I am planning to buy one of these tablets to tinker with. After some searching, I found the following rom alternatives:
http://www.arctablet.com/blog/forum...-firmware-version-1-04-test-version-20130723/
http://www.slatedroid.com/topic/91121-tempestu39gt-roms-v0001/
http://www.slatedroid.com/topic/89434-custom-firmware-from-4pda-based-on-stock-104/
Do you know of any other worthwhile rom to try out, or are these three all that's available?
Anyone?

thanks for sharing, gonna try the TempestU39GT
There's also 1.05 multiwindow rom that some say is better than stock 1.04, download is here :

Do not buy the Cube U39GT-3G version of this tablet, I ordered one from http://www.cube-tablet.com and it came with a wrong IMEI number. I cannot use any SIM data card because of this with this tablet.
I bought the Wifi version, so I am not in danger. Thanks for the warning though, it certainly speaks of extremely crappy QA.
racht: anytime, and thank you for the link to 1.5.
It seems like another rom might be on the works:
http://www.freaktab.com/showthread.php?8204-Are-there-any-worthwhile-roms-for-the-Cube-U39GT
Apparently it will be based on stock 1.04 instead of 1.05, but if it comes to completion it might be worth it to try it out.

ROM has been uploaded yesterday but the dev doesn't own a U39GT. So anyone willing to test can do it now
I can't believe that slipped by me. Thanks for the heads-up. :good:
http://www.arctablet.com/blog/forum...2-custom-root-firmware-version-1-06-20131123/
This looks promising as well with 1.06 Cube firmware update and AOSP launcher.
New original Cube firmware 1.06 is downloadabl from official cube site.
http://www.51cube.com/ch/DownShow.asp?ID=205
I can recommend Google for translating the chinese, you can download the ROM from baidu which could take a few hours.
Awesome, thanks for the heads-up.
They require registration to access the downloads? Dammit, I refuse to create an account just to go and download something. Do you have an account there, locutus2000? If so, would you be willing to mirror it somewhere?
I was able to fix the IMEI issue, so it is safe to buy, again. The support from the vendor was not helpful, the wrong IMEI number is not only wrong for me but for all of the sold models. They all have 111111111111111 as IMEI number, no big deal with the MTK Droid Tools I was able to load a new IMEI, that was generated from an internet site. It works with the SIM cards now.
Important to know: the Cube 9 Talk with the 3G SIM card uses MediaTek MTK8389T CPU whereas the Cube 9 without the SIM card 3G feature uses a RockChip RK3188 CPU. The ROMs are not interchangeable.
So whatever issues you may have, it may be a completely different story for the person that owns the other chipset. Strange enough that Cube built two similar products with completely different hardware.
The Cube U39GT 3G ROM Version 1.03 for the 3G version can be found here:
http://www.51cube.com/ch/DownShow.asp?ID=206
If you have donwloaded and unpacked the firmware, you may end up with chinese folder names. Flash tool did not accept the scatter file when I tried to select it using these folder names.
To resolve this: Simply create a new folder name and copy/paste the ROM of the Cube to the new folder, the update should then work with the Flashtool. I have used Version 3.1328.0.183. The update takes a while so be patient. Worked with mine.

Thank you for important info, I have 3G version too. And how did you succeed root, can you give me any advice?
Just wondering if it is possible to spoof your phone model (in build.prop or elsewhere) to make a particular phone work on a particular carrier.
i.e. Huawei phone on Verizon
How does a carrier know which phone you are using?

