And how is he going to manage that if he now has stock recovery??
If he has stock recovery he will need to flash the .tar version of Siyah via ODIN in download mode.

Actually, with 4.0.4, from stock recovery he could first flash the temp CWM recovery, and from there flash the zip of Siyah. That's what I did.

I wouldnt worry as this is 2 months old, and has been revived for some reason.
Anyway,he should have went back to GB and flashed siyah s2-v.2.6.14.tar if he didnt like ICS.

Yes, well that is different, your not actually flashing the kernel in stock recovery which was my actual point if you re-read.

I was just pointing out that there WAS a way to do it. Don't get so ruffled.
Edit: you may have misunderstood, and may not know this. From stock recovery you can flash the temporary CWM recovery .zip file, then from temp CWM recovery you can flash the .zip for Siyah or whatever other kernel. No Odin necessary.

Again, you're still not flashing the kernel via stock recovery, your doing it via cwm. The user who I initially replied to advised to simply download siyah onto sdcard then reboot into recovery and flash it which ISNT possible.
What you're advising is completely different and again, doesn't use stock recovery. Yes ODIN isnt used but that wasnt my point in first place, It was simply that you cant flash Siyah via stock recovery.

Actually, you said he HAD to use Odin. Which wasn't true.
But we're both nitpicking at this point. Let's just let this go, eh?

What is siyah anyway?

[Q]CwM Recovery Won't Stick!!

I am having an issue with flashing CWM via Odin and keeping it there. I flash CWM via ODIN, I've tried 3 diff versions of CWM , Red One, Voodoo (blue one) and the 3.0.0.8 via rom manager (orange one) each time i flash one, i can boot into after flashing it via ODIN, but when i reboot the phone. CWM is gone and its back to the factory samsung recover "for all devices" nonsense. I have been able to obtain root by flashing via the SU zip method and I have root, i just can't flash a rom b/c cwm wont stick....any ideas? search returns nothing!
Thats because you need a modified kernal for cwm to stick.
Here is the modified stock kernal for a froyo rom. put this in the pda function of odin.

you my friend have received a thanks, and are a great asset to these boards. It would have been easier for you to tell me to "research" but instead, you took the time to even give me a link.
+1 to you.
I appreciate the kind words sir, thanks!
even though i have flashed the kernel you have provided, my phone contiues to boot into stock recovery. (also thanks to providing the download link and thanks to person who asked question)

did you odin a cwm recovery after the modified stock kernal?
Make sure your battery is removed when entering download mode to flash cwm via odin.
Once it shows successful, remove the cable.
insert battery and immediately enter cwm using the 3 finger method.
Flash a custom stock kernel.
choose "reboot system now"
let the system boot up.
then boot back to cwm recovery and flash your rom of choice.

Install CWM without CF-root

Hi guys,
I have spent two nights reading many methods of rooting and flashing already, but I yet to come across a way to install CWM Recovery for my GT-I9100M without using a CF-root kernel.
The thing is, I want to keep the official 4.0.3 firmware I got from Kies.
I already figured out how to root without using a CF-root kernel. He does not have a CF kernel for my version anyways.
Back to my question. Is there a way?
I tried flashing the ZIP from ROM manager's website, but the recovery is only temporary. The next boot, it goes back to stock recovery.
In my Xperia X10, I could install CWM Recovery using a program after rooting. Not sure if I can do it for SG2.

You can flash kernels and you will not lose your official firmware.
All you would have to do is root your device and make a nandroid backup before you flash anything. Then you would have a copy of your firmware. Worst case, if you lose the backup, all you need to do is go to www.sammobile.com and download the firmware and flash through odin.

I see. Custom kernel is the only way to get recovery.
One other question though, is it okay to flash a ROM using a temporary CWM recovery (ie. recovery flashed indepedent of kernel)?

brick- can write a kernel, but not ROM

i tried going back to my original provider rom and got bricked.
i don't understand why ?
both are ICS ...
anyway i think i got now soft brick(?) i dont have access to CWM but i can go to DOWNLOAD MODE
and cant write to NAND .
i used odin to burn a kernel , but that is as far as it goes, i cant burn the ROM.
but vie odin i can write i think any kernel in PDA.
help me save my S2
If you can write kernel just flash Siyah and once done reboot into recovery and flash rom via zip file.
Simple.

thank you but how to get into CWM i know ...

there is progress!! :laugh:
i tried doing the same thing i already did, expecting the same result..
but somehow the phone manged going into "android system recovery (3e)"
it looks like CWM menu but i cant install any of the ROMs i have on SDcard or siyah kernels i have there to.
i can do cache and system wipe, but what good would that be for me ?
it doesn't have any access to backup or restore options.. so i cant restore the back up i have.

