[Q][SOLVED] Upgrading from Canadian Wifi 3.0.1 to US Wifi 3.1

Hi All!
I would like to convert my completely stock non-rooted Canadian Wifi Xoom (MZ604) into a US xoom so that I can install the 3.1 software on it, as well as root, sdcard capable kernel, and CWM recovery.
Unfortunately, after reading many many of the threads here, I am totally confused as to what order to follow. Here is what I'm thinking, but please please correct me if I am wrong:
[steps removed]
Is that it? I feel like I'm missing something or that I may brick my device since it is not a US-rom that I am using as a base.
Thanks for the help!
[update 28th May]: The steps that I followed to get 3.1 with CWM & Tiamat on my Canadian Xoom are below, in post #7.

1. boot the device into fastboot and unlock it. Erase all cache and wipe the userdata.
2. Flash the complete US 3.0.1 HWI69 ROM. (yes, do this)
2.1 Root the 3.0.1 Rom
3. Install CWM recovery from http://forum.xda-developers.com/show....php?t=1074979 using the fastboot method.
4. Install the 3.1 update from http://forum.xda-developers.com/show....php?t=1074609, skipping the 3G step since I only have Wifi.
5. Install Tiamat 1.4.2 from http://forum.xda-developers.com/showthread.php?t=978013. (update to one of the newest kernels)
6. Install International Language Pack from http://forum.xda-developers.com/show....php?t=1083612 to get back all languages from 3.0.1 ROM.

For your suggested step "2.1 Root the 3.0.1 Rom", would the thread at http://forum.xda-developers.com/showthread.php?t=1010568 be the suggested strategy?

that will work

So did you do all that you said ? Did it work ?
i'm about to do my candian wifi xoom !
Thanks

I was hesitant to do that since I am reading a lot of bricking stories lately, I have a canadian MZ604 stock too, will do the same if you succeed!

Alright folks, It's been a few days now since I've updated my Xoom, so here's the process that I used. Note that it is different from the steps I listed in the original post:
1. Unlock the device via fastboot. Instructions here. DO NOT RE-LOCK EVER!!
2. Flash the Official & complete US 3.0.1 HWI69 ROM. Links here. Every time I tried to download the "does not require login" version from mediafire I got a corrupted zip, so instead I downloaded from the Motorola developer site (with instructions) here.
3. Once the 3.0.1 Rom was up and running, and I had an internet connection, I got the OTA notification for the 3.1 update and installed it. It took about 10 minutes to notify me once I had connection, probably because it had to download it before notifying me. After the install and reboot process, I had a stock 3.1 install, but still didn't have sdcard access. So, I kept going.
4. Install CWM 3.0.2.8 recovery, using the fastboot method. Instructions here.
Once CWM was installed and I had the ability to backup the rom, I immediately made a backup before EACH of the following steps was performed. I know it is overkill to make that many backups, but I wanted to be sure I wasn't going to screw up my device at any given step and have to start over again.
5. Root the 3.1 rom from here. After rooting I had sdcard access within honeycomb at /sdcard/external.
6. Installed Tiamat 1.4.2 kernel. Instructions here.
7. Installed the Language Pack from here, but when I rebooted the system it went into a loop on the purple animated honeycomb logo. So, I rebooted into recovery again, and did a "wipe data / factory reset" - this allowed my machine to reboot normally, but I had to reconfigure all my settings and reinstall all my apps.
So as of right now I'm on 3.1 HMJ37, rooted, with CWM recovery, Tiamat kernel, and have international languages! It's great!!
Mike.

Thanks for the detailed info... I flashed the complete US 3.0.1 ROM on my canadian xoom and got the 3.1 OTA update as well. So now my canadian wifi xoom is on US 3.1 !
I will not root it for now since i don't really need the external SDcard for now.

When you say Flash US 3.0.1 ...do you have steps to do that? I'm just wondering how to do it...since I don't have a functional SD Card I guess its not the flash update.zip method...
Can't wait to be running the US rom and not care for motorola Canada anymore!!!

