Hi, yesterday my Switch OLED wont turn on. The HWfly LED pulses purple, and then solid red. So i've desoldered the emmc point on the chip, and soldered again. Now the console starts without problem. But this is my second time that this happens. The console wont start like this, always when i leave the console charging too long (like 24h+). Any ideas?
Maybe the culprit in not your wire, could be your dat0 adapter...
I don't like too much the one that comes with the oled v4, the single anchor point one, I prefer the double anchored one. Also check for rests of uncleaned flux that can give to you false contacts in the MMC dat0 point.
Hope it helps
Good luck!!!!

lol I had this exact same problem and the store where I asked them to do the chip installation said they couldn't fix it and offered me to buy new one at discounted price ($150).

Hi, guys. I'm having issue on my switch lite! I'm getting the boot loop while the led is flashing purple then boot to OFW when the LED turns red. Here is the video of what happened:-

Please help!! 🙏 😭😭
Just an update on what's happening now. My switch is running perfectly now, able to boot into hekate and CFW.

I de-soldered everything and re-solder again, but when I de-solder I accidentally pulled out the SP1 and SP2 capacitors 🤦‍♂️🤦‍♂️ then I tried to solder the chip on the board directly without the SP1 and SP2 caps and it works perfectly!

Will it be any problem in the long run?

Look for the videos sthetix did. He has a couple on flashing via USB or directly using a flash programmer if needed. It is possible to break the USB functionality if you plug the USB ribbon in upsidedown or if flashing doesn't work and you don't switch to another USB port before trying again.

i saw all videos of sthetix and only shows how to flash or unbrick hwfly core 6 no 7.1, he say when you connect hwfly to pc and you have a red light you have to use a st-link usb, soldering 4 points of welding to hwfly v6 and connect to pc but only to hwfly v6,not hwfly 7.1 i think its another points of welding but i cant find it what points of welding are in 7.1?, it is assume 7.1 can update or flash by usb but when i connect to pc but only blink in blue light and pc dont recognize. Ok my questions are
Is there a driver for pc that recognize hwfly core 7.1 by usb? if not

I would not say it is "possible". It is a CERTAINTY and it is INSTANT (if you plug in the usb cable to both the computer and adapter, while it's upside down).

The thing about the debug port that caused confusion is that the original sx core has the opposite orientation to the mv1.7-1 chips
