[Q] Flashed boot.img, did a reboot, but phone keeps restarting after splashscreen

I'm trying to load the CM ROM to my HTC One S device. I was able to unlock and root the device. Next, I flashed the boot.img (fastboot flash boot.img) from the ROM zip file to the device and restarted it (cm-10.1-20130304-EXPERIMENTAL-ville-M2). Now my device just cycles through the HTC splash screen with the red letters "this build is for development purposes only..." -> Android Splash Screen. Phone does not properly boot up. I think I missed a step in the flashing process. Any ideas on how to proceed?

fastboot flash boot boot.img
just in case you typed it the way you wrote in your post.
what recovery are you using? what version?
maybe try twrp 2.3.3
get into bootloader and flash again, go to recovery do a full wipe and install the cm zip again.

Sorry, the command I used was "fastboot flash boot boot.img" The CM boot.img definitely got written to the device. I missed the step of copying the ROM to a folder on my device. I wasn't clear on this step since I'm not sure how to view folders on the device. Is there a way to load the ROM from my PC instead of copying the files to the device first?
I'm using TWRP 2.6.0.0. I'm also not clear on the back up portion since there is no SD card on this device. Is it possible to perform a backup? I thought I did one during the initial step, but now that I'm trying to restore, I don't see a backup available.

yes, the "sd card" is there as a partition or whatever. But it works the same way. Backups do work.
So in twrp mount the sd card (usb storage, whatever twrp calls it), then you can transfer the rom to your phone from your computer. Then just wipe your caches and install zip.
You can get into recovery from your bootloader, hold volume down and press power (don't hold)

Thanks for clarifying. I successfully loaded the ROM on my device.

My workflow stopped at the same spot, screen is locked in the HTC logo and the warning about the build being development purpose only, but trying again to get into bootloader and the phone doesn't load it up, it just turns off and nothing else happens

Was your battery too low?
Hopefully you can get into bootloader, that's pretty important to fix anything.
someone could correct me, but can't you hold power down until the buttons flash, then hold both power and volume down button until bootloader starts.

So you are trying to get into recovery. When you go into the bootloader, you choose recovery and it doesn't work.
you could go back to bootloader, fastboot usb.
from there open a command terminal on your computer. From your fastboot folder press shift and right mouse click <open command terminal here>
type
fastboot erase cache
then you can press power button to select hboot, then volume down to recovery.
You could try to flash a different recovery if that doesnt work. Make sure you are using the correct recovery for your device. S4 version or the S3 international type devices.

mmm yeah tried what you said, and still got stuck in "entering recovery".
I used eyeballer recovery which is the one CM recommends on their wiki
EDIT: My HBOOT says VilleC2 in that case S3 recovery would be the correct one?
EDIT: Yep found the correct recovery back in business, many thanks Tivofool

[Q] flashed wrong boot.img. [solved]

My mistake, my bad mistake, I was trying to gain root and to flash a CM rom, but after first successfull flash of a boot.img with fastboot, I have tried to flash the rom with TWRP but my device was recognized as a wrong model, so I couldn't to flash the rom (in settings it was recognized correctly as D6603), so I decided to flash another boot.img, but it was for Lollipop instead Kitkat and now I can't put my device in flash mode or in fastboot mode to flash the correct boot.img or a fw, turning on the Z3 the display lights on and seems to have a bootloop, I see the splashscreen, but nothing else.
Is there a way to recover it?
Thanks in advance.

Hold volume down and connect USB will take u to fastboot. Tried to flash a FTF yet?

Yes, I've tried with volume down (flash mode) and volume up (fastboot mode), nothing seems to works.....
EDIT: wow! now I was able to reboot it into recovery, but I don't know if it's useful, it's the Cyanogen recovery.
EDIT2: Yeaaahhh, from recovery I could reboot it into fastboot mode and to flash the correct boot.img, the device is recovered, I've tried one hour before, sorry to bother the community.

[Q] Getting back recovery and root after OTA to CM12s

Hello,
I have recived the OTA today and I flashed it and now I dont have a custom recovery and root. What steps do I need to take to get those things back? I have tried to use this guide https://forums.oneplus.net/threads/...oader-install-custom-recovery-and-root.64487/ but after flashing recovery.img through ADB I still have normal CM recovery.

Go to Developer Options in Settings and disable the "update CM recovery" option.
Transmitted via Bacon

It has been disabled the whole time

Ok. So you say you're flashing the recovery through adb but that's impossible so I'm assuming you're flashing with fastboot, right?

I'm not really good in those names.. I have isnerted a screenshot from this program.

Looks ok. Where are you getting the recovery from? Did you rename it to "recovery.img" for a reason?
Transmitted via Bacon

I've got that file from TWRP website and I renamed it to recovery.img. I have succesfully booted into this recovery with a command "fastboot boot recovery.img" which allowed me to flash root and xposed form it but after rebooting the phone the old recovery remains...

I have the same problem. Flash TWRP says it's flashed OK, but when I reboot to recovery it's still stock.

Same situation here...this solution isn't working for me, same problem, always Cyanogen based recovery...

After flashing new recovery, when you go to reboot, hold down Vol-Down and Power before it boots into the OS and it should load the new recovery. Had this problem myself earlier today, if you let it boot to the OS, it flashes back the CM recovery.

It works! I think it because of the dev settings into CM12S which force the recovery to be CM12S' one.
Thanks

I'm having the same problem, can someone go over start to finish how they fixed this issue?

What worked for me
I previously had TWRP installed, wiped and did the C12S flash but didn't flash SuperSu before rebooting. This removed TWRP and brought me to Cynogen Recovery whenever going into recovery mode (Vol Dwn + Power). This also removed the root from my phone. To fix this took some digging and I came up with the following solutions as long as you had TWRP installed at one point. If not then unlock your boot loader and re install. I named my TWRP File Recovery just to keep things simple, but whatever your TWRP Filename is put that in at #5.
1) Enter Fastboot Mode (Vol Up + Power)
2) On your computer open command prompt (Ctrl R)
3) Plug your phone in
4) Type the following minus the quotes
"cd desktop/android-sdk-windows/platform-tools"
5) fastboot boot recovery.img
This will boot your TWRP, you can then go to flash your SuperSu file and you're done!

im having this issue too : /

Unbrickable tf300t

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.

Can't flash TWRP [Oxygen OS & OnePlus recovery]

I am on Oxygen OS (2.1.4) with OnePlus recovery and am trying to install TWRP recovery without any success.
I followed the fastboot method rather than the stupid toolkit
All the steps go through easily with success messages but every time after completion I boot into recovery, it still is OnePlus Recovery and not TWRP
Note - There's not option called "Update Cyanogen recovery" to uncheck under developer options because as I said, I'm on OnePlus Recovery
P.S - I have a Mac and followed the tutorial via terminal under the path ~/Library/Android/sdk/platform-tools

You claimed all the steps went through successfully which can only mean you fastboot flashed TWRP (fastboot flash recovery recovery.img) and it showed success but if you reboot to recovery its still Oxygen recovery.
Your wording was misleading. My advise only applies if the flash was successful.

Do not reboot after flashing twrp, you have to shutdown, off the phone after flashing twrp...If you reboot, stock recovery will overwrite twrp..All you have to do is very simple, fastboot twrp, off the phone, enter twrp ( power + volume down) and done!...twrp will forever be your recovery..
