Hello everyone,
I've recently unlocked my Honor 6A pro boot and since then, I have this annoying message appears every time I turn on my device tells me that my device is unlocked and not trusted. I tried everything to relock the boot again but I failed. It seems that I have to reflash the boot I'm going again to get rid of this message.
The problem is that I don't have a stock boot image and I can't find it anywhere !!
Could any one help me please to re-lock the boot again ?
Note:
Device is rooted and I can't un-root it neither.
Thanks in advance
Any ideas please ??

If Fastboot works, this means your phone is not bricked.
Just make sure your bootloader isn't relocked.
Then flash stock rom 12.5.1 using MiFlash, better than CMD command. You get to see errors in Miflash.
If it fails, then change USB port in your PC. ( USB ports on the back are recommended)
Good luck.

Dude we don't speak German you would have to use Google translate to tell us what it says in English. What did you do to your Poco f3 that bricked it? Do you have an unlocked bootloader? Because it looks to me like 20 threads a day are created for this phone by people who aren't actually into development but just want help, which is fine but it's not what xda is for.

You want to keep it as a secret while using someone else's work?
Guys, just follow the guide here:

I paid $8.00 for a carrier unlock via remote TeamViewer on eBay. I asked if he could unlock the bootloader as well. Everything went well. I used the magisk boot.img posted somewhere on here to flash for root. So far everything working well. I pass safetynet but no luck with GPay.

I'm going to borrow this for my guide. I'll give you credit. Mine works. So weird, two identical phones, one I patched the zipped img, the other I unpacked the img and patched. One will not work for the other and vice versa and I have no idea why. It seems to be the exact same device. But I've had two people brick and need recovery and maybe this could make it easier. Thanks. Hope you don't mind. Check out my guide: do you know an easier way to flash stock ROM? I haven't yet ported twrp. I returned mine to stock and sold them both today and I'm going to take a break

I have the scatter for 6833 if anyone needs it. File enclosed as well as a few other tools and files I needed to root my revvl 6 5g, you should be able to do the rest on your own. Make sure when you are using mtkclient that you back up your preloader above all things in case you mess up. Your scatter will save your hide as well. I've also enclosed mtkclient bypass tool and the 6833 payload you will need as well. Good luck, and credit to Hovatek, and bkerley for their respective tools. If using sp flash tool use the enclosed scatter and the DA_allinone file for the other.

Hey, I'm trying to complete a guide for the revvl v+ 5g. Other people are reporting issues and we're trying to resolve it. We could use your help over here https://forum.xda-developers.com/t/root-flash-stock.4541841/ thanks in advance. Btw, I have that scatter already. It was weird how I got it, though. I found the source code somewhere, I just copied the text and removed the quotation marks and saved it in notepad. Spflash gave me trouble and I had to tinker with some things and bypass DA. But it worked. I thought it'd work for everybody, but now spflash isn't working for some folks, but then we found the newest version. It's not on the official site :/ but now some folks can't get back to stock even with correct files and firmware. I have at least 3 guys dead in the water. Any help would be appreciated. I know you have a life and all, but if you get the time

I don't know how much I can help; I'm little more than an amateur with an engineer type of learning capability and a tenacious drive. I suck at teaching, but will take a look at the thread anyway, because on the way to rooting a treble based a/b partition with tamper evident ro.props, plus having bricked my device 9 ways to Sunday, there's some possibility of being able to offer some assistance. See you there man.

Hey all,
My phone has an issue where it's stuck on target IN, but I discovered with the help of retryfail that the target ID is in the param.bin partition. Does anyone have a param.bin they can dump from their phone using EDL or something? This would help me get back to stock.
Thank you,

I'd like the as well if anyone has it for LE2127 TMO c.22 firmware. But if you use a modded msm tool to accommodate the IN TargetID wouldn't the param img get written over and get you back to stock?
If I borrow my wife's phone long enough, I can get it. She has the same LE2127 9 Pro....
Here you go....
if it works, let me know and include the steps you took....please!
Hi all,
In order to use the file, unlock bootloader, then reboot to fastbootd. From fastbootd, run "fastboot flash param param.bin". You will be able to run stock TMO MSM after this. It doesn't really matter what FW version you are on, you can flash it anyway as long as it's a TMO device.

You'll need to generate new unlock token after you flash this, otherwise you won't be able to unlock bootloader.

