[Q] hardware or software issue?? - RAZR HD Q&A, Help & Troubleshooting

First off, i apologize if this is been addressed, but if it was i couldn't find it.
my issue is, my power/volume keys are real touchy...like i have to REALLY press them to get them to work. The funny thing is, when i go into fastboot or recovery and use the hard keys then, they work no problem,
before i factory reset and/or fastboot to stock, i wanted to see what you all thought.
Thanks

maybe....

it depends, ive always pressed the powerbutton hard because i have a tpu case, and sometimes it lags to wake...same to raise/lower volume, seems like a sw thing hopefully kitkat with its lesser memory footprint will speed up our phones...

[Q] Is anyone finding it hard to access the bootloader in ICS on their 9020t?

Recently, as I was trying to update to the latest version of ICS 4.0.4, I found myself having to manually update to 4.0.3. I'm new to the Android platform and this 9020T Nexus S is my first Android phone, but I did manage to previously manually update to 2.3.6 from the 2.3.4 that was in the phone (apparently me and OTA updates are like oil and water). Unfortunately, I soon found out that I was working on erroneous information, and if I wanted to move to 4.0.4 while in 4.0.3, I would need to root the device, which is something that has been on my to-do list for a while now so I thought it'd be something I'd try.
Unfortunately, I'm finding that with ICS, I'm finding that it's a lot harder to access the bootloader than before. Holding the up volume key while also holding the power button while the phone is off tends to just tend on the phone, not get me to the bootloader interface. That's not to say that getting to the bootloader is impossible, but it seems that about 4 times out of 5 I just end up turning on the phone. I have put the thing inside a cheap case for protection, but I don't think that's the culprit, as the buttons are still clearly accessible. I imagine that the extra overhead from ICS 4.0.3 is perhaps enough that getting to the bootloader is rather difficult somehow now, so to that end, has anyone encountered this problem before? What did you do to try to sort this issue out?
What kind of case is it? I bought some argyle case from Amazon that made it damn near impossible to access the BL when I needed to. I bought a cheap silicone case and I can use the buttons no problem. I had the official OTA and flashed custom recovery and didn't have any problems rebooting into the bootloader. I would at least try to boot into the BL without the case just to rule it out. Also make sure you hold the volume button down until the screen for the bootloader actually loads up. I've let the button go a few seconds early and just booted up normally.
It's one of those cheap ebay hard cases that I bought online, can't post the link here thanks to anti-spam protections. I doubt that's the culprit though, I can reach the buttons on my Nexus S pretty easily since there are cutouts for the buttons. If all else fails, I'll try to see if I have an easier time with the case removed though.
Are you holding the volume key first? This has nothing to do with android, updates, rooting, etc. Maybe your power up key is biting the dust?
I think I'm mainly trying to press both at once, though I have tried pressing the volume first. Will try again to be sure.
As for the power button going, I doubt it, this is a relatively new device that hasn't given me any trouble power button wise before. Will have to try again specifically with that step though.
Ok, just tried this again. I didn't get anything conclusive out of it, though I did manage to get to the bootloader screen twice in a row. I think what's going on is that I'm not pressing enough of the (really rather cheap feeling) volume rocker to access the bootloader. Those two times stemmed from me pressing the entire upper half of the rocker rather than just the tip, so maybe it's not quite registering with the phone.
Unfortunately for this experiment, right after this experiment I checked for an update on a whim and it found a 4.0.4 OTA update . Been waiting to get that done for about a week now, so I'm glad even though my technical abilities have failed in my this case. Will continue to see if I can't get this thing rooted though!
you may try using fastboot via your computer...
Code:
fastboot reboot-bootloader
I'm actually trying to root this thing with one of those one-click root programs. I think I've got the bootloader unlocked but it's giving me a "device not found error", even though I've got the phone rebooted for a while now.
Kinda scared that I'll brick the thing if I disconnect the USB cable connected to it.

[SOLVED]Jelly Bean update broke power button?

