Make sure you are running the most recent CWM (1.7.2 or 1.7.3)
Boot to recovery, and this time, do all your wipes
Wipes Menu
a. wipe Data/factory reset
b. wipe cache
c. wipe Dalvik
Go to Mounts and storage
a. Format system
b. Format Flexrom
Install rom, and make sure it's a rom with an ICS kernel.
As a last chance if the above normal things don;t work,
you may have corrupted data somewhere, and in this case, go to Backup and Restore and toggle Data Media. NOTE: This will wipe your tab clean of fotos, music, etc. Everything.
Then do your wipes and formats.

I have tried the suggested and I'm still on boot loader.
ROMS I used
FLEXREAPER-ReliX-GT_Rev1 ANDROID 4.0.3
RE-FLEXxx-ShellSHOCKRev1.1
Acer_AV041_A500_1.054.00_WW_GEN1-DEODEXED-FULLROOT
Also on CWM1.7.3 latest
Wiped everything twice and didn't see any change so should I try a stock Rom and just revert to non root ?

You can also wipe userdata from fastboot: "fastboot erase userdata". You may try using adb after a while and do logcat, from where you can see what's the issue.

OK I can't seem to get my tab on fastboot mode and I haven't used adb to get a logcat so is there a thread that talks bout how to do that.

you type in command from PC.
open cmd prompt from where u have fastboot.exe
type: fastboot devices
u should see a ?
then type: fastboot erase userdata
it should then tell u userdata erased.
u can also flash recovery.img with fastboot and get yr cpuid....very useful

You have to have the Android SDK installed on your PC.
Then you will find it in Program Files (or Program Files (x86))/Android/Android-SDK/Platform-Tools/ There you will find fastboot.exe

You probably got "java' is not recognized as an internal or external command."
You still need to install the Java dev kit. Go to Oracle, and get the Java Jdk7 and install it. (remember, android uses Java)
http://www.oracle.com/technetwork/java/javase/downloads/index.html
Then, after install, view this video to set the PATH, then do the same for CLASSPATH
http://www.youtube.com/watch?v=D13ZSPA1Ff0
You won't get that error anymore.

Okay I downloaded the java 7 and followed the process but still got errors so i went to sdk folder and did it over
I went by this video and it worked "http://www.youtube.com/watch?v=oaNM-lt_aHw"
After I got commands to work i typed fastboot erase userdata and i got on my tab "erasing uda partition then it said Done.
I used the cmd to reboot table to recovery and download a new ics rom.
It didnt work it went back to its ussal stuck on v8bootloader self. What do I do now ?

I'm in the exact same position right now. On ICS v8 bootloader, flashed latest re-flexxx rom, tablet was sluggish. Turned it off in order to restart it. Upon restart tablet froze @ "booting primary kernel." I tried everything I could as far as doing things in CWM (flashing different roms, none would get past booting primary kernel | tablet won't go into APX Mode) Tried flashing TWRP via CWM, now I can't even boot the recovery kernel.
Booted into fastboot, erased userdate. Sent fastboot flash recovery recovery.img (CWM). Said flashed SOS Partition successfully on tablet. Tried rebooting into recovery, same thing; freezes at booting primary kernel. I'm pretty sure this is the end of my A500 lol.

Sometimes certain roms do not properly either clean up the cache and dalvik-cache before and\or after installation which can cause that exact issue. It boots to the Dual-Core screen without doing anything else or restarting after some random amount of time. Hook up fastboot, connect to the device
in command prompt, type this
first confirm that fastboot can communicate between the phone and the pc by using this command below which should show a device connected and list it's serial number
fastboot devices
#--if fastboot sees your phone then just simply type
fastboot -w
#--that wipes the partitions that can cause you to get stuck at the initial boot screen logo, after it finishes, just type
fastboot reboot
I've gotta out of a few situations where phone wouldnt boot until I either did this "fastboot -w" or in clockworkmod recovery, cleared the data and cache, hope that helps, try this method before jumping to any extreme solutions that could make the phone a hat weight

