[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?

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? =/
Thanks!

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! =)

[Q] TWRP , can't find SD in install

I had issues with the last CWM release so I decided to try TWRP. I use Rom toolbox Pro to get into recovery and wiped all to flash a new rom. Problem arose when I went into" Install" program of TWRP, I could not find my SD files. I change from root to SD card and only saw twrp, cwm and upper level. I tried many ways , but could not get to the files in my SD card. Any help would be appreciated...

Check in /data/media
If your stuff isn't there its gone. If you don't have any ROM zips and you have already wiped system you will need to setup and use ADB to push one.

Have you tried formatting your SD Card with an external card reader, then loading the files?

I tried an earlier version of TWRP and my SD card popped up fine in the Install section. Maybe it's me.... but I dunno the latest versions of recoveries CWM and Twrp have had bad sections....

[Q] TF300T, TWRP and ROM issues

Hola banditos, I am new here, and not really that big into android, so forgive me if I do not refer to something correctly. I am currently having multiple problems with my Asus Transformer pad. A few months ago I purchased said product and rooted it. I had a few minor issues but eventually got it working. Flash forward to yesterday night at around 10 PM, and I had wiped the system and removed the Operating system. "No problem" I thought "I can just download the Jellybean firmware from the asus website" ( I had done this before.)
I downloaded the firmware, put it on my SD card and flashed it. The only problem was that I had flashed the Japanese version of the firmware onto it.
At this point, TWRP apparently thought it would be hilarious to stop working. Upon downloading the US version of the software and loading it onto my SD card, TWRP was no longer able to mount the SD card. That my friends is the major problem.
I have checked on my computer, and the SD card is still functioning. I have went into the Japanese OS on the Android and it is still accessible and functioning. I have downloaded multiple versions of TWRP, different recovery kernels and tried multiple solutions through other threads. I have tried reformatting my SD card to EXFAT, Fat32, NTFS and regular FAT. I have tried putting the firmware on the internal SD card and loading it from there. It recognizes that the firmware is there, but fails to install it. ADB also fails to recognize the device (I have everything set up correctly on the PC but it still fails). Fastboot is working fine though.
I have crawled through web page to web page looking for a fix. About 7 hours in total, and I am yet to find one that works.
Help me out here.
My gear:
64 GB sandisk SD card
Asus tf300t running a japanese Jellybean 4.2.1
TWRP 2.6
You're my last hope

There is another way! Inside the us software zip there is another zip inside that zip is a .blob file extract it to the directory where adb and fastboot are on your pc open up command prompt and cd to your fastboot directory: now type: fastboot flash system blob
This will take some time!
Then flash twrp and open it then wipe data system cache dalvik cache and then flash the firmware via twrp reboot!
Sent from my sensational HTC Desire C

I have grabbed the blob file from the US firmware. Upon using the "fastboot flash system blob" command, I get the message < waiting for device > I have waited a half hour, and it is still there. am I doing something wrong?
Edit-
I have since got the fastboot to work after some research. When I went to wipe the data system cache and dalvik cache, TWRP said that it had failed. TWRP still failed to recognize my SD card
Edit Edit-
Again after more searching, I have found a TWRP version that has recognized my SD card. However, One problem still remains before I am finished. I am still unable to flash the stock firmware. I navigate to my External SD card in TWRP, select the firmware zip file. Almost instantly it says that the install failed. Any ideas?

[Completed] [Q] How To Fix vold.fstab in Maxx GenxDroid7

I have Samsung Maxx GenxDroid7, which has very low internal memory (<200 MB). I have an external micro SD card of 16 GB, but still couldn't install many apps due to insufficient internal memory.
I read on the Internet that if I modify vold.fstab and replace the word "sdcard" with "sdcard2" then my external SD card will act as internal memory.
So I rooted my phone and installed Superuser, but I haven't installed ClockworkMod recovery or any other custom ROM yet.
Problem Description:
I installed ES File explorer on my SD card and allowed root access to it via Superuser. I then went to /system/etc/ from ES file explorer, edited vold.fstab and replaced the word sdcard with sdcard2.
When I restarted my phone the external SD was no longer accessible. ES File Explorer is also gone, so I cannot undo the change that i did. I tried installing ES again from my data connection, but the installation fails (and the phone reboots immediately). I am not able to install any new apps.
I am unable to access my external SD card, so I can't put anything there via PC or via recovery. I tried pressing the power button +Volume down to go into system recovery mode. I see only these options
reboot system now
apply sdcard:update.zip
wipe data/factory reset
wipe cache partition
When I try to select the second option, it says "installation aborted" as the SD card is not accessible. I tried to select the 3rd and 4th options, but that didn't help either - I think factory reset will not reset vold.fstab.
I only have the default apps and Superuser now. I somehow need to find a way to get write permission to /system/etc or to /system/etc/vold.fstab.
Can someone let me know how I can edit this file again? I don't have an original vold.fstab

Hi
Thanks for writing to us at XDA Assist. Have you tried formatting the sd card back to its original state?

Not Work

I think the best idea is to ask the person that wrote the guide you followed in the first place how to reverse what you did.

[Completed] Wiped all system data, now stuck on cwm custom recovery mode

I am a complete newbie to rooting. I followed the kingoroot guidelines and rooted my Idea Aurus 3 phone. Root was success. The next step I did was downloading custom recovery and cyanogenmod ROM from here to my memory card
I flashed the custom recovery with flashify. The next step I did was wiping all data from the device by entering in to recovery mode (including cache and everything)
I was hoping I could simply install zip from sd card. But when i click on this option, I cannot find my sd card nor zip file (I checked most folders including emmc, etc, sd-ext and couldn't find SD card. The custom recovery name is Phylz touch 6
Now basically I have a phone without OS and all I can do is accessing custom recovery. I don't have a back up too
I can also see an error log "Cannot mount custom path"
I formatted the memory card to exFAT from exFAT 32 hoping that would work, it didn't help as well.
Also tried to connect phone to pc using USB (thinking I can move rom to system memory), but wouldn't detect phone memory
Now, is there any way to get this fixed? Any help would be awesome
Thanks!!!
