[10/14/2012][RELEASE][UNOFFICIAL]Stock 67.21.125 ICS FXZ[Minimal/Minimal-Standard]

Do you want the fastboot files for ics (official AT&T US)?
well its all (or almost all) here!!!
Note: This is the minimal standard that is just missing the system.img and the junk apps in the preinstall partition, we should get it with the %100 OEM official .
Also: I'm not responsible if this brick's your Atrix 2!!!
And finally, the download link:
Minimal
Minimal Standard
Cheers,
TCF38012
PS: Don't flash your own system.img this WILL SOFT BRICK YOUR DEVICE.
List of Images Needed(by priority):
1. System (DON'T USE THE SOUTH AFRICIAN ONE AND SOFT BRICK)

Reserved.

Good job man!
It's important to have an ICS FXZ.

Thanks, but it is incomplete so don't totally rely on it.

So what happens if you bork your system image? Have you tested that yet?
I do see you are looking for a system image, but I am curious how this can save you from a boot loop without that.
Nice start though.

Thanks.
I have every image now except for radio.
I'll upload the final one for the second leak when I make the most hardest part(radio.img)

You can grab it off the phone and use the ext4utils to package it up, there are few guides on how to do it for the og atrix, and you can figure the rest out from there.... that is similar to how I have done it.

Don't we have to worry about the certs on those missing img files? From my understanding, you can't just dd/cat those images and flash on anyone's phone.. and from some of our previous tests with mtnlion.. we've tried that.
Or, would everyone have to make their own images? Found this in a post by whirleyes (not sure how much weight it holds, but similar idea):
whirleyes said:
Next time you got it back from service, do
Code:
cat /dev/block/system > /mnt/sdcard/system.img
& put it somewhere safe.
It seems that you can restore own system partition backup from fastboot.
Condition :
bootloader won't check security certificate when restored from own backup
you must used moto-fastboot.exe & not fasboot.exe

I would really like to see this fxz come to life though... keep it up.

Yes that works with moto-fastboot since it does not check during flashing. Now booting those is another issue. The boot image is the one to really worry about. System image and others not so much, even the recovery image is not signed.

Right, but whirleye's was saying the certs aren't checked only if you flash your own system.img on your own phone.. or that's what i took away from it. Plus, we flashed the ICS system and boot from your phone on mtnlion's, and he came out with new CG errors.. still stuck in fastboot.
I guess this is a good place to elaborate on all of this.. if it's not considered hijacking.
@tcf38012 - has this been tested?

Right, that is why I was saying that flashing is easy, but booting is much harder with the locked bootloader checking the signature before booting, hence the cg errors from MY image on someone else's phone.

It is the partial fastboot files for ATT US 4.0.4. Nothing like a bootloader unlock or jellybean. When you are softbricked, just use these in AP fastboot and you are back to normal
Cheers!!!

I do not understand exactly how this works, please be more explicit.
Well let me know if this would work for me, my problem was that upgrading from GB to ICS 2.3.6 Official OTA, everything worked well and use the computer all day, until it froze and reboot and get stuck in the Motorola logo and back and restarted.

This may help you since it sounds like you are softbricked. At this point you have nothing to lose and the boot.img is already there on your phone. Give it a shot and if it doesn't work you may be able to take it to AT&T since it was the official OTA that bricked ya. Good luck!!!

Ok friend, another question, as I use the files that I download, Minimal, Minimal Standard? also you do with South Africa FXZ file?

Minimal Standard. All you need from the South Africa FXZ is the system.img and flash with "moto-fastboot flash system system.img". Don't flash anything else from the South Africa FXZ.
Cheers!!!

Ok to get this straight, first put the phone in Fastboot bike, then unzip the file 4.0.4_67.21.125_edison_fxz_minimal_standard, run the file and then run flash.bat "moto-fastboot flash system system.img" with the system.img? That is so true?
if this is so I could include the system.img file in the same folder and add the file. bat line "moto-fastboot flash system system.img"?

You need to get the moto-fastboot utility. Google search for it.
You use the moto-fastboot command and not the fast boot command to flash. I have used it on my macs many times without issue.... The fastboot command does not work on moto phones/images.

[Q] [Help] Razr Droid HD Maxx stuck on welcome screen

Attempted to use the RAZR HD Utility to reset back to 4.1.2 and it failed in the process I think. I rebooted the phone and now it just gets stuck on the Welcome screen. After I press continue on the welcome screen it just goes into an infinite loading of "Please wait this may take a while...". I can access the settings page from it and I know my phone is on System Version 9.30.1.XT926 Verizon en US, I am on android version 4.1.2 but the baseband version is unknown. How do I factory reset this thing or get past the welcome screen? I can access the launcher when using the Volume UP+Down and Power button to get into fastboot and recovery but I am unsure of where to go from here!
To clear anything up, I am currently unable to boot to android. I am stuck in fastboot. I attempt to fastboot the boot.img or system.img and it just hangs on writing to the device. If I attempt to use the Razr HD Utility I get:
Preflash validation failed
FAILED (remote Failure)
When flashing the system.img
When I attempt to use RSD Lite 6.1.5 it hangs on flash boot "boot.img" 15/27
All my md5sums match.

re-download the utility and flash it again. something didnt flash properly, and no reset will will fix it.

Use rsd lite & delete the lines in the xml with getvar.

you have a 926 correct?
that tool re-wrote the partitions, i dont know why it would fail after they were clean. im not sure that else to tell you to try.

which would be the last file on that page, like i said.

I have done everything correctly and when I use RSD lite v6.1.5 everything goes smoothly but it hangs or doesn't seem to progress past 15/27 flash boot "boot.img"
It seems that it doesn't want to write the boot.img to the phone.
I think I have narrowed it down to maybe a corrupt /system because it refuses to write or erase it from fastboot.

i wish i could help you but im not sure what else to tell you to try.
the only time i have seen the partition script i gave you not fix the problem is when twrp screwed up the partitions beyond repair.

If I try fastboot oem unlock I'm prompted with the unlock message and after hitting accept. I see the following error on the screen
ERROR: Failed to format UDA.
Error while unlocking device.
My next try was with RSD light. I tried flashing all of the images for my xoom off this site . all of them give me the following error:
Failed flashing process. Failed Flashing process. Interface AP-OS: Error flashing subscriber unit. Device API error: 0xE0020085 Address: 0x1F870 Command: ADDR (0xE0222085); phone connected
I ran out of ideas on what to do next. One post i saw said try using a nand backup but I can't find one that will work.
Any help would be great. I really love my XOOM and I'm sad i can't fix it.

Acer A1-830 stuck in boot loop soft bricked.....

Okay i have an A1-830 & was installing a game, made a couple of modifications & now i have a soft bricked device.
I was installing Gangstar Rio & made some changes to try & get it to run as the minimum specs, my device had to run it but @ 1st it stated that the license was invalid so i changed the date backa year on advice from someone & it worked but then it stated that the device was incompatible, so i researched & found that was happening to most with devices that should have ran it but someone had advised to make some change to the 'batch.prop' file to fool the game to think it was a different device. I may have accidentally changed something in the batch file that caused this. i can't be certain but yeh, when i rebooted my tablet it got stuck @ the Acer logo in bootloop.
I tried recovery & did a factory reset & it acted like it was working but when i rebooted my device it still bootlooped. I then did some research & i tried to flash the stock rom but got errors each time i tried. i'll list the errors below;
i started off trying to flash the 'system.gz' file as follows;

Download this to your computer and unzip it. Don't unzip the system folder in the zip file. Open fastboot and do fastboot flash boot (the boot img) then once that's done, do fastboot flash fastboot (fastboot img) then do fastboot flash recovery (recovery img) and then do fastboot reboot-bootloader. Then do fastboot flash system (system img.gz). Then on the tablet using the volume keys and the power button, go to recovery and wipe data then reboot, now it should be done!

I also have a problem along the same lines, I have a feeling I'm getting closer to solving it, but I can't seem to get it to boot.
It all seems to go well..

Then I try to start the tablet but just get a quick flash of the USB symbol and nothing else. I've tried various things but I'm not sure if I'm missing something here or not. Can anyone suggest anything? This is driving me crazy.

I am not sure but by now you must have probably fixed it but try to boot into recovery and wipe data and reboot. That usually fixes bootloops upon flashing stock roms *ehum*samsung*ehum*, never the less, it also worked for me in my acer and I am back and running!

big thanks! tablet is booting fine again

YAAAAAAAAAAAAY!!! Ah, I remember when I was stuck in a bootloop (and was a noob at android) so I took it down to the shop and they gave me a new one, then it happend again and I got another one for free! But as always, I'm so glad it worked!

I'm also having the FAILED (remote: flash_cmds error!) error. I have tried to do the steps in the specified order in the comments and I still get the error.
Can anyone help me?

Reboot droidboot and try flashing the 4.2.2 image, also, try flashing in this order (boot, fastboot, recovery, system).
Hit thanks if I helped.

Is the 4.2.2 image the Acer_AV0K0_A1-830_1.006.00_WW_GEN1_FLASHPKG version?
If so, I got the exact same error.

Have you wiped data? Also, reboot droidboot and make sure fastboot recognizes the device. Maybe you can try adb pushing the files via fastboot oem startftm command.

How are you trying to access droidboot? You can't hang on logo if you don't have droidboot (it's the bootloader mate).
