Hi, I've been following countless guides on how to root the Nexus S, and I've used countless different root and recovery .img files and none have worked. When I boot the phone, I'm stuck at the Google logo screen and it won't go anywhere from there.
My phone is Wind's Nexus S, GT-i9020... under the battery it says model:GT-9020T
Flash the latest clockwork 3 recovery img and then hold down the volume up and power to get into recovery.
Flash a cyanogen rom or something.
You may need to mount storage through USB in clockwork to copy rom's to it.

Make sure you flash a compatible boot image file. I, too, was stuck on the boot screen until I flashed the right boot image file. Some people swear that the data cable that comes in the box is junk and leads to headaches when trying to root. I have not experienced that, but it's worth a try. Uninstall any Android drivers on your system, and ONLY install the Google provided drivers. That's all I can think of right now, when I was trying to root my phone. I hope this helps.
I needed the Google USB drivers from the SDK and the PDAnet drivers. This was on a Windows 7 laptop.
Its not hard to find the right clockwork 3 img file. I did have to rename the img file from clockworkrecovery3blahblah.img to recovery.img
Once that is done flashing, boot into clockwork recovery and choose to mount the USB storage. Copy a cyanogen rom to the phone then choose to install zip from sdcard in clockwork.

Thanks for the responses. It seems I should not have flashed the boot.img at all. I was able to reset the phone to stock using the zip from this post[/quote], and from there did a correct root using 4002-orange.img for recovery and su-2.3.6.1-ef-signed.zip. There are a lot of bad guides on rooting out there, it took hours of searching and some second luck on stumbling across the right post to reset the phone to factory.

I'm guessing you flashed a boot.img to try and root it?
That's what screwed up.
Take battery out, put it back in, hold volume up and power at the same time to get to Bootloader.
Flash the latest cwm recovery, boot to recovery. mount the internal usb,

First, I knew nothing about rooting any devices up until 2 hours ago. Ever since, I've been trying to set my phone up, but have failed and am extremely miserable at the moment.
So I tried to install the stock rom by using someone else's Nandroid backup, but it says that it "failed to find "cache" partition to mount at "/cache"
I tried to look at different threads and it pointed me to this: http://forum.xda-developers.com/showthread.php?t=988686&highlight=i9023
I read that if I was to "flash_image" that file onto my phone it would allow me to install the stock ROM.
But I can't find anywhere how to do this. At this point, my phone has no ROM on it. If i dont start in recovery, it says stuck at the Google Logo. If it makes any difference I'm on Rogers/ATT device.
Please, help
Is the stock rom zip file installed on SD storage? If so all you need to do is boot into recovery, install from SD card, unzip file (the stock Rom) and then reboot.

unfortunately, there is no stock ROM on the SD card.
I tried installing everything manually.. I installed the android-sdk, got the usb drivers running, and adb works.
but none of the "flashboot" commands work. they all get stuck on "waiting for device" on the command prompt. I was trying to flash a ROM through the computer.
EDIT: fixed all issues.
used PDANet to reinstall all drivers then installed the new 4.0.0.2 clockwork. made it work. thank god.
I was in the same boat as I just bought mine used yesterday.
dl the stock 2.3.4 rom here. it comes as root or non rooted.
http://forum.xda-developers.com/showthread.php?t=1060192&highlight=stock+rom
then flash through recovery...but keep in mind this won't re-lock your bootloader. if you want to re-lock your bootloader, you have to do it via adb.
BTW, you can access your sd storage via recovery.
Edit: Oops didn't read that you had fixed it. Neeeevermind.
I tried to install a new rom after updating TWRP 2.3.0.0. after all was complete it stuck on the boot screen. I then tried with the Nexus Root Toolkit to use a restore from backup. Same problem. I then tried to flash stock and unroot. Same problem. I then tried a number of things through TWRP from backups I had their. Same problem. At present I have no OS and I can only boot into TWRP, turn if off or look at the GOOGLE screen. I have run out of ideas and would appreciate any help offered.
If you have tried everything else (flashing a ROM zip etc.) Then you should flash the factory image from Google.
Don't use the script/batch file as that will wipe your internal storage.
Just flash system and boot.

Sometimes a rom takes a long time to boot for the first time, please be very patient. Also, try wiping everything from /system, and then re install a custom rom from your /sdcard partition. also make sure your roms are for the nexus 7 not galaxy nexus or other similar devices. ONE MORE THING 4.1.2 wont flash with 4.1.1 bootloader.

I know many people hate the talk about toolkits but I was in the same situation and I used Wug's toolkit and it saved me. I downloaded 4.1.2 image directly from Google, as the toolkit only has 4.1.1.
I tried to return to stock on my own and it just went from bad to worse. I would of spent more time trying to fix it on my own but I was on a very tight time constraint. It will unroot your device but it is easy to root again.

