    Hi all. Newbie to this forum here, I came here after a search to identify a tablet that was given to me. The tablet is bricked and I am not sure if i am going to be able to get it going but I am sure going to try. First step is trying to figure out exactly what it is. Here are some photos I took yesterday.

    I need to know some things about this tablet. What is the model, what firmware/ROM do I need to flash. What are the speks on the charger? Volts? Amps? The previous owner lost charger and tried making a new one from phone chargers. I have the connector that fits the DC jack on the tablet and three 5v adapters from the previous owner. One is 5v 2a. When I plug this one into the tablet a red light comes on. I guess this indicates that it has power. I have left it "charging" over night like this. Nothing happens when I push power. I am guessing that the adapter is not right somehow.

    Can anybody help?

    PS. Sorry for the way I linked photos, had no easy way to do it other than that.

    Jonathan

    Hi Jonathan, congratulations on your new tablet and welcome to the forum. Nice of you to become a member of Android Tablets. If the cable you have has a USB connector on the other end, try charging it from a PC. It may take a while, since the USB port will provide less power than a charger normally would. When you "push power", hold the button in. Just tapping it only works if the tablet is asleep, not when it's turned off.

    Thanks for the response. I am in the process of making a USB cable that has a male on both ends from two scraped A/B USB cables. I plan to try charging it that way. The cable I have does not have USB. Simply a short whip with a connector that fits the AC port on the tablet. I know once I get it booting, I will need a rom that works because the previous owner deleted something "In his words it would not get past the android logo". I am thinking if I can get it at least that far i should be able to find a rom for it providing I can positively identify what exactly it is. Yes I did hold power button. I have some experience flashing roms from my recently diseased OG droid and my HP Touchpad.

    I discovered that the cells in the battery are drained down too far for the circuitry to stay alive. I have seen this before. It should come back to life after I charge the cells up with my hobby charger. Just want to do it when I have time to be nearby to observe them as they are charging up. Don't want any nasty accidents. After I get it booting up, I was hoping to get somebody to do a nandroid backup of their device then I could get that and flash it into my tablet. Not sure if I will be able to get a doner or even if it's going to work. From what I understand the previous owner tried installing a rom from a Samsung Galaxy. Hopefully he left the original backups in place. Will have to wait and see.

    Ok so that didn't work out. The individual cells are ok as tested and charged by my Triton2 hobby charger. Voltage of the cells combined reads 7.5v. but the leads going to the tablet read 0v. There are two tiny chips on a board which the leads from the battery and the lead going to the tablet is connected to. One of those chips must be fried. Any ideas where I could get a new circuit board for two lipos? I guess I will have to check what a new battery costs. Wish there was a way I could test the tablet first before I sink any money into it.

    I guess I can just rewire the leads on the battery for now. Then I can test the tablet. It'll work as long as I don't try charging it with the leads directly on the battery.

    Ok so I got it booting. I see android world with lights flashing around it. Looks like it is stuck in a boot loop. Weirdest thing I saw TUX just as it was booting up. Not an android as I would expect from an Android tablet but Tux from Linux. Weird.

    Ok I got it booting then I tried all the button combinations I could think of till it finally quit booting again. I then lifted the main board out to take a look at the other side. I found a few interesting things there.
    This photo shows the entire back side. There is a micro SD card so hopefully, if I ever get it fixed, internal memory is upgradable.

    This is a closer view of the cpu section Take a look at the three yellow pieces above the MX chip. The centre piece looks fried.

    The CPU itself.

    There is another area where I found a tiny "something" that looks fried. I tried to take some closeup pictures of those areas. Take a look.

    Take a look at the row of resisters near the trxcom unit Not the closest row but the next. The second resister looks like it got warm.

    It's tough, but repairable, I don't have anything to lose. All I need is to find out what those pieces were and find replacements. Still waiting for anybody to ID this tablet for me.

    Well, nobody can accuse you of being a quitter Jonathan.:rolleyes: Looks like there definitely are a couple things in there that got fried. (Maybe a charger with too high a voltage?) You did make a little progress though, the tablet is based on an Infotmic processor. That could mean it's a Wowpad/Flytouch II or possibly a ZT180/Elonex. Unfortunately, if I recall correctly, there were also a lot of generic clones of those tablets.:(

    I guess I'm just not bright enough to quit while I'm ahead. I don't need the tablet as I already have an iPad air and an Jo tochpad. So it's just about the challenge I guess
