[Q] Sensation doesn't turn on after charging

Hey all,
I charged my newly Sensation for a whole 24 hours. At the beginning the red LED was on, and it changed after a while to a green light, as it suppose to be.
I was out for couple of hours, and when I came back- the phone won't turn on.
The screen is (sometimes) turned on, and it like screen-black and not off-black. I tried to pull out the battery, and it didn't helped.
None of my computers recognize the device, and the little LED don't light up if it connected to charger nor to the USB.
Is there anyway I can do reset?
What can I do?
(I really can't get it replaced, I bought it from Negri, and I don't live in the USA.. )
Thanks!

try holding the volume rocker down button while pressing the power button, see if anything happens.

I tried, and it didn't helped.

Try this: take the battery out. While holding volume down and power, put the battery back in. This is something from SGS, but maybe it will work.
Swyped from my HTC Sensation

Nope..
(Can Sensation turn on without it's back case?)
I there anyway I can restore to factory settings using a computer or so?

I think this won't help, it looks like a hardware problem, motherboard failure, I'm not 100% sure though, may be some of the more experienced guys here can help.

That's what I was afraid of.
How can I know if that included with my warranty?

I had this same problem with my first sensation and all i did was take the battery out then hold just the power button and put the battery back in. Like I said "first sensation" it had other problems too.
hope this helps

Well, that didn't work either.
Altho, I must say that knowing that someone else had a situation like that, does help.
Thanks!
Arrrrggg....
Changing the phone now will be a pain in the **..
I'll have to send it back to US, and wish they will replace it for me?

Anyone know what's HTC warranty policy?
HTC gives global warranty to every unit, or it's depends on the reseller?
Thanks..

Whilst I can't help you with the warranty, an email to HTC will tell you exactly what's what.
What I can share with you is that it seems a complete hardware failure has happened on more than just a few isolated examples of the handset.
My first one crashed when pairing bluetooth, I pulled the battery, and from that point, it wouldn't do a thing. No power, no USB recognising on the PC or anything. I went back to my carrier, and they replaced it directly for me.
I can tell you that there are more than just a few of us who have experienced this problem... what causes it - who knows... there is rumour at the moment about a build-up of static causing the touch-screen to fail - if that static goes in the wrong direction... it could easily fry your phone.
My advice - keep it physically 'stock - don't put any covers or anything on, to minimise the build-up of static - JUST IN CASE this is the issue.

Thanks niddnet,
It is good to know it not necessarily my fault.
Is it common that new phones have problems like that? I must say it's really shocking. Phone dies in a middle of BT pairing!? Weird.

[Q] No tablet display but HDMI works.

Hi,
Yesterday (08/02/2013) I updated my tf700t, everything seemed to be fine after it rebooted, I was playing a game, the battery was low, and it turned off abruptly. I assumed it automatically shutdown because of the battery, so I put it in the dock and plugged in the charger. Several hours later I tried turning it on and nothing. I held down the power button for 8 seconds felt the double vibration, but no display. I tried various combinations of docked/undocked, power cord plugged in, holding the power button for 30-60 sec. etc. but nothing.
Out of curiosity I connected the HDMI to my computer monitor and sure enough, it was there, I could unlock it and everything seems to be functioning fine, just no display. The digitizer seems to work fine, although guessing where things are at is pretty tough.
I think I tried the cold boot, volume up/down (I tried both) plus power, and it didn't make a difference.
In order to do the update I had to flush the DMC Client and CMClient data and cache, I had been getting errors from DMC Client crashing.
Also I'm not certain this is update related, as the tablet had been acting wierd, which is why I did the update. I would press the power button to turn the screen on and nothing would happen, so I'd hold it down longer and the tablet would reboot and finally the screen would come on, or it would come on a few seconds after I pressed the button. I was getting a lot of reboots etc... I thought the update might resolve this.
I'm not sure if the problem is hardware, firmware, or software related.
I'm wondering if when I flushed the DMC and CM Client cache, maybe I deleted the drivers for the display or something?
My options seem to be:
1.) Factory reset by feeling around the digitizer while connected to HDMI
2.) Factory reset via the pinhole
3.) Install new (old) firmware via usb/computer. (the device is recognized by Windows 7 so I think this is doable.)
4.) Send it off to Asus. (would this be free?)
So my questions are:
1.) is there something else I should try?
2.) what order should I do the above in?
*Note: I'd like to save my data somehow.
*Edit: I forgot to mention I was on 4.2.1, no root or anything. Also I bought this in July of '12 so I'm pretty sure it is out of warranty. Any idea how much it might cost to send it off? Perhaps I could replace the LCD myself? I replaced the digitizer/screen on an ipod touch, although I'm sure this LCD is much more expensive and much harder to replace. This is turning into a nightmare. So much for trying to keep my data, now I hoping to keep this from becomming a paperweight.
Thanks.

