[Q] how easy is it to roll-back (un-root)? - Galaxy S II Q&A, Help & Troubleshooting

Hi all,
A quick question on how easy to roll back (un-root) and put back the stock ROM?
My current ROM is stock Telstra ROM. (just bought the phone today)
PDA: DVKF4
PHONE: DVKF2
CSC: TELKF3
Build Info : Jun 21
I know how to roll back a HTC Desire - by installing the RUU image from HTC or use the PB99IMG.zip install method to remove "root" and put back into std ROM.
I have yet to root my SGS2. Reason to un-root and go back to stock ROM is for warranty purposes. you never know what will happen (for example, my desire decides to dies on me yesterday, had to put back stock ROM to submit for warranty claim).
thank you in advance

Very easy basics are install stock rom removes root and use usb jig to clear custom rom counter .

if i do not install any custom rom, therefore, the usb jig is not required, right?

Nope. Jig is only required to clear the custom Rom counter, in case you have to claim warranty and return the phone to Samsung. And also to force the phone in Download mode, if something bad happens while flashing custom ROM etc.

hey cad,
Made any headway here?
I just bought an SGS2 from Telstra as well and I have a similar phone to yours.
PDA: DVKF4
PHONE: DVKF2
CSC: TELKF3
I too would like to retain the stock kernel, firmware and csc.
If we root with an insecure kernel, how do we go back to stock kernel if it's not downloadable?
Could we just flash another kernel if we are making a warranty claim and hope they don't check?
I assume CSC is where all the Telstra crap is stored and once we get ROOT, we should be able to back this up out of \system

Usual is flash a relevant stock rom or older stock rom and update via Kies.

Hi all I new to all this so could someone point me in the right direction...
1. I need a noob friendly guide to explain what rooting is.
2. How to root.
3 what is odin and all the tools required to root and flash custom firmware.
Video tutorials would be healpful. Im comming from a HTC HD2 but it feels like the explanations were easier to find.
Thanks in advance.

Root With Stock Bell Rom?

Now that the Bell Rom/Modem/Kernel are all available. I have a question that I have not seen answered, or at least not in a way that I understand.
With my old phone I used CyanogenMod for about 98% of the time a had my phone (1.5 years). I intend to use it again with the SGS2 but not till the it is a "Stable Mod" I don't like to use the "Experimental Mod" ones.
With that said, what I'm looking to do is have my phone with the same stock OS on the phone that is on it now, but With Root Access. So that I can install Apps that need Root and Delete the Bell installed apps (or even the some Samsung ones) that I don't want. Also I just want to get the ball rolling...
My question is, can this be done? Is this what the post from "Intratech" http://forum.xda-developers.com/showthread.php?t=1075278 is telling me how to do? With the option to install a third party ROM only "IF" I want to?
Or do I have to install a third party ROM after the phone is rooted because the Bell Stock one will not work.
Thanks,
P.S. I don't know if this matters but I do have a "Jig"
You can do it one of two ways. The easiest would be for you to flash a cf-root kernel which will install and after that you can just flash back the original bell kernel. You can also go the s2 root route by flashing an insecure kernel, running the s2 root app (might have to do it twice for it it work) and then flashing the stock kernel once again. Either way will leave you running stock with root access. The triangle will not appear if you are on the stock kernel. The jig comes in handy by resetting the flash counter.
Cf-root thread :http://forum.xda-developers.com/showthread.php?t=1103399
S2 Root thread: http://forum.xda-developers.com/showthread.php?t=1125414
Just tried http://forum.xda-developers.com/showthread.php?t=1075278 Guide on my (never rooted) SGS2 and didn't work...
The "Flashing Firmware with Odin" part of the instructions worked (i didn't see any thing changed on my phone, but all the checks and PASS and OK was there)
In the next part "Quick Root Guide" when I got to SuperOneClick part it just kept freezing on Part #6... I was using ver. 2.1.1 and then I tryed 2.1 then 1.95 and all did that same thing...
Looks like I'll have to try this Cf-root thing...
Well since Bell uses a KG2 kernel, just flash the CF Root JP_XSG_KG2 kernel from Chainfire's thread http://forum.xda-developers.com/showthread.php?t=1103399 and reflash the stock Bell Kernel. This is probably the closest way of staying to stock while still having root. Not sure if CWM will work, but I'm guessing you only want root with stock.
I'm not sure if Chainfire will release a CF root for the stock Bell kernel (probably will when he gets back from vacation) but if you're impatient and want to get rid of that bloatware, the JP_XSG_KG2 will give you root.
Hey any body here has the Bell Stock ROM
I need to reflash my bell Phone and I need the Bell Stock Rom again.
Thanx

