My problem...
I was just given a Yoga Tab 2 from my sister who has given up on trying to fix it.
The tab was on 5.01 and rooted when she got a system update. She ran the update but now the tablet freezes during/after the boot animation.
It will go into fastboot but is not recognized by ADB.
She tried to install the original Lollipop firmware through recovery but ended up getting a system 7 error.
This is exactly what I see when in the bootloader screen
FASTBOOT MODE
PRODUCT_NAME - YT2
VARIANT - YOGA Tab1
HW_VERSION -
BOOTLOADER VERSION - unknown
IFWI VERSION - Blade_21.x64.0005.R00.1504101447 FFD8_X64_R_
SERIAL NUMBER - BaytrailD454B***
SIGNING - ?
SECURE_BOOT - ?
E: No valid installer medium found
I know nothing about Lenovo and how they do things but I know that with HTC you have to go back to 100% locked and stock before you can install an OTA. If you do try the OTA usually just won't install but unfortunately this thing seems to be at least soft bricked.
Is there a way for me to maybe roll back? I've read about people going back to KK in order to get the LP OTA but all links to the KK firmware are gone.
Thanks a lot, I appreciate any help I can get...
BTW, She is under warranty but of course she was rooted and is worried that repair will cost her almost as much as she paid for the Tab when they realize and void her warranty.
If its the same as the 1050f try these files.

Thank you. I used the Restore KitKat Bios you posted along with an 830F specific KitKat firmware from the Russian Lenove site. Worked fine after editing the flash.xml file to allow for a larger system.img file.
The tablet is now back from the dead. Unfortunately it gets the 5.0 update but fails in the Lenovo Recovery when trying to flash the OTA. It gets to 100%, stays like that for a bit and then a blue X saying flash failed. After that I'm back to a black screen and have to reflash the kitkat firmware to get up and running again.
I have no idea why the OTA flash constantly fails but I guess I have to do a bit more research and hope I can get her up to date.
Did you set the country code , without setting it updates fail.
Look at this advice from ionioni to me about setting the code

Outstanding!!! I entered the code in contacts and it gave me a menu of different countries to choose from. I Chose US and she rebooted, went into recovery, ran a bit and rebooted into another fresh install which looked completely different. We're talking different wallpaper, and different apps. After that it successfully installed 4 or 5 OTAs and as far as I can tell it is now completely up to date!
Android Version is 5.01
Build is S100250-160119
Kernel Version is 3.10.20-x86_64byt-g9f7fad7
Security patch is dated 2016-02-01
I'll wait a few days before I root and install Xposed just to be 100% certain it's up to date.
Of course my sister will probably ask for it back now.
Either way, THANK YOU VERY MUCH corasman!!! Your help has been invaluable!
I am so pleased it worked for you, ionioni helped me so much and now I am trying to do the same for others.
First excuse me for opening an other thread like this, i think i have read all other threats regarding my problem, but none have the same situation
My Huawei M3 Wifi (BTV-W09) seems semi bricked after installation of Nougat Update.
The Installation (Force Install with dload) gave me an error and also while boot i got the error message: "Your device has failed verification and may not work properly."
I have the option to press "Powerbutton" and the device will boot up. I checked the Version and it showed android 7 + EMUI 5. The only problem was that almost every system app was missing, like keyboard, calendar etc. (playstore was there)
So i tried to do the rollback with:
HUAWEI MediaPad M3 8 Rollback Package%28BTV-W09 %2CC900B300%2C EMUI5.0%2BAndroid7.0 rollback to EMUI4.1%2BAndroid 6.0%29
The Installtion (force update) gets stuck at 5% and after like 3-5 minutes the tablet will boot up showing the same boot error that can be skipped with pressing powerbutton. I checked sytem and it still showed "android 7 + EMUI 5" but built : BTV-W09C900B300
I think this is the one i "need" to be able to install the "HUAWEI MediaPad M3 8 Firmware %28BTV-W09 %2CC100B006%2C EMUI4.1%2BAndroid 6.0%29"
Problem is regardless which "update.app" i try to force install will get stuck at 5% and give me same error. I have ADB/Fastboot installed and tried some different things like flashing/unbricking it with "Huawei Multitool" where you can extract like boot.img or recovery.img and try to flash it.
Also getting an error. I can access eRecovery witout problems, the option to fix it by itself by wifi doesn`t work. I can´t access "normal" recovery and i think there is the problem (may got bricked while flashing Nougat?) I think its recovery problem, cause when i boot it up to the "half-installed" Android and go into setting "hard-reset" option i know it would boot up intoi recovery and would erease everything, while bootup it shows error "reset failed".
In fastbootmode i see bootloader: unlocked FRM: unlocked
I tried to install TWRP recovery with adb but get error: adb remote command not allowed
I downloaded like 15 different Android Versions 6+7 Emui 4.1+5 to try with force update but none worked, may i have to flash special version of recovery first?
I just want a normal version of android 6 or 7 i dont mind but at the moment with half working 7 "without" systemapps its a hardtime.
I hope someone can help me.
This isnt my first android device and im not a total noob i unlocked bootloader and flashed kernels on many other phones but with the W-09 where i did nothing special i dont get why "recovery got broken"
Thanks in advance
You haven't read other threads too well: more times people reported that the bootloader got locked after an update still declaring itself unlocked!
Second thing you have not found: the Nougat update consist of 2 packages and the second must be installed from TWRP.

