Hello
I recently purchased a Ramos X10F on an impulse buy on a trip to the PP last month. I had been waiting longer than a year for an 8" 4:3 device that was not Apple with expandable memory and this one just made me succumb. Also I fell for the false data in marketing it as a cortex A9 and I thought a quad core A9 should be faster than my dual core A9 in the n7000. Actually it is a A5 or A7 (device details in cpuz mention some A7 blah).
The device has great potential to be an ipad mini killer (at $165) as the hardware fit and finish is very good, the screen is IPS and it weighs only 360 grams. I can hold it in one had lying in bed without tiring myself. However performance is marred by the stock android 4.1.1. Intially I thought it was slow nand flash as when I enabled cpu stats, the nand-rw-flash process appeared to be the top process for a longish time, each time it stalled. However I later discovered, the device is very laggy when Wifi is on while actual WiFi throughput is very good - I get almost full speed 16mbs in the speedtest.net results. Unfortunately even with entropy seeder and a deadline or noop scheduler, the lagginess is only partially improved. Also the old linux/android decision of using input to randomize and seed the entropy is only good for desktops not servers or touchpads. I have to tap a few times to get a app screen to respond inexplicably and suddenly and it shows that the OS was waiting on input. The device is best for streaming as typically once the app is opened I never have a problem with lag a it is typically 15 to 30 mins of viewing before switching apps. Otherwise the poor performance means a task that should take normal time (like reading news in the morning for 15 mins) takes more than twice the time as I have to struggle with the slow app launches and screen loading mostly. But if Wifi is switched off and content is cached, everything is smooth and much better. Battery life is decent with display brightness set around or below 10% typically.
So my recommendation for a new buyer is - dont buy until a custom ROM is made available. Dont fall for the x10pro video on the utube yet. Real world performance is not the same. Once the smoothness of the 4.4.x is acheived it will be a killer product. (It is not a weak cpu either, it is responsive and smooth with wifi off. Although the chip does not support out-of-order execution)
I would like to upgrade the android from its 4.1.1 to a 4.4.x version. Also this version is vulnerable to heartbleed and the openssl bug that came after that in June 2014. The omnirom 4.4.3 on my n7000 is really smooth and I am hoping somebody will develop a custom rom for this device.
But I dont see a custom ROM or CWM for this anywhere. I installed a CWM recovery for another ATM7029 device (yarvik) and it boots, but I forgot about the display driver compatibility and I can no longer view the menu in recovery mode. Otherwise rooted it and running ok.
The specifications of the device are as follows:

What do I need to submit for a developer to build a custom rom for this device? Some kind of dump? Also need a recovery manager with the right display driver. Either TWRP or CWM.
I hope a developer will volunteer.
Thanks

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.

Hi there, I'm wondering how to root my Zoji Z7. I have tried all OneClickRoot apps from XDA and none working for me . Please help
GPS does not work when phone is charging
HI,
my GPS works very well when ZOJI Z7 is on the battery. When phone is charging (on the motorcycle), sattelites are immediately lost and GPS is useless. Does anybody else have simmilar problem with GPS during charging?? I have tried all possible ways of charging (wall charger, power bank, car USB charger, motorcycle charger), but the result is always same - GPS is useless (signal is lost). I have used APPs: maps.me, waze, HERE, mapy.cz, google maps. When phone is charged, navigation apps are lost and not usable.
my video:
I can not add link to youtube, so find it on youtube. Video is called "HOMTOM ZOJI Z7: bad GPS experience ("
Thanks for your help,
ludek
Hello,
The other day it went out, I guess because the battery runs out, and since then it does not work.
It does not react when plugging in the charger, the only "life" sample is sometimes a small vibration when unplugging the charger by holding down the power button.
SOLVED
https://4pda.ru/forum/index.php?showtopic=825309&st=80 POST Nº 90
1) Connect the phone to the charging and simultaneously press the power button for 10 seconds, then Disconnect the phone from charging and reconnect it to charging, it usually turns on in this way;
Or
2) press the power button for about 40 seconds, and insert the charging cable to charge it for more than half an hour, then you need to enter the recovery mode (the volume button "+" and the phone's power button at the same time - you need to come in to restart!

Dont like ZOJI, not good
Rooten and GPS of HOMTOM Zoji Z7
Hi
Has anyone already rooted his Zoji Z7? GPS is super bad! How to contact the manufacturer?
Thanks for your help.
This phone has two recorerys.
One in Chinese: turning it on with a vol-button at the same time as power-on. To restart use the option below.
Another one in English: button vol + at the same time as power on, you will get a small menu that you move with vol + and apply with vol-.
This is the one you can change by TWRP. The other, Chinese, remains.
If you put TWRP and try to do factori reset from the android system will not work again, you can only enter the recorvery and you will have to flash again from the computer with flashtool.

First I installed TWRP, I made backup. When trying to restore the nvram and nvdata after installing andrid 7 nougat does not boot the android. The fixed start screen remains.
Possible Virus in Zoji Z7 ROM 1.1.2 0525
There seems to be a Adserving virus in Turbo Battery app. Test using Kaspersky. Check for presence - settings/apps/show system.
Look for Turbo Battery. I wonder if any other Z7 owners can check for this
In the forum 4pda talk about this, the viruses.
https://4pda.ru/forum/index.php?showtopic=825309&st=480
I put Android 7 nougat, much more fluid, and clean virus, without apps and annoying advertisements
Zoji virus
Thanks lots of good info there. Z7 is a good bit of kit lcd usable outdoors, OTG, waterproofish etc. I have tried for a week or so to get Zoji support to admit to a virus! Where does the Android 7 come from is it leaked from Zoji? btw just disable Turbo Battery to stop the ads at 1.1.2.
Use *#*#12306#*#* to reset IMEI
or use
QuickShortCutMaker activities/engineer mode and select IMEI icon.

On your Android 7 I cannot see any way to control the upper left indicator red/green/blue LED.
Not sure if GPS works properly at this level ( has the does not work while charging error). Hints appreciated. Cheers
I too have just received my Z7 and have found the battery to drain way to quickly on closure inspection I found the aforementioned Turbo Battery app which has indeed got adware buried inside, nasty trick hey. Has anyone rooted this device as yet ? if so details would be fantastic and much appreciated
Disable MI keyboard and Turbo battery (both are system apps) After that the phone is really excellent good battery life can read display in sunlight (just about) etc. Have contacted Zoji and Homtom on this and found them useless. They have said they might fix it but don't live in any hope.

Hi, i have a z7 who is broken, after flashtool the flash is stopped. Now i can't flash it again, is there a solution?
Windows don't recognize the device anymore. thanks
Hello
Needs expert advice in choosing a device. Namely, I work as a driver (TAXI and Uber), I have a standard radio in my car (DVD 800 - OPEL) and a wonderful Galaxy S5 Neo phone, which thanks to you has Android 10 and root. But it's already a few years old, it also has a broken screen and a very swollen battery. That's why my wife decided to buy me a tablet for work and play. However, the Galaxy will get a new battery for now. But I don't want to spend too much money.
My request is that you help choose a "better model".
I will only mention that the Uber (1) and TAXI (2) apps need at least to work;
* Android 5.0 (1), Android 6.0 (2)
* GPS - (the more accurate the better), A-GPS, GLONASS
* Internet connection (* This application typically uses 2 GB of data per month. Using navigation may shorten your phone's battery life - Uber info)
* 2 GB RAM
* SimCard slot (I checked Lenova Tab2 A7-10F on a tablet and it worked but it was about a year ago - the tablet died.)
In addition, the tablet is to be used in the car as a temporary multimedia source, so it should have a "3.5 jack", bluetooth, Wi-Fi.
A SimCard slot would also be nice, especially LTE 4G.
Here are my suggestions:
(I live in Poland, so prices will be in PLN)
My budget: PLN 420
allegro.pl/oferta/tablet-10-1cali-android-9-0-8gb-128gb-dual-sim-9522094216?fromVariant=9522134933

allegro.pl/oferta/tablet-s13-10-1cali-andr-10-0-wifi-8-128gb-dualsim-9484996186
I hesitate between the first and the third.
Thanks
