I have been trying to repair this phone, but the usual faults have not turned out to be the problem. This is the background on the repair efforts:
In my research I found 3 main causes for a dead touch screen.
1) Corruption of system software.
2) Failure of digitizer cable (hinge FPC)
3) Failure of digitizer screen (touch panel)
To check for #1, I flashed the firmware again (after a wipe). I downgraded to Android 1.5 because I wanted to root the phone and install CyanogenMod Android 2.2 Froyo.
This was a big mistake because I learned that when you don't have a working touch screen, you cannot get past the "Touch the Android to Start" screen.
So on to step 2 - replace cable (hinge FPC). I have a G1 parts phone that was lightly used in good condition before it was damaged. There was no damage to the sliding section, so I expected the hinge FPC to be in good condition.
So I installed the hinge assembly with its hinge FPC from the parts phone, but this did not work either.
So next I installed a new touch panel (digitizer screen), but that did not fix the problem either.
I had a chance to borrow a working G1 motherboard, and I was surprised to see that the phone was working with the borrowed motherboard.
So my question is whether my problem motherboard can be recovered with a software solution, or if these symptoms indicate a hardware failure.
I thought that a wipe followed by firmware flash would eliminate all soft system errors, but I am not sure if the wipe and flash really erase absolutely everything, or if there is something else I need to do to get it working again.
Thanks.
more than likly it was the point in the motherboard where the flex cable connects. try using some electronic parts cleaner.
i have ran into this a few times and simply replacing the motherboard has only helped a twice, when i cleaned it up it worked.
That sounds reasonable. I still have some Tweek. I'll give that a try. It worked with the same kinds of problems on computer sockets.
Okay. You are on the right track. When I went back to the phone, I actually got two taps out of the screen, which it hasn't done in a long, long time. (I was running keyboard only for a long time before I could take it down to fix it.) I attribute that to just disturbing the contacts with so many assembly/disassembly efforts.
After I applied Tweek to the joints, it ran well.... for about an hour. Trying again was no luck, so I don't think I'm going to mess with the contacts anymore. By the time you figure how infrequently motherboards come up for sale and the cost, I think I'd do just as well with a trade in on a flat-rate repair.
But at least now we know for the record that there is another cause of dead touch screens.
well i have about 13 motherboards, if your interested let me know
Thanks. What has been your experience with changing motherboards?
The reason I ask is because the service manual wants the phone to be tuned again after a motherboard swap. I see a lot of people changing motherboards, and I can't believe that is much of a problem when you don't see anyone complaining about the phone not working well afterwards.
A spare motherboard might be a good idea for a diagnostic tool. It would have saved me a lot of work changing the touch panel and cables if I would have had a motherboard to try first.
I thought I had a good spare in a damaged phone, but when I took it out the other day to test this phone, I found out it had physical damage too. The SIM holder and RF shielding were dented, but the killer was that the daughterboard cable connector was bent.
I suppose back when the phones were $900 you might try to fix something like that, but it's hard enough to do a connector swap on a computer motherboard. I can't imagine that even the factory has the equipment to properly swap the connector even if you can get the part.
How much do you want for a motherboard? On that famous auction site I've seen them go for around $10 to $30. I could kick myself for not buying the last one I saw at $7 because I thought I had a spare.
Hello guys! Saddly for me my touchscreen stopped working but the thing is that i bought a new screen assembly but i still have the same problem and the same spot doesnt work (on the digitzer, lcd works perfectly). I really dont know what to do i have tried to google my problem but people always solve there problem by replacing the screen and i did the samething and still nothing. I'm running the latest stock rom from at&t now but i have tried to flash viper rom and cleamrom, etc... but i have gotten the same result
i tought that it could be the digitzer connector on the motherboard but it looks new so i cant find the problem...
To be more specific the spot thats shown on the image does work but when i touch it, it shows that iam using 2 fingers when iam only using 1 its really anoying when i use the keyboard. When i touch that spot, the phone starts to select things arround the "dead" spot.
My apologies if i have made some dumb mistakes in the text, i'm from belgium so english isnt my mother laguage.
IF theres no liquid damage.
The phone was working just fine, then mysteriously stopped working in one spot. I would guess replace digitizer (aka glass) But if replacing glass has yielded the same result. Now it gets tricky. Now its either a board level issue or a problem with the Kernel interfacing with its hardware.
Since not a stock device and has been rooted with custom ROM its possible those software mods might have affected it.
My suggestion is do your best to go back to completely stock and hope for the best.

