Rooted LG P935 need clarification about Network/Carrier Locking

So ive gone ahead rooted my P935 many times now quite simple to do. The question is its a Telus phone i'm with rogers, when i flash the v10f kdz i get origninal GB korean rom fully unlocked phone shows using rogers network. When then doing nitro hd unbrick guide and if i only DD the system.img file to install the att version p930 then do the battery pull factory reset my phone still is network unlocked. What i'm tryin to find out is which .img files baseband firmware etc would control this network lock, since when i tried to flash H!ONO v20c P930 cmw flashable ics leak my phone became network locked again. Ijust cant seem to straighten it all out , information overload .

That's very strange, flashing ROMs should not affect network lock. I'm using Bell P930 on Fido, I've flashed AT&T leak and Bell official ICS and neither have re-locked the phone. As long as the IMEI remains unchanged you should be able to use the original unlock code you received to unlock the phone again.

Interesting indeed would it be the v10f .kdz korean somehow. And heres the thing I have recieved no unlock code to unlock. And now am back to running the CM9.1 unlocked working on Rogers Network .

Aha! I figured it out. CM has your Rogers APN preconfigured. The official roms would not lol. I don't know why the SU640 rom was letting you connect. It really shouldn't because your firmware and baseband should be incorrect if you flash it. Anyway, APN has nothing to do with your phone being locked or not

w0095157, are you certain your phone was never carrier unlocked by someone? Did you purchase it brand new in box from a store?

brand new in box i swear, telus store,. must be a fluke. but it works id like to find more information on different radios modems, which may change service for me, but i was comparing this to what iphone 4 service was saying side b y side.

Yeah, that makes more sense. Unlock codes are $2 off of eBay, it's worth it just to make sure you don't have any hassles switching between ROMs.

Does LTE work on Rogers when using the Bell unlocked version (P930)?
I know you have to get an LTE Sim card and an LTE enabled plan, but before i buy on eBay and update my plan, i was wondering if the LTE band works on Rogers even if it is a Bell phone.
Yes, i have LTE in my area.
Cheers!

I don't live in Canada, but from what I'm able to find online, Rogers and Bell are using compatible LTE frequencies so it should work just fine.

It works!!!

So after trying million and 1 things I made it work! Baseband and firmware go together and I thought they contain the SIM/network lock so i tried changing them, but apparently all the versions i tried were locked too.... so since the Korean version is with unlocked SIM, why not change directly from it to Cyanogen build ??? Because the wifi is not working!!! and since i did not manage to fine how to install in while offline (CM or Clockworkmod) i flashed from the Korean version just the system.img and voila! I have unlocked SIM with working WIFI ... so putting CM after this was a breeze!
so:
1. flash to Korean V10F_00.kdz
2. root the phone
3.adb shell
su
dd if=/sdcard/system.img of=/dev/block/mmcblk0p27
should have unlocked SIM + everything else working on the ATT version which you can now install Clockworkmod and go for Cyanogen mod of your choice. i did cm-10-20121105-NIGHTLY-p930.zip - works great!

I have a p930 with at&t permanent locked network, I discovered too that the baseband of the korean version is unlocked, I made a thread about this but nobody commented or cared i think lol, you can install any rom you want but remove the baseband of the rom before install.

Ok I have a similar problem with an at&t Lp 930, did the unbrick guide to sim unlock with the korean baseband. While in the koream ROM sim was succesfully unlocked. But after following the guide, flashing to AT&T Gingerbread and installing ClockWork Mod, I flashed it to HO!NO! AT&T ICS CWM Flashable ROM once in ICS, I lost Sim Unlock and was back to: Network Locked on Phone.
So what your saying is to basically only flash the system.img after the korean ROM is on the phone and ignore the other images, then after flash to desired ROM with CWM?
And if so, if I flashed to HO!NO! At&t flash, would I still have Locked Network?
Thank You

[Q] UK 4G not working

So far, managed to root my Korean F240L, still running 4.4.2 for now until there's a root for Lollipop. Haven't managed to see any 4G signal in the UK since I got it , get 3G sporadically but the reception is way worse than the same sim card in my old Nexus 4. Network is Giff Gaff (ie O2) , should I consider going for a UK baseband update ?

