No OS, TWRP fails to flash .ZIPs - Asus Transformer TF700

Hey guys,
I'm having some trouble with flashing a new ROM and now I've soft-bricked my device.
I was trying to flash from CROMi to CM11 so I wiped data, cache, dalvik using TWRP. But when i tried to flash CM11 M9, i would get the "failed" error. I tried flashing other ROMs but same result - "FAILED".
So I thought maybe it was the recovery. I downloaded a CWM recovery (in .zip) and tried to flash it. FAILED!
I tried to restore my device using the "Recover /Downgrade from Jelly Bean to ICS/Clean Factory Restore with custom recovery" method from this post. Since it is basically flashing the stock ROM, naturally it fails.
Now I'm out of ideas. How can I save my tablet?
Thanks for your help guys!
PS: I'm trying to install CMW via fastboot. When I press power + vol down, I get to the screen with "RCK, Android, Data Wipe"; I dont see the USB icon. How do i boot into fastboot?

You are in fastboot mode when you see the three icons. Read the tiny script.
Except for CM11 M9 you did not give us anything to work with.
Give us the version numbers of:
- CROMi-X you were running
- your bootloader
- your recovery
My best guess is you are trying to flash something with an incompatible recovery, but that's just a wild guess.....
And stop flashing willy nilly until you know what's going on. You can brick this tablet if you try hard enough, you know....

Hey bern,
Thanks for the reply.
My tablet got really slow so I decided to flash CM 11 M9, which is what I use on my Note 3.
I'm running TWRP 2.6.1.0. Not sure which CROMi I was running because I can't boot into Android. I did a data wipe prior to (attempting to) flashing CM11 and now it boots straight to recovery.
I read that TWRP is not compatible with CM11 and that I should flash CWM. But TWRP fails when I try to flash anything so I'm thinking I should attempt ADB sodeload or terminal command and load that way?
Thanks again
Edit: I downloaded CM11 M9 for tf700. I also tried various nightlies in case my original download was corrupt. It ends in failure

Hi berndblb!
I'm also having this problem and I see that you're quite active in the TF700 forum that you could help me out. I wouldnt say I'm an expert but I have tinkered with phones (mostly Samsung and Nexus devices) in the past so I am familiar with ADB, terminal commands, flashing ROMs, etc.
I'm running TWRP 2.6.1. I was running CROMi-X (not sure which version) and wanted to flash OmniROM. However, TWRP would show "error flashing zip" and "failed" in red. I tried flashing a few other zips including TWRP 2.7.1.1 and CWM (I readTWRP is not compatible with some ROMs) and I would still get the error and "failed".
So now, I can't boot into the OS to flash a recovery via fastboot or via CWM Rom Manager, nor can I flash anything in TWRP. I also attempted to flash TWRP 2.7.1.1 via terminal command
HTML:
dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4[HTML]. I loads but it doesnt install when i restart my device.
What do you think I should try next? I'm getting pretty desperate at this point. Is my device bricked-bricked or can i salvage it?
Thanks!

Right now the most important thing is the bootloader version ....
On the bootloader screen upper left there is a bootloader version in really small print ...
This is what we need to know ...

Exactly.
I also would like to know how you performed the wipe you mentioned. The tablet booting only and straight to recovery would indicate that you used 'Wipe Data' from the bootloader???
Also, do not use ROM Manager. It does not work well with the Transformers and can cause a lot of problems.
I have a feeling another user is going to benefit from your excellent unbrick guide, Josh...
Aren't you glad you wrote it?? [emoji12]

Hi Josh. All i get is the Asus starting screen and "your device is unlocked". Power + vol down doesn't not take me to bootloader.

No boot to recovery ?
No bootloader ?
No nvflash blob backups ?
If that is the case then you are not looking good ...
There is no way out of this one ...
We need fastboot or recovery one or the other ..
Sorry for the bad news ....

Do you have adb access when it boots to the Asus splash screen?

Cannot Flash anything!

Alright, so, my tablet decided to one day just cease stop working. The recovery for some reason can't flash anything now, is used to be able to flash a backup, but not anymore. It used to be able to boot past the animation, but not anymore. I cannot flash a ROM from recovery because it says that the file is bad (and please, don't tell me to check to see if the md5's are correct, they are, I've triple checked.) I've flashed CWM recovery and TWRP recovery, and TWRP cannot fix permissions, but CWM recovery can, but neither can flash a single ROM. I've tried sideloading a rom but i get this error from the CMD window
Code:
* failed to write data 'protocol fault (no status)' *
. I'm at my wits end here. The bootloader is perfectly fine, it works 100% but I can't flash a single thing from recovery. I've flashed non-corrupted recoveries, and still I cannot flash a thing.
You have flashed the latest TWRP via fastboot and it still wont flash roms? Also, what bootloader are you on?

