From firmware 0170901 I tried a claud update with CIUPDATE, which has been replied by OK.
After this, a reset happens with a last line telling: jump to user 2. And I lost control about the ESP.

I have performed the CIUPDATE without and with grounded GPIO2, without any difference.
How I may jump out of this trap?
I run a ESP-01.
Many thanks and best regards
Walter

- Thu Dec 11, 2014 5:29 pm #4613 I have restored a ESP-01 that I thought was definitively bricked with ESP8266_flasher_V00180902_03.zip, found at
https://drive.google.com/folderview?id= ... ptbzg#list (link from the Espressif BBS)
GPIO2 to high, GPIO0 to ground, click on the Start button (the only one on the first tab) and pull RESET to ground, it should start flashing AT0.18+v9.0.2, there is progress on the last tab (paste to google translate)
This also worked with the new 9.0.3 f/w

Many thanks for your quick answer. I tried your suggested flasher, it loads and green light appears, but after this, the ESP does not respond.
Fortunately, I always can go back to 0017.

Best regards
Walter
