How to replace one file when failing to boot

Hey guys
I screwed up my vold.fstab trying to get "_ExternalSD" back.
Unfortunately! I did not run a nandroid before I made the change.
Now, I can dirty flash my rom on top, or go back to a nandroid from a few days ago, but I'd really just like to recover and go on my merry way. And maybe learn something in the process.
Only thing is, I can't figure out how to access the phone other than the External SD card through CWM.
Can I mount the internal /system and access through USB? Is there some facility to copy a file from one point to another? Any other methods? I guess the phone has to be up to run ADB, right?
I don't know how to generate a flashable zip but I could extract the original version of the file from the original rom. I assume that its non trivial to create a flashable zip, but maybe someone can comment? It looks like there is signing and certificates involved..
thanks for any ideas

this is why i hate it when people make those guides.
messing with the vold.fstab is dangerous (even though its only a few lines) if your trying to recover your data, give up. its not going to happen. (sorry)
when you edit the vold.fstab it messed up the partitions on your internal SD card and most likely did the equivalent of wiped your /system partition. (or another important one.) your actually lucky it did not completely brick your phone.
your post was a little vague, but if you can, just restore an older nandroid, or wipe everything and install another ROM. (you can try dirty flashing but i dont think itll work)
if you cannot access CWM, then follow the steps in This guide. it should get you back up on your feet. after you follow that guide flash a gingerbread ROM (any gingerbread rom will do fine) then you can reboot and flash any ROM you want. (it needs this to fix a quirk in that script)
Hope you get it fixed
EDIT: re read your post, if your feeling adventurous and want to give it a shot, boot into CWM and connect it via usb. you can now get into an ADB shell on your phone by typing 'adb shell' if you have adb all setup and working. (im working from memory here so dont quote me on any of this)
now, you should be able to access your /system folder from that shell. be very careful though, i dont have much experience right here, and if i remember correctly you might not be in the full root directory yet)
if you can get into it try replacing your vold.fstab with a stock one,
if you dont have a stock one lying around, make a nandroid of the current state of the rom, then flash another rom, pull the vold.fstab, then re-restore back to the broken one and restore it (id upload mine but my phone is OOC right now )
after that just reboot and hope it resolves itself, if not then just follow my advice above
and keep that guide i linked to handy, messing around in CWM has the ability to brick your phone, if it does, then just follow that guide.

re read your post and updated my last post right after you posted
after dealing with noobies all day, i forget sometimes people want to try big things

Thanks guys. The info I was missing was there's no special trick to attaching adb while in CWM! Just plug in!
My phone is back up and running and partitions are fine as far as I can see after just booting up.

Hi there! I messed up with the vold.fstab filfe on my tablet – I replaced it with a downloaded file with the intention to transfer apps to my external SD card.
Now my tablet is only showing the startup logo and won’t continue loading. I can access recovery mode. Now I want to restore the original vold.fstab file.
My questions:
1. Using the Android SDK, the file explorer does not show any files, though my tablet is recognized.
2. Using adb push, it yields an error: permission denied, how to successfully push the original vold.fstab and replace the existing vold.fstab?
3. If I dump an image of my tablet and edit the dumped image, would this be easier compared to the steps above?
Thanks!

Try this.
If this doesn't help you should ask in the section for your tablet to get more specific advice.

You need to do an adb remount before you can push. Was it rooted before?

Mansa_noob, yes, my tablet is rooted. I followed some instructions about adb but had an error saying access denied, and also no files are displayed at file explorer. See my posts above. I also mounted it successfully. I will post some sreenshots later.
Please if you have some instructions, I am willing to try.

Hi twitchyEye, it did not work. It attemps to install (using the install update from ext sd card) but then says installation aborted.
Any more suggestions? Thanks

What recovery are you using? I suck with adb so I got nothing on that front.

It was the stock recovery from my Tablet. I don't have it on hand right now, I will post later. The chipset is RK3066. My problem is my tablet has no official support on the internet (maybe becaue it's still new). Model is Skyworth S71(3G).

I see. Yeah this is over my head man. I thought for sure you were running a custom recovery and it was an easy answer. I'm actually struggling right now with adb myself with a similar issue something about permissions whenever I try to do anything to my phone. So I guess right now would be a perfect time for somebody to chime in with a smarter answer!

