Sorry but what are you on about? Android 7.0 hasn't even been released for this device yet....

This is all well and good but as stated by Alex Android 7 isn't out for S6 edge + yet. And I'm pretty sure when it does come out it will change the boot loader and reverting back to 6.0.1 will cause imei and baseband loss.

If it came out but not officially since the rom filter is that of developers

I was on Nougat multiple times (Khongloi S7 port ROM and DevBase 7.0 ROM modifications), returning to MM was as easy as going to TWRP and flashing a MM ROM, without any bootloader business involved... In my case I simply flashed the V15 Note 7 port by Khongloi, and I was back on MM without any bugs or problems. And if you didn't notice, the firmware in this guide includes a bootloader, so even in the case of the bootloader changing with Nougat, there would be no issue reverting back. I've downgraded my Note 4 from Marshmallow to Kitkat multiple times (for testing purposes), and it's as easy as doing the same steps that are provided in this guide
Go down to the development section, you can see that there are multiple Nougat ROMs that exist for this device already, all based on a leaked base ROM that was meant for app developers. The ROM is nowhere near to finished, it drains battery and the performance is poor, and for that reason many users will consider downgrading, and this thread works for that purpose

No, the performance and battery life ratio really is worse in the ROM, it doesn't benchmark even close to stock MM and battery drains fast on some occasions

This might be due to the fact that they are ports of 7.0.
Im just warning people that update to official when it comes out that it has been known that it updates files that once done cannot be reverted back or it will cause problems, one being the null baseband/imei.
But yes, reverting back at the moment is as easy as flashing a 6.0.1 rom or stock firmware.
Either way hopefully people back up their efs!

i updated to an official 7.0 firmware and now i can't flash 6.0.1 bootloader. Any ideas or am i stuck at 7.0?

Well hopefully people will back up their EFS which is a MUST do before starting to flash roms etc.
If you have I think you can use odin to go back to 6.0.1 and then restore the backed up EFS from that version of Android.
Other than that you're stuck on nougat roms.
If you have reverted back to older and you lose imei and/or baseband then you'll need to reinstall nougat rom to get the imei/baseband back.
But as I haven't flashed an official nougat rom I can't say if this will all work or not. I'm going by past experience when I did this with jellybean - kitkat on my old phone.

BLN-L24 links have bad key in the Honor 6x Repository thread

Need to rollback, or be advised of any custom ROMS that work..

Try Elite ROM from ROM section. it should work fine.

I personally would not recommend installing Elite ROM as it is more hassle than it is worth when you try to switch ROMs. It re/debrands your device and even after restoring a nandroid your audio will not work nor will your camera function properly. What files have bad keys? I put a lot of those up and the keys should work fine....
@shashank1320 check the links in the BLN-L24 section....something got messed up when you copied my links as mine work.
@ghostair is your device bricked? IMO none of the ROMs for this phone are worth installing on a main phone because there is too much functionality lost, no disrespect to the devs. Elite ROM does have the least amount of bugs but it is a hassle as I mentioned earlier. My main gripe about it is when installing and uninstalling apps you must restart the device in order for the apps to be added or removed from the app drawer....its a major annoyance.

Let me check mate. Thanks for pointing that out.

No it's not bricked, actually I am on TWRP 3.1.1-0, it was only EliteROM's version that didn't work. I haven't even been able to use the phone at all, for a week, and am currently on LineageOS 13 as it was only release that works for my model it seems.

Im confused....your original post says you need to rollback but you say you are currently on LOS 13?? Rolling back refers to downgrading from Android 7.0 (Nougat) to 6.0.1 (MM) but you are already on MM if you are running LOS 13. You also say your device is not bricked but then in the next sentence say you havent been able to use it at all for a week.....and lastly you say LOS 13 was the only release to work for your model yet every single ROM in the development forum can be flashed to the BLN-L24, I know because I have done it.
What exactly are you trying to accomplish here? Your posts are contradictory and make no sense. Id be glad to help but you gotta give me something to work with here.
Im assuming you did not make a full backup in TWRP before flashing any ROMs, in which case you have learned a valuable lesson....always have a backup. But since you dont we will get you back to EMUI which I assume is what you mean when you say roll back.

I understand, I probably should have just used, "go back," to EMUI. Since LOS 13 isn't usable in the least, as I can't make calls, and it drops LTE.

If they work then how? I followed everything, flashing vendor.img with fastboot, then flashing the respective zip?

I'd rather not go back to EMUI, it's why I haven't been able to actually "use it as a phone," since purchase.

Why would you not want to go back to EMUI? Its smooth and everything works. EMUI is the reason you havent been able to use it as a phone?? There is not one single ROM for this device that works entirely and has full functionality. You're always going to be missing something whether its the camera, LTE, calls, etc.
You're going to have to go back to EMUI so you can update to Anrdoid 7.0 (be sure to make a full backup) and then flash away all the ROMS you like and you will see they are all broken in some way. This is most definitely not the phone to use if you are looking for polished ROMs.
My last tip before departing......download the flashable vendor zip if you still want to mess around with the ROMs, it makes life much easier. Its in one of the threads in that forum I think AOKP

Upgrade from Nougat custom ROM, baseband update, Treble - Need some Help please

Hi Friends
I have been using crDroid 7.1.2 on Zuk Z2 plus for last 1 year almost. Tried a few ROMs at that time and settled with crDroid. Did not get much time after that due to hectic work schedules.
Now, I am planning to upgrade to a stable Oreo Rom. AEX and Jaguar seem most popular, but I would experiment with few others like crDroid as well.
However, I have few concerns and doubts where I would request your guidance and help. I did some research myself and went through lot of threads but still some questions remain:
1) I face two irritating issues on my phone. Not sure if it is a device issue or ROM or baseband issue:
a) While on speaker on a call, the person on the other side cannot hear me clearly. My voice is extremely distorted.
b) Same happens on call recordings even without being on speaker. My voice is totally distorted in all call recordings.
So, someone suggested me to update baseband by flashing ZUI 1.9 and subsequent versions. My current baseband is 1.76 Indian. Multiple doubts on how to go about doing this safely and efficiently:
a) Do I need to flash complete Chinese ZUI ROMs in this sequence? 1.9 -> 3.5 -> 4.0? Does the 4.0 ZUI support VoLTE?
b) How to flash these, QPST, TWRP, QFIL - See different options mentioned in different threads.
c) Also, saw some directly flashable baseband zips without the need to flash ZUIs or to flash baseband 1.70 chinese first.
https://forum.xda-developers.com/le...oreo-firmwarebaseband-twrp-flashable-t3776254
https://forum.xda-developers.com/lenovo-zuk-z2/how-to/baseband-radiomodem-z2-plus-twrp-t3749988
https://forum.xda-developers.com/showpost.php?p=75584934&postcount=9
Which is the latest and most stable baseband version. I understood that the baseband version number doesn't change but there are updates on each version of ZUI.
How to fallback to 1.76 Indian baseband in case something goes wrong.
Please suggest what is the best and safest approach. Not much awareness of usage of QPST, QFIL etc. Used TWRP before for flashing ROMs. Do not want to end up bricking my device.
2) If I flash these Chinese ZUI ROMs, I guess the bootloader will be relocked? I have the unlock_bootloader.img which I originally used to unlock the bootloader. Guess, that can be reused to unlock it again. Just wanted to confirm, no other complications here?
3) About Treble and Non Treble TWRPs and ROMs, which one is preferable? After flashing the Chinese ZUIs or directly flashing latest Basebands depending on outcome of point 1, I believe I will have to flash the latest TWRP (Treble / Non Treble). Also, accordingly I believe I will need to change the partition name: Factory2Vendor ?
4) Which ROM and Kernel combination would you suggest. Priorities are No bugs, good Battery life, VoLTE, Less heating, Smooth UI and customizations like in AEX / crDroid / RR etc. Gaming is not priority.
Also, in my current crDroid Nougat, although Magisk Hide, hides the root from most apps but some apps like Google Tez, Microsoft Intune Company portal etc detect the root and does not allow usage. I need to have my official mailbox setup via Microsoft Company portal and Outlook. Which is not allowed on crDroid Nougat with Magisk but works fine on my Moto G running on Lineage OS 7.1.2 (Unrooted).
5) Finally, anything else which I might be missing or not considering? Please suggest me high level steps for the above. Specially for point 1.
Kindly help.

I didn't read the whole post as it is really long.
But I understood it is about baseband.
You can flash the baseband and other firmwares from zui 4 without any problem via twrp itself.
But as far as I know 1.76 also works pretty well.

