Just follow Buster99's procedure then flash recovery and custom ROM... That's all.

Flash blob file only if you want stock ROM

I have your same problem , then you have solved .

Thank you.
[Transformer TF300T Q&A, Help & Troubleshooting] Malobestino:
I solved like everyone else did using the Buster99 procedure, i.e.:

Bear in mind that depending on your setup erasing userdata can take a while. For me it took over 30 minutes.

Don't panic, DON'T RESET your device

Just wait till is over.

As TheGrinder77 suggested I didn't flashed the blob, but instead I flashed the recovery

And then flashed the new ROM (that I previously put on a microSD card) from inside recovery.

Still I have I minor issue.

From whitin recovery if I choose reboot to system it take make back to recovery over and over again. I have to turn off the device and then turn it on in order to access to system.
[Transformer TF300T Q&A, Help & Troubleshooting] berndblb:
... which leads me to believe you flashed TWRP 2.8.6. That behaviour is a known bug. Flash 2.8.7 or lj's Kang TWRP
[Transformer TF300T Q&A, Help & Troubleshooting] Malobestino:
I checked and the number displayed in recovery it's 2.8.7.0.

I also verified the md5 of the file i flashed and it corresponds to 2.8.7.0 one.

I don't know what is wrong with my tablet, but as long this is the only problem, I'm good with it
[Transformer TF300T Q&A, Help & Troubleshooting] kozmo2k4:
For the folks that end up "loosing" recovery (in my instance I used TWRP 2.8.5.0, not CWM), and can't get the Recovery to boot to, but system (CM 11 in my instance) boots fine.

Get your TF300T to Fastboot and try this as mentioned in posts above, with the addition of ERASING MISC PARTITION:

Quote:

>fastboot -i 0x0B05 erase cache

erasing 'cache'...

>fastboot -i 0x0B05 erase misc

erasing 'misc'...

>fastboot -i 0x0B05 erase recovery

erasing 'recovery'...

>fastboot -i 0x0B05 flash recovery twrp.img (or twrp.blob)

sending 'recovery' ...

OKAY

writing 'recovery'...

OKAY

finished. total time: x.xxs

>fastboot -i 0x0B05 reboot

rebooting...

finished. total time: 5.001s

As soon as the Recovery is "sent", you should see a progress bar under the three icons.

Upon a full reboot, go ahead and try to Reboot Recovery and see if it work. It did for me.

I was trying to update TWRP from 2.8.5.0 to the latest (listed on their site) 2.8.7.0 from within the recovery, and after a couple of reboots, I lost acces to recovery.

I have tried many of times as mentioned in the posts above in this thread to get recovery back, but without formatting the MISC partition it did not work.

Hope this helps someone in the same situation.

I have the same problem(that's I update the TWRP recovery 2.8.4.0 to 2.8.7.0 from within recovery itself ,loosing to boot in recovery mode).I want to ask you if you have used a Buster99 mode or you reflashed only the TWRP recovery?Thank's

All I did wast boot into bootloader ("#adb reboot bootlaoder") and executed the following:

>fastboot -i 0x0B05 erase cache
>fastboot -i 0x0B05 erase misc
>fastboot -i 0x0B05 erase recovery
>fastboot -i 0x0B05 flash recovery twrp.img
>fastboot -i 0x0B05 reboot

I did not do any wipes, except after a full system reboot, I got back to recovery, to verify it does work, and then wiped cache and dalvik cache. But no system or data wipes.

Hope that helps...
[Transformer TF300T Q&A, Help & Troubleshooting] enzenz67:
Then you used the adb for entering in bootloader and after fastboot For reflashing recovery.....is it right?Thank's

That's correct.

[Transformer TF300T Q&A, Help & Troubleshooting] Buster99:
to clarify something - you only need to flash the blob if you flashed a wrong recovery or a recoveryscript went haywire. in both cases the blob fixes partitionerrors. If you think your partiton is ok just erase misc (where files are kept that can block installs for whatever reasen...) and flash the correct recovery and boot into it and flash CM or whatever.

cheers
[Transformer TF300T Q&A, Help & Troubleshooting] enzenz67:
I've solved in this way( I can enter in bootloader yet):

1)I flashed file blob TWRP by fastboot

2)Then I flashed a new ROM by TWRP recovery.

So I use again my tablet.

Tab unresponsive after doing this procedure

Hi Buster, my tablet does everything as it should but it does not want to reboot. Through all this the "RCK" button flashes on the tablet's screen but as soon as I flash the blob it stops flashing and is unresponsive thereafter. The flashing seems to work completely though, it takes about the same time as yours. Any ideas? I hope you respond... you posted this in 2013 and we're now in 215 :)
[Transformer TF300T Q&A, Help & Troubleshooting] Buster99:
hey

whats the output on your fastboot window from your pc?

cheers

Buster
[Transformer TF300T Q&A, Help & Troubleshooting] ThinusvanAs:
Hi Buster, the output is very much in line with what you've experienced and listed above,maybe slightly quicker. I've seen "unbricking" videos online that have one-click solutions using "win" or nvflash or easyflasher. But I cannot find that for the TF300TG. Any ideas? Thanks!
[Transformer TF300T Q&A, Help & Troubleshooting] Buster99:
nvflash only works if you did it with your own tablet, you can not use another tablets files for that.

Try:

Erase everything

flash only recovery

check if you can boot into recovery

if yes: copy cm12.1 zip on it whil in recovery (adb push zipfile /sdcard/ )

if no:

erase everything one by one (reboot after each erase)

after you erased misc (erase it last) directly flash recovery or blob and check then

good luck

Buster
[Transformer TF300T Q&A, Help & Troubleshooting] ThinusvanAs:
Hi Buster, just to make sure I understand you correctly:

1. My tablet is not rooted and the bootloader has not been unlocked.

2. I can boot into recovery (power button+volume button) which is the standard bootloader, not anything else (like CWM, etc. as the bootloader has not been unlocked). Here I can see RCK, Android and Wipe options.

3. When I use the fastboot flash method you've proposed everything works OK but the blinking light on the RCK icon on the tablet stops blinking and the reboot command does not work--I have to restart the tablet manually.

4. The main problem with my tablet is the "Encryption Unsuccessful" error when I boot into Android, and this happens even after I've done what you've proposed.

Can you please give me more information (links, etc.) on how to do the following:

1. "Flash only recovery"

2. Where can I get CM12.1.zip? When I get my hands on cm12.1.zip I must then use ADB to copy it onto the tablet and then reboot, correct?

Thanks for your patience with me--I'm new at this :)

[Transformer TF300T Q&A, Help & Troubleshooting] berndblb:
This is the same 300TG I tried to help you with on the Transformer forums, right? Your user name looks awfully familiar ;)

As I explained to you there: The locked bootloader will not let you flash a custom recovery - it just can't be done. And without it you cannot flash a rom...

But maybe [MENTION=3127371]Buster99[/MENTION] has a new idea 'cause I'm all out.

To complete the picture: ThinusvanAs has successfully flashed the stock firmware in stock recovery but the "encryption unsuccessful" error persists.

After trying to format /data to f2fs using different TWRPs and also trying to wipe with cm recovery (thread), I somehow messed up the partition table. Official twrp-2.8.7.0-tf300t.img starts, but the block device for data has disappeared:

Disk /dev/block/mmcblk0 doesn't contain a valid partition table

_that already told me, that the partition table is non-standard by default and using fdisk to create a new one would only brick it.

How can I fix it?

I recently did an incorrect format in twrp and totally botched my tf300t...had it for a long time and flashed many times, so not a newbie.

I hit hard times...thought it was a goner as I couldn't get at things.

This reset got me there on fastboot for writing.

