Error with permisions

[Lord VaeL]

I have a Xiaomi 4c and TWRP without rooting. The 4c ​​only has internal memory. The twrp when it opens always asks me to put the memory as read only and I think the last time I opened it was applied. The problem is that now It dont load the twrp and several applications can not save files in memory (I get error that does not have permission) it does not let me install the TWRP again, also using adb (error that I do not have permission). Trying to install it otherwise gives error. I tried to change write permissions but either I do not do it right or I continue without permission. Also it do not let me do hard reset or install another recovery. suggestions?
