Possible Alternative Method to Recover from Corrupt Bootloader.

[Maverick.Ita]

Here is an elaborate explanation for those who want to try this:

Requirement: USB Male - Male Cable.

Boot Card Maker - from chinagadgetsreviews (I can't post links apparently)

AMLogic Customization Tool - It's here on the forum, in the tools section I believe.

Get a firmware package for your device - Mini M8S II - Here: chinagadgetsreviews - rv112 version
And also grab the USB Burning Tool from the same page.

Now you're prepared.

Unpack Your firmware with the Customization Tool (Just open the software, click "Load" just select one option like modify dtb or whatever).
Now open the folder where you installed Amlogic Tools - C:\Program Files (x86)\Amlogic\CustomizationTool - or wherever you put it.
Here you'll find a directory - tmp - go inside, then to directory - level1.

Copy the files: recovery.PARTITION and bootloader.PARTITION and meson1.dtb

Copy these files somewhere safe In this safe place, rename the recovery / bootloader.PARTITION files to - recovery.img and u-boot.bin respectively. Then rename the last file to dtb.img.

Open bootcardmaker. Select the u-boot.bin file and burn it to a small sdcard, following the onscreen instructions. After that put all the files you copied and renamed (including u-boot.bin) on the prepared sdcard.
Now you can put that card in your tv-box.

But we're not done yet, so don't turn it on just yet. Now, open the USB Burning Tool, select the stock firmware you downloaded (or maybe some other ROM you wanna flash).

Now, with the sdcard in the box, and the USB cable ready - put one end in your PC and while doing the "toothpick" thing. plug it in you tv-box. It should be recognized by the Burn Tool on you PC now.
If you try to flash right away you might get an error, this seems to be because it needs more power - so plug in the power adapter also.

Now flash and you should be fine

Hi Stenor

This procedure is also valid for amlogic 912?

Hi gefattern

Ok I try

[hectorcrk]

hello to all user , in my firmware file not found a " meson1.dtb " how to solve it, thanks

[soldiaz]

Well I guess this is last way for me to unbrick.....hope it will solve issue!

It should work, if not a reset of the Nand chip can help.

How can I reset?

I managed to get box connected and shown in Burning tool.

It starts but then quits with this:

[15:17:56 916][Global][Inf]--Update HUB3-7
[15:17:56 916][HUB3-7][Inf]--Update device path
[15:17:56 916][Global][Inf]--Update HUB3-8

Open up the box and look for the Nand chip.
If you are not sure what is it make an photo from the PCB of your Device.
On the Nand Chip we have to short pin 5&6.

I appreciate your help!

I marked left side and made a bar beside the pins I previous shorted to make AMLOGIC BURNING TOOL can connect

[neomode]

The Chip with BYA over the S912 Label should be the Nand chip.
Connect the Device with USB cable to the PC and use a paperclip to short the pins. Just going over all pins on both sides.
Then press start to burn the Image.

[soldiaz]

What about power ? Only USB'?

[soldiaz]

not recognized..guess need power supply and usb power

[neomode]

Yes possible.

[soldiaz]

Ok plugged all in, loadedmrom, pressed start. Then going over pins. suddenly it starts, but same result...quits after 2 percent
