Bootloop - Android Q&A, Help & Troubleshooting

Hey, so, firstly I have a blue life one x. I love the phone and haven't had any problems until now.
I got an android update and my phone restarted, which has happened with the last two updates I got, so I didn't think anything of it. However, my phone was practically dead when this started and it restarted and got to the screen where it says "Android is starting... Optimizing application 1 of 143"
It would get to around 100 and turn off, restart and get to about 100 and turn off again.
I googled around and found a thing called bootloop. By what now seems to be a stroke of luck, my phone eventaully charged to about 40% and I got it to turn on and everything was fine but a few days ago, it died again and I ran into the same problem.
I went back to the boot loop instructions and tried it to no avail.
My phone has a fixed battery, so removing it wasn't an option. I left of the phone off the charger for 30 minutes and held the power button for two minutes(to discharge any remaining power?). Plugged it back in and it went right back to trying to boot back up and optimize apps.
I then removed the case, detached the ribbon that connects the battery to the board, held the power button for two minutes and let it sit for 3 hours. I connected the ribbon, plugged the charger back in and it instantly tried to boot up back into the optimizing screen and turned off.
I did all this again but left it for the past two days and now its back to rebooting over and over...
Things of note:
The light indicator turns red when the phone is connected to a charger, whether the battery ribbon is connected or not.
When it displays the blu splash screen, the optimizing applications screen, or recovery mode, the light indicator is off.
I can get into recovery mode, but I can't do anything before the phone turns off and reboots again.
Any help would be appreciated!

Eh?! Photon won't turn on anymore. White LED when plugged in?

My photon was on 5% about an hour ago... then it turned itself off. I plugged it in to the charger and a "white/faint yellow" LED comes on. Normally the photon doesn't have a charge LED so this certainly struck me as odd.
It has been sitting for almost an hour and still won't turn on.
I took the battery out and reconnected the charger and the white/faint yellow LED comes back on, even with the battery pulled out.
What is happening here? Has anyone seen this?
I've see green/orange/red LED flashes for diff things but never white.
Well I found this thread: http://forums.androidcentral.com/sprint-photon/107931-led-not-working.html#post1147045
Looks like white means very low battery and charging. Now the white light has gone off while plugged in... But it still will not turn on
Turns out, I was plugging it into a PC usb that didn't have the drivers installed. The phone won't charge if the moto drivers are not installed, regardless of the light
I plugged it into a wall charger and viola... its back and running.
False alarm!
Lol, exact same thing happened to me! I totally freaked out, but plugged it in a wall and started working.
same thing happened to me yesterday. I plugged into the wall, NOTHING. I started freaking out, until I pulled the battery and re installed it. LED charge light then came on and all was good. Weird.
Can someone help me i have a photon also but when i plug it up it says failed to boot 2 starting rsd mode battery too low to flash and it wont boot up when plugged up to a computer. also when i plug it into the wall it just boot to the m sign

- Pull battery
- Put it back in so it's off
- Keep it plugged into the wall to charge it
- Once charged, power into RSD mode (power+vol up)
- Plug into computer and start RSD and flash 154_5 SBF to get back to stock
- then flash 198_7 SBF for good measure.
- Reboot
When i try that nothing works, it just stays on the white led light
I just bought mine from best buy and it did the same thing..they exchanged the phone since it was defective..

Photon won't turn on anymore. White LED when plugged in
i have a refurbished replacement photon from best buy geek squad that i got last month. within a few days it was acting strange and randomly/often turning itself off. the battery was fully charged yet the unit would often times power down. this happened a lot the first few weeks. then last week the issue seemed to stop and it stayed on 24/7 as i charged it frequently. all was well until yesterday.
i dropped my phone from about 2 feet. the phone turned off and only the "m" boot up screen appeared after i powered on, then it went black. i had a fully charged battery in the unit when this happened. i plugged the charging cable into the phone and it kept booting up to this static "m" screen then turning off. the LED notification light went red and after numerous times powering on and off and resetting the battery (and sim card) i finally got a "5%" battery screen. a few seconds later it showed 100% battery then kept rebooting to the static "m" screen and shutting off again. then i started getting a "?" screen for the battery a few times and back to the 5% and it changed to 80%/100% very quickly and back to the blank screen. i left it plugged in overnight.
now the LED notification light turned white and the phone cannot be powered on. i tried another battery without any success so that shouldn't be the issue.
any ideas what to try next?
same thing happened to me.

