You can delete/recreate virtual partitions using:

fastboot delete-logical-partition name_slot
fastboot create-logical-partition name_slot 100000

and then flash the partition.

Since the latest firmware upgrade my SIM-cards are constantly dropping connections. It will switch from 5G to 4G and back endlessly, then crash and go offline alltogether. I already did a complete MSM restore, but it's still happening. So, I want to downgrade firmware again to see if this helps, because I never had any modem problems with older firmware.

Is it safe to downgrade firmware ONLY? I'm afraid of breaking my IMEIs.

This is a pretty widespread issue btw, theres a 16 page thread on OPs own forum and countless reddit-threads about this...

Thank you for packaging firmware for the users running custom ROMs. Saves people so much time instead of upgrading firmware by flashing latest OOS , then back over to custom ROM.

I have a oneplus8t United States unlocked , I believe this would be the kb2005 ?

Reading through the thread, My understanding is that you cannot package 11.0.8.13.KB05AA? Which would be the latest for oneplus8t global , correct?

[OnePlus 8T Guides, News, & Discussion] hightech316:
Where exactly can one review their current firmware version on AOSP ?
[OnePlus 8T Guides, News, & Discussion] BillGoss:
You can look at the timestamp near the end of /vendor/firmware_mnt/verinfo/ver_info.txt and compare to the timestamp in the version name - it will be close though not identical.

For example:

The timestamp in the firmware version of 11.0.11.11 Global is 2110091944 (15.O.29_OTA_0290_all_2110091944_3d8159dff77f4ef1)

The timestamp in ver_info.txt is "Time_Stamp": "2021-10-09 19:54:37"

They differ by about 10s.

You might (I don't know if this works on custom ROMs) also be able to check getprop persist.vendor.op.last.version.ota

Note: /dev/block/bootdevice/by-name/modem_x gets mounted on /vendor/firmware_mnt so ver_info.txt is actually a file in the modem partition.

No need to flash separate firmware files?
[OnePlus 8T Guides, News, & Discussion] azoller1:
Custom ROMs only flash to rom specific partitions, so it will not update other firmware that a full OOS update would flash to. So, if you never updated to the latest OOS when running stock before flashing a custom rom, you should flash the latest firmware zip posted here.

My teacher told me that there is no such thing as a stupid question... So I want everyone to keep that in mind... What is the difference between LPDDR4X and LPDDR5.... I bought my 8t when they 1st came out and I have LPDDR4X.. Is LPDDR5 just faster newer hardware? Did it come out on the later builds of the 8t or is it a random thing that customers get two different types? Honestly If LPDDR5 is better in anyway then LPDDR4X... Then being a customer... Honestly pisses me off.. a little.. I mean I'm not going to do **** about it.. but I will think on inside of my head... That's kinda f*cked.. if it's the same product it should all have the same hardware... Am I the only person thinking this?

[OnePlus 8T Guides, News, & Discussion] rohanhole:
This is a firmware update not the whole system ( os ) update. You need to update zip via twrp and good to go. Dont think about A/B. Just make sure you download the correct zip.( chech OP for ddr0 or ddr1 ) and thats it.
[OnePlus 8T Guides, News, & Discussion] Rootk1t:
IMHO, OnePlus switched to LPDDR5 because it's cheaper to buy it for them, than LPDDR4X.

Also chip shortage and supply problems may lead to it too.

I don't think you'll notice the change in real use cases.

[OnePlus 8T Guides, News, & Discussion] ..Cory..:
So I've been waiting for this to be updated to the latest global release... But I'm getting a little impatient hahaha

Can anyone point me to where I can download the latest global release to convert from the US TMobile shipped version? I'm already rooted with unlocked bootloader and SIM, just been a little outdated.
[OnePlus 8T Guides, News, & Discussion] RainGater:
Ok, it looks like @Nixsuki has moved on from 8T. Since no one was releasing the firmware update package, I took the liberty to download the latest global firmware from OP site and extracted the payload.bin using payloaddumper.

I compared it with the previous version and it looks like nothing changed as far as firmware is concerned and details are in the picture.

In the future, if you want to do this, follow this simple guide:

Download the latest ROM from OP or OxygenUpdater - https://www.oneplus.com/global/support/softwareupgrade/details?code=PM1605596915581

Extract the file, payload.bin, from the downloaded ROM zip.

Download payload-dumper-go from https://github.com/ssut/payload-dumper-go

From a command prompt, run the following command, which will extract all the img files and will be stored in a folder named extracted_<timestamp>:

payload-dumper-go payload.bin

Open the previous firmware zip file and replace the files from the firmware-update folder with the extracted files.

Compare it, flash, and enjoy the latest firmware. :)

PS: For DDR_1, use these files from the downloaded ROM zip:

xbl_config_lp5.img

xbl_lp5.img

For DDR_0, use these filess from the downloaded ROM zip:

xbl.img

xbl_config.img

[OnePlus 8T Guides, News, & Discussion] pinkmallow:
Hey there!

Firstly, thanks for the service, OP!

Just to be safe, I want to ask some questions, since I'm new to all this and I don't want to lose my daily driver.

Do I have to backup anything before I flash the new firmware? - if so, what?

Is there any possibility that I may lose my IMEI or something similarly important?

I'm on the Chinese version KB2000 but global ROM now. Will there be any changes if I flash the EU version (e.g. accessible frequency bands, or KB2005 as model name?)

Have I overlooked something essential?

I'm sorry for these questions, but since I hard bricked my daily driver 2 years ago, I became much more careful/anxious when it comes to flashing anything. ^^

Thanks in advance :)
[OnePlus 8T Guides, News, & Discussion] chenxuwen:
Should KB2000 use EU or global?

After flashing the newest EU firmware, the baseband is 4-00028-sdx55_rmtefs_pack-1.418912.1.432109.1 in case one wonders if one is already at the newest version or not.
[OnePlus 8T Guides, News, & Discussion] Nixsuki:
No need to backup. If want to flash custom ROMs and come from the latest OOS 11 Both slots its okay. Custom ROMs requires latest OOS11 firmware.

You can update till I update the latest OOS11 or 12 in future.

Flash and reboot 😊

ANNOUNCEMENT!​

Firmware based on OxygenOS 12 is coming this few hours to all models and regions of OnePlus 8T. Due to new firmware naming format from OPPOfied OxygenOS 12, you must know your device Model & Region codes.

KB2000 - Chinese Model

KB2001 - Indian model

KB2003 - European Model

KB2005 - North America Model

For user information: Firmware depends on what country you are and those frequencies retained as per your device model, no matter what model is your device is.

Example: My device is KB2000 which Chinese model and in the first place it is Global flashed by KB05AA Global firmware and I'm living in the Philippines, it is okay to use KB2005 firmware which is Global.

2nd example: If your device is KB2003 which is EU model some times these device uses 2 firmware which is KB05BA or KB05AA it is okay to us EU or Global firmwares same as Indian model.

Additional Note: To those who are new comers or newly to custom rom environment. These firmwares are essential for your custom rom of choice. This should be flash along with your rom + gapps. Being in the updated firmware fix and optimize your custom rom experience.

After I flashed this (ddr0), it keeps booting back to fastboot. Also, it shows the Product_name as kona. Shouldn't it be kebab?

I power it down and turn it on and goes to fastboot.

Any ideas?
