[Q] flashing roms back and forth?

Ok, so I've been doing a lot of reading, and would like some confirmation for if I understand this part correctly, I had a hard time finding anything on flashing rules for the moto g.
In general you can flash any rom stock or custom back and forth as long as you stay within the same version number or you can update, but no downgrading, am I right? So if I have a boost moto g with stock 4.4.2 and I flash to Verizon stock 4.4.2(for pageplus) or CM11(for custom rom) I can then turnaround and flash boost stock 4.4.2 and everything will be fine? as long as I don't upgrade to 4.4.4 in which case I would be fine as long as I stay within 4.4.4 roms?
Please let me know if I understand this correctly, and if I missed any small but important details that have to do with rom flashing.

no problem bro, happy to help

Actually you can't downgrade from 4.4.x to 4.3 because the bootloader is different and if you try you'll brick your device but you can flash any rom back and forth if is based on 4.4.x because the minor release are just small bugfix to the system. So actually what said theonecallednick it's not totally true.

[Q] D850 Issue (accident)

So here's the thing. I accidentally put Sphinx Rom on my D850. The rom is only for D855. Now my mic and headset do not work. I have tried to flash back to stock rom, but it won't let me since it believes my phone is an D855 now. Anyone have any ideas?

This is just a thought, but maybe you could check your build.prop and compare it to that of an untouched D850 and mirror that on your device / look for any differences. I have used this trick to fool certain apps/etc to install by making them think one device was another device, for example, installing tablet only games on a phone. I am not sure if this would remedy your situation and allow you to return to stock, especially with our current bootloader situation making it all the more difficult.
I guess one other option would be to get it replaced under warranty, without being "untruthful" to your carrier of course... Just play dumb
Just food for thought like I said, and your mileage may vary.
Maybe others can chime in and add some other thoughts.
Good luck!

Hmm. I'll try searching.

All, correct me if I am wrong but I believe that the D855 is the international version, while the D851 is the T-Mobile version.
OP said that the ROM was only for D855.
Thoughts?

The title specifies a d850 not a d851. The d850 has a locked bootloader therefor you cannot install a custom recovery let alone a rom. I dont care if the rom was a d855 or d851 or for the d850.

I'm aware... I was clarifying the difference between the D851 and D855. I am well aware of the locked bootloader.

OK I'm confused, why are you even talking about a d851 at all? The 2 devices that the OP listed was a D850 and D855. We all all aware of the differences of the devices that is why we are questioning how he flashed anything on the D850 in the first place

Because of the first quoted post above... Does everything have to become an argument these days? I was clarifying for that individual, and it clearly says "Tmobile"...

Number one who is arguing that person was still asking how to flash a rom on the d850. Just relax no one is attacking anyone i was just trying to understand your post.

He didn't. It's virtually impossibly without unlocked boot loader and custom recovery. If he had it would have rendered it unbootable.

[Q] Which recovery to use to flash Of Cyanogenmod 12 on a GPE 5.0.1 converted XT1033.

Afaik, therr is no recovery compatible with GPE 5.0.1 fully. We need the kernel sources to make a recovery compatible with it.

Can you please give me another method to flash CyanogenMod 12 on my GPE 5.0.1 converted XT1033?I shall be grateful to you.
Thanks a tonne...

You cant try the method cyanogenmod asks its users to follow [here]. They link you to some cwm recovery. This is a technique which I can not guarentee will work and i suggest you try it out only if you are fairly acquainted with messing around with your phone and fixing soft bricked devices.

The recovery in that page is pretty legacy (02/2014)... Most likely won't work.

The recovery does boot. I tested it on my device just now. But as you said, since it is pretty old, it shouldnt work further.

I am not addict to custom roms but if you need anything from an owner of a rooted H955 v15c just mention it.
By the way, are you planning custom rom for all models?

yea good luck with locked bootloader.

If you need anything with a rooted 15e (latest lollipop version) image, I can help. Also, how are you going to flash a ROM with the bootloader locked in marshmallow, since bootloader locked in mm = no root and no flashing ROMs? But still very good initiative, I'll look forward to see your progress on the ROM. Nice idea C:

We will give you all our support~

i will try to root mm first

Do it, do it now

i bricked send it to lg and i hope it will get fixed by warranty as far of lock boot loader the phone failed while flashing rom and the partitions where changed so when i was flashing stock Rom was stuck at 9 percent on lg up and i read on forums a lot have the same problem maybe i will not root again lg g flex 2 stock marshmallow to be safe in my other phones the rooting process was easy now i dot want to brick it again sorry guys il try to make mods from v10 for 5.1.1 nothing more for you guys me i will not use it im guess root break this phone partitions so sorry

Well, at least you tried. Thanks for that. If you ever decide to look into unlocking the G Flex2's bootloader, make sure to update us

lets just hope for 7.0. I know LG firmware can get up to v30. so far we have v20 mallows

... oh really ? and how exactly can we do that? It would be great if you could explain it, because everyone here is actually waiting for that to happen !

Flashfire may work at least backing up all partitions.
I believe it still needs a custom recovery to flash but I haven't gotten my device yet. Will be here in a few days.

Has anyone gotten OOS 12 on the IN2019 (Verizon OnePlus 8)?

Been looking for a solution to convert this device to the global variant successfully with the modem working or to get Verizon to release the update. It's been one year since Android 12 has been released and it doesn't seem like OOS 12 is coming anytime soon, so if anyone knows how to get the modem working on the global variant, I'd be glad.

The hardware and kernel source are fundamentally different on the Verizon model. Even if you somehow got global firmware installed with working data, you'd have a lot of other bugs and glitches because the hardware isn't compatible with the Global OS.

It works quite well. on the V model (that's what I have). but you need to back up your modem for data. It's best to reset to 11 factory. Then you can run ROMs that are OS 12.

I believe he means that you can run Android 12 ROMs, not custom ROMs, unless I misread?

I did not use a specific guide. I have been rooting the phone for some time and found that I could flash os global using a fastboot flash ROM. If you root your phone and save the stock os the 11 modems you can replace it in the global rom.
I will correct myself and say that I don't remember for sure if global will work (for modem replacement) but you can get custom ROMs to work well with that method.
I would have to go back and sort through for the links or try again to be sure. But if you know what you're doing, it is pretty hard to brick the phone. So play around with other guides. (with your own risk and discretion involved).
You can even run android 13 on the V model( not good IMO. buggy).

Stock modem does not work. That is for sure. I've moved to the pixel 7 Pro so I won't be messing with the one plus anymore.
