Gtab w/ VEGAN won't boot (help!) - G Tablet General

Hi,
My gtab has been running very well with vegan for a couple of months but two nights ago it crashed and now won't boot. I suspect that while using aldiko in bed, and resting the gtab on my body, I accidentally depressed the power button for a fairly long time and it shut down uncleanly.
When I try to boot I get the normal three splash screens (ViewSonic, g-tabdevs and >VEGAN-TAB), After the last one the screen blanks for a couple of seconds and then returns to the >VEGAN-TAB splash. Repeat ad infinitum.
Based on threads here, I tried several different things to recover but nothing has worked:
* Connected via USB MSD (via CW) to try to back-up my sdcard. Fedora sees the device and activates /dev/sdg but nothing can read it (even fdisk).
* Wipe cache and dalvik-cache.
* abd shell: /sdcard appear empty (it certainly was not before!); fdisk appears to show a valid FAT32 partition
* Ran backups with CW, which appeared to succeed, but /sdcard is still empty.
* Reformat sdcard. Unfortunately, I made an error at this point that may have doomed my recovery. I mistakenly used "Partition Internal SD Card", thinking that this was the correct thing to do. I immediately felt that something was wrong when I didn't get prompted for the size. This didn't fix it. I then tried "Partition SD Card" and got the expected prompts but this still didn't fix it.
I suspect my only recourse at this point is to re-flash but I'm hoping that some smart person here may be able to offer a better alternative.
Also, can anyone tell me what the effect of "Partition Internal SD Card" is (in terms of lost data)? What is the difference between "Internal SD Card" (/emmc?) and "SD Card" (/sdcard?)? Or is /emmc actually the external sdcard? (I was expecting /sdcard2?)
Thanks in advance for your help!

UPDATE: I just confirmed for myself that /sdcard is the external?! Does that mean that /emmc is the internal? Does the android shell re-mount these or something? I could've sworn that /sdcard was the internal. I may have lost my chance to take a backup because of this confusion. damn...

Most likely not what you want to hear but.... Start from scratch. Its probably your only hope at this point.
Good luck

Okay. Disappointing but not surprising.
Do I really have to go all the way back to stock? I was thinking that I only had to re-flash vegan...
Also, I'm still confused about what exactly happened here. Was it the power button snafu that killed the machine or was it something I did?
Also, I'd love it if someone could clear-up my confusion regarding /emmc, /sdcard, /sdcard2, "Internal SD Card", "SD Card", etc. I'm probably missing some basic info about the architecture of this thing.
Thanks!

Hey... I just tried a factory reset from CW (figured I was hosed anyway) and it worked! I'm back. Of course, all my stuff is gone but I was expecting that anyway...

Awesome you got it back up. I set my tab in my school pack and it somehow was pressing the power button down intermittently as I was walking. Found mine bootlooping and hot as hell, probably had been doing it for an hour or more. Mine would boot to cwm so i formatted internal sd and then it would only blackscreen. Glad you worked it out. Its handy to know your way arround nvflash but its a steep learning curve.

Probably you have a corrupted memory, it's alway good to try Fix Permission within the CWM recovery menu

*SOLVED* can't mount /dev/block/mmcblk0 and "Image Not Found"

