Flashed Pixel 4a with Pixel 5 image by mistake - Google Pixel 4a Questions & Answers

Hello,
I'm desperate and i hope to find here any kind of help to get my phone works again.
By mistake i flashed my Phone pixel 4a with a pixel 5 image, now my phone pixel 4a is stuck in QDL mode, and not responding to any of recovery/fastboot key combination "power+volume up or down or both".
For the last 2 days i was surfing online, and i found out that, that i need a factory mbn file to flash the phone using QFiL to regain fastboot mode and be able to flash the phone with the right stock image.
Could anyone please help me or guide me, where can i find the pixel 4a mbn file, or maybe build it from google source code, or maybe another solution i don't know about to get my phone working again?!
Any help would be so appreciated.
Thank you

Maybe you can use Android Image Kitchen (https://forum.xda-developers.com/t/...kernel-ramdisk-win-android-linux-mac.2073775/) and find the mdn file in one of the stock Pixel 4a images.

Thank you for your reply.
Just to make sure, it's mbn file what I'm looking for, not mdn.

Anyone could help me please with Android Image Kitchen, I tried it, but I don't know how exactly to get the mbn file, as far as i know, mbn file is some kind of factory image that in hex format file with .mbn extension.
The main cause of this issue, that the bootloader.img which get flashed first, is the one caused the phone to reboot and stuck into QDL mode.

Run the "unpackimg.bat" file on the stock bootloader.img and see if that file is in the extracted files of the bootloader.

That is what i get:
Android Image Kitchen - UnpackImg Script
by osm0sis @ xda-developers
Supplied image: bootloader-sunfish-s5-0.3-7062598.img
Setting up work folders...
Unrecognized format.
Error!

I've used it to unpack a TWRP image, and it extracted all the files of it fine.
I guess google is using some other format for their img.

It is working fine with boot.img, system.img, but not with this one bootloader-sunfish-s5-0.3-7062598.img, and that file when i run imjtool, it extracted the following files:
abl
aop
cmnlib
cmnlib64
devcfg
hyp
keymaster
logfs
qupfw
tz
uefisecapp
xbl
xbl_config
and sure none of them is not mbn file.

How do you know you phone is stuck in this "QDL" mode?
Can you shut off the phone?
And when you press and hold vol-down and power on - what happens?
Also, I found this thread that the last post seems to say that it took 5 full minutes for the phone to be accessible:

The phone does not respond to power+volume key combination, and when i connected to windows machine it shows up in device manager "qualcomm HS-USB 9008" and on Linux when i run lsusb command it shows Qualcomm QDL mode.
I'll go through that post and give it a try.
I really appreciate the help, and thank you so much for your time.

I believe the file is in the super_empty.img ,which can't be extracted or viewed ,check pixal 4a guides I have a post with info and pictures and files of imgs extracted there ,I sent my phone back for rreplacement

I would like to thank everyone who tried to help me here, I really appreciate your time trying to do so.
Please allow me to explain it again, because none of the solutions above can solve my issue:
I flashed my phone pixel 4a with a pixel 5 image by mistake, as you can see in flash-all.sh script, the first step is to flash the bootloader.img file, and then reboot, my phone did that flash for bootloader.img and rebooted to QDL mode, and stuck there, black screen of death, none of the key combinations work, power+volume up or down or both. The only thing that shows my phone is still alive is when i connect it to a Linux machine and run lsusb command it shows this:
Qualcomm, Inc. Gobi Wireless Modem (QDL mode)
and on Windows, the device manager shows:
Qualcomm HS-USB 9008
My phone pixel 4a has no fastboot mode or recovery mode, only QDL mode, and as far as i know from the research i did on the last 3 days, that i need a factory image mbn file for pixel 4a, which i can use it to flash my phone using QFiL(qualcomm flash image loader) and regain fastboot mode, and that mbn file i do not know where can i get it or how to generate it.
Thank you and may God bless you all

If you can get a donor device and place the phone in download mode you should be able to extract and pull the data and files to fix the phone , all it takes is the mdm file which just creates the partitions ,and the qpst program from qualcomm

