Hi
I have recently bought N9770 China Phone Which Has Dual Sim, Dual Core MT6577, Power VR SGX531 GPU, 8 MP Main, 0.3 MP Front, 512 MB ROM.
I've been looking at this topic: http://forum.xda-developers.com/showthread.php?t=1825332 and wanted to ask there but since I have less than 10 post so I can't reply there it seems. So I would like to ask here just for clarification before I proceed to root my phone: Would I be able to just root my phone safely without changing the firmware or ROM or any sort of drivers, as I think that any change to any of it will cause big problems. It has Kernel of Jul 25, and Baseband of Jun 14 (supposedly last updated by seller on Aug 2). The main reason for rooting is to change the DPI, trying to change the CPU governor settings to reduce clock speed when it sleeps to reduce heating, and for various other apps.
Screenshot: http://i48.tinypic.com/2reh64m.png
Also if possible, could you instruct me proper steps for it as to what applications would I need and how to do it safely? Previously I owned X10 Mini Pro on which I successfully did use nAa kernel by nobodyAtall (using FlashTool) + MiniCM7-2.2.1 by nobodyAtall, so I know the usual flashing stuff. But I am been very careful with this less known N9770 so any help would be greatly appreciated and helpful for others.
Thanks in advance

Hi there are no root tools at mo for MTK6577 processor. I am afraid the only way i know to do it is by flashing.its very easy as your only flashing the boot file nothing else it will do nothing except root and it can not really go wrong if you follow the instructions its done in 10 secs,i have used this method and its good and safe..if by any chance things do go wrong but they will not the original boot is in download to flash again
[Q] N9770 Rooting Safely Without ROM Flash
Ok, finally I took the risk of flashing using the guide which was posted by sas007 on his topic, which gave me root rights but eventually lost main and front camera access even on recovery mode. Tried using the orginal boot image which was linked there didn't help me either.
However, I did had whole ROM package for my model beforehand from which I extracted just the boot.img and scatter text file and flashed them instead, returning my phone back to original condition while remaining the root rights still there so this worked for me like a charm! Hopefully this might help for others as well.
I have attached the original boot.img and scatter text file for the model "e1809c_v77_gq1008_5647" and the ROM package filename was "N9770-20120725_e1809c_v77_gq1008_5647.zip" from which I extracted them.
Simply flash as per guide to get the root, then check your cameras if they are working or not. If they don't not then simply rename the boot.img and scatter file to something else so that you can extract and place the new files in there extracted from the attachment and perform the same flashing procedure with those new files and hopefully you will have your phone in original condion + root still existing in there.
Hope it helps
I did manage to root it. so my phone is working but did not have the camera issue.
had to install the drivers on another computer. now anyone know how to edit the desktops on the N9770.
and remove the google search bar on desktop I cant remove it or remove desktops.
[Q] N9770 Rooting Safely Without ROM Flash
Well, I did this on Windows 7 64 bit and I didn't had any driver issues, it installed pretty much perfectly in first attempt when I started flashing, on next attempt it started flashing.
The camera driver issue is related to the scatter text file that you're adding, the scatter file is like a configuration file.
Also, for anyone who got trouble accessing Google Play giving "No Connection" issue, it's because you have to set time and date first.
Thanks, worked perfect for me, using the original post to get root and yours to get back my cameras back

Reflash the original boot image only with sp flash tool, load firmware as normal ie select scatter file from original stock firmware and then untick everything except the boot image and flash.

Poor Hardware Decode Display
I have a question for those who using "e1809c_v77_gq1008_5647" firmware (I have this one) or any other firmware. Since the very beginning I have noticed very poor hardware decode quality which includes over brightness (which grays up black colors) and dull colors and not so fluid frame rate. Whatever resolution it is, it does not lag and syncs properly with audio but it just looks kinda stuterry 3gp-ish (well not that bad, but looks like playing LQ 240p video on YouTube). So far I am only playing videos using software decode with help of MX Player upto 720p and this does not show any such problems and the colors are vibrant and brightness tone is just perfect so that means the display driver is okay. However for unavoidable hardware decoding like YouTube I would like to know the solution for this even if it requires certain driver flashing.

You are totally correct a different driver combination selected while flashing firmware using MDT could help, also swapping uboots between the stock firmwares/firmwares also as long as same ie all ICS etc. I have done this so many time with other devices to achive what you said. However it is a risky daunting task to get perfect working combination of drivers and a lot of research Flashing.

Okay, I just tried all the combinations, and for each hardware part (Rear, Front, Display) there's just one driver that worked. The problem still not solved.
The drivers that worked for each are:
Rear: ov5647_raw
Front: hi704_yuv
Display: KD50M13_40NB_A1
I had following combinations for camera: ov5647_raw, ov7675_yuv, hi704_yuv
And following combinations for display: RX_50NT_365A, KD50M13_40NB_A1, truly3p2599, ili9481, RX_50NT_401B, RX_50RM_401A

Hi there everyone !!
I have read and tried to follow most of the posts about rooting the Star N9770.
My problem is I cannot find the firmware in my phone listed in any post ???
It is :-
1909C_V77_GQ1008_5647_20120920
Can I use any of the listed firmwares as I would like to root this phone for backups etc (use it for work)
Sorry if it's a dumb question but I really have searched for this file everywhere.
Don't suppose anyone has ported CM10.1 into the N9770 have they ??
I love Cyangenmod roms and 10.1 is awesome in my eyes feature packed just wondered

No its not dumb, the thing with these phones is that everything begins in china forums which takes a little time to travel to the english ones
That being said,
1. you cannot use any firmware without making sure it matches your smartphones hardware cause if you did it might lead to bricking or etc.
2. and the firmware in question wont matter till you have given sufficient hardware info ( mainly radio module, phone model, cpu { mt6577, 6575... } )

I've bought one of these Doogee DG100 smartphones, had it about a month now, and it's really excellent value for the price - I can't find anything I don't like about it. Well built, great phone and I'd highly recommend it. Well, Ok, the plastic fake leather cover's a bit naff, but hey.
I've rooted it using SRSRoot, flashed the latest firmware from the Doogee download site and I use MKTDroid for ADB access etc.
I removed all of the junk I didn't want, and removed the preloaded apps (twitter, whatsapp, skype etc) and reinstalled them from the Play Store - I didn't trust that some of them wouldn't update properly.
Managed to brick it too by doing dumb stuff, but the Doogee Flashtool just let me reflash the firmware and away it goes again.
Seems pretty bullet proof. Let me know if you get stuck and I'll try to help out.
Good luck!

Hi,
I don't know if it's because it's all written in Chinese when I get to the page with the actual zip on it or if it's because I'm blind and am missing some important visual cue on the page, but I can't figure out how to download the firmware or how to get the tools. Any advice on this? I even tried looking at the source code to see if there is a direct link to the file, but it's all full of JavaScript.
Incidentally, is there any indication on the site as to whether we might expect a newer version of Android on this phone in the future?

If you use the SP_Flash_Tool_v3.1320.0.174, you will manage to overcome that problem, but then you'll face the real one. The real problem is that your,phone like mine too, has a different version LCD display, that needs firmware 0926 to work right. If you use 0917, phone will flash, reboot, but show garbage on screen. I am asking Doogee to provide me the 0926 firmware (the one that my phone had installed when it arrived 5 days ago), but they don't reply to my mails. It also seems that the new display is not IPS as the earlier versions, as it greys while on angle and shows color shifting (obvious even with garbage on screen...).
I am waiting for a second DG100 within next week, so if anyone can share a way about extracting 0926 firmware from it, i would be obliged...

Download this files, extract them in folder with firmware 0917 and then flash them to the phone. This will work until we get the firmware from the factory (if it ever publishes it). Doogee no more for me, by the way, their customer support sucks...

