[Q] Samsung Galaxy S2 SGH-I777 wont turn on - AT&T Samsung Galaxy S II SGH-I777

I have read similar threads but want to make sure I did not miss anything...
My Samsung Galaxy S2 SGH-I777 device seems to be totally dead:
Pressing and holding power button does nothing
Pressing power and Volume Up and Volume down buttons do not get into download mode
Removing the battery and holding power button for a minute to do s oft reset and drain power did not help
Putting the unit in a freezer bag and into the freezer for an hour did not help
Leaving it charging overnight did not help
Using USB Jig method did not work
Here is the sequence of events, as best as I can recall, that led me to this state:
Device was rooted with CWM recovery installed and Android 3.2.4
I then installed FoxHound PsychoMantis 2 custom ROM so I could try ICS (bad idea for a noob)
I ran into the problem "Unfortunately, Samsung keypad has stopped" and device making it really slowwwwwww!!!
I then tried to go back to the stock version using Heimdall 1.3.2 and heimdall-frontend (build from source for my Ubuntu 11.04) and the XXJVU_heimdall.tar.gz heimdall firmware package. At this point the device was fully charged and I was still able to get into recovery mode but was getting "ERROR: Setting up interface failed!" from heimdall-frontend when flashing.
At some point after this I must have turned power off to get out of download mode and then could never turn the device on after.
I ordered a USB jig from Amazon and tried the USB jig method but that did not make any difference to the problem
Is there any thing else for me to try? If not, is Mobile Tech Videos JTAG service my best bet?
Thank for your help and patience with a noob.

What instructions did u follow to do this operation? I think its interesting people think they'll get more help if they put Noob on the page somewhere. "I'm a noob." I'm gonna try that with the IRS next tax year. "Sorry but I can't file this year.". " why not sir?". "Oh. I'm noob at it.". "Oh **** really?! Nmind then its all good. No need to file."

Make sure your phone not missing its motherboard.

One thing I see wrong is jvu, that's not a firmware for this phone

USB Jig not working is never a good sign....
Looks like you flashed some i9000 firmware. Depending on how far the flash went, you may be bricked to the point of needing a JTAG repair. I suggest MobileTechVideos, they've had good reviews.

[Solved] Samsung Galaxy S2 SGH-I777 wont turn on
I finally decided to take the device back to AT&T as it was under warranty. It turns out the problem was a dead battery! It was a shocker to find out that this device will not turn on if the batter is dead (or not installed) even if the power is plugged in. Can any one explain how this is possible and why Samsung chose such a questionable design? It seems to means that to troubleshoot a dead phone one must have a working spare batter!

I've had some issues if my phone dies I just can't get it back on yet either...
I've found that if I pull the batt plug in the usb put in the batt and go into the 'forced upload mode' (as long as I'm able to still get it that far I can bring it back)
the problem I have is that sometimes it seems like it goes into this mode, and then restarts... after a while i'm able to get it to stay in this mode, and then i believe it is able to charge the battery;
I don't know what the deal is, I tohuhgt that charging while device off was now enabled (I believe before if the device was so dead it couldn't load a kernel it couldn't charge or something like that)
anyway; i thought that was in the kernels maybe it's not maybe i need to use something else, maybe our problems are unrelated -- my best advice ... try to get it into downloader (I have a kindle Fire charger that is 5v 1.8a or so, more than the phone needs but I stick it on there and then fight it off and on for sometimes 2 days...) it's *#$(# annoying I can tell you that -- but it ain't quite bricked ... Good luck broseph.

Vibrant won't do turn on

I tried to upgrade to froyo using the odin method from this thread http://forum.xda-developers.com/showthread.php?t=853950. After everything was successfully done my phone shut off and now it won't turn on. I don't get a battery charge screen or anything. The phone's just blank.....
First, Get the Shipping rom (pit and tar files) so you can ODIN back to stock
Be sure you have the newest version of ODIN
Then remove the battery, plug the USB to the PC.
Now put the battery back.
Press both vol keys (up and down) and hold.
That should get you in Download Mode.
If it does not work, take battery out, unmplug USB.
Put battery back and try again to go into download mode.
Now you put the wrong version of froyo, if your keys maps are changed you may be screwed
If so, good luck! You are gonna need a lot of research to see if you can save it
i think i'm screwed.....nothing is working
If anyone else could help me with this, it would be great. I'm in between a rock and a wall right now with my phone.
you flashed the wrong rom. You didn't know that, did you?