I am unsure first time I've used the program but there is a one called emmc software download that seems useful , also the files need are in super_empty.img , if you can find a way to extract it ,it will have the files needed to fix it , I already got my replacement device so I can not test anything only try to obtain files ,super_empty.img is the partition layout to restore the system and include the radio firmware to give you service

GUIDE: eRecovery / HiSuite failing to restore - RESCUE on PIE: L29 L09 432 -- v190

WARNING
By doing this you may lose your data, this is intended for when you have nowhere else to turn to.
Back Story
Hi All,
Like a massive child I stupidly jumped on the Pie bandwagon away from a very well maintained Honor 10 ROM which ran beautifully on my P20 Pro..
After restoring EMUI, the PIE update quickly made itself visible, so i took a deep breath and committed.
After the installation, I tried to install a bunch of ROM's, I messed up a bit.
Anyway, what I found was, I was unable to recovery from eRecovery OR HiSuite, so I then found myself on the wobbly road that is restoring each parition via the bootloader using fastboot, tried to install just the recovery_ramdisk, didn't work, tried to install, kernel / cust / system / recovery_ramdisk..... STILL Didn't work.
So i downloaded another firmware, this time the exact version i was using albeit for the L-09 and not the L-29, I needed to extract the update part of the zip then read it using a tool called firmware extractor.
Ton of files in there, the files i just mentioned which are all .img files and some others.
In the end i needed several to get a perfect restore which has worked every single time without fail.
As it was a massive ballache and a learning curve for me as I'd never done it before, so I thought i'd share my experience and the files required on Mega so there aren't any ads blocking your way Yaay, also what to do and where to obtain the firmwares from my experiences.
Hope it helps someone avoid the pain I had to go through when downloading firmwares for 5 hours at a time, wasn't fun.
Good luck, any questions let me know. :good:
START HERE
*NOTE: You can do this from scratch by downloading the firmware for your device, i required 9.0.0.190 for the L29 - c432.
The best place I found was this site https://support.halabtech.com/index.php?a=downloads&b=file&c=download&id=105974
They require an account to be made but besides that they were faster and had more choice.
Once you have the firmware you'll need the Extractor, then you'll need to move several of the files into the ADB folder for flashing, see below...
Anyway, moving on........
FILES
At the foot of this guide is a link, inside it is everything you should require in order to complete this guide
ADB - Move this folder to the root of C, it should be like this C:\ADB (reason for this is it's much easier to navigate to, most people will already have this)
IMG Files for 9.0.0.190 - All of the file names you see below are img files which we'll be using to un-brick / recover / restore your device to a functional state.
Move all of them after downloading to the ADB folder in C:\ADB
CACHE.img
CUST.img
ERECOVERY_RAMDI.img
KERNEL.img
RECOVERY_RAMDIS.img
USERDATA.img
VENDOR.img
SYSTEM.img
EMUI Extractor - Not a part of this guide but you will need it should you need to download your own firmware and obtain the above files.
Pre-requisites
- A device on a maximum firmware of 9.0.0.190 (If you are on a higher firmware, then use the link above to obtain it)
- A device variant of either L-09 or L-29 (others may work but i have not tested)
- A device variant of c432 (the 782 may work but i have not tested)
- Access to the bootloader (white screen with vol down and power whilst connected to a laptop)
- Drivers so that fastboot / adb commands can be sent to your device (I won't show how to do this, it's pretty standard stuff)
- I have an unlocked bootloader myself and OEM unlocking is on (REQUIRED)
- A Windows based PC /Laptop and a functional USB-C cable. (I'm sure you can
GUIDE
On your computer / laptop
STEP 1 Download all the files from the mega link provided.
STEP 2 Copy the ADB Folder to the root of C: so it looks like this
C:\ADB
STEP 3 Open the folder called "IMG Files for 9.0.0.190" Copy the .IMG files to the ADB folder so they are loose.
STEP 4 Press Start / Windows key and type in cmd then press enter, a black window will appear
STEP 5 In the black window type the following:
cd c:\adb then press Enter
STEP 6 Connect your phone to your laptop using the USB-C cable and allow it to be seen by windows
On your Phone
STEP 7 Press and hold the power button and volume down, don't let go, your screen will go blank, once it turns back on, release the power key but continue holding vol down, a white screen should appear, you can now release the power volume key, you are now in fastboot mode and can input commands.
On your computer / laptop
Step 8 Click the CMD window and type in the following commands, you will have to wait for them to go all the way through, some take longer ie: System.img
*NOTE: For speed you can use the tab key to pre fill certain words or files, so if you've typed in "Fastboot flash cust "
You could then press the tab key and scroll through the files in the folder.
eg: if you were to press enter with this command listed fastboot flash cust c after pressing tab it would say fastboot flash cust CUST.img
PRESS ENTER AFTER EACH COMMAND, MAKE SURE EACH ONE COMPLETES.
fastboot flash cust CUST.img
fastboot flash cache CACHE.img
fastboot flash recovery_ramdisk RECOVERY_RAMDIS.img
fastboot flash userdata USERDATA.img
fastboot flash kernel KERNEL.img
fastboot flash vendor VENDOR.img
fastboot flash system SYSTEM.img
STEP 9 Once they've all been flashed, in CMD simply type the below command and allow the device to boot up, you can disconnect now.
fastboot reboot
If all has worked and it should have, then you will have a stock ROM of PIE on 9.0.0.190
You can then root and use your device as you see fit.
Here is the link to the said files (WHICH WILL NOT BE TAKEN DOWN )
NOTE: they actually now have, sorry

