[Q] E988 Cant get in Download mode (no custom recovery)

Hello all, I have a problem with my LG oprimus G pro:
I have updated to official 4.4.2 and it was a bit buggy. So I decided to flash CyanogenMod
So the first thing is to root the phone I did that from here
http://forum.xda-developers.com/showthread.php?t=2695263
post #4 guy named galapagos has roottool.kitkat.zip attached. So I downloaded roottool.kitkat.zip unpacked it to "root" folder
folder tree:
--------root
--root.zip
--adb.exe
--AdbWinApi.dll
--AdbWinUsbApi.dll
--StartRoot.bat
and ran the StartRoot.bat that I found inside.
All it did was reboot the phone to stock recovery waited for me to click install from sideload and it than executed next command:
.\adb.exe sideload root.zip
the phone rebooted, and I installed rootchecker app to test if I had root. The test was positive. cool :laugh:
now I wanted to install CyanogenMod I downloaded the latest build from here http://download.cyanogenmod.org/?device=e980&type=
I renamed the file I downloaded to root.zip placed it in the folder where StartRoot.bat is (replacing the old root.zip) and ran StartRoot.bat once again.
the phone verified the root.zip and started to install it. :angel: In the middle of installation it aborted the installation and rebooted the phone. it will not boot to android system (I wonder why ) instead I am greated with LG security error after witch the phone turns itself off.
I have tried getting into download mode buy key combination= hold volume+ and volume - together and connect usb. It only starts charging.
when I press volume down+ home+power it takes me to factory hard reset. but the reset changes nothing...
do you have any ideas how I can unbrick my phone? Will USB jig work on LG phones?

Manually uninstall and reinstall LG drivers. text me if it works for you.

I got the problem too with my G PRO, that I get a hard time to get into download mode. It always starts the phone. So just be patient, try it more, just remove the battery if the method gets awry. I tried it many times, then it worked.

OR
You can try to plug your phone on the PC, go to cmd within adb, key in adb reboot recovery. Voila.

tried many times the "normal way" and with remove battery way
no luck...
I even tried with live linux usb and still no luck..
I dont know why wold drivers have anything to do with download mode?
if you have e988 you could upload a video on youtube on how to get to download mode DD
I cant seem to find any videos on that for my phone.

I also have the same problem with my F240S, cann't go to download mode, and can't flash this damn Lollipop kdz

Hello everyone, its been a while, thainks to all for trying to help me
In case anyone is wondering, after I realised I couldnt do anything myself, I gave the phone to phone service.
Acctualy, I gave it to couple of services, some of them didnt know what the problem was, and they were unable to Jtag it.
The others said it was the problem with the emmc chip.
the last service I gave it to (as I understand) tried to flash it with firmware? that isnt made for E988.
Now when I power it on the screen is blank and the button led is changing collers.
I have accsepted the fact that the phone is dead

my problem was solved....actually I tried and retried a few times the same technique...press volume up + volume down and plug in usb cable...finally it worked and I flashed the loliipop kdz...many thanks

yea, i was going to say hold down volume + and plug in usb cable to get into download mode. if that doesn't work, it's a world of headache.

it's not just the phone you should check if youre having problems flashing/rooting/going into download mode, you should also check your computer, do a reboot or try reinstalling your mobile drivers and the apps you are going to use.

Help - Stuck on Download Mode

I rooted and flashed Sphinx. The ROM somehow kept me from hearing the other person on the other line when making calls and they couldn't hear me. So I was trying to unroot by using the Flashroot tool method. And now I'm stuck on download mode.
I have a d855. How do I unroot properly and how do I get out of the download mode.
This is my first time rooting an LG phone :/

Hold the power button for 10 secs to reboot to normal. <<<<<<<< Depending on what you have done >>>>>>>>>>
ENSURE that no transfers or other process are in progress or you will have a bad day. I don't know what you have done on your phone but ensure you read the thread you are following completely.
Are you trying to restore to stock? There are a few threads that you need to follow exactly or you will brick your device.