No I didn't know that sadly. Is there anyway I can save my phone?
Hehehehe...I bricked mine yesterday. I disabled voodoo via Voodoo Toggle and waited for Linda to convert. I loaded up Odin and put in my pit & tar for JFD, which I always use, and hit start. I was on Nero v3 going to flash Nero v4 when it came out. I got a Fail part of the way through. The phone won't power on at all.....A popup says Windows can't recognize the device plugged into usb...
I think people are confusing things here and there...if your phone won't power on at all, you can't get help...you can't get into download mode to odin or recover it.
Like mine, for instance, there is no amount of times taking the battery out or doing this or that is gonna fix it..We need to read the post before we try to offer help...IF IT WON'T POWER ON how can people post ways to ODIN or RECOVER...
I'm just sayin....

Well right now I'm simply trying to get the phone to turn on which it won't, I was not asking for help to odin or recover. I was trying to ask if anyone else had this problem and if my phone is totally killed or if there's a possibility that i can save it. But thanks for your 2 cents.
Me too
I had ordered Samsung Vibrant Unlocked from T-Mobile USA around a month back. I am well past the 30 day replacement now.
I Rooted it updated to Axura 2.2.5.9
After all the procedure got completed, I rebooted the phone and now it just won't start at all.
My piece is Hardware Locked wherein I can't get into the Recovery Mode, but can get into the Download Mode. But I am not even able to get into the Download mode now.
It just won't freaking turn on.
If I send it over for repair, as the phone is a rooted one, will I void the warranty ?
Please reply quickly. I am starting to freak out.
OK... I want to be the first to eat my words here!!!!!
I tried one last time...just now
I took everything out and only held the volume keys. I plugged in the USB cable to the PC and then to the phone & put the battery in and BAM!!!!! it came on in Download mode
This way has NEVER worked for me without holding the power button. This phone was in all senses of the word "DEAD". I figured I would give it a try with just the volume keys.

Different Situation
I have a similar problem with my Vibrant.
I reset my battery stats and also disabled VooDoo lagfix, and after i tried to reboot the phone, it froze on the vibrant screen.
I tried using soome of the methods that you guys posted before me, but then after i turn it on it shows an icon that there is a connection problem between the phone and PC.
I CAN turn on the phone, is there a way to just like reset everything? and if so how?
Thanks!

If your phone powers on at all, you should be able to get into DL mode. Follow the instructions on how to revert to stock via ODIN.
In reply to the OP, if you tried the download mode method:
connect phone to usb
pull out battery
hold both volume sticks
put in batttery
and the phone still does not turn on even after multiple tries , well you're a bit screwed. But, Samsung cannot detect if the phone has been rooted if it cannot even turn on. Just tell them the Kies Mini update bricked the phone.
omg leave ur phone on charger for 10 min, pull battery out when hooked up to charger put battery back in , let sit for few min pull battery out hook up phone to computer hold vol up vol down pop battery in , helped ? np this has been answered gazilion times in other threads
btw it takes few try this way to get it back up running so dont stop on first , hey .
If you have the phone!pc problem..connect to odin & see if your showing a COM port .... just flash pit & tar if you do. Without download mode

You're talking about a DIY Jig. A JTAG is completely different. They cost $150-300. You can pay to have a local repair shop jtag it for around $50 or send it to Samsung to repair/replace. I'm still trying to find out how much Samsung would charge for the repair if it's deemed out of warranty.
If your phone refuses to turn on no matter what you do and it gets warm or hot if you leave the battery in it, read on:
I hope my suggestion is not too late. I was in the situation before. I tried everything everyone said here and somewhere else. None of them works.
The reason that those methods don't work because you cannot get to download or recovery mode or even the pc-phone screen since your phone won't turn on. The reason that your phone doesn't turn on because the bootloader has been messed up. A jig will work only if your phone can be turned on somehow.
Three possible solutions:
1. Repair or replace it with T-mobile, or
2. Get someone to repair it with a riff box or other similar tool, or
3. Get the box and fix it yourself (not recommended if you are not familiar with electronic stuff.)
This is the link for the same problem you have; this guy bought the box and has his phone fixed himself. If you live in US, he may do it for you if you have no place to go. It does hurt to ask.

