I know this has been asked but i am new to Android. This is my first device i am tring to root and cannot root i have tried using Iconia root and Gingerbreak. Both do not work on my device. I don't want to take my device (Acer Iconia A500) to a older android software. and was wondering if somebody can point me in a direction of a valid way to root HC 3.2, i would be in your dept.
Again i am sorry for making this tread i know it has been asked and asked and asked but there is alot of bogus things and/or solutions for older software for my device.
Unfortunately, to root 3.2 due to the new acer bootloader, you first have to rollback to an older version of HC.
http://forum.xda-developers.com/showthread.php?t=1276227
Not that it can be a little bit unstable, but most folks were able to work with it, and have success.
After you get your root, you can flash most of the 3.2 roms in the dev forum for the 500.
It seriously is not as bad as it sounds to roll back to the 3.01 software, root, and then install your custom rom. once you get the files downloaded, you'll be good to go in less than 30 minutes (probably less than 15 if everything goes flawlessly).
Yea I was surprised at how quick and painless the process was, and some of the custom ROMS are far better than the Acer OTA one. The rollback to 3.01 I believe is the simplest but I think I read before of someone rooting 3.2 without rolling back. It was a very complicated procedure though and I wouldn't recommend it.
yea
This is what i feared is i had to go back to a older system, but i understand and i may do it. All i need to know is does going back to the old software delete all my files on here and if so whats the best backup program to use? by files i mean apps, music, and settings.

Anything on the sd card is safe (if you keep your music and fotos there). As for apps, the Market always remembers paid apps, and the newer market usually remembers most of the free apps you downloaded (I believe the apps are synched to google), so when you flash a new rom, it usually (in my experience) starts to download them all once you login to your account on first boot.
Out of luck on settings though. Installing a different rom will wipe away all user data. App settings, etc. You can use a backup app like Titanium backup, and backup like game data and app settings, then restore them after flashing a new rom, but really, I feel it's better to get a fresh start on a new rom

If you are worried about backing up your apps, there are free apps in the market that will create backup files of your APK's. As for music and files, i find that flashing a new ROM they are still there, but just to be safe you can transfer them to a usb stick or something if you are worried about losing them. As for settings in the apps, you might be out of luck. I don't know a way of keeping them, but at the same time I never really cared to.

I used method #2 in this link and it worked great for me. Then installed one of the rooted 3.2 roms in the development section and was up and running in no time. No data was deleted and all my apps were ready to go. When you first boot after the downgrade you will get a bunch of force closes, don't worry that is normal. Just follow the directions, install and run iconiaroot1.3, then install the cwm recovery through the acer recovery installer, then install the rooted 3.2 rom and when you boot up everything will be working correctly and you will be rooted. Here is the link:
http://forum.xda-developers.com/showthread.php?t=1276227
Also, I downloaded and installed the iconiaroot 1.3 and the acer recovery installer before downgrading so everything was ready to go. After you install and enter the cwm recovery, only wipe dalvik and cache before installing the 3.2 rom. If you wipe data you will loose all of your data. Took me about 10 minutes for the whole process and I didn't loose any data or have to re-install any apps.
tring but not success
i downloaded the zip file and installed the files in the zip file to my external cd card......then when i try to reboot using the power+vol-down keys it starts to load files then the android emblem comes up loads to 3/4 the the bar goes away and the android stays and now has a caution symbol in the middle and then the tab boots normal with all normal software......and help as to why i cannot flash the old software
Sounds like the file got corrupted. If you downloaded from a PC, try downloading it again. If you downloaded from the tab, try doing it from a PC and then transferring it to the tab.
Some apps not working after updated to 4.2, so I'm considering back to 4.1.2.
Though I never done this before since the day I get Nexus 7,
I think use Wug's Nexus Root Toolkit should get it done.
But just for sure:
1. Do I need to unlock/root to flash factory 4.1.2 image? (I think it is not but not so sure)
2. Directory structure seems different from 4.1.2, is it OK just using Toolkit to backup/restore settings?
(Sorry for my English if anything looks impolite)
1) unlock bootloader yes; root no, as you're going to overwrite the system anyways.
Also I'd suggest not using a toolkit, just download the factory image off google's page and run the "flash-all.bat"
2) Use Titanium Backup to backup all app data, wipe after flashing 4.1.2 and then restore apps + data with Titanium again
I just downgraded this morning. All your data will be wiped .. ALL YOUR DATA ... meaning, after I got back to 4.1.2 I was having 13GB of free space on the tablet (out of 13 possible) .
So, if you HAVE a nandroid from the 4.1.2 days, save it to your computer (along with all your files).
If you don't have a 4.1.2 nandroid, at least create now a backup repository with whatever tool you prefer and then save the respective files to PC.
Then, flash the factory image for 4.1.2.
Then copy all your files back to the internal memory, install the backup tool and restore your apps.
The reason behind this is that the update from 4.1.2 to 4.2 has some scripts that are porting the original /data and /sdcard mounts to the new structure used in 4.2
When downgrading, you no longer have scripts to do that for you so the newly installed 4.1.2 will not recognize anything so it will bootloop like crazy (I tried first to restore just the /system ... but all the other data was already affected by the update so was no longer usable).
My thoughts:
If you got the ota, and things messed up, try flashing the 4.2 factory image. That seemed to help me. If you're not rooted already, I would recommend becoming familiar with the adb backup command to backup apps before doing anything else. You have to unlock the boot loader to downgrade or flash the factory 4.2 image, and this will wipe the device.
Once you update either way, definitely take the time to root. You can then use adb restore or titanium backup to restore from the adb backup you made before unlocking.
Just be aware that adb backup doesn't seem to backup all apps, and that titanium backup isn't exactly fast parsing through a big adb backup file.

Assumed you are referring to downgrade from 4.2.1 to 4.1.2 and rooted to run TB, so the basic stock rom is up & running otherwise, correct?
Let's try Plan B instead - go into (Custom) Recovery and wipe dalvik cache first, then reboot. Give it a few minutes to settle and try to do your TB restore WITHOUT data, and see if it works. The /SD and/or /SD/0 directory structures are setup differently on the N7 and trying to retore with your custom settings will just make it more difficult & complicated. If this works, you can then try to selectively restore one or more with data and hopefully without going into endless bootloop again.
Plan C - go to Play Store, then Settings and "All" - you should see all of your Apps and what's installed, etc. - and install from there, it's semi-manual but it works for me 99.8% of the time when it would otherwise freeze within TB, especially true when switching custom Rom & kernels.
I usually manually copy & move back items such as documents, pictures & mp3's, etc. from standalone/usb backup drives or cloud storage back into the device once everything else are up & running properly.
Let us know if this helps & working for you or not.
Thankss !

Thanks for your help , but I think the problem was that there were apps in the backup only compatible with the custom ROM I had and android 4.2.1 xD
I restored the apps one by one , but I think if I deleted the extra custom rom apps , the process would have finished without any problems
Hi fellow people,
i'm a noob just made my xda account like 5 mins ago. I've been trying to search for my problem but I haven't really a found a direct answer. So yesterday I just got my Samsung Galaxy nexus update to 4.2.1. I was really excited until I started having the battery issues, screen lock issues, and overheating problem. I really don't like 4.2.1 and want to downgrade my version back 4.1.2. My carrier is the Mobicility (Canadian). I did not do anything previously with this phone such as rooting it, doing all the funky stuff that will void my warranty. I heard about flashing some google images to get back 4.1.2 but I'm not sure if I need to root or how to like do it through the gnex toolkit that mskip made. As well what if the difference between yakju and maguro? I heard if you flash the wrong image it will brick your phone or something like that. If there is a method without having to root it and lose all my contacts, then I would prefer that a lot.
Thanks,

You dont have to root but you need to UNLOCK the bootloader which will obviously erase all your data(and VOID your warranty). you can find the factory image here https://developers.google.com/android/nexus/images . just flash the appropriate image and you should be as good to go.

Asus Nexus 7 is not the same thing as a Samsung Galaxy Nexus.
Ignore mmystere68's remarks.
Hey everyone, I'm new to android game, I've been cracking iPhones since 1st gen, decided to challenge myself. I have an S4, rooted, but no CWM installed. I want to save the recovery so if any issues ever occur, I can just flash it and have it covered under warranty, and also to be ble to return to stock wen I sell the phone.
Is there a tool i can use to make a nandroid backup? On my Nexus 7, There is an all-in-one tool and I can make a nandroid straight from my PC. Is there anything similar for the s4? If not, how to I make a nandroid backup? thank you everyone for your help, I appreciate it
Odin back to stock if you ever need to.

I'm not entirely sure it's possible to do a nandroid backup without first having a custom recovery. However, it is "always" possible to use the Odin method to return to stock (including stock recovery). Personally, I installed TWRP and immediately did a full nandroid (including system, boot, cache, etc...) and I've frequently found myself restoring pieces of it as I manage to screw up different things. I did return my recovery back to stock once by using the "dd" method to flash the stock recovery.img onto the correct emmc block. There's instructions how to do this exactly on the TWRP homepage (make sure you get the correct phone - block numbers are different for different devices) - but instead of re-flashing TWRP, I pulled the recovery.img from the giant Odin image available here on XDA.
It may also be possible to use "dd" to pull a copy of your existing recovery image as well, but I've never tried it.

Thank you! I'll be installing TWRP today, what is Odin if I can ask? I've never heard of any of it from Nexus 7.
Also, If i do a titanium backup, can I easily restore apps with setting and save games while I'm running CM10.1?

You better find out what odin is because it's the only way you'll be installing twrp. And don't count on tibu restoring all your apps seamlessly. Never reinstall system apps.

I installed TWRP through GooManager. I looked up ODIN and got general info, hopefully I won't get stuck, but I'm sure I'll find my way around. Thank you so much for your help! I figured that sys apps will just be for stock, but i have a MC4 save that i don't want to lose ::cyclops: it looks like it's CM10.1 time for me!

Here's the thread that explains how to return to stock using Odin. Be prepared for a large download.
http://forum.xda-developers.com/showthread.php?t=2261573
In short, "Odin Mode" is the download mode that's built-in to just about every modern Samsung device, beginning as far back as the Captivate, afaik. Each device has a button combination to enter "download mode" or "odin mode". This special mode sometimes requires specific drivers to connect to your PC. Flashing stock firmware using this method is common, but with an unlocked bootloader, it could be used to flash about anything. It's like a secondary recovery in a sense. It's harder to destroy download mode, but still possible if you mess up the bootloader somehow.
For our device the easiest methods to get to download mode are:
- Hold down the power button until the device force-resets itself. The moment the device turns black, release the power button and begin holding down the Vol-Down button. The device with vibrate once as usual, but then you'll see a screen that you've never seen before (begins with "Warning!!").
- Using any shell, such as ADB Shell or a terminal emulator, give the command "reboot download". This may require root privileges, I'm not sure.
- There's apps for this - haven't tried them yet.
As for Titanium backup - I love this program and have purchased Pro (totally worth it). As others have said, it's a bad idea to backup/restore System apps. Only do so with extreme caution. It is possible to restore only the data from system apps, but again do so with caution.
While Google does its own job at re-installing apps after a factory reset (if you allow it to), it usually doesn't backup data for each app. I have a couple authenticator apps that I backup this way, and it works great for this. I've also managed to keep my copy of Angry Birds Samsung Edition from my Infuse. Other applications that have since disappeared from Google Play are still backed up and get migrated to each new device I purchase.
And for that matter, with almost every User application, you can easily back it up (with data) and restore it on a completely different ROM. When changing major android versions, you sometimes will find apps force-closing on you, requiring that you wipe their data... but I haven't had that problem in a long time.
You'll see some other things that you can backup, like SMS, Access Points, Bluetooth Pairings, etc. .... I recommend only restoring these with caution - especially cross-ROM or cross-device.
Okay, I'm done being long-winded. Good luck, have fun.
Good write up

Thank you so much!
Just got a GTab 2 7.0 a few days ago. A P3113, so only 8GB of storage, about half of which is the ROM and crap apps. I've rooted before (had a KF 1st gen when it came out), and just wondering about a few things with the GTab:
Right now, I don't mind the stock ROM so much. There are problem things that would be "nice to have", but right now, would like to generally stay as "stock" as possible. That being said, I'd still like to "de-crap" the ROM to free up some storage space, and I assume that might lead to it running a bit better, since so much seems to just pop-in while running other apps. So:
I know I need to root first, so my first question - how reliable is that? I'm on a Mac, but have access to a netbook running Win7, so could run Odin to "get things done". I'd hate to brick the thing, still having 51 weeks of warranty left. (I also understand that I might want to install something else to keep the flash count from showing it's been flashed).
Once root'ed, is it better to use one of the "de-crapped" ROMs floating around? And if so, which seems "best" (yeah, I know the moderators hate the "which is best" - I'm looking for stock - and STABLE)
Or, is it better to eliminate the apps myself? (Not sure if this is a wholesale "rm" to remove certain apps from a terminal app, using adb, or if they have some uninstallers embedded somewhere, or...) - so better to use one of the ROMs floating around?
Is the GTab 2 "stable", so even if you trash a ROM, you can still get into the ROM manager to restore a previously working, or stock, ROM?
I'll probably come up with a couple more questions, especially depending on the replies... TIA
Hi..
I can answer some of your questions. I hope that helps!
1- Rooting is easy and reliable. you may use "CF-Auto-Root" tool (search for it in XDA forum).
But you need to remember that rooting and custom ROMs void your warranty.
2- If you just need to free some storage space, you may use an app such as "Clean Master" to uninstall system apps and get rid of temp and junk files.
3- If you opt to use a custom ROM make sure it is very well supported and maintained.

