[Q] Stock kernel for COS12? - ONE Q&A, Help & Troubleshooting

Anyone have a flashable version of the COS12 kernel. AK Kernel keeps crashing my phone.

You should be able to extract it from the COS12 flashable zip, it's called "boot.img". Just flash via fastboot:
Code:
fastboot flash boot boot.img

boot.img?

Hey guys,
so right now I am trying to flash a new rom (currently on trickdroid) and was considering axiom but one of the steps is to flash the boot.img but i am having trouble figuring out how to flash the boot.img through fastboot. I have installed the sdk manager and htc sync according to the how to in the development thread. But i don't know where to get the file for the boot.img and what to do after that I have watched the video and read through the how to several times. Is there an easier way to go about flashing roms, or do I have to use the boot.img process?
If you flash via TWRP, you won't have to flash boot.img.
boot.img is found in the .zip package that you flash. It should be one of the first items you see when you open the zip. This is the .zip that you install when you're in CWM. Extract that boot.img for the fastboot method, but like I said, with TWRP you won't have to flash it.
Some people have said that their boot.img's didn't flash on TWRP, but worse comes to worst is you get stuck in a boot loop and you just flash the boot.img in fastboot or restore your phone in CWM.

How to get the original ROM back?

Well I need to send in the Chacha because of some Hardware issues, so I'd like to restore the original ROM.
What's the easiest way getting it back (maybe with the option not having to root it again afterwards, or restoring the Clockwork-Backup)?
The best way is to download RUU, extract from it rom.zip and from that zip extract system.img, boot.img and recovery.img. Then flash those three via fastboot using these commands:
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
And reboot your phone and you will have stock rom with stock recovery on it. Then you can use OTA update if available.

[Q] Restore stock recovery on Nexus 5

I am currently running CWM recovery and want to go back to stock recovery? How do I return to stock recovery? and where do i find the stock recovery file if I have to flash it?
My Nexus 5 is running android 4.4.4.
I have attached the ktu84p stock recovery image to this post.
Download the zip file and extract the recovery.img file.
Then use fastboot to flash it to your device:
Code:
fastboot flash recovery recovery.img

[Q] How to flash CM12.1 on new bootloader?

I can't seem to get TWRP or Cyanogen Recovery to flash succesfully CM12.1. They refuse to flash ROM zips, but do flash Gapps. I've tried ADB sideload to flash CM12.1, but ADB doesn't find my E3 no matter what I do. I go to recovery, and choose ADB sideload. Then I do adb devices and it just says "List of devices attached", but no devices. I can only use fastboot succesfully, which that made me think that I could decompress the zip and make the boot.img, system.img, and userdata.img out of it to flash through fastboot. I got all the required filesfrom the zip to make userdata.img and system.img (boot.img was already in there). I only have one problem: I haven't found a way to re-pack the files into the correct img format to be able to flash it through fastboot.
So, back to my question:
Has anyone managed to flash the CM12.1 zip successfully? If so, how?
Or, can someone show me how to repack the system files into system.img and the userdata files into userdata.img?

AOSIP install via fastboot conatains a system.img file instead of super.img

I downloaded the Latest AOSIP fastboot package to flash my X2 but sadly there is no super.img instead there is the old system.img. I tried to install it into Super by fastboot flash super system.img but the phone failed to reboot.
Now, I am back to my stock ROM and Recovery. Any ways I could fix this?

Don't think too much. Just follow the instructions from aospa thread.
