[Galaxy Tab Q&A, Help & Troubleshooting] MAJE5T1C:
im in the same bout as you mate did just the same thing was working fine on voodoo lagfix wanted stock back flashed now stuck at samsung logo

All i can say is check to see if you still have the recovery mode in your tab by holding up volume and power button the let go of power and keep holdig up volume when you see it boot to samsung logo

If you have lost your recovery mode your stuffed your bootloader is locked and theres nothing you can do to bring it back its time for samsung service to sort it out
[Galaxy Tab Q&A, Help & Troubleshooting] aning_019:
Can you still put your tab in Download mode?

If so, you can try to reflash DXK.

1. Use the p1.pit file for PIT and DXK for PDA.

2. Select re-partition on.

3. Maybe this time after the tab reboot and the odin pass you'll be stuck at the recovery mode, error will be E : Cannot mount dbdata. . .

4. To be out of this you could select format/restore, navigate using volume up/down then press home button to select that option.

5. Then go back to menu and select reboot.

-- inform me if this works.

Edited my first post :

Yeah, you're totally screwed with a protected bootloader!

I just downloaded the P1000DXKM2 @Samfirmware and discovered that it contains sbl.bin, boot.bin, and the zImage file size is 7860 Kb.

See this forum http://xdaforums.com/showthread.php?t=888071

Followed your instructions but it's stuck on the Samsung logo.
[Galaxy Tab Q&A, Help & Troubleshooting] aning_019:
Sorry, did u follow my first post?

After i download DXKM2 in samfirmware i discovered that it contains new bootloader, containing zImage more than 4,000-5,000Kb.

-- in short flashing that with repartition will have the same result as your first attemp.

This time will you try to flash Roto's JMEv4_full safe rom. Same steps as my first post.
[Galaxy Tab Q&A, Help & Troubleshooting] prinzhernan:
I flash roto's when I want to restore my tab and put a custom rom. What I need to find out is how to put a DX rom into it so I can send it to a service center.
[Galaxy Tab Q&A, Help & Troubleshooting] noxxious:
i encountered something similar to this before when i was testing out the 2.2.1 HK rom. i also made the mistake of flashing protected bootloaders onto my tab, though i reverted it back to unprotected bootloaders using Chainfire's and RotoHammer's bootloader patcher http://xdaforums.com/showthread.php?t=888071.

as for my stock firmware then, mine was P1000DXJK2. what i did was dl the P1000DXJK2 from samfirmware. I then removed boot.bin and sbl.bin from the tar package (i patched the unprotected bootloaders onto my tab), and added a dbdata.rfs into the tar package. i then flashed using odin (flashed with no pit). and i got it back up and running.

my P1000DXJK2.tar file contains the following:

cache.rfs

dbdata.rfs

factoryfs.rfs

hidden.rfs

modem.rfs

param.lfs

zImage
[Galaxy Tab Q&A, Help & Troubleshooting] prinzhernan:
So Samsung won't notice that I have unlocked bootloaders when I send the tab to them? Where do I get a dbdata from?
[Galaxy Tab Q&A, Help & Troubleshooting] noxxious:
nope. they won't notice. but if you want it to have signed bootloaders, you could just add the dbdata.rfs to the TAR package.

i have attached the dbdata.rfs that i used. got it form GT-P1000-CSC-MULTI-OXXJK2.
[Galaxy Tab Q&A, Help & Troubleshooting] prinzhernan:
Thanks for this. So you mean the reason why the rom won't boot after flashing because it lacks this file? What does it do exactly?
[Galaxy Tab Q&A, Help & Troubleshooting] noxxious:
i actually don't know. :)

but from my experience this solved my flashing problem when i tried to roll back to stock firmware.

when using heimdall it is listed with cache.rfs under CSC
[Galaxy Tab Q&A, Help & Troubleshooting] vince_junior:
May i ask why you are sending your tab to samsung for repair?
[Galaxy Tab Q&A, Help & Troubleshooting] prinzhernan:
I placed dbdata.rfs into the exact same rom that you used and it fails at dbdata.rfs flash. Odd.
[Galaxy Tab Q&A, Help & Troubleshooting] noxxious:
That's weird. You extracted the dbdata.rfs from my zip right?
[Galaxy Tab Q&A, Help & Troubleshooting] prinzhernan:
Yes, I did. Then I stuffed it into the .tar.

