But I was already on MM when I followed this guide, and it worked. I can swear I had MM when I bought the phone.

If I can find a stock Lollipop image, can I then flash it and follow the instructions in this thread again?

Does anyone know where I can find an LP firmware file for the H901 (Tmobile)?

Thanks!
There's no going back. It will brick your device.

If you are on official MM you cannot go back to LP

Disaster averted!

OK, so I wasn't willing to wait on TWRP/root for MM. So I retired my phone to the T-Mobile store and traded it in for another H901 v10, via the JUMP plan. I lied and said the phone auto-upgraded to MM and was freezing up. My replacement has 5.1.1 LL. I'm about to install TWRP and Supersu again.

I just figured I would put this out there as an option for v10 T-Mo customers. I can't guarantee they'll let you do an in-store trade-in though. And there was a down payment of around $280.

I've learned my lesson, avoid MM at all costs if you value customization and hackability.

@ shadowcreeper_1: It depends. Did you buy the device *from* ATT, or TMO. If ATT, then no, because the boot loader is supposedly perma-locked, which means no custom recoveries, ever. You may have been able to root, but that's about as much you can hope to accomplish within a reasonable time frame.

If you bought from T-Mo, it should work as long as you never took the MM OTA update (or manually flashed it). My method of returning the phone to the store for exchange might work (to get a same device running Lollipop) if you had the same predicament as me. But you have to hurry because soon the devices T-Mo sells in store will have MM update already factory-installed.

Another approach is to buy a phone you want from T-Mo, unlock the SIM card, cancel the contract, then go buy service from ATT. This will enable you to have service from ATT while still having having the T-Mo version of the device that is fully hackable with custom recoveries/ROMs. Downside is you'll take a credit hit if you cancel the contract while the device still isn't paid off, and you risk the device's ESN being blacklisted after switching to ATT, which means no cell company in the US can sell you service for the phone, essentially leaving you with a wifi-only device. So it's better to just buy the phone outright off-contract/prepaid, paying the full price upfront, then get the SIM unlocked and switch.

Alright then. Well, seeing as the last page has been taken over by illegible postings that have no bearing on TMO devices... How about we get things back on course??

Is anyone working on an update to v3.0.1-0?

***EDIT***

I didn't think so... I have created a new post for continuing work on this project:

I've searched through the thread and can't find my issue so I'll ask, if it's been answered my apologies for duplication.
I have many backups on my SD card and when I go into twrp the restores section is empty, I have booted into the phone and can clearly see them in
the TWRP folder on my sd card and can also remove the sdcard and mount it in my reader on my pc and see the files all there.

Quick backstory, my V10 died and so I bought a new one, flashed TWRP fine and loaded my rom fine, no issues.
Launched back into TWRP to load my last backup and the Restore option has no entries to restore.

***Resolved***
I discovered the TWRP backups are in a folder with the device ID on it which changed on the new phone.
I made a new backup and it put it in a different folder so I have moved my old backups to the new folder.

Of course you'll get an error. Fastboot commands were removed after MM. You need to root a different way.
So depending on what Firmware you're on will determine which way you'll need to root.

OEM Unlock unlocks your SIM card, not the bootloader. I have no idea how to unlock the latter. :(

SIM cards can only be unlocked from the device unlock app. OEM unlock if for unlocking the ability to run the fastboot command 'fastboot OEM unlock' which in turn unlocks the bootloader.


@have0 reboot and try again. Enabling the OEM unlock option worked the first time for me on my last 3 different LG devices, so unfortunately the only other idea I have is that if your bootloader is truly still locked then turn off developer options and then turn them back on, then try the OEM unlock switch again. Also this recovery version is depreciated and has the efs backup bug from its twrp source. I suggest this version as it is the closest to having the correct time/date when you perform backups.

Can someone please help me? I have the bootloader unlocked. When I try running the command in the OP to flash the recovery it says "I'm not looking at it now so it's not exactly what it said"
It says it's flashing the recovery finished then something else.. Can't remember but the last part says error flashing recovery.img command not found.
I'll go on later and get the exact error.
What I really wanted to know was where am I to put the recovery.img ? I put it in the same folder where I have adb and fastboot and then I tried putting it on the root of the internal memory on the phone.
Thanked for any replies.
