[Xiaomi Mi 5 Questions & Answers] edoroom:
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.
[Xiaomi Mi 5 Questions & Answers] edoroom:
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..
[Xiaomi Mi 5 Questions & Answers] minhanh_tran:
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!
[Xiaomi Mi 5 Questions & Answers] edoroom:
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.
[Xiaomi Mi 5 Questions & Answers] deusxx:
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.
[Xiaomi Mi 5 Questions & Answers] edoroom:
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..
[Xiaomi Mi 5 Questions & Answers] deusxx:
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!
[Xiaomi Mi 5 Questions & Answers] alexwood2000:
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.
[Xiaomi Mi 5 Questions & Answers] edoroom:
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...

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
[Xiaomi Mi 5 Questions & Answers] codearm2:
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
[Xiaomi Mi 5 Questions & Answers] edoroom:
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..
[Xiaomi Mi 5 Questions & Answers] codearm2:
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?
[Xiaomi Mi 5 Questions & Answers] edoroom:
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..
[Xiaomi Mi 5 Questions & Answers] codearm2:
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
[Xiaomi Mi 5 Questions & Answers] feel2death:
ok bruh im already do some fking around and do ic audio replacement but no hope its still broke even my repair guy who are ex xiaomi worker are give up the problem is looks like from cpu its self but there was something interesting if u try download device info hw app in google play there was warning that the device cant read sys or something cuz it was blocked and when u look at audio chipset its was gone
[Xiaomi Mi 5 Questions & Answers] codearm2:
Yeah, tried it before, and the audio chip is gone

Perhaps something wrong with the audio chip, will try to replace the IC tomorrow
[Xiaomi Mi 5 Questions & Answers] feel2death:
im already try it change the ic audio its still not works its seems got cut off connection between audio and cpu
[Xiaomi Mi 5 Questions & Answers] codearm2:
I've talked with some people at Xiaomi (engineers, those who are responsible for the hardware, etc) and yes, it's the SOC problem and it will need a lot of effort to fix it, also it doesn't worth fixed they said

better to replace the mainboard

so for anyone, who stumbled upon this thread while searching for solution, you guys now know the answer

Hello All,

On my MI8 Lite, I got only have a buzzing sound after screen replacement.

Do you have any tweaks ?

Thanks
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] avicohh:
Hi Evryone.

Because I didn't found CWM or TWRP Recovery or any root method for the galaxy J5 J5108 and the J7 J7108, I made a pre-rooted firmwares for those models.

This firmware base on the hong kong firmware which include the Google apps, this a full firmware exactly like the original, except the root.

After flash you will see the SuperSU app in the app drawer.

Also, this firmware contains the bootloader from the china firmware which doesn't have frp lock.

The root include the binary files in the system, and a pathed boot. (from Android 6.0 or samsung 5.1.1 pathing the boot is necessary for the root work properly)

Flashing this firmware will not wipe data automaticly. you should not lose anything.

This file will work on any firmware/baseband/csc. you can always flash it like a stock firmware.

J5 - base on - J5108ZHU1APD2.

Android version: 5.1.1

J7 - base on - J7108ZHU1APD1.

Android version: 5.1.1

J7

Installation instructions

Before flashing check the CROM Service status in Download mode, if it locked you will need to unlock the bootloader first with the app attached.

Install samsung usb drivers from here.

Download the self extracting 7z file above and extract it (just double tap) to some folder, you should receive a tar.md5 file.

Open odin 3 (attached in the zip)

Put the tar.md5 file in AP.

Put the device in download mode. (vol down + home + power button, and then click on vol up)

Connect your phone to usb and wait for odin detect the device.

Click start.

After it finish choose reboot system now in recovery.

Enjoy.

[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] billeuze:
Thanks a lot avicohh. This was simple and painless. I now have google services on my mainland China phone. And root too! And like you said - I did not loose anything.
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] billeuze:
well now i am stuck. I enabled my google account, installed and updated my apps through google play, shutdown and now I can't boot. The message in red on the top of the boot screen is:

"KERNEL IS NOT SEANDROID ENFORCING

Custom Binary blocked by FRP lock."

I also cannot reflash the same HK rooted firmware using Odin

apparently I should have enabled developer options then enabled OEM unlocking before rebooting. But I didn't know that so for now I am bricked

Also apparently, the fix for it is to reflash the original firmware using Odin. I am now downloading the firmware from http://updato.com/firmware-archive-select-model?record=1F170CA05E5611E6B055FA163EE8F90B but it is still another 2-3 hours to complete the download (yes, poor internet connection here.)... So I'll see how that goes...
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] billeuze:
OK, that didn't work. Now the message on the download mode screen says:

SW REV. Invalid type.

FRP is enabled, not allow download non FRP bootloader binary
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] avicohh:
Well..

