7028 titan rom firmware - Hip Street TITAN Tablet

I'm not sure either, and I'm almost sure you heard about Odin. Odin is a pc program that allow Samsung devices to flash stock firmware or unofficial ROM. Search for "How to use Odin".

I suppose you want to update to a higher Android version. I advise against it if you are a novice. First, you have to find an updated version of the ROM for your tablet specifically. Then, you will have to use an appropriate software to flash the ROM into your tablet. There is always a danger of bricking your tablet when flashing.

Most firms, don't make newer versions for Android tablets or phones. They only develop newer software for this new systems. For your tablet the version 2.2.2 is the latest.
The only way to get around this, could be you root your system. BUT this can be dangerous, because you can end up with a non functioning tablet. You can't root, with just any rom. You need a rom that was developed for your tablet. I could not find a rom, so perhaps the Android community did not think it was worth developing one.
If you don't have any experience with updating computers or tablets, don't even start looking for it, because one error and our tablet is bricked. (can't be used anymore)

You need to flash new firmware or the original factory rom using livesuit.

Can you tell me where you got the upgraded rom from, and have you tried downloading the firmware from the manufacturer's website? http://www.archos.com/us/support/support_tech/updates_fwm.html

Try to boot to fastboot and REflash a stock firmware.

Just flash the default firmware from the manufacturer:

Yes. Flashing the ROM does the same thing as updating your firmware. You are simply updating your firmware to one that isn't the original. All you do is load up the file from the velocity website onto your SD card and flash and you will be back at the standard ROM.
I suggest Macho ROM or JGM if you want the android market. Both run overclocked if you so choose which is much faster. JGM also has a vanilla rom (and there is and improved vanilla rom) which gives the tablet bare-bones applications if you want it to be just a reader. I would follow the method for flashing jgm. It lays out how to set up app2sd and all that.
4shared.com allows you to download apps that are not found in the market or whatever after you have rooted. Simply search the name of the app and put .apk at the end. Be careful as you can get malware from this. This method breaks copyright laws as all apps on it are offered for free and I only suggest it to download apps that are free on the market...