[Q] Return-To-Stock Clarification

Hi guys,
Just to double check before I flash CF-Root, if I want to return to full stock including recovery, flashing a stock ROM without the PIT file will do so correct? I just want the option to return to a vanilla ROM and recovery if I choose.
I did search the forum, but it was all a bit vague.
Thanks!

Samsung has now put a counter on the phone which helps sales staff and engineers to find out if the phone has been rooted of flashed before.

Hi all - similar question as I want to (potentially) return my SGS2 to stock before I sell it. I have already rooted & flashed ROM so familiar with CWM / Odin / etc. but am unsure which firmware I should be using. Is there a difference for US / UK devices; how do I decide which one to download from Intratech's link ?
I have a USB jig so will reset the flash count afterward.
TIA

Any way of finding out by HW build / serial / etc. ? Phone was originally locked to T-Mobile but I SIM unlocked it.
I've seen on other threads that the Carphone Warehouse (CPW) firmware is unlocked so may be OK - any thoughts ?

Few Suggestions/Questions

Hello,
I've got S2 with Cognizant and Speedmod S2 Kernel. Everything works fine. I'll try to put it as "ordered" as possible.
Few doubts,
1) I'm a Rom Junkie(I came over from x10) and I don't have warranty, I see a lot of people got IMEI changed and even though they backed up "efs" partition, Nothing fixed (It's a hassle to take it to service center). Is there a proper way to safeguard "efs" partition (which contains IMEI) as per what i see on other thread.
2) I'm on a custom rom, How do I get back to official rom using KIES? Do I have to flash an official kernel or get back to official rom+kernel? How does this KIES thing work? I'm from India wondering if there is 2.3.5 update?
3) Why don't we have vodoo kernel just like GS-1? They were awesome.
4) if I flash the latest 2.3.5 will I loose the functionality to remove "yellow" triangle? Do I have to backup the bootloader or update the bootloader? Any clear info on this?
Thanks for all your help and responses, it would be appreciated.

hey buddy if you want to flash an official rom i would say do it through odin. go into the development forum original that is and find the stock rom thats in your region and follow the instructions through that thread.

My apologies buddy. If i knew the answers to your other two questions i would of answered in the order you wanted. apologies and i hope you get the info you want...
I dont have all the answers but ill tell you what i know
#1-Yes its a good idea to back-up your efs file.Not hard to do really.
The easiest ways would be:Full nandroid back-up,CWM(although conflicting reports of efs back-up in folders),copying efs folder to /data in phone and not internal-sd with root explorer(apparently internal sd looses permissions when copying).There is Hellcats KTool and apps like Nutrilaty also.Those to me being the easiest
#2-Kies needs to be installed to flash via odin as installing kies installs the drivers.Kies wont bring back a stock firmware,only Odin can do that and kies wont recognize your phone with a none official firmware.It can be used with an official firmware and a root kernel without problems though.If you have an official firmware in your phone and you plug it in to kies and there is a 2.3.5 update it will automatically advise you.
#3-that one i dont know.Sorry
#4-If you flash to 2.3.5 officialy or from another site you will be stuck with the yellow triangle as far as i am aware as it contains the new bootloader and can not be re-set with the jig.You can flash it here on XDA from this link
http://forum.xda-developers.com/showthread.php?t=1075278
which contains the old bootloader.Its 2.3.5 XXK13 and lets you re-set the counter and get rid of the triangle.

[Q] Updating firmware with CF-Root

Hi there,
Total noob here, so bear with me.
I recently bought a SGS2 and flashed it with CF-Root without any problem to KJ3.
Now, I saw there's this new KK2/5, with 2.3.6, and I was thinking about updating, if possible using CWM Manager. I guess I should follow the steps in the second part of this post.
Now my questions are:
1. Do I need to flash first the stock firmware? Or can I just directly flash the new CF-Root?
2. What does "factoryfs ("system") is mandatory part at the moment. " mean?
3. I noticed there is no stock KK5 in Intratech's thread so far (just a Frankenstein, still not completely sure what that means). Does that mean I cannot use KK5 CF-Root? Should I better go with KK2?
4. Can I flash directly CF-Root kernel and the rest of the stock firmware together? Or should I first flash the full stock FW and then flash CF-Root? Would I lose root and CMW then? That would mean I'd have to flash CF-Root via Odin, right?
5. Last stupid question. Where is the thanks button??
Thanks everyone.
1. You need stock firmware, CF-Root only gives kernel.
3. As previously answered, CF-Root goes side by side with stock ROM, if there's no stock ROM available for latest CF-Root, get a lower version.
4. You should flash first stock, then CF-Root. You will loose root & CWM.
5. The thanks button is just below this answer, near the Quote button.

I'd recommend you flash the stock firmware as there may be incompatibilities with the Kernel and existing PDA , MODEM and CSC. Plus no one just uses the newer kernel ppl flash / upgrade the entire firmware so that they can actually kernel is like the heart of the system responsible for power distribuation and stuff.

2. What does "factoryfs ("system") is mandatory part at the moment. " mean?

CWM is usually used to flash the kernel or zImage files. For flashing entire firmware via SD card i'd recommend Mobile Odin Pro by Chainfire which consumes the entire tar file and keeps root intact. This'll change your firmware and kernel while keeping you rooted just flash a CF-Root after that.

Frankenstein is just a combination of different Modem/CSC(Usually Multi) and PDA of the latest firmwares which is combined for the best performance is most importantly Non-Wipe ROM. Intra usually puts in a Multi-CSC for several region's use.

Thanks Az,
I can't see the Thanks button in any other thread. Do I have to write first before it becomes available?
So, if i need the stock kernel first, what are the instructions in the post I linked (CF-Root v5.0: Upgrading your firmware) for? Flashing full firmwares that already have CF-Root included? Wouldn't that be the same as if I got the other FW files (phone, CSC) from stock and added the CF-Root kernel (pda)?
Any idea about question #2?
Thanks again.
At first follow the instructions in this thread and flash kk2 or kk5 as you want the newest ;p : http://forum.xda-developers.com/showthread.php?t=1075278
Then when you flashed a full new firmware from that guide you can proceed to the instructions of CF-root with the matching kernel (kk2 or kk5 just the same version as you chosen in the previous step) from that topic to flash and gain root and CWM.
CF-root is only a kernel that is modified, so it is only a small part of a firmware but with nice extra features added.

Yeah it activates in the forum/thread you write in .....
yup stock kernels are signed by samsung and hence are requred for flasing over CF_Root kernels. as they remove the yellow triangle. factoryfs simply stands for factory file system it is recommended to include in case the newer firmware has a change in the file system / tables if you don't include it while flashing firmware using CWM you might end up bricking your phone. But the FW flashing process through CWM is pretty complicated and cumbersome i use odin as it is a simple job.
Thanks, everyone. Sorry for the crosspost, digi. When I saw your answer, I couldn't edit it for five minutes because I'm too new.
Anyway, I would try Mobile Odin Pro, but the country I'm in doesn't support paid apps, so it shows as incompatible with my device...
The only reason I'd wanted to use CMW was in order to avoid the flash counter (which is stupid because it is already on 2 or 3, I guess) and the yellow triangle removal process. So I guess it is not much of a problem.
Ok, so here's another question. What is this non-wipe stuff? It means I don't need to factory reset the phone after flashing?
Also, would you guys reccommend to use the Frankenstein FW with KK5 and the CF-Rooting to KK5? If these Frankenstein FW are created for better performance, the only difference is that they're not the stock configuration and won't allow me to update via Kies, but otherwise should give a better experience, right?
Sorry for being a scary cat, I just don't want to break my phone too quickly.

