Stuck in Fastboot/No Download Mode

Hey guys !
So since i messed up with the recovery mode, i'm stucked in the fastboot with no Download mode (recovery doesnt work neither).
So after searching 3 days in the internet i found the acces to fast through adb by puting a new laf.img in order to restore the download mode and flash a stock firmware !
My problem is that when i try to enter the command on the cmd, i get severals errors, take a look :
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>adb devices
adb server is out of date. killing...
* daemon started successfully *
List of devices attached
C:\Program Files (x86)\Minimal ADB and Fastboot>adb shell

OKAY [ 0.581s]
writing 'laf'...
FAILED (remote: flash write failure)
finished. total time: 5.615s
Also command : "fastboot boot laf.img" result to "Failed(remote: dtb not found) instead of flash write failure..
Of course i have my G3 855 32GB in download mode (but it goes into fastmode), so when i try a command, lines are added in the screen etc..
Does that mean that my laf.img don't work? I assumed that so i try several, but does it have to be the exact same one as the one who was in my phone before( v20a if i record correctly ) or could it be from any 855 32GB version ?
I also thought it could be a recognition problem as when i type "adb devices" or "adb shell" nothing is found..
If someone has any clue or a link to some guide i'll be more than joyful, thanks in advance !

Try adb fastboot when writing command hope it helps

Hey thank you so much for answering !
What do you mean by that, i already download the adb/fastboot driver and launch a cmd in the directory they are at, writing "adb fastboot" has no result neither, can you be more specific please ?

cm13 recently messed up my phone in exactly the same way, no recovery and download mode would jump straght to fastboot. I followed this guide to the letter and am now back running again: http://open-freax.fr/guide-unbrick-your-lg-g3/

Well i hope my problem can be solved in a safer way, i dont like much to go on the hardware part, so I'll use it as my last hope, but thanks
Altought i think my device is recognized by fastboot in someway because it responds when i type commands in fastboot, and also when i reboot it.
But i'm getting this error :
Code:
error : command never completed
error : auto CMD12 error
error : command completed with errors
error : command timeout error
failed to send stop command
failed writing block @ 1
in the screen of my phone. Does that stand for Cyanogen mode which i was trying to put on my phone ?

I mean when you enter command in cmd use adb before any command also use cmd which one available on android sdk folder....also you can use this method if adb not workinhg properly http://forum.xda-developers.com/lg-g...-9008-t3072091

Oh ok ! Also your link is not working :s
I understand that the method can work but I think that the method i'm trying to use is really close to succeed, over my search on the internet, i saw lots of people who manage to succeed with it.
But i guess i must do something wrong. I downloaded the kdz file according to my IMEI.
Then I extracted the .dz file with LG Firmware Extract. Then I extracted the file named laf_393216.bin from the dz file. Changed his name into laf.img , put it into the fastboot directory.
Then i typed
Code:
fastboot format cache
fastboot erase laf
fastboot flash laf laf.img
in a cmd from the directory.
It all seemed to work, but then when i remove the battery and restart into download mode, it goes into fastboot after the download mode charging animation..
Also when i try to boot with fastboot boot laf.img i get the error (remote: dtb not found) on the cmd.
And ERROR: Unable to find suitable device tree for device(194/0x0001001/112/0) ERROR: getting device tree adress failed DTB offset is incorrect, kernel image does not have appended DTB)
Am I doing something wrong, should I changed more file than just laf ?

I don´t know what exactly is the problem, maybe something with your win-driver, some crashed or drifted partitions or some broken files...
I just can repeat my advice: I was in the same situation with my phone after a failed cm13 update and i was trying and reading about 2 days how to solve it - after the above mentioned method, your phone would get out of this "coma".
Maybe somebody else here in this forum could help you with your mentioned method, sorry.

Well I think i'm still under warranty, so i dont wanna touch to much on the hardware.
So do you think, if i send it back without touching anything, saying i put it on charge one night and the next morning it was like this, the warranty could work?

If they found it's rooted or they understand you did something with your software your warrenty is void ?

