I hardbricked my N20 by installing CPH2459 files on GN2200. I believe I didn't put dm-verity cmd in my vbmeta flash line on fatsboot.

I want to point out that if you hard brick, EDL has authentication, so there is no way to "fix" the phone and get fastboot back to recovery it all. I have spent 2-3 days on it now. Probably will see if Oneplus can rma/flash it. I have tried Qfil, MSM Download, Rombox (the screenshot on XDA show N20 but the actual application doesn't have it).

If anybody has a solution please let do me know otherwise just letting you know EDL has authentication won't let you flash thru firehose.

message from EDl using Qfil:

INFO: TARGET SAID: 'INFO: VIP is enabled, receiving the signed table of size 8192'
INFO: TARGET SAID: 'ERROR: Verifying signature failed with 3'
INFO: TARGET SAID: 'ERROR: Authentication of signed hash failed 0'
INFO: fh.attrs.MaxPayloadSizeToTargetInBytes = 1048576
NFO: fh.attrs.MaxPayloadSizeToTargetInBytesSupported = 1048576
INFO: Something failed. The target rejected your <configure>. Please inspect log for more information

Unfortunately I have no experience in EDL. I've never had to use it.

My phone is currently a paper weight too. I did the Android 12 update and now my touch screen is not responding I'm on my way to T-Mobile I have insurance.

I bricked my MI A3 a few years back by flashing a ROM to the wrong slot (a/b)... I didn't know any better. I had to take off the glass back and jump it into EDL mode with a staple. It was tricky as you had to tap the jumper pads at the precise moment to actually get it into EDL mode. Someone on here PM'd me and I had to connect remotely with a person in Russia (seemed shady) with an authorized Xiaomi account to flash it back to stock ROM. $28 I think I paid, fortunately the guy was legit.

open telegram and search for XIAOMI REALME Unbrick .... then follow the bot prompts.... they charge but were not allowed to post links to pay services. Not expensive and the responders are legit. expect just above a Jackson ... but not more than Jackson plus Hamilton.... lol

the things it takes to fly under radar.

Nor did I, just sharing my experience on what I had to do to unbrick my Mi A3. I'm in the US, so I had no other option really.

OnePlus will return you to stock remotely if it becomes beyond repair.

Also there are a few adb and fastboot capable apks but I am fairly certain it would violate the forums rules to name them.

I wouldn't know how, I'm just able to follow guides on how to root, flash ROMS etc. I have little understanding about that.

Thanks anyway but but never mind I went to T-Mobile and getting my phone replaced I get to unlock the bootloader all over again hooray
