[Q]Help, Phone does not turn on

My friend is running CM 7 on his Tmobile G2.
He was describing that yesterday was acting weird with market downloads.
Here is what he he emailed me on what happened.
the phone was acting normal throughout my day until the evening towards the night, i noticed it failed to finish downloading the update for google earth along with google maps. the phone was fine, and then i pulled it out of my pocket a few times and saw multiple times that it was randomly turned off. i would turn it back on and it would still give me the same issue. when i got home and plugged it in to charge, it would boot and then get to the main home screen telling me that google maps is downloading to update. however the update would be frozen, and a few seconds later the phone would freeze altogether, forcing me to turn it off by pulling out the battery. this happened about 4 times, and now has reached the point that it has become a brick and refuses to turn on or show the charging light
any suggestions on what might be wrong with the phone? Thanks in advance. Im running Cm7 on my phone and never experienced this issue.

same happend to me 3days ago, phone running then freezed... bootloop after batterypull... recovery worked for 2 times but had problems with flashing new rom/backing up -> errors with cache partition...
after 4hours of letting it stay off -> it wont turn on again und wont charge (no LED)
tried it with another dz battery+charger... no change... i wrote htc and they answered within 1hr that i have to send it in without battery...
i guess its a known problem (or why wouldnt they want to have me sending in charger+battery .. if its a power-on problem..)
there are semibrick threads here and in other forums.. but they all don't suffer from the power on problem... so i guess i did the right thing sending it in
edit: never had heat issues, never had random reboots, no overclock, no indication of an update from any app did any harm to my phone, running cm7 for 3 weeks without any problems, no hboot flash, no radio flash ... nothing that would indicate a risk of brick (according to guides & forum threads)... first htc that ever failed for me ;(

Thanks for the reply. I will forward it to my friend. I think he is going to try to exchange it at the store and if it all fails we are going to try HTC.

have any of you tried to boot into recovery? did you have eng-hboot on your devices? go to #g2root

its complete dead as in dead... no LED light, no turn on, no hboot mode (or what its called when you press vol+power key).... i dont have a g2 but a unbranded european dz.. hboot and radio was never touched by me

Similar thing happened to me. My phone kept frozing on me running cm7..was fine for a week though.
So I booted into recovery..wiped cache,factory reset flashed another rom got bunch of erros recovery thing rebooted stuck i n htc logo for like 20min yanked out battery rebooted and it never rebooted back. No hboot,no nothing.
My light indicator still worked though but no hboot or anything.. got a new one now have to send the old one back to tmobile but I'm scared that they're gonna charge me for removing void stickers.
Even though I checked twice that removing void sticker won't avoid warranty according to tmobile customer chat sevice..
So I'm thinking about swiping out the sticker that contains serial number and such on back of our phone with the old one and tell them the new one came without a void sticker lolol
Sorry I got way off topic rofl..

We went to the store today and exchanged it for another g2. The guy didnt ask any questions and exchanged it happily for a new one.

This very same thing happened to me today. Updated to CM 7.0.3 from 7.0.1 and the phone was freezing when installing items from the market. Pulled the battery and the phone was stuck on the boot animation. Pulled the battery again, and now it will not start at all. No charging light, no nothing. Had more than 50% charge, and now it seems entirely unresponsive. I can't use the power w/ volume button technique either, because the phone does not respond.
Seems like somehow I have bricked the phone, or the phone just coincidentally died just after updating to CM 7.0.3? (seems unlikely)

just a short update on my case:
i got the mobile back from HTC repairs.
they exchanged my "mainboard" (changed IMEI) under warranty.
i don't know what emmc chip i had before cause it died so fast, but my usb deviceIDs changed completely and are now simmilar to the ones in the cm wiki.
my current emmc is now:
$ cat /sys/devices/platform/msm_sdcc.2/mmc_host/mmc0/mmc0:0001/name
SEM04G

[Q] Desire does simply nothing

Hi @ all,
I have a big problem with my Desire.
I rooted it and installed AOKP Build 39 on it. Everything went fine, no problem up to this time. I did several restarts, everything ok.
Now, today the phone suddenly turned black, no reaction to any command. So I pulled the battery, put it back again, and then, nothing happened.
My desire only shows a black screen, none of the buttons are working (even Vol- + Power or trackball+Power). Even more suspicious is, that the loading LED is not showing up, although my phone is connected to the loading cable.
I really don´t know what to do. Does anybody of you have an idea what the problem could be?
PS: right now ist started vibrating (endlessly...)

