Unable to install CyanogenMod 7 again!!! - Galaxy S II Q&A, Help & Troubleshooting

Hello guys,
I would have not made this post without a reason! I have searched the froum and used google for over 2 days but dont have a solution for my problem that's why i opened the thread!
My SGS2 was on CyanogenMod 7 and i decided to try the leaked version of 4.0.3 (I9100XXKP8 to be exact) so i preformed a full backup via recovery!
After this i flashed 4.0.3 using ODIN and used it did a root on it and istalled CM9. I did this just to see the real difference between the 2 firmwares. Everything worked great i had no problems at all.
After i was finished playing around with the firmwares i decided to restore my CM7 backup! I had no problems booting into recovery and the restore worked fine! no errors or anything. After i selected to reboot my device i got a Kernel Panic and couldn't do anything!
So i flashed KI3 stock from sammobile and rooted it via CF and then again i tried to install CM7 which goes fine through the install no errors! when i select to reboot the phone i have the ''Samsung galaxy s2 screen'' in a reboot loop! I reflashed the phone again with KI3 and tried again i followed the instruction step by step including wiping data/factory reset and wiping cache the same thinghappens. I tried to restore the CM7 back which i made, the restore process goes through but i get a kernel panic! So i reflashed KI3 again i thought it could have been the bootloader... i got the old boot loader and flashed it but i keep getting the boot loop! The strange thing is i can flash CM9 and it works but CM7 will not install on my phone at all! I have tried flashing it 10 times in the last 2 days.
Can anyone help me fix this and get back to CM7 because i dont know what to do anymore my flash count went from 5 to 39 in the last 2 days!
Note: i have tried using recovery and RomManager neither of them work! Also tried Stable CM 7.1.0 and nightly builds!

Hi,
i have tried this now and i am still getting a reboot loop! So it dose not work at all :[

I'v had the same problem. It was solved by flashing the .pit file for cm7 with odin.

---

That is very strange. I assume that you did a factory reset after that procedure?

Yes i reset everything there was i did this whole guide step by step about 20 times tried everything! i even had help from the guys working on CM9. They couldn't help and told me to open a thread here :[

Well, the pit file is probably the best bet then. Good luck when you get it.
By the way I meant a factory reset after the kernel clean and restore.
Kernel clean -> restore -> factory reset.

I have tried this still no luck :[ Also tried previous back ups but the are not working either. I also tried to flash Villian rom 3 now and the only thing that happens it stays on ''Samsung Galaxy s2'' screen no reboot or anything for bout 10 min. tried to go into recovery but it isn't working :[ back to flashing KI3 again!

Which kernel were you using when you originally made that cm7 backup? Was it the stock cm7 kernel or perhaps siyah's? The kernel panics are probably due to using a cm9 kernel(recovery 5.5...) to restore a cm7 backup and then using cf-roots ki3 kernel(recovery 4.2...)to restore a cm7 backup. I'd try flashing siyah's kernel(recovery 5.0...) through odin and then try to restore that backup.

Hv u try flash the cm7 twice in cwm before u reboot?

Good point, the first install is usually quick, the 2nd one takes much longer and does the whole shebang.

The forum won't let me post links. Just google search "Odin_+Pit_+_Flashguide_-_I9100.rar".

I was using the stock Kernel from CM7 to create the backup! The problem is i cant install a clean version of cm7 at all i end up in a boot loop! But if it try to install CM9 i have no problem? I will try to flash recovery 5.0 and try again :]

Re flashed 5.0.2.7 recovery and tried to do a restore. now the phone is stuck in a reboot loop again! So this dose not work either :[

---

Now i have also tried to do a fresh install of CM7 with the 5.0.2.7 recovery but it didn't work! I would be great full if anyone could help me!

Boot into recovery
wipe data/factory reset
goto mounts and storage > format system
install cm7 from sd card, then install it again right after
reboot
If this doesn't work throw the phone against the wall because this should work, unless flashing those bootloaders messed something up, or you flashed the wrong one.

---

as a last resort....
flash stock firmware.
flash cfroot kernel
try to flash cm again.
always works for me.
