Bricked Cubot X15... seeking fix (?) - Upgrading, Modifying and Unlocking

Hi all,
I bought a Cubot X15 as a gift for my wife. She used it for a few days without a SIM card (just WiFi) and when we put a SIM card on it the phone thought it was stolen (?) and asked for a pin code we never set up.
I googled around and seemed to me that the only way to unlock it was to flash a new ROM, so I downloaded a ROM I thought it was correct, flashed it following the instructions and the phone seems dead.
The only glimpse of life is when a cable is when the laptop is connected to the phone and I press "down" and "power", the laptop makes the noise that USB is connected and then, around 5 seconds later, sound of USB disconnection... other than that NOTHING.
No other combination of "up", "down" and "power" does anything, no Chinese characters, no noise, no screen... absolutely nothing. And I am 100% sure the battery is almost full.
I would like:
1) Confirmation (as best as you can, with the information given) if I need to get a new phone or
2) Help to resuscitate the Cubot... in fact, I would prefer if I can ship the phone to somewhere in Australia and someone fix it for me (willing to pay if successful).
Thanks in advance

i need answer too, i have the exactly same problem... :crying:

[Q] Samsung i8150 problem

Hi guys!
I've been RO this section for several months, voted for its creation, but today i've finally got this epic device!
I tested it with *#0*# tests at the customer (ukrainian e-shop), took it home..
there i've switched it on, caught my home wi-fi, installed skype, firefox, got my google profile etc. Everything went great and amazed me (especially after my old QVGA Nokia N85), i even got smth like 3800 antutu score on xxla2 stock rom
then i decided to insert a SIM card in it, switched it off normally, inserted SIM and tried to switch on.. but upon pushing Power button i've got nothing .. any vibro, sound or smth on screen!
i've pulled the card out, but nothing has changed!
First of all i've tried to charge it for an hour, but no reaction..
So now i don't know what to do with this $370 piece of plastic (except than going to the service tomorrow...) i haven't even rooted it, so there will be ok i think
Maybe anyone here is able to advice something helpful? Thanks in advance
P.S. My SIM card is OK, works in some other devices, like my bro's Ace
P.P.S. Maybe my English is not so well, sry, i'm tryin' my best
You are charging with the wall charger or with the microusb cable? I had a problem with mine that look like your problem.
After a night charging my galaxy appears to be dead, I try pressing power, power+home, power+home+vol up and nothing happens.
I took the battery out, put again try turn on and no sign.
After an hour I start to role out the possible errors and I find that I pluged the fone on my microusb cable wich is disconnected from my PC, so I used the wall charger and fully charged the phone, no problems so far besides my stupity
used a normal wall charger, either it's stock one or my bro's one, both of them charge his Ace normally...
it's 8th of march, in Soviet Ukraine it's everything closed due to holiday, so i have to look at thus dumb plastic until Monday
I'm a noob so sorry if I can't answer your problem.
But as far as I remember, it's either I immediately put my SIM card before turning the freshly bought phone on or I didn't use anything important like Wifi and such...just tried to see the applications drawer and was like :O.
Maybe it's somewhat connected to what you did before you insert your SIM card..
ok, i used it a little bit but i think it's hardware problem.. i've seen and unbricked tens of phones like nokia and symbian-based samsungs, so i think i can determine, whether it's hardware or software problem
You can use your phone without SIM, I did, until I bought SIM unlock code!!!! No probs with WiFi....or Apps....just no Network..
so that is not the problem here!!!
Did you backup your apps??
In settings/privacy....
were backup data and auto restore checked?? Not sure if they are by default....but this would have backed up Apps and data to Google servers!!!
I would do a factory reset in recovery.....
you have default Stock Samsung Recovery on your Phone....
Use [Power] [Vol+] and [Home]...
3-button combo.....until you see the phone switching on......release power button then.....
release both the Home and Vol+ buttons when you see image of Android man with box.....
then tap menu button [left button]
you should be in Samsung Recovery....and there is an option for factory reset there....
Hope this helps!!!

