[Q] TF300T, TWRP and ROM issues - Transformer TF300T Q&A, Help & Troubleshooting

Hola banditos, I am new here, and not really that big into android, so forgive me if I do not refer to something correctly. I am currently having multiple problems with my Asus Transformer pad. A few months ago I purchased said product and rooted it. I had a few minor issues but eventually got it working. Flash forward to yesterday night at around 10 PM, and I had wiped the system and removed the Operating system. "No problem" I thought "I can just download the Jellybean firmware from the asus website" ( I had done this before.)
I downloaded the firmware, put it on my SD card and flashed it. The only problem was that I had flashed the Japanese version of the firmware onto it.
At this point, TWRP apparently thought it would be hilarious to stop working. Upon downloading the US version of the software and loading it onto my SD card, TWRP was no longer able to mount the SD card. That my friends is the major problem.
I have checked on my computer, and the SD card is still functioning. I have went into the Japanese OS on the Android and it is still accessible and functioning. I have downloaded multiple versions of TWRP, different recovery kernels and tried multiple solutions through other threads. I have tried reformatting my SD card to EXFAT, Fat32, NTFS and regular FAT. I have tried putting the firmware on the internal SD card and loading it from there. It recognizes that the firmware is there, but fails to install it. ADB also fails to recognize the device (I have everything set up correctly on the PC but it still fails). Fastboot is working fine though.
I have crawled through web page to web page looking for a fix. About 7 hours in total, and I am yet to find one that works.
Help me out here.
My gear:
64 GB sandisk SD card
Asus tf300t running a japanese Jellybean 4.2.1
TWRP 2.6
You're my last hope

There is another way! Inside the us software zip there is another zip inside that zip is a .blob file extract it to the directory where adb and fastboot are on your pc open up command prompt and cd to your fastboot directory: now type: fastboot flash system blob
This will take some time!
Then flash twrp and open it then wipe data system cache dalvik cache and then flash the firmware via twrp reboot!
Sent from my sensational HTC Desire C

I have grabbed the blob file from the US firmware. Upon using the "fastboot flash system blob" command, I get the message < waiting for device > I have waited a half hour, and it is still there. am I doing something wrong?
Edit-
I have since got the fastboot to work after some research. When I went to wipe the data system cache and dalvik cache, TWRP said that it had failed. TWRP still failed to recognize my SD card
Edit Edit-
Again after more searching, I have found a TWRP version that has recognized my SD card. However, One problem still remains before I am finished. I am still unable to flash the stock firmware. I navigate to my External SD card in TWRP, select the firmware zip file. Almost instantly it says that the install failed. Any ideas?

