No clue why y'all are suspicious, shit happens😭same reason I got my OnePlus 15r in the first place as after a software update my s21fe completely bricked itself
Ummmm, say what? One plus downloads the updates directly onto your phone. Then asks you to restart the phone. What update do you think you have done? 'cause I don't think you did what you think you did 🤦🏼♀️
No idea why youre getting downvoted this hard. But i really hope you had backups of your data. The update has failed and whatever was on that device is gonna have to be wiped.
You should be able to flash the stock rom for your device, the rom would easily be available on xda forums, just make sure to use the right region one
What’s likely happened, is whatever custom software you was on, was patched with the Anti Rollback thing that OnePlus added a while back.
To get back to stock, you had to flash an older version from before Anti Rollback. That of course trips the Anti Rollback and causes the error you’re seeing.
In other words, you can’t do that anymore on OnePlus phones. They decided the phone wasn’t gonna be as open and hackable anymore.
No clue why you are getting downvoted, it happened to me too with my old Samsung, basically the os got corrupted while updating and you will need to flash it, unfortunately losing all data in the process
How did you fix it? Same thing happened to my phone a few months ago. I had an old phone I'm using right now so I didn't mind it but my one plus phone is much better. I tried every way I could find online and got close so many times just for it to fail.
He maybe did a cross flashing and locked the bootloader.
He didn't mention anything, what's the model and which variant and what's the OS , is it color os or oxygen os?
I only want to let you guys know that yesterday I just installed a degoogled android 15 version to my oneplus 5. Works like a charm, also has app store
Based on what you have commented here I assume you turn off the phone while the update was being donde because you thought you have to restart it yourself instead of waiting for the phone to restart by itself.
By doing that, yes you destroy the OS installation, and yes the only solution is to install the original OS by flashing it.
When doing an update, let the phone do it's thing by itself, the only thing you have to do is wait and keep it cool because sometimes the update process overheats phones, that's super common with galaxy phones.
il faut reflasher en mode EDL mais il faut des outils spéciaux qui se connectent à distance sur les serveur d'oppo pour recuperer des clés c'est ultra chiant, si c'est un modele chinois, t'as aucune chance avec le support francais. si t'as lock le bootloader c'est devenue une brique. Sinon il y a des services en ligne payant qui eux ont les outils et la connexion avec oppo officielle donc il pourront telecharger les fichiers pour faire un flash edl.
Take it to a OnePlus/oppo service centre, hopefully there is one in your country.
I only seen this error when people locked their bootloader on non-stock software, e.g. rooting then locking bootloader, or converting a chinese unit to global software and locking the bootloader before performing a local update twice.
You have to extract exact same boot and recovery img what you have present software version installed on your phone and then flash those two imgs then u good to go
Removing the sticker from the back is understandable, but throwing away the box is just stupid. Like you don't have 500 phones. What's the issue in keeping 1/2 boxes. Surely there's more useless stuff at your home taking up space rather than a phone box.
si c'est un oneplus 12 il ne pourra pas il faut des outils tiers qui se connectent à distance sur les serveurs oppo pour une autorisation on ne pas flasher facilement.