Thanks but iam already on stock i have used RUU to reset the phone, same result. And liqued damage is possible any idea what would help?
Or is it possible that the connector on the board is broken?
As you start to eliminate your possibilities the fixes become more difficult.
If your back on stock everything and still bad then its going back to board level stuff. Meaning the connector on the board or something along those lines.
If thats the case then the fix is near impossible.
Might want to get a good strong magnifying glass out and see what you can find.

ok i will see what i can find, and thanks for your assistance.
Did you ever find out what it was?
My HTC One has a 1/4" section that doesn't respond to touch at all.
Hi
I have the same problem in my HTC ONE E9 PLUS where a longitudinal line along the screen does not respond. Does anybody find a solution for that please?

Most likely a faulty digitizer, replace your lcd assy.
Whenever I try to use the rear camera the display turns black while only showing the HUD. The HUD works fine, but the camera doesn't work at all. Nothing is blocking it either.
When switching camera modes (to manual mode for example), an error pops up saying that the "camera is not available"
IMPORTANT NOTE: The front facing camera is working perfectly fine.
Things I tried to do (aside from shipping it for repair):
1. Android repair via the PC companion software
2. Internal reset
3. Safe mode
4. Clearing cache files for the built-in camera app
5. Installing an alternative camera app (the built-in one was disabled)
6. downgrade and upgrade
7.change camera for new one (tested)
I had same situation with regular Z3. Someone brings it to service where I'm working and my first think was camera fault but changing camera didn't fix it. Near camera connection You can see some small capacitors, we call it filters. It looks like capacitors but it's soldered not only on opposite sides but 2 points on both sides. In regular Z3 there was 5 elements like this to change and after that camera starts working. I don't remember how exactly it's made in Z3c but it's really possible that it's the same issue and same way to fix it.
One more thing, if You can check one one more camera to exclude camera itself cause most issues like this are caused by faulty camera. I had many phones (most Z1 and Z1c) with this issue and changing camera always was the solution.
Good luck.
Same Here. Need help too.
Sent from my D5803 using XDA Free mobile app
I have three cameras and two z3c, I interchange camera and phone and always the same result
At this moment I don't have any Z3c to disassembly (except mu own but under warranty) to check where those capacitors are but if You could take a picture of camera connector on motherboard and near area I can mark which one should change.
@Chamelleon
Main camera not working
I have the same issue with my Z3 compact. The issue started happening on the 11th month of my one year warranty, I sent it for repair (14 business days y + shipping time back and forth). It came back with the same issue. Sent it back right away. After another three weeks without my phone, I got it back. Guess what? EXACT SAME ISSUE!
I called their support line explaining what happened, the guy told me that there is nothing they can do about it since my warranty expired. Of course they didn't have in consideration that I sent my phone before it expired and it took about seven weeks back and forth. There wasn't any sort of damage on my phone, was never dropped or damaged in any way, I never submerged it even if in theory, that would be ok. The report said "it has reviewed the functioning of the unit, unfortunately the defect is in the PCB so it is not able to undergo repairs to it."
The guy on the phone told me what he thought the report meant. It means there is damage on the main board(not caused by me) and the one year warranty manufacturer warranty department won't repair it. Maybe, if I had bought the 2 year "extended" warranty, they could do something about it. I asked if the issue is that my one year warranty was expired or if it is something that they just don't fix unless you get the "extended" warranty. He couldn't answer me and the only thing he said was "is there anything else I can help you with?"
From what I understood, there are two completely different departments, the one year manufacturer warranty that only cover some things. Not even sure what, because if it's broken screen, water damage or any physical abuse, they won't fix it. If it's a problem with the main board or PCB, they won't fix it either. It is a mystery to me what gets fixed in that department. The other department is the 2 year extended warranty. I'm not sure what they are willing to fix there, but from what they guy on the phone told me, it's more than the one year regular warranty.
Long story short, after two trips to FedEx, at least 8 hours total on phone calls, more than 7 weeks without my phone, I ended where I started. Sorry Sony, never again. Worst customer support I have ever experienced.
At this photo I can see only 4 of this capacitors and marked it, maybe it should be four or one I missed cause quality. Anyway regular Z3 has 5 like this and after changing all 5 camera start working again. You can desolder it from most Sony phones, I used capacitors from MK16 (Xperia Pro). So find some Sony board with capacitors like this and ask someone with good hot air solder station (if You don't have one) to change it.
Any news to this problem? I bought used Z3C with black rear camera problem because it was cheap. (Yes, the front facing camera is working perfectly fine). So far I have only tried software fixes and obviously they didn't help. I ordered new camera module from ebay and I'm now waiting for it. Has anyone tried soldering new capacitors if the new camera module doesn't help?
EDIT: Here is another thead with same problem: http://forum.xda-developers.com/z3-compact/help/rear-camera-hardware-detected-black-t3231509
As I said I've done it only in regular Z3 but If You gonna try give me some info is this solution is also working in Z3c case.

