[HOW TO RECOVER] So you bricked your box

[corno77]

Dear all,

I have connected my H96 Pro Plus S912 with 3GB DDR3 and 32BG ROM, to the serial port, and I receive this info in loop,a nd the cycle ends at "DDR init failed..."
This mean that the DDR chip is burned???

that's why I was looking. well thank you. only today I found this video where he writes how it can be used in my case https://youtu.be/-OtFvnZ24KU

can this be for a serial console connection?

Yes, and you have to buy USB to TTL/UART Converter ( Serial-Converter) and not device (EEPROM Programmer) from your post above.

can this be for a serial console connection? Q5x3_141 v3.1 19351 board

I bought this a long time ago ... could it be used for what I would like to connect the box via the serial port and look at the boot box?

[navo]

hello, i have x96max 4/64 neither lights up nor the power supply of usb readers or optical port. does it still make sense to come to life? thank you very much, I would also try to connect via a serial console but I'm afraid I would need more advice there. Thank you very much

Hi Calc: bootcardmaker only takes bin file, what do you mean by aml_sdc_burn.UBOOT???

[ph086]

If your box is really bricked then if you connect via serial console to it you will only see the following looping:

Hi calc.

So i follower your steps and was able to flash my box but im still stuck on the logo screen

Thanks, I can recover my dead h96max x2 by refering to this thread.

My h96max x2 is android 9, s905x2 and 4G LPDDR3 ( g12a_u212_4g, not u211 device) .

With the firmware from " https://forum.xda-developers.com/and...b-4gb-t4003395 ",

mine has dead loop on BL2 stage , DDR init process.
It is not possible to use usb burning tool method.

serial console says when failed :

LPDDR3 probe

Load ddrfw from eMMC, src: 0x000101ff, des: 0xfffd0000, size: 0xffffff, part: 0

I can bypass eMMC boot process and recovered from sdcard.

serial console says:

Hi.
i have this mesage from uart
GXL:BL1:9ac50e:bb16dc;FEAT:BDFC31BC:0;POC:3;RCY:0; EMMC:0;READ:0;CHK:A7;READ:0;CHK:A7;READ:0;CHK:A7;S D:800;USB:8;

LOOP:3.........

i see that is BL1 - This is the Boot Loader stage 1 is not on the eMMC.

i can't boot from sd card at all
i have problem with this

Step 2:

Windows
Use Amlogic Bootcard Maker to write aml_sdc_burn.UBOOT to the sdcard.

Bootcard Maker only worl with .bin files extension...
i make boot sd card with Burn Card maker and various roms...
I had no success

still same message from uart and no signal from HDMI..

What do you recommend

[MrJCub]

If you know a little about electronics, the larger ceramic capacitors will have a voltage for the output section. You should see 0.95v, 1.2v, 1.5v, 1.9v, 3.3v, and 5.0v at various locations on front and back sides of the main board.

If missing any of the above voltages, you will have a hardware fault. Most likely 3.3v may be missing in a critical location to drive SD card bus, and USB hub with the port for flashing.

You can test USB port voltagd by reading 5v voltage at pin 1, or installing a USB SD card reader with LED, it should light up when box has power.

Some boxes have two sections for 5v power sources. One is shared by power plug and the other has its own driving circuit to enable critical sections. So testing all USB ports is needed to verify that 5v circuits are functioning.

I did some testing last night.
Had 3.3v at the serial connection, 1.2v at various points, but couldn't really figure out where I should be checking.
The USB seemed to be missing 5v, so I added a power supply to that, but the boot log showed exactly the same...

[MrJCub]

There is a main 5v circuit that drives 3.3v, and other voltages. I discover on one box that the power plug only powered half of the circuit, and was able to add a 2A charger connection to the side that did not have the 5v power circuit active. Thus able to power the sub voltage circuits to allow boot. I had 4 USB ports, so once I added the charger to one of the dead USB connections along with the power plug installed the board was able to flash, and boot.

Great, thanks for the extra information!

[X92-2GB]

Thanks X92-2GB,
I'll do some testing and report back.
Wondering if testing that there was power at the serial connection would indicate anything. I assume there should be 3.3v feeding there.
I did notice that sometimes when I disconnected the main power that the blue led would stay on, being powered by the usb of the computer, but I guess that doesn't indicate if 5v circuit is actually working.
