[OnePlus 8 Questions & Answers] thvardhan:
Hi, I've got my OP8 when android 10 was around. I remember having widevine L1 back then and playing HD content. sometime later, 1+ launched A11 update and doing so broke my widevine to L3. As I read many posts online it seemed like a common occurrence. People were talking about how they got it back to L1 after a few updates or somehow by resetting cache and stuff. Right now I am on oos 12 and I still have not got any update to fix it, even worse is, I've tried literally every method I could find online but none of them worked. I've even tried MSM my way back to A10 (which also showed L3). As my last resort I contacted 1+ support who said they will provide me some special "update" to fix the widevine but its been weeks its nowhere to be seen. This thing is very annoying, buying expensive flagships just so they can go to waste over trivial stuff, the screen is very good but if it cant play HD content then whats the point. Never buying any 1+ device again.

I am asking the community to let me know if I am missing something, anything that could help me bring back my widevine to L1. I've not installed root or custom os. locked BL. very weird that no matter what I do my widevine is just dead. I would really appreciate if someone had similar issue and was able to fix the widevine.

Hi,

After struggling hard to find how to update my unit (what doesn't seems possible with USB key in my case ; only with a MicroSD card), I finaly did it.

This new system is Android 11 based, and allow to connect to Android Auto wireless, sounds good uh?

My unit is AC8257 based, and has 8 core, 64 GB ROM, 4 GB LPDDR4 RAM @ 1024x600, but the upload also contains 800x600 & 1280x720px, there is .BAT files that make easyier to pick up the good Android_scatter file.

Here is where I come from first :

And here is where I am now :

Below, a picture of the app/system that detect that my phone is close by and ready to pair with Android Auto. I first had to connect it with wire to show him the way. It now seems automatic.

[Android Head-Units] AML276:
Do you know if this fixes the issue on the factory Android 10 firmware with the accessibility services being deactivated even though I've disabled the apps from battery optimisation?
[Android Head-Units] noiwid:
Hi,

the accessibility menu is available, but how to ensure the service is running?
[Android Head-Units] AML276:
It's the downloaded services that show up under the accessibility menu from other apps like for AppMgr III, macrodroid, bitdefender and most reboot apps. On my unit that came with Android 10, these services get automatically disabled by some task manager or something.
[Android Head-Units] noiwid:
The killing app system you mention might be DuraSpeed, that's supposed to free up RAM. When my unit was Android 10 based, I had a menu to disable it, not sure it's still the case, gonna check Asap.
[Android Head-Units] AML276:
Oh is that what Duraspeed is. I thought there must be some other/extra task manager killing it off but I was only looking at other apps that might be doing it. I'll look at disabling it. Do you think the android 11 firmware is better, do you like it more than 10?
[Android Head-Units] AML276:
Was Google maps slow to open or to start navigation after you enter an address on your old firmware or is it faster on 11?
[Android Head-Units] noiwid:
I think the Os is better, for few reasons:

- a bit faster on startup, I set it up to auto launch Waze when it boot, whats seems to be done easyly.

- better UX, you can choose between 4 layouts for the launcher, and one of them offer the possibility to personnalize 4 or 5 apps shortcus from main screen, what I found really usefull in daily use.

- Android Auto that can work wirelesq, even if I now realize Android Auto is useless when you have an Android unit.. you can do more straight from the unit (if connected online) than thru limited features offered by Androïd Auto.

about Maps delay, hard to say as I mainly use Waze, i don't have enough track records with G Maps on this unit, that I only receive 1 or 2 weeks ago...

I'll add a few screenshots of the launcher, do you want to see particular screens/menu?
[Android Head-Units] AML276:
I think I might know of the 4 launchers. From an xyauto bundle?? Hopefully which is this one as it's the only one I've found that's even close to the type of layout I need and I was going to try and force load it in the morning on the current firmware.
[Android Head-Units] AML276:
I wonder who made the original firmware you had that listed the hardware as ac8257, but now you have the bosion b200 firmware I think with android 11, as my factory Android 10 firmware is the b200 already.
[Android Head-Units] AML276:
How did you go checking if Duraspeed is still part of the android 11 firmware? Do you have any downloaded services under accessibility and do they stay enabled?

