[Q] Rooting Galaxy Note II clone - Android Q&A, Help & Troubleshooting

Hey everyone,
I came into possession of this chinese Android smartphone built to mimic the Samsung Galaxy Note II (it looks like a pretty decent rendition actually) and I wanted to see what could be done with it.
The device claims to be running Android 4.1.1 but it's a blatant lie as evidenced by the total lack of the Holo Theme and other telltale signs, unfortunately every single app both on device and on the desktop seems to be fooled by this, the closest I got to it spilling the beans was a "API Level 10" which would place it around Android 2.3 if I'm not mistaken. In fact, the diagnostics screen claims this to be MocorDroid2.3.5.
The phone itself calls itself GT-T7100, and ADB names it mt_gt_t7100, under Software Version I see MT6577-TC611-EN-2PIN-V04, I assume MT6577 refers to that one motherboard that seems to be found in many of these devices, and plugging it on the computer reveals its USB device name to be "Spreadtrum Phone", the vendor id is 0x1782
Using all these clues I was able to identify him as this little guy here
www (dot) szrming (dot) com (slash) en (slash) Products (slash) T7100 (dot) html (can't post links)
Which seems to be a variant of the much more popular N/H7100 where the jokers were like "Let's reduce the onboard RAM to 256MB" so yeah, pretty painful. It takes like two apps to slow this thing down to a crawl.
I wanted to maybe upgraded it to a newer version of Android or at least root it so I can get rid of some stock apps that are always running and eating away the limited RAM, so I tried looking around but none of the "one-click" rooting methods seem to work, not even those designed to work for that version of Android.
I have found that one guide that claims to work for all phones using the SC6820 processor but I kinda stopped there because I need to flash it and I'm not sure I can correctly identify the ROM since I'm not even 100% sure it's the T7100 I found there.
I'm posting this in the hopes that somebody has the same model or knows enough about ROMs to tell me if there's some kind of "generic" one that could work with this particular phone considering the chipset it's using
Thanks in advance

I think I was taken :(

I bought a Nextway Fast 9 X from spemall.com as shown here:
http://www.spemall.com/Nextway-F9X-...PS-Screen-2G-Ram-1-5GHz-4K-Video-Black_g.html
After fully charging the tablet I started using it and it froze. I then restarted it and its froze a total of 5 times. Its had errors with the launcher, when opening the apps tab all the images would look like the background but pixelated.
Here is a link to the pictures i took: http://s1232.beta.photobucket.com/user/xstingstreetx/library/Defective
Next, I was able to disable some things for the tablet to run properly without crashing. However, this thing score terrible on benchmarks and is VERY slow moving. The processor is actually 1.08Ghz not 1.5.
I was able to root it thanks to Bin4ry see here: http://forum.xda-developers.com/showthread.php?t=1886460
Video by Bin4ry see here: http://www.youtube.com/watch?feature=player_embedded&v=7EpkrCq1gfM
I was able to overclock on the stock kernel and such to 1.152 stable.
I was hoping someone could help to develop ROMs, Kernels, etc to make this thing work better.
Any and all ideas or feedback is appreciated.
Things that I didnt notice when I bought it is: I dont believe there is bluetooth or GPS
Also the GPS and blutooth either does not exist or possibly the software in the tablet just doesn't work with it.

so you bought a non-brand cheap chinese tablet and now you want someone to develop a ROM for it ?
edit: wait. that is not that cheap. why on earth would you buy a non-brand tablet with a budget at 200$?

Well no other tablet has competitive specs that I found. However I didnt know this tablet wasn't a 1.5 Ghz quad core as listed on the sellers site.

if something sounds to good to be true. it probaly is..
sad to say the chances of someone making a ROM for non-brand products is pretty slim, since most ROM are created on the basis that a device is widely bought and used. Of non-brand phone and tablets there are such a variety that developing for them makes no sense.
Get your money back if you can, and get a branded device. For 200$ you can get a Nexus 7.
if you want the same size and format of the one you got, look around for what samsung, acer, asus, hell even what Point Of View have to offer..
Sorry, but you won't like it -
The main disadvantage of buying a no-brand device is although it may work better the known brands, in case of a fault (software or hardware), you're on your own.... Not many users have flashed/fixed/used this device. So if you brick it, get a bootloop or find a bug, not many can help you.
Not speaking about the variety of ROMs...
I've been there.... I've bought a no-brand phone and after a year it's main PCB failed. I couldn't find a replacement part and had to throw the device away.
Anyway.....
Use the device, enjoy and don't brick it

