Hello guys, i have a Tecno F8 mt6589 that got bricked in bootloop and continually reboot from the logo screen. I dont know what happened but i can access its recovery mode and the factory mode. i tried a lot of things to make it discoverable by my Windows 8.1 PC but this is what i see in the device manager: "unknown USB device (device descriptor request failed)", Trouble shooting doesn't work.
When i boot into factory mode and made an auto test, the test result is:
[ x ] eMMc
[ ] Wi-Fi
and when i select the clear eMMc option it will just show formatting eMMc and suddenly, within less than a second, the phone reboot with continues bootloop. I dont know what happened with the eMMC
While in the system recovery mode i can do anything but i cant use the apply update from sd card option.
Please i need your help
Also, there's no sign of detection when i switch off and connect the phone to the PC, even if i remove the battery and replace it back. The phone only start as if its going to start charging then continue to its bootloop upon the connection. It is only discoverable as "unknown USB device (device descriptor request failed)", when i boot into either the recovery or factory mode.

Like so many others, i've tried to flash an incompatible rom to my chinese mtk6589 1gb ram 8gb rom knockoff device. (bought on amazon, called newisland) here is the model no.: Alps 09_v89_jbla828_hd
I rooted it correctly, I have the correct drivers. I installed cwm recovery.
I believe I backed it up on mtk droid tools, but i'm not sure it saved correctly.
The first few roms I tried got stuck on a distorted brand page, but at least I was still able to access cwm on the device.
My current situation is as follows:
black screen, device doesn't react to trying to load cwm. When I plug it in, I get a red battery-charging light.
when I connect my device to my windows 7 64-bit computer via usb, I get the sound that the phone is attached. After about 10 seconds, it sounds like it is being disconnected, but it's not. Then it re-connects, disconnects.
I had uninstalled the vcom drivers through usbdeview, and now I am incapable of reinstalling them. The only indication in device manager that my device is connected is under “network adapters” where it shows up as “alcatel single rndis interface #7.” this alternately shows connected/yellow exclamation point corresponding to the connecting and disconnecting sounds of the device. The drivers and the device itself never appear in the list, not even for 2-3 seconds.
Trying to load the drivers independently leads to the message “inf does not support this method of installation.”
spflash tools doesn't show the device as connected.
My questions:
1. is the device a total loss?
2. can I possibly revive it without using the touch point method? (I can't seem to detach the cover even after I unscrew all the screws)
would appreciate any help I can get.

Help please! I was trying to install a custom touch recovery with Odin, as soon as i flashed it into my phone, my phone stopped and now I am unable to enter recovery or download mode, the PC doesn;t detect it and it won't boot, just shows the samsung logo with the phone model name (Galaxy S Advance). When i connect my phone to PC it just shows the loading wheel, and from that point I can't do anything with my phone, I have tried all the possible methods of connecting my phone without battery, turning it on before connecting to the usb cable etc. I also reinstalled the drivers but without success.
Please consider these issues:
*I can't enter download mode or recovery mode;
*The PC doesn't detect my phone;
*My volume buttons don't work. I used to enter recovery and download mode via adb and 300k tool, but now my phone is undetectable by PC.

Hi,
My phone is bricked (totally dead+usb not detected+doesn't boot at all) because i formatted it without installing the new rom. (sp tool was taking too much time and I had to stop the process)
now the phone does not have a rom installed and I cannot boot to recovery mode aswell. everything is gone !!
and the biggest problem is that my pc has not been detecting the phone while it's plugged in via usb cable since i formatted it. :crying:
maybe, can i just install the rom in sdcard then i boot from it?
my phone is versus pioneer p1 ( a.k.a gionee pioneer p1)
Thanks.
Hello,
Welcome to XDA.
If your device doesn't charge, has no LED when plugged in, won't boot to any mode, no vibration when press power and PC gives no sound when device is connected then you are probably hard bricked, if that is the case you'll have to take it to a repair shop, there is a good chance they won't be able to fix it.

I have a zenfone C, it is bricked now. When I turn it on, it shows the Asus logo, then bootloops after a minute interval. When I connect it to pc, the charging icon appears. I cannot enter into recovery mode, and I cant flash a new rom because it cannot be detected by pc. I have intalled isoc, including usb drivers but still cannot detect. This fone has no warranty anymore.

Hello, and welcome to XDA!
Since you cannot get the device to recognize on a PC, I doubt this will work. From my standpoint, it is your last hope:
> Android Development and Hacking > Android Q&A, Help & Troubleshooting > Asus Zenfone C bootloop
If you run into problems, can reply in that thread as well (once you have an XDA account).
Hope this helps, and good luck!
Can anyone help me on Getting My LG G PRO F240L back, it stucks and always restarting on CWM RECOVERY saying "Device Unlock! So Boot Success!"
I've tried to Flash KDZ LOLLIPOP using LG FLASHTOOL 2014 but stucks on processing . I Bet the problem is the "UNIDENTIFIED DEVICE -> NO DRIVER FOUND" When connecting it to Windows 7 Ultimate, I went to Device Manager and sees "UNKNOWN DEVICE" I Uninstalled it and Tries to Connect again to DOWNLOAD MODE but Unfortunately " NOT RECOGNIZED " the device I have changed different USB CABLES and restart the Laptop Several Times . I manage to UPDATE the DRIVERS but the Problem was I can't connect the Pocketwifi via Wireless Connectivity, I can Connect it with The Cable Inserted on the Laptop but Where the Phone should Get into Download Mode by the Laptop IF there's an inserted pocketwifi on it. Please Help who knows what to do with it... Or is there something that should Fix my LG G PRO that Stucks on CWM .
