Hello, I think my NS is bricked...
I was in recovery, I Unmounted /SDcard, I remounted /sdcard. I went to reboot system, but that's not what happened. Instead I'm in fastboot.
At the top, it says In red caps: FASTBOOT MODE - NO BOOT OR RECOVERY IMG.
My volume buttons and power button aren't working. I cant do anything. I'm not good with ADB, but is there a solution there? I can't get into my phone at all, I can only stay in fastboot. Can anyone help?
Your phone does not have a boot , therefore cannot start a ROM, and it does not have a recovery. It says that it is in fastboot, therefore it can listen to your pc and download a recovery from it.
You probably used fastboot to unlock your boot loader.
You therefore have to find a thread with instruction to unlock the boot loader. It will give you instruction and files for downloading a recovery image to your phone.
Good luck

I dunno about that, I'll try it, but when plugged in whilst in fastboot, my computer doesnt recognize anything.
you need to install the drivers on your PC, then suggest you install CWM, root, flash a rom of your choice.
This is a good place to start
http://nexusshacks.com/nexus-s-root/how-to-root-nexus-s-or-nexus-s-4g-on-ics-or-gingerbread/
I have the drivers installed properly, I rooted my phone a few months back..
nope, if your phone is not recognised you need to reinstall the drivers, happens all the time...just try it
Try this... Just "play along" until you get to the "unlock bootloader" option.
Once you get all that done, it should install CWM and everything for you. I have not tried it in your exact scenario; however, I have used variations of this tool for ages.

Bricked ?
if your stuck in fast boot mode , just flash original image from here :- https://dl.google.com/dl/android/aosp/soju-jro03e-factory-c9f5a67d.tgz , using fastboot flash commands , pm me if you need a hand , ok
Start with this get ADB working right.
http://wiki.cyanogenmod.com/wiki/Howto:_Install_the_Android_SDK
Then this guide to flash CWM
http://www.intomobile.com/2012/01/30/install-clockworkmod-touch-recovery-galaxy-nexus-and-nexus-s/
After getting CWM to work, press volume up +power to go to Fastboot then choose recovery to enter CWM
if all works well you can flash any ROM you want
Good luck

Hi,
After a serious software problems (crashed with 4.0.3 OTA update) i managed install a ROM, but my screentouch doesnt respond to my touch. The screen and all buttons function very well but i cant put the pin because touchscreen doenst work.
Could it be Software or is definitely Hardware?
Could be software. Have you tried flashing a new ROM (and appropriately wiping beforehand)?
Have you tried to access to the recovery ? Some recoveries use the touchscreen as the TWRP for example

I can acess to recovery sometimes
When it fails push it in PC via fastboot.
Now i cant enter in recovery and cant connect via usb to flash another recovery
I'm screwed!
I cant get into recovery, when i pressed appears a android toy whith a warning sine.
I cant connect to PC, when in bootloader and connect to PC, in bottom appears "fastboot fails invalid command".
I´ve installed a stock rom 2.3.6 and the touch screen doesn´t work to iniciate the phone. Try to install franco kernell but it´s the same situation.
When i can connect the phone to PC i´ve try´de 3 different custom roms and none works.
Going to warranty.
Looks like your touchscreen may have just given up. Everything else is normal, you probably don't have fastboot/adb setup properly and that warning sign is the stock recovery. I'd sort out fastboot and lock the bootloader before sending it in. Also, if you don't have a backup of your sdcard you can mount it through a custom recovery (use "fastboot boot recovery.img").

I´ve format SD card and have nothing inside.
"I'd sort out fastboot and lock the bootloader before sending it in"
How can i do that?
Remember that i cant access to recovery or turn on by computer.
Read the rooting guide or check out NexusSHacks.com, all the info you'll need.
How are you "pushing" recoverys via fastboot if you don't have fast boot set up properly?
Anyways. Speaking of fastboot. Get the official fastboot images for your phone and flash them all. If you still have issues with the screen its a hardware problem.
You should make a full backup and then flash the official factory images (ICS 4.0.4), made for your hardware version, through fastboot. You can find the exact version beneath your battery on a sticker.
If the problem persists after this, it's most likely a HW problem.
If the mobile is not recognized in bootloader / fastboot mode, then connect it to a Linux PC, and then post here the output of the following commands (as root):
Code:
tail /var/log/messages

