[SIZE=+1]Q6: How can I Sim-Unlock my phone ?[/SIZE]

Call T-Mobile and request to unlock the Sim-Card using device unlock app that came pre-installed from T-Mobile. Get your IMEI number ready. You need to wait 40 days to be T-mobile user if the phone financed or lease, but you can unlock it right away if you purchased the phone out right without contract. I did it and use it on ATT network with no problem. Thanks to my buddy @markbencze that confirmed it in HERE and @Warrior1975 that also confirmed it in HERE​

[SIZE=+1]Q8: Am I required to backup my ROM before flashing anything else?[/SIZE]

No you're not, but it is definitely a good idea and always recommended because if you don't do a backup and then something goes wrong, it means that you'll lose all your apps, data etc. It just saves a lot of hassle.​

[SIZE=+1]Q9: How to get a logcat if I'm asked for it?[/SIZE]

Here is a link for learning how to make a Logcat[UNIVERSAL][LOGCAT]How to get & read a logcat/ Troubleshoot your own issues!
​

[SIZE=+1]Q10: What does MD5 checksum mean??[/SIZE]

MD5 digests have been widely used in the software world to provide some assurance that a transferred file has arrived intact. For example, file servers often provide a pre-computed MD5 (known as Md5sum) checksum for the files, so that a user can compare the checksum of the downloaded file to it. So this tool are to make sure that you would get same file as the developer uploaded file. Download MD5 TOOL CHECKER​

[SIZE=+1]Q11: What is the best ROM/kernel/modem??[/SIZE]

Honestly, there is no "best". It's all based on personal choice. For example; I may like heavily customizing my ROMs where as you may like it to look at stock as possible. The best thing you can do is to just test out different ROMs/kernels/modems and see which you prefer.​

[SIZE=+1]Q12: How do I restore a Nandroid Backup?[/SIZE]

Enter TWRP recovery mode again and look for the ‘backup and restore’. Select restore and everything should go back to normal in a few minutes.If you choose the ‘Advanced Restore’ option, you can select which component of the backup to restore – like the boot, system, data or cache .... Reboot to system. Your system is now restored and is exactly same as the time when the backup was made.​

I've noticed that Google Now opens kind of slowly on this phone. You may start typing in the search bar, then it will reload and the keyboard will disappear, then you'll have to tap twice to get it back. Finally then you can type and search. I'm just wondering if this is the app or is it only on this phone that it does that..

I haven't flashed a ROM, just rooted the odexed stock ROM.

Been having some bluetooth issues lately. A device will pair then suddenly music will stop playing through bluetooth and play through speakers instead usually after a few minutes, even though the device and phone are still paired. I have seen this occur with multiple bluetooth devices and across 3 different roms. Any ideas?

I've tried stock, EYG Kernel, and the mods by warbeard_Actual. Same issues with all. Usually the issue shows up after a few weeks of usage in each rom, so I doubt it's hardware failure.

Edit: I've figured out the case. When my data connection drops, my bluetooth seems to flip out too. Which brings me to another issue. I've been having data drops close to every 30 minutes now, sometimes more than that. My family who is also on tmobile are not having these issues, so it's no issue with the towers. Not sure what's causing my data drops.

Do you have a source for me for MMS.apk? Also, btw, I'm on Tmobile LG V10.

Have not experienced this issue or seen any other posts about it. Are other people getting double texts from you or just her? Have you tried another messaging app to test and see if that also replicates this issue? I always tell people to use Textra for messaging. Maybe try that or any of the other countless text apps.

