Need Help!

I Rooted my S3 and custom ROM ArchiDroid v1.7.18 using ROM manager, ClockworkMod Recovery.

Then I did a Factory reset from System settings.

Now after the reboot, I am getting the screen as:

Root access possiblity lost. Fix?

THIS CAN NOT BE UNDONE.

-No

-Yes - Fix root (/system/xbin/su)

Selecting anyone, just reboots to:

ClockworkMod Recovery v6.0.4.6

-reboot system now

-install zip

-wipe data/factory reset

-wipe cache partition

-backup & restore

-mounts & storage

-advanced

No option seem to work... Advices pls..

Reinstall I9300 from another Country

Dear all,

I have inherited a phone from China, which came with software installed by the local service provider. How can I "wipe" the phone and install a US version?

I am a complete new to phone modification and terms like "rooting" is new to me. :( As such, high level steps with links to other thread for details would be appreciated.

Many thanks!

I'm having a problem and I am 100% sure it's not ROM related.. That's all I'm really sure about.

It started for just some days ago. When I try to take a picture with my phone, it always ends up like "no image" (just a black/grey-ish color) this happens EVERY time i take a picture, it happens with the front facing camera and the back camera. I tried to flash several other ROMs but always ends up like how I did describe it.

Then I started notice when I try to take a screenshot, it ends up telling me it's not able to save the screenshot because the sd card is occupied by another process.

Also when I try to view a snapchat video (just a video, not photo) it says I have to plug in sd card into my phone to view the snap..

What I have tried:

Like I wrote earlier in this post, I tried to change to several ROMs but without luck.

Other things I have tried is to format my external sd card since I'm pretty sure that is related to all my problems, but without luck.

Then I tried something in the camera app, I changed the destination folder where my picture is beeing stored. I changed it to external sd card and now it works perfectly!

But this only solved my camera problem, nothing else. So the problem has to be in my internal sd card.

Is there anyone that know what's wrong with my internal sd card? And eventually know what to do to fix it?
[Galaxy S III Q&A, Help & Troubleshooting] broken920:
Extreme oc is dangerous because you may "cook" your phone but you can over clock it at 1.6-1.7 GHz without any kind of problem.

Have you tried with another version of Odin like 1.85 or 3.07?

Have you installed latest USB driver?

Verify md5 of the rom file.

Try to format internal SD card.

I have a GT-i9300 rooted and with recovery. Do i need to unlock bootloader In order to install a ROM for the first time or i can directlly flash the ROM's zip?
[Galaxy S III Q&A, Help & Troubleshooting] daantjuh68:
hey all,

My s3 has a problem, when i'm in recovery and then select install zip a file browser opens where to select the zip file. Normally the file browser would show all the maps of android. But mine shows only 3 maps:

/0

/obb

/data

In the map /0 there are all my files and the rom files. The problem is my phone constantly goes in to a bootloop and when i try a factory reset it doesnt remove all the apps etc. I tried all the format options in CWM but that doesnt work.

anyone has seen this problem before? and maybe how to fix it ?

[Help] Identifying correct stock firmware for I9300T

Hi everyone,

I need a little help. I've gone and soft-bricked my Samsung G3 I9300T and my attempts to flash it with various stock firmware have fallen flat. Can anyone offer me help to identify which firmware would be suitable for my I9300 as I'm led to believe there are differences eg. ZSALED (Hong Kong) vs UBALE6 (Brazil)

History of phone:

I purchased it off kogan a few years ago.

This is my first time rooting and flashing my S3 and everything's gone horribly wrong.

When I try to put it into recovery mode it will 'cycle' the Samsung Galaxy SIII title page but never reach recovery mode

I can put the phone into Download mode.

I've attempted to flash the phone with these firmwares:

-GT-I9300_TGY_I9300ZSALED_I9300OZSALED_I9300XXLEF.tar.md5

-CheckROM_V4_LG8.tar.md5 (from a thread: PM me if you'd like to know it)

-I9300XXUGMK6_I9300OXAGMK6_I9300XXUGMK6_HOME.tar.md5

(I use Odin3 v3.04-3.09 to flash these but everytime I run into a Fail)

Here's Odin log of fail:

Help with Galaxy S3 Base Verion

I bought a brand new unlocked GSM Samsung Galaxy S3 i747. Problem is, the base version ID is for Canada, as it is a Telus branded phone, but unlocked. went to AT&T and had a new sim put in, a\ctivated, and all was supposedley good.

I have big issues with data connectivity, and after 2 hrs with Samsung TS, they say it has to do with the fact it is a Telus phone (even though unlocked) and has a non US base version.

Do I just return the phone? I bought it from Amazon as a new. unlocked GSM phone. I bought an HTC 2 years ago same situation and had no problems, just had to change the APN.

With the G3, I can not get good data connectivity, can not talk and surf at the same time, and according to Samsung TS, it is because the base version is a MV instead of UC, Canada vs USA.

Is this something I can overcome by rooting, can I change the base version, or should I just send it back?

Thank you for any help!
[Galaxy S III Q&A, Help & Troubleshooting] kinc06:
I think you have the sch-i535 model so you shouldn't follow guides or install software made for the i9300...you will brick your phone.

This is what I found for the sch-i535:

1) The official 4.3 upgrade locked the bootloader, that means that you CAN'T install custom recovery (clockworkmod, philz, twrp etc), kernel or roms (cyanogen, aosp, carbon, slimkat etc...)... install any of those and you will BRICK your phone.

As of today you can't unlock the bootloader but there is a way to get root and install rom based ONLY on the TouchWiz interface and you can achieve that by using a recovery called SafeStrap

2) With android 4.0 and 4.1 there wasn't any kind of problem (because the bootloader was unlocked) and you could install whatever you liked (custom recovery, kernel, roms).

I don't know how to help you and because we don't have this kind of problems with the international i9300, most of us don't know what you're going through and can't give you solutions.

I suggest you to ask questions or read the guides in the appropriate section for the sch-i535 (here: http://xdaforums.com/galaxy-s3-verizon/general or here: http://xdaforums.com/galaxy-s3-verizon/help).

Hello GS3 community;

I want to hard reset my I9300 (Original ROM, 4.3) to make it faster and correct some bugs, but I don't want to lose some app data (mostly games).

So I searched and found out that I need root access to use Titanium Backup. The plan is to root it, Backup the apps, Hard Reset and recover. What's the most up-to-date and safe way to root this phone? If I do this method, will I be able to recover the data after the reset?

Do you have a backup of your /efs partition somewhere on your phone? I didn't think I did, but a few of the apps that I have on my phone created backups of it for me when I didn't even know about it. If you have Root Explorer, you can search your device for "efs". Look for a file that has "efs" in the file name, and ends with .tar. That will be an archival of your /efs partition. Find that file, and unzip it. Copy all of the files to /efs, and restart your phone. If it works, you have solved your problem. Make a backup of your /efs partition, and compress it with gZip. Make multiple backups of this file, (such as on your phone internal SD card, external SD card, desktop computer, laptop computer, external HDD, Dropbox, and Google Drive. You will now always be able to restore your /efs. You can never have too many backups.
