Can you flash stock firmware on the G4? - G4 Q&A, Help & Troubleshooting

I remember following the correct flashing method on the G3 to install stock firmware but it would always boot back up with the Vodafone splash screen, even after flashing generic firmware. I don't want to root or unlock the bootloader as my firmware is very 'stock'; though if I can easily do this - as with ODIN on the S5 - then I might as well.
There is a flashing guide on here but it just says 'return to stock'. It doesn't say anything about MOVING to stock from a branded firmware, unless I'm missing something.
Thanks in advance.

[Q] Create official odin image? Or: firmware for drei.at?

Hi.
I got a note 2 and would like to have an odin image with the official state as I bought it before I start tinkering with it (root, flashing rom, etc) so I can restore it if I need to claim warranty service.
The issue is: The firmware is of the austrian mobile operator 3 (www.drei.at) and I did not find an official firmware for it!
Can someone point me to it if it exists (did not find it on http://www.sammobile.com/firmware)?
Else: Is it possible to create an "official" system dump of it that works with odin? So if I restore from that created firmware it restores to the state I bought it without anything changed (no custom firmware counter increased, etc).?
I know there are some guides on how to create odin dumps, but they are rather complicated and I am unclear if I restore from one of those if it counts it as official (does it need to be signed for that and anyone not from samsung even do that?) and does not increase it.
Can you help me?

You can root your phone and do whatever you want, and whenever you want. You can simply return to official warranty version by following steps in first reply of the link i attached.
Thanks
I don't think you get want I mean:
I know how rooting and flashing and odin works, i've done it lots of times. And i've also returned phones to stock.
Until now however I always had unlocked devices with completely official samsung firmwares, but now I have an oparator specific firmware: that of 3 austria.
I did not find an image for this firmware, so I cannot flash back the correct stock image because I did not find that specific image provided anywhere.
So my question:
- Where do I get the firmware JRO03C.N7100XXALIJ for 3 austria? Is it even available?
- If not: can I create it myself?
On http://www.sammobile.com/firmware the only option sensible that gives me results is the latest 10...
Is there a way to view all firmwares for a device (i.e.: n7100) to make sure mine is not among them?
this site is much better. you won't find that firmware exactly but you find other updates for your specific region!

I already regret trying to add custom ROM.

