[LG V30 Questions & Answers] ChazzMatt:
:confused: The only two V30 phones you can't return to stock -- with locked bootloader -- are the only two which don't have public KDZ: Sprint LS998 and AT&T H931. Every other V30/V30+/V30S on the planet you can relock bootloader and flash back to stock with LGUP.

For those two -- H931 and LS998 -- best to leave on US998 after relocking the bootloader. And it's not an issue to sell them them on eBay, as most time that is what people want in the the first place (debloated, carrier unlocked firmware).

No, those are carrier unlocked H931, not bootloader unlocked. Because normally AT&T H931 is SIM card locked to AT&T. Those "unlocked" H931 have had codes inputted so they are no longer carrier locked to AT&T.

HOWEVER, what they don't tell you on Swappa or eBay is you STILL have to convert to US998 if you want updates for that "carrier unlocked" H931 phone, unless you're an AT&T customer. And most people buying a carrier unlocked H931 are probably NOT AT&T customers.

Thus those buyers then come here to find out why they can't get updates. Because they bought a carrier unlocked H931 and you can't get updates without an AT&T SIM card. So, they have to convert to US998 -- so they can get KDZ updates via LGUP. Plus, since they are not AT&T customers they don't need all the AT&T bloatware either. ;)

I've answered that question half a dozen times in the past week: "Why isn't my H931 getting updates?" Because you have to convert to US998, and update via LGUP...

This paragraph is a little confusing.

1) You relocked what and used what KDZ? What 20H? US998 20H? If so, that's fine.

2) Wait, Sprint? You have an LS998? I thought you had H931? Sprint users have to have native LS998. Sprint users can NEVER use an H931. Their phone has to be native LS998. While they also convert to US998, once bootloader unlocked and rooted, they can return to LS998 via TWRP flashable zip. But Sprint users can NEVER active a V30/V30+ that was not first an LS998. Sprint checks IMEI.

Then, to sell the phone, they have to convert back to US998 to re-lock bootloader and they would sell as US998. I wouldn't mention Sprint in the listing whatsoever.

3) Also why are you selling your phone?
[LG V30 Questions & Answers] AsItLies:
" you STILL have to convert to US998 if you want updates"... well I see that as being up to the buyer, I'd prefer to sell it as stock if I could, and avoid any issues they may have. alas.

"those are carrier unlocked H931", I was wondering if that was the case. It seems on ebay they don't specify and some of them are 'unlocked' because they have been converted to us998? It's confusing. I've seen at&t and t-mo devices listed as 'at&t only' and 't-mo' only. Well I'll have to be sure to specify it's been converted to us998.

"You relocked what and used what KDZ?" Oy Vey ;) I guess that wasn't clear, I went to us998 20H (10a - relocked bootloader, then did numerous upgrades and eventually to 20H).

"Are you saying you used your LGUP dump to go back to H931 20H", no, but is that possible? I have "factory" 931 in a zip, they are all img format, can lgup use those to go to h931? That would be good.

"Wait, Sprint? You have an LS998? I thought you had H931? Sprint users have to have native LS998. This paragraph is very confusing. Also why are you selling your phone?" It's complicated... no! it's not! I'm kidding :) I have **3** V30 :) 2 are ls998 (originally) and the other is the H931. I initially got the h931 but decided to go with an ls998 because of possible issues with aosp roms. And because I liked the ls998 ease with aosp roms (the 3 diff ones I tried all booted even when they'd last had 20g on them). Then I liked that ls998 so much I found one on ebay that was described as 'exactly what you'd get from the Sprint store'. Got it and was mfg'd 6 mo ago. Brand new. OEM box. Serial numbers matched ;)

it's complicated - but fun ;) Cheers
[LG V30 Questions & Answers] ChazzMatt:
OK, I understand. You are merely culling your V30 collection, not getting rid of it. ;) Yeah, I'm down to three, whereas I had 5 at one point. One was a former LS998 and suddenly the Qi wireless charging stopped working -- which we use every day. So, gave it to a friend who couldn't care less about Qi wireless charging. Otherwise was mint, converted US998 V30+. I wasn't going to sell it, so better to just give it to a friend who I know will never use that feature.

As for using the LGUP dump to restore back to stock, I think it's possible but I've never done it.
[LG V30 Questions & Answers] 0J1nn:
Hey, I live in Canada and bought a refurbished H931 that I've been using for a few years. In an attempt to remove AT&T bloat and install firmware updates, I followed the instructions here and I now have a working "US998".

The only problem is, I seem to have a lot of trouble connecting to 4G/LTE now. I think it may be related to the US998 missing some bands that the H931 supported like 3G 1700 that my carrier uses (Fizz) (reference here) although I might be wrong (in which case if someone has any idea how to fix it, any help would be greatly appreciated).

Does anyone know if I could flash H933 firmware (found here) instead to fix that problem? Or should I follow the instructions to root in order to flash back the TWRP flashable H931 ROM?

I know this thread is kind of old but any help is welcome. @ChazzMatt maybe? You seem to be pretty knowledgeable about this phone.
[LG V30 Questions & Answers] ChazzMatt:
You can flash to H933 using KDZ, but you have to do a reverse Frankenstein. Flash to H933 Nougat first, Master Reset, and then flash H933 Pie. Use Dev Patched LGUP with Partition DL mode (all partitions).

I have Oreo and Pie H933 KDZ threads but you'll have to find the H933 Nougat KDZ. I can't remember where it is right now. The LG Firmwares site has all that (it's not an LG official site, but a fan site that collects most of the firmware.)
[LG V30 Questions & Answers] 0J1nn:
Thank you so much! I already found the KDZs, just wanted to check if that process was feasible. Going to try this as soon as I can and post back here if it works.
[Samsung Galaxy S10 Questions & Answers] SuperBrolySSJ:
Hi all! I bought the S10 from eBay not knowing it was the Chinese variant.

I have at&t, and it supports all but two of ATT's bands, so I'm fine there.

I just have one question: Will I be able to flash a stock ROM of a different variant through Odin? Like the US Snapdragon variant for example.
[Samsung Galaxy S10 Questions & Answers] SuperBrolySSJ:
So.. No one knows? I wanna verify before I try to flash a ROM
[Samsung Galaxy S10 Questions & Answers] knoxster:
No you will not really be able to do as you wish without substantial customization and editing of the files you want to flash.

What you are asking is as unlikely as being able to flash the TMO version with the AT&T software.. BUT.. AS I UNDERSTAND IT, unlike the other dual SIM variants the unit you purchased comes with a unlocked bootloader out of the box -- whereas all the other variations -- the bootloader is locked so you will be able to flash custom roms down the road which should cover you.

Samsung pay in a few other things those won't work as I understand it.

---------- Post added at 08:23 PM ---------- Previous post was at 08:10 PM ----------

oh and I forgot this nugget of very important information

If you flash anything other than dual SIM variant software you will lose the dual-sim functionality.

Further, I'm not sure how that might affect your micro SD card slot since the hardware is a little different on that device.

Summary: i wouldn't recommend using anything other than dual SIM variant software.

I was wrong however, from like hardware to like hardware there is a way -- see this post. an example of single Sim to single-sim how to do it.

O my good god what are you asking:x You are asking how to flash wortheless murican firmware on unlocked bootloader phone. It will not work though. With this phone you can later have root when it will be available.
[Samsung Galaxy S10 Questions & Answers] VICosPhi:
As others have said, do not do this or you may brick your phone. The model number and bootloader are different between US and non-US Snapdragon versions. I had tried it on my S8 and it won't boot.
[Samsung Galaxy S10 Questions & Answers] FRBonvoyage:
It is only possible to flash other other SM-G9730 models, not 973U like the US models. As there is only one other firmware you can flash, I think you can flash the Hong Kong version as it is closer to the US version than the chinese version is (Chinese and Hong-Kong have the same version)

Hello everyone!

So my friend tried to downgrade his phone from 9.0, to 8.0 and he messed up somewhere so now he's stuck with bricked phone. I think it is soft bricked because i can boot to recovery and to bootloader. I tried to reflash his phone with odin, but i end up with an error something in the lines of write operation failed. Also tried like 3 or 4 diffrent stock roms, nothing worked out.

What i know about the phone:

* Its samsung A8 (SM-A530f/DS)

* OEM lock is still on.

* Debug mode is off (the one in android settings)

* Recovery is still stock (tried to flash TWRP got the same error)

* ADB and fastboot does not pick up the device

* I can boot to the recovery and bootloader (Download mode)

Thank you guys in advance! :D
[Samsung Galaxy A8 (2018) Questions & Answers] mchlbenner:
So you tried to down grade to 8 with Odin?