I'm still waiting for new camera module. If the new module is not working I will try soldering new capacitors. I will keep you up to date here .
Any news??
Completely forgot to post this, hope it help someone. I made the same thing with black camera on my Z3c. After I broke audio port in my Z3c and had to send it to warranty I took my gf phone, Z3c also. I restored my TWRP backup to her phone and all except camera was working. Camera was completely black but only main, front was OK. After that I was afraid that it's another hardware problem like Yours but after reflashing to stock problem gone. I repeated it few times to check if I'm right and I was. After flashing backup from another phone even without TA and Kernel backup there is a problem with camera.
So I was wrong saying it's only hardware problem. If anyone still has this issue and didn't reflashed his phone check it first.
@Chamelleon yes it's somehow a software problem (if we could say that ). For me i did fix it.
I did a Nandroid backup for my black Z3 compact (camera works properly) an restored it on my new White Z3 compact (also camera woks fine). after restoring the white z3c rear camera shows black screen, the front one is good.
=> i did a format factory reset : didn't work.
=> flashed a TFT file : didn't work.
=> flashed a D5803_23.4.A.1.232_Customized FR.ftf : IT WORKS !
and then i remembered that my phone was from "SFR" , a french network provider.
i hope this helps also
Edit: too new account, would be nice if a mod unlocks the posting of the direct image links and fixes the links - I think they are useful as this is a common problem and i already invested hours translating russian and documenting my research nobody else should have to do it
for me it was a hardware problem after dropping it.. I even changed the camera module.
Did some reseach, russian sites have some input:
Layout1: directupload.net/file/d/4472/9andayji_jpg.htm
Layout2: directupload.net/file/d/4472/vzvgbqqo_jpg.htm
It was loose, but when i tried to push it down with a hot metal to "solder" it, at some point it jumped away and was lost because it is so tiny!
Missing part: directupload.net/file/d/4472/qmut35qt_jpg.htm
The russian site suggest this soldering of bridges, however its not clear to me if they mean one of this electronic pieces (4pins each) or also the lower one.
Russian: directupload.net/file/d/4472/ag43kmda_jpg.htm
The question is now how these (likely) filters (because so close to the camera have to be bridges, it seemed to have worked for some russians:
Pins: directupload.net/file/d/4472/k86j53hr_png.htm
Not sure if there are 4 indipendend pins or if for those small footprints of electronic devices they use only the edges and then they have the same signal.
I was not able to see any text written on those two things, however i didnt have any magnifying glass.

So I changed my camera because I thought it was a hardware failure (tried every other method before: going back to stock, wiping camera files etc.) and it STILL is black. Did you have any success with your camera?

Me not (also changed the HW cam), the guys on the russian site yes (even with other similar sony).
Just check if there is something loose, maybe you are lucky and its a software problem *fingers crossed*. To me it happend exactly after dropping (and changing the screen which went without problems) so I was quite sure its HW based.

Hi basmok,
First off thanks for the research and for the pictures!
I have a similar story, phone was dropped, rear camera won't work, tried different ROMs without any luck then took phone apart and saw that one of the four tiny capacitors
just fell off and now it's MIA...
The last pic from your post (directupload.net/file/d/4472/k86j53hr_png.htm) which I assume shows the soldering of the bridge doesn't seem to work...
Do you still have that pic?
Also did you make any progress on the camera fix or gave up?
Thanks,
Ati

