Hello,
I have quite a serious problem on my LG G3. The headphones icon is always showing, and now if I move the headphone jack slightly, the track either pauses or skips. This happens on all audio players, not just stock Music and Spotify, so it is likely a kernel IRQ doing this.
Brief background: I am familiar with the Linux kernel and I'd like to chase down this 'behaviour' with a few printks and patch the kernel to ignore this. My phone appears to be water damaged (apparently) and the repair co will not touch it.
Where can I find the stock LG kernel sources for G3? I see other kernels like the sharepning one but I would like to take a vanilla tree and work on the kernel myself.
Build process looks like: use a CC (already set up), 'Bump' and then flash it with the LG tool? Correct?

And yeah, cross compile it, bump, "flash" the resulting image via dd or create a flashable .zip with it.

Hang on -- are they violating the GPL here by producing binaries but not updating the source..?
re. dd -- that's a nice way to do it, do I plug in a microUSB and set up the G3 to expose itself as a block device so I can do this, or did you mean run dd from the unit itself.

I'm not a lawyer, but it surely seems like it.
dd from the unit itself.
adb push kernel.img /sdcard/kernel.img; adb shell "dd if=/sdcard/kernel.img of=/dev/block/platform/msm.sdcc.1/by_name/system; reboot;"
i may have misspelled path to partition or adb push/shell order of arguments and syntax, but i think that you got the idea

Same Problem here.
Do you have an original HTC s620? I use XDA Cosmo from o2 Germany. I thought it may be could be an issue for my brand. My ROM-Version is 1.13.207.2
This makes it impssible to update exsiting contacts.
Do others experience the same?
Hi,
I just got a new phone, a UTC touch but its in Chinese, is it possible to change it to English?

If you meant the HTC Touch, you might try looking into an HTC Touch ROM from the ELF(another name for Touch) section of the forums. Make sure you have a way of switching back to your ROM in case something happens though.
The link is here in case you're new to the site:

You should ask on the elf section if you'll need to install anything prior to flashing . I own a mogul so I don't know the details of your phone. They should be happy to help you the rest of the way in the elf section.
Just a copy for you of an information given by "Segfault" in a german board:

I think it's another 2.2 release...
I think (or fear) so, too.
After encrypting the *.zip.enc-file the result is (packed in the usual zip-fale) the following:
JPO_JP3_U_JPP.tar
SS_DL.dll
kinda weired...
If you're in the USA, TWRP and root are available for you here - but only if you have the KIW-L24 model:
[TWRP] for KIW-L24 USA (kiwi)
^^ That recovery is not recommended or tested for any version other than KIW-L24 as of February 10, 2016.
So here's the situation:
We may be able to support other versions for international users
We make no promises
We are providing a tool and instructions for you to give us the information we need about your version
We make no promises
You MUST give the information exactly as we request
No personal information is being gathered - none
We've made it as easy as possible, you don't have to be an expert
We may have to come back and ask you for more information
We make no promises
But we are willing to try if you want to help
Instructions:
Download the attached zip file and unzip it on your phone - ES File Explorer or equivalent is fine
Run the script: find-honor.sh
Copy the contents of /sdcard/found-honor.txt to http://hastebin.com
Post the link to your hastebin here in the thread
DO NOT post the output here - we're not going to manage to that - only post your hastebin.com link, ok
You may run the script however you like:
adb shell or Terminal Emulator
or just use SH Script Runner (instructions on that will come later in the thread)
Shell/terminal instructions:
cd to the folder where you unzipped the script
Execute the following command:
source find-honor.txt
How to upload:
Go to the found-honor.txt file in your file browser
/sdcard, /storage/emulated/0 and Internal Storage all mean the same thing on your phone
Open, select all, copy
Paste and save to hastebin.com
Pictures follow, in my example I use the built-in Files app
Go to the internal storage, tap on find-honor.txt
OK to open Just Once with HTMLViewer
Long press any word to get menu on bottom
Select all, then copy
Goto http://hastebin.com and paste
Find the disk image in the upper right corner to save
Post the link
Your output will look similar to http://hastebin.com/norufikubu.avrasm

Welcome to the forums.