Regarding your last question. It's read off your device and transmitted to the carrier.
To spoof/fake I actually only know one tool that I'm using myself but the device must be rooted and also running Xposed. The latter means the ROM must be Oreo or lower as Xposed isn't available for Pie; second with Xposed installed you're never going to pass the SafetyNet check if you require that. Finally, depending on your ROM version use XPrivacyLua or XPrivacy, both by M66B, and I always suggest the pro version to mainly support the developer and the development but also to enable some additional, useful features. XPrivacyLua has a companion application.
Hey all,
I got this unlocked GSM phone from a very large online retailer and I would like to put TWRP on it and also flash a custom ROM and possibly gApps if possible. I came across a guide telling me to download an app to determine if the phone supports project treble, which it does not as it was upgraded to Android 8.1.0.
When these devices are advertised as unlocked I assume it relates to being free to use on any carrier using that particular network, in this case GSM? Also, this does not mean the bootloader is unlocked?
I am having difficulty in finding the correct version of TWRP for this particular device as well as compatible custom ROMs and I am not even sure that this is the correct forum to be posting in for my device as I didn't see a Phoenix 4 forum. Please help.
Any chance a mod could transfer this post to the correct forum?
I been trying to root my Samsung Galaxy A52 5G but in order to do that i need to unlock the bootloader. So i follow the instructions and tells me to toggle the OEM option but i don't see it in my phone. Can someone please help.

again, assuming you have a usa model (buying from samsung doesnt answer that question unless you say you bought a usa model from samsung meaning its a U1 model) then your bl cant be unlocked without paid service and you will not have oem unlock toggle at all
I said yes, can you recommend someone? Or where I can find them?

most of those are for international devices that are unlockable where there is a 7 day wait period and doesnt apply to usa models at all.. usa models are NOT unlockable.. that site even thinks you can create a factory/combination firmware by using stock firmware which is also bs lol

I Participated myself to this long discussion in this thread and the conclusion is that : IT DOES NOT WORK for the Galaxy A52S 5G !!!

Arobase40 said:
At present time we are all on the same boat for the A52S 5G USA or International models as this phone is not really unlockable even when the system pretends it is unlocked !
My OEM toggle is ON and when I turn my phone on I got a message telling me exactly this :
"This Phone's bootloader is unlocked and the software integrity can't be verified. Any data on this phone may be vulnerable to attackers. Don't store any important or sensitive information on this phone.".
But whenever I try to flash a patched AP file with Magisk my phone goes into a bootloop !!!
I tried different methods including creating a "custom ROM" with modified AP and BL files and the result is just the same : bootloop !
For what I know there is something related with the Samsung Vault Keeper mechanism and I'm trying to find out a workaround for this, with no result ATM...
So the purpose of my previous link was to fix the missing OEM toggle button, nothing else... But I guess this option may also be not available anymore with this phone... At least you can try...
On my side, whether I unlock or re-lock the bootloader (in Download mode) the OEM toggle button is always on... ^^
So I guess the unique solution should be to create a petition address to Samsung to put the pressure on this dam*** company ! ^^
I used to love Samsung products but this company's policy is driving me nuts and it makes me more angry as time goes by...

I am not sure what that has anything to do with the OP or this thread. Your bootloader is clearly unlocked. Because you dont know how to root it doesnt mean your bootloader is locked as well as doesnt help the OP at all since his model is a usa model and cant unlock the BL like you can.
You will likely confuse people by trying to hijack the thread to solve your own issues that are unrelated to this thread. Just saying.

both of those are unlockable and rootable but the op in this thread has a A526U or A526U1 so you both are in the wrong thread lol none of that will work on his device and sibce hes not unlocked and cant unlock in the first place he cant flash any custom firmware at all.
What is the KG or RMM state after you unlocked it? So to be clear, you unlocked the phone, booted into download mode, flashed the pached boot file, rebooted phone, it does not work?
So I'm coming to a conclusion that this phone is unlockable. Right? Right! Oh well thanks everyone for your help and support. Much appreciated.
Arobase40 said:
You're right on one point is that my post has nothing to do with OP but it was just a response to your own post... ^^
I'm here on XDA over 10 years and I always rooted my devices and I also saw different US Samsung devices being unlocked after a certain time...
So it's not a matter of hijacking the thread to solve my own issues but just a conversation to explain the situation of both A52 5G and A52S 5G whether from USA or International model...

