ok first thing if you havent tried anything major to fix it DONT

Ive seen far too many fellow noob-ites get into far more serious trouble by

taking the "shotgun approach" -flashing this that and the other trying to "fix" things and really borking their tabs:( Its much easier to fix things by asking for help before the 'bork' as you have:)

I;ve read something about this error - maybe in the guide - was referred to as the "dreaded 0x4 error" ive just done a quick search but can find nothing on it...

I am definitely not a programmer or pretend to understand such things:) so i try and fix things starting from the beginning and working my way slowly and carefully thru each step, SO

what rom are u currently running and what is it you are trying to flash to??

Firstly I'd be checking the files you've d/l and you are using the correct bootloader zip, HC for HC booties and ICS for ICS booties -
[Acer Iconia A500] citsong:
Haven't tried anything major to fix it. Was following Civatos guide so I flashed the light ics zip he had as I was pretty certain my sbk was ok when I did his test and didn't get the error he referred to in his OP. Was originally on flexreaper r12 before I started trying to get the unlocked BL as he stated he was probably going to only work off that BL. I've re-downloaded all the files and still get the same errors. Even tried doing everything on my laptop to see if somehow my pc was causing a problem but got the same errors there.
[Acer Iconia A500] dibb_nz:
ok great u got ics rom with the hc bootie....

now, u say you cannot get into apx mode maually, r u sure??? it really is the best way of doing things, u can feel a tiny click in the reset hole once u have it held in then its just a matter of holding the power button until the WHITE POWER LED comes on THEN count the 3 seconds and let it go....another sec and let the reset pin go....the only way you know its in APX is that white power LED and Black Screen
[Acer Iconia A500] citsong:
OK so getting into apx mode manually vs using the apx flash tool can make a difference? When I flashed the ics zip didn't that give me ics bootloader?
[Acer Iconia A500] dibb_nz:
the tool is beta.....i've used it about 5-6 times....if u read my post earlier yesterday

i listed some of the issues i had----blackthund3r replied and said that its in beta and therefore some things may not work as they should, go have a read.....

the problem i found with the tool is that will go thru the whole process and say its done but nothing has changed on the tab

another one - it does not detect the fast boot drivers properly and will get all the way to the end and then fail - you dont know WHERE it failed just that it did

or it doesnt detect apx drivers and gets stuck at the black screen

if an error happens like stuck at "nvflash resume" what do u do???? this happens with civs flash as well

these methods and tools for flashing bootloaders is all new - with HC3.2 we never got root or cwm unless we flashed a pre rooted pre installed or custom rom. it wasnt like HC3.0-3.1 where we could use an app to root and install custom recoverys...ICS is a whole different ball game - becos the OS is new we all have to start at the beginning - unlocking the bootie is a complex process AT THE MOMENT with the way civ, BT and all the other devs are going we may have a one-click unlock, root, installer in the near future...but for now we have to go about it the long way.... and theres a lot more risk as we are reading from the posts in the guide and the please help i'm bricked threads.....

getting into apx mode manually just helps with troubleshooting issues.....

it helps stop u getting so frustrated that you throw what caution u did have out the window and nek minnit......shot gun approach....blasting away at anything with everything you can find, in the hope that 'something works'

You may want to try the easier way but if things go bad you'll wish you had done it the other way.....

mosccow and me were helping a dude last nite,,,,we tried everything in the end

but with no success....the guy didnt have his cpuid,,, hed tried to 'fix' it by flashing an update.zip and ended up with "Boot Verified Failed" error. This ended up being unrecoverable but only because he never had a copy of his CPUID.

Hes sending it back to acer to fix.

I'm sorry to sound so negative, plenty of folk have used the tools with no issues at all, so you cant really blame the tool....its the way its being used that isnt correct and if you[re wanting a quick fix then i'm sorry....i cant do quick:o

