Can't enter download mode - Galaxy S II Q&A, Help & Troubleshooting

Hey guys,
I tried upgrade to ICS via Kies and the upgrade failed and the phone stopped rebooting. So, I tried to do a recovery via Odin but instead of clicking the PDA button and flashing, I click the Bootloader button and flahed. Now I can't enter the download mode and the phone just keeps rebooting. Is there anything I can do to get into the download mode?
Thanks

Might be a chance that a jig could work. If not, JTAG or Samsung service center.

Thanks
I guess it's time to upgrade to the SIII then....

messing wiv the bootloaders is dangerous i think ,phone needs service center now...

If you’ve hard bricked your Galaxy S2 (and can’t get into download mode) or you want to reset the ODIN download counter (so no one will no you’ve rooted your Galaxy S2), or you just simply
want to remove the i9100 splash screen, you can make a USB jig to solve all your problems.

Actually, a usb jig won't recover a hard bricked device. His device does boot up so it's not a hard brick and there may be a chance.

The device sounds fine, just seems like you're not getting the button combo done quick enough or correctly. Pull the battery first, if it boots into a loop instantly, hold the combo while inserting battery.

using a jig will be a good idea

I should mention that it only starts booting up but never actually goes past the boot up screen. The blue bar stops almost at the end and doesn't go any further.

So, I got a usbjig today and was able to enter the download mode but all attempts to flash through Odin have failed...
Any suggestions?

Without seeing the log from Odin (you could always upload a screenshot; but it probably won't make a lot of difference), hard to say definitively. But being a betting man I'd wager the NAND is completely stuffed therefore service centre job.

Guide: How to fix a bricked SGSII from failed flash, no recovery & no usb recogntion
Now Fixed. - Thanks: Below is the guide to how I broke and fixed it with a little help from my XDA Friends. Maybe the MODS could sticky it as a unbrick guide to go alongside the rest?
So I was flashing a ROM through Odin as per the instructions on this thread http://forum.xda-developers.com/showthread.php?t=1075278
The flash failed and when I restarted my phone I was left with the following:
1)No Access to Recovery Mode through Vol Up + Home + Power
2)Access to Download Mode through Vol Dwn + Home + Power
3)PC would recognise a device was connected on any USB port but kies or Odin Could not detect the phone
4)when phone started or attempted to be put into rec mode just a splash screen saying firmware upgrade failed and a picture of a phone and pc with a yellow warning triangle.
The Cure:
1)Uninistal and Re-Install Kies and Samsung Mobile Device Driver
2)Pureley by accident left my phone connected on flash screen of death through the process and on loading ODIN it connected perfectly right away
3)Set PDA to ROM and flashed.
4)Reflashed as per normal routine again due to boot loop this time in download mode.
5)Factory Reset via Recovery Mode to force CSC update to match ROM
6)*When it arrives use USB jig to re-set flash counter to 0*
Step 2 is not advised as goes against what all the instructions say, please try download mode before this method I don't know if it was just luck I didn't further mess up the phone, but to be honest bar screwing my IMEI it couldn't get much worse! And as I said I found it by accident and it worked. Don't know if anyone has an explanation. From the message on the screen and what I read on Kies ref the emergency recovery I think this is a kind of emergency download mode for when stuff goes wrong as it hints kies can fix it from this screen.
I tried to flash the 02 2.3.5 file from the carrier branded thread, followed all instructions. File was a .tar.md5 i left as is as per instructions.
the flash failed when the phone powers up i get upgrade failed, I can get to download mode but odin doesn't recognise the phone as being connected ive tried multiple usb ports
kies also wont recognise it
i cant access recovery mode
is there any way back?
ive read most of the other posts but don't seem to be getting anywhere other than fustrated!
In kies there's an option to install drivers, try that first and see if it'll find the phone again.
kies
no joy that root, the pc knows its there as every port i plug into it wants to install drivers for device and does so
Remove Samsung Kies from phone and reinstall it and try again .
jje
Cheers will report back, what i don't get is why i cant get to recovery mode would make things easier! Can a jig do this? If i try i just get the failed update screen
I also get same. Screeb when plugged into charger does thos mean its not even charging?

Service Centre .

