Need help with LG G5 RS988 - LG G5 Questions & Answers

I'm stuck with this device so I just need to repair it with help.
This is the problem:
I have BRIGHTPOINT 10h and I can't get LTE like many have reported.
I can't unlock the bootloader, I went to LG developer site and entered everything and was denied saying my rs988 isn't supported.
I don't and can't get root.
I want to get non BRIGHTPOINT software to fix my LTE. How can I flash software 11a-d or 21a or 21b without a unlocked bootloader or root??
Am I stuck with 10h??

I have the same issue with Cricket Wireless on AT&T network. Mine stopped getting LTE signal since Android 7.0 update.

Only for the RS-988 which were not sold through carriers. I have an RS-988 that was originally sold by Bluegrass Cellular, and 11c is as far as it goes. We need the later versions in order to be able to boot into recovery, and you can't unlock the bootloader and root unless you can boot into recovery.
It really sucks, the whole reason I bought the "carrier-free" 988 instead of the Verizon 987 was that I figured it would be much easier to root and install custom ROMs on it. Now we're stuck on an outdated version even though there are several versions later would could be running.

That's completely NOT how this works. You flash this and you'll likely brick your phone.

So only a T-Mobile ROM is compatible with the H830? International ROM won't work?
I suppose as long as the KDZ is a GSM not CDMA,. I tried it already on HTC M9 jumped from T-Mobile RUU to At&t and then to international RUU with no bricking.

You have to be particularly careful with LG phones (and in general). There may be some other models and manufacturers where this could work.
But I think this is rarely the way to obtain sim unlock.
A lot of the times the phones are not identical between regions and flashing a different firmware will totally destroy the phone.
LG in particular doesn't even like you flashing an older firmware onto the phone and instituted an anti-rollback mechanism on some US model phones, where even flashing the correct model's older version would result in a total brick. Yes, you could actually brick your phone by flashing a kdz file, meant for your phone, on LG flashing software, that was just the version prior.

So, in general. We have to wait to unlock the bootloader, root, TWERP and flash custom ROMS into the LG G5 instead of trying to flash a stock KDZ?
These manufacturers are making it harder and harder, we are somehow loosing the flexibility that made us choose Android over IOS.

flash the t-mobile firmware to the verizon lg g5

Hi, could I flash the t-mobile firmware file or rom to the verizon lg g5? I switched to t-mobile, and am able to use the verizon phone, but lte drops to 3g for calls and lots of the time data shows up as hspa when I check the icon. If it can be done, please explain how. Thanks in advance.
No you can't flash the T Mobile firmware.
other firmwares beeing flashed on different lg g5's
So, there is no way to flash different firmwares on the verizon model, just other ones. Is this because the bootloader is locked? How can people flash a different region firmware on some of the models?
I to am curious on this, i have called LG and was told that the only difference between the T-Mobile and the Verizon LG G5, was software based, and that their was no hardware differences at all.
If that is true, why would we not be able to flash the T-Mobile rom onto our verizon phone?
DO NOT ATTEMPT THIS OR YOU WILL BRICK YOUR PHONE BEYOND ANY REPAIR. It has been said MANY times before, google it first

The hardware is essentially different... Has nothing to do with locked bootloader, u could still use LGUP to flash regardless but it would likely brick your phone. Drops to 3g because of the bands used, there may be a workaround but it's unlikely.

sprint lg v30+ for tmobile user.

Sorry about creating a thread but wanted to make sure I can flash Sprint LG v30+ to T-Mobile without issue. Tried to read a few threads but from my understanding Oreo had messed things up at one point.
Does it have to be unlocked through Sprint first?
Simple flash T-Mobile or international rom makes it usable?

