[OnePlus 3 & 3T Cross Device Development] Mostafa Wael:
Sadly i rolled back to OOS to find something making my CPU stuck at max freq, wasted a whole day debugging and tracking the culprit to find it to be the Facebook app and its advocate. Reverted to the previous nandroid backup as a measure of safety since i need a functional phone (tomorrow I have an exam). Anyways, I had some things to say about the kernel here, will be back in some hours to spill the beans and say what I found.
[OnePlus 3 & 3T Cross Device Development] Jole7:
[MENTION=3637908]kairi_zeroblade[/MENTION] you have a Telegram group? I'm asking for test build you mentioned before about LineageOS.
[OnePlus 3 & 3T Cross Device Development] Mostafa Wael:
Now I admit I got a bit late, but it hasn't gone well for me in the last couple of days, and it got even worse with my exam today. Nevertheless, my deep sense of ought pushed me back to OOS and since all temps and freqs were in the green with the blue demons removed, i decided to remake my take on this kernel and right off the pat I noticed few things:

1- weirdly it "patches" my OOS version to 3.2.8 instead of the real 3.2.7 (yes I ensured that, just rolled back to stock kernel and system and it went back to OOS 3.2.7. And yes the zip I have is for OOS 3.2.7 and NOT 3.2.8

2- performance is spectacular, the only time I didn't feel the need to apply any of my Burnout PRs, only slight changes done to the sched and the gov to allow the phone to go into an "overdrive" mode when needed, something folks who preserve their juice wouldn't admire, unlike me - a man who loves the smoke of burnt tires and the sound of a mighty Dodge Charger Hellcat wrestling with them, leaving some petrol-head styled donuts behind

3- even tho I do not admire benchmarks as much, it was very natural to see a dazzling 1.85k (single core) and a 4.3k (multi core) in Geekbench 4 out of the box. And to top it off nicely, app launch times, with my minimal tweaks for the gov and the sched, were sometimes exquisitely fast, hitting as low as 4.49s of total time compared to the (sort of) traditional 5.3s I used to get with Burnout_PR2_golden on other setups, or the much slower default time of ~6s if you talk stock settings.

Can't say much on the battery and fluidity as I have just installed the kernel on a fresh install of OOS 3.2.7 so, i am sure I will have some other things to say as time passes. But as initial impressions end up here, i have to say it is quite superb up till that moment :good:

Further on to the observations, i notice that the latest build retreats to the previous S821 like clocks with "only" 2.34 GHz for the big cluster compared to the more insane 2.5 GHz that we had on the earlier build. Little cluster did see minimal but sorta strange change as well, going up to 1785 MHz when compared to the previous 1747 MHz. [MENTION=3637908]kairi_zeroblade[/MENTION] could you please elaborate and calm my curiosity? :D

Thanks!
[OnePlus 3 & 3T Cross Device Development] kairi_zeroblade:
1. maybe its because I'm using the ramdisk from 3.2.8..

2. I have not done much offscale tweaking, just clean a few stuff I found and the toolchain I use might have been also a factor.

3. we already broke 158k bro..

My intentions to go back to sane clock speeds are just to keep things stable..also I just want to point out that going further is doable..I already booted 2.6ghz on my phone and TBH when we deal with the heat performance is really crippled on this 4-core behemoth..

currently I'm just playing around the regulator codes and checking on what more can we save without hiccups..I'll maybe try to release the build I'm on but I'll give it a day (or two) more just to be sure..

@Jole7 I will try to look into LOS over the weekend, as a friend of mine (on another SD820 device) is also asking for my "simple" project to come over his device..I just wish someone from here would want to help test it out as I'm currently not using a custom ROM..
[OnePlus 3 & 3T Cross Device Development] Mostafa Wael:
Tho i haven't been a fan of overclocking that much, you made overclocking so much more fun. Also i would like to note that when i rolled back to the previous build of 2.5 GHz max freq, even with Burnout_PR2, it didn't get the same speed of the latest build with the saner 2.34 GHz max freq, and scores were 1801 + 4071 in Geekbench at its peak.

Looking forward to that insane 2.6 GHz build of yours truly
[OnePlus 3 & 3T Cross Device Development] Jole7:
I can test it for you sure count on me please.
[OnePlus 3 & 3T Cross Device Development] Mostafa Wael:
[MENTION=3637908]kairi_zeroblade[/MENTION] i am on it too :good:
[OnePlus 3 & 3T Cross Device Development] viper001:
Tester ready to flash on your word! ?
[OnePlus 3 & 3T Cross Device Development] dante_nfs:
I read the pages and I have some questions:

the GPU is overclocked to what frequency and is it stable?

the app opening speed in OOS4 is good, is this better?

and [MENTION=5060769]Mostafa Wael[/MENTION] what's your opinion about changing back to 3.2.8 from OOS4? does the speed difference worth? and try PCMark I think it's more realistic than the other benchmarks because it simulates real world operation.