i've tried a three-key combo, nothing happened.. phone reacts on nothing - just like it had no battery in it.. charged for 4-5 hours, charger is ok, battery is ok (around 4v output ) but the body itself is dead.. any symbols of life...
It sounds to me like problem with the SIM card slot. Try to look into that slot with small mirror if some contacts fell apart or badly bended, but anyway this is for service. It happens :-(
don't see any problems with SIM slot, looks as usual.. microSD slot is even still virgin, my Nokia N85 likes 32gb class 10 card, that was bought for SGW
waiting for tomorrow for service to open and will carry the phone there... i was amazed that service in 2 kms from my home is listed on sammy's website
So sorry man....if u can't get recovery or download.....u have to return it!!!!!
Better luck next time!!

[Q] Please help - real noob!

So my One X got stolen for the second time now (yeah, lucky me) and this time I wanted to buy it used. Well I got one very cheap, but it seems to have a software defect of some sort.
I charged it briefly and it actually seemed to work. The red light was on and so I left it for another two hours to charge some more. Unfortunately this did not help (would have been too easy). The guy I bought it from showed me, that when he plugged it after a minute or so, the led would blink red for a few times. This does not happen every time however. I tried the hard reset with no response. I tried to restart it by holding down the top button with no response. Only once it was vibrating like when it is booting, but the screen stayed black and the button row was blinking shortly.
When I connected it to the PC it was able to install the HTC Android Phone USB Device but showed that there was no driver found for APX. I have never seen that one before.
I've tried to find some answers on this board, but I don't understand jack I don't want to learn all there is about smartphones, I don't root them, I don't install anything that doesn't come from the market. Usually. As I said, I am a total noob, so please use noob-language
PS: The seller couldn't tell me anything about the mobile. He said he would sell it for a friend. I fear it's stolen, but that's tomorrows problem since I can't see the IMEI w/o getting the phone to work
The original sim tray has the IMEI on it.
Are you saying that the device is reported as APX in device manager? Then it's back to the retailer or HTC, it's not recoverable.
Thanks a lot for the tip with the IMEI. I went to the police station today and checked it out, luckily it's not stolen
About the software: The PC does recognize the phone as HTC Android Phone USB device, however it also finds another new hardware called APX for which it can't find any software. So does that really mean it can't be fixed at home?
And if that's so would I have to pay if I send it in (I do not have a receipt) or does HTC know whether I have warranty (which should be obvious since this mobile is new on the market).
- Turn off your phone by holding the power button.
- Hold the Volume-Down button and turn on your phone (while keeping the Vol-Down pressed).
- Do you get to hboot?

No, I've tried that before, it didn't work. I did send it in yesterday. They said I should get it back in 10 days time. I hope this is covered and I don't have to pay for it.
Thanks for you help!

Good luck mate! Hopefully you won't have to pay anything
So I did get it back, but it won't recognize my SIM card. HTC told me to send it in again and I am really pissed. I don't want that. It seems to work just fine, it just won't accept the SIM. It asks for the PIN code but then it says my SIM is not right for this network (which is any network I am trying). Any solution for this?
Phone sounds goosed. Get your money back
Any news?

