[OnePlus 11] ChrisFeiveel84:
what if the device is already on a new android version? if the old build is then flashed, the op11 will not boot because there may be cow partitions that need to be deleted
[OnePlus 11] nonegor:
No problem of me, I use A06 to flash but I currenly A07
[OnePlus 11] TweetyPeety:
thanks, checked, no cow partitions on the device. Switched now the active partition to a I will try to install it on A and B and try it again, strange behaviour.

Doesn't matter what I flash it stays always in this version. Why?
[OnePlus 11] ChrisFeiveel84:
You have no Update maked after a Update you have cow partition
[OnePlus 11] ChrisFeiveel84:
this is very strange because if you flash the eu a08, for example, you should also boot in the eu (CHP2449) afterwards
[OnePlus 11] TweetyPeety:
I know, it is really strange. And I done it yesterday with a guy who unbricks devices, some Indian special account guy, showed him the whole process and made pictures. Wait can add it.

There you see the right payload.bin, flashing in FAstboot, OK, flashing in FastbootD, OK, flashing the radio/oplusstanvbk.img from Color OS, OK, after that I even wiped data, OK, booting into System. STILL A06.

So strange and the most strange part. I read here all the time, OXYGEN OS, OTA update breaks the device but got a friend now, he bought a device from Giztop with A07 and asked them. They said at the beginning they had problems, now all fine. And his 2447 A07 devices showed an update A08 and it updated, no problems, no brick, everything fine.
[OnePlus 11] sunxutian:
Does auto brightness work on his oxygen os? Bootloader locked or not? Did he take incremental or full OTA?
[OnePlus 11] TweetyPeety:
just normal update, so it is an incremental and bootloader is locked. But I can't reproduce it with my device, I can't even update on A07
[OnePlus 11] Danz17:
Anyone tried OTA A08 update from A07 yet ?
[OnePlus 11] sunxutian:
I did, same you need to flash oplusstanvbk.img after ota and same issues still exist asA07
[OnePlus 11] Danz17:
Aside from nfc not working and screen dimming issue at times, I don't have any other issues
[OnePlus 11] sunxutian:
My NFC works, but scroll screenshot doesn't, all black
[OnePlus 11] Jason_Lim:
when you mentioned flash, how you flashed it ya?

1) is this oxygen A08 global or eu ?

What CPH is it ?

From the Guide Step 1 is the below file name

CPH2449 Global A07: eea73728a1b945ea8e3ff6b628495af5.zip

The Oxygen A08 is ecc94834acf24f1caa5968555b0b4b16.zip.

is it the same though?

as the guide is eea, and Oxygen A08 is ecc

2) when you mean by the last a10 build ?

means a11 is coming out soon?

3) is it okay if the color os is A10 build and the Oxygen is A08?

As the firmware is different?

4) for this full ota pack, i unable to download the ota directly from phone setting,check for update and use the local oxygen update right ? (as it will brick the phone)?

how should i update the newer oos version and the security patches then?
[OnePlus 11] ChrisFeiveel84:
1: is eu No global oos 13 A08 build link here ( global and eu have the same cph2449)

2 this is the build Nr (last update)

3 is coloros a13 a10 build (a10 is the build nr)

4 on a converted device I speak of an update via FBE and not via an internal updater then this here is for convertet phone )
[OnePlus 11] Jason_Lim:
sry, i still abit blur on number 1, :(

- what do you mean by is eu No Global oos 13 A08?

