[SOLVED] Flash custom ROM with ADB - xda-developers
maybe these instruction can help you repair nand
[DEV] Custom kernel for Dropad/Herotab - SlateDroid.com - Page 4
The last post on this page seems promising, but to even do that you have to have already soldered on a serial port connection, which I believe I've found the pads for as well on our board. as far as that post, I haven't taken my tablet apart enough to flip the board over to see, but I'll give it a try when I have some free time. the dual switch that mg3100 talked about seems like a good idea, not only would it make it really easy to fix if the the tablet is bricked again, but much as they are developing there, would make it easy to try out other OS's without screwing up your nand.
nefirim, maybe it's not necessary if we manage to build a working u-boot-sd.bin for our tablets (and if Coby didn't disable this somehow in their boards):
[GUIDE] Revive your dead tablet - SlateDroid.com
From what I read they figured out that the soldering isn't needed as long as you format and copy the external SD the right way, and put a working u-boot. Please correct me if I am wrong.
You're not exactly wrong. this actually worked for Arlic once when this happened and he followed those steps as they are there and with that firmware, but for some reason it isn't working at all for him now, nor anyone else with this type of bricked tablet. I've tried it several different ways myself and no luck. It could be that we're just not doing it right, but I've followed the steps to a T. even did things like formatting the internal sdcard with the u-boot or even as just a large FAT32 partition, as suggested in other tutorials and comments in those tutorials. No dice. Right now I'm at work and doing the break down of my tablet. I'll take pics and inform everyone if I find anything useful.
P.S. Not to say it wouldn't work, because obviously it has already, so by no means should anyone be discouraged from trying to go that route and build a good U-boot. hell I'd like to see that so no one has to go through the soldering/serial hell that this may turn out to be, plus having multiple ways to recover our tablets from potential bricks, the better! That way we can develop more boldly without fear that we might trash our beloved tablets, knowing that there is some way to fix it even if everything goes tits up
Well this is what I've got. I don't know if I really did find anything useful on the back, would seem there is other pads for things, but nothing thats labeled like the herotab/dropad. anyways, I'll leave these here, sorry for the crappy quality as I only had my HTC Hero with me to take the pictures. hopefully some one with a little more hardware skill can make sense of them
Hmmm, many open pads in the back indeed, but no label. I wonder if Coby can help, and if they didn't cripple the SD recovery function...
The board for 1024 is quite different, besides the smdkv210 board.
Im testing a 1024 froyo with my 7024.
The stock 1024 firmware is great bluetooth is working. I was able to use my usb bluetooth dongle and pair with my cellphone. 3g is working and also hdmi.
Its also newer than the android 2.2 version of 7024.
Sent from my Coby Kyros 7024
If everything works, are you planning on modding it like the CFW 7024 you posted on the other thread?
That's cool that bluetooth is working.
Maybe using a gamepad (PS3, Wiimote, Xbox 360 controller) for emulators is now possible.
as mentioned in the http://www.androidtablets.net/forum...3007-project-reviving-hard-bricked-kyros.html thread, if anyone has a spare board/tablet they don't need or care about right now, I would like to get an extra one to see if can pull up a serial connection and if there is a SD boot option that can be had, like with the Herotab/dropad. Unfortunately, I don't have the money to buy an extra one and make my current bricked one my test board.
already posted the latest one for 7024
How did you get it? Pics? More info? Thanks.
So any news or ideas? seems the threads have kinda gone in active, though it would seem there is hope as Tileg has gotten a terminal connection before. I might try wiring some of the pads myself and see what comes of it, but really reluctant as I don't want to possibly damage it further.
Also, thanks to a good friend of mine, I found this little nugget Smartphone hacking without risk – plus, broken phones needed - Hack a Day its essentially a bootloader flasher, that is for the samsung captive, however, it seems it is possible to use with cortex-A8 processors ( The captive has the Hummingbird core, and from what I've read, so does the S5PV210. Maybe possible to use with little to no modification ). The thing you have to do is mod the OM5 to the OM1 just like with the Herotab/Dropad as described in some of the Slatedroid threads. the kicker here, is with that software they've developed, you can use the usb to flash boot loaders to nand, instead of the SDcard, making the tablet virtually unbrickable.
Also forgot to mention that it would work great also for loading bootloaders for running native OSes as well (linux,windows, etc)
My Kyros 7024 died. He does not care, just turn on the LEDs. Can anyone help me?
