Troubleshooting for Newbies (having a "wtf!?" moment?)

Most of this information has been repeated so many times. But I wanted to make a short list of all the silly mistakes and simple oversights I’ve made over time.
(I make mistakes constantly - there are probably some mistakes in this very post - and I usually search around and try to find my way out of them. I will edit this post whenever I run into a problem. If anyone has any input, I will gladly add it to this post.)
YOU CAN NOT COME BACK FROM UNLOCKING YOUR BOOTLOADER:
If you ever think you’ll need to or want to “relock” your bootloader, you can’t.
Alternative root method:
VISIONary
(when you launch the application, you can leave everything unchecked)
Alternative recovery option:
ROM Manager (in the market)
ALWAYS DO A NANDROID/CLOCKWORKMOD BACKUP!
It will restore everything the way you had it if you F something up.
Want to go back to original shipping, but followed this guide, downloaded the linked file and can’t find the image files?
They’re not in that file. I don’t know why. Go here and download FRG33, decompress it and use the contents to follow the tutorial
Are you getting a “verification failed” error when you try to apply an update.zip in recovery?
Mount your SD card to your computer, download whatever file you were trying to apply directly to it (don’t download it and then drag it), and rename it to “update.zip”.
If you’re using Windows, make sure “hide extensions for known file types” is unchecked in your folder options within the Control Panel. You’ll keep having problems if it’s named “update.zip.zip” and you didn’t realize it
If you're still having problems, try this download of the stock FRG83 update.
<Added 11/18> I had another facepalm moment. If you downgraded back to FRG33 and you get an "assert failed" error, flash the recovery.img from that FRG33 package you extracted. (found this solution here)
Did you flash a ROM or go back to stock, start up your phone and noticed that you’re stuck on Edge?
Go to Menu>Settings>Wireless and Networks>Mobile Networks>Network Operators>(choose your carrier), wait.
Trying to copy something from your SD Card to /system/app (for instance)?
If you use the “cat” command, DON’T FORGET THE “>” SYMBOL. Nothing awful happens as far as I know, but it’s unnerving to watch the terminal puke all over itself.
Code:
cat /sdcard/thing.apk > /system/app/thing.apk
If you’re new to Linux and/or Android and are removing apps:
BE CAREFUL with the “rm” command. Once it’s gone, it’s gone.
You can always rename (technically, "move") the files instead:
Code:
mv /system/app/thing.apk /system/app/thing.apk.bak
Switch the commands to get it back
Code:
mv /system/app/thing.apk.bak /system/app/thing.apk
And don't forget to mount /system as read and write. To do that:
Windows: (must have drivers installed, Nexus One drivers are in the SDK)
Code:
adb shell
su
Linux: (no drivers necessary)
Code:
./adb shell
su
Code:
mount -o remount,rw -t yaffs2 /dev/mtdblock3/system /system
Don't forget to mount /system as read-only when you're finished. To do that, use the same code but replace "rw" with "ro" (without quotations of course)
Having trouble connecting with adb?
In Linux, you need to be in the SDK directoy (mine is in ~/AndroidSDK/tools). In Windows, you need to have ;C:\AndroidSDK\tools in the system path, within Environmental Variables (right-click on Computer>Properties>Advanced>Environmental Variables)
Unplug the device
In Linux, cd to ~/AndroidSDK/tools (or whatever you called it) enter:
Code:
sudo ./adb kill-server
sudo ./adb start-server
Plug in the device
Code:
sudo ./adb devices
In Windows:
Code:
adb kill-server
adb start-server
Plug in the device
Code:
adb devices
Device not found?
Did you enable USB Debugging in Menu>Settings>Applications>Development?
Trying to install an .apk but it just won’t work?
Try the “adb install” method, or push the apk to /system/app. If the app force closes or doesn’t work, just remove it
Code:
rm /system/app/thing.apk
Using Ubuntu (or another Linux distro), trying to mount your SD through Amon-Ra's recovery, but it won't mount?
Disable USB-MS toggle, unplug the phone, reboot your computer, try again.

Can I kiss you?
Seriously though I really appreciate it when the guys on here take time out of their day to post helpful guides like this since it prolly took 30 min at least. Thank you very much for doing this it might have been just what I'm looking for

I'm glad you appreciate it. I'm not technically one of the guys on here. I've been on XDA in different device forums for a little while but have always been absorbing the information and never giving anything back. This is my first try. I can only dream of being a developer when I grow up, and solving more serious problems.

Just wondering ahorriblemess, I looked over the guide and it says:
"This will do the followings to your Nexus One:
1. Reset your system files to the original system files.
2. Reset your kernel/boot image to the original shipping boot image.
3. Reset your recovery to original recovery (if you wish)."
Since I'm a real idiot... does this guide get your baseband / radio back to original (january) shipping image as well?
I didn't see it in those 3 things and have the 5.12.00.08 version so I wanted to make sure following that guide would reset the radio baseband back to the original (january) version as well before I did it.
Now all I need to do is figure out how fastboot works and I'm gold!

I don't know. I'm in no way an expert at any of this. My intent with this thread was to compile all of the sort of simple things that I've overlooked in the past. Usually I've found solutions to those problems scattered all over the place, so I just thought it would be helpful to put them all in one place in case anyone ever has the same problems I've had.
I have a pretty good feeling about the answer, but I don't want to share it in case you decide to act on it and it's wrong.

Thanks a ton!