What tablet do you have?
From where did you download which recovery for which Asus tablet.
Sounds like the recovery version doesn't match the device.

Asus Tf700 32 GB. I got the recovery from the TWRP website. In answer to the boot loader question, I have no idea how to check. All I know is that I can choose between RCK, Cold Boot, Fast boot and Wipe Data.

Have you ever unlocked the bootloader? (If not: do so by searching on Asus' site for the Unlock Bootloader Tool v7) It's a simple apk which you install and then check and let it unlock.
Only then, you can start flashing!
If you already have unlocked, maybe you sent it in (?) Or flashed an official Asus rom (?), you might want to unlock it again.
Let us know if any of these answers above helped

If you have the 4 icons that indicates JB.
Sounds like the custom recovery is not installed if your on the RCK icon and press the up volume rocker and nothing happens.

Unlocking it would require an OS to be installed, but none is installed because I was wiping to install a different ROM. I have unlocked it. In response to the boot loader, yes, it has 4 icons. So I guess it is the JB boot loader. When I go to RCK it does boot recovery but from there on its unable to open any zips besides any backups I have. When I reload a backup it doesn't install the OS, but it restores everything else.

Can you get adb shell access to your recovery?
Which ZIP are you actually trying to flash? What is the exact error message from the recovery? Try running md5sum (inside the adb shell) on the file you want to flash. Check the output of "mount". Check if /cache/recovery/log contains interesting info.

Alright, I'll have to try that when I get home in about 3-4 hours. I'll get back to you on that. Also, I noticed last night that when I was on fast boot, it would stay stuck as waiting for device on the cmd window. I'm not sure if it was my computer that didn't detect it or a new symptom. O hope its just a fluke!
Alright, here's the log from my recovery.

OK, I assumed that you're not using data2sd. 1. Make sure your microsdcard is good (reformat and recopy your backup or rom if needed),2. Boot into twrp and wipe cache, dalvik cache, factory reset, wipe system, wipe internal then finally the most important part, FORMAT SDCARD. Now reflash a new rom or try to restore from backup. I would try step#2 first. Good luck.
EDIT: format sdcard instead of wipe sdcard.

Tablet Not Mounting

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!!!!!

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?

And since CM11 is based on 4.4, wont it eventually be better than CROMi-X?

Can you still boot into fastboot mode on your tablet and can your PC see the tablet in fastboot mode?? What is the OS on your PC??
i dunno

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

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

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).

[Q] Only fastboot accessible to flash / restore my TF700

Hello,
My TF700 was on a CleanRom (2.3 i think), for a while, i decided to update.
- I installed the latest CWM (via fastboot) and flashed a Cyanogen 10.2 "stable", but my tablet freezed very quickly after successful boot, i tried some reboots and get same problem.
- I tried to install a stock ODEX root ROM, the tablet freezed at asus logo
- I flashed TWRP instead of CWM, it doesn't helped
- I tried wipe data and cache with TWRP, then my data was not accessible anymore and TWRP was unable to re-create it
- I searched on forums and found on this one that flash a boot.blob file can solve the problem
- It doesn't and now CWM and TWRP refuse to work ....
So i post here before getting my tablet completely brick.
At this point, i get access to fastboot / abd, CWM load but don't work (reboot when trying to do something), TWRP don't load.
Any suggestion to get back to a Stock ODEX rooted rom ?
Excuse my english ...

Sounds like you are on an old bootloader. Flash the stock rom from asus by unzipping the zip you download from their website and placing in the root folder of your micro sd and then go into rck from the bootloader menu (power + volume down whilst booting)
Or you could just flash it from recovery....

I buy a tf700 with cm 11 a few days ago i am really interessted on how this steps works. I really want to make it unbrickeable, But i dont really understand how it works. I can not enter in fastboot. at least i got cwm interface when rebooting with adb into recovery.
Can u explain how you did it?
It invovles flashing a modified bootloader and the flatline recovery and then using Wheelie to generate your nvflash blobs.

