Hello XDA community !
LAst week I bought my Acer A700, but after a few days a dead pixel appeared...
So I was on my way to send back my toy, when I saw that CMWR was available.
"Nice ! I can do a factory reset so my toy will be clean to be sent back !"
But the factory reset didn't work... It was stuck at "Formatting /data" for a while...
So I rebooted the A700, and now it's stuck at the ACER logo... I only have access to recovery...
Any ideas ?
Thanks a lot :good:
Since you have recovery try and do data wipe, then wipe cache then davlik cache, then reboot.
If you have recovery you can install a ROM by renaming it update.zip and using CWM.

I already tried this, when I want to install a update.zip, it stucks at "installing update".
When I want to wipe a partition, it stucks at "formating /xxx" and nothing happens...
I wanted to flash stock bootloader with Nvflash, but I can't find APX drivers for ACER A700
Can you install the update.zip without the use of CWM (By pressing the powerbutton with the vol down)?
Also, where is your update.zip located?
Edit:
I guess it could do no harm if you'd hook up your device to the PC and enter the following commands:
adb reboot bootloader
fastboot erase cache

_ update.zip putted on a extrenal SD card doesn't work, it's skipped and CWM is launched.
_ the "adb reboot bootloader" puts the A700 in "APX" mode... and the "fastboot erase cache" is stuck at "waiting for device"...
Thanks for trying to help !!!
May this be a relevant solution??

Edit:
I don't think the device checks for update.zip on the sdcard. Maybe there is a way to move the file to the internal. (adb mount sdcard adb push /sdcard/update.zip update.zip ?
Yeah,
The current CWM seems to corrupt the Data partition (amongst other things). Seems to be a going thing lately. Remember, these are new tabs, and new root & recovery methods, so there are going to be some bricked tabs before things get sorted out. This happens in "ALL" development, and everybody knows the risks involved.
I had the same issue. Couldn't reboot into fastboot, as it seems the OS has to be running?
This is why Skirlax_CZ built the bootloader for the 500/501, so you could boot it into fastboot mode, bypassing the OS. Unfortunately, the stock 70x OEM bootloader doesn't seem to allow this.
Best bet if you can't find the "exact" version rom the tab was shipped with, is to try renaming some full roms to update.zip, copy to sd, reboot (vol + and PWR, and see if it will install and boot. At the worst, it will install a stock bootloader and recovery.
Also, holding PWR, Vol - (I believe) and toggling the rotation lock should wipe User Data.
At the very worse, turn it into Acer Service, suck it up and pay the repair bill.
They will just install the correct service rom and give it back to you.

your situation is just same as mine,seeming bricked after using fatory rest or wiping from cwm,I think it's the problem of the damn cwm.as i know from now there are several devices got bricked,all because of the goddamn cwm.as we know factory rest is the same as recovery wiping,i use the under the official recovery,everything wen fine,but after wiping via cwm from the forum,it appeared the problem.
i tried a lot of method,just as u mentioned,to flash *.img
but i found a curious thing,after dumping series of *.img from a well-mailfuntioning device i can use fastboot to flash "userdata" which the loaction is mmcblk010 or /dev/block/platform/sdhci-tegra.3/by-name/UDA,but after flashing,i can't erase userdata block in fastboot.then i reflashing the data.img to userdata block,then in cwm,i can mount /data,but it's still not able to wipe or format it.then i've found a data.img and flashing the userdata and reboot.then i enter the system,and it forced me to do a factory reset,of course as before,it's not mailfunctioning because of the cwm or the block itself damaged..
but i can enter adb,and i found that i can see the /data and the filesystem in it.then i use mount to modify it,for i can delete or modify the files in /data,and it appears normally.i delete everything in /data.then i want to try to reboot to see if it's working,but after rebooting,the device stuck at acer logo,then i reboot into the cwm,it can't be mounted again.it seems that i can flash the userdata but i can't format or wipe or modify...
and i tried to reflash the bootloader from a well-mailfunctioning deivece,not working,either.
then i go for searching the situation in google,i found there are a lot of similar problems of the tegra device,and the solution is nvflash...
i don't know if there are a block saving the information of partitions just like the PIT file of my galaxy s2,seems we should wait for nvflash?or the method to flashing PIT partitions file?
i installed the nvflash driver by modifying the usb id,but i can't do anything from nvflash,it's not matching.
I had the same problem after I upgraded to JB with CWM recovery 6.0.14 and I tried to root it. But it stuck in acer logo. Then I went to recovery mode, but it couldn't mount sdcard or external card, too.
In my case, I solved it by these steps:
1. Try to go to fastboot mode by press vol (-) + power. After it vibrate, release power, and then play lock button. Then tablet will go to fastboot mode. http://forum.xda-developers.com/showthread.php?t=1861092
2. Download these boot and recovery images: https://www.box.com/s/3321wf8gg4at639nfn06
3. Try to flash these boot and recovery images to table:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
And then, reboot tablet:
fastboot reboot
WOW, my tablet works again.
:victory:

Unfortunately, although somewhat similar, this is not the same situation as the OP had.
The first CWM originally posted a few months ago, was posted by a user who used the totally wrong partition tables, and also, didn't own the tab so it was never tested (after the fact). Basically, it damaged the chipset which required a motherboard replacement. Not to mention a specifically nasty Data_Cap bug in the CWM kernel. No image flashing via fastboot (and probably NVFlash) would repair the damage. The result was several bricked tabs till the CWM was removed. (mine included)
Also note, that the current root procedure is by the same person. Although there is an alternative.
What you had, was simple data corruption on one of the Dev Blocks. This is why you were able to fastboot an image.
Corrupting a partition can happen at any time. Whether rooted, stock, or custom rom. So it's always nice to have ADB to pull your partition images. Just in case.

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.
Hi guys,
So this is my first post but I've been on XDA for a long time. I've been looking for an answer to this problem, and I haven't been successful in finding a post that regards to my situation...
Ok so I just got my tablet today. I upgraded to JB and then I unlocked it using the asus unlocker. I attempted to install TWRP, but when I use .blob files and attempt to load into recovery it didn't work. Anyway, I looked around and I installed CWM recovery instead.
I installed v5.5.0.4 following this guide:
http://theunlockr.com/2012/05/25/how-to-install-clockworkmod-recovery-on-asus-transformer-tf300t/
Now, I notice it's written back in may of 2012 aka before jelly bean... anyway so I installed this using fast boot, and booted into recovery and it worked. I believe I installed the ICS version of CWM. I tried to install Clean Rom v3.3 and I just get bootloops. I can still boot into fastboot and clockwork mod fine.
I tried to install v6.0.1.4 via this thread http://forum.xda-developers.com/showthread.php?t=1846554
But once again if I boot into recovery it just does nothing and reboots after a few seconds.
I re-installed v5.5.0.4 and I can wipe data/install everything just as I normally would, and I still have access to Fastboot. Can I get some help on how I can 1 install the correct CWM and 2 install a working rom? I don't think I bricked my device just yet since I can still flash in fastboot etc.
Thanks guys!
You cant't wipe data from bootloader menu, If you do that, you will get unrecoverable brick.
Sorry I believe I mislead you -> I wiped data from within CWM.
Anyway, I used this thread:
http://forum.xda-developers.com/showthread.php?t=1757077
I went back to stock and I think i'll stay there for a little while longer, this process made me nervous (I've rooted my thunderbolt, droid DNA, galaxy tab 2 7" and my friends phones) so anyway I believe I installed the wrong CWM and that caused errors trying to install a JB rom on a ICS CWM... If you have any insight let me know...

