    Swap nand flash smartphone for data recovery
    by DoOm86
    Hello everyone.
    I would like to know more about the following topic:
    Nand flash on smartphone for data recovery.

    I have been reading of people swapping nand flash from a faulty mainboard to another in order to save the data.
    But I also read about encrypted data which to be read must been swap also cpu, or nfc or something else where is located the key to make the data being readable.
    How does it works? How do I know if data are encrypted or where is the key?

    I know there are also very expensive external socket where you can put the nand flash in...

    [Help] Lenovo Yoga Slim 7-14ARE05 (DA0LS3MBAF0) – 25Q80DVN1G Flash Is All FF, USB-C PD Stuck at 5V
    by ekozeko333
    Hi all,
    I’m trying to recover a Lenovo Yoga Slim 7-14ARE05 with board DA0LS3MBAF0 Rev:F. I’ve run into an unusual issue where USB-C PD is stuck at 4.7–5V and the system won’t boot (keyboard lights flash briefly, then nothing).
    🔥 The Problem Started After Suspected ESD/PD Fault
    I experienced a power issue or ESD event through a USB-C charger
    After that, the NX20P5090 power switch was visibly burned and was replaced
    Now the PD controller always negotiates 5V @ 2A, even with known-good chargers
    🧠 What I’ve Done So Far

    JVC LT-32VF52K - Boot Loop - Nand Flash Steps
    by mijatovic86
    Hi everyone,

    I have an issue with JVC LT-32VF52K, that is chassis Vestel 17MB110.

    It just flashes Logo JVC and then red led flashes for 12-13 times.

    Tried with flashing SPI MX25L1606 but acts identically with it also.

    How can I try and flash the NAND using only USB ?

    Can it be done with USB flash drive and usb_auto_update_A1.txt file, and what should be the content of that file ?

    I did find a nand dump on elektroda.pl, just need to be sure how to flash it ? Its LED JVC LT-32VF52K_NAND.BIN around 540MB large

    iPhone XS Data recovery from NAND flash
    by Spider1211
    Hey guys, I have an iPhone XS which came in as dead. The phone was not worked on before (I was the first to open it). After diagnosis (Splitting board, etc) it's confirmed to have a shorted PP2v63_NAND line.

    Removed the NAND flash and short is gone on the board. Measuring directly on the NAND, there is about 2 to 15ohm to ground.

    Is there anyway of backing up data externally in such cases (Client has some very important files and no back ups)?
