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.
Hello,
I tried updating my phone a Samsung Galaxy S5830 with a s5830i OS and I'm afraid I may have broke the phone completely.
I can't power on the phone and power+home+volume up/down all fail.
With Odin3 v1.85 and v4.38 it doesn't detect the phone under COM port mapping. I tried loading it asone package and splitting it into PDA, MODEM and CSC files but nothing works.
It has been suggested that I get a file with it split already by someone else and I'm wondering does anyone have something like this as I see nothing like this elsewhere.
I tried it before and it was being detected so I suspect perhaps the phone is dead now. It doesn't react when it's plugged in so I'm hoping to get someone with the same handset to get the battery charged but I'm not confident.
If people have other suggestions let me know.
Hey guys, My Samsung Galaxy Tab 3 10.1 (Wifi) Won't turn on anymore. Don't even charge! My brother was playing minecraft until my Tablet's life reach 0% (Died). Then I charged it, It's still charging after 30 mins of charging I turned it on then the SAMSUNG GALAXY TAB 3 logo appear (Start-Up) but it fails like it shutted down. I tried charging it again but it wont charge anymore nor turn on, I'm not using any ROM but i rooted my SGT 3 10.1
Anyone knows how to fix this? Please help asap!

Okay, Gonna try those now and hope something will fixed this. I'll reply if it works or not soon
Edit :
Be right back in 2 hours to check everything.
Edit Again :
My Tablet is fixed now, Thanks dude.
What I did is stopped charging for 10 minutes then i charged it using PC/Laptop then waited 1 hour, then charge it on normal then it started to charge and turned on. but again, stuck on SAMSUNG GALAXY TAB 3 logo then shut down....
None of those works. Any other idea?
I would do the process over again. But do not start the tablet. See if you can get into recovery mode (Vol+ / Power) or download mode (Vol- / Power). If that is successful then leave it there for awhile. Power off and try again. If good, then I would reload the OEM Rom or a backup that you may have. But I would not try powering the unit again. There might be a corrupt file caused by the initial improper shutdown.
It got even Worse, I tried to do the process again but it DOESNT turn on or Charge anymore. I waited 1 hour then charge, still, charge 2 hours, still. What to do now? Theres no helper here on our village except me so please help me
If your device is not charging then I wonder if it is the charger and not the device. I don't think the battery could go bad that fast. I could be wrong, but I don't think. So that leads me to believe that your charger possibly is not working like Ripshock mentioned.
Is the charger the OEM that came with the Tablet?
If not, can it produce 5vdc @ 2 amps?
What about the USB cable, is it OEM that came with the Tablet?
If not, is it wired correctly and can it handle 2 amps?
Regardless of how you answered the questions, I would seek another source for charging. I don't think the PC will charge. I don't believe the USP ports are setup to handle that much current. I could be wrong, but again, you might seek out another source for charging.
UPC won't charge tab. It has to be plugged into an eletrical outlet

As I suspected, but I thought I read somewhere that the PC can be setup to do just that on the USB port. Key phrase is "thought I read".
Nah. For some reason the tablet can't charge and transmit data through the cable at the same time unlike our phones and other devices. Personally i think it's stupid that it won't charge but hey that's how they were made lol. I use a very good cable too.

Well, I have been to this situation more than once (Galaxy Tab 3 10.1 and Galaxy Tab 2 7.0, which are both family tablets). Do a "force boot"
Steps:
1.) Leave it there for, like, 4 hours or while it is charging do step 2.
2.) Now, press the power, volume up, volume down and home button together, until the it boots up completely
3.) Charge the tablet again..
Easy as that.. If that does not work, remove the battery inside (You need to have proper tools and a hand that can search youtube)
or, even if that does not work, your brother may have screwed something up (Either by dirty flashing another ROM or by doing some dangerous system modifications).. Your last hope is the repair shop (If you have warranty, send it back to a SAMSUNG REPAIR SHOP and act dumb, they will fix it for you, free of charge.)
I am not 100% sure here, but I don't think pressing the home key while using the power and vol keys will do anything. I believe that to be a process found on some of the other Samsung devices, but not the P5210. I personally have not tried it and I really don't want too knowing right now that my machine is working just fine. Would hate to do something that I cannot reverse.

