I'm with ya on it. I've been messing with this thing for days now. I'm not giving up.
[Android Q&A, Help & Troubleshooting] joshworx:
I think I've figured it out. As my z820 is now up and running as normal.

What I did was fairly simple. As I noticed yesterday, after a few boot cycles, the device would boot into the OS GUI, saying that "Android is upgrading," well, I figured I'd let it sit there and bootloop overnight, as I also noticed, it upgraded itself further and further each time. So when I got up this morning, the device had booted into its stock rom.

So what you have to do is:

Boot into stock Recovery (3e)

Wipe data/Factory Reset

Wipe Cache

After you're done with that, it'll take some patience. Just let it sit and do its thing either overnight, or check back every few hours to see if it has booted fully.

This is the only method I have found so far to fix bootlooping, if anyone finds a faster method, please post here for everyone's convenience.

I have had my T-Mobile ZTE Z820 rooted for about a week now using King Root 4.9.2. I didn't install the "software enhancement" update, disabled the notifications, and just renamed the file with a .bak extension in case it is needed later. Ok my problem is I want to change to Super SU and uninstall King Root / User. I have run the script that is all over the net and XDA (you have to change the command in terminal emulator because sdcard is not a valid storage name for this phone. Anyways I did post on the Remove King Root install Super SU thread and had no luck with finding the reason I can't change my SU. Has anyone had luck on this device with the script or using SuperSU Me? I have heard bootloop stories about SuperSU me so idk... Thanks to anyone who could help on this. I'm still on 5.1 and Build number is B18
[Android Q&A, Help & Troubleshooting] plttwht:
The script worked for me on the Metropcs Z820. You may have to use a file manager like root browser or root explorer to determine the actual name of your phone storage. It maybe named sdcard0 but that's something you would have to check on the T-Mobile z820.

Itried that but it just bootloops...no gui or nothing. sometimes it even locks up when playing the tmobile jingle and stays that way for about 30 seconds or so the reboots and continues the cycle. I have the source code for the phone and would like to try to make a recovery and rom for this phone but all guides are outdate i guess...i cant get anything to work and dont know much about bbqlinux. If someone could guide me i got the time and a good computer to do this on

I found this... http://xdaforums.com/showthread.php?t=1982587 and attempted to use the backup someone posted in this thread. the scatter file is read by the program but i cant get the mediatek VCOM drivers to install. Well it said it did but when i plug the phone up it still says its using MTP USB driver (and its not the right driver) I feel im on the right track to at least flashing the stock ROM but would love if someone could point me in what direction i need to go. As far as I'm concerned this phone is a paperweight now but would like to at least try to learn from this and maybe help others get their phone working again. Lord knows many people have posted stuff on this site that has saved me many times.

UPDATE: I figured out if you hold the volume up button while you plug the phone in it will load the driver but now the program says I need the authinitcation file and i have no idea what that is or where to find it.. Any ideas anyone?

ZTE Bootloop of mass irritation
[Android Q&A, Help & Troubleshooting] Cruise Elroy:
Yeah, SuperSUme will bootloop you. At least the version I had along with the latest version of Kingroot did. Apparently there is NO love between the two devs, and they've basically declared war. I'm not saying Kingroot's devs put my device in a bootloop on purpose, but I do believe that either their "anti-SuperSUme" code or SuperSUme's "anti-Kingroot" code may've accidentally done so... BTW, anyone know what apocalyptical fate befalls anyone who dares to flash a Metro PCS ROM on a T-Mobile Z820? I mean, I'm sure your SIM becomes useless, but what else? I noticed most custom firmware is for the PCS version, and the author is always careful to state "METRO PCS VERSION *ONLY*" in the post... Almost like a nice, big red button that says "DO NOT PRESS..." [emoji48]

The bootloader on this particular phone is locked that's why you get the Authentification Error when trying to flash the scatter file with SP Flashtool. Maybe there is a workaround for this if anyone on this thread knows.

**** Kingroot! Unroot if you have used Kingroot Kingroot blows. Use Kingo root and just install Super SU over Kingo. then use ur file manager to uninstall/delete Kingo stuff. Oh! you need to have Kingo user installed from the market first. Then use one click kingo to root! Then as I stated move Super SU in! That simple. I use to use Kingroot but kingo is the #1 root tool right now. PERIOD!!

