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?

Of course, they uploaded nothing.
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

Thanks, this is great

INFO
I sold my P10 Lite, based on Huawei's decision to no longer provide bootloader unlock codes.
For a generic version of this project (ADB-Overlay) have a look at this thread.
The latest build of this project is still available.
---
Hello together,
here is a toolkit for the P10 Lite, it's designed to work primary with root (THE MOST TIME) so be careful what u are doing, specially if u are using the "Explorer". (Deleting the wrong file/folder on root lvl, could bring u in bad trouble!)
-
To all who used already my P9 Lite toolkit, there is currently not all available which u know from the old version, but i'll extend this toolkit in the next days. So, no worries about missing functions, they'll appear in some of the next builds.
-
About the usage,
- For a basic UI-Help just press F1
- If ur device is not detected u can switch off the "Device check" on the "Disclaimer" view (If u own a P10 which is not detected pls share a screenshot of the "adb devices -l" (l = lowercase L) command)
- U can also switch the (su -c) usage off (in the explorer view), BUT! after u performed any action which requires root, the trigger will be automatically switched on. (There is no other option, because my dll know only, use root or don't do so... There is no use root part-wise)
But anyways, i'm NOT responsible for any damage to your device!

Version Information
Status: Stable
Current Stable Version: 0.0.0.5
Stable Release Date: 2018-08-01
Created 2018-03-30
Last Updated 2018-08-15
How-To
[Q:01] My device is not recognized by the toolkit?
1. Make sure NO adb-server is running!
2. U need to start ur device in android with enabled USB-Debugging (see the screenshot)
(Only in adb mode my toolkit can detect ur device)
3. Make sure that u granted adb access on ur device
(A popup will appear on the device and asks u to grant access.)
Try also to restart the toolkit after u granted access on ur device.
U can also check the device state by opening a cmd/terminal prompt and typing:
Code:
cd path\to\the\toolkit\adb
adb devices -l
check if ur device is listed as follows:
XXXXXXXXXXXXXXX device product:WAS-Lxx model:WAS-Lxx device:XXXXXXX
If ur device can't boot into Android or still didn't get detected, well, just deactivate the "Device Check" on the "Disclaimer" tab. And follow the description.
[Q:02] What does the Lxx Cxxx Bxxx mean?
The Lxx is the device model, the Cxxx is the region/operator identifier and the Bxxx is the build number.
Here is a short list about the regions/operators
ID (Cxxx) = Region/Operator | custom.bin (content)
----------------------------------------------------------------------------------------------------------------------------------------------------
C02 = Vodafone
C10 = Russia
C21 = Telefonica / O2
C40 = Czech Republic Telefonica / O2
C55 = Italia TIM
C66 = VIPmobile | vip/rs
C86 = Spain Yoigo
C109 = Amena/Orange
C112 = Latin America
C113 = Wind/Italy | wind/it
C121 = Türkei
C123 = Switzerland
C150 = T-Com | dt/de
C151 = India
C185 = North-Africa/Middle-East | hw/meafnaf
C209 = Asia (Pacific)
C212 = Iusacell/Nextel
C249 = Serbia Telekom
C432 = Nordic-European | hw/eu
C470 = Asia (Pacific)
C605 = Colombia
C637 = Spain
C636 = Asia-Pacific | hw/spcseas
C675 = India
C706 = New Zealand
C900 = GLOBAL
More comming soon...
Big THX for some of those "identifier" goes to:
@lost3
@baduncle
[Q:03] I want share my custom.bin & oeminfo, what i need to do?
U can get the files via the "Dual-/Single-SIM -> Export" or u can do the following steps (root required).
Open an terminal/cmd prompt and navigate to ur adb installation or the toolkit directory (path/to/the/toolkit/adb) and type the following commands.
Code:
adb shell
su
cat /data/custom.bin > /storage/emulated/0/custom.bin.bak
dd if=/dev/block/platform/hi_mci.0/by-name/oeminfo of=/storage/emulated/0/oeminfo.img.bak
exit
exit
adb pull /storage/emulated/0/custom.bin.bak custom.bin.bak
adb pull /storage/emulated/0/oeminfo.img.bak oeminfo.img.bak
Now u have 2 files, the custom.bin.bak and the oeminfo.img.bak just zip them and upload them to GoogleDrive or DropBox, etc. and share the link in this thread.
[Q:04] How can i manually boot into a specific mode?
Bootloader:
[device] = Turn the device off - Connect it to the PC - Press and hold: [Vol-]
[adb] = adb reboot bootloader
[fastboot] = fastboot reboot bootloader
E-Recovery:
[device] = Turn the device off - Connect it to the PC - Press and hold: [Vol+]
[adb] = N/A
[fastboot] = N/A
Recovery:
[device] = Turn the device off - Disconnect it from the PC - Press and hold: [Vol+ Power]
[adb] = adb reboot recovery
[fastboot] = N/A
Normal Boot:
[device] = Power button / Power button menu
[adb] = adb reboot
[fastboot] = fastboot reboot
Update Mode:
[device] = Turn the device off - Disconnect it from the PC - Press and hold [Vol+ Vol- Power]
[adb] = N/A
[fastboot] = N/A
[Q:05] Does the Dual-Sim upgrade survive an OTA?
Yes, the Dual-Sim modification will stay until u flash another oeminfo.
[Q:06] I upgraded to Dual-SIM and there is only one IMEI shown?
That's absolute normal... Because, u had a single-sim device before, so the device hold only one IMEI and the 2cd sim will use the same IMEI as the 1st sim or as shown the "0000000000000000".