The method failed, so I gave up and wanted to just reboot. Did a batter pull and was able to get to the factory reset screen, but it just loops back to download mode.

follow this, for your variant, it should get you back on track don't forget to check the hashes as a bad download would cause it to fail.

I don't have the links to the tread where I got these from but lets just hope I don't get banned.
1) go to download mode
2) install this and download the correct .kdz file for your phone
-Modelnumber is ...
-serial number is your imei number
- wait until the download is done
3) run the lgflashtool2014.exe from this zip
-Select type= cdma
-phone mode= Diag
-reset time=33000
-Should be like this when You run it
-select kdz file= is where you need to find the kdz file you just downloaded(step 1)
-then press cse flash
-in the now pop-up window select start
-select your language
-ignore error (cannot connect to lg server)
-check progress on phone up to 100% then boots in recovery installs and restarts
-wait untill it goes to the welcom screen then you can unplug
-now the most inportant step Like my post
to enter download mode do this:
--You must switch off the device to start the process.
--Then press and hold the “Volume Up” and connect the USB cable from phone to PC.
--Use the original USB cable. Because, other device’s cable may not be detected in the Computer. So, only we recommend it to use the original-- one that you got it when you bought the phone.
--Wait for the driver installation on PC.
--Then you will get the download mode screen in your phone.
--That’s it.

I have the opposite problem, can't get into download mode haha

I can't find the .kdz file. I have the D85010d.
Also, i ran the original lg firmware, I also get an error saying it was unsuccessful or i may have keyed in something incorrect.
When I run perform the TOT method, I get the "device model is different".
So, d85010d was stock and I flashed sphinx d855... where they incompatible? im assuming no because the phone ran fine aside from the issue i stated on the original post.
would like more help.

Okay, it installed but i'm stuck on the boot screen. Tried to do a factory reset, but it just loops right back to the boot screen.
But the installation completed. Does this mean I'm back to stock though and root is gone??

I tried everything TOT& DLL files KDZ Files no thing work for me.

I have the same problem im stuck in download mode and i cant find the kdz =O
I need to know if something can resolve this problem , my device is a lg g3 850 10 d and i installed the room sphinx for the lg D855 and was incompatible because the dialer did not work properly and try with original tot for my device and dont work with this method.. so i need the ORIGINAL KDZ for the lg G3 D850 10d know where to find???

Hey men you can find the solution of your issue?

I was in your position. Once you enter the download mode it is *almost* impossible to get out without removing the battery. I've heard a lot of suggestions like pressing the power button for 10 or 20 seconds or even doing that in combination with other keys, BUT the ultimate truth is that you have to press and keep holding power button for at least 1 minute. I didn't time exact seconds, but it was ridiculously long time. Probably it will take you less time removing the back and re-sit the battery, but personally I hate removing the back without serious reason
About the second question - I was unable to flash anything in LG's download mode. I'm using Ubuntu + virtualbox (Windows 7 inside), but due to issues with drivers and/or virtualbox and/or usb port forwarding I was unable to reliably connect and flash the stock kdz image. Fortunately I've sent the phone back to the LG repair office and they re-flashed the firmware for me.

It is not exactly what you want, BUT at least you can get your latest, official KDZ file from LG.
Open in browser the following URL, but replace the xxxxxxxxx
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=xxxxxxxx
where xxxxxxxx is your IMEI number
As a result you'll get an XML file that will contain the location of your latest KDZ update, which should look something like this:
http://csmgdl.lgmobile.com/dn/downloader.dev?fileKey=.../D85510L_00.kdz

If you can't get in that, then something very serious happened!
you sure you can't enter it?
Otherwise, it would mean you messed up the bootloader!

Did you fix your phone?

soft bricked
boot looping
when i enter into download mode
flashtool says an error that
*cant change to Download mode*
Download fail
what can i do?

