v4 Flash "cwm new" gives HC CPUID!!!!

Hi guys,
Using civs guide and nvflash method - i flashed the v4 unlocked BL -
all went well and i was done in 4:-5 mins max....thanks civ
In the options for recovery flash I chose No.5 "cwm new". so after the flash i jumped straight into recovery and backed up....on the recovery home screen
i noticed it displayed my cpuid - and not the usual 11 digit number but my
original HC 15 digit number!!!!
This is great news....if its correct......can someone else confirm this???
Is this due to the v4 BL or is this due to HWCBN recovery???
I believe the recovery images are specific to the BL or maybe the BL requires a
specific recovery not sure on that, anyone know for sure????
Does this mean that those who do not have their CPUID can retrieve it using
"cwm new"????

Previous recovery added a "uid.txt" file to the backup, I don't see that at all with the V4 bootloader & Touch v1.7 (for some reason v1.7.2 hangs at 'Booting recovery kernel image'. By "cwm new" are you referring to ezterry's "Public CWM"?

"cwm new" "option 5" thor 1.7.2

Oh hell, just check...i thought "Option 5" cwm new was thors 1.7.2 -ARI 2.99 beta not picking it up just booting in now....
yeh they all save uid.txt just not the one we need for sbk
"cwm based recovery v5.5.0.x (thor2002ro rev1.7.2) Iconia A50x"
is what it says. Displayed on recovery home screen CPU UUID: and my orig CPUID
I got rid of 1.7 b/c touch buttons had a mind of their own - and have been on TWRP since flashing v3 -
Not sure why you got the hang with it had you powered of and rebooted after the flash - I use ARI to boot to recovery havent tried button combo - but i will now
loving 4 way boot menu - wish we could have that option from the pwr button

The new 1.7.2 version of CWM automatically displays the CPUID, it is a new feature that is mentioned in the changelog for the recovery. It also has a boot into apx mode (download mode) feature added too.

I realise that m8' that's not the point I'm trying to make!
The point is this
It displays yr original HC cpuid
No other method I have come across can do this once u flash any type of ICS based rom
Its why everyone bangs on about keeping a copy of ya cpuid once u leave HC . The only way to get it (till now so it seems) Is to downgrade back to HC??

And what's even more interesting, is that when I ran my Old UID into SBK, and my new UID into SBK, it generated the exact same sequence. I noticed this about a month ago
Also, now, after several bootloader flashings, and rom testings, my UID is now exactly the same as my original HC UID
Ohhhh.... UID merry-go-round

I'm looking forward to your findings.
Hopefully it will work in different situations, only had the chance of testing and debugging it on my tablet.

will this work on my PB Liberty Tab (G100W) running HC 3.0.1?
my android version is 3.0.1
and build Number is PB_G100_1.013.02_EMEA_GENS

great share!

yes, with this you can install recoveries, root your tablet, and even return to stock through the update.zip method for eg. selling your tablet !

If this a500 version works fine for everybody, i intend to make a a501 version of it. I advice not to use it on A501 because on ics it seems that the a501 has different bootloaders.

I want actually to install ICS Custom/stock rom with ICS bootloader,
Could you tell me the steps to follow,
Once I install ICS bootloader while I am on HC stock, then I cant boot, so should I flash a ICS rom from CWM immedietly after installing ICS bootloader? or I have to install ICS stock Rom first then ICS bootloader??

1) best to put the ota update zip on the root of your sdcard
2) boot your tablet with vol min pressed until you see recovery image loading
3) then you will end up or in the actual recovery you installed or it will begin flashing the ota ics
4) when you are on ics and you have enabled usb debugging, you can then flash the matching kernel for the ota you had installed (eg version 1.031)
(without the correct kernel on ics, certain recoveries wont work)
5) after reboot, flash recovery and bootloader again
6) remove the sdcard from your tablet, remove the update.zip and put for example flexreaper or any other cwm rom on it. put sdcard back in your tablet.
7) reboot your tablet into the recovery and flash your custom rom you put on your sdcard in the previous step, and your good to go.
you should have done the update.zip method in the first place, or go to ics through the official update system.

Many thanks for the Guide,
I will try as guided...
for Packard bell, official ICS updates are not rolled out yet...
only one doubt in the item 1 you mentioned is internal SD or external SD??
thanks again

Ok I tested it , my conclusions:
-Tablet info section= 10/10
Very easy getting your cpuid and SBK , one click , nice.
-Back to stock= 8/10
I get it but I do hope the new users get how it works so maybe more info with link to full packets thread and link to decrypter thread .
-HC= 9/10
In browse , I would remove the custom bootloader , for HC you only got the A501 and A500 bootloader , for some it would seem that they can flash a custom HC bootloader like on ICS. (My opinion , thinking on newbies)
-ICS=10/10
Everyhting what you need is there.
-Kernel and root = 7/10
Tricky stuff here , maybe better to provide the full stock kernels also (no sys rw hack)
Also I would make clear that only installing the root doesn't give you system/rw acces without installing the hacked kernels.
And make clear that these are not tweaked or OC kernels.
(you are free to add kernels from my thread and if you need a combination just pm me)
-extra stuff =10/10
Overall 9/10 , I flashed a few recovery's and bootloaders using the pre build in packages and using browse and picking my own stuff , really nice and easy !
Maybe a idea for later and do the same as my m8 blackthun3der and allow prebuild packages (.a500apx).
For the A501 , if you download the flash tool from my guide you will find the bootloaders for the A501 in there , if you can't find them let me know !
edit
One question , did you use the correct bootloader to go into apx because for ICS V6 it is a different one then to use when you install HC bootloader. (reason)
Download my tool package from the guide and look for
dlmodeblhc.bin = for a500 getting into apx when installing HC bootloader
dlmodeblhc501.bin = for A501 getting into apx when installing HC bootloader
dlmodeblics.bin = for a500 getting into apx when installing V6
dlmodeblics501.bin = for a501 getting into apx when installing V6
and then you got the HC bootloaders
hcbootloadera500.bin
hcbootloadera501.bin
And ICS bootloaders
ics_boot_unlk_V6_500.bin
ics_boot_unlk_V6_501.bin

Works perfect for me! Thanks! Makes things a lot easier

i meant external sd
I just went back to full stock hc 3.01 on my g100w, stock bootloader and stock recovery, through the update zip method. (one ive downloaded from vache's romlist), i enabled usb debugging on that system and imediatly flashed ics bootloader 3.14.6 + thor recovery v1.72 from the "ics" tab on my program.
Rebooted the tablet afterwords and i could not boot into honeycomb like you say. Then i removed the external SD card from the tablet and put ota ics version 1.031 on it, put it back in the tablet and rebooted the tablet with vol min pressed.
Thors recovery came up, and i did :
1) "choose zip from SD card"
2) in the next menu i choose "update.zip"
3) in the next menu i choose "yes install update.zip"
4) it starts flashing the official ota ics
5) after flashing go to "wipe menu" and do : "wipe data" , "wipe cache" and "wipe dalvik"
6) after that go to "power menu" and reboot your tablet
7) go through the initial android setup (choose wife, choose language etc)
8) enable usb debugging in your android settings (its in the "options for devellopers" section, just above "about tablet"
9) fire up afterota v1.00
10) go to the "kernels and root" tab
11) if you installed ota ics v1.031 then install the corresponding patched kernel, in case of v1.033 choose the other one etc. and start flashing the kernel.
12) if kernel flash is done, shutdown and reboot your tablet into android
13) once you see the android lockscreen press "reconnect tablet" on Afterota (on "tablet info" tab)
14) go to the "kernels and root" tab in After ota and press the "copy" button to copy the cwm root package to the internal sdcard of your tablet. If its done your tablet will automaticly reboot. If you see the android lockscreen proceed to the next step
15) press reconnect tablet in Afterota, if connected proceed to next step
16) go to the "ics" tab in Afterota and flash your recovery of choice again, the only difference between "install a500" and "install g100w" buttons is the bootloader logo, so its not a desaster if you think you've hit the wrong button. If see pass on the screen of your tablet proceed to next step.
17) shutdown and powerup your tablet holding the vol min button pressed to get to the recovery, go to "install from zip file", "choose zip from internal storage", choose "cwm_hc_ics_root.zip", choose "yes install ..", go back, "power menu", "reboot" and let the tablet boot until you see android lockscreen.
18) now in Afterota, reconnect tablet, go to the "extras" tab, and "remove recovery killer script"
Tadaaaaaaa : fully rooted ics + custom bootload + recovery

You have some really good tips here, i'll try to import them into the program in the next release. Thank you very much for reviewing the program !