Remove the battery, put it, press the volume + and connect to PC USB, if like entering download, what happens to us not to go, will leave the ****ing LoGo, Well, hold down the volume + and not let go, I think it is less for 2 minutes more. After a while, the computer tells us that something was connected, the phone will tell you who is in fastboot as I said before, if not let me fastboot flash boot files and the LAF, recovery ect, nothing happens, there is still a magic command.
fastboot boot laf.img
Keep it in the ****ing heart

You have several options:
- find your phone firmware, extract recovery.img and flash it back through fastboot(do exactly the same for the LAF partition to restore download mode)
- flash a custom recovery for your phone model, if it doesn't work try an older version of TWRP, also it can be that your phone is not d855 but d850 model, so try to flash a d850 custom recovery and see if it works(that was exactly my problem and why i got stuck in fastboot mode, because my phone is d850 model and in settings it says d855, so I flashed wrong TWRP)

It seems that your phone's bootloader is locked, you can try to execute this command: "fastboot oem unlock", and then check state with "fastboot oem device-info". But some people says that it does nothing, so you can try and check for yourself.
You can also try to boot directly an image from fastboot for eaxmple:
Code:
fastboot boot laf.img
or
Code:
fastboot boot twrp.img
So if you could successfully boot a laf image you would be able to access download mode, and if you could boot a custom recowery then you could access ADB and to try to flash other partitions, or even flash a custom rom...

Did you unlock your device first with "fastboot oem unlock"?

Yes i did this before, i was running on Remix OS

I don't know if this is of relevance but there were new fastboot commands introduced from Android M (?) and I have recollection about "partial unlock" - two flags required to be set and if only one was set it could be reported that the bootloader was unlocked but fastboot saw it as locked. Above may be totally wrong.
Here's the difference between old and current fastboot commands. Note the new lock/unlock commands
Code:

Hi, I'm just wondering if you were able to fix your tablet. I ran into the same problem as you here and am not able to find a solution to it.

Hi !!
Sorry for bad news, but i didn't found any solution since my Pixel C was bricked. Maybe there is a solution, but I dropped it before finding it.
I hope you find something to fix it !

@viii_xvi Are you using "Minimal ADB and Fastboot" as shown in the post you quoted by -Yazh- ? The current (?) version that I can find is 1.4.3 and that looks to be "2015".
For the current versions of adb and fastboot and the revision history, 12 since October 2016, see https://developer.android.com/studio/releases/platform-tools.html

No. I used the 15 second ADB and Fastboot installer. I'm pretty sure it works fine as I can use fastboot commands.

There are Youtube videos on installing Android Platform Tools and a web search for installing Android Platform Tools with your o/s will find many hits. You need to know you are installing just the platform tools - some of the guides assume you are installing or have installed the full Android Software Development Kit (SDK).
Assuming you are using Windows then the simplest method is to copy the contents of the zip file into the current location of your "15 second" files. This ensures that you can run the new version of fastboot with the folder path you have used previously. In file manager "find" fastboot.exe and that will give you the folder to unzip ALL of the platform tools files. You will know if you have done it correctly if you get requests to overwrite existing files when you unzip the files.

I've followed the instructions so I'm confident I did it correctly. Despite this, nothing has improved. I still can't flash the stock ROM or a custom recovery in fastboot.
What I've noticed from updating the fastboot version are some new commands I found when I entered "fastboot -h"
Code:
fastboot -h
commands:
reboot [bootloader|emergency]
stage <infile>
get_staged <outfile>
options:
--skip-secondary
--skip-reboot
--disable-verity
--disable-verification
--unbuffered
--version
From what I've tried, all the commands in options returns

Hi, Did you tried to flash with the oldest stock rom of the pixel C ? Because it uses older version of fastboot so maybe it will work. I has also the same problem as you but hopefully twrp still worked so i could flash another system image.

I have now tried to flash the earliest factory image and am disappointed to say the bootloader did not flash and so I wasn't able to complete the flashing.
I don't think the problem is the fastboot version. It may be the bootloader itself. I've read someone describe this problem as "Broken fastboot (bootloader) security." I think the problem is that, when unlocked, the bootloader would return the same messages as if it was locked. The security of the bootloader still thinks it's locked and not allow flashing of any images. Also that locking and reunlocking does not improve the situation. This would explain why, when bootloader is unlocked, I get "remote: unsupported command" and "remote: image verification failed", the same as when I try the same commands when the bootloader is locked.

I got a same problem,cant flash anything but ordinary using.
I got the problem caused by flashed twrp3.2.3,cant get into system,just always get into twrp.
cant flash any official firmware with "flash-all.bat",no matter which platform tool or firmware.but the twrp were installed before can flash anything.
finally,I flashed newest OTA firmware,then device can be booted. but got the unsupported command

I'm assuming you have the latest version of TWRP installed. IIRC, there should be "Fix Fastboot" in advanced options. If indeed you have the same problem I had, pressing this should fix the problem. I don't know anything beyond this as I never got to find out what happens afterwards.

