[LG V30 Guides, News, & Discussion] Septfox:
For this reason, I was considering a v35. Unfortunately it's not receiving much love from developers because of LG's oblivious idiocy and the cost/risk of working around that, and there doesn't seem to be much in the way of verification that the AT&T model (cheapest/most common) has band71, so...eh...

-

RAM is definitely a bottleneck, since apps have to be yanked out of memory and their state stored when memory runs low, then that reversed when they're run again. Flash memory will probably never be as fast as main RAM, so I expect more RAM will always be better (within reason, there comes a point where keeping it all coherent eats too much idle power).

Android is getting pretty good at minimizing the unload/reload times, though.

After running a Droid 4 on Kit-Kat, Nougat and everything in-between on a piddly 1gb of fairly slow RAM and a slow eMMC...I'll always choose to get more RAM if any added cost is reasonable.

-

Anyway, as it turns out, all we've got here is a bog-standard H932 after all.

The most boring guess was the correct one :<

Still not a terrible price for an unscratched screen and unworn display, though.
[LG V30 Guides, News, & Discussion] TheDannemand:
Oh, too bad, this was was finally getting interesting :laugh:

So a H932SV to be exact (it was silver, right?)
[LG V30 Guides, News, & Discussion] BROKEN1981:
Not sure why you call it bloat..
[LG V30 Guides, News, & Discussion] ChazzMatt:
To be fair, he hasn't actually used the phone yet. He's going by what LG touted to make it seem V30S "ThinQ" (stupid name) was a new phone. Then within a couple months, every V30 became ThinQ. ;) It's just improved camera software.

No, I never use the AI part, to be honest. But I like the improved camera modes.
[LG V30 Guides, News, & Discussion] Septfox:
Specifically, yup. Just a standard run-of-the-mill TMO Cloud Silver model.

Unusually well cared for, by the sounds of things....in stark contrast to the huge number of others ranging from "what the hell did you do, leave it on a belt sander?" to "nearly destroyed" I've seen while shopping. Makes me think that there should be some sort of responsibility test required before being allowed a phone :rolleyes:

I call any gimmicky software I can't remove by normal means "bloat".

That's not to say I wouldn't at least give the features a chance to impress me, but it is what it is.
[LG V30 Guides, News, & Discussion] BROKEN1981:
I use the AI camera. It actually improves the picture. At least in my cases it does. Especially night shots.

no different than what Google does with their camera app.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Agreed. In fact one of the most common questions when people go to custom ROMs is "how do I get the stock LG camera back?" (You can't.)

And they are pining over the Oreo ThinQ camera (especially from the latter Oreo releases), not the Nougat camera. ;)
[LG V30 Guides, News, & Discussion] Septfox:
So the camera app's pretty good these days then? I recall that back towards release, it hobbled the image quality in a variety of ways...to the point where it probably hurt sales when reviews got around. Thus the google camera port and considerable work to make it fully functional on the v30.

My knowledge is edging in on two years old, I have some catching up to do :eek:

I'm used to using two apps for picatures (Moto camera for speed, OpenCamera for functionality), so it's not going to bother me too awful much if LGcam/Gcam now each have strengths/weaknesses.

(sorry for keeping off-topic)
[LG V30 Guides, News, & Discussion] BROKEN1981:
I would have been upset if LG did not add in the AI camera. We have the SD 835. So LG needed to take advantage of the capabilities it offers.

There is a reason the V20 can't get it.

XDA did an article on the snapdragon with built-in capabilities.

Lost download mode

HI! I was just trying to root my H932 and now it is not booting into the OS nor download mode after flashing the h933 laf
[LG V30 Guides, News, & Discussion] TheDannemand:
Did you downgrade to Nougat v10d first using LGUP Refurbish mode, and flashing all partitions?

Did you use the LGUP linked by runingnak3d in the opening post?

And are you sure you selected only the laf partition in LGUP when flashing the H933 KDZ?

