So basically you connect your phone to the computer. Make sure you have automatic updates shutoff. Start downloading the update, but don't download it all the way . Pause it after 15 seconds. Type " adb logcat > ota.txt " without quotation . In you platform tools folder there should be a file called it's.txt open it . In the search type " googleapis " and you will find a httpslink.zip copy it and paste it in your browser it should start downloading. Extract the downloaded file. The payload will be in the extracted folder.
Ota.txt** not it's.txt
I have steps for you on how to extract the payload.bin file with payload_dumper-master... Once you got a capture of your ota
Also I have telegram, but I need to download it.
I sent message on telegram
Platform-tools directory in terminal type that command*
Also I had android 11 at first . I did end up bricking my phone trying to install a unofficial TWRP. I thought I was never get my phone back working then I tried to flash different boot.img . I flashed it with different ppls images. Still nothing. Kept doing research. Flashed it more had a phone that finally turned on , but no wifi .... I flashed the October patch android 11 flashed vbmeta , boot image , system.image system_etc.img . I finally was able to turn on my phone have wifi. I noticed there was a new update . I was just gonna download the update to fully get my phone back to normal, but this was my chance to root it cause all the software lined up . I figured out how to capture ota . I capture the ota to my version of the new update. I downloaded my update for Android 12. I patched the boot.img . BOOM
flashed it phone successfully rooted . New update to Android 12 and root.
So my phone is currently rooted on the android 12 , but there is a new update . What I'm trying to figure out is how to update it. It seems you can only get the boot.img with full ota . With be android 11 at first . Android 12 was a full ota. Since I'm on android 12 there is a new update, but it's not a full ota . It's a incremental meaning not all the software is getting modified. I did manage to capture my incremental update , and you'll know it's not a full ota if it's only like 100mb. full ota are like 4gb . So I have the payloads for both updates. I'm trying to combine/extract both payload.bins boot.img combine them together to have a new updated root . My phone is still rooted properly . I would just like to stay up to date.
