H990DS(TWN) - Upgrade/Refurbish to other Regional ROM version

Good day to all.
I recently bought a V20, a Taiwan version H990DS, so with a TWN ROM. The latest TWN ROM is from last year. Is it possible to flash to the newer Singapore ROM? (SEA)
Like this one : H990ds10e_00_OPEN_SG_DS_OP_0314.kdz (10 april 2017)
I now have :
BASEBAND : MPSS.TH.2.0.1.c3-00027-M8996FAAAANAZM-1.77269.3.79643.3
KERNEL : 3.18.31
BUILD NUMBER : NRD90M
SOFTWARE VERSION : V10c-TWN-XX
MODEL NUMBER : LG-H990ds
I have experience with flasing rom's, but only at Samsung devices. LG is new for me. But I have read the threads around here how to flash a new ROM.
I hope somebody can give me a answer to my question. Thanks in advance!
Greetings from The Netherlands

Hello
someone actually managed to do it, so it seems doable, and fairly easy I'd say.
I was tempted to do it myself, and still am, but then I was just hoping LG would come around with a new update to avoid me all this nuisance...

Hi @buongu
It is just one person who switched his ROM, (@Mattfly93)
On Samsung devices, like the S7, it was a piece of cake switching ROM with ODIN. The risk was very minimal.
I wonder how high the risk is switching ROM with the LG V20 H990DS using LGUP.

there were others too, a guy here (https://forum.xda-developers.com/v20/help/australian-f-h990ds-t3551066) tried out different ROMs to find better suiting apn settings; other guys too, actually a lot of people with the H990DS seems to be into this subject

I see, thanks for the link. I read that topic but must have overseen it
Are you going to change ROM version? And what is the reason to change it?
What are the differences between the Taiwan(TWN) and the newer Singapore(SEA) ROM?

Yes I'm definitely considering a change. Mainly because they keep receiving updates, I don't know the details, but it seems like there have been a few improvements in the audio compartment as well (which is what I care most about), practically every version had them expect for the h990ds twn. SEA seems to be the one getting updates on a regular basis, so that's the one I'm looking at
there shouldn't be any real difference, same apps, same sw release, just a few fixes ahead so hopefully less glitches.

I don't enjoy this kind of tweaking anymore
I used to, when updates were scarce and custom ROMs were pretty much the only way to prolong a smartphone's life... but nowadays companies promise a 2 year support for all their devices, so why do we still need to put up with boring and elaborate actions like this?
and there's a chance we won't see any future OTA either, judging from the info I have found it will still be recognized by your software as from TWN, but the update won't match any of the ones for TWN or the ones for SEA, so from that moment on manual updating is all you have... and THAT pisses me off

I can understand your feelings about this and to be honest, I share them. I am not afraid of switching ROM from TWN to SEA, i think that will go without any problem. But after that it is manual updating, that is something I did not realised. I have to think about this, but the chance I will manually update is big. The updated software and, most important, the security updates can not be ignored. We will keep in touch. Thanks for your opinion.

I would like to know if I can safely use the 'Refurbish' option in the LGUP tool for changing my TWN(Taiwan) Rom to SEA(Singapore) Rom?
Or do I have to use the 'Upgrade' option?

I am currently on the India ROM, which was last updated in January. Also seriously thinking of switching to the SEA ROM. My only concern is if VoLTE will work on it -- currently, I use a Jio 4G SIM. Does anyone know if SEA will support it?
I also have a S7 Edge, and when I changed ROMs on it (from India to UK ROM), VoLTE stopped working. I had to flash back the INS ROM to get it to work again. Does the same happen with LG ROMs? That is, are regional variants of LG ROMs unique?

I can only answer your first question: yes, the SEA firmware fully supports VoLTE

im also thinking about doing this. im on v10e ESA, securiry patch is December. where can i get the DLL for H990ds for LGUP?

