[Galaxy S III Q&A, Help & Troubleshooting] VIOShero:
Hey guys ! It's the first time I post on XDA , this is a bit long but I think this problem could be interesting :

A couple of weeks ago I purchased a Galaxy S3 i9300, with a Mexican company . Stock Android 4.3, is all the information I can remember.

I gave myself the task of flashing it . CWM 6.0.4.7 ( Touch) , SuperSU v1.91 , I did my backup system . Everything was perfect. I changed Rom ( SlimKat to be exact) and BAMMM ! .

I rebooted and my imei was gone , had the generic imei ( 00049 ) obviously had no signal . I tried in every way I could to get it back (EFS pro , Root Browser , KTool ) but although there is much talk about it, I could not restore . I read in many forums , including here , and nothing worked . When I could restore it, that I restored the imei no imei matched the coming back of the battery, but already had service. Well, one step at a time.

How did this happen ? I have no idea. As far as I know, this is illegal. I did a back up again , and try to regain that blissful imei , probe almost all methods until I came across a user who claimed that flashing the Stock Rom with Odin could restore my imei .

Use this: GT- I9300XXEMG4_KOR_MULTI_FACTORY.zip

These files are included :

BOOTLOADER_I9300XXEMG4_1314436_REV00_user_low_ship.tar.md5

CODE_I9300XXEMG4_1314436_REV00_user_low_ship.tar.md5

CSC_I9300OXAEMG4_KOR_FACTORY_user_low_ship.tar.md5

MODEM_I9300XXEMG4_1314436_REV00_user_low_ship.tar.md5

mx.pit

It's an Android 4.1.2 Stock rom.

I followed every step except the bootloader . The user recommended not flash it .

But ! I had no idea what was going to do the PIT ( so desperate was that faith was a question of what motivated me to do it ... ) . Everything had disappeared in SDCard . Even my backups ... sad, but true. I un updating to version 4.3 of Android , with the Stock rom from Telcel. Everything works, but the imei still does not match .

I made a backup (again, and this time keep it in my pc) . SlimKat here we go again . but! ! No longer connects to wifi (before this mess could do ) . Save the network but does not connect, says the signal is poor are near the route .

I searched and searched on the net. Some said it was the DHCP configuration, not work, that I was to connect with static IP . Other hallucinated weird stuff ... tried changing the kernel, the Telcel csc , modem and nothing worked ... Returning back ( android 4.3) everything works perfect, but with any other rom happens.

I would appreciate any help you could give me . Is that much of this is due to my ignorance ... anyway , thanks. !

P. D. I can not write good English
[Galaxy S III Q&A, Help & Troubleshooting] boomboomer:
IMEI problem usually due to flashing a kernel or modem incompatible with your efs version.
[Galaxy S III Q&A, Help & Troubleshooting] VIOShero:
I read about what you mention. I have this in the baseband: I9300XXEMG4. I have understood the corresponding EFS v2. you're absolutely right, I made a bad downgrade. But then what is baseband I can fill with jellybean kitkat 4.3 or 4.4.2?

[Sony Xperia Z Ultra] Pannam:
hey guyz

i just started playing an online game. When ever i minimize the game and try to reopen it doesn't start from where i left. instead it loads first etc.. i guess ya'll know what i am talking about.

is there a way to keep it running actively in the background such that it doesn't load when i bring to foreground?
[RAZR HD General] odorfreedk:
Hello, I was wondering for those who kept root going from 4.1.2 to kitkat 4.4, how did you do it? My phone is currently locked but rooted and I just downloaded the OTA kit kat update but haven't installed it yet. Any ideas would be greatly appreciated!
[RAZR HD General] TWong1200:
No current method so don't upgrade if root is essential. Only unlocked bootloaders can get root back.
[RAZR HD General] RikRong:
We haven't seen anybody maintain root on a locked device across the OTA yet.
[RAZR HD General] MacGyverHatesGuns:
what about on a device that is unlocked?

voodoo?
[RAZR HD General] killrhythm09:
On an unlocked device you can just flash SuperSU in recovery...

