wasn't sure where to post this but I haven't seen or heard anyone else having the same issue as myself. I've tried MIUI 8 and various CM13 Roms and the same issue seems to come up almost as if it is set on a schedule. So every time I get the phone to work it stays on for about two or three days without any issues but then it suddenly freezes, if I turn the phone off at this point and wait a few hours I am able to either get into FASTBOOT, TWRP or the MI splash screen. FASTBOOT and TWRP are able to keep the phone on boot the MI spash screen turns the phone off without even booting, If I plug the phone into the computer at this point the LED blinks red, and the phone is recognized as Qualcomm Hs USB Qdloader 9008 (PORT 3) which I assume is EDL mode or it doesn't recognize the device at all. When I leave the phone on for a little over 24 hours I am able to turn it back on and have it function normally for two or three days before the cycle repeats itself. Another issue I have is that the fingerprint sensor sometimes works and other times doesn't, in the sense that if the ribbon cable is connected to the motherboard the phone won't even boot, I've tried booting the phone without the fingerprint sensor being connected and it worked fine but as soon as I connect it back on the screen slowly fades out and all functionality is lost. I'm just interested to know if anyone has experienced these issues and if there is a fix for this.

Just wondering if anyone might have ran into the same issue as I have.
I own a Xiaomi Redmi Note3, at the time this issue started I was currently on Cyanogen 13 Rom with the fingerprint working fine along with everything else and after about 2 weeks I noticed my display turned off while I still had over 50% battery, and would not turn back on. At first I thought it was a battery issue so I tried charging the phone but the display remained off while the notification LED blinked red, after about 2 hours I was able to turn the phone on like nothing had happened while the charger was still plugged in and after about 2 more hours the display turned off again. After this second time I was not able to turn the phone back on for about 2 days and when I tried plugging it into the computer it would be recognizeed as HS-USB Diagnostics 900E(Diagnostics mode). At this point I thought I had bricked the phone and after trying every method I could find online I came across a hardware method to boot into EDL mode by unplugging the battery and usb ribbons from the board, this method also did not work at first but I noticed that when the fingerprint ribbon was unplugged from the motherboard I was able to force the phone into some kind of test mode where I could test all the hardware buttons and functions of the phone, I was even able to boot EDL mode, so at this point I flashed MIUI7 stable version but I noticed that now no matter which ROM I have flashed as soon as I connect the fingerprint senso to motherboard the LCD either fades to black or green and in both cases the phone is forced into HS-USB Diagnostics 900E(Diagnostics mode).
the phone was completely fine and working perfectly and then it started switching off all by itselfs, and then screen started fading and turning blue ,completely blue and unresponsive ,after rebooting problem was sometimes solving and rest times it just remain off and no matter what i do it was always off, so i unlocked bootloader unofficially by flashing that version 7.2 mi firmware of preunlocked bootloader rooted it intstalled google pixel rom and everything was fine for somedays and again the same problem, the phone was working fine in the night i woked up in the morning and saw that it is off and not working at all ,no response in pressing any combinations of the hardware keys no response on pluging it to the charger 2.4a/2a output pluging it to laptop.
only the response is when i open the back and unplug the battery cable and motherboard cable and then plug it again close it and plug the phone to a 1.4a charger.
and the response is a single red light once flashes that it,no continuous flashes no other flash just one time red light flashes thats it.
i would like to tell this that the phone has turned on previously on its own then only i was able to flash and move to a custom firmware.
Help needed.
Hey there. I found a bit old phone in my house, Huawei G730-U10 with MTK6582. Here's problem:
Phone won't turn on at all (no reaction) with battery in and USB out.
With battery in and USB in (connected to charger or PC, no matter what), at first it turns on red led that stays still, and after some time it starts vibrating with interval of about 10 seconds and PC sees it for 2 secs (it connects and after 2 secs - disconnects), then everything repeats. I assume it's bootlooping, but there's no anything on screen (it doesn't even turn on, full darkness). This continues even after taking out USB, only way to stop it - take out battery and place it back.
With battery out and USB in, red led starts blinking with very quiet beeping (very very very quiet).
As you could guess - recovery, fastboot and other things aren't working.
I've checked main board, everything is ok, connected and working fine.
I think there's problem in ROM (not firmware ROM, but ROM that's read-only memory). Something's wrong, maybe there's wrong preloader (or there's no preloader at all), maybe boot partition is damaged, I don't know.
Service center tried to fool me on buying new board for 100$ (althrough it costs 40 on aliexpress), I think they didn't even look at it, so I can't trust them.
I don't need suggestions like "try to flash new rom", you think I didn't try? How is this possible if I can't make PC to see phone for more than 2 secs? Flashtool isn't working even without battery mode.
Do you have any ideas?
Thanks for help.
Hi everybody, i'm facing a quite strange problem with a Meizu M5 Note. The phone has never been rooted and i've never attempted to flash custom Roms. I was using the phone normally, and suddenly the screen became grey, except for the status bar. I've restarted the phone and it returned to work. I used it a bit, then i locked the screen. When, after some minutes, i tried to unlock the screen, the phone was literally dead. It doesn't boot up at all (the screen remains black), so i can't access the recovery. By measuring the battery's voltage with a tester, it shows the right value (it was about the 60% or 70% when the phone "died"). I connected the phone to the computer and Windows detected it, i've also been able to install some drivers and now it's shown under the voice "Mediatek USB Port", but it continues to connect and disconnect from the pc. It seems like it's bricked, but there's no reason for it to be bricked. Has somebody got any ideas?
after change the screen,my meizu m5 note suddenly shut down and hard to boot,especially when i use data in it (wifi or cellular data).strangely,when it connected to charger,it appear quite normal.not suddenly shut down.anybody knows why is it?is there any problem on LCD or the battery?
I bought a Cubot Power at the start of December, and I was quite happy with it for a while. Two days ago, I decided to install Greenify to test it out on a non-rooted phone, but when I tried to restart the phone, during the boot screen the phone froze for a moment and after that I couldn't do anything else other than stare at the black screen. Surprisingly enough, the next day my phone had it's screen on (had to insert PIN from restarting), and got to use it for a couple of hours. Then it froze again, and after that I haven't gotten it to work.
I'm not exactly sure what happened to it, unlike my previous phones it does not vibrate when turning on so it's hard to tell whether it's stuck in a bootloop. But when I do connect it to my PC with an USB cable, my PC starts making the device connect sound, only to disconnect a couple of seconds afterwards. When I open up device manager, I can even see MediaTek driver in there, which disappears with the device disconnection sound. I can't get into recovery, I've tried using the volume up + power button combination, but with no results (screen still remains black).
I've tried to use getdroidtips guide to install stock ROM on my Cubot Power, but no matter which stock firmware version I use, flash tool gives me an error "STATUS_DA_HASH_MISMATCH".
Does anyone have any suggestions what else can I try? It would be a hassle to send it back to get it fixed, as I ordered it from half across the world.
