SharpEDL 1.0.5

SharpEDL

Introduce

Warning: This project is experimental supported, more test needed

SharpEDL is a native implementation of Qucalcomm EDL communication using C#
.NET Runtime version 8.0, tested on my device(Redmi 5 plus)
Already implemented:

• Get device info and send programmer under Sahara mode
• Read/Write/Erase partitions
• Sparse file flash
• Parse partition table
• Flash flat build, generate rawprogram files
• Mi device auth/noauth

Get Started

Sahara read device info

SaharaServer server = new SaharaServer { Port = port };
server.DoHelloHandshake(SaharaMode.Command);
string msmid = server.GetMsmHWID();
string pkhash = server.GetOEMPkHash();
int serial = server.GetSerialNum();
int sblVersion = server.GetSblVersion();
Console.WriteLine($"MSM HWID:     {msmid}\n" +
                  $"OEM PK Hash:  {pkhash}\n" +
                  $"SerialNum:    {serial}\n" +
                  $"SBL Version:  {sblVersion}");

Sahara send programmer

SaharaServer server = new SaharaServer { Port = port };
// Now at Command mode, let's switch
server.SwitchMode(SaharaMode.ImageTxPending);
var state = server.DoHelloHandshake(SaharaMode.ImageTxPending);
FileStream stream = new FileStream("I:\\tmp\\qc\\mi_noauth_625.mbn", FileMode.Open, FileAccess.Read);
server.SendProgrammer(state.ImageTransfer, stream, (uint)stream.Length);

Readback image

FirehoseServer Server = new FirehoseServer { Port = port };
Server.ProgressChanged += OnProgressChanged; //optional
Server.ReadbackImage(new PartitionInfo
{
    Label = "boot",
    FileSectorOffset = 0,
    StartSector = "790528",
    SectorLen = 131072,
    BytesPerSector = Server.SectorSize,
    Sparse = false,
    Lun = 0,
    FilePath = "I:\\tmp\\qc\\boot.img"
});

Write sparse partition

FirehoseServer Server = new FirehoseServer { Port = port };
Server.ProgressChanged += OnProgressChanged; //optional
PartitionInfo info = new PartitionInfo
{
    Label = "system",
    FileSectorOffset = 0,
    StartSector = "1054720",
    SectorLen = 6291456,
    BytesPerSector = Server.SectorSize,
    Sparse = true,
    Lun = 0,
    FilePath = "I:\\tmp\\qc\\system.img"
};
Server.WriteSparseImage(info);

Write unsparse partition

FirehoseServer Server = new FirehoseServer { Port = port };
Server.ProgressChanged += OnProgressChanged; //optional
Server.WriteUnsparseImage(new PartitionInfo
{
    Label = "boot",
    FileSectorOffset = 0,
    StartSector = "790528",
    SectorLen = 131072,
    BytesPerSector = Server.SectorSize,
    Sparse = false,
    Lun = 0,
    FilePath = "I:\\tmp\\qc\\boot.img"
});
