I actually had bought my note 20 Ultra that was stuck in demo mode then after getting it out of demo mode found out it was blacklisted. Had to get IMEI changed. Now everything works yet i have similar problem regarding android security/firmware updates. Oden was used to fix it so that it works, yet I'm not rooted nor did Knox get tripped, & the device comes up as official. I'm running 11 on 3.1ui & would like to upgrade to 12 as you on 4.0 or 4.1. I Believe all i need to do is flash the new firmware via Oden or bootloader, but I'm not entirely sure if same applies to you. -S.

Your not gonna get much help here with a black listed device. We do not condone imei changing and such either. Your best bet is gonna be looking off site

Neither do I nor was I implying to do such a thing. I just didn't have a choice after getting screwed for almost a G$ online. I just added that in due to me having similar experiences with a device that was not only locked in Demo mode soon arrival but then found to be a thousand dollar paper weight. For I got double slapped!
Aside from that. Perhaps you could point me in the right direction in terms of how to get proper updates.

P8Max DAV-703L rollback to Android 5

Hello,
I recently "upgraded" to Android 6 and I hate it. Not only do I not like it but my phone is very unstable and reboots and random intervals. Battery drain is also insane, lasting only 1 day.
Please let me know how to rollback to previous Android version. I am willing to donate for an answer that works.
Thanks!

1: make sure you have stock recoveries in place (both "recovery" & "recovery2" partitions)
2: have the stock b029 full rom (links available @xda or needrom.com) in the following folder on your sdcard: dload/UPDATE.APP
Make sure this is the extracted file from the zip, not the zip itself
3: power off your phone, press volume down+up+power until you enter eRecovery mode
Happy flashing
In case your phone doesn't recognize the update package, you can download it directly from your phone:
when rebooting, ensure your phone is plugged in via USB to your PC
No luck, bro. Same as before. Phone checks the file, goes from 1 to 4% and then at 5% (when it says "Installing") it says Update Failed. Reboot now.
Tried with eRecovery also (volume+ and USB cable inserted). It connects to WiFi but can't find any package.
I think the only option is to sell the phone and buy a new one with the factory firmware.
Lol, that's not the only option. Download Huawei firmware extractor, extract boot.img, recovery.img, cust.img, cache.img and userdata.img from the B028 firmware (not b029)(you can skip system.img). Use adb and fastboot to flash those files. After you flashed then repeat the firmware flash procedure with firmware b028 in dload folder and vol- vol+ and Power buttons. Did a rollback several times, worked every time for me.

You need your bootloader unlocked. You can use dc-unlocker to do that. It will cost you 3$ or 3€ and 10 minutes of your time:
https://www.dc-unlocker.com/how-to-read-huawei-bootloader-unlock-code
Still more convenient that reselling the phone.
I was hoping that wouldn't be the case. But I guess there is no cure for stupidity, since every time I "upgraded" my phones ever since the Galaxy Note N7000 got Android 4, they always ****ed it up, every single manufacturer. They're not at fault here, I'm the idiot who never learns his lesson.
So yeah, selling my phone it is since if you unlock the bootloader, you lose the warranty and that will make my phone sell for dirt-cheap, since I cannot use it with Android 6.
Thank you all for your help but it looks like this is the only option.
The first chance I get (someone makes a similar-sized device) I will abandon Huawei. Hardware is great but the software is utterly horrid! No-name chinese phones have much better software support than they have.

