Hi there, I have a problem. After updating iOS to the 26 Beta, I had to replace the battery because the original one was completely ruined—both the flex cable and the BMS were irreversibly damaged. I installed a new battery, but ever since then, the phone boots up in Recovery Mode. I can only get into DFU mode by attempting a restore via Apple Devices; the restore process stops, the phone gets stuck, and only then can I put it into DFU mode. Now, after about a year, I'm revisiting the issue. I'm trying to install iOS 27. The flash succeeds in 3uTools, but the phone still boots into Recovery Mode. Does anyone have any ideas what this could be? Has anyone else encountered this problem?