your issue is that theres been a stuff up with your bootloader, either the one you chose wasnt correct for some reason or another i dont know, u have said you have re downloaded everything - so what have u d/l exactly????
[Acer Iconia A500] citsong:
I re-downloaded the Acer drivers uninstalled and reinstalled. I downloaded the ics flash zip that has the go.bat file. I haven't managed the manual way of getting into apx so that's gonna be my goal after work tonight and see if that helps. I know the light ics doesn't have recovery but is it supposed to have root? It has su installed but denies everything. I understand about ics changing things. Had to get soff on my raider to flash a new hboot so I could run an att ruin to get an ifs hboot. I'm not really wanting to try anything desperate as the tab works and I have the root goodies on my phone. But thanks alot for helping me out. This tab was my 1st Android toy but my raider has gotten more attention lately and man are they different for everything.
[Acer Iconia A500] dibb_nz:
OK m8 all good, I'm not sure if u r using the right pckg with the right tool. There is no bat file required for BT tool???? Never mind I,ve posted below what u gonna need to use his tools, so go to the thread and get the packages and the a500 manager and we'll go thru it later, happy day

-
[Acer Iconia A500] citsong:
I have those files also, but since bt's flash tool was getting hung up on loading image, I was just using the manager to get into apx mode then I'd use the go.bat file in the zip from civatos guide. Using that I was at least able to kinda see what it was doing.
[Acer Iconia A500] smallblock:
trouble finding cpu id

At the moment i'm still running the KJY2010 Icilicious rom and most probably a HC bootloader. I'm trying to upgrade to the ICS bootloader.

I've tried almost everything to get the right cpu id from my A500, without succes.

I did make nandroid backups but lost them due to data corruption on my sdcard :(

On the first pc i wasn't even able to install the Acer usb drivers. On a second it worked just fine.

With usbdeview i can't get a serialno; there are 3 devices listed with the correct vendor- and product id but only the usb composite device lists a serialno with 11 digits, the other two have empty fields.

I do have an entry from a Iconia a501 Tab from last year when i had a a501 rom running. This serial does have the correct 15 digits. When i try this number with the added 0 in front and use the generated SBK, i get the dreaded

rcm version 0X4

Command send failed (usb write failed)

ADB also returns the wrong 11 digit serialno

Please advice
[Acer Iconia A500] dibb_nz:
if you are on the HC b/l then there is no reason why "adb devices" shouldnt work for you - have you tried that yet - the "adb.zip" is in the first post, try that:)

EDIT: Sorry missed the last line if your post....

If adb gives u an 11 digit number then chances are you're on the ICS Bootloader

grab terminal emulator from the market and install

REBOOT YR TAB

then open Term. Em and type:

dmesg | grep androidboot.serialno

also download "A500 Bootmanager by Blackthund3r"

EDIT: Get it here from Civ's Guide at the bottom of the first post

it has a "checker" to detect your CPUID and Bootloader Versions

hook yr tab up to yr pc and run the "checker" what does it say???
[Acer Iconia A500] smallblock:
Well here are the results:

dmesg | grep androidboot.serialno gives no output at all

A500 Bootmanager by Blackthund3r:

Busybox is installed

The bottom line says "A500 Detected in normal mode, Debugging Enabled" (should be ok then)

Get serial number: no result

Get bootloader version: no result

Even tried Dump dmesg to desktop, which it does ok but in the file there is no androidboot.serialno to be found at all

Not a very promising result ;)

PS: If the bootup of ICS shows a garbled screen for a few secs, isn't that an indication i have a modified HC bootloader?

Thanks for your help
[Acer Iconia A500] dibb_nz:
Well, you may think its not very promising...but it does tell us alot.....

just trying to verify your bootloader version mainly, we can get into all sorts of issues trying to fix things if we dont get that nailed down.....Assume you have ARI (acer recovery installer) please run that for b/l version and recovery version - all the info we can get the better

But its looking like you are on the HC one....doesnt explain why we're not getting any type of result for your cpuid...it maybe drivers so if you have the acer ones there. then it might pay to run the setup again, then we can rule them out.... AFTER you've rebooted everything and plugged the usb cable into a different port, try running boot manager again, it should, at the very least, pick up yr b/l
[Acer Iconia A500] smallblock:
The bootloader version is 3.01

Recovery version: CWM rev 1.3.4 by Thor2002ro

When i run the blackthund3r A500 manager, "reboot" and enter "APX Mode" does work. So communication with the tablet seems ok.
[Acer Iconia A500] citsong:
Did you try this in the terminal?

dmesg>/mnt/external_sd/dmesg.txt

It spits out alot of stuff in the txt but the serial no is in there. That worked for me when dmesg | grep androidboot.serialno didn't
[Acer Iconia A500] dibb_nz:
ok options are getting slim....usbdeview....would u have plugged your tab into any other pc or laptop BEFORE switching over to any ICS based rom OR ........a nandroid stashed......... "anywhere"!!!!!

Your only option is to revert back to HC to get yr CPUID and without it you will need an update.zip to do it and i dont know of anyone who has done it this way -the EUU based rollbacks are the most successful but require your CPUID so that rules them out - I'll need to think about this for a bit!!!!........ coffee, where's the dam coffee!!!!!:)
[Acer Iconia A500] dibb_nz:
it did???? thats weird, it never worked for me not on the hc bootie anyway....but thanks for that m8, i'll file it away for future ref!!!:):)

now m8 what rom were u on when u struck probs unlocking....was it F'reaper???

still mulling over yr issue and how rolling back fixed it, not so much the rolling back but running the same files in apx didnt work b4 but worked after??????

you had no probs with yr cpuid being reported by ALL the methods yet poor old smallblock here isnt picking up a thing......interesting....
[Acer Iconia A500] smallblock:
Yes i tried them both. When i search the file, even for the word android. Nothing even resembles the androidboot.serialno.

The A500 manager spits out a more readable version but also without the serial.

Time for me to get desperate ? ;)

And btw was i right in presuming the V3.1 bootloader is indeed a HC bootloader ?
[Acer Iconia A500] citsong:
No need to get desperate. If your still on HC bootloader couldn't you make another nandroid? Could also try going back to stock HC and trying from there. I had to roll back from ICS to HC to get the BL flashing working but I didn't after someone recommended it and they said they also did that to get there cpuid by making another nandroid backup.
[Acer Iconia A500] dibb_nz:
not not desperate yet m8:) you got recovery and thats a bonus, so is being able to boot into an OS - so dont get too disheartened

dmesg reporting nothing is standard for HC booties

and yes V3.1 is the HC bootloader....

ok gonna take another track.....

we might just flash a pre rooted and unlocked stock ics rom from civs thread

then we avoid the whole cpuid thing full stop....what u think????
[Acer Iconia A500] dibb_nz:
well he is getting a cpuid reported but only the serial num 11 digits

as i posted: he needs cpuid for rollback with EUU's llike u used and i aint heard anyone doing rollback via update.zip - searching that now

think just flashing ics will do trick m8, dont think theres any issue with that

apart from borking it at some time in the future:)
[Acer Iconia A500] smallblock:
Well... that is of course an option but don't i still have the screen corruption with the HC bootloader?

I'll first try to make a nadroid backup to see if i can recover my CPUID from there (which i doubt) But hey.. let's try anyway :)

In any case i'm very grateful for all the help you're giving me.

I'll be back with the results.. or the lack off :)

---------- Post added at 07:00 PM ---------- Previous post was at 06:47 PM ----------

Ok, the serialno in the backup is the same as was returned by USBDeview when my A500 was running a A501 rom back in november last year.

Sadly this is not the one that gives a working SBK
[Acer Iconia A500] dibb_nz:
Taking Stock......

and u tried usbdeview on both pc's - i know your probly did, just checking!!!

how far along "trying to unlock the b/l " did u get, what method and did u run the sbk validation tool???

the 501 MAY have tiniest possibility to get u back to HC to flash a a500 rom -

par for the course with ics rom

yes u r correct, its just that i have been working on a project of my own - only barebones at this point and only for experimental purposes with my own tab - happy to risk my own.....someone elses is a different story, anyhow the rate i'm going it will never be an option:):):)

yep worth a go

no probs m8 thankful for the distraction really, had an accident at work, not too serious but just entails being horizontal with my leg up for most of the day.....thank heaven for ics coming out a day or 2 after it :):)....the last few weeks have flown by:D:D:D:D....i'd be like a caged tiger otherwise,lol:mad::mad::mad::mad::D:D
[Acer Iconia A500] smallblock:
I did the ICS stock deodexed update with the HC 3.01 bootloader kernel and everything just seems to be fine !!!

I don't even have a messed-up bootscreen like before. For the time being i'll leave it like this then and hope i can eventually update to the ICS bootloader in the near future.

