Unlocking and Rooting AT&T LG V10 H900? - AT&T LG V10

Has anyone looked into the at&T variant yet? I'm having troubles getting into the bootloader and into stock recovery. I want to unlock so I can test whether anything for the h901 works with the h900 ( and eventually get on stock 6.0. This DPI is driving me nuts). I've tried all the button combos I've read and could think of, and adb reboot bootloader just reboots back into Android. I don't think AT&T is pulling what Verizon is, since I have the 'OEM unlock' option in dev options. So, there's gotta be some way to do it... Hopefully we can get this guy figured out

T get to stock recovery I used a trick we had to use for the OUYA. I send an "Alt+Sysrq+i" command with a keyboard via OTG, on boot at the LG logo. Holding "alt+sysrq" then tap "i" 5 or 6 times and it will load into recovery. I was hoping once there I could do something like "adb/fastboot reboot booloader". But couldnt get adb to see the device. I think there is some auto repair script that's running, hard to tell since there is no feedback on the screen other then the recovery icon. But after 3-4 minutes it reboots goes through the "app upgrade dialog".
For the EOM unlock option, I noticed that it never does actually check in the box after you select "enable". Maybe look at the log cat and see if we can find some app/process messing with it?
Haven't opened the thing up yet, but maybe see if we can throw some commands at it while its in recovery via UART pins with serial to usb (bus pirate)?

I have successfully booted into download mode but unfortunately ADB and Fastboot dont work. I did also manage to get into the factory reset screen with the hard buttons. I am backing up my phone right now and gonna see if maybe it'll take me to recovery instead of actually wiping the whole device. Maybe even check if ADB works on the screen I will share my findings once I've made sure it won't harm anyones device doing this.
I just realised I have a fresh install on laptop and my ADB might be the older version cause it was downloaded from synaptics manager. I'll be home later this evening and ill mess around with it. I am downloading android SDK tools for Linux right now so lets hope thats what it was.

How'd you manage to do that? I've tried a combination of buttons, but nothing.

Download mode - power off device completely, hold down volume up and plug usb in to PC.
Factory Reset - power off device, hold down volume down, hold down power and let go of power button once LG logo comes on but hold volume down, it'll reboot twice I think and then take you to factory reset screen.

Really hope you find the work around. Alot of people say at&t isnt going to allow rooting of new devices.......if theres a will theres a way!good luck

no updates?

I have this h900 but when looking for the 10f update, in the update center,it shows that im in the latest version, im in 10d and afaik there are some people with the 10f version that fixed the finger print scanner.. How to get this update?

I have the same problem with my AT&T H900. I'm on 90009e and wanted 90010f. AT&T Tech support couldn't get it to upgrade either which I find very odd. We really need some phone mastermind to unlock the secrets of the AT&T LG V10 H900. I'm unable to get it into download mode or unlock the boot loader either.
Thanks,

Hmmm that's wiered because mine has stayed checked since I got the phone,although I don't t think it matters since it isn't unlocked. What's funny is i don't know why you can check it if bootloader is locked, I'm still lost on that one .

This has been asked and answered here

How to get into stock recovery
1) Enable USB dubugging
2) Plug phone into computer
3) Set USB connection type to MTP
-Now the "USB debugging connected" notification should appear.
4) Entering "sudo adb reboot recovery" into the terminal will reboot you into the stock recovery.
Note: Entering "sudo adb reboot bootloader" will only reboot your phone...
Using: at&t LG V10
Model Number: LG-H900
Android Version: 5.1.1
Build Number: LMY47V
Computer OS: Ubuntu 15.10

I was able to root an LG escape2 with this method. You can communicate and push files to your phone through the download mode without technically using adb. Any chance a method like this would work?

help- bricked it, no recovery, what now?

Hey yall. I had the phone for 6 days before I bricked it. I am wondering if there is any stock recovery mode or anything or what I shsould do? I think something went wrong due to using the root toolbox pro app. I have done some backups within the ap as well as Titanium Backup but now the phone will not boot up and I dont know if/how to put it in factory recovery mode. Soft reset does nothing. The Motorola logo will show on startup but then the screen just blacks out forever, not off, just colored black.
A few details, the phone was rooted with Motofail2go, with no recovery and bootloader still locked as far as I know.
Should I take it to Sprint for a factory reset? Is this even an option? What are my other options?
Next time I will probably use the Moto unlock key so I can open the bootloader all legit like and have a recovery mode...
Try holding power button and the down volume key to power off. Once you power off press and hold them again. This should boot you into fastboot, Motorola's adb shell basically. This can take a couple tries, make sure the phone is powered down completely before hitting volume down and power button to get into fastboot. If you can boot into fastboot you can unlock using this guide: http://www.droid-life.com/2012/08/20/how-to-unlock-the-motorola-photon-q-bootloader/
Once unlocked flash the custom recovery of your choice (I like twrp). You can boot into custom recovery by holding volume up and the power button from a powered down state. Here is the link for instructions on how to flash twrp:
http://forum.xda-developers.com/showthread.php?t=1887070
Then you can download one of the stock backups for the Q posted in the development section and restore them using the custom recovery. Most of the ones I have seen have been compatible with twrp.
The only way to download the stock rom backups is to remove the sd card from your phone, plug your sd card into a PC or other device with a card reader, download the stock backups, and place the stock backup rom files on your sd card. Finally place the sd card with the stock backup downloads into your phone.
These backups and information on how to go through this process can be found in this thread on page 2: http://forum.xda-developers.com/showthread.php?t=2001226
The key is to make a backup of your existing rom with twrp and then move the stock backups from your sd card to the twrp/backups/yourdeiceserial/ directory. That creates a backup directory which twrp knows to look for backups in.
Don't feel bad, I've been in that state several times since getting the Q, live and learn.

