[Q] lg p936 android 2.3.6 tele2 reboot

My phone is rebooting when I use the internet operator (tim) or wi-fi, it happens two or three times after each battery charge normally. Did you guys can guide me? I live in Brazil and bought the unit overseas and got interested in it have 4g lte network, hd screen. I tried to update the LG support Portugal but continued with the same problems, to access the internet or youtube or GPS (google maps) that is most often occurs when rebooting. Is it hardware problem, or is the firmware. I even saw some upgraded their lg optimus lte 93x for official ics rom, but were having problems similar to mine, but have not seen anyone with such a problem reporting system gingerbread. Please help me, this unit is not for sale in Brazil.

Are you completely stock for example no root no custom recovery like cwm or twrp? If you are it could point to a hardware problem. The latest gingerbread p936 ROM is the v10i released in January this year. It is available as a kdz file on the internet (just Google it). Use the kdz installer available under general on xda. Try installing it to see if your problems go away. Good luck.

Thanks for the help Swetnes, v10i kdz installed and my phone is working fine :good:.
I have a question and I am noob, if you can help me again. The thing is, I was wanting to put the official rom v20c lg P936 for it to work with ics now the problem is, if you later want to change it again to gingerbread, ics if not work well, I can do using official v10i kdz, using the same tools I used for this update, is back from ics for gingerbread only flashing kdz files?

You can install any kdz file with that installer you used to flash v10i. If you want to install cwm so you can install many custom ROMs go here: http://forum.xda-developers.com/showthread.php?t=2044645
I hope this helps. Also make sure you are using the same kdz installer instead of the one in the guide if you have win 7/8.

P936 continues with random restart problems
Good morning, gentlemen.
My phone after install v10d kdz files, v10i, v20c (O2D and vodafone) continued to have random reboots, even worse when installed ics (v20c kdz) as well as random restart, still had to take the battery out and replace the handset to reconnect . Installed AnTuTu benchmark and checked on the issue of ram that my unit marked 768 mb of ram. I saw in the specs that the device actually has 1gb of ram in lg site. Is this is the cause of reboots? Took for technical assistance in Paraguay (where I bought the phone) has no technical assistance from lg and sale of the device in Brazil, I'm worried because technicians end up not take us too seriously. I explained to them that when used with frequency or internet connected the gps for some time and they will evaluate whether problem really. You have to post photo or check the device you in AnTuTu benchmark or other benchmark to see if my question makes sense?
thanks.

optimus g f180L baseband prob

recently i bought a f180L having stock firmware 4.1.2 than i followed following tutorial symbianize .com/showthread.php?t=1103182
and converted it to e975 and installed ind fw and flashed f180L baseband and also unlocked edge all was ok till here. than i rooted it tried to install
cwmr using rom manager but when i booted the mobile and pressed vol down and power it didnt went to recovery than i pressed vol up and
pressed power here where it stuck with security boot loop so i again flashed the f180L orig fw and here when problem started as there was
NO SIGNAL. now i read many threads here in xda also tried many firmwares also installed ics 4.0.4 no signal but when i installed a 18mb update
for ics 4.0.4 using built in updater full signal came back but when i switched off the phone and turn it on again there,s no signal also installed
open europe 10h firmware the phone shows weak signals and some time no signal. i have tried many basebands using cwmr too but still no
signal. now i totally fedup and tired i think i made a mistake by not taking efs backup with original firmware. what should i do now ?

open this file https://mega.co.nz/#!L54n3TjD!GF5xgTzYX1BslEzVMU9QHkQ6SKZsAOZIMEBtNR2udCw
Extract folder "BaseBandF180L_OK" (there was no problem in WIN7 with this procedure) and then:
- connect the phone to USB in MTP MODE and copy "BASEBAND.IMG" to SDCARD ROOT
- check "DEVICE MANAGER-ADB INTERFACE-LG "something"" (it should be OK - only if hou have installed drivers in WinXPMode and you are connecting the phone in WIN7 then you have to install those 3 files from point 2 and 3 above)
- so if you see ADB Interface for LG, you copied the IMG file to SDCARD and your phones ROOT is OK then ...
- just run "FLASH_BASEBAND.BAT" and wait for restart
- now you should be asked for PIN (if you use it ) and you should get a signal (greditsfor all this i going To Happy_Alien)not me

restore efs(i didnot do that but only flash baseband) and then flash the baseband.be sure that your phone is rooted ,mtp mode,usb debagging and uknown sourses enabled.try to flash jelly bean not ics.
the baseband you have is from jelly bean

