So, first I'll quickly detail how I upgraded. Coming from Blisspop, I ran Autorec for Lollipop (linked in OP), rebooted to recovery, wiped flashed the ZVG radios (linked in OP), flashed the rom, and it was good to go. No tot back to stock required for me (YMMV).

I did the exact same thing to my ls980 coming from Blisspop 2.3 and it just looped at the LG boot logo. Then I flashed the kernel to see if that would work and now I can't even get the lg flash tool to see my phone in download mode! I can't even flash back to stock! Before that I tried to restore my my twrp backups but none of them are working now. Kinda pissed, not blaming anybody. I just wish sometimes things weren't explained in such a bleak manner. The more specifications the better. In other words, depending on which version of Blisspop and what phone model you're using....this might now work for everybody.

Last I saw the lollipop auto-rec was named "ls980_best_version_omg_so_good"
If you didn't flash that version. You will be in a heap of trouble.
And the icon has a picture of a lollipop with "ARec" written in it.

I just uploaded a boot partitions upgrad/fix coming from ANY version of ROM or Firmware. for testing You must have a LGD panel (Not JDI) to use. See second post in UltraROM for details.

It's all good on my end. For some reason the laptop that I only use for flashing my phone to stock was set to the wrong com port. I flashed to stock, upgraded to ZVG, rooted, used AutoRec Lollipop, wiped everything except internal memory, flashed the rom, waited a little bit for the LG logo to disappear and everything has been smooth ever since. It's a nice, minimalistic, clean rom. Indeed worth the trouble, good work. One question? How can I get a menu button in the navigation bar in this rom? Is it there and I just can't find it?

Good job, man.

Is this expected or a bug?
Thanks

Hi guys. I see that someone writes here that WiFi tethering should work in this ROM but I don't even have WiFi tethering item in my settings. Should I enable it somehow? May be it is related to my network type (CDMA)? How can I have it working? Would be grateful for any advice.

Help
Sorry, I'm fairly new with rooting and putting roms on my device so I need some assistance if possible. I current have the Sprint LG G2 device currently running cloudy 3g 2.1 prior to the Lollipop update. I was wondering if someone can do a video or walk me through returning it to official so I can OTA update to Lollipop and then get the rom ultrapop 1.2. Sorry to bother everyone just a noob here trying to learn on how to become more efficient on changing and updating roms.
Thank you,
Jose

First question, did you put the phone to cloudy 3g 2.1? It did you buy it that way?
Which service provider or carrier are you on? Sprint or someone else?
These are important as stock will only allow sprint to work.

Will we have The Dorimanx kernel soon?
I've seen he wants to add it but hasn't yet. The Lollipop Dorimanx is out, but no new version with it. Will we see it anytime soon?

Also, can you bring back the original task manager into the ROM? I miss having the app built in. And I'm having problems with video playback when I record something.

[All working except call audio and BT] [Nougat] [MM and LP bootloader] Desolation ROM

Hello XDA, I have been working on an Aosp-ish nougat rom for our beloved trltetmo. It has nearly no features yet, since it's an AOSP ROM. I'm a Nexus dev, and just recently started working on the trltetmo because I bought one. I had a marshmallow rom and kernel(but tend not to release stuff to anyone to avoid drama and the eta requests).
Downloads: https://www.androidfilehost.com/?a=show&w=files&flid=111459
I have uploaded my work to GitHub: http://github.com/TrlteNougat
For now until I get my gpu back, you have to flash this kernel for MM bootloader support: https://www.androidfilehost.com/?fid=529152257862667083
Known issues:
- Camera is wonky. It's going to be difficult to fix
- The phone acts like it's a dual sim phone, no usability is sacrificed, it just shows two APN settings and the carrier on Dialer
Features:
None yet, it's AOSPish
What is being worked on:
Bluetooth
Call audio (mixer_path issues)

The kernel source is up: https://github.com/TrlteNougat/kernel_samsung_trlte/commits/n7.0

Manifest located here: https://github.com/TrlteNougat/manifest

Nice! Subscribed.