DAMN
I really wish I saw this 2 weeks ago
Its stuck in the warranty repair centre, I dont expect it to be fixed, so will try this soon when it comes back !
Lol i spent ages reading multiple posts about bricked phones nothing seemed to be working do asked, someone suggested the kies reinstall, then by accident i deviated slightly from instructions in terms of not disconnecting phone and leaving it on brick screen and it happened to work
Alot of people flame for posters asking previous questions but these guys were really helpful to me.
Ask and xda will provide

this just happened to me..luckily sprint gave me a new phone after 2 days for no charge at all..
Odin was not recognizing my phone... than I followed your instructions and unninstaled kies and samsung usb drivers.
turned usb debbuging mode ON...
turn off phone
put the phone in download mode (hold volUP, home, power)
AND WHEN I INSTALLED KIES WITH THE USB PLUGGED IN THE PHONE, WINDOWS INSTALLED THE DRIVERS AND I FLASHED THE FIRMWARE I WANNED WITH ODIN
MANNY THANKS
Glad it worked hopefully this will get sticky

On that screen, the phone is effectively in Download Mode already.
Just connect Odin and flash away, did it on my phone a lot of times already (I sometimes forcefully enable this screen manually - don't ask why - and always flashed directely from there.)
Thanks for that i didnt realise till after I'd flashed that this was still download mode, i was still in flappy panic "dude i bust my phone " mode. Still trying to find out why windows ****s up the drivers when the flash bins out

[Q] Unbrickable?

Hello!
I just had the LG Optimus 2X. The phone is close to unbrickable because of NVFlash. Now i have the Galaxy S3.
Is ODIN roughly the same as NVFlash? Making our S3 unbrickable? I miss the flashing roms etc. like i did with the O2X. But i want to be absolutely sure.
Yeah if you get a brick just go into download mode by holding volume down, home and power together and flash what you want with Odin.
If your phone has a corrupt bootloader you can use a jig (usb-plug) to revive and put it into download mode, so yea it's pretty safe.
Of course if you wanted you might be able to hardbrick it anyway, someone might come up with a hardware-based solution such as S2's unbrickable mod.
So even a hardbrick is possible to unbrick. USB Jig from ebay and im all set to go? Sounds good! Thanks guys!

No, no no
Don't get terminology confused.
A hard brick is unrecoverable by the user!
Only a Jtag service or Samsung service centre can revive the device. Normally the NAND r/w function is corrupted and the phone cannot power on, into download mode or recovery.
A soft brick is where the device is stuck in kernel panic mode, boot loop, or boot screen etc. This is recoverable by the user by entering download mode or recovery to flash firmware.
The USB jig (may) force the device onto download mode where other methods fail.
Still got 2 from my SGS2 days

[Q] galaxy 5 I5500 briked

Hello apparently I bricked my Rom while I tried to reinstall cm 7 or 9 I cant remember from the recovery on clockwork mod I had backup done of that. But then suddenly the phone randomly decided to turn off in the middle of operation. Then the phone wont turn on and if it turns on by some miracle then It just stays at Samsung logo or PC does not recognize it by usb. So I thought that trip to service place would fix it cause i totally bricked the **** out of it lol. Anyways I got told that repair costs 95 eur and that the phone has water damage. Now keep in mind that I keep my phones in dry place and handle them with care in rainy conditions or so. So it is not had any water damage. What impresses me is that they didnt even take it apart. So now im stuck with my bricked phone again and nothing to do. So I was quessing of any specialist could tell me how could I do the unpricking by myself. (Not a noob on tech part) I can sometimes after removing battery and stuff get it in charging mode or download mode but it happens at random.
Maybe u could try soft unbrick ( I think its called so...) The program on the PC will recognize ur phone and it will unbrick ur g5:thumbup:
But please tell me: does the g5 turn on (is it showing any live?)
Sent from my GT-S5360 using xda premium
Well it depends. Sometimes it turns on sometimes it wont sometimes it will start downloading usb drivers while connected to usb and sometimes wont. It just does what it wants but when it turns on its frozen on samsung logo.
Can you get to Odin mode (Yellow triangle)? If you can, try going back to stock. You can get the firmwares at sammobiles.com. Make sure you download the correct firmware. If not working, try flashing ClockworkMod and flash a signed CyanogenMod .zip file. But my problem now, I cant go back to stock. Seems like Odin flashed the stock correctly, but Im stuck at glowing Samsung logo.
Try flashing again?
Yes! Try Odin if the yellow triangle appears. If u cannot get into download mode with button combination try an USB JIG which worked for me like a charm
Odin is the best Option
Sent from my GT-I5500 using xda premium
I reflashed the ROM from samfirmwares but I have the same problem. The phone is stuck in a boot loop after stopping and freezing for a bit at the Samsung sign
Okay. Now when you turn on your phone normally (power button), youll see the glowing samsung logo over and over again right. And it seems to go on until battery empty (I think). Try flashing ClockworkMod instead and see if it boots ClockworkMod. I revived my phone this way, but not able to get to stock.
why don't you go to you're local service?

S2 GT-I9100G dead, completely dead!

