I've been looking at the benchmark results for E4 and noticed that the Mediatek variant has sub-optimal AES performance compared to the Qualcomm one.
Specifically, the Qualcomm version scores about 300MB/s/core while the Mediatek falls short at 15MB/s/core (!).
The MT6737 arm core is actually the same as the Snapdragon 425 (i.e. it supports the hardware AES accelerator) however it seems not enabled in the kernel.
I found some MT6737 based phones (like the Asus Zenfone 3 Max) where the AES speed is approximately the same as the one in Qualcomm.
Other designs however exhibit the same poor performance.
Now this is something that could be easily overlooked during the compilation of the kernel, but it has dramatic effects when running a VPN (say to the office). The Qualcomm variant will hardly notice the VPN while the Mediatek will use most of the processors for AES encryption/decryption and become sluggish, battery-hungry etc.
Not to speak about the crypto world (i.e. wallets etc where aes is also used for verification and general checksumming).
Can you confirm this is an issue with the mediatek version of Moto E4 ?
If possible, I'd like you to test and report about download/upload speed tests performed while under VPN (OpenVPN and similar). VPN normally use AES ciphers (either AES128 or 256) so that will be a good indicator about speed of the AES acceleration.

It's a $50 phone. If you're looking to do resource intensive things, and crypto type things, and super speed is necessary... Spend a couple more bucks. That said, I have the Qualcomm version and using a VPN works fine. Pure VPN in my case. But it's doubtful anyone is going give you the response you want, it's an entry level phone. Get one and test it. I've seen them for $25.

Exactly! FWIW - I have a Qualcomm variant and run a VPN based firewall 7x24 with zero subjective performance hit. Haven't bothered with objective analysis as throughput and battery endurance exceed expectations for a budget device.
Sorry, I think I did not make myself clear.
I understand it's a cheap phone. It's more like $100 without operator subsidies in Europe too, but this is not the point.
My point was more technical. I noticed that *this* phone, in the MTK version, regardless of having the right CPU with hardware AES support, did not seem to be using it. So I sought some confirmations (because I don't own it atm). Take my thread as a bug-report if you like pointing that the kernel for MTK missed something. I know the Qualcomm is OK, as I wrote in the OP.
And, IMHO, VPN is not advanced stuff at all. It's rather a basic security provision everybody shall just keep in the background of their phone while connecting out of their own home, and I mean even using mobile service too, in addition to the obvious free and unsecured wifi hotspost that we all like to use.

I didn't say it was advanced, I said "resource intensive".
I was pointing out (admittedly sarcastically) that I doubt anyone is going to give you the answer involving the testing you're requesting.
I know a VPN isn't advanced, I use one on all my devices, have for years. Nothing you said was "advanced", I just don't think anyone cares enough to do the testing you're asking.
Granted, I worked long hours that week and was a little "rough" on you. But it doesn't look to be getting responses.
Sorry for being ... Well, kinda jerky.
And most Qualcomm chipsets are going to outperform similar mtk ones.
No problem man. Perhaps somebody from lenovo will see the thread and (dare to) fix the E4.
Meanwhile there are perfectly good MT6737 based chinese copy-cats that work at the same speed as the qualcomm (it's the same cpu core ater all).

I am curious why is this not possible to easily port ATT froyo rom to run on Vibrant (well if possible then probably not easy) ?
They are the same phones, same hardware, etc.....

