[Q] any advice? no firmware?

Hello everyone,
I received my cousin's phone asking me to see if I can repair it for him. I've tried turning it on and there is the initial vibrate, and thats it. No sound and no display. Nor do the buytons light up. It's like there is no andriod installed at all lol. I have mangead to get it to boot in hboot but again, there is no display. I don't know but could the screen be dead? Is there any advice that may help fix the phone?
I don't even know what firmware it would be running. All I have managed to do it install the HTC Bootloader while trying to root it.
Thanks all in advance
Simon

Go to hboot --> clean storage
if it not works:
did you rooted? if yes, with clockworkmod installed, you can make a hard reset and install other rom

Hello anmnimo95,
Can you tell me how many times I have to press volume - then power button as ike I said, my screen is completely blank, even on hboot mode. It doesnt look like the screen or the front buttons are powering on but the phone itself seems to power up as it vibrates to say its on.
I don't think this phone is rooted but I can't exactly see it as, like i said, screen seems dead

you have to press volume+power pressed at the same time for 3-5 seconds

sorry, i meant as in the hboot menu. I can get into it but i dont know how many time i need to press vol- to get to that option

right.. found the source of the problem. Decided to dig deep into the phone... LCD digitzer and the LCD screen ribbon cables are broken. Going to replace these in the hope that it will work. FINGERS CROSSED!

Galaxy S II SGH-T989D Soft bricked

Hey guys.
So I got this Galaxy S II SGH-T989D from my friend, he just gave it to me.
Anyways, I think it is soft bricked. When I stick the battery in, it turns on, displays the samsung logo, then says Koodo with a loading bar underneath. Once the loading bar is complete the screen just goes black, and the device will vibrate every 2 seconds.
Don't really know how to reset this.
Any help is appreciated
Thanks!

if you can go download mode please flash a stock firmware for t989d and flash it using odin.. get the stock firmware from samfirmware.com if u wish.. goodluck

Thanks Ill try!

Okay when I try it put it in download mode, it displays the warning screen about installing a new firmware blah blah, and then before I can do anything the screen flashes, I see blue and then it just goes back to a black screen and vibrating.

When all else fails I suggest opening Kies on your computer and selecting "emergency firmware recovery"

Sounds to me like a power button problem, not a firmware problem. Could be wrong, but the black screen and vibrating sound like the tell-tale symptoms. Check this thread out: http://forum.xda-developers.com/showthread.php?t=1931310&highlight=power+button
There are many, many threads about this.

Okay so I took the entire phone apart and removed the power button. I tried booting then, and it still does it.
So it is definitely not a button sticking issue

Same issue
I'm having the exact same issue. I've also disassembled my phone and have ruled out the button issue. All fix guides I've encountered thus far require the "volume up + volume down + power button" boot method which is non-responsive on my phone. It continues to vibrate every two seconds. The furthest I get is have halfway through the Samsung load screen before the screen goes black.

it sounds like it might be a bootloader problem, I can't seem to find the thread right now but I know i just saw it on here that a guy in oregon will reset you bootloaders for $25(you pay for shipping), but there was a few people on there also saying that he had done a great job fixing theres. he works for a shop that repairs mobile devices, you should look through the general and q&a for bootloader issue threads i know its in there somewhere.

[Help] Infinite vibrate boot loop, bricked? please guide me! ><

Hey guys,
I recently installed a new rom but it kept turning off if i take any action so I used Odin and went back to stock unrooted. It was okay for half a day
and it started to shut off randomly as well.
*NOW it's in a constant boot loop. Once I insert the battery it vibrates and turns on by itself and shows the Tmobile logo for a sec and turns off -> vibrate x infite showing black screen
I was told that this could be a "sticky power button, stuck power button" so I opened the housing and used air can, and kinda cleaned and messed around a bit but I dont see how it will fix anything (Suggestions please!) Didn't look like it was sticky or stuck at all @@
I can't get into download / recovery mode because phone just shuts off before I can do anything and vibrates over and over.
Is my phone bricked? or that sticky power button issue? I heard theres not really a simple cure for the stuck power button.... is there?
Does samsung do anything about this even though device is out of warranty? I'm so confused atm >< please share your thoughts and guide me please!

Try

Try holding down the volume up and volume down, then hold down the power button until it vibrates twice then release the power then volume buttons. Not sure if you have tryed this yet but that should boot you into recovery.

I dont think that your phone is bricked. I had the same problem and thought the same thing you have. That maybe it bricked or what not. I tried flashing different roms and that didnt work. I went to a repair shop and I got my power button repairs and I flashed it back to stock 4.1.2 unrooted. It has been working fine for me ever since. You might just need to get yours repaired. Hope this helps.

it's not bricked, this happened to me about a month ago. Your power button is broken most likely and needs to be replaced. I got mine fixed for $40.

