Phone Review: ALPS F7100

bullriders · Jul 7, 2013

I purchased phone on ebay for $149.99. I was supposed to receive the Star N9000 (i9220) but ended up with the ALPS F7100

They both appear to be Galaxy Note look alike but have lower resolution. Physically appears to be built well other than not knowing if it has Gorilla Glass, which I assume it does not.

This phone does not appear to be have T-mobile 3G Bands unlike what is stated in the Star N9000 that multiple people in Amazon state 3g with T-mobile which is contrary to what the box says. The back of the phone for SIM1 says GSM/CDMA but I'm unable to verify actual operating band. Further search on eBay turned up a N7100 that is aesthetically similar.

I have a 3g SIM, but I assume that I am doing something wrong or I am using wrong T-mobile service. i.e. maybe compatible with Straight Talk

This phone can be ROOTED with SuperOneClick, just as I as able to do last night.

Software appears to be very basic Android 4.1.1 without modifications.

Pressing Vol(-) + POWER gets you into some kind of Factory Test Mode

Pressing Vol(+) + POWER Gets you into Android System Recovery so Flashing Rom appears to be possible.

You may need to translate.

Does anyone else who has this phone think its gingerbread, not jellybean

bullriders · Jul 10, 2013

I do not have it sorry

Sent from my VS950 4G using xda app-developers app

WEAREBORG2913 · Jul 16, 2013

It uses Either a poorly coded upgrade from gingerbread, or a Themed version of gingerbread....

Pretty sure its the latter....

And has anyone had any luck with root and/or cwm.
Does anyone have the rom for this phone....

And any help in installing stock android 4.1.x?

sexydj · Jul 17, 2013

yep

i own this phone the info says android 4.1.1 mt6575 1ghz dual core but atuntu & others showsAndroid version 4.1.1 Sdk ver/ 10 ( Android2.3.3) arm7 1998.84 Mhz
the phone comes rooted but with stock 3E recovery
i able ro flash CWM6X to it work ok you can flash only the Recovery from this package with mtk flash tool or nice recovery flashing tool i found here www-dot-labandroid-dot-com im new so cant post links
you need to rename the file Revovery to Recovery.img & follow the instructions

Im pretty sure real jellybean has higher kernel version.
also can you go through the steps you used to get cwm on this little beast
Go click on the android version number... I get the gingerbread icon...

I've actually got the feeling that the phone we are looking at is this one http://www.mediatek.com/_en/01_products/04_pro.php?sn=1056

making a custom rom

Can I modify a rom from another phone, to work on this phone?

AN3rd · Aug 2, 2013

I got the exact same phone... And i agree this is not 4.1.1 as it sas. More like the version of the SDK Android 2.3.3

Does anyone know if it possible to Extract the rom, upgrade it to 4.2 and flash it back?

Its not quite that easy, because of the partition layout, and because its not generic android.

It has manufacturers software, and needs some kernel tweaking.

Jellybean progress

Is there a way to make your own source, from a device... If I can I will attempt to make CyanogenMod for this phone, and maybe aosp.

Otherwise will risk phone using unknown sources... Is there any actual danger in this if its from another phone with same main board.

Also anyone know of a good way to find out everything that's inside this phone...

Or if anyone knows a good dev that might be able give us a hand... I have made a backup, and can send to him...

I have a couple of those phones.

Rooted and pushed CWM recovery and boot.img thru flash tool w/o problems.

But cannot boot into recovery no matter what.

Did anybody manage to use either CWM or TWRP on those phones?

The device is very unique with its partitioning, pretty sure you might want to modify cam to suit

Can you be little more specific?

Oh, OK, no worries

AN3rd · Aug 16, 2013

And BORG any progress? I rooted mine with SuperOneClick. That was easy... Haven't had time to try modding it yet...
It's clear the OS on this is not clean. I got some weird stuff. Cannot install on SD-card, i have to unmount to get apps on it.
Sometimes wifi -3g switches fail. And i loose connection. I hope JB can fix it...
B.t.w. I bought mine on chinabuye for around $100... greetz