Many thanks again mate,
You have already typed a lot for me, sorry to bother again,
OTA HC 3.0.1 was rooted before you flash ICS bootloader from your program??
If I need only a working ICS rom on my Tab, not rooted no CWM, can I stop at the instruction no.6

A500 / A501 bootloaders have tiny difference (aside from the bootlogo, which I changed back to "green Acer"). I shall probably make V7 universal.
However, can you update the tool packages not to flash V3 - it doesn't allow custom BL updates via. CWM (full support for that is in V5 via both CWM and fastboot).

Confuse about unlocking bootloader

I bought this tablet and I want to install a custom rom. I am not interested in dual booting. I found a thread titled
"[GUIDE]A500/501/G100W-Installing ICS V8 UNL-BL & CWM Or back to HC BL(24-6-2012) "
Information there is a little confusing to me. On my A200, the steps were simple, unlock boot loader, install CWM and then root/install rom. Then I was done. Seems like I have to do more steps on theA500, which I don't mind I just want to do it right. Is it my understanding that the thread is for dual booting, it also talks about CPU ID.
I found another thread that talks about Afterota v1.09, do I only need to just do this for what I want to do or do I need to do more? Why would I need to install a ICS bootloader, I have ICS now, stock, doesn't it already have it? I tried looking at the Q/A but I just ended up more confuse.
Could someone just give point me in the right direction so I can go about unlocking bootloader and installing CWM so I can install a custom rom.
I have Android 4.0.3 Kernel Version 2.6.39.4+ Stock
Side question, my unit is a 16gb model but its only reading about 12.71gb, does anyone know why?

A500 works differently: the stock ICS BL is locked and cannot be unlocked from fastboot. What we can do however, is to flash custom BL, since we know the device "Secure Boot Key". In general the term "ICS BL" means my patched BL, which you can find in my signature. There is a bunch of guides to get it flashed on the forum, and blackthunder made a tool to simplify the process.

Alright, so I do not need to do
Option 1 use Afterota for A500/G100W IF YOU ARE ON OTA ICS and follow this thread
or
Option 2 , keep reading.... don't be a chicken , just do it !!.
then I just need to use blackthun3r tool? I tried it but when I launch A500APXFLASH.EXE it ask me for a SBK and the guide said this "the v0.4 APX flash tool will give your SBK automaticly !!" but its blank it has not given me SBK automatically. So I was directed to this thread
http://forum.xda-developers.com/showthread.php?t=1810618
which has the "SBCalc "
which then directed me to
http://forum.xda-developers.com/showthread.php?t=1624645
which reads
GET ME MY CPUID!!!
There are 2 different cpuid
ICS CPUID has only 13 digits/characters and is your "serial no." as reported in settings, on your sdcard cover and on the box
we are only interested in the 15 digit HC CPUID this can only be got:
(1) From a PC using Blackthund3rs A500 manager
(2) From your device using Terminal Emulator App
(3) From USBDeview must have previously used the Tab under HC with the PC you're using
(4) From a uid.txt in any Honeycomb-cwm backup in external_sd/clockworkmod/backup/"your_HC_backup" folder
(5) From adb devices if you're running honeycomb
(6) From cwm 1.7.2 via on screen display and a text file - great if you are on ICS already
(7) Master_Ellis has posted that he found the HC cpuid in /sys/firmware/fuse/acer_cpuid - add a zero to the front!!!
please if anyone uses this let us know if this is correct!!!
thanks Master for the heads Up!!!
(8) Gersma's most excellent OTA Toolmakes most of this thread obsolete!!!! Thankyou Gersma for all you've done OTA Tool is all anyone ever needs....
Features :
I don't get it though, I thought you said all I needed was the blackthund3r apx flash utility. I'm really confuse, can you specify what I need to do?
I went back to the original thread where the blackthund3r flash tool is and it clearly says
"3-When it askes for your SBK you need to type it in , the v0.4 APX flash tool will give your SBK automaticly !!"
But I do not see the SBK come up automatically. Man all I want is to be able to flash roms ;/ Can you specify what I need to do please I do not want to jump the gun here and brick my device. I see two files in the zip file, a500 Manager v1.0.2 and Apx Flash Utility v0.4

Alright I figured out what I was missing and manage to go through the whole process easily. I have Apex now but how do I install CWM or TWRP? WHen I go into recovery I get a dead android.

Lots of trials and errors lol so I figured out Recovery only works the first time, is there any way to have CWM on there permanently?
Update
Recovery always works now, wasn't sure if that was a glitch or what. Anyways, thanks Skrilax, that little piece was enough for me to get going. I understood the guide once I knew what I needed which required me reading a few threads. Guide kinda needs to be tweaked a little.

Recovery not sticking is due to having a stock rom. Rooting with ICS Root 7.1.1 stops this
Sent from my Iconia A500 using Tapatalk 2

Just noting: stock recovery won't work, and if you ever applied OTA, booting Android will overwrite recovery, unless you remove the updater. And for the guides, all will work, some are more automated, some less.

[Q] Bricked every time i falsh ICS Bootloader

Hello every one

So you can boot into the OS OK??
Did you root it?
You may have to take an OTA or update.zip to 3.1 first and flash the v8 from that as I'm unsure it will work from 3.0.1
but after that i couldn't flash any ics rom or ics bootloader

is their an "apx device" listed in hardware and printers or in your pc system tray?

go to the root guide in my sig and Make absolutely certain you do the first 4 steps in that guide.
d/l the latest apx Flash manager tool v 1.0.2 and use the bundle market in it to install bundle #17
OR
use civato's nvflash package instead as this requires your tab to be in apx mode (black screen/pwr lite on) to work AND will give you a more specific error if it fails.
Once the flash is complete BOOT STRAIGHT TO CWM and flash your cm10.1 rom
THEN Do a factory/data reset and enable wipe of /data/ media (in mounts/storage menu) wipe cache and dalvik cache too. Reboot to cm 10.1!!!
Please do all the steps in the order they are given -
If "it doesn't work" we will need you to tell us what is or isn't happening and where in the process it fails!!!
Good luck

It's rooted because it is a custom ROM with CWM Recovery 1.3.4 by Thor
Is it OK to flash the ICS Bootloader from HC 3.2.1 "Civato-FLEXSTRIKER-HC.3.2.1 R6-BASE"?
is their an "apx device" listed in hardware and printers or in your pc system tray?
do you get "acer apx mode" displayed on your tab?

Yes their is an "apx device"
and my tab shows "entering apx mode..." or something like that ! with ACER logo
go to the root guide in my sig and Make absolutely certain you do the first 4 steps in that guide.
d/l the latest apx Flash manager tool v 1.0.2 and use the bundle market in it to install bundle #17
OR
use civato's nvflash package instead as this requires your tab to be in apx mode (black screen/pwr lite on) to work AND will give you a more specific error if it fails.
Once the flash is complete BOOT STRAIGHT TO CWM and flash your cm10.1 rom
THEN Do a factory/data reset and enable wipe of /data/ media (in mounts/storage menu) wipe cache and dalvik cache too. Reboot to cm 10.1!!!
Please do all the steps in the order they are given -
If "it doesn't work" we will need you to tell us what is or isn't happening and where in the process it fails!!!
Good luck

"USB drivers from the Android SDK" on step 1 maybe that is what I need
So I'll give it a try and tell you what happens.
And again thank you for your help.

