[Q] Kies closes on GB27 update

I'm trying to update my old phone which is now my sister in law's. It's stock unrooted ICS FL24.
When I try to use Kies to update, it gets through the first step of dowlnoading firmware upgrade components, but when it reaches 100% the window hangs for 30 seconds or so and then disappears and Kies closes.
It's the most recent version of Kies, I even uninstalled and reinstalled it, but it's still doing it. Has anyone come across this and a way to fix it? My sister in law wants the update but I can't seem to do it for her.

Oops, my fault, I did mean unrooted. I've edited the OP to reflect that. Anyway, I'm going to try it on a different computer

I'm having the same problem on my girlfriends stock unrooted phone

What worked for me was using an Odin One-Click package from here.

Use that link to download an Odin One-Click tool that will make your life easy. Whether you're looking to root her phone or keep it un-rooted, there is a tool for you on that page. Download whichever one of the tools you need whether or not you need to root her phone or keep it un-rooted. RESTORE versions will WIPE all user data from the phone. NODATA versions will NOT wipe user data from the phone. After downloading the one-click tool you need, simply turn off her phone and once it's fully powered down, press and hold volume down and the power key at the same time until you see the Samsung Galaxy S2 logo. You can let go now. It will boot into something called "Download mode" and that's what we need.
I'm going to assume you've already installed the samsung drivers since you're using KIES. If not, get them from here and install.
Make sure the phone is FULLY CHARGED at this point.
After the drivers are installed, launch the Odin One-Click program and wait for it to appear. Once it's loaded go ahead and connect your phone to the computer. Make sure your phone is still in download mode before you connect to the computer! The top left box in that Odin window should light up with a yellow box with "0:COM#" in it, once that's lighted up, go ahead and click start at the bottom.
If you do not see a yellow "0:COM#" light up in the top left set of boxes, you may need to run the ODIN One-Click as an administrator.
DO NOT DISCONNECT YOUR PHONE AND DO NOT TURN IT OFF WHILE ODIN IS WORKING! Once it's done, it will change the bigger box on the left of the "0:COM#" to a green box with the word "PASS!" in it. Once this happens, the phone will reboot on its own. Once the phone reboots, it's safe to disconnect from the computer.
And that's it. You've skipped trying to use the crappy KIES software and you've successfully installed GB27 (JB 4.1.2)! I'd say it's time to celebrate!
Hope this helps you. Cheers! :beer:
(alternatively you could just follow the instructions from the page where you download your ODIN tool from... Thanks to "Admin" from that website for the post, garwynn from here for leading me there, and QBKing77 for instructions that taught me how to do this back when ICS just released for this phone. )

I've heard about a lot of people having problems with the no data version of gb27. I don't really wanna do the full restore one. Is there any other options out there?

No. Use a NODATA rooted FL24, install Titanium (PRO highly recommended), and backup all your apps, call log, sms inbox, etc.
Then put the Titanium Backup folder from your SDcard on a PC (or somewhere else safe, off the internal storage. External SD card is ok too).
Then run the RESTORE ROOTED GB27, which will repartition your internal storage, likely wiping everything. This is why you moved your backups. Install Titanium and restore your backup. Reboot.
Then reboot to recovery and do a nandroid backup. Copy this backup to your PC for futureproofing.
Now, if you want to be unrooted, you can Odin a NODATA UNROOTED GB27, and you should have all your apps and such intact, without root access.

I didn't have any issues with the NODATA that I did to my phone, and I got it from where I sent you... Maybe I just got lucky...

