Hi
At the weekend I tried to update my TF300T from CM10.1 to CM10.2. That didn't work as I ended up in a boot loop. Then I thought, maybe I need to flash the latest system blob.
So I did that, only to find that I then couldn't install anything from zip or sd card as the recovery would not mount anything at all. Still got fastboot, so I've tried TWRP 2.6. TWRP 2.5, TWRP 2.4 and CWM, none of them will mount anything at all.
So I find myself with stock ROM, but no way of rooting or installing any custom ROMs.
I'm sure I've made a bloop somewhere, so all suggestions to resolve welcome!
Thanks
Rob
What is your bootloader? Sometimes, if you reflash the same recovery, it *may* work properly the second time around.
I am using TWRP 2.6 with my 127.5 bootloader, just for your knowledge.

That was the tip I needed - I knew I had the right bootloader but I had downloaded the wrong TWRP (I had flashed the JB version instead of the 4.3 version). Doh!
Now flashed CM10.2 and is running Android 4.3. CPU-Z tells me I'm rooted though at the moment I can't get any root apps to work with SuperSU. I'll leave that for another day!

This is the story
I first installed Unlocked bootloader from asus, CWM recovery for tf300t, and then i used the update.zip to gain root access
I downloaded the CM nightly build, used CWM to backup, then flashed the CM ROM.
It was stuck on CM boot logo for about 30 min, so i restarted and cleared my cache.
I tried flashing again, and it was still stuck on boot.
I then restored to my backup, and now it is stuck on the original ASUS boot animation.
What do I do?

restore with cwm,ifyou can, to earlier version,working
then remove ClockWorkMod Recovery, by fastbooting TWRP instead...much more reliable (team win recovery)
then to root, theres a theres a batch script tool, that,when tablet is connected to pc, will run and reboot the tablet several times, rooting it.
ill look for the link, its in the forums here, debug,defug..something
there are other methods,that worked the best for me...
CM had been having issues, install CleanROM 2.1 HAS THE JB UPDATE V13 in it. its smooth

I am having the same issue installing any ASOP roms on my tf300t.
I have the TWRP recovery, gained root by flashing.
I can install ASUS based roms like CleanROM fine, but I cannot flash any ASOP roms like CM10.
Just curious on what is preventing us from doing this. Especially when our devices are supposedly "unlocked" with custom recoveries and root.
If this device still continues to be this locked up, I might just have to sell mine when the GN2 comes out.

First declare your bootloader. Have you ever been on a jb-rom, stock or otherwise?
Looking at git for cm it appears the kernel is 2.6, so I would expect that is not a jb rom.
cwm has some issues on this unit.
get into cwm and use fastboot to flash twrp for the proper bootloader you have.
or get into fastboot by use of power and volume down
at that point you can twrp a rom into place; probably not to restore your backup as twrp and cwm have issues reading each others backups.
Good Luck!
Note: If you can power up and access recovery (cwm in your case) you are not bricked and should be able to recover. I have as well as many others. Take your time and go a step at a time! Make back ups and make sure you have fastboot and adb access to your unit! If you are still ics bootloader consider nvflash once you have this mess sorted.

This is a known problem... once u get the OTA asus jb update, u can no longer flash any aokp or cyanogen jb roms. This is due to the kernel in these roms which are based on ics but since uve installed new ota jb bootloader it will not work and get stuck on boot screen. Restore in recovery will not work either. U need to download latest asus firmware and flash it then fastboot a recovery (i recommend twrp) and reroot.

Ah, ok. I have the JB OTA update so i have the latest bootloader :/
I restored my nandroid of stock and it worked fine.
Just flashed CleanROM which is running great. Cant wait till the CM team gets the JB bootloader worked out as i have always loved being ASOP. Any info on when it might happen?

