[HELP] Stuck on lg boot screen - G Pad 8.3 Q&A, Help & Troubleshooting

Hello, I have an LG V495 (AT&T) and have rooted it by rooting it with kingroot, then using a script I got from here to remove kingroot and install supersu. The problem was that I had already installed supersu without updating binary and somehow the script got stuck so I restarted the tablet and now it gets stuck on the LG boot screen. If anybody can help, anybody with a rooted V495, and make a backup of all/any partitions needed to flash it back to stock using adb. I have searched all over the internet and there's no tot nor kdz file for this tablet. I have also stumbled on threads of people asking for the same thing but no one answers and also sent msgs to certain members that have claimed to help others by making backups but eventually get sent by private message, but no luck so far. Can anybody please help make a backup of all partitions via adb to see if maybe I can save my tablet? Thanks in advance

So you are at full stock, and trying to restore a nandroid backup and it's not working (sorry your post is a bit unclear).
You have rooted (I am assuming) and have the latest version of TWRP on board (downloaded through GOOManager). What is happening when you run restore from the TWRP menu?

[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.

[Q] Sprint LG G2 LS980 - no data, no signal, PLEASE help

Here is my OG post...please, anyone, help me to know what YOU would do in this case. I'm freaking out that I have a $500 paperweight I can't take back to Sprint because I'm rooted and on a custom ROM. AHHHHHHHHHHHHHHHH

Please help me, anyone. I am freaking. I flashed this ROM per the instructions (no I did not do a backup, my fault). However, although the ROM loaded, it told me I needed a T-Mobile SIM for WiFi calling to work. That may have been discussed before. That is irrelevant.
Since flashing this rom (Yes, I did the ROM, Modem, Reboot, and Firmware as said)...I can only make "Emergency Calls," I can't connect to data, can't connect to Sprint cell signal, and for the first time I can't get LG Flash Tool to work to get me back to Stock.
Can someone, anyone please tell me what to do? I need my phone soon because I'm leaving, but nothing works!!!!

Hi if you have LS980 you need to download room for LS980 here is the link: http://forum.xda-developers.com/show....php?t=2754167
Than you need to boot into recovery twrp and than you need USB OTG Cable here is the link on ebay: http://www.ebay.com/itm/13cm-Micro-U...item35d4da865d
Copy LS980 room zip file to to flash drive connect to your phone thru recovery mount usb otg than flash ls980 zip
You will be back on Sprint and after that LG Flash tool will work to if you needed

Thanks again for your instructions and help. I got the OTG, followed your steps precisely, and it SAID it installed Stock ZVC successfully (twice, actually)...yet it still will only boot back into TWRP. In download mode, LG Flash tool still doesn't work. This computer has all drivers, Windows 7, and had no issues before this ROM.
Do you have any other ideas? Now I've bought a cable for no reason. Help, please!
__________________________________________________
EDIT: I used these instructions to get me out of the TWRP Bootloop:
http://forum.xda-developers.com/show....php?t=2451696
Now I have the Stock Rooted ZVC Odex ROM installed, but STILL, no data, no signal connectivity. I try to update PRL and it says authentication error. I try to make a phone call and it says "Emergency Calls Only." This stuff ONLY happened after this (TMobile ROM). Please help me if you can. I've made major progress with your OTG instructions and getting out of the OTA TWRP Bootloop. Now how do I get past the "authentication" error and get the data and signal restored? Can Sprint do that from their side?
Edit # 2: I called Sprint, they walked me through fixing the MDN and MSID, factory reset, nothing works. It still shows "NO SERVICE," "AUTHENTICATION ERROR," AND ALTHOUGH IN MDN AND MSD my # is correct, in SETTINGS it shows my old (pre-port) phone number.
He told me to take it to a Sprint Store but clearly I can't because I'm rooted and on a debloated ROM. Please, any advice is so much appreciated.
Thank you,
BIlly

This SOUNDS like the answer...but I'm missing an EFS backup and these 2 files. Can I get my hands on these two files?
modemst1.img and modemst2.img????
Thank you... http://www.shiftpda.com/archive/index.php/t-12042.html
I've had this problem. I do think this phone can be wonky when using custom ROMs. Some people have no problem, others have constant problems, and some have problems SOMETIMES. There is no right answer so far.
I would just continue flashing different ROMs until something works. This worked for me: http://forum.xda-developers.com/showthread.php?t=2775888
But unfortunately now I have the dreaded touch dead-spot.

Yes, they did (hence the reference to LG Flash Tools). It sounds likeyour EFS partition got wiped. If you didn't back up your EFS, I think you're kinda SOL. From what I've read it's nearly impossible to get back your EFS data if you don't have the files. If you can find a way to hack it out by using someone else's files, let me know. I have mine from every backup I've done and if I can remove my info from them I'll post them. Sorry to hear about your issue, hope you find a solution.

I think I have great news. I looked in my ioroot folder and found both of the files (3 MB each) that are modemst1.img and modemst2.img.
I created a folder on the Internal called EFS_Backup, and I copied and pasted those two files into the new folder, renaming them efs1 and efs2. They renamed and stuck in the folder just fine, but running the ADB commands didn't work. So I used the flashable EFS zip in TWRP and it said FAILED.
I'm thinking since I have these 2 files I should be able to fix this, right???? But...the thing that's driving me nuts is that LG Flash Tool, no matter what version, will NOT work on my device anymore. Not with either of my PC's.
Does anyone have a suggestion for what to do now that I found those modem files in my ioroot folder?
I feel like this is the closest I have gotten and now I'm stuck. LG Flash Tools never worked on Windows 8. The OLDER versions worked fine with .tot files BEFORE all of this happened, in Windows 7. Now even Windows 7 won't work to use LG Flash Tools, after I created this mess.
Can anyone PLEASE help me take these 2 files and get them to fix my EFS? I really don't know what I'm doing, clearly, or I would have backed up my EFS first. Problem here is probably same everywhere...I've always done this, never bothered with Nandroid or EFS backups, but also never had the issue of only having an internal memory on an Android device. Stupid mistake.
I would greatly appreciate any help that can be offered. I have one more day and I can still take this phone back...IF I can fix it. Thank you in advance!
PS: I Have my ESN, MEID HEX, MEID DEC, IMEI, ICCID AND IMSI - ALL POPULATED WITH NUMBERS IN SETTINGS. WHAT IS "UNKNOWN" IS MY PHONE NUMBER AND MY PRL.

Full backup of one AFTV and restore on another
It's great to see that modstore was able to clone an AFTV.
I dont understand what modstore is saying here:
modstore said:
I'm not sure if anyone has tried backing up one Fire TV and restoring to another, but I just tried it, and all seems good.
Doing the restore though, changed the registered account to that of the backup. So I'm not sure if it would have been registered properly, probably not. But I changed it to the account I wanted it registered too, and all seems good now.

Changed what registered account? Does this mean that the new AFTV was setup to have the same amazon account as the backed up AFTV before the restore took place on the new AFTV?
I really want to be able to clone. It sounds like its possible, I just want to avoid the trial and error if possible. I'm sure others are interested in the procedure too.

Yes, from what he said that the registration info went over with the backup. If you want to clone machines, then this will work.
he didn't want to clone machines, so he had to put in the correct register info on the machine he put the backup on.

There might be a way to make it trigger the initial Registration page after doing a restore of a clone. I'll add it to my list and maybe come up with a special update.zip that will make it happen.
So if you have a FTV set up with xbmc etc you can make a direct copy of it into a stock FTV, thus cloning it as said above?
I've looked around and can't seem to find what to do. I've used adb before but have never ran into this issue yet seems so silly.
When I type "su" in adb shell i get this error "system/bin/sh: su: not found"
I've googled and all I can find is reinstalling the superuser on the phone... I'm trying to unlock the boot loader

You need root first. What fw are you on? If it's a rootable version, do that first and then follow the guides for updating here.
Yea figured it out. I'm on 1.3.0 this sucks. I'm trying to sell my amazon box to get a nexus player. Amazon has no idea how to run a home media center.
Thanks!

Guide from AFTVNEWS.
I got recovery to work everything was fine I could reboot from recovery back to recovery again (CWM) but after I did factory reset in CWM it gets stuck on amazon logo.
The reason I did factory reset was because of Error.7 in CWM I had that few times when flashing different roms on different phones/tablets
sometimes getting older cwm or simply factory reset would help.
So now it gets stuck on Amazon logo the keyboard trick to get back into CWM does not work anymore.
Anything else I can try before I call up amazon hoping they replace it ?
I can honestly say if you followed rbox's custom recovery install guide, used his recovery image, and made sure the md5 matched, you shouldn't have had any problems.
Out of curiosity, do you have an external hard drive plugged in?

Yea I did follow instructions correctly. And no I do not only had the usb keyboard plugged in so I could get into recovery.
Almost every device I rooted w/ custom recovery gave me Error 7 tablets phone etc.. I seem to have bad luck with that error lol.
Since I was on the very last step.. flashing rom -> getting error 7 grr

I think cwm still has some issues. It works fine for installing rbox's pre-rooted ROMs, but I can't backup my ftv. It always errors out.
Was this the first time you've gone through cwm install? Did you try installing one of his custom ROMs and then got that error? Did you verify that your recovery download went okay? Check the md5 against what's listed on the site.
I know it's a lot of questions, but I'm just trying to delve deeper to see what may have caused your error.

I did install recovery however at first when I had wrong firmware I installed via ADB SHELL then I Downgraded to unlock bootloader after I downgraded I installed recovery via adbfire I think newest version .17 however it was still the newest firmware of recovery anyway.... and yepp it was stock pre-rooted latest firmware that ends with "0" that did not require the fire tv boot menu.. but now I am thinking if I had the boot menu I could have got into recovery! so AFTVNEWS mis-lead me on this part... the bootmenu would be great on all firmwares actually.

I'm not sure about adbfire anything. I do all mine through Linux/android terminal/windows command line. The boot menu works on firmware 51.1.4.0. When it's sitting at the logo, have you tried connecting via adb, just to see if it initialized enough to poke around? (not sure if it works that way with ftv, but I'd try, regardless)

As far as I saw I could only connect via adb at least when in recovery mode.. otherwise it was a no go... anyways thanks for helping me out. I think there is no rescue in this situation by somehow fixing it. I mean just wanted to have few features like swap storage with a flash drive and have newest FW. But that's ok.

Sorry I couldn't be of more help :/ the issue you'll probably see is that unlocking the bootloader voids any warranty with amazon.. So I'm not sure what amazon may or may not do for you.

About the possible Lollipop ROM for FireTV,is there a way to get the latest qualcomm Adreno 320 drivers like [email protected] from another device for flashing in proper FTV directories since it is meant for Lollipop?
I am hoping for the fix for Dolphin to be runnable and Reicast to no longer cause reboots,as well as better performance for things like Mupen64Plus AE.

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

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.

Hi, my version of the G4 is H815P too (CLARO BR), and I want to know wich tutorials you're referring to and if you encounter a method to surpass this issue when trying to remove/debloat the phone...

@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.
Cheers!

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!

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.
