For those who may be flashing ROMs, cannot mount the SD Card any more, and may have accidentally corrupted their SD Card, here are some helpful steps.
Preliminary Review - Check to see if you can mount in recovery or bootloader
First, go back to your bootloader screen and click on fastboot (reset your phone and hold the power and vol down button). Once in bootloader check your computer drives to see if the sd card is recognized
Your computer may be able to recognize the drive even if it cant open it. If thats the case, you may be able to format it from your computer (use FAT32 formatting).
Second, If you cannot see your SD Card in your ROM or from the PC, and you are using Clockwork Recovery (CW), try flashing TWRP recovery first. Do this by going through the following steps:
Step #1
Download TWRP recovery from http://teamw.in/project/twrp2/100 Make sure to download the correct version for your device
Step #2
Place the recovery file into a folder with fastboot.exe
Step #3
Reboot your phone and hold down the Vol Down Button and Power Button until your bootloader screen appears, then enter fastboot. Then connect to your computer. I find this method works best by holding down the buttons right away. If your phone is off, press the power button then immediately press and hold the power and vol off buttons again until bootloader screen shows up. Dont let go until the screen shows.
Step #4
Type
Code:
fastboot flash recovery twrp.img
but replace the twrp.img wording with the exact name of your downloaded TWRP recovery
Step #5
Enter TWRP recovery by selecting it from your bootloader screen. Then ensure the device is connected to your computer and select the Mount option and then mount your sd card.
IF you still cant see your SD Card from TWRP recovery or you get an error, proceed to the next steps. Your computer may be able to recognize the drive, even if it cant open it (if your lucky).
If your computer recognizes the drive but cant open it, you can try formatting it from your computer (make sure to format as FAT32)
If you really cant see your SD Card, and your fairly sure its corrupted, and you have no way formatting it from your computer, continue on below:
Basic Solution
Reflashing Stock Recovery to your device using fasboot, then doing a full factory reset. This would be using the method in post http://forum.xda-developers.com/showthread.php?t=1630459
PLEASE NOTE THIS METHOD WILL WIPE THE DATA FROM YOUR DEVICE AS WELL AS FROM YOUR SD CARD
This method works because custom recoveries cannot re format SD Cards on the HTC One S, only wipe data from them. However, the stock recovery does have a proprietary feature that will reformat the internal sd card if it has been corrupted.
Inotherwords:
Step #1
Download the stock recovery from: http://loadbalancing.modaco.com/download.php?file=ville_recovery_signed.img
*******Note that this file is a stock recovery for S4 devices, not S3.
Place the file into the same folder as your fastboot.exe
Step #2
On your device, go into bootloader and fastboot mode, connect your computer to the device, and type
Code:
fastboot flash recovery ville_recovery_signed.img
Step #3
Reboot into the bootloader and then choose to "clear storage" from the main screen and afterwards reset to factory defaults.
Step #4
Go back into the bootloader once step #3 is done and enter fastboot, connect your device and reflash your original custom recovery again. Your SD Card should be visible
Advanced Solution - If you do not want to wipe the data from your device
This method does not require reflashing the original recovery and factory reseting the whole phone. However, it still means that the info on your sd card will be lost. It also needs a rooted device.
This method does not require you to access your bootloader or use fastboot. You can do this while having your phone in custom recovery.
DO NOT ATTEMPT UNLESS YOU FEEL COMFORTABLE WITH THE INSTRUCTIONS. THERE ARE ALWAYS RISKS WITH FORMATTING. DO NOT HOLD ME RESPONSIBLE FOR BRICKED DEVICES. YOUR DEVICE IS LIKELY OUTSIDE OF WARRANTY ALREADY SINCE YOU WOULD HAVE UNLOCKED THE BOOTLOADER.
I have taken this solution from HTC One X forums namely from post 17 at http://forum.xda-developers.com/showthread.php?t=1647806&page=2
However, I have also confirmed (SneakyGhost's partition list for HTC One S) that the correct mmcblk0p for the HTC One S sd card is mmcblk0p36.
Step #1: Download the version of busybox listed below, unzip it and also put this in the folder with ADB before you get started. You only need to do this if you dont already have busybox installed on your HTC One S. Sometimes this busybox file can be found under /system/bin or /system/xbin if youve previously installed it. If so, replace the paths in the instructions below for that of your busybox. If you have busy box already installed in /system/bin , then you do not need to type in the paths since the adb shell automatically picks up programs in that folder
Step #2: Go to your command prompt in the folder with adb.exe . Connect your HTC One S to your computer and type
Code:
adb devices
and ensure your computer sees your HTC One S. This command should work even if you are in a custom recovery like TWRP or CW (but for gods sake, if your on CW, the first thing you should do is flash TWRP, but thats just an editorial opinion, lol).
Step #3: Type
Code:
adb push busybox /data/local/tmp
This pushes busybox to a temp folder on your HTC One S. Make sure you are pushing the busybox file and not the zip file. If you already have busy box installed you do not need to do this step. (you can delete it from this folder later if you like)
Step #4: Type
Code:
adb shell
to get into your linux shell. Then type
Code:
su
to get root access. Your command prompt should now be a # and not $.
Step #5: Type
Code:
chmod 755 /data/local/tmp/busybox
to fix permissions for busybox. You may not need to do this if you already have busy box installed with the correct permissions. If these instructions dont work with your version of busy box, try setting the permissions with this code but replace the path with the location of your busybox.
Step #6: Type
Code:
cat /proc/partitions
and just ensure you see mmcblk0p36. This is the sdcard partition for HTC One S
Step #7:Type
Code:
/data/local/tmp/busybox mkfs.vfat /dev/block/mmcblk0p36
Make sure you type this correctly. You dont want to format the wrong partition accidentally.
That should work. Pls let me know if it doesnt. If it doesnt work with your version of busybox just try using the one in the zip file below. Also remember, dont just push the zip file. Extract the busybox file from the zip and push that to your device instead.
Also, it may help to use adb through a custom recovery instead of being in your ROM (ie if it doesnt work when your phone is booted normally, try doing the steps with recovery loaded).
There are other methods to try too They would be:
Other Solutions
Other Method #1: Relocking your bootloader and using a compatible RUU with your phone. This will fully wipe your device
Other Method #2: If your computer sees your sdcard even if it cant open it when your device is connected, you can try formatting it that way (ie the way you would format any other drive on your computer)
Only use the busybox method if you are comfortable with it and if other methods have failed. You can learn more about the formatting command (ie mkfs.vfat) by googling it.
So if I got this right if I have busybox already I only have to do is step 7.
Almost, but yes, that is the key step. Although you would still want to open a terminal Window, either an adb shell or from the phone, and type su to get root, and double check to ensure the shell sees the partition. Also, I did hear in the one X forums that not every version of busy box worked. I would imagine an updated version would likely work though.

Step 4, a quicker way: adb shell su , get you into shell as root right away

Nice update. Ya I wish they hurry up with sorting it, the other one is a load of crap and this really should replace it.
Updated with a link to another good tutorial about pushing ROMs to the phone
Its like they don't care about stickys any more, come mods its about time this replaced the crappy one.

Does your bootloaderscreen say "fastboot usb" anywhere? There is an option that you have to select in your bootloader called fastboot... If it says fastboot usb then you are connected, and you shouldnt get a waiting for device error.

yea I got into the bootloader and then fast boot. ive managed to sort it now, for some reason my pc was the problem, I had to reboot my computer after a command window prompt otherwise I just got the waiting for device screen.
typical really, my laptop and phone both conspiring against me.
eventually managed to flash another recovery which did see my sdcard so all is good now.
thanks for your reply though!

Could someone please help me with this? I have posted a thread over on Android Forums with all the problems.

Also, I have posted on here in the past about this, but I honestly am a giant noob at android and did not know what they were telling me to do.
Any help would be really great, thanks!
Since you can still boot your OS, you should be in good shape.
Try installing GooManager from the Play Store.
After installed, open it and grant root permissions.
Next, tap the menu key in the top right (3 stacked boxes) and then choose the Install OpenRecovery Script. This will install TWRP recovery which is far superior to any CWM I have ever run.
See if that installs properly (if yes, you will end up in TWRP recovery during a reboot)
TWRP allows you to see the internal and external memory to flash new ROMs.

I will try this out when I get home. Thank you. I will report back with what happens.
Edit: Also congratulations on 100 thanks.
format your micro SD and only put the ROM you want in it. Now install twrp as other guy said and reboot into twrp recovery in go to wipe and wipe (dalvik, cache, internal memory, system and everything else expect micro SD). Then do a clean installation of ROM and you should be good to go.. if that doesn't work then try easy flash

This did not work, I still boot into cwm when the device restarts after downloading it.
Here is another thing to try:
If you can boot and want to try TWRP, here is another way to install it so long as you are rooted:
Download the 2.3.2.3 blob from HERE
Place the recovery blob in the /sdcard/ directory. We are going to pretend the downloaded file is called TWRP.blob
Open a terminal window and enter these commands
Code:
su
cd /sdcard/
ls
dd if=TWRP.blob of=/dev/block/mmcblk0p4
reboot recovery
the ls will tell you if the blob is indead where it is supposed to be, if it can be seen, you should be good to go on to the dd command, if you don't see the file, do not procede.
Make sure to change TWRP.blob to the actual name and location of the file you downloaded
Let me know how it goes

I cannot connect the device to my computer at all. I have usb debugging enabled and everything. It freezes for a couple of seconds when I plug the device in, and then says that installing the drivers has failed in windows. I am trying to run adb and it says no devices are connected.

You don't need to do this on your PC, so long as you can boot you can do it on your tablet.

Ah, sorry, long time since I've done this. Alright, well I've gotten into terminal emulator and I've typed that exactly, switching over my directory to my microsd though and changing the file name to the exact one. I'm getting a "cannot open for read: No such file or directory" error when I do this. I have also tried moving the file to /sdcard/ and I have named the file twrp.blob, and neither of these have helped.
Did you issue the su command and get a popup for root access?

Yes, that was the first thing I did. I did exactly as you said. I've tried changing file names, changing directories and everything but for some odd reason I'm getting the same error.
Edit: and yes, I'm changing those when I enter them in terminal as well.

Try a normal reboot at the end instead of reboot recovery and see if that works.
If not, run through this and download one of the flashable .zip files (it is version 2.2.X.X) and see if that works. If so, then run through GooManager to get the 2.3.2.3.
This is how i fix my TF300TG stuck on recovery. I hope the steps descried below will help.
Long story, short:
For some reasons, seems like the WIPE command from TWRP and CWM recovery screw the partitions.
No partitions or microSD card can be mounted.
The tablet is now booting only in recovery mode or in fastboot mode (the screen with three icons - RTK, Android and WIPE) instead of Android.
IMPORTANT:
If your tablet reboot in fastboot mode DONT WIPE IT AGAIN! Just skip step 4.
First of all, MAKE SURE YOR BATTERY IS CHARGED!
Recharge your tablet for at least two hours.During the flashing process the tablet doesn`t charge.
Use the original Asus USB cable that came with the tablet or a high quality replacement cable. Cheap cables can and will cause problems.
Use a laptop or desktop with known good USB ports. If you have problems, try a diferent computer, some USB chips can cause troubles.
Disable the antivirus or screensaver, sleep etc...
1.Download these files:
from ASUS website: http://www.asus.com/Tablets_Mobile/ASUS_Transformer_Pad_TF300TG/#support
Drivers&Tools, on the OS tab select Android
click on Utilities and download latest version of ASUS PC Sync (you will need this for drivers)
click on Firmware and download the lastest available (you will need this for BLOB file)
Minimal ADB and Fastboot: http://d-h.st/gbx
install ASUS PC Sync and Minimal ADB and Fastboot (on fastboot installer check the box that make a shortcut to desktop)
unzip the firmware file downloaded from ASUS site
you will get a second zip file, unzip this one too
the folder unzipped from the second one contain a file called blob
copy or move the folder to the root of your drive C: or D: or whatever drive letter you have
2.Installing drivers:
connect your tablet to PC
you will get a message about Windows couldnt find driver bla...bla, ignore it and keep your tablet plugged
IMPORTANT: even if you previously installed ASUS PC Sync or other drivers and Windows recognize your tablet, you still need to change the driver.
right-click on My Computer-Properties and click Device Manager
find the Asus Android device - should be with an exclamation mark on it (the driver is not installed sign)
right-click on it and choose:
Update Driver Software..., Browse my computer for driver software, Let me pick from a list of device drivers on my computer, Have disk, Browse
go to C:\Program Files or Program Files (x86), ASUS, ASUS Android USB Drivers, Android and select android_winusb.inf
Asus Android Composite ADB interface will appear in the list of device drivers - don`t hit next yet!
uncheck Show Compatible Hardware and select Asus Android Bootloader Interface from the list, now hit next
3.ADB mode:
open Minimal ADB and Fastboot from desktop - from this point, keep it open
type: adb devices - and you should see some numbers under the List of device attached - thats your tablet
if you can`t see the tablet, try this command: adb start-server
4.Booting to "fastboot":
there are two ways to do this:
a) from adb window type: adb reboot bootloader
or
b) reset and hold vol-down (didn`t work for me, but maybe will work for someone else)
the three icons will appear on screen - NOW YOU ARE IN FASTBOOT MODE
if none of the above work try this:
in adb window type: adb reboot
wait until the tablet enter in recovery menu and type in adb window:
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3
adb reboot bootloader
5. Flasing the blob
the credits for this part goes to buster99. He is the one who figured out the right commands for formatting partitions and flashing back the OS
here is his post: http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
here we go, one at the time in adb window:
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 flash system x:\your blob folder\blob (here you enter the path to your blob file, must end with blob, to point at the file)
fastboot -i 0x0B05 reboot
THE FLASH SYSTEM COMMAND WILL TAKE SOME TIME
be pacient and wait until the progress bar is 100% full on the tablet and you get the command prompt back in the adb window.
After reboot, the Android is back on.
Cheers and good luck!!
A big thank you alexhosu,
several months ago that my tablet was blocked, but I still kept hope
a solution would be found. I'm really happy for you and thank you again for sharing.
Long live XDA
me too
Thanks from me too; was enjoying 5.0 (timduru) on my TF300 when I went to upgrade and idiotically managed to get into a TWRP bootloop(interrupted a format of \data and then used 'wipe' from the boot screen by mistake...)
Your solution has saved my tablet
Am now carefully reinstalling Katkiss
Thanks
This saved my (veggie) bacon too, something went wrong when flashing new ROM (most likely user error - e.g. my fault). Tablet woud go into an eternal boot wouldn't finish booting, nandroid recovery did the same. Used this technique and have a working stock ROM from which I intend to reinstall TimDuru's Lollipop.
Thanks again
Followed the instructions.. Worked well, but getting error 963 when installing/updating anything in Play Store. Seems to be related to storage permissions. Some users are suggesting using format instead of erase. What's the difference? Could that help.
I did factory reset, reflashed and used fix permissions in TWRP but no luck...

Big thanks from me.
I killed my tablet with an accidental restore to factory defaults while in cm12, an got stuck in an endless bootloader boot loop.
my tablet came back too life at the end of section 4 after adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3.
although getting adb to talk to the tablet was a fluke.
I just kept trying to send "adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3" while the tablet was loading (boot looping)
6 months of believing my tablet was dead, after letting CM12 do its own update thing, and now, thanks to the above instructions, I'm back online and its working with the stock rom.
Thank you so much for this. No idea why I couldn't find these instructions before, then I just gave up, back in business now!
Thanks a lot for your guide, this is what helped me fortunately unbrick my device, i was stuck in a boot loop with a broken recovery
Another tablet saved. Know your work is appreciated.
i have the same problem, the system doesn't pass the ASUS logo, i tired to log into fastboot (reset + volume down) and i was able to see the three icons but adb doesn't recognize my device. i see the drivers are correctly installed but no working adb. Any help is highly appreciated.

Did you try entering "fastboot devices" or just "adb devices"? adb wont find your device in the bootloader, but using fastboot commands should unless it truly is not connecting for some reason.

I would try moving the blob to the root of the C drive and try the 7th command "fastboot -i 0x0B05 flash system C:\blob" just to make sure sometime of file permission type issue isn't happening on the pc side. Other than that the only kind of issue I think it could be would have to be the connection with the drivers, although if erasing the partition's works fine, I don't really see what could be going on.
I followed all the steps and delete, but when loading the file update.blob I get this error:
C: \ Users \ mikel> C: \ Users \ mikel \ Android \ android-sdk \ platform-tools \ fastboot flash system update.blob
error: can not load 'update.blob'
Can someone help me out?

Hey, I know that I'm a couple years late on this. But, I was just given a Asus Transformer TF300T, and attempted to install the Kisskat custom rom. I unlocked the device with little issues. Rooted with little issues. But when it came to flashing the rom. I get his error saying that "no MD5 file found" and holds it there for a couple of minutes. Then gives me the failed install. My only option is to boot into recovery and restore the stock JB 4.2. If you could point me in the right direction, I would greatly appreciate it. I've searched the forum for someone with a similar issue, and couldn't find it. I hope that I'm not alone on this one. It would kill me to be stuck with the stock rom.
Hi i made a format data from TWRP recovery, and now i am in a recovery loop and got error of mount partitions, i can access to recovery and the screen with 3 icons, but when i plug to my pc it shows as uknown usb, i install the drivers but dosent reconose as a fastboot device, in minimal adb when i write fastboot devices the result is empty pleace help me.
Muito obrigado!
I know this must seem odd, being such an old thread and all but, after several years adding apps and changing ROMs on my wife's TF300T (my gift!) only these past weeks I had the need to search for help, after installing nougatella 7.1, which I did with success, only to stumble on endless logo loops and loading processes without conclusion. Don't get me wrong, the ROM looks great and it wasn't that hard to install but, after two weeks or so, gave me this problem and after correcting it and installing again the ROM, I got in trouble again...
After some five hours googling and trying different stuff, I finally found this thread and twenty minutes ago (around 2:AM) my ASUS returned to its (Jellybean) life!
Alexhosu, thank you so very much for such a detailed, yet easy to follow guide and, if you happen to come to Portugal on vacation and visit Setúbal, I'll have a bottle of Moscatel waiting for you!
Many thanks to Droidbound (who got me off the hook the first time the tablet went nuts!), and also Kevinthefixer, Gtanner00 and some other very inteligent, patient and thoughtful people, and all the guys who shared their difficulties and in a way helped me find the people with the fix.
For anyone interested in trying this method, I would say that it's paramount that you should stick exactly with what is asked and should pay real atention to what is the correct ROM update to download and use. If anyone needs help with translation to Portuguese, just say so.
Again, thank you so much for this!

This is how i fix my TF300TG stuck on recovery. I hope the steps descried below will help.
if none of the above work try this:
in adb window type: adb reboot
wait until the tablet enter in recovery menu and type in adb window:
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3
adb reboot bootloader

Thanks for your help :good: and I'm sorry for my basic English, but here is another tablet saved. Your instructions were clear and my tablet is working.
I hope this information helps, based in the next link (user sszyman): https://forum.xda-developers.com/showthread.php?t=2275035&page=9
in which he recommends using the following commands too:
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p2
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p8
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p1
With these commands and "adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3" I was able to solve my Bootloop problem.
Honestly I don't know which of the commands worked, I used all several times.
Hello people,
First of all, I'm not an expert so pardon on that.
I had a MicroSD card in my tablet and it was partitioned using GParted, 2 partitons - fat32 and ext4. I erased the whole tablet with Wipe option in TWRP and installed move2sd.zip.
Anyway... When I pressed Reboot to recovery, tablet restared, showed TWRP and screen went on and off showing TWRP logo, like it was trying to load TWRP. Now... Since I installed that .zip file it might have written some code to use MicroSD card as boot? I reinstalled TWRP by flashing it via fastboot and was able to enter TWRP again.
Now the stupid part... Since it read 0mb on internal card (tablet), I wanted to fix it by formating Data... It didnt do the trick cause /data and other folders couldn't have been found. That's where I restarted the tablet and pressed Wipe data on the screen with 3 icons (RCK, Android, Wipe data)... Since then I only see 2 screens - bootup screen with Asus logo and message: Device is unlock and the next screen is TWRP and it flickers again, goes on and off just as if it was trying to load TWRP.
I cannot reflash recovery cause there is no fastboot?
I just hope this is not an expensive paper...

You can still enter RCK ??
Not that this helps your situation, so apologies.
Just started getting the screen flicker/lines randomly when handeling it. So my guess was just the loosining of something internally.
I`m also freecarding it. So that hadden`t crossed my mind.
Time for a tear down vid I guess.
Best of luck tho.
I'll make a quick video. Be right back to you...
Edit: I cannot post a video due to XDA rules, but you can search for it: TF700 no fastboot, recovery stuck (search for recent uploads, d jakolis is my username on YouTube) If you guys cannot find it, I can email the link to you.
As you can see in the video, there is not much left to do with the tablet.
However, when I selected Wipe Data on bootloader, did it wipe kernel too? I'm asking this cause I had installed data2sd.zip along with its corresponding kernel.
What would happen if someone else with the same device installed the custom ROM on MicroSD card and handed me his MicroSD card to pop in my tablet? Would it boot off it? Would I be able to enter Android and maybe somehow re-flash recovery and stock kernel along with stock ROM?
You should still be able to connect via adb. Try adb pull /tmp/recovery.log and adb logcat.

Looks like your /data partition is not formatted properly. Try this (don't type "#" and the following comment):
Code:
adb shell # connect to a shell on the device
killall -19 recovery # suspend the recovery so that it doesn't interfere with formatting
make_ext4fs /dev/block/mmcblk0p8 # format /data
dd if=/dev/zero of=/dev/block/mmcblk0p3 bs=64 count=1 # remove "wipe data" request
reboot
Wow... I don't know what to say. I'm looking at the fastboot screen! :highfive:
I didn't type the last line of your code because it rebooted itself after format data was complete - make_ext4fs... Is there any consequence for not typing the last line?
Alright, I'm in recovery right now. Question: What is installed on the tablet right now? If anything... May I proceed with installing stock ROM and maybe do nvflash process to have an unbrickable device?
P.S. What does it take to learn all these things? I'm curious cause I like coding, so if you feel happy to share it, I'm all ears.

Maybe the "killall -19" stuff didn't work and the recovery was not suspended, so it may have somehow determined that the wipe was finished and initiated a reboot.

What is installed? Whatever recovery, kernel and ROM you installed last. No other apps since you just formatted /data.
Since the nvflash (flatline) process saves only BCT, bootloader, partition table and unlock token (basically all the stuff you need to get fastboot working on a hard bricked tablet), you can do that now.

If you can still enter recovery (which one do you have?) you can use the build in Terminal.
Otherwise you have to get the adb drivers installed and working. There is no other way if you do not have a working recover and cannot get into fastboot.
Try this tool: http://forum.xda-developers.com/showthread.php?t=2588979
Once you get the drivers installed boot the tablet to recovery and post what you get with this command:
Code:
adb devices

Copy and paste it into your cmd window
sorry but it says dd is not inside or outsite command and bla bla i cant translate directly but like this
is not recognized as an internal or external command, operable program or batch file

Splendid!
Now - did you a full wipe in TWRP before installing the rom? Select the Wipe option and swipe the button. Then re-install the rom.
On the last page of the Aroma installer you have the option of saving the installation log. Do it.
Then back to TWRP, go to Advanced and also save the recovery log.
If the ROM still doesn't boot, post both of those logs.
Also try to capture a logcat of the boot process
Code:
adb logcat -v long > logcat.txt
Post that one too.
Dear All,
I own a Asus EeePad Transformer TF101 tablet. I have accidentally bricked my tablet (wiped out the Android operating system) whilst attempted to upgrade to Android 4.4.
I have contacted various IT Repair services, but they have been unable to repair the tablet. It is regrettable that the tablet cannot currently be repaired because it is a lovely machine.
Please could you let me know if there are any Android experts who can help me? Your support is much appreciated.
Best,
Stephen Tang

Ok so there might be a problem with the sdcard reader or maybe with the recovery. But anyway you should be able to use adb to push a rom to your transformer when booted in recovery mode.

I've tried Easyflasher and other things but no luck. The recovery won't mount the SD card.
I haven't tried adb - apparently it's very complicated to do and I'm not exactly the most technically gifted person!

Even easier you could use adb to push the newest twrp and use the built-in MTP function so you could see your tablet as a Storage device on windows, then drag and drop a rom to your internal storage and flash it.
So make sure you have all you drivers installed for the tf101 on your computer
download and install "minimal adb and fastboot"
download twrp 2.8.1.1 and save it in the same folder where you have installed minimal adb and fastboot"
Boot your phone in CWM recovery
In the folder where you have installed minimal adb and fastboot, hold left SHIFT and right click a blank space in that folder, select "open a command prompt here".
in the command prompt, type:
Code:
adb devices
you should see an output like this
Code:
List of devices attached
(your tf101 serial number) recovery
If yes then proceed with the next step, if no, post back here.
in the command prompt, type this:
Code:
adb push signed_twrp-2.8.1.1_tf101.zip /sdcard
and wait for the output, something like
Code:
1330 KB/s (5215688 bytes in 3.828s)
then in cwm, select "install zip from sdcard" and navigate to find "signed_twrp-2.8.1.1_tf101.zip" and install it.
then power off your tablet and reboot in recovery mode again, but this time you should boot in TWRP 2.8.1.1
when booted in recovery (TWRP) You should see your tablet as a storage device in windows, so all you need to do from there is to drag n drop a rom like this one to your device in windows and install it using twrp.

My IT repair people tried your instructions and they said that the tablet won't accept the any of the instructions. Do you have any other ideas?

Well all you need to do is to push a rom to your tablet using adb, which should be done when booted in recovery mode. Don't even need to use an sdcard. I don't have any other ideas except finding another IT or a friend that know how to use ADB. Or you could send it to me but im near Montreal so I don't think it will worth it vs shipping cost.
Btw im using this method to flash roms on my gf's transformer without issue (the sd card port is damaged so I can't use sd cards)
Thanks for the prompt response. So the Repair Man should follow through steps 1-7. What happens at Step 8? Is this where he would push a ROM to the tablet using ADB - instead of using CWM?
