If you unzip the update is there another zip file inside? If there is, rename that one and put in the root of your sdcard. I've done this method muitiple times without any issue. But then I was on jb .20 version. I havent tried it on the latest .25

Archive in the archive, extract the archive and rename the second

So. Describe your problem to solve, who can stalknetsya. Attempts to rollback jb ics failed. With the latest version of the firmware to the previous version of the incident adroidom ends with an exclamation point. What has been tried:
1. Different versions of the firmware off of previous versions (downloaded from hda)
2. Different memory card with fat32 (memory card only pameschalsya archive firmware)
3. Master reset to factory settings
4. Vap
5. Md5 checked for authenticity
6. Tried to rename the file according to the instructions (inside archive) and installed via paver volap, voldaun
7. Tried to put the internal firmware archive to the root of the memory card (do not rename it. Uvedobmenie appears that it has found updates, offers to install, warns that the data will be lost, agree reboots tablet, android falls with an exclamation point in a couple of minutes perezagruzhetsya, a notice "no update have an unknown error ")
8. Tried to rename the file extension and uberat
System applications are not removed, thawed, making the firmware have been made. Tablet and firmware versions us, bought in Kiev. Updates come normally and properly updated over the air. Attempts to unlock not conducted. Serial c8.
Solution is found, we will learn to live without root loss guarantees - not an option. (Already there is one brick from Acer)

Hey I have one more for you to try. I suspect something is messup in the sys files or stock recovery. Download the latest full firmware JB .25 from Asus, then unzip and put the file on root of your sdcard, you should see in notification to upgrade. See if that work.
Tried. Download the latest firmware, removed arhiviz archive and uploaded to the root of the memory card. Even the notice does not appear, restart but no notice

Hi guys I am trying to do this downgrade for rooting, I downloaded the .30 firmware, unzipped and renamed it and copied to sd root, but whenever I boot into recovery (RCK) it displays the working android and right after the dead droid with the exclamation mark. If I do nothing it simply reboots but nothing happens/changes. I am on locked stock un-rooted JB.25 firmware. Anyone have a suggestion? Cheers
I'm getting the same thing when following this procedure on 10.4.4.25. Not sure if there's a newer method to root on this firmware?
Add me to the list of getting the exclamation mark and the dead droid though getting the Signature Match message.
I tried to downgrade to 9.4.5.30, 10.4.4.20 and I even tried to update / refresh my 10.4.4.25.
Only when I put 9.4.5.30 on the MicroSD I get an System Update notification. The others don't trigger that but yet all fails.

So, for those of us who are on 10.4.4.25 how do we revert to a NVflashable version? I'm unlocked but otherwise stock. But, in the event it isn't possible to revert to ICS what's the real world risk? I mean, I've flashed phones and other tablets countless times without bricking. I know that's always a possibility, but you have to almost try to brick a phone. I would think installing TWRP or CWM would present just as great, or greater, of a risk. Educate me, but don't flame me. Are there risks in flashing the TF700 I'm not aware of?
Hi guys just to let you know that I downgraded and rooted my device using the method mentioned here. What I did was downloaded the .30 ICS firmware unzipped (one time) and renamed as the OP mentioned, then I had one copy of this .zip file to my internal memory root and one to an external microSD root. I inserted the microSD on the slot and turned off the tab. Pressed the Vol down and Power button and entered RCK (stock BTW). It then displayed the working driod (no message displayed) and after the reboot I was on ICS (took some while though)!!!! I then downloaded the latest firmware, rooted using the guide on the all-in-one guide for TF700, installed OTA Rootkeeper, temporally unroot with rootkeeper installed the latest firmware, recovered root with Rootkeeper. And now I have a properly JB rooted device. Thanks xda members and all devs!

Cold Boot
I too was getting the exclamation mark and the dead droid. I read somewhere that doing a cold boot cleans useless clutter and makes the tablet run faster. Just for the heck of it I tried doing this downgrade after a cold boot and it worked for me.
To do a Cold Boot:
- Turn off Tablet
- Hold down Power and Volume Down button
- When you get to the menu DON'T select anything. In small font in the top left corner it says "OS will Cold Boot in 10 seconds if nothing is selected" or something like that So just wait longer than 10 seconds and let your device Cold Boot.
- After Cold Boot, turn off tablet and follow the OP.
Good luck.