THANK YOU the "ONE MORE THING" is all I needed to know for the same problem!
Hi there,
I wanted to flash Carbon ROM to my Nexus 4 and followed the two sets of following instructions (how reliable they are, I don't know):
http://www.android.gs/flash-carbon-aosp-android-4-3-custom-rom-for-google-nexus-4/
http://forum.xda-developers.com/showthread.php?t=2266654
I managed to flash CWM onto my phone and proceeded to create a NANDROID backup (using the "backup to sdcard" option) but got the message "can't mount backup path"
I then flashed TWRP and tried the same but now I get the message: "Unable to mount /data"
I tried wiping the phone (factory reset) to see if I could flash the ROM without backing up and I get the same message: "unable to mount /data"
I am now afraid that I have bricked my device. If I try and boot into the stock ROM it just stalls on the Google logo.
I guess it was stupid of me to jump in like this without much knowledge of what I was doing. However I do believe I did follow the instructions in the above links correctly.
If anyone would be kind enough to spare some time and give me some advice as to how to proceed I would be extremely grateful.
I will obviously post all relevant info or logs if required.
Thanks
2 questions
1) do you still have Twrp installed? If yes, which version?
2) do you have a pc with all necessary Android drivers and a toolkit installed? If no, google for Wug toolkit, install it and be sure you have all needed files in your pc
Then lets try with the 4.3 official factory image. Download it and unzip everything to have all image zips ready.

Hi All
I am in the process of flashing Cyanogenmod 11 onto my TF300T however I am in a world of hurt. First I updated to the latest TWRP (2.6.3 -4.2). When i boot up into TWRP it is asking me for a password which I do not know. If I press Cancel i cannot see any contents of /sdcard. Also if I insert a microSD card, again cannot see any contents. TWRP is telling me there is no operating system installed and if i reboot it just comes straight back into TWRP.
I apologise if this question has already been asked but I just cant figure this one out.
What bootloader version do you have? What helped me was to reboot into the boot loader (using volume down+power, has three options RCK, cold-boot linux, Wipe data [dont ever ever ever wipe data]) and select cold-boot linux (the android guy in the middle) and it would boot back into my ROM. If you cant get in that way, you are going to have to use ADB on your computer and use the "adb reboot-fastboot" command. If you get in, back up your files, because you're at the event horizon of losing all your data. If your bootloader is 10.6.1.8 youre going to need to flash the latest asus stock firmware from their website.

I am using bootloader 10.6.1.3. When I cold boot linux it just continually boots up into TWRP.
Whenever I try to run an ADB command i get "error: device not found". I have installed the android SDK, tried to install the USB drivers but no luck (possible windows 8 issue?).
It doesnt matter if I lose all data on it, i dont keep anything really important on it.
I have rolled back to 2.5.0 TWRP and it still asks me for a password.
I've switched over to my Mac now and have been able to push the CM-11 ROM into the sdcard directory. However when I attempt to flash it, it fails immediately with the log saying.
E:Unable to mount '/system'
E:Unable to mount '/cache'

I had something similar, tried many things but nothing worked so i ended up flashing stock ROM again with fastboot.
If you need help on how to do that just let me know.

Ok this morning I have tried the following:
1. Flashed Scanno's TWRP from the OMNI thread using this command:
> fastboot -i 0x0B05 flash recovery recovery.img
2. Booted up into TWRP, again /sdcard is empty.
3. Pushed the OMNI ROM onto /sdcard using:
> adb push omni-4.4.2-20131218-tf300t-HOMEMADE.zip /sdcard/
4. Went to Install and selected the zip then it immediately fails saying:
Unable to mount '/system'
Am I missing something here? From above i see that i flash 'recovery'. Do I need to flash 'system' with fastboot?
no, but maybe your PITs are corrupt. do you still have an older nandroid backup you could try to restore first?
oh just read that twrp asks for password. is that still the case?
Sent from my GT-I9505 using XDA Premium 4 mobile app
Yep it's still asking me for a password.
What are PITs?
I'm not sure if I have a backup. When in TWRP if I go to restore it can't find any. It's like the whole tablet is wiped. Does this have something to do with not having the ability to mount anything?

Ok, Buster99 I followed your instructions over at this thread and am now back up and running with stock.
http://forum.xda-developers.com/showpost.php?p=44244313&nocache=1&z=9056634965818376
For me to go to KitKat, can I just flash the OMNI ROM now?
EDIT: Nevermind, I am all back up and running, thanks so much for the help, i was getting a bit worried that I had bricked it!
HELP
So I just tried getting cm11 on my tf300t, i installed TWRP 2.5 and rooted my device, everything went well. I then did a factory reset and wiped cashe. I tried installing then cm11 zip file with no success. I get the message that it failed. And now im on a device with no ROM to boot into and no working ROM to flash on the device.
Since there is a SD card slot on the device, would it be possible to put another ROM on there and then flashing that?
Please help me!

in order to install CM11, you need a special TWRP modded for KK: http://forum.xda-developers.com/showpost.php?p=48508679&postcount=7
You can copy a CM11 nightly and the TWRP onto a SD card and flash from there, or use fastboot.

Hello, i have a similar problem, i wanted to install CM11 on my TF300T, i downloaded the latest version of TWRP from their site for the tablet, installed via Fastboot and everything seems to be ok, when i try to flash it (via CM OTA) it ask me for the password and it didn´t mount any data, but when i reboot the tablet it just keep loading twrp and i can't get to fastboot nor adb nor APX, so i have no idea on how to restore or boot back to the OS, or i just bricked the device?
thanks

When you restart you tablet, and hold the vol down key while rebooting it will give you a bootloader number: 10.6.x.x.x

that's the point, it doesn't do anything, is like i'm not holding or pressing it, it just show the ASUS Logo screen and in the top left it says that the bootloader is unlocked as usual, i don't think is a wardware problem because it was working the last time it booted on Android

Once it goes to recovery, adb will be accessible. Then follow Buster's recovery method.
