ok so im posting this for my boss who is asking for my help with his galaxy tab. He wanted to put an ics rom on it. he flashed it without wiping. it wouldnt start from there but thats not the issue i bring to the table. We cannot get into recovery but we could get into download mode. I thought we were safe. we went to push through some firmware and when we restarted it, we hear the sound of it coming on but the screen remains black. We have a few possible ways to fix it but since the screen does not come on we cannot get it back into download mode to push any updates, firmware, or roms etc. So im asking if anyone knows how we can get back to download mode or just get the screen to come on. Any help would be appreciated.
