Thanks a lot for the advise it helped and it solved my problem.
It's the only way to do it. I tried many ways to figure out the issue and just couldn't. Lol
I've got the same problem.
I flashed my L preview ROM via TWRP and view the files on my sdcard through TWRP. So how do I flash flash-all bat

The moron is trolling. Don't feed the troll. There is no batch file. Did you read the FAQ in the OP for the L Dev Preview?
Yes there is a flash all bat file. Direct from Google

hi there, as the title says im in real deep trouble. To start off i rooted my phone which want a problem, but then i tried installing a rom which wasnt a problem either. The problem is i didn't know i had to install GAPPS so i wiped my phone and tried again. The stupid thing was that i completely wiped the whole phone i have no OS and my recovery doesn't work anymore. I cant access my phone through my computer as it tells me to format my phone. I cant even access recovery anymore my phone just goes in a cycle of rebooting. PLEASE I BEG YOU HELP ME ! X'(

Can you go into Bootloader/Fastboot? (Volume Down + Power)
EDIT: Read your other thread. You need to flash a stock recovery. You can do that via fastboot. Flash a stock recovery, format SD card, then flash a custom recovery again and you should be good to go.
Process of flashing any recovery is easy. Refer to the method in my signature, you just need to follow the RECOVERY FLASHING PART ONLY.
Other necessary info is also available.

No problem.
Fastboot drivers ok?
where did you get from and then put recovery.img?
also check name of the whateverRecovery.img file to be the same as "recovery.img"

Great. Now you have a stock recovery. Just format the SD Card from recovery and the SD should be good.
Afterwards, you can flash any custom recovery and mess around with flashing ROMs etc.

Download This. Open the zip file with 7-Zip or WinRAR, go to firmware.zip, extract recovery.img.
Then flash the recovery in the same way. This is the stock recovery and not TWRP.
I am assuming your phone to be S3 and updated to Jellybean already.

Hey there,
I've bricked my OneS after I edited my build.prop.
What I did:
One week ago, I've unlocked my phone via HTCdev and than I flashed TWRP and this rom:
http://forum.xda-developers.com/htc-one-s/development/rom-oneplus-one-stock-rom-cm11s-one-s-t2869703
Yesterday, I noticed that my computer does not find my mobile phone and adb is not working.
I thought that this is caused by the build.prop edits which I've done with the Pimp My Rom App so I deleted the modified build.prop file and added the stock file of the rom. After that I tried to restart my OneS but now only the screen htc boot animation with the red text appears and the mobile phone does not boot anymore but I have still axcess to the bootloader and the recovery. Adb doesn't work but fastboot works.
What should I do? I've found this solution: http://forum.xda-developers.com/showthread.php?t=1630459
But do you think it will work with my problem, because my adb already haven't worked before the brick.
Sorry for my bad english!
Edit: The content of the system folder is deleted
Do you haven't any ideas?:crying:

Hello recently I changed a setting on my phone's build.prop file. I have a ZTE Warp Sync on Android 4.4.2. I believe I changed the dalvik.vm.heapzise=8m(or similar to that). I didn't mean to put 8 in but wanted 148. I have the default build.prop file but can only access the recovery mode. So I am wondering if anyone knows how to make a signed update.zip because everyone I make seems to fail. Also if I try doing any adb commands it says "error:closed." Thank you for any help or advice you can supply it is all appreciated.

I believe I've found a rom but I would prefer to not. It needs TWRP installed which in recovery mode I'm unsure how to do. The reason I would like to not flash a rom is because I've got 400 pictures or so from my Italy trip and would like to save them. Other than that I don't need anything on the device.
I don't think flashing a stock rom will delete your photos because they shouldn't touch the sdcard partition of the phone. At least it's been like that on the numerous phones I've flashed to and from stock
