I've found only one instance of this so far in the development forum by user malickie but they seem to have just returned the phone and I don't believe it's unfixable.
It all started by my trying to update while retaining root without flashing a stock 2.3.5. I tried the "three lines of code method", editing from within the phone using either FX or ES explorer (one initially wouldn't paste back into /system/bin after I made a backup on the sd card).
When I tried to update it got as far as the recovery image, the android with the folder and arrow, and eventually crashed telling me I had invalid this and that; CDROM, SYSTEM, WEBTOP. Sorry, I don't remember the specifics. I shut it down and it bootlooped as far as the AT&T logo droplet thing.
I launched into forum scrounging mode, got RSD Lite 5.6, the FXZ, the update.zip, and flashed back to 2.3.5. The first time I shut down after this it bootlooped again. So I flashed it again, so far so good, so I figured I'd go ahead and update to 2.3.6. More bad luck as it tells me "insufficient memory please factory reset". I try this, and it goes into fastboot telling me "Invalid CG (cg: recovery)".
So, I've been scrounging all day trying to figure out if this issue has been solved to no avail Does anyone have any suggestions?

I hate to say it, but it sounds like you might have a bad phone.
But you can try using the beginner thread and use the directions there to flash the fxz, but try unzipping the fxz and then go into RSD lite and click on the "..." button, and then select the xml file and start flashing.
If that does not work, there is another way, but you have to be VERY careful, because this can hard-brick your phone.
Last ditch, but ONLY if the others don't work, do this:
Make sure your have the android sdk installed:
http://developer.android.com/sdk/index.html
Then go grab this, and put in the same directory as the SDK installed to, under platform-tools:
http://forum.xda-developers.com/attachment.php?attachmentid=890596
Then open a command line in the directory that you saved and unzipped the fxz in, then;
put your phone in fastboot mode, connect the USB cable, and:
Code:
[FONT=monospace]
[/FONT]fastboot erase userdata
fastboot erase cache
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash preinstall preinstall.img
fastboot reboot
No guarantees this will work
The first two work fine, returning "OKAY". However, if I try any type of flashing from the cmd prompt I get a "FAILED".
Code:
C:\*\InlineFlashing_etc>fastboot erase userdata

OKAY [ 17.982s]

(bootloader) Preflash validation failure

finished. total time: 18.212s
I realize we have a locked bootloader so is there a step I might have missed? I flashed back the updated fxz (that's now 18 steps instead of 20, and PS. this renders me with a functional phone, just not one that can update) and luckily I can seem to get back to at least this state consistently.
Ok, so I tried rooting in this state and used the ADB method from the Beginners' Guide to attempt to retain root through the update. This time there was nothing about insufficient memory, it just downloaded the update and then tried to reboot for the install but instead of going to unzip the package it goes straight back to fastboot flash mode with another failure.
Code:
AP Fastboot Flash Mode (S) (Flash Failure)
0A.65
Battery OK
OK to Program
Connect USB
Data Cable
On the bright side it's not taunting me with invalid partitions but then again it won't boot normally either. I'm stuck on this screen.
Try pulling the battery and then booting into boot selection mode. (Press+hold volume buttons, then power button) and select "normal boot".
If that doesn't work then flash the fxz... again.
Did you do manual or one-click root?
Sent from my MB865 using Tapatalk
Ok, I had to plug it in overnight, making sure not to press the power button because it would go into "AP Fastboot", because my battery ran low. I'm flashing the updated FXZ again right now.
I've only ever done the One-Click Root. The first time I tried to retain root, what started all this, was using only the phone. This last time I used the ADB method and it didn't demand I factory reset.
Interestingly, when I tried that factory reset that's when it told me my recovery image wasn't good. I've noticed that the FXZ doesn't flash recovery.img but it does flash system, boot, and preinstall. So, is it possible I could manipulate that file to perform the steps you, Jim, suggested? I should just need to create an MD5 sum and follow the template of the rest of the time, right?

