[Q] Which baseband for LG Optimus L7 (P705)?

Hi Everyone,
I would like to flash a V20 baseband on my Australian P705 as I'd like to upgrade soon to one of the custom JB 4.3.
I am currently on Slimbean 4.1.2 with baseband V10e.
I don't want to brick my phone or have any issue with it by flashing the wrong baseband on it so could someone please advise which V20 baseband would be the one to use on my phone from this thread: http://forum.xda-developers.com/showthread.php?t=2335273
Also, I was wondering if I flash a V20 baseband, could I go back to V10 if needed?
Thank you for your help!
And sorry, I would have posted the question on the thread above but I am a new member and restricted in the thread I can post in!

Anyone would have an idea? I just really don't want to use all signal!
Thanks!

I risked myself to install V20e baseband.
I had signal from my phone provider but in "About Phone", in the Baseband line I had "RRO" so not sure why or what it means.
I also installed Slimbean 4.3 which didn't seem really stable and I lost root privileges in the process and couldn't find a way to root a LG L7 using JB 4.3 so I went back on baseband V10 and Slimbean 4.1.2 until we get a more stable JB 4.3.
I'll keep you up to date if I find a working solution.

Yeah I knew that, it's just between JB 4.1 and JB 4.3, we need to upgrade the baseband from V10 to V20 and there are plenty of V10 versions and plenty of V20 versions with different letters (e.g. V20a, V20e,...) and I wasn't sure whether I could use any of them without any trouble or not.
I tried V20e temporarily on JB 4.3, I could still get signal from my phone provider but the baseband didn't seem to be properly recognized in "About Phone".

Hey mate, any luck with this? I'm in the same boat as you, except I haven't tried any of the various v20's yet... I'm on v10e also, so logic says I should upgrade to v20e - but there even two of these - one says "PL" and the other for "GBR"... I'm with Vodafone AU and have no idea... I don't want to brick and am a little worried :/

Hey mate,
I think I upgraded for V20a but I can't remember. Baseband is just showing RRO in About Phone but it's working with Optus in Australia and overseas.
I remember I had to upgrade the Baseband first before upgrading Android otherwise it didn't work!
I am also using Slimbean 4.3 Beta 5.2.
It's working OK.
To be honest, don't bother, it's not worth it playing with custom ROMs!
At least not for the L7!
Battery life is even worse than out of the box (even with Greenify), features from newer versions of Android don't work because this phone is not compatible with them (I'm thinking of Photosphere which was the main reason I wanted to upgrade)
In my opinion it's just a waste of time! I'll try a custom ROM of KitKat when stable but if it just keeps getting worse on my L7, I'm just gonna go back to stock!

Thanks. I ended up trying the v20e (both of them) with Prime KitKat rom. I installed all this before I read your reply and all is good - except for the network reception. I'll go back and try the v20a now. This phone isn't my daily driver, just a mess about so I'm keen to try KitKat out on it while I wait for OTA on my Note 3. So far, other than the current mobile data issue, this Prime 4.4.2 rom seems pretty good Thanks again

[q] what version my g2 is?

Hi. I am new user of LG. I bought a Korean version of LG G2. Friend of mine flashed international version (as per his saying) of KK. Phone is rooted as well. Now phone's software/hardware specs are as follows: Android ver 4.4.2, Kernel 3.4.0 Build No. KOT40I.D80220b, software vers. Lightning v2.0. In hardware info section it is Model No. LG-F320L. It is now confusing for me either my phone is D802 or F320L.
I want to flash recovery in order to flash custom rom. Please guide me what my phone is now, D802 or F320L? Which phone version recovery is safe I should flash? Thanks for any help.

It's definitely a F320L then You can take back cover off, right? And there's place for a MicroSD? If yes, then it's a F320L

My friend, I know it is originally Korean Version (F320L) and I am using MicroSD as well but firmware flashed on this is not the original one. The software version is Lightning v2.0. Before this on original software(firmware) there were many Korean softwares and after flashing current firmware (which someone else flashed for me) there is no Korean thingy on phone and it is all English and rooted as well.The build no is also changed. My question is I still need recoveries prepared for F320L or recovery matching to build no. KOT49L.D80220b? Because all recoveries are for different variants and I don't know which is for my phone. Bottom line is I need a working recovery on my phone so I can try different custom roms.

You should most definitely flash a custom recovery for F320L then
There are many D802 Roms built on Korean firmwares but that doesn't make the core things of the phone Korean, and that's what you should look for when flashing.
Your ROM is just built around a D802 Firmware but everything is modified so it matches your F320L. I hope this helps!

