Question about flashing a rom (kernel...?)

ok, so i just rooted my One X (AT&T) running 2.20 using the unlock-bootloader method (only one out there, right? )
i want to flash the latest stable CM10 rom (named cm-10.0.0-evita.zip), but i hear all this stuff about flashing the kernel or the boot.img first before flashing the rom...? i've never rooted/flashed on HTC before, so forgive me if it seems noobish. what i have heard so far is to flash the boot.img from the rom i want to flash while in fastboot from my computer, then transfer the zip to my phone and flash the zip from TWRP. this is what i have picked up from hours of web-crawling, so please correct me if i am wrong
and *sigh* yes, i did use the search bar. i was unable to find any forums relating to my specific question. i did find one, however, under the quad-core tegra One X (the international version) and didn't want to risk bricking my phone because of differences between the AT&T and Int'l versions.

Well. I'm gonna first say you didn't search very hard as there are 100,000 threads asking this same questions. BUT I will be nice today.
Open the cm10.zip and extract the boot.img from it and place them both on your sd card. No need to rezip the rom, just leave it as is.
With your phone in fastboot, open a command prompt in your fastboot folder and type fastboot flash boot boot.img.
Boot into TWRP and flash the cm10.zip

ok, thanks so much
i figured there were forums for this already but i've been looking for a week and a half and gathering all the information i needed for this moment. sorry to waste your time if it did, and thanks for the generosity i really do appreciate it

Or use flashgui app.. Its in apps and themes.. Download cm10 and gapps from your phone. Open flashgui. Browse and find cm10. Select it and let the app flash it.. IMMEDIATELY after boot into twrp, flash entire rom, once successful immediately flash gapps. Boot system and profit

how to update to 4.4.x after this... New to android

First of all, I have been reading this forum for about two weeks and just registered in order to get some help as I do not want to break my one week old nexus 5.
From my reading, the updates can be done in quite different ways and because of that I want to be sure what I should do.
I started by:
- root the mobile with cf-auto root. It did everything for me, got the superuser icon automatically
- installed clockwork mod and I have the custom recovery. By the way, I made a backup with it but where was it written? I want to copy it to my pc.
- other than that, I have installed some root only apps like rom manager, greenify, root Explorer, etc. I supported those developers with purchase. Those guys deserve it.
Anyway, i am looking for the safe way to update to 4.4.1. I read some members saying they lost root after the update, others lost something else (I am referring to the thread on nexus 5 general forum).
Can you help me? What path shall I go? Thanks a lot.

To update you'll basically have to go back to stock in a way. By that I mean you can either flash the System.img file from the Factory Image and then update using the update files for 4.4.1 by flashing it in recovery (via Sideload) and then just root again. OR you can install an updated "Stock" 4.4.1 image from the development section and root that.

Hi, your backups are in /mnt/shell/emulated/clockworkmod/backup/
Copy to your PC with 'adb pull /mnt/shell/emulated/clockworkmod/backup'

i sense i am getting somewhere but how do i do that? i am new to this and been reading a lot but the first time all seems very vague. i need a little more help from you!
lets assume i want to just apply the 4.4.1 update (maybe this is the easiest way for now). how do i do it?
also, after the update succeds, i need to root again correct? what happens to all the apps i have right now with root permissions? do they stop working until i root again and give them root privileges again? can i use the cf auto root again?
also, i am on ART, i thought of letting you know since that can cause some problems updating(??)

If you want to apply the new update it all depends on your current setup. I gave you vague options because I don't know what you've done to your phone. If you've only rooted and not changed any of the files in system then it's easy to just flash the update with the recovery. You can download the update and then start recovery (look it up). Once in recovery start ADB sideload and connect to your PC (this assumes you already have working ADB, if not.... look it up ). To sideload you just need to adb sideload filename.zip. You can probably use WugFresh's Toolkit to also sideload but I generally don't use those so dunno what they do these days. Much easier to learn and understand what it does then do it yourself.
If you have a custom recovery you might just be able to flash the update with the recovery like you normally flash any zip in recovery.

