HELP! Asus Zenfone Max(8939) - Asus Zenfone Max Questions & Answers

So I have an Asus Zenfone Max(ZC550KL) which is more or less unusable at the moment. I had been using it for a year and 4 months now and it worked like charm. But for the last few weeks, It had gotten incredibly slow. So day before yesterday, when I got some free time on my hand, I decided to flash it with a custom ROM.
Basically I checked xda for some good ROMS and decided which ones to flash. Also had to unlock the bootloader which I did using the app from the official Asus website. Also managed to get twrp recovery and root it. I somehow managed to flash a custom ROM but it wasn't working like I expected(No wifi or network) and so many other things. So I decide to flash the stock ROM back and this is where I screwed up in probably more ways than one.
So I went on to search as to how I could go about flashing the stock ROM and one of the instructions said it was as simple as using the firmware from the Asus website and installing the zip through twrp. At the moment I wasn't aware that the 16GB and 32GB were actually different variants, one which had Snapdragon 4XX and the other had 620 processor. The website initially listed only 8916 firmware. I didn't think a whole lot about it and used twrp to flash it. Since then the phone isn't booting up, can't get it into the CSC mode or recovery mode. Later on I managed to search a Asus website a little more extensively and somehow managed to find the 8939 as well. But without being able to boot into the bootloader mode or recovery, I don't know how to go about it.
I am not getting the charging symbol either, and whenever I plug into the PC, nothing is recognized. But from time to time, if I press the power button long enough, My PC says an unrecognized device is plugged. Is their anything I can do to to revive the phone or should I lose hope at this point? Also I understand changing the motherboard could fix it, but is the price worth it or would I be better off buying a new phone? Any help would be highly appreciated.

What is the device model exactly , the 8916 or 8939 CPU ? How exactly is the device showing up when you connect to pc, showing up as a number of local drives or what ?

Not showing up at all. sometime back, if I pressed the power button long enough, My pc would tell me there is some unrecognized device connected. Now that isn't happening either. Its the 32 GB Variant with Snapdragon 625, So 8939. But I flashed the phone through twrp, that too with 8916 firmware.

ZTE Obsidian Z820 Questions

Looking around on the web for days and I'm finding absolutely nothing online for custom or official firmware downloads. I only bought this phone due to budget constraints and a week or so ago ZTE pushed out an update which errored during installation causing my phone to be stuck in a perpetual bootloop. Does anyone know of anything out there that can help me get it fixed so I don't have to waste more money on a very limited budget? Searched through and found a few various posts about rooting (which is easy, just use kingroot app and done) but I need to actually reinstall android fully and ZTE themselves just basically told me to go **** myself by sending me a link to buy another.
hi friend do you find a official firmware?
i have the same issue and i cant find nothing

Need help with Asus Zenfone 6

This is my first post on XDA and i am in desperate need of help. I own a Asus Zenfone 6. Recently i tried unlocking bootloader and installing TWRP recovery so that i can flash a custom ROM. It went horribly wrong and i bricked my device. I managed to unbrick it and revert to Stock ROM which i also upgraded to LOLIPOP using adb sideload. I also managed to root it and have super user access. The problem is that i cannot install a TWRP or any other recovery. When i try to install a custom recovery i get and error " cannot install unsigned image on secure device" which probably suggests that the boot loader is locked. I ran the commands to unlock the boot loader and they ran successfully but i am not sure if the bootloader is locked or unlocked.
I tried running fastboot oem devices but i get an error " Unknown Oem command".
It was after hours of troubleshooting that i decided that i am OK with stock LOLIPOP rom as long as i have a rooted device. It was after sometime that i noticed that the camera wasn't working. Also the flashlight wasn't working. I uninstalled the updates and flashlight was working. However the camera just gives me a black screen for some time after which it quits with an error message " Camera is used by another application. Please reboot your device and try again". I uninstalled the updates for Camera and reverted to a previous version by also removing the camera application using super user access. However for an older version i get an error " Camera not found". I have also tried installing other camera applications but none seem to work even after making them a part of system. Currently flashlight works but only under an older version , as soon as i update it stops working. I decided to lock the boot loader again as it was just not worth it. However after running the commands and locking the bootloader i still cannot get the camera to work. I tried in safe mode and the camera won't work there either.
When i go to recovery i just have four options, there is no install from internal storage or SD card which suggests i am on stock recovery.
Currently i just want my camera to work. I am OK with the stock ROM and recovery as long as i have a rooted device. I have spent hours researching and nothing seems to work. I am in desperate need of help. Some of the friends suggested to try my luck here. I would be indebted as i dont want to purchase another device just because i screwed my camera. Also when i was under kitkat i ran the SIMI test and was getting an error 1667 and 1668 for both cameras. The test is failing under LOLIPOP as well. I dont think its a hardware issue or maybe i am wrong. Any help would be appreciated.
Thanks.
Not even a single reply. DISAPPOINTED!
You need to Lock Bootloader then reflash the rom (wipe all) to fix it. Custom ROMs sometimes cause camera not working cuz there are some devices that have different camera.... Next time, just make sure you Lock Bootloader => Flash Stock recovery => Wipe => Flash Stock ROM

NOT EVEN A REPLY BACK
But yeah that sounds like a roller coaster.
Just picked up the Zenfone 6 to see what I could do with it, I'm going to try to flash the RR rom on here.
Just something I noticed though, I did some research myself, and a couple of sites like this one (https://zenfones.gajetzki.com/) say that you should root your original stock before doing anything. Now this wasn't a requirement at all in my experience for all other phones so I'm a bit skeptical. Anyway I thought that may help in some way.
Good luck!

Sorry for the late reply, but I'll try to help as much as I can. First things first, I know there are two different models of the Zenfone 6, the A600CG and the A601CG, but apparently this shouldn't make a difference, but it could have in this case, after all they must have different names for a reason. Also, the support for the Zenfone 6 is pretty terrible in terms of custom roms and the such, so you may even be better off with the stock experience, just root it and you'll have all the functionality you could ever dream of.
If you're still keen for the custom roms and stuff maybe check out this thread:
https://forum.xda-developers.com/zenfone-5/general/recovery-twrp-2-8-6-0-asus-zenfone-5-t3136263
Other than that, I guess Google is your friend, but so are we!
I haven't been able to hold onto my Zenfone 6, as it was a friends, so I no longer have it and never got the opportunity to have some fun with it, so I'm just going off my own experience with my HTC One M9, which is probably vastly different, but I suppose the process isn't too different. Nonetheless, I hope all goes well!

Custom ROM for Redmi Note 3 SD

Hi folks, long time reader, first few times posting however.
The short story:
Redmi Note 3 SD 625 password system corrupted, unable to access it.
Used Miko Tools to remove the lock function. Got access to phone.
The unlock process left me with MIUI 8 6.9.9 on the phone, and the Wifi and BT are both stone cold dead.
I cannot seem to unlock the phone, it's being stubborn about that, however I can get the phone into EDL mode. I have put the phone into Dev mode, and enabled USB debugging.
My only choice to fix this dead Wifi issue, seems to be to flash a new ROM on it, but all these ROMS confuse the heck out of me, I dont know what to use. All this stuff, I have had to learn by reading, and it is on the absolute edge of my computer/tech limits of understanding.
Could someone please do an old guy a favour, and just suggest a stable, dependable, non flashy ROM, that has working Wifi on it, and let me know if I can flash the ROM using MiFlash in EDL mode.
Thanks a lot people. You saved my personal phone last year, lets see if you can rescue my sons one this time.

