I've tried all the variants of battery pulling and button comboing, but the most surefire way that has worked first time every time for me is pulling the battery, holding down volume + and -, plugging in USB, and inserting battery.
Now is it safe??

The only difference I se between what you're doing and what is typically reccommended is you are inserting the battery last instead of the usb cable.
The normal method is with battery in and power off to hold both volume buttons and insert the usb cable. I really don't see that its really that different and the only thing I would say could be unsafe is if you were to insert the battery incorrectly considering you're trying to hold buttons and whatnot while inserting it you could potentially bend one of the contacts. Other than that I would say do what works for you.

Hey guys, here's what's wrong.
I was running the latest version of MIUI and found it to be annoyingly buggy, so I installed Cyanogen from ClockworkMod and start installing it. It ended up hanging halfway through and wouldn't progress. I made what was probably a dumb decision and decided to turn it off since it seemed to have frozen.
Now...it won't turn on. If I connect a wall charger or USB cable, the symbol of an empty battery with the white loading circle comes up for about five seconds, but the circle is not rotating and the screen goes black. This repeats nonstop.
Holding down vol down + home + power to get it into Download mode fails, it just says LOW BATTERY CAN'T DOWNLOAD in red letters. Doing the same with the volume button up gets nothing. I've tried leaving it to charge for two days with no results.
I bought a USB jig and tried using it (removing battery and SIM card, putting battery back in, plugging jig in) but it does nothing. I've tried several times.
Any advice? Is it just dead?
try an external charger to charge your battery or borrow someones battery to test your phone. failing that, charge your battery in someone else's phone.
Was the battery full when you tried installing cyanogen mod, and did you follow the instructions fully?
Clean the battery contacts on both the battery and phone pins. Use another charger, and check the port for blockages/dirt (blow in it).
Try another battery..
-Leave the jig in for 30 mins.
-Hold the combo and then put the battery in whilst holding the combo.
-Plug into your computer (with battery) and try the combo. Then try without, and put battery in whilst connected and whilst holding.
-Hold combo then plug into computer
Some of the methods above may require some extreme skill or a helping hand
It could be water damage.
I don't think it is bricked as i don't think those messages would be showing up, but i could be wrong.
If none of that works and no-one else comes up with any other ideas then you may have to use the unbrickable mod. Search for it, it's a hardware hack..
Good luck
Hi, I'm facing a strange problem with my 2 years old Galaxy Note. It auto turns on as if power on switch is pressed as soon as you insert the battery. Also, if I only press the home button and volume down key together I go into download mode without even pressing power on button, similar thing when I try to enter recovery mode (I just need to press volume up + home button, without power on). So I may think of a stuck poweron button, but phone doesn't cycle in rebooting itself as it should if I pressed continuously its poweron button. Could it be the battery? Sometimes I have problems charging it... the phone stays in charge 3 seconds yes and 3 second no even if I take out the usb power cable (the icon blinks with the little thunder every 3 seconds). If I plug back and forth the usb power cable for 3 seconds twice the problem disappears... what can you say about it? Tried full recovery with stock 4.1.2 rom without success
This may or may not be a power button problem. I had this problem myself! Try removing your battery, cleaning carefully your micro usb port with a thin toothpick and try gently moving it up or down but really carefully!!!, insert your battery and try again. I had problems 2 3 days after cleaning it, but after that no more problems. Also see if your battery has a little bulge. If yes, then you should replace that too.
Hello. This morning I've turned off the alarm, turned on WIFI and went back to sleep. I can't tell for sure, but I think the battery was low. During the next 2 hours I checked the time several times. I don't remember accepting any OTA. Eventually I got up, tried to check the time and the phone was off. I tried to turn it on, no effect. No matter how many times and for how long I pressed and held the power button, the green LED only flashed for a split second and that's all. I plugged in the charger, and the LED stayed lit -but- there was this barely noticeable flickering. Charged it for about 30, 60, 120 minutes, didn't start plugged or unplugged. I went to work, 8 hours later (phone was unplugged) I tried to turn it on again, this time the LED doesn't even flash, but when charging there is no flickering. No combination of buttons works. Windows doesn't find the device, neither does RSD.
I've never done anything 'custom' to the phone. The last change I made was setting the alarm to turn off by shaking (yesterday, never used this option before).
Is it dead?
Try taking SD card out and holding Vol down and then Power for 20 secs, then let go of Power,
Already done that, nothing. No matter how long I charge it now, after unplugging and pressing power button the LED doesn't even flash. Could it be a battery problem (before its death, it would last for a day)? Is there any way of recovering my data without buying a new one?
Try opening and disconnect battery for a bit.
I'll do that as a last resort, on weekend maybe since I don't have the tools with me. Any other clues?
Nobody knows how to help me?
I'm going to make a factory cable. Will this alone allow me to recover the data? Or if I'll be able to flash the phone, can I recover the data afterwards?
Also, I'm not sure if I understand correctly: does the factory cable recharge the battery or not? Is there a way to recharge it when removed from the phone?
Try to use medfield unbrick script. If You have only green led it seems to be bootloader error so this script should bring Your phone to life or Your phone has broken emmc and You can start looking for a new logic board. Good luck.
I've installed the drivers, but Windows and XFSTK don't recognize my device at all. Factory cable also didn't help. I liked my phone very much. :angel:
Did You enter medfield mode using combination with camera button??
By a combination you mean holding the camera button and connecting the phone to a pc? I tried that.
Disassembe Your phone, pull out battery, push power button for a 10 sec, plug in battery, push camera button and connect USB. If it wont help You I don't see any hope for Your phone.
Well, new option to try is a new hope. I'll try that on the weekend. Could you please be more specific:
1. Pull out the battery.
2. Press the power button and wait 10 seconds.
3. Insert the battery: should I be still holding the power button at this moment?
4. Press the camera button.
5. Plug in the usb cable (factory? regular?) - should I be still holding the power and camera buttons?
Battery trick is only to discharge capacitors. Sometimes even phone is dead it can turn on in some strange mode and then You can't boot it to flash. Thats why You need to pull out battery, push power for a few sec to completely discharge motherboard and just release this button. After that You can just plug in battery and continue normal unbrick process - so hold camera button only and connect regular usb cable.
You can also try reset option instead of pulling battery out. To do that do not disassemble Your phone but just plug in regular USB, when phone starts (green led) hold power and vol- until green led goes off and then quickly start holding only camera button.
I have no more ideas.
Ok, I've tried everything. Nothing brought my phone back to life.
Thanks for all your help.
So I think I did something which I've not done before - brick my phone completely.
I got two Z3C so this is my 'spare' one which I was testing CarbonROM on. Because I want to ease my transition to a new ROM I wanted to backup my entire "main phone" and restore it on my secondary phone, with TWRP. When I tried this, it seemed like it only wanted to restore system, data (excl storage) and something else I can't remember. But it didnt include the FOTAKernel and stuff I had taken a backup of from the other phone.
Anyway, the restore failed when it came to data (excl). I gave the phone a reboot and since then it's just been flashing a red light. I can't hold down power button and vol down to simulate the battery pull. If I plug in USB while holding volup or down it doesnt enter flashmode or fastboot - it just blinks red.
The phone was plenty charged when I worked with it, 50%+ was the last battery level TWRP told me.
Other googlings bring me to people who write its a hardware fault - dead motherboard or so. Others have experienced it with waterdamage and stuff like that but my scenario is nothing like this.
Any clues ?

