It also doesn't see the firmware version and bandwidth

Never heard of any such issue. Try flashing kdz.

After installing software using LGUP, the phone keeps resetting itself

It works!!! For those in need: I turned on LGUP and selected the "ChipErase" option

But now you have wiped your IMEI and serial number. In all my guides I warn people not to use that option.

Right. I haven't checked it out. There is no IMEI or SN now. Can it be restored somehow?

Such things are not allowed to be discussed here on XDA, as far as I have heard. You'll have to find another site to see if there's a way to do that.
In the future, don't go running around without knowing what you're doing, because you will break things, as you have just now done. Most people should never use Chip Erase, as detailed on many threads here.

Success with adding IMEI. Now there is still SN

Yeah this sounds a lot worse than playing with Windows Regedit.
Cloned hdd copies are a beautiful thing...

Have you CID unlocked your device?
100%. I've flashed a few times.
Try flashing the new nosize USPL.

I can try that. Could you pls give a link of that? Thx.
Here. Also, have you switched from XP to Vista by any chance?
I didn't change from XP to Vista. I'm doing this on XP. But still with no luck. I couldn't flash the RUU_Signed.nbh either and had exactly the same error. After a reset, it just stops at the white screen somehow. damn...
Actually the update utility i used before to flash my mobile may be different from the one i'm currently using now. so i'll try using the same update utility later and post the result. im thinking maybe it's the update utility reason.
Ok. It works now. I removed the sd card and it just works. I know this sounds stupid. But before I 100% had the experience of successfully flashing it without removing sd card in advance.
And finally I kind of have some conclusion. If the sd card is in, the flash process would search for the sd card which is a quite time-consuming process lasting 3-5 minutes somehow on my device. And this causes the flash fail because it may have a timeout value less than that. If the sd card is removed, the search sd card process will end immediately and the device goes to next step very soon.
Just hope i've made this clear and can help some careless guys like me.
And thanks for randythered's kind heart.
No problem, and I feel sucky because I knew this is one of the possibilities and I forgot about it AGAIN! Somebody else had the same problem a few weeks back and I gave him every solution except removing the sim card and SD card. Jeez...!

[Q] issue with verizon lg g3 custom roms

Hi xda ! I'm hoping someone can help me ! I have a Verizon LG g3 I was messing with custom rooms and I flashed cm11 I believe and decided I didn't like,it ( I know weird) but I flashed back the the Rom I liked prior and realized my phone didn't recognize the SIM anymore. So I tried different rooms and have come to the conclusion it won't read Sims anymore. I want to uproot and go to complete stock, I have tried the different ways online and I can't find how to change port settings. If someone could assist me in either flashing back or any ideas on why it won't recognize Sims because I want to fix it that would be great! Please email me at [email protected] as I don't get on here to check often thanks

Have you tried turning off your phone > pulling your battery out > pull out your SD card and SIM > Clean them up nicely, blow a few times in the SIM/SD card hole on your phone > re-insert > Boot up your phone.
Also, this should be in the Q&A section. You've been a member on here for over a year but only have two posts, so I guess you don't frequent the forums very often. Please use the exclamation mark to report your thread so the mods can move the thread.

D855 version and 4.4.2 rooted
v10e,f,g,etc? first, try reinstalling dual window. apk with titanium backup, and if that doesn't work, and if it means that much, try upgrading software. you'll be able to stay on KK. otherwise, may as well go to LP. it works well and there is one click root + twrp

v10g eur, thanks I will try that! I really don't want to go lollipop I've only heard complaints about it, killing batteries etc
quite the opposite for me; I had a 9000 mah zero lemon battery on my g3 in KK days, now on LP I use the normal battery because battery life is good enough. create a nandroid, move it to your external sd card, clean upgrade to LP with LG flash tool 2014. if you don't like it, just restore to the backup and it's like nothing changed
up.
anyone encountered this?
OP, report back what you have tried

[HELP][NOOB] SM-N900T can't register on the network

Ok, forgive me ahead of time for anything I've overlooked, but I need a point in the right direction at the very least. I have rooted and flashed multiple ROMs to my N900t , applied countless tweaks, and tested 100s of Xposed modules. The device used to work on the t-mobile network, but I switched to a N910a to use as my main device. During that time I continued to flash, wipe, and repeat trying to learn how android works. I lost the note 4, and when I went to put my new Sim into the note 3, I could not register on the mobile network. I full wiped, went back to full stock nk3, Uninstalled Xposed framework, tried to figure out what the problem is, but I am stuck and have no idea which way to go. I want to get my device working on the network ASAP but at this point, I'm stumped as to what the problem is, let alone the solution. I'm guessing the solution lies in the hidden service menus, but I really don't want to mess things up anymore. I have no problem donating what I can for the help and time. I really want to learn android programming and development, and more than anything I'd like to be able to use the service and device that I have paid for. I've attached screenshots, and I can provide more information to anyone willing to help. Thanks to anyone and everyone who takes the time help.
Device info: SM-N900t, Knox warranty void: 0x1, CSC: TMB ENK3, bootloader pda and baseband: N900TUVUENK3, kernel: 3.4.0- 2587359, rooted, supersu and busy box installed.

Dialer Codes Not Working

Hello everyone,
I have a Samsung Galaxy S20 Ultra (SM-G988U) from Verizon Wireless. I am not from the US, I got the phone from a guy who bought in the US.
I am currently in Romania using Vodafone SIM card (Idk if this is relevant but thought I should give as much info as possible).
The thing is, no dialer code works, *#06# for IMEI code, *#0*#, *#*#88#*#* and all the other ones. It either says invalid code or something like that or "UNKNOWN APPLICATION".
I am running original unrooted firmware Android 11 One UI 3.0 (G988USQU1CTL4).
Is there anything I can do to solve this? And is there a way to get rid of the Verizon stuff without rooting? (like changing CSC or something I don't know I'm not all that knowledgeable regarding this stuff, I just read the stuff posted on the forums)

Not sure if it will work. But try downloading the Google Phone Dialer and see if they work in that app.
I get the same errors with the Google Phone app too.
Codes won't work if the BL is unlocked or rooted.
Happened on my old S9
At least read the whole post before replying , I am running completely original unrooted software. Didn't touch a thing on it.
Didn't mean to make it sound passive aggressive, just frustrated with the whole thing.

perhaps the previous owner rooted the phone before.. try to enter download mode to see if it was rooted before.