I can't see files in TRWP recovry after installing MaximusHD

Hello
I got my HTC One S s4 a couple of days ago. It was unlocked. With the guides here I managed to root it and S-off and ass I was feeling confident, I installed Maximus HD 10 rom (I think I had android 4.0.1). I followed the instructions and I even got the error described in there.
My problem starts here:
Code:
Make sure that installation was successful and press enter to reboot device.
Device will boot in system, wait till you can see device on PC and copy ROM on internal SD card once again.
Repeat ROM installation with Aroma installer, do wipe during install.
Congratulations, you have device with fully working Android 4.2.2 and Sense 5.0
The device did boot in system and everything seems to be fine, new android and sense version, ect. I pluged it to PC, copied again the firmware.zip, went to TWRP recovery but the file isn't there. I even placed it inside a folder from root but still the file doesn't apper and that's why I can't continue witht he flashing process even though it seems that there is nothing more to do.
I could leave it like that but what if I want to try another rom some day?
In thephone I see 16 gb of storage, in windows explorer 10 gb more or less. If I mount the folders TWRP lets me, I get a device showing in windows explorer that needs to be formated and it's only 48 mb
What can I do?
thanks a lot!
Hello mate.
I second this.
I am currently having the exact same issue as described here.
I have rooted my phone, superCID, S-OFF, installed MaximusHD, flashed new firmware for MaximusHD and this is where I hit a roadblock.
It began like this:
I went to TWRP, plugged in phone, mounted it (I chose to mount Data in TWRP not SD card, as SD card could not be selected) - system was asking to format the device - I chose no, and moved over the MaximusHD rom (let's call it ROM.zip) using
Code:
adb push ROM.zip /sdcard/ROM.zip
The operation was succesful, TWRP showed the file ROM.zip in /sdcard, however, when I tried flashing it, I couldn't -> the access to SD card was blocked. I followed all the instructions in this thread:
http://forum.xda-developers.com/showthread.php?t=1630459
After this, I went back to TWRP, mounted SD card (this time it was selectable) and pushed ROM.zip onto /sdcard
The operation was succesful, and yet TWRP did not show the file in /sdcard.
Note: System does not ask to format the device anymore, but it shows only 50mb of storage. TWRP also confirms 50mb (47mb, to be exact)
I repeated the process, same result.
I tried to boot into system using TWRP -> reboot -> system, the phone restarts and hangs on HTC One screen.
To try something else, I went into bootloader and locked it using
Code:
fastboot oem lock
The device restarted into system, once again went into HTC One screen but this time, after a couple of seconds began optimizing apps.
A system launched. Weird, considering firmware update supposedly wiped everything off the phone, not even mentioning all the resets and wipes I did by following the thread I posted earlier. I went through first launch steps and was now in a fully functioning MaximusHD system, the one I installed the first time.
The device connected to PC easily and now it showed full storage size, with all the folders and structures inside.
Inside I found two icons which surprised me. They looked like two 0 bytes empty partitions that could not be double clicked or deleted (upon deletion system throws an error that device might have been disconnected). I tried to move ROM.zip onto there, after it finished, instead of ROM.zip now there were three 0 bytes empty partitions. This is when it struck me - my 2 previous attempts to bring ROM.zip onto /sdcard with adb push are those two partitions that were already there. I unplugged and plugged my device back on, the partitions disappeared and ROM.zip showed up.
I went back into recovery and it still showed 50mb storage size and nothing inside SD card (nothing other than two folders, TWRP and .android_secure).
I rebooted the device into system and it hung up on the HTC One screen. I unlocked my bootloader and locked it again using
Code:
fastboot oem lock
and was able to return to system. Somehow, locking my bootloader lets my device get past the HTC One screen. However, the system started fresh again so I lost all the apps that were meanwhile installed (a file manager) and all settings. I went through the process and was back into working system. This is the moment where I am now, confused as to what to do next.
I went into my file manager which I got from Play Store again, which showed the entire folder structure. When I pressed back to go into the root, I was surprised to see that I actually wasn't in /sdcard.
Right now, the exact same folder structure seems to be located in four places on my phone:
/storage/emulated/legacy
/storage/emulated/0
one of these two were on default in the File Manager,
also found one here:
/storage/sdcard0
and also in:
/sdcard
My theory is that the file system in /sdcard gets wiped every time the phone is restarted and somehow brought back fresh onto /sdcard, but it doesn't make much sense and doesn't explain why TWRP shows completely different paths.
I also flashed TWRP to the newest version, to no result.
I fixed my own issue 5 minutes after posting this response...
I skipped the point where you have to install TWRP that is given in the Install Package in RUU mode. This was the root of all problems.
Reflash your firmware, following the instructions here: http://forum.xda-developers.com/showthread.php?p=45621060 (post 68).
What a way to waste 5 hours just because i thought I don't need TWRP because I already had it installed.
Good luck on your issue.

[Q] Can't flash from SD Card

Good evening, XDA :cyclops:
I am having issues flashing from recovery!
Some device info: Motorola Xoom WiFi, fully stock and fully updated, unrooted, bootloader unlocked today, device wiped multiple times. This is my first day trying anything custom on this device.
I decided today that i wanted to go custom on my Xoom today and update it to KitKat via this method.
I have downloaded all the required files per the mentioned guide. While in recovery i go to apply update from USB drive, but it is not finding any of the downloaded files from the guide.
What I see is
Code:
Android system recovery <3e>
Choose a package to install:
/sdcard
../
The ../ is my only option to click and it obviously returns me to the main recovery menu.
All the zip files are on the root of the SD card, not in sub folders. I have confirmed via PC and another phone that the files are indeed there. I tried with a different, fresh, formatted (fat32) SD card, but I'm getting the same results.
The Xoom is indeed reading the SD card, confirmed via settings>storage.
I've tried using adb, but it's telling me the image isn't correct, but it's certainly possible I'm missing a step with adb.
Code:
C:\Xoom bootloader unlocker2>adb reboot bootloader
C:\Xoom bootloader unlocker2>fastboot flash R.A.H._TWRPv2.6.3_BigPart_selinux.zip
unknown partition 'R.A.H._TWRPv2.6.3_BigPart_selinux.zip'
error: cannot determine image filename for 'R.A.H._TWRPv2.6.3_BigPart_selinux.zip'
Yes, the zip is in that folder. I thought maybe I'd root first, so I tried that method with the root zip, but I'm getting the same error.
Is there something I can do to repartition this device and get it rommed, or am I doomed to use it stock?
Thank you for your time!
I found some information stating that I need to enable the SD card, but since I'm running up to date SW, and I can see the SD card from settings, I'm assuming that this isn't the case, correct?
I'm still stuck. Anyone around who could give me some advice?

It appears the XOOM does not like SD Cards that were formatted using Windows
(or perhaps Quick Formatted using Windows).
Using a 4GB FlashDrive formatted as Fat32 using Linux (i.e. Linux Mint 17.3 Cinnamon 64 bit boot CD)
resolved the issue.

[Completed] Asus ZenPad S 8 Bricked. Have CWM. Need ADB RSA Authentication, but can't access OS.

Hello!
I just got an Asus ZenPad 8.0 about 6 hours ago, and now I broke it. I rooted it successfully using this guide, but then I updated the firmware, and now it's bricked. I can probably return it with all of the holiday returns policies, but I'd rather keep it. Anyways, here's the problem, and what I've tried.
I found the script in the link above that lets me access CWM recovery. My plan was to format everything, then copy the zip using adb, and install it through CWM recovery. The script temporarily flashes CWM. I can't find another version of CWM for my device, so this is all I've got to work with (I think). This backfired on me because I also deleted my RSA keys. I never thought I needed them in my recovery, and I've done this pleanty of times on my Nexus 6, without the need for keys when working with my TWRP recovery. TL;DR: I can't copy the factory image zip to my tablet.
Here's what I've tried
-------------------------------------------
Using ADB to copy the file (Doesn't work, need RSA Authorizations)
Find a new recovery, then flash it via fastboot, and then use ADB via that recovery (Couldn't find another recovery. Checked CWM and TWRP pages, but couldn't find my device)
Put the zip on my SD card & extract the zip from the card (Error mounting the card. I used another device to format the sd card. No luck. Tried this article and this article)
Booting into safe mode (Still bricked... still didn't work)
Cursing at it
If I can get past the "Permission Denied" and "unauthorized" stuff with ADB, that would be great! I just don't know how to do that.
Let me know if I'm missing anything and what my options are before I return it in a few days. Cheers!
I figured it out. CWM needed a SD card with a capacity of 32gb or less. Since I was using a 64gb card, I couldn't mount it. I stuck in my 8gb card from my Raspberry Pi, put it in, and now it's mounted. I installed it, and now I just have to wait on that.

[Q] Soft Bricked tab, no custom recovery and no way of selecting USB debugging option

So i soft bricked my device while trying to install the latest 4.0.1 image. I tried hard wiping the device and wipe cache partion from Stock Recovery but didn't help, still wouldn't boot. I tried installing the image in Stock Recovery from Apply Update From External SD Card, but i got a few errors first "E:Failed to map file Operation aborted", i took a look at the file and it had about 1.67gb extra in "Userdata" i tried deleting that file and reinstalling from external sd card but then i got "E:footer is wrong" "E:signature verification failed" Operation Aborted.
Now i'm trying to install update from ADB (Surprisingly if i have the tab connected and im in Apply Update from ADB the tab is recognized in ADB
Code:
adb devices
serial # sideload and i have updated the drivers) But if i try to flash the recovery file 4.0.1 (provided from the developers site [cant post links]) "i just get waiting for device"
Anyone know how to get around this issue in ADB or properly install from external sd card without getting errors?
(Alternative read to my problem posted in the Nvidia Forums 98% sure i soft bricked my device [cant post links]
Did you ever find a fix? I'm having a similar problem.
Try to use fastboot restore everything.
I can't get it to connect to fastboot. When it loads the boot loader and I try to select fastboot protocol it fails.
Wow this thing sucks! I'm really appreciating my Samsung with Odin right now! So I finally got it to connect to fastboot (don't ask me how, I don't know) unlocked the bootloader and flashed twrp. Now it won't flash supersu in adb sideload so I put it on an SD card (which now magically mounts and works now) and flashed the zip in recovery but it says at the very end of the process while trying to update the partitions that it can't mount the data and system partitions so I'm not sure if I'm actually getting root or not and if so if it's permanent I have no way to tell. I think this is because they have been accidentally wiped. Do you think it is safe to try to flash a rom in recovery from external sd card? And if so which one? I have no idea which version bootloader, kernel, or os is or was on this device...
Update: I think I may start a new thread in the Q&A/Help section so that I can try to get a vast concensus. Thanks!

Yes flash a ROM in recovery.
Try Resurrection Remix. It'll resurrect your device
Just tried flashing bliss 6.2 and it won't get past the nvidia screen. It says it flashes successfully but I still get a bunch of "can't mount such and such partition" errors during the flash sequence. Not sure what to do, I can post pics if you guys want.
If you got/can get TWRP on there now, the advanced wipe menu will allow you to check /data for errors. As for /system, wipe it. If you get errors that e2fsck can't fix in your TWRP log, you'll have to put on your data recovery hat on. If it's that important to you, my advice is to adb pull the right file under /dev/block. You won't get a block device, you'll get an exact image of your data partition. Once it's fully pulled (it'll be 10 GB or more on a 16GB device), make a copy of it first thing, and use data recovery tools (testdisk, or if you really know what you're doing, debugfs). If you don't have anything valuable on /data (remember that any backups you took from recovery go in /data/media by default), just format that and be done with it.
Pray that there are no errors after you format everything, because that usually means your NAND is toast.
If your errors are hardware ones, you're royally screwed. Same thing happened to my Nexus 7 2013 model a year ago. Only way to use it is to flash a modified kernel that will use an attached USB drive exclusively as storage. If the NAND is toast inside the boot partiti,try replacing recovery, otherwise, you have to tether boot it (fastboot boot) every time you want to run it, unless you have the guts to try repartitioning the NAND (unlike on PCs, messing up there is an instabrick).
Since the Shield Tablet can use SD cards, you're better off. No USB drive needed.

Micro SD Card no longer recognized issue ....

Ok, I have searched high and low to try and solve this issue without having to post it on the forums. There are several old threads about the Micro SD having issues here, and many many more across the net. At any rate let me start from the beginning.
So, I decided to root my stock tf300t and try the KatKiss 6.0 rom. Micro SD working excellent at this time. I also installed TWRP recovery image 3.0.2.0. Then for some simple reason ( read it somewhere) I dropped back to TWRP 2.5 and Micro SD still working excellent at this time. So, everything is great up to now.
I had found out that I had not formatted to f2fs and somehow with my big hand while doing so on the bootloader screen my pinky brushed the wipe data button. Yep, I lost it all and was stuck in the splash screen or TWRP 2.5 If I booted to recovery. My Micro SD and my TF300T's system files (all of them) showed 0mbs across the board. My file partitions were a mess to say the least. --- I posted about it in another thread.
Finally with the help of forum member gs-crash-24-7 I was able to flash the factory rom back to my TF300T and got my tablet back, with the exception of the fact my Micro SD no longer shows in my Tablet or on my pc when plugged in via the data cable. Now when placed in a card reader on the pc all my files were shown on the MicroSD< so I saved them elsewhere and using SDFormatter did a complete format and complete overwrite. (currently in fat32 mode - but have tried them all) Put a file on it and the pc reads it like a charm.
So, I went installed KatKiss 6.0 again in hopes the MicroSD would magically show up, also installed Kang TWRP 2.8.7.2, pico gapps, and supersu 2.52 to gain root access. But to no avail, I still have a Micro SD card that works great in my Galaxy S5, TF101, and my pc. I tried several different Micro Sd Cards as well, from a 128mb to 8gb one, which is the card I use in the Tf300T.
Ok, throughout my search of the net I found a similar issue that had been solved by adding a few lines of code to their phones permissions/platform.xml file. I have not tried this (honestly it was late and I forgot to bookmark where it was posted. lol Anyway, I did however go into my platform.xml file and did not find very much code in there at all and nothing mentioning External Storage R/RW etc etc ..... so Now I am wondering if I should revert back to JB 4.2.1 and start over in hopes it will restore my files and Micro SD. what are your opinions????? Open to suggestions.
Or if someone who has an Asus TF300T with a custom rom or factory rom (with a working MicroSD, could possibly take a look at their Platform.xml file and see if what is mentioned in it about External Storage etc .... I really feel like something somewhere that got deleted/wiped was not rewritten during the unbricking of my TF300T.
I Thank you in advance for any help or suggestions you may have to offer.
Flash back to stock 4.2.1 JB and still the card does not show up when inserted.
If I add the following lines into my system/etc/permissions/platform.xml file do you think it would bring back the ability to see my External Micro SD?
Code:
<permission name="android.permission.READ_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
</permission>
<permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
<group gid="media_rw" />
</permission>
<permission name="android.permission.ACCESS_ALL_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
<group gid="sdcard_all" />
</permission>
Anyone ever try this?
BTW, my Micro Sd was working just fine in the tablet until the accidental data wipe. I am stuck here, I would really like to get the ability to use the Micro SD card/cards again.
Thank you in advance.

It seems there is an unknown issue remaining after things you have done in the past. Please start your TWRP and "Format /Data". It may take one hour plus. Wait patiently until it finishes. After that your system is clean. So you can clean install the ROM of your choice. Simply follow the install instruction given by Timduru carefully!!! Finally the SD card issue should be solved.
Thanks will give it another try.
Several attempts at this using the latest stock rom and my own twrp backup (from when the sd card was showing up) and still not showing up. Tried to change files system in twrp and got this e:block device not present, cannot wipe ext_sdcard .... only close reference I found so far was in the following thread and according to post #16 my sd card partitions are not correct???
https://forum.xda-developers.com/tr...kang-twrp-tf700t-2-8-x-xarea51-t3049395/page2
also, according to twrp manager:
Storage Info
External SD Location
/Removable/MicroSD
But of course it does not show up in file manager. Thoughts?

This thread deals with Data2SD. That's not your problem. The SD card should be FAT32.
However what's the result of Format /Data? Has it been accomplished successfully? Does your TWRP finally show the external SD card?
No, I have yet to get it to show any SD from 128mb to my 8gb card, I have tried them all. The card is formatted in fat32 (I have tried all formats though). The only time TWRP seems to see it is if I want to fix or change the file system, (now when I was in twrp 3.0.2.0 was the last time it worked) TWRP shows it as vfat. If I try to change it I get the error string below (red text).
All of this started when I corrupted the partitions in the tablet and had to flash a factory rom on to get it going again. Since then no SD card, well actually no SD card while it was corrupted either only before the mess I made.
I feel confident that the SD card issue has something to do with where it's actual path or permission might be placed or written. As the card works excellent in my galaxy s5 and Tf101 and Windows. just not the tf300t. Attached several images maybe one of them will give a clue. Keep in mind under mount, when I choose the Ext SD it just greys out and will not accept a check mark for selection, same when I choose where I want to install a file from.
Again thank you for your help.
Well I have tried going back to the latest stock rom and now I am flashed to the latest KatKiss 7.1, but still no luck. is it possible that somehow when I messed up my file partitions that it, that they just will not clear up completely for some reason? Grasping here I know.
This happened to me and I am still currently dealing with this. I believed that there is a problem with that device recognizing the SD card, as in the card is not making contact with the device. The SD card comes up as corrupted when the ROM is running. I had to side load the last few time through TWRP to get a new ROM flashed because I wiped everything. On this last try I was able to get the device to recolonize the SD card by pushing and hold the SD card all the way in and holding it there for the duration of the flash. I went through all the same as you did including flashing back to stock. Sorry you are dealing with this.
Thanks, I will give that a try also when I load my next rom.

