Hi all,
I own a P907 for several months. When purchasing I thought I can flash a custom recovery and flash any rom I want.
It seems the AT&T Bootloader is unchangeable.
I had an idea…
I hard briked my LG D855 (G3) and brought it back to life with a procedure I found on the XDA forums, JTAG, writing directly to the board (needed to open the device).
Is it possible to write directly to the board and then it will be possible to flash a custom recovery?
Thank you.

P907A and P905V acutually are identical tablets but bootloader is locked by provider, P907A is from AT&T, P905V is from Verizon.
As long as bootloader is locked, you cannot flash different firmware to your tablet. Try to flash by Odin, you'll see it fails immediately.
I can swap mainboard of P907A to a P905V tablet or vice versa without any problem because the hardware is identical.
The P900 Wifi version, bootloader is not locked, you can flash whatever firmware you want.
I was wondering the same thing about my P905V. Would a hardware flasher work to write the P905 bootloader to it? It's such a shame that this very expensive tablet is stuck on a bloated and outdated Android version. At this point, it's so slow I wouldn't mind risking destroying it to try to get CM14.1.
Has anyone tried this conversion?
any updates on this matter ? as i would like to install any ROM with android 7 / 8 or 9
Hi guys,
I was hoping someone could help me out. I have rooted before (long time ago) but I can't seem to find a lot of information on this specific phone (SM-J727S). I have been searching online (and across many dodgy looking websites, thanks No Script!) and this is about all that I have found:
The Galaxy J7 is also known as the Galaxy Wide 2 in South Korea
http://pdadb.net/index.php?m=device&id=11601&c=samsung_sm-j727s_galaxy_wide_2
It was released on May 2017, runs Android 7.0 (Nougat) and uses the Exynos chipset
TWRP has a release for the J700 series but I'm not sure if it would work on the J727S
https://twrp.me/devices/samsunggalaxyj7exynos.html
The source code for the system has been released, but I couldn't find a stock ROM (which made me reluctant to try TWRP)
http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=j727s
This is the closest I got to a Stock ROM but I don't trust the site, is this site trustworthy? (again, I came across too many dodgy sites to just download anything)
https://stockromupdate.com/2017/07/26/stock-rom-sm-j727s-samsung-galaxy-wide-2/
The KingRoot method currently will not work and is asking me to wait for an update (phone is probably too new to root?)
The closest thing I can find on this forum are these posts (but none reference the J727S model)
https://forum.xda-developers.com/galaxy-j7/development/root-sm-j727p-galaxy-j7-perx-td-lte-t3611202
https://forum.xda-developers.com/galaxy-j7/help/root-sm-j727p-galaxy-j7-perx-galaxy-j7-t3598117
So, I'm hoping someone could point me in the right direction. Thanks in advance
I'd thought I'd mention that the bootloader is unlockable in this phone. I had read elsewhere that other people cannot access the 'OEM Unlock' option on their version of the J7. It isn't the case with this phone
https://forum.xda-developers.com/galaxy-j7/help/galaxy-j7-pop-galaxy-halo-t3647805/page2
I also got a message from Google talking about my accounts being accessed by a 'J7 Pop'. I guess the Galaxy Wide 2 is also known as the J7 Pop?
So, I'm still on the track of rooting this device. I'm just gonna update any relevant stuff here.
The closest TWRP that I can find is for the 2016 version of this phone, it has the same Exynos chipset.
I'm thinking of trying this, but are there any problems with flashing the wrong version of TWRP? (Will I brick the phone? Or will it just error-out on recovery and boot normally?)
https://twrp.me/devices/samsunggalaxyj72016exynos.html
I also found (what I believe to be) the Stock ROM for this type of phone, you have to sign up to the site in order to download it. It is specific to SK Telecom (Korean telecommunications provider)
https://www.sammobile.com/firmwares/samsung-galaxy/SM-J727S/SKC/download/J727SKSU1AQD6/172065/
If someone can advise about going forward with the similar TWRP version I'd appreciate it. Cheers!
EDIT: Kinda answered my own question, from the TWRP download page https://dl.twrp.me/j7xelte/
Downloading an image for a different device, no matter how similar, usually does not work.