I disabled it and the downloaded services stay enabled after a reboot now but something still turns them off once the system has been running/idle for a while.
[Android Head-Units] AML276:
What do you have to do once you've downloaded the firmware. Do you run some bat files on the PC first?
[Android Head-Units] AML276:
The file doesn't have all the scatter files for the other bat files. Looks like you saved/uploaded just what was created after you ran the 1024x600 bat file.
[Android Head-Units] noiwid:
hi,

oh. it seems this package is already set for 1024px (vendor did it) but it's easy to adjust

what's your resolution?
[Android Head-Units] AML276:
Thanks, I managed to work it out and unfortunately this new firmware hasn't fixed/changed my issue with the downloaded services being disabled. But has now added an issue of the hotspot enabling rather than wifi after every reboot even though I've disabled carplay (which seems to be what triggers it)
[Android Head-Units] noiwid:
hi,

i manage to disable this autowifi turn off/ tethering turn on.

on my side it was caused by Android Auto that detected my phone nearby (phone already associated thru wire), i turned off wireless settings on Android Auto on my phone (s20) and it stop turning off my wifi on every reboot.

about the launcher 4 display, are they same than on your prev system?
[Android Head-Units] AML276:
No, I just had the 1 'ugly' UI on the factory firmware. Not using Android auto on my phone (but I'll double check for any related settings) and I don't even think I've paired it via Bluetooth since the upgrade.
[Android Head-Units] noiwid:
it seems this system (or unit?) don't allow to enable both wifi & wifi hotspot.

in wifi, advanced settings you can try to enable auto connection to wifi.

what I did on my side is paired my phone with bluetooth, and add a script on my phone with Bixby Routines to tell the phone to enable the wifi hotspit when he's connected to the car with bluetooth. As this way when I get in, bluetooth connection is automaticly done, the phone auto turn on hotspot, and car unit auto connect to it... when I disconnect bluetooth, it stops hotspot automaticly too...

[Android Head-Units] AML276:
I'm not sure how that happens. Did you have all 71 files saved to your USB drive as I initially had some trouble with the upgrade as my PC didn't copy all the files over. Maybe you can just do the upgrade a second time incase it missed a file. I've also read that some of these ac8257 units have fake images, mainly that it says android 10 but it's really 9. Probably needed to use aida64 first to check the hardware but what does the aida64 app say you have for ram?
[Android Head-Units] AML276:
So I have a new issue to add to my list. I've installed the gboard keyboard app and enabled it as my input method, but after a while (probably around the same time and same cause as the accessibility services being disabled) the system will revert back to the aosp keyboard.

Anybody got any suggestions?
[Android Head-Units] dj.shauny.g:
Would it be possible to the latest firmware via usb option?
[Android Head-Units] vz_commo:
wasnt for me that why i had to use the spflash tool option

Hi have you tried 360 camera app. I have 4 cameras fitted but the app says not activated. Any clue
[Android Head-Units] vz_commo:
Sorry man I don't have said app or 360 camera, I'd suggest trying another firmware and see how that goes
[Android Head-Units] rkn8677:
Hello guys I reverted back to the firmware for which I posted the link before. Fastboot working perfect with google maps and other apps. Bluetootj connects very quickly. 360 camera app working good its bit different than other AVM360 but not asking for activation. For wireless android auto I purchased headunit reloaded emulator app from play store for $6.99. Set it up with wifi launcher app in my phone. Works excelently faster than Qlink app. So any one wants everything working give a try. cheers.

So I've just paid to have the reverse camera that came with my unit installed, which I should have been able to do myself, and neither of us could get the image to show. Just a blank screen with the reverse guidelines. YouTube videos etc seem to indicate that it's just a case of switching the rear camera type to AHD_720 and do a reboot, but that's made no difference.

And What's the precamera input type setting all about

Anybody got any suggestions please?

[Android Head-Units] rkn8677:
Hi Most of the reverse cameras that come with the head unit for free are NTSC output type. So when you go to settings then select camera hardware channel or similar option to NTSC or in some units its CVBS kind of. Try it good luck
[Android Head-Units] rkn8677:
UI selection is in GENERAL options (last one.)

Hi, confusion for me. too many version publish here. I think i have same situation, 360 camera. I not really want broke my device ;) what is version you use for 360 camera and no choice to use upload with male male usb + software ? i can't upgrade with usb storage key right ? Thank you
[Android Head-Units] AML276:
Thanks. I believe I tried all settings, including cvbs pal and NTSC and also ahd 720 pal and NTSC.

I think I ended up receiving a CMOS camera as that seems to be what the seller was also selling separately. Luckily I eventually found a spare AHD camera and swapped it out.

i can't do this procedure because SP flash tool say MT8127 scatter file model mismatch whit Ac8257. Someone have scatter file i can use to make full backup of my device ? what is wong, this procedure is too old and this method not work for AC8257 device ? thank you for you help
[Android Head-Units] wanted99:
ok i have found this scatter file i can load in flashtool whitout error to create backup. i dont know if everyting is ok on backup file. i use this method to know size of partition.

okkkk. is a different version of 2610pro.... is not the same

i think your version is

maybe i will try to load this version . So confusing. lol

on other post you can found 2610pro+ and 2610pro. is not the same. date is 20220613 on this link and not 20220614
[Android Head-Units] vz_commo:
From memory I had to use sp flash tool version 5.2152 otherwise the scatter file would give errors
[Android Head-Units] wanted99:
ok, i have this error because bad ascii on folder name.... Need remove all bad ASCII . haha and is already posted before.. damn.