- and Does this link https://gauss-componentotacostmanua...23/03/03/ecc94834acf24f1caa5968555b0b4b16.zip

[OnePlus 11] TweetyPeety:
Ok, Feedback. Got now 4 devices, a flash script from China and got all 4 devices, which had 2447 A06 and never was shown an update, got now all to 2447 A07. Easy, worked, no problem. All 4 devices show A08 update, clicked in just in the os, 2 updated without problems to A08 and 2 don't want to update. Goes to 100% and than error, please download again. Tried 10 times, no, they don't want. Strange behavior.
[OnePlus 11] ChrisFeiveel84:
The link for oos13 a08 is the eu build (eu -eea.

global is glo ) View attachment 5863463View attachment 5863465
[OnePlus 11] TweetyPeety:
but did you update with OTA to A08 or with the flash there ? From A07 ? A06 or straight from Color OS? And does OTA maybe work?
[OnePlus 11] ChrisFeiveel84:
I have an eu devices and have it with oxygen updater Updatet (other with china devices have it Updatet with fbe and the full ota pack for eu oos 13 a08) over fastbootd
[OnePlus 11] TweetyPeety:
Ah OK EU device, we are more about China device
[OnePlus 11] Jason_Lim:
oh you have an EU device,

for my case is i having China Version, and want to flash from Color OS to Oxygen OS.

Which means I will need the CPH_GLO - international version right ??
[OnePlus 11] Jason_Lim:

where do get the Oxygen OS 13 for Global not EU ?
[OnePlus 11] kaijern:
it was in my post first page. search from https://yun.daxiaamu.com/OnePlus_Roms/一加11/
[OnePlus 11] Jason_Lim:
fastboot flash --slot=all oplusstanvbk radio/oplusstanvbk.img

Is this step consider flashing on partition A and partition B ?

After this final steps,

how to lock back the bootloader without bootloop ?
[OnePlus 11] kaijern:
did u actually read the post ?

fastboot flash --slot=all oplusstanvbk radio/oplusstanvbk.img <-- both slot, it says all.

the lock got nothing to do bootloop. boot loop is caused by oplusstanvbk.img.
[OnePlus 11] Jason_Lim:
fastboot flash --slot=all oplusstanvbk radio/oplusstanvbk.img <-- both slot, it says all.

a) So after I done the above (1),

I run in platform tool Command Line (cmd) Fastboot flashing lock ?

b) Does the version matter? the A07 A08 A09?

For example Oxygen OS 13 A08, then using Color OS 13 A09?

c) I now downloading Oxygen OS 13 A07. ( not sure if A08 able to download or not)

and Color OS 13 A07..

It's okay ?
[OnePlus 11] kaijern:
just use the latest. ColorOS A10, oxygen A08
[OnePlus 11] Jason_Lim:
fastboot flash --slot=all oplusstanvbk radio/oplusstanvbk.img <-- both slot, it says all.

a) So after I done the above (1),

I run in platform tool Command Line (cmd) Fastboot flashing lock ?

b) would also like to wonder,

if i locked the bootloader with flashed OxygenOS, if newer Oxygen 14 came out, how do I install the Oxygen 14?
[OnePlus 11] ChrisFeiveel84:
When you lock your bl and on china op11 with oos flashed you will have a problem when the next Update cams out than you can after you make the Update not flash the coloros oplusstanvbk.img

And have a bootloop
[OnePlus 11] nonegor:
what is fbe?
[OnePlus 11] sCRIPTPER:
maybe fastboot enhance
[OnePlus 11] Jason_Lim:
yeah but locked blootloader for banking apps..

was wondering if

fastboot flash --slot=all oplusstanvbk radio/oplusstanvbk.img <-- both slot, it says all.

a) So after I done the above (1),

I run in platform tool Command Line (cmd) Fastboot flashing lock ???
[OnePlus 11] Nzol Tan 1211:
Hello,

Step 3:

Make sure fastbootd is NO (Phone Screen: The one with Menu and shows SECURE BOOT/DEVICE STATE)

Step 4:

Make sure fastbootd is YES

Is there any picture that show step 3 and step 4 on the fastbootd is NO and fastbootd is YES??

As I am not sure on how to confirm with fastbootd is NO or YES ?

hmm i downloaded both oxygenOS 07 and ColorOS 07, but it's different zip file name though.

btw I have downloaded both oxygenOS A08 and ColorOS 08, and unzipped.

