[Q] Help needed in strange thing at GT-P7300 - Galaxy Tab 8.9 General

Hello for Everyone!
I've a SAM Galaxy TAB 8.9 (GT-P7300) branded for T-Mobile (TMH). There are few of strange things about it.
The first: can not communicate with my PC and with my laptop. On PC runs WIN7 x86, on laptop I use Ubuntu 10.4 (Studio). I had installed the USB drivers for WIN, and the only thing is happened after plugging the USB-cable WIN wrote: "Can't identifying the plugged in Android device". The Ubuntu doesn't recognize my tablet
The second: I can not reach the Bootloader mode, download mode. When I push the VOL down at same time with the POWER ON nothing happens.:crying:
The third: after some minutes of sleeping mode of the device (for example: charging, not using) it POWER OFF. Or...something like this...blank black display and nothing happens if I push any of the buttons. Pushing about 20 secs of POWER ON button resulting a reboot.
The device is in stock 3.2 .
Any ideas what can I do for rooting process nad for custom ROM?

On your second point, to reach bootloader, turn on tab, wait until the moment the samsung logo pops up, then press volume down (the one closer to power button).
To root, add custom recovery and ROM, read the stickies in the android development forum. These may help your other problems. There are several reasons why your computers fail to recognize your tab. I would try different usb ports and cords if you can. I would install kies on the windows pc and see if that recognizes the tab. If none of that works, it may be a hardware problem.

Thanx for your quick reply. There are few cganges about the problems. Here they are:
The second problem about the bootloader and download mode is off. I picked parts of the device and there was a liitle problem with the VOL buttons...repaired and everything is fine with it.
The first problem about the communication is half-solved. On SAMSUNG laptop without (!!!) any drivers works fine the device. Flashed with a "stock" 4.0.4 (Checz) no boot, just splashed on the SAMSUNG logo. After ODIN-flashed one-file other ROM it was very nice...everything goes.
But the third problem is here after the good-flashing, too. In sleep mode or long not-usage periods it is something like POWER OFF.... During the picking to parts period some of the pieces (battery, flexes) were supervised...everything is normal. I think the device's main panel is wrong, but I don't know how I could look at it and fix it.

Phone-PC brick with no working 3 button - options?

Hi all,
I was flashing between Jf6 and JH7 today, wanted to see if flashing JH7 via different methods would give me a 3 button fix. (If it did fix it then flashing via Kies mini didn't do the job)
Ironically it backfired when Odin froze and I flipped out the battery
(Hey, I've been at the dl screen before when it was doing nothing and it survived!)
I plug the USB in, I get the exclamation screen
Do it with volume keys pressed, still get it
Hold down the volume + power and the screen goes blinking between exclamation and blank. I've tried releasing power keys at each point in those screens
I even took a video incase I'm not doing it right. Odin is running in the background. No USB plug-in 'pings' from Windows, as you can hear.
Anything I can do?
btw my bat build date is 8/13.. that bad week
I'm in Australia (bought phone off ebay) so sending it back to the States will be a bit of trouble.. I'm hoping I can work something out with the ebay seller otherwise I'll buy another cappy and hope someone finds the jtag points I guess.
same here. no button combo method that previous worked is working now. :/
OP, did you see this thread: http://forum.xda-developers.com/showthread.php?t=775911
not working for me, but maybe it'll help you ... ?

You may also want to try removing and then reinstalling the Samsung USB drivers on your PC.
I've verified there is simply no USB device being registered no matter what OS, the phone is just sucking power.
@The_Bishop: Did see that, exactly the same as yours, plug usb in, get that screen
Anyone want to be awesome and send my Capppy back to Samsung on my behalf?
best method that never dies when i was in your situation......
unplug usb, turn phone off, then put battery in, turn odin on, now hold volume buttons ONLY then insert usb in phone, you will see download mode with odin identifying the port;
hope it worked ?!?!?!?
Believe me I have tried everything. There is simply was and still is no way to enter recovery or download mode on this phone. Its hardware locked!
a little off topic, but how do i find my phones "bat build date" ?
I had the exact same problem. If you do a battery pull.. hold down both volume buttons and plug the usb cable into the phone while it's hooked to PC then it bumps you into Download mode. I did the exact same thing you did and am running froyo at the moment.
Oh.. no power button.. just both volume buttons.

Is on the underside of the battery, one facing into the slot.
i.e 2010.08.13

Done that. Exactly what happens in video. Both volume buttons down, plug in usb.. no response, just brick screen.
I had the same problem.. the phone didn't register USB.. have you rebooted the computer? I believe i did that at one point.