Hello,
I tried to flash custom ROM, but something somewhere went terribly wrong.
I did read some guides on flashing before attempting this and did make some precutions as well.
Such as creating ROM backup with CWM and copying efs folder with Root browser.
Unfortunately I didn't succeed with the flash. Now the phone can turn on, but there is no network service, and IMEI number is missing.
I tried to go back to my original ROM, but that didn't fix the problem.
I tried to gather as much information as possible, but it seems that information on this device is a bit outdated. For example, I wanted to try to flash back to stock ROM with odin, but most links with stock ROM are down. The one that isn't down only provides .7z file instead of md5,tar file that is required by odin.
The device works, just can't connect to mobile network.
Is there something I could do?
Before flashing anything else, what baseband and bootloader is on the phone? The imei may be missing because the ROM is too new for the phone's current bootloader/modem combination.
Bootloader version is T999UVDLJA
Baseband version is UKNKOWN
I have finally found stock ROM in tar.md5 format, which is compatible with ODIN.
The t999 is the aws version of the s3 according to this: http://www.gsmarena.com/samsung_galaxy_s_iii_t999-4804.php
This forum is for the i747 and i747m (the AT&T and Rogers) version of the s3.
If the t999 is like the i747, do not flash any ROM via Odin that tries to downgrade the bootloader as this may brick the phone.
This makes just even more complicated.
When I go to settings -> About device, under model number I have SGH-I747.
When I double check this with Samsung phone info app, under model number I have SGH-I747.
In the same Samsung phone info app under PDA version I have I747UCDLK3 and under CSC version I have I747ATTDLK3
t999 only appears when I enter Download mode via volume down + home button + power button.
What does the label under the battery say about the model #?
Label under the phone is SGHT999.
Wow, this phone is weird...
I read on the forums that there is chance to restore firmware of the phone with KIES, so I tried that. At first I entered SGH-I747 model number and serial number of the phone and it failed. But after that I entered SGH-T999 model number and serial number of the phone and KIES started to update the phone.
At the moment I have android V4.3
Bootloader T999UVUENC2
Baseband T999UVUENC2
PDA version T999UVUENC2
CSC version T999MBENC2
Phone seems to be unrooted, IMEI number is visible, I can call again, but the phone's factory mode is on.
It seems that I had a SGH-T999 which somehow was tricked int thinking that it is SGH-I747.
At the moment I would just like to have a stock ROM for this phone without all the T-Mobile apps, would that be possible?
Does everything see to work?
The easiest way to root and remove apps would be to flash a custom recovery, install supersu and titanium backup. Then use titanium backup to remove the apps.
Yes, at the moment everything works.
I can call, receive sms, use wi-fi as well as mobile data.
The only problem is that phone has factory mode on Yellow text on black background. And it is heavily loaded with T-Mobile applications.
So I guess this phone is T999 then, right? How could it be that everywhere it had I747?
By custom recovery you mean custom ROM?
You need a custom recovery such as TWRP: http://forum.xda-developers.com/showthread.php?t=1809313
Download the tar version that can be flashed via Odin.
Download supersu and copy it to the phone. Flash recovery, boot directly into recovery without letting the phone boot the ROM, flash supersu, reboot. Install Titanium Backup from the Play store, remove the apps.
Thank you for sticking with me in this thread!
Could you please explain a little bit more what is TWRP? From the link provided I understand that is is a application that helps with custom rom flashing and backing up roms?
Shouldn't I do this at first - http://forum.xda-developers.com/showthread.php?t=1771687
Boot into download mode. Do you see anything about warranty bit 1? If you do, that means you have already tripped the counter.
Root is not required to flash a custom recovery.
If you are only interested in root, follow the other thread. If you want to be able to flash custom ROMs and backup the rom, you need a custom recovery which will definitely trip the counter.
Do you have any warranty left on the phone?
Yes, there is 1 next to warranty bit. What does it mean for me that I have tripped the counter?
At the moment I would just like to get rid of factory mode and remove those unwanted T-mobile APPS. I think I will be done with Flashing for quite some time
I don't have any warranty on the phone, It has been in the family for quite some time.
It would be 0 if the counter wasn't tripped.
To bring it right back to stock, you could flash one of the prerooted ROMs from the other thread. Just make sure you are flashing a rom that has the same bootloader that is currently on your phone. Hopefully, the stock rom will remove the factory mode.
I understand that the counter is only important if you need warranty, yes?
I actually just found a way how to remove the factory so that is one more thing less to worry about
And I rooted the phone with odin using the link few posts back.
Now for the final question, I understand that this rom is something along the lines that I'm looking for? http://forum.xda-developers.com/showthread.php?t=2501303
The ROM looks nice as long as you are running the correct bootloader and modem.
Installing a custom ROM only requires a custom recovery. There is no need to root or remove apps from the existing ROM since you are going to wipe the existing ROM before installing the new ROM.
I read through the thread and I understand that I have to flash T999UVUEMJC modem before flashing the ROM.
I'm not sure where the bootlaoder of this rom is mentioned. Only place where boot loader of my device T999UVUENC2 is mentioned is in change log "-Rebased to T999UVUENC2".
The official T-mobile firmware is here: http://www.sammobile.com/firmwares/database/SGH-T999/
Notice the last few letters in the firmware PDA?
Based on your post on the first page (post #7) you are on the NC2 bootloader and modem, which are compatible with the rom you are wanting to flash. (See the second line under the Disclaimer banner.) NC2 is the most current firmware for the T999 listed on the page Audit linked to.
(one explanation for how your device was reporting i747)
Is it possible that someone else flashed the i747 rom to this phone? Either someone doing you a favor or a previous owner? I747 roms will work on the T999, I frequently see people commenting on doing so successfully. You just need to have comparable bootloaders and modems. That and if the rom dev didn't accommodate the device in the updater-script the user must edit the script himself. In the unofficial cm12.1 thread for the i747 people were doing this often.
So the bootloader version is always the same as the modem version?
I understand that in my case I don't need to flash T999UVUEMJC modem, since the one I have at the moment is newer?
That is definitely possible, although, how it came to be I will never know, since I personally didn't buy the phone. But this would explain a lot.
Could you please take a look at this thread, I created steps I plan to do in order to flash the above mentioned ROM. It would really put my heart at ease http://forum.xda-developers.com/galaxy-s3-t-mobile/help/one-rom-flashes-please-double-check-t3111443

Please identify my SM-T705 build!!!

Hi there,
I have the Samsung Galaxy Tab S 8.4 LTE version, which I purchased through Ebay - I believe it came from Asia somewhere as it showed up with an international adapter for the power supply. It was sold as a "Verizon" model - I ditched that sim card and have been using it with Bell Mobility in Canada.
Recently, I tried to update my firmware using the latest version of Samsung Kies and I'm running Windows 10 latest version. For some reason Kies needs to reinstall the USB driver before performing the update to the firmware and this causes Windows 10 to crash without fail. (This is also happening to my Note 3 - Samsung informs me Kies is not compatible with Windows 10 although it seems to work for everything else - just not the update). Kies doesn't seem to care that I already have the latest drivers installed.
I can't update via the tablet because my device has been "modified" - rooted.
Finally I went to Sammobile for the firmware, however I can't find any US firmware for a compatible carrier under SM-T705. I am debating flashing the Bell Canada firmware, but the model is listed as SM-T705W. In case this is not ok and I need to revert to the original, I'm hoping someone can help me identify my build? The samsung agent offered to identify it but once she discovered it was from outside Canada she said she had no information. So much for Samsung International!
Please help! I'm having battery issues and I'm hoping updated firmware will help, plus I would like to have the latest version of Android. Thanks!
If you're in Canada then just flash the Canadian firmware.

Hi there, forgive me for being thick, but how do you tell it's Cellular south, and what do you mean by region XAR? I'm sure that the fellow I bought this unit from flashed US firmware, however I can't find it on the Sammobile site - in fact I can't find any US carrier firmware listed for this model.
As mentioned above, I did find Bell mobility (Canada) firmware listed for the SM-T705W but nothing for the SM-T705.
Further explanation greatly appreciated!

You can flash any firmware for that model, so just flash the Canadian firmware, no point in flashing a us firmware.

Ok great. I would like to locate the US firmware though for future use. I travel alot in the US and in the event I need a different carrier's modem... Are the US carriers listed somewhere else or am I blind? http://www.sammobile.com/firmwares/search/SM-T705/
Thanks!

You have root so install twrp from the development section and do a full back up of your current system.
You can then restore as you please.
Seems no US firmware for the t705.

LOL... ok now I have another problem. I had already downloaded the Bell mobility file from Sammobile and hadn't seen this response - in the meantime I hooked up with Odin and my download failed twice - I don't get it. I just did my Note 3 10 minutes ago without any issues. Rebooted device and odin between both attempts.
Thoughts?
Don't flash anything until you make that full backup with TWRP, trust me it will save a massive headache should you need it.
Download Flashfire from the link below then set your date back to August, run Flashfire then load up the firmware, select the Flash firmware package option.
From the partitions list select system.img and boot.img only.
Under the reboot options select download mode then hit the flash button.
Once it has flashed and booted to download mode you will need to flash a lollipop bootloader (assuming you are flashing lollipop?)
You will find them in the bootloader thread.
After that just reboot the tablet, it will take about ten minutes for it to fully boot.

Uh... ok you lost me early on. I downloaded the file - how do I install it? I remember using the TWRP thing several phones back when I was messing with custom ROMs. I had a problem with recovery and since then have never gone this route - I've been happy with stock rom and root - installed using Odin... sortof the KISS principle.
I can try TWRP, but could you dumb down the instructions a bit - as I mentioned, I'm a bit thick - particularly with some of the terminology! LOL
This is the file I downloaded - yes, Lollipop - I don't understand why I have the Odin Fail - google isn't helping me understand either. I have root, USB debugging is enabled and I followed the same steps as with my Note 3 - the message said write fail.
http://www.sammobile.com/firmwares/download/52301/T705WVLU2BOE4_T705WOYA2BOE4_BMC/ Is this what you mean by bootloader?

