I can't flash my Nexus 6

I have been away from Android for a little while - but I'm coming to sell my Nexus 6, and so I'm attempting to flash the latest OS from google.
I downloaded 6.0.1 from google, and then worked through these steps:
fastboot flash bootloader C:/image-shamu-XXXXXX/bootloader.img
fastboot reboot-bootloader
fastboot flash radio C:/image-shamu-XXXXXX/radio.img
fastboot reboot-bootloader
fastboot flash system C:/image-shamu-XXXXXX/system.img
Yes, there are more steps, but I just can't get to them! Once I flash system I get the following...
target reported max download size of 536870912 bytes
sending sparse 'system' (517178 KB)...
OKAY [ 25.080s]
writing 'system'...
OKAY [ 7.142s]
sending sparse 'system' (515137 KB)...
OKAY [ 25.155s]
writing 'system'...
OKAY [ 7.346s]
sending sparse 'system' (515644 KB)...
Thats it, thats as far as it ever goes, then I just sit there waiting, waiting, and nothing happens.
Any suggestions?

Updated Android SDK Tools to make sure you have the latest fastboot? If you haven't updated, update these.
Here's the commands I run, keep in mind this will completely wipe all data/apps/files from the device, so backup anything you want saved to a computer before doing this. Is it overkill? Sure, but I've never had an issues across multiple devices, so since, for me at least, if it isn't broke I'll keep doing this:
Erase:
Code:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
Flash bootloader:
Code:
fastboot flash bootloader "name of bootloader"
fastboot reboot-bootloader
Flash radio:
Code:
fastboot flash radio "name of radio"
fastboot reboot-bootloader
Flash img files:
NOTE: The system.img is large, so if your Android SDK tools isn't updated, you could get an error. This part does take a few minutes to do, so be patient and give it time to complete.
Code:
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cache cache.img
fastboot flash userdata userdata.img
Reboot device:
Code:
fastboot reboot

Just a thought, prompted by the commands in the original post referring to the C: drive. I didn't even know you could do this, though I suppose it makes sense. The easier method IMO is to copy or move all the image files to the ADB/Fastboot folder, rename them if necessary for simpler typing, then just "fastboot flash system system.img", etc., as RMarkwald says.
I doubt that it will make any difference, but since you appear to be stuck it might be worth trying - worst case, it fails again...
And just for curiosity, did you try flash-all.bat? I know that people have trouble with it and fall back on the separate flashing steps - just wondering if that's why you're doing it this way.

Good call on the movement of files to the adb/fastboot folder, as that is what I do when flashing these files, and the flash-all.bat potentially causing his issues.

Having all kinds of trouble rerooting my 6. Will this relock the bootloader? Wanted to keep user data but if a fresh start is what I need then OK. TIA

No, you have to run "fastboot oem lock" to lock the bootloader, not recommended.
You perform above steps, boot device and go through setup, enable USB debugging, boot to bootloader and flash TWRP, boot to TWRP. You will need to clean up some space to flash SuperSU (you'll have to remove apps from /system/app or /system/priv-app), as there will not be any space on /system to install/flash anything that needs to live there, it either won't work or error out. Once you have removed system apps and create space on /system, you can flash your SuperSU zip, then reboot the phone.

I don't wanna relock the bootloader. Not sure what to remove from system apps, etc. This was not this difficult the first time I rooted. Thanks for any and all help.

This is off-topic from the original question, but let's go with it...
Personally I've never had to remove anything from system. Clean install, flash TWRP (or just temporarily boot into it), flash SuperSU v2.67. Job done. Since it (probably) doesn't try to install into system, there shouldn't be any problem.
@dannstarr - you haven't answered my question.

Do I keep system read only in twrp 3.0.0.0?
Disregard, did everything suggested by rmarkwald and dahawthorne. Worked well, took some security update that happened to get rid of the corrupt phone boot message. Flashed twrp 3.0.0.0 and installed SuperSU 2.67 with no problems. Thanks all.

My nexus will not flash correctly

Hello guys, ive been generally lucky in the sense that i have had no issues...until now.
I have tried installing the most recent updates (7.0, and now 7.1.1) and i continue to get this error through cmd. It does not seem to want to flash anything, and i have gotten it to flash, root, and twrp, but it still acted funky. Today, trying to remedy the situation, i attempted to flash the new 7.1.1 update, and return to stock (to later return to power user) but it is still doing it.
It says Bootloader: has-slot (not found), and a couple other things. When i try to flash individual pieces, it does not retain it. when i try to flash the flashall.bat, it flashes but does not flash everything, it will say the stuff has transferred 0 and skips it as it looks like. I cannot get my bootloader off the october one, and i have looked everywhere i can to try to fix this.. please help, its driving me mad. I will be happy to provide any information needed.
Thanks Community! You rock!

Have you tried a different USB cable? A different computer? How about a different USB AND a different computer? I think this would be a good place to start.

Can i ask you why this would matter? My usb seems to work fine, and my computer had no issues before this... i can still perform different actions, and my phone is showing up as ADB and Fastboot.

If it's not pc or usb cable related you can try to flash latest factory image step by step via fastboot without your simcard

Well, you might want to post the complete output of your flashing attempt, but if the bootloader slot isn't found, that's usually a sign of a hardware problem. Hopefully I'm wrong, but until we see more from you, I simply don't have an answer for you.

Ive tried to fastboot everything individually, and it refuses to take. I tried the flashall, same thing. I used NRT and it partially worked, but has sorta the same error. I will be flashing again and providing screenshots right now. I was able to get into a rom, root, twrp but i still cannot update all of those core things (bootloader, radio, and such) Thank you guys for the help. Much needed.

Here is the attempt to just flash the bootloader, i have tried from a different location but this is directly in Platform-Tools of the SDK. As you can also see, it does register under fastboot...

I just tried what you suggest, and im not sure if it worked. It said everything wrote (on twrp) but it was very quickly done. I feel it did the same thing as CMD did.

You could try using the correct Fastboot command...
fastboot flash bootloader bootloader.img
The command is fastboot flash <partition> <image>
Your screenshot says only "fastboot flash image" but doesn't state the partition you're trying to load, hence "unknown partition".
And since we're on the subject, perhaps a repetition of the procedure I used to use before the full OTA days might be useful to you and other people.
Preparation.
- Take a TWRP backup and save it on your PC.
- Download factory image (https://developers.google.com/android/nexus/images#shamu) and unzip all files, including the zip within the zip. Rename the *.img files to the names below. Copy all of them to the same folder as your ADB/fastboot executables.
- Download the relevant TWRP and rename to twrp.img - also put in ADB/fastboot folder.
- Copy SuperSU to device (if root wanted).
- Set USB debugging in Developer options & attach to your PC.
- Open a CMD window, navigate to your ADB folder, and check connectivity with "adb devices". If it's ok, copy & paste each command below into the CMD window and run them - the only lengthy one is the system.img.
1. adb reboot bootloader
2. fastboot flash bootloader bootloader.img
3. fastboot reboot-bootloader
4. fastboot flash radio radio.img

Can you give a bit more detail? So the phone is crashing, but is it now on the version that you wanted to have (7.0, 7.1.1)? There is rarely such a thing as "too much information".