Hello folks,
I've a friend who's not a Technical person, however, he tried what he shouldn't have and now he has a totally dead S2.
The problems:
1. Phone doesn't switch on, nor does it goes to download or recovery mode - I tried it all.
2. When I connect a charger or usb - It does start showing the battery icon and while connected to the cable, if I turn it on it stays at the Samsung logo forever.
3. Since I don't know how to even get it to download mode, I'm unable to go any further.
What he did:
1. Trying to upgrade to JB, I think he messed up with the kernel by uploading one which may not be compatible as I've heard S2 has different variants. (He loaded Siyah 4.2)
2. Before doing this, he had connected to ODIN and was trying to load the official JB file but it always got stuck on one of the steps and that's when his phone got a bit sick - it would show "Please connect to KIES and try a recovery" kind of message. And this led him to do Step 1, which he shouldn't have.
I read a lot of posts, tried a lot of things but the phone never goes to download mode. And I've no clue how to try anything else?
So experts, I need your help here and I want to know if this phone will start at all? Can we somehow get it to work? If not at home, can the people at Samsung flash it or something?
Please help. Lots of thanks already!

try this method
if u have any mini usb cable cut it and peel of the skin and short the the 4th and 5th pin with 300k resistor or 100k*3 resistor and connect to mobile u will directly goto the download mode remove this pin and connect pc in odin mode and flash first with ics rom and if it is success and then try jelly bean try good luck
I have the same problem.
Today i tried fixing a bricked galaxy s2(yellow triangle with exclamation mark on boot) by reinstalling the stock firmware with odin and a pit file.
During the install i got stuck at NAND write start.So i took the battery out to get out of download mode and put it back in.When i tried going to download mode,it wouldn't start,charge,boot,anything!it's like it's completly dead.
Is there any other way to go to download mode without using a JIG?

Sorry to say this mate......you shoulda read some threads.....
If you had, you'd have realised.....
1) you start messing with pit files as a LAST resort
2) you NEVER pull a battery during an odin flash
3) when you saw the failure of 'nand write start' there was still the possibility to recover your phone....right up to the point when you pulled the battery.......
So now you have no recovery mode, no download mode and no on screen indication when you plug the charger in.....
Don't bother with the jig.....it's a long shot under the best of circumstances.....
There Is one thing you could try.....
Take the battery out. Press the vol down, power and home keys simultaneously......and WHILE holding the keys.....reinsert the battery....you will probably need help to do it.
It *might* kickstart the phone into download mode.....or.......it might not.
If it fails.....then Samsung warranty repair is realistically your only option.....Don't mention XDA or rooting or custom roms or odin or anything like that. Play dumb....say you were updating with kies, the phone switched off and wouldn't turn on again.......

Thanks for you answer!Will a JTAG work?If i can find one?The phone is off the warranty.
The way I see it is that at the moment, you own a paperweight.....so best to *try* the cheaper options first....jtagging being the cheapest......
If that doesn't sort it....you have 2 options.....
1) replace the mainboard
2) buy an entirely new phone.....
Basically whichever option you choose from now on will have *some* financial cost........

A 3rd option is to buy a 2nd hand phone with maybe a cracked screen,and use the board from that.

[Q] Cold dead hard brick S5830i - what is the last resort?

The story:
Got a phone with some software problems when calling from a spouse. Tried to update the ROM and it bricked.
Status:
endless loop of bootscreen
could enter recovery mode and boot CWR
can not enter download mode
unable to boot system
Tried endless guides and instructions with stock ROM's and firmwares. Some of them installed some didnt - none worked. Still in endless loop.
Gave up yesterday and went to bed to keep trying today.
Now its totally bricked.
- no recovery mode
- no download mode
- no boot screen
- cant connect to PC via USB (Odin wont recoqnize)
The only sign of life - whatever I do it has black screen with backlight on but nothing else.
What can I do? They say that a broken phone is only with hardware problems but could I have f**** up the software so much that its the same?

You can try this guide by @SuperMini to force open Download Mode from odin. Here is the link,
How to unbrick Samsung Galaxy Ace
Make sure to use the key combination of Download Mode for your device as the one mentioned in the guide is for Samsung Galaxy Ace S5830. If that doesn't work, then you can try the USB Jig (not always guaranteed to work). If USB Jig did work, then it will force open the Download Mode so you can flash stock rom back using odin. If USB Jig doesn't work either, then your last option is to consult the Service Center. Do post the result. Hope I Helped

1. make sure you have installed drivers on your computer
2. remove battery > connect phone to computer > press volume buttons and lock key
3. if you get a black screen just press the volume up button.
odin will recognize the device
if this does not work then try multi-formatter
using it, format rfs partition and then install some custom rom.
