[Q] Phone won't boot to system or recovery

So I tried to flash Magnolia X 1.0 coming from MIUI. After I wiped from MIUI and tried to install Magnolia I got an error. No big deal right? So I figured I would reboot recovery ( clockwork mod ) and try again, if it didn't work I could restore MIUI. When I hit reboot recovery I got stuck in a bootloop, from white htc screen to off. It just looks like it is trying to get to recovery but it is not loading it for some reason. So I decided to boot it into hboot and reflash the recovery, or possibly flash twrp. Now my problem is that the computer is not recognizing the phone, so none of my fastboot or adb commands do anything I just get <waiting for device>. Any ideas?

So right after I made the post I was able to get the drivers to reinstall and was able to re flash the recovery. Tried both CWM and TWRP and neither will boot. With TWRP I can get to the recovery splash screen but then it just goes black. Downloading the RUU now and I am going to try to flash that through the bootloader. Other than that I have no othe ideas...anyone else have any?

Got it...had to relock bootloader and run ruu then extract the stock recovery and flash it. Rebooted into recovery let it sit, then it rebooted back to the bootloader. Re-unlocked bootloader then flashed TWRP and it worked fine. Back up and running again.

[Q] noob -- stuck in a boot loop, tried the 2.20 unlock method.

I followed the steps from this thread:
http://forum.xda-developers.com/showthread.php?t=1952038
I successfully unlocked my phone and installed TWRP recovery, but that's as far as I can get. I tried to flash the latest CM10 nightly but hit an error when I run the zip, saying that the MD5 file is not found. I also tried to separately flash the boot.img from the CM10 zip, but it didn't help.
I've cleared my cache and factory wiped (through recovery), but I'm still stuck in the boot loop and can't get to the OS. Please help!!

I think the problem might be that I never actually rooted the phone, despite having unlocked it. Is there a way to root my phone via recovery, since I can't actually boot into it?
I tried to install RebelMod, but i hit an error saying "Unable to mount /data" -- I'm assuming that's because it's unrooted?

you want to root a stock ROM?
flash superuser downloads.noshufou.netdna-cdn.com/superuser/Superuser-3.1.3-arm-signed.zip

update: i managed to flash RebelMod successfully (according to TWRC) by running the zip file, but I'm still stuck in the boot loop even after doing a Factory Reset thru TWRC.
am I missing something?

wait a sec -- I got it working after I flashed the boot.img with fastboot.

Stuck in Fastboot

Okay so I tried to flash cyanogenmod 11 for the first time on this moto G (US). It bootlooped and I tired to reflash it again and it did the same. There was no way of returning to stock because I had not made a backup. So I tried to flash stock in the bootloader and that didn't work. I went into the recovery and it said 'cant mount /sdcard. So go back into the bootloader and format the sdcard and that doesn't work (which I returned to the recovery to see it not working). I go back and flash twrp thinking that recovery would have something to help me flash a new rom and now I don't even have a working recovery. It takes me straight back to the bootloader and every time I flash a recovery it says Mismatched partition size (recovery) and I am unable to boot into it.
I have no clue on what to do at this point and I need help.

also it says invalid "boot image header!" in red letters

Alright thankyou!
I got everything to work again but I still can't flash roms. They just bootloop :S

It could be too big recovery install with fastboot causes problem, every recovery cwm/twrp i tried to install with fastboot fails.

Twrp_MotoG_signed_010814_163615.zip
Download vocoderisms TWRP build, extract "recovery.img" from it.
After you have kitkat installed and working:
Option 1, use TWRP without install:
Boot to bootloader (adb reboot bootloader), boot twrp (fastboot boot recovery.img) and install rom from there.
Option 2, install TWRP (have not tested):
Upload twrp zip to phone (adb push Twrp_MotoG_signed_010814_163615.zip /sdcard/), boot to bootloader (adb reboot bootloader), boot twrp (fastboot boot recovery.img), install Twrp_MotoG_signed_010814_163615.zip.

You do know flashing stock again removes root, so it has to be rerooted again ?

Yes I am very aware and followed through with root with that outcome.

CWM doesn't work it. It boots up (Im used cyanogenmod) the cyanogenmod boot animation but just stays there.

Problem with TWRP -Solved-

Hi all,
I'm trying to get root access on my OPO, so I read some information about the process.
It has CM 11S R38.
* Update recovery unchecked.
* Bootloader unlocked.
Til here everything is OK. The problem starts when I install TWRP or any other custom recovery (I've tried also with Philz CWM). After the installation (via fastboot) it says everything was correct, but when I restart in Recovery the device just "freezes" (actually is the screen which keeps with OPO Logo) and then it becomes to black screen. After this happens I have to force a soft-reset to restart system.
I've tried to roll back to the stock recovery and it works perfectly. But any time I try to flash the custom recovery again, then blackscreen...
I really want to root my device, but I need the custom recovery to install the binaries.
I would be happy if I can bypass the recovery installation, that's not compulsory for me. My plan was indeed flash the binaries and roll back to stock recovery.
Thanks in advance!:good:

i had issue when my recovery was always returned to stock CM recovery
- in developer options there is checkbox "Update CM recovery", have you unchecked that?

Yes, and did not work.
But finally I managed to install Philz Recovery. So it's solved for me. :good:

For me TWRP works only on ColorOS but the OS doesn't boot, with 11S the OS boots but recovery doesn't boot.

S-On, no ROM installed, can't install custom ROM

I unlocked my HTC One Mini then flashed CWM.
I then tried to flash superuser.zip but I couldn't access the sdcard. I read that this was due to the sd not being fat32 so I formatted it in CWM.
This allowed me to put superuser.zip on but I believe it wiped the OS as the SDcard is not external.
So I tried to install CM11 from CWM but I got status (0) and status (7) errors.
I then tried to install a stock ROM and it got halfway through installing update then stopped making any progress so I pressed the power button and it broke CWM. I had to wait for the battery to power down to get back to fastboot.
I followed the advice in this thread (s-on-and-want-to-flash-roms-read-this on androidforums) and tried to use "fastboot boot recovery.img". The advice was to do this and then recovery can access /boot so can write the ROM kernal with S-On. However this just froze the fastboot screen until I held the power button, and then when I restarted the phone it just went to fastboot as did recovery in the bootloader.
I then flashed TWRP and that is where I am now.
I have TWRP in /recovery and the phone is S-On. I haven't tried installing a ROM from TWRP but I imagine the result will be the same as from CWM. As you can probably tell I'm not experienced with this, I successfully installed CM on an HTC desire a couple years ago so I thought this would be easy. I'm guessing I need S-Off to install a ROM, but is it possible to get S-Off without a ROM already installed (with Rumrunner for example)?
Basically I'm stuck, I don't know what to do and any help would be greatly appreciated.
