I am very sure that there are all sorts of variations on this but I am sufficiently clueless to need a whole new level of hand-holding. I have a Lolipop level Nexus 5. Never did any modifications. On 7/10/15 I turned off the phone and turned it back on a few minutes later. Google was displayed and it started in with the 4 spinning colored balls..... It never gets past this (is this a bootloop?). I can let it stay in this pretty hypnotic display until the battery is dead... hours and hour. I tried the power down, power up and volume down to get to recover mode ... then the power and volume up to get to wipe and delete phone, it says it completes. Rebooting leaves me in the same condition. I have had the phone for just over a year and never had any issue. It is in prime condition, hardly a scratch.
I need someone to hold my hand and tell me everything is going to be alright. And please, what do I do? I see other posts about partition corruption ... how do I check if this is the issue? If it is the issue, I'll tell you right now, the solutions talked about are well beyond me.. flashing this and editing that and boot to adb and spinning in place, chanting naked during a full moon.
Any body feeling like helping a lost soul?? Beg beg.
Additional info and concern.... Just noticed that what I asked the phone to do is 'wipe date/factory reset' . It responds with :
-- Wiping data--
Formatting /data...
Formatting /cache...
Data wipe complete.
That is all it says, is that the correct sequence? It doesn't say anything about the cache and factory reset. Clueless. Thanks.

Hi All,
I've recently updated my Desire S to CM10.1 using a ROM off here --> [ROM][XXYYYZZ][UNOFFICIAL] CyanogenMod 10.1.
Everything has been running fine until I found the "Simulate Secondary Displays" button under Developer Options and decided it would be cool to see what it does...
The kicker:
a) Screen is now stuck exactly where it was on the Developer Options prior to selecting a screen resolution
b) Holding down power button for any period of time does nothing
c) Holding down Volume up + Volume down + Power for any period of time does nothing
d) The computer recognizes the phone as it makes it's lovely "new device found" sound, but stupidly, at some point I've disabled USB debugging so can't use adb to reboot as it returns authorisation error (The authorisation option doesn't pop-up on device screen as it's frozen).
I've read about this exact problem happening on other phones after selecting this option but they all seem to be able to use either b) or c) to get back to bootloader to reflash the ROM.
So, my question: if I let the battery die, what are my chances? I've read myself out of pulling the battery due to eMMC issues. Unfortunately the damn battery was mostly full so could take a long while to drain :S
Thanks!
So let the battery die (takes about a day), boot to recovery, wipe data (or figure out where this setting is stored and delete the relevant file), no problem. I don't see the issue here.
Pulling the battery out doesn't cause eMMC issues. The problem is caused if you pull the battery out and then put it straight back in. Remove the battery, leave it out for a minute or so and then put it back in and manually boot into recovery.

Ah, that's interesting. Is there any reference material available to explain why that is the case? What is physically happening here?

Apologies, it wasn't a particularly open question. It was more out of frustration that there is an option available that will always freeze the phone when it isn't supported on the device.
I let it die then used recovery to clear cache and davlik cache and booted fine until freezing on the "Optimising apps" screen. Let it die again, clear all data, clear cache, clear davlik cache, restore nand successfully.... Boots to HTC then black screen, no response to anything, same as when it first froze.
EDIT:
Repeat same process but clear cache and davlik cache after nand restore... black screen, no response. Cant even tell if it is actually doing anything. Charge light doesnt come on when plugged into pc whilst on black screen.
All I can think of now is flash the CM10.1 ROM again or maybe restoring the original nand from before CM10 but will have to be after work. Is this behavior indicative of a larger (potentially physical) problem?!

From what I remember - there was some in-depth discussion on one of our threads about 18 months ago - the actual cause is that re-inserting the battery while the circuitry is discharging causes a spike which can be high enough to blow the eMMC.
Just to let you know, reflashed CM10.1 ROM and all is well in the world again Thanks guys for replying!
However, NAND restore did not work. As the NAND backup is supposed to be the be-all and end-all for phone recovery, should I be concerned this failed?
My tablet froze on me and I powered it down to restart it and then it went into what folks on here call a bootloop. After holding down Power and volume down, it brought me to a screen that had three icons and I chose the one on the right by mistake and now it's looping again, but instead of the Asus screen with the refreshing icon, it's the android falling with an Error on his chest after quickly flashing Installing System Update.
The power volume combo works no more and the only way I can shut off my tablet completely is to use the power and volume up button. I can't get back to screen with the three icons no matter how many times I try.
I've already resolved myself to purchasing a new device, so my main concern is recovering the data, slim as that might be. Any recommendations?
Also, note that Ive never rooted or installed anything on my tablet. No roms or kernels or any other modifications. If I can get my data by any means necessary, I'd be satisfied, even If I Ihad to open it and retrieve the harddrive.
Hopefully Ive explained myself sufficently for you guys to help me. Cheers.

