No service on my MT4G. PLEASE HELP!

My MT4G is having a problem getting service. I get no bars and it keeps saying no service. I tried rebooting and even putting a new rom on it but nothing changes. It still says no service. Nothing is wrong with my sim card because I tried using it with my old phone and it worked. So I know it has something to do with my MT4G. Please help. I don't know what to do.

Restore it to stock and return it for repair or replacement.

Is that the only option that I have?

Well you could flash some more ROMs to see if it'll work. It usually takes about 15 minutes [at the longest] for me for me to get service.

you should just get a whole new sim replacement first to try it out just in case

[Q] LG repair costs

My phone is bootlooping and I can't access recovery. I can't restore the phone's stock software because I edited build.prop and it's not showing up as a Verizon phone. I decided to bite the bullet and just pay LG to reset it. However, when I contacted them to do this they told me I need to mail the phone in and they will tell me how much it costs after their tech looks at it. I'm worried if I do this that they'll charge me an exorbitant amount to fix it... Does anyone have any idea how much they usually charge to do this?

Sending the phone off to LG should be your last resort. It sounds like you've not tried everything!

Send it in to warranty. As long as there's no physical damage Verizon isn't going to give a rats a$$

Well, in another thread a Sprint tech said that LG did not give them a method to flash the stock software if the model check failed. I assumed this was the case for Verizon as well. I'll call them tomorrow and ask, I may have misunderstood what he wrote. I can't seem to find his post now. I'll update this post after work tomorrow if they can recover the phone.
theoneofgod, what is it that you think I haven't tried yet? If you have a suggestion which would save me the trouble of sending this phone in I would be super happy. To recap, here's what I've tried:
1. Using hard keys to factory reset (on TWRP 2.6.3.1 so it actually factory resets instead of booting into recovery)
2. Hitting "adb reboot recovery" over and over as TWRP loads and performs factory reset (this worked for people on 2.6.3.1 on AT&T but doesn't seem to be working on my Verizon phone for some reason. I've tried it dozens of times and even wrote a batch file which spams "adb reboot recovery" many, many times faster than I could type it)
3. Flashing the .tot file through download mode (Model check fails)
4. Flashing the .kdz file through download mode (Hangs at either 4% or 10% and asks me to restart. Never gets past 10%)
5. Entering my IMEI into the LG update tool, letting it download the software for the phone, and letting it try to flash the software (it fails)

What was the reason for bootloop? i also change my model name to make camera app show pics in menu, but it didn't help, and i returned to stock build.prop. So whats your story? Its good to know what i should NOT do with the phone.

Yea a good idea if you share what you've done so readers can be aware of it. Goodluck to your G2 pal and we're sorry for you..

Np don't mind sharing, thanks for the sympathy this definitely sucks aha. I usually add in qemu.hw.mainkeys=1 to get rid of the software keys when I put a new ROM on. It worked the first time I did it on this phone, my best guess is that I mistyped something. I'm not 100% sure why this is making my phone not show up as a Verizon model during the model recovery check...someone more knowledgeable than me would have to explain that.
Melodycd, I think you should be fine doing that as long as you're careful. I was pretty careless and made a lot of mistakes to get in my position. As long as you don't do ALL of the following things you should be safe:
1. Not have the latest recovery
2. Not have USB debugging enabled
3. Mess up while editing a build.prop file so you bootloop

It doesn't matter what they can or can't do with the phone. They don't care what you did to it as long as it's not physically damaged or have water damage. Software issues can be fixed. If they couldn't flash new software they wouldn't have CLN devices to send out for warranty.
I've sent in several dozen phones that I left rooted (for legitimate defect concerns) and none were charged back. They don't need to know what happened to the phone when you call all they need to know is its not working and to send you out a device. They'll receive yours, flash it or send it back to LG to flash, then send it out to someone else as a warranty device.

Okay I'll send it in tomorrow. Thanks man, I was just worried that since the phone says "rooted" in download mode they would flip out about it. Appreciate the reassurance.

I'm just sharing my experience. Over the past 5 years I've been rooting and returning. I can't guarantee anything but i can tell you my experiences and what I've been told by vzw people I know.

I had my g2 repaired when it was rooted. My camera wasn't working atall would just show up black when i opened the app. I sent it in rooted w CWM recovery as i stupidly forgot to remove it. And i had a replacement within 5 days no questions asked.
Not sure if this is because i am in UK or not, but they didn't blink an eye.

