Solution: Unlocked bootloader Installation

ERROR: Can´t installl hacked ICS Bootloader
I tried installing Hacked ICS Bootloader in Order to get Moscow Desire´s "Alexandra V a501 ICS 4.0.3 ver 1.4 Final" running on my a501.
The following ways of flashing could get the hacked bootloader on my a501:
"Afterota for A600/G100W" (http://forum.xda-developers.com/show....php?t=1675939),
"blackthund3r´s ATX flash tool A500APXFlash.exe" (see "Automated flashing tools" at http://forum.xda-developers.com/showthread.php?t=1622425")
"Manual flashing via nvflash" (see Manual flashing at http://forum.xda-developers.com/show....php?t=1622425)
Trying to flash with this tools always brought me to a Command Promt saying:
Nvflash started
[resume mode]
APX flash tool hang when it tired to Format Partition 4 etc.
and then doing nothing even if i let it stay for hours. No Information or Error so long.
When i tried flashing manualy (see link above)i finaly saw an error:
failed executing command 25 NvError 0x120002
command failure: sync failed (bad data)
bootloader status: partition table is invalid, missing required information
e: 14) message: nverror:0x4 (0x4) flags: 0
So it seemed however that the partition table on my a501 got messed up. Asking google for "failed executing command 25 NvError 0x120002" brought me to an answer "lcd047" posted on tegraowners (http://forum.tegraowners.com/viewtop...p=15285#p15331)
He desicrbes same problem with messed up partition table an restoring it with timmyDean´s root-3.2.1-V4.7z (http://forum.xda-developers.com/show...&postcount=1):

without rebooting, I flashed the v7 bootloader and recovery as per the bootloader thread; since the partition table was restored at the previous step, the operation now succeeded;
I rebooted the tablet in recovery, and proceeded to wipe the data and flash a ROM the usual way.
And that worked for me. After flashing, my a501 did a automated reboot, i quickly killed the reboot by holding the Power Button (guessing killing the reboot is not realy necessary because the booting shouldn´t mess up the partition table again) and then brought the devive back to APX Mode (Holding Reset and Power for 3-4 sec. then releasing Power and after 1 second relesaing Reset).
Then i flashed the hacked bootloader via blackthund3rs APX flash tool (see link above).
Then i installed Alexandra V as Moscow Desire descirbes (see "To Install" at http://forum.xda-developers.com/show....php?t=1635577)
It took my 2 days of trial and error, but finaly give me a nice working Alexandra ROM on my a501!
Hope this helps people having the same issues.

Note from MD. You guys take note of this. Sometimes, when you get corrupted partition tables, you may have to go back to an HC stock bootloader to get them fixed. Of course there are other methods, but require some indepth knowledge, and this method most people can do easily.

Help
i'm use a501 3.2.1 stock HC and still unroot.
Now i wanna use alexV ROM, so i have flash ICS BL use blackthunder's flash tools and it's success, with V8a50pub recovery.
but my problem is:
1. still able to boot my stock HC ROM,
2. can't boot into recovery mode, it will display green robot with exclamation in its body
3. can i get guide to flash cwm recovery? i want use CWM-install-A500PubRecovery_v0.2.zip but its extension is .img and i dont know how to use it
sory if i asked noob question
thanks

Go on youtube and just search up how to root acer a500 , its the first video, steps are simple but i'm not too sure you can use pub recovery on honeycomb, after that use one of the flashing tools to install the hacked bootloader ( i prefer the apx flashtool, its fool proof pretty much with the sbk generator built in ) and download the v8 bootloader with your recovery choice and install it, there's even a guide on youtube on how to do it, hope it helps

So, While this did not actually work in my case, it led me to do a search on "TegraOwners" for "Partition Table damaged" where I found "BadSector" which totally fixed my problem. So, A Hearty thanks to you Moscow Desire, as well as to BlackThund3r, for without his direction, I never would found your post either.
That being said, a big thanks to all the Dev's on this site, for without their hard work, there would be no reason for any of the fine information available on this site!