You can just copy it, no need to use ADB but this is why it's good to know how to use ADB.

thanks for the reply. i am reading on the adb sideload right now... i already have the update zip inside the platform tools. however, in the command prompt, it says my device is unauthorized (i have both the usb debugging and unknown sources ticked). the nexus 5 is connected as MTP.
any clues?
about what i have done to my nexus, i applied the cf autoroot, installed clockwork mod... nothing much besides some play store apps..
as for this paragraph:
"If you have a custom recovery you might just be able to flash the update with the recovery like you normally flash any zip in recovery. "
i have never done it, hence all these questions!

You do it from Recovery. So just copy the file to the phone in some folder. You can't update the phone with it running. So reboot to CWM and then choose Install from ZIP then find the file on your storage and then choose update. That may or may not work as I said depending.

yes, i have been reading those topics and many others.. i managed to solve the adb device unauthorized anyway. just flashed the 4.4.1 zip file under clockwork mod recover.. android is upgrading at the moment. lets see if everything is work as it should.

No need to sideload adb bla bla..
copy the OTA zip into the phone, and just flash it in CWM (install file from internal storage).. 1 minute and done.
You'll get error status 7 at checking if you changed something in system (apart from rooting), else you shouldn't have any problem.

yes, everything is fine. 4.4.1 loaded fine without any errors. i have root checker and when i tested, it says i do not have proper root access. i also lost my clockwork mod recovery.
i am now checking into it to see what needs to be done to gain root access again and get the custom recovery as it was before the update.

You need to flash the recovery again via fastboot (youll lose it every time, unless you flash the flashable recovery ZIP just after flashing the OTA and before rebooting the phone).You'll have this problem every OTA unless you flash the zipped version everytime.
I'd recommend the easy way to root, get the SuperSU binaries and flash them through the custom recovery and you're done..

You'd only be looking for the supersu binaries, since you already have the recovery IMG from te previous time, right? (the one that you need for fastboot).

That's the stock recovery, you can't do nothing from there.
You need to flash the recovery via fastboot (didn't you do that the first time to get your custom recovery..?)

from where can i get the flashable clokwork mod recovery zip file?
i am going to apply the 4.4.2 update now and will be doing it this way:
from the recovery apply the 4.4.2 zip. after this apply the supersu zip. i want to install the custom recovery zip too so when the phone restarts everything will be configured. is this possible?

well, it seems i haven't lost my custom recovery. was it because i installed the supersu before rebooting?

[Q] how to reflesh stock kernel?

Ok so i flashed francos kernel trough FKU updater app and i want to go back to stock just to compare the battery life and some stuff again and to decide what to use.
How can i flash stock kernel back, do i flash all factory images or is there .zip file to flash trough recovery, or there is another way to do this? thanks for your replays.

boot.img is the kernel. If you have the factory images you can just fastboot flash that,

Last thing since you came from Franco kernel (the following procedure is specific):
The Gingerbread Man said:
Return to stock romz
Franco's kernel changes these system files below, so to change them back you can remove the .bak extension, or fastboot system.IMG and boot.IMG from a Google factory image which is probably easier and faster.
1 - Rename /system/lib/hw/power.msm8974.so.bak to /system/lib/hw/power.msm8974.so
2 - Rename /system/bin/thermal-engine-hh-bak to /system/bin/thermal-engine-hh
3 - Reboot to the boot loader and flash stock Kernel by downloading the Nexus images and then fastboot flash boot boot.img
...

So before flashing the stock kernel in recovery do the step 1 and 2 (even after if you forgot, it should be good).

With a file explorer, directly from your phone, (Root Explorer, Es File Explorer, etc...) follow the path to the files in point 1 and 2, rename the files and save. Then reboot in recovery and flash the stock kernel if you want to flash it via recovery (equal to step 3).
If you are not used with this kind of stuff (modify system files by yourself), flash the system.img and boot.img by following the link I provided above (http://forum.xda-developers.com/showthread.php?t=2513701).

im not used to this stuff yet because i rooted my phone yesterday and im quite new to this because last device i rooted and flashed lots of custom roms and stuff is to HD2 so i know the basic stuff but not much
and one of the topic question. why does my colors look a little diferent when i flashed the francos kernel? i know that there is something about color profiles etc. but i do not know where to start and look into that

I made a stock kernel backup on Franco app and used it to restore back to stock kernel after using Franco was this process ok
Sent from my Nexus 5 using xda app-developers app

Screen went blank after flashing boot.img

Meaning to install CyanogenMod I followed CyanogenMod wiki instructions (can't post link here)
Only that I have TWRP instead of CWM.
When I got to installing "CyanogenMod from recovery" I got a message saying that the pushing had failed because permissions did not allow it.
So I tried a solution they suggested for a similar message which did not work, and then I read the note at the bottom that says the kernel should be flashed via fastboot, I flashed it but now it's just blank (I guess because it has an alien kernel and the rest is the same)
I dont have a copy of my previous boot.img

What do you mean you couldn't do it on adb? Do what on adb? You don't use adb to flash a ROM.

