[Q] Dead as a rock, fried? - G2 Q&A, Help & Troubleshooting

Problems, again...
Last Thursday, I was at the Soccer cup semifinals (Feyenoord - AZ 3-1 win :good::highfive and I'm not sure cause I was paying attention to the match but I think I felt my phone go hot in my backpocket, idle .
When I took it out of my pocket it was dead, I pushed the power button, saw the LG logo for a split second and after that nothing anymore :crying:
I think it's still charging when I plug it cause my charger always makes a hissing sound.
Is there any other part that could be broken besides of the motherboard?
I could get a used G2 with broken screen for like 30 euros and replacing is a piece of cake so that would be wel worth but maybe it's something else? The rest is only sensors and camera and such right?
Thanks in advance

It sounds a lot like you might have sat on it
It's hard to say what might be wrong with it. Does anything come up in device manager?

No nothing.

If I were you and had the opportunity to get one with a brocken screen for 30 bucks, I'd take the screen of my one and put it into the one which works.
Well no, I wouldn't since the screen is the hardest thing to replace properly. But you can basically transfer all the hardware of the one with the brocken screen into your one with the working screen. This way you can be sure to get a working G2 together.
I assume the variants are the same one so that it is even possible to exchange the mainboards...

Ballad of the G2 ran over by a van...

As you can tell from my title, the face buttons on my g2 isn't working. Let me give you some back ground information about it. It is my sister's g2. She didn't have insurance on it for whatever reason, fell out of her pocket, and got ran over by a 15 passenger van. I took it apart, replaced the screen, and gave it back to her, with everything functional. Couple weeks later she apparently dropped it "just right" cause the screen stopped working again. (fyi, my sister is REALLY bad with electronics...) She decided she's going to get a mt4g so she gave the g2 to me. I replace the screen again, and do the spring mod for the hinge. Everything goes well, boot it up and such. But alas, the face keys don't work. Pulled the battery, did factory reset, neither of these worked. So does anyone have any ideas or clues on what to do?
Wow it got ran over by a van and your g2 is still some what intact? That's crazy... Well I bet you need to replace some components of the soft keys since they might be damaged

When I replaced the screen the first time after it got ran over, the soft keys still worked flawlessly. Was only after my sister dropped it and broke the screen again, that apparently they don't work.
That is insanity that this damn thing got run over by a van and somehow still manages to function. Go HTC your hardware is pretty fantastic despite its flaws.
you can use key tracker to see if the system is registering any kind of key press, and button remapper to reassign the functions you need to the volume up/down and camera buttons or trackpad center until you figure out something better.
Hope this helps.
Thanks ill dawg. The key tracker showed me that its not registering any thing from the home keys, as much as I suspected. I noticed at the bottomish of the screen there is a dead area on the touch screen, so the digitizer must of gotten ruined too, so I have to replace that next. The button remapper does provide an adequate work around for now though.
I think the regular phone speaker got messed up as well, though I'm not sure on that, could of been like that all along, but appears to be damage on the metal "screen" area that protects it, so I'll probably replace that too.
So, while I'm already that far into the phone again (hopefully for the last time), are there any other hardware tweaks I should do for my phone? I have already done the hinge spring mod.
FYI the van that ran over this phone is a 2009 Ford E series van with a large wheel chair lift in the back. The stock weight is almost 5000 pounds, no idea how much the lift adds to it, nor the people inside. So one can only imagine the forces put onto this phone, and the only thing that seemed to have broke was the screen/digitizer and speaker...damn I love htc

I'm not surprised the G2 has taken this amount of damage. The HTC Evo is known to stop bullets and still work flawlessly.
wow...what a tank of a phone.
btw, i'm curious how much do the screen replacements cost? is it really worthwhile to replace it as opposed to getting a new phone?

I bought it off of repairs universe, probably can be found cheaper but meh, was lazy. Screen costs 50, then 5 bucks for T5 Torx screwdriver, then 5 or so for shipping I believe. So your looking at 60 bucks, compared to the 120-160 it was for insurance to replace it(least thats what it cost me when i wrecked my g1). You also need a smallish phillips screwdriver as well, but I had a whole assortment of those already so no idea what it'll run you for that.
The digitizer runs for 65 bucks on repairuniverse, but found an amazon listing for 30 bucks, so figure I'll give that a try.
All said I'll be about 100 bucks into the phone. So cheaper than insurance, and also I feel now that if anything goes wrong with the hardware, I know the innards well enough that I can fix or replace just about anything.

