I just realized, if i only have stable internet on my side, my problem must be already resolved in one day, seeing everything works with minimal internet. Im typing this now in a text-only search engine called free basics, and limits me to open websites in text mode only and cant upload files, even kilobyte sized ones. I only rely to my parents' data subscription (since im only 18) so im just waiting my chance when i am able to use it.
For the meantime, this delay may be longer, and im just letting you know about my situation. Sorry for the great delay.
Wait... Can i just copy-paste the logfiles instead rather than attaching? I can make a way for it to send the text from my computer to my phone. For the CBS log i can just do a sfc scan, remember when i start the scan, and copy the text from that time (or 1 minute less to be sure) to the latest to reduce text flood here. What do you think?
