[Android Q&A, Help & Troubleshooting] DocRobson:
Hi everyone,

I'm considering building a new Custom ROM for my Teclast X98 Plus tablet to get new features and security updates.

However I've never done that before, but as there are other Custom ROMs I think it must be possible somehow ;)

The Android version of the original firmware is 5.1, also Mireks ROM for the tablet is based on that and also the available Remix OS 2.0 I guess.

My question is: Do you think it is possible to build a mostly working ROM based on a newer version like Marshmallow, Nougat or even Oreo?

And is it possible to extract the proprietary blobs and drivers from an existing ROM and get them working on the newer Android?

I've seen that on other devices, but I don't know where they got the blobs and other stuff needed.

Any input would be appreciated :)

That's not how you measure sot.
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
I smell something funny as the longest times are 7 to 10 hours
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
Yea post pics of the proof of 17 hours of screen on time

AS this is not possible
[Samsung Galaxy S8 Guides, News, & Discussion] callumbr1:
Screenshots of SOT?
[Samsung Galaxy S8 Guides, News, & Discussion] n19htmare666:
Here is one from last night, about 17 hours. Still trying things to get it higher
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
it shows right there 5 hours of screen on

you where only on batt for 11 hours where you coming up with 17
[Samsung Galaxy S8 Guides, News, & Discussion] n19htmare666:
Look again. 11:50 "screen" with only 70% used equals 17 at 100%
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
no no no thats 11 hours active awake 5 hours 7 min sot
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
look in reg bat stats under screen usage
[Samsung Galaxy S8 Guides, News, & Discussion] n19htmare666:
Happy with this one? It says it at the bottom now.. notice how the numbers tie up before I rebooted into twrp and backed up. Others on echeo are also getting this :) enjoy
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
7 hours ok There are a lot of us that have pushed 7.5 hours and not have this much debloated

And it say 93 % there is no way you have 93% and 7 hours sot there is something wrong

let me see your charge history in stock batt app
[Samsung Galaxy S8 Guides, News, & Discussion] callumbr1:
So your average is 7 hours 3 mins. Highest you have got is 11 hours? We need to see 17 hours. Because what your saying is predicted 17 hours...
[Samsung Galaxy S8 Guides, News, & Discussion] n19htmare666:
Try it and see. I'll run another test tonight and post system screenshots for you :)
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
Thats just awake time not actual SOT the cpu was awake for 11 hours
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
I've used 12 % and what nearly 2.8 hours. Across 17 hours on batt 16 hours sorry.

As I only can charge to 80.
[Samsung Galaxy S8 Guides, News, & Discussion] n19htmare666:
But you have charged... Anyway I shouldn't have shared if this is the community attitude. I'm getting 17 hours. Up to you if you take it or leave it.
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
yea i charged 16 hours ago
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
its nothing gainst you, But it is not possible to get 17 hours of screen on time
[Samsung Galaxy S8 Guides, News, & Discussion] callumbr1:
There's no attitude... we just want to see proof of 17 hours?
[Samsung Galaxy S8 Guides, News, & Discussion] n19htmare666:
That's funny because I am and so are other people on the echoe forums. I thought I'd share on xda to see if there are any other things I'm missing from my setup. I'll run a test tonight and take loads of screenshots for you. :)
[Samsung Galaxy S8 Guides, News, & Discussion] TheMadScientist:
Im sorry if I came off rude but it is really hard to believe as longest is like 8.5

I am just skeptical...:good:
[Samsung Galaxy S8 Guides, News, & Discussion] n19htmare666:
no worries, I'm here to get info off folks that can make it even better. I'm going away for a week in the mountains soon, hence my reason to get this as high as possible since I won't be able to charge it when I'm gone. I'm happy to share all my testing, which has taken a long time with everyone for the better of the communities I'm involved with. It's a bit disappointing to have 3 pages of concern and not one suggestion to improve the setup. I hope this changes in the coming days.
[Samsung Galaxy S8 Guides, News, & Discussion] n19htmare666:
If anyone knows which of these seetings is best for battery, left or right for each item (even if it's only one or two) that would help:
[Samsung Galaxy S8 Guides, News, & Discussion] 5770mp:
(((There is:

1. use prediction.

2. Used 'today'

3. Average use)))

You have read the average use , not what he used today (he doesn't have 7h sot with 93 remaining)

From what I see- average use: 7h sot, maximum sot he have is 11.8h.. (with 30% remaining according to the screenshots he shared before)

[Samsung Galaxy S8 Guides, News, & Discussion] Norup58:
Seriously…..thats your input/ feedback??

