It is possible to enable USB debug from computer? I need to delete some file from the internal memory that causes the problem. I can't connect through adb at all.
I'm trying to fix my secondary phone (Garminfone) that that loads into desktop, but force close launcher and everything else. The only thing that I can do is connect to the computer for file sharing with the phone.
Thank you in advance.
I'm in a bit of a conundrum, myself...
I am attempting to do this, too, but for a totally different reason.
I am a VZW agent trying to extract contacts for a customer from a Moto. RAZR with a completely non-functional touch screen (no display, no function). Phone boots up fine, no sweat. Stock ROM, no backup :crying:, all of the typical means of transfer have been exhausted.
More or less, the only chance I have at succeeding is to either:
Enable USB debugging through some kind of shortcut or trick, or
Somehow, without USB debugging, figure out the user name for the customer's G-mail account (he has two, and cannot remember/doesn't use the one with all his contacts...)
Wouldn't be surprised if it's simply not possible.... but maybe somebody with a bit more knowledge can let us know! :good:
Edit: Hmm, not possible to run adb from the bootloader, but you can run Fastboot commands. None of those seem to be of use for these purposes though...
as mentioned by PhantasmRezound, It's not possible, However. adb is enabled in most recoveries. Also If the device is unlocked ( and you can flash custom recoveries ) in any way you can flash a custom recovery, back up the boot img. pull that off the device or simply put the sdcard in your computer with unpack that, edit the init.rc to start adb. and reflash it with fastboot not quiet what your after but might do the trick.
or
With the non functioning touch screen issue, If the device acts as a usb host, plug a mouse in and away you go
There's always a way.
Thanks for the input...
I appreciate the feedback, but the way I read it... it's either not going to help in this situation, or it's too technical for a noob such as myself and I'm in over my head

Customer's phone is completely stock. Hope I'm following along correctly, but I don't think this is possible without having something like ClockworkMod and pre-existing root access?

Never really tried this... but, I suspect, this won't work... not only does the touch screen not work, but the display is black.
I suppose it could be possible in combination with HDMI-out... but since the HDMI has never been set to "mirroring," I cannot simply plug it in and go (the best and only result I've gotten in this case is the red "M" logo on the screen...)
I would have given up on this hours ago, but it really bothers me when I can't figure out how to do something that appears to be so fundamental and simple...
Thanks for the inputs :good:

Well, I was thinking about this, and I think you can do adb in a stock recovery, should be able to create a backup image with the right software. It all gets a little hazy and wolly on techinical details, so I'm afraid I can't help anyone there.

And you're a noob , I fully understand that my casual, off the cuff, do a,b,c etc reply assumes a lot of technical knowledge, If it's not your phone man, don't stress it too much ..... Just hand it back to them look blankly into the middle distance while shaking your head.....use the following phrase " Nah man you've F*ed this up good, did you not sync it up with your google account at anytime "
Sorry man, I'm drunk, probably shouldn't be at this keyboard now

Unfortunately, Garminfone is a piece of garbage, lol. There's no custom recovery for it. There is nothing I can do now, I guess. I can't get into fastboot or anything because every time I try adb or fastboot it would not recognize the device.

If nothing else, you can do a Factory Reset. You'll lose all data but it will be running again.
Make sure the phone is charged up since this will take a while.
With the phone off, hold down left on the d-pad as you power it on. It will show "Wipe User Data" and then you can let go of the buttons. Just leave it for an hour or so, it will go about wiping and restoring system files from it's own recovery partition.
Also, random Garminfone blog with interesting entries to read while waiting on your phone lol. The person started to develop a port for CWM:
http://mygarminfone.blogspot.com/
PhantasmRezound, I've done tons of wipes but no luck and I'm familiar with the website you posted. Everytime I wipe, I get force process com.android.setupwizard stopped unexpectedly on the phone.
@wolftou
Ok.... A couple more tricks to try for your specific device and then I'm all out of ideas plus it's kinda getting away the original question/topic
1 Android Safe Mode:
Android does have a safemode, exactly the same idea as windows safemode, only needed apps are loaded. This might let you remove the troublesome app.
How to get into it on your device? I have no idea and from my limted research ( google as always ), it appears to vary by manufacturer and probably device. I have booted my tablet into it a couple of times by accident but never really stopped to figure out how, that's not important anyway Just I can confirm this mode exists ( In some androids at least ).
2 Flashing an alternative rom:
Have you tried flashing a different rom? I'm not sure of your model number so I don't whether this is relevant to you but have a look at this thread it looks like you can trigger an update using a sdcard swap trick....
I'm thinking about buying one myself now... just to see what's possible with them, fortunately ( for my wallet at least ) they are not available in the UK and I've got plenty of things to fill my Android addiction for now :laugh:
all answer not similliar the question

Can you create a step-by-step tutorial? I have a LG Leon. Stock. Bluetooth/Wi-Fi disabled. My Google account won't accept. I've been trying to find ways to enable "Developer Options", "USB Debugging" just so I recover access. ADB and most of the programs I've used required USB Debugging, or wireless access.
Hello Everyone, I hope the you can help me with my request, How can I enable the USB debugging mode in android vers. 2.2.2 to 2.3.4
I really had a hard time since my Huawei Ideos s7-105 screen had been broken. I am not sure if the USB debugging was enabled. I have a really have a good reasons why I need to recover the files from my device.
Hoping for your kind response and help.

