Does anyone know if it'd be safe to downgrade from S916BXXS1AWBM to S916BXXU1AWA6 ?
It's on the same bootloader so it's safe to do so, make sure to backup your data using Samsung smart switch first as downgrading will require a factory reset
Looks like that worked, thanks man!

Hi guys, sorry in advance for my silly question, I have just installed a factory ROM on my LG E900 (optimus 7) and have the version 7.0.7004.0... after that I have unlocked the phone usind the phones registry editor (not chevron) and I think everything went well (no errors)... but after all that I made a factory reset on the phone, now my question is: do I need to unlock it again after factory reset or it remained unlock anyway? Thanks in advance for any assistance and for your pacience as well.
What do you mean by factory reset?
Also there is one easy way to test - try sideload an application.
I would imagine that a reset would set your phone back to the way it was when you got it / after flashing it.

Hello,
I'm not new to Android but I just crashed my G2 and bought a Z3, so I'm new to Sony.
I have a D6603 running 23.1.A.0.690 with a stock locked bootloader.
I would like to root my device without loosing my data. Is this possible ? I'm not sure I completely got what I should do, could anyone please provide me with some guidance ?
Thanks in advance.

Not if you do not flash data and choose not to wipe data partition.
You will get a lot of FC's which may make it awkward to go through the rooting process, but I believe some people have managed it.
Root D6603 on .77 by downgrade, no data wipe
Thank you for your quick reply. I'll download everything and try this by tomorrow morning.
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.

I will, thank you. I can't afford losing anything as of now. Really hope there's a way of getting it to boot back up.

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
Hi there!
My brother has a Z5 which he has been using for quite some time. Recently he's been wanting to root it and he's asked me to do it. From what I understand, since he's on MM, I'll need to downgrade his firmware to backup DRM files and unlock the bootloader and such, and this process will involve erasing all his data. My question is, is there any way to root without losing data, or failing that, is there any way to back up his apps/app data/conversations/contacts/etc prior to the process? TB doesn't seem to work without root. I noticed there was a built-in Xperia backup tool but I was unsure how good a job this did at backing up all app data and such. Thanks!
Have you tried Kingroot. Just downgrade to ? with flash tool and try Kingroot.

From the flashing I've done, in order to downgrade to LP, you're going to have to wipe all partitions to get the device to boot. You can try downgrading the firmware without wiping anything, but when I tried that I ended up stuck in a bootloop and the only way to resolve it was to flash the LP firmware and wipe everything.
So the short answer you're going to need to figure out a way to backup the data before you try to downgrade the firmware. That said, there is a tool that will backup the TA on firmware before the November patch, maybe you should try that first. Once you decide to unlock the bootloader, it will wipe all data so again, see if you can figure out a way to backup data before unlocking the bootloader.
Is there some data in particular you're trying to backup? A lot of stuff is saved to the cloud or there are other backup apps that might be able to backup certain data.
EDIT: Have you looked at Helium? I've never used it but it might be able to do what you're looking for.
Hi, I have forgot my password for unlocking the phone and now I need help because I dont want to restore it and loosing all the data (pictures and so on). Is there any way, please helpp
I think the only solution is to factory reset from recovery, if you can do that.
SORRY.. i think factory reset is the only way..
also i heard another way which requires twrp to be installed , but i dont recomend it, bcause it caused some serious problems to some ppl..
Do you maybe know if there is any possibility for me to recover the lost photos after?

Unlocking the boot loader to flash TWRP wipes the phone. Factory reset wipes the phone. Bottom line don't forget the password

Yeah sadly with Android 5.0+ you need root to get rid of any lockscreen security. The only way is to factory reset if you want to remove it. But sadly as mentioned rooting would wipe the phone since you have to unlock the bootloader.

it's good if you think about it ... what if a stranger wanted to get your photo's txt and contacts ?
that's the whole point in having the password in the first place
