hi

Looks like I have completely F**d up the phone firmware and have no clue what version it is. I either get the Qualcomm Crashdump mode or I can get to the fastboot. If I try to flash the images from the factory OS using fastboot flash, then it complains

FAILED (remote: 'Flashing is not allowed for Critical Partitions')

The phone is bootloader unlocked...

I tried to boot to recovery using twrp and orangefox ( for all OOS 11,12, and 13) and it wont boot to recovery...

Any hints how to proceed. I am on macos, so don't have access to MSM tool, unless I get to my SO's windoze...

I am trying that now... got my kids windoze which has a USB 2.0 port

The challenge is to get it to the QCom, EDL mode... it seems to either get into crashdump mode or fastboot

Is there a way to start EDL from fastboot ?

G
[OnePlus 8T Guides, News, & Discussion] chomsky55:
I can remember it took me like 10 times before I got it working. Don't know if you can get to EDL from fastboot.

I would keep trying, fool around with different usb cables/ports and the moment you plug in the usb cable after holding vol up an down.

Hi all

Using the Firmware Flasher from Wishmasterflo, Oneplus 8t

Which one is the latest for Android 13 ? F15? F63?

Also curious about the one named F63_F15Modem. Any advantage or reason to use that?
[OnePlus 8T Guides, News, & Discussion] imusorka:
Trying to upgrade from LOS 18.1 to 20. Having flashed additional partitions and the latest recovery the phone goes into crashdump mode upon trying to reboot into recovery.

Did I mess up the sequence and now the issue is caused by an incompatibility between the partitions and my Android 11 firmware? Erasing dtbo and vbmeta does eliminate the crashdump mode but I'm still unable to boot into recovery after flashing one. It keeps on booting into fastboot.
[OnePlus 8T Guides, News, & Discussion] ghatothkach:
Is there a patched abl.img (or whatever firmware file) which gets rid of the "Orange State blah blah" device is unlocked message or is there a better way to get rid of that message ?
[OnePlus 8T Guides, News, & Discussion] Wishmasterflo:
Yes there is here. Also my flirmware flasher in my signature has the abl.img which will remove that.
[OnePlus 8T Guides, News, & Discussion] imusorka:
Update to my earlier question: I have managed to get through to recovery after switching from A to B and sideloaded the firmware flasher by @Wishmasterflo as well as LOS 20 but upon reboot to recovery (to sideload gapps) got hit with a message in Chinese and English about recovery missing. Erased everything, started over and am facing the same fastboot loop issue.

Could someone please explain what goes into what partition or should boot, dtbo, vbmeta and recovery all be flashed to both A and B? And does it matter whether any of those images are from LOS 18.1 now that I formatted data or do I want to use all from LOS 20?
[OnePlus 8T Guides, News, & Discussion] Wishmasterflo:
If you got that message then I assume that you dont have the same oos based recovery on both slots!

Make sure the recovery you use is on the same OOS base as the Firmware you flashed and have the same recovery flashed to both slots.

If you have a different OOS based recovery on one slot you will end up with that Message you got.
[OnePlus 8T Guides, News, & Discussion] xda_appreciative:
Hi @Wishmasterflo, thank you for your firmware flash tool. I got myself into exactly the same problem as @imusorka . I was following the LOS20 guide and when they said make sure you have Android 13 firmware installed I turned to your tool (emboldened by a comment above that you can jump straight to the needed firmware). Your tool needs to be side-loaded so I figured I could follow the LOS20 guide on how to sideload, so I used the LOS20 recovery. Big mistake. Now I am in the same situation as @imusorka. Please advise how to fix things? I guess I need to fastboot a new recovery.img but I don't know which one. Since adb doesn't work, I can't tell you whether I have DDR4 or DDR5 :(

@imusorka , if you have managed to come right please share what you did and steps to get to LOS20. Thank you.
[OnePlus 8T Guides, News, & Discussion] xda_appreciative:
I now see https://xdaforums.com/t/firmware-oneplus-8t-kebab-ddr0-ddr1-release-updated.4299231/post-88441631 was referring to upgrading from LOS 19 to LOS 20, not Android 11.

