Please help.
My Switch stucked at Nintendo Switch logo screen after thermal paste change...I can load reinx with tegrarcm so the sdcard working, but after reinx logo, its stucked at Switch logo...
Any tips,help? Thanks..
OK... First of all, don`t panic.
Second... What paste are you using? Forgive me if its mentioned, I`m only skimming through.
If it is silver based, it can cause capacitance, which has potential to upset processor timings. Just as a test (don`t worry - it won`t burst into flames) - remove all paste from die i you removed the copper speader
I`m wondering if you removed the copper pad. It acts as a heat spreader. When the console is new... After a while, the stuff under it starts going crusty until it turns into plasticine.
You can remove the heat spreader - use some completely inert compound. You need to remove the ram shield temporarily while cleaning... The compound - Ceramic stuff I use. It is better than OEM. In my thermocouple tests, temperatures were lower. People replace the compound without giving a thought to the stuff that has turned to play-doh under the copper spreader. Pointless having good paste if you still have a layer of shit between that and the die...
But if removing the spreader, you NEED good, non-capacitive paste. Then once the die is spotless, apply.
If you have left the copper sheet intact, it cannot be a capacitance issue.
Can you check your BTB connectors are fastened correctly? The gamecart one is possible to get misaligned and it fooks the pins.
Also... Anything you have disconnected - ie emmc / joycon ribbons / backlight - make sure no old or new compound has got in the connectors. The BTB connectors ie emmc are super fragile, as is the sd card... Remove SD reader and retest. With a bent pin, that could cause problems with the emmc voltage as they run on the same 1.8v buck reg if mem serves correct (can check).
Good luck sir
