Hey guys my OP 8T got stuck on Qualcomm Crash Dump Mode and I tried this method and got successful download. But main issue is my OP 8T again boots on in Qualcomm CrashDump Mode. Any suggestion guys...
[OnePlus 8T Guides, News, & Discussion] Nixsuki:
Great Day!

Hello, need help although I installed the QCOM from the above mentioned. After flashing I get this message at COM 3 "Automatic detection of DDR failed" I wonder what are the lacking since I updated my drivers. Please Help.

Device: KB05AA (Globalized Chinese OnePlus 8T)

Thanks in advance.
[OnePlus 8T Guides, News, & Discussion] OTAx1:
What operating system are you using?

Make sure to reboot phone & PC 1st after installing drivers. If you still get error message there's a couple other things to simplify process. I got that same error initially but later got it working.

In any case you need to use admin (root) permissions from terminal.

This error seems to appear on older slower 32 bit Windows PCs more than others.
[OnePlus 8T Guides, News, & Discussion] Nixsuki:
I used Acer Aspire 64 Bit with Windows 8.1 all works including adb/fastboot and updated qcom drivers. I also grant administration to the msmtool flashing on its way but the error appears. I tried also switching ports noting happens.

I flash stock Oxygen International to KB2000 Chinese flashed. It is possible?
[OnePlus 8T Guides, News, & Discussion] OTAx1:
As long as your 8T is listed in Windows Device Manager as anything without an error message it should be good to go. Make sure to use only the unbricking version of MSM Tools for your hardware model.

After unbricking, go through default setup, accept all updates, connect to any network, enable developer mode then switch on unlock oem bootloader. You have to unlock bootloader to flash anything, after that should be good to go.
[OnePlus 8T Guides, News, & Discussion] Nixsuki:
Actually bro it's not a brick, just want to reflash the stock Oxygen flashed with my KB2000 OnePlus 8T or any method to reflash the stock oxygen to my chinese device. Oh so this method are just to unlocked and brick device? Sorry I'm new again to OnePlus device since my last device is OP3.

Please enlighten me. Thanks
[OnePlus 8T Guides, News, & Discussion] OTAx1:
You should be able to do that after unlocking. If the device gets bricked then use MSM Tools to restore to original configuration, not international.

Look in this thread:

[OnePlus 8T Guides, News, & Discussion] OTAx1:
In Fastboot go to Recovery mode & then ADB mode, should be able to use MSM Tools then :)
[OnePlus 8T Guides, News, & Discussion] :
Thank you for your answer. I've tried to installed pixel experience since my phone is not working, but, I couldn't. And to install PE, I installed custom recovery mode for PE. Do you know how can I go to the ADB mode in recovery mode?

Thank you.

EDIT: I've done it. I used Oneplus cable and reinstalled qualcomm drivers.

(Google Translate)

Hello guys, after 3 hours of research and at least 15 to 20 complete reboots, I finally made it with this QDLoader HS-USB Driver_64bit_Setup I think. I have root with magisk of course and I tried to update version 11.0.7.10 through magisk so as not to lose root. After I chose from magisk to do the restart OTA, it never opened, it always closed and opened in recovery. I decided to use the unbrick method but my mobile was never connected. So I tried to install these Drivers, rebooted the pc and power off the phone. After opening the pc and opening the program it did not even show me a COM input, so I open the mobile with the three keys and I waited for a while until the mobile started to boot so I was bored to do force stop and I let it open and voila.

If anyone knows a solution for sure let them write below so that someone else knows what to do. (Hopefully when I do a simple reboot or when my phone shuts down from battery I hope I have no problem opening it.)

Postscript: When I entered the Qualcom method, with the three keys, that is, the mobile phone turned on after 10 seconds and I did not have time to pass the drivers manually. Also for the first time I only turned off the cashe which did not work. Of the many reboots, only at 4 did I force stop. I know you sound crazy that he did it with the drivers, I do not know how he did it but I know that it happened after my attempt to update. Finally the update succeeded.

Great! I able to roll back from Latest Hydrogen to Stock Oxygen KB05AA using this link and files:

This webserver contains various resources that may be useful to the OnePlus community.

