Alright. I need some advice one last time, I swear... after this I'm not going to try to do anything.

Phone worked quite well for 2 days. I was enjoying this rom quite a bit. I decided to change the DPI down to 560. I saw that some others in this thread had done so quite easily... so I used this app to change it. Made the change to 560, granted supersu permission and rebooted. Only problem is that... the phone has yet to turn back on. At the moment the only thing I can get it to do is give me a screen that shows a large white empty battery with a cable leading up to it and a hazard exclamation mark in the bottom right when I am trying to put it in download mode. I have tried on multiple computers to restore back to stock following these directions. The best that happens is my computer recognizes an unrecognized device. No luck.

I would love to change the buildprop back or anything, but not even adb recognizes the device.

Otherwise, nothing. I can't get into recovery. I can't get the phone to start at all. All black screen. I can't get any reaction out of it. Any advice would be helpful, I'm on hour two of this. I realize that this is most likely not a problem with the rom, but wanted to see if anyone else had an issue and has advice/let anyone else who's thinking of changing the DPI and shared my troubles reconsider.

Thanks again!

The empty the battery logo is because the phone is dead try charging it for like 30 mins. Also it seems that app you used is 3 years old so it does not support lollipop or even kitkat. After charging it try get it into recovery and restore a backup. If you don't have a backup try wiping your data and cache.
[Sprint LG G3] bdpope88:
Thanks for the reply!

That emblem only shows up when the battery is removed and I'm trying to put the phone in download mode. So it makes sense. Any other ideas? The battery that I'm using is about 80% full. I still can't find a way to recovery mode.

What other information can I provide to help you out?
[Sprint LG G3] 1619415:
Well when your in download mode it does not take any commands can you get the lg powered by android screen? Or just nothing happens? If nothing at all happenes it is most likly bricked. If it boots to the lg screen it is most likly soft bricked.

Bricked- Phone is dead and very very hard to fix if there is a fix

Soft Brick- No OS so you have to reinstall a rom could also be, because of apps.
[Sprint LG G3] bdpope88:
No screen. For anything (other than described).

This is exactly what I was afraid of, but my phone has always been odd. This dead battery screen has always shown up in download mode... even when my phone worked, I've never had the firmware update screen. Which has always been weird to me.

However, the only time my phone shows anything is with the dead battery screen. During such it will show up as an unrecognized device when attached to a computer, again... it's always done this. I was just curious if there was something else or a suggestion that someone more experienced then myself might have.
[Sprint LG G3] 1619415:
No that I read it, it sounds like there maybe a very slim chance of getting your device to work. If you mange to get some drivers for the unreconized device driver you maybe able to send adb and fastboot commands. I found this one tool (will limk below) that is call cydia impactor I found in one of rootjunky's toolkit files. I used this one function that was able to make drivers for my sony smartwatch 3 and phone. I will link for the direct download make sure to extract the zip. Inside of the zip you will find another zip called "Impactor_0.9.14.zip" make sure to extract it to it's own folder. If you want you can delete the first folder juat save the impactor folder. Then run the program called "Impactor" can connect your phone to the computer and click on the tab called "USB" then click the button called "Driver Scan". Follow any on screen instructions. It should now generate a driver for your phone if all went well and it will be reconized. Then you should be able to run adb reboot recovery or fastboot reboot-bootloader. The fact that your computer is even seeing the phone tells me that it has so hope of being fixed because your computer see's it. Your device might be in a bootloop of some sort. You may just have no os installed and it may have just glitched.

i changed my dpi once and it bootlooped on me. i was lucky enough to get into recovery and then i restored the data partition from an older nandroid.

i agree with 16. it does sound like the drivers may not be loaded up properly if your computer recognizes a device. have you tried the official lg drivers?
[Sprint LG G3] 1619415:
What system are you guys running?
[Sprint LG G3] bdpope88:
Well, I've found out that for whatever reason... on my phone I have to take out the battery for a period of ~5-10 mins on any change DPI, system rom update, anything. Otherwise, my phone will not turn on. So if someone else find this, give it a try.

