[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.

[Q] Need urgent help !!! Unbrick, Kernel, Recovery

Hello friends,
I need urgent help !!!
Yesterday one of my very close friend gave me his Note to upgrade to JB (he was on ICS. LF4 if I remember correct)
So I did following :
1. Downloaded couple of Custom ROMs and PhilZ 6.26.6 on to his phone (External SD)
2. Tried to boot into Recovery and voila.....his HOME button is not working. Anyways I booted and adb reboot recovery
3. Then I flashed PhilZ and it flashed successfully. Since I couldn't boot into Recovery without Home button I did Reboot System.
4. Stuck in N7000 Blackscreen and adb shows Device Offline
What I am planning to do now
1. Put device to DOWNLOAD mode through USB JIG
2. Flash Stock JB (Here's 2nd problem - download links are not working for Stock JB at least not Indian one Can somebody with fast internet plz upload it on dev host or Mediafire and share with us. Thanks !!! )
3. Reboot into Recovery and flash PhilZ
4. Flash Custom ROM
Am I doing things right? Is my direction correct?
I would still prefer if I somehow could boot in current OS, put some Custom Recovery and flash Custom ROM. Saving Stock ROM flash path and ODIN.
Plz help and advise !!!!!
Thanks !!!

You installed a kernel that doesn't fit to ICS. So it's no suprise the system doesn't boot. Install an ICS kernel and at least the system should start again.
And after that: give it back to your friend and let him repair the home button first. Don't risk being the fool who ruined his device.
Update: just read again and saw that right now you don't get a connect with adb. So yes, it seems to be the only solution to install an stock rom with Odin. After that I still would give it back for repair.

Can you give me link for safe ICS kernel ? Will this work http://www.mediafire.com/download/32ik5mg6bgg8q1d/PhilZ-cwm6-XXLRK-XEU-3.99.tar.md5
I need to boot in the current OS once to take backup of EFS (I heard JB wiped off EFS of few).
Thanks for coming forward to help !!!

Yes this is an ICS kernel with Philz recovery. Should work and give you the chance to reboot into the OS.
And a backup of EFS is a very good idea (after a repair in Thailand I'm using a developer imei).
Good luck.

Problem coming back to Stock

Dear Community, first of all i want to apologize for my englisch, im from germany.
I have a problem with my HTC cuz im not able to use it anymore. First of all i maybe try to tell u what i have done so far maybe u will find a solution or problem.
First of all i unlocked my bootloader with htc.dev , installed cwm and Android Revolution HD 31.6. After that i gained s-off with the firewater method . All of it was successful.
Like u guess i didnt make an Backup
When i used Arhd i noticed that i didnt seem to stable and i changed the version to 71.1 also for Sense 6.0 . I installed it with cwm and aroma installer i guess and he said that everything was fine and done .
My problem starts at this point cuz when he rebooted the device he stopped at the htc logo and that is the end of the story. Until now nothing else happened , i also retried the installation but with the same result.
After that i read i could go back to a working device when i flash it with stock recovery and rom , I also found a method that worked on several devices in germany .
The author proposed to use a 2.24.161.1 firmware to update the phone and then to flash a stock recovery from the same swisscom device , I followed the instructions but at one point he tells me i should use adb push to move the stock recovery (about 1 GB ) to the backup folder of CWM and then restore the backup the restore my phone.
When i do adb push it says that has been successful but im not able to recover the recovery or to choose the file from sd card when i move it to /sdcard cuz : file not found.
Im really scared that my device is bricked even when it worked before with arhd 31.6 and only the flash to 71.1 make the problems.
i would be really thankful when some of u pro or even of with the solution could help me .

ARHD 71.1 requires TWRP 2.6.3.3 recovery or newer. You can get the latest version TWRP 2.7.1.2 here. Flash this bootloader and then re-install 71.1.

[Q] ROM flash gone wrong. HTC one M7

Hi,
Looking for some help from you guys if possible. I have have been flashing Android HD Roms by Mike1986 for some time now on my HTC One (M7). Last updated to HD-One_91.1 to upgrade to Lollipop. Experienced very poor battery performance so looked to flash back to an earlier Kitkat version. Instead of flashing a previous one, I thought i'd give the Google 6.1_GE a go and see what that was like.
Big problems. Phone kept getting stuck in boot loop - so eventually i decided to wipe the phone and start again. Now when I switch phone on It boots into the start screen for Goggle edition then reboots constantly.
As I wiped the patition, I do not have the option to reinstall even the Lolipop ROM.
My phone wont stay on long enough to copy another ROm over. so Im stuck with a pjone that keeps switiching off before I can do anything with it.
I use TWRP recovery but when i try Factory reset etc, same problem occurs.
How can I get another compatible ROM onto the phone or am I stuck with a knackered phone?
Any advice greatly appreciated.
Thanks in anticipation.

Your phone must be s-off to use this rom like said in the OP. Also said that your phone WILL bootloop if you flash it without having s-off.
Android Revolution HD 6.1
Google Edition
You need S-OFF, otherwise you'll experience boot-loop!
You can't use ART with deodexed custom ROM
You need TRWP 2.6.3.3 custom recovery!

Boot in recovery (twrp), push a rom to your phone using adb push, adb sideload or MTP (MTP only available on newer twrp versions) and then flash the rom.

internal storage inaccessible after firmware flash

hey guys,
i got a problem with my m7. yesterday i flashed the current gpe firmware for the m7 (that one without stock recovery & boot img). i read in the lineage thread that the rom benefits from it in terms of battery endurance, so wanted to give it a try.
the firmware flash process was done without any problems. i entered the recovery (twrp 3.0.0-2) and i wiped everything except usb-otg. twrp showed me that every partition was wiped successfully. i plugged in my usb cable to copy the lineage rom and gapps on the phone, but then i noticed that it somehow didnt work. i checked the internal storage of my phone and noticed that all the files i "successfully" wiped before still were there.
i flashed back to the firmware i had before (7.19.401.51 without modifications etc.) because i hoped it would give me access to the internal storage but unfortunately the problem remained the same.
now i cant copy anything on the phone to flash some new roms and stuff and i cant use it because theres no rom installed.
guys please help me if you can i really appreciate it! (sry for any mistakes im not a native english speaker)

Maybe flash latest version of twrp might help you? https://dl.twrp.me/m7univ/

hey mate,
somehow i managed to bring my phone back to life. i dont know if it has anything to do with the newest twrp but im very happy that it works. thank you for your help!
