How to fix USB init failed RSPL\RSPL.cpp (723) on NAND Android installation?

There were several readers who had issue during NAND Android installation. They faced Error Description: USB init failed ~ Info: .\RSPL\RSPL.cpp (723) issue. Basically, this happens on Windows XP which uses ActiveSync.

How to fix USB init failed RSPL\RSPL.cpp (723) on NAND Android installation?

  1. Load Android Flasher mode.
  2. Connect USB cable from PC to phone.
  3. You should see MAGLDR with ‘Wait USB…USB’.
  4. Go to control panel and then ActiveSync.
  5. Uncheck allow USB connections.
  6. Then execute DAF.

This should solve USB init failed RSPL\RSPL.cpp (723) issue for Windows XP users…

    scratch my previous post on MAGDLR – i got past this and then got stuck at this point but Jayce this has done the trick – hopefully android is installing successfully!
    Right i better get ready for work hehe

    • clive

      aha a little patience paid off and it all worked with only a few mins to dash out of the door and get to work – on got there on time but in all the kerfuffle i left my lunch at home!

      All is well now so far

  • mughees

    i tried doing this, but it does not connect to USB on magldr screen on my device.. and its giving the same error on android bootloader

    • Using Windows XP?

      • jason

        it doesn’t work on xp????

        • Yes but with above tweak.

          • jason

            Dear Jayce

            Can you please make a video of how can we install on xp.. i been trying a lot I couldn’t figure it out. So can you please make of video of you doing it…
            I have this usb problem.. My Rom 2.10.531.1 Radio What do i do First… Hope You can Help me…. Thank you

            • Sorry, I don’t have Windows XP.

              • jason

                Then Can you please show it in window 7 please..

                • Windows 7 does not use ActiveSync. And I don’t have this issue as I cannot duplicate it on Windows 7.

                  • Frank

                    I have it on Windows 7 as well. Went to Windows Mobile Device Center and unchecken Allow USB connections when the screen said Wait USB…USB, but DAF still gave the same error on the same line.

                    • Frank

                      FOUND IT.

                      This post helped me:

                      I placed the two files, EnterBootLoader.exe and rapitool.exe, in the same directory and it worked. As always, don’t forget to uncheck Allow USB connection as well as to run DAF with administrator rights. HAPPINESS! ANDROID!

                    • nadim

                      plz can u tell me in details how to place those 2 files in the same category ! plz its my last step i wanna try the android .. thx 🙂

    Hi Jayce,

    I was asking for help for “SD Kernel open failed” error… search through all forum… tried all that is posted but none working…… finally I found the problem…

    <> !!!

    I bought a new SD card (8G Class 4 Kingston ) as a backup to try NAND Android, for some reason, it cannot be recognized by MAGDLR…. So I plugged in my old SD Card ( provided with the phone when I purchased ) WALAH !! My ClockmodRecover Works !!!

    Tried many different to reformat my new SD card, but still cannot be recognized by MAGDLR… so use it as my backup…. any clue ??

    • I am using Kingston 4GB Class 4 card. No issue for me. Try to delete all partition on your SD card. Then create only 1 FAT32.

      By the way, you do have initrd.gz and zImage files in your SD card, right? Else ClockworkMod Recovery won’t be loaded.

  • JOSÉ

    1 more request: could you please help me with a tutorial for how to install 2.2 froyo on my sisters HTC ARIA unlock help please and also the roms

    • Sorry, no idea on HTC Aria.

  • Tolu

    • DarkForces Team Android Flasher

  • jason

    i cant find the ActiveSync in the control panel.. am using window 7.??

    • Windows 7 is using Windows Mobile Device Center. Not ActiveSync.

  • YEN LY

    I cannot get past the Dark forces team screen and it keep restarting please HELP !!!!

    • May I know what have you done previously? Need more information in order to help you.

      • Prakrut

        dude i installed WPH 7 according to the instructions given by u…. I too cannot go past the Dark forces team screen n it keeps restarting…. when i tried to install android again, flasher shows:
        USB init failed RSPL\RSPL.cpp

        • Did above guide help?

          • Prakrut

            no.. unchecked usb from windows mobile device center 6.1..

            • This guide does not mean for Windows Vista / 7 with WMDC.

  • gijs

    please help how can i do this i hate it can you make a movie to help us ? Load Android Flasher mode how can i load it? please send me fast an answer with mail or here please !