What what exactly did you try to flash?
[Samsung Galaxy A8 (2018) Questions & Answers] Exs7asy:
I didnt try to flash it, my friend did that, and i took his phone to fix it. So i dont know what he did, he asked me to fix it and thats what i know. As he said to me he used odin to flash an older stock rom, and he messed up somewhere so the phone is bricked now.
[Samsung Galaxy A8 (2018) Questions & Answers] mchlbenner:
Did try a factory reset?
[Samsung Galaxy A8 (2018) Questions & Answers] Exs7asy:
Tried that too, it had no effect, still bricked. In recovery i get some errors. One is "dm-verity verification failed...", and another one "E:[libs_mgr]is_dt_compatible(): firmware info was not valid: '/proc/device-tree/firmware/android/compatible': no such file or directory.

[Samsung Galaxy Note 9 Questions & Answers] melchiar:
I have encountered a really annoying problem. From the moment you have used the Maximum Power Saving mode, it will mess up your push notifications such as mail and WhatsApp.. even if you're back in normal battery mode.. restarting phone doesn't fix it.

The way it messes it up is that push notification don't come true realtime, but rather only when you wake the phone manually..

I'm searching for a fix and will update here. Just don't use the Maximum Power Saving mode.. and if you know more please leave a comment..
[Samsung Galaxy Note 9 Questions & Answers] melchiar:
Hard Resetting the phone didn't help.. I think there must be something else wrong..

Seems like it, but I doubt it is hardware.. it worked perfect couple days ago, until I had to use Maximum Power Save mode.. from then on... But that a hard reset doesnt fix it.. :s.. Anyone else experiencing delayed notifications with WhatsApp?
[Samsung Galaxy Note 9 Questions & Answers] high_voltage:
Search the web and you will clearly see that a lot of phones had/have problems with delayed whatsapp notifications. It has nothing to do with maximum power save mode.

I've been in and out of this mode and experienced no change in notifications from any app. I'm betting you are mistaken in your assumption.

I have the same issue

Maybe it doesn't affect all phones but after maximum power saving mode I get zero push notifications
[Samsung Galaxy Note 9 Questions & Answers] melchiar:
Restarting phone helps I think.
[Samsung Galaxy Note 9 Questions & Answers] Wanmuhd:
possible solution

probably this is a solution, but it is painful

Go to Apps, "reset app preferences"

After that, go to one by one of your apps and setting the "Permissions" again

kindly allow for storage, telephone and contact or you allow all permission.

however need to do it one by one

Hello! I have an Lumia 730 RM1045_1020, in update loop on 8.10.14167.221, and 02040.00005.14391.36001 firmware version. I tried to update do Windows 10 Mobile, but it says that I need to install WP8.1 update(14234) first.

Alright at this point. The problem is when I try to install the update, 14234 build comes with damm Lumia firmware update.

And at 63% gives a 801881d0 error about server problem.

I think that Windows Update downloaded sucessfuly but this Damm Lumia firmware update(that isnt necessary to go to Windows 10) was stored on an server that is off-line after WP8.1 end of support, and stucking update process.

I tried to make an recovery but my usb port seems damaged (Windows gives malfuncioning device error) but Phone works well.

The question is, there is any way to spoof firmware version, or ignore firmware update for Phone go to 14234?

(or intercept conection to Microsoft server)

Or get interop unlock without pc conection on 8.1?
[Sony Xperia XZ3 Questions & Answers] ramy_nassif:
Hello everyone ?

Does anyone know of a way to get Wi-Fi calling and VoLTE loaded onto an unlocked, stock, non-rooted, H9436 ?.

PS: I know as a fact that my carrier supports both of them ?

Thank You
[Sony Xperia XZ3 Questions & Answers] kw0n2k:
Only way is to use Xperifirm to download your regions firmware and flash it.

I know on my previous XZP I had a G8142 dual sim (Hong Kong) and flashed it a G8141 Single Sim (Australia) Firmware without any issues.

Unfortunately Sony Mobile has pulled out of Australia and there no Australian firmware for the XZ3. So I'll never get VoLTE on this phone now.
[Sony Xperia XZ3 Questions & Answers] ramy_nassif:
Did you see any battery life improvement since the second modem is not being used? ?

Is there no risk of bricking it?

It's gonna be horrible having all of my carriers crap on my phone

Maybe you could try using the firmware of another region that has it
[Sony Xperia XZ3 Questions & Answers] kw0n2k:
XZP battery life became one of the best phones I've had after the last Oreo update. Since Pie it hasn't improved much. I would have the phone synced to my android watch all day. By the time i hit bed, i'd have 35% battery life left.

My current XZ3, would be dead by the time i get home from work, yet its supposed to have a bigger batter 3330mah vs 3230mah.

