bootloader error - Galaxy S II Q&A, Help & Troubleshooting

I flashed wrong bootloader in my sgs2, and now it wont even started, the usb is disabled and not working plz help

Can you get into download mode (turn phone off; then hold volume down & home button, while you're holding these down press the power button until it boots into download mode) ?
If you can't, there's a very slim chance a jig might get you into download mode. Search for "Samsung Galaxy S2 jig" on eBay, or have a look at the thread in the General section where people are offering to let people near them use their jigs. Might be someone living near you who has a jig/might let you use theirs.
If the jig doesn't work, you'll need to send it back to your carrier/Samsung for repair, but they more than likely won't fix it under warranty. Alternatively, you could send it to a 3rd party for a JTAG repair which will probably be cheaper for you than Samsung fixing it.
But before you start worrying about that, try getting into download mode then try a jig.

Follow what mistah said above, download the correct bootloader for your phone, and follow the instructions above to get into recovery and flash the boot loader tar file in the boot loader section of Odin, your computer may not recognise the USB as a drive but Odin should recognize it as a com port, it can be done I did it no so long ago if you get stuck give me a shout and I'll talk you through it

Odin, not oden.
Heimdall.
But considering you've probably hosed your device with the wrong bootloader, your only form of rescue is likely to be JTAG.

thx u r right have to jtag

[Q] Phone (!) PC Brick

This time i'm sure its bricked...
I was installing the Voodoo lag fix for 2.2 JP6 firmware and it failed... Then the phone started with the Phone (!) PC icon...
I'm unable to get into Download mode.
I'm goig to use this factoidz.com/how-to-unbrick-your-samsung-vibrant-galaxy-s/] Method to try and get it back to dl mode then i'll reflash with my Jp6 and just be happy with a good 2.2 rom and no lag fix.
Anyone ever recovered from this issue before? Could you please explain how?
Thank you,
Jay
someone should start selling those Jigs lol.
I have that pc-(!)-phone icon once but I just send it to TMO.
Try getting to download mode using ODIN !
Make sure phone is fully of then start odin and hold VOL UP + DOWN buttons and insert the USB cable into Galaxy S and Downloading screen should comes up !
Always works for me after bad ROM flashes ...

They do. I saw them on ebay for $20
ODIN won't with if you can't get into dl mode. If this doesn't work, one of the resistor jigs most likely will. My phone was hardware locked when first tried messing with it.

If you follow this^^^ exactly it will work this will get you into download mode after that you need to flash to Froyo ~~~That does not Brick! rom with odin. Right after you flash that get back into download mode open odin first then with the phone ( power the phone off give it a min, hold down the volume up and down keys, now insert the usb cord BAM download mode) flash back to whatever rom you want. Or don't learn how to to fix it and send it to tmo and tell them your phone just bricked itself somehow
Here i go!
That 2.2 was awesome! Time to stop messing with it if i get it back up...
Got'er done y'all! Thanks!

Bricked Vibrant

Hi everyone, i need ur help please. I have a t-mobile vibrant (sgh-t959). I tried the CM on it. After installing the su kernel, it bricked. Now it keeps rebooting with the samsung galaxy s gt-I9000 screen (the vibrant screen no longer comes up). I can't even get to download mode by pressing vol up + vol down + pwr buttons. Please help me. I m kinda desperate ...

Although I didn't have the exact same problem, I had a very similar problem. The above link will give you more details about the problem I was having and how I solved it (thanks to click1's suggestion).
I could not get into download mode no matter what sequence of keys I pressed and my phone hanged on the "samsung vibrant" screen. IF your phone is detected by Odin or the computer when you plug it in (doesn't have to be in download mode and your computer doesn't have to be able to show you the usb drives - just as long as there is a confirmation that a usb was connected is enough), then Android SDK will help you force the phone into download mode.
If this doesn't work, your next bet is to physically make a JIG for it:
forum.xda-developers.com/showthread.php?t=819551
From what I have read, this last one physically forces the phone to go into download mode by using the 5th pin on the MicroUSB key.
I know how you feel - I just got my fixed last night and my problem seemed very unique, I wish I could offer more help but I hope these will work for you.
Thank you very much. It finally came back to life. Feel so much better now!
downnload mode, I hold both volume buttons in and connect the usb and it I get into download mode everytime

No problem, I'm glad that solved your problem. I'll see if I can put this solution on the Noob guide so others can see it easily before they resort to making a JIG.

the newer vibrants are hardware locked so you can't get into download mode that way. This is why you have to use the SDK to do it.

