[FIRMWARE] OnePlus 8T [kebab][DDR0/DDR1][Release Updated!]

Why necessary to check ddr type?

It will hardbrick the phone if you flash wrong files.
DDR4x and DDR5 have different working voltages.
So appying DDR4 voltage configs to DDR5 modules may permanently damage them.

I flashed the C.36 fw on my DDR0 KB2003 today and might as well share -

easyupload.io

easyupload.io

easyupload.io

it is based on one of OPs previous zip, I just replaced the IMG files from the latest payload. seems to work no problems, data connection took a minute or two to establish that's about it.
baseband version remains same

upload place picked at random so I'll provide md5 hash:
6a6203505d90fdc801990abef074f62b

Nice.

This is what I do also. I have a set of scripts to automate the whole deal, and I can confirm that your zip is sound. MD5 is correct, and all the files in "firmware-update" folder are indeed from the latest C36 for KB2003 with DDR0 flavour.

The icing on the cake is to edit "/META-INF/com/google/android/updater-script" so that the info header reflects what is actually in the archive, and add a little explanatory output during the flashing.

Your zip and mine are bitwise identical in every respect apart from that file, near the top where I added

# Extracted from KB2003_11.C.36 for DDR0
# Repacked 30/10/2022 by denisovich

ui_print("Flashing KB2003_11.C.36 firmware for DDR0 ...");
ui_print("... extracted and repacked 30/10/2022 by denisovich");
ui_print("");

If its brick to 9008 then still able to recover but if lose 9008 then nothing to do

I took a look into some OTA files from OOS13 because I wanted to check what files are existing there and which are different.
When comparing the files from OOS13 and OOS12 I could see that the below ones are not existing in OOS13:

featenabler.img
mdm_oem_stanvbk.img
multiimgoem.img
spunvm.img
xbl_config_lp5.img
xbl_lp5.img

So there I could only the see the files xbl_config.img and xbl.img but not the ones with lp5 for DDR5 RAM so I wonder how it is determing what to use for DDR4 and DDR5 ????

I did the same test
But in my case OOS 13 has exactly the same set of files as OOS 12.
I got my version of the ota from https://android.googleapis.com/packages/ota-api/package/e61f1cf7c6a55e531113091deadfb7acb96901da.zip

PS: since OOS 12 the DDR type of the phone is available from cat /proc/devinfo/ddr_type (need root access).

Hi!

OK thanks. Let me check again.

Hmmm strange. I downloaded the same file and extracted the payload.bin with payload dumper but I dont habe these mentioned files. So for me I dont see the different files needed for DDR4 and DDR5 and the other ones I mentioned above I dont have from that OOS13 file.

 

[kartikeya98]

So I am really confused I am on PE12+ which is based on OOS11 now I want to move to PE13 which is OOS12 based rom.
that means i need to update the firmware to C.35 or C.36. I dont want to use MSM tool to do so. i read that it is possible to update the firmware by flashing them using adb sideload. but then i read that you need recovery with same version as firmware. so what do I do i mean right steps as i dont wana brick my device

 

[trance89]

You don't need to, just follow these few steps: https://wiki.lineageos.org/devices/kebab/fw_update
C36 fw files were linked earlier in this thread or just use payload-dumper-go to extract them from full C36 OTA
You can't brick your device if you flash the correct fw files (DDR4/DDR5)

Is the version you linked OOS13? If so, which variant?

FYI

I just created a new Firmware Flasher script for Oneplus 8t and 9r which will automatically detect the RAM type of the phone and flash the correct Firmware files, also it will abort the flashing procedure if it can not detect the RAM type by some reason.
Will need to adjust some few things there but then I can share a download link to my updated flashable Firmware files.

- Initial Version of the updated flashable Firmware script for Oneplus 8 series and Oneplus 9 series
- OOS13 Firmware files are using abl.img from OOS13 F10 to remove the yellow bootloader message
- Flasher should support Firmware flashing from all OOS12 and OOS13 Versions (OOS11 is not supported now!)
- added automatic DDR RAM type detection
- Flasher will terminate if it can not detect the correct RAM type by some reason
- added a check that the Firmware flasher is flashed from recovery only
- added device check that the Frimware is flashed on a supported device
- Updated info that the Firmware is getting flashed to both slots (A and B)

P.s. Will do some final adjustment to the script and then upload and provide a download link for this.

This tool looks great! Perfect timing for me to find as I'm looking to update my 8t to LineageOS 20. Pardon my ignorance, but what is the difference between the F13 and the F15 firmwares?

Just search on the Internet. I dont have in mind now what exactly the Changelog from Oneplus was for OOS13 F13 and OOS13 F15.
