PS4 11.02 downgrade with status "Overwritten CoreOs slot"

[joaonn13]

Hello everybody,

After the necessary material arrived to start my adventure in version 11.02 regression, I came across the following message "Overwritten CoreOs slot". As there is not much information or tutorials on the topic, I would like to ask the following questions: If the information shows 11.00 to 11.50, it seems to me that at some point, the console downloaded 11.52, despite the NOR being on 11.02. Is there any solution for this?

Thanks
João

Boas Joao , isso significa que sobrescreveste o firmware 11.02 no slot coreos , esse slot apenas deveria ser para leitura onde está a info do firmware anterior a 11.02 mas como sobrescreveste ficheiros do 11.02 encima desse slot . nao vai ser possivel reverter ..

Hello Joao, this means that you overwrote the 11.02 firmware in the coreos slot, this slot should only be for reading where the information from the firmware prior to 11.02 is but as you overwrote 11.02 files on top of that slot. It will not be possible to reverse it..

Mod Edit: Please provide an English translation with your post.

Obrigado, João.
Segui o vídeo do Modded Warfare"Reverting a PS4 from 10.01 to a Jailbreakable Firmware (Full Guide)" e o que li hoje, as consolas podem não ter feito o upgrade para a versão, mas ela descarrega, escreve e esmaga a versão que lá estava que devia ser a 11.00. Existe um vídeo, onde mostra como é possível verificar a versão que está a consola e nas notificações é possível ver se ela descarregou a versão a cima, apesar de estar na 11.02. Neste momento não existe forma para dar a volta (penso que não), porque gravei a sflash01_slot_switch_3.bin e sflash01_slot_switch_4.bin e na 3 dá a mensagem de arranque de 11.52 , e gravando a 4 arranca normalmente o sistema na 11.02

Thank you, John.
I followed the Modded Warfare video"Reverting a PS4 from 10.01 to a Jailbreakable Firmware (Full Guide)" and what I read today, the consoles may not have upgraded to the version, but it downloads, writes and smashes the version that there It was supposed to be 11.00. There is a video, which shows how it is possible to check the version the console is on and in the notifications it is possible to see if it has downloaded the above version, despite being on 11.02.
At this moment there is no way to get around it (I don't think so), because I saved sflash01_slot_switch_3.bin and sflash01_slot_switch_4.bin and 3 gives the 11.52 boot message, and saving 4 normally starts the system in 11.02

Also, afaik, the downgrading method only works on a few chipsets. I'm not an expert on it though, but I seem to remember a diagram from @BwE . I think he was on this site at some point. Could be wrong though.

Obrigado, pela referencia.
Eu ainda estou a tentar perceber como funciona o processo de regressão, mas o que não sabia era, se a consola fizer o download a versão acima ela vai escrever por cima da versão antiga que estava guardada. Existem 2 repositórios, um onde guarda a versão antiga e outro onde arranca a versão recente. Dando o exemplo, eu devia ter num dos repositórios, a versão 11.00 e depois actualizei para a 11.02. No entanto, sem me aperceber a consola descarregou a versão 11.50. O que li é que foi escrever no repositório onde estava guardada a versão 11.00. Infelizmente, não encontro muita informação sobre este processo, ou então sou eu que não estou a saber procurar

Thank you for the reference.
I'm still trying to understand how the regression process works, but what I didn't know was, if the console downloads the above version it will write over the old version that was saved. There are 2 repositories, one where the old version is stored and the other where the recent version is loaded. Giving an example, I should have version 11.00 in one of the repositories and then I updated it to 11.02. However, without me realizing it, the console downloaded version 11.50. What I read is that it was written to the repository where version 11.00 was stored. Unfortunately, I can't find much information about this process, or maybe I just don't know how to look
