following is a guide to install and update (to 7720) yuki and xbmod rom

not a guide, actually. its my experience. it may not be the case for u!!

this is a way to get 7720 running from the official cabs that yuki/xbmod provided with their rom. no zune needed. u will also skip downloads while updating.

benifit of the method over zune method:
if an update goes wrong, there is a chance that u have to start from the begining. when using zune to update, this means re-downloading all updates (some of them are pretty large). u can also mess up if u experience net problems. but in this method retrying updates (or for some reason if u want to re-install the whole thing again) wont require re-downloading. so its safe from net errors and saves time of downloads. one major advantage is that the procedure in this method is pretty much straight forward (u'll see what i mean).

if u feel the thread is useless, pls let me know. i'll ask a mod to remove it.

note: i am using win7 64bit.

Phase 1: preparation

1. of course, u need magldr installed

2. enable to use last 24 mb of nand from magldr menu

3. clear sdmbr from magldr menu

4. flash v2 rom from yuki/xbmod thread

note: if u have any other wp7 already installed, dont bother goin back to stock. just flash v2 over it.

5. download the "official update cab" from post 3 (bottom) of the yuki/xbmod thread and extract in a folder

note: in the procedure that i followed, i didn't need 2 of the rar files in the zip. these are: 7392-7401.rar and 7661-7720.zip.

6. download "WP7 Update Cab Sender.zip" from post from post 3 (bottom) of the yuki/xbmod thread and extract in another folder.

note: if u use xp then probably u need to download "wp7_cabsender_winxpfix.zip" and extract the contents in the extracted "WP7 Update Cab Sender"

7. download "HD2-7720fix.rar", extract in a seperate folder. install update tool form that folder (version that matches u'r os - x64/x86).

phase 2: the fun part (actual update)

note 1: the basic is that in every step that follows, u put the extracted cabs from a particular update rar file (or zip in 1 case) in the "WP7 Update Cab Sender" folder, send the cabs to the device, when done (u'll know when) delete the cabs from this folder. continue in this way untill all updates are done. u can find all update files in the "official cab updates" folder.

note 2: although u have the updates downloaded, the update procedure requires net connection just to start the procedure. actually nothing is downloaded. i guess it just routin checks if pc is connected to the internet since that's the standard procedure.

note 3: u should set date/time settings to auto.

UPDATE 1: 1 shot and 2 shot updates are available now at XBmod/Yuki thread. if i were u i'd try one of those first. when the following steps were written those files were not there. but since i haven't tried those, i'm keeping my old steps as they definitly worked for me..

UPDATE 2: Now u should use 3 step to go to 7740..

7403 14mn

7720 46mn

7740 3mn



1. extract the cab from 7004-7403.rar file into the "WP7 Update Cab Sender" folder. run the bat file (WP7 Update Cab Sender.bat) in the folder. press "s" to send it to the device. it will prepare the update, restart phone, install update, restart phone and tell u that the update has been done. if error occurs it will let u know about it after restart.

2. following step 1, install all 3 updates, one by one. but remember to clean up the folder before proceeding in each step. follow the order of updates.

note: no need to restart/reset or even disconnect the phone after an update is complete. just move on to the next update. just make sure the date in the calendar tile is displayed right. if not adjust the date.

congrats. u have 7740.. it's that simple now a days :)

6. reset from about screen

enjoy.. its a beatiful ROM

hope it helps.

** please suggest correction if u'r sure of it.
** i'm not a developer or expert. i may not be able to help in all querries. if anyone can, pls respond to qn's.

Hey I followed this guide step by step to the point...

But I find after all this, my device is still developer locked...

I did do the DEV_UNLOCK.cab
& the ROOT.cab

those two, I ran them both...

but I still have issues, I can not sideload ANYTHING...

I can no longer use the dev unlock & root cabs as it just pops up with an error... any help?

that thread describes (nicely) how to update to 7720 online using zune.
this thread describes how to update without zune offline.

two different things :)

My apologize for the confusion, I read again the other topix where I beleived it was also treated :eek:

Nice idea for people like me who are still on XP :eek::D

I have spent a week trying to get to 7720. A combination of this and Zune.. got the job done. Thank you!

One thing to add re: the 7661-7712 step. The update failed. The update system reported comms lost and reset - but AFTER having transferred the update files to the phone. It must have been randomly rebooting during the night because I this morning the phone showed a welcome screen with red highlights and 7712 was there. I guess once the files are on the phone and it's rebooting the PC connection doesn't matter.

I share this in case anyone else is as dumb as me and pulls the battery or resets when frustrated with seemingly random reboots and crashes during the updates. Patience is vital. A few times I've had black screens but the phone hasn't rebooted. (which when plugged in is odd with magldr) Left alone, 10 mins later it reboots and works. Suspect my own impatience made this much harder than it needed to be.

Never ceases to amaze me how good the devs on xda are. My wife hates them all and the " 'kin lump of a phone you're always messin with" - but I am in absolute awe of the talent on this site! Thanks devs. Now, off to mess with the phone some more :)

OKAY Still not jailbroken...

I have followed EVERY SINGLE POSSIBLE STEP POSSIBLE, when you said reset from about screen, I DID RESET FROM ABOUT SCREEN, when you said (it's safe) I RESET FROM THE ABOUT SCREEN...

I used the SAME package for lang in ALL updates...

After I installed the HD2fix, I AGAIN reset my phone...

But seriously, how do you sideload apps?

What program do you use?

    I'm currently running 7004 and want to try the "7004-7720 One Shot".

    Do you need to reactivate Live services?

    My 7004 has Live services activated but I can't find my activation code I had written down. Will I need to get a new one?

    Here i provide the step-by-step used to get 7720 after several problems.

    1. Get inside magldr, enable 24 MB and erase the MBR. Get to USB Flasher.
    2. Download and install properly YukiXda-XboxMod V2
    3. On the welcome page, do nothing. Leave it there.
    4. Download and extract WP7 tool update in a folder "WP7 update". For Windows XP, get the additional file provided.
    5. Download and extract 7720 fix to "WP7 update". Install x86/64 tool regarding your computer version.
    6. Download and extract 7004-7720 one shot to the root of "WP7 update".
    7. Launch the .bat files, click B or S, and wait for one hour, until the phone reboot. Don't touch anything until the "update is successful" message comes out.

    It's 7 easy step to get latest version of WP7. Hope it helps! =)

    P/S: And for the activation code, you can get a new one. If you want to use the same mail address, ask them to re-send you the ancient one. Whatever suits you better.

    nuts, maybe I stopped the update, can I remove all the other cabs from the sender folder except the 7720 ones and run the bat file again?

    Both of u, @ohdaesu and @thedante, are u sure u use a compatible SD card? Your syndrom are both incompatible SD card problem. And plz do not forget erasing the MBR. Try with other SD card n let me know what happens.
