[Q] No more Operating System on device

I recently rooted my galaxy tab 2 P3110 with Odin and CWM recovery 6011 and i seemed to have wiped the stock android os as i cannot boot into it anymote - the Tablet automically boots into CWM all the time
Then when i try to install Slimrom or CM installer to flash and install a new OS but i getting an error 7 - unverified file so i cannot put any Os back on the device
Can anyone help?

Sounds like you flashed the wrong recovery, possible that you installed the p3100 recovery.
Try reflashing the recovery.

Flashing KK ROMs on outdated recovery will get you a status 7 error. Grab the latest (I'd go with TWRP as CWM support will be ending soon) version from here...http://forum.xda-developers.com/showthread.php?t=2548257 update to the latest one you like (CWM is 6.0.5.0) Load up a ROM and give it a go. I put all my ROMs on an external card to be safe. Maybe do that and then just install from such.
p,s. CM installer never works, I dont think our tabs are compatible with it. At least I've never got it to work.But, you dont need it anyways.

[Q] Custom recovery and custom rom troubles

Hello xda members,
i have a a31 Majestic tab 110n (i know bad choice), it has never been updated and the stock sofware sucks really bad. So i tried to install a custom recovery and ROM, Cm 10.2 from Christian Troy. I tried to flash from zip. sdcard TWRP for ONDA v792 but the touch didn't work. so i tried to install latest CWM and didnt get trough either. I couldnt flash with odin and phoenix cause locked bootloader. I ask you if there is a custom recovery and rom i can flash.
I hope i can get some answer here. i would really appreciate it. if there is any developer that can develope a compatible recovery i would pay him for sure.

Hi.
I did not flash the ROM that you mentioned (Primo-S)!
Which recovery do you use to flash the custom rom? I had some issues with CWMR and had to switch to TWRP ... to flash CM 11 on the Desire-S.
Regards.

Hi.
After rooting the phone (with CMWR) I flashed TWRP recovery to the HTC Desire S (TWRP-saga-2.8.7.0-unofficial.img)
After booting in recovery I installed CM 11 (cm-11-20150702-UNOFFICIAL-XNG3C-saga.zip)
Due to the limited space on the HTC Desire S I installed only a reduced set of GAPPS afterwards (gapps-444-base-20150818-1-signed.zip plus some Gapps afterwards).

[Help] Flashed the wrong rom on..the wrong model

Hi everyone,
I made a "little" mistake and i'm coming for some help
I have the Asus Memopad HD 7. I made some research on the web to flash a new rom and I found this threat about lineage OS. I followed the tutorial and almost everything works fine..
...
...until now ! I'm trying to make my tab' stock rom again but it appears that I flashed a wrong kernel (because the threat is about the Asus Memopad 7, not the "HD" version )
I have acces to the recovery (flashing a rom doens't work "error 255") and fastboot (flashing another recovery doens't work "bad kernel").
Could you please help me to make it stock again ?
Thanks !

Error 7 usually means the ROM is not intended for your specific model number or there is an error with updater script in the ROM zip.
