[Q] Long journey of a F180L to E975 conversion

I bought an F180L ( F180L - Korea LGUplus - LTE (LGUplus Band) / GSM / WCDMA / CDMA) ( it was a mistake, I was told that is the same as E975 and took it for granted. Already regretting it.). My goal is to be able to flash the latest custom roms and have good data connectivity ( if I am only able to have 2G speeds, it's no good). These roms are mostly created for E975. After browsing a couple of topics:
http://forum.xda-developers.com/showthread.php?t=2334023
http://forum.xda-developers.com/showthread.php?t=2434917
http://forum.xda-developers.com/showpost.php?p=38438579
I understood that the F180L to E975 conversion is not an easy thing :|. Even impossible.
Because I am not so familiar with modding and I will struggle ( I have to google search most of the terms here; my experience only includes the unlocking and rooting of mere two android phones), I created this thread in order to make this trasition as safe as it gets.
I have already rooted the phone with fromaroot. SuperSU is installed.
I tried to take EFS backup ( http://forum.xda-developers.com/showthread.php?t=2164749). I assumed that I need to install a custom recovery ( CWM) or is there a stock recovery that can do the work? I pressed volume down+lock key and it only offered to return to stock condition.
I then tried to unlock the bootloader with FREEGEE. Well, that didn't go as planned either: i am seeing a white screen and in the notification bar it says installing, while it is already installed. Already istalled BusyBox ( I assumed it wanted me to, as when I pressed on the Freegee app icon, it sent me to busybox app in market).
Kind of outside my waters, would appreciate any hints

Hi!
I had the same problem - got an F180L (name Optimus G is the same as on the real E975)...
My problem was/is that FreeGee bricked the phone totally! Only download mode still working... I was coming from rooted stock Korean ROM 4.1.2. (F180L20S or F180L20R)
With the download mode I flashed TeenyBin and pushed via ADB a custom rom (CM10.2 that time) and GApps,
voila - CM10.2 installed.
Do not use TWRP as it has a different model identifier and you would have to modify CM ROM everytime you flash them, stick to CWM 6.0.3.7!
Also - do not flash any different BASEBANDs - as it is korean, you cannot change the available frequencies with simply flashing a different!
In germany I could live quite good with the korean one - LTE was no option for me (which would never work in germany though with a F180L)
But 3G and 3.6G+ (HSPA) was working well! (2 different networks tested: Vodafone and O2)
Hope thats helps a bit
But my next step is: revert back to stock as described in this thread:

As I got my Nexus 5 and want to sell my good "old" F180L

Thanks sunyakram
Both methods tried - no success!
Not that I have a problem with a rooted phone and CM, but others might have...

[Q] Prepare for transition: 10L -> 20E & back.

Hi,
I have 855 (generic European version), V10L, rooted (using towel rooter), no TWRP, all OTA (since July 2014) installed automatically and seamlessly so far (keeping the root).
Today I got a prompt about V20E available upgrade.
I have LG PC Suite up-to-date backups of this device, and anyhow don't have anything that can't be restored, but in general prefer to not reconfigure everything manually.
Did nothing so far.
Questions:
Is it worth to move to V20E, is the version stable enough, worth to wait for V20F or whatever comes next ?
If I decide to proceed now, I want to be able to return to my current state (I do not need to fast switch between multiple roms, just way to get back V10L with my current configuration).
I prefer the way that allows me to keep receiving OTAs, and not to flush next updates manually.
After looking on the forums I though about the following workflows
First (without TWRP):
1. Create one more backup using LG PC Suite.
2. Unroot (just to be safe).
3. Accept OTA.
If I understand correctly I will loose root here, and it can not be restored (for now).
In case of need to restore:
1. Follow LG G3 Stock Firmware (Go Back to Stock) to flash D855 V10A. I hope after flushing it will receive 10L OTA ? Am I right, or I will be stuck with 10A ?
2. Restore my existing backup using LG PC Suite. If I do restore on V10A, will it bring me back to 10L ?
3. Reroot if needed.
Second, with TWRP:
1. Install TWRP.
2. Create full backup from inside TWRP.
3. Get prebumped Lollypop image (I see only V20C here. Where can I get more recent versions ?)
4. Install it and reroot if needed.
In this case I must reject upcoming OTA prompts and flash future prebumped images manually.
To restore
1. Restore full TWRP backup, and I'll get V10L with all my stuff preconfigured.
2. If at this step I want to get rid off TWRP, can I remove it somehow ? Will it restore the phone to the current state (rooted, V10L, able to get OTAs) ?
Sorry for multiple questions but currently the whole process looks a bit unclear for me.

