[Q] Help please, SGH-I337 Z

Hello, my friends. I need help from us. I have Samsung SGH-I337 Z, I337ZTUUAMH1 4.2.2 android version. I need to update this telephone. I bought it with ROOT, Sim-Unlock yet. I want to update this for latest android version like a 4.3 or 4.4. I want to know can i do this or not? And if i can, how i can do this? Thank you, I counting on your help.

Help please

To get the ota update you need to return your device to stock. I googled i337Z firmware and found this http://forum.xda-developers.com/showthread.php?t=2448794
If it updates to 4.4.2 there currently is not a root method so if you need root you'll have problems.
Edit, oh, backup everything first as it'll delete everything

Help

You can try supersu's survival mode or hope that towel root works.

I can confirm that towel root works on the I337Z with 4.4.2, build TUUBNE2. However, Safestrap doesn't seem to work. Also, at least for the time being, I don't see any way of unlocking the bootloader with 4.4, so you may want to try to unlock the bootloader before upgrading to 4.4, if that's of interest to you.

agree I rooted a store demo with towel root and it worked hahaha , but I haven't tried safestap on a phone running kitkat , mine is running the intika rom now and I'm not planing to update for now

One thing that is a bit concerning to me, is that towel root requires internet access to function.. it makes me wonder why.
For the most part, I'm ok with the stock (rooted) rom, as I can disable/cleanup most of what I need to. The only thing I haven't been able to fix is the missing hotspot option - not sure how to get this option to show up.

[Q] Few questions about Razr M

I am new to Razr m i have a few question.
1. Is my device bootloader unlocked
In Fastboot I can see
Device is LOCKED. Status Code: 0
2. Are there any files of razr M that i have to backup first before attempting Unlock and root. I have S4 before buying razr M as my second devices in which i had to backup the efs partitions so that's why i need to know if some backup of razr M is needed.
3.Whats the latest official firmware of Razr M. Currently my device is on 4.1.2.
Thanks

No the M is on 4.4.2 now upgrade via ota if you can... The devices is not boot loader unlocked if it says that but you can unlock the boot loader if you upgrade it to 4.4.2... And no you shouldn't have to back anything up if you ever wanna go back to stock there's always rsd lite...if you need help finding all the links let me know there posted everywhere around here...if the ota fails let us know
Edit: I went ahead and grabbed all the links for you twrp for our device. root method for 4.4.2 Motopocalypse app for unlocking the boot loader

What he said except once boot loader unlocked there is no going back on that..
You can flash over the startup screen to give the appearance of not having it unlocked though

How is 4.4.2 update compared to 4.1 because I have read some bad things about 4.4 update like poor battery life. Should I unlock the bootloader first and then update or unlock it after update.
Which custom rom u would recommend to use as daily driver for better performance.
Sent from my GT-I9505

You have to update to unlock the boot loader and yes my battery life took a significant hit. I installed app ops and then disabled allot of the security location and keep awake items and battery life was alright again. No idea if there is a good choice for a 4.4 rom on this device yet but cm11 is getting close.

Absolutely unlock the bootloader, absolutely upgrade to 4.4.2 , before the 4.4.4 update is live to all phones. If it is already available for you, manually flash 4.4.2 and use motopocolpyse to unlock the bootloader. You might never get the chance to unlock your boot loader again.

So there pushing 4.4.4 to the M... Where did you read this at... I was under the impression that the next ota was just going to be bug fixes and a security patch to block the root and unlock method

Razr M Rooting and Updating issues

So I have Razr M and for some reason has been unable to update. I tried the verizon store and the guy working there tried many different things but nothing worked.
So now I am looking root and throw Cyanogen mod 11 on my phone. Only thing is I am still on Android 4.1.2 and System Version 98.15.66.XT907 since I cannot update for whatever reason.
So could anyone please point me to where I can find info on how to root this version?
Thanks for the help.

You could use RSD Lite to flash the official firmware.
Use Towel Root or Motochopper(Jelly Bean Only) to root.
If you want to flash a custom ROM, you'll need to unlock your bootloader. I believe the version you are on (.66) is unlockable, so is the latest version (KitKat). If this is what you want, the information is HERE but beware that unlocking your bootloader will void your warranty.

can you please tell me how to use RSDLite to flash the offical firmware on the phone? Will RSDLite require root?
Thanks.

It does not require root... There are several guides/videos online about how to use rsd just Google it... If you have any issues with the flash let us know...

if the bootloader is locked then it was locked before the update. if towelroot doesnt work then you are on too new of an update to unlock the bootloader, sorry.

As said above, if you didn't unlock your bootloader before updating, you're stuck.
You should have read through the forum first - updating to KK .10 and unlocking the bootloader in there is a good way, but you skipped directly ahead and there's no way of going back.

You're right - the reason Towelroot won't work is because the kernel is new and patched the exploit used in Towelroot. For now there's no other root method, you're gonna have to wait, maybe for months.
And Towelroot doesn't unlock your bootloader (Motocalypse does), which means even if there's a root method later, you still might not be able to unlock your bootloader, because the bootloader exploit might have been patched as well. So yeah, you're pretty much stuck forever.
Do a factory reset, install less apps, burden your phone less, and live with it for now.

[Q] Can't update to KitKat

So, I got this phone and it's running 4.1.2 (System version 98.18.78.XT907.Verizon.en.US) and I wanted to upgrade to KitKat but when I check for updates it says it's already up to date. What do I need to do to get the KitKat update?

Thanks! It worked

Even with locked bootloader?
Can I do the update to KitKat with a locked BL? I'm on the same 98.18.78 as the op and I have root on my otherwise stock 4.1.2 JB xt907.

yes you can update with locked bootloader, you can not downgrade with locked bootloader.
see [GUIDE][FAQ][KK] How to Root, Boot Unlock & More
I believe best option is flash VZW_XT907_4.4.2-KDA20.62-10.1_1FF.xml.zip with RSD Lite then unlock bootloader
do not use VZW_XT907_4.4.2-KDA20.62-15.1_1FF.xml it can not be unlocked at this time

WORKING!!! Thanks y'all!

Flashed VZW_XT907_4.4.2-KDA20.62-10.1_1FF.xml.zip with RSD Lite; file 15 which was system.img didn't want to load & kept telling me "fail" but I did NOT exit the Fastboot mode (don't like expensive bricks), I just kept trying until it worked on a different USB port.
Got root via towelroot.apk & then unlocked bootloader using motoapocalypse.apk.
Install TWRP recovery from http://www.droidrzr.com/index.php/topic/51942-recoverytwrp-2800/
Installed my apps & made a backup.
Works like a charm; thanks!

Thank you for updating to the unlockable version and taking advantage of it. Too many people ignore the warnings that .15 is not unlockable and beg for an unlock... Not gonna happen! Happy Flashing!
