ME176CX - root and replace ROM? - MeMO Pad 7 Q&A, Help & Troubleshooting

Hi folks.
Been rooting and replacing stock ROMs on android tablets for about 3 years now (usually cyanogenmod). I just ordered a ME176CX.
Can the bootloader be unlocked? Can cyanogenmod (or some other android flavor) be installed?
Thanks.

There is no known way to unlock the installed bootloader on the device, although there is the theoretical possibility to boot a custom bootloader on the device. Making that work, however is quite complex and requires low-level knowledge. Because of this, there is also no CyanogenMod available for this device.
Rooting is easily possible, however.

[Q] Why unlock bootloader on non DE when we have safestrap?

I've safestrapped a rooted 4.4.2 rom on my AT&T locked moto x for quite some time and I can't see any real downsides.
I even had a look to see if it's possible to flash non-stock roms with it and from what I understand it's totally possible.
So my question is: What's the point of unlocking the bootloader on non-DE devices (with, say, the chinese middleman method, which costs about 40-50$), when you can simply bypass the protected /system directory by using safestrap?
If I understand though, the only real limitation is that we have to wait for the sbf of the newer versions of android to be released for our specific device, in order to flash the correct kernels and all. I think.
Please correct my statements as they may be wrong, and thanks for your replies!

Once you have updated your CORE SOFTWARE (and bootloader) to 4.4.2, safestrap is useless. The 4.4.2 bootloader is impervious to known write-protect-disable exploits.
Many people updated to 4.4.2 without reading the consequences and now BL unlock is the ONLY method to achieve Root AND Write-protect-disable.
Additionally, the process is much more streamlined and far less complicated than installing and configuring safestrap. Simply unlock, and flash TWRP. Done.
Also, non-stock-based ROMS (AFAIK) cannot be used with safestrap because as I understand, it uses an "overlay" technique which would not work on a non-stock-based ROM.
Good Luck

Also, using safestrap takes up more space on your device, since you have an underlying core OS (as samwathegreat puts it), essentially meaning that you have two full ROMs on your phone. If you have the 16gb Moto X, that will suck up a good chunk of space (though that's not the end of the world). If you have the 32gb version, you are probably ok. I agree with everything else samwathegreat says though.
Thought I would add my two cents in here as someone who ran safestrap for a while before getting my bootloader unlocked through the guy in China. First, a small correction, running safestrap doesn’t have to take up much/any more memory as you can flash the ROM to your “stock” slot. As of right now I believe the other slots are not even working. Now, as for why unlock your bootloader, I think there are a number of reasons. Yes, you have an up-to-date ROM on your phone currently, but you are going to be dependent on a dev making a safestrap compatible ROM for any new software releases. This may or may not happen. You are at the mercy of the few devs who are currently doing this. That is probably the biggest reason for me deciding to unlock. Another reason, as samwathegreat stated, is I do not believe you can run AOSP ROMs currently on safestrap. If it works like it did on my old Droid 4, you would need to use something like the kexec exploit to in order to flash custom kernels in order to run an AOSP based ROM. I haven’t seen anyone working on anything like that. The last big reason I can see is safestrap does not seem to be in active development on the Moto X anymore. Numerous other devices have seen safestrap updates recently (including the Droid 4) but not so the Moto X version. I would definitely recommend unlocking. I know I’m glad I did.

thanks for making things clearer for me, and everyone for taking the time to answer my question.
as i've got a 2013 model I guess I'll just have to hope that safestrap supported roms will keep being released for the moto x for future updates!
OP - long story short:
locked bootloader = some dev/hobbyist, etc finding a security flaw in the system that exploits the ability to obtain root (and hopefully system r/w).
Requires an adoption rate from other users.
Is only as "reliable" as the device is relevant.
Exploits have the potential to insert malicious code.
unlocked bootloader/dev edition = "free range" to do whatever you want, regardless of security flaws.
Potential to extend the longevity of your device.
Rooting methods are common among most devices with DEV Edition/unlocked bootloader option.
Permanent.

I am quite aware of the difference between locked and unlocked boot loaders. My question was really regarding if safe strapping offered as much as a regular recovery. But thanks for clearing that up as well!

Any way to flash SuperSU without TWRP?

So far, every damned Cricket phone I've ever bought has either a crippled bootloader, or no bootloader at all. I recently bought the LG Harmony (M257) (Android 7.0) from Cricket Wireless after unsuccessfully trying to root and bricking a ZTE Grand X 3 (Z959) (Android 5.1.1) from losing charge while attempting a root. Either way, these phones seem to have little to no bootloader. If you prompt adb with "adb reboot bootloader" it just boots as normal, right into the OS.
My whole question here is, is it possible to flash SuperSU without TWRP or an unlocked bootloader? I am in dire need of rooting this device, as I'm getting overwhelmed with how little it can do as stock.
If there's a downloadable version of twrp that is "universal" somewhere, with a proper signature that can be adb side-loaded, or anything that can get me a team win custom recovery on a device with a crippled bootloader, please tell me about that too.
Thanks in advance to anyone that replies with helpful info!