No, doesn't have to be unlocked through Sprint first. And Oreo didn't mess up anything.
Some of the T-Mobile guys are complaining about T-mobile Oreo. I own five US998 and don't see anything they are complaining about. Must be a T-Mobile H932 issue.
You will convert LS998 V30+ to official carrier unlocked model US998 V30+ with Oreo, and run on T-Mobile. Converting to US998 carrier unlocks the phone and gives it fastboot flash commands.
You can stop there, or you can bootloader unlock, install TWRP and root the phone.
Whatever you do after that (Install ROMs or whatever) is your choice.
You will NOT flash T-Mobile firmware onto the phone or you will brick the phone.
Many T-Mobile users are running rooted US998 (original or converted) on T-Mobile.

Thank you for clearing that up for me.
My Sprint V30+ is sim unlocked. If I flash it to carrier unlocked phone and toss a TMobile sim in it, will I get access to VoLTE?
Right now when I toss a TMobile sim in it, calls drop to 2G/3G.

If flashed to US998 Oreo you will definitely get T-Mobile Wi-Fi calling.
T-Mobile users can answer specifically about T-Mobile VoLTE on US998.
But since you can temporarily drop down to HSPA for phone calls and still get data, it's not critical. I don't have VoLTE on my AT&T Prepaid plan and I don't care.

Working roms/kernels for the Verizon variant of this phone? VS996

I plan on rooting and unlocking the bootloader but was unsure of which roms were compatible for the VS996 variant of the phone since I need the phone to be working on Verizon bands. Anyone have any experience on this.
Stock root is about it unless you don't mind missing phone calls and texts. I've tried about 6 roms and none worked without having to make a call for connectivity for a few hours, it's a pain for us Verizon users. Stock root works like a champ if that helps.

Agreed, stock root is pretty good, so I didn't bother with others. I don't need Pie yet, and can wait for it to arrive... no biggie.
When you unlock the bootloader (if you using the wtf guide) then you should already be on the us998 variant which includes verizon bands. So pretty much every rom out there works with it. Not all of them do though...

Calls not working through Simple Mobile / T-Mobile network

I'm at my wit's end on this. Calls stopped working the other day due to 3G disablement as far as I can tell. AT&T model unlocked and using with Simple Mobile on T-Mobile network. Calls would just say "Calling" for a long time and then eventually disconnect. I could switch to GSM and make calls again, but slow data. Simple told me to get a new SIM and when trying to activate, it shows ineligible IMEI due to no Volte it seems.
I'm trying to get that fixed, but running into various issues.
LM-G850UM
I tried to crossflash (https://forum.xda-developers.com/t/tutorial-crossflash-bypass-opid-mismatched-error.4345963/)
I flashed G850QM30c_00_NAO_US_OP_0224.kdz but it didn't ask me to change the model, so it still shows LM-G850UM software G850UM30c. IMEI is the same.
Since this didn't get calls back or Volte, I tried updating the MBN (https://forum.xda-developers.com/t/...ther-qualcomm-powered-lg-devices-too.4343655/)
Data shows 4G. Calls don't even try to connect.
I don't know what to do next and don't have much time to try to figure it out. I like the G8X, so I'm hoping there's a way to save it.
Any thoughts from the experts?

Make a back up,and cross flash it with T-Mobile firmware.Problem solved.
Thanks Surge!
I crossflashed to general firmware. Where's the best place for the TMobile firmware? Just off their website? Will that lock the phone again, or will I still be able to use the Simple Mobile Service?

It shouldn't lock the device if it's already unlocked.You can also use G8 firmware as well.(same device)Look here,this should get you the firmware you need.

That's where I got my KDZ before. I used the one here: https://lg-firmwares.com/lg-lmg850qm-firmwares/ and used the 3/24/22 version for Android 11. When I flashed it with LG UP, it didn't ask me to change models, which I'm not sure if that's why it didn't trigger it to start working again.