Unlocking the bootloader doesn't invalidate the warranty, so you're good to go. I for myself love the P8 max, hardware and software. The B029 works extremely good for me after customizing it a bit to fit my needs. There is no reason for me to update to Android 6 since everything works so flawlessly.
If you want to keep the size and don't go any smaller, one of the acceptable alternatives is the Asus Zenfone 3 Ultra, even thou I prefer the design of the P8 max.
Unfortunately, in my retarded country (Romania) I have to call Huawei to get the bootlocker unlock code, which by their terms in this ****ty country, invalidates the warranty. I've been through this nightmare before, with the DAV-701L in which I had to call in UK to get an unlock code, which they even said that I will lose the warranty.
These guys ****ed something up because, here's the kicker : you have to get the unlock code FROM Huawei, which invalidates the warranty. But to invalidate the warranty, you need permission from Huawei. **** logic.
The Zenfone is looking mighty delicious, you know. Thanks for the tip!

I must admit that I'm not overhappy with 6.00.
In exchange of a few new feature I lost root and things aren't so smooth anymore. Gonna roll back as soon as I receive my Xiami Max as a backup phone. Asus Zenfone 3 Ultra will be my next buy, but waiting for a phone so long it's a pain in the ass.. they shouldn't announce models months before they can release them. Like HP Elite X3 (January and just coming to shops) or LeTv X910 (which never saw the light) ?
hi guys,
I apologize for resurrection of this thread but does anyone know the location of the stock b029 full rom file ?
I do remember I was running MM and I want to give my P8 max to my niece but unfortunately it's missing OS.
I could install twrp and I was searching for the file but the links are dead and I think this would be the best place to ask.
Anyway, thanks in advance and sorry for bumping up 2 years old thread.
Peace

bought phone from becetech wont update firmware

im sorry if this is in the wrong section but ,ok so i bought an open box galaxy s6 from becetech online and it would not let me update the firmware past 5.1.1 which made me a bit suss, downloaded root checker app and it came too me rooted. apart from not being able to update the firmware past 5.1.1 as far as im aware the phone has no issues and works perfectly fine. i downloaded the *samsung* phone info app, in general under manufacturer it says Samsung/verizon so im assuming that is part of the reason they rooted the phone as it needed to be unlocked from verizon to be refurbished? so what i want to know is how do i find out exactly what becetech have done to the phone and is there an easy way for me to update the firmware to nougat or at least marshmallow without stuffing the phone, like i said the phones running fine its just really bugging me not being to update. obviously im not able to work it out myself but i can follow instructions so any help from someone would be greatly appreciated so thank you in advance.

Could someone with a bit more knowledge please tell me if the reason I can't update the firmware is because the firmware csc is TGY when I'm in Australia or just because it's rooted or what? I'm getting no answers from the company who I bought it off

Are you trying to update via the phone update feature? If so this won't work as rooting disabled the ability Update using ota
First I tried OTA then downloaded samsung smart switch and gave that a go both no good. What I want to know is, if they had to root the phone to refurbish it will it brick it if I try to update? Won't it reset all the company I bought it off has done to it to refurbish it? Which I'm guessing is quite a process as when I look at the open source licenses there's a long list of files that have been changed. It just sucks that it's locked to a three year old version of the firmware that I'm worried apps will start to stop supporting in the near future? Apart from that I can not fault the phone there's been no problems, maybe I'm asking a bit much for a $400 phone?

From what I can tell you have a g920v variant if the phone Shows Verizon but the sure fire way to know what variant you have is turn the phone off once off hold home-power-volume down, this will take you to download mode but should tell you your variant. You don't need to root a phone to refurbish It, you can flash Stock firmwares via Odin. I really don't know why they would have Rooted It tbh, you'd need to contact them, but I know for sure you can manually download the latest Verizon firmware and the phone should work. Maybe they Rooted it as part of making it network unlocked, o really can't say
Ok I tried that and a bright blue screen came up warning about custom OS then press up volume for download and down volume for reset? I just pressed down as there was no other info on the screen but it does say it's a sm-g920v in the settings as well as the root checker app. Another thing was I did ring samsung support gave them the serial number and IMEI and they said an authorized modification had been done on the phone but could offer no other support as it wasn't an Australian phone. I'll keep trying to get some info out of the company I bought it off and try to sort it out thanks for your help :good:

Help with downgrade?