I got the XT1042 working On T-Mobile and At&t but the signal that I get for AT&T is so weak that it can barely be used. Can I flash the modem from the XT1045 to the XT1042 and would it help?
[Moto G Q&A, Help & Troubleshooting] dblackburn965:
How?

How did you get it to work on T-mobile and At&t? I accidentally bought an xt1042 motherboard and have been trying to do the same thing with no luck. I did flash the at&t stock image from an xt1045 as part of my attempt, and that is what the phone is on now and it seems to be working fine. At one point the phone was being recognized as an xt1045 when connected to the computer, but I don't remember what made it do that.
[Moto G Q&A, Help & Troubleshooting] Abu Siona:
I used the QUALCOMM BAND UNLOCKER guide here on XDA to unlock the GSM bands and then set the phone to RUIM Only using DFS. This is the band reference that worked for me the best: 562950069289863. If I unlocked too many bands the phone did not get a signal. Since we can get the diag port to show up by booting into BP Tools mode, most of the guide is not needed. Only the QPST and RV_NV_Manager.exe part to read/write the bands after getting the reference number from mzTool_1.2.1a.exe.

I hope this helps.

Oh and the SPL/MSL was 000000 for this model.
[Moto G Q&A, Help & Troubleshooting] dblackburn965:
I've tried flashing different basebands from the xt1045. It never shows a change in the about phone. On a whim I flashed a radio from the xt1032 I think. The difference here was that it was a flashable zip. After trying that the baseband did change, but it just said unknown. It didn't work, but it's better than it not changing at all I think we might need someone with an actual xt1045 to make a flashable zip of the modem for us. That MIGHT work.

---------- Post added at 06:38 PM ---------- Previous post was at 05:50 PM ----------

Mine is now working completely. Or at least it seems to be. I have 4g LTE with an at&t sim card, and I've verified calls and texting. My device is recognized as an xt1045 when plugged into the computer, and I'm running a rooted at&t rom. I used your settings for the band unlock and flashed the at&t stock rom. Pretty cool haha

Has anyone tried it on XT 1045 to unlock European LTE bands?
[Moto G Q&A, Help & Troubleshooting] Abu Siona:
When I unlocked the European bands the phone would not get a signal on US bands. I am not sure what caused this. The only way to know if it will work is to get one in Europe and test it.
[Moto G Q&A, Help & Troubleshooting] qwert940:
I am currently at Europe and I would like to do the test but can I roll back the operation if something goes wrong? For example phone will not get signal on US and EU bands for some reason?
[Moto G Q&A, Help & Troubleshooting] Abu Siona:
I was able to roll back by putting the default bands back into the NV item.

So before you write the new bands to your NV take note of the default bands that are there and if you do not get a signal then write the default bands back to your NV.

I have done this on several different phone models and after putting the defaults back, the phone worked just as it did before any changes were made.

just be sure not to change anything else. Only the bands in the NV item specified in the guide.
[Moto G Q&A, Help & Troubleshooting] afox27:
Ok I have written the band pref but how do I set it to ruim only in dfs this is the first time I've ever heard of dfs pls lol
[Moto G Q&A, Help & Troubleshooting] Abu Siona:
Once you have the phone connected to your PC with a diag port, open DFS and choose the port for your phone.

Send SPC as 000000 (all zeros)

Cleck Read next to the Ruim Config, just to see what it is set to, then change it to RUIM Only and click write.

I also found that you can get a signal lock on T-Mobile towers much better and faster if you flash the phone to RETUS_XT1045 4.4.3 or 4.4.4.

I did not need to set it to RUIM only after flashing this firmware to the phone. I only needed to set the bands.

if you have problems keeping a connection then try this band reference instead: 101188096.

This band is only for T-Mobile USA frequencies. I still can not get it to connect to AT&T USA towers.
[Moto G Q&A, Help & Troubleshooting] afox27:
Mine. Was set on ruim only already. I set the bands but nothing I'll try that firmware

When dialing *#*#7378423#*#* the phone does nothing. It seems that this also blocked as other commands.

