Shorting two pins to enter EDL on E5788, and when I run a command edl --loader ENPRG9x55.mbn printgpt I get AttributeError: 'NoneType' object has no attribute 'NAND_DEV0_CFG0':

$ ls E5788

I got ENPRG9x55_e5788.mbn.signed from this specific comment https://github.com/bkerler/edl/issues/231#issuecomment-1500187940 and I got ENPRG9x55.mbn and partition.mbn from this other specific comment https://github.com/bkerler/edl/issues/231#issue-1133639214 Trying to use Loaders/qualcomm/model_generic/mdm9x5x/000320e100000000_cc3153a80293939b_fhprg_nand_sim7080.elf or any file in Loaders/qualcomm/patched/mdm9x5x/ as loader would stuck on sahara - Firehose mode detected, uploading.... The same applies to using ENPRG9x55_e5788.mbn.signed and partition.mbn as loaders (I don't know what is the partition.mbn file for, it does not look like a loader).

Now my E5788 would not even boot at all after trying this, it would always go back to EDL mode. Maybe the loader bricked the device?

There's the streaming protocol, but there is also the normal Firehose protocol too. I presume that this is NAND and Secure Boot is not enabled?

[Z9044234820]

There is NAND on the E5788, the log in this issue says "MT29F4G08ABBEA" which is NAND (https://smh-tech.com/micron-mt29f4g08abbea/). The device is unfused according to https://github.com/bkerler/edl/issues/231#issuecomment-1076759449 which I assume means secure boot is not enabled.