This is strange. A properly rooted phone would adb remount to r/w system. Something is fishy. Is it rooted+

I am sure it is rooted, because I downloaded an application from Google play to check it it is rooted or not. It is really rooted. I alvo confirmed this as I can now fully backup and restore my apps using Titanium backup before the tablet is messed up.

OK. Odd or not, it is what it is. Is it possible for you to load a custom recovery?

I want to try, but the stock recovery is my last hold as I have no stock ROM. If I overwrite the stock ROM, I cannot reinstall it as I don't have a copy of it.

So why not flash cwm with nvflash and then make a backup of your current stock rom? I did exactly that.

[Q] Flashing a ROM without being able to boot phone.

So,
I'm a dumbass and accidentally flashed an "update package" rather than a full ROM. I can not get past the "HTC ONE" white screen now..I have full access to recovery and bootloader, but can't boot the phone to mount as "Disk Drive" so I have no way to put the .zip file I need on the SD Card. Is there a way to put the correct .zip...even a stock ROM onto the SD Card without the phone being able to boot? I looked around and couldn't find anything.
Thank you so much.
-Brian

Boot the phone into recovery, go to mounts and storage, mount system. In adb push the file to /sdcard/

Hi, I'm working on exactly the same thing. I am only about 20 hours in and have learned quite a bit, but not having an SD card you can slip into a PC card slot is a major challenge. I have managed to get recovery back on the phone, and am successfully connected via fastboot. I can't figure out the ADB shell...I've installed SDK manager and have tried to enter the ADB shell, but cannot. Keep getting error messages. WHen I attempt to flash a rom via fastboot, the process starts, but then quits with the error that my media does not include android-info.txt or android-product.txt. I have tried every tmo ROM available, and the Nandroid back up. It is a paper weight? Thanks to anyone who can shed some light!

That's not how to flash roms, perhaps that's why. If you don't understand adb you really should not be rooting or unlocking anything until you have a better understanding of the tools you have available. Otherwise you end up in here asking if your phone is bricked when really you just have no idea what you're doing in the first place. Flash recovery in fastboot, then flash the rom from recovery.

Yea I figured it out..I had a recovery working though.
With regards to rsvjoon,
As stoneyjonez said...you need to flash a recovery (Say CWM Touch) using fastboot...something along the lines of "fastboot flash recovery recoveryimagefilehere.img" and then reboot into recovery...etc etc.
I followed this this step-by-step process exactly and got it to work, I recommend the same.
Cheers

hello...i as well need a step by step about pushing the rom to /sdcard/ in adb....if you could pm me that i would be thankful!

Thanks...and you're right. But I have successfully flashed CWM recovery...I just can't get anything on the phone to flash. Fastboot starts the process but ultimately I get an error with each rom I try that it can't continue because I'm issing those two text files. So anyway, your point is well taken. In the past, once I had recovery, I'd just slip the micro SD card into my computer and pop a rom on it. totally different deal without that capability.

Thanks brwetz. That is exactly the process I followed when I originally rooted my phone...and everything was swell. I fongooled things when I flashed a custom rom (which also worked just fine) and then decided to restore my Nandroid. for whatever reason, that process left me in recovery with nothing on the SD card to flash back.
Thanks again for the response.

What *I did* to put a .zip file on my phone without being able to boot it up was this:
-Go into Recovery -> Mounts and Storage.
-Plug your phone into your computer using USB cable
-Make sure it says "Unmount /sdcard/" and "Unmount /system/". If they do not say that, just press them (they are toggles)
-Make sure the ROM.zip file is in the same directory as your AndroidSDK/adb (for example, mine is C:\AndroidASK\)
-Go into command prompt and type "cd c:\whereveryouradbislocated"
-Once you are in your AndroidSDK (adb) directory, type "adb push romname.zip /sdcard/romname.zip
-Unplug phone from computer, close command prompt
-Go back in Recovery to main menu and do a factory reset/wipe cache partition/wipe dalvik cache (I can explain those more if needbe)
-Again go back to Recovery Main Menu -> Install Zip from SD Card -> Choose file from SD Card -> Select the romname.zip file you just pushed from your computer and install that .zip
-Reboot phone, be patient as it will take a minute to completely boot up.

Need help - stupid mistake

Well to make it short and simple. I did a factory reset on my tablet and i had seanz rom running. Now all it did was just get stuck at the nexus loading screen. I went into cwm and wiped everything out. So now it gets stuck at the asus boot screen. I don't have a backup in my tablets internal storage. So im trying to use my sd card. But I can't figure out how to get CWM to read my sdcard. Is there anyway i can fix this problem?

1. Wrong forum. This should be in the Q&A section.
2. CWM (and TWRP for that matter) does not support the external SD card. You will have to ADB push the ROM you want to flash to your internal storage. There are lots of threads in the TF300 section about doing so, filled with instructions and troubleshooting tips.

Hey heres a tutoral I wrote for flashing back to stock or if stuck between roms

currently adb pushing file to sd card. Ill post back with an update
UPDATE: so I did an adb push of the rom file, but when i go to search for the file, CWM tells me: couldn't open directory, no files found

if all fails then try using adb in linux, most likely a ubuntu live cd(which is free).

[RESOLVED] Flashing Custom Rom Results In Noob Hiccup, No Backup and Can't SD Mount

Hey guys, unfortunately my first post here will be under messy circumstances but I've managed to mess my phone up pretty bad.
I have an AT&T HTC One X. I'm running on Windows 7 64bit, all drivers updated, permissions set, etc. etc.
I was supposed to be flashing Cyanogenmod 10 when I ran into an error in that was in the actual zip file. Prior to installing TWRP I had Clockwork mod installed. I flashed TWRP onto my phone & have been using that since.
My noob hiccup was instead of deleting just the zip file I managed to wipe the entire sd card, backups included (I'm an idiot, I know).
Now I don't have an os and cannot run in debugging mode in order to get adb to function properly. When I adb I cannot access /system/ nor /sdcard/. I can only access /data/ & of course installing CM10 through that directory has resulted in more fails.
Please tell me there's a way to salvage this. Thanks in advance...

Stick to ROMs in this specific (AT&T One X) forum, and you won't go wrong again (at least not in that way).

[SOLVED] CWM + Cyanogenmod 10 installation help - Did I forgot anything ?

Hey XDA ! =D
I'm still interested in installing Cyanogenmod 10 on my LG Optimus One P500h, but I want to make sure I follow the steps properly first - this is my first time installing a custom ROM, and when I heard it was possible to install Android 4.0 on the P500h, I performed a backup from ROM Manager, and I "bricked" my device a few days ago. XD
I wouldn't want this to happen again, but at least, I must say I have more experience now, and learned a lesson.
Did many searches on how to install CWM with Cyanogenmod 10, I found many different ways to do it, and I'm still unsure of which procedure follow.
Read the FAQ and that was really helpful.
I will list the procedure that I would normally try - please correct me if I forget anything:
0. Root the device
Done that already. I'm on Android 2.3. When I flashed the KDZ on my LG (and so to my surprise, got me updated from 2.2 to 2.3.3) , I've used V20A_00.KDZ, so I *assume* this is the second baseband.
1. Compact/Trim Cyanogenmod ROM
Downloaded CM10 here. This look correct: http://forum.xda-developers.com/showthread.php?t=1811325
January 8: Build 7/Final
I chose C10 over C11 because more things are compatible I believe - was it Bluetooth that did not worked under C11, but does on C10 ?
Anyways, that solve a known problem: many users said they loose network after the ROM installation. Shinobisoft confirmed it was because of the lack of space on the System partition, right ? Compacting the ROM would also fix problems for installing Link2SD ?
I've downloaded the tool "OOne ROM Editor" and opened it - it doesn't look complicated at all. What apps are safe to delete ? Will converting them to "user app" save space for system apps (I'm not sure - Where are the apps stored when defined as "User"? SD card rather than /System ?) ? Can I delete fonts without problems (I don't see why I can't keep ONLY 3-4 fonts, not 10) ? Then how much space will be left on the device ?
Read I cannot delete LatinIME.apk. Is this the default keyboard? 20MB is huge, there's no way to compact this file, right ?
Assuming there's like 10MB free, network will work, but I will have no choice but to use Link2SD to install apps fully on SD card, is this correct ?
2. Baseband stuff
Ehm, what are we referring to as "baseband" in first place?
All ROMs starting with CM7 are new baseband. If your device had Android 2.2 prior to flashing, you are on old-baseband. There is a patch for that also in the LG Optimus One FAQ on the first page, not sure which post off the top of my head tho. If your device had Android 2.3 on it then you have a new baseband device which shouldn't require any patches.