Try to fully charge your battery using portable battery charger.
When battery full charge, try to entering recovery mode. From off condition, press both power and volume down, press down until you find android recovery and press volume up button. After you see exclamation logos, press both volume up and down. Then select wipe data. Hope fully you can still entering recovery mode.
If you cannot enter recovery mode, try to enter RSD protocol.
step is, connect your photon to PC using cable data, press both volume up and power, wait until it show RSD Protocol, than flash it again.
How to flash using RSDLite is in development section, you can read there.
Hopefully its can work

Hard Brick/Black Screen 5.0 [SOLVED]

My 5.0 is hard bricked. Black screen, won't charge, won't turn on. When plugged into outlet or computer, still black screen.
I rooted it back in December with no problems until today. Decided to plug it into an outlet to charge it since battery was around 50%. After about 30 minutes, used it to check weather, etc., then I did a quick push of the on/off switch to turn off the screen. About 2 minutes later, went to turn it on and got the black screen. I decided to leave it plugged into an outlet for about 1 hour and still nothing.
Looking at other, similar, bricked posts for the 5.0, doesn't seem applicable to this completely dead device (wasn't installing a rom or doing anything unusual).
Any help is greatly appreciated.
Solved
I was able to fix the problem, without losing any data, by going into recovery. For others who may run into similar issues, I did the following:
Pressed the power and volume up key simultaneously for about 10 seconds until the SAMSUNG logo appeared.
Selected 'reboot system now' and pressed the home button.

[Q] Sleep of death (won't turn on)?

Anyone getting the sleep of death on their XTZ2? I'm running completely stock (not even rooted) on 23.0.1.A.4.30 and just experienced the unit not turning on at all until I do power + up volume.
Upon returning to life, the battery was 90%, so it wasn't battery.
Had a bit of a panic attack until I googled the solution (power + up) but this is the first time its happened to my unit, could it be related to the recent upgrade to 23.0.1.A.4.30? Anyone else seen this?
Mine lasted a day and a half after the 23.0.1.A.4.30 update and then became very erratic and kept forgetting wifi login info.
Did a restart and certainly got a sleep of death OK.
Would not switch on at all.
No power + vol up or attempt at repair via PC Companion made any difference to it.
Since gone back to Sony for repair, that was weeks ago, who knows if /when they will return it.
I had the same problem with mine as well I have the 561 the Verizon model. I have received a replacement but have not been able to get it to turn on either. It shows no signs off life at all not even when connected to power AC or PC. My old one would blink red and go dead when connected to a PC but this one doesn't even do that. I haven't had time to call for another replacement yet but really two defective devices in a row the second one didn't turn once.
Finally got mine back from Sony repair agent.
Worked fine for 3 days, then failed to power on again as per original fault.
Once again returned it for repair.
Think I'll give up and buy an iPad instead - at least they seem to be reliable and consistent.
This just happened to my tablet this morning. Tried all options under the sun but can't get it to boot.
I can't even do a factory reset and I don't particularly want to return it under warranty.... :'(
Mine is an xperia z2 tablet sgp561 (USA Verizon) build 17.1.D.0.437, stock 4.4.2. This issue happened to me 5 days ago after I powered off the tablet, it won't turn on again. Battery charge was ~70% at the time. Plugging it with factory Sony usb charger won't do anything, charging status LED remained Off, power button unresponsive. I let the tablet sit for 2 days without charging cable connected hoping the battery will drain completely by itself and the buggy firmware will restart executing at its base address getting out of the bug. Then I connected the crap to a fully charged 15000mah Anker power pack and alas, the charging status LED glowed red and after ~5 more minutes the LCD screen turned On for ~5 seconds showing a big battery icon at the center of the screen indicating 0% charge. Waited about 1 more hour and the charging status LED turned amber. This time I did the "power button + volume up" ritual holding both buttons for 10 sec+, expecting 3 vibrations but didn't feel any. At this point the tablet is still powered off. Because LED = amber, thinking battery must be at least 10% charged by now, just pressed the power button for ~2 sec and surprisingly the normal power On vibration came followed by Sony logo on LCD screen and the rest is normalcy.
From what I can remember, the recent change I made before this problem happened was turning Stamina to On in the battery settings (factory default is Off). I reset all settings back to factory defaults and so far so good.
Finally got mine back from Sony repair agent after about 3 week wait.
Seems to work OK now, fingers crossed it will keep working this time.
The note that came with the return indicated that they replaced the mainboard and battery, which is a better solution than their first attempt which was just to reflash the software.