I'm sorry. I'm in doubt. I have a problem: Navon predator 10 tabs have dropped my gmail account. Adb debug off (or something you see 1-2 programs see something in adb mode but only in device info.If anything else i want always say do not connect. Very strong frp protection.What can I do?
i finally figured out how to get CWM installed and working, after a couple of months of fighting with it, off and on. so, i guessed that meant i have my bootloader unlocked - "wrong!".
i deleted some thing that wasn't supposed to be deleted, then the damned cell network and lan network stopped working (keeps saying com.android.phone has stopped). so i was going to put cyanogenmod on it, because i thought that i could, and just be done with the whole "missing apps" crap. it turns out "just because you CAN put CM on it doesn't mean you CAN put CM on it". i bricked it. i have NO options to "load" or "flash" or "boot" any thing when the phone is booting up. i would love some clarification as to what i CAN do from here.
i would rather install CM and be done with all of this, but i'll take any advice that gets rid of the problem. the biggest problem is understanding how to put CM on your phone, or to do any thing at all like that, when you cant get into any kind of recovery / boot menu, even though you ARE rooted... i don't care if i have to install cyanogenmod or some one else's CWM backup, i just don't know HOW to do it - especially with no windows (only linux). it's a rooted p769v20d (originally p769v10g).
thanks

i was going to try some stuff mentioned in other threads, but i don't have access to a windows computer - and i don't think i need to root my phone again any way, considering it is still rooted.

fwiw, regarding the mysterious deleted app:
i lose my internet signal as soon as it says "com.android.phone has stopped", then i get it back again right before it says that message again - it ALSO shows a cell-phone signal right before that message. this repeats over and over and over every few seconds - aggravating as hell...
here's the apps that i still have installed: http://forum.xda-developers.com/showthread.php?p=45774770

Nice thread title. That is how I am feeling right now with this phone. I feel like calling tech care and yell at them for a bit to vent. Anyway, why not install fastboot for Linux and flash the ics u and x? I uploaded my u and x folder in the Unlock Bootloader for Noobs thread. Then, flash the 20h.....oh, dang.... sorry. Forgot.... no Windows. Maybe do the built-in restore by holding the volume down, home and power keys?

thanks, but i think i finally got it working. i never knew, after all this time, that after you do the l9recoveryinstaller, at the reboot, there are no cues to tell when when to hit some buttons, and it's not clear what buttons to hit. here's what i did, and, so far, its progress:
1: be rooted
2: install busy box, completely
3: install l9recoveryinstaller
4: reboot
5: after you see the LG logo, hold vol-down until you see the flashing lights (i thought you see the flashing lights and THEN you hit vol-down, but i was wrong).
still fighting to get a rooted rom installed ...
if i choose "install zip from external sdcard" is says:
"finding update ... opening update ... installing update ...installation aborted".
if i choose "restore" instead of "install" it will not let me select any thing, it just keeps saying file not found, when i try to select any further options, whether "restore" or "restore from external sdcard" or "advanced restore from external sdcard". and i already checked to make sure the sdcard was mounted...

I think your phone bootloader is locked, you cannot flash any custom rom zip file. It will soft brick your phone.
Please restore P769 CWM back from this thread http://forum.xda-developers.com/showthread.php?t=2136204. Download backup file and unbzip it. Put extract files in your sdcard /clockworkmod/backup/2013-08-30.12.00.00 folder. Extract file should contain several .img, .tar, .a, .log and .md5

Well correct me if I am wrong, but I guess you "only" deleted some system files, right? Do you remember which ones were the ones? Or at least the folder they were in? Then you only need to extract that stuff from a kdz/ the bin file and push them on your phone using adb or maybe even the dd command.
Maybe if someone is kind enough, he ll probably provide you with the files you need. And cmiiw, but I guess you deleted stuff from /system/app...

