[Q][A700]How to undo CWM and restore factory recovery - Acer Iconia A700 and A510

Hi,
I'm in the situation of having a working tablet, but the dodgy version of CWM. The original thread has been deleted and I remember there was adb command at the end to stop the original update.zip from flashing the factory recovery, but not what it was so I can reverse it !
So if anyone can help me out, that would be great, so I can avoid a bricked device !

go finding a original recovery dump,and flashing it in fastbootmode.

Has anybody been able to find a stock recovery for the A700? JP, I also flashed this broken CWM, thankfully I haven't used it but I want to put the stock one back on to avoid any issues.

reflashing the official update.zip
but,delete the first and the third comands in the updating list,this could avoid wiping/formating action to avoid damage to the /data partition.

Thanks! However, the US Version doesn't have an update for it, at least not yet, and I haven't been able to find a stock US A700 ROM.

So we would need to rename the install-recovery.old back to install-recovery.sh in /system as this was disabled in CWM ??

So has anyone managed to successfully put on the stock recovery ?? !!

Take a little advice folks. If you don't know what you're doing, and your tab is running fine, don't be messing with anything. Just leave it alone til a better method comes.
My guess, if you rename your recovery.sh, is that when you boot, you will either get;
A. a "loading recovery kernel" message that just stays there
or
B. an "invalid recovery image", or something similar.

That's what I'm doing, I'm just leaving the CWM on there until somebody comes up with a fixed version.

I don't understand these instructions. What original file is being replaced? What update.zip are you referring to?
EDIT
Well, I tried to swap out the update script that came in the ROM: SDs_Acer_A700_AV043.RV00RC00_AV043.RV07RC04_EMEA_CUS1, with the one provided above and seemed to have made some progress...I put on an external SD card and renamed to update and then flashed it through the CWM recovery and it completed. A random offset was noted and then the SD update completed note. However, when I rebooted the device it stuck at the Acer logo and never went any further.
EDIT
So, it then occurred to me that the flash through CWM was probably only partially successful - maybe the replacement of the recovery worked. So, I took the same ROM I noted above, unmodified, placed on the external SD card, renamed, etc. and flashed it and it worked - I never saw any signs of CWM during this process. I hope this helps others too.
EDIT
Looks like I spoke too soon...the flash never got past a 1/4 of the progress bar. Looks like I still have a non-functioning device.

Hi, I'm a A510 user. I used the CWM to wipe data/factory reset, after that i cant flash any zip, and even cant enter the system. When i turn on the tab, it stuck on 'iconia tab' LOGO, I tried to hard reset, then i got a 'Unrecoverable bootloader error (0x19000008)'
I enter the fastboot and flash the stock recovery back. next i use the recovery to flash update.zip as usual, but every time the flash will stuck in 1/5 of the whole progress bar, I changed it with other rom zip, or even change the SD card, it didn't work anyway!
every time the flash stuck in the same place of the whole progress bar, i guess it is not an accident! After read your solution, I check the script in my zip, then i delete 2 lines about 'format' command. I think this time will be ok! but to my surprise the green turtle fell down when flashing.
I think the idea is great, but it maybe make the script incomplete, so it cant be flash in.:crying:

[Q] Getting Back to stock WW Rom

Whats the best way to get back to a stock rom after using a custom rom from US region. Obviously I'm rooted and CWM installed. If I put the ww rom on the sd card and rename in asus\update to higher number it tells me there is an update, but when it tries to install it, it jsut goed back into CWM. Should I unroot 1st so it will the run the normal recovery? or is there any way I can convet a stock rom to a CWM .zip file to get back. If I point CWM at the zip file, it does some stuff then fails on me. Anyone able to point me and anyone whos interested in the right way to do this without bricking our devices
I am on a custom 3.1
Should I unroot using the blob in the 3.1 rom, and the try running the update from asus/update directory? I am just afraid of getting to a point where I can't go back or forwards, because I will lose clockwork to put a custom rom back. The nandroid backup I did before installing the 3.1 wont restore saying it has a bad MD5, so this has been no help to me
Cheers
Thanks