As I said in the guide you need OEM to be unlocked. I have no idea how you can unlock it without accessing the system. I think one version of pie locked it down but then the next one unlocked it.
Did you turn off OEM unlocking yourself?
What version are you on?
Maybe a paid service can help mate. Not sure.

OEM unlocking needs to be off mate, 108 shouldn't matter but i believe that it's the version that has the OEM greyed out.
There is a way around it but i'm not sure.

Certainly not with this method as you don't meet the pre-requisites.
That being said I suppose some kind of low level flash tool may work, like i said before a paid for service maybe?
Lets find out everything there is to know.
So your bootloader is unlocked.
Have do you have TWRP installed?
Did any of the images i've listed actually flash successfully?
Have you tried to use eRecovery? or Hi Suite (neither of these worked for me hence this guide)
Beyond that i suppose the only way would be a paid service but their pre-requisites may be the same as mine. In that case I would say you're out of luck, afaik this guide is essentially the lowest you can go. I don't believe anything will work without OEM unlocking turned on.
How do you get onto the firmware you're currently on ? 108 and what state is the phone in right now?
What works? Whats accessible?
@dladz thanks for the guide. You got me out of a jam already and this useful information to restore to stock.

Used your guide @dladz, everything flashed perfectly but on the fastboot reboot command, the PC made a noise to say the USB had disconnected as expected.
All I've got is a black screen and red flashing LED.

Weird. Not sure pal. This is what I did when I was stuck. Did you read everything and follow to the letter? A higher or same firmware?
On fastboot reboot the pc saying it's disconnected is correct. Should have come on.
Does anything ever come on screen?

As i'm still on 190 I wouldn't know this, but would it be possible that userdata isn't actually a part of the update app no more?
Seeing as it still works I would assume that is the case.
There’s a user data.app packaged with update.app, just noticed it.
In update.app I’ve got file names 11.cache.img 09.cust.img
Did you have to rename yours?

No because you're going to be picking them via fastboot anyway, I don't believe the name matters.
The ones in the update I used were not named like that IIRC.

Brick - No fastboot - EDL only - Set active slot?

I have not one, but two bricks. I bought one to unbrick the other, but the reverse happened. Using the EDL tool from this forum, I made a full and then an all backup and tried to use it to unbrick the other. No success. Now I cannot enter fastboot on either device, but both will enter EDL. I think at least one will fastboot if I can switch the active a/b slot.
Can the active a/b slot be switched via a command in the edl mode? Or is there another way to switch the active slot on a brick without fastboot access? Thank you
I already had that you have to put in the edl tool Then unlock bootloader and then you can go back to fastboot mode, it is because the files abl.elf have to be flashed to have fastboot
but to avoid the brick you have to flash all then boot the mobile phone and best an official Rom flash then back ...in edl Tool .... if you have an A2020G the 1.6 edl firmware helps you continue flashing and then you can lineage OS and then everything else flash what you want

