I recently rooted my phone (T-Mobile US Nexus S) and installed the 4.0.3 OTA update from this thread, but now I cannot access any Google apps or get root access on any of the apps that require it.

Ok! first download : http://www.4shared.com/zip/XG506hyV/icsroot-fastboot-recovey.html
just unpack, connect your device and click run.bat.....Good luck!
I ran the .bat, but I get an error saying "Device already rooted", but it is still not recognized as rooted by SuperUser.
Alternatively, is it possible to completely wipe the phone of everything (including root) so I can start over with a fresh phone?
Of course you can, and might be the best idea if you don't mind doing it.
Make sure you have the latest CWM recovery on your phone, download the FULL ROM from this thread (i'm not american so i don't know exactly, but from what i know yours is the I9020T, so get that ROM) and copy it to the SDCard. Now go into recovery, wipe system/data and dalvik cache, then flash the ROM.
Do make sure you have the right ROM though. This will get you 100% fresh and untouched 4.0.3. You can probably clear out any non-personal folders on the sdcard too, but that shouldn't do any harm anyway.
After this, use the attached file from this thread to root, and feel free to update root/superuser.
Actually, that's what I did...I can't use CWM recovery because its displaying an error of no root. So how do I wipe this or fix CWM?
Is your boot loader unlocked? And are you trying to flash cwm through fastboot?

My bootloader is apparently unlocked and I'm trying to flash through fastboot.
Are you sure the following is satisfied:
-open padlock and google logo on boot
-fastboot (on phone) says "bootloader status: unlocked" or something of the like
-you are using: "fastboot flash recovery "C:\path\to\recovery.img""
-you are using the above command while connected to the PC via USB (with working drivers) and that you are in fastboot mode on the phone (turn off phone --> hold Vol. Up then hold Power TOGETHER for about 2 seconds, should give you reboot and recovery options)
It is necessary to be in the bootloader/fastboot interface on the phone when you run the command. Hopefully it was something simple that i said above, otherwise i'm completely lost.
1. Yes
2. Yes
3. I didn't use that method to root...
4. I'll try that.
3 is just flashing recovery, that is the code u type into cmd/terminal to reflash the recovery img. It isn't rooting the phone. 4 is how to get into the mode on the phone to use the command.
Its a bit confusing at first but makes much more sense once you do it one or two times.
Where do I go to get the recovery image?
The latest ClockWorkMod Recovery can be found on this page. Just scroll down to Nexus S and download 5.0.2.0 crespo .img. Then just direct fastboot to the folder you have it saved in while using the "fastboot flash recovery C:\path\to\recovery.img" command.
Ok. I've tried this, but in command prompt, I get the following error:
C:\Users\Bruce>fastboot flash recovery C:\Users\Bruce\Downloads\recovery.img
'fastboot' is not recognized as an internal or external command,
operable program or batch file.
Check out this rooting guide, however only go up to step 5 (and do NOT type "fastboot oem unlock", do everything up until that point). This will setup fastboot for you, and setup drivers for your computer. Once this is done, do what you did above and it should work successfully.
Remember to cd (change directory) in cmd to where you unzipped that folder.
There isn't a link...
Sorry, stuffed that up. I fixed the link in my previous post pointing to NexusSHacks - How to Root Nexus S.
It's worked, but when I try to go to the recovery menu, the Google/unlocked padlock screen freezes or it displays an Android with its chest compartment open and a red triangular ! symbol.
I just had a really long reply and managed to lose it by closing the page..
That's the stock bootloader you see there, it probably didnt flash or you rebooted your phone. And make sure that you are flashing the latest CWM you downloaded before.
I flashed the latest CWM, but when I try to go to recovery, my phone freezes at the Google logo with the unlocked padlock.
Have you tried flashing it again, or maybe redownloading the file? And of course making sure it is the NEXUS S version which you are downloading.
Alternatively, try just "fastboot boot recovery.img", replacing recovery.img with the full name and path of cwm.
edit: btw, i'll be gone for an hour or two Bruce so i can answer any more questions/issues when i get back
So, I went through the temp root/S-off routine with WeakSauce and Firewater. Then flashed TWRP over adb. Rebooted to TWRP which asked if I wanted to install SuperSU. I said yes. Rebooted again and came back up in TWRP. Cannot boot to system. Rebooting always takes me back to recovery. Help would be much appreciated!
Oh, and I can also boot to the bootloader, if that helps.
Can you load a rom to the internal memory or on the SD card and then flash and install a new rom?
Same Here

