Can't get into Download-Mode! Please help me flashing..

Hi!
I just can't get into the download-mode.. i tried it hundred times! Its always just booting like normal!
I want to flash the I9000XWJM5 Firmware and then the SamSet V1.9. But i just cant get the download-mode working! So i can't flash anything...
Is there an other way to get into that mode? Or is it possible to flash the I9000XWJM5 ROM in the recovery mode?
Thanks for your help! =)

adb reboot download not working?

now my Galaxy stucks at the black/white Samsung writing! None of the button-combinations work! And it is not recognized by my PC!
What can I do now? Did I brick my phone?!?!

Remove battery for 30 sec, press volume down + menu + power for more than 6 seconds (till the screen comes up). Should work than.
What provider are you on? Cos some phones from Bell dont go into download mode from what I heard.

i'm afraid so
if you can not do the 3 button combination to get it back into the download mode, you'll have to return it to samsung which will refer you back to the phone company to have it fixed

nothing helped... this sucks! those kutton-combinations did not work at all.. even before i obviously bricked my phone.. dammit!
Anyone got an other idea?

at this point there is no much to do but throw in the tower, and take it back to the place where you bough it.
tell them the 3 button restore mode doesn't work, and you can't continue upgrading to version 2.2

I had the same issue

Thanks in advance
EDIT: I just turned if off. Still scared my beautiful phone will break!!!

[Q] Uhhh Crap... Need some help asap guys

Really messed up when i tried to root my phone with THE SAMSUNG GALAXY S3 TOOLKIT [SNAPDRAGON EDITION]. I'm sure i followed all of the directions to the letter but at the end of the flash my phone rebooted into a "soft brick"(Black screen and solid blue led) .Hindsight is truly my ex and I just know i should've flashed cwm before attempting the root. Any help would be greatly appreciated. Please dont tell me i effed up my christmas present before i could even put a new rom on it..
Edit: Using the toolkit I can still get into download mode, and (I think) I flashed cmw onto my phone. Although Im unable to enter cmw manually and I can only enter cmw by rebooting the phone through the toolkit.

If you still see lights opened like an LED then you arn't hard bricked which means there's still a way out.

ODIN! thats might help you out bro

Don't worry, the same thing happened to me when I used that tool to root my phone. First off, don't freak out, its fixable. If you turn your phone off, then press and hold Power + Volume Down + Home, you should be able to get into download mode. If you do, just use this to flash a rooted version of stock onto the phone and go from there. If it won't go to download mode for some reason, come back here and let us know and we can go from there.

Nasty Bootloop after Flash on Sprint G2

Last night I installed geefree on my phone from the app store and used it to install TWRP. I downloaded a nightly CM11 and an appropriate gapps. Using geefree I rebooted to recovery (never figured out the button combination to boot to recovery "naturally") and installed both of the zips. This could be where I made my mistake, I installed both at the same time.
Now my phone loops, displaying the LG logo for a few seconds, then shutting off and rebooting before repeating the process. I can't seem to get it to go into download mode or the recovery menu. I've tried power+up, power+down, down+up and each of those while plugging the device in, etc. I can get the device to a hardware key control mode, though it doesn't seem too useful.
How can I save my phone? This forum has been a great resource in the past and I'm very grateful for the many tutorials I've followed rooting other devices. Hopefully you guys can save the day once again!

Volume up plus power is how to access recovery on sprint.
What stock sw version were you on before you flashed cm?
Did you wipe data before flashing?
Sent from my LG-LS970 using xda app-developers app

I was using stock 4.2.2, I believe. I didn't wipe the data (shame on me), a bad habit that I picked up from my first rooted device, the Samsung Moment. It didn't ever matter on that one, afaik. Thanks for the reply!
Edit: Volume up and power whether plugged in or not takes me to the hardware key control mode screen.
Second Edit: http://forum.xda-developers.com/showthread.php?t=2432476&page=35 I also found this thread where someone seems to be experiencing similar issues and they fix it with "LG Utility." Is that a PC application? It's a little vague to google, but I've been trying!

I have a bootloop issue every time i flash a rom i have to wipe all but sd flash roms and gapps the i do a restore from twrp and oly restore my boot image only and they boot no prob

I'm kind of starting to suspect my power button doesn't work at all for whatever reason. I have a lot of difficulty getting the phone to shut down, then it doesn't seem to easily power up. It's a strange collection of problems. Would a Sprint repair place be able to fix this?