^This Anyway, I flashed back to Prime v1.3r2, then pushed the blob from 8.2.3.9.
Sent from my HTC Eva 4G using Tapatalk
Ok So I fo;;owed the unroot tutorial, using the blob from the US 3.1
open cmd promt window type the following and return after each.
\cd
\cd AndroidSDK\platform-tools\
adb devices
*adb your device make sure it is hooked up and id'ing your transformer.*
adb push blob /data/local
adb shell
*at the # type the following*
dd if=/data/local/blob of=/dev/block/mmcblk0p4
*wait a few mins to be safe*
now reboot the device, on reboot you should see a progress bar indicating the flashing of the “blob” file. this will remove the clockwork recovery and put your tablet into BOOTLOOP this is ok.
But one I get to this the tablet boots into android, all sign of CWM and root have gone, but I now cant flash a WW rom on top. If I place in ASUS\UPDATE on the SD, it see the update and reboots. I get a big android with cogs that spin for a while then it stops with a big exclamation mark. If I try doing by renaming to EP101_SDUPDATE.zip on the root and doing power up volume down etc, then i get the android with cogs, and the same happens.... HELP I'm stuck!!
Ok I managed to finally get back to ww .13, for some reason .9 would not work, it locked up as explained above. On restoring .13, I hade to do a factory reset as load of things were crashing all over. But that's fine. At lease now I can return as stock. If anyone has to do the same and is struggling, pm me by all means

[SOLVED] Soft Brick... Can't install ROMS and pushing does not work.

First of all I decided to install CM10 without making a backup on TWRP 2 (clever Kyle). Then when it was stuck on the bootanimation for about an hour, I got annoyed and looked through the forums for help. "Factory reset, clear caches before installing etc" So I deleted the ROM, factory reset via TWRP, deleted both cache and then tried to install CM10. Failed.
Then I tried to mount the SD card to my computer to try to find other ROMS to install. Viper and Energy both failed. I then tried CM10, Viper and Energy with CWM 5.8, and the installation of all gets aborted almost instantly, which I am guessing means that it failed on there as well. I then tried ADB, and pushing keeps failing. Does anybody have any ideas at all on how to get just any ROM onto the phone so that I can get the official 4.1 update again (my phone was on 4.1 before trying CM10, so the HBOOT is most likely 4.1 as well). Any advice would be greatly appreciated, because having a £350 paperweight is not what I particularly want, especially considering I have another 9 months contract to run and no spare phone on the same network as my current contract.

When you say that installing ROMs fails and adb pushing fails, you should tell us what error messages you get.
If you can still get into bootloader, you're probably going to be fine.
First, check that you can mount your sdcard in recovery. I don't mean mount onto your PC over USB, but just mount the sdcard partition onto the root filesystem.
If you can not get into recovery, re-flash one.
If recovery can not mount the sdcard, then you have to go to the sticky on how to fix unmountable sdcard. It involves flashing a stock recovery and then clearing storage from bootloader.
If your recovery is good and your sdcard is mountable, adb pushing should work. If it doesn't, post error messages. Make sure your sdcard is mounted before you try to push fils to it.
In recovery, format system, data, cache, but not sdcard. Then flash a zip. Then boot back into bootloader/fastboot and fastboot flash the boot image that comes with the rom. (Did you do this last step when flashing other roms?)
If this does not work not for you, describe in detail what you do and what you see. If it does work out, I suggest you make a nandroid backup so you can get back to this state, and S-off the device.

You get this:
cannot stat 'ROM.zip': No such file or directory
..because either you have not mounted your /sdcard partition, but more likely because you dont have ROM.zip in your working directory.
Either move ROM.zip to the same directory where adb sits, or use:
adb push C:\full\path\to\rom.zip /sdcard/
Also, is the file youre trying to push actually named 'ROM.zip' or something else, like ViperOneS_2.1.0.zip or so..

The flashing instructions for your ROM will likely state that you have to 'flash the boot image (or boot.img or kernel) in fastboot before booting into the rom.
You can find a file named 'boot.img' inside your rom zip. You have to flash that in fastboot. You can do it before or after flashing the rom, but you must do it before booting into the rom.

All the boxes are ticked on the TWRP Mount screen, including System and SD card. And yes, I did make sure that it is:
1) in the same folder as the adb
2) called ROM.zip. I tried re-naming it CM10.zip and tried that in the adb and still no luck, without without the .zip file suffix.
And usaff22, does that involve unzipping the ROM that I am using?
Okay, so the boot.img was flashed successfully. I then went back onto TWRP, tried to flash the zip and it failed...

It can not find the local file. Make sure the file is not actually called 'ROM.zip.zip' (with 2x .zip ... you seem to have extensions hidden for most types but it shows .zip).

Which version of TWRP? I don't use it, but I read that the latest version has issues and you should use the previous version (2.2.0? I dont know).
Also, does it say anything interesting when it fails?
Before flashing the zip, did you format your system, data, cache partitions?
EDIT: After repeatedly trying to adb push, I finally got CM10.zip.zip onto the phone. Flashing took a bit longer than last time, but booting took no time at all. Thank you touch of jobo and usaff22, your advice was a lot of help.

TWRP and CWM are both fine for flashing ROMs, just not this specific version of TWRP. Since I dont use it myself, I dont know the exact version numbers, but read around a bit and you'll find what worked for others.
Maybe flashing a different recovery will even get rid of your protocol error.
If you've made nandroid backups (I guess you havent or we wouldnt be here.. sorry) you should stay with the same recovery (same 'brand', not same version) or you can't restore them.

The CM10.zip should be on your sdcard, not your system partition. You dont need the boot img at all on your device. You need it on your PC in order to fastboot flash it.
Before flashing a ROM you should wipe your 'system', 'data', and 'cache' partitions, but not your 'sdcard' partition. Only if you flash (a newer version of) the same ROM you have operational, then you can sometimes flash without wiping. This is called 'dirty flashing'. But this does not apply in your case.
Successful flash of CyanogenMod, thanks for the help.
I would like to thank touch of jobo and usaff22 for their help, I just hope that somebody else will see this thread and get all of the answers that they need.

I would rename the zip to something else like sense.zip, place it on the desktop and do adb push C:\Users\username\Desktop\sense.zip /sdcard/
Make sure you use backward slashes for the PC file location, and forward slashes for the phone paste location.
This way we are also providing the full path on the PC.
Also make sure you use the latest adb from the SDK website. You don't need the whole thing, just the platform-tools bit, and replace the files in the new folder with the old one.

Oh, while you're here, another problem has come about. Mounting the SD card will not work, and I can't replace it with a new SD card because... Well, there is no removable cover. I know how to fix it, I've read enough on here to find that out, but the only thing that I am missing is a stock recovery image for the S4 version (CID is ORANG001 if that is required) so if anybody knows a link for this then that will be greatly appreciated.

You might be able to find an RUU lying around on one of the websites which give RUUs such as androidfiles.org/ruu
I tried looking, but no sign of an orange RUU. An easy way to overcome this would be to change your CID to HTC__001 and use an unbranded RUU.

You can extract the recovery image from any RUU or OTA. Recoveries do not depend on carrier.
But .. if you can see your sdcard from within recovery (when 'choosing' a zip to flash, or from an adb shell or so) and from within Android, then you do not have The Unmountable Sdcard Issue and you should not go through that process. Only if you get an 'Unable to mount /sdcard' error in recovery.

Yes. You can use the recovery image from any RUU or OTA.
But first make sure you need it. The stock recovery thing is only to fix the situation where your sdcard is unmountable and you get that error in recovery.

This is the thread: http://forum.xda-developers.com/showthread.php?t=1671643
It involves extracting, hex-editing, and flashing a critical part of your device. If you make the slightest mistake you have a brick. However, if you read carefully and double check every step, it's not difficult. Many have done it. Read the thread.
Once you have supercid, you may as well get s-off as well. (This is the thread: http://forum.xda-developers.com/showthread.php?t=2155135 ) That way you can always flash anything.
Whatever you decide to do, before you start on anything, read all the instructions to the end, so that you're sure you can complete the process before you start. Also, before you start any process, try to understand what each step does and why it is necessary. That may involve a lot of reading and searching, but that is a Good Thing in the end.

It is unmountable. I tried CWM and TWRP to no avail. Also, I have HBOOT version 2.15 which I heard is a bugger to work with. Also, I got the ZIP file for the stock 4.1, and I read that the stock recovery is in the firmware folder, but I cannot access it.

[Q] What Options for Flashed TF300T?

I bought a used TF300T, 16GB
Unlocked
It has TWRP 2.4.4.0, JB 4.2 bootloader, and EnergyROM 3/28 10.6.1.8
Kernel 3.1.10-g59bc3cb
I was wondering if I should leave it alone, or restore it to factory. Is that even possible?
If I keep it as it is, how do I update?
I knew I should have bought a virgin Asus, lol.
Thanks for any info!
You can restore it to factory by flashing a stock Asus blob in recovery (I recommend using the 10.6.1.8 ROM since that was the last one on your tablet). It will wipe all data, including whatever's on the internal storage. Once you get that set up, flash the OTA updates incrementally to avoid issues (there are only two updates to flash). You just have to download them (one at a time) and put them in /sdcard/ (that's where you start upon opening the file manager) -- be sure to unzip the downloaded file once, so you end up with another zip, and don't unzip that one. Reboot, and the tablet should notify you of an update. Repeat for the second update, and you should be exactly where you want to be.
All the blobs you need should be on Asus' website. If you need more help, there are lots of "how to flash back to stock" threads with instructions. Just read carefully, and if you decide to flash a custom recovery when you're done, DO NOT flash one with "-JB" at the end of it or you could brick your tablet. You will need a recovery that ends in "-42". Be absolutely sure, because there are 3 different bootloaders for the TF300, and flashing one from either of the other bootloaders will brick your tablet.