I did try once or twice. From another thread it was also said to disable driver verification on windows startup for x64 machines. which I also did.
Basically I want to hear from someone who:
a) has a captivate that could never enter dl/rescue via buttons, only adb
b) captivate didn't trigger a plug in 'ping' from Windows until they ??
FYI this is a Macbook Pro, and I booted into Win7 x64 Pro for flashing.
Hi I have the same problem..
What I did was this rooted with one click.. loaded Cognition 2.1.6 all was good..I saw the froyo so I thought lets try it. so opened up ODIN put it in recovery mode. with ADB could never get it in the button way.. it started to load and it froze. I didn't disable voodoo and IS THAT WHY I AM STUCK? I have tried every combo changed drivers computer will not see the phone.. is it a AT&T Phone
IS there anyway to fix it?? or can someone make a program to fix this? I would make a big donation if they did!!!
Thanks Forum!!
Yeah I had it in adb mode to enter download mode, maybe that is why it won't start back up.
I've now given the phone to a local mobile repair business, if riffbox or someone comes out with a Captivate rescue soon its probably as a end result of me
I sent mine back to Samsung as well. BTW, I have a battery from 2010.08.12 so I might be in the same boat. Wish I'd have used one of my OEMs to see if that made any difference, but I did not. :/
I have the same issue.
Rooted my phone through adb, which was fine. Couldn't get into recovery/download modes with hardware before then.
Now my phone is bricked, and not detected or even charging via USB.
wtf
If the repair shop cant fix it try this:
1.) Remove Battery, SIM Card and External SD
OR
2.) Press and HOLD VOL UP AND DOWN with USB inserted and THEN slap in the battery.
This worked for me, for some reason inserting the battery last did the trick.
Let me know if anyone finds a solution to this I have tried it all and my computer will not detect my phone. Has Samsung blocked this in there firmware?
Did you try what I posted above?
yep nothing if I could get it to detect in command prompt I could force it but it won't... the button thing didn't even work when the phone worked!
So ....

USB connectivity and Download Mode

Hi,
So I have 2 Captivates here with me, one is running on AOKP Milestone 6, and is recognized just fine by the PC, so we can rule out drivers issues
On the other hand the other captivate had eclair, so I got into download mode, and used a one click Odin package to KK4, after that I can't get in anyway to Download mode, I nevertheless can go into stock recovery. I should note too, that I have a jig that is working with captivate1 but not with captivate2, like I said, it is not going into download mode, screen stays black.
Whenever I try to get it connected to the PC, a pop up on the PC says (roughly translated): "that one of the USB devices linked to the computer ididn't worked correctly and Windows couldn't recognize it. click on this message to get more info on how to solve this problem".
After I click on it, a windows with the title " USB device not recognized" is shown and listed is what I know is supposed to be my captivate but instead it says "unknown device".
If I insert the battery the device would turn on, no need to press the power on button, but if I shut down the device, I can't turn it on with with the power on switch, I have to reinsert the battery, in other words it's like the power on button is stuck, I don't know how to verify this, and I don´t know if this is what is causing me the problems, though I dont think so. Power on behaves just fine inside recovery or with the device turned on.
I can charge the device with the PC or with wall charger just fine.
Thanks
Probably the power button as you suspect... They have problems with the power button, so I have heard.
But what about the usb not being recognized, and I should also add, that it intermitently gets recogonized and when it does, it gives the message I typed on the OP. Could the power button affect to this extent?
Is there anything that can be flashed from 3e recovery (from KK4 update)??
Nope. Stock recovery is very constrictive.

Galaxy Tab 8.9 3G Hard bricked?

I've tried to put a new ROM using Clockwork Recovery 6.0.1.2, during process it stuck for 4 hours and was turned off by power button.
After that tab don't react on power button, on pwr+vol up, pwr+vol down, pwr+ both vol buttons, nothing.
It even doesn't show battery icon when charging - screen is always black.
Any advices?
Thanks in advance.
I think the method described here will do the trick: http://forum.xda-developers.com/showthread.php?t=1478361
kallt_kaffe is having the same problem and he describes the procedure as: "basically tape down the power button to force a reboot cycle."