One would think, however, FROYO does not run on a commodity operating system but instead requires a computationally distributed version of Fiddlefark Version 7.2.
We implemented out the partition table server in Simula-67, augmented with opportunistically independent extensions. Our experiments soon proved that instrumenting our Vibrants was more effective than distributing them, as previous work suggested. Along these same lines, we implemented our FROYO server in Depildoo, augmented with extremely exhaustive extensions. We note that other devs have tried and failed to enable this functionality.
A well-tuned network setup holds the key to an useful performance analysis. We executed a simulation on our Internet testbed to quantify O. N. Nehru's deployment of Captivate FROYO. Had we prototyped our Vibrants, as opposed to emulating it in middleware, we would have seen duplicated results. We removed 150GB/s of Wi-Fi throughput from our mobile telephones to better understand the effective NV-RAM speed.
We then removed more RAM from the KGB's 2-node cluster to consider our system. Next, we removed 3 RISC processors from our Vibrants to quantify the change of steganography.
In the end, we removed more optical drive space from our scale overlay network to disprove the independently relational nature of linear-time symmetries. The results were not promising.
End-users of Silonia development models, as applied to the Samsung Galaxy S, agree that unstable symmetries are an interesting new topic in the field of noisy FROYO lust theory, however, all research concludes that it is not possible.
I hope this clears things up.

Since I'm active member of this section, I'll begin questioning here. Should I commit to building ROMs in the future, I'll post elsewhere as my edumacation broadens.
I spent 10 years in IT as hardware tech, tech support manager and systems admin. When the economy tanked on '08, the company I worked for quickly began to fold. By '10, I was out of work. I spent the last year with the company closing down call centers in Northwest Indiana and Illinois. Centers across the nation began doing the same. I watched laborers dismantle these centers and throw away hardware by the dumpster load. It was unreal. As part of my 'severence package', corporate allowed me to cart away anything I wanted. Server cabinets, Cisco routers, dialogic servers w/T1 cards and 5 monstrous Intel servers, among other things. Most of the hardware sold quickly except for two Intel SSHCBPBK servers. They ended up in storage.
Long story short, storage gets cleaned out and two servers emerge from the dark. These SQL servers still boot. I forgot the specs and started hunting for info today. Coincidentally, while searching, I found my FS post from '09. That caught me by suprise. Quad Xeon , ICP Vortex raid cards, 10 SCSI drives per server, yada yada yada. Loud and power hungry. The kick in the balls is they only have 1GB ram each.
https://hardforum.com/threads/sale-trade.1385541/
My question is this: can these servers be utilized to build ROMs? Overkill? Too old? I would imagine I'd have to bump up that ram count significantly. I'm not even sure I could get old ECC RAM to fill it. Let me know what you think. If it's feasible, and I commit to it, I'll go from there. Since I have no immedite plans to dump the Axon 7, this would be a good starting point to learn and hone my skills. I might even revive my old LG G3 as a practice device. If not, I'll pitch these heavy behemoths and consider other options. I have a lot of hardware collecting dust.
The quest beings now. I have plenty of reading to do as I get back to my roots. Quite exciting. Transitioning from white collar IT to blue collar laborer was a struggle. Regardless, my passion for tech lives on. I hope to contribute to the ROM community in the future.
I would think a modern and fast quad core with hyperthreading and a shed load of RAM talking to a RAID array would be the best system for compiling ROMs but I'm no IT expert.
Anything old will be inefficient? I have stuff from times past collecting dust. Probably turf it in the bin when I have spare time. One of the issues is continued relevance running modern OS and software. Old hardware is a PIA.
I tried building a little while back when I wanted KCAL on stock N as there was no community development for it. I ended up stuck due to ZTE kernel source being incomplete.
While searching around information and guides I found it's a common recommendation to try Google Cloud Platform. First year or so trial is free with no obligations, saves a whole lot on hardware as well as getting and keeping it running. It's priced for large corporate use so personal consumption doesn't even cost much in their pricing scheme, especially compared to owning matching hardware. It's pretty nice commanding state of the art hardware and networking with just a touch of a login. It's actually a better way to try out building to see if it's for you and decide from there. A hurdle with building in our situation for a beginner is ZTE beta source code.
I'll definitely keep that in mind. Thanks.
Hi All,
My current home network is not protected by a VPN across all ports/units, rather I indiviudally conenct to a VPN when required on a specific device. Given the state of things, I would really like to get my whole network behind a VPN, but want a capable switch that won't limit me (too much) in speed.
My current setup:
Cable modem in bridge mode ----> ASUS AC66U router (WiFi disabled, DDNS enabled through afraid.org)
----(Port 1)--> Ubiquiti AC WiFi Pro (this is my WiFi for the house)
----(Port 2)--> POE switch ----->4 security cams
----(Port 3)--> dumb switch #1 -----> multiple devices throughout the home
----(Port 4)--> dumb switch #2 -----> multiple devices throughout the home
I have various streaming devices, NAS and gaming systems that take advantage of the internet, as well as 3 kids that consume YouTube videos like there's no tomorrow.
My primary concern is a balance of speed and security. My internet plan now is a 150mps/10mps service.
I'm hoping this group might have some recommendations on a powerful/affordable VPN router/switch. As you can see from the above, it does not need to be WiFi capable as I'm using my Ubiquiti router.