Ok, so what happens is that it says i am on 7.1.1 with i guess the related info, but it does not load in properly as you can see with the screenshots. I start up the initial setup, and i can get through most of it fine, but some areas *permissions* are all blotchy. like i can toggle them on to submit data but i cant see what it is exactly im agreeing to. Then i start the phone, Google App automatically crashes, along side system ui. When i updated them, it seemed to fix the problem. But the issue is, i am not receiving phone calls and texts until possibly days later, and when i send texts it says "sending" and proceeds to spam the hell outta whoever its going to (sends literally 30+ texts). When i call someone, my phones Do Not Disturb mode gets enabled, and then nicely cuts out my audio. I can turn this feature off when im in the call, but sometimes it will then glitch the phone app, and i cannot essentially "hangup". My phone also now dies at 9%, where it had not previously (when i was on other rom / older stock) This all started after i updated to the october patch, and i noticed in december that i didnt have the december patch / update. I went to install it, and the same exact thing occurred. Ive attempted a rescue ota, and a sideload ota, and now this stuff as well, but i fear the worst for my phone. Let me know if i need to add anything else

Strephon may be right in suggesting a hardware fault, but equally it may just be that your phone is now somehow corrupted. My only suggestion is that you nuke it - factory reset, TWRP, wipe everything again in TWRP, and then try installing from fresh using the 7.1.1 full (not OTA) image and the instructions I posted earlier. If it still doesn't work I'm out of ideas, but there are people with far greater experience here than I have, so don't give up. It's too nice a device to just write off.

That's a new feature of 7.1.1. So you won't have to listen to notifications while on the phone. It's disabled as soon as the phone call is over.

[ROM][STOCK][FASTBOOT][OP6T] Stock Fastboot ROMs for OnePlus 6T

Things are changing with the advent of project treble and seamless updates. OnePlus will no longer release ROMs flashable via recovery (either stock or twrp) because is no more needed. The updates will be done on the slot not used for example if you are using slot a the update will be installed on slot b and the slot b will be set as default. If you brick and you are in bootloop how you can restore the rom? You can't with Stock ROM you have, because the zip can be only installed via Update Engine, so what can you do? Flash a stock rom via fastboot. I have extracted all images from the stock zip and i have made a new zip with the Fastboot ROM with a flash-all.bat included. This will work only if your bootloader is unlocked. This will erase all your data and will wipe your internal storage.
HOW TO FLASH
This version is only for not branded devices
Download the zip;
Unpack the zip in a folder;
Reboot the OnePlus 6T in fastboot mode (Power and volume-);
Connect the OnePlus 6T to PC;
Run flash-all.bat flasher you need;
Wait until the process end;
The phone will automatically reboot.
FLASHER ADVANCED GUIDE
flash-all-partitions-fastboot.bat : this .bat will flash all possible partitions through fastboot (Except persist) , there are some criticals partitions that can't be flashed through fastboot;
flash-only-persist.bat : this .bat will flash only persist partition in fastboot mode (This is good for people that have problems with sensor);
flash-all-partitions-recovery-criticals.bat : this .bat will boot the twrp and will flash criticals partitions, use this carefully;
flash-system-boot-vendor.bat : this .bat is the same of older flash-all.bat and so it will flash only vendor, system and boot;
flash-all-partitions.bat : this .bat will run flash-all-partitions-fastboot.bat , then flash-only-persist.bat and then flash-all-partitions-recovery-criticals.bat .
Now usually the one needed is only the first "flash-all-partitions-fastboot.bat" but if you are badly bricked i recommend to use flash-all-partitions.bat .

Great work, thx

This is great work. Thanks!

Would it be wise to extract the zip to the 6T prior to rooting just in case something goes wrong?

Right.
So before rooting the device, would it be good to copy the images from this zip to a dir on the 6T in case something goes wrong with the rooting process? For example if Magisk or TWRP mess something up, and the 6T is in a bootloop.
Or are the images in the zip only for flashing from your PC to the 6T? So it would be of no use to have the images sitting on the 6T as a backup.

Hello. after flashing with flash-all.bat, my 6T just boots to the bootloader unlocked warning and stays there. I don't know what to do next.
EDIT: Nevermind, after trying again it worked.

