[@Freefallr60]

I never experienced a video quite like this before. you went slow, without any arrogance, did the painful part of redoing and huge amount of editing, to the point of near perfection. Nice confident chill voice. (as in "this will be fixed"). I just had to tell you of my experience, and offer a couple of bucks. I hope a million give you a buck or so! And here's why. One can only do something so great like this, only if they truly care about their brothers and sisters. This video is deeper than just tossing up a fix-it video. Hats Off! Bravo! Thank you so much! I've been brain dead today, making so many mistakes. I'm a young 61 year old male, and I kept getting stuck while putting in a new SSD. Silly errors, probably from not being attentive. I've done this once before also. Your second fix is what finally ended the humbling journey. I couldn't advance with the "now" properly written software. It kept writing, no software.

[@RajdeepBiswasInd]

Recently after update, I started getting error "connect an usb storage that contains update for re-installation of 11.50 or later". Faced this three times and I decided it's time to youtube. I chose "Rebuild Database" and restarted 4 times and its working as before. Thanks a ton. You have given many options with patience. UPDATE. The fix only lasted few days. But after reinitializing system with downloaded update from PS website via USB, its been a week and the issue didn't reappear.

[@rachaelcatleesi180]

The new update had my system nearly bricked today. I was in tears and had no idea where to start. Thank you for giving me a guideline and many new things to try, and for doing so in an easy to follow, relatable way. In the end, I had to reinstall (luckily most of my game, stats, trophies, etc. had been saved to my profile) but, thanks to this video, I really feel like I learned a lot of new things and am more prepared should this (hopefully not) happen again. Such a pain in the rear to have to download apps and sign in all over again, but worth it! Many, many thanks.

I have the most recent updated reinstallation, it takes and is downloading and when it's done my PS4 turns off then comes back on and it's in safe mode again asking me to reinstall the software again. It keeps looping over and over to safe mode and I just don't know what to do anymore. I feel like I've tried everything.

Since we in Montenegro do not have an authorized service for Montenegro, I turn to you for help. Namely, the problem occurred on the ps4 when the new update 8.00 came out. During the update, it blocked and later there is no chance that he wanted to do the update anymore. I tried deleting the update but still did not want to update. Later I tried via usb in safe mode but also brakes there at 11%. Later I tried to rebuild data but it still doesn't allow anything but update and blocks at 11% of the update. Later I tried initialization, reset to factory settings but even then it didn't want to update. Later I tried to install a new system but blocked 9% of installations and so on countless times. Tried with a new hdd but the same problem.

None of the simple solutions worked so I had to wipe out all my data from the ps4, but I can now use it so no problem. After that I re-install my user along with genshin impact and the youtube app, played GI for a couple of hours with 0 issues, closed the game and turn off the console, the next day the ps4 tells me data is corrupted and I'm back to not being able to start my ps4. By the way options 4 and 5 just flat out refuse to respond. With option 4 the progress bar gets stuck at 99% and then says something is wrong. Option 5 doesn't even respond, after I press X to start the process it lags a few seconds and an error message pops out.
