Question No valid operating system could be found motorola - Motorola Edge (2021)

I tried to lock the boot loader on my motorola again and when i tried to boot it back up i started getting this error, I tried the smart assistance tool to flash a stockrom update with a valid OS but it gives me an error saying (To avoid damage caused by flashing RSA recommends you go to the customer service for help. I also tried to flash the OS update but my terminal always ends up saying "fastboot: error: cannot determine image filename" Please someone help me.

Have you tried unlocking the bootloader again in fastboot?
If RSA won't flash, you can try doing it by hand or with https://forum.xda-developers.com/t/utility-motoflashpro.4252201/
Sticky on the telegram group https://t.me/MotorolaEdge20 seems to suggest relocking bootloader is straightforward. Just restore stock firmware and relock. https://t.me/MotorolaEdge20
Otherwise, you might need to flash a blankflash first, but best to avoid that if possible.

Flashing stock rom with locked bootloader

Today I was able to flash the stock moto E firmware on my friend's moto E without unlocking the bootloader.
Does this mean the stock recovery identifies official firmware?
Is it possible to do the same on moto g 2015?

Yes. As long as it's factory stock firmware it will flash on a locked bootloader phone.

How does the phone recognize that it's stock firmware? Is there any way to fool it & flash different firmware?

Wow! You're right about it being old. It's been a while since I had the Moto G, but from what I remember, the stock recovery recognized the stock firmware because of it being signed, or something like that. I don't know if it can be fooled.

On a Motorola device with a locked bootloader, fastboot will recognize and allow installation of an official stock firmware package which is the same or a newer build as the firmware last installed on the device. In other words, downgrading is not permitted with a locked bootloader. It's not the stock recovery that is "recognizing" the stock firmware package, but rather the /aboot bootloader partition. Stock recovery recognizes and permits installation of signed OTA update packages, but not entire firmware packages Official firmware packages are installed using fastboot mode or RSD-Lite. As far as "fooling" your device into flashing an otherwise unauthorized firmware package, yes it has been done but is an extremely tedious and risky process. The process involves intentionally hard bricking your Moto device in order to trigger QDLoader_9008 mode. From there, QPST/QFIL is used in conjunction with a firehose program protocol to push the firmware package to the device. This method has been used to root a number of Moto devices that are unsupported for bootloader unlocking. Again, it's rather tedious, complex, and requires a rudimentary understanding of Linux and Python. A locked down bootloader on a Moto device presents a considerable obstacle in the way of rooting, modding and customizing the device. As a good rule of thumb, if you want a Moto device you can easily customize, root, flash, etc., always get a device supported by Motorola's bootloader unlocking portal. Moto devices branded by Verizon, AT&T, Straight Talk & Cricket are notorious for locked down bootloaders. Sprint, Boost Mobile, Virgin Mobile & T-Mobile branded Moto devices are known generally to support bootloader unlocking. And, of course, factory unlocked and developer edition Motorola devices support oem unlocking, rooting and customizing.

@Viva La Android Hello friends ,does that rule apply to other android devices with Stock Firmware,Locked bootloader and Stock recovery as well ?
Does reflashing the same ROM i.e going from stock firmware of an android version and SKU to stock firmware of the same android version and SKU wipe user data ?
Thank you
In general, yes it does. Some manufacturers configure device bootloaders where downgrading is permitted while in a locked state. For example, many MediaTek-based devices can be downgraded via the SP Flash Tool, even with a locked bootloader. And virtually any devices with an Allwinner chipset can likewise be downgraded using proprietary flash tools. But as a general rule, on a bootloader locked device, users are permitted to flash stock factory images.
On Motorola devices, fastboot flashing firmware packages will not result in a loss of data as long as you skip over this command:
fastboot erase userdata
This holds true whether you are flashing the same build or updating the build by flashing a more recent firmware package.

Can you send me a message please? Ineed to ask you about Stock ROM on moto g6 play
This is a link to the official Motorola firmware packages for all carrier and retail variants of the Moto G6 Play (codename: jeter). Be sure to select the correct model number/carrier variant from the list. If your bootloader is locked, choose the most recent build version for your device.

