Call problems - Xiaomi Mi Max 3 Questions & Answers

I ordered my Mi Max 3 from TradingShenzhen and chose the option to have them install the xiaomi.eu ROM. It arrived with TWRP installed, an unlocked bootloader, and xiaomi.eu MIUI 10 v. 8.7.26 installed. I downloaded the most recent xiaomi.eu MIUI 10 ROM (v. 8.8.23) and flashed it in TWRP.
Everything on the phone is working fine except for a persistent problem with calls. Within about 40 seconds of being in a phone call (whether on the phone or through the car's bluetooth) the party on the other side complains that my voice has suddenly changed to being very "tinny" and "robotic" and that they can't understand me. I hear them fine. At all times my signal strength is excellent. Depending on where in the city I am I may be on LTE or LTE+ with four or five bars but the problem persists.
Does this sound like a firmware issue or did I get a bad phone?

Try this fix from @ice0901: Hey I fixed it. Found a post on a thread that will enable VoLTE on Xiaomi Phones. Apparently they disabled VoLTE starting with MiUi 9 due to lack of certifications in certain countries, the US being one of them. To activate it dial *#*#86583#*#*

Thank you for your note. I used the secret code and activated VoLTE, but the problem persists. I called my telecom this morning and a few seconds into the call with tech support the chap said: "your voice has become distorted - I can't hear you" and then he hung up! I was thinking about using fastboot to flash the China Stable and then reflash the xiaomi.eu to see if that clears up the problem, but I am concerned about the announcement that beginning with MIUI 10 v. 8.8.23 "anti-rollback" has been activated on the Mi Max 3 and that you will brick your device if you attempt to downgrade. I also read on the xiaomi.eu forums that xiaomi.eu "disables" the anti-rollback features of the China development ROMs they use. Any thoughts on how to proceed?

Happy to help! Sorry you're going through so much headache. I would suggest starting over as you mentioned and doing the following from @omer1919's instructions from his nitrogen rom thread:
"I suggest to start clean again by flashing 8.8.9 fastboot and then follow the full installation instructions on op post
Installation Instructions:
- Make sure your bootloader is unlocked!
- Boot to fastboot mode
- Format your data to make sure that the installation will be clear using the command: fastboot format userdata
- Flash TWRP Recovery
- Boot to TWRP recovery
- Mount all the possible partitions
- Wipe your data,cache,Internal storage,dalvik DONT WIPE SYSTEM OR YOU WILL BRICK YOUR DEVICE
- Using MTP or OTG copy the xiaomi.eu rom to your device
- Flash the Xiaomi.eu rom
- Wipe cache and dalvik
- Reboot"

Can you tell us what carrier you are using? I also bout from trading Shenzen with the xiaomi.eu rom installed and had call problems at first. First thing I did was follow the advice from this thread. Flash the chinese fastboot then flash the latest xiaomi.eu rom. Then I enable voLTE by typing *#*#86583#*#* into the browser and now my calls work great!

My carrier is Telus (Canada). I followed the advice in the thread you linked (flashed China stable, re-flashed TWRP, etc.) then flashed xiaomi.eu 8.8.23 and this time my call problems were even worse. When I went to dial anyone the phone app would simply say (failed to connect). So I then flashed xiaomi.eu 8.8.9 which other Mi Max 3 users have commented is trouble free, and so far I've been making calls for the past hour to different landlines and mobiles and no call problems. Perhaps there is a problem with 8.8.23, but it is odd that more people haven't had my problems using that version.

UPDATE:
I have now had several messages from other Mi Max 3 users that 8.8.23 caused serious call issues and that reverting to 8.8.9 fixed all their problems. I have now had two days trouble free after reverting to 8.8.9 so I will wait for other reports before considering today's release of 8.8.30 (if it isn't broken why fix it). Besides, MIUI 10 beta testing is now complete for several devices so Xiaomi has begun releasing China Stable MIUI 10 ROMs as of today. I downloaded and flashed the China Stable MIUI ROM for my Mi MIX today and it is working great (despite the odd annoying menu in Chinese). Can't wait for the developers at xiaomi.eu to release their version of the China Stable MIUI 10 ROMs. If the Mi MIX (an older device) has a China Stable MIUI 10 ROM it can't be long before our Mi Max 3s get the stable version as well.

