So I have a I-9020A with at&t. I have rooted followed by flashing -su and roms instructions using instructions on the net. But after following that process and then going backwards (flashing stock w/ no root locking bootloader) I have realized after that I have more questions.
So first: Unlocking the Bootloader erases the phone. Unlocking the bootloader is needed to flash CWM and SU. I have read many many things about NANDROID, how is NANDROID different from CWM?
So I guess my next question is: How does one remove SU? In the process of rooting and flashing CWM and ROMs I make a backup prior to going to deep... that Backup will have SU, I have unrooted, but SU is still on the phone and I cannot seem to remove it.
Another question is: where are the data files on the phone for apps like Plants vs Zombies? I would like to move them off my phone prior to root, though I'm not sure if that is possible (is it?).
The last question is: If I wanted to muck around with ICS and the source code, is it as simple as flashing the source as explained on the google site? because they make it sound rather easy.
Thanks for any and all help,

When I power my phone off and press Vol up and power on then go to recovery I get an Android w/ a triangle with an exclamation and cant do anything at that point.
So I guess my next question is: How does one backup a stock rom (like you would using CMW) without rooting? or is there not a way and I should just except that when I root for the first time I should expect to loose everything and take off things like pics ect before hand.

Sounds like you should have read more.
When you open the bootloader (the lock) it will wipe your personal data off the phone (not SD storage). This just means you get it as if you just bought it from the store. There is no way around it but happens only once and you'll never have to do it again. Unless you lock it back
Once the bootloader is unlocked you can now flash a custom recovery such as CWM which will let you manage and back up your phone with whatever ROM you want/have.
Once recovery is on your device you also have to root the phone. For this you'll need a zip flashable file with the superuser apk and SU binary files. Flash it in recovery and you should be good to go.
The last step is to install a ROM of your choice. You can just run what the phone has and it will work fine and even take updates without a problem. However, every time you want to flash something you'll need to flash CWM again because the stock image flashes the default recovery on reboot. There is a file you can delete to prevent this from happening. I forgot the path so look around. However, I would recommend you flash a stock ROM which already comes loaded with good stuff and all other things are done for you Just stop by the development section and pick a ROM you like.
Naroid is just a backup.
Oh, and BTW, mocking around with ICS... I would leave that for later. First get your head around basic flashing/rooting stuff. Changing the source code requires knowledge of code and even phone hardware. I'm guessing it's not for you just yet

i was going to write something similar. toonhead85 you should do a bit more research and reading before you start hacking on your phone. youve hearts in the right place, but youre not quite ready just yet. at least take small steps at first
A little more clarification or nandroid backups:
Nandroid is a specific type of backup of the phone's system files. I think that includes system rom and radio. I not sure if any data is included in the backup. You should make a nandroid backup of the stock rom bbefore you flash any custom roms. If something goes wrong with a rom flash or if you want to restore to a previous stock or custom rom, you can restore from the backups you have made. You create these nandroid backups by booting into recovery and selecting the backup option (I think maybe named backup and restore). Backups are usually found on your SD card, but you can copy them to your computer to save additional copies.
If you want to also backup apps, get a good backup program from the market. Two that I have used are Titanium Backup for Root and MyBackups for Root. They can backup and restore apps and data as well as system data.
Thanks for all of the amazing replys. I do know that I am not at the point where I wanna muck around in the system to much as this is my one and only phone. But I would like to at some point.
But something I wanna know is this: If in flash CWM, can I use it without root? Say to make a backup of the stock rom before flashing SU? I only ask because I am currently at work and can't test the idea.
Another question is this: I know how to get to the stock recovery, but from what I read you use the VOL UP to get the "Menu". When I push any (hardware) button I get nothing and the image being displayed is an Android with a triangle and there is an exclimation point in it. Any thoughts?
a nandroid saves everything in your phone, just how it is at that moment. and when you restore it, your phone goes back to that very moment you made that nandroid backup. all your data remain. everything. its like you didnt do anything in between backing up and restoring

And CWM recovery.
You don't need root to backup but remember that when you reboot it will flash back to stock recovery (the triangle). You can simply repeat the adb command to flash CWM again.

So I could flash unlock my bootloader > flash CWM > Make a backup and save it to my computer then when i reboot my phone it would automatically reflash the stock recovery? and if this is correct, then all i would need to do is flash CWM to restore the saved backup?
So here's a question, is it the action of flashing SU that keeps the phone from removing CWM and reinstalling stock recovery?
You must rename the /system/etc/install-recovery.sh file or it will keep replacing the stock recovery. See this post, item 2.

I would like to root my sensation, but before, I want to backup my stock rom, so, in case of problems, I can go back.
But, if I have understood well, in order to perform a Nandroid backup (with ROM Manager, right?), I need to root my phone: it's completely absurd!
If I root my phone, which backup can I do? The stock Rom will gone away and the guarantee too!
Do I miss something?
Another question: I read about some problems with Rom Manager, which are the other methods to do a nandroid backup?
Thanks and sorry for the noob question, but I am a noob and this is my first android phone.
bye!
you will still have stock roms after you have rooted so this is what you have to make a backup from.
Have no issue with rom manager- dont know where u heard that from.
Dont know of any other method other than nandroid to backup rom etc
u can use titanium backup / my backup for apps etc

do a backup before you root
so sequence is (after CWM step is complete)
backup
root
backup (not 100% necessary but saves u having to reroot if u restore a pre root backup)
install custom rom (not necessary - u can stick with stock)
the guide u linked to is great - follow it step by step and u wont go wrong
and enjoy ur unrestricted device
That 'guide' tells you to root but you should only root if you want Stock ROM + Root
If you want a custom ROM (which automatically have root) then you don't need to root your Stock ROM
So you'd want to do this
-Revolutionary- S-OFF > Custom Recovery (but flash it through HBOOT) > Nandroid Backup
Then you have a backup of your stock ROM, unrooted.
You can now manually root your stock ROM if you like.
That 'guide' should really state that root is NOT obligatory if you don't want to stick with your stock ROM.
I've flashed lots and lots of ROMs and played about with my phone so much, but not once have I ever manually rooted.
And don't bother with ROM Manager, just flash the fixed recovery provided in that 'guide' through HBOOT and you should be fine.
All the recovery options, including Nandroid Backup/Restore can be accessed by loading up the bootloader and choosing 'recovery'. No need to do anything through ROM Manager
I want to confirm; we do need to make nandroid for every custom kernal, right? Cause if I remember correctly, if something goes wrong, you cant restore a nandroid that was made from a different kernal than you presently have installed. Correct or incorrect??

So, maybe what Im remembering is, you can't restore a 2.3.3 backup, if you have rom with 2.3.4 installed, for example.
Shouldn't you be able to access nandroid recovery on a stock out of the box sensation by turning off fastboot and holding volume down and power when turning it on?

Sorry should have specified my phone in the OP.
Best way is to do it manually. You can find all of the steps required here. The only difference is that you should be flashing the latest recovery from here and the latest superuser.zip file when flashing with recovery.
Note, unlocking bootloader will cause loss of EVERYTHING on the device that you have put on there (sdcard, apps, data partition, etc).

Do it this way. The one click is fine but using Android SDK and going through all that will help you in the long run. This way you know the process in case something goes wrong. It may be confusing at first but worth it. It will teach you a lot more than flashing a one click!
I learnt a lot from this and feel much more experienced and capable because of it. I know I will be able to solve any major issues using Android Debug Bridge (adb).
Okay then I am gonna try the manual way and gonna take out time for it. Now I just need to know what do I flash once I have unlocked bootloader and installed CWR?
I just want the stock google rom and receive OTA if nexus S continues to be supported by google.
You won't need to reinstall the ROM if you are currently on 4.0.4. The ROM stays there as-is. Feel free to do your wipes in recovery and reflash stock 4.0.4 through CWM if you must. You flash CWM to your phone and then superuser through CWM.
Steps:
Setup ADB/fastboot
Bootloader --> fastboot oem unlock --> agree
Bootloader --> fastboot flash recovery recovery.img --> this will give you CWM
Recovery --> flash superuser.zip and, if you must, wipe and reflash ICS (flash su AFTER this if done)
Reboot --> bingo
Also note, with stock ROMs it will replace your current recovery with stock recovery on each boot. If you want to keep CWM, delete /system/etc/flash-recovery.sh when you first boot. You'll have to reflash recovery afterward and it will stick.
Oh I was of the impression that unlocking bootloader wipes everything means it wipes the OS as well. That is nice if it's just data and not the OS, dont think I would reflash it if it's not needed.
Can you explain what you mean by will have to reflash recovery? I will have to do that even if I delete that file on first boot? And whats the drawback if I dont delete that file and stick with stock recovery?
As soon as you boot into stock android it will replace the recovery. So if that file is there on first boot, it will replace it while booting and you will be without CWM (stock instead). After first boot you can delete the file (you can reflash a ROM which has this deleted, or delete it yourself from a stock ROM, or even use adb or a recovery-based file manager to delete the file, then you won't have this problem at all) and it will no longer reflash stock recovery, but you would already have the stock one and need to flash CWM one more time to get it to stick. Easiest way is to just flash CWM and delete it within android imo, saves mounting commands and the such.
No downside really. If you need to flash something for one reason or another you'll just have to reflash CWM before you do so. Once rooted, ROM Manager can do this for you within android anyway.
I had already downloaded and installed the drivers from the one click root thread and my computer shows the android adb thing when I connect my phone with USB debugging.
But as you guys suggested I am gonna do the manual way. So do I just skip the installing driver on computer in the part 1 of this guide?

He has the i9023 to my knowledge. It is completely normal, though. Bootloader and recovery for i9020 and i9023 series are the same, this can be attributed to the issue with 4.0.3 recovery backlight not turning on.
If fastboot recognises your phone in the bootloader (the fastboot menu), your drivers are installed an working perfectly.
Finally got to the unlock bootloader screen, didnt do it just yet but now I know how to do it.
I must say the guide is a bit outdated, the software has changed quite a bit seems. The most frustrating part was that the fastboot file is actually in the platform tools folder instead of the tools folder which I didnt figure for a while. I will hold off rooting when I have a whole day off because once I lose everything I would be very anxious to get my phone back to normal which will take time.
Thanks for the help harbb, if I have any problem flashing recovery and superuser I will come back for more help.
And yes I have the LCD version i9023.
Btw the guide said the fastboot will be in the tools folder but the tools folder had a read me that "adb has moved to the platform tools folder" this is how I figured to go to that folder and thats where the fastboot file actually was.
Now it says I should put the recovery image in the tools folder so should I do that or put it in the platform tools folder?
In the instructions for the flashing recovery I am not understanding one thing.
6 - Then back on the SNS select Power Off (Reboot also works)
Part 4 - Root
1 - Power ON the SNS
So after flashing recovery I have to reboot? Since I am on stock rom that would bring back the stock recovery so how would I flash superuser then?
If I delete the stock recovery can I still get OTA updates?
fastboot and adb is now in platform tools, that is correct. Easiest way is to put your recovery in there too so you don't have to type in the absolute file path to it, don't put it in tools.
Don't power off or reboot the phone. After you flash recovery go straight into the recovery menu and root, flash custom ROMs, kernels, etc. You can transfer files to flash via the mounts and storage --> mount usb storage menu. After this feel free to reboot.