Just Flash MIUI 9 stable via edl it solves everything
Thank you Sampath, I appreciate your help.
Still having no success. I download the MIUI 9, but is that a file I can flash via EDL mode, or just update using the phone only?. I keep getting a message saying unable to find flash script. The phone is in EDL, and shows as the right Qualcomm 9008 thing in the Devive manager, but if I am not getting the "less than zero" error, I get the flash script one instead.
http://en.miui.com/a-234.html
Search your phone in the list of this web.
★ Redmi Note 3 SD Latest Global Stable Version Fastboot File Download
★ Redmi Note 3 SD Lastest Global Developer Version Fastboot File Download
★ Redmi Note 3 Special Edition Latest Global Stable Version Fastboot File Download
★ Redmi Note 3 Special Edition Lastest Global Developer Version Fastboot File Download
you need to extract the files.
Got the rom, extracted the files, but now Im getting
length cannot be less ythan zero parameter length
I wish these things could be simpler.
Everything Ive read for the last 4 days of trying to fix this phone says I am at the point where I simply open MiFlash, it will then see my phone, which is showing as the correct Qualcomm 9008 device in the coms section of device manager.
Surely this is just a crappy driver or something that I have missed, I have the right rom (fastboot), and the absolute latest MiFlash, the red light is blinking on the phone showing it's in EDL mode, but im stuck with Miflash not being able to see the damn phone, and giving me this less than zero message over and over.
Well, this story ended up with me giving up. Going to stick with the big brands from now on. Thought I was getting something good with these redmi phones.

I found Miko as a link on a youtube video. All other screen unlock methods I tried failed. Miko worked first time, and had other features on it too. It covers a lot of mainstream brands of phone by the looks of it.
As an update, after my rage quit earlier this morning, I found a program that lists all your USB ports? drivers? installed (not really that computer literate sorry), and it showed me a heap of residual drivers left over from my Redmi note 3 MTK flash that I did on my phone earlier last year. I uninstalled dozens of dead or unused and unrecognised usb devices and drivers using this program, and then unintalled anything Xiaomi or Redmi on the list, and started again.
I plugged the phone in, it went to install the drivers, but I specified which ones I wanted to use, I opened MiFlash, and it recognised the phone instantly. I flashed the phone first time, no issues.
If anyone else is stumbling blindly through this process, I all I can say is DRIVERS, DRIVERS, DRIVERS !!!!!. They are the key to your flash working, in my opinion.
The 2 programs I used are linked below. I needed Miko because the the reason for the flash in the first place, was because of a corrupted password system in the phone, that locked us out of it completely. Miko solved that in seconds. The second program is USB-deview, and that showed me all the USB issues and old and incorrect drivers I needed to get rid of. I hope these help someone else out of a jam one day.
These two files are hosted on my personal FTP, they will be clean and virus free.

I mentioed in my earlier posts that I flashed my MTK last year, but that I was working on my sons Snapdragon this time.
I have 3 Redmi phones now.
Mine is the MTK, which I flashed last year.
My son has the SD version, which is the one I was trying to fix.
My wife has a Note 4, which is fine.

Why all the questions still?. I mentioned in my earlier post that i had fixed the phone now. It's running perfectly on MIUI9, and the wifi and BT are working.
If it helps........
The device showed as the correct Qualcomm 9008, but it was showing correctly the whole way through, but the heap of old MTK drivers must have been confusing the issue.
I'm on Win 7 64b
MiFlash was the latest one off the official website