If yes to all three (so you did everything correctly) then I am wondering if the fact that you had previously updated to Pie could have something to do with it.

All I can think of at this point is to try a Master Reset (button dance). Copied from the OP:

Power off your phone

Hold vol down + power.

When the LG logo appears, immediately release power (and ONLY power) and then immediately hold power again until you get the the factory reset screen.

You never let go of vol down until the factory reset screen appears. Once it appears, you can release both buttons.

Choose yes twice by using the vol down key and power to select.

If your stock recovery is working, then maybe this will allow the OS to boot. If so, you should still be on 10d (assuming you downgraded). From there you can accept an OTA. Alternatively you can search for the H93220h OTA update file (first update after 10d -- not sure if it's .up or .zip file) and install that with LGUP in FOTA mode. Either way should restore Download mode.

No guarantees, of course. If this doesn't work, you may have to ping Brian for help.

Edit: Oh, and your bootloader is unlocked, right?
[LG V30 Guides, News, & Discussion] googler01:
"if the fact that you had previously updated to Pie could have something to do with it."

I think maybe this is the problem, I did the steps correctly as I did when I rooted previously,

---------- Post added at 01:20 AM ---------- Previous post was at 01:15 AM ----------

I have tried all those steps, I have an unlocked bootloader and everything, it will not boot to recovery either, just stuck at the "LG V30" screen
[LG V30 Guides, News, & Discussion] TheDannemand:
Got it. Yes it sounded like you knew what you were doing, but I had to ask.

I've seen some reports from other models of boot problems after Pie, but I have no idea if it's the same. Check the other threads if they give clues. Of course [MENTION=3250376]ChazzMatt[/MENTION] would know :o

I really hope this isn't something in Pie that blocks the exploit, even after rolling back to 10d.
[LG V30 Guides, News, & Discussion] googler01:
OK I just got it back into download mode!!!

It seems that the microSD card which I had inside somehow was interfering with the boot process, or interfering with the phone's ability to see the H933 laf, I have no idea, I am flashing the whole 10d firmware currently, using Partition DL, and I will try to root once more!

Update 1: after flashing the 10d firmware using Partition DL the phone rebooted and repeatedly and faintly flashed the green android screen with the "no command" message, where I rebooted wby pressing and holding Vol- + Power and immediately rebooted to recovery and factory reset the device with the Vol- + Power method - it has now booted into the system

Update 2: Flashed the h933 KDZ in LGUP with the partition DL setting and only "laf" checked, resulted in the same screen stuck on boot logo
[LG V30 Guides, News, & Discussion] Josh McGrath:
Is your SD card formatted to fat16? Some people have luck with fat 32, but not many so it's just easier to format to a single fat 16 partition. My 200gb sd card was in a single 500mb fat 16 partition and once I did that, it worked fine.

Also it's easier to just cut/paste the instructions from the guide itself

Sorry if I missed some details I just wanted to possibly help and give my 2c.
[LG V30 Guides, News, & Discussion] TheDannemand:
Wow, I hope you're able to get it back a second time.

I don't know if that's the cause of your problem, but the guide says to flash 10d using LGUP Refurbish mode.

I have no more suggestions, but I'll be very interested to hear what you find out. Fingers crossed for you :)
[LG V30 Guides, News, & Discussion] googler01:
Yes I got it back up the second time, refurbish mode is the same, I have flashed 10d using refurbish and partition DL, still no luck booting to android using the H933 laf
[LG V30 Guides, News, & Discussion] TheDannemand:
Well glad you got it back. But I cannot help wondering if they found a way to patch that vulnerability. The vuln is in H933 laf, and lafsploit depends on us being able to cross-flash it to H932. If they somehow managed to block that ability after updating to Pie, that would really suck.

I'm waiting for approval of a 2nd year warranty claim, not currently rooted, and not going to try anything myself. But knowing I'll be getting a Pie phone back from LG, this is very relevant to me.