If that does not work you could drop it in water or something. You have not officially unlocked boot loader so you still have warranty. Or you could just tell sprint it quit working and act completely clueless. At least its bricked with warranty still intact.

Both of the methods above are very effective. When I had the first photon I bricked it and just dropped it in water and did a claim. Depending on the insurance you have that way may cost you $100. The other method should work. When I first got this phone I did the exact same thing and to go back and unlock then flash twrp and in stall a stock backup someone had posted.

Thanks for the response. Is there anything extra extra special about getting into factory fastboot mode? I can't seem to get it done. Is there an official set of instructions anywhere? Does the phone need to be plugged into the PC? It was always my understanding (for the last week) that Power and Vol Down was the soft reset mode which reboots the phone. Therefore it always tries to reboot in normal mode. This is what keeps happening. It never powers completely down using this method.
Anyhow, once I follow your instructions, the Moto logo appears, no Sprint logo appears, the phone "powers on" but the screen is blacked out (not off). After waiting for a while at the blank/black screen, or holding down several buttons like vol or camera I get the first attachment: "Process system is not responding. Would you like to close it?" When I wait nothing happens. When I push OK nothing happens. By chance, I held down power during the notification and the power menu came up behind the ANR notice (second/third attachments). So obviously there are some things working but the main system isn't booting up. And either factory fastboot is nuked or I can't figure it out. When I power down from this accessible power menu and try to do the fastboot (Power / Vol Down) I still havent gotten it to work.
Any other ideas before I take drastic measures?
Since I bought it from Amazon would that be my best route for return or should I go thru a Sprint store?
Thanks in advance.
Hi again yall. You know once I got to thinking about it, I decided to check out the return policy on Amazon Wireless. They will accept any device under warranty for the first 30 days and it is up to Moto for the next 11 months of warranty coverage. They email me a packing label and it ships out 1 day and they ship out the new phone 1 day shipping. Hard to beat, just takes 2 days of shipping and some more fun times with my Epic, 10.1CM style, in the meantime.
Who's to say it wasnt some sort of hardware or software glitch that bricked the phone rather than my screwing around? Nobody knows and it isn't up to the consumer to prove his innocence. I bought everything legally, all the apps at the app store, and only ran the motofail2go root method. Wasn't running any custom Roms, Mods, or anything. I don't feel bad after they got me for another 2 grand for 24 months, and since I have been with Sprint for 10 years;l I have spent well over 10k or 15k with them lifetime.
If any other method pops up between now and when I ship it out I may give it a shot but if not, ah well, capitalism.

Try using adb. If your computer has drivers on it for phone you might able to get into fast boot. If that does not work I would try Sprint store first. Have locked my phone up several times while hacking wife off in progress and have used adb every time. Only time i have been truely scared is when i soft bricked my nexus 7. had to stay at work for two hours after i got off to get it to recover because i was scared of her lol.

If you get adb to recognize device you could take chance and officially unlock boot loader. Then flash twrp. There is a thread in general section about having trouble getting official update. It has a stock recovery in it. Trick would be moving files to recovery section of twrp
I have gotten the phone to soft power down and get into fast boot and custom recovery. It's a bit tricky with timing, I usually wait for the screen to go black after soft reset, let go, and immediately hold power and volume down. If you can not boot into fastboot I honestly don't know what you can do either than return the phone.

Thanks for the help Unicron. I think Brandons method might be my only alternative... but you know what? I already have the box packed up to ship back to Amazon! I am still a noob; I dunno if I could go the distance on this one. I have been updating my Android SDK files since I got the phone but I never got it to recognize boot up thru ADB fastboot. disclaimer* I havent tried it in a couple days since all teh SDK updates completed.
I dunno though I am a big time DIYer when possible. If it werent for the massive amount of tape I put on the box and packing label I would already be trying this method. I can't convince myself just yet. Amazon makes it too easy. I could have the *new* phone by Friday. Then I wouldn't be wasting my remaining work week trying to hack into my personal Christmas present in order to make it function...........................................
Edit - Yes I'm impatient. My job is too demanding and I am trying to set a good precedent for 2013. Wasting the first 3 work days on a phone is not how I intend to start off the year. There is probably a valuable lesson to be learned from this as far as hacking experience and to be honest with the responses here I think I could get it to boot up from PC in SDK/ADB mode and go from there. I just didnt know if that was possible until after I made the claim with Amazon. I still have an entire day today and tomorrow if I want to indulge myself. It doesnt matter if I mail the package today or Wednesday, I can still get it by Friday. I believe this thread is still valuable because we have patterns of repeating past failures and I may find use of it when I recieve my new phone and, darn it, it mysteriously bricks as well. in the same fashion.... the only thing I was really trying to do was get all my apps on my SD card... sad huh?
Edit 2 - Opened up the box, tried fastboot and adb, nothing. Off she goes.
I don't blame you, it sounds easier to exchange in your case any way. The main suggestion I have is if you are getting into any type of build.prop or operating system tweaks that have potential to lead to boot loops or cause the phone not to boot, then unlock the bootloader and install custom recovery.
The Moto-fail method seems limited to only be able to run apps that require root. For me this has no use as I want to be able to have complete control over all aspects of the Android OS. There is not a huge mod community for the Q as yet but I believe Cyanogen will be a reality as Interloper continues working on it. I came from an Epic with Cyanogen and soft-bricked it a minimum of 50 times. CWM was very forgiving on that phone, the Q is a lot more finicky and frustrating.
If you have insurance through the carrier then you are going to pay $150 for a refurb if something goes wrong and you hard brick the phone. If you unlock bootloader and install custom recovery then you have a fail-safe in the form of nandroid backups and restores. Then you can mod away with little fear.
Good luck on the new phone and I hope you don't give up after six days of modding with the Q!