Allright, this should make this a lot easier - as I said, I originally was on Android 2.2, when I bricked the phone, I flashed "V20A_00" throught KDZ Updated, then I rebooted as 2.3.3, so I shouldn't do anything, right ?
In "About Phone", it's listed "Software Version: LG-P500h-v20a".
3. Install ClockworkMod Recovery
This look like the tricky part.
A lot of people on other sites said to use ROM Manager...

First, serious word of advice. Stay away from ROM Manager. It does not handle this device correctly.

ROM Manager's way of flashing recovery is broken by design. Do NOT use it unless you are comfortable with rescuing your phone via ADB/fastboot like many people before.
Click to expand...
Click to collapse
Yes, ROM Manager is completely broken in this regard. It needs to download a signed ZIP and discard it and report an error when verification fails. Heck, ZIP format has even its own CRC check. What ROM Manager is doing (download whatever .IMG and flash it no matter what) is a nice WTF! Broken by design, go rewrite from scratch!

I don't trust the use of ROM Manager anymore on my device, and I'm not comfortable with using it again. I actually wonder: When I press VolumeUp-Home-Power, the phone perform a factory reset (Many people asked already why. This apparently mean that CWM is not installed).
But is it really installed? ROM Manager actually says: "Actual Recovery: ClockworkMod Recover 5.0.2.0". What? Am I supposed to press VolumeUp-Home-Power to verify, only to do another factory reset?
So what would the non-ROM-Manager method be ? I found this one here:
http://forum.xda-developers.com/showthread.php?t=1146566
I know about the Android Terminal Emulator already, and as a Linux user on PC, the commands "su", "cat", "chmod", "mount" are not unknow to me. I should be able to do this... That's not risky ?
So when CWM will be installed, I should be able to boot in it using "VolumeUp-Home-Power"; in theory, this is a bootloader, so if the ROM get screwed up, I *should* be able to access the bootloader to restore the ROM (I compare this to a PC BIOS - the OS is screwed, but BIOS remain accesible) ?
How could I explain that when I bricked my device with ROM Manager, I couldn't perform a factory reset, and only had access to Emergency Mode (I assume there is not such thing as a "Recovery Mode" on a P500h stock, new/untouched. The equivalent immediatly perform a factory reset) ?
All Android devices have a recovery partition. This is essentially a section of the device’s memory devoted to a very basic recovery system that is separate from the normal operating system. This is normally used by manufacturers for recovering a broken device (as even if the operating system crashes, the recovery image has a chance of still being access and used to reflash the operating system, etc.).

By default, the LG P500h recovery partition perform an immediate factory reset - CWM will be installed here, so I should be able to access it if the ROM freak out. But why couldn't I access the factory reset, when I bricked the device? That's what I wonder.
4. Access CWM and do a Nandroid Backup to SD Card
I will now have the files boot, cache, data, recovery and system, as well as"nandroid.md5" on SD card.
5. Wipe everything, clean SD Card
Perform "Wipe data/factory reset". This will format the /data, /cache, /sdext, and .android_secure
Select the "Advanced" option and on the next screen select "Wipe Dalvik Cache". Confirm the wipe.
Not necessary but I do it anyway, in the "Advanced" screen select "Wipe battery stats" and the confirm that wipe
For a clean installation I recommend formatting the system partition too. From CWM home screen select "mounts and storage". On the next screen select "format /system" and then confirm the format.
Press the back button until you are back in the CWM home screen. Select "Install zip from sdcard" and then select "Choose zip from sdcard". Browse your sdcard for the ROM to install and select it. Confirm the installation. Now wait for the install to finish.
Go back to CWM's home screen. Select "reboot system now" option and let the device boot. The initial boot will take a couple of minutes. Don't panic.

