(Japan) OK to flash DoCoMo firmware to au model? - Samsung Galaxy S9 Questions & Answers

I have a brand new kddi au SCV38 (Galaxy S9) and a docomo SIM from one of the discount providers (Rakuten). The docomo version of the same phone is SC-02K. au and docomo use slightly different LTE bands. Is there anything speaking against flashing a docomo stock rom to the au phone?

Answering my own question, in case anyone else ever wonders. I've flashed the latest Docomo stock firmware to the au phone and for all I can see, everything works just fine. The only thing I'm left wondering about is use of the docomo LTE bands. Some of these are different from au bands. No idea whether the au phone with the docomo ROM will be able to use all docomo bands. If I ever have an answer to that, I'll post that here as well.
To flash the docomo ROM to the au phone, I followed the below instructions.

Hi Axel,
As you said that you were already successful to install docomo ROM to au model, I assume that you already rooted the device. Could you show me the tutorial to do such thing? I use au S9+ and I want to get a root access, since there's many bloatware I want to remove. Thanx in advance, man.

Sorry, I just saw this. There is no need to root. I just flashed Docomo firmware to the au model, that was all.

I don't know. You could try and if it doesn't work, just flash back the au firmware

so, just to make sure then, you didn't root your phone? or you did root your phone? if you did, could you tell me how to do it? I desperately look for the tutorial to do it since I want to remove bloatwares from my au rom; but none that I can find until now. the rom contains so many apps that I don't need. thanks in advance, mate

thanks for the alternatives bro.. btw, when you rooted your phone, what was its state? my phone is on One UI 1.0 (android 9), baseband version SCV39KDU1BSI1, and security patch is on September 1, 2019; and I'm not sure whether it can be rooted or not, since as long as I know, rooting galaxy s9+ snapdragon is still impossible until now.

it says "In NO way it is compatible with Snapdragon variants including but not limited to American(U/U1/A/T/P/V), Chinese(0/8/6), Hong Kong(0), Japanese(SC-*), Canadian(W) variants"

I should of been more clean in my Question.
The EU Lg bootloader Unlock that is available. would it work on the 815K compared to just a 815 or 815EU.
As far as i can gather from the state of these threads the phones are the same. (besided bands you mentioned) when it comes to unlocking the bootloader.
~Thanks in Advance.
Unlock only works for 815EU models currently.. No other models are supported/unlocked...

815 are "international" version. Yours specifically I could not say. This is the spec sheet from PDADB for that model, but according to that it has a link to Telcel. Telcel is Mexico..

Thank you for the info, it's weird to think that it's Mexico as I am in South Africa. Will have to see once we have root etc what I will need to do and use but thanks for the info. Been weird as my G2 was the D802 international variant. But now I can't find much about the 815P model.

LG-815P is for LATAM, South Africa versions, check it out here: http://www.gsmarena.com/lg_g4-6901.php
What parts are you looking for 815P, at most of times, parts of different variants in the same model are interchangeable, except for frame, housing and loudspeaker assembly.

Do you know - Is it OK to use any H815 Rom on this phone?

I have the version for Mexico and no, you need a ROM for H815P.
The root system can be flashed over any 815 version.

Thank-you Pakitos.
I just want to ask to be sure that I understand you.
Are you saying 2 things.
One is that I must find a ROM for H815P.
The other is that I can use any H815's system inage on my phone.
Thanks,
Hotfingers

Yes there are 2 different things.
1) For the H815P you MUST flash a H815P ROM in order to not brick it. If you flash a H815N, H815TR, etc... your phone will be in an infinite boot loop best case scenario. Not really sure what happens if you flash a different ROM. It may not even boot.
2) When you root, you need to flash a system image that has root injected. Basically a hacked official ROM with the root installed on it. This system image works for every H815 version, so you dont have to worry about which variant you are on as long as it says H815 and matches your current ROM version.
Hope I made myself clear. If not, feel free to ask :fingers-crossed:
I thought 815p was pacific or puerto rico

Flash SM-A520F/DS with a SM-A520F firmware?

Hello there,
Recently I bought a Samsung A5 2017 in Indonesia (model dual sim) and would like to know if it's possible to put a french firmware (so a firmware of SM-A520F) on SM-A520F/DS model?
Thanks for your help

It would be wiser to use dual sim firmware rather than single sim firmware

Thanks but I don't find any dual sim firmware even on Sammobile....
Is there a risk of brick if I flash with a single sim firmware? Or maybe there's another solution?

I was worried too but I tried to use the normal a520f firmware and it worked fine.
BTW Some apps may not work because they will assume you are rooted eg. S HEALTH and secret mode on browser but you can actually root to get around this by editing a line in build.prop
I'm on the same boat, only with the A3: I've bought my phone as an A320F/DS (that's what the box says, and indeed it has double SIM), but when you check Settings--»About phone--»Model name, it only says A320F (without the DS). And then when you look for firmware updates in Samsung website, you only find for the A320F. Might it be that A320F/DS is only a second, alternative denomination for the A320F, being both identical? (Same would happen with the A7.)

It's one year since your question, but still my answer may help others:
I've flashed a SM-A320F stock firmware on my SM-A320F/DS and it works perfectly. I believe that the A series firmwares are exactly the same for single SIM and dual SIM models.
In trying to sort this out for the s7 g935f/ds, I believe I was told that indeed the F firmware is the correct firmware for both 1 and 2 sim models. There was no FDS firmware at all.

The bnd-l24 part should be the easy part.
The firmwares are here. Both the "bnd" and "bond" are OK to use.
But I recently worked with someone else who did rebrand to USA version, and found out the modems do not work correct on us / western frequency's.
And need to know of the phone is unlocked boot loader or not.

SM-G9880 Flashing Question

I recently just bought a S20 Ultra that has a unlockable bootloader. A little while back, I had a Galaxy S9 that I could completely convert the entire device to U1. Is that even possible with this device ? To fully convert the CSC and bootloader ect, to a US model ?

That was then. Each model is specific to a region and can not be flash with software from another region. I.E you cannot flash G9880 with firmware from G988U or G988U1 or the other way around.
What exactly changed from the S9 to the S20 that made that impossible ?

Any luck? I just got one in Canada and it only has 3g ad 4g so I was hoping I could flash a csc file.
So I attempted to edit the band config using QPST and QXDM, but I'm very unfamiliar with both programs and how to actually read and write information to the modem using those programs. Definitely not for the average user. Back in the days when devices had ESN numbers, I used to flash software using QPST and QXDM but there is a lot that has changed with those programs, and I wouldn't even know how to do that stuff today. If anyone has any knowledge about those two programs that can help me unlock all the US 5G bands for AT&T and Verizon that would extremely helpful.
