[Q] Galaxy Tab hangs on Galaxy Tab Logo after firmware upgrade

Hello, I have upgraded my galaxy tab (pda jj3-phone jid - csc jj2) to roto jmi firmware with odin 1.7. all the process seems to be ok, no error message.
After rebooting, the device hangs on galaxy tab samsung logo. factory reset is no longer possible. Does anybody have a idea?
Many thanks in advance.

Ever heard of "if it ain't broke dont fix it"? So, there you go

sure... sure but now it is

Try using volume UP rocker + power button.
This should put the phone into recovery.. Then you select reset to factory defaults. That should do the trick.

thx kragebein, unfortunately my device won't to go in recovery mode

Are you sure you are doing it right? Hold down the up volume rocker and the power button at the same time until you hit the recovery screen? Optionally you could try to see if you get it in download mode, and reflash your phone.. i had severe problems with mine, but got it fixed today by using roto-jma rom..

Yes, I think I dit it right. Download mode can be activated with volume down & power, but not recovery mode with volume up & power. I have tried to load the firmware again without any error message, but no way.

Same here. Whatever I do (flash) I don't get past the Samsung Boot screen.

You need to flash a complete rom, like Roto JME FULL v.4 with the tab in download mode. He gives complete instructions.
Some releases are just upgrades, so start with a complete rom.

I have tried that and either it fails to upload the primary bootloader (boot.bin) or it stays the same after flashing: it doesn't go beyond the first Samsung Screen. No adb connection possible.
How can I flash a primary bootloader without protection? With JTAG only?

A forum member, Rotohammer used a Jtag box to fix the bootloader issue. He doesn't recieve PM's, but someone he collaborated with to solve the bootloader issue is a fellow named Chainfire. Perhaps you can contact him for the procedure.
But when you flashed the JME did you use the hidden .pit file with repartition selected?
If I was in your spot I would
1. turn off the tab (push power button for 10 sec)
2. then push power and volume down to go to download (yellow digger screen or phone and pc screen)
3. Connect to pc with odin3 already opened, wait until the yellow box shows the connection
4. Load the p1_hidden.pit and check repartition
5. Flash that, then power off, go into DL again, load and flash JME v4 full rom
6. Now flash a modem

hi guys im thinking that u guys may have flash a lock bootloader rom
or u actually already have a lock bootloader rom
try load a roto jme v4 full version see if it works~
1. download odin 1.7
2. download Addon-JME-Modem.zip / P1_add_hidden.pit / Roto-JME-Full-v4.zip from http://files.deodexed.com/ModADroid-Galaxy-Tablet/Rotohammer/JME/
3. and follow the instruction here http://forum.xda-developers.com/showthread.php?t=895827

I wish i said that.

The bootloader mentioned above is in a thread about the black screen and white line you are experiencing. It has the link to that jj4 file.

Thanks, but this didn't help. I think it may be a hardware issue (e.g. the kernel can't be loaded, panic or something). I will return my tab tomorrow.

WILL PAY $30 to anyone that fixes my Verizon Galaxy Tab!!!

I recently purchased an off contract Verizon Tab from a friend.
I had successfully rooted it using the superoneclick.exe file.
I since decided to flash Overcome_v1.2.1 with Odin using the exact steps as listed & even watched the video 2x.
"Click start and wait for PASS! to show highlighted green on Odin.
9. Your Galaxy Tab will Reboot, and get stuck on the Samsung Boot Screen. This is fine.
10. Turn your Galaxy Tab off by holding the power button for about 5 seconds.
11. Turn your Galaxy Tab on into RECOVERY mode (Press Volume UP and Power On at the same time).
12. The Galaxy Tab will now perform the EXT4 conversion.
13. Sit tight, depending on how much data you have, this can take quite a long time.
14. Once finished, click reboot system now (by pressing the power button)."
Now...I don't know what "quite a long time" is but after 30mins, there was still nothing but a blank sceen w the tell tale sign of a light, thin, margin type as seen on the video.
I then followed these steps:
"IF your Tab does not boot after flashing the kernel and hangs at the Samsung Galaxy Tab screen, you must follow the following procedure
1.Get a stock rom package (any of Rotohammer's firmwares will work)
2.Get P1_add_hidden.zip attached to this post and extract the P1_add_hidden.pit file
3.Using Odin 1.7, put stock rom (Roto-JME-Full-v4.tar for example) in PDA slot.
4.Put P1_add_hidden.pit in Pit slot
5.Check repartition box
6.Put Tab in download mode by holding Volume Down and Power, connect to the computer, and press start.
7.After this, the Tab will reboot normally. Shut it down and return to download mode.
8.Open Odin 1.7 and reconnect the Tab.
9.In the PDA slot, choose the Overcome Kernel v2.0 tar file for use with Odin. Press start
10.It will flash the kernel then reboot. Upon reboot, you should hear the sexy robot voices informing you of the status of the EXT4 conversion.
11.Once done, the Tab will boot normally. At this point you can load Overcome v1.2.2 rom (or any other Rom of your choosing)
12.NOTE - Overcome 1.2.2 includes v2.0 of the kernel, so no reflashing is required after install."
I never got past the part in step 10 to hear any responses. And instead of searching for one of Rotohammers FIRMWARES as suggested, I input a kernel from Voodoo!
Now I can STIL get into DL mode but whenever I try a normal reboot or recovery, it runs through -Wiping DATA- Formatting DATA---DATA: Wipe failed!
over and over until the Tab reboots and when the samsung splash screen somes up, there is a weird "flashing" of the screen in multiple colors.
PLEASE...for God's sake...with all the great inds on here, someone help me!
Please email me @ [email protected] or call/txt me on my GV # 401-213-9555 I will PayPal or Wire someone a "service charge" for their assistance!
Thank you & I hope i did not break any rules on here by asking.

You need to find a stock Verizon firmware and flash through Odin
I just did a brief search and found this: http://forum.xda-developers.com/showthread.php?t=855415
But I'd ultimately recommend flashing this: http://forum.xda-developers.com/showthread.php?t=941749
And you may need to flash this to get to a stage where you have a working recovery image: http://forum.xda-developers.com/showthread.php?t=941781

Thank you very much! I will attempt that. I seem to be stuck in DL mode though.
I was downloading in Odin and the Tab has been stuck at 95% for the past 30mins.
Should I power off or is it a sure fire way to brick it?

Assuming there are no bootloaders being flashed you can't really make it un-recoverable. What exactly were you flashing?

But if the advice from The Freak, he earned it

Any idea why it keeps getting hung up right about 99%?

hi
hi friend
i had simmilar problems in past.
Maybe you have problems with the usb ports of your machine.
If you have amd/sis/via for usb chipset at your computer try to do the procedure with another machine with intel chipset.
I hope this helps you

How to Re-stock P1000 to Gingebread 2.3 | Guide with Links

NOTE : this is not my own procedure but i just wanna share this with you guys since some tab users here are having problems restocking their tab to gingerbread, i have also added some notes and troubleshooting in case there will be an issue flashing the rom
link to the original post credits of course to the writer > how to restock p1000 to gingerbread 2.3
btw, this is a complete and full tutorial/step-by-step guide on how to restock gingerbread rom, so if you did not download all requirements, restocking wont be successful
my story and experience : hey guys, yesterday night, i softbricked my galaxy tab p1000 which was running cm9, it turned out like that when i went to recovery and wipe all data, cache, dalvik, even system, and boot. i tried reflashing the cm9.zip but as it was installing its update, my tab suddenly boot into battery icon, meaning it was already empty (maybe, dont have any idea), then, since it was already 12 midnight, there were no internet cafes open in our village, so i went out though somehow it might be dangerous for me, then, i found an internet cafe open. i rent a pc, first, i tried to go to download mode, so some drivers will be installed, but it kept showing "unkown device recognized" bla bla.. still.. i didnt lose hope. so i searched on google, and i found this site > http://suzhipackz.blogspot.com/2012/07/how-to-re-stock-samsung-galaxy-tab.html , when i finished downloading odin, i opened it to check whether it will read my device or not, first three attempts, it did not. so, i thought of downloading samsung kies so the drivers will be installed (safest way really to install samsung drivers), then i still looked for a smaller file (while waiting for kies to complete its download), then i found that there is a smaller zip file for you to install samsung drivers (see attachment below), i installed it, but still odin cant detect my device (try it, might be just on the pc i rented), so i just waited for kies to complete.. after a couple of minutes, successfully downloaded kies, and installed it. i tried connecting tab to pc with odin opened, i rebooted to download mode again and reconnect tab to pc, and voila! odin read my device! so, since pc has already detected my device, i just waited about 1 1/2 hours for the rom and the pit file and the db data file.... after almost 2 and half hours of crossing fingers, i have revived my tab and restocked it to gingebread 2.3!
HOW TO RESTOCK SAMSUNG GALAXY TAB p1000 to 2.3.3 GINGER BREAD STOCK ROM?

Samsung Tab P1000 stuck in nowhere!
First of all thanks the OP for the brilliant post on how to re-stock GB on P1000.
Earlier today I was fooling around with my P1000 to update it from CM11 to Omnirom 5.0.2, troubles started there. I was trying to install the TWRP recovery over CWM, and that is when all hell broke loose.
1. P1000 couldn't mount my internal SD. The tab was perfectly booting to a previous version of JB CM sapir, which I don't have any clue appeared where from. The storage showed the 2 GB internal memory, but the 12GB internal SD was missing out.
And the CWM errors were E:/can't mound internal SD
2. Now, after wiping data, dalvik, battery stats, formatting and all that, the tab doesn't even boot into the OS. The moment the power button is on, CWM initiates a count down saying, trying to mount SD, but unable to do so. After 20 seconds, the tab starts this whole process again, and thus a loop.
3. I tried to re-stock to GB; but my tab isn't being detected by Odin in download mode. Odin detects the tab when it is turned on and when the tab is on countdown-restart-countdown loop; but not in download mode.
I am a total noob, and I don't want to throw my tab away as I am a student and can't afford to get a new one Someone please help me to fix the issue. Thanks in advance!