If the moderators will give me permission, I can give you a link to where there are 4 custom ROMs for this tablet. I have installed the BETA4 and it better utilizes the Retina Display (unless you have bad eyes, and there is one geared for that one as the defective one you are using does). I honestly don't know if your problem can be helped with software, but it might... I can also give you a link to the newest stock ROM and a Windows app to install it. I would rather get permission first to post 2 direct links... one is to Arctablet (and you can do a Google or DuckDuckGo search and find it by the way) and the other one is to a tablet distributor who was good enough to create download links and instructions on how to use the hokey Chinese installer. The question is though, is your problem hardware or a botched ROM?
It does not have Bluetooth or GPS. My Archos outdoes it in that way, but it is a true quad-core retina display and mine works very nicely... nicer now that I have the better use of the resolution available. Its wildly vivid. I honestly can find no real issues other than a few I had from not wiping the thing before I flashed it (oddly it suggested I not do so... which caused me grief w/Google Play eventually). It comes rooted, and if you have one of those that are like partly-rooted or whatever some call it, do a factory reset and it will come back fully rooted. The ROMs of course are all rooted. I have a cheap 10.2", which honestly if I had not had something else would have given me ulcers, but hey... I only paid $14 for it from Quibids (including bid prices), so I can't complain. This one cost me around $150 with a few extras, so a little grief I can handle. But so far... those are interesting words... so far, it is actually very impressive. My daughter has a boyfriend who is an Apple fanatic, and he's kind of fixated on it from certain similarities to what he is coveting these days.
I have it going at 1.2ghz (quad-core), although I have gotten it up to just under the 1.5ghz it claims (1440). It will do it, but I wouldn't bet on its stability. It comes at 1.0 preset from manufacturer, but is easily changed with the cpu app of your choice. I use Setcpu... works for me. It has 2gb ram... can't complain.
I read some arguments on the cameras, but I don't see it... I took some pics tonight of my daughter on her way to a costume party... they are the best thing I have this side of my Kodak. I'm sure it takes better video than the Kodak though. Anyway... its responsive, sharp, and does what I want. You have to buy a Bluetooth dongle for next to nothing to have Bluetooth though for some bizarre reason it shows its there. The one page that I mentioned gives advice along with pics on how to do some interesting mods to it. It is capable of more than they shipped it with. I am sorry that you are having troubles with yours... I don't know if you still have yours or not. I've only had this a few weeks. If you are interested, let me know... and if the moderators allow it, I will post links.
I hate that you have had such grief with yours. If I can help, I am willing.

Identifying some phones

A brother of mine recently bought two Chinese iPhone 5 clones and Galaxy Note II ones. And I wanna see what's in those, what features do they exactly have, what software do they run and what hardware exactly are they. I tried to google this and I stumbled upon these forums, though I never got a solution that worked for me.
Is there any computer software I can while having each of those phones connected to my PC that use which might help acquiring that information? You guys mention SuperOneClick, but that does nothing in my case - none of the buttons work, no drivers get installed. Oh, I don't know if it matters, but I'm running Windows XP.
Many thanks in advance.
In most cases those Chinese clones don't use any of the mainstream phone os like android, IOS, WP8. They use other os such as bada or meego and put skins on the os so that they look like the mainstream os. The reason for this is coz of too much competition and low price phones in the Chinese market causing the production of low standard phones and tabs and phablets that somehow leak into other established markets... In some special and kinda rare cases those phones do come with stock android. In this case,The reason drivers don't install is because the manufacturers haven't released the drivers probably because the phone isn't widely known. Probably start searching for the manufacturer and ask for the info and drivers. And maybe, just maybe, they will give you the info. If it has the Google playstore download an app called android file info. It will give you a the info be it hardware or software including your IP address

