I'm sharing my 2 custom recovery and boot files.

https://copy.com/Ln2n8mCrGxQVbwUa for custom recovery

https://copy.com/HFhrnYASXWBXEJ3Q for custom boot file

I hope they are useful for you.

Also, please install and test this utility. It may help you with your screen sensibility issues. I installed on mine and I can now write better handwritten notes (but it may be a placebo effect, that's why I need you to help me testing)

http://xdaforums.com/showthread.php?t=1261237
[Android General] aaallleeennn:
I don't know if it's placebo but I feel improvement, really. Do you use this rom from team biscuit, does it have bugs? And can you point me to installation guide, i found russian site but can't translate it with google:rolleyes: i need that guide step by step to prevent loosing imei's
[Android General] estuardo4:
I also see improvement using this app. Both using the on screen keyboard and writing notes.

I didn't lose IMEIs when I installed this zip, because my kernel base is made by Luftco. If your kernel is other than Luftco, I cannot warant your IMEIs. I always loose my IMEIs when I try to flash zips made for Nibiru and Mlais, but never when I flash zips made for Luftco phones.

And about bugs, I haven't found any. Not even FC or some other problems. YMMV
[Android General] aaallleeennn:
So far this rom is great, without any bugs. I've flashed it with cwm, imei's are ok even if my phone isn't a-one x, it's ulefone u69. I see big improvement in touchscreen responsiveness. Only problem is that I don't understand those chinese apps :D:D:D and so I don't know how to set anything in mtk tweak app :D:D
[Android General] estuardo4:
Take a look at this page:

http://en.miui.com/thread-22930-1-1.html

What I did was to install the English version and look at the options, then apply them on the Chinese version. Any version that you use will stick.

Try it, you will thank me later :)
[Android General] aaallleeennn:
I'm sorry for bothering you mate, but i can't install eng version and i can't put app in system/app folder, every time it says failed. Don't know why :( i tried mount r/w in root explorer but it doesn't help. I tried root explorer also but nothing. Can you post screenshots of what you have selected in mtktweak to increase battery life? Thanks :)

P.S. do you only use mtktweak app and you get 16 hours of screen time, or you have some other apps or tweaks?
[Android General] estuardo4:
Don't worry, I don't have the English version installed, just the Chinese version. But I can tell you this:

1. First Option is the Performance/Battery option. There are 7 options. The first three are for performance, being the top one the fastest. The fourth is the "no changes" option and the last three are battery savings options.

2. The second is something related to the installed RAM memory and tweaks. For MTK6592 processors, the developer recommends the second from last (2G).

3. For the other three options, the first and third option are self explained on the names (Logcat and ZipAlign, being the second option the one that I don't remember, but I have it switched on). There's a new MTKTweak V15 translated that I will test.
[Android General] ivanox1972:
phone is here, but where to start- I have many questions and support is not big...

1. as I saw until now, all is working except proximity sensor. Do u7 have it? screen is not switch of when phone call near to head...

2. is anywhere to buy silicon case, I hate those cases with window...

3. It came with 4.4.2 preinstalled, software is samsung without some options (excellent solution!!!), I just want to root not do any custom firmware at first... how to root?

4. I put out screen protector which was already on it/ to increase sensitivity and screen qualityexperiance (SCREEN IS GREAT!!!). As I know, no gorilla glass, so I must be careful for scratches...

probably I willl have more Q, this is for start (I was on note1, mega 6.3, note 3- very big support). Android 5 will bi very nice, device has big potentials just to polish few things...

thanks in advance Ivan
[Android General] aaallleeennn:
1. yes it has proximity sensor, open antutu and see in specifications which sensors it has.

2. so far i haven't seen silicone case for this phone

3. first of all i recommend you to connect phone to pc and let it install drivers, download mtk droid tools and make backup before you do anything to your phone. You can root it with vroot (i think now it's called iroot) via pc or you can download mobile app from their site and install it and let it root your phone (i did it with mobile app).

