You need to tell us more...

Have you read the instructions?

Did you ever have TWRP installed and rooted?

Hello yes, I read them my device is currently running havoc os 2.4 I flashed a lineage os recovery to my device and to get twrp back I tried to flash it through flashify. I rebooted then now both download mode and recovery are gone. When I try to reflash twrp through fast boot I get errors. The phone still says it's oem unlocked and rooted.

Try "fastboot boot twrp.img" to temp. boot twrp and then flash twrp zip via temp. twrp

U.S. T-mobile H932 doesn't have the necessary fastboot flash commands to do that. That's why [MENTION=3167089]runningnak3d[/MENTION] had to create this alternate method to install TWRP and root the T-mobile H932.

Wow, you messed up flashing another recovery over TWRP.

But I'm confused why you don't have Download mode. You should either have Download mode or a 2nd copy of TWRP installed on your LAF partition.

But you should either have a 2nd copy of TWRP on your LAF partition or you should have Download mode on your LAF partition.

Updated modems

Finally rooted my TMobile V30, it wasn't hard at all. Just needed to follow all the steps carefully. The online part I was stuck on was enabling fastboot/ unlocking the bootloader. It seemed different than the instructions, a YouTuber called highonandroid explained how to do it. I did a hybrid method of both to get it unlocked.

I think it's important to add in the directions the place to download updated modems to have roms boot and get the fingerprint scanner working

I listened to these instructions:

"ChazzMatt:

No, you can forget about 20o.

However, you should flash 20r before 20s. You can probably flash them together in TWRP, back to back. THEN REFLASH MAGISK. "

https://xdaforums.com/lg-v30/development/stock-t-mobile-lg-v30-stock-collection-t3917560

I used the "FullStock" options in the link above.

The method was:

Flash FullStock.zip (r)

Flash Magisk

Flash no-verity-opt-encrypt

Flash rctd remover

Rebooted to recovery and did the same process again with (s)

Then rebooted into the stock rom

them to TWRP and installed a custom rom

And everything was working!

Not sure if this makes sense but yeah.

Thank you for your hard work.

Did you first roll back to 10D? ( Don't honestly remember off the top of my head what the version was)

Did you unlock the bootloader?

Can you please explain your steps ? If you explain exactly what you did, we can help you a bit better.

---------- Post added at 11:52 PM ---------- Previous post was at 11:51 PM ----------

Dude, in the post to gain root literally says to flash H933 LAF
[LG V30 Guides, News, & Discussion] mobileclick:
thats my big mistake didn"t go back to 10d was still on 20J when flash LAF everything went well after flash laf finish then reboot phone stuck in fastboot no download mode and will not power up normal
[LG V30 Guides, News, & Discussion] Josh McGrath:
It sounds like you lost download mode and also any recovery you might have had. Did you unlock the bootloader?

Try to fastboot unlock bootloader again and see what it does. That should do a kinda factory reset. You *may* get factory recovery back but it might boot up after a reset
[LG V30 Guides, News, & Discussion] ChazzMatt:
I hope you recover, but the very first step -- and I mean #1 -- says to make sure you are on 10D.

#4 and #5 is to flash the H933 LAF...

You can't skip around with stuff like these. Best to PRINT OUT the directions, read them a few times, and physically check off each item as you do it.
[LG V30 Guides, News, & Discussion] mobileclick:
Yes that’s where I go wrong ? I already try unlock boot loader again do reset and still the same if I could only go back to download mode i be ok iam trying my best to recover it else maybe have to replace this phone ...
[LG V30 Guides, News, & Discussion] Josh McGrath:
Try fastboot reboot recovery it's probably going to send you back to fastboot but worth a shot.

Look on the web, you can find guys who will flash it via octobox or jtag to 100pct stock.

Alternatively, call lg and have them fix it. I think it's like 75 bucks but it's cheaper than a new phone. Or buy a cracked screen unit and replace the main board
[LG V30 Guides, News, & Discussion] BROKEN1981:
Not to get this modded by going into the grey area, but if you replace the main board, don't you also have to edit the IMEI? If so this is where XDA would not be able to help. Even a user myself I would be stuck.

This guy did not follow the steps and would be in a worse position than I would be in.
[LG V30 Guides, News, & Discussion] Josh McGrath:
Honestly I'm not real sure, I figured the Imei is stored on the main board and would show as a different device altogether. I've never done it myself. Sending it to LG would be the best bet IMO

And yeah, you're right. Since 10d has the commands needed, it probably only was flashed enough to brick it.

---------- Post added at 03:28 AM ---------- Previous post was at 02:43 AM ----------

Also try calling your carrier and ask about warranty exchange. Obviously don't tell them what happened
[LG V30 Guides, News, & Discussion] TheDannemand:
After owning my H932 V30+ for 1.5 years, I finally joined your ranks and rooted it yesterday. I have no real need for root yet, and have been hanging on to my 2-year warranty. But I didn't want to risk Pie coming out (with ARB1) and not be rooted before. (Yes, I could wait till Pie arrives, but all it takes is one accidental system update and my path to root would be gone.)

Everything went exactly according to [MENTION=3167089]runningnak3d[/MENTION]'s guide. Thanks a lot buddy!

Even then, this was the most hair raising root I've done. That point when flashing the H933 laf, and LGUP looks like it continues flashing other partitions (which would toast my phone)... that sure got my blood pressure up. We can thank LG, Qualcomm and T-Mobile for making our lives so "interesting".

After completing, I clean flashed Oreo 20s, using [MENTION=9374982]weakNPCdotCom[/MENTION]'s FullStock zip. Thanks a lot for that too!

Carrier unlock survived the procedure. I ran T-Mobile's Device Unlock app again after booting 20s. It claimed device was locked, although it already seemed to connect to Red Pocket AT&T. Requesting Unlock anew was Approved, and it did its thing on next reboot.

Only problem I have is a certificate error on some https websites, both in Chrome and Edge. Not sure sure why that is. Should I have flashed some interim Oreo versions before going straight back to 20s (which I was on before)?

I also notice that LGUP still claims I'm on 10d (I flashed weakNPCdotCom's 20r StockLAF).

Would it have been better to use LGUP Partition DL to flash 20s KDZ (all partitions except recovery) to make sure firmware etc is flashed? But then it would wipe TWRP if I don't manage to stop it before rebooting system after flashing...

Anyways, that's a detail. Thanks again!

[LG V30 Guides, News, & Discussion] ChazzMatt:
BOOM!

Now that you are finally rooted on very recent firmware, some things to install/try out:

* Fully enable DTS 3D stereo (root needed)

On all recent V30 variant firmware (except Canada H933 for some reason), LG put in the same DTS framework as in the V35 and V40. But they haven't enabled it -- for reasons unknown. No matter, with root you can enable it. Various listening perspectives, like Wide, Front, Side. Side is mostly my favorite, but can be too intense as it places you right in the middle of the musicians on stage. Front is more like the front row. Wide is very subtle.

Also in that post is the LG DTS Equalizer -- or you can install it from here:

* LG DTS 3D Stereo Equalizer

Install. Reboot.

* LG V30 Lockscreen EXTRA Weather Animations Enabler

Stock LG Weather Animations that show on lockscreen in stock firmware are rain and snow, but LG designed others which are in the firmware but NOT enabled (clouds, sun, fog, etc).

Make TWRP backup first before doing any of this, of course. In case you don't like it.
[LG V30 Guides, News, & Discussion] TheDannemand:
Thanks a lot man!

I already tried the LG Equalizer before I rooted (on 20s) and it didn't work. I assumed it was a H932 quirk, but I didn't pursue it further. It was mostly because some users on head-fi were always asking about system-wide EQ. I might try it again now after enabling DTS.

I'll be honest though, I wouldn't use EQ or DTS myself. To me it's all about getting the music stream unmolested and bit-perfect to the DAC. So the project linked below is where I will mostly use my newfound root freedom :D

Avoiding Android Mixer/48Khz upsampling of 44.1/16 audio

I consider myself very lucky to have gotten a V30 of all phones (even luckier if it hadn't been an H932). It started out looking to be almost unrootable (except H930) with very little dev support. And since last fall all models have been rootable -- with a healthy dev community, even now when the phone is approaching its 2-years birthday.

We owe that to a lot of hard work by the devs and yourself and TexanMoe and others. And a bit of luck too, I mean that WTF :cyclops:
[LG V30 Guides, News, & Discussion] ChazzMatt:
Well, before root the DTS equalizer wouldn't have worked because DTS itself needs root to enable. Try the DTS, if you don't like it, just change the build prop back. Easy. Or restore TWRP backup.