I think that you can begin with construction bussiness, cause you have a nice and expensive brick...
Sent from my HTC Desire via flashes and thunders

Trackball + power isn't supposed to do anything, back button + power is.
But anyway if volume button + power doesn't work and that one neither, I think it's a brick as nlooooo said. Also because the LED isn't working. What does it do when connected to PC? Nothing I assume?

Yes, unfortunately connecting it to the PC does nothing.
What do you think, any chance to get it replaced?

if its still under warranty then u could chance sending it back to htc, just say u tried turning it on in the morning and... nothing just black screen. do NOT say anything bout s-off etc etc. im mean if ya cant even access hboot or no led lights or anything how will they know mite aswell try
dont forget take out ur sdcard incase they look at it n find a rom lol

Battery broken?

No battery is not the problem. The same thing with another battery.
I´m still in waranty period, so I´ll have a try
Thanks for your help.
Can anybody imagine why this happend? I mean the rom was working proberly, no errors during flashing, etc. And can a faulty rom/flash cause a fail of even the loading led?
I always thought that such "simple" things as loading are done directly by the hardware without any influence of the software installed on the phone (especially as loading has to work even if the phone is switche offline)

I think it's a big hardware prob. Can u boot into android, even if the screen's dead? Maybe u can provide the devs with a logcat.
Our G7 can be troublesome sometimes......

Maybe it´s a problem of the mainboard. As i cannot even switch on the phone. when I press the power button nothing happens. So, no logfiles.
I´ll send it to the producer tomorrow.

Did you get it fixed?

Issues with booting (blinking orange LED)

Hi there,
I'm having strange issues with DHD. I've read a few threads with issues like this, but symptoms are always slightly different.
Yesterday, I've connected it to the charger (the battery was empty), and when I tried to turn it on, it just did 3 vibrations and orange notif. LED started blinking. When connected to the USB, the Windows recognizes device as Qualcomm, and further reading suggested that the phone is entering service mode, which is normally accessible with Power + Vol+. I've also found out that volume rocker can be the issue, but in my case I don't see anything wrong with it, it's working and looking like before.
No matter what I did, it always did the same, it won't even go into recovery (Power + Vol-), screen always stays blank, the only activity I'm getting are flashing LEDs and vibrations.
Also, phone is charging when turned off (battery removed and reinserted). I've charged it for a few hours yesterday and the green LED was on.
And finally, when turned off, and plugged into the USB, after few seconds, adb devices will show the device, and after the serial number it says recovery. Does that mean that the phone booted into the recovery? The screen is still black though.
So, the most important thing for me is to find out is it possible to return the phone back to stock, in order to send it for a repair. And even better, a solution for the problem

I believe its a hardware problem, although adb says its in recovery. Any more ibfo you could give us? ROM, how you rooted it etc?

thanks don't hurt ya know?

Take off battery,connect phone to charger via USB for 3 minutes ,than insert battery put battery cover now u should see orange light ,now press power button and voila
It's an issue with the volume rocker I think

Had a very similar issue when I had IceColdSandwich on my DHD, only started when I flashed that Rom, reflashed a different Rom, everything is fine again!

I'm not sure that the issue is with ROM, I'm starting to think that it's probably a hardware issue. And that's why I need to found out how to return everything to stock, and send it for warranty.

Try again it will work .may be leave it longer after you put the battery in like an hour .it should work after an hour press the power button

Today, i visit the service, flat cable and battery where reinserted and everything is normal now. You could try this method if you have a warranty. Best regards.

Thankyou so much after leaving phone in cupboard for like 5 years and forgot why it was on there I decided to plug it up. Then I remembered it wouldn't turn on and I was getting the orange blinking. After following your instructions it's all on again. Have upgraded since then so I guess this is a back up phone now lol

Desire broken for good in just a second?