You can also install recovery with mtk droid tools, and flash custom rom. I'm using one from team biscuit it's 4.4.3 and has many optimizations without bugs. Battery duration is great on this rom, and i have also put some additional build.prop tweaks. And screen sensitivity is improved in this rom.
[Android General] ivanox1972:
Thanks friend. Where to find this biscuit team rom/ support site/ forum... I want to know is this luftco rom has same interface meni settings as u7 or totally different,
[Android General] aaallleeennn:
http://www.luftco.cn/bbs/forum.php?mod=viewthread&tid=43666&extra=page=1

It is in chinese, use google translate. I think that interface is the same.

And don't forget to make backup prior to any flashing and also make imei backup.
[Android General] ivanox1972:
Can not root. This iroot said successful; but in fact no root access. It is stock 4.4.2
[Android General] aaallleeennn:
With mobile app or via pc? Connect your phone to pc, open mtk droid tools and see what color is square in left bottom corner. If it's green then you have root, if it's orange then click on Root button and let it finish root, but if it's red then find vroot on google and try to root with it.
[Android General] estuardo4:
1. I don't have a working proximity sensor. Engineering menu says I have it, but it's not working. It's not a big deal for me, as I never use the phone near my face. I use a bluetooth thingy (SBH52) from Sony (a must for every big screen phone).

2. I have mine without a case for five months now, No need for protection yet.

3. As Alien wrote, you need a PC running VRoot. It is the only way that I have found to do it, as both Framaroot and Vrot apk don't work.

4. I've been using it without the screen protector and put it on my pocket daily and no scratches whatsoever. Not one. It is not Gorilla, but it is really sturdy (at least for me)

There are a lot of other ROMs to try, but, as with all Mediatek products, you have the possibility of losing your IMEIs if you flash a ROM not intended for your phone. They may look similar, but all brands are different. YMMV
[Android General] aaallleeennn:
Did you tried mtktweak v15??
[Android General] estuardo4:
I tried V15 untranslated about two months ago. Frankly, I don't see a difference and I prefer to use V14 that is included with the biscuits team ROM.

I tried to use another method to recover my IMEI rhis weekend, without success. I saw a post on a chinese forum saying that I need to copy all contents of the MD folder at nvram and rename it md2, but it didnt work. Oh well.
[Android General] aaallleeennn:
Have you tried method with engineering mode where you enter your imei's?
[Android General] estuardo4:
This is what I've tried so far:

1. Engineering Mode. Both on the phone options and the GPRS options. On the phone option, where you use AT commands, without space after the AT command it gives me an error saying "command not valid". Placing a space after the AT command, it gives me error "Not build option" or something like that.

2. Restore a backup nvram using MTKdroid tools. I have a green box, meaning I have a rooted phone. When I try to update, an error says "tppy command not found" or something like that. I tried the same with the phone in recovery mode. No errors, but still no IMEIs after a reboot.

3. Write IMEIs using MTKDroid tools. All seems fine, no errors, but also no IMEIs after a reboot.

4. Using the IMEI.exe program I made a file MP0B_001 to replace the /data/nvram/md/NVRAM/NVD_IMEI IMEI one, changed permisions and after reboot still not valid IMEIs.

5. Made an nvram backup folder, tried to replace the one at /data/nvram/. Changed permisions and nothing happens.

6. Flashed original ROMs from Luftco, Nibiru and Mlais, one with "preloader" checked, and another time with "preloader" unchecked, using SP Tools. With both methods I have working IMEIs with the Luftco ROM, and working IMEIs after I flash the zip fro team biscuits. With both Nibiru and Mlais, I have null IMEIs, but I can recover them using MTKdroid Tools. Then I flash the zip from Team Biscuits and I still have working IMEIs . The problem is when I try to flash a zip ROM other than Team Biscuits. I have unrecoverable IMEIs. It happens with ten different ROMs that I've tried.

