I havent flashed any zips yet...

I think there is a communication error. i can boot to twrp, but nothing else (including ftm mode). After i installed the first version of the twrp for zmax, i used twrp to install supersu. I was successfully rooted and could boot to android or twrp or ftm mode at will. I wanted to start new and went to "wipe", selected "advanced wipe", and checked "davlik cache" "data" "internal storage" "cache" "system" "microsd card", then swiped right to wipe (as i have done on dozens of different phones). Now I am unable to do anything but boot to twrp. Twrp cannot mount /data or /system. I have not installed any zips, or img's of any kind because they all fail due to not being able to mount data or system. Ive tried dozens of times to no avail. This is where im at and would love for someone to help me out. What do i do next? Can you lead the way? Thank you all again for your help.

I have placed recovery images on the sd card but twrp doesnt see them to install them. By that i mean i boot into twrp, click on "install" and choose external sd (img is stored on there), but the only thing listed is the zip i got off this thread. No img. Is there a different way to install the recovery? Adb is out of the question, i cant get ino ftm mode (volume down)(after about 45 seconds the screen goes black and the indicator light flashes red and green for another minute or so)

Twrp says "No OS Installed! Are you sure you wish to reboot?".
[ZTE ZMAX Guides, News, & Discussion] Masterchief87:
Why would not having ftm mean that adb is out of the question when you have twrp? Twrp is 100000000% better than ftm because twrp gives you root adb shell which ftm does not. Also, why would you need to flash a recovery image when twrp is already installed?

If you power off the phone and then turn it back on with the power button only, what happens?
[ZTE ZMAX Guides, News, & Discussion] iancc86:
It stays on the "powered by android" screen. Thats it until it dies. How do i flash a rom or anything if twrp cannot mount data or system? What should my next step be?
[ZTE ZMAX Guides, News, & Discussion] Masterchief87:
Did you ever update twrp to the 2nd version?

Can you access twrp by holding power and volume up?

Well its been a ride guys, woke up this morning and my ZMAX's backlight stopped working. The gyroscope had already been acting dumb (figured it was because of the test build of super butter I was running), but I woke up this morning and the phone's backlight was shot. Took it to my friend who's a tech repairman and he confirmed what I thought. He's a real bud though, he had an Xperia Z1s that he said he'd give me since he didn't use it anymore. Thanks for the wild ride guys, if I can continue superbutter I would love to, but I don't have a second ZMAX to test on. I'm really excited to see what this community cooks up, you guys are awesome :)

Ftm is provided through the boot image which is why he doesn't have it

---------- Post added at 07:27 PM ---------- Previous post was at 07:22 PM ----------

You need to try to get a system image to flash.... Your going to have to find someone with a clean system image for your phone... Make sure your TWRP is in the recovery partition by having someone send you a recovery img... Open your terminal through TWRP.... and try to put the two in place... You may also wanna see about a boot image from your particular model.... Try to get them as stock as possible

Once you have the image files pm me and I'll help you from there

I have a feeling I will be joining you too very soon mate. My gyroscope has been acting quirky. Such as the screen spinning out of whack. Rotating on its own. And my screen is starting to yellow over as well as developed a ton of bad pixels

My mistake. Wtf ever it is that controls portrait/landscape control and whichever direction your phone is pointing in GPS. Not sure wtf it is. Or how to calibrate it.

[ZTE ZMAX Guides, News, & Discussion] fire3element:
Wonder if these problems are limited to phones with an older build date.

I know the first one I had seemed fine. Screen was fine, but the body sqeaked.

Second one I got had a terrible screen. Very yellow and dark. No doubt I would have had issues if I had kept that one.

The second one I had was an earlier built model.
[ZTE ZMAX Guides, News, & Discussion] DroidisLINUX:
Yea probably bad hardware, it is mAde in China after all, My phone has been acting up, so I went back to normal boot, on boot, recovery with twrp. Might be in my head seems to be better though

Can you take the MicroSD card out and put it in another phone or connect it to your computer via an adapter?

You may try to load a zip that way and then put it back in your phone and try to flash.
[ZTE ZMAX Guides, News, & Discussion] biledigger:
stuck

Well. The accelerometer in my phone is fine. Just needs to be calibrated for the stock ROM. I flashed cm 12.1 and it was fully calibrated. Went back to stock. Needs to be calibrated. I have no idea about how to do so though.

This is another mod that works great.

If any of you are like me you reeeeeally hate how low the volume on the phone speaker is, this is a mod to help remedy that and raise the max volume on the phone.

https://youtu.be/kyCxhpo5PHE

Note: There is also a setting at the very top of the page that says rx1 rx2 rx3 and rx4 with a value of 84, make sure to set that at the same volume as you set the other setting. I put mine at 92 and it's a HUGE difference.

Just remember playing anything on the phone speaker at super loud volume may blow the speaker so be smart with you volume control.

Or if you don't want to risk anything make sure you have r/w privileges and copy my XML file to the /system/etc folder and reboot should be good to go.

just did this and now no sound is coming out of my phones speakers. No music or anything. Put the original file back (thought ahead and made a backup of the original) and no dice still no sound coming out of my device.. Im restoring from a twrp backup i made from a while back so I'll report back if that fixes it.. if not then I dont know what to do.

EDIT: Sweet success sound is back after restoring from a TWRP backup.. a little frustrated that I had to go through the trouble to fix this but oh well.

[ZTE ZMAX Guides, News, & Discussion] DarkFireBrah:
My post about this is literally a couple posts up lol. Anyways the way I fixed it was went into twrp and restored from a backup I made a while back and got my sound back. Doing that or flashing another rom like butternoob might be the only way to fix this.

I never did update twrp. I didn't have a chance to before this happened. Is there a way to update twrp from within twrp?
[ZTE ZMAX Guides, News, & Discussion] Vyrus69:
You have to use the twrp and boot.IMG zip that masterchief made and posted over at android forums. Then you need to go back and restore twrp. I have no issues with it.

If someone on 4.4.2 wants to send me there mixer path .XML file I'll be glad to make the changes and upload the file for you guys.

[ZTE ZMAX Guides, News, & Discussion] DarkFireBrah:
I am also on metro 4.4.4. Doesn't seem this is just a problem with the zmax in the comments of the video others have this problem as well.
[ZTE ZMAX Guides, News, & Discussion] Masterchief87:
OK you can use one of my restore zips which will update twrp to the 2nd version and make sure that it is on the correct partition. If you are on 4.4.2 you need the T-Mobile one or if you are on 4.4.4 you'll need the MetroPCS one.

LINK TO MY THREAD

Edit: Hroark13 just updated twrp to 2.8.6.0 today so it looks like I have to update all four of my zips again.
[ZTE ZMAX Guides, News, & Discussion] Vyrus69:
Another thing that may be different, on my phone I've also deleted the useless Dolby files on my phone.

Maybe try that with my xml file to see.

And if that doesn't work, instead restoring a backup image, restore the original file and in TWRP clear up your cache and davlik and that should do the trick as well.

The other issue I thnk that might be the problem is make sure the permissions are set correctly too. rw-r--r--

Others have been able to do this trick and it works, don't know why on your phone it isn't.
[ZTE ZMAX Guides, News, & Discussion] Masterchief87:
Do you have the MetroPCS zmax or the T-Mobile version?
[ZTE ZMAX Guides, News, & Discussion] DarkFireBrah:
Permissions are set correctly. Could be the Dolby digital thing that made my phone act up. I would like the higher volume but at this point it may be too much trouble honestly. I might try manually editing the file by following the video tutorial later today after I get off work.
[ZTE ZMAX Guides, News, & Discussion] Cyconumnum:
i did the editing manually without deleting anything...works like a charm....after reboot ..since i have ADHD ..i jumped because i got sidetracked and forgot why i rebooted....lol...funny

i gotta try this with BUTTERNOOB ....if it fixes stuff without all kinds of installing of audio mods ..i can just install bass booster ...dolby seemed allready offline....BUT,as i said before...that mighta been my idiocy and installed some thing incorrectly..................more than likely
[ZTE ZMAX Guides, News, & Discussion] DarkFireBrah:
If you dont mind me asking what did you edit in the file? I might try this manually to see if it works.