That part of the instructions requires the stock recovery, which you should have if you flashed the stock blob as per the first sentence.

You've flashed the stock blob in TWRP twice already? You're not flashing TWRP afterwards, are you? I've flashed a stock blob in TWRP, and I had the stock recovery afterwards. Are you rebooting into Android after you flash it?
I tried to flash, it failed....BUT this time it worked (??!!) lol.
Obviously I wasn't doing something right, but I have now. I installed 10.6.1.8, now on to the next in the normal manner.
Thanks again!

(Solved) Soft-bricked, but unable to flash anything but CWM.

Hello, I seem to have soft bricked my tf700.
​I flashed a newish pacman nightly in CWM (after wiping data/cache/dalvik cache), which completed with no errors, then I flashed the corresponding GAPPS. But my device became stuck in the pacman boot intro.
​So I tried flashing slimkat which led to my device not getting past the first bootup screen (where you can enter recovery if pressing the corresponding buttons).
​After this screw-up I stupidly hit the wipe data button on the bootloader. I then tried doing the method of using fastboot to erase system, cache, and all that so I could flash system blob of the newest asus US SKU (that is correct for a US bought tf700 right?). Either this or wiping the data caused me to have a different bootloader as pictured below as I no longer have the android button and it does not ask me to press volume up to access recovery (the only way to access recovery is by hitting the wipe data button in bootloader).
​I can still fastboot flash CWM, but trying to flash TWRP does not work as it finishes but going into recovery causes the tablet to just restart. Trying to flash asus stock as above would always give me an error like the one pictured below. Similar errors occur if trying to flash any rom inside CWM via an external sd card.
​I do not have access to adb as i believe i dont have usb debugging enabled since the pacman rom or any other rom did not ever start. It just gives me the device not found error even after manually installing the drivers on two different computers.
Cant seem to get these pics to load, but copying the url and pasting it works.

You probably flashed the wrong Rom. Try flashing the >right< stock Rom and go from there. Double check everything you flash.

Whats the "right" rom here? Talking about the original asus stock rom? I have now tried the the pacman nightly, pacman release, slim kat release, clean rom release, an ICS asus stock rom, and two different versions of the jellybean asus stock rom. These were either done in CWM via internal sd card, external sd card, or done through fastboost flash system blob and flash zip.

Whatever Rom came on the device,(Good thing to have, da) I'm not familiar with this device.

As far as i know, i have installed the stock rom, or atleast multiple versions of it with no success as it gives me an error stating something like staging or system when trying to write it.

Hmm, I'd Download a stock Rom for the device offline, take on the sd card and put it on there real quick and try to flash that, if not, you probably bricked your device. I wouldn't know how to fix it beyond that. Ask the dev that made the Rom were everything that went south and an email to cwm wouldn't hurt either
I am also not sure if I need to have my external sd card formatted a certain way or download a specific CWM to allow flashing the stock rom. Ive spent over 10 hours trying to figure this out, very frustrating.
I have run CWM 6.0.4.6, CWM 6.0.4.7, and older versions to see if I could flash the stock rom with no luck. I have also tried different versions of TWRP but they always hang and reboot my tf700. I get errors ranging from status 6, status 7, cannot mount data, cannot mount staging, and cannot mount system. I am completely lost on what I can do. I have even tried a seperate sdcard to see if maybe the one I was originally using was bad with no luck. GG :/

You gotta stop flashing stuff and slow down!
During all of this you never posted your bootloader version, so you may have been on the wrong bootloader to begin with - who knows.
When you hit the Wipe Data in the bootloader menu you caused the BL do write a wipe data command to the misc partition, causing the tablet to boot to recovery each time you booted (I'm guessing here) and then interrupting it. Usually, with CWM installed, it eventually sorts it out and executes the wipe data command, but that takes hours! You just have to leave it alone.
Hard to tell where you are now since you flashed all kinds of stuff since then.
Can you still boot into the bootloader and have a fastboot connection?
What's the BL version number?
If you boot, what does it boot into?
The picture links are broken - at least in Tapatalk. Post them again?