Also I used the latest OnePlus USB Drivers so no worries by flashing Custom ROMs now! Thank you 😇

Hello,

I'm using the MSM Tool with OxygenOS 11.0.5.6 and that's only works,

Why OxygenOS 11.0.0.0 is not working?

Device: KB05AA

Model: KB2000

- Help
[OnePlus 8T Guides, News, & Discussion] Some_Random_Username:
Added OOS 11.0.7.9 (Global and India) and 11.0.7.10 (EU) MSMs.

No idea, sorry
[OnePlus 8T Guides, News, & Discussion] Dior DNA:
then, maybe, use what works and, also, is more recent?
[OnePlus 8T Guides, News, & Discussion] Nixsuki:
Thanks Sir, Since no need to roll back since then.

Most recent is highly recommended.
[OnePlus 8T Guides, News, & Discussion] Nixsuki:
Yeah most recent works as always 😉

[OnePlus 8T Guides, News, & Discussion] dominicstg2:
so i can restore back to oss but there is this odd issue it says ready to complete, then redoes the install again any ideas why?
[OnePlus 8T Guides, News, & Discussion] pikatenor:
Today I received a new OnePlus 8T (KB2000, Chinese version) and tried to switch from HydrogenOS to OxygenOS.

Since the phone had the latest H2OS preinstalled, I tried to do the switch in this method instead of applying the OxygenOS installer zip.

Unfortunately, MSM Tool launched and flashed fine, but then when I tried to boot system or recovery, the screen only shows "Qualcomm CrashDump Mode" and I could only boot into fastboot mode.

(Since the bootloader was locked, there is almost nothing I could do in fastboot.)

I've tried different versions flashing, or getting the H2OS version of MSM Tool from Chinese OnePlus forum and switching back to the H2OS, but I ran into the same crashdump result.

Has anybody else encountered the same problem with the latest hardware?

Could you provide a newer version of MSM Tools?
[OnePlus 8T Guides, News, & Discussion] pikatenor:
I found several posts on Chinese OnePlus forum that MSM Tool a.k.a. 9008 causes CrashDump on devices with 7.0.12 pre-installed that were produced after 3/9.

Apparently the author managed to get a new version of MSM Tool from customer support, but the distribution link is hidden, I couldn't see it as I don't have a phone number in mainland China and can't create an account. sigh...
[OnePlus 8T Guides, News, & Discussion] pikatenor:
Finally, I just got the MSM Tool mentioned in that post and was able to get my phone back to H2OS!

Here is the link for those who don't have a OnePlus account or Baidu account:

4.62 GB file on MEGA

mega.nz

(Note that this is for H2OS 11.0.7.12.KB05, not OxygenOS.)

Hope this helps someone out there.

I have also noticed few tips when using MSM Tools:

- If you get a "packed image not exist" error, make sure that your downloaded path does not contain multi-byte characters

- If downloading image to the phone fails in progress, you can try again by checking the "Use Firehose Lite" option (to use little slower and safer protocol)

my oneplus 8t wont go into msn mode :( it just goes into fastboot mode
[OnePlus 8T Guides, News, & Discussion] sbcrumb:
I had a heck of a time getting mine into msn mode, one thing I noticed was in Windows Device manager it had a qualcom usb driver with a yellow triangle, so I had to install the driver for it manually then start over again and I was finally able to get it to restore. Maybe check if the driver is not installed properly.

After an unsuccessful root, a friend of mine brought me his phone, KB2003 version. The phone enters recovery, fastboot, but it's stuck in a bootloop with the animated logo keeps spinning.

Tried to follow the instructions from the first post, but I got stuck in param preload failed.

What am I doing wrong?

LE: Problem solved on another laptop, older than mine, but with the same OS, windows 10 pro.

Hi,

my OP 8T is not brick, but I installed Lineage OS and now I would like to come back to Oxygen OS. I don't know which are the steps to follow. For sure there is no TWRP to use. My phone is rooted, I used Lineage recovey for installing lineage OS.

Hey,

i had a bit of a struggle to get into edl/download mode and this method worked

also for my 8t, just in case someone faces the same issue!

When I try to use "update driver" and use the file that OP posted, windows says it cannot find a driver. It won't recognize my OP8T.
[OnePlus 8T Guides, News, & Discussion] TheMystic:
1. Download OOS from OnePlus website, for your device model.