According to source Repairs-Universe the screen and digitizer cost $49.99 and $64.99 respectively.
I suppose to answer your last question it would depend on how handy with a set of wrenches the end user is. I have no idea if "run over by a van" is a legitimate insurance claim, but I know that I would certainly love my phone a lot more if I ripped it apart and put a new screen in. Being able to tell some random bar-jack, "Why yes, my telephone did get run over by a van and all I had to do was replace the screen" is pretty good word of mouth advertising for HTC.

Insurance covers any damage or loss. I could tell them I paid a hooker to pee on me while I played the picolo into my phone and the urine ruined my phone. Approved. Unless you have a picolo exemption on your policy. Then you're ****ed.

well final update. In total I replaced the lcd screen, touch screen, and ear piece speaker, and works 100% now. I did go ahead and do the spring mod and got the bigger capacity batteries from amazon. So yeah other than a few scuffs and such, it is impossible to tell that it was ran over by a 3 tonn vehicle.
It may be overused, but:
It's not a bug. It's a feature.

Grey Screen (NO REACTION) - Please help me out guys

Hey guys...
So, I have my Desire Z since about 4 weeks and nothing went wrong with it.
Really NOTHING bad happened, it didn't fall on the floor, didn't fall into water, etc etc.
So this afternoon I unlocked it and suddenly I got a blank grey screen.(worked perfect in the morning) The phone did react to my power up/on button, but I couldn't see what I was doing. Also the touchscreen worked, because I could unlock it (I heard the unlock noise) but I only get a blank grey screen.
I tried Bootloader and Battery pull. Also I took out my SD/SIM/Battery and just blow through the whole phone but nothing want to happen:-(
By the way, my phone is fully rooted and running on Cyanogenmod7 since 5 days. Everything worked perfect until this afternoon...
EDIT:
Looks just like this http://i51.photobucket.com/albums/f368/forthcomingtangent/DSCI1196.jpg
C'mon guys:-(
So is it grey from bootup till it gets to the rom or can you see your boot splash screen and whatnot?

Yes, when I boot it up it's grey, I notice that it's still working because I get the bootup noise. So I can see nothing. But what I noticed is that the grey screen gets a kinda bluegrey screen while the cyanogenmod7 boot animation(the loop)
Sounds like a hardware issue to me, I'd send it in for warranty if I could. Plus, with your screen being the issue I doubt they would check for something like S-off or anything like that
sounds to me like the ribbon cable for the screen has either broken or not placed in its socket properly, does it make a difference when the keyboard is open? try opening it and closing it a few times... watch the screen. otherwise it could be a fault with the screen board or the screen itself
i would try and claim off warrenty or insurance
No it does no difference when the keybaord is open:-(
Problem at the whole thing is, that I have no warranty because I bought it at amazon.com
you either have to see how much htc will charge to repair it, or take it apart yourself and just check the cables... if any are loose then refit them... or buy a new screen, vga board and ribbon cable and fit it
How much would the last option cost?
And how much do you guys think HTC will chare to repair it?
http://cgi.ebay.co.uk/OEM-SLIDE-FLE...944?pt=LH_DefaultDomain_0&hash=item2a10708cb8
something like that if its the ribbon cable.... but that gives you the whole kit
http://cgi.ebay.co.uk/Touch-Screen-...K_Replacement_Parts_Tools&hash=item2a0fd454a5
thats the digitizer but i dont think youll need that but just in case
http://cgi.ebay.co.uk/NEW-GENUINE-H...K_Replacement_Parts_Tools&hash=item2eb3f529d0
thats the screen
but in fairness your better off taking it to a repair shop and getting a price... if you havnt got a warrenty then you dont have to worry about loosing one
Wow thanks, you're really helping me.
So I found a warranty document, since I bought it over amazon.com from another seller(mobilejoker) and it says that they'll repair me my device if it is defect and not my fault. But they also charge 40$ if it's an obvious damage made by myself. Well, I don't know, it wasn't my fault right? I mean it's not like it dropped in water or fell on the floor.
looks to me like its the ribbon cable or the vga board for the screen, as long as you havnt dropped it in liquid, on the ground or opened it up then it cant be your fault... id go with the warrenty first before you open it up
Hit the thanks button please matey
Done
And thanks again for your help.
alrite glad i could help, if you get stuck or if the warrenty doesnt work come back
hey guys I'm having a very similar issue on my phone, I bought a screen on ebay from a USA seller, as well as a flex cable cus both were damaged in my phone. I've got both of those installed and the phone boots up, gives off noises and vibrates like his did, but no video. Backlight lights up, but just black. I've been googling a lot and apparently the grey screen is just a precursor to what I have. Where exactly is the VGA board? is it on the main logic board? does it need a reflow like some laptop chipsets?
Hey guys I just thought I give you a quick update.
So I got my device back, it's working perfect and I didn't have to pay anything for it.
I'm just a bit confused, because my phone now is totally unrooted, and I always thought that root hurts your warranty.
Anyways, thanks for your help!!

