[LG V30 Guides, News, & Discussion] TheDannemand:
Thank you. I understand where you come from. And no offense taken ;)

The problem IS a SIM lock (or "network lock" as they call it). But not in the same way you're thinking where nothing works with an alien SIM. Both T-Mobile and LG have confirmed that.

Some details I didn't mention in my opening post (I meant to warn people here, not argue the matter):

1) LG warned me before they began repair that the phone would come back SIM locked, even though I'd included a letter asking if they could avoid it. I also talked to T-Mobile before sending it in, who said to just request an unlock code if needed (obviously that person was clueless).

2) I've seen other XDA users report how SIM locked V30s could connect on different networks, but NOT get LTE. That's what I am seeing too. One of my goals with visiting the T-Mobile store was to verify that there wasn't a problem with the phone itself preventing LTE. But once an active TMO SIM was inserted, everything works flawlessly.

3) I thought the same thing about not running the TMO Device Unlock app with the alien SIM inserted, but TMO's wording in the instructions they sent me are: "Before completing the steps below to unlock your device you must be connected to the internet via a cellular network in order to complete the steps", not mentioning it must be on TMO. And I DO have 3G internet with my Red Pocket SIM. Nevertheless, my second goal with visiting the T-Mobile store was so we could try the Device Unlock app with an active TMO SIM. And regardless of which SIM is inserted, the app reports that the phone is currently network locked and not eligible for unlock. When running this app on an unlocked phone, it shows the date of unlock -- even after a factory reset. They are obviously storing the lock/unlock state on the vendor, modem or carrier partitions or some such place. And on my phone it is in a locked state.

4) There is not much room for user configuration error here: The phone has been factory reset 5-6 times while testing this, with the only configuration being a Red Pocket APN. That same SIM and same APN work flawlessly in my Nexus 5 as well as my wife's V30 (also H932). Even if I mis-typed the APN, I wouldn't have done so 5-6 times -- and I would have caught it during one of the many times I verified the APN.

So I have no doubt that there is some form of network lock in place that is causing this. And again, T-Mobile and LG agree and have promised to solve it.

You are right that LG had no reason to replace the mainboard. But they did replace both the screen and the glass cover. I think it is possible that they sent me a refurbished phone with my IMEI transferred -- which would explain both their warning that the phone would come back locked, and why the Device Unlock app gets confused when seeing a blank (still locked) phone, but T-Mobile's IMEI database claims that the device is already unlocked (as I saw on the screen in the store).

So, we'll see if they manage to solve it or I have to sell this phone as suggested by Chazz.
[LG V30 Guides, News, & Discussion] jaysus145:
Would paying a 3rd party carrier unlocking do the trick? Or does even that seem out of the question now? Before Frankensteining was a thing I did that so I could use an H931 on T-mo. It was $10 well spent as far as I was concerned.
[LG V30 Guides, News, & Discussion] TheDannemand:
Thank you for the suggestion. I'd have no objection to that at all, but various reports on here had given me the impression that 3rd parties aren't able to unlock the H932 because TMO locked it down so hard (as is the case with Sprint, but for different technical reasons). I could be wrong about that, so definitely something to try.

Thanks again!
[LG V30 Guides, News, & Discussion] TheDannemand:
Update: It's been four days since I talked to T-Mobile and they promised to escalate my problem and request that LG provide a solution. They said to expect a response within 72 hours, but I haven't heard back from them.

But yesterday, when I tried popping in my Red Pocket SIM (it's in my Nexus 5 until this is solved) everything suddenly worked: Instant LTE, which stayed all day, even as I drove an hour away across town and worked there for a few hours (using hotspot), went on several errands, and back home all last night. LTE Discovery Log showed how it had switched seamlessly between towers, without ever losing LTE. I was certain they had fixed it, and was much relieved.

Then this morning, it had locked itself again. Phone had been on all night, clearly T-Mobile must have pushed another lock. Or rather: One of the TMO services/apps locked it after pulling TMOs servers. No amount of Network Resets, reboot or toggling Mobile Network settings have worked to get it back. I promised T-Mobile not to make any more attempts with the Device Unlock app as it messes things up for them, but I am sure it it would still say "Ineligible for unlock" even though the IMEI is clear in TMO's database (and listed as already unlocked).

As always, the same SIM gives perfect LTE service in my Nexus 5 and on my wife's V30, with the same APN.

I called T-Mobile Customer Care and was unable to persuade them to transfer me to Tier 2. But they did says to expect a call within a day.

It is almost certain I'll have to go the FCC complaint route. It's sad because T-Mobile is otherwise not a bad company. Probably just a small handful of idiots who got this "bright idea" how to protect TMO phones -- which ends up causing so much trouble for legitimate customers.

[MENTION=3610567]jaysus145[/MENTION]: Which Unlock service did you use? The ones I looked at which support T-mobile unlock cost $75-150 -- and they don't seem to guarantee success.
[LG V30 Guides, News, & Discussion] jaysus145:
I used celllunlocker.net, it cost me $10 to unlock my AT&T version, and took less then a day to complete.
[LG V30 Guides, News, & Discussion] TheDannemand:
Thank you!

T-Mobile called me back yesterday and assured me they were still working on it and they would get this phone unlocked and please sit tight another day. They confirmed there was nothing on the phone's IMEI or my old account that should prevent it.

I'll check out unlocking services if it comes down to it.

Thanks again!
[LG V30 Guides, News, & Discussion] TheDannemand:
Final update on this (and solution):

T-Mobile solved the server side problem with a manager override, so that the Device Unlock app now says "Permanent Unlock approved". But it continued reporting "Unlock Failed" nevertheless. Some say because the phone is already unlocked, personally I think because the servers report the phone as previously unlocked. The app also says "Phone is currently network locked" when first running.

Notably, the connection problem persisted, and T-Mobile (after discussing with LG) said it had to be a bad SIM card or a problem with that SIM ICCID and my phone's ESN. As previously described, I get perfect connection and service using the same SIM in my Nexus 5 and in my wife's V30. T-Mobile said that was all they could do.

I then decided it was time to take the matter in my one hands. After much searching and countless Factory Resets and Network Settings Resets, I managed to get the phone working right with the following steps:

1) Remove Google account to disable Device Reset Protection.

2) Factory Reset from the Service Menu: *#546368#*932# (replace 932 with your model number, though this is likely a T-Mobile only problem). From there SVC Menu - Factory Reset (R&D Only). This takes quite a bit longer than normal Factory Reset.

3) Initial setup with WiFi, no Google account. No APN. Phone shows usual connection slowness.

4) Airplane mode, then WiFi on.

5) T-Mobile Device Unlock app, Permanent Unlock. Got the same "Unlock Failed, but Approved" message.

6) Enter APN.

7) Network Settings Reset (Android Settings - Reset menu). Wait for reset to complete. It may go straight to LTE already here.

8) Power off/on.

After this, everything is back to normal. Instant signal and LTE connection, even after subsequent Factory Reset. It's such a relief :laugh:

Edit: I should add that it is quite possible that not all of these steps are required. Probably the Service Menu Factory Reset was the key to undo what LG had done during the repair. I am merely listing all the steps which I used, and which brought my phone back to life.
[Moto G5S Plus Questions & Answers] D302Thakur:
I have files in my original persist and looks intact, but VoLTE isn't working !

So, I flashed a persist for G5+ from this link (I saw the posts on it that it worked for many G5S+ users) and my VoLTE is working now !

The change that happened is my Baseband changed from M8953_27.36.07.41.01e to M8953_27.36.07.41.01a, but things seem working fine.

I just want my original persist to be corrected as I doubt the new persist which I flashed !

Is there any way this could be corrected ?

Attached is my original persist !

I've seen files there and have had been out of volte. What I do now is restore era and move over persist folder back to root in twrp before I flash every time. Has worked so far

Hi, I have an issue with headphones. From time to time left one stops working. I've checked the basic settings and they seem fine. It happens on all headphones. I don't believe it's an issue with hardware as when I restore phone to factory settings Left headphone starts to work and after some times. A month or so the same thing happens. Is there anything I could check? It's always left headphone.

[Samsung Galaxy Tab S4 Guides, News, & Discussion] Aqua1ung:
Am I the only one who thinks that whoever decided to revert to 16:10 for Samsung's tablets should hang by his/her/xer tongue?!!! Who was the idiot? Did the S2 and S3 not sell well enough? So let's break it down: 16:10 is useless in portrait mode. The only thing this might (might(!)) be good for would be media consumption, specifically movie watching. Why provide the S-pen then? Is this solely a media consumption device? Or is this a productivity tablet? Pen says it's a productivity tablet. 16:10 format says media only. Clearly Samsung doesn't know what it wants, so it decided to screw up both--I mean, who in his right mind would pay upward of $650 to just watch movies (and little else)?

