[HELP] Cannot factory reset a Kyocera Hydro Wave (C6740N) on Metro PCS

Greetings to all the developers and registered users on this site... Yes, this is my first post, but I read here pretty often and I used the search function, trust me! Seriously, I've tried all I could and I am at my wits end, but this is technology, we can't let it own us, we gotta continue owning it and that's what online communities like xda help us do, so thanks for all your past, present, and future contributions here. So I got this Metro PCS Kyocera Hydro Wave (C6740N) that I can't factory reset for a number of reasons, but mainly because I believe that there is either no boot-loader or no recovery partition as a result of Metro PCS flashing the ROM...
Anyway, lets get to the juice:
- Device powers on/off, but no combo of Vol -/+ and Power buttons bring up a recovery menu or anything (holding any combo down just boot-loops)
- Device has no SIM and no micro SD card, and the battery is not removable
- Device is locked... Like, pattern-locked/google account info/too many attempts/yada yada yada
- Device has no data and no WiFi connection active, so I could not use the google account to get past the lockscreen
- Device does not have USB debugging enabled/Google drivers for ADB do not work (Windows 7 auto-detects when I plug in the phone and installs a generic Microsoft driver which cannot be removed even after uninstalling the device, and also I pointed the Device Manager to the correct Google drivers I installed with the Android SDK Tools, as well as the Samsung Naked Universal Drivers I found on this forum, and Kyocera ADB drivers I found through Google which all failed, Windows returned a message stating that the most up-to-date or best driver for this device is already installed)
What I've tried (everything possible really):
- Hard reset/Recovery from phone: FAILED
- Connect to Linux and install ADB, then tried running the adb shell, adb devices, fastboot devices, etc but phone not detected: FAILED
- Connect to Windows 7 and install ADB (Android SDK Tools), I literally checked every single box and installed Platform-tools, google drivers, everything, got to the command prompt as admin, cd to the ADB directory, ran same commands as in linux, also tried commands on several forums and posts like adb shell rm /data/system/gesture.key to remove the lock but everything: FAILED
- Connect to Windows 7 and attempt to install proper drivers using RootGenius, MoboRobo, PDAnet, and several other suggestions which all were oblivious/unable to detect the device despite Windows recognizing it, so they all: FAILED
- Connect to Windows 7 and attempt running ADB through a Cygwin terminal, but the command "sudo" was not recognized/not valid, so: FAILED
- Connect to Windows 7 and use XRYViewer to extract data from the phone, possibly to see the system files and get an actual understanding of what everybody is saying you need to mount from the recovery partition, but no clue how to use this, since I can't find an XRY file in the internal storage, so: FAILED
- Connect to Windows 7 and access data/recover data from device using "Wondershare Dr.Fone for Android" and "iLike Android Data Recovery Pro" but both programs instructed me to enable USB Debugging, which is not possible, so the both also: FAILED
Despite this being my first post, I have scoured the forums here in addition to every other forum and webpage regarding this issue as well... There just isn't much about this phone except negative reviews, and I have come to the conclusion that on this particular model phone, I am out of options... I have a paperweight... I'm not very familiar with Android... So please correct me if I'm wrong...

Any input?
I'm curious if there are any options at this point, I have been trying to get through to this phone on several computers for the past couple days and it is frustrating me... Any input from the community would be much appreciated...

Mojo2XL, I guess you did not find an answer?

may be this:
*2767*3855# - Think before you give this code. This code is used for factory format. It'll remove all files and settings including the internal memory storage. It'll also reinstall the phone firmware.
I found code in internet, but may be it works? can't check, my "wave" comes to me from USA by post for a few weeks..

Did you happen to get the files the other member posted that was only available for eight days?

Mojo2XL - Sort of.
I saw a youtub video (sorry no link) that says there was a OTA update that changed the phone's firmware that solved all the problems mentioned here. Thing is I have no carrier and cannot find this new firmware, but, I am still hunting....

