[Sony Xperia XZ1 Compact Questions & Answers] seven hole:
EDIT : Downgrade succesful with other firmware (47.1.A.8.49_CE1 ) proposed by [MENTION=4418980]j4nn[/MENTION]

Continuing the process.

Hello all :8) I'm still trying to save Drm keys of the XZ1c .. i got a windows 7 working, all drivers and flashing drivers installed... Adb commands responding . I try to downgrade to get the renotools working and save the DRM keys

- Debug mode and OEM unlock allowed on the phone with the ultimate .228 firmware.

But Newsflasher 20 stop installing the 47.1.A.2324_CE1 firmware (from the link in the @j4nn 's detailed instructions in the thread

https://xdaforums.com/xperia-xz1-compact/development/devonly-exploits-temp-root-to-backup-t3795510 )

- I've put the newsflasher app and tools in the root dir of the Firmware as said in the newsflasher instructions.

- I've unzipped the" partition.zip" , getting a "partition" folder in the same dir

Then start newsflasher (after installing Gordon Gate flashing drivers) with phone on "flash" mode (green light after volume down button + usb cable plug

Skipping all optional options as i read in the "newsflasher thread". i copy the log down there/

Ii can' succeed to flash the firmware ... With luck, the phone continue booting on .228 firmware after this...

-OTHER ASPECT then the @j4nn thread says i should remove the "persist" files from folder to keep attestation keys

But i don't have exactly that file in the firmware folder, but a persist X-FLASH-ALL-C93B.sin file . does it mean i should let it in the folder, or is this an equivalent ?

Thanks for your help and sorry for being such a noob at every step

I put the newsflasher log down here
