Buenas noches.

Did you do somehow a rotobackup before you flashed your vodafone brick?

If yes, could you post your backup files? I'm in same situation, but i could flash older firmwares with heimdall. Its a bit tricky but it was possible.

Best regards/ saludos!

All signed for me as well, my firmware is coming from samfirmware..
[Galaxy Tab  Android Development] pakalrtb:
@Whowith : the simple answer is NO. Currently no official FW seem to have the signatures required by the Bootloaders you flashed with your JM6 FW. Why these experimental FW have impletemted a signed BL is unknown. Speculation tend to think that signed BLs will be used by branded versions of the tab , in order to prevent the flashing of custom FW.

[Galaxy Tab  Android Development] WhoWithTheWhatNow?:
@abuser0815

Nope, didn't make any backups (now just HOW stupid was that) but at least my Tab is not bricked, so it ain't so bad!

@pakalrtb

Thanks for answering so quickly. The only reason I asked was that reading all 16 pages before I posted, I did read the if you used the "old" JM6, downgrading was possible and since the steps I used were posted Nov. 30th using a package the poster said was found here at XDA, I thought that maybe, just maybe it could be the old one and I can go back to the old firmware.

I dunno know if I can post the URL leading to where the rar file containing the JM6 and the components used to flash, but if it helps, I will surely post it...who knows, maybe I do have the "old" JM6 and can go back to an official.

I would try reflashing to an older FW but I dunno if it can brick my Tab and if it does, I have no idea how to rescue it.
[Galaxy Tab  Android Development] rotohammer:
I believe yes, you can downgrade, most of the folks who flashed JM6 did not get the protected bootloaders. JMA,C.D.E are the the real problems. Try running Chainfires test to be certain.

I'd hold off flashing until we get it all sorted since everything is working fine for you.
[Galaxy Tab  Android Development] WhoWithTheWhatNow?:
@rotohammer

First off, I gotta say, reading your posts, you are the man!!! You really know your stuff and put yourself in the front line.

Second, I would have tried running Chainfires test, but reading on how to do it, I found it very confusing and to be honest, being a complete "noob" on the subject, didn't understand a word of it nor how to do it, lol!

If someone could explain "noobstyle" on how to do Chainfires test, it would be great for us who are new to all of this (especially me).

And third, I have read the there are special version you created of different FWs. Could I use those to update my FW and , if confirmed I can downgrade, do it when Gingerbread (or some new official FW) comes out?

Sorry for asking so many question and I do hope I am not off topic just trying not no brick my Tab and as well, trying to get it as up to date as possible (seeing as the FW i originally had, well, to say it sucked is putting it nicely)

Thanks again for all the help to all of you.

Update:

Just saw the last part of your answer and will do, I will hold off flashing for now until you guys get everything sorted. Again, on part of all the noobs like myself around here, thanks for all the hard work!
[Galaxy Tab  Android Development] rotohammer:
Hang tight, someone will make it more clear soon I'm sure

Yes, if you have the unprotected bootloaders, you can up/downgrade all you want after flashing my firmwares. If you have protected bootloaders, you can still flash my firmwares, they wont make anything worse, just get you up to the latest firmware that works good.
[Galaxy Tab  Android Development] abuser0815:
ok, but your tab is working right now ;-)

i just called it a vodafone brick as the tabs distributed from vodafone in spain are with netlock on.

@all,

call me kamikaze, but i´m trying to downgrade again, just to proof that it's possible.

with chainfires tool i got those readings as well:

boot.bin: SIGNED !

sbl.bin: Unsigned

zImage: SIGNED !

actually i have on the tab:

PDA: P1000XXJMC

PHONE: P1000XXJMA

CSC: P1000OXAJMC

kernel 2.6.32.9

root@sei-27 #1

build froyo.xxx.jmc

will report later if i bricked my tab or not.

i do it, because i believe, that i have done it before, as i was at the same firmware befor as well.
[Galaxy Tab  Android Development] rotohammer:
With an unsigned sbl you should be able downgrade.
[Galaxy Tab  Android Development] abuser0815:
what i understood from chainfire, that even if boot.bin is signed, its not possible to downgrade....?

