Hey guys, just wondering if any of you know a fix for this on my WIFI only xoom
Using the guide from here about Wifi Unlocking and rooting Ive unlocked the bootloader on my Xoom. Ive flashed Clockwork and am up to the part where I have to boot into clockwork recovery to install the root tool, however there is no option to enter 'Android Recovery' when I push the Down key on the dual core boot screen, during the first 3 seconds of the first boot after flashing. Theres NVFlash, fastboot and another but no recovery.
I am able to get into recovery via the ADB REBOOT RECOVERY command however I dont get into Clockwork and am stuck on a screen with a green android logo in the center. Pushing any manner of buttons does nothing and the tab automatically resets after 2 or 3 mins in that mode. Has anyone else seen this and know of a fix?? Ive since learned that if you allow the tab to boot into honeycomb it installs the stock recovery and you have to start over by reflashing clockwork, as stated tho no Android Recovery option appears. Any ideas?
recovery is not installed properly.
put your recovery file in fastboot folder
rename it to recovery.img
in fastboot run: fastboot flash recovery recovery.img
this recovery file is not zip file but .img file(rename it for ease of typing)
I've done it exactly like that, 3 times now. all the messages seem to indicate its flashed correctly. Heres what it says on the tab:
Flashing allowed for partition recovery
OneWire: Charger not connected
Battery Level 82%
Flashing Stormgr partition recovery Status:- done!
And i get the OKAY's in the terminal box as well. Still no Android recovery menu. I read in a dev post reguarding this same procedure a few other ppl had the same issue. I was hoping sum1 had a fix
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.

Hello Guys,
i have made something wrong. i wanted to install the OTA JB Image from internal SD and i was thinking it would work with CWM.
First step i have made is, unlocked the bootloader with adb.exe etc...
The Second Step was to get root and superuser (here maybe i have done something wrong) but in the end i got superuser to work with a patched bootloader or something.
The Third Step i installed CWM and started to flash the recovery image.
But it doesnt go any further, if i try to go into recovery mode, it stucked always at the message "boot recovery kernel". from here its frozen.
i have two recovery images to choice with CWM, One is calling TeamWin Recovery Image and the other is the CWM Recovery. But both doesnt work. I tried to go directly from CWM to the recovery mode and with the Power Button and Vol + Method. Both not working. If i try to boot manually first it says "it update via sdcard" or something, and immiadately it follows the message "boot recovery kernel" and stucked....Nothing happened
Thats a big problem because i cant update anymore and i dont have an externel sd card here. And via google i cant find a solution to this problem.
Is there a Method to install a new Recovery.img via adb? that work properly?
Maybe someone can help me out?
Greetings
Jack
Sorry for my bad English.
[EDIT] i have solved the problem by my own. I've flashed the wrong recovery img. Now i have flashed that version for ICS with vorbeths Easy Root. And now i can Update the version. Hope there will be no more problems...
Please steps

How did you do that? could please put steps or that alike? I rooted my a700 and put the iconian rom but i wanted to put Cyanogen but it gets stuck like you said, I also installed iconian using Rom managerm please help!
Hello guys sorry about this I'm new to all this. Okay so I unlocked the boot loader and rooted my tablet successfully . I installed cwm and I updated to 6.0.3.1 because it said there was a new update. But when I try to boot my tablet in to recovery mode or boot menu it says entering recovery kernel image but just stays there . I am not able to go on fastboot boot menu recovery mode anything . I am able to use the tablet normally tho but I am not able to go on recovery mode. Did I do somethingwrong or what should i do? I would appreciate some help. Thanks
Re :
Hello,
Did you find a solution ? I have exactly the same problem. My A700 is stuck on this message : "entering recovery kernel image".
I've tried to reinstall Recovery with CMW but the problem is the same !
I hope you have a solution for me

Well, I am going to guess, if you can't do a fastboot flash recovery xxxxxxx.img, and it says successful, but you can't boot immediately to recovery, then more than likely the recovery partition is damaged. And unfortunately, there is little you can do for it except mainboard replacement.
You can try fastbooting a stock recovery image (you can find them here in the forums, just search "stock recovery". Should be ICS and JB available.
If that don't work, Acer Service Center. Acer won't give us the SBK (secure bootloader key) to be able to use NVFlash to diagnose/possibly repair partitions.
I would always advise to NOT USE the Rom Manager app to do a recovery. Reason, you really have 0 idea what it is installing, or who made it.
Is my device soft bricked?
I flashed PhilZ-cwm6-XXLTA-ATL-5.15.0.tar which worked, then I started up the phone and tried to flash CWM 6.0.4.3 touch using ROMManager, the process was a "success" but after the reboot attempt the phone was unable to boot OS nor is it able to go to Recovery mod. I am still able to enter download mod.
I tried flashing PhilZ-cwm6-XXLTA-ATL-5.15.0.tar again, but it didn't work. I can detect my phone in ADB devices and in Odin3. I am currently searching for a stock ROM for my device.
If anyone has experienced this before and knows the result already, could you tell me whether my device is lost or I can revive it somehow? Thanks in advance.
EDIT: My phone doesn't seem to go into recovery, stuck at manufacturer Logo(Not restarting); but in ADB devices I can see it in recovery mod and can see its contents in adb devices.
Solved: It booted normally after deleting update.img and cache via ADB.
