Cant Rollback - Cant Update on 8T EU (Solved) - OnePlus 8T Questions & Answers

Hello.
First of all thanks a lot for the instructions all around!
I ve KB2003 (no root) and i made the update of kb2003.11.C20 some months ago. Since then no more updates.
I am trying just to rollback and every time system update failed pops. I have already read everything on forums like https://forum.xda-developers.com/t/oneplus-8t-rom-ota-oxygen-os-repo-of-oxygen-os-builds.4193183/or from https://community.oneplus.com/thread/1555060
I ve tried also to change oplus_update_engine_verify_disable=1. Still the same error. i have also try many roms for 8t EU.
I have already backup my files so i dont care if loose anything.
Any advises? I think that my last hope is via Pc flashing.
Thanks.

I think using restore stock OOS11 using MSM tool is better than rolling back.

Hello Rootk1t!
do you have any available link / source how to do it ?
Thank you.

Firstly, do not PM me for any questions !
Ask in the forum here. You may mention me and I will get back to you !
About your query, the firmware you mentioned has only camera quality issues ! There aren't any bugs to my knowledge !
If any user thinks there is something to add/ remove, kindly do correct me!
About how to roll back, you will need flashtool and FTF file of xperia to flash your phone with older version/ newer depending on your choice!
The details are available in general section !
If you are still confused, quote me back !

Can you elaborate!What exactly are you doing and how are you doing?
My guess is you are using OTA for updates!
Use PC companion to update to the .14 version! OTA failed for me too
Good luck
bicked phone
I just rooted my phone and I looked at some comments about people bricking their phones. I know what a bricked phone is, but I don't know why it cant be fixed. If it's a software error, shouldn't people with experience in that field be able to fix that easy? I'm just curious.

Well, I have been using Sony Xperia since 2011 and I have been flashing ROMs, modding, experimenting a lot with them, I never have managed to hard brick any of my phone !
It is always recoverable ! These users might be new to it !
It is only care to be taken to flash kernels,ROMs,mods which are meant for your device model only! Failure to take caution in this regard might result in hard brick!
Good luck.

Losing mobile data connection on COS13 (opo)

I have installed cos13 over cos12 with twrp and everything works fine except that once a day i lose mobile data connection (network is ok, just no LTE/H/G/E). This happens mostly when i go away from a wifi place and when it loses the wifi connection it doesn't go on mobile data.
Only thing that works is rebooting the phone. i did cache and data wipe true twrp
thnx
Same issue here. Can't find much about this online, as if not many are facing this problem.
I'm on Proximus (Belgium). Double-checked the APN settings, all looks ok.
I flashed another baseband and the problem is gone. (Ook proximus)

I haven't got a custom recovery. Can I flash it using cyanogen recovery? If not I will do it when I have a little more spare time
I don't think so but you can try.
Tried with cyanogen recovery, doesn't work
After months and months of pulling my hair out, daily reboots and trying numerous other suggestions and solutions, finally I've come across this post. It DOES solve the problem with inability to get data connection when leaving a wifi zone. You need to install TWRP first. I can't post the link due to XDA forum limitation for new users, but a quick search on google should send you in the right direction. Thanks diederikmo!
Hey, I've got exactly the same problem, but unfortunately the baseband you uploaded is no longer available. Can somebody please re-upload it? This problem is really making my phone useless.
This link won't work. Please pass a new link.
Please give new link

the downloadlink doesn't work anymore.
Please provide a backup link or the correct name/number so we can search further.