I believe I'm not qualified to help you as I disposed of my tablet months ago. All the advice I've given is off of memory and may not be accurate. That being said, I won't help you anymore in fear of giving inaccurate information that may lead to bricking of your tablet.

I have a pixel C, flashed with latest 3-rd pixel experience before, someday i tried to flash back to factory image, hit the same trouble like this topic, i came here several times before, no solution, today, i found another article about this , it's solved my trouble.
sorry i am new here, i couldn't share the outside article link.
would like to share what i did on my pixel c.
1. root your pixel c
2. adb shell //this command could be executed under recovery mode too.
3. su
4. fwtool vbnv write dev_boot_fastboot_full_cap 1
5. adb reboot fastboot
then you could flash anything you want.

I had this just now - I finally got fed up of my Pixel C being so laggy and also chrome opening up as blank pages (I switched to brace to fix this, but it's abit crashy).
Anyhow I found that after
adb reboot bootloader
that
fastboot flash recovery twrp.img
was failing for me in the "Writing" stage
I discovered that the fix was to use
adb flashing unlock
then it will ask you a question (power button to confirm and one of teh volume keys to cancel).
after this it spins with erasing for a while and then comes back to fastboot after which
fastboot flash recovery twrp.img
Worked, after this you get an annoying 30s delay for each restart, I think that can be fixed by
adb flashing lock
I'll verify this when I've finished flashing a usable ROM to my Pixel C...

device unable to boot Error - mdtp image is corrupted

Hi there,
I have a problem i was try to root my phone.
Now i dont have access to ADB but only fastboot works.
If i start my phone it goes on fastboot mode, and if i try "fast boot twrp-3.3.0-0-daisy.img" i get the error "device unable to boot Error - mdtp image is corrupted"
Can some one help me out, if tried to download the image again but without success..

You don't need twrp for root?!
I guess you need to get a fast boot ROM and flash it. Don't relock the bootloader. Don't flash data. Just all the other partitions.
Maybe even just flash that partition. My phone has a and b. Should just need to flash the current one.

fastboot flash mdtp_a mdtp.img
That file is in the images folder after you extract the fastboot ROM.

Hi,
while having 15 years of Linux experience, I've just dropped into the same issue on my first hour of Android exploration. Currently no OS is installed and the phone boots into fastboot. Booting into twrp-3.3.1-dees_troy-daisy.img failes also with "Error - mdtp image is corrupted".
I've flashed mdtp.img from V10.0.12.0.PDLMIXM as described, but still I get the same error when booting into twrp-3.3.1-dees_troy-daisy.img . Is there somewere a documentation, how to proceed in such a case?

I've flashed mdtp.img from V10.0.12.0.PDLMIXM as described, but still I get the same error when booting into twrp-3.3.1-dees_troy-daisy.img . Is there somewere a documentation, how to proceed in such a case?

No OS installed is maybe cause the last rom that you flashed was not flashed in the right slot or correctly flashed.
Also the fastboot command mentioned here is to flash mdtp in "a" slot but you have to see first which is your active slot and then install it on it.

I've searched more for the reason and once got the response: FAILED (remote: partition table doesn't exist)
So it sounds I have to recreate the partition table. I haven't found any fastboot command to request the current partition status.

I don´t think that exist a command to diagnose status of partitions but I´m sure that if you try to flash on an inactive slot then won´t work, ever an inactive slot will give you a fail.
Check your active slot by typing
Code:
fastboot getvar current-slot
and then flash it on the active slot using "mdtp_a" or "mdtp_b" but ONLY if the active slot is actually with all the system on it it´s mean that if you deleted all your system and any of both are actually with partitions running (no matter that with errors) then won´t work this way as you expect.

I have the same problem, what you have did to fix? please

Hi,
I've downloaded and flashed the factory image from miui.com. This way I have reset all my efforts and started all over. You find there the full rom and a flashing guide for the Xiaomi Mi A2 Lite.

Why do you want to flash the bootloader, what is the issue?

