I have had a M-G900F running CM for some time. The hardware seems pretty tough. Accidentally dropped it about 5' onto a hard tile floor and it turned off. No big deal I thought, screen still intact, just put the back on and reboot it. Nothing. Nothing whatsoever. Symptoms:
When pressing power button, phone vibrates as if turning on but nothing happens, it does start to get warm though
No sounds or other indication that it's just the screen disconnected
No lights while plugged into charge
Can't get into download mode or recovery mode
Tried multiple other batteries, no difference
When plugged into WIndows PC, recognised as Android device and drivers automatically installed
Other than that, zero signs of life whatsoever
Is it gone forever? Which hardware part is likely to be at fault?
I'm not too bothered about the phone itself but I do want the data on it. Without being able to power it on, is there any way at all to get data off the phone? USB jig?

All the evidence points to it not being a dead screen. Otherwise it would make boot noises etc.
if the screen doesnt do anything nor the light on the front but it vibrates, its likely the screen is dead or the ribbon cable going from the GPU to the panel went bad, but i dont think its bricked. There are cables that will show the phones display on a tv or monitor via hdmi that could prove or disprove my theory, but its pointless. A replacement screen will likely fix it, but the cost to do so would make me balk at that option

thats all well and good, but it could also be part of the mobo having died with the screen. Not sure. But if it vibrates when the power button is pressed, its obviously doing something.... anyways, i think its a paperweight at this point

I hope you're right that it's just a dead screen. My instinct says it's something more serious. Is it worth stripping it apart myself and trying to reattach the ribbon cable? Or perhaps I could buy a screen off ebay, attach it long enouhh to recover files then sell it on again?

Looks like a hardware issue, and to fix that you'll probably need to change the physical button.
To power the phone on, just connect it to the charger, it will start.
I too have the same problem, just started around this thread's start date too.
Oh yeah, and connecting it to the charger doesn't work, and the only way I can get any life out of it is to pop the battery out, put it back in, but even then it only goes to the "SAMSUNG" logo screen and then blacks out again.
I feel like it may be the power button itself, because I managed to turn it on when I pressed the button fairly hard, so maybe the button is pressed in and stuck to some extent?

In your case it's definitely the physical button and you'll need to change it. Maybe there are some video tutorials on how to clean/change it, check it out.

Then it's not the hw button itself, I stand corrected. Looks more like a soft/firmware issue, considering the power adapter doesn't power up the phone.

i agree this idea. you can have a try. if you can't get success, maybe you can
demount it...
So first some back-story, I'll get right into it. I recently dropped my phone in some water. As soon as possible I dried off the outside, and let it sit. That was the only thing I could do at the time, I had no rice, no tools to open up the phone, anything. I ended up with a solid red light, and everything unresponsive.
The next day I got some tools to open her up. There was pretty extensive corrosion to the motherboard, so using some alcohol I cleaned it all off, rinsed it, and let it dry. I also took apart everything else and cleaned any corrosion. The inside looks brand new. However, this isn't the point of the thread.
It appeared my cleaning helped quite a bit. Upon re-assembling and plugging in, I immediately got a charging sign on the phone. However, after trying to power on, I got no response. Additionally, The charging signal went out after about 20 seconds, and the whole phone became unresponsive again. I can do this process as many times as I want, but the same thing happens every time.
So I tried a different approach. First I hold down both volume rockers plus the power button, and plug it in while holding them down. This puts the phone into "download mode" However, once in download mode the phone is, again, unresponsive. After plugging into my laptop, my computer recognizes the phone, but not as "Nexus 4," but as "Full JellyBean on Mako."
Is there anything I can do about this? I've heard about drivers being able to be installed when in download mode, but I would not know what these are, where to get them, or how to install them. I really don't mind if my phone never works 100% again, I doubt it would. I just want to be able to get into the storage so I can recover some of the files I lost.
It's also probably worth mentioning I have not gotten a solid red light after the clean. Once in a while I will get a blinking red light after plugging it in, but after less than a minute it stops and goes through the charging/stop charging phase I'm so familiar with. Any help at all would be appreciated, and thanks in advance.
The charging block and/or battery could be wrecked, for safety reasons and because it will probably become faulty soon you should change the battery anyway. If the charging block is broken flashing your phone could fail. It's also possible the board was irreparably damaged, but it's probably worth a try as the parts aren't too expensive.

