Something similar happened to me earlier.. when you where in the backup/restore menu did you select the "restore from external sd card" option? And if you did and it still didn't work I recommend starting over fresh.. go here and this should allow you to do so. Qbking's awesome :good:.. Follow his steps and he'll have back in action in no time.

Sounds like you didn't root and install a custom recovery. If you can get into download mode, you can flash one of the one-click stock rooms and then give it root access after.

[Q] galaxy s3 i747m ROGERS to jelly bean cm10

hey guys
let me start off by saying i am a noob to this site and android in general , ive learnt a lot from my galaxy s2 .
now i got the s3 , ive rooted it .. however i tried to upgrade to 4.1 awhile back . kept getting error .
anyways i want to upgrade to jellybean im sick of waiting like everyone else.
cm10 seems like a good rom , ive read a lot on this forum, could some one tell me what the first step is do i flash cwm first on the rogers stock or do i have to put ATT stock on it
thanks
cheers
Hi!
Welcome to the site! You'll really love the community here!
Here are some simple instructions I found for you: http://www.androidauthority.com/gal...elly-bean-cyanogenmod-10-cm10-preview-104742/
Just make sure you download the latest CWM from here (6.0.1.2 currently): http://download2.clockworkmod.com/recoveries/recovery-clockwork-6.0.1.2-d2att.img
And flash it to your device.
Then follow those steps, wipe/format data partition, as it says there. CAREFUL make sure you download the latest CyanogenMod version from here too, the top one on the list is always newest, latest version came out today actually: http://get.cm/?device=d2att
Let me know how it goes and if you're enjoying it! Tried leaked version of JB on my S3 with Telus in Canada and didn't like the bugs in there...so let me know if the 'CM Finishing Touch' on there is really better than stock!
Michael
thanks man. i will give it a try soon and let you know..
so just i get this straight i can do everything from my rogers stock rom right .. i dont have to download the att stock rom ??

Yup! Start off with CWM Recovery flash, when that's done, transfer file to device (internal sd card) and from the ROGERS stock rom you can do the apply update from zip option in CWM.

Hmm...try ROM Manager free from the Play Store. If not just google around how to install CWM, installed it a while ago so I forgot sorry. But ROM Manager should work.

should i take off auto reboot then take out battery... i remember doing this when i rooted the phone . i think...
oh and for rom manager i cannot find my phone on the list , there isn't any galaxy s3 on it weird?
Hmm...weird. Guess it doesn't support the extra-super-duper-phone yet! Haha!
If you get the SGS3 All-in-one toolkit from here http://forum.xda-developers.com/showthread.php?t=1703488 , you can install CWM from it just make sure you have drivers installed, it can help you with that if you don't have them, and enable USB Debugging.
If that doesn't work, which I think it should, try to use this link a bit. Download the version they have it should be pretty recent.

Oh so now you have CWM? Well as long as you have it, you'll only need it once or twice to erase all data, then install CM and GApps.
Ill try it with the cwm from the superuser one but I remember doing that it said error 9 or something

Quick question, I flashed CWM recovery using the terminal, and I see it when I boot into recovery, but when I go to ROM Manager to flash CM10, it says to flash CWM Recovery, and won't let me access the list. I would've flashed CWM from ROM Manager, but the S3 wasn't on the list of devices. Is there anyway to get around this?

Hi there!
Basically you must first but the CWM ZIP file on your internal sdcard then boot into CWM, from there go to install zip file or something like that, then select from SD Card, find the zip, you're done!
Don't forget to do a factory reset through CWM before the CM10 update and maybe after too.
Let me how it goes,
Michael
Never liked CWM, I personally love TWRP as a recovery. Go to the app store and download GooManager.

But don't I already have CWM? Or is CWM and CWM Recovery two different things? Where would I get the CWM .zip for my rogers phone? I backed up my phone from recovery mode, does that mean I backed up my current ROM (stock rooted ROM)? And I backed up a few apps using Titanium Backup, if I use factory reset, would all my backups get erased? Thanks for your help!

Hi,
CWM = CWM Recovery; same thing just shorter .
The ZIP file for your rogers phone can be found here: http://get.cm/?device=d2att
Click the one at the top of the list as it is the newest.
Don't worry about the ROM because worst case scenario if you want to downgrade to stock, you can re-download it online and re-root.
For the apps, it depends where your backups are, usually, in TitBak, the backups are stored in /sdcard/TitaniumBackup which will be safe as formatting to factory settings and data partition in CWM doesn't format the internal or external SD Card. But I am not responsable if it does so be careful!

Also, I just got a notification to update SuperUser, which takes me to the Playstore, but on I remember seeing not to update SuperUser on the thread where I was told how to root my phone. So do I update it or not?

You can update it, I don't see what could go wrong because an update will only help fix things if there were bugs you had.
Okay, thanks! I'm going to use this <http://forum.xda-developers.com/showthread.php?t=1587607> guide to flash the cm ROM. But say afterwords, I want to unroot and remove the 'Modified' status of my phone, and return back to the stock ROM like nothing happened, and remove the flash counter. How would I do that?

That would be with Odin you would redownload the Stock ROM for Rogers and then flash it. To reset counter, you can download the app TriangleAway for free from the Play Store and with root, it resets the counter. Then you can unroot.

[Q] Can I return to stock Koodo?

Hey guys/gals,
I recently bought a Koodo Galaxy s2x. After a few weeks I looked online and saw that there were some JB Roms for my phone. I couldn't resist and tried to flash one after rooting. I didn't have many problems with it, but there were some glitches that started to bug me, so I decided to see about going back to stock (I should have done this first I know). So then after hours(many) of searching, the best I could find was a T-Mobile stock Rom I decided to try and flash it (both times via odin). I also read somewhere that I should use darkside superwipe to clear my cache, so I tried that, but ever since that CWM stopped working on my phone. anytime I tried to do any back up or anything it just froze, and I had to hard boot. Finally I just tried flashing T-Mobile stock ICS, and Odin said "Failed". I decided to just unplug my phone, as I thought I already screwed it up, but after rebooting, the T-mobile Rom worked. I don't understand why it works fine if the Flash Failed. Now, I can no longer connect to kies (I'm hoping official JB will be shipped soon!), and I am wondering if I can somehow return to a stock Koodo Rom, and if it will connect to Kies again, as it previously had. I have looked a lot and have not found anything that I fully understand. I'm not overly experienced, which is why I should not have flashed to begin with. This is the closest thread I have found to help me, but I don't fully understand what all I need to do:
"Haven't seen anyone shared this yet.
Here's the KOODO ICS 4.0.4 stock ROM I used CWM to flash to stock after I tried the custom ROM.
h t t p s : / / sourceforge.net/projects/koo...d.zip/download
I also flashed DARKSIDE.SUPER.WIDE before I flashed this or you can used CWM Recovery 6.0.1.2 to wipe system and cache."
Is it possible for me to get back to stock phone? and still connect to Kies? and then possibly upgrade to JB through Kies if Hercules ends up receiving it?
Thanks for any help you can give me. Here is all my current phone info incase this helps:

If your ultimate goal is to get Jellybean on your phone, check the development section of this subforum. There are numerous stable and wonderful JB roms (AOKP Milestone 6, Liquid Smooth, CM10).
To get back to your stock ROM, download it from here: https://sourceforge.net/projects/koo...d.zip/download
Then, go into recovery (NOT odin), and flash the rom.

That link doesn't work, it says cannot find page. Also, my phone is currently not rooted, does it have to be rooted to flash from recovery? if not what do I do to flash from recovery? I know how to get into recovery, but after that do I use 'apply update from external storage'? Do I have to wipe the cache first?
Thanks.
PS: I just want to be able to get back to stock for now. At least until I learn more about flashing Roms. There is still lots for me to learn, like kernels, radios, Nightly's for official Roms, or even how to properly flash a rom without feeling lost. If I know a way to get back to stock comfortably, It will give me more reason to try some other Roms (once I learn how).
Here is a working link to the stock Koodo ROM: http://sourceforge.net/projects/koodostock/files/KOODO_SGH-T989D_Stock_Signed.zip/download
Are you running a custom ROM right now or your stock ROM? If you're running a custom ROM, it should come with root privileges. If you are running the stock ROM, you can just back it up instead of needing to download the zip from sourceforge. This guide will help you get rooted: http://galaxys2root.com/t-mobile-galaxy-s2/how-to-root-icsgb-on-t-mobile-galaxy-s2-sgh-t989/. After rooting, get into recovery mode (if you can't get the button combinations to work, there is an app. called quick boot which reboots you into recovery/bootloader/etc). If you don't have a recovery or it's corrupt, download ROM manager from google play, and choose the 'install clockwork recovery'. Reboot to recovery to make sure it works, then uninstall rom manager (it's been known to cause bugs if you use it for other things - and I'd recommend other recoveries such as TWRP but it's a bit more advanced). From your recovery's screen, there should be a backup option. Make a complete backup and name it something appropriate. To flash a ROM, download it and put it on your storage drive. Reboot to recovery, and go to wipe. Wipe your data (factory reset), and system (only really need to wipe data in most cases, but be safe). To flash the custom ROM now (or flash the default ROM I just linked), there should be an option to 'install zip from sd card' or something similar. Choose that, browse to your ROM and install it. After installing, go to wipe and wipe your cache+dalvik cache, then reboot. There are several beginner guides sticked in the development forum, along with explanation of terms like radio/kernel/nightly/etc.

Thanks a ton... Worked perfectly! I'm hoping it will connect to Kies once again.. I'll let you know if it works.
Unfortunately, I still can't connect to Kies.. It just sits at the Loading status (for like 10-15 mins). But At least I don't have all of the T-mobile apps and stuff anymore!

if this root and ginger bread and has set you want CM10.1 making corresponding step. but it and done the ROM manager but it stays flashing flashes 100% and does not advance d there ...
You should install CM10.1 through CWM, so basically you need to ROOT your phone first.
Please be careful. I have a rooted nitro and was on CM10.1 with Wind Kernel with a lot of apps installed. I had several nandroid backups made with CWM latest version.
Since wind over clocks, my nitro got so unstable (bootloop) that I had to go back to the backup.
However, CWM was not able to restore the backup image.
All of the backups did not work.