OP makes a pretty comprehensive guide on how to achieve 17 hrs SoT by using his setup.

You find something you don’t like in the guide you don’t criticize you leave it out and be happy with e.g 16 hrs Sot.
[Samsung Galaxy S8 Guides, News, & Discussion] loris100:
This thread is crap and should be closed...He doesnt provide any proof and there is no way you can get more then 10 hours SOT in best case scenario...
[Samsung Galaxy S8 Guides, News, & Discussion] -Ric-:
The real question is, why would you even wanna look at your phone for 17h after you've turned it into a complete piece of garbage by nerfing it to hell?
[Samsung Galaxy S8 Guides, News, & Discussion] 5770mp:

It's better to see that the discharge screen as mentioned before.

Thanks!

---------- Post added at 06:50 PM ---------- Previous post was at 06:48 PM ----------

Averages are calculated ones and not the true sot. So there are no 13h.....
[Samsung Galaxy S8 Guides, News, & Discussion] n19htmare666:
True true :) I'll look to get some up in the next few days. It's not a test phone, but my day to day one so actually finding that amount of time to test without using uber, streaming to sonos etc. is hard work :) but I'll do my best. In the meantime do you think there is anything I have missed off the guide? I was told to try data saver option, so might give that a try as well.
[Samsung Galaxy S8 Guides, News, & Discussion] n19htmare666:
Use the first screenshot (not the second) and you'll see 11:50 SOT with 30% left = 17 but I'll post more in the coming days after a few more cycles. I don't mind if it's good or bad, or whatever. just looking for ideas of further things I can do to improve the battery further.
[Samsung Galaxy S8 Guides, News, & Discussion] strongst:
As you can see in my linked post you can monitor with better battery stats and post a dump file as its more detailed for further analyzing of the phones battery behavior.

Otherwise I can recommend this thread https://xdaforums.com/android/general/guide-extreme-battery-life-t3095884

Anyway, if there's no proof of what you advertised in the header of the thread, you'll know what will happen...
[Samsung Galaxy S8 Guides, News, & Discussion] n19htmare666:
yep. justed to follow that, but don't like Xposed (kills the battery these days). Do you know of any on-Xposed versions of amplify to stop alarms etc?
[Samsung Galaxy S8 Guides, News, & Discussion] :
Show us your normal day to day SOT. When you use the left out features.

Some people might make this their main setup and not have it as a "test phone".

We are not interested in "under certain circumstances (watching only youtube), you can get 17hrs SOT"
[Samsung Galaxy S8 Guides, News, & Discussion] n19htmare666:
Okay nevermind. I'll take this down... I don't know why folks are so unhappy with sharing all the information in XDA. Other forums that will remain unamed are much core focused on the problem in hand, how to make the setup perfect.
[Samsung Galaxy S8 Guides, News, & Discussion] strongst:
The problem is, as discussed before, you advertised ~17h of sot.

But there's no real proof as seen before. So why should anybody be happy with that? Why should anybody trust you? You see all the comments here.

For me and others this https://xdaforums.com/oneplus-5/review/screen-time-t3646100/post75452269 is a proof of sot. No calculated values no averages, no unclear information. Just clear details.

Please provide it to avoid further discussion.

Thank you for your help and understanding.
[Samsung Galaxy S8 Guides, News, & Discussion] n19htmare666:
Well if you have 11 hours 50 mins of screen on time (which I posted a screenshot of), and you do the maths, you end up at 16.9 hours after 100% battery use.

I will continue this here: http://echoerom.com/thread/2013-oreo-ultimate-battery-guide-17-hours-sot-at-the-moment

However, I'm wasting time here without getting any useful suggestions. I'm quite a busy person (I don't have hours to sit around running tests for 17 hours a day. People demand things instantly, but there is only one way to get screens of this, and that's by waiting) and maintaining this here was meant as a gift to the community, but that clearly wasn't appreciated. Sorry for that. I'll post some screens in a few days as promised so folks can see more.

But I'm happy for the MODs to close this. I have already sent a request.

Many thanks.

I am running Duttys March 4 Dual Touch, No Cube on my Kaiser. Probably unrelated, but yesterday every thing on my 6GB Sandisk Storage Card disappeared:mad:

About 750mb of data! The card appears empty in File Manager until I select "Show all files" when a single folder called WMDRM containing a single 132kb file shows up.