FWIW, pressing vol down + power til it resets then pressing the camera button + power once the screen is black gets you to the Boot Mode Selection Menu, where you can start recovery, fastboot, BP tools (still not sure what that is entirely) and some others. Seems to be a fairly reliable/easy method for getting to both recovery and fastboot from any point.

It does work without any recovery mode and I believe it still works without the bootloader being unlocked, I didn't know about this myself until after I had already unlocked it. Sorry I couldn't help out sooner.

For anyone concerned, I knew it would only be a matter of time until bricking my new device. This damn Root Toolbox Pro did it to me again, and on a simple, menial task. I am going to be working thru the motions on getting this to work.
Using the instructions quoted I did get stock recovery to work or at least flash on the screen for a split second. Seems like there is a timer on the recovery screen. I am having trouble with the fastboot prompt though on the PC. Do I do it in the "platform-tools" folder which contains fastboot or in the "tools" folder of the main SDK directory? I am really a noob, can you give me the cliff notes of how to get into ADB, fastboot, etc on the Photon Q in order to do a factory reset? I already have Android SDK installed and completely up to date so that is done. And Fastboot is installed. I'm just having trouble crossing the finish line here... I can get the fastboot page opened in the stock recovery but from there I'm lost. I dont know what to type into the command prompt, in what directory, or what.... Also when I open the command prompt in the SDK folder on the PC with fastboot in the directory and type "adb reboot bootloader" it says "device not found". Maybe (surely) that is the wrong prompt?
FWIW my phone is showing the dead android guy. I didnt do anything besides try and clear up my Play Store download list which required a reboot. The phone never started back up. I dont know how much damage was done or info was lost or whatever, but seeing as how I was rooted but still locked, I had no custom recovery. So no back ups. Is there anything to restore or am I looking at a full wipe and restore?

As abnormal as it seems, your situation seems pretty normal... at least from my shoes. I went through the same scenario... I didn't know what adb was, or fastboot, etc. So, here's what I know
the fastboot commands work even if adb doesnt see it in the list of devices attached. Somehow it just works (as long as the phone is in fastboot mode).
If you're able to get to the fastboot mode, things should be okay. Just open a windows explorer window to the Platform-Tools, hold the shift key and right click on a blank space within the window, then click open command window here.
you should be able to pass any adb (if the phone is on and recognized) or fastboot (if phone is in fastboot mode) commands from that command prompt.
Also, if you have a stock recovery, CMW, or TWRP image, this is the folder to copy those .img files to. Once you get your phone into fastboot mode and its plugged into the computer, just type into the command prompt:
Code:
fastboot flash recovery recovery.img
If you're just looking to reboot the phone into recovery
If you have a CWM or TWRP recovery just replace the recovery.img with whatever the .img file that you have. Also, as a tip instead of writing the entire file name, just press the first couple letters then press the tab key within the command prompt, it should fill in the rest. keep pressing tab until you get to the .img file name you want.
To avoid doing this again, maybe I can help... what were you trying to do to begin with? From the sound of it, you were trying to root the phone with the Root Toolbox Pro but it bricked, and then you tried to reboot into recovery and then got the red android... ?

As abnormal as it seems, your situation seems pretty normal... at least from my shoes. I went through the same scenario... I didn't know what adb was, or fastboot, etc. So, here's what I know
the fastboot commands work even if adb doesnt see it in the list of devices attached. Somehow it just works (as long as the phone is in fastboot mode).
If you're able to get to the fastboot mode, things should be okay. Just open a windows explorer window to the Platform-Tools, hold the shift key and right click on a blank space within the window, then click open command window here.
you should be able to pass any adb (if the phone is on and recognized) or fastboot (if phone is in fastboot mode) commands from that command prompt.
Also, if you have a stock recovery, CMW, or TWRP image, this is the folder to copy those .img files to. Once you get your phone into fastboot mode and its plugged into the computer, just type into the command prompt:
Code:
fastboot flash recovery recovery.img
If you're just looking to reboot the phone into recovery
If you have a CWM or TWRP recovery just replace the recovery.img with whatever the .img file that you have. Also, as a tip instead of writing the entire file name, just press the first couple letters then press the tab key within the command prompt, it should fill in the rest. keep pressing tab until you get to the .img file name you want.