Hello all,
BIG problem here.
A few hours I update the MildWild oxygen rom from 4.6 to 4.6.5. For a few hours everything went totally amazing. But a few minutes ago I turned on wi-fi, but he didn't connect. So I went to MySettings app, but he didn't response. Nothing worked anymore. Only screen of and on, but then I hadn't also the lockscreen. Then the screen turned off, and I couldn't get it on
Pulled the battery out, and put in back in, but my phone didn't restart. Now I plugged in the charger, even the light of charging isn't turning on.
What the hell is the problem with my Desire? He can't be broken in a second if everything worked super well a few seconds before that all?
Tried a different battery but also then he isn't doing a ****... This whole problem came just out of the blue, that's what makes it really awkward to me.
I hope you can help me, I don't want to leave my lovely Desire.
Greets Ramon.

After all sort of things trying, I thought... let's take the sd card out. And luckily he turned on, feels like heaven...
Sd card back in, phone worked also. Don't know what the problem could have been, but my Desire works again.
I hope this maybe could help some other people who had/have/ gonna have this problem!
Close thread please :good:

Hello,
This morning suddenly, the same problem happened... Turned the screen on, swiped to unlock, but during the swipe the phone hang.This time no fear, because I knew what I had to do: take out the SD card.
Too bad, this doesn't work this time. The problem is exactly the same as last time, but know even without the SD card, the phone don't boot, don't charge. Couldn't get into bootloader also. The day before yesterday I flashed Mildwild REDUX V1, but this worked good.
What could it be?
Thanks in advance!
Greets Ramon
Edit: The last time this happened, when the phone finally booted, I directly got a message called something like "android.....com stopped unexpectedly". So that was the reason the phone stopped. Now it would be the same problem I think, but I can't turn the phone on. I just called with HTC, and because I'm out of the warrenty period, I will have to pay the repair (if needed) I think it's not broken, it's probably the same problem as last time...

The phone 'works' again... But it's in a bootloop, and going to recovery results into a bootloop also so I can't access the recovery. So I flashed the recovery again using ADB, but still I get the bootloop! What should I do?

Phone Turning off by itself.

So I have this weird issue with my HTC ONE M7 for a few days now. It would turn off by its own when I was using it but I'd just turn it on and it will work again. I thought it may have something to do with a bad app or the rom might be acting up. Anyway I ignored it since turning it on was a minor inconvenience and I needed my phone functional. Today whilst using GPS, the phone suddenly went dead on me. Every time I boot it up, it passes the initial HTC screen but then doesn't boot into android. The screen goes black and the phone turns off by itself. I went it recovery, wiped dalvik and cache thinking it was an app causing a boot issue but that didn't help. The problem continued. I already had a backup so I went ahead and tried restoring it. It worked the first time. But the phone still won't boot. It would turn off automatically. Then I tried reflashing it with the backup. This time the phone would just turn off as soon as the restore process started. I finally got tired of it and decided to reflash with a new rom. The flash went fine. But lo and behold the same issue again. Boot animation and then black screen with the phone completely turned off.
I thought it might be the battery so I plugged it in to my laptop USB. It booted but when i was setting up android, it would just shut down again. Then I connected it to the wall socket thinking the phone will get more juice. This time around I was able to set it up. With the phone connected to the wall socket all was working splendidly. Please note that during all this time the phone was at 100% and there were no drastic falls in the battery levels.
As soon as I disconnect the phone from power, any power intensive operation shuts it down. I have been in recovery mode for 2 hours now and the battery hasn't even dropped by 3%.
So the question is, What the hell is going on? Is it the battery, is it phone's hardware or is it a software issue? Any help would be greatly appreciated. Cuz if it's something that can't be fixed, I have to start thinking about getting a new phone then. THANKS so much for bearing with me! Cheers!!

if you are s-off i would suggest doing an RUU and starting fresh. Its hard to pin point a problem without having the device handy and trying some things. The RUU will let us know if its a software problem or if its going to be hardware related.

Hey thank you so much for replying. I am s-off. But would going back to stock re S-On my phone? And how do I do RUU? Thanks again.

Do not s-on! Just run the ruu eye dottat made

Installed RUU. The problem is still there. The phone can stay on for hours in recovery without a charger but as soon i want too boot into android it shuts down. It only boots up if it's connected to a charger and that too a wall socket not a usb hub cuz it goes some way into the boot process and shuts down half way. I am pulling my hair out here. Dunno if it's the battery or the mother board.

If ruu still has issues. It is motherboard or battery. From the symptoms, it sounds like battery as the phone needs to have some juice to fully boot the phone before being able to run off the charger.