For anyone having issues changing from CN to NA ROM on the 5S

There's a little story i needed to rant about before i wrote this guide so read if you'd like if not tldr; will be down below
NO ROOT OR BOOTLOADER OR ANY FORM OF CODING NEEDED FOR THIS FIX, THIS METHOD WE WILL BE USING OTG AND THE RENAMED STOCK NA 8.07 ROM FOR THE 5S GOING FROM CN 6.23
Requirements​ - NA 8.07 rom from the official redmagic website
- A Computer/laptop
- USB stick (mine was usb2.0)
- OTG adapter (if you have any old samsung phone boxes look in them there's usually one)
Hey guys! First of all im terrible with technology, i havent touched a computer in over 15 years before 4 days ago.. So i bought this phone 4 days ago as i needed a decent phone with a snapdragon soc (samsung uses trash exynos in Australia). The shop i bought it from didnt tell me it was the cn version and thought he would just have NA version as thats what it says australians will recieve on the official site.
So i did some research and found out we can easily change roms using the local update thingy so i dl'ed the 8.07 NA rom and it would load to 25% then freeze, reset and nothing would happen.
So i tried the OTG method, same thing again, 25% then crash and reset. So at this point im starting to get pissed, i downloaded the latest 5G NA rom and tried to otg method that rom to the phone. It loaded to 80%, crashed and hard bricked my phone to the point of where it was corrupt, couldnt get into recovery and couldnt factory wipe,
I was however, happy to see the boot logo had changed to english though so i didnt give up, 3 days, 3 f##ing days i was trying to research flash guides, recovery guides, root guides, downloaded about 100 usb drivers because i wasnt updating to the right drivers at the right times when plugging in and unplugging my phone, i tried unbrick tools and when trying to fastboot it was saying the password was incorrect (fastboot oem nubia_unlock NUBIA_NX659J is what worked for me to unlock fastboot. all the guides i read said the fastboot cmd was
fastboot oem nubia_unlock NUBIA NX659J) nothing worked. Luckily i had gone into dev options after reading a guide and unlocked oem unlocking and usb debugging before the phone bricked as this is what helped unbrick my phone. I had to individually flash each .img file from the CN rom back to the phone.
I didnt know how to code or do cmd thingys before i bought this phone. Now i could f## join anonymous im that good LOL but yeah i managed to unbrick, wipe, and flash the NA 8.07 rom to my CN 5S using OTG. You wanna know what i did to make it work? I can tell you right now it didnt need a f##ing 4 day crash course on hacking and coding.
TLDR; bought CN rom 5S brand new from shotty phone shop, i couldnt get the NA rom to load past 25% on the local update so i went through hell and back.
I highly highly recommend unlocking developer options in your phone, turn on oem unlocking and usb debugging before doing any updates or experiments with this phone, just incase anything goes wrong with any updates
Solution:
- Always back up your phone before anything you will need to do a factory wipe after doing this
- Change the name of the NA 8.07
NX659J-update.zip folder you downloaded to "update"
- Copy that update.zip folder to a freshly formatted fat32 USB stick, do not unzip and copy. It has to be the zipped folder then safely eject the usb from the PC
- Hold the Volume up button and the power button until the screen turns on, once the screen turns on release the power button and you should reach a blue screen with 2 language selection buttons, use the volume keys to navigate and the power button to interact.
- After choosing language you will see "choose a package" and some other buttons, this is recovery mode.
- select "choose a package" and plug in your OTG adaptor and USB stick
- Select OTG method
- Find your "update.zip" folder it should be right there
- Start update and keep an eye on the phone incase any errors pop up it should take about 5 minutes to update and it will stop at certain points (stopped at 80% for a good 30 seconds for me) for bigger files so dont stress if the numbers aren't moving. I was tapping the screen so fast with anxiety at 80% hahah
- After the update go back to recovery and wipe data/cache partition and reboot
- Enjoy your goog apps
unlocking dev options and using the oem unlock option is not necessary for our device.
Unlocking the bootloader also corrupts the fingerprint sensor data, making fingerprint break.
when you need to flash a rom and the normal method does not work, flashing though recovery normally works.
as you have a CN variant of the phone. note you cannot use the NFC function. as there is no NFC chip on CN variant devices.