For those of you with call problems using xiaomi.eu MIUI 10 v. 8.8.23 finally an explanation from xiaomi.eu as to the cause. Xiaomi.eu has always 'stripped' the anti-rollback feature from China developer ROMs that they translate into European languages. For the Mi Max 3, 8.8.23 was the first China ROM issued with arb, so in their release xiaomi.eu stripped this feature from the firmware of the ROM. After so many complaints they realized that beginning with 8.8.23 a new modem (required for calls) was imbedded with the anti-rollback feature of that ROM, and by stripping the arb from the firmware you wound up with a ROM that included a modem that didn't work. So on this week's release, 8.8.30, they have left the anti-rollback feature in place, thus allowing the new modem in the firmware to permit normal calls. So you basically have two choices if you stay with xiaomi.eu on this phone - stay on 8.8.9 which is stable and has no anti-rollback protection, or upgrade to 8.8.30 but thereafter brick your phone if you attempt to re-flash an older version.

...then someone try 8.8.30 ? Resolved call problem ?
Can I reverse my actual rom 8.8.23 to 8.8.9 ?

Total disappointed about mi max 3.Bought from mi global store with global rom.When receive it, the calls don't work.I was hijacked to use custom buggy software for flashing rooting and other ****s to do, if i want to use max 3 normally, because there is no official global rom.Never again xiaomi, never.......

First: mi global store is not official Xiaomi store, just a chinese guy, which sell Xiaomi devices from China.
Second: they unlock bootloader unofficial, which is a big problem.
In other words, you got a chinese Mi Max 3, with unofficial unlock bootloader and fake ROM. Buy official global version and anything works perfect out of box.

Plz how can I get official global ROM for my mi max 3. I am in Nigeria and bought the unlocked global version of the phone last two months, August. I need Ur help, pls

Does a global ROM for this phone exist?

Because according to my online seller it does.
Question roughly translates to: Which ROM? If I encounter any issues can you help to claim the warranty (to China)?
He answered "Global ROM. Yes I can help"
But the question now is: does a global official stable ROM even exist for this phone? Isn't it China-only?
I bought the MI 5s Plus 64 GB in China a few days ago. I can confirm you there is no Global ROM yet. However, the stock Chinese ROM has English as language. You can also install Google Play Store and uninstall any bloatware default apps.
There is an Unofficial EU ROM if you wish to try.
https://xiaomi.eu/community/forums/xiaomi-mi5s-plus.149/
I got the Mi5s (not plus) last week and it shipped with miui 8 global rom including pretty much any language not just english and chinese!
Please note that the MIUI rom could be manipulated by the guy who installed it. Currently there is no official global rom from Xiaomi for the 5s. All the currently sold ones with Global ROM are unpacked by the seller and reinstalled with some MIUI rom, which could be manipulated. Also OTA updates won't work with those mobiles
I'm also waiting for an official global rom, it's just not sure yet if there will be one.
I bought this phone with chinese rom and I was going to flash global rom as soon as it is released. but I'm not planning to change the rom anymore. I have debloated it myself and I'm happy with it at the moment.
I have to admit, I'm pretty disappointed. I honestly didn't realize I wouldn't be getting official MIUI.
Is there any particular way for me to see if there is any harmful backdoor software installed? So far this "global ROM (8.6.10.0)" seems solid enough, all functions seem to work except that when I go into the updater and try to choose an install package it tells me to install file explorer first....
I'm downloading the stable, official Chinese ROM right now... Not sure if I'll install it or not though...

I got such a vendor "global" rom, tried to flash with official chinese zip, did not work -> verification problem.
unlocked bootloader, flashed twrp and xiaomi eu rom based on official chinesese developer rom..
Will wait for global rom as chinese rom is too much bloated..
If they launch it in india(hope so), global rom will exist, otherwise xiaomi eu forever...

