I am donating my Sharp Aquos Crystal to ONLY THE BEST DEVELOPERS. Its beat up and its been abused but there is potential in the phone for root, ROM and Mods. I will pick the developer and i'm basically hoping to send it to the best only! Please message me and let me know if you have any interest in doing substantial research on this phone and taking its code apart. I already tried and it needs a 3rd party program to access the boot-loader portion of the file system and ill tell you which one an provide a dropbox link to the loader you can download to get into it. I could easily take it apart and find a back-door but i work too often and cannot find the time to tear it down properly and look for vulnerabilities for free; Thus i am donating this phone as i will be replacing it with one i never dropped on the floor ;p cosmetically challenged yes, functionally operational YES. comes with a charger, box and receipt? YES. I want this phone to be developed into the most reliable and functional phone possible and if i have to do all the work myself... well i wont. or at least i wont share my findings if i have to spend time away from my family which is why i am DONATING this phone. I am a programmer for a very nice search engine we all use and i have already found 2 back-doors into the phone which i will also send over via PM. the problem is i cannot access the loader or storage from a PC using the standard drivers, only from within the phone. I need your help! You get a free beat up phone, and the opportunity to play with it. It will come loaded with Boost Unlimited to test the MMS, 4G, Calls etc. but i will only pay for 1 month. you MUST figure it out within 1 month! I can only spend 2 hours on my saturdays playing with it and i went back to my rooted G3 because it beats the Aquos in every category except for sleek design. however, i think this phone can be a powerhouse for entry level users and with its power i know it can be everyone's favorite device. I want ROMS. I want unattended root and i want this thing to be the leader in aftermarket mods. Can we make it happen? idk we will have to see. The CM team shot it down instantly and said SHARP will not release the loader in the US but i dont work for SHARP, so here in beautiful southern california i am safe playing with the software and you will be ok because no laws restrict us to OpenWare software like the rest of the messed up planet. I have permission from google to modify the software strictly for research so we are clear.

Message me and lets get this show on the road.

ill send it out via UPS and expect to see results in 1 month

Software-Reply 306SH Aquos-Sharp-Haxor

I already shipped the phone out to Palo Alto, CA. I have purchased another 306SH and I am waiting to hear back from the developer, a friend of mine from college. Hopefully by the end of the month we will have unattended root with a rom compatibility list. He has all the time we need to test and program the phone. I couldn't get past ROM upload without bricking the thing so maybe he will discover a better method. Like I said in my original post I only have a few hours a week to play with the code and its not enough time to test any configuration changes without losing my daily driver. (since my company blackberry doesnt make calls outside of company contacts list, I needed my personal phone still, but already replaced it.)

As far as the loader goes, i found a way in using ODIN4 but the newest update locked out the back door so once again i was stuck; my buddy is going to have to find another way into the folder. I will keep everyone posted on the results as i will be testing the first round next weekend. I'm currently playing in Kitchen with CM12 and testing the drivers in my box so worst case scenario i will find the right ROM config and stabilize it so we have at least 1 modifiable ROM to mess around with. I will release download links this coming weekend for the Alpha Release CM12 ROM and with any luck, we will have unattended root as well. I see great things coming soon for this device.

I am also working on a nice little camera mod that we will all use daily from an unreleased packet @ work and cooking it up for the Aquos so stay tuned! it should apk install on factory firmware which is what i will be testing after thursday evening.

Standby team Actual, We will have results soon Hooah!

[Sharp Aquos Crystal] jack_famous:
Successful root was achieved before i shipped it out using company software however i cannot release corporate software to the public since i have no way to remove it from the building (and i value my career.) but soon enough, i will provide source and links to the backdoor once we find the next one in the update. I just wish Sharp wasn't so dang grumpy about releasing their crap OS to developers. If they did, i'm sure most of the android community would be picking these 306's up off the shelves at an alarming rate. Oh well, sucks to be Sharp USA. When they want to collaborate to ID security risks, I will give them the exact same answer they gave me- "Nope i dont care who you are, you are not getting our OS pack or loader software."

hahaha we will see about that ;p

[ZenFone 2 Q&A, Help & Troubleshooting] Aanze:
Hi there,

I just bought a zenfone 2 in Japan and brought it back to France. Everything is working fine except for the 4g that is never "detected" by my phone even though the model I bought is supposedly 4g compatible. I only get the H+ symbol (whereas I had no issue getting it with the same sim on my previous phone)

Now I now that Orange in France uses frequencies 800 Mhz and 2600 Mhz for the 4g but I can't manage to find the information for the japanese version of my phone that was bought sim free (not through an operator like ntt docomo or else). And I don't know if it can be changed in a way or another.