- it has a bootloader; just crippled (like most carrier supplied prepaid devices)
- no way to install Magisk, SuperSU or similar tool on an unrooted device with locked bootloader (if it were that easy ...)

Well, it was worth a shot... Guess I might just have to resort to a few sketchy one-touch methods and use SuperSU Me.

Good luck - no known (or at least reliable) root exploits for M257 which is a prerequisite for SuperSU me.

v21: Root/Unlocked Bootloader + TWRP?

Hi! When I got my R1 HD, I wanted to get Lineage OS and TWRP. I tried everything including:
adb "fastboot oem unlock",
SP Flash Tool, and
DirtyCow R1-HD Tool,
yet I found no luck. Does anybody know how to get an unlocked bootloader and TWRP on an R1 HD v21? Thanks!:good:
P.S:
My "Custom build version" is:
BLU_R0011UU_V21_GENERIC. Also, this is not the Amazon Prime variant, however I got this from Amazon (for example: I get no ads).
Sorry to tell you, but version 21 of the ROM cannot be bootloader unlocked or rooted. The more recent updates have secured the phone so that none of the previous methods you mention work anymore. The phone is no longer being manufactured and Blu does not provide a process for unlocking the bootloader as some other companies, like Motorola, do. So even though you paid more to get the no ad version, you can't root it. 8-( This was only possible in the earlier versions of both the amaon and non-amazon models.

So, can I revert back to an earlier version of the ROM where it is possible to unlock the bootloader?

no, the signed updates are incremental so, the checksum verification will pervent flashing old version
OK.... What's the best thing to do now?
I found this option in my updater that says "Local updates". Maybe this can help?

No, sorry - there is no known way to root or flash modified software after the phone has been upgraded with factory software. You can't go back. And, even if you could, it wouldn't help - it still couldn't be rooted or flash a modified ROM. Blu does not offer to unlock bootloaders the way some companies, like Motorola, do. Your phone is stuck with what you have now.
The best thing to do now? Enjoy your cheap android phone with great performance for the price!

Well, is there at least a way to skin the phone (ex: change bootanimation, remove bloatware (Yes, there is still bloatware apps, and I'm talking REMOVE the apps, no uninstall for user only), remove the Adups spyware) so that it is just like stock Android?

No - all those things require root, which you can't get. Only the phones that were shipped with earlier versions of the ROM and hadn't been updated over-the-air could be unlocked and rooted.
Related. I have an 8GB phone; Custom build:
BLU_R0010UU_V8.7_GENERIC 05-08-2017
I've been trying to install TWRP (and then Lineage) but I'm having zero luck with SPFlash. I've tried on a couple of computers and followed the directions step by step. Am I missing something here?
Thanks,
Edit: yep, saw in another thread anything above 8.1.
Imma email Blu and see if they'll loosen the restrictions if they're stopping development. Can't hurt at this point.

Copperhead Os for Moto x4?

I just wondering if it is possible to make an custom rom, of copperhead os? Or can it only be used in Google Pixel devices?

I would think not since you need to unlock the bootloader to install a custom rom.

My bootloader is also unlocked, I meant that you cannot run CopperheadOS on an unsecured/unlocked system. This is what I was referring to:
"Unlike other custom ROMs that strive to add lots of new functionality, Copperhead runs a pretty vanilla version of AOSP. Also, while the first thing you usually do when playing with a custom ROM is to add root access to the device, not only does Copperhead prevent that, it also requires that you have a device that has verified boot, so there's no unlocking the bootloader. This is to prevent malicious code from getting access to the handset."

How to flash a ROM without unlocking bootloader? - This is a Question

On AliExpress on almost all listings on Huawei devices (P20 Pro for instance) there is the option to buy it with a flashed Global ROM. And they do this without unlocking the bootloader.
How do they do it? Is it that the bootloader on the Chinese version is unlocked?
For example...
https://forum.xda-developers.com/huawei-p20-pro/how-to/guide-force-update-using-firmware-t3963074
This is just a stock rom, you can download an update.zip and install it via recovery no problem.
Don't make the mistake of thinking this is a custom rom like AOSP it isn't.
It's completely stock, all P20 Pro devices come with an open OS afaik, then when you turn it on with your SIM it binds to the carrier / location, least that's my understanding of it.
But 100% not a custom ROM.

What do you mean by an "open OS"?
My Huawei device has a locked bootloader, and I didn't find any way on the internet to unlock it yet. (There is a site that offers leaked unlock codes from Huawei itself for 50$ but I won't pay this much). Consequently, so far I've only been able to install official Huawei ROMs only.
*Huawei has stopped to officially offer unlock codes since a year as of now.

You don't need to unlock your bootloader, look for the otg update method on xda.
It's quite easy.
Open OS, as in its just a stock ROM. Nothing more.