[TUTORIAL] Transfer F180L (20s) to E975 (EUR10h/other) - working signal

Hi,
I was working on "reincarnation" of F180L (20s) to E975 (actually EUR10h) for the last few days and I didn't find one 100% usable topic.
I had either Korean symbols/language and working signal or my language (CZE, ENG) and no signal - so I decided to have "Czech language with working signal".
I got the phone to working state yesterday, after reading about tens of topics and downloading about 7 GB of ROMs/basebands etc. and about 3 days of trying, combining, flashing, drinking a lot ... water only etc.
I put many topics into this one and I will hope it will helps to someone else.
Phone infomation (original):
F180L with 20s FW
HowTo "reincarnate":
1) Get KDZ file you would like to use - Stock Firmwares:
Link: LG Optimus G [E975] Roms/Kernels/Mods & Tools/Root (Daily Update) or Google
2) Get this package:
Link: F180LtoE975 (FlashTool and Root APK)
I RECOMMEND TO INSTALL THESE FILES/DOING FLASH ON THE COMPUTER WITH WIN XP OR IN WIN XP MODE (UNDER WIN7/8) (I had still PROGRAM NOT RESPONDING in WIN7 64bit - even in compatibility mode)
3) Install all files (3) from "F180LtoE975/KDZ_SW/KDZ Flasher.zip" archive - B2CApp, LGUnitedMobileDriver and MSXML and extract dir "FlashTool.1.0.54"
4) Switch off the phone - connect to USB
5) Turn the mobile on in DOWNLOAD MODE - phone is off and connected to USB - you see battery icon - now HOLD BOTH VOLUME BUTTONS (+/-) and POWER BUTTON (it takes about 3 seconds, then release - I tried to time it well many times, so be patient )
6) Look in the DEVICE MANAGER (in XPMode you have to connect the phone through upper bar first) and there should be "LG something" in MODEMS (if you don't see it then there is probably problem with drivers/connection - try to check points 1-5 again)
7) Now you have:
- downloaded your KDZ
- installed drivers and extracted folder "FlashTool"
- connected phone and DOWNLOAD MODE on it's screen
- "LG something" in DEVICE MANAGER-MODEMS
8) WIN7: in "FlashTool" folder set Compatibility Mode for both EXE files to WinXP SP3 first:
WinXP/WinXP Mode: just run as writen below :
- now run "WindowsEnabler" and click on icon in tray - you have to see ON icon in tray
- next run "UpTestEX" and set flash to (check image "01" for sure):
!DON'T BE RECKLESS AND CHECK YOUR SETTINGS BEFORE CLICKING ANY BUTTON!
----- TYPE: 3GQCT
----- PHONE MODE: CS_EMERGENCY
----- SELECT KDZ FILE: <CHOOSE YOUR KDZ>
----- NORMAL WEB UPGRADE TEST
----- UPGRADE START
- CHOOSE: DIFFERENT COUNTRY and language <WHICH ONE YOU WANT>
9) Wait and pray :
- phone should restart itself near the end (about 95%) - !IF YOU ARE FLASHING THE PHONE IN WINDOWS XP MODE THEN YOU HAVE TO CONNECT PHONE AGAIN THROUGH THE UPPER BAR IN WINXPM!
- you should se something like "FLASH COMPLETE/SUCCESSFULL" and "FINISH"
- it took about 25 minutes to me to complete whole process
- I recommend to do a HARD RESET of the phone after flashing
----- HOLD VOLUME DOWN (-) AND HOME KEY - THEN PRESS AND HOLD POWER BUTTON
----- release the buttons when you see LG logo (or try different timing/holding/releasing power button)
----- with POWER BUTTON confirm (twice) the reset
10) After boot your "reincarnated" F180L to E975 comes the part what took me 97% ot time to successfull "reincarnation" - get the signal (now you have iPod :laugh:
- in the phone enable UNKNOWN SOURCES (in SETTINGS-SECURITY) and USB DEBUGGING (in SETTINGS-DEVELOPER OPTIONS)
- connect the phone to USB - choose MTP and wait for the phone to connect (you should see him in "MY COMPUTER" as a device E975)
- from archive "F180LtoE975" (downloaded at point 2) extact folder "ROOT_OK" and copy "FramaRoot-1.6.1.apk" to SDCARD
- through file manager in the phone run that "FRAMAROOT.APK" file and ROOT your phone - only GANDALF works for me fine
- restart the phone and find and there should be added SUPERUSER in apps (if it's not then install some SuperUser app from Google Play (I am using this one)
- for sure you can install RootChecker
- next install CMW/TWRP- FreeGee works very well
11) Now you should have:
- phone with FW you choose (for example E975 EUR10h - check in SETTINGS-ABOUT PHONE)
- ROOT checked and working
- wrong baseband = no signal
12) Download this file:
Link: F180LtoE975_BB
13) Extract folder "BaseBandF180L_OK" (there was no problem in WIN7 with this procedure) and then:
- connect the phone to USB in MTL 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
Phone infomation (reincarnated):
E945 with EUR10h/<YOUR CHOICE> FW with F180L baseband + OK SIGNAL + ROOT + CWM/TWRP
Hope it is works ... thanks to all who made topics which I read a which helped me a lot.
Thanks for even a small donation ... if there will be any ... there will be more experiments.