Why not just install openvpn on your AC66U? You're barely using it as it is with wifi disabled. The Asuswrt-Merlin firmware project is an excellent 3rd party firmware for ASUS routers that includes excellent VPN support and you should be able to find a VPN based Merlin firmware for your AC66U.

I've tried that and my throughput drops significantly. I don't have the numbers in front of me now, but clearly the processor on the router is not robust enough to manage the extra load.

Yeah the AC66U's are still using the pretty dated MIPS74K, so that would surely be a drag on the VPN with lots of devices.
The Netgear Nighthawks are the best performing consumer grade wifi routers on the market. The latest X10 R9000 running a high performance 1.6 gig @ Arm A9 Quad would make a HUGE difference than what you saw on your single core MIPS74K. But you might not be feeling like dropping 400 bucks on a wifi router when it sounds like you're happy with the performance of your Ubiquity.
But if you could live with about 80% the speed of the R9000 you could get away with paying less than half that for a Nighthawk R8000 which uses a 1 GHz ARM A9 Multicore or even a Nighthawk R6700 which has the exact same proc specs but I've seen going for under a hundred bucks. The R6700 and the R8000 share the same CPU and therefore the VPN performance will be the same, but the R8000 is tri-band while the R6700 is only dual-band. So it'd be up to whether you'd want to pay more for that extra 5 gig radio.
Install DD-WRT and openvpn and you'd be on your way.

Mikrotik, is the way to go.
With a bit of a learnig curve you could program them to do whatever is needed.
or a Ubiquiti edgerouter if you want to stay with Ubiquiti
Mikrotik is similar to Cisco type configs and a fair bit cheaper.
Since we moved over to them we have not looked back.

No need to root to switch to another isp. get unlock code from current isp, install odin 3.14.1 and install any isp firmware you want from https://galaxyfirmware.com/model/SM-T307U/ I had an at&t branded with android9, and now i am running wind/freedom android11 firmware.

Hi, thnx for the useful info. Did you have trouble getting the unlock code from at&t? Where did you enter that code? A specific app on the at&t rom I'm guessing?
Getting a sprint version of this device, but want to use it t-mobile. Have read that just factory reset device and use odin to flash other firmware would work, does that sound feasible to you? I'm kind of doubting that but have no idea really.
It used to be flashing diff rom would sim unlock, but not anymore I don't think.
thnx for taking the time, so little info for this available.
cheers
No problem with at&t, although i had to impersonate a US location. Start here: https://www.att.com/deviceunlock/unlockstep1
Like I said, vendor unlock, install odin on your pc, use odin to install the desired firmware you downloaded.
The firmware should boot up, but maybe the radio bands are different between the two isp's? and therefore the LTE part of the tablet may not work. i don't care since I don't install a sim card, just use it on wifi.

How is the speed/lag? This tablet is mega slow, but I was wondering if I loaded different firmware (currently on AT&T) that it might help, since it can't be rooted.
My 8-yr old rooted Galaxy Tab S 8.4 is better than this thing, but alas a few apps won't run on 32-bit architecture. I think I will relegate this AT&T "brick" to my exercise bike for an entertainment interface.