Thanks for the response. So, all I have to do is: go to fastboot and flash a stock recovery image file and it will automatically wipe the phone, cache, everything, and restore the operating system? Sounds awfully easy! I found some stock files in this post : http://forum.xda-developers.com/showthread.php?t=2001226&page=2 Are these the ones you used before?
Last question: I can flash CWM or TWRP but wont be able to access them if my bootloader is locked, correct? So flashing a stock recovery will allow me to have my stock phone back again, locked and un-rooted? I guess if I cant get it to work with the stock recovery then I can unlock the bootloader and do a CWM or TWRP recovery and then flash the stock .img files?
Thanks again for your help. I already had root with the motofail2go method which I like using but seems like when I try and use some generic root feature from apps from the app store that it will crash/brick the phone cuz obviously those apps are generalized and likely to brick certain percentage of devices....
Ok what does this mean? Something with the bootlaoder obviously. Does it need to be unlocked?
Code:
C:\Program Files (x86)\Android\android-sdk\platform-tools>fastboot flash recover
y qrecovery1.img
(bootloader) Variable not supported!
target reported max download size of 31457280 bytes
sending 'recovery' (5962 KB)...
OKAY [ 0.479s]
writing 'recovery'...
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 0.755s
C:\Program Files (x86)\Android\android-sdk\platform-tools>
And on the phone screen it says "invalid image size for partition recovery" twice for both times I tried this method.
You will need to flash the system image as well if you want those, as the recovery image will only flash the recovery. The files in that link are for twrp only... so you'll have to be able to get there first.
With the custom recoveries, I'm not 100% sure whether or not you will be able to use them without being unlocked. I would wait to see if anyone else can answer that question for you, but if you did try it without an unlocked bootloader, you at least have the stock recovery to fall back on if needed.

I'm thinking it could either be that your phone is full and the image you're flashing is too large to fit on the space available...
Or you're trying to flash custom software on a locked phone.
Hopefully someone is able to answer that a little better...

You can't alter the stock recovery (flash a custom recovery like twrp or cwm) in fastboot without having the bootloader unlocked. Your options are to unlock your bootloader, flash custom recovery, create a backup of your current setup, download one of the stock working backups, place it in the backups folder for twrp on your external sd card, and restore one of the known working backups in the development section (befrosty linked to one). Or you could use RSD lite to return to stock using a stock factory firmware flash. That involves connecting your phone to your PC and flashing the phone back to factory stock. Information on RSD Lite and links to the FXZ's can be found here.

[Q] Hard Bricked LG G3.

The issue with my phone.
I can't get into Download mode, computer won't pick it up and non of the buttons work. So I can't just flash a new rom.
It happened when I was trying to install This(I was being stupid and didn't look at the device.) So is there a way to fix it?
Things I tried and have
I have tried ADB, and fast boot they all get stuck waiting for the device (on every port).
I have the laf file. BUT here is the main issue my computer won't pick it up rendering the laf file useless.
I have looked on the forums and all methods purposed. Were for 32 bit computers or didn't work.
Signs of Life (Update One)
It just showed signs of life. It was dead so I charged it and the LED was flashing red and it charged now it is back to black screen and now sign of life though. I tried ADB on my tablet (didn't work) so I know the ADB issue might be my computer. That is good news because it means there is a chance of fixing it.
I am going to try to use ADB on my other computer to see if that works. If it does then there may be a chance of fixing it.

I looked into the zip that you tried to flash, and it looks like it flashed the mmcblk0p5 partition, which on the G3 is aboot (and I believe is why even download mode is broken). You can get a clean aboot.img from the thread here (http://forum.xda-developers.com/att-lg-g3/development/rom-lg-d850-20f-lollipop-5-0-1-extras-t3052041) , but you will have to have some way to flash it. Are you able to get into anything at all on the phone itself, recovery even?
@southern87 : maybe you can provide some insight. I remember in the Lounge a while back you had a broken aboot. Where you ever able to get back to download mode or some other way to repair aboot?

Thanks for responding. I am going to try ADB again but I can't get into recovery mode at the time being.
A similar thing just happened to me, except I got right out of it. Device was completely unresponsive, no download mode, adb nothing, indicative of a hard brick. Scared the **** out of me as I've had it less than 6 hours... Started holding buttons, and it came to life after ~1 minute of power button + volume down. Related? Well maybe not, thought I'd post it here. (TWRP 2.8.5 + Rooted CM12)
True Hard Brick, No OS!
Well I really did it this time. F*cked up big time. Wiped everything on phone, all I have is TWRP which is useless. Nothing. No bootloader, no sideloader, NO files! Guess I'll try to get into download mode.
Anyone have any ideas? Would be greatfull for any help.

They don't put it bAck to stock.. They either will tell you no as you voided warranty or it will be sent off for warranty. They don't flash in store.
You have to have download mode to flash.
So your plugging your phone inTo a non USB 3.0 plug using the OEM LG cable while holding volup and then plugging in the USB cable?

