[Q] Flashing stock firmware - Galaxy Tab 3 Q&A, Help & Troubleshooting

I have a rooted P5200, and I've been thinking of flashing/odining the new 4.4.2 Spanish stock firmware (running 4.2.2 stock). Do I still have to do a full wipe even though I'm running stock, like when flashing a custom ROM? I'm really careful with these things, and am taking no risks so I won't brick, but I don't want to wipe my device unless there is no other choice. Please hear me out

Everything on your Internal Storage will be Wiped !
I suggest you remove SIM Card and SD Card before flashing.
It's risky if you don't know How to do it ! It can seriously harm you device
I suggest you take it to a Flash Center so that they can flash it for you.
Or maybe you can use Kies which is least dangerous than ODIN.
Good luck.

[Q] Questions about the new 4.3 ROM: downgrading, KNOX and others

Hi there, I'm about to flash the brand new official 4.3 ROM in my Note 2 N7105. I've read some concerns about KNOX and it changing the bootloader and making impossible to downgrade, it that true?
If I flash this new 4.3, can't I reflash the 4.1.2 ROM using a nandroid backup, or even with Odin?
What about using 3rd party ROMs, would I still be able to do it as I do now? Any risk of EFS / IMEI problems? I am currently using both the 4.1.2 and CM 10.3.1 (I alternate frequently using nandroid backups with CWM), don't know if it's worth the risk of upgrading to the official 4.3 right now before knowing this and if CF-AutoRoot can root the 4.3 ROM.
Note: I don't care about warranty and KNOX at all, if those are the only issues.
It is fairly simple - if you flash 4.3 with Knox, you can't ever again flash any other custom ROM without loosing Knox. What it means is that, once you flash anything else, Knox will burn something inside your chip - and this is irreversible - and it will know your device has been modded. And you can never again use Knox.
If you don't care about Knox - this is no issue....

I flashed with Odin and lost WiFi. I tried to install a patch from another thread, but it seems that doesn't work on for the N7105, as I lost my IMEI and the phone doesn't get signal. I have an EFS backup, gonna try downgrading to 4.1.2 and restore the EFS (it doesn't allow me to do it on 4.3, it says that "a dangerous action has been blocked").
Help, I can't get my IMEI back, it seems that the EFS backup was useless Have I bricked my phone? I think it hasn't really lost the IMEI, it just forgot how to search for it, because I installed the wifi correction .bin file for the n7100. Any help?
good questions.. waiting for replys?

[Q] Stuck on Beanstalk rom after trying to restore to stock 4.3

Hey guys, sorry if this wasn't my place to start a new thread, but I can't find any others that help
I achieved root on my stock 4.3 rom and decided to go try some of the new 4.4 roms. However I was using TWRP at the time and it wouldn't restore my backup I made of the stock rom. So then I tried to install a custom touchwiz rom instead, and ended up hard bricking my device. It is now revived because I used the sd card method to boot, however it is back to hard brick if I try to remove the sd card. In circumstances like this I would normally Odin back to 4.1.1 and start from scratch, but as we know the bootloader has been locked which prevents downgrading. Any help out there? I messed up bad and now I can't restore to the stock firmware :crying:

Reflash the bootloader, rom, kernel and modem to the phone. You should be good. I did that to my phone 3 times last week.

I have tried that, at least 10 times over, it still does not help. If my phone is bricked like this, can they tell if I have been rooted? Because at this point I may have to go in with puppy eyes to try to get it fixed.

Are you on stock Rogers 4.3? If you are, loading a custom recovery will void the warranty by tripping the Knox counter.
If you have no warranty and just want to install a custom ROM, you can install a custom recovery via Odin and flash the ROM you want.

Yes im on stock 4.3 but my warranty is over so it doesn't really matter I have TWRP recovery so if I want to flash a rom there is no problem ?
I made a nandroid backup in case

I prefer Philz Touch which is based on CWM because I had problems flashing with TWRP.
There should be no problem as long as the ROM is supported by TWRP.

You shouldn't just go around flashing all the ROMs you think look or sound cool. I would suggest doing your research beforehand. For example, if you want to install the newer KitKat ROMs, you HAVE to be on a JellyBean bootloader. Click HERE for the bootloader guide if you need it.
Also, your TWRP should always be up to date. The link for the latest (may be outdated, idk...)TWRP is HERE
Lastly, if you ever run into any problems and want to go back to stock, or you just want to start fresh and start from scratch, then use this. This has never failed on me. Click HERE
Remember, YMMV.
Best of luck!
I don't think you need a 4.3 bootloader for all ROMs. I have loaded Cyanfox, CM11, and Vidalus which are all 4.4.2 ROMs without issue. I personally prefer to stay away from the 4.3 bootloader because I want the ability to return my phone to stock for warranty purposes.
The OP is running 4.3 stock and the link you provided could brick his phone.

