[Q] Samsung Galaxy Gio (S5660M, not S5660)

Hello,
I have bought a North American (Canadian, to be exact) Galaxy Gio (S5660M, with an additional "M" from the European model).
There are lots of tutorials about S5660 rooting and unlocking, but none for S5660M. There has been some reports that flashing S5660 firmware on S5660M to root and unlock made their phones unusable (randomly changing screen brightness, etc).
I tried searching on google and XDA, but could not find any relating to S5660M.
Is it too early to see any rooting/unlocking on S5660M?
Thank you very much!

Hello,
After some reading on here to compare unlock methods, I decided to take the leap into the unknown. I used the one published in this thread. (EDIT: Check out this one instead, perfectly safe.) (It turns out that the Gravity Smart, Galaxy Q, 551, 550, Mini, Ace, Fit, and Gio are siblings in a few respects. They all share Qualcomm 7x27 family SoCs.)
One deviation from the above linked thread is that SuperOneClick does not work on the 2.3.4 MUGK3 firmware. Updated versions of SuperOneClick do work with the firmware. Worst case scenario the program won't finish gracefully, but you'll have a root shell and you can work from there.
I've uploaded my modified superuser zip that'll work with the 5660M. Install through recovery mode. Removed - the superuser files within were long obsolete. Get the current ones through proper channels.
I wouldn't risk flashing the ROMs posted here until we can get a complete backup ROM, either from samfirmware.com (they don't have one yet) or through efforts here. I'll be starting another thread here for that purpose. Backup made a long time ago and SamMobile has had an official Odin image for some time as well.
There's been some issues reported with the 5660M, ranging from odd screen brightness behavior to bricking. (Many ROMs initially posted for the 5660, left "as is" also flash both the kernel and radio: not good.)
Goodbye,
Darkshado

Thank you for the reply! I have successfully rooted & unlocked using the modified zip. I am not sure if it was your's (I have done it prior to looking at your reply... ), but it worked!
thank you!

could you tell me how I could unlock my phone too.

New tonight
Just picked up a GIO here tonight.
BTW Future Shop in Canada has these on for $80 right now.
I think this is a great deal, for a very responsive 2.3 android phone.
OK,
So S5660m - is the version in canada it would seem.. I think there are going to be quite a lot of owners because of the pricing.
We should use this thread or another to setup a difinitive list of what works.
1. How to root the phone.
2. Unlocks that work - I have heard some methods brick Ms very easy. What is the best unlock method specific to the M
3. What ROMs can we use? do we need to have our own set of modified roms because of the modem portion?
4. Overclocking.. I have heard these can clock up to 1100 and run awsome!!
This is my wish list.

Hello James. Welcome to XDA.
Whoa there early thread starter! Use the search engine before even thinking of starting another thread. We don't have a dedicated Gio forum at the moment so things are scattered all over. Advanced search is handy as it outputs threads instead of posts.

Same as a lot of other phones, apply a zip file through CWM. You could also flash an already rooted ROM with Odin.

The bml5 method is safe. I noticed I had left a link to the older and unsafe stl5 method in my post above and removed it.
And keep your unlock code accessible somewhere on the phone. This phone is known to relock itself to Bell in some specific scenarios.
3. What ROMs can we use? do we need to have our own set of modified roms because of the modem portion

Yes, and no. If you only flash system.rfs, and maybe boot.img, it should work based on what others have reported.
I've cooked up a ROM for the 5660M that's called ArpegGioMod if you want to have a look.
Another point to consider if you want to run your phone in French: the Eurasian ROMs may or may not have that locale, and will likely have an AZERTY keyboard instead of a QWERTY one.
Do not flash radio (AMSS) or the other bootloaders from the Euro 5660. The former will make you lose all cellphone connection, the latter is unnecessary and increases your chances of bricking.
4. Overclocking.. I have heard these can clock up to 1100 and run awsome!!

Where'd you get that? The only kernel mods I've seen so far for any Gio are all ramdisk modifications that left the stock kernel untouched.

Just to clairify darkshadow, by "bml5 method" you mean this ?
0) brand new locked GT-S5660M phone frome the store
1A) root the device using this zip
http://forum.xda-developers.com/showpost.php?p=16962635&postcount=2
simplest method :
1.1 To begin, download the zip file from the link above and copy it to the root of your SD card.
1.2 Power the phone off.
1.3 Boot into recovery mode by holding the middle button and pressing the power button.
1.4 Once in recovery mode, select update from sdcard and choose the update.zip that you copied to your SD card.
1.5 Let the file flash and once done, reboot your phone.
OR
1B Follow EDIT2, for temp rooting on same URL below
2. Follow exact instructions as per here:
http://forum.xda-developers.com/showpost.php?p=17148825&postcount=334
(with the slight modification for HEX code to search specified here http://forum.xda-developers.com/showpost.php?p=17311381&postcount=358 )
Question: Does it matter if there is a SIM card in the phone when following these instructions ?
Any thoughts about "Network Lock Control Key" ?? ( ... would appear that this shows up as a separate issue for some users some time after unlocking see:
http://forum.xda-developers.com/showthread.php?t=992564 )
THANK YOU so much for confirming I got this right....I just want to make sure I am not missing anything, and these instructions are really safe as far as you know before attempting anything.

IMEI: Mod Edit: IMEI # Removed...not a great idea to post them on a public forum

Let me start with things you shouldn't do:
-Resurrect two year old, stale, threads.
-Post your IMEI for everyone to see.
Exactly *how* is your USB port messed up? Just not talking to the computer or not working at all?
Are you rooted? If not, get that sorted out by using one of the exploits that worked on Gingerbread. You'll have to do it manually, no SuperOneClick for you. (Although the binaries included might come in handy.)
It is possible to do the commands to get bml5 via a terminal emulator app, and then transfer that file over wi-fi. (Samba, WebDAV, FTP, Dropbox, etc...)
I'm not sure anymore if this is possible in GB, look into using ADB over wi-fi instead of USB. I've sold my Gio months ago, and all of my current devices run 4.1+.

[Q] Help me restore my Galaxy 3 to Stock/Factory

Hi there,
Long time lurker, first time poster and overall Newb.
I was wondering if anyone could please provide concise instructions on How to restore my phone to stock Galaxy 3 2.2 Firmware.
I have it Rooted (via super one click), OC3 Mod 2.6.32.9 and Kyorarom Infinity (v0.4.1 JPU) currently and am having major issues with stability.
Yet How can I restore it to Factory so that Kies recognises it?
Ive tried the hard reset with the button pressing but it just loops back to oc3 mod. Do i need to "unflash" it somehow or reflash it to a base package?
Please Help.
Regards

Take a look at the stock ROMs here & download suitable one for your region.
BTW, you should have posted in the Q&A subforum.

Yep cheers, ill give that a crack, and copy that on posting elsewhere. tyvm

Hi guys. The link provided above seems to be broken, well the links embedded in them are broken. Can anyone advise me, which stock firmware i need for a Samsung Galaxy 3 bought in New Zealand, and provide an active link?
Thanks a bunch

look over here

Is there a way to tell, which firmware i need as stock from the above link, by looking at my phone physically? Or checking somewhere in settings? Im guessing its region should be North America...

physically theres no chance given
just use the settings -> scroll down -> telephone info
you see the versions here

flashing any of these will allow you to connect to KIES, that will tell you if you need another version

KIES:
in my former days I had the thought that KIES is really necessary and tried a lot of eclair FW versions from the link above (samfirmware), but none of them established a succesful connection with KIES.
Therefore I upgraded manually with ODIN and uninstalled KIES.
I dont miss a thing until now.
Good luck in finding a fw which connects with KIES.
I read anywhere that XXJG1 or XXJG7 is one the rare fw which could establish a KIES connection. Maybe I am wrong...
A feedback from anyone which of the fw versions can connect to KIES would be very helpfulin this topic.
Cheers

[Completed] Can't Install Custom Rom

Guys,
I am using Galaxy mini GT-S770. I wanted to root my phone and to flash a custom rom. I was able to root my phone and. I can't Install Cwm. I tried both the methods By zip and odin. While going to cwm screen its shows E;/Mount error. also many features of cwm does not work. when i look for soloutions i found out that to use custom rom. so how can we install a custom rom without cwm. or how to fix the error. Thank you
- Mathew Joy

Hi,
I can't find any Samsung with model number s770. Are you sure about that model? If your device is a clone and not an actual Samsung device.... Using files made for a Samsung will likely destroy your device.
If it is a Galaxy mini, and you've made a mistake on the model number, here is where to ask for help,
http://forum.xda-developers.com/galaxy-mini/help
Again, don't ask there if it's a clone. You won't find help there, or any files of any kind that will work on your device.
Good luck!

ok, Thanks for the replay. To be specific I need a custom rom for my samsung (SM-G920R4) because I need to flush using Twrp 2.8.7.0 but I could not find a custom rom for my specific rom. What happened was my I just bought my phone from a dude who I met on sell and buy viber group here in Ethiopia (big mistake I know) and it worked fine for a day or so and then I logged my google account. After that my phone run out of battery so I plugged it and turn my phone on and when I did this I got frp locked it just bootloops showing me "custom binary blocked by frp lock". I took it to some phone fix guy and he managed to turn the frp lock off but it need to be flush he and also I tried to flush it using stock firmware with odin but that didn't work so I saw on xda thread that some guy was able to fix the same issue as me by using custom rom here is the link to that thread : http://forum.xda-developers.com/galaxy-s6/help/help-sw-rev-check-fail-device-3-binary-2-t3218678
But, I could not find a custom rom for my samsung model number SM-G920R4 us cellular, So I am begging this community of developers to save my phone if they have a custom rom for my model number? I am student and I can't offered to buy a new phone. Please help. Thanks for taking the time and reading this.

No problem. This should be perfect for a development member to pick up and assist.

bump. I mean, help? Same issue.

If the issue is you need a custom rom for that variant the op has then unfortunately you're out of luck, no one develops for that variant sadly.

Samsung Galaxy S6 Phone Boot Issue
Hi,
I'm new to XDA developers and pretty much a noob in Android related stuff, I have a Samsung Galaxy S6 with TWRP installed. Last week it went into a bootloop or something and wouldn't go past the "Samsung" screen. I wiped the caches but it didn't work, did a Factory reset but no good either, then used ODIN to install a Custom ROM in it but ODIN gave errors and that didn't work either. Basically, there was an error displayed in TWRP "No OS Installed. Are you sure you want to reboot?" I tried solving this following a Youtube tutorial. The guy flashed a Cyanogenmod in his phone using TWRP, I tried doing the same but TWRP gave an error " could not find meta-inf/com/google/android/update-binary in the ZIP file" . I extracted that file on my PC and it had only an md5 file in it"
Well I've been searching the internet a lot but haven't been able to find any S6 (920-F) Custom ROM which has a ZIP file that contains The META-INF folder (I'm not sure what it does) but I'll be really grateful if someone sends me a download link for it.
Or if there's some other solution for a problem then please help me out.
Thanks

Stuck on Bootlogo after flashing newest CF-Autoroot, whats next ?

I tried to root my SM-G930F with current firmware G930FXXU1DQB3_G930FDBT1DQA8_DBT with this CF Autoroot file: https://download.chainfire.eu/929/CF-Root/CF-Auto-Root/CF-Auto-Root-herolte-heroltexx-smg930f.zip The latest one is based on NRD90M.G930FXXU1DQD7 and I am not sure if this is a problem.
During flashing the phone rebooted once showing "Kernel is not seandroid enforcing", then after some seconds another reboot. I waited nearly one hour with the phone beeing stuck in the samsung logo. When I shutdown and boot up the same happens. When in Recovery mode it shows first some failed "update" but I can get in the menu, download mode also working.
Now I am pretty lost about what I can do next. Of course my data is prio1 so I was searching for a way how to recover the phone and keep my data. Prio 2 is I still want root.
I have searched the whole day and I found the following options:
1. Flashing the whole Stock Rom: As I have read this should fix the bootloop problem, but since it's a 5-part ROM it will most likely also wipe my data - I really absolutely want to avoid this if possible!
I also read in some cases you don't have to check "Re-partition" if you don't use another CSC (this would be the case). So I was wondering if I could flash stock without re-partition and erasing user data.
2. Flashing only boot.img and/or recovery.img: Chainfire writes "If it still doesn't do anything after 5 minutes, something has gone wrong, and you should probably reflash your stock boot.img and recovery.img." Funnily he doesn't provide any guide -.- I don't know if this is trivial (I have only some basic knowledge on the whole Android flashing) but I was searching like crazy for any tutorial how to do this. My idea was that in this way only the recovery and boot are restored and user data is untouched- correct? So the only guides I found going in this direction are those mentioned here: https://forum.xda-developers.com/showpost.php?p=67648452&postcount=2
Now as these are rather old I am even not sure if they still count for Android 7.0 as I don't want make even more damage. Therefore my question - is this a possibility to convert the IMG to TAR and flash them ? Are both needed or just one, is the order important etc.. ? Maybe someone has a more specific guide.
3. Flashing TRWP: I have not read much about this yet because I wanted to stick to the simple Autoroot method and also don't make things more complicated. But I was wondering if in this way the bootloop could also be fixed and my original goal of rooting also could be achieved?
4. Trying CF Autoroot with earlier version: I searched for any archive of the CF Autoroot images. Maybe I could get the phone back to work with an image based on my version. Problem is it seems Chainfire does not keep the older versions and I didn't find any in other places. Anyone got such version for the DQB3? It would be worth an easy try..
5..... any other possiblity ?
General question for the future: Does anyone know why the rooting went wrong? What was my mistake? I striclty followed the guide, have activated OEM and USB Debugging, started Odin as Admin etc. Is it a version mismatch issue ?
I am really thankful for any advise! In the past I flashed my SGS2 and SGS5 and never had any issues as I always followed the guides and was very careful. Can't understand why there is no warning for this particular case ..
Michael

Flash stock again using ODIN (do not change any settings) and use HOME_CSC instead of CSC and you will not lose any data
HOME_CSC = No Wipe
CSC = Wipe
Then follow the TWRP / SuperSU thread to get root

I flashed as you proposed and the phone is back to normal without any data lost
Thank You so much *detection*, You saved me a lot of trouble!
For anyone else having the same problem I used this guide (it's for the S7 edge but process is the same).
I will report back if I managed to root with TWRP and how to do it.
BR
Michael

:good:

I've got the same problem (stuck at logo after Auto-root). Do you know any working solution to root S7 Edge without loosing the data?