Thank you for your answer.
I have tried flashing both phones with the following:
1) Full edl from newly purshased phone with v1.1
2) All edl from newly purchased phone with v1.1
3) A2020G v1.6 pro firmware
4) Several other firmwares which the edl would not accept as valid.
None of these worked. Actually, they made things worse. I cannot not even get to fastboot anymore. They both used to give a splash screen that quickly looped. Even that is now gone. Pressing any combination of buttons results in absolutely nothing or edl mode.
The only conclusion that I can make is one of two things:
1) Bricked both all hope
2) edl flashes that I am using are set up for A slot, when the phone is trying to use B slot. I thought when one slot was unbootable it would automatically switch to the other but that doesn't seem to be happening.
Does anyone know of a way to force the phone to boot to the other slot from edl mode? OR some flag that I can edit to switch the slots? OR some command that I can issue to switch slots using fh_loader.exe or emmcdl.exe or another edl tool?
There's no command to switch active slots that I know of and I've gone into the source on fh_loader.
What phone version do you have? Is there some reason you didn't download the EDL tools I uploaded recently instead? The original EDL tool has a few bugs. Read the newer EDL tool thread for some helpful information related to unbricking.
The fact that you aren't getting a ZTE logo at all indicates that you do not have a mixed up slot a/b situation anyway. It probably means you need to fix your AOP files. Of course the original EDL tool doesn't really let you do that. If you have the US version you can use the tools I uploaded to target just the AOP files and try restoring them from your original backup... either the a or b slot one should work.
Make sure you keep your original ALL/FULL backups (both) from the EDL tool, they're probably 99% good and you'll be doing yourself a favor not to delete or modify them.

You can only change the slots if you are in Fastboot. You have doing it wrong ... if you have an A2020G you can flash the firmware ... if you have the A2020u version then you should ... flash the correct one
so in itself quite simple .... flash edl firmware and then unlock .. then you boot into the fastboot mode and then you have to use these lines
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
Then
fastboot --set-active=a
in any case you have to unlock to access the fastboot menu
then you should be able to boot

remember to flash Android 9 edl firmware because otherwise the unlock won't work
---------- Post added at 04:47 PM ---------- Previous post was at 04:39 PM ----------
also remember that some firmwares have to be in the flash folder or in the backup folder if it doesn't work

A2020U on both.
Many thanks for your edl tools! The problem was at least very close to what I thought. Active slot a. Fix bootable partition on your edl tools brought both back to their previous state. (This a/b slot scheme is intentionally over complicated and for modders makes bricks instead of preventing them.) The newly purchased phone is now unlocked and bootable into v1.1. I will proceed with lineage next. The old phone is still a brick with a locked bootloader, but it has fastboot now. I keep you posted. Other life duties call at the moment. Thanks!

It's great to hear I was able to help save from that terrible bricked feeling!
For the 2nd phone - you can try this to unlock it manually without getting it to boot... First do a full backup using my EDL tool. Then use the "FRP" tool I included to write an "unlocked" version of the FRP partition. Then go into fastboot and do the unlock manually - I think it's "fastboot flashing unlock".. but just search to make sure that's right.
Otherwise.. I'm slow but I'll eventually upload the locked stock ROMs.

Both are unlocked now, thank you!
I am still having trouble getting lineage OS to go though. Here's the steps I follow:
1) Fashboot flash twrp from here. https://www.mediafire.com/folder/ha8j5crsdmbmx/ZTE_Axon_10_pro_stuff
2) Fastboot flash vbmeta from here. https://www.mediafire.com/folder/ha8j5crsdmbmx/ZTE_Axon_10_pro_stuff
3) Boot to twrp.
4) Twrp flash lineage 16 OS. Tried both from here. http://samson.nwwn.net/~unjust/Axon 10 Pro/LineageOS/
5) Twrp flash lineage 16 OS root addon arm64 from here. https://download.lineageos.org/extras
6) Wipe data and cache.
This results in the previous state in which only edl, no fastboot is available. So I flash my all backup using the edl tools and I am back to the beginning. I must be missing a step???
EDIT: I also tried restoring aop and uefisecapp files via edl after above steps as suggested in your readme. Same with vbmeta. Again, edl only, no fastboot.