There is another way to access the service menu?
[Moto G Q&A, Help & Troubleshooting] Abu Siona:
Not that I know of. I never used it myself. The mztool shows the bands that you are trying to activate and testing the phone with active sim cards shows me which networks it gets GSM, WCDMA and LTE on. Even if the bands get activated they may not work. It depends on what the phone is capable of right?
[Moto G Q&A, Help & Troubleshooting] afox27:
You can access that menu from a third party dailer app

Yes an the reason the base band didn't change when we flash the rekus xt1045 firmware is cause its missing system.IMG_sparsechunk.3 an ATM I'm picking up ATT signal on regular on the rektus firmware but unchanged nv items. Soon as I change them I get. No service. So i Just got to find the APN for T-Mobile so I will roam on ATT towers hopefully this will work.
[Moto G Q&A, Help & Troubleshooting] Abu Siona:
if I don't make any changes to the NV items, I get working LTE data with Tmobile but I can not make any calls using any GSM sim. Trying to place a call instantly ends the call. As soon as I make the NV changes All calls using T-Mobile work and I get no signal with AT&T.
[Moto G Q&A, Help & Troubleshooting] afox27:
Hmm wat about Verizon wireless wonder if it works. It tried to take over my phone earlier. An Verizon doesn't use sim cards so no APN stuff
[Moto G Q&A, Help & Troubleshooting] Abu Siona:
I connected to Verizon too. I do not have an active account with them so I could not call anyone but when I put a Verizon sim in the phone it showed verizon and dialing 411 and 611 connected me to the Verizon operator. Someone with an active verizon sim would have to test it to see if actual calls can be made.
[Moto G Q&A, Help & Troubleshooting] afox27:
Id say it will work fine on Verizon then. I have a feeling. U.s. cellular an Verizon. Are like ATT an T-Mobile,,,,,,,,,,,,ATT works on T-Mobile an T-Mobile works on ATT Verizon. Doesn't require sim cards. An. U.s cellular. Just uses them for there 4glte. Only
[Moto G Q&A, Help & Troubleshooting] afox27:
Ok this is weird. Revert back to the USC firmware. Flash the. Retus xt1045 system imgs only. An remove sim before booting. I get a carrier called T-cdma64 idk wat that is. An shows signal. But soon as go to the APN area. It vanishes
[Moto G Q&A, Help & Troubleshooting] doctor_evil:
I get similar results using a simple mobile sim which runs on t-mobile's network.

as soon as I try to make a call, instant disconnect, but it shows 3 bars of signal strength. I've tried it on two different XT-1042s one has a bad ESN for US Cellular, the other one was a phone I bought from a seller on ebay who didn't disclose that it was a XT-1042, only that it was a moto g lte and came with a free month of simple mobile service.... When I called the seller out on it being a XT-1042 and a CDMA phone not a GSM phone he tried to say it was my own fault, as I was trying to use it with cricket wireless not simple mobile. Just got done testing the sim and it doesn't work, instant disconnect when you try to call voicemail or make a call to any other number.

I'm probably going to have to go thru paypal to get a refund on this one, I'm more than a little pissed. If I had wanted another XT-1042 I would have specifically bought another one.
[Moto G Q&A, Help & Troubleshooting] Abu Siona:
Did you try to unlock either of the phones using the band unlock tutorial? I have an XT1042 in hand that I have been using for weeks now on t-mobile. LTE and calls work great. I have been using 101188096 for my bands reference on NV item 1877. Other than the bands and flashing the stock xt1045 retus, I did not change anything.
[Moto G Q&A, Help & Troubleshooting] doctor_evil:
I did try changing the bands. If I change it from 0 I can't get a signal at all, but if I leave it as 0 it shows as having 2 to 3 bars depending on where I am in my house. If I try to call the voicemail number which would initiate registering and setting up the sim it immediately disconnects.

The seller has offered to give me a partial refund which I agreed to take, as I don't want to have to file a dispute, so I guess I'll keep it to tinker with.

Question though, if the phone had a bad ESN would that prevent it from working using a simple mobile or t-mobile sim in this manner?

I ask because I have another XT-1042 that does have a bad ESN and it does the exact same thing after flashing it with the XT-1045 retail 4.4.4 firmware and radio. It really amazes me that anyone is able to use a XT-1042 for T-mobile like this. You would think that AT&T and AT&T MVNOs would also work if it did work with t-mobile since they run on the same GSM bands, (in the areas where they have refarmed their towers anyways) I know T-mobile uses the 1700 frequency in areas that haven't refarmed yet. I believe they are already done so for us here in Georgia but I may be wrong.
[Moto G Q&A, Help & Troubleshooting] Abu Siona:
As long as the ESN is not reported lost or stolen you should be able to use it on T-Mobile.
[Moto G Q&A, Help & Troubleshooting] doctor_evil:
Hmm OK, this leads me to believe that both of these have a bad ESN then.

I just bought a Cricket Wireless XT-1045 with a busted screen off ebay that I'm going to try to use the logic board in it to transplant into one of these XT-1042s as from looking at tear down guides for the original moto G and pictures of a XT-1042 and a XT-1045 logic board looks like it should work as the boards look to be identical. I already have a precision tool set and spudger,etc. from when I replaced the charging port on a samgung galaxy nexus and then later did a logic board transplant on another galaxy nexus that had a ripped volume control ribbon, so I'm familiar with doing it. The tear down actually looks pretty damn easy in comparison to the galaxy nexus.

Will report back if I am successful.
[Moto G Q&A, Help & Troubleshooting] Abu Siona:
You should be good to go with the transplant. Even the Xt1034 uses the same screen and back covers as the XT104*.

[MENTION=6488483]Abu Siona[/MENTION] [MENTION=4789600]dblackburn965[/MENTION] I'm in the same situation. I have a Moto G that the computer recognizes as a 1045, but is really a 1042. T Mobile works pretty well but ATT doesn't.

What do I need to do to make it work on ATT?
[Moto G Q&A, Help & Troubleshooting] Abu Siona:

[Moto G Q&A, Help & Troubleshooting] harryspar:
Ah, I misunderstood. So only [MENTION=4789600]dblackburn965[/MENTION] got it working, is that right? I wonder what caused the difference.

Oh well. Does it pay to try flashing anything or am I wasting my time?
[Moto G Q&A, Help & Troubleshooting] Abu Siona:
I think the towers/bands that the phone is using is what causes it to work or not. If you roam using T-Mobile the phone will sometimes go into restricted mode and will not be able to make any calls. So anyone who gets it working on AT&T may be in an area where AT&T is using different bands.
[Moto G Q&A, Help & Troubleshooting] dblackburn965:
Does anyone know of a good app I could run that would check what bands I'm using? I'll try to figure out what bands my phone is running on if that will help anyone.

---------- Post added at 10:46 AM ---------- Previous post was at 10:25 AM ----------

Just took another quick look at my phone. I noticed that when I was first trying to do this, my baseband never changed, no matter what ROM I flashed, be it stock, or custom. I currently am running a lollipop ROM and I show a baseband of MSM8926BP_101.90.49.02R. Before it showed one that had USCS in it, which I'm assuming means US Cellular Customer. This is a long shot, but I'm guessing that after I changed my band settings using the qualcomm unlock guide and the number that Abu Siona suggested, flashing a stock At&t rom resulted in the baseband changing. This is just a guess, and I don't know if it's even a good one, but my baseband is different now. On a side note, the phone is back to being recognized as xt1042 on the pc, but is still working perfectly fine on At&t.
[Moto G Q&A, Help & Troubleshooting] harryspar:
I'm showing the usc_cust baseband. Any idea if there's a way to just flash the ATT radio / baseband stuff?
[Moto G Q&A, Help & Troubleshooting] dblackburn965:
Have you already done the band unlock? I tried flashing just the baseband, but it didn't work. When I first started trying to get this to work I flashed a .zip baseband from the non 4g version just to see what would happen. The baseband changed. As I mentioned earlier in the thread, it might help if we could get someone with a xt1045 to extract their baseband and give us a flashable zip of it. Unfortunately I wasn't paying close enough attention to when my baseband actually changed. If someone here knows how to create a flashable zip of my baseband I would be willing to try it. Then you could try flashing the baseband that I currently have.
[Moto G Q&A, Help & Troubleshooting] harryspar:
[MENTION=4789600]dblackburn965[/MENTION] thanks for the info.

My XT1042 was already partially modified when I got it (from Ebay). It won't register on ATT, but T-Mobile is about 90% (Good 3G, HSPA, and LTE, but calls are hit or miss: in some neighborhoods it cuts out despite good coverage, and in others it's fine.)

I'm wondering if some sort of band unlock was already done. Is there a quick way to check?

I don't have CDMA workshop or any of those programs, so I was going to leave it as is, but if there's something I could flash I'd try it. I have stock XT1045 firware and I'm wondering if I should try flashing it.
[Moto G Q&A, Help & Troubleshooting] Abu Siona:
If you flash the firmware it will remove the unlock. the xt1042 is only unlocked because of the bands edits.
[Moto G Q&A, Help & Troubleshooting] dblackburn965:
I just tried flashing a different baseband and I lost all connectivity. So now we know that it was whatever baseband I flashed that allowed the phone to work on AT&T. Now I just have to figure out which one it was.:confused:
[Moto G Q&A, Help & Troubleshooting] harryspar:
Wow! Thanks for the warning!

I wish I could reproduce [MENTION=4789600]dblackburn965[/MENTION] 's success, but if even you couldn't then I'm giving up. I'll either return it or just use it as is.

EDIT: just saw [MENTION=4789600]dblackburn965[/MENTION]'s latest post. Let me know if you get this figured out! I hope you didn't flash that because of me :mad: I'd feel really bad.

And thanks so much to all of you for all the help.
[Moto G Q&A, Help & Troubleshooting] harryspar:
Could I trouble you to explain for me - which unlock will I lose? The SIM or the bands? I'm asking because right now I have good TMo LTE but not much GSM/HSPA and calls cut out, pretty much what you described in post #22.

I'd be really happy if I could get TMo calling working well.

What makes the most sense to try. Should I try the NV edit? Flashing firmware? Both?
[Moto G Q&A, Help & Troubleshooting] Abu Siona:
Flashing the different firmware does not seem to matter much as far as the signal goes. You will lose the sim unlock if you flash a new firmware. The band edits will have to be done again to get the sim unlock back. I suggest trying to edit the NV to unlock different bands. Just remember the bands that are being used now so you can revert any changes if needed. if there is a way to find out which bands the towers in your area are using, that would be a great help.
[Moto G Q&A, Help & Troubleshooting] harryspar:
Appreciate the advice!

Help a newbie out - the link in the Qualcomm unlock thread to the files at d.st never works for me. My browsers (Chrome / Firefox) block the download because they say it's malware. What's a safe way to get the programs needed to edit the NV?
[Moto G Q&A, Help & Troubleshooting] Abu Siona:
when i get the malware alert in chrome it will sometimes allow you to keep it. Choose that if the option is there. If not then you may be able to go to the downloads in chrome and the file will be there and also a recover option. This will allow you to get the file. If all else fails you can try to get the files using IE or Opera browser.
[Moto G Q&A, Help & Troubleshooting] harryspar:
That worked. Finally, a use for IE! :p

So I flashed RETUS 4.4.4 and then wrote the NV. It didn't change much for me.

Here's what happens with me. I get LTE everywhere on Band 4.

If I turn off the LTE, in some areas I get HSPA+ and in these areas I can make calls.

In other areas if I turn off the LTE I get nothing whatsoever. The connection cuts out totally and it says "No Service", and I can't even make calls.

I don't know how to check the GSM/HSPA frequencies in use.

I'm going to experiment with various NV settings to unlock more freqs when I have time.