I tried searching for help, but can to a dead end. After I installed JF 1.5 and the phone rebooted, it just hangs on the G1 Tmobile boot screen.... I can restart it and load into recovery but get E: cant mount dev/block/.. I also tried the DREAIMG.NBH but when ever I try to load it (Power+Camera) I get "No Image Found!"... I dont know if it cant find the recovery_testkeys or if it was screwed up during the installation process... It does boot so im guessing no brick.
Any help is GREATLY appreciated
*EDIT*: SOLVED, I downloaded the DREAIMG-29.img, renamed the file with a .nbh extension, and bought a SD READER to MAC 4gig San Disk Card. IT ENDED UP BEING THE NEW CARD and READER THAT MADE IT POSSIBLE!
http://koushikdutta.blurryfox.com/G1/DREAIMG-RC29.zip (Rename DREAIMG.NBH..
Hope this helps this pesky problem
maybe
It might be that it's not reading the sdcard right to read image to reflash. But also some people have been saying some apps are causing it not to go past the g1 screen seem the most common factor is desktop theme apps are doing this people have been able to remove these apps useing umbuntu to remove these apps and all goes back to normal.
Hmm.. umbuntu has never been a real good friend to me.. but yea the SD card was my last possible indication. I thought that after doing a factor reset under recovery deleted the apps...? Is there a way to just reflash to stock rc 33 or rcc 29? Im sort of new to the Android Dev scene... Could the Recover_Testkeys.img image be causing an issue also?
Thanks
Edit: Iv heard that the type of SD card might be an issue (Transend, San Disc, ect.)? ..... I dont know though.
deleted comment... accidental duplicate post
Try a wipe. I had the same thing happen to me only i did something dumb, but once i flashed it, it worked again.
It happened to me today, It stayed on the Android screen for about 30 minutes So I removed the battery and turned it on with home+power button,
did a wipe, and applied the update again.
I dunno if doing the wipe helped but it works now
By wipe you mean recovery then (Alt+W).. Iv done it about 10 times. I keep getting the "cant mount SDCARD" and "dev/block/mmcblk0" after attempting to install update.zip.
Any other thoughts..? thanx
please tell me you have adb set up. if so i can try to help you otherwise i can't do much for you
Tubaking182, To be honest, i dont know for sure if I did set up adb... Could you please explain what it is and if it is still possible to set it up? If you could help me, It would be GREATLY appreciated... im about to give up.... such a pain in the a**
Bump.. for help issues
they may have changed the vold.conf in order to support A2SD, but that would prevent the phone from recognizing SD cards that are not partitioned.
I was rooting my HTC Magic 32A and had the same problem when I choose [Flash zip from sdcard] at RA-hero-v1.6.2
The message was "cant mount /dev/block/mmcblk0"
Then I choose [Other > Move recovery.log to SD] at RA-hero-v1.6.2
And went back to choose [Flash zip from sdgard] and then it works.

[Q] Can't Anyone Help ???

I'll try this forum, over 200 views on my other posts and no suggestions. Is the problem that obscure ? The tablet, while not worthless, is getting there as I am unable to load any of the hacks and fixes to the SD card to install. Is there a work-around the SD card so I could reinstall the g-sensor fix ?
With all the great minds on this forum, surely someone will have some insight into my problem. To start with I am running the latest Vegan release (thanks Team) and have been since 1/1. The only thing I can think of that might have caused this problem was that I foolishly removed my SD card without dismounting it and popped in a blank one to see if it was working. Since then, I am unable to mount an SD card. If just says "Unmount in Progress". When I click on unmount, it will unmount it and give me the "Mount SD card" option, when I try to mount it, it will say "preparing SD card", then go back to "Unmount in Progress". When I try to mount a new card, it says "Card blank or unsupported file system". But all the other card I have used in my Gtab give me the same Unmount in Progress issues. I reinstalled Vegan. Apps that used to work, no longer work, they just open and close (No FC message)
Someone please help !!!

I'm not one of the g tablet great minds but I'll make a suggestion that always works for me.
1) Format your external SD card in a computer with Fat32. Preferably not a quick format.
2) Using Recovery wipe EVERYTHING, repartition/format the internal memory.
3) Reboot into Recovery
4) Connect to a computer, mount usb, copy your files over again.
5) Re-install the rom of your choice.
In my experience (at least on the HD2 with Android) crazy FC's and otherwise unexpected behavior from a freshly installed ROM means there are leftovers that were not removed from the previously installed rom.
IMHO the device should be completely empty of every bit of software before reinstalling.
Edit: On a side note, I have NOT been able to get an external SD card from recovery which is why I do everything through USB-Mount with the computer.
If you can mount via usb, you could put the ClockWorkMod (CWM) update.zip and recovery file and then reboot with Pwr/Vol+. That should install CWM.
Then you will be able to boot into CWM and repartition or whatever you need to do. Personally I would repatition, clean out the caches, wipe data, etc. and then start with a clean slate.
Hope I have not misunderstood what you need. Hope this helps.

Factory Re-set
Don't know if this will help or not, somtimes you need to clear out the cashe.
Have you tried going into settings and clicking factory reset?
You will lose your user data, but this might be enough to fix the problem. I think you have parts of two installs overlapping each other.
Also, reformatting the SD card sounds like the next step to try if factory reset does not fix the problem.
Third you could NVflash back to stock and then start over. Then do factory reset after each install.
If you have to wipe everything I would suggest formatting your internal sdcard in clockwork to 2048 and 0

If you did a factory reset and nothing happened then the reset didn't work. I would install clockwork recovery from here.
http://forum.xda-developers.com/showthread.php?t=851657
Then boot into clockwork recovery and clear data/cache. You will have to redo the market fix and install your apps. If this doesn't stop the force closes then boot into clockwork recovery and repartition your sdcard to 2048 and 0
I'm having the same problem. I did nvflash and started fresh. Installed CWM making sure to wipe data/cache. I partioned the SD to 2048/0. I installed vegan 5.1 and its update. I think I did everything by the book, yet it still says Unmount in progress. This did not occur when I was running stock.
I tried the sd card from mt Evo as well. It does the same thing. It also does not recorgnize any USB flash installed as well.
I've run out of ideas. Can anyone help?
Thanks very much.

My VEGAn 5.1.1 says same thing but I never have a problem accessing files on it (/mnt/sdcard2). Are you sure you are not confused by the fact that the internal memory is divided into 2 GB "system" and 14 GB SD1?

Be patient, it took forever to mount a thumb drive for the first time and I too had thought something was wrong. Try again after a reboot and a couple of minutes.
Hope this helps
Thanks for trying to help. I pretty much gave up and installed TNT 5.0. I've had the thumb drive in there for 5 minutes but I'll keep it in to see if it shows up. In TNT, the SD card seems to be working/appearing fine.
I really liked Vegan, but I'll keep TNT for at least a few days to see how it does.
Thanks again!

[Q] tablet erases any new file on reboot??

Hey everyone,
So I got my tablet today and have been working on it for the past 8 hours!! I finally got CWmod on it and running. Had a nightmare of a time getting it to work correctly and after using NVFLASH to nuke the whole tablet and install the stock ROM, then updating i was able to get CWmod to run. Now I'm having a really odd issue.
I can boot into CWmod. I repartitioned the SD card, mounted it. I can see the device in windows but when I add ANYTHING to the internal SD card it is completely gone once I reboot the device. I'm trying to get a ROM on it but it's like the drive is locked or something really weird. It copys onto the tablet just fine. the second I reboot everything is deleted.
I feel like I'm missing something here. I had that issue with it when I ran the stock ROM. I could change something and it would not stick after a reboot. For example registering my device on kindle and then downloading books. as soon as I reboot the machine it's as if i never registered it. I'm really at a loss as to what to do with this. I can't seem to get it to save anything on the internal storage.
Well after fiddling with it for a while longer I'm about to give up. I used NVFLASH to get it to the stock ROM again. updated to 3588 and yet again, I can't get any changes to stick. I can change anything and everything on it while it's powered on. The second I power it off and reboot it nukes everything I did (and takes close to 5-6 minutes to boot). I even mounted it and deleted every single file on the internal storage. They all came back upon reboot. I reformatted the entire SDCARD, I reformatted all the user data, did a cache wipe.. nothing works. I'm wondering if my unit is defective? at this point I would love to just have a tablet that I can actually use. I can't understand how it's even possible to not be able to make any changes on the device unless it's reinstalling the ROM everytime I reboot?
What version of CWM are you using and how did you install it?
I was running CWM 8. I couldn't install it via the internal storage. It would boot into recovery mode and "install" but once the machine rebooted it would not boot into CWM. I tried it several times same deal. I could install it but once it rebooted, nothing :/..
So I had to use the micro SD card to install it. I edited the recovery command file and pointed it to the SDCARD2. It installed finally, and stuck!
I tried using the microSD card to install the other ROMs. But unfortunately it will not mount in CWM.
I'm trying to get CWM back on it after doing yet another wipe with NVFLASH. We'll see if I can get it to work..
So i'm basically sitting here with a brick.. unless I never power it off lol!
Ok well another odd thing is going on with this. I'm up and running with CWM 08 again. I can turn on USB mass storage mount. The tablet shows up in windows and on my linux box. I can make whatever changes I want, adding files, deleting everything on it. Nothing matters cause once I unmount and remount the device it's all back to normal. It seems like nothing is allowed to write to the internal storage even though it thinks it does write to it??

[Q] SD card 0.00 bytes free, device offline ?

