a friend of mine gave me a bad esn sprint LG G2 that he bought off on craigslist. It has the ZVE firmware and I succesfully rooted it using stumproot. I install all of cloudyFa's roms on it, but for some odd reasons it won't pick up my tmobile simcard. I go to "phoneinfo" and no matter what I switch it to from WCDMA preferred to GSM only etc.... it just keeps saying "emergenc calls only" So i'm wondering if it's because of the bad esn that's keeping it from recognizing my Tmobile sim card. Anyone can help me?

Try a regular unlock on the device first.
regular unlock?
when you say regular unlock do you mean have the device unlock through Sprint first? I don't think Sprint will give the unlock code because the Sprint LG G2 has a bad esn. If what you mean by regular unlock refers to modifying the software then unfortunately that is something I'm not really good at, but I'm a risk taker - I don't mind attempting to do the regular unlock even if the bad esn sprint Lg g2 gets messed up in the process. Is there anyway at all for you to show me how to do the regular unlock? I saw in another topic about using Rom Toolbox lite to change some stuff, but when I install the Rom Toolbox lite app I have no idea how to use it - it's all very confusing.

I went to the link as you suggested and I downloaded the file that you provided, but it would not let me copy the folder carrier. I follow all the directions that was provided on the link, but when I check the carrier folder on the phone I notice there are only two folders. While the carrier folder on the TotalCMD folder had like 6 folders plus a file.
Hmm, not being a gsm user, I am not sure. Was there any information in the thread of someone else with the same issue.
One thing I think they didn't say was you have to be on zv7 or zv8. Unless further in the thread it says other wise. Still reading.

when I was handed the bad esn sprint LG G2, I checked the firmware and it was on ZVE firmware then I used LG Flash Tool and downgraded it back to ZV8 firmware. I have successfully rooted it also now on the ZV8 firmware. My brother-in-law has a sprint LG G2 and his work for tmobile, but only thing is his Sprint LG G2 has a clean esn/imei and mine don't. So i'm assuming mine is not working because of the bad esn. Oh well I will keep on trying and figuring out how to make it work.

Dinc's on verizion have an unlock code but its the same for everyone six zeros (000000). To switch a phone over your self you would need a pc a program called qpst, and all the needed info and prl file from the carrier your switching too. Its fairly complicated, but can be done.

Same method but sprint has specific lock codes. I believe there is an app on the market " mslreader " that can find you the code off of the sprint phone.
I have never unlocked a phone so I apologize if this is a dumb question, but if have a T-Mobile G3 but am on ATT will installing a Rom for ATT model brick my phone or do I use D851 Roms and change APN settings to make it work?

Flashing a rom for a diferent model will brick your device. Flashing a rom (in generally - e.g. CyanogenMod) will not affect the carrier (sim/net) lock. If your phone is sim/net locked you need a valid unlock code to use it with another carrier's sim.
Thank you and sorry for the question here I realized they asked to have questions placed in Q&A section I won't do it again.

do you understand your own question? Are you talking about sim unlocked phone? You are sim unlocked at this moment because you are on ATT. Are you asking about rooting your phone then? The bootloader is not locked on TMO G3. But like the answer given, you can not install a rom on an TMO phone that is not specifically developed that TMO phone. I have TMO G3 and swapped over to ATT several months ago. I was running a custom rom well before I switched to ATT but its a rom developed for TMO G3.
I suggest a lot of education before going down the rooting path and custom roms.
I have flashed a AT&T Rom on my T-Mobile phone. I had to flash the T-Mobile kernel after flashing the Rom, but it did work. I also had to go and configure the apn
I've done this on other phones,but have been scared to try it on my G3. No offense, but I need someone with more then 4 posts to verify this

You can't root it. Theres no known method. Zva and lower can dg to zv6 but if ure zvb and above no dg and no root
Posted all over the sprint threads
A 3rd party company may be able to unlock but without root you can't even edit the apn sprint has it greyed out. Sprint will if u r a customer of there's and you fulfil there requirements. So even of it is unlocked you won't get any data or mms. You can thank sprint for that

At this point in time. Never I don't like to say that but. Things always happens. But for now. All out of luck. Sell it get a rootable model or phone. I own a sprint g4 on zv6 rooted and it sucks not having any dev on it at all now all due to encrypted bootloader. Even the new twrp release is for lollipop only. If u look in the sprint threads there was a link for a company that unlocks mm sprint g4s but still without root cannot edit apn settings

You can with a unlocked bootloader. But to go back to Sprint you need the official firmeware which they do not provide to the public.... I have a G7 had it unlocked, different firmware installed. Had no service, . Tried to flash another firmware and ended up wiith a hard brick.. Got it back to the first unofficial sprint firmware, then had to have Sprint reflash the official firmware for the phone.. What's nice the bootloader is still unlocked.. Right now I would not even try anything. Best bet is to return if able, and buy a already unlocked version, so long as you can use it with sprint.