7. On the Nibiru forum, they advise to make a copy of the /data/nvram/md folder and name it md2 and change permisions. Unfortunately, no working IMEIs.

As you can see, I've tried all the methods I have found on the web with no luck. The curious thing is that I have working IMEIs on a zip ROM other than Team Biscuits, but this ROM formatted the internal partition as 1GB/15GB for internal/phone storage. Then, in all my wisdom, I flashed EBR files to format the partition as 8GB/8GB, unchecked everything else and flashed. As a result, I had the partitions I wanted, but on the process I lost my IMEIs and since then, I haven't recovered them when I flash a ROM using a zip file on Recovery. I only have working IMEIs from factory ROMs and with Team Biscuits zip ROM.

I don't know what I did wrong, but I've spent too many hours trying to have a working phone. Too many wasted hours. I really don't know why Mediatek place the nvram data on the /data partition.

Anyway, I hope this email helps other people to learn that falshing ROMs is no picnic with Mediatek processors.
[Android General] aaallleeennn:
I can't believe that neither one of those methods works :( some people don't have problems at all but some can't do nothing on their phones.. Which rom is good to try beside this from team biscuit? Are there deodexed roms for our phone?
[Android General] estuardo4:
When I flashed the EBR files I somehow messed up my nvram folder. I wish I knew how to get it back. Doing factory restore has not helped me. It seems that there's a method that involves opening up the phone to reach for checking points, but I won't go there.

I haven't found deodexed ROMs. In fact, the only other ROMs I have found are from Chinese developers porting UIs from other phones. But they don't even optimize the features. As long as the phone boots, it's OK for them. No custom ROMs, no AOSP ROMs, nothing.

But hey, at least there is some movement.
[Android General] aaallleeennn:
yeah, I hope for CM soon :D but this rom from team biscuit is also very good with a lot of optimizations :)
[Android General] estuardo4:
Yeah, it is great, but I'm always craving for more. Overcloacking, different governors, kernel teakings, etc. Things that only high level developers can create. I haven't found xda-developers' skill levels on any chinese forum. But I'll keep watching, as a 7" screen phone is what I want, and no other vendors aside of China are doing it (with higher end specs).
[Android General] aaallleeennn:
Yeah kernel tweaking and oc would be great :D but most important thing for me is to make battery last longer, i don't need that much high performance since i don't play games or do anything that requires my phone to be super fast :D

Hey, if you want build.prop tweaks that make 3g faster just tell me and I'll post it. I know there are many tweaks but I have tried these and tested 3g speed and it's 300% faster.
[Android General] Axelman8:
Prop tweaks?

Yes please ;)

Regards

Axelman
[Android General] aaallleeennn:
First test your current 3g speed so you can see if it works, I have improvement of 300% in download and upload speed but all depends of your providers max speeds. Add these to your build.prop:

ro.ril.hsxpa=5

ro.ril.hsdpa.category=28

ro.ril.hsupa.category=7

ro.ril.gprsclass=34

net.tcp.buffersize.default=4096,87380,256960,4096,16384,256960

net.tcp.buffersize.wifi=4096,87380,256960,4096,16384,256960

net.tcp.buffersize.umts=4096,87380,256960,4096,16384,256960

net.tcp.buffersize.gprs=4096,87380,256960,4096,16384,256960

net.tcp.buffersize.edge=4096,87380,256960,4096,16384,256960

net.tcp.buffersize.lte=4096,87380,256960,4096,16384,256960

net.tcp.buffersize.evdo_b=6144,87380,1048576,6144,87380,1048576

net.tcp.buffersize.hspa=6144,87380,524288,6144,16384,262144

net.tcp.buffersize.hsdpa=6144,87380,1048576,6144,87380,1048576

Save build.prop. Restart your phone and test 3g again. Let me know if it works.