And Voodoo won't work with a KitKat OTA.
[RAZR HD General] davekaz:
how do you flash if root was lost when updated..im unlocked and had twrp but heard that is no longer working..and what is stranger is that developers option in settings s not there
[RAZR HD General] iBolski:
First off, in regards to TWRP, there is a newer version of CWM recovery that works with KK. Use that.

Second, the developer options have been hidden, but you have to pay me to get the info.

JUST KIDDING! :D

Here is what you do:

Go to settings.

Click on "About Phone"

Scroll down and then start mashing on "Build Number". It will inform you that you have so many presses before going to developer mode.

After that, it will give you a toast saying developer mode has been activated. You're done!
[RAZR HD General] MacGyverHatesGuns:
If someone could kindly put together a walk thru on

How to go from stock, rooted, and unlocked to kit Kat w/root

That would be greatly appreciated.

Thanks!
[RAZR HD General] gadsden:
I am in the same boat, rooted on stock ROM. I don't want to lose root, but my phone keep popping up the update installer request. My phone has kept me so happy for so long that I have not kept up with the forums. I just haven't had any problems, and I'd like to keep it that way. So, is there no root for 4.2.2 yet? Or there just isn't a way to preserve it across the OTA? Should I go back to stock unrooted, update and re-root? I've been reading around the forums and I am just not seeing a whole lot of info about this yet.
[RAZR HD General] bweN diorD:
this has been discussed many times.

if you have a LOCKED phone, there is NO way to have or preserve root going to KK

if you have a UNLOCKED phone, update to KK, flash the KK cwm, flash su zip in cwm, profit!

those are the only 2 options PERIOD.
[RAZR HD General] gadsden:
Ok, well, I am not unlocked. So is there a way to stop the OTA?
[RAZR HD General] bweN diorD:
you can freeze the updater. i dont recall the exact file name(s).

someone else can jump in, or you could google it.
[RAZR HD General] RikRong:
You are correct, just freeze the updater.apk. Well, it's worked for me anyway.
[RAZR HD General] gadsden:
Some people say it's better to rename System > etc>security > otacerts.zip. Equal amount of people say to freeze updater. I'll follow you and freeze updater for now.

I'm itching to update to KK, and I can almost part with a rooted phone since I am running stock ROM anyway. But life without Titanium Backup just doesn't seem like a life at all.

Thanks again for the tips.
[RAZR HD General] sheep348:
Speaking of freezing the update app, I have been doing that since before the last update so I'm currently running 4.1.2 9.16.6.XT926 does anyone know if it will cause me any trouble skipping an OTA?

Thanks.
[RAZR HD General] bweN diorD:
you should unlock the bootloader first if you havent already. after you update you will no longer be able to ever.

as for the update, if you flash it with rsd there shouldnt be any issue that im aware of. if you unfreeze the updater and take the actual ota(s), it will not skip any, it will pull the next in line each time until you get to the most current.

however, you will still need to use rsd before taking or sideloading the KK ota or root will cause it to fail.
[RAZR HD General] sheep348:
Thanks for the help but I don't have a lot of knowledge about rooting. If I don't care about keeping root can I just take the OTAs or are you saying they will they fail if I don't first unlock the boot loader?

"after you update you will no longer be able to ever" What will I not be able to update again? The bootloader?

Thanks.
[RAZR HD General] gadsden:
He's saying you could probably find someone who would be willing to pay you handsomely to trade phones.

Once you update your phone, the bootloader can't be unlocked....as far as we know, ever again. If you don't care, which it sounds like you don't, go ahead and update your phone.
[RAZR HD General] bweN diorD:
most people who dont unlock the bootloader when they had the chance regret not doing it. its not a problem if you dont want to, i was just giving you a heads up more or less.

as for the updates,(this has nothing to do with the bootloader) im pretty sure the first 2 will install fine but im positive the 3rd, KK, will fail because you had root before.

so if you want to go to KK, you really have no other option but to use rsd first to return your phone to stock.
[RAZR HD General] sheep348:
Thanks bweN diorD and gadsden,

I appreciate the help. I only use my root access for killing music apps and I have some bloatware frozen. So personally I think I'll go ahead and update to KK since the benefits should outweigh the loss of root access for me. Should I do a factory reset first or should I be good to go taking the OTA?

Thanks again I'm always hesitant to do things to my phone because I don't have the knowledge to fix it or the money to replace it.

---------- Post added at 06:18 PM ---------- Previous post was at 06:15 PM ----------

Again thanks, I guess I'll have to look into finding out how to use rsd and go back to stock.
[RAZR HD General] bweN diorD:
ahh the plot thickens lol

you froze bloat, no update will install in that case.

you need to use rsd first.

btw, if you unlock the bootloader now, there is almost nothing you can do to brick the phone, short of installing the wrong phones software.
[RAZR HD General] sheep348:
I still have root and titanium backup so I can unfreeze those apps before the update. Will I still have to go back to stock?
[RAZR HD General] bweN diorD:
unfortunately yes, root is something you cant get rid of without flashing, so there is no point in trying any ota's you will have to flash back to stock at some point with rsd. i suggest you just do it now, its the smartest course of action.
[RAZR HD General] iBolski:
You don't have to go back to stock right now. You can unlock, if it's unlockable that is. But you MUST be rooted in order to unlock the bootloader.

Here are Dan's instructions -> http://vulnfactory.org/blog/2013/04/08/motorola-bootloader-unlocking/

Here is the download you need -> http://vulnfactory.org/public/motopocalypse.zip

Worse case scenario, if someone upgraded it to a higher OTA that fixes the exploit, you won't be able to unlock it, but it will not harm your phone attempting to unlock it. However, Dan (the person who found the exploit) and I do not take any responsibility if something should happen to your phone. However, no one has ever had a problem from trying to unlock their bootloader, so it's safe. Still, need to put the disclaimer there, you know.

Unlocked does NOT prevent you from getting OTAs. It just allows you to do more. In fact, if you go to KK right now without unlocking, TiBu won't be able to restore your app data once on KK since that requires root. You will still be able to backup the apps themselves and restore them, but that's it. You won't be able to backup and restore your app data. For that, TiBu requires root.

As for obtaining root, for unlocked bootloaders you just sideload an image of SuperSU via a custom recovery. In this case, CWM. That's it. No exploit needed what-so-ever. But first things first, you need to try getting it unlocked. Like I said, if you can't unlock it, no harm, no foul. So, go to the two links and follow the directions.

Go for it. You have nothing to lose but root if you can't unlock it. If you can't unlock it, you can still go to KK but no more root.

Having an unlocked bootloader is not like freezing bloatware or putting in a root exploit. Those modify the system files which does prevent OTAs from being applied until you go back to stock. Unlocking the bootloader is a physical change in the phone. There is something called an eFuse. When this eFuse is still present, the phone senses that it is locked. Dan's exploit causes this eFuse to "blow", in a sense, which cannot be reset once it's blown. That eFuse is what tells the phone if it's locked or unlocked. Once it's blown, the phone senses it is unlocked and there is no way to reset it. Hence, the "physical" change. But, that will not prevent you from getting OTAs as it's not part of the OS system. It's part of the hardware system. But, it doesn't break anything and it doesn't damage your phone.

Take it from me and countless others who have done this. It's worth it.

You'll be glad you did it. I know I have many times.
[RAZR HD General] sheep348:
Thanks! I won't ask you how to go back to stock step by step but would you be able to point me in the right direction? What should I search for to find instructions since I don't know the vocabulary?
[RAZR HD General] iBolski:
Before you go back to stock, read my previous post about unlocking. Read it and ensure you really want to go to KK without unlocking your bootloader, especially about TiBu. It won't work under KK unless your rooted as far as restoring your apps and their data and rooting with a locked bootloader under KK is impossible. You have to have an unlocked bootloader.