Any idea how to debug this and eventually correct it if it is only possible ?

My zenfone is rooted as I figured it might maybe help to tweak something..

Thanks in advance

[ZenFone 2 Q&A, Help & Troubleshooting] Aanze:
Thank you for your reply.

However, on the link you provided it is specified that the 4g capabilities of my phone (ZE551ML) with a worldwide firmware (WW) which I flashed on my phone are as follows:

"FDD-LTE: (WW)

2100MHz(1)/1900MHz(2)/1800MHz(3)/1700MHz

AWS(4)/850MHz(5)/2600MHz(7)/900MHz(8)/800MHz(20)"

I'm not sure how to interpret it but as my carrier specifies the 4G frequencies for FDD are 800Mhz and 2600Mhz it should be fully compatible ?

As for the APN I set it just as specified on my carrier website.

My phone still seems limited to HSPA+.
[ZenFone 2 Q&A, Help & Troubleshooting] drabharathan:
Same issue

My phone was bought from India. I now live in the UK and I don't get 4G on channel 20, 800MHz. My phone it's not rooted. My software begin is WW. No 4G. The disclaimer seems to be a bit deceptive. :confused:
[ZenFone 2 Q&A, Help & Troubleshooting] kanagawaben:
You are out of luck I think. The Japanese model has LTE bands 1,2,3,4,5,6,8,9,18,19 & 28. Orange in France uses LTE bands 7 & 20. So you are stuck with 3G unfortunately.
[Galaxy Note 4 General] h8Aramex:
I thought I should share my findings regarding the downgrade process.

It's a long tutorial, but I listed every step for newbies too.

Biggest issue I had with it - is that the phone constantly downloaded the LL update, no matter what. So here is the solution:

I have used my phone with this setup for the past few days, and it did not download the LL update.

Now I can use my phone on trip, during work, and only lose a few %. Back with LL I lost all my battery even with a few hours of use.

The battery life is pure GODLY now.

Downgrading does NOT trip Knox!

Preparation...

- Download ODIN 3.09 and the latest KitKat firmware for your variant from Sammobile.com.

- Uncompress the firmware file.

- Do a full backup of your phone and your SD card files by copying over everything to your PC and by using

Super Backup

app. No promo, I just used this one and it works wonderful. (For Contacts, SMS, etc.)

Install phase ONE...

- Power off your phone.

- Enter Recovery Menu, by holding VOLUME_UP + HOME + POWER.

Once you see the Samsung logo, release Power, keep holding the other two.

An Android mascot will pop up.

- Navigate with volume keys, and power. (power is "ok", volumes are up and down.)

- Go into "Wipe Data", wipe.

- Press reboot, then turn off your device once it boots.

Install phase TWO...

- Remove your back cover, remove SD card (just in case), remove SIM card.

- Keep battery, of course (lol).

- Boot phone in DOWNLOAD mode by holding VOLUME_DOWN + HOME + POWER.

- Connect your phone to PC, launch ODIN, load the unpacked firmware with the "AP" button.

Do not touch other buttons and switches.

- Press "Start", wait until your phone reboots.

Install phase THREE...

- After your phone booted, DO NOT CONNECT TO WIFI or INSTALL YOUR SIM CARD.

- Turn off wifi, make sure it DOES NOT CONNECT and DID NOT CONNECT TO ANY WIFI NETWORK!!!

- Go into Settings -> About Phone -> Software Updates. Untick "check for updates".

- Turn off your phone.

- Add a DATA SIM CARD. That can connect to mobile networks.

- Boot phone.

