Hacking After failed Oled modding

[Ahmedespo]

After installing Instinct NX v6 my oled won't turn on giving me just a black screen. I removed all the wires and the mod chip it gives me a white screen with longtudinal black line moving from left to right .

check to make sure you don't have any bridged connections, make sure you reflow the nand/eemc chip with flux to ensure no solder balls are joined together as well.

Please post some pictures of your mainboard

I double checked there is no bridged connections . And used dat0 adapter without reflowing . I didn't touch namd/eemc chip .

You didn't heat the chip at all? You just stuck the DAT0 against it and hoped for the best?

I stuck the dat0 and soldered the anchor points to the frame then measured the value and gave me 0.771

doing the dat0 that way could have shorted out your nand chip. its supposed to be reflowed/soldered to the nand chip

yeah you're suppose to make it flow then put in the ankor, make sure it sits then solder down the points.

I'm not sure what dat0 does, so I can't say if it killed the Switch or not.

I've had dat0 adapters that came loose, or came into contact with two BGA points below before (diode readings confirm value over 1) and it didn't do that to the screen. I would just first check that your OLED screen ribbon cable is seated correctly in to the fpc connector and that the fpc connector does not have any bent pins.

Thanks all for your support

What is fpc connector

What is fpc connector

The connector that sits on the mainboard that connects for the oled ribbon cable.

What is fpc connector

the connector for the lcd
basically check if any pins are bent in it

its a very fragile connector

also as long as you secure dat0 correctly , solder mask helps its secure enough, sure you can reflow it to dat0 but that brings about some bigger risks in itself and at that point you may aswell reball nand and run a wire.

hell the dat0 connector was literally originally designed to just touch it and just be anchored , i would know sense i was the guy who tested if flex cables could fit under the nand flash for the guy before he made the original mockups that china copied

I think if the ribbon cable or the connector causing the problem if I docked it will work normally . I docked mine the led light on the dock flashes rapidly once then nothing.

And according to dat0 I am pretty sure that I secured it very well with solder mask and it gave me the correct reading . Afterwards I opened it it ran into the official firmware not NX . Then I cleaned the board with dry PCB cleaner then rechecked the joints with my iron . Then when I turned it on once again it gave me the black screen . I removed everything and tried again it gave me the pics I showed you . I docked it to make sure that the problem is not with my ribbon or the connector and the same error

Thank you very much . Your help is appreciated.

Interesting seeing the issues that can occur with the OLED Mod.
Did you resolve the issue?

intersting install dat0 without reflow

Why is everyone surprised by this? The initial OLED mods all used this method. Slide the adapter under the chip, anchor it in place and run it. Mine is still working in exactly this manner over a year later as I'm sure many others are. Sure there are risks, there are also risks of attempting to reflow or reball. In either case, I don't believe that is the OP's problem. I'd look closely at the CLK and CMD points.

intersting you got nice hardware and nice luck
