Kernel: UV and BLX

Hello,

new kernel!

Features:

* UV Undervolt (not new, same as in last kernel)

* BLX Battery Life eXtender (Credits to Ezekeel) see http://xdaforums.com/nexus-s/development/mod-battery-life-extender-blx-t1257497

BLX in short:

* You use Performance Control Tool, on Page Akku information you choose for example 95%

* Battery will load to 95% and then stop charging

** Variant 1 will jump to 100% (visual)

** Variant 2 will just stay at 95%

-> your battery will never charge fully, that is proven to extend battery life

To change the maximum charge value you have to reboot to see the correct percentage (after changing the 80% in Performance Control to 90% for example) if you are using variant 1.

The best value is chosen so that you can last a day (something between 80% and 95%)

Because our device charges the battery real high (as seen in battery driver) i would really recommend to use this feature. The voltage curve if set to 95% goes still up to 4250 mV which is higher than the recommended 4.2 V maximum Voltage for Li-Ion. I know we have a 4.35V maximum charging "high voltage" battery so that doesnt mean the device is killing the battery instantly but i want to use my device for 2 years without changing the fixed battery.

See this for background: http://www.powerstream.com/lithuim-ion-charge-voltage.htm

Link for Performance control tool:

http://xdaforums.com/showthread.php?t=2401988

Kernel download:

Version 1: jumps to 100% if limit is reached

http://d-h.st/5xF

Version 2: stays at configured maximum

http://d-h.st/vKm

I recommend version 2 so you can see all works as expected and you'll not see wrong values. And i recommend using 95%, maybe 90% if your battery lasts long enough for you.

Have fun and a long battery life ;)

Help needed

Hey guys,

I've got quite a bit of a problem here. I was checking my facebook on my phone, and opened a vid there, when my phone froze, and rebooted itsself and got into a bootloop. I then reset the device to CWM by using

volume + and power key for 12 secs. Wiped cache and Dalvik. Then I hit 'reboot device now' and it went down. It's not starting up anymore, resetting again doesnt work, and in SP flash tool it isnt recognized either.

The blue light flashed on if plugged into the wall charger or pc usb port, but nothing from that point..

any help on this? I really need my phone :')
[Miscellaneous Android Development] Timmmmaaahh!:
Hey, that really suits your username ;)

Eh.. I had a similar issue with a Sony Xperia GO before, I just left it charging all night and it started the next morning. Otherwise.. warranty?

ROM Update 1.0 / Kernel 4.10

Features

* installs busybox

* enables usage of EPO (update period 3 days)

* DISABLES USAGE OF AGPS ON ROAMING (it is enabled by default)

* switches HEADSET button from start/pause to next song (only works if playing/player was started once, depends on player)

* installs my kernel, latest version with

** battery life saver (variant to stop charging at 95% and display stays at 95%)

** undervolt

** logging cleanup

* enables init.d support

** including init.d script to set maximum charge to 95%

You can disable features by editing the zip file:

* to not change media-key delete system/usr/keylayout

* to not use battery life saver delete system/etc/init.d/00_BLX

* to change battery life saver setting edit system/etc/init.d/00_BLX

* to use agps on roaming delete system/etc/agps_profiles_conf.xml

* to not use epo delete system/etc/epo_conf.xml

This has to be done prior to flashing the update pack. But you can revert/change with flashing FixPack-B.zip from Kitkat update and then flash again the update pack.

EPO seems to work great for me - AGPS is enabled anyway, so it has great impact if you are roaming (and dont want to use agps due to roaming fees). EPO is updated if you have wlan or data connection on and just use gps.

Flashed testkernel 6.3. Higher AnTuTu points reached. Almost 18000! As I noticed, because of storage I/O point increased noticable.
[Miscellaneous Android Development] hackwerk:
With custom kernel 6.3 , I get a 17.738 in AnTuTu 5.3 (@Freec1: All values are very similar, only your RAM Speed is much higher!?)

2 problems left for me:

1) Some apps won't update or install. They seem to be fine, but when starting they crash, or complain about space (enough?!) and disappear forever. A reinstall (or deinstall & fresh reinstall!) is needed PLUS immediate reboot, and it is fine?! Is this because of Link2D icw KitKat?!