Unable to Flash any ROM

Hello all,
I haven't had this issue before, which is odd, because I have been using the same rooting techniques/rom/cwm/phone for a while, and former tech support employee. I simply can not install any rom. After it installs, it reboots and either stays on the samsung screen or sits on the samsung screen for a while and then goes back to cwm. I have tried reformatting my sd card. I have successfully used odin back to 2.1, upgrade to 2.2, root using one click (I have never tried to root on 2.3). Then upgrade cwm to 5.0.2.7 and the problem starts all over again. Any ideas? Please and thank you.

Have you tried using odin to load the pre rooted stock rom found here on the epic4g forum somewhere? From there, you can boot into CWM and install any rom you want. CWM will automatically be upgraded with the rom you install.
Formatting your sd wont do anything for you. I think the problem you are having is trying to install cwm using one click. One of the newer OTA releases over-writes this and puts back the stock sprint recovery.

So I am still having a problem. Today I received my replacement device from Sprint. Exact same issue.
Originally the ROM was installed on my device, and I was getting some force close errors, so I ran "Wipe Data/Factory Reset" and reinstalled the ROM. It just sits on the Samsung logo for a while and then boots back to CWM.
So here we are again.
I ODIN flashed to Android 2.1, OTA update to 2.2, OneClickRootCWM3.1.0.1-EC05.zip to root, install CWM v. 5.0.2.7, and wipe data, wipe cache, wipe dalvik, and install the ROM and stuck on Samsung logo again. I am going to cry. I need my hotspot back and all my custom stuff.
What on earth am I doing wrong?

I know one click has an old (green) version of cwm but I update it via a zip file afterwords. I have tried to install the ROM before updating CWM as well.
I am starting to recall there were different version of Froyo e.g. DK28 and EC05 but I don't understand what my issue is because right now my device is sitting on CWM 5.0.2.7 and it actually goes through the installation procedure it just doesn't boot to it post installation.

[Q] Beginner trying to root/flash new ROM on T989!

Hi all, found my old SGH-T989 and I want to turn this phone into my play phone.
I am new to rooting and all and I don't know which versions of what to use. Everytime I mess up, I have to restore the phone back to stock 2.3.6 then upgrade to 4.1.2 via Kies, then try to root and such.
Problem is... I don't know which ROMs, gapps to use and which cwm to use!!! Seems like every guide out there is outdated because I get stuck in a bootloop every single time I try to flash a ROM or I get Error 7...
Any tips?
I just want 4.4.2 at least on my SGH-T989 What are my options? What are your suggestions?

You need to be on 4.1.2 for this to work. I am bit responsible for what happens. You can get 4.1.2 for Odin from samfirmware.com. Download the latest TWRP from here: http://techerrata.com/file/twrp2/hercules/openrecovery-twrp-2.7.1.0-hercules.tar and flash it in Odin. Your phone should reboot. Boot into recovery by powering off your phone and then holding power and the two volume buttons until you hear two vibrations and then hold just the volume buttons until you see a black screen. Release all buttons. Flash @Chainfire's SuperSU in recovery ( http://download.chainfire.eu/452/SuperSU/UPDATE-SuperSU-v2.02.zip) Wipe cache ald Dalvik and reboot. You should be rooted and able to flash any KitKat ROM. AOSPA is a good choice. It is pretty stable.
Sent from my SGH-T989
I just flashed CarbonROM on my sister's phone this weekend. Rooting is not really required.
My process:
Flash TWRP (this was the most difficult of the entire process. It is still relatively easy though). I used Odin to flash the latest TWRP. TWRP provides odin flashable archives so it is really just a matter of knowing how to flash thing using Odin. This does not require root. The CWM wiki page says that Rooting is not required, nor is it the preferred method when flashing a new rom.
You can use Heimdall, but it is very hit and miss with this phone. Odin is much more "reliable" on the T989. I tried Heimdall, but I ended up having to reset my sister's phone because it flashed the recovery incorrectly.
Download the rom of your choice and its associated gapps package. Put them on your sd card
Boot into recovery. You will need to use TWRP's mechanisms to wipe/factory reset the phone. Then wipe cache and dalvik cache.
Install the zip of the rom and then immediately afterward install the gapps package. I usually wipe the cache and dalvik cache again for good measure at this point, but I understand it is not needed.
Reboot the phone. If all went well, it will take awhile to boot, but you will be sitting at the start screen of a brand new shiny rom.
Set it up and start using it. Most roms already come rooted.
The reason rooting isn't required using this method is because the download mode of the T989 essentially gives you root priviledges.
I've used this process on two T989 phones without any error. If you want to backup your phone, do that in step 3 _before_ you wipe/factory reset your phone.
Usually what I do is just use Odin to flash ClockworkMod then copy the ROMS to the sdcard. Boot into recovery then install zip from SD Card, select ROM. If you use CyanogenMod then just select your device and Google search the cyanogenmod gapps
