Flashed Build HWI69 for US Retail on a Canadian wifi MZ604 xoom..tired of
waiting for 3.1 update.
adb reboot bootloader
fastboot oem unlock
adb reboot bootloader
Xoom will then reboot into bootloader screen
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock
fastboot reboot
It is stuck on Starting RSD mode 2.
I can not get it to fastboot protocol...device does not turn off.
Any solutions?
Fastboot OEM lock is where you went wrong. Anyway see this thread.
OK I did this procedure yesterday but did not relock (I know it says to on the moto site but the guide I read said not to).
Anyway, pressing power and vol up will force a reboot. Unsure what will happen when it boots back up though...!
You should be fine. Only trying to relock will cause this error.
To get back to fastboot after a bad lock do this.
Power button and volume up, this will reboot the device.
As soon as the screen turns back on holds down power and volume down. In about 60 seconds your device should go to fastboot. Do not let go until it gets there.

Thanks for the reply . It now says Failed to boot LNX 0X0004

However it will not connect to xoom.
<wait for device> when issue fastboot command.
What the hell is going on?
you need to read this thread
http://forum.xda-developers.com/showthread.php?t=1108518
The exact thread I linked to...(-__-)'
I followed instruction from motorla dev support site.
"h**p://developer.motorola.com/products/software/?pubid=987654"
It uses command "fastboot oem lock"! So why did locking brick the device?
here it is:
Device Software Images
Select the appropriate device software image to download and re-lock your device. If you need to find your build number on your Motorola device go to Settings and About Phone or About Tablet.
The commands to flash and re-lock your device are as follows:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock
Note: If no userdata.img file is present in your download, please issue the command:
fastboot erase userdata
The Moto instructions are for locking the device back to it's own image. You are not using your device's own image. Every guide I've seen on here tells you not to relock, regardless of what Moto say. Believe the devs.
Thanxs
I now believe the devs......
Thanks for the reply. Sent the beast out to moto Canada today.

Try making or obtaining a factory cable which its different from an OTG cable. Start with the two links below. This might save the day.

So I just bought this tab. And stupidly upgraded to JB right away (not a big fan with first impression) and was following the 3 step guide for recovery and root on JB. Starting on step 3
When I reboot into bootloader from advanced, or manually (power + V down, then V down to navigate to USB sign, V Up to confirm (already unlocked bootloader of cource)
In the top left corner where the words are, the last line says "starting fastboot mode" or something like that, but nothing just stuck in the bootloader screen with 4 options RCK, ANDROID, FASTBOOT, AND WIPE DATA. Untilled I hold power to reboot.
Tried several times. What am I doing wrong?

Hi,
you are doing everything fine....
It just stays there when "starting fastboot mode" appears!
Now you can open a terminal on your pc.
When you enter "fastboot devices" (without quotes), a number will appear so you know the device will be recognized when you want to flash recovery. Just like "adb devices".
Do you have to enter fastboot devices first to flash recovery threw adb?
Cause last night after it said starting fastboot (when I thought it was stuck)
I extracted the twrp Jb recovery from same post. To the same folder as adb.exe and fastboot.exe (named the folder fastboot on the C drive) shift + right click on fastboot folder - open in command prompt
fastboot -i 0x0b05 flash recovery tf300t-jb.blob
The responded was like can't complete command. File or folder doesn't exist (or something like that, will try again when I get home with the exact response)
And tried extract to a folder named, recovery1 on my c drive
C:\recovery1: fastboot -i 0x0b05 flash recovery tf300t-jb.blob
Still with the same response
Thank you for the help

Hello,
I have followed a tutorial for solving the problem of "Fastboot mode started
udc_start()" from this thread http://forum.xda-developers.com/showthread.php?t=2131247 and something was go wrong.
I have done this steps in the sdk platform tools folder:
1- fastboot erase recovery
2- fastboot flash recovery recovery.img ( here i've got an error)
3- fastboot reboot
Everyting was ok until I have tried to write the .img file on the phone. I've got an error that I don't have enough space. I think I have deleted the recovery file and now it's stuck, because it's not booting. The 4 leds from the bottom it's flashing continuously and the screen remains to the LG logo. I have tried to connect the phone to the PC but the device it's not recognized anymore. I get this message in the adb tool "Waiting for device"
I really appreciate if it's someone that can help me
I have a p500 and I had the exact same problem as you. But I was able to fix it after a lot of Googling.
Can you get to fastboot right now? If so, make sure that the recovery you downloaded is correctly named "recovery.img" and is placed in the same folder as adb.exe is located. After that, type:
Code:
fastboot devices
into ADB. If your device is listed then proceed and type:
Code:
fastboot flash recovery recovery.img
If nothing comes up when you ask it to list fastboot devices you need to delete all of the drivers associated with your p350, and then reinstall them using a toolkit or PDAnet. Then go back and try fastboot devices again.