Full of hope tried a cold boot and a downgrade. Useless for me, still the red triangle / dead droid
Is there another link for the firmware to downgrade to ICS. I have clicked the link in the OP but when I get directed to the Asus support page and select my OS it doesn't give me any OS's to select, just sticks at select OS

This is what worked for me, all other methods described in this thread resulted in the android with red exclamation mark.
No root
Hello guys,
I just don't get it right. :crying: The Downgrade works but for me it is not possible to keep root after upgrading to jb.
I took the "WW_epad_user_9_4_5_30_20120907_UpdateLauncher.zip" and put it on my microSD. Renamed it to "EP201_768_SDUPDATE.zip" and went into recovery. The downgrade process started und I was able to root the TF700 with the "RootDebugfs.bat" method.
After that I installed the SuperSU app, started it and made the recommended update. I even marked the checkbox ota survival in the superuser app. Aftewards I loaded and installed the Voodoo OTA root keeper and said "protect root".
All checkboxes were marked and I hit the button temp unroot.
Now I tried to start an OTA Update but it always said that there are no updates available. I cleared DMclient and CMclient data + force close but no change.
So I took the "WW_epaduser_VER104425UpdateLauncher.zip" Update and updated it to jb again with renaming to "EP201_768_SDUPDATE.zip".
Recovery started. The update goes well but the OTA rootkeeper app is not able to restore root. -> No backup of su-binary available...
What am I doing wrong?!
Unlocking doesn't work either. Problem with internet connection, please try again later. Whats wrong with this tab?!

Same here
Removed the MicroSD, placed the original .30 (not renamed) on the root of the TF700 and the downgrade got detected right away.
I accepted the downgrade and it succeeded (maybe because of the cold reset earlier).
Anyway I'm root again and now downloading the upgrade using the normal OTA.
Edit: upgraded to JB .25 and succesfully restored root.

15Hi.
I upgraded to JB without being rooted, now want root but i'm not ready to unlock bootloader yet. After reading the guide here and seen it requires unlocked bootloader i tried another approach.
WARNING: As always there is a chance something may go wrong... If you do it i'm not responsible for bricks, do it on your own risk.
WARNING: This will wipe your data
WARNING: As with all updated make sure your battery is charged
This is what i did:
1. download .30 firmware from asus site that matches your SKU
2. extract the zip file to the root of your microSD card
3. rename extracted file (ex: US_epad-user-9.4.5.30.zip as mine is US SKU) to EP201_768_SDUPDATE.zip
4. insert sdcard and power off tablet
5. press power+voldown, release them after it starts and press volup within 5 seconds to enter stock recovery
6. working android displayed .................. wait patiently to finish update...........
I think this method is peaty safe as is a normal update, no fastboot, root or unlocked bootloader.
I sincerely thought asus recovery will skip the update because is a lower version then the one installed but it did not.22
JB cannot currently be rooted, so you'll need to root 9.4.5.30 first, then use OTA rootkeeper to make a backup of root and enable OTA survival (I also enabled OTA survival in superuser), then apply the JB update, and finally use OTA rootkeeper to restore root.
Also, I would highly advise not installing any apps on it in ICS, b/c a lot of people are experiencing idiosyncrasies in JB that are fixed if you perform a factory reset - since your tablet will be brand new, a factory reset will be a lot less painful with no apps installed.
If you are about to receive your tablet, and it is on 9.4.5.26 or lower, I'd seriously consider first using nvFlash to make a pure backup of the entire before updating to 9.4.5.30, b/c nvFlash does not work on 9.4.5.30 nor 10.4.4.16.
Sent from my ASUS Transformer Infinity TF700 running Android JB (rooted) via Tapatalk11The file you get from Asus is a .zip file. Inside it is another .zip file. Unzip ONE TIME and rename the .zip file while it is on your PC. Then copy it to the sdcard. I used a sdcard reader connected to my PC to copy the file then popped it in the tablet.
when I tried to do it all on the tablet I got the same results. (it no workie)