Q: Is it worth to move to V20E, is the version stable enough, worth to wait for V20F or whatever comes next ?
A: No V20H got released today and its probably gonna be available in your region really soon
Note: If you do ever want to install stock lollipop please be aware LG backup cannot save the appdata of any system applications such as chrome etc etc
Q: Follow LG G3 Stock Firmware (Go Back to Stock) to flash D855 V10A. I hope after flushing it will receive 10L OTA ? Am I right, or I will be stuck with 10A ?
A: Check (http://lg-phone-firmware.com/index.php?id_mod=41) and download the v10 firmware the corrosponds with your country. If the firmware has a 6 in front of it its for the 16GB variant
Q: Where can I get more recent versions?
A: http://forum.xda-developers.com/lg-g3/development/stock-t2961073
Q: If at this step I want to get rid off TWRP, can I remove it somehow ? Will it restore the phone to the current state (rooted, V10L, able to get OTAs) ?
A: Yes, by flashing stock recovery.img. Restoring your TWRP backup will restore the phone to the current state

Thanks, but I am not sure about this one. What is the process ?
If I flash stock kdz it will remove TWRP, but I will not be able to restore TWRP backup (without TWRP), right ?
Is it possible to first restore TWRP backup, then flash "something" that will replace only TWRP, leaving android OS intact ?

Before saying anything, I would just like to give you a thank you for your post, it's very clear and pleasant to read. Looks like you also did a bit of research before asking so that is also very good :good:
So, I'm not gonna be able to help you a lot about the backup thing because I like to always start fresh when I change Rom or if I want to go back to stock. I backup my data manually and restore what I want to. Using a Google account it will automatically reinstall your apps, but you'll have to reconfigure them manually.
Anyway, I also got a D855, French variant A6FR. (A6 means 16GB) You can check what is the latest version that LG offers you by checking the link bellow. You just put your IMEI at the end and it will give you an XML with information about your phone, like your specific variant (German, UK, ... don't know where you are from) and the latest firmware available for your and a link to download it. For me it says D85520F_00 so it's LL version F.
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI
So, you can go back to stock using the KDZ method and with the firmware LG offers you (removing root, revovery, ...), but as you probably now, LL is not rootable. To summarize, that is not really interesting unless you want a STOCK STOCK LL.
But you guessed right with the V10A. If you go back to stock with this version, it will remove the root, custom recovery and anything else you have, you will also end up with a completely stock G3, but KitKat G3. There is no obligation to use V10A, if you find a KDZ of a later version you can use it too. Of course we are talking here about V10something not V20 that is LL. Just make sure to use a version suitable to your phone (16/32GB).
Flashing that, LG will be happy and will let you do OTAs. So if you flash V10A, it will give you all the OTAs untill the latest available. So you can go V10A --> V10B --> V10C --> ...... --> V10L --> ..... --> Lollipop
You won't be stuck with V10A.
Now if you want a rooted LL, you will need to use a custom Rom. In the Dev section you can find for example GloudyG3 that is based on the stock LG rom with a few enhancements. It is currently based on V20F and will probably move to V20H which is a brand new version that went up like 2 days ago.
To summarize
KDZ with V10something allows you to go completely stock and give you official OTAs. It can be rooted.
KDZ with V20something works too and will give you OTAs, but is not rootable, so if you want a custom rom, you will have to downgrade to V10, root and install TWRP.
Flashing a KDZ always erase everything on your phone.
If you flash a custom rom, you won't have LG's OTAs so you won't have to worry about rejecting them.
Before doing anything crazy, backup your EFS (basically your IMEI partion) with TWRP and manually. Always nice to have several ways to do it.

How to unlock the Samsung Note 2 CANADA (SGH-I317M)

Hello! Now, I am a new member, And solely for one reason..
I AM UNABLE TO FIND A MODEM FLASH FOR 4.1.1 BASEBAND I317MVLUDNH2
Now, I have searched EVERYWHERE, and, all the Rom's are for the I317, and if it is for the I317M, I am unable to download for some odd reason.
Now, Here are the links i've searched through (Just incase I missed something)