Can you pull the battery and then use the combination to get into Fastboot? If you can't get to fastboot, then the problem is beyond what I'm capable of doing.
Though, the problem may be that you completely deleted your recovery.

That is incorrect. The recovery does NOT have to be named recovery to use fastboot to flash it, although it does make life simpler
Hi, my son's oneplus one mobile will not start up. When we press the "on" button, we see the first "1+ powered by android" screen, then the word "cyanogen" is written across the screen. This word continues to slowly blur and un-blur slightly, but the system never comes any further. (The phone is fully charged).
We can also boot to a "cyanogen recovery" screen, where there are several options - where I guess a "factory reset" could be worth a try. If we do a factory reset, is there any way to maintain installed apps, and especially "progress" in these apps?
Thanks for any help,
Peter
You could try to use adb to backup the data, but you wont be able to save the progress in the apps I think, some apps have their progress stored online with your google account(Clash of clans for example)
ok, thanks (I don't know what "adb" is, but I'll google it).
Otherwise, has anyone seen this startup problem before, and are there any good solutions?
Thanks.
Hmm, seems that "adb" requires installation and/or enabling on the phone - as I can't start the phone, I don't think I can use this unfortunately.
You don't have access to adb unless it was previously enabled. Can you shed some light on what caused this situation please? It makes it a lot easier to troubleshoot. Do you know what build of Cyanogen OS was installed on the phone before this happened?
Hi, thanks for the reply. The phone's battery run out and the phone shut down. The power supply was attached, and it was attempted to turn the phone on - but this resulted in the current state where the phone stops at the "cyanogen" screen. The phone has since been charged over night, but will still not start. As to the current OS version - we are unfortunately not sure. My son says he last performed an OS update a few weeks ago.

Ok, thanks. If you can get into the stock recovery you should try flashing the latest build from here, then reboot the phone.
Thanks for the suggestion - but what do you mean with "stock recovery"? We can get to a menu with these options:
reboot system now
apply update
wipe data/factory reset
wipe cache partition
wipe media
reboot to bootloader
power down
view recovery logs
Can we use one of these to upload a new OS to the phone?
"Apply update" gives the options:
apply from ADB (does this mean adb *is* running on the phone?)
choose from internal storage
"Reboot to bootloader" results in a screen where it says "fastboot mode", but gets no further than this screen.

That's the stock recovery. The "apply from adb' option is present whether you have adb enabled or not, so that's a no-go. I've just realised that you won't be able to use the recovery to flash the zip anyway, because there's no way to transfer the zip to the device without adb.. I think your only option will be to unlock the bootloader and flash the stock images with fastboot. Unfortunately this will erase all data on the phone, but right now you don't really have any other option. So what you'll need to do is this:
1. Install adb/fastboot onto your PC, the 15 seconds adb installer is probably the easiest option for this.
2. Use the reboot to bootloader option in recovery to put the phone in fastboot mode.
3. Navigate to where adb.exe and fastboot.exe are located on your PC, hold shift and right-click, then select open command prompt here.
4. Make sure your phone is connected to the PC via usb cable and (in the terminal window that popped up after the previous step) issue this command:
Code:
fastboot devices
It should return the serial number of the device, if it does you have a working fastboot connection. If it doesn't return the serial number you might have to play around with drivers.
5. Once you know you've confirmed that you have a working fastboot connection you can check the status of the bootloader with this command:
Code:
fastboot oem device-info
There will be a few lines of text. One of the lines will be 'bootloader unlocked: true/false". If it says true you can move on to step 6, if it says false you will need to unlock it with step 5a.
5a. Unlock the bootloader with this command:
Code:
fastboot oem unlock
The phone will automatically go through the unlock process, and will probably try to boot into the OS. Get back into fastboot mode by using the option in recovery, or by shutting the device off by holding the power button and then using the fastboot mode button combo (hold power + volume up).
6. Once you know you have an unlocked bootloader you can now flash the stock images to the device:
-Download the latest stock images to your PC from here. If you don't want the latest build you can find all stock images mirrored here thanks to @Spannaa.
-Unzip the file you downloaded and put its contents into your fastboot folder (the same folder that you have adb.exe and fastboot.exe located in on your PC).
-Open a command prompt from within your adb/fastboot folder (shift + right click, select open command prompt here).
-Issue these fastboot commands:
Code:
fastboot flash modem NON-HLOS.bin
Code:
fastboot flash sbl1 sbl1.mbn
Code:
fastboot flash dbi sdi.mbn
Code:
fastboot flash aboot emmc_appsboot.mbn
Code:
fastboot flash rpm rpm.mbn
Code:
fastboot flash tz tz.mbn
Code:
fastboot flash LOGO logo.bin
Code:
fastboot flash oppostanvbk static_nvbk.bin
Code:
fastboot flash boot boot.img
Code:
fastboot flash cache cache.img
Code:
fastboot flash recovery recovery.img
Code:
fastboot flash system system.img
Code:
fastboot flash userdata userdata_64G.img
or fastboot flash userdata userdata.img if you have the 16gb model)
Please note: flashing the userdata will wipe your internal storage (your virtual sd card). It's possible to flash these images without that command if a full wipe isn't completely necessary in your situation.
-Reboot your device with this command:
Code:
fastboot reboot
-It's now safe to disconnect your usb cable.