You're welcome! Yeah, WTF was [MENTION=6158380]TxanMoe[/MENTION] and also [MENTION=3167089]runningnak3d[/MENTION] helping him recover his phone after he thought he bricked it. When the dust cleared that's when he saw his bootloader was unlocked and then recreate those steps... If [MENTION=3167089]runningnak3d[/MENTION] hadn't helped him, WTF would probably never have been "discovered".

Excellent app Advanced Power Menu, just like those in custom ROMs. Replaces stock power menu. If you don't like it, just uninstall it.

my device is T-moble H932 ,and I don't know if it is permanent unlocked ，will it lock （SIM）again when root？ thx！
[LG V30 Guides, News, & Discussion] Josh McGrath:
No.
[LG V30 Guides, News, & Discussion] TheDannemand:
Oh yes, I remember vividly. I followed every post on the V30 and LAF rooting scene since fall 2017. And WTF really is one of the most aptly named root procedures ever :D

And Brian's contributions to this community cannot be overstated, including with TexanMoe's rescue -- and that of others too. I'm glad you pointed out his role in that, not just in LAFsploit.

Thank you for that one too. I ended up using Recovery Reboot (your original suggestion) instead of NOXX Advanced Power Menu (your latest suggestion).

The main reason is that I use Silent Boot to avoid untimely noise interruptions from T-Mobile's jingle when I reboot, and NOXX prevented that from working. So I just use Recovery Reboot when I want to load TWRP, and the regular built-in Power Menu for everything else. Very simple.

Thanks again, man!

So there is no one click root for the H932

I have the T Mobil H932 and found Kingroot. No success, so there is no 1 click rooting program for this phone yet even though its been out for over 2 years.

If not I was going to get the one plus 7 pro anyways and prey its easier to root that one.

I need root so I can mirror android auto and have full control from the deck and not have use the phone.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Of course there are no 1-click rooting programs for modern phones. If there were, we wouldn't be writing up detailed instructions like in THIS thread or the WTF instructions thread.

Due to all the security developments, I haven't seen 1-click actually work since maybe 2014? At least on major brand flagship phones.

Can anyone confirm if this method still works coming from the latest update v20s ? Thanks again !
[LG V30 Guides, News, & Discussion] TheDannemand:
Yes, it's still working. I did it a few weeks ago, starting from 20s.

I FIRST rolled back to 10d (as specified in the instructions) and THEN unlocked my bootloader. I recalled someone mentioning that fastboot was inaccessible on recent Oreo versions. I didn't try it, but that's why I chose that sequence.

It takes a little while to prepare everything: Backup phone (of course), download KDZs, the 20s FullStock.ZIP and other files and verify MD5/SHA1. Create SD card. Create USB flash drive with FWUL and test it.

Once preparations were done, everything went according to [MENTION=3167089]runningnak3d[/MENTION]'s guide. Just be careful when you flash the H933 KDZ to ONLY flash laf. And don't freak out when it looks like LGUP is still flashing other partitions as well.

One thing surprised me: After running rooted about a week, I was wondering why my phone still seemed slower than before rooting (on same stock 20s ROM). I discovered that flashing rctd remover does not remove LG's SRTC Root Checker app (com.lge.srtc) which slows everything down and phones home to the mothership. Before rooting, I would always ADB uninstall SRTC (along with T-Mobile's tracking app com.tmobile.pr.adapt). I just assumed that rctd remover did that too, but it only removes the root checking service rctd. So I disabled SRTC with oandbackup (you can use Titanium Backup) and the phone is now as smooth as before.
[LG V30 Guides, News, & Discussion] djwuh:
You rock! Thank you for all the info!
[LG V30 Guides, News, & Discussion] BROKEN1981:
Yes! FIRST unlock the bootloader. That's the first thing that you should do.

---------- Post added at 03:38 AM ---------- Previous post was at 03:33 AM ----------

Very odd. I don't have any performance issues.

Perhaps it's there and I just don't notice it?

Anyways, I always tell people to unlock the bootloader first. People have a funny way of forgetting and then run into trouble. After I bricked on a updated zip, I got a new device and was able to unlock on newest firmware.
[LG V30 Guides, News, & Discussion] Josh McGrath:
You can actually turn off srtc and rctd in the hidden menu if I remember correctly . I have the 6t now so it's been a while.
[LG V30 Guides, News, & Discussion] TheDannemand:
LDB/MLT (yet another LG tracker) can be disabled in hidden menu. It's always been disabled by default on my phone, though. Can also just be ADB uninstalled.

