AT&T Tab Black Screen/White Line During Bootup Fixed - Galaxy Tab Android Development

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.

[Q] help please, I think I bricked my phone

Hi everyone, this is my first post, and I'm completely baffled and think I may have bricked my phone. Here is exactly what happened.
I've been running syndicate rom with vision kernel on my samsung epic 4g on sprint for a very long time. I've been getting the upgrade notification for months, so I finally decided it was time to upgrade. Unfortunately, the way I decided to upgrade was to go back to stock, and then let it naturally upgrade. I followed the instructions at:
http://forum.xda-developers.com/showthread.php?t=1052813
and, the first time I tried to odin, it was stuck at "setup connection", so after waiting a very long time, I unplugged, then re-started odin. because I used the instructions at the above link, I had re-partition, auto-reboot, and reset time checked. This time, odin was able to get past "setup connection", and was stuck on "datafs.rfs" in odin, and on the phone, it no longer showed a downloading logo and looked like it was just off. I unplugged again, and this time, I could not easily get the phone into download mode. I tried a few things with the battery in, with it out, and finally, somehow, got it into download mode again. Trying odin 1.61, I tried again, it got stuck on datafs.rfs again, and after waiting a very long time, I unplugged again.
Now, I believe my phone is bricked. The following is true of my phone right now:
it does not turn on
it does not have any lights when plugged in
if plugged in, it will not go into download mode
if on battery, i can take out the battery, then put it back in, then i can go into download mode, but when in this mode, windows reports an unrecognized usb device. if the battery is in from when it was plugged in, it will not go into download mode. the battery must be popped out and then put back in to go into download mode.
terrible timing too, as my wife is expecting, and she'll most likely need to get in touch with me in the next week or two. If anyone can help me get my phone working again, that would be amazing. Thanks in advance for your help.

Windows not recognizing a device means you don't have the proper drivers installed. I'd link them to you but I'm at work on my phone. Search google for samsung epic drivers. Or i believe you can even get them from samsung's website.
And Congratulations on the new baby.
Sent from a CM9 powered Epic.
the link you posted has all the best instructions. Do not skip a step or circumvent any. Use the file links he has provided. And use Odin 1.85.
Take the battery out of your phone let it sit for at least 20 minutes, leave the battery out plug it into computer and attempt to get it into download mode.
Very important your not using the Samsung stock charging cable to do this. You need a good USB cable, one like the Blackberry phones come with, which is designed for heavy data transfer
Good luck.

The problem and the cause of your woes is a faulty cable. Get a heavy duty blackberry cable and try again. This time leave the battery out, using the cord as power put it into download mode with Odin already up on the computer and make sure to use the same port that it has been working in.

I actually tried a differnt cable because of the original link the first time, and that didn't work at all (used my wife's evo shift cable). But, I did find yet another micro usb cable in the house, and that one does seem to be working. Although, the odin flash does not seem to be, seems to be hanging (and the phone shows just blue across the entire screen), but that is progress =) Thanks for the tips everyone. I'll post my findings if I am successful in un-bricking. (or post where i get stuck next =P) Thanks again everyone.
When you get stuck again, Odin with the battery and sd card out.
Already took the SD card out. I can't go into download mode with just the cable though (already tried). Any recommendations? To get into download mode currently, I have to:
unplug everything
take out the battery
pop the battery back in
then, 1+power to download mode.

Sounds like either the cable still has issues or the USB port is not properly powered. If a desktop, use the USB ports in the rear right on the motherboard. I see you have had different results from different cables already, if you can just get ahold of a heavy duty Blackberry or Palm Pre cable.
How long should I wait before re-trying a new flash? It's been stuck on cache.rfs for the past 2 or 3 hours. I'll try the back usb port instead of front usb ports. I'll also try a palm cable, I think I have one lying around somewhere. Thanks for the tips.

Following the original link, what I had to do was:
I plugged into rear usb
still wouldn't go into download mode, so unplugged, popped in battery, went into download mode, plugged in
started odin 1.61 (as in the trouble shooting part of the original link)
Used EC05 rom (as in the trouble shooting part of the original link)
my phone is back from the dead! Thanks for the help everyone.
Congrats man!

[Q] Can I get root w/o USB?

