All to be flashed using CWM or TWRP. I have always used TWRP 2.7.0.0 and found it very reliable. It has a black holo material theme but if you prefer II have included a Light Material Play theme. Just put the theme folder into TWRP folder in Phone Storage.
[Android General] ivanox1972:
Ii have original u7. Biscuit not loses imei and camera works. What situation is with other rom listed?
[Android General] estuardo4:
tabnabs, thank you very much. You've made life easier for all of us. You said it before, but maybe it is worth repeating: Why do you stopped using Biscuits team ROM and began using Honduras? Is it really more stable? More functional? And between Mlais Honduras and L style? Thank you for your answer.
[Android General] marsian0:
So far, i've only seen two base roms,

1. luftco, mlais, biscuits, ulefone, (the ones from 4PDA), etc

2. nibiru roms

It is possible to flash through CWM/TRWP between roms of the same base without care about losing imeis.

To flash roms from one base to another, you should first flash the rom through SPFlashTools, otherwise, you will end up without imeis/baseband.

If the rom that you want to flash is from the different base, and is in CWM/TWRP format, then first flash any full rom from that base using SPFT, then flash the other one in cwm/twrp.

When i flash with SPFT i always use "firmware upgrade".

hope it helps.
[Android General] ivanox1972:
Helps a lot.

thanks. which one you suggest?
[Android General] marsian0:
I'm in nibiru v3 since more than a week, the battery last longer(3:20 SOT, last through the day ) than in L-Style, and don't have the annoyance of the keyboard repeating keys that Mlais/biscuits have. I think is in the middle between touch accuracy and battery performance. But I haven't tried Honduras, based on Mlais, and that allegedly have fixed touch, and of course much better battery life.

That's my opinion so far, maybe someone that had tried Honduras can tell us about.

New 6.4" phablet in the horizon, but maybe expensive...

http://www.gizchina.com/2015/04/14/letv-s1-s1-pro-and-max-complete-specifications-tables/

[Android General] estuardo4:
I will flash Mlais ROM and Honduras Zip this afternoon. Hopefully that can help me with my dying battery. I'll let you know how touch is. I used to love biscuits ROM, but it is not helping me with my battery. What I really can't understand is why a 4000 mAH battery with a 1920x1200 screen lasts so little. My Xperia Z Ultra had a 3050 mAH battery feeding a 1920x1080 LCD and the screeon on time was more than 5 hours. With my Luftco, my maximum screen on time was 4 hours when I just bought it.

And about that LeTV phone, it looks really good, but as it has a Snapdragon processor, it will be without a doubt an expensive phone. But it is 1.2 cm shorter than the Xperia Z Ultra, almost 1 cm slimmer and 3 mm fatter. That is a good buying point. But my guess is that it will be as expensive as the Xperia at launch ($700 USD).
[Android General] marsian0:
Maybe your battery is damaged if you have let it die, I've heard that li-ion batterys should not be fully discharged. And for the max capacity, they always lie about it.
[Android General] natostanco:
You should always keep liion batteries attached to a source whenever u can, you can try keep the phone shutdown for 1 day and charging but don't think that's gonna help

Anyway before making any claims on battery life you should use greenify and amplify if you don't already and block all the junk and even more
[Android General] estuardo4:
The curious thing is that some people wrote, on another forum, that my battery died because I charged my phone and kept the screen always on using daydream. I guess there is some truth with this, as the phone is always on and the battery is working on the background doing processes. So, you and them are -I guess- right. It is good to charge it any time I can, but always with the screen off.

Alas, the battery is only $12 with free shipping. So I'll order one to check if it is really the battery. But searching on other forums, it seems that it may be a faulty USB connector or a mainboard problem. The cheapest way to know is ordering the battery.

---------- Post added at 01:31 PM ---------- Previous post was at 01:07 PM ----------

Batteries are a great mystery. On one forum they suggested to charge to 100%, remove the battery stats file and use the phone until the battery dies. It was easy because it took 15 minutes to go from 100% to 0% with the screen on. :)

I've heard so many stories, but the reality is that a 4000 mAH battery should last longer. 3 hours of screen on time is not what I had in mind when I purchased the phone. As previously I wrote, the 3050 mAH battery from my Z Ultra was good for 5 hours of screen on time with a 1920x1080 panel. And my Luftco supposedly uses a power friendly processor.
[Android General] tabnabs:
I too am having battery problems which appear to be greater than I first feared when I discovered that I could not charge or connect to pc when the phone is switched on.

I had a spare battery and invested in a battery charger which is slow but does the job. However I have found that battery life is now no longer than a day no matter what rom I flash, and I have tried 5 to date.. It appears that my phone will no longer sleep and that even when the screen is off it is constantly running at 1144. Mhz which is also causing cpu to overheat. So rather than just a faulty USB socket I fear that my problem is more serious.