Any way to request an TWRP version?
I am Korean, and it's very hard It's angry me............................
XDDDD I'm from South Korea too and the J727S is customized with the Knox Enrollment Service that blocks the wifi and cellular data AND apk installization. (trying to uninstall it )
I found this: https://www.androidinfotech.com/2018/02/root-samsung-galaxy-wide-2-sm-j727s-nougat.html
anyone habe twrp for this model ????
Hi.. I've this model also.. tried to downgrade..but it can't..always failed
My friend was installing the twrp to root a J7 metal.
Now the cell phone does not restart, and I do not know what the **** it did KKkkkkkkkkkk
It wants to remove the twrp without formatting the device.
If installing the original rom by Odin using home_csc does it return to normal without formatting?
Restore

Hello all,
I got a ZTE Grand X view 2 (K81) tablet from virgin Mobile in Toronto, Canada and I have the sim locked to my imei number. I would like to root this tablet so I can remove unnecessary applications. It is slow as it has <1gb and the internal memory is 8gb. So far the one click root apps I have tried (kingroot, iroot) don't work. What are other options I have for this device?
It is running Android 7.1.1 with the June 1, 2017 security patches
Thanks Karl

One-click root apps won't work. You either go the Magisk patched boot way or Custom recovery + Magisk / SuperSU zip.
What's your phone's chipset?

Honestly I don't really know what the chipset is. From CPU-X, here are some more details:
Cpu: cortex-a7 snapdragon 210, 1.1ghz x 4
Board: Helen
Hardware: qcom
Model: K81
Brand/manufacturer: zte
Bootloader: unknown

Its Qualcomm. To root, you'll need either stock boot.img or recovery.img. Do you have the firmware for your model?

I don't have that yet, I will need to search for that. My SD card is currently set as an internal, not portable, is that a problem? Is there a way to copy the current boot.img or recovery.img from a running system? I have installed magisk manager, I just need to get a hold of the boot or recovery files

Have you had any luck finding firmware for this device.... i need to frp bypass mine as i bought it online and am left in a predicament now... The keyboard doesn't allow to access any settings so getting through the FRP part is an issue... no way to downgrade the firmware either because it is running 7.1 . I also can't find custom recoveries anywhere i look online.... if you have some insight or a solution please let me know.
thanks

Not yet, I switched my SD card back to portable and tried to look around the system using adb shell without any luck. The system is locked down tight and I don't have permission to view most directories. I also contacted ZTE for the recovery img, they thought I was talking about backing up photos
I have same tablet from virgin mobile Canada. I have solid explorer, and it allows me to have root file access out of the box. I deleted bloat apks, was gtg. Not sure if it's normal behavior. I was shocked to see root file system out of the box. P.S any developers that a full system dump would help, I can probably do. After more poking around, I don't have full root access, but I do have read/write to system folder with build.prop etc

I just downloaded and installed solid explorer and the classic versions. Not luck viewing the / file system. If you can get the boot file and post a link to it that would be helpful for the magisk rooting method.
-I was able to use a google account manager app and downloaded/installed qucik_shortcut_2.4.0 this allows you access the launcher and partially use this device... I was able to set the username of the device but to no avail i am unable to use that combo to strip out the previous user's information. there's a method online to show you how to use the talkback settings to get to this point and i used my knowledge of frp bypassing samsung devices to get a little further. the developer options setting is still locked because it doesn't recognize me as the primary user. Its very frustrating. I'm able to sign into chrome with my credentials and access gmail through the browser but as far as getting my account onto this device its been days of trying and my girlfriend is just disgusted with my persistence. I don't know if or when an oreo update will be made available that this will help solve the problem, but i can't believe zte doesn't have the stock firmware anywhere online.
any of you fellow nerds out there that can help please do... I use an S3 for my daily use because well, they're so amazing to customize but the battery is crap because its so old. One thing i have found is with this zte you can at least play the "catch the cat" easter egg game, which is a complete waste of time but fun at the same time.
I'm not sure if this will help but i might as well. I'm also stuck with a zteK81 i'd REALLY love to root. I never had to go really deep into android stuff so tbh ... i've read alot ... but beside knowing i can't root it yet after a couple diff. method... im a bit confuse in all that. Up here i read ppls about looking for the Firmwire and someone else searching for the root. I have pull some pretty deep layer files in mine that may .. may not help you guys. I can't read that correctly. Here's 3 images and i have a little 7z with the actual files and 3-4 more if someone request it. Thanks.

I have a copy of the stock ROM. Who knows how to use it to develop a custom recovery for the K81?
Continued Interest
Is there any interest in rooting the ZTE K81?
Currently, I have a copy of the stock ROM and am trying to modify update.zip using Magisk to mod the boot.img file. I heed help with the signing of the modified update.zip package.
Any Suggestions?
There's no way of flashing an unsigned rom?