Test build
https://www.androidfilehost.com/?fid=24723757092306996

This one doesn't reboot randomly. Still has ril and Bluetooth errors. Sound doesn't work. Camera does.

I m not dev. But great to see work on 7 ...cheers to all devs...hoping for a stable one soon thx again

I'm keeping my eye on this thank you

Ril is now partially working. I can send and receive texts. Calls cause a soft reboot, but shouldn't be hard to fix. Still no data connection yet, but that'll be fixed soon enough. Wifi connects but doesn't access internet for some reason. I haven't looked into that any.

Because why not

improper bootloader and in some cases modem can cause Wi-Fi to behave similar to how you have described. I'm not a TMO user but I think there should be several versions newer than OK2
if you have any desire to return to 5.1.1 or keep the option open to do it in the future, you may want to steer clear of the newest 2 or so bootloaders as they may prohibit further downgrading. if TMO is anything like Sprint, anything PE2 and older should still permit downgrades. newer versions I have not tested or seen any info on the topic.

[QRCODE][/QRCODE]ok I did a quick check and you are in fact on a 5.1.1 modem. I don't know if you've updated your bootloader but I get the feeling you would know if you have or not lol
all TMO MM firmware is newer than the Sprint firmwares (PB5, PC1, PD1, PE1, PE2) that I know to not prohibit downgrades, so you're on your own there.
if you believe the test builds to be compatible with the Sprint model, I'd be happy to help test as time allows for it

910T can be downgradable to DOK2 but not below that (unless you use work around and flash 910T2 firmware, which will allow you to go to 4.4.4 BL , and still can come back to latest) but thats a different story, regardless of that , however , you can anytime switch among DOK2 to PE3 to PG2 in any order. I think android N for 910T should be tested on EPG2 and not on DOK2 , atleast should give it a try on EPG2. I think the dev @USA-RedDragon , already must have tried all bootloaders and basebands , i m just replying to above posts.

I tried EPE3 on mm but got too frustrated with the issues. So I've been weary to try it again. But you do have a point that I should try with newer bl/modem combos. I've got a mm rom compatible with epe3, so I might as well flash that. The Odin files are on my desktop staring me down

Side note, the logs point to something bring wrong wkth the code and not a bl/modem -> rom compatibility. But I could be wrong. Never hurts to try

to make it easier ,why dont you just flash EPG2 BL and CP using odin (as opposed to entire MM rom) .and see if it fixes any of the issues with current N build.

Eh. I have other devs at my disposal. Most don't use XDA, and I tend to not either, but this(like any major version bump on a Samsung) is a big endeavor, so I made the thread for people to jump in if they wanted

D852 losing Custom ROM support?

After leaving the G3 and later aquiring an older, kind of busted but still functional G3, I went ahead and got it rooted and ready for a custom ROM.
Seems like the D852 and other variants are definitely not seeing as much support as the D855. (Which is understandable of course seeing as it's the international model.) But I dont ever remember having almost no OMS / Layers options or other ROMs to flash.
Does anyone here know where I might dig up some D852 XenonHD, RR, TipsyOS, or any of those sorts of ROMs? All I see is Octo and AICP, among some modified stock ROMs, and a handful of older deprecated builds..

The d852 has never had as much support as the d855. There are several roms available; LineageOS, cleanrom (google for the google+ community as it is not on xda), beanstalk (part of the cleanrom google+ community), crdroid. Cleanrom supports substratum. I'm not too sure about the others.

Cool thanks for the info! As far as those ROMs go, have you tried the majority of them? I've only tried crdroid, and Fulmics ROM so far. Hope to test out a couple more.

I've tried cleanrom and lineage os. Cleamrom is pretty much stock AOSP with some minor features like advanced reboot menu. I'm running lineage right now and I like it. Lineage apparently has no theme engine yet.

Curious to know if Lineage OS works with Substratum for now before the theme engine comes back..

From some posts I've read substratum does work for some themes. It's the kind of thing you have to try and see if it works.