Right ok, since found out that the Korean version doesn't support UK 4G. Is it possible to change this ?

If the phone doesn't support the LTE bands your desired carrier offers, then no, you're boned.

Think I'm in a similar situation
Got an E986 from Germany running 4.4.2 KitKat (E98620a-EUR-XX), it works great on 3G in the UK but NO 4G at all on my Three 4G Sim card. Tried enabling it in the hidden phone menu - no joy.
I thought I would be able to get 4G working by rooting and re-flashing but by god I cannot get this thing rooted despite my best attempts from trying all the techniques on here
Thought if I downgraded to 4.1.2 then I would have better luck rooting, but can't seem to download a .kdz that isn't corrupted when I try the LG FlashTool

You cant change the bands of a phone by flashing other things. If it doesnt work it most likely wont be able too.

My LG G3 only connects to Edge network

Hello guys.
After a couple of days reading on the internet without success I decided to share my problem here.
I bought a LG g3 D850 32 gb on eBay, once I received it I was so happy enjoying the 4g LTE network, the speed was amazing.
Regrettably, one day all this happiness disappeared, now I only have Edge connection, I don't have 3g, hsdpa or 4g, I only get the awful Edge.
I have tried using my sim card on other phone and I get 3g and hsdpa (that phone does not have 4g) so the problem is on the G3.
I have to say that I have the phone with the stock rom and the only change I've done was to root it with kingroot and deleted (disable) some at&t apps. I thought this was the problem so I restored to factory defaults but the problem did not disappear.
I was thinking in to return the phone but I am in Chile so is a little hard.
I will be grateful if some one could help me with this issue.
I will be waiting for your comments
Thanks on advance

What model number/version/baseband/etc.
What's your base network and are you sure your APN settings are correct?

Hi Nick,
This is the Software info:
Android Version: 5.0.1
Baseband Version: MPSS.DI.2.0.1.c1.13-00058-M8974AAAAANPZM-1
Kernel Version: 3.4.0
Build Number: LRX21Y
Software Version: D85021r
Security Software Version: MDF v1.1 Release 3
I do not understand what the base network is. Is my cellullar provider?
The APN settings are OK. I didn't change anything.
I had all the connections and suddenly I lost 3 and 4 g and only get Edge.
I didn't change anything. I rooted the phone with KingRoot but I am not sure if the problem started in that moment.
I have made the Factory Data Reset a couple of times and the problem continues.
My Sim Card works fine in other cell phone.
Please Help!!!!

I had the same problem when I switched the operator. Went there and the man there tried everything but nothing helped. Last thing he suggested was to do a software update, did it an 4G speed came back

But is so weird the problem because I had 4g and I did't change anything :crying:

Yes, your cellular provider. What's your cellular provider and what's your APN? Is your sim from AT&T, a foreign provider or from a Chilean network? Does the APN match the SIM provider's APN?
I'm thinking that it's either an APN problem or a band switching problem (since you disabled some AT&T apps) or you just ran through your allotment of 4G data under your contract.
If you've tried your SIM very recently in a friend's phone and it works just fine, then it's probably not a data allotment problem.

I am using a chilean provider with the correct APN, the same I used from the first day when 4g were working fine and the same.
Yesterday I tried mi sim card in other cellphone and I got 4g without problem. I checked the apn and they was the same.
Now I tried with tho different ROMs, I changed the kernel and the modem and I'm still get only EDGE :crying::crying:
I do not know what to do. I think the cellphone is bad

I'm guessing that you may have disabled something when you were deleting the AT&T bloatware. You've got a D850, right?
As @trickie69r has mentioned in a previous thread, try downloading your KDZ direcly from LG's Servers using: http://csmg.lgmobile.com:9002/csmg/b...XXXXXXXXXXXXXX
(Replace XXXXXXXXXXXXXXXXX with your own IMEI, which can be found by dialing *#06* in Dialer)
Take a screenshot of your About Phone > Software Info tab before and after and see if anything changes.
Buena suerte!