Lol, you are a Linux user, you should know how to get your hands on a windows.iso
However, i would recommend using a portable windows xp (bootable usb)
VR is not the best option IMO
You will need this program http://unetbootin.sourceforge.net/

Sorry I can't provide a link to the iso but do a google search for

It's depend on what method you use. You can flash kdz using offline method here http://forum.xda-developers.com/showthread.php?t=2085344
or use LG mobile support tools from LG website. If you choose this you don't need to download any kdz. It'll download kdz automatically from LG server then flash it on your phone. It take about an hour or two.

thats awesome - i wonder if i can get by with using that on wine on linux, instead of borrowing a windows computer... i'm gonna try it...
well, the verdict is in, on this one: i'm screwed. i've tried and tried and tried and tried and tried and tried and tried and tried and tried and tried and tried and tried, and i can NOT flash this damned phone. it's BRICKED.
i borrowed / hijacked my brother's computer (windows7), all day. i tried a few different things - i even tried the same way i flashed it to update it ( http://forum.xda-developers.com/showthread.php?t=2356536 ), which was worthless to unbrick it.
the problem in every case was that every time the damned flasher got so far along it would "lose the connection to the phone". drivers installed, etc, etc, no difference. i suspect its because i couldnt connect it in all the various modes (mtp ptp etc), since the ONLY way it would connect is in "software upgrade mode".
i had to buy another phone, won't have it till tuesday. lesson learned: NEVER buy a phone that didn't come from samsung... you just can't do what you want with them, without a lot of time, patience, experience, and a windows computer.
thanks for all the help.

Did you try to recover your phone with LG mobile support tool. It can reinstall rom in almost any soft-brick case. Please try it if you haven't try it yet. Many people restore their phone by that software. The steps are
- Download LG mobile support tool from LG web site
- Boot you phone to S/W update mode
- Run Tool and select recover phone
- Wait about 1-2 hours to download and flash
If it's not hardware problem, this should solve your problem

i never found that on their website, and i looked quite a few times. however, i noticed when i used the b2clientsetup.exe that if i run it without running the shttp server first, that it downloads a support tool from the net, which does not work - keeps saying phone lost connection. not sure if its the same tool.

In my country (RO) there are some GSM Repair Centers. You should not give up and you should go to them. Par example, I flashed an HTC Mozart when the battery was dead and I bricked it (idiot, I know). I went to a shop like the ones mentioned above and I think he said that he has to flash the phone using a JTAG or something like that (I know that he has to open the phone to reach it's motherboard, solder some **** out there and... flash I guess). The whole thing was about ~20E. Anyway, keep digging, maybe you'll eventually find something that works for you. If not, go to someone who can "force flash" it and maybe you can save the device.
Could someone give me a super quick guide on how to get this on my phone? I coming from years of Samsung phones and never owned a Sony before or know anything about it. I have CM on all my Samsung devices for years and simply want a CM ROM in the Z and get it done with with. I picked up a 99% like new second-hand Ultra Z LTE C6833 today, has stock 5.02 and I don't have a clue how to get this flashed in the easiest and simplest way possible. As for locked or not bootloader, I also don't have a clue. First step which is to install TWRP I immediately got stuck because the links posted are dead (teamw.in/project/twrp2/219)
Without wanting to waste anyone's time, if someone could give me the simplest and most painless info on how to get the Z flashed, I'd be super appreciative. The threads on this phone are in the hundreds at this point and I read all sorts of very confusing and contradictory info. I worry to kill or brick it immediately before I even get started.
Thanks much in advance
Read. Thats my tip.
Every sony device past 2011 works the same way.
Look at different xperia forums, for example at the Z1 section, Z2, Z3 etc.
Look at the rooting guides. Unlock guides. Ta backup guide. Just read and read.
Dont just look at the first guide and jump right in.. read first.
Explore the Xda forum. You will find the guides im talking about. im on my phone.. a bit difficult to post links atm
Much good information can be found here

You can check if the bootloader is unlocked or locked by opening the dialer and entering *#*#7378423#*#*. Then tap "Service Info" and then "Configuration". It'll either say "Bootloader unlocked: Yes", or "Bootloader unlock allowed: Yes/No". If it says NO on the latter, then you can't unlock the bootloader and you're pretty much screwed. Bell Canada devices have locked bootloaders, and I believe it's the same with UK O2. Chances are that you can unlock it, but you could of course be really unlucky.
If you can unlock the bootloader, then your Ultra will pretty much behave like a Nexus device when it comes to rooting and stuff like that. Just flash a custom kernel with recovery, like NUT's Dual Recovery (with CWM and TWRP), then flash SuperSU, and you'll have recovery and root. Next step is to flash CM12.1 and you're done. It's very easy once you have recovery.

Thanks MUCH for the detailed info!
I checked the bootloader info as you said and it's not unlocked, but can be done. It seems a daunting task but let me start by trying to get it done. Hopefully I won't screw-up the phone. I'm searching how to do it as there seem to be several ways.. After I complete the unlocking (let's hope) I'll report back and try jump on the next steps. Probably will have some follow-up doubts or questions.. this is all a very different and more complex process than the Samsung devices I've owned that never required any of this crazy gymnastics..
Anyway, thanks again very much and keep you posted!

