Has anyone had a problem getting your micro sd card to be recognized by the zmax?

To begin with I was getting the unsupported file system error.

Thought maybe I just had a corrupted card.

Bought a new 16gig card yesterday. Zmax will not even recognize it. Tried reformatting it on my pc, no dice.

I'm assuming it's a hardware issue, but if someone has a suggestion I'd be grateful.

And on that note, thanks so much to everyone who has been sharing info, developing, testing, and posting about root for the zmax.

I had given up after the old thread became such rubbish. Was using an lg g2 on CM12. And still I missed my zmax.

Came back to it and decided to check in on xda. To my great surprise, (after about 100 pages of catching up), you guys had found root!

Anyways thanks. I won't name names because I know I'll leave someone integral out, but you guys are great.

Omfg. Please oh please make an AOKP ROM. xD
[ZTE ZMAX Guides, News, & Discussion] fire3element:
My first Zmax was really good, but had some issues with the build quality. The back cover of the phone started squeaking on DAY 2!!! of having it. Was not even using the phone, just testing and plugging into the computer a few times.

It was pretty bad after 3 days, and pretty much felt like a well used device after that.

Had to get a replacement after an issue with the first one. My new ZMax feels really solid. Hope it does not start squeaking like the last one.

The screen on my new one is pretty bad. The backlight is very yellow, and all of the colors are washed out. It was also an earlier build date.

Maybe they had some issues with the earlier batches. Dont know

Just thought I would add this so others can be on the look out. The phone is pretty cheap though, so cant really complain too much I guess.

We can barely even make CM ROMs yet. It'll be a while before we can go that custom.
[ZTE ZMAX Guides, News, & Discussion] biledigger:
OK. Time for a factory test demo. An explanation rather.

*ahem* When CPU kits are created for example. A 2.1 GHz CPU chip. They run a series of tests and find out that it either runs unstable or crashes due to not processing properly. Now they create a kernel that limits its max capabilities with a lockdown that forces it to run at 1.9 GHz. They run more tests and find out that it runs processes with a high stability, but however, it runs too hot and ends up giving out or causing a kernel panic due to overheating. Now.... They create a newer kernel that locks the max CPU speed down to 1.7 GHz. They run more tests and find it to be completely stable with little to no overheating at all. They decide to write a complete system kernel for your device that has the CPU locked at 1.7 GHz and send it out as a retail device that you so happen to have bought.

Now!!! You have to ask your self. I have a ZTE Zmax Z970 device.

What exactly was the original test clock for this device?

Keep in mind that the GPU works in the same manner. This is where we normally get the ability to create a so called "overclocked" kernel. When in fact you are reinstating the factory test speeds back to the CPU.

You will experience power fluctuations, kernel panics, software issues and so forth.

The reason it crashes is because they built one single raw kernel and never adjusted it to properly work with these high end speeds. It is also so they can later release it in another device with a better built kernel that supports these higher end speeds and give it a different name for sales revenue. A money pyramid for electronics so to say.

Just build a better kernel with proper coding to give a higher support system to the higher end CPU speeds and you should be good to go. I used to help mod the 2012 nexus 7 and the huawei mercury. You just need time and patience to get the results that you so hope for. All I can say is good luck and godspeed
[ZTE ZMAX Guides, News, & Discussion] tech_yeet:
I have seen phones like the huawei ascend mate 2 run the Quad core snapdragon 400 at 1.6Ghz so I know that would not kill it, as for the GPU however that's a different story I do not know about that....

Z999LP-A-LTE
[ZTE ZMAX Guides, News, & Discussion] biledigger:
The GPU is usually emulatedbfrom the CPU itself. Look up how the PC Intel GMA graphics chipsets work. It will give you a perfect explanation of how a GPU is emulated off of a CPU chip. It causes it to run hotter which is also what you have to work with as well. You have to find a good frequency for both of them that is balanced.

Sorry. I forgot to add. OK some of the devices have an actual dedicated GPU apart from the CPU. 2012 nexus 7 for example had a mobile nvidia GPU chip. I apologize for not including this. Now I feel like a jackass. Just look up whether or not the adreno chip that we have is either emulated from our CPU or whether it is a separate dedicated chip. If it is indeed apart of the CPU and being emulated. Be wary of over clocking it. It will cause additional heating build up by forcing the CPU to pump out more power to ovrerclock itself which in return will cause more heat buildup on the CPU itself. Like I said. Find a good higher end frequency for both of them which won't cause massive over heating on the CPU itself. My old huawei mercury m886 was oc'ed to 1.9 GHz and hit a temp of 137 degrees. I could actually burn my fingers with it. And it had no thermal monitor so it had no emergency temp shutdown. So you also need to be careful of that as well.

Make your own emergency temp warning app if needed. Or just pay close attention to it.

But in all hopes. Just hope like hell our devices have a separate dedicated GPU chip. BTW the huawei mercury m886 had an adreno 220 GPU. It is emulated from the CPU. Let's just hope over the years they got smart and separated them into separated dedicated chips.

