Extract Bootloader and Ubootenv ?

[niabi]

is there a way to extract the Uboot (bootloader) and UbootEnv to flash on another device? by mistake I flashed a wrong uboot on one of my devices :/ and now Wifi/Bluetooth does not work. I have another device (same brand and model) and I was wondering if there is a way using ADB that I could extract the bootloader and ubootenv to flash it on the one that is not working.

any ideas? tips?

Thanks

Maybe you should also give an information which device you talk about... maybe there exist a fw you can flash instead of extracting something...

its a gamestick, which is basically the same as the Geniatech/MyGica ATV120 but the problem is, I used the SPI from the ATV120 and now the gamestick is dead, no led no nothing, so have to find an original SPI/UBoot to try and recover.

OK, it's an Amlogic 8726 mx?
Do you have the original fw (link)?
Do you have a working device and does it have an OTG?
BTW: how do you think to flash the correct uboot(env) if the device didn't boot up? Via "special' SD?

Thanks for the reply.

its a 8726-MXS and Yes, I have the original FW, but it does not include a uboot nor recovery. thats why I am trying to get it out of another device.

I've read several posts on how to do this, with the special SD, but without the correct recovery, u-boot it won't work.

I also soldered up the SR232 connection and I can see Android trying to boot, so I am sure the stick is not completeley dead, just need a way to flash the uboot/recovery since I cannot interact with it :/

anyone have experience with the SR323 on one of these devices?

here is a photo of a ATV120 (very similar to the gamestick) that shows the SR323 connections (those 4 cooper circles of course) http://i.imgur.com/vR51z.jpg

Just bought a Gamestick also, so I am very interested if you get your back up and running. I love the Gamestick, but the software is meh. They have basically stripped alot of Android functionality away from it. I am sure they have there reasons, but with the limited amount of gaming they have really cut down on what consumer will purchase it. I have posted two threads in there development thread and asked for the source code of there ROM, and/or a Factory Image and their means of flashing a factory image back on there. I am curious how you flashed that other Android stick software on thier to soft brick your Gamestick what method did you use? Or is that not what you did. I imagine you used fastboot or ADB. Maybe they will answer me back and then you can try to flash yours back to factory. Anyways I wish you luck and hope you get it back running.

If you have a working device you can dump the recovery...
Run

cat [B]/proc/mtd[/B]
cat [B]/proc/partitions[/B]
ls -al[B] /dev/block/mtd/by-name[/B]

in terminal and see what you get...
To dump you have to use this

dd[B] if=/dev/block/mtdblock[I]XYZ[/I] of=/mnt/external_sd/recover.img[/B]

and an SD card...

I hope you can use this recovery dump at "special" SD card...


Maybe you also find the uboot with this way, but I don't think so at the MX...???

no need, all their FW is garbage, it only has the store. even the developer version is garbage.

I made my own, just unpack an ATV120 FW, and replace the boot.img (from the original gamestick FW).
BT and wifi worked great and even the gamepad was usable, all the games I tried run perfect.

so really there is no use for their FW.


but DO NOT flash the uboot or recovery, you will end up like me.

I have to run right now, but I will explain the full details later, just so you understand, the ROM i made worked perfectly, my problem was that I mistakenly put another SD card, with the rom from another device (ATV120) which overwrote the uboot/recovery making it a hard(deep) brick, no softbrick.

if you only flash a regular ATV120 rom, with the boot.img (not uboot.img) from the gamestick, it works with no problem

use the button on the side of the USB connector (have to press down, not push inwards) while you connect it to the power and it should give you the recovery console.

if you don't know how to do that, I will explain in a few hours.

Thanks a bunches,


I basically told them on there dev site there FW was crap lol. The have all the goods things disabled and to not even have the controller set up to have the right analog stick to act as a mouse like on the Nvidia Shield is inexcusable. What recovery did you use to flash that AV120 rom?

[niabi]

ok this is how I did it :

using 7-zip open the ATV120 firmware (latest is update_stvmx_20130805_eng_dongle) and delete boot.img, then using 7-zip, open the Gamestick firmware, and extract the boot.img, add this file to the ATV120 FW, you will need Sign-em! 2.0 (http://forum.xda-developers.com/show....php?t=1966007

) to sign your new firmware.be very careful, after you flash the FW you will probably get an update from geniatech, DO NOT apply this update, it will ruin your Wifi and you won't be able to recover, unless we get the SPI/Uboot from Gamestick, which I doubt we will, I already ask and no reply whatsoever.


BTW the controller has 3 modes, mode 3 is mouse emulation

Press the back button until the 4 leds turn on, then while pressing it, press start until the 3rd led is selected, let go and now the gamepad is in mouse mode.

their "manual" is REALLY simple and bad, I am disappointed in the gamestick to be honest, same HW as a Chinese stick, virtually NO instructions, and the gamepad is really bad.

I basically did all that you just listed but for some reason I get the android about halfway thru it aborts the installation but does not give an error, it gives the magic 7f45 so IDK. I am using a usb flash drive, should I be using a sd card instead?