http://android.stackexchange.com/qu...317-att-samsung-galaxy-note-2-on-jelly-bean-4 (links back to first link)
So, I am basically out of ideas. All i want to do is DOWNGRADE to 4.1.1, unlock the phone through the hidden menu, Then go back to 4.4.2. (Since i got the phone from a friend, and am currently using a rogers [Well, More of a Petro-Canada] Sim...)
So, Would I be okay using that Rogers flash? With Phrilz OR TWRP?? Or how would i go about this???
FIGURED IT OUT!!!
Okay, Here is a rundown on how to do it:
1. First download TWRP https://twrp.me/Devices/
2. Download the ROGERS Modem firmware http://d-h.st/rJq
3. Download Odinhttp://androidhost.org/get/PVAIv
4. Enable USB Developer Mode
5. Put the Phone into Odin download mode (Shutdown. Hold down Power+Volume Dwn+home. When the Bootsplash shows, Let go of Power button. Press Volume Up
6. Open Odin on your computer, browse to the TWRP .img (if you haven't already unzipped it, Do so) In the PDA section
7. Hit start, Wait till it is finished
8. Now, Open the phone directory in your windows manager thats built into the OS.
9. Drag the .zip into your main phone directory ( / )
10. Shutdown the phone, Hold power+Volume Up +home. Do it until bootsplash is done. (same as step 5)
11. In TWRP, select backup, then backup the MODEM folder. (I honestly forgot this step, If you have. There is links for the original baseband.)
12. Once that is backed up, You can either upload it to your desktop (i'd recommend doing that) Then, Open install, Browse for the .zip for the MODEM, then flash.
13. The system will reboot back into TWRP, just pull the battery out, and insert it back in, boot up the phone.
14. Type in your dial: *#197328640#, UMTS, DEBUG SCREEN, PHONE CONTROL, NETWORK LOCK, Then select option 4. Reboot phone
The simcard should now work!! Now, You can either install the old firmware you backed up, or just leave it.
New firmware for 4.4.2 Incase anyone Needs it: http://www.sammobile.com/firmwares/database/SGH-I317M/
Hopefully this helps anyone. It took me 5 hours to find out all this info (because the phone is a I317M, Not the non "m" version)
THANKYOU FOR ALL THE WORK OTHERS DID FOR ANY OF THESE PROGRAMS USED!!!!
THIS DOES NOT WORK ON CUSTOM ROM!!! You must have the original Stock rom, or atleast something close with the samsung stock dialer, as the code only works on those.

Thank you for your detail instructions. Recently I got a used a SGH-I317M locked to Rogers. It has firmware 4.4.2. Will it be safe to follow your instructions to flash the 4.1.1 Rogers modem only, do unlock, and then restore to the original 4.4.2 modem with twrp?
Thanks,
Howard

Yes that should work (So sorry for the late reply, I haven't been on this site since I made the post) Just make sure to backup before you do anything incase it does happen to screw up Just remember to select that last link (sammobile) and get the firmware FOR YOUR NEW CARRIER, not the old one.

I need to unlock my At&T note 2 but it is now running 5.1.1 Bliss Pop. I tried that code but of course it wont work.
I sent the IMEI number and paid to have it unlocked but the company I sent the money to said they could not unlock it either.
What would I have to do to this phone to unlock it. I am in Cananda this week and want to use this PetroCan sim card I paid for.
Thanks

Okay, this is quite simple, install TWRP as usual, but backup the MODEM you have right now for 5.1.1, Then follow through the instructions, and install the MODEM you backed up after. That shoould work, if not, try to find modems for the phone for 5.1.1, But usually, (if my computer knowledge is correct) a new OS shoould support and older modem, so, you can try 5.1.1 with a 4.4.2 modem.

your second link modem
it has tons of popups and when its not trying to open new windows and ask for browser access etc it downloads a "flash file" your 1.4mb download is a exe and puts up a warning.
since samsung removed the menu entery they left in by mistake on early 4.1x releases there is no way this ork to do anything but install malware and trojans from your site.

You can extract the modem from the stock 4.1.2 ROM or you can flash the entire stock ROM in Odin, unlock, and flash back to the latest stock ROM.

Please identify my SM-T705 build!!!

Hi there,
I have the Samsung Galaxy Tab S 8.4 LTE version, which I purchased through Ebay - I believe it came from Asia somewhere as it showed up with an international adapter for the power supply. It was sold as a "Verizon" model - I ditched that sim card and have been using it with Bell Mobility in Canada.
Recently, I tried to update my firmware using the latest version of Samsung Kies and I'm running Windows 10 latest version. For some reason Kies needs to reinstall the USB driver before performing the update to the firmware and this causes Windows 10 to crash without fail. (This is also happening to my Note 3 - Samsung informs me Kies is not compatible with Windows 10 although it seems to work for everything else - just not the update). Kies doesn't seem to care that I already have the latest drivers installed.
I can't update via the tablet because my device has been "modified" - rooted.
Finally I went to Sammobile for the firmware, however I can't find any US firmware for a compatible carrier under SM-T705. I am debating flashing the Bell Canada firmware, but the model is listed as SM-T705W. In case this is not ok and I need to revert to the original, I'm hoping someone can help me identify my build? The samsung agent offered to identify it but once she discovered it was from outside Canada she said she had no information. So much for Samsung International!
Please help! I'm having battery issues and I'm hoping updated firmware will help, plus I would like to have the latest version of Android. Thanks!

