started downloading, should take about 20-30 mins. Will report my progress.

After got ROM downloaded, extracted it twice into the folder with ADB & Fastboot (folder C:\Users\Val\Downloads\adt-bundle-windows-x86-20130219\adt-bundle-windows-x86-20130219\sdk\platform-tools on my PC) Connected TF300T to PC. Went into ADB mode, ADB found tablet (adb devices command). Entered adb push blob /sdcard/blob - got flashing cursor forever (waited for 10 mins without results, should it take so long?). Tried to copy META-INF & blob files manually to internal SDcard & continue from adb shell, su & dd if=/sdcard/blob of=/dev/block/mmcblk0p4 - got flashing cursor for same long time. When I entered su, tablet asked for root permissions, I agreed. No other notifications on tablet nor on PC. Something isn't right...

12 mins Later: yes, waiting time in cmd is quite long & we should have great patience. ADB reported that

1601854+1 records in

1601854+1 records out

820149641 bytes transferred in 434.240 secs (1888701 bytes/sec)

Then exit & adb reboot. Tablet rebooted into TWRP again. That was JOP40D.WW_epad-10.6.1.15.3-20130416 firmware, so it didn't work. Now following your advice & downloading ASUS Transformer Pad TF300T Firmware: V10.4.2.20 Only for WW SKU (Android 4.1) & will see if have success. I reached limit of my "thanks" clicks for today. So thank you here!

[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
For info you only needed the blob file and META-INF. It wouldn't hurt anything to copy it also.

META-INF is used by recovery both stock and twrp to know what to do with the blob file or other contents (custom roms).

Are you still automatically going into twrp when you adb reboot bootloader or are you pressing volume up to get there?
[Transformer TF300T Q&A, Help & Troubleshooting] goldenval:
yes, after I downloaded WW_epaduser_10_4_2_20_UpdateLauncher, I unzip it & it becomes WW_epad-user-10.4.2.20 zip file, I unzip it again & get 2 files: META-INF (file folder) & blob file. I place them into folder where adb & fastboot are. Then follow comands, they seemly perfroming, as they should (looking at time delay) & when I give last comand adb reboot it reboots into TWRP. In order to get back into normal Android I have to use adb reboot bootloader comand. When I use it - it reboots into bootloader with 3 icons & from there I click on Android & get into normal android.
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
If you are in the bootloader and don't press any keys do you stay in the bootloader with a message about starting fastboot? I'm trying to find id we can use fastboot.
[Transformer TF300T Q&A, Help & Troubleshooting] goldenval:
I'm trying not to get confused in terminology. When I get rebooted into bootloader (black screen with 3 icons: RCK, Android & Wipe Data - is that one? It also has wtite writing on the left top corner: Key driver not found... Booting OS. Android cardhu-user bootloader <1.00 e> released by "WW_epad-10.6.1.15.3-20130416@ A03. Starting FastbootUSB download protocol) I will stay there for as long as battery lasts. If I click on RCK - I get into TWRP (which doesn't work form me, because it's wrong one), if I click on Android - I get into normal home screen of Android & when I click Wipe Data it says: wiping user data & any indicator before cold-booting Linux. Booting recovery kernel image & boots into TWRP again.
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
Yes that is the bootloader. There is probably a better name but since you can get there by rebooting bootloader that is what I use.

That is good. I had misunderstood. When we get that message about fastboot we should be able to use fastboot flash a proper twrp. Your terminology is at least as good as mine.

We need to download a proper twrp for the 4.2 JB bootloader. I was looking over the current options and one is showing double displays so we'll use the other which everyone says will work. openrecovery-twrp-2.4.4.0-tf300t-4.2.blob should work for us.

Download and place in the directory with fastboot and adb on your pc.

Boot your tablet into the bootloader and leave so it activates fastboot. - ensure you have a good charge on your tablet

fastboot -i 0x0B05 flash recovery openrecovery-twrp-2.4.4.0-tf300t-4.2.blob - once this completes type the next command

fastboot -i 0x0B05 reboot

if either command fails retry but leave out the -i 0x0B05 and try again

I have full battery on the tablet & half battery on the keyboard. I started charging keyboard, while trying to follow new plan on the tablet. Restarted tablet into bootloader (with adb reboot bootloader), got 3 icons with same white writings & flashing RCK icon & nothing else happening. I didn't touch volume buttons at this stage yet.

Tablet got kind of frozen (RCK stopped flashing) & nothing esle happening. So, I'm waiting. Not sure if process is going on right now?
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
Give it a few minutes (10) more and the try

adb reboot bootloader

if that fails try

fastboot -i 0x0B05 reboot-bootloader

If that fails press power and volume down when the screen changes release power.

If you get the bootloader press volume down on RCK.
[Transformer TF300T Q&A, Help & Troubleshooting] goldenval:
waited for 22 minutes with frozen (bootloader) screen & got your reply. tried your suggestions, got next:

So, I pressed power & Volume- & got it completely powered down. But because it was still connected with USB, it powered up itself (while I kept volume- pressed) & loaded into TWRP.

repeated everything from the start. downloaded openrecovery-twrp-2.4.4.0-tf300t-4.2.blob & didn't rename it this time (rename it last time into twrp.blob), left full name of the file. Then:

and tablet is hanging again. I'm wonderring why flashing process took so short time (5.087 sec)? or is it normal?
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
Can you tell if this is the same twrp you had previously?

If so or you can't tell try to get back into fastboot mode.

Use fastboot to flash the blob file in your fastboot folder.

fastboot -i 0x0B05 flash system blob

fastboot -i 0x0B05 reboot

It will take several minutes ten or more.
[Transformer TF300T Q&A, Help & Troubleshooting] goldenval:
No, originally I downloaded wrong (for me) openrecovery-twrp-2.5.0.0-tf300tg-JB.blob , that's where my problem started. And recently you suggested to try openrecovery-twrp-2.4.4.0-tf300t-4.2.blob hoping that this would fix recovery. So, I'm trying to flash most recent file 2.4.4.0

Doing what you said:

so far:

>fastboot -i 0x0B05 flash system blob

but reboot on the tablet itself didn't happen. I had to long press power & rebooted into TWRP again. Dear tobdaryl I appreciate your great help, but will you excuse me for tonight. I'm in Ireland & we have 1:35 midnight. I'll continue on tomorrow sometimes. At this stage tablet doesn't boot even into android for some reason. Just hanging on bootloader screen... and now PC sees my tablet in Device Manager as MTP USB device with yellow ! sign...
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
Ok, tomorrow.
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
goldenval

When I asked about whether you could tell about which twrp you had I should have asked differently.

I knew what version you had previously flashed. I wanted to know if with your recent flash it twrp had changed or did it remain the same as before that flash.

I need to bring something to your attention.

The twrp I asked you to flash had 4.2 in the name to designate to be used with the 4.2 bootloader.

The twrp 2.5 4.2 version has given many people problems so I suggested the 2.4 4.2 version as it works.

The twrp you chose to flash (2.4.4.0) has no such number meaning it is for the 4.1 bootloader.

Do not try to flash anything with this twrp.

We will have to start getting information about your tablets present status before we begin again.

After being powered off your tablet may have changed.

Will your tablet boot into android?

Do you have adb access?

Do you have fastboot access?

Can you get into twrp?
[Transformer TF300T Q&A, Help & Troubleshooting] goldenval:
yes, let's summarize. Currently tablet can be booted with normal power on action only into TWRP. When in TWRP it shows v2.5.0.0 version & that TWRP doesn't work. PC reads tablet as Asus Eee Pad Slider ADB interface.

adb reads tablet as

List of devices attached

0123456789ABCDEF recovery

I can reboot tablet into bootloader with adb reboot bootloader.

When rebooted I 'm in the black screen with white writings on the top left ( Key driver not found... Booting OS. Android cardhu-user bootloader <1.00 e> released by "WW_epad-10.6.1.15.3-20130416@ A03. Starting FastbootUSB download protocol ) & 3 icons in the centre: RCK, Android & wipe data.

If I click on RCK - I get into same TWRP

If I click on Android - tablet freezes & PC finds new device MTP USB device. It trys to find drivers for it from windows but can't & tablet remains frozen. I have to long press power in order to power it down.

If I click on wipe data - it says wiping user data & any indicator before cold-booting Linux. Booting recovery kernel image & boots into TWRP again.

When I said "click" - it isn't right, of course I select action with volume- & confirm it with volume+

That's where I'm at the moment...
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
Since the tablet will no longer boot into android flash your stock blob with fastboot again.
[Transformer TF300T Q&A, Help & Troubleshooting] goldenval:
sorry, flash your stock blob means flash stock rom? just to be sure...
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
Yes, sorry.

Just as you did yesterday.

Flash the stock rom blob with fastboot.

fastboot -i 0x0B05 flash system blob

fastboot -i 0x0B05 reboot

if either command fails try without the -i 0x0B05

fastboot flash system blob

fastboot reboot

We are trying this again because your post shows you flashed twrp to your system partition instead of recovery which killed android.
[Transformer TF300T Q&A, Help & Troubleshooting] goldenval:
Little more clarifications before I start. Remember, I've already flashed system (message #35) & reported to you. And after that I lost my Android. So, do we want to repeat same flash?
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
We are at the end of what we can do with your tablet. There are no more things to try that I am aware of except flash 10.4.2.20 as I previously suggested.

We need a break to recover this tablet and we haven't gotten one. Nothing we have done has made a positive impact.

I have managed to help several recover from very similar situations but more have failed than ended with success.

The situation you began with is considered a hard brick when on 4.2 stock rom.

Don't forget the second command if you get your blob flashed and your reboot command fails.

fastboot reboot

In some circumstances your tablet is not aware it is Asus (-i 0x0B05) and fails. We want to get the system to reboot if possible.

Good Luck!
[Transformer TF300T Q&A, Help & Troubleshooting] goldenval:
Please don't take offence. I do appreciate your help & I understand that you might be more busy then just talking to myself, therefore I remind you what have or haven't I done. Yes, let's try to use all possible chances. Currently I have tablet on charge & will wait for atleast half the battery before start flashing. As usual, will report you my progress, THANKS AGAIN!
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
I take on offense. I just felt it was time to let you know how dire your situation is. I haven't quit but we are certainly getting close to the end of what we can do without a positive sign. Taking an active role in recovery is good as is asking questions.
[Transformer TF300T Q&A, Help & Troubleshooting] goldenval:
I'll go through all possible steps & I'm trying to be optimistic. But (knocking wood) in worst case what'd be a option? Buying a second hand mother board? Or trying to sell mine for parts trying to get as close as possible money to what I've spent about a half-year ago (about 250 euro) when bought it?
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
There has been good success with used motherboards. There have been a few horror stories with used motherboards as well. I have read many more positive reports than negative. I would look for an add stating from a cracked screen tablet.

I'm sorry I can't give a better answer. You need to research the market in your country.

How about an update!
[Transformer TF300T Q&A, Help & Troubleshooting] goldenval:
Hi. Yes, tried with & without 0x0b05 - no success. It reports that so many seconds spent, so many records in & out (don't remember exact text), then tried reboot with 0x0b05 & without. It says rebooting... finished in X seconds, but tablet doesn't reboot, so command isn't going towards it. If I reboot it manualy with power button - no TWRP nor new ROM are found installed (tried them both, just in case), so I assuming even when it's reporting that ROM is written - it's not happenning...

Had to take pause for today-tomorrow, as I'm originally from russia & we have Easter this weekend. Will come back here after tuesday or so, sorry. Thank you for taking care!

Sorry, are you asking me? I can't use adb any longer. PC doesn't see the tablet as android, it sees it only as asus fastbot & I can only apply fastboot comands. Looks like android gone on my tablet.

I think this may be something else. Can you tell me anything else about the tablet?
[Transformer TF300T Q&A, Help & Troubleshooting] matt95:
tell me what you need... i installed the wrong twrp with the 4.2 bootloader and now i'm bricked too
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
I need to know what access you have to your tablet.

First when you turn your tablet on what happens?

Do you have access to twrp, stock recovery, adb, fastboot, bootloader, and can you get into android?

Have you flashed any other roms since this problem? If so what bootloader do you have?

Note: Your partitions are (probably)being emulated elsewhere for encryption purposes in 4.2. I can't prove this at the moment since I'm not on 4.2, maybe later.
[Transformer TF300T Q&A, Help & Troubleshooting] matt95:
i can use adb since i can access to TWRP 2.4.4.0 and also fastboot with the latest 4.2 bootloader... i can't boot into android
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
First I need to tell you my replies may be slow but I have not abandoned your problem.

My suggestion is download the 4.2 firmware with the proper sku for your country. Unzip twice and place the blob file in the directory with adb and fastboot.

fastboot -i 0x0B05 flash system blob

fastboot -i 0x0B05 reboot

When complete tell me the condition of your tablet again.

If the commands are refused then modify them and try again.

fastboot flash system blob

fastboot reboot

If the flash completes and reboot fails only change the reboot command.

This will be slow.

[Transformer TF300T Q&A, Help & Troubleshooting] Insane PPC:
just FYI for this thread, i'll run anything you want (but i will be sending my tablet off soon for warranty...)

right now i have the latest 10.6.x bootloader, not sure which step i screwed up at, either loading a wrong recovery or kernel. not sure...

but for a few days i was able to get into the rom, but not into recovery, (unrecoverable bootloader)

after some more messing around blindly, now i still have fastboot access (until i try to flash/write to the device)

so i've tried to write just a bootloader (stock bootloader.bin) i've tried to do different recovery (twrp 2.4 and 2.5 and stock) i've tried to erase different partitions inbetween flash's and installs...

anything else you would want?
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
I have to first tell you I may be slow to respond. I now have exams and two work-at-home jobs.

Is the usb symbol missing from the bootloader you now have (4.2 bootloader)?

Can you get into twrp - we should have access to adb if you can? We might need adb later.

When you power on your device what happens? Go to bootloader, go to twrp, etc?

It is likely I will ask you to flash the same thing multiple times. This tablet is odd. When a flash fails it may still rewrite boot or bootloader or recovery and fail everything else. Once we get boot, bootloader and recovery to the same version we can probably fix your tablet. This method is very trying but is the only thing I have found to recover from the wrong twrp for the bootloader. At each step we will look for any change in your tablet and decide what to do next.
[Transformer TF300T Q&A, Help & Troubleshooting] Insane PPC:
no worries on being slow, i know how busy life can get!

thanks for taking the time, your support on here is awesome.

yes there isn't a usb symbol. it goes straight to fastboot. if i try to get into rck it just gives me the 0x000000 unrecoverable bootloader.

when i turn on the device all i get is asus logo and nothing else, i can volume down to get into fastboot, but so far the only thing it allows is to send simple commands, flashing only seems to lock up the fastboot on the tablet and then i have to reset/hard power the tablet off
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
Try this command

fastboot -i 0x0B05 reboot-bootloader

If that fails then try

fastboot reboot-bootloader

The -i 0x0B05 is just a designation for Asus and your tablet may not realize it is Asus with the changes previously made.

If this one works we know to adapt our commands till we make some progress.

Sometimes this command helps establish the proper boot sequence. We probably can't expect to get into android since you have done some wipes but it may help with processing a flash.
[Transformer TF300T Q&A, Help & Troubleshooting] goldenval:
I'm in same boat as Insane PPC. When I try to boot into recovery (TWRP) it gives me red writing 0x000000 unrecoverable bootloader. And exactly same thing with normal booting: when i turn on the device all i get is asus logo and nothing else. So, after whatever I did recently (nothing different from what we disccussed) it looks like I lost TWRP now & only can get into bootloader menu now. Tomorrow will try above reboot commands again, will report with success. You were saying about light in the end...?
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
It appears you are rid of twrp. That should be a plus. I think Insane PPC still has twrp, otherwise the same.

I believe with twrp out of the way we may get a stock blob to flash; at least a partial flash. We'll even take a partial flash as that would be a step ahead.
[Transformer TF300T Q&A, Help & Troubleshooting] Insane PPC:
i doubt i have twrp anymore, yesterday i went through and tried the erase recovery command...

also if i'm working on my ubuntu laptop i don't need the -i 0x0b05 when doing fastboot commands, while on my windows box it does need it. and fastboot reboot-bootloader does infact reboot and puts me right back to the fastboot screen on the tablet
