Unrooting - Galaxy S II Q&A, Help & Troubleshooting

Hi,
If I follow this guide http://forum.xda-developers.com/showthread.php?t=1056334 and root my phone, is there any option to put back the stock kernel i had? because like CF says, this kernel have bugs, so maybe i'll want to put it back to stock.
Plus, what CF version should I install according to the following screen shot?

Yes, but the main idea is to put an official kernel and the latest is the best one (kf2). You keep your root access with a very stable kernel and if you combine with modem kf2, you will have a very good configuration.
Edit: I just looking your screen capture. You can flash again ke7 kernel once rooting process if finish. You will keep root access.

CF-Root-SGS2_XX_OXA_KF2-v4.0-CWM4.zip ?
Does it fit with my device? watch my original post edit

Why not using litening v1.5 ? You will have everything (latest modem, kernel) and a very good firmware with CMW 4.0 embedded.
Edit: http://forum.xda-developers.com/showthread.php?t=1095274

actually i just wanted a root, i dont want any other rom , i want minimal changes..

Ok, I misunderstood you, sorry.
You need an insecure kernel and not a chain fire kernel
Edit : http://forum.xda-developers.com/showthread.php?t=1101671
Edit2: flash an insecure ke7 one through Odin (quite same version of yours) and after reboot you need superoneclick Install on your pc. The main idea is to flash a custom kernel, do the root process and ref lash official kernel. This is the only solution.

And is this the proccess you suggested above?
Another question, will I be able to restore the device to a way which I can use my warranty if needed?
Thanks

If you have an official kernel installed, warranty should be preserved.
But odin flash counter can provide the information about this unofficial kernel flash you need to do in order to become root. To reset this counter, you need a small device called USB JIB available on ebay for 6 euros.
Thanks to this device, the yellow triangle will be removed (that warns you have an unofficial kernel) and the odin flash counter will be resetted.
So, this is why, installing custom firmware is not a big deal after that...

[Q] please,how to unroot my GT-p7510?

I know how to root my device by odin,first recovery-cwm_4.0.0.4-sam-tab-10.1.tar.md5,then Samsung_Galaxy_Tab_10.1_root.zip.
So,my question is how to unroot my p7510 so that it act as a new one?

Thank you for your advice.
in fact,i had read that aritcle carefully:
“UNROOTING & RESTORING STOCK RECOVERY
1. Using CWM Flash the stock rom for your device. This unroots your device and basically makes it like a brand new tablet.
2. Use Odin to flash the stock recovery from the filesfordummies.zip.
3. Done, your device is exactly how it was when you picked it up. ”

but i still don't know what CWM is,and is it just an app?
and in the step 2,i don't know where to get filesfordummies.zip.
I want to unroot my tab also. I followed the instroctions and I downloaded a stock rom from Samfirmware.com. How I can flash it with Clockworkmod?

Can someone help me? How can I flash the stock rom with CWM?
i used the instructions in the post that is referenced to unroot. then i had numerous force close. sammy phone support suggested factory reset. i did that and it took me back to out of the box. it then did the minor update to UEKG4, but it won't recognize the TW update. They are wanting me to send it in, but I know it is something with software and I should be able to fix it.
No signs of SU, can't figure out why it won't recognize TW update. Thinking about going back to CWM Recovery to see if there are some advanced options that could help.
Hey ANthesca, I'm having the same problem. It looks like the custom stock rom we went back to is the I/O version, and that version never got the touchwiz update. This is my guess as to why we can't update to touchwiz, I'm pulling my hair out trying to find the official USA Stock rom for my tablet

[Tutorial]root .62 with stock kernel (unlock bootloader requiered)

this is my first tutorial, hope it help
sorry for my english
some people going to say, "but, if you have unlocked bootloader, only have to flash a custom kernel with root", this method is for peoble that want to have their original firmwares .62 and stock kerner or in my case, people that can't flash custom kernel because of the problem of "1 bad blocks encountered" in the nand memory :'(
you need:
1) Unlock bootloader
2) a custom kernel with recovery (its not going to be flashed)
3) this file root.zip
4) flashtools
Intruccion:
1) save the root.zip to your sdcard
2) open flashtools
3) press the flash button (the one with the lightning)
4) Enter the option Fastboot mode
5) conect your phone in fastboot mode (phone off and press volumen + while connect the phone, the indicator led must turn blue)
6) press "Select Kernel to HotBoot" in the flashtools (in hootboot the kernel its no really flashed)
7) select the custom kernel with recovery
8) the phone restart, press continiously volume down to enter in recovery mode
9) in the recovery enter in install zip from sdcard
10) install root.zip
flashing this file with CWM the phone gain root access, i have only prove it with the mini, i don't know if it works for other models

Custom kernels already give root, after you have installed the kernel.

thanks for your answer
i know, but if you read the post, you see that some people CAN'T install custom kernels or some people prefer use stock kernel, this post its particulary for that cases
in my case, i unlock bootloader for flash custom kernel but i encountered the problem of "1 bad blocks encountered", a factory failure, so, i can't instal custom kernels, i find this solution for my particulary case and i want to share it, maybe someone have the same problem

[Q] I9100XWLS8 (4.1.2) - Spain (FOP) [23-01-12] factory reset considirations

Hi,
I'm considering to install this ROM and do a factory reset in order to clean all my carrier bloatware and customizations.
I'm wondering what should I expect to get in term of used memory and system storage after the factory reset?
I'm going to backup the following before the factory reset:
1. SD storage.
2. Possible phone based contacts.
3. My carrier APN
Anything else I should be backing up?
Thanks!