Hello,
I have the MZ601 (Xoom UK 3G) and had EOS Everest JB stable on it.
Now I wanted to go back to stock. I downloaded the original firmware from Motorola, flashed the img files with adb and everything was fine (I did not relock the bootloader). The first OTA went fine too, now I am on Android 3.0.1 (H.6.1.-38-1).
It now detects the next OTA (about 44 MB, 63.5.25.en.EU), downloads it, tries to install it but at about 1/3 of progress the green bot of ! appears. I reflashed the stock firmware several times now, same result.
Then I googled, flashed Tiamat CWM recovery, rooted the device and then did:
adb remount (got message: succeeded)
adb shell rm /system/recovery-from-boot.p (message: no such file or directory)
adb shell rm /system/etc/install-recovery.sh (no message, so guess it worked)
Now I have no idea what else to try. I'd like to get back to stock ICS.
edit: reflashed back to stock once more. This time I entered recovery mode before I applied the very first OTA and the green bot of ! already appears, what's wrong here?
Hi,
It looks like your problem is not big deal. Just try flashing again all the files and principally DON'T FORGET TO FLASH RECOVERY! And I don't see why wouldn't you lock bootloader , if you really wants it unlocked and go to stock ICS I'd recommend you to flash stock, lock bootloader and then you update, after you get to the version you want unlock again :thumbup:
Wish you the best luck
Any problems please give me an up!
Thanks for your reply!
I think I flashed recovery with the specific adb command (see below), not sure, not really an expert. :/ I even wiped dalvik cache and factory reset in cwm recovery before flashing back to stock.
Here's what I did in detail when reverting to stock:
I downloaded MZ601_H.6.1-38-1_Retail_Europe.zip from the official Motorola website, extracted all files and used these commands in adb:
Code:
adb reboot bootloader
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
Also, I noticed the green bot of ! appears after reboot when I enter recovery mode even before I flash the very first OTA (so just after flashing the stock files and reboot). Looks like recovery is somewhat broken or so?
I didn't want to relock the bootloader simply because I might want to root the device once I am back on stock ICS. Basically, I just wanted to get away from a custom ROM (Team EOS).
Would locking the bootloader make a difference for my success? According to google it doesn't but I am no expert to judge it right.
Yea, it looks like something is going wrong there...
Try downloading the files again, and then flash recovery. If you have no success try locking your BL, maybe it can works. The two times I went back to Stock I relocked my BL and had no problems to update via OTA. Then you relock your BL and use LordAIOTool to root again, which can easy your work...
Also you should try erasing system, recovery, cache and data before flashing, but it looks like what you did is fine.
Good luck
Thanks! I will give that a shot and post the result here.
By the way, that is one thing I read about and didn't dare to try yet: formatting system.
From what I read, after formatting /system the tablet will no longer be able to boot into android. In that case, how can I perform adb commands still? Afaik USB debugging has to be on but I will not be able to get into settings (due to lack of boot) and turn it on (and it will be off after reflashing afaik).
When you format system you can't boot in Android, but you can still flash things via fastboot, which uses a different protocol from adb. There was one time I had to format system to fix a cellphone, but if you don't want to try that, no worries , it may turn out without risking
I believe in order to upgrade you need to lock the BL. Once you update you can unlock it again.
Okay, downloaded the image again, this time via XDA. Suprisingly, all files were flashed in less than a min each (sometimes flasing system.img took half an hour or longer). Same result though. Since I forgot to lock the bootloader I flashed everything again after reboot:
Code:
>adb reboot bootloader
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
>fastboot flash boot boot.img
sending 'boot' (8192 KB)... OKAY [ 49.293s]
writing 'boot'... OKAY [ 2.155s]
finished. total time: 51.477s
>fastboot flash system system.img
sending 'system' (262144 KB)... FAILED (remote: (00120003))
finished. total time: 1196.176s
Not sure why it failed here, worked dozens of times. So I simply decided to reflash system.img once more in the same run:
Code:
>fastboot flash system system.img
sending 'system' (262144 KB)... OKAY [ 25.391s]
writing 'system'... OKAY [ 14.744s]
finished. total time: 40.136s
Worked fine apparently, then continued from there as normal:
Code:
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock
All went well this time, no error messages on the latest full reflash or locking bootloader. Then rebooted, and now it is stuck at the Motorola boot screen:
Code:
Failed to boot LNX 0x0004
Starting RSD mode 2
(charger information bla bla here)
Not sure why this happened and what this actually means? It won't boot up and since the bootloader is locked I can't enter recovery or anything. What do I need to do now?
Man... You forgot to flash the kernel (boot.img)!!! And it's probably appearing because of this small mistake!!! Now that you're on RSD Mode 2 you have to fix it another way... I never went to it (only went twice to mode 3), so sorry, I can't help you this time , I will search a little and see what I can do for you.
My mistake on posting, I did flash boot.img before that, corrected my previous posting.
Now I am stranded. And I can't even turn off the device on boot screen.
edit: rescued it, thanks to this posting:
Pushed power + vol up for reboot, waited 5 sec, then held vol down until fastboot appeared (kept pressing the button for about 17 sec until fastboot showed up).
Once there, I unlocked bootloader successfully again to flash all stock files. Xoom booted up bravely afterwards, phew.
Another good news. This time it also applied the 2nd OTA successfully finally! I don't know why it worked this time. Either it's because I (somehow badly) locked the bootloader and unlocked it again OR because I did the flashing this time from my laptop. On the previous attempts I had the Xoom connected via front USB on my desktop computer, maybe that wasn't a good idea after all (flashing on the laptop connection went even faster, too, about 20 sec the most for each file). In the past I used to flash from my laptop as well and never ran into issues either - should have sticked to it maybe.
I guess I won't go for custom ROMs again anytime soon, I've really had it, especially not the one I used to use. Simply not worth the hassle, considering the Xoom wasn't even faster and didn't work with virtual phone providers anymore.