My suggestion is to flash the latest stock JB blob.
fastboot -i 0x0B05 flash system blob
fastboot -i 0x0B05 reboot
Once you get it sorted then flash the latest twrp for jb.
Now, when I try flashing blobs and I go to boot into RCK (I believe that's the term...) it just reboots the tablet instead of booting into recovery.
Android software is out of my element, if this was some C (somewhat similar to C) or Matlab I would better understand (I'm a senior Mechanical Engineer in college)
Edit:
Ah didn't see your post. I did what you recommended, and actually, while my device said it was on 4.1.1 JB, when I hold pwr/vol down I see a completely different menu now than last time, so I wonder if perhaps my OTA didn't correctly load everything from the firmware update hmm...

The same way you flashed cwm.
Windows? Start - in search type cmd - press enter
In the cmd window cd to the directory with fastboot.
Hook cable between tablet and usb port on computer.
On tablet hold power and volume down till you see the bootloader menu.
Down volume till you are at the usb symbol - then volume up.
This should put you into fastboot mode - use the commands above.
Wait till the first command completes before you give the second command.
[INDEX][04 Feb 2013]TF300T & TG-INDEX of Roms/Dev Guides/Kernels/Recoveries/etc. You will find the stock firmware here as well as most other needs.
You will have to unzip to get the blob which you should place in the directory with fastboot.
Thank you very much.
So after flashing the most resent blob, I successfully installed CWM recovery and successfully flashed a rom. I'm not sure what the issue was before. Thank you for the help! much appreciated.

Ive been running KangVIP with no problems, however I got some adware which refused to go away, so I attempted to factory reset via the phones menu. It then ended up stuck at the TWRP screen. This has happened before so next I tried to restore a previous backup...not successful. I can't access fastboot and rescue to flash the official recovery.
Anyone got any help? Is there a guide to flashing the stock rom or have I borked my phone?
You can not shut down the device and connect it via USB to a PC and boot while holding volume down button into fastboot mode?
Well then you have ruined your phone.
I'm OP, was unable to get into my usual account last night. I'm not sure how, but holding volume up, down and power seemed to kick start it back to life and I'm back running KangVIP. I don't think I'll be resetting it again for a very long time.

I'm not sure whether it was luck or not, but all I did was to go into TWRP and then chose the Mount option, unmounted everything, then went to Reboot and chose Bootloader - that got me back to fastboot where I was able to flash the stock recovery, do a factory reset and get my phone back.
i have similar problem one friend use kingroot change to tpwr. now i try restore frimware but fastboot on screen say unloked on red text but commands not alowed.
and android os not have R/W /system only can r/W on tpwr i try use file explorer remove king root but no boot
who to clean rom? for update.

So, I just decided to try and Flash the old TF101 with Katkiss 6.0.1 and Gapps, but I always get stuck on the same problem.
My TF101 is running Android 4.0.3 ICS and USB Debugging is on
I downloaded TWRP app on the transformer, as well as the latest .blob flash file through the app.
Before this, I rooted the tablet using Kingroot.apk, which worked. When I went to flash the tablet with the recovery, the app noted "Recovery Partition not found".
I tried to boot into recovery mode on my own, (Pressing Pwr + Volume down , Then hitting Volume Up), The android screen popped, up and then flashed to a fallen android with a red triangle.... The screen stays on this for a minute and then boots into the normal system. I can't even boot into recovery through ADB, using the
Code:
adb reboot recovery
, The tablet will just reboot normally, not into recovery mode.
The Device does recognize through ADB....
Is my recovery partition just non existent? Even when I just let the system though without pressing volume up, it only gives me the option of (Android) or (Erase Data). when I click erase data, ill stay on the asus loading screen indefinitely and nothing will happen until i turn it off and on.
I just cant seem to boot into TWRP for some reason, and that means I just cant install the downloaded custom ROM.
How Can I fix this and boot into TWRP? I've tried for hours and have been hung up due to the same problem each time, even after rooting.
Did you already solve that problem? I also need a solution.Thanks