Thanks - but prior to using Clean Master I assume I better either get a stock image to reload, or use CWM so I can make a backup of the ROM before messing something up?

Taking a backup is always good thing to do. I suggest you try clean master to know how it works and what does it do.

Thanks - I plan to use Clean Master. Allows me to be selective about what I remove/move, instead of getting a ROM from someone and they removed the ONE THING I really wanted.
Ok, got it rooted and CWM installed.
HOWEVER, when I boot into CWM, I DON'T see an option to backup my ROM (I've used TWRP before on my KF, so the menu is different).
What I've got on my screen in CWM:
Android system recover <3e>
Volume up/down to move highlight;
power button to select.
reboot system now
apply update from ADB
apply update from external storage
wipe data/factory reset
wipe cache partition
apply update from cache
That's it. Where's the option to do a ROM backup? Oh, used file P3113_SAMSUNG_RECOVERY_SUPERSU-0.96_BUSYBOX-1.20.2.tar.md5.zip Had CWM and Root all in one. I do have GT-P3113_ClockworkMod-Recovery_6.0.1.0.tar as well. Should I just go through procedure again to flash this CWM? Will it still retain SU?
nandroid backup ok to use? Seems it's just a wrapper for a backup script...
Ok - I'll reply to myself.
I don't know what was wrong with the CWM I installed via the aforementioned file (P3113_SAMSUNG_RECOVERY_SUPERSU-0.96_BUSYBOX-1.20.2.tar.md5.zip), but I went to the CWM site, D/L'ed the latest touch enabled CWM for the P3113 (6.0.2.3, I believe), and installed it over the existing recovery image on the device (I had to create my own .tar.md5 - easy with *nix).
Anyway, I now have access to the backup options by scrolling down. The image from P3113_SAMSUNG_RECOVERY_SUPERSU-0.96_BUSYBOX-1.20.2.tar.md5.zip, simply wouldn't scroll beyond what I listed earlier. Now can scroll down, make backups, etc.
Haven't tried yet to re-install the image I made with nandroid - I'm a bit leery of that - so I'll just get the stock 4.1.1 ROM from sammobile, and keep it around....

That's exactly what I did today, grabbed the stock image for a backup, rooted with Odin and CWM then flashed a CM based 4.3 ROM. Piece of cake.
Hello there!
I rooted my Nexus 6P, as I've done with every Android I've owned since my Nexus One, as soon as it arrived.
However, I really like NFC payments (we don't have Google Pay in Spain, but there are several banks that offer that option) and when the January security update came out, I un-rooted flashing everything.
After that, two of the bank apps worked, but one of them still refuses to do so.
In addition, I've been suffering from very, very, disappointing battery life: no more than 2 hours SOT and having to recharge twice a day.
So, I've decided to start from scratch, using the latest image that came out today.
But I have several questions and I'd be very grateful if somebody could answer them:
- First, and most important. I've been using Titanium Backup since the dawn of times in order to preserve my settings. I've a couple hundreds apps installed and making each of them behave as I like is a nightmare. Is there any rootless backup solution? I know Google backs up everything, but I don't know if every setting will be restored as I want.
- Second... actually there are no more questions, I can look for how-tos on how to flash the image, go back to default recovery...
Thanks in advance.

In titanium backup you can have it export your backup to an update.zip that you can install via twrp. Having twrp as your recovery does not break Android Pay, as does root, xposed, etc..
edit: yes this applies to now, after google made changes to the server side that broke the root work-around

I've been restoring what I can from my Google account for three phones now and, while it's best it's been on a Nexus, you still won't get app settings and full data restored, so Titanium is needed for that. I've never tested the zip export the first reply suggested, but that's an interesting idea. As for getting back to a stock install, there's a very handy guide at http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928 and it covers all scenarios thoroughly. The command line is really the fastest and easiest, as the guide includes code you can just copy and paste. I don't think it's been updated regarding root, because systemless as a way to preserve AP was just stopped by Google.

I have once tested the update option but what I got is only apps and not data. I'm pretty sure I chose app+data while doing the update zip.. Beware of such things happening.

Thanks a lot for your answers.
I've been reading and it seems that, without root, TiBa's update.zip file won't restore app data.
There seems to be another app, Helium, that does a neat trick. You have to connect your phone to your PC, and Helium talks to the PC so that it uses adb to create or restore the backup. No root needed. I think I'm going to take my chances with that.
ultyrunner, that's the guide I was planning on using in order to go back to stock... thanks again, you saved me the search
