Hey guys, I'd first like to thank everyone posting guides on the forums, has made my job a lot easier. I'm currently in the middle of trying to root my telus hero with the gold card method. I made the gold card, i think anyways, but before i go ahead and run the RUU file to downgrade, I want to make a nandroid backup of my phone. I downloaded the recovery image which is supposed to have nandroid v2.2 in it, but I'm not to sure how exactly to use it... I'm kind of a reallllly big nub.

From my understanding, as I saw it, I believe that the RUU's are safe, since they're HTC approved images, just that the gold card allows you to revert to a lower version of an HTC rom. Think of it as the RUU's as an official update, but an older official update, and the gold cards make your phone seen as a phone that can accept any update (new or old). So there will not be any harm when you run an official update like this unless your computer crashes midupdate or you pull the battery..or the cable gets unplugged.
Nandroid backups can be produced using the recovery image (i call it a menu since that's all you really see from it), which is covered later in a tutorial if you're reading one. This recovery image is applied after a downgrade (the downgrade gives you the ability to have root access, which is i believe necessary to get the recovery image installed), and thus be able to make these nandroid backups. The nandroid backups then get saved onto the SD card to which you can transfer to your computer for safe keeping. This ensures you can revert to an official rom with previous settings applied in case of an awry custom rom installation. The nandroid backups can also be used for nonofficial roms that you've deemed stable when you tested them, and this can be done as many times as you want.
I'm not sure if I'm entirely right, but I believe I have the gist of it. If anyone can correct me for any errors or can elaborate more, please feel free to share After all, we're all new at one point, hopefully veterans of this will chime in and allow us all to learn!
Also, welcome to the forums! Glad to have you!!
alright, so if I understand correctly, I first need to root my phone to gain root access to perform these nandroid backups?
I'm using this guide" Get started rooting Telus HERO130! (No need for QMAT!)", I'd post a URL but it seems that since I am a new member I'm not allowed to post URL's. I've gotten up to step 6. When I run that RUU file it says its going to erase everything on the phone, so I decided its probably best if I backed up my phone before I try this in the event that I mess everything up horribly.
Is this possible without having root access to use the recovery image with nandroid on it? or am I just having another noob moment?
thanks for the help!
I'm trying to restore my Acer Iconia A500 back to the stock/ original ROM so that I can grab the official update in July. Is there any way to do that? I really like the custom ROMS, I just want to revert to see what it was like.

And, of course you made a backup via clockworkmod???? eh?
Why are so many not making backups of their tabs before installing unknown software?
There's lots of threads about this in the forums with instructions already. And this belongs in the General forum, not development.
Yes I'd also be interested in this. I have the droid x so when ever I want to revert to factory settings theirs a program on the computer (rsd lite) I use to revert it. So I almost never backup my roms. Now on my iconia they don't have such program. At least that I know of. So I flashed a rom on my iconia and didn't make a backup of my current one. I tried fixing it by flashing stock_acer a500.zip I thing by dexter don't quote me on that one. But it was the emea version so now its stock european and I live in america. Help is apreciated.
I'm a flashing person that has flashed many times on my phones. I forgot to make a nandroid backup of my original rom myself...so I'm not judging. I would say, flash honeyvillian, as its the closest thing to stock I've seen.
But, if your already flashing, I wouldn't want to grab the official anything...someone will post it once it comes out.

because we are impatient and stupid
I am running to get someone with a tablet of my country to get back the STOCK ROM in case of... I am going to see if I can deal with the shop to root and recovery on SD Card the stock rom so I will be able to have the stock rom...
For USA version 1.104.02, Check out this post.. You'll probably want to skip flashing the stock recovery until you know the system will boot normally.. So from this post, run itsmagic, flash boot, flexrom and system, in that order. Preferable from an adb connection. The tablet will freeze while flashing system. Give at least 5 mintues to make sure it's complete.
You may need to do a data wipe if it bootloops (that's why you should skip flashing recovery). Once it's booting normally, you can flash the stock recovery if you want.
Alternatively, you should be able to replace the files in dexter's stock update zip with these files. But I haven't looked at that zip, so I don't know if system is an image file or a archive file.
Thanks for the replies quick question though. How do in run its magic is their a command for ADB or do I acess it via clockwork recovery?

I too would like to restore to the 3.0.1 stock rom, however my backup of the stock rom got corrupted somehow. I know it had to be something I done, but know not what it was I did. Any help would be much appreciated. Or would it be a better idea to flash the 3.1 leak?
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!!

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...

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)

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?
Hello,
I've just gotten my Galaxy S4 GE; before I did anything to it, I was wondering if there were an official site containing the stock images, like there is for Nexus devices (https://developers.google.com/android/nexus/images).
If not, how can I extract the ROM (and possibily the Recovery)?
Also, as an information, I've updated right away from 4.2.2 to 4.3 via OTA. I thought that the image might still be saved somewhere onto the memory...
Thanks for your time!
Could anybody please help or give me a hint on where to look at. I'd like to have a backup of my stock S4 GE!
Thank you.

As far as I know, there is no stock image provided for the i9505G by Samsung or Google. Since this isn't a Nexus device, it doesn't have the same access to original software images.
I think the best you can do is to root the device, boot from a custom recovery, and then do a full Nandroid back-up. This keeps the device very close to stock and you end up with a path back to this state. Here's the process I used to get to the point where I could do the Nandroid backup:
http://forum.xda-developers.com/showthread.php?t=2365555
Use this version of CWM instead of the one listed--it's the newest version and supports Nandroid for the i9505G:
http://download2.clockworkmod.com/recoveries/recovery-clockwork-6.0.3.6-jfltexx.img
You can find more information in the i9505G Android development forum, particularly the sticky thread at the top.
Hello!
Thanks for the answer. I'll try to do as you said. Just two things:
- Will it be possible to run the CWM without flashing it? If yes, how?
- Is the "nanadroid backup" an option on CWM labeled with this very name? (Sorry for this qustion )
Also, by chance I found this: http://forum.xda-developers.com/showthread.php?t=2368121
Isn't a dump what I'm looking for? If not, what is it then?
I understand that there's no website that provides stock images (sort of stupid from Google), but can't I get the image of the 4.3 the phone downloaded when updating via OTA in any way?? Isn't it still stored somewhere for when I do a factory reset?
Thanks again!

Following the rooting process outlined only boots up your phone using CWM recovery and doesn't flash it. Just make sure that when you're done and choose to have CWM reboot your phone, if it asks you to overwrite your phone's recovery, you choose "NO".
The backup isn't called "Nandroid" in the CWM menus. You are just given options to do a backup or restore, which uses Nandroid.
