[Completed] [Q] need firmware

Hi guys out there! I just registered on XDA forums a couple of days before hoping to get some help to my problem. I bought a cheap tablet last year. It is teracom tz200.Right from the day of buying it, i noticed a wierd thing on it. The battery started to drop 1% for each 10 seconds(100%-99% FOR THE FIRST 10 SECS. AND 99%-98% FOR THE NEXT 10 SECS.) and after some time the tablet would shut down of low battery(0%). I thoght that the problem was with the battery and replaced the battery of the tablet with two mobile phone batteries of 3000Mah (the original battery was too 3000Mah). But after replacing the battery i started to notice something more weird! The battery started to drop 1% for each 8 secs. and would shut down at 0%.But this time i figured out a new thing.After the tablet has shut down, i will leave it for rest for 10min. when i switched on the tablet again(after 10 mins. of rest after shutting down due to low battery)it would switch on and start to drop 1% for 8secs. (as i mentioned before) and shut down again at 0%.Like this i can use it for 10-11 times(SWITCHING ON THE TAB AFTER IT SHUTS DOWN DUE TO LOW BATTERY) each session lasting for about only 13 - 15 mins. I went through many articles online, they said improper calibration of battery(the batterystats.bin file) could cause this.So i rooted it and made my way to the batterystats.bin file, deleted it but of no use, the same condition prevailed even after doing that(I ALSO USED THE BATTERY CALIBRATION APP).So can any one guide me through a way to get my tablet fixed?I rooted it and flashed CWM recovery and i have a rom backup.So i would be pleased if anyone can find a ROM for it so i can flash it to check whether the problem is solved.The details of the tablet are:

I recently brought a cheap android tablet (JLAB PRO-7) from Staples on Black Friday. Has anyone flashed a rom or did anything with this particular tablet?
I tried rooting it even though it came partly rooted and now evey time it is cut off or it reboots it is back to as if it came straight out the box. Do any one have any idea on a fix for this?

Glad someone else is looking to root JLAB also!
I am desperately looking for info on this also. You left out the biggest surprise and annoyance with this low-end tablet...NO ABILITY TO MOVE APPS TO THE SD CARD!!! This thing is running 4.4.2 for Chris sake! After OS install, you only have 5GB internal memory. I put a 32GB card on it in order to shuffle off the app memory hogs and I can't even use it!!! <calming down...>
As a result, I get "insufficient memory available" errors for many programs. And some won't even consider the tablet for install. I know you get what you pay for, but the specs on this thing aren't awful. It just needs a decent OS on it. I tried loading into the bootloader once and almost bricked it. When rebooted, the "JLAB" opening screen came up and just stayed there...forever. I finally had to leave it on overnight to completely run down the battery to get it back from the abyss.
Please, if anyone has this thing and is able to put a decent rooted OS on it, post it here. Thank you!

+1 any headway?

I got one for xmas from a friend... I was able to root it with kingo root tool for windows.
I hope this helps.
Make sure debug mode is on in developers options.
To enable this mode clicking the "build number" a few times in system settings.
It rooted my device but i ran into a few issues. First every time the device does a full restart it makes me do the welcome wizard also
(unsure if my defective or not) my wifi signal becomes extremely weak even though i am sitting next to the router.

Kewlz now that we have root all we need is a custom recovery. Id be willing to test out a recovery if someone wants to make one.

I found out the all these cheap tablets are rebraned the manufactor is trio they also sell tablets under their own name.

For the love of God please make a room for this. It's often rebranded please let us know if it works with some other room.

I also rooted my Pro 7 using KingoRoot and am now facing the issue of a factory reset every time the device restarts or powers off/powers on. Were you, or anyone else able to solve this problem? Thanks!

I did not resolve the issue. I returned the thing and got my money back. There are much better options out there then this cheapo thing.

There are definitely better options but it was free on cyber Monday at tiger direct. It will be a decent tablet for my young son if I'm able to get it sorted.

