Bricked after mistake when flahsing. Can't connect to pc.

Hi everyone
Just 2 days ago i got my Galaxy W. Yesterday i decided to install COW rom.
So i followed the instructions. I rooted the phone which and after that i had to flash ClockworkMod v5.5.0.4. However i didn't follow the instructions as i should and i didn't extract the file from the zip archive. So i put this recovery-clockwork-5.5.0.4-ancora.zip file in the internal storage of the phone. After that i performed recovery-clockwork-5.5.0.4-ancora.zip manual flash with adb shell for the zip file. After restarting my phone the samsung logo showed up and after that i was in the download mode. I can't get into the recovery mode. Now i can only get into the download mode or ramdump mode.
When i connect the phone to my pc it is marked as unspecific device which means that i can't do anything with it. I tried connecting it to mac, ubuntu, win 7 but i got the same result. I tried using One Click UnBrick program but that didn't help. The odin doesn't recognize my phone as well. I have also reinstaled drivers, kies but with no results.
So far i haven't found anyone with a similar problem.
Is there any chance to unbrick my phone? Or should i just take it to samsung service?
Uninstall drivers. After install them again. Use another USB Port, for best result one of the backsided ones. Put your phone into download mode, start odin, connect phone to PC, flash stock rom.
worked for me and for my friends SGS II also. I'm hoping for that it works!

Forgot to mention, restart after uninstalling drivers und again do a restart after installing drivers and uninstall kies, sometimes it disturbs odin

have u try to go to download mode? (turn off device, press volume down + home + power)
I never had a problem for that, just get in to download mode, connect it, then Odin will read it automatically
Similiar with my problem before, but in my case when i turn on device, mine showing false download mode. I can't go to download, but only showing menu...
Have you go to download mode with voldown+power+menu key? Or just use 'false' download mode?
Sent from my GT-I8150 using XDA App
I get into the download mode by pressing power+vol down + home and after that a menu shows up and i press vol up. Then it says:
ODIN MODE
PRODUCT NAME: GT-I8150
CUSTOM BINARY DOWNLOAD: NO
CURRENT KERNEL: UNKNOWN !!
Downloading...
Do not turn off target!!
Just tried connecting to Odin again without success. Any other ideas?
omg im so happy.
Odin somehow detected my phone and i reinstalled it.
Thanks everyone

Help required to get my DHD back to stock

We recently have purchased DHD, and it was pre-rooted, we are general users and don't need any high end authentications in our phone to keep it stable, since yesterday I am searching on things how to get back to stock, finally tried AAHK, and pressed 1 at main menu, it rooted my phone again (I guess), but now it is blank (black) screen with no text after green colored htc logo and white background, it just blurred and turned screen into black, and halts in there,
What I tried before posting in here:
1. tried same thing again to flash using AAHK,
2. downloaded ARHD 6.x but no idea how to install it when I have no screen.
3. When I press volume down with power it takes me to bootloader, but automatically searches for some PD98IAG.zip (its not PD98IMG.zip)
and keeps searching it, (in other words it halts there as well)
4. restarting / switching memory card, googling.
I don't know if it is allowed here or not, but I am open to any payments if it costs any, for the one who can really get this thing fixed for me.

Diconnect the phone. Uninstall all HTC drivers from the computer. Install the HTC drivers came with AAHK tool. Switch on the phone in Bootloader. Wait until it stops scanning the SD card. If it never stops, pull the battery and remove the SD card from phone then switch on the phone without SD card. Once the phone is in Bootloader try connecting the phone to the PC, then try to falsh the RUU that you have downloaded.

Cant get into download mode,

Im able to get into twrp recovery, and fastboot mode but not download mode... I wanted to put the phone back into stock and i thought wiping out everything would do so but i guess not.
Whenever i press the download mode command which i did was volume up down and power then plug into the laptop the 3 buttons will flash but my laptop won recognized it. I tried installing the LG Optimus G drivers but still unable to install it. Also TWRP says that the phone isnt rooted anymore and has no OS.

