[Q] Lost root after latest firmware update - Transformer TF300T Q&A, Help & Troubleshooting

Just wanted to give everyone a heads up about the recent firmware update (build 10.6.1.15.3) for the TF300T. I had root before the update and all was well in the world and then I saw the update notification. I checked voodoo to make sure I had root backed up and I did. I performed the update and now no root and voodoo is not restoring it. I fired up adb and found su binary and busybox are missing from bin and xbin It appears asus decided to overwrite my system directory in this update and wipe out all those files that I so carefully placed to gain root access.
I think I am now officially stuck unrooted. :crying:
Unfortunately unlocking the bootloader is not an option for me for work related reasons. If anyone has any other information about this update or how I can restore root, please help!
Otherwise you would be wise to stay away from this update if you are currently locked and want to keep root.

This might help you:
[JB ROOT] motochopper works! (Root JB 4.1.1 & 4.2.1 with locked bootloader!)
And a little searching might find it even quicker than asking!

Someone just confirmed it is still working with the latest upgrade.
Would have been surprised, if Asus had broken it that quickly.

I got root back from voo doo. In your message you say you had checked root backed up. You didnt say you took the next step and hit temp unroot so that system appears unrooted whilr updating.
Just wondering.

I actually did that. I temp unrooted before I updated which in hindsight might have been part of my issue. Anyways, I am going to be using motochopper to reroot but my tmp directory thinks it is a file now :silly:
I am currently downloading the asus firmware file so I can manually update (even though i am already on 4.2.1) and that is suppose to re-write my system directory so my tmp directory will be restored and I can push all the needed files. I will report back with how it goes.
[UPDATE] I was able to apply asus firmware manually (which factory reset my device in the process) then ran motochopper successfully. I backed up root with voodoo and this time updated firmware OTA without temp unrooting. After the update was applied, I restored root with voodoo and all is well now! Thank you everyone for your help

I lost root as well after update to build 10.6.1.15.3,however, all I needed to do is reinstall TWRP and install UPDATE-SuperSU-v1.25.zip and I'm again rooted. You can do a search for UPDATE-SuperSU-v1.25.zip file here on XDA...it will come up. Hope this helps.

I was able to reaquire root by using motochopper but thanks for the advise. Sounds like your device is unlocked which like I said was not an option for me.
BTW, if you are unlocked, why are you running stock asus firmware??? You can find AOKP builds over at rootzwiki. http://rootzwiki.com/topic/27152-aokp-build-38-unofficial/

[Q] can i use voodoo ota root keeper if i manually update to .29

so i know that i can root it at .17, use the app to keep root, update to .29, and use the app to get root back.
but how do you update it? does it matter if i update it manually (download the file from asus support website, unzip to sd card, install the sd card and an exclamation mark will appear,... [like they say in their website])
do i have to update over-the-air?
and what if after i buy it, the version is .29 out of the box? how can i root it?
another question is what case and screen protector do you use for this tablet? i found a lot of brands but i don't know which one is the best to use
thanks
you can update via ota. just make sure you use voodoo to temporarly unroot your transformer and make sure you aren't using a modified build.prop. if for some reason your tf300t is already at .29 you can just downgrade following the instructions in the development section, it's pretty simple.
i use my device naked. no screen protector. i do use an ipad case for when i'm not using it.

Just received my my prize (see signature!) and it came with the .17 firmware - I've unlocked and rooted using the steps provided here, and after unrooting, rebooting, and trying to do an OTA update, it says there's no update available, after this thing was bugging me like crazy while I was trying to get the unlock app on it to update!
any thoughts? manually update?

You won't get the OTA update since you unlocked. You will need to update manually and re-root flashing a zip with CWM. Check this thread for more info.
Note:
That's if you lose root when updating manually.

Thank you, I figured that's why the OTA prompts stopped.... That's the thread I used to get it unlocked and rooted, so what on there am I looking for to manually root? Just need to download the update from ASUS directly and hope the root holds, right?

If you install CWM or TWRP (recoveries) you will be able to flash ASUS updates and flash a zip that gets you root access, if you do lose root when updating.

Does a factory reset unroot?