Thank for the help and get well soon. Stay away from red meat !!! It might awake that tiger sooner than you like ;)
[Acer Iconia A500] dibb_nz:
Huh...wot....i missed something???? i only went to grab a coffee!!!!!

u flashed just now?????

OMG!!! and everything is sweet????

yep nothing wrong with that thinking m8, who knows, we may have found a new way to retrieve CPUID;s by then:) Was thinking too, a hard reset has been known to fix a multitude of sins:) it does wipe clean, clean so only to be used when e want to have a clear out:) button combo vol+,pwr, toggle rotation lock

:o:o gee fanks and your most welcome m8 anytime!!

:(:eek:;):eek::DLOL, errr i could but i better not. family forum n'all....nvm;)

keeping me from my red meat will do that, not recommended m8, hehehe:D:D:D

all the best m8, nice meetin;)
[Acer Iconia A500] smallblock:
Weird

It has gotten even weirder:

After i flashed the OTA ICS rom, i decided to experiment some more.

Now i WAS able to update to the ICS bootloader with the serial and the generated sbk that i found from last year (which didn't work at first).

Ok, after a day of messing about: Mission acomplished :)
[Acer Iconia A500] dadofsix:
Thanks dibb_nz. I am not sure what I am really looking for on this other that seeing what kind of cool stuff is available. I have the PCUID if I found what I am supposed to find correctly. Now I just need to get the rooting process so I can start on the rest. I have been a bit busy with the kids this last week as school is almost out here so final projects, concerts, ETC going on. Hopefully I will have some time this next week to play with it some more.

[Acer Iconia A500] subnoize soulja:
I have done everything like it says and it worked first try....When i booted up my tablet after flashing it says skrilax v5 0.0314 mul or something like that but when i open up acer recovery installer to see what bootloader i have it still says 3.01 do i have to re-flash or something or do i indeed have the ics bootloader.....also i keep getting random reboots like every 5 minutes what should i do to fix this?????
[Acer Iconia A500] dibb_nz:
Have read a couple of posts referring to this but not sure what the problem might be...I'd flash back to v4 and see if that will make any difference...post a question on Euclids Brother Acer Recovery Installer Thread...fire up a500 Manager and see what that reports your bootloader version as

Not liking the sound of those random reboots......

Could be an HC Bootloader issue ....

Flash v4 and a different recovery

Run ARI and a500 Manager and check versions

What Rom are you running??
[Acer Iconia A500] subnoize soulja:
I'm running civ's flexstriker rf1-v3 it was weird though cause after I flashed everything it went through with no problems and when it rebooted I got the Acer iconia a500 screen then it says up in top left corner loading v6 something ...sorry I can't remember what it says but I know it says its loading the ice boot loader but I rebooted my tab a couple of times and now when I open Acer recovery it says my boot loader is 0.03.14 MUL.... so I guess everything is all gravy now but beside my boot loader version it says click for important boot loader information. Is it supposed to say that? Cause I installed cwm 1.3.4 instead of the 1.7 touch recovery.
[Acer Iconia A500] amphi66:
The later versions (v4, v5, & v6) of SKrilax_CZ's patched, unlocked ICS bootloader pass 0.03.14-MUL to the command line. That bootloader info reminder is just that.
[Acer Iconia A500] subnoize soulja:
Is there anything else I need to do or am I good to go? I figured since I flashed the ICS boot loader I would be able to use HBO GO but I can't for the life of me get it to work it just keeps saying not supported on this device
[Acer Iconia A500] amphi66:
Should be good to go. See this thread for HBO GO: http://xdaforums.com/showthread.php?t=1647420. Note the startup/activation step - it works!
[Acer Iconia A500] dibb_nz:
Nice Find - HBO GO!!!

nice find amphi!!!

Also guys, couple of reports that rolling back to HC BL sorts out all sorts of weird problems some were having since upgrading to the ICS BL....

Be nice to know if its worked for anyone else???

If you do go back GRAB YOUR HC CPUID - the SBK Generator needs your

HC CPUID (15 Numbers) your ics CPUID (11 Numbers) will not work....