Bug-Tracker
*FIXED in 0.0.0.2
- Noticed already the missing icons in the "Explorer" (Big Icons + List)
(Bug is already solved and will be fixed in the next version)
Known-Issues
- The "Explorer" "Big Icons" looking a bit ugly, that's because the p/invokes won't give me the "Extra Large" icons... I still work on it, so maybe it's fixed in the next version.
--
Drag 'n' Drop on any Explorer view, from outside the Application won't work until u run everything as Admin... That's a Windows UAC restriction and based on the fact, that we need the right's to create/delete/modify files/folders under Win8++ on the system HDD. (Like ADB pull for export of the oeminfo and custom.bin)
Missing Tweaks from the P9 Lite Toolkit
- As the screenshot shows, i managed to activate the "Double-Tap" menu, but that's all... The Double-Tap it self doesn't work... So there will be no "tweak" for this. - (Additional Info: The Double-Tap works^^ But ONLY on the lock-screen... And ONLY to turn the screen off... What a joke...)
- USB-OTG, is not available because, so far i know, u need a special kernel for it. (Which i can't provide, atm)
- AppTwin, because it should be enabled on any P10 Lite by default
Little - Update (1+2+3+4)
- I added a screenshot of the upcoming release, with integrated "Phone" control. (Currently only Call/Dial works)
- Added another screeny, now (Call/Dial/Add) is possible. Add, needs still interaction on the device side, like which "provider" (Device, Google, etc.) u want to choose. Dial, will insert the number in the default dialer, or it gets captured by any USSD protection. Call, will immediately start a call to the provided number.
- Just tested to send USSD-Codes like "*#06#", but it seems that u really have to type them... Even sending "*#06" and manually type the "#" doesn't work... U have to delete and re-type the whole USSD-Code...
- Added the final look of the "Phone". (At least, Add, Call, Dial, Hang-Up) is now possible.

Dear Developer!
I suffering with a strange problem, i also opened a question thread about:
https://forum.xda-developers.com/p10-lite/help/please-help-fix-issue-t3805333
I'm not tried your toolkit yet, but i guess it maybe could help me... First: I would like to ask you what do you think about my issue(?). Probably you are much more technical than me, if you were able to create a toolkit for p10 lite... Should i try to fix my phone with your toolkit or can you suggest me any method? Do you have any idea what I could do?
Thanks you in advance!

Use only stock ROMs for now, cuz there's no daily driver Customs for P10 Lite yet. Stock Oreo is really good. You can use HwOTA to flash stock ROMs.

