If your device doesn't have fastboot mode there is no point in trying to do anything with it. Anyways try downloading Poot and rooting with that. It's just an app that you install on your phone. I've tried it on my phones, it never worked, but a lot of people on the internet are saying it worked for them so you should try it.
[General Questions and Answers] jasperjax:
yeah poot has never worked for me on any device so far. always get (Ministro can not satisfy your application depedencies) error. just as this time around. but as i have located an "updated" rom for this device (and as i forgot to turn off device last night it took on the update on its own anyway Yay me) i may just try doing some light flashing. with odin at the ready just to be safe.

Anyone figure this out? I have a cricket samsung galaxy amp 2 (SM-J120AZ). I've tried every way possible to root it with no luck. I've tried all the methods above and none of them work for the amp 2.
[General Questions and Answers] jasperjax:
[MENTION=7703332]imagetrekker[/MENTION] Not yet. another device very close to this one is the SM-J120A (Samsung Galaxy Express 3) everything matchs up besides the android version is comes with.(6.0) would think if they root that one this one would be able to be rooted same way or if this one gets rooted first should work on other.

Where did you find that SM-J120AZ ROM ?

Hey man, this is very very important. You said you located an updated ROM for the Samsung Galaxy Amp 2 (SM-J120AZ Cricket). I've been searching high and low, so if you could direct me to where you found it, I would so very much appreciate it.
[General Questions and Answers] Greywire:
Can't format SD card for internal use

So I guess Samsung have saw fit to disable the ability to format an SD card for internal storage, which means you can't move any apps to the SD card. With the limited memory on this Galaxy Amp2 this makes it near useless!

We need to get root on this so maybe we can fix this...

adb shell sm set-force-adoptable true

Should fix it, but only with root...
[General Questions and Answers] jasperjax:
sorry had some computer issues shortly after a thunderstorm but im back up and running so Sorry for the very late replys

[MENTION=7990102]MuzicSoulWorldly[/MENTION] was actualy able to get it from http://updato.com/firmware-archive-select-model?r=&v=&q=j120az&exact=1

[MENTION=7991693]Greywire[/MENTION] Not quite you can do it with out root. commands are as this

adb shell
sm list-disks
sm partition <DISK> private
reboot

<DISK> needs to be replaced with the output of the previous command. For example sm partition disk:179,64 private. That will format the entire SD card and adopt it. Another way would be to use sm partition <DISK> mixed <VALUE> replace <DISK> same as with other way but value would be in a % of disk you want adopted example "sm partition disk:179,64 mixed 50" would make adopt half your sd card.
[General Questions and Answers] Greywire:

I actually discovered this right after I posted. :) Hopefully anybody else having this issue will see your posting though for the solution.

Still would be nice to get root on this phone. Any ideas on how to carrier unlock it?

[General Questions and Answers] Aimless Rambler:
I've seemed to latch on to the least popular devices of late. No love for the humble Amp 2 nor ZTE Zmax Pro in which I perchance to root. I blame on the wife and her nazi budgeting ways. Alas, I am here. Maybe I'll root this little bugger via old school Linux terminal and pure stubborness, maybe not. She's a lurker. Ha!

Update: After some research (not much, mind you I just got this phone today) I've noticed the specs are pretty much identical to the budgety Samsung J1. I'm going to try methods as prescribed for it using Odin and follow up here as it goes. Wish me luck (the wife fell asleep)!

successful root of sm-j120a

You have to flash this file (ENG_BOOT_J120A_PC1. tar) i used Heimdall. then use Kingroot to root the phone, i used the phone installed app from the webpage.

Good luck im fairly certain it will work for you guys phone as well since its the engineering bootloader for sm-j120az

Can anyone confirm Cody2885's method? I spent several hours last night trying to get it to work, but I'm having issues both with Heimdall (initialising protocol hangs when trying to get the PIT file from my SM-J120AZ handset) and with getting sgs2toext4 to convert the firmware available online to ext4 format (says "32 B/s" on loop when system.img is dropped in, can't read the img file?). Thanks in advance.
[General Questions and Answers] Aimless Rambler:
Not as yet. I'm preparing first, downloading everything including our stock rom in case of a softbrick. There's a good thread on our sister phone (Express 3) you may find useful. I'm going to try this shortly, I'll be using Odin not Heimdall.