It seems @chomsky55 and @ghatothkach , came right, perhaps you could help too please.
[OnePlus 8T Guides, News, & Discussion] xda_appreciative:
OK so thank God, I managed to fix things a bit.

I followed a combination of the following two guides:

Update firmware on kebab | LineageOS Wiki

wiki.lineageos.org

Restore OnePlus 8T to Stock via Fastboot Commands

In this guide, we will show you how to restore your OnePlus 8/8T/8 Pro to stock OxygenOS by flashing it via Fastboot Commands and unbrick it.

droidwin.com

but only to undo the three partitions that I flashed following the LOS 20 guide (and NOT the DDR partition)!

I think this only worked because the other partitions happened to match the stock rom that I downloaded directly from oneplus.com .

Now I can boot into Android 11 and I can check my DDR! Hooray its DDR5!

So now I would like to follow @Wishmasterflo 's method of flashing to the latest firmware for LOS20.

The question is how do I do that with Stock recovery? Thank you.
[OnePlus 8T Guides, News, & Discussion] Wishmasterflo:
No stock recovery can not do that. You need to boot some custom recovery and adb sideload the firmware zip file once.
[OnePlus 8T Guides, News, & Discussion] xda_appreciative:
Ah, I see. @Wishmasterflo since you are my trusted expert, let me use OrangeFox! Ok I've got OOS 11 OrangeFox working, let me try and sideload fw_Oneplus8T_EU_OOS13_F63.zip . Similar to someone else's question above, I don't know what to make of these Fxx numbers? How come they jump from 15 to 62/63? What is 63_F15modem?

Thank you!
[OnePlus 8T Guides, News, & Discussion] Wishmasterflo:
Those F numbers are just the OOS13 Updates from Oneplus. I dont know why there is a so big gap in the numbers sometimes. Perhaps depends on how many things are added from Oneplus side in those Updates.

I build a Firmware file for latest F63 with the modem file of F15 Firmware. It seems that for many poeple the Internet speed was worse on the F62/F63 firmware, so using tghe Modem file of F15 gets better Internet download speed for many poeple.
[OnePlus 8T Guides, News, & Discussion] xda_appreciative:
Thank thank you @Wishmasterflo, I am up and running with LOS20!

OrangeFox worked for sideloading your firmware update zip!

In terms of hiccups: I had the problem that OrangeFox flashed to recovery (using OrangeFox) subsequently killed booting into Android 11 (before I updated the firmware). Nevertheless, I proceeded. I also had another problem: enabling ADB sideloading did not work :/, but copying the zip across to the SD card and installing it from file manager did. Phew. After I got the firmware installed, I switched completely over to following the LOS20 guideline (at first I was tempted to try and use OrangeFox to install the ROM, but then the OrangeFox wiki suggested following device specific guides especially for A/B devices, which I then decided to do).

