Lenovo manufacture  two best tablets  under the same name of A3300 , called A3300Gv and A3300Hv .A7-30 ,A3300gv is Meditek MT6582 chipset base tablet and A7-30, A3300hv is Mediatek MT 8121M Chipset based tablet.  You must know the difference between A3300gv and A3300hv . Bothtablets are look like same but have huge difference in spec and firmware files. Both tablets support different type of mediatek chipset. 

Few days back got chance to play with this beauty called Lenovo tablet A7-30 ,A3300gv. The actual problem was "adb sideload " error on startup. I tried all the solution beside flashing stock rom but none of them work. Reset tablet will work in most cases but did not work in mine. You must tryreset / hard reset first if your tablet is facing "adb sideload " error , software errors , or stuck on boot logo or forgotten user password. To reset your lenovo tablet there is small hole next to micro card slot. found this image on lenovo forums. 

To hard reset your lenovo tablet turn off tablet , Press volume down button and press power . You will see recovery menu . Select Wipe data . (This will erase all user data from internal storage e.g Contacts , Photos, Videos, Apps) but not the stock apps .In my case none of above mentioned method work so I decided to flash lenovo's firmware . Spending some time I found stock rom 4.4.2 kitkat for lenovo tablet.

These screenshots were taken during flashing of A3300GV but flashing procedure for A3300HV is same as mention. No problem were found during flash(A3300GV).  In some cases (not mine) after flashing, tablet  hang on logo then you need to Hard reset your tab and wait until it  turns on . Beforeflashing tablet you must identify your tablet version (GV or HV) in case of wrong attempt you may result dead tablet.