All you need is in the 1st post of this thread. Good luck and let us know.
https://forum.xda-developers.com/v20/how-to/v20-kdz-restore-failing-9-completing-fix-t3546817

I took the plunge and it did not go off well! A few observations.
1] I was trying to switch from INS to SEA. Refurbish option did not work -- throws up errors when installation reaches 4 per cent.
2] Upgrade option went off without errors but I ended up with cust id mismatch error after reboot. I think Upgrade leaves a few files behind that are related to firmware region. However, you can dismiss these warnings and use the phone. I also ended up with device failed to decrypt error, but that was sorted with a factory reset.
3] VoLTE (from Jio in India) does not work on the SEA firmware.
4] The SEA firmware felt smoother and more responsive than INS one from January. I also see a few SG specific apps.
5] Have now restored back to the INS firmware by downloading the appropriate KDZ file.
6] Now hoping LG wakes up soon and ports the SEA update to other regions!
Thankfully, the LGUP tool is pretty reliable, and if you are used to ODIN, you will be at home here. I would suggest you go ahead and check it out. Maybe it will work for your region...

I just did the same from TWN to SEA, and surprisingly VoLTE is there!
I see it in the shortcuts, I have no use for it because neither of my carriers support it, but it's there

That's interesting. I did not have this option on SEA. I guess it is carrier specific. From my experience with Samsung S7 Edge, relevant carrier strings had to be present in the CSC file/ folder for VoLTE to work.
If root was available for our device, then perhaps this issue can be fixed.

For India, the latest update listed on that site is from April 1. But I don't see it in the downloads section. Does it take over a month for the firmware to be actually available?!

Does any of these dual sim firmware enable band 66?

At&t galaxy s8 update problem.

Hello guys..
I bought an unlocked AT&T S8 SM-G950U and the biggest problem i am facing now is with software update, my device is unable to fetch any updates from at&t.
I contacted At&t support and they in order to receive updates you got to have a at&t connection or else you'll not receive any updates. No manually dowloadable updates are also not avilable. They suggest to contact samsung service center.
My bootloader is also locked as its an Snapdragon US variant, please can anyone tell me that i can flash samsung stock rom on my s8 or not?? and how to do it? Or any other say to download at&t update?

If you have an unlocked S8, then update will come from Samsung directly and not AT&T. Do you really need AT&T's updates?
1) When you check for update, what do you get?
2) Also what is the build # that your phone has at the moment?

Go to the at&t S8 forums. Firmwares and instructions are posted there. I even linked to the latest Odin firmware if you search my posts.

No i dont want AT&T updates but i received it with AT&T firmware. Everytime i do update it stucks and after a while it shows that your software is up to date and dont check for uodates for next 24 hours.

Yes, you are able to flash unlocked Samsung firmware on your device. Read this and ask questions on that tread:
https://forum.xda-developers.com/galaxy-s8/how-to/snap-guide-flashing-standard-fw-carrier-t3625817
I believe you should be fine by doing flashing from section 1: Standard flashing.

I was using iphone from last 4 years and i just bought S8 because its really beautiful so u can take me as a newbie. It all really confusing.

All firmwares for G950U are here. Some are branded some are unlocked. Choose the unlocked one. Do you need full steps?

Thanks for replying.
Yeah sure it'll be really helpful. If ull guide me out.

Facing the same problem, did you find a solution parkarintl?

Download the G950U1 firmware and install it. Should have all the features, no bloat, and faster updates.

Go to Updato.com and search for firmware for G950U1. Download the fw for the XAA variant. Extract all the files, remove .md5 off the end of all the files, flash them with modded Odin. You'll be on fully unlocked firmware and you'll receive future carrier free unlocked updates.
Latest fw: (QH3)

Installing NON-AT&T FW on SM-J320A... Possible?

I have the SM-J320A, AT&T version, and now being used outside the USA. Specs on GSMArena indicate that this phone is one of the versions of the J3 2016 family: J320FN (Europe); J320F (EMEA); J320F/DD (India); J320A (AT&T); J320P (Sprint, Virgin Mobile, Boost); Galaxy Amp Prime (Cricket); Galaxy J3 V (Verizon); J320M (LATAM); J320G (Asia).
1. So does this mean all these versions are identical in Hardware?
If there is no other option, I will install the AT&T newest version, however I would prefer to see if it's possible to use a non-AT&T FW so I can get monthly updates. So...
2. Can anyone tell me if it's possible to put a NON-AT&T 'open' version stock FW on the SM-J320A... and I would then be able to receive the security updates direct from Samsung...
Hope what I am asking is clear.
Robert

The j320 model has three different soc. The j320a is exynos based. The different exynos models are J320a, j320ag, j320az & j320w8.
But with this device only the carriers supply updates, unfortunately.
Not sure if it's an option, but I activated an att sim for their prepaid service (25¢ per minute or something)... Will never use the $10 I spent for the service, but I can update ota now.
Other than that keep your eyes here, we try to keep the latest firmwares available for download.