[ZTE ZMAX Guides, News, & Discussion] Cyconumnum:
I read Vyrus's post... Went to the YouTube video he linked.. And in the details of the video I found a link to a written tutorial...

But, the tutorial has the wrong RX number listed for the ZMAX.

Vyrus has it correctly listed....

But the tutorial has two other settings listed...

I put those at 20

The RX's I set to 90 to be safe first

http://www.davebennett.tv/android-boost-speaker-volume/

<path name="speaker">

is correct in the tutorial

but,

<ctl name="RX7 Digital Volume" value="88"/>

has the wrong RX number listed for the ZMAX in the tutorial picture/example

BUT, if you find <path name="speaker"> in your .xml file the RX will still say Digital Volume" value="88"/>

just a heads up...i'm not trying to steal anyone's thunder...

that's what i found out when i went hunting and pecking in mine.....i used SManager.apk to search and edit the mixer_paths.xml file because that's what i'm used to ....it's a habit from the F6 sitar editing...blah blah blah

and i have yet to uninstall dolby because everytime i uninstall a app that came with my phone that not bloatware i end up with errors and have to do something in the line of flashing a recovery......so...so far ..dolby has not had it's head on the block

i still give MAJOR PROPS to Vyrus69 for leading me in the right direction
[ZTE ZMAX Guides, News, & Discussion] DarkFireBrah:
Yeah the rx number was different and dealing with the zmax I didn't wanna charge ahead all gung ho and mess something up without getting clarification first. All good now I bumped the speaker volume up but haven't tested just how loud it is now. Pretty excited to try it later.

*****WARNING: THE XML FILE BELOW WAS PULLED FROM THE METRO 4.4.4 VERSION OF THE PHONE, I'M NOT SURE IF THIS WILL WORK ON THE 4.4.2 TMO VERSION, IF IT DOES FOR ANYONE, LET ME KNOW******​

For anyone who's not on the Android Forums, here's the tutorial for our phones:

If any of you are like me you reeeeeally hate how low the volume on the phone speaker is, this is a mod to help remedy that and raise the max volume on the phone.

STEPS:

1. MAKE SURE YOU HAVE FULL R/W ABILITY

2. NAVIGATE TO /SYSTEM/ETC AND LOCATE THE MIXER_PATHS.XML FILE.

3. COPY THE ORIGINAL AND SAVE ON YOUR SD CARD.

4. DOWNLOAD THE MODIFIED MIXER_PATHS.XML FILE HERE OR IF YOU'D LIKE TO DO IT MANUALLY SCROLL DOWN FOR INSTRUCTIONS.

5. PASTE THE XML FILE IN THE SAME /SYSTEM/ETC FOLDER AND FIX PERMISSIONS TO RW-R--R--

6. GO TO /VENDOR/APP AND DELETE ALL DOLBY FILES.

7. REBOOT PHONE AND YOU SHOULD NOTICE MUCH LOUDER VOLUME OUT OF YOUR SPEAKER!

8. ENJOY!​

MANUAL CHANGE:

1. GO TO /SYSTEM/ETC AND LOCATION MIXER_PATHS.XML

2. OPEN FILE USING A TEXT EDITOR OR DOWNLOAD AN XML EDITOR FROM THE PLAY STORE.

3. SCROLL DOWN CLOSE TO THE BOTTOM AND LOOK FOR <PATH NAME="SPEAKER">

4. BELOW IT YOU WILL SEE THIS LINE:

<ctl name="RX3 Digital Volume" value="84" />

5. CHANGE VALUE FROM "84" TO WHATEVER YOU WANT, I RECOMMEND 90 - 95.

6. SCROLL TO THE VERY TOP OF THE SCRIPT AND FIND:

<ctl name="RX1 Digital Volume" value="84" />

<ctl name="RX2 Digital Volume" value="84" />

<ctl name="RX3 Digital Volume" value="84" />

<ctl name="RX4 Digital Volume" value="84" />

7. CHANGE ALL OF THESE VALUES TO THE SAME VALUE YOU SET AT BELOW.

8. SAVE CHANGES AND REBOOT.

9. ENJOY!
