[Completed] [Q] how to extract kernel from rom.zip to flash seperately? - XDA Assist

i installed a custom kernel on custom rom without nandroid backup and now i want the ROM's own kernel as it was better optimized after analysis, so how do i extract it from the rom.zip file on my pc? and then flash it seperately through recovery like i flashed the custom kernel?
also, i was thinking about making a backup now with the new kernal and then flash the whole rom again with the stock kernel included and restore the backup but without the new kernal, but i dont seem to find an option in my recovery for such a custom restore, where do i deselect kernel restore? like i can in a stock firmaware's ftf file through flashtool. is it possible??
side note, (but could be related) can i use 2 different kernel management apps? one for overclocking and wide range of governors and the other for various kernal tweaks?? it could be what is causing the incompatibility in the fist place i think.... too much battery drain and touch screen goes crazy or unresponsive and ghost clicks and stuff. any suggestions?

Hi,
First, I will inform you that XDA Assist is here to help members navigate the site, not for support. Reading the stickies at the top of the Assist section will fill you in better.
You've been shown your device section to ask questions in your last Assist thread, here...
http://forum.xda-developers.com/showthread.php?t=2939871
Quickly, just flashing your rom again without wiping anything first will restore it's kernel. And no, you can't nandroid backup or restore only the kernel. It's all of the system or nothing.
And using 2 different kernel tweaking apps is never a good idea.
Any further questions can go in your device section. ?
Good luck and thread closed.

default (stock) 2.3.3 g2x kernel.

Hello,
I tried looking everywhere for the stock (default) 2.3.3. kernel (i don't want to flash an entire rom) if anyone know where i can find a link ,i would be most thankful.
thank you.
Goes in Q&A section I think.

Did you do a backup of the rom before changing the kernel. It is contained in the boot.img in the backup. Just use one of the flashable zips that flash the kernel and replace the boot.img and wireless.ko files from an original nandroid with the one in the flashable zip (ones I looked at the boot.img as in the kernel subdirectory). wireless.ko goes in /system/lib/modules directory. Just use 7-zip and open archive. Delete the boot.img and paste in the one you want. Cloese out 7-zip and then you have a flashable zip with the stock kernel. I have attached the boot.img from the stock GB rom. Make sure you unzip the file and remove the boot.img. Do not try to flash this zip. It won't work.
I went ahead and made a flashable zip to restore the stock GB kernel. A big caveat here is that I have not tested it out myself as I am currently already rocking the stock kernel. If you are a brave soul you can try it out. Based on my experience it should work with no problems. If it does work please report back here and I will make a new thread in the development section. Many people have been looking for this, including myself. Once I venture out to another kernel to overclock, I wanted to have a way to restore to stock if I needed it. For now I am sticking with the stock kernel as I find the phone fast enough as it is.
Make sure you clear the Dalvik cache before rebooting or you might hang during boot or get a boot loop. The first boot will take several minutes due to Dalvik cache being rebuilt.

I will post a thread in the development section once somebody confirms it works. I am pretty confident it will work. Using the same method that is used to flash custom kernels, but I used the boot.img and wireless.ko from the stock GB rom flash.

Not sure if I done anything wrong but here are the steps that i did:
- clear cache
- clear Dalvik cache
- flashed the zip file
- reboot
All I got was a black screen. I waited for about 15 mins but still black screen.

Did you flash it over the stock GB 2.3.3 rom? This is the original kernel and ony compatible with the stock rom. If you are running another rom that would result in a black screen due to incompatibility issues.
I'm using Xboarder's Stock Tweaked OTA Gingerbread build v1.2.2. I don't have the original stock rom. (stupid me, i didn't backup the stock rom before flashed another rom )
Edit: I tried again and it works beautiful. Thank you.
Thank you.
thank you all for your help.

[Q] How do I change ROMS??

