I am looking for help for my phone - has anyone had this kind of problem before and solved it?
As per the title - I cannot start my phone any more, I do see the yellow Pocophone logo and "unlocked" status - then the screen goes black and the phone seemingly does nothing any more. Trying to get into recovery does the same, however I am able to get into Fastboot mode.
What did i do - nothing Was using my phone while on the bus, put it into my pocket where it must have turned off, when trying to switch it back on I noticed the behaviour above. I was on TWRP 3.3..0.0 and the Pixel Experience ROM (Android 10) when the phone failed.
ADB on my computer does not recognize the phone, but MiFlash does see the phone. I tried to flash the current stock MIUI - with "success" from MiFlash but no effect on boot behaviour.
The charging led is off when connected to charger or computer.
I am a bit stuck with other things i could try- does anyone out there have an idea? Oh - and the additional bit - this is my own import from China to Europe, from a bit more than a year ago (January...) so I am out of any warranty thing.
Cheers

Hi guys. So I have been going through xda and Google for hours and hours trying solutions, to no avail. I almost never post on forums for help because I can usually find the solution. Not this time. This is my last resort next to throwing my phone out a window or praying for death's sweet release.
The facts: I have a rooted Xperia Z3v. I tried to upgrade TWRP in order to follow some directions on upgrading to Nougat. I flashed TWRP from 2.8.X.X to 3.X.X.X. I rebooted and it never made it to the Sony logo. Now, if I plug the phone in to either a wall socket or PC it vibrates, endlessly at three second intervals, each time with red LED. If I try to enter flash mode, then its the same but with a brief green led after the red. I can enter fastboot (the only way to stop it vibrating while plugged in) and my PC sees it, including Flashtool, but since my bootloader is locked permanently, I can't really do much with it.
When plugged into the wall-charger, I noticed that the charger's LED changes from "Active" to "Inactive" with every vibration. I'm pretty sure I'm in a reboot loop. The screen is totally dead and there's no logo, but every three seconds it kills it self and comes back.
I have tried everything I could think of.
What I have:
I have the stock firmware ready to go
I have TWRP backups on SD card and PC
I have Flashtool
I think my drivers are good, but not 100% sure
I can fastboot
I'm at my wit's end and losing hope.
Please, I'm open to any suggestions at all.
hello guys, i already put two or three new thread on miui forums about this, no respond since.
i bought this device from someone,the device can't be turn on but the screen will appear MI logo when connects to charger (or computer). the battery seems not charging so I cant access to recovery mode, no fastboot mode... only MI logo and red light blinking all the way.
So i manage to force edl (emergency download mode) from test point at its motherboard for flashing purpose as the device is locked bootloader, successfully flash without any problem but still... no luck. :crying:
I suspect the battery, not suspect any other because motherboard and usb sub board seems to be working fine, or else the flashing wouldn't be success in the first place.
so any suspicious? or tricks that I should do before replace the battery...?

It look's like battery problem, but not sure.
Just replace the battery
Replace your battery.
Got this Xiaomi from gearbest with miui 8.2, y unlock bootloader, install twrp and flash to miui 8.5 stable. Everything was fine, almost a week since i flash, install apps, wifi, calls, youtube, charge everything seems ok. But today he was no showing me nothing on screen, black, sounds and the system to be fine because i can hear when i touch icons or setting etc. I restart and turn off nothing, one time show me logo mui but just once. I try to enter bootloader menu and twrp as well and black screen still present. On the fastboot cmd menu it appears, but no screen, even i turn off and charge to see if the battery shows and nothing, it charge but not shows the icon.
Is a problem of factory or software (flash twrp)?

If software was the cause, it will be easily fix after resetting/clean flashing.
Since the phone still detecting from PC, use this to format/clean flash your device through fastboot and see if it fix.
On the other hand, those problems you've indicated seems to be a serious hardware issue (LCD/Display related one). Still got that warranty? ye? You could bring the phone to nearest xiaomi service centre and have it checked.
Helloooo,
I have a big problem, cant get my phone running again.
The sad thing is, I just got it 4 hours ago
So heres what I have done to my Phone:
I rooted it with Kingo-Root and then installed a app where TWRP was listed, there also was CWM and stuff and I thought I have to flash my phone there with TWRP to install a new ROM and stuff and I clicked there on flash.
Then it asked me if I want to restart in, I cant remember recovery and/or download mode, I clicked yes and from there the trouble began.
When it starts the Coolpad Logo appears, then it say "Download and install the package?", to confirm volume up, to abort volume down. If I press abort, it just goes off, the restart may leads to the battery charging screen ( usb cable is always connected!!), if I press volume up, it says "Information - Do not disconnect data cable", but it says it for forever, nothing happens.
If data cable isnt connected, it shows Logo and then goes off, doesnt do anything.
I wish I would have never done that, Im too stupid for stuff like that.
Can someone help me out?
Hopefully
Hi are you able to enter in TWRP recovery in orden to try to flash him back to stock rom ?
Sadly no
I read some stuff on the internet, and tried it:
I installed andoid studio on my PC, with all that drivers, connected the Phone to my PC and looked it up in the device manager.
Before it was just recognized as "Other devices - Android" without any information, now I had the Hardware ID and put that into the setup text of Google drivers and installed them.
My PC somekind recognizes the phone. (but not like normally)
Maybe i can get the Stock Rom to phone that way somehow?
Edit: its called adb interface in device manager
Now I tried to set up the stock-rom via YGDP, and well, it kinda worked.
Im now out of this mode.
If I start the phone it makes its starting sound and it response to "key"-presses by vibrating, but, no screen, its just pitch black.
Its not listed in device-manager anymore.
Any suggestions?
bad support.

That is probably because you flash incompatible firmware which does not recognize display of your device .
Search on the internet for another genuine rom and repeat flashing process .
I had alsmost same issue when I flashed Blu Studio D572i with rom of D572a as I remember , was black screan completely but buttons are working (showing light) .
Hello,
some days ago I noticed that my Poco F1 (with Lineage OS) is draining battery from 60% in the morning to 15% in the afternoon without using it. After unlocking it from lock screen it told me that it would like to stopp some apps from eating up battery. I agreed.
Some time later I grabbed my phone again and now I was not able to log in. The screen stayed black although my mobile was running.
I switched it off with power button and on again but I could not pass the Poco F1 boot screen. Fastboot Mode was possible too. TWRP was somehow gone. I was not able to enter TWRP. So I entered FasBoot and flashed TWRP (same version as before) again. Still not possible to enter TWRP. So I flashed Orange Fox. But it was not possible to enter that too.
So I flashed the phone completely with the automated Xiaomi Poco F1 repairtool back to the original Global ROM. The bootlogo change to a different Poco F1 bootlogo with the android sign on bottom and now the unlock sign was on top but still no chance to pass the bootscreen. Still no TWRP / or other Bootloader. Only Fastboot or Bootlogo.
What else could I try? I have opend it and removed the power cables so that it will not drain my battery cuz I could not switch my Poco off. (
Is it really bricked?

I think the problem is that since I flashed a new global system I do not have USB Debugging enabled. (?)
But there are other problems too:
I can only enter "fastboot" mode. No bootlader (No TWRP/No Orangefox/No Miui Bootloader)
The only screen I get is "Poco F1" Bootlogo.
No errors are reported back. The files seem all to flash fine. But still it won't boot. Just "Poco F1" bootscreen. (Bootloader still open though.)
:sigh:
Thanks anyway.