If it's not too much of a bother maybe you could upload the working .tar that you used?
[Galaxy Tab Q&A, Help & Troubleshooting] noxxious:
ok. im currently uploading the tar i used. i removed boot.bin and sbl.bin from the tar and dbdata.rfs added.
[Galaxy Tab Q&A, Help & Troubleshooting] prinzhernan:
Thanks a lot dude! :)
[Galaxy Tab Q&A, Help & Troubleshooting] noxxious:

P1000DXJK2

Flash with no .pit

btw, what's the prob with your tab that you are gonna return it for warranty? :)

Thanks! Will try it now.

Thanks for the reply

I did a little research and it says SER is the sales code for o2 UK. I am on a multi-csc and it does not have the option for CPW when I do the *272 code :( is there a reliable place to get hold of CSC's? Samfirmware doesn't have them. Or am I buggered lol

overcome hermes to dxjk2 froyo

anybody could help me on this? i would like to go back to stock gingerbread firmware.
[Galaxy Tab Q&A, Help & Troubleshooting] prinzhernan:
God don't people read? The steps are in the first post.
[Galaxy Tab Q&A, Help & Troubleshooting] Lhon0901:
What prinzehernan says is actually true, the steps are included here and posted a lot of times already, courtesy of noxxious... Please check the first post, as the OP has already pasted the steps noxxious wrote... Also, just to make sure, make the last step mandatory as well, root and check if your bootloaders are signed, then unsign if signed... That will allow you to rollback the firmware to any version then flash to GB...

By the way, the steps mentioned are applicable to all flashes, so if you know how to flah one firmware, then that's the step you will do to flash another...

Lastly, for rolling back, I suugest to use odin as it flashes more completely than heimdall, if you can find the complete flasher, like the one I and noxxious posted for the DXKM3...

***Added: Okay, here is the link... Be sure to add the last step provided as well...

@prinzehernan: Please modify the link on the first post, shows a 404 not found error...
[Galaxy Tab Q&A, Help & Troubleshooting] prinzhernan:
Fixed the first post to reflect changes. :)
[Galaxy Tab Q&A, Help & Troubleshooting] jaen77:
About the signed bootloaders, if from dxjpc with signed bootloaders, to roll back to dxkm3, do we need to unsigned bootloaders of dxjpc before roll back? since both dxjpc and dxkm3 are official firmware.
[Galaxy Tab Q&A, Help & Troubleshooting] bongski55:
A big NO- don't ever use the patch on gingerbread as it will make it unbootable! The DXJPC bootloaders are signed but UNSECURED so no problem in flashing any ROM.
[Galaxy Tab Q&A, Help & Troubleshooting] jaen77:
Confuse now. A lot of instructions state to patch bootloaders before any rom flashing:confused:
[Galaxy Tab Q&A, Help & Troubleshooting] bongski55:
What's confusing?---I said don't patch GINGERBREAD-VERY CLEAR ENGLISH....

If you don't believe me then read this or use the search above for "bootloaders"......
[Galaxy Tab Q&A, Help & Troubleshooting] jaen77:
Thanks, need to read more. :)
[Galaxy Tab Q&A, Help & Troubleshooting] bongski55:
Noxxious and Prinzerman,

There is a new gb DXJPD have you upgraded and rooted?
[Galaxy Tab Q&A, Help & Troubleshooting] Lhon0901:
Okay, let me make this a little more clear...

1)If downgrading from GB to Froyo, do not unsign.

2)If downgrading from froyo to froyo, sign...

