Phone does not Boot - Android Q&A, Help & Troubleshooting

My device is a Huawei honor 7 lite (nem-l21) with bootloader unlocked but not rooted. I was trying to install twrp, but i was not able to get it to boot twrp, so i googled my problem and found a person on stackoverflow with the same problem who said that he typed fastboot flash boot twrp.img and it worked. I did that and my phone wont start and it is stuck at your phone is booting now... I have tried using huawei erecovery but it shows the message retrieving packet information failed, and i have tried flashing stock firmware via sd card but it sais that the firmware is not compatible, even though i have tried multiple downloads of the nem-l21 firmware. If anyone will help me make my phone usable again, or tell me if my phone has any chanse of working again, please tell me.

Soft-bricked OPX, Working Fastboot, No Recovery. Need help please.

Hello guys,
I have a problem with my OnePlus X, and it would be lovely if I could get some help or advice from you guys.
> To provide some slight background, I purchased this off of eBay to complete my OnePlus collection. Most listings were above what OnePlus originally sold the phone for, but I found one for $125 in good condition by a seller with a good rating. It was advertised as soft-bricked, with Fastboot in working order. I thought "no problem, I'll just reflash it and be on my merry way."
Now onto the issue. I received it, charged it up, and attempted flashing the official recovery provided by OnePlus, but something is not working. I've been tinkering with Android for a number of years now, so I troubleshooted as much as I could, but to no avail.
1. Starting with device unplugged and powered off, boot into fastboot
2. Plugged into the computer, and ran `fastboot devices` to ensure it's recognized. After that, I flashed the recovery.img that was on my desktop with `fastboot flash recovery recovery.img` (yes I was in the correct directory). It looked successful. Picture of cmd response text at the following imgur album: /a/25DEQ (sorry I cannot post full links yet, had to create a new xda profile, forgot my old one :/
3. Unplugged the phone, powered off, Volume Down + Power to attempt boot into recovery. Failure. It just turns on with the 1+ logo, and quickly flashes the 'android' logo at the bottom. It stays like this until I manually power off.
I'm a bit stumped I have to admit. I would greatly appreciate any input you folks have. Thank you.

Which recovery u tried? Did u knOw the previous os version details?
And try this after flashing recovery in fastboot, boot into it directly by giving a cmd "fastboot boot recovery.img"

Hi! Thank you for your reply
I posted this same question on the /r/oneplus subreddit, and received a quick and helpful walkthrough. Turns out part of the problem was that the micro-usb port on the phone itself is a bit unreliable. I haven't investigated too deeply, but it took a while to find a position for the wire to maintain a stable connection. I suspect this may be why the device was bricked in the first place (disconnect when flashing rom/kernel/etc.)
Anyways, for some reason flashing the stock recovery to the phone was just not working. The guy on reddit recommended trying TWRP, and that worked immediately. However, at that point, I had no idea what the history of the phone was or what OS was on it before, what firmware it had. I tried installing the official CM13 and then Sultan's CM13 with no luck. What *did* work was Oxygen OS 2.2.6.
At this point I'm stuck yet again though... The Marshmallow OTA (3.1.3) in the OS shows as available for download, but when I try to install the download only gets to 22% and then stops. Flashing the 3.1.3 OTA.zip available on OnePlus' support site doesn't work in TWRP, and when I try to flash stock recovery, it doesn't work.. don't know what else to try.

Root your device using twrp or kingoroot method then install flashify and try to flash stock recovery using flashify. .. Tht may work.
Flashing 3.1.3 via official twrp ll not work... Cos ur bootloader version, U can do it only with stock recovery or u need to edit meta data file. Or u can flash stock recovery img file by twrp

Hi OP, sorry for joining late to the party
So the thing is the OnePlus X is at opposites now since the official MM release on 29th September. The thing is if you are running the old bootloader (OxygenOS 2.x.x) or any ROM based on it, then the New TWRP will not boot, neither will the Stock Recovery that is hosted on the OnePlus download section for the X, which is where i assume you download the stock recovery from, right ? Also note that the official recovery hosted on the TWRP website is also yet to be updated, we're working on that.
So you are on the old Bootloader. Simple stuff. I have posted my guide a lot of time around the forums, its gained a lot of merit. You could follow it for your update process. I'll leave a link below. In case you wanna verify that the old bootloader is causing the issue my Index Thread pinned in the general section has a link for the Stock recovery for Old bootloader, try flashing that via fastboot, if it successfully boots then you're set.
Comprehensive guide to Update to Marshmallow Bootloader
The above guide is centered to the thread i have posted it on but the process is 99% the same. In the end, you could just stay with Oxygen OS 3.1.3, or flash any custom ROM based on the new Bootloader.
Now regarding your query about editing the META of the ROM, well Yes to an extent it IS risky if you ain't careful because my guide guides you to delete the one single line that removes the device check, so as long as you use the modified zip on OnePlus X only, there will be no issues.

First off, im pretty new to samsung phones. i got a N950F which i installed TWRP on today since i heard it was a helpful thing if you wanted to root, and since i just came from a jailbroken iphone i thought why not. i followed all the guides and made a backup before i did wipe, but now im stuck on the boot screen. i have tried re-installing the firmware but it just says "SW REV. CHECK FAIL. DEVICE: 2. Binary: 1." and fails. any links or videos woul be helpful since i dont want to pay money if i can fix it myself. im using Odin3 v3.13.1 with the firmware file called "N950FXXU1AQI1_N950FOXM1AQHF_BTU_7.1.1_FULL" i can enter download mode and twrp but it can not boot, it reaches the samsung logo and then restarts every 3 seconds. Please help!

