Hello X20 powered JiaYu S4 expected mid April

Thanks for your reply.

Would love to try the same but I have not been very successful at doing upgrades. Must be me. Do you have somewhere I can get instructions for an oldie to do this. My S3 has been a great phone so if I can improve it would be a bonus. Have tried to communicate with Jai Yu but never get any response. Any help most appreciated.

OK found it. Make sure you follow well and do some background reading. Make sure you install the drivers for mtk, you should easily find it on the net. If you are not part of NeedRom then sign up because that is where you will get most of what you need.http://www.needrom.com/download/rom-xtreme-rom-tf/

After the reading it gets confusing but it all boils down to to this:

1. First of all make a full backup from your data.

2. Install the preloader driver(e.g. All-MTK-USB-Driver-2014.rar).

3. Download and extract flashtool(e.g. Flashtool_20140812(v5.1428.05.000).rar) and the flashtool version of this rom.

4. Start the flash_tool.exe, load the scatter from the rom directory, make you sure all the rows are checked(preloader,lk,boot,recovery, ..etc.)

5. Power off the phone

6. Select the “firmware upgrade” and klick the green Download button.

7. Connect your phone to the computer, if your driver installed correctly, tha flash will start imediatly.

8. Power on your phone. Thats all.

If you are stuck don’t hesitate to ask. Also the flashing tool is funny with win 10 , if you have win 7 it is better :). All the best

well Nolan maybe your knoledge of Mediatek SoC it’s a bit outdated: My MT6795T RedMi Note 2 GPS fix always fiw in few seconds even in cold start, GPU it’s a bit outdated but anyway trounces snapdragon 615/616 competition definitly…and likely MT6797 would smash every Qualcomm SoC but the costly 820

“Low Antutu score” That pretty much sums up your post. I am not a fan of either but Mediatek destroyed Qualcomm last year. Last year was the year of Mediatek. Qualcomm screwed up with the SD615, SD410 and SD810. They were either terrible (410) or suffered from performance issues (615/810). I realize a Qualcomm fanboy as yourself could never see that though, so stick to your random numbers on Antutu.

Your worldwide sales numbers are incredibly flawed. Samsung uses more Qualcomm chips than Exnyos chips. Huawei uses a variety of chips besides its own Kirin chips. Xiaomi and Lenovo use a variety of chips including MTK. But the biggest flaw is you ignored the “others” section which has the largest percentage of sales at 45%. Without knowing what phones are included in the “others” we have no way of knowing. Not to mention those numbers are for only 1 quarter of 2015.

No one is arguing the numbers though, Qualcomm holds the edge having deals with nearly ever manufacturer. We arguing quality of devices. All the sales numbers in the world don’t make up for the fact that the first round of 64bit SoC’s were terrible failures from Qualcomm. Meanwhile the SoC’s from Mediatek were very good.
