[LG V20 Guides, News, & Discussion] Alibaba0101:
The US998 V30 that everyone including me is using does not have band 30 or 71. Both are disabled through the lack of the correct modem firmware. The tmobile variants all use different rsa keys and have been much more difficult to root or get roms for, but they would then have the right radio band enabled for tmobile. Within the last few days there has been an root and bootloader unlock method for the h932. Apparently its difficult and risky right now.

I was using the h918 on at&t because it was already bootloader unlocked via fastboot, but the signal was horrible on at&t.

For the v30, the options are 1) use the carrier phone H932 and deal with the bootloader unlock issues or 2) get the unlocked US998 and deal with bands missing band 30 for att and 71 for tmobile

For the v20, the H918 was the last of its kind with unlocked bootloader, removable battery, sdcard support, and the right radios for tmobile. You just had to deal with lack of updates from the carrier...ie still no oreo even though att/verizon/sprint varriants all have oreo now. And the different RSA keys have prevented cross flashing of roms.

Hope this helps
[LG V20 Guides, News, & Discussion] runningnak3d:
Rooting the H932 is as safe as rooting the H918 now...

What's different on the Sprint v30 ? ARB 0?
[LG V20 Guides, News, & Discussion] runningnak3d:
If you mean why can the Sprint V30 be rooted and not the Sprint V20? ARB is definitely part of it...

There was a massive hole found in the Oreo abl (aboot) on the V30 that allowed them to flash a bogus unlock.bin file to unlock their bootloader if they flashed the US998 abl.

Just like the V20, if any of the carriers decide to increment ARB, that hole goes away. It appears that they are allowing people that unlocked their bootloader to keep the unlock even after patching it, but if ARB is incremented and you aren't already rooted, then you won't be able to rollback to the version that has the exploit.

So, my advice stands. If you are going to buy a V30, either get the US998, or get an H932. It is up in the air as to how long the others will be rootable, so if you had to send your phone back for a repair, and they ship it back with patched firmware that had ARB incremented, you are boned.

-- Brian
[LG V20 Guides, News, & Discussion] zeusofyork:
Hahah where theres a will theres (sometimes) a way. Well unintentional or not that's pretty sweet. Sucks for people finding out after the fact though. I just figure they should allow people to unlock but sign some release saying you accept xyz if something bad happens. Win win in my book.

Yeah that's what happened to me. I did a test flash for Alpha and bricked my v20. Got it back and had from LG and it was ZVD. I'm looking at my options now.
[LG V20 Guides, News, & Discussion] ttabbal:
I really wish OnePlus or another owner-friendly device maker would make a device I want. Treble helps, and hopefully someone will make something like that. No more sealed batteries for me. I would probably still be running my Nexus 6 if it were not for that. Though it was getting a bit slow toward the end. I could replace the battery, but it's tough to find good replacement batteries for these sealed units. With the V20, some reputable battery makers have models available and it's easy to swap them should I get a bad one. I don't have to heat up the glue to open the thing.
[LG V20 Guides, News, & Discussion] Alibaba0101:
Unless you are on tmobile and only plan on ever using tmobile, i wouldn't by another tmobile phone. They have become impossible to sim unlock and they used different encryption keys making them difficult to work with. And if I'm not mistaken they were the only carrier to increment to arb1 causing even more headaches with rom flashing...and what started this whole post. The v20 h918 still does not have oreo. The last one possibly. Probably because they locked down the phone so much with different rsa keys and radios that they can't use the stock roms that lg puts out?
[LG V20 Guides, News, & Discussion] KUSOsan:
Yeah I was hoping there was a way to use the band 71 on the unlocked phones but how are they impossible to sim unlock? All I did was run the unlock app that comes with the TMobile firmware
[LG V20 Guides, News, & Discussion] Alibaba0101:
If you want to get a phone that supports band 71, then most likely you are already on tmobile and can have tmobile sim unlock the phone for your before you root it or unlock the bootloader.

If you don't have a tmobile account, the problem is that there is currently no vendor that supports sim unlocking tmobile phones that use the tmobile unlock app. Tmobile has switched to using their own unlock app which only works with tmobile customers.
[LG V20 Guides, News, & Discussion] runningnak3d:
There are several places that will SIM unlock T-Mobile phones for $10.00 or less. If I can get enough EFS dumps of before and after I will eventually be able to figure out how they do it.