Dude same thing, WTF is going on, I tried plugging it into charger, nothing. And once I got the msg of red colour battery icon and then I plugged it in. then it started charging and I was happy so I turned it on the it wasn't charging,
Please update me what happened and what they are saying cause I am about to send mine to get it fixed.
Edit: seems that by replacing the battery and mainboard has actually fixed the issue? Guess it's time to send it back to them, Gosh

Did this method work for you? Plus did you come across like it was charging but it wasn't really charging,(like it showed the low battery stat with orange/red colour LED notification but suddenly it vanishes) then it's not responding at all.??
I had this issue 2 times with months in between , no response from power+vol up , no lights when charging , no response from pressing on the red button behind the flaps.
The last time it happened i tried putting it on the charger for a whole day with no result, then decided to let it rest a few days first , since someone had the same issue and it magically came back to life when he got back from a vacation.
So i try to turn it on 2 days later and the tablet to my surprise responds again with blinking red LED, recharching afterwards did the trick and worked again since
In my case i was running CM11 at the time, both times it happened after an update which required a reboot while, still mistified about the cause and the fix , i presume it solved itself by letting the battery drain.
Since then i reverted to stock rom just to be save but havent had it happen since, this also seems to have fixed some touchscreen problems i was having at times.
Hope this helps.
Bloody hell, I've just ordered mine today!
Don't stress. Mine got repaired. if it goes tits up that's what warranty is for
What did Fonebiz indicate was wrong with your Z2.?
They replaced the motherboard in mine.
Exactly the same, works fine now
This just happened to me today. So seems like overall suggestion is to try and let it discharge. The try to start it back up and charge it then. Just want to make sure that's the only potential solution now?
No! Leave it powered off, put in on a known good charger for at least 12 hrs. Don't touch it in that time.
If it does not come alive after that, send it in for repair.
ok..let me try that. I originally tried that and nothing occurred. However, I just found the OEM charger and usb cable and will try that. Unfortunately it's a Verizon version so sending it in will not be covered by Sony warranty. Per the Customer Service that I called.
ok..tried another charger and the red light came on, but it's been over 12 hours and still no go. I did notice that the red light was no longer on (from overnight charging). I left it unplugged for a bit and reconnected. The red light came back on but still no response. Sounds like i'll need to send in?
Looks like it.
Had the same problem on tuesday. Impossible to switch on, no light, none effect with charger, none effect when connected to PC/MAC etc...
After 4 days without charging my Z2, it came back to life, showing only a big red battery icon when pushing some seconds on the power button. Connected to a charger the red led indicator glowed ! (red battery icon is totally different with the original icon when tablet is charging in power off mode)
After a full battery charge with OEM charger and after a normal power on, my Z2 is now perfectly functionnal.

Got wet - stuck in boot loop

So I picked my Umidigi phone up with bleach covered gloves and a bit must have got inside.
The phone now, when the battery has charge, repeatedly shows the boot screen (the logo) for a couple of seconds, and then goes dark for about 5 seconds. This repeats until the battery is completely dead.
When I plug it in to charge, the red light comes on - and then into the same boot loop.
If I play with the volume controls while this is going on, I can get the boot selection screen to appear - normal/bootloader/something else - I can even choose different options on there, but then the phone goes off again.
If I plug into my Pc, it connects and disconnects repeatedly - the connection doesn't last long enough (2 secs) for the Pc to identify the device.
So, I'm not interested in saving the phone, just the data - the camera was broken anyway. I've taken the back off (no easy feat) and left it in rice for several days - made no difference.
Any suggestions on what I can try next?

Phone doesn't go past the Boot logo

Tonight I left the phone charging when it was at 10% and woke up to it stuck on the start up screen (HUAWEI with 'powered by android' in the bottom with the black background).
If I try to shut it down with the power button it goes black for a few seconds and then restarts again by itself, but gets stuck again in the Huawei logo screen.
I noticed the phone charger wasn't working too well before this happened (it kept stopping to charge if I moved the wire a bit) so it might be related.
Anyway I tried charging the phone with a different charger for 3 hours, but nothing happened, also the LED which shows how charged the phone is doesn't work but I still think it charged because it was getting warm.
Then I tried to go in 'Recovery mode' with Power+Volume up while charging, and 2 rectangles, one magenta on top and one blue on the bottom, with a green background appeared (like this but the red square was hot pink). Nothing happens while in this screen, so I shut the phone down and it restarted, going back to the Huawei logo.
Right now I'm waiting for the battery to exhaust and see if that does anything.
Anything I can do? It's okay if I have to do a Factory reset and lose my data, even if that sucks, but right now I can't afford to buy a new phone :/