A bloke at work had this issue. He let it rundown and left it for 3 days. It worked fine again after that.

If you don't even see the boot logo, it cannot be software related.

Thanks for the replies.
I'll try letting it run down. Would putting it in the freeser be helpful/safe?
I guess on the software/firmware it depends on the definition. To me drivers are software, firmware is anything written in VHDL. I suppose what I'm really wondering is if it is software/firmware vs. hardware, i.e. is the LCD or some other component dead or is the display just not getting written to, initialized or whatever.

I wouldn't put the tablet into the freezer.
Does the backlight come on? If not, it's definitely a hardware problem. If the bootloader boots fine but doesn't show anything, that also looks like a hardware problem.

I'm not sure about the backlight, I think maybe it does, it is kind of hard to tell. I'll try checking in a dark room tonight. Since the screen is just black I suppose I'm looking for a brighter shade of blackness?
The bootloader is definitely booting fine. That is what I meant in my original post, the HDMI out works, I can see everything there, I can even swipe and tap the digitizer and do stuff, it is just difficult to guess where things are at. Do I need to go back and clarify this in my original post?
Do you think this definitely means it is a hardware problem? I figure I'll try letting the battery run all the way down and let it sit a few days and recharge it as sbdags suggested, in the meantime perhaps I should contact Asus, but I'm not lookinf forward to that.

I don't know what is the cause but like I said I saw this with my very own eyes - the same as yours. Double buzz on boot not screen but HDMI worked. Somehow completely draining the battery fixed it ...... So hardware / software? Who knows? If it was hardware why did draining the battery fix it? The device has been absolutely perfect for 3 months since and has never done it again.....

Thanks sbdags, I will definitely try this. I'm not sure if I should hurry and contact Asus though, I bought this thing around July 22 2012 I think so it is barely more than a year old, not sure if they would cut me some slack on the warranty or not.
Do you think I need to let it sit three days or just make sure the battery is good and run down before charging again? Also I've seen some suggestions for charging from a computer vs. wall as it charges slower, do you think that would be better?
I'm getting into panic mode and want to make sure I don't do anything rash that limits my options.

All he did was leave it for 3 days. Our assumption was that the battery had completely drained in that time....... A charge later (he was actually just about to box it to send to Asus) and it surprisingly started as if nothing had happened.

Having the same problem
I am having almost the same problem, except that the tablet screen works when the wall charger is plugged in. THe HDMI display and the digitizer work fine. It is just the tablet's screen dispaly when the charger is unplugged.

So I didn't have any luck letting it run all the way down.
I contacted customer support, the warranty is only 1 year, but fortunately for this there is an extra 3 months, so I just managed to squeak by, although I'm keeping my fingers crossed.

same problem as you both
i have d same problem well until last week the screen displays when conne ted to wall charger now its all blank but iy works via hdmi, digitizer works fine but all blank, this tf201, does anyone know if i change d whole display it will work?
i already bought the tf701
any suggestions is welcomed and did you get youra to work?

I have not seen people mentioning VHDL and verilog for a while, hahaha... It sounds like you are a low level or physical layer programmer. Any way, a firmware is in general a low level program that communicating with the hardware and the software or high level program ( level 7).. If you will, a firmware is a management levels (level 2 and 3). A VHDL is a level 1 which generates a 0's and 1's or mapping the transistors in the FPGA chip for example.... Oh well, it is just my definition...

