Well yea, according to this thread i only need cf-root and then follow the procedure in post 2 for removing the yellow triangle. It's just that i've read a few step by step guides that tells me to use both CF-Root and SuperOneClick, but again they might have been outdated, or they didn't explicitly say CF-Root rather they said "One of Chainfire's insecured kernel" so i guess Chainfire's insecured kernels is different from these cf-root kernels...

Samfirmware just release DXKI2, Do you going to release CF-Root for it. Or recogment one to suit it.

rooting prob

i flashed the new ki4 package no problems. but when i try to flash the rooted kernel i keep getting fails and issues with odin {1.85} it just does not want to connect??

<ID:0/004> Added!!

<ID:0/004> Odin v.3 engine (ID:4)..

<ID:0/004> File analysis..

<ID:0/004> SetupConnection..

<ID:0/004> Can't open the serial(COM) port.

<OSM> All threads completed. (succeed 0 / failed 1)

Tried it with odia version as well and get same issue. every now and then my computer says device driver not installed. but i have updated with kies ect and even got drivers from here on xda to double check.

its annoying i really want a rooted device!

p.s. debugging is checked

Super Mega Noob time.

Literally just got my new phone. SGS2.

Its currently got the orange BVKG3 kernel on it. Firstly- Im guessing this is compatible with this guide (based off of the first post, seeing as it ends in KG3..) ?

I also can't see the CF-Root v4.1 actual file anywhere...only the Odin one is attached..?

EDIT- Ignore that... I only read the first post as I dont care about little triangles...

Finally, I am guessing before I start I will have to install Kies on my PC before doing anything else?

Sorry for the Newbie questions, rooting my Hero seemed far more straight forward...(from what I remember of it)

[Galaxy S II Original Android Development] MCOGW:
There's no problem with the kernel, you got a problem with the driver!

Check if any KIES-Process is running in the background, and if so: kill it before trying any ODIN-Flash.

If this doesn't help, try another USB-Port and/or reinstall SGS2 USB-Drivers...

One of these should solve your problem

---------- Post added at 12:23 AM ---------- Previous post was at 12:12 AM ----------

The kernel isn't bound to the CSC in any way! The CSC is absolutely non-essential if you're searching for the right version for rooting... same is for the Modem (Phone)- Part of of the firmware.

Just check if the the Kernel-Version matches your PDA-Version!

If you found the right one:

F-l-a-s-h IT :)

[Galaxy S II Original Android Development] kingkomarac:
Hi, I have new SGS2 and I just want to remove those useless stock applications like music hub, yahoo finance, game hub etc etc..... I found out that I need to root my device and than with some program delete it. But first I have to root my device, right?

Now if I do that do I loose my stock guarantee? And regarding that what I need to do to just root my device?

Are those the steps that I need to do :

Instructions - ODIN (long)

- Follow these instructions to the letter. Do not touch any buttons or checkboxes that are not listed below to touch!

- Unzip the attached CF-Root-xxx-vX.X.zip

- (USB) Disconnect your phone from your computer

- Start ODIN

- Click the PDA button, and select CF-Root-xxx-vX.X.tar

- Put your phone in download mode

- (USB) Connect the phone to your computer

- Make sure repartition is NOT checked

- Click the START button

- Wait for the phone to reboot

- Done (if it took you more than 30 seconds, you need practise!)

I'm sorry for beeing noobish, but I guess this forum is for those like me :)

I have flashed ideos huawei and clocked it to 729 MhZ so I know some stuff, but I don't want to mess up with my SGS2 :) So if anyone has some time to explain it to me or has skype or something I guess it doesn't take much time for this action. Thanx peops....

thanks everyone!
[Galaxy S II Original Android Development] timberwolf60:
you mean upgrade the kernel to 2.3.4? If for ROM on 2.3.4 which were European ROM, no Chinese and Thai languages. and DXKI2 was a ROM for South East Asia, it have all the main languages in the region including keyboard.

But fortunate, I used cf-root_KH3, it worked for me. wifitetheing was worked beautifully as well.

---------- Post added at 10:32 PM ---------- Previous post was at 10:20 PM ----------

Correct me if I am wrong. I used "csc select for S1 and S2", this ROM without XEU and XEN. It was a multi-CSC with the fellowing code: XSK, XEZ, XEO, XEH, XEE, VOM, VDH, TRG,TPH, TMS, TDC, SUN, SEB, PAN, ORS, ORG, ODK, NEE, EUR, DNF, CYO, COS and AUT.

I used XEE and it worked for me in Singapore.

Agree you. Because DXKI2 was 2.3.3 and I used cr_root kh3 which was 2.3.4. And Chainfire not going to do cf_root for DXKI2, So I am thinking to used insecure method fellow with SOC.

answer to my own post, i used cwm flash kernel and choose zImage(DXKI2), no more Triangle my kernels back to 2.6.35.7-I9199DXKI2-CL564948.

was my method correct?

---------- Post added at 08:18 PM ---------- Previous post was at 08:01 PM ----------

I was on DXKI2 and flashed to CF_root KH3. Then I used zImage which was extracted from DXKI2 by 7zip in PC. then I copied zImage into phone SD card. Used CWM from Twlauncher, choose flash Kernel. Reboot and it was working well. Then I used the same method flashed to ninphetamine-2.1.3+, tested worked as well.

[Galaxy S II Original Android Development] Nitrius:

Though another question, if you choose to update the busybox version, is it possible to remove it and go back to the one that came with CF-Root? Or do i have to restore a backup for that?

Edit2: And Superuser, according to the market there is a newer version out, is it safe to download that?
[Galaxy S II Original Android Development] stegmuellerm:
ok.

i have done now a flash back to kh3 and then again the intratech version

after that the rooting was working correct.

the solution with old_bootloader is definitly not running

Sorry if this is a noob question - flashed countless ROMs on my Desire, but new to the S2.

I'm used to ClockworkMod being installed by just being present as an update.zip on the root of the SDCard.

However, for CF-Root, I read:

"When going from CF-Root to another kernel, root will usually stay, while CWM will be lost (unless the other kernel also includes it), but there should not be issues. The CWM Manager app may remain, but probably won't do anything useful."

So does this rooting process bake CWM into the ROM?

If I then want to flash Villian ROM or similar (which has an included different kernel) then how do I do it, if it's baked into the OEM ROM by CF-Root?

Hi

thanks for your great work!

i want to root my KI3 2.3.5 and saw that you just uploaded an update to v4.2

it has "insecure" mode. what does that mean? is it more "secure" to flash the old version for KI3 2.4.5?
[Galaxy S II Original Android Development] Chainfire:
It means you always have root over "adb shell", without going through "su" or "rootsh" commands.

ok so I connected my jig (working!) to a normal usb cable, connected that jig+cable to the phone in download mode and flashed the cf-root kernel.

What is different to a usb cable with the resistor and a jig with the resistor and a usb cable connected to that jig? Did anyone ever successfully reset the counter with the new bootloader?
