[Q] Bricked after upgrade attempt

Hi!
I was trying to upgrade my Galaxy Captivate following the instructions on this thread http://forum.xda-developers.com/showthread.php?t=783403
First I tried the KIES option, but ended in the phone stuck on a black screen after 2 minutes of the S logo on it.
So, I then tried with ODIN using both package, first with the original, but ended getting an error "E:Can't mount /dev/block/stL10 (Invaild argument)"
And then with Richthofen's integrated package which seems like fixed that issue. indeed did it, but not fixed the original issue, after this one I ended in the same stage than with the KIES upgrade.
I can enter on recovery mode and move using the volume up and down button, however, the "power" button to select any of the option do nothing.
I tried to connect with adb and indeed see it (when is on recovery mode)
adb devices
List of devices attached
10004cb6cc04 recovery
But can't do anything on the phone, not even reboot it with adb, the process get's stuck and the phone is not rebooted.
Anyone have any idea of what I can do now? send it to Samsung is not an option since I bought this phone in USA and I live in Argentina, this phone is not available in the country yet.
Thanks in advance.

Thread moved to Captivate Q&A.

You used a rom with a kernel for Samsung Galaxy I-9000, I went through this also. The I-9000 has a "hard" home key and the kernel is telling your phone that it does also. Are you sensors acting backwards; up/down = left/right?; if so you need to flash back to stock with Odin 3 http://forum.xda-developers.com/showthread.php?t=731989
I was able to get into download mode by using the vol key like it says but I repeatedly tapped "menu" and "Home" when the little triangle kept popping up (I mean really fast tapping) and it worked. It's really hard to brick these, thought I did more than once myself.
Follow the instructions, it works great. I've had too use it more than once.
Lesson here, don't use any package that's based on a kernel for different hardware; especially the I-9000; unless specifically stated that it has been modified specifically for your phone.

http://forum.xda-developers.com/showthread.php?t=731989 saved my life! I was so angry with me for being such an idiot!. I lost all the contents on the phone, but at least got my phone working again.
By the way, to put it in download mode what I did was, remove the battery, put it back, press volume up + down and plug the phone to USB.
Thanks a lot Tazman171

No problem, just passing on info that was passed to me by helpful people at this sight. And yep, the way you did it was right, I was thinking of the recovery menu and selecting reinstall packages option, I actually was able to do it with the way I described above.

Hey right now my phone is "bricked" because of a botched JPC Froyo ROM install and I have no way of getting it into download mode. None of the methods on the "One-Click Stock ROM" work, and a few other ones suggested don't either. I'm curious as to how you did it with tapping menu and home, etc. Would you mind posting up some instructions?

Sorry about the late reply, it was recovery mode that I got into, not download mode. You might have one of the phones that won't support the 3/2 button methods of getting to the download/recovery menus. It worked for me because my phone does support that method, it was just the I-9000 had switched my buttons around.

If you're able to provide information as to exactly what you did to get your device in this state that would be immensely helpful in regards to diagnosing the problem. However you'll probably be able to recover your device using a custom jig.

I can not be more explicit. I wanted to try a rom. Wasn't satisfied so i downloaded another one (with cache file, database file, bootloader, etc... ) but the file have been dowloaded too quickly (i think the zip file was corrupted...)
So i did the flash, and my tab don't wake up. I don't have a brick state (with the usb and pc logo). I don't have the samsung/galaxy tab logo. Ihave nothing on my screen. Like my on/off button was broken...
And whatever i do(like the combo on/off with the volume down), my computer don't recognize the tab. So i can't flash it again.

Well you're going to have to be if you want anyone's help.
What files did you flash? Which software did you use? Which version? Were you given errors? How did you flash the files?
Please provide a detailed step by step run-down of exactly what you did.

I can't remember, and i'm french, i can't find the right word to explain the situation...
I flashed my tab with HEIMDALL (the last version on the website) i think the problem is when i wanted to flash with the file EURO.pit (i choose this file in the "bootloader" category of the software HEIMDALL).
The problem... My computer can't recognyze the tab because i can't turn on the tab, so... I don't know what can i do.
EDIT: And HEIMDALL don't tell me any error. Just "Flash Complete, Rebooting"
EDIT 2: I think i used the wrong bootloader...

Up?
What can i do? Is a batterie problem?

Let your Tab charging for 5 Hours and then try again.

