[GUIDE] [XOOM2/XYBoard]: How to update Xyboard wifi (MZ615) to Jelly Beam (4.1.2)

[DHD]

Warning:
1. This guide comes with ABSOLUTELY NO WARRANTY. I'm not responsible for your data, your Xyboard, your girlfriend or something else . But report at this thread if you have problem. I will try to improve this guide.
2. Follow every step of these instructions carefully.
3. Everytime you reboot or power on your Xyboard, it will stuck at boot screen with warning "CustomerID error, Contact Dealer...", And you need press "+", "-" volume key and "power key" simultaneously to boot. Because you need clear "cid" of your Xyboard to flash this rom.
4. Sorry for my terrible English. I'm Vietnamese


Start:


1. Download Jelly Beam fastboot file for Droid Xyboard (MZ617): [URL="http://www.teamblackhat.net/t...T_127-127-release-keys-cid2-Verizon-US.tar.gz[/URL] Extract by 7z to hard drive.
2. Download this file: [URL="https://dl.dropboxusercontent.com/u/22090623/MZ615%20guide/MZ615.7z%5B/URL%5D"]https://dl.dropboxusercontent.com/u/22090623/MZ615%20guide/MZ615.7z[/URL] (included moto_fasboot, fake_cid, adb. I'm sorry for "license", "rights" because I'm collect it from many thread on many forums. Thereforce I'm can not remember the authors of those). Extract to same folder with fastboot file at step 1.
3. Download and install RDS lite, Motorola Device Manager (google for links, sorry).
4. Backup and Reset your Xyboard.
5. Install Terminal Emulator (free on Google Play)

6. Backup your cid (very be carefully, more information here: How to update you Razr (Gsm) To Official Jelly Bean - xda-developers)
6.a. Open Terminal Emulator
6.b. Run one by one:

su
cd /dev/block
dd if=/dev/block/mmcblk1p15 of=/sdcard/cid.img

6.c. Copy "cid.img" file from your Xyboard to safe location (you should keep at least 2 copy on diffirent location, backup on cloud or store it in somewhere safe). Double check this step.


7. Change your cid
7.a. Copy "fake_cid" file from folder you created in step 1 to your Xyboard.
7.b. Connect Xyboard to your PC, enable USB debbuging.
7.c. Open terminal on PC (Windows + R: cmd), "cd" to folder you created in step 1. Run one by one:

adb shell
cat /sdcard/fake_cid > /dev/block/mmcblk1p15
exit

8. Shutdown your Xyboard. Press and keep "-" volume key => press Power key => release 2 keys => your Xyboard will boot in fastboot mode.


9. Flash your Xyboard to Jelly Beam
9.a. Open terminal on PC (Windows + R: cmd), "cd" to folder you created in step 1.
9.b. Run one by one

moto-fastboot flash motoboot motoboot.img
moto-fastboot reboot-bootloader
moto-fastboot flash devtree device_tree.bin
moto-fastboot flash boot boot.img
moto-fastboot flash system system.img
moto-fastboot flash logo.bin logo.bin
moto-fastboot flash cdrom cdrom
moto-fastboot flash preinstall preinstall.img
moto-fastboot -w
moto-fastboot reboot

10. Your Xyboard will reboot and stuck at boot screen with warning "CustomerID error, Contact Dealer...". Press "+", "-" volume key and "power key" simultaneously to boot.
Now you are get Jelly Beam.

Update: Restore to ICS


11. Restore cid
11.a. Copy cid.img file (created in step 6) to folder c:\mz615.
11.a. Open terminal on PC (Windows + R: cmd), "cd" to folder c:\mz615.
11.b. Run one by one

moto-fastboot flash cid cid.img
moto-fastboot reboot

12. Restore to ICS: do it with RSD Lite (you can found a lot of guide on XDA)

OMG thank you very much!

I have the MZ607 though. It's the non-lte version. Should the procedure be the same? (i know the fastboot files would be different but does the cid number matter at all if I have a wi-fi only device?)


EDIT: I'm dumb sorry. MZ615 doesn't have lte/3G either. Though I would need the MZ609 fastboot files to do this. Where can I find them?

 

[pexlibanis]

Did anybody try this already?
Is it really working?

Can i use this fake CID to flash my MZ616 with MZ617 firmware? I think the only different of MZ616 and MZ617 is the gsm radio and additional sd card in MZ616 compared to verizon xyboard mz617.

Would affect me too

@DHD,

Can you confirm that if you have a working usb connection(mtp) ith pc after cid deletion? I knew someone would come up with this solution. Thank you for the guide.

Hi,
I tried with MZ607, but the files aren't accepted by fastboot. When I try to flash the files I got an error of verification failure.

 

[justmoto92]

Flashable for XOOM 2 MZ616?

Is it possible to flash it on my XOOM 2 MZ616? Desperately need an update... :crying:

I will try it tonight and report after that.

Sorry, I don't have it...

Becase you not clear CID before flash new rom.

Give it a try I did not have MZ616 but someone reports this rom works on MZ616 without nees clear CID.
Remember DO NOT flash radio.
If you want flash back to ICS room, just flash or "copy" back original CID afterthat flash ICS rom with RDS Lite.

I had try to flash the system img from MZ617 into the MZ616 but fail to do so. Do you think if i flash the boot.img, it will allow me to flash the system.img?

Yes, I clear my CID with fake_cid. But without success.

 

[Semseddin]

I wonder what was done to the " fake_cid" to make it a fake cid because CID partition is unique and it can't be flashed from other phones in any OMAP4 motorola.

"fake_cid" is "empty" cid. It's a trick to clear cid if you can not clear cid by adb shell.
Thereforce I think (and already tried on my MZ615) "face_cid" can use on any device if you determine exactly "CID" partition.

 

[mtvdeo]

I hope someone provides the fastboot file for my MZ607 (I would need the MZ609 ones).

 

[pexlibanis]

I just followed the guide on my MZ615 and it works flawlessly!

Also, in my case, when I get the initial error about the customer ID thing, I do not have to press -, +, and power button. If I just wait it continues booting normally after a while.

Thanks DHD!

MZ607 and MZ608 owners: you can have jelly bean too!

Find an ICS fastboot (there is no JB one yet), install it as if you were installing from the guide on page one. It might not work in normal mode, so go to BP tools and from then set it up and download the ota update. Then it will install it and work.



This is everything I did to my MZ607. It worked for me, and I'm no developer so please don't blame me for damage:

0. Mistakenly flashed honeycomb from verizon using the method on page one (CID + fastboot)
----HERE comes what matters, the actual GUIDE---
1. Found on a russian forum an ICS verizon fastboot so flash it like the guide on page one and do the CID thing before: http://translate.google.com/transla...da.ru/forum/index.php?showtopic=390298&st=560
TIP: moto-fastboot flash recovery recovery.img might be needed if you mistakenly flashed a honeycomb firmware
like me. But do it anyway if you have the ICS fastboot.
TIP 2: device_tree.bin comes with the fastboot you will download. The one from the OP doesn't work with this device. So use the one in the russian link fastboot.
3. Set up account on BP tools because normal mode didn't work for me.
4. From there downloaded OTA and it installed by itself.

I'm on JB now!