I'm searching how to do it as there seem to be several ways.. After I complete the unlocking (let's hope) I'll report back and try jump on the next steps. Probably will have some follow-up doubts or questions.. this is all a very different and more complex process than the Samsung devices I've owned that never required any of this crazy gymnastics..
Anyway, thanks again very much and keep you posted!

I'll give you the short guide:
- Go to this (offical Sony) site and give them your IMEI and whatnot
- Wait a couple of minutes, and you'll receive a key
- Now, there are two ways to unlock the bootloader - both equally official, but the easiest one is to use Flashtool.
- Hit the "BLU" button and enter the key you got fra Sony. You only have to do this once.
- Once this is done, you can start flashing a kernel with recovery and flash whatever you'd like.
I'll help you along the way if you need to, so don't be afraid to ask any questions. Start by unlocking the bootloader, and I'll be here if you need any help.

Hello I am new to Sony too and I have a question. If I unlock the bootloader root flash custom roms and then decide to get back to stock and lock the bootloader will my warranty be voided?

Yes, and that's why it's a good idea to backup your TA folder, which contains the DRM keys. Once you unlock the bootloader, these keys disappears, and that's why it's a good idea to make a backup of them. There are a couple of tools that does this for you, and you can find them in the cross-development section.

Thank you very much!
Well so far EVERYTHING HAS BEEN A TOTAL NIGHTMARE! Nothing I try to do works!
First I installed flashtool, latest version. Im running Windows 7 64bit. It was a nightmare to get flashtool downloaded and installed. After I finally got it installed, ot took another hour updating itself and syncing stuff. When it finally finished and while holding down the Volume Down key I connected the phone to the PC via USB cable, Immediately I get an error of device driver errors. flashtool gives me also several errors. Then I tried to install the Flashtool-drivers-1.1-20130911. Then another problem, the drivers dont install at all with a message "DPinst.exe cannot execute on your operating system". That's it, finished! When I go to the Windows Device Manager, all I see is an exclamation mark under S1 Service.
So then I tried the FastBoot method. Also no luck. While holding down the Volume Up key I connected the phone to the PC via USB cable, the phone's blue light turns on, and again I get a DRIVER NOT INSTALLED ERROR. My computer refuses to recognize the phone and the device driver is never installed . The Windows Device Manager shows an exclamation mark under S1Boot FastBoot.
Then I tried the Sony way and installed the Android SDK!!!!! Immediately I find I need to download more crap, thie time the JRE Development Kit! Takes me 3 hours do download this with my useless internet connection. At this point I am already ready to throw my laptop out the window and break the stupid phone in a million pieces!
But then, there is the next problem. After all downloaded and installed, before I can even started I get stuck again, because Im supposed to go to the android SDK folder c:\android-sdk\extras\google\usb_driver and replace/install the fastboot drivers “android_winusb.inf”.. well, I dont have an extras or google or usb_driver folder on my SDK installed folder! NOTHING! THIS IS ALL RIDICULOUS!
Finally I searched everywhere on the internet for other possible Ultra Z drivers. I ft to Sony's own site and found Xperia Z Ultra (C6833, C6806, and C6843) drivers, Xperia Z Ultra (XL39h) drivers, Xperia Z Ultra (SOL24) drivers, Xperia Z Ultra (SGP412) drivers and others.. this is all crazy what a nightmare of mess and miss-information everywhere about this phone! Anyway, I tried all of them. None works.
I am so frustrated and desperate. My God! Cant get anything done. Nothing.................................. I cant believe this..
UPDATE: I give-up. Ive spent the whole day and downloaded and installed GIGS of apps and software and drivers. Nothing communicates with this useless phone. Im done.
Could anyone give me advice if its there is an alternate way to, root install a recover and flash this piece of **** phone without unlocking the bootloader which basically I cant do? If not, it will fly out the window asap, I cant deal with this ridiculous drama. Years of handling and flashing all sorts of hardware COMBINED, never gave me 1/10th of the misery and headaches this hardware has given me in one day. Xperia, never again..
By the way, Sony's "AMAZING" PC Companion app is so great and fantastic that it doesn't even have an uninstaller! No joke! Once in the computer, crawling endless directories with all sorts of files, drivers and registry entries, it will NEVER come out again. All is amazing..
You did the opposite of what I advised you to do. You did not read correct guides.
Q:Ask yourself what do you want to achieve?
You wrote in your first post "if someone could give me the simplest and most painless info on how to get the Z flashed".
Q:My counterquestion is why? Is your phones software unstable? Are you curious to learn to modify the devices software?
A:If your device is unstable. Please do a factory reset.
Q:Are you curious to learn how to modify the software?
A:Then collect information. Read. Set a timer for how long you will spend learning. Let say 45 minutes.
When 45 minutes has passed. STOP.
Take a break. Do something else and continue the next day. Repeat until you are confident to try a simple operation
For example: learn how to use adb and fastboot. Learn the commands. What they do.
I can not stretch enough how important it is to read and learn before you jump into things.
I do not see why I or anyone here should help you to unlock your bootloader. Because you do not have a clear purpose or knowledge how to do this.

