If you want to Nandroid back to a JFD-based backup:
1.) Disable Voodoo
2.) Download and flash the Stock-Kernel-Vibrant.zip from the Frankin-Twiz thread
3.) Nandroid your backup

AFAIK Jac's kernel is still compatible with JFD. Making it compatible with JIx builds is something we owe to eugene373 in the first place as this used to be an issue.
I switched from rooted stock, to bionix w/stock kernel. Do I need to Odin back to stock or can I just nandroid?

Nandroid will get you back to stock but will not put you back to stock baseline JFD. Odin is the only way back to true stock.

Depends on which version of Bionix. Bionix 1.4 and below are based off JFD so you can Nandroid a stock backup safely. Otherwise you can flash the JFD kernel and Nandroid a stock backup, however this will not flash your baseband (modem.bin) back to JFD (but should still work I believe).
Thanks guys. I'm a linux user and don't want to deal with wine. So just wondering if I flash 1.4 or earlier then nandroid. Will that get me back to stock base band?

Just in case you haven't read this yet...
If you wind up using Odin - find a windows PC - don't take chances with Wine + Odin - Odin is bad enough as it is.
Also, make sure your phone isn't hardware locked if you haven't already. If it IS hardware locked and Odin fails, (as is very common), you'll brick your phone.
Yeah that is why I was trying to avoid using it. If I don't get an answer by morning, I will just try to flash down and report back here so hopefully people will have something to reference. I searched but couldn't find a definite answer.

I haven't tried it but flashing down should work.
Also if you are unable to get into recovery using the volume and power buttons you should return your phone for an exchange. This is consider a defect and you'll likely be unable to consistently get into download mode - not a good thing when experimentally flashing ROMS and kernels.

Why would you want to switch from Bionix?
Thread moved to Q&A.
Hi!
I'm a total noob. This is my first android phone. I've read everything about rooting, and I'd like to install a custom rom, but I'd like to save the stock rom/kernel first. I've found this topic: http://forum.xda-developers.com/showthread.php?t=1075278
I don't really know if these are what I need. Also, I have an xwkf3 device, but it's slightly branded for hungarian T-mobile (the browser has a different name and icon, and it also had every network setting by default).
So, basically I either need someone to tell me which one to download, or better yet, how to create a backup of the whole thing.
Yet again, I'm sorry for asking something probably really stupid. I've tried to google it many times, but I failed to find an answer. Thanks for everyone in advance.
Are you rooted already? If so just boot into ClockworkMod recovery (cwm) and then navigate to backup. (navigate using volume buttons and use home to select)

Here is the kernel rooting thread.
http://forum.xda-developers.com/showthread.php?t=1103399
Dial *#1234# into the phone dialer to find out what firmware you have installed.
Root using chainfires method and make a full backup via CWM.
Flash away. But make sure the Rom/firmware is for your device. Eg i9100 international.
Good luck.

I'm not rooted yet. If I understood everything correctly, the safe kernel is the same for branded/unbranded devices, and only the rom is different?
I'm currently downloading both secure and insecure kernels. After rooting, can I revert back to the secure one to install custom roms?
BTW, thank you for your quick answer

I'm not positive but I think if you are rooted and install a stock kernel (without root) you will lose root and won't be able to flash custom roms or make Backups. Its really easy to root, just find the appropriate insecure kernel, flash it with Odin, make backup, and then try new roms!

Don't flash back to stock kernel.
Use a jig if you want to get rid of the yellow triangle.
Edit: after flashing one of the cfroot kernels make sure you can get into CWM recovery mode. Vol up+power+home
If you can then you're ok to follow the instructions of the Rom you want to flash.

Thank you. One last question, if I may. Some of the roms I'd try use different kernels, then mine. If I install one of those, and want to revert the phone to factory rom, and kernel, should I root it again with an insecure kernel according to the rom, or one according to my device's current, factory rom?
You will probably find that the Rom kernel will be rooted and have CWM. Just check in the 1st post or 2 of the roms thread.
If you use CWM and make a backup of your stock Rom, after you root now but before you flash any other Rom, you can restore with CWM to get back to stock firmware.

To fully return to stock you have to flash a stock rom and stock kernel from Odin. The rom that you want to back up will be a stock rom but it will be rooted because of the rooted kernel. So yea, flashing stock firmware and kernel is the only way to get back to fully stock.

But if I restore my backup rom, and flash it with an original kernel, it would be unrooted, and basically the phoen would be just as it is right now. Is that right?

Hi everybody,
I'm new at this forum and in the Android world and I have a few questions about the install process of the ICS CM9 on Galaxy tab 10.1 GT-P7500 3G.
1. If I want to backup my current ROM, do I have to be rooted to use ROM Manager to backup the ROM? And do I have to be rooted to restore that backup?
2. Can I UNROOT my device later? (The device belongs to my father's work and I don't want to take any chances with the warranty things.)
3. How to install the ICS CM9? I think I have all the files I need to so, I hust need the guide.
Thx for your help!! I really hope that I will get this thing going already!
Yes, you need to be rooted in order to install cwm through recovery and then make a backup (although you don't need rom manager. In order to flash ics you have to install pershoot's recovery with odin). You can unroot later, but you have to remove the recovery as well if you want your device to be covered by warranty for sure. So flash with odin a stock rom and you're ok BUT you may loose the data.
Listen, ics installation is tested and almost fool-proof. But bear in mind that a lot of things can/may go wrong and then you'll find yourself in a mess. Since that tablet doesn't belong to you, you should better leave it be, unless of course you have your father's consent and you have explained him all the risks involved.
It wouldn't be nice to find his tab messed up!

