Need help rooting/recovering - AT&T Samsung Galaxy S II SGH-I777

I tried rooting the phone by flashing an insecure kernel. Now I can't get the phone into download mode. Odin/Kies recognizes the phone in MTP, and windows recognized the phone under debugging/file transfer mode... but Odin won't see the phone under debug. Also, my home key now operates as the back key with no key working as home. I flashed the XWKDD insecure kernel as directed by one of the walk throughs.
Before I flashed anything I couldn't get the phone into download mode using the three button combo, but I was able to do it simply by having the phone in download mode and plugging in the USB cable.
How should I proceed? I assume I need to flash to stock and try again with another kernel, but I can't find that as an option. Is there another way to go into download mode? Please help. I still have the same captivate that I bought on release date and I would love to have a fully functional phone for the first time in over a year!
Thanks in advance!

Download mode, this has ALWAYS worked for me:
Pull battery
Reinsert battery
DO NOT HIT POWER
Hold VolUp + VolDn
Insert USB cable into phone
Phone should power up right into download mode.
Edit: Stock kernel was posted 5-10 minutes ago in dev section BTW.

Thanks! Now I'm able to get into download mode consistently... but I'm getting an error in Odin... "Can't open the serial(COM) port.". Going to try resetting the computer and phone. Unfortunately I'm just enough of a noob at this to know how to get myself into interesting predicaments haha. I had all kinds of fun playing with issues with Cognition before I finally switched over to cm7.
*edit*
I'm back to stock now, thanks again! I don't know why I didn't think to do that, that's how I used to get into download mode on my cappy. Now if only I could get the drivers to work with my phone in debugging mode...

[Q] So... I bricked my phone =/

I'm stuck at the Vibrant boot screen, and when I try and plug it in the USB and user adb devices, it doesn't recognize it. I've tried Droid Explorer, and I believe my Vibrant is hardware locked.
Any ideas? Sorry to make another thread but I couldn't find a solution to anyone with this problem.
What did you do to it?
Search around the forum, there is a post talking about getting into download mode with hardware lock phones.
If you are able to get into download mode you can use ODIN to install stock ROM again.
Something incredibly stupid, I tried flashing a custom kernel on the stock ROM.
Yeah that's all I've been doing. I've read all the threads I can find about how to get into download mode with a locked Vibrant, but no luck =[.
Launch Odin
Plug in USB to PC not the Phone
Insure Phone is off
Hold down Vol +/-
Plug in cable
Hold down +/- about a second
Walla you are in Download and should see a yellow triangle
Have you tried turning off your phone and turning it on holding down the Vol +/- and power and entering Recovery mode?
From there you could flash a nandroid backup if you made one that is. Sometimes I get lucky if its in the regular recovery and use the Re-do package option and sometimes I get it up and running.
Of course it just depends on where you are in your flash and what your phone will allow you to do.
Tried that oh so many times, and it just wouldn't budge.
At first I was actually able to run ADB commands... and before I had read more about it, I booted it into recovery (instead of dl mode fml) and wiped cache/user. I already tried reflashing zips to see if CW would start up so I could restore my nandroid backup I had made.
Anyways, now ADB doesn't even recognize the phone. And I tried to install the drivers on my laptop to see if that would do the trick, but I'm still stuck.
Edit: I just tried to use the method you gave in your first post again and I just get the battery charging screen. Thanks for trying to help though, I appreciate it.

Phone ! PC-Can't get past this (bricked?)

