My friend left his phone overnight on the charger and when he woke up his phone was dead (he said he wasn't updating phone and autoupdate was off), device is nonresponsive and only thing that shows up is flashing notification light when it's plugged and screen doesn't lit up at all (can't boot in fastboot mode).
But when i disconnect the battery and plug in charger, it shows redmi logo and empty battery logo, I can boot in edl mode over test points and my pc detect the phone only in edl mode.
When i try to flash system image it gives me the error "Your account is unauthorized for this operation", but when i signed in earlier it showed me "Your computer is bound to your account, you can start now".
I don't know if motherboard is completly functional so I don't want to spend my friend's money to pay for authorized account if I'm not sure that will solve the problem. Any idea how to fix this, here is mi flash log:
authentication failed Cannot create a file when that file already exists

at XiaoMiFlash.code.bl.SerialPortDevice.ConfigureDDR(Int32 intSectorSize, Int32 buffer_sectors, String ddrType, Int32 m_iSkipStorageInit)

P.S. Sorry for bad English.
This happens a lot with these phones. Heard it happening to two others. A factory reset might revive it if you're able to access the recovery? I'm guessing you can't though, I have a friend in a similar situation, will be interesting if anyone else has managed to resolve their issue like this.

Hi, I got Motorola Moto G, original system, no root. I just encrypted my phone, process most probably finished without problems - I stopped watching the phone on around 90%. Then it restarted, boot animation, "enter your password to decrypt the phone", I type it in, green robo shows for 1 second and then black screen (backlighted) :/ After couple hours nothing changes.
If I type wrong password, phone ofc doesn't acccept it. Computer sees device, but I can't access it. When I turn off the phone by pressing POWER for long time, it just resets and goes back to asking for passwod again.
Please help me recover my data...
EDIT
before entering password PC says phone is off, after typing it, PC says it doesn't have drivers (it worked normally before encryption).
EDIT 2
I can enter fast boot, but IDK what next. Recovery mode just ends with "NO COMMAND"
I see that probably all users who got this problem have Motorola Moto G too. Mostly people who use CM and tried to encrypt phone.
I downloaded Android SDK, fastboot.exe tool sees my phone in this state. Not sure if it can be used to do something useful....
adb.exe doesn't see device
Cyanogenmod is very buggy and in perpetual development state, not recommended.

Thanks, but I got stock Android and I don't want to loose my warranty :/

So, I left the phone in black screen step over night. Battery ran out. I tried turning it on/off, entering fast boot mode, but nothing happened, then connected to USB. LED turned on for a while, screen too, showing battery with 0%. But now nothing again. Just black or off, not sure. Can't do literally anything, I tried pressing different keys for minutes and changing USB slot.
EDIT
nevermind, fixed battery problem, Moto G with no power needs normal charger or much longer time on USB
From what I've read, encrypted data on phone is protected by password and some kind of encryption key/file. Reflhasing firmware would cause permanent lose of that key and thus whole encrypted data.
The only solution I guess is copying that key on PC. Copying encrypted data if possible, and decrypting on PC using some tool, as Android is open source, so it shouldn't be a problem to extract it's decryption mechanism and run it on PC.
OR copying key to PC, reflashing phone, copying back key and praying this time system will start.
Hello,
I've recently acquired a ZTE SmartTab10 and it was working just fine, after a software update started asking me for password. So it boots up and it says 'enter your password' on the screen. Thing is, there is no password. Empty doesn't work, any password from any of the accounts don't work, and I never even set a password.
While I realize this may be solved by formatting the device (I do have full access to the recovery), the data on the tablet is very important and unfortunately, only copy, so I'd like to extract it before I go ahead and evaporate the OS. Is there any way to do this?
- Recovery is stock
- Vol up + power gives me android logo with FTM in the middle
- No matter how I connect it to pc ('enter password' mode, FTM mode, recovery) PC doesn't see it as a device and I can't access files
Thank you for taking time to read this,
Have a great day!
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.
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
Flo
So my mom and I have the same phone, a Huawei P Smart 2019 pot-lx1.
The problem
The phone started doing a boot loop anytime you try to turn it on.
It vibrates and shows the Huawei logo like normal, but after the logo the screen turns dark (not off, just dark, the backlight seems to still be on).
Sometimes after this black screen, a 'recharging' icon is visible in red for a brief moment. It's a red circle with a red lightning symbol in the middle.
It does this regardless of whether it's plugged in or not.
I have no idea what this means because as far as I'm aware, the device can function fine without power (see further down below).
After this black screen or flashing the red recharging icon, it just reboots and does the same.
What I tried
The phone refuses to open Erecovery mode (hold volume up and plug in the device). I have confirmed that this method -should- work since I tried it on my own phone of the same model. In the case of my mom's phone it just shows a black screen like normal.
I can get the phone into fastboot, which is great. It tells you to open HiSuite on your computer, which I do, only for HiSuite to tell me "Your device is not supported for system recovery". Furthermore, any commands that could help me return 'Command not allowed', this is returned from the bootloader of the phone and is NOT an OS permissions issue. I've tried stuff like booting into TWRP or wiping userdata this way but it's simply not allowed.
Regarding the battery, I've tried unplugging the phone while it's in fastboot mode. It just stays on like expected and doesn't turn off, so I don't think the battery has no charge.
From what I gather online, the phone has an FRP lock which prevents you from doing anything that could result in the phone getting a reset. FRP can supposedly be disabled, I've tried dc-unlocker but it simply didn't work, presumably the phone is 'too new' because it wasn't in the model list. (I used detection & then the blue nuke option that said Temp FRP unlock or something like that). There are sites that offer FRP unlock passwords which can be used with 'fastboot oem frp-unlock XXX' but I REALLY don't trust these sites and the prices are expensive.
USB debugging is not enabled and I cannot possibly enable it because the phone will never boot, hence I cannot hop into adb and disable FRP that way or do anything else that adb could. I'm essentially stuck.
I also tried some random things like holding volume up + volume down + power during boot. I have also tried countless times to get into erecovery but it simply will never get to that point.
I also tried downloading the phone's firmware and putting all the files where the UPDATE.app is also located in the 'dload' folder on an SD. I also tried putting an 'update.zip' in the root, but this didn't do anything and I think it's pointless unless you can boot into erecovery.
My mom and dad suspect they damaged something related to charging the phone, either the pins or something inside the device by inserting the charger agressively, is that possible at all? It could explain the red charging icon regardless of battery status, but I'm really not sure.
Same problem!
Hi I have the exact same problem with my huawei. Could you able to solve your problem? If so, could you tell me how?
Thank you in advance.
