[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;

I hope it helped

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

[Q] [Help] Debranded M8 does has no LTE/4G

Hey guys,
I hope somebody can help me with that one.
Ago some days I got my HTC One M8 and its O2 Germany branded.
After going through all the procedure of unbranding(unlocking bootloader,s-off,changing CID,international european Stock Rom) I found myself in a situation with a not working LTE connection on my phone. I've tried fixing it with one app called "LTE OnOff" to force using LTE only but it didn't work.
The international european Stock rom for my phone just gave me HSDPA or EDGE/GPRS connection but not LTE.
After trying some Rom's in the hope of fixing that problem I reverted back to my branded O2 Germany Backup.
Only that gave me again a LTE connection.
Does anybody know how I can fix that problem and have LTE on other roms too ? Or is that not possible ?
Thanks guys I hope my english isn't that bad, I didn't used it for quiet some time ..
Copy your apn from stock Rom. Grab your stock radio. Flash Rom. Flash radio and enter apn. I'm not 100% but I would think this would work for you.

Very weak/no network signal on F180S

Hey guys I have a LG F180S and I converted it to E975 with half success... I have everything working fine but without my network signal. In my home I have 0 bars where my second phone is in the same network and has 2-3 signal bars always When I had stock ROM on my LG the baseband was M9615A-CEFWMAZM-2.0.12034 and now on CM11 I have BM9615A-CEFWMAZM-3.0.10663. Going to stock ROM using .kdz files isn't helping - still the same problem. I have lost all my hope in getting back the network signal Do you guys maybe know where can I get that first modem? Please help me, I don't have 132$ to spend in the service to get my stock ROM back with working signal
Any one can help me? Please

My only suggestion would be to try flashing different modems... I had a similar problem, although under different circumstances. I described the problem, the steps I took and the results here.

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?

I`m in BC
Unfortunately I won`t be able to change my phone now... since the hardware is pretty similar i thought that it could work :crying:
I was wondering if is it possible to flash the D852 rom into a D855P device... And if something wents wrong if i could flash it back. Does anybody knows ?

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!

3G is not working on LG G3 D855

Hi Everyone,
I hope you guys will be good.
I have flashed cm13, Bliss pop, XenonHD etc.. on my LG G3 D855, cm13 and Bliss Pop were better from others in my opinion.
Unfortunately 3G isn't working on every ROM I have tried I have searched the issue a lot and tried tons of solutions including suggested here:
http://forum.xda-developers.com/lg-g3/help/cm-13-nightly-3g-problem-t3264442?nocache=1
Entered into hidden menu *#*#4636#*#* tried to change preferred network type to GSM, WCDMA and whatever was suggested in some forums.
Its very unfortunate that nothing worked for me now this forum seems my last hope.
Just to confirm I have now installed the stock Firmware (Marshmallow 6.0) before that it was on Lollipop and on both 3G was working perfectly fine.
So, Its not the network issue or something. It seems to me the ROM issue.
Just a little addition I live in Pakistan. And supported band here in Pakistan for 3G is 2100MHz
Thanks in advance for any help.
Regards,
Nadeem
