[Q] Error when wiping data and cash - G Tablet General

Was having random reboots so decided to restore a backup from early in the week.
When I wiped data and cash before restoring I got a strange message I have never seen before.
E: can't mount /dev/block/mmcblk0p2
Said the same thing when I tried to wipe again.
Just wondering if this is a problem or if its normal and somehow never saw it before.

It's referencing partition 2 on that mmc device. Why it can't mount it and what it's trying to do by mounting it though are beyond me. Maybe manually unmount/remount it in CWM and see if it works?

Repartition the SD card.

I was planning on formatting the internal memory at some point. Really should have just formated from the start but I was stoked about my first rom flash on Gtab so o put it off. My main question is: does this have something to do with the security risk that was exposed recently? If so I will take all measuress necessary to fix my tab...

Nope. Not at all. Some G-Tablets are affected by a problem that corrupts the data partition, and repartitioning fixes that.

cwm cant mount /system and /data

Hey guys I need your help
I've been using cm7 for a couple of weeks now. I havnt had problems until today.
I flashed build 32 over and for some reason it wasn't booting up. It was on the splash screen for a while (it usually does that and when I take battery out and restart it boots) so then I took the battery out. Next thing I know is that my phone is stuck on the mytouch screen... I went to recovery and when it booted into cwm 3. I got a error saying it couldn't open system/recovery/log or something like that... it still went to cwm and I checked the mounts and it said /system and /data wasn't mounted. I clicked it to mount and it gave me an error saying it couldn't ... therefore it wouldn't let me install cm7 or do a wipe... is there anything I can do to fix this? It seems to be that the nand. Is corrupted or something...
I think, based on your description, that pulling the battery at the particular instant caused the secondary problem.
A "factory reset" reformats /data and /cache. But not /system. You can do that manually from the mounts and storage menu, then either restore a nandroid backup or install cm7 and gapps.

Hmm I font think its just two directories... I think my whole internal storage is messed up. I tried using the reformat option from cwm but no luck
Time to discover what you might be able to accomplish with Fastboot and a USB cable.

I think a lot of people are having problems with clockwork 3 in the nexus forums, and more specifically with it screwing up partitions. I was luck just to lose my ext position on my sd...
Reformat and reflash seems to be the easiest fix...

i dont know how to repartition the phone storage :/
i tried doing it off cwm and it wouldn't let me... is there anyway to do this through adb? i think adb is working...
Reformat the whole card, and then try to repartition. This will write your data, so back up first...

how do i do that? o_o through cwm? i tried formating everything including system data cache... and i dont know how to repartition through cwm. cwm is the only thing i can get to right now :/
Sorry, looks like the only option in clockwork is to partition. Can you not do it from your pc?

guys... ((((( am i totally effed up? i couldn't find anything i could do.. no matter what i did, the /system and /data would NOT mount... so i cant format it
I have never tried this, but you might consider it.
In this thread is a method to return your phone to stock -- it uses the bootloader's ability to repartition and reformat everything somewhat automatically, using a file called PD15IMG.ZIP from the SD card's root folder.
http://forum.xda-developers.com/showthread.php?p=11011692&highlight=pd15img.zip#post11011692
There's a link in the thread to the .zip file -- look to post signatures. Put the file on an SD card (with another phone, or camera, or Micro-SD to SD adapter, etc.) and boot into the bootloader with that file on the SD card.
I do not know if you can rename the .zip it to update.zip and force it to flash with Fastboot's update command, because the PD15IMG.ZIP is a specific thing this phone's bootloader looks for. As stated, I have never tried this, and do not recommend this. It might work, or, it might cause more damage. Putting the file on an SD card without Fastboot will be safer.
You could try to boot your phone into fastboot,
and then type
fastboot erase -w system
Your phone wont boot after that, but you should be able to flash a new rom from clockwork.
ive tried both the pd15img.zip method. it says "partition update fail"
and i also tried the "fastboot erase system -w" and it did not work.. it says that it can't be done. i also tried to format /system through adb and cwm, and both says it can't because it must be mounted before
From your description, it seems to me that the internal flash memory has a damaged partition table -- easy enough to repair if this were a hard drive you could remove and take to a linux system somewhere. But it's a phone, and a bit of flash memory that can't be removed.
Flashboot has an "erase <partition>" command. I don't know what it does, since it's not well documented. Does it reformat an existing partition? Or does it remove the partition from the partition table? There is no commensurate "create <partition>" command, so perhaps it recreates an empty partition. But I tend to doubt it.
I would think such work might be done from an engineering bootloader or engineering recovery system -- one available to HTC service technicians, for example.
Since you're not getting a great deal of help in the MT4G subforum, you might post your question in the top level Questions and Answers forum.
Sorry I'm not much help with this.
One last thought. The bootloader itself has a Factory Reset. That might do it. Might not. But like chicken soup, it probably couldn't hurt. Boot into the bootloader (volume down while powering up), select BOOTLOADER with the volume control and then the power button, then select FACTORY RESET. Perhaps it will do something positive.
eh.. i couldnt do anything. i tried all options. its like impossible to reformat or repartition the drive..
i actually called up insurance and they'll be sending me a new mytouch 4g..
we have just told them that it doesnt go past the mytouch screen.. would they figure out that it is rooted? i mean.. choosing recovery from the bootloader menu takes it right into cwm lol
Just flash the stock recovery back via fastboot...

