Weak Signal Strength on Chinese OnePlus 5t flashed to Oxygen OS - OnePlus 5T Questions & Answers

I get weak signals & bad LTE reception in my home country. My phone is rooted and is on Oxygen OS. Is there a modem/firmware that I might flash to make the radio the international version. Thanks

Same version,but not meet that problem yet. Maybe try clean full package rec clean and reinstall the os

OnePlus 3 A3000 model!

I've never previously owned a OnePlus device, so i don't know how to tinker with it.
I'm Coming from a Nexus 6p. I've ordered a OnePlus 3. But it's the A3000 model which has the Hydrogen OS installed.
I like the Stock Oxygen OS of the OnePlus 3. My question is,
1 - Will things i.e; rooting methods, rom compatibility, etc be different for A3000 & A3003.
2- Will i be able to flash and receive OTA updates of Oxygen OS on A3003 Chinese Version.

1) they are the same. Just different regions with different lte bands. So flashin roms are the same.
2) once you install oxygen Os you will recieve Ota as normal.
My opinion: i like more the hydrogen os than oxygen. Its more battery friendly and it feels like device performing faster. So i would pike to stay at h2os. Just debloat it

When installing firmware is necessary?

I see some people recommending each other installing firmware packages (3.5.5 in most cases) and I just wonder what's the point of this? I've installed official snapshot of CM13 right after unboxing of my OP3 and now I'm confused - did I make it right? Maybe I should first update OxygenOS and THEN install CM13? Or maybe I should flash 3.5.5 firmware zip over the CyanogenMod right now?
Thanks for explain in advance.

You don't have to update OxygenOS before CM, so you did it right! (But at least in some versions of CM14.1 it is required to have OxygenOS 3.2.6 or newer to work.)
3.5.5 is just a community build based on OxygenOS.

Interesting! I did flash MC13 without even knowing that i needed 3.2.6 lol it worked just fine and i have flashed MC14.1 a few times... Once you got MC13 installed going back to stock really really sucks!!!

Signal Issue

Hi, I just bought an Redmi Note 5 Pro 6/64 on AliExpress, and it came with an unlocked bootloader and what it seemed to the a global ROM of MIUI. I didn't update because of ARB, since I read that it could brick my device, and it was ARB 3 so I didn't wanted to flash anything official. So I installed TWRP and flashed custom ROMs, but it seems that on every ROM I install I get no signal detected, I have to manually toggle a lot the network toggles to MAYBE get my Redmi Note 5 Pro to pickup signal. I'm just wondering if anyone has gone through this and how did you fixed it? I don't really want to flash the official global ROM to get it fixed properly. Thanks.

What version of MIUI are you on? You can check the version and flash the firmware only for that version. That should, in theory, fix any signal issue you got.

Right now I'm on Masik X 1.0, but it also happens in every aosp based ROM.

yes, because firmware isn't rom dependant. Like i've said, check if you're on ARB4 or 3 and flash a firmware depending on the result (be very careful).

SIM Card Swap after downgrade from Pie

Hello
First I'd like to apologize if I made thread at the wrong place
A few days ago I tried some custom ROM base on Pie like RR , Arrow, Liquid Remix, MIUI.eu, etc. (I can't remember exactly all of them.)
And then I went back to Oreo stock ROM. But so weird the SIM card now swap from original. (SIM 1 become SIM 2 & SIM 2 become SIM 1.)
I already tried many ways but still no luck until now. (Flash Pie again & downgrade to oreo.)
This also happened to my Mi A2 Lite before & already solved by replace modem.img file in Oreo with same file from Pie when flashing.
Unfortunatelly the method from Mi A2 Lite can't be applied here cause sakura doesn't have modem.img file.
Would be very appreciate If anyone know how to solve this & willing to share here.
Thanks a lot

You have flashed Pie version eu.
That problem wont happen with AOSP based roms like RR, LOS, Viper etc.
Many people lost their VoLTE also. As of now there is no solution(As far as i know). You have to stick with Pie build itself. If you fixed it, let us know.

Even if I flash back again to Pie (MIUI.eu, RR, LOS, also Mi-globe, etc) the problem still exist.
I have tried with other SIM card as well. But nothing fix.
So I guess must wait for next update to get fix. Thanks for the answer.

I'll still stick with android oreo 8.1 till now. If I flash miui android pie 9.0 (maybe u mean android 9 ? ) , I will activate ARB which I avoid it. So I can keep the getvar anti version null.
I already tried to flash the latest firmware from yshalsager but nothing has change. The problem is still exist.
You can try & let me know the result. Good luck.

Nope, don't flash miui9.
Instead,there is a file named "daisy_modemfix" in mi a2 lite forum.. flashing that via twrp fixed that problem ?

OOS 12 OB 2

Strange, it seems to me that this forum has completely died. Considering that Oneplus 7t is already an old device, I can understand that. But no one, absolutely no one comments on the new update that came out, OOS 12 as OB1 and very soon after OB2. Bearing in mind that Beta 1 and 2 were released for the Indian version and not for Global or EU... Does anyone have any experience and what are their first impressions? Can it be used as a daily driver on this device? Does Magisk Roor work? OOD? Did you so complete whipped all data before flashing? Can you install it over Ob5 (officially it suggested to flash it over latest stable version)? Did anyone install it on EU or Global variant 7t (again, officially ther is significant difference on Android 12, between India and Global/Eu variant)?

Ob2 fixed dead fastboot mode on ob1. Works great for eu or global OP7T. Very stable and perfect for DD. Keeps data if "local update" (download file via oxygen updater app). Rooting via magisk-patching boot.Img and then "fastboot flash boot magiskpatchedboot.Img" works fine. This "IN" version does not have IN bloat and meant for all op7t. After update booted up fine then do it again to install ob2 into slot B.

Thanks for these details. Does this mean that it is safe and that without data loss it can be flas directly from OB5 (Global) ?
How is battery? Speed? Benefits and cons, compare to OB5 oos11 ?
Your, subjective filing?
Thanks in advance

Yes on updating with data preserved. Battery is better than oos11. Faster and smoother than oos11.

Thank You... And one more last question... On Ob5 we had AOD (exist in op lab).. But it's was not present on stable version OOS 11... Does AOD wotk out of box on 12... or you can turn it on if you are Root like it was possible on oos11 ?

No as you'll lose root with local update and twrp won't work on oos12. I patched mine and fastboot flash boot magiskboot.img

I'm curious. What do you guys still need root for? My phones were always rooted since my Nexus S until Nexus 5, but on my 7T I don't find it necessary anymore.

I need it to have full control over my device... to get no Ads to use of Titanium Backup, to be able to control device thrue Tasker (Wifi, mobile data and more..
that I use), it's must for me
And I apologize for being boring, but just to confirm one more time... There is no difference between the Indian version and the EU/International version in terms of modems and frequencies for 3g/4g connection? Or so ever, to be obstacle to use it as main driver in Europe or World wide?
I am on OB5 International but I live in Europe.

My device is global and I live in Southeast Asia region. Signal surprisingly improved using OB2 indian rom. But I can't say the same thing for other locations.
Anyone use it Europe?