SuperSu from KingRoot

I used KingRoot and KingoRoot both pc and android version multiple times and the only one to say im not rooted is Kingo android version, no matter how much i run it.

Anyway I want to know how to get rid of KingRoot's SuperUser so i can use SuperSU because all the root things want that (Primary example is Lucky Patcher)

But in SuperSu it says i need to update the binaries then takes me to a webpage that gives me two update methods.

But i read above that Method 1 (SuperSUme) bricks your phone, which i REALLY dont want to do.

Method 2 makes no sense to me.

Please help

P.S. i dont think im fully rooted. Sometimes nothing will have a problem, other times its "ROOT REQUIRED >:("

EDIT 1: Apparently its Kingo's superuser. same issue tho.

EDIT 2: im also told to update kingo's superuser binary, if thats all i have to do, great. but it makes no sense either. just says reroot
[Android Q&A, Help & Troubleshooting] John Lucas:
Don't mention Lucky Patcher..... You need to flash custom recovery. Which to my knowledge there is none yet. Some use pro v of supersume. I myself don't like it. I've soft bricked on Kingroot using supersume. I prefure Kingo root. I succeeded first try. Trick is (YOU NEED TO HAVE KINGO USER OFF PLAYSTORE INSTALLED) Then click on click kingo root tool. Then you can run supesu over kingoroot 0 issues I promise! But Kingroot has a Su blocker so you can't just run supersu over that. But ya a friend of mine had this device. I went with kingo so he could have supersu. Again I don't think this phone has a recovery, which means no roms, which means you can't just flash supersu zip with a custom ROM to gain su that way. Sorry hope this helps.

Kongo is temp root I'm pretty sure. Meaning root doesn't survive reboots or on/offs.

I rooted a MetroPCS ZTE Z820 using King

o

Root - downloaded directly from their web site. 1 click root, worked fine. It installed its version of SuperUser - now I want to use ChainFire SUPERSU ... I installed SuperSU from the playstore, gave it SU permission using Kingo root superuser - and Chainfire SUPERSU is trying to update binaries, but fails every time.

There seems to be a lot of confusion between KingRoot and King

O

root - and methods seem to vary from root method to root method...?

So the bottom line is: IS IT POSSIBLE TO REPLACE KINGOROOT SUPERUSER WITH CHAINFIRE SUPERSU ?

If anyone can give me some idea?

for the record, I've tried installing ChainFire SuperSU from playstore and letting it try to update binaries which fails... I've tried uninstalling Kingo ROOT before letting SuperSU attempt to update binaries, again fails...

---------- Post added at 09:55 PM ---------- Previous post was at 09:19 PM ----------

Solved it myself... I feel stupid now. I installed SuperSU (chainfire) from playstore, gave it SU permissions in kingoroot superuser, made sure it had permissions.. uninstalled kingo root and its superuser (long press, drag to uninstall) and launched SuperSU (chainfire) and it immediately updated binaries successfully. :) rebooted and supersu is now active and working... verified with AdAway which requested root access via SuperSU and granted it.

Hope that helps someone else...

THANKS EVERYONE.

Hello i dont know if you already had done some thing to your ZTE prior to allow your method but when i try, it just tells me I have no SD card and takes me back to the main recovery options, and when I try it with one in, it takes me to the recovery file manager,

sooooo I tried going to the ''root integrity'' option* hoping it might have an effect. (as my phone started to ''boot loop'' after attempting to install the software update on to my rooted ZTE) but as I entered the option I tried your suggestion of pressing volume down and power button and got a animation of a android man with the two antennas on his head moving, and the message ''Erasing''

I was soooooo excited thinking this would fix the problem but after a while an android man with a red cross (x) appeared with the words ''No command''

pressing the volume up and power button a couple of times took me back to the recovery options main screen with some yellow error messages listed + system check fail message

if anyone wants to try maybe they can figure something out! good luck!