Hi guys, i know it's an old post but i get the same issue.
I was following this tutorial https://linustechtips.com/main/topic/1058206-lg-g3-lineageos-tutorial/
I was on lollipop.
I initially downgraded to kitkat (V10e) using LG UP and then rooted with purple drake.
In the following reboots, "kernel error" occurred.
So I tried to flash the kitkat stock version again but without success.
I'm stuck in download mode and tried to flash both the kitkat version, the lollipop and the marshmallow, through .tot and .kdz, I tried both with LG UP, LG Flash tools v 1.8 and with LG flash Tools 2014 but in all cases unsuccessful because the phone reboots before it ends.
Now I don't know what to try anymore. Do you have any solution, please?
Thanks in advance.

Have you tried the other flash tool? I'm not sure if it will see your phone in the state it is in but if it does it may not require your imei. It can be a pain on win 8 64 but it might work for you http://forum.xda-developers.com/tmobile-lg-g3/general/firmware-t-mobile-lg-g3-t2818667

Is it normal for it to stop at 4% every time?

I know you said you can't get into download mode but maybe try this. I made this guide for when I owned an L9. It worked for my G2 as well. Of course use the kdz for our phone.

Lg makes it damn hard to completely brick a phone. I've seen so many people resurrect their phones from some of the dumbest sh!t you could do. There's a way just have to find it. If the phone's recognized by adb then someone could dump the boot, recovery, downloadmode partions and you could flash them back. You can try all the unbricking guides. There is a way to fix these 99% of the time I promise, just don't give up.

He tried that tool already. Well it was a modified version of uptest that doesn't require all of the extra steps. I was doing some reading and it looks like most lg phones are capable of adb turned off in charging mode so that's a fantastic idea you have about adb. I have the full kdz dump I can upload the second I get home.

If you already installed the drivers before you don't need to install them from the support tool.

(Soft)Bricked LG G4

While installing the latest version (6.0) which I downloaded, I also wiped the system partition.
Now when I turn it on it just stays at "LG Life's Good" and it won't leave that state unless I turn it off.
I can't enter bootloader/fastboot mode nor recovery for TWRP.
Is there anything I can do?
Note: when I try to do the combination for recovery mode I get the message if I want to go back to factory settings, TWRP doesn't come up.

you cant do nothing . just wait as a lot of people on the forum because is not possible yet to use the flashtool . for flash kdz 5.0 or 6.0

its the same issue with a lot of people . you can with flashtool . not need twrp . but for the moment need to wait a update for that

You wiped your /system partition = no OS = so the system can not boot. Not a brick.
The TWRP issue is a bit interesting tough, how did you wipe it? you tried the temporary boot to TWRP via fastboot commands? Or flash it via fastboot again?

you understand nothing ... with the new 6.0 update for the moment a lot of people have a bootloop as issue ... impossible to make a hardreset ... impossible to install twrp ... impossible to use the flashtool saw the flashtool software is not updated yet ... you cant flash the 5.1 or 6.0 for the moment ... there are too much people with this issue on the website ... look all the post*
we have not access at fastboot mode or recovery mode if you prefer . when you use this option ... the hard reset its impossible and that restart the phone and bootloop again and again

Of course I do not understand, when you are trying to tell me that fastboot needs USB debugging, rather than new bootloader is causing issues

Ermmm wait. So you say the G4 does not have a hardware button combo to boot into download/fastboot straight away from a power off state? That is kinda fail from LG.

all people with this issue after have flashed the autoprime zip etc etc have this problem . you have access at download mode but flashtool doesnt work for the moment because imposible to downgrade for 5.1 and imposible to use kdz 6.0 ... the factory reset doesnt work . whn you do it . you have again the bootloop isue . and impossible to have access at the recovery mode . we are more 100 people on xda to have this issue
then yes you have the button cmbo . and you go in factory reset . normaly after you can go in recovery mod but that doesnt work

It doesn't.
And also if you do the combination of volume down and power button for recovery mode, TWRP won't come up.

even you can go into fastboot mode (check this thread: http://forum.xda-developers.com/g4/general/guide-how-to-enter-fastboot-mode-t3239537/post63623844#post63623844) but that won't help unless you have an unlocked bootloader.