Meh - no better. It is pretty ridiculous - I was very happy with my 2015 Galaxy Tab S2 8.0 - but it started crashing all the time. This one is slower, thicker, lower resolution, and heavier! 32 GB really isn't enough storage either.
It is super annoying there are not any good 8 inch Android tablets. The Huawei M6 8.4 looks okay, but being in the US it is a bit of a pain to get.

The only great 8" tablet is the Lenovo Legion Y700, running SD870 with 12gb ram. 2560x1600, but IPS and not OLED.
I own the Tab S 8.4 (2014), the Tab A 8.4 (2020) and the Y700 (2021, 8.8").
Tab A is terrible.
It's painfully slow.
It needs root.
It has the same RAM as a tablet 6 YEARS older than it, with LOWER resolution and ! much worse performance. I wish it could be fixed.... Android 10 Lineage is out for Tab S 8.4.

I have done quite a few mods/tweaks to system/Global/Secure settings and also disabled Gaming Optimization Service (GOS) via Alliance Sheild X, it has made a MASSIVE difference. This device's (SM-T307U) performance is being HEAVILY limited by software-based restrictions. Most of which can be disabled without root. I can go into more detail as to how ive sped up this device if anyone is interested.
NOTE - If someone has the ATT version and can drop the .IMG or Firmware .zip that'd be awesome.
Ill keep trying to find a way to root this device until i get a new one, if anyone else has any success, DM me.

I've already deleted, turned-off and disabled everything I can. It's a good bit snappier, but still a dog.
I actually have 2, so I may play around with deleting/disabling apps via ADB. But it's not battery drain, which with some securetask special permissions I've gotten it to SIP power while the screen is off (varies, as low as 2% per day up to about 6-7%).
I checked the usual sources and couldn't find any AT&T image files.

Yeah this this is good on power, it is just severely limited. Judging from similar devices with the same exynos processor, there's got to be something holding it back. I again recommend using SetEdit or something similar to modify some params in the settings tables. The line I highlighted is in both this tablet and my Galaxy S22 & S21. I also found a param in there called "Enhanced CPU responsiveness" which was set to off, after turning that on, I noticed a massive gain in my tablet.
Also worth noting is I added the line "Allow_more_heat_value" with a value of "30" and it allows all cores to boot to max.

I'll have to give this a shot. I wouldn't think AT&T throttled the CPU, which means Sammie did it for some reason. Probably to hit some sort of battery life benchmark. Or maybe it caused instability in some devices. But being a mid-tier processor you wouldn't expect that it needed to be throttled.
I believe Sammie is giving up on the Exynos processors. I bet they had issues on this tablet, said "screw it" and just **** this out with a throttled cpu.

From my understanding, it's done because they use many of the same parts/processors in various devices, so as a way to control device specific performances, they set limitations. For example, this tablet has the same processor as some of their other "Higher-end" models (if I'm not mistaken), so to keep this tablet from outperforming the others, it's limited. I'm sure there are other reasons, like the battery benchmark bit that you mentioned too.
But yeah. This is 100% a Samsung based throttling.

I have done quite a few mods/tweaks to system/Global/Secure settings and also disabled Gaming Optimization Service (GOS) via Alliance Sheild X, it has made a MASSIVE difference. This device's (SM-T307U) performance is being HEAVILY limited by software-based restrictions. Most of which can be disabled without root. I can go into more detail as to how ive sped up this device if anyone is interested.
NOTE - If someone has the ATT version and can drop the .IMG or Firmware .zip that'd be awesome.
Ill keep trying to find a way to root this device until i get a new one, if anyone else has any success, DM me.

I’d be interested in how you tweaked this tablet to function better.