If you can get the output from the HDMI port, it is more likely you have a hardware problems. I think that the problems are your display related hardware. If you really want to troubleshoot your issues, you can look on the mother board to locate all the electrolytic caps and check to see any abnormal signs of those capacitors. Those caps are the one that will blew up first before any others parts go....Good luck...:fingers-crossed:

Phone COMPLETLY died while i was using it.

As you can see in thread, phone just dead. Dunno what happened. I bought it an year ago. I've tried to connect it to computer and it was visible as QHSUSB bulk but now i can't see it there. It doesn't react for turning on. I can't get into download mode, recovery mode. Very long time ago i flashed Android MM from xda and it was working good. It had ~50% of battery when died. I've tried to put off battery and then connect to pc but still nothing happen. It has broken screen (was working good) but i've done it in September 2016 so. I can connect it to Linux but i think it won't help too. Any fixes? I think they won't take It at warranty because of screen. Phone looks like dead for ages :<. @edit IT'S NOT DEAD! I've disconnected something from battery this longer one and when i click power i can hear "something" in the phone. And it gets heater so looks like processor is working. But it's still not visible in the device manager.
edit2
i know emmc pinouts.

While I was using the phone, with battery at 66%, the exact same thing happened to mine. I'm sick of it. Time for a new phone.
(Had the rooted V15c image on it, no broken screen, only the camera issue - should someone care)

Same problem here, what is happening . My phone was approximately 80-90% and it suddenly turned off and I can't turn it on ..

bump

Phone went black with warning
The same just happened to mine. It was fully charged and I was using it and then the screen went black. There are no lights when I plug it in, no vibration after pressing and holding the power button. Nothing
I've connected it to my pc and a driver installed, I think the same one as a post above (QHSUSB) but still the phone doesn't respond in any way.
It's the European H955 on official MM 6.0.1 no root or mods and is out of the one year warranty yet was in excellent condition. Does this mean the phone is for scrap and nothing can be done?

Hi, I found a solution to repair the phone in this state. I start by telling you a story, a long time ago I had an HP laptop. video card was detachment from motherboard, and to a stick again we used a method called reflowing. I thought that the phone has the same problem, however we have nothing to lose so I opened the phone I took out the motherboard and started to warm up each chip using a hot air blower. I mounted the phone back and now works like new. I apologize for my bad English I am from Romania.

Any one tried this method and succeeded may please inform on this forum

My phone crashed, would reload to lock screen then restart and finally would not start at all. Before this the rear camera stopped working.
I had reset, flashed a new Rom and replaced the Camera which didn't solve the issue.
After the phone died I tried reflowing though I had no heat gun so I just used the oven. 200c for 7 minutes after disassembly.
That was about 8 hours ago and I am typing on my phone.the Camera is also working.
I will post if it stops again. I did it as the phone was dead and I had nothing to lose.

I have the same problem, and I am interested in getting a heat gun for this purpose. What specific parts of the phone did you reflow/heat? (in terms of the chips, or the entire board.)
Thanks in advance.

What part of the phone did you reheat exactly? The whole phone? or did you take all the plastic out?

Also be sure to take off the rubber part on the back. The purpose is to remelt the solder.l, so only board and nothing else.
To disassemble there are some videos on YouTube. Remove your sim card before taking off the backing
Remember this is a last resort, you could end up with a completely dead chip.

Thanks for the information. Is there a specific way you have to remove the shields, or do I use a soldering iron to get it off? (And if so, does it do any good to solder them back on?)

Did it 395 degrees Fahrenheit (201.66 Celsius) for 7 minutes, I preheated the oven. The camera and everything now works fine.

You shouldn't have to use a soldering iron to take anything off. At least not as far as I am aware of.
I should note that as of this morning my phone when blank and will no longer turn on. I will try reflowing at a higher temperature as some solder may need a higher heat but I am not optimistic that this is a permanent fix.

Hey everyone !
First try to connect it in emergency mode to the computer in order to flash with LG UP. If you cannot boot into emergency mode but the device appers on your computer ( and PC is unable to connext into GF2) maybe you could burn your motherboard.
I burn one 7 months ago with my device resting on my pocket so its a common problem for this device (as official support told me so its full covered by guarantee )
Hope you can solve soon !!!