Hi @SubwayChamp
I wanted to flash LO16
Did a wpie data -yes format
Then a wipe system as instructed and now im stuck in fast boot.
Device unable to boot. Error - mdtp is corrupted

If your issue is related with mdtp partition then you should to install again this image through fastboot in both slots in order to can boot device again to recovery; use
Code:
fastboot flash mdtp_a mdtp.img
and
Code:
fastboot flash mdtp_b mdtp.img
(you will get the images from any of the full fastboot roms)
From there try again the steps recommended by OP in that thread to get that your device boots on LOS but this is other question concerning only to that thread

Thanks SubwayChamp,
Will try as advised and keep you updated.
I m going to look for the fastboot rom for my daisy.

@SubwayChamp
dit it and when I
Code:
fastboot reboot
it boots straight back to fastboot.
What next? Mi a2 Lite stuck at Fastboot - No recovery, no nothing! Help ?
Thanks for your help!
[EDIT]
realised I can
Code:
fastboot boot twrp-daisy-3.3.1-0-offain.img
and I can flash the twrp-installer-daisy-3.3.1-0-offain.zip
but if I want to reboot; it says
Code:
No OS installed! Are you sure you wish to reboot?
so I went on with flashing lineageos 16
but at the end of the flash, I get
Code:

please advise

Your recovery is missed now cause when you flashed LOS was overwritten and device can't boot to system cause some step failed in the process.
If you flashed successfully mdtp images now follow the steps to boot to recovery and then follow those indicated to install LOS.

Thanks; this is what I did:
from TWRP I rebooted to recovery
it took me straight to fastboot again
so I
Code:
fastboot boot twrp-daisy-3.3.1-0-offain.img
again and mounted system partition then I flashed LOS
and the process went fine this time but when I rebooted to the system
it's back to fastboot again!

This is exactly what I tried to tell you: your issue concerning to this thread was solved.
Now you have an issue regarding how to flash and boot to system attempting to install LOS. TWRP is perfectly capable to mount/remount or unmount partitions if needed, no need an action from the user, this is not the reason why you are not booting but the method and steps is discussed more properly in the same thread.
From here you can take one of hese three routes:
- To insist with trying to flash LOS.
- Flash other rom or a previous known working rom.
- Return completely to stock by flashing a full global rom.
Just I could recommend that for the future when you flash a stock rom take a backup of the most important partitions (without userdata) this could avoid that you need to use EDL anymore.

Help with root for Alldocube M5X Pro

I am in over my head once more and could use help from someone more experienced.
The problem?
I bought an Alldocube M5X Pro tablet for my kids. First thing I did was root it using Magisk. I found the stock ROM, extracted the boot.img file, patched it with magisk manager, unlocked the bootloader and then used the fastboot command to flash the modified boot.img. Smooth sailing, worked flawlessly, kids were happy. 2 kids, 1 tablet, the happiness didn't last too long. They both wanted to use the tablet all the time. So when I found a sales promotion for the same model tablet, I decided to buy one more. Tablet #2 arrives, also an Alldocube M5X Pro, model T1006, Kernel version 3.18.60, Android version 8.0.0, same as tablet #1. I go through the same steps, but when I try to flash the modified boot.img file on the new tablet, it tells me Remote: Flash WRITE failure.
Here's what I did, step by step:
1. I verified that the 2nd tablet had the same build number as the 1st tablet. It did: T1006_V1.01_20200504
2. I enabled USB debugging in developer options and set the OEM Unlock option to ON
3. I trusted the connected computer in order to use the adb commands
4. I rebooted to the bootloader and executed the command Fastboot OEM unlock
C:\adb>fastboot oem unlock
...
(bootloader) Start unlock flow
OKAY [ 7.825s]
finished. total time: 7.826s
Click to expand...
Click to collapse
5. I executed the command Fastboot Flash boot magisk_patched.img with the img file in the path from where I'm running the command
C:\adb>fastboot flash boot magisk_patched.img
target reported max download size of 134217728 bytes
sending 'boot' (10253 KB)...
OKAY [ 0.468s]
writing 'boot'...
FAILED (remote: flash write failure)
finished. total time: 0.633s
Click to expand...
Click to collapse
6. I've tried erasing the cache and user data partitions from the stock recovery and repeating step 5, but received the same error.
And that's where I'm stuck. The tablet can reboot from there, will detect tampering and proceed to run an erase command and starts with the Android Setup tutorial.
Just for the hell of it I tried flashing the stock ROM using the SP Flash tool for Mediatek devices, which works just fine. I then tried tried flashing an older build (0304) but still received the same error when trying to flash the boot.img
I also tried flashing a custom recovery as well as booting a recovery.img but in both cases the tablet ends up booting normally, I assume because the custom recovery isn't compatible with this device.
Everything I find online about flash write failure errors seems to indicate a defective emmc however most of those are specific to the Nexus 5 phone. The difference here seems to be that I can unlock the bootloader just fine, it stays unlocked as far as I can tell and I can overwrite with a new ROM, so I'm thinking the emmc is fine.
I'm just trying to puzzle this together from what I can find online, but I could really use the help of someone with more insight into the inner workings of Android.
Any help would be greatly appreciated.