Just saw that the steps to flash the rom are on moto website! Sorry!

How to flash
I've spent hours on this and I guess I must be stupid, but I can NOT figure out how to flash a ROM! I've tried the ADB commands, I've download the ROM manager, etc, etc, etc...I cannot find any instructions on how to do this! It must be very simple because every time I look for instructions, they always just say "flash the ROM" like it's nothing. But HOW???
Very frustrating...there appears to be no single place that outlines all the steps in one place - it takes a dozen web pages to do the simplest things...
I also want to update my Canadian ROM to a US ROM. I'm unlocked, I'm running Tiamat 1.3.0 but I don't know what to do now...?
It seems as though having an external micro SD card supported is a prerequisite, but I cannot figure out how to get that to work either. The frustrating part of all this is that I do (Windows) computer support - I'm not new to technology in any way, but I have seldom been more frustrated than this trying to find one set of clear instructions...!
HELP!
Thanks.

after flashing using the instructions on post number 7 with the HRI39 bin images and fastboot my tablet doesnt boot. it just sits at the motorla logo for ages and ages and ages...
do I maybe have to wait like an hour or something?

Converted my MZ604 Singapore version to US & OTA update to 3.1
I managed to reflash International images to US and OTA update to 3.1 using a mod microUSB cable. I didn't need to root my xoom to do it rather a hardwired method.

2. Flash the Official & complete US 3.0.1 HWI69 ROM. Links here. Every time I tried to download the "does not require login" version from mediafire I got a corrupted zip, so instead I downloaded from the Motorola developer site (with instructions) here.

Can you please elaborate on how we do this? How do we flash a ROM? I only know how to do it in CWM Recovery, but not elsewhere.

Ok, hook your xoom up to your computer and open up a command line. Then CD to your tools directory of the android sdk and input these commands.
adb reboot fastboot
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot reboot
And your good to go..... continue from the next step just be carefully to input the commands exactly, and for the love of Pete DONT UNPLUG your xoom while flashing

And do NOT relock!!
Sent from my Xoom using XDA Premium App

I will be attempting this in the next day or so but had a few newbie questions (coming over from the apple world):
1) For step two, the img files all come from HWI69.zip?
2) For step four, do I want to do it with CWM or without? Is there more risk to one vs. the other?
3) For step six, to boot into recovery mode, is the following sequence correct?
Turn your XOOM off
Press Power to turn your XOOM back on
When the Motorola Dual Core boot screen appears tap Volume Down repeatedly until "Android Recovery" is displayed
Press Volume Up to enter Recovery
Thanks,

1) Correct - also, I know I keep saying this, but on the Moto site instructions for flashing they tell you to relock. Don't!!
2) I used the fastboot method (without). Make sure to download the img and not the zip.
3) I tend to wait on the Moto logo for about 3 secs then just press down once. Then up once you get the recovery option. Never fails.
Good luck.

Great. Thanks for the quick response. One additional question. This procedure seems a fair bit shorter in length than this one:
http://forum.xda-developers.com/showthread.php?t=1073884
Is there a reason? Is there a place where I can read some sort of a beginner's guide to rooting so I can understand the steps I am going to be following better?
Thanks again.

Question : why shouldn't we "RE-LOCK EVER" ?
I ask because I've relocked mine after flashing Europe stock on my US Xoom (I [stupidly] did what I saw on motorola dev instructions...).

[DEV HELP!] My Canadian Xoom Wifi fails to boot on HRI39.

Hey there guys
So I flashed my device as per these instructions:
1. Unlock the device via fastboot. Instructions here. DO NOT RE-LOCK EVER!!
2. Flash the Official & complete US 3.0.1 HWI69 ROM. Links here. Every time I tried to download the "does not require login" version from mediafire I got a corrupted zip, so instead I downloaded from the Motorola developer site (with instructions) here.

After flashing the images from the HRI39 zip from MotoDEV it did not work. My device wont boot. I have reflashed back to stock for the Canadian Xoom and that works just fine again, But I'd like to know why it wont boot with the other one since MANY people have done it without a problem.
I have executed these commands:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
Then manual reboot... simply sits at the motorola logo.
This is my 3rd attempt. Still nothing.
If anyone can provide some solid support it would be greatly appreciated.

Not sure, as i don't have that model, but i would recommend posting in Q&A.

I believe you're trying to use the vzw version on a wifi only xoom, that'll fail everytime. Find your version at the link.

Yes, you can... It is a good guide if you can follow it.. You must make sure that you have the latest bootloader and compatible TWRP.. Those are very important so you are not brick your device... Good luck and ask all the questions that you have before trying to install the TWRP and bootloader...:fingers-crossed:

ok so i'm having a bit of trouble following this guide...
1) I installed TWRP (with the help of this page) http://www.teamw.in/project/twrp2/105 I had to use the Download - Recovery Image / Fastboot Method because the app method wouldn't download the blob file
2) Now, when I power + volume down boot I can see my bootloader isn't the correct version. how can I update the bootloader? I have the files from the original link i posted (http://forum.xda-developers.com/showthread.php?t=2481892) so there is the correct bootloader i just don't know how to install it.
is there a more detailed guide with actual step by steps?

Congrats on getting TWRP installed! The rest is easy.
In TWRP select 'Install' and navigate to wherever you have the zip file with the bootloader/TWRP package, select it (if it has xxx signed.zip in the file name you need to check the "verify zip signature" option. sbdags usually signs his zips - don't know if he did with this one).
Swipe the button to flash the file.
When it finished, boot back to system. Do not flash a rom at this point! That would cancel the bootloader flash. Boot back into system first, then back into TWRP and then flash the rom.
BTW - flashing the modified Asus stock rom is perfectly fine, but I wonder why you don't flash CROMi-X 5.2.2?
That rom is from the same developer, based on this stock rom and miles improved since sbdags debloated the stock version.
sbdags stock rom is not really supported whereas he puts out a better version of CROMi-X about every 10 days! It's exhausting to keep up! LOL
You'll find it here: http://forum.xda-developers.com/showthread.php?t=2425383
You can still flash the BL/TWRP package you downloaded already. It's the same as the one for CROMi-X.

Thanks, Honestly whatever custom rom I have now can randomly reboot and i think is giving me touch screen issues so was just going to hit up a stock install and see if that fixes any problems.
gonna try out the rom you suggested and i can always go back if necessary.
one thing, when i installed theTWRP the blue bar filled up completely and i left it for about 10 minutes and it was still there. so i powered down and everything booted back up correctly (and i can get into the recovery mode).
does everything sound ok to proceed?

You have to kick it out when it is completed by using the fastboot command or just using your power button.. So you are good to go...
You have to try out all the rom and kernels that are available then choose the best one that fit your need...Good luck...

So now what can I upgrade my Stock ROM to?

Hello, I'm a noob at this so please be kind. I followed the below:
http://forum.xda-developers.com/tra...inners-guide-unlock-custom-rom-tf300-t3061648
I successfully:
Unlocked my TF300T's Bootloader
Installed custom recovery using fastboot
Rooted my tablet
Debloated the Tablet (Titanium Backup)
Backup up my current (OEM) SYSTEM ROM to microSD
So now I'm onto attempting a custom ROM. I'm a bit bored with 4.2.1 and would like to go to the same version of ROM my Note 7 has which is 6.0.1 Marshmallow or even try the new 7.0 Nougat.
I'm a little confused as to what ROM will or will not work. I see a few ROMS worth trying, but there install instructions reference a different Bootloader multiple flashes such as SuperSU or gapps.
Whats the best fool proof method to flash a new ROM with what I have and are there any simple one file ROM/ZIP/ Blob etc.. file that would do what I want?
Thank you.