Honestly, since you're running a custom ROM already, I think you have a custom recovery installed for how would you otherwise have a custom rom :laugh:?
Please try turning your phone off, and try factory resetting your phone using the button combination - that should take you to the custom recovery

Be careful about the build.prop entries.
If there is wrong build info (d802 instead of some other let's say..) and you unroot, and you have no recovery and want to use download mode, the lg tool detects it's d802 and you can't flash your proper kdz..
It's most likely because of your current rom. If the rom cook provided variants in aroma then he didn't provide seperate build.prop's (or entries)..

Exactly same thought come to my mind and I tried to enter in recovery mode and found a full page in Korean language which is for sure is not recovery I used always.

I have problem
[email protected] said:
Took me a while to find this on my old posts, but here it is. This should work with EVERY d802 kitkat aosp based ROM out there so here it goes:
All you have to do is look for the Meta-inf folder>Com>Google>Android and the updater-script file should be there. Download Notepad ++ and open the updater script with it.
The first lines that you have to edit should look like this:
Edit them so it looks exactly like this, and make sure to keep the same format. All you have to do is change the "d802" and "galbi" for "d803"
Like this:
After that, replace the boot.img with the Furnace Kernel boot.img (the one made for aosp, it works with most 4.4 roms), save and close the zip. Put it in your phone and flash, along with the G-apps and optionally the QuickRemote.zip if you want to get remote functionality.
If you don't feel comfortable with replacing the boot.IMG yourself, skip the boot.IMG replacing part and go straight ahead and flash the modified ROM.zip and afterwards flash the furnacekernel.zip
If I didn't make things understandable, just say it and I'll take the time to explain more when I get home. I'm replying from the phone and its kinda hard to do quotes and stuff on chrome

Depends on what Kernel and rom you used. Ever since they updated roms to use either LG 4.4.2 sources or just JB sources it got a bit tricky. It seems youre using a JB kernel on a KitKat sourced rom.

Hi guys, I'm new here from hard bricking Claro 803/801. I'm very confused on what to install and what not - the official version of TWRP seems to be 2.6.32 but there is a 2.8 material design version. Again with roms, I'm not sure what is allowed and what is not. For someone fairly used to Cyanogenmod on my One X and also having heard of Cloudy G3, what would you guys recommend

Question re: D803 vs D801
Hi, I was referred here from a reddit sub while looking for information, it looks like there are lots of knowledgeable people here so I thought I'd post.
First off, for context, I'm a complete n00b when it comes to doing any sort of modifications to a cell phone; pretty much everything I've read here over my head. Rooting? Flashing? No clue what those are
I currently have a D803, and I love this phone. But, I do NOT love my carrier, as I'm being charged ridiculous fees, so I'd like to switch. The problem is the carrier I'd like to go with does not support the D803, as they use the AWS 1700 band (from what I can gather), which means I need a D801, in theory.
I saw someone advertising they can modify my model of phone (among others) to work on the carrier I'm interested in, for $25. Do you guys know if this is even possible? If so, could someone explain to me what the risks would be?
Thanks!

While I cannot speak for the LG G2, I know that with the Skyrocket I was able to flash a modified rom to have it work with Wind's AWS system. It only worked in places close to their towers but never very well. However since the 801 (T-mobile) works on AWS you may want to buy one of those/swap or maybe see if you can flash that radio (D801). NOTE: I cannot guarantee that will work and flashing the wrong radio may seriously damage your device, or so I've heard.

but when i instal this rom my phone's touch breaks, giving multiple touch points at a time and dead zones, imei becomes 0 and baseband is aslo not present and phone memroy appears 10gb on computer.

this is the correct firmware for you. this is not a ROM but a full fledged update that you must flash using update tool. I suggest you ask on main forum about this problem...but one thing is clear. do NOT use claro update, or you may hard brick your phone.

Hi, really thanks for the support. Now I have LP F320L30D, i flashed it with KDZ guide. If i would go back to Kitkat (when it was when i bought it) what should i do? A simply flash with KDZ file like i did for LP? If so do i need to root + twrp before the kitkat installation for a fresh install rom by cleaning cache,dalvik etc or is enough to click CSE install by KDZ program?

If you want to go back to kitkat stock, just kdz back to it. No need to root or clean any cache. Just use the tool , download the kdz file and flash it via tool.

I asked that, because i have a problem about the mic during calls. I mean if i call or someone call me, the person does not hear me or hear my voce really really really low. Should be a software issues. I disabled "ok google" but nothing.