Just to briefly correct you: I'm the type of guy that has NEVER gotten a virus on a computer. I'm the type of guy that has rooted, flashed and played around with phones for many years with more or less degree of difficulties, but always successful. I'm the type of guy that has helped many many people in this community with their hardware, when I know how. I'm the type of guy that has knows many things about the works of Samsung devices that I have used for many years and have never had an issue learning what's needed. I am the type of guy always ready to offer friendly advice when someone is in need of something I may offer help with. Finally, I am the kind of guy that has a Dell laptop, running Windows 7 64bit, that by whatever reason refuses to install the proper drivers for the Ultra Z, or the kind of guy that maybe has a flawed Ultra Z. After all, it's a second hand unit and about 2 years old, despite that it looks new.
So, the only thing this type of guy can do, is 1) try a different computer to see if the communications with the phone work, and if not, check the phone because obviously that's where the only place the problem can come from. To try different USB cables and do phone resets, that I did today several times. I learned those basics the first day of my flashing life, long long ago.
There is NOTHING to read or learn or do, when there is no communication between the phone and the computer that connects to it. You seem not to understand the very basics of the problem here is not lack of reading, instead is only lack data flow between devices.
Anyway, thanks for the constructive advice!
2 extra things: all the tools, apps and drivers you have suggested, I have them all. All the procedures, steps, folders where stuff is and goes.. I've done all. I learn very quickly. The issue is none of that.. the issue is, no driver for this phone will install on my laptop, for whatever reason. Is that simple.
And then there is another issue.. for you, and most people on XDA, downloading and getting "stuff" is a breeze. But not me. Where I am, XDA is blocked, and even with a VPN, hardly works. To reply to you or just log-in, sometimes is an hour. And most file hosts? Mega? Rapidgator.net? Zippy share?.. a few hundred others? Well.. they doesn't work. Uploaded.net.. Mediafire.. Google Drive.. AndroidFile Host, and just about everything else, all DON'T WORK. All blocked. So are blocked most of the VPNs now. So, while for you, go here, get this, download that, is all a piece of cake, for me, is not. Most things to get download are truly a nightmare. And when it comes to download a ROM or any 2 or 3 hundred Mg files, sometimes takes me days of endless wait and interrupted downloads. I live in a crazy country called China, where all Google stuff, Android included, is forbidden, and all around it.. XDA included.
So, talk is easy. But when access to simple and basic information is so difficult to get and everything comes at a premium, life is really a bit more complicated than maybe you can imagine. So...... yeah, help is very much appreciated indeed, in the same way I am always willing to help others when I can, without calling out their lack or reading or question their abilities to follow my advice
Alright, that was quite painful to read, not because of something wrong you wrote, but because I've been there too. I don't know what device you had prior to the Ultra, but just forget what you learned from that device.
Just sit down, relax and figure out what you're trying to do, and then how to maybe achieve it. Yes, I do understand that your laptop doesn't cooperate at all, but that's just technology. Of course it won't work when it should. We've all been there.
1. Set up your computer to be able to communicate with your Ultra. Installing the SDK is overkill since the only thing from the SDK you need is Fastboot and ADB drivers. You can easily install those two by installing this tiny tool that does it for you.
Fastboot and ADB is now installed.
2. Install Flashtool. You've already done this. Connect your Ultra and open Flashtool. Flashtool should grab and set things up for the Z Ultra automatically. This should only take 5-30 seconds. Not three hours. The device should still be powered on at this stage.
3. Okay, now you have Flashtool installed, and it recognizes your Ultra. Next step is to go to that Sony site I linked to, to get the unlock key. Fill in the required info, and you'll get the key sent on your email. Don't misplace it.
4. Go back to Flashtool, hit the "BLU" button, paste the key in, and that's it. Don't set the device into fastboot or flashmode until Flashmode asks you to do it. Fastboot can be active and connected forever, but Flashmode will disconnect by itself after a minute or so.
5. Your bootloader is now unlocked. This means that you're free to do whatever you'd like to do with it. Xperia devices do not come with a default recovery system, so we'll have to flash a custom kernel that includes a recovery. You can find them in the dev section. Once you've flashed or hotbooted a custom kernel with CWM or TWRP, you're free to root by flashing SuperSU, and flash whatever ROM you'd like to flash.
It's very easy to deal with Xperia devices once you have things set up (mainly Flashtool), and the basic steps are:
- Unlock bootloader (one time thing)
- Flash custom kernel
- Done
It's the same procedure as Nexus devices, only that we have to use special tools to unlock our bootloaders, while Nexus' use one command in a terminal. The issue here though is the tools, and not the process, and I feel your pain. I really do. It would've been so much easier if I could just show up at your door, do it for you, and leave

