I have same issue. I flashed AA build. Everything works perfectly but not camera. It's not opening at all. Any thoughts on what could have gone wrong ?
[OnePlus 7 Guides, News, & Discussion] kodrnusa:
did you make factory reset?
[OnePlus 7 Guides, News, & Discussion] andromuks:
Yes .I did. I tried flashing same fastboot ROM again. But no luck. When I tried factory reset, my alert slider stopped working too. It works but I have to restart device to make it work.
[OnePlus 7 Guides, News, & Discussion] kodrnusa:
I would go with unbrick MSMTOOL and start from scratch.
[OnePlus 7 Guides, News, & Discussion] meltbanana:
I had the same issue after getting back from potato and all I did was downgrading via fastboot and then upgrading to android 10. after that my camera works again.

maybe fulldowngrade_wipe_MSM_18857_190505_1527_user.zip has the same effect, don't know cause anyway I'll stick with 10.
[OnePlus 7 Guides, News, & Discussion] andromuks:
I thought it must be happening because I'm overwriting same system parition without wiping it as a part of flashing process so i tried booting into twrp and wiping system, vendor etc, reboot to fastboot mode and then tried to flash fastboot method. didn't work.

I also tried downgrading it, didn't work.

flashed using MSM tool , din't work.

by didn't work, I mean flashing process is successful but camera and now alert slider, both not working.

Thanks bro. This fulldowngrade_wipe_MSM_18857_190505_1527_user.zip method worked. So here's what happened. Vendor partition usually has vendor specific libraries. No matter which fastboot update we flashed, It flashed same updated vendor image.

We needed to downgrade vendor which was possible with above full_downgrade package. I did see one more member having similar issue. Here's fix for this issue.(as it worked for me).

1. Use MSM tool and started from scratch with Hydrogen OS. Set it up.

2. Download "fulldowngrade_wipe_MSM_18857_190505_1527_user.zip" package. Renamed it to "update.zip" .

3. To locally update it, go to settings, system -> system updates. click settings at top right and select local update.

4. locate "update.zip". It will start updating your phone.

5. Reboot after finishing update. Setup device again .

Done ! Works for me.
[OnePlus 7 Guides, News, & Discussion] kamikaze702k:
Is your alert slider working now also? I'm in the same boat
[OnePlus 7 Guides, News, & Discussion] andromuks:
Yes. Everything works perfectly fine. :D

this msm tool?

https://xdaforums.com/oneplus-7/how-to/unbrick-tool-oneplus-7-msmtool-hydrogen-t3953240
[OnePlus 7 Guides, News, & Discussion] andromuks:
Yes. Be careful while using it as it flashes your phone completely including every partition. make sure that your phone doesn't get disconnected during flashing.

1. Flash with above MSM tool

2. Setup your device

3. Download Full_downgrade package : https://forums.oneplus.com/threads/oxygenos-9-5-6-for-the-oneplus-7.1064426/page-35

4. Rename it to "update.zip"

5. Local upgrade with above "update.zip" from settings->system updates -> settings ( top right corner) -> local upgrade .

6. Reboot and setup device again.

Thanks :)

how exactly do i flash the msmtool zip with hydrogen?

file is "OnePlus7_guacamoleb_14_H.10_190523_MSMTOOL" but i cant open it, and not sure how i need to flash this, which method?

i have also saved the "fulldowngrade_wipe_MSM_18857_190505_1527_user.zip" and renamed it to "update"

hi guys i have a proble mi have op7 not pro but when i use these method i have problem qualcom crash dump dm-verity device corrupted force dump kernel restart how to fix that :c
[OnePlus 7 Guides, News, & Discussion] kamikaze702k:
Are you installing the rom from op? Fastboot rom? If yes then don't flash or attempt to install the dm verify zip, I'm assuming that's what your doing?

If u are mentioning qualcom then that's completely different like what I had to do to restore to stock, follow the above posters instructions.

