[Pico 2040 from Ali] Cannot boot OFW from eMMC, emuNAND works fine
Hello,
I have installed a Pico 2040 on my V1 patched Switch yesterday. It's an "easy install" hwfly pico clone with the CPU flex cable.
I copied my sysNAND to the SD card and I've had a warning saying that there may be memory issues wih the eMMC. I booted emuNAND from SD card and it works fine.
My issue is that I cannot boot Original firmware from eMMC chip. I tried the "Reboot to OFW" option in Hekate and I also tried to boot holding vol+, vol-, clicking power and releasing volume buttons once Nintendo logo appears. The screen is always stuck on the "Nintendo SWITCH" logo.
I tried to boot holding the RESET button of the modchip while booting but I've had the same results. So I guess I can deduce it is not a firmware issue. To troubleshoot the issue, I disconnected the modchip to connect the eMMC chip directly to the console and the original system firmawre does boot ! I guess I can deduce I did not cause any damage during installation.
I sent a message to the seller, maybe they can send me a new chip. Did anyone have a similar experience and was able to resolve it ?
Here's a picture during the installation. I have put Kapton tape on the CPU capacitors and around the modchip after I've taken the picture.
Thank you
Have you tried updating the modchip to latest 2.75 FW from rehius just to make sure the modchip FW is not corrupt?
You can find the firmware repo here: https://github.com/rehius/usk/releases/tag/PicoFly_2.75_2023.09.09_08-16
Well the seller sent me firmware 2.65 to flash (I have 2.74) but I could not flash it, after I drag the file, the chip disconnects and reconnects to the PC… And now my eMMC is even more corrupt (purple screen when trying to boot OFW). User data partition was deleted for some reason so I did a NAND restore. OFW is now stuck at logo again. EmuNAND still works. Still really bad experience overall. I ordered another modchip from Amazon this time. Let’s see if it fixes the issue… Now I really wish I left my Switch alone from the beginning.
Just to add clarification for everyone, the chip you get off of Amazon will be the same quality as alliexpress, it will just arrive faster. Also don't sweat it, it still works so I'm sure you'll get it figured out.
Do note 2.74 is the unstable fw with 300mhz clock. I would recommend not using it.
I installed a new chip ordered from Amazon today, it fixed the issue ! OFW now boots fine from eMMC. What a relief !