You were lucky, they were already in the recycle bin and deleted on the camera. Best I could do picturewise, i dont have a macro lens. Here we go, added all to imgurl so hopefully they survive longer: http://imgur.com/a/Of1DY
And no, didnt make any progress as i dont know what component they are. Normally all components have lasered some code but not sure if its just too tiny for my eyes or if they dont have it. I was a bit unlucky as i didnt have a soldering tool, so i tried it by pushing the pin down with a paperclip which i headed with a lighter --- well it jumped away and was not the best approach
Hi,
I really need your help as I have no idea what to do.
After 1 month of using MI5 Pro Ceramic black I have broke my phone,First the touch worked and there was only vertical lines on the lcd in the spot of the shatter so I could operate but due to my stupidity and of force touching the broken glass these vertical lines started to cover all the screen (Everything worked well on the phone..Sound,Camera and etc..)
So I ordered from Aliexpress LCD + Touch screen for about 70$ (Included DHL Express shipment)
When I got the screen I started to disassamble the phone.. Got everything out,Took out the broken screen and pasted the new screen on the frame (Must say all these aliexpress screens are really bad,0% protection on the screen,Not sure about the LCD quality yet but glass is horrible..Started to scratch even before I used it)
Anyways to our point..
Started to assamble back everything.. Powered on the phone and Yay! Phone is working but...
No Sound,Firstly I checked settings and everything..Ran CIT test and everything that belongs to audio giving force close..
Calibrate Speaker PA test results : State-Get impedance failed!,Speaker Vendor-None
Vibration- FAIL no short and no long
Main mic speaker Feedback,Simulation call test,Front mic speaker feedback test,Top mic speaker feedback test,
everything when I enter it giving FC with that details :
"IlegalStateException:Unable to retrieve AudioRecord pointer for SetParameters() blablala...
Headphone mic feedback test (Called on an uninitialized AudioRecord)
So in short..
No Speaker,No Mic,No headphone Mic..
Now my question is what I need to do from now.. Its not firmware/software problem for sure as before I disassambled the phone everything worked well..
My first guess was the problem is on the Sub PCB but then I asked my self..If the USB-C is working and WiFI antenna giving full signal it means the Sub PCB works so what the hell is the problem? I really hope its not something in the PCB it self as it means throw everything to garbage.. ;<
Hope to hear suggests..
I thought to order the MI5 32GB Black version take out the Main PCB put the Pro Main PCB and put also the ceramic back cover but that I would do only if I know that the problem is from the sub PCB but if Headphone mic doesnt work (Which the Main PCB take care of) then its probably in the Main PCB??
Please help!
you didnt damage the pins on the press connector? is the press connector on the ribbon cable flush / fully inserted ? Are you sure you didnt kink the ribbon cable?
I haven't pulled a mi5 apart, but can only assume its like every other phone i have.

The problem is that far as I understood of how the mi5 built and from how I saw it looks like..The Speaker located in the Sub PCB cover,Vibrate connected to subPCB,And all the SubPCB connected with the cable to the main PCB and I checked it connected good and no any damaged pins from what I was able to see..If there was damaged pins then the phone wont get charged as the USB-C wont be connected as it located in the SubPCB however it does work.. So I really have no idea what cause it..
Also the Headphone mic doesnt work in the tests..Anything related to Audio giving that FC with "AudioRecord" error..
I really must to know what causing it so I will know what to do ;<
Little update,
Just connected a bluetooth speaker,No any sound nothing..
Hi everyone! My MI5 has the same problems, no sound, mic, vibration, led buttons light, plugin earphones without notification's icon, can not play music, video offline and online video (Youtube, Facebook, live stream ..). It was happened when i replaced brooken screen. The first time when I turn on, evetything ok, I can play music through speaker, but now everything has gone..! Plz tell me how to slove this problem! Sorry for my poor E!
Hi, I ended up on buying the phone again... It's impossible to fix that problem as probably you did what I did and didn't place the motherboard correctly so a little bent probably happened and that cause to the problem.

Hi there! Care to elaborate a little more? I have also the same problem. I was replacing the rear camera module while the module I had received was broken to begin with. I hadn't really figured this out initially and I tried several times to attach it and test it, perhaps move the flex and retest, and at some I remember I found out the vibration was not there, but didn't pay attention to it as everything was open, until I found out the camera module was faulty in the end, and subsequently discovered also the whole issue with sound/vibration/key backlight etc. Instead of buying a new device, I was thinking to try and fix it, but still I'm a bit unsure about what the problem really was. From what I could figure, I didn't do anything different this particular time the audio/vibration didn't work, with respect to the previous times I attached and detached the motherboard. But is it definitely the board itself and not its flex connecting it to the sub-pcb? Could it be the sub-pcb itself or even both this and the board? In case I buy a new board (perhaps together with a sub-pcb just in case) to replace it which part should I watch out for, not to damage it again. Sorry for the many questions but you seem to be the only source of info for this specific problem.