Sorry for your trouble and long thread, but it took 10 mins max to do it. Don't know what guides you all are reading all over the internet.
Instead of all this, simplest is
1. Flash kdz 10x less than 1GB
2. wipe the phone
3. Root the phone
4. Use freegee to unlock and get cwm/twrp
5. Flash modem for f180
All this in 10 mins

I'm facing the same problem too. My phone went dead few days ago. Suspected on the battery problem. My wife accidently drop my phone at 1mtr height and suddenly my phone went dead.
At first i suspect softbrick. So i try to flash f180l kdz but failed due to error. After reading in thread i notice dat u cannot flash any kdz more than 1gb. So i downloaded hongkong kdz and succesfully flash my phone. But my phone still cannot switch on.
So wat i do is, i open the case and remove battery and put it back. After dat magically i can open it but no signal. So i root and then freegee and afterwards flash f180l modem.
Finally its working like charm now.

Its true as you wrote...
It looks easy and I found these steps too but:
- many KDZ links didnt work
- I wasnt sure to use freegee (and didnt try, cause there is chance of hard brick) - only CWM/TWRP without freegee and that "killed phone"
- I downloaded about 9 basebands/modems for F180 and only one has worked
- thats why I wrote it so detailed - and with own links and in the one topic

If anyone could please verify edge usability on his/her rom for f180, there seems to be a special kdz / baseband which unlocks international edge on korean(f180) device. I am in dare need of edge since my gprs network signal die out, where as edge signal prevails on my other device using same sim. Or if theres some other way to unlock edge i would be thankful

You need to unlock bootloader for recovery.
There is a very good post here about how to extract your modem iv done that to use the latest if you don't want to use Houston's.
You see everything you need already in here, no need to go out and search and get into trouble.

i flashed my f180l to e975 months ago..and bricked it several times..but i always find a way to restore it.
it seemed hardbricking is non existent anymore when flashing roms.
my phone is now an LS970 after flashing the miui rom..which is great.

Just flashing modem doesn't do anything to imei. It's the other partitions that do those things.

Never happened to me on my several phone's in 4 5 years.
It always the issue when the baseband.img is accompanied by few other files. Or if you flashed the baseband on wrong partition.

Problem flashing Indian KDZ image
Hi has any one been able to download and flash the Indian KDZ file E97510E_00.KDZ
which is provided here
http://forum.xda-developers.com/showthread.php?t=2320817
I have downloaded the file 5-6 times but i am getting error while the Flasher unpacks the file.
I have been able to flash European KDZ on my Phone but not the indian one.
Anyone faced similar problem or has any solution would be very helpful.

Thanks for this detailed guide! I am a n00b to Android and found it perfect. Agree with OP that many links/files in other posts are dead and it's confusing. Good to have it all in one place. Thanks :good:

2) after converting the phone, can I use roms for lg e975 for this phone?

[Firmware](Upgrade+Root/Downgrade/Unroot) Files+Flashing Guide [TOT/KDZ/TWRP] 7/07/19

This is for LG G3 D851 ONLY
TOT/KDZ/TWRP Untouched stock restore​
IF YOU WANT TO USE THIS GUIDE WAIT UNTIL I HAVE THE LGUP METHOD UP
Who can benefit from this?
Anyone who softbricked with access to download mode [KDZ RECOMMENDED]
Anyone who wants to use the OTA function after root [TWRP RECOMMENDED]
Anyone who needs to send the phone in for repair [TOT RECOMMENDED]
Anyone who wants to be on the most recent firmware [TWRP RECOMMENDED]
Anyone who wants to downgrade *After you update to 20B it is recommended to not downgrade. If you do you WILL have connection problems
Anyone who wants to return to stock from aosp or aokp
Tip: Most of the time TWRP will do what you need without the troubles and baggage TOT and KDZ bring. It will downgrade, upgrade, root, fix soft bricks or just give you a fresh untouched operating system (no personal data left on the phone if you follow instructions). It will also get rid of any proof on the phone that you were rooted (my t-mobile reports root to a remote server nothing can be done about that).
Strengthens and weaknesses for each method click here
TWRP Files/flashing guide Most recent = D85130g_00_0420 (07/05/17)
(This is a WIP)
Download your preferred choice of D851xxx-Untouched_Stock_Restore.zip HERE (Perfect 1:1 image unlike most roms)
Also download and copy superSu & twrp to your external sd if you want root and custom recovery SUPERSU DOWNLOAD AND TWRP-2.8.6.0-d851.zip
Copy D851xxx-Untouched_Stock_Restore.zip to phone (external sd if available)
Reboot into twrp
For firmware update do not wipe! skip to step 8. If you want untouched stock continue with step 4.
If upgrading from kitkat to lollipop wipe system before flashing.
Click [Wipe]
Click [Advanced Wipe] (For full wipe stock restore only)
Select dalvik cache, system, Data, Internal storage (only if you use external for downloaded file) and cache
Click the home Icon in the bottom left
Click [Install]
Select D851xxx-Untouched_Stock_Restore.zip (make sure you select the proper sd card)
If you want root and/or twrp add UPDATE-SuperSU-v2.37.zip to the queue by touching [Add More Zips]
Repeat for TWRP-2.8.6.0-d851.zip
Swipe to install [====>]
Install will now begin, pure stock: system, kernel, recovery, modem and rpm will be installed
After completion click [wipe cache/dalvik] (do not skip especially if you dirty flashed)
Swipe to wipe [====>]
Click [back]
Click [reboot system] (it might say no os but it is wrong you do have a os click restart anyway) [dirty flash will not have that problem]
If your sending for repair or jump do a factory reset with what should now be the stock recovery just to be safe.
DO NOT INSTALL ROOT UNLESS YOU WANT IT TO BE ROOTED