Can you please post exactly your current situation and what your attempting to do so I can guide you further

---------- Post added at 08:42 PM ---------- Previous post was at 08:32 PM ----------

This thread is good but indirectly it's interconnected with other threads too, certain users like me who tried posp, tried to revert back using fastboot was successful but no camera or alert slider was working, so I had to get the msmtool hydrogen zip flash that then update locally to restore but I would not have known that if it wasn't for the posters here, it can get a bit confusing and frustrating too, at the same time not wanting to spam threads too but those issues are linked together and without information and help from others we would be stuck.

I have now personally recovered the device to full stock and will be leaving it alone there, no root no unlocked bootloader, we don't have many options for this device anyway and the stock rom is pretty good as it is.
[OnePlus 7 Guides, News, & Discussion] Nemeroz:

its version is 10.0.2.GM57

which file is the right one to flash through fastboot to re-install stock rom? please, give me a direction
[OnePlus 7 Guides, News, & Discussion] SinNombre8:
QUALCOMM CrashDump Mode

Thanks for this tool!

I've followed some guided steps (not from this thread) which failed to work, by trying to fix it, I think I made it worse...

My phone is now stuck on:

QUALCOMM CrashDump Mode

dm-verity device corrupted Force Dump kernel_restart

I've downloaded the MSM Download tool, ran it, but I can't seem to identify the phone on the tool.

I do see it on the device manager as "Qualcomm HS-USB Diagnostics 900E (COM3)" under "Ports (COM & LPT)"

Any idea why?

* Phone is fully stuck on this state, I can't reboot / power off no matter what I try

* The file name I've downloaded is "ANDROID+10+OOS+10.0.2+GM57AA+guacamoleb_14_O.22_191107_repack.zip"

* Tried pressing "enum" (in case wondering)
[OnePlus 7 Guides, News, & Discussion] mikefnz:
Press power & volume up/down until you get into fastboot.
[OnePlus 7 Guides, News, & Discussion] SinNombre8:
Thanks for the reply, but this doesn't work.

The only way I get to see any screen output from the phone is when I let it drain out of battery, connect to the PC and let it tell me 'no sufficient power'

After some further research I'm quite sure I've ran over both partitions, making this a hard brick...

I've tried asking OP support if this is salvageable, pending reply.

AFAIU this is not recoverable without any JTAG or some other debug interface.

I need help I figured it out so that the phone enters the fast mode then. How can I revive my Oneplus 7? can somehow install Oxygen stock from fast mode?
[OnePlus 7 Guides, News, & Discussion] strongst:
You posted it twice, so this is the right thread as you can see from the first post and topic headline. Your question is answered :)
[OnePlus 7 Guides, News, & Discussion] kixx22:
I had the same problem. What helped me:

- install TWRP (via fastboot mode)

- enter TWRP and then to adb sideload

- the phone connected to the computer should now appear in my computer

- Download the latest soft from Oneplus to your computer and then copyit to your Oneplus normally

- later install soft via TWRP

- reboot and everything should be ok

Hello!

Need some help, I hit something.

I have an oneplus 7 smooth device.

I wanted to close the bootloader because of a phone sale.

But I didn't do something well.

I did it with the all in one tool program, but once I did it it worked.

I pressed the lock button and the phone restarted, but something was wrong

He writes that "your devices are corrupt. It can't be trusted and will not boot"

In addition to the bootloader I can start and choose the usual options, but recovery. it comes in.

The all in one program sees the phone in fastboot but does nothing.

I can't switch EDL at all, so MSMdownloadtool won't work either.

Hope not trash poor!

Someone can help, thank you!

sorry bad english,

Tibi

[OnePlus 7 Guides, News, & Discussion] RainGater:
If you ever need to go back to completely stock, would this work instead of a fastboot ROM?