Hi sorry for late answer,I barley visit xda these times..
After I bought the MI5 again this time in the 64gb version I tested the old 128gb motherboard (The main one) and still same problem with Vibration/Sound (While all sensors work camera too)
Which means its not the sub-pcb problem,Its the main motherboard for sure,Now what cause it?
In my opinion when I pulled of the motherboard to put it on the new screen I insert it in a bad way which made it bent a little and probably the place I bent is where the audio and all the stuff goes on..
I'm pretty sure we cant really do something about that problem as problem related to motherboard it self are usually not fixable,But if you find something I will glad to get a feedback to test on my own bad motherboard so maybe I can back to the 128gb version ;| but I doubt it..

Many thanks for the response! It sheds a little light indeed. I also ordered another phone to replace it as the cost of the motherboard seems to be equal approximately close to a new device. I'm with you, in the same view, I also once placed the motherboard quickly in the chassis without the screw that holds it together, in one of the 50 or so attempts to try and make the camera sensor I was replacing, visible to the OS, and this looseness was the unfortunate one perhaps (?). I too don't expect the sound to work again. I just wanted to double check the issue was not with the sub-pcb, which I did thanks to you. For sure I have no hopes for the mainboard to work again, but still, what keeps me from being certain it is actually the sound card that is the problem, is a very similar case I saw In a foreign forum, and also clues from my device which support the argument that the mainboard might have entered in a kind of diagnostic boot state due to a hardware fault that was apparent, where either some components are not initialized during boot, or their HW resources are taken over from the diag. ports and irqs that are enabled, in which case the issue can perhaps be fixed. For sure whenever I find a good deal on a new motherboard I will replace it, to keep it as a secondary phone, as I liked it quite a bit, but It would be interesting to see if this hypothesis holds or not. Anyway thanks again for the response!
Hi,
I've bought used mi5 with broken screen. After LCD replacement I've found that that phone has problem with sound. Exactly the same as in this thread - no sound, mic, vibration, led buttons light, plugin earphones without notification's icon, can't play music, video offline and online video (Youtube).
Someone already did LCD replacement on this phone and probably done something.
But what I discovered on this phone that problem start when battery charge aprox more then 60%.
I did flash one year old ROM via fastboot ( just to verify if it not the ROM problem) and after that everything was fine ( battery level 50%).
I did hardware test - passed 100% fine.
But when I did charge till 100% the problem come back.
That's really interesting finding... Can you tell me the same steps you did like which rom you flashed and all of that? I will check it with my dead phone maybe if I will have the same thing like you we can point on something...
mi5 lcd replaced touch not working
I bought a mi5 mobile in singapore. My display was damaged. I changed many display in india (checked in many shop). only work display (lcd). Touch not respose. please some one give solution. thank you
have same problem with op
my phone get damaged by water so im rush turn it off and open everything then go to dry it... and problem with speaker etc doesnt work just like op please help i really doesnt have money to buy new phone this month
Exactly same problem with me, just replaced the rear camera and the problem occurs
No sound, no vibration, nav led not working at all, playing video not working
Even playing sound via bluetooth speaker not working too
I believe there is something wrong with the mainboard
can anyone point out which part of the mainboard responsible for the lower board?
The lower board works well though, I tested it using other mainboard

For me the problem was that after the screen replacement (It may also apply to you after you replaced the rear camera..)
When I put back he main motherboard it wasnt sat properly,I put it beneath a small plastic holder and when I closed everything and screw and all..Problem appeared and when I rechecked motherboard I found out it got bent in the right down side and that's probably what killed all the sensors,sound and everything..
Of course that what happend to me..There is plenty of other reasons that may cause to what you experience..

I believe the chip or something similar, that control the sensor, led, vibration etc, was broken because we put it the wrong way
now we need to find which chip it is and replace it
which part of the right down? near the signal cable?