Update: I can confirm it works using Odin. I'm not sure how to troubleshoot Heimdall (havent used it for awhile). I also followed steps outlined for the SM-120AZ's sister device the Samsung Galaxy Express 3 here >>> https://xdaforums.com/android/devel...-express-3-t3573646/post71644244#post71644244. If you read the aforementioned thread and decide that you do not want to have all the Kingroot garbage on your device and decide to buy the Super-Sume app I highly recommend reading the developers instructions here >>> https://play.google.com/store/apps/details?id=darkslide.com.supersumepro. As it stands, I'm still waiting for the results pertaining to the Super-Sume app. It's replaced Kingroot with SuperSU but is still processing the Kingroot uninstall (30 minutes into). If you just want root now at any cost try it but I'd wait for more testing information, might have to disable Knox, etc , Wifi issues staying connected with logon. All that kind of jazz. I'll keep everyone updated as I can. I have a job dangit.

Update: Rooted and no more Kingroot madness. Now, to figure out this Knox thing.
[General Questions and Answers] cmandrews3:
That's great news, many thanks for the update! I'll see if I can carve out time tonight or this weekend to try the method you describe.
[General Questions and Answers] Aimless Rambler:
It's a fairly painless process. Read the Express 3 thread I linked above and follow the instructions, be sure to thank the OP there! If you have any issues let me know. I had a few problems after the initial root but fenagled my way through it. Good luck!
[General Questions and Answers] Dratini:
Thanks to everyone here! I rooted it but I can't get rid of KingRoot the free way. I don't want to pay $3.99 to get of something that works already so I'm going to keep KingRoot, I installed the hosts blocker so maybe it will be unable to ping anyway. This isn't my primary phone anyway (although its specs are slightly better than the iphone 5 I've been using for years).

I tried to install the J2 TWRP recovery and it soft bricked it, I tripped Knox and I flashed the stock recovery. The TWRP recovery backup didn't work for me, the 'real' backup is about 9mb, I had to download a nearly 1GB file and extra 2 huge files, 1 was 900MB and the other was 2GB before I got to the tiny recovery backup, I'll upload it once I get back on my windows computer. Because of this...

I have attached an MD5 you can flash to recovery in case you break it, use it on the AP section, but unzip it first.

I don't regret getting this over the Amp Prime at all, its a great little device, Android runs surprisingly well on less than 1GB of ram. Apps still close pretty often sadly, but its bearable. The screen is a nice AMOLED display but the resolution is noticeably terrible like its a budget device from 2011 still. The audio is very clear, with viper4android its great! Don't think the flashlight works though. Anything else not working?

I want to get xposed on here (reason I tried to flash TWRP). Finally a budget phone that has root, and seemingly very recently too! I had bad luck with other budget devices (ZTE Zmax Pro, LG Tribute HD) and now I have a phone I can root!
[General Questions and Answers] Aimless Rambler:
I too came from the Chinese phablet (ZTE Zmax Pro). Sold it due to it wearing holes out in my pocket. My primary device is an old Nexus 5, I got the Amp 2 free for rolling my service over to Cricket. I went the paid app route to save my marriage. It's worth the 4 bucks, Kingroot was annoying. Not so much as my wife but easier to get rid of. :eek: Thanks for the MD5!
[General Questions and Answers] Dratini:
I been playing around with it a lot. It's very capable after I disabled Google play services services and some Samsung crap. Three OLED is awesome at night. I really want Xposed and a custom recovery on here, it would make it perfect.

Android runs way better on less than a gig than I remember!

I love free phones. They got so much better
[General Questions and Answers] HampTheToker:
Were you on the latest OTA when you acquired root? My dad's Amp 2 got it a couple days ago. Hopefully, this method is still viable. His is on the January 2017 security patch.
[General Questions and Answers] Aimless Rambler:
Me personally, no. I disabled automatic automatic updates as soon as I got the phone. I imagine that this method would still work though. I'm currently looking at a TWRP option for recovery. I'll update as soon as that milestone comes.
[General Questions and Answers] jasperjax:
Very nice I knew the answer was there some where just couldn't put 2+2 together. Now if can do custom recovery (unlocked bootloader) that would make this device a very very good budget phone. Root alone makes it 10x better (once debloated that is) lol.
[General Questions and Answers] HampTheToker:
When I click on the blue button in SuperSU me prep it just says valid copy and doesn't do anything. What am I doing wrong here?

Edit: Nevermind. Apparently, I lost root after a reboot and had to reroot.
[General Questions and Answers] Aimless Rambler:
Click on the blue button and wait. It should say something along the lines of kingroot located, then progress into the uninstall phase. If nothing appears to be happening after a few tries, reboot the phone and try again. If you still have no joy (as they say) you might try uninstalling the super sume app and then reinstalling it. That's what I had to do. SuperSU should be installed, you might want to check.

[General Questions and Answers] jasperjax:
Yeah that stock that I posted was from the first ota update so it's as stock as your going to get unless some can get a backup of the true non-updated stock. Don't think it really matters to much but with out anything to compare to its really hard to tell

*Edit*

And yes it is the full rom not just the update package.
[General Questions and Answers] HampTheToker:
You, sir, are a gentleman and a scholar for posting that. Haven't needed it yet, but I do anticipate it until there's a working TWRP img to save us from ourselves.
[General Questions and Answers] Dratini:
I wasn't either, but I think you should be fine, its not an exploit, its a file that allows you to get root.

I tried to update and now I can't since it knows its been rooted. As long as you don't care about tripping knox, the recovery I uploaded will save you if you have a problem.

Mine is a stock recovery. I only got it because I wrecked the boot with a TWRP that didn't work for it. The actual rom is huge. its like 900MB, the first file that I downloaded. If you want that one its huge: https://docs.google.com/uc?id=0BwvezwPRpyjkOXI1NnYxZjRiVE0

I googled the exynos chipset and chose a phone that had the same processor. I forgot which one it was. I thought that was all that was needed.

Labeled twrp-3.1.0-0-j2lte.img (Galaxy J2) I don't know why I chose this one but I have OSX and I don't know how to use heimdall, so I would rather try a lot of recoveries if I can use a 'close enough one" at once.

Since I already tripped knox I don't mind flashing more random ones if you have any ideas. How were you planning to get TWRP working?

Yeah I mentioned this as well.
[General Questions and Answers] Aimless Rambler:
Didn't know it until I tried, but no doesn't work for me either.

I've been loitering in the Galaxy Express 3 and J120F threads in my spare time looking for a similar route. We may have to commit to compiling our own.
[General Questions and Answers] HampTheToker:
Sorry. I originally read through this thread a while ago, so I've clearly forgotten a few things.
[General Questions and Answers] Dratini:
That sucks, I read through the howto but I don't understand it at all. It probably isn't hard. What are the requirements for a TWRP to work? Would CWM be easier? I prefer TWRP but if I can get clockwork I can add xposed that way and it is all the same to me. Really wanna get that on here and be able to backup the rom.

no worries man, just confirming its a problem of root. I haven't seen any other issues though.

As a secondary device I use for nigh reading. Highly suggest you guys get CF.lumen, Lux, greenify, and if you disable the google play store and google play services and use aptoide instead you can get more than 10hr of SoT. With Viper4Android the audio sounds amazing (maybe it would be good without it too, there is no artifact that I heard with my KZ ATR and other KZ headphones). Liveboot is fun for booting up, but since I use quickboot, its rarely used although its fun to see the nerdy bootup. Really want to get xposed so I can get microg for apps that require google play services.

I messed up the DPI on it, easy DPI changer has been the best one for changing DPI for me. I used another one that broke the DPI, and I ended up using some commands to set the DPI on adb.http://www.androidbeat.com/2015/07/how-to-change-dpi-of-android-device-without-root/ In case anyone has a problem with it... I set it back to 240 so it would boot correctly.

Tomorrow I will try this one: https://xdaforums.com/android/development/recovery-official-twrp-on5ltetmo-galaxy-t3422730

It seems to be similar at least in terms of processor and the version of android. J2 failed but I don't know what the requirements are for working TWRP.