After trying to figure more things out, I kept it plugged in for a while. It appears my battery actually holds at least a pretty good charge, as the indicator is full when I plug it in now. However, I don't know what you mean when you say charging block.
Also, I seemed to determine my power button isn't working either. I always thought no response to pushing it meant there was something else going on, but I am able to put it into "download mode" by just holding down the volume rockers and plugging it in. Is there a way to turn on the phone another way besides the power button? Also if not, will buying another power button fix the problem? I don't want to buy one then later figure out the reason it wasn't turning on was just a board problem, and not a problem with the button itself.
You can short the power button with a screwdriver or something should turn the phone on., By charging block I mean the secondary board that the micro usb port is a part of, it can be replaced fairly easily if necessary.

With a screwdriver? Enlighten me, I'd have no idea how to do that. If I had a faulty charging block, then my phone wouldn't be able to charge correct? My phone was plugged in for a while in download mode, and it gained a full charge from a relatively low charge. I also took the block apart and cleaned any corrosion, so I think that's still functional.
Some more progress, upon further attempting to turn the phone on, I was able to get it into fastboot mode. When plugging into the computer it is recognized, but as just "Android." I will type out what information is displayed here, minus serial number, as a new member cannot submit links in posts apparently.
FASTBOOT MODE
PRODUCT_NAME - mako
VARIENT - mako 8GB
HW VERSION - rev_11
BOOTLOADER VERSION - MAK0230d
BASEBAND VERSION - M9615A-CEFWMAZM-2.0.1700.98
CARRIER INFO - None
SERIAL NUMBER -
SIGNING - production
SECURE BOOT - enabled
LOCK STATE - locked
Also, fastboot at the top (as far as I know) usually says "Start" or "Recovery Mode," but mine says "Restart bootloader." When I try switching with my volume buttons, nothing happens.
Another update, just in case anyone is still listening..

Now that you're at this point, have you attempted to flash the phone with a stock image? I'd be weary of what the other poster said though and ensure your USB connection is holding steady because you don't want it dying half way through a flash because then you'll have a brick.

I have tried actually. I used the Nexus Root Toolkit v1.8.0 to try and flash it. At first it wouldn't find the device, but through device manager I manually installed the usb_driver onto the phone. After this, the toolkit was able to find the phone. I attempted to flash the image, but it ended up staying in fastboot mode. The program then suggested I try to enable "force flash," which I did, and this time it was never able to finish because the phone tried to restart, but went through that "charging to unresponsive" state I described in my first post.
Upon trying to flash it normally again, it looks like maybe the phone has to be unlocked to do this properly? I then tried to unlock with the same program, but in order to do that, I need the power button to confirm I actually want to unlock the phone. So yet again, I need that power button working.
Any ideas/suggestions/solutions would be amazing.
Jellybean on mako means that your phone is in lgnpst/qcpnst mode. Looks like something failed to start and made the bootloader trogger that mode

Got the same problem right now, trying to solve it. Was about to post new topic but saw yours. Can you boot your device into bootloader? Mine seems to be able to do that and I see everything but once it shows the Google logo during normal boot or recovery, the screen goes dark and blank.
Very mysterious indeed, never seen this issue before...
Hoping someone can shed some light on this...

Can you remind me of how you did it?
Cause vol up+power\vol down+power won't work for me
What screen have you bought?
Cause I was super anxious about getting original Hydis, now chungwa they now sell everywhere
at first, I would think that I somehow messed uo the cable - but if you are saying, that you are able to boot

Vol down + power. Though upon further reassembly, it seemed to get worse. Now my screen won't even light up or show anything. Try shining a flashlight on the LCD panel. Do you see anything? If you do, it's likely a bad data cable. In which case, you should find one on eBay.