Why, Samsung, why?

Wanna watch movies on Android? There are plenty tablets out there for much less than half of this. No need for fancy pen-compatible screens to watch movies. And why would one need top-notch Dolby quad speakers to watch movies on the train (or on the toilet)?! You want to watch movies in style? Get a man cave, with 150" OLED screens with subwoofers, tweeters, and all that jazz! What loser buys tablets to do professional movie watching? Non-professional movie watching can be done very well on a 4:3 tablet: you don't need a 16:10 screen to watch movies on a plane, or YouTube cat videos!
[Samsung Galaxy Tab S4 Guides, News, & Discussion] AsItLies:
Well, I'm in the other camp, and basically ask "Why oh Why in The Wide Wide World of Sports" does someone want a 4:3 tablet? If you want something the same aspect ratio as your computer monitor... Then Use Your Computer Monitor!!!

To me, the first and foremost reason for a tablet is ... Portability.

To accomplish that we want lightweight, thin, and NOT cumbersome. They need to be easily handled as they are constantly picked up, put down, held in one hand, etc etc.

The 16:10 aspect ratio is easier for that. It's easier to set on the edge of a table, it's easier to (as you say) be a media consumption device. I don't think they are meant to be your 'do everything' computer, that's why we have laptops, desktops, mobile phones, etc.

They are a niche product, yes, to be used sitting on the couch, lawn chair, etc. Where you don't put them down (when using) but hold they device. The 4:3 format is just unwieldy in that regard. And besides, the interface isn't usually a browser, it's an app, which are much more 16:10.

If you want something for productivity, get a laptop, that's what they're for.
[Samsung Galaxy Tab S4 Guides, News, & Discussion] rickyray9:
I don't think 16:10 has much to do with practicality as its lower surface area than 4:3. Lower surface area means less OLED panel, less wacom digitizer, and thus lower costs for competing with the larger 4:3 ipad pro 10.5 in the marketing department.
[Samsung Galaxy Tab S4 Guides, News, & Discussion] Hellberg:
The fact that the Tab S4 has 16:10 format is the only reason I consider buying a new tablet from Samsung. I still use my Galaxy Tab S 10.5 and I like it but it's getting a bit old and the battery has been better. I never considered the S2 or S3 due to it's awful screen format. A tablet for me is 99% for watching videos, so what I want is a great screen (oled) and widescreen format. If I need a portable device to be productive, I'll use my laptop. But that has nothing to do with the screen format anyway, since nearly all computer screens today are 16:10 or 16:9 aswell.

I do mostly watch movies at home of course, on my oled tv and surround sound system, but when I travel I still want a nice oled screen with the right format to carry with me to get the most out of whatever I watch on the go also. I prefer not to use a crappy 4:3 or LCD-screen for that.

And what was said about losers buying tablets to watch movies could also be said about productive work I guess (what losers use a tablet to do professional work?)
[Samsung Galaxy Tab S4 Guides, News, & Discussion] AsItLies:
Totally agree. There's no need to be insulting just because you disagree. Discussing the pro's and con's is the way to go. Thinking you're going to influence mfg's by slinging insults... well, those that do that will get it right back, or just ignored for immaturity.
[Samsung Galaxy Tab S4 Guides, News, & Discussion] Deathman20:
I have a Galaxy Tab Pro 8" model, and love the screen. Sadly the device was buggy like all androids of that age and slowed down, due to programing and lack of memory/storage space. I enjoyed the 16:10 format it had.

Fast forward to 2015 I got a S2 8" model. While I disagreed with the screen display change to 4:3 and reducing the resolution it worked out well overall and have been happy with the device for the past 3 years. Its getting older and wanting something a little snappier a hence why I'm looking at the S4.