[STICKY][ROM] nvflash FULL restore, using bekit's original image (Instructions)

MANY THANKS TO REV FOR RE-WRITING THIS FOR ME!
(Post was updated on 3/23/2011)
=======================================
This post is to provide a template for using NVFlash to restore/recover your G-Tablet after suffering some kind of malfunction. Specifically, this document tries to provide ALL the information you need to use the NVFlash tool to recover the bekit 1105 software version, which has been found to be safe as a starting point for rebuilding your tablet after having a problem. This post does not include other methods of setting up NVFlash (such as installing the SDK, etc.) because this method is proven and can be easily supported.
I use Ubuntu Linux and know that the Linux instructions below are correct. Others have written Windows instructions and those too have been checked carefully and have been used before successfully.
A WARNING IN ADVANCE: NVFlash makes changes to the partition structure of your device. You should tread carefully and understand the risks. (MOD EDIT Note: It also has been noted a bunch of times that even NVFlashing your G-Tablet will not completely overwrite everything on it.)
The NVFlash setup process begins with a visit to:
http://db.tt/Wm25t7U
(Note: Sometime this DropBox is cranky. If you have trouble with it, check back later.)
Linux users: You want to get "nvflash_linux_2010110500.tar.gz" and "nvflash_gtablet_2010110500.zip "
Windows users: You want to get "nvflash_windows_20100500.zip" and ""nvflash_gtablet_2010110500.zip"
Note: The above "nvflash_gtablet_2010110500" is commonly referred to as bekit version 1105 in many posts relating to nvflashing (especially my posts).
-------------------------------------------
Installation
First, create a folder named "NVFlash" on your PC to put the needed files into and to work from. (Note: You can call it something else if you want to; we're just using "NVFlash" to keep all of us on the same page.)
Next, extract the files you downloaded from the DropBox above into the "NVFlash" directory. The files with linux and windows in the middle of then are the files for setting up NVFlash. (The are taken from the SDK and do not install the whole SDK -- just a simple, operable NVFlash for us to use here.) The files with gTablet in the middle contains the .img files with the software to go on your G-Tablet.
Third, for Windows users, you'll need to have an APX-specific USB driver for the next steps. (The Windows package bekit supplied has an .inf file in it, but the actual drivers are not there). For Linux users, you don't need an extra driver.
One source for the Windows drivers is at
http://www.myadventvega.co.uk/
Find the "Downloads" tab in the middle of the page and click on "USB System Driver" to get the files. Extract them and go down two levels to the "USB" folder -- and move that into your "NVFlash" directory. The USB folder has the .inf file for installation in it along with two other directories with drivers for the various operating systems. (Note: These drivers, which are the same as the drivers in the SDK, are proven to work with Win 7 64-bit and have the setup include to load into other versions of Windows.) Follow this narrative for actual installation of the drivers.
CHECKPOINT: At this point, you should have the nvflash files, .img files, and USB directory (and files) in you "NVFlash" directory and are ready to begin the recovery process.
Now, you will need to boot into G-Tablet APX mode: hold down the power and volume - button simultaneousl until your G-Tab comes up and the goes back to a black screen. The black screen means it is in APX mode and it is waiting to display the flashing process. In Linux, type "lsusb" in a terminal and you should see this "0955:7820 NVidia Corp.". 7820 means the device is in APX mode.
Connect your G-Tablet to your PC using your miniUSB to USB cable that came with your tablet.
Linux users: At this point, open up a command window to the folder you created, and run this script:
./nvflash_gtablet.sh
This will wipe the device back to bekit's original TnT stock image, except for user data which is retained. Should take about a minute to run and the device will reboot itself automatically. If the script does not work, make sure that the shell script and nvflash binary are set as executables.
Windows users: When you connect to the PC, the PC immediately tries to load a driver -- but since it doesn't know where the USB driver files are it will fail. Click through Start/Control Panel/Device Manager and find "APX" listed in the devices with a yellow "!" (exclamation point) on the icon. Select the APX item and find the "Update Driver" button and click it. When it asks where to search, choose the local computer manual selection choice and tell it to Browse.
Point the Browse (and the USB install) at the "USB" directory under the "NVFlash" folder. When pointed at the "USB" directory, the driver installed and I was ready to nvflash. If you go back to Device Manager after the Windows install has completed, it will show the nVidia USB drivers near the top of the USB device list.
Again, for Windows: Run this script which is in the "NVFlash" folder:
nvflash_gtablet.bat
This will wipe the device back to bekit's original TnT stock image except for user data, which is retained. Should take about a minute to run and the device will reboot itself automatically all the way to the main screen.
POST NVFlash:
When your G-Tablet has booted back to the main screen, you will have to check and make sure everything is set up. Particularly, get the wifi on and connected to the Internet. Almost immediately, you should get a notice about an OTA (over the air) update. This is the OTA Update to software version 3588. If it does, go ahead and have it do the update. From there, you can begin using your "stock 3588" G-Tablet.
If you don't get an automatic OTA notification, you can go the to manual "Update" icon on your tablet and have it check for updates -- and hopefully it will find OTA 3588.
Or, if neither of the above happen, you can download 3588 at the following link and install it manually:
http://tapntap.http.internapcdn.net/tapntap/viewsonic/update-smb_a1002-3588-user.zip
Note: Following is a STICKY from General Forum on the stock recovery process:
http://forum.xda-developers.com/showthread.php?t=892090
NOTICE: There are many threads out there with tell how to do this process. Others tell individuals' problem solving experiences. A few of them may not be right! The above process is not the only way to do this -- but it is fairly straightforward and it is proven. It is recommended for anyone who does not have experience with nvflashing.

