[Q] Huge Problem, Getting close though! Help!

(This was the most related section to my phone, if I'm wrong please move it and don't delete it. I really need help! lol.)
K I rooted last night, flashed CM7.2
Phone: LG Thrill 4G AT&T flashed to CyanogenMod 7.2
Before you guys tell me to use the search, I have! I've been working on this for 11 hours straight now cause I can't use my phone!
1st Problem: After flashing I had no service. (Yes I used search.) Tried adding APN manually, no luck with many different methods. All the other methods possible required file transfers, which leads me to my 2nd problem.
2nd Problem: My computer will not recognize my phone to transfer files. It will charge however. I tried uninstalling drivers and reinstalling them, etc.
BUT right now I have it open! Yes! Now I just want to know the best files and things to do right now before it won't let me transfer files again. I do not know why it is suddenly reading it so I'm counting on it not being able to after I try fixing everything.
If I flash to a new ROM will I get service back? Should I just go back to stock/unroot? I'd prefer to keep it rooted if I can get my service and everything working.
Thank you guys! I know a lot of these question have been answered and I tried finding them, I really did. But I'm so close now that I can actually transfer files and I just need help! Thank you. I appreciate it.
And by the way I can't just backup because when I flashed to CM7 my original backup got deleted, or just hidden deep away somewhere??

[Q] No IMEI - no baseband - Tried almost everything

Hi everyone.
As i read on so many posts, my SGN one night just drop the signal. The day after, still with no signal, i checked that had no IMEI and unknown baseband.
I had tried so many "solutions" for this to work and still nothing.
It came (when i bought it, second handed from ebay) with slimbeam rom installed. I did nothing weird to it, just simply drop signal and lost IMEI and baseband. I flashed 4.0.4, 4.2.2 from google developers web, i changed the radio for a DOCOMO one, but still nothing.
As my english is not too good, i attached a photo that explain how is my phone actually.
Please, any help will be much appreciatted as i got $300 spend on this Galaxy Nexus.

Why would you use a docomo radio? Is it a docomo phone? Have you tried flashing any other radios?

Check to make sure the contact pins that read the sim card are not damaged.

One of the solutions i've read says that with this radio the signal get fixed, but didn't work

My problem isn't with the sim card, it's with no IMEI and baseband at all. Thanks anyway.

I think i just killed it.
I was trying another "solution" i found on the web, and now the phone don't turn on.
I installed an APK from the market called GSII_REPAIR and after it says to reboot the phone, now it doesn't turn on.
I read that this app is for the galaxy S2 but appear on the search for my problem's fix.

First I would put it in odin dl mode and flash stock, that should get the phone to boot again. I understand your english isn't that good but can you explain what you have tried. Im basically wondering if you have tried to play with the nv_data.bin file in the /factory directory as this may be able to make the phone get some functionality back.
The reason for the the possible softbrick is cause the gsII repair was probably deleting and replacing the wrong files ... I would probably say that this is a corrupt EFS directory and would work on the techniques out there to repair that ... either that or you have the same problem I have where it is a hardware issue and there is no real fix possible .... One method that may work the best is to try and use QPST and manually input your IMEI into nv_data.bin file ... many possibilities I just don't know what you have tried

I try to turn it on ODIN mode, and recovery mode and doesn't turn on at all.
In the same post that i saw the app, say that i can do it manually by messing with those files (nv_data.bin) but at the end mentions a nv_data file that i havent saw on the factory folder. because of that i try with the app.

so if you can't get it into odin or bootloader you have either hard bricked your phone or the battery is dead ... usually you can still get it to trickle charge if you plug it in ... if the nv_data.bin file was not in the /factory partition then i would think in some way the EFS has been corrupted or you weren't using a file manager with root access since the file is a hidden file ... biggest thing now is getting it to boot which I can only think of flashing through the bootloader or odin but i don't know everything that is possible ... someone else would probably have to help you if you can't get into either of those

[q] flashed tot now no efs!!!

I have the efs info saved to my pc from a previous backup, but cant get it into the phone.. Anyone with some info on how to maybe sideload it via adb sideload in stock recovery???

This is my last ditch effort. Small back story: I somehow wiped EVERYTHING on my G2. EFS partition, ESN, data, SIM info., everything with dialer codes. All of my network information reads "unknown". I tried many methods from here on the forums to get this data back and it turns out I have lost my EFS partition- DNA for the network? I sent it to LG to get it fixed, having done a hard reset and leaving no trace of root. They sent it back without even asking and did no repairs. The note said "board bent". WTF?? How does the user bend the main board, especially when I never opened it? They voided my warranty and ripped off my IMEI/MEID sticker from the back of the phone.
Anyways, I am here with a brick. No network still. Here is what I have done:
1) .tot method to ZVC. Several more times... once to ZV7 where I lost touch capability. Luckily saved my arse with a micro->usb cable and a mouse.
2) attempted to root with ioroot25. Failed because the phone WILL NOT find recovery mode. adb, voldown+pwr then again from power off, and apps are unable to force the phone into recovery mode. I assume it is possible that my recovery mode is deleted?
3) Would have tried all of these "rewrite your efs/imei/etc" things but I can't do any without root. Can't root without recovery, can I?
4) Spent the last two weeks scouring the internet for a fix and going back to my Epic 4G temporarily.
Please help me, has anyone seen this before? Can anyone help me fix it? I am to the point where I would pay to have it fixed. Any experts out there? XDA has yet to let me down... I just need to know if I can fix it or if it is a brick so I can go searching for an old Sprint GS3.
Thanks all,
baublitz

That is strange, no recovery ?
So phone completely off, power and volume up doesn't put you into stock recovery?

Have you tried the recovery method detailed in this thread? http://forum.xda-developers.com/showthread.php?t=2582142
Assuming you can get the file system partitions outlined in this thread to appear on a Linux PC, you should be able to write the partition images here http://downloads.codefi.re/autoprime/LG/LG_G2/LS980/Stock_Firmware/zvc_partitions and recover your phone (particularly if you have an EFS backup).

I will try it out and update you. Did not try it since the 1st condition of the post said that your phone ought to be rooted, which I am not.

Rooting doesn't matter for purposes of that recovery method; the reason it is mentioned is because rooting can cause you to get into the soft-bricked situation if you happen to take an over-the-air (OTA) update while you're rooted.

Blu Advance 4.0 L A010U ROMs

Hey guys,
I really need to find at least the stock ROM for the new-ish Blu Advance 4.0L (model A010U), because the most recent OTA update unforgivingly bricked mine. Now I want to try to re-flash the stock ROM, but I am also open to custom ROMs, if there are any available. Please help me out! Thanks in advance

I am really surprised no one has replied yet, but again I am facing the same problem and I've been searching the Internet for one month now and I found absolutely nothing for this phone (specifically for version A010U).
So I am going to post a different question in the hopes that someone will read it and help us out:
I have two Blu Advance 4.0 L A010U phones, which are identical except for the color (white and green). They were manufactured a month apart one in 10/2015 and one in 9/2015.
Unfortunately after only a couple of months of light use and for no apparent reason (did not drop it, or wet it, etc) it started going through a boot loop. It will start, show the "bold like us" logo then restart again without making it to the operating system at all. Like I said I've been looking for over a month to find a ROM (stock or modded) to reflash but with no luck. Then I had an idea. Since I have the other identical phone that's working fine, is there a trick I can do using the working phone to create a ROM that I can use in my broken one. By the way, the non working phone will allow me to get into the recovery menu, but unfortunately nothing happens if I wipe the cache or even if I reset to factory defaults.
Anyone knows what's causing that "boot loop", how to fix it and where to find a ROM or even "extract" or "create" one using a working Advance 4.0 L ???
Thank you very much!

Man I wish I knew. I'm kinda a novice. I have the same phone with a similar problem... I downloaded the recent ota update and the first time it said it couldn't unzip it. I tried again and it seemed to work but when it rebooted into recovery it said there was an error... So it won't boot up, it just goes to the screen that says "no command". I'm pretty sure the there's a way to make a copy of the working ROM but since I don't use a PC for anything I've never taken the time to learn the method.

