[Q] do i need to flash an older rom before flashing to kitkat - Galaxy S II Q&A, Help & Troubleshooting

Hi, i'm new in these things so have a few questions.
Iwould like to flah thecyanogenmod but my galax 2s syas it is not a gt-I9100.
So i read some things about removing the assert line from a script and so on.
Do i need to flah an older rom before the cm11 nightly?
Do i need to flash the kernel first? or just use the latest cwm? (or rom manager/clockword?)
Can i reflash the S2 with an cyanogenmod kitkat version after i flashed it with an other kitkat rom for this device?
(still i did not succed to flash any rom to it)
thanks for any help !

First of all check if it g version or not.
To best of my understanding you can install it directly as far as you are rooted.
Sent from my GT-I9100 using xda premium

You don't need to flash an older version before KK. You just need KK compatible recovery. Or you can flash a KK compatible kernel, reboot to recovery and flash your KK rom.

---

Hello, thank you both for your replies.
Finally some clear answers
The model says GT-I9100 and not with g behind it, thanks.
I found some things about the status 7 error and about removing some line in a script in the zip.
So i will try the kitkat recovery (in my understanding this is also the kernel?) and then flash it with kitkat rom.
I would like to flash the one from cyangenmod, but doe it really mather which custom kitkat rom i take? At least they are all without the providers code like Vodafone or others?
Thanks again. I will update the thread if it succeeds or not.

Hi,
so i could not install the latest Recovery_CWM_6.0.4.7_I9100.zip as it gave an error E: signature verification failed.
then i tried recovery-clockwork-touch-5.8.1.5-galaxys2.zip and this works. But with this i can't install CM11. as i get the status 7 error.
So i will try some other versions kitkat compatible.
I also took a look at the kernels section but it is not clear wich one to use for CWM6 as i don't know what XXLSR or DDLS3 means, and which is correct for Netherlands.
Do you have any idea? (i am not allowed to post there yet)
Thanks for your help.

For choice of kernel -
1. Gustavo's - I don't remember the version. Check the op.
2. Dorimanx - you can try 10.43v100.
3. Apollo - 7.0b Cm
They will bring the KK compatible recovery you want on your phone. Then after rebooting to recovery you can flash any custom rom as they are not locked by any carriers.

If you are able to go back to download mode
1. Flash a stock rom via odin
2. Flash a custom kernel via Odin. You might find some in the link you put there or you can search for hirox kernel. Remember, you have to download Odin flash able kernel and follow the op.
3. Once you have custom kernel, reboot to recovery. Flash any of the kernels in clockworkmod mentioned in my previous post.
4. Reboot to recovery. Flash your rom.
If you are unable to go to download mode try all the methods mentioned in the below link to bring it back to normal. It will need patience and perseverance. http://forum.xda-developers.com/galaxy-s2/general/guide-t2345831

Thank you for your patience and your help Banjara.
This forum and it's people are 100 times better the on Gyanomed were totally no support is given...
I will try it and come back, at least the phone able to start in the download mode.

Probably the usb connector has some loose contacts as i can get no contact with pc.
I got this phone from my brother and he told me that it never worked, just loading the battery
So i tried an other cable from an cheap android pad, but also no luck
maybe tommorow, i have another cable from an android stick pc at my job, maybe it will work
else i have to open it to check the connector under a microscope and probably resolder(hotair) it with a lot of flux... what a pitty... :crying:
lucky i have some experience on it, i repaired a lot of qtek phone, some years ago, always that connector broken.
I'm originally an tv(crt,lcd,plasma) repair technician, but now on an other job

---

Pfew, i managed to rsolder the connector with help of the microscope on my job.
I could even connect to odin. so that's is good progression. i had a wrong kernel downloaded, so it failed.
now i have the correct one and will use Siyah-s2-v6.0b5.tar
But unfortunately the battery is really emptying quickly when it stays in the phone, i don't know why.
So i will have to charge it an then give it another try with this kernel.
The ROM should still be original as i did not flash it before, just the kernel.
The phone is now saying battery empty, can't download.
To be continued...

---

Jippieeee!
GREAT !!!!
It worked! flashed the kernel Siyah-s2-6.0b5 and it started ! :victory:
Now what is the best way to proceed, there are so many topics on this it is overwhelming.
Should i first flash a Kernel or first a rom?
Can i flash them right after each other? (kernel reboots) so ROM and directly Kernel in one go?
thanks for your help!

---

{SOLVED}
Ok this is solved, thank you guys and dolls !
i managed to flash the cwm 6++++ and then the OMNI kitkat (latest) and the gAPPs
and it is working ! i am verry happy ! :laugh::laugh::laugh::laugh::laugh:

---

:thumbup::beer::beer:

---

one more thing
i noticed there is also another kernel now in the phone.
How to get rid of the yellow exclamation mark?
i saw some footage on youtube how to do it with the correct kernel.
But can i also extract the kernel from the ROM.tar i used and flash it with Odin?
Or is there another way?
thanks for your help. ---> edit
ok found some here: http://forum.xda-developers.com/galaxy-s2/orig-development/30-10-2012-k-la-lp-t1103399
but is it also good enough to unroot your device or are some functionality's then lost when using OMNI- rom ?
Thanks for your help

---

there arent any funcions lost it just gives your phone informations so that it thinks its all fine and dont displays the yelow horror . Btw i used TWRP KK kernel on my gs2 and installed prerooted rom aosp neatrom 5.8 kk and dont have problems with triangle. Also neatrom 4.1.2 with extended battery life is there if you dont like kitkat =D

Thanks Radelos, then i will try to unroot it again. And that will be it then.
Now using the OmniKK nightly of 8th of june, it runs very smooth, no issues till now, all is working well. :good:

---

btw idk what is the exact rom your willing to use but for no triangle would also do an clean install of stock rom, then root with framroot that you can find here on site and then flash KK compatible recovery and ofc kk rom with it. Here is the rom i used, its prerooted and on first boot starts direct into recovery so its for lazy ppl =D factory format data/system then flash TWRP touch recovery and in cwm reboot recovery option. And then just flash rom
