[Q] [q] flashing kernel? - Acer Iconia A500

Im running hc stock 3.1 4.010.07. I would like to know if I'm able to flash a kernel to over clock my a500 without erasing my data on the device. I would like to be able to keep my data intact. If I am able to can someone post a link to some info so i can work it out.

Yes, your data should remain intact. However, you'll need to root your device first, then install ClockworkMod (CWM) via Acer Recovery Installer in the market. Reboot in to CWM to install your kernel. BUT - first make a backup!

thanks
Thank you for the links and the info. Did a little searching and discovered thor2002ro has a kernel and decided to go with his for now. Flashing wasn't as hard or scary as i thought it would be

brick Nexus S

Hello. i am new to the android family
i have a nexus s GT-9020T
i have rooted my phone but without setting the clockworkmod reovery.
today i was playing with the rom manager and downloaded one of the rom from the list. after installation i was unable to start the phone only seeing the google logo with the unlock logo.
i went back into the recovery by typing flash recovery recovery.img etc.
run a restore and restart the phone but still not work
my nexus s is 2.3.4 by the way.
please assist
What "restore" did you run?
Go here: http://forum.xda-developers.com/showthread.php?t=1056062
And download the full rom:
Model: i9020T
Full Rom: GRJ22, KD1
That'll revert your Nexus S to the latest completely stock 2.3.4
Then you can flash recovery again and go back to clockwork mod and go flash another rom or whatever.
Remember when you're flashing a new rom you need to wipe data and cache and dalvik cache.
i run an restore from the backup that i made before installing the new rom using clockwork mod recovery, its part of the option when installing the rom using the rom manager * click box - backup * etc something like that

Next time don't use Rom Manager to make backups or flash roms. It's stupid and can get you issues like you're having.
Anyways, try wiping data and cache then restoring the backup, do it in Clockwork Recovery.
Let it boot, first boot always takes a while, 5-10 minutes. If you see the boot animation freeze, stop and restart, then yeah it's screwed up, otherwise, just let it is.
If still not working from your backup, do what I said in previous reply, just restore to stock 2.3.4 then re flash clockwork mod and start over with the rom you want to flash.
thank your nxt. i have found the real problem. it was not my backup problem or the rom that u provided. it was the version of my clockwork mod recovery. i was using an 2.x.x.x to restore the phone which is why it doesn't work. everything work fine now after i flashed with an 3.x.x.x and restore the phone. one question thou, where can i always find the newest clockwork mod recovery release ? thank you very much

Or just use ROM Manager to get the latest.
That's the only thing I use ROM Manager for... getting the latest Recovery.
thanks again nxt. if you don't mind really ...i have one more question. i know the phone intend to uninstall clockwork mod recovery once its restarted. i know there is command type into the cmd to avoid the phone uninstall the clockworkmod reovery and make it permanent in another word. I didn't run those command when i root my phone because i don't know if its good to make it permanent like.... hmmm like if there will be a 2.3.5 coming next month..just saying ok... with a permanent unofficial recovery will cause a problem?

Are you running custom ROM? If you are, it's already made to not revert back to stock recovery. If you leave it stock recovery you'll get notifications for firmware updates by Google, but remember that applying those to a rooted phone might screw things up too.
the blue one is stock recovery right?

Don't remember. It should only have like 3-4 options.
thanks again nxt. no i am not running an custom rom. i mean not yet. i planed to try one from the rom manager download section then my phone couldn't start after installation and now i have restored my phone from my backup using the clockwork mod recovery 3.x.x.x.

[Q] Downgrading 3.1 to 3.0.1

i wanted to know if i can downgrade from 3.1 stock to 3.0.1 using acer recovery tool. I want to downgrade because some of the apps that i would like to use keep force crashing on 3.1. i have tried reinstalling the apps and nothing works.

If you made a nandroid backup using clockworkmod (you should have), just do a full restore. ba-da-bing.
The acer recovery tool you mention is just for installing clockworkmod, it won't install a rom itself. clockwork mod does that.
i didn't create a backup so i guess i'm out of luck.

Maybe you are not... Dexter provided a stock rom on his first post here:
http://forum.xda-developers.com/showthread.php?t=1121790
Check this post. flashing those 4 files (don't forget itsmagic), will put you at version 1.104.02_GEN1_COM (U.S. Stock).
Skip flashing the recovery if you don't want to lose ClockworkMod.
http://forum.xda-developers.com/showpost.php?p=14967064&postcount=206
If you want a specific version, ask someone to uplaod a ClockworkMod backup of boot, system and flexrom and use ClockworkMod to restore it.
thanks euclid. I might try this later but i can't figure out itsmagic. I installed the clockworkmod recovery with acer recovery installer. Can i just boot into recovery after that and have itsmagic work?
edit: i got its magic running then did the steps in the post minus the recovery. when it was done the device rebooted and got stuck on the acer logo. after that i booted into clockwork and installed the 3.1 update.zip and now my tablet is working fine again.

[TUT] Flashing your first A500 custom ROM

Well, flashing a custom ROM on our beloved Iconias became quite easy now thanks to developers on xda. Most of you are quite familiar with the procedure but there are still people that ask basic things all over the ROM developement threads. This is just a beginner's guide, an attempt to collect all the procedures and tools in one thread. Nothing of this is my work and I would like to say THANK YOU to sc2k, thor2002ro, Euclid's Brother, Chainfire, monki-magic, drellisdee, ezterry, Skrilax_CZ, gersma and all A500 developers for making this possible.
You will need the following: external SD card, root rights, unlocked bootloader (if you're on stock ICS), custom recovery and a custom ROM of your choice.
Well lets start by placing an SD card in the SD card expansion slot. Its file system should be FAT32!
*This is optional: To be sure it is recognized later in CWM, format it first with SD Formatter - a tool that can be downloaded from here. Use your home computer / notebook with a card reader for this procedure. Alternatively you can do this using an ANDROID phone.
1.ROOT
Root for Honeycomb 3.0.1 by monki-magic
original thread by Slowie911 here
1. Make sure usb debugging is turned on and unknown sources is selected in Applications settings.
2. Have a micro sd card inserted and turn the tablet on portrait mode and lock it with the switch to fix it in portrait.
3. Download and execute the attached apk. (i had to download from my comp and transfer to the tablet for it to work).
4. Once the apk is installed run the root procedure within the app which was installed
5. Wait and you will receive full root access.
Download Gingerbreak 1.20
Root for Honeycomb 3.1 by sc2k thread here
1. Goto Settings->Applications and enable "Unkown sources"
2. Download the attached APK file
3. Copy the file to your Iconia
4. Install the APK & start the tool
5. Click "root"
6. Enjoy
/IconiaRoot should work on both 3.0.x and 3.1/
Download Iconiaroot 1.3
Root for Honeycomb 3.2.x OTA
Unfortunately there's no dedicated rooting app yet developed for HC3.2. It also comes with a new bootloader. In order to get root you need to revert to an older version of Honeycomb first where Iconiaroot works. How to do that is explained in details in this thread
UPDATE: if you're on OTA HC 3.2.x then you can just update to ICS and use the method for rooting ICS - links posted below
Root for ICS 4.x.x OTA
Stock ICS Leak One-Click Root Tool by blackthund3r
or
Full root for A500 ICS 4.0.3 - Simple method, posted by ZeroNull
2. Bootloader
Since there are many new ICS custom ROMs and custom recoveries, please read in their dedicated threads if they require ICS bootloader. Some of the ROMs can recognize the version of your bootloader and load the proper boot.img during boot. In general - if you're on Honeycomb - you have HC bootloader. If you've updated OTA to ICS, then you have stock ICS bootloader, that is unusable for flashing custom ROMs and therefore you need the unlocked bootloader. A guide on how to install it read here - thanks civato. This thread links to a nice little piece of software (option 1) by gersma that can automatically do all the job for you - install ICS unlocked bootloader and custom recovery. Read and download here - AfterOTA by gersma
3.Custom recovery
original thread with clockworkmod recovery by thor2002ro here
1. Open Market app with your tablet and search for Acer Recovery Installer.
Acer recovery installer
2. Install it and then open it. It has ClockworkMod Recovery by thor2002ro rev1.3.4 built-in.
3. Select "ClockworkMod Recovery rev.1.3.4 by thor2002ro". Tap on install Recovery Image. A popup offering to backup current recovery image will appear. Surely, buckup! Thus you can restore your original recovery image in case of need. Then CWM will be installed. Once it is installed you can remove Acer Recovery Installer tool from your system if you want.
thor2002ro updated CWM to 1.7.3. You can download the zip from tegraowners.com. Later versions of his recovery does not meet GPL because of the "mini" kernel of his - sources not being released. It supports flashing both from internal memory and the external SD card. In order to update your CWM to this latest version, place the downloaded ZIP on your external sd card and update from your CWM by choosing install zip from sd card. Alternatively you can extract the recovery.img from the zip, place it on your external sd card and install it through Acer Recovery Installer by choosing Custom or Stock recovery.img from micro sdcard.
GPL compliant recoveries
RA Revamped for Iconia
TeamWin Recovery Project (twrp) - needs ICS bootloader
A500 Public Recovery
Since the creation of AfterOTA by gersma, you can use his software to install both the bootloader and CWM before flashing the ROM. Get it HERE
4. Flashing custom ROM
Download the ROM of your choice which should be a zip file. Place the zip on your EXTERNAL SD card. Power off your device. Now hold volume down and power buttons together until you see text appearing on the top left corner of the screen - you can release both buttons now. Wait until CWM loads. Volume keys (Up and Down) are used to navigate the CWM menu. Power button is uded as "Enter" i.e. to proceed with your selection. Before going on to install your ROM do a full backup of your system first. Navigate to "backup and restore" and then select Full Backup. Wait untill the operation completes.
Now do the following:
Wipe menu:
- wipe data/factory reset -> navigate to "Yes - delete all user data"
this should format you data partition and cache partition (dalvik cache is gone as well)
Mounts and storage menu
- Format System
this should format your system partition
The above commands are presented in thor's CWM. There are slightly different menus and sub-menus in the other custom recoveries but if you dig a little you'll find that they do the same things and you'll get the idea of what you're doing.
Now you're ready to install your ROM. Get back to the main CWM menu and select
- Install zip from sdcard -> choose zip from sdcard.
Navigate to your zip on the SD card and install it - choose "Yes" again to install. Wait untill installation is complete, return to the main CWM menu and choose "reboot system now".
You're done, enjoy your first custom ROM. Take time for its initial configuration.
5. Flashing custom KERNEL
Flashing custom kernel is as same as custom ROM. You place the zip (Kernels come in zip files as well) on your external SD card and:
- Install zip from sdcard -> choose zip from sdcard.
It is recommended before flashing a new kernel to wipe cache partition and dalvik cache. And of course first you flash the ROM and then the desired Kernel
6. UNBRICKING by flashing a stock ROM
thanks to vache we have full packages shared in his topic
vache said:
Once the desired file downloaded, you have to use Acer Update Decryter by thor2002ro to decrypt them.
After decrypting the file, you have to extract the update.zip from it, put it on an external SDCard (does not work on internal memory) and boot your tablet with Vol- & Power. The update will launch automatically.

p.s. Feel free to add stuff to this tutorial - video, pistures or anything you find useful or to correct me if I've made a mistake.
This is fantastic. Thank you. I have had my iconia for a month now and been looking at flashing a custom rom but kept backing out. Just a couple of questions for clarification:
(1). Does wiping data erase the internal sd?
(2). If by some stroke of bad luck a flash is unsuccessful and a boot loop or similar occurs, am I right in my understanding that you can just go straight back into recovery and re-flash?
(3). What are the chances of bricking the tablet?
Sorry for noon questions, please just wanna certain because my gf bought me this tablet under the condition I don't do anything risky like on my x10 that I flash almost daily haha

1. No, it doesn't.
2. Yes. You can do that. There's another option in mounts and storage -> format system - that will format even your system partition and leave your device bare with no ROM files on it. That would be a really clean install I guess
EDIT: I just saw that system is formatted during ROM installation. So no need to do that
3. Always read first what option you've selected and be sure you understand what it does. If you have CWM successfully installed, you have a powerfull tool to restore reflash, wipe, format etc. I've flashed my HD2 hundreds of times and now my Iconia is on the run Never ever had a boot failiure.

VERY good information here. Thank you very much for taking the time.
I've flashed ROMS on my last two "chinatabs" but haven't gotten into it with my A500 yet. (To be frank, I'm still thrilled with the prospect of OTA updates from a manufacturer after my last experiences.)
It looks like the process is very similar to my Rena3 tablet.

Thank you, that lays it out all nice and precise for us all. Like strider_mt2k, I have been holdng off on the custom ROMs, because my first tablet was a Gtab, and while it became a pretty awesome tablet, it had to be flashed with a custom ROM to be really usable. The OTA thing was holding me back. But I think that I may try to flash the thing this weekend if I get the chance.
Thanks. Glad it could be of use.
nice tutorial dude! thanks!!
could you please make another tutorial to return back to stock?
specially to return back to stock te kernel.
thanks!!!
As mentioned, best case is if you've backed up your device before flashing any ROM or Kernel. Thus you can restore to your country specific version.
Otherwise its pretty simple - its just like flashing any other ROM following the steps described.

Unfortunately I can not tell you for sure. I haven't tried all of the custom ROMs but in most cases - no you won't be able. I've tried Tabooney, Honeyvillain, Virtuous Picasso, Virtuous Galaxy. ROM developers usually update their ROMs to the latest base available. I think it depends on many things - base, kernel, stock apps removed etc.
Maybe someone who have succeeded with custom ROM updating would share his experience.
Can anyone tell me if there is a version of ROM manager that supports the version of CWM that there is for the Iconia. I would love to be able to simplify my ability to backup my ROM's before flashing.

You can install a clockworkmod for Iconia no matter of the version of ROM manager. But it is much much easier to use Acer Recovery Installer. I recommend you using it instead of playing with recovery img files. It is a one time procedure after all
Anyway - here's what you need to do if you don't want to use Acer recovery installer, or you don't want to use ADB:
http://www.addictivetips.com/mobile/how-to-install-clockworkmod-recovery-3-using-rom-manager/
instead of CWM 3.x you will need to get CWM from thor2002ro In this guide you substitute the recovery that ROM Manager is about to flash with thor's CWM. I haven't tried this method myself but it should work.
With Acer Recovery Installer you can flash custom recovery as well. As long as you have it in IMG format you can be flashed from within the app - "install custom or stock recovery image from sd card".
great thread.
thanks!!!
Great Tutorial!!!
Just a couple of doubts:
First question: Backup files.
3. Flashing custom ROM
"...Before going on to install your ROM do a full backup of your system first. Navigate to "backup and restore" and then select Full Backup. Wait untill the operation completes. "
Where do the backup files go in the system? On internal or external SD card? Is it an *.img file extension?
Should i move it to my computer to keep it save, or just leave it where ever they are?
Second question: Kernel.
4. Flashing custom KERNEL
"Flashing custom kernel is as same as custom ROM. You place the zip (Kernels come in zip files as well) on your external SD card and:
- Install zip from sdcard -> choose zip from sdcard.
It is recommended before flashing a new kernel to wipe cache partition and dalvik cache. And of course first you flash the ROM and then the desired Kernel"
I am on Stock 3.1 ROM with original Kernel, if i want to try Virtuos Picasso, do i have to flash a new Kernel? And if yes, shouldn't i do it before flashing the ROM? Or just flash the ROM and then the Kernel? What happens if i just flash the Rom and use the stock kernel?
Thank you..
Your backup goes to your external SD card in a folder named clockworkmod\backup\2011-XX-XX.HH.MM.SS
As you can guess the name of the backup corresponds to the time it is created. This backup can be used to restore your system through CWM in case of need.
CWM does not backup /data/media folder. Additionally: you should also delete .android_secure.img from your backup set or a full restore will fail before it restores flexrom.
The last is an issue described by Euclid's brother:

No, of course! Your custom ROM (Virtuous Picasso in your example) and any ROM comes with its Kernel. Its up to you to decide wheather to change it or not after that by flashing another Kernel. Follow every Kernel developer's notes for ROM compatibility. So, that answers the last part of your question - you cannot flash Virtuous Picasso and still think you're on stock kernel

Oh, i see...i thought that the flashing ROM procedure of a custom ROM, would just flash the ROM and not the Kernel...so in this case i just have to choose the ROM that i want to flash and do not have to pay attention about the Kernel compatibility...unless i flash a Kernel only. Right?
Thank you very much!!
That is correct

CWM 5.5.0.4 and 5.8.31

what is the difference between CWM 5.5.0.4 and 5.8.3.1. Why ROM manager installed CWM 5.8.3.1 in Galaxy Tab P7500 while taking backup, though CWM 5.5.04 was already installed using ODIN I.85. Is it necessary to re install CWM 5.5.0.4. If so, how to re install CWM 5.5.0.4. My galaxy TAB P7500 is running on stock ICS 4.04.
Only a few changes are made(you can't even say where)from 5.5.0.4 to 5.8.3.1...
The ROMmanager must make sure that the CWM on your device matches with the version of the APP,but upgrading does no harm i.e. it's no need to reinstall CWM...
Beware!don't go into CWM if you are on the stock ICS because it has the rolling screen issue,flash all you need with ROMmanager,don't install CWM touch when you are using stock ICS(it'll be a waste of time,mony,etc)
If you want to get out of CWM(5.5.0.4) after flashing but get confused with the rolling screen just do thisress vol down and then press the power button twice...the tab restarts with all the changes you've made...
And finally:feel free to ask questions,XDA in always here to help you!

