ics bootloader

Ics boot loader v 0.03.13-ics

Not unlocked anymore

I don't get to the exclamation point either get boot verified failed if I try to boot or recovery verified failed if I try to enter recovery or flash update.zip both in red at the boot loader info corner (top left)

Will edit whit link but it was official hc (stock) from vache thread if I'm not wrong gen1 was at the end will check on my laptop in about 10 min when I'm home.

Edit:

My bad i selected ics stock Acer_AV041_A100_1.012.00_WW_GEN1 this is what i flashed thinking it was hc

[Acer Iconia Tab A100] mapaz04:
awww man...

I dont like the sound of that... you tried to flash STOCK over the CUSTOM recovery... Sounds like you have parts ICS and parts HC therefore the tablet cannot verify that the partitions "match" with each other...

When you get home, try to plug your tablet to your laptop... See if you get anything to come up (or be recognized)... There may still be a way to "push" something to your tablet...

Post back and let us know...
[Acer Iconia Tab A100] inspiredbyhtc:
I am able to connect fastboot, but its locked and apx mode but dont know how to use nvflash.

Edit: Just to be clear i just discovered i never flashed back to hc i flashed the ics gen1 stock thinking it was hc
[Acer Iconia Tab A100] mapaz04:
ok...

I know that its "locked" but can you still try to "push" anything to it? I know this is probably not going to work but lets start small...

I think if we can get anything pushed we can push the HC image files back onto your device... Download the mmcblk0p1 image I posted earlier (post 28) and see if you can do anything... follow those instructions on that post...

EDIT 1: if this works then we can virtually push all the images to your tablet... it may not like it but it will get you original recovery
[Acer Iconia Tab A100] inspiredbyhtc:
I tried to push (fastboot) it says cant process fastboot operation ( not in this words ) and then it states bootloader locked

I have not tried to push through apx mode as i dont know what to do

fastboot erase recovery

not support the command in lock mode

failed to process comand

Edit: as i have installed ics gen 1 instead of hc i did not use your recovery instead i used the cwm based recovery that came with the instructions to unlock bootloader

2Edit: tried cwm 5 from dev forum result is, same as yours

unknown partition 'recovery.img'

error: cannot determine image filename for 'recovery.img'

Should i rename to the name of the recovery you uploaded?
[Acer Iconia Tab A100] mapaz04:
Sorry for the late reply...

Sorry, just got home from work... took an hr to get here (work 6a-6p)

Alright... I dont think that changing the img file name is going to change anything... try this... open the zip file you used to update and find the recovery.img from there... See if it recognized that one... The one I have is from HC so if you need the ICS one your safest bet is extracting from the update.zip

EDIT 1- As I keep reading your situation... it seems that you "flashed" the recovery WHILE being in recovery so the partition may have been blown away... I dont know if its possible but can you try to see if you can "push" to mmcblk0p1 instead of "recovery"... I dont know if it will work but its a shot we can take... Post back with what it says...

EDIT 2- Also, yes, when you send the command (if you are using my backup) make sure the file is named what you are telling it to be pushed so... if the file is mmcblk0p1.img then the command should read that way, otherwise, yes, rename the file to recovery.img (guess that changes what I stated at the beginning huh? jejeje)

Sorry man... Trying to think what can be done... Thats why I keep updating this post... jejeje :eek:
[Acer Iconia Tab A100] inspiredbyhtc:
The zip i flashed doesn't appear to have a recovery img instead it is a folder named recovery with this inside.

etc/install-recovery.sh

recovery-from-boot.p

will try your image again with rename and report

Tried renaming mmcblk0p1 to recovery, same message (not support in lock mode)

Tried fastboot flash mmcblk0p1 mmcblk0p1.img (before renaming), same

While reading through the forum i found an euu which is supposed to be flashed via apx mode but i dont know anything about that mode, do you think it would be a possible solution?
[Acer Iconia Tab A100] mapaz04:
APX mode...

Yeah, APX mode appears to be our only hope as of now... since adb and fastboot seem to have been taken out of the table :(

I cant give you any information on APX mode though because frankly, this is the first time I have actually even tried to figure anything about it...

Give me a little time, I am reading up on it and will report back as soon as I am comfortable giving directions on it because... I dont want to give you instructions and be stuck without an answer and no way to recover your tablet for sure... :eek:

APX mode for A100... Commited???