Does this mean if the sdk will not recognize that the device is connected then i have to make this JIG Thing? because my phone is stuck at the connect phone to pc screen.

Yes, make it or buy one. I know who sells them for a VERY reasonable price. If you're interested Pm me for more info.
okay found a solution for now, my issue was related to ROM manager with the SD card, kept getting wrong MD5 Sum!! Really pissed me off about this since I was running through ODIN correctly,
Solution...
Updated the rom with Eugene froyo!! This brought me out of boot looping and now I have a rom on my phone so I can go back to the basics of flashing I hope, I am going to give it a try to see what happens

No...being the noob that I am, I'm constantly finding new ways to brick my phone. So tonight, I bricked it with the phone to PC screen. ADB can't detect it and neither can odin. This is FIXABLE, I tried the method here:
http://forum.xda-developers.com/showthread.php?t=771247
Method 3 worked for me. Even if you have a hardware locked phone, I think there is a method around this which involves taking the battery out and putting it back in but I don't remember where I read this in the forums....I know I did read it though, you have to search to find it. Try these before you resort to making the JIG.

Ace Totally Bricked

I usually work with iPhones so Android phones are a new field for me...
I have a friend who rooted his Samsung Galaxy Ace and then installed Android 2.3.4 but he decided to install something as he says that "doubles the ram memory of the device" well as soon as he installed this the phone immediatelly got bricked.
I have it here in my hands and I tried entering RECOVERY, DOWNLOAD mode and it was impossible.
So I tried pressing all the button (Vol+,Vol-, Home and Power) and the device was USB recognized by my PC,installed its own drivers but nothing showed up on the screen. Then I pressed Home and Power and USB sound ran again and from there on the phone does not react to any combination of buttons, taking out the battery or anything and the PC does not see it anymore.
I tried to be as specific as possible cause I really want to help this guy... So If anyone knows what are the possible solutions besides "take it to samsung care center" I'd really appreciate it!
Thansk!
Install KIES from Samsung so you have the drivers for the phone.
Install ODIN and run on your pc so you can flash a stock ROM (you don't need to have KIES running at the same time)
Take the battery out of the phone and connect it to the pc with ODIN running via USB.
If ODIN detects the phone put the battery back in and now you can flash with a stock rom and your phone will now work.
There are instructions on this forum where to find ODIN and how to load a ROM into it ready to flash.
have u tried the USB Jig?

I'd save that for plan B, If it's showing up on a PC it's not bricked.
Bricked = no power, no response, no detect by pc no nothing.

But Can I download any ODIN? Because I've seen through the forum that there are several ODINs for different Samsung Models... besides there are several ODIN versions! So which one do I need to download? Please a little help here cause in the Android field I'm still a noob!
Also as I told you, the first time the PC recognized the phone when I pressed ALL the buttons... but afterwards it does not recognize it anymore... does it have to do anything with that KIES you are just telling me about? Also which KIES should I download?
Thansk!
To me it doesnt wounds like its "Totally Bricked", take the battery out and leave if there for awhile, come back later on and see if you can enter download mode.
If you want you drivers to be installed correctly, download the KIES (2.1 i guess?) and get ODIN to reflash it.

Ok... this is as far as I have come.... The guide for unbricking seems good, there is only one problem. I've already Loaded ODIN with the firmware files and boot, and all those files. But I can NOT, I repeat I can NOT enter DOWNLOAD MODE (Vol-,Home, Power Buttons). I can only enter EMERGENCY DOWNLOAD MODE (Vol+,Vol-, Home and Power Buttons) and the good news is that ODIN is ABLE to recognize it, BUT as soon as I hit star it stays stuck at "<1> setup connection..." Well before you start saying to search forum for solutions, well I did, and I found this thread: http://forum.xda-developers.com/showthread.php?t=1188378
The guy had this same problem and he realized his problem was that he was entering EMERGENCY DOWNLOAD MODE rather than DOWNLOAD MODE. BUT I can NOT enter DOWNLOAD MODE the phone just doesn't enter this mode, only the EMERGENCY DOWNLOAD MODE so what can I do to make ODIN flash my phone!!????? Please help!!