Also, while you're at it, is it possible for you to retrieve persist.img as well? I think mine broke, not allowing for use of FP sensor.
Oh my god. I've been dealing with this stupid indian thing for months, I gave up on trying anymore. No matter what I did , I could never get a normal UNMODDED TMobile msm to run for me.
But I got it now.
Followed the steps above. Unlocked bootloader, went into fastbootd and flashed the param.bin from above, and immediately after that I shut the phone off right from fastbootd mode. Started my TMobile msm tool , plugged it in and we are good!
I'm shocked at how easy of a solution this was, I was trying so many other long drawn out trial and errors and it was truly this easy

I encourage you to make a new How-To thread in this forum with instructions on how to fix the target IN problem. There are a quite a few people who are stuck on IN after using the Indian MSM tool. I saw it being asked a bit in the OnePlus telegram group a few months back too. Good work.
It's one more thing off the list for us to have complete control of our device. Since we have the last "real" OnePlus phone with msm tool, the development on this device may go on for a long, long time
Sorry guys, I pulled my param.bin file because deep inside some settings my wife's name was on my phone. I used her param.bin because it was pure TMO... Personal reasons and security reasons as well... hope y'all understand. and as it is I have now gone with flashing my phone to global...... i actually like it better. Got away from a branded phone!

At least we know it's possible now. Do you think we need a pure virgin new in box param or do you think there are specifics to the device and that's why he ( @razercortex ) needed persist also? (I was under the impression that persist was device specific)
I also understand your reservations @razercortex, I suppose we can point people here when it comes up, they can read the thread and understand the risks. I'm not stuck on IN but I knew it was possible to undo something the msm package did and I'm glad to see @TheGhost1951 was finally able to undo it. I knew he felt the same way about undoing whatever was done by the IN msm. Maybe someone can piece together a custom repair msm using a virgin param...but maybe I'm getting ahead of myself
I tried downgrading my Moto G30 from Android 12 to Android 11 using an available stock ROM I found on the internet. At first, I faced some problems and a soft brick, but finally, I was able to flash and boot it correctly. Then, knowing that the ROM flashed was "stock," I decided to relock the bootloader, which was a mistake. After rebooting, I got the message "No valid operating system could be found. The device will not boot."
I spent the whole day trying to figure out how to get it working again. The main problem here is that I relocked the bootloader and can't get to the OS again to enable the option in developer settings to re-unlock it and flash another ROM. I tried using RSA (LMSA) to restore it, but it refuses, and I think it gets the same error that won't let me flash anything to the phone.
During my research, I found that one possible solution is to boot in EDL mode and flash everything again, but I don't want to open my phone and do weird things to get into that mode. Hopefully, there's another solution or another way to get into EDL.
If you have any information that could help me solve this, please comment.
I had the same problem with mine. The thing is, i tried to flash a blank-flash image but it wont go. I think its to early to downgrade your Moto G30, but you can try to flash the stock image in EDL Mode by opening your Motorola. Also you might need to send it to Motorola. Sorry
In the image you have the EDL Test Point you must brick.

Don't you need to just blankflash it in EDL?
And yes you most likely need to open it.
For the Blankflash you need to download Lenovo Rescue and Smart Assistant (since lenovo produces moto phones). What this does it installs the correct drivers for your phone.
And the files can be found here : https://mirrors.lolinet.com/firmware/motorola/caprip/blankflash/
Good luck and as always, do your own research!

I think you can flash with Lenovo Rescue and Smart Assistant or manually, the XML is to flash automatically, you can flash manually each image.
If you cant maybe there is an error along the way.

This might be a complete brick because of the downgrade from what I've read.
There is little info on the forum about this issue so I don't want to make wrong suggestions until i can test.
Yes, unfortunately, there is still little information about the Moto G30. But I hope that there will be more information and solutions in the future.

Maybe you can help me with some info i am interested in.
1.You have booted into EDL using Short Pin method
2.You have used blankflash successfully
3.Then you try to flash manually and got Permission Denied?
For both Android 11 Stock ROM and Android 12 Stock Rom?
EDIT: Is the back of the phone glued? Or just clamps so you can put it back with no glue?
Since i want to test this soon hopefully.

2. I used a blankflash successfully.
3. Then in fastboot tried to flash the android 11 stock and after it failed the android 12 stock image. Also i tried the RSA varient. Both will not work.
The back is clicked in place. There are two stickers on the phone. Two white ones, One on the top left corner and one on the bottom of the phone.
But careful when you open the back. The screws are well screwed and the cap over the motherboard is slightly stuck. Maybe this will help you: Dissasembly Moto G30 YouTube