An additional suggestion if you also want to tack on bekit's clockworkmod recovery versus standard recovery: http://forum.xda-developers.com/show...3&postcount=17
Hope this helps!
03/2011 update -- I've been told that this tool has been useful to erase ALL partitions, including user data. I believe you need to re-flash with the bekit 1105 above, AFTER you use this: http://forum.xda-developers.com/showthread.php?t=974422
04/22/2011 update -- I've built out both 1.1-3588-based and 1.2-4349-based versions that have effectively replaced bekit's 1105 image ("nvflash_gtablet_2010110500.zip"), at least on my own device - I'm also addding a clockworkmod recovery option. It is being hosted in the same location as my 1.2-based mods - I will be making updates there, from this point on (as I might update them from time to time).
(you'd still need bekit's Windows or Linux tools, keep in mind) I've been able to bring back my device back from a soft-brick several times, so I feel they are usable.
05/09/2011 update -- A reminder that these images are not being updated, here. I have a newer nvflash post over in the same site where I have my 1.2-based mods. The 1105 bekit image mentioned here is still relevant for 1.1-based ROM users, or you can use my 3588 ot 4349 solution at the other site.
05/10/2011 update -- I have PM'd the moderator to either unsticky this post and / or assign it to someone else, as I do not plan on updating it, here. I believe that there is a 3588 image in the TegraTab IRC that someone created, for example.

Looks good Roebeet. I wrote a little how to a while back on tegratab. I know you are aware but for the benefit of others I wanted to add the following.
One little thing is sometimes when you are done you will get a boot loop. I think it only may happen once as I never saw it again. The fix is to go into Clockwork and partition the internal sd card again. The old settings said 512 for memory, and 256 swap. Bekit updated Clockwork and now you can format all the way to 4gb if you like, and swap should be 0 as it is not used.
Edit: New wisdom says not to partition the internal sdcard to anything but 2048. Folks have had issues with memory errors in the market with anything bigger. 0 for a swap is also the recommendation as Android apparently does not make use of the swap.

I need help. I finally got Windows 7 to recognize the device in APX mode but how do I flash from this point. It only shows up in my Device list with all the subfolders in it.

What is this for? Restoring to factory Rom?
Thanks,
Scott

Yes, you can use it for exactly that. I believe bekit added Launcher Pro and superuser, but other than that it's a way to completely wipe the device. Moreso than a standard recovery would do.

The pre-req link doesnt work. Can you update the link?
Thanks

Roebeet sorry but I just noticed for noobs that the linux command needs to be
. nvflash_gtablet.sh
Also if you unzip those files into a premade directory such as "gtablet" when you unzip them each have their own directories and if you ls you can see that the bash script isn't executable from there. So you need to copy either the gtablet files into the platform folders or copy all the files inside both into your "gtablet" folder. Then you can run the ". nvflash_gtablet.sh" command and voila. Sorry I am on Ubuntu and don't know if it is different, but that is the way I run them.

No worries - all replies are welcome! the more info we have, the better.

This should be stickied. Nvflash has saved my gtab many times and I think its the reason why my gtab doesn't really encounter too many Force closes. Its the perfect method to ensure your gtab is clean.

I tried this tonight to try to get my gTablet back to stock so that I could show people how to install CWM on a video but I could get neither of my Windows 7 64-bit computers to recognize the APX .inf that was included in the pack.
I have a linux machine around here somewhere I may have to use...

My limited experience with 64-bit Win7 -- the drivers have to be signed, or else they won't work. There's a way to disable that on boot, but you can't permanently disable it. I'm wondering if the APX USB driver is signed?

Open a command prompt as an admin and type
bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING ON
This is the only way.. dont worry if the test watermark shows up.. it wont affect anything.
Also... They have a x64 driver - read this

Hi there,
I exchanged for a new Gtab yesterday from sears (as it had some power issues).
Today, I tried TnT 2.2 on my rooted tab (Z4 for rooting). Also have ClockworkMod .8.
I partitioned my internal SDCard. But after vanilla restore, I could find my tab space reduced to 4 gigs. What should I do to restore to full 16 gigs(14+ gigs actually).
============================================================================================================================
2. I followed your instrction and partitioned again in clockworkMod and did 4 gigs and 0 in the second one. Now it shows 11 gigs for data and 4 gigs for system.
Now I inserted an external micro SD card (16 gigs) but my storage is not seeing it. What should i do? Ignore my first part please.

Your gonna have problems later if you don't repartition to 2048 and 0

You only have 16gb to start. Partitioning you internal to 4gb uses part of that. I would go back and only use 2gb, and 0 for swap. There are things, like the new market that break with anything but 2gb.
If you mean the settings menu is not showing your external sd card that's normal. Look in a file explorer program in the / directory. Look for SDcard2. That is your external. Same deal, look for usbdisk if you plug in a usb drive.

Roebeet
also this could be helpful to Ubuntu/linux users.
in the same directory where your flash script is there is a file that is called "gtablet.cfg" if you download the clockwork.img recovery and put it in this directory you can open up the "gtablet.cfg" with a text editor
scroll down to where you see "filename=part9.img" and replace "part9" with "clockwork" and it should now read "filename=clockwork.img" this will flash clockwork and save you a step. To change it back so you flash complete stock just edit the file again and reverse it.