  • Alex

    Still facing the “”RSPL.cpp (723)”” problem after I did the steps above. Using Windows Vista, unchecked the allow USB connections in the Windows Mobile Device Center in Control Panel. But same error shown in DFT Android Flasher windows.

    • Hmm… This should not happening in Windows Vista. Try to reboot Windows and plug in again USB cable.

      • Alex

        Thanks for ur prompt reply.
        Tried rebooting several times and even updating the USB driver (which always show UP TO DATE). But problem still exist.

        This problem happened only after I flash Task29. Before this, I was having Android on my HD2 but the freezing problem keep happening.

        From other forums… seems like this problem shouldn’t be happening on Vista platform. But unfortunately I got it. 🙁

  • Alex G

    this will sound pretty stupid, as i manged to do this last month before restoring the phone, but i can’t find activesync in the control panel (and im using xp)

    • Install it again if cannot find.

  • I’m in the process of installing this awesome ROM now. I will let you know how it turns out. If I follow your instructions to the letter and it works out, I would like to know if you have a donations link.

    One more thing, on the CMYLXGO’S Topia HD Android ROM I was not able to factory reset the device no matter what method I tried. I was hoping if I am able to perform a factory reset on this NAND Android ROM…short of having to reflash the ROM of course lol.

    Hit me back whenever you can and thanks in advance.

  • Paul

    How come when I try to put recovery on the sd card it wipes android from my phone?
    plus i am getting cannot load error

    • Sorry, I don’t understand what had you done…

  • Dmitry

    On windows 7 run DAF flasher as Administrator

  • Have a ?

    Whenever I flash a new ROM on the HTC hd2 do I have to give it root access every time I do this? Reason why I’m asking is because a certain app called My Backup Pro requires root access to restore not only my apps and data but also restores the data stored on those apps as well.

    Awaiting for your response and thanx again for that awesome “stock” Android ROM!

    • Yes for applications that need root access.

  • fabricio

    i did all of the steps shown above but error keeps on happening plzz reply fast and give me sum suggestions

    • What is the error? And what are you trying to install?

      • Tarek

        and before that I had the same error msg , although I did all above steps ,. I even installed win 7, dlded win mobile center., and unchecked usb boxs, yet still stuck on waiting usb … usb .
        problem is that it is my first time to install ROM. and I can’t get back to my previous HTC OS win 6.5. so I’m stuck with the black screen of MAGLDR , plzzzzzzzzzzzzzzzzzz help

        • What had you installed on your phone until this issue came out?

  • MaheshPolkam

    Im using Windows Vista, Im administrator and in Active Sync (Windows Mobile Devicecentre) I have unticked the box: Allow usb connections. It still does not work, i still get the same error. Btw it shows SD kernel open failed.

      • Sjoerd89

        • Are you using MAGLDR v1.11 or v1.13 now?

          • Alan

            I am using ( aMAGLDR V1.11 )
            and another problem that i have can’t put the device to ( ClockworkMod Recovery ) , because yesterday i did this procedure ( EXT3 partition on SD card ) i thought it would help …but i made the problem much more complicated …sorry for disturbing you JAYCE …but you are my only hope to get my HTC HD2 working again …thanks

            • Use v1.13. v1.11 has issue to copy big size file. Please follow the guide that I gave you…

              • Alan

                i can’t connect the device to PC there is no connection , i have tried to fix it through this link :

                without success !

                • So you are using ActiceSync with Windows XP? And still can’t make it to work?

                  • Alan

                    I am using VISTA with WINDOWS MOBILE DEVICE CENTER..

    you should be the next Steve Jobs 😉


    • Alan

      i have a qustion why i have only 235 MB internal storage ? it suppost to be 512 MB am i right?

      is there any way to increas it?


      • Android OS system installed on internal memory. So it takes some space. Use A2SD+ Android ROM with EXT3 partition on SD card to have more space.

        • Alan

          i have ( 1024 ext partition ) and ( ClockworkMod Recovery v1.3 250 MB ) n i want to use ( Sensation XL NAND Android A2SD+ Zip ROM for HTC HD2)

          the requirements are ( 210 MB CWM partition layout and 1 GB of EXT3 partition ) as you mentioned in the related link

          so how to get 1 GB of EXT3 partition ? because when i try there are only those choice (128M, 256M, 512M, 1024M, 2048M or 4096M)


          • 1024M == 1GB.