So the short question is if there is any way for me to get root without a working usb port?
Last week I plugged in to charge my phone overnight with the phone off. In the morning, I was surprised to find that the screen was on and what should have been a full green battery was instead a scrambled image that kind of looked like a battery. I powered on the phone and it worked so I thought nothing of it but later on that night I needed to pull a file off my phone via usb and realized that the phone will no longer detect the usb host, ie. no mtp options whatsoever. It at least does still charge.
Since then I have tried cleaning the usb connector, pulling the battery/sim, setting the UART using *#7284#(PDA, mtp+adb), multiple computers, and multiple cables(including the Samsung one) and the phone still doesn't ever think its connected to a host. So today I decided to use my php warranty service which meant I had to restore stock recovery and rom. So I grabbed mobile odin and a stock UVLDJA image. Ran Triangle away once to clear the counter, and another time to verify it was at zero, and installed the full image via mobile Odin. When the phone booted back up, it successfully installed the rom only the flash counter is back at one and now I have lost root. If I had used my head I should have flashed just the recovery first but I wasn't thinking....
Any suggestions on how to get root back? I read these forums quite a bit and I am thinking that I am SOL but hoping maybe someone has a suggestion I haven't seen yet.

Checking your flash counter in TA trips your counter, that's why it's at 1. Use mobile Odin to flash root66 to get rooted again.

Oh, duh! Yes lol you do. There would be no other way. Have you tried a factory reset then try to connect your phone? You could also try to install Kies on your PC to make sure all drivers are correctly installed.
If you wouldn't have said you have tried other cables, I would have for sure thought defective cable. Some cables are also charge only.

Yeah, did the factory reset along with all of the other suggestions I could find. I typically try to avoid Kies and since I cannot even get the device to enumerate I'm pretty sure it's not driver related.
I think my only hope would be getting root or twrp intalled via stock recovery or adb over wifi.
Thanks, I appreciate the help.
download Odin3 v1.85
Put your phone in download mode (vol down=menu=power then after the screen comes up press vol up
plug the phone usb to the computer,
run odin
the first box on the top left should have a colored highlight (the ID:COM )
if that pops up, your phone is 99% functioning correctly, and only problem is in your computer.
When trying do do a regulad usb transfer to the computer:
I have noticed, sometimes I have to connect, wait a bit (like maybe 2 minutes)
then disconnect the cable for about 15 sec then connect again, and it pops up after a minute
you could also try this:
open explorer on the computer(double click on my computer) and see if there is a t999 in your left pane. Sometimes the autorun function in the
computer gets farkled and it does not open automatically and you have to do it manually,
Good luck & Aloha !
Go to galaxys3root.com and follow his t.mobile root tutorial WORD FOR WORD. USE THE USB THE PHONE CAME WITH AND KILL SAMSUNG KIES. also run Odin before you connect the phone to Pc, should be no problem bruh once it took me a couple of hours making love to my comp before I got a colored com box. And use a windows PC Mac suxx for this kind of.

I've basically given up trying to get the usb port working... I am convinced this is a hardware issue. Nothing shows up in the device manager when I plug in the phone whether USB debugging is on/off or I am in normal mode or download mode. The phone will never bring up the MTP options in the notification bar either. Again this is with multiple cables on 2 different comps where it used to work just fine. I think whatever bad charge experience I had last week damaged the USB host controller on the phone.
I think what looks promising now is using adb over wifi(http://forum.xda-developers.com/showthread.php?p=26844535) along with root via adb(http://galaxys3root.com/galaxy-s3-root/how-to-root-u-s-canadian-dual-core-galaxy-s3-on-mac-osx/). I can't do this at work but I'll follow up tonight on what will hopefully be success in case this could help someone else out.
Edit: Ugh, some quick googling shows that I need either root or working USB to make adb over wifi work.

I don't think so.... the micro usb port is mounted on the main board and short of replacing that entire board it would be a ton of time/effort for something that I don't exactly think is the problem.

This happened to me, and it was from using different devices in the same port (with same cable). I switched ports and it worked. Might not work for you, but worth a mention - it really stumped me and I tried everything including restoring the OS to an earlier point.