2. Reboot to recovery.

3. Take a Nandroid backup.

4. Wipe System, Data and Cache partitions (don’t wipe internal storage).

5. Flash/ Install OOS.

6. Reboot. OOS may replace Lineage recovery with Oxygen recovery.

As long as your phone shows signs of life, it can be resurrected.

unfortunately i don't know how. i followed the steps, i got the params preload failed message. tried installing qualcomm drivers and msm doesn't show a single device now. if anyone can help me fix my phone, i will pay 100€ via paypal

update: MSM shows the device again, but I get the param preload failed message. driver is installed.

The great thing about this community is people are here to help each other out with the intent to help, and not make money. But you can consider making that payment to some reputed child welfare organisation in your region. :)

I haven't gone the rooting way yet on my device, so unable to give you step by step guidance. But I'm sure someone else will be able to help you out.

I can understand your frustration, but the good part is your phone is still alive. It is only a matter of time to get it up and running. All the Best!
[OnePlus 8T Guides, News, & Discussion] confusednoob5:
I was able to remove the driver I installed through windows safe mode. The driver from OP doesn't work for me ("windows could not find drivers for your device." error message from device manager).

This is what I see in Device Manager:
[OnePlus 8T Guides, News, & Discussion] BillGoss:
You need to extract the .cab file containing the Qualcomm driver. Then, when you manually update the driver, navigate (browse) to the extracted folder and click Next.
[OnePlus 8T Guides, News, & Discussion] chomsky55:
So there is no need for the MSM tool, I can just sideload OOS in the LineageOS recovery??

EDIT

Tried it and it doesnt work, gives an error status 1

I knew it was to good to be true!
[OnePlus 8T Guides, News, & Discussion] confusednoob5:
thank you. that worked. but I have a new problem. A friend told me to flash lineageOS recovery and lineage OS. then my phone worked again but I couldn't use my banking app because it detected root. i tried to install magisk and flashed the boot img. and now i have a bootloop on lineage and i don't know how to fix it. please help.

update: I think i managed to solve the bootloop. but I have the problem that my banking app checks for roots and therefore it doesn't work
[OnePlus 8T Guides, News, & Discussion] chomsky55:
Use MagiskHide
[OnePlus 8T Guides, News, & Discussion] confusednoob5:
thank you. I installed magisk and used magisk hide. it works now. thank you!
[OnePlus 8T Guides, News, & Discussion] BillGoss:
This question should have been asked in the Magisk forum, not here, as it has nothing to do with unbricking.
[OnePlus 8T Guides, News, & Discussion] TheMystic:
Have you tried using ADB or TWRP recovery?
[OnePlus 8T Guides, News, & Discussion] TheMystic:
I'm surprised that your banking app works with Magisk Hide enabled. There are apps that simply don't work on a rooted phone. There is some method they use to detect root, or an unlocked bootloader.

If an app doesn't work due to root even with Magisk hide enabled, try creating a new user in the phone (I am talking of Multi-user feature available on Android phones) and try using that app. If required, enable Phone and Message permissions for this user. I haven't tested this myself, so I can't guarantee this will work.
[OnePlus 8T Guides, News, & Discussion] TheMystic:
Congratulations! Glad to know that you can use your phone now.
[OnePlus 8T Guides, News, & Discussion] BillGoss:
How can you take a nandroid backup when there's no TWRP recovery for the 8T?
[OnePlus 8T Guides, News, & Discussion] TheMystic:
Nandroid Backup is simply a System Image, available with some custom recoveries.. It isn't a TWRP exclusive thing.

