According to tipster Ice Universe, Samsung has disabled Odin, a proprietary firmware flashing tool typically used to install stock firmware, install custom ROMs, and restore devices. It also appears that Samsung has removed “Download Mode,” which acts as a gateway for Odin. This change appears to have been made in the latest One UI 8.5 firmware and currently affects the Galaxy Z Fold 7 and recently launched Galaxy S26 series.
The only answer is regulation. We need laws that say, if you own a device, you can do anything you want to it, including wipe it, hack it, resell it, etc.
If they want to control your device, or lease it to you provided you pay a monthly fee, etc, they need to say “Lease”, “Rent” or similar, not buy.
And they shouldn’t be able to void your warranty for it - voids should be limited to the parts of the device you mess with. Like, if you flash your phone, they should be able to say, we can’t give you support, including how to re-install the original OS…but if your battery fails and it shocks you, they should have to replace the battery under a warranty.
We also need laws that say, if you pay for a device, that device itself, can’t have ads. So like, when talking about Android TV boxes, they can put recommendations on the homepage, but not ads, and those recommendations can’t be paid. Now, if you open youtube, they can make you watch ads.
