Importantly, it also has the ability to repartition the device storage based on a .pit file, which can save you from softbricking (when flashing goes wrong and recovery/the bootloader fail). It is not open source and to my knowledge they have not intentionally released it — a few versions have been leaked. For what it's worth, I have used the version posted here without issue. Heimdall, however, is open source and duplicates the functionality of Odin. It claims to be more reliable as well, in addition to being cross-platform (Odin is Windows-only). Both tools appear to work best with Galaxy S devices, so if you're using another device you probably want to ensure someone else has tried it and succeeded. Another note is that they use .tar packages layed out differently than the normal update.zip format used by recovery and OTAs, so you need to get the proper package for it to work. === heimdall === Then turn off your phone, enter Download mode, connect the USB to phone. Next I used command like this to do the flashing itself sudo heimdall flash --MDM modem.bin --verbose --no-reboot Also to you can use to diagnose more with these, in case of issues <pre> heimdall --version sudo heimdall detect sudo heimdall download-pit --output I9505.pit --verbose --no-reboot </pre> <br><br> == 基带固件 == 原生系统基带版本:T959UVKB1 <br><br> <br><br> <br><br> <br><br> <br><br> <br><br> <br><br> <br><br> <br><br> <br><br> <br><br> <br><br> <br><br>