If they have parts on hand if not either a swap out or a sendoff

Same problem here - bootloop and no download mode - CWM works! - urgently need help
I guess I have the same problem as InlineFourPower (apart from that my power-button has no problem).
I am stuck in bootloop since I tried to upgrade to Kitkat a few days ago. Now I can´t get into download mode any more, nor into fastboot or anything else. Only CWM works.
From within CWM I can successfully flash ROMs but that doesn´t help, since afterwards I am still stuck in bootloop. It is possible, however, to push files via adb-commands while I am in CWM.
Does anybody have an idea how to go from here or how to get download-mode back?

Device is recognized but can´t be mounted - bricked forever?

I tried a few things on Linux.
After terminal-command "ls /dev/sd*" when the device is unplugged from the computer I get "/dev/sda".
When the device is connected via USB, I get: "/dev/sda /dev/sdb"
So sdb is my LG G2.
So I went on to the next command: "gdisk -l /dev/sdb"
As a result I get: "Problem opening /dev/sdb for reading! Error is 123."
Does it mean that the phone isn´t mounted or what? Now I´ve connected my phone to another Linux machine with the same result. It is recognised (p.e. as sdd), but there is no sdd1. Seems as if it is recognized, but can´t be mounted. Does that mean my device is bricked for good? That´s it?

to get the phone into download mode you have to plug the usb cord in and hold VOL+, so to get this right as I have a case on mine, plug the usb into the phone first then hold VOL+ and plug into usb port on the computer.
it does take a loooong time to power down the phone with the button when stuck in a boot loop, just keep holding it until it shuts off, it will shut off eventually!!
plug the phone in while in download mode to install drivers and set com ports, then unplug before you begin your flash with LGFlashTool, hope this helps you out.

Thanks Cronic2009 for your advice.
There are, however, szenarios where download-mode is not accessible any more. Neither by using the hardware-keys, nor by using the adb-command.
After four days of resarch and a lot of trial and error, I finally unbricked my F320L using the two adb-commands outlined at the beginning of that thread: http://forum.xda-developers.com/showthread.php?t=2451696
Worked like a charm.
Thanks everyone for your advice.

no problem buddy, glad you got it figured out, good luck to you from here on out!
FYI, that link doesn't work
I just wanted to ask anyone who might know, since the bootloader of the LS980 is locked, we cannot "break" this correct, so no matter what commands we decide to run through root, we cant touch the true bootloader there for LS980 fail safe? (Besides Acts of God, EMP, ect)

Thanks for letting me know. I corrected the link in my previous post.

Be sure if you use a aosp based rom to flash the ZV8 modem. Your can use dr87 or furnance kernals after you flash the zva modem althought i have encountered soft brick due to this.

After using tot and flash tool to get back to stock, did you try going into stock recovery and do a factory data reset? I know it sounds stupid especially after a tot but try it. Couldn't hurt

Borderline noob here, so please bear with me...
I have been using TWRP 2.7.0.0 to do all my work, and I was able to get the Lego ROM installed with ZVA. I got into too big of a hurry and forgot to make a backup of stock. I've also been unsuccessful in trying to install ZVC modem and firmware. Thankfully ZVA works as does the LEGO ROM, but I'd like to have stock there to access as well. The stockZVC that's on the Android Development page has been getting stuck (bootloop?) on the Sprint Spark logo. I've done TWRP's factory reset with no success. Any help would be great.
Thanks in advance!

Yes sir I've tried that and more to no avail is there anything I can do through adb I'm on stock recovery phone doesn't stay on long enough to install anything

[Q] :( HEEEEEELP! STUCK AT LG LOGO WHEN I TRY TO BOOT! But wait, there's more......

I have spent the last 3 days searching XDA & trying every possible fix, no luck!
Here's my dilemma.....
I have custom recovery, TWRP 2.6.3.3, don't know what I did after trying to flash something........ I wiped everything except SDcard by accident. Like a darn fool, forgot after backing up everything via computer, to put a spares on my SDcard. Sooooo, I tried restoring by using LG FlashTool..... Here's where my problems began:
1. I can't load into download mode, it sticks at the logo to enter download mode but doesn't connect.
2. I tried ADB Sideload, sticks at "STARTING ADB SIDELOAD FEATURE.........."
3. No matter what mode (including Fastboot) I try, just won't connect to my computer the way I need it to. (*ALL DRIVERS HAVE BEEN REINSTALLED NUMEROUS TIMES, STILL NO LUCK.*) When I look in DEVICE MANAGER, it shows in "OTHER DEVICES" as "LG-LS980" (*Which is a good thing right? *)
At this point i'm at my wits end...... I tried to HARD FACTORY RESET, but didn't go thru. I'm afraid that if I tried it again, I could cause even more damage.
I've been without my phone for days & I'm about to go crazy if I have to pay LG or Sprint again for another phone!!!! I'd rather use my $600 on something else.
PLEASE TELL ME SOMEONE HAS FOUND A WAY TO GET AROUND THIS!
I've searched just about every forum & tried different methods.