Now, When I roll back my firmware from GB to froyo, I usually flash at least 2 times... Why? Because usually, when I rollback from GB to froyo, PDA and CSC are blank when you do *#1234# so I flash again with another firmware, so I unsign going from one froyo to another froyo...

The steps I took:

1)From GB, flash to DXKM3, then I do *#1234# after flashing.

2)If PDA and CSC are there, nothing else to be done, if blank then unsign.

3)Flash P1000DXJK2, no need to unsign this time, this ROM is unsigned.

4)Flash DXKM3 back.

Note I flashed first with DXKM3, w/c has signed bootloaders... DO NOT FLASH FROM GB TO FROYO FIRMWARE WITH UNSIGNED BOOTLOADERS, OR YOU WILL GET THE PHONE-|-PC ICON ON RECOVERY!!!

Last step I did is to bring me back to stock firmware that came with my phone, you can flash other firmware or disregard if you are happy with DXJK2...

Hope this clarifies things...

[Galaxy Tab Q&A, Help & Troubleshooting] bongski55:
Me too,I like the stock. Yet if I figure out a way to disable/remove OC/UV from overcome then I might go for it. There is also CF-root which I also like to study how to modify the zImage file. Do you know how to do that?

Unfortunately I don't have a Linux pc to try and do some decoding.....
[Galaxy Tab Q&A, Help & Troubleshooting] Lhon0901:
Unfortunately, no... Last time I did some cooking was with the Motorola E6, and eventhough our OS is also a modified linux, I'm thinking cooking would be different with our Tab... There were tools before that can be used to compile, but it's been a while since I did it... Maybe we could get some help from the cookers here...

[Galaxy Tab Q&A, Help & Troubleshooting] dimedropper:
Noob here and need some help.

I am currently on Italy GB XXJPZ. Been having problem with the games and video recently. I want to go back to stock Froyo and then update to GB via Kies (I believe there is an upgrade to GB via Kies if you are in the Philippines). I get the steps from the previous posts, but I still havr to make sure I am in download modewhen I do this right? That's what I completely forgot how to do.

Before I can use Odin, I have to see the Android digging right? How do I do that? I guess more of fill in the blanks (with the download mode) in the previous step by step posts.

Also, I need to use DXJK2 right? This will get be back to Froyo then I just upgrade to GB via Kies.
[Galaxy Tab Q&A, Help & Troubleshooting] bongski55:
Seems you are new to this flashing step as even going into download mode you don't know....I advice you to get a friend who knows how to do this so it for you as flashing wrongly can turn your tab into an expensive paper weight. Take your tab to gilmore. I am sure somebody there can help you for a small fee....
[Galaxy Tab Q&A, Help & Troubleshooting] dimedropper:
^Yup. Definitely new to Android but I was the who flashed my tab from Froyo to GB using Italy's ROM and some step by step instructions from another thread here. I'm just not sure when to do the "download mode" (and how to do ot again...power + volume up or home + volme up) within the steps provided here.
[Galaxy Tab Q&A, Help & Troubleshooting] Lhon0901:
You go to download mode right before flashing, before plugging your TAB to the PC so that odin/heimdall will recognize your phone...

As for the key combination... I'll leave that to you to find out... I believe in being ready for any problems when flashing, as we are not always around when something goes wrong with the phone... If you are not even ready to go into download mode, then how can you fix the phone when you get the PC-|-Phone error on download? Better to read the stickies/thread here again so that you are prepared for the worst when it comes... Believe me, I got the PC-|-Phone error on boot... What would you do if it happens to you while flashing?

I'm not trying to be mean, it's just better be safe and prepared than sorry...

I guess you may have already found out the answer to your question about flashing and download mode, visit the thread again as the steps are usually the same, you just use different firmware for each flash...