Man I just bricked the phone, first I tried flashing G710EM using LGUP and Partition DL (Select All) it failed almost immediately, after rebooting the phone it booted straight to Firmware Upgrade mode. Then, I got G710N20f, also tried to flash it using Partition DL (Select all), this time it failed at more than 70% step BackupGPT, now when I reboot the phone, I get the LG logo but after the screen turns to whitenoise like, it seems like it is still in Firmware Upgrade as I can still connect to it using LGUP.
Any ideas how to unbrick it? :crying:

Are you sure it is firmware (bootloader unlcok)? or sim unlock, there is a difference.. If you did a bootloader unlock you will get a waring saying. "Warning your software can not be check or is corrupt, please relock the bootloader". If you don't have this kind of message of this sort, then you just had it sim unlocked.

im just going by the ebay listing. It states"Your phone will be converted to a unlocked firmware version and that i can no longer receive ota updates".
My software version is G710ULM11e and my build number is OPR1.170623.032 and im on security patch level july 1, 2018 and android 8.0. When i go to the update center to check for a software update it states im using the latest version for my phone.
I did try a prl update and update device config and it states profile cant be updated. SprintDM notification shows that it trying update mobile network. it comes on and off every 3 mins or so.
I hope this is enough information to go off of! If you need me more information , please tell.
Also I did contact sprint via chat and they stated i could get my firmware back to stock but its 2 about 2 hours away from my city . itll be a like a whole day trip for me since i don't drive and would have to take a bus. I would love to avoid that.
Thanks!

that problem with the Sprint DM trying to connect every couple minutes is a huge problem with the bootloaders be unlocked you will have to go to Sprint and have them do it it takes about 30 minutes because right now there is no firmware available for Sprint anywhere on the internet. when I get a break from my new job I am going to try and install TWRP on my device and if I do it successfully I will be able to upload some firmware but that's not guaranteed.

Whether you had insurance on the phone or not should not have mattered. Sprint should have flashed the firmware, cuz that's their damn job. They asked me the same question I told them no and they still flash the firmware.

You have to be assertive or act completely aloof. If you are a paying Sprint customer, they will reset/reflash your phone. If no one in your immediate area can help you out, maybe you can mail the phone to someone who can get it serviced (heh I'd happily do it for free but hopefully there is someone a bit tech savvy in your own social network).
AT&T LG G8 - Want to flash stock firmware, possible? Trying to use it on Google FI and it seems hotpot and many other features aren't working. Phione is paid in full and unlocked. Factory firmware currently.
I want to flash my phone
So you're trying to flash stock on top of stock?
The request is to see if you can flash a bare LG unlocked ROM that comes with factory unlocked phones onto a phone that came with a stock AT&T ROM. The Att phone has now been carrier unlocked, is used on a different network, so the Att specific apps that replaced stock apps no longer work.
I was also wondering if I could do this with my Tmobile G8; unlock the phone, then flash the unlocked LG OS instead of the Tmobile version. My goal is debloat, and to be able to have the original Android hotspot app. Not to mention get rid of that terrible pink, loud, annoying carrier startup splash.
Also, I wonder if security updates would come faster when strait from LG instead of the carrier.

Let me know if you find a debloated is for a T-Mobile g8
Has anyone figured out any method that actually works for just flashing firmware to the g8?
Unlike Samsung phones where you can flash other firmwares via ODIN I don't think this phone has that ability. If you got to the ROM/Development section there are threads where people posted firmwares but no instructions on how to flash.

We can actually cross flash, but we need a modified lg dll to fool lgup into letting us flash any firmware.

Hello,
I've tried to flash another firmware on an AT&T LM-G820UM10i with LGUP and a firmware found on lg-firmware.
The LGUP restarted the phone in Firmware update mode, then on LGUP, I got an error
Error 0x5319, Not allow to change the device.(ATT_US->OPEN_CA)
So I've unplugged and reboot the phone. Still working.

Because the G8 and all newer LG phones have security measures to prevent cross flashing.
Many bloatware apps can be Disabled in App Info Settings. The rest can be removed with ADB shell "pm uninstall". Google it.
It's best to never ever buy carrier devices. There's a reason they're the ones sold with a discount :cyclops:
