I'm working on merging all the fixes for the linux kernel into Samsung's source code.

If you don't know how to build the kernel, this project is NOT for you. But have a recovery image anyway. Its the stock with only the kernel replaced, but that's so I have a stable development platform.

Features

* git history (mostly done via looking at the Makefile and copying everything over the source tree)

* Easier upgrades to newer minor releases (3.4.XX)

Installation

$ adb reboot download

$ heimdall flash --RECOVERY ${PATH_TO_RECOVERY_IMG}

Basic workflow:

# git merge v3.4.xx -- I'm doing it this way so that the changeset between builds is manageable (kind of).

# fix up compilation errors (show breaking) and then replace zImage in Samsung's recovery image. See if it boots into recovery.

# Reboot into regular mode, pull /proc/last_kmsg and check kernel version.

Notes:

Requires that gcc 4.6 is used

linux cannot be in the directory path (gets replaced with "1" by the graphics source code)

Doesn't work with repo. Sorry. I like gitlab better than github, even though I have accounts on both.

Changelog:

v3.4.67-lt02wifi:

Updated to android-3.4 master

[new] Modified ion code (took upstream code, for most part -- main exception is we used "heaps[]" instead of "*heaps"

[new] Marvell drivers can now be built into the kernel (obj-m -> obj-$(CONFIG_WHATEVER))

[fixed] CVE-2015-1805

[fixed] Most kernel CVE's

v3.4.34-samsung:

Updated to v3.4.34 from v3.4.11

[new] Completely replaced net/ipv{4,6} code

v3.4.11-samsung:

Updated to v3.4.11 linux stable source

v3.4.10-samsung:

[new] Updated to v3.4.10 from v3.4.5 stock sources

My NEXUS 5 just recently starting giving me issues, battery draining about 15% per hour (without use) takes about 4 hours to charge and I cannot adb into device (computer does not see it at all) ive tried multiple cables and I have the original charger plus many after market chargers in good working order. I can get into TWRP and flash roms but no matter what i do results are the same. (marshmallow rom currently) could my usb port be suspect?

Any help/suggestions would be greatly appreciated

thanks in advance
[Nexus 5 Q&A, Help & Troubleshooting] jsgraphicart:
ADB or Fastboot? If your phone is on and booted up and you are trying to run ADB commands, click on the notification that tells you what mode you are in. I think by default it is in charging only mode. Tap to change modes and select PTP. I think that's what it is. Then your computer should see it.
[Nexus 5 Q&A, Help & Troubleshooting] dahawthorne:
Probably a driver problem. Have you changed laptop/OS recently? Try installing on your PC Wugfresh's Nexus Root Toolhit and following the instructions in Install and Test Drivers - the long button top right.

Doesn't see it in MTP, PTP or charging mode, it use to in both, not a driver issue either. I have 3 other Nexus 5's and 2 nexus 7's in the house I've done flashing both via ADB through windows and with TWRP there is definitely an issue I just can't figure it out

from my experience a really good one. It locks on in TomTom in about 20 seconds and routinely gets 9 or more sats. No its not the sirf 3 one, but who the heck cares, this is a phone not a laser guided missle system ;)

my note 4 was on bobcat rom and then it got black screen so i sent it away for repair to vodafone who sent it back after fixing it saying that some electric malfunction had caused screen to stop working,

they had installed stock 5.1.1 on it somedays later it gave message that phone too cold to charge and i had to try over n over n then it would charge sometime then this got fixed itself somehow but a few days later the screen went black again,

sent for repair 2nd time but sent back saying warranty void as knox tripped now i would be happy and contended if i knew that its a faulty electric part that blows up screens n its the end of the line for me with this note 4

but the damn things works intermittently whenever it wants for however long it wants then it heats up too much and then screen flickers ,reboots n t its black screen again..after that it boots up n i can hear sounds n touch feedback and all but wont be able to see anything on the display for a few hours/days/weeks n then the same over again..

any ideas of any kind ,hardware/software would be appreciated thanks ,cos i cant even get it repaired given its erratic moody behaviour thanks .
[Xperia Z3 Compact Q&A, Help & Troubleshooting] quarrymanpaul:
Did a search but surprisingly couldn't any similar threads.