Yep, I did those steps. and it's turning on now. but i cant start it up. When I open it, it goes to TWRP mode. This happens when I wipe all my phone cache,dalvik,etc (everything) then when i restarted the system it says "no OS installed, still continue?" I choose yes, then it said "your tablet's root could be corrupted, want to install a fresh new one?" I choose yes then my tablet restarts but on TWRP again, I install a rom named Pimpdroid then restarted the tablet, still the same (Always go to TWRP mode even i'm not press power+up volume+home bottom together) Just the power button but it goes to TWRP mode, i tried installing other roms but its still the same. If you can't understand properly due to my poor english. I can make a video on it if u r willing to help me. I really need help guys since theres no repair shop here its just an island!
Does anyone experienced this problem already? or does anyone knows how to fix this problem? Help me please

When it asked to reinstall the root, say NO. Then power off the unit. Do not try and run the tab at this time. There is no OS. Start the tab in download mode. Connect to PC and start ODIN. Load the OEM Rom. This is the only way to get things back to normal unless you have saved a backup. If you have a back up, then start the tab in recovery mode (TWRP/CWM) and restore from backup.
I would recommend NOT installing Pimpdroid or any other rom until you have a fully operational tablet again. Best to always start from a fresh OEM Rom.
What is OEM Rom? and where can I download it?
OEM = Original Equipment Manufacture
OEM Rom is the firmware that was developed by Samsung and is the only official Rom for your device. All the other roms that are developed here are done so with caveats placed on them. Mainly that the roms can damage your device or brick it (cause it to fail completely).
Original firmware (OEM Rom) can be found here. In the search window just enter the model number of the device you have. In this case that would be P5210. It will take several hours to download the rom as it is huge, on the order of 1.9GB. Just be patient. It is always a good idea to have the OEM Rom safely tucked away on you computer for situations like this.

It's just like a rom? after downloading ill just install it like other roms?
and, Which country firmware should I download? There are tons of Country but the same rom
You will download the version for your country. I have no information about your whereabout. So you will have to find the rom for your country or region of the world.
You will need to extract the MD5 file from the zip and place it on your computer. Once extracted, you will open ODIN and load the MD5 file into the PDA slot and upload it to your device. Don't worry about the SS_DLL file. It will take some time to load into ODIN and then some time to load into your device. Do not stop the upload or interrupt. Once loaded, you will then restart your device and configure it like it was brand new out of the box.
The standard recovery will be loaded also. If you desire to load TWRP or CWM, you can if you want. You can also root the device. But I would not recommend loading any of the other roms until you get a better understand of what that rom does and how to load it. There are many posts on XDA that tell you how to load an OEM (stock) Rom. Just do a search for them. No need to be redundant here.
Just be careful.

Well, This is pretty weird. There's no Philippines (Which is my country) OEM rom and on the Tablet, it wont go to Recovery mode or Download mode. because when I charge my tablet it automatically opens then go to TWRP. When i turned it off it goes to normal charging. Then when I try to open it using this (Power button+volume up+ Home) it still goes to TWRP mode. How to fix this?
Before posting I tried looking through every thread after I searched for this but it seems that there was always TWRP to fall back on.
Here's my problem thus far. Rooted my G Pad on Lollipop successfully. Followed this guide after rooting, to install TWRP recovery.
http://forum.xda-developers.com/lg-g-pad-83/general/vk810-altev-complete-root-recovery-t3108260
Followed the first step to downgrade the aboot to 4.2.2, then restarted the tablet like an idiot as I glanced at the wrong browser tab with a different tutorial open. I did NOT follow the second portion of the tutorial to get TWRP even installed and I'm sitting here with the Secure Booting Error in the top left corner. Cannot access download mode, factory reset, normal reboot or safe boot without getting that error. Any help here at all or is this the first time I'm SOL with a device.
UPDATE!
Managed to actually get it into download mode after 20+ tries of just rebooting and trying. Will update if I can successfully reflash with LG Flash Tool or not.
You should be able to flash it no problem since you're in Download mode. FYI, although it doesn't work all the time, someone in my ROM thread found a way to flash aboot (for instance, to flash the Lollipop aboot so you could get back into the ROM) from Fastboot mode. That is, they found a way that sometimes works to get into Fastboot mode.
Also, there's a chance you could perform the required steps to get TWRP installed via ADB with the tablet in Download mode. Not sure, though, since I haven't tried it.
I can certainly experiment, now that I've realized I can fall back on download mode if things go wrong. Flashed the Lollipop KDZ with no problem in download mode so at least the tablet is up and running to take another crack at. Thanks a ton for actually having those KDZ's so readily available being linked in your signature.

