Weird superuser - Galaxy S II Q&A, Help & Troubleshooting

Hello,
I have an sgs 2 and the jack broke, so i want to give it back to repair. The phone had CM7 flashed, so i flashed stock branded firmware. The only thing that makes me uneasy is that the superuser app is still there, and the root is alright. How should i remove it ?

There are different ways for unrooting.
Depends on the way you rooted.
One easy way IMO is to wipe data / do a factory reset, then re-flash the whole stock ROM with Odin to your phone.
Good luck !
P.S.: Hope that you have reset the flash counter. Maybe this will be checked.

So i downloaded the check root app, cuz i just went back to stock rom, so after what you said i should already be without root. I checked if i am rooted and i am not. But still there is a superuser app in the drawer. How should i unistall this app ? or is it in the stock rom also ?

[Q] A new SGS2 user wanting to use a custom ROM

So hi all, I got my SGS2 about 2 weeks ago and so far am really liking it. I, however, am intrigued about the features that a custom ROM could provide.
Currently I'm looking at Cognition S2. I've read the installation instructions and browsed around the forums reading about this stuff. There are, however, a couple of questions that have risen.
1) Do I need to root my phone before being able to flash Cognition S2? If so, is the best way to do this by getting CF-Root?
2) If I flash said ROM, will I lose all applications and data? If so, is there a way to back them up first? I've read about people recommending Titanium Backup, but even that requires the phone to be rooted so this seems like an egg and a chicken -type of thing to me.
3) If I flash a custom ROM, is there a way to reset the phone back to it's "original" state so that, in case it dies during the warranty, Samsung won't just tell me to get lost because I've flashed it myself?
Basically I'd like to flash, but not if I jeopardize such an expensive toy.

1. Yes.
2. Yes but once you have root, install Titanium, do a back up and then flash Cognition rom.
3. Yes provided you find the correct version of your carrier's software. But beware : if you don't read carefully and screw your phone up with a bad flash, you might not be able to do it yourself.
Read more and then follow instructions exactly.

Yes, your phone must be rooted before flashing (most ROMs). Simply flash CF-Root kernel via ODIN and you are done. Really easy.

Most likely all your apps and settings would remain, BUT. I would highly recommend to boot into CWM recovery (you'll get it by flashing CF-Root kernel), do full wipe and only then flash new ROM.
To backup your apps use AppAdmin/AntTek app Admin/Titanium Backup or some similar app. Titanium Backup has an option to backup app settings/data. Personaly i would NOT use it, but that's another story.

1. Flash CF-Root kernel.
2. Backup your apps/contacts/text messages and so on.
3. Boot into CWM recovery and backup your current ROM.
4. Wipe.
5. Flash new ROM

And yes and no. you can restore phone firmware (if you made a backup on step3), you can flash back stock kernel, but SGS2 have two(?) hidden counters that shows how many times you have flashed custom kernels. If counter shows something else then 0 - your warranty is lost. At least it should be like that but friend of mine got repaired his SGS2 with no problems while his counter was showing "3". Perhaps it depends on person who work at repair center.

[Q]Possible to go back to stock and unroot?

I have just moved from my old GS1 to the GS2 and I am super impressed with the speed of this phone. I am however tempted to put cyanogen on this phone however as its still fairly new so want to keep my warranty until I know if there are any issues with this phone.
If I root my phone and perform a NAndriod backup, is it possible for me to go back to stock with no signs of the custom flash? I know its a n00b question, its just that I have never tried this before...

Yes you can!!
You will need
1) An USB jig
2) Knowledge about rooting/installing cwm
3) Balls to flash like a maniac (No, im kiddin')
After rooting with insecure kernel+superoneclick tool method, or simply flashing cf-root kernel, install codeworkx kernel.
http://forum.xda-developers.com/showthread.php?t=1118693
Now install your CM7 rom.
To go back, restore your nandroid backup (of your original stock ROM) or flash any official ROM from this thread.
http://forum.xda-developers.com/showthread.php?t=1075278
Use usb jig (buy from ebay or few XDA members actually sell it!) to reset your binary count so that Samsung won't know you have flashed unofficial roms and kernels on your phone. If you are still worried, first use Superoneclick tool to Unroot your phone, then use jig to reset the counter.

Can ClockWorkMod be uninstalled?

I'm looking for a solution for rooting my GT-S5830L in another thread. But while I'm waiting on that, maybe someone could confirm this for me.
I've read that ClockWorkMod can be uninstalled, at least in Froyo, by doing the following:
Deleting: /system/bin/hijack and /system/bin/logwrapper
Then renaming: /system/bin/logwrapper.bin to /system/bin/logwrapper (<- No . at the end)
I've read that in several places, but haven't confirmed that it also applies to Gingerbread. I have 2.3.4.
Thanks folks.
http://forum.xda-developers.com/showthread.php?t=1437426
Well mine is S5830LUBKP7 GB 2.3.4.. and I've already lined up a procedure to flash a ROM of that I got from sammobile with Odin if needs be.
Are you suggesting that ClockWorkMod can't in fact be completely uninstalled without flashing a stock build?
must reflash with Odin
Sent from my GT-S5830 using XDA
2nd opinion suggesting just deleting and renaming files doesn't do the job. Hummm...
Any more votes?
there's a flashable stock recovery floating around somewhere in the forum, use the search, might work alright. Other than that, Odin.
It seems you're probably worried about warranty. If you ever need warranty for some reason reflash the stock rom from Odin and that's it, gone CWM, gone root, gone any reason to own an open source OS smartphone.
Otherwise, it's really not recomended to be flashing custom or stock modified roms without having the option to backup and restore your phone's system, which in my opinion is the most important asset of CWM.
Don't worry, you can always go back to stock with Odin. But once you root and start flashing, you WON'T GO BACK; there's really no other way to go beyond the factory issued limitations of the ACE.
try Odin

I did check the ROM build on my Ace and found the factory backup on samfirmware. I read up on Odin at the same time, so I'm feeling better about going that route if needs be. I was just wondering if there might have been a quicker and less radical way to uninstall CWM and unroot... and still have have the phone at 99% of what it was rather than start from scratch.
Guess the only reason I'd go back would be to send it in for some reason under warranty. But who knows, at that point there's the chance it might be beyond flashing to factory.
Thanks for confirming that CWM and rooting will be gone if I ever flash back to factory. It's been a crash course in the past few days, going from knowing zip about all this to just staring to get a handle on it all.

