Problems Turning On

I've been trying to reboot the phone to try to get into CWM so I can make a backup. But whenever I turn off the phone and then try to turn it on again it won't turn on. It eventually turns back on but after I pull the battery out and back again a few times.
Anyone else having a problem like this? And I'm sure the battery has had a charge before I powered off. Also is there anyway I can do a reboot or CWM with an app or something?

You know you have to hold the power button for a few seconds to turn it on, right? Not doubting you, just figured I'd put that out there just in case the solution to your problem could be that simple.

Haha yes, I've held it for much longer than a few seconds to no avail. I just keep removing and putting back in the battery and it eventually turns on. Could it be that I just have a bad battery?

Sounds much more like a bad power button to me. Do you have issues turning the screen on and off when your G2x is powered on?

[Q] Restart Problem

Hello,
I just got new sensation and when I use the power button and the restart option the phone seems to turn off and not reboot. A press of the power button is needed to start the phone.
Anyone else know of this, am I being dumb or is this a problem?

I got my Sensation yesterday and had a similar issue. My power button got progressively worse as the day went on. It seamed as if the power button was being held by itself and would bring up the power off and the reboot options any time I touched it. Then as the day went on the power button stopped working all together and I can not unlock my screen. Unless I get a call or pull the battery. Pretty disappointed in this as I never even got to take the phone out of the house before it **** the bed on me and now I have to wait till Monday to get a replacement.

how long are you waiting before manually doing it? it is a computer, it needs to shut everything off & then restart. give it a little time. if it take 2-3 minutes, then something is wrong.

if you uncheck the "fastboot" option it will not restart when you hit restart. If you keep the "fastboot" option checked it will restart

not true. just tested to be sure before replying, but my restart works with fast boot off

Uncheck fastboot then power off the device. Power the device back up verify fastboot is still unchecked then hit restart and the phone won't restart. I have verified this on my two Sensations.

[Q] Phone won't stay in download mode?

I'm having some weird problems getting the phone into download mode. If I hold down voldown + power + trackball, the phone goes into download mode and is recognized, but then leaves download mode about 5 seconds later. The screen goes black and the charging screen turns on for a few seconds and then also goes black. If I just plug in the phone to charge, the charging screen turns on for a few seconds and then cycles with a black screen.
Is there something up with the charging circuitry? Is it possible to get the phone to stay in download mode?

Try doing the forced download mode method

Are you talking about the volume down + trackpad? Same thing happens, download mode screen flashes for ~5 seconds, phone turns off, starts flashing charging screen.
I also have a download mode jig, but that isn't working either.

Also, new development: the phone won't even turn on now when I hold down the power button. Bad battery?

No he means pull battery, connect usb, hold power, volume up, volume down, camera, and tackpad and insert battery. It should FORCE the phone into download mode.

That works, but I still get kicked out of DL mode after about 5 seconds. The issue was never getting into download mode--all button combinations work for that--but the problem is I get kicked out of it after a few seconds.

Hmmmm. I think its probably a bad battery.
Sent from the phone everyone has forgotten about!

Alright. I'll definitely check that out and get a new battery.

Got the battery today. Unfortunately, still the same problem! The Sidekick boot screen now displays in place of the battery charging screen, but I still get kicked out after 5 seconds.

Damn, well the only thing I can think is a problem with the board not receiving enough power. But I don't know, maybe someone else can help you better.

Another thread reminded me...
Fixed the problem! Seemed to be a ribbon cable or some sort of loose connection. I opened up the phone (all the way), removed the RF shield, unplugged all the ribbon/connector cables (minus the one for the camera) and removed the whole board from the phone case. Checked the connections, put everything back together snugly. It now works like a charm.

same problem
would you make a tutorial on how to do this ?

Yeah i had the same problem iv been trying to go into recovery mode and safe mode. I cant do it im having the same exact problem. I get kicked out every 5 seconds but Redct has a point. There may not be enough power going to the phone. I may attempt at taking the phone apart extremely carefully. If this works ill post then its a manufacture problem for not assembling the phone right or not finding out that people do lots of things with their phone and the phones is just a bunch of computer componets wraped around a piece of plastic. Better quality phones must be sturdy.

So I attempted to take apart the phone and put everything back together and successfully booted. I it booted into the Android OS but then for some reason crashed and entered the boot loop again god this is irritating

Same Problem
I am having the same problem. I took the phone apart, but I couldn't figure out how to get the circuit boards out to unplug the ribbon wires, can you tell me what to do? I had the same problems a few weeks back, but it was staying in download mode then, but now it won't stay in download mode for more than 5 seconds. I got a new phone because of it(LG Optimus). I would really like to get my Sidekick going again though!

Try using heimdal n enable flash bootloaders n hold the volume keys

I'm attempting this fix. Got arround taking out the board and just need some help with what to do with the RF. I can't simply take it out and put it back, my guess. Any help is appreaciated. Like what kind of tool would I need for that? Thanks!
The RF shield or the RF 5000? I'm confused.
BTW... If anyone needs help with how to dismantle the phone, follow this thread. It can be found in General section.

