Greetings, everyone! Usually I have good knowledge regarding rooting, custom recovery and flashing a new system. But this time I tried to downgrade the Samsung Xcover 3 of my friend and flashed the Android 4.4.4 sboot.bin with Heimdall - unfortunately I forgot to tick the "no reboot" option. The moment it rebootet, I know do not have any access to the phone anymore.
When trying to bring it into download mode, it vibrates, but nothing else. Neither Linux nor Windows recognizes the phone. Is it dead? How to gain access so that I can flash the correct sboot.bin? Any tricks you recommend?

If you can find a "debrick.img" or "debrick.bin" for your specific model number, there is a method that uses your external sdcard to boot the phone then repair it while it is booted.
But, first, you need to find a debrick.img or debrick.bin for your specific model number. If you can't find a copy for your model number, you can try finding another member here that has a rooted Xcover 3 with the exact same firmware as your device had and have them pull a copy of debrick.img or debrick.bin from their device then upload it for you to download.
If you can't find that, the only other options are to send the device to a repair shop for JTAG service or replace the motherboard.

I did not even expect that someone would answer here. THANK YOU SO MUCH, @Droidriven! That gives me hope to rescue the phone instead of having o buy a new one for my friend. Here is what I actually did wrong: In my attempt to "downgrade" from 5.1.1 Lollipop to Android 4.4.4 Kitkat (downgrade needed to be able to root the phone) I flashed the sboot.bin of Android 4.4.4 Kitkat with Heimdall and forgot to tick the NO REBOOT option.
That being said, the phone now only vibrates when using my JTAG (yes, I actually have one and the phone vibrates, but does not boot into download mode and is not recognized by neither Windows nor Linux). So, how to build this unbrick image? Could you help me with that? Both firmwares are to be found here:

Thanks a lot for your help. May god return your efforts in helping me!

Sorry, I'm just now seeing this. Did you ever make any progress? Yes, I think there are some reliable methods to create debrick.img/debrick.bin files, there is one such method posted here at XDA in a random post in a thread here but I can't remember exactly what thread it is.

Hi All,
The short of a long story is that I just changed carriers and found out way late that I couldn't bring my Sprint phone to MetroPCS. So now I'm using the budget PCS On5 that came with the deal when we signed up.
I successfully loaded TRWP and then rooted however, I didn't know about FRP until it smacked me in the face. The root went fine but later SU prompted me to update the binary and when it did, it tripped factory reset protection and soft bricked my phone.
I want to reinstall stock OS on this phone but it appears that I have a software version that I haven't been able to find on the web yet. I found the stock rom for the MetroPCS On5 easily enough but it's Revision 0.0 and the box I have for the phone says REV0.4.
When I try to Odin Flash the REV0.0 version, I get SW REV CHECK FAIL DEVICE 2, BINARY 1 fail. So I guess I had the latest software on my phone and the phone thinks I'm trying to roll back using the 0.0 revsion.
My question is this, does anyone here have the stock rom for G550T1 REV0.4? Help!
If nobody does, maybe I can still fix this phone. I have a TRWP backup from the sister phone (same model same revision 0.4) that I'm using right now but I can't get back into TRWP on the soft bricked phone to recover that way to use the backup file.
Next I thought I might take the backup files and turn it into a rom and just flash that. However, with the tutorials I followed I kept running into problems. When I went to unpack the files per the tutorial, my rar software said that the file was corrupt. Maybe it is. but maybe not. It was my first time attempting to make a rom. If I can't find the software I need, could any of you Android geniuses help me get this backup into a flashable format?
I have to admit I'm daunted by the FRS in 5.0 and above. Is it defeatable? How do you root newer Android versions?
Thanks!
I did the same thing to my phone. did you get yours fixed?> if so could you provide me with the rom?
I haven't found the fix yet. Hopefully somebody will come through with a helping hand!
I finally got it figured out! So here is what i did and hopefully it will work for you.
1. I Odin flashed a good BL from the ROM REV0.0 floating around on the net. So at least I could now get into download mode.
2. Then I used Kies3 > Tools > Firmware Upgrade and Initialisation. It will ask you for your model number and then when you click ok it will ask you for a SN.
3. The trick is that Samsung doesn't put the SN that you need on the phone or the box. (personally, I couldn't find it on the phone either once I got it up and running) so go here: https://forum.xda-developers.com/android/general/root-samsung-galaxy-on5-t3435457/page46 and get a SN from post #454 and use that. (don't forget to say thanks)
4. Click Ok. Let it work, and max and relax.
Mine took about 10 minutes. Hopefully this will work for you too! Thanks XDA!
Help!
What is BL from the ROM REV0.0? I need your help, I have the MetroPCS On5 and I installed Reborn ON5 I want to go back to the MetroPCS ROM because the camera and the audio do not work and I tried to install the original ROM through Odin but it does not work I get an error. What I can do? I would like to use this method but I do not have very clear files needed.
You could help me bro, I'll thank you
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?

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

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.

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?

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.
the boot.img file was loaded into my phone in order to get root after that it could not detect imei numbers. Although they are in fastboot. I tried many different firmwares for this phone, but there is no result! I ask for your help. I was left without communication (sorry for not being very clear. I don't understand Russian and don't understand English at all, that's why I'm writing through a translator
The first thing you want to do is STOP FLASHING random images. It sounds like you are going to cause more harm than good if you keep going.
Figure out which firmware you started on (WW, EU, CN) and get the raw firmware for it. Follow the instructions to flash the raw firmware.
If that doesn't work, then you may need to contact the manufacturer, BUT at least you will be restored to stock. I cannot promise they will help you, but it sounds like you did more than flash a boot image. The IMEI is not stored there.

Tell me where you can find the pure CN firmware? This phone was presented to me in this form already. And they told what happened to him. I doubt that ASUS support will help me, since in addition to everything according to the owner, the EMMCCDL_GUI utility was used. So I ask for help from knowledgeable people here.
And most importantly, what to flash and how?

It was opened. This is not an option either
If you purchased it used and the seller refused a return, it sounds like they were trying to recover what they could by selling their problem to someone else. It's likely they knew there wasn't a self-service fix right now.
Just to be clear, what you need is a low-level EDL restore. As it stands, one of the files required is not available to the public. If you have a local repair shop, they may be able to do it (and will likely charge a fee).
Do NOT pay someone over the internet. It CANNOT be done remotely.
So, I am currently having this Samsung Galaxy J2 TV (SM-J200BT, Android 5.1x) that I have been locked out for a couple of months now and I still have some important data there to be fetched out from the device, therefore leaving the factory reset option as the last resort. I have tried using Dr Fone and iMyFone but my device is not listed on their supported devices at the moment. I also have tried using ADB but unfortunately, USB debugging is disabled on the phone. At one point, I even have considered to apply the method which involves copy-pasting a long list of numbers and pasting it into the password field then crashing the lockscreen, but unfortunately again, the phone does not even allow me to copy nor paste anything while it is locked. I also have considered using the GSD tool to install the phone's boot.img file for this matter but the file that I have downloaded for my device seems to be unsupported or corrupt according to the software and carrying the next step into Odin just doesn't do anything either (TWRP included, since the 'galaxy j2lte' file was the closest one I could find).
The only possible solutions that I could think of, at least to some extent, that is still giving hope at the moment is to somehow find a roundabout method in activating USB debugging while the phone is locked or have a proper firmware/file that can help me succeed in installing into the phone and unlocking it using Odin or some other method, while at the same time, NOT LOSING ANY DATA. Any help or suggestion is widely appreciated, thanks in advance.

Hello
I've been reading forums and downloading files for days. Many of the links in the posts no longer work. Posts are 5 years and older. There are no new ones. At least not one that actually works. Downgrade I mean. That's why I wrote this question and I'm asking for help - how to really downgrade my Galaxy S6 G920F.
Thanks for the help.
PSA: Downgrading WILL void your warranty!
What have you already done (what method, software) have you already tried?
The 100% surefire way to downgrade your phone (or any android phone really), is to:
1. Backup your phone data.
2. Switch the phone into download mode, connect to PC, boot into TWRP recovery through fastboot
3. Wipe your 7.0 firmware and all data
4. Flash android 5.02 ROM
For a samsung phones ODIN + Freya is also an option. Odin is a samsung's firmware flashing tool, Freya is a 3rd party program that can download the stock firmware android for you. All of these tools are available online, and you can ask on a samsung subsection of XDA about how to use them - people can give you up to date links.
I'm laughing because you write quite a lot in three days. Of course, this method does not work.
Is there anyone willing to help?

PSA: Downgrading WILL void your warranty!
What have you already done (what method, software) have you already tried?
The 100% surefire way to downgrade your phone (or any android phone really), is to:
1. Backup your phone data.
2. Switch the phone into download mode, connect to PC, boot into TWRP recovery through fastboot
3. Wipe your 7.0 firmware and all data
4. Flash android 5.02 ROM

That is assuming they have TWRP.
Also, the part you mention about "boot into download mode, connect to PC then boot to TWRP via fastboot" is not correct because Samsung is not compatible with fastboot, adb works but fastboot does not. Some Samsung devices technically have a "fastboot mode" but it isn't functional, it doesn't respond to fastboot commands, it's basically useless.
Also, you can't flash a firmware that has a lower binary than the currently installed firmware so if the binary of the downgraded firmware is lower than the binary of the currently installed firmware, the downgraded firmware can't be flashed.
Samsung is making it harder and harder to downgrade their devices.
OK. I'm afraid I'm missing the point of what's being said.
I know it is possible and there are also posts about it, but they are old, the links in them do not work. I'm asking for an expert who knows how to do this, philosophizing about what it would be like if it somehow doesn't really help me and I'm not interested either
I'm only interested in a positive thought, help and not brainstorming, if you understand me?
No offense