Great that ur nandroid worked! I know they r working on it... dont really have a time frame... just be on the lookout
I was on locked on stock OTA JB.
I unlocked a few days ago, then last night flashed TWRP. Created a nandroid, then rooted.
Today I've spent several hours downloading ROMs, doing Titanium backups, surfing forums, backing up my personal files etc. i.e. using my tablet normally without problems.
I decided it was time to flash a ROM so booted in TWRP to create a fresh nandroid. Then when it finished I rebooted the system with the plan to copy the nandroid to my pc.
The tablet booted, but then after 30s or so rebooted. It's now stuck in this boot loop. So I tried a cold boot, and then restoring the latest nandroid and the problem persists. I'm currently trying to restore the pre root nandroid I made.
To recap - I am on stock OTA JB, with TWRP v2.3.1.0 recovery. Any thoughts?
Ok just to update - the pre root nandroid seems to be stable at the moment. So... What to do?
Should I reflash the recovery? Try a different recovery?
Any ideas why the nandroid would be borked when the system seemed stable when I created it?

Question: Does TWRP actually root the TF300? Mine is unlocked but I am looking for the easiest way to root the device.
No it doesn't, it just replaces stock recovery and allows you to gain root.
You could start your own thread. Or, you could read the thread in Android Development that gives clear instructions for noobs to gain root and install TWRP or CWM.

which ROM were you trying to flash? was it a JB rom?

After you install TWRP, you just need to flash a root zip file with TWRP to gain root..

Since this thread got immediately hijacked i'm not sure but I'm going to assume this part of your post was aimed at me...
I wasn't trying to flash a ROM at all. I hadn't even got that far. All I'd done was flash the recovery, root it and then create a nandroid. It was creating the nandroid that seemed to trigger the boot loop, even though that makes zero sense.

can you get back into fastboot connected to your PC?
I'd try to re-flash TWRP. Also make sure you are using the JB version, not the ICS version.

I just unlocked and flashed TWRP on my tf300 (with the OTA JB update) this morning, and everything is working fine. I also flashed a root file without any issue.
I reflashed TWRP and re-rooted it seems to be OK.
Then I found I couldn't get any ROMs to work - they all froze at the boot screen. The solution to that problem lies in flashing the US update of JB rather that the WW. Now I'm running Hydro with Untermensch's kernel.
One thing I did notice with TWRP 2.3 is I get the error "can't mount /storage" in the log whenever I do anything. A bit of research suggests this might be an issue with TWRP 2.3, not present in 2.2. I wonder if that is what was causing the boot loop issue I had previously.
I can't seem to find a blob of 2.2 to downgrade to so I'm living with it for now and hope it's not going to cause problems down the line.

Good that TWRP always using the same names for a DL Link. So here is the 2.2 for JB Bootloader
If you are looking for ICS just edit the dl link .

Hello, I am having some problems installing a working recovery, here is my story... So first the device was 10.6.1.27.5 and its unrootable, so i downgraded to 10.6.1.15.3, where I installed TWRP recovery, and flashed CM 10.2 ROM, but it was too glitchy, so i wiped all data, and fastbooted 10.6.1.15.3 build and stock ROM. So I am now stock,
I am rooted using MottoChop method, and I cant install a custom recovery... I tryed to install TWRP 2.5.0.0 thats the version I was on before, and also tied 2.6.3.0, when flashing the .blob My device turns unresponsive, even when rebooting it with fastboot.
So left with no choice i tried flashing the .img one for JB, (Note: It is currently NOT a OTA update, but manual, so i used the 4.2 first)
I was Able to Flash the custom recovery 2.6.3.0 JB.img and it booted up and worked fine, but then it couldnt mount anything,
I was getting error message:
E: Cant mount /data
and so on... I then tried to flash 2.5.0.0 and got the same result.
GooManager cant find a recovery script for this device...I flashed the TF300T, since thats the kind i have not TF300TG
Im really lost now... I tried ClockworkManager to find a recovery and it said the same thing, I dont want to flash a CWM with flashboot since i here It is terrible.
Any Help Is greatly Appreciated
I notice that alot of these problems, I end up fixing myself... I fixed the issue
But If anyone ever comes into the same situation, heres the fix...
UPDATE to 10.6.27.5 (Yes newest version) Im using US...
Install openrecovery-twrp-2.5.0.0-tf300t-4.2.blob IMPORTANT dont flash the JB version because its only for OTA updates
Open recovery and TWRP will prompt you to install, and beleive it or not, but apparently you can root the newest version,
Just not With MottoChopper and other quick root methods!
If you have any more question, post!
I have the Nvidia Shield 16 Gig Wifi tablet and Ive only had it for about 2 months. I wanted to unroot and completely go back to out of the box settings. I flashed the stock recovery, and boot. When i flash system.img it says insufficient space. Im really freaking out over this. I now have CWM running as recovery, but im stuck in a bootloop/softbrick. Ive had this with other tablets before but it was fixable, Im stumped with this one. I really need help here. Please and thank you for help, I need it ASAP.