1. In TWRP, format data, where you have to type YES

2. Transfer the stock ROM from OnePlus 7 website: https://www.oneplus.com/global/support/softwareupgrade/details?code=PM1574156235282

3. In TWRP, flash the downloaded stock ROM.

4. Reboot

5. Once the system is up, go to bootloader and lock the bootloader:

adb reboot bootloader

fastboot oem lock

Anyone tried the above steps to see whether it works for you? I am compiling the instructions for a friend who wants to go back to stock. I know you can flash the fastboot ROM as mentioned in the OP but I see posts where people complain that camera + alert slider is not working after you go with the fastboot ROM approach.
[OnePlus 7 Guides, News, & Discussion] strongst:
Why you ask this in the fastboot roms thread?

It depends on which rom you are and which rom you want. A factory reset will do the same along with locking the bootloader.
[OnePlus 7 Guides, News, & Discussion] RainGater:
If I shouldn't post my question here, that's fine. I take it back.

My friend is on POSP ROM and that's why I listed the steps to go back to stock. Would the steps that I outlined work flashing a stock ROM from OnePlus website?
[OnePlus 7 Guides, News, & Discussion] strongst:
I was just wondering cause it's necessary to know what rom he has actually, so a factory reset cannot help here.

He can also use unbrick tools, or flash stock rom like described before from you.

Can this zip be flashed using just twr

---------- Post added at 09:46 PM ---------- Previous post was at 09:43 PM ----------

Can this zip be flashed using TWRP recovery alone?
[OnePlus 7 Guides, News, & Discussion] sekk:
absolutely NO.

download the zip to computer, unzip it, and just start the flash-all.bat file after you plugged your device to computer AND after check if adb is working

Question

For X reason . I want to relock the bootloader

should i flash it on both slot A/B >>> directly via fastoot relock the bootloader

Or

I need first to boot to the system >>>fastboot >>> relock the bootloader
[OnePlus 7 Guides, News, & Discussion] sekk:
all you need to do is just reboot phone into fastboot mode, connect usb, check if fastboot command is working, if so, just run the flash-all.bat and done
[OnePlus 7 Guides, News, & Discussion] M.Kader:
If you did so .you only flash oos on one slot . That is not enough . You need to flash at both slots .

But if reboot your device it will Detected the unlock bootloader and it will remove some apps like live wallpapers .... But that is not problem

I just want to make sure it will be NP after that
[OnePlus 7 Guides, News, & Discussion] sekk:
no man, it won't. I have just done like I said, everything working after reboot.

before msm, using slot A

after using msm, it seems I'm still using slot A
[OnePlus 7 Guides, News, & Discussion] M.Kader:
I already did it .

Flash 10.0.4 on both slots and stock recovery . Boot system .

Using msm tool >bootloader locked>update to 10.0.5 using ota. :silly:

Qualcomm Crashdump Mode after using flash-all-partitions.bat

My phone was almost bricked trying to move back to stock from custom rom so I decided I should use the flash-all-partions.bat after using it upon reboot I enter Qualcomm Crashdump mode. So I tried to wipe data and cache through OOS recovery but even after that it doesn't boot into OPS instead goes to Qualcomm Crashdump. Is there any work around to not encounter this issue maybe manual flash would fix it?

@mauronofrio I have a OnePlus 7 I'm trying to return to stock, but when I flash the images here, I end up in the Qualcomm crashdump now.

I think it's because I didn't uninstall Magisk. I had a stock rom on it, but with Magisk. so I just locked it assuming the wipe would take care of everything.

I just remembered I also had TWRP installed.​
[OnePlus 7 Guides, News, & Discussion] MrMuscle:
I had OOS 11 with TWRP (outdated version because phone updated itself without my permission), Magisk, Root. unlocked bootloader.

I wanted to go back to stock and I used flash-all.bat from 10.0.5-EUROPE-OnePlus7Oxygen_14.E.25_OTA_025_all_2003270109_b4bd604af0a00-FASTBOOT

The flashing was done few minutes ago and it was succesfull. Phone has now booted to language selection screen which is the first screen you see when you buy a phone and turn it on. Before going any further; Is now the right time to boot to fastboot and lock the bootloader, like shown in this video:
[OnePlus 7 Guides, News, & Discussion] MrMuscle:
As a reply to myself. I tried to power off the phone and ended up with:
