Hi,
As the title says, I can't get into recovery. I rooted and installed CWM a few weeks ago (still on 3.1), and now when I press vol- and power buttons the tablet just boots up normally. It does another weird thing, too. If I press only on either of the volume keys, it also boots up.
I'm suspecting a FUBAR'd CWM install, but I'm not sure since I'm no expert.
Also, adb no longer sees the tablet. Typing adb devices shows nothing, and it used to work (otherwise how did I root, right?)
Any ideas on what I have to do? Nvflash a stock blob or whatever it's called?
Did you either intentionally or not run the OTA update? If you OTA'd after cwm - then you will need to unbrick/nvflash. You're behavior sounds a lot like mine, after I tried to OTA a cwm enabled transformer.

For the cwm thing: first of all, with your tablet turned on, try if the VOL UP and VOL DOWN keys are working. Then turn it off.
Press VOL DOWN + POWER until you see a little write on the upper left corner, then release all and press VOL UP.
For adb: turn on your tablet and connect it to your pc. On the screen of the tablet click on the icon of asus sync in the lower right corner then click on the popup. It will search for asus sync on your computer (have you installed it, right?). From that moment on, adb should work normally.
Hope this has helped.
Thanks! adb worked. Still can't get into recovery. I think it's borked, because I used "adb reboot recovery" and the tablet just rebooted normally.
Any more ideas??

Maybe that's it. I'll try it...didn't want to, because I don't want to wipe anything. This nice device of ours is so much more complicated than my SGS
Try this app, if CWM is installed correctly it should work. Cheers.

Thanks! CWM was definitely broken, probably because I attempted OTA update.
So I went and used the guide in the nvflash unbricking thread, and since that guide installs Prime 1.4, I went ahead and updated to 1.7. Now I'm rooted, cwm'ed and prime'd!!!!

Ok so i've looked, cant find anything to help me out here... Its always possible i used the wrong search terms but i think i did pretty good...
Anyway, i had flashed i believe a CWM version of ICS when it first came out because it was easy to do, and i was able to keep root. Well I ended up with the CWM Recovery version that had the problem of constantly booting into CWM, so i fixed that and the tablet was telling me there was a firmware update, so i did it..
Now im stuck at the splash screen... When i try to boot into Recovery, it says its loading the recovery image but never does anything else. When i tried to load the other screen where you can choose recovery or the OS, i think people call it the linux screen? I dont remember, but when i did that, the big battery meter displayed on the phone for a second then disappeared... Wont turn on now, so i just plugged it in.. Is there something im missing? Or something i can do that anyone is aware of?
Check if the Android Debug Bridge works, and is your device a B60 or lower, (sbkv1)? If so you can use NvFlash to restore the tab.

Its B90, SBKv2...
Last time i tried to boot, i tried Power+Volume Up and i saw the large battery that android phones typically show when they are powered off and you plug it in.. If i remember right, TF101 typically boots up if you plug it in when turned on, but it turned on, flashed that battery image and shut off, havent been able to turn it on since... Plugging it into my computer though, it wont turn on, plugging it into the wall outlet it turns on and sticks at the splash screen, so i'm gonna leave it there for a bit and see if it charges, then i'll try plugging it into the comp to see if ADB works... I'll let you know, thanks!
To get to recovery its power +vol down. Power + vol up gets you to apex mode, blank screen.

