[Q] My Phone is complete Bricked, help me pls, nonstop restart

hi guys, (LG-P920 is my Phone)
yesterday i installed ROM MANAGER to install CWRMOD (or something like that).
Then i choose my Phone Type and flashed it. After that my phone permanent restarts in 1 second,
showing LG Logo and restart, restart restart nonstop.
I understand that i ****ed it up with flashing that recovery mod. So i decided to Plug into my PC
and install everything new, but when i connect my phone to PC , it detects a unknown device every second and does it permanently too. I tried the "Battery out, Volume Button UP and connect" trick, then it stops acting weird but my PC
dont recognise my phone as OMAP, it is just an unknown device
What should i do guys? i tried installing LG Support Tool, LG Mobile Driver, and i read all the Instruction to UNBRICK your phone.
But all the Instruction starts with a successful regocnition of OMAP driver, but my PC dont even recognise it as OMAP.
PLS HELP
ok i fixed it, it was a really complicated move to 0.1 sec click that omap and install while my Phone was permanent restarting.

[HELP] MTK USB PORT but no Preloader USB

I have a BIG problem with my Pixi 3 4.5 4G... I was trying to change the rom to the stock one, and I did it successfully, It never boot again It was stuck at the "COMPANY LOGO" so I star the whole process again, what happened is (This was very stup...) I click on the "Format Whole Flash" after that the phone is dead (just the led on the screen is working), I just use FlashTools to put the stock ROM again (so that means that Preloader was working fine at this point) and after the "Format Whole Flash" Im unable to get anymore the Preloader, and I try with a different Phone Just to check if the drivers was working and yes it is, so now I cant access on even recovery mode.
Note: The MTK USB PORT never change to PreLoader USB VCOM Port <Thats what Im looking.
same problem here!

How to unbrick a hard bricked lenovo a3300 tab?

My lenovo a3300 was flashed few months ago due to some rom problem by service center (and it was showing rooted while I checked using few apps).
Yesterday I tried to upgrade my firmware(available in phone update) but while restarting, it showed the boot screen and then I tried reboot now option. But then No command and a lied down android bot appeared.
None of the other option worked, and after 30-45min the screen became off and from then showed nothing. I have tried every possible button configuration but they failed.
I have inserted it into computer and system recognized it as a "MTP USB device" under portable device(win 8.1) .
But today it showed the start screen too(finally, hope ) and I tried to reboot it by holding the power button. But the same screen returned after a vibration.[it used to vibrate when switching on]. When I right clicked the "MTP USB device" It was showing update driver, uninstall etc.
But after I tried to reboot(also after disconnecting and reconnecting it) , there are only one option i.e. "Scan for Hardware change".
I have the sp flash tool and the stock rom from xda site. I have also installed VCOM driver (android gadget vcom driver) but while flashing the download is not starting, though no error or popup showed.
How I can get my tab work again? pleaaaseee help
Thanks in advance
