Re: WD Charger strange behaviour

[pbzcbf...@gmail.com]

Have you tried the obvious, ie wiring up a USB connector to the USB traces?

If that doesn't work, you need to swap the MCU and ROM to another USB PCB and convert it to SATA.

What is the wires that is used for soldering to converting it to sata ?

Where does the SATA header come from ? 

[juan van der meulen]

You only need to solder up the USB2 section only x4 cables, plus power and ground.

Are there diagrams to show where to solder to points ? 

[RecuperoDati299]

it should be investigated the area

the board is a wafer with an amount of layers

and either if you power it up with USB2SATA modification, it is not said it would work properly

though, the first step is to locate some point where to connect the +5V

and listen to the drive.

If it spins up, then you can do the rest of the modification

otherwise it will be needed to move the Marvell controller on a donor board

stencils are available for the reballing process, but you need a real reaballing Guru and Pro, because the tin balls required for that chip are really small and close

Have tried the things below but cannot get drive to come ready so can MCU decrypt sectors.

• Donor ROM (locked or unlocked) on donor USB board spins up and ID's
• Patient ROM (locked or unlocked) on donor USB board spins up and ID's
• Donor ROM (locked or unlocked) on unlocked SATA PCB spins up and ID's
• Patient ROM (locked or unlocked) on unlocked SATA PCB spins up and ID's

Using donor USB PCB and patient ROM with pogo pin board, full ID, access etc, just MCU encrypted sectors. So pogo pin board doesn't seem to be problem.

Using unlocked SATA PCB with patient ROM >> 
Full SA access, mods backed up, some minor firmware changes and everything looks good... except MCU encrypted sectors (expected).

So try:
Patient ROM (locked or unlocked) on damaged patient PCB (with pogo pin adapter) no spin but status registers come ready DRD DSC

LDR and 02 via Upload dir into HDD RAM (copy 0 or 1)

Cache ovl(10) data uploading............ : Ok
Permanent ovl (11) data uploading....... : Ok 

<drive starts spinning and stays spinning DRD DSC>
Module 02 uploading..................... : Statc Mdl writing error Device Error Detected: "VSC ERR STATIC FILE INVALID"

Still cannot get SA access, ID or LBA etc.

Any ideas what can do here ?

How to find the points the solder four wires of a USB 2 cable ?  

Thank you

[RecuperoDati299]

What device do you have

Acelab?

DFL?

MRT?

Grab a similar PCB and connect a USB2 cable to it and then measure each pin connection from the cable end to the PCB and label each one, if that is done find another cable and cut the USB section off and solder cables back to the patient board according to your diagram and labels.

perfect

if you ask to Acelab support, despite you have an active contract or no, they will share with you the picture for the soldering points

(usually they do)

Thank you, will try these

[Desert Data Recovery]

I have never had to use a stencil for these. Hand tinning is enough if any pads need to be touched up.  The secret is to remove most of the solder from the heat sink area, as this can cause the chip not to sit straight.

I found some of these the lab but never had great result from them, better from pogo but I can try and use this to solder the points.

I think in the past time I had troubles making the wires stay connected to the pads.

Those wires looks like thick and rigid, use thin silicone wires.

May seem weird, but these work really well. Used them a lot before the pogo pin style boards came out.

They don't answer like that on these issues

just drop a ticket with the unique available option

and see their reply.

Ace will just tell to renew TS contract.

@ karpatis  

Do you have an example of better wiring type ?

@ Tim - Desert Data Recovery

they make it easy to know what point to soldering to and if SATA conversation does not work, then I am guessing MCU swap is a only way, unless try USB 2.0 and find the points for solders.

[RecuperoDati299]

unfold the wired cable of a smartphone earphone

you'll find nice "hair-like" copper wires painted with insulating colored transparent paint

that is perfect for the purpose

Connect the Reset* pin to ground. This will keep the bridge IC quiet.

hello Franc

this is a nice hint

do you mean instead of removing the capacitors?

@ Carmet L: 30AWG is your friend: https://www.aliexpress.com/item/1005006250522147.html

BTW I use this green PCB adapter board: https://www.aliexpress.com/i/1005004235591426.html

Bottlenecks: the switches have contact issues, the VRMs (on the other side) are weak by default, so I replaced them with two TLV62569. Potentiometers also built in to fine tune their output voltages.

Decoupling capacitors (4x 10nF) must be soldered if a SATA drive is in use (either wired or connected).

[pbzcbf...@gmail.com]

You don't need to remove anything. If the bridge is in a reset state, normally the I/O pins will become high impedance (high-Z). That's typical for MCUs.

[juanvd...@gmail.com]

The red dots are the USB2 data lines, just solder x4 thin wires of a USB cable that correspond to those small caps remember the caps must stay in line so solder the wires on the connector side not IC side. Then the red cross is the 5v connection and ground you can figure out close to the usb connector.