Heyho,
the "NRD-testkeys" are normally an issue with the "cust" partition. That means that ur oeminfo doesn't match with ur "cust" version. Let me explain... If u switch from SS to DS u change the device model (ID - Lx1 -> L21) this causes some problems on the "cust", because there is only one folder existent. The folder matching to the device u had before the switch. So all settings like "phone/umts" etc. are now invalid and can't be found under this model (ID). Because the folder simply doesn't exists.
How to fix it?!
U have to install/flash a complete stock rom via dload. - Get u FOR EXAMPLE an oeminfo like "L21AC432B183" and the rom "L21AC432B183", now u have to flash the oeminfo and straight after it, via dload, the FW upgrade.
-
During the flash of the "L21AC432B183" the system will check that u have "now" a L21 and will align the "cust" to that device.
Hope i could help u to understand how things work
Regards,
Sebastian

just a quick question: lx1 is single sim and l21 for dual sim?
Because i had a dual sim model but my sw version was lx1
did i misunderstood something?
btw, i having a very strange problem with the phone, out of the box. seems like a sw render problem. for example in nova launcher i have strange animation distortion and diatorted masking. i was hoping it will be fixed too with changing the rom but this problem still exist.. do you thing it can be because of some wrong factory software inatallation?

Heyho,
np
-
Yes, the "Lx1" are always the SS and the "L[1-9]1" are the DS variants. - Btw. u can't see the "real ID" under "Settings -> Info" to see the "real ID" u have to look in the "current" oeminfo.
-
I wrote a tool for this kind of tweaking/exploring, have a look at it, u can get it here
EDIT:
About the issue with the display/animations, it could also be a problem with the HW... I have seen a few forum posts about "factory delivered" broken chips etc.... Maybe there is something else wrong, if it was really from the 1st day u got it.

Sebastian

I guess your Q&A kind of answers my question, though I want to be absolutely sure:
Sharing your oeminfo (and/or custom.bin) file(s) with others, does not give away any personal/unique info. I checked my oeminfo with a HexEditor and it seems to include my Firmware upgrade history (at least the last two updates), IMSI (only SIM/Network Operator - unless I overlooked something), and those hmac/&token values. With these infos nobody should be able to "do bad stuff" - am I right?
Please correct me if I'm wrong. Thanks in advance for any input, cheers!

Heyho,
if you would have used my OEMInfo Tools, you would have seen that those values are no secret.
-
For example, the FW builds are needed to determine the current OS and if needed, the fallback/restore versions. Also the HMAC is needed for the OTA (the HMAC is used in conjunction with your IMEI, so the HMAC alone, is worth nothing). There is also a "Tamper-State" when and how often you unlocked/rooted your device.
But so far i saw, there are no "personal" data, like the IMEI or the SIM-Card Number. Maybe they are stored as one of those checksums (md5/sha1).

if you would have used my OEMInfo Tools, you would have seen that those values are no secret.

For example, the FW builds are needed to determine the current OS and if needed, the fallback/restore versions. Also the HMAC is needed for the OTA (the HMAC is used in conjunction with your IMEI, so the HMAC alone, is worth nothing). There is also a "Tamper-State" when and how often you unlocked/rooted your device.
But so far i saw, there are no "personal" data, like the IMEI or the SIM-Card Number. Maybe they are stored as one of those checksums (md5/sha1).

Thank you very much for clarifying and shedding some light on this, Sebastian!
From what I've read, reconstructing (files) from checksums doesn't (really/easily) work - though in theory (if enough additional parameters are given, and IMEI/IMSI are kind of short strings) it could be reverse engineered - unless I interpreted my research findings wrong :victory:
I assume it's safe though

Hi world(first post since android(previous windows mobile member of xda)),
I have P10 lite for almost a year(not rooted for warranty issues).
I wanted to perform a stock firmware backup before I endulge in rooting/custom ROM.
Is that possible with TWRP(with or without rooting), and are there any how-to's?
Sorry for being such a newbie, just like to upgrade to 8.0 and revert back to stock in case of a problem or warranty issues.
Thank you.