Hey man the same thing happened to me last night, i thought i bricked my phone. I personally dont think the adb method of getting twrp onto the phone is working right now. If someone knows what we are doing wrong plz let us know.
Here is how i fixed it:
1. Put phone into bootloader, put it on fastboot, plug it into computer. You will see it change to "fastboot usb"
2. Download and do this http://forum.xda-developers.com/showthread.php?t=2708686 . To do this go back to your console (terminal or cmd), navigate back to the folder with adb in it, and instead of running the adb commands just type in " fastboot flash boot M8VZWbootInsecure.img ". its easiest to put that boot img in the same folder as adb and fastboot. once that is done you just need to reboot the phone and you are golden.
3. Problem is, when you do this you can no longer get back to your recovery, you get a screen with a red triangle and exclamation mark. I thought I bricked my phone lol.
4. Doing a alternate soft reset will get the phone back to normal android ( hold down power and volume up for 10 secs)
5. to fix it complete use the flashboot method of copying over the recovery onto the phone as shown here http://teamw.in/project/twrp2/226 . This is essentially the same method as in step 2 its just copying over the twrp.img into the recovery section of the phone.
By doing this I was able to get TWRP to work and be able to boot normally to system. Hope this helps.
I think the command you run has something to do with it. "Fastboot flash boot nameofrecovery.img"
Almost certain the command has to be "fastboot flash nameofrecovery.img"

My understanding is that there's two ways of getting into a custom recovery in adb:
1: "fastboot flash recovery nameofrecovery.img" this will flash over the previous recovery whatever that was. It will stick and you get into the new recovery either through hboot or a ROM's advanced power menu.
2: "fastboot boot nameofrecovery.img" this will boot into the recovery temporarily and allow you flash things. Once you reboot from that temp recovery it will boot using whatever kernel (or other .img file in this case) you have flashed into the boot partition.
The syntax for flashing is "fastboot flash <partition> <name-of-file-to-flash-to-that-partition>"
The syntax for booting an image is "fastboot boot <name-of-the-file-to-boot>"
It sounds like you mixed those 2 together and typed " fastboot flash boot nameofrecovery.img" so when you go to boot your phone now the only thing your phone sees to boot is the recovery. That's why your solution is twofold.
1: Flash the kernel to the boot partition: "fastboot flash boot nameofkernel.img" (sometimes these are just named "boot.img"). This will load the Kernel, modules, and ROM so that your phone will boot properly.
2: flash the recovery to the recovery partition: "fastboot flash recovery nameofrecovery.img" This will permanently install your custom recovery so that you can go back into it next time you want to flash ROMs, make/restore backups, etc.
You should be good to go and will likely never make THAT mistake again. Ask me how I know...

I didn't use fastboot load TWRP, I used the adb method shown on TeamWin's project page for the Verizon M8:
***********
Download - ADB / Terminal method:
Download the newest .img file from here
Download the above file. Save it to the root of your /sdcard directly (internal memory only) and rename it to twrp.img
Launch terminal emulator or connect to your computer and open an adb shell, then type the following:
su
dd if=/sdcard/twrp.img of=/dev/block/mmcblk0p43
Then reboot to complete installation.
***********
Thanks all for the other suggestions which I am about to attempt!
I had this happen to me on my Asus EeePad TF101. It seems that TWRP has a bug that prevents it from setting a "boot to system" flag on some devices, causing it to always boot to recovery.
The solution for the TF101 was to reinstall the stock boot image, which appears to align with the instructions already given. Good luck! I know the terrible feeling I had when this happened to my tablet...

Not only did that save my bacon, it had the added benefit of getting me the insecure kernel which I had forgotten about since going through the whole root/S-off/unlock bootloader/insecure kernel routine with my Droid DNA quite a while back.

I was soft bricked and only able to boot into bootloader and recovery and this write up worked for me. Just wanted to say thanks.
Don't use adv/terminal way. It's writing recovery to wrong partition..

The fastboot command to flash your recovery is:
fastboot flash recovery recovery.img
where "recovery.img" is the name of your recovery.img file on your host computer. Don't use "fastboot flash boot recovery.img", as I believe this will flash your boot partition, not the recovery partition.

if you flash to anything but the recovery partition your in some trouble.
same goes for anything like this, make sure you know what that .img is and you trust it. someone could have renamed an hboot to recovery and you end up flashing an hboot to your recovery partition because someone was careless with naming of files.
So I need help... I'm stuck in a bootloader loop. And every time I try to do this fix, terminal keeps telling me this:
error: cannot open 'M8VZWbootInsecure.img'
Any ideas?

