Hello, can you help me?
I am having a problem with my huawei honor 3c, I think it brick.
In brief, my phone won't start up no matter what I do, the display is completely shut off, the pc doesn't recognize the phone and it only flashes a red led for one second as soon as it's connected to the pc (without the battery), then nothing more happens.
I reinstalled the drivers and changed the usb cable but it's still not working.
it all happened when I was flashing a ROM using the sp flashtool, it was working fine but as soon as I disconnected the phone and reconnected it back to the computer, it didn't work anymore.
may someone please help?
Hello, for some reason i cannot get my phone into fastboot. The main problem is that my PC with Win10 x64 does not find any device when i plug the USB cable in.
I have read in many forums that i have to discharge the battery so that the red LED blinks and then plug the USB. This is the case, but no device is found by windows...
any tips on how to get the qualcomm thing work so i can use MiFlash to flash an official ROM?
Almost impossible to loose fastboot, what did you do? Have you done this before? Are you sure windows cant find your device? I had a problem that for a few hours after brick my phone, windows didnt recognize my device as Qualcomm device... windows recognized my device as "something I cant remember", and suddenly after I connected my device to wall charger for a few minutes, suddenly apear in my computer as qualcomm device.
probably a dead battery or broquen usb port. try another cable
Hello everyone! I brought a Lenovo Vibe X3 (x3a40) 3 months ago. And I updated it to MM 6.0.1 and the bootloader was unlocked and the device was rooted. TWRP was also installed. So I installed this CyanogenMod 13 from HERE.
Then I missed some stock features and decided to revert back to stock MM. And I used QFIL to flash the official stock ROM. But it turned out that QFIL suddenly stopped working and my device got stuck in EDL mode. Once I turned it off completely to flash it again, the device wouldn't boot up. In my case the device should get into EDL when I connect the USB cable and immediately hold the power key for a second. But there is no response.
Usually while booting the device vibrates but now there is no vibration nor is there anything on the display. The screen keeps completely off and it wouldn't boot into any mode, like no download/no recovery/no EDL/no bootloop, just cold.
And when I connect it to the USB all I get is the "Device not recognized" error. In device manager I get this "Unknown USB device (Device Descriptor Request Failed)".
Please note that I've tried switching the USB cable and the port as well as on a different PC and also checked with the drivers. Still the same. If someone could help me, it would be a great help.... :crying:
Further info on the device is here!
Hello guys,
I am facing strange problem on my Mi4. I have connected my Mi4 in fastboot mode trying to check if bootloader is unlocked and I made a typo "fastboot lock" instead of "fastboot unlock" ? and my Mi4 went to black screen with no sign of booting.
I am still able to connect via fastboot and PC shows my Mi4 as Fastboot device and I am able to do commands in fastboot via CMD but I cannot see anything on the screen, it is just black but I can see the white light from back side od screen when I open Mi4 case so it turns on but not showing anything. MiFlash can see my device also as fastboot, no COM drive mounted in MiFlash so I can't flash Fastboot ROM.
When I plug phone to charger, I can see red led light but Mi4 seems to be bootlooped, it restarts all the time.
Any tips what should I do?
you can try Qualcomm HS-USB QDLoader 9008
it is a factory mode it may fix it
but i am not sure
Same problem solved on my mi3w
After "battery change"
Before that
I tried 9008 deep sleep cable (search on YouTube) didnot work
I tried testing points connected didnot work
After one week I buy a new battery and put it in my device
Its worked
Hi. A friend of mine has Honor 8 (FRD-L09) and one day it just suddenly died during usage. And I mean completely died. It didn't even show up as an usb device. I replaced the battery and the usb port and now I can see the device listed when I use command lsusb on my Ubuntu laptop. But that's all. The phone won't charge, won't turn on, won't boot into fastboot... Nothing. The phone was not rooted and adb was not enabled before the phone died. Is there anything I can do to recover the files from the device or to make it boot again?
