Use this method if you are not familiar with ADB:

Plug your Tab via USB to your PC so that the internal SD card gets mounted (you should see a new drive, where you can read and write files).

Copy "JMG_recovery" (from the ZIP archive provided in the discussion thread you mentioned: http://xdaforums.com/showthread.php?t=930590 ) to your internal SD card, rename it to "recovery".

Unplug USB.

Make sure your Tab is rooted, and install RootExplorer from the market.

Use RootExplorer to copy "/sdcard/recovery" to the "/system/bin/" folder on your Tab (this will OVERWRITE the original "recovery" file, so you may want to make a backup beforehand). Don't forget to click on the "r/w" button in RootExplorer, which should then change to "r/o", otherwise you can't write data in the protected "/system" folder.

Reboot in download mode, use Odin to flash the multi-CSC TAR file.

Your Tab should then reboot in recovery, and this time it should install the CSC fine (the patched 3e "recovery" doesn't check for the "update.zip" signature, thus why it works).

[Galaxy Tab  Android Development] m11c3:
just make sure

after extract JMG_recovery got 3 file : JMG_recovery.txt, JMG_recovery, JMG_recovery.i64

just copy JMG_recovery only, right?

copy to sd card, then copy to /system or /system/bin?

cause file recovery origin in /system/bin

in market no any rootexplorer but i installed super manager

then i follow your step rename to recovery then cut overwrite to /system/bin

after it no any button r/w & r/o

then i reboot, put download mode, result still signature verification failed

*try to install rootexplorer.apk
[Galaxy Tab  Android Development] daniel.weck:
Sorry, /system/bin/ is the correct location ! (I fixed my post)

Hello,

I am kind of stucked. My Galaxy Tab won't boot anymore. I can go into download mode and flash, but it still hangs at the first screen after reboot. I think it could have something to do with the bootloader. I know, flashing the bootloader is a risk, but since my Tab doesn't boot anymore anyway, why shouldn't I take the risk to flash the bootloader. Well, the questions is, where do I get one. The apk contains sbl.flash. Is it the same as Sbl.bin? Can I flash it using Heimdall?

Have you tried flashing another kernel ? You made a backup, right ? ;)
[Galaxy Tab  Android Development] loonyt:
Well, I couldn't make a backup in the first place because when I first flashed the device nothing worked at all. I am thinking it could be a hardware defect, but I am not sure. However, I will try a different kernel. Which one do you suggest?

loonyt
[Galaxy Tab  Android Development] daniel.weck:
By the looks of things, you need to flash a Samsung ROM before "upgrading" to custom builds. This would be the safest path, because it would repartition / reformat your device, and you would start from a clean sheet. Good luck !
[Galaxy Tab  Android Development] loonyt:
Is it GT-P1000_P1000XXJK5_P1000OXAJK5_P1000XXJK5_P1000XXJK5 _XX_DBT.zip?
[Galaxy Tab  Android Development] daniel.weck:
I'm not sure. You should start a new discussion (in the "Galaxy Tab / General" section) to ask the broader XDA membership. Don't forget to mention the country/shop you bought your device from. Cheers, Dan

roto jmi e patch ?

Hello, I wanted to ask very nicely (I've read every post) if the patch to work on bootloader roto JMI? I first signed by the bootloader, or perhaps the jm6 jmc, now I have a roto-JMI and patches seem to be compatible but have not tried it because I fear the block, tips? I wanted to put the kernel 1.2 tank.
[Galaxy Tab  Android Development] rotohammer:
It should work just fine, the fix does not depend on the version of your firmware.

No support for Docomo SC-01C

Hi,

I just bought a Docomo SC-01C variant of the Galaxy Tab, and wanted to try this app on the unit to determine if it's safe to flash ClockworkMod recovery and custom firmwares on this device. However, when launching this app it tells me "Your device [SC-01C] is not supported."