Sounds like you've flashed a bootloader not designed for your tablet. Luckily all Galaxy S devices store a backup copy of the secondary bootloader which is utilised when a certain resistance is detected on the USB port. You can send it off to Samsung and they'll repair it, but they might charge you. The other option is to build your own custom jig which will activate the backup secondary bootloader.

now ive got the same problem. i tried a custom recovery i found in the "bible" sticky...clock work wasnt working when i was doing adb commands. the recovery i tried is called 3e. all it would do is reboot, t-mo logo and then bootloader words would flash very quick and black screen (backlit) press the back button and i got the triangle droid.
then i got it to go into download mode and tried a rom with odin this is the rom if it helps
GT-P1000_P1000XXJME_P1000OXAJME_P1000XXJMB_P1000XXJME_XX_ITV.zip.enc
unzipped, selected in pda and clicked start. failed at the last second and the downloading android screen on tab was stuck so i powered it down.
stupid stupid stupid!
now it wont turn on period, i get nothing from usb connection or secret button presses.
ill try the "rig" tomorrow, but how will i hack up this galaxy usb to work? the guide says micro usb but obviously thats for a phone.
please help if you can, i just got this thing today

@Benjamin: I can do a custom jig for a galaxy tab?
EDIT: But i don't think the jig will help me..
"If your phone screen is always black, that is it does not display the white Galaxy S/Samsung/AT&T logo when you switch it on, then sorry, this jig will not help you. "

HELP please? Can i do a custom jig for the galaxy tab? And How?

press and hold the power button for 10 second make sure it totally off
then try to enter download mode
if u are able to enter download mode
flash roto jme v4
if it a battery problem
i think it may be battery flat, try plug it in to the charger see if it work after 10 min

help bricked phone

Hi everyone. Im not normally in this section as i have an x8 but my friend has seen all the roms,mods and updates ive done so he tried to do it to his galaxy s i9000 without rooting or unlocking his bootloader. I asked him what he did he said he just tried to update software with keis but now it wont turn on just white screen with a red triangle in the middle i hope its download mode as i dont have a galaxy i dont really no but the battery has died and it wont charge im guessing hes damaged the bootloader am i right and if so whats the best corse of action to tepair it. Thanks.

You can check if it is in download mode by pluggin it in pc with odin. See the wiki page what it says about soft brick.
Soft-Bricked
After flashing a rom you might not be able to enter the Download Mode by pressing Volume Down + Home + Power. In this case a so called 'JIG' would be helpfull.
You could build it on your own: [HOWTO] [REF] Get Download Mode without 3-button combo using homemade JIG
... or buy a preassembled one on a well known marketplace.Hint: There is no difference between a JIG for Samsung S/S2 or S-Plus.

See if you can go into d0wnload mode with vol down home and power. If that works go and try to find the stock firmware for the phone and download and extract. Download odin and put csc pda and phone/modem in there rightful places. 512 pit in pit section. Pit usually comes with odin download. If not find it somewhere. Repartition checked and hit start. It should reboot when done. It will problaby take a couple of min to boot but be patient. If it starts to go into boot loop put back into download mode again and reflash. Its very hard to mess up the phone to where you cant fix it. So relax and watch tuts or whatever helps you best. I know of a link i that i will find and post for you when i do.

DEAD bricked phone
So, my friend's phone (hopefully she'll stay my friend after this) was turning itself on and off all on it's own. So I (no good deed goes unpunished) suggested that I will upgrade her firmware for her. She had 2.3.3 firmware. I downloaded the odin1.7 as well as a package of all the info for 2.3.5 firmware upgrade. I flashed the phone- originally only using the PDA option with a file called: CODE_I9000XXJVS_CL565837_REV03_user_low_ship
It worked, the phone restarted and showed the firmware as being 2.3.5.
I don't know why, but I thought it would be a good idea to update the CSC and the pit and the modem as well- so I did that. when this was finished - though odin said that the flashing was successful the phone is completely unresponsive. The computer doesn't recognize it, it doesn't show any signs of life at all- like it's in the dark ages and there is no electricity in it.
HELP!!!
First question: do you think a jig will work? how dangerous is it?
second question: is there any other option to try that I haven't come across other than changing the motherboard, and if there isn't do you know where I can get one, bear in mind I live in Israel.
Please e-mail me a copy of the response to [email protected] if you can...

Odin dosnt pick it up atall plus the batteries dead aswell now and the stupid thing wont charge so i cant evan try any thing till i find away or some one to charge it but thanks for the tips.

Try to recharge the battery from other phone or use another battery.
Check whether you have the download mode working. (Home+Power+Volume down)
If yes, put phone in download mode and flash Darky RE or any other Rom via ODIN. Try to get the recovery mod after rooting and then try ROMs.
Or try restarting the phone it may work without update also. Long press power in download mode restarts the phone. However be careful.

What is the status of the device can you go to download mode
Post your firmware files name and how you choose in the odin flasher.
Dont try anything crazy you will bricked your device more:banghead:

Alternate way to Download mode
Hi gavster26
I have been there with a buddy's phone... not a nice place.
Found a link showing this other trick ... but you have to trial and error this one on the different combos:
1. Phone off
2. USB cable pluged in
3. Odin running
4. Down (or Up - test both) Volume button + Home button + plug in the USB cable.
This booted my dead "bricked" phone into download mode.
Try it.

i guess your gonna download a firmware on 2.2.1 and flash it..........but i recommend 2.3.3 firmware..try it on mine the ......!....... but still odin detects it......2.2.1 is old try AOKP for are tab....best rom

First, which tab is yours.
Edit: from your pm you indicate P1000.
OK, I sounds luke a broken record now but here goes.
Have you had a look at overcome method.
You need to flash GB-stock-safe-v5.
Sometimes even when screen is blank, it can still be a download mode.
So, be sure that it is charged (using original wall charger).
Then ready Odin and the files in proper places and pre connect the tab to PC.
Then boot to download mode and quickly flash using Odin.

one click unbrick tool in attachments (you need java installed for this to work)
i now have to flash cw and install that jellybean rom right away.