That's the best answer I've had on a forum... That makes it clear. So since I cannot really do what I was asking, no problem, I am willing to install the AT&T 7.1.1 version J320AUCU2AQI5. Only issue now is that as said, the phone is in use outside the US currently so cannot get the OTA DL. Is there any way or source to DL the full stock firmware for flash via Odin? Would prefer fully stock version with no rooting, etc.... I have a Macbook Pro for the flashing if it makes any diff.
Robert

Maybe this is what I'm looking for...

Ok thanks again...
Is that completely stock and flashes with Odin?
Any other special instructions needed to flash?
Just asking as it seems there is a lot of discussion on the entire thread and I'm not sure which issues are coming with which downloads.
Robert

Any issues where addressed.
Yes 100% stock.
Nothing special just load all four files in odin and flash it

Forgive me if I sound like a real dingba5, but I can't control myself from asking this. I have developed what can only be described as an unexplainable and illogical obsession with altering my Galaxy Express 2 SM-J327A 's factory condition. From what I know, there's no custom recovery, no ROM, no ROOT. NOTHING for this model. But the Sprint, Boost, etc. variants are all living it up in zip flashing heaven.
So using the same logic my man was using here, which was making sense, could I flash J327P firmware onto my device without ruining my day......

Have a SM-G930V. Want to flash but have no idea what to do.

Hey there, hope y'all are doing well.
I recently purchased a Samsung Galaxy S7 SM-G930V, Nougat 7.0 (note: I live in europe, and it's an unlocked phone). I want to get rid of Verizon logo while booting and all the unnecessary apps connected with Verizon. Plus, as you know Verizon locks some functions like the device maintenance, turning off the backlight of the capacitive buttons, etc, etc.
So, I'd like to have a clean/untouched samsung firmware without any useless apps.
Is androidfilehost.com trustworthy? what about updato.com? (the latter had slow dl speed, and I stumbled upon the first alternative)
PS. by the way, mine reads G930VVRS4BQI1, so one thing that confused me was while loking up for files to download; should I get the G930VVRS4BQI1 which may be the only compatible file for my phone, or do I already have G930VVRS4BQI1, so downloading it would be useless?
Since I wouldn't like to tinker often with the phone system, what do you suggest, flashing or rooting?
Is there any guide for my case for flashing?
I noticed these two on the front page:

which should I pick?
and since the posts were last edited in may and september, where can I find the latest firmware?
and after doing all this, will everything work well, will I get OTA updates?
I would really appreciate someone helping me out, whenever you're free.
Thanks in advance

You can actually cross flash any Qualcomm s7 firmware between all carrier handsets. With your case being in Europe I would recommend the sm-G930U firmware. Which is the carrier unlocked variant of the S7 stateside that has all bands unlocked that the modem is capable of. You will recieve OTA's. It's Odin files are on Updato and SamMobile. AndroidHost is trustworthy.
In your case of not wanting to tinker or have a "need to have" rooted feature on the new device, I would flash the the 930U firmware and enjoy your new non branded system.

I also just bought the S7 Verizon variant, and am planning on using it on MetroPCS. Would you recommend the 930U firmware for me as well? I wouldn't mind getting rid of the Verizon bloat before I hand it over to my wife...

You very well could. I think there is a thread around here specifically about metropcs setup somewhere between the verizon s7 and tmobile s7 forums. I use my 930v flashed to 930U on tmobile.

hey there, thanks for your advice! I downloaded the latest file from here. sammobile"dot"com/firmwares/galaxy-s7/SM-G930U/VZW/
In a moment I was clueless at the "pick country" since there were more than one USA options. so I went with verizon, since my phone comes from verizon.
In the link I mentioned above it reads this This is for SM-G930U from USA (Verizon) which makes no sense to me, how it can be both "U"-unlocked and verizon at the same time... but, oh well, I flashed it 4 days ago and I've encountered no problem, which is all that matters! Hope I made no mistake at picking that file.