P.S. just to know there is actual no space in above number 16384 but in every forum when you write this it automatically adds space, so delete it after you paste this into build.prop

Hi,

I'm one of the first owner of U7 (U69) and flashed Biscuit Team 4.4.3 ROM with cwm without loosing IMEI. It is a great ROM but I've found a problem with Lenovo Super Camera v3.6.7 : setting recorded video to full HD (1920x1080) give a wrong aspect ratio both on preview and recorded file. Also the preview in full HD is not full screen as it was with original firmware.

So I'm forced to use the stock camera app to recond video in full HD.

Please, can anyone with Biscuit Team ROM try to record full HD video with Lenovo Super Camera v3.6.7 ?

You can find the link on this forum.

Thank you.

Best regards,

cdr
[Android General] estuardo4:
Hello, I did'n find the version you wanted, but I tried with the latest version posted on xda-developers (4.1.13) and it can record at 1920x1080 at 30fps with my phone. I'm using Team Biscuits ROM. No problems here. Thank you for the apk recommendation.

Can I downgrade stock 4.4 to stock 4.2 and root it?
[Android General] cdr400:
Thank you for trying it.

I'm using 3.6.7 Pro version of Lenovo Super Camera as 4.0 Pro version doesn't work on my U7. Pro version has many professional settings that are missing on other version.

Also the first "lite" version 4.1.1 was missing setting for recording resolution and was giving a 480p only video.

However the last "lite" version 4.1.13, as you pointed out, has setting for recording resolution and finally give a perfect video at 1920x1088@30fps :) Thank you for finding it.

Best regards,

cdr
[Android General] estuardo4:
Yes, you can, using SP Tools and Framaroot for 4.2.2. I did it a lot of times. Just make sure you remove your SD Card and backup whatever you may have on your phone memory prior to doing it. I once lost the contents of both when I downgrade the stock ROM. I downgraded it about 5 times and only in one of them lost the contents. But I lost them, so it is better to be safe than sorry.
[Android General] ivanox1972:
Ok, so it is not dangerous?

I still not have anything important on phone.

I will download sp and ulefone firmware (640MB) from official site, this is 4.2.2 isn't it?

then, I can root easily and put recovery and custom rom?
[Android General] estuardo4:
I haven't seen lately custom ROMs for 4.2.2 so I can't help you there. But based on one opinion from another member of this discussion, he has better response, battery and stability with 4.2.2 than with 4.4.2

But yes, answering your question, you can easily root and make a CWM recovery.

But based on my observations here and on other forums, I haven't noticed any user that have brick their phone installing original firmwares made for their devices. Using SP Tools.
[Android General] ivanox1972:
I have rooted 4.4.2! Install vroot and then su from play store and work! Now I want to try this biscuit rom for better touch experience. As I see it is best and safest for common usage

I just afraid of losing imei. I have stock 4.4.2 ulefone now. Will I lose imeis when flash it normaly from recovery

Thanks
[Android General] estuardo4:
I cannot asure you that you won't lose your IMEIs. My advice is that you have to make a nandroid backup and then proceed to flash Team Biscuit's. If you lose your IMEIs just restore from your nandroid backup to return where you started. I've done this several times and when I return to my backed up ROM, my IMEIs are always there.
[Android General] aaallleeennn:
Hey mate, is there any other custom rom 4.4.2 or 4.4.3, or maybe 4.4.4 except the one from team biscuit?? I can only find 4.2.2 based roms
[Android General] estuardo4:
Aside of the ones I listed before (that are ROMs with different OSs made for Nibiru M1 and Mlais M81) I haven't found a custom ROM like the one made by Biscuits Team. I've searched and searched Chinese forums to no avail. As much as I'd love to test MIUI or ColorOs or TouchOS, I much rather prefer to have a custom ROM that allows more tweaking and more tune ups specifically made for our devices.

Thanks, friend.

As I see biscuit is best to try at start...

What I hate in stock (not many things) is too small icons, FONTs specialty, all...

My eyes are not the best...

Is dpi same in biscuit as stock?