That's what I was tryin' to say, you gotta keep on flashing.
here, flash this rom (Code, CSC & Modem via Odin).

all i can flash is kernel
when i flash kernel all OK !
but when i tried what you said ODIN failed after attempting to write to "NAND"
I think you have a corrupted nand... first try to flash a good pit file (remember to tick re-partition), and start by flashing a stock rom to the handset, does that not help, then you have a hardware failure

[Q] Bricked phone help.

Hi,
I bricked my phone and I can only boot into download mode. I need a rom which I can flash using odin. Is there a way to use odin to install roms in zip format or do I need a rom in .tar or .md5? If so, could you give me a link for a rom in md5/tar format.?
Thanks

Thanks, but just to make sure I understand this right (I have the same problem) .. this will put the stock ROM on my phone, then I will have to root again, and then use CWM to put a custom ROM?
Is there a rooted ROM that can be flashed using Odin? I'm not too pick on JB or not, it will be replaced anyway.
Thanks again.

No need to flash stock rom.
Just flash Siyah kernel (.tar) via ODIN (This will give you custom recovery) then wipe data and flash custom rom of your choice. It will come pre-rooted and with its own custom kernel which you can then replace with Siyah again or other kernel of your choice.

when u have problem like this the best way is to flash a 'Stock ICS v4.0.3' firmware on ur phone using 'ODIN' to have a clean flash and booting of ur phone
then u can simply flash the tar version of 'Siyah kernel v4.1.5/5.0.1' again from 'Odin' in dwnld mode to automatically root ur phone and install latest CWM recovery, which can be used to install the custom rom of ur choice

He has no need to do that. As I said above all he have to do (If they want custom rom) is flash kernel like Siyah via download mode then flash custom rom in recovery. No need to flash stock unless thats the rom you want.

And that is exactly what has been advised. What's your point?
The user only has access to download mode so is assuming he has to use download to flash rom. It sounds like he isnt aware that he can easily restore his recovery via flashing a kernel. It also sounds like the user wants to use a custom rom otherwise he would already know that he can flash stock via download.
This is why its been advised to flash kernel via download instead of rom. That way once he has his recovery back he can simply reboot into cwm and carry on where/how he wishes like for example flashing his normal/preferred rom via zip like usual.
Read this thread again and see if he can actually perform a kernel flash just to get to cmw so he can go flash a stock rom.
Here's the answer: yes he could.
now...wouldn't it be better if he flashes a stock rom, take a long breath as he realizes he's not bricked (read the topic) and then flas a stock rom when he's sure about giving it another try?
read beyond the words kid, beyond the words
TheATHEiST said:
No.
He has no reason to flash a stock rom unless he specifically wants a stock rom. If he does then yes he can simply flash stock rom as normal but its my guess that he wants a custom rom since he was asking how he can flash a ZIP.
If that is the case then flashing a stock rom (.tar) would be a complete waste of time and it would be much quicker to simply flash kernel like Siyah and reboot into recovery and then even restore a backup if he has one or just flash a rom zip from card.
Oh and stop trying to sound patronizing, I'm 30 years old and no "kid".
@ OP
If you want a stock rom then read one of teh many topics we already have on stock roms/how to flash them.
If you want to use custom ones via cwm then simply flash Siyah kernal and then reboot into recovery and then do as your normally would.

[Q] S2 - Siyah-s2-v6.0b5 Complete write failed

I have used several custom roms, until recently when I had some issue with my phone overheating I decided to flash back stock rom. Now the heating issue has solved, but somehow I can't go back to root. At first whenever I used to root I used a CWM zip which I used to flash from stock recovery. Since now I'm comfortable with odin,I want to root via odin and still retain my stock ROM.
I odined stock rom on my phone so that means odin works fine, but when I flash Siyah kernel it says failed. What could be the problem?
