/data partition read only - My experience - G Tablet General

I have spent a couple of days in hell and would now like to share my experience as a big thank you to the XDA community. However, I am fairly noobish when it comes to Android so if you feel that this does not help, please feel free to delete this entry.
It all began when I restarted my G Tablet and got lots of popus about various applications, including acore, failing. I thought that this was due to me screwing up the system in some way after more or less having followed r34p3rex's superb guide here: http://forum.xda-developers.com/showthread.php?t=827209.
Ignoring this for a moment I tried to install one of the NDK sample apps on the device. This failed with the message: "read only file system". Looking in logcat it was pretty apparent that this was also causing all other applications to fail, since they were logging errors with not being able to write under /data/.
Looking at dmesg output finally confirmed this, where it reported that the /data partition had journal errors and could only be mounted as read only (this was also confirmed by issuing the mount command from within an adb shell).
This led me on a journey from just trying to remount the partition as read only (which failed with no further message), through installing clockworkmod, different versions of tnt lite, formatting and repartitioning (or so I thought), to flashing the device through its APX interface (using nvflash). None of them worked.
Not until I read a post by raydog153 - in this archived thread: http://forum.xda-developers.com/archive/index.php/t-857875.html - did I succeed by re-partitioning the sdcard (under the advanced section).
You could argue that it was stupid to not realize that a re-partitioning was required in the first place - since the ext3 partition obviously had errors and Android does not provide a fsck command (or does it?) - but I guess I thought that this was what was actually being done in other clockwork commands or at least when doing the nvflash, but obviously that was not the case.
Anyway, sorry for the lengthy entry. I just wanted to give back to the community and help others who might get the same problems I had. Also, on the positive side I have learned a lot and, like someone else wrote, I have completely lost my noob fear of bricking my G Tablet.
Keep up the good work, guys! You Rock!

almost a week without problems with FCs, thanks for this usefull info.

Trying to understand these instructions... (Android, SD Card default, EXT3, re-flash)

