LG G4S / Beat / H735, can't find the ROM anywhere. - G4 Q&A, Help & Troubleshooting

Hello all.
I've recently bought this LG-H735 and it runs Marshmallow. Only now I've discovered the issues with its internal memory so I'd like to root in order to use my SD card as default space to install apps.
Problem is, after a bit of search I used Kingroot and it seem to do the trick... until I restarted the phone and it soft-bricked into the usual bootloop. Can access the download mode but it gets stuck at 0% for hours.
Next step would be to flash but I've been searching everywhere on the web and I can't find the ROM. All links are either down, lost or just plain broken. I'd need the PRT version if I'm geting this right, thats what my phone box shows at least.
I was wondering if anyone could point me in the right way.
Any tips would be apreciated, still new to all this. Thanks in advance.

Also... a little question update if I may. Anyone recomend a nice custom ROM for this phone? Unfortunatly Cyanogen is not compatible it seems.
Thanks again.

TCL P600 / Alcatel One Touch Snap 7025D Root and GAPPS

Root and GAPPS instruction for TCL P600
Since TCL P600, TCL P606 and Alcatel One Touch Snap 7025D are the same phones I just write about TCL P600 now. But it's working for both.
TCL P600 root package: http://www.4shared.com/zip/3HRtqraE/TCL_P600_Root.html
HowTo Root TCL P600:
- Extract the file
- Start the flash tool in extracted folder
- Make sure under options it is choosen “with battery”
- In FlashTool load scatter file contained in folder
- Click checkboxes of BOOTIMG and RECOVERY
- Doubleclick on BOOTIMG and refer to TCL-P600_130417__boot_patched_130508-162244.img
- Doubleclick on RECOVERY and refer to TCL-P600_130417__recovery_130508-162244.img

- Click “download” in flash tool
- Plug in usb in phone
- If you get a green circle from flash tool saying OK you’re ready with root shell
- Unplug phone and reboot into CWM
- Start Droidtools and plugin usb to phone again

Here is the JB gapps zip for flashing with CWM: http://goo.im/gapps/gapps-jb-20121011-signed.zip
Full instruction of getting a well working TCL P600:
1. First of all I updated the phone with TCL updater to the latest firmware.
2. I rooted it as I described before.
3. I deleted lots of China Apps and also under system/media bootup sounds and some - for me - other stuff not needed in order to get more space on system partition.
4. I installed GAPPS through CWM. I did it with this one: http://goo.im/gapps/gapps-jb-20121011-signed.zip
After rebooting I got crash of google search. I ignored it and added my google account. After opening playstore then I got update for google search. After updating there is no crashing anymore.
All other gapps are working quite well. I tested GPS for the TCL P600 and was really suprised it works quite fast and accurate.
The only thing: There is no A-GPS setting. Let's say: There is no GPS setting at all. You can only switch GPS on and off. Settings are not included. Maybe this will be unlocked with a modded rom.
I'm now testing all functions in detail but up to now it works really great.
Hope you got it also up to this point. After all steps this phone is really perfect.
------------------
If you brick your phone you have a brick Not my fault. I don't take responsibility of that my instruction will work for you. It worked for me. So now it's up to you.

Custom Recovery
Hey i want to know if this recovery can be ported to my phone the alcatel one touch fierce it is the same as th one touch snap/7025d just without the 8mp camera and splash water proofing everything else is the same i had tried the aoutomatic port for CRR recovery but when it flashed the recovery i got a security error on my alcatel that says "error 101 unaouthorized software installed "it would not boot upand was bricked i bought the same phone again and i am wondering how y'all ported it to the fierces sister phone the one touch snap .thanks and have a great day
I don't know about porting possibility. I guess there is no way. This thread is not about changing the ROM but just how to root the TCL. There is no custom ROM out actually. So I don't see chances to port. Why should this be necessary? Is the stock ROM having problems?

Solved the problems
Solved the problems.
I was able to upgrade wiht "TCL 2.7.4 Updater Setup.exe" the mobile software, I had the "TCL 2.7.9 Updater Setup.exe" version and this version told me it was updated. When I tested with 2.7.4 has recharged my sw and have gone back to the top, I rooted again with wiemerd instructions and now everything has worked correctly.
Thank you for your instructions and weimerd Sixpenny by spend "TCL S 2.7.4 Updater Setup.exe" saved me.

Thank you, i will try. I must install some other version of OS, official is fully bugged. After i used ROMs from xda for last 2 years, on my old phone, i forgot how bugged is official android.
There are so much crashes with official version, corupted SD card and so on...
please help me. after reflashing of my rom with flash tool. i have lost my imei and i have not done backup of my efs. my alcatel ot 7025d can't recognize any sim. i need efs backup or way to solve of my problem. i live in ivory coast there are not alcatel sav in this country.
I used kingo for root. Its really one click root tool. If your phone is rooted, you can restore to default. You can try to restore it with that tool.
Anyone know where to download Custom Boot Loader and Newer version of OS?
I have huge problem with this phone. There is all the time problem with memory card. I am using kingston class 10, 16gb memory but from time to time, after i take some picture or use default gallery, i get message that my memory card is corrupted. I need to restart phone and everything is ok, but sometimes it require even 3-5-7 restarts and its really anoying. Cant take pictures, use ringtone from memory cartd etc.
I tried with official updater but still use 4.2.1 version. Anyone have any newer custom rom?
Sorry for off topic but i am sure that this problems can be solved with some newer OS.