Thanks and Sorry for the long post. Not only about baseband, but I want to upgrade to an Oreo Rom.
Someone suggested to change the baseband as well as I am facing following two issues:
1) If I put the phone on speaker while on a call, the person on other side cannot hear me clearly. Extremely distorted voice.
2) My voice is very distorted in all call recordings.
So, I thought I would try updating the baseband by ZUI chinese flash incrementally.
Kindly check my main post and suggest the steps.
Also, if the chinese baseband doesn't works well, how can I come back to 1.76?
But as you suggested the latest baseband can be directly flashed using TWRP, shall I flash this:

Keep the same baseband and update to oreo.

No. Not yet. Still on Nougat old custom rom from last year. If I have to flash ZUI then Factory to Vendor has to be done later I believe? That's why waiting to get more advises from this thread before deciding the course of action

This is my current setup.
This rom used to give excellent battery life and deep sleep earlier but now loses lot of battery overnight. Always awake

Don't flash zui.
Follow this guide
https://forum.xda-developers.com/lenovo-zuk-z2/how-to/z2plus-treble-roms-flashing-reverting-t3778287
Then you can install both treble and non-treble roms.
If you want to go back to zui then you can qfil without any issue.
Cheers

Best Gaming Rom One Plus 3 2020

Hi guys,
I'm starting this thread hoping it will help someone. I personally searched all XDA and Google for an answer as I play heavy games one of them is Free Fire. I like playing the game at MAX FPS and Graphics. I was on the latest OOS 9.0.6. It was awful to me. As i got game lags and my phone got extremely hot. That's when it ventured in the search for the best rom or stock firmware to give me the best performance, stability and battery life. My battery life on 9.0.6 was really poor. I had battery drains of about 10-12% on idle overnight. I searched everywhere and all the threads were outdated and I needed a recent solution to my problem. I mean there's been a lot of newer One Pluses after the 3. But for the hardware that it has I was sure I could get more off my One Plus 3.
I tried Havoc , Evolution X , CR Droid, Lineage OS, Pixel Experience and all the OOS that where rolled out for the one plus. Yes I did alot of flashing and formatting. Since I never flashed just the OTA. I always flashed the firmware on that version and did a clean install always since i wanted a final verdict and didn't want to have a doubt on the dirty flashing. I used each rom and Stock Oxygen version for 4 days since i wanted to give the battery a couple of cycles before getting my final verdict on the rom.
I wrote the SOT time for every firmware or Rom that I flashed to not forget.
Finally I wont disrespect any rom developer out there saying there rom isn't good. As I for myself wouldn't be able to build one. Less without being paid. On the contrary I would like to say a HUGE THANK YOU!!!!!! to all the developers that take their time and build roms for us. I greatly appreciate every Developer here at xda. A big round of applause to you guys. You all are great!!!!.
All the roms are awesome and unique. I'm pretty sure it suits many, many, many users out there. As we're all looking for something different and different features in roms.
I tried all. And TADA!!! I'm on Oxygen OS 4.1.7 Android Nougat. Yes its far from the newest Android Version But the battery life on Idle is the best I have 0-1% battery drain overnight on idle with WiFi on all night. Game performance is awesome. I play Free Fire at Max FPS And Graphics with absolutely no lag. I use Whatsapp and Facebook Messenger and camera all day for my work and i'm able to reach back home after 8 hours work day with an average battery of 67%. To me it can't get better than this. Second in of the OOS was 4.5.1 a little better performance but battery drain was little higher. To me the exchange for a little performance difference to higher battery drain wasn't worth it. Again this is just my humble opinion and experience. Your results could be different. If you want to know my procedure and settings to get this on my One Plus 3. Feel free to ask. And as soon as i have a little time i can reply. Thank You XDA for the Best Forum on planet Earth.
Best regards,
Chimpzilla

Hi Chimp, thanks for writing your experience here. I had similar experience but used OOS 4.5.1, now want to switch back to OOS 4.1.7 but not finding any download link for it. Can you please share if you have any.
What do you suggest, using MSM Tool to restore to OOS 4.1.7 or just flashing it through TWRP on unlocked bootloader?
On OOS 4.5.1 I was trying to use Advance Kernel Tweaks but Magisk was not working with ElementalX kernel so gave it up.

