Steps

The fault

1. It is located at the level of the Tegra X1 chips which offer the possibility of modifying the "Boot Rom" and installing Custom Firmware (CFW), i.e. a modified boot menu
2. /!\ This flaw being hardware, Nintendo had to release another version without any real change apart from a patch

eFuse

1. These are nano fuses integrated into the Tegra chip (NVIDIA) which equips the Nintendo Switch
2. These fuses blow (or burn) after a firmware update, it is an anti-downgrade device
3. The Nintendo Switch has 32 eFuses
4. Firmware 17.0.0 = 19 eFuses

Find a Switch v1 Unpatched

1. On LeBonCoin, Facebook Marketplace, or other
2. /!\ No Erista Patched (v1 Patched), nor Mariko (v2, Lite, OLED), otherwise the RCM will not be able to work, since the hardware flaw is corrected

Chip

1. If RCM is not possible, the only solution is to solder the "SX Core" chip for between 50 and 150 € (+ 100 € labor, if you can find someone who can do it)
2. /!\ The SX team having been arrested, the latter's stock was exhausted and the price had soared

Chip (copies)

1. > There are copies (almost identical) like HWfly
2. More recent ones not as well finished like PicoFly based on an RP2040, which still shook up the market and forced HWfly to make an update
3. /!\ Prices have therefore dropped to 10 € (+ 100 € of labor, if you can find someone who does it)
4. You still have to be careful, because many sell only one of the parts and not the whole

Price order (if the person DOES NOT KNOW that it's an Unpatched v1)

1. > Approximately between €150 alone up to €200 (if presence of accessories, games, protections, general condition, etc.)

Price order (if the person KNOWS it's v1 Unpatched)

1. > Approximately between €250 alone up to €300 (if presence of accessories, games, protections, general condition, etc.)
2. /!\ If the price is lower, this is generally to attract and will refuse the displayed price, either scam or problem

State

1. There will probably be some traces and marks, but no problem because the goal is to play on the TV
2. /!\ Don't forget that it's second-hand
3. > In addition the v1s date from 2018

Joycon drift

1. Nintendo officially recognized this problem on v1, namely that the cursor moves as if the joystick was stuck, when it is not
2. They put in a replacement solution, long and not always functional, the simplest thing is to change them for new ones
3. A solution may be to put WD40, this has no impact on the rest of the console

Switch Serial Number Checker (SSNC)

1. > Ask for the serial number under the console to verify that the console is an Unpatched v1 (with the serial number)
2. https://damota.me/ssnc/checker/
3. /!\ Preferred the serial number in the settings than the one under the console (normally the same, if the seller does not try to see have)

1. Switch RCM Loader (Loader + Charging cable + Jig) [around €15]
2. https://fr.aliexpress.com/item/1005006304452523.html
3. > Buy the kit to start it in CFW mode (see a second one for safety)

8. /!\ Buy a minimum of 128 GB (a few games), 256 GB (backup + a few games), but strongly recommended 512 GB (huge difference, backup + lots of games), or more depending on your budget and promotions
9. > If you take the 512 GB or more, the Extrem version will be better, because the difference with the Extrem PRO is not significant