[Q] I messed up please help :)

So I was flashing my phone with odin and I really messed up and accidentally flashed it with the captivate software not the fascinate software the phone would try to turn on and would show the att loading screen and just kept looping to that screen. I tried to put it back in download mode and it wouldnt work so I read that I should let the battery completely die and try again. I did that and now the phone will not power on at all the screen stays black no matter what key combination I press. I tried holding vol+, vol-, and power; I tried vol- and power, i tried both with the cable plugged in before and after a battery pull, and tried them both without it being plugged in before and after a battery pull. the phone is generating some sort of heat so i know the charger is plugged in properly, (i tested the charger with a samsung infuse and it charges fine so i know the charging cable is working properly). So my question is how do i get it back into download mode so I can flash the proper stock software with odin? all help is GREATLY APPRECIATED!!! thank you in advance!

thank you! im willing to do the work and research and figure it out!! i use a mac so i am familiar with Heimdall! Ill try what it says, Ill post my results. thanks again for your direction and willing to help a newbie
So I carefully read that post, I'm using a fully charged battery from my friends epic phone, I can't get the phone into download mode and what is ever more strange is that when I press the power button when the phone is NOT plugged into a usb port the phone will show the "att world phone" splash screen, and it will loop boot that image over and over. However, whenever I plug it into a usb cable hooked up to a laptop the phone will go back to a blank black screen and stay that way. Then I will push any key seuqence and I can't get the phone into download mode for the life of me anyone know another way to get into download mode on a samsung fascinate accidentally flashed with a samsung captivate firmware? Once again all help is greatly appreciated
Actually I realized the microusb cable I was using didnt come with the fascinate and the port on the fascinate is oddly shaped so the cable I was using wasnt truly connected, so what happens now with a solid connection to a microusb cable the phone goes to the black screen and will stay that way regardless of what key combinations I hold down. I can even pull the battery and put it back in all while being plugged into the computer and the screen stays black however, when I unplug the phone from the microusb cable the phone will immediately show the "att world phone" splash screen, and continue to loop boot back to that splash screen. Its very strange, someone please help
The usb pinouts are fascinate specific, are you using the stock samsung cable?
Find the download mode jig. Normal download mode methods won't work for you anymore that you're on att firmware. If you're lucky, you can fix it.
Well, let's review........so far you flashed captivate software onto your fascinate, then you thought putting the battery from the epic in your phone might help......I think the next step is definitely to see if putting a hard shell case for the vibrant on your phone will help. May as well cover the entire galaxy s line.
On a serious note, listen to imnuts' advice. It's your only chance.

That's for putting the phone into download mode, not usage of the Micro USB cable. Yes, the port on the phone side has a specific pinout, but the cable itself doesn't.
Love this site, info abounds... Just saw a thread about manually jumping the pins w/a series of resistors. Common sense, but I'd trust the soldering better than my fingers lol. On a lighter note, I think it was only 3 bad ideas... w/ imnuts and shark, he is in good hands.
hey landshark68, i used the battery from my friends epic because the battery from my fascinate would not charge in my fascinate no matter what, so I had to use another battery to even get the phone to do anything, I'm sure you make a lot of friends assuming that everyone is less intelligent than you

It was a joke about piecing things together from all the different galaxy s phones.
lol sorry man, its just frustrating that i havent been able to use my phone and it makes me sad sorry to take it out on you
Did you try this to get in download mode: " If you can't get into download mode with your phone plugged into your PC, unplug usb from PC and plug it into the wall outlet, and try to put it into download mode there. When It goes into download mode, unplug usb from adapter, plug it into PC and put it into download mode, This does work."
it doesnt go into download mode no matter what ive tried all different key combinations used for any galaxy phone and it just loops the "att world phone" splash screen, has anyone else ever accidentally flashed a phone with the wrong model's software before? or am i the only one that is that silly lol
Imnuts is right. And Landshark, while sarcastic, is both right AND funny. Google captivate download jig, (evidently this works for all galaxy s models) read some, go to radio shack, get a (or some more likely) resistor(s), make sure they add up to 301 kohm (again, verify w/ xda post on building a jig, going on what I read last night) and hope you didn't flash yourself a mini att billboard.
or buy one on amazon. 9.99 search galaxy dongle jig. Good luck, since you get some boot activity, it looks like there is some hope.
There is a good chance the download mode jig will work for you based on what you have said. However, it is your ONLY option and last resort at this point if the other download mode methods have failed.