Good work, been wandering what you were up to on this
Hope you enjoy the possibilities.
So I've been reading these forums for days on end now before I touch my phone again. Is my order of things to do correct? (HTC One XL (AT&T))
1. Root
2. Supercid
3. Unlock bootloader
---Currently here---
4. Install CWM/make a backup
5. Relock bootloader
6. Flash a RUU (1.88?)
7. Unlock bootloader
8. Flash a rom
9. Enjoy
As shown above, I rooted, have su on my screen and I can get into the bootloader by vol down+power. I had a scare trying to install RUU 1.85 but I think it failed because my bootloader is unlocked?
Basically everything I do on my phone scares me now. I opened my bootloader today so I can see what stock recovery looked like. I got some weird icons that scared me. I cannot stay where I am because I cannot get OTA updates, and I cannot flash updates myself. HELP!
Thanks, people on this forum are awesome, but you all know too much to be able to write a proper noobs guide.

Those steps are correct EXCEPT for 5, 6 and 7. You don't need those if you're flashing a custom rom, only if you're staying official and using an RUU. We can flash insecure boot.img files now which allow us to jump around firmware versions without blowing up. Just make sure you do a factory reset from recovery before flashing a new custom rom to prevent any weird bugs (you can use Titanium Backup to backup all your apps). Also, I would personally recommend flashing TWRP over CWM. It's a little more friendly in terms of UI and has a bit more functionality baked in.
Edit: And just FYI, the RUU did fail because your bootloader was unlocked. And now you know.
Are you on 1.85 already? If so you are set. But if you aren't, relock the downloader by connecting your phone to your computer via USB in fastboot and typing fastboot OEM lock, upgrade to 1.85 and then unlock the bootloader once again.

Thanks for confirming why the RUU failed. I was scared because it never said it failed or errored. I let it run for 90+ minutes and finally did a hard reset on my phone.
I downloaded Titanium but I don't understand where the backups go. How to save them or how to use them for recovery. I also don't understand how people talk about this phone having an SD card when it doesn't.
I saw TWRP and it looked like the better option but I thought a lot of the roms needed CWM to flash from. I guess I really don't fully understand how to flash a rom then.
This is so weird because I jailbroke my iPhone 3g, and tried multiple roms on my cousins Droid X a long time ago.
Easy question. If you stick with roms, any reason to ever relock the bootloader?
Thanks

As the previous poster said, if I want custom roms I shouldn't even bother with the RUU? Is the RUU just a way to get the most updated factory settings because of root? Also do RUUs cancel root?

1. You never need to relock the bl unless you're RUU'ing
2. TWRP and CWM do the same thing, what you can do with one you can pretty much assume you can do with the other
3. Titanium Backup (I refer to it as TiBu) stores the backup files on your phone in a Titanium Backup folder on your sd card. You use the TiBu app itself to batch restore your apps. So this mean you're gonna have to redownload it manually from the Play Store after a factory wipe. You also have the option or restoring your apps with data and also restoring system data. In my experience, restoring system data is always a bad idea and will cause weird behavior. Restoring app data also sometimes has weird consequences, depending on the app, so I usually just restore my apps without data and individually restore data to apps I know will have no issue and are a pain to set up again.
4. We refer to it as an sd card because it technically still is one, just soldered onto the board.
5. Yes, RUU will get rid of root. It returns your phone to its factory state (except it doesn't touch your user data)

Upgrading to 1.85 isn't necessary since we can flash boot.img and jump between versions

You can have TiBu sync to a Dropbox, Google Drive, or Box account too. The scheduling feature is real nice. I have mine running the 2 default scheduled backup tasks every morning at 6am and then automatically uploading to Google Drive provided that I am plugged in and on WiFi.
I have it run every morning just in case I do something stupid during the day.
Oh and make sure to watch your internal storage space. CWM/TWRP backups take up A LOT of space, around 1GB (that's off the top of my head, I know it's around there somewhere). Manage your backups carefully, deleting ones you don't need.
you dont need to bootloader unlock before you upgrade to 1.85. just get the unlock code and then, with a locked bootloader, update RUU to 1.85. then afterwards unlock bootloader with unlock code.bin.

Thank you. I will run a backup from titanium and download it to my computer. Then I will flash TWRP, then try some roms.

Titanium is just for backing up apps not the entire phone. Sorry if you knew that, it just sounded like you didn't.
You need to flash TWRP and do a backup with it. This will backup your entire phone. In case you ever run into issues you know that you have a backup of your phone from when it was fully functional. This stays on your phone and if you ever need to restore it you do so from within TWRP.

Right, think of a TWRP/CWM backup as the equivalent of a Windows System Restore Point or a Mac Time Machine Backup. It's pretty much a snapshot of your system that you can jump back to in order to revert anything you did that screwed things up.

How did you try to flash the RUU? You can not flash it like a normal ROM
Also if you are looking for the RUU try HERE
I see what you're trying to do, that won't work...you can't flash a recovery to get to stock because stock phone won't flash from recovery, which is why once you get root the first thing you do is flash a custom recovery. Use the RUU to flash it back to shipped state stock, or if you are trying to keep root and just want to use a different ROM. More clarification on what you are trying to accomplish would be nice.
If you did a Nandroid prior to flashing CM10 I would wipe all partitions except SD and restore the Nandroid, if all you want to do is get CM10 off your phone. Remember Nandroid Backups are your friend do them before flashing anything and save them to your PC if you don't want the SD space taken. Doing this has made flashing pain free and hassle free. If I don't like how my phone is running after a flash I can always get it right back to how it was when I was happy with it. Lastly there was a time when I had a Nandroid backup of a Sense ROM and was on AOSP and wanted to flash back to Sense, well my Backup wouldn't flash. After spending hours raising hell I did a clean install of the ROM booted once, then rebooted into recovery and flashed the Nandroid backup that had the settings I was using (when I was on Sense, it won't restore data and apps used on AOSP)...sorry if its not much help but more details are needed. But you have a starting point.

i have installed CM10 without backing up any image, therefore i cannot restore the orifginal vendor's rom. Nandroid back would have prevented this situation. the second problem is that I couldnt find any RUU for this phone. indeed the link you attached seems to have it bu unfortunately it is in chineese and after pushing all the buttons i couldn't download the file. so my options are
1- to pray that someone will be kind enough to publish it in a manner that it is accessible
2- I have a friend with a simillar phone , can i somehow back up hus rom and restore it in mine ????
thank

Hey all,
So I have been reading around a bit now and was wondering if someone could help me understand some general concepts.
my goal: I am trying to remove all the bloatware from a Huawei y300 (no carrier) and put stock android on it.
From what I have been reading, it sounds like I need to first unlock the device, then root it to get access to superuser. Then what? Can I just use the superuser to remove the bloatware? Or do I need to flash it all and install a custom ROM?
Also, I should prob back the whole device up first so that if I mess it all up I can still restore the phone to the way it was when I got it from the distributor. Is that easily possible, or are there risks associated with that? If I mess up the phone real bad is there a big chance I will not be able to get back to its original state?
Now the details of how to do all this are burried in the forums, and I will figure all that out. I am just confused about the order of things a bit. So if anyone could give a high level explanation on the order of steps and the need for each that would be awesome!
Much appreciated, and thanks
The basic process is unlock the device, root the device, flash a custom recovery, flash a custom rom. Flashing a new rom is what will remove the bloatware for you, and you can find a stock android rom that will literally be the barebones version of android. Rooting the device allows you access to flash the custom recovery, which is needed to flash custom roms.
Everything as said above, with a nandroid backup added as soon as u flash the custom recovery is recommended.
BTW there are chances that u can brick ur phone if u don't follow the custom rom flashing instructions properly.
Anyway the nandroid backup will help u in this case.
In case if the nandroid backup even fails, which means there is a heavy mistake also there are very less chances of it to happen, u can try flashing the stock firmware.
Hit thanks rather than typing it
Got it thanks!

OK so I unlocked, rooted, installed TRWP recovery, and then used that to back up my phone. From what I read online it looks like backing up with TRWP is the same as backing up with Nandroid. I'm prob just not getting it, so wanted to ask what is the significance of Nandroid? Why do both TRWP and Nandroid?