Just want to make sure you understand the implications if you don't at least try to unlock it. Again, as I state in my previous posting to you, if you can't unlock it, no harm no foul. Your phone will still be the same.

we have been over this before you jumped in, i stressed it as you did.

he/she doesnt care to unlock, no point in beating it to death imo
[RAZR HD General] sheep348:
This post is saying that the KK update will not install unless I unlock and go back to stock. But others have said I do not have to unlock if I don't want to do it.

So if I unfreeze all my bloatware in titanium backup and take the OTA, will the update fail or will I have KK without root?

Thanks everyone for helping out.
[RAZR HD General] Faethor420:
He, (Dan) and his talents are sorely missed! Is there anyone left hunting for exploits in these old-ish Moto's? I'm semi-noob so not sure if, when it comes to the bootloader, if there is truly any universal-type exploit even feasible, so as to hold out at least THAT little shred of hope...???
[RAZR HD General] iBolski:
Sorry, I didn't mean to butt in. I read what you had stated, but the poster never mentioned TiBu before all that. Once I saw that, I wanted to let them know that TiBu wouldn't work anymore if they upgraded to KK. That's the only reason I responded with what I did because I wanted to make sure they understood that once they got to KK, TiBu would NOT be able to restore their apps and the data associated with them since that requires root.

Again, I apologize. Just trying to help.

If I could, I'd buy you beer, but that's hard over the internet. So, maybe this will have to do:

---------- Post added at 08:33 PM ---------- Previous post was at 08:31 PM ----------

I doubt it. Dan worked long and hard on that particular exploit and we were lucky it was there and that Dan found it when he did. Once it was known, that's when they patched it with an OTA and it has now since been forever lost to those who didn't take advantage of it since it's in a protected zone.
[RAZR HD General] bweN diorD:
you misread or dont understand what i explained.

you absolutely do not have to unlock to go to KK.

however, the KK ota will fail because you have/had root.

it doesnt matter if you unfreeze the bloat, root or previous root will make KK fail.

---------- Post added at 08:37 PM ---------- Previous post was at 08:33 PM ----------

its all good :)

he/she will regret not doing it later, they always do, you were beating a dead horse lol

no worries
[RAZR HD General] iBolski:
Yeah, it's a shame because there definitely is someone out there that would want that phone unlocked. I don't know how I could survive without mine being unlocked and I got lucky as it was a warranty replacement from Verizon for my DROID RAZR MAXX. Not sure how I got one with the exploit still on it. :good:
[RAZR HD General] sheep348:
I was misunderstanding. Would your recommendation be to unlock with the instructions from iBolski and then take the OTA? Or do i need to unlock and go back to stock?
[RAZR HD General] bweN diorD:
yes, i recommend unlocking and yes, unfortunately, no matter what choice you make you will need to flash back to stock. it has to be done or you cant have KK.
[RAZR HD General] gadsden:
They're saying that if you don't take the short lived opportunity to unlock the bootloader now, before you do any updates, you will never be able to again. Once you update to KK, you will no longer have root, nor will you be able to get root access again. This means you won't be able to use Titanium any more and you definitely won't be able to restore any Titanum backups. Are you okay with that?
[RAZR HD General] iBolski:
If you're still rooted, then unlock it now. You have to be rooted in order to unlock. So, here are the steps:

Unlock the phone now.

After unlocking, go back to stock 9.30.1. Make sure you have it wipe data.

Activate your phone and take the OTA for KK.

After the update to KK, flash CWM to your phone so you can then proceed to root the phone.

Use CWM to sideload root.

Profit in the glory of an unlocked bootloader and root for KK. It is worth it.

