is it possible to root the SGSII without flashing the kernel?

Nope Sorry.

ok
then is it possible to unlock for free without root?
I just got a new SGSII and I don't want to have a big yellow exclamation mark my current one has

Then buy a £2 MicroUSB "jig" from eBay - that will clear it.

what do you mean "unlock without root?"
also there is a solution to exclamation mark if you flash custom kernels.

No you need root.
Flash CF root, then flash back your stock kernel, you will still have root but without the yellow warning triangle.

how to I backup my stock kernel?

No need to, just make a note of what kernel you're using, then download it from http://forum.xda-developers.com/showthread.php?t=1075278

1. It is not possible to root without flashing kernal
But you can update firmware to newest one via ODIN
2. You can unlock without rooting... Its called paying for the unlock code
Free is only through rooting
3. And why have you got another one if you already have a SGS2 ??????
Is that you are hooked on to rooting and bricking

ok so I flashed XKWDD_insecure through Odin
that went fine
but now when I'm trying to root with super 1 click it keeps locking up at step #5
anyone know what's going wrong?

Just flash CF-Root kernel and you're done.

If you gotten a new SGS2, should that not have come with the latest firmware version of that phone, in such a case, would rooting with CF-root not be better?

go to applications > settings > phone information
and note down the kernel version. (look at the KE, KF1/2/3 etc)
and compare that to the ones in that topic. Pick the one that is like it, or almost like it.

but since I've already changed the kernel thru odin wont that information already be skewed?

Well if you didn't note down your stock kernel and flashed a completely different one into it, then you have a problem. Im still very much new to android systems and XDA. (i registed today, but I lurked and read and researched for several days)
But, I think you can just grab one of the latest ones but I think some more experienced users here can give you a better answer on that matter.

heh I think I got it working
thanks for the help guys
I just downloaded the first file on the list
flashed it and it gave me superuser access
then I got Galaxy_S Unlock and it successfully unlocked my phone

Ok so i have taken a baring on how the Z1 acts and preforms on stock.

Now lets see what she does on custom.
"incoming detailed rants and rolls"

Ok rooted and debloated with kingroot.
Not to be confused with kingoroot.

Ok so I have been testing all day.. it's about 10%.. but still sucks.
Reading up on how to unlock the bootloader... nearly want to commit suicide due to the over complexity of it.

I don't understand what your problem is. You say you wanted to try custom roms. Then why do you have to deal with rooting and debloating. Just unlock bootloader and install a custom rom, which is pre-rooted. You can also install a custom stock based rom also pre-rooted. You don't need root to unlock bootloader...

I am not questioning why you wanted to try custom. My point was you didn't need to bother with rooting to go to custom. All you needed was to unlock bootloader (for which you need no root) and then install any pre-rooted custom rom...

Well it is a though situation with the Z1. I dont want to unlock the bootloader as it will remove the DRM keys and I cant make a backup of the DRM keys without being rooted. One solution could be going back to KK 4.4.4, root with available method then install bootloader and flash new rooted LP 5.1.1 ROM. But to much work setting everything up again so the Kingroot method is the most convenient then replacing with SuperSu. I guess though I am not convinced yet about Kingroot as I am skeptic about what info it sends to China, how it is used and what it installs in root aswell as if it injects any code to for say Google Play Services to gain control even if uninstalled.

Towelroot can you help.
It better then kingsroot because you can set up your own su manager (SuperSU or whatever)
I rooted my Z1 with LP with Towelroot version 1.0 when I have it correctly in my mine.

King root has some really nice features.. and a lot of really bad features.
Plus it feels very un trust worthy.
I want to unlock my bootloader but i'm on 5.1.1... so i need to downgrade first..
Rather just stick to stock at this point and pray kingroot is not evil.

But have you tried to replace it with SuperSu? I reckon there is a thread in this section with a former version of Kingroot and a script that uninstalls Kingroot and installs SuperSu as IIRC the later versions of Kingroot has "uninstall protection" in the way that it may remove the root altogether and/or prevent normal function of SuperSu.