I believe we can get the A100 to boot into APX by pressing the RESET button and the POWER button at thesame time while booting the tablet... You are going to need a tooth-pick or paperclip to press reset. However, when you try it, I am unsure what the results would be at this time as there are different ways to get it to APX but they have to be tried...

Also... please realize that APX mode will require many different installations and mods to your android sdk before your pc is ready to run APX...

I have not done this before so... Its up to you. I am willing to continue as this is a learning experience for me but know that this is a deep and involved process...

If we get this working however, it will be a great benefit to all A100 users that brick their devices and for the DEVELOPMENT community.

APX IS DANGEROUS because it basically gives you full control of the device, its like messing with the BIOS on your pc... It can be beneficial just as much as it can be a hazard...

Let me know what you think... either way, I still want to learn more about this mode... But I dont know how long it will take to figure this out completely...
[Acer Iconia Tab A100] inspiredbyhtc:
I have already installed apx drivers, and entered apx mode my tab is detected. I downloaded tegra 2 tool nvflash but im not sure how to use it.

Edit: I was sucessful with this combination for apx

Power down

press and hold reset (paperclip)

press power for 3-5 seconds

let go of power wait 2 seconds

release reset

Sucess black screen on tablet and recognized by pc as apx device

APX...

Downloading drivers now and about to look into the NVFLASH...

This is looking more and more possible... :eek: jejeje :D

UPDATE 1: Alright man.. PM'd you with the files to try... Let me know how you fare out with that... jejeje (Crossing fingers here... jejeje) From what I can tell, should work with that A500 executable...

UPDATE 2: I found through checking the downloaded files that we DO HAVE a bootloader.bin... Find it in the nvflash_config_A100.zip

So open the NVFlash tool and type: nvflash.exe --bl bootloader.bin

This SHOULD get your bootloader back and you can do the update.zip from there... Just another thought... Probably safer to do this first before the other file... Just thinking here... jejeje

And yes, still at this... Trying to figure it out... jejeje

Help request

Anyone out there reading this that can give us some insight of APX :confused:

We have the drivers and what would appear to be a tool that could (POSSIBLY) work for flashing the multiple images to the A100 :eek:...

Any help understanding the full functionality of APX or that can lead us in the right direction would be much appreciated. ;)
[Acer Iconia Tab A100] patrick_spd4u:
Currently I'm stuck at the distorted green Acer logo, can enter Recovery, can enter APX mode.

When trying to use EUU in APX mode, I have to enter the CPU ID, but I have no trace of the CPU ID in my PC.

In Recovery, I'm unable to mount anything, so flashing from /sdcard/ seems to be impossible.

Unlocked bootloader; Taboonay ICS.

Already sent to ACSC (Acer Customer Service Center), but they just asked to replace the mainboard, at the cost of around $300, so I canceled the replacement and just pay the checking fee, around $10.

Is there any way to bypass the CPU ID checking in EUU?

Any recommendation?

Thx alot :)

Messed up my A100

Hi

I messed up my A100 (HC 3.2, GEN2). What I did was..

1. I rooted using su binary and terminal emulator, No issues here, root went fine and i checked with root checker.

2. I tried to unlock my bootloader using the instructions at http://xdaforums.com/showthread.php?t=1557445, No issues here also, I got this message "Bootloader v0.03.06-ICS(UnlockMode): Starting Fastboot USB download protocol".

3. Here I made the mistake, before loading the ICS leak, I flashed CWM 5.5.0.4 For Acer A100 under unlocked fastboot mode. Then I used the update zip from the leak in my micro sd to update using CWM 5.5.0.4 by going in to the recovery mode, by selecting the update zip. I got a message, update successful. but when i rebooted my system, I am struck at white acer logo (which was green before i update with update.zip).

What all i tried are,

1. I tried Hard reset, very fast messages i get, but no use ending in same white acer logo screen.

2. Tried for adb connection, device is trying to be detected as MTP device (strange, it says A500 in device manager), but comes with error installing driver, I tried with A100, A200 and A500 drivers, no luck in detecting in adb.

3. Tried for fastboot, device is detected as Acer fastboot device, but when i tried to flash, command not supported in locked mode (i don't know how to go back to unlock my bootloader).

