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!

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.

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.
hello, i was about to flash a new rom on my hd 2 and i forgot that i put a wrong sd, and i partioned my sd and now i lost everything, is there a way to recover all my files? i havent done anything to the sd since i partioned it!
edit: i did this in CWM recovery
Try google this testdisk-6.12-WIP. It can restore partition along with files in it. Or try some data recovery software,mostly they works

do you know any program that can recover all kind of files, because i need all my files
anyone? please?
Not gunna happen what do u think happens when you delete things from your trashcan

i did the partion on the phone, i heared thats it possible to recover them if i havent written any new files
Try a program like Recurva I'm not sure if it works on flash memory though.

That is only applicable for magnetic disks. And also not if you deleted the whole damned partition, created it, and reformatted it again.
That alone is worse than writing a lot of files.
Consider your files lost. Next time back them up to somewhere.
i partioned it by cwm, and thought i had the wrong sd in.
Hi Malbadawi,
I would like to suggest you that go for Stellar Data Recovery Services & Software.
For my personal experience, when I had to recover files from hard disks or flash memory (usb key/SD), my best choice is GetDataBack (you will need FAT edition, not NTFS).
Just insert your sd in a card reader and follow the step by step tutorial. Do not attempt to reformat your card if your PC doesn't see that, the app will look into it at a lower level...
btw, a 100% recovery isn't always guaranteed, as you know, [email protected]!# happens
Yes, GetDataBack is a great program, try it instead of Stellar Data Recovery. But reformat card as said. Works fine for me.
Thanks all for replies i will try them when i get back home
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:

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?

Hi Mike have you tried formatting the SD Card to exFat or Fat32, also check that the sd card is clean along with the slot in the phone.
Best of luck
I was trying to boot into recovery, and from Bootloader, I scrolled down to far and hit Factory Reset.... immediately, I held the power button down to try to avert this.... and it stopped (I think). I then booted into recovery (TWRP 2.6.3) and then used file manager to look at sd card... and its empty (aside from one TWRP directory.
First I didn't think a "Factory Reset" formatted the SD card... but if that is what happened, is there any way to recover this information... isn't this formatted in ext4 with journaling??? I know I have recovered things from linux when I have deleted them...
But, if I am out of luck... is there a solution to this problem as my phone is not really booting either (I suspect it is looking for files on the SD card which are no longer there)...
Any help would be appreciated.
THanks!!!!!!!
syntropic
HTC One-s (S4).
Hboot 2.15....
Rooted/S=off/SuperCID
OK.... I managed to boot into my ROM....
It seems to indicate that my SD card is not mounted..... I realize I can go to recovery and wipe/format my sdcard. However, just for kicks.... I would like to run fsck on it.
So.... I am in terminal emulator... (I have bash and busybox installed too btw). I found fsck. But when I type "mount" I cannot see my sdcard....which makes sense because it is not mounted. But I don't know the dev/block for it... and I can't find the list with all the partitions that people have already determined.
Can someone let me know the dev/block so I can run fsck? Or let me know where that document is when all the partitions???
THanks again!!!