.....don't know if I read all your info correct but to enter recovery is volume down + power until you get a message at the top of the screen then you let go both and press volume up to enter recovery or if you don't hit volume up it takes you to the cold boot / wipe data screen.
Yes, i posted that... I tried booting to recovery and it freezes when it says its loading the recovery image.
I was trying other combinations trying to remember the linux screen or whatever it was called, but either way. ADB mode doesnt work, im stuck at the splash screen.
SOLUTION: Do not do the update after fixing your TF101 if you have this same problem, because you'll have it again! Either way, here's what you do.
1) Since you cant shut off the TF101, hold the power button until the screen goes blank, then immediately let go of the power button and hold volume down. 2) The splash screen will re-appear, dont let go of the Volume Down button until you see the text at the top left corner of the screen prompting you to press volume up to enter recovery.
2) Dont press Volume Up since it will freeze trying to get into recovery. Instead, just wait and make sure your not holding down or pressing any buttons.
3) After a few second, you will be presented with two icons, one to wipe data and one to boot android/linux, selecting android/linux WILL work and boot, but you'll have the same issue as before without fixing anything if you reboot again. Follow the instructions to wipe your data. YOU WILL LOSE EVERYTHING!
4) At this point, Recovery still wont work. Boot your TF101 and get it setup and use the Play Store to download a terminal emulator
5) Open the terminal emulator and type SU and press enter, confirm superuser access.
6) Type in the following and press enter when done: echo boot | dd of=/dev/block/mmcblk0p3 bs=1 seek=0
7) Restart your transformer, let it boot normally the first time, after that, recovery should work.
8) Problem solved, DONT install the update this time! Install a custom ROM the typical way using CWM, and your set!
So, one thing i've noticed is im being spammed out of my mind from the OS to do that system update, so i've found that the best thing to do once your bootable, is to flash a custom ROM.
I tried this but went back to the same ICS version I had before, and ran into the same problems. Ended up with a whole other ROM, and now all problems are solved!
Good luck to anyone that has this issue!