[WARNING] IVY/IVY_DSDS POTENTIAL Encrypted Bootloader in OTA

OKay @MotexT have been looking at the ota package 32.1.A.1.185
I will be quoting heavily from hangout
MotexT
Wow, this is really strange. Looks like new algorithm for OTA
Click to expand...
Click to collapse
Hmm, clarify ?
MotexT
We all know how it works - we have updater-script which contain the algorithm of flashing files, right? Here, if I really got it, we don't have a classical scenario for that, which seems like new way to flash OTA updates

Yeah, i would reject this ota, but some people are stupid and will flash a can of yams if it's in a zip file
and that's not an exaggeration either
MotexT
All this file is almost about S1 boot security
Click to expand...
Click to collapse
someone actually tried to flash one of the defconfigs i zipped and attached to post
MotexT
Yeah, I remember ?
Click to expand...
Click to collapse
yeah there appears to be hashing functions in the kernel commandline as well
tell me this bootloader is encrypted?
MotexT
New one will be - there are certificates for all version and revisions, and looks like it encrypts the new bootloader after flashing
Checked out the files and yes - it will encrypt bootloader with SHA256 keys
Click to expand...
Click to collapse
Can you post that in a thread please?
MotexT
This file is for the first bootloader version
And it flashes some security into it
Click to expand...
Click to collapse
okay so does this really read as encrypted or signed?
This one is encrypted and checks if encryption was successful
It encrypts
Okay yeah let's upgrade that proposed thread to a warning.
i'm going to quote this hangout heavily so can you leave all those screens accessible?
MotexT
Yep, use them. Also highlight the lines where it's written, hope someone will do deeper research of all that stuff. Also I will add boot folder with all that files
Also it's strange at all - looks like this changes will be applied just after OTA - one guy has flashed new TFT an then he installed your kernel and my recovery and for him everything works well
Click to expand...
Click to collapse

So, I have uploaded the whole folder with this files to my Drive. For everyone who flashed the new version via Flashtool, don't flash any OTAs from Sony cause as @moonbutt74 have described in OP, there is some valuable changes. And yeah, they will still popping-up even if you have the newest version on board.

I don't quite understand what this means actually. I installed via flashtool, then kernel also via flashtool, then TWRP and everything seems fine so far. Anything I shouldn't or can't do now? And should others not update or what? What's going on?
Thanks for you work though!

In short, don't flash the ota. The ftf seems fine though with flashtool. and then if i have it right , only flash system .?
For anyone who is intersted in picking up development for this device I am attaching the kernel defconfig extracted from the kernel.elf/sin from the aforementioned firmware release. Linux/arm64 3.10.84

What exactly are the consequences when updating with ota?
What can't I do with an encrypted bootloader?

Hey! hahaha am sorry about flashing that zip file, no need to say that am a noob, I was thinking that defconfigs file was something like a configuration file for the kernel or somthing.... yeah I know... no need to say that I should not touch advanced tweaks but hey! at least my device is working ok! no bricks (luckily think so), no nuclear explosions they say... all good! thanks four your work again and for share your personal chats haha

Sorry I know that was a little harsh, but the joke was there, I had to go for it. Kudos on having a sense of humor! :good:
I've done some unbelievably stupid things myself! :silly:
The best one/ top of the list was that the first kernel build and resulting boot.img i ever managed to pack right went wrong when
i edited the updater script in the zip package to write to mmcblk0. Instant brick. xD

sorry noobish question, ive purchased my Xperia Z4 E6553 from second hand (used), and its already upgraded to MM fw.163, i did upgrade from flashtool to fw .185 and the chargind time its very slow,
how i can fix that ?
my bootloader says cant be unlocked cant change the kernel and install twrp

Perhaps you have Find My Xperia ON! You need to turn it off in order to unlock bootloader I had the same problem, give it a try after you disable it, restart the phone and the you go to service menu to see if it allow to unlock the bootloader.

I can't see a specific reply to this question by fayer3.
Can anyone spell out the consequences and rollback options for anyone flashing the OTA?
Is this likely to affect ALL future versions from Sony? In that case we should find ways to turn off OTA updates, to minimize the risk.

What?! No on flyme latest firmware. I HAVE DOWNLOADED the recovery it is ready but I don't now a way to check for 100% if it had worked so I don't want to flash it until there is a video or good custom rom. I don't have the cash to take a risk of brick in my phone

Most probably the reason for that is you can't downgrade, it seems your bootloader is newest and can't be downgraded back . This is most obvious thing

According to this Guide on this Forum "[Guide] How to downgrade from Android Oreo 8.0 to 7.0 (Non-rooted)" it shall work. I followed every step. Even if i try to flash the device, without making the mark at BL, it doesnt work. I always get fail, or i get stuck on Setup Connection.

So I root, flash custom rom, and then flash an older stockrom on? Will that be fine with the bootloader?
Where can i seek for help ?

Hm I don't know if u can downgrade your bootloader with TWRP ,it could be possible but can't tell for sure.
What I meant is you can use nougat only as custom rom.

Actually many apps are working just fine , thanks to magisk it can hide your root so u can use banking app,Pokemon go and many other as you have magisk .
As u seen it u can't go back via official way. Stay on latest stock without root ,no other way I'm afraid
Good luck
