Hi.
Is there any way I can change the firmware/software of my h910 V20 to H915, US996, F800 or other non-carrier-branded stock firmware?
Pls recommend a good guide if you know one.
If yes, can I still update the phone to newer versions of the firmware I switch to (eg future Oreo releases for the firmware/device version I converted into), or would I have to flash something in between?
Please advise, I'm relatively new to this.
Thanks in advance.

this guy says he can downgrade ls997 to zvc to unlock and root.

Can you guys check and tell me if this is real? is there a way to root ls997 oreo now that I do not know?
kindly let me know.
thanks in advance.
Looks like that's just for SIM unlocking the phone. The LS997 is known to carrier re-lock itself when upgrading to Oreo. Software version ZVC is still ARB1, so it's still unrootable as far as I'm aware.
Widevine is currently L3, but I need it L1.
Oneplus 8 Pro IN2020, 11.0.4.4.IN11BA
Radioactive kernel 2.1.4
Magisk 22.0, manager is already hidden, reboot done. Widevine is still L3.
What am I missing?
Maybe something in this recent thread:

Thanks man. I did a little read-up on the issue and it looks like a mess. There is basically no straightforward way to fix the DRM level. I've tried deleting data/cache, reinstalling Netflix, whatever possible solutions I found and they didn't work.
That method with rolling back to Android 10 could possibly work, but I'm not going that route. It's too much to do to fix a little issue, and even then it's not guaranteed to work.
It may be easier than you think. I'm on an Op8T 5G but the devices are similar. Install HideProps in Magisk https://forum.xda-developers.com/t/...safetynet-prop-edits-and-more-v5-4-0.3789228/ then from a terminal emulator (like Termux) type (separate lines are semicolons: su; props; then go through the list of approved uploaded fingerprints and select an EU one for your same device. Then reboot. Worked on my Op8T when my Widevine dropped to L3 after a BL unlock. Right back to L1 after. Good luck!
Use Magisk Hide Props config direct link here install in Magisk: https://forum.xda-developers.com/attachments/magiskhidepropsconf-v5-4-0-zip.5189681/

I've had a fingerprint installed for EU firmware, but it still doesn't help. I pass SafetyNet, but Widevine is always L3. I'm starting to think this has something to do with the fact that I flashed EU firmware onto Chinese (IN2020) phone, in order to get faster updates, than for International firmware. Anyways, I think I can live without Netflix
Hi Everyone -- I have had a OP8 Pro rooted for a long time on L1, and just noticed it got changed to Widevine CDM System ID 8159 and L3 with the latest OTA updated. I am familiar with props config and tried switching to EU firmware all to no avail -- nothing changes.
Since the OP8 Pro are so cheap now, I bought a new one and will just use the MSM tool to flash this back to it's original state, and give it to the wife / sell it etc.
The magic question is this -- OnePlus said this only happened with some devices -- so if I unlock and root the new one is it going to go to L3, or does no-one have any idea?
BTW -- I contacted support and they said I could either send it in now for a flash, or wait for an update that will fix the issue?
No-one seems to know what the root cause is.
Also, I guess a new update is coming out any day for IN2025...? Maybe that will fix it?
Thanks for any info
MW.
I should say that the latest update (11.0.5.5) has changed Widevine to L1. OnePlus fixed it without my intervention!

I booted into EDL mode and flashed 11.0.4.4 EU firmware via MSM tool. This essentially overwrites any previous software on your phone.
After flashing, you need to unlock bootloader again via developer settings. And also update to 11.0.7.7 via OTA. Most likely, the DRM-level will be fixed after all these manipulations.

also did you open bootloader right after 4.4 or update it via ota, and then unlock?