Devce status: MODIFIED

hi guys!
i recently flashed uk stock lfb rom over my orange stock rom, i rooted my s3 using chainfire cf-root 6.4 and i used triangle away to reset the counter.
everything went smooth, counter shows 0, but in settings/about device/status/ device status is now MODIFIED and not NORMAL as it used to be.
even if the counter is reset to 0, isn't this an obious proof for servicing companies that phone has been modified and loosin warranty? is any way to go back to normal? i searched the forum and i didn't find a solution.
thank you!
flash stock rom and your phone will show that normal status again. samsung will never know what you did to the poor phone. double check that you don't have supersu or superuser app or else something bad might happen

i already tried that, but a lot of apps didn't start corect, phone became very unstable and unusable. i even couldn't check if the status went back to normal. could it be because the original version seems to be an earlier release compared to lfb release?
i flashed stock rom, ALE8 to be exact, a few days ago, after having a few problems with wanam 1.9. the status changed to normal after flashing. i use desktop odin to flash. after flashing wanam 2.0 the status changed to modified. tried triangle away, but the status still doesn't change to normal even though flash counter has been succesfully reset.
The full steps are: (in that order)
- Triangle Away
- Flash Stock ROM
- Flash correct CSC / Modem (optional, not required)
- Factory-reset the phone
Reset the flashcounter, update rom and after boot do a facory reset.
flash stock rom, wipe everything, doesn't mean that the phone back to normal. for example, i always set my line to wcdma only. after flash any rom, reset everything, that setting still wcdma only. the only way to have absolutely format, is change csc code. it's truly format back to stock. but, be warning, you will lose everything, backup 1st.
so the trick is factory reset? good to know! i will not try it btw, because i need a working phone for this 2 months. OP, is your question answered now?
I don't know yet
I have to try that first, but i can't do IT right now. I hope that after flashing my original orange rom the phone will be stabile enough to perform a factory reset.
Thank you guys for your suggestion.

Hey dude. I'd just stick with it
even if you should have to send it in, they'll pretty much only look at the counter (If possible) and if that is not possible, then they'll JTAG it; meaning that EVERY tiny piece of information on that phone is gonna be wiped... Just make sure you don't send it in, just because of a small SIM failure. (Because that's caused by bad radios/basebands). Only send it in, if it's proper bricked, and they'll not no a thing (I've done this loads of times, they haven't noticed a thing to date )
yep, factory reset did the trick.
as i said, after flashing original orange rom over lfb rom the phone became unstable.
i booted into mini cwm that came original with the phone and there is an option to do a factory reset, et voila, no more modified status.
thank you guys!
No problem hit thanks button )
I have a brand new s3 from orange which has not been rooted or anything and the device status shows as modified. i have used the Samsung GS3 Int ToolKit and odin to flash an unsecure boot image so i could back up my phone which i still havent yet as i need to root and install busy box. i have not rooted the phone or changed the rom so why does it say device status modified. I did a factory reset but it still shows as modified.
I will be flashing the rom once i know how to backup the orange rom and data. I want to remove the modified status incase i want to return the phone to orange so they can give me an unbranded phone in the first place.

If you flashed an insecure kernel, you did modify the state of the device. Are you saying that it showed as modified out of the box?
same problem
I have never rooted my device, never intended to either. However my device status appears as modified. While I personally feel there arent many glitches in my phone (s3), I'm worried i wont be able to upgrade to jellybean when the update comes out.
Any help?
Which firmware/ROM are you using? Are you rooted?
I'm asking this cause if you bought it second-hand the previous owner could have modified it.

would having this status affect OTA updates?
Yep, it generally means the phone is running a custom rom/recovery and is rooted. OTA updates only work on non rooted stock recovery roms... However this doesn't mean you can't update through ODIN...

I don't think so. As long as you're on an official ROM it doesn't matter if you're rooted or not.

Thanks, I realised that later on and was just about to re-edit the post. Im sure it didn't say modified when out of the box. Orange won't replace the mobile as they say all their phones are branded and the replacement would be branded anyway. Im gonna flash with unbranded software as i dont want orange bloatware. Just need to know how to back up this useless orange rom and then i can flash!

Yep as long as i've read you can download as long as your on official ROM. You might lose your root but you can just re-root again.

I can get to the factory reset. seems to only clear the data. is there away to re-load the old firmware/OS or a custom ROM. I have another SM-T337 that works perfect can i cloane that one to the other on......what are my options.......thanks
I just leave this here just in case I need to remember this site again .
https://samfrew.com/search?query=SM-T337V
what is this supposed to mean ?
As I said...don't you worry about it.
And while not worrying it, you might as well just flash it with the stock...
(good site, somehow hard to remember for me)

1. Use SamFirm to get the Stock ROM for your phone
2. Use Odin to flash the Stock ROM found
