Help! I messed up cwm recovery and now cant recover.

I have a Koodo Samsung Galaxy 2x sgh-t989d. running ICS 404 .I have been attempting to root and run a custom mod.CM9
I installed cwm recovery and was able to root, but made a mistake and I dont believe cwm recovery was installed correctly as I was not properly in download mode when I ran odin.
Was able to achieve root, but phone had odd quirk that it would hang on shut down. Had to remove battery.
I installed cm9 but it hung on boot screen animation so i restored but the hang on shut off remained. I then attempted to reinstall CWM recovery again using odin. thinking it didnt install correctly the first time....bad idea
Result: now when I try to access CWM recovery the lines are double spaced and I cant do anything but reboot.
Is there a way to repair the cwm recovery or flash my phone back to stock?
I am a total noob and hope this is the right place for this and would very much appreciate any help I can get.

If you're rooted you can download ROM Manager from Play, it will flash CWM for you.

Thanks for the response. Unfortunately No I had tried to restore to factory because of the hanging on shutdown so I am stuck with the phone unrooted. I can access the CWM recovery folders via the sd card, so its really a matter of fixing the CWM install without root.
I have noticed that there is a koodo stock signed zip for my phone on this site which i have downloaded. Is there a way to flash that onto the phone bypassing CWM.
My phone is still operational and so I am a little afraid of making it worse.

If you can get your phone in download mode and connect to odin the you should be able to restore back to stock rom/recovery and perhaps try the process again..

Yes, I can still get into download mode and hook to odin.
Oddly I installed CWM the first time with odin, in recovery mode I believe, and it installed with an error but it worked.
Reinstalling CWM using odin in download mode is what messed up CWM in the first place, so I was a little afraid to try it again..
I clicked pda and pointed towards recovery.tar.md5 as per instructions that I cant link to yet.
so your saying I should try it again?

Thanks for your timet guys, How do I use odin to get back to stock? I know how to use CWM to do it.

this is for soft bricked, but it's exactly the same process.

Happy flashing!
Side note: make sure you run odin as admin, less likely to get errors. And i don't know much about koodo but i would assume that you would need their stock tar file for all this to work

I don't know if there is an odin flashable stock koodo rom in the development thread yet. You could need that to do it..
However if you are having problems with cwm there is an odin flashable twrp in the dev thread.. Once you install that you can flash superuser and root your phone.. Or even go back to cwm if you choose to

It doesn't use .tar files and neither does cwm I think what you are referring too is .zip files..
Unless specified you can flash anything in this forum with twrp. Some roms require cwm but once you have a working recovery on your phone you will easily be able to switch from one to the other

Yes it should work.. after you have twrp you can flash the stock koodo rom or any other rom for the T989/D or the Skyrocket but for the Skyrocket you will need the rotation fix that can be found by searching this forum

Yes you need download mode to connect to odin..
Before you go further I just wanna clarify one thing.. Is it cwm on your device that is causing problems or are you just unrooted?.. Because if you are just unrooted then flashing a rooted rom will fix that

So I googled it and supposedly bootloader is recovery mode , not download or odin mode in other words up and down plus start button. Is this right when I installed CWM with odin it was supposed to be in download mode??

CWM is the problem if I boot into recovery mode the menu displays, but is double spaced and unresponsive as if its not loading correctly.
I am trying to get around not having a working version of cwm installed.
Now I am confused why the install instructions for TWRP say enter bootloader mode with odin ???? thanks for helping me here rymanh

You must be in download mode to use odin.. Otherwise it won't detect your phone...Open odin then Hold Vol down + power the release power once your phone vibrates then connect it to your computer with usb.. Then you should be connected

Ok so I installed TWRP in odin mode as suggested and it worked. Now if I enter bootloader or recovery mode TWRP runs first hurdle cleared. so I will try and flash the new rom now.

Device / Update Software?

I have two t-mobile galaxy s3. when I go to Settings / About Device one of them has Baseband version T999UVLH2 and when I do Software Update it says that it is up to date. The other one is Baseband version T999UVLG1. When I do Sofware Update it says it's not up to date, and downloads update, and then tells me to reboot but after rebooting it fails to update it, and so it reverts back.
What could be the problem that it can't update it - might it be that I rooted the device and I have put the clockworkmod reocvery?

Yes, that's the problem. You have to have stock recovery to update.
Why not just flash a stock rooted Rom, since you have cwm?

How would I flash a stock ROM, using odin? Where would I find the stock ROM? And can I still remain rooted?
Sorry for these basic questions, I am very new to smart phone and android.

Aerowinder, thanks for your reply.
Rooting - I have rooted the phone. That is was not problem. It worked after rooting. It is after the Restore that it is having the problem.
What am I suppose to do
Reset to factory default? I can't do that cause I can't get to settings. In fact I cant get to anything.

Its hard to say, I rooted my phone successfully, then using Odin i tried to flash a rom using a guide i found now Im stuck with this.
I was hopeing to put lighting rom on or something "fast"

So after you rooted it did you boot it up and it worked? What kind of file was the rom that you were trying to flash using odin? You should install a custom recovery, I prefer twrp and it's very easy to install. And what is this lighting rom? Never heard of it
And what guide did you follow to flash a rom in odin?

