[Q] Regarding Android 4.2 update for yakjuxw

Hi, i have an unlocked Galaxy Nexus running Android 4.1.1 that has not received the android 4.2 OTA update. This is because my system is yakjuxw.
So i found a site explaining on how to switch to yakju or takju without loosing any data, apps etc:
http://andwise.net/?p=569
My questions are:
. Has anyone tried this?
. What are the cons?
. Does it void my phone's warranty?
Sorry if this has been asked or is posted somewhere else but i just cant seem to find it.
cheers!

It's completely fine. In fact there is a thread specifically about the process that's been around for months.

Cool! Can u point me to it?

You have the same search function as I do.

Clearly you have not read my last paragraph.
But thank you for letting me there is a search feature, technology these days... Next thing u know there will be a global search engine for the whole Internet

clearly you didnt even bother to read the stickies. any of them.

AS a matter of fact i did, and found ways to flash a rom wiping all data from my phone, which is precisely what i don't want.
Now, i would thank those who actually came forward to answers to my questions instead of arguments that lead nowhere.
Thank you in advance.

The process in the first link is fine and works.
However to point out a few important things:
1) If your bootloader is locked you have to unlock it with: "fastboot unlock oem" and continuing with the instructions on the phone which will eventually delete all your data. (if you have flshed a ROM before you know that)
2) do install CWM recovery ( you can find instructions to do that everywhere and also on the same page you found for the 4.2) and do a Nandroid backup. This way you can go back to your original system anytime you want (I do this all the time)
3) keep also other backups of apps and contacts I find google cloud pretty handy for that.
4) The instructions mentioned on this site works but it might happen that some app or library or database is not happy with the update so the device will go in a boot loop. In this case delete dalvik-cache (it might help), but if it doesn't help you will need to delete the data or the part that causes the issue for this you might look into the logcat.
PS: Zepius, Pandas are not so cute actually ... so what's the best ROM / Kernel (stock it isn't

Thank you!
I have flashed many roms in my old phone using CMW. Surely i don't want to debrand my new phone, so unless the bootloader is unlocked, i guess i'll be looking forward for the yakjuxw updates.
Thank you once more!

I used to think the same way as you and i also had the same yakjuxw but the updates come too late for those versions so i decided to go yakju and i have no problems now
My advice is that you do it, if you read carefully it becomes dead easy and its worth it

As written(linked) in the article this is just the software fingerprint I can assure you will not have issues as the main software is the same. The only thing changed is who is providing the updates. Imagine windows you get with dell and hp PC they both have their logos (yakju/xw) but the windows is the same s*itty windows
I used tohave yakjuxw, changed to yakju, takju back to xw.. not im on yakju. This is my job indeed to test apps on diff android versions and i flash time quite often every day and i can assure you all works fine
Anyway if you need a ROM that tells you it is xw let me know Ill upload one for you

Just to let future googlers know that the solution to convert yakjuxw to yakju as seen on this site:
http://andwise.net/?p=569
has soft bricked my phone! I was able to flash a new ROM using Gnex toolkit but (of course) i did lose all my data!
BTW, with android 4.2.2 i'm noticing that wireless turns off after i lock the phone, is there a way round this or is it a new bug ?

4.2.1 Update
I've got a Galaxy Nexus with the yakjuxw build. Previously my phone's Android version was 4.1.1. Just this morning I got the 4.2.1 update! Fire away on the Check Now buttons guys.

[Q] NOOb, Please Help (Regarding Flashing ROM's)

Hi XDA Community
Well i just need your help. I bought a Samsung Captivate Glide phone more than a year ago and now i think its time for flashing some ROM's since ICS is getting too old for me plus it is really battery and ram hungry. My phone really needs updating and i dont want to mess it through some wrong steps or process.
As i stated i am a noob and my only experience is Rooting my device with the help of XDA threads only.
I was hoping if there are people willing to help me in suggesting and flashing a good ROM (whether 4.2, 4.3 or 4.4 if any) because i was reading all the threads related to flashing and seemed kinda lost. Please can anyone help in explaining and directing me in steps (from backup to full flashing of ROM). For now i cannot afford to buy a new phone so keeping up with my buddy i927 glide.
Please Please Please, any help will be appreciated.
Simple step will be Good enough.
Thanks in advance to the XDA community.