Stuck in boot loop, fastboot and recovery accessible
Hello,
I'm having a similar issue and I need help! Initially my tablet was rooted with Cromi-X 5.4. Then I decided to try Crombi-KK.
Here is what happened:
- Updated TWRP recovery
- Did a full wipe as recommended
- Flashing got stuck at the Crombi-KK loading sign
- Tried to reflash but TWRP wasn't detecting data partition anymore
- Instead installed the other recommended recovery CWMR.
- Flashed Crombi-KK, it worked. Played around with it for a few days, it was wonderful, fast and responsive.
- Battery died out and when I turned it back on I got a UIDs system inconsistent error.
- I found online many recommendations to reflash so I tried to do that
- Since then I'm stuck in a boot loop. I see the initial "bios" Asus logo then it restarts over and over.
- I am able to access bootloader and recovery
I've tried reflashing the asus stock blob. I've tried wiping the data through CWMR but it starts working and then it restarts. I don't know what to do anymore, so if anyone can help me, I would really appreciate it!
Thanks
Which recovery and bootloader version do you have now?
A (for KK) outdated bootloader seems the most likely culprit.
You can try save the recovery log when you flash or grab a logcat of the bootloop, but probably it'll only tell you that the recovery cannot mount /data.
Determine that you are on the correct bootloader, if not update it. If you're lucky the tablet will start right up. If it doesn't, formatting /data is the only way I know to get it back. Not just wiping - formatting it. You will loose everything on internal SD, so I hope you have a nandroid you can restore from later.
If you use TWRP 2.7+ be aware that formatting can take more than an hour. Let it finish!
For good measure, download CROMBi-KK again, check the md5 and then flash that file.
I'm on 10.6.1.14.10 bootloader which I think is the latest one
I have 6.0.4.7 CWMR
I'm trying to format data completely but when i do it in CWMR it starts and then the tablet reboots on it's own after a couple of minutes.
How can I retrieve the logs, I never had to do it before.
Thanks for your help
Mhh, getting a little more complicated.
Your BL is ok...
What do you see in CWM when you go into Mounts and Storage? What is mounted?
The recovery logs are under Advanced > show logs.
I'm at work now but from what I remember the only thing mounted was the cache. I'll double check tonight. Do you think there's any hope or I have a brand new paper weight?

Can you fastboot flash twrp?
It's much much better than CWM, has its own terminal and will be easier to offer the correct format command.

So I flashed TWRP and when I go in mount/storage everything is selected except for system. Should I do a format data from the wipe menu before flashing crombi-kk again?

To be in the safe side, yes, that is what I would do. TWTRP 2.7.+ takes a long time to format and it may seem the process got stuck. Give it at least 90 minutes to finish.
Then reflash CROMBi
I'm back up and running !!!
This time installing TWRP, everything was mounted (maybe my previous flash before CWMR wasn't good), did a format data, waited until it was done, flashed latest Crombi-KK and going through setup now. Hopefully won't have the same UID issue on next shutdown. I didn't enable fsync or journaling so hopefully it won't happen again.
Thanks both of you for your help!
Good deal! Happy for you!

Can't get my new tf700t to root or install recovery.

Hey guys.
I just got a very nice condition used TF700T. I am trying to get recovery to install so I can flash a rom. I used the Transformer Toolkit to unlock it, which worked, it says device unlocked when booting.
But I absolutely cannot get it to Root, or flash recovery. If I try using debugfs root generic 2.3 it fails to write everything. If I try to flash any recovery with the toolkit it downloads and says flashing but just sits at about 25%, it boots my device into the screen that says usb fastboot mode with the three icons that say RCK Android and factory wipe. If I click the RCK it says rebooting and then goes to android mascot installing icon, but then the one with an X and error appears. What on earth am I doing wrong?
Is it the latest 4.2 update locking me out? Can I downgrade? I just can't get anything to root or flash recovery no matter what I do. I feel a little defeated being a long time member and 3 phone habitual rom flasher :crying:\
Any ideas what i'm missing?

Well I tried TWRP 2.7.1.1 I believe and also CWM , and Phil's custom touch CWM that all three are options to flash with the all in one ADB Toolkit app via USB from windows (http://forum.xda-developers.com/showthread.php?t=2094746)
How do I do the Fastboot method? I read about that, but have no idea how the process goes. I'm ok with skipping root and going straight to recovery and a rom because I can just flash superuser after if the rom isn't rooted already.

I wanted to try an app I used to get twrp onto my LG G2 for the first time called "flashify" that worked like a charm. I just installed the app, downloaded the twrp file and flashed it then it reboots to recovery, but it requires root as far as I know. Does unlocking the boot loader allow things like this?

Unlocked bootloader is allowed you to install the custom recovery so you can install the custom ROM, I believed..... You can check this guide out to see if you can setup your fastboot/adb. It is very easy to follow for the beginners, good luck....:fingers-crossed:

Once you unlocked the bootloader you can flash a custom recovery and after that - the sky's the limit.
Flashify works great, and it is a wonderful tool as long as you're able to boot into Android.
My problem with Flashify and Goomanager and TwrpManger is that it saves users from setting up a proper ADB/fastboot connection from PC to tablet.
As long as you can boot Android, these apps are great. But what if you can't? Once the tablet doesn't boot it's so much harder (and often too late) to get the correct drivers installed for ADB and fastboot.
So if you flash your recovery with any of those apps still make sure you have access with ADB and fastboot from your PC.
You will regret it if you don't - I (almost) guarantee it.
That's an excellent point. Thanks. I did actually get the Fastboot method to work. The problem was that I kept clicking into RCK recovery when I ws supposed to just leave it on that screen to push twrp instead. I got recover and just got done doing a backup. I'm about the flash my first rom (http://forum.xda-developers.com/showthread.php?t=2672751). Do we need to do factory reset / wipe data/system etc? The instructions on the ROM post say to just flash it from twrp so I'm guessing it has a built in wipe feature during install?