There are some unofficial TWRPs for the 8T as far as I know.
[OnePlus 8T Guides, News, & Discussion] chomsky55:
Yes to ADB no to TWRP. There is no TWRP for the Oneplud 8t as of yet.
[OnePlus 8T Guides, News, & Discussion] confusednoob5:
Sorry for posting it here. I will head to the Magisk forum.

thank you. I tried the MSM tool before I tried Lineage but I kept getting the param preload failed message and I don't know what that means and how to fix that. My only hope was lineage at that point.

thank you for that information.
[OnePlus 8T Guides, News, & Discussion] Ghriann:
A HUGE thanks sir ! I was getting mad all day long, trying to figure out why i kept getting a CrashDump after a successful download o_O Maybe it is worth to put this information in OP ? Another question, I want to go back to OxygenOS after unbrick, if I run an OTA update (to OOS 8.12) I shouldn't have anymore H2OS, right ? My device is the O8T 12GB RAM / 256 GB btw

EDIT :

So I tried to download this H202 version on my phone, and it finally booted ! From there, I downloaded a full OTA of the last OOS (from official OnePlus website), and applied it from the OS updater (local update option) and TA-DAAA, OxygenOS again 😁 For now it seems to work flawlessly, I'll update this post if I find something weird
[OnePlus 8T Guides, News, & Discussion] rikimtasu:
For those who had problem with oneplus 8t released after March 2021,this new version of MSM Tools will fix it can goes back to HydogenOS stock.After that if you prefer oxygen OS just download a update zip and update from there.

JESUS thank you so so much man you litteraly saved me so much I gave up and sent my phone to an official oneplus repair and they tried to charge me 400 bucks for their "repair" I decided to get it back and try again and found your post, I can't thank you enough truly.
[OnePlus 8T Guides, News, & Discussion] vnayrp:
worked for me... I wanted to return to stock and tried flashing all the img files manually; but in vain. So I had to turn to the MSM tool. This takes around 1100 seconds as per the time mentioned in the tool- but I got back the Phone to factory state. Bootloader gets locked once the flashing is completed. so ensure that you go back to developer options to enable OEM unlock and USB debugging to proceed with any customization.

Cheers \../
[OnePlus 8T Guides, News, & Discussion] manu4204:
I had the same issue " automatic detection of ddr failed"

I was not able to get into fastboot or recovery and the OS was constantly in a bootloop

I was able to get the device working using the following steps:

Boot the device (let it bootloop)

Ensure the device shows up properly in Device manager. (might need to disable driver enforcement in win10 )

Start the MSM tool and start and let it wait for device

Connect the device using the Oneplus cable

It should show as connected now.

Boot to edl mode using Power button + Vol up +Vol down(with cable connected)

Now the MSM tool should take care of the rest

Took me literally 10 hours to get this right. Hope this helps someone.

Cheers.
[OnePlus 8T Guides, News, & Discussion] confusednoob5:
I don't know how but suddenly it worked, I was able to go back to stock with MSM. I reinstalled the driver by unpacking it and disabled driver enforcement and now it worked. The stock OS still works the best for me. I keep having problems with Lineage :(

MSM has been running for 3400 seconds, Connected, O2, Downloading super.img to super.

It says Running:Upgrade Normal

Is something wrong here or should I let it continue? It looks like it is stuck.

If I Stop the process, what will happen to the install?

I assume but not sure that this install is destined for the inactive slot. I sure hope so. The current inactive slot has been corrupted that is why I need a new install there.

Device: OnePlus 8T with OOS "12" on active slot.
[OnePlus 8T Guides, News, & Discussion] zzjea:
I stopped the process and now I have a "Bricked" device. I get an error message that Says:

"Upgrade download failed!

This is caused by download interruption.

Recommend you use download tool again."

I get the same message over and over when pressing a button.

The device is no longer recognized by the PC. With some effort I can get it to go into Fastboot Mode, but that is all. PC can't see it however. USB debugging isn't running as nothing is.

How can I recover if I cannot get it to be known to the PC via USB?

Desperate now!!

Please give me some guidance. Thanks.

I have a crash DUMP mode , not access recovery just fastboot.

My phone was installed with K2003 K05AA , it's a intertionnal ROM.

I olso try all Global version and flash fine ( no error ) but phone reboot always with CrashDump.

This is a new phone, just receved Buy to aliexpress.

Is there a solution to force to install Hydrogen with MSM Tools ?

Ps resolved : I just succeeded by force. It is imperative once that MSM tools starts to stay pressed on the 2 volumes buttons at least 10 to 20s once the process has started to pass. If that can help someone. I thought we could release the 2 buttons once MSM tools detected the phone and started up. Now I just have to find out how to switch back to the EU Oxygen version.