I just recently had the same problem in another device.

I don't think the "Oem unlock" has nothing to do with this. the problem is that when you're adding Google account the frp (factroy reset protection) is automaticly enabled, and then it blocks the pathed boot.

The reason reflash the original firmware didn't work for you is because you tried to flash the china version, that doesn't have google service and also doesn't have frp in the bootloader. (apparently once frp is enabled this kind of operation is not allowed because you are actually trying to remove the frp lock by flashing bootloader..)

I think the solution will be to flash the original hong kong firmware with the frp bootloader and original boot. (or just the original boot)

http://updato.com/firmware-archive-select-model?record=5C13445B54D811E6B055FA163EE8F90B

Then, try to enable the "Oem unlock" option and finally flash the rooted firmware again.

maybe it will work, I'm not sure about it but I would like to know.

If this won't work, I'll try to combine the rooted hong kong firmware with the non-frp bootloader from the china firmware.
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] billeuze:
Thanks so much for replying avicohh

This makes sense. I was actually suspecting this and was considering trying the 6.01 HK version since that is the only one I could find: http://updato.com/firmware-archive-select-model?record=5C13445B54D811E6B055FA163EE8F90B

Now that you've posted a link to your original 5.1 HK firmware I'll try what you suggest. I'll wait to get home before I start the download.

But I still wonder if the 6.01 would work on my phone?
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] avicohh:
It's a mistake.

This link above is 5.1.1, not 6.0.1.

There is no 6.0.1 fro this model for now.
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] billeuze:
yes, I see, the website says its 6.01, but its actually 5.1.1. How do I know? BECAUSE IT WORKED!!! It took 7 hours to download but when I got up this morning it was done, I flashed and it worked!!!

I'm going to read up some more on this FRP business before flashing the rooted version again. My old phone (very old) had no such thing. I'd never heard of it till this unpleasant way of learning about it.

Hi guys.

Thanks for your replies.

I've just checked it now on another device.

As it turn out after a several tests, this "custom binary blocked by frp lock" problem occurs only if the oem unlock option is disabled.

Here is what I did, step by step:

First, I enabled the oem unlock option and then I added Google account - nothing happened. frp lock in Download mode is still off and everything working fine.

I removed the google account, turned off the oem unlock option and finally added the google account again - frp lock in download mode immediately switch to on, and when I tried to restart, the device has stuck on the boot. (custom binary..)

I flashed stock firmware (from the link above), the device now bootup normally but the frp lock in download mode is still on. (I didn't remove the google account yet)

Final check - I enabled the oem unlock again, and the frp lock in download mode switch to off.

So..

I can safely say that all you need to do is just enable oem unlock in developer options, and then flash the rooted firmware.

Anyway, to be even more sure, I made a new firmware with the china bootloader, frp now is not even exist in download mode.

You can download the new firmware from here

Good luck!

Hey, How do I enable OEM unlock when I can't even boot my device. it simply refuses to boot.
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] avicohh:
Hi

First flash the original HK firmware from here. the device should boot up normally.

http://updato.com/firmware-archive-select-model?record=5C13445B54D811E6B055FA163EE8F90B

Then, enable oem unlock.
[Samsung Galaxy J7 ROMs, Kernels, Recoveries, & Oth] billeuze:
Thanks for making the root version of mainland firmware. I'm going to stick with the HK version as I want to have google services. and thanks for testing the oem unlock

I informed myself some more about FRP and OEM unlock and I am now feel safe to use the rooted HK firmware. Except, I came across one note for which I want further clarification before proceeding. The note is from http://www.androidcentral.com/factory-reset-protection-what-you-need-know and it says:

"A couple notes need added here. This doesn't undo Samsung's (or anyone else's) version of Reactivation Lock. If you've enabled data reset protection through your Samsung account, you'll need to turn that off in your Security settings. You can find the switch under the "Find My Mobile" section."

So, I want to be sure I don't have this samsung Reactivation Lock enabled. and that I am in no danger of it auto-enabling. I believe I am safe but I would like to know if anyone has more clear information.

What I do know is before I flashed to HK ROM, when I went into download mode, there displayed a setting:

"REACTIVATION LOCK: OFF"

now, using the HK ROM, it is gone, but in that exact same location is the setting:

"FRP LOCK: OFF"

I think, that means the mainland version of the FRP lock (Samsung Reactivation Lock), is now replaced with the google FRP lock and as I don't have to worry about the samsung reactivation lock anymore. Is that so?

even so, as the article says, I look in "Settings" >> "Lock screen and security" >> "Find my mobile" >> log into Samsung Account when prompted, then it does not display the "Reactivation Lock" option that is shown in at least one guide that I found. I really think this is further proof I don't have to worry about Samsung Reactivation Lock. Can anyone confirm?
