Sorry i didn't understand. ARM 64 or not?

The pico version is ok?
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] dimenfer:
Come on man, ARM 64 8.1, Pico or Nano, any of those two, read the differences on the opengaaps and chose.
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] majark:
WOW, you're so helpful. -_-

However my main question was if i need to use ARM or the ARM 64.

For the second question i asked because sometimes developer suggest which install.
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] bangalimahbub:
Nano
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] dimenfer:
As I said ARM64 8.1, Nano or Pico, the choose is yours, just check which one serves you better, Pico is bare basically, Nano comes with Google App already installed, I use Pico. There's no need to be problematic on the matter, I gave you all the answers but you don't get it, sorry.
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] majark:

Sh*t, what your rom using now ?

Why you post on more than 1 thread, post on your rom thread used now and give a log.

Report without log will be ignored by developers.

But don't send log if you installed a mod like xposed or etc.

Try clean flash.

USB to computer problem

Dear Dev.,

The battery backup is not satisfying, i left it on 50% at 11PM yesterday and at 6AM it was 40% and somehow at 7:30AM it drained to 10% in idle state. I checked the battery status in settings there were huge gap between 6AM and 7:30AM slot.

I'am facing strange issue while connecting device to computer via usb connector. The connection looses and get established second to second and this doesn't stops until i pull out the usb. I tried flashing Fv32 but the problem retains, same with Fv27.

Please give any solution....................

Big problems.

Installed RR-O-v6.0.0-20180424-santoni.zip and it got stuck at the startup animation. After a forced reboot, it started OK, but didn't detect the fingerprint scanner. I tried reinstalling, but it did not help. Of course, wiped data, storage, caches...

So I thought I'd instal the earlier version, RR-O-v6.0.0-20180329-santoni-Official.zip - but I got stuck on loading screen again and it won't even let me enter TWRP. I'll find a way through fastboot, but I need help with installing RR properly... I used 5.8.5 (?) before and it never had any problems like this.

[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] MrGiovanni:
I definitely need help:

I just unlocked my bootloader, I flashed the Oreo TWRP you guys linked and then wiped almost everything (System included), I then tried to install the ROM but it gave me Error: 7.

I read an article which said I had to edit a file in the ROM, which I did edit, and the installation succeeded.

I also tried to install Gapps but it kept saying I had to use the ARM version and not the ARM64 (which is weird, considering the Redmi 4x is ARM64) but not even the ARM actually worked.

I restarted and it just stood there, with the MI logo and the "unlocked" text below, nothing is working!!!

Help please

Edit: I now installed the Xiaomi EU ROM and it works but I really wanted to try this one
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] :
Your firmware maybe too old..
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] MrGiovanni:
What do you suggest me to do? Should I install another firmware beforehand? if yes, which one?

I was on Global Stable v9.5.5.0 - should I install the Developer one?
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] :
Flash this with TWRP Oreo, reboot to recovery (not reboot to system) and reflash rom and gapps again..

https://www.androidfilehost.com/?fid=962187416754476682 -- firmware V035
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] MrGiovanni:
Still stuck at the MI logo.

I don't get it, the Xiaomi EU ROM didn't have any problem.

What I did was:

Opened TWRP Oreo (which was already installed) -> Flashed the firmware -> Wiped Data ofc -> Rebooted to recovery -> Installed ROM (the file I edited, because the other one still gives me Errror 7) -> tried to install gapps but it keeps saying I have to install ARM and not ARM64 (arm doesn't work either).

What am I doing wrong here?
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] :
TWRP : https://sourceforge.net/projects/teamghost/files/santoni_twrp/twrp_santoni_oreo.img/download

Flash this TWRP (flash image from current TWRP)

Reboot to (new) TWRP

Flash the V035 firmware

Reboot to TWRP

Format all (system, data,cache,cust,etc.) except the sd cards.

Reboot to TWRP

FLash Rom and Gapps.. (Gapps must be ARM64 8.1 Pico)
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] MrGiovanni:
Error 7, it's like it doesn't see my phone as a Redmi 4x.

I'm honestly giving up - is this ROM worth all this trouble?
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] :

What is the error message exactly, can u upload a screenshot.?
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] MrGiovanni:
I mean, it's 349 MB, it's not as heavy as other ROMs but I think it's okay? I just downloaded it from the link, nothing else.

Again, every other ROM works so I don't get why this shouldn't
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] :
Ohhh, download this, size 543,9 MB.. Bye, i must sleep..