Thanks heaps for the info. My son has now re-established his telephone - though he lost all his data/progress/photos etc.. Is there a recommended backup mechanism for the OnePlus One? (Maybe he can run a backup application on his PC once a week which takes a snapshot of his phone?)

The best way is by creating a backup with TWRP recovery. You'll find instructions on how to flash it (and how to make a backup) in my guide thread:

1. Stay calm.
1.a You cannot root your phone without unlocking bootloader.
1.b. You will need to do a thorough reading of how to unlock bootloader from threads in this forum or else where. You will also need to read and understand the process of fastboot mode of flashing stock firmware.
2. Since you are able to enter fastboot mode connect your mobile to your PC with your USB chord, open the minimal adb fastboot mode, try to get the unlock key, visit Motorola site and get your bootloader unlock key. There are other threads explaning how to do this. Download the correct stock firmware identified based on the phone model no. Eg xt1550 dual sim and store it onto your PC, you will also need the minimal adb fastboot file, Motorola drivers, twrp3.0., SuperSU 2.62-3 ( no other version of SuperSU works, only this version)
3. Once you unlock your bootloader, flash the stock firmware which you need to download from other thread of this forum using fastboot mode. Note, marshmallow 6.0.1 has 7 sparsechunk files. So be careful about fast boot commands. Do not use the commands you find on the stock firmware thread blindly as these have commands only for 6 sparsechunk files. You may open the flash file from the downloaded firmware to get an idea of all the commands to be typed and their respective partitions too.
4. Flash twrp to replace stock recovery. Enter recovery from fastboot mode using volume keys to navigate and powerkey to select.
5. Once into twrp, press mounts tab and tick to mount USB storage, and copy the SuperSU 2.62-3 file into the external memory card of your phone from pc. Install this SuperSU.zip file without unzipping it by pressing the install tab in twrp home screen and selecting the zip file and sliding the installer.
6. Reboot system. Done! You have your phone rooted the perfect way.