Hey hold the buttons as follows volume- & power at the exact same time while your phone is off be warned if you phone was preowned you need the goole account originally activeated with that phone if you do not have that then your in the same vote as me i cant remember any of my gmail account info to my wave from when i had it active I have litterally tried every thing to recover the info and i still can't recover it

let me work on this, been trying to master as many FRP bypasses as i can. I don't have the device but a client is in the same boat

I accidentally stumbled upon a something weird. I've managed to make the camera crash to the home screen somehow. I believe this was a result of holding both volume buttons and opening numerous menus while using the camera. My guess is that it overloads it after a certain amount of times and causes it to crash. I've gotten the android UI to crash like this before. I will try to recreate the scenario and update you guys on this. it's on a Kyocera Hydro Wave. Running android 5.0 I believe. Try going wild until the phone starts to lag. eventually stuff will crash and the lock screen may go with it. use this to your advantage and enable USB debugging as quickly as possible because it will reset itself after about 30 seconds. Someone else on YouTube has recently told me that it worked for them. I would look into doing that.

Is there anything a little more realistic possible? Lol, I can see an update available, can't connect to WiFi to update haha. The stuff they lock these phones with anymore i swear

I'm new to this forum, but NOT new to this site . I have visited here on numerous occasions seeking the help that needed . With that being said, I would like to offer a Bonafide, Tried and True way to factory reset the Kyocera Hydrowave . I KNOW that this work's for I have done in on numerous occasions for a friend of mine that works for Metro PCS ....
Step One: Completely power off the phone .
Step Two: Hold the Power AND Volume DOWN Buttons SIMULTANEOUSLY .
Step Three: DO NOT release any buttons, even when you get to the Boot Menu . (Very Important, If you don't do it right, you have to start all over lol ) .
Step Four: Once inside the Boot Menu, ONLY release the Power Button; or the Boot Menu will close and you have to start all over again .
Step Five: Use the Volume Down Button to Highlight the Wipe/Factory Reset Option .
Step Six: Use the Power Button to Select the option .
Step Seven: Watch the bottom of the screen for the progress, and then use the Volume Up Button to restart .
And there you have it . I hope that this helps out SOMEONE out there, because I feel good giving back for the help that I have received on here .
PS.( If you would like for me to post a Video Tutorial on this, can someone please tell me how to post the Video; I guess by me being a Newbie on here, I'm not allowed to do as of yet ) . If Anyone needs to contact me, as I'm not on here very often, my email is [email protected] .

As unrealistic as it may sound it actually works Trust me on this. its similar to the LG attack which... is nothing but entering a long password.
betanews.com/2015/09/16/bypass-the-android-lollipop-lockscreen-by-entering-a-really-long-password
Just give it a go. it already worked for one dude on youtube. it takes a while but it honestly works. If you can get it, update the phone as soon as possible turn the screen timeout off and let it update. when the phone resets the update will install and you will be able to factory reset.
I mean it couldn't hurt. if you're locked out with no factory reset and ADB tools won't work what else can you do?

Options with Motorola Razr M at Red Eye

Hi, first time poster hoping for some help with my first encounter with Red Eye at bootup. I have a stock phone. I don't really care about the phone but my wife really wants the pictures off it. It doesn't have an SD card or cloud backup and the pictures are on internal memory. I am able to get into the boot options (like AP fastboot) but I do not know what the options will do for me exactly. Can I choose an option that may fix the phone but will not wipe the memory? Is there any possiblity a PC can see the phone at the Red Eye screen if I connect with USB(would a certified Verizon data cable help?) Would actually opening the phone and doing some sort of mod get me any closer to retrieving pictures? I am a complete novice at this kind of thing and only have experience with PC hardware and software and the like.

none of those options will be of any direct help, however fastboot may be used to try and fix it later.
first,
- do you know what caused it to become like this?
- is it bootloader unlocked? if you dont know what that is, there will be some dialogue on the fastboot screen. status code=0 locked or similar.
- do you know what version it was on? if you dont know, did you always update when available? would likely mean latest version.
- do you have a windows pc available, with a usb 2 port, and a cable to connect the phone to it?
edit,
ultimately, this is where we are headed, if you want to take a look at it. specifically the "rsd flasher". i was going to go another route, but this is probably a more direct option.
the rsd flasher will take you to another site, and is made by samuri. im not real familiar with his tool, but know its good. just will save me time in having you tear the fxz apart and flash certain things.
**note, im not sure if this phone was made for multiple carriers, this will only be relevant when getting the correct fxz file. samuri will know more about this than i would.