4. Just checked in APX mode, device is detected in device manager as APX device. I didn't try anything with APX (also, i don't know my cpuid, since i don't have adb connection and i don't have dmsg.txt backup).

One good thing is system is still under warranty (remaining more than 6 months)...

I read this whole thread and tried some of the suggestions like re-installing device drivers, etc., but since the fastboot is now in locked mode, i couldn't do any thing via fastboot, all my attempts to connect via adb is not working (i almost tried all suggestions of mapaz04)

mapaz04 or some body please help me to put back my system to stock or some custom rom.

Thanks

Alright man... Check your PM and let us know if that worked :confused: ... If so, I will try to get a RECOVERY thread going :cool: because MANY MANY people are bricking their tablets... :( jejeje :D
[Acer Iconia Tab A100] patrick_spd4u:
Thank you for the help, now I'm downloading the EUU, will try as soon as possible.

I also managed to get the ACSC to disassemble my A100. In the mainboard, I got several numbers:

2781446201009

MBH6R00001143001DD1601

AP01Q000600B7D001188CX

2778990202318

I hope one of these numbers (especially the bolded ones) is the CPU ID.

How to enter fastboot?
[Acer Iconia Tab A100] patrick_spd4u:
Tried all these codes...still failed.

Need. help.

EDIT:

Before this happens, I tried "Fix Permission" from the recovery menu, then after that I can't mount anything in recovery. Do you know what happens with that?

EDIT2:

Where to get the nvflash_config_A100.zip?

Can you give the link for the NVFlash tool?

NVFLASH

Take a look at this thread seems to work NVFLASH

http://www.grupoandroid.com/topic/4...oceso-al-original-actualizado-cwm-5504-y-mas/
[Acer Iconia Tab A100] jayapalravi:
Yes i saw this, it is basically using the APX flasher GUI based on NVFlash (original details of the GUI is http://forum.tegraowners.com/viewtopic.php?f=30&t=388)

Basically the commands issued by bat file are same as Vache's instructions. The real issue for our device is not knowing the correct cpuid, we need to figure out a way to retrieve the correct cpuid for our device, which should be an easy job, if your device can connect via adb, mine is not connecting in adb. without a correct cpuid, now we cann't flash via apx, unless someone figured out to bypass the encryption of SBK.

fastboot oem unlock

To unlock Fastboot :

(0 : adb reboot-bootloader)

1 : fastboot devices

2 : fastboot oem unlock

3 : Now, look the tablet's screen : select the unlock position (vol up) and validate (vol down)

4 : You're now able to use the "boot" commands with Fastboot ;-)
[Acer Iconia Tab A100] jayapalravi:
I could able to retrieve the ID using USBDeview (http://www.nirsoft.net/utils/usb_devices_view.html), but still no luck with EUU / NVFlash

Thanks, my a100 is not connecting in adb, but manually i could able to start in fastboot mode, but it says locked, when i give "fastboot oem unlock" no response from screen, just i get a Sucees msg in cmd window. (I do remember that lock screen has came, when i initially unlocked my bootloader, before bricking my A100,) for some reason now my fastboot doesn't take oem unlock cmd.

If i give oem lock, then it says, device is already locked. Sameway If i give flash recovery recovery.img cmd it says not possible in locked mode.
[Acer Iconia Tab A100] NoSudo:
Are you trying to unlock the A100 bootloader? If so I think you are running into the same issue we all ran into a few months ago HERE

Currently the way the bootloader is being unlocked is actually to overwrite it(using cat) with an A200 bootloader which CAN be unlocked and will boot the a100. That is what ZeroNull's unlock script is doing when people run it. Once you have the a200 bootloader you can run the fastboot oem unlock and get the icons, follow the on screen directions and note the warning from acer. Once you have unlocked the boot loader, when you start up your tablet you will now see a this message if the unlock was successful. Sorry for the blurry pics I'll redo them with a tripod some time.
[Acer Iconia Tab A100] jayapalravi:
Yes I unlcoked my bootloader earlier using the scripts of ZeroNull's (http://xdaforums.com/showthread.php?t=1557445), I got everything as said in the directions no issue i faced, after that i messed my A100 (details here http://xdaforums.com/showpost.php?p=25230026&postcount=57).