Doogee announced new firmwares, 0926 and 1101 for DG100 at their site. Try 1101 first and then the 0926.
Solution
I solved the problem of the error 4032, steps:
1) i used windows xp, i don't know if it will work in windows 7.
2) i did use firmware 9_26 and flashtools v3.1328.
3) select the scatter of the firmware 9_26, leave marked only PRE-LOADER and click in DOWNLOAD.
4) Keep pushed (power) + (volume -) and connect the cable to the pc. You must see the red line, then purple and finally the green circle, then disconnect the cable.
5) Now unmark PRE-LOADER and mark the rest of the options and click in DOWNLOAD; then connect the cable keeping the buttons (power) + (volume -) pushed; now you must see the red line, then the yellow line and the green circle.
Thanks to Asterisd for your advice.

I use Chrome which seems to auto-translate and gives me a Chinglish version of the screens, which makes it a lot easier.
I assume you got to the pan.baidu download site? If so, in the middle of the screen there is an icon that looks a bit like a suitcase. Above and to the right there are two rectangular buttons, one blue and the other unfilled. Click the unfilled one. A popup window will appear with another two rectangular buttons at the top, one blue and one unfilled. Again click the unfilled one. That should start the download.
This site has a list of the latest downloads: http://www.doogee.cc/en/gb/xiazai.asp - I'm currently running DG100-0917 and about to try DG100-1101
Hope that helps.

What's the exact wording of the message(s) you get? I recall I had some difficulty with this and googled how to overcome it, including deleting incorrect application IDs and certificates from one of the Android files - sorry, I can't now remember exactly what steps I followed but if you can post the exact message I'll try to help.
I don't think I was able to get Facebook to update from Play, no matter what I did. I think I read somewhere that this might be to do with one of the themes that Doogee / Mediatek use being incompatible with later versions of Facebook.
Anyway, please post the message(s) and I'll see what I can do.
Cheers.

I would like to follow your advice but I can not update the device. Does not make me load a firmware of any kind. I would like some advice on how to make at least a firmware reload and restart it.
My question current is really about better understanding something in this whole Root and Linux learning adventure I think I am totally confused about.
Basically if no custom ROM exist or your device is not listed on the supported list of devices in any recovery program....
OR as in my case you want desperately to get the thing back running on it's true stock what do you do?
Your rooted, but stuck.
So my main question is:
What is the best way to bring a device back to stock if there is no stock ROMs available and factory reset will not work?
On any device in this situation. Mostly I am hoping to have it explained in a way I can really finalize this confusing hole in my logic.
Like can a recovery program find it if it is still on the device somewhere and if not, why not?
Thanks in advance.
Additional backstory if helpful.
I have a Wacom Cintiq Hybrid running Android 4.1 that is ( now ) rooted..
This is a very bad thing. The Real Stock ROM has palm rejection and all the drivers to make it work as a tool. So stock is the ideal but it is clearly not stock as my device supposedly came in the
box running 4.2 and with software and drivers to make it work properly with the pen. This has nothing. No software and the smallest amount of apps possible. Worse this is no custom ROM its on ( I think) as it would be the worst one ever and it was not rooted on arrival. I have no idea what happened before I got it. I may have made the mistake of rooting it really as I found out to my dismay there is no ROM support. So back to square one. I bought it ( very cheap for one of these ) "stuck and unable to go to the play store" and I did not realize until I got it, on a version of Android it was not meant for. Wacom is totally and woefully unhelpful in every way. They seem to want to quietly put this device behind them at the expense literally of their customers.
I have discussed this problem in another thread if more details on all this specific to this device are of interest.

My question current is really about better understanding something in this whole Root and Linux learning adventure I think I am totally confused about.
Basically if no custom ROM exist or your device is not listed on the supported list of devices in any recovery program....
OR as in my case you want desperately to get the thing back running on it's true stock what do you do?
Your rooted, but stuck.
So my main question is:
What is the best way to bring a device back to stock if there is no stock ROMs available and factory reset will not work?
On any device in this situation. Mostly I am hoping to have it explained in a way I can really finalize this confusing hole in my logic.
Like can a recovery program find it if it is still on the device somewhere and if not, why not?
Thanks in advance.
Additional backstory if helpful.

