Little Overwhelmed

I just bought g tablet. I need some help on where to start.
I read below to use Z4 root:
http://www.androidpolice.com/2010/12/08/how-to-unleash-the-power-of-the-viewsonic-g-tablet-and-turn-it-into-the-best-performing-tablet-on-the-market/
Also read here that I have to set up ADB first then root with SuperOneClick
http://forum.xda-developers.com/showthread.php?t=827209
Is it necessary to set up ADB? Can I just use Z4 root?
Android police say next step would be installing ROM like
Cyanogen 6.1, TnT Lite or ZenPad. Which one can be recommended?
I'm not sure what all this means I just want to follow some instructions to get this tablet working better.
Is there a way to back up before I try this so I can go back?
Sorry for all the questions but this is very new to me.
Thanks for any help.

I cannot figure out how to do anything

Start with the FAQ area, in my signature. It has information / links on the alternate ROM's available. They are rooted already and can be installed using the device's own firmware update process.

A little comfort knowing I'm not alone but I want to get it working. I need a tablet this size with flash so I can watch my movie at work

I was the same way with roebeet and a few others u will be savy in no time.
Make sure u get clockeorkmod 1st installed.
Partition ur sdcard and back up frequently. You can't break this thing with those things in hand I promise.
Purchase root explore and titanium backup for the rest.

I assume I need to do root first, right?
Is there instruction somewhere for installing clockworkmod?
How do I partition the sdcard for this operation?
Thanks!

that video helped me greatly,now after doing this is there no return to the manufactures OS? And it is recommended to clear the cache and how is that done?

clockwork instruction is here

Yes you can reflash back to the original OS, like if you needed to return it or something. Once you experience something different I promise you wont want to go back

It is not a requirement to partition your card. I have not (at least not yet- unless forced to with a future rom) and have had the G for over a month now and went through all TnT versions.
Currently using TnT 2.20

The problem with the guide linked above (-http://forum.xda-developers.com/showthread.php?t=865245) is that I get stuck at step one. I simply cannot for whatever reason flash Clockwork Mod 0.8
It just gives me the giant EXCLAMATION MARK /!\ and doesn't do anything. I'm following the directions perfectly.
So is this an issue with hardware revisions or something? Because as far as I'm concerned this tablet is busted if the exact thing that works for all of you doesn't work for me.
EDIT: Finally found a different SD Card and it worked. Don't know why. The card that didn't work was a stock 1GB Sandisk, card that worked was a stock 512MB Sandisk. Weird.

You can install Clockwork and flash ROMs without rooting your tablet first. You also do NOT need an additional SDCARD in your device; I did ROMs several times before adding an SDCARD.
Your best bet is most likely TnT Lite, although VEGAn is fast becoming the best ROM available and it's still in beta.

If root is not needed to flash CW or roms why even bother rooting it?

The roms root for you, so no manual root process. Putting CW on has a bunch of advantages.
Clear cache, data and Dalvik cache
Back up entire current rom and restore with it if problems
Fix permissions
Boot into usb storage mode and access internal space, even if device will not boot up.
Break out of boot loops
No complete need for recovery folder
That is some of the main reasons it is prudent to install it. Life line

Having root on the device is akin to having superuser/administrator rights on your home computer. It is necessary to have for the system administrative type applications you may want to use (e.g., TitaniumBackup) to help backup and restore your data / applications.

ok at first i was just like you guys did not know how to flash any ROM, or how the tablet actually did it or the necessary files needed at the required location, first off when you first connect the tablet to your pc gotta choose turn "turn on usb storage" on tablet, than go to "my computer"(where you see all your hard-drives) and open the new storage from the tablet there you will see a bunch of files ".android_secure,.br, android" etc,etc, there also should be a Folder called "Recovery" which contains the actual command that tells the tablet to do an update. inside there should a file labeled "command" and when you open it with "notepad" it should say "update_package=SDCARD:/update.zip" this what is going to tell the tablet to put a new ROM when you do the power up holding the power and the vol. + buttons, once you verified the "recovery command" is there, copy your "update.zip" folder to the same area where you see all those other "android" and "recovery" folders after that, power down, do the power up holding the power and vol. + until you see that it is replacing the ROM

Finally got my gtablet working with TnT lite, Market, Flash After getting confidence in doing this I then root my phone(Droid Increible) and install wireless tether so I can connect my gtablet to my phone. Thanks to XDA and the great members!