Are you having this particular issue on lollipop stock or all the rom your tried?
If its software issue, you can switch a rom and see if it gets resolved.

I had this issues like 4 days after i updated via OTA the Kitkat version that was stock (21Y) for another Kitkat version (22k) if i remember well. To be honest, dunno if this could be the problem. I though (hey, maybe this OTA ****ed me) so i changed the rom into 30D stock with KDZ method so i installed Lollipop. Now i choose to come back to Kitkat Stock maybe i can fix this. By the way in the xda server there are located 3x firmware for my model (F320L) so korean model
F320L21V_00
Korea LG U+ Kitkat F320L21P
LG u+ F320L11G
Which one should i take? In the original was called U+ 100% LTE.

If so then take the second one that says U+ and its a korean variant.
Honestly i dont own this variant so i know little much about these since i haven't performed any flash. I only own verizon hence i mostly help people based on successfully performing those actions by myself. I don't like to give you any directions without actually performing it irl so you choose which one is for your variant.
And if you ever want to go back to stock , just flash kdz. That would be all.
Good luck!

And if you ever want to go back to stock , just flash kdz. That would be all.
Good luck!

Need help with a galaxy s4 gt-i9505

Hi everyone,
just a long-time forum-lurker in the dark here, now I'm here asking for help to restore my galaxy s4.
Here's the story:
gt-i9505 no brand, italian official firmware 4.4.4 (kitkat), never updated, only used towelroot to gain rood adn unistall couple of unused apps.
everything worked fine
Then i decided to upgrade to lollipop.
downloaded last samsung lollipop rom for my phone from sammobile, made a full backup via TWRP Recovery, and installed lollipop via Odin.
Then the nightmare begun :
1st problem, no modem, no connection, only wifi, i restored EFS, still not working, reinstalled modem via odin and then i got my imei and connection again.
2) think i've tried to change the rom to a custom downloaded here (i don't even remember the name), then i tried couple other roms.
this as far as i remember
Now the phone has a samsung original lollipop rom, wifi won't turn on, data not working, knox status is obviously altered (so i cannot restore it via kies or whatever the software name is now) BUT It overheats a lot after few minutes and i'm forced to shut it off to not damage it.
I'd like to restore it to a full working condition, i think i've messed up with bootloaders, modems and roms from different android versions.
can anyone help ?

Hey, @dokrobei
Take a look on my Guide.
You need the guide clean install from the scratch. Please read it carefully till the end. There avaible links with all necessary stuff like modem/bootloaders/stock rom-firmware/recommend customs roms etc.

Hi @Retrial, thanks for the answer..
I've managed to reinstall stock KitKat 4.4.2 and working modem drivers, following another tutorial here. Now Wi-Fi, 3g and bt works fine, BUT the phone overheats a lot. It's not a battery problem and sure it's software related 'cause it wasn't like this before my stupid first attempt to upgrade to lollipop.
I've searched the forum for the overtheating near the flash zone problem, some say that is a microsd problem (wich I removed), some other that's a battery problem (wich is not in my case).
Do you think I should start from scratch again following your guide? IHow do I know wich modem / bootloader is right for my phone? I think the problem is there, maybe wrong modem version..

First of all there is no need to still be on KitKat...a lot of apps don't support Kitkat nowdays...and is outdated.
I will recommend first to proper upgrade to Lollipop stock and then use some of the latest android Pie Custom JDC Roms by following my complete guide. As I said above there is a full guide with links and very well explained steps. The latest Firmware for our S4 i9505 is QK1 - No matter which country you will choose, and it's recommened to have the latest. Just read it carefully till the end and check the asterisks.
The overheating it may be no compatible Modem/Bootloader since you messed up with Lollipop. To check what Modem and Bootloder you can simply install "Device HW Info" or "Phone Info" app and check.
Let me know how it goes, and if you have any question or problem feel free to ask. Good Luck :fingers-crossed:

rebooted to check if everything was working using stock before going to custom...and...
it started overheating as soon as i tuned on wifi. i only managed to install phoneinfo to check wich modem i have as you suggested, then i had to turn the phone off it off cause it became reeally hot and i thought i could break it. modem chip is "mdm9215m". any suggestion? maybe i should try to instale all the lollipop modems / bootloaders from your post...

After every flash the device become hot. Let the rom settle for a while.
If you have PK2 Firmware then you need PK2 Modem and Bootloader. So no, don't try other modem/bootloader.

I flashed it last night and checked if it was working this morning. I'm sure the high temps are not related to the usage or to the battery. It become hot eachtime i turn on wifi. Havent tried with data but I think it will be the same thing.