1. Put on your computer headphones and turn the volume up.
2. Plug your tablet into your computer via USB.
3. Hold the power button & Vol - keys together (Volume - is the side that is closest to the power button)
4. Listen for the "USB device connected" or "USB device disconnected" sound on your PC
5. If you can hear that, something has gone bad within the bootloader and the display does not initialize properly. Edit: The ICS installation does indeed attempt to patch the bootloader
6. If there is no sound, then the tablet is stuck in limbo, so go ahead and do the battery drain procedure as described in the above post.
7. If, however, your computer detects a device connecting and makes the sound, you can most likely still enter Download mode. You will have to do it blindfolded though:
-open ODIN 1.85 and see if it shows a connected device. If your PC made a connected sound, then there will most likely be a yellow COM port in ODIN.
- Hold [Power] & [Volume Down] together for 15 seconds or longer whilst monitoring your Device Manager windows to see if you can get the tablet out of APX mode and have it appear as another type of Device. Then press Volume+ several times with 1.5 sec. intervals. With luck, this should get you into Download mode, and ODIN will shine yellow for you.
- While doing all of the above keep your headphones on and listen for connected or disconnected sounds from your PC.
- Make sure you have this firmware for the P7300 which contains a bootloader, which is essential: http://www.hotfile.com/dl/162686792/c693269/P7300ZSKK2_P7300ZZHKK2_TGY.zip.html
- Flash with "Bootloader update" checked in ODIN and see if device is resuscitated. If the tablet boots, it will be in Hong-Kongish, but just select a language you recognize from the dropdown, it has them all.
- It may be a good idea to also throw in a .pit file and check Repartiton
N.B. The firmware link that I have provided is for the Tab 8.9 3G P7300 only! Do not flash it on another version of the 8.9!
You will need to search for a firmware that contains a bootloader.bin.md5 file for your tablet model.
Again, all of this will only be possible if the device registers with your PC on connecting the USB cable.

Ok, I've disassembled the device, and removed a battery connector for a time.
Didn't help though.
When I'm connecting tab to PC and holding pwr+vol_down, I hear that connect-disconnect sound and there is a device called
NVIDIA USB Boot-recovery driver for Mobile devices blinking in Device Manager with those sounds.
Odin shows no yellow com, all are empty, so download mode is not available.
you are stuck in APX mode , First go to this link and follow the instructions : http://forum.xda-developers.com/showthread.php?t=1130574]
if you get this in nvflash :
Nvflash started
rcm version 0X4
Command send failed (usb write failed)
this means your device is locked and the battery draining is that last thing that might work for you .
i still didn't try it, but i only disconnected the battery and connect it again but my device still dead for a month now .

I'm getting exactly what you posted:

Command send failed (usb write failed)
and right after that tab disconnects from pc and disappear from devices list.
is it possible, that some Samsung Service Center will help me? I think that what I did voids the warranty, but anyway, I'm in Ukraine and getting official support here is almost mission impossible.

unfortunately the sbk (secure boot key) for locked Samsung devices is unknown and i was hoping that someone will be able to provide it since it's now increasing problem for 8.9 and 10.1 tabs especially after ics update . actually this is well known mode(apx) with all Nvidia Tegra devices such as acer a100 tablet and asus transformer ee pad but developers there were able to find the sbk for these devices .
if you are covered by warranty and the battery drain method didn't solve the problem you should go to Samsung and good luck . i am not covered by warranty and the only solution i found after connecting Samsung here in Egypt is replacing the mainboard costing almost as a new device (even Samsung couldn't fix it) .

Sounds like they want to get your cash.
If things went to sh*t software-wise, they can be fixed the same way.
They could just UART into the board and restore the bootloader. I don't have to expertise to do it, but they should have it.

1-7 okay. And device is "NVIDIA USB Boot-recovery driver for Mobile devices", not APX (because i installed special driver).
But nothing happend when i try to enter Download mode.
USB Disconnect > Connect > Pressing power and vol button for ~7 seconds (why 15+?.. So 15 i tried too) > Sound > Pressing V+ 10 times... Nothing glows in Odin.

I had a broken bootloader and my display was dead the same way all of youse with bricked tabs describe.
It appears that in your case the bootloader is so badly messed up, that a fail-safe kicks in and sends the tab into APX mode directly.
Consider disassembling your device to disconnect the battery, press Power a few times with ti disconnected and keep it disconnected for a minute or so to force discharge of all capacitors, then reconnecting and attempting a reboot.
Disassembly is really easy - get a plastic knife and stick it under the display near the charging port and work your way around the whole unit. The entire display comes out of the back cover. Flip the display around and there you will notice where the battery connects to the main board, unplug the connector.
Have you tried?
And wut i must do after that?
---------- Post added at 11:46 AM ---------- Previous post was at 11:11 AM ----------
Disassemble, disconnect battery, press power, short + and - (on device, not on battery lol)... After that connect battery and connect via usb ... the same. cant enter download menu.(
Will try this > http://forum.xda-developers.com/showthread.php?t=1478361

Hi, may I know what new ROM did you flash? And your previous ROM before flashing. So that we can all avoid that ROM until somebody can fix this mess cause by brickbug. Thanks.
Nah. Samsung service sucks.
They said that motherboard should be replaced.
I don't understand how software problem couldn't be fixed w/o hardware replacement.
Screw that, I'll go get Nexus 7.

Actually it turns out to be the problem with CWM 6.0.1.2. You should use 6.0.0.8 or less.