It isn't working at all(
But I can't be 100% sure, cause I've so many change cycles
Buying things on ebay means +1 month of waiting, so I'd prefer to know exactly, will the new cable heal me tablet
Anyway, have you decided, what happened to your screen?

For me since I shone a light and there is something showing underneath and I know that the panel should work since I did see a Google logo and fastboot did properly show up before I reassembled it again 2 times before it completely disappeared, It's likely the data cable, so I repurchased a data cable from eBay.
Have you tried shining a light on to the LCD panel to see if you see anything? If not, it's likely a faulty LCD panel.

no life at all. even when its connected to my pc. if i plug the charger in it just gets hot.....thats it.
can i assume its bricked for some odd reason??

no responce and all. if i plug in the charger the top half of the phone gets quite hot in the main board area.
im sure some people come on hear with problems with out telling the full storey ( dropping it down the toilet,or just dropping it) but i literally shut it down to charge it quicker.
im still scratching my head over this.
if all else fails i may look into buying one with a smashed screen on ebay and replace the main board as my phone is in great condition,....gutted.
it does sound like a hardware issue - can you take it back to a samsung service center?

If you tried another working battery, tried connecting to a computer and cant get into Download Mode.... I say your phone is dead and it sounds like a hardware fault. I have seen soft bricked and hard bricked phones, they still show some form of life like the led turning on, pixel salad, black screen (as you can see the screen light up), white screen, cant get into recovery but can get into Download mode and etc.
Sounds like its dead but I am sure its got nothing to do with what you did and its just a coincident that it died.

Hello folks.
So I left my A1 charging at night, the alarm woke me up as usual in the morning. Just before leaving home I took it to check the time and then it was already "dead".
PS: The phone was never been knocked over, wet etc...
Symptoms:
- Black screen, as if was turned off / without battery;
- Buttons do not work;
- Doesn't react to any connections.
- Doesn't enters fastboot mod;
- It's not recognized by the computer;
- Also not charging.
Any help is welcome, best regards.

It's a possibility, but it's strange the phone has like 4 months of use, never had any problem.
I'm willing to try some stuff first, even open the phone to unplug and replug the battery on the mb.
Otherwise at my country (Brazil) Xiaomi has no warranty

So yesterday a oppened the phone, disatached the flats and atatched then again, unfortunatelly didn't help =[.
We also made some tests and seems like it could be an issue with the battery seems like it's not charging nor receiving any charge.
Seems like the "regulator" of the battery or something like that is not working as it should.
I'm gonna try to test this a in a more acurate way, at least to be sure that it's the battery.
Probably on EDL mode. Try reflashing stock with MiFlash. Helped me once.

The phone will power on without any battery attached at all, so remove it and see if you get life. If not, then it's not the battery.

You can try make edl usb cable first, if not work then search mi a1 test point, you'll need to jump 2 point on motherboard with wire/pin.

So yesterday i tryed to make the phone enter at the EDL mode, by jumping the 2 points on the motherboard. Unfortunately the computer didn't recognized the phone at all, i'v tryed several times.
I'm starting to think that something related to the the motherboard just died.
I'll lend it to a tecnical that can fix it or at least confirm the death of the phone to me.

Just tested it yesterday, without success.
Even with the battery disconnected and ubs at computer or charger, the phone still not giving any signal of life.
Does it mean that it must be a serious problem?

Hello mate.
I'm sry for you phone, at my case i'm starting to believe that the mb/cpu died.
I was thinking that it could be the board at the bottom (ubs, mic jac) but i have been told that it's really rare this to happen.
Yesterday i tested the battery and it's fully charged, (so the battery isn't the problem)
I'm weeling to take it at the end of the week into a tec who can test all the hardware stuff in order to know what actually have failed.
Have u also tryed to engage ur phone at EDL Mode?

Hi.
Yep also tried shorting the test points, it does not respond to anything. Just totally dead.
Its sad cause i really loved that phone. I might buy a used cheap one with a broken screen and use its main board or other parts.
Thanks Knievel