Well..
I followed your root guide and used Civato's nvflash package, lots of things happened.
file no 1 is the first result
then file no 2 , here is where I get stuck in apx mode again !!
errors i get :
error formating partition 4
error formating partition 6
The thing is, not every time I try to recover my tab it works
I succeed only once of every 15 tries to recover my tab.
so maybe some partitions are messed up or something.
One time, I tried to flash Civato's nvflash package again , and after few times the bootloader was flashed correctly, but the recovery wasn't !!
So, I tried to use fastboot to flash the recovery ... and it went O.K
After that, I restarted to recovery, formated data (factory reset) , cache , delvik cash, flashed the rom, rebooted the tab ...... but nothing happened !!
and i'm stuck here
I've done lots of searching around the forums and most of them recommend BabSector or tdv4_rollback_rom or EUUs .
only EUUs are working, and even that would work one time of around 10 to 20 tries.
do i have to flash the primery kernel via fastboot , and if so, how to get the kernel from the rom?
thanks in advance

Boot to fastboot mode
Fastboot erase userdata, cache, system and flexrom - use separate command for each partition, note any write errors and post back.
Fire up apxflash tool....you MUST dump, save then use your tabs BCT when u get to that window - this should repair the bct error shown in the 2nd text file.
Also tick "show nvflash commands " this will show any read/write or partition errors..
If you get partition errors run babsector (d/l in the root guide) and follow the steps I posted there.
Boot directly to recovery and try flashing a rom again

No u shouldn't have to flash a kernel its included in the rom.
A full and complete erase is required first
(If there are errors here like can't read/write or bad data....your tab is toast) if not,
The bct error must be repaired next, else your tab won't flash any rom at all, even if the tool says PASS
Then reset your partitions with babsector.far
(Any errors like those listed above....your tab is toast)
With all the errors you're having its pointing to a faulty chip, flashing should not be this problematic.
Be sure to follow the direct order of repair....otherwise you'll be compounding errors

Sorry for my late reply
I didn't run apxflash tool I have try something before that I have flash a HC rom over the ICS bootloder "it is wrong I know" but it went OK and the tab boot to the rom!!!!!!!!!
So now I have ICS bootloader with HC rom. what is going on ??
I have a new long work "13 hour" and I can't spend alot of time with my tab but I want to understand what is wrong with my tab
I'm really thankful for your time.

Well, thats different!!!
Are you running stock HC or is it a custom one?
Which recovery are you using?
Download Acer Recovery Installer from the market, it will tell you your bootloader version. You will need root priveleges to run this

ok lets start with the bootloader and why we need it...
On most android devices your first step to flashing a custom rom is to root so you can flash a custom recovery....
With our Acer Tabs since HC 3.2 the bootloader is locked...meaning even having root access did not give us the ability to 'flash' a custom recovery - its just not possible....the only way to do it is with the "patched" bootloader - I don't know how the magic works, but the devs managed to find a way to 'trick' the system into allowing their version of "patched bootloader" to be installed which would allow the flashing of a custom recovery....and there is a very specific way of getting this patched or unlocked bootloader onto your tab....this is with a program called "nvFlash" which runs via "apx mode" or "acer download mode" using our tabs unique ID, the cpuid.....to make it even easier The devs created a "package" which will nvFlash the patched bootloader AND a custom recovery all in one go!! Once we'd done that all we needed to do was to boot straight to recovery and flash our desired ICS or JB rom!!!
In the beginning, way back in the day....some folks weren't at all comfortable going to these lengths just to have a custom rom, so some of the rom cooks gave us the choice to upgrade to the patched bootloader or to stick with the HC bootloader, by flashing a custom HC kernel after the bootloader flash....this is what you were alluding to earlier??
Most roms now only work with the patched bootloader i.e. skrilax_cz 3.14 MUL -v8
keep in mind these are ICS and JB roms...
I hope that provides a bit more understanding on the bootloader thing and why we need it...
Now back to your original problem, not sure why you cannot flash a JB rom, have you tried it again??? I just cannot think of anything that would prevent you from flashing anything except an HC Rom - You might wanna ask the question in the JB rom thread...there might have been specific steps you needed to take to downgrade from 4.2 (can't think what though) or others may have posted similar problems...sorry couldnt help you out ....
...but let us know how you get on, good luck!!