you are sending the fastboot commands while in the bootloader right? I would imagine you are but I just want to make sure.

[Q] Superwipe/flashing ROM error (Sensation XE) (Answered)

Hi guys,
OK so I have had my first Android phone for 2 days now (Sensation XE) and I have rooted it last night with Revolutionary.
Had some hitches, but got there in the end.
Anyway so to play it safe I thought I would flash Android Revolution 3.6.8 for sensation
I have clockwork and made a full backup, which is now on my computer.
Anyway I copied over superwipe and the ROM to the SD card and booted into recovery.
I attempt to use Superwipe, this does start but then fails on its own package, Status error 1 Installation aborted
When I try to flash the ROM on its own (Wiped using clockwork) basically the same thing happens again
What could the the issue?
Redownload zip files.

Even if its happening on both?
I would give it a try.

Nope still the same issue
Also, I formatted my SD card and redownloaded again, it still states "E:error in /sdcard/android revolution etcetcetc
(Status 1)
Installation aborted
If you do the wipe manualy via CWM (wipe cache,boot,system,data...) does it work?

Good news! Seems as though I have fixed the issues.
Basically formatting (Even doing a full long format) of my Sd card wouldnt work, but would always show 1.6GB total space, the Card is 2GB, so I would expect around 1.8GB at least.
Anyway Superwipe wouldnt work, but the one from this thread: http://forum.xda-developers.com/showthread.php?t=1280358
Is different, and did actually run.
Since it has run, its seems as though its deleted a hidden partition, I now have 1.8GB of free space on the SD. and I can now instlal anything without fault.
Hope someone else who is having the same issues as me see this thread, it would stop them from pulling there hair out!

Thank you so much. I was having the same issue, and this one works!!!
I was having the same issue and this worked for me.
Thank you!
Glad I'm helping people!
Can you press the "Thanks" button for me?
I had the same issue on my phone, and it turned out that Android Revolution and the Super Wipe that comes with it do not work with ClockworkMod. They are instead built to work with 4EXT. If you try to install with ClockworkMod, it will get a failure in the package. The reason for the failure is because the cache is still mounted, and it tries to wipe it. You can work around this by going back and unmounting cache, then trying to run the Super Wipe install again. You'll have to repeat the same procedure for installing Android Revolution.
One thing though is if you do install Android Revolution with ClockworkMod instead of 4EXT, you'll miss some important prompts. Once you get your phone up and running again, install 4EXT, then reinstall Android Revolution with it.

SD Card Error Message

Code:
[B]E:unknown volume for path [/sd-ext] [/B]
This is the error I get using Revolutionary and am flashing a new rom using the 'correct' method spoken of here.
This error message occurs after I've wiped Dalvic Cache. The phone still performs as normal without any issues. But I'd like to get rid of this error if i can.
Can anyone help with this or has anyone had or seen it before?

Try re-formatting the sd-ext partition using 4EXT recovery. Failing that, backup your entire SD card contents and re-format the whole thing, then copy your files back. I had a 512MB EXT3 partition on my card for ages from my old Desire days and A2SD+ ROMs. Never got your message but that's what I would try.
Isn't that SD partition? I also have that (when flashing, or doing backup) and I thought it was normal coz I don't have partition of my SD.