You don't even have to do that - you can just rename part9.img to something else, and clockworkmod.img to "part9.img". That's actually what I do.

Yeah I thought about that, but figured some people might get confused and forget which one was which. Either way works as well just as long as you keep both files. You should edit your original post and add that in as an option to do at the end. It will keep some from having to look through and creating a new post cause they can't find it, and keep our forums clean.

This should definitely be stickied. Mods please?
P.S. I cannot believe how awesome this forum is(Viewsonic G Tablet). I have gone to other forums and the other devs and users are not as friendly and awesome as the ones we have here. Almost brings a tear to my eye. Great job Roebeet, this should help us noobs out a lot. LOL!

[GUIDE]Install Clockwork Mod (CWM) via NVflash

Hi all,
I've been playing around with Rom Manager and it seems to dork up the CWM everytime on the gTablet and somehow keeps me from reinstalling CWM via internal SD or microSD. I've just reinstalled CWM via NVflash w/o messing up the original ROM (I was blaming CM7, but it was actually Rom Manager that it came with).
1) setup NVflash and recovery per Roebeet's instructions, but DO NOT run the "nvflash_gtablet.bat" file (http://forum.xda-developers.com/showthread.php?t=861950)
2) download the CWM zip file (NOTE: This is for bootloader v1.1), either one from end of 1st post (http://forum.xda-developers.com/showthread.php?t=865245)
3) unzip CWM update.zip file and extract the "recovery.img" file
4) move the "recovery.img" file to the "NVFlash" directory Roebeet talks about in his instruction
5) make a new "nvflash_CWM_only_Install.bat" file with the following text in it in the "NVFlash" directory
"nvflash.exe" --bl bootloader.bin --download 9 recovery.img
you will need the entire text above including the quotation marks for nvflash.exe
6) once the ".bat" file is done, execute it with the gTablet plugged into to PC as an APX device (power plus "vol -")
7) after flashing is finished, restart gTablet with power plus "vol +" and you will have CWM back so you can ungoober what Rom Manager messed up
---------------------------
If you are having problems with windows recognizing your gTablet while in ADB, check out this thread http://forum.xda-developers.com/showthread.php?t=1056860 (my fix starts on post #8, but do read earlier posts for added info)
Another lesson learned... if your computer keeps coming up with unknown device, try plugging your gTablet into another USB port on your computer.
(thanks to Salte Droid, Roebeet, and Im_Gumby for another way to flash CWM on the post below)

Didn't quite work for me, but here's another way to skin the cat:
Follow steps 1-4 as listed.
5. Copy file gtablet.cfg and rename the copy: STOCK_gtablet.cfg
6. Edit file gtablet.cfg and find the following section:
[partition]
name=SOS
id=9
type=data
allocation_policy=sequential
filesystem_type=basic
size=16777216
file_system_attribute=0
partition_attribute=0
allocation_attribute=8
percent_reserved=0
filename=part9.img
7. Replace "part9" with "recovery" on the last line of that section (without "")
8. Save file and exit editor
9. Copy file gtablet.cfg and rename the copy: CWMOD_gtablet.cfg
10. Now you should have an original stock recovery file (named STOCK_gtablet.cfg), the Clockwork recovery file (named CWMOD_gtablet.cfg) and the gtablet.cfg that will be used whenever you run the nvflash.bat file.
11. Since the gtablet.cfg file was edited to install the recovery.img, run the nvflash batch file and you will be in business.
12. To revert to stock recovery, copy and rename STOCK_gtablet.cfg to gtablet.cfg (or redit the file to match as shown in step 6)

I have been into modding my android phones and have now just picked one of these up so please excuse my ignorance. Why should you follow this instead of following the wiki link here. http://wiki.cyanogenmod.com/index.php?title=Viewsonic_G_Tablet:_Full_Update_Guide is it a better idea to flash this way or according to the wiki. I will be getting my GTab within the next week so I would like to know. Just like with my Thunderbolt I really want it to be modded with a custom rom by midnight of the night I get it.

Well here's why I had to do this...
I tried out Roebeet's honeycomb rom, which looks very promising but is still to alpha release for me to run as my daily rom. And in order to run this rom (and a couple others), you have to move from rom branch 1.1 to 1.2 and you can't do that via clockwork recovery... you need to do it via stock recovery.
I stock recovered to 3558, but it kept looping and had I thought ahead, I would have had an update.zip ready to go before I nvflashed.
I didn't, so stock recovery wouldn't do squat and it doesn't have the option to connect via usb to your computer like cwr does.
Following the steps we outlined, you will be able to use nvflash to install clockwork and then you can more easily rescue your gtab.

Alright I'm getting this. APX is basically fastboot on my phone. Basically accessing the SPL or what have you. Just another question. I have been going through the forums but It doesn't look like you update the APX screen anywhere so basically you could completely toast your rom and recovery and as long as you have APX access you have a way to recover your system.

That's it exactly

Is there no other way but to use a computer? How can rom manager change the recovery so easily in the software without booting into recovery? I also screwed my recovery with rom manager. VEGAN rc1 rom. I do not have computer access at the moment.

Nvflash bypasses everything... think of it like formatting your hard drive and installing windows from a CD. Rom manager is more like windows system recover utilities in that an operating system is there and working at a basic level. Nvflash is just a direct connection to your system partition, so yes you do need to be connected to a computer.