Before I flashed the GB ROM on this thread and rolled back to DXKM3, I read no less than 6 different threads here about flashing/rooting/unsinging, that is not yet counting the external forums I visited for the firmware... I suggest you do the same, even keep the pages open while flashing so that you can revisit those threads when needed... That's what I did the first time I flashed with the Motorola E6...
[Galaxy Tab Q&A, Help & Troubleshooting] bongski55:
The best step by step for me is the one for the overcome rom. I even have printed it including the tips and tweaks for reference. Just substitute files.instead of.the overcome.files on the steps.
[Galaxy Tab Q&A, Help & Troubleshooting] dimedropper:
Used the steps provided by noxxious as well as the download file (P1000DXJK2). I am using Odin3 1.7. I place the tab in download mode then placed the .pit file and .tar file. Checked re-partition and hit start to flash.

My tab go stuck with:

<ID:0/009> Setup Connection and the digging Android.

UPDATE: After removing the tab, I got a cellphone triangle/exclamation and a computer. Tried doing a hard reset (power + volume up) but the reboot doesn't work. I still get the cellphone+computer logo.

What went wrong?
[Galaxy Tab Q&A, Help & Troubleshooting] noxxious:
it seems that the connection has timed out or loose connection with the usb??? :confused: have you tried with other usb ports?
[Galaxy Tab Q&A, Help & Troubleshooting] dimedropper:
Looks like my first download of the file was corrupted. I did another download and the old file was smaller than the new one that I just downloaded. I ran Odin again using the same steps you provided and Odin did its work (yey!).

Follow up question: If I did a back up before going back to Froyo and run a restore via Kies, do I get all the apps and setttings back? I think I'll be able to retrieve my contacts, music and videos.
[Galaxy Tab Q&A, Help & Troubleshooting] Lhon0901:
You seem to have gotten the error I mentioned earlier...

Okay, to save you the work of looking for the fix, you get that error when flashing the TAB from a signed one with unsigned one... Just flash with a signed bootloader and you're good... Use the DXKM3 we posted here... It's better if you use the first DXKM3 firmware I posted for it's already rooted and unsigned... Now, after flashing you might not have any values on the PDA and CSC, just flash with DXJK2 then back to DXKM3 with the md5 files...

That should fix your TAB... As long as odin detects the phone you are fine...
[Galaxy Tab Q&A, Help & Troubleshooting] dimedropper:
^Was able to make it work with DXJK2 file. But after connecting it back to Kies it's saying that my device cannot be upgraded. I thought there was already an Asian version of the GB that I can upgrade to via Kies.
[Galaxy Tab Q&A, Help & Troubleshooting] noxxious:
i haven't tried using kies to do my backups when i flash my tab, i always use titanium backup and it does it for me.. :) though im quite sure apps aren't backed up by kies.
[Galaxy Tab Q&A, Help & Troubleshooting] dimedropper:
^Yup they are not backed up. I had to download everything. And when I upgrade to GB Asian ROM I will need to get my apps again.

Any other way to upgrade to the Asian GB ROM without going through Kies? Kies is saying my tab doesn't have an update.

I think its because my CSC is JJ2???
[Galaxy Tab Q&A, Help & Troubleshooting] noxxious:
is your tab reporting your PDA MODEM CSC version correctly when you do *#1234#?
[Galaxy Tab Q&A, Help & Troubleshooting] cymagnus:
What CSC did Kies report your tab's firmware as?

Is it CSC:JJ2 (XEU) or just CSC : JJ2 ?

If both is the case, need to change your CSC to your country's by dialing *#272*<your imei number>#*. Think Philippines is XTE

I think my tab's screwed. Its working but I think I messed up the Phone and CSC files.

@noxxious - when you say "correctly" what do you mean? Are they giving out the same info? I guess not.

UPDATE: I changed the CSC code to GLB (which I found out in another forum is GLOBE PHILIPPINES) using the instructions from cymagnus. My tab rebooted (erased all the apps that I downloaded...again!) but this time Kies recognized an upgrade to GB Asian version. Upgrading now.