ok it rebooted and went off the screen now its in a boot loop and flashes the motorola sign then shuts down and keeps going
ok, so the issue was partly the cache not being wiped prior the rom being installed and something went wrong with the installation of the kernel. That happens if the boot.img didnt properly extract and write to partition or its just incompatible with the rom\device.
Visit faux123's thread with kernels for ATT froyo, GB, CM7 & CM9
download the kernel that's compatible for your rom(froyo, gb, cm7 or cm9). Once you download the zip, go in there and pull out the "boot.img" file and put it into the same folder you have fastboot.exe in and boot into fastboot again.
quickly check connectivity with "fastboot devices" to verify and if that checks out, use this command.
"fastboot flash boot boot.img"
it takes like 3 seconds or something to complete so its an easy fix, after its done just do the "fastboot reboot" command.
i had this same exact issue last week plus my recovery was being erased along with this problem so i keep boot.img & recovery.img just sitting inside the fastboot folder just in case
atrix reboot project - it has every single file thats for the atrix and copies of systems, roms, tools, recovery files, mods, tweaks
Try this:
Pull battery
Replace battery while holding volume down until you see fastboot
Tap volume down to until you see android recovery, then press volume up to enter recovery
First try wiping cache/dalvik, if that doesn't work restore nandroid backup, if that doesn't work reflash rom

[Q] phone not booting!

So I was following all the steps from this thread: http://forum.xda-developers.com/showthread.php?t=2010312
and I did flash the stock 4.2 img. Now, after unlocking the boot loader, i didnt exit the fastboot mode and stayed in. And continued the steps of section D (all of it). Then I did a fastboot reboot , and Google appeared and below it unlocked lock and then the jellybean logo. It's been almost 20 min and it hasn't passed that screen yet. The rainbow colour X.
What do I do to fix this?? I can go back to fastboot mode, but not sure what to do. I did the fastboot erase cache before rebooting my phone!
Look at the notes of section D.
You have to reboot into recovery, clear cache and factory reset.

I did this though: 13) Erase the cache partition: fastboot erase cache
14) Reboot: fastboot reboot
Okay, and I will try to do that now.

Flash it again using fastboot and the official Google image. Recent nexus devices are strange, i never had problems before but softbricked both nex4 and 7 just like that. If you can enter fastboot mode all is well though.
Ps. That tutorial, that was the longest one I've seen in my life. Are you aware that Google images contain clickme.bat files? You literally click it and it's done. Just make sure you have fastboot and adb installed. You can extract them from nexus toolkit as well.
If you do wanna make it by hand, also no problem. Download the image from here:https://developers.google.com/android/nexus/images
And type:
fastboot flash bootloader bootloader-maguro-primekk15.img
fastboot reboot-bootloader
fastboot flash radio radio-maguro-i9250xxkk6.img
fastboot reboot-bootloader
fastboot -w update image-yakju-icl53f.zip
Exchange the correct names of course. And make sure you're in fast boot mode.

I was trying to mount the sdcard with nexus 4 but it wont do that with CWM and TWRP.
okay I think I just lost access to everything on my phone :|. I am still on TWRP, is there anything I can do with that?
I accidentally wiped the system files ugh. So I lost bootloader which means my phone is empty and useless and im still active on TWRP.
This is what I did in TWRP:
went to WIPE menu and did the following:
1)Wipe Cache
2)Dalvik Cache
3)Factory Reset
4)Wipe System
5)Wipe External storage ( didn't work - failed)
6)Wipe Internal storage (deleted)
So I have a boot loader still ?? or is that gone too? I am still active in TWRP. What are my options to fix this mess I've gotten myself into =\.

for the next time, you better learn what all this stuff is and means which you are flashing. i cant help but thinking its dangerous what you're doing there. if you are in twrp you're free to install any rom, your phone is pretty much safe if you can access it. wiping system wont kill your bootloader, system is a partition, your rom gets installed in there. you can wipe it, most roms even do it by default in the installation script. if your bootloader is gone you'll know.

Is that a Mac? There is another thread with a guy having issues flashing system.img using a Mac. Not sure if he was able to fix it or not. He was able to flash all the other images just not system.img.
For reference from Efrant's thread on flashing image files if your phone hangs during first boot try this:
Note that some users indicate that they can't get past the X on boot. If this happens to you, reboot into the bootloader and select recovery. Then, when you see the Android with the red exclamation mark, hold power and press volume up to take you to the menu. Wipe cache. If that still doesn't work, boot back into recovery and do a factory reset.
http://forum.xda-developers.com/showthread.php?t=2010312
I had the boot issue when I first flashed the images and just formatting the cache fixed it for me. I later had to do a factory reset as the phone was reporting the wrong storage size, 8 GB instead of 16 GB and the reset fixed it.
Here is the other guys Mac thread, not sure it will help you or not.