Now my bootloader says "Bootloader v0.03.06-ICS: Starting Fastboot USB download protocol" when i enter in fastboot mode, so i am unable to flash anything (I guess it is locked). Since adb is not working, I can not able to re-run ZeroNull's script. I tried "fastboot oem unlock", no luck, I am not getting the unlock screen with options to unlock. Is there any way we can fix this?
[Acer Iconia Tab A100] peporras:
But he does the recovery?

if so have the original recovery ics or cwm?
[Acer Iconia Tab A100] NoSudo:
What recovery.img files do you have? Or what are you trying to use for an update.zip when you get the fail.

Also another thing you "could" try to test adb would be to download an Ubuntu live cd or dvd image and boot your PC into linux and see if it can mount your device. Linux doesn't need a special driver. Also make sure you grabbed the drivers from acer not from Microsoft.(I'm guessing you did though)

That will only work if you replaced your boot loader with the a200 boot loader. For those who are stuck in fast boot or apx with locked a100 boot loader this does nothing. We either need to find a way to push the a200 boot loader wity a locked fast boot or get nvflash working somehow.

mapaz04,

I am hoping you can give me some insight to what I need to do with my tablet.

I was following ZeroNull Directions for ROOT and Bootloader unlock.

I installed the Acer ICS update from ACER OTA.

I then followed ZeroNull ICS Root method. http://xdaforums.com/showthread.php?t=1531646

I then followed ZeroNull Unlock Bootloader method. http://xdaforums.com/showthread.php?t=1557445 and got stuck at step 4. I never saw a place to enter the command 'sudo fastboot reboot-bootloader' however it looked as if I got the unlock to work but never the USB download or transfer.

So I tried to go into recovery by pressing Vol up and Power button on. It seemed to flash something off my sdcard. I realized I had a HC update.zip on sdcard which changed Gen1 to Gen2.

I am now stuck at the Acer green logo with the words 'Bootloader Version 0.03.06-I (Unlock Mode).

I can't do anything. I tried to press vol up with power and it tries load something from the sdcard. It says something about update.zip from sdcard really quickly then goes to an android with a blue atom spinning in the belly trying to load up something.

It then shows a dead android. If I reboot it is stuck at the Green acer logo with the Bootloader Version0.03.06-ICS (Unlock Mode).

I press the home button with the dead android with red exclamation mark.

I get e:/dev/block.mmcblk1 does not exist about 10 times

FInding update package

e:failed to mount .mnt/sdcard

e: can't mount /mnt/sdcard/update.zip

Installation aborted.

I can't seem to get my PC to recognize the Tab. Any suggestions? I tried to rename flexreaper rom to update.zip on sdcard but doesn't work.

Do I need to fix the e:/dev/block/mmcblk1 of ICS install?

Thanks.
[Acer Iconia Tab A100] ptesmoke:
If you are unlocked boot into fastboot...bootup for recovery "vol - and power" but also flick rotation lock back and forth.

once in fastboot open cmd on your pc and flash cwm according to inst in my cwm thread. boot into recovery and flash cm9 or flexreaper ics.

[Acer Iconia Tab A100] yazyazoo:
I finished off with these steps in ptesmoke thread.

http://xdaforums.com/showthread.php?t=1601663

I download CWM recovery .img in that thread. Put it in same folder C:\android-sdk-windows\platform-tools

Put tab into Safeboot with the method ptesmoke just told me above. However my pc wouldn't recognized the tab with any of the adb commands or adb devices command didn't show anything.

From that I opened a CMD window with admin rights and went to the platform-tools directory with the CWM recovery .img.

I decide to just try fastboot command: fastboot flash recovery recovery.img

I heard tab and saw my pc send recovery to my tab.

then reboot tab with command: fastboot reboot

Then I got civato ICS rom download from the A100 Dev section. Renamed the rom to update.zip and got my sdcard and used my pc to place this file on the root of sdcard.

Put this sdcard into the A100 and pressed left vol button(landscape) and power and it booted into CWM.

I then chose to update from zip from internal sdcard zip file. Use vol buttons to change and power button to select the options in cwm.

Saw it flashing my tab and was good to go!!!!

Sooo happy!!!!!

Hope it works for you.

Which file/partition is responsible for mounting process in A100? Is it bootloader? Or flexrom? Or boot.img?
