[ZTE Axon 10 Pro Questions & Answers] GrayFox1950:
Hey guys, first of all: BIG THANKS to all of you (especially UD).

Really appreciate all your hard work.

Unfortunately im stuck in EDL-mode after i installed LineageOS and i dont find a way to get out of it.

My model is A2020U:

What did i do:

Full Backup with EDL-Tool (old version! There are some more options available in the new version.. )

unlocked bootloader with fastboot

installed TWRP + Magisk

installed LineageOS (lineage-16.0-20200512-UNOFFICIAL-pine.zip) & reboot phone --> after reboot the phone does not boot OS and im stuck in EDL-mode. No chance to get into recovery or fastboot

Now i cant find a way to unbrick my phone.. I have tried to restore my Backup, but it does not work. i guess i should have used the newest version of the EDL-Tool to backup all my files.. :(

I also tried to flash GEN_NA_P855A03V1.0.0B11_DL with Miflash --> not working because of :

I also tried to flash it with newest EDL-Tool --> Error:

ERROR: C:\EDL_TOOL\flash\full\userdata.img - SPARSE image!!!
ERROR: C:\EDL_TOOL\flash\full\vendor.img - SPARSE image!!!
ERROR: C:\EDL_TOOL\flash\full\system.img - SPARSE image!!!
ERROR: C:\EDL_TOOL\flash\full\system_other. img - SPARSE image!!!

Tried on different clients and USB ports.

You guys have any tips for me? May i try to flash a A2020G EDL (eg. A2020G_PRO_V1.6_FULL_EDL.zip) ? Im not really sure about that, because of G/U model difference.

I am really ready to donate some bucks to someone for any useful tips.. Of course i will also provide any more status updates to this case in the future.

EDIT #1

I used the old version of EDL-Tool to restore my backup-files. Successfully flashed, but my phone is still booting into EDL mode only.

EDIT #2

I tried to move my backup-files into the Flash/Full folder. After starting the flash in EDL-Tool this error occurs:

ERROR: C:\EDL_TOOL\flash\full\rawprogram0.xml - not found !!!
ERROR: C:\EDL_TOOL\flash\full\rawprogram1.xml - not found !!!

I wonder if I can copy these files from GEN_NA_P855A03V1.0.0B11_DL and paste them into my backup?
