[Q] Stuck on Black screen

I have a Captivate that was rooted and working for over 6 months, and suddenly went into a black screen giving error on E:\.....
Have tried to install the stock firmware using ODIN in Download mode I897UCJF6-final-OCD-REV0 and I897UCKJ3_withBL and both are a success, but as soon as I reboot the phone i get the AT&T logo, see the Samsung logo and then the screen turns black and I can't even see the phone on USB
Also tried loading the Pinnacle_Flasher and I can see the CW recovery menu, but after that point I'm unable to flash an update.zip (Pinnacle_1.2.zip renamed as update.zip on root of ext SD card) from the external SD, and am unable to copy it to the internal SD Card. Connecting the phone to the PC says the USB drive needs to be formated.
Appreciate if anyone can help in recommending any other steps I can take to unbrick the phone

It could be something is corrupt on your internal SD card. Have you tried enetering clockwork mod and mounting USB storage and then hook it up to your computer and reformatting it

updated apps from the marketplace..

Did you actually name it update.zip, or just update?

i had the same issue. trying to look for the posts i made about it. i remember something along the lines of flashing to an old boot loader and an old kernel with cwm then doing all my wipes then doing a master clear via odin then via cwm again then tried flashing to stock. im probably neglecting one of my steps though.
oh and make sure you let it charge via wall plug for at least a half hour before you try anything.

o3d goes into recovery mode every time it boots

Hi guys, i'm in desperate need of your help. i think my precious o3d might have been screwed.
first let me tell you what i did. as you know the internal sd card of o3d is 5gb or so and it fills up very quickly. this internal sd card is mounted as /sdcard. i have a class 10 16gb micro sd card and when i insert it, its automatically mounted as /sdcard/_ExternalSD. The applications or games, especially the ones that have external data folders which are like 1gb in size insists to be installed on /sdcard. You can't move those data folders to _ExternalSD, because then the apps doesn't work.
Then i came across this topic:
http://forum.xda-developers.com/showthread.php?t=1189701
As you can see that was exactly what i needed. I had CWM 5.0.2.0 installed so i downloaded the first .zip then copied all of the files and folders excluding the _ExternalSD folder to the external sd card then rebooted into recovery. From there i flashed the zip and rebooted again. phone booted up and all was ok and it worked. now the phone sees the external sd card as the internal one and the internal sd card was mounted as /sdcard/_ExternalSD. I then formatted the internal sd card from the settings menu because i already copied all of the stuff there to the external card. It worked fine and the internal card is formatted. After that i decided to get a nandroid backup so i opened the rom toolbox program. From the menus i selected the backup option, gave it a name, clicked ok. the phone rebooted into cwm recovery screen but nothing happened. then i noticed something was not right because there was some error lines under the cwm menus saying "E:can't mount CACHE:recovery/command" etc. Then i selected the reboot phone option but the phone rebooted right back into the CWM recovery again!! At that point i knew that i was @#?^ed.
Anyways i researched a lot and came across this thread:
http://forum.xda-developers.com/showthread.php?t=1156549
i did exactly what he said and it worked, i mean it flashed nicely. then i rebooted the phone but it booted into the recovery again!!! But this time the CWM recovery was gone and i believe this is the stock recovery screen. I can browse the menu of it and make selections but the phone boots into the recovery every time it reboots.
The recovery screen looks like this:
http://farm8.staticflickr.com/7010/6654644033_b616bc0635_z.jpg
Then i flashed the phone to the latest official firmware V21A_00, it flashed nicely but it still boots right into the recovery everytime.
Then i installed the Android SDK and tried to push the original vold.fstab file to the system using the adb command line tool but it doesn't see the phone. I think adb works only when the system boots up normally, not in the recovery mode.
I don't know if there's a way to install the CWM from the stock recovery somehow. If you know how, please tell. The CWM has more options.
I don't know what else i can do. It started to look ridiculous. If there are any experts cool enough to help please do so. I'll be waiting. Thank you...
Edit:
I also tried this:
http://forum.xda-developers.com/show....php?t=1244490
I starts just fine but get's stuck on the "RESET" command, after a while it gives "DOWNLOAD FAIL!" error. I think the phone is supposed to restart automatically but it doesn't. Manually resetting the phone doesn't work either.
I'm about to pull my hair out...
Edit 2:
I also posted on the official LG Mobile forum here:
http://www.lgforum.com/forum/boards...d-goes-into-recovery-mode-every-time-it-boots
Fingers crossed

Quite a post!
From all your post there is no mention that you formated and did a factory reset after 21a flash.
Can you please try that if you haven't?

thank you for the reply!
i tried all 4 wipe options on the recovery screen then rebooted. it's the same, i'm back at the good old recovery again

Did you try with the external sd card out?
This is strange, usually a kdz flash coupled with a format fixes the problem.
Some how it still can't find the internal SD card.
I don't have further recommendations. Sorry

Hopefully someone else on this forum can suggest a way for you to unbrick.
your problem is although you have reset your phone, somehow it can't find a partition to boot from.
or
somehow the KDZ flashing is not totally successful.
good luck

If only there could be a way to be able to use the adb command from the Android SDK then i might be able to restore the vold.fstab file to its original, if the problem is that at all. Maybe then it'll work. To be able to flash the CWM Recovery again somehow might be a good thing too because it has more options like flashing .zip format roms but i have no idea how. Does anyone know if the stock recovery can flash some specifically named file to the system, does it have that kind of functionality? I'm desperate, please share your thoughts.