6) Wipe data and cache.
This results in the previous state in which only edl, no fastboot is available. So I flash my all backup using the edl tools and I am back to the beginning. I must be missing a step???
EDIT: I also tried restoring aop and uefisecapp files via edl after above steps as suggested in your readme. Same with vbmeta. Again, edl only, no fastboot.

Just replying real quick since I have a min and I saw a few things you can try... 1. make sure you're installing twrp itself with the zip after you boot into it with fastboot, 2. use the two flags when you write vbmeta just in case (I forget them but one is dm verify and the other is no verity, should be in the original LOS16 thread) and 3. try the fix bootable partition tool from my tools after you install. the LOS16 image has a similar problem as all other images that it has a specific slot it works on (B I think) so if you end up installing and trying to boot it from the other slot it locks into a fast bootloop. Don't bother installing the addons until LOS is booting, so just do a reboot to system after you flash it, fix bootable. If it doesn't boot then it has to be something I'm not thinking of. Goodluck!
It's been a while, but I wanted to follow up.
I did finally get lineage working. The two things that I was missing:
1) Fastboot to flash boot partition with los-twrp-magisked-boot.img
There is another file named twrp-magisked-los-boot.img that did NOT work for.
A third file named Magisk20.3-twrp.img would appear to be yet a third option for flashing boot. I did not try it because I had a working boot.
All three files can be found at link already given: https://www.mediafire.com/folder/ha8j5crsdmbmx/ZTE_Axon_10_pro_stuff
2) Fastboot to flash system partition with system.img
I used python and a python module called payload dumper (use google to find tutorial) to extract the .img files from the lineage 16 zip file.
This gave me 5 files.
boot.img - Did not use. See #1
dtbo.img - Flashing it led to a brick, if I remember right. Do not use.
system.img - Yes!
vendor.img - I flashed it too, but I do not think it is necessary.
vbmeta.img - Did not use. Use vbmeta disabled as noted above.
I use the lineage 16 dated 20191029 that used to be available at the following link. It appears to be dead as of today. Maybe will return.
http://samson.nwwn.net/~unjust/Axon%2010%20Pro/
Other versions of lineage will probably work with this method, but I can not say for sure.
In summary, use fashboot to flash los-twrp-magisked-boot.img and system.img. Obtain boot from link above. Obtain system from python module payload dumper from lineage 16 zip file. See other threads on this forum for details regarding unlocking bootloader with EDL tools and how to make vbmeta disabled. Hope this helps someone avoid the headaches I had!

Thanks a lot! I'm stuck in the same spot, I have the solutions but I can't connect fully with sahara or qpst? Is this why you went with the payload dumper? Sorry I'm unfamiliar but I'm up to use it.

By sahara, you mean the EDL protocol, yes? (I am not familar with qpst.) Are you using the EDL tools published by unjustified and bobthenormal on this forum? I had problems with the sahara protocol too when adding the firehose. I initially fixed it by opening the back case and disconnecting and reconnecting the battery connector. That's a big headache, especially if you don't already have the back case open. (I had it open because I had previously replaced the screen.) I found that to be unnecessary. If you press all three buttons to enter EDL mode, just press them again and again until the sahara works and the firehose goes in.
Regarding payload dumper, I used it simply because nothing else gave me a bootable phone. I did use the EDL tools to unlock the bootloader and to set the active slot (only bobthenormal's EDL tools will set the active slot).
Here's the payload dumper tutorial that worked for me.
Extract Android OTA Payload.bin File using Payload Dumper Tool

Don't forget to flash los-twrp-magisked-boot.img and vbmeta disabled as noted above. Also, if you use this method, let me know if it was necessary for you to flash vendor.img. Above all, do a complete backup via the EDL tools before making any other changes!

Question Bricked with no recovery. Please help

Long story short I messed up and now I don't have recovery. Only fastboot. Was bricked too before the no recovery thing.
How do I try to sort this? I don't have a pc either.
Using my old OnePlus 8T I was able to unlock, root and install a custom kernel.
Any ideas?

the good news is your phone can very likely be fixed. however in my experience you will need a computer. Folks here would love to help but knowing what device you are having an issue with would probably help with response to your situation. from fastboot you can boot a recovery image for your device and go from there. from fastboot you can also likely flash stock firmware to your device and start over fresh. It's also common to have to perform a factory reset after flashing the device to get it to properly boot.