thanks for your anwser, i read that so i also tried unlocking it "again" and it quotet it is also unlocked in adb. I also know that there are 2 packages. That you need TWRP i didnt know thanks so i am a bit smater now. I think i ll try "relock" and unlock it again might be the right way, thanks for the tip.

This is nonsense. Unlock, install the right TWRP then install the second zip package.

i cant unlock cause i dont have the code, on the huawei page i try do make an account and get the code by providing the necessary information.
I just uploaded a picture, i choose "before EMUI5" cause this is the only option i can choose "tablets". --> i choose "tablet wifi" , enter product model "BTV-W09" then the serialnumber i can see in setting: 28D6R17316XXXXXX but then i have the problem to input product id, it say i can get it through "Dialer" app (which i dont have in wifi model ) or the calculator. Problem is in my damaged installation there is no huawei calc, other calcs from store dont work (read that problem in other threats) I tried many apps from appstore to get a product ID but huawei site keeps saying wrong product ID =/
With the program DC Unlocker i am able to see a MEID i dont know if its the right one, i tried my luck with the Product ID Generator from Huawei but it doenst work. (device not supported)
It's very strange that it says bootloader unlocked if you have never unlocked...
And was very stupid to try to installl a beta release without before unlocking and taking a backup.
Exhange your device for a Nokia 3110!

yeah at this device i never touched bootloader, i didnt think it would become such a big deal , i didnt want unlocked bootloader or other recovery just newest android. Never had any problems with the "force update function" to come back to stock. I tried DC Unlocker but cant get further cause device need to get into manufature mode (thorugh dialer or calculator which i both dont have) i hope maybe i find one more way.
Did you ever find a fix
Did you ever find a way to fix this. I'm in the same situation. I even did a VPN on my router to give me a Hong Kong address for erecovery and that still didn't work. I have the exact same product. Like you I tried to various attempts to download a new recovery, but nothing works. Nice hardware, but some of the worst software/firmware I have ever dealt with since starting with the first release of Android on the HTC Hero.

I had mostly the same problem. I rolled back to 4.1 using the rollback and the actual 4.1 update.app. I think that puts you on C100 if I remember right. Tablet I have is C128 (USA) but no problem for this step. Get the Product ID from the calculator. Allow OEM unlock in the settings, then unlock it using the unlock code. Email yourself the unlock code because who knows if their website will even be functional next time. Alternatively you can extract the stock calculator from the update_data_usa.zip or whatever and try to use DC with 5.0. That second update zip does not install properly via the dload method, so a bunch of stock apps don't get installed. You can kind of hack it and flash it via TWRP but I didn't do it that way.
Or...you can use firmware finder to force an OTA from 4.1 right up to 5.0 (350), then take that last partial OTA to 351 after as well. The way to do that is via DNS in firmware finder. Find the Full OTA in firmware finder you want, send it to the updater by changing your DNS the way it tells you to, and when it does the OTA, everything will be properly installed basically the official way. Good as new. Flash TWRP to recovery2 and replace the erecovery. Keep the stock recovery as is. Install magisk. Golden.

Also, as far as the rollback, you need to do the first one (the C900 which is just a compatibility fix to allow rollback, previously used by beta testers I believe). Then you need to do the second one, the C100. If it is getting stuck, try downloading it again and be sure you don't have anything else in the /dload directory on either internal or the sd card. I had one on both at one point so maybe that happened to you. The C900 should be very quick but the C100 will slowly progress after 5% all the way around in several minutes.
When you get to updating back to 5.0, you can choose whichever region you want as long as it is a full OTA. C128 is USA and that's what I bought so that's what I picked. That gets you back in the right OTA update channel after that.
Hi guys,
I started as a novice and have learnt the hard way.
Has anyone tried rollback to EMUI 4.1 EU version on a US device (W09) and are there any problems I should be aware of?
I have had the exact same problem shared in this thread and have gone through the pain of finding a solution. My last resort is to rollback to 4.1 and restart the whole process.
@deV14nt: you suggested that when updating back to EMUI 5.0, I can choose the region even if my EMUI4.1 is EU version. How does this work?
Thanks in advance for your help.
Hi All,
I'm trying to update the p9 lite VNS-L31C432B414 dual sim to the latest version B416.
The phone is always officially updated, but i tryed all 3 versions from firmware finder, with the *#*# 2846579#*# *
Select Project Menu > Software upgrade > SDcard upgrade method.
But when the phone restarts it begin to update and after a little progress it failed.
The same thing happens when i try it with the firmware finder app from playstore with erecovery, or dns method.
Any help would be appreciated, thanks!

Firmware Finder
DNS/VPN method should be the best way to try this update.
The other only method that i know is to use Huawei Recovery Updater
but you should unlock the bootloader and flash a custom recovery first.
In the end it will be a bit difficult to re-lock the bootloader, never tried to do such a thing,
but you can keep it unlocked...
Good luck dude.
Cheers
Hi Dadditz,
Thank's for your response.
Last night i have tryed with a extra wifi router to change the dns number but even when the Firmware Finder app giving me the message that the B416 is registered for my phone, when booting in erecovery it installs the B414 FULL package again.
And with in the app proxy and dns method with firmware finder, the system update app from huawei gives me the sign that a update is ready to B416 with the release notes and all but when it starts it shows a checksum error or download fail.
I have registered the IMEI but do you know if it's maybe the problem with that its a dual sim so there a 2 IMEI numbers? or is the first one enough to register?
The tip for unlocking the bootloader i have searched on, but huawei has taking the unlock service down i understand, so the dc-unlocker2client program for 4 euro is the only option i think?
The main reason that i want to try the latest firmware is that people can't hear me good with this phone, i send the phone 2 times for repair and contacted the provider but the signal looks good.
Now i have factory reset the phone for the tenth time, i was thinking maybe the eset virusscanner interferes with the build in huawei/avast scanner but im not sure if that could cause it.
Thanks and have a nice day.
Hi all
I just unroot and unlock BL my phone yesterday. First i make downgrade (rollback 6.0) via dload method. Everything going very smooth and when my phone was version VNS-L31C432B160, then i'll get all newer updates via OTA (Finland), now my phone is B416

Hey dude it's like you somehow downloaded B414 firmware and putted into
the internal memory or the SD card.
Check if you have that files and delete them, then try again with the update.
Don't know about your two IMEI, you have to check by yourself wich one would work...
About unlocking the bootloader, yes it is possible with the tip you wrote (dc-unlocker).
Before attempting to do anything try first with another sim and see if is the same as now
because if nothing changes maybe it's a hardware issue...
As suggested by @oltsuboy it's possible to downgrade to MM and re-upgrade
to N android version, you only need the correct packages..
I'm here to help you...
Have a good day..