So, basically you left your shield tablet without a rom installed? If you have CWM recovery, you could flash a Full OTA found here http://forum.xda-developers.com/shi...k-recovery-images-ota-library-guides-t2988881
It happened to me to. So I downloaded a Philz built in Jan (I googled it)**** and I flashed the full 2.1 ota.
You could flash the TWRP 2.8.5.0 found here:http://forum.xda-developers.com/showpost.php?p=58864006&postcount=90 and then flash the full ota.
Then, Im thinking, you could flash stock recovery. I'd recommend flashing TWRP though, I had a problem with CWM and I could not flash full 2.1 OTA with it.
PS: Did you try wiping system from CWM and then flashing system with fastboot?
****EDIT: I found the Philz I used: https://goo.im/devs/playground/shieldtablet/Philz_Touch-01-02-2015_14.18-TN8-WiFi.zip
but Ive moved forward to TWRP since I couldn't make nandroid backups with it.

Okay I have to thank you a ton for getting my tablet working again. Only problem now, I cant system update anymore, I get an android guy with a red warning sign in him. Any suggestions?

Probably because you have custom recovery still or you are rooted.
The android red guy happens bc you are rooted (it'll happen even if you have stock recovery).
To system update, you have to be without custom recovery AND unrooted.
EDIT: Im theoretically speaking. I am rooted, therefore, I dont update via OTA.
i tried to recover to factory but i am stuck at system.img which dun seem to be copying into my tablet i manage to flash twrp in and wat else can i do to make it working again?
thanks
Hey androids, I submitted this question as a reply to the guide thread already earlier... just thought it might get noticed in this forum alittle quicker... any help would be appreciated
I'm working on a recalled tablet that I rooted to keep using, and up until recently the ROM i had installed on it worked famously (bliss pop with android 5.1.1). Now, I was having some issues with it and thought "Well, i'll try out a different rom!"
So, I already had root (obviously) and I had already successfully installed a rom to this tablet... Using TWRP (both the 2.8.x.x I used previously and the newest one available for the shield) I have backed up, wiped, and flashed the images to 3 different roms + gapps for the appropriate versions...
first, I was going an issue with it mounting the \data partition so it wouldn't flash anything... then I repaired and rewiped the partitions, and got (what appeared to me in the logs) a clean and successful install of the roms. Each time I successfully flashed a ROM and GAPPs zips I would go to boot the ROM and my table would sit on the "NVIDIA" boot screen forever, never advancing to boot the ROMs.
I was worried that I had made a mistake and bricked the thing (though, it's been on borrowed time anyways being a recalled tablet). But I was able to force shutdown the tablet and reboot it into TWRP for another try. Each time I cleared the previous flash, wiped the cache and system partitions, and would get another clean install... but each time, it would get stuck on that same boot screen....
Anyone have any suggestions? thoughts? ideas? fixes? answers?.... anything? lol
Thanks folks!

Is the newest TWRP *not* a MM bootloader?
TWRP is a recovery. A bootloader is a bootloader.
This is covered in every rom thread that updated from L to M.

I'll re-look, the guides i've read have only covered flashing TWRP, then using them to flash the ROM and GAPPs... Which is what I did the first time I rooted it and put on a custom ROM... though maybe I didn't delete the original bootloader the first time and did so accidentally this time?
Thanks for the heads up though people, we'll see if I can straighten it out now that I know what I'm looking for

Ok, so I've downloaded the shield recovery zip, flashed the boot.img to the boot... nothing, then I read on one of the guides here that the "blob.img" is the bootloader... but the zip has a blob, without the .img
So I then attempted to add .img, and flash it to "boot" in TWRP, and there was an error, saying the file is too large...
do you (or someone else) know where to find a guide on where to find/how to flash a MM bootloader?
thanks
Ok, so I found guide with links to the latest firmware update; I flashed it, rebooted, and now I've gotta past the "Nvidia" boot screen into the Bliss boot screen... It's been here for a couple minutes now, gonna give it alittle bit and then try to install the other ROM I had tried.
