[Kernel] [Compilation] [Boot] SM-N910F

Hi,

I downloaded the SM-N910F kernel from samsung compiled and burned it with Heimdall. It works fine.
The problem I am facing is when I add some code into the kernel. It won't boot (returns do DOWNLOAD mode screen), error message "could not do normal boot".
Note: I have tried burning my boot.img both with Heimdall (linux) and Odin (windows), and get the same results, i.e. unmodfied kernel works fine, modified -- fails.

It seems to be a zImage size issue.
I tested this by only adding lots of seq_print(m ,"something somthing ....") in print_binder_transaction() (drivers/stagin/android/binder.c). just to make the zImage bigger (unmodified zImage size: 9792000 bytes, bloated zImage 9799072 bytes, only ~7Kb more).

I checked the with busybox fdisk the BOOT partition size, its 17MB.
I pulled the boot.img with dd from the device and used "abootimg -u boot.img -k ../arch/arm/boot/zImage" to update it with my compiled zImage.

any ideas?
missing info?

Thanks,
Daniel.

Overclock stock (Rooted) 851 (Can't find kernel)

Hey I feel like a noob for asking but after genuinely searching the site for a few hours I have been unable to find any kernel compatible with my stock rom version 5.0.1 and phone t-mobile us 851. Is there one available and if not is there any way I can overclock my phone without installing a custom rom and a kernel over it. I really appreciate any answers. Thank you. Also just wanted to mention that before asking I actually tried installing incompatible kernels pretty much knowing that they wouldn't work (thank goodness I backed up lol).

Using a pre-built MTK6589/8389 kernel in a custom (Lollipop) ROM

I've got an old Lenovo S6000 which, like every other Mediatek device, has incomplete source code for the drivers and the kernel. As a small project, I would like to try and get Android Lollipop up and running to an extent where:

• the system boots to the GUI;


• the Wi-Fi works;


• and the touchscreen works.

just to start off.

The device currently is rooted, with ClockworkMod recovery installed, and I can create Android back-ups of the system. Could I potentially take the kernel and the proprietary blobs and build them in to a CyanogenMod 12 update? Or would the kernel have to be patched to support the new features in Lollipop (the current OS running on the device is Android 4.2.2, and there have been no other working attempts to create a custom ROM for the device)?

Thanks,
George

[Q][Idea] N9006 needs original flashable kernel

I got N9006 from chine which has WCDMA and Snapdragon.
I'm using "[5.0.1][Note 4 Full port][01.09.2015]AuroraRom Note 4 V6 English" (from wellaflex). It got N9006 kernel in its package so i can install it to my phone but i want to test more roms and many of them dont have n9006 kernel. Is there a way to extract N9006 kernel from this rom or original package?

[Q]Which Custom ROM & Kernel You are waiting For Your Note 5?

I just got a Galaxy Note 5.Previously i owned a Note 4 which i think one of the most powerful phone of last year.One thing i don't like about Samsung phones is TouchWiz.So i installed CyanogenMod.The other ROM i installed is LolliFamous.
As now i have a note 5 i am waiting for these two ROMS.So guys which ROM and Kernel you are waiting for your Note 5?

CM11 kernel

Hello everyone! Because i was tired of lollipop performance and bugs on our phone, i decided to downgrade to cm11. I found this rom: http://forum.xda-developers.com/moto...od-11-t3216484 . But i cannot find a compatible kernel for it without losing wifi, so i have to deal with the screen flickering and subpar cpu management of the stock kernel. Can someone help me finding a kernel or making the newer ones work with wifi?

Extreme lag issues Xperia Pro (Lupus kernel + Ultimate HD ROM)

Good day all,

I am a proud owner of an Xperia Pro... Or was. I have this phone since 2011 and in order to keep using it I had to perform some major enchangements to keep it going.

The enchangements:

- Lupus stock plus kernel ICS
- Ultimate HD ROM
- Greenify (paid version)
- Link2SD (paid verison) all user apps are on ext2
- I/O = 'SIO'
- Governor = 'LagFree'
- CPU = '1018mhz'

There is no bloatware (removed it with Titanium Backup) on this phone, except for Google Play Services (which Tinder intended me to have in order to make use of it)


Now the issues. The phone is horribly slow sometimes, and has its moments that it reboots itself when it gets just a little heavy. Like, during navigation per bluetooth on car the phone reboots itself sometimes without a clue. Underneath here is a general list of what is wrong with the average usage on daily bases:

- Whatsapp sometimes takes avg 12 seconds to start
- Tinder takes avg 10 sec to start
- Browser (Dolphin) most times takes avg 5 seconds before I can use it.
- RootExplorer takes avg 5 seconds before I can use it.
- Quickpic takes 5 seconds before thumbnails are loaded

Please know that this is not always the issue, but most of the times: it is.
With several software I have tried to find the reason for this ridiculous lag, but I always seem to have enough RAM, internal memory and enough CPU so I don't know what is going on.
I also turned on the options to show ANR's in the background, it usually tells me either Whatsapp or Google Play that became an ANR, sometimes as a follow-up it says SystemUI ANR too.