All good for me except fingerprint (may be due to plastic cover.. will try later after receiving my tempered glass)
I have an mi account which i used for unlocking..
You can create an account then use this link
http://en.miui.com/unlock/
Once they approve they will send a mail with link to download the unlocking software
You should install that, then run it and login in that..
You can unlock it there
install required tools- fastboot ... drivers.. (for me standard android sdk was sufficient...)
After installing those..
You should shutdown device completely then hold volume down and power button at same time to enter fastboot mode
Then connect mobile using cable to your pc
below command should list your device once connected...
fastboot devices
Download the twrp from link given here http://forum.xda-developers.com/mi-5s/development/recovery-twrp-3-0-2-0-t3480133
make sure that its for proper device (mine is mi5s not plus)
if it a zip extract the img file.. then type command
fastboot flash recovery twrp.img
then to boot in to recovery
fastboot boot twrp.img
my twrp defaults to chinese so to change language refer video here https://www.youtube.com/watch?v=KOhR92EKD7A
download xiaomi eu for your device
from here https://xiaomi.eu/community/threads/6-10-20.35693/
Then follow standard twrp flashing guidelines..
You can find it everywhere ( >>> Factory Reset >> Wipe select partitions >> install from internal memory if you already copied it there OR sideload using adb from pc)
PS: (I had formatted system partition as well without issues)
my back button was not working properly but after reboot it was ok..
Thank you very much [email protected] for the explanation.
I will try the procedure today evening when i'm home from work.
Update:
worked fine for me. Thank you very much!
Thanks for all the replies, but went ahead and bought the Note 4 instead. Camera is my only complaint against it, otherwise it's a really great first experience with Xiaomi!

I just bought 5s 128 GB in Malaysia which is directly import (not from official dealer) with Stable Global ROM 8.0.10.0.0 (MAGCNDH) Build MXB48T as per attached. There is no bloatware and quite stable.
Can anyone confirm it is a real global ROM from Xiaomi or a modified ROM?

The additional 0 at the end of the MIUI version and the CN in the MAGCNDH shows that it is a chinese ROM which was manipulated.
So you won't be able to update it, and I at least could not unlock the bootloader because the xiaomi tool did not recognize it as a xiaomi phone....
So I built me a deep flash cable and flashed chinese official ROM, unlocked it and flashed TWRP and xiaomi.eu ROM....

Any Guide for that? Or a video guide?
Check this here, source: http://en.miui.com/thread-390697-1-1.html
Here is what I did to get an official ROM instead of the malware infected 8.6.10.0:
At first I have to mention that using the EDL Method is very dangerous because you will probably brick your phone if it goes wrong.
If you are not sure about something better ask here before doing anything wrong. The phone should have a full battery and save all your files because the phone will be wiped during the proccess.
Step 1. Download the latest official MIUI Fastboot ROM for Mi 5s:
http://bigota.d.miui.com/V8.0.10.0....AGCNDH_20160805.0000.29_6.0_cn_49ab3a5120.tgz
(!!! Important - When flashing the ROM with the Xiaomi FlashTool in the step 3. you have browse into the /images Folder. - Browsing into the wrong folder and flashing wrong files will probably brick your phone !!!)
Step 2. Turn your phone into EDL Mode:
http://xiaomitips.com/guide/how-to-put-mi-5-into-edl-mode/
(Use Option #1 - Option #2 and #3 does not work)
Step 3. Use this Tutorial to flash the Fastboot ROM to your device. Use Method #3 , as Method #1 and #2 does not work anyway with the fake ROM 8.6.10.0.
http://xiaomitips.com/guide/how-to-flash-miui-8-fastboot-and-recovery-rom/
( Skip Step 4,5,6 because your phone is already in the EDL Mode)
This helped me out go get the official Chinese ROM 8.0.10.0. Out of this ROM you can use the MIUI Updater function in the phone to install any other official ROM for the Mi 5s.

There will never be a global ROM for this phone.
It's a China only device.
I still have a little hope that they might start to sell it in India, which typically means there will be a global rom. But so far nothing is announced, so at the moment there is no hope for an official and signed global rom.

My Mi 5s has the same ROM and it works flawlessly. Benchmark results are far ahead compering to those from reviews on YouTube. I was able to unlock bootloader in first try, no problem. If you use Windows 10 make sure to load proper drivers. I don't believe that any reseller is able to compile such perfectly working ROM. It must be Xiaomi that stay behind this, but this is what I believe. As you sad all languages are there and even some you don't find in official global ROM. I will keep this one until official global I released. Be patient.