After flashing 4 different ROMs, formatting the emmc completely and doing lord knows what else, it finally dawned on me that I could simply flash the patched boot image using the SP Flash tool instead of via Fastboot. It does wipe the data, and starts the Android setup wizard, but once that is completed, I was able to install Magisk Manager and download the missing files. The device rebooted after that and came back with systemless root.
Problem solved.

DON'T store flash files on USB storage.
fastboot will timeout if your flash files are stored at a slow storage device such as a USB drive, or slow computer with eMMC drive

if you take this route, you will have an easier time get into EDL
Optional for Driver and boot into EDL: Download and extract the TOOL ALL IN ONE (credit) (untested) (can skip this step if you have driver and completed preparation step 7)
Flash Operations:
Run the MSM executable with Administrator Privilege
Boot into bootloader on 7T (if you already have adb connection, adb reboot bootloader would work as well)
Restart device: Vol Up + Power
Boot into recovery: when system reboot from step 4, immediately press and hold Vol Down + Power until recovery screen
Boot into fastboot: English -> Advanced -> fastboot
Boot into EDL on 7T
If you have OnePlus unlock token from Preparation step 7
Connect USB cable to both PC and 7T
on MSMDownloadTool, click Enum to display your device
fastboot flash cust-unlock unlock_token.bin
fastboot oem unlock
fastboot boot twrp.img
when TWRP boot: adb reboot edl
on MSMDownloadTool it will now show connected
If you don't want to wait for token (untested)
Use TOOL ALL IN ONE
Or, hold down the buttons then click start in MSM. If you release the volume buttons early it will kick you out of EDL--well at least for me. you can release the buttons once MSM starts (credit)
When MsmDownloadTool display connected, hit Start until 7T display CORRUPT message (normal behavior) and reboot into fastboot by ITSELF. If your 7T doesn't get into fastboot screen automatically, something is wrong with previous step, redo EDL flashing and do NOT proceed.
Start Power-Shell with Administrator Privilege and go to the extracted path of 10.0.13-global-oneplus7toxygen_14.o.19_ota_019_all_2009281709_1026-fastboot.zip (DO NOT USE DOS, it will fail you miserably)
Unlock bootloader: .\fastboot flashing unlock_critical (suggested, because it works, so I didn't test the oem unlock method)
To avoid potential conflict with installed fastboot binary (possibly lower version), you can either
edit the flash-all.bat, and change fastboot to .\fastboot, such that only the local fastboot binary will be invoked instead of pathed binary

Few notes
User data is wiped, again, lol
reserve partition flashing can produce error msg: FAILED (remote: '(reserve_a) No such partition'), it is OK but others should not Fail
Device will reboot once during the flashing process
After reboot, device will NOT go into fastboot screen but instead go into stock recovery screen, however fastboot will pick up and resume flashing the rest, ONLY IF YOU ARE UNDER POWER-SHELL, so DO NOT flash under DOS
if anything else fails besides the reserve partition, repeat step 7
Device will boot into system, you may use the OS updater to upgrade to the lastest firmware then relock bootloader or proceed with root with Magisk
Hope this will save you some precious time. Major kudos for previous contributions from post 1 and post 2.
All steps are recorded from memory, please let me know if any mistakes are in need of correction.
Tested working on Dec 5, 2020

I have followed this method (and literally anything else I can find) to a T and the farthest I get is when flashing the ROM, I get "Flashing is not allowed for critical partitions" - which I can only find people saying that means the bootloader needs to be unlocked, but it is?! It's definitely, fully unlocked. No matter what I try I can't get around that error during the flashing process and it stays stuck on the T-Mobile ROM.