OnePlus 9.
I tried searching but there are so many dead ends for finding the stock recovery. Even with that I'd still be bricked.
Where would one find the stock recovery, kernel and fastboot ready update.zip?
You do realize the boot.img is both recovery and kernel. Just extract it from payload.bin

If only I thought of that. It's not like I've been trying all day without success extracting what I need from the payload.bin. Definitely no dead ends there. Thanks for the massive help.

Im so close I can smell it now. Managed to get Python installed (had to deep dive into the comments on articles and tutorials) and have everything extracted in the last hour.
Now, for flashing these images I have to use Termux and it's working for the most part. My issue is now that I can flash one batch of images but not the other as per the xda guide linked now:
Restore OnePlus 9 to Stock via Fastboot Commands
This guide assumes you have the SDK Platform Tools installed and working, along with USB drivers for your device (if needed), and have your full update zip which you've already extracted the payload.bin from, and then dumped the images using...
forum.xda-developers.com
I keep getting errors about the partition being locked or something.
So close man. So close.
Locked partitions can only be flashed in fastbootd (fastboot reboot fastboot to get there).
First of all... Hold the both volume and power button for around 2 minutes. It'll take you to the bootloader mode. Then from the bootloader mode turn off your device then boot into edl then flash with msm.
Lesson learned

Question Noob who bricked phone trying to root here. Need help.

I didn't know what I was doing and now I'm paying the price (tbf the guides I found weren't very beginner friendly).
I tried installing Magisk on my device. The guides online told me to use a .img file patched by the app and flash it. I did that and now I'm stuck in fastboot mode.
Sorry if I need stuff explained. A lot of this goes over my head and evidence shows that I'm dumb, so bare with me.
You don't flash the boot image or you risk a brick, use fastboot boot boot.img instead. When it boots, open Magisk and do the direct install.
To fix it you'll need to get a stock copy of your boot image and try flashing that or just use the MSM Tool for your device.

You can also find the variant for your particular device and MSM the device back to stock. Easy to do. This is how a OnePlus tech remotely fixes a device without being sent in.

It's a black screen.
Power off device. Hold vol +/- while inserting usb cable. Should be in EDL mode. PC will make a sound or MSM will say "connected".
First off you could always extract the ROM that you're using by downloading ROM and payload.bin dumper, extract pay load takes a long time please wait till the window closes by itself. Make sure your bootloader is unlocked.
reflash the boot.img over your device through fastboot mode with the extracted boot.img.
Make sure you open command prompt inside the folder that contains the fastboot files and adb files to run fastboot in command prompt. Connect your phone in fastboot mode.
/Fastboot flash boot boot.img
Boot.img has to be located within your fastboot files that you have downloaded. Or if you internally installed with platform-tools then use that specified folder and insert your boot.img there. If you do not command prompt won't be able to locate the file and will fail.
If it does not boot after successfully flashing stock boot.img you will have to follow a tutorial to use MSMtool for OnePlus 9. Depending on what firmware you need download appropriate files,. Make a space on your computer for your files because there will be a lot. Or you could also format data and see if that was the problem before considering MSM tool
You need the correct drivers for EDL mode to function correctly, you also may want to install OnePlus drivers from there website.,
For EDL mode to be detected with OnePlus 9 you must download a driver called
Qualcomm HS-USB QDloader 9008
Anymore questions feel free to PM me I may be able to help and same with some of the other guys on here that have also commented above.

Question How to unbrick One Plus Nord CE 2 Lite ?

