[Q] Tried to downgrade to MF9 after upgrading to MJA.

So... I did the stupid thing. I attempted to go back to my old MF9 backup through TWRP after upgrading to MJA, and now my wifi won't even turn on. I've been trying to figure this out for a few hours now, trying various fixes. I've tried to use ODIN to flash back to complete stock, but that just destroys my phone until I flash a recovery through ODIN. Everything I've seen on the forums so far has made it seem as though there is no hope since Samsung added in Knox.
I'm sorry if this has been resolved elsewhere, but I've literally been searching the General. Q&A, Android Development, Original Android Development, and Developer forums for several hours today with no luck. Can someone please help me with this? I just want my phone to be fully functional again...
EDIT:
Here's the deal; my main problem was with Wifi not working. The Stock MF9 Kernel was not working, but the 4.2.2 TW Kernel found here finally did.

did you try this?

Yes. Nothing changed when I did that. I suppose that I should call out that I am currently on MF9.

i just gave up on trying to do a restore. I actually used Titanium to get as much information from my old backup as possible then just rolled with it. I know that probably isn't what you wanted to hear but that what worked for me.. hope that helps

I have read that the WiFi issue may be a Kernel issue.. Did you try a different TouchWiz kernel and see if it worked out?

This is actually what I was trying to do, sadly. Titanium was backing up my info to the phone storage rather than the SD card, and I had to do a data wipe to get to MJA, so I lost them. I figured I could restore to my MF9 backup to redo them, and that's when the trouble started.

I finally got it working. I had to try several different kernels until one finally worked. Now about flashing a new ROM...

What kernel did you use and how did you install it? I'm having a similar issue and can't find a fix.

Scott, check my first post. I edited it with a link to the page with the kernel I used. Make sure that you choose the correct kernel for your Android version. The MF9 and MJA designators have nothing to do with which kernel you need, so make sure to check in your "aboout phone" section to find out what android version you're running. Using the 4.3 kernel on 4.2.2 will cause a bootloop, which is easily fixed by flashing the correct kernel.

[Q] LG G2 D802H, Root help.

Hey guys.
I am not that new in the whole rooting "scene" but it seems that I am unable to find a proper guide for rooting my (updated) phone. Every guide I have found, not only in this site, is outdated for like a year or so or just for older versions of the firmware, and if there is one thats for D802H(international model, I'm from Greece) it's probably in really bad english or directed towards pros. I rooted my G2 when I got it last year but decided to unroot because of some problems with the screen so I could use my warranty and haven't rerooted since. So it would be really helpful if any of you could point me in a certain guide or just run me through the whole process of rooting my phone, what to download, what to do to my phone, the recoveries etc. I would really like to use Cyanogen Mod or a G3 mod. Certainly, my choice for these two is because they look awesome. If you have any other rom on your mind that might be better than these, please dont hesitate from telling me. I really need all the help I can get, last time I got stuck on a boot loop and didn't know what to do for many hours before I reflashed to stock. So basically I would like a root guide ( found one from a member called somboons, seemed nice but wasn't really thorough as to whether I should wipe all data or just wipe dalvik cache and really wasn't noob-friendly) and a link to a ROM download page with a guide for flashing it. Not really into kernels, so if you could suggest a different one from stock that provides better battery life etc. that would be great. Any other info that you feel I should know will be appreciated.
Thanks in advance guys and sorry for the trouble I'm putting you,
George.
P.S.: Would like to avoid wiping data if at all possible.

Oh well that was easy, thanks man. Rooted succesfully, installed SU and now have TWRP. What about the ROM? For CM, should I just go in their site and pick one for my phone? Is a release here that's stable?

Problem with OP2 after brick

Hello,
I have a problem with my OP2. And I hope you might be able to help me with it. The main problem is that I am not able to get fingerprint and camera + flashlight wirking at the same time, at any ROM. I have tried a lot of different ROMs but non of the seem to work. In all the cases it is either the fingerprint that works, or the camera + flashlight. I didn't have this problem before the brick.
All of the problems started when I my phone got bricked. I used a recovery tool (Qualcomm) in order to get it working again( with TWRP recovery). But when I installed OOS 2.2.1, only the camera and flashlight work.
But when I install OOS 3.0.x, and afterwards CM 13, the fingerprint works, but not the camera and flashlight. I have tried everything I can think of at this moment. For example I have tried to changed the kernel. I have installed the recoveries and ROMs in different orders. But at the moment I have no idea how I can get it working properly again.
I hope you are able to help me out,
Rhardof

i think you should restart your device

What Rly? Restart the device?
Anyway why dont you use the stock images that are posted here and flash then over fastboot the komplett device every Single Image?