2) Boot images and animations will not install anymore via ZIP in CWM (they did in JB)?!

Dismantle AcerE3 UK

My USB port was playing up and was not charging the phone properly so i decided to take it apart. Took a few pictures of the process.

First screw located by the microSD slot

Second is buy the MicroSIM slot

I used a plastic card to pries it open

After a few mins, finally got it open

View of the Board(as you can see sand managed to get into the phone)

Picture of the battery, 3.8v 2000mAh 7.60Wh

Closer view of battery Connection. You can see some sort of comms connections, there are more under the metal sticker that is around the button.

After unscrewing the speaker unit from the bottom of the phone, i proceeded to pry the battery off with a plastic card.

Battery off.

Close up view of the USB Port

Unfortunately i couldn't see anything wrong(physically) with the connector decided to give the internals a clean and put it back together. USB is still playing up, So ive ordered a universal QI Wireless charging kit and im planning to wire it up in a couple of days when it arrives.

also Ive uploaded a copy of the uk Firmware for KitKat. It as been modified to allow it to be flashed by CWM.

Thanks for your guide & photos!

I hope to replace my broken screen soon (at last), with this one or this one or this one (less reliable shop).

I cannot do this myself I think, or can I?! If not, I will go to a small telecomshop here in Amsterdam.
[Miscellaneous Android Development] Di@mond:
Your welcome guys :D

When my equipment comes ill take some more pics for you. The silver thing under he battery seems to me like the rear of the LCD screen. and the motherboard is on top of it(there are 4 screws holding the board down).

I shall have a closer look at how the touchsceen may be removed.

(only just realized the the battery is a Samsung brand)

titanium backup

Has anyone managed to get Titanium Backup working after rooting?

Each time i want to restore or backup an app it gets stuck in a loop, or am i the only one with that problem?
[Miscellaneous Android Development] hackwerk:
Dont know, but why still use Titanium?

In Google Play store you can automatically restore all your Apps, every time, on all devices (if backup is on in Settings), and a good complete backup is done with our beloved CWM Recovery right?

Ps. Are you making new backups with it (from KitKat), or trying to retrieve old backups to a new OS (from JB to KK etc)?!
[Miscellaneous Android Development] hundz:
I've been using Titanium Backup since my first Android phone and never really cared much about other alternatives, as far as i know it's not possible to restore apps with previously used data in the google store backup option.

I also got a bunch of apps which aren't available on the google play store.

And i was trying to restore my apps from my previous device, not from another OS. (Bought my Acer Liquid 2 days ago)
[Miscellaneous Android Development] Shreps:
Try to use internal memory for your backup, there is maybe some restrictions with ext sd

Envoyé de mon One+
[Miscellaneous Android Development] hackwerk:
I am not really familiar with Titanium but I read 2 things everywhere when **** hits the fan;

1) Dont use SD/external storage for backup/restore etc;

2) Only use the Standard Android installation way in it, and NOT the Hypershell Installation way.
[Miscellaneous Android Development] hundz:
Thanks guys, that didn't help though.

Found the solution meanwhile, I had to disable the option "Mount namespace seperation" in the SuperSu settings. Now everything works like a charm.

Anyway, got another question, each time i want to exit the recovery I'm getting a warning "Root access possibly lost. Fix?"

No matter what i choose, nothing changes and I'm getting the warning every time I'm leaving the recovery, any way to prevent that?

I also didn't delete ".. recovery .." in the system folder because i have no file named like that, maybe that's the reason?

Can anyone help me with rooting of E380? I've tried to follow instructions from the first post, as well as from other links. As drivers, I've used the PDANet. Everything looks fine until step 4 - simply nothing happens when I connect the phone after I set up ST Flash Tool and press Download. First of all, SP Flash Tool complains that not all the components have been read which may cause a bootloop (it highlites the first line red, "Preloader" if I remember it well) and then keeps "searching" for the phone and that's all. The phone is visible to the system (Win XP). The phone is a dual-sim E3 updated to KitKat. Can anyone help (may be by private message)?