I wasn't aware that SRTC could be disabled in the menu as well. Is that the one called LG RTC in there?

I'm not saying the phone is crawling because of it. But it's definitely smoother without. Particularly if you use Battery Saver, you'll notice it when scrolling in lists etc. And it's using cellular data too (although not much) so I assume it's telling mum if you've been a bad boy and rooted your phone.

Thank you for confirming that bootloader can still be unlocked on 20s. I don't remember where I saw that comment that it couldn't.

I've done every part leading up to booting into FWUL and I've downloaded 3 different versions persistent/forgetful 3.1 FWUL and 2019 nightly persistent FWUL. I still get a bunch of error codes in particular wait for network to be configured then it hangs and I get a cpu lockup bug. Into failed to start initialize Pacman database and sort mirrors.

Ending with soft lockups over and over.

I'm not sure what I'm doing wrong.
[LG V30 Guides, News, & Discussion] TheDannemand:
I used FWUL_v3.1_x86_64_forgetful. Remember to MD5 check it after download. I booted it from a USB2 port, on a PC with a wired LAN connection. I don't know if that made a difference, but I just wanted to rule out any compatibility issues caused by fancy USB3 or WiFi chips.
[LG V30 Guides, News, & Discussion] Chekeenan:
I don't have access to an ethernet cable. Do I really need internet access to boot into FWUL?
[LG V30 Guides, News, & Discussion] TheDannemand:
I don't think you need internet just to boot it. But the root procedure does use internet to pull the LAFsploit code from GitHub.

Of course it doesn't have to be Ethernet, as long as FWUL supports your WiFi. I just always approach these things very conservatively, trying to avoid anything that could be causing problems. That includes using mature devices with mature drivers when possible.

One Plus 7 Pro. Yes it lacks wireless charging (a feature I don't use), an SD card slot (I only have a 128gig card in my V30+ (so 256gig total), so with 256gig internal this isn't an issue), and an IP68 rating (both the V30 and G6 have IP68 ratings and I have never felt the need to dunk either in water). The *main* thing that matters to me is that it is developer friendly. Full fastboot. No jumping through hoops to get an unlock code, or finding someway to unlock the bootloader -- just full fastboot from the jump.

I would have gotten a One Plus 6t, but the screen was still 1080p. Now that they finally came into the 21st century -- esp. the 90hz refresh rate -- it is a phone I think I am going to enjoy. I will finally be able to do the kind of development work that I enjoy instead of fighting with LG.

[LG V30 Guides, News, & Discussion] ChazzMatt:
NO. The One Plus 7 Pro has

* no IP rating (which all major OEMS have),

* no Qi wireless charging (which even Apple has and Google finally added back),

* no microSD slot

* no headset jack

If you read [MENTION=3167089]runningnak3d[/MENTION]'s post, he says the OnePlus 7 Pro LACKS all those things. He's saying he wants it anyway. ;)

But for the 2019 "7 Pro", OnePlus did finally add 1440p -- only FIVE YEARS after all the major OEMs did. :rolleyes: Moto, LG, Samsung, Sony, HTC, etc have long had 1440p displays. My 2014 Moto Quark (i.e. Droid Turbo) had 1440p OLED. So that's one thing I can't make fun of OnePlus for anymore.

But I'll still make fun of them for all the other stuff they LACK. I remember when OnePlus even shipped

one phone without NFC

because they said their users wouldn't notice. (Whereas even mid-range phones had NFC then AND their previous phone had it.)

I have long derided OnePlus as a pretender, who doesn't give their users premium features real top tier flagships have, while lying about it ("Never Settle" bullcrap slogan.) But that's just my opinion.

That's cool I'll probably end up with the 7plus soon, I went with the 6t, against [MENTION=3250376]ChazzMatt[/MENTION] s advice haha

Overall it's a good phone, except the FP sensor is complete garbage. You can tell it was rushed out and the camera ..is "just ok" . The 7plus is the same. Lg cam runs circles around it, that and the finger print sensor. The only redeeming factor that keeps me from throwing it in the garbage disposal is the 8gb Ram as it's lag free. (Ok that and the being dev friendly, Including a recovery tool for 9008 QC mode)

Now that lg locked their stuff down, I'm done with them for good but I miss my v30 for sure.

Just FYI the 7plus is water resistant but they didn't want to pay for the ip68 cert- I don't blame them. Also, if using facial unlock, the stupid motorized cam pops out every single time ?