What about a Tab P1000N? What can be done with that one?

One Click Unbrick (by Adam Outler) is not a P1000 specific software.
It should work for P1000N too.

Problem with Tab S2 T815: stuck in "Downloading Dont turn off target"

Hello
I was testing an auto reboot app in my tablet (cf-autoroot rooted Tab S2 T815) when it rebooted and it got stuck in download mode but as if I had initiated a new upload. No matter what I do, it doesn't reboot to anything else I have tried flashing various stock roms (even MM) ODIN sees it starts to upload but fails I dont know where to get a .PIT file to try and repartition. I have also tried pressing multiple button combinations to no avail Only by pressing Power and Volume down it instantly reboots to the same screen
Any ideas before I have to resort to official service (and be financially skinned)? All help will be greatly appreciated
Thank you

Problem is when I try to power it on, it doesnt boot normally. If I try to reflash a ROM (by pressing Home+Power+Vol) it shuts off (it seems that battery is at or near at 0%?)When I try to charge it, it boots instantly and goes to that screen again Have I bricked it somehow?
Thank you

UPDATE Somehow I managed to get it into "normal" download mode and ODINflash a stock ROM With 4% battery!!!! Anyhow now it seems to work fine When it'll be fully charged I shall make a full control
Any ideas what this incident was? Should I post the incident somewhere for future reference to any who might face the same situation?

PS Is, by any chance, there a way to untrip KNOXX counter that I have missed?

There is a BIG difference between "autoboot" and "autoroot". The app you tried to install attempted to ROOT your tablet. Had you used the Power, Vol Down and Home buttons BEFORE trying to download what were apparently the WRONG ROMs for your tablet, there might not have been a problem. But there is no telling what the cf-autoroot app did. (Except trip your Knoxx flag.)
If flashing the CORRECT stock ROM didn't restore Knoxx, then nothing will. But if you tell Sansung you "accidentally" entered the download mode and didn't know how to get out of it without attempting to download something, then they might honor your warrantee anyway. Just make sure you tell them you WERE NOT trying to root your tablet or install a custom ROM.

Knox has NOTHING to do with the incident Was tripped when I firstly rooted the tablet some months ago Just asked if there is a way of untripping it that I had missed

Well forgive me for misinterpreting your OP which stated "I was testing an auto reboot app in my tablet (cf-autoroot rooted Tab S2 T815)". That does say "cf-autoroot" doesn't it? My interpretation of that sentence was that the "reboot app" you were "testing" was actually "cf-autoroot". Can you possibly see how someone could make that mistake?
So what actually took place was that you installed an "autoboot" app on your rooted Tab S2, which was rooted via cf-autoroot, and when you tested, using the new autoboot app, it booted to a non-working download mode. When you then tried to flash a legitimate ROM via Odin from this bogus download mode, it simi-bricked you tablet. Is this correct? I have seen this happen when a multi-boot app tries to boot the stock recovery download mode when you have TWRP installed. Stock recovery download mode no longer works once you have flashed TWRP. The Power, Vol-, Home key combination will exit from the non-functional stock download mode.

Well "cf-autoroot rooted Tab S2 T815" was in brackets and AFTER "my tablet" wasnt it? Anyhow, I can understand misreading, no worries
Pretty much what you describe, yes. Differences: A. I had never installed TWRP B. Still dont know how exactly I managed to get it to "normal" download mode! I had managed to shut it down with the button combo you suggested only to find out that it was almost out of battery Trying to find a way to charge it, it started rebooting even after pressing "your button combo" In the effort to stop that I got in "normal" dnload mode again Without losing a second flashed the first stock ROM I've found on my HD and, voila, it was up and running After I had it charged I flashed MM(it's blazing fast Way faster than Lolli) and rooted it with cf-autoroot Everything seems to go smoothly now
I'd like to come to the bottom of this and post problem and solution to the appropriate thread as I havent found any other references and it might occur to somebody else (that app has over 100K of downloads)
I thank you once more

Most of what I've read was user error.
You obviously selected to boot to download mode from the app.
Nothing wrong with that as that is exactly what it did. Nothing bogus about it.
The problem started when you panicked and ended up half flashing something with a flat battery.
All you really needed to do was hold POWER + VOL DOWN to exit down load mode.
You would have rebooted just fine. Your OS would have still been intact.
You eventually got to 'Real' (as you call it) download mode by pressing the right button combo after at least getting some charge in the device.