6. Partition SD card (?)
Is this at that point that I should do it, in CWM ? Or wait until I access Cyanogenmod and use a software on PC to partition ?
Assuming I don't partition, I guess I definitely will lack space for applications (Due to the space of Android 4.0) ?
I will do "Partition SD Card>EXT4 1024MB>Swap:64MB. Is this correct?
7. Install Cyanogenmod
Install ZIP from SD Card, choose the CM ZIP;
8. Install Google Apps
Once the install is done, I won't reboot and immediately install Google Apps, with "Install ZIP from SD card". I chose this package (Working on JellyBean):
http://forum.xda-developers.com/showthread.php?t=1917411
Then I should reboot in CyanogenMod and finally install Link2SD, I believe.
***
..Did I forgot anything ?
I *believe* that makes sense, but this is my first time installing a ROM - I doesn't look *that* hard, I did researches, but things can go wrong... :/
What should I do if I screw things up? Use KDZ Updater again ?
I'm still a little worried about that baseband thing, and the lost network connection.
Thanks for the input, cheers!

1) Use FlashImageGUI app to flash recovery/or use Recovery.IMG flasher by @shinobisoft
2) Forget the baseband stuff
3) Factory reset is the default action when you boot into stock recovery
4) If you partition SD card your data will be wiped anyway

1) I've checked FlashImage GUI, it look really simple to use. This is what I see now:
https://dl.dropboxusercontent.com/u/67605655/snap20140216_103936.png
For flashing a recovery image, should I select Clear Dalvik & Clear Cache ? Do I have to enable USB Debugging?
Where can I find the recovery image for CWM ? Here maybe: http://forum.xda-developers.com/showthread.php?t=1523050
I don't know, I would download CWM v5.0.2.7_Touch_p500-Build 4.zip.
Would the terminal emulator method would be easier (I still need to find recovery.img)?
Code:
$ su
# mount -o remount rw /system
# cat /sdcard/flash_image > /system/xbin/flash_image
# chmod 755 /system/xbin/flash_image
# flash_image recovery /sdcard/recovery.img
# mount -o remount ro /system
# reboot recovery
Since I have no Nandroid backup (I cannot do it until CWM is installed), what could I do if something goes wrong ?
2-3) Excellent, thank you.
4) I plan on partitionning, but at which point shoud I preferably do it?
Thank you, I appreciate the help - sorry for all the newbie questions.

1) Recovery image is in the zip fie itself. Extract it
The terminal method you're telling is just what FlashImage GUI does (notice the word 'GUI' )
2) Partition it whenever you want. Just backup your stuff before doing it.
3) As much I hate to say, the thanks button is there for a reason

Ok, so I've downloaded ClockworkMod_5.0.2.0_Recovery_ThunderG_Official here: http://forum.xda-developers.com/showthread.php?t=1523050
Extracted the ZIP and put the file recovery.img at the root of the SD Card (USB storage); so now all I have to do would be to start FlashImage GUI, select "Recovery Image", browse and choose the file recovery.img, then flash (I won't select Clear Dalvik & Clear Cache unless I have to (It's not selected by default, so I assume it's not require - although I've backed up my stuff already).
It's that simple?
I'm still in a learning stage, I bricked the device once with ROM Manager, so if that work, I should be more confident for the rest (I will take a Nandroid backup). Thanks for all the great explanations - Will press the thanks button soon
(How much thanks can I give per thread?)

Don't worry you won't brick it.
(Talking from my experience of completely hard bricking aka dead booting my device due to kdz)
Just flash it.

Allright, I got it!
I saw the success message, then used the keys to reboot in recovery, that worked!
At the boot, I can read "ClockworkMod Recovery v5.0.2.0 E: Bad boot message "recovery ".
I believe the "E: Bad boot message "recovery " is a known issue, and but is not a problem - please let me know if I have to do anything about this.
So now I will compact the Cyanogenmod ROM (I don't know how much space I should free, but I'll try to free a decent ammount), and perform a Nandroid backup to SD card.
I believe the hardest/scariest is done. From now, if the ROM install fail, I could just restore the backup, I guess.
Are they any case when CWM is unaccessible (When I bricked my device, I had no access to stock recovery (which only perform factory reset) but just Emergency Mode. Why was that?) ?
Thank you, I will let you know about the rest.
(Will press the thanks button at the end I don't know if it's OK to thanks on multiple posts on one thread, on this forum)
EDIT:
That error message means you dont have SD-ext. Ignore it.

EDIT 2: Nandroid backup succesfully taken! I now have the files .android_secure.vfat.tar, boot.img, cache.yaffs2.img, data.yaffs2.img, nandroid.md5, recovery.img and system.yaffs2.img. Will backup these on my PC.

It's OK to thanks on multiple post.You just have a limit of 8 thanks per day.
ROM manager made anything inaccessible except emergency mode or fast boot mode for some people.
(When I flashed my Oone with CWM, ROM manager worked like a charm)
You can flash the ROM now

I appreciate the information;
It's quite akwards that ROM Manager broke everything (And I asked for a BACKUP - that's so broken, it brick the device when you want to BACKUP <__<) - when it rebooted, it was in Fastboot mode, and I never saw that mode before. Tried a few recommended commands without problems, but when I rebooted, I only had access to Emergency Mode.
What would be informative for me to know, is that ROM Manager seems to not only have screwed the ROM, but the stock bootloader as well. Weird.
Shinobisoft said we need to compact the CM10 ROM with his utility first, because the System partition is too small (Otherwise, I will have no network). I will do that, I have the tool, that doesn't look complicated.
From now, I am backing up my SD Card content (DATA is backed up too) with Nandroid present on SD, so I could start formatting, immediately followed by SD partitioning.
I guess I should be fine at that point - if anything goes wrong, I should have the option to restore the Nandroid backup.
Will let you know when I'll have the ROM compacted (Probably today).
EDIT: YAY !
Everything worked as we expected! I saved my SD Card on my computer, wiped it, partition it from CWM (EXT: 1024MB, SWAP: 64MB. I have a 16 Micro SD, class 4 (Can't afford higher class much, for now), then installed the compacted ROM. Immediately after, I installed Gapps, then rebooted.
That worked !! This ROM is DOPE ! Totally worth upgrading ! Blazing fast !! (Will be slower with apps installed, but well)
I also have a working network!
There is one thing that "failed", I cannot get Link2SD to work. It always says "cannot create mount script". I checked with Windows (I know by experience that I should absolutely not edit Unix partitions in Windows, I just check), and the FAT32 partition is the first, then I have a EXT4 partition, then the Linux-Swap, I don't know why it doesn't work.
I used Gparted to format the EXT4 partition to EXT2, but same problem, "cannot create mount script". What am I supposed to do ?
Thanks youuu !! =D
I'm really happy to have done this on my own, with help - I now have more experience with Android, I have experience with Windows, Linux OS and OS X, but never did I tried flashing a ROM yet.

Hi,
Tanks for replying. out of 200mb, I have 70Mb free, but on /data. Last time i checked, /system was almost full (where can i check system size?).
Seems like lot of people have this link2sd issue.

@GameX2 use root explorer, it will tell you the remaining system space

That's what I've thought, according to "Storage Analyzer", /sysem has as minimum free space of 84KB (!) and a maximum of 4.63 MB.
Did not experience any weird stuff, for now.
sd-ext folder doest exist at root, but it's empty.

Link2SD needs at least a MB to create mount scripts.
Delete some system apps like TerminalEmulator, CM File manager, Email, Exchange services.
Also use mini LatinIME.

Yes, that's right. You can check /system space by using Root Explorer. Or go to
Settings>About phone>Partition info.
I got 10+MB space left on /system partiton after trimmed the ROM and installed mini gapps.
You're right, Link2SD only works if there is 3MB, at least, left in system partition.

Once you have success with link2sd creating mount scripts, you can access at /data/sdext. Been a long time since I ran Jan 8 cm-10, but I seem to recall that partition info is not in settings/about phone. But link2sd will have it. Or there are other apps. When viewing storage info from settings menu, don't confuse internal memory with /system (190mb). Internal that is shown there is/data (200mb).

Install some file manager from play store. In phone settings (not file manager) choose security. Then choose to allow installation from unknown sources. Then open your file manager, scroll to sdcard/downloads/ ,and click on flashimage GUI.apk. Installation process will start.