Please take care very exactly on the installation instruction in post #1 given by Timduru. And don't forget that you need Kang TWRP [email protected] Download here: http://forum.xda-developers.com/transformer-tf300t/development/recovery-twrp-t3046479. That's mandatory!

Thanks. As simple as the process was, as a noob (first time attempting this) I was really concerned about screwing this up and bricking my tablet.
The one you linked to was one of the ones I was considering and hence my question regarding what works with what I have already done. The noob mind (mine anyways) finds a dozen questions at every turn. In this case I would ask the following:
Q-Do I have to use Kang TWRP?
Q-How is it different than the TWRP I used on my Tablet?
Q-Will I need to constantly change TWRP versions depending on what ROM I want to use?
Q-Is there a danger to switching TWRPs?
Q-Doesn't flashing SuperSU after I flash Gapps overright and erase SuperSU or is there some unique way to flash (push?) both at the same time?
Q-Many more I'm sure!
To the noob, almost all the instructions I read appear to be written for someone who as done this many times. The level of detail needed for the novice is just not there or lost between the jargon used, with many steps not fleshed out because the author assumes a certain level of expertise.
I will definitely read these threads as best I can, but in the interim, is there any ROM that are known to be able to be flashed via the TWRP I currently have? The author of the version I used certainly made it seem like it was that simple, load the ROM/ zip file onto the MicroSD card and when in Custom recovery simply use the INSTALL feature to navigate to the file and press a button to flash and ..."BAM!!" you are running a new ROM.

That version of KANG appears to be dead, as the thread has been closed and abondoned by the OP. So no new questions or help there....
Can I install that version over the top of my current version of TWRP the same way I did the first time? (change file to TWRP.blob etc.)

Please don't brick your tablet. First download Kang TWRP. It isn't dead. Try this https://www.androidfilehost.com/?fid=24052804347781183.

Can I install that version over the top of my current version of TWRP the same way I did the first time? (change file to TWRP.blob etc.)

Yes you can.
However Kang TWRP is a xxx.img file. You also can use your current TWRP and flash the image file. Attached you will find an image and a zip version.

Sorry, bad choice of words on my part. By dead I meant that the thread was closed and I'm concerned getting answers would be harder as the OP was no longer actively looking there for questions.

Ok, so if I read your comment correctly, I can copy the .img file to an SD card, boot into recovery and flash it from there OR I can fire up fastboot and the same steps I originally did to install custom recovery from my PC to accomplish the same thing... either way I should still have custom recovery, but with the KANG version. Right?
THANKS TO BOTH OF YOU FOR RESPONDING TO MY PREVIOUS POST. I appreciate the support.

Oh no....
Well crap. I put the .img file on my SD card and boot the tablet into recovery, I flashed the .img file to the rovery not boot partition. All appeared well....but when I go back to see if I have KANG recovery, it hangs anbd says Booting Failure Unrecoverable bootloader error (0x000000000)
EDIT: After I cleaned my pants, I used abd and fastboot to flash the original Blob file using my PC. This restored the custom recovery. I was freaking out for a few minutes.
I didn't change the file name of the kang .img file. Should I have done something different?
EDIT: Successful recovery to Kang2.8.7.2 !! :good::good: I used adb and my PC to send the .img file (renamed "twrpkang.img" for simplicity) and it worked great. I'm a pro..:silly:

Bad luck! Could you please describe what does it mean? : "I flashed the .img file to the rovery not boot partition."

Not sure what I did wrong. I tried to do it within the old recovery menu and it hosed it. It found the file and mounted it successfully, but it seemed weird to be within the partition I was overwriting and writing to it. Kind of like you cant install windows while your using Windows...
The new version is much smoother.... Thanks, not to learn about this gapps super SU and how to flash all of these and in what order along with the ROM..as well as this wipe vs format thing...so confusing...