Yes, AT&T said they would replace it for $199.00. Screw that. they gave me the phone # for LG, I will call them & see how much they charge to reinstall the OS. Yes, plugging into 2.0 usb while holding vol up with phone off. No sign of life.

Yes, if only it was that easy.
There are a few things you can try :
1.) Press the Powerbutton for a longer time
If you have a responce like the LG Logo or something like that, you might want to try and plug it to the computer and use the managing software
with which you can emergency reinstall the firmware.
2.) Press Power + Volume Down
If it restarts into the recovery menu, try to find a way to load a flashable stock rom of your handy onto the memory of your phone in order to "reflash" it.
(I don't know how you can do that )
3.) Go to the shop where you bought it and explain your problem, since rooting a LG device is not really easy to detect the chances that your warranty will cover for it are pretty high.

[Q] My One is not booting at all, and does not react when i try to charge it

If i just use my charger, there is no response from the phone. When i try with the laptop, my laptop makes a sound to show that the phone has been plugged in, but the phone does not respond at all. I had a cm12 nightly flashed, and tried to flash Francos kernel on it, which made the phone get stuck on that blue alien logo when booting. After trying various fixes with no results, i just wiped everything ( i had no backups because i am a stupid ****) and then it got stuck on the Oneplus One logo. Now i am trying this http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541[1] and while i used the flash all.bat file, i noticed that cmd just kept showing waiting for device response (or something like that) which was weird, since it had completed some of the previous actions. Then i looked at my phone, with nothing at the screen. And it is now that it does not boot at all (not into the recovery, fast boot, normally, nothing) and does not show anything while i try to charge. What can i do?
Before the cmd process, the phone was showing up as a unit under Computer, but it is not anymore.
Just before, when i plugged it in, windows showed that something had been connected, but it did not know what, so i assume that there are some driver issues or something, though i have installed the qpst driver.
I also made a reddit post about it, where i got some response, but i could not go through with those either https://www.reddit.com/r/oneplus/comments/3bzwel/my_one_is_not_booting_at_all_and_does_not_react/
Do you know what i am doing wrong? Got any other fixes? Thanks in advance.
One get a otg cable then flash any custom rom using ur pen drive or go to adb and connect ur phone and check in device manager if it shows ur phone there or install any adb driver the try that flashall.bat it will surely work!! But I would say get a otg cable

Uh, new problem, i used the toolkit to unlock the bootloader, and i had to use the Ultimate Tool kit to get TWRP on it. When i connect the phone to the pc (windows 7) i keep getting a message saying i have to format the phone before i can use it. When i click that, it says its writing protected. When i boot up the phone, it turns on, and i can go to the home screen (some times) but after a few seconds, it just turns off it self. Sorry for asking for your help again, but do you know of this problem? Google just came up with results for people with battery problems.

I am just going to message you again before i mess up my phone even more, after a lot of hassle, i messed something up and redid the guide in the link you sended to me. According to the Oneplus one toolkit, my bootloader is unlocked. I can not enter fastboot, so i can not get a custom recovery or root. I can not turn on the phone normally either. I can Volume up+power button though, which takes me to the ColorOS RECOVERY screen. I would appreciate your help.

Get rid of the toolkit,they're nothing but trouble. Plus, you don't need it. Plus, they allow you to bypass some very crucial learning experience. Power + volume up should take you to fastboot, not recovery, the button combo for recovery is power + volume down. Are you sure you can't get into fastboot? Is adb working in ColorOS recovery?

Oh brainfart, yup, its volume down+power that goes to the recovery. I just tried volume up+power, and now it goes into fastboot. I did try before, and the vibration was there, but no text on the screen. Not sure what to say about adb, when i launch adb.exe the CMD window just opens up, types a bunch in so fast that i cant read it, and then it closes down. It does the same thing when my phone is not plugged in, so i assume it does not work.

Ok, you're not meant to launch adb.exe like that though. You go to the folder where adb.exe is located, then hold shift and right click the mouse, and select "open command prompt here" from the menu, then you can issue adb commands. The same process goes for using fastboot. Anyway, now that you have access to fastboot all you should need to do is flash the stock images, go to section 8 of my guide thread for instructions:

Thanks a bunch, i got through it this time lol. So just to be sure that i do not end up bricking my phone again, can i just install TWRP, root, then dirty flash the latest CM nightly? I have no idea whats best to go with, and other than long battery life and good performance, i do not really have any needs, so i am thinking the latest cm will be fine. It was a nightly i was running before i bricked the phone actually.

Need help rooting a RCA Voyager Pro RCT6773W42B tablet

Is there an easy way to root this tablet?
The tablet is a RCA Voyager Pro. Model number is RCT6773W42B. It's running Android 5.0.1 Lollipop. Build number is RCT6773W42B-ANDROID5.0-V 19-V1.12.50-KC-B.
I want to root it so I can use the WWE App (No luck with Google Play or 1Mobile or Aptoide). I would so like to use some videogame roms also if possible. That's what I mostly would like to do. Nothing much else. I am not too computer savvy but I do know the basics. So anything that would be pretty easy/simple would be awesome.
Looking for root also. Tried everything to no avail. Hopefully something comes out soon.