I have to say this is a nice upgrade from what it was out of the box, but my issue is spending 4 hundo on something I have to mod myself to make it work, because as it is now I have voided the warranty by doing this. Any other suggestion on tablets that are better than this?

we all feel you there..

[Q] just got my nook color looking for some clarity

so i just bought my nook color today and i have some questions, i was searching around in the android development forum and their were about 50 different methods of doing everything.
i am experienced with android and how to do anything just if somebody could post up links in an order i need to follow to be able to get CM7 on to it.
if possible flashing to nand would be preferable but if all we have is SD support thats okay too
thanks for the help guys
also i know i will likely get flamed for this thread but just know i am experienced with android and i have ran it on a non native device before (htc vogue).

My go-to link for flashing CM7 to the internal memory:

You can get just about anywhere with the nook via two steps:
1) run autonooter for your software version (THIS is for 1.1, obviously for the other versions it will be a different thread)
2) use the market to download ROM Manager, then flash the CWM recovery and download 7.0.2 from the app (or pull a different CWM zip from the forums onto your card if you prefer) and flash.
Simple enough

thanks, i was reading it from the app so i missed the 2nd part about loading it to my sd card thanks for all the help guys im going to try this now

so i did the rom manager thing picked nook color (old) that might have been the wrong choice but now it wont boot past recovery it just keeps rebooting into recovery
also it wont allow me to flash anything it says i have the wrong prop=encore help somebody

okay got that fixed thanks to one of the tutorials on here (thank god thought i bricked it)
so cm7 is booting now how long does this thing take, mine has been going for like 10 minutes but its not like bootlooping is this just because the tablet builds are huge or do i have cause to be uneasy (nook builds like stock software def didnt take this long)

http://wiki.cyanogenmod.com/index.php?title=Barnes_&_Noble_Nook_Color:_Full_Update_Guide Just in case
First boot will take 5min+.

This isn't your Hero!!! I don't think you can brick this thing.... The Nook always tries to boot from SD before internal memory!!! I had a hell of a time getting CM7 to load originally (at least 10+ minutes). Once you get it loaded, put away that SD card you burned the recovery image too.....Put a new SD card in, install Rom Manager, and flash recovery to it from Rom Manager. Once you get there you can Nand and flash stuff just like you do on your phone.

[Q] Acer Iconia Stuck on "Android" screen

Pls help...after installing Acer_A500_4.010.40_COM_GEN1 through CWM...then i do factory reset, right now my acer iconia is stuck at "android" screen...I can't go to Thor CWM since its not installed...
how to solve this problem ? thanks

more info needed
Did you clear all date cache files before updstiong.did you confirm the md5 on the update.zip.these are a few diagnostic things.I would try taking your SD card inserting it into your computer using SD formater format the card to fat.redownload the update.zip file check the md5 to insure its not currupt.after moving it to SD card.the put back in tab and reflash.if this does not work try diffrent SD card. If that fails find a fifteenth download thee is prob a issue with that file
Now all of this is in the developer sections.You should have not tried flashing your device without knowing what to do if it went wrong.details about all I have mentioned are in the forum threads. OVER AND OVER AND OVER.
Please stop and read to understand your device
Good luck

Problem solved by flashing stock rom...thanks

Same problem
I also tried to return my Iconia A500 to stock and now my Iconia sits at the Android screen and will flash the word Android every few minutes.
I tried flashing it with stock roms I got off this site. I used Acer_A500_0.000.00_4.010.10_COM_GEN1_1310535068612_9b84abb1. I did decrypt it like Thor posted to do.
After the flash the Cockwork Mod is no longer there. My problem is very much like the one posted here but no fix is listed. I hope some one can help me.
I have been poring over this site for a while trying to find the fix.