I had the same issue with the critical partition error when I was under DOS and during the reboot process, 7T will only boot into the normal fastboot screen. In here, I always gets that error over and over. I stopped getting it when 7T boot into the recovery screen under power-shell.
Few things to make sure:
Stock cable
Power-shell in admin priv
Use local fastboot binary
If things still not looking up, I would try a different PC.
Good luck.

Yup, those are all correct and I have tried another PC. Now I'm scared I may have bricked it, because other than booting it into FastBoot it just loops on the "Your device is corrupted" screen. Any thoughts? It did this after I re-locked the bootloader to try unlocking Critical again.

Is your device is corrupt screen the one that gets displayed after the MSM EDL flashing?
If so, does your device auto boot into fastboot afterwards?
My thinking is after MSM tool, your device is corrupted, then you unlock critical flashing. Afterwards, the partitions being flashed in by the fastboot should prevent the corrupt msg being displayed. If you are all getting corrupt msg after the fastboot reboot, then something is off with the first part of your fastboot flashing.

It's that same screen, yes, but the phone is just stuck in a boot loop. It says "Your device is corrupt. It can't be trusted and will not boot." and goes black and says it again, over and over. It will not automatically boot to Fastboot, but if I mess with the volume/power keys, I can get it to the fastboot screen. But no matter what else I do it goes back to an endless loop with the corrupt message.

I think some error could have been carried over from the MSMDownloadTool flashing process. My 7T always auto boot into fastboot screen after the corrupt msg display without interaction on my end.
Try your EDL flashing part again, and at the same time, re-download the preparation step 4 file over again and try use that instead afterwards if you are still stuck on the boot loop, just to prevent possible discrepancies might be caused by corrupted file (unlikely, but it doesn't hurt right?)

Gotcha, thanks. Got it into EDL mode and am running MSM right now.

Okay, EDL/MSM was successful, then I tried flashing the ROM per the instructions again but got the same error of being unable to flash to Critical. It no longer does the "device is corrupt" error boot loop, but the phone ONLY boots to Fastboot now, no matter what I do.

Best of luck. Hope the pain stops for you soon, hah.

Can you post your power-shell display message for the last flash-all.bat invocation?

Also, are you using .\fastboot flashing unlock_critical in admin priv power-shell to unlock the bootloader after MSM flashing?

Yes, that's what I was using. Unlocking it wasn't an issue, and when I try any type of unlock command it says it's already unlocked, which I believe to be true. But it still refuses to write to critical.
I can post my powershell message when I get back home. But basically it ran fine at first, it did fail at the "reserve" portion which I read to be normal, but after that it kept saying cannot flash to critical.
I just got the phone today so I hope it's not already bricked. But the fact that I got it out of the "corrupt" loop gives me hope I can fix it. Is there any place to download the stock T-Mobile ROM so I can try and start over? Assuming it will even let me flash it. I couldn't find any by searching.

One observation I found to be very interesting.
The device should have been locked by the MSM tool through EDL flashing; yet, your device shows it's already unlocked.
I think the issue is still with your EDL flashing process as it should lock the bootloader then use flashing unlock critical to prevent critical partition flashing errors.
Also, your device is not bricked as long as you can still perform EDL flash. Just kept going and you can get it working without having to EDL flash anything else.

I see, thanks for the insight. So just so I don't mess anything up further, exactly what steps in what order do you recommend I perform?

My first instinct is to keep trying the EDL flashing until you can perform flashing critical unlock properly.
If things keep on failing, try to change your PC, driver, or other environmental variables.
It's just a painful process of elimination that you have to stick to.
Also, unless there are potential hardware issues, flashing like this shouldn't carry any more risk to brick your device compare to just using your device regularly. You aren't changing the hardware/software that is responsible for facilitating EDL.

EDL is fine, unlock_critical is fine, but flash-all gives me the same 'Flashing is not allowed for Critical Partitions' error on some partitions, and then I get stuck on the T-Mobile boot screen after. I'd think it wouldn't be the TMo screen by that point, right?
I've gone through this twice with the OEM cable and a different cable. The device was up to date with the latest TMo OTA before I started.
I'm about to try the TMo MSM to see if I can get it back to a working state.

Your 7T should be on the stock recovery screen when fastboot reboot fastboot completes. If your device boots into T-Mobile boot screen or bootloader, something is wrong with your env on PC.
You should never see T-Mobile boot screen at any given time during fastboot flashing process.
The final reboot should complete the conversion and boot into the intentional version OS.