I don't care much about battery life I'm going to sacrifice 30 min less SOT for great performance. give us a 2.6 Ghz and an overclocked GPU :D (seriously thanks for your awesome job man)
[OnePlus 3 & 3T Cross Device Development] Mostafa Wael:
1- I wasn't on OOS 4 actually, it was LAOS/CAF N all the time, so I don't know how OOS4 fares, but one thing that i saw is the incredibly fast boot time (it is like 1.7x faster!)

2- PCMark is one of the most reliable ones for sure, but still user experience wins hehe

3- It is not all down to the overclocking, you can achieve almost same performance with the right set of tweaks and configurations, and some kernel optimisations/toolchain settings, still that 2.6 GHz gives me a fuzz tho :D

4- I am a petrol head too, like to smoke the tires with a Hellcat and swoosh in the straights rather than early shifting with a reasonably priced Vauxhall Astra ;)

GPU is at 652 MHz IIRC
[OnePlus 3 & 3T Cross Device Development] kairi_zeroblade:
FYI GPU is now on 691.2mhz.. :p

also another FYI is, I do not tweak..there's no app installed on my phone for parameter tweaking..I just root (for debugging) and some bench apps..I did not even installed any scripts for tweaking as that would be "against" gaining a baseline result for the same setup..
[OnePlus 3 & 3T Cross Device Development] Jole7:
Damn this kernel is a monster great work man
[OnePlus 3 & 3T Cross Device Development] kairi_zeroblade:
I'm doing LOS now..who wants to take a ride?? I'm only available on G+..

BTW I broke the 160k barrier..(not using insane clocks, I do now get it, TZ is history..lol furthermore, no scripts or anything..just install and fly away)
[OnePlus 3 & 3T Cross Device Development] Mostafa Wael:
I will be down for testing starting from tomorrow
[OnePlus 3 & 3T Cross Device Development] liam_davenport:
If you've still got me on hangouts throw some builds up anytime :good:
[OnePlus 3 & 3T Cross Device Development] Jole7:
I'm ready to try the kernel
[OnePlus 3 & 3T Cross Device Development] crzykiller:
I gotta ask, why do you use AnTuTu so much to prove your kernel? You should try Geekbench, discomark or any other reliable benchmark, AnTuTu absolutely sucks and is real easy to get unreal scores (I can easily get >180k with this phone). I do like that GPU overclock though, I may just try out a CM ROM since I'm on OOS4
[OnePlus 3 & 3T Cross Device Development] liam_davenport:
Pm me 180k SS
[OnePlus 3 & 3T Cross Device Development] Jole7:
180K if you bench it in minus 60 temperature maybe lol!!!
[OnePlus 3 & 3T Cross Device Development] Mostafa Wael:
He is right, AnTuTu can be very easily faked via some dedicated tools, i seen some unreal scores like 210k and 200k. One of the tricks is to downscale the res of the app to something like 480p so that the GPU gets a huge boost and the UX slightly, to inflate the scores. But the real point that makes some users see AnTuTu as unreliable is that people often look at the total score and does not look at the sub totals, save for the details of each sub total.

And I would like to add that this kernel is not all about benchmarks, it is wicked fast. It possibly has the biggest brute force up till now, something I haven't seen before.

And if you want DiscoMark, it is also inconsistent and depends on a lot of control variables too. [MENTION=6295391]bedalus[/MENTION] can tell you more about it and how storage bottlenecks affect the scores (i have just learnt that now). Geekbench has been very inconsistent recently, more than anything else and i dropped it from testing.

TL;DR

Benchmarks can be inconsistent and unreliable, but weirdly, AnTuTu is the most consistent one :good:

And to treat AnTuTu well, read the sub totals and the detailed scoring of each of them. Also you cab run AnTuTu to verify it yourself hehe :D

Peace out

Oh and [MENTION=3637908]kairi_zeroblade[/MENTION] I will switch back to LineageOS N tomorrow, would be very pleased to receive a test build from you amigo :highfive:
[OnePlus 3 & 3T Cross Device Development] liam_davenport:
Best LOS kernel is almost here :cool: [MENTION=3637908]kairi_zeroblade[/MENTION] Is working his magic should be up in no time :good:
[OnePlus 3 & 3T Cross Device Development] kairi_zeroblade:
Wanted to thank [MENTION=5823687]liam_davenport[/MENTION] for spending the sweet night with me for testing LOS kernel..and we'd like to announce it boots.. :p (its still a small WIP, a few finishing touches here and there but its already upto Xceed status)

[MENTION=2809106]fuxmen[/MENTION] YGPM on Hangouts for Gemini, if your seeing this buddy..