So I don't appear to have an easy way to find out what bootloader I have. I can see the following details in my device details:

Baseband Version: SC01COMJK2

Build number: FROYO.OMJK2

But don't know if these details are a reliable way to determine bootloader version or not...?

EDIT: I don't have a locked bootloader as I've managed to flash some kernels now, muhahahaha! *world domination laugh*
[Galaxy Tab  Android Development] Squishie:
Quick question for Roto or Chainfire:

I'm running Roto-JMC V1 on my tab, I don't have signed bootloaders however I do have a signed zImage, I'm looking to install Overcome with Modaco's ext4 kernel and I'm wondering if I'll run into any issues flashing the customized kernel.

(On a side note, said kernel includes a cifs.ko, fuse.ko and tun.ko in an optional package, where on the device do I place those files for proper functionality?)
[Galaxy Tab  Android Development] abuser0815:
If you have no signed bootloaders you can flash any kernel you want. no problem it all. if you let the bootloaders untouched, you will be able to get everytime back if you want.

in the case of overcome rom you have to flash before the kernel and let the system convert into ext4. after you can flash overcome. if you wanna go back to rfs, just flash rotos jmiv2 full as pda in odin together with the p1hidden pit and you will be back.
[Galaxy Tab  Android Development] rafaelwv:
Hi!

I tried out this ROM. Whyever my tab froze (it went smooth for 3 weeks or so) and when I did the reboot it didn't boot up. I then tried to reflash it. Then it got stuck in the "cellphone & computer" screen.

I tried to reflash with stock firmware. Ok and PASS. Then reset and it got stuck on the Samsung bootscreen. Nothing happens. Next step: I tried to flash rotohammer latest firmw. Same result.

Is there a way to revert EVERYTHING back to stock, including kernel, partitions, format...?

Problem is: I seem to have the protected bootloader, but I can't boot up to unlock it again... what now?

Regards,

Rafael
[Galaxy Tab  Android Development] abuser0815:
you can try out the jj4 rom. you can find it on samfirmware. it seems to be a complete rom with unprotected bootloaders.

BUT, if you have protected bootloaders now on your tab it will not work. but you must be able to flash roto´s jmiv2, because it contains the signed kernel.

so i suggest to you, download roto jmiv2 full (not the upgrade version) again (perhaps your other file is corrupted) and also the p1hidden.pit .

you have to have odin 1.7. select the p1hidden.pit and mark repartition and also select the new downloaded roto jmiv2 full as pda. that way it should work.

Hi all,

can somebody tell me if the JK5 firmware downloaded from samfirmware is locked?

i thought that the lock applies to JM6 upward firmwares....is it?

thanks in advance

i try to flash the ZHKA1 ROM for many, but it also "FAIL" when is flashing to zImage step (the last step). Is it normal? But check the ROM by *#1234# and found the ROM already is ZHKA1. How to flash the ROM without error? Thank you.
[Galaxy Tab  Android Development] abuser0815:
jk5 has unsigned bootloaders.

@ all, if you are trying to mess around flashing any firmware from samfirmware you will end up bad.

make the following:

do not take jk5 from samfirmware, take jj4!

if it fails to flash, you probably have signed bootloaders. now you have to go to a stable version.

download roto jmiv2. flash it together with p1hidden pit. after your tab should boot, just give it a little time, be patient. if it is still on samsung logo after 30mins try enter recovery mode and delete cash and try factory reset.

rotojmiv2 must be flashable in EVERY case. with this you have a good base to apply chainfires tool.

if you don´t know or if you are not sure how to flash, look for tutorials. you will find it in this board.
[Galaxy Tab  Android Development] Neubi:
hi,

i tried to flash the JJ4 from samfirmware without success (samsung logo stuck forever) .. i think i've the protected bootloaders

than i downloaded the roto JMI-Full-V2 with the P1_hidden (first "Re-Partition" than flashed JMI) ... flashing itself was successful, but the tab stock at the samsung-logo for more than 30minutes ...

