[Q] Custom ROM for Ramos X10F anyone?

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:

Battery: 4000mAh

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

[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:
MAKE TERACOM
MODEL TZ200
OS Android ICS 4.0.4
CPU 3 core 1.2 ghz cortex A8
RAM 512 MB DDRIII
DISPLAY 7" 800*480 5 POINT TOUCH

There is no system update option in my tab settings. But i notice a service called rkupdate service running in the background.I havent connected the tab to internet else.There is another tablet BSNL PENTA IS701c with the same specs of my tab. Idownloaded a rom for the penta tablet and tried to flash it via CWM but it failed. Can any one provide me a rom for the tablet with above specs. It can be .zip or .img file.Please help!!!!!!!!!!

UNEXPECTED SHUTDOWN UMI ROME MTK6753 Octa Core 64Bit 4G

Hello
I have UMI ROME MTK6753 Octa Core 64Bit 4G
From about 1 week, the phone turns off suddenly even if the battery level is above 90 % .
Even not hold a charge even if it is connected to the charger .
I bought the phone in January.
I Wind operator .
For six months there have been no problems .
Suggestions ?
Stefano

Same here.

Which firmware are you on? I have two Umi Rome phones, one on 3.03 and another on 3.04, and neither have this issue. I suggest you go to the umidigi forum to get the latest version (currently 3.05)

I ordered a new battery. Now it works fine...I hope for almost a year...

Hi.
Same here, bought a new one!!!
Firmware 3.01.
Now i have another UMI Rome problem!!!
Everything i touch on the display, do another process, menu or letter!!!
Made a factory reset and stays the same shi...
Thanks.

I had the same problem with my UMI Rome. Noticed the charge dropping very quickly, or the phone randomly shutting down and then after re-enabling the smartphone it was like 40%. Also, battery got a little swollen and I got a new one. It's working but the battery life / time on is not as good as was the stock one (even though it looks 1:1 the same).
I am on Firmware 3.04, updated via UMI software.
I also have a problem with the touchscreen, it's like its getting inaccurate, I have to press way lower than I actually need (like press below a big button to actually click on it). I have to look into recalibration.
On another note (sorry for a bit of an offtopic), anyone tried unrooting / magisk / phh's su to successfully play Pokemon GO? I haven't updated since their 0.35 version because I heard of the root checks and now that they enforced 0.39, I'm looking for a way to play it...
I am really unhappy with the UMI Rome, they promissed way more than they delivered. Battery life since the beginning wasn't satisfactory, now it's super bad. Screen isn't amoled, and there are multitouch and generally touch issues... the metal parts get scratched very easily, the plastic case I got is lowering my wifi reception really bad... Everything seems wrong.

What can i do with a phone that doesn't completely work

I have an old Vodafone 895N, pretty good phone, fast, big, cheap but the signal doesn't work like is supposed to do.
Sometimes it let me do phone calls, messages (with a delay) but sometimes doesn't do them at all,
The phone is 60 USD, but i can't sell it with this problem and i can't use it either because the calls are why the phones are made ..
8 GB, 1 GB RAM, Quad-core 1.2 GHz Cortex-A53, Android 5.0.2
I have tried to root it, to install the stock firmware again but none of it worked.
I'm sure there is a hardware problem that might be fixed but at a cost that is more then 50% of the phone itself FOR SURE ..
maybe i'll open it myself and see what's inside ..
anyway ..
What would you do with a phone like this ?

About all it would be good for is a MP3 player/radio or it could be used as a security camera in home/office or a backup camera in a vehicle if linked with a other device such as a tablet or another phone.

Does WLAN work alright? you can turn your device into an android media center.

Also I have the same problem

Does over using a phone cause significant hardware degradation?

I have a LYF Wind 7 with a 1.3 GhZ Quad core snapdragon 210 and 2 GB RAM. The phone was snappy and slick when I got it. But now after 1.5 years, it has become so laggy that it's become impossible to use it. Whenever I open dialler, it takes 5-10 seconds. The back button responds 10 seconds later while inside WhatsApp or any other app. Even after factory reset, it runs fast for a day, but returns to being laggy. The firmware is the latest version. Tried force stopping all apps with greenify but nothing works. Internal memory is 3 GB free.
Now my confession is, I have overused the phone. I have often used the phone's hotspot with Jio as my primary data connection. Now is it possible that a phone's hardware can degrade this way? I'm planning to buy the Zenfone Max Pro M1 but will it get laggy like this phone if I overuse it by using it as hotspot?