Anyway, thank you so so much for both OrangeFox and your Firmware updater! This has been the scariest and most difficult custom ROM install I have done!
[OnePlus 8T Guides, News, & Discussion] kevinco1:
So your flashable F63 firmware actually contains the modem of F15?
[OnePlus 8T Guides, News, & Discussion] Wishmasterflo:
I have both Versions, one normal F63 one and one with the Modem file from F15.
[OnePlus 8T Guides, News, & Discussion] kevinco1:
Ah, just saw that in the F63 folder on Mega, thanks!
[OnePlus 8T Guides, News, & Discussion] imusorka:
@Wishmasterflo I'm experiencing some speed issues here too. Is it safe to reflash F63 with the one that includes the F15 modem? As in, on top.
[OnePlus 8T Guides, News, & Discussion] Wishmasterflo:
Yes
[OnePlus 8T Guides, News, & Discussion] imusorka:
@Wishmasterflo Thank you. Is it known whether OnePlus will release any other firmware updates for 8T?
[OnePlus 8T Guides, News, & Discussion] Wishmasterflo:
Yes the Oneplus 8T is still getting new OOS Updates from Oneplus which can be used to build updated Firmware files from.
[OnePlus 8T Guides, News, & Discussion] loosecannon2013:
T-Mobile is taking so long with the bootloader unlock code, is there anyway to keep dual sim on 8T 5g T-Mobile when updating to OOS 13 .63 as i am still on the beta build. Only way i can keep dual sim working...
[OnePlus 8T Guides, News, & Discussion] Wishmasterflo:
Yes is you flash my OOS13 firmware from custom recovery it should get you dualsim enabled.
[OnePlus 8T Guides, News, & Discussion] loosecannon2013:
hey buddy thanks for replying but how can i flash anything without my bootloader unlocked, can u please send me a link or guide on how to flash the custom recovery and your OOS firmware please
[OnePlus 8T Guides, News, & Discussion] Wishmasterflo:
You need to unlock your bootloader in order to flash or do adb sideload from a custom recovery.
[OnePlus 8T Guides, News, & Discussion] loosecannon2013:
Thank you again, as i'm trying not to get stock in any bootloop and not seeing this question while searching for my device can you give me more info on the sideload and flash please, if i'm not asking for to much.
[OnePlus 8T Guides, News, & Discussion] Wishmasterflo:
You just boot into a custom rom recovery or use Orangefox/TWRP from fastboot with fastboot boot recovery.img

Then you enable adb sideload in recovery and open cmd on your Computer and type adb sideload and then the zip file you want to flash.

Download latest adb and fastboot before proceeding.
[OnePlus 8T Guides, News, & Discussion] loosecannon2013:
cool thanks, again all this is done by not unlocking my bootloader right
[OnePlus 8T Guides, News, & Discussion] Wishmasterflo:
Yes unlocking Bootloader is the first step.

Guess you can follow this

And here you habe the latest adb and platform tools for Windows.
[OnePlus 8T Guides, News, & Discussion] loosecannon2013:
then i'll have to wait for the bootloader unlock token from oneplus. I contacted tmobile and they said they don't unlock bootloaders
[OnePlus 8T Guides, News, & Discussion] imusorka:
@Wishmasterflo I have a persistent notification about KB2005_13.1.0.513(EX01) but nothing happens when I tap it. Is this new firmware and I want to wait until your tool is updated?
[OnePlus 8T Guides, News, & Discussion] Wishmasterflo:
What do you mean with persistent notification? Are you on OOS13 now or? That 13.1.0.513(EX01) is OOS13.1 upgrade I guess. My firmware is already updated with OOS13.1
[OnePlus 8T Guides, News, & Discussion] imusorka:
@Wishmasterflo I am on your latest but got that notification a few days ago and it doesn't go away. Has new firmware been pushed by OP recently?
[OnePlus 8T Guides, News, & Discussion] Wishmasterflo:
If you are on OOS13.1 now then that is the latest Version. Dont know why you get that notification then but that is from offical OOS13.1 and has nothing to do with just the Firmware.
[OnePlus 8T Guides, News, & Discussion] imusorka:
@Wishmasterflo I'm on Lineage 20 (20230420 nightly).
[OnePlus 8T Guides, News, & Discussion] Wishmasterflo:
Hmm? But on linage you will not get any notifications about oos updates.
[OnePlus 8T Guides, News, & Discussion] imusorka:
@Wishmasterflo Puzzled by this too. Hopefully it goes away when I update LOS.
[OnePlus 8T Guides, News, & Discussion] Brasscat82:
I have a KB2007 (US-TMO) running LOS 19 (A12)

Bootloader Unlocked, Rooted

I would like to upgrade to Global A13 and keep root.

From what I am reading I need some confirmation and advice to do this.

1. After reading, I believe i should downgrade to A11, unlock the bootloader (again) using the Unlock Bootloader toggle under Dev. Options and ADB "OEM Unlock.". Is this correct, or will I need another unlock key to keep the Bootloader unlocked??