Nexus 5x shut off and won't turn on

If I posted this in the incorrect place or there is something related to my issue, I apologize in advance.
I've been searching here and all over the internet and no progress yet so I decided to make a new account here just to see if anyone can help me because I'm out of ideas right now.
This morning my Nexus 5x (Non-rooted Nougat) woke me up like every morning, after dismissing the alarm I left it on my bed and when I came back to grab it later I noticed it shut off.
Here are the facts and what I have tried so far:
- Battery level was almost full
- I tried to turn it on but nothing happened, not even the Google logo
- Connected it to power and no icons or any response at all
- Left it connected for like an hour and tried to get it into recovery mode
- I was able to get into fastboot mode a few times but after electing "start" or "recovery mode" the Google logo comes up and then shuts off again right after.
- Tried getting into recovery mode after leaving it charging for a while again but I couldn't even get into fastboot this time, no signs of life at all.
- Disconnected the battery for a few minutes and tried to get into fastboot mode again, this time it worked but same thing happened. (Google logo then shuts off)
- Tried connecting it to my PC but doesn't show up on Linux nor Windows, on Windows it makes the sound like I connected a peripheral but that's pretty much it.
- I have USB debugging enable but never accessed my stuff through usb connection because I have had this issue before where it is connected but it won't show up or it shows up but won't let me access the files even though the phone is unlocked.
At this point it just won't do anything and I ran out of ideas. I just want to at least recover some pictures and information I have in it that isn't backed up, if anyone can help me I would greatly appreciate it.
Thanks in advance
It sounds like you might have encountered the hardware bootloop issue. This is theorized to be caused by bad solder for the eMMC chip or bad eMMC chip. This was an acknowledge problem on a related model LG phone, but hasn't been acknowledged for N5x.
If you are under warranty, you should start the replacement process before it runs out.
If you want to try something that sounds crazy but has worked for some people, put the phone in the freezer for 15 minutes then see if it boots. If it does, quickly back up as much data as you can, then wipe the phone in preparation to RMA exchange.
Just boot to bootloader (fastboot) then unlock it and flash a factory image... u can find many guides to this operation on the XDA

If it's a hardware issue like sfhub suggested, I don't think this will fix it.

Same here... cannot enter recovery mode, so flashed new rom stock rom.
The flashing was fine but it didn't help.
guys if u can get to the bootloader, sure it can be fixed.. everything is possible with the fastboot, u can fix any issue. if it's a hardware issue the bootloader wouldn't work as well.

I've had the same problem with my 5X, except my alarm didn't even go off! I woke up 15 minutes late to see the boot screen "enter your pattern to start Android". I entered my pattern and it looked like it was going to boot up but when I went back to it it was blank. Tried again, got to the Google loading dots and it switched off again and I haven't been able to power it up since. No bootloader, nothing. Tried all the troubleshooting steps on the Nexus Google Support pages (I did post a link but because I'm new it won't show, so just Google "Nexus Support") and nothing worked. I also knew the battery was fully charged because it had been on charge overnight and when I did get to the 'enter your pattern' screen, the battery icon in the notification bar was full.
I requested a call back from Google and nothing happened so I tried the chat and they said it sounded like a hardware issue and are sending me a replacement device within the next 3-5 working days. Good that they're replacing it. Bad that it happened on a device less than a year old and they only offered £10 Play Store credit by way of compensation, when I've had to spend £15+ on a PAYG sim card to use in my old phone in the meantime because the nano sim in my 5X was too small and I've spent over an hour and half this afternoon wasting my time with troubleshooting and waiting for a call back... Not really the customer service I expected from Google for what appears to be a hardware issue. If you bought the phone from Google, my advice would be to get in touch with Google Support and they should replace it under warranty.

I contacted Google and they didn't help me at all because my warranty expired last month, they literally just told me to put in a repair request at the LG repair webpage....this sucks
My experience exactly...
My wife's Nexus 5 exhibited the exact same symptoms this morning. It's been running perfectly for 20 months and today it died, and we're unable to even get into the bootloader screen or power on the phone.
Taking your advice, we put it in the freezer for 15 minutes and were able to perform a factory reset wiping all data from the phone. We are going to take advantage of Google's Christmas 2017 promotion and return the Nexus 5X and buy a Moto 4X. They require you perform a factory reset before returning the phone in order to receive a credit for the returned Nexus 5. Thank you so much for the help!