Hello to all,
Respected members I have a LG v10 T-Mobile version with MM 6.0 stock version. I bought the phone today only. I have rooted many phones without any issues or trouble. Today when I used the method described in this thread [ http://forum.xda-developers.com/tmobile-lg-v10/development/tool-t3283944 ]. Now the problem is that I followed all the instructions up to the letter & everything was going ok.
I clicked the install.bat file the phone rebooted in download mode then it displayed that welcome to fastboot & there were a few options. On pc it in the CMD window which opened when I clicked install.bat file
which was present in the zip file I downloaded from the post it was displaying that waiting for device for I think may be 2 or 3 minutes. The it closed after 5minutes & I was seeing a black screen with 2 options with fast boot heading on top. The first option is to press the power button for 10 seconds to restart the phone or press fast reboot from adb. The problem is that I clicked both up & down volume keys after keeping the power key pressed for 10 seconds or more but nothing happened. The screen stayed for atleast 40 mimutes. Now the problem is that When I took the battery out of the phone to restart it booted & then after
lg mobile logo it displays that software not Recognize or Recognition failed. Can anyone please tell me what to do or that it is bricked or not. At the moment there is no bootloop or anything else. The phone is still connected to the pc with usb cable & is in firmware update mode. One more thing I wanted to respected members is that can I remove the phone or not. The phone is connected since 3 hours. I am at the moment download original stock firmware for T-Mobile v10 which MM 6.0. Any help or suggestion is greatly appreciated.


The phone booted to main screen & everything works fine. I also did a hard factory reset. It starts now but the only thing is that it displays that Phone software cannot be checked for corruption. It displays this for atleast 7 seconds & then the boots normally. What should I do. Should I flash the stock tmobile MM6.0 again through LG flash tool. PLease any suggestions r greatly appreciated.

Looks like the thread you used was for lollipop rather than Marshmallow? Sounds like you got it booting up now tho, so if you wanna root, jjst make sure to use a guide for rooting Marshmallow 6.0 [emoji106]

I've got a fun one.

I'm not sure what happened exactly, but after failing to install a kernel for 6.0 MM for my V10, I've lost a bunch... But still have a perfectly working phone?
fast charge, Fastboot, ADB... LG Up and LG Bridge don't recognize my phone anymore, and Windows 10 reports it as "Unknown USB Device (Device Descriptor Request Failed)" in the Device Manager.

I've tried multiple PCs, multiple cables, tried it on my Raspberry Pi and MacBook Pro too... No dice.

I still have TWRP working, I've still got my root going, and I do have xposed framework installed...

The heck did I do that I can't seem to undo?! Help!

 

[linsalata28]

Can someone please help me? I just got a T-Mobile LG V10 off eBay. It said the phone would just reboot and apps were crashing. His wife was due for a upgrade so she just got a SGS7. Will I got there's phone working I unlocked the bootloader but am still having some trouble flashing TWRP. But my real problem is that the phone has no sound and the mic isn't working. Everything else works great. Even vibration.
Any help would be much appreciated!
Thank you!

Any Way Out of Brick?

Hello guys I really need your help please. My LG v10 h901 bricked and it was on Tizen v5 custom rom, prior to that it never gave a problem - not even once.

I just received a call with my phone while driving and after a while? I realize no activity. I check & see that it is stuck on the "your device software can't be checked for corruption"

If I remove the battery, put it back & connect the charger, it charges & shows charge progress.

I can get into the factory reset using hardware keys but I can't get to TWRP.

I removed the sdcard and everything seems to be intact without corruption.

There was this one time it got in for some few minutes then restarted to verification stage.

I can get into download mode but in the device manager I see LGE AndroidNet USB Serial Port, It also shows up as LGE AndroidNet USB Modem. I've tried many things including flashtool, lgup and uppercut to no avail.

It doesn't overheat.

Bootloop or just maybe os/recovery failure??


I've tried everything here and on several websites to no avail. I thought of any modification I made to the phone prior to the problem & realize the evening before the bootloop, I installed "Swipe" & "All in One Gestures" to get full immersive look.
On the swipe, there was a time I got a warning & cos I was driving I believe I selected Ok.

Today, I was doing the same setup on my G3 then the warning came up and I read it carefully & selected cancel. I have a feeling that's my problem (it isn't the expected LG bootloop).

It is still stuck on the verification stage . When I checked on flashtool, I realized is no IMEI.

Tried to use fastboot to flash recovery.img boot.img aboot.img and laf.img I got from the tot I flashed TWRP with but it isn't seeing the phone.

Thanks Guys!!!
NB:

Got fastboot to work, see device and reboot command works but all other commands to erase or write images (boot & recovery) had error FAILED(recovery: unknown command)