a response to my own post saying the links provided likely only applied to international variants and NOT to the usa models and therefore are irrelevant doesnt mean its ok to confuse ppl and hijack a thread to try and solve your own problem lol..
It is hijacking because the international models and the usa models are very different when it comes to unlocking the bootloader.. USA models cannot unlock the BL whereas Intl' models can.. you can unlock your bl but dont know how to root it which is completely dif. than the ops issue who cant even unlock the BL.. the "situations" you are trying to explain are completely different.

you are wrong bcuz u are going based off all the intl models being same as usa models which they are not so any solutions you have based on intl models will not work as they dont apply to usa models.
Arobase40 said:
I don't understand why you are globally locked down with the US models and what you are saying is false and you know it as you are also the same moderator in the Galaxy Note 9 thread !
It took more time to unlock and to root the US Note 9 than the International one but at least it is now possible to unlock the US bootloader and to root the US Galaxy Note 9, including installing TWRP (since 2018) and some custom roms. You also proposed a way to root the US Note 9 without the need to unlock the bootloader and to touch the Knox flag. Partially useful but the problem is that you cannot do TWRP backup and restore when something is wrong... This was the same problem with my Galaxy Note 3 and with every firmware updates I had to redo the whole process from start to root it as there was no TWRP available at that time...
There may be also some other US Samsung devices in the same position such as Galaxy S10e (SM-G970U) but I don't own them and I don't have time to check all their situations...
I saw also TWRP for the US S21 Ultra and the US Galaxy Tab S7 Plus... based on your signature...
BTW, the OP issue is that he can't even try to unlock the bootloader simply because he can't see and can't access the OEM Toogle !

- USA Models have almost always been locked down. A few variants were unlockable for a bit like tmo or sprint but for the most part for years and years us models havent been unlockable without exploits and even then a majority of said exploits were just for root (bootloader was still locked and not able to use TWRP.)
- Not sure what you mean about Note 9 because I dont moderate in Samsung forums, I mostly am mod for Xiaomi. If you mean my root exploit for N9, that is using exploits and only for root, not for unlocking the BL.
- There was no way to unlock the bootloader of the US Note 9 in 2018. I posted the worlds first and only Note 9 root exploit which BL was still locked at that time and no option to unlock and use TWRP so I am not sure what you are referring to there.
- As I stated earlier I believe, devices released in 2019 to current (S9 to S21 and even some flip/fold devices) up to a certain update (each device is dif. but newer security isnt possible) via paid service which I also provide (and one other person) that relies on a device specific "token" that unlocks the bootloader. Even then, the oem toggle is never visible even after unlocking via paif service if it can even be unlocked (meaning its not updated to the point it cant unlock anymore.)
- My S21U did have an unlocked BL until I was robbed at gunppint and thethief broke my screen and upon getting it repaired theyhad to update it to latest firmware therefore losing my unlock. And the Tab S7+ that I have isnt a us carrier model (which are not unlockable without paid service) and is a SM-T970 (wifi only model) which is BL unlockable out of the box unlike us carrier models.
- Lastly, that is exactly what I am saying. He has a USA model that is not unlockable without paid service (if hes not updated to a firmware it no longer would work on.) The oem toggle will never appear. Theres no 7 day trick or anything he can do to get it unlocked. He'd have to find some sort of exploit that no one in the world has found yet or that they havent released (if someone did find some exploits.)
This is coming from someone who knows many devs around the world and as of last few years seems to be the only one still actively searching for exploits (and even found some root exploits and other things) and that only buys US models that are locked down tight and currently working with s21u a50 a32 5g s20u with no luck even at a root exploit. I was simply just trying to put it out there so ppl dont waste their time and stated the links and such ppl posted are irrelevant in this case as they dont apply to us models but hey, you can think I am wrong if you like and I hope op finds a miracle somehow to unlock his BL as itd help me unlock my other devices and others in the same boat but I'll take that with a grain of salt lol.
Hopefully this cleats things up for you.

Because this isnt your thread and the ops issue is completely different than your issue and US or intl model DOES matter because you are unlocked.. US model cant even get that far.. your issue is with not knowing how to root after your bl is unlocked.. ops issue ishe has a US model and cant unlock the bootloader at all.. talking about your issue confuses people with US models into thinking they can unlock their bl but they cant so two different issues...