Wondershare MobileGo. Free trial, but it works. Download it to pc and connect tab. It will install a "connector" app on the tab, then hit the "one click root" button and let it reboot the tab 3 or 4 times. It may stick on the dog splash screen for a while but don't panic. I did at first, but when it came back up it had root.
Don't use wonder share!!!
This tablet is not root capable out of the box, the reason for this is that the boot loader is locked which prevents any kind of modification of firmware as well as root. Now, I have not unlocked my boot loader yet on mine so I can't tell you if unlocking will allow installation of root but to unlock the boot loader first, read all instructions before attempting and I'm not responsible if your device bricks!
1. Turn device off
2. Hold volume up key then hold power key
3. Let go of power key once it starts booting but continue holding power up key until you in the recovery menu
4. You will see option to reboot to boot loader, navigate to it using volume key then select it using power key
5. You should see fastboot in the corner, now you need android SDK tools and adb ect. Which if you don't have you can google it.
6. Open command prompt from the sdk/adb folder by holding shift, right click, open command prompt.
7. Type adb devices to make sure your device is connected. If not make sure you install correct drivers for this tablet.
8. If everything is good continue by typing "fastboot oem unlock" without quotes it should pop up a screen on the device asking to unlock boot loader or it will automatically unlock it. Now you can try different programs like kingroot or manually install root with command prompt.
I can not confirm this will work as I have not had time to unlock mine yet. And again I'm not responsible for anything that may happen to your device bricked ect

You're not going to be able to unlock it.. there's another thread on this and it's got nothing to do with any human.
Bootloader is locked. Gotta try other stuff. I've had this for months and it's a piece of junk.. frankly, to me, anyway.. it's worthless without root privileges.

... nope. Still no root. Even said "root failed" .. I'm just gonna see if anything else is updated. I've had this tablet for a couple of months thinking there'd at least be a few exploits to use but there's almost zip that I've been able to see. and I'm not the only one that can't unlock the bootloader with fastboot. Not sure what else to think at this point.. but this was a waste of time.
So why is the boot loader non-unlockable?

7. Type adb devices to make sure your device is connected. If not make sure you install correct drivers for this tablet.
8. If everything is good continue by typing "fastboot oem unlock" without quotes it should pop up a screen on the device asking to unlock boot loader or it will automatically unlock it. Now you can try different programs like kingroot or manually install root with command prompt.
I can not confirm this will work as I have not had time to unlock mine yet. And again I'm not responsible for anything that may happen to your device bricked ect

I wouldn't make up a story if it had not rooted. Yes it said "root failed" the first few cycles of rebooting, but after several cycles it rooted. Now... if Wondershare is malware, this may be related... a week or so later the touch screen developed two rectangular "dead" spots that no amount of factory resetting could fix. I could not even type wifi password without rotating it in circles to avoid the dead spots. If you want a decent tablet for under 100, spend 30 more and get the Nextbook Ares 8. Very hard to root as well, but TWRP did the trick.
Wish i could root mine. RCA voyager pro 16gb. Is this bootloader just so hard to crack its not worth it? Or is the device really that crappy that no one wants to bother? I've tried unlocking it manually with adb and i cant select the yes option. Why the hell not? The no option works just great, clicking yes does not a thing. Hitting power after or not. No option for bootloader unlock in the settings. Yes i don't know where to even start when trying to figure it out myself. Justdont think the thing is so worthless it cant be done. I haven't had any issues with it at all, other than not being able to unlock it.

That's exactly why I said you cannot unlock the boot loader.. that's the only way to do it unless you use some dev's app around here that types the same command and tries no matter what.
Regarding it being rooted.. I've been trying for months now.. I'm actually trying again after giving up for a lil' bit.. SRSRoot said they picked it up but that just says it roots and then reboots.. and I see no sign of superuser/supersu or any sort of system apk to manage it, even if the damn app says "unmounting /system" and "remounting /system, rebooting.. Root success!" ... yeah even after that, I saw nothing when it booted back up. Tried Kingo only God knows how many times.. even tried other little exploits, tried to manually root it but unless you have r/w access to /system, which a custom recovery can give.. it won't happen unless someone literally takes what's on the RCA and they more or less just have a pre-rooted stock rom to start.. 5.0.1, whichever.. I haven't done any updates and I'm not gonna try. I'm gonna going to try and cycle through six-seven more times before I just eventually give up. I'm sure something will come along eventually, but right now I'm not getting ****, and not being able to unlock the boot loader isn't much of a help. I can't even load MTK Droid Tools with this, yet, it's got the same 8127 chipset as a rooted Lenovo that I have (running KitKat 4.4.2) .. i was able to install PhilZ with that.. but the boot loader is still locked.. I didn't even try to unlock it.. it's just like how FlashFire operates.. stay in Android but mount only what needs to be mounted.
If anyone see's something that really does root this thing or has a damn /system partition that they can friggin' send to someone (I'd be happy to at least try) to wipe everything and install a custom rom.. I don't know. I'd rather just manually root and then have this as a backup. This is what makes me regret grabbing some RCA even if it was 40 bucks with a keyboard. Useless without superuser permissions.

Oh, and um.. Wondershare just adds a service.. at least under Windows 7 x64.. it's easy to remove so I'm not really worried and.. honestly.. I don't see a correlation between dead pixels and software unless it's immediate impact.

