I took my stock AT&T tab and wiped it then flashed Roto JME-4. When I rebooted, I had a black screen for about 60 seconds, with a skinny white line, and I could hear the samsung music. After about 1.5 minutes, I pressed the power key, and screen went totally black - no line. Then I pushed power again, and everything was normal after that, unless I rebooted.
Anyway, here is it fix:
1) go to http://forum.xda-developers.com/showthread.php?t=899196 and download the jj4bootloader.zip file
2) use odin to flash the unzipped jj4 file. It goes in PDA and nothing else in any options.
3) upon reboot, you will have a 100% normal startup with logo and music.
I used the Bootloader Patch app to check this, and it reports it is safe, and that I can flash anything.
Thanks to Roto, Chain Fire, and alexnoalex
Ok, so, just to be sure I'm not going to break my Tab, doing this ONLY changes/fixes the boot animation etc. (get's rid of the AT&T stuff, and puts in the Samsung stuff).
To be clear, I just flashed Roto's latest Euro firmware (Baseband P1000XXJMA, Build FROYO.XXJME), so performing this fix won't affect/change ony of this stuff right?
If I have to re-flash everyting from scratch, then it's really more trouble than it's worth (Blank screen at bootup? Big deal... It's just at boot right? Everything else works perfectly!)
I wish rotohammer and other rom devs would include this information clearly in their initial posts. Took me awhile to find this fix but it works well. This is also important because you can't see the recovery screen without it.

This is just a quick 30 second flash thru odin, it only repairs the black screen, and doesn't touch anything else!
The developers took out the sound and logo to make the rom file size correct.
That's just the answer I was looking for! Thank you good sir!
Glad I could help.
Hello, I have the same problem but I cannot flash the zip file because my computer doesn't detect the tab when I'm in download mode. I tried updating the drivers and software and it still doesn't want to detect it. I cannot get into recovery mode because of the black screen/white line. Do you know what I can do to get my computer to detect my TAB? I tried searching the forum but could not find any info that helped. Any help is much appreciated. Thanks!

Are you using windows xp, or 7? Put the tab in download mode before you connect to the computer. Is your tab set to usb debugging mode?
I used Win XP, Windows 7 x64 and x86, non of them worked. They can detect my Galaxy S I9000 phone but not my TAB. Yes, I tried it with both debugging on and off, it still doesn't work. Could it be the kernal's fault? Maybe the cable? It will charge the TAB but for some reason my computer won't detect it.
Try different usb cables and ports on the computer.
I tried a different wire and usb ports and it's still not working. I just realized the TAB is not charging anymore. It doesn't make the charging sound when I plug it in. Figured out it's not the cable because it worked on another TAB. Could it be the firmware or kernal?
Not charging when plugged in the computer, or in the wall outlet? Plug it in the wall for at least for hours to get a full charge.
It charges if I plug it into the wall but its very slow like when you charge it via usb. Im using the original charger and cable. There is an x next to the charging/lightening icon on the top when I plug it into the wall and computer.
Just let it charge all night. Be sure its off when charging.
What's the point of having it fully charged? How will that help? My computer still won't detect it even if it's fully charged. I need help to get my computer to detect it so I can restore the original firmware.
I have seen five problems like yours, and after a complete charge, then reboot the phone into download mode, the problem cleared up. They used a different usb port also.
Go to windows update and update your pc.
Look a few threads further down named «help help help»
Ok its currently 50% now. Ill let you know once its fully charged. Thanks for your help so far.
Its 100% and my computer still doesn't detect it. Now what?
Did you have a chance to see the thread “help help help"?
This will sound crazy, but double check your cable - recently someone had the same trouble, because they had dust in the cable connector.
I cannot see the thread you're referring to.
Yes, I did tried a different cable and it's still the same.

I'm not that familiar with LG devices (usually messing with Samsung) so hope I didn't just brick this thing. The device is a VK810 and before flashing was rooted w/stock 4.4.2 on it and stock recovery. Installed TWRP, performed wipes of system, data, internal, and format in preparation for new rom. Then flashed this stock rom: http://forum.xda-developers.com/lg-...-stock-rooted-lollipop-rom-int-g-pad-t3079312 and then flashed SuperSU. Rebooted but system never comes up. Nothing. Not boot screen, LG logo, nothing. Device was at 97% battery before flashing and have tried plugging into power cord and holding down combination of buttons. Cannot get into download mode or anything else. When the device is plugged into the PC via USB I hear it connect and when holding the power button it will disconnect and reconnect in a loop. However, the screen is always black.
Tried this also with no luck so far:

Although I didn't try and flash what you did, I wasn't able to put mine into Download mode to recover it either and only received a black screen! Turned out it was just ridiculously low on charge. I knew it was 'working' because with a USB cable in to the PC and holding the power button on the tab it was making connect and disconnect noises. Your best bet is to plug it into the mains charger and hold the power and/or power + vol down (I'm not sure what worked, I did a combination) until you get an LG logo. when you get to that, let it charge fully. (You should see the battery logo on screen)
Shouldn't have a problem once it's fully charged.