Thanks for the help. Will this erase my current rom? Can i save it? Just need cm.8 nothing else done. I am confused with the multiple sites to visit and what parts actually need to be done. Simple help would be greatly appreciated. This must have happened to several others. Thanks in advance.

This method just installs CWM w/o touching the ROM.

But just so you know, the instructions I provided will install a ROM.

I'm having nothing but poor luck.
I followed both ImGumby and SuperGrover's directions. When I run the .bat, it says "nvflash.exe not recognized as an internal or external command.
Also, when I try to install Clockwork mod (either the sdcard version or the internal version) I press + and power then during the Viewsonic screen it says "recovery key detected" then shows gtablet screen then shows a screen that looks like it is trying to flash but then it restarts from the beginning and boots normally with no noticeable change.

You press power and - to get to NVFlash on the tablet. You should see the VS logo briefly and then it should be a black screen. Power and + will get you into stock recovery or CWMod.

Understood. However, I was in a rush and didn't give as much detail as I should have.
When I press - and power, it goes black and from my win computer, I attempt to execute the batch file and the cmd terminal tells me it doesn't recognize nvflash.exe. I'll try it again and quote the results.
edit: it says-
"nvflash.exe" --bl bootloader.bin --download 9 recovery.img
'"nvflash.exe"' is not recognized as an internal or external command, operable program or batch file.

OK... just to try and eliminate problems, redownload both the nvflash and image files from the other thread (and make sure you get the correct OS version) and extract to the directory.
See if that solves the problem.

Thank you. Let me give it a try.

Thank you so much for simply posting this. I just bought this tab off a co-worker. He had the alpha build of HC on it and I wanted to drop it back to a gingerbread rom. I tried just doing NVFlash out the gate and got stuck in a boot loop. I got CWM back on thanks to your modified instructions, and am now off to the races!
Thanks again!

This version from cyanogenmod.com worked for me.