Another 2/16 KIW-L21 - thanks!
@WidosFTW or @racing2410
Per suggestions from the team (shm and Ncypt3d) after reviewing your data, we've decided to update the script because we don't want to take the chance relying on the honor website specs.
Please refer to the following picture from the app CPU-X in the Play Store:
The top of yours ought to be similar and say MSM 8939 HUAWEI KIW-L21 (where mine says L23).
If there is any doubt, please erase the old find-honor.sh on your phone, get the new copy from the OP, and repeat the process for us.
Many thanks!
ok lets see

From what i can tell from the info provided the L24 twrp recovery should work on L21.
Here is the official L24 twrp:
https://dl.twrp.me/kiwi/twrp-3.0.0-0-kiwi.img.html
Stock L21 recovery encase it does not work:
https://www.androidfilehost.com/?fid=24411628330025737
If there is a error please put as much info as you can get and pictures if possible. Also attach a recovery.log so we can double check everything is working.
ok i will try to flash the recovery after work. first i have to unlock my bootloader :angel:

The installation works fine and it also starts the twrp but you cant use it properly because you get the touchscreen error, which was already described in the US Thread. I dont know where the recovery.log is so I cant post it here. I somehow managed to install root but I would consider this unusable.
Edit:
Found the log, it is in the attachments.
Can confirm. Installing TWRP was fine, but it can't be used (touchscreen does not recognize input)

You mentioned that you were able to use the debloat method on your KIW-L21.
Did something change on the touchscreen usability or can you elaborate for the benefit of us and others?

Someone in the main thread posted that you have to tap the screen extremely fast and that the issue is most likely a bug in the TWRP software (not waiting long enough for user input or something). It worked this way but is extremely luck based. Like I had to try and flash the zip file 10 times before I was able to slide the slider while not having the archive validation checkbox checked.
Selecting the "install" button and the archive itself also took a few minutes. Basically you'll have to hammer your screen at 5 touches per second or something for it recognize
Same with me it took me about an hour to get it working.
We've been discussing the touchscreen among ourselves and your feedback may help - thanks!
Sent from my KIW-L24 using XDA Free mobile app
Do you still need ppl to run the script for the L21?
Please read this entire post before doing anything.
Pretty straight forward modification that will increase performance and save battery life. You must be rooted to apply this.
Drop this file: https://drive.google.com/file/d/1h0ET7pYHdPB32v-ZtK5pEMlwlHNn8O46/view?usp=drivesdk
... into this location (replacing the existing stock one):
Code:
/system/vendor/bin
Basically, there is a file in that sub-folder "init.qcom.post_boot.sh"
You are replacing that file with mine, which I've made the following changes to:
-modified hispeed_freq and hispeed_load parameter for both CPU clusters so they run more efficiently
-modified vm parameters in /proc/sys/vm to allow a little more RAM to be used. USE YOUR RAM, that's what it is for! I don't like having a full 900Mb of free RAM, then having apps refresh when they are opened again.
-added a script to limit the maximum display brightness (this is still very usable, but it will be more power friendly. The stock settings are way too aggressive)
- there will be much more to come, this is just to start us off
Also, after you drop the new file into the folder, change the permissions to:
Code:
rwxr-xr-x
then reboot/power up
The .sh file executes on its own after each boot. No more CPU apps.
You will see a noticeable difference in battery life and performance. :good:
Yes could you please give me step by step on how I post apply this to my device because I cannot give it permission and then when I do get to permission changed it keeps saying that ignore it it snow please help

SMD632 is the ID.
Pretty sure yours is SMD636
replace file let's see if anything improves
original file has size 200k
your 41k
restart system has again 200k
this is normal ?
How is this working for those that have used it?
I'm curious too..I've benchmarked my G7 and got a baseline for performance and will eventually try this to see if it improved things..but first I plan on trying some of the tweaks available in Magisk.
this mod doesn't seem to stick as it always reverts to the stock file. why not just make a custom flashable kernel?
Is there guidance to make the change persistent after a reboot. This is my first A/B device and things seems little different now. I am unsure if Motorola is restoring the vendor partition or if the reset isn't related to something else.
I've been trying to avoid installing TWRP due to lack of development and was hoping to apply this with either the stock recovery of just in the file system.
*edit.
I guess Ill look into disabling dim-verity without TWRP, I think I saw a way to do it. Or maybe boot TWRP from the command line instead of installing it.
I made a magisk module to load this file.
See Page 2 to download.

Without anyone making twrp flashable zips of the updates I am remiss to install it. If more mods come along that require workarounds like this one I will pull the trigger but for now, this one change does not warrant TWRP for me anyway.