Hey i have a similar problem and i cant figure it out ..heres what i get:

If these 2 tools "don't work" there are only 2 possibilities
a) you're not doing things correctly
b) your tab has a faulty memory chip and needs a replacement motherboard

Fixed!!! Thanks to Moscow Desire & BlackThund3r, for the leads to the final solution, and obviously bsg19071979 for the actual solution. The partition table was invalid. I ended up using "BadSector" (Had to follow multiple threads on XDA then over to TegraOwners, Then finally back here, to this post "http://forum.xda-developers.com/showthread.php?t=1691729&page=3"

So can someone tell me what i can do to fix this thing?
I was running Stock ICS 4.03, havn't cared much for it, & wanted to go back to Stock HC 3.2, so tried flashing "Acer_A500_7.006.03_COM_GEN1" from A500 Dev forum. (followed directions, but it would just give the android, on his back, with red exclamation point, then re-boot back into 4.03.)
Read somewhere that I should try using the update.zip file from within the archive directly (rather than renaming "SD_Acer_A500_7.006.03_COM_GEN1.zip" to "update.zip"
Tried that, seemed to work fine, then screen went blank when update was nearly finished, and now can only boot tablet in APX mode. (Lost recovery??)
I have tried replacing lost recovery using APX_v0.4A-flashTool-500Manager1.0.2, The manager says it detects the tablet in APX Mode, but when I try logs, it either just stalls at "Waiting for tablet" or says "No device connected"
Tried to install "EUUs_SBK_Acer_A500_1.016.05_COM_GEN1" (HC 3.01) and it will actually put the tablet into download mode, but will go no further. (At least I can see that the tablet's screen is capable of doing something, as opposed to just being black!)
Any Idea's what will get this tablet going again?
EDIT: Using APXFlash tool, for some reason, on 2 different computers, the text on the buttons doesn't show up, so, The only button I could see was "Dump My BCT", when I clicked it, I would get the BCT file not found message.
I found a tutorial (that showed where all the buttons were & wgat they say, & just used the default BCT. Still cannot get past the "Flashing Bootloader (EBT) stage two - uploading image..." message... nothing is happening, just stalled. Still need some direction...
Thanks

In short, being on stock ICS you also had the ICS bootloader and cannot just flash back to any earlier version. Most likely you now have several pieces of different ROMs embedded on your tab. Take a look at TimmyDean's excellent tutorial which will take you back to v3.2.1 and allow OTA updating: http://forum.xda-developers.com/showthread.php?t=1516012
Goodluck!

So, this is pretty much the same thing I was trying with the EUU file from Acer, and produces the same result. It goes as far as saying "Upgrade is under way. It may take more than 10 minutes." Then it appears to start flashing, (The progress bar starts to move) then errors out with the message "We are sorry! The upgrade process failed. Please follow the instructions for recovery" ( So, what exactly are the instructions for recovery?)
A note maybe worth mentioning, this Tab is stuck in APX mode, so when I get the prompt to enable USB Debugging, I am not aware of a way to enable it, also understood we didn't need that as we are using APX mode?
As well, I know I have the right CPUID, as I looked it up before starting the flashing process, and have just now verified it by liiking with USBDeview.
I am using 0380620044400497.
So, after conneccting the tablet, but before running the flash update, I opened a command window, & ran ADB devices. Got the following output:
adb server is out of date. killing...
* daemon started successfully *
List of devices attached
Notice there are no attached devices, yet As I mentioned earlier, I do not know of any way to turn on USB de-bugging, and I am in APX mode, so I shouldn't expect to see a device through ADB, Correct?
So, is this going to work at all trying to load a bootloader/recovery if I cannot turn on USB de-bugging?
Sorry, again, Any thoughts?