Yeah you do. I just did this on my Mac for my Nexus 4 and Nexus 7 last night with absolutely no issues.
The procedure I used is as follows...
1.1) Download the factory image and ensure all .img files are extracted to the "platform-tools" folder
1.2) Boot phone into fastboot mode by powering it down then holding volume down/power at the same time until the fastboot screen appears
2) Plug the phone into the computer via USB cable
3) Open terminal and type: fastboot devices (if it recognizes your phone's serial number you are ready to move forward)
4) Reboot by typing: fastboot reboot-bootloader (I do this just to test the connection but it's not 100% necessary)
5) Flash the bootloader: fastboot flash bootloader /Users/kevin/Desktop/Android/sdk/platform-tools/bootloader.img
6) Reboot: fastboot reboot-bootloader
7) Flash the radio: fastboot flash radio /Users/kevin/Desktop/Android/sdk/platform-tools/radio.img
8) Reboot: fastboot reboot-bootloader
9) Flash the system partition: fastboot flash system /Users/kevin/Desktop/Android/sdk/platform-tools/system.img
10) Flash the data partition: fastboot flash userdata /Users/kevin/Desktop/Android/sdk/platform-tools/system.img (Note: this command will wipe your device)
11) Flash the kernel/ramdisk: fastboot flash boot /Users/kevin/Desktop/Android/sdk/platform-tools/boot.img
12) Flash the recovery partition: fastboot flash recovery /Users/kevin/Desktop/Android/sdk/platform-tools/recovery.img
13) Erase the cache partition: either a) fastboot erase cache OR b) fastboot format cache <<== (the second option seems to work better for most people and it's what I used)
14) Reboot: fastboot reboot
After completing step 14 your phone should reboot to the initial setup screen. If you follow those steps vigorously you won't have any issues. If it doesn't work you did something wrong and should start over. If it doesn't work on a second try then I'd re-download the system image from HERE again just to be sure the .img files you are ultimately trying to use aren't corrupt somehow.

In the other walk through flash system image and boot image is replaced by "./fastboot update image-occam-jwr66v.zip". This could help those who are having problems flashing the system image file. I've also seen this method used for windows in that all you flash is the bootloader image then the update image and your done.
-w is to clear the userdata, but the problem is its not pushing the system.img on the phone! Tried without -w and yet the same issue! I have restored my previous rom and madea nandroid for 4.2.2 stock! Might go back to that and try updating ota! Can somebody confirm if i have to lock bootloader and lose root to get an update!
I have no clue why the same steps work for 4.2.2 but not 4.3 image files!

One thing I don't think anyone has mentioned (which may actually be the core solution to this problem for everyone) is that you need to update your SDK Platform from 17 to 18 and you need to install "Android Support Repository" in order for 4.3 to properly flash. To do this open terminal and paste the path to the "android" executable file found under sdk/tools. My path was:
/Users/kevin/Desktop/Android/sdk/tools/android
After pasting the appropriate path into terminal hit enter. This will open the SDK Manager. Once SDK Manager is open it will ask to update outdated drivers. One of the drivers being updated is SDK Platform. Before hitting the update button scroll down to the 'Extras' folder and check the box next to "Android Support Repository". Now hit the update button.
After doing this, reboot the computer (may or may not be necessary) and try flashing again by following the steps I provided in post #5. Let me know if that solved it.
Well, i may try that! But as if now, went to bootcamp, installed drivers and sideloaded 4.3. I may still try updating sdk, just in case i may neeed to do this again!
Where is this sdk/tools?

sdk/tools is located wherever you extracted the .zip file to. In my case I just put it all in a parent folder on the desktop called "Android".

[Q] Boot Loop (CM Recovery)

First of all, I know that there are many people asking same thing. I have checked those threads and I guess I am just a little bit more clueless. Last time I was able to use my Nexus 10 was 3 months ago. Since then I tried to solve it many times, but no luck so far. I will try to explain some of the issues I'm experiencing, but I'm afraid I'm not too good with all the expressions people are using on this forum.
1. ADB vs Fastboot
I see this mentioned often and I don't know what exactly it means. It's amazing to me that I can't google it, I'm usually good with googling. I can see that my N10 is sometimes listed under ADB and sometimes under Fastboot devices but I have no idea what I did to change that. I do know that whatever I try to do at certain point, it's always in "wrong" mode, waiting for adb etc. So if someone can point me to a thorough explanation, a wiki or something, that would be very nice.
2. The Loop
I managed to get ClockworkMod v6.0.4.3 installed and it's this loop that device is now inside. I've tried pretty much all possible combinations, wiped both caches, did factory reset, rebooted to system/bootloader/recovery... nothing. Always ends up on same CM menu.
3. Android Toolkit
I have installed this on my computer and tried so many things that I forgot about all details. I tried flashing the big 400 MB stock image to the device, but haven't been successful (says waiting for ADB, even if the device WAS listed as ADB device before I started the procedure). I am also expecting to see the N10 as another "drive" from my desktop, if you know what I mean, so that I could copy files to it. However I don't see it that way, I only see it registered as a Nexus 10 device, like a mouse or any other non-drive device. Is this normal?
So what to do? Can anyone tell me in a simple way, because I am obviously stupid enough to find threads I've seen so far not clear enough. And I would actually think that my computer literacy level is rather high, I think that this Nexus 10 is the only thing that brought me to my knees in last 20 years of working with computers.
And when I say "simple wiki style" I'm thinking of something like this:
Ok. no links allowed, great. It's a redmondpie article named
/how-to-set-up-android-adb-and-fastboot-on-windows-tutorial/
This is easy enough for me... but do I assume correctly that all this has already been done with me installing Android Toolkit? If so, it uses a different path structure and I don't see all those folders...
So u do have cmw installed, when u try to flash a ROM it just boots to recovery?

You mean flashing ROM only with CWM, not through android toolkit? Through CWM menu I have tried (many times):
- wipe data / factory reset
- wipe cache partition
- wipe dalwik cache
I don't see way to do anything with:
- install zip
- backup and restore
- mounts and storage
Rebooting menu items do following:
- Reboot system --> reboots to same CWM recovery menu
- Reboot to bootloader --> reboots to the stock bootloader "menu" where I can choose between Start, Power Off, Recovery mode (picking this will reboot to CWM recovery menu) and Restart bootloader (picking this will reboot to this same menu)
- Reboot recovery --> reboots to same CWM recovery menu
1 adb works only in os and recovery, fastboot works only in bootloader

fastboot erase recovery
fastboot flash recovery nameofrecovery.img
3try not to use toolkits, you have a nexus, toolkits are more complicated than manual methods and you won't learn anything from it
Once you have recovery
Wipe all, then you will will need to use adb sideload to flash ROM as you have no ROM on emulated sdcard
Go to advanced menu
adb sideload
adb sideload nameofROM.zip

The first part worked ok. The second part doesn't.
ADB sideload - I went there in the Nexus menu
adb sideload kitkat2501.zip
returns this:
* failed to write data 'protocol fault (no status)' *
If I do it without starting adb sideload on nexus, then it just says "error: closed", so it does recognize the change.
I downloaded the latest sdk tool, 64-bit, and the stock nexus 10 rom from 25th Janaury.
Let's do this, grab the latest stock for manta from here
https://developers.google.com/android/nexus/images
fastboot erase system -w
fastboot erase boot
fastboot erase recovery
And extract and run the flashall.bat
This should bring you to the latest official software/firmware. Then with you up and running we can root and give you custom recovery,ROM,whatever
If you have an issues at all please copy and paste all input/output from cmd/terminal here

[HELP] Moto X 2013 seems to have no OS on it

Hi everyone,
tonight I was trying to install the Stagefright OTA using this guide: http://forum.xda-developers.com/moto-x/general/xt1053-222-27-5-stagefright-ota-update-t3210786
The only thing I got was an android with a red triangle on it. So I went back, did a total phone reset, reinstalled the TWRP (fastboot flash twrp.img) and restored my backup. Sadly, the phone keeps rebooting to the TWRP as if there's nothing on it except the TWRP.
I've got the eu model and I can't find any factory image (or image in general) to flash on the device.
EDIT:
I manage to get something to work by simply boot via the "BT Tools" fastboot menu voice.
I don't exactly know why, but this way I manage to boot on a clean Android install and then restore my TWRP backup.
There's just a little problem: if I boot normally the system goes straight to the TWRP and won't boot.
I always need to go in the fastboot menu and select "BT Tools".
i was going through a similar reboot process last night. I realized that my issue was that I had xposed installed and had to uninstall it. however, I realized that after I wiped internal storage.
thus, my solution was to wipe everything (cache, dalvik, data, & internal storage), then mfastboot the stock ROM, then flash TWRP, then restore nandroid.
however, make sure to copy your nandroid to your computer first - you can transfer it back to the phone after flashing TWRP. you may have to perform a small nandroid via TWRP just to setup the right folder names, but you can still transfer the nandroid folder to your phone while the phone is in recovery.
hope this helps.

you could be missing this line: mfastboot getvar max-download-size
I used the guide here: http://forum.xda-developers.com/moto-x/general/xt1060-lollipop-5-1-ota-fxz-thread-t3139519
granted, you appear to have a different model than mine, but the process should be the same.

