Just only FASTBOOT works

Sep 21, 2014
After installing with success this ROM : "xiaomi.eu_multi_aqua_V7.3.1.0.LAJCNDD_v7-5.1.zip" on my XIAOMI MI 4s, I've tryed to install Android 7 with : "xiaomi.eu_multi_MI4s_V8.5.2.0.NAJCNED_v8-7.0.zip" via TWRP 3.0.3 but the installaton was suddenly interrupted and now just only FASTBOOT is working (no recovery, nothing else). I have also tryed to restart from factory chines image ROM;"aqua_images_V8.5.2.0.NAJCNED_20170727.0000.00_7.0_cn_b8a4113bca.tgz" but I got the following message :


What can I do now to see mi MI 4s alive again?
Thank you.