This is incorrect.
command is:
fastboot flash recovery nameofrecovery.img
additionally, since you can boot into TWRP, have you tried sideloading a rom?
(in TWRP, go to ADVANCED, click SIDELOAD... i think you need to swipe to activate... then from terminal: adb sideload nameofROM.zip)

Hello everyone!!
After doing a lot of extensive research I finally decided to flash Cyanogenmod 11 on my device (btw it's Moto G XT1033). I followed all the instructions of an xda member. Unfortunately my phone fails after flashing the recovery image. It shows on the cmd prompt that the flashing was successful but everytime I go to recovery mode I am no longer able to access the recovery.img
All I get is a blank screen with occasional blanks, freezes and various types of patterns on the screen. I followed each and every instruction to the letter still I do not know why this is happening. cannot even access the default bootloader now!
Here are the steps I used:
1. Unlock the bootloader
2. Installed adb and fastboot and copied the img file to the adb directory
3. Restarted my phone to the boot menu
4. used the command "fastboot flash recovery recovery.img"
5. got a message that the operation was successful.
However after these steps, I am unable to access the cwm bootmenu. Even the default one is no longer accessible.
Please help!!!:crying::crying:
After flashing recovery, do not reboot the phone. Use the phone's volume buttons to enter fastboot from the phone's fastboot menu.
I would install trwp instead.
I agree on Kannz2's suggestion for TWRP.
AFAIK, the recovery you're trying to flash is closed sourced and is no longer being updated.
Here's a link to TWRP:

Running CO12s with bootloader unlocked. have installed on my windows 7 all necessary sdk tools and packages, on windows command i checked adb version and fastboot all is good.
Now after put device to fastboot mode trying flash TWRP, window command saying that write process ok but still no recovery installed, in developer options I did uncheck recovery update. now if I go to recovery (CO12 recovery) in recovery log I can see that recovery update mode is still "true" how i can turn this off, looks like is blocking access to install custom recovery or is any other solution??

