Sp flash tool readback preloader
But apparently the error did not occur directly after flashing the partition which reset the bootloader. When I ticked *all* partitions in SP flash tool, I got "verified boot is enabled" at some point during the flashing (Download) process, so apparently one partition re-enabled secure boot (locked bootloader). When I tried to find information on this, I either found documents that were very vague, or that made no sense without appropriate background knowledge. I need to say that I figured this out by trial and error. But maybe the data will be incompatible for other reasons.) I'm going to try that now, before resetting. Maybe I should try to read back the reserved partitions by putting in the numbers.

I didn't check the android developer documentation on that so this is just a guess, but if that partition is used as a one-time-pad for encrypting userdata and it is reset while unlocking the bootloader, there's not a chance in hell you could use the encrypted userdata.img dumped with the previous OTP. OTP refers to "One Time Pad" in cryptographic terms. (Final thought: There's a reserved partition called OTP, which apparently cannot be read back with SP flash tool. I'll see if I can recover the userdata.img afterwards, but I doubt it which is why I just updated all the app backups I could round up.

I now have the full readback of the cosmo, done with SP Flash tool and I'm going to just root it. I've come across some other tools to analyze the partial dumps via google, but didn't really take a closer look, because SP Flash Tool only works on windows for me, and for CLI/programming stuff I strongly prefer Linux. However, WwR has proved invaluable to get that scatter file. I think mine is correct (Edit: Spoiler: I was wrong about this!), because when I have SP Flash Tool (latest version) connected to the Cosmo, it gives:Īctually that last number is the coveted size for the full EMMS_USER dump with WwR, so it appears there are easier ways if you just want to get just that number than running WwR. Surprisingly I have found a difference between the two, which may be significant: As promised, I have compared your scatterfile with the one I got from analyzing the EMMC_BOOT_1 and EMMS_USER areas with WwR.
