[Q] turn on usb debugging mode of a Nexus S stuck at google screen (soft bricked)

My Nexus S is stuck at google boot screen. Only fastboot commands work after connecting to PC. Problem is fastboot mode does not have recovery related commands, but only ADB has. But to work on ADB connecting the phone through PC, USB debugging is to be enabled.
In my case it is not done (before phone is soft bricked) and I have to turn on this somehow so that I can get into recovery mode. Please let me know if there is any way to do this. Please help.
Thanks.
plz help me too
i too got the same problem as described above plz help me

[Q] Pantech p9090 discover bricked!

Hi everyone!!! Last week i tried to upgrade my ICS stock rom with jellybean, but my phone powered down! Now the Pantech doesn't power up. No bootloader, no fastboot. The computer doesn't recognize the device (i have all drivers installed on). but, when i connect for the first time the usb cable, my pc installs the QHSUSB_LOAD drivers, and then, after 2-3 seconds, it gives to me an error (exclamation mark)in the Device Manager for this driver. It displays an error also to the pantech ADB interface. My Phone is dead. I connect usb cable and it gives three quick sounds (no device connected). HELP Me, please!!! Thank you! Alf :crying::crying:

Need help fixing Lenovo Vibe X3

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!

Greetings and welcome to assist. Did you do anything to your phone before the bootloop? Also if you put your phone in download mode is it recognised in kies/smartswitch emergnecy firmware recovery ?

Tried to unroot the phone before.The USB/charging port is broken,fast charghing isnt working anymore,thats why the phone isnt recognized at all.I will change the broken piece then it should be recognized by pc and i can reinstall the android.also'the motherboard can be damaged.anyway,the phone quality is very bad,i had a lot of problems with it,ill never buy a Samsung again.