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.

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).

[Q] I have a mountain of questions before I decide to buy this phone :)

Hello everyone,
I have got a mountain of questions that arised from reading the forum and a lot of different topics.
I'll have numbers on them, so if you can/want to only answer a few of them you can refer to the number.
1. I've read about this ARB quite a lot, what's the deal with that if I want to go to a custom rom?
2. I understood that it matters where to buy the device in terms of an unlocked bootloader (TradingShenzen seems like a good place to start). But if I can't get my hands on a phone with unlocked bootloader, can I unlock it myself?
3. I'd like to go with the xiaomi.eu rom, any advice on how to get there? What I mean is, should I choose a CN model or is a Global model better, does it matter? What steps to take regarding TWRP and avoiding ARB, etc.
4. What does GSI stand for? I haven't found any thread explaining what that means, and I'm quite new to xiaomi devices (would be my first one).
5. I've also seen that there are quite a few different variants of this device, do the roms for it just work on all of them or do I need to check if the model is supported? (That seems to be a bit different to other phone vendors)
That's it for now, please don't kill me if some of the things have been answered before, I haven't found an answer to the questions so far (the infos that I got so far were insufficient)
Cheers,
Zacki
1 Google introduced ARB, a safeguard to not create an older version of the system from the currently released. If you install the official older version of the system for a new one, you will wall your phone.
Does not apply to Custom ROM
2 You can unblock the bootloader yourself on the official xiaomi website. It takes about 300 hours
3 unlock the bootloader, install recovery, install xiaomi.eu. Global rom is more stable, but xiaomi.eu has more personalization options. Recently, xiaomi.eu does not cause problems on Mi Max3, but it causes problems on other models.
4 GSI https://source.android.com/setup/build/gsi
5 Mi Max3 Global 4gb RAM 64gb internal memory,
Mi Max China 6gb RAM 128gb internal memory
You can install the Global ROM on the china version if you have unlocked the boootloader, and remember about the ARB. Otherwise, you will wall your phone
The Global version is popular.

Thanks for your reply.
@1. Interesting to see what Google is up to with things like this...why would they want this?
@2. Thanks, but whoa that's quite some time...and I guess I can only trigger the 300h AFTER I bought the phone, right? (Why so many hours actually...?)
@3. I've read about the changes they made to the rom and I like that. But what do you mean with being "less stable" than the global rom? In what way? I'd like to use that as my daily driver if I get it (not the weekly builds of course).
@4. Will have a look, thanks :good:
@5. I was actually looking at the 6GB/128GB version of the phone, if I can convince my wife to allow me to spend ~260€ on a phone (I'm currently a student ).
In this case, I'd already have an unlocked bootloader and if I want to install the rom from xiaomi.eu, there should be no problem, right? Also regarding ARB, this should be fine, right?
And in what ways are the CN and the Global versions different other than the rom? Are there differences for the supported bands or radios? I live in Austria, can I use the CN model here without any downside?
Edit: I'm having a look at this particular model, it would be available with CN firmware or with Global firmware. Would that still account as CN model in this case?

Google thinks people should use the latest system because it provides better security.
Xiaomi introduced a long wait time to unlock the bootloader, because dishonest sellers offered CN versions outside of China and India by installing the Global system on it. The CN version is only for China and India.
Xiaomi.eu provides its system every week. Contains various patches and additions. Sometimes something does not work, payments, BT paired in the car, notifications etc. In my phone, the last two versions do not work Gmail notifications. In today's version, people write that OK Google is not working.
If you unlock the bootloader, you can install xiaomi.eu. The ARB will be kept at the level of the official system you had.
The CN system contains only Chinese and English. It does not offer Google Play, it also contains full Chinese software.
Version 6/128 is only a CN model. If the seller offers with the Global system, it means that he has unlocked the bootloader and installed the Global system. You naturally lose the Xiaomi warranty.

