[Q] New to modding, easiest way to install Kernel?

Hey guys, getting my Nexus 4 for Christmas and looking to install Franco Kernel.
I was wondering the best way to install it, I have searched for tuts but nothing is clear. I know he has an app for his kernel, does this require root to use? It doesn't mention it.
Any help would be greatly appreciated.

Go here and download the All In One script: http://forum.xda-developers.com/showthread.php?t=1995688
You're going to need to unlock the bootloader (will wipe your phone), so follow the steps in doing that.
Next, you'll need the latest CWM Recovery: http://forum.xda-developers.com/showthread.php?t=1995440
Follow those steps. Then download the Franco kernel .zip from its appropriate thread and flash it in CWM.

First thing I'm going to tell you - Go back and read the OP. Because he actually does have instructions in it (Although very minimal).
http://forum.xda-developers.com/showpost.php?p=34375927&postcount=1
Here's the quick and simple of how to do it.
1. Download the Nexus 4 Toolkit -- http://forum.xda-developers.com/showthread.php?t=1995688 (READ THE OP COMPLETELY)
2. Unlock the bootloader.
3. Install custom recovery.
4. TAKE A BACKUP!
5. Transfer kernel files to device.
6. Use recovery to flash files.
7. Hold breath while booting.

DO NOT USE TOOLKITS. Especially if you're new to modding.
That's like saying, I want to overclockmy computer. Just give me a toolkit where I can one click and overclock my computer.

Do it the proper way and download ADB drivers
http://forum.xda-developers.com/showthread.php?t=1514942 (enable USB debugging)
set up ADB environment
adb reboot bootloader
fastboot oem unlock
unlock bootloader on phone
download clockwork recovery or TWRP (i suggest TWRP)
put the .img file of recovery into your /platform-tools/
fastboot flash recovery <name-of-file>.img
then boot into recovery and there you can flash your ROM, gapps, kernel.
In the long run, IT WILL PAY OFF because eventually YOU will be faced with a problem with your phone and you won't be able to recover your phone because you dont know basic fastboot or adb commands all simply because you wanted to use a toolkit. People are already asking on how to use adb / fastboot in Q&A, we can reduce the clutter by not having people use toolkits and actually learning how adb / fastboot works when it isn't a very complicated thing to do at all

Make sure the boot partition is checked when you are backing up. To return to the stock kernel, (if you ever need to) you will need to restore this backed up boot image.

no you need custom recovery

Unlock the bootloader, install a custom recovery and flash the zip.

root 4.2.2. without flashing customer recovery

Good morning guys,
I see a lot of threads here about rooting 4.2.2, but in all of them it is recommended to root the phone by installing zip archive from a custom recovery.
I don't want to change stock recovery - is there any way to root it by flashing img from adb? I did it in this way on 4.2.1, by installing CF-Auto-Root-mako-occam-nexus4.img file from adb.
Can anyone advice how to get root without flashing custom recovery?

I have to ask,....why would you NOT want a custom recovery? What is the point in using a crippled stick recovery?
From my Evo LTE, yup.

Look at this How to thread in the general section, I copied and pasted relevant information. I kept a custom recovery and didn't try this method, but it says it will not flash a custom recovery.
E. Optional -- Root
If you want to get root access follow the steps below. (And no, this will not flash a custom recovery, and not, it will not make you "not stock".) Unlocked bootloader required. See steps above.
1) Download (to your computer) the latest version of CWM (from here) or TWRP (from here) for your device;
2) Rename the file to customrecovery.img, and make sure it is in the same directory as your fastboot.exe file;
3) Download (to /sdcard on your device) the latest version of either ChainsDD's Superuser (not currently working), or Chainfire's SuperSU;
4) Restart your device in fastboot mode and plug into computer;
5) Open a command prompt in the directory mentioned above and type: fastboot boot customrecovery.img
6) Wait for it to boot;
7) Navigate the menus the recovery menu on your device and select an option like "update zip from sdcard". Find the zip that you downloaded, and apply it.
8) Reboot. Done.

You can flash custom recovery via fastboot, use it to install su.zip and when you will choose restart after that, you will have question about you want custom recovery permanently or not, if you choose no then after restart you will have stock recovery

I want to make installing of future OTA as simple as possible. So I will get root and freeze all the system apps i don't want to be run, but when OTA comes I will be able to install it and will not receive any error messages which i had during this OTA.
It seems like this is a good solution:
5) Open a command prompt in the directory mentioned above and type: fastboot boot customrecovery.img

Do i understand correctly that this boots customer recovery on my phone from PC hard drive, but doesn't flash it to the phone? So, I'm able to install root.zip from it, but when i reboot the phone I don't have a custom recovery.