You dont have to use your specific carriers, just your country. Using the Generic Australian ROM I got VoLTE and VoWiFi working on Vodafone AU network.

At this current time no firmware is able to make VoLTE work on XZ3. Simply cause Sony Sucks now.

Might even sell this phone off or return it, as I've only had it a week.
[Sony Xperia XZ3 Questions & Answers] ramy_nassif:
Yeah battery life on this phone is just horrible

My mom has the XZP but she's stuck on Oreo cause Sony mobile abandoned the region, I'm planning on flashing a different region's firmware on my next trip home.

I thought of my carrier's firmware cause in France (my profile still says Lebanon cause I didn't bother changing, I moved to France a couple of months ago) the only unlocked version they sell is the dual sim one, the one sold by operators is the single sim one but they install their own firmware, and also because on their support website that mentioned that the xz3 that they sell is compatible with VoWiFi and VoLTE.

If you return it what would you get?
[Sony Xperia XZ3 Questions & Answers] kw0n2k:
Well I haven't returned it, cause I still don't have my XZP back from warranty repairs. Appears Sony is abandoning alot of regions. Though they are still releasing updates for those phones which is a good thing.

I love Sony Xperia phones, by far the best quality handsets in terms of workmanship, etc. But how they go about their software implementations has a lot to desire.

Hoping one day Sony deploys Carrier integrations like alot of the smaller manufacturers i.e Asus, Huawei, Oppo and Nokia, who are able to enable VoLTE without any specific region firmware.
[Sony Xperia XZ3 Questions & Answers] ramy_nassif:
Yeah Xperia phone are really great, they have a mix of build quality and balance between software features and performance that just isn't available with other phones in the Android world (not talking about iPhones cause iOS is just BAD). I remember when I switched from my Z1 to a note 5, I was so disappointed. Wasn't sure if I wanted to get the Z5 or the note 5, so I decided to see why people praise Sammy, what a mistake ??*♂️.

Going back to the main subject of this thread ?

I hadn't flashed my phone yet cause I had been pretty busy with school and wasn't sure if I should flash my carrier's firmware or not. So last week I got an update. A couple of hours later I went into the settings to tinker with stamina mode. And there I see it. A big banner on the top telling me to activate Wi-Fi Calling. So of course I did but couldn't test it directly cause I was out and about. When I got home (I have really bad reception in my dorm room, when people call me they go directly to voicemail cause I don't have any reception), I tried to see figure it out, but apparently it's just a placebo, it doesn't actually do anything ?
[LG V30 Questions & Answers] Arshk:
I want use the V30 as a streaming audio device and connect it to my HiFi setup via external DAC - audiolabs mini M-DAC. This DAC has an PC/Android OTG micro USB port for connectivity and also a built in battery for optional portable use. I leave the DAC plugged into power and don’t use it as a portable device.

When I connect the V30 to the audiolabs mini M-DAC using a standard USB-C to micro USB cable the phone goes into USB “Power Supply” connection mode. Although the audio works fine with the DAC using the USB Audio Player Pro app it rapidly depletes the phone battery.

I have tried to manually switch the USB connection mode to “Charging” and others but it just reverts back to Power Supply connection.

Can anyone help figure this out ?

I’m guessing the issue is to do 2 way charging offered by USB-C port. Ideally I would like the phone to be able connect to the DAC and receive power From it. If I use a standard usb2 to micro usb cable with a USB2 to USB-C adapter could this stop the phone discharging issue ?

My phone is Rooted if that helps.

Need some advice.

I did look in the forum but couldn't find an answer to my question(s)

1 - I'm looking for a ROM which is stripped to the bone with only what is necessary for the Hermes to function as a phone with Bluetooth and WiFi.

I don't want to install office, voice command etc. just want to run a view programs like setup operator, pocket informant, opera, phonesuite, mobile shell and pocket breeze.

2 - Is it also possible to to build this into a ROM or do I need to install this after a new install manually.

For the commercial programs it's not the intention to install these programs cracked, I have a licence for all those progs so filling in my serials after installation is no problem.
[8525, TyTN, MDA Vario II, JasJam ROM Development] miffymiffy:
To answer your first question, it is best to install a Clean rom, there are many of them around. Shadow and Faria seem to be the most popular. Have a play with them and if they are not stable enough for you then try a WM6 one, Shamanix rom also worked well. My fav WM6 rom was Berds SS_1-25. It was the bare minumim and worked flawlessly. Only my opinion.

For the second, just download the cab files for them and keep them on your storage card. There is no problem with installing them into the rom after the update is complete.

Happy flashing...