Google search is a prerequisite for troubleshooting. Here's a couple links which might help, if it's actually a bad power button.

[Q] Power Button messed up

The power button on my S3 (SGH-i747) is pretty messed up. When i'm not touching it, it decides to register a press and completely messes up everything im doing on the phone. It has such frequent reboots that i can barely boot into recovery. The only way i can actually boot is by holding the phone horizontally with the power button facing down. Is there any fix to this? I'm on CM10.1.0 so would flashing back to stock decrease the sensitivity of this button? Or is it necessary to fix at the shop?
Also i have a cracked screen, so im not sure it would be accepted under the warranty even if it's unrooted.

Hardware failure, repair it or get a new phone
nothing you can do, the flex cable that connect's the button to the board is either busted or shorted

I'm having the same issue.
There's absolutely nothing I can do? I thought maybe if I'd open up the device and tinker with it... maybe I can get it working.

Yes this is quite an annoying problem. If you're having the same problem, are you able to boot into download mode? I can't for some reason.

Something like this you don't want to boot into download mode. What if it resets while you're pushing a file? then your whole phone will be messed up.
I got mine to boot. My method is a bit unorthodox though.... i kept pressing the power button throughout the boot process up until the lock screen. Once it finally loads... i flicked the power button a few times really hard.... it seems to stay in the position but remains extremely sensitive.. as in, i dont even have to press it to turn off the screen.
sucks man... i think this is happening to a lot of power users. I'm literally one week past my warranty.

Yeah i didnt want anything to happen while anything is installing etc. I somehow got into recovery, but it shut down within a second. (thankfully the first option in cwm is reboot, so that saved me). I can't return for warranty because I'm rooted on CM10.1.0, which was why i wanted to attempt unrooting (but that seems impossible at the moment).
http://forum.xda-developers.com/showthread.php?t=1753574
That thread seems to be the solution to our problem, but i feel that if i open it up, something worse will happen. Right now, the phone boots up fine when held horizontally (but shuts down ~2min later) and i can easily backup my data.
One strange thing that i've noticed with this problem that maybe isn't right. Normally , do you have to hold down the power button to shut it off? I always used to think that a power menu would show, THEN you could select shut down, but here, it just shuts down. The power menu flashes sometimes, but shuts down anyway. This may also have me believe that something other than the power button is the problem.

if you hold the power button for 5 seconds or more , it will skip that power menu and reboot. So this still sounds like power button to me.
thanks for the link, been searching everywhere... so fckin hard to search all the S3 threads on XDA. They need to consolidate

Were you able to fix your problem with the fix in that link? I seem to be having the same problem as you.

No, I ended up buying a new phone (I was going to upgrade anyway). I took out the power button, but that wasn't the problem. In a way, it was the button under the button that was sensitive. I would have to take out the motherboard to see the exact problem.

Can't start, can't access recovery or download

Okay. When I put my battery into my phone, the Samsung screen shows up. Then, it restarts, and I don't even make it to the Samsung screen before it restarts again and does the little vibrate it does when it starts. When I try to access recovery, it shows the default recovery screen for a couple of seconds, and then it goes back to what I said earlier. I don't even make it to the download mode screen AT ALL. And when I plug it into the wall, it shows the battery screen for a couple seconds, but then its just back to constant restarts. I have had my current ROM install for a long time now and I just want to flash the stock kernel to my phone. Is there any hope in me being able to get the stock kernel flashed through Odin seeing as that I can't even get to the download screen?

Sounds like a bad power button
Sent from my SGH-T989 using xda app-developers app

Would another sign of a bad power button be that before this happened, my button was SUPER touchy? Like, I would barely lay a finger on it and it would sense it.

I THINK YOU'RE RIGHT. I found a post and some of the signs are: Black screen with intermittent vibrating, unable to enter recovery before phone restarts, unable to enter download mode before restart, phone turns on when battery inserted. Looks like I need to take the phone apart. Thank you for mentioning it could be the power button.

Never mind. The Bandaid Fix for the power button did not work.

There are a few fixes suggested in the bandaid thread. I think one of them involves banging the button with a rubber eraser. Hopefully one will work for you.

I beat the ever living sh*t out of the power button with a screw driver out of anger. Did not help.

Well. It clicks, but the click isn't as... how do I explain this, as quick and CLICK LIKE? It just feels like there is a bit of resistance and it doesn't do a full intense click lol. If that makes any sense.