I never said that the OP needed to update his bootloader, I was just mentioning as an example if he wanted to then he would probably need to if he wanted to flash a KitKat ROM.
But you are right, for him, I would stay away from 4.3 since you can't downgrade.

[Q] Help Updating i747m to 4.3

Hello,
I am currently using a galaxy S3 i747m which is rooted and unlocked running 4.1.1. I believe I used this guide (http://forum.xda-developers.com/showthread.php?t=1739426) in order to do the root.
I want to update my phone to 4.3 while retaining the root (or rerooting afterwards). I've done plenty of research and haven't found a solid guide to help me. Most seem to assume I would be on 4.1.2 or already on a stock 4.3. I don't have a solid amount of confidence with these tasks so I'm too scared to just try and flash a 4.3 ROM without a confirmation that it will work. Kies tells me in can update the phone but I am also worried about that.
What is the best course of action for me? I wouldn't be writing here unless I had already done my research and was still unsure.
Also a side question, I'm not sure how the phone was unlocked (software or code), if it was unlocked via software, will I lose this by updating to 4.3?
Thanks for the help!
The easiest way to upgrade would be to use Odin to flash a pre-rooted ROM. However, you will lose your data and apps.

Thank you for the response! Do you know where I can get a good pre-rooted ROM? Would the 4.3 one in my previous link work? Would the Kies backup be sufficient in restoring my data? Or would I need to use something like Titanium Backup?
Thanks again for all the help!
Upgrading will not re-lock the phone.
You can use one of the pre-rooted 4.3 ROMs you linked. Personally, I stayed away from 4.3 as it will introduce Knox which may cause problems in the future.
I haven't used Kies for anything so I'm not sure how good it will work. Also, it's possible your apps may not work when restored under 4.3.

Thanks again for all the help. I went ahead with the update and it actually went better than expected. All my data was preserved including apps, media, settings etc. Its just now at 4.3 and rooted!

[Q] Downgrading CM11 to stock 4.3 on i747M

I know there are a few threads regarding this issue but I can't seem to find a definitive answer.
I am currently running stock 4.3 jellybean (rooted). My phone hasn't received the 4.4 KitKat update yet, so I wanted to install CM11 in order to get KitKat on my s3. However, I heard CM11 can be buggy on the s3, so in case things go south, I want to be able to revert back to the stock 4.3 rom. Some people have said that you can easily flash the stock ROM via ODIN. However, others said that downgrading from 4.4.2 to 4.3 will hard brick the device since installing CM11 updates the boot loader. So downgrading to 4.3 stock with a 4.4.2 boot loader will cause a hard brick according to other threads I've seen. My question is, how can I downgrade from CM11 to stock 4.3 safely without bricking? Thanks in advance.
If you are sure you are using a Canadian version of the i747m, you can flash back to stock in Odin using a stock 4.3 ROM for the phone's original carrier (Bell, Rogers, Telus).

Yes I got the phone from Rogers, it's most definitely i747M. But do I have to worry about any issues with the bootloader? I'm assuming installing CM11 will install the 4.4.2 bootloader, so if I choose to downgrade to the stock 4.3 rom, will it cause any issues seeing as I'm running a 4.3 rom with a 4.4.2 bootloader? I just want to make sure because I heard it can cause some serious problems if the bootloader is newer than the rom.

I have never come across a custom ROM that touches the bootloader. A compatible bootloader has to be loaded on the phone before you attempt to install the custom ROM. Supported bootloaders can be found in the ROM's updater script.
I assume your phone has no warranty since you rooted it on stock 4.3. Did you root it by installing a pre-rooted ROM?
You could copy a ROM to your external SD card, install Philz Touch via Odin, reboot directly to recovery, create a nandroid backup, wipe cache, Dalvik, data, and install your KK ROM.

Okay, I was just making sure because I know OTA updates can change the bootloader, so I just wanted to make sure the custom roms don't do that. As for the custom recovery, are you recommending Philz Touch over CWM and TWRP? Do you know which custom recovery is installed from the CM installer?

Oh and one more question, my phone was originally carrier locked to Rogers and unrooted on 4.3 jelly bean. I brought it in to a cell store for them to carrier unlock it for me, but they used a rooting method to unlock it (because SuperSU was installed on it when I brought it back). They didn't unlock it with a code, so I'm guessing they used something like Samsung Tool or z3x shell. If I install CM11, will I lose the unlock, considering it's more of a "soft unlock", or is the unlock permanent regardless of how many roms I flash? Thanks for your help!

Philz is based on the latest release of CWM and I prefer CWM over TWRP because I had problems flashing ROMs. Once I switched to Philz/CWM, no more problems.

The unlock should be permanent. I unlocked it using the free method when on 4.1.1 and no ROM has ever caused it to re-lock. Reflashing a completely stock ROM, including the bootloader, did not relock the phone.
Please remember that flashing and changing ROMs will always carry a risk of soft bricking or hard bricking your phone. Make sure you read all of the guides and be prepared for disaster.