One more thought: Were you using the new Pie-compatible LGUP or the original one linked by runningnak3d in the opening post? I would definitely try the latter if you didn't already.
[LG V30 Guides, News, & Discussion] googler01:
Yes I was using the new Pie-compatible one, where you have to select the "SetDev.bat" file. However I am wondering if I should have selected the "SetUser.dat" before flashing the Nougat (After Pie downgrade)
[LG V30 Guides, News, & Discussion] TheDannemand:
What I am saying is I think you should try the original LGUP (linked by runningnak3d in the opening post) when you flash back to 10d AND when you flash the H933 laf.

We know that LG changed something in the new Pie-compatible LGUP, since the older LGUP versions don't work with Pie. So maybe they changed LGUP in ways that prevent older ROMs and older lafs from flashing properly. They know that we're using LGUP to roll back in order to root. So this would be a way for them to stop people from rolling back to old vulnerabilities, but without increasing ARB (which I guess they don't want to do with Pie still being somewhat unstable). A reasonable assumption.

Of course I don't know if using the original LGUP will make a difference, but I really think you should try that. That's why I mentioned it already in my first reply to you.

Edit: What I really hope they DIDN'T do is change Download Mode in Pie so that it won't overwrite a newer laf with an older one. Unfortunately it would be a sensible change from LG's perspective and a way to finally "beat" [MENTION=3167089]runningnak3d[/MENTION] and his lafsploit: Download Mode is compatible across versions, and such a change would block any phone from flashing an older (vulnerable) laf once it's been updated to Pie -- regardless of which LGUP version is used.

Again, I'll be very interested to hear if using the original LGUP (linked in the opening post) to flash 10d and H933 laf makes a difference for you. If that works for you, it would mean they DIDN'T make that change to Download Mode in Pie, and that the barndoor is still open for us to root. Fingers crossed :)
[LG V30 Guides, News, & Discussion] Septfox:
I would present another possibility to consider: "Don't ascribe to malice what can be plainly explained by incompetence"

My bet is they screwed something up in the new version, that breaks downgrading in some way. I understand that Pie changes up some things internally (see also: no TWRP decryption for v30 Pie yet), it's not outside the realm of possibility that an unattentive dev missed something when rigging Pie support.

As far as changing Download Mode...anything is possible, but it would be borderline malicious on LG's part to *apparently* let the flash go through and instead end up soft-bricking the phone, since the v30 is out of warranty now (...I'm assuming? I'm not sure when they stopped selling them); the unwitting user who didn't like their Pie upgrade and thought they could just revert would potentially be SOL.

Proper/safe handling would have it either transparently fail (appear to succeed, do nothing) or fail and throw an error, not do whatever it's doing to cause a no-boot condition. Again, I would assume incompetence rather than them caring enough about a two-year-old phone to try and sabotage it. Heck, from what I've seen, LG is more oblivious than anything when it comes to people unlocking and deving on their phones.

-

I've been following the last couple pages; my H932 is coming tomorrow and I'm actually not sure if it's on Oreo or Pie, so potential Pie issues may be relevant to me.

I agree as far as trying the linked LGUP, and don't understand why that wasn't the *first* thing tried. The process has been written out, refined, rewritten, dumbed down to "grandma levels", etc several times now. There's a reason that certain things are hosted directly here and a custom FWUL environment is on offer: they've all been tested half to death and are known to work together as long as the specific tools are used and the directions are followed.
[LG V30 Guides, News, & Discussion] TheDannemand:
Well IF they had made such a change in Download Mode (and I agree it's a big if) it wouldn't normally have any negative effect, and certainly not a deliberately malicious one: I am ONLY suggesting that it would prevent overwriting a newer laf with an older one, not affect any other partitions. LG clearly wants to allow phones to be downgraded from Pie to Oreo, or they would have incremented ARB. Download Mode generally works across all OS versions. So an updated Download Mode that comes with Pie would simply be left in place when the rest of the phone is downgraded to Oreo. LGUP wouldn't even have to know about it if it's just Download Mode ignoring attempts to overwrite a newer laf with an older one. And that newer Download Mode would then also be the one that "protects you" from writing an incompatible laf, such as one from a different model.

