[Q] Unroot - Galaxy S II Q&A, Help & Troubleshooting

Hello!
I've tried root my device a couple weeks ago, and I think it's not worthy. I was looking for some ROM that boosts my battery performance but I can't find any.
I've installed Touchwiz 4.5 (the mod from this forum), I'm running a gingerbread 2.3.4, of course I root my phone following the Chainfire process ( http://forum.xda-developers.com/show....php?t=1103399 ) and unsucessfully installed a battery indicator I've do myself in the UOT kitchen.
So I want my tocuhwiz 4.0 back, keeping my gingerbread 2.3.4 (or even installing 2.3.5 , I saw it was released), I also want to remove the exclamation mark that appears everytime I turn my device on, and of course to unroot my device.
I was told that if I resinstall the Stock firmware (touchwiz and gingerbread) I will be able of updating my device via Kies.
So, is there some kind of order? Do I have to do something before something? Will my device be as when I purschase it? Some tips? Do you know where I can find the Stock firmware?
***IMPORTANT***: First time I rooted (I think I was actually not rooting, just installing Gingerbread via Odin) my device was wiped, and it was a pain in the ass to restore my contacts list, my config, and this kind of stuff.
How can I do a backup? Better with CWM or with Titanium Backup (the non-pro version) ??
Thanks in advance!

Don't get too much going with the device if you don't have time for it, it will get you under confusion and irritation.
► You just have to flash a Stock firmware to Unroot and get all those default stuffs, TW 4.0, GB 2.3.3/4 and else.
Follow this thread to get firmwares,

► As long as you are on Stock firmware you will get updates via Kies.
Regards.

Restoring the Stocks firmwares will remove the exclamation mark?
And for the back up?

I don't need any backup for my apps, that's why I don't use anything else other than Kies, and don't know about it.
Yes, restoring a Stock firmware will remove the exclamation mark.
Regards.

[Q] Trouble upgrading from GB to ICS

Hello all XDA users,
Many apologies for the noobish questions, I am new to this forum and this is my first time posting. Although a first time smartphone owner, I decided to be brave and attempt to root and flash my phone, which worked fine under Gingerbread until I wanted to upgrade to ICS. I have a International GT-I9100 SGS2 purchased in Singapore. I rooted it by installing a custom kernel and flashed a new Lite'ning Rom V3.2 with Gingerbread.
In order to upgrade to ICS, I tried through KIES and the "Software Update" function to no avail. I then tried to do so manually but Odin would not complete the process with the original I9100XWLP3 rom I downloaded on this site. I left it running on my computer for 2 hours only to come back home with the progress incomplete.
My questions are:
1) I live in Taiwan now. My other friends who purchased their SGS2 locally here all have gotten ICS through KIES. Am I unable to do this because I purchased it from Singapore and must wait for the Singapore rom to be uploaded? Is there no way for me to flash to the local Taiwanese I9100ZSLPE rom?
2) How long does an ODIN flash take to complete? Should I be more patient and waited longer than 2 hours for it to finish?
3) Does KIES no longer recognize my phone because I rooted it? It always fails to download the driver whenever I plug in my phone. Do I need to unroot to an official ROM such as I9100XWLP3, and then download through KIES to get ICS, or is I9100XWLP3 already packed with ICS?
Again, many apologies if these questions are elementary in nature, and thanks in advance for the help. Attached you will find a picture of my phone's current firmware state.
[1) you must be on a stock rom as your friends had, since you have rooted and installed a custem rom, keis will not recognize your phone. you can flash it from ODIN also, if you really need official update from Kies, you want to flash the same stock ROM your friends had in their mobile at your region...
2) Maximum 5 minit, something wrong with your connection, it is strange finally you got installed after 2 hours waiting...
3) same answer as #1, + you dont need to unroot, mere rooting will not effect Keis update, XWLP3 is an ICS rom
Should I perform a full wipe before upgrading my rom?
Thanks for your response, all the way from Kuwait. I backed up most of my files via Titanium backup. Should I now perform a factory reset before upgrading to ICS? Wouldn't the factory reset also wipe out my Titanium backup, or is this somehow protected? Do I need to transport my backup to my pc first? I tried to backup via kies, but the driver issue prevented my phone from being recognized.

on which firmware are you currently?
it is always good idea to transport to PC your back-up, even wiping and factory reset will not touch your own stuffs on SD card, also while you are flashing a ROM from ODIN and CWM.
also take care when you restore your backup from tintanium, uncheck all the system data, it will mess up your phone, if you had made the backup from a GB Rom, install only user applications.
Your backed up data will be on the SD card a folder named Titanium backup, you only need to download the application titanium backup from market, after rooting your phone.
Edit : sorry I did not notice your picture uploaded, that means your attempt on ODIN did not do anythig and luckly it did not hurt phone too, I think your PC connection or driver is not proper....google more about usage of ODIN....

[Q] Bugs with 2.3.5 official firmware? How to reinstall?

Hi all,
Complete noob question warning, I've searched but not found the answer. I installed the latest official firmware from Samsung using Kies and it appeared to work but the phone is now buggy. It crashes to black screen and drops service, then reconnects to the network and scans the SD card again, and has done this mid call. Is there any way of rolling back or re-installing the firmware without rooting etc? Kies just says the latest firmware is installed.
Thanks
Neil
Odin is the program you need to Flash stock samsung roms, samfirmware is the place where you get them.
Look through the post tutorial on how to use Odin for ace in this very Forum, I don't know if there is a way of flashing the desired firmware with kies.
You don't need root to do it, but its recommended because flashing with Odin WILL WIPE YOUR STUFF, so having root and a backup with Titanium backup is very handy.
Pd: root it, I don't know anyone who's sorry after rooting.
You could go into recovery Mode.
Reboot and hold the middle button.
Then wipe data factory settings (It will deleted everything) Exept SD. and its like it was installed for the first time.

