[Weird..will adb read it? It may be in "recovery" now..just try adb devices, adb reboot bootloader..sounds nuts..but try it[/QUOTE]

Tried all of that and still nothing computer doesn't see the phone. I'm about to head over to tmobile and get me another. Sucks I have to wait another seven days for a token
[OnePlus 6T  Questions & Answers] LLStarks:
Won't you need a new SIM unlock too?
[OnePlus 6T  Questions & Answers] hartleyshc:
Yeah that's what I downloaded, but it's not broke down. Most of the data is in a payload.bin file.
[OnePlus 6T  Questions & Answers] bp328i:
I hate to be the one to say this but this is one of the reasons carriers started looking bootloader. People bricking their phones and returning them.
[OnePlus 6T  Questions & Answers] mackentosh:
This true but oh well
[OnePlus 6T  Questions & Answers] Dark Nightmare:
You have to hold the power button for a good minute, maybe even try holding the fastboot combo for a while and see what happens...
[OnePlus 6T  Questions & Answers] bp328i:
If it happens enough with the OnePlus 6T I wouldn't be surprised to see TMobile stop allowing the bootloader to be unlocked.
[OnePlus 6T  Questions & Answers] Dark Nightmare:
It says build version and hardware version don’t match, so modded build.prop should resolve this? Unless it’s actually checking the modem sig, though that shouldn’t have flashed if it wasn’t a match.
[OnePlus 6T  Questions & Answers] mackentosh:
I've tried that to, it's weird cause it makes a connection noise when I connect it to my computer and a disconnect noise when I unplug it. But the screen stays black.

Is this what you used?
[OnePlus 6T  Questions & Answers] mackentosh:
Yes that's exactly where I got it from 9.0.4
[OnePlus 6T  Questions & Answers] LLStarks:
That might the emergency download mode (EDL mode) kicking in. There are drivers for this mode and rescue might be possible, but I'm not familiar with the procedure in the slightest. I don't think the tools for the OP6 have been updated to or work with the OP6T.
[OnePlus 6T  Questions & Answers] :
U can prob flash just the system.img from 9.05 and would he fine,, cuz treble...
[OnePlus 6T  Questions & Answers] Dark Nightmare:
I believe the screen generally stays black in fastboot, check fastboot devices via cmd when the phone is connected to see if it shows up or device managers, if it does, proceed to attempt flashing, or twrp.
[OnePlus 6T  Questions & Answers] hartleyshc:
Well he did the complete flash. It flashes all partitions, then boots into TWRP and flashes persistent and critical partitions as well.

I'm mostly curious if any of those partitions failed to flash at any point.
[OnePlus 6T  Questions & Answers] Addiso:
Want to at least flash 9.0.4 myself, but this is my daily. Don't know if I can risk it knowing you bricked but on 9.0.5.
[OnePlus 6T  Questions & Answers] rootmaster96:
I think a full fastboot install of 9.0.5 would work fine seeing as OP used only OTA via local upgrade, something that was said to brick the device if it was modified (BL unlocked, root, etc.)
[OnePlus 6T  Questions & Answers] jerrywmilton:
Just like every other OP phone...there will soon be an "Unbricking MSM Download Tool" that directly flashes via the Qualcomm. Basically there is no way to truely brick an OP Qualcomm phone.
[OnePlus 6T  Questions & Answers] Addiso:
Gna go ahead and try this. Don't want to jump into 9.0.5 just yet because of your brick.
[OnePlus 6T  Questions & Answers] hartleyshc:
Yeah we have the links to it. It's just password locked at the moment. But we will get it in time. Either password will be brute forced, or the password will be leaked.
[OnePlus 6T  Questions & Answers] Velrix:
I just did a full install of 9.0.5 and it worked just fine. I would suggest that. I do not have any TWRP or anything on the system right now.