After its done sending the firmware over your phone will reboot into mini os and you will see a blue screen with a big 2 wait until you see a big 3 then unplug the phone and close the lgflashtool program. Your phone might automatically reboot on 3 but it hasn't for me If it doesn't just pull the battery put it back in then power up. After one of the updates this step may be different then described. If you have problems just ask and myself or somebody else will be able to help.

Correct it also gives developers a chance to start making stock roms even though we don't have root or a recovery yet.

thanks OP.

thanks for this OP.
now since TWRP was released for the t-mobile g3, soon enough this kdz package will be converted to a TWRP compatible flash package

TYVM, it worked like a charm.

Thanks for the guide ! Will definitely come in handy

Ok now I'm not sure if im reading this correctly but it says in OP to Download one of the KDZ files from the beginning of the post and extract it in the Flashtool folder from his thread, now when i got o his thread I only see the G2 files not the G3? someone maybe point me to the one i need for the D851?
EDIT: never mind im an idioto! disregard

what operating system are you on?

Great guide! Just what I was looking for. 2 questions though... Will this unroot your device? (I would presume untouched stock means that, but you know what happens when I presume. I make a pres of you and me). (I'm looking for a reliable to way to uproot, just in case I want to get an OTA). Also, could you link to the G3 drivers in the OP? This is gonna be my go to post if anyone asks me about it...

Worked for me on 8.1 so it should work for you. Install Microsoft c++ runtime 2012 or 2013 then try again. Also make sure you have the proper drivers installed. Ill upload both runtime and drivers when i get home so if you cant find them check back around 6 or 7.
*Edit
Also make sure your running as administrator.

It will unroot you and it already saved my butt after I accidentaly formatted most of the partitions on the phone. I plan on uploading the unified lg drivers tonight along with c++ runtime. Im also going to hunt down a nice guide and link to it for flashing via the lg suite if this fails. The lg suite way is a pain in the a** but should work if this one fails.

UPDATE
1- I downloaded 2013 Runtime 2013 from here: http://www.microsoft.com/en-us/download/details.aspx?id=40784
2- Rebooted my PC
3- Followed the instructions in OP, performing the CSE flash.
4- Received a timeout error really quick but it started to flash.
5- Around 80% the phone went black and never booted to the LG screen, after it hit 100% I unplugged it, removed the battery and rebooted it.
Booting up it entered some mode for a split second and rebooted itself.
Once on homescreen, it rebooted itself one last time.
I'm UnRooted now
I guess i needed to install C++ Runtime
Thanks

Need help bad

Super long story short. Didn't backup EFS.. I can't wipe phone with KDZ not sure whyvalwya sfails
Anyway no matter what ROM I use modem sucks keeps dropping signal and freezes a bit. I have tried flashing c/m/r/b modems and either they don't work or random disconnected
I need this fixed....and last time I flashed stock B that did work modem was as fast as 3G

quick question with kdz are you plugging the usb cable in a USB 3.0 connection? I know that causes issues

Yeah I am just wondering since you said KDZ failed for you. Switching to the usb 2.0 might fix your KDZ fails. KDZ with the 20b to stock lollipop, then root it and get twrp. Then flash Blisspop and that should fix your modem issues where you don't get 4g lte or 4g lte is not sticking. From there you can flash what ever rom you want. So after a successful KDZ flash just follow my instructions here:
http://forum.xda-developers.com/tmobile-lg-g3/help/lte-lollipop-issue-fix-t3075637

I'll try your method is there a Linux way to KDZ? I tried KDZ on every USB port two different windows 7 installations. Tot works never KDZ
Also I super appreciate you helping me lol I'm about to run over phone with suv

