I'm sure you have personal info like texts and apps in there so we only want to Android backup system.

Firstly try adb backup -system (doesn't work for me but I'm not rooted

Or if that doesn't work simply adb backup -all -system -f -backup

The file be saved on your PC as "backup" either in the root of the hard drive or in the ADB folder somewhere.

You need ADB installed. Use minimal ADB if you don't have it installed yet. And of course usb debugging needs to be enabled

It would be helpful to see if it really is the s8 twrp!

168mb seems really small for a backup . The system image should be much bigger. I looked at my v30 lgup dump and my system is 6 gigs, so 168 seems VERY small. Do you have apps, pics and stuff like that on your phone? Or is it like right out of the box with nothing on it yet?

Can anyone else help out here with the backup ? I've only done it once and didn't really pay attention.

Edit: the -all backup switch makes a backup of everything including personal info. If you can't figure out how to do just the system, you can send the link to me in PM and I'll remove all personal info and repost it cleaned out. The kernel is all we need but it comes as a package deal thanks to lg?

[LG V30 Guides, News, & Discussion] ChazzMatt:
If it is, it would probably be the Snapdragon S8 TWRP for Hong Kong/mainland China, not the TWRP for Exynos variants. A lot of people don't know their Galaxy flagships -- with Snapdragon chipsets -- have simple OEM unlock bootloaders unlike those shipped to North America.

(And those Hong Kong/mainland China Snapdragon Galaxy S flagship phones have all the North America carrier bands, too. Quite the treasure trove.)

Would there being any benefit to flashing just the System from the h930? The h930 doesnt have the same RSA sig as the H932 but from what I read from Runningnak3d that the boot and system arent signed so we could possibly cross flash if we found a way

You guys are all close. That is an H930 with an H932 system image, or at least modified to look like an H932, but it is most definitely an H930.

[LG V30 Guides, News, & Discussion] ChazzMatt:
You're the expert, but to clarify...

You're saying this Chinese guy in China was sold a fake T-mobile H932? That it's a rooted H930 somehow gussied up to seem to be an H932?

Is the Galaxy S8 Snapdragon TWRP fake also? I'm asking because then that's a really esoteric fake. If you

read the instructions on how to install that TWRP on the Chinese Snapdragon Galaxy S8

, it's very similar to the ways (workarounds, etc) how you're trying to install TWRP on the H932.

Both Samsung and LG are very competitive South Korean OEMs who may have stolen code from each other. ;) It wouldn't be completely surprising if someone found some method that worked on one might work on another.

Is there any way it's really a bootloader unlocked H932 with portions of the H930 flashed over it -- perhaps to to make this Galaxy S8 TWRP flashing work?
[LG V30 Guides, News, & Discussion] runningnak3d:
Yep. That is exactly what I am saying.

He is someone trying to get people to buy these "H932s" but lo and behold, they don't have the 600Mhz band.

It was done on the V10. A lot of people bricked their phones because they thought they had one model, but had another.

Can we edit any fastboot utilities pulled from our phone? I yanked out our phones system. Looking through folder: systrace\catapult\devil\devil\android I came across the fastboot utilities test python file. Looking deeper into that there is the order of how things are flashed using the self.assertCalls. which contains one line that mentions root. The line goes as follows;

class FastbootUtilsEnableFastbootMode(FastbootUtilsTest)

def testEnableFastbootMode(self):

with self.assertsCalls(

self.call.fastboot._device.EnableRoot(),

self.call.fastboot._device.adb.Reboot(to_bootloader=True)

self.call.fastboot.WaitForFastbootMode()):

Cats and dogs living together, mass hysteria...

https://youtu.be/JmzuRXLzqKk

Sprint and Verizon phones being converted to US998 or vice versa. (US998 can have Verizon Oreo KDZ flashed, and it becomes a VS996. Or AS998.

H930DS, H930G flashed with H930 firmware becomes H930, even activating different radio bands.

Or you just flash PART of it, if you need part of it for some reason. Like root, TWRP. There would be no other reason to flash part of H930 over H932.

Because there's absolutely no reason to make an open market European H930 pretend to be a T-Mobile H932 IN CHINA. H930 is worth more. But there might be a reason to flash part of H930 system over a bootloader unlocked H932, to gain some sort of attribute the H930 has.

[LG V30 Guides, News, & Discussion] TheDannemand:
We've been down this path before, and each time [MENTION=3167089]runningnak3d[/MENTION] has posted warnings about it before somebody bricked their phones: H930 and H932 use different RSA certs to sign the firmware, so the H930 kdz either would not flash, or if it did, wouldn't boot. Most likely it would format the partitions, but fail to write anything to them.

That's where it's different from V20 which used the same cert for all models.

Is there something different about this new Modified LGup that everyone is using now?