Now that S3's are getting older, more people will be losing their functional USB ports. I found holding the phone vertically with steady even pressure on the plug was the trick to getting a solid connection on my flaky port, at least enough to get stock back (to send it back). That was the longest 15 minutes of my life (OK, not, but it was in the top 10, mostly because it was simultaneously nerve-wracking and insanely boring).
I tried de-soldering a usb port on a Galaxy S. Yeah.... To say it mildly, the way Samsung sets them up is booby-trapped. You can't get the existing silver solder hot enough to melt without toasting the board somehow. The boards are also wafer-thin and dimensional on both sides. Despite generally having a knack for fine tuning and detail work (thanks to estrogen or something), I felt like an ogre in a doll house. I definitely would suggest having all the (exactly) right tools in place before tackling it. Even then it might not be the port itself, but something between the actual port and the other components.
One other thing to note, Mobile Odin is an amazing tool, but it's even ***more crucial*** than regular Odin to get your ducks in a row before you flash. Know exactly what you are flashing what your next steps are, and what your results are supposed to be. One thing in particular: if you flash a stock ROM, it includes stock recovery, and you will lose root. make sure you've run Triangle Away before you flash stock (which won't trigger your counter, but anything else will).
I plan to keep the Triangle Away and Mobile Odin apk's ready on ExtSD to install, and a copy of a stock image (ROM) as well, from now on, on all my phones. You never know when that port is going to give up the ghost.
Just thought I'd add a couple things here. More times than not, when someone thinks their usb port on the phone is bad, it's actually just the cable. Even if the cable works on something else, or works to charge the phone. They ruin much, much, more easily than anyone wants to believe! Especially when you plug/unplug it as often as with a phone.
As for Mobile Odin, I fully agree! It's one of my favorite apps by far! But if you're going to keep stock firmware handy, which I highly recommend, you may as well keep the root66 version. Flash back with that, then run triangle away, then in SuperSU, choose full unroot. Then all you need is a factory reset. Making TA the last step makes for far fewer user mistakes.

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!

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?

Turns on but won't boot

I have an I747 that was running CM13. It was fully updated, NJ2. Had TWRP 3 on it. It was running great and one day the battery died. It charged for a little and will turn on, but not go past the CM guy logo. I tried booting into recovery and same thing, I get the TWRP logo but doesn't go beyond that. It goes into recovery but it's not recognized by the pc when connected. It's almost like the internal card went bad, and that's why it turns on but won't boot. Any ideas? Any help is appreciated
Did you try a factory wipe? Reinstall the same or different ROM?
I can't get into the ROM or recovery to do a wipe. I have a back up I'd like to try to restore first, but I'd gladly try any ROM I could get to work
Can you get into download mode to reflash twrp?
I tried. I can get into download mode, but when I connect to the pc, Odin never shows as connected. Usually it turns blue and says like COM1 or something
Are you using the original Samsung cable? Tried using different USB cables and USB ports?
It's not the original Samsung cable, but I've tried a few different ones. Tried every USB port on the computer.
One of the cables I retired I know works for data transfer because I use it for a different Samsung phone
It's possible the USB port is damaged. I have found with my s4 that even if a cable can transfer data, it can't flash a ROM in Odin.
I thought about that too. I found cracked screen phone on ebay so I can try a new internal board. It was cheap so figured it was worth a shot. Thanks for all your input.
I'll keep you posted with whatever happens.
So I got a new/old phone on eBay. Cracked screen but it turned on. I got that, opened it up, pulled the board out and swapped it in with my good screen. All is working new. Got my cm 13 working again. Thanks for your input.

can i get some help???

ok, so here's what's going on:
Google nexus 2013 wont start up. It was previously Dead Dead, but its been charging, so it can start up now. However, i shuts down when i take it off the charger, but thats bc its not fully charged yet.
now for the real issue:
It seriously wont start up, it gets to the google logo, but it just shuts right back off after that. and sometimes, when i power it on, the google logo flashes on screen for less than a second, and then shut off immediately afterward, and i can't get to the bootloader when that happens.
when i AM able to get into the bootloader, i've tried everything. i wasn't going to factory reset, but when all failed, i tried it. But even THEN it didn't work. instead of bringing me to the next page, it just shut off again. can I get some help pls? (BTW it isn't charging with the cable it came with, its charging with a samsung j7 charger, but i made sure that its working)
If it turns on at all, then it isn't completely broken I believe. Have you tried the re-stock method shown in the forum? You just run the .bat file inside it and it'll flash you back to the latest stock firmware. It is supposed to fix any soft-brick issue.

How? i can't get it to connect to my pc via USB because USB debugging is off. I also need to get the official nexus 7 charger because it's not charging at all and i can't get it on.
Ah, you didn't mention usb debugging wasn't enabled... Hopefully someone will be along asap with a better solution

You don't need official charger. Any is suitable.
Any microusb in good working order should work. Check the charging port is free of lint and other dirt so the connection is good. Is the device showing that it is charging? Even off it should show that it is taking a charge. If not, and you are certain the charger is in good condition and seated properly then it may be a faulty or failed battery. I know mine is going, just won't hold a charge very long. If you can get into the bootloader, you can fastboot the factory packages regardless of adb debugging being enabled. You just can't flash non signed images unless you are bootloader unlocked. If you can boot into bootloader then fastboot back to stock would be my suggestion to start.