Hi guys,
I have tryed to downgrade to android 6, and that works, and then i get OTA to B370 and then B380 so i am android 7.0 again.
But now the OTA update find nothing, it stays on B380.
Before when i checked system update with HiSuite it says B414 is the latest official firmware, but now it says B380 is??
As far as i know i used only official updates with this phone, and i have wiped partion and system a lot of times.
And mostly there where 2 sim cards in it, i only put in SD card formatted first for the update.app
So i don't think B414 is floating somewhere, but i don't understand where it went wrong.
It's a non provider linked phone with a sim only abbo from the netherlands, i already asked a new sim card from the provider to test if the voice quality improves but it makes no difference.
I'm gonna wait a little maybe a update comes, when i put the B416 update on the sd card now and do force update VL+ VL- PW. the update fails after ten procent.
Maybe tommorow im gonna look to unlock the phone for 4 euro.
Thanks for the help!
Update: I have tried the DC Unlocker program.
And obtained the bootloader code, but what do do with it now?
Something says i did something wrong, because the options where:
Read unlock codes
Read bootloader code
Lock Bootloader
Erase Huawei ID
But no unlock bootloader, so i did read bootloader and copied the code.

Hi dude,
DLOAD aka three button method won't anyway work on android 7 versions...
Sorry did you tried with your brother/sister/friend sim and seen if it's the same behaviour ? ( about the weird quality voice ).
Keep your unlocking code safe and before attempting any unlock re-try to update via Firmware Finder, checking this way...
Obviously turn on and connect with the WIFI...
After installing the app open it and add your variant (VNS-L31C432).
Find the firmware you're looking for (VNS-L31C432B416 FULLOTA-MF 2,2GB) and tap on it.
Now check the availability, register it with IMEI for the update and use the dns change / vpn method.
Once the vpn started, check repeatedly into the stock inbuild updater for a update and the B416 version should come. If will be disponible tap and download your update (should be approssimatively 2,2GB).
When it'll be at 5% pause it for a while and stop the vpn service.
Go back and re-active the download of the B416.
If all will go well you'll have the latest firmware.... :laugh:
Let me know how it went.
Cheers
Hi Dadditz,
No i don't have tryed another sim yet, the provider has said that if i give to more telephone numbers from the same provider they can do a scan for the quality.
So maybe that's something to try.
Later at night there came 3 more updates and the latest is now B414, so i am back on the same build
Yesterday i have unlocked the bootloader, with this guide: https://forum.xda-developers.com/huawei-p9lite/how-to/guide-unlock-bootloader-twrp-root-t3405701
Yes sorry i couldn't wait so i think let's try
When i was at the TWRP part, when i must reboot to recovery mode it stays on the screen that the phone was not safe.
So that part i still want to proceed.
So i rebooted and go to sleep.
I just have tryed your tips, but i see the same behaviour, the download fails, the extra wifi router which i changed the dns to was not more in my network, so i tryed without it.
With my own wifi router at home, they don't allow the change of the DNS, can that be the problem? or if you put a extra wifi router to it it's no problem?
I attached some screenshots, do you see that the buildnumber is displayed 2 times after a row?
I maybe think that's because i tryed to register both the IMEI? so maybe that's a problem?
Sorry i don't know how to attach the screenshot's below.
So i put them in a album called B414 with my profile, i hope you can see them, sorry this is the first forum i post on.
Thanks a have a nice day :good:

Hey mate,
you're such as educated guy and i really apprecciate that !
Well... i saw inside your profile the B414 album and maybe i found the mistake...
damn ... seems you didn't read carefully what i wrote !!!
Look in previous post, you need the FULLOTA-MF package 2,2gb !!!
not the OTA-MF (incremental) one !!
Repeat again the procedure, register one only IMEI, hope this time
you'll be able to update correctly
Let me/other members know.. :fingers-crossed:
note: if the update will end correctly, it will re-lock the bootloader too.
Cheers
Hi Dadditz,
Thanks i didn't even finished my school so my english is not good, but i hope u understand.
I always tryed to install the full package mf B416 2.2gb but when i was testing it with the extra router it always shows a checksum error or download fail, tonight im gonna try that again, and let you know how it went and describe the steps that i tryed so maybe you can see where it goes wrong.
I also tryed the firmware finder windows version to register the IMEI, so maybe i make a mistake there.
This afternoon i was trying to attempt to proceed with the TWRP installation, but when i was booting with VL+ and power it won't go to recovery mode, on the xda forum i was reading more people with the same problem, the phone stays on booting
But the phone is working now so im glad i can whatsapp and watch netflix, so i will not try to go further with that, and focus on the B416 full update.
Thanks:good:

Can you describe maybe how i can insert screenshots in a post?
When i try to insert a image in a post it is asking for a link, can i upload pictures at XDA or do i must use another image upload server?

Dude,
sorry if i wrote something that someway hurted you,
english isn't my main language too...
Attachments aren't allowed to junior member, you need to post many times
in order to be authorized.
Let's go to the main problem...
If you want to try to flash the B416 version with the TWRP
you first need the correct TWRP version...
If you followed the link you posted above,
you tried to install the marshmallow version,
that's because it won't boot.
Your device are running android 7 ( nougat ) and you need a working recovery
in order to use Huawei Recovery Updater ( HuRu ) and flash that B416 firmware.
All files ( firmware apart ) you need are present on XDA, so just download and install
what i wrote you here.
Be sure you have installed Hisuite on your PC and it works.
Be sure you have enabled developer options then open it and
disable screen lock, enable oem-unlock and usb-debugging.
HERE to download and install Minimal ADB & Fastboot on your PC.
Connect the device to the PC, make sure PC recognize it allowing permissions if needed.
Then on the PC open a prompt (CMD) with admin rights and type "adb devices".
Below you should see your device as a serial of numbers and characters like
THIS screenshot. If that worked go next step.
Type "adb reboot bootloader" and it will reboot into fastboot/bootloader mode.
Now type "fastboot devices" and you should see your device as a serial of numbers and characters like
the screenshot i posted above except you'll see authorized/unauthorized section.
If your device are now authorized you're ready to go.
Type "fastboot reboot" and it will reboot into system.

Dude,
sorry if i wrote something that someway hurted you,
english isn't my main language too...
Attachments aren't allowed to junior member, you need to post many times
in order to be authorized.
Let's go to the main problem...
If you want to try to flash the B416 version with the TWRP
you first need the correct TWRP version...
If you followed the link you posted above,
you tried to install the marshmallow version,
that's because it won't boot.
Your device are running android 7 ( nougat ) and you need a working recovery
in order to use Huawei Recovery Updater ( HuRu ) and flash that B416 firmware.
All files ( firmware apart ) you need are present on XDA, so just download and install
what i wrote you here.
Be sure you have installed Hisuite on your PC and it works.
Be sure you have enabled developer options then open it and
disable screen lock, enable oem-unlock and usb-debugging.
HERE to download and install Minimal ADB & Fastboot on your PC.
Connect the device to the PC, make sure PC recognize it allowing permissions if needed.
Then on the PC open a prompt (CMD) with admin rights and type "adb devices".
Below you should see your device as a serial of numbers and characters like
THIS screenshot. If that worked go next step.
Type "adb reboot bootloader" and it will reboot into fastboot/bootloader mode.
Now type "fastboot devices" and you should see your device as a serial of numbers and characters like
the screenshot i posted above except you'll see authorized/unauthorized section.
If your device are now authorized you're ready to go.
Type "fastboot reboot" and it will reboot into system.