OUTDATED[Guide] Setting up/using adb/fastboot-unlock, flash custom recovery & root
Below is a great guide to rooting, from several sources, (mostly taken from pingvinen's "An Idiot's Guide to Flashing the Xoom" and a guide by publicanimal. and I hope it helps. You can find the links to all of the files referenced below in the Xoom Heaven thread (thanks StrifeSoldierVII!)[/I]
(New thread in General Section by Jack207407 will have all the updated links for flashing
http://forum.xda-developers.com/showthread.php?t=1443110
One Stop For ROM's, MOD's, and Root Wifi-Only and 3G/4G Models)
"What you need to do can be encompassed in these following short steps (will be detailed later on) in the following order. Each step is required before you can proceed to the next one. However, make sure that you are very very careful and don't try to take any shortcuts. That may soft-brick your device, and you may have a difficult time to explain that to your wife ... You have been warned.
HERE'S THE USUAL DISCLAIMER--I AM NOT RESPONSIBLE FOR ANY HARM THAT MAY COME TO YOUR DEVICE IF YOU FOLLOW ANY PART OF THIS GUIDE--ANY RISK IS ON THE USER!
I strongly recommend you to read the entire guide before trying. In fact, read it twice to ensure that you have understood everything. If there is weird stuff that you don't understand, don't hesitate to ask. The reason for me writing this down is that I like to document what I have learned. This is to me an excellent way to ensure that I will remember what I just did. Another reason was that I could not find a single thread that encompassed all steps required. There are many different threads, but no one (that I could find) that really guides you from start to goal. So enjoy and good luck!
I would like to thank LandMaster and cam30era for helping out with advice during my initial trail-and-error session. I soft-bricked my device once and had big problems to get by point 4.3 (avoid overwriting of CWM), but with their encouragement I finally succeeded.
Just a note before we begin: the different Xoom. Models that are able to use this guide are the following:
MZ600 - stingray_cdma - Motorola US 3g Xoom (technically this device is stingray as well, but I will be using stingray_cdma as the two devices have incompatible software)
MZ601 - utms_everest - Motorola EU 3g Xoom
MZ602 - stingray - Motorola US 4g Xoom
MZ604 - wingray - Motorola Wifi Xoom
(thanks solarnz!)
___________
Overview of the 6 required steps
1. Install Motorola USB drivers for your computers (for USB connectivity) 2. Install Java SDK and Android SDK tools (for adb and fastboot commands) 3. Unlock the device for flashing (allowing replacement of recovery and boot images) 4. Install a modified recovery image (ClockWorkMod recovery for Android) 5. Root the device (Allow r/w access to the device filesystem) 6. Flash a kernel that supports overclocking etc.
Steps 1, 2, 4, 5 and 6 require that you download install, image and zip files needed for the flashing.
All this was performed on a Windows PC. Windows 7, Mac and Linux users will probably have to do some steps differently.
1.0 Install the latest Motorola USB drivers
The installation file can be found at: http://developer.motorola.com/docstools/USB_Drivers/
1.1 Install the drivers and ensure that your Xoom is recognized by the computer
2.0 Installation of development software
Android SDK and Java SDK need to be installed. You can find the installation kits here.
http://developer.android.com/sdk/index.html In case you can't find fastboot.exe, look for it here (thanks to jerrycycle): http://forum.xda-developers.com/showpost.php?p=19546334&postcount=5
Update: you could also just install the adb fastboot pack here:http://www.android.net/forum/downloads.php?do=file&id=67
http://www.oracle.com/technetwork/java/javase/downloads/index.html
2.1 Install them as any other software, making an Android SDK folder on C/.
2.2 Make sure that all the files you need are in the Platform Tools folder (fastboot, recovery image file and so on). Copy any files in the Tools folder to the Platform Tools folder if necessary. Note: If the Android SDK complains that the Java Dev Kit can't be found, just press Back and then Next again. Wierd, but that seems to do the trick ... go figure.
(Warning: Never put any zip files in your Platform Tools folder. Flashing zip files through fastboot will cause very serious problems. Zip files must be flashed from the external micro SD card through CWM recovery on the Xoom...we'll get to that later.)
2.3 Test that ADB and FASTBOOT works. You should open a command window by right clicking in your Platform Tools folder where all of your files are, plug in your Xoom to your computer with your Motorola cable (it may not work with a generic cable) and write 'adb devices'. Your Xoom should now be listed. Did your device not show up? Make sure that you have USB debugging enabled in Settings/Applications/Development on your Xoom.
Optional: Those that want to be able to access adb from any where on their computer, here's a tip from scsa20: "For windows, if you go into System Properties and choose Advanced, then Environment Variables..., you'll be able to edit the Path variable under System variables, just add the path to where adb and fastboot is located (separated with a semi-colon ().
Here's what my Path variable looks like:
C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;%SystemRoot%\system32;%Sy stemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\ System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Windows Live\Shared;c:\Program Files (x86)\Microsoft SQL Server\100\Tools\Binn\;c:\Program Files\Microsoft SQL Server\100\Tools\Binn\;c:\Program Files\Microsoft SQL Server\100\DTS\Binn\;C:\android-sdk-windows\tools;C:\android-sdk-windows\platform-tools;C:\Program Files (x86)\Common Files\Acronis\SnapAPI\
It's long but do you see the android stuff there at the end?"
Update: xda poster Mandelbrot Benoit suggests an alternate adb setup, here: http://forum.xda-developers.com/showpost.php?p=18072572&postcount=50
If your windows computer doesn't see your Xoom, consider this (Originally Posted by AngryBulleteyeTruth):
When the xoom does not show up on PC it may be the problem of.... windows media player!
Xoom uses drivers of WMP to communicate with PC. If someone does not have the newest WMP drivers it will not show up and you can see xoom device in the devices tab on PC having an exclamation mark.
So the solution is to download and install Windows Media Player 11. It has worked for me.
--------
OK. Now that you are set up, it's Showtime! Take a deep breath...
3. Unlocking the device for flashing
This step will effectively erase the internal storage, including all your apps and settings. Use whatever backup you want to secure important data before you start. (It will also void your warranty, so you still have time to go back.)
3.1 Power up and start the Xoom.
3.2 Ensure that your device is fully recognized by the computer. A good sign is that the 'Portable device' dialog is activated on Windows when your Xoom has booted. The Xoom should also be seen in 'Computer'. If not, go back to step 2 and double check your USB drivers.
3.3 Use the command 'adb reboot bootloader' to go into Flash mode.
3.4 Use the command 'fastboot oem unlock'. This will trigger a dialog on your Xoom. Follow the instructions on the screen to complete the unlocking. I repeat, this *will* do a factory reset and all data will be lost!
3.5 Once unlocked, the Xoom will restart and work as normal. Don't bother to do any setup at this time, just make sure that USB debbuging is checked in settings, and now go on to step 4
4. Install recovery image (CWM) UPDATED 4/19/12
If you haven't done it already, download the recovery image file and save it to your computer in the Platform Tools folder.
(Download the recovery image from this link: http://forum.xda-developers.com/showthread.php?t=1604014 only the img file flashed through fastboot Remember, never try to flash a zip file through fastboot!)
Important: At this time, make sure you have a good (known to be working) microsd card in your sdcard slot in your Xoom. Reboot the Xoom with the sdcard in the slot to make sure it's mounted.
4.1 Boot into flash mode with 'adb reboot bootloader.'
4.2 Install your downloaded recovery image: 'fastboot flash recovery eos-recovery-r6.img' or whatever is the exact name of the recovery img file you are flashing.
4.3 Enter CWM recovery with the procedure below.
4.4 Restart the device with 'fastboot reboot'. Timing is essential here, so be alert when the device restarts, or you will have to redo section 4.
4.5 Once the Motorola logotype is shown, start counting to 3. At 3, press the Volume Down button. This should result in the text 'Android Recovery' in the top left corner. If it does not work (if you see Starting Fastboot Protocol), experiment with the timing (see below).
4.6 When 'Android Recovery' is shown press the Volume Up button. This should invoke the CWM recovery menu. If that works, then congratulations for getting this far!
Here is a potential pitfall. If you are unable to enter CWM *before* the device boots into Honeycomb, then the newly installed recovery image will be overwritten by the system default recovery. Just repeat steps 4.1 through 4.6 if that happens.
UPDATE(12/28/11) Since putting this guide together, Motorola has issued a number of Over-the-Air (OTA) updates that have complicated the process of flashing the Clockawork Mod recovery, so if you have accepted any OTA updates, please read the following, which describes each step (http://forum.xda-developers.com/showthread.php?p=26009191#post26008083) (Thanks to Landorin.)
(If you have root and want to remove these files, remove or rename /system/etc/install-recovery.sh with something like root explorer. You can then flash your custom recovery through fastboot again.)
For those of you that get stuck with some error like 'device not recognized' poster Madjinj gives the following advice:
1) Be sure that you have your adb folder in the root of C drive directly and be sure that you are in adb folder in command prompt program (CMD in Windows machines) i.e by typing "cd c:\XXX" where XXX is the name of adb folder in your machine.
2) Be sure that you type "adb reboot bootloader" in comand prompt to activate adb program. if the problem persists, try typing "fastboot reboot" then after reboot type "adb reboot bootloader" in command prompt program.
3) Use the USB cable that came with your Xoom (some cables are not good in flashing for unknown reason..!!
4) make sure that you activate USB debugging mode.
5.0. Rooting the Xoom
The Universal Xoom Root zip file from solarnz is located here: http://forum.xda-developers.com/showthread.php?t=1242241
5.1 You need to transfer the Universal Xoom Root zip file to a working external micro SD card. You can do this on a computer or cell phone, but the Universal Xoom Root zip file must be located in the root directory of the micro SD card.
5.2 Insert the now prepared SD card in the Xoom.
5.3 Boot into recovery (as described in 4.3). Navigate using the volume buttons and press the power button to select the active option.
5.4 Select 'Install ZIP from sd card.'
5.5 Select 'Choose ZIP.'
5.6 Navigate to the ROOT zip file with the Volume buttons and select it with the Power button. Confirm that you want to install it.
5.7 Everything should indicate success, so back out to the main CWM menu and reboot the device.
5.8 From Android Market, install any app requiring root and start it. If the rooting was successful, then the app should request superuser permission and you should be able to grant it without any problems.
6. Flashing a new rom or kernel...(e.g. Tiamat Moray Rom and/or Odachi Kernel). Look in the Xoom Heaven thread or in the Development section of this form for all of these files.
6.1 This step is identical to 5, but swap out the ROOT zip for the ROM or KERNEL zip. For simplicity, you may want to prepare the micro SD card with both zip files at the same time in step 5.1..."
------------------------
This is still one of the best explanations of how to use adb and fastboot to unlock and root the Xoom and install a custom recovery, etc, and doesn't deserve to buries on back pages of this forum. Hopefully, the step-by-step nature of this guide will help those of you that have limited experience with this kind of tinkering.
Oh, and please feel free to correct any errors or omissions. As I said, it came from several sources and needed to somewhat updated.