You can do as i mentioned in my post before or you can use as well command mentioned by ketjr81: fastboot boot nameofrecovery.img in both cases you will have had stock recovery after restart

Thank you guys, you have solved my issue. Now i have to find a ZIP with root to flash.

Will search you find says Yoda

Download ROM Manager. It'll install CWM for you.
Fwiw, most people seem to prefer TWRP, but it's your choice... :thumbup:

Download CWM Touch for Nexus 7 from http://www.clockworkmod.com/rommanage
Save it to computer.
Then boot Nexus 7 into bootloader, plug device into computer and use fastboot to flash the recovery IMG.

Hi, superuser.pm....
There's more than one way of skinning a cat!
There are several different ways of changing from TWRP to CWM.
ROM Manager should do it, and it should be the easiest. But I haven't used it for quite a while, so I really can't comment on it.
Alternatively, you could download the the CWM .img file directly to your PC... from here:
http://www.clockworkmod.com/rommanager.
Make sure you get the right version for your device. Ideally, you want the 'touch recovery' version.
Rename it to 'recovery.img'...
And then fastboot flash it with....(with the Nexus 7 booted into the Bootloader).
Code:
fastboot flash recovery recovery.img
----- OR -----
(YOU WILL ALREADY NEED TO BE ROOTED FOR THE FOLLOWING TO WORK. If you need a Recovery to initially acquire Root... then you'll need to use fastboot).
Download the CWM .img file (from the same link, as above) directly to your Nexus 7 (it's not big, around 6.6Mb, should download to the /download folder)...
And then use either of these two apps to flash...
Flash Image GUI or...
Flashify
---------
Flashify, I think is the better of the two, but the free version has a limit of 3 flashes per day (although I can't imagine why you'd want to perform more than 3 .img flashes in any given day).
In any case, either of these will 'write' a recovery .img to the recovery partition - and that includes either CWM or TWRP .img files. Just follow the on-screen instructions. Both apps will request Root access.
I prefer this method over fastboot... not because I don't like fastboot, but because I can easily flash a recovery (performed entirely on my Nexus7) without having to drag out my Windoze laptop (and avoiding dealing with Windoze is always a desirable goal IMHO!)

[Guide] How to install a custom recovery and root

OK, I see that this subject has not been properly addressed in this forum and there are a lot of users who still use tool kits,etc. for this. That's fine but you're missing out on how to more effectively manage your device. I'm writing this off the top of my head, and on my n9 which is not so easy, so I may modify it in the future.
The first thing you want to do is learn how to use fastboot. Fastboot allows you to flash image, .img, files on your device. If you've never done that start here, http://forum.xda-developers.com/nexus-9/general/guide-how-to-unlock-bootloader-flash-t3035153
Rooting is as simple as flashing a custom recovery on your device and then booting into that recovery and flashing Chainfires supersu.
So how do you flash a custom recovery? Well I strongly recommend twrp. Download the latest from here, https://dl.twrp.me/flounder/ I always find it easier to rename the file you download to simply recovery. Make sure you maintain the .img file extension. Download this onto your pc and remember what folder you downloaded it to.
Then download the supersu.zip file to your device. Download from here, https://download.chainfire.eu/696/SuperSU
Now you're ready to get started. Boot your device into the bootloader and connect it to your pc.
On your computer open the folder where you downloaded the twrp image. On an open area in that folder shift, right click on your mouse. You should see a pop up and a place to "open a command window here" In that command window type, fastboot devices. If you see your device's serial number you're good to go to flash the twrp image file.
OK, the Nexus 9 is not as easy to root as other Nexus devices. So start by typing, fastboot boot recovery.img. (Remember I told you to rename the twrp image file to recovery, if you didn't do that use the full name of the twrp file you downloaded for recovery.img) Once you boot into twrp go to install and find the supersu.zip you downloaded onto your device. Install it.
Then from twrp, boot back into the bootloader.
Once booted into the bootloader open a command window in the same folder as you have the twrp image downloaded. Then type fastboot flash recovery recovery.img
You're now rooted and have twrp installed.

Having major problems trying to do this on Marshmallow, lol.