Actually there is not a twrp that support decryption so if you also have the images on the phone you can't flash it in twrp mode. At this moment these roms can be only flashed through fastboot with a pc

After using flash-all.bat I'm getting the "Your device is corrupt" red error message on boot. I can skip by pressing power twice and phone boots normally.
I see people with 6 had to use MSM download tool to get rid of the error.
Is there any solution for 6T?

thank you thank you thank you OP! Nearly bricked my phone while trying to install root (something got messed up with TWRP) and I couldn't even get out of bootloader into recovery. I just got my phone a few hours ago, that would have been sad

Just for the sake of your sanity in the future, if you can get to bootloader and device files are available, you can always get it up and running. I learned that very quickly way back in the day

After using flash-all.bat I'm getting the "Your device is corrupt" red error message on boot. I can skip by pressing power twice and phone boots normally.
I see people with 6 had to use MSM download tool to get rid of the error.

Branded version are different, they have a particoular partitions for volte, i think the only.method to solve your problem is to find another person with the same branded device and make a partitions backup that you can restore

[GUIDE][HOW TO] Flashing with care & Surviving soft bricks with fastboot [CMD] [TIPS]

[GUIDE][HOW TO] Flashing with care & Surviving soft bricks with fastboot [CMD] [TIPS]
Hello guys, some of us are new to the A/B partitions. Flashing on wrong partition may end up in soft bricks. This is not a rooting guide, here I'm explaining how to handle flashing A/B partitions properly and survive soft bricks using fastboot . Always backup your data before flashing anything.
Those who still don't know about the A/B partitions, please take a look at this thread https://forum.xda-developers.com/oneplus-6/how-to/guide-noobs-guide-to-b-partitions-op6-t3816123
Prerequisites:
OnePlus 6T with unlocked or locked bootloader
A computer for running fastboot commands
You :laugh:
Rebooting
Rebooting your device via adb and fastboot
Code:
adb reboot //normal reboot
adb reboot recovery //reboot to recovery
adb reboot bootloader //reboot to fastboot (bootloader)
Code:
fastboot reboot //normal reboot
fastboot reboot bootloader //reboot to fastboot (bootloader)
Unlocking the Bootloader
Bootloader can be unlocked via fastboot
Code:
fastboot oem unlock
WARNING THIS WILL WIPE YOUR DATA
Working with A/B Partitions
There are two boot partitions on this device, named boot_a and boot_b respectively, they are not the “traditional” boot partitions. Both of these partitions contain a kernel and ramdisk like you are probably used to. The difference is that there is no recovery partition and the boot partition is new recovery partition. The A/B partitioning scheme can be quite confusing to users. There are actually two copies of many of the partitions. There is only one data (userdata) partition.
Slots
The concept of ‘slots’ comes into play to determine whether you are booting ‘slot A’ or ‘slot B’. We can determine which slot is ‘active’ or marked for booting via adb and fastboot:
Code:
adb shell getprop ro.boot.slot_suffix
Code:
fastboot getvar current-slot
Switching Slots
We can switch between slots via fastboot:
Code:
fastboot set_active other //switch to inactive slot
Code:
fastboot set_active (a or b) //switch to specified slot
Flashing/Booting
We can flash/boot (temporary flash) recovery/kernel via fastboot. To boot (what we call temporary flash) a kernel/recovery there is no need to switch/select any slot. Keep in mind that when we run the flash command instead of boot, it will wipe the specified partiton (you may lose your root & custom kernel)
Code:
fastboot boot boot.img or twrp_recovery.img
To flash permanently, first switch/select any slot you want or it will automatically flashed to the active slot. This may cause boot loop, always proceed with caution.
Code:
fastboot flash boot boot.img or twrp_recovery.img
Code:
fastboot flash recovery twrp_recovery.img
If your testing something, always use the inactive slot. Eg: if you want to test a custom rom, first back up your data then switch to the inactive slot and flash the custom rom, this will save your time (no need restore full backup only data).
Surviving Soft Bricks
Some possible simple solution we can try rather than using MSMTool or flashing the full rom.
When causing boot loops, try these:
Flash Magisk via recovery
Switch to the other slot via fastboot
Wipe data partiton via fastboot -w
When causing Bootloader crash, try these:
Turn off the phone by holding the power button (release after power off)
Hold both volume buttons
Now press power button
Phone will boot to fastboot
Now switch the other slot via fastboot
To be continued....