[MENTION=5622852]Jole7[/MENTION] already dropped a PM on Hangouts, took me a while to find you..

Once my covert team is done with soft tests, I'll post a soft opening for the LOS kernel..hope I'm not too late for the party..lol :silly: (the dawn of Android Porn is yet to come!!)
[OnePlus 3 & 3T Cross Device Development] Mostafa Wael:
That is because thermal throttling kicks in, for consistent AnTuTu scores there must be substantial time for the temps to cool down. Anyways yea PCMark is a reliable one, I am going to use it and tell you guys how it goes :)
[OnePlus 3 & 3T Cross Device Development] Jole7:
Can you pm here or at my email chris_6449@yahoo.gr i don't have hangouts
[OnePlus 3 & 3T Cross Device Development] dante_nfs:
I think you got me wrong, i know about thermal throttling, i mean it gives better score than the first run. I think it may have something related to new ART compiler in nougat roms which google stated it improves after running the program.
[OnePlus 3 & 3T Cross Device Development] Mostafa Wael:
I will be testing today night (just broke my ankle now :/ and I am at hospital)
[OnePlus 3 & 3T Cross Device Development] SREEPRAJAY:

[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] kentaurest:
For all who are waiting for unlocking permission, you don't need to - if you'd like to root and install twrp.

Warning do not flash xiaomi.eu global or any other unofficial rom this way !

Good news - there is now patched aboot with installation instructions

I bought my redmi 4 pro from geekbuying and it came with preinstalled google play and semi mutlilingual (fake) Miui global 8.0.5.0.0(MBECNDG)

It seems geekbuying has installed a modifyed aboot (android bootloader), if you overflash it with xiaomi stock your device will check the rom for valid signing.

So you probably could flash unofficial rom if you don't flash aboot, but I can't test it anymore :/

btw I did this using linux and I used adb from Flashtool

As I still needed root so I tryed to unlock using fastboot :

First enable developer options by clicking on miui version in about phone menu

Go to Systems & Device > Additional Settings > Developers options

allow oem unlock and usb debugging

connect to the computer and allow access

turn off device

hold vol down and power - device reboots to fastboot

fastboot oem device-info

fastboot oem unlock-go

fastboot oem device-info < again, to check if its unlocked

restart device

Redo the setup and use browser to download supersu

get Recovery Flashable.zip

now download twrp to the computer

and follow the instructions how to install twrp.

Twrp started in chinese use, settings menu is second up from the right and last tab is language.

Flash supersu

I'll try this when I receive my Redmi 4.

Thanks for sharing!
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] d3s4nn:
It's that simple ?

[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] 333hronos:
Not working
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] jontseng:
Hi just to say this worked fine for me. Had a new Redmi 4 Prime bought from Gearbest. Fake global rom version exactly same as mentioned above. I used vanilla Minimal ADB and Fastboot.

NB when device arrived no setup ie fake ROM had already been installed and configed (presumably to install play store).

Went straight in and tried the instructions above. Worked fine. Fastbook unlock then TWRP then supersu. Dumped Chinese CM13 ROM on and we're all good.

Not sure why works for some and why doesn't. Perhaps the exact version of the global rom? Perhaps the fact hadn't done anything with ROM and dived straight in with the unlock?

Tx for kentaurest for the tip!

J
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] mulat666:
Did you check if bootloader was locked before? Maybe it was unlocked by Gearbest when flashing ROM?

PS. I'm waiting for delivery and I will check your method :)
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] jontseng:
Yeah so device-info before unlock was:

(bootloader) Device tampered: false

(bootloader) Device unlocked: false

(bootloader) Device critical unlocked: false

(bootloader) Charger screen enabled: true

(bootloader) Display panel:

Afterwards it was:

(bootloader) Device tampered: false

(bootloader) Device unlocked: true

(bootloader) Device critical unlocked: false

(bootloader) Charger screen enabled: true

(bootloader) Display panel:

[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] gicifix:
Tried with my Redmi 4 Pro who came straight stock from china. It worked. Be sure to install good adb and fastboot drivers and be sure to check the correct developers options.
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] alexeius:
One interesting thing is mine device which is unlocked with miflash shows the second line like this

(bootloader) Device critical unlocked: true.
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] mulat666:
I've just received phone with the same ROM as in first post. Could you please share ADB drivers? With universal I had:

fastboot.exe oem unlock-go
...
FAILED (remote: Token verification failed, reboot the device)
finished. total time: 0.030s

The same issue on Ubuntu 16.04 :(
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] jontseng:
Yeah mine is still "device critical unlocked: false" even after flashing other ROMS and mucking around.