Ok but those "bootloaders" are custom ROMS are they not? And I don't see my device on the TWRP site - I have the LTE version, it only shows Wifi.
Really all I want to install the Bell stock firmware (assuming it is indeed compatible - SM-T705 vs SM-T75W) I linked to from the Sammobile site and then do Chainfire's auto-root.
Why isn't Odin writing the firmware to my device? I've never had this issue before and I don't see what I might have done differently with this device - it's the first time I've tried to update it, but I had no trouble rooting it with the chainfire auto-root.

No they are bootloaders they are required to boot the firmware , roms are the os.
Odin won't flash because certain devices will refuse to flash another regions firmware.
My advice to you is to flash the lollipop bootloader first, to make sure it will flash then flash the firmware with flashfire.
Obviously make the twrp backup first.

Ok I flashed the bootloader, and then I tried to flash the firmware with Odin again but it still won't do it - write fail again. I've never used flashfire - windows 10 won't open it...
UDATE: Ok I read to transfer the file to the download folder on the tablet, and then install on tablet. So I did that, but when I click on the icon it doesn't run. How the heck do I use this to install the firmware update?
Figured out the date bit, ran Flashfire.... problems during the install - got stuck in boot loop - tried a factory reset - that didn't work... stuck in loop. I think I'm bricked....
Left the default settings in place - very little in the way of instructions - read the bit about not trying to write over protected settings...
And got this:
You're not bricked as long as the tablet starts up and you can boot to Download mode.
I've seen that error with corrupt downloads so not sure why you're getting it.
Reboot to download mode. Just hold POWER + HOME + VOL DOWN until the device restarts and boots to download mode.
Doesn't matter if it's boot looping.
Reflash TWRP and restore the backup you made earlier. You will be back to where you started.
At this point I think the best option is to flash a custom lollipop rom.
There is a very good one I use on my t805 which is practically stock with a bit of bloatware removed.
Its in the development section called sweetrom.
At least one positive is that you were able to flash the lollipop bootloader, so upgrade is not impossible.
I'm definitely able to get to download mode - I was surprised that the factory recovery mode didn't work. I'm wondering if the file from sammobile is corrupted - I used the same file with Flashfire - now I think Odin was trying to save me. I'm downloading the same file again fresh, and it looks like Telus and possibly the other Canadian variants are the same - unless it's the same corrupted file.
I just hope the problem isn't because my phone identifies itself as a straight SM-T705. That is why I asked about that point earlier. There are plenty of straight 1705 options available - just don't know which country would be compatible - particularly for the modem.
I didn't understand how to use TWRP and I've had problems with it in the past (recovery) when I did figure out how to use it and was messing with custom ROMS a couple of years ago. I would really like to get myself back in order with a proper stock ROM and root. This tablet belongs in my car and right now I just want it to work properly - I'm using Torque to resolve some ongoing engine issues and it will suck if I have to go back to using the small screen on my Note 3.
If there is any way to figure out which of those countries for the 705 are compatible with Canadian carriers, in case this Bell firmware is defunct, that would be appreciated.
As well, is that bootloader going to cause any problems with stock firmware? I've already flashed it - does stock firmware come with bootloaders included?
OK before I go any further with this I need you to install twrp and make that back up. Twrp is now very stable.
Twrp will back up some very important partitions namely the Efs and modem. Don't take this warning lightly. The amount of people that have soft bricked their device because they didn't do this.
Boot into twrp then simply select the backup option and make sure the partitions on the left are ticked particularly boot,
Efs and modem.
Now as regards which firmware.
I would forget about installing the Canadian firmware.
It looks like this firmware will only install specifically on a Canadian device.
It doesn't really matter which firmware from which region you install as they are pretty much all the same except for the carrier ones which just add more bloat and some csc specific stuff.
Just go for an international rom. You've already flashed a bootloader from one of these roms so that proves you can flash.
Use odin to flash.
If you have connection issues afterwards then all you need do is restore your modem backup with TWRP.
That's why it's important you do this.
Follow these instructions and we will get you up and running.
Whole again!
Whole again!
For the record, I read elsewhere that it is NOT recommended to flash other letter variants of a model. In the meantime I downloaded all four Sammobile Canadian Carrier files and they appear to be the exact same file and all install attempts failed For anyone else with an actual SM-705W I read in this thread: http://forum.xda-developers.com/galaxy-tab-s/general/t705-lollipop-t3099945 a fellow Canadian was having a problem with those same files. Dunno what happened with him in the end, however I tried one more W file I found elsewhere that appeared to be different but it failed as well.
Based on the comments in the above thread, I flashed the Hong Kong variant for the SM-705 from Sammobile - apparently it was the first firmware widely available and users from several countries posted they had used it successfully. So far it seems to be working ok - after flashing it, I did a factory reset on the device as was also recommended in the above thread. Sure hope the battery life will be better than before - love this tablet but I've never seen a device drain so rapidly! CF-Auto Root restored!
As a side note my Ebay seller did reply to my origins query and was helpful once he realized I wasn't complaining about the device and wanting to return it... LOL. Apparently my unit originated in Singapore and arrived with that firmware along with a Verizon SIM which I never tested. As long as the OS is smooth, and the modem compatible, and unless someone advises a better country variant, I guess I'll stick with this one.
Now just need to get Torque reconfigured!