Dunno why that would happen, I see the file size was only 47mb don't sound right to me...
I had similar prob with update.zip, just couldnt get it to work - lost cwm in the process and ended up using timmydeans method http://forum.xda-developers.com/showthread.php?t=1307539 to get cwm and rooted 3.2.1. This wipes all your data so be warned.
Method 2 here http://forum.xda-developers.com/showthread.php?t=1276227 supposedly keeps your data but installs an unstable 3.0.1 which you then use to root and install cwm. Its difficult to use due to the instability so make sure you have these apks on your external sd to make life easier:
acer recovery installer and iconia root, just do a search on the forums to find them.
To go back to full stock I used the EUU package from here yesterday http://forum.xda-developers.com/showthread.php?t=1113878 to get back to 3.0.1 which worked real well, dunno if it wipes all your data coz i'd done a full format and wipe beforehand. I got all my OTA updates after the flash so now waiting patiently for the ICS OTA to roll out you will need a pc and your cpuid.

Surrender
Thanks I tried all these very good suggestions but still cannot recover my tablet. Looks like it is time for me to call Acer and find out what they will charge me to fix it.

hmmm, its rather unusual that none of those methods worked for you, without the system throwing up some sort of error unless you trying to revert to stock after trying one of the ICS leak roms - this involves a downgrade using an EUU but using a totally different method.
Did you remember to remove the update.zip from your external sd after you flashed the stock rom?
Are you saying it boots but just not all the way into the OS? i.e boot loop
sorry to ask all this but it may be of help to others experiencing the same thing
Flashing back to stock normally does the trick - if theres no SOS or LNX checksum errors - which you have not reported...

Please Help im a nub :(

well get myself a second hand a500 32gb, with 3.2.1 on it...
im a total nub with this and the only tab ive rooted is an archos 7 G2 and all i had to do was put the update.zip on the sd card and it rooted/flashed itself.
How the hell do i do this to my a500, i really need to use ad-hoc as its the only way i can get the internet on it.
any guides need to be retard proof. i have the rom i want to use already lightspeed ICS. Ive put it on the sd card dont the power and V- but nothing happend i just get the android green robot thing with an ! on him :/
TIA
Foxor.

hmmm if i install the ICS update would i loose all my app/games/photos?
if i didnt could i then use the root tool for the leaked version to root my tab?

Use timmydean's method. http://forum.xda-developers.com/showthread.php?t=1307539 this will put you with a rooted 3.2.1
Works like a charm, and is as easy as following the PDF instructions. I have used it for my A500 and just used it today on the wifes as well.
It will wipe your data so backup your apps with Titanium or the likes to external sd card.
You can then flash the ROM of your choice in CWM recovery.
Read the instructions TWICE for the ROM you are going to flash. And make sure to do a full backup of the rooted rom incase anything goes wrong.

i'm a noob too
Hi I got my a500 on Wednesday and read heaps of posts, so many my eyes are fall in out, lol.
My tab updated itself to 3.2.1 which I found out cannot be rooted without a custom rom??and to get a custom rom on it, u need to be rooted.
Waiting to update to ics, but ain't got it yet, so I,m stuck too. At least ics can be rooted so waiting impatiently for that ota update so I can start having fun, good luck

Yeah thus is my first tablet also. Guess each device is a little different. Gotta learn another device.

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

Please, me too. I just bought mine too and is rooted, but my cell phones were much easier than the tablets. Either that or I just don't have the patients anymore. Maybe a dummies way to install custom rooms on a500? Lol.

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??

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...

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...

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?