Can I decrease it anyway??
[Android General] cdr400:
[MENTION=1882324]estuardo4[/MENTION]

I've Biscuit Team ROM and Lenovo Camera v4.1.13 as you. Initially it worked OK but now, when recording full HD video, it hangs on pressing stop button. I've tried reinstalling the app without success.

Any ideas ?

Thank you.

Best regards,

cdr
[Android General] estuardo4:
I'm almost 100% sure that dpi is greater than stock. If I remember correctly, dpi on stock was 280 dpi and with Team Biscuits is 320 dpi. I have it at 300 dpi and the font is big enough for me (My sight is not what it used to be).

You can change dpi either editing the build.prop file or using an app like, for example, Rom Toolbox lite.

Other ROMs like MIUI and One Touch uses 420+dpi (one of them even has a 500dpi resolution), that for our big screens are just ridiculous. For me, 300-320 dpi is just fine for our big screen. But if your young, you can even try 180 dpi.

I recorded three videos last Friday (all of more than 7 min long) and they recorded just fine. But yesterday I recorded a 10 min video and I lost it, because the lenovo apk hanged and I needed to force close it. I'll search for an alternative, as I cannot trust this app version.

[Android General] aaallleeennn:
[MENTION=1882324]estuardo4[/MENTION] hey mate can you please give links for other kitkat based roms? And what do you mean by saying they are other OS, does it mean I need to flash something else prior to installing rom? Or just flash them via CWM?
[Android General] estuardo4:
Not a problem, happy to help you.

To change language, go to settings and then go to the language and input menu. As they are in Chinese, to go to settings click on the gear icon and to go to the language and input scroll down until you see an icon with a "A" in it. Then, in it, click on the first option and inside you can change languages (I don't see a servian option).

And now, for what apks to remove, I can tell you that I've removed all the Chinese apks except for MTweak tools. A simple uninstall option is available for most of the apps, but for you to be able to remove /system/app apks, you'll need root and a root app manager like ROM Toolbox or Titanium Backup (you can use the one included on the ROM).

What other apps to remove? Well, as I don't like ROMs that includes pirated apks, I removed Titanium Backup and Root Explorer.

I hope this helps you. There are other /system/ apks that you can uninstall, but I wouldn't touch them if you don't know if you'll need them later.
[Android General] ivanox1972:
As I see some prog orange icon and white S in is some language manager? Can I use it or it is nothing (to rmove him)?
[Android General] estuardo4:
There are other zip ROMs that you'll be able to flash via CWM. I posted the link a few posts back. All of them are inside the threads of the Nibiru forums. There are several there, but they are not optimized for our devices, they are just made for other phone models and just ported for our phones. The developers are just happy for the ROMs to work on our devices, but no optimization or tweaks. For optimizations, I've only found Team Biscuit's

But if you want to try out MIUI, ColorOS, One Touch and others on your phone, you will find plenty there.

Just remember that, in order for you to be able to download them, you need to register and reply to the thread. All is written in Chinese, so you'll need to open two tabs on your browser. One for the original page and the other for the translation. Why both? Because using Google Translate, you cannot see the screenshots nor download the files, just clickong on the original page will do.

This touchbooster is touch recabli rate after install and I do not see any better. I like to decrease dpi and have bigger interhace. What is best way; if I have any ? What is native wallpaper resolution: 1920x1920? Can I add any font or just 1 can exist? Thanks
[Android General] estuardo4:
The touchscreen is of really bad quality, no doubt about it. We have to install everything available to make it seems better.

I don't know about the native wall paper resolution, sorry.

About the fonts, you can use iFont to have just one font on all interfaces, or you can instal Xposed Framework to install the Font module, that allows the phone to have different fonts on different apps. You have to have Dalvik runtime for Xposed Framework to work.

Do you happen to have the name of the Lenovo app with all the pro features turned on? the 4.1.13 version. The one I have installed is 4.1.13-perm-moved.apk but it only have a few options. I can't find the app on Google Play Store. Thank you.
