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 a USB JIG to enter DL mode
Do you get an exclamation mark next to a pc?

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.......

Thank you so much!! I wasn't able to get a usb jig but managed to get it online with a quick delivery. It was my first time using a usb jig but it's too simple. I've a working phone with JB in it.
Thanks 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.

what can I do (hardware bricked phone :()

Well, after saving a long time, I finally got my s3 on amazon.com, when I opened it, it was new and beautiful, I powered it up, inserted my sim, and the phone freezed, after that I waited 2 minutes, and pulled out the battery, and tried to power it up again, but it got stuck at the yellow triangle saying to put it in download mode and use kies, I looked in the forum and found an Odin tutorial , downloaded all the neccessary tools, left the phone plugged to my USB port in download mode doing nothing, and went out fifteen minutes, when i came back decided to flash a new working rom onto my phone i founded the telephone completely dead, not responding to any key combination or cable connection to my pc, i thought it was the battery , charged it on my brothers phone and the phone was still dead,(i tested the battery for voltage and it delivered 3.7 v and 1500 maH, all correct and optimal values, I searched again and tried with a USB jig, trying to get into recovery mode, and it did not work either (the usb jig was allright, because it worked on my brothers phone, and on a friends Galaxy SII , so i do not know what else to do, and i ended posting here. What can i do? i will send it back to warranty , but maybe i can solve it first , Thanks!
Hardware bricked you can do nothing .
USB Jig is not for recovery mode .
If you have flashed your warranty may be void .
But also possible its SDS .
Sudden Death .

Do you have latest Samsung drivers installed? And also try to run Odin as administrator if you're using Windows.

[Q] I think I might have hard bricked..

I can't boot into recovery or download mode, I have no charging screen, just a red LED. I bought a USB jig cause I saw someone revive a hardbricked S3 with it, but I can't manage to get it to work..I might just not be using it right though. Is there no chance of revival? I was trying to update from 4.1 to 4.2 when the phone just shut off, then it wouldn't turn back on.
this might a problem because of battery (did you tried to flash with lower than 40% battery? )
And i hope you flashed the correct version of i9300 .
Remove your phone battery ,put battery on ,insert the usb jig and should prompt you directly to download mode , if not ,then you need a new motherboard

Galaxy S2 dead

Hello everyone
I have a few years old Galaxy S2 9100 that had the original firmware and rooted. The battery was about 20% and it restarted by itself and was stuck on the Samsung logo. I tried to make it work by no hope. I then tried to enter recovery mode but it gave me an error. I then entered download mode and tried to reflash original firmware through Odin but it was stuck at around 40%. I did it again and same thing happened. After that it was completely dead and won't turn on. I can't enter download or recovery mode. When I connect to computer, it gives nothing. When I plug it into the charger, it becomes hot on the top but nothing appears. Any help is highly appreciated. Thanks
Well

Try this:
- Take the battery out
- Fully Charge the battery via any battery charging device
- Place the battery back
And check if it's turning on -=-=-=-=-=-
If yes:
- Check if PC recognizes device i.e. USB port is working now or not
- Go to download mode if it's working and do the odin flashing with fresh files and right settings
- And if it's due to the odin flashing prob from your side, try sideloading custom rom and flash it.
If no:
- Go to service centre
Well, this is just me, maybe wait for other comments too. :angel:
Try this:
Find a way to fully recharge the battery. Then, reboot into recovery regardless if it's stock or custom and wipe data completely. Then reboot. It will take sometime but the phone should reboot to factory default. Be patient! If this fails, you need not worry. Just repost here ok

Thanks all for your input. Currently it does not go into recovery. Do you think if the battery is full charged it will?
Try charging the battery. What have you got to lose?

Actually I went to a phone shop and tried a new battery which usually contains some charge and it did not help. I will leave it overnight in the charger and see. Thxs
Try other battery...or try usb jig.
You might want to try a USB jig. It is like a usb flash drive. Its job is to put your phone into download mode. You can order it from amazon for about 3 bucks

I also had the same problem. The USB jig resolved it in 2 seconds

Was it exactly the same problem as mine? I mean dead phone with no response whatsoever?
I tried the USB jig and did not help. Maybe it needs the battery to be fully charged?

Samsung j6 soft brick problem

Hi guys, I have a samsung galaxy j600fn/ds, tryed to flash twrp, something went wrong and now I'm locked on the ''Samsung'' logo screen
I guess it is brick, though I'm totally stuck at the screen, the phone won't even turn off, so I don't know how to acces download mode to install stock firmware.. anyone can be of help?
EDIT: solved.. of course the solution was just to wait for the battery to be completley depleted, I just got scared there not beeing able to do anything
Wait-
So you just let your phone in bootloop all night (?), then you charge it without turning it on,
waited till 30%, and then you put it in download mode and installed the firmwere?
Does it really work? 'cause I tried to do that before, and the bootloop stopped. I tought I ended up into an hard brick.
I pressed powen and tried to put the phone into download mode, but nothing.
I put the usb on my pc, and odin was actually reading it, so I tried again and again to get into the download mode.
Afret 30 minutes, i pressed power again, (and finally) the boorloop restarted.
Well um.. the phone now is probably at 60%.. I hope it wont stop again, and I hope this method will work.
