Forgot to mention that the reason that popped into my head is because Apple did the same thing with the US and China a few years ago when the iPhone X came out. Physical SIM + ESIM for US and 2 Physical SIMs for China
[OnePlus Nord N10 5G Guides, News, & Discussion] topofthehat:
Ah, i see what you mean, but atlas, that is not the case here.

It wouldn't explain the sim tray in the EU/international version.. Pretty sure the guy in the review is in the UK doing a review of the UK N10 5G. I compared this to my phone sim tray, it is a bit different. Look at yours, the BE2026 and BE2025 sim tray should be the same. You'll see what I mean.

Picture from the EU N10 5G video review:

View attachment 5195601

The website notation is probably because someone in marketing was lazy and copy and pasted the NA specs from the international one. They changed the relevant information for the SIM tray in the main section but forgot to delete the fine print footnotes.
[OnePlus Nord N10 5G Guides, News, & Discussion] topofthehat:
Oh now I get the point you were trying to make. I suppose that is possible. I highly doubt it, since this is suppose to be a budget 5G. Apple and Google were more than happy to advert they were going to have esim on their phones in the future through updates (i.e. Pixel 3a).

We've heard nothing from Oneplus about esims. It would seem odd they would choose to do so starting with one of their budget phones. I could equally be wrong. However, for me, if they went esim + sim, i would still rather have 2 physical sims. (I already have a Pixel 4.) That is part of the reason I wanted (and wrongly assumed) the N10 5G in the first place; for it having 2 physical sims.

The simplier explanation would be that Oneplus is just following the convention of their competitors: NA models gets single sim, International gets dual-sim.

Wait.... So we have three hardware versions in the US? O_o?

BE2025 - Metro

BE2026 - Unlocked from Oneplus directly

BE2028 - T-mobile???

I just upgraded to the latest dcd rom .6 from and older one. I didn't touch vereizon's.

When trying to configure the gps, I set th GPS hardware port to com 4, baud rate 4800 and the program port to none.

After I save and see that google maps cant find th gps hardware, I go back to the win mobile gps hardware settings to see that it switched back to none.

The gps was working fine before I upgraded the rom.

[ROM][11.0] WaveOS 4.1 Rasmalai for Redmi4A/5A [OFFICIAL][ROVA] [ROLEX/RIVA]

----------------------------

WaveOS 4.0 - Rasmalai

WaveOS is an android custom ROM based on AOSP, focused on delivering a perfect blend of aesthetics, functionality and performance out of the box. The version 4.X is based on Android 11. Various optimizations and enhancements have been merged from CAF and upstream AOSP to maximize performance and battery backup, and improve OS functionality. We provide a unique and beautiful user interface out-of-the-box that's inspired by OnePlus' OxygenOS, and can be tweaked to your liking. We've also added handy features and customizations that improves user experience and proves to be useful at the end of the day, rather than bloating the ROM with unwanted features and customizations that could cause stability issues. We hope you like it! #NeverBetter

Hi, I now have this ROM (see attachment). To install WaveOS do I need to update the firmware or do various downgrades, or can I install the ROM directly following the instructions?

Thx
[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] asdrubali:
You've done a great job! I migrated from stock MIUI 10 and I feel the entire system works 10 times faster and better. It seems that everything works properly: radio fm, wifi, 4G, bluetooth, camera photo & video + flashlight, LED indicator, 2DTW, screen rotation, vibration, 3 physical button navigation. Charging and discharging behaves as expected.

At first run I installed all the apps on the internal storage and there was about 3GB of free space left, so I formatted my 16 GB external SD and moved everything to it. Now I have 10GB of free space on my internal memory.

What is working as not expected (WaveOS 4.1):

— Gesture navigation works except the swipe from either the left or right edge to go back (this issue was confirmed by other users on other forums).​

— Some parts of the firmware are still in English i.e not translated (I'm using italian).​

— Scrolling screenshot​

I really hope you will keep to maintain this firmware because the problems found appear to be at the software level.
[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] ashisroybarman:
As mentioned earlier, swipe actions are not working from both sides. Plus did not find any option to turn off hardware nav keys. Kindly resolve these issues in the next update, hope it will come soon.

By the way, as far as I have experienced installing numerous ROMs in Redmi 4A, this ROM is the smoothest, fastest and beautiful one (no offence what so ever). Aesthetics of the ROM developer is good. It also has decent battery backup, so I will stick to it and wait for bug cleanups.

Hi Thago,

I found some problems in version 4.1 rolex:

- the function mentioned in Features "Power off alarm in inbuilt clock app" doesn't work

- system updates don't show in the settings (I can search it but it doesn't show up)

- weird glitches in animations (I don't know how to describe it, some transitions will flash at the end of the animation)

- Enter SIM code screen shows twice (After I entered the PIN, the screen shows again and then disappear)

I'm not an experienced user so probably I just installed it wrong. I had some custom ROMs before, but every time I faced some problems. Even on the stable version, there were crashes and bugs.

Thank you so much for the help.

Edit:

Here is a video to shows the glitch:

The graphics glitch disappeared after I installed the Triton-kernel 4.9 for now.
[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] asdrubali:
this isn't a bug. OTA updates (over-the-air) it's something that should be implemented by the developer. You phone connects to an internet server and checks for updates, but what if the server does not exist? So, there's not reason to keep an option for something that does not work. Hope this feature will developed if WaveOS wishes to be as big as Cdroid etc.
[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] Surdorstomm:
Thank you for the explanation. I thought that an "official" ROM has the OTA updates in default (like some standard). Just my unawareness. I had some "official" ROMs before and each ROM had this feature. I just found it weird that I can find the System updates via the Search Settings function but when I select it, the item isn't there.

you can choose any package but I recomend the basic one, just clean flash, then flash Gapps, reboot and enjoy.
[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] zer0def:
There are a couple of additional steps to make full-disk encryption stable, because ROMs (not just WaveOS) will crash a lot after initial flash:

(optional) if you need to recreate the encryption footer after data partition format/wipe from previous ROM: flash stock (for example, this one)

fastboot flash a recovery (I chose official TWRP 3.2.3, one without F2FS patches)

wipe system, vendor, cache, Dalvik/ART, but DO NOT WIPE/FORMAT DATA, IT WILL WIPE THE ENCRYPTION FOOTER, FORCING YOU TO START OVER

flash ROM

reboot into system, you'll boot directly into the system without first start setup, the system will be crashy - that's expected

go to Settings → Security, encryption status should be "Encrypted", not "Phone not encrypted", set screen lock as you ordinarily would for "Secure Startup" - this will be your decryption credential

reboot into recovery, wipe → advanced wipe → select "data" partition → repair or change filesystem → change filesystem → pick your preferred filesystem (I chose ext4)

DO NOT DIRECTLY WIPE/FORMAT DATA

reboot into system, it might require you to encrypt the phone, but once you do that, it should be working as intended

if you provide different unlocking credentials now, you will have to remember both, one for decryption, the other for screensaver unlock

ROM working very good. Thanks so much to developers.

What I'm missing:

1. Disable hardware buttons when gestures are on (little detail but important for a better experience in my opinion)

2. Fix square icons 5x6 (the dock is 6 icons width but the screen is 5)

3. No synchronization toggle. You have to navigate to settings/accounts to switch it on-off.

Anyway...it's an enormous work...so smooth, impressive performance for the 2gb ram mobile. Amazing.

@Thago I just randomly fixed back gestures by adding qemu.hw.mainkeys=0 to /vendor/build.prop (anyway the HW keys are still active)

This is a obvious bug. Try to implement this to the source code.