If you're in Canada then just flash the Canadian firmware.

Hi there, forgive me for being thick, but how do you tell it's Cellular south, and what do you mean by region XAR? I'm sure that the fellow I bought this unit from flashed US firmware, however I can't find it on the Sammobile site - in fact I can't find any US carrier firmware listed for this model.
As mentioned above, I did find Bell mobility (Canada) firmware listed for the SM-T705W but nothing for the SM-T705.
Further explanation greatly appreciated!

You have root so install twrp from the development section and do a full back up of your current system.
You can then restore as you please.
Seems no US firmware for the t705.

LOL... ok now I have another problem. I had already downloaded the Bell mobility file from Sammobile and hadn't seen this response - in the meantime I hooked up with Odin and my download failed twice - I don't get it. I just did my Note 3 10 minutes ago without any issues. Rebooted device and odin between both attempts.
Thoughts?

Don't flash anything until you make that full backup with TWRP, trust me it will save a massive headache should you need it.
Download Flashfire from the link below then set your date back to August, run Flashfire then load up the firmware, select the Flash firmware package option.
From the partitions list select system.img and boot.img only.
Under the reboot options select download mode then hit the flash button.
Once it has flashed and booted to download mode you will need to flash a lollipop bootloader (assuming you are flashing lollipop?)
You will find them in the bootloader thread.
After that just reboot the tablet, it will take about ten minutes for it to fully boot.

Uh... ok you lost me early on. I downloaded the file - how do I install it? I remember using the TWRP thing several phones back when I was messing with custom ROMs. I had a problem with recovery and since then have never gone this route - I've been happy with stock rom and root - installed using Odin... sortof the KISS principle.
I can try TWRP, but could you dumb down the instructions a bit - as I mentioned, I'm a bit thick - particularly with some of the terminology! LOL
This is the file I downloaded - yes, Lollipop - I don't understand why I have the Odin Fail - google isn't helping me understand either. I have root, USB debugging is enabled and I followed the same steps as with my Note 3 - the message said write fail.
http://www.sammobile.com/firmwares/download/52301/T705WVLU2BOE4_T705WOYA2BOE4_BMC/ Is this what you mean by bootloader?

Ok but those "bootloaders" are custom ROMS are they not? And I don't see my device on the TWRP site - I have the LTE version, it only shows Wifi.
Really all I want to install the Bell stock firmware (assuming it is indeed compatible - SM-T705 vs SM-T75W) I linked to from the Sammobile site and then do Chainfire's auto-root.
Why isn't Odin writing the firmware to my device? I've never had this issue before and I don't see what I might have done differently with this device - it's the first time I've tried to update it, but I had no trouble rooting it with the chainfire auto-root.

No they are bootloaders they are required to boot the firmware , roms are the os.
Odin won't flash because certain devices will refuse to flash another regions firmware.
My advice to you is to flash the lollipop bootloader first, to make sure it will flash then flash the firmware with flashfire.
Obviously make the twrp backup first.

Ok I flashed the bootloader, and then I tried to flash the firmware with Odin again but it still won't do it - write fail again. I've never used flashfire - windows 10 won't open it...
UDATE: Ok I read to transfer the file to the download folder on the tablet, and then install on tablet. So I did that, but when I click on the icon it doesn't run. How the heck do I use this to install the firmware update?

Figured out the date bit, ran Flashfire.... problems during the install - got stuck in boot loop - tried a factory reset - that didn't work... stuck in loop. I think I'm bricked....
Left the default settings in place - very little in the way of instructions - read the bit about not trying to write over protected settings...
And got this:

You're not bricked as long as the tablet starts up and you can boot to Download mode.
I've seen that error with corrupt downloads so not sure why you're getting it.
Reboot to download mode. Just hold POWER + HOME + VOL DOWN until the device restarts and boots to download mode.
Doesn't matter if it's boot looping.
Reflash TWRP and restore the backup you made earlier. You will be back to where you started.
At this point I think the best option is to flash a custom lollipop rom.
There is a very good one I use on my t805 which is practically stock with a bit of bloatware removed.
Its in the development section called sweetrom.
At least one positive is that you were able to flash the lollipop bootloader, so upgrade is not impossible.