I mean to push the rom on the root of the sdcard: look at the instructions I followed:
Place the CyanogenMod rom .zip file on the root of the SD card using adb:
Transfer your file(s): adb push YOURROMZIP.zip /sdcard/
If you boot directly to recovery and have an internal sdcard, you may need to run adb shell mount /sdcard or mount data through the recovery menu before transferring.
If you see "error: device not found" there is likely a driver issue on the PC.
If you see "error: insufficient permissions for device", try "adb kill-server" and then run "adb devices" to see if the device is attached.
On some devices, the zip file can be copied to the device using standard USB Mass Storage or MTP support. Boot the device normally and transfer the file to it.
Optional: Place any supplemental packages (e.g. Google Apps[1] or kernel) .zip file(s) on the root of the SD card.
Boot to recovery mode on the device by holding With the device powered down, hold the Volume Down and Power buttons until HBOOT appears, then release the buttons. Navigate using the volume keys and select RECOVERY using the Power key..
Once the device boots into the ClockworkMod Recovery, use the physical volume buttons to move up and down. On most devices, the power button is used to confirm your selection, although for some devices the power button is used as a "back" button to go up one level, in which case the home button is used to confirm the selection.
Optional/Recommended: Select backup and restore to create a backup of the current installation on the device. If this option is missing, it's likely because the stock ROM has overwritten your custom recovery on boot.
Select the option to wipe data/factory reset.
Select install zip from sdcard.
Select choose zip from sdcard.
Select the CyanogenMod file you placed on the sdcard. You will then need to then confirm that you do wish to flash this file.
Optional: Install any additional packages you wish using the same method.
Once the installation has finished, return back to the main menu, and select the reboot system now option. The device should now boot into CyanogenMod.

And the note I mentioned:
Note:
This device, if unlocked with HTC Dev Unlock, MUST have its kernel flashed via fastboot! Extract the boot.img from the rom zip and flash using fastboot flash boot boot.img

So you never actually flashed the ROM but you flashed the boot.img from the ROM zip anyway? No wonder it isn't working, you've flashed an incompatible boot.img onto whatever ROM you previously had installed (which is still installed by the way because flashing a boot.img does not flash a ROM).
All you needed to do was mount your sd card using TWRP (menu/mount/mount usb storage) and copy the ROM zip across, then install it. You have s-off so you don't ever need to flash the boot.img separately.
I really think you need to do some research, it seems you lack even a basic understanding of what you're doing. You don't know what a boot.img is or what it does or how or why you would need to flash it. You don't seem to know how to use your custom recovery. You don't seem to know how to install a ROM.
A lack of knowledge is almost always what leads to somebody bricking their phone, which I'm sure you don't want to happen. Do yourself a favour and spend the next couple of days reading up so you have a better understanding of modified devices. A great place to start would be my Evita FAQ thread and my How-To Guide For Beginners thread, you'll find both in my signature.

I'm not sure where you found that note but it isn't entirely correct. Only Evitas with s-on and a hboot greater than 1.09 need to flash the boot.img via fastboot.