In the meantime, I think $10 to have your phone unlocked is not unreasonable. I have tested two separate services, and they both worked flawlessly. One was used on the V20, and one on the V30.

-- Brian
[LG V20 Guides, News, & Discussion] Alibaba0101:
I agree, $10 is not unreasonable. With the v20 H918, i went through pretty much all of them before giving up. I ended up selling the locked v20 h918 and bought one that was already sim unlocked. Every vendor that claimed they would do it, ended up giving my money back. There were a few charging as high as $40.
[LG V20 Guides, News, & Discussion] suhridkhan:
considering the amount of time TMobile is taking to open the Oreo update for h918, I have a feeling that they are gonna increase the ARB number and add some other craps to lock down the device further. :(
[LG V20 Guides, News, & Discussion] runningnak3d:
They can increase ARB as much as they want. As long as they don't remove the ability to unlock the bootloader, then I will be able to root it (same goes for the H872 and H932).

Now, if they pull fastboot oem unlock -- then we are boned .. at least as far as rooting NEW phones that have had ARB incremented, and oem unlock pulled. Keeping root is just a matter of not flashing recovery.

EDIT: and it isn't a good sign that the TMO version of the G7 no longer has an unlockable bootloader (at least not via fastboot).

-- Brian
[LG V20 Guides, News, & Discussion] KUSOsan:
Oh didn't know their app only worked if you are a customer.
[LG V20 Guides, News, & Discussion] Alibaba0101:
Apparently the tmobile sim unlock app checks into the tmobile server to perform the unlock which checks the customer account. There apparently is no way to enter a sim unlock code like all of the other phones.
[LG V20 Guides, News, & Discussion] jimenezboy:
I agree. Unlocking T-Mobile phones that have the simlock app is really stressful. I had someone ask for $60 only to refund the money when he couldn't do it. Some sites were charging up to $150 for the same. I was helped by someone on this forum who unlocked it for free. That unlock method is probably what [MENTION=3167089]runningnak3d[/MENTION] is talking about. Long live XDA.
[LG V20 Guides, News, & Discussion] br0adband:
So I got the V20, it's in far better shape than I was expecting, just a few nicks on the top and bottom plastic end-caps, no damage to the display glass at all. Even still has the plastic protector on the rear camera lens cover as well so that's something I suppose. I missed the DT2W/DT2S and am already right back into using it like I never stopped since I first used it with an LG G2 many years ago.

Android build is 10s (January 2018 security patches) so I'll see about what my plans are going to be later. Original manufacturing date November 2016, the battery says the same thing so I'll do some testing with this original battery and then charge up the new one I got (August 2017) and test that as well and see how things work out then start swapping as needed.

Seller included a cheap 5V 1A microUSB charger as expected so I complained about it and the fact that I can't even use it with the V20 as the plugs are mis-matched; I doubt they'll send me an actual USB-C charger but it can't hurt to complain. The threat of negative feedback might spur them into action. I have a Monoprice heavy gauge USB-C cable which is giving me the full 2.1A from the Apple 2.1A charger as measured by Ampere so I'm good to go there.

So far so good, nice to have a decent smartphone again, and now I retire the Kyocera Duraforce PRO I was using which isn't a bad device but it's just so damned slow and laggy at times. The Snapdragon 617 that powers it is more than capable so it's the firmware that sucks and I can't do anything about that, everything that can be disabled is so, it'll just be a spare if needed.

And yes, it was T-Mobile locked when I got it but since I'm a T-Mobile customer I fired up the Device Unlock app and requested the Permanent unlock, granted, rebooted, done so that'll help increase the value if I decide to sell it at some point in the future.

Now the fun begins... :D
[LG V20 Guides, News, & Discussion] PhantomGamers:
Out of curiosity, what would happen if they pulled fastboot oem unlock and a device with the bootloader already unlocked updates to the new bootloader? It'd stay unlocked?
[LG V20 Guides, News, & Discussion] Alibaba0101:
the plastic chin and top pieces can be easily purchased form ebay. Just make sure you look at the pictures and see connectors where yours has them already.

10s is arb1, so if you are looking to flash any roms, they need to be 10p and later.
[LG V20 Guides, News, & Discussion] br0adband:
Yah, and I'm returning it, sadly. The rear cameras aren't focusing at all, they are completely blurry and I don't know if there's some issue with the cameras themselves or the laser focus or whatever. The images produced are also very fuzzy overall, cloudy, and I've done what I can to improve it - I removed the lens cover, made sure it was totally clean, checked the actual lenses on the camera assembly and they're clean too, made as sure as I'm able that the laser detector and the other one (contrast or something, IIRC) were not blocked in any way, blew some compressed air on them to (hopefully) remove any dust that could be an issue as well.

