lost root after factory reset

While troubleshooting another issue I did a factory reset. I'm running stock JB. I rooted on ICS and kept root via ota root keeper. Anyway, after the factory reset none of my apps can gain root. /system/bin/su is there. I tried installing Superuser app and SuperSU but that didn't help.
What am I doing wrong?
Thanks.

You had to have installed SuperSU and Superuser prior to updating to Jelly Bean. If you had the SuperSU binary, and backed up your root with Voodoo OTA Rootkeeper prior to updating.... you will be able to fully restore your root access after the Jelly Bean update.
If you only had Superuser prior to updating and backed up using Voodoo, you will most likely have lost your root, like several other TF300T users.

I did have super user installed before the JB update. Oh well I think my other issue is hardware so.I'm going to get a replacement tablet anyway.

I said SuperSU, not just Superuser. You need to have both installed... at least that's what I've heard works perfectly so far.

My issue is different than what you linked to. I updated to JB and restored root just fine. That's what that thread is about. My issue is a factory reset killed root

Oh, okay, sorry I misread. Doh!
Yeah, you're right, factory reset shouldn't break root. That is strange!

yes a factory reset usually kills root, at least that's how i unroot my old-broken nook tablet 6 months ago.

I have a thread on this too. Basically you can't use the debugfs method anymore because you can't symlink /data/local anymore. So if you restore normally after the job update, you're fine, but if you do a wipe, it doesn't work anymore despite such being in /system/xbin.
I'm going to assume we'll just have to wait for these awesome devs to come up with another exploit. Either that or unlock the bootloader and go the custom ROM route.

I guess right now bootloader is unlocked.
Because I didn't use unlock app from Asus, but I can get access to fastboot usb download protocol.
if you press vol down + power you'll get acces to a lot of functionality. Maybe it can help to get root back
PS: I lost my root too... And right now I'm trying to get it back.

No bootloader is not unlocked. I think that is a result of the update. I have not tried it but perhaps it could be used to flash .30 back on it? Care to try?

I can't try it right now, because I need to leave from the office.
But, I assume that we use fastboot -i 0x0B05 flash recovery twrp.blob this function to update recovery because bootloader is now accessible
I can try it only tomorrow morning. Maybe some else can try it faster and write here the result.

I don't know about the exact command structure but I did see a sample listing of command formats, similar to what you'd see if you typed adb with no arguments.

[Q] Looking to fix these problems

So I own an Asus TF300T and I'm using Jelly Bean [Rooted 4.1.1]
Here are my current problem's.
1) I am unable to get CWM to work on it as it will install correctly through Fastboot but when I reboot into Recovery it will hang t the RCK screen. I don't know how to fix this as I've tried a few different recovery images, all of which were CWM.
2) When transferring via Bluetooth to my Nexus 7 the TF300T will reboot for some reason... same thing happens when I'm sending files from my N7 to the TF300T. Any idea's as to why this would be happening?
3) I am unable to reset my device to stock, has anyone else had this problem?
4) I have minor time's where the device will just reboot because of what I assume to be the processor taking on to much of a load from the Android OS. Is there a fix for this problem?
Any answer's or solution's would be helpful. Every time I find what I think to be a fix doesn't work...

1) What bootloader are you running from? [Edit: Sorry, forgot you mentioned you are on Jelly Bean there -- You will need to make sure the CWM is JB compatible (again look at the link I posted here for the CWM JB Recovery)] If you are on the new JB bootloader you have to have CWM recovery that recognizes this. I don't use CWM on my TF300, but you might try HERE to find info on that. I do know that TWRP version 2.2.1 and higher have a JB bootloader version. You can find it from their site HERE.
2) No clue on the bluetooth. I don't use the bluetooth transfer so I haven't ever tried this out.
3) By "reset device to stock" do you mean the Factory Wipe Data option from the boot menu, or something else? Please explain and I'll do what I can to assist.
4) I've had my device reboot a time or two for no reason, but I don't know enough about debugging things in the software to know what's going on.

Hey nate, thx for the reply, but by "Reset to Stock" I mean ou download the original stock image and re-flash the original firmware...