This is where it's from
wiki cyanogenmod org / w / Install_CM_for_evita
I'm sorry for having hurried and done that but I couldn't flash the ROM and there were no more instructions, I've been reading for the last months, and even though I thought replacing the kernel could not be the best idea, it was the only idea I could get from those instructions and I thought maybe the kernel would have to be moved first for some reason. Anyway, thank you very much for your patience, I have to do it today because I have to travel and at&t limitations on the network -since it forces 4G- won't allow me to use my current carrier. I tried just moving the ROM by mounting and it worked. Thanks man

[5.0] Nexus 5 Refuses To Flash OTA or Different ROM's

Hello,
So I just discovered this while trying to flash the 5.0.1 OTA from 5.0. I'm rooted on LRX21O via the Nexus Root Toolkit 1.9.9 (which is what I've always used in the past with no issues).
1 Tried flashing the OTA via Google notification push. It reboot, and no changes occur.
2 Fine - I try to use the Root Toolkit again. Boots into bootloader, appears to flash the radio and other necessary components. Reboots - no changes occur.
3 I then tried to just download the 5.0.1 package and flash everything manually via adb. Everything appears to go smoothly, and upon bootup Android updates all of its apps - still nothing. I appear to be completely stuck on LRX21O without any way to reflash stock or OTA's.
Anyone have any clue why this is occurring or have heard of such an issue before?
Thanks all.

Just flash factory images. With fastboot/flash-all script.

You flash these in fastboot not adb

Did you not understand? I did flash in boot loader USING adb on my computer. All that bat script does is just automate the flashing of each image for you (system, radio, etc) so this is not helpful. I know how to flash, but flashing seems to have no effect despite successfully flashing via manually installing or just using the script

You use fastboot in bootloader, not adb.

I'm not the one asking for help. Anyways, carry on.

Your device's /system partition is tampered (you say you rooted it) and thus the OTA fails. Flash the 5.0 factory image (LRX21O) WITHOUT rooting/flashing kernels/whatever and then use the OTA zip to do adb sideload in the stock recovery to update to 5.0.1 LRX22C.

Manually use fastboot commands to flash system.img and boot.img of the full 5.0.1 factory image (not script). post the output please

I'm not the one asking for help. Anyways, carry on.

Sorry about that - didn't mean to come across snippy
It worked this time with fastboot. For future reference can this be done the same way with the OTA update zip instead of reflashing the entire image?

No, but if your phone is setup correctly you can sideload the ota zip in the stock recovery

Would you mind explaining this? I've used sideload in cwm and twrp before but I'm unsure of how to operate anything within stock recovery. adb won't even connect while in recovery. I would like to just remain on unrooted stock until xposed eventually get's developed for ART and flash zips that way.

Sideloading in the stock recovery works much the same as in a custom recovery. Boot into the stock recovery and there is an option to sideload. Then on your pc in a command window you type adb sideload update.zip. or whatever the file name is that you're trying to sideload. Obviously, if you can't get adb to recognize your device that's a problem. But that's a separate driver issue.

How can this be possible though without a custom recovery with the sideload feature? Stock recovery is essentially unusable as it just displays a picture of a dead android on a black screen.
Perhaps we're on different pages, or am I just confused still?

sideloading an OTA update from stock recovery
Hello, to make it work you will need to use the Google USB drivers you downloaded when you go into stock recovery then press the power button and volume up once then you will see a menu option with the "install update from adb option select this and plug in your phone to the computer. After this is done you will need to go to device manager and install the USB drivers from the Google USB drivers you downloaded. at this point after that is done you then go into the folder that has ADB installed and use adb sideload filename.zip
at this point your phone will accept the ota update package and you wont lose any data, I hope this helps..

When you get the dead android you need to press vol up and then press and release power. That'll get you into the stock recovery. It's stupid and I don't know why they made it that way

thanks all, can't believe i never knew that volumeup+power got me into stock recovery options.
new issue: sideload works all well and perfect, but how can I bypass the "signature verification failed" flag that kicks me from the zip install every time?

Well you can't. The limitation of the stock recovery is you can only flash files signed by Google. That's why you need a custom recovery to flash most files

So can I just flash twrp with fastboot and go about that method? I believe it can bypass the signature. I am unlocked without root currently.

If you're trying to flash the update.zip to 5.0.1 you need to do that in the stock recovery. It will not work in twrp or cwm. I'm not sure what you're trying to do right now
Sent from my Nexus 9 using XDA Free mobile app

my apologies.
so originally i wanted to just flash the OTA. ended up performing a fresh install and un-rooted. but there's a few unsigned zips i like to have installed.
So I think I'm going to re-root, flash twrp, install my zips, and leave it at that. i'll just flash stock recovery whenever I need the OTA which should be quick now that I know what to do.
hope that sounds correct. thanks for all the help!