also i had this firmware from samfirmware. so if i should be able to downgrade, i´m a bit confused, did somebody report all 3 files signed? (sorry, came back late and have not readen all posts into the very detail)
[Galaxy Tab  Android Development] rotohammer:
I'm just placing a wager that it downgrades, but don't let that stop you from running the test :)
[Galaxy Tab  Android Development] lux209:
Strange my firmware is also coming from samfirmware and my sbl is signed, I received my tab with jk5 then upgraded to JMA and JMC.
[Galaxy Tab  Android Development] Chainfire:
I'm not sure whether it should be possible or not with Unsigned SBL but Signed PBL. However, if you look at these two posts by paulshields:

Also @rotohammer: http://guide-images.ifixit.net/igi/h5GYlFtNW5BMQhHo.huge ... dissembled Tab without JTAG points? (or perhaps just coated)

[Galaxy Tab  Android Development] abuser0815:
ok, i finished messing arround with flashing firmware and have put back my backup.

result:

with heimdall i was able to flash everything, I had provider firmware from vodafone, i had jk5 and befor jid.

what was very curious, with every firmware on, it says with chainfires tool that primary bootloader is still signed. i got no difference. strange. it seems, that even if you select the different bootloaders in heimdall that the signature keeps on. just like not flashing complete to the end.

every time with jirmware lower than jmx, heimdall did finish, but the bootscreen stopped at aproximately 90%. just bring the tab again in download mode, it shows at this stage just tab--warning--computer and flashing with odin an adecuate pit brings the tab back to life and it shows the correct firmware.

only with odin you cant flash any zimages, i gues for the bloody signature. so i guess, if somebody get the primary bootloader on the tab without signature the problem will be solved.
[Galaxy Tab  Android Development] RWOLUPO:
yes, my files are all signed ...
[Galaxy Tab  Android Development] FredBE:
With my bricked Tab back from RMA: both sbl.bin & boot.bin are unsigned now (they didn't flash the JJ3 firmware I put on it before bricking neither did they repartition apparently).

I got some Kies upgrade compatibility back but not perfect:

What is strange is when I flash an original JJ3 firmware then try to upgrade to JJ7 with Kies: everything works fine till the flash hangs at 50% on the Tab downloader bar.

I flash JJK5 with Odin and all is fine now but I wonder... Is it some special .pit file we don't have for the original JJ3 ? no idea (I tried p1_add_hidden : hangs at 50%, 909 gives a Kies upgrade error message at 50% and 816 doesn't allow to flash JJ3).

[XPERIA X10 Q&A, Help & Troubleshooting] jvx300:
So i received a x10a as a xmas present. After doing much research i decided to debrand this phone by following the direction from this video:

http://www.youtube.com/watch?v=wacg-dsx9ew

I downloaded the GENERIC 2.1 x10a firmware from this thread

http://xdaforums.com/showthread.php?t=825201

after i was done flashing, i noticed that my camera wasn't working anymore...it would boot into a black screen and after a while i received a forced close message. Then if i try to access the camera with the camera button, it shows a message "camera not available" so i tried to flash it with multiple different versions of generic 2.1 firmware with no luck.

After reading many post about the camera not working i believe it's a defective camera,this is when i decided to flash it back to the original at&t firmware (so i can take it back to the store and get a new phone with a working camera) using the files provided from this link:

http://xdaforums.com/showthread.php?t=872298

now when i boot up my phone i all i see is a ! inside a triangle and the phone icon...what should i do???

thanks for all the help in advance

edit: finally was able to flash it back to AT&T with a rather strange procedure. I used the non-gui flasher to first flash in the 1.6 AT&T firmware but with no luck booting up. Then I flashed in the generic 1.6 firmware, surprisingly, when it booted up i saw the AT&T logo and all the AT&T app was in there. camera still didn't work, so i just took it back to the store and got a new unit. I flashed it again with GUI flasher, and now im running on nordic 2.2 generic firmware with all the features.

PS. does it matter if I am using a x10i firmware on a x10a phone? i did some research and only got mixed response, some say it doesnt make a difference some say 3G is affected. which one is correct????
[XPERIA X10 Q&A, Help & Troubleshooting] e3jeremey:
I could be wrong but it sounds like you've bricked your phone. I haven't heard of issues (going through the forum) of people having camera issues using bin4ry's rom. Its most likely from debrnding it and then the multipile flash attempts.