Dear friend,
You need not have your bootloader unlocked to flash factory firmware
Quote from the XDA forum factory firmware link:
"Frequently Asked Questions:
Can I restore Factory Firmware if my Bootloader is locked?
Yes."
And if you are still stuck with a phone stuck at logo or is looping at the boot, either follow steps given elsewhere in this forum or follow the method that I am enumerating below which is what I would have done (which in principle is same as given elsewhere).
Getting your phone revived is your first priority. Unlocking bootloader and rooting is secondary.
You would be needing a pc with administrator privilege, internet connection and of course your phone along with the usb cable.
You would be needing the drivers for your phone, minimal adb and fastboot files, stock firmware for your phone model. All these files are available in the XDA forum as per links provided by others or as per this link
http://forum.xda-developers.com/2015-moto-g/general/guide-fastboot-flashing-factory-t3187750
1. Correctly install drivers onto your pc using administrator privileges.
2. Unzip and Install the minimal adb and fastboot files onto your pc into some specific directory and click the executable files once. This would ensure that all the files are loaded and dos prompt recognizes the adb and fastboot commands (commands are different for ADB stage and FASTBOOT stage, what you are going to use is directly the fastboot stage commands given below). Install as an administrator. Note this specific directory and file where you unzipped and installed the minimal adb file as you will need it in the below step.
3. Download the stock 6.0.1 mm firmware for XT1550 from the link below store it in you pc.
http://forum.xda-developers.com/2015-moto-g/general/index-moto-g-factory-firmware-images-t3169639
Unzip the stock firmware. Now copy all the files of the stock firmware (all of them) into the specific file of the minimal adb and fastboot which you unzipped into and installed earlier and noted the location. You need to copy all the firmware files into the minimal adb and fastboot directory as that way you avoid specifying the location of the files for each flash command which is both simple and saves us from a lot of mistakes.
4. After copying all the unzipped stock firmware files in the minimal adb fastboot directory, press the shift button on keyboard and right click the mouse on the screen where in a dialogue box appears and choose to open the command prompt in this directory. This will open a command prompt with default reference to the current directory.
5. In what ever condition your phone is in (other than the fastboot mode), press simultaneously the volume down key + power button together for about 8-10 secs. This action will automatically lead your phone to enter the fastboot mode. After entering the fastboot mode you can connect the phone to your pc using a usb cable and your pc should ring a note that it has detected the phone. To check if the pc has detected the phone and the link is established, type the following command in the command prompt window which you opened in step 4
fastboot devices
This command displays your device number if all is well in the command prompt window. NOW you are ready to flash the stock firmware I.E. after successful detection of the phone by your pc.
6. Carefully type each and every of the commands in italics or copy and paste them ONE by ONE and wait for each command to be executed. The commands are being given below to help you (these are for flashing the 6.0.1mm onto the XT1550 only) in the opened command prompt window (Ensure that you do not miss any of the commands and follow the order given below) :
fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash system system.img_sparsechunk.6
fastboot flash system system.img_sparsechunk.7
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot erase customize
fastboot erase clogo
fastboot oem fb_mode_clear
fastboot reboot
If you have done every thing correctly till now you should see the command prompt returning a OKAY afer each command with the time taken for flashing each file. This should revive your device first.
After this you may try unlocking the bootloader and rooting as the next step. But be patient and retain a cool head to read first and think clearly..... you will need it a lot as is necessary for such things... good luck and happy learning!!
Follow the instructions in this thread ...to unlock bootloader and root...
Works 100%.

You need to copy all the firmware files into the minimal adb and fastboot directory as that way you avoid specifying the location of the files for each flash command which is both simple and saves us from a lot of mistakes.
4. After copying all the unzipped stock firmware files in the minimal adb fastboot directory, press the shift button on keyboard and right click the mouse on the screen where in a dialogue box appears and choose to open the command prompt in this directory. This will open a command prompt with default reference to the current directory.
5. In what ever condition your phone is in (other than the fastboot mode), press simultaneously the volume down key + power button together for about 8-10 secs. This action will automatically lead your phone to enter the fastboot mode. After entering the fastboot mode you can connect the phone to your pc using a usb cable and your pc should ring a note that it has detected the phone. To check if the pc has detected the phone and the link is established, type the following command in the command prompt window which you opened in step 4
fastboot devices
This command displays your device number if all is well in the command prompt window. NOW you are ready to flash the stock firmware I.E. after successful detection of the phone by your pc.
6. Carefully type each and every of the commands in italics or copy and paste them ONE by ONE and wait for each command to be executed. The commands are being given below to help you (these are for flashing the 6.0.1mm onto the XT1550 only) in the opened command prompt window (Ensure that you do not miss any of the commands and follow the order given below) :
fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash system system.img_sparsechunk.6
fastboot flash system system.img_sparsechunk.7
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot erase customize
fastboot erase clogo
fastboot oem fb_mode_clear
fastboot reboot
If you have done every thing correctly till now you should see the command prompt returning a OKAY afer each command with the time taken for flashing each file. This should revive your device first.
After this you may try unlocking the bootloader and rooting as the next step. But be patient and retain a cool head to read first and think clearly..... you will need it a lot as is necessary for such things... good luck and happy learning!!

My internet is not fast enough for a video upload sorry. But if you are not sure about the process you can search lost101's firmware flashing guide in general section. I have flashed it and it works.
