Stock G2 won't turn on

I have a stock Tmobile G2 that I have not rooted or done a thing too. I've been enjoying it just like it is.
Last night, I plugged it in at night and went to bed. This morning, the green LED was on saying it was fully charged, but it wouldn't power on? I finally pulled the battery and it powered on to the standard white HTC screen, but hung there for 5+ mins. I pulled the battery and again and I think the HTC screen came up again and hung again. After that battery pull, I could no longer get it to even power on.
Here's what I've noticed.
-After a battery pull and then plugging it in, I get an "orange" LED, but nothing happens. Can't power on, and it doesn't ever seem to turn green even after hours on the charger. When I remove the plug, the orange LED stays on and nothing happens.
- If I pull the battery and try to turn it on before plugging it , nothing happens, but in the same token, it won't show the orange LED if I plug it in.
The only thing different I did last night was that I used a Mini to Micro converter plug for the first time. I have a ton of Mini-USB plugs, so just ordered 2 of these. Could have been coincidence, but thought I would mention it.
My battery has been fine and has shown no issues of being bad, but wondering if they just crap out or something? The no charging LED after trying to turn it on is strange?
Any ideas?

Return it and call shenanigans?
That's really quite strange. Have you modded anything on the system that would affect it at all?

yeah, the hardware in your phone is simply broken. to make sure this is true, try doing a recovery. pull the battery, put it back in, hold the volume DOWN key, while hitting the power on button, use the volume rocker to go down to recovery, and then follow the instructions to recover the phone. but it sounds to me like water damage of some sort around the plug, or you pulled out the charger wrong and broke it. **this will remove all apps you have installed, but its better than having to wait for t-mo to send you a new one**

Haven't touched a thing on this phone. I have an older G1 I've played with ROM's on and stuff, but I've left the G2 alone.
Only thing is standard apps from the market.

Just tried the recovery, but nothing.
No water damage or anything. Phone has been well taken care of and looks new.
I guess its just a failure. Only had it a month or so. Guess I'll contact tmobile about a replacement.

These things happen, my original G1 died after about a week of use, though I would have expected that after a month you would be in the clear.

Yeah, kind of surprised myself. Electronics do fail though.

I'm on my 4th G2. The screen kept going out on two of them and the other one, all the apps were force closing on me. I almost gave up on this phone and went to a nexus s but I love the quality of this phone as in it don't feel or look cheap. Also I would have missed my hardware keyboard for my fat fingers lol. I was not going to get a mytouch 4g. Wanted to get as stock vanilla android as I could.
Just send it back and get a new one. Hopefully the next one won't give you these problems.

[Q] Bricked phone or battery?

Hi,
So my girlfriend just got given a used HTC Desire by a friend last monday. It was locked to Orange. Like all android based devices in this house, the first thing I did was unlock all the various bits, flash a decent rom, update the radio etc. and all was working fine all week including the battery dying totally at least once.
On friday, she had to do a 22 mile charity bike cycle for work (chump) and after she got home, she spoke on the phone for a while. Then the battery died. Now it's foobarred.
When I put it on charge, light doesn't come on straight away (hinting usb-brick)
Eventually the light comes on and goes orange.
It then goes green
When I press the power button, the green light goes off and NOTHING happens.
I can't get it to connect to the PC at all.
But since I can't boot it, I can't get into recovery, I can't get the PC to see it so can't use ADB.
I've tried all sorts of combinations of removing the battery, leaving it charging for hours, leaving it with the battery, sim and microSD removed for hours and can't seem to get any life out of it.
The phone looks fine, the water indicators are all still white. My only ideas aside from some catastrophic failure on one of the boards is maybe it's the battery that's shorted itself or something. Does the Desire turn on at all when plugged in with a fudged battery?
Anyone else had a similar problem? Any ideas on how to fix it? Phone or battery?
I'm trying to hunt down someone with a HTC Desire at work so I can test their battery with it - is there any chance this phone could make an expensive paperweight from another battery too?
Thanks in advanced.

Hi.
Maybe the battery, in his last breath, overcharged some circuits and burnt them. But I hope not for you. If the red light/green light works, it means at least that some of the circuit is working so continue your chase and find yourself another battery for testing.

Try and test the battery with a multimeter just to be sure ! Also what about charger was it original htc one ?

Did you ever sort it out?

Did you got this solved? I've got myself a new phone (giveaway ) and gave my Desire to my wife. I could flash another hboot and back to cm7 without any issues, she configured her google acc etc and put it onto charger over night. But it didnt charged. On yesterday morning it then died cuz of empty battery and dont come back now...