Thank you for the reply.
Though the thing is, e.g. one of those phone that I have pretty much looks this one:
"Airphone i5 Smart Phone MTK6515 Android 2.3 OS IOS Menu Original Size i5 Wifi" (google that, turns out I can't yet post external links within my posts)
and as you can see on that site, they pretty much claim that it's Android based. Mine has 4 GiB though, or so it seems - when I connect it to my PC, it detects a FAT32 disk of that size.
So, how do I find out what those really are? Is there anything I can use on the menu to maybe see the real technical spec? There are many of those iPhone 5 clones on the internet, all of which claim they are MTKxxxx hardware inside. Should I trust those website? And what is that MTKxxxx? How do I find out which version (if any) mine is? How do I find out what's the screen resolution, CPU speed, and the RAM it really has?
Thanks in advance.
Mtkxx devices can be trusted. They just make phones that look like iPhone but are really just android. Since it is android go to the Google playstore and download an app called android system info. It will give you all those details... Believe me it does and doesn't require root

But how do I install it? This phone is a bit weird, for instance, when I try to watch a video on yt through its Youtube icon it gives me an error "format no supported". How can I even know if it's a real MTK, it just looks like one of those from those websites :\.
On a computer Google 'Google playstore ask download' download the apk. Then copy it to your SD card. Put the card into the phone. Using the file manager in the phone, browse to the apk on the SD card and click it to install. Then run the playstore and you are done.
Another option is using whatever Internet browser that is on the phone and Google the same thing and download it through the phone (don't worry about data charges the apk is quite small) once downloaded run it by clicking it and install it. The start up the Google playstore as usual.

And so copied the file on the phone (using the usb cable), still to no avail. It won't load. The phone doesn't even have a file browser 'per se', though I managed to find somehow which might resemble it via the 'search' function. My guess then is, that's not an Android at all? How can I get the technical spec now? :\
I'm uploading two attachments. First is the error that it shows when trying to load up that file you told me to upload, and the second one is the folders structure on this memory card (the one that has 4 GiB). Is any of this telling us anything? Thanks.
Sorry pal... I don't think that is android at all. What android version was written on the packaging?

It doesn't say anything about Android at all. It claims it's a legit iPhone 5. Though obviously it ain't.
Is there anything else I can do to get to the spec?
Let me check on Google and see what I can find. But if it isn't android... It might be a bit hard to find out but I will try my best.

The only references to Android that I found were those on basically every single website that offers or mentions Chinese iPhone clones. There's nothing at all on the phone itself :/. As I said, it claims it's a legit iPhone 5.

Maybe its off topic but if i were you i would throw out this sh*t and then i would buy galaxy s1 for example...they are really cheap now...after that you could root it and then flash miui rom...(these roms are very similiar to ios).
Also if they could somehow hack internal memory amount to show 64gb they could hack other hardware info so it may show for example snapdragon 800 while its chinese no name
Still, that does not solve the problem at all. If I wanted to throw those away, that is just sell them, I'd still need to know what it is that I'm selling. You can't run a successful businesses on a market that you know nothing about and neither you can successfully sell a product if you don't even know its technical spec. This whole thing is giving me a headache already :\.

I've seen these before. This phone basically is a sciphone with a iphone 5 design. It runs on Java not android.
Android MTK phones would have just the stock android phone (I.E. W008+)
Goophone I5 has stock android ontop of a skin and only runs on android 4 (There is a update for 4.1)
This however is Java ontop of a skin because of the font, and it looks like the sciphone os. The settings are identical to a sciphone too.
Just to add to this, all mediatek phones (Chinese clones) come pre-rooted, MTK6515 is really slow, It wouldn't even run angry birds. Also when you turn on your phone does it turn on with a android logo (like the w008) if so then there should be a test mode by holding volume up and power or volume down and power when the logo shows up. But I doubt it's android and wouldn't have this feature. Also to test if it's android, when you turned on your phone for the first time did you go through setup? If so you should have had added a google account (They come with the play store preinstalled but runs at a older version) ?
Thank you for your reply. It makes things more clear yet.

