[Q] Note 3 N900W8 soft bricked, backup not working.. can't find a compatible firmware

I'm with Bell (Canada.) I was hesitant to root this device as it's a pretty significant investment, but I have rooted my original note with few issues, so I figured it should work as long as I follow every step carefully. Well unfortunately, upon first trying to root it, apps would start updating right at bootup, and SuperSU continuously crashed. So I decided I was just going to restore it to my original state and be done with it for now. Nope. Once I did this, the phone would just enter a boot cycle. (How does restoring my backup place me into a boot cycle?)
The only SM-N900W8 firmware downloads I can find are for south american regions... I have tried one of them and it failed to install. I am a bit panicked at the moment. Is there some crucial step I'm missing here?

I got an error message trying to flash a SAM firmware. It would just say FAILED in red letters. I'm going to try the Mexico one next, and hopefully it will work. I'm hoping someone could upload a working backup from their phone.

If you restored through TWRP there is a good chance that you are softbricked. There are restoring issues that mess with the system partition.

Update: I was able to flash the tar file from inside the zip of mexican firmware through odin (I was trying to install the zip through TWRM before... perhaps you need to install stock firmwares through odin? It's been a while.)
It's not rooted, and the icons are all different looking... but it's back in working condition

I am using the TCE (Mexican) firmware from this link (It won't let me post links since I'm a newly registered account on these forums, but if you google "n900w8 firmware site:samsungis.com" it will be the first result)
I unzipped the file and flashed the tar file within using odin.

You know what.. Me being a dumbass tried again to root it after restoring it to the mexican firmware, and now I have the same problem. And now the restore isn't working this time. Why did it work once and not again? Who knows? I just keep trying to factory reset and reflash the firmware, but I'm getting nothing but bootloops.

Could this be a Knox created problem? The reason I say this is you were able to restore a "new" (unknown to Knox) firmware, but it failed on the second time (as it is now no longer newer). I wonder if you were able to find a firmware with a later number (ex ...H2 rather than ...H1) it would install?

I'm wondering if the official Bell/Rogers firmware will be available any time soon? Does it typically get released soon after the phone launch, or are they withholding it for some reason?

I was trying the Peru one for a while, but it kept hanging up during the bootup. The message was in a foreign language, but I'm assuming it was "initializing". It would initialize for about 3 minutes then an error message would pop up saying something is not responding.

Did you try recovery factory reset right after Odin does the root and installs the files?

Well I have been trying to. When I flash the firmware in odin, it reinstalls the stock recovery mod. Right after flashing firmware, it won't go into recovery mode on the first boot (first does some android robot install thing, then boots up). I attempted to install the TWRP recovery directly after the firmware, and then booting directly into recovery to factory reset, but I'm still getting a boot loop.

How to downgrade firmware on Zenfone 2 Laser?

Hi, I am not happy with the latest update (V1.15.40.639) and would like to downgrade to the previous one (V1.13.40.496). I read on zentalk forum that we can downgrade by downloading the latter firmware from asus site(http://www.asus.com/Phone/ZenFone-2-Laser-ZE550KL/HelpDesk_Download/) and place it on SD card root. The reboot to the recovery and select something like "apply update from external". Can someone confirm if this will work? Is there an easy enough and confirmed way to downgrade the firmware. Any help will be much appreciated.
Edit: The method works!

Haven't done that but it should work, if you face any app crashes you will need to reset phone

Pls don't downgrade it will kill ur phone

Have you tried it? If it goes dead, do you think Asus service center will be able to revive it?

No but have heard that software cannot be downgraded in any phone

He is wrong xD
Like I said the you'd face app crashes which you can fix by resetting phone.
If you are not comfortable to do this then simply go to service center and tell them you want certain update flashed for whatever reason.

Did you actually go into recovery and flash the previous firmware or just let the phone detect the firmware and install it by itself?

I placed the update on sd card. Booted to recovery. cleared data and cache and applied the update via SD Card method. The cleared cache once more and rebooted.Voila!

This method is going to wipe all user data???

Probably a reboot would do the same result.
I have, like many others, the latest firmware and I didn't encounter no problems. So definitely is not the firmware itself.

LOL. That's one question I never ask. It's always a good idea to do a backup before any update, especially if it's a full firmware flash and not an OTA update.

No. I only wiped cache and it seems to have kept the data intact at the time. I had a backup for safety's sake but I did not need to restore it.

Can We root the phone after downgrading it to lollipop using Kingroot?

But if u Go from Marshmallow to Lollipop in ZOOL it won't do u any good moreover u would loose your VOLTE update

Hello,
Did you tried it ? 'Cause except for the security patch, i dont' think this update worth it, am i right ?

I think people who were in that version didn't got any update to B37x.
To my (limited) knowledge B180>B370 excluding betas.

in my case failed at 9% and I do not want to reset phone... staying at b180

Yes, the screenshot taken from my phone
@zinko_pt I got B371 update notification 1.18 GB in size.
@Ing.King really strange, i did it without any issue.
By the way guys, I just released it. It's up to you, updating or not..

We who had only B371 couldn't either update. Where and when will we get B30?

Really soo weird, I installed it at once without facing any problem.
It doesn't need a clean B180 rom because I installed it over my usual rom. It wasn't clean.
Something must be wrong in somewhere... but where?

