OK. So I gave the newest build of his ROM a run last night. When my battery hit 4% the phones display went blank and the notification led started alternating between red/green. I did a force hardware shutdown. Afterwards. While powered down. The bootliader reported that it had the incorrect type of battery installed. Please be careful if you run this. I was able to recover from it because I am used to this type of ****. I just don't wanna see people reporting battery incompatibility based bricks. So for the love of god. If you run the cm alpha/beta builds. Leave TWRP installed. Just as a safety precaution in case this happens to you as well.

[ZTE ZMAX Guides, News, & Discussion] biledigger:
That is seriously odd. I had voice on mine. I actually had almost no issues at all on mine. The only problem I had was the whole 4% battery issue when my screen blacked and the notification led alternated from red to green. I even had full audio support. High end decibal levels audio from speaker output. Calling fully worked. Although I wanted ipv4 for my mobile data and it didn't work. Need it for tethering purposes... But however. It was damn near rock solid.

Oh yeah. When I went to unlock my phone. The screen always stayed black for about 4-5 seconds everything's me I turned my screen on to unlock it.

Only problem I am having since going back to stock is my sensors being out of whack.

[ZTE ZMAX Guides, News, & Discussion] Masterchief87:
I am not using any otg adapter cables. I have 3 flash drives that all have the micro USB on one end and regular USB at the other end.

Stick mount will mount your otg flash drive to /sdcard/usbstorage/sda1 by default. Also, worth noting, I have the pro version of stick mount but I only use the free version because when you install the pro key, it will mount /sdcard/DCIM to /sdcard/usbstorage/DCIM and give you annoying toast notifications every time you reboot, along with an ongoing notification in your notification drawer that you can't get rid of.

The free version works perfectly though. The only limitation is that it won't tell you how much free/used space you have on your USB stick.

Only $3.99 for a USB OTG cable at Fry's.
[ZTE ZMAX Guides, News, & Discussion] fire3element:
Or a $1.50 from Dealextreme.

http://www.dx.com/s/usb+otg+cable

(Note: their delivery can take 1-4 weeks)

I highly recommend a 90 degree angled adapter on the micro USB side. Cuts out a great deal of stress if you were to bump the connector while plugged in.

They have angled adapters that face different directions also. Try to get one that will make the cable run across the bottom of the Zmax vs hanging off the side like most angle OTG cables will.

Wrong direction:

There are many many types of OTG cables and styles on DX.

I am not going to go through all of them to find the best ones. Gave you examples above.

Be careful on DX. Not because they are bad, but because they offer so many things for cheap.

You will find yourself browsing their site for hours. Sooooo many goodies to look at.

$1 cable here... $2.50 adapter there .... It all adds up when you finally check out. LoL

[ZTE ZMAX Guides, News, & Discussion] Lesharoturbo:
You cab factory reset if you have root. You can't IF you have the images swapped for R/W. Basically, when you put the recovery image on the system mount point and the system image on the recovery mount point, it will mess up if you try to reset. If your images are om the proper mount points, you should be OK to reset.

zte zmax rooting

Has "ANYONE " actually thought this through , randomly----- perhaps root ( in the traditional way)cant be done because there is already a way to access the r/w system built in but hidden, but its not done in the old root methodology!? maybe , just maybe its as simple as finding the correct way to access to gain read/write access to the system , I guess .... I dunno im just throwing it out there ... maybe someone should try the simple things first. How much more simple could that be... access is there just use the right password???

Perhaps we are looking at the ZTE ZMAX programming all wrong-- does anyone agree with me on this? anyone??????????????????????
[ZTE ZMAX Guides, News, & Discussion] Beerthirty:
Ok so if I factory reset . Which way should I do it
[ZTE ZMAX Guides, News, & Discussion] DroidisLINUX:
I have been saying it since root has been achieved that there is probably a way by editing our boot.IMG, there is about 7 fof the dozen or so files inside the boot.img that all check and mount the system as ro and if you look at them one or two say rw while in recovery

If someone was to change all the

mount system ro,barrier=1

Lines in all files to

mount system rw

Instead and repackage the boot.img we could probably see full read write in regular boot.

I have tried but I can't get the boot.img packaged to the correct offset and be 16 megs. I was using xda's android kitchen

But since then I found another Linux tool that is supposed to be for newer androids made in 2014 that can pull a boot.cnf that should be able to get the correct offsets and size of dead space right, but my device is being worked on so I can't test it yet when I get my new device back I'll let you know if I find anything

[ZTE ZMAX Guides, News, & Discussion] hroark13:
yes they have a way, it is threw recovery, that is how they flash all their updates, they do not need system to be r/w any other time

---------- Post added at 01:50 PM ---------- Previous post was at 01:18 PM ----------

dude I have already told you, you are talking about mounting system ro or r/w not system write protecting, it is different, it is in the boot loader(aboot or LK "Little Kernel"), not the main boot kernel (zImage) or ramdisk, do you think I would not been able to get passed it, if it was the init rc files ?