[Q] HOX w/ possibly semi-dead battery

We had a power surge in this house while my HOX was charging... I'm guessing that's what caused the problem.
Unfortunately I bought it outright, 2nd hand, about 7 months ago. So can't get it replaced or repaired for free. It's been trouble-free until about a week ago.
Phone is rooted, has been upgraded/running Jellybean ROMs successfully; originally an Optus branded HTC One X (Australia).
The Problem:- so by default, if I charge it (with solid red LED on) while it's off, at random intervals with no user intervention, it'll boot to the boot screen, and then turn itself off to a black screen a few moments later. This will continue at random intervals of say... 30 minutes or so. Strange huh. Oh yeah, and when I try to boot the phone manually, it does the same thing. Annoying.
I can still get into HBOOT/Fastboot using power+voldown... and from there recovery. So I thought - okay... I can fix this. But upon booting, no matter how long I charge it while it's off, it complains that the battery is too low to flash. So I've been charging it in recovery for hours before flashing successfully.
So I've flashed a couple of different JB ROMs (such as Ordroid/Black Pearl) with their associated boot.img files properly (the way I always had before, i.e. before flashing the ROMs, and w/ fastboot erase cache etc), and each time it'll boot up into the newly flashed ROM fine, then I'll charge it up to full (green LED). But upon rebooting the phone, it goes back to it's initial behavior of going to the boot screen, then a few moments later going to the black screen and staying there (with red LED on). And then when I boot it with power+voldown... it complains the battery is too low to flash, even though fully booted and working it was saying it was 100% charged just a few moments before (having previously left it for hours to charge up to full). I've tried 2 genuine HOX chargers and cables, with no change in behaviour, and have searched threads about this kind of thing in this forum, to no avail.
I suspect the power surge has killed the battery somewhat , though I really don't know for sure.
Or is this a PEBCAK problem... could easily be... I'm sure I could've stuffed up somehow without realising.
Fixing this phone isn't critical, as I'd already moved on to a Nexus 4, however I had been intending to give this phone to my brother before it started misbehaving... so if anyone knows how I should proceed, I'd most appreciate any guidance.
Thanks.

It's a bit difficult to say whether it's the battery or the actual mainboard which got damaged.
There's only one way to find out, purchase a new battery and see. You can sell the battery if it doesn't work.

Blinking LED, doesn't charge, can't get into fastboot

Hello!
First of all - yes, I am completely aware that there are MANY similar threads, I've spent almost 3 hours now finding solution, no luck. I hope some good soul out there will be able to shed some light on my case So here it is:
Today, I was caught in a bad moment with low battery, and the phone discharged completely and turned off. I've connected it to the charger just about 5 mins later max, but the blinking LED of death got me there I have it on a charger for about 4-5 hours now (original HTC charger, of course tried both, the wall and the usb), the LED is still blinking, phone is cold (it's getting quite hot when it's charging normally), no reaction whatsoever, can't even enter any fastboot or recovery or anything. I've tried every possible combinations I have found, vol+ & power, vol- & power, both volumes & power, long, short, nothing helps. Now what's different than any other threads out there? The phone was NEVER rooted, I didn't unlock bootloader, flash, nothing. It was as stock as it could be since I had motherboard replaced (2 years ago, on warranty in HTC service). Now the warranty has ended, so I'm really hesitating to send it there, as it's propably gonna end up with new motherboard again, no matter what the problem really is (I live in Poland, and that's just a common "fix" no matter what the problem is). Current motherboard is the one with CID B25 (the one that never got any update, so it's stuck on Kitkat for 2 years now). Everything was working completely fine just a few hours ago, nothing indicated any battery problems, it just discharged, and now I can't get it to work.
Does anyone have any helpful ideas?
Thanks in advance
@edit
Forgot to add it's a single sim version, model OPFJ400 D820n

Hello Scar9,
I had the same problem. To fix it, I had to charge my phone for 30 minutes. After that, I remove the back cover (to access to the battery). I connected the phone to my PC and I disconnected the battery. I wait any seconds (maybe 10 seconds) and I reconnected my battery (still the phone connected). The screen display a law charge of my battery (around 5 percents) but I can start my phone. After that I fully charged it and all seems OK !
I hope that can help you.
Regards.

Have you got any solution for this problem.
I too have same problem..

Hi everyone,
I'm trying to revive an HTC Desire 820 (dual-SIM model) that I have. There were several hardware issues with the phone - main one being the battery _completely_ blown and bulged out! So, I replaced the battery, along with the complete battery charging board, and the complete LCD display (which was also gone!)
Now, the issue I'm facing is, even after replacing 3 of the major parts with new ones, the handset is just not coming back to life! The red/orange LED on the front just keeps blinking (indicating that the mainboard is still working) but the phone simply does not respond to any combination of buttons, or even when I connect it to my laptop!
My core question is: Do I really need to have the _original_ HTC charger and USB charging cable (both of which I don't have) to get this thing up again?
If I can get some help and some clues as to what exactly is wrong here, I'll be really, really, REALLY thankful to you...!!!
Thanks a ton in advance!