Klaos3000, you are great. Difficult to find words to thank you the time you take to try help me out. Really much appreciated. It's almost 1AM my local time here and tomorrow I will give a try to all you suggest me step by step. If I run into additional difficulties, I will try use another computer. Maybe is my specific laptop with my windows installation that is being stupid with the Ultra Z hardware. I have installed endless drivers for HTC, LG and mainly Samsung phones and tabs, and have never had any difficulty.. just last week I installed drivers for a friend's new Galaxy Tab S2, got a recovery in, got it rooted and manually cleaned of a lot of useless samsung system bloat stock apps and crap, all about 20 minutes. Hard to understand why with an Xperia phone, things are so complicated. Anyway, tomorrow will follow your advice and report back.
Again, thanks a lot for your help
Klaos3000, despite being so late, I decided to give this another try and follow your steps.
But I Immediately run into similar problems.. I CANNOT get drivers installed.
1. I have downloaded and installed Minimal ADB and Fastboot as you suggested.
2. I have flashtool-0.9.19.7 installed and did the 0.9.19.8 upgrade by updating the x10flasher.jar file.
3. Now you suggest I connect my phone and open Flashtool. But connect my phone how? Boot it up? USB debugging on or off? Or you mean connect the phone turned off and then on press Volume up? Or press Volume down?
I tried all this, and again I get a device driver error. Because there are NO DRIVERS installed for the phone. This is same problem as before. And if I go to the drivers folder inside Flashtool and try install the drives, I immediately get an error that they cant be installed in my operating system.
I am completely stuck as before in this very simple step.
Attached screnshots when I enter Flashmode:
And this is what happens when I try install drivers from C:\Flashtool\drivers:
And if I try go to FastBoot Mode with the phone's blue light on (Volume up + connect USB Cable) this is what I get:
UPDATE:
I have finally unlocked the bootloader, using the Fastboot method! I still could not get the Flashtool drivers to recognize my phone, but the FastBoot ADB drivers installed without a problem. 2 things Ive learned with this experience I want share with anyone in the future that has similar difficulties:
1) I switched to a friend's old laptop with Windows XP. Under XP, FastBoot ADB drivers installed at the first time and absolutely zero problems.
2) I used a USB 2.0 port! If connected to a USB 3.0 port, another cascade of new problems immediately arise.
So that's it. I want thank VERY MUCH everyone in this thread that was so kind to try and help me as much as possible. I would not have gotten this done with it
My next step is to install a recovery from:
http://forum.xda-developers.com/showthread.php?t=2261606
But I only see downloadable versions for looked bootloaders. Also, I want to flash a custom CM based ROM next and see a warning regarding Unlocked Bootloader with CyanogenMod, AOSP and OmniRom that the kernel needs be repack to replace the built in recovery with XZDualRecovery or things will either not work at all or require unexpected operating instructions. So again, I am extremely confused as what files to choose and what to do and worry to look for the wrong thing and worry to make a catastrophic mistake. And also I have no idea what method I should use:
- ZU-lockeddualrecovery2.8.21-RELEASE.flashable
- ZU-lockeddualrecovery2.8.21-RELEASE.installer
Thanks again for the advice and the feedback in all this
Well, I tried all the "one-click" apps (I don't care if they sell my info) and none work so far...
So it's time to consult XDA. Did it years ago, doin' it now. I'm new here, but you will be happy to know I read all the rules.
Time to fix this chinese piece of crap! This is the only device I own, and I can post all the processor and system info if needed. IDK if the bootload is unlocked or not, but a guy in another post for another RCA tablet mentioned he owned this same one and they said he might not need to unlock it. So IDK. NOTE I HAVE RCT6513W87 WITH NO "M" ON THE END. DIFFERENT MODEL.
So first, what am I gonna need? USB M-2-M?
I don't have any experience using ADB, however.
Don't really know what I'm doing so far.

I just spent the last few hours attempting to connect it to my Windows 10 PC. Nothing. 100% Impossible. Modified registry, edited drivers, tried modified google drivers but it kept saying "Windows has determined that you already have the best drivers for this device" trieda few workarounds for that. Damn, really want this rooted but it seems impossible.:crying:

Yeah, been there. However there should be a way. There's a five second window of opportunity when you have the USB connected, have the PC in the device manager. I'm willing to bet most of the process is the same when it comes to accessing the device according to Smartman Vartans tutorial for the RCA Viking Pro. I have that, the version before it and I have the Galileo, Build Number (RCT6513W87-ANDROID6.0-V21-V1.23.30-W02). It's about time I do something with it. His method is incredibly complex from the looks of it. But I'm willing to get root at least. Sounds like it's time for experimenting. Okay, I'm in. I'll see if I can pull some resources. Enable Developer settings (tap build 7 times). In The Developer settings turn it on. Turn on OEM Unlocking (to unlock the Bootloader). Turn on USB Debugging. Go down to Select USB configuration and make sure it's at MTP.