My tab has a blank screen and went through the steps you mentioned. ODIN has a yellow com port and when I try to flash the firmware+bootloader ODIN stops in "SetupConnection".. I tried to change port, cable, odon version to no avail. Any ideas? Thanks!

[Q] Bricked SCH-I800 Galaxy Tab, how to flash?

Hello,
I have just received a Galaxy Tab SCH-I800 (Verizon version) from a kind person in the USA and it's not working. (I knew that beforehand though)
I think it might be bricked, but I'm not sure.
Here is what happens:
· When I try to power it on, nothing happens (might be the probably dead battery though)
· When I plug it into my PC, nothing happens, then after 10-15 minutes, an icon shows up showing a phone and a computer with a yellow triangle with an exclemation mark inside between them, the tablet stays in this state and my PC (running Xubuntu Linux) recognizes the tablet as an USB ACM device, but I can't connect via adb
· When I plug it into the wall charger, said icon shows up, stays for ~10 seconds, the tab restarts (no icon for a few seconds) and this cycle continues infinitely
EDIT: I just noticed that the tab doesn't stay on forever when connected to my PC, it just turned off again after about 10-15 minutes.
From what I've read in the forums, it might be a soft brick.
Is there any way to fix this and get the tab running again?

So you say I have to let it charge and then it'll work? (I just plugged it from PC to wall charger and it didn't turn off right away, it stayed on. I guess that's a good sign?)
Also, how can I interact with the tab if it's only being recognized as an ACM device?
ACM devices are byte-based serial devices.
Does your linux machine mount it to /dev/ttyACM0?
If so, this may be a emulated serial debugging terminal from some kind of bootloader.
Try to connect to it (on several baudratings) via PuTTY or minicom.
Greetings,

Nope, that didn't work.
I tried many possible combinations of flashing PITs, Kernels, Recovery images and so forth, but the best I've achieved until now is that the tab shows the Galaxy Tab logo, then goes to a black screen, plays the bootup melody and then freezes.
I can also enter both the stock recovery and ClockworkMod Recovery, but in both cases, the screen gets all gerbled up before entering recovery and the screen remains black during recovery, meaning that I have to use it blindly.
I can't connect via ADB either. Please, can't someone help me?

Galaxy Tab 10.1wifi is going to be thrown out the window !

Ok so this will be my second post, no one replied to my first.
Will try to explain what the problem is. in as much detail as I can.
Please help me out guys !
So, tab was in debug mode, messed up using odin, trying to root, not sure what went wrong there and gave up.
Rest of the day tab worked fine.
During the night it was not turned off but left on charger, icon showing.
I listen to audio book while falling asleep
When I woke up, pressed on and nothing, black screen
Panic and frustration followed.
New charge cable, black screen
Searched internet, did the button combo's , took back off, disconnected battery, drained battery, still black screen.
Disconnected all cables inside, reconnected, black screen
Conncted to win7 pc, by holding down power and vol down, pc sees unknown device in APX mode.
Installed various drivers, all I could find that might work, installed and seen in device manager.
Followed nvflash guides, get an error usb write failed.
List devices command, nothing appears.
Installed Samsung Kies. cant connect , using different drivers also.
Odin cant see the device either. Pdanet installed, same outcome.
Also the sdk route, always no device found
I havent got new battery yet, cant afford one at the moment.
With everything I tried it always comes down to device not being seen even though it does appear in device manager.
Installed usbdevieuw software , check the properties, it does say 0mA , which is different to when I check my usb keyboard or mouse, they do have power 90mA etc. which is weird.
I have read and tried just about everything concerning my specific device. I am stuck.
No idea what to try next.
I understood that apx = download mode., which would be fine if I could see something on the tab screen. I know that normally when into download mode you have to use vol up to cross over to the right icon.
So, power + vol down... wait till its in device manager on pc, then vol up. Tried this, seeing as the screen is black I just waited a bit and then vol up, guess work actually.
Anyway, if someone has any ideas etc please let me know.
Thank You All
Try This

Thank you !! for responding. I did as you suggested, Its cool software.
that being said, no matter what option I choose I get The system cannot find the path specified. To me that means that the tablet cannot be entered even though it does show up in device manager samsung android phone> android adb interface.
I mailed samsung help desk and got a reply saying, take it to your nearest samsung repair store. .. THEY can fix it......as I expected they would say.
Im still wondering if the battery is causing the problems. As screen is black, when on charger stays black.
However if the tab is seen on my pc, does this mean tab has power?????
I have no idea how to test the battery without replacing it.
Im guessing tab is fully bricked and if so would that explain the no battery charging icon??? and lack of any other screens lol :laugh:
Anyway, I have learnt so much from reading this forum. I admire the great work and assistence provided.
Guess my tab problem is either too easy to provide a fix for or hardly no one has a clue how to fix my tab :silly:
Please respond and help me out!!!
