Okay guys I'm tired. I don't understand why it won't works : I have a brand new Huawei P9, it's a Dual Sim (L19-C185). It's not branded. My current firmware version is EVA-L19-C185B170. I don't want to root or unlock if possible, I just want EMUI 5.0. I've tried to install it (mostly firmware B385, no particular reason) by using the firmware finder, by using HiSuite and by using the "dload" method. None of it worked, it always fail when it "verifies package", or when I use the "dload" method, just after (it tells that the package I've downloaded is not compatible with the version currently installed).
I don't know what to do anymore. Why do I even don't have the OTA ? Is it still deploying ? Do you see what I'm doing wrong ?
For information I've more or less followed this tutorial : http://ministryofsolutions.com/2017...gat-b385-update-emui5-middle-east-africa.html
Note : I didn't use the absolute last version of HiSuite, but almost. Can it come from there ? When I install using Hisuite and Huawei Adapter, Huawei Adaptater warn me that it coudl brick my device since I checked "custom rom" (which make me thinks that it should force the flash), HiSuite tells me that it installed successfully, but my phone just says that the package is incorrect. But it IS the correct package. I did all of this for numerous other brands, but now I don't know what to do anymore.
So, I sent the phone back.
I realized that, even if the firmware was EVA-L19-C185B170, it was actualy a TL00. I think that TL00 is specific to China Mobile (or perhaps other Chinese providers) and that they haven't develloped an official rom for this phone. On my phone, EVA-L19 was somehow flashed, and the bootloader was locked, which means that the vendor successfuly crossflashed a rom that was not intented for this model, without unlocking the phone, or by unlocking and then relocking the phone. If I believe this forum, both methods are currently unknown. However the fact that I had this phone prove that at least one of those two methods is possible. Perhaps more information can be found on the Chinese web. Knowing none of these method, and being unable to update (the low-level software somehow know that my phone is an LT00, and won't update to a firmware which isn't. No LT00 Nougat seems to exists. So I was ****ed) and not willing to unlock the bootloader to try flash without any garantee (I think that hardware are the same, so flashing a L19 Nougat should be fine however), I send back the phone, and bought another, which seller garanteed me it was a L19.
If you run into the same issues, Good luck.
Same Issue with Me
I have been trying to find an upgrade. And my phone is on same firmware as you mentioned. Even I have bought it online from China, and i suppose I am facing the same problem, about it being an original TL00, but tweaked to L19.
I cant send the phone back as i reside in another country!!
Any possible solutions you may suggest?
Can anyone please help with the same..!!
I have a tab s2 sm-t710 on nougat T710XXU2DQCL that was installed OTA and would like to know if i am able to downgrade to 6.0.1. The device is 100% stock and was wondering if ODIN would give me any grief about downgrading. The PDA number of the 6.0.1 file is T710XXU2CPK1 (Cellular South).
Thanks
On paper, I think you should be fine. :angel:
I'd also like to know this as battery life seemed much better on 6.0.1 for me.
i did downgrade my T 815 from 7.0m to 6.01 using odin. didnt face any difficulties. i did a complete wipe/format after i downgraded .
Can you not downgrade with TWRP as well?

I used Odin and firmware downloaded from sammobile and it worked flawlessly. I've performed downgrades on over 100 tablets so far and they have all worked good.
Downgrded my t713 long time ago and didn't have a single problem, you just need to download a compaitable firmware from sammobile!

You're safe to downgrade as long as it's allowed. Older builds will fail immediately so there is no harm to downgrade.
I've seen a few people asking about downgrading. Whats the reason behind this? Is N glitchy?

N does not work at all well with DJI drone remote controllers. I foolishly updated my brand new SM-T719Y 8" and Now I cannot connect to my drone at all. I have an pre 2016 Tab S2 on Android 6.01 and bingo works.
This size pad is the preferred size for drones and has enough grunt to provide stutter free vision. Cannot comment on anything else about N as this pad will only be used for my drone...