Either they gave you a new phone or...
They replaced the screen (or samaged parts) and wiped or perhaps upgraded to newest stock.
Do you still have all your info and apps that were previously on it?
What version of android does it show in about, and which hboot do you have now?

Does the computer recognize it?

If you're talking about no power at all, it doesn't sound like a software issue. It sounds like an electrical issue.
If the screen backlight comes on when you hit the power button, then it could be software or electronic (borked chip, broken circuit board, etc)
Plugging it in, even if it's a dead phone, should still charge the battery if the electrical circuits are good. The LED will come on at orange or green and that should tell you if there is physically electricity running through the circuits.
If you get nothing, something in the phone died. I'm starting to realize the MT4G has a pretty poor build quality.
If the battery is charging and the backlight comes out, maybe a quick vibrate to indicate charging, then you could have some kind of an electrical short in the circuitry somewhere.
Or you just have a bad power button. That's a possibly. But that's odd that it turned itself off. That's what makes me think the power button itself isn't what's wrong.
In all cases it sounds dead. If you can't get to the recovery screen there's not much you can do.

no led lights it just died lol... it wont do a thing. im starting to think that it has some kind of short between the battery and the circuit that distributes power through out the phone.. thats my best guess.thanks
You can also check to make sure the battery isn't the problem by removing it and plugging the phone in. Again, the best you'll get is a brief flash of the backlight. But if you don't get that, you can be sure the battery itself isn't the problem.
Or just put a new battery in and see if that works.
This is highly unlikely to be the cause. But it's all about narrowing the possibilities. I've been fiddling with electronics for 20 years now. One thing I'm sure of is that you should never discount the really unlikely source of a problem. It won't usually be the answer, but every once in a while something you'd just never suspect ends up being the culprit.
I had the exact same issue, earlier this year. Your emmc chip gave you the bird. Go into Tmobile store, tell then your phone won't turn on, you tried the normal tricks, but nothing works. Act a little dumb with them,I did that an got a new one under warranty for $5, came in the mail the days later. DO NOT MENTION ANYTHING BOUT YOUR PHONE BEING ROOTED. If you do, your gonna have to pay full price for a new one or though the issuance company a $130(or whatever your deductible is).
Trust me on this, it works. I'm still using the phone they sent to me back in June.
If I helped, give thanks(via the button )

Took it apart, put it back together. Somehow it works better just from doing that?

So, took apart my xplay today because my screen was having issues and I wanted to see if a cable was loose.
Couldn't tell what was wrong, so I put it back together.
After putting it back together, I noticed a few things.
1. The power button that had always been loose was suddenly tight and in one spot. I thought the phone was just made that way. Turns out mine was improperly assembled right from the time I opened it. Gotta say, that button is far less annoying now. Anyone else have a loose power button?
2. My battery. Before taking it apart, my battery was at 19%. After putting it back together, suddenly my battery said 43%!! Suddenly it's got more? The heck is going on here?
3. My screen hasn't glitched again so far. Even though I didn't actually do anything other than unplugging/screwing and replugging/screwing some parts.
4. Originally, the left trigger felt "mushy" now it clicks like the right one.
On a side note, after seeing how the slider works on the inside, I recommend ONLY opening the slider when you're actually about to play a game, and not just fiddling around with the phone. The way it's designed makes it very obvious to me that the ribbon connecting the screen to everything else is easily destroyed. It wouldn't surprise me if my screen was having problems because of that ribbon.
Edit: NOPE. It's totally screwed.
Edit again: When the screen is glitching, moving the slider makes it start working some of the time. I'm becoming more and more convinced the ribbon cable inside the slider is the problem.