Tried the hold the Micro SD card in deal, didn't work for me.
So now I am currently on a clean install of KatKiss 6.0 with same results. Micro SD card not being recognized.
My install process:
Wiped everything then formatted data
Even fastboot erased everything again just in case via fastboot:
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 reboot bootloader
Flashed KANG TWRP 2.8.7.2
Wiped davlik and cache, then changed data to F2FS file system
Rebooted to Bootloader then entered RCK / KANG TWRP where I did a TWRP BACKUP (it will not backup I know this) so I would have the TWRP folder it would create, so I could load my zips etc, once I was no longer in fastboot. Once in Twrp, you can see internal files then like the TWRP folder, where transferred my zips via the pc to. (now I have a place to load them from)
Loaded the Micro SD just in case with my zip files and also copied them from my pc to the TWRP folder in tablets internal storage.
disconnected from pc and loaded MicroSD into tablet slot.
rebooted into recovery (TWRP still would not load Micro SD ... so plan b) from internal storage via the TWRP folder that was created I flashed all my zip files together:
Flash KatKiss 6.0 rom
Flash the SuperSU 2.52 zip
Flash gapps nano
Wipe cache/dalvik
Reboot
Everything was done per Timduru's instructions, except where I had to load my files via the internal TWRP folder, and I use the Nano gapps over the pico. Also, one tablet reboots to the system i updated the SuperSu Binary.
Some of the Erasing was probably overkill, but I was trying to clean as much as I could in hope my Micro SD would show back up.
Tablet is working fine, in fact very fluid and speedy. I just do not have access to my Micro SD card, except via a usb adapter when used on the pc, which does me no good lol.
At any rate If you do not have a Micro SD card, maybe my process will help someone do a clean install at least.
I hope a solution appears. I just upgraded from cyanogenmod 4.4 to katkiss 6.0 today, and have the same problem . microsd was there for the install, but after booting, ES file explorer doesn't see it. Can see the usb drive plugged into keyboard, but not microsd. frustrating. was thinking of trying to reflash everything but what I am reading in this thread, it seems like that won't help. (btw, there was also issue of tf300 not rooted after install. I reflashed superSU, and after a few reboots and attempted binary updates, suddenly root appeared. I don't know really what fixed it)

What version of TWRP are you running? .... I also had a problem at first with root, but none since and I have flashed every katkiss rom and my back up of JB 4.2.1 and even the fresh stock Asus JB rom with no success as of yet. But I have yet to stop messing with it, going to keep on til I break it, fix it or possibly shoot it. lol
Also, mine still does not work at this time. I actually went online with lj50036 and went through lots of force load commands etc etc and it still never showed up. Crazy thing was at one point it was showing I has 2 Internal Storage folders both with the exact same file size and files within it. I suppose there is a possibility that the card slot stopped functioning in my tablet, but I just keep coming back to my original issue before the card disappeared (corrupted file partitions). I don't know why, but I just feel something somewhere is still fubarred with the file partitions dealing with external storage. Plus with all the research I have done on the issue and such close to it, there seems to be an issue with happening with many devices and custom roms and recovery.
I wish you luck and if I do find a solution I will most definitely post it here.
Issue solved:
Turns out one of the SD Slot connecting pins was broken in the back of the card slot. Oh well, at least it's a 32gb tablet.
Many thanks goes out to Josh lj50036 and the others who tried helping me.
I installed (4 th install, 3 with 6.1) kat kiss naugetella, 7.1. microsd card is now seen. I have no idea what was different about this install other than the 7.1 and different supersu, version 2.79.
still not having keyboard recognized during sleep. previously I could wake the tablet by hitting the keyboard sleep key. No more. have to use the tablet power button.