Unfortunately I do not know a Linux version for KDZ. When you are using the LG flash tool you did install the drivers correctly and have usb debugging on and all that? Plus make sure your computer recognizes your phone and you are able to access it via mtp, where you are able to access the internal sd and your external sd card from your computer. If that works, then shut down phone, hold the volume up button while plugging in the usb cable to a 2.0 port. Once in download mode your computer should be installing another driver too access the phone via download mode. That is my experience with the LG flash tool and it works every time, and since I experience that LTE issue I used the KDZ method a lot of times and never failed. By the way, what is the error message you get on the LG Flash tool when you flash KDZ?
FYI.
If you want since you already have TWRP and Root just flash the Blisspop rom and flash the stock 20b stock image from my thread. Just ignore the KDZ or use TOT first then root it and get TWRP and flash blisspop, but either way try to flash the Blisspop 2.3 rom from April 4, 2015 and see if that works

Well the download mode should install the drivers automatically there is no extra drivers, but flash the Blisspop 2.3 rom and I really hope that should solve the issue

Hmm that is wierd flashing the Blisspop rom and have it crash. Never came across anyone with that issue yet. When you flash Blisspop did you wipe everything beside the external SD card in Twrp before installing the rom?

So i KDZ R back on because B was **** lol any way no network but after 3/4 restarts from rooting it was on, then off lol so i set to 2g changed APN and now seems working great
so far zero drops or freezes, Flashed Prime Tether and will test through the night.
I beleive flashing the bliss pop did the trick

Are you getting LTE service on R? I could not get LTE back on R once I went to 20b but never rooted or flashed Blisspop.

Flash the blisspop rom and it should fix the lte issue. Just remember to back up your current rom via twrp. Then flash the blisspop rom, once confirmed 4g lte is stable restore backup and you should be good to go with no hassle of setting up new phone.

1) If you have ADB, connect, allow adb and adb reboot recovery
2) Hardware key combo: Volume Up & Power until LG screen appears, then Volume Down twice, then Power (yeah, looks like game cheat code but it really works)

I thought I had the drivers loaded because I could see my phone in explorer but I must not have the drivers loaded.now how can I find the adb drivers and how do I set them up? Every time I think I am getting somewhere I get thrown way back again. All I want to do at this time is reload the firmware so I can access the ext sd card witch was lost while trying to root and install cwm. I am about to throw this **** aginest the wall wall that way this will be fixed for good.

Use LGUnifiedDriver, it should install both adb and LG drivers

Where can I get a clean download of it? I am running windows 8.1 . I do have a pc with windows xp as well just havent used it in a while.

LG's support site I think, I still use old version, from first time I've flashed something via LGFlashTools.. You can download that and LG Support Tool from there too.

I have the lg support tool installed as well as the lg pc suite and lg flash tool. I will give it a shot using the lgunifidedriver. I wonder when I origanly tring to root and install cwm and then lost the ability to access the ext sd and not being able to boot into recovery. Could it have made my phone not recognizably? I can see the phone in win explorer when plugged in. The pc does not recognize it in device manager. It says it has no drivers.
Other than that the phone works normal (makes calls,receives calls,and such.).

That sounds like Windows problem more. You don't have any of those all-in-one driver packs for Android devices installed? How did you root it?

Well I read to use lg support tools to install drivers then used geefree app to root checked with root checker witch said it was rooted ok then used gprorecovery.apk to put cwm on it. Witch said it installed sussfully. After I had it done I noticed I could not access the ext sd card nor boot into cwm. I read on anouther android forum about a felle who had the same issues and someone said the geefree app caused the issues with the ext sd and not booting into recovery.the phone all works fine except for the issues. I figured if I could return back to stock 4.4.2 witch it is on now it should be back to stock and I could try again from the beginning. I also read something about not using a 3.0 usb in windows 8.1 to use a 2.0 usb port. I'll have to see what usb port is what on my laptop. I hope this is all making sense.

Return it back to Jellybean if possible, use old Jellybean root metod available in the forums, install Freegee and flash TWRP from there, and later update it to newer TWRP on forums. Freegee is a step you can't avoid because it's the only way we can unlock our phones (that I know), and their TWRP doesn't support SDCard (not sure about CWM, but I think it also had that problem, it was long time ago I've used it). E980 can get a bit shady, but it's a great phone, so don't lose your patience yet.

Thanks for the info. I belive I have the drivers installed now, I can see the phone in the device manager of windows and it looks to be good. I will keep you informed as to how it go's.