Strip of unresponsive screen when powered on for a while?

So something I noticed on my old note 4 is that the screen has a strip unresponsive to touch (pen works fine).
The thing that weirds me out is that when you reboot the phone, it works perfectly fine, but after being on for a few hours, the middle part of the screen just stops responding.
Rebooting revives the part of the screen, but not for long. Factory resetting it does nothing different and it's running completely stock firmware and software.
Any ideas as to what's causing this? I'm not sure if replacing the screen would help since it seems to work fine for the short duration that it does.
It sounds like a digitizer problem. I wonder also if the heat of the phone is causing something to change or even physically warp to cause the unresponsive part.

Either a blown display or mobo.
A trace, solder joint, micro weld or junction failed.
It's possible it could be a connector/ribbon cable failure in which case easily repairable.
Check the display/mobo ribbon connectors...

I'm pretty sure it's not heat since you can turn it on, leave it on a table, idle without anything running, and it'll be completely room temp and the part of the screen stops responding.

Could be literally 100s of thousands of parts that could have failed; semiconductor junctions, resistors or caps.
Solder failures aren't uncommon either.
If you spare parts, use the process of elimination. If you really like that model having a few parts queens around is a plan.
Hopefully it's a connector contact... check all connections including grounds.
For $650 you can get a Note 10+ 512gb in excellent condition... don't got too nuts trying to fix it.

Sorry to hear that.
Some devices seem to defy being repaired.
45 years ago Tom Schall owned a TV repair shop. He was an excellent technician with a engineering degree in electronics.
He swapped out a trouble filled Magnavox chassis with a known good one for a customer after repairing the original one at least twice only to have another circuit fail.
After a month he did the swamp but continued to try and fix the original. He repaired completely different sections of it only to have another one fail, HV, tuner, horizontal output, audio, and more.
Never once did it survive a couple days of burn in, sometimes only hours. It got to be a running joke. Hundreds of test point checks, scoped it, testing isolated components pondering how it could be so cryptic to repair. At this point no one else would even touch it... but Tom persisted for at least 3 more years in his spare time.
If there's a heaven or hell I'm sure Tom's still tinkering with that chassis. RIP
They weren't called Magotboxes for nothing

Any ideas as to what's causing this? I'm not sure if replacing the screen would help since it seems to work fine for the short duration that it does.

See if this works for you, it did for me after i thinking digitser was kerputt.
on Dialler, dial: *#2663#
if a menu comes up, choose the top left option to upgrade the fw for touchscreen, wait for complete, then hit home button and see if it works. Maybe best to try after your screen goes funny, it should fix straight away

That worked at first, but I rebooted the phone and it seems to be doing it again. I tried to update the firmware again, and it's not working. Any advice? It worked fine for over a day without any issue after doing that at first, now it's back to doing it again.

Sorry late reply, I didnt get a notification. It worked for me and I haven't had to do it again, it likely sounds like you have a hardware issue unfortunately.
Only other option maybe, is putting on a custom rom, which will instigate a full system wipe and a new fresh software install to a more modern Android version. Possibly may be worth a shot?

Alright, update.
i tried again, and it fixed it, but a while later, it did it again. Since that seemed to fix it for a bit, i can't imagine it being solely a hardware problem.

honestly, that's the plan as of right now. As much as I like the S-pen features on this, it'd be for the better if it fixes it.
Update, TWRP + new rom installed. Still does it.
With Refined Nougat N7FE, I'm able to open the screen firmware menu from the dialer and update like with the stock rom. It sometimes fixes it for a while, but ends up doing it again.