Phone dead for no reason after years?

This entire forum is probably dead, but I'd like to ask anyway.
I've got the same problem as other people in this forum.
It has an unlocked bootloader, LineageOS 18.1 unofficial beta and it's rooted.
When plugging the Z5P in the charger, it doesn't turn on. I've removed the backplate and unplugged the battery and plugged the charger,
the phone LED blinks red with the off time of ~3-5 seconds. Previously the screen logo flashed for a very short time but now it doesn't even do that.
Now when I plug the charger in and then connect the battery the moment when the LED is red, the vibration motor reacts 3 times and the phone stays off.
Connecting to a PC and doing any steps above, the phone does not get detected by the PC, so obviously there's no way to use any recovery tools.
Is the Z5P finally dead/chip fried? Can I do something with a dead phone or the internal parts?

If the motherboard is not totally dead then you could try the option with QPST tool to flash the stock ROM in download mode (QHUSB-9008) just search for, you should have a long curve learning to do so.
The device has to be detected this way, but it may work or not, depending on if the chip is really dead or not.

Yeahhh, phone still doesn't get detected on PC, not really turning on. It's probably junk now.

To send it to download mode (EDL) you have to open the back cover and test point two specific pins from the motherboard.

I just wanted to say that I got the EXACT same issue. I installed LineageOS 18.1 about 4-6 weeks ago and when I wanted to play around with the phone again a few days ago it wouldn't turn on or charge as Vanta-Chan mentioned.
It would be interesting to know if this simply happened because the phone is old, and to be honest the battery was already very bad at this point OR if this is because of installing LineageOS.
Because to be honest, that made me really scared of installing Lineage on other devices... I was thinking about doing it on my main phone (Samsung Galaxy S10) in the near future, but this has left me really scared.

Reading the issues y'all are experiencing reminds me of my old Xperia Z3, didn't want to turn on at all. Vibrated a few times with no display... No charging, led blinking with charger connected but PC won't detect...
The fix for my part was changing the battery, which did make it work. So most likely the same case and it's the battery, and trust me. Those knock off batteries are trash, didn't show correct battery %, and died after a few days... So had to get a new "original" one, no issues with the battery till this day

Old devices turn to act erratically, unpredictable behavior can appear.
Just one thing I can sure you, I flashed LineageOS (although is not my preferable one) in an uncountable number of devices, never had an issue like that. If you follow all the steps indicated by the developer, you wouldn't have any troubles at all being on this device or another one.

Thanks for the replies... I might change the battery then, if it doesn't cost that much to let someone do it for me.

UPDATE:
I had some time today and somehow decided to play around with my Z5 Premium.
Now... I might should open another thread if necessary, should this get too much out of hand based on the threads topic, since my issue may be more different than I thought.
Previously I couldn't get it to turn on anymore after the battery died, charging as well wouldn't work and I would get that LED blinks for a short period of time when I would try to charge it.
So for whatever reason I decided to charge my phone again and at the same time pressing the power button + volume down... I tried that previously, but today it worked!
What happened was: I got the charging screen + red LED light over and over again and once I stopped holding the buttons it would start to boot again into a similar screen I got when installing LineageOS 18.1, with the only difference being that I had the battery symbol showing up as well as only seeing half of the screen (left side) since the right side was buggy only showing vertical black and white lines (which I had happened previously installing LineageOS after booting into TWRP)
My phone is now fully charged and I was able to turn it on and everything looks fine so far, except for the colors especially red which looks really dark since installing LineageOS 18.1
Now, this seriously has me worried about installing Lineage on my main Samsung phone. Because right now I feel like this has something to do with me installing a new OS on my phone...
Kind regards

I ain't no expert but there is a tool that you can buy and you plug it in your phone that will send you str8 to recovery mode or download mode, Idk if you are willing to pay like 10$ I think its not that mush to get it its a useful tool

Probably you are referring to the EDL cable (it costs around 4 USD), I have it, and it worked with a defective device with a volume button not working properly. I have to add that on devices with locked bootloader it can be more useful that with devices with unlocked bootloader that have many more possibilities to send it to any mode you want without the need to open the back cover.

If the ROM in this case, LOS was built specifically for your device model, and it comes from a trusted source shouldn't damage your device in any way. How custom ROMs work with all the variants should make a difference on how they look, just, apparently. Anyway, check that your battery is not draining, or it is damaged in some way.

I got the ROM from the thread right here: https://forum.xda-developers.com/t/rom-beta-lineageos-18-1-for-the-xperia-z5-premium.4202705/
The battery isn't the best anymore, but I feel like it improved a little bit since installing Lineage.
The phone was charged to 100% on Saturday and currently, it's at 50%. And nothing looks damaged