You may need to try and use odin to put the stock firmware back on and root it again. I don't think you can flash zip files using odin. You use a custom recovery. Search YouTube on how to root your phone and install a recovery. If I understand you right, you rooted it and immediately tried to install a zip file using odin which you can't do.

Then search on how to install a custom recovery, how to make a backup, and how to flash a new rom. There are plenty of directions or there and resources to help. And YouTube really helps.

Use motochopper, it only takes around two to three minutes total, and it leaves you with stock recovery in case you need to go back for waranty purposes, motochopper also does not trip the flash counter, or change the system binary to custom. besides that with the T999L you dont need a custom recovery as the stock recovery has adb sideload support( see Edit at the Bottom For further citation), you just wont be flashing any custom roms until we get some odin roms built, personally I wouldn't flash any custom rom until DocHoliday77 has a true stock odin built, and that won't be until we can get our hands on the stock firmware, which won't happen until the T999L gets an update or at least until sammy releases the firmware, which is pretty much the same time.
EDIT:
after modding a few system files, and getting stuck in a boot loop @ the T-Mobile splash screen, i have found that in fact you don't need a custom recovery for anything but flashing custom Roms/Kernels, the stock recovery not only supports the new Adb Sideload function, the dept of adb support seems to be full adb support all the way down to shell support as i was able to use the following to delete the modded system files and get my device back and running from the recovery menu (no options selected)
adb devices
adb shell
su
rm /system/framework/multiwindow.jar
rm /system/framework/multiwindow.odex
i was allowed to use the rm function of the shell to delete the two files i added to the system/framework folder.

Yes/no if you flash a custom rom you will have to flash a custom recovery to do so, which means you will lose your stock recovery, Docholiday77 is currently working on making all the data we pulled from my T999L compatible with odin, which once its done you won't have to worry, but if you flash custom recovery, custom rom at this stage, you will be essentially locked out of your warranty until we have everything ready for odin, also we just pulled all the info for rom development just about a week ago so I doubt anyone has really had the time, or resources to build a custom rom specifically for the T999L which means you will be flashing at the risk of paid Samsung factory repair if it soft bricks, I'm not sure but I think doc has enough on a rom now to help you out if you brick with cwm or twrp, and with the stock adb sideload support you might be able to push the stock recovery we pulled but you should definitely ask doc for specifics as to what he has to help you if something doesn't go right with a custom rom.

CM added 'asserts' to the updater script that checks what version of firmware you are running. Older firmware was becoming buggy forcing him to do this. Since the t999l is so new it just hasn't been added to be allowed.
You can edit it so it either has your build in the script, or remove the checks all together.
I can tell you how in a bit if no one else does.

Ive made a downgrade that brings you from the 4.3 ota to 4.1.1. the downgrade works but it has the 4.3 bootloader. just flash it via odin, then set it up and then you wont have sound or signal. to get that you must flash the modem file and voila it works. if you want toot just flash chainfires root and then flash recovery via odin. i am currently using this downgrade now with working everything. credit goes to santij07 fro his helpful thread

re: flashing modem
It have the 4.3 modem (MJB). Do I still need to do this, as in, flashing your aforementioned file?

Hey there,
I clicked on the link that you provided (not for the files, but for the thread). I noticed on *that* thread, it was for i747M. Is this/your thread exclusively for i747? I don't want to chance it and brick my device due to a variant mess-up.
Thanks for publishing this info. =)

The link is if the i747m but I used the same process just with the i747 files.

And I only flashed the modem because I wasn't getting network/sound

From the threads I have been reading, NO, you can not unlock using this.
This procedure will allow you to downgrade your ROM to 4.1.1 while leaving you on the 4.3 bootloader. To unlock using the free method you must be on completely stock 4.1.1. Completely stock, including the bootloader, which would be LK3 for the i747, I believe.

no you may not be able to unlock as unlocking would result in a bootloader issue

Why don't you give it a try and let us know? I think as long as you installed the 4.1.1 modem, you will be able to unlock you phone.

i wasn't able to. i actually traded my s3 for a s3 running 4.1.2 and on that one i just downgraded and then succesfully unlocked that one. sadly i don't have either anymore because the one running 4.1.2 was having speaker issues. i now have a vivid and wish i wouldn't of traded lol.

Have any of you guys tried the downgrade and be successful

I was able to downgrade from 4.3 to 4.1.1. I do have a few questions though...
1. S3ModedRom.tar: Is it for the I747 or I747m?
2. Modem file: Is it flashed through TWRP or CWM?
3. How do I go back to 4.3?
Also...for those wondering if you can FREE UNLOCK: NO. I get only a blank service menu
Input on the above questions will be greatly appreciated. Especially the 3rd question

All of these files are for i747 only and modem is flashed via recovery of your choice

Any ideas on going back to 4.3? Im currently downloading Samsung Kies. Any objections to that?

Followed the directions from a rooted 4.3 install and everything worked flawlessly. Thanks!!!