Yes, I skipped that line and removed it from the .xml of the images I flashed because I found some guides that suggested it.
Now I'm really tempted to re-flash everything using that command first.

All removing that line does is prevent the system partition from error-ing out during the flashing process, which is why it's suggested to remove the line if you are using RSD-Lite to flash an image

I flashed it using the -P option so I guess it's just the same as using that line, right?
Also: the removal of that line was not only in your guide so I immediatly deleted it

Flashing with mfastboot with the -P option is the same, you can verify the option exists by just typing in mfastboot in the command line, it will show you all the commands and what they do
I didn't want to have people dependent on using RSD-Lite (or any particular program) to flash the System Image, as it then makes a Windows machine the only thing possible to flash this image plus it uses Internal Moto Only software (legal issues), so I tried to find a better way to make mfastboot work properly for all types of computers
another thing I have noticed is that my phone kept getting stuck on the boot image screen (failed to proceed to the boot animation screen). to resolve this, I made sure to flash SU via TWRP after flashing my ROM via TWRP (or restoring a nandroid).

I really appreciated that (proud Linux User here), I tried mfastboot on Linux and even RSD-Lite on my Windows machine, but both of them failed to get my phone working with the files you provided in the other thread.
Now I'm stuck with this problem: every boot I need to select BT Tools and wait some minutes for my phone to boot.
I still don't get why it only boot in TWRP and I still don't get how to fix this

Yes, tried, but nothing happens (except that it boots when I go into BT Tools).
I think there's something wrong with my partition scheme because it always go straight to TWRP.
If I were on a GNU/Linux distro I'd check the grub config because it seems it boot from the wrong partition, but on Android I don't know if/how that's possible.
does it boot up when you flash the stock recovery? perhaps you may need to let it boot up first before installing TWRP?
did you happend to type "mfastboot flash boot twrp.img"? that could be the issue, as the command should be "mfastboot flash recovery twrp.img, right?
sorry I can't be more helpful, as I'm sure this is frustrating for you. just trying to grasp at straws here....

Don't be sorry, you're helping me!
Also: I'm not much frustrated since I have a working phone right now, I just need do avoid rebooting it
I tried to flash the stock recovery (found here: http://forum.xda-developers.com/moto-x/general/official-collection-firmwares-fxz-sbf-t3146628, used this: XT1052_GHOST_RETEU_5.1_LPA23.12-15_cid7_CFC.xml.zip) but if I'm not wrong (did that yesterday in the late night) it just booted to the Android with the red triangle on it (so, no booting for me).
EDIT:
No, I don't think I did that. But let's suppose I did, how can I revert it?
Also: is there a way to see my partition scheme so I'm sure everything's fine?

You can revert it by taking the boot.img from the 5.1 zip and flashing that using the command...
mfastboot flash boot boot.img
The partitioning you are mentioning is probably the gpt.bin, but that is typically done near the very beginning of the flashing process
here's what I would do:
boot into recovery
connect phone to PC, copy your nandroid and any other files from the SDcard to your PC
within recovery, wipe cache/dalvik/data/internal storage
reboot to bootloader
run the mfastboot commands as shown (but use the getvar-download....) in place of editing the xml zip file
after running the mfastboot commands, let the phone boot up to stock and establish itself
reboot to bootloader and flash TWRP
again, just a suggestion on what I would do - seems like @mastarifla is a great resource and is more knowledgeable than me, so maybe you'll get some confirmation.
good luck!
Ok, I still haven't solved this issue.
I tried with re-flashing everything, but I still get the problem.
I think it's a problem with the partition scheme because even by flashing just partition gpt.bin and motoboot.img when I launch reboot-bootloader it reboot the phone into TWRP.
I think the TWRP is in the wrong partition and/or I've got a wrong partition scheme, but I don't know how to check it or how to fix it.

So your phone thinks that the bootloader is your recovery?
That is actually pretty strange, you could take a look at the Linux kernel on Motorola's GitHub and see if it has any info on the partitioning structure or what happens when a reboot-bootloader command is sent to the phone
It sounds as if the recovery and the bootloader swapped places, as the fastboot menu is considered a part of the bootloader, and if you are not seeing that on the hardware key bootup, then there is something definitely wrong, if you do reboot-recovery does it take you to the bootloader/fastboot menu?