I have bricked this device (One Plus Nord CE 2 Lite) by flashing the unofficial twrp image for this device. Device bootloops in TWRP.
Previously, I had succesfully unlocked the bootloader and rooted this device by flashing the patched magisk boot.img by following the method mentioned in this post (https://forum.xda-developers.com/t/rooting-oneplus-nord-2-ce-lite.4500297/)
How to restore the factory image and recover from this?
Any help is appreciated.
Thanks
...reboot to fastboot, flash the original boot and vbmeta and you're done ...maybe you have to change back the slot, but it's almost impossible to brick the device
...don't mess around with "Recovery" ...this device has already the newest partitioning system and there is no recovery partition
best regards
I messed up by flashing the wrong twrp image made. (Device was stuck on 1+ logo screen)
Thanks to your post i was able to rescue this device.
I used Oxygen Updater App, payload-dumper-gui and minimal adb fastboot.
Flashed boot and vbmeta with stock img files.
Restarting the device now will boot into fastboot mode.
Changing slots helped a lot.
(fastboot set-active=a/b)
After that, Device booted normally into OS.
... you're very welcome, Sir ...but really, don't mess around with "old school" recovery systems ...they are not needed anymore and furthermore they can't handle the "dynamic super partitioning" ...and again: nobody needs them after the year 2015 anymore
...best regards

Hey can you help me pls, I am in the exact same situation as you but I can't get the stock img files, whenever I use payload-dumper it just gives me system.img and nothing else, could you maybe share your img files ?
Edit: I manged to get some files but still not the boot.img, I don't undestand why it just refuses to give them to me, I redownloaded everything at least 3 times...
Use Payload-Dumper-GUI instead of Payload-Dumper-Go
Hey @NickR01 if possible can you send me an boot.img and vbmeta
I don’t have windows pc so can’t use Payload-Dumper
It will also help future users to unbrick device.

@vikas_anakin I have files for eu variant, can't help you there bud. If flashed it can mess up your device.
If you are stuck with payload.bin extraction... try it with an android device.
Here's the tool for Android.
Payload-Dumper-Android
Here's the guide for it.
XDA Guide
Newb Guide
Follow the guide and download this app to extract the .bin file
Termux App: Termux Github
After the extraction, type fastboot (pc required) commands to flash and change current active slots from A to B if it's stuck in bootloop after flashing.
I hope this helps you recover your device.

Extracting the payload.bin is not an issue, The issue is I don't have stock firmware.
I used https://www.getdroidtips.com/oneplus-nord-ce-2-lite-5g-firmware-flash-file/ but my wifi and Bluetooth are not working after installing it.
Do you have any suggestions on how can i resolve these issues?
@vikas_anakin Download authentic firmware from this app. Files are pulled from OnePlus servers.
Google Playstore: Oxygen Updater
Oxygen Updater Settings -> Enable Advanced Mode
Select device region.
Latest update for holi is CPH2381_11_A.13 as of now.
I extracted the images from the payload.bin found in the Oxygen Updater file (that I had actually successfully used to update my device) and flashed 2 partitions:
fastboot flash vbmeta vbmeta.img
fastboot flash boot boot.img
I then rebooted and now it's stuck in a boot loop & I can't even access fastboot anymore. Can someone please help?
Thanks
EDIT:
I managed to access fastboot & flash the rest of the partitions to fix it.
Hi everyone, just to piggy back on this thread, I also have the same device, and I have unofficial twrp and boot loader unlocked, however I have no back up rom and just want to get the phone back to normal really. Ive been following guides all over the place, but could someone point me in the right direction ? can I just download a rom for the OP nord ce 2 lite 5g, put it on my phone and have twrp install it? could someone guide me please. many thanks!

Or else you can extract img files from the oneplus rom file.
and flash them using fastboot.
Okay thank you for the reply, would you be able to point me to a official img file ? Or maybe someone has one extracted I could use please? I have looked online, but the ones I have gotten don't seem to work. I have also looked on the oneplus website for an official img but I could not find one.
So after a little more research, I can use another android device with the app Oxygen updater, download the full img.... So I am currently doing that and then ill try use fastboot or twrp to flash. Just wanted to spread info incase anyone else is having issues getting latest official roms for this device.
Hey guys, i have bricked my Oneplus Nord ce 2 lite 5g (Cph2381)

Hey man, I would suggest not going with msm tool or anything.
Just download the latest update file of your device using oneplus updater app, or you can ask for the file if some of your friends has the same device.
use this tool to extract payload files https://github.com/vm03/payload_dumper
Now you can follow the same procedure as here https://forum.xda-developers.com/t/...ock-oxygenos-firmware-on-oneplus-10r.4465077/