Q: when you mean "recovery mode", you mean Vol+ Pwr .. where the green/yellow working android man is shown?

Q: delete cash + factory reset: how to do this?

... f* ... hope i'll get my tab back to life!

many thx & br,

andy
[Galaxy Tab  Android Development] Chainfire:
"Recovery mode" is VolUp + Pwr (+Home in some cases). The yellow working man is "Download mode" (VolDown + ...).

In recovery mode you have options to wipe cache and data (you may need to go into recovery mode twice, it may reboot in between). Go there, do the wipes, try booting your Tab again.
[Galaxy Tab  Android Development] Neubi:
thx for the quick response ... but i can't get my tab to the recovery mode

tried: VolUp+Home+Pwr, with/without powercable, different combinations of keys, press/released some buttons during different actions but without any success??!

i can easily get the tab to the download-mode, but no recover mode?!

also google isn't really helpful at this point!

br,

andy
[Galaxy Tab  Android Development] Chainfire:
What happens? Does it keep rebooting? In that case you need to let go of the power button earlier.

I've never heard of a Tab that had recovery mode disabled.
[Galaxy Tab  Android Development] abuser0815:
There were some kernels around with recovery broken.

@neubi

Download the full version of rotojmiv2 and then flash it together with p1hidden and repartition marked.

Important is that you use odin 1.7

If you get again the yellow sign, just flash pit alone again. After it should boot.
[Galaxy Tab  Android Development] Neubi:
- VolDown + Pwr = downloadmode every time (as expected)

- VolUp + (Home +) Pwr = "GALAXY Tab .. SAMSUNG" logo

i've to press the pwr-button for about 2sec until i see the 1st response on the display -> than i release the pwr, but keep the VolUp(+Home) pressed for about 10sec .... but the samsung logo stays forever without any bootprocess or similar!

thx!!

andy
[Galaxy Tab  Android Development] Neubi:
@abuser0815: thx for the tips - i successfully flashed the rotojmiv2 with odin 1.7 and P1_add_hidden.pit. after the flashprocess finished the device restarted back to the samsung-logo.

than i flashed just the pit alone, but also can't start the recovery-mode!?

i restarted the tab via the pwr-button and i'll wait for 30min and check if the samsung-logo disappears (hopefully)

so long, thx,

andy
[Galaxy Tab  Android Development] Neubi:
f* .. everything i try results in the samsung logo - and this logo won't transform in any kind of bootprocess ... and i still can't start the recoverymode ... :mad:
[Galaxy Tab  Android Development] Manicova:
@Sandra

I'm not as good, but I think if you see the samsung logo its not the pit, the problem! is it the animated one r the first white one ?
[Galaxy Tab  Android Development] abuser0815:
thats really really weird. i´m with my latin at the end. perhaps a hardware failure. where is your next samsung service center? sorry that i cant help you out of your situation. because rotojmiv2full normally has all onboard except the bootloaders. and the kernel is rsponsable for recovery. just to make one thing sure, switch the device of ( make sure its of, a short press on the on button should not cause anything), then hold volume up button and press power on button. as soon the first samsung screen appears release the power button and maintain the volume up button pressed. if you get again into a kind of bootloop, it might be possible that your volume up button is broken, at least a possibility....
[Galaxy Tab  Android Development] Neubi:
thx guys for you support!! ...

but the tab stuck on the first white, not animated samsung galaxy-tab logo

- short Pwr pressed: nothing happens (normal, as expected)

- VolUp + Pwr(2sec): white samsung logo - stuck forever

- VolDown + Pwr(2sec): yellow download android

- VolUp + VolDown + Pwr(2sec): android logo ... "POWER RESET or UNKNOWN UPLOAD MODE"

... so IMHO it seems that both volume-keys are working!

.... what i did:

- europe version without any simlocks, brands (bought via amazon in october 2010 as an "early adopter")

- updated via Samsung Kies from ??? to XXJK5 in december 2010

- i've not installed and executed the SGT bootloader-patch from roto!!