[Q] Need Help Recovering - Driving Me Crazy

I have flashed a lot of stuff, but this Iconia is driving me CRAZY.
For starters, the tablet will only boot into APX mode when you turn it on. Blank screen, but the power light is white/blue.
I DO have the SBK, which I grabbed through Ubuntu.
I try using the blackthund3r utility. It detects it in APX mode fine and pops it into the bootloader, but after that it gets stuck. This is at "Flashing Bootloader (EBT) stage two - uploading image..." The command prompt just displays Nvflash started [resume mode].
When I try running v8.bat manually from the command prompt, I usually get a lot of failed command errors which come at different points at times.
The other day I miraculously used the blackthund3r utility and handpicked some bootloader and system files and got it to boot back into Android, but when it tried updating OTA it got stuck on reboot saying the "blob update failed." Now I am back to the start of this post.
I've updated the drivers a few times and also installed the Android SDK. Everything is up to date.
If anyone has any idea what might be holding me up I could use the help. My girlfriend is mad now that I have re-destroyed her tablet after bringing it back to life and I need to get it back to her.

Have you tried using Ubuntu to run the nvflash commands, some have had luck with it where windows won't....
Srbeens guide (its stickied in the general forum) to recovering sbk via Ubuntu also has a few steps in running the nvflash commands directly from Timmy deans v4 EUU which is used to repair partitions, there might be something there u can use...

k, hopefully its just your partitions messed up and not the dreaded hardware failure... you got couple options left and both of these will work from apx mode
timydeans v4 an EUU based tool which will give you a pre-rooted stock HC3.2 and cwm installed too - it will wipe everything

The other way is by using the "babsector.rar" from the russian forums -
you can download it http://forum.xda-developers.com/showthread.php?t=2049778, theres a couple of good links in post 13 of that same thread on how to use it correctly
You don't say which rom was on the tab previously - so once the partitions are repaired and you've run the unlocked bootloader flash you'll need to immediately boot to recovery and flash an ics/jb rom ...do not try booting into android until you have done this....else you'll need to do everything all over again!!!

Very helpful threads. Exactly the problems I was facing. Using the babsector a501a commands, I am getting a "create failed: (bad data)" and "bootloader status: fatal failure to read/write to mass storage" errors right after it creates the partitions. I am guessing that it is probably faulty memory then and it just can't write to it no matter if I am doing it correctly or not. Thanks for all your help.

Cannot install custom ROMS or unlock bootloader [SOLVED]

I have been trying with every guide and every video I've found to install a custom ROM (CM10 FLEX). Youtube videos generally tend to leave out the fact that you need to unlock the bootloader first. So I go to bootloader guides and follow those and nothing seems to work.
I have attempted to use Blackthunder's Manager and Flasher tools to get it working and something always hangs or gets stuck. With Blackthunder's app it was stuck at the "uploading image" phase. Same goes for AfterOTA.
I'm sorry I'm being vague, but it'll be hard for me to type out every scenario and every program I've tried since I literally just spent 3 evenings and about 6 hours trying with this. My google results are all red because I've looked at every thread already and every guide.
So I'd like some fresh advice and opinions. Where should I start? It's a rooted A500 running ICS (from the standadrd acer update) and is pretty much stock

If a500 manager hangs u will need to flash manually using nvflash.
Civato has a guide stickied in dev forum.
Basically download the v8 bootloader.zip file, extact it, put yr tab in apx mode and run the .bat file.
You will have the option to flash a custom recovery along with the v8. After the flash boot directly to cwm and flash yr rom! Done...

And you're running the bat file from apx mode and yr tab is displaying
Acer iconia downloadmode??
The flash should takeno longer than 5mins total.
If its stalling here check apx device is showing in device manager or under safely remove
Hardware icon in the system tray. Do u have adb/fastboot installed. They come with
the android sdk or u can d/l them from the rootguide in my sig.
Do u see the system info window at all does it stall after/before this:

And you're running the bat file from apx mode and yr tab is displaying
Acer iconia downloadmode??
The flash should takeno longer than 5mins total.
If its stalling here check apx device is showing in device manager or under safely remove
Hardware icon in the system tray. Do u have adb/fastboot installed. They come with
the android sdk or u can d/l them from the rootguide in my sig.
Do u see the system info window at all does it stall after/before this:

It was running in APX mode and the A500 was showing that it was in APX mode. How would you recommend I get into APX mode? I ask because I've seen various guides that have different ways. The only way I was able to get into APX mode was using Blackthunder's flashing tool and when the A500 was in APX mode I used the other tool (while abandoning blackthunder's tool) to try and flash it.