[Q] Black Screen Brick Vibrant

Hello,
Don't know if this has been asked but I have been looking for it for a while. Cant seem to fine a solution.
I flashed my phone wrong with hemdall now my phone wont turn on. Screen completely black i reboot pulled out the battery everything I can think of can you give me a suggestion. I was thinking about buying a USB Jig.
I'm in the same boat and I bought the Jig. However I think Josh just acts as a middle man on this one and shipping is actually from overseas. But you can find it here. http://mobiletechvideos.mybigcommerce.com/samsung-galaxy-s-download-mode-jig/ I suggest a little extra shipping cost.
However the other suggestion if that is not working (I think I killed my phone) is to have Josh do a Jtag on the phone. You can find that at http://mobiletechvideos.mybigcommerce.com/samsung-vibrant-jtag-brick-repair/
Can you get into download mode? Remove battery, plug usb, press up+down vol buttons and insert battery.
hey i having same problem but i could see the vibrant samsung screen but my phone won't pass that and like you say about the usb cable and then plugging the battery i can do that as well but how can i get my phone back and running another rom!!!

The real solution here i doing a JTAG to your phone or make the Unbrickable MOD (It's very dangerous, a person with Welding and electronic skills must do this).
Another thing you can do is buy a broken Screen phone from Ebay (it more cheaply) and change the motherboard!!
My suggestion would be to continue to try to get into Download mode on the phone. My phone was DEAD no life at all plugged into the wall or PC. I kept trying to get it into download mode and magically after hours of failures, ODIN recognized the device! The phone was still DEAD no life at all on the screen but ODIN had recognized that my device WAS indeed connected. So I continued to flash back to stock and as always with a little patience ODIN was there to save me. The phone automatically rebooted after ODIN was done and BOOM! Good2Go
Goodluck!
^^I'm gonna try that and hopefully with some patience it will work. Otherwise I'm also gonna be ordering a jig, they're not that expensive. My problem is the same as the OP's. My vibrant will just not give any signs of life. I was trying to odin to stock from one cosmics ics RC3.1. Wanted to start on a fresh install for AOKP build 25. But then odin decided to fail on modem.bin. then it just hung and phone turned off, haven't been able to turn it on since. I've spent the last two hours trying to put in different combinations and keys and usb attachments to bring any hints of life, but so far nothing. Bootloader update was not checked on odin so I'm pretty confident that its not due to bootloader mismatch but someone correct me if I'm wrong. Sending it back to samsung or tmobile is very far of an option since I've modified the phone to add FFC. If anyone has any advice or hints it would be greatly appreciated. I'm kind of hating myself and flashing now since I was very happy with the rom that I had and how everything was setup. I just wanted to try something new for fun and this went and blew everything up.
^^I literally held down the buttons > plugged in the cord > put in the battery > and counted in my head the amount of seconds it took the phone to "normally" boot to where I would "normally" let go of the power button to get into Download mode, lol I know it sounds ridiculous but that's how I did it. It helped that I had my sisters working Vibrant right there, I used her phone to get into download mode and timed the process and used that as a baseline for the timing of trying to get the "DEAD" Vibrant into download mode.
If all else fails a JTAG as mentioned should fix your problem fosho!
Goodluck!
Ye I fixed it. One day I did what I had been doing the whole time and it just decided to work. Got into download mode then went back to stock. Our phone is so freaking weird yet I love the damn thing. It really is unbrickable. To anyone in this situation just never give up.

SGH-i777 Not Turning on

Hey everybody. I think this thread is somewhere but I looked and couldnt find any solution for this issue. I have a SGH-i777, rooted and unlocked and all that fun stuff. It was working fine until the other day when I believe the battery was drained all the way (wife's phone, doesn't take care of it). I tried charging it but only thing that would pop up was the battery sign for like 3 seconds and then it would go blank, wouldn't charge. I tried going into download mode and it did so I thought it was just the battery. I bought a battery wall charger and charged it. I then tried to boot the phone but same thing would happen. I tried going into download mode and all it shows is Low battery!! Can't download!! in red. When I plug the phone in to PC or wall, the battery sign pops up and shuts down. Any suggestions of what it could be? Bricked? Motherboard? Battery?
replace the battery..?

It sounds like a problem that I had which ended up being a USB charging port and I was in a battery boot loop and also was not able to get into download mode.first I bought a USB jig which forces you into download mode and the USB charger port which got my phone out of that horrible battery boot loop. And with no experience at all I ended up changing the USB charger port its very easy just look up video on utube.I hope this helps you and here's so pics of the stuff I bought

It could be the charging port, but I forgot to mention that I tried with a different battery after having it on a separate battery wall charger and it still gives me the same issue. Well actually now, the previous battery I had doesn't even let me go into download mode or shows any signs of power. The replacement battery that I am trying does show some sign of life by trying to go into download mode, but giving me the "Battery low!!, Can't Download".

