Okay so I thought I'd take the liberty into looking somewhere to help port a few ROMS and all! I wanted to start off with Blisspop, since it's personally my favorite aside from CM due to vast USER customization features! Mind you, I'm not exactly a developer, I mess with basic codes and do stupid random things in windows batch files and stuff, but I'm not entirely familiar with the linux system. It all seemed a bit complicated, which it really is! Anywho I used this tool to help me! I got a few errors, but I eventually figured out it was because the base ROM, Our CM12.1 ROM, used a "system.new.dat" a compressed archive in which the tool wouldn't extract. So I downloaded an extractor tool and was able to extract and copy the files to the system of the base ROM! I used a Blisspop 4.1 Running Android 5.1.1 For the LG Volt (LS770) I started the compiler batch script and after about 5 minutes, and a few build.prop edits that were prompted, I got a BlisspopROM.zip in the output! I thought "Cool!" and transferred it to my SD card to flash onto my LG Stylo; originally MetroPCS, but has Tmobile firmware flashed over. I reboot to TWRP, do a factory reset, and then proceed to install the zip file, only to get an error ------ Installing 'FilePath/BlahBlah'... Checking for MD5 file... Skipping MD5 check: no MD5 file found E: Error executing updater binary in zip 'filepath' Error flashing zip 'filepath' Updating partition details... ...done ------ After I got this error I started to mess around and see if I could fix it with the basics. I tried opening up the updater-binary in Notepad++, but it only shows a bunch of jibberish and very few understandable variables and a few functions I believe Could someone shed some light on what I might be doing wrong? I've made an assumption and just thought it was because the original updater binary (BASE CM12.1 ROM) was for installing "system.new.dat" and not directly copying the files over. Since the blisspop ROM I used as my port didn't use the .dat compress archive, it had everything in "Blisspop.zip/system"; where you could find all the system files (Apps, framework, etc, etc) The CM12.1 ROM that I used only had build.prop in the system. Is there a way to bypass this error? or fix it? If you need the PORTED ROM then please send me a private message and I will link you to the "BlisspopPort.zip" in my gdrive! Thanks in advance!