The device manager wasn't showing an APX device and neither was the "safely remove hardware" tool, but the tablet was still showing it was in APX mode.
I just now tried the "AfterOTA" tool and the tablet says it's in APX mode, but the tool has been stuck on "3/5 Flashing kernel" for about 5 minutes now.
While it was in APX mode again I tried starting the Blackthunder tool. After it failed to start the first process, I closed the command prompt window and it appeard to continue through the process. It got to the "Flashing Bootloader (EBT) stage one - formatting partition..." stage, and in the command prompt it said, "Formatting partition 4, please wait..." but after about 10 minutes....nothing.
Upon a reboot nothing has changed. My tablet isn't bricked and the SD card contents are fine. While it said it was formatting the partition and throughout this process I didn't see anything about "APX" devices in the "safely remove hardware" tool or in the device manager. Though I think I do require a reboot, as now my flash drives arent even showing up in the "remove hardware" tool.
I tried the blackthunder tool again, and I still don't see an APX device in "Device manager". Before it enters APX mode I see an ADB device. But when the blackthunder app says it's in APX mode (Acer screen is completely black) I don't see an APX device in device manager.
However, when I proceed to the next step using blackthunder's tool, I get a green "Acer" logo and in the upper left corner it says, "acer iconia apx mode." And this is where it gets stuck. The black command prompt says, "NVflash started [resume mode]" and the blackthunder program says, "flashing bootloader (EBT)- stage two - uploading image.
I do have the entire android SDK (latest as of 14 Sep 2013.) So I do have adb/fastboot.

K m8 - something is defo amiss -download babsector.rar in the root guide. This will reset yr partitions and flash bootloader and recovery. It will also detect and display any errors.
When u r having probs like yrs it is best to put ye tab inapx mode via the button combo and flash manually, pls post the output of commands....but I have to say its sounding suspiciously like yr memory chip is faulty...we will know for sure once you've run babsector!

I downloaded babsector, but it looks just like nvflash. Are they the same tool?
Also, I have never once gotten the tablet into APX mode using the manual method (power + reset button, right?). Every time I hold the power and reset button, wait for it to reboot (3 seconds) and release the buttons (power button first) it just powers up like normal.
-edit-
Also, I've been searching for a while now and I can't seem to find a guide showing how to use babsector. Do you have a link handy? What guides I did find said to run "A501 A.bat" first, and when I do that it asks for my SBK and then says "nvflash started. No usb devices found. Press any key to continue..."

My question will sound odd, but from what I've read above, it looks like your computer doesn't see your tab in APX mode:

I remember mine seeing it when I was under APX mode, are you sure you have the right drivers installed ? I would not proceed any further until the comp sees the tab under APX.

yes, the proper drivers are installed. I believe the issue isn't related to the tablet, but something in windows (a service, maybe) that I disabled.
I got the tablet into APX mode using blackthund3rs A500 manager, ran babsector, and here's the output:

-edit-
upon rebooting the tablet it came up with a skrilax bootloader. I entered recovery mode since the primary and secondary kernels failed. I was able to follow the usual guides and install the ROM. However, now it wont boot. It just gets stuck at the bootloader since there's no valid kernel image. What now?
-edit-
Looks like it was messed up partitions. The fix was to put the tablet into APX mode, run babsector, and then proceed as normal.
I tried installing the ROM again and it worked fine this time. It's loading up now. But it's stuck on the "android" screen with the flashing animated "android" text. It's been doing this for about 5+ minutes now. How should I continue?
-edit-
I tried another ROM since I am able to get to the recovery console. I tried CM-10 unofficial (before it was CM-10 FLEX). I get the animated cyanogenmod loading screen and then nothing. It just sits here loading.