Originally my idea was to unlock the bootloader on the 932 and flash another firmware or just bootloader from US998 or H930. But it didn't go well for those bold enough to try. I couldn't get it to work on my device, unfortunately.

If the modded LGup for v30 actually works now then maybe we can. I'm still doubtful it'll work, but I'm hoping.

To be honest, reading all this makes me feel like people have gotten sucked into desperate theories that have already been warned against and/or disproven over the last month or two. I wanna see this phone rooted as much as the next person, but flashing stuff for Galaxy phones or trying already failed experiments isn't the way to do it... lol. What we need is a fresh approach, a new clue, something that actually gets us closer.

Do we know if there's any chance of LG implementing Project Treble for the V30? I haven't really seen or heard anything on that either way, but I would guess they wouldn't do it, since they don't have to and they've turned to being more unfriendly towards development on this phone.

Galaxy S9 with the Exynos processor has been rooted. The Exynos doesn't have the security that the Snapdragon does.

-- Brian
[LG V30 Guides, News, & Discussion] ChazzMatt:
I don't see anything "desperate" about it. It's EXACTLY what is being tried already -- flashing PART of the another phone's files to the H932 to get root, TWRP. It's just not LAF or perhaps it's LAF + something else.

Something about the H930 gave this H932 the ability to root and have TWRP. Maybe it's something from already rooted H930. Who knows? Then paired with the bootloader unlocked H932, gives it root, or the ability to get root, or the ability to install TWRP.

Why the Galaxy S8 TWRP? It's probably not even be Exynos TWRP, but the Snapdragon S8 TWRP -- which exists and it used in China on the OEM bootloader unlocked Snapdragon S8 that region receives. Why not use LG Joan TWRP? Why use TWRP from ANOTHER seemingly completely different device? (Except it's another South Korean Android running Snapdragon 835, so maybe there's some similarities we don't know about.) If it was an H930, they would be running Joan TWP. But it's not. It's a an H932 with parts of open market H930 flashed over it to give it special powers.

The problem is these Asian cell phone guys do this all day long and only this. We have regular jobs.

We first saw this a couple of months ago with the "Canadian H933" V30+ -- which was a Unicorn sighting. There is NO H933 V30+, only V30. In retrospect it was the first public verified case of this cross flashing. Someone took a "bad" Sprint LG V30+ (a dime a dozen), and turned it into a Canadian H933. They've also done it with US998 (more realistic, as there are US998 V30+) and AS998 (for U.S. regional carriers).

We've also had US998 V39 turned into Verizon H966 by flashing Verizon Oreo KDZ over it. We've had H930DS turned into H930 by flashing Oreo KDA over it. This also affects radio bands -- for good or for bad.

In this case, in China, they either couldn't completely convert the H932 to H930 (since it still identifies as H932) or didn't bother.

On the flip side, I don't see how it's an H930 masquerading as an H932. That would be like a Porsche masquerading as a Volkswagen. In China, H930 is the REAL deal -- what's more valuable. Easily root, easily install TWRP. DONE. H932 is not as valuable. They couldn't care less about the useless LTE band 71. BUT if you could buy a cheap H932 and convert it into a rooted phone with TWRP, then you're essentially making the Volkswagen H932 as useful as the H930 Porsche.

We just need to figure out what they did.

No, there won't be Project Treble from LG for the V30. They aren't required to do it and it would be a lot of work for them while they're trying to get the delayed G7 out the door.
[LG V30 Guides, News, & Discussion] runningnak3d:
So, I heard you guys don't want root anymore....

I guess you wouldn't be interested in the MASSIVE breakthrough I just made, and the V30 laf has all the opcodes needed -- no COPY opcode required.

[LG V30 Guides, News, & Discussion] ChazzMatt:
Oh, it's clear Verizon is a control freak. I guess I know about this more than you. ;)

With the Moto Quark, when for U.S. models sold by carriers only the Verizon Droid Turbo XT1254 was bootloader locked and Verizon would not allow Motorola to give unlock codes to users. Getting an unlock code voided the warranty, so had nothing to do with returns.

Other carriers in the U.S. didn't care (like for the U.S. Moto Maxx XT1250), carriers in other countries didn't care.

Verizon demanded it be locked down to protect their PRECIOUS bloatware because they get money from other companies.

The XT1250 = XT1254, they were the EXACT same phone, with EXACT same FCC ID. The only difference was the Verizon locked down bootloader. Verizon called theirs the Droid Turbo, but it was the exact same phone as the U.S. Moto MAXX XT1250.

The U.S. Moto Maxx XT1250 was basically the "dev" version of the Droid Turbo, because it had easily unlocked bootloader (and root) and would run on Verizon with a Verizon SIM card.

I ordered two Quarks from carrier in Puerto Rico and and a third straight from Motorola in Mexico. Mine were easily unlocked and I voided the warranty.

Why did Verizon demans locked down bootloader and no other carrier did? Control freak.