First of all I have to say English is not my native language so I can say things that can be misunderstood, but since now I don't think this is the case...
I never said or meant that US and International Samsung phone are the same or could be treated the same way nor did I said that ALL US phones could be unlocked, but as you said yourself : "A few variants were unlockable for a bit like tmo or sprint but for the most part for years and years us models havent been unlockable without exploits and even then a majority of said exploits were just for root (bootloader was still locked and not able to use TWRP.)"... ^^
Then it's hard to know when you participate into a discussion as moderator or not as you always use the same pseudo with the same status "elliwigy : Forum moderator /Recognized Dev / Dev Relations"... ^^
But when we go in the Snapdragon dev section for the Galaxy Note 9 your name appears seven times in seven threads... Excluding the open thread where you explained how to root the Note 9 with an exploit.

About unlocking the bootloader of the US Note 9 in 2018 I was indeed confusing with the SD 9600 which is a Snapdragon but not for the US model... ^^
But if you go to this following thread OP, did say the US Note 9 could be unlocked with possibility to install TWRP and it was by May 6, 2020 even if the title mentioned N9600 !!!

Finally, you admitted you owned a "My S21U did have an unlocked BL"... So what should we think about your own words ???
In regard with my own International A528B phone I did the unlocked process and tried many times to install a custom AP file with Magisk but it didn't work as my phone enter into a bootloop process after flashing it via PC Odin. At last resort I relocked my phone and I was surprised to receive an OTA update which should be impossible if my phone was really unlocked !!! ^^
How can you explain this ??? lol

- My "pseudo" as you call it is a tag/status. I was a "recognized developer" before I became a forum moderator and before jpining the dev commitee. It is tags that every forum moderator receives so ppl can see who the mods are. I am still a developer. The way it is broken down is each device has its own set of moderators which you can usually find a list in each section usually its stickied forwhichever moderators can moderate that section i.e. I can moderate xiaomi forums but since I am not a mod for Samsung I cant moderate in Samsung forums. Rule of thumb though, if you see I have created a thread in say Samsung forum then that is me posting something I have developed or am developing i.e. N9 root method and obviously posting as a developer. You would know if I was posting as a moderator as it'd be saying something in regards to moderation i.e. cleaning a thread for bad language or off topic banter of which I would have deleted/removed comments or some sort of action or if responding to a reported post etc. etc. So it would be clear if I was posting as a moderator as I would make it clear.
- The snapdragon dev section in N9 forum is for all snapdragon models of the note 9. The N9600 is the Korean variant if I am not mistaken and is unlockable by default. The OP in this thread has a USA variant, I did not say all "snapdragon" models were the same. ai simply stated "US/Carrier Models" were not unlockable without a paid service. Since N9600 is not a US/Carrier model it is unlockable and is in that section because it has a Snapdragon chip in it therefore falls in the category of an international model that is unlockable by default and therefore unrelated to the discussion here. The korean variants typically end with a 0. Models that are not unlockable are typically ending with U, U1, or W i.e. N960U, N960U1 or N960W. Anything else is likely not a US/Can model and are typically unlockable by default.
- Afaneh is the other person that can unlock bl's using a paid service which I already stated. USA models can use twrp once they get paid service (given they arent updated to a firmware not able to be unlocked) to unlock the bootloader first. This is the ONLY way to unlock the bootloader. He also makes twrp builds for devices and clearly (as you also included in your link) he is clear that you need to use a paid service. As for that other twrp post I have no idea. Because someone posts in a Snapdragon section and isn't specific on which variants it is for is not against any specific rules. I can bet however without even looking at it you can likely read the comments and see people with US models saying it didnt work or asking how to unlock the BL because it wasnt possible. Typically in those threads the dev will indicate you need to unlock the bootloader first and US variants cannot unlock the BL therefore that TWRP wouldnt apply to them at all.
- As far as your issue, the fact that you could successfully flash custom firmware using ODIN tells me you were unlocked. On locked devices (i.e. US variants) ODIN would fail and device will say an error so they wouldnt even be able to get that far. Samsung always likes to be different in how android and root and stuff work. Sometimes magisk needs to be modified or tweaked to work and sometimes the install instructions vary by device. I cant help you there because I sold my N9 before was able to unlock the bootloader but can guarantee you are able to root your device since bl is unlocked you just have to find the right instructions and follow them to the T. I do not know the steps for your intl model so I cannot say why its bootlooping but I assume you are missing a step somewhere.
As for relocking and getting an OTA, it is possible even if you were still unlocked. OTA will not work however if anything is modified i.e. if you are rooted the ota will fail. Simply having an unlocked BL you can still get an OTA if you havent modified anything i.e. no twrp and no root and no modified rom etc.