To me it makes sense: It would still allow safe rolling back of the OS, it would protect users from old vulnerabilities and accidental cross flashing, and it wouldn't harm anybody -- except us who WANT to flash a vulnerable older laf from a different model.

But despite my making this case, I still agree with you that the most likely explanation is much simpler: That the original LGUP must be used in order for this procedure to work. I certainly hope so and look forward to any reports about it :)

So I found an old photo I took with AI cam. It's backed up to Google photos at reduced quality. So judge for yourself.
[LG V30 Guides, News, & Discussion] googler01:
OK gonna try that
[LG V30 Guides, News, & Discussion] TheDannemand:
Any news? Did you try with the older LGUP?

I'm curious because I haven't seen anybody yet report successfully rooting with lafsploit after downgrading from Pie.

I'm wondering if two steps might be necessary: (1) First roll back to Oreo 20s using the new LGUP (Refurbish) followed by Master Reset (button dance). (2) Then roll back to Nougat 10d using the original LGUP (also Refurbish) and the remaining lafsploit steps.

Again, I would try it myself, but am keeping my H932 unrooted while waiting for LG to approve a warranty claim.

Auto Reboot at end of laf procedure

Thanks for your reply. I see I wasn't to clear on the exact problem. I did indeed, "Simply lift your finger off power and back onto it"...

This exert from the procedure:

"You must use the key combination to immediately boot to TWRP:

Power off your phone

Hold vol down + power.

When the LG logo appears, immediately release power (and ONLY power) and then immediately hold power again until you get the the factory reset screen.

You never let go of vol down until the factory reset screen appears. Once it appears, you can release both buttons.

(At this point is where it reboots. As soon as I let go of the buttons. I never get the opportunity to "Choose yes twice..."

Choose yes twice by using the vol down key and power to select, and you will be in TWRP.

[LG V30 Guides, News, & Discussion] mrjackspade:
Just stumbled across this thread earlier today and signed up to post this.

Hopefully this helps someone.

When using the LGUP linked in the original post, I was UNABLE to flash back to 10. Complained about the wrong DLL.

I looked up another guide and ended up with the new LGUP that allowed me to roll back, but had the same issue where it locked on the V30 screen when I tried to flash the LAF.

After using the new LGUP to roll back to 10 with refurbish, I tried using the LGUP linked in the OP, and it actually flashed the LAF this time as the guide requires.

It looks like the new LGUP might be required to roll back from PIE (for some people?) but then the one linked in this thread is required to continue past that point.

So far everything is working, but thats not saying much since I havent completed the steps yet. It did get past this issue though as far as I can tell. Would have saved me about 5 hours had I known all of this before hand
[LG V30 Guides, News, & Discussion] TheDannemand:
Thank you for sharing that!

So you rolled back in one step from Pie to Nougat 10d using the new LGUP, then switched to the old LGUP to flash H933 laf and complete the lafsploit guide. Correct?

Good luck with the remaining steps!

[MENTION=3167089]runningnak3d[/MENTION]: With this report confirming [MENTION=7458309]googler01[/MENTION], I think this bears mention in the opening post, as more people will be coming from Pie to root.
[LG V30 Guides, News, & Discussion] mrjackspade:
Correct. I've got everything finalized now.

I wasn't able to get root, as far as I can tell. I did flash all the packages listed in the order they were required. I used the latest (stable) version of each as found on each download page. It's been quite a long time since I've done anything like this so that might be on me. I was able to get TWRP on Recovery as well as Download as suggested by the guide.

Personally, I was using this guide specifically to get TWRP installed so I could install a custom ROM, so I didn't bother hunting down the root issue. I was able to flash TWRP to the Download by using the TWRP installed in Recovery.