I didn't had the same issue as you, but had a similiar one (phone didn't get discovered neither by LGUP nor LG Flash Tool). Yesterday I fixed it by following this guide:
http://forum.xda-developers.com/showthread.php?t=2785089
In particular the part where you change your device to COM41 in the device manager.
After you get it discovered by LG Flash Tool flash an official KDZ.
Reboot the phone and connect it to your Windows, allow the connection from the phone screen.
It should promt you to install drivers on the computer, do that (they are different from LG Drivers you download from the web mind you)
Now you can change your COM port back to 3 and everything should be fully discoverable by both LGUP and LG Flash Tool.

I think I replied to you on reddit (same photo) Have you tried plugging the phone in while in download mode ? Did you try installing drivers from the internet ? Coz thats how I fixed the same problem you have.

You asked for other people's time to help you, but now you don't have time to explain how you made it work?
Yeah... there MIGHT be other people with the same problem, but why would you care to share.
What an as*hole you are. Another typical new buttuser ruining a great dev community.

Exactly, here I am running around in circles over this BOOST Stylo 2, just got it with MM 6.0.1 out of the box 2 days ago. I caught the 454.4mb update it has been trying to do! Got that baby downloaded! 1.02gb unzipped and renamed to kdz. Got a script for Terminal that will replace Kingroot's temp root with SuperSU but I am not going to attempt any further until I know LGUP will recognize and flash my .zip the bas****s deem not worth enough to put up for download on LG's site!
I got LGUP to recognize it in download mode, reads out LGLS775 but still says it cannot open it...............
His info on how he got it to work would prolly have solved this dillema..............
oh well
zach

ok had a LG G3 that's done this- as long as you can get download mode it should recover, YOU need to use the LG mobile support tool from LG website ( LG UP sees phone as unknown model ) run LG mobile Support tool and in option choose UPGRADE RECOVERY . follow instructions and allow to start process, it took 57 minutes to repair my phone - it will seem frozen anywhere from 0% to about 22% JUST WAIT IT OUT!! lg up / twrp flashes in 5 to 10 mins -- the LG m.s.t writes block by block and takes 1 hour +
so hints and info took 3 goes to find and start upgrade recovery - error on a couple of attempts. phone seems frozen around 10% and 15% of firmware upload -- go make a coffee drink it, go pee then come back and worry! A watched pot never boils!....

It didn't. It's EVEN MORE broken :'(

I figured out how to get my PC to recognize my D851. Apparently all the LG software didn't like how many COM ports I have. As soon as I unplugged everything else from my PC, the software worked. In this case, it was LG Flash Tool 2014, but I couldn't get any of them to work before.

Try running LGUP as Admin!!! For me it worked!

Hope someone can help me. I flashed a rom for a d855, d855g30 I think, and although I can access download mode all aps for flashing fail saying it's the wrong model number. Even the generic DLL file cant trick it. It still starts booting the rom but boot loops before entering. I no longer have twrp and when I try to do safe mode or factory reset I get a boot validation error or something similar. Just seem to be stuck. Im using a VS985.

One cause of LGUP "UNKNOWN"
While an old thread, it'll be found in searches. For anybody who gets "UNKNOWN" device with LGUP for the LG G3, I found that LGUP for the G3 is often distributed with the wrong DLL file. See the details here, post #11. After installing LGUP, make sure that the "model" subdirectory in the LGUP program directory is the same number as the processor in your phone, in my case c:\Program Files (x86)\LG Electronics\LGUP\model\8974 (was 8994 with the "LGUP for G3" I downloaded).