Yep I was just worried because the Verizon phone explicitly states that it is rooted. Just to follow up for those who are on Verizon and are stuck bootlooping and with no way to flash the stock ROM, what 06stang said held true for me (so far). The Verizon rep on the phone couldn't help me (she said she needed me to put my SIM card in my G2 when I was calling her from my old phone) so I took it to a Verizon store. The dude checked it for physical damage, tried to turn it on, and when he saw it bootloop he put in an order to get me a replacement phone. I'll report back in a week or two after I send in my rooted phone and let people know what happens, it seems like they won't charge me as of right now though.

When I turn on the phone sometimes only the buttons light up

Verizon Galaxy S5 which I've had almost a year.
Sometimes when I turn on the screen, the screen flashes and then goes black. The buttons stay lit and I can enter the unlock pattern but not see anything.
Does anyone know if this could be a loose cable or ribbon inside the phone that needs to be tightened or might it be the screen itself? The weird thing is that when the screen does light up, it works perfectly.
If I knew which ribbon could be loose, I'd take the phone apart and tighten it. I'd hate to pay a fix-it shop for something I can do myself.

Warranty Replace
I spoke to a friend who used to work for Verizon and she reminded me that since the phone is less than a year old, I can go into the store and get it replaced under manufacturer's warranty. Yay me.
I will back up the phone's apps and data with titanium backup. Is there a different program that does not require root? I'm asking because I have rooted KitKat on the phone and might want to try going to Lollypop, but am not sure if there's root for that. I guess it's time to dive in, get my hands wet and see just how far one can get with rooting. Also, I will have to return the phone to unrooted status before going in. Such a pain.

Got replacement
I got a warranty replacement and have rooted android Lollypop on it. So happy.
I oden'd back to stock NCG and took all the OTA updates, did a factory reset and added a few apps.
It took the VZW employee less than 5 minutes to determine the phone was defective and in need of a replacement under warranty. The cool thing is that I didn't have to do any factory resets or anything else. The employee tried the test app on the phone and since the flicker is not something that can be tested for, sent me a new phone.

Bricked My 6P, But Not Sure Why/how.. Any help is appreciated

I'm pretty lost on this one and after hours of searching, have not the slightly clue how (or if) to fix it...if it can even be fixed.
Past few days I've noticed the phone randomly rebooting, some of the times it says my battery is 0% when it's almost full. Today I went to go wipe it and reflash Pure Nexus. While wiping and flashing it, it ended up in a boot loop. I've tried everything to get the phone back up and running. I've tried attempting to flash different ROMs, the stock images (tried T and Q), doing a hard reset, factory reset. Literally everything under the sun that I know to do or have looked up.
Right now the most my phone will do is turn on, shows the Google screen, the reboots and repeats. Sometimes when the phone is off, I have to hold the power button for a minute or 2 to get it to turn on. Still, can only get in the bootloader, but can't get it to boot further than that.
Any help is appreciated, I'm at a loss on this one....and phoneless. :crying:

Pretty weird, if nothing works you should flash stock images, lock bootloader and RMA.

I also tried to lock the bootloader and re-unlock it, with no luck. Called Google and they weren't any help, least outside of what I've already tried. I'll be calling Huawei tomorrow when they open.
As of now, it seems when I unplug my phone, it just turns off. I plug it back in, it goes into bootloop (without me hitting power button). Sort of wondering now if the battery just took a dump?

The phone started acting funny every since I tried to Android N. I'm going to attempt to try flashing N again, just for kicks.

I found a USB charger at work. While not a fast charging one, it was enough to allow my phone to boot up. Apparently there is something wrong with the battery some how. When it booted up, it showed I still have 48% of battery left so I took it off the charger. About 5min after booting it shut down again. Now that it's on the charger again, it'll boot back up and now shows 1% of battery.
I can't figure out for the life of me what the deal is. Looking like I'll need to lock the bootloader and RMA it back for warranty and get a properly operating phone. I'm curious how quick this will happen to get a working phone? I'm up for an upgrade through Sprint, think at this point it's best to go get a new phone to use in the meantime since I have no old phones to use in the meantime. If Huawei gets me a new phone within 14 days I can take the new one back and rock on with Nexus. Kind of sucks, but just my luck.

That's exactly what you should do. Most probably the battery is dead or malfunctioning. Charge it with that spare charger for a few hours, then restore stock and lock the bootloader. Finally, turn it up for RMA.
I never had a single out-of-the-box issue with any of my 5 Nexus devices. I hope the replacement that you receive will be up to the satisfaction.

Thanks for the confidence. I'll do just as suggested and return it.
I'm up for an upgrade, although I have to do online so I don't have to pay an extra $30/month for a phone I'll sell after getting my 6P back. I hate sprint not letting me do it in the store, such a PITA. If I do online I can just get the discount and sign a 2yr contract which is fine with me. Any idea if they will ship a new phone so I'm not without a phone for week(s)?

Sorry, but I never had any experience with an international carrier like Sprint, so can't say. Someone here would be able to answer this better than me. :highfive:

Thanks for the quick reply. I'll call Huawei here in a few and start the process and find out. Fingers crossed they will ship a new phone, even with a temp hold on the money while I send this broken one back. I'll post what I find out, just in case anyone else is curious and searching for the answer.

V20 VS995 Bootloop (no root, 1CA update)

Today on my way to work I was playing music through my bluetooth and the music stopped. I went to reset bluetooth and it took almost 3 mintues to turn off. When I went to turn it back on, it wouldn't. I powered off and reset the phone. After, it got stuck in a bootloop. LG logo for about 7-8 secs and restarts.
Before the bootloop, I was noticing a few weird things: A notification of USB Options was always up, was saying I was using my phone as a USB Power Supply. If I changed the options it would revert back to USB PwrSply. I noticed the battery life was getting a lot worse. Also, when plugged into Quick Charge it would not say "Quick Charging" anymore.
I can get into the Recovery menu, but all options revert to the bootloop.
I can get to the Download menu. After about a few seconds of sitting on the Download menu, it starts the LG logo bootloop.
I have not tried to flash another stock ROM. I have downloaded the LGUp program, Uppercut, LG Mobile Support Tool, and LG Mobile Driver. I also downloaded the previous 1BA firmware kdz file.
I believe I have the knowledge to reflash properly, but I do not want to make the phone worse or lose my data. Plus, I don't want to void the warranty.
TL;DR I have bootloop and want to save my data!
Any suggestions would be very much appreciated! Thank you!

Flashing won't help you, this is a hardware problem. You can try freezing then phone, seeing if it will boot, and then backing up your files a fast as you can. Alternatively, if that doesn't work, you can take a hair dryer and heat the phone up.
Either way, LG will definitely take care of it under warranty since those morons can't seem to make a decent heat sink that lasts. Every LG flagship phone since the G4 has had this problem. I am sure the V30 and G7 will be no different -- they just haven't been out long enough yet.

I was hoping that this wasn't the issue. I was hoping that it was from the 1CA update, because the other random problems seemed to have started when it updated. Should I at least try to reflash? Would reflashing to a stock/OEM ROM (the one i mentioned above) void the warranty?
Also, when I restarted the phone today, that was the first restart that I have done since the update. Not sure if that means anything, but maybe??? lol

No, flashing a KDZ does not void the warranty even by LGs terms.
In the US rooting your phone doesn't void the warranty either .. no matter what OEMs will have you believe.

Awesome! That's definitely good to know. Thanks.
I'm going to attempt to downgrade flash it. If it doesn't work, I'll contact LG. I dont really care about buying a new phone. My data on it is worth WAY more to me than the phone. (Guess I really should start backing up my stuff XD )
If you have any suggestions as to recovering my data, even if it kills the phone, I'm all ears!

Update: I attempted to flash or just access the phone as storage using many different ways. While I was browsing for new answers, I kept the phone connected to my computer and left it bootlooping. Eventually, the phone battery died and booted up properly. The battery was at 1%, but everything loaded just fine. I was able to recover all my data and save it to my PC.
Thinking that this was a soft-brick due to the phone actually fully booting, I was going to attempt to root and flash. I let the phone charge to 100%. When I reset the phone to implement the root, the phone got stuck in a BOOTLOOP AGAIN.
Any ideas in why this would happen? Does this mean it's a software based bug, or hardware?

I'm not sure to be honest, your situation seems strange

Was it hot and was your phone in the sun during your trip to work? Overheating can make weird things happen.

It wasn't hot at all, I had the A/C in my car on and it sets on a car mount that mounts to the air vent. It gets direct A/C. I didn't have it charging either.
All I did was connect my phone to Bluetooth, play a mix, and drive 15mins to work at 6am in the morning. It was still dark and cool out. The music stopped and I tried to reset bluetooth. It took forever to turn off and wouldnt turn back on. I reset phone and BOOTLOOP. ???
There is no damage to the phone physically. I don't think I've ever dropped it ever. It's gotten hot a couple times, but that was months and months ago.
I've never had a problem with this phone since I got it almost 2 years ago, since the 1CA update, I had a couple bugs, now this bootloop.