I just got ahold of a couple of these devices myself and am in the process of going through all the in's and out's of them....I'm a Samsung nerd so I haven't messed with something like these in a while but I got one (that was supposedly dead bricked per the lady friend of mine I got them from) at least able to boot into factory mode and recovery via ADB and just as I'm posting this I'm in adb shell going through the device's internal memory.....so we'll see what all I find and can pull out of this one and possibly know enough to post an intelligible reply with solutions next time
The boot looping sounds like a common problem with these and when I get to that point I'm going to get rid of the stock bootanimation.zip ASAP and try something else. I get the idea that these things aren't exactly power houses built for much so the littlest thing or small bug in their coding could lead to this kind of crap happening.
Hopefully you figure yours out before I toss these out the window! lol
Cheers y salud!

Forgot to add a couple things about your post, sorry! I beleive (and I just started digging into this phone) that the no command part is the locked bootloader these phones appear to have. I think it was a combo of holding both volume buttons down from a powered off state then pressing power button on that came up with the option for factory mode or recovery (which led to the sad 'no command' droid), i went into factory mode and theres an option for Tp Upgrade which Im assuming is F/W or something similar but I just hooked up to the PC and in that mode it's reading the internal and external memory of the phone and that's about where I'm at so far.

Wow! I'm surprised this thread is still going.
Anywho, I found a repository that is storing the default ROM for the 4.0L. The files were just added recently. I would have liked to have seen a custom Lollipop ROM made by now, but this device is far too irrelevant to get any attention, unfortunately. Just root and forget, I guess.

I can't wait to try it, thank you! And btw, were you able to get root successfully and if so, how?

Hey Deuler93 -
You have my respect for digging out that BLU ROMs link and sharing with the rest of us. I downloaded the one for my Advance and used SP flash tool to flash the phone that was stuck on a boot-loop. Of course first I had to download and install the MediaTeK drivers for USB connectivity with my PC. Everything worked flawlessly, no glitches what so ever. All these links are easily found and widely available online if anyone is interested I can share here too. I just hope that this boot-loop was due to some software glitch and not hardware failure. Everything seems to work fine for now, keepint my fingers crossed it will NOT happen again.
Well, one less headache to worry about. By the way we're not that far, if you're ever in the Chicago area, I owe you a beer or something. Thank you!

Hi guys !
Thank you very much for the Advance 4.0L Roms.
I have successfuly recovered my phone, but the IMEI got lost.
So, I need to root it in order to recover the IMEI, but I just can´t get success on any method :
Kingroot
Framaroot
Towelroot
is there another way to root it ?
Thank you very much.

I got temporary root using the kingroot apk. But it messed things up and I don't trust it anymore. None of the other mentioned methods worked for me either, maybe try the PC kingroot method

well this helps one thing

umm. . . when the no command option comes up just press the power button and the rest of options will appear. doesnt exactly solve your problem however unless you have the ZIP file to install, which is what I'm looking for.

What might happen if a ROM is used for another blu phone. ??
A similar phone as well.
Plz advise.

Damn! This thread just keeps going!
I haven't even looked here in a while, so I will bunch my commentary here. I'm also salaried now, so I bought into a OnePlus X (onyx), a more expensive cheapo device, so I do not use the 4.0L anymore.
As for rooting tools, I used the Kingroot APK successfully in the stock environment. I never tried flashing something SuperSU myself, but it could work. Is flashing a SU app possible from the fastboot interface?
And to Steve's question - it is technically possible to flash a ROM for a different device onto your own device, but is considered a bad idea due to the possibility of introducing incompatibilities and missing proprietary requirements. I feel like this would hold especially true to stock ROMs because the manufacturer probably has no interest in supporting anything more than the device that they are manufacturing for. Doing so removes many possible "compatibility" issues from even having to be considered, but I digress. In short, try to find a ROM made for your device and your device only.

Did you find the zip file for the recovery

You dont need root to recover imei all you have to do is type *#*#84666364#*#* in your dialer and you will be entered in EngineerMode then go into connectivity ,CDS information and radio information phone 1 or 2 then you will see AT+ type something eg.A then backspace and select the first thing you see. Put a space after AT+ and then put you imei code here "IMEI" between these "" You can find your imei by removing your battery it willl be there. After sending command reboot and imei is back.

links are down....check this instead
Hey guys, links here seems to be down .
Maybe this link would be useful for you all... stock firmware can be downloaded and useful help on videos is available too... Enjoy

SOLVED [HELP] LG G4 (H815P) Bricked "Authentication Fail #9"

Hello everyone
So, this is my problem here, I got my G4 last week, rooted it to debloat, followed the instructions I found here on XDA, and it was working as a charm.
The problem came when I wanted to change the (micro) SD card to another phone, I took the back cover off, took out the SD card, and a warning message about the SD card might be damaged came on screen.
So I turned off the G4, after I was ready to put back the SD, tried to power on the phone again and the error message appeared.
"Security Error, Auth Fail #9" and then it just won't boot.
Hope anyone can help me.
I was on stock Telcel Firmware, had rebooted the phone several times before with no issues so far.

Never mind, I just reflashed stock firmware found
here: http://devtester.ro/projects/lg-firmwares/
then followed this steps
Tutorial: http://devtester.ro/projects/lg-firmwares/install.php
So, after a clean flash, it booted again, as Iv'e had it for just one week, nothing was lost.
Hope this helps anyone else facing this strange problem.
By the way, if anyone know something about the possible cause for this malfunction, I woud really appreciate you sharing info.
Cheers!

i Have had the same problem i was woundering if you could please walk me through the steps on how you fixed yours.
I recently just bought a new LG G Stylo with MetroPCS. this is my first time being with android so i took it upon my self to root the phone and see what all i could do with it. Everything worked fine for a couple of days then i tried to reset my phone and when it tried to come back on the lg logo cane up and it said Authentication fail #9. I try to factory reset the phone but it goes back to the same screen. I can not put the phone in download mode and my computer does not detect that there is a phone there. If there is anyone who can help me please it will be greatly appreciated.

How can be LG G4 H815P be rooted, have read many tutorials, but no one is for the variant "P" (Telcel).
Thanks!!!

Hello!
Well, I found out the source of the problem on "error 9".
As it happened again a couple days after posting the thread.
In my case, when I uninstalled LG apps, such as music and video apks, "error 9" would come up on next boot.
Follow the tutorials, the most important thing is to have the right version of SW to your phone.
Also, I had to download LG bridge, then a pop-up came telling that drivers for the phone should be updated, I just accepted the update and then my phone was detected on my PC .
If you encounter a problem, please provide me a little more info (with caps if possible).
Hope to help you.

@joyousfrank. I've just been de-bloating my phone and managed to get a Security Error problem and was hoping to use this method to get the thing live again. Trouble is that Google is blocking the LGFlashtool download link. Any chance you have another link or could maybe upload a copy of the tool somewhere? Cheers

I used this thread as a guide
http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
(Follow the steps for International H815 10c Version)
This is the rooted image I used http://forum.xda-developers.com/g4/...on-root-lg-t3164765/post62251256#post62251256
After you download it just unzip it, and rename the .img file to "system.rooted.H81510c-EU"
The file must be system.rooted.H81510c-EU.img
Hope to help.

Hello!
The first thing to do, is to find the right SW foy your phone model (and carrier) as I read some problems when flashing other different than stock.
Look up here http://devtester.ro/projects/lg-firmwares/download.php there's where I found the SW for Telcel. Just input your IMEI on that page and it will give you a download link.
Then, follow this steps http://devtester.ro/projects/lg-firmwares/install.php
It's important to tell you that my phone wasn't detected by my PC until I downloaded LG Bridge as it comes with the latest drivers, so I recommend you to do this if you face the "not-detecting phone PC".
And for last, I suppose that there should be thread with a list of safe to uninstall apps (this is my first LG so not totally sure).
As there's enough room for apps on the phone, I just ended freezing annoying apps with Link2SD to avoid having the "Authentcation Error #9" problem.
Hope to help you, cheers!