.............anyone?

I am sorry to say that but there is no solution for this problem yet. I have done the exact thing that you do and tried every single solution with no luck. The only way is to send it to lg repair service. My solution was to replace the mainboard.
Dostum gecmis olsun malesef tek cozum yolu anakarti degistirmek. Uzaman sayilirim android konusunda bosuna ugrasmayasin diye soyluyorum. LG servisi bile anca anakarti degistirerek cozum sunabildi. Temel problem internal karti formatlamis olman. Partititon table'i bozuyor bu islem malesef ve bu yuzden hicbir yontem ise yaramiyor.
Gecmis olsun tekrar...

so you say that the main problem was to format the internal sd card? well if formatting the internal sd card bricks the phone then why the hell is there an option to format it in the settings menu?

well if you didn't apply the swap fix, it wouldn't be a problem to format. When you swap the sd cards and format, it is the problem.

so you did exactly the same thing as me right? i mean you applied the swap fix then formatted the internal sd?
replacing the motherboard to fix this seems to be a bit nonsense to me to be honest. what does the partition table have anything to do with the motherboard?
if only there would be a .kdz format custom rom which factory resets the internal sd card during the flash process and maybe fixes the bootloader somehow, that might be the solution.

yes i did the same and the only solution was to replace the motherboard. we need a sowftware that can reach to the emmc in low-level. like omap flasher. but we also need the correct drivers which doesn't exist yet.

i don't know what the emmc is, i need to do research on that. but i still think that replacing the motherboard won't solve this issue because it seems non relevant to me. i messed up with the vold.fstab file. but after that it worked fine. i mean the internal and external cards swapped just fine. only after i decided to make a nandroid backup using rom toolbox all hell broke loose. i plan to wait a couple of days before turning the phone to LG service. i believe someone will come up with an idea.
yardım etmeye çalıştığın için teşekkür ederim bu arada

Well, there´s a new recovery for the O3D, v5.0.2.7 (I got it with ROM Manager).
It fixes 2 bugs of the previous (5.0.2.0) version: now the USB mass storage option in the mounts menu works (mount external SDCARD), and we can use ADB while in recovery. That way we can fix stuff in the phone filesystem while in recovery: we can now use ADB shell, or ADB push to replace files.
The problem is that I don´t know how to flash it to the phone while in the stock recovery. If someone can guide me on creating a signed ZIP containing this new recovery, flashable in the stock recovery, I would be glad to do that and post it here. I think these phones of you guys can be fixed using this method!

Great news! But now i need to find a way to install the new CWM. Just as you said i believe what i need is to find or make a .kdz update which includes this new CWM.
What do you think?

I know this is possible, at least for the Galaxy Ace: I have a ZIP file for this device with a custom recovery image, flashable in stock recovery!
To make one for the Optimus 3D, I need to know the following:
- How can I obtain the .IMG of the new recovery? I have found some temp files in clockworkmod folder in my sdcard. The creation date of one of them matches the exact moment I upgraded my recovery, and the file size also matches a recovery image: 5.54MB. Is it the recovery image? Can I just rename it to recovery.img? How can I extract it to ensure it´s ok?
- After I get the recovery image, I can use the Galaxy Ace ZIP as the base to build the O3D zip file. Any help on what do I have to change to make it work correctly?

Edit: I'm 99% sure that this isn't a hardware related problem. And LG's software not being able to turn the phone to stock is totally [email protected]#$%!

i tried all methods around here but not once i came across a screen like it. weird...

-HELP- flashed CM9 over the sd card....USB not working!!! -HELP-

So as you have seen from the title i flashed the rom over the sd card instead of the internal storage,so now i can't connect my phone to the computer to change the baseband,and i can't flash the original rom either,when i tried to restore trought the backup file,android as buggy as it is automatically selectet the "BACKUP" option and created a new backup with ICS ,so this is my dillema (i can't connect i to the pc to change the baseband and i can't flash the original rom),can anyone pls help me?my phone isnt even one and a half years old,
THANKS IN ADVANCE!!!!!!!!!