Oke I'll try that. But where exactly can I find these stock images? And should I replace all of them or should I just replace a couple?
Thanks a lot already!

Moto X Pure help asap

What do you mean by it just stays open. Do you mean it never boots? Like a bootloop? If so, search 7.0 ROMs bootloop, you'll find the solution, tons of threads on the help and q&a here. But if you don't mean what I just explained then could you clarify?

Sorry for not being clear, i dont think it is bootloop. It boots into the rom no issues and i can use it normally and doesn't restart till a few minutes no matter what rom i flash.

If I were you I would flash back to stock and make sure you you don't have a hardware problem, If nothing else it's a chance to start over. I haven't gone to custom roms for these reasons, mine is my daily driver to and I can't afford to get caught without it.

No worries. Yeah I don't know what the issue could be, could be a ROM issue, it's weird though, but like the poster above me, it could be hardware failure and flashing stock would be a good way to find out.

I would love to go back to stock but how? All the tutorials are very hard for me to follow can you guide me to an easy one or tell me how?

I agree that they are a little hard to follow, I looked at them myself and it looks like the quickest way would be to go back to 6.0 and upgrade back to 7. But someone else could correct me on that.
For future reference, it's best to always twrp backup your stock rom before doing any kind of major changes especially custom roms. That way you can always fall back to original if something goes wrong.

I would go back to stock 6.0, if he hasn't upgraded to 7.0, I'll do some digging, find good guides, and post them here in a bit @Philo0o!

Yeh before i started flashing roms i was on stock 6.0, thank you so much

I think I might also do a twrp backup of my 7.0 and make it public, but it will take me a couple of days before I can factory reset. There doesn't seem to be any stock 7.0 backups around on xda.

Alright if you wanna go the custom ROM route, don't update to stock 7.0, not many custom ROMs work with it's new firmware. I'll get you a guide to go back to stock 6.0 then!
Edit: Alright @Philo0o, here's a good page with all the firmware links for your phone, and the commands to flash the firmware are there for you. Let me know if you have any questions about that.
Also, when your ROMs aren't working, what are you doing to try again? what I mean is you could try a full data format in twrp. Not just a wipe of data, system, etc.. A full format isn't quite like going back to stock, but it may help if there are leftovers somewhere causing issues if that makes sense.
so if you wanna try a full format, backup your internal storage to a computer, or to an sd card, and then format, and then you will have a clean slate, move what you need back over to your phone and voila!

Ill look through that tutorial, and whenever i flash a rom i do a full a wipe

GSI ROM (RRemix) Refuses to recognize that I have a SIM card!

Hello again all!
So I've recently discovered the glory of GSI / Treble roms! Good stuff! But after much banter with Ressurection remix's 9.0 GSI rom, I have still yet to get it working, and wasn't sure if I'm just missing something.
So far, what I've tried is:
- Wiping everything (caches, system, data) as well as formatting my data partition
- then installing the rom. after a couple of routine-looking reboots, the system boots without gapps functioning great.
- quick settings states 'No SIM card', which is false
- reinstalled rom countless times
- restored to functioning rom, backed up EFS, reinstalled RRemix in the same fashion, restored EFS backup. No solve there.
And with that, I'm out of ideas and without much knowledge of GSI / Treble processes, I'm not even sure how to word searches for help. Any advice ya'll?

Hey man, let me know if you still haven’t gotten this resolved and are still looking to do so. After days of research and experimentation I finally created a process to reliably flash a fully functional RR 7.X rom. I can provide my boot.img and instructions if you need them.

It’s funny you should reply to me on today of all days. This morning, after a month of testing, I finally succeeded in getting my RP2 to A/B boot RR 7, TWRP, AND have it rooted with Magisk. I couldn’t believe I finally got it. AMA

Did you try an A only image? It should work as it doesn't touch the vendor image or CSC. At first I was trying AB images on my Note 9 and could never get signal. I found out that we are only supposed to use the A only images on that device and my problems were solved. I haven't tried anything on my Razer Phone 2 though as the stock ROM is pretty much exactly what I want. It's worth a try.

Need RR help.