Hi,
so yeah... I got two fatal problems that completely block me from doing anything on my phone.
It started when suddenly my phone's screen turned black, and after a restart it keeps taking me to a screen when it asks for a password to decrypt my data, blocking me from reaching my phone.
So I wanted to recover the phone to fix it, but when i enter fastboot and choose recovery, after a few seconds it shows a picture of the android logo with an exclamation mark on it, and I cannot get into the recovery screen.
Each problem prevents me from fixing the other one, any ideas of how can I save my phone?
Download a custom recovery for crespo. Get your phone into fastmode mode and flash the recovery image.
Code:
fastboot flash recovery recovery-clockwork-5.0.2.0-crespo.img
Then select recovery in fastboot menu.
Encrypt problem is reported in this thread earlier. You may have to do a full wipe and flash a new ROM.
I downloaded the google factory image, but when i run fastboot -w update image-soju-jzo54k.zip (tried two different ones), it fails when trying to write to the system partition (FAILED remote: Write fail).
the other partitions work, but something prevents me from updating the system partition no matter what zip i use, tried many.
any ideas?
Please provide complete log messages shown on PC and phone.
Which phone did you have? soju is for i9020t, and sojua for i9020a.
Try to format data/cache/system via clockworkmod recovery first.

I wasn't able to find the exact model of my phone, but since soju failed flashing and sojua succeeded, i assume it's i9020a.
Anyway, I tried to format data/cache/system via cwm recovery, and after system succeeded, the phone starts "restoring data...", and after a few minutes it stops with the message "Can't mount /data!"
perhaps the reason i he can't mount/restore /data is the reason I'm getting the encryption problem in first place, is there any way around it?

Model is printed on IMEI sticker at back of phone under battery.
Format data/cache/system before flashing sojua image. Skip format system if giving problem.
Code:
fastboot -w update image-sojua-jzo54k.zip
Or try running the batch file as is, and it will update bootloader and radio to latest version as well.
flash-all.bat or flash-all.sh (linux)

ok so soju is the right one for me.
I followed your instructions and now, and it fails writing the system image, the cmd window pretty much looks like that:

OKAY
more OK sendings
sending 'system'
OKAY
writing 'system'
FAILED (remote: Write Fail)
I also tried using the batch file and although the window closes before i can see if any error happened, i get the same "FAILWrite Fail" error in my fastboot screen status, so I assume the same problem occurs.
What about formatting system partition via cwm? Failed too?
no, formatting system partition works. every partition format works, but i still can't update through fastboot.
It might be worth mentioning that I cannot even erase partitions on fastboot (fastboot -w fails, fastboot erase userdata, fastboot erase system etc fails, giving me a FAILED remote: erase fail error)

flashing gapps seems to finish but when i flash CM i'm not sure wether it was installed correctly. it just says
finding update package...
opening update package...
installing update...
and then goes back to the cwm recovery menu, as if it finished.
anyway, i tried rebooting after flashing both and my device gets stuck right after starting, i get the google logo and then the screen just turns black and seems to process forever, and nothing happens afterwards, it's just a black screen.