I've asked some people on IRC and they told me it has to be compiled for this. This is a guide https://xdaforums.com/showthread.php?t=1943625

It probably be easier to change a few settings from something that is similar to this build such as the the on5 or j2.
[General Questions and Answers] Aimless Rambler:
I'm subscribed to that TWRP discussion also. The Samsung is a secondary device for me as well but I might as well try right? Thanks for the suggestions above!
[General Questions and Answers] Aimless Rambler:
Thanks again! Just had to use it due to trying a recovery. No joy.
[General Questions and Answers] Dratini:
Looks like we will have to wait for a recovery or make our own. I'm a little surprised that its not more popular, its a free phone and I'd assume that people would want to root it and do stuff to it. Its not as popular as the ON5 even though I think its a little better with the AMOLED.

I don't know how to do it so I will probably wait around until someone makes it or in my spare time I'll see how difficult it is to make. The battery life after disabling google play services and the telephone stuff is unreal. I legit love this phone, and I now feel super ripped off for buying apple products. I just spent $830 for an iPhone 6S, an SE and an Apple Watch together and they don't give me good battery life, an AMOLED, or the amount of customization that I got on this phone. I waited months for a jailbreak and its still not close to what I can do on this phone. I can't wait to get a better budget android phone that I can probably do way more on. Shame android is crippled by google play services draining the battery, its great without google.

If I get recovery working or xposed I'll definitely post. Its the only thing to make it perfect.
[General Questions and Answers] Aimless Rambler:
I've been an Android fan since my Samsung Captivate days. That's a milenial ago in tech years. If you want to have fun with a budget device I'd suggest buying a second hand Nexus 5. As far as a recovery goes I'm in the same spot.

I would HIGHLY suggest a OnePlus 3T. As I said before, the Amp 2 is my dad's. I have the 3T and I love the hell out of it. Best phone I've ever had hands down. It's even the top device here at XDA. Extremely root friendly. OnePlus even honors their warranty regardless of root unlike other OEMs. This community put them on the map and they haven't forgotten it.

My first was the Samsung Moment. Android 1.5 Donut on a Samsung phone with a slide out keyboard. Now, that phone had some cool factor. I'd totally buy another one if Samsung remade it. Early root junkie back then were rockin' the HTC Hero, though. Still loved my Moment.

That's exactly the best place to get TWRP going on this phone. I've only ever built TWRP once before, but it was for a crappy RCA tablet and it didn't work out, anyway. I have two 7 year old boys, so I couldn't make time for it if my life depended on it. I'll help where and when I can, though.
[General Questions and Answers] Dratini:
Man thats such a long time ago. My 3rd phone was a Droid, loved that thing. Its around the same time as the captivate.

I've heard they were bad at first with warranty. Picked up a friend of mine's phone via truck when it was invite only. Said they never got it even though they did the pickup. Hopefully they got better since then.

Man the Samsung Moment.. I made so much fun of Samsung for their ridiculous names. Nouns, Adjectives, Verbs, all random and now its Galaxy then a random noun.

Hi Everybody, I've tried flashing back to a stock rom because I soft bricked my phone with the link you provided. Everytime I try to flash the phone in Odin I get a fail. idk if I'm doing something wrong or whatever but I tried asking in my own thread but no replies. I can't even download any apps nor does the internal storage work or SD card. I want to flash my phone back to stock. Can somebody tell me what I'm doing wrong or is this rom incompatable or something thanks......
[General Questions and Answers] Aimless Rambler:
Need a little more information to go on. With what you've provided all I can say is to insure you downloaded the correct Odin flashable rom for the Galaxy Amp 2 and have researched (Googled) how to use Odin (proper ticks checked, etc.). It wouldn't hurt also to insure you have the latest Odin software. Also, when it failed if was there any particular error message noticed as well.
[General Questions and Answers] jasperjax:
You should also try making sure your Samsung drivers are current, may even be a good idea to just reinstall them just in case something may be wrong with them (normally causes the device not found issues but not taking any chance) also try a different USB cord. I do know not all use cords are made equal. Even a different USB port on your computer can make a difference. Then you got the common things like while Odin is doing it's thing let the device sit there don't touch it move it heck dont even look at it. But this just a broad kinda fix most issues kind of deal. Like Aimless Rambler said need some more info to narrow it down.