Not quite sure what the issue is - did some quick google as maybe its some key system stuff still locked or because I didn't officially flash thru edl mode or something?

Not going to worry about it too much as I seem to be able to flash ROMs and stuff just fine (just flashed XPosed framework as well, FYI). Don't plan to go back to MIUI at any point anyhow - not really my cup of tea.

Would be interested if someone can explain more about this though. What am I missing out on?

PS Just for fun I ran the same fastboot device-info on my old redmi 3 (unlocked the official way) and it didn't have the "device critical unlocked" line at all (true or false..)
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] kentaurest:
It is dangerous, you can install supersu and twrp this way, but don't flash non official roms.

Xiaomi roms should relock the bootloader.

Also don't try to install xposed, it didn't work for me.

After xposed made my phone bootloop I installed unofficial global and ended up with "bricked phone" left only with fastboot or black screen (qualcomm diagnostics interface 9000E) and couldn't turn off the phone.

I made deep flashing cable - usb cable where you can short GND and D+

http://xiaomitips.com/media/2016/08/Deep-FLash-Cable-Architecture-680x318.jpg

Connected phone to the computer (don't short the cables yet), used "fastboot reboot" to restart phone.

Quickly shorted GND and D+ for a few seconds, then windows installed HS-USB QDloader 9008 driver

and I could use Mi Flash to restore the phone, this time to the china developer rom

(fastboot version ends with .tgz) with clean all and locked options.

I was quite happy with fake global, twrp and supersu, pity xposed ruined it.
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] kentaurest:
Use deep flashing usb cable to get to EDL (downloader) mode.
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] mulat666:
@kentaurest I have a cable, would it work with the same fastboot commands?
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] kentaurest:
Use windows and Mi Flash... as I described or use official unlocking method.
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] jontseng:
Hi Kentaurest tx for this. Forewarned is forearmed I guess.

So I assume it was the fake global ROM you were having trouble with re: Xposed - you hadn't flashed and other ROMs right?

(I have Xposed working on the 25/11 CM13 ROM from the China MIUI forums... But I guess its something of a crapshoot which ROMs do and don't break the device..)

To clarify (for future) - when you say "don't flash unsupported non xiaomi roms" do you mean any third party ROM, or ROMs now built specifically for the redmi 4?

Tx

J
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] kentaurest:
To my understanding bootloader checks if the system is signed with xiaomi key or not... so all xiaomi stuff will load, but xiaomi.eu unofficial global would not.

Also there is special Xposed for Miui, which I didn't try, last pages in the thread seem to suggest to use v86.2

http://xdaforums.com/xposed/unofficial-xposed-miui-t3367634
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] Mithrandir107:
Some others used this method instead. for 900E problem. https://www.youtube.com/watch?v=j27x5iJSS40, seems to work for th. Just read it from other forums
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] jontseng:
Hmmm. Funny the CM13 ROM runs then.

I suspect given kernal sources haven't been released they are just using the official build kernel, hence it passes any checks?
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] pilililo2:
I discourage anyone to try this method as people have bricked their phones after doing this. Official Xiaomi unlock will also set Device critical unlocked to true, so it is not the same unlocking procedure.
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] kentaurest:
I'm thinking that shops have modifyed emmc_appsboot.mbn so they can unlock and install the fake global rom.

But when we flash factory emmc_appsboot.mbn and non xiaomi rom, it will cause trouble.

Like Redmi note 3 users do

If we could get the emmc_appsboot.mbn from a new phone with fake global rom and compare it.

Another way to test would be to delete emmc_appsboot.mbn from the rom you'd like to flash or use modified twrp which skips flashing that partition.

redmi note 3 patched twrp solution
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] fillonov:
If I do fastboot OEM unlock - and will get state TRUE, can I be OK to flash any ROM?
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] pilililo2:
You should not use fastboot to unlock bootloader in Xiaomi phones as Xiaomi doesnt provide the bootloader unlock code. Use the original unlocking process even if it takes a week.
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] Wilderone:
I agree why bother, stop being lazy & impatient & go do some posting over on MIUI.com & then apply for Unlock, I got mine in 4 days & the average seems to be 3-7days depending on weekends I think.
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] jontseng:
Wildone, I don't think you understand. We don't try things because we are lazy and impatient. We try things because we can. We love to tinker, and to share with other users what we discover.

Not all of us may be hot shot IT consultants like you (I'm more of a script kiddie myself). But it's more educational to mess around and occasionally brick stuff (it happens, which is why I'm doing this on a £125 device which is to all intents and purposes disposable) than to be lazy and follow the manual.

Heck if I was lazy I'd be running a Samsung Galaxy stock, or heaven forfend, an iPhone.
