A ROM with few or minor security patches.
Essentialy for doing things not allowed in released firmwares.

Kernel Appreciation Thread

I've scavenged the forums for kernel images in circulation and gathered a rather considerable collection of them. Here's the whole list, also including stock kernels for comparison (starting with 1.0.1, as this is the earliest version I have access to). I don't have direct links (didn't save them as I went on my collecting spree) but I renamed the files by the poster's name and the date of their post so each file should be easy to find through search. I also removed any duplicates (reposts).
The list is not by any means complete, and updates are most welcome but hopefully it's a good starting point, and others will find this summary helpful.
Using this thread you can identify if a kernel found somewhere else is the same as one of the "well-known" ones. The best way for this is to check the MD5 sum unless the file sizes obviously differ. Along with the kernel image list, there is also a comparison of other boot-related files (aka "the missing changelog") below.
Kernel Images (uImage)
All images in circulation seem to be based on Linux-2.6.29-omap1. The format of the data is as follows: the first column is the normalized filename (post date in YYYYMMDD format followed by the poster name). The second column is the creation date as recorded in the kernel (pulled from the image with mkimage -l). The third column is the image file size in bytes, and the ultimate, fourth column is the MD5 sum of the file.

Recovery Kernel Images (uRecImg)
The recovery kernel is always the same as the main one, unless you use a custom recovery. Among custom recoveries, Clockwork RC2 uses uImage-stock-110. For Noogie and NookManager 0.5.0 it seems to be something else than the other images I discovered (see above).
Recovery RAM Disk Images (uRecRam)
For obvious reasons I am limiting myself to stock images here. The missing changelog:

Wrap-up
I started collecting this information in particular to reach some conclusion which kernel would be best for my purposes [for the record: (i) looking to squeeze as much as possible from the display with NoRefresh or FastRefresh, (ii) performance optimizations if stable and without impact on battery life, (iii) no need for USB host but OK if not a drain on batery, (iv) GlowLight support not a factor as my device doesn't have one, (v) SDXC Class 10 support also not a factor]. At this point I don't see a strictly dominating choice. I'll edit the post when or if this changes.

Windows 10 Mobile version 1511 codename Treshold 2 builds number + OS version

Because I was struggling to find them, I create a thread to offer the information I gathered.
So, here is a small list of the builds number and their equivalent OS version:
10.0.10586.0 -> 10.0.13052.0
10.0.10586.11 -> 10.0.13058.11
10.0.10586.29 -> 10.0.13065.29
10.0.10586.36 -> 10.0.13067.36
10.0.10586.63 -> 10.0.13070.63
10.0.10586.71 -> 10.0.13073.71
10.0.10586.107 -> 10.0.13080.107
10.0.10586.122 -> 10.0.13086.122
10.0.10586.164 -> 10.0.13090.164

10.0.10586.242 -> 10.0.13125.242
10.0.10586.318 -> 10.0.13169.318

need held building LOS16 with docker for unsupported device

Hi, I'm trying to build lineage 16 for my oxygen device. But after repo sync I'm getting this error:
/root/build.sh: line 141: [: $(PLATFORM_VERSION

>> [Sun Apr 7 06:12:21 UTC 2019] Missing "vendor/cm", abort
I can't find /root/build.sh and why is "vendor/cm" missing ??
why do I need this "cm" folder ?
I have the same problem as you.

~/LineageOS/16.0_microG $

where to begin to port to a newer Lineage Release?

Hey Guys,
i wanted to check what to do, for trying to port a newer Lineage release to this device.
Any hints where to begin?
I luckily compiled the 14.1 branch yesterday.
But what to do next?
Regards for the hints
I've been investigating this recently as well. I started looking at LineageOS 16.0 branch and the Exynos5420 kernal/rom code on github ("https://github.com/exynos5420"), as I am running a build on the tablet from here:-
"https://download.exynos5420.com/LineageOS-14.1-Vanilla/chagalllte/"
BTW, I'm a late/newcomer to android rom development, and I may be off track/incorrect anyways.
I've attempted building branch lineage16.0 with Exynos5420 and currently throws this error :-
bionic/libc/include/bits/fortify/fcntl.h:63:26: error: use of undeclared identifier 'O_TMPFILE'
__clang_error_if(__open_modes_useful(flags), "'open' " __open_too_few_args_error)
The bionic libc wants a definition for O_TMPFILE , I think is to be resolved from the
kernel headers under the kernel device tree at:- kernel/samsung/exynos5420/include/asm-generic/fcntl.h
Of course there is no definition of 'O_TMPFILE' in this header file.
Looks like a later linux kernel version (or patches) to the Exynos5420 kernel code/device is required with headers defining O_TMPFILE.
All I can suggest for porting a newer lineageOs is, get started experimenting/building.
Find/pick up a later device kernel source code tree
For me there is alot to learn and few up-to-date guides
Good luck