[/COLOR]The Viking Pro used a SP splash tool to see the device , I've heard it works on this. Also listed was a driver. I'll go look for the frimware hopefully we both have the same. Then there's one thing that's been making me wonder. The Viking Pro uses the exact same motherboard and components as the Acer Icona, which has current 8.0 firmware. I don't see why for the life of me why I can't float that firmware in the RCA. It's an idea. But here's the Viking Pro link,

Wow!
Hey thanks, I saw you on another forum (unless Casper Young is a common name?) and you said something about usb serials being locked, but I will defintely look into this! THX!
EDIT: BTW, my build number is V08- 1.15.20
I'll bet that's me, and my actual name. Howdy Thar. Yes USB Serials appear locked by manufactuer. When I dig into the data section of my rooted Viking Pro I happened to notice they were somehow locked and I was unable to follow the pathway. I can still try. But what I think you're trying to do is gain access via USB, correct? I talked to Smartman Vartan long ago and we have one interesting delima. Okay so we can gain access, but then what? It's not like we can just throw anything in it. I have 3 different devices The Maven Pro, the Viking Pro (both are rooted) and I got this Galileo Pro. Long story short, I was looking for compatible firmware. Went old school, look at the specs. Not the ordinary ones you find anywhere, the real specs. Go here, https://www.productchart.com/tablets/11121 sign up, yeah, WOW! Okay so I compare a few things, (I'm off exploring the Viking Pro), didn't have the galileo yet. Now, come to find out, the Viking has the same exact motherboard and components as the Acer Icona 10.1 (I forget which specific one). Hmmmm, now that's intresting. Can I, just toss it in there? I don't see why not. Others here suggest otherwise. I don't flash anything without back-up That's item #1 we need if you're gonna follow along. #2? The SP Flash Tool. I have those. Now I gotta open this puppy up and check out the motherboard. Gimmie a couple days I'll get back.
I wish we could use Odin3 but here's what I got For starters. I'll write out the tutorial if I get anywhere. How to run the SP Flash Tool:

If your intention is only to root the device you must first enable Developer Settings and then enable OEM unlock which gives you access to the Bootloader. Now you can flash in a custom recovery and then you will be able to root the device. You cannot do so by any other means. It will reject any attempt to root unless the Bootloader is unlocked!

Ok, I have everything, I THINK I installed the drivers, but I am waiting for it to charge to be sure. Can you be a little more clear on your instructions here? Do I flash the firmware? What order do I do everything? Custom Recovery first? Firmware first? How do I unlock the bootloader when it STILL doesn't regonize the device in ADB?
BTW, I installed the drivers by the SmartmanVartan method.

Yesterday, I tried flashing the firmware you linked to, and well, RIP. Bricked. Yours had build number .22, while I needed .15. So now I don't know if I can fix it. BTW Drivers worked and everything else. Did "fastboot oem unlock" and got to the "Do you want to unlock bootloader?" page, BUT the volume keys weren't programmed into it so you can't confirm nor deny. The bootloader needs to patched.
But before I get there, I need you to find a firmware that has .15 in the middle like this: x.15.x
Please, you are my only hope.
PS: I contacted Bogram, who patched the bootloader on the viking pro. If I can get the right firmware, then I can send it to him so he can patch it and I'm there. IF HE DOES IT.
TIA!
Brick
BTW, I think it might be a hard brick. I don't know much about bricking, but it won't even turn on, and the charging light comes on if even it isn't plugged into the outlet (SUPER WEIRD)
EDIT: When flashing, it never said completed. I waited for a really long time and then clicked stop. I really don't know too much of what I'm doing

Wow try slowing down a bit. Sorry to hear your having difficulties with your tablet. I didn't expect you to flash it yet. No-one has provided anything to flash into it yet, I thought we were going to go looking. I'm hoping there can be a way to get past a brick. I've been reluctant to flash any of my devices for exactly the reason that you're dealing with. I didn't think to post what my firmware build number was, I'll edit that in.
I'll look for your firmware or ask RCA for it. This might take a bit. What color light is showing. And somehow try getting it to boot to recovery. Where you can reset it. Thats where the back-up is supposed to go also. There can be a variety of combinations to get there. Isn't there a reset hole to the left and a little below the micro sd slot. You may have to have it docked to get to recovery (the Viking Pro is like that). I'll do some research and see what I can find.