Not exactly sure what happen to the phone. My wife tells me one minute it was charged at 26% and working fine, the next moment it was 'dead'.
It is locked with a status of 0
My Wife says if the phone had automated updates(if stock phone is configured that way) then yes she has all the updates. If updates require manual intervention then it's probably not updated.
Yes, I have a Windows PC with 2 USB ports and a generic data cable that fits the phone.
I'm looking at the post you linked too now... Thanks again for your help!

no problem
its likely your phone is fully updated, but since we arent 100% sure, its going to be best to go with the most current file. reason being, because you are locked, you can only flash = or forward. if you try to flash back, it will either not work, or bootloop. usually not work.
it would probably be best if you continued this in @SamuriHL's thread for the rsd flasher. he is very helpful, will likely be able to quickly point you to the most current file, and will be able to answer any questions about the tool where i wouldnt.

New Verizon Ellipsis 10 Tablet

I purchased the new Verizon Ellipsis 10 in late November. I believe the tablet was released for sale in mid November. My question is can it be rooted? I see the Ellipsis 7 and 8 can rooted. Wondering if anyone would be working on this or because it from Verizon no one cares. I can't find the tablet mentioned on any search that I do. I Have been checking daily to see if the device will have development on it. Thanks in advance for any information.

In the same boat. Need some help you smart tech guys out there. How can I root my Ellipsis 10?

I have the same tablet, and I do not think it could be rooted, at least not in the near future. The tablet comes encrypted (which I am not too happy about....I just noticed it) and cannot be decrypted, even if you do a factory reset. It runs fine as it is, but would be greatly enhanced if it could be decrypted. I also think there are very few devs on this forum that really care a lot about this tablet, so you may not see too much work being done on it.

Same here, just picked one up. Really hoping that there will be a root for this at some point soon. Someone please help us all out!

wish I would have saved the 50$ now, and got the Samsung tablet for free... it's OK, the biggest problem for me is the audio output being too quiet. all the "volume booster's" on the play store have been jenky, to say the least. if anyone has suggestions of a "good, volume booster", or work around, please let me know. thank you for you time.

Oh, No! Sadness!

qtair7 firmware files
https: / / " www dropbox com " /s/f8ye7yw24mjqiva/IR7-20C59.7z?dl=0
just fix the text when u enter in address bar (-""'s,+.'s)

so i downloaded the IR7-20C59..7z package from the software upgrade/repair tool from verizon... I extracted the files and sent the boot.img to my tablet (qtair7) and used magisk manager to patch the boot.img then I used ubuntu to adb pull the magisk-patched-boot.img and modded it using abootimg and changed a few things from default.prop.. ro.secure=0 ro.debuggable=1 and drm.service.enabled=false .. (just saying im an amateur android enthusiast with little experience. ive played with image kitchens and compiled a kernel and ported a rom for the samsung on5 indie variant to have sound on my smg550t1. worked but all google services and apps crash constantly.. but anyways) i dont really know what im doing just saying this is what i did. repacked magisk-patched-boot-new.img then i sent the adb reboot fastboot command to my tablet and it fastboot flashing unlock , fastboot flashing unlock boot, fastboot flash boot magisk-patched-boot-new.img. fastboot continue, fastboot reboot.. the tablet boots and is rooted with magisk.. now i installed busybox to sbin. i have done this 2 times. im not sure if its the busybox or the magisk, but when i reboot following the above steps i get the verizon splash screen and in the bottom righthand corner of the screen it says modified. then boots to recovery. and now can only boot to recovery. now i have the upgrade/repair tool .iso on usb flashdrive that i use to repair my device from this state. which sometimes is a pita.. i have to continually attempt to repair sometimes it takes 2 days.. before it finally works.. i dont know why.. but it boots from fastboot the first time fine. and would like to know how to stop the soft bricking of my device or how i can obtain a twrp.img for this device QTAIR7.. please help ive been working on rooting my tablet for over a year. and feel that i am very close . thanx

Anyone interested in the system.img or any other partitions.. the Dropbox file is only the recovery flash files. I think. I know I couldn't edit system.img from the file with any kitchen but the system.img I dd'd from my device can be edited with kitchen. It's is 3.7gb so in not going to post unless someone can do something with them

Please share some info on the file you posted,..