I'm definitely able to get to download mode - I was surprised that the factory recovery mode didn't work. I'm wondering if the file from sammobile is corrupted - I used the same file with Flashfire - now I think Odin was trying to save me. I'm downloading the same file again fresh, and it looks like Telus and possibly the other Canadian variants are the same - unless it's the same corrupted file.
I just hope the problem isn't because my phone identifies itself as a straight SM-T705. That is why I asked about that point earlier. There are plenty of straight 1705 options available - just don't know which country would be compatible - particularly for the modem.
I didn't understand how to use TWRP and I've had problems with it in the past (recovery) when I did figure out how to use it and was messing with custom ROMS a couple of years ago. I would really like to get myself back in order with a proper stock ROM and root. This tablet belongs in my car and right now I just want it to work properly - I'm using Torque to resolve some ongoing engine issues and it will suck if I have to go back to using the small screen on my Note 3.
If there is any way to figure out which of those countries for the 705 are compatible with Canadian carriers, in case this Bell firmware is defunct, that would be appreciated.
As well, is that bootloader going to cause any problems with stock firmware? I've already flashed it - does stock firmware come with bootloaders included?

OK before I go any further with this I need you to install twrp and make that back up. Twrp is now very stable.
Twrp will back up some very important partitions namely the Efs and modem. Don't take this warning lightly. The amount of people that have soft bricked their device because they didn't do this.
Boot into twrp then simply select the backup option and make sure the partitions on the left are ticked particularly boot,
Efs and modem.
Now as regards which firmware.
I would forget about installing the Canadian firmware.
It looks like this firmware will only install specifically on a Canadian device.
It doesn't really matter which firmware from which region you install as they are pretty much all the same except for the carrier ones which just add more bloat and some csc specific stuff.
Just go for an international rom. You've already flashed a bootloader from one of these roms so that proves you can flash.
Use odin to flash.
If you have connection issues afterwards then all you need do is restore your modem backup with TWRP.
That's why it's important you do this.
Follow these instructions and we will get you up and running.

Whole again!

For the record, I read elsewhere that it is NOT recommended to flash other letter variants of a model. In the meantime I downloaded all four Sammobile Canadian Carrier files and they appear to be the exact same file and all install attempts failed For anyone else with an actual SM-705W I read in this thread: http://forum.xda-developers.com/galaxy-tab-s/general/t705-lollipop-t3099945 a fellow Canadian was having a problem with those same files. Dunno what happened with him in the end, however I tried one more W file I found elsewhere that appeared to be different but it failed as well.
Based on the comments in the above thread, I flashed the Hong Kong variant for the SM-705 from Sammobile - apparently it was the first firmware widely available and users from several countries posted they had used it successfully. So far it seems to be working ok - after flashing it, I did a factory reset on the device as was also recommended in the above thread. Sure hope the battery life will be better than before - love this tablet but I've never seen a device drain so rapidly! CF-Auto Root restored!
As a side note my Ebay seller did reply to my origins query and was helpful once he realized I wasn't complaining about the device and wanting to return it... LOL. Apparently my unit originated in Singapore and arrived with that firmware along with a Verizon SIM which I never tested. As long as the OS is smooth, and the modem compatible, and unless someone advises a better country variant, I guess I'll stick with this one.
Now just need to get Torque reconfigured!

I'm from uk and have flashed many kdz from different regions without any problems. Currently I am on 20w-eur the latest for uk is 20u.I have flashed from Poland and Spain before without any issues although I would recommend flashing kdz roms near to your country ie if you are in the UK not to flash a China kdz but technically I think you can flash any.
Remember to read the LG Fashtool guide thoroughly and do not disconnect until your phone as thoroughly flashed and rebooted.

I am from Romania but the phone is unlocked.
I have a little bug which really annoys me: When i select swype to unlock the phone, after i swype, there is a little lag, around 0,5-1 second, before the virtual menu buttons appear. However, if i select PIN to unlock the phone, this lag doesn't appear and the virtual menu buttons appear instantly.
I was wondering if there is something to do with my rom, V20t, and i wanted to try a different one, but i want to be sure it is safe because this is my first LG and my first experience with flashing roms. I am full stock, not even rooted.
Thank you.

Nothing is 100% safe but if you want the latest firmware without too much technical knowledge then using flashtool is probably the best way to go.
Just follow the instructions on how to use flashtool and make sure you understand everything and you will be ok.Just remember don't unplug your phone from the computer until it as totally flashed and rebooted and you should be fine.
I have used flashtool many times and not had any problems you could always wait for the Android M update ota but that may not be until after Christmas.