Thanks for your answers guys.
@wnp_79 I always format my sd card when i flash a new rom.
@MarlIX I'll try formatting again and making a partition using the whole sd card size to see if it solves it.
I guess that it depends on situation in which you're extending main partition with SD card (as HTC Desire users have to do in order to install ROM which doesn't fit on internal memory). In normal cases you'll have such warning because you don't have extended partition on SD (But someone please correct me if I'm wrong)
ah ok so i shouldnt worry about it then really unless the rom i want to flash requires extended partition?
I can make a partition on Revolutionary i get these options 128m,256m,512m etc etc and then i brings up a menu saying swap size 0m,32m,64m,128m or 256m.
Any guesses on the best way to set my card up?
If you are not using it then use either choose the smallest size, our use 4ext recovery to remove it.
Whenever i did it, a 0MB swap was just fine.

I see an option to remove all partitions and start from scratch so next time i flash i'll select that and maybe that will sort it out.

try the second method
Ok i can't get either method to work. I've tried editing it myself and I used your zip.
Whats strange is, I scrubbed everything with the g2x scrubber AND i wiped everything manually. I still get this stupid issue with the SD card and also, a Background from my previous rom loads up all of a sudden????
I know a lot of people got this working and all but damn, this has to be the worst rom I've ever dealt with in terms of getting this to work.
I was working on this last night, DO NOT MESS WITH THIS STUFF IF YOU DON'T KNOW WHAT YOUR DOING!!!! I wiped the internal partitions and it took me a good 4 hours to get my baby back!
It's gonna have to wait till a ROM dev adds the function back into cm 9. I was trying to change all of the necessary files myself, i figured that the file system was close enough to Linux for new to figure it out, like spare parts did in cm7.
but it ended up in a real nasty soft brick.
Seriously, messing with your vold.fstab can f up your recovery partition and make it so you can't get into recovery, and you can't reflash it because the partition tables aren't there.

[Q] SCH-R530U Complete make-over NEED GENIUS**!!!!

I have a SCH-R530U US Cellular GS3 running on JB 4.2.2 with AOKP's mr1 build 5.
Kernel: 3.0.67-aokp-00038-g5a02406
I'm bored of this ROM and want to try Liquid Smooth for the features and hopeful battery life extension. I have been trying to get my phone back to stock EVERYTHING every couple weeks for the last few months now, and have not found any stock rom/kernel files that do anything other then brick my device into a hard boot loop. I have a NANDROID backup, so all is not lost, but I'm just so sick of not being able to find ONE file that will give me stock kernel and stock ROM so I can try a new ROM with new features and speed. I would flash LS over the AOKP build, I just haven't found any info on whether or not the ROM is compatible with my kernel, or if that's even an factor and Iv freaked out too many times over thinking my phone was F$*!ed to be that ballsy in trying something without having exact instructions or some sort of literature/video. So Id rather be safe then sorry and start completely fresh.
Also to get rid of all the non-sense i have on my phone from flashing tons of files to get rid of AOKP, and not knowing how to delete them.
The other issue. My SD card isn't recognized by anything. I cant move apps to my SD card with any app out there, the file is emulated and what i think happened was somehow, I ended up with two SD card files, and they have mixed files in them. So being as newb as I am, idk what files i need to keep in order for proper functioning of my phone and which I can delete, so i can move apps to the SD card and pictures and all that stuff to free up space on my phone. Im more then willing to delete everything on the card, but that wont fix my unorganized internal file clusterf$!*#.
Iv seriously being looking for months, downloaded ADB toolkit to try and get stock back that way, but just another boot loop.
TL;DR
1. Need stock ROM/kernel files for my version that will actually work and not bootloop me.
2. Can any ROM be flashed over any kernel, or are there restrictions with specific ones?
3. How can I fix my SD card problem (not recognizable by any App2SD app; literally none -says my SD card is emulated), with messed up internal files?
PLEASE HELP!!!!
Through your recovery do a full wipe (system, data, cache, dalvik) Sounds like you want to wipe your internsl sd too? Depending on where you keep your info you can wipe your internal SD but it's not necessary.
When you flash a ROM it will come with it's own kernel so you don't have to worry if a ROM is compatible with your kernel. Just make sure you flash a ROM that is compatible with US Cellular.

Thank you for your reply, honestly.
I vaguely remember doing a full wipe (system, cache, delvik, and data) and it not fixing the issue. But, I will try again. I'm more concerned about my SD card issue and all the messed up files. Will wiping all this fix that? Using ES explorer, I have about six /0 files... Idk if you know much about that, but from what I've learned, within that ONE /0 file, there should be storage for my SD card (data/media) and of course, there's nothing there. So, do you think or do you know that doing a full system wipe will remedy the problems? No tone intended, not trying to be a jerk, simple curious for the future.
Just format the SD card. Wipe everything off if your comfortable with losing the info. You can save important stuff top your CPU if necessary.