- Once it is booted, you will see that the phone will check for updates.. (yeah, to hell with our settings)*

- Open the notification, and you can find an option "NEVER REMIND ME".

* If it does not check, you can do it manually BUT ONLY IF YOU HAVE A DATA SIM CARD INSTALLED!

Then you can see what update you have, and whether you want to download it. Some people reported there are patches for KitKat on some regions.

DONE. You just outsmarted the evil Samsung. Good job.

- If you have your sd card installed, everything in place, you can now connect to wifi.

- Install/recover stuff, set up things, etc. You are good to go.

Ps.: If you are a Samsung employee, please, don't screw us over by force shipping some sneaky OTA to our devices. We do like to have choice what / which version we run, etc. Forcing crap down our throats is not really a nice way to treat customers.
[Galaxy Note 4 General] h8Aramex:
... Reserved ...
[Galaxy Note 4 General] zkyevolved:
Very well explained. I will keep this in mind if Lollipop doesn't start to get any better in the next update... ARG SAMMY WHY DID YOU DO THIS!
[Galaxy Note 4 General] xdm9mm:
good write up. In addition, in your "Install phase THREE..." go to settings>applications manager> disable the "software update". - the one with green icon... this will stop the phone from upgrading to LP.. and you can skip the last part of your tutorial.....
[Galaxy Note 4 General] h8Aramex:
I tried this one, but the update still showed up.

The only way was for me, is to tap on that "never remind me again" thing.

Oh well, if you had luck this way, that's fine too (at least we have a workaround handy if the original tutorial does not work for someone.)

Ps.: I hope the 5.1. update will fix all the issues (especially battery wise).

Though... the S6 5.1 update was a let down.
[Galaxy Note 4 General] cash2387:
Perfect tutorial man for those beginners. But I thought you might want to add in one thing. When you originally flash KK there will be a small 100+MB update that needs to be done. As it was said in the XDA TV video its for a battery issue. Once that downloads and reboots to install, go right back into the Settings->About Phone->Software updates and uncheck auto updates.
[Galaxy Note 4 General] h8Aramex:
Well. I was really tired when I read your reply and I could not remember if I ever updated adter the flash. Turns out I did, and now I have L coming down once again. Oh my.

Did a Nova backup, Super Backup, and I will reflash on the weekend. And now I will have to charge my power bank, and prepare a mobile charging cable too. Oh good times...
[Galaxy Note 4 General] cash2387:
Sorry about that, I know the feeling, I did that a few weeks ago myself. Hoping there was a 5.1.1 update, But turns out I couldn't dismiss the update once it checked.
[Galaxy Note 4 General] Jovan1997:
Guys ;) 'coming stupid question'

If I want to downgrade ti kk do I nedd zo check or unchek re-partition? And what about Bootloader?

Thanks..My lolipop have too much lags and battery drop too fast...
[Galaxy Note 4 General] h8Aramex:
I just do a factory reset in L, then keep the stock options on ODIN. That worked for me.
[Galaxy Note 4 General] h8Aramex:
Ok, so since I had to reinstall the phone, I tried what you said.

Well, I only get the L update, after it checks for updates... No small update or anything.

I used this firmware: http://www.sammobile.com/firmwares/download/44754/N910CXXU1BOC3_N910COXX1BOC1_XEH/

N910CXXU1ANK5_N910COXX1ANK2_N910CXXU1ANK5_HOME.tar.md5

Maybe some regions do have small patches for battery issues (even on Kitkat)... or some regions don't have this "latest KK" as md5 file.
[Galaxy Note 4 General] cash2387:
Could be the difference in versions your right.I used this one to go back to 4.4.4. It's the AOA1 build for my carrier

[Galaxy Note 4 General] ucallmebobby:
I saw someone else post on another thread that you can't downgrade from BOF5.

This is on Sprint.

Is that true?
[Galaxy Note 4 General] h8Aramex:
Yes, I have read the Sprint forum (I was searching for something else on Google), and some people did complain about that.

It's the bootloader or something.

Well, I am pretty sure it's possible to downgrade... somehow.

(The S4 Mini got the same problem. Once you are on 4.4, you cannot downgrade, it will just fail at the end of the process.