The answer for all this is: no. I've never stumbled upon the Android logo when using those, none of those tests would run and they have never asked me for google acc, neither there's anything on their menus where I could put any google acc name to. I simply assumed they were Android based phones, as all the iPhone clones that I had seen on the Internet were said to run on Android.
If they are 'sciphones', as you said and they run on Java, how do I get the technical spec? What I need will be the chipset name, memory information (RAM), screen resolution, WiFi standards it supports, etc. If I'm ever to get rid of them, knowing that is a must. I simply don't wanna cheat anyone, just state clearly what it is that I have to sell.

Well, I was developing for the w008. I couldn't get round to a ROM with no kernel sources available and the device was abandoned to hardware today. I cant really say how to get the datasets really.. All I know is that it could also be a clone of a "sciphone" and have a different dataset to that.
Just a suggestion if it runs on java, it can run java apps meaning you could find a java app for system information. Not sure if there's one out but it would be worth a try. But then again I think it reads the settings of a file (like a bulid.prop) so then again it would give the same information as settings.
Don't know what to say really.

Hi,
This product description sounds familiar. The Chinese manufacturer's product description is usually very vague and ambigious, for example, a "tablet" (computer) can be described as a "pill" (computer) because the Chinese word is the same for tablet and pill (medicine-wise). So, here is how I would interprete the product description:
Airphone i5 Smart Phone MTK6515 Android 2.3 OS IOS Menu Original Size i5 Wifi"
Airphone i5 - Airphone, the brand and i5, the model
Smart Phone - usually means it comes with a large touch-screen (not a feature phone)
MTK6515 - the processor
Android 2.3 OS IOS Menu - it has some menus that looks like Android 2.3 and some menus that look like IOS
Original Size i5 - the phone hardware has the same form-factor as i5.
Wifi - comes with addditional Wifi connectivity (if without the word "Wifi" expect no Wifi)
I am sure if we were to scour the Chinese websites we will find many more such (seemingly deceiving) descriptions.

I9506 and N9005 is same same but different? (Compatibility issues)