I was smart (and fortunate) enough to write the version off the first screen during the fail and was able to flash different blobs until I got a match. Once I did it was a full nuke.

In fastboot & adb (with dameon running) I went thru the list formatting...first great...second gave me a fail. Crap...retry and retry...reboots along the way to reestablish communication between the devices.

Your post kept me in the game as you stated it took like 10 times to get it.

It was a total pain...but now I have backups again.

Thank you so much for this post. Now I feel I can get at it and not be stressing so much.

Cromi has proved to be the best performer for me...sure hope they come up with a new model for this unit. It' till a good one.

Still kept root the whole time too. That didn't hurt my feelings, but was wondering why.

It must not have been a complete nuke, but it sure worked.

I am a bit afraid to apply you method, as i am not sure if things get worse ...

Did you had similar issues in cwm before you applied your method?

As i were not able to access my sdcard i was not able to get root access. Do you have root access and/or will this be required to apply you method?

[Transformer TF300T Q&A, Help & Troubleshooting] Buster99:
yeah baby yeah :D

back to topic:

glad to hear it and took me a while to realize this too - but its kinda logical step by step - since its unlocked even with a brocken PIT it should be recoverable with the original blob (since you can flash all partitions with it) - only thing is to get it to work which sometimes means steps have to beredone 2-15 times for whatever reason or cable issue or usb chipset issue with your pc. thats why i reverted back to win7 (also win 8 sucks) but especially fastboot stuff is fishy with win8 (full admin mode per local sec policy)

and for kreutpet question: try cwm or twrp - i prefer twrp 2.5. get.cm go to tf300 and download the latest nightly and goo.im gapps package (tho i prefer to modify that so that it only installs playstore) and flash it like any other rom

install - add zip - flash - reboot recovery - install - flash gapps - reboot recovery - wipe cahce / dalvik - reboot system: done :highfive:

cheers

EDIT:

with twrp the autoupdate from cyanogen works - never tested it with cwm, though

and yeah, i still don't know excatly why /misc is interfering with successfully flashing /system but I'm too lazy with the weather we have here to investigate - and erase /misc saved my A700 as well - so I learned my lesson (on the A700 i coulnd't even flash recovery - after erase /misc twrp worked and i could flash CM in twrp and everything was fine)

I wanna add for those who've just recovered their devices, the ONLY recovery that hasn't sent me back through this whirlwind of crap is twrp 2.4 found here: http://techerrata.com/file/twrp2/tf3...f300t-4.2.blob

Also, all you guys who were helped by Buster, give a "Thanks".
[Transformer TF300T Q&A, Help & Troubleshooting] Buster99:
thanks!

and TWRP2.4 gave me an error, twrp 2.6 gave me enter password on start (and with that is unusable, cause you can't mount any partitions) so if you are having issues after a brick try diffrent versions and keep in mind - there are JB and ICS builds of TWRP - but don't worry if you flashed the wrong one (like i did late at night :D) it just wont boot into recovery - just do:

fastboot erase /recovery

fastboot reboot-bootloader

fastboot flash recovery "theotherrecoverythatshouldwork" :)

fastboot reboot

and hold your keys to enter recovery

Well is there any official guideline out there which describes flashing custom ROM without ending up that boot loop mess.?

Would be very thank full to get a good recommendation
[Transformer TF300T Q&A, Help & Troubleshooting] Buster99:
Hey,

well it's like with all Custom Roms. download your desired rom and gapps and put both on your sd card. if you on stock make sure to backup on your pc or Titanium Backup/helium. boot into recovery - first do a nandroid (backup) then do a full wipe in twrp (factory reset) and delete system. go to install and then like before:

install -> add custom rom zip - flash - reboot recovery - install -> flash gapps - reboot system: done

hope it helps - but basically if you check youtube - all android tutorials for flashing Cyanogen Mod should apply here as well even if they are for a different device