Bootloop, oem, many problems

Hello there,
About year ago I've done an update to 6.0 android. Battery was charged near full and everything seemed okey. But, after update I faced a bootloop. So I tried to flash stock firmware and... failed. Many times. I'm unable to boot into recovery mode. Factory mode also isnt working. So, I tried to unlock my bootloader and flash another image, but when I try to unlock, I get a: "Check allow oem unlock in developer options". Sadly, I cant boot to check this option Is there any way to unlock oem without running android? What can I do? :crying:

How can you flash the /persist partition in a device with a locked bootloader? Doesn't this contain other information as well?
I think the real problem here is either the OP is not using the correct factory firmware image, or incorrect user procedure.

You are probably correct. Even with a locked bootloader, certain partitions can be flashed as long as downgrading is not detected. Example, if I have an xt1548 Moto G3 running on stock 5.1.1 firmware, and I have a locked bootloader, I can flash either an updated 6.0.1 stock firmware package or I can reflash the 5.1.1 firmware with the same build as the one already installed. The bootloader will, however, prevent downgrading. In flashing the /persist partition, the .img being flashed would need to be from an equal or newer build as well.
But again, your statement regarding the correct firmware procedure and/or correct firmware package is likely correct.

You can't flash anything except a bootloader. I was in this situation as MotoJunkie knows and nothing works. I did have a full backup of every partition on the phone and none flashed. Today I bricked it so badly that it doesn't even turn on anymore. My tip is to not mess with the bootloader and stuff and just use the phone normally as many things are encrypted on this phone.

Yes I recall your situation and your hard brick. I'm saying that under normal circumstances you can flash full firmware packages with a locked bootloader, as long as downgrading is not attempted.

You obviously developed corrupt partitions some way or another. I flash stock firmware packages with a locked bootloader on a regular basis. You should always be able to flash the same firmware build that is currently installed on your device.

aw man... well, I meant to post specifically to the last post in the thread but was on the mobile app.
:good::good: Just wanted to say thank you for this post, the links to the image files and the flash-all BAT file. This really saved my butt with a Project Fi Moto X4, which I had rooted using Magisk before checking on the availability of factory firmware images from Motorola. (of course there are not any available from Motorola ) The phone was continuously prompting for an OTA update, which would fail. I first tried the Magisk uninstaller, which ran successfully in TWRP, but the OTA update was still failing. After some digging on Google I found your post and used the Project Fi image to flash the phone, it worked perfectly! There was an OTA update available after flashing (The May 2018 security patches, "28.2") and it installed successfully. I love the Android community, the XDA community, and folks like yourself who take the time to write posts like this. Seriously, thank you!

OnePlus 8T (TMO) KB2007 bricked after LineageOS flash?

Hi, I did something stupid and need some help please.
I got the bootloader unlock code for my KB2007 - Unlock went well, no issues.
Then I proceeded to download and install the latest official TWRP - Also no issues, I was in the custom recovery, created some backups etc.
After that, I followed the instructions to install Lineage OS as posted here:
Install LineageOS on kebab | LineageOS Wiki
wiki.lineageos.org
I flashed the dtbo and vbmeta partitions as instructed and proceeded with adb sideloading the copy-partitions-20220613-signed.zip file - Somewhere around here is where things went south.
I was not able to access/read my data partition anymore, and attempted to flash the lineage-recovery. After a reboot, I'm now stuck in the bootloader (fastboot). When I select Recovery mode, the phone just goes black. I also can no longer "fastboot boot twrp.img" - Error: "Failed to load/authenticate boot image: Load Error".
After checking the guide one more time I noticed it says the device has to be on Android 12, which mine was not (it was still in factory condition - Android 11). So that was likely the problem.
So now the big question is can I recover from this state? If yes, what's the best way to do so?
Thanks so much!

Restore to stock via MSM.
You must update to OxygenOS 12 before installing lineageos 19.1 or you will brick.

Then OTA to OOS 12, then install LOS19.1.
Thanks guys! I was able to restore the device using the MSM tool
I intend to keep it on OOS 11 (and potentially flash LOS18.1), because KB2007 is the T-Mobile variant and based on what I read dual sim only works with OOS 11.
The problem is it is becoming increasingly difficult to find instructions (or even downloads) for anything but the very latest versions :/

The problem is it is becoming increasingly difficult to find instructions (or even downloads) for anything but the very latest versions :/

You can also use KB2007 OOS 13 beta 1 which works with dual sims.

Thanks! Yeah, I also read about that, and it does indeed sound like a potential way to go.
Do you know if anyone has figured out yet what makes this "beta 1" special in that it allows dual sims? I think I also read it's no longer possible with beta 2.

As far as i know, it's still unknown what makes beta 1 work in dual-sim mode.