I know some phones, like my galaxy s 3 will not unroot the phone after a factory reset and keeps superuser but when i did on my Infinity, it seems like i was unrooted, i didnt have superuser anymore. Can someone confirm if it unrooted the tablet or did it just erase superuser APK?

I cant confirm that with the TF700, but it was the case with my TF201. Once I reinstalled the superuser.apk I was back rocking and rolling along.
ok, and i should unroot before JB updates is available OTA right?
I was rooted and decided to do a factory reset.
I had to reinstall superuser to remain rooted after the reset..
"su" remains in /system/xbin/, while Superuser.apk (the app to control the whole thing, could be SuperSU instead) remains in /data/, as all the installed non-stock apps
factory reset = data wipe = /data wipe
so it will delete your app for managing root access, but it will not delete the SUID su executable, so it will not delete the root (access) in Linux/UNIX terms, you will just need to simply reinstall the app to manage it from the Market (which doesn't require root privileges itself, the app will just make use of them when opened - actually running it once to make sure it works first is recommended)

Sorry, I missed this one (busy time; also, your messages can get lost behind your vast signature! why speedtest?!).
There are various views on this. Some XDA members claim they had problems with OTA updates when rooted, some (including myself) were able to update without ever having to unroot or change anything, but the update will require getting the root (copy of "su") back, see some threads on this here, SuperSU might come in handy.
Basically, if you receive OTA update (or just the notification) when rooted, that's fine, just go through the process. If it fails, unroot first or even re-flash firmware. On the other hand, if you hear that most of the people here are receiving OTA updates and you still don't, after some initial wait you should probably unroot first and then check for OTA. This is not meant to be confusing, just ennumerating the options, as there is some disagreement about the first issue (^).
got it, thanks. Will unroot and stay unrooted until JB, i think it's the best solution

This is the Asus TF700T forum.
I think you need to be in one of the Samsung Galaxy forums.
You can always go to ASUS' website and download the newest ROM update. I did that after gaining NVFlash access. I had to rerun the debugfs exploit afterwards, but it was updated and rooted.
Phone:
Sprint HTC EVO 3D
Root & S-Off (JBear)
HBoot: ENG 1.04
ROM: CM10.1 Wild for the Night
Kernel: Baked-In CM 10.1
Recovery: TWRP 2.4.1.0
Tablet:
ASUS Transformer Infinity TF700T
Rooted, Unlocked, & NVFlash Access
Bootloader: AndroidRoot 9.4.5.30r01
ROM: Stock (For Now)
Kernel: Clemsyn's 1.8Ghz & 700 GPU
Recovery: TWRP 2.4.1.0

[Q] Rooted and can't update anymore

So I've rooted (the day it came out, so before the first update) and can't update anymore. It'll fail when attempting and reboot me. It wouldn't be an issue but I don't like getting popup reminders about the update. I've searched around but haven't found this issue and am hoping I don't have to reflash the stock rom to update again, I'd also like to keep all my stuff you know. Hopefully someone knows a solution. Sorry if this is dumb

Unroot, install update, reroot.
How to Unroot:
Thanks shabbypenguin for posting this.
You can manually unroot your Droid by using a root file manager program (such as root explorer) and mountsystem as R/W. Then delete the following:
/system/app/Superuser.apk
/system/bin/su
and if it has it
/system/xbin/su

Thanks! Unfortunately, it still fails about 10% of the way through the update. Since JB just came out I'll have to just flash to stock completely and try updating legitimately, then rooting it again, I guess.

You may have solved this problem already but did you try using voodoo root keeper? It's a pretty straight forward way of backing up the root, unrooting to install the update, then rerooting when the update is installed.

I'm running into the same problem. Did the flash back to stock and subsequent update to JB work for you? If so, were can I download the stock OS?

Hey there, I had the same problem. Rooted, unrooted, frozen, deleted, restored, couldn't get anything to get JB to work. Eventually just gave up and flashed to stock. Used the amazing Utility presented here
just make sure to gain root access before going to the JB update. there is no present method for getting root on fresh phone with JB update.

[Q] Is it possible to root after jellybean update WITHOUT unlocking?

I recently bought my new Transformer Infinity and like an idiot I updated to jellybean without thinking if I wanted to root first.
I've tried several different ways but I can't get my TF700t to root after updating so that leads me to ask if I must unlock before rooting after jellybean?
I've tried downgrading and that is to say I've put the 9.4.5.30 update in my root of the microsd card and when I go to recovery boot i just get the little guy on his back with a red triangle and black exlamation mark.
I realize unlocking will void my warranty which I am a little hesitant, though I never purchased any warranty with my tf700t but i think i can do so now.
I tried following this post:
Thanks for the reply, but i've been working on this for the past couple of hrs and my issue is solved. i'm currently back at 4.1.1 Jellybean again and Root Checker has verified that root is in place. the su binary is also present and all apps that need root work properly (Busybox, Titanium Backup, etc). i've also rebooted and rechecked several times to be sure, it say rooted every time now, whereas it didnt before. I managed to do all of this without unlocking the bootloader as well, even though what i've read elsewhere says it is necessary to do so.
I would have agreed with you before on your point that OTA updates are irreversible, and they usually are, but my experience today shows otherwise. however, you are right that each OTA will probably make it harder to reroot or stay rooted. you're also right that factory reset only wipes data but not firmware, which i just recently figured out today before you posted. i used the "about tablet" section in settings both before and after my steps below to verify that i had indeed downgraded/upgraded firmware/Android versions from JB to ICS and vice versa.
here are the steps i took, in sequential order, so that maybe anyone else with my issue can benefit. i cant gaurantee it will work for everyone:
1. downgraded from 4.1.1 JB firmware to "Eee Pad Transformer Pad Infinity TF700T Firmware: V9.4.5.30 Only for US SKU (Android 4.0.3)". This will roll you back from Jellybean to Ice Cream Sandwich. go to support.asus.com, enter TF700T as the model number, and scroll down until you find this, then download it and unzip the zip file to the root of your sdcard (there is a zip file within the downloaded zip, place that at the root, not the downloaded file itself). if you are using a TF700T that is not US-based then download the appropriate file for your region, just make sure that it has .30 in the file name. I read on a forum somewhere that this is the only firmware update for this device that enables downgrading from higher version to 4.0.3, although it's possible that others may work. then power off your device and do a cold boot (hold down left volume and then followed by power button, do this for about 10 seconds. when you get to the desktop/start screen you will see "Safe Mode" in lower left corner, then your device will notify that an update is available. tell it to apply and let it reboot. when it powers back on you should be back at 4.0.3
2. Do a factory reset, this can be done either before or after the step above, but i did it after. i'm not sure if this is necessary , but just to be on the safe side. back-up all important info, apps, etc beforehand
3. I used the method at Simple Guide to Root TF700T Asus Transformer Pad Infinity : Tips For Tab . this guide can also be found at other websites, but the steps are the same and the files/utilities needed are the same as well. just follow the steps. this will not work if you are still at 4.1.1, you will get the error i detailed in my last post.
4. Download Root Checker (to verify root access) and make sure you have the latest Superuser installed from Play (SuperSU may also work but i'm not sure, i'm using the paid version of Superuser Elite). and also get Voodoo OTA RootKeeper (free), this has a function that will allow you to restore root access after upgrading to 4.1.1. Superuser Elite also has a "ota survival" function that does essentially the same, both worked for me (this software isnt free). and get Busybox and a terminal emulator like Better Terminal Emulator or Android Terminal Emulator. i'm not even sure if these last 2/3 are absolutely necessary, but they install essential must-have functions that all root users should have.
5. then use RootKeeper and make a backup of the su binary, or place a checkmark beside the "ota survival" function in Superuser Elite. either will backup the su info so that it can be restored.
6. Next, do a direct OTA upgrade to 4.1.1 JB , either by using the built-in firmware update function, or by manually downloading from the website and updating using the method listed above. Do NOT do a restore to factory backup state after this point (especially after), it will most likely wipe out the backups of su made by RootKeeper/Superuser Elite.
7. after the upgrade is finished you will be back at start screen at at 4.1.1, use Root Checker and it will say you're not rooted. Then use either of the 2 programs ive outlined to restore the su binary from the backup. in SU(E) just uncheck and recheck the OTA Survival box, or in RootKeeper just restore from backup. Then go back to Root Checker after doing either of these, it should say rooted. reboot and recheck to make sure.
8. That's it! just wash, rinse and repeat when the next firmware update is available, hopefully these same steps should work
Also make sure to keep a backup of the su binaries/app from here onwards, otherwise at some point in the future you may lose the ability to simply restore from backup after each OTA Firmware update. you will have to start over from the beginning.
I'm sure someone figured this out already, but i figured i would post anyways.

