Droid Charge Extracted Files


  1. I saw both files but it won’t extract at all. Wizard says extracting then just freezes. Pls Advise?

  2. Your english is atrocious

  3. I have entered download mode but oldin3 will not recognize my charge. Please advise.

  4. I just did the update and it went throught fine…. HOWEVER, now my Corp Sync email will not function. Everything else works fine and is quick. I also reset to factory default and tried agin and it still does not work. I know the settings are correct, (I’m the Exchange Admin). Any advice. Is there a way to roll back?

  5. The update worked perfectly! It wasn’t necessary to reconfigure the APN; 3G, 4G, & WiFi all worked upon booting the phone. Damn this sucker is a lot faster now! Thanks!!

  6. This worked great for me and i didnt have to fiddle with apns the phone just booted and was good to go all radios fired up and the hotspot is flawless. Good work guys. Can someone point me to some ROMS i can flash on this baby? Send me a link please. Btw the quadrant readings after the flas were impessive, they put my EVO to shame…i got 1594.

  7. the only thing i’m worried about is that i started the process direction by direction about half an hour ago and its still the same way and i dont want to unplug it and have my phone be bricked.

  8. instructions were clear and everything works you guys are freaking awesome but let it be clear “to start the download mode you have to press down the entire volume button i believe that was the problem that some were having” otherwise freaking great (follow instructions people)

  9. i have verizon?

  10. The Odin screen says the following…..for about 10 minutes now. Is it still installing?

    Enter CS for MD5..
    Check MD5.. Do not unplug the cable..
    Please wait..
    CI510_VZW_EP1F_ALL_ONE-LTE-CP_REV3_user_CL300919_Rooted_Stock.tar.md5 is valid.
    Checking MD5 finished Sucessfully..
    Leave CS..
    Odin v.3 engine (ID:12)..
    File analysis..

  11. Worked perfect didn’t have to do any apn work

  12. Is this the update that was rumored to be coming directly from Verizon OTA? Seems a bit involved. :)

  13. Well, I figured out it wouldn’t unzip cause I was using Windows 7. Now my problem is getting my droid charge into download mode. I tried it several times the way you explain but it won’t do it. I’ve clicked on the link to figure out how to fix it but the links broken. :(

    • the links are working fine, you can kindly check the same again!

    • If pressing the “Down Volume” button doesn’t work with pulling the battery out, try taking the battery out and connecting the phone via USB (with no battery in the phone), while holding the “Down Volume” button at the same time. This worked for me and I wa able to download this successfully!

  14. Hey, guys. I want to to do this but after I download Gingerbread I try to extract it and it won’t. Says Application not found. I have winwar and isohunter installed on my computer. What am I doing wrong?


  15. i can finallly use my front cam. for skype.

  16. I have not tried this upgrade yet but something really has to be done regarding the Droid’s Mobile Hotspot feature. It is totally the WORST when it comes trying to use this feature. Either you connect to a site for a few seconds or when trying to turn the feature on the Server is not available; it looses connections or just does not connect at all. Bottom line…. IT SUCKS!!! I had a better mobile hotspot connection with T-Moblie. The only thing going for the Droid is it’s screen. The phone cuts off in the middle of conversations and overheats. Hopefully this upgrade with fix the Droid’s issues.

  17. Thanks for posting the detailed instructions. I did the updates to 2 droid charge phones tonight. So easy to do and now both phones had >1400 Quadrant score, much faster than before (~1000 score). No need to to configure the apn & mms. Both 4G and wifi worked smoothly.

    • good to hear that tonymd

    • I had the same experience too. Upgrade was completed in 7 mins, have worked well without any issues since. The only thing, I wished there was some way to do this without losing all your installed apps and having to re-install them again…that was a pain.

  18. Runs amazing. Thank you

  19. Is there a different way to do this on mac or is it all the same? I am trying to download the zip and it is not wanting to download. Or is there another site to download the firmware from?

  20. Hello,

    After executing the “Start” button, the process has run for 30 minutes and has not completed.
    How long should the process run?



  21. Every link on this tutorial goes to a page that indicates “Not Found, Error 404″

  22. The update worked very smoothly.. Thanks! :-)

  23. Thank you, charge is running much smoother now.
    The only thing I would suggest is that you make a note to install the usb drivers off the phone prior to plugging it in when instructed with your tutorial.

    For people reading, (just plug your phone into your computer before messing around with it)

    • I read on another website that the text messaging doesn’t work for sending and spotty on receiving. Is this true on yours?

  24. Will the Netflix app work with this update? or do I still have to root?

  25. thanks pradeep for the update. it worked like a charm!