You could use Titanium Backup PRO to backup your user apps/appdata so that apps/app settings etc are restored.
No need to backup contacts as they're synced to google account and will restore when you re-enter account details.

That requires root access, which I have in my current rom, but also for the new rom.
Is there a tested rooting method for this rom?

Nice!
BTW, is that Siyah kernel based on the same original kernel build which comes with this rom (3.0.31-816988)?

No, that siyah kernel is not based on this Official JB4.1.2 kernel build but the earlier Leaked JB v4.1.2 for u

Couldn't this mixing of this official release and a kernel from the previous leaked build be the source for some unexplained bugs?
Besides that I've read the Siyah 6.0b4 release notes and I saw that they have some known issues (like startup scripts not running).
I'm hoping to get a more stable installation than my current rooted I9100XWLPT (4.0.4) (not sure which root I've used).
So I'm looking to do things more careful with this release, so I'll get a stable running phone
I imagine that Siyah will release a new build for the official release pretty soon.
I waited until now, so I think that I'll wait a little more.
Thanks for all the info and recommendations!

Rooting a S2 on 2.3.5 without wiping/losing data

Hey,
I'm looking for the best way to root my Samsung S2 phone without wiping it so that I can use TitaniumBackup and create backups of certain files/apps...etc
I've found the following thread: http://forum.xda-developers.com/showthread.php?t=1103399 but I can't work out if it's correct for me it does mention "K**"
My phone's "about" information is:
Android Version: 2.3.5
Kernel: 2.6.35.7-I9100XWKI8-CL616395
Build Number: Gingerbread.XWKI8
Baseband: I9100NEKI2

Hmm, I can't find any instructional thread for it, I did find the following file in the CF-Root post: CF-Root-SGS2_XW_NEE_KI8-v4.3-CWM4.zip which is XW_NEE_KI8: 2.3.5, CF-Root v4.3, SU 3.0.2, "insecure" it looks like it's for my ROM on my phone but not sure :S
Have you used odin before?
You just stick that file I said in PDA and hit start.

Best part of using Framaroot is that you dun even need a pc as its an apk. I also use TB to remove and freeze bloatwares, those that keeps running in the background, eating up ram, data and battery.
.......and the best part of using odin methods is that odin/phone are setup to bail you out if something goes wrong.
So just pick one and do it, and cydia impactor is a 4th way......lol

Two questions from a n00b

Hello!
I am going to root my honor 7, but i have some clarification questions first. Hopefully someone could kindly help me.
So, this is the procedure:
Unlock Bootloader
Flash TWRP Recovery
Install SuperSu from TWRP
My questions are:
1 - Is there a way to check if the bootloader is just unlocked on the H7? (I remember the "hidden menu" from Xperias)
2 - If i want to update to MM when it will be released, i need to unroot B170 (is it enough to select "Unroot" from SuperSU app?) and flash stock recovery. Is this enough?
3 - why should i need the stock boot.img? What is it exactly? Is it the bootloader? Flashing stock boot.img back does it mean that simply the bootloader will be locked again?
Thanks so much for the clarifications!

1 - I do not wish to check it now, but I remember if you reboot into bootloader there is a text indicating the status
2 - You need to have an unmodified system (and boot) for the OTA to work, so it could be safer to restore stock system.img and boot.img completely.
3 - I don't really know, hopefully somebody else will be able to answer. Last time I did an unroot+OTA upgrade, I did not have to restore stock boot.img.

the boot.img contains the kernel, and this is sometimes modief during a system update, and different version dont wpork on a certain firmware
for example, b140 and b170 use same kernel, as the on-or kernel by @sminki works (almost, but probably) fine, whoever, for what i know, it doesnt work on b121, because the kernel is different,
the latest full firmware is b121, so to downgrade or to unbrick, you need to install b121, so the boot.img also needs to be flashed, if you want it to boot
i hope that will explain it better
also to root, you can use the multitool by @inside!out, if you are not confident, or just too lazy:

amen brother :silly:
What about the bootloader? if i want to update via emui do i have to RE-lock it?
or maybe it will be re-locked automatically when reflashing stock boot.img?
last question, if i am rooted and unlocked, will i at least recieve the updates notification via emui?
thanks a lot. i am trying to study and get better "skilled" about android.
