[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.

N5 in bootloop - possible hardware fault related to power circuit

Hi guys
Unfortunatly my time has come to have a possible hardware issue.
Yesterday my N5 was connected via USB (like I usually leave it resting at work / charging) and out of the blue, rebooted. Google logo shows up, and reboots right away. Trying VolDown + Power shows up the menu but I hardly have any time to select bootloader or recovery, and when I do, it eventually reboots again after a couple seconds.
I'm able to turn it on and have it on if I avoid touching the power button, when I do, sometimes it works (screens just turns off), sometimes ir shuts down after a few seconds after doing so. It's not always, but happens three out of five times.
Connecting the USB cable has the same behaviour, sometimes it's alright and I'm able to copy files and so on, sometimes it shuts off and there it goes into bootloop again.
So, I got home, opened it and I looked like a donkey looking at a castle lol. I had a disconnected brown wire on the right side of the battery which I was able to fix, but that doesn't seem to be the cause of the problem.
The power button feels ok, it's not exactly rattled or anything, it has on/off feeling. if you know what I mean.
Problem is, I bought this in second hand in london about 6 months ago, would be hard to RMA and probably they would give me the finger.
Anyway, suggestions? Anyone went through anything like this? I doubt it's a software issue (rom) cause the same behaviour happens when on recovery / bootloader. Sometimes it holds on and lets me do things, sometimes it doesn't. Most often, doesn't.
Any help or tips are greatly appreciated.
Thanks guys.

I can't, was bought in second hand in a shop, besides I opened it and the water sensor is pinkish (never touched water, probably humidity).
I can only do that around christmas time.
Any other tip ? Something I can do before considering something like that?

By sending in for repair or replacement, I meant to LG. Not Google for RMA.
LG will charge you for the repair or replacement.
There really isn't much you can do otherwise.

Nexus 5 Screen issues - Erratic

Hello!
I have a Nexus 5 with no warranty (according to LG, I need a receipt which I don't have) and the display is acting up. I noticed if I slightly bend the phone, the display flickers, sometimes fixes the problem, or it turns off. Over the last 6 months, the touch screen has been erratic and sometimes I have to hard reboot the phone to get it working again. Also on startup, sometimes I get the rainbow coloured "static noise" on the screen and then I push on the screen a bit and it is working again. Does anyone have any ideas what might be the cause and how to fix it? I feel like it's a ribbon cable problem but I have no clue. I went into Bootloader and factory reset it multiple times, pushed the factory image, pushed TWRP and Cataclysm.
Thanks for any and all help!

Replace the flex cable. It's fairly cheap.
If that doesn't solve your problem, then it's a screen or motherboard issue (i'd recommend paying LG for a repair rather than guessing between the two and possibly wasting money).

Thanks for the info. I have been looking for a while but I'm not sure which flex cable to replace? From the iFixIt teardown, it doesn't look like getting to the display cable is easy/possible. Do you have any links for what I should purchase? I'm comfortable with taking it apart and doing the work, just want to make sure I buy the right piece .
Thanks!

power button issue/no cell reception

Hey guys. Here for some dire help. I need to send in my nexus 5x for warranty replacement but don't have the $349 for google to put on hold so while I wait its back to my nexus5 mess.
I have two 5's. One has the power button, constant pressed state issue. The other one got wet and only the cell reception doesn't work. Everything else does.
The one that got wet actually registers my T-Mobile Sim on boot and it seems as if it should pick up signal but after that brief moment it goes to no bars and emergency only.
Was wondering if there is a part I can swap from the power button unit to the water damage unit to make one working 5 until I can get my 5x working again. Any thoughts guys?

Have you tried putting the "wet" motherboard in the other Nexus 5?
I recommend replacing the power button on the unit where it is constantly pressed is swapping motherboards does not resolve the issue.

Tried swapping mobos and get the same issue of no cell reception no matter which phone the wet board is in. If I had soldering equipment id just take the button from the wet and put to the other one.

When I press the power button to lock the phone, It turns automatically on the screen again openning the camera, someone have had the same issue?

Yeah bud. What's happening is the switch thinking it's long pressed so you get the camera coming up. Soon it will be going into boot loops and stuff. You can get a button cheap on eBay. Just have to solder it on. I need soldering equipment or id have switched mine already.

Pixel 3a always on and bootlooping, any suggestions?

Hello.
For maybe the 5th time I just took apart my old 3a that my son's been using. I was going to replace the battery, but turned out the battery I'd ordered (OEM and fresh from the wrapper) was bad (puffing up). Needless to say, I didn't replace the battery just now. The old one was managing ok, so definitely wasn't dead. I removed it carefully, so figured I could just reinstall it until I got a better one.
Having put the phone all back together (unfortunately, breaking the cable for the fingerprint sensor along the way, but AFAIK, that would have nothing to do with my problem), I found the phone was bootlooping. Not just that, but once I took it back apart, I found that as soon as I plugged in the battery to the motherboard, it started to boot. Holding any combination of buttons didn't stop the bootlooping. I'm just seeing the start screen (it's rooted) and maybe a flash of the Google logo, then back again. I can't turn it off without unplugging the battery.
So now I don't know what to do with the thing. I thought I'd just put it back together and let it limp along for a while, but suddenly it's hosed. Has anyone else experienced this kind of behavior and found any fix?
Thanks

Never took my Pixel 3a apart, but first thing I'd check would be power button - it might be stuck (always pressed), might be "shorted".

I didn't want to complicate the story, but I did also replace the entire power switch. No matter, it does the same thing with the old power switch, the new power switch, everything connected to the motherboard, or nothing connected at all except the battery. Also, whether or not it's plugged in. IIRC, the battery had over 60% charge when I started this morning, and it's been keeping the phone going for a whole day. I feel like something must be up with the motherboard itself, but don't really know.

Could the touch sensor being broken actually cause this problem? That's the only thing that's different. I don't even know how that cable got broken, as I tried to carefully remove it from the motherboard. But it's done, and to test that theory, I'd have to buy another.

how is power switch connected to the motherboard? Is that connection 100% intact nor damaged? By the way, if fingerprint cable is broken, maybe that connector is damaged too and is causing short circuit?
And can you enter fastboot or recovery mode?

Sorry, this might have gotten buried in my last reply:

I don't have the broken fingerprint sensor cable attached at all. Tried it once, but figured that was pointless if not counter-productive.
I've also cleaned all the accessory contacts, including the one for the power switch, using 91% isopropyl. The only thing I haven't done, and the last thing I can think to try, is to really hit the motherboard with compressed air, especially the contact for the power/volume switches. I just know it worked fine after taking it apart multiple times, before this last time.
If it's not some damage to or debris in the power-switch connector, at this point I'm thinking the motherboard's gone bad in some other way.

Asked over in iFixIt, and was informed that it may well be that not having the fingerprint sensor attached could cause POST to fail, so I'm going to try a new one and see if that helps.

New fingerprint sensor, per this recommendation. Phone still endlessly bootloops. Seems to be permanently powered on, cannot stay in bootloader/fastboot mode for more than about 2 seconds. The buttons all register -- e.g., if I hold down all 3, the phone goes black, but only until I release them. There seems to be no way to intervene in the problem. I think I may have to give up on this, unless anyone has further suggestions (beyond a new motherboard, since I've already invested too much time and money in it).
