Flashing new Froyo Kernels - Desire General

Hello,
Can anyone tell me if it is possible to get back to the original kernel, without the Noecho mod installed on it?
And whether you need to wipe phone to install new kernels, or if they are just like ordinary kernel upgrades/ downgrades?
Thanks

SetCPU = Neurotic with stock rooted 2.2

I know you need to do perf unlock now, but even when I do that setCPU still has shows the processor as fluxing all over the place. I had to uninstall it.
Guess I'll have to install a custom kernel.
Is anyone else having these problems?
If I install a custom kernel, will flashing a nandroid backup of what I had before hand get me back to before I flashed? Or are kernels more permanent than, say flashing a ROM? Do i need to wipe anything before flashing the kernel?
If you nandroid it will save your kernel. I recommend nandroiding then wiping cache/dalvik and flashing the kernel. then if you want to go back you can just restore. For the most part flashing a kernel should not mess up anything that would require you to re-setup your whole phone. it should be pretty painless.
If you can find a separate zips for the original kernels it is very much like flashing a rom. I am not sure if it will fix your problem but i do know i haven't had that problem using netarchy's kernel (as long as you dotn mind the 3MP back camera)

[Q] Bananacakes kernel on InsertCoin ROM?

Hi all,
Has anyone tried the new bananacakes kernel 0.4 based on the official kernel source?
I tried installing it but my phone randomly resets every now and then. I've gone back to a Nandroid backup for now but I'd really like to use the new kernel.
Can someone who has successfully updated their InsertCoin ROM with the new kernel post some tips?
Thanks.
TBH, if you have problems with a kernel or any other file you flash or install, you're better off not using it anyway. Just "suffer" with what you've got.
You could always try a different ROM with a kernel (if compatible) or try a different kernel with the existing ROM.
Have you tried reflashing/installing the ROM and kernel from new after full wipe? Sometimes you can get issues with a file and undoing then re-flashing/installing can sort this most of the time (providing the file is stable). Are there any instability notes with the ROM/kernel? If so you may want to wait until stable versions are posted.
I updated the kernel without doing a full wipe, didn't want to lose all my settings.
Oh well, I'll do a full wipe and give it a try.
Thanks.

Problem with flashing custom rom

Ive got this message in cwm when was restoring (jj's hybrid for locked bootloader): no app2sd partition found, any ideas?
Locked Bootloader Arc S.
When i want to format sd-ext --> same message.

Bump

That means that CWM didn't find a second partition in your SD card used by Link2SD.
Is it working fine, JJ ROM?
Im just wondering if i can flash it with this 'error'.
Prince
I presume jj's rom has app2ext built in, but it shouldn't affect the rom. But check on the rom thread.

I was asking, but no1 replied.
Prince
It will work. That "error" is just a check if a sd partition exists to make use of. Wont affect sysyem if missing.

hints that migh be helpful to prevent trouble when flashing custom roms & kernels
hi there,
i'm not entirely sure if this will help you but generally speaking i came made a few observations about the fact that some people, mostly repeatingly the same users, encounter problems with their custom roms and/or flashing them, while others don't, albeit they are using the same devices.
i myself use 3 different devices, all rooted and running on pac 4.3, always latest nightly, as there are GT-N7100 - GT-I9100 - Nexus 4
not to the point
a) other than most other users i usually clean cache and dalvik cache as well before and after flashing the new rom and/or new nightly
and never encountrer any problems except those which everybody, using the same rom and nightly encounters.
b) whenever i flash an totally different rom and/or upgrade and/or downgrade to another level of android os, i.e. from 4.2.2 to 4.3, i perform
a clean install, including not only a factory reset, but as well a format sd-card, format cache and format system etc., again i cannot proof
which of these steps make a or the differnce but however, i never have problems others than thosw which everyone has with a version.
c) when using cusome kernels and due to the fact that some roms come with a kernel included, as well as with a custom recovery included,
it is strongly recommended not to forget to flas the kernel again after each flashing the new rom. one good example ist dorimanx kernel
for GT-I9100 which will not boot into recovery and reluctantly boot at all after a new flash of a pac nightly without reflashing the kernel.
d) try to fix permissions on reboot instead of doing it from recovery. one reason is that not every recovery has this option and further i
found that when fixing permissions before the first boot after flashing a new rom, there might be bootloops, albeit i cannot explain exactly
why that should, but however, sometimes it's better to be on the safe sid.
e) try to run whether the lastes version of custom recovery for your device, and or the use the included custom recovery of the rom or the
kernel. this again is one thing that can help to avoid some unexpected and hard to explain bootproblems and/or fc's etc.
hope that i could give you some new ideas how to avoid trouble while using custom roms and other hacks

