Hi, I am new to Android, , just got my GT10.1 3G [EUR] last week. I am thinking of flashing my tab with the oc kernel from
droidbasement.com/db-blog
So i am just wondering, where can I find a copy of the stock kernel, just in case something goes wrong. I tried searching in the forum but couldn't find it.
My current kernel:
2.6.36.3 [email protected] #1.
Or maybe the kernel comes with the stock kernel?... I'm not sure
Also, is it ok to flash to the Overcome 10.1 Series v1.2.3 rom but use the oc kernel?
Thanks in advance
HI there...what you need to do is do a nandroid backup of your stock rom thru CWM before you flash the new kernel..then if you decide to go back to the stock kernel, via cwm go to restore, advance restore and then choose restore boot...this will get back your stock kernel.
Thanks alot for the info... also is it save to use the
Overcome 10.1 Series v1.2.3 rom
but use another kernel?
You should check out the particular thread..iinm there are a few ppl who reported that there were some problems when using overcome with Pershoot...well you can try and if you face any problems,at least now you know how to revert back....don't forget the "thanks" button...good luck!
I can't seem to find the "thank" button on the lower right corner... weird
maybe its due to my low amount of post??
I'm kind of opening this thread again. I have tried to search for this.
I wonder what is the easiest way to get hold of the stock kernel if I forgot to make a nandroid backup?
Now I have lost 3g cous I flashed the wrong kernel.
I run on ICS italian rom.

Is there any place to download the stock kernel for the GT Wifi? Or is there a way to back up the current kernel? I looked around and couldn't find anything about this. Reason I ask is because i want to install pershoot's O/C kernel but I want to have a backup of the stock kernel incase I need to revert to stock. In case it helps, I have the KG6 version.
Thanks

If you're running stock kernel now, you can make a nandroid backup in cmw, then go ahead and flash Pershoots kernel. Then if you wanna go back to stock kernel you can go into cmw/backup and restore/advanced restore, choose the backup that you made and then just restore boot and you'll be back on stock kernel.
thanks. I didn't realize that nandroid also backs up the kernel. I thought I read somwhere that it didn't. Gonna go flash now! Thanks!h
hi!
I plan to root my SGS2 phone (using odin to put a CF-Kernel on it) and then I plan to install e.g. CM7...
But I want to backup as much as possible in advance to be able to return to stock as close as possible. because of this I want to backup my very on ROM (which is at the moment samsung 2.3.4 stock with TouchWiz), so that I don't have to download a stock-ROM or something like that...
1.) Is it possible to backup my current ROM (e.g. via CWM) so that I can return to this when I find out that I don't like CM7 for example? so that I won't need to download a separate stock-rom to get to my current stock-rom, because I backed my current ROM up myself?
2.) if this is possible, can I then use KIES again after I recovered my own current stock-rom after I decided to not use cm7 anymore and I want to eturn to my own stock-backup (that I backed up in advance - if it was possible (see previous question)) to then use KIES to update e.g. to icq cream sandwich when it's released next year on the "nomal" KIES-way...?
3.) according to that I have this post, where I ask, if it's possible to backup my stock-kernel before replacing it with CF-Kernel... I'd appreciate help there, too, very much!
thank you very much!!
Read what is your current rom at about section and take notes about rom and kernel.
Then go to Intratech's thread, find your firmware and original kernel,
Download and keep in a safe place.
Use Odin to flash back to stock wit the firmware you downloaded.
Cheers.

However its untested by me how you put it back.
Also look at Post 9 from oinylicious in this Thread, you can use Zergrush only for temp root instead of Doomlords Tool where you get permanent root.
This works for the whole Phone, not just the Kernel
I did exactly what your planning.
I had a stock phone and firmware.
Used cfroot kernel to root.
Did a nandroid backup or CWM backup.
Did a titanium backup of apps.
Flashed CM7 nightly Rom.
All was good but wanted to go back.
Did a CWM restore.
Was back on stock all good as before.
Did the same with miui.
Actually I can go back and forth as I have CWM backups of each type.
Hope this helps.

thank you! yes, this is what I inteded to to. when this really works, it's great.
sorry for the noob question but "nandroid backup or CWM" is already included in the CF-Kernel, am I right?
the resulting question would be if it's possible to backup the original kernel... before I flash the CF-Kernel... I asked it here...

If its the CWM and ROOT Kernel yes .

No but you should find matching kernel in stock roms thread .

hi gänsebraten, thank you very much for your hint. I read your linked post now. it looks very promising. and is exacly what i mentioned. but...
although, if it's still not shure if it is possible to restore the backed up files via your method... it's like playing with fire... I'm referring to your post...
did anyone tryed this way to backup and restore KERNEL and ROM and can confirm it works? I'd appreciate it very much
So i rooted by flashing, via odin, CF-Root-SGS2_XW_XEF_KJ2-v5.0-CWM5 over the stock 2.3.6 rom from kies update. I then flashed cm7.1 stable successfully after a nandroid backup of the original rom.
Now question is, if i perform a cwm backup, do i get back to stock rom, with my apps intact?
Another question about kernel: My kernel version doesnt have I9100XXXX in it, how do i pick a kernel version if i wana change/update my kernel with cf-root?
Thanks for the answers .
just restore from nandroid backup and everything will be as it was when you did backup
restore backup or reflash it
Thanks for the answers, any thoughts on the second question?