For God knows what reason.)

Uhm... make a thread in the Sprint forum, and if someone got his Knox tripped, he can try the reformat and other options to flash the KitKat rom back. (Well, even if he succeeds, we won't know whether those checkboxes will trip knox or not. There is just no way to tell. Knox should _not_ be tripped when flashing official firmwares.)
[Galaxy Note 4 General] xxSTARBUCKSxx:
Please dont make another thread in the Sprint forum pertaining to downgrading to KK after being on OE1 bootloader and up.

Theres too many already and its been answered numerous times when OE1 first came out. I replied to your Question in the other thread about going to KK from LP and with you being on OF5, as of right now, its not possible and Odin will prevent you from bricking your phone, giving you an auth error.
[Galaxy Note 4 General] hackertom:
hi my friend, i am in 5.0.1 lollipop with DBT Firmware CSC N910FXXU1BOC3. It is save to downgrade without trip Knox counter? Can you tell me the kitkat version who download?
[Galaxy Note 4 General] DionWhite33:
I did this to my Note Edge too....LP is garbage and people praise it? I guess newer is not better...great tutorial though. Its people like you that take the time and do things like this that makes the world a little better place.
[Galaxy Note 4 General] amd-dude:
I'm only getting a NAND write start /fail error message. My phone has been doing some goofy stuff lately. Screen locks up (blank) and nothing responds. I get the menu lights for a sec and then they are gone. Plug the phone into the pc leave it for a few minutes and everything comes back. Dunno if that is a software or hardware issue.
[Galaxy Note 4 General] slit:
Hi again,

it's impossible to downgrade to 4.4.4 from 5.1.1 AFAIK (in N910C)

thanks sammy for your locked bootloaders...
[Galaxy Note 4 General] karkand:
so, it is success to flashing the 4.4?

could you please advise about it?

thanks
[Galaxy Note 4 General] amd-dude:
Was indeed a hardware issue, my proximity sensor was being a royal douche. I did not flash the kit kat rom though however the phone flashes fine through TWRP recovery, which is how I got back on lollipop.
[Galaxy Note 4 General] asia559571:
Nice Tutorial

Hi h8Aramex. Very well explained tutorial, I expected the downgrade to be far more complicated. I never upgraded to LP myself although I did on my S4, couldn't believe how **** LP was regarding battery consumption and I think the M upgrade maybe just as disastrous but waiting for the peoples experience. Anyway! I have copied your tut for future reference if M is a complete failure.

Question: was you on LP 5.1?

Many Thanks and Kind Regards:)
[Galaxy Note 4 General] hiimimtayaz:
Guys! Need help.... I have been trying to downgrade from 5.1.1 other 4.4.4 but unable to flash the kitkat firmware on my N910C.

Always ends up with NAND write FAILED.

I have heard that we can't downgrade from COJ5 bootloader since it is locked....

Please advise...

What if I choose re-partition in ODIN will that help me ???

Thanks in advance for your comments.
[Galaxy Note 4 General] gabrymr:
You can't downgrade from COJ5, end of the story.

I am new to the Note 4 and ran into the NAND part. I'm on the latest version of Lollipop and would like to downgrade to KitKat due to the terrible battery life.

Any advice? If I go about flashing KK via a custom rom, what would be the stock rom for KK and how would I do it (I read people's posts here on how there is a resized partition, which is why I must ask).
[Galaxy Note 4 General] Calen77:
Hello,

you can downgrade from any bootloader.

I have the same N910c with unlocked bootloader.

When i upgrade to 5.1 i flashed a rom who have a file to upgrade a bootloader to 5.1. When i upgrade to 5.1 for my surprise the file was from a locked bootloader then i never more cameback to 4.4.4.

Last week i download an original Unlocked Samsung firmware from uruguay and upgrade to Android 6. Just 2 days a go i flashed a 5.1 rom to see if my note 4 was unlocked again and YEAH !!!!

I come back to 5.1 and my note 4 is Unlocked again !!!

Just ine thing, i have to try more then 5 times to upgrade to Android 6, i believe because it was with an brasilian 5.1 firmware, but after 5 times it was fine.
