[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: )

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] Galaxy S Plus black screen, CWMrecovery says "can't mount...

I'm a noob I know and yes I watched the noob-video. But I need help! Cuz I'm too dump! So please help me
I wanted to update my Galaxy S Plus to the newest CM 10 (Beta 4) (before it was the Beta 3) over the CWM recovery it suddenly says
"symlinks failed"
"error in /sdcard/cm-10-20130324-invendor-beta4-ariesve.zip"
"(Status 7)"
"installation aborted"
so I looked to the CWM recovery and I saw that I don't have the latest version....okay I downloaded the latest one and installed it over the CWM recovery. The same error .... with friends. Now I got when I went into the CWM recovery: (after I tried to wipe data/factory reset or wipe cache)
"E:Can't mount /cache/recovery/log"
"E:Can't open /cache/recovery/log"
"E:Can't mount /cache/recovery/last_log"
"E:Can't open /cache/recovery/last_log"
I tried to restart the phone...black-screen after the samsung cyanogen mod screen.
Okay
So I tried to flash a older firmware "I9001XXKQ7_I9001DBTKP2_I9001XXKPK_HOME.tar.md5" with Odin. I restarted the phone...nope black screen. I installed the newest CWM recovery again and tried to flash again the CM 10. Black-screen. So I tried the old version of the CM which I had before (Beta 3) -> black-screen and still errors in the recovery mode.
I can still go into the download mode and the recovery mode. The charging symbol is not working when i connect it (just the battery but bot moving)
My device:
Samsung Galaxy S Plus
Provider: Vodafone IT
ROM: CM 10 (Beta 3) installed but not working
Kernel: Phenom 3.2 UV (updated after the symlinks failed error)
I hope some genius out there can help me
And sorry for my bad english...I don't use it often (Italy)

what errors does the cwm 5.5.0.4 recovery shows without doing anything?
try to additionally mount system and data partition (see under <mount and storage>)
then click on wipe data/factory reset in the main menu

Hi everybody I'm new.
My situation is exactly the same, I did the same things, got the same problems... got stuck with no solutions yet if not to send it to samsung assistance.
Flashad many other android phones in the past and never had issues like this... it's a nightmare...

try to additionally mount system and data partition (see under <mount and storage>)
then click on wipe data/factory reset in the main menu

Without doing anything the recovery says nothing....just the normal main-screen.
After I mounted system and data I click on wipe data/factory...but then it doesn't do anything. It freezes after "Formatting /data..."
I flashed the FeaMod Recovery v.1.2. based on CWM v5.0.2.7

I already did that too but it didn't work...
I'm gonna go to the samsung assistance in the afternoon... :crying:

Well....Nothing is working...Anyone who could help me? ... Or better us..

If my guide is no use to you as its for i9000 : try this HERE
If that helps you in any way let me know.

I did this already... I flashed it with the newest stock-FW but it doesn't do anything...and the stock-recovery can't make a factory reset. It always freezes....

other things that could be worth a try:
try flashing different recoveries - not only feamod... also cwm,...
for me cwm5.5.0.4 works
look: our wiki-page -> un-brick
if all doesnt help you could try to reset all partitions

I tried already a few recoveries...like the CWM or the TeamWin... How can I reset them? Can you give me a link please? ^^

Flash BroodROM RC 5... flash this multiple times without touching any buttons like repartion etc..
After that, wipe system and data via the recovery provided in the ROM.
Then flash the newest stock FW from samsung..
This solved all my issues multiple times xD

thanks for the reply, but my phone is now finally brocked....it doesn't even start....and I don't have any idea what i can do now...

??
So, now Samsung, no Samsung Galaxy S Plus GT-I9001? No nothing. Not even the soft brick image (see wiki)

a. the phone is booting just fine
i am willing to insall a custom rom and i am not sure if to choise yes fix because i am afraid of problems with the phone after choosing fix:
i dont want the costum rom to install recovey over this recovery and get my recovery corrupted.
and about the root i know i can unroot my phone and use tringle away but with the recovery i dont know how to restore that to the stock
so to sum up before installing a custom rom what to choosie yes or no (on the massage )

Basically the problem is a total lack of understanding regarding rom custom roms etc .
You had better start by reading and understanding the basics before bricking your phone as you don't have a clue .
Basics read first.
http://forum.xda-developers.com/showthread.php?t=2344125
Critical you read the first two posts and understand the difference between I9300 and I9305 .
At a guess the message is due to failure to root .