what kernel have you got? what kernel you want to have?
I managed to flash siyah kernel successfully with no crashes and what not. but one problem persists: when i start the phone everything is ok, but after i lock then unlock, display quality drops and everything becomes grainy, poorly drawn and somewhat pixelated. Anybody has an idea about that?
Should i just flash another kernel all together? what do you recommend with cm 7.1? I read somewhere about the stock cm7.1 kernel, where could i get that?
Seriously sorry for so much questions, but i think you can see how the issue is bugging me. Big Thank you for answers..
Hey Guys
I rooted my phone yesterday finally
I however wanna install a new rom/custom kernel on it. However reading the reviews of roms, they have some bugs that i wudnt want..
After quite a bit of research, i found the speedmod k3-25..
Now my basic goal is to have a better performance and better battery life...and i have heard the speedmod does exactly that.
Now my questions are:
1. Is there any better kernel or a stable rom (by stable i mean no bugs in common usage) that enhances performance better than the speed mod?
2. I can directly flash the speedmod kernel after booting on CWM and choosing the speedmod zip, right? And it can be done on stock firmware and kernel with stock rom?
3. I will make a nandroid backup of my phone.. In case something goes wrong or i am not satisfied with the kernel, can the nandroid back up revert my phone to the previous state as it was with all apps and data intact? or should i use titanium backup..but in case the phone doesnt start, titanium backup will b useless.. :|
4. Lastly, will i need to a factory reset/wipe before i install speedmod or just need to flash it directly
Please answer the quesions
thanks

hi guys,
i have a samsung galaxy s2 (GT-i9100 - NFC), which i got from orange end of 2011. I the in jan 2012 got help from this forum to root my phone and change the rom from the original to:-
Rom & Build No: VillianROM 3.0
And' ver: 2.3.5
Baseband: i9100XXki1
Kernel: 2.6.35.11-ninphetamine-2.0.5+ninpo @ titan #20
Although the phone works okay, i'm beginning to notice a lot of slowdowns and regular reboots, so i want to go back to whatever latest google android OS the S2 can handle (rooted). I've forgotten what to do and would be most grateful if someone could please help me with the following:-
1. Whats the best software/method to backup everything?
2. What is the latest rom (original, but should not have a provider's bloatware) i can use on the S2?
3. Once backed up, how do i change from VillianRom to the latest/best OS currently available?
4. How can i root the original rom?
Thanks once again

For official stock rom, check
www.sammobile.com
And search latest stock rom for your region.
If you like custom rom, then there are so many roms on xda. I like omega and alliance roms. Choice varies from person to person

1. Depends. You can do a backup in CWM to image your device or you can use Titanium Backup Pro to just backup your apps/appdata and restore to new rom.
2. http://www.sammobile.com/firmware/ < Check your device/model here.
3. Well just so you're clear, There is no "best" its subjective. Also "latest" depends on what type of rom you want to flash like Sammy/AOSP/AOKP/CM/MIUI etc. To flash latest samsung do it via ODIN, to flash any other do it via CWM. All info you need is already on forum.
4. By flashing custom kernel via ODIN.
All your questions have already been answered countless times.
Thanks very much guys. I simply want a fast lean rom as some seem to be slow running.
Doesn't get better than this.
sendign the phone for warranty?
you will need to flash back the original rom and unroot your phone.
if they found your phone is rooted the warranty void, experience it before so be aware of this.
Let me thank you guys for advicing me. I am most grateful. I read your posts a bit late and in the meantime, I think i have bricked my phone as i've flashed Samsung's original FW (I9100PBVLP8_I9100PORALP8_ORA) from sammobile.com. I used Odin v3 and successfully flashed the phone, but it's simply stuck on the boot logo. I have even done the following:-
I've managed to wipe the cache partition, but the recovery menu has No advanced options. It says:-
ANDROID SYSTEM RECOVERY <3a>
reboot system now
apply update from ext' storage
wipe data/factory reset
wipe cache partition
apply update from cache
test redband fota[FS]
But i still cannot get it to boot. I have also tried to use an old nandroid.md5 backup i made, but odin reports the file as invalid.
I'm desperate guys, please could someone help me.
Download Mode and re flash.
Are you sure you are flashing the right ROM right? Check under the battery to see the Device Model.
If it's i9100, then make sure you are downloading a i9100 ROM.
Thanks very much for your advice gastonw - i have managed to fix the problem now by going into system recovery and doing a factory reset, so thank you.
Although everything seems to be working fine, i would have preferred a more newer 4.2 jelly bean rather than 4.0.3. Oh well beggars can't be choosers and all that, lol! I guess i'll have to re-root it again.
gastonw mate ur a star! I've installed the latest JB rom u posted earlier and i'm very happy with it.
Now before i damage it beyond repair, how do i root it safely?

Hi You could try this method http://forum.xda-developers.com/showthread.php?t=1501719 its quite safe so ether should work or wont, if don't no harm done as it doesn't need a insecure kernel.
I'm quite new myself @ this so plz use caution when trying it out.
Peace

Good to know man, enjoy it
About root, I've seen a couple of methods laying around the threads, I'm sure they're safe.
I still think that ExynosAbuse app is the fastest way to Root now (one-click).
Here's a vid. I never tried it tho.
Thanks very much for the links AnubuRe and Gastonw.
Gastonw mate, i have been playing with the rom you posted a link to. Don't get me wrong, it's great and very fast, but the downside is that it doesn't have a huge number of options to tweak etc. Now someone mentioned a rom called Neatrom, but i'm wondering what you can recommend? I don't want a bloated rom...i want a fast rom, but with some options to allow me more greater control over the phone.
Also, i know this is a bit off-topic, but can you recommend me a widget app, where i can quickly dial phone numbers i.e. by touching a person's photo?
