I recently dug out my Smart Ultra 6 and wanted to remove CM and switch to Lineage with Magisk. However I found a lot of dead links and issues trying to do so.

The main issue I had was a bootloop on LineageOS 14, which the recommended fix for was to install a rooted 6.0.1 ROM first - however all links were dead.

Therefore I've compiled some links and basic steps which could be useful to anyone else who stumbles across this forum looking for help

Directory Link Here

0. (optional - if you are using a custom ROM) Getting back to stock
	- Use your current recovery to flash (Smart_Ultra_5.1.1_recovery [STOCK].zip)
	- Reboot into recovery to run (Smart_Ultra_5.1.1_update [STOCK].zip)
	- Reboot to system and update OTA to latest marshmallow 6.0.1

1. TWRP on Marshmallow
	- Extract 'Smart_Ultra_TWRP_recovery[3.0.2.0] (qfil)' to C:\TWRP
	- Install MiFlash (Ignore QFIL/qualcomm flash image loader)
	- Load in the C:\TWRP directory
	- Plug your phone in via USB and hold power and volume down to boot into Qualcomm flash mode
	- Keep hitting refresh until your device shows up, then never touch it again
	- hit flash, it'll probably fail
	- keep rebooting your phone (holding power and volume down) and hitting flash, eventually it'll take

2. Backup
	- Reboot back into recovery (now TWRP)
	- Take a NAND backup

You can now proceed to install lineageOS/gapps/magisk via TWRP.

Andrew

I found some interesting bugs: one is that if you have low battery, about to self power off, and you switch on the torch, it stays on even after the phones is powered off, and you can't turn it off whatsoever, except plugging in the charger and switch on the phone again I guess, but I didn't try it. The matter is that if you let the torch on to let the battery discharge completely, and the light goes off, when you charge it again and switch on the phone you can't switch on the torch anymore, even tho the system claims is on, it doesn't beam any light from the flash led. The only way to "reset" this status is to open the phone, removing the back cover, unscrew 3 screws that hold a tiny bar and manually disconnect the battery (most rightside connector) and then reconnect it. Not even holding the power button helps.

Another bug is that if you turn on the phone, and then, without putting it on stand-by, check with some kind of cpu monitoring app the cpu cores activity, the less powerful cores of the A53 are awake and running. If you put the phone in stand by and then re-awake it up, they are always on sleep or "disconnected" or similar status. Even tho it seems that this doesn't affect performance, so it seems that they doesn't show correct running status but still works.

Last but the most important: the phone THROTTLES at room temperature!!! If you try a cpu intensive app, the cores throttles at 800 MHz or less, and if it heats more it goes down even to 200 MHz stuttering everything! I don't know if it gots bad thermal spread design or is it a thermal sensor bug, since in system monitor apps it shows temperature above 49~50 in idle while room temp is 20 to 23 °C and over 67-68 while running full calculations!

Can anybody confirm or else suggest me some solutions to these issues? Thanks.

Can save the phone or i'm going for a new one?

Thank you.

I remembered that Nutsda was working on an Oreo rom but I don't think that there has been any update since last year.

Would it actually be possible to have an oreo rom which has treble enabled so you can install newer android versions without too much trouble?

I'm not a heavy smartphone user so my SU6 has been my daily driver for nearly 4 years but it would be awesome to get some up to date software.

Thanks for reading

I try to download ADB, CDC, MTK... My problem is that they seem to install, but in my devices menu, I have the dreaded triangle and exclamation mark and my pc (Win7 and Win10) do not see the phone. I have what appears to be a good working copy of Media Tek SP Flash Tool v5.1644.00 but it appears to not regognise anything due to driver issues.

Am I doing something wrong or just looking in the wrong place? This is getting so frustrating and time consuming that I am ready to bundle up these 5 phones and bin them.

Any assistance would be greatly appreciated.

I did a quick search to find any similar options and the best suggestions I could find seemed bizarre.