Finding the right stock firmware

Hi,
I have a galaxy s4 mini gt-i9515 lte on the three network on the UK. I'm currently running cyanogenmod nightly but wish to flash back to stock for gear compatibility.
I'm having trouble working out the right stock rom.
The only one that matches my baseband is the Spain movistar rom.
Is that right? Will that have me all Spanish? What would happen of I flashed the rom for three? The baseband doesn't match, but I don't know if that's an issue?
Thanks.

I have the same as yourself and after looking on SAMMOBILE and other places I would be wondering what to use too. I'm not sure what the last update 3 have released in the UK but it looks like it might have been XXUAMF5 which you can download from here. I have a copy of it I downloaded last year as a go to stock ROM if I needed it. You can always use Kies to check for updates after.

Excellent, will give that a go. The movistar one appears to have "issues"

RIght, so the H3G one didn't work as I've got an unlocked phone from Carphone Whorehouse. So I had to go with the BTU I9515XXUBML4, and that "works" only my NFC won't turn on and my wireless is INCREDIBLY unstable, just stopping providing any network connections.
Is that likely to be a "Wrong Stock ROM" issue, generic Stock Rom Issue, or an "I've messed my phone up" issue?
Ran just fine on Cyanogenmod, and I had /some/ wifi issues on the original ROM, but not like this...

I doubt you have messed up the phone. There is a collection of ROMs here. Perhaps you need to flash a compatible kernel rather than the CM one. Sounds like you don't need a branded ROM or anything.

[Q] Not Registered on Network Problem after manually upgrading to KiKat 4.4.2

I upgraded my Note 2 from 4.1.2 to 4.4.2 (Official French Rom downloaded from sammobile) yesterday and facing Not Registered on Network Error when I try to make call. My phone is already modified before I buy. This originally came from UAE and modified in Pakistan. I faced same problem when I upgrade to 4.3 which I could not resolve myself after trying so hard. I got it fixed by moving back to 4.1.2 with help of a technician (spent money).
Now again, I tried this latest firmware out of my curiosity. But same problem again? Please help me what to do?

nomore 5G wifi anymore

after doing a fresh install of "D85510l_00.kdz" that i downloaded from http://lg-firmware-rom.com/ for my IMEI now i dont have 5G at all.
i have restarted my router few times even changed the wifi name but my G3 doesnt even see the wifi name.
my old HTC ONE X see's it and can connect just fine.
so somehow i lost 5G capabilities, not sure why. can anyone help out?
thanks

checked other stock KDZ file as well, Northern Europe D85510A_00.kdz, same issue. no 5G.
so i rooted that and installed supersu and twrp and then installed rooted v20c lollipop and voila! i can see my network again.
then restored stock KDZ back (both of them), no 5G.
anyone?

Have You try KDZ from other source? or different version, i personally use 10h so far the best form me and i don't have any issues on this version, also wifi works great at 2.4 and 5 GHz, i have AC router.

well these 2 have this issue so far:
-Northern Europe D85510A_00.kdz from this post: http://forum.xda-developers.com/showthread.php?t=2785089
-D85510l_00.kdz from this website: http://lg-firmware-rom.com/
roms with no issue are rooted lollipops installed after rooting any of the first roms including:
-D855-20A-Official-skin1980
-LG_G3_D855_Stock_20C_Bumped_Fixed
i have also downloaded few stock d855 lollipop KDZ files inc:
-D85520A_00
-D85520C_00
but these have UI issues when flashed on cleaned/wiped device so i cannot check whether these works with 5G or not.
im really confused with these issues on this phone and its roms.