But both showing only payload,bin. I unable to find the radio folder in ColorOS 08 ? (radio/oplusstanvbk.img)?
[OnePlus 11] jarodlau:
You need download OFP image
[OnePlus 11] Jason_Lim:
I am using this ->Following is the steps to flash the OTA updates:​

1) hmm, but i am using the OTA updates guides??

2)​

Get the firmware from this post

Firmware also availble at https://yun.daxiaamu.com/OnePlus_Roms/一加11/

i searched for these 2 url, with all the different version (a07,a08,a09, OFP or OTA)

but still doesn't find the same zip file name as OP guide tho :(

​
[OnePlus 11] jarodlau:
They don't be the same, you can flash 07,08 oxygen, whatever you wanted.
[OnePlus 11] kaijern:
I got so fedup and decided to goto HK and get my OnePlus 11, a real CPH2449 GLO. Paid and waiting to collect.

I will not be update and maintaining this post from now on.

Why give up?

Minor issue like auto brightness and things is still something i can live along with.

Some othe rmajor issue are just impossible to make this chiniese converted 1+11 to be my daily driver:

- Auto reboot randomly

- Lagging randomly, screen lag, video recording lag.

- OTA update issue, refreshing/reinstall at every update is just anonying

My advice? just get a proper non chinese version or if you own a Chinese version just stick with colorOS.
[OnePlus 11] Jason_Lim:
If stick to ColorOS,

How to install Google services and uninstall the china pre-installed apps ?
[OnePlus 11] ChrisFeiveel84:
google services build in you need only to install google play store (no android with aout google services build in since a10 ((project mainline ))

and the china apps you can disable /uninstall with adb ( adb app control)
[OnePlus 11] Jason_Lim:
Step 5:

fastboot flash --slot=all oplusstanvbk radio/oplusstanvbk.img

- After this last steps, can i run the cmd , fastboot flashing lock?

So that it wont go into bootloop ?
[OnePlus 11] nonegor:
agree

sometimes the screen lag, I need to switch off the screen and wake up the screen again
[OnePlus 11] tonyp64:
I'm a noob. I have a converted Chinese Oneplus11. I am on Cph2449.06. What do I need to do to update to CPH2449.08. I don't want to brick the phone again. I will appreciate any help or suggestions.

Thanks,

Tony
[OnePlus 11] ChrisFeiveel84:
The Update pack and the image from coloros

(oplusstanvbk.img from coloros 13 a10 build )
[OnePlus 11] tonyp64:
Are the instructions somewhere on how to do this?
[OnePlus 11] ChrisFeiveel84:
Make the Update and after the Update flash the coloros image over fastboot /fastbootd
[OnePlus 11] Nzol Tan 1211:
which means need to do the same process from Step 1 to Step 6 all over again , if that's a new Version exp CPH2449 A.11?
[OnePlus 11] kaijern:
more or less yes. that's why i give up on the chinese version.
[OnePlus 11] Nzol Tan 1211:
what's the benefit and disadvantage of ColorOS and OxygenOS though?

I see that the ColorOS using QHD, the battery degrade quite quick
[OnePlus 11] nonegor:
colour os has many preinstalled chinese apps and chinese news

also, you need to install play store by yourself
[OnePlus 11] nonegor:
the img need to be flashed in fastboot?

i only flashed in fastbootd
[OnePlus 11] brystfire08:
Hello. Is there a guide like this to go back to coloros? Got mine from China and it's flashed to Global rom 2451.
[OnePlus 11] Nzol Tan 1211:
Oh,

do you which colorOS system app can disable, as lots of bloatware though.
[OnePlus 11] nonegor:
I just flashed to the oos, i don't use cos
[OnePlus 11] RB Rodro:
thanks sir device sucessfully convert to OxygenOS 13.0.0 A.07

but i did not unlock the bootloader after the device worked.

will this cause any problems ?
[OnePlus 11] nonegor:
you should keep your phone unlocked in order to update the OS without brick
[OnePlus 11] Canuck Knarf:
Ok I have been playing around with this OP11 PHB110 converted over to oxygen Android 13....keep getting boot loop.

First thing dont change a to b.. what ever slot you on ..leave it ..I have tried cause of Black state and MSM can't read ( I have one phone in) ..

Now I had phone just boot to fastboot...wont boot to recovery...just fastboot .. " what is good thing." ....What i did to get so I could at least have recovery " fastbootd " I was flashing in fastboot with these img files

Step 3:

fastboot flash --slot=all modem radio/modem.img

fastboot flash --slot=all boot images/boot.img

fastboot flash vbmeta_system_a images/vbmeta_system.img

fastboot flash vbmeta_system_b images/vbmeta_system.img

fastboot flash vbmeta_a images/vbmeta.img

fastboot flash vbmeta_b images/vbmeta.img

fastboot flash vendor_boot_a images/vendor_boot.img

fastboot flash vendor_boot_b images/vendor_boot.img

fastboot flash vbmeta_vendor_a images/vbmeta_vendor.img

fastboot flash vbmeta_vendor_b images/vbmeta_vendor.img

Your phone will reboot to recovery " fastbootd"

Once that is done.. reboot phone to fastboot

Open up fastboot enchance . do the normal ...check for cow files...delet if any . check mark unknow partitons

Flash newest payload ( I'm using CPH2447_ 11_A.08)

Phone will almost start oxygen os but reboot. GO back to fastboot flash the " oplusstanvbk " from the Adandon_PHB110 . I use " fastboot flash oplusstanvbk " . your phone should boot up.

This worked for me
[OnePlus 11] danrch0829:
I cant enter fastboot (volum+ and power button doesn't work), only recovery mode, when I check out device manager, it doesn't even show device, should go through 9008 with MSMtool?
[OnePlus 11] sefai77:
What order did you do the process in? I wanted to do it too, my phone is bricked
[OnePlus 11] ChrisFeiveel84:
Msm (edl modus) is power off and press and hold pressed voll+ and voll- and put in the usb the op boots to edl (msm tool only works with auth)
[OnePlus 11] Canuck Knarf:
There's a difference from boot loop or bricked...bricked is no power black screen...push all three buttons ,have device manager open it will come up under ports if your have 9008 usb drivers installed...boot loop will shut your phone off....it waits a few minutes and tries to start up...you may have to hold all three buttons until you feels it vibrate...release buttons and it should enter fastboot..or I heard of just recovery...this is a ok thing ...fix able..

Hard bricked sometimes MSM can't read the phone and it will fail...need to send back for repair.
[OnePlus 11] ChrisFeiveel84:
I have never saw a hardbricked op that you can not boot to edl

The problem is on all op devices (and other ) that the phone goes out from edl mode when you not holt the two buttons (vol+ and vol- ) after 10-15 secends

When you hold pressed this two buttons the op reboot after 10-15 secends back to edl mode
[OnePlus 11] Canuck Knarf:
Thats right you will always have edl...Now MSM reads and and writes...If you have totally bricked...wiped everything off phone your MSM will Always stay at 3% and fails after 30 to 36 seconds...Needs to be sent back or unless they come out with 9008 line bush save brick file

I have MSM and one totally bricked OP 11...had two other peeps try with MSM..both say Its totally wipe..needs to go back.