Now that I have the Custom Rom installed, everything appears to be working great. For my use, I would consider this a great success. Glad this guide was here to help and glad I was able to offer a bit of information in return.
[LG V30 Guides, News, & Discussion] TheDannemand:
Great, well done getting TWRP onto the phone!

Not sure why you weren't able to install Magisk, but as you say, not important if you don't intend to stay on stock anyway. However, DO make sure you flash the latest Stock Oreo TWRP flashable zip before any custom ROMs. It's not part of the guide, but mentioned many times in the thread.

Which other guide did you follow originally? This is the official guide written by the genius who developed lafsploit, and I am not aware of any other way to root H932. If somebody just copied it, they should have clearly credited and linked this guide.

Anyways, congrats. And thanks again for confirming about the LGUP versions :)
[LG V30 Guides, News, & Discussion] mrjackspade:
The TWRP I ended up using is "Oreo 3.2.3-7 TWRP, the one you should use" linked in the first post.

The other guide I used was just for flashing for rom prep, found here

https://www.the***********.com/inst...hing-Android-Pie-KDZ-Firmware-using-LGUP-Tool

Specifically, just this section here

(For Method 1 only) You must install the patched LGUP tool with support for developer mode on your PC. To do so, follow the list of steps below:

Download the ‘LGUP_DualMode.zip‘ file on your PC.

Extract the zip file to a suitable location.

Run the ‘LGUP_Store_Frame_Ver_1_14_3.msi’ executable file and install LGUP tool on your PC.

Once installed, go to the extracted folder, right-click on ‘SetDev.bat’ file.

Select ‘Run as administrator’ to set the LGUP tool to Developer Mode.

Now, when you’re asked to launch the LGUP tool in the instructions below, simply launch it using the desktop shortcut.​
[LG V30 Guides, News, & Discussion] Septfox:
Do you recall any error when flashing Magisk? It does occasionally just fail to patch for some reason, iirc.

Getting TWRP settled in "permanently" was the biggest thing....root is comparatively minor. Good work running the course and verifying that with a slight change in methodology, the H932 is still good to go :good:

Also nice to know that neither LG nor T-Mobile are going out of their way to plug up this (lets face it extremely difficult to use and not practical to exploit remotely) hole. Or at least, if they are, it doesn't appear they're doing a very good job of it.
[LG V30 Guides, News, & Discussion] TheDannemand:
Well put! :good:
[LG V30 Guides, News, & Discussion] mrjackspade:
No errors. I tried twice just to make sure I didn't miss anything. Everything appeared successful, just got insufficient permissions when I tried to do anything that required root outside of twrp.

Just to be clear though, I might have missed something really obvious once I was booted. I haven't actually rooted Android since... Gingerbread? It looks like a lot has changed since back then. All I did to test root was drop into shell and attempt to escalate privledges and execute the command. What with all the new root hiding and stuff I wouldn't be surprised if someone who's been more active with this sort of thing recently comes along and says it works fine and that I was just missing some super obvious step that didn't even need to be explicitly stated in the guide :laugh:
[LG V30 Guides, News, & Discussion] Septfox:
A lot has changed for the worse. Google has been on a quiet, slow-burning crusade for a while now, progressively making attaining and keeping root (among other things...ask some devs about "features" slated for Q in particular if you want to trigger them) more and more of a pain in the ass, in the name of "security" and because "users might break things".

They're not totally wrong, of course; the average user doesn't need root and shouldn't be able to flip an easy-to-find switch that grants it if a bad actor asks them to --- but they're also being a nuisance to people who know what they're doing and know what they want.

Anyway. That all aside, functionality should be similar to what you'd expect. Elevating in a terminal emulator/shell would be my quick-test go-to as well, and ought to be fine...unless Magisk handles things differently than the standard "ask for confirmation, grant SU if user taps Ok".

Dunno, I'm used to doing things in RR and before that, other ROMs+SuperSU; no experience with Magisk yet (the new-to-me H932 I bought is currently tied up trying to be returned due to scratches all over its "mint, unscratched" screen).
