[Q] Unroot US Cellular GS2 (SCH-R760) - Android Q&A, Help & Troubleshooting

Hi all, I am very new to Android and rooting and really didn't think it would be as much of a hassle as it is. I apologize in advance if this post is in a wrong location.
My problem is basically that I rooted according to this thread:
http://forum.xda-developers.com/showthread.php?t=1531303
and now whenever the phone auto-locks, it reboots. I would be greatful if this could be fixed but I really just want the phone back in working stock order as the US cellular version especially is very unsupported to my knowledge. If it matters, I have done a factory reset since rooting but obviously it is still rooted and the problem persists.
Model: SCH-R760
Android Version: 2.3.6
Broadband Version: S:R760.01 K.FB14
Build #: GINGERBREAD.FB14
Hardware Version: R760.01

I had the same problem. what I did to solve this was Easy as 123...
1. Download USB drivers from Samsung. http://www.samsung.com/us/support/owners/product/SCH-R760IBAUSC?#
2. Download this Simple Upgrade Tool from Samsung. http://www.samsung.com/us/support/owners/product/SCH-R760IBAUSC?#
3. Run Simple Upgrade Tool (and Follow the Instructions). This will bring your Phone back to stock 2.3.6 ROM (Unrooted)
note- This Process is assuming that you installed USCC FB14 Kernal Back on your Phone after using CWM Kernal to Gain Root Access... If Not, Make Sure you Follow the Instructions written and POSTED Clearly By (Props To) sfhub http://forum.xda-developers.com/showpost.php?p=23276856&postcount=3

[Q] Questions about rooting from a very new Android user

First off, I'm completely new to this and wish to root my new sgs2, and I've done some reading on the forum about this but got some questions (or want to confirm what I think I know) before I actually go ahead with the process. I apologize if it's something others have already asked, but I would really hate for anything to happen to what has become my new baby...
I mainly just want root access on my phone as I've come across several apps and what not that required root access.
My phone's status right now:
Android version: 2.3.3
Baseband: I9100XXKG1
Kernel Version: 2.6.35.7-I9100ZSKG2-CL361136 [email protected] #6
Build: GINGERBREAD.ZSKG2
I found (http://forum.xda-developers.com/showthread.php?t=1103399) about CF-Root. It seems like a lot of people recommend this method to root, so I thought I may try it out. Before I do though, I wanted to know:
- Just rooting my phone will not prevent me from receiving any new updates to my phone via Kies, right? (E.g. a new firmware or version comes out in the future...)
- What do I need to do if I wish to unroot in the future?
- For this method, this should be the one I should download and use right? (it's the closest one I found matching my current kernel): CF-Root-SGS2_ZS_OZS_KG2-v4.1-CWM4.zip
Again, sorry for asking what may be pretty simple questions, but I really appreciate everyone's help!
Hi,
You can follow this (http://knowmydroid.com/guide/root-samsung-galaxy-s-2) step by step guide to root your SGS2.
1) Yes, rooting your phone means you cannot use KIES anymore. Its highly not recommended
2) Download any official firmware from SamFirmware.com and flash via ODIN
3) You can flash the KH3 version of CF-Root as well.

Hello,
you will still receive updates via KIES.
Unroot is possible with SuperOneclick. I have not tried so far. Every new firmware overwrites root. So if you root with ODIN and flash the rooted Firmware to the original one, KIES will allow to upgrade.
You could also use ODIA's insecure original kernels and use the ones provided from INTRATECH to have the original back on.
Never tried CF myself.
This phone is practically impossible not to root! Read everything thoroughly and take the dive, see you on the other side

Thanks~
Thanks for all the help! I did take the plunge ... and have no regrets!
I used CF's way, and have flashed back to my original stock kernel afterwards (courtesy of INTRATECH). Everything seems to be happy so far.
And now.. time to have some real fun with the phone
Thanks again everyone!
I also recently rooted with the CF-Root method. Congrats from a fellow HK/Taiwan phone user.

[Q] Greyblurred BELL Atrix 2.2.2 - How Do I Upgrade?

Greetings! I've recently acquired an unwanted Motrola Atrix 4G and I'm wanting to upgrade it to the latest version of Android. Here's the tricky part - it's a Canadian (BELL) phone with an inactive SIM, and I'm not too sure what has actually been installed on it.
As far as I can tell, the previous user has 'Greyblurred' the device (See Here: http://forum.xda-developers.com/showthread.php?t=1070076) and flashed it with the custom SBF linked in the thread.
How would I go about updating the phone to Gingerbread? Is an OTA update possible without bricking it?
I should mention that this is my first smart phone, though I quite familiar with the terminology and it's applications. Just a nudge in the right direction would be fantastic.
Here's the system information, if it's of any help:
Code:
System Version: Version 4.2.1.1.MB860.Retail - Blurred
Model Number: MB860
Android Version: 2.2.2
Baseband Version: N_01.92.00R
Motorola Webtop Version: OSHWT_U1_6.54.0
Kernel Version: 2.6.32.9
[email protected] #1
SMP PREEMPT Thu Apr 28 22:58:25 CST 2011
Build Number: OLYEM_U4_2.1.1 - GreyBlurred
Thank you kindly in advance - any help is appreciated!
So it's been almost a year and I figured I'd give this a bump rather than create a new thread. Does anyone have even a whiff of a suggestion? Thank you kindly, in advance.
Okay, I must say I'm quite surprised. Even after almost a year you still haven't been able to research this on your own?
This forum is crammed with various detailed tutorials and guides, that should be enough to get anyone started...
The most obvious first step would be to determine if the phone shows "Unlocked" while booting and/or has a custom recovery installed.