With regard to battery life, reports on 4PDA for L Style rom are very encouraging. The porter of the rom has posted a screenshot showing only 2% usage after 19 hours.
[Android General] marsian0:
The pboblem with L-Style both (nibiru, 4pda) is that with the screen on, it drains very quickly, no matter what do you do, but in standy it consumes almost nothing.
[Android General] estuardo4:
Indeed. You literally can look at the battery meter and every 50 seconds the percentage goes down one number. No matter if you have the brightness %

I have L-Style installed since yesterday (I didn't installed Honduras as planned, as I downloaded the Zip file two times, and both times the file was corrupted) and, aside that yesterday it went again from 70% to 0% in 15 seconds, I recharged it and the battery graphic is something like this:

------_______

\

\

\

\

\ ------------______

Edit: Well, what do I know. I was trying the camera app (Lenovo Super Camera) and as soon as I started, the phone shuts down. And then I restarted and the battery is now at 3% (from 70% when I started the app). Yesterday was when I started a game. I guess all intensive processor use causes this behavior. I can use the web, read some news, answer emails and use Whatsapp and the battery meter goes down quick, but normal.

I don't really know if it is my battery or the motherboard is shutting down.

Thank you.
[Android General] estuardo4:
Huawei

Now Huawei will have not one, but two large screen phones.

First it was the Mediapad X2 and now it is the P8 Max

http://consumer.huawei.com/minisite/worldwide/p8max/

One is a 7" screen and the other is 6.8" with almost no bezel.

My guess is that it will be more expensive than the Mediapad X2, but not by much. Or even the same price. Looking at the specs, it is difficult to see which is better. The P8 Max is slimmer by 1 cm. But the battery is larger on the X2 (5000mAH vs 4380mAH)

Edit: The price of the P8 Max is way out of my league. It is said to be $585 USD. Not for me. Let's hope the price of the LeTV one is cheaper.

Hopefully some other phones will be out soon.
[Android General] marsian0:
Those are damn fine devices, but way too expensives for my budget.

Since monday night i'm using honduras, no problem with imeis, the touch improved but not so smooth as in nibiru, and after 2 or 3 cycles of charge, the battery life still very poor, i don't know why, with biscuits my battery use to last more than 4 hrs sot, i hope than in a week or two it settles down.

it could be that flashing roms from another bases left something behind, that don't get wiped through normal flashes and affects battery stats?

or our batterys got too worn in the process?

Later i will try a complete format and fresh install with spflash tools if the battery life doesn't improve.
[Android General] estuardo4:
Yes. They are. I haven't seen new 7" phones with Mediatek processors in the $200-$300 range. Nothing from Doogee, Mlais, Tronsmart, Ulefone nor others. Really depressing. But when you compare the price from these Huaweis to the price i can get in my country a smaller screen phone like the Samsung Note 4 or the Nexus 6, then it is indeed a good price. These Huaweis will be (my guess) in the $350-$500 range. The Note or Nexus are at the $700-$900 range at my country.

When I use Flashtools, I always format my devise and then use the "firmware upgrade" option. I don't think that flashing too many times can affect battery life. My guess is that they use a cheap battery to feed our devises. Generic batteries that only last 6 months. I don't see any other explanation. Good thing the replacements are cheap. I'll use a voltmeter to check the energy output of my new battery as soon as it arrive.
[Android General] natostanco:
I do not think the daydream is causing the phone to discharge that much, but probably keeping the phone in daydream allows other apps to not go into sleep properly and continuosly run in background causing the phone to overheat and consume battery and ruin it, anyway I also had problems with battery, also the charger given with the phone is really poor quality, as it was causing the classic high pitched noise when something is wrong, and it also charged the phone slowly compared to a usb connection, the usb cable given with the phone is also poor quality, At least for my ulefone u7.

For me the battery lasts 4 hours full playing videos, I think it is allright. What I also noticed sometime ago is that the schedule poweron&off feature can cause problems in battery readings.
[Android General] estuardo4:
That's exactly what people on the other forum said. And giving that Mediatek devises are at the beginning stages of development, their power management leaves a lot to be desired.

I'm conscious that this is a cheap phone, and the OEM had to cut some corners due to the high quality LCD screen. My USB cable broke at the second week of use and my power supply didn't work out of the box. But, as I said, the screen is great and the faceplate, although is not Gorilla glass, is really strong and scratch resistant. But another cut corner is the battery.