It boots however once you get to the UI it reboots shortly after. (Roughly 5 seconds) and a full wipe/reset does nothing to stop the reboots after booting to the OS.
[OnePlus 6T  Questions & Answers] hartleyshc:
What was your process? Did you use the 9.0.4 fastboot version then used a full (not incremental) OTA from recovery?

Did you use just the 9.0.5 fastboot version? Or use both fastboot versions? Also which bat file did you use when flashing?
[OnePlus 6T  Questions & Answers] seniorstew:
So.. It didn't work just fine then
[OnePlus 6T  Questions & Answers] Velrix:
I edited the post I should have marked out the previous comment and I will....
[OnePlus 6T  Questions & Answers] LLStarks:
I'll take reboots as an encouraging data point any day over a hard brick.

At least we've proven that OTAs or incomplete flashes are at fault.
[OnePlus 6T  Questions & Answers] jdidtht:
Lol

---------- Post added at 01:56 PM ---------- Previous post was at 01:52 PM ----------

Hey, at least we have access finally, and are able to flash anything at all. There's been so many "nope you won't be able to do that" and then a day later someone does it, so it's encouraging.
[OnePlus 6T  Questions & Answers] LLStarks:
But now we need research and ground rules to protect more casualties. Key tools that OP6 users enjoy simply aren't available yet, even for global 6T models.
[OnePlus 6T  Questions & Answers] hartleyshc:
Still curious as to what flash.bat was used. There's a few of them that flash different partitions in fastboot (and optionally a few critical partitions in TWRP).

The original poster got his to boot when he flashed ALL partitions. That means it temporarily booted to TWRP to flash partitions that aren't accessible through fastboot.

And I'm even more curious to if all of these partitions successfully flashed. It's very possible for the script to fall flashing a partition yet keep flashing the rest.
[OnePlus 6T  Questions & Answers] Velrix:
Ok so I fixed the issue. At first I used the flash-all.bat (default one) not the flash-all-partitions.bat (inside others_flashall zip).

Once using the "flash-all-partitions.bat" it fixed the rebooting issue. Ill get some pics shortly!

I am glad to report everything is working 100%... O YA!

Just so everyone knows. The IMEI on the second sim slot is the same as slot 1, so I do not think it will actually work.
[OnePlus 6T  Questions & Answers] justibasa:
Just don't take the next ota that comes out. ??
[OnePlus 6T  Questions & Answers] Addiso:
Can confirm this as well. Jumped the gun and phone is on 9.0.5 Unlocked OOS. I see two imei as well but are the same. The new gestures are more fluid. ??

Flashing all the partitions bat does the trick. Was a bit scared because the phone did take awhile but you do just let it sit for awhile and it's good.
[OnePlus 6T  Questions & Answers] hartleyshc:
Even with one imei it is possible that we could still use two SIMs, you would just only be able to use one at a time. Could still be useful, there's dual SIM phones out there with one imei and this is how they work.

And it *might* be possible to change the second imei, but that is a discussion that is NOT allowed at all on xda and is illegal in pretty much most places, even using another device that you own as a donor imei. Just putting that out there before the discussion goes that way. Just assume it is not possible.

Also I should be getting my unlock bin either Sunday or Monday, at that point I will be working on creating a backup script that can backup all of our partitions so it will be possible to flash back to T-Mobile via fastboot if needed.
[OnePlus 6T  Questions & Answers] justibasa:
Any chance someone can do a complete step by step tutorial in the general section. I need something pretty detailed. Its not that I haven't done this before I just want to be extremely careful. Want to read through it 1 or 50 times before I actually flash it. I'll get my token tomorrow. Just want to make sure I get it down. Its the type of person I am. I like to read everything several times before I attempt.
[OnePlus 6T  Questions & Answers] Pain-N-Panic:
The OP stated he located a "flash all partitions.bat" file which seemed to do the trick on the 9.0.4 build to get him up and running. Does OP release the full OOS images on their site like Google does for the pixels? It should come with the same batch file

---------- Post added at 09:16 PM ---------- Previous post was at 09:14 PM ----------

Where did you get the 9.0.5 images from?
[OnePlus 6T  Questions & Answers] ska8tdude:
I, too, just installed the 9.0.5 on my T-Mobile version and everything is working fine so far. Can also confirm the IMEI numbers are the same. I can definitely tell the difference in the fingerprint speed as well, it's quite a bit better.