You must use ICS kernel, either unlock bootloader and install custom ICS kernel, or first install/update to stock ICS and then follow the same method.
i already did 6 times
i already tried 6-7 time to install custom rom when it stuck on sony logo i flashed it with orignal stock rom and tried again but every times same problem arise. now i am not understanding where i missed

First install stock ICS firmware, Android 4.0.4 (4.1.B.0.587 or 4.1.B.0.431), and then install the custom ROM. Did you do it so? Can you write the file, which you used?
no..i flashed only base version 4.0.2.A
i always flash "LT18i_4.0.2.A.0.58(2.3.4)_HK" after every bootloop, i not tried to flash 4.1.B.587....few month before tried it to flash but i think it is not able to flash because of system partition is is less because of 4.0.2.................well benifit of installing upgraded rom "4.0.4 (4.1.B.0.587 or 4.1.B.0.431)" and are you sure after that i will able to install it..?

[Q] Kernels and restoring a nandroid backup

After flashing a kernel, they say to do a full wipe (and then reinstall the ROM?).
My question is whether after the wipe, can I restore a nandroid backup? Setting it up from scratch and just the way I like it is quite tedious if I were to do this each time, plus download the apps from the market etc. My arc is my main phone so I don't have the luxury of flashing ROMs and kernels all the time.
Do let me know if that's possible. If not, can you tell me how you guys do it?
My arc is running Stock ICS 4.0.4 with an unlocked bootloader.
I believe you got it all wrong.... you need to do a full wipe before installing a new ROM (to make sure it works properly and nothing is left from the old one).... not a kernel... You can flash kernels as often you want without any wipes. Just dont forget the WIFI-modules (only of needed by ther kernel).

Just think about it, it would be pointles to delete evrething and then restore it back..
P.S.: sh*t I pushed the wrong button and thanked you instead of quote....
yea..there is no point restoring the nand after flashing a kernel...full wipe and fresh installing rom is highly recommended..
Best way is to tryout a kernel..if everything is well and good then better stick to it.
afterall wat do u look in a kernel? OC,UV, good battery life and smooth UI..once you attain all these then stick to it..
btw i have tried many kernels this month without doing a full wipe..i never faced any problem as such..i just uninstall all OC, UV apps just to be safe
Thanks for the replies guys. And an extra thanks to Antochrist for his mistake. LOL!
Another reason for my question was because one of the kernel developers said to do a clean install.
Let's say I flash a kernel with additional wifi modules. Suppose I want to get back to stock kernel and its wifi modules, do I just flash the stock kernel or do I need to do anything extra to fix the wifi?

yea u just need to flash the stock kernel as wifi modules are included in the stock kernel itself

I think clean install only needed for new rom, not new kernel

Happy new years everyone!
I am pretty new to using custom ROMS and kernels and have made a standard noob mistake
which was forgetting to back up all the original software (ROM, kernel, etc). I realized this quite later
and though I have found the original ROM for my GT-P5110 I seem to have trouble finding the stock Kernel
(the one it had when it left the factory; 4.0.4) I did a search and have found my search-fu to be weak.
Can anyone help me find the stock rom for the GT-P5110 (Galaxy note 2 10.1)?
And one more thing, should I get the Galaxy S3 LTE vs. LG Optimus G vs.your opinion?
(I am in South Korea btw) Is Korean version is any different or any harder to root or to
flash a custom ROM, anyone have any experience?
Many thanks
But I did not get the Right Answer...

Thanks for the info that WIFI modules are included in the kernel and no extra additions need to be made.. I Don't know abt it ..
NOW assuming u now a lot abt Linux/Android could you please answer this for me..
- Does Restoring NANDROID
- Restore 'Stock Kernel' along with 'RIL file', RAMDISK - INIT### n stuff​
Which Hyperion users need to fiddle with..
But kernel and ram disk are stored in the boot partition so does NANDROID back that up too ?
and Can you help me with RIL file related info..
Thanks
NANDroid only backs up ROM. It doesn't back up kernel. Kernel is always flashed externally, it's the same with all Android devices.

Do I need to change kernel in order to flash the Hashcode's Jellybean?

Hi guys! Since I am a noob I haven't flashed a custom ROM before I wanna ask you do I need to change my kernel in order to put the amazing Hashcode's JB ROM. I already have a root privileges and TWRP installed. What are the steps then... There is hardly any info about the installation process in the ROM's topic. And how to install google apps - through the TWRP or? Thanks in advance. Waiting for your answers...
ROMS always have the kernel included. Everything is installed from recovery. Just wipe partitions, flash ROM, flash gapps, reboot.
Thanks man, I really appreciate. Will try!
What saved said....the kernel is included In all ROMS.
When life gives you tech....Make use of it.