Most are using the international firmware for the G8 and G8x models.Which is what the qm firmware is.If you're carrier is T-Mobile or any T-Mobile MVNO,I would solely use T-Mobile firmware.My G8x is AT&T branded and factory unlocked,and I tried using Tmobile service about 2 months ago and was having issues sending text messages.I could place and receive calls and get text but couldn't send them period.
Yeah, so my G8X is AT&T unlocked. AT&T didn't activate VOLTE on this model, so when T-Mobile shut down their 3G network, Simple Mobile calls won't work and the current IMEI shows it's not eligible (because of the model.) At least that's my understanding so far.
So for the G8, is this the firmware I should crossflash? https://lg-firmwares.com/lg-lmg820tm-firmwares/ or I could try the QM which may or may not work. Is that correct? Basically going to the 820 firmwares instead of the 850?

I would go with the T-Mobile firmware since you're on their network.It wouldn't make a difference with VoLTE enabled with an AT&T sim.Once you pull the sim,and swap it it defaults back and turns the IMS settings off until it receives the configuration from their servers.Yes,820 firmware.It at least has the higher android builds,and better security patches.Once you put T-Mobile firmware on the device it should all work regardless of IMEI.
Edit:Make a back-up.Don't forget to do that first!
OK Surge....you've been helpful and seem to know what you're doing. What did I mess up?
I followed the cross flash instructions. I flashed the 820QM firmware first, and System loaded but the touchscreen wouldn't respond. I could only use the hard phone buttons. Decided to go to what you recommended with 820TM and it wouldn't boot at all - black screen - but I could still get to QFIL and LGUP.
I reflashed 850QM and touchscreen works again and I'm back to where I started.
When I flashed 820s, It did ask me if I wanted to change model numbers this time and I said Yes. And it asked it said it was changing some partitions on the 820 loads.
I may have been working on this too late. I appreciate your help so far.

I think someone else encountered this once before,and it was caused by certain manufacturering dates of the device.Some models can use 820 firmware,and some can only use 850.Looks as if yours is kind of stuck with 850 firmware only.I think the AT&T version I have I could go either way it worked with no problems.I still have my G8x but never really used it.I bought it because it came with the dual screen attachement,and $125 I took it.Here's my Sprint copy if you want to give it a try.It's a LUNS copy minus LUNS 5 for IMEI information etc.I was in the same boat as you on certain features not working with AT&T at one point myself and had to crossflash the Sprint version of the device.With that being said,try this one from LG Fans first.If that doesn't work,try my LUNS Sprint copy and let me know which ones works the best.

So interesting news....I obviously didn't try making calls last night at 2AM, but apparently reflashing with the same exact 850QM software I used before seems to have fixed the issue. Maybe changing the model to 820 and then changing back to 850? Who knows? That's like the 3rd thing that happened with this process that I have no idea why it started working differently, but hey I'm happy and back up and rolling.
Thanks for all of your help, Surge! I was truly at wits end, and had already ordered a new phone, even though I'm happy with the G8X overall. Now I can return that and keep rolling with the G8X.
Thanks again, you were a huge help and its much appreciated!

Glad you got it working!I run in to a same similar issue with a Note 8 I have,and it being an international unlocked AT&T phone.No calls would work period,and swapped firmware over and over and finally started to give up and flashed the stock firmware back and it worked.It's something that hangs in Android with the changed IMS settings that are sent to the device.It's all odd at the moment with carriers,but nothing surprises me anymore..lol..
"G850QM30c_00_NAO_US_OP_0224.kdz" Is a BPT kdz and is not truly open even though it says, "NAO US OP".
I got the phone working by using "G850QM30b_00_NAO_US_OP_0902.kdz", the "real" open kdz. Everything worked fine after that.

Yes,the firehose will always work regardless of the Android version.Also from what I have read,yes the same procedures work for A12 for root and unlocking the bootloader.As always,backup your firmware before rooting and attempting to unlock the bootloader just in case something goes wrong!

QM versions are international unlocked versions of the firmware.My branded AT&T G8x had issues sending text messages with T-Mobile service I do remember.I crossflahed my variant with the QM version and it worked flawless after that.But,I do have a full backup copy of the AT&T firmware if I ever decide to put it back.