That said the screen size change back to the 16:10 format for the S4 is because it reduced the bezels on the top/bottom. With that they could lengthen the screen and still pack the larger battery in the device, as well they increase the screen resolution because its longer. Personally screen ratio doesn't bother me as much as how does the device function, it could have a 4:3 or 16:10 and still I'd be potentially looking at it. Really can't wait to see one in person hopefully next week.
[Samsung Galaxy Tab S4 Guides, News, & Discussion] AM Radio:
graphic designer here. appreciate the 16:10 choice -- my main display is a 34" ultrawide, and i appreciate the extra real estate. was a big fan of the Galaxy Note 10.1 2014 as well, so i'm happy Samsung ditched 4:3.
[Samsung Galaxy Tab S4 Guides, News, & Discussion] carlchan31:
I still had my original Tab S 8.4, had some iPad and minis, and I still prefer 16:10.
[Samsung Galaxy Tab S4 Guides, News, & Discussion] SyCoREAPER:
Let's keep things friendly in here.

I returned my S3 the other day because of the 4:3. I didn't research but also wouldn't have ever thought there would be a 4:3 display. So I ordered the S4 and am picking it up today.
[Samsung Galaxy Tab S4 Guides, News, & Discussion] nrage23:
I just picked a S4 up to replace my S3. I am very happy they got away from 4:3. It is however a perssonal preferencr for every one. Most computers are 16:9 so the 16:10 is better for me.
[Samsung Galaxy Tab S4 Guides, News, & Discussion] dcoke:
Look at EVERY book you see at the store, comics too, they're closer to 16:9/16:10 aspect ratio than 4:3 or 3:2. Same with TV and Movies. Most websites are catered for Smartphones which opt for the elongated aspect ratio over the squat 4:3 one.

4:3 is good for PDFs and digitized textbooks/informational books like DIY books, great for retro games/emulation

3:2 is great for note taking and a bit better at displaying PDFs since it's closer to 8.5x11 inch paper that the US uses and A4 that other places use.

16:9/16:10 great for comics, novels, movies, games and websites.

Either way, the beauty of OLED is that it's amazing at displaying the aspect ratio you want and hiding the cut off bit since it doesn't require backlighting so you don't get those annoying grey (trying to be black) bars on things. Also none of that weird LCD dim screen shimmer issue.

Though, my Note Pro 12.2 (yes that old tablet) is approximately the same size as the margins of loose leaf ruled paper. Which made note taking on it a dream. I still use it for that reason alone. Also because that version of S Note is one of the best versions ever. I'm not a fan of Samsung Note. And I like that size for drawing too. Though their 4 sub-pixel screen really messes with color accuracy and causes pastel colors to look terrible due to that added white sub-pixel.
[Samsung Galaxy Tab S4 Guides, News, & Discussion] Deathman20:
Got to say the 16:10 ratio on the screen while some complain about it, really works incredibly well for DeX mode.

Actually I don't think I've had my tablet out of DeX mode since I turned it on! I just like the function of it considerably more considering the screen size at least for me its worked out very well.
[Samsung Galaxy Tab S4 Guides, News, & Discussion] Masteryates:
For me, 16:10 is a mistake. Love the 4:3 on my Tab S2 8" and can't imagine you could every hold a 10" 16:10 for anything more than a few minutes especially in portrait mode.

Each to there own I guess.
[Samsung Galaxy Tab S4 Guides, News, & Discussion] AsItLies:
That's funny, in that portrait mode is the easiest way to hold a 16:10 tablet. Yes, the bezel does need to be wide enough to put your fingers underneath and a thumb on top, but most tablet makers realize this and make the bezels wide enough.

This is of course with one hand. With 2 hands any of the tablet sizes can be held comfortably. But with one hand, it's more awkward with 4:3 than 16:10 (in portrait mode).

Yes, ea to their own, no doubt there. But holding something, a rectangular shape is easier and takes less leverage, than something that is virtually square. That's not really opinion, that's a bio mechanical fact.
[Samsung Galaxy Tab S4 Guides, News, & Discussion] Masteryates:
I have to disagree with you here AsItLies;77335736. With both 16:10 and 4:3, our tablets are too big to get our hands totally around the device, and therefore we end up having to hold them essentially in the bottom corner, if we chose to hold one handed.

With a 4:3, the centre of gravity is closer to the holding hand than it is on a 16:10. That means the a 16:10 tablet puts more stress on the holding hand, even if the weights of the tablets are identical, as the lever arm is more. The structural engineer sat beside me confirms this.

If you go back to the days of 7" tablets, you would be correct as the your hand could get right around a 7" 16:9 tablet, (like the Nexus 7 2013,) but maybe not a similar 4:3 tablet.