S3 ATT Like to know how to unlock bootloader, root the phone, and install custom ROM

Hey first time posting on xda devs and would like to know how to unlock bootloader, root the phone, and install custom ROM.
Now I have spent entire day backing up and searching the different people root but if someone can help me and point me in the right direction that would be great.
So I have a S3 from ATT Model: SGH-I747, Version: 4.1.2 JellyBean, BaseBand Version: I747UCDMG2, Kernel: 3.0.31 - 1300972. It is a stock ROM, I have never done anything to the phone at all before.
Now I will admit I followed a youtube video call "How to Root AT&T Galaxy S3 SGH-I747!" by High on Android and I did everything in the video. I used odin v1.85, I did the PDA to the CWM.tar file, phone rebooted and I added the CWM superuser file and that is when I tried to get to CWM recovery mode and all I got was the phone's default recovery mode and not the CWM one.
From what I understand I believe I need to unlock bootloader first, but again this is a my first doing this and I hoping someone can point me in the right direction. Forum post state that you should follow guides that is exactly the same to the phone you would like to install custom ROMs.
Honestly I would like to ultimately be able to install a recovery mode that works with my phone that I am able to create snapshot image of my stock phone in case anything happens or I would like to go back to my stock image (which I highly doubt if everything goes fine) and install a custom ROM (I know there are different ROMs if someone can point me to where I can check out all the custom ROMs and not necessarily install those custom ROMs that would be awesome) and finally get rid of ATT loading screen when booting up the phone and install a custom boot loading screen, but of course I care more about getting the custom ROM install first.
If anyone can help that would be great.
The bootloader is not locked and using any app or program to unlock the bootloader will probably brick the phone.
The phones bootloader is already unlocked. Only verision s3 has a locked bootloader. Also you need to be in download mode for odin to work

Question Flash S21 FE (MetroPCS/TMO) to ATT

Can I flash this variant (SM-G990U) over to the ATT, or even a stock unlocked firmware?
The goals are to enable WiFi calling, and remove the metro splash screen.
I cannot root the device as my work requires official firmware.
I am open to suggestions on what is best. I have not tinkered with flashing in quite some time.
U could try to root phone and use safynet fix if your apps requie official firmware non root. if you have (when i check model) standard S21FE phone with branding from ATT (?) you could flash stock rom with odin. I don't know where u from but you could flash your stock firmware for example for spain distribution.
I was able to flash the phone with stock firmware, changed csc to ATT and all works well now. This place has gone downhill. I remember when almost immediate replies to help. Now, not so much. Thanks for trying.