Hello & welcome to xda-assist,
If you rooted the device you changed the system /kernel in the process, if root is all you done you should be able to unroot by using the unroot option in your root management application, if you did further changes like deleting system apps and so on it gets more complex, the best and easiest way to get back to the original state would be a copy of the latest firmware.. If it doesn't exist you're somewhat out of luck, please refer to this link for further help & information..

Thanks for the reply. So no way to get the extract the original firmware? I don't wish to un-root. The device was set to a very sad state of affairs when I got it, unrooted, with something very unlike the stock firmware and factory date reset not helping at all. Persistently locked into a lower version of Android than it was not meant for and not running the drivers or software it would seem I need to make it function properly that came with the device.
Basically it lead to my curiosity of how one goes about extracting or mining the data that is stored somewhere on the device if all I did was root. Which is all I did.
It should still be there. Basically how do I get to it?
The link takes me back to the forums for help, however I found no help there after much searching before I asked here but thanks

The intended of xda-assist is to direct you to the most suitable board of xda, we do not solve issues for you or do technical support, please be patient, it often takes time for exotic devices / questions to be seen by someone who can give hints and answers..
Edit: but it's not that the original firmware is stored somewhere on the device by default where you can grab it and reinstall it..

Totally cool. It's a tough question.
The OG firmware thing is the toughest part to understand. Just wanted to make sure I was clear in my explanation and question.
I was trying to root my phone but i failed, doing so many wrong steps,now my samsung a7 is bricked, i cant charge it and i cant power it on, i also tried connecting it to a pc but the pc cant recognize it, any advice please to fix this? I really dont know what should i do now, thank you so much guys.
Can you talk us through the steps you did.
Is usb debugging enabled?
You may be able to use the samsung flashing software to recover but if you missed 1 or maybe 2 steps and have now wiped the device fully then you need to RMA. No os then no proof of your actions for a warranty claim to be rejected
enter download mode and flash firmware from Odin3

Im really sorry but i was actually not hard bricked, i thought i was hard bricked and i eventually got it turned on, so here is the whole story, i was about to root my phone and i watched a tutorial on how to but for some reason i trusted myself and didnt watch the video so i got into this situation, i enable USB debugging and OEM unlock( it deletes all of my files like a factory reset) i didnt know that i have to paste the magisk and the magisk apk to my phone and i flashed the bootloader thing from the tutorial i watched and then after that i decided to watch the tutorial and to my surprise the tutorial paste the magisk, so i panicked, i dont know what to do and i thought i was stucked at the downloading process so i decided to search more while panicking and i found that tenoshare Reiboot and Ult has this feature that will exit you to the downloading and now i tried them both but it failed, and i panicked more because now my phone just wont stop bootlooping so i just decided to drain its battery because its built in, i also tried flashing twrp but it cause me more panicking because it kind of glitches more so good thing i tried to go to downloading again by connecting to a pc and it worked, and the good thing is that the file i downloaded has a recovery flashable thing so i flashed it again, i escaped the teamwin bootloop and now i tried researching more causing me to figure it and i think i need to download the firmware again, but here is my biggest problem, i dont know the original place of the phone(i only know the country because its like a phone given only to me) i also dont know what is the original patch security of my phone( idk if its safe to just download the latest of the firmware) thank you for any advice

All you need is the correct firmware for your specific model number for your specific region/carrier and the firmware must have a binary that is equal to or higher than the binary of your currently installed firmware. The binary is indicated by the 5th character from the right in the firmware build number. Find that character in the build number of your currently installed firmware and compare it to the same character in the build number of the firmware that you want to flash. If the binary of the firmware that you want to flash is equal to or higher than the binary of your currently installed firmware then you can safely flash it, if the binary is lower than the binary of your currently installed firmware, you will not be able to flash the firmware that has a lower binary.

Hi, i just wanna know if i want to root my phone, is it important to unlock bootloader? And if yes, how should i do it in a samsung a7? Thanks!
Hi, i was planning to root my samsung a7 but i have a question that i dont know the answer, if OEM Unlock is enabled, USB debugging is also already enabled, why my OEM unlocked says bootloader is already unlocked even thought its still blue and not gray? Do i need to void my warranty and make OEM unlock colored gray or is blue enough? Thanks for all advice
