Can anyone share the 4G LTE system/boot dump?

[kcrudup]

Yeah, it does. The radios are in the bootloader, aka mmcblk1p1, aka the ebb partition.

Theoretically, we should be able to get a dump of the post-upgrade bootloader, dd it over our borked bootloaders and have it working. Problem is, getting that dump and figuring out how to do the flash. We definitely don't want to do it in a powered up system...that leaves recovery or fastboot.

Hope this helps someone, then: http://dl.dropbox.com/u/12011163/hlk75D-ebb.zip

The problem I see is that the radio code has to be FLASHED to the radios- and I know there's code in the upgrade.zip that does that, plus those radio images are much bigger than the 3MB bootloader.

If you disassemble one of the ...-to-hlk75c images, it'll have the files you need and the procedure (and I think the radio images are true files, and not .p files).

Ok that's interesting. The md5sum matches mine so I'll have to assume that something else goes on here. Out of curiosity if you do a BP tools boot (power up normally and press both volume up and down at M) does it say "LTE radio is off"? Maybe that's normal at this point in the boot process and a red herring to this investigation.

Yeah. Been trying to get my bootloader to update. Bigrushdog has a file out there that updates the bootloader using Motorola's method - I've tried and no luck.

I managed to get that dump into a .sbf file - CG44 for reference - still reads as version 1045, even though you have 1050. The posted MZ602 SBF has the proper radio images. I'm thinking the new bootloader is in misc, aka mmcblk1p3. Dunno what code group that is, or what's in it. And I don't recommend using cat or dd to overwrite it. #xoom on freenode if you want to chat.

You can get the hlk75c which is rooted then take the hlk75d update and reroot using the universal root method. That will put you back.

My sad story;

1> Updated to the solarnz build after i got my xoom back with 4G and lost wifi
2> Tried going to build 1.0 to fix wifi - NO HELP
3> Unrooted and flashed back to 3.0 build and did all OTA updates - Fixed wifi, broke 3/4G
4> did this;
http://forum.xda-developers.com/showpost.php?p=18224303&postcount=6
-NO HELP
5> Installed solarnz build 1.1 again to try and fix 3/4G - NO WIFI OR 3/4G!!!

Going to verizon tomorrow (or should i say today? It/s 415am here) to try and dupe some 18 year old into giving me a new xoom bevause "Mine never worked since i got it back" - Lets hope this works!!!

Updates to follow

Solarnz' build is not an upgrade. HLK42B is his, it ships back with HLK75D.

When you downgraded it overwrote your bootloader to version 1045, aka 1.45.

The bootloader you need for LTE to work is 1050, aka 1.50.

Nothing to do but wait. Going to VZ won't help.

How do I rip the bootloader out? I am still on 1.5.

Can't. We've tried. Normally, it would be dd if=/dev/block/mmcblk1p1 of=/sdcard/ebb.img

Then either a) put it into a special .zip or b) unpack a bootloader flashing .sbf, rename the dump to CG44.smg and re-pack it into the SBF.

Method B is riskier. But yeah, we've tried.

I know.....

Didnt have time today, but going to see if VZ will swap it for me. It's worth a shot! :/

Someone needs to take hlk42b down! People keep flashing that crap and it ain't right! I swear someone thinks it's funny to point people to that build knowing it downgrades people!

I know this does not fix the bootloader issue but here is a fresh nandroid of my Xoom. Just got it back from Motorola after doing what you all did and crapped out my Xoom. Had to send it back for "repair". This is a clockmod backup. This will put you back to factory after 4G upgrade if you have not destroyed your bootloader. Good luck!

Hi everyone,

Being as I'm kinda new to the Xoom and the architecture of the radio/bootloader, I read this thread verbatim but still have a question...

Are the radio and bootloader separate partitions or are they combined. Someone mentioned the radio files are in the bootloader, so I wasn't sure what that meant exactly. For instance, on the Nexus S, you have a bootloader image and a radio image that can be flashed using fastboot (fastboot flash radio file.img, fastboot flash bootloader file.img). Is this not possible with the Xoom?

When I open up the HLK75F-from-HLK75D OTA update for MZ602, I see a 24 MB file called lte_bp_gota.img. Judging by the filename, I'm guessing that's purely the radio image, but is the bootloader in that as well somehow? When I look at the update script in the ZIP file, I see the following line:

assert(motorola.motoflash(package_extract_file("lte_bp_gota.img")));

Seems odd that Motorola would have their own radio flash utility (in lieu of something like write_raw_image which is more standard) unless they were combining the radio with something else (perhaps the bootloader?)

Can someone satisfy my ever-curious brain and shed some light on how this works?

im glad this thread is not dead yet!! but can someone please help me out I've been stuck in loop holes in trying every method in getting my 4g to work. I have the bootloader to 1.5 and confirmed it through RSD ive flashed all the stock images for 3.2.2 wifi seems to work but in the status network is unknown, mobile network is unknown, service state is out of service, mdn and meid is unknown baseband is still showing unknown any ideas would be greatly appreciated!!!! Wow my first post

Hey was wondering if you still have that backup would like to try if this fixes my 4g problem downgrading my xoom from 3.0
I've flashed 1.5 bootloader so hopefully by me running your backup file it might fix my problem because im running out of patience and time trying to figure this out!!!

 

[fudsak]

I was messing around with my Xoom trying to unlock/root it and accidently used an incorrect boot.img. This thread and Ace's backup saved what I thought was a bricked device. Thanks a bunch.