Where did you get the old ROM from? ASUS isnt hosting it anymore and it HAS TO BE a factory original Firmware signed properly or it will not take. In fact you should see "Signature Match" (or maybe its matched) in the top left corner in recovery.
I'm not saying that message is a guarantee you have the right ROM but its a good sign.
The default warranty is like a year so I wouldnt want to unlock either.

Makes me wonder if they have broken downgrade on the 10_4_4_25 firmware then?! The TF201 had that happen on the first JB update. You could no longer downgrade to ICS.
Edit, Adding that I just downloaded the US 9.4.5.30 from that site you linked to and an MD5 check confirmed it matches the one I have used 3 times.

The link you supplied that has all the firmwares there are several that say 9.4.5.30
The first one is WW, World Wide. You need to make sure you get the correct one for your device. So if you bough retail in the US get the second one that says "US". The firmware will not work if you don't get the correct one.
An easy way to tell what you need is to go to settings and scroll down to "About" on the left. Tap About and on the right half scroll down to "Build Number" My daughters TF201 says JRO03c.US_epad........
So she has the US one and would need the US Firmware.
If you have a US device and tried to apply the WW firmware from what I have read it will fail, won't work.. dead andy. Make sure you have the right firmware for your device.
Please post back your results as I am sure many would be interested if ASUS broke reverting to ICS.

After you download the zip file, first you have to UNZIP the zip file and you're going to see another zip file. Now rename this new zip to EP201_768_SDUPDATE.zip , then copy this to the root of your sdcard, boot into recovery and try again.

The only device I believe you should ever have to root/unlock /jailbreak is the IOS platform. As you probably know, you are extremely limited to any customization with an IOS device. Under the android platform, I find that there are many flavours of customization under the stock setting already. I've ran the TF700T with the latest updates and firmware for the past few months and performance is still optimal ... I also bet that if you had my tablet side by side next to a rooted/unlocked TF700T tablet, you wouldn't be able to tell the difference from a performance perspective. I'm only speaking from a standard user point of view. I can see where a developer may want root access and or someone who wants to learn how to program the OS, create custom ROMS etc., however for the casual user, I'd leave it the way it is.

I guarantee if you unlocked and installed a custom rom you would be blown away with how slow stock is Seriously, how do you know if you haven't done it? Seems like a strange challenge you have set. BTW I don't know one single person who has unlocked and gone to a custom rom who would go back to locked stock because performance is that different. You just don't know it.

A significant reason for increased performance on custom ROMS is that the kernel they use allows for overclocking usually to 1.8GHZ. Just FYI in the interest of full disclosure.
It is not the ONLY reason but a big part of why they look/feel so much faster.

Yes kernel tweaking brings huge benefits but there are plenty of other tweaks that bring the perks as well outside the kernel

I can confirm that 10.4.4.25 did not break the downgrade option. Like others already suggested, make sure you're using the firmware which matches your device (WW/US/etc.) and you should be fine.
I Just got my device tonight from ASUS (RMA due to crashes every 2.5 days on the clock, black lines every few seconds, extremely laggy).
My precious came with 10.4.4.23 and I upgraded it to 10.4.4.25 to check the performance and black lines issue. With 25 it still lags a little but less than 23 and other earlier firmwares. I ran these tests on 23 then on 25:
1. For real life performance (don't care about synthetic benchmarks) I updated all the apps simultaneously. Both firmwares were laggy but 25 was much less than 23.
2. The black line is still there in 25 but much less than 23. I could reproduce it only with the black hole live wallpaper test which is a very good sign as in 23 I reproduced it a couple of times without the black hole live wallpaper.
After these tests I downgraded successfully to 9.4.5.30 (US) in order to root (need that for Avast FW) with no problems at all. Now I will go root it.
Update: Successfully rooted and upgraded back to 10.4.4.25

I downgraded also to clear a few things. After that, I went back in and went to Settings and check updates and nothing show up. How did you upgraded back to the latest version? Can you share your method?
Thank you much.