Hi Beut,
I have been trying yo downgrade my Tab S2 SM-T719Y LTE from Nougat to 6.01 and have correct downgrade and Odin. Every time I try to downgrade it fails straight away, so I was wondering what you ment by "as long as it is allowed" & "older builds" will fail immediately.
I need to get this happening as I cant fly my drone.
Cheers Yts...
I don't have your model so it cannot verify. However, other models I can downgrade to older builds close to the Nougat.
Like SM-T580 or SM-P580, both are Android 7, QF1 and QE4 respectively. I can downgrade them to PL4 or PL2, Android 6 but not the PG1.
Q: 17 or 2017
P: 16 or 2016.
The second letter is the month it's released.
You also need the right bootloader, different OS has different bootloader. Many just flash the AP file only without bootloader, it'll failed when downgrade.
Is it possible that you cannot downgrade Nougat to 6.01 as every time I try on my SM-T719Y Tab S2 LTE, it fails straight away. I have tried 3 different downloads and all failed, but Odin will let me overwrite my Nougat with a downloaded version of Nougat from the same web location as I got one of the 6.01 firmwares from.
Here are my fail messages.

Is it me or is it this model of the Tab S2 SM-T719Y????
When downgrade to MM you need the BL ( Bootloader ) goes with the AP . Boot loader of Nougat is not the same as MM , however bootloader of LTE version is locked
Sammy doesn't want you to downgrade.. nougat is planned obsolescence, I'd say.

Hey I've been trying to downgrade my T719Y for days now. Constantly failing and googling everything I can to find where I'm going wrong.
How would I know if I have the LTE version? And if I do and the bootloader is locked, does that mean I can't downgrade?
If I don't have the LTE version, you're saying I need the bootloader and AP to downgrade? Where can I find the bootloader?
I'll keep searching and trying but this is wearing me down. Any assistance would be greatly appreciated. My surveyors can't do a damn thing with our giant UAV until I fix this
LTE version is the one that has SIM, usually it's next to SD slot. Most LTE versions have locked bootloader, that's why you cannot downgrade firmware.
I just kept an older phone for apps available only for 6.0. Like scr recorder. Otherwise there are no reasons to downgrade
Hi,
I've wanted to try a One UI Pie rom, which I did, I like the new user interface, hate the new camera. I put my feedback on One UI as a PS at the end.
I believe one of the ROMs i tried required me to update bootloader to Pie. Is there a way to downgrade to Oreo, so i can install Oreo ROMS? I tried 2 ROMs and i get a boot loop on both.
Thanks,
Daniel
PS: One UI feedback: Used to be able to take either video or picture one click away, now it's 2. You used to be able to bind the Bixby button to Camera+Take picture with BxButtons, and volume keys to video. No longer possible with Pie. You don't know how important that is untill you went to the mountains, and you need some phisical buttons to use with your gloves. And most important, adding the Dual Shot mod is no longer possible, which was taking the same picture or video with both front and back cameras, which is again verry important for me.

We need to know what your current "Build Number" is on the phone. You also can't downgrade to other bootloaders that are lower then your current one, so if you're on bootloader 5 you need to use the Oreo bootloader 5 version firmware or it will not work.

That's not a normal Samsung firmware.. Where are you from? Was that phone rooted or something? Considering that you have a different rom on the phone it looks like it's bootloader unlocked.. I'm assuming you're not from the USA and that your phone is a N950F correct?

He is asking for the "N950FXXS5CSA2" firmware to see what bootloader you are on. (Bootloader # is the 5th spot from the right. This case the "5" from "5CSA2" IS THE BL. Version)
Usually it's in about phone/software/ baseband if not there it should say in download mode (look for B: # (# could be 1 to 5)) few lines down I think.
If your on bl. Version 5 you can be able to flash any N950FXXS5..... firmware but not lower like N950FXXU4......