Here's an image I snapped using the Duraforce PRO I have compared to the V20, it's pretty obvious which one works and which one doesn't so the phone has to be returned. I'll look for another H918 after I get the refund processed but that could be 2 weeks or longer with the way my luck goes.

And yes I found info from people saying the primary camera can sometimes get "stuck" and a smack on the rear of the V20 can sometimes shake it free so I gave that a few shots, no luck. That wouldn't account for the hazy cloudy quality I get with the pics I've taken too. Auto, Manual, makes no difference, the focusing simply isn't working as it should.

Ah well, my luck ran out this time, hopefully I'll get one that's in great shape and has no such issues with my next attempt.
[LG V20 Guides, News, & Discussion] raduque:
US996 (not USC) still doesn't have it either, and probably won't. It hasn't even gotten any security updates in years.

Almost no OEMs do this because most people want their volume buttons to actually, ya know, change the volume. Crazy, right? :P

Hi,

Around August this year, after some firmware update, my phone started to reboot spontaneously one or more times per day. I didn't find any particular circumstances for this behavior -- it may happen when I'm typing a message, scrolling Instagram or just laid on a table... The most problem is that it can reboot at night time (while charging) so after reboot, the alarm clock I've set at the evening doesn't work %()

Any ideas how to fix this really annoying bug?

Thanks.

[HTC U12+ Questions & Answers] mawoods75:
I have the Spigen crystal clear and I get ghost presses all the time. Kinda sucks... Buttons worked fine for me out of the box until the software updates started. Now I have ghost presses at least once every other day, sometimes the power button stops responding at all until a soft key is pressed, and sometimes touching the corners or back of the phone gives a ghost press... I've even had a couple of absolutely true ghost presses... Phone on its own not even being touched and I see the screen come alive and the volume move all the way up.

Even without a case, the occasional ghost press happens... Just not as frequently. I'm starting to understand all the early reviews and frustration. For me, it seems like the buttons are actually getting worse with each software update.

I hate it because I love the phone otherwise.

3 months back i hv flashed fastboot rom successfully. but now i stuck with different problems with no solution

1) mobile is dead, when i hold power button mobile screen blink for a second and off again

2)when mob is dead i cant go in developer option and do all that stuff

3)in fastboot mode when i type command "fastboot oem unlock" it shows error

4)when bootloader is locked i cant flash fastboot rom through mi flashtool

this all happen because of choosing wrong patched_boot file at the time of installing magisk manager.

cmd cammand only recognize my device but cant unlock. i find only one solution that is test point method. before i proceed to that need suggestion from u gye's should i go for testpoint or to service center coz mobile is still under warranty.
[Xiaomi Mi A1 Questions & Answers] sipollo:
You can flash stock ROM in edl mode with locked bootloader.

Put phone in fastboot mode and type "fastboot oem edl".

You should be able to flash stock ROM with Miflash. If your device is not recognised update your drivers. Google for qualcomm qloader drivers.

Next time before flashing a modified boot.img try to only boot it and see if it works.

Just got a brand new 2017 Shield. Got in to fast boot using "adb reboot bootloader" as I don't have a game controller and I was unable to get a usb keyboard or any other controller to work. Booted to latest TWRP and installed SuperSU. Now it doesn't boot. I'm just getting a bunch of warnings and errors regarding being unlocked and the system being modified. Then, I just get a black screen. Did I just screw up? Is there new update that I installed with DM verity enabled and this is causing it to stop booting?

Either way, it does not boot far enough for me to get in via ADB and I can't get back in to fastboot. Any other things I can try to get into fastboot? Assuming I can, what's the latest image I will need to reflash back to stock?

Any assistance/guidance appreciated. Thanks. :fingers-crossed:

Update: I was able to find a KB that works to get in to fastboot mode. So that's working. Is the latest development image from NVidia going to work for me?

Update2: So I just went for it since I got inpatient waiting for responses. Back up and running after flashing the latest developer image. Now to get SuperSU or Magisk working?

Final Update: It looks like I used a slightly older SuperSU (2.79) installer which I'm guessing broke DM verity (or something worse). After installing TWRP (permanently), I sideloaded the new SuperSU (2.82 SR3) zip and everything worked just peachy.