Best ROM for ASUS TF300T for internet browsing and youtube

Hi everyone!
After three years of a very PAINFUL experience with my TF300T, I was about to throw it out of the window. But I actually thought that I could maybe try to install some custom ROM to make it work better.
The tablet is really almost unusable, because of the fact it is so slow. Youtube videos lags beyond imagination and often the audio desyncronizes with the video itself. Browsing experience is equally sluggish with either the stock browser and chrome.
I would like to ask you guys which ROM you think is the best for these things: Youtube watching and browsing. Of course I could use other apps, but this is the main purpose of the tablet for my actual needings.
I have been reading about Katkiss roms, but there are a few versions around and I really do not know anything about flashing roms and customizing android devices. This would actually be my very first time.
The only thing I did was reverting the tablet to Android 4.1 with the official Asus installation file. After a couple of days, noticing I wasn't experiencing any significant improvement, I let the tablet automatically update again to the latest 4.2 version through the update function.
Considering this, I would also kindly ask you to eventually link me the NOOB PROOF installation guides for the ROMs you will advice me to install. I am quite scared to just destroy the tablet
Thanks in advance to whoever will spend some time to bother answering me! And sorry for any grammar mistake I could have made writing this, english is not my native language.

Being on the last Asus firmware update is a good condition to think about installing a custom rom on your tablet. However first of all you have to do your homework as follows:
1. Unlock your boot loader with the Asus unlock tool after download from the Asus web site,
2. Install the custom recovery Kang TWRP [email protected] (http://forum.xda-developers.com/transformer-tf300t/development/recovery-twrp-t3046479). There is also the install instruction!
After done this both successfully you are ready to install one of the best custom rom ever "KatKiss Nougat 7.1 Release" http://forum.xda-developers.com/transformer-tf300t/development/rom-t3453702. Download the latest Rom, Gapps and SuperSu there in post #1. Please follow the install instruction given by the developer in post #1 exactly . After that you will enjoy the new life of your tablet.

Thank you for your answer!
I have already downloaded the latest Asus unlock tool (version 8) and I'm waiting for the tablet to charge to 100% before doing anything.
I have also take a good look at the KatKiss Nougat 7.1 version 12 you linked me. I understand this version is quite new, so I guess it could be less stable and optimized than the older Marshmallow version. I have also read a few people complaining about wi-fi disconnect issues (which I would definitely hate to have).
I do not care about a specific android version for my tablet, I just want it to run smoothly and without any issues and headaches considering this, would you advice me to install the Marshmallow version or the latest Nougat one?

Finally it's up to you which one you are going to use. I had been on MM 6.0.1 since version#10. Now I have been on N 7.1.0 since version #6. I have never had any problems with WiFi, Audio, Calendar or something like that. All versions run very well, smoothly and stable.
However in both cases you need Kang TWRP in order to be able to format /data to F2FS. This gets the better performance.

Thanks again for the time you spend answering a total noob
At this point I would like to ask which version do you actually like the most, before deciding myself.
Plus, I'm getting ready to install everything, but I'd need some confirmations first.
I have just successfully unlocked the boot loader.
Now, to install the Kang TWRP, do I need to download something called "fastboot"? I read this on another guide, because the actual link to the Kang TWRP doesn't exactly tell me how to properly install it. Or at least, I feel like there are advanced instructions I can't fully understand.
After installing the Kang recovery, the guide says I should do these things:
1) do a full wipe , if you have issues make sure that you format /data (format is different than wipe). I guess I can do the WIPE from the recovery menu. Should I format /data after said wipe? If the answer is YES, how should I do that?
2) Change /data filesystem to f2fs. The guide once again doesn't tell me how should I change this thing.
3) Flash the rom. I guess I have to install the ROM from the recovery menu.
4) Flash the SuperSU zip. I assume I can do this from the recovery menu aswell
5)Flash gapps. Always from the recovery menu?
6) Wipe cache/dalvik. No additional info is provided, how should I do that?
7) Reboot
Thanks in advance for the clarifications eventually provided I feel like I'm just adventuring myself in a new, huge world.