I have tried to download the stock rom but I can't download it from the link you send me. I can't find D850 stock rom.
Do you have other link to get it?

Lg g4 us911 10a (us cellular lg g4) what are my options after root

I got this phone off ebay for a deal 330$. My plan was to root and install an aosp rom.
I have rooted the phone but cannot find anyway to install twrp. Seems like all the twrp recoveries and custom roms are for tmobile and international versions
i was not aware when i bought this phone that it would be a us cellular version the ad did not say
anyways what are my options? Is it possible to get an aosp rom on this version of the phone any advice would greatly be
appreciated

Unfortunately there are no options as of now. The bootloader is locked and there hasn't been a workaround discovered for it yet like for other devices.
At best you can root and flash xposed on the phone as long as it has Lollipop, but as it looks now, you won't be able to keep root if you upgrade to Marshmallow.

will i even get the marshmallow update, i have a us cellular version running on att network

The US Cellular model will most likely get MM soon, but if you're on the AT&T network, you won't get the OTA. I'm not sure if you would have to put a US Cellular SIM back in temporarily to get the OTA download, or if you could just remove the AT&T SIM and download it over WiFi. Otherwise, you could just get the kdz when it comes out, plug into your computer and force the update that way.

yah but even with the mm kdz file comes out it will be for us cellular and the phone will become carrier locked and i will have to go thru the hassle if getting unlocked. btw my firmware version is us99110a i bought it off ebay. the seller did not specify it was under any network just said network unlocked. but like i said my firmmware version is us99110a which i believe is a us cellular firmware

US991 Marshmellow
Hi Guys,
I am having a real issue here after reading this tread. I recently upgraded to marshmellow but my data stopped working. I cannot get the H+ anymore. I need to go back to lillipop. I am looking all over the internet trying to find out how i can roll back. i even factory reset the phone but is goes back to marshmellow. do you have a clue how i can do it?
I asked around and they directed me to http://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
My software version is US99120c.

Can I get help rooting the 10a? Every tutorial I see is 10c and I can''t update mine.

Vs985 Fulmics status/imei resetting to 0000 on tot flash?

Hey guys, I have an LG G3 now on 47A that I updated using LG Flash tool/kdz. Unrooted and stock. I want to flash Fulmics but every thread says that the older versions of Fulmics didn't have working mobile data and bad connectivity for the Verizon variant. Is the new version the same? Also to root my phone and flash twrp, I heard about the tot method. However, many users say their IMEI reset to 0000000 and their phones were unable to connect to any network. How true is this? Did anyone experience this as well? Thank you everyone in advance!
Note: i am using a non Verizon 4g Sim. As of now, 4g and networks work seamlessly. Ive tried the following carriers on 4g and they all work: T-Mobile US 4g, Airtel IN 3g and 4g (both sim cards work), Vodafone AU 4g.

The VS985 variant takes on the ROM flawlessly, but yes there have been reported data issues regarding using the variant with the Verizon network. I believe it stems from the international GSM rom built around the GSM radio interface layer. I would NOT be surprised to see that T-Mobile and others work well, but you will need to research the Fulmics thread to know for sure, as I only know that my VZW SIM does not work properly. (3G only)

Seems like SMS/Calling worked for me...but had troubles with MMS. Others were able to get both working with Textra/Handscent/etc but not the stock messenger app. It's been awhile ago since I tried the international ROM's and they're all kind of a blur from some reason. Not being able to get signal bars working was a deal breaker for me (travel in the states quite a bit) so I broke away. I believe the XSPIRIT is working on fixes for the international ROM. Once his source code becomes available it should open up a world of LG Goodness. Currently , the ROM's I tried were Andy's, TekCafe, LG Prime, Fulmics....all display the same problem, the ability for Verizon SIM's to completely work properly.
