  • When i try to flash the recovery image which you have provided, the Rashr app says that the chosen image (7 MB) is too big for your device (partition 0 MB). Should i go ahead and flash or am i doing something incorrect? Pls help πŸ™‚

  • There is two important features on htc desire620G
    1 htc blinkfeed and
    2the most important fearure USB internet( which is avilable on android 4.4 for use internet on phone from pc).
    Will i get these most important features after install custom rom(lolipop,marshmallow) on htc desire 620G.
    Plz tell me about this.

  • When i try pasting the downloaded rom to my phone memory it says “Cannot copy boot.img” What should i do? “Stop copying” or “skip this file” ?

  • Every thing is okay. But your comments confuse me i don’t want brick my phone.
    Bro can you explain
    Chosen image is big
    Download stock rom clean firmware
    Again insatall new recovery. Iam afraid if i face these issues while install rom. There will be my brick phone and i will be not contact for your help.
    So explain little so i install rom without any problems at the spot.

    • See once the Recovery is installed it’s installed for forever so you can install lollipop rom or Marshmallow Rom or be it any ROM with that recovery.
      Incase few people had installed an old recovery so when they were going to install a new ecovery that time they were facing the problem of “Choosen Image is Big”. You can see one of them find a solution by skipping the file size so incase that error persists you can skip the file size and after that i guess rest is crystal clear as I’ve made a big video on it and didn’t skipped a point too. I’m not flying anywhere you can always contact me or do-comment here to get my help πŸ™‚