Another problem I've encountered: why can't I silence my phone? Like, even when I turn down all the notifications/ring volume, it still vibrates for every notification and it's kind of annoying
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] :
In several places you can disable the vibration in the menu, or there is still 'do not disturb' options as well.. ( But as a last resort, use a custom kernel to completely block the vibration. Atomic bomb solution :)

Stuck in installation

Please tell me what I do wrong. I currently have RR 7.1.2, the one of the following link:

https://xdaforums.com/xiaomi-redmi-4x/development/unofficial-resurrection-remix-5-8-3-t3649432

I also have TWRP 3.2.1. Well, when I try to install this ROM (without GApps) there's no problem. I wipe data, system and cache and then flash the ROM and everything is perfect. However, when I try to install ROM+GApps the installation get stuck in the "bubbles" (I don't know how to call it) and it never finishes. I've tried with many GApss (nano, micro, pico...) I'm desperate, I've tried a million times, please help
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] :
Try to older firmware and/or older TWRP (v. 3.1.1 recommended), that rom is only Nougat.. Gapps pico will be ok, but maybe must be find an older version on opengapps.org..
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] IDakota:
And how can I change the firmware? I know how to change take TWRP back to 3.1.1 but I've got no idea about the firmware
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] :
Install this firmware zip from TWRP.

Then reboot to TWRP

Format all (except sd-cards and OTG)

Install rom, wipe caches, install gapps, wipe caches, then reboot..

(Why dont want to use the RR Oreo.?)
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] IDakota:
I actually want the RR Oreo but I'm having these problems to install it. Thank you very much
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] :
Same method, but use firmware V35 and this TWRP.

Between the rom install and gapps install (when rom install is finished) make a cache cleaning..
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] IDakota:
Do you have the link for that firmware?
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] :
Firmware V35 or another link..

Boot to current TWRP >> Install new TWRP >> Reboot to TWRP >> Install firmware V35 >> Reboot to TWRP >> Install ROM >> Wipe caches >> Install Gapps >> Wipe caches >> Reboot.

(My habit is that rom started I will not enter my account but I will do one a factory reset from Settings..)
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] IDakota:
Nothing, I've done that except to the factory reset and still stuck into the bubbles...
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] :
If you reinstall only the rom -wihtout the gapps- it will start.?

Stupid question: you dont have encrypted phone., yeah?!
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] IDakota:
1. For your first question: It starts either with TWRP 3.2.1 or TWRP 3.1.1

2. I unlocked the bootloader, I don't know if that's what you are asking
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] :
1. 3.1.1

2. Your data partition is not encrypted.?
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] IDakota:
I dont know, how do I check that?
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] :
Nevermind, the flash the rom first with TWRP 3.1.1.
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] IDakota:
It works fine with 3.1.1. The problems is with GApps I think
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] :
So.

Download the --ARM64--8.1--Pico-- Gapps.

Make a factory reset >> Reboot to TWRP >> Install Gapps >> Wipe caches >> Reboot
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] IDakota:
I tried to do this:

Wipe data, cache, system >> instal ROM>>Wipe caches>> Reboot system (now I got the phone working without GApps)>> Reboot into TWRP >> instal Gapps>> Wipe caches >> Reboot

If I do that, the phone is working and PlayStore is installed. However, an error appears: "com.android.settings has stopped"

It seems like an error of Google Play services
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] :
Make a system restore again and it will be ok..
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] IDakota:
but what do you mean by system restore
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] Speaker87:

Hi, I'm new to this and have a new Redmi 4x and want to get RR on it.

I downloaded the 3 files mentioned in OP

TWRP : "twrp_santoni_oreo.img"

ROM: "RR-O-v6.1.0-20180713-land-OFFICIAL.zip"

GApps: "open_gapps-arm64-8.1-pico-20180705"

Then I read this here:

So, I flash TWRP, then reboot into TWRP by pressing POW and both Volume keys (+/-), yes?

How do I know, which FW I have and which FW is necessary to get RR on my phone? I'm kinda lost here.
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] :
The ROM is bad, in the name "land" means not for Redmi 4X, don1t flash this, U need "santoni" and not "land".!!!!

Download this ROM

[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] McJohn.br:

I have flashed Latest version about 2 months back , and no any custom modiffications or still on stock RR kernel.

I've 2 SIMs installed

1st SIM-JIO

2nd SIM-Vodafone

Problem is randomly the network is 2nd Sim goes completely and in SIM CARD option , it shows "SIM CARD MISSING/FAULTY" and I've to restart the device to fix the issue only to get same problem again within 2-3 hours.

What should i do to solve this issue ? I don't think the factory reset will help as I've not installed any 3rd party app which can cause such issue.

Do i need to update the Firmware ?

Right now in baseband version it shows at end- V028.