If I am using this forum improperly or asking too many questions on one thread that don't fit together, please inform me kindly.
Stock on 2.3.4 hboot 1.18 I rooted with revolutionary, and installed teamwin recovery. I am using the newest CM7 from the rootzwiki I believe. This is what I flashed anyway - update-cm-7.1.0-SelfKANG10-Sensation-signed.zip. Now I am 2.3.7 kernel ver 2.6.35.13_CyanogenMod+ [email protected] #1
ROM Manager app is now on my phone, but it says I need Clockwork recovery to use it. I also read through google and forums that just flashing between ROMs you have to have like same kernels and stuff like that, which I am very noob too.
I'm having Google framework FC issues and no GPS on CM7.
I think I want to switch from CM7 to this MIUI zip I got at MIUI.us - MIUI.us_pyramid_1.12.9.01_Eng_Deo_ZipA_Signed.zip
Which recovery SHOULD I be using? If clockwork is way to go, can I just go to my ROM manager app where it says, "flash Clockwork to this phone"?
If I want to change ROMs, what do I need and NOT need to backup? What exactly is "nandroid" back up, is it better than backup apps? Do I need to backup ROMs, and what exactly is that and what is proper way?
Do I have to wipe then restore everytime? Had some issues with this first time from stock sense to CM7, couldn't get Titanium or mybackup pro to restore my apps, and my contacts are quadrupled in size and organized oddly.
What is the best way to switch ROMs, flashing, ROM Manager, something else?
IF I wanted to run only one ROM for lets say 6 months, after I flash it, can I delete that zip from sd card, and phone will still work?
Suggest a ROM for me if you like also

I personally don't use ROM Manager but use ClockworkMod alot. There is a thread here on CWM 5.0.2.0 somewhere, if I remember I'll add it.
Kernels need to be Compatible with the ROM. This compatibility requitement is in terms of Kernel revision (i.e. old Kernel might not work with a newer ROM). More importantly though there are two basic typed of ROM on the Sensation, namely Sense and AOSP based ones. These two varieties have completely different Kernels so you will need one from that branch. For example Faux makes two Kernel types AOSP (e.g. for CM7 and MIUI) and all the Sense derivatives.
I'm having Google framework FC issues and no GPS on CM7.
I think I want to switch from CM7 to this MIUI zip I got at MIUI.us - MIUI.us_pyramid_1.12.9.01_Eng_Deo_ZipA_Signed.zip

The Nandroid backup performs a backup of the various phone partitions onto the SD-Card. This allows for a point in time backup and recovery of the phone.
ALWAYS do a Nandroid backup before playing with a new ROM or Kernel, JUST IN CASE **** happens.

Depends if you want a Sense or ASOP based phone.
Ok ill try to hit all the points for you. First you can use any recovery you like (cwm, twrp, 4ext) but Rom manager will only work with cwm. You can get to your recovery 2 ways, either hold the power button and select reboot then recovery (note some roms don't have this) second power off your phone completely and hold vol down and power until you get to hboot and select recovery (note fastboot must be turned off in settings). Personally I don't recommend using Rom manager to flash your roms go to the recovery itself.
Flashing roms: it is recommended to wipe data wipe cache and wipe dalvik cache (its sometimes found under advanced like in cwm) and when you get that part down it isn't always neccesary but wipe system partition... Never ever wipe anything else... Unless your cleaning your battery stats but let's stick to the basics.
If you are just flashing an update to a Rom sometimes you don't have to wipe anything (i.e. cm7 v9 flashing to cm7 v10) but anytime you change Rom bases always wipe. Especially if you are going from cm7 to a sense 3 Rom and also sense 3.5 and vice versa. Also there are several superwipe files from several devs. I suggest using one of these. All you do is flash it like a Rom in recovery. They automatically wipe for you.
Kernels are labeled with the base you need I.e cm7 or sense review the kernels threads for more info.
Next, if you haven't wiped and tried a couple Roms that explains the contact problems and GPS issues.
A nandroid put simply is just a backup of your current Rom. Go to backup in your recovery and backup your current Rom. Is saves every little bit of your current Rom. You need to do this in case something goes wrong or if you don't like the new one. Then you can simply restore it if you need to.
After you flash a Rom it is in your phones memory. You can delete it off your sdcard no problems, unless you want to flash it again at another time. You can also delete old nandroids if you need to just keep at least the last one you made. They are large sometimes.
I have used about every Rom here I suggest mikes hdrevolution or cdtdroids Roms if you don't want cm7 (which is often referred to as aosp) if you want to try another aosp Rom try hypersensation it works good too.
And you used this forum perfectly asking questions in the q&a good job some people don't get that.
Edit: he beat me to the answers while I was typing lol. Also I hate autocorrect had to clean up my post hope it didn't confuse you.