Was attempting to flash one of the leaked samsung roms using ODIN. Only way we were able to get phone into download mode as using the ADB command line with ADB Reboot Download.
Odin saw it, we started the process. Seemed to be working, but it got stuck with a black screen for over an hour (when I flashed my Vibrant process to all of 10 minutes). We thought the phone just didn't reset, so we unplugged it and hit the power button...and the dreaded cell phone...!...PC screen came up.
I've tried all manner of trying to get into recovery/download mode with no avail. Again, we tried EVERY combination of button presses to get INTO download mode initially, but only the ADB command line method worked.
Now we cannot get past this screen. Any ideas???
SCREWED!!!! Call TMO and have them send you a new one. Nothing you can do if it is hardware locked.
That's what I was afraid of. That is what he is going to do, glad mine didn't have that happen as that ROM has my Vibrant working like it should (GPS works now!!)
I wonder if having to force download mode via ADB was an indication that this phone would have a problem with flashing anything to it??
Never had a brick as many times as I fooled with my Dash and G1. Guess it was bound to happen sometime.
if the battery pull method won't get you into download mode you're likely screwed...
- Make sure USB cable is connected to PC, but disconnected from phone
- pull battery
- hold down VOL+UP & VOL+DOWN and do not release
- insert battery
- insert USB cable into phone
If after a few seconds download mode appears, release VOL keys...and....you've got download mode...if not, it's safe to say your gonna replace the phone..
If that works, I'd also recommend using Odin3 v1.30 instead of v1.00 that most people use. Available here... http://forum.xda-developers.com/showthread.php?t=790026
Wishing you the best of luck!
Try runnin odin with NO pit or pda file. Ive been at that screen like 100 times, let me kniw what it does
You mean start ODIN and just plug in the phone?

That' not a big deal dude, you don't need a jig, just do us all a favor and re-edit your post without using caps - cause it's pretty f***** annoying.
Remove battery>plug USB cable in PC and in phone>hold down Vol up and Vol down together>putt battery back in>should go in to DL mode, once there, let go of the volume buttons, unplug USB from phone, open ODIN, plug USB back in, ODIN should pick it up -good to go again.
Happened to me lots of times.
If above pattern doesn't work, try the same thing, but hold down on/off button as well, along with Volumes. One way or the other has to work....

dear friend i have tried both ways many times and i could not get to download mode and all what i see is an image of phone and computer connected with dots.
so if you have any other solution please let me know.
thanks again..............
There is a guy on Team Whiskey's site that sells JIGs for like $5 if you can't make one yourself. There is also a guide on making them in my Noob Guide (signature). I would like to TW's site, but it's down right now.
Think that's your only bet right now.
I've been there plenty of times where you're at. You CAN get into DL mode using the hardware buttons, you just have try different ways. I NEVER had a problem (from where you're at) getting there, you have to make sure you (critical part) pull battery out, then plug usb back in phone, press both volumes down together, as you keep holding them, put the battery back in. It should go into DL mode. Try a variety of ways, but always pull the battery out then back in while holding a combination of buttons down. USB has to be plugged in as well for it to work.
This is my second vibrant so far, and was always able to get it there....yours works the same.

[Q] Help My phone is in a Boot loop and I cannot access Download mode!

I totally messed up while trying to install the Simple Honey ROM. I was trying out an ICS rom for a lil while then decided to go back to GB....I ODIN'd back to Eclair, then flashed this rom without flashing GB Bootloader. Now, i am stuck in a bootloop and i cannot get into download mode!!! There are times where I almost get into download mode but a rainbow appears and then it goes into Kernel panic upload mode. The only thing I have not tried yet is using a USB Jig because I have just bought one and it is shipping in the mail. Is there any other way to get it into to download mode? I cannot post in the dev forum because I don't have enough post. Please someone assist me in fixing this issue.
I have tried the following.
1. Install Samsung USB Drivers.
2. Power off the Phone.
3. Pull the Battery.
4. Plug USB cable into Phone.
5. Plug USB cable into PC.
6. Press and Hold: Volume UP + Volume DOWN + Power, all at the same time.
7. Re-insert the battery.
8. The phone will power now, when the screen starts a cycle of going to a BLACK screen, release ONLY the POWER button.
Tried the following with odin:
As for download mode;
1. pull the battery,
2. put it back in;
3. then, with the phone still off, plug your usb into the computer,
4. turn on odin3,
5. hold the center of the volume buttons,
6. plug the usb to the phone while holding the volume botton
tried holding both volumes without a battery then put the battery in and while still holding plug into usb to see if odin showed a yellow com button. Rainbow occurred and kernel panic upload mode appears.
If odin does detect my phone, the longest it will detect my phone for is around 30 seconds then it will either reboot or go into kernel panic upload mode.
cannot try this posted by Raymond PJR post #9492 p950 on the simple honey thread because I cannot get it into download mode
The bootlooping probably has nothing to do with the GB Bootloaders, but is a known issue that is resolved by immediately flahsing Bullet then back to Talon if you want. So, get the Bullet .tar, start Odin on your PC, get into download mode, connect to your pc and flash Bullet. Then if you want to be able to see what is going on in recovery, consider flahsing the GB Bootloaders. Some say they can still make out the menus under the rainbows, but I don't know. I just went ahead and flashed them. READ, READ, READ, every OP before flahsing, (GB Bootloaders OP, Bullet OP, and if you've never used Odin, the OP of any thread you read on instructions. And watch any related videos on YouTube!
Bootloaders: http://forum.xda-developers.com/show....php?t=1117990
Bullet Kernels: http://rootzwiki.com/topic/639-kerne...es-edt6242011/
also tried this because I could not get download mode or recovery mode. So I tried this trick through odin but it still did not get it into recovery mode after this.