Just in case

This is my first A/B device so forgive my ignorance, I was wondering if its possible to flash two different roms on to different slots...like oxygen on one partition and lineage on other?
Also why twrp has two buttons 'slot a' and 'slot b' in reboot section?
The phone doesn't have recovery partition, so what happens on typing 'Fastboot flash recovery' command?

Thanks again for this tutorials. That's really helpful in understanding of the new Android features.
What'd be your advice on instructions to get stock kernel back? I couldn't find an appropriate command on how to do it

You can install any rom on both slot, there is no problem. There is only one userdata partiton. The two buttons are for switching between slots, if you press slot a button, the recovery will mark slot a as bootable or active partition. On next boot or reboot rom from slot a will boot, this same thing is applied for slot b too. There is no dedicated partition for recovery , files for recovery are stored in system_root.

Thanks for the reply. Cleared all my doubts.

So could we have two ROMs and switch back and forth between on one device in this case?

Because of one userdata partition, there will be some issues. If wipe data when switching roms, no issues then.

Man i could use some help patched the file moved it to harddrive tried fastboot flash boot boot.img (the patched one) and all i get is
C:\Users\seang\OneDrive\Desktop\Moto G Stylus 2021>fastboot flash boot boot.img
error: cannot open 'boot.img' Could you please make a guide with some pics or at least a step by step cause nothing i have tried has gotten root yet. Thanks!

Thanks to the OP.

[SOLVED] Flash image as "System"

I'm trying to flash an image as system
But OrangeFox, PBRB and TWRP don't let me (it doesn't even show me the option)
Is there any other way to do that?

Hi @ax0 what do you mean? Flashing from recovery gives the zip access to all system files...

Yeah but I wanna flash a GSI (.img) and when I select the IMG , on the flash menu there isnt no "System"
Should I try to rename the image to "system.img" and then zip it and perhaps flash that?

is there an "install image" at the bottom of the screen in the zip select screen? Are you on the latest TWRP?

Ig he is saying that there is no system partition to flash the GSI image to.
Redmi 9C device has system-as-root partition, meaning that it has Super partition (which is IIRC a combination of system, product and vendor) rather than System partition

All devices shipped with Android 9 must have a system-as-root (SAR) layout. But it's not the same as a super partition.
The SAR configuration merged the root file system into system.img and then mount system.img as the root file system (rootfs).
This was published in connection with "Project Treble" to optimize the update process for vendor related files. Those files are no longer part of /system and now stored on /vendor.
Super: Here the partitions /system, /vendor and /product are dynamic logical partitions within /super (block device) and are managed in userspace. Fastboot access is also handled in userspace (recovery) by the fastbootd mode (fastboot reboot fastboot).

As mentioned before that's related to /super. Use
Code:
fastboot reboot fastboot
when in fastboot mode to switch into fastbootd mode.
Then you should be able to run
Code:
fastboot flash system <PATH TO IMAGE>
To switch back into bootloader mode use
Code:
fastboot reboot bootloader
Take care using a newer version of the Platform Tools for full support of fastbootd mode.

For some reason when I run fastboot reboot (partition) it always just shows me the usage menu!
No matter what the partition is!

can you try getting fastboot through nexustools? I've had tons of problems with 15-second ADB in the past

What is NexusTools?
oh nvm https://github.com/corbindavenport/nexus-tools

that... actually worked!
i can reboot to fastbootd!
and WoKoschekk's guide worked!
thanks yall!