Still no dice with Wondershare, but it does do exactly as you said.. I'm wondering if you were thinking of the correct model and OS. This specific model never had KitKat (4.4.x) for it.. it's 5.0.1 only. Some people mistake this model for the other one with the same NAME but one different thing.. at the end of the model number, the ones that have actually a possibility of being rooted... they have a 22 at the end.
this is a 42. 42B. Now if he has that, then me trying this for the 12th time might have a shot at working. I might just do a factory reset.. like... as it was out of box.. aside from enabling USB debugging mode. I might try a few different drivers as well. It just fails and fails and fails and you know what it suggests to "manually" root? It recommends SuperOneClick which is no longer even used unless you have a really old device..
lol. I'll update you guys if I somehow find something. I'll try all the one-click tools a try but SuperOneClick? I actually have that in my archive but.. I don't really think it's necessary nowadays. If only I could get this damn boot loader unlocked.. I mean there's no way that they'll send anything anyway.. I'll try using MTK Droid Tools due to it having an MT8127 chipset.. every time it just says it can't load adb.. makes no sense to me. I have it installed system-wide with Environment Variables..
I know this thing can be rooted.. it's just gonna take longer, probably a year or more.. mostly because no one even gives a ****. I think it's pretty good if I just had the su binary in /system actually there, even temporarily.. I could easily make it permanent if we have even a glimmer of it for just a few minutes.. that's all I'd need. I'm not a dev but I know my way if I'm given at least SOME time.. Just run an sudaemon and what happens is you can actually remove what's considered "root" regarding the app.. this is actually well-instructed in a post that has to do with removing KingRoot and putting SuperSU on it to replace it. .. and I'm not talking about SuperSUme.. I mean it takes a little bit of knowledge... but not that much.

For the record.. Most don't care about a 30 dollar device with a damn keyboard unless they're literally sitting at a Command Line or using ADB for transfers etc instead of copy/paste. The reason that KitKat/4.4 works here is simple.. It doesn't have any way to patch PIE unless you're rooted already or if you've somehow got your tablet looked at as another device for unlocking the boot loader.. and I do remember, one time, I saw this first install the driver for an HTC One..
it's just an idea.. I'm not responsible if you **** anything up for your tablet. If you don't need root, then just don't worry about it or keep using stuff. PIE just stands for Position Integrated Executable.. and the error it gives every single 5.0+ tablet that has barely anybody looking at it.. well, that's why they're not working.. it literally gives the message when you attempt to root it manually.. "error: only position independent executables (PIE) are supported." ... now there are plenty of threads on here with this and ways to "bypass" it.. hell they even have something called "patch-pie" to flash in a custom recovery.. not the manufacturer. So if you somehow unlock the boot loader and you know what to put on it.. Then you're in. That's usually what happens here.. the methods are fine, they all work, it's just some firmware isn't ever really looked at with brands that have barely any purpose. Most of these types of tablets run 4.4.x on there and that gives them no errors... so it's really easy to root it if you get past it. I've seen it in SRS root right before my eyes and even doing so when trying other things not root-related in adb. Fix that and you'll be able to do it.
Disclaimer: If anything happens to any of your devices as a result of anything in this entire thread, post, or even the links from this entire thread and entire post.. doesn't fall on me, not my fault. If your wife or side girlfriend decides unlocking the boot loader with a hammer, I'm very sorry, but it is not of my doing. This is all for testing purposes. That being said.. I don't see how you screw this up. Don't try to unlock the bootloader, by the way. It's not happening.
The latest KingRoot works. I did a Factory reset prior, I had no clue it'd actually work. just.. clear cache and dalvik basically, install this:
http://forum.xda-developers.com/devdb/project/dl/?id=18893
xda approved obviously... after that, either use Super-SUME or the following guide to remove and replace KingRoot. It's originally made for some Amazon Fire phone but the whole thing is perfect to replace KingRoot and furthermore the correct binaries; At times it'll say it's an incorrect command or that something does not exist.. don't worry about it. It's Ancient but works just fine.. I did this just two days ago. Copy/Paste it line by line, not all at once... or make a script. up to you:

Need Custom Rom for custom rom rct6773w42b
Please where can I found a Custom Rom for RCA tablet 16 GB rct6773w42b, is bricked software for repair this.
Thank in Advance.
Bekel
Anyone have the original rom file? I did a factory reset in recovery and it keeps boot looping back to recovery. Would like to update via sd card option or adb. Please Help!!! I couldn't find anything online, it is the RCT6773W42B.
hey guys my bf found a way to unloclk the bootloader...once in recovery screen...when prompted ...go to bootloader but use the physical keys up/down and press enter to get it to work. volume keys dont work and it works . mines unlocked...just trying to find root solution now,. help??
Bootloader unlocked, full systemless root attained by using Kingoroot PC Version, SuperSU Me Pro to replace the Chinese binaries with proper SuperSU binaries. SuperSU 2.79-R3 installed on Android 6.0.1 Stock ROM. Bootloader is not encrypted. Only requires OEM Unlocking enabled in Developer options, connected to PC with micro USB syncing cable, rebooted into AP Fastboot Mode. Minimal ADB & Fastboot needs to be installed on PC (or the full Android SDK). Open a command prompt in the adb/Fastboot directory if using minimal adb & fastboot and simply type fastboot oem unlock and watch tablet screen for a prompt using the Volume buttons. Contrary to earlier statements this tablet is fully root ready out of the box, and bootloader is definitely not encrypted. Currently working on a TWRP port for this device as well as a deodexed and debloated stock ROM preinjected with root binaries, and optional insecure boot.img with init'd support running stock.
What wonderful work! And many thanks for your efforts. Do you think that your instructions and future ROMs would work with the RCT6873W42KC?