Okay Guys. Sorry have been really busy. I installed with unlocked bootloader and TWRP. Wiped everything except internal storage. So that Custom Recovery gets replaced by Stock Recovery. Then I booted to system. And then back to recovery just to make sure I had Stock Recovery before Relocking bootloader. Once I had confirmed that i had stock recovery I booted to fastboot and relocked bootloader. After relocking your phone will be wiped please backup anything thats important to you. Every locking or unlocking of bootloader will wipe your data. Im not responsible. Once bootloader locked I booted back system. All firmware downloads can be downloaded from oneplusupdates website. Hope this helps.

Flashed 4.0.3 through MSM then used local update for 4.1.7, setting up my apps now.

adb shell

I was actually on OOS 4.5.1 lol older version are better sometimes than the new ones and not everybody know that i downgraded to 4.1.7 now and im testing it right now because i have nothing to do in home with this problem of virus...

Believe me, you won't want to. The update has been pulled. It still has so many bugs. Biggest problem for me, I was curious that it, and updated, A12 currently has no local update option. Means roll back is not possible, only with the MSM tool. Then it starts all over with rooting again.

you can download and install this system update apk from oneplus and it gives you the options to rollback. But be aware rolling back will wipe your device.

You can you the apk on ColorOS to rollback also.

Which bugs are you facing?

Yup, and i've been using it for a month now.

I updated to A12 in Dec when the first OTA was pushed. I had too many issues even after the first 2 patches, downgraded back to OOS11 and never been happier.
I'm waiting for 10pro to launch so I can update to OOS12 then

I played around so much, that I don´t remember everything now. Some apps didn´t work. I think, but I´m not sure, I had problems with Viper4Android. Or it was Youtube vanced. Sorry, I really forgot.
Certain setting options had been missing for me or were no longer where you would have expected them to be. I also missed the local upgrade, but that problem has been solved in the meantime (I was not well informed). I was also not happy with the UI, but that is not a bug but a matter of taste.
In sum, not so dramatic, but my evaluation has coincided with those of other forum members. Does not mean that I am right. I'm happy to be corrected.
How is the general satisfaction with A12 here?

A few months back when they started pushing Android 12 I was eager to try it and so I used "Oxygen Updater" from the play store to download a full stable version of android 12 but i accidentally downloaded the Indian version. I had so many bugs on it, but then I used the same app (oxygen updater) to switch to the EU version and my phone worked perfectly with no bugs or anything. I have now switched to Pixel Experience rom and wifi is not working so I may go back to Oxygen 12. But yeah if you have bugs on Oxygen 12 then use Oxygen Updater and download a new version to flash and your bugs may vanish.
Enjoy

I was curious about A12 and gave it a second try after cleaning up everything.
Does Viper4Android work? Just trying with a fix but not sure if it will work.
The next thing is that file manger doesn´t appear in Magisk, when u want to install a module from internal storage.
At least Youtube Vanced is working now.
BTW, post above is ColorOS 12

Another question: how to us the "OnePlus 9/9Pro Rollback APK". It´s a zip file. Unpacking shows now apk file. Flashing through kernel manager of course not possible. Sorry, don´t find a way to install.
Second try of A12 was not satisfying. When I use the MSM Tool I´ve to re-root again....
Edit: renamed the file to apk at the end. Did it once without success, don´t know why. Now it works

Hope you figured it out. If you haven't.
- download appropriate downgrade package and move it to the root folder of your phone.
- download and install https://oxygenos.oneplus.net/OPLocalUpdate_For_Android12.apk
on your devices... this allows you to access local upgrade... if your phone doesn't install a shortcut you can keep reinstalling it every time you need it
- open OPLocalUpdate_For_Android_12.apk click gear in top left corner and install the downgrade package you put in the root directory
You can also use the local update to install other OxygenOS12/ColorOS12 packages. I just went from C.36(Global) -> C.38(EU) -> C.46(ColorOS12) then rolled back because MMS is broken at C.44 all variants of both OSs and above... at least for me.

Thanks, my problem was that I didn´t know that I have to rename the files. Many thanks!

Personally, I'm pretty satisfied with the C44 update for OxygenOS 12, stable and smooth, as intended. But yes, the first updates were messy.
For having given a try to ColorOS 12 too, OxygenOS 12 gave me a better experience on the OnePlus 9 Pro: less throttling in games and less bloated.
If we get a ColorsOS C44 EU (which should be far more debloated than its Chinese counterpart) that isn't making games throttle, then I'll surely jump into the wagon, but for now, OxygenOS 12 remains the better option if you want an Android 12 official experience for your phone.