Finally I have moved from HC to JB and that is how :
- ubdating the bootloader from v8 to v9
- nothing changed trying to flash any rom I already have
- then and I don't know why I download an Android 4.3.1 from TegraOwners forums [WIP]A500/A501 JB-MR2(4.3.1) - V8t6

flash the rom and everything went OK !!!

Update fails - want to flash custom rom - need some advice

Now here's the situation:
I'm still on an older ROM version (4.2.1 - see attachment)
A while ago my tablet told me there was an update. I wanted to get it, it downloads but it always fail to apply the update.
What I've done to the device so far is that I've used motochopper to root the device and got rid of some ASUS apps.
So since it refuses to update, I've decided to unlock it, flash a custom recovery and get myself a custom rom.
But I've read a lot about people bricking their devices and I doubt it'll be as easy as it was on Nexus 4 and Nexus 7 - so I need some advice on how exactly to do it.
Recently I found the thread that enables us some sort of nvflash although being on JellyBean. They were talking about a specific version of bootloader and I'm not certain if I have this bootloader since I'm on an older JellyBean version. Of course I would like to use this bricksafe as well - just in case
Can someone lead me to a guide or instruct me how to do it? I don't want to brick this device
Thx in advance

This THREAD has all the info you need to do NVFlash. It's based on 10.6.1.15 something bootloader which I believe is the same as the latest Asus official. If you're on 4.2 rom, you can flash the flatline img. and generate the necessary files from there. Once that done, you can use either the provided CWM or the latest 4.2 TWRP to flash any compatible custom rom (4.3). Have fun.

First of: thanks for your reply
Guide says something about bootloader 10.6.1.15.3 - I still have an even older one (10.6.1.8...) - will it still work?

Yes, that version will work because it is on the 4.2 bootloader.
Sent from my TF300T using xda app-developers app

Only works on unlocked device?
Ok I'll try like this
These are the steps I would do: (I pray someone to look over these steps and correct me if I'm wrong )
1.) Go to asus site and download unlock_v8 and run it so to unlock my tablet.
2.) I go to androidroot.mobi and download flatline_tf300.img and nvflash-tools-win32.zip (win32? Hope that does not stand for 32-bit and hope it will work on 64-bit)
3.) I reboot my device into Fastboot (don't know exactly what that means "Please note that for transformer tablets the fastboot command might require the option "-i 0x0b05"" - at this stage the device is already connected to the pc and just in case it's not in fastboot I should run this command?)
4.) I use cmd.exe to type in these commands. In which directory? In the directory where I unzip the files from nvflash-tools-win32.zip? The guide is not too specific on that.
5.) I type in "$ fastboot flash recovery flatline_device.img" (I know for device I use tf300) which will flash the recovery.
6.) I reboot my device (let android boot?) and reboot again into recovery. (power + vol down?)
7.) I select "Advanced - Wheelie" and Step 1: Flash AndroidRoot BL and find myself with a custom bootloader.
8.) It says the device will power off. Automatically? However, I boot into android and after that reboot again into recovery mode.
9.) I choose Step 2 which will generate wheelie blobs
10.) I follow the on screen prompt to retrieve my blobs (anyone has a screenshot of that? Or is it self-expalantory?)
All this time the device is connected to pc via usb?
11.) Now I reboot my tablet into APX mode - after Step 10: am I still in recovery or booted to Android?
12.) If my tablet is recognized I type "$ wheelie --blob blob.bin" into cmd
13.) Then I will type in the commands to obtain the backups
Still got a few questions though. The device is connected to PC throughout this whole procedure, right? Where to start cmd (do I have to put the files from nvflash-tools into a specific folder from where I start cmd.exe?)
And after this procedure is done do I need to flash anything else? Or will I be then equipped with a working recovery that allows me to flash custom roms?
Thanks in advance for anyone who's taking time to answer my maybe uninformed questions but I'm kind of having troubles following the guide