My phone at the beginning also gave me 4 hours of SOT. I miss those days...
[Android General] estuardo4:
tabnabs,

I read your posts on 4PDA. It seems that you discovered that the system's processor is stuck at 1144 MHz when the screen is on and no activity is made. I noticed this too. What I'm going to do is set the processor max speed to 845MHz on the "Performace Control" on the advance settings screen. Just when I read the news in the morning, just to check on the battery drainage.

The thing here is that Mediatek processors does not like to be tinkered, but let's see if I get something from it.

Edit: I lowered the MHz of my processor to 845MHz max. My phone run really slow and it is still consuming a lot of battery. And when I restarted the phone, the max processor speed returned to 1800MHz. As I said, Mediatek's processor doesn't like to be tinkered.
[Android General] marsian0:
hello everybody

last weekend i did an experiment regarding batterys.

i took my wifes's ulefon battery at 97% and inserted in mine, deleted battery stats and reboot. Acording to GSAM Battery the statistics were identical than my battery, so after a few hours of playing with the phone, not so heavy, the battery was at 19%. So i decided to switch back to my battery. When i inserted the battery at my wife's phon, it show the battery was at 54%, quite a difference.

My wife's phone it's been with mlais biscuits since months ago.

My conclusión is that nibiru rom expect to see a shorter capacity battery, and even when there are stiil juice on, it simply appear that is not.
[Android General] estuardo4:
I'm no battery expert, but isn't Android system the one responsible of the battery's stats? There are double capacity batteries that can be inserted to a lot of brands and each one accurately notice the larger capacity on the battery and adjust their measurements. Maybe that is not the case with Mediatek devises. I wouldn't be surprised, as many functions that I was used to tweak are not tweakable here. And the IMEIs and the NVRAM handling . What a mess!

On other thoughts, looking at the hands-on videos of the announced P8Max from Huawei, it seems that the bezels are not as small as they want us to believe. They show it as a bezeless phone, but in reality you can see a 2 or 3 mm black bezel on each side.
[Android General] marsian0:
i did some research, and guess that maybe the power profiles are different in both roms (nibiru and mlais), so in nibiru the drain values are rated higher, so the difference in battery estimates.

maybe somebody can see if there are differences in power_profile.xml (which is inside /system/framework/framework-res.apk) between those roms.

this apk have to be decompiled to see the content of xml file, and i don't have the proper set up to do it.

i got this idea from user on 4pda who commented about power profiles.
[Android General] marsian0:
power profiles

attached profiles for biscuits and L-Style V2, huge difference in drain values, altough biscuits values are set too low. Next thing i will try to compile apk and swap xml from Biscuits to NibiruM1-3 which i currently have, if this works, later will swap it to LStyle... we will see...
[Android General] ivanox1972:
I need help... I think I have some low level virus, probably root file, so I do not want to re install from recovery but erase and format all..

I want to reinstall U7 on stock firmware, same to be as just came from store.

How to do this- with which program, to us which firmware file?

thanks
[Android General] estuardo4:
Wow, they are very different indeed. It would be a good idea to check vanilla power settings for Nibiru and for Ulefone/Mlais

It is a shame these models are not popular under the tinkering community. You can see that we are avid for an expert, as responses for posts from sampei , tabnabs and you are what keep this thread moving and hopeful.
[Android General] marsian0:
what i did was pull the power_profile.xml from framework_res.apk from biscuits rom, and replace the file in the corresponding apk of L-Style rom, using 7zip.

Flashed the rom, it boots ok, it appears that the drain is lower, but i haven't had enough time to play with it and calibrate battery.

Once i had calibrated my battery and get the readings i will let you know.
[Android General] tabnabs:
As you probably are aware I have been having battery problems as my phone will not charge when switched on. I am taking battery out and using a cheap Chinese battery charger.

As Estuardo commented I noticed that the phone was not sleeping in any rom I was running. In fact when the screen is off it appears to be running at a constant 1144. Mhz. So I thought that there was more than a battery problem.

I therefore decided to start from scratch.

I Flashed the Mlais M81 stock rom using SP Flash tools and then flashed the latest L Style Rom from 4PDA with TWRP:

https://yadi.sk/d/K33Yt48ag64hS

The phone still seems to be running at 1144 Mhz when the screen is off but I am now experiencing better screen times ie around 4 hours or more.

From fresh battery inserted today the phone has been on for almost 9 hours is currently at 38% remaining with 31% screen time clocking in at 3 hours and 37 minutes.

What has changed I don't know. I will keep monitoring screen on performance.
[Android General] tabnabs:
Having frozen Gmail, Google launcher and the Google app, I uninstalled system server 1.4.5 which seemed to be causing multiple wakelocks, sometimes into thousands. I then activated Greenify and did the necessary with other troublesome apps.