What i have: a brand new carrier unlocked samsung galaxy s7 sm-g930w8 - came with 7.0
What Id love to do: downgrade to 6.0.1 official touchwiz rom but rooted
What im reading: that the security patch is from february of 2018, which means the bootloader is too new, which means downgrading using odin wont work ( https://www.sammobile.com/forum/threads/36282-Does-Region-Matter )
... so what can i do? i bought this phone with the sole intention of downgrading, as ive seen that it is possible for that phone model (s7) in general
i hate the look of the newer OS. They took the touchwiz out of touchwiz which i loved, although mine is a rare opinion. I want the operation and exact feel of 6.0. the menus are simpler, the notifications area isnt completely stripped of features differing from total stock android. i hate having to pull down twice to see everything. I just really want that older look and feel, but all around, not just a theme.
is there anything i can do to either downgrade or fool the bootloader into letting me carry this out? is this a true limitation, or si that info i found false/old? and if I can downgrade, which build version should I use?
ive been looking here for versions
https://samsung-firmware.org/model/SM-G930W8/ but im not sure which region to go with, or if i can technically use any region
sammobile doesnt list that version anymore at all ( https://www.sammobile.com/firmwares/galaxy-s7/SM-G930W8/ )
https://mobiletech360.co/samsung-galaxy-s7-sm-g930w8-stock-firmware-rom-android-6-0-1-marshmallow/ there are a number of options here but unsure of the different numbers/builds. or if since its carrier unlocked, i could pick any?
I know most will think im silly for wanting to downgrade or caring that much about appearance, but silliness aside... is this even possible??
a while ago, i purchased an s5 mini, and downgraded that with no issues at all.... but its honestly been so long and i cant for the life of me remember the steps i took or if i needed to care about region codes or other numbers. but it did sucessfully work.... it was really built unwell/cheap, but it did work.... its also slower than my captivate glide which is still my current phone, until/if i can get this s7 working the way i desire.
any help and guidance is appreciated. If it is needed, ill be using it with a Koodo mobile sim.
well it is too new if its from DRAG or so onwards (those with U2/S2 in the file name) so no dice, you're stuck with 7.0 unless you want to upgrade to oreo. (and 7.0 firmwares prior to DRAG cant be downgraded to either, not that theres much point doing that)
btw this is the wrong forum to post this in

But this is the forum about s7? I'm wanting to modify an s7?
Which part of the file name are you referring to? Which file?
I would have thought all s7's are made at the same time, and so released with the same overall software, but it all seems so complex now. I've seen s7's running 6.0.1 stock so in my mind it seems they should all be able to...
Not sure what you're referring to with drag either? Does that stand for something?
I'm really hoping this can work somehow, its the last flagship before the edge models which was why I got it, and I love Samsung software up until 7 and 8.
My mom has an s7 as well, not rooted or anything that's too complex for her, but she did the upgrade to 8 and it's still got all the same gross appearance factors that I don't like about version 7. I got excited when her phone wanted to upgrade, maybe they had fixed some of the grossness. But, nope. Wish they had included an option even for stock based or touchwiz based appearance and menus.

go into about phone and tell me the last 6 characters of your build number
(i was referring to the PDA file in a stock firmware zip)
(Also i meant this should be in Q&A section)
Hello,
I can understand you and also understand what you want but Samsung installed a downgrade lock in their bootloader in early 2018,
if you installed this version you can't go back to an older version, I think that was in February.
You can go back from a 6.2018 version to a 4.2018 version for example but not to a 1.2018 version!
If you have a version of for example 12.2017, you can also go back to a version of 2016, so you can also go back to Android 6.01,
if not you only have the last versions of Android 7 or update to Oreo.
I hope I could help.

the last of the build number and the last of the baseband version are the same. But i did take a screenshot of it when i was thinking rooting and changing would be no big thing. figured that would be easier. i purposely havent even hooked it up to wifi yet or anything, said no to anything non essential when i was setting it up... on the chance it was starting up in version 6, and i didnt want it upgrading on its own.
also why would they block downgrading? It seems if anything blocking upgrading would be the way to go, to stop people from updating their devices before official software is ready, not just samsung but any manufacturer. in my head it seems silly to even need to root anymore... someone always figures it out, and cell phone manufacturers must know it. it would be nice if it were included, sort of like developer options, where its hidden, but if you know what to look for its there, and if youre not that advanced youll never find it.
if the bootloader is in fact locked and that is the main prevention, has anyone ever successfully unlocked it before?
ETA: Ive done a bit more looking around and there is alot around about frp and making you sign in to a google account in order to reset.... i have *not* needed and havent signed into a google account on that device at all... does that mean a downgrade is still possible though odin? Or, are these 2 things in fact unrelated...
eta #2: Did a bit more searching around, and it seems to be that in order to root your device, in the process it must unlock the bootloader? If that is still the case, would i be able to then flash the marshmallow stock ROM? Thats what i was looking to do all along, sorry maybe i should have been more clear about my planned method initially. Its a bit more nerve wracking as it seems rooting itself has gotten a little more difficult with that dm verity thing... but I definitely want root no matter which version im running. Ive had root on all my devices and theres no way im going back to a locked down OS (cant remove microsoft stuff for example), i need to be able to declutter beyond what factory allows lol.

TL;DR
your bootloader is currently on version 3, and you cant downgrade to marshmallow
see that "U3BRB2"? that "U3" means your bootloader is on version 3. i assume the marshmallow firmwares use bootloaders pre-version 3 so you cant downgrade to firmwares using bootloaders with version 1 or 2. (this is how it works for F/FD models and im pretty sure samsung made it like that too for the W8 models)
eta 1) unrelated
eta 2) F/FD/W8/S/K/L variants (basically all the exynos models) have unlocked bootloaders. only SD variants have locked bootloaders so it's just your misconception
So, it's literally impossible? Has nobody ever figured out a way to downgrade or mod the bootloader itself? It seems to me the rom makers wouldn't stand for this at all and would figure out a way around it...
I can see an old bootloader can't run new software, but it seems much easier for newer bootloader to run older software, isn't it? You can buy a windows 7 pc and install Windows xp on it much easier than you could buy a windows XP PC and install Windows 7 on it... It's just boggling my mind a little

Off course you can downgrade to Marshmallow. To unlock the bootloader, enable OEM unlocking in devlopper options. After flash TWRP 3.1.0 for Herolte and wipe everything from the recovery. Install any 6.0 roms on XDA for G930F then flash Magisk 17.1 to root and you're done. You can't FRP if OEM unlocking in devlopper is enabled.

You'll trip knox (which breaks features like secure folder, private mode, shealth and Sbrowser private mode) and lose the comfort of OTA updates if you do this tho. Not to mention that you can encounter signal reception problems because your flashed ROM is on marshmallow and your bl/cp is on Oreo or nougat. So I wouldn't advise this method as it may break so many things.

Samsung SM-970U S10e snapdragon downgrade ?

Hi I have a samsung SM-970u ( s10e snapdragon TMO) is there a way to make a downgrade form android 11 to android 10 ?
I...wondered the exact same thing....
but even with an unlocked bootloader it doesn't seem possible if your bootloader version is too high...it was possible when Android 11 first came out but versions may have changed now. I tried flashing with odin myself but I'm getting sw rev check fail... even with an unlocked bootoader.
I'd love to be wrong cause I want stock android 10 but i can't find info otherwise.

What's your current Build/Baseband?
I was wondering if I can downgrade from 12 to 9.
But as I'm reading a lot of posts, I'm guessing it will be next to impossible?