Search a bit there is a thread about it. And OP always release full ROM zips, .img files are inside.

After this flashing process does this remove the full screen magenta bowel movement that T-Mobile took on the boot screen ?
[OnePlus 6T  Questions & Answers] justibasa:
That works for me I have to work too 8:30 tonight, and probably won't get the unlock code till tomorrow so no worries.
[OnePlus 6T  Questions & Answers] Addiso:
Yes it does, looks just like a unlocked 6t without the 2nd imei.
[OnePlus 6T  Questions & Answers] dadoc04:
?? magenta bowel movement
[OnePlus 6T  Questions & Answers] LLStarks:
It should now be possible to do apples to apples comparisons of the modems when rooted and using Network Signal Guru.

Doesn't the flash-all-partitions call for a TWRP.img? What are you using for that?
[OnePlus 6T  Questions & Answers] ska8tdude:
All of the flashing is done via Fastboot, it doesn't require TWRP. In the original download, I copied over all of the BAT files from the "Other_flashall" folder and all of the files in the "Images.zip" archive to the root folder. I then just ran the "flash-all-partitions.bat" file. Took 2-3 minutes or so to flash everything, then I had to reboot the phone.
[OnePlus 6T  Questions & Answers] hartleyshc:
Not anymore.

The official images from OP contain a project.bin file with all of the information because of treble. There's no longer a full factory image through recovery like before.

These images that are used are created by users to be flashed through fastboot.
[OnePlus 6T  Questions & Answers] Dameon87:
Would one of you who were able to get the OOS 9.0.4 or 9.0.5 flashed be able to take a screenshot of your modem version please? I'm curious if the actual modem flashed.

Edit: Nevermind. It does look like the modem was flashed. So the nonsense about the signed modem appears to have been false.
[OnePlus 6T  Questions & Answers] hartleyshc:
Then critical partitions aren't being flashed. Look at the thread where you got the files. The flash-all-partitions is supposed to boot to TWRP to flash additional partitions that cannot be flashed through fastboot.

You might need to replace the TWRP.img file in the image with the one for the 6t.
[OnePlus 6T  Questions & Answers] dhoang:
Do you notice any problems with the LTE signal, connection, or speed?
[OnePlus 6T  Questions & Answers] LLStarks:
How is this working without the criticals? How critical are they and would that be the difference between brick and boot?
[OnePlus 6T  Questions & Answers] Haz3:
If these devices are anything like the pixel devices your critical partitions contain your boot images and aboot and all that. Fastboot flash unlock_critical would unlock it to allow flashing.
[OnePlus 6T  Questions & Answers] ska8tdude:
Interesting, I do see that the "flash-all-partitions-recovery-criticals.bat" file does call for the TWRP.img file. It did not receive any errors, so I'm not sure how it completed without it being present.

I'm not the best to ask about that, the LTE speeds near my home are always slow. I did a test though and I got the same speeds I did when using the T-Mobile ROM.
[OnePlus 6T  Questions & Answers] mackentosh:
Yes
[OnePlus 6T  Questions & Answers] LLStarks:
I'm guessing that abl.img is the bootloader.

And just to clarify, the P2XL and N6P use fastboot flashing unlock_critical.
[OnePlus 6T  Questions & Answers] hartleyshc:
It's just one part of it.

Also the pause command at the end of each script is supposed to wait for a key press to continue for the rest of the script. If the recovery-critcals.bat failed on all of those commands (which I'm sure it did since TWRP didn't boot) then it wouldn't show the errors but for a second and then it would have been just gone. You'd need to scroll through and see what didn't flash.