I9100 LPJ possible brick?.

Hello I am from Argentina, desperately need help.
I rooted my SGSII ICS 4.0.3 phone with CF Root LPJ everything went as expected. Odines PASS! and all but when my phone reboots it just turns off after logo screen with triangle.
I can get into recovery and download mode but that is all.
What should I do?
Might commit suicide if there is no fix.
Flash stock rom.
You can find it at sammobile.com.

If you can get into recovery and download mode, you are only softbricked. It could be worse.
Please be more precise, I lack experience but I will understand.
Which stock ROM should I flash now?
Because I got a downloaded I9100UHLPS_I9100AROLP4_ARO but it is not LPJ.
I also managed to find Kernel_I9100XXLPJ at intratech. Would flashing this kernel fix it? Could it possibly mess my recovery mode and brick my phone?
Flash the same ROM again using Odin, do not flash the wrong kernel.
ARO is a good ROM, just flash it again, it will boot, then root with the cfroot for that ROM later.
What do you mean by the SAME rom? I got this problem flashing a CF-Root kernel not an entire ROM.
The ROM I had before was ICS 4.0.3 which I upgraded officially via Kies.
Should I flash ICS 4.0.3 UHLPS that is for my region? I9100UHLPS_I9100AROLP4_ARO
I'm pretty sure that's what Atifsh meant, yes.
Thank you all! Thanks given with the button for all!!!
I flashed stock ICS 4.0.3 for my country downloaded from sammobile.com and the phone recovered with no trouble! I got my soft bricked SGSII working again!
Is there anything I need to wipe now to make sure there is no crazy leftover from the CF-Root boot fail?
If it's working fine, then probably not. I mean, you could always backup your contacts, call logs, SMS, etc and your apps with Titanium, do a factory reset, and then restore contacts, call logs, sms and user apps/data only (do not restore system apps or data).
But if it's working fine now, I don't see the point.
I want you to do two things for me tho.
First, get kTool either from Google Play (it's free) or from Hellcat's thread on here. Then backup your EFS. Keep one copy on your external SD card in your phone, and keep another copy on your PC. Then I want you to do a Nandroid backup in CWRecovery.
That way if anything does ever go wrong, you should be able to recover/get up and running again easily without losing your stuff. For example, if your phone ever borked & you had to send it in for warranty service/replacement, you could restore that backup when you get your phone back/a new phone.
Do a backup at least once a week and certainly every single time before you flash a new kernel/rom or if you make major changes to your system.
I am afraid of doing anything with this phone now. First experience = soft brick.
Damn I almost die. Now I need to find a way to get out of this stock 4.0.3 ICS because it is ramming through my battery and is as slow as a potatoe.
4.0.4 is eMMC hard-brick possibly if I wipe after flashing.
Now I feel like an expert.
I also tried flashing cf root today and it softbricked my phone. Weird.... next time I try to root my phone, I wont be using cf root.
Which Kernel was yours? Leave it here logged for future brickers.
Mine was LPJ

Updating rooted stock ics to JB

I'm pretty new to android so sorry for newbie question.
When I bought my phone it came rooted on what I guess is stock rom etc, 4.0.4 version.
I tried doing OTA update but it gives me some error when it restarts and get into that state, don't remember, turned update off with titanium backup.
So for a while now I've been meaning to update to some nice new rom but I haven't found anything I really like so I want to just update my version to stock JB but now I have no idea how. Can anyone point me to right thread/guide or give me tips how to do it and how not to lose any files (apps, sms, settings etc etc), that's what putting me off from ROMs the most, losing all the stuff and setting it up back again.

As it seems you are not 100% aware of rooting, and your phone came rooted, maybe try to read first in the general section all the basic how-to documentations (e.g. how to root, how to unroot, how to flash a rom etc.). This will give you the background knowledge that you need.
After you got that knowledge and understand it, you can flash a stock Samsung JB rom via Odin or Mobile Odin Pro. The rom itself you can get on sammobile.com, here on XDA or via checkfus.
I hope it helps

I'm back on stock rom. Stock recovery. Device 'normal' - easy unroot?

Here's the deal, my S3 has become faulty through no fault of my own. In the past I've run off custom ROM's, recovers, kernels but for a few month's I've been running on stock. A week ago (updated to 4.1.2 when it arrived for O2 UK punters) it started randomly freezing and the only way to fix it was to battery pull. It's been getting worse to the point I was doing a battery pull a hundred times a day. Believing the issue was with 4.1.2 I decided to reflash a custom ROM via CWM which made no difference.
So... It needs to be sent away for repair. I've done an emergency firmware recovery via KIES to get back to stock ROM. I used the S3 toolkit V7 to flash insecure boot, root, TriangleAway. Flashed stock boot, run TriangleAway and then done a factory reset via stock recovery.
I'm at the following stage:
Stock download mode shows official binary and basically the way a brand new never modified S3 would look... No counters.
Settings > About > Device Status shows as 'Normal' and not 'Modified'
The only thing is that I still have SuperSU installed and root apps are working... I want to get rid of this as easily as I can because quite honestly I've given myself a headache with all the back and forth. Can I simply uninstall SuperSU and I'm root-free in a way the repair center can't tell (at least easily anyway)?