Dear wizards!
As you know Samsung quietly released a "new" S4 (I9506) based on the same hardware as their current "flagship" Note 3.(SM-N9005).
That they are the same I got verified from Samsung in US (YES! They DOES sometimes answer) and on some other place as well.
It does make sense since that is a cost-cutter, the S4 sales are falling. Closing one whole production line seems like the logical way to go.
The "new" S4 is on pair with Note 3 in Antutu (actually a little faster) and I know that does say much but it gives a rough estimate
(they both are around a bit over 35k fresh but the latest Note 3 update slowed it down to 28k (plain vanilla except for Antutu and a hardware info).
It's shipped with 4.2.2 with Knox turned off and I must say that it feels like a "test-bench"-version.
It would not surprise me if the shipped rom was the that they where using on their ref.
So with that in mind I postulated that there should be a 1:1 interchangeability between those phones.
I share a few files for you, most important PIT-files in readable form and recovery images, all Philz.
(A working I9506, from N9005 (oldest and newest found) and a I9505 as a reference)
As you can see they are exactly partitioned the same with the exact addresses and all (except for the current loaded content).
Well, it made me very happy and confident (doh).
I started to test the simplest(?) or easiest and that was to see if a custom recovery would work. We have a "mended" Philz that is working
but I thought that the N9005 should work as well, but of course, it didn't.
Had some funny results (like the first "BSOD"! BLUE! and a "melting screen" that was really scary before I realized that it was corrupting the video mem).
So the question is Why? What am I doing wrong?
I don't recall where I got the "mended" from and I have no way of getting in touch with Philz and ask him so I turn to you for guidance?
Looking at them they seem to at least have the same structure (same preamble, not stripped etc) and are much closer then if I compare with the
one from I9505 that I included. I have not disassembled it and I don't know what good that would do, and the question is if all have to be compiled
from scratch but then the other question comes, why?
You who have read my posts know that I worked with this before and that I am ATM rusty in my "Carbon memory and 3-bit year counters
on old DECs (not THAT old but seen them!) and I HAVE trouble to find any documentation since all who have it (if there is) sit on it tightly.
So it's a lot of Googling and T&E here, but I feel like there is something fundamental missing here so I turn to you
Am I doing some basic stupid error here?
What I have understood the recovery.img like the usual "rescue" that bootstrap itself and bypass the rest just like you use to when you build
something with hardware, so you can read the parameters, dump mem etc or am I wrong here?
Does it go through the bootloader etc? If so, is there any correlation between the bl and the recovery? Unfortunately Philz have removed older
versions so I can't try them, and I don't know what he did to make it work but since it DOES work, there must be something that was not that
hard to fix but I have no idea why the same basic hardware doesn't play well with each other?
I know that 96% of my posts and PM's are about Knox and all the tish (I didn't ask to be thrown into that and the more I've found out the worse it is...).
Each phone have it's unique certificate so there must be some PROM they use to burn it in and it must be readable since the bootloader
compares the X.509 cert you have against its own when you get into the Knox-trap.
So could that be something that is different? I don't know how it bootstraps from the beginning since I lack mentioned docs and I tried with
Samsung but here they have not bulged here. Let's hope they do. They need to get transparent else this will kill them (There I go...Sorry.).
So have any of you gurus some idea what could the cause of this incompatibility?
If everything has to be built from source, ok, we will try to do that for the roms that have them as OS, but if this is something stupid that I am
missing it would be so great if we could just use that, since the only things that are obvious is the screen, mem, internal size and the useless pen.
Else is just the same even if I take those progs that just list EVERYTHING or go into the service menus with different *# commands and they are
like twins but not just right?
Any help would be appreciated since this is our serious try to get it harmonized, and I really really hope we can here?
Because If my assumption is wrong then we are indeed a sad bunch in the I9506 corner...
All the best,
Abs
Too many words, too many false assumptions
The reason for I9506/E330 is LTE-A. Currently, only Snapdragon 800 supports LTE-A. It's not a test bench for Note 3 and it haven't been developed with Note 3 compatibility in the mind.
Because Snapdragon 800 is highly integrated SoC (unlike SD600 or Exynos) they are very similar in architecture. Very similar but NOT the same.
There are still notable differences such as:
- 3GB RAM instead on 2GB. You may think, it's minor difference, but it doesn't. Snapdragon actually can access up to 2GB RAM. Adding 1GB more RAM is a bit tricky. According to kernel source it uses ARM PAE interface. I didn't explore it much, but should be like page addressing like on old x86 computers with DOS and >640kb RAM.
- different digitizers and S-Pen in Note 3. So, kernel driver for wrong digitizer may fail/panic.
- Different GPIO definitions. Even the same components may be connected to different pins of SoC (they are configurable).
- Qualcomm uses its own microOS called RPM for low-level access to CPU and GPU functions. It's closed source, signed by per-model key and thus not inter-changable. RPC commands between linux and RPM may have slightly different strictures/ids making linux kernel from I9005 not compatible with I9506 phone.
- modem firmwares of these 2 models use different commands to communicate making i9005 ROM fail too boot and go to infinite booting cycles. Modem (as RPM) firmware is signed by per-model key and not-interchangeable. I want to note: even fully compatible by hardware E330 and I9506 models cannot accept modems from each other (because per-model signature), but thanks to fully compatible interfaces to modem and RPM firmwares you can use boot.img and system.img from each other.
These difference should be already enough to say these 2 models are not 100% compatible. I've tried to use kernel from I9005 on my E330S. Even compiled from source and using I9506/E330S defconfig i couldn't make it work correctly. Thus, even in Samsung R&D these 2 models are developing completely separate.
Having up to date ROMs for i9506 why care about I9005 compatibility?
Thank you for taking time to answer! :good:
But then you have to postulate things so someone can prove you wrong! :victory:
There is an ongoing battle between two "big" microbiologists. About where a certain bacteria should be in the taxonomy.

I know I write too long and I was unclear. Sorry about that. Written too many "papers" where they loooove muchos pages.
And finished I see it's long again... kcuF, I'm incapable to write short. It really IS a occupational injury...
I don't look for the similarity with I9505. I know it's a Snapdragon 600, only mentioned it as a reference.
What I meant is the "new S4", I9506 and Note 3 (SM-N9005), both "international" and LTE that are Snapdragon 800.
I got information from Samsung that it was built on the same board. Can they still have totally different solutions in the end?
Because if it is the same board then I could avoid that Qualcomm proprietary tish you scare me with and try to look at the "Samsung level"?
In the I9506 shipped Rom there is a lot "S-pen things", but maybe that is in every one?
The download mode looks like this: I9506 and N9005.
Guess "Secure boot" is Knox but I don't know what "Write protection" stands for?
And I don't like "Write protection". For what? I use only protection for one thing! Blood! (Colorblind + Scalpel = Oops, hope he don't need that so much.)
Do you mean that they have not implemented a full 32-bit memory-bus? Not the usual 4 GB limit?
Just before CES, thay announced they are going for x64. I guess it's just easier to widen the bus then to have that banking and the
"640 kb is enough for everybody" and QEMM hell. Both where quite bad. Not to mention LBA... Or the 4 tb disks! (can't they learn?)
Is the microcode accessible as on Intel/Amd?
When I boot my x86 Linux machines the kernel reads the /etc/firmware that contains the latest version of the CPU microcode since it
doesn't "stick" but is updated - (Link to Arch wiki about it).
Is there some way to explore this further? To see what is similar and differ? JTAG?
I'll root my Note 3 if I have too. The shipped Rom is REALLY bad and buggy and I don't want to go to 4.3 since that leads to Knox-hell
and I don't want to be there either.
I hope that tech is right. I talked to a few, and he is one of the two that doesn't treat customers like cows but but where you can have a
meaningful dialog, held in a friendly and helpful way and not being a jerk. Seems unique at Samsung... Or am I just spoiled getting any at all?
What do you propose I shall go from here, мастер?
Thank you again,
Abs

Don't relay on Samsung words too much. There are many people working in many Samsung branches and most of them are far from R&D knowledge. These 2 devices built on the same SoC (SD800), not the same board. It cannot be the same board for very obvious reasons.
In the I9506 shipped Rom there is a lot "S-pen things", but maybe that is in every one?

All Samsung devices i have (I9100, I9300, E210K, E330S, I9506) - have many S-pen things inside. That's why you can find Note(1,2,3) mods for almost any Samsung device like ink effect on lockscreen. There is dead Note code inside all Samsung devices, because at some earlier stage code was taken from similar device and then started to develop for specific device by removing/disabling unneeded code and adding some device specific code.
Do you mean that they have not implemented a full 32-bit memory-bus? Not the usual 4 GB limit?

ARM appeared when RAM was enumerated in KB or MB. At that time, 640kb seamed to be enough for everyone forever
And with new trend of migrating to 64bit, i doubt there will be much effort to make 32bit ARM fully utilize 32bit RAM addressing mode.
Is the microcode accessible as on Intel/Amd?

It's not microcode, it's CPU code. Modern SoC like SD800 has many ARM cores inside besides 4 main cores. RPM is working on one of additional small cores. You may find rpm.mbn in official ROM update package. RPM is loaded at earlier stage by bootloader before linux kernel. It's signed and thus cannot be modified (and it's easy to hard-brick the device if you will manage to flash modified RPM).
but I don't know what "Write protection" stands for?

it's protection for bootloader, modem and all additional firmware parts loaded before kernel. Thus, you cannot flash modified versions of these parts.
Well, at least we have freedom to modify both Linux and Android parts.
Is there some way to explore this further? To see what is similar and differ? JTAG?

I don't have JTAG.
Qualcomm has Q-Fuses, so i don't expect possibility to boot Note 3 bootloader on I9506 after force-flashing it through JTAG.
Actually, i don't need JTAG to know that nothing useful will be done because N9005 is very different from I9506 from low-level point of view.
What do you propose I shall go from here, мастер?

It depends on you. You can get source code of i9506 kernel and compile your own kernel. Then get kernel source code from N9005 and try to compile working kernel for I9506 That will be very challenging work. While doing this you will understand the differences between these models. Probably, this knowledge will help to transform the code of existing (if any) N9005 CM/AOSP ROMs.