The OP 10 pro has jumper point when totally dead , you my have to jump them out in order for MSM to work . OP 11 I cant find the jumper point ..Yet
[OnePlus 11] ChrisFeiveel84:
so that everything is deleted from the op11, a critical partition has to be unlocked, which most people don't do, since most only unlock the bootloader

The msm tool has already read older oneplus phones first (like the param partition) and only then flashed. and in order to delete the param partition, it must first be critically unlocked, otherwise it will be locked
[OnePlus 11] ChrisFeiveel84:
Have you a pic from op11 motherboard ?
[OnePlus 11] Canuck Knarf:
You can say anything you want...but if you have a totaly bricked ..MSM anit helping you.. Hold On I get pic of Mother board for you
[OnePlus 11] ChrisFeiveel84:
I have no bricked op11 (i use no root and no bootloader unlock )
[OnePlus 11] Canuck Knarf:
Here you go. I wish there was a J- Tag cable to jump start it or something ... I heard OP service peeps have a cable to do this through the USB and phone...!!

I made a cable with a reset button on it between the green wire and ground on the cable it will reboot phone from charging mode to file transfer mode...or it will reboot edl...but it still dosent help ( thats a working phone and one stuck in edl )
[OnePlus 11] sefai77:
its ok. My phone is working now with coloros. i want to convert oxygenos.

What order did you do the process in ?
[OnePlus 11] sefai77:
I am currently using the 2449 model working with oxygen oss. now i can't switch between coloros and oxygen just like on oneplus 9 pro.
[OnePlus 11] ChrisFeiveel84:
You can Switch to cos when you flash the full cos Update (payload.bin) with fbe (it is better you use on eu model oos eu and on china op11 is it better you ise cos)
[OnePlus 11] danrch0829:
thanks for the suggestion
[OnePlus 11] Jason_Lim:
Is the oneplus 11 china version COS , if using the Malaysia sim card is slower ?

translated from this Chinese forum (Need to install Coolapk's app): https://www.coolapk.com/feed/437324...yMjNmYTM~&shareFrom=com.coolapk.market_13.0.2

download adb tool，fastboot enhance tool，Oxygen a07' OTA full package（we only need payload.bin），Oxygen a07's ofp package（we only need my_preload folder），cos's unbrick package（we only need oplusstanvbk. img)，大侠阿木工具箱 https://optool.daxiaamu.com/wiki_pctool （we only need the driver）。

1： first, use 大侠阿木工具箱 to install driver，connect phone and enter developer mode，open usb debug and enable OEM lock。

execute "adb reboot-bootloader"，to let the phone enter fastboot。

execute "fastboot flashing unlock"，volumn down，power button。

after entering bootloader，execute "adb reboot-bootloader"。

2：extract Oxgyen a07's payload. bin file，open fastboot enhance，ignore unknown partition，show llog and then flash in payload. bin

3：use fastboot enhance to enter fastbootd mode，the phone should enter language selection，make sure✅ignore known partition，then flash the payload.bin from Oxygen a07's package.

4：extract oplusstanvbk.img from Abandon_PHB110_V13_202301030.zip into adb tool's radiofolder。（this is to avoid bootloop）

extract the my_preload folder from the a07's OPF package to adb toolbox folder。（This is the pre-installed software of Oxygen OS）

when in the fastbootd（language selection UI) mode, flash in the following two files,

fastboot flash --slot=all oplusstanvbk radio/oplusstanvbk.img

fastboot flash --slot=all my_preload images

5：We can enter oxygen os now，do not insert SIM and skip all the setups after entering the syaem。

enter developer mode，enable usb debug，execute "adb reboot-fastbootloader" to enter fastboot，execture command "fastboot flashing lock"，press volumn down and power and lock the fastboot。

enter Oxygen OS again and SKIP ALL THE SETUP steps，

MOST IMPORTANT: DO NOT UPGRADE THE SYSTEM USING OTA!!!!! It will bootloop.

From some Chinese forums, I can see some posts saying that the A11 ColorOS had removed the region lock. I am using this version now and there haven't been any region lock messages appearing (Had been using this version for 1 day now).

Hello friend and thanks for your message, you're saying that ota update will bootloop the device, but the site claims that ota will work. I know the way to convert to oxygenos, I just wanted to know if there's a new method that will allow the device to ota update
