UMI Z does not turn on and does not charge, it has a blinking red LED

vicente_mateus

I was using my UMI Z, suddenly when I went to open an application, the cell phone turned off with approximately 50% battery, then when I tried to call the cell again the name of the UMI appears for 1 second and then the screen goes off, no matter how many times I try This will always happen, when loading the battery appears for 1 second and the screen turns off, but the LED always blinks red when connecting to USB on the computer to try to use SP flash and reinstall android, Program does not recognize the cellphone, and the drives are installed because I did a downgrade about 20 days ago with the flash sp due to the update 7.1 is closing all the programs all the time making it impossible to use after the downgrade was using normal until it happens Is there any solution to apply to this problem? Otherwise I will check what can be done under warranty, the UMI Z apparatus are in many problems unfortunately.

LED only blinking when battery was completely discharged and is in "recovery" state. This should take around 15 minutes on genuine charger and then stop blinking and start charging.
I would charge phone for few hours then try restart phone still under charger. If phone fail probably you have poor battery contact or battery failure.

Hello, thank you for replying, I've left it load for more than 3 hours, the red light is flashing and the battery design appears for 1 second and it goes out, it stays that way during all the mobile charging, if I try to call it appears the logo of the UMI For 1 second and then erase, see the youtube video in the link below to understand better ... I do not believe it's a battery, because when I enter the menu for hard reset it has 3 options (recovery, fastboot and normal) when selecting recovery and normal , Appears the logo of the UMI and the cellphone turns off, but when I click on fastboot the cellphone does not turn off, but it is locked, so I believe it is not a battery, if it was a battery I think the cell phone would not keep connected, Software? Bootloop? But SPflash does not recognize the phone, I already installed the drivers even before I had downgraded the same computer before, I had recognized the cell phone and everything worked out, now it does not recognize because the cell phone does not stay connected.Video UMI Z

\n\nI have the same problem. The phone didn't come up even for the first time. Red light blinking, never turns to green when charging. Do they test devices at the end of the production line at all? I didn't even see the initial screen yet.

Of course that the phones are tested during and after assembling.
Green light will come on when battery is fully charged. Please switch off phone connect charger and wait for around 3 - 4 hours. After around 15 minutes red light should stop flashing and start glowing also after short press on power button screen should light with battery indicator. If this is not working I would recommend flash whole system with SPFT and if this not help too then is hardware fault.
Here is SPFT instruction
