Hey Guys,
So, I've got an A8 2018 (jackpotlte) and currently have it rooted and TWRP installed.
I'd like to update the firmware using Odin to the latest version, but I don't want to lose my app setups etc. The firmware I want to flash is from the same CSC (EVR) that I have currently.
I've got a full TWRP backup incase anything goes wrong, and all data such as photos is backed up separately as well.
My question is, what do I need to do to get this update installed without losing my settings etc?
Will I need to reflash TWRP to the recovery after the update? And if so, I'm assuming I'll have to re-apply the no-verity and opt-encrypt patches?
Thanks for your help!
Last paragraph is correct.

Yes
You can try backing up apps and settings in Samsung Cloud.
Also, this app here may work for you. It keeps all your settings intact. Not sure how it'll work after an update, but I've used it while switching ROMS and if anything, it'll save you loads of time on your downloads after updating.

IF YOU FLASH STOCK FIRMWARE, YOU WILL LOSE ROOT. wITH THE NEWER FIRMWARE, YOU WILL HAVE TO USE THAT SPECIFIC VERSION OF THE FIRMWARES ROOT METHOD. yOU WILL HAVE TO FLASH THE csc TO DO WHAT YOURE WANTING TO DO, WHICH WILL FACTORY RESET.
Crap, all in caps. Im not gonna retype it, just know i wasnt yelling lol
there are app backup apps you can get like titanium backup that will restore most of your stuff including personalization.

I seriously thought you were angry. I was waiting for the part that... never came.
I re-tried the migrate app (also in zee store).
It's better than i remembered.
BUT IF YOU READ THE PREVIOUS POST, IT IS ALSO CORRECT. THERE. THAT SHOULD GIVE YOU PLENTY OF OPTIONS. (Couldn't help it).

Hi all,
So I've decided to root my Exynos International Galaxy Note 3 (SM-N900) using Chainfire's CF-Auto-Root. Problem is, Odin gets stuck at cache.img, then fails after a couple of minutes. Phone then displays BSOD whenever I try to boot. I can access download mode again, but not recovery. My phone is stock 4.2.2.
It's the first time I have such a problem, I flashed a couple of phones before without any trouble. I searched XDA for a solution and tried other Odin versions, different cable/ports, even tried on another computer, still doesn't work.
My first concern is not to lose any data as I didn't back anything up. Any help would be greatly appreciated. Feel free to ask about any missing info.
Thanks!
I see. It didn't say on the XDA thread it was only for Lollipop, but I checked in CF's website and you're right. I've wanted to update to LL ages ago but I didn't get it through OTA. The only LL release that's available for SM-N900 in SamMobile is Russian :/ I don't know if I should flash that one...
Would it be safe to flash back my stock 4.2.2 to at least get my phone back working? Or would the Russian release work for me (assuming it has language choice)?
Also, once I choose which ROM to use, would I loose my data when I flash it? I assume it is flashed the same way than root.
Thanks!
Hi, thank you for using XDA Assist. I assume you've seen this,http://forum.xda-developers.com/showthread.php?t=2466423. In regards to flashing a Rom you should always clear data, dalvic cache and cache before flashing. That will erase data so backup first. You should look into titanium backup on the play store.

Yes, that is the thread I've used to flash the root. Now I have a BSOD phone and need to fix it without losing data :/ I didn't back up so I guess flashing ROM is out of the question. Any suggestions ?

You're not going to like it, but you need to flash the stock firmware in Odin and lose your data. It's the only way to get your device working again.

I'm surprised. Can you at least explain why the root didn't work? I did everything as stated in the tutorial. I didn't expect a simple root operation would result in me losing everything on my phone; some data I cannot afford to lose.
Also, the phone says that using Kies in recovery mode is what should be done. Kies doesn't recognize the phone as needing repair. Any info?
Thanks !

Sorry, but live and learn. Always backup before doing any thing new on your phone. Especially rooting and flashing roms as they sometimes go wrong and rooting bypasses some of the safe guards the manufacture builds into the phone to avoid problems. Kies is crap. Learn to use Odin, if your rooting and roming you'll need it sooner or later. And you're at the sooner stage.
Edit, I'd really try asking your question here, http://forum.xda-developers.com/galaxy-note-3/help. I'm not sure on your device if you can go back to nb1, 4.4.4, firmware. I'm assuming there is no 5.x firmware for your device at this time. You can check at sammobile.com. But Samsung has updated the bootloader with each update and you have to flash the firmware with the same bootloader version. You can't go backwards.

SOLVED. I can't believe how easy it was. I was about to flash it over from scratch but then it struck me.
Chainfire ships Odin with all its root bundles, a version where you cannot untick "Auto Reboot". Because of Auto Reboot being ticked, Odin freezes at "cache.img". It might not freeze for some people but for me, having Auto Reboot activated causes the freeze
Downloading a different version of Odin (any version, I used 3.09) that allows changing parameters and LEAVING EVERYTHING UNTICKED BUT F. RESET TIME works like a charm.
Don't forget to reboot your phone after Odin displays PASS or RESET (Long press power).
I'm going to PM Chainfire about this, and tell a max of people about it.
Thank you for your support
EDIT: Also going to NANDroid my phone. I'm tired of panicking over failed roots
Does anyone know where I can get just the stock bootloader image to flash via TWRP?
Long story short I F'd up my bootloader and now Odin will not flash a stock BL file do to a version mismatch and to make matters worse I can't find a way to restore to stock baseband so my network isn't working. If someone can share a backup that'd be super
EDIT: Forgot to specify I need it from a TMobile variant (J700T) for firmware APK6 or APK3 (Odin doesn't seem to want to flash the stock BL from my Odin ROMs perhaps because there is a version mismatch in the phone?)

download latest stock rom at sammy..
Already tried. Looks like I am officially a victim of a partial brick (Odin wont flash BL because it thinks I'm downgrading and I have no Baseband/network) I'll try and see what I can do through TWRP since I can still flash that through Download mode. I made no backups myself but would restoring another TWRP backup solve it perhaps?

No dice my dude. However, I did find something else
Turns out when I check the bootloader version it reads J700T1UVU3AQC3. Sure enough there was a baseband update and security update a few days ago and my device must've installed it while I was asleep. This would explain why my baseband is broken AND why Odin doesn't want me to flash the APK6 Bootloader.
So there's good news and bad news. The good news is there is hope but the bad news is I am currently at the mercy of whenever someone decides to upload this firmware on the internet (if anyone does that is)

You are lucky because you at least have a functioning bootloader and a working TWRP. You are unlucky because AQC3 firmware is not available publicly yet. In any case, bootloader cannot be flashed in TWRP as far as I know. Your only option is to get your missing ACQ3 partitions from someone else's back up. IF you have messed up your EFS partition though you are out of luck.
So exactly what partitions do you need? I may be able to give you those partitions if I have a personal backup of those from the past. Right now I have modified so many things that a current copy of my partitions will probably do you more harm than good.

As far as I know I just need a main system.img backup
Edit; to specify, if I was flashing with Odin it would be what I would put in the AP slot
The phone in its current state is extremely slow and buggy. My intuition tells me that the older Android version does NOT like the new fiirmware (The bootloader is also where the firmware/device config info is stored IIRC)

Well lucky me Ive got a similar situation though I reflashed with a 3-part HOME file from sammobile to unroot/unTWRP, but did so not realizing the darn BL wasnt included. Lucky for me my build versions matched, so Odin flashed flawlessly, the device boots as if it were brand new, stock recovery and all, everything functions/boots as it should, splash, factory setup, TMobile network works fine etc - only problem is both SafetyNet tests fail, so Google wont let me use use Android Pay and every other payment app that hooks into their API shuts me out. I also noticed a lightning-fast error right before going into the bootloader if you boot from the stock recovery (its so fast I need to capture the log to see what it is).
Any suggestions on where to find a BL to go with my J700T & assuming I find one, any nuances I should be aware of when flashing so as to avoid a potential brick situation?
FYI I flashed with the below from sammobile (and yes I was already at AQF1).

The bootloader is always included with the firmware and is most certainly included with the firmware you posted.
Safetynet probably fails because you need to factory reset.
I am using S8+ Exynos G955FD. So guys I have done rooting, flashing on samsung and other phones before. Can someone guide me about how to root this device. My phone has been on for more than 7 days so oem unlock is enabled. Build number is R16NW.G955FXXS4CRIA
I tried searching but those threads were more than a year old.

Try this thread it is a bit more up to date. It includes info about RMM state and has a link to the latest zip file. As for rooting I would suggest using magisk.
Also use:
Latest Odin 3.13.1
Latest twrp 3.2.3.2 for the s8+
Latest no-verity-,opt- encrypt ver 6.0
As for the data wiping issue it is necessary to format data in twrp . For backing up apps/data you could try smart switch or an app from playstore. I generally use twrp for my backups but I do have titanium backup as well but it does require root.

Hi Mustafa,
Helium does not backup all apps data (some yes and some no)
Smart switch does not backup any apps data (only backup and restore the apps without the data)
so how you managed this (Smart Switch for backup and restore data) or you mean the apps without its data (settings and games levels)?
Which steps and files exactly you used to root? did you wipe every data on phone?
Hi, I recently came across a thread via the Samsung members app that talked about the "ONE UI" update and how to install it on s8 plus devices that end with a "W" (by CHMultimédia) (canadian variant) model code. I was wondering if anyone here has tried the method, and if so, are there any issues? bugs? How does this compare to the method already on XDA? and does this reduce battery to 80% like rooting?
Thanks
I use the G955U U1 firmware on my G955W. I don't really have any problems. Charges to 100% etc and I have the added bonus of now having the FM radio chip activated (which Bell lies about and says only Samsung can enable it).

Sorry to bug you again, However I have a question in regards to restoring to stock. I'm slightly puzzled as to how to backup the required files in order to keep them to be able to revert to stock when needed, and also I do not understand how to even begin the process. I've rooted my fair share of phones, however with the s8+ everything is really quite new to me. (Currently my s8 G955W is completely stock, no root, no nothing).

I basically do three backups (I believe in redundancy). I first backup with Superbackup Pro. With it I can backup sms, call logs, calendars, contacts and even apps. The second and third backups are done automatically but I make them do a backup NOW. These are under Settings/Cloud and accounts. First I backup to Samsungs's Cloud. I make sure everything I want backed up is turned on, then do a Sync Now. Next I back out of Samsung Cloud and pick Backup and Restore. Again there I make sure everything is turned on (except music for me as I'd fill my space too quickly. My music is backed up on my computer anyway). Lastly I pick Backup account from my Google Account. and pick "Back up now". With this I should have a good backup of everything I want.
Hope this helps.

I see, that makes sense. However, is there a way to backup the bootloader or the rom? I don't mind losing all my files however, I would like to keep my rom/bootloader just in case I screw up during the update to android 9.0 process or when I decide to revert back

OOO, thats really helpful! Thank you . Now that I know where to find the files, I have no fear of not being able to revert back to stock! Though I have a slight question, looking at the website there seems to be a lot of different versions, I have an unlocked s8+ with G955WVLS5BSA1, my question is since i've an unlocked variant, which file would you recommend I use in case I ever need to revert to stock? and also because my bootloader is G955WVLS5BSA1 with the CSC ver G955WOYA5BSA1 is it still possible to update to android 9.0 using this method?

You don't seem to know a lot about flashing (my impression but I could be wrong as this is text only and not person to person) Things can go wrong very quickly and you risk bricking your phone. Basically your process is to flash a US version back to CK1 (T-Mobile is the best), then do the updates as per the link you provided. THEN if you don't like the beta, you have to flash back to stock per the link I provided. Either way, in the end, you will have to flash back to stock when the official version comes out as there will NOT be a way to upgrade from the beta to the official version. Personally, I would wait till the official version comes out. It should be this month. In fact, I personally didn't like the beta version so I've flashed back to stock and will wait for the official version.

I use the G955U U1 firmware on my G955W. I don't really have any problems. Charges to 100% etc and I have the added bonus of now having the FM radio chip activated (which Bell lies about and says only Samsung can enable it).

I've never flashed a cellphone and I don't even know if I can flash this one. I bought the phone through and when I was still with Sprint. I was told flashing it might be tricky if not impossible since I bought it through a carrier and was also told to come here and ask. So that's what I am doing. Thanks for any help!
Even you haven't said what you want to flash and why (mean what you want to achieve with flashing)

As above, what do you want to achieve by flashing it, and what do you want to flash to it?

I'm sorry. It was a little late at night and I was trying to put the child down for sleep and was in a hurry. But I'm looking to just flash a stock ROM to get the vendors (Sprint) pre-installed apps off the phone. So I'm not looking to do anything to fancy.
Try flashing non vendor specific rom. But before that simply keep copy of rom which is installed currently, so in case something went wrong, you can restore it.
You can download stock firmware with friza or Sam firmware tool (little search over xda you can find it)
Okay, so I used Frija to get the file and now I'm using Odin to flash it. I have the BL, Ap, Cp, CSC, and USERDATA files. Only issue I have is I have two CSC files and I'm not sure which one to use? One is called HOME_CSC_OMC_OYN_N986UOYN1DUB5_CL20936746_QB38027387_REV00_user_low_ship_MULTI_CERT.tar.md5 and the other is CSC_OMC_OYN_N986UOYN1DUB5_CL20936746_QB38027387_REV00_user_low_ship_MULTI_CERT.tar.md5. I want to say it's the second one I mentioned but I want to make sure.
Home_CSC* won't delete your data while CSC_* will do.

What data is the Home file saving? Also what's the USERDATA file?
All other data that you have addled other than factory set.
Some apps install as non system, that known as userdata
Okay, Odin said it passed and my phone restarted to a Android Recovery section giving me a ton of options and now I'm nervous... The options are.
Reboot system now
Reboot to bootloader
Apply update from ADB
Apply update from SD card
Wipe data/factory rest
Wipe cache partition
Mount /system
View recovery logs
Run graphics test
Run locale test
Power off
Repair apps
Do I just want to reboot it?
Okay so I restarted it and the phone works, but everything is still the same. If I do a factory restore will that remove Sprint's apps? Or should I redo the process without adding the CSC and USERDATA files?
Sorry for bumping this but does anybody know the answer to my question?

From what I remember once you flash an unlocked firmware (ie. Not carrier branded) you need to factory reset to remove the carrier stuff from the old firmware
But don't quote me on it, just what I remember reading from others threads, I've not had to try it myself

Sounds good. I'll try it when I get home later and am more prepared and report back. Thanks for the help so far everyone!

You can kill 2 birds by using CSC instead of HOME_CSC when you flash the firmware, that initiates a factory reset after the flash (ie. Clean install)

Actually I might just do that then tonight.
Unfortunately, it didn't work... Not sure if I did something wrong but Sprint's app's are still on there.

Which ROM you have downloaded?
If you are flashing same sprint then it will always remain there. Make sure you are flashing unbranded firmware.