Every command that uses adb didn't flash. TWRP is needed for that.

TWRP.img will need to be in the same directory as the bat file.

These are simple bat files. They're not going to stop on an error, they just keep going to the next command.
[OnePlus 6T  Questions & Answers] Velrix:
Yup it's all gone :)
[OnePlus 6T  Questions & Answers] Haz3:
Yeah it's flashING, my phone autocorrected me lol and if my memory serves me right I think it was abl. But I'm not 100% sure tho
[OnePlus 6T  Questions & Answers] seniorstew:
On my pixel 2 xl you had to fastboot unlock the critical partion as well as the regular unlock.

fastboot flashing unlock_critical
[OnePlus 6T  Questions & Answers] cwalker0906:
That was only at first, after a couple of updates it wasn't needed anymore, it mentions it on Google's factory image page
[OnePlus 6T  Questions & Answers] nima0003:

[OnePlus 6T  Questions & Answers] Zachisimo:
So you are unlocked? How did you receive your unlock already?
[OnePlus 6T  Questions & Answers] hartleyshc:
His new one isn't unlocked.

But if you mean in general, people are getting their phones bootloader unlocked now. After SIM unlock you have to wait 7 days to get the unlock file from OnePlus.
[OnePlus 6T  Questions & Answers] LLStarks:
Somebody needs to take a chance on criticals before we write a guide. Not having the correct bootloader in place could end up being an unnecessary risk and long-term concern with future OTAs.
[OnePlus 6T  Questions & Answers] :
I intend on unlocking critical anyway. Always do.
[OnePlus 6T  Questions & Answers] mackentosh:
I'm sim unlocked already I just gotta resubmit for a token now which will be another 7 days unfortunately
[OnePlus 6T  Questions & Answers] Addiso:
True, but I know we can pull the partitions and compare with the unlock version first before flashing any type of critical, just for the safety that maybe there is something with a different signatures that may throw a brick as critical involves more partitions. Correct me if I'm wrong just assumptions based on other devices I've owned . This is my first oneplus device.
[OnePlus 6T  Questions & Answers] LLStarks:
Do we even need to unlock them? Is it offered as a fastboot option?

Maybe it's just as simple as running the critical bat with the right twrp and critical imgs in the same folder.
[OnePlus 6T  Questions & Answers] Dark Nightmare:
Shouldn't we do a system dump before tinkering?
[OnePlus 6T  Questions & Answers] hartleyshc:
Yes.

All partitions should be dumped before replacing. If I was unlocked I could write a simple script to make a dump.

We've already had one hard brick. Unless you're prepared to return your device and get a new one, I wouldn't advise attempting to flash the critical partitions.
[OnePlus 6T  Questions & Answers] Dark Nightmare:
I unfortunately did the dumb thing and went ahead and flashed to 9.0.5, but I can dump my current working partitions?
[OnePlus 6T  Questions & Answers] djkinetic:
Not necessarily dumb but perhaps careless.. especially if u had flashed only the ota and not the full rom.
[OnePlus 6T  Questions & Answers] Clownfish44:
It would be great if someone could make a thread as a guide on how to make a complete backup and install the real version for now and then edit it as we get more info and test more. If there was a guide on what worked as of now we could test all of the other options but a starting point would be great.
[OnePlus 6T  Questions & Answers] :
FYI adb backups work. Before unlocking the bootloader...adb backup -all
[OnePlus 6T  Questions & Answers] Dark Nightmare:
Full rom, I've been following this thread all day prior to flashing, knew better than to attempt flashing the OTA, I'm okay with being on 9.0.5 until we have definite info on using OTA updates or if we're restricted to full rom flashes, which I absolutely do not mind in the least, current flash is tons better than stock 9.0 tmobile build, loving the gestures so far.