Hi Dadditz,
No problem mate , i'm new to this phone flashing and was insecure if my english was good enough to communicate on the xda forum.:good:
I was just to let you know that my second try with the second router is maybe succesful for the B416 FULL update part.
I now connected my pc to it and when i changed the DNS i changed the second DNS to 1.2.3.4 and when the firmware app says registered to this ip:......, i took that ip in the second router.
And then boot in to huawei Erecovery and now the B416 2gb is downloading, why the DNS and PROXY in the app only provide the 700mb update all the time even if i registred the 2gb version i don't know.
Maybe the DNS or ip setting had something to do with it, my understanding of network settings is limited.
The download is 42 procent after a hour but it's a old wifirouter.
So i was now about to ask if it's succeed i could undo the TWRP and lock the bootloader and just read your message, so i don't know if it hurt's anything if i let the update install
I wait and see :good:
edit: i did see you message that the update will relock the bootloader but i was asking because i was not sure because i messed up the TWRP part. edit
The update to B416 was succesfull! :good:
I haven't see the warning that the device isn't save when booting and Netflix appears in Google Play store again, so i guess i don't have do anything more to disable TWRP and locking the bootloader
Thanks for the help Dadditz and sorry that i was impatient to wait on your message, in the future i ask and wait patiently, but hey i didn't bricked the phone
If the voice quality improves i now must test, and the next step is to ask a network scan from the provider on 2 more telephone number in my town.
Thanks :good:

I suggested, you did. :good:
All is well that ends well.
If you had TWRP recovery installed,
you wouldn't be able to update with Firmware Finder,
as you would have needed stock recovery ...
And yes now the device is 100% stock.
Thanks for your feedback dude.
All the best
Hello everyone,
I explain you my problem:
I tried this morning to update my samsung galaxy A41 SM-A415F rooted with Magisk (firmware patched via magisk) to the latest version (A415FXXU1CUH2) that can be seen on sammobile :
Download Samsung Galaxy A41 SM-A415F XEF France A415FXXU1CUH2 firmware
So I tried to update the phone by setting the HOME_CSC to odin but what was the surprise when the phone rebooted? Some partitions were corrupted and I had no choice but to reset the phone.
I wanted to reset the phone with the last ROM and so I started the installation on odin BUT I checked the option "Nand Erase" and "Re-partition" and since then the IMEI number has been deleted and I can't put it back nor send messages / calls etc.
I have searched everywhere on the internet and even trying to put back the last ROM doesn't work and when I want to do *#06# the message: sm-a415f is not supported on showIMEI is displayed
After a while I found a tutorial on the internet that said I had to put the .pit file of my rom in the "PIT" tab on Odin in addition to my ROM because I had deleted all the partitions of the phone... I checked the Re-Partition option in addition to F. Reset Time & Auto Reboot to register the .pit but it didn't work, I always get 2 errors: One when I reset the phone before the menu with all the apps is displayed telling me: "IMEI or MEID is empty" and another one when I try to see the IMEI number when I press *#06# in the phone app telling me: sm-a415f is not supported on showIMEI
I thank you in advance for your help,
Sincerely.
Edit:
Oh yeah, and the phone doesn't detect the sim card even when I take it out and put it back in...
Hello,
i also have a similar problem.
I rooted the samsung A41 smartphone with magisk. After a while, I wanted to go back and put the original firmware back. Everything worked until I installed update A415FXXU1CUH2. Now the IMEI is empty and the sim card cannot be used. I went back to the A415FXXU1CUD4 version and now everything works fine. I initially blamed all these problems whit the root, but looking around on web I saw that the IMEI problem happens.
Can't read SIM cards after the latest update
Hello, I received and installed a firmware update two days ago. I noticed cell signal icon was replaced by a crossed circle; . Also, the options for 4G and 5G are nonresponsive, the menu options are not greyed out but they are unresponsive when pressed. So I can't connect to my cell service...

