Cannot install Android 7.1 (Jiayu S3 MT6752) - JiaYu S3 Questions & Answers

Hello,
I tried to install the new Nougat rom for jiayu S3, but it was unsuccessful. Phone got soft bricked, but I recovered it with a twrp backup.
My OS is android 4.4.4, and TRWP is 2.8. After installing the new rom , an installation error appeared and phone did not work.
I wonder it it's due to twrp 2.8, but I can't install twrp 3 (S3_h560_TWRP_3.0.2-0). There was an installation error with flashify...
The question is: can I install 7.0 from 4.4? Is it an Android problem, a TWRP issue, or just my clumsiness?
Thank you!

in short:
To go from 4.4.4 to Nougat you need to go via LP RC5 via flashify using firmware upgrade.
This is because the partition layout is different from KK to LP onwards.
Then you can flash Nougat using TWRP (which will be version 3)

Thank you very much for your answer.
Please forgive me for my ignorance but, which LP ROM should I download? Can I install it via flashify, via TWRP 2.8, o flash?
Thank you again!

You can not use Flashify, you have to do it using Flashtools (with a PC) to go from KK to LP. Download LP 5.1.1 RC 5 from MAD.

thanks to correct me, I thought Flashtools was meant

Well, I'm in trouble now... I installed successfully 5.1 in my S3, but when updated twrp 2.8 to 3.0, it did not work, so I can't install Nougat...
Now I have no twrp, and no root. How can I root to install twrp? I can't install superSU neither....
I'm sorry if it has been already answered but I can't find it.
Thanks a lot

I re-installed LP with Flash tools and everything worked right. (In twrp , it says 2.8 version, instead of 3.0, though).
Now I installed Nougat, and everything is ok.
Thank you for your excellent job!

[Q] What is the correct way to install TWRP on the LG G2 in 2015?

Hello,
sometimes I am reading that some users are installing TWRP via AutoRec.
But sometimes I am also reading that some users install Bump!ed versions of TWRP by simply flashing it directly via Flashify for example.
Are there any advantages/disadvantages comparing those methods?
Or would both give the same results?
What is currently considered the best way to install TWRP on the LG G2 when TWRP has not been installed yet?
Regards

It depends on the roms you will be using, if you're going to use a bumped ROM then using the latest stock base and flashing twrp though flashify is the cleanest method, but if the ROM you're using isn't bumped you need the jelly bean bootloader and thus should use autorec. Note that you can install bumped ROMs on the jelly bean bootloader but you CAN NOT install non bumped ROMs on the kitkat bootloader. If you are using a bumped setup and flash a non bumped ROM, it will boot loop. If you don't have a BUMPED ROM still on your storage, you will need to factory reset through download mode or fastboot (whichever you have, some flashable bootstacks purposefully break download mode to enable fastboot. I personally prefer download mode, if I can't get to an adb prompt I'd rather just flash a kdz).

Hey wq.
I very recently installed AutoRec on my D802, which has the latest 4.4.2 KK. It works flawlessly, and I recommend it. I believe the .apk installs TWRP 2.7.0.0, which has worked for me very well, and I have installed at least 15 different ROMs with it so far.
Hello,
thank you very much for your fast and detailed answers.
So, let's assume someone uses AutoRec to install TWRP for the first time on a LG G2, which only installs an old version of TWRP (version 2.7.0.0).
Which TWRP version should one then use to update to the latest version of TWRP?
Would you use the blastagator version from over there:
http://forum.xda-developers.com/lg-g2/development/twrp-twrp-2-8-0-0-kernel-f2fs-tools-t2898705
Or would you use the official version from over there:
http://teamw.in/project/twrp2/197
And how would you install it?
By simply booting into TWRP 2.7.0.0 (provided by AutoRec) and then from there flashing the latest TWRP zip file?

I wanted to flash cloudy rom which is bumped.
So i straight away used flashify to flash bumped recovery and then flashed the rom..
No autorec needed.
I flashed blastgator's twrp with thermal control.