Ok i resume for other.

-Use recent SPFlash tool like 5.2152

-Remove all bad ASCII folder name. i suggested use short path like c:\ROMS\myrom\simplefoldername because you will get error on spflash tool.

-for me i use android_config_Slim xml config because i not have 1Din enclosure

-Create a full backup of your device with spflashtool, You can use youtube video i post before if you cant use "memory test" to know where partiton begin and stop. Use WwR_2.50_Eng to check partiton structure and cut your userdata. if you can read system.img ext4 partiton i this is not bad. You can keep your RAW data because im really not expert for backup data with spflash and WwR_2.50. Maybe someone can give more detail because i not have "test RAM" option when i use spflash....

-Watch out 2610pro+ and 2610pro is not the same. I think 2610pro+ have slow boot problem. Need confirm this.

-Maybe use format + download can solve slow boot problem but i think is cause by 2610pro+ version or flash method (spflash tool vs USB dongle update.

-Maybe some person will have problem with 360 camera for activate software license. Need confirm this and found solution. i think other apk can solve this problem.

-When firmware is install you need PC mouse to solve, touchscreen calibration, bouton setup, radio setting, language, etc.

thank you for you help. too bad i cant test 360 camera because i not have right now but i want buy kit in the future. Sorry for my bad english. lol. If everyting work good for me. i think i will check to extract and recompile system.img and rename \system\media\bootanimation* file because is really ugly Target brand animation ;) and add some apk in the firmware. If someone know where is UI file structure maybe i can add other with apk MOD with other color. Normaly is not really complicated edit image in apk et sign apk after. Someone have root solution too ? just more easy to do some test for MOD this firmware....
[Android Head-Units] rkn8677:
Hi Can you please let us know how to extract and recompile system img file. That will help to put 360 apk which does not ask for activation and then everything along with wireless android auto will be working. Thanks
[Android Head-Units] wanted99:
i think you can use ImgExtractor https://xdaforums.com/t/guide-how-to-extract-system-files-from-stock-firmware.2667610/

warning: i not already tested

i have boot.img rooted too. i will try this tonight before share file.

i will add some apk extracted from other firmware. not tested too.

Oh, i think i not have slow boot problem finaly. long boot only after 2 day. Everyting look normal.

i see you cant connect OBD2 in gui interface but when i configure obd2 bluetooth direct in the software. OBD2 work good. idk why
[Android Head-Units] wanted99:
Finaly i cant root because boot.img is too small... i have boot.img working with root but in not the good model and many problem after flash this. When i try with magisk i have boot.img little bit too huge. i cant flash this with spflash tool. Cuz of this i will not try to load whit adb command and probably cause brick on my device. Other solution is load this from recovery partition or resize all partition to get more huge boot partition....

i can but i not want risk my device. Sorry... the most small boot.img rooted i can have now is 10347 kb with magisk majesty for android 11. max size is 10 240 kb for this partition structure. Maybe someone will want change scatter file partition size and calculate offset to get space from other partition and do full format... but not me. lol

maybe i can broke your device for you..... looooooooool ;) a volunteer ?

i will add magisk majesty apk at this post
[Android Head-Units] wanted99:
WARNING - NOT USE THIS FILE - IS A TEST for 2600pro+ firmware​

I am not responsible for damage. at your risk. never test.​

ok, omg, is done :) i have change hex value in scatter file to

- resize boot.img partition (SYS27) little bit more huge.

- move next (SYS28)

- move and reduce next (SYS29) tee.img - space not use in this partition

I don't have the courage to test it ! hahaha

If someone want check the job, thank you...

in theory, it can't break the device because the bootloader is before...

*** YOU NEED CHECK "format + download" and select all partition. Because partition change size ****

-try without replace boot.img, keep all original file, just replace scatter file

-only for 2600pro+ file firmware

-flash just whit the new scatter file (normaly everyting will work same to original 2600pro+)

if not work - reflash with 2600pro+ original scatter file (format + download)

if work. replace boot.img by my boot.img rooted. and flash only boot partition. ( i already tested with a bad boot partition and not problem to reflash after)

After you will be rooted with magisk :) ( i think )

Do not use if you not really need root. is only for person need help to MOD this firmware and developer. Dont take this risk to use format cuz is really dangerous.... Rememder, if you change firmware again you need do full format to restore partition structure. for now is the same version. just new partition structure + rooted. If you test this come back to me if work or not. If someone can root boot.img with file smaller of 10 240 kb from original boot.img. Cool ! Send to me please. me, I did not succeed...

I'm going to think, if i test or not. My GF will kill me if i broke her Android Radio... looooooool

just some precision for AP turn on and wifi disable automaticly is normal. When your phone make Bluetooth connection.
