[Android General] Juglar:
Hi, Renate, I've seen your great knowledge about this and browsed your admirable Temblast site.

I am trying to make a full backup through EDL of all the partitions in my boot-looped ZTE Nubia Redmagic 7 Pro (after mistakenly trying to downgrade it to a different country stock rom from the Android 13 config), except for the userdata partition, which I already had backed up with QFIL (and programmer prog_firehose_ddr.elf) .

My aim is to recover the phone, but, much more important, its user content, which I ABSOLUTELY don't want to be wiped (nor re-encrypted, of course). My intention is, after backing up, to copy all the _a partitions in slot a (from the Android 13 previously working there) to the current _b, which doesn't boot, hoping it reverts it to the previous working version. (I've tried setting active slot to a by fastboot, but it rejects for locked bootloader, which I dont' want to try to unlock, not to risk wiping userdata).

I'm trying to use your EDL.EXE client, as I believe you about its better reliability than QFIL and because I appreciate its not having to calculate sec nums and its space and time saving /t option.

On Windows 11.

I've replaced my previous drivers by Zadig's WinUsb.

Though my prog_firehose_ddr.elf (plus 2 XML's) seems to work well with Qfil (phone has UFS mem), I was ready to look for the appropriate one in bkerler, but I am having some errors. I log here my serveral trials. Somewhere in the middle, I tried resetting the phone to EDL (I believe before getting the "Bad XML" error)

1 Please, would you be so kind as to explain what may be failing and possible solutions?

Appart, about my general aim, several questions, if you please:

2 Would any of your EDL.EXE options wipe userdata (or change its encryption) ?

3 Do you know if the EDL mode (with any other clients) would "per-se" wipe userdata when dealing with partitions other than "userdata"?

4 Is there any other way of finding out my phone's HWID? Is HWID, as Im beginning to understand, something which uniquely identifies the phone model?

5 If I try to download a full stock rom with QFIL (as it offers), would it wipe my user data?

6 Does your EDL.EXE have a command to do a full stock rom update?

7 Do you think that doing that copy of previously working slot a partitions to their corresponding b could have the possibility of recovering my data?

Sorry for the many questions, but I think they should be short to reply and it would help me a lot ! Don't have any problem in replying that you don't know to any of them.

Thanks in advance !