Are you rooted? If you are you need to use the dlpkgfile incremental upgrade method can be found here http://forum.xda-developers.com/showthread.php?t=1803090

I am rooted now (but still locked). Can I jump directly to 10.4.4.25 using dlpkgfile without doing other middle steps?
Edit: Tried going straight to 10.4.4.25 and failed. No OTA either.

No you can't, you need to upgrade to JB .16, then .18 then you can jump to .25.

OTA. Immediately after restart the tablet started downloading the update automatically... I postponed the update installation and then rooted, installed voodoo, created su backup, temp un-rooted and only then applied the OTA.

Thanks for the update.
Mine did not see any update regarless of multiple checkings performed (this was done before any rooting attempted). I am in the process of dowloading dlpkgfiles and slowly doing the hard way.
Update: After I reflashed back to 9.4.5.30 to root, I went on and started updating using dlpkgfile started with .16, .18, .20, .23, and finally .25. All is good now. However, I had a few errors when going from .16 to .18 due to getting incorrect/wrong dlpkgfile.
Thank you for everyone's help.

Do you have the dlpkgfile (from /cache) for us?

Sorry, /cache is empty
If you take this OTA, it's very likely you will not be able to root or restore root...

Is you firmware version 10.6.1.14.10 now?
Would you be willing to try the Motochopper tool and let us know if it still works?

I've just updated it. It seems one of the bugs Bluebox Security Scanner reported is patched. No idea what else have been changed.

What firmware version are you on? You did confirm having root by running an app that requires it like Titanium Backup?

I don't think motochopper works on this update.

Just installed the update and used OTA Rootkeeper to restore root. Titanium Backup is able to get root and Root Checker Basic shows root is enabled. Attached is a screenshot of the system info after the update.

I think this is a minor update and the driver versions are not as new as the 10.6.1.27.1 update they did for the TF300T. That has wifi on version.7.2.1.50 and Bluetooth on version 11.38.
I won't be using this update as CROMi-X is already beyond it
Sure am glad to hear that it's NOT stopping root, whew!
Sometimes it's good to know you're wrong! :good:

I'm thinking it's time to unlock and flash your ROM. I don't think ASUS will be doing many more updates for the Infinity and the benchmarks on CROMi-X are pretty amazing.:good:

Call me a hopeless romantic, I still think that we will at least receive an Android 4.3 update for our tablet, if not the rumored Key Lime Pie in October. Since the new Infinity is still not out yet, the tf700 should still be the flagship product of ASUS (the new Nexus 7 is a Google device after all). Even HTC with its terrible track record of updating devices has updated its One X to Android 4.2.2, I see no reason why ASUS stops pushing out updates for our tf700.
I hope there wil come some updates
Im on cromi 4.7 now it is usable bevor it was horrible

That's great. Unfortuantely for me, OTA Rootkeeper was unable to restore my root. Motochopper also does not work anymore. Am I screwed?
Asus have blocked the motochopper exploit in this update.
To regain root without unlocking (obviously that's the easy option) is downgrade from the Asus Website, apply root with motochopper, use ota root keeper, temp unroot, upgrade via OTA and reapply root from voodoo ota......

You are the second person (I know of) not able to restore root after that update. It worked for most people.
Can you state step-by-step what you did?
Maybe we can identify why it didn't work for you..
Did you backup or protect root before you updated?

1. While rooted on 4.2.1 (previous build), I started OTA Rootkeeper and verified all checkboxes were checked.
2. Pushed the button to Protect root.
3. Let OTA update run.
4. Started OTA Rootkeeper and pressed Restore root, getting the msgs "root su restored" and "Superuser granted to Voodoo OTA Rootkeeper".
5. When I refresh the status, the "Device rooted" and "Root permission granted" boxes are still unchecked. Root Check also says device is not rooted.
Did I miss a step? I thought it was pretty easy to follow but maybe I thought it was supposed to be too easy?
Oh, if it matters, when I start Rootkeeper, the "/system supports root protection" and "Protected su copy available" boxes are checked.
