1-Desolder the FT3 chip
2-Was able to read the MX29LV800CB or MX29LV800CTTC and programmed with u-boot-nand.bin
3-Soldered the programmed MX29LV800CTTC back to the broken Pad, reboots with screen test...
4-Now you should put the tablet in flash mode, to use IUW (or burntools)...
5-Connect the tablet with the usb cable to the PC
6-Press and hold menu + power.
Tools:
- Sholdering iron;
- Willem programmer with a TSOP48 (8/16bit) adapter
Tips:
- Do not use hot air ... processor is too close to epromm!!! (If you do not want to do reflow after)
- Use flux and solder on all pins on one side and gently lift the eprom ...
- Pay attention to short-circuits...
I tried two epromm MX29LV800CB (programmed with u-boot-nand.bin flytouch 2) and MX29LV800CTTC
(programmed with u-boot-nand.bin flytouch 3). Both have worked for me ...

wow, that is a big job
I have exactly the same issue after loading "wrong" file through usb
Menu+Power does not get me connecetion to PC any longer
problem: u-boot-nand
A few questions:
1)Is it possible to leave chip on board and connect programmer there?
2)Do you have a pin out of the chip, I have MX29LV400BTC
3)How did you connected to programmer ? soldered ? how many pins needed to connect?
4)Which program did you use to access chip ?
Thanks!

1. No. Chip must be removed
2. Google MX29LV400BTC.pdf
3. I made an adapter (TSOP48 - 8 / 16 bit) for Willem programmer. Yes. Almost all pins.
4. Software Willem 0.98D11

I did a little mistake that will need such approach... but how did you manage to find a correct file to flash the MX29LV400BTC ?

I have not found the correct firmware. I tried several versions. All worked. That's why I stuck with 1G tablet. You can update via USB.

From what i can see in this files, your dump is from an already updated u-boot-nand.bin LV800 with 0.6.1.2_1.4.587_OV2655 version.
Correct me if I'm wrong.
So, perhaps, if you had the binary dumped from an "old", not yet updated, LV800, your problem will be solved. Perhaps the 0.6.1.2_1.4.587_OV2655 "Bios" is not compatible with you hardware revision...

Hello, I know that this post is the old one, but I hope that you can help me. ;o) I'm looking for a binary file (or files) to programme flash MX26LV400BTC-55 in my ePAD/infoMATIC 10``tablet. Could you help me, please??? Or tell where I can find this bin...
