[Q] Im sorry, Im paranoid. CWM Recovery - Acer Iconia A500

Im sorry Im looking around and Im seeing different methods, old answers on this for HC, new answers for that on ICS.
Im just trying to go about getting this Nandroid Backup & installing Thor's ROM and/or Reapers ROM.
Things I've already done:
Root my a500 tab- I have term emulator, Rom Manager, esFile Manager, Titanium Backup(already backed up all my apps+data)
Installed Acer Recovery Installer v2.74- clicked "Install Recovery Image"
Then this is where Im unsure, I tried manually (power+down) and with Acer Recovery to 'Reboot into recovery' but both ways I get this error: Recovery Verified Failed
In searching, Im hearing talk about Bootloader maybe isnt unlocked? Idk. Did I miss a step somewhere? Im sorry for the noob question, Im usually not this bad but Im just paranoid about bricking my device. Also, I hear CPUID. Not sure how these two things relate to this process, if someone can point me in the right direction.
Here are my specs:
Iconia Tab a500
Stock Android ICS 4.0.3
Kernel 2.6.39.4+
Image version: Acer_AV041_RV05RC01_PA_CUS1
Build Number: Acer_AV041_A500_1.033.00_PA_CUS1
Hope I dont get shunned for this Q

Just follow this guide step by step and don't miss any. I would read it through a few times before hand
http://forum.xda-developers.com/showthread.php?t=1622425
Then use this tool to flash the bootloader and CWM of choice (step 6 in the guide)
http://forum.xda-developers.com/member.php?u=4518389
and you should be good to go. It looks complicated but it is very straightforworward and was actually ALOT of fun for me.
As civato says in his guide:
PLEASE FOLLOW TO THE LETTER AND READ TWICE , don't be drunk , don't watch sports (we are men and can only do one thing at a time), don't take advice from your wife , girlfriend or whatever you need to feel loved , this is not like chopping for a bike or car!!! This is probably the most boring thing you are going to do in your life!
keep reading.... don't be a chicken , just do it !!.

[Q] Is there a guide for "notsonoob" noobs???

Hi all,
The reason why i ask this is because i would like to load some custom firmware onto my KF. I am currently running 6.2.2 (ota) and i am rooted with the android market and go launcher installed. I was looking through the forums and i was trying to find a guide... or something... that basically says what to do next. I didn't want to jump into doing something and make myself a $200 paper weight...
Any assistance/guidance would greatly be appreciated.
not really a guide but maybe a good starting point:
http://forum.xda-developers.com/showthread.php?t=1467013
Thanks for the reply, I was reading around and i DLed the latest KFU, and installed the twrp recovery. I guess what i am looking for is an order of doing things... I have a samsung galaxy s 4g, vibrant, and a P.O.S dart (all rooted w/ custom firmware installed)... all the forums with these devices had posts with an order of doing things so you didn't end up with an expensive paper weight...
this isn't me taking a stab at the dev's for the KF BTW, but maybe a suggestion... as i have no problem following good instructions to the S (at the end... get it? teehee) ... unless i'm sleepy.. then i miss stuff...
Any help... or even a posting with links (in order) of kinda what to do...
thanks all.
if you have a recovery (twrp in your case) then you have all you need to flash a other rom
- go to twrp
- make a backup of your current rom
- copy the rom you would like to flash to the root of sdcard (the .zip file)
- follow the instructions in the op of the selected rom (when and what to wipe/purge - it's different depending on the rom)
- flash the new rom
- reboot and be patient
- the first boot can need up to 20min

Chinese Atrix - Questions about FW, Bootloader, Root

Hi Guys!
I know, some people will hate me now because I opened a thread for that.
But the search did not help for chinese FW, so I wanna give it a try here!
I just got a chinese Atrix with the following information in settings:
System Version:45.2.14.ME860.ChinaRetail.en.CN
Android: 2.3.5
Baseband: BP_N_01.41.00R
Webtop: Unavailable
Kernel:2.6.32.9-00007-g9570040 [email protected]#2
Build number: 4.5.3-118_OLY-14
Superuser is already instaled and when i bootup the phone, "Unlocked" is shown in the upper left corner!
What I wanna know:
Is it rooted (yes of course, I think!)
Is the bootloader unlocked (never had a phone that says "unlocked" when booting up with an unlocked BL...)
Can I just flash CM9 for example or is there anything I should be aware of?
Sorry for beeing an Atrix n00b =)
And thanks for all suggestions!
The Unlocked text on the Motorola screen is an indicator that your device's boot loader is unlocked. I would recommend referencing the NOOB threads covering rooting and flashing ROMs for the rest.
Thanks for that!
But it's already rooted (super user is installed and I tried apps that need root).
What I wanted to know is, if I can just flash new roms or do I have to be cautioness, like many threads say: Don't flash back if u use build nr. xyz...

Check if you have cwm recovery installed. If not install the latest and flash the latest version of cm9 through cwm

Atrix 4g from Taobao 19 Apr.
Hi muhski,
I am in the same situation.
I just buy Atrix 4g from Taobao and receive it on 18 Apr.
When Gapps is not installed, I was very disappointed and call them to complain.
They ask me to send it back but I tried to get to know the phone more.
System Version:45.2.14.ME860.ChinaRetail.en.CN
Android: 2.3.5
Baseband: BP_N_01.37.00R (Yours is BP_N_01.41.00R)
Webtop: WT-1.2.0-163_11 (Yours is Unavailable)
Kernel:2.6.32.9-00007-g9570040 [email protected]#2
Build number: 4.5.3-118_OLY-14
Superuser is already installed and rooted.
Booting up the phone, "Unlocked" is shown in the upper left corner!
If you do a thorough search, you will know that to start to flash cm9, you need:
1. bootloader unlocked, machine rooted
2. clockworkMod (cwm) flashed
3. then flashing CM will be easy. Just put some zip files in root of sd card and then run ClockworkMod.
See but dun follow the cwm installation:
wiki点cyanogenmod点com/wiki/Motorola_Atrix_4G:_Full_Update_Guide
Your Atrix and mine are probably in stage 1.
Last night I tried to follow the old instruction in the link above to flash cwm.
But the fastest manner to run cwm is by installing Rom Manager instead.
Rom manager is super easy to use and I manage to get it to flash cwm in my Atrix. With cwm running, I boot from it and get cwm to flash Gapps in my Atrix.
Now I got cwm & gapps both running very well.
All my gmail, gPlay, gCalendar, gMap..... running quite well.
The next step I can make is to save cm9 zip files in the root of sd card and run cwm to flash it.
I am currently stuck like you. I wan to flash ics thru cm9 but worrying bricking Atrix. Moto may come up with ics for atrix real soon so I dun know if I want to wait.
Good luck
Sounds like you are on the right track. Once you have cwm flashed you can reboot, hold the volume down rocker as the phone reboots. Once you see another option under the "unlocked" text you can then tap the volume down rocker until you get to the recovery option, then tap the volume up rocker. This will bring up a whole new menu that you can use to clear cache, Dalvik cache and factory wipe.
When I flashed my first ROM I was very nervous that I was going to ruin my phone, but I have flash many ROMs since then some with gapps included and some that require you to flash gapps seperate. I have enjoyed many ROMs and have not run into any problems I couldn't fix by rebooting into recovery.
Good luck and enjoy the ROMs of your choice!
Hey guys!
Thanks for all your help!
First, I forgot to say, it's not the first time doing this stuff xD
It's my third android phone, so all is very similar to the Defy, but still I like to ask one time too often instead of crying about a bricked phone =)
What I have done now: Because bootloader was already open and cwm was already insalled, I could skip the hardest part and jumped right into flashing.
Ok, not really, because I updated cwm to romracers version (not really necessary, but everyone suggested it...)
Right now I'm running Neutrinos CM7 mod because other mods gave me randome reboots
First problem was: My Radio version does not work with this rom! "About phone" says "Baseband unknown".
I went crazy bcs I thought I got a broken phone from taobao, but smart as I am (hrhr) I made a nandroid backup before, flashed it back, and tadaa, with the old backup I had network connection....
So I googled a little more and found out about the Radio-Thread here.
Now I'm testing all the radios to ind the best one...
Good thing is, network connection is working now, bad thing is, it sucks my battery dry like a h**ker that gets too much money
@qqqqaa: does your radio version work with CM9?
Maybe I should try yours...
Can any of you with the Chinese ROM confirm that call recording works on your phone and if possible, do share a dump of your ROM.

I bought a used A500 that was already rooted.

I bought it and it appears to have ICS because the Android version is 4.0.3 but that is all I really know right now. I expect that it was never updated OTA though because the guy I bought it off had it for 2 months and he was not the one who rooted it. I was going to leave it as is because I bought it for my 10 year old daughter...but the camera takes very blurry, kind of grainy looking pictures.
I am not afraid to root because I had a Samsung Fascinate and I loved the custom roms I downloaded to it. It had been over a year since i had the Fascinate so i am a little rusty when it comes to all if this. My problem is not knowing where to start with this A500 because I am unsure what has already been done to it.
The guy who sold it to me said he did a factory restore, but when I ran the check root app it does state that it's rooted and I figured it was because there is a app called superuser on the device. I don't know what kernal it has. I don't know if it has a bootloader and/or the version number. I don't know if it has CWM and/or the version. number.
What is the best way to proceed? By the way, the tablet is very clean with absolutely no scratches anywhere. Not a bad buy for $175 with a leather case...
Setting > About tablet. That should tell you quite a bit of info about it no?
download the acer recovery app , it will tell you what Bootloader you have and what recovery
Thanks for the replies! When I get home I will check. I don't want to brick the thing. I ordered a micro SD today and I will get it in 2 days so there is no hurry for me to proceed. Is it worth it to keep it rooted? Is the OTA ICS good enough? I don't think my daughter cares if the tablet is overclocked but if the roms are much better than stock than I would keep it rooted and then download a preferred rom.
Vintage144, in another post you specified that there is a Acer recovery beta...will I need that or would I just get the one from google play? Also when I find out which version of recovery and bootloader I have...I am not sure what to do with the information. Could AfterOta help me accomplish what I want if my goal is to try and fix her camera issue...either by going back to stock or updating the kernal and rom.
I don't want to seem like a noob but my only rooting experience was with my Fascinate which I did everything from stock. Now that I am not coming from stock, I am unsure where to go with what I have. It's like trying to get to a goal but not sure what step to start at. If I was starting from stock I could follow some of the threads here but it's not stock.
What info will I need to post here to let you guys know what is in my A500? I know that the Android version is 4.0.3 , what else will I need to post?
well the beta copy I believe is at thors tegra forum , but its by euclids brother (thats his name on xda) anyway if you've upgraded your BL it will tell you version you have and might give you accurate Recovery as well, if the device is only for your daughter and she's too young to really do anything I would stick with a stock rom and realistically I would upgrade the boot loader , why be left behind?
Theres no reason to root if you dont plan on doing anything major with it,that being said you wont be able to get a newer Boot Loader or custom recovery without it, and custom recovery is well worth the effort!
You guys are the pros so I will take your advise. I don't mind it being rooted and if there are some really nice roms I expect my daughter would like the different looks...it would seperate hers from others.

With all the above information what would be my next step?
Sorry
Recovery Version: RA Revamed for Iconia 3.16
Damn auto correct!!!
You're already running an older custom rom...
You have root - your words not mine...
You can download another custom rom, put it on the sd card/ internal memory and reboot into recovery. You need to wipe cache, dalvik cache and do a data wipe(factory reset) after which you can install zip from sd card. Go to the rom zip file you put there and install...
Wait until it boots...
I don't know if you're running the new ICS bootloaders or not.
BEFORE FLASHING - make a nandroid backup. If things go bad then you can go back and restore the tab to before the flash...
It's worth getting your CPUID and keeping it safe somewhere and you might think about installing the ICS bootloaders (I'd do it just to be sure I have them) but thats you're choice...
Good luck...

Probably want to hold off on flashing roms a second.
He's running an HC Bootloader. I'm 99% sure of this. Reason, RA Revamped 3.16 doesn't work with ICS Bootloaders. So you can install an ICS Rom, but, it has to be an ICS Rom for the HC Bootloader. And the performance under HC BL is not near as good as ICS BL.
I would do like UltraMag mentioned as far as install steps and such. It's how we install roms.
Check this thread;
http://forum.xda-developers.com/showthread.php?t=1622425 (steps 1-6)
, and install an unlocked ICS Bootloader and a CWM 7 or 7.2 recovery. Then install one of the Roms made for the ICS Bootloader.
I know AfterOTA will do some of this for you. But this thread gives a good idea of what's going on.
Thanks for your help. I will be getting my micro sd card on Friday. In the mean time I will do a bunch of reading about the things you guys told me to do...again thanks a lot. I really appreciate the help.
I am the kind of person that really wants to know what I am doing...I don't expect all the answers, I just don't want to brick this device.
Forstir9,
Moscow Desire is a great dev on this board, his information about updating the bootloader is dead on. I recommend reading the entire OP in that thread, and then re-read section listed as Automated Flashing Tools, it really helps tremendously if you are a person familiar with root, but not extremely dynamic with making these changes.
I've rooted several BN Nooks and my A500 many many times and love it. I had the Honeylicious ROM that you listed prior to what I'm currently running. KYJ had a great HC ROM with that one! Personal preference currently for me on the ICS ROM is FLEXREAPER from Civato, poster of the referenced article from MD above, you can find that ROM info here: http://forum.xda-developers.com/showpost.php?p=22964651&postcount=1 Lots of cool features and step by step directions, which are what UltraMag69 listed in their post. There are many many different options though and I recommend reviewing several and then settling in on one when you find the one that fits your (or your daughter's) preferences best.
If you enjoy doing this and playing with the tablet your daughter may not keep it and may end up getting something different, because you may have too much fun with it...good luck, have fun, don't be scared to try things and ask questions (after you read first), and most importantly BACKUP BACKUP BACKUP...
Good luck,
-DB
Let me get this straight then.
1) boot into recovery and make a nandroid backup.
2) within that backup I should be able to find the CPUID on my sdcard...I will want to write this down and the write it down again somewhere else...out this number on my phone and computer...pretty much don't lose this number.
3) follow steps 1-6 from the link that Moscow Desire posted.
I am going to go with the Flexreaper rom...should I go with the extreme one or is there another Flexreaper rom that isn't extreme?
4) I think the 6 steps above will install a ICS bootloader
5) find and install the newest recovery
I only have 2 questions
How many of these steps does the Afterota app get Rid of?
Should I use the Acer recovery app to install the bootloader and/or the recovery?

First off. Thanks for thinking I am the "God" of the 501". Yeah, I know it pretty well.
Second, Ultramag, is is one of my right hand men. So I suggest you heed his advice well. I always trust his judgement. Am sure he has puled my arse out of the wringer a few times. Well, maybe not, but you get the picture. Some of us on XDA, support each other. That's how it is. I just noticed the bootloader version, And being one who likes flashing experimental code, well, I noticed.
So;
1. ALWAYS make a recovery backup. Then, restore it to make sure it works. (lots of people don't do this and they get fubar'd later).
2. UID. Seriously. Ok, the link on the many ways to get it. You don't want to get it, well... your;e pretty much fubar'd
http://forum.xda-developers.com/showthread.php?t=1624645
3. He has the normal, and one with a kernel you can overclock. Your choice. Really, if you don't OC, then you run the same as the original. Please don't ask me the names of Civatos roms. The extreme will be fine for you. Just don't overclock it if you don't want to. Only difference is the kernel. Not the OS.
4. Yes.
5. For recovery, I would say CWM 1.7.2. Should work for you. 1.7.0 is also ok. Publick recovery is ok too.
6. Never ran After OTA. But hear it is good when you already have ICS.
Forget AcerRecovery. You will already have bootloaders and recovery installed.
MD
Know I'll probably get a bashing out of this but there's a V1.7.3 recovery on the site that must not be named (cough, tegraowners, cough) that supports the Aroma installer - on Thor's ICS rom anyway...
Just thought I'd throw that in too...
I am ready to do a backup...it's asking me what I want to backup...it has a (X) next to the following...
Boot
System
Data
Cache
Flexrom
Is this correct the way it is?
EDIT: ignore this post I didn't see page 2 -_-
Sorry that I didn't post this in Friday...but I really want to thank everyone for their help. It went very easy and it want too much different than my fascinate.
The camera still takes grainy pictures and a few apps has sounds issues but she really likes the rom a lot.
Thanks again for the help.

How to install custom rom/recovery for Acer a500?

I just rooted my Acer iconia tab a500. I am on the official ics 4.0.3. Can anyone provide step by step guide how to install custom rom for this tablet? Also which custom rom that you recommended? I thanks

Hi guys welcome to the weird and wonderful world of the acer tab!!!!
Things are very different with this device, whats 'normal' for other android devices is not 'normal' for our tab!!!!
So first of all, dont try installing cwm or a rom the 'normal-this-is-the-way-I-did--it-on-myphone', you will end up with a brick!!!
2nd, you both have working systems at present, so we'll try to keep it that way.
Open up a file explorer and navigate to this:
/sys/firmware/fuse/acer_cpuid
One of the first things that are different is this: acer_cpuid
It should look something like this:
288424344009597 - now u need to add a 'zero' to the front:
0288424344009597 - this is your cpuid, back it up in multiple places if need be, just dont ever lose it - IF anything 'goes wrong' at any time you will NEED this number to save your tab from eternal brickdom!!
3rd once you do get your 'cpuid' go to the 'sbk generator' here.
This generates your 'sbk' or secure boot key and will give you something like this:
0x93588800 0x33CE8901 0x0BED6D03 0x30737899.....
OK then, now you have your cpuid/sbk you can start thinkning about what rom you want to install on your tab.......
Read the OP(Original Post) of your desired rom. This will tell you EVERYTHING you need in order to flash it - remembering always that 'Acer' does not do things the 'normal' way!!!!!!
Most of the custom ICS/JB roms on here all require the 'patched / unlocked bootloader'... In fact, even installing a custom recovery, cwm, twrp or public recovery, for the first time....will require the BL to be 'patched' first....and yes, even flashing this is not done the 'normal' way....tho the process can be complicated there are PLENTY of guides and auto tools to make it easier for you....
The 'patched bootloader flash' will also include a 'custom recovery' too, and you can choose from 3-4 options....amazing but i'd advise to use cwm 1.7.3, until u get up and running, after that you can go crazy flashing anything you like!!
So basically there are 5 main steps to getting a custom rom installed.
1. Install the Acer Drivers and the android_sdk drivers
2. Get your cpuid and generate your 'sbk'
3. Your desired rom is on your external sd card
4. Put your tab in 'apx mode' which allows u access to download mode
5. Install the patched v8 bootloader/recovery - either manually using nvFlash or using the auto tools.
Personally I prefer the manual nvFlash method, if you get an error it will at least give you an error message...the auto tools will just get 'stuck'
Check the 'bootloader' thread OP for a guide to manual nvFlash and the patched bootloader package here
There is also a step-by-step in my sig!!!
If you want to use the auto tools then apxFlash tool, or afterOTA tool you can find both in the 'bootloader' thread. And a step by step for apxflash tool also in my sig....or this excellent one here by user jdgM3NT4L here...
please be sure to read these posts very carefully and if there is something you do not understand then please dont hesitate to ask , there are plenty on here who will help you thru the process....AND its easier to offer help at this point rather than trying to do so when you've bricked it.....
As far as roms are concerned, you cant go past 'civato's FLEX roms' very stable and no issues i'm on cm10 and havent had a problem with it.....Of course it depends on what you require but I'd start with one of the flex ones.
Most peeps here have no trouble with this process, those that do, usually try things the 'normal' way, then find out they need their cpuid/sbk to get out of trouble and of course they dont have it....this makes things most difficult.... there are a few tabs with motherboard issues that have needed to be sent to acer....other than that, he only other issue you may have are driver related, check out the cpuid thread for anything driver related and lots of other background info too....theres also a zip file there that has a mini-sdk kit, to save u downloading the full android-sdk....
i think thats all i can think of at the moment, sorry for the long post and all the caps and bold text - just trying to save you alot of unnecessary grief...
Good luck with it all and remember....in this forum things are not 'normal' :laugh::laugh:
Wow, a lot of stuff to do just to flash a from huh. Lol
Sent from my A500 using xda app-developers app
Lol, as always preparation determines the success of the final outcome....and yeah with the tab 95% of yr time and energy is spent preparing!!! The actual flashing process takes only a few minutes...
Of course u could revert to hc 3.1 where everything is 'normal' i.e. one click root, flash cwm, flash rom, done....
Gosh, even hc 3.2 was locked down and unrootable....
So in the grand scheme for us to even be able to have stable ICS roms, let alone cm10 on the a50x.is.purely down to those wonderfully clever devs we have here..who were never gonna let a.locked bl, get in their way..
OK its complex I'll admit, but stock ICS is c**p and the lives of our tabs extended past wot Acer ever thought....and guys like gersma and.blackthund3r have built auto tools to make things easier
Anyways, its.well worth the
effort and is actually alot simpler to do than it is to describe how to do it...think of.trying to explain how to ride a bike and writing all those steps out....much easier to help them thru it by just getting them on the darn thing and doing it....dontcha think??

Oh, one other thing, you'll wanna back up all yr personal stuff, music, photo's and wot not especially going from one build to another, and most of the custom ROMs require a complete wipe and format of yr data partition too before install, just so u know!!

wow dibb, thank you so much for a helpful response!! Really enlightened me about how far off I was about the update process (compared to updating phones) and yet close enough to what I had to go thru for the Viewsonic GTab.
I'm currently on stock 4.0.3 rooted for A500. I have obtained my cpuid and SBK. When I go to recovery mode, I see a droid with triangle and exclamation mark. I tried flashing twrp but I still saw the same droid. I now know that I need to flash a different bootloader with recovery included.
My question is that if I flash the new bootloader which will allow me to put a custom recovery, during that process will my current ROM be removed or wiped out? If so, what do you recommend for backing up the app in the current stock ROM? Titanium Backup? BTW, I don't have an external SD card; all I'm using is the internal 8GB
Thank you for your help!!
def need external SD , it will help out alot

Yes u need the v8 bootloader to get a recovery installed...
Always check the original post of the rom you install for special instructions regarding bootloaders.....this applies to all custom Roms even stock pre rooted ones.
Yup TB to back up yr apps and data - dont restore immediately...make sure everything is stable first.
If u dont have an ext. SD card, the EUU method doesn't require one, and as slayinu said, it would make it easier if u had one especially for the update.zip methid
Im sorry...
I have the a500 running ota 4.0.3....well from the official app. I have it rooted and running superuser yet I downloaded the Acer recovery installer app from the market and get the recovery verified failed message when booting into any custom recovery and the dead android with the exclamation mark....I know I need a patched or an unlocked boot loader but I cannot find one I downloaded the afterota but it doesn't do anything on my computer...idk what to do the frustration is gonna make me break this thing and just go buy a newer tab running jb ....help please!

Seems weird afterota "doesn't do anything"...did you install the drivers?? Did it give u yr cpuid/sbk you cannot do anything without this AND if u muck things up its the only thing that will get u unbricked? Are u using a micro USB cable? Do u have USB debug enabled?
If u go to the root guide in my sig you'll find d.load links and all the guides to help u install the v8....take special note of the boot.p file u need to rename or delete in /system....
For more info on getting yr cpuid/sbk see the cpuid guide in my SIG or the sticky in dev forum...

obviously..
I'm too dumb to figure this out...idk how to get my cpuid none of the ways in your "where's my cpuid"guide worked.I don't want to stay stuck on ota 4.0.3 but apparently I have to..thanks for your time and your advice,unfortunately I wasn't able to use it properly.
Well, it seems it's not just you being dumb ...
I tried the same - original OTA 4.0.3 and rooted my A500. Now tried to use the 'AfterOTA'-Tools, but getting stuck in step 3 of 4 (maybe i just need to insert a SD-Card in the Tab?).
Just got no idea, what to do now - the only thing i know is: before flashing, i need a open bootloader, but i've got no idea how to do that. The Guide linked in this posts: http://forum.xda-developers.com/showthread.php?t=1622425 is just confusing me more and more
After a reading a few times, it seems to me, that MY next step should be:
"Automated flashing tool" (STEP 5= Going into APX mode see Q&A or use A500 manager)
-1-Reboot your tablet and make sure on your tablet: "Settings" -> "Applications" -> "Development" -> "USB debugging" switch on.
[...]
-It will ask if you are ready (click yes if you are)

Is it correct, that THIS will help me to patch/open the bootloader?
Or do i just have to follow this as a next step to create a patched bootloader:

Hi voodoo, no, neither of you are being dumb!!! It CAN be a complicated procedure, we try to make our guides 'simple' but theres ALOT that can go wrong
Yes the last link you posted will flash the patched bootloader!!!
- but basically this is what SHOULD happen
Note: The only way to get a custom ICS rom on your tab is with the v8 bootloader by skrilx_cz. This must be flashed via nvFlash/apx mode.
Note:The only way to install a custom recovery like cwm or twrp etc is with v8 bootloader.
Note: You cannot use Acer Recovery Installer unless you have the v8 installed.
Note: Rom Manager does not support our Acer Tabs...please don't use it to flash 'anything'!!
OK heres an overall view of the process:
1. Install Acer and adb/fastboot drivers
2. Retrieve your CPUID...
3. ...and use it to generate your SBK
4. Download your ICS or JB rom and copy to your sd card (internal or external)
5. Enter apx mode to begin the flash!!! or use apxFlash tool
5. Use balckthund3rs apxFlash tool and follow the instructions: hint: dump and save your bct!!!
5. If using civato's manual nvFlash method - Put your tab in apx mode and run the .bat file
5. AfterOTA Tool is only for those tabs which have OTA'ed to ICS!!!
The main issues you will have with the actual flashing process itself is a partitioning error or a bct error - and both of these are easily fixed...UNLESS your tab in one of the few with a hardware fault which only a new motherboard can remedy
Once you get the big white "PASS" on your tab, boot straight to your new custom recovery, do the FULL WIPES and flash your new rom....DONE!!!
Well ... i now used AfterOTA - but not in a virtual machine - now just natively installed on my macbook via bootcamp (windows). Worked. I now have a V8-Bootloader (the tab shows me this when iam booting it up).
Whats the next step to flash a new ROM? Iam ready to do that? Or is there any other step needed by now?
Regards, Tom
Edit:
I now just tried flashing a custom rom - so i copied the *.zip to my USB-Stick (FAT32) - because i read, i can use an USB-Stick as an micro-sd card.
Tried booting into recovery-kernel - worked for me, but the only thing i can see: a lying android with an red sign ("!").
Did i something wrong?
Oh dear....if u had a stock rom on there then its overwritten
your newly flashed recovery....you need to delete or rename
the "boot.p file" in /system..then reflash the v8...
The very next step should be to enter recovery and flash your
desired rom....
So, it now just works everything.
Used Acer Recovery-Manager to re-flash the recovery - worked fine for me.
But: i tried several 4.1 and 4.2-ROMS ... is it correct, that there's no Google Marketplace anymore on 4.1 and 4.2?

Not new to root, new to iconia

Ok, here is what i have , I have a IConia a500 rooted with, link for forum and files, using ICS Root
(came with 3.1, ran all the iconia updates, to 4.0)
everything went fine, now... i am familiar with flashing roms, i have had a few android phones and have rooted them, and flashed custom roms on them. that is what i want to do with this, after doing over 4 hrs of reading, I have confused the crap out of myself. there is a lot of talk about things that i dont know much about..
-CPUID's
-ICS recoverys (bootloaders?)
Basically, all i want to do is add the CM Jelly time mod, but im not 100% on how i go abouts that? what do i need? i have the files and gapps, etc., i know i need a full wipe, but what recovery do i use? CWM? do i temp flash it or, pernament? after watching a few videos, i still dont think im ready, i diont want to brick this thing. i just want it to work with that rom. thanks any help and clarity is severly appriciated!

1. get yr cpuid and save it multiple places open a file explorer and go to /sys/firmware/fuse/acer_cpuid
2. then go to /system and rename/delete recovery-from-boot.p file - this will prevent your custom recovery being overwritten with the stock recovery.
3. have your custom rom on yr ext SD card, ready to flash ONCE you've flashed the unlocked bootloader
4.To flash the v8 bootloader you need to use nvFlash and there are a couple ways if going about that...
a) manually by using the guide in the OP of civato's BL thread
b) using one of the auto tools like afterOTA or apxFlash - links also in that same post...
c) you'll also get to pick a custom recovery and it will be flashed at the same time - cwm 1.7.3 is recommended until you're running stable
d) From yr cpuid - generate yr sbk - how to do that is in the same OP
5) once flashed, boot straight to recovery
6) Do a nandroid backup then the wipes
7) Flash the rom
8) Reboot to recovery and wipe again
9) Job Done!
notes:
Everything you need to do this is in civato's BL OP - sorry can't post the link but its stickied in the Dev Forum
the afterOTA tool,
- saves all yr uid details etc in a txt file
- flashes v3 bootloader -
- it also installs the needed drivers too
- its pretty good at what it does...
seems some are having wifi issues with jellytime but the dev is working on this
you've done the right thing by asking questions before attempting anything, wish everyone was like you...if my post isn't clear then please let me know....for those of us used to the way things work with our Acer, its hard to remember how difficult it seemed when we were new!!
good luck