Sadly, no.
Difficulties
To date I have found no way to even perform the OEM Unlock on this device and none of the available rooting schemas are of any use.
If I cannot determine how the sing the modified update.zip file, I am out of ideas.
I have a copy of the ZTE stock rom for the K81 and, if there is a more experienced person willing to take a shot at this, I will happily make the rom available to them.

Hello, so it is common that ZTE's don't have any form of fastboot. So your only way is to flash via QPST with a firehose. But today is your lucky day. I was able to extract the k81's firehose from the Rogers ZTE firmware flashing tool. I have also downloaded the full QPST firmware fire and included the firehose with it. As well as a separate download in case someone already has it. I will also be ordering the device shortly. If you have newer firmware, or one designed for a variant other the rogers would be great if you can share it.

Where do you get or how do you create the rawprogram0.xml file. Presumably the directory structure information is available somewhere in the kernel or the ROM but, methods to extract the information into an XML evade me.
Hi all, I'm relatively new to the Android world and seeking help from experts here.
I recently bought a used S7 (SM-G930K), it came with Android 8.0 and I want to downgrade to 7.0.
I tried downgrading using its stock firmware with Odin. Attempted many times but only realized that it can only be downgraded as far as the bootloader version goes.
Think my S7 was on bootloader version 2. So as checked for the available stock firmwares, the "earliest" version 2 was still on Android 8.0 (PDA G930KKKU2ERJ1 and CSC G930KKTC2ERJ1).
Anyone can advise me how to go about downgrading to Android 7.0? Though this S7 may not be my primary phone and there's obviously no warranty, I won't want to brick anything.
Do I have to downgrade the bootloader version to 1.0 first? And how do I do that?
Apologies, do excuse these noob questions, I'm not familiar with many Android terms. Cheers!
Model: S7 SM-G930K (KT Telco)
Android version: 8.0
Baseband version: G930KKKU2ERJ1
Security patch: Oct 1, 2018
Basically, on Samsung phones, once you upgrade your bootloader, they put a lock on it, so you can never downgrade it, for security reasons, of course.
The only thing you can do is flashing custom rom, or stock rom with custom recovery & kernel.

I see, now i understand why..
"Custom roms" - does this mean it's made by users like us? And what does "stock rom with custom recovery & kernel" mean?
Can you point me where can i find these roms for my S7? Is it the same as flashing them on Odin?
Many thanks!
Yes custom ROM's are community made. The kernal is kind of like the foundation that sits beneath the ROM, so you can use the official ROM but run a custom kernal to tweak phone behaviour.
Flashing ROM's involves using TWRP instead of Odin. If you're going down that path I would recommend you read very carefully and educate yourself, instead of just gung ho'ing it. Wouldn't want to brick your device.
It's also worth mentioning while you can flash an older custom ROM via TWRP, that doesn't downgrade your bootloader with it. Having a newer bootloader on an older ROM can cause issues.
Most custom ROM's are also made for G930F, while some also support the G930K you may want to make sure before flashing anything.

Definitely will be more mindful as rooting does involve some kind of risk of bricking my phone.
Wow that's great info, really appreciate you explaining this to me.
Something new I've learnt! :good:
I would like to increase the storage space in the root location of my phone. I have rooted my phone with magisk.
Yes, you can repartition the /system partition. Not only is it quite difficult and risky to perform it, it also requires specialized skills which the average user may not have. There is one solution to the problem though: Flash a Custom ROM.
I would love to flash a custom ROM but can't find any for my device. I have an Infinix smart 5 (x657c for the model)
Even a Custom Recovery like TWRP actually isn't available for this phone.
But you can try to make it at your own because phone is based on Mediatek chiset:
Firmware Care
FirmwareCare is one of the ideal firmware download websites, serving Stock Firmware (ROM) for 343 Mobile brands in the World. The Stock Firmware shared on the website came with the Driver, Flash Tool, and How-to Flash Manual.

Due to the unpopularity of Infinix (&Tecno) phones, there's no custom ROM available for your device. Nevertheless, you should absolutely be able to flash GSIs [I WILL NOT BE HELD RESPONSIBLE FOR YOUR ACTIONS, ONLY SUGGESTING!], because I'm sure that device is Treble-supported.
There're tons of very similar Infinix phones (Smart 4, Hot 8, Hot 9 & 10 Play) that have GSIs successful installed, you can check them out on YouTube.