I don't think you can restore from a different phone. That's probably the cause. However, I also have not heard of a hard-brick happening just by trying to flash the wrong thing in TWRP, (but maybe possible).
I have had the red light issue a few times, after flashing bad zip, but not on Z3c, on my XA, and I was able to resurrect it by holding down volume and power buttons while plugging it in, but for some reason, it only worked when I used a different charger/cable. All of a sudden it pops back to life with zero battery, (it was full when it died). Maybe you can try that.
I've also found that with some custom rooms / kernels, you need to hold volume and power buttons for about 10 seconds to get it to respond...

Hm. I've had it charging from USB connected to my laptop overnight - nothing different. Plugged it into a real charger when I went to work, will see when I get home.
It doesn't react to the powerbutton + voldown combo, which I've used extensively in the past. I haven't tried plugging it while holding any button. Did you plug it into a charger or computer USB port?

I did the same thing for a whole day, (tried to leave it plugged in to charge), and no response, but when I changed the cable and power source, and held down the buttons while plugging it in, after a few tries with different buttons, it suddenly popped on, with zero battery, and started charging.
Also, you might try posting in a TWRP thread. See if anyone has seen this before...
Poco M3 Pro 5g
Stock rom
Locked bootloader
It was powered off for some time because I had to replace broken display
Now when I try to boot a battery icon appears and then it turns off. Same thing happen when I plug in the charger
I repair smartphones professionally so I am sure no hardware damage during the repair

I went through it. try holding the power button, connect the cable and only release after the battery shows 1%. you can try holding the power and volume + or power and volume - buttons too instead of Power button only, in the same way. alternatively, you can leave it on the charger for hours and it might turn on. Make sure you are using the supplied xiaomi charger
If I plug the cable or I plug and hold the power button the phone just tries to boot continuously showing the battery icon and then turning off and repeat, nothing really happens
Is that what is supposed to happen?

Yes, It happens. Luckily the phone will reach 1% and charge normally, keep trying
You actually saved me, it worked in the end, after some loops it booted alone, all I had to do was just let it sit there, didn't even have to keep power button all the time, once it started the loop I just left it there and when I came back it was booted.
