So i am having problems retrieving my whatsapp backup chat which is very important to me. Been messing with it for a week now....endless trys with chatgpt. Even tried rooting my phone, reinstalling to get the chat through a local backup. But when i download whatsapp. It keeps trying to want to get the Google drive backup. And gives the message *sorry could not retrieve your chat* of 3.3 GB data.i even got into python, and got the Google drive whatsapp local. appearently Chatgpt says i need android lower version of 13/14 and download an older whatsapp to be able to get it to work. But i have a s21+ with android 15. Which if i download older versions i get either a problem with date or that i am being forced to update.eventually chatgpt advises me to download a pc version of android to get it with older version. But it consumed so much time from me, i didnt bother the last one yet. Because i have to dive onto it and not knowing it works. 

Also decrypting on pc is not realy an option, because i just want the backup to work on whatsapp on phone. Chatgpt says worst case scenario i need to read decrypt the backup, and read it with whatsaapp reader. But i cant get the commands to decrypt either on python/cmd. Also i am an IT guy myself
myself but this is realy unfamilliar for me and a tough one.. 

Help please someone any ideas? Is it bothersome / worth it to get an older phone with older android, and can u even install older whatsapp apk on it and retrieve the whatsapp backup? Since chatgpt claimed i could do it on my s21 with the nice tricks to get older xx.xx versions of whatsapp. But st the end of the road i did everyrhing it told me. Eventually telling me that its near impossible with my android version / phone because the whatsapp is at 14.x... the chats are very important for to get back the chat