You have to connect your phone AFTER pressing Download (when it is searching) and the phone needs to be OFF.

If still no luck, PM me or ask in Q&A thread, not here plz.

Upgrading to new SD

OFFTOPIC:

I want to upgrade to a(nother) new SD, because my current SD is stuttering and CRC-erroring sometimes.

When Googling everyone says just to copy-paste the contents to PC and back to the new SD.

That seems a very scary method to me, thinking about ext4 (my card was formatted in CWM) vs FAT(32), Link2SD which moved all my Apps, hidden files, CRC-errors etc. etc.

How should I format the new 16GB card (FS, sizes, swap?) and where (in Android, in CWM, in WIndows (which program))?!

How should I copy the current content (CWM backup, Windows Explorer, ...)?
[Miscellaneous Android Development] Di@mond:
There are a few software available that will allow you to clone your SD card to your new one. I'm on my phone ATM so I can't help you any further. Just google "clone SD card", it will bring up some results as well as some instructions on YouTube on how to do it.

Edit: Try this tool.

http://hddguru.com/software/HDD-Raw-Copy-Tool/

Then resize your partition with partition magic (or some other software that will do the job) to utilise the extra space.

[Miscellaneous Android Development] hackwerk:
Everyone still alive? Hope yall had a great Xmas and NYE! Hopin for a lot of custom kernels and maybe ROMs this 2015!

If you are an experienced user, please now and then check the seperate Q&A Subthread (see tab on top of this topic), and try to help your fellow users out of misery! :good:

Ps. My device is running Init.d scripts (had to create folder /etc/init.d) now, is this standard in our (KitKat)(now), or is this due to the fact I use our (only) custom kernel now?

Ps2. Still have to put my new SD in, but should/can we use swap and if so how big should the partition be? I know how it was in the days, but what is the best part layout for our custom KitKat device now (16GB SD)??
[Miscellaneous Android Development] nikagl:
Hi hackwerk,

Haven't used my E380 in a while, so not too active on the E380 threads. I have asked in the Q&A thread which issues are still active so we can help them out of their misery :)

I doubt init.d would be available in a stock ROM. Usualy it's part of the kernel (afaik) so I guess it must be your custom kernel.

I mostly format my SD in the device and take the partition as the device likes it - no experience with that here. My only experience is that 64 GB cards do not (still) work in most of our devices.

Regards,

Nika.
[Miscellaneous Android Development] paugustin:
Hi, I have to disagree on the 64Gb card... I have one and it works in ALL my Acer devices for some time now. I don't remember when I bought it but it's been at least a couple of year.
[Miscellaneous Android Development] Antagonist42:
Working SDCards depends on a mixture of things...

Firstly, Class 10 (I think that's right) has had the biggest problems with not working in a few devices, not just Acer,

Secondly, since partition info is using GPT/GUID the internal memory (NAND chip) doesn't have to be FAT32 format as it used to be on a lot of devices, to satisfy the partition information (that's what I've been able to make out from what I've been doing and reading).

Thrice could be a charm.... It also depends what partition type formats are implemented in the whole system, as I found out, my Acer Tab wouldn't read FAT32 and formatted it to ext4, even though the system can read/write larger files than the 4Gb limit of the others it reads the whole 64Gb and writes to it.

It may be useful, if it's correct? ....to use exfat tools, if I read it correctly, copy them onto your SDCard and the system should be able to use as normal, files of 4Gb and larger....this is all dependent on what is actually implemented by Acer! ...