[Q] Soft Brick?

Hello All,
First, let me say how much I've enjoyed reading this Forum and how much I LOVED my TMobile Samsung Vibrant 3G. While it worked for a long time running Froyo 2.2 with a Bionix Next-Gen V2 ROM, it was fantastic, but lately the microphone had been dying (I sounded more and more muffled no matter what I did). So I flashed up to ICS and installed Chimera to see if that might help. While the phone ran beautifully except for several apps that were rather wonky, I was getting more and more muffled.
So the other day I decided to restore my Nandroid backup, however when I flashed back I got stuck on the Vibrant boot screen. No matter what I do, I can't seem to get to Recovery.
How do I get back to Recovery from this? I have never used Odin, the only time I've ever hooked the phone up to the computer was when I originally flashed from Eclair to Froyo many moons ago. So please let me know if I'm missing something.
Any assistance would be greatly appreciated!
You made a mistake when you tried to restore a 2.2 based backup from ICS base ROM. Now you must Odin to stock, its not that hard. First you will need to download the Odin program. I'm assuming you have device drivers on your PC but double check. Next you need 2 files, the 512 pit and jfd firmware file. Once you have those files you need to get in download mode.
I will link a thread with files and directions. http://forum.xda-developers.com/showthread.php?p=9375927

OK I installed Odin and the necessary files and drivers, I plugged in the phone, but when I try to turn it on into Download Mode the Vibrant doesn't respond. There's just the little spinning light in the center of the screen. Odin doesn't recognize the phone either.
Anything else I can do?
Odin won't recognize unless you are in DL mode. I linked a video, I know it says captivate. Don't worry about the mod etc just follow it to get in download mode.

OK watched the video, but 2 things:
-when I try to boot into Recovery it gets stuck on the Vibrant Samsung initial splash screen and never moves, even when holding down the 3 buttons;
-this video assumes I can access the phone to install the fix or anything else. I can't, it just stays stuck in the splash screen;
-I tried holding down the 3 buttons and simultaneously plugging in the USB cable, and still nothing but the splash screen;
-is there any way to turn on the device while hooked into the computer so Odin or something else can use the necessary files to turn it on and make it accessible?
Thanks all for your patience and advice, it's much appreciated. I LOVE this little phone and really want to heal her!
Hi,
I think you have tried to go to recovery mode using 3 button combo. But in order to use ODIN device has to be in DOWNLOAD MODE which can be done using following steps
1)start off with phone turned off
2)press down volume up, and volume down at same time, and never let go until you get into download mode. DON'T touch the power button
3) while holding down both volume buttons get your usb cable which is connected to your computer
4)plug in the usb cable into your phone, while you still hold down both up/down volume buttons at same time. Don't touch the power button.
5)As soon as you plug your usb cable into your phone, the phone will instantly go into Download mode.
6)You may now release the volume buttons