I know this forum is ancient, but I'm working on an E-Bay phone with this exact issue. I found the following thread the most useful and informative on the problem:

Phone won't boot

Hey guys,
My phone shut off unexpectedly today and now won't turn back on. When I try to power it on I see the Google logo for a couple seconds and then it'll just shut off again. I tried holding the volume up/down buttons to access the bootloader, but right after I get to the screen it just restarts itself again.
Connecting to power (AC or USB) causes it to constantly reboot over and over, it just shows the Google logo for a couple seconds and then restarts again.
Any ideas on what I can do?

Provide more information for a starter - stock? unlocked bootloader? rooted? third party recovery? rom and if yes which?
If it's stock I'd RMA it.
If not what did you do immediately before the problem started?
try holding the power button for > 2 seconds which should turn it off completely, leave it on a wall charger for at least a couple of hours then turn it back on - I doubt it'll fix the problem but it's a simple thing to try...

Everything on it is stock, no ROM, not rooted. I had just taken it out of my pocket to check the time, put it back in my pocket and then felt it vibrate, took it back out to see it at the Google logo and haven't been able to get it started since. There was one or two times when it got past the Google logo and started to show the start up animation (the four colours bouncing around or whatever it is) but then it shut off again.
I tried holding the power button to completely turn it off, but plugging it into the wall charger just causes it to repeatedly attempt to boot like I mentioned earlier. I'll leave it for a while and hope for the best

Sounds like the mobo is bad. Most likely will have to rma it.

Do you have a case on? The case could be faulty.

Maybe not. Sounds like a stuck power button to me.
OP does the phone just endlessly repeat this cycle? If so it's rebooting itself do to a stuck power button. One other users already reported similar issues and his power button was indeed stuck. Mash the power button hard for a minute to see if you can unstick it.

You got it!
Thanks so much, really wasn't looking forward to waiting for weeks while the RMA went through. The button didn't appear to be stuck - it was still clicky - but after mashing it for a minute it started up normally and appears to be fine now.

Did you flash any ROMs or anything previously?

brother the issue is gone, as mentioned "sticky power button" was causing it. read the thread before posting. btw thanks for effort anyway... haha
:laugh::silly:

Hi all. Sorry to reopen an old thread (but xda suggested I check here before making my own thread).
I think we have the exact same problem with a Nexus 5. Unfortunately, bashing the power button doesn't seem to be helping (and makes me feel slightly silly .
Anyone know how much effort it would be to take it apart to get to the part that's stuck? Any good instructions?
Thanks.

Weird, I have the same issue starting a few hours ago. I updated to the Oct 17 beta of Cataclysm then a hour later it happened. But was told it sounds like the power button issue.
Took it apart, tried to fix it. If plugged in I can get into the bootloader, but then it reboots again. I've tried tapping it on a hard surface, and it gets seems like it almost fixes it because it'll connect to my laptop but then reboots again.
Could it be the battery? It was fully charged but then died as I was deleting hundreds of photo's in Dropbox to move photo's over from my phone because it was full.

I too am running into this same issue. My screen cracked so I replaced the digitizer with some success. In the process I damaged the battery and needed to replace it. When I got the new battery and replaced it my phone is now unusable.
When unplugged: I turn on the phone and it's running the ANDROID animation then turns off.
When plugged in: I turn on the phone, the ANDROID animation runs then the phone restarts and continues the process over and over again.
I then flashed the phone with Marshmallow and the same thing happens. Except now that I flashed it I get the Android icon with the spinning gear. So; I flashed it back to 5.1.1, but the same result.
Could I have physically damaged something inside or is it a battery issue? Thanks for any insight.

Phone doesn't turn on unless it's plugged in and then it keeps rebooting every 2 seco

My phone has been acting weird the past couple days. It would randomly reboot but when it rebooted, I would have to hard reset it for it to completely boot up. For the past couple days it would happen a couple times a day. Today it was doing it almost every hour. I was just waiting to get home from work so I could back up the phone and wipe and then it just turned off. I couldn't get it turned back on. When I plugged it into the charger it turns on the Google logo and then reboots over and over again. When I unplug it, it shuts off. I can't even get it to boot into recovery or bootloader because it keeps rebooting every couple seconds.

Just a guess, but I think you're power button is shorting out. See what others think.

Yea I've seen it in another post. That doesn't explain why the phone keeps rebooting as soon as I plug it in. But I have noticed that for the past couple days, the power button was becoming really sensitive as in I would hit the power button to turn the screen off and then it would immediately turn the screen back on. But if its a hardware issue then there's nothing I can do but contact Google to send me a replacement.

I think as soon as you plug it in the battery gets enough charge that it boots but then the power button shorts out and it reboots

I tried tapping on the phone by the button and it turns on the phone for a little bit. Same thing if I wiggle the power button. I'm convinced that's the issue.