Ok So I finally did it. Bought the USB Jig! From here:

And Guess What! IT DID NOT WORK!!!
This was my last resort and now I don't know what to do! But pay attention the funny thing, AS I mentioned earlier in ALL my posts! Is that the phone is recognized by ODIN but only in EMERGENCY DOWNLOAD MODE (It even says "COM PORT 18") But in this mode ODIN doesn't flash it, I needed DOWNLOAD MODE which was the reason why I bought the USB JIG, but it is not working! Is there a some kind of workaround to get the JIG working? PLEASE I REALLY REALLY need help!!!
Thanks!

[Q] My Sgh i777 can't enter in download mode eighter in recovery mode

Well, my phone cant enter in this modes, but the problem its that also cant enter to the system, i can only see the logo of samsung and then the screen turn off, I dont know what to do, because I cant use the odin because I cant enter in download mode, I dont know if there is a button to hard reset the phone. I was trying to put a rom of ics but i believe that the firmware was wrong for my phone. please help me.
Sounds like you flashed something in Odin that was not for your phone. You probably need to get it J-tagged to get it fixed. Check out mobiletechvideos.com
It's like $50 dollars for the service, they'll J-tag your phone and flash the correct bootloader.

Since the phone will turn on, and initiate the boot process, it should be able to recover it yourself. Jtag is for true hard bricks, which your phone is NOT.
Please give a full description of what led up to your problem. What firmware was on the phone before, what did you attempt to flash, and anything that you can think of that would provide any additional information for trouble shooting. Also, a link to the firmware you tried to flash.

Nobody knows what can I do in that moment?
I put my i777 on download mode by removing the battery and putting it back. Hold the volume button down and connect the USB charger wait for the buttons to flash and disconnect the charger while holding the volume down button. If that doesn't work nothing will.

Try this:
Pull the battery and leave it out.
Hold down volume button and plug in the USB cable. (PC will supply the power)
This should boot the phone into download mode.
If the above works to get into download mode, do the following:
Download the I777 secondary bootloader .tar from the Download Repository. See the link in my signature.
Unplug the phone (to shut off)
Open Odin v1.85 on screen of pc.
Enter download mode as above.
When connected put the secondary bootloader in the PDA slot in Odin and flash.

I just recently got my SGS2 (i777) and decided to root it. Unfortunately I got the root from another site (dumb move) and today the phone went into a reboot loop. I can connect it and get it into download mode, but everytime I try to flash back to the stock rom, or anything else (bootloader) Odin says connection failed, unable to open COM Port. I know it connects because it installs the drivers for the phone. Can someone MUCH smarter that me assist with this one?

can you interrupt the bootloop by trying to get to recovery (holding VOL UP + VOL DOWN + POWER until recovery menu appears) and then go to backup-restore and restore a backup? That's what I would try. IF that does not work, I would reinstall the drivers for andoid on your pc --even though you had them working (presumably) once before. After reinstalling the drivers then odin should (may!) see the phone and work.
good luck

Bootloop and physically broken home button, help?

So I tried to flash clockworkmod recovery to my galaxy s2 and now it's on a bootloop and the home button has been broken for a while so is there any way to fix the bootloop in this situation?
Simple answer.....no.....
You're bootlooping so you need to get into recovery, you need the home button to access recovery.......
Get the home button fixed.....problem solved.
You *might* be able to boot into recovery through ADB.......don't ask me how, I don't know how......but I'm pretty sure that even that won't work if you don't have USB Debugging enabled.......
Sent from my infected_ KitKatted S2.....
I found that I might be able to get to download mode and flash stock rom with odin by using a USB jig. What do you think about that? The phone had USB debugging enabled when this problem started and the phone is rooted. I was earlier able to boot into recovery mode using adb but now I can't because PC won't recognize the phone since it won't boot correctly.
Try it & find out (the jig), but Keith's advice stands; if you do manage to get that done, fix the home button immediately after. You're just asking for the SHTF at some point & you'll end up without a working phone when you most need it (again).
Fixing the button is probably too costly and it's hard to do myself because I believe the screen has to be outfitted to do that. I'll order the jig now and report here if it solved my problem.
I was in a similar situation, tried flashing many roms. No luck.
Until I found this thread: http://forum.xda-developers.com/galaxy-s2/general/guide-t2345831
The "Another option for i9100" did it for me.
Good luck!
Yeah I got the phone working with usb jig. I flashed official rom, that I downloaded from Sammobile, with Odin3.
