📌 NAND chip installation
- Remove all original NAND chips .
- Turn on and check the voltages:
- PP1V8_SSD0 AND PP1V8_SSD1 = 1.8V
- PP0V9_SSD0 AND PP0V9_SSD1 = 0.9V
- PP2V5_NAND_SSD0 AND PP2V5_NAND_SSD1 = 2.5V
- If the voltages are correct, install the new NANDs in the order indicated on the chips: U8600, U8700, U8800, ...
👉 Respecting the order of the chips is crucial to avoid system errors.