Forgot to add that every time I power off from recovery, I get a the message about my device not being rooted, would I like to install..... When I swipe to install, nothing happens. Just powers off.

So try this...
Push the power button to turn the device on. Let it sit.
After you know that the g2 is on and trying to do its think, Press and hold power buttton, do not let go. It will force turn off the phone, but it will start to turn back on, if you keep holding the power button till it shuts off for the second time, you'll be set and the device will be fully off.
Have Lg Flash Tool open, make sure you have manual mode on and you point to the right dll and right tot file, could be zv7 zv8 or zva.
Click the arrow to have the flash tool biin check the files. when that is ready, do this next part fast. Plug in your phone, and immeditaly press and hold Volume up and Power. Download mode should appear.
and you should be good from there! If you try to enter download mode by using volume and up without the cable plug in, you'll hit the factory reset menu which is tied to the recovery, it'll do nothing, only take you to recovery. I hope this is of some help!

Edit:try new boot loader or system flasher via twrp
proplem i faced is one button which used to enter recovery is damged
Flash stock Ignoring the unmonted ianot able to be mounted then change system partitions u will be able to mount
Enjoy

Ok... So i made a little progress....
I am now able to boot into fastboot mode.... No recovery now tho. If someone can help me with manually pushing everything I need to restore my phone, it would make my day!
I'm having withdrawal symptoms now. LOL! I MISS MY PHONE!

Problem solved!
Flashed all the partitions 1by1 via fastboot, was able to then reboot into download mode. Now using LG FlashTool to return to stock! I am now a very happy camper after a week w/o my phone!

After she got it the first time, which we both congratulated her for, something went completely wrong. She dug herself even deeper, but broke download mode. That was extremely fun to fix.

Bricked d855 16 GB No download mode

Hey All,
I have searched the forum for this but i dont seem to get the same issue. And i dont want to make things worse, so i post it here. Hope you guys and galls are able to help.
So what happend. I wanted to flash back my G3 d855 16Gb Eur model.
Something allong the way went wrong, and i dont know what. All i know is that when i came back my phone was turned of. And my pc gave a failed message.
Now i cannot get in to download mode anymore. It gives me the LG boot logo and that is it.
When i want to enter download mode i get the download mode logo, with in the top left corner a verification error.
It goes quite fast so i cannot get the exact message. Can anyone point me in the direction of a fix. Ore is it indeed really dead?

Hello and thank you for using Q/A,
if you can't enter the download-mode, your mobile is dead. You may flashed a wrong firmware and the bootloader was overwritten with a wrong device.
Can you enter into Recovery?
Kind regards
Trafalgar Square

Nope, the phone reacts when i connect it to the pc. I get the android bootlogo. And when i power up with volume -, the i get the factory reset options but it dont work.

would the wiretrick help me out ?

Can you reboot your phone into recovery mode (If it is already rooted and custom recovery installed).
I also faced a problem like that. In my problem when i reboot into download mode it took me to fastboot mode with 4 to 5 commands on left upper edge. If you can boot into that "fastboot" mode then tell me so i can help you better.
If you can't see anything like above then tell me that too i will try best to help you get out of this problem>>

No I don't get those options.
I get some kind of miss match error
exact error is:
boot verification failed
cause mismatch_sig_len

Hey All,
Just want to let you know, that i have been struggeling with my phone for two weeks. Offcourse not 24/7. But it is back alive. I managed to do the wiretrick and i was able to load up the Qualcom 9008 driver. After a long struggle i even managed to get the phone reconized by board diag. From that on it was easy to flash back all partitions. And download/firmware update mode was back. After this all i was able to flash the KDZ file.
I then lost my IMEI, but i backed up my EFS and all other importend files in the beginning. After rooting and flasing my EFS all was back to normal.
So ... i quess the d855 is indeed unbrickable