---------- Post added at 08:29 PM ---------- Previous post was at 08:01 PM ----------

Also perhaps there is a pc program or method that can allow us to fix permissions? as whenever I have that optimizing apps screen problem when android is starting on other phones, I just fix permissions in CWM and the optimising apps screen usually fixes/loads

finally is there some way I can remove root and kingroot through a pc/ program as I believe this is the cause for my bootlooping/optimizing apps issue. thank you.
[Android Q&A, Help & Troubleshooting] Techfinder:
hello could you please explain what you did exactly i.e

you flashed the stock rom with ''sp'' tool?

or you flashed the stock rom as a ''sd update'' in stock recovery?

or you flashed the *software update* in ''stock'' recovery?

you flashed the *software update* as a ''update zip'' in recovery?

or you did something other than these things?

my rooted ZTE obsidian* gets stuck in a boot loop at the optimizing apps screen ever since I tried to update the software.

any help would be much appreciated thanks.

It Worked

Just confirming that this worked for me on the MetroPC variant (ZTE Z820), I was a bit skeptic but it worked. It did a series of boot-loops before I got to the setup. I'd say it took about 1 - 2hrs or so. The problem started after accepting the "Software Enhancment" update that later failed which caused the whole mess. I had rooted prior to updating so root might have been the real culprit.
[Android Q&A, Help & Troubleshooting] BlacktRose:
Bootloop

Hi, would you be able to re-upload this file? or send me a link? I'd like to see if it could be used to recreate some conditions. Thank you!

Well, earlier I said this worked, and it did. But me like a fool went ahead and tried replacing KingoRoot's SuperUser with SuperSU, and it went from normal operations to "Android is Upgrading" or was it "Optimizing App 1 - 125" after SuperSU updated the Su binary and I restarted.

Now it's been in a continuous loop sometimes only getting to the company's Boot Animation, other times making it as far as Optimizing App 35+ - 125 before restarting. I knew I should not have taken that update when I saw it, since most updates are just security patches, meant to make customers life a living hell. So much for trusting this company to handle things in good spirit.

I'd like to know why they allowed the update without a basic root/integrity check before updating their customers phone anyways, most likely knowing the update would cause this, and not even having any means of restoring the device to stock without us sending it in. I'm in no position to send the device in anyways, and it would probably cost most than its worth where I am.

Would it be a problem if they sent out a rollback update to fix our problems? Or if not an update to roll back, one removing the conflicting files? To really just leave us hanging is sad, and I'll probably not have much interest in, or recommend anything ZTE as time goes by.

Hey all

This is not meant to be offensive at all to any of the developers. I am just flat out wondering what people think of the TouchFLO option and the Cube option.

Myself, I dont like either "addon". I mean they are nice...but for me I have no need for them...but of course thats just me :)

Keep up the good work developers...my Prophet has gone from frustrating to fricken amazing...all thanks to you people :)
[JAMin, XDA Neo, S200 ROM Development] mr_yellow:
The Cube is a piece of garbage for all I care... It looks cool, but that's it. not functional at all...

TouchFLO is quirky but pretty functional allowing me to scroll without having to grab onto the scroll bars. handy for me since I don't have long nails and it improves one-handed operation.
[JAMin, XDA Neo, S200 ROM Development] gokhanmoral:
yes to touchflo, no to cube

personally, I like touchflo, but just the scrolling part. it is handy for PIE or contact manager.

for the cube, I think it is too much for my prophet.

I do not use fast dialing in the cube, I access them from htc homeplug today plugin. I do not listen to music, watch videos or surf in the pictures folder on my phone neither. I prefer the plain old functionality for comm button.

gullum's new approach for activating the cube is somewhat better in my opinion (swiping nail at the bottom of the screen to activate it). but again, I never use it as I don't need it.

I feel like it is meant just for showing the effects to friends and say "look, my phone can do this and that" and that lasts for just couple of days.
[JAMin, XDA Neo, S200 ROM Development] story:
CUBE is pretty useless if you can't edit the launch.

but I like the QuickDail in CUBE. I would wait for V6 to come out. The CUBE activation is nothing you tried before. It's every effective & hidden if you don't use it.
[JAMin, XDA Neo, S200 ROM Development] gullum:
there is a app to edit launcher :D comin in V6 :)
[JAMin, XDA Neo, S200 ROM Development] maair:
Cube and Touchflo are very useful when they're in HTC Touch.

