[Q] No OS installed

I had installed CM10 on my optimus 2x but I had a problem with the rom so I tried to flash another rom.
By mistake I wiped data, davlik-cache and everything else. So I don't have a backup. When I try to install another rom through TWRP is says that it failed and afterwards it says No OS installed, Are you sure you want to reboot?
Please I only want to return to the original stock rom and upgrade from that to ICS. I found the guide on how to update to ICS so all I'm asking for is how to get out of this No OS installed trouble.
I appreciate alll effort.

Hi Mate dont panic it´s easy to fix have u try any Nflash procedure yet ?

Try Stefans V28G via nflash:
http://forum.xda-developers.com/showthread.php?t=1986097
Direct link: http://d-h.st/PNj
Installation NVFlash version (under Windows): (internal SD will be wiped, /data partiton can be saved and restored with 2nd generation builds)
download the ROM, unpack it with WinRar, 7Zip or similar to any folder you want
take battery out of phone, press VOL + AND VOL - simulataneously, and while doing this plug the phone via USB to your PC
screen of phone remains black, this is normal, but you should hear a sound that you plugged the device. Probably you have to install APX drivers at this point if you are asked. They are included in the latest NVFlash builds. Tutorial on driver installation: http://www.modaco.com/topic/335416-n...-links-active/
assuming that you already installed APX drivers: run the "flash_windows.bat" file in the folder where you extracted the ROM
follow the instructions
That's already it Usually no complications to be feared. Enjoy!

You can connect phone to pc and copy a cm10, don't reboot phone, you must mount mass USB storage. Copy and flash: )

Will try it out
Thanks Domfis and Creison, I will try it out and see what happens. I hope it works :fingers-crossed: out cause I really do not wish to change my phone now that official ICS is out. If I manage to do this I will wait till summer to change my phone. Currently using my old nokia 3310

i suppose you're on the old bootloader? then just use AIO Toolkit ->> http://forum.xda-developers.com/showthread.php?t=2020737
Use Option 4, then you'll get the new bootloader and CWM installed. Afterwards just flash a ICS Rom or CM10(ICS BL) via CWM!

Since data is lost anyway, try running AIO toolkit to reflash the bootloader which also fixes recovery and partitions.

Help, phone won't boot into rom

I have ARHD 7 installed, everything worked fine until i tried to flash the Circlemod
Now the phone is stuck on the boot screen
I can get into bootloader and recovery but my problem is that I don't have a rom on my phone that I can flash
Have I stuffed up my phone?
Any help appreciated

Simply reboot in recovery and flash over the latest ROM from ARHD 7, don't wipe anything simply flash over. All your settings, apps and data will be preserved.
Should do the trick.

Hi, thanks for replying, but I'm not sure what you mean by flash over. I don't have a rom on my phone to flash and I also can't seem to get the mount to work on TWRP so I can't copy a rom to my phone in recovery.

[Q] Problems with custom rom HTC one

I know there are a million posts about this, but I have been through them all trying to follow the guidance because the problems seemed to be the same as others have faced, but I feel differently now....
I unlocked my HTC one, following the htc dev site.
I installed TWRP (I cannot for the life of me get CWM to load into reovery, it only reboots the phone...)
loaded the roms/Super SU onto the SD card.
I know my phone is rooted (or i should assume?) because SuperSU is requiring me to grant access to apps and such.
I flash the custom ROM to the phone, install the package following Revolutions steps. Complete installation, return to fastboot menu. Flash boot.img, clear cache and reboot phone....Phone goes to the HTC Quietly Brilliant screen, with the development message at the bottom and continues to reboot over and over and over from there.
What did I do wrong?
I know pretty much have a phone that wont work because even after restoring it, it is ina boot loop after it fully boots up and nothing is loading correctly. Is there any way to start this from scratch?
Notes:
I tried doing an ADB sideload of Revolution HD.
I do a factory wipe before i load any rom....
Edit:
I have tried multiple ROMS...all the same effect....
I also get the message after installing the ROM from TWRP that "your device is not rooted, swipe to install superSU" so sometimes i swipe it, sometimes i dont...either way same result.
Update #2:
I flashed a ROM called 42ONE....it ended up successfully booting past the HTC screen and is currently updating the android system...However, it will operate for about 2 minutes then the phone reboots like it was before when i tried to restore....what the heck?!?

There is no need to flash the boot.img in fastboot. Just flash the rom from twrp.

Download the rom again (might be a bad download), transfer to your sdcard, do a full wipe, and flash again. Something you flashed has created a conflict.
Edit: That's a Sprint ROM. Do you have a Sprint phone? If you've been flashing GSM roms, that's your problem there.

[Q] need help hope i didnt kill my m7 :(

Last night I was flashing to a new rom.
The phone has had beanstalk 4.4+ on it for quite some time and have never had any issues really.
I was going to give viper 6.1 a shot so I downloaded the zip and put it on my sd card
I rebooted the phone into recovery as I do every time I load a rom and selected wipe to install nee rom option in twrp.
I chose the zip and aroma fired up and installed the new rom and gave me a successful install message and asked to reboot the phone which I did.
Now when I boot the phone it goes straight to the bootloader/fastboot screen and will not perform any functions other than reboot, which it does and goes straight to the bootloader.
pleaseeee help I hope I didn't kill it somehow. It seemed everything was going fine...
Thanks in advance
Jay

... TWRP is the best recovery to flash Viper. If you didnt use that, flash the right TWRP for your variant in fastboot (Sprint in your case and no other), boot into recovery, wipe everything in recovery, run Viper installer, choose wipe all (except SD) and then see if it wakes from the sleep :laugh: ...

there is no need to put a rom as long as you are satisfied with stock rom.... how did you run the ruu .exe file or by fastboot mode???

Got it! Something must have failed. I ran the .exe ruu again and we are up and running! Thanks everyone

[Q] rooted and flashed but unable to flash new rom

Hello!
I have a SGS I9000, which I rooted and flashed with Darky's ROM years ago. I can't really remember how/what I did, but it all worked out fine.
A week ago I tried to factory reset it, but the setup afterwards always crashes, therefore I'd like to flash it again (preferably paranoid android or cyanogenmod).
I have access to the download mode and the recovery mode. So I tried to copy the cyanogenmod zip to my external SD card and rebooted to the recovery mode, to install from zip. But the recovery mode states that there are no files on the external sd card.
Also, when I format the ext. sd card on the phone, it seems to work, but when inspecting the sd card on the computer afterwards, everything is still on there.
Any suggestions how to flash CM or PA on my phone?

Have you tried installing a fresh copy of Gingerbread via ODIN? You can try that. Flash GB, root it and then check if you still have problems.

I was unable to do so, I'll need to check some tutorials on that.
When I tried it, ODIN restarted my phone to download mode and then couldn't find it anymore.

Restarted your phone all of a sudden, without finishing writing your rom ?