Oh i didn't know that! I was unable to flash the na rom through recovery until i renamed the zip folder lol but i wish i knew i had to rename it before i bricked my phone.
Im not sure how to relock my bootloader and fix the fingerprint sensor, i read somewhere theres a number to dial #xxx# for the calibration but i cant find it

fastboot flashing lock or fastboot oem lock I think are the commands to relock your bootloader. which after a wipe should restore your fingerprint.
you can then follow my TWRP and ROOT guide on XDA here for the 5S and not have flashing problems again.

all 3 regions had the exact same hardware.
with the exception of the NFC chip on the CN units.
if you can live without NFC the phone should be the same and function correctly with any of the roms once you're able to flash them.
its just that there will be an NFC option in the rom, it just wont activate, since you dont have the actual hardware.
if you were to give the phone back look into buying it from redmagic directly. as Nubia's Warranty only covers direct sales, it does not cover any 3rd party website this includes places like Nubia store on Aliexpress. you won't get official warranty from there.
only the redmagi.gg or nubia homepage which normally directs you to redmagic.gg will support official warranty so this is something to consider.
but also, as you've unlocked the bootloader, flashed things and what not. if the seller knows or finds this out they can refuse a refund as you've modified the system.
good luck either way.

How to fix OnePlus 8 pro won't turn on

Hi everybody. I downloaded IN 2025_11_C.16 https://forum.xda-developers.com/t/oneplus-8-pro-rom-ota-oxygen-os-repo-of-oxygen-os-builds.4084315 via fastboot uploaded to my Oneplus 8 pro. After the reboot, my phone turned off and didn't turn on. I tried all kinds of inclusion methods. The phone is not responding.
Similar to that, I upgraded to C35, went fine, but then tried to fastboot boot latest twrp. Got corrupted. Tried to flash/boot stock boot. NOthing. Same with patched boot. The followed instructions to flash everything. Flashed ok. But after fastboot reboot, doesn't turn on at all... Phone is dead. Can't be recognized as usb from windows, or any sign of charging even with warp charger

You can't kill the phone that way, try making and Qualcomm Id and use the Qualcomm packager manager to get the tools needed for windows 7,8,10,11

"The followed instructions to flash everything. Flashed ok. But after fastboot reboot, doesn't turn on at all..."
He flashed everything which usually means you flash all images extracted from payload.bin and this means you flash xbl.img and xbl_config.img too. But are supposed to be flashed on 8 only (ddr4 ram) only and will kill 8pro/8t/9r (ddr5).
I wish i am wrong but if he flashed ALL via fastboot this is what happend.

Im sorry for you. Thats an expensive lesson to learn from. If you are lucky you get a free replacement depending on the rules of your country etc. Im from germany and i guess i would get a free replacement here. Anyway if not and you search for a good phone, i recently bought the onepplus nord ce 2 for around 200€ on amazon. Its a decent phone and my dad is happy with it.

Hopefully will get it here too(UK). Will see. Stupid thing is that it is almost new. Less than 6 months from new. But what's worse, is that now left without phone and signal reception for some days... The bad thing of not having any spare phone...

Yeah tbh I have every photo etc backed up. Also run my daily swiftkey backup before updating. But the big big bummer now is that I have no way to restore banking apps to tablet atm... Anyway let's hope at least they replace it...
As I understand it, the phone can be thrown away
how will Qualcomm ® Package Manager help if the computer does not see the device.

I know this topic has been brought up before. But there is not always a half and full explanation.I have Oneplus 8 pro too. I can't enter recovery mode. Boots into fastboot. I've printed a wide variety of msm tools files from edl. It writes smoothly, but when opening the boot screen, it says "your device is corrupted it cannot be trusted and may not work properly" and does not open. What could be the reason? Android 10 11 msm roms, Coloros Hydrogenos all but all tried. There is no recovery. I can't open the oem lock, I can't do anything.

Not true oh I know this because I did that as well flashing the wrong ram but I was curious when time and plugged one of my Samsung phones into it and they were able to go into file transfer mode winning the phone is running the problem is getting it picked up with the right driver setup according to know I have read on Qualcomm forms it seems like it's a set of drivers not just an individual one if the device is at the point where it doesn't get to the EDL mode. You can get the signed version of the qualcomm drivers off their website using the qualcomm package manager