Currently battery remaining stands at 44% with 4 hours and 15 minutes of screen on time so far.
[Android General] marsian0:
After struggling with power profiles between differents roms, the results were unsatisfactory, so i went back to nibiru m1 rom, which so far is the one that give me better battery times.

tabnabs, could you describe the procedure you did to get more than 4 hrs of Screen On Time? do you use an external charger ?

i would like to try your suggestion, but i don't think i will pull out the battery just to charge it externally.
[Android General] tabnabs:
I am in a position where I either have to switch off the phone to charge it or pull the battery and replace with a charged one. So yes I do use an external charger which can be purchased from China for about £1 sterling. I have noticed that the externally charged battery does appear to discharge much more slowly from a full charge. So whether the phone itself can actually achieve a 100% charge is questionable.

My procedure was as follows.

1. Took the ebrs from mlais stock rom, because they give a system size of 1gb, and used ebr tweak to increase internal storage to 6gb.

2.Replaced amended ebrs and TWRP into mlais rom and flashed using upgrade in SP flash tool.

3.Flashed latest L style rom and supersu zip and installed my apps from titanium as normal.

4.Installed wakelock detector and let the phone run normally for 24 hours.

5.Installed Xposed framework and Greenify.

6.Checked wakelock to find out which were the troublesome apps. I discovered that there is an app System Server 1.4.5 which was causing multiple wakelocks, into the 000s, so used titanium to uninstall it. I don't use Gmail, Google app or Google launcher so froze them.

7.Then used Greenify to tidy up the other troublesome apps.

The procedure appears to work producing screen on times well in excess of 4 hours.

Whether this is due to the external charging of the battery improving overall battery life I can't say. However it appears to work for me.

The one thing that does not appear to be able to be achhieved is to make the phone sleep. When the screen is off it still constantly runs a 1144 Mhz.

In fact the phone only appears to run in 3 states. Maximum, minimum or 1144 Mhz.

I am currently typing this with 92% remaining and with 1 hour 35 minutes of screen on time already.

Help me with a new battery

Hello,

I've already ordered a replacement battery from two different places (one in the US and one in China). Both listed it as "in stock" and willingly charged my credit card. The first one was clear to inform me that the battery was out of stock and refunded my money the same day. Then I decided to order from chinavasion.com and, after a week and after I sent an email asking for why they haven't shipped my battery yet, they inform me that they will have it in stock on May 11th (that was on April 18th). I decided to wait because I was able to still use my phone. But at the beginning of May the battery completely died and I was not able to use it anymore. Then today chinavasion.com informed me that they still don't have a time frame to receive my battery, so I canceled the order.

I was searching other places (geekbuying.com, tinydeal.com, etc) and none have them on stock (or even listed).

I've already switched to an old phone for now, but I need the battery to be able to sell the phone, as I need that money to be able to afford one of the newer ones.

Do any of you have recently bought a replacement battery? if yes, from what company? Do any of you have a spare one willing to sell it to me (it doesn't matter if it's used)?

Thank you for your help.
[Android General] natostanco:
Get it from aliexpress or dhgate, there are quite a few sellers there
[Android General] estuardo4:
Thank you. Unfortunately none of the stores listed the battery as "on stock" and the three that supposedly have it, they are reported by users as deceiving their clients saying they have products in stock when in reality they don't.

But I ordered from one anyway, so let's hope they really have it.

But if anyone have a spare one, I'll rather buy it from you.

EDIT: Unfortunately the store I ordered didn't have it in stock. I've been without my phone for more than a month. I can't find a substitute (The Huawei Mediapad X2 is more money than I can pay). No substitute and no battery. What a shame.

"ulefone u7 battery", "ulefone u69 battery"

there are sellers with good reputation.

how does one install the twrp? i am rejoining using this device after almost 3months and everything seems a blur...lol..cannot remember

trying to download some of the new roms like the vibe rom which (at least this much I recall) was very smooth except for a call problem (yes basic issue) but they have a new version out now on the n1 forums

seems a lot has happened in past 3 months

thanks (anyone)

EDIT

got the phone going...vibe rom does not install, color os just keeps indefinitely churning while booting up

am on n1 yun os ver 60 from 3/25

n1 vibe rom was most impressive had the right balance of speed and built in functions (screenshot etc) but had a call issue

new version of vibe rom..no idea yet

philz recovery works great so am on that

twrp is too fickle from my experiences..note 2 backup restores do not work..same on tab pro depending upon version (latest not always greatest)
[Android General] mac231us:
the miui does not recognize sim..unlike other roms (after flashing from sptools the n1 base...maybe need mlais base as sdcards are switched in the miui?)

vibe ui symlink issue can't figure it out something in updater script

EDIT using luftco 6/16 as base (is now rootable using vroot was not the case last summer..it has been a year now!), miui recognizes sim card