Recently purchased galaxy S7 SMG-930V (Best buy version) from a private owner.
I am on cricket and on APN setup LTE and MMS works without issues. Only issue is that upon dialing USSD code i get 'Connection problem or Invalid MMI code' . I tried all options available mentioned in this forum still doesn't work. Which version of SM-G930U should i flash? Main reason i purchased the phone is for Samusing Pay. Don't want to brick or lose Samusing Pay option after flash.
Inputs are appreciated.

Yes Flashing the G930U firmware removes all carrier bloat.
Samsung pay comes with the U firmware.
The last time I was on the U I had bad standby drain. I read somewhere else it has to do with the U not dozing correctly. They may very well have fixed it now, I'm on the latest tmobile 4BRA firmware and it sleeps like a baby right now.

Flashed the verizon U firmware and it did remove all the bloatware. Still need to check on battery drain with Samsung Pay. All other apps are in "Always Sleeping Apps" for better battery performance.
For future reference make sure before flashing new firmware google accounts and lock screen securities are removed/disabled.
Is there a way to back up apps with user data and home screen and reuse instead of installing all over again when a new firmaware is flashed. Spoiled by the root and titanium full back. That was so easy.

As far as I know, no. It's not so bad. I had gotten into the habit of taking screen shots of my app drawer and redownloading. To think now I can just redownload the configuration of apps I had before is as good as it gets. I still just redownload. I like to re-set everything back up just so I know its done.

I haven't tried this method but to backup and restore all installed apps check this Link.

Actually, if all you want to do is switch carriers (same GMail address), then a firmware swap will work.
I have an ex-Verizon (blacklisted IMEI - previous owner)S7 that I was moving to Tracfone (which uses both VZW and T-Mobile towers) - naturally, VZW was a non-starter; however, the UnCarrier was fine, so I used a T-Mobile nanoSIM (Tracfone triple-punch SIM kit includes SIMs from all except Sprint) and replaced the VZW firmware with T-M firmware (Prince Comsy ODIN does the track rather neatly). As long as your IMEI is not blacklisted from the TARGET, such a swap will always work.

Resetting to Stock rom to update

Hi, I purchased an S8 phone in 2017 from US however I was not able to activate Volte on my phone which was required to use Jio sim in India. Last year to enable VOLTE I flashed Indian CSC and some other files and the phone has been working fine with Volte activated.
However I have not been getting any android updates since then and now the phone has started slowing down. I was wondering if it is possible for me to go back to stock settings which will allow me to receive and install any Android updates. Please suggest how should I go about it. Please see some basic information about my phone below:
Model number SM-G950U1 (reflected in abount phone)
Android version 8.0.0
Baseband version: G950U1Ues3CRE2
Any help will be highly appreciated..

Hi, I purchased an S8 phone in 2017 from US however I was not able to activate Volte on my phone which was required to use Jio sim in India. Last year to enable VOLTE I flashed Indian CSC and some other files and the phone has been working fine with Volte activated.
However I have not been getting any android updates since then and now the phone has started slowing down. I was wondering if it is possible for me to go back to stock settings which will allow me to receive and install any Android updates. Please suggest how should I go about it. Please see some basic information about my phone below:
Model number SM-G950U1 (reflected in abount phone)
Android version 8.0.0
Baseband version: G950U1Ues3CRE2

phones are updated in the order of release based on the IMEI and when carriers do the updates themselves. If youre not happy with the speed at which your phone updates, you can get them and manually force them on via Odin and obtain the firmwares via www.sammobile.com/firmwares or i prefer the frija firmware download tool as its about 10 times faster than sammobile directly.
and in most cases you can skip forward several steps in firmwares, but you cannot go backwards when flashing bootloader versions. Your version is S3, so you can flash any S3 bootloader based firmware, but nothing before it

i DO NOT have the slightest idea how legit this site is, but googling the model number and the word "firmware" next to it got me this https://firmware.gem-flash.com/index.php?a=downloads&b=folder&id=14400
at&t has always been weird about making their firmwares available to the public for some odd reason, especially on their weird models