First off it's Vol Up + Vol Down while powered off and then plug into computer. DO NOT press the power button.
Secondly what ver. of windows and did the computer have any issues prior with connecting to the phone?
There is another fix but it's a bit drastic and wouldn't recommend it at this point.

oh well that might be the reason why. il try it out..im using windows 7 and it was working before i wiped everything.
link me to that fix if anything thanks
On my phone, Download Mode is only accessed when Vol + and - and power from a powered off state, while any USB cord is plugged in, either to a PC, or a wall charger.
After flashing, i noticed that the phone has some issues powering on and off normally i.e. phone completely died, plug the phone into the charger, screen turns on, phone is theoretically charging, but does not show any charging display icon. Which then forces me to unplug the phone, press and hold the power button for 10 seconds, press and hold the power again to turn the phone on, and immediately plug it into the charger in order to get the phone to normally boot up. I flashed CM 10.2 from the original android dev thread. I think that was just a design flaw that LG had originally, but meh, what can i say.

[Q] Booting problem

hi. I encountered a problem on my phone that doesn't boot properly.
When i tried to switch on my phone it showed at first the welcome msg "Samsung S4 mini gt-i9192" then after that, a pitch black screen, could not properly boot. But i learn that it does not turns off after the screen turns all black, i have to press the power button first to turn off the phone.
This problem started when i installed an app with some compatibility problems.
I wanted to root my phone hoping that can solve the problem, but then again a problem occurred when i tried to connect my phone to my laptop. It fails to install MTP usb device to my computer. I tried connecting it again provided that samsung kies was installed but again failed to connect my phone. Therefore i cant root my phone because i cant copy the files needed to root to my phone sd card.
I tried reinstalling kies, installing mtp drivers but nothing happened. I tried also restoring the previous boot image, restoring factory settings using recovery mode. But then problem still exist.
And fyi my phone can't mount any external sd card using recovery mode. And i think it was not in a debugging mode.
Phone: samsung s4 mini gt-i9192
firmware: i dont know
So basically, the problem is:
my phone wont boot,
i cant connect it to my pc
and i cant root it.
How should i root or even flash my phone when i cant connect to my computer? Do you have any idea on how to solve this problem? Any solutions or suggestions would be much appreciated. tnx.

Have you tried putting the phone in download mode (Volume Down + Home + Power) and then connecting it your p,c , if not give this a shot it should pick up the drivers , once done , take out the usb cable hold the power the button to shut down and boot up .
since you have not mentioned your OS am assuming it is windows , try taking out Kies via some software like revo uninstaller which will remove all directories plus all registry entires then reinstall it if you really need it.

dial *#0808# from your cell this would take you in usb settings, tick both mtp+adb , reboot , if they art already ticked uncheck them and check them again.

yah, thats what im thinking. i just brought this here hoping to solve this problem without going to a shop. thanks anyway.
aac. To me put your phone in download mode then use moborobo(a windows software) . Just open it and it will install the driver. If it dies not work then use adb installer . Remember you should have only any one of the software at one tim means either moborobo or kies or adb installer

btw have you tried to boot the phone in safe mode ?? if it boots in safe mode it is still fixable without going to service center. power down , power up+ tap the menu button 3 or 4 times at THE same time to boot into safe mode if it boots into safe mode that means the hardware and OS is fine if it does not well then your out of luck.

What did you flash, what error does it display, is it "secure boot error", which version of g3 do you have, can you access recovery, do you have TWRP...?

i used ioroot to root the g3 (D855), and i flash with twrp-2.8.0.0_d855-signed.img. Yes i believe it was the secure boot error. After that the notifications lights at the topped flashed blue and red i turn the device ofd to restart and it will not turn on i have tried both to get into the recovery menu (power+vol down) and download menu (power+vol up) neither of which is working.

Ok... Lets start with battery pull in and out.
Even if you do recive secure boot error for booting to the unbumped recovery you should be able to boot to the OS, try with that.
If this fails, do the battery pull again and lets try to get you to the download mode. The way you specified (power+vol down) is incorrect I belive. What you need to do is hold the volume button WITHOUT the power button which will be followed by connecting the device to the PC with installed LG drivers.
If that works you could flash stock files, follow the thread: http://forum.xda-developers.com/showthread.php?t=2785089
Check in device manager how is the phone detected what mode ...

Does it get into download mode? For this one get the battery out and wait 2 secs. Plug it back in. Be sure to have an USB Cable ready plugged in the back of the PC (NOT IN FRONT HUB and be sure to be the original Cable). Hold Volume UP and Plug the cable. Keep holding Volume UP until you see download. Tell me if you see the Firmware Update screen or it is a security error.