I agree with you. But logically it's been a year and these China tablets see no dev love. Unless you know the inners of android OS... I wouldn't suggest it because you will be taking on issues like this alone. ebay the Toshiba Thrive. They are really cheap now and run so much better. If i remember right someone made custom kitkat for it. It's really durable and strong perfect for a kid.

It's been several years since I had an android device but I go the same black friday deal and figured that it would be a great ereader (free). Now I need a little more room so I'm trying to root but both kingo and king root failed for me.. Any ideas? I'm on a mac running windows through a VM but I don't think that is the issue.

Your version is obviously newer as this thread was made last Xmas. As I stated these devices have little to no support so finding a working root would be hard. Your computers os shouldn't matter. If you want an easy root return the device and get a name brand device.

[Q] ZTE z797c Quartz

I just bought 2 ZTE Z797C Quartz from Wal-Mart for me and my wife for Christmas. Hers is for Candy Crush, but I have wanted to root this device since before I walked out of the store.
As far as I know from my meager research (that I somehow found time for) there are no " 1 click " methods out there yet for the z797c And, surprisingly enough, not one thread or any mention that i could find on this site. (again, dont have much time to search, I could have missed it)
I think the main thing i want to ask is if there a beginners guide out there for getting Root access to new phones? I have the next couple days off and i want to dive as deep as possible into this phone in this time. I"m not one to shy away from something just cause I have never done it before. And I don't care if i brick this phone.
If you know of anyone that has rooted this phone or if there is a guide you know of please let me know.
thank you for reading, good morning. and if i dont see you, good afternoon, good evening, and goodnight.

I too have this phone and I have looked everywhere for a root also. I don't think it's been out long enough for a root to be made. I hope someone would come up with one soon.

I bought this phone for my girlfriend in November I ran into the same problems I did with my zte unico adb just reboots but I'm also not the most experienced but I have yet to find a one click yet for either... I have a feeling that this might be like the unico where no one finds a method BC its a budget smartphone along with straight talk putting a bunch of locks on it ... But I hope it isn't

I've looked into all kinds of options here.
The bootloader is locked(of course), that's why ADB just reboots straight into the rom, so we can't access fastboot.
They've put a custom recovery on the phone that actually removed the option to flash update.zip... adb does not work in recovery either.
If another dev happens to check this post, perhaps you can point me in the proper direction or tell me what I should work towards for progress
I don't mind researching, I've just turned all of Google's links purple on this one.

ZTE Quartz IS Worth Rooting!
I think we may just have to begin randomly seeking out Developers on here instead of waiting for one of them to find or even stumble upon our rather complex and unique problem with locked bootloader and adb is worthless with fastboot. Why so much security for an economical smartphone?

Temp Root achieved
Achieved temp root via this script.
Be advised that this will only give a adb root, and that we still have no /system access due to r/w restrictions from bootloader..
Thanks go to @jcase and @hroark13
This will give us a bit more freedom in exploration.
Good luck, I'll be working on it as well.

Just for future reference:
The new version of KingRoot (as of 4.5) will successfully temp root this device, for a few minutes or so, giving apps root access as well...

I'm terribly new to the "world" of Root.
What can you do with temp Root permissions? I did actually achieve it, but the apps I uninstalled were right back there when I exited, do I have to uninstall & immediately reboot? Not sure how this all works (yes I am googling "how to root", maybe I need to do "what to do with root"?

Has anyone gained root access for this phone yet.

anything on this root problem yet i have the same problm just temp root that goes away after reboot.

Wife's S6 Received "M" Update Last Week. No issue Until Two Days Ago.