Hi,
I recently received the OTA update for Jelly Bean, and I upgraded with no problems. However, now, my power button is only working when it wants to. If press it a bunch of times, it might turn on if I'm lucky, but most of the time it doesn't work. Right now, the only way for me to activate my screen is by connecting the charger, or asking someone to call me. The only way to turn off the screen is to wait for it to turn off! As you can imagine, I am quite PO'ed by this problem.
Has anyone run into a similar situation? It seems like a software issue to me because before the update, the button was working perfectly. Everything is stock, by the way. I was on CM9 before the update, but I flashed to stock ICS so that I could install the OTA update. I don't have the clockworkmod recovery anymore either.
Please help!
UPDATE:
I did a little hack to fix it, at least temporarily. Not sure how long it will last now, but at least it didn't cost me any $$$.
quoting myself from below:
I couldn't figure out how to root my phone without a power button because I'm a lazy guy and a work-around just isn't worth the trouble imo. So, instead, I decided to just open it up and see if I could fix it....and I did
First things first though:
I AM NOT RESPONSIBLE FOR ANY DAMAGES TO YOUR PHONE THAT MAY ARISE FROM THIS METHOD!
It's not a permanent fix, more like a hack, but a hack is better than a work-around any day. What I did was find the button on the motherboard, and then 'pinch' it with a small pair of pliers. My original fear was that the problem lied elsewhere on the phone because the actual button seemed to be clicking properly, but it's pretty much impossible to figure out what else the button is connected to and fix it. Luckily, pinching it made it work! I guess that the clicking mechanism isn't the same thing as what makes the contact in the button. If you are going to try pinching it, try not to pinch too hard. I did it a little too hard, and now the button doesn't come out as much as it used to, so it doesn't feel as good as the volume buttons. I'm pretty sure you just need to squeeze it enough so that it gets squished enough to make contact when you press it. Squeezing too much could almost definitely result in destroyed button.
So if anyone has the problem on their phone, and doesn't feel like paying a bunch of money and waiting a long time for it to be fixed, you can try this method to fix it (probably temporarily). Only problem, I guess, would be that you'd have to be more careful with how you treat the power button from now on. If you are good with a soldering iron and working with tiny components, you can probably find a new button on the internet and replace it yourself.

Sounds like infamous broken power button, which our phones suffer from.
Check this for a workaround.
Happened to me too. I tried to comfort myself into thinking it was a software problem. If your bootloader is unlocked and you're rooted, boot into recovery using Quick Boot and try to flash another rom and see if it solves anything. But I'm not hopeful. Most likely your power button just decided to give way.
https://play.google.com/store/apps/details?id=com.siriusapplications.quickboot
For now, if you set the lock screen to 'none' you can turn the phone on if you press the volume buttons.
If you're using a custom rom, I'm sure there's a option to wake the device using volume button under the display settings.
If you're using cm10, you can add the sleep button to the power widgets.

Thanks for the reply guys. That's what I love about this forum: someone always has an answer to everything.
If the button actually broke I'm going to be very disappointed since I was trying to sell it to get a galaxy nexus. Horrible timing. :crying:
I Just found something weird. When I pull the battery, I can't power on the device with the power button, but if I connect the charger, then the button works. That is, it will power on when I press the button, not automatically when I connect the cable. Yes, the cable shows the charging icon, but it doesn't boot until I press the power button.
I still haven't flashed back to ICS to see if that fixed anything, but I'll post an update when I do.

hopefully samsung issues a patch or something, this is just sad. after I did the OTA my power button also S#1T the bed. thanks to all the people who came up with the suggestions above...

[Q] Phone keeps rebooting

Hello, today my phone keeps rebooting for no reason. It just reboots immediately after the Google logo shows up or during the flying balls animation. Once in a while it will be able to start, but then back to reboot loop very soon. I can't even use the "Volume down + Power" screen (sorry I forgot what it's called) because the phone will restart immediately.
I didn't install any new app today. My phone is unrooted and is on Lollipop 5.0.1. Bought it used last week after I hardbricked my Moto G.
Please tell me this is fixable. My Moto G is still lying in front of me. The Nexus better not join its brother.
I got the same problem here, all of a sudden it turned off and began this incredibly fast boot loop, I can't enter recovery mode because the fastboot screen goes off as soon as it appears. I'll try to figure something out and come back here. Thanks
I recently installed Lollipop 5.0.1 so it might be something with it too
Thanks. Please tell me as soon as you find the problem. I hope it's just a software (particularly Lollipop) problem and is fixable. It's incredibly frustrating to see 2 phones go down in a 2-week span. **** my life.
ok, so my phone turned on and I actually was able to use it for a while, until I slightly touched the power button (but didn't actually click or even apply force on it) and then the problem occured. So it's either that the power button became overly sensitive or a sensor malfunctioned (I'm a noob so forgive me if I sounded silly).