First of all, when I posted a thread with a link on how to unhide the OEM toggle I said "Maybe you can try something like this ?" and nothing in the link mentions it was an International model !
And at present time nobody can certify my A528B phone is really unlocked as I was able to relocked it and I also received an OTA update which would be impossible if my phone was really unlocked !!!
That's why I said we are on the same boat... at present time... ^^
In regard with US bootloaders I gave demonstration it was possible to unlock some of them with different Samsung phones and I never said it was possible with all of them but sooner or later it is possible to unlock some of them whatever the process with or without paid services...
Ok, I'm now done with this discussion.

I said it was irrelevant because it will not work as usa models cannot unlock the BL. A lot of those sites will not list specific models and assume every model is the same andsometimes even use old pictures/instructions for super old devices and just create new pages. I bet most samsung sites like that all have same instructions word for word and only difference is the name of the device lol. I dont know why they do this but they obviously dont know what they are talking about,dont care or the page creation is somewhat automated but rule of thumb is us models cant unlock so you can assume those pages do not apply to us models.
Again, you can get an ota if unlocked and on complete stock firmware hence doesnt mean anything really. To add, just the fact alone you can toggle oem unlock and unlock your bootloader and were able to successfully flash a modified firmware in odin says you were unlocked as it would have failed in odin and not flashed anything. The fact that you bootlooped aftereards doesnt mean you werent unlocked, just means theres some steps you are missing or the files you used were no good. This also means you are NOT having the same issues. I dont know why its hard for you to understand that op cannot unlock his bl at all, doesnt even see the oem toggle (and never will) is the same as you who can see the oem toggle and can unlock bl and can flash modified firmware but bootloops afterwards as being the same issues.. OP can only hope his device isnt updated and can pay for paid service to unlock whereas you need to find proper instructions on rooting your device and to avoid a bootloop.. two completely separate issues.. You might have initially thought they were the same issue but that is why i clarified multiple times they are not the same issue at all and you even have a completely dif. variant than op does.. If you still think they are the same issue then i dont know what to tell you at that point and hopefully op realizes that he can only unlock with paid service and isnt confused as you are.
And yes, some us models were unlockable years ago.. In fact, I believe the S4 verizon models could unlock using an exploit on a certain firmware and verizon note 4 could unlock using an exploit turning it into a dev device but outside of that it has not been possible so if you are saying some could be unlocked going based off devices that came out years and years ago then sure. Recent years/devices though it has not been possible.
The paid service technically uses an exploit that creates a "token" that sets device to allow custom firmware to be flashed (essentially acts like an unlocked bootloader) but isnt unlocking the bootloader in a traditional sense at all so one could argue it isnt exactly the same (although result is the same.)
I read on a forum post that technically its possible to make LG G5 VoLTE compatible? How would someone go about this?
It's not unless you are on stock or use a stock based rom. The drivers needed for VOLTE are locked down by LG and cell Carriers

You need root, and european cust files.
Make a clean install and put the open com files in the cust folder/partition which can be found in root. Make a few adjustments, got to the hidden menü and find the ux lte settings and turn the first 6 switches to on.
For deeper information you can ask here but all of this i formation can be found in this forum.
