You just have to flash the unofficial twrp to your boot partition then once in TWRP, flash your stock boot image to your boot partition once more and without rebooting, go to the advanced menu in TWRP and choose flash current TWRP
So double flash either or as long as you make it the boot.img? Dammmmmm, now I'm interested in ****in around with the other. a/b sucked when they first started dual, but now I love it. Trying to pull the radio for someone ATM but it keeps getting fragmented. I've even done full dumps. TG4 payload dumper.

You initially flash TWRP to your boot partition while in fastboot since the recovery is now located in the boot partition.. then once booted straight into TWRP, you wanna flash your bone stock boot image back into your boot partition, almost as if you were be resetting it so to speak.. then under the advanced tab in TWRP, choose flash current TWRP to splice the custom recovery back into your boot partition because uf you didn't do this then it'd really start causing problems if you decide to obtain root by way of flashing magisk..

It's a bit convoluted but it's the state of chaos we currently find ourselves with this device

Hey All,

I managed to install TWRP to boot_a partition, boot TWRP, extract my firmware off the phone as a backup called boot_b.img (b is my active slot) and patch boot_b.img with Magisk. I am too scared to flash the patched boot_b.img over boot_b partition so I am trying to flash the patched boot_b.img over the boot_a partition which currently has TWRP. However, when I try to boot boot_a partition where TWRP was, I get a boot loop. A couple questions:
  1. What am I doing wrong?
  2. Why do we have to flash both boot_a and boot_b at the same time?
  3. Should I be flashing vbmeta_a also? I am using the attached vbmeta.img and flashing with “fastboot flash --disable-verity --disable-verification vbmeta_a vbmeta.img”
  4. When I try to flash vbmeta_a, fastboot flash says it uploaded 0KB. Any idea why? DDing to it from TWRP and then rereading the device I just DDed to, shows that DD didn't write anything.

Version Info:
android 12
Build: GN2200_11_C.11 Kernel:5.4.147-qgki-ga9e7460afd8c

Thanks in Advance!
You should also try:

fastboot flash --disable-verity --disable-verification vbmeta_system_a vbmeta_system.img

fastboot flash --disable-verity --disable-verification vbmeta_vendor_a vbmeta_vendor.img

fastboot flash --disable-verity --disable-verification vendor_boot_a vendor_boot.img

If that still doesn't work then try switching slots after flashing and worst case scenario just format your data partition and try again

Aight cool. Yeah I just wanted to make sure it wasn't like the 7 & 8 where you had to boot straight into recovery from Fastboot then flash from recovery..... Has anyone tried fukin around with some of the more flexible recoveries like 🍊🦊 or Pitch Black? SkyHawk is always a thought too. 🧐 Damn, now I'm gonna be runnin it in my head all day, till I'm done making the donuts.

A couple questions:
  1. What images am I supposed to use for vbmeta_system.img, vbmeta_vendor.img, vendor_boot.img? You didn't say to flash boot_a also, but I flashed boot_a with the image that was patched with Magisk.
  2. Is there any connection between vendor_boot_a and boot_a?
  3. Am I required to disable verity and verification in order to root the phone?

Probably there's a connection between the two. all the images work hand and hand . You only need to patch the boot.img , and flash it to obtain root. You can patch either boot_a or boot_b I would not patch both of them Incase you brick your phone so you have either or to fall back on. If you booting on b patch and flash b , and vice versa.

I'm back on this thread. I currently have a Nord n300 , and a revvl 6 pro. I want to figure all this out, so We all can work on the future of modifying technology. I want the n30 wanna do all this on that it just dropped a week or so ago. Then the n40 fast-forward 2024 ⏩. If they allow it it should be able to be done . This thread is about the Nord n20 gn200 or any *model of Nord n20 *if you can make use of the information.

Since I'm currently booting off boot_b, I patched boot_a and switched the boot partition to boot_a, cuz I could switch it back to boot_b if the boot failed. I'm glad I touched only boot_a because I got stuck in a boot loop and was able to set my boot partition back to boot_b and have an operational phone again.

Hi I'm new and green as hell but would like to learn all I can and right now I'm sitting here just deciding whether I want to get an N20 or N30 and I'm leaning more towards N20 if I can debloat it because I'm not looking to flash custom roms or anything like that I just want to develop my phone so that it runs smooth without lag and all the other bloat induced problems. Ideally I would like to modify the ROM but I would settle for debloating it however if I can add a few of my favorite apps in place of the stuff I removed that would be perfect.
I hate having system apps I'll never use and there are some that I would just like to behave so if I can get rid of a system app and reinstall the same app from the play store or something like that as a user app that I have a little more control over this too would be good. I think I would like the AMOLED display and I think I can make 6 gigs of RAM work just fine if I can make my phone run a little leaner but I noticed someone mentioned N40 which sounds likely and if that is the case I can definitely skip the N30 and wait to see what the future holds in store for the Nord series.
Would anyone recommend one over the other considering what I would like to do with them because I'm not really keen on the newest version of Android and I think support for older version would be a little more inclusive and if I get the N20 can you fine folks here help me accomplish my objectives?

Hey man I have the N20 and am willing to work together to help get a successful root on it, because I haven't been able to root it so far. I also heard that newer phones take longer to root because nobody knows the software very well yet. Therefore I would recommend the N20.

Thanks for responding so I am assuming you must like yours after rooting it, that's a good start. I usually rank RAM as possibly the single most important specification for consideration but with the exception of two phones I had way back when one click rooting allowed me to debloat my phone and install xposed I've been stuck with carrier budget phones that don't allow me to do anything beyond paying my bill. So did you de-bloat yours and if so how much of a difference did that make in performance? I asked a lot of my phone and unfairly treated as if it were much more expensive phone but this is likely all I will be doing at least for the time being until I'm a little more comfortable with my abilities because I definitely can't afford to replace a phone stuck in door stop / paperweight mode. I thought for sure I knew what I wanted (N30) until it became available and now a bunch of uncertainty is creeping back in. I had pixel 6A and Galaxy a54 in the running also but immediately ruled them both out because it's Google and Samsung whose overreaching and anti-competitive business practices I despise so please allow me a couple more days to make a decision if you don't mind and thanks again for responding so quickly

Hey guys! I'm relatively new here; been lurking forever but never actually following through with anything. Anyway,

I have a Oneplus N20 5G with Android 12, June 5th security update. It's running GN2200_11_C.14 and I'm also going for root. My bootloader is still locked and everything, as a matter of fact it's still FRP locked.

Not sure if I can be of any help at all, but this is to be my practice phone as I am very new to all of this. I've rooted a few Moto Stylus and an HTC but I am overall a complete greenhorn. I was hoping to really cut my teeth on this one+!!!