Ended up just downgrading to 4.2.2, using towelroot, and loki_flash\twrp. Enjoying CM12 now. Will probably update the original post with instructions in case someone makes the same mistake as me for some reason.
I'm Having the Same Issue
I cannot get download mode to work. Just the Lg symbol, and secure booting error in top left.
I charged it overnight, plugged into a wall, with it off.
Held both vol keys while off, and plugged into cpu using the original/undamaged cable. Tried a different cable that also works, and tried plugging it into the computer both ways (OFF and plugged in the computer first, then the tab, and vice versa.)
Was there any other trick you had getting into DL mode???
Any help is appreciated.
UPDATE: So i left the tablet plugged in, and just kept rebooting it, and held just power and vol up, and now, in a barely visible screen, it says download mode, but my computer thinks there's nothing connected. With 2 different cables, and 2 different flash tools saying this, even with correct drivers installed.

Hi, glad you at least found out the right button combo for Download mode. Can you be specific about the drivers you installed? Were they "LG_VZW_United_WHQL_v2.22.0.exe"?
Try rebooting after installing the drivers, with the tablet unplugged from the PC. After the reboot is finished, put the tablet in download mode and plug it into the PC. It can take up to 10 minutes to load the drivers once you plug it in. Use a USB 2.0 port preferably. Of the two cables you tried did you use the original cable? That's preferred, also.
You can look in Device Manager in Windows and see if the driver is still loading for the Android device listed under the "Modem" section. If after 10 minutes it still hasn't loaded the driver, try a different USB port. Lastly, if you need to, try a different PC. I know it's possible you don't have easy access to a different one, but sometimes that's the solution.
Accidentally my phone droped on the floor after that it kepps the mi logo loop after some time the battery got dead and phone also not charging. While connecting to the charger cable the led blinking and looping. Buy my phone doesn't charging and while on the flash process without battery the fastboot mode opens and closes rythmically.and my computer doesn't take the time to load the drivers. Now what to do feeling dizzy....
Please help me out of this problem. I think it bricked but not hard. Because the fastboot logo comes but not more than 5 seconds it goes off. Please help
Try giving it to a local repair store.
I also had the same problem. If I used to remove and put the battery back, it used to reboot. I tried flashing using fastboot, but it used to reboot every 6 seconds. According to some friends of mine (Thanks to them) I gave it to a store, which in turn (I dunno how) hardbricked the device. I connected it to the PC, tried to go to fastboot, and it shows up as QCOM Loader 9008, which basically tells you your device is hardbricked.
Fastboot didn't work.
Using MiFlash Tool, while flashing through the QcomLoader, it showed "Did not receive hello packet"
Tried many times more, didn't work out.
So, I went and tried the trusted method: TEST POINT method.
It worked out. Now my armani is up and running!
TL : DR;
Try giving it to a local repair store (not Mi service center, they didn't help me AT ALL.)
Something might have dislodged.
Or
Try testpoint method, google for it
it *might* work. Well, that worked for me.
Not end at all
Hi, sorry for very late reply
Recently I discovered that the battery is dead not working at all. And while doing the test point method I think battery power is needed! So I ordered a spare battery after the delivery I will do the test point method agian. Currently if I plug in my phone thorough usb to my computer the qcom 9008 port shows but while flashing it gets detached then re shows up . And the flashtool error happens. I think a battery power is required so that this failure is happening.
So, what do you think is edl mode requires battery power?.
Need help because I have to fix it. It's my one and only loved phone of all time.
Currently I am using my friends phone to discuss about this matter.....please help me.....

You do not need battery power for test point method.