I've just posted this thread overlooking yours. I think this is becoming another common issue. Has the freezer trick worked with anybody else?
I am having the same issue described here. My Nexus 5x went into a Bootloop about one month ago, but I was able to get it working again by going into Recovery Mode. About 4 days ago it went into a constant Bootloop, just showing the Google screen, and I couldnt get back in to recovery mode. I ordered a new phone on Tuesday (Pixel 2) and as long as I am able to do a factory reset I should get a $150 credit when I send this phone back. So, in desperation, I took a chance on the 15 minute freezer trick, and it worked! I was able to get into recovery mode (power + volume down, select Recovery Mode, little dude on his back came up, pushed power + volume up once) and cleared the cache and applied the factory reset. Ridiculous that this phone only lasted 18 months, but if I get the $150 credit I will be happy.
Same problem here -- just froze for a few seconds, powered off, and won't turn back on. Not a boot loop issue as there is no response at all from any buttons. Swapping the mainboard from a working phone powered up without a problem, but obviously that's the other phone's emmc.
I tried the freezer thing and it sort of worked- LCD powered on for a couple seconds, but then shut back off again and even that only happened once. That's progress over the usual absolutely no response though... Anyone have insight into why the temperature would matter? something is overheating that this gives a bit of wiggle room since it starts much colder than usual? maybe a more complex analog electronic situation?
I would happily pull the flash chip off and put it in a emmc reader, but I think I'm out of luck because from what I've read the dm-crypt key is generated from some data stored in in the processor's trust zone thing. I know the "password" but if that's only part of what makes the key and the rest isn't on the flash chip I suppose there's no point in going that route.
I don't care about the hardware surviving; mostly just looking to recover my data. Anyone have suggestions? Hardware debugging direction? I'm willing to buy some electronics test equipment (within reason of course; not picking up a 10000USD rework station for some old photos and contact list...)

The only way to connect that buddy to PC is to get SoC (CPU) working, so theoretically you can go towards reballing the chip. But I guess it's not an easy thing for such a little chip. Also u will need kinda plate for balls, i think there are no common ones, so u can make it yourself if have a technical education.
Another way is to connect memory right to PC without a phone but with some connector. IDK if there are any available, but this looks much more simple. I actually got the same happened, and tried to heat the plate, but with particular success.
IMHO

Here's the reader
https://www.amazon.com/ALLSOCKET-eMMC169-Programmer-Kingston-Interface/dp/B06Y55DKND/
But I assume the problem is I will not be able to generate the encryption key because part of it is in the processor.
If someone has tried this and it definitely works, I'll give it a go. Just don't want to buy the emmc reader and heat gun this chip off if it's certainly a waste of time.

Hard Brick on LS991

Hi
The other day I was looking for cell ID info on my LG G4 that I have had for a long time in the "hidden menus". I accidentally clicked on the radio test and the screen froze up. I tried to get out of it, but noting would work, not even the power button. After a few minutes, I saw the power off sequence. When I went to turn if back on, it would not power on. I plugged it in, no charge. I tried to boot to recover, nothing. I have the service manual for the h815 variant which differs from mine. I do not have a boardview or anything.
I know trying to permanently fix it is a lost cause, it is old and it had other problems, such as the headphone jack not working even after I replaced it, and the read camera's autofocus being stuck after I replaced it with a cheap knockoff. However, I want to get it running long enough to get important things off of it. I was foolish and a few of my 2FAs are only on that device, and while I have gotten most of them switched to my alternate, I need to make sure to get the rest. I'm not sure which troubleshooting route to follow: Power? Crash/No Boot? No charge? I would follow each but some of the differences between the board I have and the service manual includes a few of the test points I need. Currently I have to attach wires to my multimeter leads to get small enough tips.
If anyone has anything that can help me get this running for a bit, let me know please.\
edit: biggest problem is I don't know how to tell from the schematic what pin is which on the board

Sounds like the ilapo but as you have modified the hardware it can be everything of course . anyways it wouldn't hurt to try some of the Bootloop fixes which you can find in my signature . Your best chance might be flashing the TWRP version for the ilapo and trying to load the recovery. Another option is of course to get into download mode and use salt to backup the user data partition.