Most of the stock roms provided directly are wipe means they reset the system SD card when flashed. Intratech removes the script from the ROM specifically from the Frankenstein. About CF's Mobile Odin there are other ways to get it PM ChainFire himself for it and just give him a beer offline. Any flash of a different region via Odin will not allow you to update via KIES for that you need to flash the stock ROM of your specific region and then update it to the new ROM for your region it will as it is be provided by intratech in his thread eliminating the use of KIES entirely.
Nice, thanks. I've been reading on CF Mobile Odin, maybe I'll contact him and give it a try then.
So, any reason I should not flash the newest Frankestein FW and then root it with CF-Root?
Also, if CSC doesn't have anything to do with the supported languages, what does it do exactly? I read it is specific region settings, what if my carrier is not included? Would that be a problem? I live in China, using China Mobile.
Thanks, guys.

Sorry weekend pretty busy
Nope no reason why you should'nt ........ Frankenstein is pretty much stock only a bit tweaked .... personally i never flash CSC for my region ...... yea they are supposed to provide APN settings and all but for you guys there in china there have been certain issues .... i would recommend you flash the CSC after you flash the ROM your region's CSC would be available in the frankenstien section as well .... just ensure after flashing the ROM everything is in order.
Thanks digi. I almost forgot about this thread. I ended up flashing Frankenstein KK5 and then Siyah Kernel to give it a try. I didn't flash CSC, but I haven't had any problem. It seems APN settings are grabbed from the network or the SIM or something. I have no idea. What are the issues you referred to in China?
I am trying to find my way into a Chinese forum, but my limited Mandarin is making things difficult. After reading a lot, I arrived to the conclusion that most problems (battery, connectivity, gps lock...) are carrier/location related (I mean, if you flash correctly and everything seems to be running fine). So I thought I should try getting some local information. Hope I can achieve something, because I am getting really poor battery when wifi is on...
Is there any place where one can compare modem/kernel/rom/battery performance in relation to location/carrier. I think that would be sooo useful. Maybe I should give MIUI a try, since it is Chinese...

Unrooting help, a bit confused with all these different methods

Well I've googled quite a few key words to see if I could get the answers to my questions and I haven't found too much yet. I have a Bell Galaxy SII that's rooted 2.3.3 Android version. I ended up flashing my kernel long ago as well which gives me the yellow triangle now I don't care about that but i want to make my phone like it was when it came out of the box. I have the original firmware and kernel. What im confused about is there is Odin to flash this and that and then there's dumping the files on your phone and using Clockwordmod. what's the difference? which should I use and what do I flash first? the original Kernel then firmware? or other way around? or does it matter? youtube is nice and all but it shows customs unroots for branded S2's not mine which is Bell im having issues with my tethering disconnecting me from my computer so I think it's best if I revert back to factory since all I do is make phone calls and tether. Thanks guys

thanks, once I do that do I repeat the process in Odin to flash my original kernel as well ? and that should also remove my yellow triangle right?

No as you have just flashed an original kernel .
Reset custom rom counter with USB Jig .

the moment you flash a stock rom it will contain the stock kernel so you would lose root and all the custom stuff you had, basically what you have is an out of the box device

perfect thanks im just messing around right now with going back stock to see if that fixes my issue with getting Disconnected when I tether now I wrote all this info down so I can go back and forth over time and experiment with different roms
most of the custom roms do not support tether which sucks, but yeah its part of the fun to flash stuff over and over
agreed with above posters, flash it over and over again until you fully understand how the flashing really work
my sgs2 download counter has reach 16 because I was affraid to use cwm flash, so i went back and forth from original rom to custom rom