S7 - Wont start after battery&camera replacement.

Hi, my situation is; got a galaxy s7, the rear camera was bad, bought a new original one, stripped the phone down, fitted the camera, followed the tutorial (ifixit), put a new battery in at the same time, now rebuilt it all, (without the rear case on so can still easily take it apart again) and it wont turn on, wont go into safe mode, recovery mode, soft reset etc, tried every method, also via usb to my laptop, however it does charge, it comes up on the screen with the green battery icon and the LED light illuminates as if it is charging. Therefore, the screen is not damaged. And as far as i can see, all the connections are back joined onto the motherboard, it just wont boot up.
Also, if this makes any difference, I am running the Superman rom.
Any help would be massively appreciated as I have scowered so many websites searching for someone with a similar issue with a solution and I'm struggling, massively!

Are you sure you have connected the battery as required and no other circuit was touched?
Also, do you have the certainty this "new" battery works? I suggest you do the next 2 things:
1. Take this battery out and connect your old one. this way you can check if the new battery is faulty.
2. If doesn't work, even after inserting again the old battery, take your phone to a local repair center. (probably you messed something up).

I'd start by reversing everything you did until it powers on again, if it still doesn't power on with the old camera module & old battery in then start looking at other things, i'd probably start with the battery though as it is a power issue

The new battery charges and it comes up on my screen showing the green battery image charging so it is being recognised. Tried the old battery and its the same situation. I genuinely believe I didnt accidently short anything and im confident everythinf is where it needs to be. Ive just booked in to go to the samsung shop this weekend so hopefully they manage to find skmething althpugh probably end up costing a daft amount. Thanks for the replies so far

New camera module? Did you remove it to see if it is causing the problem?
I know there are different sensors, and if the wrong one is replaced the camera won't work, not heard about it stopping the phone booting but you never know

Just taken it to the local phone repair shop, lets hope they can find something with it. Keep you updated. Thanks so far.

S10e bootloop despite flashing with Odin

To give some context, my S10e (Verizon SM-G970U) decided to boot loop out of nowhere. Since this happened, I have factory reset the phone, no success. I brought it to a local repair shop who said they couldn't fix it. Now I have flashed the phone with Odin and despite the phone being flashed it STILL is boot looping. At this point, I'm assuming something went wrong with the hardware but I don't even know where to start with that. If anyone has any suggestions I would greatly appreciate them.

If it is a hardware issue (which sounds likely), there's an old electronics trick you might try: Power it off, put it in the refridgerator awhile, take it back out and power it on. This has work'd for me with stereo components, for example, as well as a phone. It once revived a hard disk drive long enough for me to capture important data. Oh, but the phone this has brought back for me, an S10e BTW, works only while still cold and has issues with charging while its temperature is low. Still may be worth a try.

Wow, I just did this and to my surprise it worked! Prior to this, I wasn't able to get past the Google sign in page on start up (on good attempts) but now I was able to get it all the way to the homescreen and even install some apps before my battery died. Any idea of what this could mean for the actual hardware? I.e. this means the battery needs to be replaced etc

Great; glad it work'd. Did you attempt to charge it while it was working? Mine actually took charging after warming up only a short time, once. Got it back all the way to 100% charged. But then it quit with dead black screen, and now revives only for a minute or two.
In the old days of individual transistors, we used to turn on a non-working electronic device and blast a shot of freeze spray on various components until the device started working; even with IC (integrated circuit) chips that have lots of transistors. This way, we knew which part needed replacement. But with today's phones, you replace the entire circuit board because the soldering is done by machines; it's too finely detail'd to replace one chip.

I haven't tried charging the phone when it's on. Only when it's off and has returned to room temperature. Seems to me that about an hour in the fridge equals about 5 minutes of screen on time until the phone heats up again.
As for the internal component's you bring up a good point. Even if I were to determine what is causing the issue, I don't have the will/technical know how to buy the parts and do it myself. Outside of just replacing everything, in which I'd just buy a new phone haha.