So is this tablet a brick now or is there a way to recovery? Not sure how just flashing a rom/kernel bricks a tablet and prevents the screen from coming on. The bootloader did not get updated or messed with as far as I know.
Hi. Sorry to say but you flashed a ROM for the V500 international variant of the G Pad 8.3, which is incompatible work the VK810.4G variant. There's a third variant, the V510 as well.
Even if the screen is blank does the PC indicate the right entry in the tablet in the Modem section, if you go through the motions of putting the tablet in Download mode, which are to have the original USB cable into USB 2.0 port, with the tablet completely off (hopefully), press and hold the Up Volume button and while holding it, connect the other end of the USB cable to the tablet. You should be able to let go of the up volume button now.
Then try LG Flash Tool 2014 with the 11A KDZ from my signature. 11A is both easiest to root and to install TWRP. If you get that far you can flash my ROM from my signature, make sure you have TWRP updated to v2.8.7.0 before doing so and follow the directions on the OP of my ROM thread.

Unfortunately pressing any button and plugging in the USB cable shows nothing on the screen. The PC chimes when it is connected and disconnected but that is all. Can't remember if there is a charging light on the tablet but when plugged into the wall charger nothing lights up. If the tablet is plugged into the PC and power button pressed it will chime connect and disconnect in a loop.
I realize now the rom was not for this version but wish someone could tell me how just flashing a rom/kernel combination (with no bootlooder changes) causes the tablet to not even power on. Doesn't make sense. Will probably have to send it in for repair cause it seems I've tried everything.

I haven't downloaded the ROM so I don't know what it contains. Are you sure it doesn't contain a bootloader? Did you look inside the zip to see if there's an aboot.img in it? On the VS985 G3 (and my VK810 ROM which I based on @hsbadr 's JasmineROM), all stock based ROMs contain the proper bootloader.
On @xdabbeb 's VS985 v2.0 ROM, the bootloader is in the bootstack flashable zip and not in the ROM zip, but the instructions are too flash the bootstack zip too.
There's other partitions than the bootloader that would cause a catastrophic issue sick as your experiencing. Why exactly? Can't say other than simply that the ROM contains partitions made for another device, they're incompatible and therefore makes your device not work at all.
I figured your only option would be to have it repaired. You could say it happened while or after using the official LG recovery tool under Windows.
Okay, I went ahead and downloaded the ROM. As you said, it doesn't contain a bootloader but it does have the rpm and tz partitions. According to rpm = elf binary/power management, tz = elf binary/QCom trustzone secure exec[/QUOTE]
I would guess that those two would totally hose being flashed on the wrong device if the kernel doesn't. Just a guess, though.

I see your point but even with the wrong kernel a tablet should charge when turned off. Should be no software running whatsoever to prohibit that.
Anyways, I sent the tablet back to LG for repair. They stated it has a charging issue. Should be getting it back soon and will for sure flash the correct stuff on it this time.

I disagree. When Android devices are off, and you plug them in to charge them, at least for a bit when the battery charging animation loads and runs, something is running, and the files used for that device off battery charging animation are located with the rest of the Android system files.
Cool, hope you have as good experience with their RMA service as I did.
i rooted my us cellular uk410, got in a hurry and installed TWRP zip to the boot image zip slot and never boots. now it's essentially soft bricked. is there any way to recover my tablet?
Does it go into Download mode and do they provide KDZ files for your device?

when I try, it displays the TWRP launcher screen where the LG logo should come up. the screen is unresponsive. I tried using the lg recovery tool. doesn't work. however the tablet does show up on my in my menu and I can get to internal storage.
I cannot turn the tablet off, I have to let it die on it's own. it never goes to sleep either.

I'm sorry mate. If you can't it into Download mode I don't know any other options. You installed the right drivers for your device on Windows? Rebooted the PC after installing the driver (with the tablet disconnected)? Attempt to put the tablet in Download mode - it can take up to 10 minutes for Windows to load the driver every time you try to connect the same device to a different USB 2.0 port. Are you using a USB 2.0 port? Preferably one right off the motherboard and not through a hub? Using the original USB cable?
Those are my last ideas. If it shows up at all it should show up in the Modem or Ports section of Device Manager. If it shows up as QHSUSB_BULK, google that term and you might find a way to recover.
I was able to install CM boot animation, then install CM 12.1 for v410 and so far so good.

Well awesome!
Hello everyone,
I'm new to the forum (so if the thread is in the wrong place, I apologise), but I've been using ROMs and kernels from the forum. So I have a problem with my Nexus 5X. I have been using it with Pure Nexus 7.1.2, EX kernel, and rooted since Pure Nexus 7.1.2 came out. But recently (a month ago or so), the phone disabled itself. I mean, a lot of functions stopped working. That happened after I plugged it into my computer with the original USB C Cable (as I usually do), but this time, the phone shut down and the status LED started blinking red. After I turned it on, things like the recent apps button, the home button (only the back button works), notifications, status bar, developer options, and some gestures don't work (maybe I'm missing something else, but you get the point). Even the USB connection doesn't work anymore and I can't upload a new ROM on the flash. I tried Reset, Hard Reset, backup (system, data, boot) and restore, but with no success.
And I don't even know what could cause such failure. Any suggestions? How can I clean and reinstall if USB doesn't work and I'm not sure about downloads (nothing appears on the notifications when downloading)
Thanks in advance!
Hello,
is TWRP installed on your Nexus 5X?

Yes, it charges, it fast charges too. But it doesn't connect to PC for file transfer.
Okay, did you try fastboot devices in fastboot mode?

Yes, It's detected by fasboot . Maybe I could try a sideload? And then flash a new ROM?
But still... what could have caused this?