---------- Post added at 08:39 PM ---------- Previous post was at 08:37 PM ----------

I skimmed over the backup, but the flashing process seems definite.

Boot into fastboot after unlocking your bootloader and flash using flash_all_partitions.bat and not flash_all.bat.

---------- Post added at 08:42 PM ---------- Previous post was at 08:39 PM ----------

can someone with an unlocked bootloader do this please? We need a stock dump of the tmobile system until we have a base rom to work with.
[OnePlus 6T  Questions & Answers] :
Unlocked. Not locked.
[OnePlus 6T  Questions & Answers] hartleyshc:
adb backup does NOT back up everything we need. It makes a backup of your data. It is NOT making backups of the partitions you're replacing.

You need to be BL unlocked, use TWRP to use adb shell and use the dd command to create an img file of EVERY partition by backing up the mounting points. It's not as simple as adb backup -all.
[OnePlus 6T  Questions & Answers] Dark Nightmare:
figured
[OnePlus 6T  Questions & Answers] Clownfish44:
Do I need to reset before dump? I do not want to leak my data...
[OnePlus 6T  Questions & Answers] Dark Nightmare:
Just don't share your data partition.
[OnePlus 6T  Questions & Answers] hartleyshc:
No. But you need to back up the correct way. Your data is stored in ...... You guessed it, the data partition.
[OnePlus 6T  Questions & Answers] Clownfish44:
What is the commands I must run and where would you like it uploaded and when I get my unlock bin tomorrow I will do it.
[OnePlus 6T  Questions & Answers] Dark Nightmare:
So what have we gathered so far?

Flash full rom only flash using flash_all_partitions.bat

Do Not attempt to update using the OTA files.

Stock system dump: pending

Did I miss anything? Is anyone willing to do full rom flashes from 9.0.4 to 9.0.5? Or has anyone done that successfully? I believe the first brick was OTA.

Partitions here: https://xdaforums.com/showpost.php?p=78089595&postcount=4
[OnePlus 6T  Questions & Answers] hartleyshc:
Look at my previous post. You need to use TWRP to adb shell and DD the mounting point of every partition. There's also hidden partitions.

There's a dump thread that's been locked here. You can look at that for the partitions. But you'll need to use cat /proc/partitions But that dump is of the global rom. It's unknown if the partitions match the T-Mobile version.

You need to be proficient in Linux. There's no just blanket command to back up everything. You need to look for current partitions. Search to see if any are hidden. Use dd to back them up to img files.
[OnePlus 6T  Questions & Answers] Nileshdd:
Were you charged restocking fee when you returned the old one to TMO?

Maybe we can write a linux script that he can test? i'd do it tomorrow, but I already flashed over it.

Though I have an idea I'll test tomorrow, I'll change my active partition and see if my original stock rom is still there, if it is, I'll make the backup in the morning.
[OnePlus 6T  Questions & Answers] Addiso:
Full rom flashes from 9.0.4 to 9.0.5 work as long as we're using the flash all partitions bat file

Sadly I wish I can pull the aboot from our stock tombile rom but I don't even have a tmobile 9.0 file to go back to.

Edit, thanks for letting me know.
[OnePlus 6T  Questions & Answers] jerrywmilton:
I have both the OP version (for me) and the Tmobile locked (for my daughter)...prior to the Tmobile variant this go around... one could just chat with OnePlus and they would use the MSM tool to flash the Qualcomm on all previous models. I'm guess once the MSM recovery tool is out for the OP6T, the "easiest" way to go from Tmobile to Global will be via that tool. Heck I used it a few days ago to take my OPO from unlocked TWRP/Lineage OS back to factory locked CyanogenMOD in like 2 minutes flat for the trade-in.
[OnePlus 6T  Questions & Answers] darkfangex5:
I can't even tell since XDA won't let me open the image but, is it the same imei for both 1 and 2 or are they different?