Just ao u know oct os does not officially support d852. But what you can do since most of these are based off cm. Plz do not share the hard work of these developers but i usually just download a d855 rom unzip it andtake the system dat file out of it. Then i download aicp and teplace the system dat with the one i extracted zip it back up. And flash away. Now i do this for personal use so i can test out all these good roms that these developers make.

Hah, doesn't the system.dat file contain almost all of the ROM? From my understanding, you're just flashing AICP with very little changes over and over. Also I'm not sharing their work, I was simply looking for D852 ROMs to improve my broken G3’s battery, but thanks for the post.

my Cell signal is messed up. I have bootloader unlocked phone that is US998. I installed the US99820e_02_0910.kdz from ChazzMatt and then in TWRP Aroma installered the BoomBox V30 from Whiskeyomega. do you know how to reinstall the modem/cellular parts only?
EDIT: I changed back to the KDZ rom/version instead of BoomBox. I guess the question still stands. How do we reinstall only the cell part of the US998 rom into the BoomBox rom?

You don't say what provider you are with. But whatever it is, on 20E you are fine? It's only when you install Boombox that you can't get a signal?
On most ROMs, you do not need to re-flash modem. But still many developers provide TWRP flashable versions of newer modems so you can update when those are released. I am not aware of any TWRP flashable modems for the V30 yet.

Yeah, I'm confused about that as well. If his phone is working fine on US998 20E, then why is it not on stock-based Boombox ROM?

Dam xda login deleted my whole message and sent me to the front page. Mean. I won't rewrite it but here are the highlights.
TMobile. It's been a week straight of reflashing. I think it's a level 8 error but I don't know what I would mess up on these simple instructions. The messaging apps and phone app crashes. after putting in the apn settings, I got data but very poor. I've recreated some of the main features like dual speaker and sound mixer from whiskyomega and set the dpi to 560 and uninstalled many system apps through titanium backup on this US998 ROM. I'm exhausted on going through LGs tutorial stuff over and over again. Yeah i know what my buttons do, NAVI ya pest. I would definitely love to just flash boombox ROM instead of going through the hassle of this. However right now I'm tired of trying. I'll just wait for stable pie ROMs to come out.
Thank you for reading my long winded story.

Question:
I'm quite jnterested in flashing this kernel
https://forum.xda-developers.com/lg-v30/development/kernel-lunar-kernels-lg-v30-t3804267
for stock ROM (h930). Unfortunately, I've been reading the thread (I think I'm just missibg a few pages in the middle), but there are some things I couldn't find.
1. What are the bugs for stable? In the OP of the threat, the bugs are marked "outdated" so I'm not sure if the issues still persist.
2. Treblelized? I keep seeing this but I don't know if this is necessary. I haven't repartitioned, and I was wondering if i will have to moving forward (for flashing ROMs, kernels, etc). I can't recall seeing this on the bootloader unlock thread so I never got around to doing it (based on experience, repartitioning is dangerous - one mistake and you run the risk of hard brick - so I might skip this if I don't need it).
Again, thank yiu for the thread and for the amswers! Apologies if the questions are noobish. My last phone was a G5 that can't be rooted so I am far from up-to-date on flashing and modding (never had to do that on my g3 and g4 lol). And i didn't want to ask general questions on dev threads...

Custom kernel questions should be asked in the kernel thread. You can ask here, but the best people to answer - - including the dev - - are there.
No, you don't need "Treble" or to vendor partition your drive. If that's something you want to tinker with later, feel free. We don't have official Treble support anyways. The Treble stuff is project @SGCMarkus is doing to replicate Treble in our phone. But all ROMs without Treble in the title do not need vendor partition ("Treble") to install. You just need TWRP.

I see. My apologies. I'm not used to asking on dev threads as it was frowned upon on past device subforums (unless you have a log for your issue, questions are for the Q&A threads - I really don't want to bother the devs with a lot of questions unless i can provide logs to help them out). I guess it's qyite different here (still in awe of how helpful everyone's been).
I'll finish readibg the whole thread and ask there if I still have questions. Again, thank you. And i apologize for having a lot of questions.
Edit;
I'll probably leave treble alone for now. I've had bad experiences with repartitioning (hard brick) since one wrong move and there's no going back. Lol.