Can you please share the mods/tweaks you've done?
I have one of these purely for its size, I travel over Europe and as the seating space is limited the smaller the better. I am running the Canadian Wind software but if anyone can give me a run through on disabling apps/services to speed up a bit that would be helpful.
I am going to buy the Lenovo Legion Y700 but only when a global version with LTE is available.
Cheers

Found this apparently interesting TV box more or less recently. It's sold at a very attractive price, and can be bought in configurations with up to 8 GiB of RAM and 128 GB of storage, so I guess that it must come with a 64-bit operating system or firmware. And well, according to “REVIEW: X88 PRO 20 a low-cost Android TV-Box with SoC Rockchip RK3566 @ AndroidpcTV”, the TV box's firmware supports the arm64_v8a ABI, so 64-bit yes.
About this box I only found the thread “X88 pro 20 RK3566” opened close to a year ago, but it contains just a confusing question and no further information.
So, may some of you provide feedback about this TV box? It looks appealing, but of course I need to be able to root it; this is the single most important factor. Once rooted, any limitations in the stock ROM can be fixed and it also is fully customizable; just hope it is stable, of course.
Can someone provide information on rooting this box? Custom firmwares?
Thank you.

I have one, and the only method for rooting is installing another rom, I think the rom with root is the "hk1-rbox-r2-RK3566_DC_R2_HK5235F_11_20210705.1409", but the T95 Plus and H96 Max rom also works (but it doesn't have root), other thing you can do is flash a linux debian using the tutorial described in the forum t95plus.com, but sadly my x88 pro 20 is defective, every app I open (while using android) crashes after some time, and while in linux firefox keeps crashing, I don't know what's the issue, and since so few people have this box I can't find anyone else having this problem
Thanks for contributing, GamingSoldier. My interest in this box sort of vanished, mainly because I was just finding a good TV box solution to pair with an old good TV which I have lying around for someone else, and that someone else decided to buy a new inexpensive set… Of course, suffice to say these people must not be aware of the very limited Android system they are getting, or of how much better it could be.
Anyway, I digged on the subject of rooting without a custom recovery, and found the following very helpful video and article:
Extract Boot.Img Directly From Device Without Downloading Firmware @ DroidWin
This pretty much enables rooting of any device with minimum hassle.
Besides this, I'd love to know if the ROM of this device is stable and works well. I understand you are probably not going to say much in this respect, GamingSoldier; unless you get a new one, that is.

I don't know if the rom is stable, because my x88 has a hardware issue that keeps making apps crash, and it's not the software because I tested multiple ROMS and all of them cause this issue, about the magisk, I already know the app, but the magisk is unable to patch the rockchip boot.img
Well GamingSoldier, it's clear that you would need to get a new RK3566 X88 Pro 20 for testing its ROM, or at least fix the problem your box has if you are able. Speaking of which, did you open the box to check inside already? Because the problem could be something simple to fix like improper SoC cooling or some electronic component. After all, if the box doesn't works there's nothing to lose in doing so except a little bit of time and effort.
Concerning Magisk not being able to patch the RK3566 boot.img (sure?), I was going to say that you could say something in this respect in the Magisk thread, although I see it was closed long ago. So, the best thing to do is to inquire topjohnwu directly about Magisk's support for Rockchip SoCs, I guess. There's also topjohnwu's GitHub page with further information and etcetera.
And now that we're here I am not going to say that these boxes probably suck in certain ways, although I could. A working hardware matters, and proper working software matters too.
A tad off topic, very recently I've been checking the Orange Pi 5 Plus, for whatever reason. It uses a far more powerful and fully fledged Rockchip RK3588 SoC, and I see it somewhat below $200 (or even a hair below $180!) in 16 GiB of RAM configuration and including USB-C power supply. It clearly is something in another league, and very recently got new Android 12 images for SD card boot and fast 2280 M.2 NVMe storage boot; and it has accessible source code, which is very important developer wise.
It's a lot more money to spend at, but it also is a real Android computer which you can attach to TVs or monitors…
First thing I did after the apps started closing was to open the box and I added a bigger heatsink, I also tried increase the SOC voltage to see if it was a low voltage issue, and if I'm not mistaken I also tested the ram while I was using linux, and still, a paper weight...
After I discovered this issue and was unable to fix it I started to flash any RK3566 or RK3568 rom in to my x88 pro 20, most of them appear the logo screen, but are stuck in that image, I don't know much about these rom's, but might be just one thing or two preventing me from booting into the system