...the wtf mode

Hello fellow ZMaxers ^^

So yesterday I was uninstalling or trying to uninstall the T-Mobile apps,when poof...my phone rebooted into the "wtf mode" as it wouldn't go past the T-Mobile screen but It would vibrate as I pressed "Vol up" I tried several times to boot into Android by holding Vol up+Pwr to boot with r/w permissions but the phone wouldn't boot.So then I discovered the "wtf mode" as I pressed Vol up while in the T-Mobike screen ,the phone would vibrate once,if I pressed the second time it would vibrate once,and the third time it would vibrate twice and then boot to android but no r/w permissions...so the question is what's this weird boot mode?Maybe this could help when someone runs into the same problem
[ZTE ZMAX Guides, News, & Discussion] biledigger:
That.... Is horrible. I'm very sorry for you man. One question however. What app were you uninstalling when the reboot occurred? People would have more knowledge of which apps to be careful with if you can report your personal experiences.
[ZTE ZMAX Guides, News, & Discussion] LowPro:
...after the third "Vol up" while on T-Mobile screen it booted and I even replicated the "wtf mode" when I tried to remove the same app, the app was "T-Mobile TV" then I rebooted with "su" and "reboot recovery" in terminal emulator and everything went back to normal, just had to run the xposed framework update because it asked me to...so maybe those vibrations meant something...cache wipe maybe or something like that... :P
[ZTE ZMAX Guides, News, & Discussion] biledigger:
The vibrations from hard keys upon a bad boot up are usually a sign of unsigned input. As in nothing was assigned action wise to those keys from the boot firmware. You're in luck that your system worked after reboot. I'm glad you recovered and are up and operational. BTW. When your system rebooted. It could have been caused by a kernel panic due to an app being watched by a custom firmware setup. An example would be an LG phone. I have dealt with a couple of LG phones that were rootable and moddable. But as soon as you edit, mod or remove LG or the phones main proprietary retailers apps the phone reboots and upon boot up reports "security breach" and just stays at that screen. Stupid anti mod boot loader. But I am glad you recovered from it mate. BTW. If at all possible. Get that butternoob ROM installed. Since he already rebuilt it and is installable. That would be your best route. Especially since it is updated and you can remove all of the carrier junkware from it since I believe he said it was the MetroPCS version if I remember right. I already stripped mine. I only have the visual voicemail left on my stock ROM and all apps updated and moved into the ROM sector.
[ZTE ZMAX Guides, News, & Discussion] Telyx:
It's especially puzzling in light of the fact that the Saygus V2 has its own forum already and not one phone has been delivered yet, and with all the ZMAXes already in our hands AND root, some development, etc., here we sit.
[ZTE ZMAX Guides, News, & Discussion] LowPro:
I've managed to remove the stock apps with Root Uninstaller and avoiding the reboot to the "wtf mode" by sliding my finger on the screen while the process was running.So I'm going to leave it as is for now, maybe when Lollipop or CM12* is available for the ZMAX I'll flash it ;)

Thanks once more to all of you who made this possible ^^

performance boost tip.

For those of you that want a decently pleasing performance boost out of your rooted device. Set your kernel to a 300 mgz minimum and 1.19 GHz max frequency with "ondemand" for your CPU and set your GPU to performance mode so that it permanently stays maxxed out. The GPU we have doesn't kick in to its max frequency normally until we hit a constant 1.19 GHz frequency usage on 2 cores for at the least of the timing of 30 seconds which means we hardly ever get to use our 400 mgz core clock frequency on our devices unless we are running hard core gaming coded for usage on dual core or a higher amount of cores. And even then. It has to stay at a constant max cpu load for 30 seconds which we all know in the testing field that its almost impossible to do that unless you toss something at it that will force it to run that way without any fluctuations. Or put your CPU govener in performance mode which will do it. But that would be a complete battery drainer. Just figured I would toss that out there guys.

End result.

Put your CPU low end frequency to 300 MHz and put your GPU govener to performance mode.

You still get deep sleep with these settings BTW.

I have yet to get viper to work... Im still trying though. Edit got viper working. It's working.. I just tried it on my phone speaker. While I could definitely tell a difference with each setting I changed, it I'd say it's only about 5% louder through the phone speaker. I'm about to try with my Sony Bluetooth headphones, and I'll update this post accordingly on the difference in those in wired mode and Bluetooth mode. HOLY CRAP... Mix viper with poweramp, and it's INCREDIBLE. Well, to be fair, I have Sony MDR-XB950BT headphones... They have lowered them to $200 on the Sony website... However in Bluetooth mode or wired mode, I can no longer have my volume up to max... Just can't.. Too loud... And I listen to my music loud, or so I thought, lol

About the app that tech yet recommended. Yes. And no.

Yes - fully beneficial open source app with a massive selection for control. Plus you can implement it into your ROM sector for a smoother setup.

No - if you don't know what your doing you can screw your device up. Make a nand.

---------- Post added at 01:16 AM ---------- Previous post was at 01:08 AM ----------

You have full R/W capabilities inside of twrp. If you happen to decide to go with in phone full R/W capabilities you can end up with an acme deluxe if you are not careful. Your best bet is to stick with twrp and root privileges until we get a fully functional setup. A lot of apps run without R/W capabilities to the /system. If you need something in your /system modded. Just do it by hand. It is a lot safer that way anyway.

He can try extracting viper4android and moving it to the system/app like I have did many of times via TWPR see what you have to did is, boot in to TWPR the hit mount then check the system file go go back and hit advanced then go to file manger then find a file called emmc then find the apk tap it then move it to the system/app folder...

Don't forget to uninstall tmp root after you flash twrp recovery, using kinguser.APK, and then uninstall all three apk's, this is were the kids who get tmp root are failing, you have to uninstall root, not the APK first the APK won't let you uninstall it until you unroot it, but after you have installed twrp so you can boot into recovery to flash SuperSU inside twrp recovery