The first thing you will want to do is get a custom recovery like TWRP (Team Win Recovery Project) or CWMR (Clockwork Mod Recovery).
You can find TWRP here. It includes all of the information you need to get started using a custom recovery, and its a touch based recovery program.
If you'd prefer CWMR, you can find it here.
Now, you will need access to a computer (and ODIN) to install the first custom recovery you want to use.
Download the (newest) ODIN version (onto your computer) of TWRP or CWMR from their respective download sites, and place your phone into download mode by restarting it, and then holding the [UP] volume button when its rebooting.
Now, assuming you rooted your phone already, you should know how to use ODIN.
After ODIN completes, reboot your phone into recovery mode, and you should see that you are in the recovery that you wanted!
The next step is to get Nandroid Backup and make a backup of your phone.
MAKE SURE YOU HAVE ENOUGH SPACE REQUIRED TO BACKUP YOUR DEVICE, OTHERWISE YOU WILL NOT BE ABLE TO RESTORE YOUR PHONE!!!
Now, you should be able to download and install a ROM, and install it via recovery.
Note: You must wipe your phone! All of it! Otherwise the ROM may not work!
For TWRP, just place the Custom ROM you want to use in either the root of your sdcard or in your ext-sdcard, and select that file in TWRP. Flash the file. If the ROM comes with custom gApps (Google Apps) as well, you need to flash them after you flash the ROM.
I have to go now, and will edit this later.

This is why I made my guide check it out in my signature!

Need help unrooting and going back to stock on my samsung galaxy s III

hey guys. I am kind of a noob, but i have been rooting my phone for awhile. I installed cyanogen installer and let it do all the work and i am having a difficult time getting it off because it is simply not performing well on my phone and I would like to just go back to the way it was. I have heard some complications about upgrading to 4.3 and then rooting and not being able to unroot and go back to stock samsung. Any help would be great. Odin has been failing and I just feel stuck. How can i unroot and go back to 4.3 on my galaxy s 3? Thanks in advance and sorry if this has already been answered. I am just having a hard time getting everything in order.

Thank you so much guys. I honestly bricked my phone earlier this week trying a different way and thankfully got it out of its endless loop. This worked. One more thing though. MY gps has gone to Sh*t. Any fixes for that? thanks!!

Glad to know it worked for you. Not sure about the GPS. You may try doing a factory reset to see if this will help.

Stuck on Samsung boot screen

I rooted my old milestone many years ago but havee been keeping my devices stock ever since, until today that is. Today I decided I wanted to try to root my Samsung SGH-I747M with Telus and everything seemed to start off smoothly. Once installed the SuperSU stopped working. I tried fixs I had read online such as updating the app, but this did not work. I read on a forum that you could flash something to disable know to help fix the problem. When I tried going this avenue I was not able to reboot my phone. I tried restoring from a backup taken before flashing, but I havent done any of this in so long im not entirely sure the backup took properly. At one point I got a message saying no OS was installed but after restoring this seemed to go away. I apparently do not remember anything about rooting from my milestone and am hoping someone may be able to help me get out of this mess. I am currently downloading the stock firmware and I think I will try flashing it tomorrow. I also was hoping someone could point me in the direction of a thread on xda that went into a more detailed explanation of how rooting works, what specifically roms and flashing all is and does. Any help is greatly appreciated.

The Only problem is I already attempted to follow this and my phone will no longer boot up. Also I tried navigating through the stickies. couldn't find much info for my device. I will be trying to flash the stock firmware tonight but I want to have a clear understanding on what flashing is and what the difference is between os firmware kernel and rom and such BEFORE flashing this firmware tonight. I hope someone will be able to help.

Well that info is already in the Sticky Index. Understanding what you're doing (or about to do) is really important but you gotta start reading, it's all there.
OS, firmware and ROM are the same thing.
When your phone boots, it basically goes: Bootloaders -> Kernel -> ROM (OS).
The kernel has pretty much all the "underground" controls (RAM, Mhz, governor, scheduler, BT, Wifi, etc).
I won't write everything but those are the basics.
Also, having a Canadian variant of the S3 (that's what the M is for), doesn't change much other than flashing bootloaders and stock ROM (which you'll wanna use the Canadian variant bootloaders and Telus ROM for stock). Everything else is basically the same.

Sweet I will definitely check that out. So I did flash twrp to my phone. Is it possible that I flashed the version say for the i747 but not the m version and that is why the phone wont move past the samsung screen? Also should I attempt to get rid of twrp before flashing the stock firmware. This should answer all my questions and then I will explore the stickies some more.

If flashing a stock ROM, flash the Telus one. If flashing a custom ROM, it doesn't matter (I747 or M variant), as long as it's D2LTE.
Your recovery doesn't change anything to flashing with Odin, it will overwrite it.

Flashing the stock firmware fixed my problems. Thanks for all of your help and I will definitely be checking out the links that you sent me before trying to root again tomorrow.