Samsung A21s software update problem
After the last update.. I have lost my connection to 3g/4g ... my phone only connects to my home wifi... but doesn't connect anywhere else. Any advice?
eu.community.samsung.com
Problem: IMEI is null after updating to A415FXXU1CUH2. Cant call, message or use data.
Solution: Flash earlier firmware or restore from your full backup.
I confirm this IMEI problem and that the @Arazon´s solution works.
I tried to update the phone to the latest stock firmware Android 11 (A415FXXU1CUH2) from an earlier version. I got everything to work except the IMEI showed null. I tried flashing with both root and non-root. I tough I had broken the EFS-partition but luckily that was not the case. Somehow the IMEI could not be red with the newest firmware. I guess Samsung needs to fix it and we have to wait for a few months? Anyways I will try updating the A41 "the normal way" and then flashing my root after that. Maybe it will work.
I wonder when we get the unofficial LineageOS for the A41 SM-A415F. Hit me up if you are up to it, I might be able to help.

I tried updating the A41 with bootloader locked but the results were the same. It seems that if you have tripped the Knox (voided warranty) the recent update A415FXXU1CUH2 will somehow break your imei and it will show up as null.
These firmware versions (root or non-root) do work and the imei problem does not exist even with tripped knox and unlocked bootloader:
A415FXXS1CUG1
A415FXXU1CUD4
A415FXXU1BUC3 and older
Edit 3: TL;DR: This is appears to be an S8 exclusive error, it's shown in the recovery:
"Product device tree not found, couldn't verify firmware" or something like that. For solutions, please look that up.
So, I bought a bootlooping S8 in the hopes of fixing it.
Since OEM and FRP lock are on, I went with installing Samsung firmware on it, as installing a custom recovery at this point is not possible.
The default recovery wouldn't work, so I wasn't able to know which firmware exactly to flash, because I couldn't find out which model exactly I have bought.
I do not know the carrier of the device either, but it should be from some german provider.
All of the firmwares I tried just bootlooped, but the recovery works again, except for ADB, which is quite unfortunate, and I have no idea why it fails, the device shows up when I'm in the recovery menu, but as soon as I activate ADB, it's gone from the list of connected devices.
Combination firmwares sometimes show some turning gears animations, but then crash with some, thought often memory related, pretty random crash issue.
Another problem I am now facing is that in the process of trying to find a working firmware I now upgraded the devices "binary level"? (forgot what exactly it was called) to 6, so I can't flash any older firmware or combination firmware than 6, since downgrading isn't allowed.
I received the device with either binary level 1 oder 2.
My theory is that I don't have the right firmware, since I keep seeing dm-verity and license errors...
I am happy to provide logs if necessary.
The goal is to have an unlocked bootloader/ custom recovery.
I literally am going INSANE over this FRP blocking me from flashing TWRP and being done with this in under 10 minutes, please help :c
PS: Some random info attached
Edit 1: With the IMEI code i found while opening the phone I now know my model number: SM-G950FZKADBT.
Any tips for finding the PDA code of the originally installed system? Or finding a matching firmware?
Is this even neccesary? Why do official firmwares not work for me? :c
Edit 2: Somewhat solution: I think the only way to recover this device would be to find it's firmware, which is just NOT to be found...
So, until a miracle happens I'm gonna keep reading "Firmware is not valid" errors in the log
Did you look in samfrew.com ? ? ? I just grabbed a fw from there.
The dnld was loooong so I purchased a privilege for faster speed . . .