Hope this helps a little ;)
[Miscellaneous Android Development] nikagl:
Very good to know! I have tried 2 brands in several Acer devices. Where they worked in the Samsung Galaxy Tab 2 (with CM11), they didn't in my Acer devices. One of them was a MicroSD XC C10 from Delkin Devices and the other was a SanDisk Ultra MicrSD XC I. Looks like both are Class 10 chips...didn't spend too much time though, so shall do some more testing as soon as I have time :)
[Miscellaneous Android Development] Adge40:
I'm waiting on custom roms,I've only found three,the galaxy note3 rom for e380,the androium4 rom on the previous page and a dreadful miui5 rom,the note3 rom was buttery smooth but had many issues(apps not working etc) and was on 4.2.2. So I went back to androium(only a few minor issues(settings very laggy))as for whatever reason is the only kitkat rom/firmware that allows use of my sd card(maybe something to do with the previous two posts??)looking forward(hopefully) to something like cm or slimkat
[Miscellaneous Android Development] hackwerk:
Officially Acer (E380) only supports up to MicroSD SDHC 32GB (to the maximum Class 10), as you can read in the manual (page 53).

I think this has nothing to do with the size, but more with the SD specifications. It supports the old SD, and SDHC (which is up to 32GB) but NOT SDXC (which uses a lot of newer features etc).

Ps. Still no answer, which nowadays (!) is the best number of, sizes of and file types of partitions on an SD (16GB, and 32GB)??
[Miscellaneous Android Development] Antagonist42:
That's an open-ended question!

What is the Disks intended purpose?

What partition types is your system capable of reading?

Will it be removed and used on a totally different system and partition types?

Will it be used on Linux or Windows?

If Windows, will software need to be able to read/mount the partition?

It's trial and error as to what you're doing and how.
[Miscellaneous Android Development] cyclon1978:
a) I added init.d support to kernel.

b) swap will give us more ram - i doubt you'll ever need more than 2 GB. On 1 GB devices i usually add ZRAM to buy ram for cpu speed without the other negative effects of swap. swap will cost speed, cause lags and wears out sd card.

Andreas

A normal start after flashing the kernel is slower but the second reboot should be at normal speed (or better than stock due to smaller kernel size).

What a shocking surprise:

Changing my (old) Transcend 16GB Class 10 SD to my brand new Samsung EVO 16GB Class10 SD made a major difference. It is WORSE! :mad:

Slower immediately, and AnTuTu shows it: I drop from 17.836 to 15.541?! This is mainly because of a BIG difference in Storage I/O: 2554 (Transcend) to 644 (Samsung)!? :confused:

Made an exact copy with HDD Raw Copy.

Bizar...
[Miscellaneous Android Development] nikagl:
Interesting. The Samsung is supposedly 2x faster than the Transcend (based on the models I can find at hardware.info). Can you compare it in a normal PC? Wonder what it does when copying a 10 GB file onto it (and from it back to the PC again)... Nevertheless, not really something for this thread unless it turns out it's the other way around in the PC which proves it's caused by the device (in which case I wouldn't know where to help either :D) ;)
[Miscellaneous Android Development] nikagl:
Hi all,

I started testing my " SanDisk Ultra MicrSD XC I" in my Acer A1-811 tab. It has a KK ROM (Acer_AV0K0_A1-911_1.025_WW_GEN1 / RV02RC06). Once in a while it's telling me the SD Card has been removed. Guess that's the "known issues" with Class 10 SDcards?

Regards,

Nika.
[Miscellaneous Android Development] hackwerk:
Yes, this is commonly known as the "Unexpectedly removed" problem.

The brands Samsung (phone) and Sandisk (SD) are mentioned an awfull lot.

It seems to one of the following though;

1) Corrupt card / files / partition (table);

2) Due to an major upgrade/change of OS version without reformatting;

3) The hardware (SD from Sandisk (with phones from Samsung))!

Solutions:

1) Repartition & reformat (IN A PC (MiniTool))(to another file system, i.e. exFAT instead of FAT32);

2) Use a new/other SD, NOT from Sandisk, and Class 4 or lower (higer classes like Class 10 tend to have low Random Access Times);

3) Return SD in warranty and get a new one (lifetime warranty?).
[Miscellaneous Android Development] nikagl:
Formatted it with SDFormatterv4 to exFAT (with ext2/3/4 you need additional tools to read the files when mounting in the pc)... will post results whenever I have them.

[MENTION=2205551]paugustin[/MENTION], you never had these issues with your 64 GB cards? Possibly you had never formatted the cards in the device (which is a default procedure I do) and they're still exFAT which many of them are when coming from the factory if I read correctly :)
