[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.

[Q] Cannot flash CM on 3100

Hi everyone,
I have a Galaxy Tab 2 7.0 (P3100) and I have rooted it and installed CWM so I could install the latest CM release. But when I try to install the CM zip file, it says "some symlinks failed". Now my tablet won't boot, the splash screen with "Samsung Galaxy Tab 2" keeps on forever. But I still have access to CWM and the Download mode so I think everything's not lost yet
Here are the exact steps I did:
- Uploaded the CM image (cm-10-20121213-NIGHTLY-p3100.zip), the gapps zip and the root zip to the tablet.
- Installed heimdall on my computer, with the correct drivers.
- Flashed CWM on the tablet.
- Installed the root zip on the tablet using CWM.
- Booted the tablet again just to make sure rooting was enabled (yes, it was).
- Opened CWM again, wiped data, wiped cache.
- Installed CM image:
--- Error: some symlinks failed (status 7)
- Installed the gapps zip file (worked)
- Formatted /system
- Installed CM image:
--- Same error: some symlinks failed (status 7)
I wanted to try another CM images, maybe that one is broken, I don't know, but now I cannot upload more files to the tabled internal SD card. I can't mount it anymore on my computer because the tablet won't boot. I tried using an external SD card (from another Android phone I have) but CWM says "Cannot mount /external_sd" when I try to mount it.
Can anyone help me? I want to flash the latest CM on my tablet.
Thanks!

This seems to me like either a broken recovery or maybe a corrupt download. What version of CM are you trying to flash? Also, what version of CWM are you using and where did you find it?
Posted from my Fascinate using XDA Premium

Yeah, I also think the download was corrupt. I tried flashing cm-10-20121213-NIGHTLY-p3100.zip (the latest one on the day I flashed) and my CWM version is 6.0.1.1. I downloaded it from ClockworkMod official website, they say that is the latest version for my tablet model.
I believe CWM is working and that the image is corrupt, but I can't find a way to flash another CM image because I don't know how to put another file inside the tablet, or how to flash an image from my computer to the tablet. Can I use something like heimdall to flash a CM to my tablet? Can I upload an image to the tablet so I can use CWM to install it? "adb push" doesn't work, it doesn't detect my device in CWM mode. Do I need some working/stock Android image on the tablet so I can flash CM over? Or it will work no matter what's installed (given that the download is not corrupt)?
Thanks!

Please tell me you made a backup after rooting and before modding?
If you didn't (which it sounds like), BAD CRISTIAN!!! But this will make you learn to do it from now on, huh?
Which leaves you only two options, both include using a computer to get a ROM zip to the tab...
1- connect tab to computer in recovery with usb cable and download a new copy to SD card via computer.
2 - remove SD card from tab, place in computer card reader, and download a new copy to SD card via computer.

How exactly do I download a new copy of the image to the SD card? When I plug the tablet to the computer, I can't access its files. It used to show me the files when the Android system booted, but on Recovery mode it won't display them, the filesystem isn't mounted. Should I do anything special? Should I use another CWM version?

I tried that, but it seems I cannot mount the external SD card using CWM. When I hit "Mount external SD Card", it says "Cannot mount /external_sd". The SD card works fine though, I use it on another phone and on my computer... Is this a CWM problem? =/

Pull the ext sd card out of the tab and put it into a card reader on a computer using the adapter the micro sd card [should have] come with.
I tried that, but it seems I cannot mount the external SD card using CWM. When I hit "Mount external SD Card", it says "Cannot mount /external_sd". The SD card works fine though, I use it on another phone and on my computer... Is this a CWM problem? =/

Possibly... However if you can mount your internal sd card, you should be able to place the zip on there. I don't usually suggest using internal, but if that's what you gotta do....

I found out why I couldn't mount my external SD card with CWM: I had to format it with FAT32! I don't know what filesystem there was before, the SD card I have was used by an old Éclair phone. I still couldn't install others CM 10 images (I really don't know why), but I managed to install CM 9 and the brand new CM 10.1.
Thanks, guys! =)

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.

"So I put my phone into airplane mode and threw it... worst transformer ever. -.-" -My friend

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
there is a small not working sign on driver
i have updated that but not worked

Stuck with ICS in CWM and no USB.

Upon trying to update my TF101 device to Jelly Bean using this guide (wiki.cyanogenmod.org/index.php?title=Install_CM_for_tf101), at the 6th step of Installing CyanogenMod from recovery (i.e., Select install zip from sdcard) the tab says it's unable to mount the SD card.
The exact error is: E: unable to mount /sdcard/
I have CWM v6.0.1.3 installed.
Now, I'm stuck with a TF101 that isn't detectable via USB (or APX for that matter) running ClockWorkMod without root. What do I do? I'd like to upgrade to JellyBean but if that's an issue, I do not mind sticking with ICS.
Bear in mind that I'm completely new at this and I might need a step-by-step guide.
P.S. - I can't post links. Sorry.

If you boot to ICS and enable USB Debugging in Settings - Developer Options, is your device visible from the PC?
If yes, then I would try using PERI to root and install CWM.
If not, then I would try installing the Hybrid Touch 6.0.1.2 of this recovery: http://forum.xda-developers.com/showthread.php?t=1855686 Download the file in ICS, place it in the /sdcard/, flash from Recovery and see if it will let you. If you can see your microSD from recovery put it there. Then reboot and you should have a working recovery.
I have seen quite a few people try to use that wiki 6.0.1.3 and have no luck with mounting the /sdcard/

No such luck. Still not able to mount the /sdcard/ and it doesn't seem to recognise the microSD as far as I can see.

Might be a bad USB cable. I have seen a few users (myself included) where my cable would charge, and be recognized by the PC but it would not do APX or ADB. New cable fixed it for me, and most others.

It was working till right after I fell into this rut.

I used mine for ADB, 3 days later I tried it again and no dice. Thought it was the ROM I was on, tried another one, still no dice. Flashed back to stock rooted, still nothing.
New cable, viola!

You should mount the sd card using recovery and then use your PC to copy the zips you need back to your sd card and then flash them. Some recoveries will automatically mount the sd card as soon as you connect the phone and the PC with the usb cable. In others you may have to go into the mounts (or Mounts and Storage) menu and select mount USB storage or sd card.

Try to push rom file through adb side load..
I happened to me once..
Try this..
http://forum.xda-developers.com/showthread.php?t=2575150

Plug her into computer
Make sure drivers are working for adb by mounting storage than running the command "adb devices" assuming you have set up your sdk. if your device shows up. Run this
"adb push ROM.zip*/data/media" in the prompt.
If your device is not recognized.
Update drivers manually using the device manager on your computer. You will need to install the drivers. That's easy. Just look up how to. That should fix it with minimal confusion