If you just checked and saw you put it wrong as I did,On the little plastic which made a little bent then I guess you lost..I would just buy new motherboard on aliexpress or just give up and buy a new phone..
As you cant really know (I mean from our side..) if its a chip related there or if its the bent it self which made problem on the connection on the board it self..
And yes I was speaking about the right side near the signal cable where you need to install the motherboard from that side where there is a little plastic like holding the motherboard..When I did the reinstall by not checking I put the motherboard on that plastic and after I closed everything and all screws got back I discovered that problem..

yeah, it means it's the same mistake as mine, that little metal thing that hold the motherboard, I forgot to eject the sim card tray and when I pull my main board it was stuck, got a little bent from there
Just wonder if anyone have the schematic for mi5 mainboard, since I'm curious and want to find a way to repair it
Not because I'm in despair of needing a phone, this MI5 is my secondary phone
Just because of the curiousity, that's all
edi--
found the schematic here
https://data.dendik.id/Data/Schematic/Xiaomi/Mi5_SM.rar
now on the journey to repair this stupid mistake, lol
any help from someone who are an expert in this thing will be really appreaciated

Yeah, tried it before, and the audio chip is gone
Perhaps something wrong with the audio chip, will try to replace the IC tomorrow
Hello,
Both the earpiece and the other speaker suddenly stopped working on my nexus 6. I am suspecting it is a hardware issue since I performed a hard reset but the issue still persists. The odd thing is that both the earpiece and the speaker are affected at the same time. Are they connected to each other?
Is there any way I can make sure that this is indeed a hardware issue before cracking open the phone?
Thanks

Hello had the same bug super user app libs was away no root from here to now did nothing.reflashed super su, without super user app like supersu or magisk it dont work for me. hope i can help.
Another question, some times i turn on my display an for 3 sec i had more than max brightness, like a sun, no auto adjust always 20%, may the old nexus now die hard, hope not
Before I opened the phone, I'd boot to safe mode and see if things work. If they do, reboot and see if the problem comes back. Booting into safe mode disables all unnecessary apps, clears caches and resets settings to default. Sometimes that resolves your problem and on reboot things are working again.

Thank you for your response. I forgot to mention I already booted to safe mode but it didn't make a difference.

So I guess it sounds like hardware. You might take s close look and see if there is damage/dirt in the jack making the device think the headphones are connected. The pin is easily bent and wears so it's probably just that. ifixit has a repair guide.
Alternatively, you might consider Bluetooth headphones [emoji4]

Thanks. I don't think it's the jack issue because I installed an app that shows a headphone icon in the status bar when a headphone is plugged in and it doesn't show it when nothing is connected.
Do you know why both speakers ceased functioning at the same time AND if there is a way for me to direct audio to only one of them, either the earpiece or the speaker, to see if one or both
are dead?
wow. I reverted back to an earlier build from Feb and now it's working. Very interesting.

First, sorry to hear about your problem. But, I am actually happy to see this up at xda. Tell you why. I purchased a uesd nexus 6 from a seller on ebay. Description was everythings works. Pics showed it was in excellent condition.
Problem was when it arrived. I discovered the top speaker was trash. Total robot like voice. Of course seller denied any knowledge of it. My option was to return it to him. But judging from the way he spoke to me. I could tell it was going to be a fight. There is no way he did not know about this. I wound up eating the phone and am currently awaiting a new top speaker. So, please dont forget to ask about speakers if buying used. My concern was body and screen. I never thought to ask about speakers and I never thought there would be crooks like him. Wrong...

It is interesting. Is it possible you had a mismatch between kernel and security updates? "Newer" kernel on "older" ROM? Or vice versa. The difference doesn't have to be more than one has a security update that the other didn't.

More like mismatched or corrupted libs or drivers
Know this is an older thread, but just figured I'd post what I found regarding a similar issue I had. My phone basically took a 3 second dunk in the sink. Everything seemed fine the first hour or two, then the speakers stopped working. However, it seems like the speakers failing is some kind of water damage failsafe or something. The solution is just to turn your phone off and on around 5 times (I can't remember the exact number, but once or twice won't cut it), and you will have the speakers return to normal. Not sure if the OP had the same issue, but just an idea in case something similar happens to others.
Bumping an old thread but I had this same issue and had to flash back to previous builds. I stopped updating my phone around Jan/Feb. Tried to update to the Aug 7.1.1 build and the same thing happened again. I didn't try the turn on and off 5+ times, I'm just once again restoring my Jan/Feb build.
Can anyone else confirm this "fix" or has this same problem?
I'd boot to safe mode first. If it works then, it has something to do with an app, your app restore process or something like that.