Ok, this forum is awesome, and I will defintely check out the other forums for kernels and other topics. I am understanding most of your replies, but as you see I get other questions from some answers lol. I did just wipe everything(data factory reset) again, and installed the MIUI and when I signed in my google on setup, all my apps started downloading from market and my contacts were all there in a little bit better fashion than before. Also, when I put CM7 that was my FIRST ROM and immediately after my FIRST time attempting and successfully doing a root s-off. Now MIUI makes my 2nd ROM. I'm sure if I hang around here enough I'll get the hang of it all and start to figure it all out better. I vultured around these forums for 4 months with a stock phone before I did anything, and my phone isn't bricked so I'm happy about that.
For some more detail try checking out the stickies in the development section there are some awesome guides and answers there too.

So what is this; kernels and themes?

Just got my first device rooted.
Now i have installed a ROM.
I feel awesome.
But then i read this
"With ROM Manager you can back up your existing ROM, flash new ROMs, and install custom themes or kernels. It features a long list of ROMs which is frequently updated and you can install ROMs to the SD card or OTA (over the air). If you want to unlock features like premium ROMs, update notifications, and automatic backups, then you’ll need to spring for the premium version."
So now i am trying to figure out what custome themes are and what custom kernels are compared to the Avatar ROM i installed.

Now let me put this simple. The ROM is the operating system of your device (OS). You know what a theme is. Its just changing the way things look can be your icons, interface shade/colour,etc. Its just visuals. And the next is kernel. Kernels are the thing which links your OS and hardware. Literally they are responsible for the way your phone behaves. Custom kernels has tweaks whicj can improve your device's performance, the battery drain, way your processor's I/O works.. It helps you to do things like over clock and under clock,etc. But it is risky as your manufacturer has made a stable kernel for your device and these custom kernels may be unstable. Sure thing you dont want to mess with em unless you know what you are doing. Now as you have choice to do things like changing ROMs and Kernels using Rom manager, i would recommend you to use CWM and flash zip files which has ROMs and Kernels made specifically for your device as this is more safe. But be sure to have a backup as installing something not meant for your device will brick it. Dont worry. Have a backup and also Odin with stock rom incase its really hard bricked. If it helped hit thanks button plz..

Awesome now i have a good hint of what each thing are.
Now this lead me to some more questions.
Since i have already rooted my device. I have installed Avatar ROM and tested some others...
But i never made any backups... Is it to late for that?
Is my best choice to download Titanium Backup and backup everything with that application?
You said something else about Odin, how to backup aswell with that?
What is CWM and how does it differ from Rom Manager?
When i install a ROM i download a zip file, put it on my device SD card
Boot the phone in and wipe data, wipe cache, wipe delvik (or whatever it is called) and last install the new .zp file.

CWM is clockword mod recovery. An advanced recovery which has more options than stock recovery. I guess you already has cwm. Probably it must be what you used to flash the Rom and clear cache. Now to Titanium backup, it backs up the whole phone, so do cwm. As we use CWM for our flashing and other things, cwm backups should be enough unless you got space on your sd to have many backup files. And if your phone is working perfectly right now then its never late to take a cwm backup as if you ever encounter a bootloop while tweaking, you can restore your phone. Sometimes even cwm fails to fix your phone. This is where Odin comes in handy. Odin is a pc software which can be used to flash the stock Rom of your device. You can search and find the Stock Rom for your device and region if you google. You can find how to flash using odin guides out there. Flashing stock rom via odin will remove every traces of ever tweaking your phone which includes rooting, flashing of custom roms and kernels,etc. Your device will be just like when you bought it. This is helpful when you want to take your phone to service centres as rooting and doing other stuffs will void your warranty. Hopes this helps...

I can tho not figure out how to know for sure if i have CWM or not. I have no apps called that.
And how do i do a CWM backup if i can start CWM some other way than using an app icon ?