S20 Ultra Bricked (G9880)

Hi guys, i come here searching for help, it was a normal day, i was out with the phone fully working, it was on my pocket, when i get home i see that it's off, tried to turn on and nothing... tried vol- and power to enter download mode and nothing, the screen is always black.
Connected it to my laptop to see if it shows up as a USB device, it sounds like it connected and in "Device Manager" it show as "QUSB_BULK_CID:0412_SN:BA92F870" but ODIN doesn't detect it, so i can't try to install a clean ROM.
I can't take it to samsung as this model is a HONG KONG one and i'm in Chile, they won't apply warranty and legally i had only 3 month in a external shop but i'm on my 5th month, so it's not use to try that way.
A few points about the phone:
Latest firmware: (INSTALLED NATURALLY, I GOT IT FROM SAMSUNG OFFICIALY)
Country/Carrier: Hong Kong
Date: 2020-10-26
Version: 10
PDA: G9880ZHU2BTJ6
CSC :G9880OZS2BTJ6
NEVER EVER tried to install a rom or something on the phone, i was happy with how it works and the battery i got from it.
Now i bought a S20 FE as a momentary replacement because i can't be without a phone for my work... i've read lots and lots of threads on XDA and other places but all of them are about the Note 4, so it's really out of date to try fix it that way, at least 6-8 years old posts.
Anyone here had a similar issue? is it fixable?
Hope someone can help, it really hurts loosing a phone that costs +USD1000
Thanks guys.

NEVER EVER tried to install a rom or something on the phone, i was happy with how it works and the battery i got from it.
Now i bought a S20 FE as a momentary replacement because i can't be without a phone for my work... i've read lots and lots of threads on XDA and other places but all of them are about the Note 4, so it's really out of date to try fix it that way, at least 6-8 years old posts.
Anyone here had a similar issue? is it fixable?
Hope someone can help, it really hurts loosing a phone that costs +USD1000
Thanks guys.

Hi guys, i come here searching for help, it was a normal day, i was out with the phone fully working, it was on my pocket, when i get home i see that it's off, tried to turn on and nothing... tried vol- and power to enter download mode and nothing, the screen is always black.
Connected it to my laptop to see if it shows up as a USB device, it sounds like it connected and in "Device Manager" it show as "QUSB_BULK_CID:0412_SN:BA92F870" but ODIN doesn't detect it, so i can't try to install a clean ROM.
I can't take it to samsung as this model is a HONG KONG one and i'm in Chile, they won't apply warranty and legally i had only 3 month in a external shop but i'm on my 5th month, so it's not use to try that way.
A few points about the phone:
Latest firmware: (INSTALLED NATURALLY, I GOT IT FROM SAMSUNG OFFICIALY)

The device is powering on and off randomly on it's own, correct? This sounds like a hardware issue, you may have a defect somewhere in the power supply chain. If you have a reputable repair agency nearby, not necessarily Samsung, this would be my first step. Not sure why Odin isn't detecting the device. Here's an article which offers common solutions for this problem.

Yes, but it doesn't work, screen alway stays on black, i know it's not fully dead because it sounds as a USB driver when connected to my laptop

tomorrow i'll try to take it somewhere, thanks for the link, but i already tried all those tips
I take it you have a Qualcomm cpu? If so you need to install the Qualcomm usb driver, link https://gsmusbdrivers.com/download/android-qualcomm-usb-driver/ or a newer version if available. This should solve the problem in regard of pc connection, usb recognition and most of all reading the internal memory. Please use Google search for mor info and the correct procedure as i never used this myself. Good luck.

Anything you can find on google i already tried, installing the drivers didn't help either... thanks tho!
Oh hey, its you! We spoke on reddit a few days ago about this problem, sorry to see you haven't been able to fix it.
Have you tried all your USB ports? Or maybe another computer? Worst case scenario there's a solid chance Samsung will repair it either for free if you're lucky or for a price. Even if you bought it from another country there's a possibility the manufacturer's warrant is intact especially because it sounds like you didn't do anything to the phone at all that would've warranted the sudden failure.
Does ADB see it when it's plugged in? If you don't have ADB installed follow this: https://www.xda-developers.com/install-adb-windows-macos-linux, then once installed run "adb devices" from command prompt.