Being that you are already on the Jelly Bean bootloader, you cannot flash any firmware to working condition that is not a Jelly Bean bootloader. This means that you can only flash 10.4.2.9 or 10.4.2.13 firmware versions. Anything else won't boot on the JB Bootloader. Also, the ZIP file you might download from the ASUS site requires it to be unzipped first. There is another zip file inside of the downloaded file that is used for the actual flashing process.
-Nate

Yup I know that part...
Just confused as to the process of getting it done...
I have some experience in flashing new firmware but with the TF300T I'm so confused xD

There isn't anything "rocket-sciencey" to flashing on the TF300. If you have ever done any type of ROM flashing, the returning to Stock is the exact same way, just using the stock firmware file downloaded from ASUS.com. Find the firmware you want to load, download and unzip the file to a YY_epad-X.X.X.X_2012xxxx.zip where the YY is your location code (US more than likely) and the X.X.X.X is the version of the firmware you are loading up. The xxxx should say "user" if memory serves correct. Put it on your MicroSD and flash it like you would any normal custom ROM. Wipe Data, Wipe Cache, Flash ROM, Wipe Dalvik, Reboot. I'd be happy to put together a more fluid tutorial on this if needed.
-Nate

I didn't see anything from US so I tried WW.....
Sent from my Nexus 7 using xda app-developers app

If you go to asus.com and click on United States, then go to the Tablets and the TF300 download section the only ones available should say US. But I think WW should work, no guarantees though.

I'll try that today thx...
I'll post back later

Problems flashing custom recovery

I have a strange problem. A while ago I successfully unlocked my infinity. That was before the jb update. I also successfully flashed custom recoveries and several roms. Didn't ran into any problems. When the official jb update came out, I restored original recovery and flashed a stock ics Rom, and after that successfully applied the jb update. The second update .30 also went smooth. I used the update file from Asus servers. Now I want to flash a custom recovery again in order to flash cleanrom. In adb I see my device and I can reboot with fastboot and stuff. So I think my drivers are ok. However as soon as I start to flash recovery.img it just says sending recovery and that's it. It just hangs there. Nothing happens. I tried everything, from changing usb ports and uninstalling drivers... It just can't send the recovery img. I use Scott's script to flash the recovery.blob. any ideas?

I can't use it because it needs root, and as long as I don't have a custom recovery I'm unable to root my stock jellybean Rom. Or is there already another way to root?

Are you saying you can not get TWRP or CWM installed ? or are you saying you do have one installed but no root ?
If it is the latter then can't you just flash a custom rom that has root built in ( like Baked ) then go back to twrp and now with root you can wipe and flash stock. ? I am sorry if I am miss understanding your question. But at least you get a free 'bump'

He said he has no root (why he couldn't use Goomanger) and he can't flash recovery.

Thats correct, i am trying to get custom recovery, after that root is no problem.
Edit: i just installed a clean windows 8 installation. So no old drivers left behind or other weird stuff. I put my transformer in fastboot mode, driver is automatically installed, i see it under device manager. Stillno luck.... it hangs saying sending recovery.... no error messages. My previous attempt was under win7.

Glenner, did you make sure you have the img file in the same folder as you fastboot/adb command files?

If it says "sending recovery", I'd assume that it found the local file.
I don't use Windows, but I always read about driver issues in Windows. Maybe the auto-installed driver is wrong? Does "fastboot devices" return question marks or nothing?

i'm happy to report that finally it worked! seemed something strange with drivers/USB ports after all. Despite i already changed USB ports under my win 7 installation, i tried it again under win8, and suddenly it worked. I didn't reinstall the drivers or something, all went automatically. So the strange issues are driver issues for sure. Anyway, currently happy running cleanrom 2.3
thanks for all your suggestions and thinking along.....

problems rooting tf300t

hi i tried rooting my tf300t using this method http://forum.xda-developers.com/showthread.php?p=26435786#post26435786 i got to the part where you have to flash the root signed.zip and i did flash it but then when i press reboot system now it asks me "root access possibly lost. Fix? THIS CAN NOT BE UNDONE" then it gives me options no , yes-fix root (/system/xbin/su), ******go back*****. anyone know what i should do. iv tried all 3 then going into root checker it says you do not have proper root access but i do have super user in my apps list and titanium backup will not work.
anybody know what to do?

Try using twrp recovery for flashing instead of cwm.
Sent from my ASUS Transformer Pad TF300T using xda app-developers app

I agree. TWRP is the way to go. Also, if you are going to flash a custom ROM that is already rooted, don't even worry about rooting it with the root zip because it's not needed. The rooted ROM will take care of rooting it for you.

thanks
thanks twrp worked.

Thanks, got it rooted. But now I installed an app that gives me a black screen of death when it boots (LCD MODDER). I am int he process right now of recovering a backup.

Hi,
This happened to me too, I'm assuming that you are trying to do the process manually or with a 1-click utility?
For me it worked with the 1-click utility that I found in the droidrzr forum's.

CWM Recovery
These are the 2 utilities,
The first one is only to install CWM
http://www.droidrzr.com/index.php/t...-twrp-recovery-1-click-ver3-updated-52913-v5/
This worked perfect for me after failing with other methods.
This other utility is the "Matt Utility" you should download it, it's a big file (610 mbytes) but it's good to have it in your computer just in case.