Hello, THANK YOU!! This is the most progress I have made in months! I don't know what it is, what it offers, or what to do with it yet, but it is a step!
Could you maybe say what it is, what it will do (how it helps..) and what to do with it?
My Verizon Ellipsis 10 (qtair7), even after wiping the cache, even after doing a factory reset, (even after 'disabling' all but FEW APPS!) JUST SPONTANEOUSLY REBOOTS every time i try to do anything, I try to watch a video it is fine for 5 minutes or an hour then I push volume up or touch the screen and suddenly it reboots, totally random, Clearing the cache gets it to works for a while but it always does it again it has NEVER been usable really,.. It pops up some screen often like"Google Play Services have stopped' something like that,.. Will this help with any of that? Make it more,. stable?
I wish I could just do ANYThING simple to make it better I just use it for video playback,.
THANK YOU!

I have the same tab with the same issues. Rebooting, random cut out and full on reboot. Just before it became target practice I decided to take it apart, just because that's what I do when I'm bored and my ADHD is taking over. I looked up the tab on youtube to see if there was any vids of how to get it apart and found a guy that said he fixed the with the tablet that no one could figure out. Meh I was like ok I'll give him a couple seconds checked it out. He found that all connections, screws holding boards down, and power were all loose. Once he went through all of that it had fixed the issues. So I tried it and damn, everything from screws holding boards down to power feeds were all loose, really bad loose. Got mine working good now. Haven't had issues since. Now if I can get it rooted I'll be good. And I suspect the loose connections would also potentially cause the battery to go bad from excessive amperage draw and charge in short time, over time.

A/B slot boot failure

Hello, I'm Andrea & Im pretty new & a bit nervous to attempt some of these steps. But I very much need some help please.
I have the Moto G Stylus XT2043-4 {2020, I think} through Metro PCS, we've got 3 of these identical phones. However 1 of them is NOT BOOTING UP Correctly. {Using chat with Motorola rescue assistant, they stated: Phone has A/B Slot boot failure, & it is in AP Fastboot Flash Mode (Secure) & only way to fix is to Completely Reset & Start From Scratch.
You see this is My Daddy's phone, who Passed Away on March 6th... & I Desperately Don't Want To Completely WIPE ANYTHING as in User Info/Data if at all possible. So I'm turning here in hopes of assistance to SAVE My Daddy's Stuff that's on his phone.
I have read and attempted the advice/info in some of the threads here & I frankly get a little confused and a bit more nervous when it comes to things here {commands/input correctly} BUT I HAVE TO TRY. Also I am UNABLE To Do Anything as far as Switching USB Connection Type, Debugging, or Enable ADB, from the phone screen or when connected to pc. I feel like I literally need baby steps & entirely walked through this process PLEASE???
I'll post a couple pics of what screen says currently as it attempts to power up, hopeful this will help anyone willing to help me here.
Thank you for reading this longa** post & any attempts to assist me are very greatly appreciated, as I just can't bear to Ruin the last of my Daddy's pics & things from his phine, it is literally the only thing my son & I have left of my Daddy...
Feel free to message me if needed if any possiblity to help.

Unfortunately, I don't think there is any way to get data off of the phone.
The only thing that might be possible, is if he backed up the photos with google photos, and he signed in with another device like a PC.
You could use the PC to access the photos.

Thank you for your info & thought; sd_shadow...
However, my Daddy was 80 years Young & barely able to use this device & had never laid a finger on any other type of system, computer, etc... I tried to show him how to use a tablet once as his TV remote went out & hid TV had an app to utilize in replacement until the company dould bring him another TV remote once the weekend had ended but he wasn't too comfortable with that so I had to scurry and figure out how to reprogram his scrambled TV remote quickly or else he'd planned to stay on the same annoying TV channel all weekend... Infomercials & all...
thank you anyways, I'm holding into hope there's gotta be someone out here in techi~land here who can give some help... Sure,y someone somewhere.... Thank you very much though... Have a positive evening...