Right, I'm off to fastboot to HC - or try to:confused::confused:
[Acer Iconia A500] BrianDigital:
just got this from a nandroid back up 0x288424342e0b397 its longer than 15 digits, but so far this is the only thing I got that was over 11 digits, so does this look my cupid minus the 0x?
[Acer Iconia A500] dibb_nz:
Yep u all good the 0x0 is added and it doesn't matter if tits there or not, sbk will still be right
[Acer Iconia A500] Master_Ellis:
I found the cpuid in /sys/firmware/fuse/acer_cpuid using es file explorer long press acer_cpuid and view it with html text viewer/editor and it will display your cpuid. I'm rooted with locked bootloader 0.03.12 on ICS ota update. I can get the device in APX mode and download mode but unfortunately I can't seem to push the patched bootloader using nvFlash or BlackThund3rs method. Any ideas?
[Acer Iconia A500] dibb_nz:
with yr cpuid then EUU to roll back or fastboot to got to ics, coz u in apxmode already adb devices wont show anything so just jump to the 2nd command and hopefully it will kick you into bootloader mode, where you can flash a recovery then u can do what you want after that - if fastboot dont work could mean u still on old locked BL - hard to say not knowing history of tab - rollback to HC myt be better you can then check yr cpuid and OTA/Flash ICS

Check if adb sees your device:

adb devices

Boot into bootloader:

adb reboot bootloader

Fastboot Drivers will install.

Check if fastboot sees your device:

fastboot devices

if you get a ? here, its fine

fastboot erase recovery
fastboot flash recovery recovery.img
fastboot reboot

[Acer Iconia A500] dibb_nz:
Dunno wot happened to the reply I tapped out y/day so here I go again....

Give gersmas tool a whirl in the dev forum

Has "cpuid getta" flasher and unbricker so something 4 evryone:)

if u still looking for help then i need some more info

wot were u flashing

wot rom r u on now

wot b/l r u on now

were u trying to 'fix' something

the cpuid MUST be right

the drivers must install especially when u enter apx download mode

if u do not see on yr tab "entering download mode" or "acer apx mode" then

you need to fix this first before the flash will complete

the only way i have heard to fix the formatting errors like this is to downgrade to HC

If you find a better way please post it
[Acer Iconia A500] eppeP:
I have already mentioned this elsewhere, but I guess it is more likely to be found here.

You can also get the UID from the device in APX mode.

When in APX mode the device will answer the first read request with the UID.

A short description and some code for doing this with libusb-1.0 can be found here.

Since the Windows users can't use that I also made a variant for libusb-win32 with a visual studio project.

A snapshot of that can be found here.
[Acer Iconia A500] Vintage144:
Dibb you know of course you opened a mountain with this thread , 90% of the people in here dont follow the threads to the t! Thats where the trouble comes from, but Im glad someone cares enough to help , keep up the good work

@eppeP theres a tar file instead of a snapshot , im gonna try this on my netbook later to see if it work (linux)
[Acer Iconia A500] eppeP:
The tar file is/contains the snapshot of the repository. What did you expect?

For Linux you probably want the libusb-1.0 version.
[Acer Iconia A500] dibb_nz:
thanks eppeP

i may have replied on the other thread eppeP but just in case I didn;t:)

I have added yr post to the cpuid guide with due credit of course!!!!

I wish I could understand what it says, lol....all that code sends my brain to mush! I know what its saying but just dont comprehend it....i'll keep at it:)

[Acer Iconia A500] Raptor.X:
Uh, thanks for the tutorial about Blackthun3er's A500 Flash Tool, but I have a step that is not mentioned in it: a screen where it advised me to "Dump my BCT" before proceeding. I accepted, but it got an Unhandled exception pop-up that offered me to Continue or Abort. I chose to Continue but it remained stuck on "Staging and backing up BCT...". I flinched and thanked God I could reboot my tablet in normal mode again! What about that? I'm using Stock HC 3.0.1 rooted ROM.

Thank you.
[Acer Iconia A500] dibb_nz:
yeh, someone else reported same prob in the bootloader thread...i think Blackthund3r suggested to not dump the bct hit the blue arrow and carry on....the option to dump it was added in the 0.4 version and is in there purely for those tabs that for some reason or another have the "won't partition/format" or get stuck "download mode bootloader..." or wrong sbk issues.

If you have ANY of these issues you will not be able to use apxflash tool....i'd give the manual nvFlash a try i did a guide for that here http://xdaforums.com/showthread.php?t=1773323 let me know if u have any more probs:)
