You are on stock recovery if you get the !
You probably mistakenly flash the stock recovery before you flash the repacked ROM.
Easiest thing to do now is install CWM recovery again.
Download a stock firmware from Asus website and flash it with CWM recovery.
That will put you at stock firmware, unrooted and stock recovery.

What CWM version are you using? If its the lastest from Roach, it only flashes from the internal memory, not from sd card.

Lenovo A789 APKHOT camera not working
Hello folks!
I've got a Lenovo A789 since few days.
The phone came with apkhot (APKHOT_A789_4.0.4_0808) Rom installed from the seller.
But I've found a nasty surprise: rear camera (the 5MP one) isn't working at all: when I launch Camera app only
the front one works and there is no way to switch to the other.
I've tried to install other camera apps (like Camera zoom) but they all hung with error messages so it seems
that camera isn't supported by this rom.
I've read the forum related to installing Cybermaus Rom - A789_ROW_S106_cybermaus_ICS_v3.11.zip but I would know if there are issues to install it by CWM Recovery starting from APKHOT Rom.
I have CWM Recovery 5.5.0.4 installed that supports recovery from zip files.
So anyone has ever done such recovery?
Is it a risk free operation? Can I proceed?
Thanks
Vic

CWM Recovery 5.5.0.4 it's all you need.
You can install Cybermaus Rom or andrea_d86 rom (mine, link in my signature) or which other you want with that recovery.
The risk are very low, just be sure the battery is charged and follow the instructions carefully.

Do you know if cybermause rom istallation will leave CWM Recovery intact so that I can roll back to APKHOT or install
another Rom (the yours for istance)?
Have you ever known about camera not working issues with any custom Rom ?

Hi,
when the phone is completely off, push the power button and release after 3-4 seconds then suddenly push in the middle of volume buttons (+ and -) and keep pushed until the recovery starts.

hello, thank you.
I got access the cwm recovery by pressing the volume up and down, before pressing the power.
The cwm installed this on my phone is 6v.0.1.1 compiled by Dean @ etotalk. You can install the ROM andrea_d86-4.0.4-lenovoa789 by this version of CWM recovery installed on my phone?
Again, thank you.

hello.
To update the ROM of my other phone I needed a file. "Img"
To upgrade to this ROM Andrea, I need some file. "Img"?
I read the tutorial that explains the CWM.
As I am a layman on the subject, could you pass me what steps I have to do?
Thank you.

No, you don't need to flash any ".img" files, just install the rom through recovery.

Hello, Please, Could you help me, again
How can I make apps to be directly installed on the SD Card, especially games like NFS SHIFT?
I already went into settings, storage ... but it did not work.
I also did the tutorial http://forum.xda-developers.com/showthread.php?t=1788594, but neither worked.
Thank you.
Hey andrea,
I just have a question before reflashing my whole phone again.
The only thing I'm missing in cybermaus ROM is multilanguage support. Also with one of the locale apps a lot of menus and apps are in native english.
Is your ROM different (so all languages are in all parts of the phone working and not just in some) and when yes, what did you do to get it work to properly?
Is there a way to install that feature afterwards without reflashing?
Thank you very much for reply.
Some help to install the ROM in my A789
Hi,
Some days ago I bought my A789, it isn't rooted and it there isn't CWM installed, just the original recovery. So I have many questions to install a new ROM.
1) To install andrea ROM in a original A789 I have to root it before?
2) If I have root my phone, how is the best way to root it? I tried unlockroot and it didn't works. Install CWM is a bit confused for me, maybe beucause I've never done it before (I am a newbie).
3) Following the steps described by nayton sanches can I install andrea ROM?
4) How dangerous is install a new ROM? Is there any way to backup or save the original ROM?
5) To install a new ROM where is the right place to save the ROM? In the SD card or in the root of the phone memory?
I know all of this questions are very basic for all of yours, but I am affraid to commit some mistake and destroy my phone. I want to update my phone because the multilanguage feature, I am from Brazil.
Plese excuse me for my poor English.
If someone could help me I am very gracefully.

No, the multilingual isn't a patch, is bound with the framework.

1) It's not necessary
2) ---
3) Yes, but first you have to install the recovery following the guide in my post
4) After you install the new recovery you can backup everything (rom included)
5) Just put the file in your SD root folder

Can you enter "DOWNLOAD" mode?
first, please provide your steps from rooting to flashing rom.
and also provide any kind of information of recoveries, roms, gapps, kernels, etc you're using.
so anyone can help you better..

Thats needed in most cases right.
BUT
Simple solution is just reflash stock. The error message means he has stock recovery installed.
Just need to know if you can enter "DOWNLOAD" mode

i'm just misdoubt that he flash something incorrectly you know
because he said that he can get to the recovery, but seems that he doesn't know what means recovery is
so before i say futher the solutions or what might causing the problems, it's better to know what he's knows first. because if i explain something that he doesn't know, things will be more complicated heheh :laugh: :laugh: :laugh:
like my words haha :laugh: :laugh: :laugh:
Actaully tried to upgrade to android kitkat 4.4 from 4.2.2
but error generated and even coundt restore the backup.
now the stage is, the screen never goes off until battery runs out.
the screen appears with android logo
"Android system recovery <3e>"
reboot system now
apply update from ADB
apply update from external storage
wipe data/factory reset
wipe cache partition
apply update from cache
I tried all options, but didn't work.
even the tablet is not being connected with laptop.
so only option is, if reflash stock done from SDMemory card ?
kindly guide me the suitable steps.
You can't just flash kitkat roms directly from stock recovery,, you need a custom recovery to do that,,, here is the work around :
1 first reflash stock rom again
2 secondly flash a custom recovery from odin ,,, use luigi way of one step recovery and root
3 after that when you are able to boot into custom recovery,make sure you have cwm recovery >6.0.4.5 installed otherwise you will not be able to flash kitkat roms. For the record, you can flash phillz recovery 6.19.6 from custom recovery.
When you are done,please come here again

Place the .zip file on the root of your SD card, boot into recovery, flash the .zip file (no need to wipe anything) reboot recovery, you should now be in new recovery, reboot phone.
Or go here http://forum.xda-developers.com/showthread.php?t=1306450 this is an excellent app that will allow you to install recoveries and kernels