But, first try unlocking the phone and inform us of what happens before you proceed. We are all waiting with baited breath to see if your phone can unlock. If it does, you won't regret it. And definitely, read it all before you even begin to attempt. If for some reason you don't understand something, please come back here first and ask before attempting anything. We want to ensure you do everything right. You shouldn't have any problems, but I know it can be daunting if you're not used to this and we want to help.

After that, we can assist you if you need to for the next steps to go back to stock. The utility to use is located at the link below with instructions but don't do this until after you've attempted unlocking your phone and telling us how it went:

Thank you so much. I will have to review those instructions and I probably won't get to do it before Thursday evening but I will keep everyone posted in case there are other people in my position who want to keep root. Just to be clear I will be looking at these two following links to unlock first then I will move to going back to stock.

[RAZR HD General] ThePolymath:
Does anyone have any idea of a timeframe until KK can be rooted? I have an XT926 with a locked bootloader on 4.1.2 and 9.30.1, that means I definitely can't unlock right? I'm going to use this method (www dot droidrzr dot com/index.php/topic/45494-how-to-xt926-upgrade-to-kitkat-ota/) to update my wife's phone tonight because she doesn't care if she loses root but I don't want to lose it.
[RAZR HD General] sheep348:
I'm looking at the instructions to unlock and it looks like all I have to do is install the drivers, which I am doing now, and click the run.bat file so hopefully everything goes smoothly.

The instructions say "3. Ensure your device has been rooted and you have a working installation of “su”."

I assume if I am using "SuperSU" I'm good to go?

EDIT

I wanted to report I ran the unlock utility and I think everything went ok. But how do I know I'm unlocked?
[RAZR HD General] bweN diorD:
reboot the phone, if its unlocked there will be a big WARNING screen before it boots. its unmistakable.
[RAZR HD General] sheep348:
Thanks I just figured out to hold down both volume buttons and check to see if it is unlocked. Mine still says locked so I'll try again later tonight and report back to everyone. I installed the drivers and followed the prompts but maybe I missed something.
[RAZR HD General] bweN diorD:
watch the script as it runs and post back any errors, maybe we can help determine the problem.
[RAZR HD General] iBolski:
There is no time frame and I wouldn't hold your breath. I would say the chances of finding another exploit to gain root under kk are slim to none. As each exploit is patched, that's one less option of getting root.
[RAZR HD General] RikRong:
Safe Root was just pure luck that it worked on the Razr. There has been no new exploit since then. It might be a long time for root if you're locked. If you want to know how hard root for KK is, take a look at the S5 forums and the root bounty that is over $12K.
[RAZR HD General] sheep348:
Not sure what I did differently but the second time I tried it the phone was unlocked in about 3 seconds. Tomorrow I'll read up about going back to stock and taking the OTAs.

Thanks again everyone and hopefully some people can learn from my trials.

Corbin.
[RAZR HD General] iBolski:
That is AWESOME. I'm glad you got it to work. Now, you will be able to achieve root without having to do it via an exploit. This will make your life so much easier, especially when you're ready to go to KK.

Getting your phone back to stock will be easy and then getting the OTA will be a piece of cake. If worse comes to worse, SamuriHL's instructions will provide you with all the files you will need to get to KK.

I seem to remember when I did it, I think I had to do it twice because I didn't do something correctly or something like that.

Congratulations on having an unlocked phone. You will not regret it.
[RAZR HD General] sheep348:
Ok I am going to attempt to go back to stock!

1. I installed RSD Lite

2. I downloaded Android 4.0.4 Blur_Version.0.6.25.XT926.Verizon.en.US from http://sbf.droid-developers.org/phone.php?device=5

3. Already had the latest drivers from the unlocking process.

4. Opened "VZW_XT926_4.0.4-7.7.1Q-144_VQW_S3-34-25_CFC.xml" removed the two lines and did not leave a space between the lines.

5. Opened RSD Lite, selected the xml

6. Waiting for phone to charge all the way and backing up.

I'll be back in a bit with the rest of my steps.