Whoops. Yeah I'm sorry, I've always been a bit hasty. I have looked for my firmware, but would RCA give it to you? I forgot to say my processor is MT6513. Not MT6127.
Well, thanks for spending so much of your time for me though. You have been very helpful. For me, bricking it was a learning experience. I learned a LOT about how android works messing with this tablet, and come on, it was a crap-let I only decided to
"hack" it once we ordered a new one (The keyboard doesn't work anymore)
The day I did it, I got frustrated I couldn't unlock the bootloader, so I wanted to do something else, without thinking about it. LOL. Well, more learning for me!
The only light it ever does it bright blue, and it no longer does it without being plugged into the outlet. Oddly enough, I didn't think to use the reset button, and in device manager it still shows up as preloader device, even though I suspected to be the preloader to be corrupted. There really shouldn't be a reason it won't start now. Also for some reason, ADB never has regonized this device, unless in fastboot mode.

Welcome to the place where you gotta play it safe. Yes RCA does provide the firmware, here;s your like for that.
https://stockromfiles.com/download-rca-stock-rom/
Now what I don't understand is why RCA implies there's no different versions of the software and you have a possible bricked device. I have a few articles that say even if your bricked you can flash in the software. Here's the tutorial for using the SP flash tool and another software location. The Tutorial makes me wonder though because if you look at steps 1, 2 and 3 they're questionable, especially #3. I'll get back to you in a bit, gotta chore to do.

Oh, and you have yet to learn about playing with Androids These RCAs don't count. They're completely different from flashing a Samsung Galaxy or any other Androids.

I'm stuck on waiting for all devices in adb.. My phone screen has a menu with three choices, one of them is flash unlock.bin. Should I keep waiting for all devices for how long in adb?
What procedure are you using to unlock? The WTF process is the one that I believe has worked the best for most people... and that doesn't have anything special on the phone screen, so I'm thinking you're using some app or script?

Yea, I'm following that one. I read somewhere about AMD PCs causing problems. My phone shows when I use adb devices. So should I be a little more patient or what?
No, the processes are quick. AMD Ryzens typically have issues, but it's only because of the USB driver they use. I've heard a few Intels have issues sometimes as well.
The key is, you just need to try other computers... this is the "hardest" thing to do, but it's really the only solution to that issue. The process takes under a second, so it's not a patience issue.
For the record, my older laptop with an AMD A9 CPU did the process fine... so, again, it's not a CPU issue, but a driver issue for the USB, apparently...

Some people had to use 2 or 3 computers. An older one with Intel CPU works best (especially if it has USB 2.0), but yes an AMD can work. As noted by @schwinn8 Ryzens are no go. One guy was upset because he had superfast gaming computer and we kept telling him to try another computer. He borrowed his brother's mediocre laptop and BOOM, worked. Another guy dug some old laptop out of his closet and it worked.
Thanks for the reply...i was just reading about adb making sure it wasn't something i was doing wrong. Even tried on an old iMac that i had installed linux on. "Waiting for device..." So..still reading and learning to be patient. Thank you

Also, try the steps mentioned in Wtf troubleshooting section.
Other than that you may have to mess around in the device manager section to see if the phone is detected properly or not.
(if there's a problem with the driver the device will show up as unknown android device or something)

You said "patient"... just to reiterate, this process doesn't take longer on a computer that says "waiting for device". It's a fast process, so if it's not happening within a few seconds, it won't work on that setup, period. Don't waste your time waiting - get another machine/cable/etc (check the troubleshooting steps to find other possible issues... the computer is usually the biggest problem to overcome, but the most successful).
Good news, i unlocked my phone and installed twrp, then i had to stop the process (wtf)
i still need to make a backup in TWRP and flash two more files from wtf notes. I cannot seem to be able to reboot into TWRP from ADB. thanks in advance
The oem is greyed out in developer mode and says its unlocked. Idk?
Glad to hear you got it unlocked.
In the WTF post it says that the developer mode may remain grayed out after being flipped... this is normal. It comes back after some time. Of course, you don't want to toggle it again anyway, since you're unlocked...
When i go to use an app to boot into twrp..it tells me its not rooted.

Used getvar..unlocked.
Well its done..used an old hp A6 with linuxmint. I found linux to be straightforward and easy when trying to root my phone. No jumping thru hoops and juggling stuff.
Any recommendations for remodeling the phone? Boot to twrp..roms..ect?

Bootloader unlocked is not rooted. It's just the prerequisite to being rooted. Then you install TWRP custom recovery and then use that to flash Magisk. It's all in the WTF Instructions. Also be sure to use the version of Magisk in the WTF Instructions, at least initially.
Thanks..ive got magisk from the instructions. It wants to update..should?
Once you are booted into Android, you can update Magisk to some degree. I forget the last version I had but I recall I could go to 20.x or something without issue. But there is always a risk of having issues if you update to the latest version... so be prepared to go back to the one on the WTF thread if the phone has issues. In other words, don't do this last minute or without a PC to work from... because it could fail.
The only time you have to use the old Magisk is during that first boot with it... once you're booted through, you have been able to update to newer versions. But unless you need some specific feature of the newest version, I might suggest leaving it alone...
I read somewhere..when i upgrade on US 998 20b, i need to move up to 20c?
Also, do i use the "twrp version. 20c"?