I'm using CWM 5.5.0.4 here with stock ICS. No problems at all.
5.5.0.4 is the version recommended to prevent rolling recovery.
I also followed pershoot's advice in the 2.6.36.4 thread. I did get the rolling recovery even with 5.5.0.4.
I am on stock US ICS and odined the following:
(1) US ICS 4.0.4 BL variant
(2) Recommended recovery (CWM non touch 6.0.1.2)
Now I have no flicker in the recovery or the ROM like I had experienced in the past. However, I'm rather way of CWM 6.0.1.2 because I used the previous non-touch (6.0.1.1 I think) and wasn't able to restore a Nandroid...it just hung on me. Where did you get the 5.5.0.4 that worked with stock ICS ROM/BL Jack?
Hi dj.
Can't remember now where I got 5504, read so many guides.
I have it in my drop box.
I'll post the link for it shortly.

You're welcome.
Good luck.
Thank you for your nice advice and assurance. Sir I have another question/doubt. Please clarify
I am having P7500 in India. I flashed Italian stock rom 4.04 using ODIN. Later rooted the Tab using CWM 5.5.4 method. subsequently I installed ROM Manager. I did back up. It appears that CWM version was changed by ROM manager. Now I want to flash Indian stock rom 4.04 recently released and also rooting. Please suggest a mode.
Download the stock IN firmware from Sammobile and flash in Odin with PDA with your tablet in download mode. You will lose everything on your internal storage so if you want to keep your backups make sure to move them off the tablet before you flash.
You'll find lots of guides in the Q&A and Dev sections that will provide root methods for your 4.0.4 stock firmware. Or, you can skip all of this and just flash a rooted ICS ROM with a full wipe to save yourself the steps. It's really up to you.
Thank you Sir for your valuable advice.
Please clarify, If I flash INU stock ROM 4.04 on ITLY stock ROM 4.04, using ODIN, will it wipe out applications data also?
Earlier When I flashed ITLY stock ROM 4.04 on my original stock ROM 3.2 INU on my galaxy tab p7500 using ODIN, it did not wipe out any data from internal storage and all the applications were automatically installed after reboot..
It may, it may not...it depends on whether or not you boot up after the flash without issues. If you get stuck on the Samsung logo or a boot loop, you will need to boot into stock Android recovery and do a factory reset, that would format your /data partition and result in loss of apps etc.
That Thanks button works well if I have helped you makes me look like less of a noob! Good luck to you

I recommend doing a full wipe with CWM recovery before flashing with ODIN. Doing that avoids having to do a full wipe with Stock recovery which wipes the internal. Wiping before flash should avoids formatted internal. Would others confirm, this is what I have noticed on my tab.

[Q] Custom Recovery Lost after Flashing cm-11-20141028-NIGHTLY-mb52x.zip

Hi all, I met a problem after flashing cm-11-20141028-NIGHTLY-mb52x.zip.
I cannot enter Custom Recovery (TWRP) any more. Other functions are OK, but I cannot upgrade to new ROM now.
Is there a simple way to restore Custom recovery in CM11?
Otherwise, I will have to use the method: "flashing stcok ROM (Android 2.3) -> root -> 2nd Init -> flashing Custom recovery", to restore it.
Thanks in advance.

Hi jh20, thanks for the information.
I checked the post you provided. However, my problem is that I cannot enter the Custom Recovery anymore, let alone flashing another ROM.

perhaps i should explained a little more. these are based on memory as i haven't done these a while now.
cwm recovery had been permanently removed from cm11, and you can only flash cm10 and not anything earlier (cm7 or cm9) with cm11's twrp because of ext4 partition. so as long as you can still get into twrp, you can flash cm10 which still has both twrp "and" cwm recovery. cm10's cwm recovery allows you to repartition it back to ext3 and hence allows you to flash cm7.
i did a little google on how to revert from cm10, and here are the hits:

if you need more just read the other posts. hope they help.
Thanks a lot, jh20.
I think I made a mistake in the post, that I was not use CWM recovery in CM11, it is TWRP recovery instead. I've update my post to reflect this.
So the problem is that I cannot enter TWRP recovery any more, and cannot flash another ROM or anything via TWRP recovery.
Is there a simple way to restore TWRP recovery, otherwise I have to start from scratch by flashing stock ROM, ...
I'm not trying to go back to CM7.2.

Sorry, not with my knowledge. So unless some experts/developers here have any ideas, you might have to start from scratch.