Hi, yes the bootloader is unlocked, I have a custom ROM, and my device is Rooted.
Baseband version N950FXXU5DSB1. So N950F, bootloader 5 I guess from what @BluePhnx said. Is there a direct connection between Bootloader 5 and android PIE? Or can Oreo ROMs be compatible with this bootloader?
Thank you for helping me clarify!

The only connection the bootloader plays is when you go from pie to oreo.
For eg. Oreo is N950FXXS5CSA2
Pie is N950FXXS5DSB2
As long as the bootloader is the same "5" you can go back and forth between pie and oreo.
BUT once you go to a, for eg. let say August security patch for pie, firmware with N950FXXU"6"DSB4 (this has bootloader version 6) then you can NOT go back to oreo. Because the bootloader won't downgrade itself, it will only stay at version 6 or go higher to version 7 and so on.
So if you want to go back make sure the bootloader stays at version 5....

See what @BluePhnx said? That's what I was trying to explain but he explained it better.. If you want to know what bootloader version you're on you do this see N950FXXU5DSB1 what you do is start at the very END and count backwards 5 letters/numbers and you end up on the number 5 like N950FXXU((5))DSB1 that equals bootloader version 5 but if you see something like this N950FXXU((6))DSB1 then it's bootloader 6 and if you were to flash that one you can never go back to bootloader 5 again it only goes forward but @BluePhnx explained it much better!

What is your CSC?
Warning I haven't done this yet since I'm staying on pie. So do it on your own risk! I'm just saying what other people done.. Also I would've done it myself too.
Download the last oreo firmware for your CSC. (The one before Pie.)
Download Odin 3.13.1 or the latest version on computer.
Flash Oreo and home-CSC
But if it doesn't work or you get lots of force closures messages then do this steps.
WARNING!!!! this will erase all data off phone so backup FIRST!
Factory reset phone
Flash OREO with CSC file (NOT the home-CSC)
(What I've read people are saying to do the factory reset option for it to work. I haven't tried it myself since I'm staying in pie. That's why I included the first option.)

The problem is most custom ROMs don't actually tell you the firmware code or bootloader version. And I only saw 1 ROM that actually told me that it will update the bootloader to PIE (without specifying the actual version). Do you have any pointers on what should I look for when installing a custom ROM to prevent upgrading bootloader (besides when the ROM actually specifies the Bootloader version of firmware code?

The rom should say what firmware it is based on. Like N950FXXU5DBS2. If not you can ask.
Eg. N950FXXU5DBSA2 - the "5" in ....5DBSA2 is the bootloader version.
You'll can check for your bootloader version in download mode.
Here is a screenshot: (not mine just an eg.)
But you should be able to flash back to an oreo bootloader as long as the bootloader version is the same.
Cannot open PIE after OTA upgrade last Friday.
After upgrade with previous release and security patch of 1st of January I checked somewhere last week and there was n upgrade then.
Last Friday I did see a new OTA update from Samsung and installed it, upgrading to PIE.
After restart I get an error with the SIM card slot. I have a dual SIM version in Spain PHE.
I am unable to use phone now.
Everything original. Only did the dual SIM + memory card. Which has been working perfect for me with OREO.
Which version would I need?
Did the official PIE update change the bootloader version as well?
I just need the double SIM and the memory.
Any help would be greatly appreciated.

No there isn't. That I know of.
Pie needs the pie bootloader.
I think the only way is to root your phone and have a dev port the pie firmware to work with the oreo bootloader. If possible!
But you "should" be able to flash the 1rst pie release firmware and then go back to the last oreo firmware with a factory reset. (Not certain though so. )

1rst pie bootloader?
What about this one: N950U1UEU5DSC1
Hi.
I just received the Pie update to my Not8 256GB.
First I would like to check the actual version of my phone. I assume it's simple a N9500, but I guess I need to double confirm. How can I be 100% sure ?
Second, current my version shows N9500ZHU4DSE7. From what I have read, it should be bootloader 3. And normally I should be able to downgrade back to Oreo. I am just unsure how, and which firmware I should use.
Also if I downgrade, will I lose the phone internal data ?
Only reason why I NEED to downgrade : the software block to prevent using 2 sims and one sd card !