Just had similiar issue, my solution provided by timmaaa:
Flash TWRP again & don't do a normal reboot. After flashing is complete disconnect usb while in fastboot mode, use power + volume down to boot directly into recovery.
Also during command process make sure to use code: fastboot flash recovery recovery.img then skip the fastboot reboot & follow timmaaa's instructions above. Worked for me.
Force reboot to recovery fixed problem
Hello everyone. I am new around here and totally new with android devices. I got my tf300t, installed twrp and flashed to the newest android version. Then my dad suddendly pressed something like restore to the manufactory setting and after that it rebooted and just keep booting with teamwin logo. I can not access twrp recovery mod, it is just in boot loop. I managed to get adb to work, but no fastboot since it does not boot into recovery mode. When I am in adb I can browse the device but the adb reboot bootloader does not work at all. It just hangs there. I can not power off the device because it does not let me, I can not boot into recovery mode with powerbutton and volume down button. After a long power button press it only reboots. I even tried with hard reset button but still the same. Could You please help me somehow? I really need that device for school and I would like to get back into the stock android. Thank you so much for any help.
//edit : I also forget to mention, when I execute adb deviced it shows:
List of devices attached
0123456789ABCDEF recovery
Also the device is unlocked.
Did you tried: adb reboot recovery ?
Did you tried to flash recovery again?
Be sure to use the right recovery for your bootloader. Did you upgraded bootloader to latest ASUS one? One then you're able to flash current recoveries like TWRP like 2.8.5.0 oder 2.8.7.0.
Edit: Also take a look here -> http://droidmodderx.com/prime/?page_id=74
Hello sir. Thank you for answering. I tried adb reboot recovery and it just hangs to be executed... But the tablet is still flashing the teamwin logo. I have the same bootloop as the guy on youtube called Francis Domingo and video called Samsung s5 stuck at TWRP Recovery boot loop (unfortunately I can not add link here).
//edit: Thank you for the link. It look like I have to use option 1a. Is it safe to use that command and I will not make it even more bricked? Thank you so much
//edit2: Now I just realized how to turn off the device to stop from rebooting. I just long pressed power button and up volume button and after the screen went black I kept holding the up volume button. I didn't work with down volume button or if I stopped holding the up volume button after black screen it rebooted again.
//edit3 : Let's say if I get to the twrp mode with option 1a from the link, what do I have to do next to get back to the stock rom (I think it was something like 4.0.3) ? Thank you
What the guy does in 1a is wiping mmcblk0p3.
Afaik mmcblk0p3 is the staging partition. That would be my guess anyway if you had access to fastboot. Usally when you can't boot into recovery, something is wrong in staging. I got the same problem 2 days ago. In this case you usually wipe staging partition via fastboot.
Since you got no fastboot access, you have to try with adb.
After cleaning the staging partition you can flash any recovery you want back again.
The recovery must be flashed to mmcblk0p4 <- 4!!! is the recovery partition. (but you should wipe mmcblk0p3 (3!!!) before)
So I would say, try what solution 1a suggests.
Edit: You can go back to stock android if you want, but there is no reason for this. My advice would be to unlock and root your device, upgrade to latest boot loader (which is done by upgrading to latest stock rom), then flash TWRP 2.8.5.0 and then a useful ROM on top. I'm using the one from timduru which is very nice. You can find it here: http://forum.xda-developers.com/transformer-tf300t/development/rom-t2932783
Thank you for the answer. Could you please write a step by step to get out of brick and to get the stock version, because the newer one I installed was many times slower. The reason why I would like to have step by step is because I don't wanna mess it even more than it is. Thank you so much.
//the stock rom was much more faster than the one I have installed, I mean... the boot time wad unbelievable slow, same with responses and wifi problem. If there is any other faster rom than stock I would be happy but I don't wanna mess with any bugs or slow boot speed and I can not wait minutes until it boots.
Hm, try the Option 1a from the link.
If done, boot into current recovery. Tell me which version and which recovery do you have.
Top on this we can decide what to do to flash a good ROM.
I had the exact same thing happen to me yesterday. Option #1 worked for me.
I did the steps from option #1 and powered down using the volume up + power. I then tried to boot into TWRP recovery, which only reproduced the same issue.
I redid the option #1 steps, and this time powered down using the power + volume down. I powered back up normally, and it rebooted normally into the ROM.
The tablet now works normally, and I can also boot back into TWRP recovery with no issues.
Thanks for the thread and the link.
Thank you so much Catscratch! After I executed both command from option 1a I can get into the screen, where it shows three options: RCK, Android, Wipe Data
In the top left corner, there is written:
Key driver not found.. Booting OS
Android cardhu-user bootloader <1.00 e> released by "WW_epad-10.6.1.27.5-20130902" A03
Starting Fastboot USB download protocol
The tablet can boot into the last ROM but as I said, I would like to have the faster and less buggy rom than this. When I open the settings and click about button there is written: CyanongenMod: 12.1-20150814-NIGHTLY-tf300t and Android version 5.1.1.
If I start RCK it just brings me back to the loop, but now I have fastboot available as it said above and I can list the fastboot devices on computer, which I couldn't before. Should I just execute this command from the computer "fastboot -i 0x0B05 flash system blob" and then "fastboot reboot" or should I download ROM from asus.com/Tablets/ASUS_Transformer_Pad_TF300T/HelpDesk_Download/ -> OS Android -> Firmware and now I don't know which should I choose: If JP or CN or WW or US or TW (Probably US right?). After that should I execute "fastboot -i 0x0B05 flash recovery firmware.img" and then "fastboot reboot" ? Or which ROM should I download to make it even faster and less buggy than stock ROM? Thank you so much again, You saved my tablet
//After I unzipped downloaded US ROM there is no img file. If I remember right the img file is only recovery to reflash the actual one and then when I start the twrp recovery I will select zip file with rom right?
OK, first of all to continue...I assume you got root access. (I think you should have, because you already got CM installed)
Next. Downloads.
Download: https://twrp.me/devices/asusTF300T.html
Also Download ROM+SuperSU: http://forum.xda-developers.com/transformer-tf300t/development/rom-t2932783
And GApps: http://forum.xda-developers.com/android/software/app-minimal-gapps-gapps-lp-20150107-1-t2997368
Push all files to sdcard with "adp push" or in CM. Like you want.
Flash TWRP. (you can skip this step if you already got TWRP 2.8.5.0 or higher version). You don't need latest one.
fastboot -i 0x0b05 flash recovery twrp.img
fastboot reboot
- or -
adb reboot recovery
Now, go into recovery and wipe everything:
- cache
- dalvik
- system
- data
After that flash ZIPs from sdcard. (use "add more zips" option)
1. ROM
2. Gapps
3. SuperSU
Next: Wipe cache and dalvik again (only these two).
Reboot and wait. First boot can take some minutes.
Thank you so much again. Everything work perfectly The rom looks a lot faster than the older one I had there. No issues yet at all. Just awesome. Thank you so much. Really appreciate your kindness and help. You have a nice day !
Thanks. Have fun with your tf300.