No proof of this! How to be sure that you are not a scammer?
---------- Post added at 09:43 AM ---------- Previous post was at 09:03 AM ----------
OK @wrundawan I found the scam, you have a dead device and you never solved your problem. You only need an other device to play with it and try to repair YOUR device, that's why you can't prove anything. I searched for your old posts on Xda and I confirm that your phone is always dead and I found this from you on the web who comfirm this again: https://forum.hovatek.com/thread-16341.html
Other thing, selling services and spamming all threads is against forum rules so I will contact forum moderator to have his opinion.
To all users, I will make a small guide to explain how to unbrick your phone, it works in some case but not 100%. For the short story I bricked my phone some weeks ago with the same result, only red light, and I successfully resurrected it. Don't worry it's free, you can do it yourself and I can provide a video for proof
Buddy check the date of that post at which I had posted it.
Currently I had fixed my device and also helped other guys to fix their phone.
I hope your just eagerly waiting for posting me here solution as till now you didn't got any solution. As I said my solution is paid, I am not rich enough to do it for free.
Show me single person with whom I did scam.
Good to know if you got solution and posting video soon.

French language

Hello
What official (ota8) rom oreo has the french language choice inside système please ?
I would like on BLN21C432B382 upgrade to OTA8 (French inside) and later Pie (French inside).
Thanks for your help.
Regards
Both Indian and Chinese version of EMUI 8 should contain french by default, anyway I used Indian build and french was there, so: go here https://pro-teammt.ru/online-firmware-database-ru/?firmware_model=BLN-L22HNC675&firmware_page=0 and download the build BLN-L22HNC675CUSTC675D1B510 (8.0.0.510) dated 2018.07.19.
Then you can proceed going to Pie unofficially (no official build for Pie on Honor 6X - the device shipped with Marshmallow, has been updated to Nougat and received Oreo only in India and China regions (miraculously, since that there were already other new phones by Huawei).
No regrets leaving EMUI anyway
Hello

Oh sure, i have understood now
Yeah you have to debrand to BLN-L22C675, but it's a thing that HwOTA can handle. You just have to choose "debrand" when you see the appropriate option while using HwOTA and the thing will be automatically done during the process. I had your same variant before (BLN-L21C432B3XX, European) and everything went well, just pay attention to the steps in the guide. Good luck :good:
Many thanks RedSkull23
On this thread : https://forum.xda-developers.com/showpost.php?p=79702129&postcount=158,
You said you've HwOTA_BLN.zip file. I'm interesting by this. Is it possible to send me this file?
Thanks
Everything is functional with this rom? NFC, fingerprint, other....
You're welcome boubaka here we use to say thanks with the appropriate button
Of course that I can, now I'm out and I still have to go home from work, but I'll send ya the zip ASAP (I have it on my external hard drive). See you later!

Yes it works, keep it with you because if I remember correctly HwOTA will ask it to you again during the process, in way to re-unlock the bootloader after terminating to debrand :good:
Hi
Successfully flahed !
It's works fine !
Many thank's:good:
[EDIT]
Erf !! :crying: No NFC detected...... No option.....
nobody knows about this rom : BLN-L22HNC675CUSTC675D1B510 (8.0.0.510) ?
Before under BLN-L21C432B365 it's worked fine ...
(I'm Damned!!!) :silly:
Hi, you're welcome!
That is because India variant isn't supposed to have NFC chip in its hardware, so this is the only irrecoverable thing if you come from European variant that have it instead. Yeah the option isn't there because it just shouldn't be there.
Hi
Erghh ! :crying: I'm stuck in 1/2 brick...There seems to be a problem of partiton when I try to return MUI7 by method :https://www.youtube.com/watch?v=_3vqb8hPZIQ
I just have access on fastboot mode and recovery.
when i try to flash by fastboot the message is partiton not the same size.
And by recovery wipe data/factory reset "failed" (logic) .
And by forced install stuck at 5% (logic)
At this point how can i do rewrite correct partition?
Thanks by advance
[EDIT]
I finally managed to return to BLN-21C432B151.
After many tests (HuaweiUpdateExtractor partiton write errors.) and other...
For that, I flashed system.img by fastboot method and the phone restarts to MUI 2.0.
After i update by forced methode by dload whith original firmware
then update by wifi select menu update. :good:
NFC function works fine :good:
Cheers ! :highfive:
