Completely Stock Bootloop - Asus Transformer TF700

My son's TF700T is completely stock and the bootloader is still locked. The tablet gets stuck while booting at the "shiny" Asus screen. I can access the Fastboot screen, but that's about it.
With a locked bootloader, are there any options?

You have two options:
Wipe Data from the bootloader or reflash the Asus firmware.
To wipe data, just select that icon in the bootloader menu with Volume Down, then push Volume Up.
To flash the firmware in stock recovery read this: http://www.transformerforums.com/fo...e-firmware-tf700-tf701-tf300-tf101-tf201.html

Wiping the data had no effect, but re-flashing the firmware worked like a charm.
Thank you!

Bricked

My TF300 is unlocked. I installed the new JB and then I was trying to install CWM. I used fastboot to push it to the device. When I rebooted, holding down the volume button, It came up to the menu with RCK, USB, etc. I selected wipe data by accident. It sat there for a while saying it was going to wipe and go into the boot loader. After a while I shut it off thinking it was hung. Now when I power on the device I get only the ASUS startup screen. Volume up or down don't affect the mode. It just says "The Device is Unlocked" at the top, and the static ASUS logo in the middle. When I plug in the USB to my Windows 7 computer I get nothing in the device listing. I can't even fully turn the device off. Holding power for a few seconds, it goes off, and then it comes right back on by itself.
I think I'm totally bricked, right? I CAN get into APX mode.
Yes, wiping the data will brick your device if you don't have a working recovery.

Actually, I just discovered that I do have access to APX. Is there a way to push a working recovery through APX?

I did exactly the same thing.
I have exact same problem.
Tried it via APX mode via NVflash but no luck so far.:crying:
need the correct SBK version.
SBKv1 and SBKv2 doesn't work for the TF300t.
I send my tf300t for repair.
Lets hope that they can fix my TF300t.

Unfortunately, APX and nvflash is not available for the TF300T currently. As I understand it, you're required to record some information and your Secure Boot Keys (SBK) prior to bricking to be able to access APX. Otherwise, your only recourse is to contact Asus and start the RMA process.
I'm recording my developments over in this thread : http://forum.xda-developers.com/showthread.php?t=1825265&page=2 (my post is at the bottom)
I think I'm going to hold out until someone figures out the NvFlash process as described here:

I had the same issue. wiped my data after the JB update as my device froze halfway through the update, so I forced a reboot and it hang at the Asus screen, so not thinking I wiped data to go do a fresh update... I wiped the update and all my data/system/recovery.
I found that in the boot loader screen (Wipe Data, Fastboot, ETC....) I was able to navigate to fastboot select it and then it would hang from there. - my computer wouldnt recognize it either however, i tried flashing a copy of TWRP anyway while in my hanging fastboot just to see what happened.
It didnt work first few times but it did eventually flash. so I had a recovery to work with. via a MicroSD put a fresh copy of the JB update on it and re-flash through the recovery via External SD Card.
It did remove my root access, TWRP and all the data on my device after flashing the JB update but it "un-bricked" me and got me booted again.
Don't know if I was just lucky or if it will work for you.

The difference in your situation is that you were able to access the boot loader. My boot loader is wiped. I don't get the option to select Wipe Data/Fastboot, etc. I'm stuck in a mode where I think the only option is to low-level flash the bootloader after re-initializing all of the partitions.
Happened to me too. I'm hoping that ASUS will fix it for a reasonable price. Otherwise I'm just going to get a Nexus 7.

[Q] Help w/Twrp Install

I'm in a bootloop mentally and technically! I've spent days trying to install Twrp, searching the forum, watching videos... Think I've tried most guides two or three times w/o success. From GooManager/Install OpenRecoveryScript it starts downloading and then aborts w/a "false MD5 blob" pop-up. When I tried to install directly I had a validated MD5.
This is not a very helpful description of the problem but I'm so brain-drained that I really can't recall all the different things I've tried. Amazed I've not bricked the thing! Am just hoping someone can point me in the right direction.
TF700T, v.4.0.3, Kernel 2.6.39.4.
I just checked the posts "suggested" last night when I posted in the wrong form and I've been to them all except the one about using motochopper to root and then using GooManager to install Twrp recovery. I'm already rooted. Should I unroot and reroot w/motochopper?

Is your bootloader unlocked? See http://teamw.in/project/twrp2/105 "You need to be bootloader unlocked to use custom recoveries."

If you don't see"This device is unlocked" top left when you boot, you are not unlocked and cannot install a custom recovery

taaz69, having the same problem I had b/4 following the "Recovery Image/Fastboot Method" on the link you furnished:
When I boot into fastboot (power on volume down) the only options that appear are two icons, "Wipe Data" and "Android". There is no usb icon to select.
Following "ADB/Terminal method" with terminal emulator or with adb it seems to be doing something, but I still cannot boot into the bootloader...same two "Wipe Data" and "Android" icons.

You can download the Asus Unlock app V8 from Asus website.. You need to install it on your device and open it. It will walk you through the whole process. It is very quick and easy.. Good luck. :fingers-crossed:

Yeah, like LetMeKnow said, you have to unlock your tab using the Asus Unlock tool.
The info on the TWRP site is somewhat outdated and refers to the JB 4.1 bootloader. Under JB 4.2,
if you boot into the bootloader menu, you are already in fastboot mode by default. Under 4.1 you would select the USB icon to start fastboot. Oh, btw, if you boot with Power and Volme Down, you ARE in the bootloader...
I do hope you have RCK in addition to the Android and Wipe Data in your bootlaoder menu! Otherwise something is seriously wrong here!
Once you unlocked you will be able to use GooManager or the ADB method to flash TWRP.

IIRC the old 9.4.x bootloader used some other way to boot to recovery.
@cBirdR: if your firmware version is still 9.4.5.26 or earlier, be sure to read the thread about NVFlash *before* you install anything and create your blobs for unbricking.

The 9.4.x bootloader was alsmost the same as the new bootloader, the only difference is that it had 4 options (fastboot, recovery, coldboot and wipe data) instead of 3.And iirc if the device was locked the fastboot option (USB icon) was hidden but the recovery was always there (RCK icon).

Forestalling further ****ups, Asus says V8 is for 4.2 JB. I'm still on 4.0.3 ICS. Shouldn't I be using the V7 Unlock Device App?

@cBirdR: Did you see _that's post? Stop what you are doing and check your firmware version! If you have .26 or earlier, you are in a very enviable position! You cannot use NVflash on later firmware versions.
Think long and hard about letting this opportunity pass.....

Yes, read _that's post, but my build is 9.4.5.30 so thought did not apply to me. Closed the window I had open on NVflash. Are you saying I should not use the Asus apk?

No you are ok. Your one build too late to enjoy an unbrickable tablet
Go ahead, use the tool to unlock and proceed as planned.

Well, I've finally got Twrp installed, but cannot reboot into recovery from GooMgr or Clock Mode, only via the bootloader. I was re-reading you guys' posts and your #7 says it all. No RCK. I tried downloading it with Clock Mod, indicated success but nothing changed.
Twrp's Reboot Menu only lists System and Power Off, no Recovery or Bootloader option. But Clock Mode Recovery says current recovery is TWRP. Is it time for me to head for the Twrp forum? I know it's time to donate.

I have not used Goo and CM. Therefore, I don't know what they have on their boot menu. About the TWRP reboot menu, there are only two options. One is System and other is Power Off.. If you want to boot into the bootloader, you need to use the power button + volume down when your device is in the off state. Also, if you have the latest bootloader, you should see three icons: RCK, Android, and Wipe..

Let me make sure I understand you correctly:
You have TWRP installed and can boot into it - correct?
Which version of TWRP?
I have no idea what Clock Mod is and I wouldn't use GooManager for anything but installing TWRP.
As _that said, the ICS bootloader may have had a different way to boot into recovery, I don't know - I did not have ICS on this tab ever. But if you can boot into TWRP (hopefully version 2.5, 2.6 will do in a pinch) it does not matter.
If all that is true, select 'Backup' in TWRP and make a nandroid of your current setup. And I assume you have backed up all personal data, pictures, videos etc to an external SD card anyway.....
Assuming you want to run a custom rom, go to the OP of the CROMi-X thread, download and flash the 10.6.1.14.8 bootloader/TWRP 2.5 package and then boot back into system which should happen automatically, but if it doesn't, just boot back into system once.
Boot back into TWRP, select 'Wipe' and swipe the button to do a factory reset. This is crucial. You do not want to install a JB 4.2.1 based rom without doing a factory reset first.
Go back to the Home page in TWRP, select 'Install', navigate to the CROMi-X 4.7 rom you downloaded to your external card and flash it.

berndblb: Cannot boot into TWRP from GooMgr. Pauses a bit on the Asus logo then boots normally. Only method to boot into TWRP is power off, boot w/ boot with Power and Volume Down, b/4 the three icons Wipe, USB, Android appear, push power down and it boots into TWRP (version 2.6.0.0). Not going to try the second part of your post re OP of CROMi-X thread until I see what you have to say this.
ClockworkMod (ROM Manager), koushikdutta developer. I'm sure you know it.

TWRP on my Nexus7 has four choices under the Reboot Menu: System, Power Off, Recovery and Bootloader. TWRP on TF700T only System and Power Off. Also there is no RCK icon when
I did get a backup last night using TWRP.
I've used Quick boot for years and cannot boot into recovery thru it...same result as when try to reboot into recovery w/GooMgr.
Appreciation to you all.

It is odd. RCK is a part of your bootloader. If it is not there, then something is wrong with your bootloader. It just my understanding about the bootloader. I am wrong so many times about the Android OS. So please don't take it seriously until some experts confirm it.. If you screw up your bootloader, I don't think there are many options for you to fix it. Now you still can access to it. I would suggest that you do a factory reset and download the full latest firmware from Asus website and update your bootloader.. It just my opinion. I am very sure some experts here will chime in and give you a better instructions or guides.. Good luck.

Help, unable to get back to recovery.

So I'm selling my TF700 and decided to reset everything. I made the mistake of wiping the data. When I rebooted from TWRP I now get stuck at the boot screen (white asus logo that says unlocked). It will not let me boot into recovery, the options aren't there. Any idea on how I can get back to recovery?

[Q] Nexus 5 bricked?

Hi,
Running stock lollipop 5.0.1 on my nexus 5 - boot loader unlocked, no root been like this since 5.0.1 was released. No recent software changes.
Today my nexus turned off itself and now will only show the Google boot screen (white text /lock at the bottom). I can boot into the fast boot recovery (holding down power and volume) but when I click to enter recovery mode I just get a blank screen and nothing happens.
Thought maybe flashing the stock image would fix this but I have no usb access when I connect to my Mac and not recognised in adb command.
Any ideas or solutions would be appreciated if even to reset the tamper flag and lock boot loader to get a warranty replacement.
Thanks.
Looks like you might have had a bad flash.
If all else fails, your saving grace is that you can still get into fastboot. Do you have a customer recovery installed?
If not, install TWRP or CWM and that should get you to a state to backup your data. Even better, you might be able to troubleshoot further.
And if that still doesn't work, you can always flash the factory image from fastboot.
Good Luck!

[Q] Is my internal storage damaged?

My Nexus 5 suddenly stopped working. It was on stock. Never experimented anything.
Now it doesn't boot. always stuck in boot animation.
Tried to wipe data/ factory reset in stock recovery, but it never completes. after 2-3 minutes screen start to blink. same to wipe cache. Red Exclamation Android logo continuously appears and disappears.
Tried unlocking bootloader, shows success, but doesn't boot.
and, if i again go to fastboot mode, bootloader is again locked.
So, is my storage really damaged?

That's a bad sign. Sound like you are correct in your assessment.