Add the following lines in the header file kernel/samsung/exynos5420/include/asm-generic/fcntl.h https://github.com/alexenferman/and...mmit/e97a38cefdb63305f85139c4409a597759388081 and you are good to go.
I tried compiling 16.0 for chagallwifi (T800) over the fall and ran into a number of compiler problems, but when I finally got it to compile, the resulting image wouldn't boot. A lot of those problems have now been fixed in gerrit.
I also tried 15.1 last week, but ran into a number of compile problems. Then I noticed a lot of activity on https://github.com/exynos5420 and https://review.exynos5420.com/ wrt to 16.0 so I tried again yesterday and today and I had to make 2 modifications for it to compile, but the result is an image that won't boot. The recovery image won't boot meaning somethings wrong with the boot/kernel stage.
Hopefully the team will make more modifications over the holidays and I will have a bootable 16.0 image?

Unpack the recovery and show me the files inside. You might be missing the init files on the recovery, like I did with the Snapdragon Galaxy S3

I have a 16.0 SM-T800 build booting now. Now I have to go through and see what works and doesn't work. This will take a couple of days.
I will also document what patches I needed to make this work not only for myself, but for other future builders.
Please join the exynos5420 team to contribute to getting LineageOS 16 fully functional.

What did you have to fix? I am building Los 16 for a Los 14 device too, kernel appears to be working, but it does not boot.

I will submit gerrit patches once the 16.0 code all settles down. There are camera + sensor + hal changes still to be merged. So far all bugs that I have found seem to be due to the pending or merge changes.
Some of the changes made to chagalllte weren't made to chagallwifi so it was relatively easy to copy them.

What device are you building for? Are you building for a tab S platform?
If a device doesn't boot, I find adb logcat very helpful.
I also use this utility.
Install logcat-colorize on Ubuntu using the Snap Store | Snapcraft
Get the latest version of logcat-colorize for on Ubuntu - logcat-colorize

yeah I only have a chagalllte so some of the other devices get overlooked.
As to what's currently not functioning:-
camera video recording
sensors /sensor hal may not be fully functional
RIL
+ whatever else I can't recall atm

by does not boot, do you mean it is stuck at the lineageos 3 rings startup animation?

What I found so far.
Doesn't work
1. home button doesn't wake up tablet. I think I know what is wrong and I'm compiling another new build, but it will take about 1 hour to complete.
2. screen rotation - which I think is due to pending merge hal/sensor changes
3. MTP, this could be due to my eng build for debugging purposes
4. camera - changes not merged. When I try a repopick -t Camera-Bringup, I get cherry-pick errors so I'm going to wait until it's all merged before I test camera.
Works
1. wifi (5 and 2.4)
2. bluetooth
3. brightness
4. external audio
5. audio through headphones
6. GPS - needs this yet to merged patch

I'm not a git expert. Everytime I use it, I struggle with the commands to upload patches. But most of the problems with chagallwifi are because chagalllte commits aren't applied to it which is understandable if the developers have the LTE version.
it will be very good to switch to Los 16 SM-T800 please guys continue

I also have a SM-T700 klimtwifi which I can build and test for. However, I have more than one SM-T800 so I will build for T800 first and get all the bugs worked out and then build T700 later.

Please can someone help me because I flashed this eng rom on my bootloader unlocked redmi Merlin with IMEI null issue, after flashing the phone stays in miui logo for ever. I have tried the versions of engineering rom available both here and halabtech site. The version of the current stock firmware on my device was V12.5.4. Please any help as to get the IMEI number of the phone back.
What is the difference between v1, v2 and v3?
Is there anything that specific one should be used?