CWM is a shell and not an app and it cannot be installed on android os so you cant access it through your Rom but you can run it whenever you need it but through stock recovery. CWM comes as a .zip file which should be selected from stock recovery or in other words flash it. It will open cwm recovery. And you can access advanced recovery options which stock recovery doesn support. Well search and download cwm for your device, place it sd card root(not inside any folder), run it using install update option on your stock recovery, it will open cwm which will be in yellow colour themed. Select backup and restore opt in it and select backup. That will take care of taking full backup of your device.

Perfect for me to quick understand what I am reading in threads and other sources.
I have now a CWM backup, Titan Backup and installed Odin and found my stock ROM to use if things goes to ****.

Well.. Thats good to hear. And there was none other than me. And anyway a small precaution, never interrupt while you are flashing through Odin coz it will hard brick your device which is literally R.I.P to your device.

HTC Sensation unable to overclock despite root and Revolution HD Rom

Dear all,
I've been reading on this forum for some time because I rooted an Ainol tablet an a Sony phone with help from here before. But now I am totally stuck with my newly acquired 2nd-hand HTC Sensation.
I successfully flashed the Revolution Rom HD 7.3 to the phone but even with OC Daemon (or any other CPU tweaker) I cannot go over 1188000 as the max value. No overclocking possible.
Phone specs:
* bootloader unlocked (this means 'rooted', right?)
* Hboot 1.27.0000 (Pyramid)
* Firmware 3.33.401.1 series.
* S-ON RL.
Further info is eMMC-boot, and it has fastboot on it.
Is it necessary to make the phone S-OFF in order to enjoy the overclocking benefits of the custom Rom?
If so, do I need to do a factory reset to stock ICS rom before I can do the S-OFF?
What is the best method for my specs to get to S-OFF?
I tried in various ways with the Revolution Rom on there, but I didn't manage to do it.
I saw this method ( http://forum.xda-developers.com/showthread.php?p=41244866 ) but I wonder if there isn't another way? I saw other methods for other Hboot numbers but not for Hboot 1.27 ... and if I do use this method, can I do it with the Revolution Rom installed?
I tried flashing various kernels not in the stock rom (some of which wouldn't flash and some of which caused the famous wi-fi error - luckily I did a Nandroid backup of my last known good configuration... had the wi-fi error twice already now). It seems also that i get some sort of 'image error' or something every time the phone goes into bootloader. I was unsure what to do with the radio file that came with the rom. I tried to flash that with CWM because I didn't know any other way, and maybe that was a mistake? I read that this may cause battery issues, and it does seem as if the battery drained fairly quickly especially while on 3g or WiFi despite black screen etc.
Please help.
PS I can provide screenshots if it helps.
Hi.
1. No, unlocked BL does not mean rooted, it's irrelative. But as you have a custom ROM installed after unlocking bootloader, you're rooted. Because custom ROMs are normally pre-rooted.
2. S-off is not required to have your CPU/GPU overclocked, but you have booted up your ROM, this means you have a flashed kernel. But I suspect something right now. Did you perform a full wipe (deleting all data on internal partitions, data, system, cache and boot)? I don't think you have done. Therefore, you might still have stock kernel, which is not overclockable. To flash a kernel without a computer, you must have gained s-off. Otherwise you may not flash any kernel flawlessly, unless you either get s-off or flash the boot.img of the kernel using fastboot commands (as you mentioned, I don't think you know it, do you?) Post a screenshot of your kernel info at about phone - software section.
SENT FROM WHATEVER IS NOT SOMETHING TO BE LOCKED AT, THE THING IS THAT IT IS SENT.

he can flash kernel without pc(if it is as a flashable zip file)
with 4ext recovery and smartflash enabled
edit: OP you can't flash radio while on S-ON and that file can be flashed only from bootloader
you were thinking that you flashed it
and about battery in fresh install don't judge it so quickly
give it 4-5 circle charges until it settles down
then see how it bahaves