If I read your post correctly, you selected the right icon which is a Wipe data from your bootloader. When you executed that Wipe data, it will wipe everything on your internal SD including your /media folder or your personal files and data... The chance is very slim unless someone knows how to recover data from a wipe. Technically, your data is still there but it is only a dumb files which contain only 0's and 1's. Some recovery tools may be able to retrieve your data but I don't have that knowledge.. I hope that someone will be able to help you out and good luck...:fingers-crossed:
I'm afraid LMK is right: Your data is gone.
Do I suspect correctly that you interrupted the Wipe Data process after selecting it "accidentally"?
Choosign Wipe Data from the bootloader causes the BL to write a command to the misc partition to start the recovery and wipe the data partition. If you interrupted the process, there's no telling what and where that got corrupted - unless you just let it loop and pray that it finishes the wipe process which would erase the BL command. Connect it to power and let it loop for a few hours. What have you got to loose?
But your data is gone either way - sorry.
Morning, cheeky question(s)
Where are you located, and would you be interested in selling your bricked TF700? I have a broken screen among other things and would be interested in buying your tablet for spares if you are getting a new one?
PM me if you are interested.
Thank you
Freddie
I'm not all too sure what the Icon on the left wad, but I'm sure it said RKU or some sort. I would have given up all hope if I had hit the wipe data on the right.
Days recovery aside, is there anyway I can get my looped tablet to work? I plugged it into a comp and it didn't recognise it.
A couple of months back I decided to root my device. I did this using the unlocking the bootloader method. As a result, I lost my DRM keys, and I managed to restore DRM function by following the methods detailed here: http://forum.xda-developers.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672
I had to download the stock Android 4.4.4 from online, which I flashed my phone with - no problems. Things ran smoothly from then for about a month, and then I realised that my cellular network started to malfunction, and I couldn't access apps like YouTube and Snapchat on the cellular network. This prompted me today to do a "soft reset" of my phone, by holding the power button and volume up button simultaneously for about 3 seconds - under the impression that it would restore my phone settings back to the factory default.
Much to my horror, the worst case scenario happened. When I performed the soft reset, my phone vibrated 3 times and switched off. When I tried to turn it back on, it would show the boot-up screen indicating "SONY", followed by the next screen indicating "powered by android", and then it would show the blue screen with the wavy lines. It stayed on this screen for about 20 minutes. I figured something was wrong, and I tried to soft reset it again, only to be stuck at the blue screen once again. I decided to let it stay that way for 2 more hours, in order to drain the battery. When the battery drained, I turned it back on, and it was still stuck at the blue wavy screen.
I don't know a whole lot about Android phones, and I have no idea why this is happening, but it is causing me an immense amount of frustration - I have invaluable data on that phone, and to lose it would just be devastating. I can't even begin to describe it. I'm using TWRP recovery, and I'm also using TitaniumBackup which is backed up onto my phone's internal storage, and I can't access any of the files on my phone from my computer, because it doesn't recognise my phone.
This has been a long one, thanks for bearing with me. I've got a few questions:
1. What's the problem that's preventing my phone from booting?
2. How do I fix it?
3. If it's unfixable, how can I retrieve my data from my phone?
Really, really hoping someone can help me out on this - I'm completely lost and am desperate here. Thank you in advance!
Can you boot into TWRP's recovery mode using the volume down key?
Just press volume down when you see the green light on your notification led upon powering on your phone
Well something keeps the phone to boot, try to clean cache in recovery, it might help.
But to restore data on internal storage, count it as unpossible.
UPDATE: I was able to fix my phone using Eross's guide 'http://forum.xda-developers.com/google-nexus-5/help/nexus-5-stuck-boot-loop-lollipop-t3098632'. Very relieved and thankful. Good luck and hang in there.
I'm learning my way around slowly... posted incorrectly to XDA Assist forum. This appears to be the more applicable forum, so here is a copy of earlier appeal:

Any body feeling like helping a lost soul?? Beg beg.
Additional info and concern.... Just noticed that what I asked the phone to do is 'wipe date/factory reset' . It responds with :

Formatting /data...

Data wipe complete.
That is all it says, is that the correct sequence? It doesn't say anything about the cache and factory reset. Clueless. Thanks.
Also... saw something saying to run fastboot clear cache , I've downloaded and installed an Android SDK for windows. Getting way over my head I'm afraid.
Left it to charge over night and when I looked at in the morning it was stuck on the samsung logo screen, Holding power button down on it's own does nothing and I have to hold all 3 and do a complete power down, I can get into the recovery menus sometimes but it will freeze again before I can do anything with them,Any way to fix this? I haven't tampered with the device in anyway either.
Oi Mate...
first of all, important:
For a Power Reset you push Power-Button and Vol-Down and keep pressed until it resets. NOthing more, nothing less.
Try to get into recovery to try some wipes (Data, Cache, Dalvik). Be warned: Data-Wipe means clean-wipe. ALternatively try to get in into DOwnload-Mode to see if you can flash a stock image.
YOu still might be unlucky. Now the time is starting where lots of S6's have 2 years or more of heavy duty behind them, so the population will definitely start to decrease. Good that I have 3 of them... Returns from colleagues from work meant to be thrown away .... NOT!
Silly me but that is what I meant anyway, Only managed to get into recovery once and it froze just as I managed to select cache, Will attempt a few more times then just accept it as a lost cause, Had the thing since August 2015 anyway.
