Hello Everyone, This is regarding recent upgrade issue on my iPhone. I am still struggling to get access to my iCloud storage data for iMessages, Notes with password, Health related stats, etc. I would like to explain chronology of the entire event. There was a recent IOS 17.4.1 update came on April 07th, 2024. I clicked on the update but nothing happened then suddenly my phone passcode wasn’t working. I restarted my phone then the phone was not even accepting my face id. I went to the Apple store. Apple support team have requested me to reset (erase entire data) iPhone which I had already done on next day. I had no others options actually. My phone passcode was not working in reality due to iso update because I haven’t changed my passcode since more than a year. It is also not due to iPhone screen issue which apple team was saying to me initially. Unfortunately, my Apple ID credentials wasn’t working after phone reset so I had to put my Apple ID on recovery mode which took almost 15days to recover even though process is automated as per apple support team which they can’t reduce it. I understand that they are doing for privacy reason but who wants such privacy when even owner can’t access his own account for 15days. I offered them to verify my personal details such as email ID, phone number, passport number and any other details which they can use to expedite the process but they didn’t help on this. At end of the recovery (after 15days), they used same details i.e. my email ID and SMS on my registered number to verify. I don’t understand their logic but if they can take 2-3 business working days for same process then it makes sense to wait rather than 15days. After I regained access to my apple id, I have restored everything using my iCloud storage. I observed that few applications such as contacts, WhatsApp, etc. are restored properly but some of the applications such as iMessage, Notes (specifically locked notes), health data were not restored. iMessage are not synchronizing with iCloud storage when I tried to do it manually too in setting >> apple id>> iCloud >> show all >> messages in iCloud >> sync now. Nothing happens after clicking on it. Locked notes are still showing an error message “Can’t view Note. ‘This note can’t be viewed because encryption key wasn’t found in iCloud keychain. Resetting your end-to-end encrypted data can cause this’”. I have never used custom password to lock note instead I was using Face ID earlier to lock or unlock some of notes. All these things are happening because it is asking for old iPhone passcode to connect with iCloud storage while resetting my iPhone. I am trying to enter all the previous passcodes. a. When I entered correct passcode, then there is no error but still applications are not synchronizing with iCloud storage. b. When I enter incorrect passcodes (multiple passcodes but one at a time) then it gives an error “Verification failed”. It means it is detecting correct passcode as per above point. There is some issue with passcode synchronization with iCloud storage. I have opened a case with apple support team but meanwhile If any one of you had faced similar problem, then kindly suggest ways to me so I will regain access to some important personal information which are present in my iCloud storage. I would like to inform everyone that don’t rely completely on single brand or product. Take multiple backups may be on personal laptops, SSDs, etc. I learnt a lesson that even apple products, software & services are not reliable so think before buying costly products just for sake of brand name.