ok, thanks !
i have used the afterOTA and it would let me select the recovery i wanted to boot, is this permanent or temp? right now on my phone its the cwm, but i remember on my Nexus S, they recomended just pushing it, that way it was super hard to brick.. basically i just need to know if i need to run the afterOTA tool everytime i wanna boot into recovery? thats why i like my CM 10 for my Galaxy Nexus, i can choose to boot into it,
I think the hardest part of these simple tasks, is that there a 20 steps to something totally new, I used to unlock iphones for a living, I never knew what i was doing exactly, i had a rough idea, but i did know how to cut and paste. even going from my NS to GN its always been a few hrs to root/unlock, Being familiar with a lot of the steps, theres more with this tablet! EI, CPUID, APX? tons of warnings! the other things are the abriviations, they can be confusing.. soo
this is the only thing i didnt understand, does the OP dumb it down, or can you??
d) From yr cpuid - generate yr sbk - how to do that is in the same OP
what is sbk, and why do i need it?
thanks again, i really appriciate it!
also, what is a LEAK? leaked rom?

no m8, once you've 'flashed' via the tools its permanent -
there are flashable zips around (for recovery) but again, you need the unlocked bootloader first....once you have it then you can flash anything, anyhow you like. Even Acer Recovery Installer will work fine and you can flash a rom from there too, though that may require the paid version from memory.
the only time you will 'lose' the unlocked bootloader/recovery is if you need to rollback to HC - specifically 3.2 -

yeh I'm hearing you - this thread is a perfect example!!! I'd love to be able to say...root it, then flash cwm and the unlocked bootloader IF you want it, lol
Acer locked this baby down tight as - and if it werent for the work done by alot of the devs here, we'd still be stuck on factory stock.....The success these devs had is proved by the fact that there are still so many new folks coming here looking for info and help

sbk = secure boot key....as you've discovered 'root' just isnt enough to flash anything...to flash anything you need nvididas nvFlash program PLUS the key to unlock the encryption which is hardwired into the ROM of the memory chip itself -(haahhhaa I think thats right) - The CPUID is unique to every tab (and this too may be hardwired into the chip as well) the sbk is a hex number based on the uid. there are a couple of generators around to do this for you, blackthund3er has one and so does vache....you've used afterOTA so this does the genration for you automatically - you can see it in the text file you saved
thanks again, i really appriciate it!

yeh back in the day before acer released ics, 'someone' got hold of a leaked ics version, and this is where alot of the work was done on unlocking the bootloader...by the time acer got round to releasing ics - we had a more stable version than they ever had
So now you're unlocked and rooted, have all your ID's backed up and done a nandroid you can quite happily flash to your hearts content!!!!:good::good::good:

ok after OTA generated my sbk and all that info, saved it to my computer... how do i unlock the bootloader? i want to install CWM, do i just need to download a file then use the advanced tab?, from cwm im sure i can get around, also, i dont know what apx mode is, ill do some more searching, thanks again.
ok this is really hard to do with windows8, my god, i have to do a lot of running around, i think im just going to give up, now, APX drivers are nto working, fml
had to manualy add the drivers, it was a pain the ass, now its all donw, hopefully i can get it going now!

standard tab choose first option...keep an eye on the status bar while its flashing..should not take longer than 10mins.
You must then boot straight to recovery and flash yr rom from yr USB key
don't have to worry bout apx mode but yr tab should display.either Acer apx mode.or Acer download.mode at stage 3 of 4 in tool status bar.
if u.muck.up you'll learn all u ever wanted.to know about apx.mode

EDIT: the last option on the Standard Tab
DON'T FLASH THE FIRST ONE!!!!!!!
