Samsung i600 falshed with i607 - i GIVE US100 FOR A SOLUTION

I have just flashed SGH-i600 to a SGH-i607
During the flash process, everything was OK. The 3 digit counter kept running, before i removed the battery.
Now the phone starts and reboot....
I put in bootloader mode and is not recognized....
When I try the Bootloader mode, I have only :
*USB Downloader-Xcingular V1.2
[Phone] Active OFF
I have tried to download the modem driver and lot of things but I can do nothing. The phone is not detected by my computer on USB.
I think that I have to replace the boot loader! Perhaps with the MicroSD....
Can someone please help me!
In advance thanks a lot
Hi,
I have a very similiar problem. My i600 is not booting anymore and the update sw does not recognize my device as it seems to require the activesync part to work on the device.
Does anyone know how to install the firmware in another way?
thanks for answers
best regards
I gave up and got Samsung to replace the motherboard. It was a pricey mistake.

[Q] Computer no longer recognizes USB

After flashing EB v2.5 I could no longer acess files via usb cord, I have since switched to Phoenixblood v1.1 with the same results. Upon searching for similar issues I have found there are many people with this same problem and cannot seem to find a resoultion, I have tried different drivers with no luck. Here are some qoutes from others with the same issue:
I love it! It's the fastest rom I've ever used! But like all other roms I flash I cant use USB mass storage . suggestions anyone?

I am having the exact same problem. It only charges. Other than that there is no other indication either from the computer or the phone that it is even plugged into the computer. Really cramping my style. I am sure I speak for you in saying anyone's help on the matter would be greatly appreciated.

Hey all thanks in advance for any help. Ive been using weapon for a while now but got sick of the fc's so decided to try out eaglesblood. Ive installed it twice now and followed the instructions each time but I cant get my computer to mount my phones storage. It does make a noise when i connect it, so i know it sees my phone. And my phone gives me the option to use as mass storage but nothing happens. Any ideas? Does anyone else have problems with this?

Different USB? Sometimes they can "die."
I tried a different cable and a different computer with a different op sys
just for the sake of troubleshooting, can you take a screenshot of your device manager before and after you plug it in? I had my phone randomly do something similar, but I just wiped my system and reinstalled the drivers and all was fine, different problem than yours but any information you can give us is helpful.
happened to me... what i did was turn on usb debugging with the usb storage and apparently it work...
I noticed I couldn't mount USB mass storage on CM7 or clockwork recovery....using multiple computers. I fixed this by installing the LG USB drivers on my desktop....I've had no issues since. Though I had previously tried the same thing with my laptop and it didn't work.
If turning USB debugging off then on doesn't work I reinstall the drivers. Its happened to me once or twice and that seems to do the trick.
Get my app: Speakerphone Volume Control

BRICKED - unstable usb connection - OMAP443

i am loosing it....
i tried every thread about bricked phone - and nothing solved my problem.
it all started when i tried to use th LG FLASH TOOL to upgrade firmware and by mistake i checked "Erase Entire AP" and since than my phone wont turn on.
when i connect the usb cable - i get a notification of OMAP443 but it goes on and off rapidly like it is connecting and disconnecting at the same time - not stable.
i download all drivers, even tried to manual fix the driver with the inf file, but nothing - still unstable.
i also bought a special usb cable that has 56K-130K-910K - i tried all modes but did not get the download mode screen as shown in one of the guides here.
i need to stable the connection between the phone and the pc so i can flash the firmware.
any suggestions ?
please help - anyone :crying:
You have probably used Smartflash,not Lg flashtool.
I can make your phone to stay connected to pc but you won't be able to flash anything
Your phone's cpu is in debug mode now.
Signed bootloaders are needed to recover it with Linux, or a script for omapflash for recovering with windows..

Hi,
You can try installing USBDeview and remove all previous instances of Micromax A110, Mediatek, etc.. from your system, restart the system and then connect again phone to your system using USB cable. Your problem may get resolved.
Google for USBDeview software or get it from here
Hit thanks, if I helped.
thanks @priyarupesh i will give a look at it thanks

[Q] Stick won't connect to PC/ Am I screwed?

Hi all,
I'll try to keep this short, I am new to this and if anyone can help/point me in the right direction to find a solution it would be greatly appreciated.
I bought an mk809iv off of geek buying (I wanted to link the page of the stick I bought, but since I'm new here I can't)
I tried rooting it but jumped in too quickly and now nothing works. It doesn't connect to the PC or television. USB debugging is not checked on the stick.
I tried rooting with an Eazyroot image from an usb stick and got stuck in boot loop, then I found a rom that was said to be working and tried flashing it with RKbatchtool 1.7 and the drivers that came with the pack. The stick connected to my PC, i tried the to flash it, but at the end of the process i got flash failed as a message.
Now the PC doesn't recognize the stick, so even if i can find a rom (stock or otherwise) I can't even try to flash it.
Is it possible that I wiped the stick clean and that's why the PC wont recognize it? I have been reading a lot on fastboot and ADB, and am wondering if I could fastboot the device so i can load a new kernel (?) onto it so it would finally communicate to the PC.
Am I wasting my time with this? Is there anyway to get the stick to work again? I'll keep reading but if anyone can help or tell me where or what to look for to learn what I need to do to get it to work, it would be really appreciated.
Thanks!
* Edit: After reading some more, I seem to have hard bricked my stick... So just in case, is there anything to do or should i just throw it out?