This no longer works as described on 6.0. I can get you rooted but I can't get twrp to work properly. It doesn't decrypt the device. But you'll need a usb stick.
To the usb stick copy flar2's elemental x kernel, http://forum.xda-developers.com/nexus-9/orig-development/kernel-elementalx-n9-0-02-alpha-t2931657. Also copy supersu, http://forum.xda-developers.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133
Boot into twrp:
fastboot boot twrp.img. Use twrp 2.8.7.0 and the full name of the image file
When you boot into twrp hit cancel. It'll boot into twrp but won't decrypt your device. In twrp go to mount and mount your usb stick. Then from twrp flash the elemental x kernel. Then flash supersu.

If you don't have USB stick, adb sideload worked for me to flash supersu beta 2.5.1

No, you need a usb stick and adapter to the device. But what mrRobinson said should work too. You can do that from your pc.

Thanks, that worked.
I went and installed Busybox, not sure if I needed to?
I really want to get this thing decrypted now but am happy to wait for a Marshmallow solution rather than go back. I suppose I could flash a ROM without forced encryption from the flash drive too? As long as I do a full wipe?
I only got my N9 a week ago and haven't had time to play with it so all this encryption stuff is new to me.
---------- Post added at 09:08 PM ---------- Previous post was at 09:04 PM ----------
I am rooted but can;t copy hosts file over, system is read-only, is this an encryption thing or has something gone wrong please?
---------- Post added at 09:28 PM ---------- Previous post was at 09:08 PM ----------
One more question..
If I was to factory reset and then flash the kernel and supersu would I get an unencrypted device? Or if I hit the "decrypt data" button in the "wipe" menu in TWRP? I am scared to press it, lol.

Excuse me but this only adds confusion in case of 6.0. So far the most comprehensive guide I found here is this one (see also an answer there).
That solution involves wiping data, so you need your stuff backed up somewhere. In my case I restored playstore apps from google account and just reinstalled the rest from apks.

I answered my own questions here http://forum.xda-developers.com/nexus-9/help/decrypt-marshmallow-question-t3222592. Thanks again for the help jd1639.

worked like a charm :good:

Any difference when already running 7.0?

I keep getting stuck in a bootloop after flashing SuperSu. Any thoughts on this? I've tried wiping caches/dalvik. Running latest stock version of 6, latest version of TWRP, installed proper ElementalX for Android version, boots fine after the kernel install.

For N (and MM in some cases), you need systemless support - which the current version of SuperSU has. (Magisk 12.0 has it as well.)
Where Magisk (vice SuperSU) has advantages is being able to hide that you're rooted (Android/Samsung Pay, Visa Checkout, SafetyNet, etc.) - which is, in fact, why I am evaluating Magisk.
So far, I have seen next to no disadvantages to N - even on "moldy" SoCs (such as the TI OMAP in my Galaxy Nexus - the oldest hardware I've heard of - let alone seen - running N on a daily basis; I run N as a daily driver). I even prefer N to MM, let alone anything older, on the selfsame GNex (which utterly flies in the face of "common wisdom"; it makes me wonder, in fact, if "common wisdom" is a coverup for "fear of change", since said "common wisdom" predates Android by several years).

Hi,
Isn't is required to unlock bootloader first ?
Where this unlocking is done in this procedure ?

That is always the first step and doesn't change. This thread covers the changing root methods on different Android versions.

Thanks,
Yet, I noticed in many threads of rooting in mediatek devices, that just flashing recovery.img and boot.img is the 1st procedure to make the device root.
Does it mean that mediatek device does not require unlocking the bootloader ?
Thx

J700P Utilities

Here are some utilties for customizing your J700P. Please note I do not own and I have not created any of these, that honor goes to the original creators. This was all put in one place by @DirtyPISTOLA.
LINK
If you do not wish to have TWRP, but wish to have root, download the CF-Auto-Root file, then download Odin. Make sure you have OEM Unlock enabled in dev settings, then boot into download mode and flash the file using Odin.
If you don't know how to flash with Odin, again, you must have OEM Unlock enabled. You would then plug in your phone booted into download mode, and click the AP tab in Odin. Then, you select the file to flash.
This also has Xposed for our device, which you can flash using flashfire on an already rooted device. If you wish to root using TWRP, follow my guide here.
It also has a boot img with adb root access and system root if you want that as well.
There is stock boot and stock recovery + stock firmware if you mess up.
This is pretty much the ultimate resource for customizing your J700P model J7. Have fun!