So, I was looking for answers and figured out it was a hardware problem, the internal power button was stuck. I saw some tutorials on how to disassembly the phone and managed to loose the button up a bit and now it's working fine. Sending it from the phone right now hahah
PS. I'm not a phone master or something, I saw the tutorial and got the motherboard out to fix the button, the worst part was unscrewing those tiny little screws, but it was kinda easy at the end.

That's good news. I don't have the tools to open the phone so I'll have to go to the repair shop next week. Please inform me if the problem somehow returns to you.

Nexus 5 restarting regardless of ROM

So I've tried factory wiping and installing a few different roms and no matter which one I go to I keep getting these random reboots. This is particularly troubling when I restore an older rom that I know I was not having this particular issue on.
It is making my phone pretty close to unusable since it will often go into an "Optimizing apps!" speil draining battery and taking an obnoxiously long time to reboot. Not sure what is up. Any suggestions?

Try with a clean flash (or the factory images) without user data/modifications and see if your RRs are still there.
Is the power button stuck by any chance?

The button will NOT seem to be stuck, even if it is, as the contact is made internally. My bro´s Nexus had this problem, and by the end it kept rebooting constantly because the button was making contact on its own. I fixed it by tapping vigorously at the area between the power button and the camera and that made it work.
A way to know if it is stuck could be to press the volume down key as soon as it restarts, if it goes into recovery, then there is no doubt the power button is stuck.
Don´t dismiss hardware problems, as many Nexus are affected by the power button issue and you already tried software solutions which didn´t work.
Hope you sort it out. Remember to use an app to avoid pressing the button so much, such as when waking the device. I recommend Gravity Screen, but there are many other options.

Holding down volume after one reset actually put me into recovery. Plus it's restarting at times in recovery now :/
I doubt it's under warranty since I got it in feb 2014 x.x

If you got it directly from Google, I'd try calling them up and asking for a replacement even if you are a few months off the warranty period, I have read some stories of them honoring warranties in order to get rid of stock. That'd be true even now that the new Nexus is supposedly releasing this year. Nothing wrong with trying, you might get a new, shiny phone.
That being said, don't worry, it's perfectly fixable. The part that gets stuck is not the button itself, but the part that goes into the motherboard, so don't bother fiddling with the black button. I managed to fix my brother's button by doing the following:
- Clean the area between the button and phone of debris or any dirt that could be causing it to be stuck. This is just to be on the safe side, as it is unlikely that it is the cause of the malfunction.
- Take the case off the phone if you haven't, and then put it upside down and tap vigorously with your fingers in the area between the camera and the power button. It might not work the first few times, but it eventually will release the part that is stuck.
- As soon as you can get it to turn on without rebooting itself, install Gravity Screen, or any other app that replaces the power button to wake up or turn the screen off. You are looking to use the button as few times as possible.
After doing that, his Nexus went for being unusable due to constant reboots to working fine. It's been almost 6 months since it happened so it is bound to work, just don't lose heart and patiently work at it. Tap a bit harder if it's not working. Let us know whether you managed to fix it.

I'm going to get in contact with google. I tried pushing down on the area between the camera and it didn't help much. It has started working again properly after a really peculiar work around. I just don't want to have to be super cautious of a button for the rest of the time i own my device :/

Well someone mentioned maybe trying to clean it out somehow. I tried canned air and that didn't do anything so I formed a seal over the button using my mouth and then proceeded to exhale. It has yet to give me any trouble since then.
Had exactly the same issue, reboots over and over again, couldn't boot to bootloader without reboot...
What helped for me was something I read somewhere else, don't remember where, was knocking on the back cover between camera lense and the power switch, did it 4 days ago and it works since than..

You can take the back cover off, and if you are careful there is no sticker or seal that would tell google you have opened the device. It is difficult to pull all the way off, the vibration motor is attached to the case back and comes off with it so it would seem stuck. You just have to keep pulling.

Pressing on the area between the camera and the on switch seems to help a lot of people it didn't seems ot have much of an effect for me. While my phone hasn't given me issues since shortly after I posted this thread I'm kinda worried I'm one drop away from the issue coming back

Yeah but you'd need to unscrew a plastic cover that is inside the phone. Phillips head screws, jewelers screwdriver size. Depends on if its dirt or a broken switch though.

Sorry to disappoint everyone but this is a widespread problem that google is aware of fro some time now. It's not the power button but it's burried deep in the software and appreas to have popped up right after the Lollipop 5.1 up date. Check out all the posts on Google
https://productforums.google.com/forum/#!topic/nexus/IJSOuc7gw0w[376-400]
While it apprears to be confined to the Nexus 5 I have had it happen with my nexus 4 just running stock L 5.1
I hope that casts some light on it
Weirdly enough, my power button works flawlessly on 5 and 5.1. Red 32gb from the google play store. I've opened the case multiple times and put Arctic silver knockoff heat compound in sloppily and without regard, no issues other than sprint screwing up their spark LTE rollout.