I have an interesting problem:
I have a tf300t curently running JRO03C.ww_epad-10.4.2.17-20121018
I ended up here after an unsuccessful flash with twrp. Tried to recover my back up with no joy. At this time it would only boot twrp recovery, finally flashed stock via micro sdcard and got it to boot again! Only I had no root anymore, so I tried to boot into recovery and there was none. So next I tried to boot into bootloader and when I select fastboot, the tablet says starting "starting fastboot download protocol" but after nothing else happens. ADB looses it, and it just stops right there.
The good news is that I can still use the tablet, it boots and everything works fine but I have no root. I have searched and read and searched and read. I don't know if the reflash flashes the bootloader but that didn't seam to have any effect. If anybody could point me in the right direction I would sure appriciate the help.
there is a way on the TWRP instructions using terminal when you are in system

No when I try to flash recovery it says waiting for device and nothing ever happens.
I seamed to have got it. I down graded to 10.4.2.9 and back to 13. plugged it to the computer and this time it installed drivers and that time I was able to flash recovery. I don't know what happened and it was probably something that I was doing wrong. But just incase that is what did the trick and it helps someone else, i wanted to be sure and follow up.
Hi,
I tried to install a ROM but it got stuck on the white screen with the HTC logo. I tried to do factory reset but it gets stuck again. I don't have clockwork recovery, and I rooted my phone using adb and ace recovery, which is not on my phone. I only temporarily used it to flash my rom, stupid I know. :-/ When I connect my phone to the PC it is not being recognized. I tried putting the PD98IMG.zip file on my sd card but it just says that it the image is incorrect. Is there anything I can do? Is this fixable?

I just went through some similar stuff. What type of computer are you using? PC/Mac? Are you using the original cable? What troubleshooting steps for connectivity have you done? Different cable? USB port?
Can you access the bootloader screen when you pull the battery and reboot while holding the volume button down and holding the power button? By accident, I found that the phone and PC will communicate with each other when "Fastboot" is selected on the bootloader screen (you should hear a connection chime and it should change to "Fastboot USB") except I could only get fastboot commands to work. The good news is that should be enough to flash a boot or whatever else you need to get back in business.

Hi, Thanks for the reply.I am using windows 7. I downloaded the drivers for HTC, and I am using a data cable and the USB port in the back of my computer, nearest the mother board. I do see "Fastboot USB" on the phone but when i type in the command prompt "adb devices" I get nothing.

That's great you're getting the fastboot usb message! As long as you're not using a hub or some other usb extender, any functioning usb port on the pc will do. Again, I learned this by accident (ie the hard way) and found that in this mode, only fastboot commands will work, not adb. (on a side note, and others should correct me here, adb and fastboot work together when the phone is rebooted normally or in recovery but not in the bootloader screen)
Great test for connection: fastboot devices (if you get anything else except a serial # with fastboot after it, then close the cmd window, unplug, and pull battery/reboot to bootloader), fastboot reboot-bootloader. Once it reboots back into the bootloader screen, make sure you press the power button while fastboot is selected and you should again hear the chime and see fastboot usb come up. This is your phone saying it's ready to accept your fastboot commands.
Do let us know how it works.

As far as I know, fastboot only works when your phone is in fastboot mode. ADB works in recovery or system.

Flash a rooted stock ROM from recovery. Whether you have root is in your system partition. Whether your bootloader is unlocked is in your bootloader. Whether you have a custom recovery is in your recovery partition. Three separate things.

I'm guessing that you're trying to flash a PD98IMG.zip or a RUU. You need an actual stock rooted ROM, probably from here on the forum. Or just flash Android Revolution HD, an optimized rooted stock ROM, also from here on the forum in the development section. For more specific steps read the Ace Think Tank linked in my signature.

Dear friends,
I have this problem: I got a brand new TCL S720 and the Google Play did not work, being a known rom issue. So, before doing anything, I've managed to make a backup of it's original rom with MTK Droid tools whichI supose it did it well. Then I've tried to install a CWM recovery to try a custom rom for it. The CWM recovery seemed to install succesfully but I didn't manage to install the new rom. If I remember well, it stucked on boot logo. Then tried to revert at it's original stock recovery, managed to have the phone back as it was in initial state, but doing more tries, It remained stucked on boot logo. The problem is that my computer doesn't recognise it anymore, when I connect it to USB it tries to install MTP usb driver but even before the driver was installed well, now it refuse to install, like the driver is not good or the proper driver doesn't exist. So the only thing I can do is to boot on stock recovery but even I tried to copy the original rom update.zip on external SD and to flash the phone using install update from sd card in recovery mode, It doesn't find the external sd card. So I'm stuck here, the computer doesn't detect the phone to try flashing it with SP flash tool or MTK Droid tool, and I also can't flash it from sd card. Have you any idea how to make it work again?
Thanks in advance.
Hi! My Oneplus One is stuck in boot (the oneplus logo).
I can get into fastboot but not recovery. I have followed some softbrick guides and the problem that I have is that even after flashing twrp as recovery I cant get into recovery. when I try to start it to recovery (volume up + power) I only get to the oneplus logo again. and when I use "fastboot boot twrp.img" the backlight comes on but the fastboot image stays, fastboot doesnt recognize it from this point so i have to restart it into fastboot mode again.
i have tried to flash the factory images, but nothing seems to change.
I dont know what to do, pls help..
After flashing recovery from fastboot, do NOT issue the reboot command. Press and hold the power button till phone powers off. If you issue the reboot command from fastboot, custom recovery will be lost. Also, don't know which twrp version you are trying to flash, but I would suggest flashing 2.8.6.0 first, then after you know you can get into recovery, you can flash another version.
Additionally, to boot to recovery you have to hold
volume down + power
volume up + power brings you to fastboot
Last but not least,
fastboot boot twrp.img
does not boot the recovery which is on your device, but the recovery image which is located inside your fastboot folder on your pc.

Ok, I did not know that the reboot command removes the custom recovery. Im almost certain that i've tried just powering down and trying recovery before too tho.
I was trying to flash twrp 3.0.0.0 so i'll try 2.8.6.0 asap

oops, i ofcourse ment that i try to get to recovery by volume down+power, and i know fastboot boot twrp.img boots from the .img on the computer, i just think its peculiar that nothing happens.
nothing has really happend after this, so i still need help.
summary: bump
I don't really get what you say. Perhaps i don't experiences before. @kenboyles72 is correct, official ROM may delete custom recovery (you can change the setting). Then @AcmE85 gives you an option, but it does not work.
Here is my option:
1. download any custom rom. The best idea is as minimum MB as possible. (Flash ROM directly from your PC)
2. flash your recovery, do NOT reboot. (fastboot flash recovery rec.img)
3. flash your ROM. (fastboot flash zip rom.zip)
Let's see if this would help you.
I had some issues a while back, where I was caught in a bootloop and flashing another rom. So I followed this guide, https://www.reddit.com/r/oneplus/comments/31sf0x/guide_how_to_return_from_oxygenos_to_stock_cm11s . You can skip flashing the userdata.img to keep all data on sdcard. Also you can substitute flashing twrp recovery img for stock recovery. I myself went ahead and flashed all stock just to make sure everything booted correctly, then went into dev options and disabled update cm recovery, booted back to fastboot and flashed twrp 2.8.6.0. Evey thing worked like a charm.
Flasing stock rom did not affect anything noticeably.. phone is still stuck in boot/fastboot
Just to confirm, have you tried either/both of these:
http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541
http://forum.xda-developers.com/oneplus-one/general/guide-unbrick-oneplus-one-t3013732
I have followed the return to stock guide, but not the unbrick, since my phone is softbricked, not hardbricked.
I have followed this guide tho, to no avail https://m.reddit.com/r/oneplus/wiki/devices/one/brickguide
the strange thing is that i didnt cause this. The phone started randomly overheating and one time it just never booted up.
I haven't really touched this tablet in a while, but i wanted to start using it again. I was running BlissPop. It was slow, and kept giving me an error when it was trying to update, so I decided to try a different ROM. So I downloaded the lineageOS ROM and tried to flash it.
However, TWRP kept giving me an error when I tried to flash the ROM. I don't remember exactly what the error was.
So, I thought that I needed to update TWRP. I tried through the "Official TWRP" app, but after doing so I was unable to boot into recovery mode at all. I could still get to the bootloader, but when I tried to select recovery mode it would give me an error and dump me back out to the bootloader menu.
I tried installing twrp through "TWRP Manager" app, but it just says "something went wrong"
I tried doing this using ADB. I connected the tablet, enabled USB debugging. If i do the ">adb devices" command, I can see the tablet. Then I did >adb reboot bootloader - which works, it reboots the device into the bootloader. But then I try and flash recovery and nothing happens, it just says <waiting for device>. And if I do > fastboot devices it doesn't list any devices.
If I reboot to the bootloader and select "Recovery Mode' i just get the nvidia boot logo and it stays there forever.
I don't know what else to try at this point.
I think I could get this to work if I could just get fastboot to recognize my device, but I'm not sure what's preventing that from happening.