Need help to restore Moto g turbo edition to stock.

Okay so I am not completely noob on Android but man Motorola is hard cake.
I have Moto g turbo edition running lineage os 14. Which is consuming battery like crazy and I wanted to go back to stock rom mm.
Now as any guy would do I downloaded stock file for my device from XDA and tried following the fastboot instructions which gives preflash validation error. So on skipping the got.bin didn't help and almost all command came with same error. I tried RSD tool and all in one Moto tool with no success whatsoever.
And now phone is acting weird like it starts on bootloader and have to press Start button for it to start(but it is starting and working though).
The phone is only in India and Mexico maybe so it's hard to find device specific instructions. Though what I've found that the flashing guide asks to wipe data with stock recovery! I didn't get that. So for following instructions do I need to first get stock recovery and than wipe everything ? I didn't tried it because than I'll get into deep trouble of nandroid backup restoration if everything goes to sh*t. Please help I'll provide any help needed .thank you very much

Looking for custom rom for Ulefone Armor X Oreo 8.1

I am looking for a custom rom, minus the Google stuff, that will work on my Ulefone Armor X Oreo 8.1. I have a working TWRP recovery and have rooted it via Magisk but went back to stock after a few nagging problems.
The phone spec isn't wonderful so need something lighter but still having plenty of functionality.
Cheers

This specific device and Chipset is fairly new and there's very little on the forum that's specific to your device.
With that stated...
You have a Mediatek MT6739 (64 Bit) device that can be very helpful in that aspect.
Though I had located a few threads that won't be very helpful for you but, the following thread is about the best that your possibly going to find for your device at this point in time.
https://forum.xda-developers.com/showthread.php?t=2701283
It does take some time for developments to pop up on the forum for newer Mediatek Chipsets but, where there's a developer (with the same Chipset device), there's always a way depending on the level of difficulty.
I wish you the best of luck with your search!

I'm also looking for that. But if I can get TWRP on it I'd probably try SU.
How did you get to install the TWRP? I found a few posts but was apprehensive about whether I can use SPFT to flash original stock ROM if things go wrong. I suppose that would be the easiest way.
For what I paid for the phone, it's a decent enough device.
Using SD card as internal memory always result in the total capacity being reported wrongly..256GB becomes 512GB with 50% occupied, 200GB becomes 256GB with 64GB occupied. Still waiting for their tech support to reply but unlikely they would.
Cheers!
I have rooted it several times and flashed the stock image several times too without a problem. Haven't used SU though I used Magisk.

I do not have your issue with storage but my wireless charging mat today stopped charging but still lights up. Phone will still charge via cable. Trying to get a replacement mat.
I installed using SP flash tools on windows and Linux just to see the difference.
If you do a Google for Install TWRP ulefone armor x then you will get some information and relevant files.
Unlocking the bootloader via ADB is straightforward on Windows and Linux too. And then relocking it.

Anyone had this in recovery mode?
Had also tried flashing the TWRP but it just didn't stick and was asking for a password on first launch.
Edit.. all links I tried point to the same location to download. Same files.

im also facing the same issue... kindly someone help.. ive explained my issue below:
Can someone confirm? My device is encrypted by default, so whenever i install TWRP it says to decrypt device. I tried the pattern, changed it to password, and pin still my device doesnt decrypt in twrp. I feel its a twrp bug, because when i set the device to ask pattern during boot, the same pattern/pin/password is accepted, but not in twrp.
I want to know 3 things:
1. Are your devices encrypted by default (i dont remember encrypting my device, I dont know how it is encrypted)
2. Are you facing this same issue of entering password when you reboot into recovery?
3. What is the purpose of the boot.img in the twrp zip? am i required to flash it before flashing the recovery, or does it remove encryption?

In the folder containing the TWRP recovery there are 3 files, boot.img, scatter, and recovery. You only flash recovery, you have flashed the boot image, ensure the checkbox is unticked after loading from scatter in SP tools. That is what I think you have done to get that result.
Follow the guide here. I did it a few times before success as I followed a guide from another site.

You ignore the password and change the language to English from Russian. Just don't enter a password at all. The recovery won't stick as Android replaces it when you reboot. After you've completed other steps maybe OEM unlocking then it stays, or so I read somewhere.

All of them are encrypted by default now. The password in TWRP should be ignored and just change the language and select storage etc.

Yes all are encrypted.
Yes I get the same request for password which I ignored and selected language and carried on.
I do not know why boot.img is included it just gets in the way.
After installing TWRP unlocking OEM bootloader and all the rest including rooting it I decided it would be better to wait for a new ROM. All we need is a working TWRP and an unlocked bootloader to flash a new ROM and we have that. It doesn't work very smoothly and I felt it could be better which is why I went back to stock.
When I posted this request I didn't imagine others would try installing Magisk etc, waste of time really as you won't stay with it either. Best wait for a ROM I think.

Im also unlocked and flashed twrp. I ignored the encryption message and proceeded, hit the storage sizes show 0, and neither can i access the storage to flash anything nor can i take backups. can you go to settings>security in your device, and tell me if your encryption says enabled? Tia

Mine is the same encryption is enabled. I select external SD storage and I am shown the contents using the same procedure as yourself, I cannot tell you why this is so. I am using the same technique, same phone, same settings, same TWRP, maybe we have different SD card?
That is all I can think of by way of an explanation. It works perfectly for me. I also made a backup which I can select and restore without a problem.