Try to Google it. It may come up. You can backup your device through cwm but I would also find the stock firmware if you are going to want it in the future.

OP... Why are you so hung up on ROM Manager???
Just root using the Odin method mentioned, once you've rooted and have CWM installed just do all of your backing up, restoring and flashing through it. ROM Manager is nice and all but it has its own set of issues and all. Read and learn about what you are about to do... You'll be surprised how easy it is and you'll run into alot less problems.
Please put the ROM Manager down and step away.

Are there any custom roms which are better than the latest stock rom for the galaxy s2? I'm new to all this so this could be a stupid question.
I want to root my phone and maybe flash it with a custom rom. I have never upgraded the stock firmware on my phone because I did not want to lose the data in my apps and now I want to upgrade the phone and keep everything so I'm going to root the phone and use titanium back up. My android version is still 2.3.3.
Why do people flash an insecure kernal? (except for the reason of rooting the phone using odin)

Better or not is subjective. The only way for you to find out is to try it out yourself. Someone else's opinion of better probably won't match up with your opinion or mine.
However, most custom ROMs will require you to do a full wipe of your phone, which means you won't be able to fully preserve your data... so you'll have do stick with your plan of root first, and use TB to save your app data. You can then restore your app data after you install whatever ROM you want.
Insecure kernels are used to root, there's really no other reason for them to be flashed.
If you want to invest time in your phone and tweak it to the maximum, a custom rom / kernel is recommended. They often contain extended settings which can improve comfort and performance of your phone, but they also require some technical knowledge and carefulness.
If you are just happy with your stock roms functionality, there is no need to change.

I don't mind investing time, I want to tweak it to the maximum and be able to do anything I want. I was planning to just root it using super one click, backup my app data using titanium back up and then upgrade the stock firmware and then root it again so I can restore the app data again. As I am new to do this, I'm doing proper research so I don't do anything wrong. I might also flash a CM Rom to my phone if I understand how to. I don't understand the insecure kernel and how it is different from the stock kernel.
Where did you learn to do all of this?

Here's a guide to rooting Gingerbread:

Don't use Super One Click or anything, use a CF-Root kernel. When you flash the compatible kernel you'll be rooted and have installed also ClockworkMod Recovery which will allow you to install custom ROM's.

I just did this yesterday.
First root gingerbread.
Do a full nandroid backup.
Backup efs and apn using the guides on this forum.
Backup SMS using SMS backup.
Sync contacts to google or export to sd card as vcard.
Backup apps and data using titanium backup.
Copy all data off the phone onto your computer just in case.
Perform a factory reset.
download latest firmware from sammobile.com and flash onto phone.
Root using cf-root and use import or sync to retrieve contacts, SMS backup to restore SMS, and titanium backup to restore apps and their data.
At this point you should have a working phone with only call logs lost.
First couple of charges after a flash the battery will drain quickly but will settle down after that.
You just want to have rooted stock? You'll need to upgrade to ICS first before flashing a custom kernel.
What you could do, is upgrade to stock ICS through KIES flash a CF-Root then proceed from there.

If you are still on 2.3.3, I would recommend you to root it with zergrush method because it doesn't increase the binary counter.
Go to this link to download InitialCFRootFlasher.zip (from Chainfire), and then download CF-Root kernel of your firmware. Follow the instruction carefully and you S2 will get root with 0 binary count. This wouldn't work if you have updated your firmware to 2.3.6 above.
There are rooted stock ICS firmware which can be flash directly using CWM Recovery, so there's no need to use kies at all.
I would recommend Rootbox. There are two, one in jelly bean, and one in ics. Either one is really good.

I went through your thread but CF hasn't made an insecure kernel for KH2. A few users had the same problem and used KH3 as stated by CF but some ended up running into difficult problems and some had no problem. Should I use KH3 to root or should I use another method. I only want to root gingerbread so I can back up app data. I might then factory reset and update the stock rom or flash CM10.
okay so I read through some of the threads and I still don't know how to fix my issue. I rooted my phone using Odin v 1.85 and used siyah 3.4.2. I did it successfully and everything was good. I then gave the phone to my cousin and he said he performed a factory reset to get rid of everything on the phone ( contacts ,etc). Now when I turn on the phone it shows the samsung galaxy display with the triangle and then the screen goes black and just blinks. It still goes back into download mode I just dont know what to do to fix the problem. I know I'm a noob but please HELP!!!
Development section. You'll find the stickies that show how to flash stock packages with Odin. Go back to stock to fix your issue. You should then be able to load a new kernel and flash a custom rom.
Oh, and never let that cousin touch the phone again.

You will need to root first. If you did not flash the stock plus root package already, flash that, and then install a custom kernel which has ClockworkMod Recovery. Then you can flash any firmware.

Flash a kernel with ClockworkMod Recovery, then boot into recovery and flash the firmware. Mobile Odin can't handle the CWM flashable zip format.
There is a Siyah kernel for gingerbread that would give you CWM so you could then flash a custom rom. It would be in the development section. Just make sure you grab the version for gingerbread and not ics

I assume you mean nandroid backup from ClockworkMod Recovery? No. It's mainly a space issue, where you want to store them, because they take up quite a bit of space, especially if you have several.