My USB port has become gradually looser to the point that charging it means resting the phone in such away that it applies pressure to the USB connection for it to make contact and charge the phone.

Initially some cables worked better than others but they are all starting to fail now.

The magnetic port has also failed. Does anyone have a solution for fixing the USB port?
[Xperia Z3 Compact Q&A, Help & Troubleshooting] StaticGTF:
Hi

You'll probably have to send your phone to a repair center to replace the "exhausted" usb-port. If you are handy with a soldering iron and have the guts to crack your device open, you should be able to acquire the parts ad i.e. eBay or some such and replace the port yourself. Can't be too hard seeing as it is only a four or six-pin connector that attaches to the board...

Can't figure out why the magnetic charging-port won't work though...
[Xperia Z3 Compact Q&A, Help & Troubleshooting] quarrymanpaul:
Hey. Thanks for the reply.

I used a magnetic connector that was too powerful I reckon and eventually pulled out the magnetic port. I glued it back in but was never the same after that.

On the USB port, I have the phone for 18 months - should I be able to get it repaired under warranty?

[Galaxy S 4 Q&A, Help & Troubleshooting] Dr Goodvibes:
Using Odin you should be able to downgrade directly to Android 4.3

You will have to do a factory reset in recovery.

I did my factory reset after downgrading the firmware, but guessing you could do it before the downgrade and then not have to worry about the auto-reboot in Odin.
[Galaxy S 4 Q&A, Help & Troubleshooting] davidgozman:
Hi

I have a problem during flashing from 4.4.2 to 4.3. After start the process fails by aboot.mbn. If I remove the file aboot.mbn in the md5-package and start the process again, it works. The mobile flashs back to 4.3, but it hasn't sound and I can't record Video or Soundmemo. Please help! I don't what to do.

I'm looking forward.

[Galaxy S 4 Q&A, Help & Troubleshooting] audit13:
Aboot.mbn is the bootloader. You cannot flash a 4.3 bootloader over a 4.4.2 bootloader.
[Galaxy S 4 Q&A, Help & Troubleshooting] davidgozman:
Is there any way to go around the bootloader? Would it help to flash lollipop 5.0.1 and then to flash back to jelly bean 4.3 or the lollipop has a bootloader locker too.

Thank's so much!!
[Galaxy S 4 Q&A, Help & Troubleshooting] audit13:
There is no way to downgrade the bootloader to 4.3 once the phone has been flashed with 4.4.2 or newer. This applies to many Samsung phones including the s3, note 3, note 4, etc.
[Galaxy S 4 Q&A, Help & Troubleshooting] davidgozman:
I flashed my S3 from 4.4.4 to 4.3 and tab 3 from 4.4.2 to 4.2.2 without any problems...why it doesn't works on S4?
[Galaxy S 4 Q&A, Help & Troubleshooting] audit13:
Are you sure that the ROM you used to downgrade included a bootloader?

For the s3, it may be possible to go to a 4.3 bootloader as there was no bootloader after 4.4.2 but I'm not 100% sure. I have no idea about the tab.
[Galaxy S 4 Q&A, Help & Troubleshooting] davidgozman:

[Galaxy S 4 Q&A, Help & Troubleshooting] audit13:
You installed the 4.3 bootloader too? You may want to run Samsung Phone Info from the play store to confirm.
[Galaxy S 4 Q&A, Help & Troubleshooting] davidgozman:
I'm not sure. I removed the file aboot.mbn and converted the md5 archive to tar archive and finaly flashed my s4. It works, but there's only no sound in thy system.
[Galaxy S 4 Q&A, Help & Troubleshooting] davidgozman:
I'm not able to downgrade it from lollipop too. I haven't the option to unlock the oem in the developer options
[Galaxy S 4 Q&A, Help & Troubleshooting] audit13:
The OEM unlock bootloader option is only useful where a phone has a locked bootloader. In the case of your s4, the bootloader is not locked and cannot be downgraded.