Well from what I remember, when I encountered that kind of problem on my devices, I made a total wipe and reprocessed the installation.
Just to be sure I would under fastboot do:
fastboot erase userdata
fastboot reboot
then under recovery, wipe factory and format flexrom. then re install.
Hope this helps.

I did do total wipes before each install. I wiped the cache, did factory resets, and wiped the delvik cache.
When I try "fastboot erase userdata" it just says "waiting for device". I am at the CWM Recovery v5.5.0 main menu. Which mode should the tablet be in?

First you need to be in fastboot mode, instead of going into CWM by pressing "volume down" while it's booting, press "volume up" and choose fastboot mode.
Also if you have an error message while doing that, maybe you'd like to take a look here: http://forum.xda-developers.com/showthread.php?t=1431907

That did it. I didn't know about the volume up option. I did the fastboot stuff, cleared the cache and did a factory wipe, re-installed CM-10 unofficial, and I just rebooted 8 minutes ago (I'm timing it.) still nothing. Just the cyanogenmod logo with the animated swirl going around in circles.

there are 2 bat files with babsector.
after running the first one, you reboot to recovery and do a full wipe.
there is an option to "enable data/media" do that and it will fully wipe your device. I think its in the mounts and storage menu.
Once you do that flash your rom.
On reboot you must see "skrilqx_cz unlocked bootloader" displayed on-screen
If you don't have this then fastboot will not be available.
Rerun either babsector or the v8/v9.
To enter apx mode manually - You must be sure you are holding in the reset button...otherwise your tab will boot normally as you have found - using a paper clip ( or anything "non-pointy ended ) you will feel the button push in.
(Try holding the tab on its edge on your lap with the power button on your left and the reset button on top)
Press in and hold the reset button
Then press and hold the power button for about 3 seconds.
Then after a second or so release the reset button.
The time part isnt critical, its the delay between releasing the buttons thats important AND having the reset button puched in.
Once skrilax_cz is installed, you can enter "fastboot" by pressing power/vol up
Choose fastboot from the menu ( there may even be an option on the menu to wipe)
Connect your tab to yr pc and open a command prompt on the fastboot folder.
Enter your erase commands and then "fastboot reboot".
Oh and also - u said you were running stock ICS - if you lose your custom recovery and end up with the dead android screen, you will have to delete the .boot.p file as stated in the guides.

I don't know if I'll be able to help you much more than that as I never faced that problem (well that one persisting never happened to me on the Iconia, it did on the SGS i9100 but it was because of a faulty kernel)
You could try to flash first a rom like the one from civato, RE-FLEXxx-ShellSHOCK, see how it goes, also are you formating flexrom ? (from advanced in CWM), it helped sometimes.
Btw I'm using CWM public recovery v0.2 (based on CWM 5.5.0.4, there's a thread in dev section), along with bootloader V8. Never had a problem using any rom with this one.
--edit
My bad, I said flexrom format was in advanced, it's in mount/storage menu.

I've only run the first batch file, batch file A.
I finally got it into APX mode, ran batch file A, and reset everything. However, there is no "enable data/media" option under the mounts and storage menu. I have:
mount /system
mount /data
mount /cache
mount /flexrom
mount /sdcard
and then for each mount option I have a format (format /system, format /data, etc...)
If I do have to delete the boot.p file, how is that done?

This post was made 30 mintues ago and the cyanogenmod logo is still on the screen swirling after the new flash and reboot.

45 +/- minutes now. I'm shutting it off again.