I'm having problems guys
I don't know if I succesfully rooted my phone as when I ran ./root.sh through the linux debian terminal, I received multiple errors saying deivce offline
This also happened when I did Linux/adb reboot "Device offline"
I am now having the problem that my internal sdcard appears to be unusable as my phone keeps saying that is full though it must have over half of the 13gb free
I can access it through mass storage but I can't download/install anything as I apparently have no space
I have not had this problem before, if anyone can help I'd appreciate it.
adb can be weird. it doesn't get covered much on xda but you have to make a file called 70android.rules or something to that effect, I can give better details some other time, right now I can't remember the location or exactly what goes in it besides the samsung vendor id but it basically allows adb to see the phone.
if you have that setup then maybe there is another problem. not sure what issue you have with the sdcard but does it work from the phone and not through a data cable? vise versa? not working at all?
When I go through Settings-SD Card storage my SD card (internal) says that it is full though it's not!
Perhaps I don't understand what the "wipe data/factory reset" does on your phone through red recovery
p.s. If gou actually are running 3e would it say 3e recovery?
I can't install appa as my sd card is entirely full
I had unlocked my phone before through the same comp, I don't know why I am having problems.
Every time I root this phone I do something different everytime (I forget what I did last time)
Others have suggested doing an odin? This phone is a refurb it has many errors aside from freezing then vibrating- force closs
It is slow, sometimes when it freezes the icons (four main on home that you can't movebon stock rom) rotate an entire 90 degrees it's weird as hell
I wish I never sent my Infuse in b/c of the cracked screen I should have just gotten the screen fixed
Thanks for your response
try a factory rest through settings>privacy, then if that doesn't help do an Odin flash back to stock with repartition.
it seems rare on American devices but a lot of galaxy s devices have had trouble with the internal SD card going corrupt. in some cases its fixable but I'm not really sure if that's what's going on here.
Ok so I did reset through settings-privacy that did the trick
Now to start all over again...
I seem to be having a hard time finding the backed up files on Titanium...
oh [email protected] my bad....
I forgot to mention that the privacy reset formats the sdcard. part of why its often successful is that it'll fix certain issues with the SD card and it wipes app data saved to /sdcard/data/
titanium backup keeps the backups on the sdcard...

by the way, I think this reset option also erase everything on your external_SD as well. I found that out the hard way very early on.

Accidentally clicked 'FACTORY RESET' in HBOOT

I accidentally hit the FACTORY RESET option in HBOOT, and it seems the phone just rebooted into TWRP without doing anything. However it seems my SDcard is now empty and unformatted. Earlier I had two "Internal SDcard" options in TWRP\Mount but now I just have one, and if I try to click on Mount USB storage, the removable disk appears as an unformatted disk on my PC. Is there any to fix this? Is the SD gone for good or can I recover the data?
Run a Ruu and your phone should be fine again (dont forget to relock your bootloader)
I think your data you wiped is hopelessy gone..
Sent from my HTC One S using xda premium
I made a nandroid luckily, but I just realised that the problem is due to the sdcard not actually being able to mount. It says
E:unable to mount '/sdcard'
I'm using TWRP 2.5, maybe I will try with 2.3.1.0.
EDIT: Okay that didn't help. If I run a RUU won't it erase my SD card? I don't want to lose what's on there, is there any way to fix it and be able to mount it again?
Bottom line: I need the data on my SD... is there any way to recover it?

reformat the sd card and use recovery tools (google for them). most of your stuff will be easily brought back from the dead.

before going through the trouble of an RUU, if you can see the unformatted disk from your computer just try formatting it there into a FAT32 partition like you would any other drive. This has worked for folks successfully. But as for data recovery....
Dang that sucks... was there some sort of confirmation before starting the wipe? I've always been paranoid that I might fat finger it randomly and it just wipes without some kind of second check
Reflash the recovery img from fastboot then boot into recovery, you should be able to mount sd
Zero help to anyone, but I did exactly the same thing myself and had to mount the SD card in recovery and format.
It hurts!!
Well it's official. All my data is forever gone. And no there was no notification, I hit "FACTORY RESET", and it just paused for a second then rebooted into TWRP with my SD instantly destroyed. I tried every possible trick in the book. The problem for me wasn't just getting it to mount and work again, I could have done that in 20 seconds. The problem was to try and get it back WITH all my data, which I failed.
In the end, I made a RAW disk image backup of the sd card partition which for some bizarre reason ended up with a file that was 6 MB in size instead of 10 GB... I knew my data had somehow got nuked. I decided to just reformat it (Quick Format) as FAT32 on the PC, then I ran a host of data recovery programs, even those that were specialised in finding stuff from formatted drives. None of them could even find ONE file. But after format I was able to use it as normal.
I have really no clue how the entire drive was nuked within a fraction of a second, even all the data on it, but it is what it is.
On the bright side, for some reason my phone seems MUCH faster now, especially when installing apps, and the battery seems to last noticeably longer too.

You should automatically upload your photos or files somewhere. Mine upload to Dropbox so if anything bad happens, nothing too bad can go wrong.

It's hard to do recover because normal format recovery might not work but you can try the old ver of Easy Recovery Pro 6.x(I don't know why but the lastest ver seems removed RAW recovery) and use the RAW recovery, it usually could find some stuffs. You can also try out Diskgenius.