This is how ZTE implements this system write protection.

When the phone is turned and when the boot loader is loading (this is before the boot kernel). There is code executed that reads the Extended CSD of the mmc card (ext_csd)

https://android.googlesource.com/kernel/lk/+/qcom-dima-8x74-fixes/platform/msm_shared/mmc.c

Line 2567

I am not sure if we can mod the ext_csd or not, I have tried and failed, and there is a lot of info in that csd, but it also has information on any sectors that are to be write protected, this is determined by some params like wp_grp_size and such. Now if the boot loader boots you into regular Android (boot from the "boot" partition" it temporarily write protects those sectors and they can not be changed. If however the boot loader boots you into recovery, the boot loader does not do this.

Now there is code in the kernel zImage that denies permission to mounting or remounting /system as r/w. This is why people get permission denied, when they try to remount /system, same thing it is not called if you booted into recovery

Since we have the source code to the kernel, you can bypass or removed this code if you want and you will not get the permission denied error anymore when you try to re-mount system, and it will look like you have R/W to the /system partition, and you can delete a file and it will disapear, but as soon as you reboot the phone any changes you made will be gone, because you were only modding the buffer, I have it this way in my CM12.1 I think

https://github.com/hroark13/android_kernel_zte_draconis/blob/cm12.1/drivers/mmc/card/block.c

if you look at line 271 and3239

they both says #if 0, it use to say #if 1, but I changed it to bypass the code, I am not sure why I did this, I dont know if we can use it anyway or not

Anyway to get back to my point, unpacking the boot.img, and changing some lines in the init rc files is not gonna get you system r/w

what you want is a bootloader unlock or a way to mod the ext_csd

And consider yourself lucky because ZTE implements this write protection on more than one partition on other phones, like the ZTE Whirl 2 is write protected, on /system boot recovery, basically everything but data and cache, so they can not even flash a custom recovery to get r/w access, or flash boot to recovery to get Android booted with /system r/w

If you dont believe me maybe [MENTION=2376614]jcase[/MENTION] can verify it, he should know all this

The kernel source is driving me nuts,hope this doesn't date me..lol

when they do a function there block delimiters I.E {} are lined up vertically, the way I am used to, but within a function for example they put it on the end of the line before the block of code, its easier for me when they line up vertically instead of mixing the old and new format.. it really messes with me while reading it *SNIFF* .

Ok my question, looking at the code piqued my interest. Could someone point me in the right direction to find the files for the bootloader, if no source so i could disassemble them.

i know a little ASM and i am pretty good with C.

P.S. if anyone has any questions about C PM me, I would be glad to help.

Carrier IQ is installed on on our Z970

In a post on AF, 9h0s7 pointed out that Carrier IQ is active on our devices. http://androidforums.com/threads/carrier-iq.922016/

Big Brother is watching, but we can do something about it. The following is copied from one of my replies to that post:

Using a guide for the LG G3, that was posted on XDA (link, below) I adapted it for the Z970 (MetroPCS version, and it should work on others), and this seems to work.

Using Root Explorer, or ES File Manager with the Root Explorer option enabled:

Navigate to the /system/priv-app folder and rename the following files, by adding .bak to the end of the filename:

IQ_OOB.apk --> IQ_OOB.apk.bak

IQ-tmobile.apk --> IQ-tmobile.apk.bak

IQToggle.apk --> IQToggle.apk.bak

Navigate to the /data/data folder and rename the following folders, by adding .bak to the end of their names:

com.carrieriq.tmobile --> com.carrieriq.tmobile.bak

com.carrieriq.tmobile.IQOOB --> com.carrieriq.tmobile.IQOOB.bak

com.carrieriq.tmobile.IQToggle --> com.carrieriq.tmobile.IQToggle.bak

Navigate to the /system/lib/ folder and rename the following folders, by adding .bak to the end of the filename:

libiq_service_tmobile_2.2.so --> libiq_service_tmobile_2.2.so.bak

By simply renaming the files, if it breaks anything, you can just reverse the process, and all is well. Alternatively if you are feeling frisky, just delete them, at your own risk. I will probably delete them, later, once I am sure nothing is broken,

Enjoy, and let me know if you find anything I missed.