Back here again..
No good news, tried to instal via sd, same issue, fail at 6%
But, but, but there might be a reason, i flashed the sdk21 of xposed, and idk how to remove it.. maybe this is the cause of it....
When you installed, you had to : unroot & put the recovery back ? Or you where "clean"
I'll try tomorrow, with a rest head

Oh, when I was saying "not clean" I meant installed apps and my all data
And yes, my rom was clean if we consider root and recovery condition.

Hi,
Hmmm so maybe the xposed package.rar i've flashed made this error
Well, i'll try when i receive the H8
Or maybe i had to put the recovery of B100 instead of B180 :/
Edit 1 : When i check the local.prop, there is "ro.dual.sim.phone=false" or the PLK-L01 is a dual sim, so i don't understand ^^
Edit 2 : Flash with TWRP =
MD5's missing

coming from B180 stock /rooted /xposed.....
1.) i flashed all possible partitions i had extracted (HuaweiExtractor) from B180. (system; cust; boot; recovery)
2.) reboot
3.) i flashed full rom B180 from folder dload (vol up&down&power) to be sure to get really all parts of firmware!
4.) reboot
5.) local update b190.zip from folder dload
6.) reboot
7.) i flashed twrp rc3 with fastboot to recovery partition
8.) had rooted and installed xposed now
all works as expected! Now i am on B190.
at least i had to install some modifications to system again and recover my data partition (twrp)
all in all nearly 1 hour hard work!

Hi,
In fact you just cleaned up your B180 in order to instal the 190 ?
The "real" B180
Pure stock if i could say ? Sure, it will work, but i tried to install it without getting back to stock^^

uff 1 hour to achieve upgrade... pity that I have to do factory reset to make upgrade to b190, no root no open bootloader no changes to firmware despite all this I cannot upgrade normal way... very sad, bad job honor(huawei)

because i had made a backup of my apps and data with the HUAWEI backup app (update to version from PlayStore is necessary!) recovery was easy! Had to remove some blood ware and unused apps only!
then reinstalled PMplus; managed autostart and apps they should stay on if screen is off.
reinstalled my google account
all in all a little bit more than 1 hour like i told you
now i am on b190 rooted; xposed and xprivacy activ on; and of curse Viper4Android for better sound.
real easy!

How did you update it? if you were rooted then you have to flash img files manually first before doing a three button update.

Yes, as B371 is the latest one so they will push B371 only, now there are no incrementals. But I have put up a thread here, maybe sometime later I'll post the OTAs too.

Just got n910t november n910tuvs2epk2 ota update in 60mb

Just got November ota update in 60mb i am just curious to know if it is gonna lock the bootloader.
UPDATE-/ BOOTLOADER STILL UNLOCKED I TESTED & DOWNGRADED TO 5.1.1 OK1 .

I just received it as well. I use my phone for work so it's encrypted but could you try to downgrade and let's us know what happened

Yes, you can still downgrade to 4.4.4 with the new update

This update should give me enough time to read the details of the update before it reboots my phone in the 25 seconds. At that point, we don't have the ability to "abort" or decline the agreement anyway.

Note 4 tmo, downloads the 60mb update, phone enters recovery mode then i get "update failed phone will recover the original configuration" .
I'm full stock, no root, no custom recovery no nothing. Anyone could help me?

I'd recommend you use the desktop version of ODIN with the latest FULL ROM to restore your device (without wiping) to the version before the OTA update. You can then try the update process again.

I encountered the same error last night. I held POWER + VOLUME DOWN to boot into Recovery mode, then I rebooted to System. My phone went through the app optimization process (you know, the screen that you'd see after wiping the Cache/Dalvik Cache).
I assumed that the update failed, but when I checked "About Device," I noticed that it now has the November 1, 2016 security patch (Baseband Version N910TUVS2EPK2).

I need to go back to Android 8, but I did the OTA update to Android Pie last weekend on my SM-G950FD.
Can I still flash the Android 8 ROM with Odin, without running into issues with the bootloader?
My current Baseband version is G950FXXU4DSBA and I want to go back to G950FXXS4CSB1.
Thanks in advance!

Yes you should be able to downgrade with the firmware you mentioned. As long as the bootloader version is the same or higher.( in your case 4 ).
You may have to do a clean install (CSC) or if using Home CSC then a factory reset from recovery.
Backup before doing anything first

... and is it possible to downgrade from DSBA to CRL3?
Thank you

I'm gonna try using CSC. Yesterday I tried it with Home_CSC, and the phone got stuck in a bootloop. I had to re-flash back to Android Pie to make it work again.
I'll update the thread to report how it went. Thanks!

According to this: https://www.sammobile.com/firmwares/galaxy-s8/SM-G950F/PHE/download/G950FXXU4CRL3, the bootloader is also level 4, so it should work.

It seems to me, though, that you were told to do a hard reset from recovery.
There should be no problem if Odin told you PASS.
link don't work.

I went back to Oreo CRL3 using CSC, the phone has reset to factory data ... everything is ok.

If you don't like pie I would turn off automatic system updates just in case it wants to update itself again.

Just tried the same yesterday with a 950F without any problem.

Everything worked fine :good: Had to use CSC, because HOME_CSC got my phone stuck in a bootloop. I'd rather not have to re-install everything, but at least the phone's back to working well under Oreo
Thanks again for the pointers!
