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

[bathanr]

I tried to use the rooted 3.2.2 rom that was listed under development, but I could never get my wifi to connect. Now I am unable to get my 4G to work. I used to have the option to choose preferred network mode LTE/CDMA, but now that no longer shows. I am on 3.2.2 using build HLK42B.

I was wondering if someone who received their xoom back from the upgrade has the latest image I can try.

Tell me how to dump it. Never done it before. I am n stock 3.2.2 fresh back from the upgrade.

You need to flash the modded recovery, then in adb shell, run

mount /data
mkdir /data/media/Stock
dd if=/dev/block/platform/sdhci-tegra.3/by-name/system of=/data/media/Stock/system.img
dd if=/dev/block/platform/sdhci-tegra.3/by-name/boot of=/data/media/Stock/boot.img
sync

Then reboot and pull the files, should be in a "Stock" folder on the internal storage.

*Thanks to solarnz for these instructions

Ok, I have pulled HLK75C images which should be flashable through fastboot thanks to short/y's Rogue CWM nandroid backup. Usual disclaimers apply here, don't try this unless you know what your doing, not my fault if something messes up. That being said, download images here: http://dl.dropbox.com/u/22648028/HLK75Csystemboot.7z zip password is "AceXMachine" without the quotes. After unpacking files go to the command prompt

adb reboot bootloader

fastboot flash boot boot.img

fastboot flash system system.img

fastboot erase cache

fastboot reboot

It goes without saying that you need your xoom unlocked for this, need adb setup/working and may need to wipe data. I would do a nandroid backup of your current config before doing this. I was able to restore the "data" backup from a previous backup after restoring the "system" and "boot" from short/y's backup. Only problem I had was my market shortcut on the home screen had to be replaced since my "data" backup had the link to the older market. I rooted this before pulling these images so you should already have root when you flash this. I tested and have working WiFi and 4G with this setup. Feel free to ask questions or PM me if needed. Thanks again to short/y for his nandroid backup...even if he did make me load the Rogue recovery just so I could use it ;P

4G LTE

I got my Xoom back some time ago. I've been waiting to root it until it came back. (Really didn't want to go through it, and have to undo it just to figure out how to do it again)

I'm trying to find the official file from Moto for the HLK42B build that came back on my 4G Xoom. I'm on the Moto Dev site, but they only have up through the 3G upgrade listed. Anybody know where I can get the official file in case anything goes wrong? I want to make sure I have it, before I start.

Thanks

Thanks Ace, it worked for me. It wasn't rooted because I imediately got and updated to HLK57D

Thanks for the img files. They will save many headaches for a lot of people.

It is a damn shame that Motorola will not post the updated img files though...

I've tried both Ace and Shorty's backups. They seem to work restore fine but I still can't get any 3G/4G data. I've tried both HLK75C and D. I've done many factory resets and cache wipes. I had VZW send me a new SIM card which they manually activated while I was on the phone with them and according to their end they can see my Xoom contacting the tower but there is no activity beyond that. I really never believed that was the problem since I was able to swap SIMs with my Bionic and the Bionic worked great with the Xoom's SIM (but not the other way around of course).

I'm still suspicious about the radio Baseband version. I am missing the second "ltedc_u_05.19.00" that I've seen in HLK75C screen shots and I don't have the option to select a network mode under Mobile network settings that I know needs to be checked. This makes me think my Xoom's hardware is ok since it is able to talk with the tower over the 4G modem for activation, however the OS software is not able to select the 4G radio for actual system use. Are the radio files built into the system or boot images? Where do the baseband versions listed in About tablet come from and how might these be backed up/restored? I've never really bothered flashing radios before so this part of the process is new to me. I'm really hoping this can be solved without having to return the device to Moto.

This is my same exact problem. Can't seem to figure out the baseband problem.


I wonder if anyone has contacted Motorola regarding a way to flash the baseband to the LTE 4G version?

Hey guys. Been going through the same ****. The MEID/ESN changes with LTE upgrade. Adds a 01 or 02 to the end of the ESN. If you downgraded and took updates, it modified your baseband, taking out the LTE part of it. If you go back to HRI66 and do the CDMA activation thingy, you should be able to re-activate on 3G. Yeah, it sucks, but what else can we do? We need that OTA to re-flash the LTE baseband.

 

[hammer4203]

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.

Oh, duh, it's so simple. I'll definitely be trying this when I get home from work today.

If it works - you will be my savior.



Scratch that - it didn't even reactivate my 3G.

I don't think that will work unless you open it up and physically remove the LTE modem. my understanding is once the LTE modem was installed the internal 3g modem is deactivated. Even if this did work it would deactivate your SIM card so you wouldn't be able to use LTE in the future without getting a new one. I had the idea to switch my currently useless Xoom data plan over to my old OG Droid and then wifi tether. I asked VZW about switching and found I *could* do this but going from a 4g device back to 3g would deactivate the SIM card and I won't be able to switch without getting a new one. Too much trouble in my opinion.

I spent about 2 hours in a Verizon store yesterday after 2 hours on the phone the previous night and eventually ended up with an RMA with Motorola. I'll be returning it to them and hopefully it will come back correct in about a week. Such a hassle when I could probably flash this myself if I had the right files but at this point I don't know what else to try.

This does not work I've tried it a bunch of times in different fashions. I even flashed 3.2.2 then flashed the official recovery took the next update and nothing. Actually its been said that HRI66 over rights stuff that we need. Take that with a grain of salt.

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.

It restores your device but it will not bring back 3G/4G. If it does please tell me how because I've flashed it a few times and it did not bring back 3G.

Actually in reading your post a few times you say it yourself that its a borked bootloader. Flashing HRI66 will not fix this. If it did we would be finished and we could close this thread.