You can never officially downgrade more than one version.
The only possibility would be to unlock the phone's bootloader and flash a custom ROM based on Android 9. But I do not even know if it is theoretically possible to run an Android 9 ROM on an Android 12 bootloader

From what I've learned the phone has a version of the bootloader.
In my case that's version 14 (resp. E because it's hexadecimal)
I found that f.e. Android 11 was released in versions that had different bootloader versions (9, A, B, C, D & E).
So I was only able to install the Android 11 that came with bootloader version E.
And as it stands now, it seems like it's impossible to downgrade the bootloader which in the end makes it a huge pile of s**t on Samsung's or even Google's end.
It's kinda the Apple way of doing things and not letting you do what you wish...

Kind of. Except:
1. Apple doesn't let you downgrade firmware at all
2. Apple doesn't offer unlockable bootloaders and therefore there's no possibility of a custom ROM

From what I've learned the phone has a version of the bootloader.

It's a cruel lesson. Android becomes more Apple than Android with each upgrade.
Literally the first thing I do on a new Samsung is package block OTA updates.
I have two N10+'s, one running on 9, the other 10.
They will stay on that firmware.

Well yes, but the fact that google's core apps are not open source and more and more APIs or libraries are only available on phones that have certain pre-installed google apps takes a big piece of liberty out of android.
My bet also is, it won't get better since google just won't stop generating money in new ways day after day.
But: Android still is a whole lot better than the half-eaten piece of fruit. No doubt.

I hear you.
Was running a S7 with Oreo before I switched to the S10e now and it will stay on Oreo until it dies as a backup phone.
Sadly the seller of the S10e already had updated it to 12, so I'm stuck with at least 11 due to the bootloader.

Android 11 was one reason I bought a new N10+ about 5 months ago versus a N20U. I thought new N10+ be running on 9 but it ended up loaded with 10 due to the manufacturing date. It turned out ok.
I learned the hard way with Samsung and upgrades 6 years ago... and was about as happy as you.
Unfortunately many of the resellers will load whatever is the latest OS version when they test out a phone.
It's more than just a little aggravating. Forget the Google bs hype... I still remember the horror of MS Vista
Hopefully you'll find workarounds to iron out the rough edges or if it really gets on your last nerve return or resell it. Life's too short to live with a phone you hate.

Android 11 is downloading

Android 11 update is downloading and installing as I write this. US model. North American Retail channel.
Just sharing.
My TMO model is also getting notification for the 11 update.... but not taking it. I don't want it to kill Android Auto on my phone.

I'm not sure if it's 11 or 12 (I know 12 does for sure) that breaks AA on phone, but I'm not taking any chances - one of them or both do. This Ace is the only phone I have left with 10.
I'm having a problem with this ota update of my unrooted phone to android 11. It seems stuck at step 3 of 6.
I've seen the update process go as far as 66% of step 3 of 6 several times only for it to restart step 3 again and again. Something does not allow it to complete installing step 3. Internet has been available throughout.
Any suggestions? Is there another way to update?
Researching the web for why the android 11 is not installing on my phone I discovered all the bugs that the moto android 11 update apparently introduces. So I guess I'm lucky the update did not take. I turned off smart updates and will wait to see if and when Moto will get its act together.

It will probably show by now (3 days later). I had the same thing after an unintentional upgrade to 11, but that cleared after only a day when I connected to the Internet again. But apparently the typical wait time is 3 days. (EDIT/ADD) If it still isn't showing, try a reboot.
FYI (all), this phone CAN be downgraded back to Android 10 -- with an UNLOCKED bootloader only. I posted my experience in this Q&A section -- by accident (oops!) so it might get moved at any time to Guides, News and Discussion. Thus I won't post a link here because it might change. If you decide you want to downgrade just look for "Downgrading Motorola One 5G Ace".
I guess I was lucky the ota 'upgrade' to 11 got stuck on step 3.
Android 10 works fine for me except for random reboots. If I find a solution for that all would be well.
