION=4688377]russel5[/MENTION]) available in https://xdaforums.com/showpost.php?p=78353750&postcount=21

and that would be it, again very grateful.

Hi Janjan,

after reading many good things about your work here, I would like to give your kernel a try.

My device: G8441, unlocked Bootloader, TWRP 3.2.3-0 (latest by modpunk), Android 9 (47.2.A.4.45 over flashtool, no reset), Magisk V18.0.

Everything works, root, no probs with camera.

My question: Can I simply flash your kernel (boot.img) with TWRP and try it?

Can I flash back the current boot partition if I want to?

(I really don’t want to wipe my device – to much work to restore everything…)

Many thanks in advance!
[Sony Xperia XZ1 Compact ROMs, Kernels, Recoveries,] Alvian_P:
Yes it can. I flash this kernel with twrp
[Sony Xperia XZ1 Compact ROMs, Kernels, Recoveries,] Timo.Deseniss:
Thank you Alvian_P.

I tried tonight – worked flawlessly!

Had to flash Magisk18 again afterwards, which makes perfect sense.

Nice and easy method.

Janjans Kernel is installed now, no problems so far. :)

Now hoping for a version for the new 47.2.A.6.30.
[Sony Xperia XZ1 Compact ROMs, Kernels, Recoveries,] sharvilsp:
dm-verity issue

I tried flashing the latest (47.2.A.4.45) image but when I go to the file manage in TWRP, I just see garbled folders (like 35u9u32u09gfsdjr235). I think this is a dm-verity issue but I'm not sure.

I used Xperifirm to get Nordic Firmware (G8441_Customized NOBA_1311-0104_47.2.A.4.45_R1C). I then deleted all .ta files + fwinfo and ran newflasher.

Then I used fastboot to flash twrp 3.2.3 lilac and finally flashed the boot.img from 18/1/2019. I then rebooted my phone.

When I go to TWRP it doesn't let me access the internal storage of the phone. What am I doing wrong?
[Sony Xperia XZ1 Compact ROMs, Kernels, Recoveries,] gladykov:
1. Do not delete anything from downloaded firmware. Deleting *.ta files is an old myth (caused me headache once) and first time I hear about deleting fwinfo

2. Make sure you have twrp-3.2.3-0-lilac-pie-2.img

3. After installing trwp do not flash kernel - check if you can access internal storage of the phone there - if not, then ask in trwp thread

4. If you can see it, flash kernel and let us know :)
[Sony Xperia XZ1 Compact ROMs, Kernels, Recoveries,] tonsofquestions:
If that's the case, then why does newflasher specifically ignore all the .ta files?

Flashing the wrong ta file can do things like simlock your phone (simlock.ta).

Some of them are innocuous, but some definitely have the potential to cause harm.

Just like persist.sin can cause harm:

https://xdaforums.com/android/general/info-android-device-partitions-basic-t3586565

There's a whole thread about the attest keys:

https://xdaforums.com/xperia-xz1-compact/help/android-attest-key-lost-bootloader-t3829945

That are *lost* if you flash the persist.sin partition.

So while I agree it's a little overblown to not flash *any* of the ta files, I strongly disagree with the suggestion "Do not delete anything from downloaded firmware. "

[Sony Xperia XZ1 Compact ROMs, Kernels, Recoveries,] Grogen:
Good kernel, but I have a question related to DRMfix. I expected it to fix all the issues with DRM, but I found out that "video image enhancement" option is not working, Is there anything else I need to do to make it work other than flashing kernel? Does it fix this at firsst hand ?
[Sony Xperia XZ1 Compact ROMs, Kernels, Recoveries,] megaice:
Hi, quick question. I wanna try 47.2.A.6.30 but when downloading firmware (xperfirm - flashtool 0.9.25.0) there's no .fsc script for 47.2. How do you flash? OTA? (because latest firmware is 47.2.A.8.24)
[Sony Xperia XZ1 Compact ROMs, Kernels, Recoveries,] Timo.Deseniss:
You can use the same script as for 47.1 firmwares.

Just go to C:\Users\%username%\.flashTool\devices\G84XX and rename 47.1.fsc to 47.2.fsc (or copy it).

Worked flawlessly.

Hi experts, I have a question to those who had the boot loop problem: did you solve it somehow?

I have a bootloop now :crying:

Flashed recovery using twrp-3.2.3-0-lilac-pie-2.img, then booted into TWRP and tried to install magisk (tried versions 16 and 18). First there was an error that Could not mount system - had to change filesystem to ext2 and then back to ext4 and this solved this error. Now the Magisk installation fails with error "unable to repack boot image" and I can boot only to TWRP.

Then tried flashing boot using all of the boot.img files mentioned in this thread, but none of them did any better.

Any suggestions to fix this are welcome. Thank you for reading this far.