Thank you, just bought my xoom yesterday and was confused on the steps to take!
This has made it as clear as possible for me and will follow your instructions to the letter tonight.

Check to make sure that your file download is good, and that you are typing it's name correctly. Better yet, you could rename the file "recovery.img" and that will make it very easy to get it right.

On the sd card?I thought we had to put it into sdk platform tools? I have put it and renamed it onto my sd card but what is the command to flash recovery from sd card?
Also noticed once I have done "adb reboot bootloader" my computer doesn't see the XOOM properly, is in can't see it in my computer but does make a noise when I connect and disconnect is this correct? Debugging is on.

When you're in the bootloader, you won't be able to access the SD Card or anything of that sort and adb won't work, in stead, when you're in the bootloader, you're switching over to fastboot. I'm sure if you type in fastboot devices you'll see your xoom listed.

Thank you for the reply and that's one thing sorted but any idea why its telling me "cannot load recovery"? I have tried renaming it and downloaded the recovery file 4 times incase that was wrong but still no joy :-(
I have done this all before on my phone and never had a problem so I must be missing something but f$*@ed if I know what?
Thanks again for your help though.

Just had a thought. Could it be that the XOOM hasn't actually unlocked, would that cause it to not load? Is there any way to check if its unlocked successfully? Although I did try it twice before?
Sent from my MZ604 using xda premium

Once you got it in the bootloader, you gotta make sure you do fastboot oem unlock, press volume down then up, press volume down again then up again, and let it format and reboot.
If it's already unlocked, you'd get a message telling you so (generally).
Then when you go to flash the recovery, make sure that the recovery image is in the folder where fastboot is and type in fastboot flash recovery recovery.img (if I remember the syntax that is, I'm at work and don't feel like scrolling up or going into the root guide to confirm xD ).

So, I don't know if you had any progress, but not successfully unlocking would surely stop you in your tracks.

With the way I have my system setup, I can run adb and fastboot wherever I am

Care to share???
That would be helpful to many, I'm sure. We could add it to the guide, along with anything else you can think of.

If, as you follow this guide, you find any explanations that are not clear or if you think of a step to take or something else that might improve the guide, please post it and we can add it in. It's been almost 6 months since I've unlocked and at least a couple of months since I've had to use adb, so I'm sure I've forgotten some things. Those of you whose experience is fresh can give really good advice. That's how this guide was originally written, by pingvinen, right after he had gone through a grueling rooting process.

For windows, if you go into System Properties and choose Advanced, then Environment Variables..., you'll be able to edit the Path variable under System variables, just add the path to where adb and fastboot is located (separated with a semi-colon (;)).
Here's what my Path variable looks like:
C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Windows Live\Shared;c:\Program Files (x86)\Microsoft SQL Server\100\Tools\Binn\;c:\Program Files\Microsoft SQL Server\100\Tools\Binn\;c:\Program Files\Microsoft SQL Server\100\DTS\Binn\;C:\android-sdk-windows\tools;C:\android-sdk-windows\platform-tools;C:\Program Files (x86)\Common Files\Acronis\SnapAPI\

It's long but hey, see where the android stuff is near the end?