You're going to need some time and patience to fix it. Have you tried the repair function on the SE PC Companion software yet?

How do I enable the download mode? I Cannot find any answers in any posts just questions and more confusing jargon with no real explanations

any help would be appreciated

[Galaxy S I9000 Q&A, Help & Troubleshooting] ijaz__ahmed:
Some SGS sets have their 3-button recovery / downlaod modes DISABLED by the manufacturer. IMO the carriers ask the manufacturer to do so for them because carriers don't want us to install / flash new ROMs.

You need to modify the secondry bootloader of your SGS, if you want to permanently enable your 3-button recovery / downlaod mode.

To change the secondry bootloader of your phone, you need to put your phone into download mode, use Odin to flash the modified bootloader and you are done.

You will wonder how to put your phone into download mode when your 3-button recovery is not working !!

The solution to this problem is by using ADB (Android Debug Bridge). It is a piece of software which communicates with your phone at low level and can force the phone to boot in Download mode.

Well this is the overview what you need to do. For a step by step guide, you can search here or pm me. I can send you links on how to do it.

Hold down Home button that's the middle button + Hold down volume down button that's the bottom end not top .With these buttons held down press and hold the power on button until the Samsung logo appears .

Release Home Volume then Power button .

If you do not now get the yellow download mode icon you do not have download recovery .

I have some issues with a device I bought (coby internet tablet 7015) that have resulted in my being unable to use the android market (I always get a 404 error) or the app that came with it (appslib) I seem unable to install any apps (with .apk) because I do not have a file manager. I'm looking for a way to install apps without one, or maybe one I can install that is not in .apk format!
[Android Apps and Games] Andyt95:
Go into your browser on the device and find an apk for a file manager, then download it. when it's downloaded you should be able to open it through the browser. Then you can copy over an apk for ME (MarketEnabler) and install it. ME will let you use the market.
[Android Apps and Games] shoemeistah:
I wrote down some options:

1. If you rooted your phone and such you can just use adb from SDK

adb install [dir/package.apk]

(usb debugging enabled).

2. If you have internet on your device, upload a file manager apk you downloaded from a pc and put it where your phone can download it from with the browser. So when the download on your phone is complete you can click on the finished download in the notification bar and install it the file manager.

3. You can also try appbrain.

Though I think you should first fix the market problem. How about resetting the phone?

You can also use DropBox. Download the .Apk to your computer, pop it in your DropBox folder, open DropBox on your device, tap the Apk, and voila!

This error has to do with clockwork recovery from flashing cwr and getting an error. My error was when I flashed CWR and replaced the sd card! This cause me to boot into boot loops. Searching around on this thread and there are a few people with this issue and haven't found a solution.

This is what I did to be able to get past the mbr check sum error. Note I couldn't boot into stock rom with this error nor could I boot any rom besides the following!

Eugene no brick froyo...located on eb productions forum

I updated to Eugene no brick froyo, using Odin 1.7,

pit=512

Pda= eugene

Ran the process, and now you have a semi working rom, note I was unable to install anything or download on this rom. This is where I placed the CWR as and update zip (http://xdaforums.com/showthread.php?t=734164)

Reboot into stock recovery, REINSTALL package, this will locate the CWR "update.zip" was the name I used. It rebooted into stock recovery once again, and then reboot again into Clockwork Recovery. You now have CWR working,

Use the voodoo lag fix

1. CWM voodoo lagfix (http://project-voodoo.org/), placed on sd card and flashed through CWR

2. reboot

3. disable voodoo (disable it you just make a directory called "disable lagfix" wihout the quotes in the Voodoo directory on the SD)

4. Oden "no brick froyo" w/ repariton checked, now I had a working rom where I could down load items from the market.

I downloaded Rom manager, although probably not needed. I flashed the recovery in rom manager, just to see if it would work. It did work and now I can go from rom to rom, however I still have the mbr check sum error when I reboot into recovery.

Hope this helps out with this error, any suggestions in cleaning this post up let me know. THANKS TO ALL