Did you set:
Allow oem unlock in dev opt.
Fastboot protocol into BL?
Twrp app & manager need root to work.
Just flash the latest stock ROM first, lineageos requires having latest firmware.
I wrote a little guide not long ago about that (obviously, you can skip the F2FS steps if you don't need F2FS and just flash ROM after flashing latest TWRP)

thanks for the help, i'll try and work through this soon.

I had seen your thread, and was intending on following it. nice post. 2 quick questions though
1) this is a shield tablet that was supposed to be remotely bricked by nvidia after the warranty claim. Will that happen if I flash the official recovery ROM?
2) how would I even flash that rom if I can't get recovery mode to work in trwp?
I think the root problem that I'm having is that I can't seem to connect to the device via fastboot (i'm sure i used the wrong terminology somehow)
edit: well I downloaded the USB driver for the shield tablet from nvidia, and i was able to install that (rather than the google usb driver). Fastboot finally recognized my device after that. I'm trying to flash the recovery now, but it doesn't seem to be doing anything, just been stuck on this screen for a while now: https://i.imgur.com/BUwj3Hx.png guess I'll continue to wait a while.
edit 2: well, finally got TWRP to flash over fastboot (https://i.imgur.com/tV1DqDv.png) however I still can't enter recovery mode. I just get the nvidia boot logo and then nothing happens. TWRP manager still says i don't have it installed either.
i'm about ready to give up on this... i've spent like 6 hours on this crap already and I feel like I keep getting further away from it.

edit 2: well, finally got TWRP to flash over fastboot (https://i.imgur.com/tV1DqDv.png) however I still can't enter recovery mode. I just get the nvidia boot logo and then nothing happens. TWRP manager still says i don't have it installed either.
i'm about ready to give up on this... i've spent like 6 hours on this crap already and I feel like I keep getting further away from it.

Okay so I'm guessing you have stock ROM.
To flash TWRP you have to enter fastboot mode (vol down + power I believe) and flash the twrp image with fastboot flash recovery twrp.img (rename the shield tablet twrp to just twrp.img and place it into your easy adb and fastboot folder)
And DON'T reboot into OS, rather use your volume buttons to navigate to "restart to recovery" or just use hardware keys again directly from TWRP (vol up + power).
Good luck

Agreed. This is probably what is happening (as described on the TWRP webpage here:
Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install.
Alternately, immediately rooting (flash SuperSU or Magisk) right after flashing TWRP, will prevent TWRP from being replaced with stock recovery.
Although the inconsistent fastboot connection, and how much trouble you had flashing TWRP initially, is a bit worrisome. Try using a different cable (maybe the one you are using is not connecting well?) try another USB port on the computer, and don't use a USB hub (connect direct to the PC).
Well, like they say: persistence is key. I kept pushing and trying new things until eventually.... I bricked the device. No, not really, it's working great now on LineageOS.
Thanks again to everyone who helped me out :good:. I'm still not sure exactly what caused TWRP to stop working on my device, however following this guide helped me fix it: https://forum.xda-developers.com/shield-tablet/help/help-stuck-nvidia-boot-screen-t3076462
The "flash-all.bat" restored everything to stock (including the recovery mode) and after that I was able to flash the latest TWRP and install Lineage.