Hello,
My wife's S6 just received Marshmallow last week. We're on Straight Talk service on AT&T's network and everything was working fine up until Wednesday night. First, her phone went from 45% to dead in the span of an hour. Then the next day she had issues with her mobile data where she had no connection. We deleted/reloaded APN settings but that didn't fix it. I have the same service on my Nexus 6p and the same settings and mine works like a champ.
I did notice that her Android OS was consuming 45% of her battery and without any idea how to fix it I went ahead and performed a factory reset, twice. She still has excessive battery drain (70%-40% in 5 minutes), she no longer has mobile data, and her cellular/texts work sporadically; however Android OS is now under control. She now has cellular standby eating up 30% of her battery and app optimization was at 28% (This could have been due to reinstalling all her apps). I would like to say it's a hardware issue but seeing as how multiple people are having some of the same issues I think it's an actual problem with her update.
Is there any way to fix this without going back to Lollipop? If that is my only option where is the best place to find a legit version?
Here are her phone's specs:
Model: SM-G920T
Android Version: 6.0.1
Android Security Patch Level: May 1, 2016
Baseband version: G920TUEU3DPD6
Kernel Version: 3.10.61-7610624
[email protected] #1
Thu Apr 28 19:59:51 KST 2016
Build Number: MMB29K.G920TUEU3DPD6

Look, I'm going to tell you this straight.
Marshmallow has had a lot of problems.
Just scrolling through a few threads reveal most of peoples problems come from after updating to M. My S6 is completely untouched, in fact, the battery life is better.
Google released M way too early without testing it with their lab devices enough. Too many bugs, too many things missing. My best guess is uninstall any apps your wife got recently and if that doesn't work, carry a cheap power bank until Google releases an update.

I was able to downgrade to 5.1.1 and it solved her battery issue, but not her mobile data. I called Samsung and we're going to get it serviced to see if they can fix whatever is wrong. What I find funny/frustrating is that any time a new version of Android is released (and lately apple too) there are always tons of problems with battery life and other issues. You figure they'd get it right one of these days.

I upgraded to M just over 2 weeks ago & my battery life/phone experience is excellent. I was also reluctant to update, but no regrets at all in hindsight. My advise: Watch out for OTA updates - rather download new firmware & use Odin to flash.
Head on over to good ol' Sammobile and download the latest firmware for your carrier and then follow the instructions to flash. Perhaps that might help.

Just wanted to provide an update. We just got the phone back from Samsung. They ended up replacing the motherboard and that fixed the issue with no mobile data. Also, the new motherboard may have fixed the battery drain issue. It's a little too early to tell but battery drain appears normal for now.

Switching android rom on cheap AliExpress phone

Hi. New here. Have learned a lot from this forum about using ADB and playing with my phone a bit.
I bought a cheap 100 and change android off Ali express. They sell smaller sized handsets which seem less common these days on the mainstream market.
The phone boasts good specs online. It has no brand on it or make model number anything. The back pops off old-school like and doesn’t say anything.
when I check the imei on imei.info it comes back to a
Make: I-MOBIL C
model: I-MOBIL DE CV
It’s advertised as an Ip13mini. I think it’s rooted. Comes with developer options turned on. No set up screen it brings you right to the Home Screen. It’s android. But the icon pack are iPhone icons.
it functions poorly. Connects to wifi but play store won’t download apps. Try to sideload app files and there’s an error. Try to debloat with ADB and it says —user 0 unknown or something.
The guy only responds with ‘my phone work normal’
what else. Oh. Even though you can’t do anything with the phone, the battery drains rapidly like, every few seconds it drops a bit.
Can I flash anothe rom onto this thing? The searching I did shows me download instructions for many roms android lineage etc but for specific handsets.
is there a generic stock android or any OS for that matter that I can put into this phone? And where can I find instructions on how to do the flashing?
I have a good laptop to assist me.
I got the 256gb version expecting a semi smooth android experience at least. I’ve had other cheap Chinese phones and some had stellar performance and zero bloat. I’ll attach a pic of the screen with its specs.
hoping to learn something new since I never flashed a custom rom before.