If I go to Settings> System> Memory The storage card shows 738mb used and 5084mb free. So it appears the data is there but inaccessible. If I browse the card from activeSync the same is also the case. Properties tell be 738mb used, but nothing is visibel except the single small file.

Any ideas on how I might be able to get it back? Really want to get my data back....
[Tilt, TyTN II, MDA Vario III General] cushcalc:
Storage Card scrambled files?

You may have scrambled your files.

Put it into a USB card reader and try to access it on your PC - if it looks the same there, try looking at it with a good file undeleter like Fix-It Utilities or Norton, see if you can recover anything.

I just had a laptop hard drive fail on my last week, so I feel your pain. Fortunately I had fairly recent backups so I didn't lose too much.

Makes me think of someone's tagline I saw once:

"There are 2 kinds of people in this world, those with a backup plan in place, and those that have not yet had a catastrophic disk failure"

Good luck!
[Tilt, TyTN II, MDA Vario III General] wisniak:
Search this site for SD CARD2

Most likely the issue is cause by the infamous Win CE bug.

If I have not posted the solution here, do a google search in the Web, you'll find detailed instructions.

[Edit] Your data is there, so don't do anything foolish, or else you'll have to reinstall everything. The SD CARD2 issue is very simple to resolve.
[Tilt, TyTN II, MDA Vario III General] logger:
Thanks guys. Had a look as SD CARD2 threads and they did not seem to relate to me. Ran Pocket Mechanic and its Scandisk feature on the Card and it reported loads of "lost clusters". I then ran it again with "Automatically fix errors" and "discard lost clusters" and it merrily removed them all. So now my 738mb of data has gone. Rats. Oh well I will just start again a fresh and hope it does nto happen again.
[Tilt, TyTN II, MDA Vario III General] somynex:
i feel your pain. it's happened to me quite a few times on my XDA II, and once recently on my Kaiser when i damaged the mini-usb port (entirely my fault) and it started writing corrupted data onto the card when copying files over through activesync

I've since taken to keeping copies of my card data in addition to backups of my device. i usually carry 2 cards with me, one backup and one "current"; and i also keep backups of my SD cards on my PC, just in case.
[Tilt, TyTN II, MDA Vario III General] logger:
Strangely, After a few hours most of the data on the card spontaneously returned. One minute it was empty and the next it had all the folders and files back again. Albeit with a lot of lost clusters and a heap of files reported as 32kb. Was able to recover a lot of the stuff and have got another 2GB card to use in the mean time.

Is there much point in reformatting the card? From experience, does anyone know if formatting might "fix" whatever caused it to lose clusters and go bad? Am considering sending it back for a warranty claim but how can I ascertain if it is actaully faulty once I reformat it.
[Tilt, TyTN II, MDA Vario III General] cushcalc:
Reformat or replace?

I have had USB flash memory seem to be faulty, especially when trying to transfer large amounts of data for a backup - then rebooted and re-inserted and had readable data. I would try reformatting, and then back up often and watch it like a hawk. Or, if it wasn't too expensive, just discard. Or, try to get a replacement - I did get an SD card replaced once at N/C because it wouldn't read in anything I tried it in, and I complained and was heard.
[Tilt, TyTN II, MDA Vario III General] logger:
I bought a replacement 2GB panasonic microSD in Japan a couple of days back. (Always find the memory quality excellent there.) Their eyes were out on stalks when they saw my 6GB card. Must not be wideley available there yet. Anyway I plan to use the 2gb for the time being to rule out hardware and software causes. Have reformatted the suspect 6gb card. Will soon start using it again with everything backed up to the max and hopefully the problem will not return. I have been flashing a few different ROMs. Because of this I am becoming ever more reliant on the Storage Card for system recovery. So cant afford to have a dodgy one.

Hi, folks.

I use a HTC cruise with WM6.1 from Bepe. This morning, all files from my 8GB miniSD card just vanisehd!!! I removed the card from the phone and tried to access the files in windows with a sd card reader, but no file was seen. Although, there was only 3,5GB free!!! The files weren't there, but they kept occupying space. I used this software to recover the files. Awesome! They were all there, except for the ones stored in root. Also,I had to rename all root folders, the subfolders were OK. I just had to filter files marked as "good" and then copied them to my HD. The phone is working as usual, but I can't explain why exactly this happened? Would it be a vicious virus? A joke from Micro$oft? Any ideas?!?