@Okantomi:
We all have learned some things from trial & error (eg.the sk cannot detect java dev kit)
i could only flash recovery after renaming it to recovery(do not forget to add.img in cmd while flashing).also the official motorola name recovery as same.
after downloading sdk and updating to platform tools i have kept a zip in safe location so that i do not need to download again platform tools if i install sdk fresh
initially knowledge was scattered now it is at one place.
right now testing steady hawkin's kernel and new recovery
btw good signature pic.

Ok so another night has gone and still can't get recovery on!! Tried re unlocking the XOOM and every time it comes up with "cannot load recovery.img" I tried installing everything on my laptop and went right from the start and getting exactly the same thing!
Starting to think im never gonna get this sorted now :-( just feels like the XOOM isn't unlocking? Every time I go through the unlocking process it never states that its already unlocked? Is there any way I can check that it is unlocked?
Please help im losing the will to live now lol

I would say to send it to me and I can take a wack at it but I don't think you want to wait that long to simply root it.
Let me ask you, are you getting any sort of error messages when you do fastboot flash recovery recovery.img? If so, what's that error message?

Not getting any error message it just says "cannot load recovery.img"
I have tried with and without the .img and always the same?
Tried going through the whole process again on my laptop incase I had missed something but exactly the same.
When I unlock it I follow the onscreen instructions and at the end it says its complete before it reboots. Then I turn on usb debugging again and reboot bootloader all ok but won't let me load the new recovery?
Normally I would just say it wasn't meant to be and leave as it is but I wont be beaten on this so I'm purposely not installing anything on it till its done. Any ideas apart from bringing it round yours lol ;-)

Refer to this guide for root. It's free.
(ROOT) ZTE Blade Z Max Z982 Free Non-UAT 2/21/19

My phone is B25 Not B20. Do you got one for my specific firmware?

The patched boot and recovery are from b20. They are working fine on my b25 system image.

Any ideas how to get the UAT for free?

Here is the MetroPCS B25 full partition update.zip designed to be flashed via recovery

Here is some early production firmware use at your own risk

Pulled these from a paid site to update my device, and maybe get a firehose for you guys in the process but no luck.

After you flash your phone will try to boot. It probably will probably boot loop. The reason being, your current system in encrypted. So here is a list of what you have to do next.
1. Disconnect your phone from the computer.
2. Press and hold Vol+ and power until the phone restarts and vibrates. Then release power while continuing to hold vol+.
3. You will boot into TWRP. Swipe to allow modifications.
4. Select Wipe
5. Select Format Data
6. Type yes and then blue checkmark.
7. Back out and select reboot then system.
Mission Accomplished
The phone will do a the intial setup and you will have to open magisk manger which will then prompt you to install it.

why not using [adb reboot edl] command to boot directly into edl mode instead of using zte tool.

It seems from what I could find online the file we need from uni is called 8936_020.ufl
I'm not 100% certain though

I think we have to make one.
https://cellphonetrackers.org/wp-content/uploads/8x60_msimage.mbn_.txt
How to generate the 8660_msimage.mbn
8660_msimage.mbn is released in SW by default, actually, it includes the all the boot images and partition table there. MPRG8660.hex will download this image and reset to mass-storage mode. If customers have different HW settings, such as GPIO/DDR, the default 8660_msimage.mbn may not work for them, so customers need build their own 8660_msimage.mbn by themselves with following ways.
1. Have the QPST 2.7.366 or higher version installed.
2. Make a local folder, copy sbl1/sbl2/sbl3/rpm/tz images to this folder.
3. copy the emmcswdownload.exe from C:\Program Files\Qualcomm\QPST\bin to this folder.
4. Prepare the partition_boot.xml as below and copy the partition_boot.xml to the same folder as above.
<?xml version="1.0"?>
<image>
<physical_partition number="0">
<primary order="1" type="4d" bootable="true" label="SBL1" size="1000" readonly="false">
<file name="sbl1.mbn" offset="0"/>
</primary>
<primary order="2" type="51" bootable="false" label="SBL2" size="3000" readonly="false">
<file name="sbl2.mbn" offset="0"/>
</primary>
<primary order="3" type="45" bootable="false" label="SBL3" size="1500" readonly="false">
<file name="sbl3.mbn" offset="0"/>
</primary>
<primary order="4" type="5" bootable="false" label="EXT" size="1000000">
<extended order="1" type="47" label="RPM" size="1000" readonly="false">
<file name="rpm.mbn" offset="0"/>
</extended>
<extended order="2" type="46" label="TZ" size="1000" readonly="false">
<file name="tz.mbn" offset="0"/>
</extended>
</primary>
</physical_partition>
</image>
5. Run the emmcswdownload.exe tool to create OEM boot image with a command below.
emmcswdownload.exe -f 8660_msimage.mbn -x partition_boot.xml -s 1G -g 4M
6. The 8660_msimage.mbn will be generated in the folder.

Additionally, I dumped the usb packets going from uni to my phone while flashing splash.img. It has the loader and the splash.img in it. But it needs to be pulled out. If anyone is capable, try it. uni_usb_dump_z982.7z

The firmware you provided only have Sbl1, it doesn't have sbl2 or sbl3. Can you help me? And one more thing do you have root on your Z982 because I think I found where the firmware is in the phone and we can copy it and keep it. I can't do it because it gives me access denied of course I don't have root but I think a person with root can do it.

The Z982 has 1 sbl. "SBL1"

Did you already root your phone?

Yep

Can you try something for me real quick? Plz

How to get the partition_boot.xml? Plz help me I need my phone root as fast as possible

I have just about as much an idea on how to do it as you do.