First of all you need „Minimal ADB and Fastboot“. The USB driver must be installed on your PC.
Download “Minimal ADB and Fastboot”. Make a folder C:/Fastboot and extract it there and install it on your PC. Download Kang TWRP and put it into the folder C:/Fastboot and rename it to twrp.img
Start your device in fastboot mode and connect it with your PC. Open “Minimal ADB and Fastboot” and put in "fastboot devices". The device should appear as "xxx device".
Put in "fastboot -i 0x0B05 flash recovery twrp.img" without " ".
After that you should have Kang TWRP. Format F2FS with TWRP: Wipe => Advanced wipe, check the box for data then click on Repair or change file system, then click F2FS. But /Data only not /System or /Cache!!!
Finally do all 7 steps. Flash rom, gapps and SuperSU in one run. Wipe dalvik/cache. After that reboot.

Thanks, really! You're very kind I'm already downloading everything needed.
Which version do you actually prefer? Are there any difference on the battery life between them?
And also, if I install for example Nougat, can I eventually revert to Marshmallow if I want to?

I'm trying to install the recovery, but it seems that something is going wrong.
This is what appears on the screen:
C:\Fastboot>fastboot -i 0x0B05 flash recovery twrp.img
target didn't report max-download-size
sending 'recovery' (7126 KB)...
OKAY [ 2.805s]
writing 'recovery'...
OKAY [ 8.019s]
finished. total time: 10.825s
After that, it seems that nothing has actually changed. I tried rebooting with C:\Fastboot>fastboot -i 0x0B05 reboot but it just reboots normally. If I try going in recovery mode, I still have the old stock recovery mode.
What am I doing wrong?
(Ofc, in the meanwhile I'm pressing the thanks button )

What bootloader do you have? MUST BE ON A BOOTLOADER ENDING IN 27.1 or 27.5.
Please check starting fastboot by power on and volume down. In the left corner should appear "WW_epad-10.6.1.27.5".

EDIT: solved, I had to press volume UP to enter RCK!

It seems that everything went ok, but I got ERROR 70: insufficient space when installing gapps. How can I solve that?
Eventually figured it out myself, I had to take either the pico or nano version! Gonna do it all again

Thanks mate! Really!
I am experiencing an issue though. I am getting wi-fi disconnecting every couple of minutes, or even less. I've also written in the marshmallow thread, hoping to get some answer.
Is there a way to fix this? Will eventually the new build Nougat solve this?

I'm sorry, but I have no idea. Timduru suggests "Try increasing the group rekeying interval on your router".
If I were in your boots, I would try a clean installation of Nougatella to see whether it's solved or not.

Thanks as always for the suggestions.
I had some time today and flashed Nougatella. Unfortunately, the wi-fi issue it's still there. No sign of improvement at all.
I'm starting to get a bit mad on this. Is there any previous version without any known wifi issues? I am even open to try other ROMs. I just want my tablet to be good for internet browsing and youtube watching...

I'm so sorry for that because I was very hopeful the issue will be solved.
First of all, please check your tablet within another stable network like a free WiFi somewhere. If there is still the same trouble please make a logcat and send it to Timduru. Maybe it helps to figure out the cause. Using the terminal emulator: su ->logcat. Save the file as "logcat.txt".

Thanks for the tip. Unfortunately I don't actually have the time to test other wi-fi networks, and above all, it would still pass A LOT of time between my log sending to timduru and EVENTUALLY him taking care of the issue (provided he would).
I'd need a quick solution to make the tablet work again, considering I haven't been using it for days because of this wifi problem.
Would the Lollipop katkiss version work with the same recovery? Are there still people lamenting the same issue even on lollipop?
Can you please tell me if there are any other decent ROMs I can try with the same TWRP recovery?