I think if you remember his pin or pattern you would be able to flash and use TWRP to access and backup his data on an external SD card and then reflash the rom on the phone and then restore his data back.

[Help Needed] My Shield K1 has been hacked

Hello there,
First of all i have to warn you that i am a kind of a complete newbie about most things you are talking about in this forum. So please, be indulgent.
Also, i'm french, so english is not my mother tongue but, i'll do my best, i promise
I have knowledge in computing but not very much on tablets, phones, etc...
Here's what have happened to me.
Some months ago, i was looking at my tablet (Nvidia shield K1) when suddently it litteraly comes alive without me doing anything.
As i've some computing knowledge it was obvious that someone else was controling the tablet.
So i swith it off using the turn off button. Then i swith off all my network (router and modem), switch back on the tablet and disconnected it from the network. Then i turn back on the network.
The tablet was not anymore linked to the network.
So i start searching trying to figure out what was the problem.
But, as i said my knowledge with these devices is not very good.
This is were my memories are not really accurate as this happened to me a few months ago.
I first decide to ask some help to some people with a much better knowlegde than mine. I gave them the tablet but, they gave it back to me saying that there was no problem. They even upgraded the OS from Android 6 to Android 8 by downloading the update.
So i thought my problems were over but, in fact, they were not.
When i get back my tablet i tried to go again on the internet and didn't succed.
Once i have entered the password for my network, the network appears to be registred but i can't log on it..
So i started to search again for the cause of the problem, after a few hours, i found on the SD card 2 files that weren't here the last time i took a look.
These two files were named :
- Cryptokey
- Systemcrypto
Can't remember their extension....
So, from this point, i knew the solution of the problem was out of my reach as there was probably somewhere inside the tablet some corrupted datas.
This is where i definitely made a big mistake.
First i made a hard reset of the tablet with no results.
Second i have formated the SD card where two files were saved...
Now, i own a tablet with which i can't connect to the internet at home. But, i m quite sure that if i want to connect to another network than mine, it will work. As the guy to whom i asked help first succed to connect to his network and do the update to Android 8.
So, if anyone has an idea of what could i have to do to get back a working tablet, i would appreciate.
Many thanks for reading.
Have a nice day.

Listen I’m not like really good when it come to hacking or anything but I do know that in order to hack android you either need to A, be tricked somehow into downloading and installing some malicious apk or B, someone needs to have physical possession of your device for a short time. Anyone who knows more please correct me if I’m wrong. I think some of those apps for hacking android can survive a factory reset also. But your problem sounds different than just that. It won’t connect to a WiFi network? Try a different network is what I would think to do first.

Hi
I also dont think your device got hacked like @messymatthew already told either you need to install a malicious apk yourself or someone did it with physical access.
But your main problem atm is that you cant connect to your wifi at home which leads me to the question which android 8 rom you have installed right now ?
Or is it the last official oem 5.4 rom which is android 7. In this case its maybe a problem with the PMF function of your Router.
If thats not the case you have two options:
You install the factory recovery image you can find here :
Tablet Recovery images
For this you need to download the right image for your tablet (LTE, K1)
Then follow this instructions :
Instructions - Adb needed
Or you install a Custom Recovery like TWRP you find here :
TWRP - Custom Recovery - Adb and OEM Unlock needed
After this you can install a custom recovery like LineageOS.
Maybe you interested in my unofficial version of the last official 15.1 (android 8.1) which should fit your needs if you want use it as a normal Tablet with monthly security updates.
Scavenger87 - Unofficial LineageOS 15.1

Hello,
Sorry for late reply.
Many thanks to both of you.
EDIT : Forgot to tell you that you are right, my tablet works with Android 7 not 8.
I have tried to connect straight to my modem (so not runnig through my router) and i succeed.
So it seems you are right there is a problem with my new router ASUS GT-AX 11000.
I'm gonna try the solution you are suggesting to me and will keep you posted.

Hello,
@Scavenger87 Many thanks for the help you provide.
You were right, it was the PMF function settings that were blocking my tablet to join the network.
Now, everything is working smoothly
Wish you a very nice day.