[Q] Help save my phone please!

I've been looking around this website and trying to fix my soft bricked at&t galaxy sgh i747(failed root) but there are multiple methods and it's extremely confusing. I've even lost all my data from a factory reset. I've tried to follow these instructions the most because no sd card is required (which I don't have) and it's the simplest:
http://forum.xda-developers.com/showthread.php?t=2658486
I downloaded the second cwm link but I can't seem to get it into into odin because none of the extensions are being recognized. I've been trying different methods for about 3 days now and nothing has worked. It took me hours just to get odin to recognize my sIII. Is this even the correct method to follow?
I just wanted to debloat all the crap those corporate parasites forced onto my device but it's not worth the headache. Please point me to the correct thread or whatever so this torture can end and i can be on my way. thank you so much.
BACKGROUND:
I don't have an SD CARD and the android version was 4.4.2 before the brick. i tried using kingo root which rooted the verizon version on my at&t phone and then I uninstalled some bloatware with an app and when I closed the app, the top bar started to flicker and then it closed. I have not found any posts with my situation and I'm beginning to think I'm SOL. Posts have told me that my phone cannot be downgraded because you can't use a lower android version and other posts say you need an SD card. I'm able to get to the download mode and factory reset page.
The phone even boots onto the home screen for the wizard guide, but when it gets to google services it says the wizard has stopped. I'm able to mess around with a few things like the settings/camera but there are no apps.
Will someone tell me if there is any hope. There are so many tutorials out there, but I have yet to find a clear one for my situation.

Properly the reason you bricked it was that you flashed something from this forum which is the international i9300 and any file here will not agree with your phone. You need to report your post and get it moved to the at&t forum where they might be able to help you.

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.

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.
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.

IIIIII'm stuck!

Long story short - Bought an LG D851 off Swappe. It came with CM13. I've been sticking nightlies on it. Currently on 2/14. I tried to put 2/18 and found that TWRP wasn't working - it hangs on TWRP Splace. Then I noticed SuperSU wasn't on the phone. So I installed it. Can't update the binaries. Looks like I don't have root.
Used LG Flash tool and flashed D85120E_00.kdz. Part way through, I get an error that the software cannot communicate with the server and it asks if I want to abort. I let it continue.
The phone reboots, I get the "Android is updating 1/196", etc. After which, it reboots, I get the boot jingle, and then it holds on the T-Mobile screen. I've tried flashing the KDZ a few times with the same result.
So now, I humbly, yet again, ask for help.
The endgoal here, is to have a working ROM with BT and WiFi working. I really don't care what it is at this point. Marshmallow is nice. Lollipop is okay. Whatever. I just need a working phone.
Thanks in advance, as always.

Ouch!!! Read my CM13 post...you don't need SuperSU anymore (CM13 has root built in)--I had the same problem a while back--fixed it by flashing the old factory version on the phone & then used Purple Drake to root it & then installed CM13...Was a HARD lesson for me.
Upshot---No SuperSU needed--No BusyBox needed on CM13. If you are used to the old way of doing things--you'll get B0rked big time.
Luck to you!!!!

I guess trying to push the SuperSU binaries is what effed up TWRP?
I'll check out your CM13 post. But the issue I have is that I can't flash a factory version with LG Flash Utility. I mean, it does, but now it just sits on the Tmobile splash.
Hopefully your post will show me something I missing.
@debianmain1 is this the post you're talking about? http://forum.xda-developers.com/showpost.php?p=65432245&postcount=158
I tried that DD command to no avail last night. I tried everything I could find before reaching out to everyone for help.

Yes--the SuperSU binaries B0rked my install real good ( as I understand it--2 different types of SU installed B0rks everything )..... And with CM13, you have to allow ADB & apps to have root. I've been modding phones for years now & CM13 threw me under the bus until I learned what to do... I use to ALWAYS root, install BusyBox & SuperSU---not with CM13
Ya--that won't help you I'd look up fastboot commands & try to flash it that way--sounds like you are stuck in a startup bootloop. I did see some info online about starting the G3 in fastboot--I had a very hard time getting my G3 fixed. Do you have a Linux computer to use? It's easier to work with some of the diag stuff with Linux.

I can always fire up an Ubuntu flash drive if necessary. I'll get working on Fastboot.
Thanks again!
@debianmain1 Hmmm, Fastboot doesn't seem to be functional. I've got download mode. Can I push something to it that way?
I managed to get somewhere yesterday. I tried flashing D85120e_00.kdz and it failed again. I got the "cannot communicate with server" error, then it rebooted and tried running initial setup and failed.
So I tried flashing D85110C_00.kdz. Much to my surprise, it worked! So I ran through initial setup and got the phone working to make sure all was well. I rebooted and got the Red 2. So now here I am. Guides show that I should be able to put it in download mode and reload factory firmware again. But all I get is the "Download Mode" graphic. It never switches over to the updating mode with the circular arrows. I fear the worst at this point, but I really don't know enough about the LGs to diagnose my own doom just yet.
Someone on Reddit pointed me in the direction of Board Diag. Unfortunately it doesn't appear to work on D851. Running out of options. Looks like it'll end up being an expensive learning experience.