so you lost all data, all apps, all settings, all the effort and work and time to config apps and settings... UGH
I am in the same boat on my TF201 after the JB update bricked my tablet... really pisses me off as Asus says RMA it (which you know they will just wipe your data) or wipe the data yourself and hop it works. So badly want to salvage my app settings and all the work I did to trick out my tablet. F***** Asus, their own update fried my tablet.
So I flashed my Trio Stealth pro 7" Tablet, which is a knock-off of the Ly-f1 tablet. I apparently used the wrong .img, because on the first boot up, the touchscreen does not respond at all. The screen displays a "Encryption Unsuccessful" error, and asks me to do a factory reset. Holding down the volume button and then powering on the tablet displays a black screen with nothing on it. Upon trying to connect it via USB to my computer, it is not recognized, and I'm not able to find the Drivers for my device. I now have the proper .img file, but I'm not able to get into recovery to flash it. How would I do that?
Thanks.
Bmorn V11, Goclever A73, Eken T02, Aldi Minitab, MyAudio Tablet Series 7, ASK 748SP at the very least look the same and are probably the same tablet. So much so that I ordered a Bmorn touchscreen for my ASk tablet and it worked. ...until I factory reset it from settings a few weeks ago, since then it started freezing up ocasionally and now I get stuck at one of the 3 boot logos but I never see it boot all the way. I hope it's not hardware failing.
I found a button behind the microphone pin-hole after trying vol + and power + home and the like for hours. Can someone please tell me how I get into what i presume is called recovery mode ? I tried pushing that hidden button with the power button, but it doesn't work. Is there even a recovery mode for this device ?
Someone claims there is no recovery mode and vol + and power should work ? So what's the deal with the button behind the mic hole ? http://forum.xda-developers.com/showthread.php?t=1406429 "The device was strangely rooted when I bought it from the retailer. The instruction manual strangely says to boot into recovery mode by holding Vol + and the power button. I called the support company and they said that a recovery needs to be installed first. Using Root Explorer there is no recovery folder. (/recovery) - is there supposed to be?"
I'm on linux, do I really need windows to flash this ? If I fail, can I try again ? I used to get along computers really well, but android is currently totally confusing me. I found several images that might work, but I really don't mind trying out unofficial images. If I can try them one by one I'll figure it out eventually, but I'm afraid I might brick it or something. I've read about flashing bootable SD cards, but I guess that won't work here ? Nor will the images that are supposed to be flashed to an SD card work ?
I guess I'll have to bet on an image and find a Windows (I'm on Linux) machine and the rest is trial and error ?
Is there a page somewhere I could read to figure out the basics ? I feel really confused by all of this. Thank you !
I also found this thread: http://forum.xda-developers.com/showpost.php?p=23769918&postcount=3 which explains how to flash this, but maybe i don't need to go through that if there is a recovery mode ? And it also seems like those instructions are for t01, and it doesn't involve that hidden button at all. I guess this isn't what i need, right ?
I guess this should work:"Turn off your tablet.
You will find upgrade button located in microphone hole on the right side of your device. Press this button using e.g. paper clip. Next connect your device to your PC while
holding upgrade button" (http://www.goclever.com/data/upload..._d4d0bde076ab401d6cb98bb1b77713165b6ffb11.pdf).
I can't turn off my tablet. All I can do is force it to quit by holding the power button for 5 seconds, is that enough ?
I managed to get adb and although lsusb lists the device, I can't connect to it with adb. After a minute or two lsusb doesn't show the device anymore either. Do I need to have debugging enabled or something ? I was hoping to reset it with
Code:
adb shell
recovery --wipe_data
Hi All,
I have china tablet:
Model: A70H
CPU: Allwinner A23
OS: Android 4.2.2
Spec like: Eken_A70h
I has encountered situations :
I use adb tools, then I type: "adb reboot-bootloader" command. As a result, the tablet has hang on bootloader screen can not exit, even I shutdown and reboot using the power button. I checked in the computer-device manager, I see : Android Bootloader Interface
I can not exit this bootloader mode, please help me. thank you!
After spending an entire afternoon researching this same issue, I have found what I think is the answer.....The Allwinner A23 tablet does not utilize hard reset keys. All the info that you read about on the internet about holding the power key with the volume up or down key, etc., does not work on these tablets. Strangely, at least for me, the answer was wonderfully simple - hopefully some of the developers here will test this on these tablets, as, if you look through the internet, these Allwinner tablets are getting more and more popular. So, the fix that worked for me:
Turn your tablet on (you will see the little Android icon or similar), and leave it on until the battery completely runs out. Now plug it in to your computer or power source and turn it on - for about 5 minutes or so, you will see the battery icon, which will turn off almost right away. Once the tablet gets the slightest charge - voila - the OS loads. It was like a miracle for me, and hope this helps you too.....
Not my tablet,, A23, QA88-V1.3 2014-04-14 (from tmart)
As you say vol+, vol-, vol both does nothing. Tablet has no home or back keys
After discharge, plugging in brings immediatly the little android figure, the boot logo
(both power and micro usb)
I got the boot lock by adb reboot bootloader,
perhaps I will have to use phoenix card
dmesg and lsusb do not change when it is plugged in
So fastboot devices find nothing
Any suggestions??
I take back what I wrote above, I put the tab aside for a month or 2, the battery was flat,
it magically booted (after a bit of charge). I don't know how long it has to be "flat", maybe a week?
Now it is looped again, a failed recovery, it will only boot that
But phoenixcard can make a bootable sd, so you can see if it will be compatible before flashing
Lots of very obnoxious dl sites for this firmware,, qa88,, its hardly worth the trouble
I have been hammering on my tab for a few days now,,
the bootloader and recovery are crap software.
Maybe that's why there are no keypresses
My original, at least could get to recovery, but the vol keys were dead,
so all I could do was reboot
All 4 of the firmwares I have found bootloop when you try to go to recovery
(and there is no adb in any of these when bootlooped)
There are more than 4 out there, but when you md5sum , it's just a different name
Fortunatly most of these bootloops have been on a sdcard boot, so I just fire up
PhoenixCard again and rewrite the sd
If you play with this, you better have a good firmware and TEST it with a sd boot,,
and you will lose whatever config you have done
there are perhaps 2 more unique firmwares I haven't mange to get yet, I have hopes
(I prefer 4.4 to 4.2, but the with the navcity 4.4 the camera doesn't work,
I have edited script0 and init.sun8i.rc , maybe the order of module loads matter)
Most of the firmware is 4.2, only 2 4.4 (AFAIK)
BTW, this is a QA88ver1.3, JDQ39