I have an LG Optimus T. Not the most ground breaking phone ever, but a heck of a deal for the money. Nonetheless, it's my phone, and I'm not really happy with the internal memory barrier I'm facing. For what it's worth, I have it rooted. I heard a way to partition your SD card (with part of it being allocated to ext3 file system) and re-flashing your phone somehow so the phone utilizes your ext3 partition on the SD card for housing applications. I heard several users in the IRC chat confirm this works well.
However, now that it's show time and I'm trying to do it, I'm a little confused. So please, be gentle, and I apologize if I'm re-hashing simple steps. I'm just trying to make sure I get what I'm supposed to do.
I'm working from this link here:
http://forum.xda-developers.com/showpost.php?p=10692249&postcount=1299
So from what I understand, the factory ROM can do fine, so I don't need to locate a custom ROM. That said, I just need to reset the phone to factory settings (thereby getting the factory ROM), run A2SD (is A2SD any different from A2SD Killer that they speak of in this post? I never heard of it), then go through the motions of the initial setup as it suggests (language choice, time zone, etc).
Then, prior to setting up my gmail account, I'm supposed to reboot to recovery. What does it mean reboot to recovery? Am I supposed to hold down the keys to do a factory reset? Is that what they mean by recovery?
I hate to ask these questions in a form of hand holding, but I just want to make sure I'm doing it right. After re-hashing this post several times and talking to 2 buddies about it without any further progress, I figured I'd just ask.
That said, can anyone help guide me in the proper direction? I'd greatly appreciate it.
Thanks!
make sure that you are looking at the right forum next time that link was for htc desire (use it only if it says its compatible for your phone)
before you start worrying about a2sd, you need a custom recovery, found here. once you flash recovery and boot into it, everything will be clear (ext, partition, flashing, etc)
for apps2sd, id suggest using ungazes data2sd (apps2sd and data2sd are basically the same thing, at least thats my understanding)
follow the steps there. if anythings unclear, post any questions and ill check back later
I did notice it was an HTC forum, but I was speaking with users who had other devices and claimed they used the same method, so I didn't think much of it. At that point I figured it was more of an Android thing vs an actual manufacturer thing.
When you speak of the custom recovery, what *exactly* does that entail? I was told Android phones have the hard factory reset that cannot be altered as long as you don't mess with /system under root terminal. That said, this phone is pretty much brand new. I have nothing on it that isn't already stored in the cloud somewhere (google contacts, gmail, work's email, etc).
What I'm trying to get at is, is a custom recovery needed only to get my phone back the way it was before I screwed with it? Or if I'm accepting to doing a hard factory reset, is that acceptable as well?
Thank you very much for the link. This seems a little more straight forward than the last one was. I'm also trying to understand the differences between handsets and Android versions here. For example, you mentioned the previous post was for HTC. It's a difficult thing for me to grasp because I come from a very heavy Linux background. If I mess with Ubuntu on one machine, then mess with Ubuntu on a top end server, then tinker with it on a laptop, it's still Ubuntu no matter what machine it's on. So it's hard for me to grasp the concept of Android acting differently on different machines (phones) and having different methods to different devices.
That said, it sounds like the link you posted to me is more of a generic "everything should work" type of scenario. After all, it's just moving /data. It would make sense that it would work that way, right? If not, please correct me, as I'd rather be wrong 1,000 times over again and be corrected than make 1 mistake and mislead someone or brick my phone.
Thanks for your response. Hopefully the recovery thing isn't too much of a hassle and I hope this ext thing can do the trick! What kind of difficulty is involved here? Is this fix, say, grandma approved? Or is that asking for a lot?
EDIT - Also, I noticed you spoke of Apps2SD. I have that installed... is that not acceptable to what I'm running? After all, it just seems to move what parts of the apps it can to the SD card. I was aiming to have the entire application base MOVED to the SD card. Is that what it does and I'm just a little confused??
i understand what you mean (how ubuntu on one machine is the same as ubuntu on another)
its the same thing with android EXCEPT that each android device is made different by the hardware (i.e. my phone is limited by the fact that its cpu is not powerful enough to run some apps; different components make up each device in contrast to lets say iphone, where each iphone is the same; my understanding is that each rom utilizes and has commands for each of these components so if they're different then youll need a rom unique for each device)
heres a general scope over recovery:
custom recovery - allows you to flash a rom, make/restore a nand backup, well it allows you to do a lot of things
stock recovery - only a hard reset (done automatically)
a hard reset wont cut it if you screw up your phone. youll need a custom recovery (which allows you to back up your entire system as a nand backup)
when you say apps2sd, i think you are talking about moving the app to the sd card in settings. thats not true apps2sd. true apps2sd moves the whole app to the sd card, giving you unlimited space to store apps (well actually you are only limited by your sd card)
if i missed anything, tell me. im multitasking right now (sorry)
Hahah, no you're doing quite well for multitasking! I understand what you mean, and it makes sense to me. I mean, after all, isn't it still the same analogy to Ubuntu? (at first I didn't think so, but now I think it may be more relevant) After all, if I'm running a dual proc 6 core system with 24gb of RAM, it'll certainly move Google Earth (aka, an app) faster than a Pentium 3 with 128mb of RAM would, even though they're both packin Ubuntu, Fedora, Debian, or whatever your flavor may be. So in theory, I suppose you can apply the same analogy from Ubuntu as you do Android. The catch is, Ubuntu (or any Linux distro for that matter) runs on old hardware great, so the gap between old computer vs super computer is less relevant than today's Android based smart phones, where 300mhz could mean whether or not you can run a certain app. Compared to real life, Ubuntu operates just as quick to me on my dual proc 6 core (12 core total) server with 24gb of RAM as it does my P4 1gb RAM box on my test bench.
Anyway, going back on topic a bit more... yeah I was thinking of the Apps2SD from the market. So I suppose the "real" Apps2SD is a true "mv -R" type of application (linux recursive move of data).
Okay, so get the market based App2SD out of my head. Gone. Done. Okay... the thing I'm still not understanding is the recovery. I mean, I'm looking at the hard factory reset as, say, a recovery "Ghost based" partition that some Windows computers often come with.
Example - Windows gets fubar'd. Reboot. F8. Recover system. And it dumps the recovery image on the main partition. Ta da! Just like it was when you bought it at Best Buy!
I mean, if I could get it back to factory, then I could just start over, right? Trying to put it into words as best I can... I was thinking of it like this.
Hard factory reset = Windows recovery image from Dell factory (back to day 1).
Nandroid custom reset = Own "self made" Clonezilla/Ghost image (customized with your stuff as a backup you made yourself)
That's what I was thinking. So that being said, am I absolutely positively required to do a custom backup? Can I not just rely on the hard factory reset to take me back to day 1 from when I got it from T-Mobile and (if I so desire) start the process over if I tank it? You see, I was told that it's nearly impossible for me to permanently brick an Android phone, as the hard reset, while inconvenient since it would wipe my stuff, would at least get me back to a bootable, functional ROM.
If I'm re-hashing unnecessary things and just need to focus on the fact I have no choice, by all means, e-slap me. Thanks for your help so far. I'm just trying to learn what I can! Your time is appreciated.
the thing is, a time may come when you cannot even boot your phone (lets say you were messing around and modding and all of a sudden you get stuck in a bootloop) and you try doing a factory reset but it doesnt work. this might be because something is corrupted. for android, a factory reset only wipes the data but does not restore anything. this is where custom recovery comes in handy. not only can custom recovery do a factory reset, it can restore a backup if your phone ever gets screwed up (unless you screw it up so much that you cant even access your recovery, then things get much more complicated). think of this backup as a system restore on windows (creating a restore point on windows is like creating a nand backup in custom recovery)
and dont worry about all the questions a few months back i never knew this myself so i understand
Well my friend, your patience is certainly appreciated. I understand a little better now. So let me throw out another analogy just to further solidify what little understanding I feel I have.
Factory reset = Windows restore point
Nandroid reset = Self made recovery image via Clonezilla/Ghost
Your point is a Windows restore point is only good as long as the system is solid. If your hard drive dies, suddenly your backed up restore point is useless. But... dump on that Clonezilla/Ghost image you have saved elsewhere and you're good to go.
That said, how should I get started? How do I make a Nand backup? Any guides you recommend? Will this back up my current apps, settings, etc?
Once done, how would I go about the actual Apps2SD method for making the SD card act as app storage? I assume it's that ungazes link you provided earlier?
Again, thanks for your help!
Figure this is where I should come in to help. You can install Amon_ra's recovery or clockworkmod onto your device (you can choose if there is both) but you should be able to do all that from a backup and restore menu in the custom recovery. You can go get the free version of rom manager and it should be able to install clock work recovery all without that much input from you, then you boot into recovery from rom manager. It shows you this simple yet amazing GUI that you never thought possible with something so small such as your android device. You are then given choices, do you want to flash a zip to mod your system such as custom roms, new keyboards, etc. Backup and restore (nandroid backup) or even mount it in USB mode which is useful if you never backed up, and didn't keep a copy of a custom rom on your SD card. (I never made that mistake of atleast the latter option. lol) So basically, the recovery is the "safemode" of android, only you don't get to access all of your stuff until you leave "safe mode"
and a bit of advice: NEVER flash anything without 50% or more battery.
It probably will atleast softbrick your device if it dies mid-flash.
oh, I see. Yeah I thought recovery was the actual PROCESS of pulling an old backup over, not so much operating in a sterile system environment such as safe mode.
About flashing, I would suspect it would best be done plugged in with AC power. I've had a laptop or two nearly die on me in my flashing days (went to the bathroom, came back, flashing red light, uh oh!) so I think I'll be good there.
So which applications do I need to get started? The problem I face is when I google something, there's no less than 600 ways to do all sorts of various tasks. So I have a hard time separating which one is best practice, which one is the old method, which one is definitely a bad idea, etc. So you say I can choose which ROM to use. Are they pre-built into whatever recovery software I need to use to get this job done? Or do I have to download them somewhere and put them on my SD card and then boot into recovery?
EDIT - hey how about this lil guy here?
http://code.google.com/p/android-roms/wiki/SPL
Came across it when I was googling for Nandroid Backup.
EDIT 2 - Or this guy. Looks to be the same step as the Nandroid step within the first link. Looks like the first link, while a bit more dated, is also a bit more thorough.
http://theunlockr.com/2010/02/06/how-to-backup-and-restore-your-android-phone/
Since you're rooted, you can run thiss https://market.android.com/details?id=com.koushikdutta.rommanager&hl=en and it will be able to install clocwork mod recovery. Then you just boot into it and whatever rom you want to use (found in the android development forum for your device) you install that zip from SD card and voila! You're golden with a new rom on your phone. It isn't completely needed though. lol
if i were you, i wouldnt use rom manager (it is known to cause problems). for now, use the recovery i posted in the second post. if you want to flash a rom, heres a list of most (if not all) roms for our phone.
as you start getting familiar things, you should start referring here
heres a general scope of things when it comes to flashing a custom rom:
1. boot into recovery
2. make a nand backup
3. you MUST wipe data/factory reset, cache, and dalvik cache. wiping the sd card is not necessary
4. flash the rom
5. boot normally (first boot can take awhile)
and remember, never flash more than one file without rebooting normally in between or else you might run into some problems
When you say wipe the dalvik, cache, etc, is that done during a factory wipe or do I need to do that in a separate step?
Edit- which rom would you suggest? I hear a lot about cm7. Thats the only one I recognize.
they are separate processes but they are found under the same category
so itll be like this:
wipe
wipe data/factory reset
wipe cache
wipe dalvik cache
wipe rotation settings
wipe battery stats
something like that (at least this is how it works for amonra recovery. for clockwordmod recovery, i believe they are categorized differently but its still the same idea)
Ahh, I gotcha. I remember reading instructions on clearing the dalvik-cache, so that's why I thought maybe I'd have to re-hash those links I found and do that in a separate step. But it sounds pretty streamlined!
Well, I'll give this a shot tonight. I'm still going back and forth on which ROM to use. I hear a lot about CM7, but I also heard of 1 or 2 users saying on CM7 they lost their Google Navigation or Google Latitude functionality, both things I utilize. I also had no idea the Opt T was supported on CM7. But then again, if it's anything like Linux distros, using one of the more popular ROMs has its benefits as those are normally the highest supported.
People weren't lying when they said stop googling and just go to XDA forums. Thanks for the help yet again, bro.
im using cm7 and both google navigation and latitude work for me. and i know that the link i gave you said optimus p500 roms, but all p500 roms work for the p509 (since they both use the same hardware). just remember not to flash any roms from any other forums, flash only from the p500 forum
glad i could help. if you need any more help, just refer to that forum or pm me (since i have the same phone as you)
Sweetnsour, I was just suggesting Rom manager to be able to flash clockwork, then he could flash amon_ra from inside clockwork. I think that's possible? It was more of a hint for a newer user. I remember being on the other side and since I don't personally own your device, I was just offering general android advice. Glad to see you corrected me though, anyway, good luck OP. Hope you enjoy your device modifications.
I come here with my tail between my legs ducking from any backlash I may get from any users here. I spent the better part of the evening Googling around, asking in IRC, and trying to get this part working.
I ran into several issues. Some of them are quite comical to me.
I Googled around, as well as utilized the links that were provided to me in this thread. I learned that Clockwork and Rom Manager are from the same dev team, but they are two separate products. Likewise, I was hearing other users confirm that Clockwork is the bees knees but that Rom Manager is kind of "ehh" with predictability and reliability.
After I ran into some road blocks I ended up asking in the IRC Android chat room. Some users in there directed me to some guides. I read through them. Of course, each one was different. So to a user like me, I have no idea which one is the better one to go with. The one guide kept talking about how I need to run a .sh script. So, of course, I download the files supplied and extract them. No .sh script. I ask in the IRC chat and I caught hell because I should read the directions more clearly. I read through them several times and got no where. Ultimately, some users in the IRC chat decided to link me to the guide they recommended. Later, I too ran into a road block there.
Moving along, I went into the XDA-Devs chat once I found myself at the next road block. There some users spoke to me about what I was trying to do. I linked to them the guides the Android users told me to use and they were wondering why I was using such old guides to do this simple task.
This is where my frustration is brewing. There are a million and one ways to do everything. There's no structure. No consistency at all. I've done a ton of reading and I still feel like I know next to nothing about doing a "simple" recovery. I know phones are different. I know ROMs are different. But holy hell. Doing "xyz" task on one Android phone vs the same task on another Android phone is as different from driving a lawnmower vs a dump truck.
At this point I installed Android SDK on my Ubuntu machine. However, "adb shell" was yielding a command not found error. It's nearly 2 am. I'm packing it up for tonight.
That said, let's back up a bit here. My goal is this. I have an LG Optimus T. I have it rooted. I would like to utilize Clockwork in order to do a recovery as Clockwork came heavily recommended by many sources I read about. Then, I would like to utilize the XDA site for a list of available ROMs for my phone and choose one of my liking.
Is this guide, right here what I should be using to get this job done?
Along with that, how exactly do I need to install SDK on Ubuntu so it works without headache?
Thank you to everybody who has been patient with helping me learn this stuff so far.
that guide works. after you flash the recovery from that guide, don't think that you are always stuck with it. you can always flash another recovery in recovery. as for sdk, do you need it to flash recovery? those commands to flash recovery can be done on the phone using a terminal emulator. (about installing sdk on ubuntu, I will check on that tmrw because I'm doing this on my phone, and over where I'm at I should be sleeping)
EDIT: and here's a list of roms for our phone http://forum.xda-developers.com/showthread.php?p=16535249
EDIT: for sdk, have you tried this?
http://forum.xda-developers.com/showthread.php?p=11823740#post11823740
Sent from my LG-P500 using XDA Premium App
Okay. I wasn't sure if it was safe to run those commands from the phone. I was tempted to but, ahh, figured I'd wait.
Now these instructions are exclusive to the Clockwork mod, correct? So if I get any other recovery (Amon Ra, for example) there will be specific instructions for that exact recovery too as well, right?
I'll give this a shot later and see where I end up. Thanks for your help!
Edit... It's a shame those commands aren't in an sh script already. Just a fun idea... What I'd add them to a blank text file and on the phone just chmod +x it and run it. Would that work??
the commands are fairly similar:
cwm (from your guide):
#mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system
#cat /sdcard/flash_image > /system/bin/flash_image
#chmod 755 /system/bin/flash_image
#mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /system
#flash_image recovery /sdcard/recovery.img
#reboot recovery
amonra (from here):
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system
# cat /sdcard/flash_image > /system/bin/flash_image
# chmod 755 /system/bin/flash_image
# mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak
# mount -o remount,ro -t yaffs2 /dev/block/mtdblock1 /system
# flash_image recovery /sdcard/recovery-RA-GNM-thunderg-1.1.0.img
# reboot recovery
after you flash either cwm or amonra, you wont have to do this again when you flash another recovery. to flash another recovery, you would just have to flash the recovery zip in recovery. these zips can be found here

[Q] Motorola Charm ADB Error: exec '/system/bin/sh' failed: Exec format error (8)

Hi.
First of all I have to say that I found similar threads in this forum such as this and this and this but the problem is, they either provide use SEUS as a solution (which is only for sony ericson) or Flashing the entire phone.
I have a Motorola Charm phone with Android 2.1 firmware, and like everyone else tried rooting my android (using SuperOneClick, which went well) and installing apps2sd, but failed to do so due to lack of memory, and now I've lost the shell access, Wi-Fi, Bluetooth, and what not.
The command "adb shell" gives me this error:
exec '/system/bin/sh' failed: Exec format error (8)
I can't flash the phone due to the contacts, notes, and other important info I have on the phone. If there's a way to backup these info and then flash, please let me know. If there is a solution for this without the need to flash the phone, I'll appreciate it. Any help would be appreciated!
Again thanks a lot for your help. This problem is frustrating and I need my phone back asap!
I don't want to spam but can somebody PLEASE help me out??
This problem is frustrating and I've almost lost half of my entire phone functionality, all I can do is texting and calling. It's no different from an old Nokia phone running Symbian!
I searched everywhere and I found NO acceptable solution for this problem, although it seems to be very common. SEUS only works for Sony Ericson, and I've got a Motorola...
:crying::crying::crying:
There are no other forums better than xda-developers.
Please somebody help me out!
Try to wipe data and cache from stock recovery and let us know what happen
Is there any way to backup those info before wiping the data?
I have a whole lot of notes, contacts, etc which are essential.
Please, I need an answer. I can't just wipe the data, there are info I need to keep. I have to backup the data before flashing the phone...
I've tried several tools such as Wodershare MobileGO, but none of them work because they usually need shell access, and that doesn't work.
Does anyone know about a tool that can backup the internal phone memory without using ADB?
OK I did it but it still didn't work!
I master reset the phone, which wipes all the data and resets the phone back to the factory settings, but the WiFi is still not fixed and now I can't even call since the phone requires me to login and to do that it needs an internet connection...
Nothing was fixed. I'm brain-dead.
Anyone has a solution for this??
So what state is your phone in right now?
Even without shell access, you may be able to explore the filesystem with adb, using the pull subcommand. Finding a usable version of sh (perhaps in somebody's nandroid backup), and pushing it to /system/bin/sh may help you get shell access back.

It's good that someone at least is trying to help me...
Good thing I somehow managed to get it fixed!
After talking to the customer service and hearing them telling me that "I've got no choice but to exchange my phone,"; I came up with the idea of erasing the entire internal memory of the phone. I googled, learned that such thing is called Flashing, watched the tutorial, found the right SBF, Flashed my phone, and now everything is back to normal!
Also I found out about Link2SD app, and used this one instead of the script which worked perfect, and now, although I didn't find any custom ROMs for my phone, I have the apps moved to the SD card and the phone functions properly!
However, I'm kinda disappointed with XDA-Developers, based on their reputation. I expected some help. Maybe if someone had told me what to do this would've taken much less time for me. Doesn't matter now tho...
TL;DR:
The solution was Flashing the Phone (instead of Resetting it back to Factory Settings).

[Q] Corrupt GPT, SBF and Fastboot have no effect

Dear all,
I have flashed my MZ605 (32GB) using EOS 3.0 for MZ601 with TWRP and that has worked quite well for some time, but last week I was fiddling with the navigation app and the tablet suddenly froze. The only way to get it back to life was doing a volume-up+power. Now the system still boots: i get to the lock screen, but as soon as I unlock (no password, just swiping to the right), I receive a shower of f/c messages and no icons apear. The settings screen still seems to work, but since the stream of f/c messages doesn't stop, it's very hard to do anything at all. I tried all the standard stuff first: Flashing EOS 3.0 using TWRP and Factory Reset: It seems to do nothing at all. Everything stays the same! When trying to delete cache, userdata, etc. Right after displaying the message "updating partition details", it complains that it is not able to access certain files in /data/media (a bunch of mp3 files)
Figuring that something must be wrong with the filesystem, I fired up the console of TWRP and did an e2fsck (e2fsck -vfcp) on partition 8,9 and 10, resulting simply in "unable to set superblock flags". I tried formatting the thing by hand but when doing mke2fs, it acts like it it's creating the fs (you see the numbers fly by), but when mounting the fs again, nothing changed at all!
About the partition table: Accessing the kernel messages (dmesg) with ADB says that the primary gpt table is corrupt and will try to use the backup table. It then merrily continues booting. However, when checking the partition table with gdisk (using ADB): it says nothing is present. Using the recovery options show that the primary table contains garbage and the backup partition table doesn't seem to contain anything. :S This contrasts with the fact that kernel still sees the partitions and that they are mountable both when booting normally as well as with TWRP
As a last resort I downloaded RSDLite 5.7 and the most recent SBF image. It flashes the whole thing without any errors, but when booting the system: nothing changed at all???
For the tl;dr people: Sorry! In a nutshell: fs seems to be frozen: mke2fs does nothing, fastboot flash does nothing and even sbf flash doesn't do anything at all. However the device still boots, albeit with a shower of f/c on unlock screen.
Any suggestions what to? I have been googling for many days now and reading this forum. Nothing has helped so far...
My next try would be to redefine the gpt partition table using gdisk and then hope that'll fix the frozen that. After that I would of course do a wipe all and flash a new ROM. The problem is, I can't find the standard partition layout details for the Xoom anywhere, nor do I have any other ideas what to do in case this does not work
If anyone has any hint or idea, please let me know. Thanks!
Nobody?
If anyone could please tell me their partition layout, like start - end - type for each partition. It'd really appreciate it!
Thanks!
No one?

Unfortunately I haven't been able to fix it. I still have the tablet though, hoping that one day I will come across a fix. I have two theories as to what may have caused it:
1) Physicalically the write pin of the internal flash got disconnected
2) Somehow a readonly command was send to the flash and made it read-only. I don't know if this is possible neither how to undo it.
If you have a solution, please let me know. I'm also willing to do tests and experiments to try to solve the problem.

That's too bad
Did you by any chance install a custom rom or performed any non-official other update?

Need a Microsoft Surface RT Recovery

Hi all, I have completely screwed my surface rt last night.
I was trying to do a reset and it wasn't working then I tried a bunch of other things ive read on the forum and my surface wont even boot up. its just in a constant loop ive trying to do an automatic repair and diagnosing and keeps bringing me to the boot menu.
I made a recovery usb but it doesn't seem to be working so im assuming the OS was already corrupt hence the reason the reset option in "change pc settings" wasn't working.
I would really love if someone could upload a recovery image of their surface rt. I cannot find one any where and the ones I have found they have pulled the links down.
hope someone can help me out here.
cheers.

Next time do a search. You would have found a thread on this. And, as was said in the aforementioned thread these recoveries are device specific, so even if I got mine to you, it wouldn't work for you. Take it to Microsoft and have them replace it.

i did do a search and nothing has been able to help me so far. i also did read that it is device specific but have also read it has worked for some people. unfortunatley in australia we do no have any microsoft stores so its not that easy to just take it somewhere.
I feel like there are files missing from c drive. Almost like it started to do a restore then stopped halfway. In which I have never been able to get it to that stage for that to be the case.
I did some reading and was able to find the recover partition and tried to run the install.wim file from which I understand to basically be the “OS”. When I try to run it it says “no such interface supported”
From what I understand there is just no way to do a fresh install on these things regardless of what the problem is which is disappointing on Microsoft’s behalf.

No. Those recovery images are device-type specific. Not device-specific. You can safely take one WIM file from the recovery partition of your device and use it to recover a different device of the identical model.

I see that you were able to start a restore process and it fails in the middle.
You may try the following: boot into the command line mode and format the boot partition (probably drive C: ). This would fix the disk errors if they are present, but you'll lose everything. Use diskpart tool to find the disk letter. Be careful with diskpart - do not delete partitions or issue "clean" command.
Then assign the letter to recovery partition with diskpart (say, R: ), then expand WIM file from the recovery partition with the command like this:
Code:
Dism /apply-image /imagefile:R:\RecoveryImage\install.wim /index:1 /ApplyDir:c:\
R:\RecoveryImage\install.wim - a path to install.wim on the recovery partition.
More info: http://technet.microsoft.com/en-us/library/hh824910.aspx - you need only "Dism /apply-image" part, bcdboot is unnecessary. Lets hope that "apply-image" option is present on RT.
This would forcibly expand the WIM file to your disk C:. Or at least you'll be able to see why it fails.
This may help. Or may completely brick the device and you'll need to go to service. So use it on your own risk. And you should be familiar with the command line - so don't ask how to use diskpart.
I had a problem with the recovery process when I've played with BCD and added a boot from VHD option. Had to delete that extra boot setting - and then recovery went fine. But I assume that you have not played with BCD.
Yeah, looks like people dont use search, what you want is a nice useful soul that creates a USB recovery from his EN-UK Surface_RT and puts it up on Copy, or Dropbox or something like that...

[Q] Challenging Link2SD issue

Hey guys...
I would have loved to post this to the author of this CM10.1 rom i'm running but the forum won't allow me to do that yet. It's the HTC Aria/Gratia/Liberty running user WinSuk's CM10.1 homebrew mod. S-OFF and working beautifully with a bunch of other apps for many weeks now.
I've read a couple of dozen threads with the same issue and after trying maybe 10 different suggestions that solved other peoples problems, I am forced to post another topic with this boring subject. Any suggestions would be very helpful and grateful.
The questions is about Link2SD in conjunction with this ROM. Are there any limitations on using Link2SD with this rom?
I must have read 20 forum threads and I see that there are literally thousands out there about the "Mount script cannot be created"-error.
I've tried all file systems for the second partition (FAT16/FAT32/EXT2/EXT3/EXT4) and all give this error. The only difference is that when the file system is EXT3 I get a different error. Instead of being just plain "Mount script cannot be created" I get instead "Mount script cannot be created. Mount: Invalid argument".
Either Ext3 is showing some progress or it's the only file system not supported.
The phone is obviously S-OFF so nand is unlocked. I'm very close to trying the CronMod script instead but I really would like to try Link2SD before falling back on something potentially less popular.
Thanks for reading and helping out... /s
