[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!

[Q] Need help plz phone died

Hi there
I updated my phone to jellybean yesterday i am with tmobile uk , the phone worked fine after this everything seemed to install ok.
until a hour ago, i got a phone call answered it, then hung up, i put my phone in my pocket, next time i took it out the phone was locked on the boot page the white screen with htc logo on, i tried to power it off and the the 3 buttons on the bottom of phone started to flash white for 10 seconds then phone swithed off. the phone wont turn back on, it wont charge, tried usb to computer no lights nothing. the phone was fully charged when it switched off. my phones a standard one never touched bootloader etc
i spoke to htc they think its software problem, they say when i downloaded jellybean i used 3g not wifi (my fault) this could have caused the problem as there could of been a drop in signal they tell me.
the problem i have they want 210 pound to fix and they say its not under warranty as i have had the screen replaced, but not by htc voiding the warranty.
Can anyone here give me some advice or help to fix my phone please.
thanks

Can you enter the bootloader by holding the power button and the volume - button together, keep them pressed until it enters the bootloader.

[Q] HTC ONE V fails to start, please help.

My brother is using HTC ONE V for last 8 months. He got it rooted from his friend some 20 days back, was on stock rom. Yesterday suddenly phone got switched off in the afternoon. he tried to restart it, tried to soft reset- by holding power button. and tried to hard reset by holding power and volume down. but unfortunately phone didnt respond, he connected to a wall charger but no led notification light. now today evening, when he got back home, i also tried same things, but no luck. At last I attached it to my laptop via usb cable, and led notification light was back. I allowed it to charge it for some time and then tried to start it with power button. it worked. phone worked for about 20 mins, during that time it auto rebooted one time, but we thought problem was solved. we also did factory reset to make a new start, it worked fine..phone worked like new for an hour, battery was around 50% or so, and then.. went dead again..we just inserted micro sd card and sim..few minutes after that it went DEAD.. now even laptop isnt recognizing it. no led notification light or windows sound when connected to laptop.
Can anyone help? what has happened? Is it some battery problem??
thanks and regards,
K

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.

[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.
