My buddy is having a hard time flashing a new ROM on his tablet. Currently he's running Cyanogen with TWRP.
Apparently TWRP formatted his tablet randomly and he hasn't been able to install a new ROM because his tablet won't mount the system or cache. It keeps failing. Neither system or cache are selectable to mount and it says "E: unable to mount '/system' "
And ADB isn't pushing anything.
Any thoughts why?

TWRP formatted his tablet randomly??? Never heard of such a thing!
And we need more information:
What versions of bootloader, CM, TWRP and you are trying to push what in ADB?
Do you have access to fastboot? What rom are you trying to flash?
What did he do - as best as he can remember?

It wiped his data when he went to decrypt data and it asked for a password. He hit cancel and it said system memory 0gb
He has the newest twrp, he was on 10.2 trying to go to 11, and he was trying to push the mounting through adb and was getting errors. Because he is unable to select them In twrp
He has fastboot but it doesn't respond to commands at all.
Thank you for any help

Sounds like a soft brick.. Due to a wrong recovery flash or he flashed the newest version of twrp, and did a full data wipe.. It has known issues!!!!!
Becareful from here.. Like berndblb said we need verify we still have fastboot access!!:fingers-crossed:
What is the OS of the PC your using to fastboot from??
Well I tried installing cromi for him and it stalls at 87%

UPDATE: We restarted the tablet, mid installation because it froze, and it booted up to his old 10.2 just fine. I recommended he do a clean format now but he doesn't want to do anything lol.
So right now I'm just thanking God he didn't brick it hard

Did he have the tablet encrypted or did the request for a decryption password just show up unexpectedly? If it's the latter - I have read about this a number of times - unfortunately still cannot make rhyme or reason out of it, but I suspect it's a corrupted recovery....

Which probably means he doesn't have the correct fastboot drivers installed. That would No. 1: Get fastboot working. Download the Google Universal Naked drivers, install them and try
Code:
fastboot devices
If that returns the tablet's serial number, you're in business. You could then flash CWM 6.0.4.6 in fastboot. I would probably wipe data (hope he has everything backed up) and flash the rom.

@lj50036 could you elaborate on the issues of TWRP 2.6.3.2.? sbdags included it it in his bootloader/TWRP flash package for CROMi-X and one guy just softbricked flashing CROMi_X after flashing that package, he seems to have done everything else correctly and I suspect the recovery is buggy???

My issues are first hand.. It flashes just fine, everything seems to function correctly.. It's only the wiping of data that has a issue.... It just hangs says its doing it thing but nothing ever happens..After a hard reboot TWRP now asking for password will not mount any storage of any kind... The fastest way to a soft brick.... I posted on the TWRP forum, about the issue... Maybe we need a new forum letting people know about the issue, so we dont end up with a riot!!!

It was version 2.6.3.0.
He had no decrypted files he was just seeing what it did when he hit decrypt data. I asked for a password which he obviously never set and hit cancel. And it said he had nothing in internal storage.
However, after the install froze on an older Cromi version I put on his sd card (from my 700t), we held down the power button and rebooted. It booted up fine to his previous Cyanogen 10.2. WITH all of his internal storage still there, EVEN THOUGH, he did a format from TWRP already.
So it's definitely a problem with TWRP. His tablet is back to the way it was before the fiasco and he is afraid to do anything else.

Are you sure about this???
Because TWRP 2.6.3.0 was too big for the recovery partition of the TF700 and never properly installed????
For any reliable advice you need to provide the bootloader version (which you still haven't given us) and if you have a working system, you should be able to boot into recovery and give us it's version number.
For installing CM 11 on the TF700 you need to be on the 10.6.1.14.10 bootloader and have the CWM 6.0.4.6 recovery.
TWRP 2.6.3.2 supposedly works with CM 11, but I would not trust it - read about too many problems with it....
And anyway - in terms of performance, neither CM 10.2 or CM 11 beats CROMi-X on this tablet - period.

Hey guys, this is Wade, the cause of the whole fiasco.
It was the newest TWRP 2.3.6.2, but I imagine it might've been a problem with the bootloader? I had no idea that the bootloader needed updating; I thought that once you could boot what you wanted, that was it, but obviously I'm mistaken. Where do I find the bootloader version? It was the latest posting to the Asus download site, or the V8, 2013 bootloader edition for JB. 4.2
Basically, I had tried several times that day installing CM11 and the gapps with CWM 6.0.3.1 (which ROM manager says is the up to date version? WTF?) to no avail. It kept giving me md5sum errors, and I couldn't find anything to easily fix that. CWM would also not respond to commands from ROM manager other than backups... If i told it to bootload and flash, it would just reboot normally... ADB also would fail, despite saying that i COULD connect to fastboot.
So i read on the actual CM forum that the newest TWRP 2.6.3.2 would do the trick as well, and tried that. But ya, once i booted into twrp, it threw a password query at me. I never set a password, so I pressed cancel, and that's when the partition showed up as blank.
I went to reboot, but it warned that I had no OS installed. That's about when I freaked out. It would see my microSD fine, but wasn't able to talk to /system to actually flash anything, and ADB would just give "error:closed" if I tried any mount commands there.
So ya, I invited my buddy over, and he recommended we try flashing an old CROMI-X, and it WORKED! sort of. It started to flash, even though a previous CM 10.2 and it's gapps (which I was already running and knew worked) wouldn't!
Then it froze installing Youtube, and after ten mins we held down the power.
And it booted back into CM 10.2 like nothing had happened.
Even though TWRP said I had succesfully factory reset AND wiped AND formatted the internal by that point. Lies!
So ya, I imagine it's a combination of pilot error, and TWRP being a little fluky. My question - where did that 87% CROMI-X flash go, and how can I get rid of it? And i reflashed CWM 6.0.3.1, but I'm still wary of going into the bootloader, just in case bastard TWRP is still lurkin

So it was definitely the old ASUS 4.2 bootloader I was using. I had no idea that dasunsrule32 wanted us to use his April 2013 bootloader for 10.2 as well, the site that told me how to put CM 10.2 on my tab said to use the old ASUS one.
Finally manned up and tried my first soft reboot, and it brought up the ASUS menu with the blue loading bar - it seemed like it wanted to go into bootloader. Then it went blank and the regular ASUS logo showed, and then the CM logo and booted. So i didn't walk away from this unscathed; something low-down got messed with...
Can I update the bootloader to his, despite the problems ive been having? How do I do that?
And why does ROM manager only offer 6.0.3.1??
And since CM11 is based on 4.4, wont it eventually be better than CROMi-X?

I haven't tried booting into bootloader, or even a full power down/power up yet. This is the device I use for school and right now would be a pretty sh**y time for anything serious to happen to it.
I am mainly afraid that TWRP hasn't left yet, or that I won't be able to access the CWM that ROM manager says I just successfully reflashed.
I don't really want to plug it back into the computer until I know more about what happened to it. Is it likely that the CROMI that we tried flashing or the old TWRP will cause me problems? Remember that CROMI said it was 87% successful (had loaded kernel and system and all that jazz)
And I have 64 bit Win7, it should have appropriate drivers

Jeez - where to start?
First of all: Do yourself a favor and ditch ROM Manager. It does not work well with the TF700 and several people have hard bricked using it. You have been very lucky so far!
Second: Do not flash anything until you are 150% sure you know what you are doing, you understand the requirements for your situation and have everything you need at hand.
Do not flash anything EVER if you do not know what bootloader version you have. That's like getting into your car blind folded and trusting that your GPS will drive you safely to your destination.
Every ROM has it's requirements in terms of bootloader version and recovery and they are usually clearly stated in the first couple of paragraphs in the OP of the rom thread. If not: Stay away from that rom unless you know exactly what you are doing!
TWRP 2.6.3.2 has major issues when formatting data from it. Stay away from it for now.
To find out what you can do to get a stable system back, you need to know where you are and what you have.
Boot into the bootloader (and do not use ROM Manager to do it!) and read the tiny script. It'll probably be 10.6.1.14.10 or .8
Post the result.
Boot into the recovery to check what you have installed. Versions matter!
The proper way of installing a custom recovery is in fastboot mode. Which is different from ADB, btw - you've been mixing those up I think.
Google "adb fastboot tutorial" and do some reading. Once you understand, get it set up on your PC, boot the tablet into the bootloader, connect both via original USB cable and test the connection with
Code:
fastboot devices
If it returns the serial number of your tablet, you are in business and we can continue from there.
Happy studying!

Alright, I have done some reading as far as all of this goes. I understand a lot of it better now.
So I'm positive now that it was because I hadn't updated my bootloader before trying through CWM. And TWRP obviously was no more useful.
I haven't quite checked what the bootloader version is - I think there may be something wrong with it still (given my weird boot-up) and I don't want to go there until I'm totally sure what I'm doing. I'd hate to hit bootloader and then realize something was seriously wrong, and my time was ticking.
However, I have never changed the bootloader since I used ASUS's one from their website originally - since it says v8, I imagine thats the .8 one?
Before I uninstalled ROM manager, I checked what it said my recovery was - and it said I had CWM 6.0.3.1 still, even though the TWRP fiasco has just gone down. I used ROM to reflash the same 6.0.3.1 from the device, and it said it was successful.
So before I begin, could i possibly ask a few questions?
1) Could I have corrupted the bootloader?
2) Can more than one recovery exist? Is it maybe true that CWM 6.0.3.1 would be the one I will boot into if I went into recovery? I REALLY don't want it to be TWRP again as it might not survive the experience (I had put TWRP on via fastboot). Should I just get to bootloader, flash a new recovery right away and go from there?
3) When I go to finally solve it, what are the hypothetical steps I should take? Right now, as far as I can tell, it will be:
a) Make sure all drivers are working, and files (including backup) are on my PC.
b) reboot into bootloader, check version.
c) flash the 10.6.1.14.4 bootloader
d) reboot
e) reboot into bootloader
f) flash CWM. 6.0.4.6
g) reboot
i) reboot into bootloader, into recovery, then flash CM 11 and gapps
j) reboot
Ya? No? Any help would be appreciated

1. No, your bootloader is still good because you still can boot into your system. You need your bootloader to initiate your hardware before your OS is booting.. I am very sure that is the case but it would be nice for someone to confirm it...
2. Your recovery partition is too small for two custom recoveries to exist. So it is almost impossible for you to have two recoveries..
Before you want to go further, it is easier to find out your bootloader and recovery versions so you know what is the next step that you need to do. Otherwise, it is just a guess or a shot in the dark... I think that you are fine but you need to wait for some experts to confirm it... Good luck...:fingers-crossed:

Sorry hahah, I know I must seem really frustrating...
I have held off for 2 reasons:
1. The first time I did a soft reboot after my fiasco, upon boot it went through the first series of steps trying to load into the bootloader, but then booted fine. Another time a few days after, it rebooted while i was using it, and just went blank after the asus logo. Holding the power down caused it to boot fine. Still, neither of those had ever happened before, and I am pretty sure that some point along the line of bootloader-->OS something is broken. Hopefully on the OS side.
2. I am not going to attempt to boot into recovery until I know that it isn't the same TWRP 2.6.3.2 that got me into this whole fiasco. I know it sounds like a catch 22, not wanting to reboot into recovery to check what it is, but I have NO IDEA how to get out of this TWRP as it stands. I had to flash a CROMI (which failed at 87%) and hard reboot. Not willing to go out on a limb and assume that hard-reboot will work during any step of that process.
So, why do I have to check it? Can't I boot into bootloader, flash a new bootloader, flash a new recovery, and then reboot normally? Assuming I'll be able to establish fastboot (drivers still work, so fingers crossed on that one).
Hi guys, I'm normally the one who reads these forums, not starts them, so i'm in pretty desperate help.
I have a Samsung Nexus S phone that somehow got stuck in a bootloop after my dad attempted to fix the problem by wiping everything he could from the recovery; cache, system, data, factory reset. I am able to access fastboot (obviously). In fastboot mode, the only 4 options it gives are POWER OFF, REBOOT, RECOVERY, REBOOT BOOTLOADER. None of these options leads to any progress. Only one that makes sense is to click and run recovery. When recovery loads, i can:
Reboot system now
apply update from ADB
apply update from sd card
wipe/factory reset
wipe cache partition
I recently rooted and custom ROMed my Galaxy J7 Pro, and as you experts may know it wasn't too easy finding the correct files or even the support for it.
I know you have to have developer options enabled and OEM and USB Debugging as the prereqs for rooting, but this phone has nothing. I'm not sure what to do. The bootloader is locked and I obviously can't enable developer options. I guess where I'm stuck is how i can flash a custom recovery like twerp for a phone that has a locked bootloader that can't be unlocked through developer options.
As I'm writing this, i was thinking, can i prepare an SD card with the lollipop OS for the nexus to install and run on. Ive already wiped the internals and cache of the phone, meaning there is nothing on it?
Help would be appreciated, bringing back a phone that has the potential (working hardware) to run would be great.
Just do a manual restore using the google factory images (google them, first result usually and a VERY user friendly page, thanks google!).
Don't use the script, just reformat everything via fastboot, then manually flash the images to their respective partitions.
"cd [path to unzipped images]"
"fastboot format /[partition] ext4"
"fastboot flash /[partition] [path to image]"
and so on and so on. Then after, "fastboot reboot". I assume you've found a fix by now but maybe someone else will stumble on this. Keep in mind, I'm writing this from memory and with no drivers or way to test this on my mac, my Nexus S is coming in the mail soon so take what I say with a grain of salt and try to double check the commands. For the most part however, they should be correct. format, reflash, reboot. All you should have to do.

I have the same problem.I know this was 4 years ago but as a noob I find that guides tend to assume greater levels of knowledge than I have. Trying to bypass FRP as I think this is what is causing the "system error" message when I try to access play store or Google plus. I haven't even been able to unlock bootloader or root phone . In fact I find "fastboot" and ADB downloads a mystery? How to get them to work?