Boot Loop after installing a custom ROM

Hello..!!
I need some help here. I tried to flash a custom ROM (X-Note (build 6.0) for Galaxy S5 GM900F) and then flash a new bootloader, the problem is that my device will never pass the booting process. I was stuck with the logo and black screen. I have searched and tried tons of tutorials and fixes but have not solved it.
I even tried to wipe Dalvik cache, wipe data, format system. I even put out the battery and leave it for sometimes, then on but the problem is still there.
This link to bootloader that I downloaded and flashed using Odin (after successfully installing custom ROM) and also the instructions that I followed to install the custom ROM.
https://www.androidfilehost.com/?fid=23622183712475277
When I try to re-install stock Samsung via Odin, it shows a Fail message. I don't know where to go from here and I'm really worry that my phone will never come to work.
Please help me to solve it.

fffft said:
I'm too busy today to describe this in detail.. but here are a few comments that may help you.
First, it is fixable. Usually it's enough to boot to recovery mode (phone off, then press and hold home + volume up + power buttons). Then from the recovery mode menu, choose wipe system cache. Then reboot. If you still have an issue then try a system data format from the Settings menu (this will erase user files!).
And as a last resort, restore a backup (if you have one) or a full, stock firmware image with Odin or Heimdall. Odin is infamous for being a bit picky, so don't panic if you get a failed message. That happens to all of us. Look for a detailed Odin tutorial or how to flash back to stock firmware thread that has Odin tips e.g. use a different USB cable + USB port. Temporarily turn off anti virus on your PC.. If the Odin write fails, do not close the Odin window. Just pull the battery and USB cable from your phone again.. put the battery back.. go back to download mode (home + volume down + power), plug the USB cable back, then press the start button in Odin again. It's important that the Odin window was open the whole time.
It may take a few tries (Odin can be frustrating) but you'll succeed.

flash stock firmware.
go to sammobile.com
Search for grand 2 firmware
then download it.
The firmware must base on your country.
after that flash using odin.
after complete. Remove battery then insert it again.
go to recovery
wipe everything
then reboot system
wait about 10 minutes
congrats your phone is normal again

Solution to your problem:
You will need to download the NK1 version of kitkat 4.4.2 stock firmware.
1) install samsung kies or samsung usb drivers so that your PC will detect your phone.
2) Switchoff your phone first and put it in download mode by pressing volume down and home button and power button at the same time.
3) connect your phone to your PC through the usb cable and start odin. (The com port turns blue in odin which means phone is detected).
4) In odin, check the "Nand erase all" in the checkbox and then click on "AP" buttion and select the "G7102DDUBNK1_G7102ODDBNK1_G7102DDUBNK1_HOME.tar" file.
5) Click the start button and wait for 5 mins till the OS is installed.
6) After installation, on your phone it might show 'memory damaged' and 'erase memory'. Don't worry, nothing is damaged or serious, just click to reset and everything will be fine.
7) Done!
I have provided the NK1 version link to you from my google drive account:
https://drive.google.com/folderview...03NF9WUzJLTHVSVnkzWWN5aFVQSzVOS28&usp=sharing
(Please hit thanks if I helped you)

Thanks guys
Problem solved and it is working now :fingers-crossed:

I have this same problem and I downloaded the above file and followed the instructions accordingly, after flashing it is still stuck at REBOOTING TO RECOVERY for about one hour now.I guessing it might be related to hardware.

Which firmware were you on before the first boot loop? Flash that firmware, and don't forget to pull the battery afterwards.
(Don't hit thanks, hit the phone on a pillow/bed of you think its hardware related).

Solution to your problem:
You will need to download the NK1 version of kitkat 4.4.2 stock firmware.
1) install samsung kies or samsung usb drivers so that your PC will detect your phone.
2) Switchoff your phone first and put it in download mode by pressing volume down and home button and power button at the same time.
3) connect your phone to your PC through the usb cable and start odin. (The com port turns blue in odin which means phone is detected).
4) In odin, check the "Nand erase all" in the checkbox and then click on "AP" buttion and select the "G7102DDUBNK1_G7102ODDBNK1_G7102DDUBNK1_HOME.tar" file.
5) Click the start button and wait for 5 mins till the OS is installed.
6) After installation, on your phone it might show 'memory damaged' and 'erase memory'. Don't worry, nothing is damaged or serious, just click to reset and everything will be fine.
7) Done!
I have provided the NK1 version link to you from my google drive account:
