[Q] Returning to stock [i9020a]

I just wanted to make sure that I understood the process of returning my phone to stock before I make a mistake.
All I've done since I purchased the phone was root it and unlock the bootloader. I have not loaded any custom roms.
So If I understand this correctly I need to:
1) Flash the Stock Image (which should include the stock recovery?)
2) Use fastboot to lock the bootloader
The reason I'm wanting to return the phone to stock is to receive OTA updates. I never use any apps requiring root, and don't plan on loading any custom roms.
I never did find a 2.3.4 stock image for the I9020A..

you should actually be able to get ota updates no problem. it'll just remove root every time you update.
it's probably not a good idea to lock the bootloader though cause if you ever want to unlock it again in the future you'll have to wipe everything from your phone. your best bet is to just flash stock recovery so you can install the update
i'm pretty sure that works, but hopefully someone else can verify just so you don't get some bad information lol

I heard the same thing about OTA updates. If you're phone is rooted and you're using the original rom, you'll get the update but you'll have to root your phone once again.
I haven't tried this myself so I cannot verify it.
It's just the word on the street, you know!

you need stock everything, so stock kernel, rom, radio, etc... the op should be fine to update if they flash stock recovery though. rooting is simple from there

Thanks kibmcz ! I'm a n00b when it comes to this but when you say flash via ClockworkMod you mean get into clockwork recovery mount the usb, transfer the zip onto the SD card and then <<Install from zip>> ?
Is that the method?

Thanks again kibmcz, so I just completed the flash, then did a fastbook oem lock.
Seems to be working fine except for one thing...
When I go into settings and hit Sound I get a Force close when I try and select a new ringtone...
Should I try reflashing again?

Didn't happen on mine (In fact im using a self rooted rom based on that exact stock zip) try doing a wipe in stock recovery.

after flashing that does it take it back to out of box condition?
reason i ask is because i bought a already rooted and unlocked one here from market place and i want to return it to stock firmware, radio, kernel and such to recieve OTA updates and what not.
your info is greatly appreciated

Using my zip yes... it flashes Bootloader, Radio, Boot, System and on first boot (and any other time recovery changes) Recovery is flashed. All you got to to is lock the bootloader and that wipes user data and usb storage.

hey man i appreciate you coming forward with a solution, ive yet to recieve the phone but wanted to prepare.
my goal is to flash everything back to stock and start completly over whereas i have no clue what method was originally used to root and unlock the bootloader.
when the time comes hope you dont mind a PM if i have any extra questions.

Just did the method using the stock ROM provided by kibmcz "thanks BTW!"
Phone is back to stock, working like it did when I first bought it. Had a little trouble with some Force Close issues but did a factory reset/data clear of the cache and all that before re-flashing, and it seems to be working Vanilla!

[Q] Update Nexus S from 2.3.6 to 4.0.3 manually with a broken power button

Hello everyone
I own a Nexus s I9020 T-mobile. and I'm using it on Vodafone.
My power button stopped working a month back and I'm using widgetlocker lockscreen to unlock.
I did not receive the OTA for ICS last month and i would like to have it on my phone by doing the update manually.
Is there a way to do the update manually with a broken power button ?
Thanks

There is a clockwork recovery with touchscreen interface I can't remember where I saw it though. So you could use that to flash the ota. Or you could flash the boot and system images directly through adb if they have been posted somewhere. You will have to root your phone before you can use these methods

thanks .. but I think the touch based clockwork recovery is only avilable for Galaxy Nexus and more over I dont want to root my phone unless it is absolutely necessary .. because i'll have to re-install all my apps
is there any possible way to do it without rooting ?

The Clockwork Recovery you are looking for is named TWRP (latest is Version 2.0.0). Look at the offical site - http://teamw.in/project/twrp2 - choose your device (NS or NS4G) and install via adb
Good luck

Thanks mate
should my device be rooted for this ?
and after installing clockwork recovery how do I flash the update.zip file via clockwork, any guide ?

I have a new posted guide which should be useful for you, but you have to have it rooted first.

will try it out .. just hope I don't brick my phone 'coz im going to root my phone for the first time
looks like you have gone back to CM7 from ICS
should I overlook ICS too, coz im pretty happy with GB right now.

You don't need to flash TWRP. In clockwork mod recovery back is back, menu is down, search is select, home is up.

even to flash ClockworkMod or TWRP, first you will need to unlock the bootloader right ?
for this again the need for power button arises..

Make sure you are not plugged into your pc when you boot to recovery! - if that doesn't solve it ..
Does the phone boot to the existing Rom, do you have Rom manager installed? - if so update the recovery from Rom Manager. I found that after rooting the One S using the toolkit I could not get in to recovery, the update from Rom Manager sorted it!
All the best :good:

Had same issue with the tool kit, the cwm didnt stick. The Touch work one did stick and I was able to get into recovery. However I downloaded the app ROM MANAGER and flashed the recovery from there. Since then I've had no issues booting into reocvery or bootloader. Just download rom manager and go about it that way!