I can re-flash the ROM and kernel but within a few days I will experience the same sh*t again.

Any other Xperia Pro user experience this? What are my options?

NOTE: I prefer not buying a new phone, in the Netherlands there are no such phones like the Xperia Pro anymore because of fashion reasons.

[Q] How do I properly use a prebuilt kernel with AOSP?

I'm trying to build AOSP for Moto X 2013 (ghost). I've successfully built the kernel separately already (and flashed it to my device to make sure it works) but I can't seem to find a way to tell AOSP to use it. I get the following error when running make -j16 otapackage:
No private recovery resources for TARGET_DEVICE ghost
make: *** No rule to make target `out/target/product/ghost/kernel', needed by `out/target/product/ghost/boot.img'. Stop.

I've already tried to add this line to device.mk:
LOCAL_KERNEL := device/motorola/ghost-kernel/zImage
But it did nothing.

Any ideas?

Custom kernel

Hello,

Are there any custom kernels available for the honor 7? My stock kernel is draining my battery, so I'd love a custom kernel.

Tab 4 (SM-T530NU) 4.4.2 = used ODIN & Flashed Kernel 2 Root w/ Towelroot; Flash back?

I have a Samsung Galaxy Tab 4 10.1 (SM-T530NU) Even though I'm running on 4.4.2., I wasn't able to ROOT using Towelroot.APK B/C the Kernel is A0A2. So, following the directions on a website (posted at the bottom of this post) I found my device's Model_ROOT.Kernel.Tar.md5 and it's Model_Kernel.Tar.md5 files the webpage stated I needed in order to ROOT my device via ODIN.

Using ODIN, I was successful in flashing the downloaded ROOT.Kernel.tar.md5 file. After completing the next step I was able to successfully gain ROOT privileges by opening TowelRoot.apk & clicking "Make it Rain"
I used a random Root Checker app I downloaded from the Google Play Store to verify whether or not Towelroot succeeded in ROOTING my device.

YEAH!! I HAVE SUPER USER PERMISSIONS!!

I was so excited to have ROOT access after several days of continuous research that I never proceeded to the final steps on the aforementioned website's tutorial. I didn't use Model.Kernel.tar.md5 to flash my device back. Know it's been 2-3 days since I ROOTED my Tab 4 & to the best of my knowledge, I haven't experienced too many relative issues other than both Lucky Patcher & Freedom apps have been unsuccessful when I attempt to get free In-App Purchases from other Apps & Games. Normally I would just uninstall both apps and shrug 'em off as being incompatible with my device but within the past 8-10 months, I've used both of these apps on 2 of my previously ROOTED devices & they both worked correctly from the start. Not to mention that one of those happened to be another Tab 4 which was the same Make & Model of the Tab 4 10.1 SM-T530NU I'm currently using & writing about - the only differences between the two is their SEstatus & their Kernels: Old Tab4 had Permissive SEstatus & the Kernel ended in AND1 while this new one is set to Enforcing SEstatus and it's Kernel ends in A0A2)

I have a few questions related to the information you just read in this Thread:

* Did I really f**k up when I 4got to Flash back after Rooting w/ Towelroot? (If so, what steps do I take)
* How do I get L.P. & Freedom.apk to work correctly? (Does having 'Enforcing' SE Linux Status an issue? Either way, I would like to know how I can switch my SEstatus to 'Permissive')
* How can I Factory Reset my Tab4 running on Kitkat 4.4.2 without losing ROOT access?)

Any Custom ( Oveclcockable ) Kernel?

Hi I was just wondering if any body knows if there is a kernel for the Z3TC for overclocking like the Z3. I would like to overclock my Z3TC LTE.:D

Installed a custom kernel and now cannot get into boot.

I had recently installed the kernel Amplitude 4.2 for AOSP 5.1 devices and my GS5 W8 model was running Lollipop 5.1.1 w/CM12.1 with Xposed modules. The phone boots into the GS5 screen it says the Yellow text at the top (Warranty Bit: kernel) and then immediately shuts down and reboots. It is not recognized by my computer and I cannot get into recovery or download mode. Is there any way to revert changes to the kernel???


Please Help.