Well, my objective is to modify a stock ROM that can be flashed on any RCA Voyager 7" variant running either Lollipop or Marshmallow. This includes the Voyager, Voyager II and the Voyager Pro. I would like to be able to offer both 5.1 and 6.0.1 ROMs. As long as the filesystem does not in anyway forbid a downgrade in firmware or OS, users running Marshmallow Builds would be able -- with an unlocked bootloader of course -- to flash either a Lollipop or Marshmallow Deodexed, Rooted, & Debloated Stock ROM. A Lollipop OS would offer the advantage of a System-Based Root versus the Systemless method required on the 6.x.x Builds.
Use KingRoot Worked for mine. Looking for custom ROMs

Question HELP PHONE STUCK ON BOOTLOOP AT GOOGLE WRITING AND CANT GET DATA OUT

Hi all,
Im in a desperate and urgent need of help.
My Mrs pixel 7 pro is stuck in a boot loop that restarts 5 seconds after the google writing appears when starting. I wasn't home when it happened but she doesnt really make sure her phone has some battery before turning it on, as soon as she sees 2% she starts it, so im guessing maybe she bricked it while the phone was trying to apply an update when turning it on as she said that the external battery didnt have any juice left inside.
Anyway,
I know i can wipe the phone from recovery mode and make it into a factory reset phone. The issue here is we have over 6000 photos and videos of our son in that phone that she hasnt copied to the external hard drive i gave her for months due to her not liking that her little laptop is slow.
I tried recovery mode Reboot, i tried going into safe mode (no luck as it will go straight into fastboot mode). She doesnt care about a lot of things and obviously she never unlocked the developer setting or bootloader so device state is also locked.
I am begging you, anything any info or advice on how i can get those pictures out of the phone. Is there any way i can flash the stock firmware just to make the phone start and copy them after?
Any possibility or chance or retrieval?
I am willing to pay anyone that can guide me in the right direction as there are over 6 months worth of photos and memories.
Thanks in advance and may the luck be on my side.

If you can enter recovery mode try to sideload the same exact ota package of the rom she's running, maybe that can help. Good luck!

As @acuicultor said;
Here's Googles official OTA updates and instructions etc.
From what i've read briefly and as far as i can gather (still running a stock pixel 7 pro - for the first phone in god knows how long, so i'm not well read on this device but...) if you can sideload the latest OTA update via sideload then you should in theory be able to save the data and boot again. But if you flash full firmware then your device will be wiped in the process (if that's even possible with a locked bootloader).
Very best of luck
EDIT: hmm thinking about it, you won't have enabled USB debugging in dev options, hang on, i'll reboot direct to recovery to see if i can get the device recognised without USB debugging enabled. Sorry to be vague (hopefully someone more experienced with this device will chime in with more advice), like i say, i'm not rooted, flashed with custom rom - nothing, just plain old stock so i've not read up much on proceedures for this device. Bare with me!!
Had another thought, do you or have you been using Google photos to view your images on the device. If so, did you enable backup photos online when you first set the app up? If so, they could be backed up automatically...
Edit: my bad..
Try this link
If that fails just Google 'Google photos sign in'
Just tried from recovery to run some adb cmd's, no joy without enabling debugging 1st
There may be hope... If your photos aren't backed online already from above link...
EDIT:
1. From power off state (make sure the device is charged before apply any ota update) Press vol down and power together. As soon as it boots to google logo, let go of vol down, then power. That will put you in fastboot mode where you use the vol up/down to navigate to Recovery mode and power button to select.
2. Then when you have the screen that says 'no command', press power button and CLICK vol up (releasing vol up straight away but keeping power pressed). That'll take you a blue menu at top of screen.
3. Use vol buttons to navigate to 'apply update from adb'. I have checked using 'adb devices' and 'adb reboot sideload' cmd's on PC and the device is now recognised...
Will write further instructions shortly. (no guarantees this will work tho without losing data...or even if it'll work at all - i suspect the OTA update with just fail to transfer)
OR there is another option, using the same instructions above (1) in fastboot mode use the volume buttons to navigate the menu, power button to select Rescue mode. Then contact your service center for support who will advise/offer support - hopefully, which may end up having to send the device in and still offers no guarantee of preserved data

Following the link it's all explained there:
- no USB-Debugging needed
- booting recovery by key combo
- no loss of any data when using the OTA files
Also turning on USB-Debugging in developer options is not necessary for the recovery. It's enabled by default and moreover the recovery doesn't consider any system settings like disabled/enabled USB-Debugging.

yes, maybe...
FYI: Stock recovery only uses a minimal adbd with a very limited set of commands. That's why some known ADB commands won't work.