So the xiaomi.eu roms don't have any of that ARB stuff, good to know. Could I technically install an older version of that custom rom without triggering the ARB or is that not possible? Just so I understand that.
And how is that with other custom roms? I've read in some threads that you have to make sure you have the correct ARB if you want to flash that particular rom, why that?

I'm not worried about the warranty but more about the specifics of the device. Is the CN model different in any way that it may not work properly with the providers in europe? Or things like that?
And sadly that vendor does not seem to have that version in stock at the moment, so I was thinking of getting the regular CN version of the device, that's why I'm asking
As for xiaomi.eu it does not contain ARB, but there are exceptions. If the phone gets an update to android 9 - xiaomi.eu must use the full original xiaomi firmware from ARB. The next versions on the same adroid no longer have files responsible for ARB.
Current level of ARB = 4 from Oreo to Pie. What you can not do:
to install MIUI9,
to install Miui Global on a CN version phone with a locked bootloader
block in the bootloader if you have Miui Global on your CN
install Miui China on a Global phone and block the bootloader.
Custom GSI roms do not have an ARB, you can install anything.
Mi Max 3 in the CN version in addition to the system and memory does not differ from the specification from Global. Will work in Austria.

So if I get the phone with Android 8.1 and I want to get MIUI 10 (Android 9) I need to update with the official rom and then flash the xiaomi.eu rom?
And while we are at that, if I buy the CN variant, do I have to upgrade to PIE with the CN official rom or can I also do this with the Global rom to get ARB to 4?
And what't the deal with the developer versions of the original roms? I've read something about them but would that help me in any way?

Ok but once the bootloader is open, why relock it anyway?^^ And I've read that on the xiaomi.eu roms you can not accidentaly relock the bootloader.

Custom GSI roms do not have an ARB, you can install anything.
Mi Max 3 in the CN version in addition to the system and memory does not differ from the specification from Global. Will work in Austria.

Working in Austria sounds good, but what exactly do you mean with "in addition to system and memory". The system and memory are different in the two versions and the rest is the same? Is there anything I should be aware of while using the phone?
Oh and by the way, thank you for answering all my questions
So if I get the phone with Android 8.1 and I want to get MIUI 10 (Android 9) I need to update with the official rom and then flash the xiaomi.eu rom?
And while we are at that, if I buy the CN variant, do I have to upgrade to PIE with the CN official rom or can I also do this with the Global rom to get ARB to 4?
And what't the deal with the developer versions of the original roms? I've read something about them but would that help me in any way?
Found that website in another thread: Link

it's not like that. You do not need to update the system. Xiaomi.eu is built with miui china developer extended to additional language translations, optimizations of softu for Europeans and a few additions that occur only in the Chinese version of the miui.
The whole system, firmware and kernel is miui china. If you install xiaomi.eu then you install the entire system, with the firmware and kernel. They are suitable for the android version.
You can have miui global Oreo and install xiaomi.eu Pie. Everything will be updated.
Miui Global is available in Stable and Dev versions. Dev-Beta is a development version released every week, contains the latest security, system fixes and errors detected in the Stable version, as well as new additions that are tested and do not always have to work correctly (like the development version of xiaomi.eu). As developers will correct detected errors, the stable version is created.
I just installed myself Global dev. I like it more than xiaomi.eu. Everything works so far. I usually use Global dev, and xiaomi.eu tests once in a while.

Some block the bootloader from ignorance or inadvertently.
When installing a new ROM by MiFlash, you have the following options:
install and block the bootloader (by default selected)
clean everything and install
save data and install

the parameters of the telephone accessories and the frequency ranges of the network are the same. The difference is 6gb RAM, 128gb Internal memory and MIUI china.

Ok sounds good, so if I want to go for the xiaomi.eu rom, I can just go ahead an flash that thing and I'm good, that's what I understood. Is that correct?

Interesting, because I've read somewhere that the normal and the dev version are more or less the same, just that you have to use the dev version in certain situations to "unbrick" because of something with the bootloader (but I don't actually remember the details).