Sorry, I disagree. While some instances might be related to software, it has been proven that there is in fact a problem with the physical button getting stuck on Nexus 5 phones. You can check it online and will find lots of hits and even YouTube videos, most of them around the time before lollipop.
Best way to check whether it is software or hardware is to press the volume down key when your phone reboots by itself. If it takes you to the recovery, you can bet your cat that it is not lollipop's fault
So I'm suspecting that I have the wonky power button too but.....
I haven't been able to get it to go to recovery when pressing power down and I've defintely had a few restarts very recently.
More importantly, and something that I haven't seen anyone else post about; more often than not my N5 just shuts down. It's usually when I've doing something with the phone (today was flicking through my GPM library). I'll power it back on and it will boot cleanly and then (more often than not) power down again. Other times it will bootloop, but that's rare. It seems to me that if I let it boot up and then don't touch it for a while, it will stay up but I'm not sure that's consistent.
Anyone else seen or heard of the power button causing a powerdown instead of bootloop?

You will need to troubleshoot this the old-fashioned way. Have you installed any updates, apps, mods or anything recently?
Best case scenario would be that you flash a stock image without restoring apps, kernel or any mods. Run the phone for some time, couple of days or so, and be on the lookout for power downs or reboots. After that, you can try adding a few apps at a time and keep checking. If the phone reboots even with a clean factory image, then I'd have to say the hardware is faulty. Could be the power button, could be something else.
Try it out and let us know

Disabled power button but it reboots my phone if I touch it

Hello,
I have a Nexus 5 with Android 4.4.4 and CyanogenMod 11. Like always, it had been working really find untill today, when it started to reboot and entered in a loop. I found out that it was because the power button was broken and with the lightest touch, it would activate.
Searching through the Internet I found out that many people happen to have this problem. I tried to disable the power button editing a file that is found under /system/usr/keylayout/qpnp_pon.kl, where I had to simply comment the line where the power button was.
Now, if I click the power button it doesn't happen anything, like I was expecting, but after 30 seconds of clicking it, it shuts down and it reboots like if it was an internal error or someting similar that caused that reboot.
Is it possible that disabling it the way I did could cause any type of problem that made it reboot after touching it?
I know it's an internal problem or something like this because when I touch it, it doesn't lock the screen or show the power menu, so the button itself is kind of "disabled", but it keeps causing this problem.
Is it good what I did? How can I solve it?
Thanks!

I had the same issue unfortunately. My N5 is still at LG for repair and it's taking much longer than they told me. Which is good of course. Like most smartphones now though, a 10 second power button hold will forcefully reboot the phone. It's hardcoded in the phone and no matter how much you try to disable it through the OS it won't make a difference until the rogue button is physically taken off the motherboard. If you're in Europe though and your phone is still in it's 2 year warranty I would strongly suggest flashing a factory image, relocking and calling LG (or Google, if the device came from Google).
Hope this helps.

Well... It's been like three years since I bought it, so I guess the warranty is over...
And if I want to disable it, I will have to do it manually and disconnecting it of the motherboard, am I wrong? I guess I'll either have to live with this problem or buy a new phone... Today it's not my lucky day! Hahahaha
Anyway, thanks for your reply!!
Many owners have the power button issue. A competent cell repair shop should be able to replace it.

Yes, that's true, I've found a lot of people over the Internet with the same problem.
By the way, I could finally solve my problem; after searching for a while, I found a YouTube video that showed a peculiar way of solving it... And it actually worked!
Well, it looks like I cannot put the link because I'm under 10 posts :cyclops:
Well, here's the video code if anyone is interested: _QpSSCifxAw
The Internet is amazing! Hahahahahahah
Thanks for your replies!
Are you referring to banging the power button? It wouldn't work for my friend's power button. He had to have it replaced because it failed a multimeter test, apparently.

Yep, exactly!
Like the video said, I bumped my phone a little bit because the power button was kinda stuck inside the phone, and that really worked...
I was amazed! And I'm so happy it worked! No need of having it replaced. [emoji16]

How did you do that?

Just hit the phone into your hand so the power button gets unstuck.
You can see the video I mentioned above for a clarifying idea on how to do it.