Is LOS 18.0 "Pre Alpha or Alpha" suitable for daily use?
Haven't noticed exact description what works and what are the current bugs.....

Do you think most of the bugs will be cleared out by the end of the year? Also, which kdz should I use if I want band 71 support?

I don't know anything about the bugs, but for b71 2 of the roms have it; US OP Pie (no Q yet) and KR OP which is Korean Open (Q version available) has b71 also.
cheers

I was thinking it might be possible to grab the modem partition from sprint or unlocked pie and write them over before installing this ROM. Would that work, or would it be incompatible?

I'm not sure, have not tried that. I've read others suggesting the same thing but don't know if they've had success with it. I'd bet it wouldn't as there are so many threads, in various model phones, about which rom supports which bands. If that problem could be resolved by simply using the modem partition from a diff rom, it happening would almost certainly be common knowledge and many threads with various modem partitions available, but there aren't.

Ended up trying it and it prevents boot to system and recovery. I replaced all 4. modemst1,modemst2,modem_a,modem_b
I think we'll have to wait for them to make Q for v405qa unlocked.
I used v405ebw with lineage 18. VoLTE and VoWiFi aren't supported, which basically makes Mint Mobile unusable except for data.

I'd suggest another option, as 405qa Q arrival is ???, use the korean open 30e. That's what I have. One mod makes it quite workable; copy the US Open /OP partition (from Pie) and use it instead of the KR Open partition. Everything works, including vowifi and volte. And it does get b71. There's only 1 other small change needed to get vowifi to work.
It's very solid and haven't had any trouble with it at all. Something to consider.

I just found out that a great deal of work can be done with Cellular Support via the Qualcomm PDC tool.

Can you link the Korean open download? Also, what is the small change for VoWiFi?

Yes it's on this link. It's at the top of the list, the KR Open, 30e is the last one in the beginning section.
The other change is minor, have to enter the service menu with the dial code and it's one of the SVC (iirc) fields you have to enable vowifi. I can find it if you decide to do it.
There's a little 'trick' u need to do when cross flashing, to avoid the 'NT_Error' thing when u first boot up. It doesn't cause a problem, it's just annoying. Just after doing a partition DL of the rom, let it boot of course, to finish. Then shut it off, don't touch anything. Then use LG up and do a refurbish with same rom. No more nt-error code thing.
Also, even though the firmware page (above) doesn't indicate it, that rom does have b71. I have a screen shot of the phone using lte discovery connected to b71 on that rom. It's there.

I'm trying to boot TWRP. When I run
Code:
fastboot boot judypn_TWRP_bootable-metadata.img
it reads out this:
Code:
downloading 'boot.img'...
OKAY [ 0.942s]
booting...
FAILED (remote: unknown command)
finished. total time: 0.946s
This is after flashing the Korean Open version. I'm not sure what to do. I made sure USB Debugging was on and changed the driver to the official LGE one, but no luck.

I tried everything on google. Still no luck.

Hi, so we've hijacked this thread long enough, let's move this over to this thread which is kor open specific.
Sorry about the hijack xenius.

Thank you for your work, @xenius9 - спасибо большое. Using lineage-17.1-20201118-UNOFFICIAL-judypn on Sprint LM-V405UA for about a month without problems.

You should get fastboot working via 9008 guide (I suggest not to wipe lafs on both slots), then fastboot TWRP.

If you install this apk (only on los), it will allow you to switch to the other side and reboot recovery. It's hard coded (I changed the original file) to boot to recovery after you select the other slot. Did it for the exact situation you're experiencing.
cheers

Is it stable? Good for daily driver? Thanks!

Hello forum!
I have LG LM-V405QA and would like to have a ROM flashed that removes all Google everything. I have flashed ROMs in the past, but have already spent too much time researching with no results. I am in California, USA.
This is a serious inquiry. Please help.
Thank you.