Samsung gets a lot of criticism for the small battery on the Tab S2 8", but for me, its the best of both worlds as its unbelievably light and website don't feel cramped or cut off. :cool:

Like I said, each to there own.
[Samsung Galaxy Tab S4 Guides, News, & Discussion] AsItLies:
See, here's the thing (and I'm glad you describe it clearly), when ** I ** hold a tablet, it's with one hand, in portrait mode, and you are correct, they are (now) too wide to get your hand completely around it like a phone.

So? and that's what I said earlier; The Device Has To Have A Bezel Wide Enough For Your Thumb!

By placing your thumb on the top part of the bezel and fingers underneath (of course not all the way to the other side, too wide), then, as I said, the center of gravity (thus the weight and difficulty to hold the device) is easier, it's less fatigue, it has to be as it's less cumbersome. and unwieldy.

So no, it's not really 'ea to their own', it's simple bio mechanics. If you don't mind it being heavier to hold that way, and you like 4:3, go for it. But the fact remains, one handed, on the long side, is easier with 16:10 (again! as long as the mfg has enough sense to include a wide enough bezel - I returned a huawei mediapad m5 for just that oversight by the mfg... no bezel at all, big mistake on a tablet - although perfect for a phone - narrower, one hand goes all the way around).
[Samsung Galaxy Tab S4 Guides, News, & Discussion] Masteryates:
Ok I'm getting you now. If you are holding in Portrait, the 4:3 has its centroid nearest your hand. What you describe though by saying holding it along its long side, is landscape, which means the centroid is nearest your hand on the 16:10 tablet.

So it's each to there own with respect to tablet ratio and if they use it in Landscape or Portrait. Agreed that bezel size is vital though. :highfive:
[Samsung Galaxy Tab S4 Guides, News, & Discussion] AsItLies:
It's kind of funny ;) Really, and I guess many would say tedious also, but hey, to make things clear sometimes this is what u need to do!

To make the point again, I'm not holding it with one hand on the long side with it in landscape mode, that would mean having your hand ** underneath ** the device.

I'm referring to holding it in portrait mode ** with your one hand on the side ** ... not on the bottom underneath. So it's portrait, not landscape ;)

And when I pick it up and carry it, hand stays in much the same place, just screen off and pinch both sides, easily done with one hand. But that's really not the case with 4:3, as it's like a ** box **. There's really no side to carry it with 1 hand, or hold with 1.

Yes, it's individual, no doubt. But factually speaking, the 16:9 is easier to use and carry around. As with everything, one has to decide what's important to them.

Cheers, glad we clarified it with only having to write 1 chapter of a book, it could have been worse! ;)
[Samsung Galaxy Tab S4 Guides, News, & Discussion] brazcub:
I just got my Verizon S4 and I'm loving everything about it. It is so much easier to type in, handle, carry than my S3. I love this aspect ratio. It way better for reading and running apps on portrait and watching videos on landscape. The thin bezels and lack of physical buttons is great. Also performance is top notch.
[Samsung Galaxy Tab S4 Guides, News, & Discussion] Too51oll:
The only reason I haven't upgraded from Tab S 8.4 to Tab 2 or 3 was aspect ratio. I'm glad they switched back to wide-screen. Can't wait for mine to arrive.
[Samsung Galaxy Tab S4 Guides, News, & Discussion] puppettestpilot:
4:3 format: WHY??!!!!

Your stereoscopic vision (your two eyes) see in 16:9!!

You don't see any TVs or modern laptops or PC monitors in 4:3. Who uses portrait more than landscape anyway. Tablets a so light now-days that they're just as comfortable to hold one handed in landscape as they are in portrait.

The argument that 4:3 is better for web pages because they provide better screen realestate, doesn't take into account the narower screeen width, thus lower 'zoom'.

That is, a 10.5 4:3 tablet does provide more verticle space, but when you compare it to a 10.5 16:9 or 16:10 tablet, with both devices in landscape and viewing a webpage at 100% zoom, the text and images are smaller on the 4:3 device.

I have, and still use, a Samsung Galaxy Tab S 8.4. It still has the hightest PPI of any tablet, including the Tab S4. The only reason I didn't upgrade the the Tab S2 or Tab S3 was the stupid Apple 4:3 aspect ratio.

I look forward to buying the Tab S4 once the price comes down a bit, despite the stupid glass-back.