But with Prophet soft screen , I think I need just only HTC Home and as "Original" as WM6 Rom. :D
[JAMin, XDA Neo, S200 ROM Development] SeniorNoob:
The CUBE

The cube has the same app. launcher as the home plugin. The picture contacts, sms, email, internet, wireless manager, video, pictures, etc. The cool thing about it is that it is hidden away, but at the TOUCH.....of a finger it will appear to access whatever app. you want. This leaves room on the today screen for other applications, or better applications like marsware weatherpanel chameleon version for the weather. You cannot go wrong trying to get your local weather with this app., but everyone is having problems with the htc touch weather app.. I'm glad you brung this topic up because I would like to just use the cube and I think I gave a pretty good opinion, and if anybody can get just the cube to work p m me or make a new thread so everyone can see it. Can't wait.
[JAMin, XDA Neo, S200 ROM Development] petervbeck:

IMHO the cube looks nice but after 2 days you have seen the cool effects and don't use it anymore. the fingerscrolling is cool !

You can just disable it from TODAY
[JAMin, XDA Neo, S200 ROM Development] LordDeath:
i flashed the pdaviet touch rom, looked at the cube and disabled any hardware button assigned to it :cool:

i my opinion it is useless. it is slow and accessing my favorite programs is even without it every easy. so there is no need for it.

but touchflo is a bit different: it is usable in almost every application. scrolling around through the windows folder makes fun now - with resco explorer :)

it is a usefull addition, which works with 3rd party apps: very good!

but i have a question about touchflo, the cube and this htc today plugin: do we need to cook extra roms for them? isn't it possible to create a .cab for every single of these features? storage memory on the devices is limited, and storing some apps which have been disabled since the beginning by the user is just a waste of memory.
[JAMin, XDA Neo, S200 ROM Development] gullum:
Cube has become verry intresting

As most of my beta testers will agree on... the cube coan be usefull finaly and does not have to take the place of any button hard or soft and having the option to asign which programs are activated by the cube is now not a problem any more... and the TouchFlo I can see how anyone can not like it... with touchflo the use of stylus is minimized to writing text and if one uses a good phone pad you could almost trow away the stylus...

just my toughts
[JAMin, XDA Neo, S200 ROM Development] mewwoo:
sounds great Gullum!

I'm looking forward to using your V6 ROM.
[JAMin, XDA Neo, S200 ROM Development] FInixNOver:
Just touchFlo for me(very handy for scrolling in one had operation mode). :D

Since I use SPB Mobile Shell,and PhonePad the using of the stylus is reduced to writing some text and SR.
[JAMin, XDA Neo, S200 ROM Development] dommelstein:
Cube is just the beginning

TouchFlo is great, makes it much easier to control the device with one hand.

The Cube right now looks great, but is not that functional yet.

The cube could somehow become the new today screen, making it even easier to control the device. So the idea behind the cube should be used in other aspects of WM.
[JAMin, XDA Neo, S200 ROM Development] Shark_XXL:
I do not like Touch Flo very much because of several reasons...

I have a question for an alternative:

Would it be possible to change the touch flo function so it is possible to scroll like in Opera mini4? Somehow like "hold and move"

Today I tried the Ipod touch which has nearly the same software as the iPhone will have. Apple also included scrolling in that way....I find it much more comfortable than TouchFlo....

SO anyone an idea?

[JAMin, XDA Neo, S200 ROM Development] kamalneet:
i like both since both could be provided ,so why not use both,it would be more better if cube could have launcher window too inside it.
[JAMin, XDA Neo, S200 ROM Development] littld:
Touchflo

I like the scrolling and I like the look of the cube but just having 6 apps to launch makes it a poor launcher.

Ideally I'd like to see more sides to the cube or 9 icons per page or something. Everyone launches more than 6 apps!

It's good to show off with though!
[JAMin, XDA Neo, S200 ROM Development] l3v5y:
I like the cube, and with customisation it's pretty near perfect. One thing that would be really useful (it it's possible) would be the addition of a comm manager screen on top of the current three to increase it's functionality and allow me to change what my Comm manager button does hardware wise...

The touch scrolling is very very useful because I use an on screen finger friendly phone pad. I now never have to use my stylus (except for resetting).
[JAMin, XDA Neo, S200 ROM Development] aloshka:
I don't use the cube for the fact that customizing the damn launcher stuff is too damn complicated. I think ultimately if someone could develop a cube to be a today screen that would be beyond awesome. So you can create different pages and select different plugins to show on the pages. That way you can use stuff like SPB pocket plus and just do unlimited things with it. It doesn't even have to scroll or anything special like that.