Stock Recovery being reflashed after a reboot?
There is an auto recovery restore system on stock roms that will reflash the Stock Recovery on a Stock Rom. If the restore files are renamed then CWM Recovery should not be overwritten after a reboot.
You need to be rooted and then delete or rename the following files:
Quote:
/system/recovery-from-boot.p
/system/etc/install-recovery.sh

Why don't you start from the beginning as per the faqs and guides root flash recovery flash custom rom whatever .
I simply do not understand your posts they make little sense and i cannot work out where you are in the flashing process .
EG
Stock Recovery being reflashed after a reboot?
>>> No it is not flashed .
There is an auto recovery restore system on stock roms that will reflash the Stock Recovery on a Stock Rom
>> Their is no auto recovery stock includes stock recovery.
If the restore files are renamed then CWM Recovery should not be overwritten after a reboot.
>> no idea at all what this is and you do not rename files .
Are you sure you are in the right forum ?? this is I9305 forum .
You have an EFS backup ???

Use Odin to flash recovery, or heimdall if you are running Linux.
You can already copy or download su zip ( in case you want stock rooted.) or custom ROM to your sdcard, so that you have it ready for flashing.

Use this method:
http://forum.xda-developers.com/showthread.php?t=1942150
Why use this Root Method? Well the main reasons are:
- You have a complete Odin Flashable ROM Package.
- No Insecure Kernels are used or required.
- You can flash these packages on Non-Rooted devices
- The Binary Flash Counter will NOT increase when flashing these ROM Packages.
- The Red Exclamation Mark will NOT appear at boot up.
- And finally, you only have to flash one file in Odin and you have a complete firmware including Root Permissions.

[Q] Bootlop after failed wiping data [Solved]

Hi guys, i need your help..
I was tried to install a custom ROM and i use CWM v6 to install it (i'm on stock ROM | JB 4.3 | FW .205 | locked bootloader | recovery installed : CWM & TWRP), first step i format the /system and is successfull, then the next step wipe data/factory reset but i get stuck process on:
--- wiping data ---
clear /data done.
clear /cache...........
I don't know why, but i've been waiting for 20 minutes and still stuck like that than i decides to turning off the phone with tiny button at bottom of battery (not power button), i turn on the phone again and then i've got bootlop ( what.... where is my recovery ) i didn't noticed the recovery still in there because there is no LED notify when i turn on the phone, just SONY logo :crying:
Is that happen because wiping data didn't completed and causing my recovery also gone ?
So what should i do ? can i get the phone back again ? I have the stock ROM backup on my sd card and on my laptop because before i try to install a custom ROM, i've created current ROM backup with CWM.

You wiped /system so your recoveries are gone.
On older Recoveries using the wipe to install new rom can take ages so just leave it and eventually it will finish, latest version of Philz (in Bagyusz/Nexus ROMs) seems to fix this issue.
Use DSSMEX triple recovery and use philz not cwm as its a much nicer recovery (but the clean still takes ages as its an older version)
Use flashtool to flash stock rom and start from scratch to re-install custom rom.

You have bootloop because your phone is essentially empty of any OS or recoveries.
Flashtool to stock, find dssmex triple recovery and install that in stock when rooted, load into Philz, clean to install a new ROM and then just wait, it will take a while usually dont worry unless it takes over an hour.
Then flash the custom ROM of choice.

Can I know what Custom ROM are you trying to install?
Sometimes wiping could take time, and I am not sure why. If happens again in the future, just let it be.
As you are using LBL, I am unable to elaborate nor understand how recovery has gone. (WARNING: FOREIGN LANGUAGE) Recoveries for LBL are stored in the ramdisk OR the FOTAkernel. This is due to the fact that Xperia SP does not has an exclusive "recovery" partition in the rootfs. I dont know if wiping data would trash them.
You can easily recover your phone by flashing a stock ftf. You may follow this guide: http://forum.xda-developers.com/showpost.php?p=56717587&postcount=4

Thanks for your explanation sir :good:
Flashtool to stock means i need .ftf file to restore the stock rom ? is it possible to restore stock rom through nandroid backup file that i've created using cwm ?

Well, the problem is solved. My phone back again and a custom rom has been installed.