NOTE: here is a link I found. Just take a look http://www.ithinkdiff.com/how-to-access-download-and-recovery-mode-in-samsung-vibrant/
OK we are trying to get download mode not recovery. Your phone must be off for download mode. If it flashes vibrant screen you have gone to far and something is wrong. I specifically said pay no attention to the mod in video. Regardless I think you might need a jig to get in download mode.
I approve this message.
OK, noob error (smacks head), I kept saying Recovery Mode when what I needed was DL Mode, my sincerest apologies.
I got into DL Mode finally by holding down the Volume buttons (not the Power button), then plugging in the USB cable. The Vibrant promptly went into DL mode. Odin recognized the phone and off we went. It's now back to Stock Eclair (yuck).
So next question: am I rooted or do I have to do that all over again? And if so, what's the fastest way to do it so I can flash to the ROMs I knew and loved?
Lastly, a great big THANK YOU to samsgun357 & haarsh for all your assistance, you guys ROCK! :good:
No you are not rooted after using Odin to go back to stock. Glad you got it buddy! Now use this guide to get root and cwm recovery. Option b is probably what you want

Glad you are successfully ODINed and you are in perfect position to make things BETTER
Still the device is not rooted as samsgun357 said. but no worries it is a simple process to get rooted and go ahead. I will post an video and hope it will also ease up your task
tc and its a pleasure to help you
Happy Flashing :good:
Yep, got it rooted and flashed Cyanogen7, then flashed up to an ICS ROM (started with Chimera but it's a tad wonky so flashed over to Euphoria, we'll see how that goes).
That said, the microphone is still sounding very muffled, so I think it's a hardware issue. I was due for an upgrade anyway so I picked up the Samsung 4G Blaze (nice since the Vibrant I had was the 3G). So right now I'm just having fun exploring Android on the Vibrant while I read up on how to root and improve the Blaze.
I will miss this little phone though, it was light and super fast and agile, perfectly sized, especially compared to the mini-tablets coming out lately like the Samsung SIII and LG L9 or HTC One. I prefer smaller phones, so the Blaze fits the bill right now even though it's heavier than my old Vibrant.
Thanks again for everyone's assistance, VERY much appreciated! :good:

I'm having the same problem w/ my phone (see img).
I can't get out of the little loading pinwheel.
I've tried all the prescribed methods in this thread.

Sorry, also, I can't get to DL or the splash page. When I turn the phone on, it goes directly to the spinning pinwheel.

Download mode IS what you need to use Odin a get back to stock.
The above post shows the button combo for DL mode and recovery based on which bootloaders you're running (thanks haarsh). If you haven't flashed GB boots, you have froyo boots.
Now make sure you have the correct Odin files and drivers on your PC.
The goal here is to get power to the phone, while holding button combo, from the PC.
Do a battery pull/replace. Plug USB into computer
While holding your button combo (see above) plug the phone in.
Hopefully you see DL mode
Also try pulling battery, plug USB in PC and phone
While holding button combo, pop the battery back in.
This can be tricky sometimes so don't give up.
OK. Let me backup and give you more info.
So sorry...
I rooted, but was unable to download ROM manager from the Store (im assuming bc it was running Froyo).
I was able to get CMW to install via update.zip. Once installed the phone was going directly into recovery when asked (3 button method). It would go into the Anroid recovery, first and then from continually installing CMW, go into CMW.
From there i installed a CM10 nightly.
Install went fine, but no mobile data connection. I went back to CMW and restored the original ROM, rebooted and am stuck w/ the pinwheel.
I can't get into to download mode AT ALL. I've tried the various button methods with no luck.
From what I did, I can assume that 2.1 IS installed on the phone.
Thoughts?
Thank you so much for the help.
Well the issue you have was caused by going back to a 2.1 or 2.2 build from cm10 through cwm. You should have used Odin to get back to stock.
If you can't get in DL mode manually you will need to buy a DL jig. You can get them from www.mobiletechvideos.com also from amazon I think. You can also make one yourself, just search USB download jig, you should find it.