"N9500"ZHU4DSE7 is SM-N9500
N9500ZHU"4"DSE7 is the bootloader version. You are on ver. 4
You can't go back to bootloader version 3 or below! Bootloader won't allow it!
Fine the last oreo bootloader ver. That has bl. Ver 4 in the firmware.
Yes you would lose your data going from pie to oreo!
The last oreo firmware is N9500ZCU4CSA1 look on sammobile.com for your model and firmware.
Thank you for confirming what I also managed (in the meantime) to confirm.
Losing all data is a NO go for me

If you are on the latest firmware with N9500ZU"5".... you can NOT go back to Oreo!
Or if on N9500ZU"4".... try this below....
Did you try factory resetting your device before flashing that firmware.
Use all 4 files, AP, CP, BL, and with the CSC file (not the home-CSC file).
Hi guys. I bought an unlocked Sprint LG V40 (V405UA). I am from Argentina and it works perfect in my country with my SIM card, but the problem is that it has the Sprint firmware and it is in Android 8.1 and it won't update if i am not with Sprint contract i think. I'd like to have the stock global firmware and get OTA updates (Android pie at least). I see a page called "lg-firmwares.com" with all models firmwares and tutorials, but i am noob in this matter and i don't want to "brick" my phone or lose the unlocked condition. If i follow the "lg-firmwares.com" tutorial and flash the Android pie firmware for my model, can i brick my phone or lock it again? or it is secure and everythink will be ok?
Thanks.

Okay you have 3 ways to do this.
1st. If rooted/Unlocked Bootloader: https://forum.xda-developers.com/lg-v40/how-to/guide-crossflash-unlocked-pie-to-t3944359
2nd If rooted/Unlocked Bootloader: https://forum.xda-developers.com/lg-v40/how-to/guide-make-lg-v40-compatible-lgup-t3953120
3rd I personally haven't tried this yet: https://forum.xda-developers.com/lg-v40/development/lg-1-16-t3967559
With the 3rd one you should just simply be able to flash any KDZ but you should make sure it's compatible first.
But once you Crossflash no more OTA's you would have to download NEW KDZ and flash it over the one your on.

https://forum.xda-developers.com/lg-v40/how-to/guide-lgup-root-t3967858 This Guide i made should help you with your 3rd question. That we have seen no you shouldn't loose Sim unlock if it's factory unlocked or if you carrier unlocked it for you after so many months being active with them. You always loose your data when KDZ flashing. You wont get OTA updates if you Crossflash...if you stay with your current rom OTA's should be possible
If you're using a us carrier phone outside of the us, you should just forget about ota. It won't work. Do yourself a favor and learn about the various flash methods. You're gonna need one of them at least to keep it updated.
Thanks guys. It sucks that it's imposible for me to get OTA updates, but at least i can try flashing my phone to keep it updated. I will check the guide and learn more about it then. Anyways i think this is an amazing phone and a bargain for the price nowadays..
I have android pie

Hi guys. I bought an unlocked Sprint LG V40 (V405UA). I am from Argentina and it works perfect in my country with my SIM card, but the problem is that it has the Sprint firmware and it is in Android 8.1 and it won't update if i am not with Sprint contract i think. I'd like to have the stock global firmware and get OTA updates (Android pie at least). I see a page called "lg-firmwares.com" with all models firmwares and tutorials, but i am noob in this matter and i don't want to "brick" my phone or lose the unlocked condition. If i follow the "lg-firmwares.com" tutorial and flash the Android pie firmware for my model, can i brick my phone or lock it again? or it is secure and everythink will be ok?
Thanks.