They were something like the following:

1. Disable adaptive brightness.

2. Disable hardware overlays in developer options.

I turned off adaptive brightness for a few seconds but decided to turn it back on. I don't think I have experienced the issue since then but then again it could come back. It did only happen randomly and occasionally.

UPDATE: Without trying to fix it I managed to replicate this effect but only happens sometimes in the YouTube app when switching portrait to landscape when rotating the phone.

My Marshmallow Smart Ultra 6 is very slow, battery life is bad and I can't use AUX cables. I thought I'd do a factory reset but I thought I might as well downgrade to Lollipop. I see there are bits and pieces of info on the topic scattered around the forum but no thread specifically about that. I would like to ask for help with this and I'll collate all info I've gathered here so if anyone wants to do the same in the future, they have what to use as a guide.

1. I have downloaded the UK 5.1.1 VDF-995NB01-UK09b stock ROM & recovery from the Vodafone Smart Ultra 6 stock ROMs, OTAs, and recoveries thread.

2. My phone has 6.0.1 VDF-995NB02-UK10d stock ROM with stock recovery, therefore I need to install the stock recovery for B01-UK09b

^ This is where I am stuck. I can see you can install a stock recovery with TWRP, but I need root to install TWRP, but I can't get root because I'm on stock 6.0.1.

How do I install TWRP or how do I downgrade my stock recovery so I can install the old stock UK 5.1.1 ?

Any help would be much appreciated! :)

(am really pleased there's a modaco thread on this great phone, have been tempted back on the slippery slope though!)

So, my phone had recovery twrp and the lastest lineage rom.

suddenly it gives an error and i reboot it. then it is stuck in boot loop.

after that using the twrp recovery i do a factory reset. still boot loop.

i try to flash diferent roms but now it says an error.. cant format. no data, no cache. Unable to mout data or cache or whatever.

now i only can go to twrp...

link for TWRP for 5.1.1 http://www.modaco.com/forums/topic/375554-recovery-twrp-2870/?page=5 thanks again konstat

Been looking at the forum but now I have an issue I thought I better make a post, so hello :)

I installed the latest OTA update and now when I try to run the Kingroot app it appears to get stuck at verifying root status.

I have tried clearing the cache and uninstalling and reinstalling the app but to no avail.

Does anyone have any suggestions to what could make this app work again?

Thanks

Ross

All ZTE support links and site is down and I have been looking for 2 hours without finding it!

Allow me to clarify: BOTH these "Three" UK sims work perfectly in all my other phones. I've never used a voda sim in su6 (they never gave me one) but I don't want to mess about, so would someone be able to shed some light upon this error, please?

Both sims are fully activated and I've cleaned the gold contacts with contact cleaner very gently... NADA!

Any thoughts would be gratefully listened to, thanks :)

TRY IT AT YOUR OWN RISK I AM NOT RESPONSIBLE,FIRST DO A NANDROID ,PLEASE REPORT ANY BUG

What is this rom?

This MIUI V7 rom is a port of coolpad f2 rom,adapted to VSU6 

so maybe in some apps or in usb conection names the phone as coolpad

kernel is a "hibrid" kernel(stock,MIUI from coolpad)so it can be unestable

   I am bored with rom miu7

I was downloading some images, when the screen got stuck for a bit, flashed some lines, then turned off. I held the power button, to reboot it, and it worked... for a bit.

The usual "Powered by Android" screened showed up, before a blue flash covered the screen, and then nothing.

Panicking a little bit, I tried to boot into recovery, but then something weird happened. It hanged onto the TWRP screen, before rebooting back into the "Powered by Android" screen. The next time I tried to go into recovery, it hanged onto the TWRP screen again, before now slowly fading out into black with blue colours, and then nothing.

I have no idea what happened, but my phone is rooted, it has TWRP [obviously], and the internal storage was almost full when I was downloading the images. I'm a bit worried that the reason why my phone is glitching out is because the internal storage is way too full, but without a recovery I have no idea how I can fix that issue.

Anyone know what's going on, or is my phone officially dead?

Also the OS I'm rocking, or was rocking, was the Lineage 14.1 one by Nutsda

Thanks a lot