- downloaded P1000XWJMI from samfirmware

- Odin 1.7, P1.pit, download failed (can't remember if i was really using the correct pit and odin versions)

than i tried to switch back to JI4, JK2, JK5 without success

meanwhile i tried JJ4, JJ7, JM1, JMG, JI5, JK2, JK5, JM6, roto JME, roto JMI, JMA, JMB

thx & br,

andy

Before i flash my tab with overcome rom by alterbridge my rom is JJ3 asia.

And i successfully flash overcome rom and kernel, i just followed the instruction and it went well.

Does this means that my JJ3 rom is unsigned?

I did not follow alter's instruction to flash to stock rom before flashing overcome.

Now, i wonder how will i go back to my stock rom? Will i simply follow his instruction to use JME by rotohammer?

Thanks.

Hi just wondering about this patch is there no way you could adapet the bootloader patch so it could be flashed to bricked tabs through odin

Just mine is bricked and i think its bootloader locked as theres no recovery mode only download mode so if there was a way to flash the unlocker to bricked phones then the tab would take the full flash and boot up as normal

Now that would be cool and save me and others like me loads of greef:confused:

Unlocking Bootloader

Hi guys I feel a bit stupid but since my head injury last yr i just dont seems to be able to think as good as i use to and so to my question.

I have a GT-P1000 non branded euro Galaxy Tab with Baseband P1000XXJMA with build #: FROYO.XWJMI (purchased from optus in australia post-paid) and I have downloaded the bootloader program on the first post and installed on me Tab, I have rooted the file system. Im not sure weather to run it or not as in the first post it say if ya have JM version there is problems. Is this still correct and if not can i go ahead and unlock the bootloader.

Also I would like to know which Kernal to put on it now there are so many and i cant workout which ones are safe or not.

I almost bricked it the other day, took me two days to get it up and running again on origonal software.

Galaxy Tab bootloader 3e problem

I have a strange problem with the bootloader of my T-Mobile Galaxy Tab. It is unlocked with the app in this thread successfully and I can flash a new firmware such as stock 2.3.3 or the european 2.2.1 via Odin. However, whenever I boot into the Recovery screen, I get stuck there. The bootloader gives me the error:

.....

E: Can't mount /dev/block/mmcblk0p3

(No such file or directory)

E: install_application_for_customer: can't mount HIDDENSDCARD

....

I can not reboot or wipe data, because the menu selection doesn't do anything. The only way to fix it is to use odin to reflash whatever was running and restore the application. This is very frustrating and I already spent time searching for the answer and couldn't find anything. Can anyone point me to the right fix for this bootloader error? Can I flash the previous version of the bootloader and how?

Thanks so much.

Need help to recover T-mobile Tab (SGH-T849)

Hi guys, hope you can help me out here.

Just got 2 T-mobile tabs with no firmware on them. I can get into download mode and have required drivers installed, ODIN can see the device.

I tried flashing JPJM5 before bumping into this thread and the process failed at the "hidden" part in ODIN. Rebooted, got the phone--!--PC black screen, then flashed pit file alone and able to see download mode again. Tried to flash a different version XXJQ1 and got the same results.

I'm not sure if I'm facing the protected bootloaders issue and I don't mind having the JM* version as long as the device is functional...

Anyone knows what I can do here to be able to successfully flash a any ROM?
[Galaxy Tab  Android Development] studiozeroseven:
Sup, Yes since you flashed any of the JMx (x = anything) you have run into this problem, heres what I did:

Reboot the devices into download mode (You will still see the PC---!---Phone) but it will be in DL mode

Now flash this

(You should be able to boot everything just fine)(if not let me know)

Now apply the patch located within this thread

Now you can flash any other non-JMx rom, Just remember to not flash JMx again cause you will have to do this all over again.

I hope it helps!
