[Q] Help with F180L on US T-Mobile

Hi,
I've got a brand new F180L phone with baseband version APQ8064/MDM9x15M and software F180L20s.
After searching forums I still cannot make heads or tails of this phone...
My questions are:
Can this phone be flashed to work on US T-Mobile network?
If yes, what is the maximum data rate possible?
Is there a good tutorial on how to do it? It appears this phone can be hard bricked by flashing wrong radio so I would like to avoid such mistakes.
I live in the "upgraded" area with 1900MHz frequency re-purposed.
Thanks in advance!

Hi there,
I am having the F180L and have flashed the E975 european version on it. It is working as good as stock, no issues so far in India with 3G, HSPDA or 2G (we dont have 4G yet). And ofcourse, all korean crap gone
The process is failrly simple, you just need to read through the forums, there is everything written here.
From here you can find the ROM's just pick one near to you; may be Europen E975 http://forum.xda-developers.com/showthread.php?t=2093382
Then use kdz to flash it on to your phone. No need to root your phone or else. Use google to find how to.
Root your phone
Then flash baseband of F180L;
A detailed description is here; http://forum.xda-developers.com/showpost.php?p=40477925&postcount=70
I hope it helped

As I see, problem still is there. If your F180L worked before, works after.

[Q] How to return to stock AT&T E980AT from Korean F240S ?

Hi,
I am not sure if this question has been asked before as I could not find anything similar here. If it has already been asked, then I would request the moderators to please point me there.
I have an AT&T Optimus G Pro (E980). It was running the stock rom (AT&T E980AT V10g). I then flashed the value pack from AT&T (AT&T E980AT V10k) which I downloaded by following the download link provided in thread http://forum.xda-developers.com/showthread.php?t=2438088
The flashing tool I used is the one that required the .tot file and the .dll file. Flashing was a success.
I found the value pack 10k to be laggy compared to the stock 10g. So, I wanted to try out a new rom and flashed a Korean one (SKT/SK TELECOM(KOREA) F240S V10w). I did that using the flash tool and the kdz file given in the same thread as stated above. Flashing was a success.
Now, I want to return again to the AT&T stock (AT&T E980AT V10g). But, when I am using the .tot file and the .dll file, the flashing tool is showing an error something about the device model being different and that I should check the .tot and .dll file. I cannot paste the exact error message right now as I am not at my desk but I can paste it later, if required.
Do I need to have a kdz file of the stock to carry out the flashing ? If yes, then where to find it as the stock firmware thread in this forum lists only the zipped up .tot for the AT&T stock rom.
Else, do I need a .dll for the F240S model and then use it along with the stock E980AT firmware to flash ? If yes, then where can I find the .dll file ?
Thanks for taking the time to read this post and thanks for helping out This can serve as a reference to someone who is looking for the same answer.
Regards.

Okay, I know exactly what your talking about!!, You have TWO Options!
1. (Easist) Change your Build Prop to be an E980 on your current rom and then try it
2. Flash the Telcel or Panama KDZ on your phone using LG Flashtools , and THEN flash the AT&T Version. That`s what I have had to do.
Heres a Guide in case you did not know http://forum.xda-developers.com/showthread.php?t=2420219 for flashing the Panama or Telcel rom.

Hi,
Thanks for showing the way. I am currently on the Telcel rom and everything is working perfect, though I dislike the bloatware in this rom, be it as less as it is
I wonder if you can help with the following questions :
1) What is the difference between the Panama and Telcel (Mexico) Roms ? I assume both are based on E980H but Telcel should have more bloatware, as it is from a carrier. How much bloated is the Panama Rom ?
EDIT : Got the exact answer for the above question in thread http://forum.xda-developers.com/showthread.php?p=45722192&postcount=1
Panama rom is almost the same as Telcel's, but without the extra bloatware. I am definitely going to flash this one
2) I am from India. So I tried out flashing the India Rom (E988). Though the flashing was successful, there was no mobile operator network. Is this because of some baseband/modem mismatch issue ?
3) Would you happen to know which all roms are fully working on AT&T E980 devices that will work in India. I have tried out the Korean F240S and Telcel roms and both do work.

Well as for Living in India Flashing a local rom does not always mean it will be better. As the device you have is meant to be in America meaning the India rom is pretty much gonna have its issue. I only recomend the Telcel or panama roms for the E980

LG E975 - No LTE Option

Hello Everyone,
Hopefully this issue can be solved, as I'm using stock Android JB 4.1.2 (E97510h-EUR-XX) on my device and there is no LTE option in:
- System Settings> More...> Mobile Networks> Network Mode
Now, I believe it can be enabled by making a change to persist.radio.lteon as found here:
- https://community.vodafone.ie/t5/Network/Supported-4G-Phones/td-p/137830/page/1
However, it requires root access and as far as I'm aware, there is no root exploit for E97510h-EUR-XX at this time:
- http://forum.xda-developers.com/showthread.php?t=2249033&page=2
- http://forum.xda-developers.com/showthread.php?t=2163814&page=5
Here are my questions:
1. Is there any method to replace or edit persist.radio.lteon without rooting my device?
2. If 1 is not an option, is there any method to successfully root my device?
3. If 2 is possible, can I unroot and will this process be undetectable?
Any help is much appreciated :good:

He hasn't bought a Korean Optimus G, but an E975. But for some reason if you put a SIM card from one carrier in the phone you cannot choose LTE, but if you put in a SIM from a different carrier you get the option to choose LTE. That's because LG has had the brilliant idea to block LTE for some carriers on an LTE enabled phone.
You can try contacting LG so they release an update so that LTE will be enabled for your carrier, but it would be faster to root your phone and adjust the build.prop like you said in the first post.

doesnt matter where mobile is form .. dont u see i bought from korea and europe soft was working but no lte so why he cant put korean onto european ?!?!?! it will still work + with lte enabled ..
contact lg god .. it is not down to them how do u want contact them and yeah they will tell you omg we are sooo sooryy we will correct it for you .. fkin pathetic .. they will crap on u .. man
lg doesn't block nobody .. the carrier needs send u setting .. dont u remember when 3g came up they been sending settings over SMS ? APN settings and MMS settings ? nowdays it is up to carrier send update over network NOT via sms .. and those carriers who has settings ready then 4g doesnt work ..

Why bother putting Korean software on your European phone and risk having a bad experience (due to the fact that Korean software is guess what optimized for Korean carriers)? When you can just root your device and change the build .prop which is less trouble and less risky to perform than to put a Korean software on it.
But to answer the question of the TS. You can root the E975 10 H firmware. I used Framaroot, and it works fine. You can read all about in the thread FAQ (Freaking Annoying Questions) in the Q and A section.

risky ? how can be risky .. so people here happily flashing third party roms and that's alright and when try to use original official rom then is risky ????! man are you OK?
optimized for their carriers ? no .. only APPS are included .. and those apps can be easily ignored ..
i think that your buildprop editing is risky .. ordinary people wont be messing with customizing files
wait for carrier till end of march then
I dont need to read nothing for me all working am enjoying LTE(4G) u dont it is your problem what u do ..
do what u want ..

Chill out dude. I'm only trying to help the TS out. He didn't ask anything about flashing a ROM, only to solve his problem with or without root.
Flashing any custom ROM is more risky than rooting a device. As it involves more steps then just rooting. So why make it hard for yourself?
Flashing a Korean ROM would mean flashing a KDZ file (that's the way I changed the E975 10 H back to E975 10 D) and that process probably changes the baseband of your phone(which is not the right one for the E975), so it could definitely influence the experience and battery life, etc.
You say that ordinary people won't mess with the build.prop file but they won't have any problem with flashing a Korean ROM?
BTW: There is no need in quoting the very last post everytime you make a comment, as it is clear what you're replying on.

That quote button has reason to be there .. that is why am using it ... And people know which answer belongs to particular person ..
for me is easy flash kdz ... and then obviously u need to flash modem back .. that is not hard too ..
And u are right in only one thing .. yes when people changing roms flashing then phone drains battery .. yes when I converted to E975 my F180S battery was very very bad .. I flashed original korean back and battery is much much better .
Like I said you can try korean if no leave it and wait for carrier to sort it out .. but they have time tho

No one here recommends to flash korean kdz in international versions nd vice versa too... Try some othr rooting methods nd try to change the build.prop.... Have yu tried moto chopper root method...??
Edit: looks lyk moto chopper method doesn't help yu... Yu cant yu downgrade ur software nd root it....

Official LG E975 4.4.2 Kitkat ROM

how many of u need the Official LG E975 4.4.2 ROM?
i have downloaded it somehow...a 980mb kdz file. and it works. its a U.S ROM.
:victory:

one more thing if anyone is interested..
lemme know t best site for uploading the kdz file..
or might hav to do as googledrive or dropbox or box

i'd like to try please.
you can use mega.co.nz or google drive.

If I flash SFR Rom on my GF E977-it will be sim locked ? I ask that because it's the only Rom with LTE band 2600 mhz that I could donload from lg phone firmware. There's some way to flash modem without custom recovery ?
I'm a Brazilian without English Course, sorry and be comprehensive

Yes please. Google drive would probably be the easiest upload. Then go to "share" and share with anyone that has the link. They will give you a link, post that in your OP.

Using LTE in Canada with a D855P

Hello my friends
I just had arrived in Canada with my D855P bought in Brazil... I had flashed it with a UK v20e and I can't get LTE working with Rogers. Does anybody know what I need to do ?
Thanks a lot !

Anyone ?
Even trying forcing LTE option in the hidden menu every signal is lost... any ideas ? My current carries is Rogers.

Im pretty sure LTE will not work. Best thing would be to check if APN for rogers is right. Or try to trade for d852. Where in Canada are you?

You cannot. And if you do , you could end up with a brick. That flash tool checks model in build prob i think , thats why if you flash wrong rom it will not work restoring with flashtool

@hmaqueda I have a D855 and can confirm that LTE works on Rogers/Fido. From my research the D855P is capable of connecting to LTE on Rogers (LTE Band 7 [2600 MHz]). I have written a guide over in the General section, here is the link: http://forum.xda-developers.com/lg-g3/general/guide-enabling-lte-d855-flashing-t2878434
If you have any problems, please let me know. Hope this helps!
