I was on B511, however I used a TWRP backup to restore into B513, and then rooted the phone to correct the vendor and country info. Now I am on B513, rooted with TWRP recovery. I suppose what I need to do is
1. Flash stock recovery
2. Put the downgrade pack in Dload folder in my SD card.
3. Go to project menu and do a software upgrade.

Is there anything that I have missed? Do I need to unroot? I see you have not mentioned the vendor and country info anywhere in your post. Is that not necessary?

Now you have b500. Install twrp and flash backup b513 and do it wipe. When you do it you lost your hw eu but you can restore manual using fx Explorer when you do it uproot and install stock recovery then flash rollback b300 or b500 what you want

ro.product.model=JAZZ
to
ro.build.flavor=MT7-TL10-user
ro.product.model=HUAWEI MT7-TL10

Hello, guys, I had the same problem (boot loop) on MT7-L09 and my bootloader was locked. I put B500 in dload, flashed with +/-/Power and it reached 100%. However, the phone does not boot, it's still in the boot loop. Should I flash B331 if I can't boot into B500?