2. After achieving bootloader unlock in A11, I should I take the OTA to A13, and I should still have the bootloader unlocked, correct?

3. Then, I can patch the boot.img after upgrading to A13 to gain root again, correct?

Thanks for any help/answers you can give, fam!
[OnePlus 8T Guides, News, & Discussion] Wishmasterflo:
You dont need to downgrade to OOS11/Android11, if you have a unlocked bootloader now you can just boot like Orangefox recovery, and flash the full OOS13 OTA zip file in Orangefox.

Then for root, you just install Magisk from the Orangefox addon menu.
[OnePlus 8T Guides, News, & Discussion] Brasscat82:
Thank you for the quick reply!

Forgive me, I haven't done this in a while, just a couple of questions about OrangeFox, since I've never used it.

I don't really want to install a custom recovery on the phone permanently as I will be switching to LOS ROM once the firmware is updated, which has its own recovery for installing OTA updates. Will running OrangeFox in ADB allow me to root without installing OrFox on my phone? Or would it be better to patch with Magisk and flash it in that case?
[OnePlus 8T Guides, News, & Discussion] Wishmasterflo:
If you dont want to flash it to your phone then just fastboot boot the Orangefox.img file from fastboot/bootloader.
[OnePlus 8T Guides, News, & Discussion] Rootk1t:
Wouldn't be easier to update stock OOS files to 13.1 via firmware flasher (link is in Wishmasterflo signature) and then update LOS to the latest one?
[OnePlus 8T Guides, News, & Discussion] Brasscat82:
I don't know. Again, I haven't done this for so long, I'm a little confused as to which way would be best/easiest.

I was going to use the MSM tool to switch to global 11, as I've read that 13 will relock the bootloader and want a key. That's why I was going to downgrade to 11; unlock the bootloader again, then upgrade to 13 OTA before switching to LOS20 ROM

[OnePlus 8T Guides, News, & Discussion] bin/bash:
I get the same message on LOS 20. Did you find out what caused it? Did it go away updating LineageOS or firmware?

Another question: There used to be a large battery drain when using modem.img from any firmware later than F15. Any experience with latest firmware? Still the case?

If yes, it is possible to replace modem.img from the latest firmware with the modem.img in F15 using wishmasterflow's firmware flasher, right?
[OnePlus 8T Guides, News, & Discussion] Mugenski:
Hey all,

I'm on an old TMO device that was changed to kb2005 (I seem to recall a modem flash?) and I'm now on OTA 13.1.0.582 unlocked and rooted.

In the mega repo I see NA 580 and IN 582. Which should I be using? Just want to confirm that IN is international and not India. Safe to flash that modem too? I'm currently on Q_V1_P14 but I'm having a hard time remembering how I got to that modem and where it is from.
[OnePlus 8T Guides, News, & Discussion] BillGoss:
IN is, in fact, India and it's KB2001. NA is North America and it's also the global version - KB2005.
[OnePlus 8T Guides, News, & Discussion] Mugenski:
Thank you for the clarification Bill.

Considering I am NA/Global on .582 would it be alright to flash the .580 firmware or should I be looking for the NA .582 specifically? I only see IN as having .582 and don't know what is differentiating them. Perhaps there were no firmware updates between the releases?
[OnePlus 8T Guides, News, & Discussion] BillGoss:
Can't help you there.

But if everything is working fine with your carrier on .582 then I would leave things are they are.
[OnePlus 8T Guides, News, & Discussion] Wishmasterflo:

[OnePlus 8T Guides, News, & Discussion] chenxuwen:
Very weirdly, this post

https://xdaforums.com/t/oneplus-8t-firmware-updates-for-custom-roms.4298181/

[OnePlus 8T Guides, News, & Discussion] Nixsuki:
Even the lead developer of the Xiaomi Firmware Updater doesn't develop unified due to region classification to give users option to choose firmware based on their current device region.
[OnePlus 8T Guides, News, & Discussion] chenxuwen:
So it is that complicated? So same os could have different version numbering dur to region or updater. Oneplus really don't want anyone to understand them then.
