trying new roms and messing with my phone, would really like to be able to flash Nameless or PE. I have seen that if you get the TMobile variant things get a little tricky with firmwares and phone versions. I got my SIM unlocked and I already have my unlock file to unlock my bootloader. Havent done that because I dont really know if my ROM flash would work.
Do I need to unlock my bootloader?
Can I already flash my ROM files directly from adb or do I need to convert my phone to EU with TSM?
I have seen that people mess with modules that I need to backup, is this only needeed to convert to EU version or would I need this for Nameless
?
Do I flash firmwares via fastboot/adb or do they come with local updates? Which I do not have because of TMO.
I have already asked a couple questions in the forum but I need to clarify myself with ROM flashing and prerequerisites with my 2127 version. I would really appreciate some help about this, Ive never tried getting help from forums and looks like this phone community is pretty active.

Go to the Nameless thread and follow the instructions to the letter and you will be fine!

Is it really that easy? I do not have to do anything else before because of TMO?

No, just make sure you follow every step in sequence. Read the instructions a couple times to make sure you fully understand everything. Like are you suppose to be on Android 11 or 12 as an example.

Bricked HTC One M9 (managed to install TWRP 3.0)

Hi, forgive me if this is not the correct place for this but I am at a dead end with my struggles. I have an HTC One M9 that I managed to delete the OS & Recovery. I finally managed to get TWRP 3.0 back on it and when I try to install the OS (ViperOneM9_6.0.0) & Gapps it goes into a bootloader loop. All goes well throughout install process but I just cant get it to work. Can anyone PLEASE point me in the right direction, I've been w/o a phone for going on 3 months now.
P.S. If it helps at all it says developers edition and my carrier is MetroPCS (Tmobile)

I suspect that your firmware is out of date. Please post your OS version - that will help us know how to advise you.

Thank You. It doesn't have an OS Right now, could you be more specific about what you would need (format of the info possibly, or an example. I am fairly tech savy but have very little android internal experience)

Your OS version will come up regardless of whether you have a ROM installed. Check out the readme thread for how to use fastboot to pull the information.

xiaomitool. No more bootloops

Like many of you, I also had the problem that the phone had a bootloop after a flash. No matter what I tried, nothing worked. I found and tried this tool xiaomitool from Francesco. With this tool you can flash any rom without bootloop. Please save your data before
Thus tool does a flash completely automatically. You even didn't need TWRP pre-installed on your device

Hi,
First, I'd like to thank you for finding the tool and publishing it here.
It's a really handy Application.
After moving around in the app quite a bit, I couldn't find any way to install any custom roms.
All it offers - Miui Global/Beta, Chinese Official/Beta roms and some other tweaks (TWRP, SU etc.)
How to flash any other custom Rom..?
Am I missing something here..?
Please describe.
Thanks in advance.

You have to download the ROM, then go to: "Local ROM file"

Rooting question N910v just purchased. Can I rooting?

I have read countless post and have been to a dozen websites and I guess I am just confused if I can root this device with the current status, software/updates and security patches.

Yes, you can.
It requires unlocking the boot loader and installing a custom recovery. There are a few threads about it which makes it somewhat confusing. What it boils down to is do you want to use LL or MM to unlock it and once that is done do you wish to use the stock TW LL/MM or a custom ROM (TW/AOSP based).
Easiest to follow instructions here, uses LL to root:
https://forum.xda-developers.com/no...asy-guide-how-to-root-verizon-galaxy-t3454593
The hybrid way (LL/MM software mix, will require working SIM/Data connection to complete rooting), once done will be full MM based:
https://forum.xda-developers.com/no...t/howto-bootloader-unlock-upgrade-to-t3398144
https://forum.xda-developers.com/note-4-verizon/general/shortcut-to-rooted-n910vvru2cqi2-t3763451
IF you want to run a custom rom, unlock the bootloader as outlined in the links above, install TWRP and then the ROM of your choice (TW/AOSP).
I just did both ways above not too long ago on a new to me 910v, then I ended up using the files from this post on the modified/hybrid way to root:
https://forum.xda-developers.com/showpost.php?p=76813374&postcount=16
Then I upgraded the partial firmware from here to CQL1:
https://forum.xda-developers.com/devdb/project/?id=15720#downloads
Yes, that means I wiped and rooted all 3 ways linked/described (BPA1, CPD1 & CQI2/CQL1) trying out the files/software. All 3 tries worked fine. I will say for me, Kingoroot worked and kingroot did not. YMMV

Thx for all the info and the great news! I guess I thought that the phone might have been updated to far. I will give it a shot. Thanks again.

Hello, I just bought a N910V with same build number as yours. Did you have a chance to see if it can be rooted? (it seems all the instructions say cannot, just want to confirm. Thanks)

Yes I was able to follow the links and downgrade and unlock the bootloader and root and install a custom rom.

How to Reinstall stock Begonia Miui

So Installed a custom ROM here but I don't like that some things arent just working properly (camera, call sound, Bluetooth connections...)
So is it possible to install the stock Miui, that is to revert to the stock OS and the get the updates from Miui?
Im sure people have posted this before but I cant find it or any guide for it.
Thank you in advance.

Glad I could help. What custom rom did you tried out? And what version of it?
Latest Pixel Experience, I like that it has no bloatware but it just has a lot of bugs.
If anyone has a problem where you cant use McDonald's app cuz of security issues, when flashing you need to lock the device.