I repeated the steps and tried a different ROM, CM 10 flex again. Still no joy. Been sitting at the animated boot screen for a few minutes now...and coffee is already made since the last ROM reboot.

ok here we go...grab yr beverage of choice
boot.p file is a file on stock roms that overwrites your newly flashed custom recovery..if you still have cwm you dont need to worry bout it!
The reboot shouldnt take that long - maybe 10mins at most.
You will need to go in and wipe EVERYTHING twice! Yes twice!!
this means System, flexrom, Data and cache. After erasing/formatting System you will not have an OS so be sure to flash a rom before rebooting.
Either fastboot erase or cwm format - (choice is yours but I find fastboot just as easy but its unforgiving..you do not want to muck up in here!!!)
You may want to update to the latest cwm - heres a recovery.img http://forum.xda-developers.com/attachment.php?attachmentid=2238701&d=1378452510
Put it in the folder where you have fastboot. Then boot to fastboot andenter
fastboot flash recovery cwm_1.7.3_recovery.img
EDIT: did u run the 2nd bat file from babsector??

[Q] Stuck in APX mode. No CPU ID. Help.

So I did have a file will all the the information CPUID. SBK. Everything. But now I can not find it (I have apparently deleted it at some point).
I tried flashing a new rom and it bricked my tablet. I also can't boot into recovery because the volume buttons are broken. So all I've got is APX mode. Is there anyway to get out of this with out a CPUID? OR is there a way I am able to find my CPUID when I am not able to boot (and start the ADB service). I have tried everything I can think of and have searched the internet with no results.
I have an acer A500

See cpuid guide in my Sig there are 8 methods to retrieve it. Any nandroid backup stores in a txt file in the backup folder.
Not having volume button is gonna add to yr probs if apxflash cannot boot u to apx mode and get u yr cpuid.
If u have the unlocked boot loader you can hook up to yr pc and use fastboot to get u into recovery. Once yr tab is running again install a reboot app or flash a cm Rom which has reboot options in the shutdown menu.

Hi guys
This trouble looks like mine ....
I'm going to explain my trouble too (sorry for my English, I'm French ... )
My A500 tablet was stopped in the acer logo page, at begining of the tablet boot.
I tried Volume- and Power, I had an android on the floor with a red triangle.
I found the CPUID with the ubuntu method.

I restarted my tablet and ..... here's the real trouble !!! My tablet didn't restart, and worst the trouble was very very worst ... no acer logo, no vibes, nothing, nothing, only black screen and power button ON.
Like if I was in APX mode. My tablet is still reconized in windows as Acer Picasse USB device ....
How can I fix my tablet ?

Hi Dibb,
Of course, if I hold the power button, my tab switches off.
But, now I have again the trouble.
As I told in my last post, I succeeded to install the EUU software and have the HC 3.0.1.
But I did the official updates by ICONIA TAB Update Enhancement from the 1.016.05-COM-GEN1 to the 7.014.01-COM-GEN1 (HC 3.2.1) without troubles. At this step no more official update.
I updated the ICONIA TAB Update Enhancement, and it found me a new one : 041.203.01-COM-GEN1 (I thought it was the ICS one), so I did it.
And my troubles came back !!!
My tab stucks on the ACER logo page. So I tried to update the bootloader. Since this moment I can't anymore launch the nvflash.exe. Each time, with any bootloader I have some error logs after creating partitions :
Either : formatting partition 2 bct please wait.. failed
or : bootloader status fatal failure to read / write to mass storage (code 9)
How can I do to downgrade to HC and install it again ?
Any precision : I tried APX Flash and AfterOTA without success ....
Thx a lot

The Update enhancement tab IS ONLY FOR upgrading FROM HC to ICS. THe bootloaders are very different between HC and ICS, so, once you are on ICS you sorta have to stay there. you cannot flash an HC rom from ICS, you need to do a downgrade.
Either, do a full downgrade back to 1.016.05 it should give you an update straight away to 4.xxx.xx, if not just flash the v8 unlocked bootloader from there, unless you want Acer Stock ICS
AfterOTA won't work unless you have completed the full OTA update process.
ApxFlash tool is the only tool that repairs bct error, its not very good at it once you have received that error as I posted earlier -