Possible to port an ARM Android rom to the Intel Atom version for the same device?

Hello all,
I just bought a Transformer Pad TF0310C (after a bunch of research it looks like it is the Best Buy exclusive version of the TF103C which unfortunately has an Intel Atom quad core, 1gb ram, 16gb storage), I am guessing there probably are no roms, or really anything at all for this device (spent an hour or so yesterday trying to find any and all I really found were posts of people trying to figure out what this device equivalent was to try and see if the roms will work for it)? I wish I had researched a bit more before I bought it, but too little too late (it was only $85~ so no huge deal). Assuming there are no roms for it, is it possible to adapt a current rom over to this architecture? It comes with KitKat on it already, so there is at least one stock rom that is out for this device, but is it possible to somehow take a rom from the sister device that has an ARM architecture, and port it over to be used on the Intel based tablet?
I am familiar with linux, several programming languages (not an expert in any, but definitely know enough of each to get any job done that I have needed thus far), manipulating devices to suit my needs, etc, so I feel that if I had enough documentation and resources available I could get something going, as long as someone with more experience tells me that it is indeed at least possible. There are probably going to be quite a few more people who are going to be looking for them as well as this device is currently a "best seller" on woot.com as a refurb, so I am hoping to try and help not only myself, but possibly the community as a whole by trying to provide at least a rom for the device, if nothing else, it will be a great learning experience for me.
Thanks all!

BLU Advance A4 Rooting and Custom ROMs

Hi friends, I've got a phone model for the cheapest I could possibly find that was New. Bought it on a whim for $30 on amazon (at the time) not giving too much thought to what value it had hardware-wise as I wasn't planning on using it as a daily driver, instead wanted to just see what the possibilities of it were as a little practice for android rooting and installing custom roms as I'm really not too experienced in the android field, but I wanted to learn.
Apparently I chose the wrong phone to learn on, since this thing has next to ZERO content on these forums or anywhere else on the internet in any capacity as far as reviews, custom development, forum threads, even customer questions.
The main drawback being that trying to look up anything for this phone will give you results for a different BLU model, the BLU Advance 4.0, since they have such similar names. Since I have this BLU Advance A4 here now, I have scoured the internet trying to find anything specifically for this model phone and found nothing, which is frankly surprising given that this was at one point the cheapest and still is one of the cheapest new android phones on amazon so you would think that people would use something like this to learn on without much care for bricking it.
So I'm here to make a thread for this model and for anybody else who has this model who is wondering the same as me. What, if anything, can I do with something like this? Why is there not more discussion about this model? I know there have to be enthusiasts trying to to a lot with little hardware, and a phone like this would be a prime example of a phone begging to have a lightweight rom thrown on it for learning and kicks. I will continue to try and do what I can with it while I wait for responses to this thread, please anybody who has any feedback besides "buy a different phone", give me something. I already to have a phone but I'd like to learn android hacking/customization on a different android phone before risking turning my main driver into a brick and I believe playing around with a cheap throwaway phone to see what it can do will be fun.
BLU Advance A4 (ADVA4)
Android 6.0
Chipset: Mediatek MT6570
CPU: Dual-core 1.3 GHz Cortex-A7
GPU: Mali-400 MP1
RAM: 512MB
Storage: 8GB+64GB mSD

Excellent plan! Luckily, I found your post before I bought 1 of these phones - so I thank you for this!
Worth noting, I came here hoping to buy this cheap phone as a dedicated music player (running, house audio driver, etc) but am also disappointed (but not really surprised) that there doesn't seem to be any prior effort at rooting or working on custom ROMs.
Edit: Have you tried this, or looking for google hits on hardreset.info, androidmtk.com, and cyanogenmod-roms.apk.cafe (I can't post directly links yet, sorry)? While not much, I did find a few other sites too listing firmware, if you already have the phone it's worth tinkering with it and see if you can get anyway. Good luck, and do report back if you do try!
ando en busqueda es la rom para este smartphone, podrias subirla??