Flashing a ROM over the SDcard is not possible.
The computer just hasn't installed the drivers. Search for adequate USB drivers and it will work

it recognizes the sd,but when i remove the sd card and connect the usb cable it says that a phone is connected,but it doesn't recognize the internal storage

That's a feature for not allowing people who don't know what they are doing to mess up the OS.
If you want to modify apps on the internal memory use titanium backup or a file manager with root acces

so thgat's why even when i go into recovery th the pc doesn't recognize it?

What is the connection between recovery, ics , pc. Basically what are you trying to do??
As thatnextdoorboy said.. search and install new usb drivers to pc.
You cant access internal memory.. so dont think about it. You can use only Sdcard for storage.
First search for BBFIX patch in this forum.. "store" it in sdcard.. go to recovery and flash it.
Second read all the threads here about upgrading baseband.. and dont do it till you are sure of what you are doing!!

[Q] Help me figure out what's wrong

Problem
So i was running a slim rom and suddenly my device started rebooting constantly.
What i Tried
Wiping everything (System/Data/Cache/SDCard) booting into recovery and put jellyshot rom zipfiles on the sd card.
What happens now
When i unmount USB and try to flash the new rom, the files (jellyshot rom) aren't on the sdcard. When i mount USB again they also aren't on the card.
I have repeated this constantly and can't make any sense of it.
Is my device "bricked" ?
Thanks in advance.

volowi choose
Basicly whenever i MOUNT USB, delete and add files, the next time i MOUNT USB, the files are back in their original state. Known behaviour?

This is definitely not known behavior. To me it looks like you are getting write permission on the drive once you mount. So it looks to you as if file are getting deleted or files are getting added. But once you unmount/mount again, the changes are not done. It could be a problem with the recovery that you are using. May be try to flash a different recovery in fastboot mode.
Don't you have any other ROM on SD card to flash & boot. If you can boot in to the ROM, then may be you can see if you are able to correctly use SD card and copy a new ROM before you start wiping.

try format your sd from pc

No Mobile Network or USB Connection!!!
Hey I am pretty new to rooting but I have a major problem. I recently rooted my Samsung Nexus 4G, flashed clock work mod recovery and installed a version of Jelly Bean I found in on some website. But my problem is that I began to have problems with the version of Jelly Bean I download so I tried to flash back to stock but something went horribly wrong. Now my phone does not have mobile network and when I connect it to a computer, the computer will not recognize it. Bluetooth, WiFi and SD Card still works but I cannot find a way to get my Mobile Network to come back. Please Help!!

I'll install SDK, Odin, put the phone in download mode and flash a factory image. Just saying

Micro SD Card not detected in Recovery (Team Win Recovery Project TWRP v2.2.0)

What I did:
- I accidentally wiped all data in tablet - ROM, etc. Only left is Team Win Recovery Project (TWRP) v2.2.0 recovery console
- I put Android.zip (installation files) into Micro SD Card
- I boot into recovery (TWRP)
- TWRP does not read/detect the SD Card
- There is no files in /sdcard except one; /sdcard/TWRP/.twrps
I also
- installed adb on PC
- did 'adb devices' - no device detected when connect between tablet and PC
How?

Hello, I happy to know that I'm not the only one to have this problem.
I know it's my mistake and I'll be more carefull about doing these stuff.
I have the same problem as you, I wiped all data and only left TWRP(v2.1.5).
I tried to connect the TF300T to the laptop but I can't access to the root of the tablet (no device appeared in the window Computer).
I have all the drivers installed, also the adb, but in the "cmd" (win+R), there's no devices connected, so I can't put the original Rom to reinstall it.
So, as the TF300T has a micro sd card reader I put the zip Rom into a micro sd, but once in the recovery (TWRP) I can't access to the external sd, it doesn't appear.
Does anybody have a suggestion or have a similar problem?

First I would flash the latest twrp, (2.4.1.0) then d still a no go format sd card via fat32 (I personally like EXFAT) but only 2.4.1.0 can read that format.

After v2.4.1.0 I began to see my card where before I could not, so I guess they improved this

Same thing happening to me, I accidentally wiped system and my pad will not read the sdcard to flash a rom. Im on TWRP 2.4.1.0. Anyone have any suggestions please?
Edit: Tried a different SD Card (non SDHC) and its reading it. Lesson learned haha.

how should i update twrp , my pc do not recognize my phone anymore

How about we just tell it like it is. The people at TWRP don't care, as long as it wasn't THEIR device that this affects. Considering the last post on this was from March, I can say it seems they don't GAF. This just shows, though less visually appealing, sometime CWM surpasses TWRP without even trying.

My problem started when I upgraded my version of TWRP from 3.0.2 to version 3.1.1.0 that failed to recognize the sd card to install root and / or to store backup in sd, after much research I found no practical solution, and decided to do downgrade to version 3.0.3 of TWRP and my problem has been fixed

i have still the same issue cause it is unable to connect
because of drivers of my pc