Interestingly tho, none of the google factory images manages to flash through CWM. they just say update failed without any informative error, while CM and gapps seem to succeed flashing

Google factory images are only flashable via fastboot. But there may be CWMed (cooked) versions available in XDA.
It seems like no matter what rom i flash, it either gets stuck while the phone is loading, or the phone loads and i get this "type password to decrypt" window.
Is there a way to like hard-format my phone, or a way to fix my fastboot flashing problems?
Hi guys,
I had a stock tf700, running ICS (4.1.1) and I followed the really good guide by sdbags on how to unlock/root.
I rooted it with no problems, and used the ASUS unlock tool which seemed to work (it says that my device in unlocked), but now I am stuck in a boot loop
It fully boots up and can stay working for about 30 seconds to a minute and then it just reboots.
I can get access to the bootloader but I have no idea what I'm doing. I haven't installed TWRP yet either.
I'm sceptical of just hitting "wipe data" as I hear I could brick it for good.
Any help would be greatly appreciated....I'm really at a loss!!
I've seen this behavior when the kernel was newer than the bootloader and incompatible - but if you haven't installed anything yet this is unlikely to be the reason for your problems. You can try to enable USB debugging, run "adb pull /proc/last_kmsg" and see if that file contains any interesting information about the reboot.
If you want to wipe data, you can choose RCK from the bootloader menu - if it loads the stock recovery (Android mascot with red triangle), you know that the recovery is good and you should be safe to run "wipe data". I have only seen the stock recovery once and that was almost 2 years ago, but if you press the Power button in the recovery, you may even get a menu from which you can wipe directly from the recovery (use power and volume keys to navigate).

Thanks for the advice. I chose RCK from the bootloader menu but it just boots normally....no Android mascot. Am I doing something wrong there?excuse my complete newbness)
Is there a big risk in running "wipe data"? If I haven't installed any custom ROMs or flashed anything yet, is the risk of a brick slightly reduced?

There's not much one can do wrong here - turn on tablet and hold volume-down until the bootloader menu appears, then hit volume-up to confirm "RCK", that should boot the recovery. If it starts the regular OS instead, something is wrong.

I wouldn't risk it if you can't even get to recovery manually ("wipe data" uses the recovery to wipe - if the recovery doesn't work, it's a hard brick).
Try installing TWRP via fastboot.

Asus TF700T Tablet fix
Try this, it worked for me....and the standard disclaimer: I am not responsible if you misunderstand instructions I give here, if my instructions are wrong, if you forget to charge the battery and the tablet dies halfway through a flash or if your house goes up in flames. YOU DO THIS AT YOUR OWN RISK
Ok, so I think that I may have lost power during an upgrade (can’t think of any other reason for it!!) and ended up soft bricking my Asus TF700T tablet and recovery attempts would just lead to the dead Android with a red triangle with an exclamation point in the middle. My warranty having expired with Asus and any attempt for their assistance proved fruitless.
Well I researched and tried absolutely everything out there – (Hard Reset, installing TWRP, used a tool called Motochopper and flashing a custom ROM, downloaded and renaming .zip files, putting it onto a Micro SDcard is formatted Fat32, Scotts Tf700t Recovery etc.etc. etc.)
I even took it to the local shops and paid to have one of the Mobile Technician pop-up stores take a look at it, then a friendly techno geek………all with the same suggestions most likely a motherboard/hard drive problem.
My Asus TF700T tablet eventually ended up with just the plain white ASUS logo in the middle of the screen, some small print in the top left corner followed by the dreaded words “Unrecoverable Bootloader Error (0x00000000)”.
During all of my research I was led to believe that if you can still get to the recovery screen, where you see the 4 icons, all is not lost so I persisted.
Here is the instructions that I followed that restored my TF700T:
Download and install ADB, Fastboot and the required drivers - Download and run this cool little tool which has it all packed into one: [TOOL] [WINDOWS] ADB, Fastboot and Drivers - 15 seconds ADB Installer v1.1 - xda-developers (don't forget to hit the Thanks button)
NOTE: at the moment Fastboot seems to have issues with Windows 8
This awesome tool installs the ADB and Fastboot.exe to a folder on your C:\ drive (look for a file titled “adb”) as well as the corresponding drivers. This takes about 15 seconds to install following the prompts.
I installed the device drivers - if you have already tried to connect the tablet to your PC and it's recognised as a portable device you should be ok. If not, download the Asus Sync Utility from their support/downloads site and install it.
Download the latest firmware from Asus (Always make sure that you download the correct SKU version -WW, US etc.) and extract the zip twice so you access the blob file (a blob is a collection of binary data stored as a single entity) – copy and paste this blob file into the previously mentioned “adb” folder on your C:\ drive.
Reset the device with a paperclip/needle (about 2 cm down of the SDcard slot)
Power down the tablet and disconnect it from the keyboard dock.
Connect it to your computer via the original USB cable.
Push and hold the Volume Down key (left side of the rocker) and the Power key until you feel the tablet vibrate twice. Let go when you see the tiny script. Read it and it tells you that your tablet is now in Fastboot mode and you will see three or 4 icons (depending on the bootloader version). Select the USB icon to get into the Fastboot mode.
Your PC should acknowledge that a USB device has been connected (an audible indication) Don’t panic if the device does not appear under “My Computer” (as mine did not either – Fastboot will still communicate with it), you can go into Control Panel/Hardware and Sound/ Device Manager and you may see “Fastboot” icon, expand this and the device will be represented again by the “Fastboot” icon. Right click, select “Properties”, Driver tab and then select “Update Driver” and allow it to search automatically and update from the internet. This should then update and change to Asus icons. You now can be certain that you have the current device drivers.
In Windows Explorer navigate to the folder that contains your adb.exe and fastboot.exe
Win 7 press Shift + right click and select "Open command window here".
In the resulting command prompt screen type the following codes (those in bold):
C:\adb\ (or whatever the path to your fastboot folder is..)
fastboot devices (If that command returns a string of numbers and letters, you are good as gold. If it returns: "No devices found", fastboot is not working - yet - and you have to troubleshoot)
Followed by each in turn of the below, selecting Yes as required and allowing each to complete the process:
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
The resulting screen should look something like this below – NOTE, I did make a couple of typos while I was attempting this which returned some multiple choice garble if this happens recheck you input instructions:

fastboot -i 0x0B05 flash system c:\adb\TF700T\blob - depending where you stored your blob, also this was the first time that I saw the loading bar appear on my tablet.
It will now go through the process of reinstalling your Android stock ROM and you should see the something similar to the following:
E:\asus>fastboot -i 0x0B05 flash system e:\asus\blob

I disconnected and rebooted My Asus TF700T and I now have a fully functioning Tablet with a stock ROM.
It has been reported that after completing this you may have some issues getting back get into recovery, hitting RCK and getting the dreaded dead Android (with a red triangle with an exclamation point in the middle). I have not attempted this but have been led to believe that flashing TWRP 2.7.0.1 via Fastboot works.

To whom I am most grateful for the return of my tablet to a working state, I hope this works for you. Good Luck.
I have an HTC One X. I had a good custom rom installed with 4.4.2. Then I made an error. I tried to go back to a saved image of the original rom. It would not load the backup. Then I made the error. I selected Factory Reset on the HBOOT screen. Now I can't get back on the phone except in HBOOT or Fastboot. I can get to HBOOT and TWRP but there is no Restore image.
When I connect the phone to my computer and try to send a file to the phone, I can get a connection with Fastboot but not ADB. To do this I set the Phone to Fastboot and I used fastboot devices on the computer and got a good connection. Now I would like to use fastboot to send an image to the phone. I have rom.zip files but no image files that I know of.
Any suggestions on how I can use fastboot to get my phone back to operational?

I just tried two fastboot commands. This was the result.
fastboot -w
erase successful, but not automatically formatting
can't determine partition type
failed (remote: unknown command)

fastboot update romfile.zip
this took a long time and seemed to be doing something. then got this
archive does not contain 'android-info.txt'
archive does not contain 'android-product.txt'
error: updata has no android-info.txt or android-product.txt
When I reboot, I get the HTC screen but it just sits there for a long time and finally shuts off.
Hi, so I got this phone about a month ago, with stock rom and filled up with bloat and unnessecary crap. So being the fundamentalist I am, I rooted this phone too (5th android phone I've had), and started playing with it.
By default, the bootloader is locked, so I unlocked it using Huawei's website unlock helper and fastboot.
I have no memory card to go with this phone, so I've had to try out the fastboot/adb way of doing this, and so far it's been a hit and miss.
I've been testing with SlimStock KK, and with Ascend G6 Mod, and I'm able to flash the boot and recovery successfully, but when it comes to flashing the system, it fails. Here's the output of that:
Code:
Karls-MBP% fastboot devices

So right now my device is softbricked. Does anyone know how to get around this problem ? Or have another approach to flashing it?
Edit: I might add that I've tried different system images, and different hardware USB ports on my laptop to no avail. I have also tried the flashall, which fails due to no product ID and adb sideload <zip> fails because of a timeout:
Code:

Try putting the .zip file inside your adb and fastboot files and just type the .zip file name when flashing instead of the whole path to the .zip
Hope this will solve your problem.