Some mess with bootstack and rom change

Hi guys, I've buy the lg g2 d802 just yesterday.
I really want to try miui v7.
So I've downgrade lollipop to kk trough kdz and everything goes fine. now starts the problems.
I cannot find a good tool to root and I use a one click root + twrp that root the phone fine but when it ask me to reboot to download mode, it stuck at finding new port.
but beside that the phone was rooted (i've check that with root checker).
Then I really don't find any tool or guide to install TWRP recovery, and so I have to install autorec for KitKat. that is the only tool that works for me (twrp manager doesn't work).
So I install with twrp miui v7 gtbluesky.
But many apps don't work, such as camera.
Somewhere I've read that autorec for kitkat downgrade the bootloader to JB and miui needs KK bootloader, maybe is this the problem?
can you advice me a good tool for root and install twrp on G2? So I can have KK bootstack and install miui?
thank you a lot in advance and sorry for noob question

1. if you on KK use towelroot.
2.use autoreck for KK to install twrp.
3.update twrp with blastagator thermal 2.8.7.3 when installing do a reboot into recovery to boo into new twrp.

Can't install TWRP higher than 3.0.2.0 & Update to Nougat

Hello, i was using Skydragon 5.1.1 and it started to become slow, got optimizing apps everytime i restarted the phone, and wanted to flash to LineageOS
Figured I`d update TWRP to latest version, so I got that from their site, version 3.1.1-0 and when I wanted to boot to recovery it would become stuck at the bootscreen. Same thing with any other version over 3.0.2-0.
Used FirstAid to revert to older version of TWRP, and managed to install 3.0.2-0 again and boot to recovery normally.
With this version it seems i cannot install LineageOS because it gives an error.
How do I go about installing Nougat ? Thanks !
First u should install the 3.6.0 Firmware then try install Nougat

I have the same problem. Have you found a solution yet?

TWRP installed, but unable to boot into rom

Hello,
I've installed twrp on my lg g2 802. Using twrp i tried to install lineageos, but on reboot the screen remains black. I see the monitor on but nothing happens. I have to force the reboot. I can still go into recovery but i don't understand where is the problem.
I already tried to wipe everything, and i installed latest nightly of lineageos (no gapps).
Da you have an idea?
I have this same exact problem. I hope a solution is out there!
i installed from a kitkat. Maybe this can be a problem? Should i install lineage from a lollipop?
Flash this
https://forum.xda-developers.com/lg-g2/development/boot-g2-hybrid-bootstacks-t3183219
I got LineageOS to work!
It was a long grind of reading various posts on here and looking up other info on google, but I finally got my phone to run LineageOS.
The three things that I think are key are:
Making sure your phone is starting off with kitkat. I wasn't able to root my phone with lollipop. Stumproot, towelroot, and ioroot all didn't work. Once I downgraded to kitkat, I rooted successfully with ioroot.
After getting TWRP, updating it to 3.1.0. I had to first get an older version and then flash 3.1.0
Change the bootloader to kitkat if it isn't on it already. I used Bootloader Changer.

Yes u need lp bootstacks. Or you can simply get to the stock lollipop using flashtool and then flash lineage os
Thank you for support. Now it works

Help on how to root my j500m

The problem is this:
I want to root my j500m with magisk via twrp but I would like to know if I can root with my version of android 5.1.1 if there is no problem, or I have to upgrade to 6.0.1 to do the process?
Another thing, that when I install the twrp on my device with android 5.1.1 loads everything well but at the time of powering it clears the operating system of the phone and does not turn on completely, it only stays in the samsung logo and I have to flash the rom of stock to solve it but the recovery returns to stock. The version of the recovery that was installed was 3.0.0-0. I would like to know if it is because I am doing it with android lollipop and I should do it in marshmallow or no matter what version of android you have. Thank you.
use this twrp.and first install Magik apk and flash lastest magisk. zip https://forum.xda-developers.com/galaxy-j5/development/recovery-recovery-pro-galaxy-j5-2015-t3728264
And there's no need to update to Android 6 for root
Thanks, but now I have another problem, I just wrote it in the last message of the forum, if you could help me.
Your twrp version is old 3.0.0.0
download this version 3.1.1.1 official
https://eu.dl.twrp.me/j5lte/twrp-3.1.1-1-j5lte.img.tar
and flash use odin.
Thanks friend, I have updated to marshmallow and I have installed the recovery 3.2.1-1 with aroma support, and I have rooted with magisk, now everything is fine.