Oops... I didn't remember that at all..
SENT FROM WHATEVER IS NOT SOMETHING TO BE LOCKED AT, THE THING IS THAT IT IS SENT.
Thank you to both posters so far.
I do not remember if I did a full wipe at the time.
I just remember it seemed to have fully installed...
Here is the kernel details:
3.0.16-g31a4fc7
[email protected]#1
SMP PREEMPT
This is displayed regardless of which kernel I flashed... even with faux, this is what it would show.
I thought that might be because all kernels mimic the stock kernel...
So can you confirm that this is the stock kernel?
If so, I will go ahead and wipe everything... and start from scratch.
BUT - if I do that and then restore my Nandroid backup - won't the stock kernel be back?
And can I then reflash with faux kernel or any other compatible kernel while keeping my OS configuration?
Extra info:
I have CWMrecovery on it and Fastboot.
The Revolution Rom contains 3 kernels to choose from.
Initially I probably chose stock, but then reflashed the whole thing, trying to change it to on of the other two available choices.
So if I did a complete wipe and factory reset, and then reflashed with one of the other two built-in kernels,
would it then be overclockable?
And what would happen if I then restored my Nandroid backup - would the kernel I chose with the new installation remain in place as the backup is merely the configuration?

And what would happen if I then restored my Nandroid backup - would the kernel I chose with the new installation remain in place as the backup is merely the configuration?

if you choose one of the other two kernels then you can overclock
when you are restoring a nandroid backup it restores everything(system,data,boot,cache etc)
so if did a nandroid with stock kernel then it will restore that kernel too
edit: i advise to use 4ext recovery for flashing roms and kernels since you are on S-ON

Ok, thank you very much for the insight. Yes, I believe the backup had stock kernel. Must have been...
3 more questions before I consider taking action:
1. How do I get 4ext on there now that I have CWM already?
2. Is there a way to backup my current setup and later restore it minus the kernel?
3. Since my phone runs real smooth as is right now and I don't play 3D games anyway - what noticeable benefits do I get from overclocking?

Disclaimer :I don't know much, everything I say could be wrong for all I know. But if It is I hope someone corrects me on it
1. http://androidforums.com/cdma-evo-3...lash-recovery-image-via-fastboot-sd-card.html
The file name for sensation should be PG58IMG.zip
2. Titanium backup
3. If you're getting the level of performance you already want, I don't think there will be any noticeable difference. Most roms come with cpu governor that will adjust the cpu speed depending on task, low cpu to intensive, overclocking increases the maximum allowed, some app will take advantage of this it will drain battery faster and since you don't require more juice why waste battery?

for restore yes you can do also an advanced restore from 4ext recovery except titanium backup
just go to backup/restore->advanced restore and choose data
but don't restore system partition if you are coming from different rom or different base because you will have many fc's
Thank you to you both.
PG58IMG.zip - this file is 4ext? I do have this file and remember trying to install it via WMrecovery, but unsuccessful. How do I install it?
So if I understand this right, with Titanium Backup or via a 4ext advanced restore I can backup my whole configaration (installed apps, frozen apps, startup apps, accounts, screen config) for a given Rom? ANd then I can wipe everything and reflash the Rom with the desired kernel and then restore this backup and everything goes?

since you are on S-ON forget any pg58img.zip file
in my previous post i gave you a link on how to install 4ext recovery
about restore absolutely yes but don't restore boot partition
note: another way to install 4ext is to install 4ext updater apk
open the apk
select the touch version if you want
it will download it and install it for you
done:good:

What exactly do you mean by "except Titanium Backup" ?
What are "fc's" ?
ANd what do you mean by "base" ? Kernel?

the ability for backup/restore exists in recovery not only in titanium backup app
that's what i mean by "except"
fc's->forceclose
it means when you are opening an app(especially a system app)it crashes immediately
by base i mean a different version of android of the same rom or a completely different rom
kernel is the brain between software and hardware

@rz86
Thanks for the steps and clarifications. Life got me away from the screen awhile but I've now successfully done what you recommended. Works a charm

[Completed] Custom rom flashing problem

My Phone is Ace 3 (GT-S7272) ROOTED
i tried to make a custom rom with kitchen so i make a little changes on the stock rom
- Add Root Permission
- DeOdex
- Delete some apps i don't use and replaced them with ones i prefer
Build the rom and trying to flash it in Recovery mode
Wipe cache partition
Wipe Dalvik cache
Then Installed zip from sdcard
Everything tell now goes right and he says succesfully installed
BUT when i boot my phone i found NO Changes happened
everything is the same as i didn't flash any thing + Root acces removed
Can any one just tell me what happened and how can i fix this ?
I believe your updater Script may be responsible.
But you might be better off posting in this thread. This is a Rom Cooking question per se and not necessarily device related.
