Question about flashing / fastboot

[Guest RedSlug]

I know you can flash the baseband, and you can flash the DSP, and obviously you can flash the OS (Framework??)

Is there anything else you can flash?

you missed recovery

DT doesn't work and is a bad idea to try B)

not tested the others..

[Guest RedSlug]

Yes, but what is DT, and what are the others. B) Where can I find out?

[Guest BigBlue007]

Well, these are the files that I can see in a decrypted .pkg:

amss.mbn (baseband?)

appsboot.mbn (?)

boot.img (self-explaining)

dbl.mbn (?)

dsp1.mbn (self-explaining)

dt.img (?)

fsbl.mbn (?)

osbl.mbn (?)

The main system doesn't seem to be an .mbn or .img file in the .pkg packages, instead there's folder "/system" which seem to contain the whole system files directory. Also, there is a folder "/recover" in which there is a recovery image and a script that installs it anytime during the .pkg installation process.

Does that help? B)

By the way, in order to get a .pkg decrypted, you just need to flash it from SD using recovery. After flashing it (or maybe even if the flashing fails with a FOTA error or something), you will find an update.pkg.dec on your SD card, which is a ZIP file that you can open as any other ZIP. I would however not recommend to play with these files, unless you know what you're doing. Which you probably don't (me neither btw). No offense... :)

Well, these are the files that I can see in a decrypted .pkg:

amss.mbn (Cellular Modem Software(aka baseband)

appsboot.mbn (I THINK its first stage recovery)

boot.img (Android Boot Kernel and init ramdisk)

dbl.mbn (?)

dsp1.mbn (Digital Signal Processor(DSP) firmware)

dt.img (Suspected to be Bootloader OR Fastboot related - DONT FLASH THIS MANUALLY!!!)

fsbl.mbn (?)

osbl.mbn (?)

allow me to edit your post and give some info B)

[Guest BigBlue007]

No problem. B)

So when Dell supply an update.pkg file, does it contain all of these images? So a PKG file, will update the entire phone. Where as the (awesome) update.zip files we get from Steve maybe just a few of these?

yes ( you can also flash the update.pkg.dec (which gets dumped on the sdcard by a bad flash) by renaming it to zip from dec, through clockwork but it only flashes the system and amss that way)

you can see what fsbl & osbl contains in a hex editor..

fbsl I think is the fastboot, born out by the first line of clear text in there

fbsl_dload HighSpeedUSBCore

Obsl is the download mode for use with lowlevel flashing tool

OSBL MCP micron 4G/4G

OSBL MCP SAMSUNG

OSBL MCP HYNIX

OSBL MCP UNKNOWN

Press volume-upkey to enter Download mode

contains partition information that is flashed by oem

AMSS APPS APPSBL DT RESERVED SIM_SECURE OSBL DSP1 DSP2

its the sim_secure that contains the sim locking stuff I think

DBL is Dell Boot Loader

DT is Diagnostic Test mode.. if you go into fastboot (camera and power) then instead of selecting fastboot, press the left hand option, it runs some diagnostic tests

Appsboot appears to contain flashing information.. as a userdata partition.