The aboot.mbn file is the bootloader and removing it means the phone is running a 4.3 ROM on a 4.4.2 bootloader. This is probably why not every works properly.
[Galaxy S 4 Q&A, Help & Troubleshooting] davidgozman:
How can I solve this problem?
[Galaxy S 4 Q&A, Help & Troubleshooting] audit13:
You can solve the sound problem by flashing a newer ROM.

You cannot downgrade the bootloader and trying to downgrade may brick the phone by damaging the bootloader.
[Galaxy S 4 Q&A, Help & Troubleshooting] davidgozman:
Why it worked with tab 3 and s3? I saw many videos on youtube, there rolled guys the system back...Well, Ithink it's my fate to have the kitkat. I hate this system.
[Galaxy S 4 Q&A, Help & Troubleshooting] audit13:
The s3 and Tab 3 are totally different items. Being able to downgrade a bootloader on one device does not automatically mean every bootloader in a company's product line can be downgraded.

Have you tried running a custom ROM on the phone? You may find those more palatable.

I went through the same issue with another XDA member that wanted to have a 4.1.2 bootloader on his note 2. His Samsung note 2 was running a 4.4.2 bootloader and wanted to go all the way back to 4.1.2.
[Galaxy S 4 Q&A, Help & Troubleshooting] davidgozman:

Is it able to flash a firmware to a Live Demo version?
[Galaxy S 4 Q&A, Help & Troubleshooting] audit13:
I think it will be very difficult to find a s4 running 4.2.

I don't think live demo phones can be converted to a regular phone.
[Galaxy S 4 Q&A, Help & Troubleshooting] davidgozman:
If it's unpossible to roll back s4, why there are many firmware for download available?
[Galaxy S 4 Q&A, Help & Troubleshooting] audit13:
So people can upgrade the ROM when ota updates don't work, update bootloaders and modems without having to perform a full flash, going back to stock from a custom ROM, etc.
[Galaxy S 4 Q&A, Help & Troubleshooting] davidgozman:
Ahh, so if I had a S4 with stock 4.2 and upgraded it to 4.4.2, then I was able now to roll it back?
[Galaxy S 4 Q&A, Help & Troubleshooting] audit13:
No, if you had an s4 with 4.2, you could roll back to 4.1.2.

Once the phone is running a 4.3 or 4.4.2 bootloader, can't flash a 4.2 or 4.1.2 bootloader anymore.

[Galaxy S 4 Q&A, Help & Troubleshooting] audit13:
Not sure what you mean by the word "locker".

It has Knox on the screen which means it is running at least a 4.3 bootloader.
[Galaxy S 4 Q&A, Help & Troubleshooting] davidgozman:
see my screenshot. have the three lines with knox and csb config lsd
[Galaxy S 4 Q&A, Help & Troubleshooting] audit13:
Those lines do not mean that the bootloader can be downgraded. I looked myself for many months and could not find an instance where a downgrade was successful.

Did you find any posts from anyone that was able to flash a 4.1.2 bootloader over a 4.3, 4.4, or 5.0 bootloader? The YouTube videos haven't demonstrated to me that the bootloader was downgraded and only the rom was downgraded.

To satisfy yourself, you could follow along with the YouTube videos; however, trying to downgrade the bootloader can hard brick the phone.
[Galaxy S 4 Q&A, Help & Troubleshooting] davidgozman:

I want to delete the actual operation system complete and set a new one. Is it able to make that?

What about a custom rom? If I'll install a custom rom, I'll get an unlocked bootloader. I read it now in a german forum.

That's right or I didn't copy anything?
[Galaxy S 4 Q&A, Help & Troubleshooting] audit13:
Not sure what you mean by "make" a new system. You mean factory reset? I don't see why not. It wipes everything and you have to go through the set up routine.

I recommend that you determine what you want to accomplish and then search for methods to help you achieve your goal. There are many helpful threads on xda about this phone.