Which recoveries have you tried, and what version of phone do you have (S3 or S4). These must match.
Make sure you bootloader unlocked OK, check in bootloader screen, should say Unlocked.
The problem youre describing sound like when you try to boot after successfully flashing a ROM but forgot to or the kernel failed to flash with it. Only happens when ROM and kernel are mismatched enough that it wont boot, fex flashing CM9 and still on HTC original kernel. Try flashing the kernel from the ROM zip file with
Code:
fastboot flash boot boot.img
You can also try booting a recovery without installing it,
Code:
fastboot boot nameofrecoveryfile.img

If you have working ADB and fastboot working (there is a sticky by user fibsib that explains this) you can make sure your phone isnt really just trying to boot the OS and failing rather than trying to enter recovery with the command
Code:
adb reboot recovery
But anyways figure out which version you have before doing anything more, flash the wrong stuff and you could break stuff. There are good info here as to how to see if you have the Ville=Z520e=S4 processor model or the Ville C2/Z560e/S3 processor model.
Then download a recovery for your phone model and install it with this command from your computer
Code:
fastboot flash recovery nameofrecoveryyoudownloaded.img
Should work.

have you actually flashed a recovery yet?
which one and how did you do it?

Make sure you have your phone updated to the latest software version before you root. Download system update OTA and click update.
Otherwise you will have issues.
I am rooted T-Mobile phone with original software 1.54 and still can not do recovery or update, it is probably me but it is difficult.
If you are in the US, make sure you use the US version in the development section after you upgrade your phone. Update then try to root it might be easier.

[Q] Root and Custom recovery not sticking...

curious if there is something i'm missing here... i've unlocked my bootloader successfully but whenever i fastboot flash a recovery or flash root files in recovery nothing seems to stick... not sure whats going on... i've heard of having to flash recovery everytime on devices with a locked bootloader but i didn't think that would apply here... any help is much appreciated... (this is also my first samsung/nexus device so i'm more familiar with methods used on the EVO line)

Make sure you're using a perm root method. and make sure you have the correct updated SU application. My root wouldn't come through because I didn't have the latest SU.
Hopefully I helped.

By default, any recovery you flash on the system will be gone by the next reboot. This is a security measure the android os does I think.
1. You can flash a ROM. Anyone. I prefer aokp or cna. That way the recovery sticks (the recovery sticks on all the ROMs besides stock)
OR
P.S. You will need the latest cwm recovery
2. So all you need to do is to flash the recovery of your choice. I would recommend CWM for this short guide. Then once flashed go to the recovery make a backup. Then if it reboots flash the same recovery again. Boot into it and restore that backup. When you restore it and go reboot system now it should come up with a menu saying recovery flash fix (or something around those lines). Hit/navigate to yes and you should get a sticky recovery from there. BTW I have not tried this method.
You cannot blame me for bricking, damaging or done anything to your phone
Hope this helps.
Regards,
UselessSniper001
P.S. I don't know how root isn't sticking. I mean if you have flashed the su is the recovery already well then you are all set to go. Unless you haven't actually flashed the su in the recovery. Then flash the recovery from your PC boot into the recovery and flash the su files in the recovery. Reboot and enjoy. Then follow this guide above. Or follow this link:
http://forum.xda-developers.com/showthread.php?t=875875&page=2

I finally figured out the SU and CWM I was flashing was ancient so I found the newest and they stuck with help of the fix ya mentioned inside CWM... Thanks

[Q] Flashing Recovery on Latest VZW Version

I had my phone bootloader unlocked, CWM loaded, and rooted. I decided I didn't really need root and was messing around so I took the VZW update which, of course, required me to flash the stock recovery.
Well, I wanted to play with the new CM 10.2 so I went to flash CWM back on using mattlgroff's utility and while I don't receive any errors and it reboots the phone, the stock recovery is still there.
Any way to flash a recovery or am I hosed? I thought it was only motochopper I couldn't use on the new VZW firmware.

Flash recovery manually.
Turn on USB debugging
Open the folder that has the tool files. Find the one that had adb, fastboot and aapt. Go up one folder. Hold the shift key and right click the folder that has adb etc. There is a option in the right click menu that says something to the effect of 'open in command prompt', select it. in the command prompt type: adb reboot bootloader Hit enter.
Copy the cwm img file into the folder with adb and fastboot. Go back to the command prompt. Then type fastboot flash recovery <name of recovery>.img Hit enter. If it doesnt reboot type: fastboot reboot Hit enter.
Enjoy.
Tip: when typing the name of the cwm image type the first few letters then hit tab to autocomplete the name.

Unfortunately, while the commands went through without error, it still has the stock recovery.

When you go into the bootloader it does, in fact, say you are unlocked?

I was using mattlgroff's utility and the first time I tried CWM it failed. I didn't have my phone rooted, but I had the bootloaded unlocked. So, I just rooted the phone and reflashed CWM and it was fine. I think that same utility has the old software on it, so if nothing else, just flash the old software, root, and then install your recovery.

You shouldn't but these phones are a bit wonky when it comes to that sort of stuff. For example you dont need root to unlock the bootloader on any other phone except this one.
What does the stock recovery even look like? Ive never been there. After flashing the recovery how are you getting to recovery? Are you using the terminal or command prompt on your computer or are you holding the up/down/power combo the arrowing down to recovery and then arrowing up?

Ive found the solution to this if you still haven't...
You need to have root. How you get that is up to you. I flashed back to the last rootable OTA, rooted, used voodoo root keeper to backup root, then took the OTA and restored root with voodoo. Once I had root again i used Root Explorer to rename the file called recovery-from-boot.p in /system . Then I booted into fastboot mode and flashed the recovery like normal. That was it.