I've also read about that tool, is it required to flash roms or can I do that via TWRP? And why would such an option be selected by default...? I've already seen someone brick his device because of that

Ok got that, and the MIUI china doesn't really matter once I'm on the xiaomi.eu rom.
Good, I think I might actually see that I can get the cash together and order the phone Getting excited now.
Any resources I should read before I might do something stupid?
If you have an unlocked bootloader then you install twrp and flash xiaomi.eu

Using dev to unlock the bootloader affected old phones. Currently, it does not matter. Rom useful as well as Stable.

Miflash is used to install only official miui Rom, you use the rom .Tgz package
It installs through Miflash with the cleaning option. It does not leave garbage in the old system.

If you have xiaomi.eu then china rom does not matter.
You can look for a seller who offers a phone with downloaded xiaomi.eu or miui global - to choose from
in the past, the sellers offered the china version.

So last question for now (I hope ), if I decide to get the EU version instead, can I still unlock the bootloader or is that only possible on the CN versions?
you can in any xiaomi
Bartos81 said:
You can unblock the bootloader yourself on the official xiaomi website. It takes about 300 hours

I've just read in another thread that it is 720 hours that's full 30 days... I hope it's more the 300 hours you said but I fear I might have to wait a full month for that...
Can anyone confirm this number of hours?
Cheers
Usually it is 720 hours, but I checked it every now and then, after 4 days, this time has decreased by half.
It's 100% not decreased or changed it 720 hours. Unless you had a mi account before an unlocked a phone

That is an interesting note. I created an account a few days ago, when I ordered the phone. Does this already count as "having an account before trying to unlock"?

You can switch from chinese to global rom(or indian rom if you want inbuilt call recording option) after unlocking bootloader and debloat it all after rooting..Or maybe just flash custom roms .

Hello Robert
I have ordered CN version Oct, and i have been using it ever since. Out of the box you will get 18w charger with adapter which is very good, i live in Bosina, both sims are working fine 4G works too. There is not much to be worried about in CN version it works great it gets latest builds of MIUI (compared to other versions). Only thing that was kinda a nitpick and kinda annoying for me from start is that you get few standard Chinese apps that you can delete, and some of main Mi apps keep giving notifications in CN like mi videos and very other few, but rarely and they can be blocked. When you power on a device for a first time and creating Mi account you will have to install gapps which you can do over integrated mi store as i can remember (just type google no need for Chinese fonts). After doing that and logging into your google account i recommend you to unlock bootloader, you will have to make a request for unlocking it takes 160+ hours for it to get approved. Install xiaomi.eu rom which is cleaned and optimized CN miui for global users with xiaomi devices and regular updates and builds. I am currently using xiaomi.eu rom its fast, it has also ability to update it with updater in system. Anyway it is up to your preference what you want from device, you can try to install global firmware without unlocked bootloader you can try, if you want or some other custom rom with unlocked bootloader.
Best regards

Question OnePlus 11 cross flash bug

Hello, so recently I tried flashing ColorOs A11 build on my OnePlus 11 CPH2447 Indian build with Fastboot Enhance application. The process was breeze and phone booted with Cos A11 but than I faced two bugs -
1. Wifi can't find any nearby connections, if you try to tap on refresh button, whole system freezes for 3 seconds.
2. When you insert sim you get this error "You are using a device which is only sold in China. It's communications functions will soon be restricted. Please go to Official Oneplus website and contact customer service for help"
So again I tried to flash Indian rom CPH2447 and the second no. problem still exists. I tried factory reset and everything but no solution. Atlast I visited OnePlus service centre and upon checking they said we asked our technical team and now waiting for their confirmation.
This is just a heads-up to everyone that the problem is not only limited to Chinese bought OnePlus 11, it can even occur in your device too if even once you flash any Coloros build of Oneplus 11. My phone is Indian build ( CPH2447 ) and upon asking a friend he confirmed with OnePlus team that crossflashing in OnePlus is only supported till OnePlus 8 and 9 series.
have you tried using fastboot enhance to remove all cow* partition from device?

Why would you flash ColorOS in the first place? What is so interesting about chinese region rom to flash it?
Seems like there is STILL not enough (sarcasm intended) information here on XDA and another topic suddenly appears like a wild pokemon.

The real reason is performance, as I checked that in some benchmark apps cpu can perform really high on COS compared to OOS rooted. So just to be sure I flashed it
Yes thats how I flashed it
