I recently purchased a TF201 tablet and keyboard on ebay. I was mainly after the keyboard to replace one whose battery refused to charge. I already knew the tablet was bricked and it was essentially free, but took it to see if it was recoverable. I now think it is hard bricked but thought I would check here to confirm
It will boot to APX mode (can see it in devices on PC) but that doesn't help because I do not have a blob.bin for the tablet.
When it boots up normally, it displays the Eee Pad splash screen, and up the top it says AndroidRoot 9.4.2.28r01. This is displayed for a few seconds, then the screen goes blank and it reboots again. It does this continually in a loop.
If I hold down the Vol - button while it goes through a reboot, it displays the same as above, but also
"
Android cardhu-user bootloader <2.10 e> released by "WW_epad-9.4.2.28-20120525" A03
Checking for android ota recovery
Booting recovery kernel image
"
once again, this is displayed for a few seconds, and then the tablet just reboots again in a loop
I have tried the reset button as well, but that didnt help
Any ideas?
So they flashed the androidroot bootloader but don't have blob.bin?
You need to go flash a ICS-era recovery somehow. (Ask them for the blob.bin or hope that your fastboot is working)

Dear community,
I tried to boot into CWM (installed via Rom Manager) but nothing happend after the reboot-to-recovery, invoked via Rom Manager. The tablet was stuck at boot, displaying the Asus logo. No animations and no error messages were displayed. I needed to press and hold power to reset my prime so it would boot my rom again. I was still able to load fastboot (power + volume down)
Next I tried to reboot-to-recovery using Goo Manager. The same issue occurred, stuck at startup, displaying the Asus logo, but now I am unable to recover from that state to load the rom!. When resetting my prime it is still stuck at displaying the Asus logo. No animations and no error message displayed. I can also no longer enter the menu using power+volume down...
I am afraid I perma-bricked my Prime but ofcourse hope it is not the case. Can anybody help me confirming my fear?
Thank you for helping me out!

That is bricked unfortunately.
CWM only ever worked on the ICS bootloader and there are warning everywhere on here never to use it.
You needed the correct version of TWRP for what bootloader you was on.
If you cannot get into the rom, the bootloader menu or you have nvflash backups that you created before then you are out of luck.
Hi flumpster, Thanks for clearing this up :good:
I think I have the similar problem. I have TF201 Android 4.1.2 installed and a PC Ubuntu 13.04 installed.
-First of all, I used unlocker releases by Asus. Then I loaded CWM by fastboot, but it didn't launch, I loaded CWM Touch, but it didn't launch, I loaded TWRP and again it didn't launch. When I tried to launch recovery rom every time it stuck at splashscreen.(It says booting recovery rom or smth like that)
-Then I tried to start unlocker again, it gave network error.(If you shut down the wifi it asks for internet, I think Asus collecting some information about prime.)
-Then I rooted my device. Again it stuck at splashscreen while trying to launch recovery rom. I reloaded recovery roms again it didn't work. I choose restart to recovery from the ROM MANAGER, it stuck again but nothing about "booting recovery rom" just "device is unlocked" writen. Then finally I installed CWM from ROM Manager again and I choose restart to recovery from GOO Manager. Boom! I think it tries to boot recovery rom in everytime. I can't boot android, I can't boot fastboot, power+volume down didn't work. Even I can't close it, it always restarts and I had to wait until the battery last.
So is there anything to do?
I've had my Prime unlocked since I got it, I recently put on TWRP but kept the 4.1.1 OS stock rooted. Last night it was running slow, so I did a Data Wipe from the TWRP recovery screen. Now whenever I start it, it hangs on the ASUS splashscreen and does not boot. Holding the volume down and power button does not allow me to boot into recovery and my computer does not recognize it if I try to plug it in. This post sounds a lot like it, but I don't see a solution to it here. Thank you for any help!
Device turns on, goes to ASUS logo screen with 'The Device is UnLocked." in corner. Can't enter recovery, can't enter fastboot.
Device can only go into APX mode, and I have no nvflash blobs previously.
Am I surely hard bricked? Is sending this in to ASUS the only option at this point? (Because I have 0% experience with hardware, taking this tablet apart, replacing hardware in it, etc.)
Thank you

hi, i have a problem with my asus zenfone 5 (root), I think it's in hard brick, I explain better, yesterday I did a restore to "clean" the system, while restoring freezes, then I try to boot into recovery mode, I long ago I installed a custom recovery, the fact is that by inserting the recovery.img and trying to start it from the custom recovery I get errors and does not install, so start in droidboot mode to adjust all manulamente by pc (GNU / linux), with fastboot flash the recovery.img, but when I have to do the last step described by driving mistake, now I do not have a chance to get more in recovery mode, in fact, when I press power + vol + appears the Android logo with red exclamation point, if I try to start it normally there is a loading of the asus logo with the infinite wheel, but when there is asus adb logo detects it, it just says chen is not "authorized", the phone has to be thrown away? There are hardware / software solutions?
thank you so much
ps: sorry for the grammar are not English

Afternoon
I have a Lenovo 7" tablet which is sticking on boot...to describe:
tablet off, charge screen working fine (green battery)
can get into menu to select fastboot mode or recovery
fastboot works, at least screen appears!
recovery shows dead android/no command screen - how to access recovery?
booting up, get inital orange logo then a 'bing' and start of boot but then freezes on the second logo
tablet not visible on PC, even in fastboot mode (have installed drivers)
I'm looking to get this going but am a bit stumped. I tried reinstalling firmware but can't get SPF Tools to work with any available scatter files; I would like to install TWRP (I found a potential image file on XDA) but can't do this until the PC recognises it....and I'm going round in circles now....any suggestions gratefully received. :good:
Update
OK, post was maybe a bit premature - I've kinda fixed my issues.
Managed to get into recovery after watching many videos (most of which were wrong, but hey-ho, got me on the right path!). At dead android screen, press and hold in power + vol up + vol down together (there is a bit of knack, turn it on its side with buttons facing up seems to be easiest) - this fires up the recovery screen (android standard recovery).
I managed to get over my bootloop issue by performing a data wipe/factory reset and cache wipe, then restarted fine.
As this was a secondhand tablet (my usual purchases - good condition bootloops!) - once it booted up I got into the set-up screens only to discover a Google lock issue. I ran the FRP unlock from here: https://androidfilehost.com/?fid=11050483647474832839 using the instructions from here: http://forum.gsmhosting.com/vbb/f958/lenovo-tab-4-7-essential-tb4-7304f-frp-remove-2322527/ (Voltrans second post, not the original one which has a 404 error on the download site). This removed the FRP lock straight off and now I have a functioning tablet.
I'm probably going to try getting custom recovery on so will see how that goes - I'll post back
and...that's all folks....
OK, despite finding a TWRP recovery online https://twrpbuilder.github.io/downloads/twrp/#441 and downloading it, can I get the fastboot unlocked? no.
Apparently Lenovo locked them all up and threw away the key, so nothing more can be done here.
I tried various iterations of fastboot oem unlock and fastboot flashing unlock, and nothing works, just get an error - and yes, I did put developer options on, OEM unlocking ticked and USB debugging active.... :silly:
So, unless someone can point me in a direction on how to unlock it - I've reached the end of the road with this one