The instructions in the OP actually say that you have to do a full wipe (Factory Wipe) in TWRP coming from a different rom base. Which would be you unless you had a version of CROMBi-KK installed prior to this.
It's the default selection under the Wipe menu in TWRP. Just do that and then flash the rom and your ok.
Do not use the Factory Reset option from Settings or the Wipe Data option from the BL menu! Do this in TWRP only!
Cool thanks. I figured so because that's the norm with roms on all my phones. Thanks a lot for the help guys. So happy to be get KK running on my new toy!
Just wanted to update. KK 4.4.3 rom flashed and booted in. It's much nicer. The stock was a little laggy, and KK breathed a lot of new life into my ancient single core 1.0 ghz Galaxy S that I use as a music player so I figured it would help make the tab real nice and snappy too. Gotta go now, much fun to be had!!

Before posting, please use the forum search and read through the discussion thread for [RECOVERY][TF300T] TWRP 2.8.7.0 touch recovery [2015-06-23]. If you can't find an answer, post it here, being sure to give as much information as possible (firmware version, steps to reproduce, logcat if available) so that you can get help.
Thanks for understanding and for helping to keep XDA neat and tidy!
Does TWRP 2.8 (latest version 2.8.7.0) okay to start out with? Meaning, if we are at the latest version of stock (ASUS build JOP40D.US_epad-10.6.1.27-5-20130902; Android 4.2.1) and we are going to flash a custom rom for the first time, the latest versions of TWRP won't brick our devices?
It could be that I'm just confused because there were lots of older versions that reference individual Android builds (JB vs ICS). And people would say "if you have X version of Android, use Y version of TWRP or you're gonna brick it".
Can't enter twrp but everything ok

I got sent here, so I'll try again.
I'm a little confused now, because I can't understand what is happening to my tablet. Let me explain step by step what I did, maybe one of you can figure out what is wrong.
I was running CM11 M12 with TWRP 2.8.1.0 and wanted to try the new Android 5.1. I decided to go with the latest Omnirom and found out I needed at least TWRP 2.8.5.0.
So first step would be to update TWRP. When I got at the TWRP website I read that there was something new in TWRP 2.8.4.0, so I decided to first go from .1 to .4 and then go to the latest .7. An upgrade to .4 went fine through Fastboot. Then I thought I could try the new in GUI recovery flasher, but I didn't understand it properly so I chose to go safe and flash the .7 through Fastboot.
I guess that's where I went wrong. The tablet went to recovery just fine, but in TWRP it couldn't access anything anymore. "Unable to mount" on everything. Internal storage was 0. It didn't boot to the ROM anymore.
So after some tinkering, not really sure what I did anymore, I got my access to the FS again. I had the CM11 M12 ROM still in the MicroSD, so I ran the "install ROM procedure" for that one and it booted again.
Only now I don't seem to have a recovery anymore. I can get into Fastboot, but when I send the "fastboot -i 0x0b05 flash staging twrp.blob" the tablet hangs itself. Holding power revives it and it boots to CM11M12 again. I tried to flash different TWRP versions (.4 .5 .6 and .7) but no sigar.
Does anyone have an idea how to get my recovery back?
Edit0: I tried to install the TWRP manager from the store and get a recovery from there, but the app doesn't work. It hangs when I try to tap on the "Recovery version to install" option.
Edit1: I followed the link in the post above and solved it. Next thing I did was flashing the .6 TWRP recovery and it stuck. Time to wrestle with some new roms! Thanks!
Edit2: Back to square one. The TWRP can't see anything in my internal storage. Is my storage memory going dry? "Unable to mount ###" shows up for every partition.
Edit3: And now it can see in my internal memory again... Hardware failure?
2.8.7.0 on tf300t reboot/shutdown does not work
hi, thanks for all your effort!
i just used fastboot to load 2.8.7.0 on a stock tf300t. it seems to work fine with one exception, when I choose reboot system or shutdown, but result in me booting back to twrp immediately. the only way i can shutdow/reboot is to hold the power key for 10s, then press it again to boot
everything else seems to work ok (flashing etc)....
any ideas whats going on?
thanks again

Hello
Can someone help me please?
For the moment i have TWRP 2.8.0.1 and i want to update it to 2.8.7.0.
First of all, i tried to update it with twrp manager.
So i open twrp manger
The install recovery screen opens and i choose for "Install Recovery".
Then i'm redirected to jmz software and then i got next screen:
Forbidden - you don't have permission to access /tf300t/ on this server.
What i'm i doing wrong?