Yes, the pictures are broken. You can still copy paste the url though. Couldnt figure out why it wouldnt work.
The tablet boots into the first screen that states it is unlocked, but does not go any further.
There is no bootloader version on the top left when holding down power + volume down.
I can still get to the place where it allows me to wipe data or fastboot, but the android icon to boot into android is now gone.
adb does not recognize my device even after manually installing the drivers, but fastboot works fine.
Is there any other way to find my bootloader version?

Maybe you want to edit your post with the urls then.... Makes it easier for people trying to help...
You're seriously messed up, I think. I see a USB icon in there which would indicate that your bootloader is ancient. But then it says: "starting USB fastboot protocol".
Is that after you selected the USB icon?
Anyway, I think you're only chance is buster99's method to get it back. Did you try that already?
http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
Naturally you have to extract the system blob from the 10.6.1.14.10 US Asus firmware, but then you can try to fastboot flash it with buster's method.
Good luck!

Its starts the usb fastboot automatically if no input is selected. I had a different bootloader up until i tried that thing that buster did. It always gives me an error like cant write to system or something if i try it.

Which blob did you flash with buster's method?
I'm afraid you flashed something totally incompatible with your tablet...
You did not generate your nvflash blobs sometime prior to this, did you?

I flashed the asus stock rom downloaded from their website. The US version as it was bought in the US (right? 0.o). I hadnt heard of nvflash before trying to install a rom so i did not make a backup.

Are you sure you downloaded the correct firmware? For the TF700?
Do you still have the original zip you extracted the blob from?
Post the exact file name please.

You flashed all of those blobs???
In which order?
With what result?
Jeez - I think you're done for...
Sorry mate, but gotta catch some sleep now. Maybe somebody else has a bright idea...

I flashed the newest one first, and it gave me one of those errors that wouldnt allow me to flash it, and i tried the others with the same result. So technically i didnt flash any of them. I have been able to flash some roms, but they wouldnt boot so i would be stuck where i was when i started.

Right stop flashing random stuff - you have combinations of JB4.2.1, JB4.1.1 and ICS 4.0.3 just listed there.
Let me put a call out to @lj50036 who may be able to save you but if you have messed the bootloader up with no nvflash backups you are not going to be happy with the result. If you can still get to the bootloader screen then he can perform miraculous superhero acts and *maybe* save your device.

[RESOLVED] HELP.. Boot Loop With TWRP and L install

Hi
Earlier I installed TWRP via Philz and that worked fine.
I then reset my phone and flashed Bigxie's Android L, again this worked fine.
I flashed the new radio for the same thread and that worked fine.
I then downloaded CF-Root from here:
http://download.chainfire.eu/363/CF-Root/CF-Auto-Root/CF-Auto-Root-hammerhead-hammerhead-nexus5.zip
Ran the Windows Batch file all seemed to go well. Bootloader was unlocked and the big red android appears on screen.
Phone booted back to TWRP, a script ran and then my phone started constantly booting the the TWRP screen.
All I'm getting is teamwin flashing up.
If I power off it goes back to this loop.
Any way I can get this working again ?
Not worried about any data.. I've got all I need backed up.
Thanks

dont use root toolkits.
flash the factory img via fastboot. then flash twrp again, flash a kernel that allows root, then flash the latest supersu.
Thanks for the reply.
Just want to claify to make sure I don't make it worse..
I've got the L image from Googles site, do I extract the factory.img from that ?
Then flash it using :
fastboot flash factory factory.img
Thanks
Think I may have made things worse..
I extracted the tgz file and while browsing double clicked the flash all batch file.
:silly: Not sure how the hell I clicked it twice.. but it's doing something.. .hopefully not killing my phone.
Any suggestions how I did myself out of this hole..

i dont think hitting it twice will do anything. but you might have to flash the img files separate, as in the flash-all is giving some ppl issues.

Found out how I've managed to double click.. The trackpad on my laptop is playing up.
I'll have to remember to use a USB mouse with it.
The phone has just rebooted and is coming back up.
Thanks for the advise.. looks like it's working.
I'll start a new thread with a couple of follow up questions.
Thanks

When doing this, is there any specific order to follow when flashing all the .img files separately? I am also getting errors stating recovery.sig and boot.sig are missing. Does installing separate also take care of this?

it appears that the flash-all is having issues and skipping. so by flashing them all individually, you will make sure to flash them all.