I have fixed this issue by connecting 3AA batteries together on series and placing the positive from the first AA battery on the positive terminal of the phone battery and the negative of the last AA battery to the negative of the phone battery. You are basically charging your phone battery minus any safety precautions. Leave the AA batteries.connected.for about 5 minutes and you should be good to go. Reset battery statistics when the phone has booted and charged correctly.

So I had an extra charging port and I switched them out and yet I have the same problem. I am going to try your way jmgelba, but I don't quite understand how you connected 3 AA batteries in a series and connected the positive of the first and negative of last battery to phone batter? Did you use wires? Do you have a image configuration to show me or a photo?
Thanks
I used soldered wires on the batteries which were in series, giving me 4.5v.

first of all thank you to everyone who has replied.
So I bought a new battery and I believe the batteries that I tried were bad. So I tried flashing it back to stock ics with odin and all works fine, until it tells me "FAIL". I dunno why its not flashing back to stock. I managed to root the phone and it roots and reboots and shows the galaxy logo but then gets stuck. I left it for a while but nothing happened. I tried to flash back to stock once more and it got stuck on odin and I bricked the phone, luckily i had a unbrick usb jig and so I took out battery, plugged it in and it goes directly to download mode and says
"Product name: SGH-I777

So I don't know if that means the official ICS is installed or what. I try flashing it again but same thing happens and it fails. Any help would be appreciated.
Thank You.
P.S I have been looking for Stock Gingerbread, maybe thats why its not flashing, but doubt it. Where can I get it?
Now it also gets stuck on Samsung Galaxy SII logo after reboot

first of all thank you to everyone who has replied.
So I bought a new battery and I believe the batteries that I tried were bad. So I tried flashing it back to stock ics with odin and all works fine, until it tells me "FAIL". I dunno why its not flashing back to stock. I managed to root the phone and it roots and reboots and shows the galaxy logo but then gets stuck. I left it for a while but nothing happened. I tried to flash back to stock once more and it got stuck on odin and I bricked the phone, luckily i had a unbrick usb jig and so I took out battery, plugged it in and it goes directly to download mode and says
"Product name: SGH-I777
Custom Binary Download: No
Current Binary: Samsung Official"

Go to the download repository (link in my sig) and flash the I777UCKH7-CL503881 Stock Binaries. That's stock Gingerbread full install with all the files. You can use the one-click downloader, or use the tar.md5 file with Odin. Let us know if that gets you going.

Thats funny cuz I just came back to reply that I found a solution at
http://forum.xda-developers.com/showthread.php?p=18859438 which is your post and I just noticed that you had replied.
It did work and it is back to stock. Freaking tried everything and your solution worked.
Thank You
Easy Solution
A very Simple Solution:-
I have been seeing the same issue in my sgh-i777, and found an easy alternative.
you just cover the battery output points with a small piece of paper. and put it back in phone to get charge.
This way it will only charge; NOT start /try to start the phone and go into infinite loop of boot.
wait for 15-20 min, pull the paper pieces out and BINGO, your phone turn on!

[Q] USB connection + stock bootloop

Hi Guys I've looked at loads of other related posts for this but nothing seems to be the same as mine, let me try and give you a bit of background on this it wont be perfect as it is my sisters phone and she doesn't know anything. my sister left her original charger at her boyfriends and therefore had to use a cheaper non-stock one she had. Every-time she used it her phone would play up do things like open the car mode and keep rebooting, she didn't think much of it and used it anyway. Her phone died (ran out of battery) one evening and she used the strange charger to charge her phone overnight this however seems to have caused issues since then it wont boot it goes past the Samsung boot screen then the o2 boot screen then just repeats (sounds like a boot loop) note the phone has never been rooted and is still 100% stock.
So this is the issue I figured using ODIN and flashing the stock firmware would fix the issue but I cannot for the life of me get the phone to pick up on ANY computer at all I've tried different charger cables, different computers, Different OS's, cleaning the port and pretty much everything else the internet has currently had to offer. I really am at a loss here I cant use recovery as its not rooted I cant use something like Kies Air or mobile odin as I cant boot into the room and using ODIN is im unable to connect to any computers.
So I guys I'm reaching out to you here what can I do to fix this I really need some advice :laugh:
Thanks in advance.
Say hi to your sister for me.
Oh and her battery must be dead because of the charger.
Usb port could also be busted.
Get another fully charged battery and check it out.

Do you think there is anything else I can try I don't want to jump directly into replacing parts/handset.
If it's a hardware fault, not much while you can do other than change the part. The part itself is cheap, isn't even hard to swap it out