The phone does not say unlocked. However, it does have CWM installed.
I have read through every tutorial. The issue isn't determining how to get the phone flashed to a newer ROM, it's the fact that it has a unique SBF's on it, and I am unable to receive OTA updates (though that's obvious). I'm wanting to simply upgrade it to the newest version without bricking it.
Since it dealt with flashing an SBF that has since been unsupported, I figured I should ask first, before going ahead and fiddling on my own.
Also, it being a BELL model it all the more frustrating!
(And, I am unable to take it to a BELL service store/send it in etc. since I am in Sweden.)
You have CWM. You have absolutely no need to touch a SBF ever again.
Just flash a ROM through CWM. There is no way to brick the phone that way.
All CWM-flashable ROMs work on all devices.

[Q] Returning phone to stock URGENT HELP

Hey guys,
I have to admit I am not too familiar with phones, roms, rooting, un-rooting etc.
Thing is my friend rooted my girlfriends phone and it has been playing up ever since (2 years)
Today I decided to return the phone to standard because with the current root/rom it will not let me update android from ICS to JB.
I backed up as much stuff as I could and then powered the phone in the basic mode and did a factory reset.
Phone starts up and it still has the old ROM on it only with out all the data apps etc.
I read I could load a stock rom with Jellybean on it to get the phone back to standard.
I have a list of samsung firmware's but my phone is not on the list I would post the link but it won't let me because I am a new user.
Here are my phones details.
Model number - GT-I9100
Android Version 4.0.3
Baseband - I9100XXLPW
Kernal Version - [email protected])
Build number - Lite'ning ROM v3.1
Region - XEN
If I use any of the others will this brick my device? Is there any way around this?
Please help. My girlfriend needs her phone asap!!!
Thanks,
kizbot

[Q] Can my phone's firmware be upgraded in a standard manner?

Hi all,
Fairly new to XDA, however I have used it in the past, to root my Galaxy GT-I9100, and install a custom ROM onto it.
However, I am unsure if I can upgrade it.
My laptop doesn't recognise the phone if plugged in via USB, and after some reading around, I fear it may be the kernel?
I know it may seem newbie, but I just need a little push in the right direction. My phone's details are as follows:
ROM: CheckROM RevoHD V6
Android version: 2.3.6
Baseband (modem?): I9100XXKL1
Kernel: [email protected] #2
I wish to upgrade from gingerbread, due to failures with the Rom (forward facing camera broken)
is it safe for me to follow this guide? http://forum.xda-developers.com/showthread.php?t=2365701
Also, I read on This Thread about the MMC-SUPERBRICK-BUG. Does my current kernel contain that bug or not?
Additional info:
I've used ODIN before
I have CWM manager v3.15 installed
Underneath the CWM manager v3.15, it states current kernel: CF-Root 5.0
Thanks in advance, and let me know if you need any more info.
Will
Upgrade to what; that is the million dollar question; doh.
I wouldnt flash anything if I was in your shoes, but mobile odin is a good app.
Brickbug is activated if you run 4.0.4 stock kernel c/w having the faulty chip.
Just posted this on another thread with a similar question!
I had the same issue when I flashed latest omniROM today, turns out the phone was in USB debugging mode so didn't connect. Go to developer options in settings and check it is not in USB debugging mode!
If you have no developer mode go to settings - about phone and then click lots on build number until it says you are a developer (or something like that), then the developer option will appear.
Hopefully that will fix it for you!

Samsung gave up on that device long ago. Luckily the developers here did not. You should look into upgrading via a custom rom like CyanogenMod.
Basic steps go as follows:
Backup everything and save to the PC
Decide if you want to focus more on stability (JB roms) or cutting edge (KK roms)
Move rom zip you chose to the SD card along with the appropriate Google apps package
Install a custom recovery that will work with the kind of rom you want to install
Boot to recovery, make a backup, wipe everything needed, and install the rom and Gapps
*Probably have to install an updated modem depending on the rom you choose*
Reboot and enjoy
You'll find everything you need in the Epic 4g forums here on XDA. Make sure to peruse the Stickies found in the General forum and Developer forums.
