Hello, my first post here. So, i got my moms old tablet which had broken usb port. Changed the usb port, let it charge for a while and tried to start it. Loaded up the lenovo text, then went to the recovery screen. Decided to do factory wipe since i was gonna do it anyways, then started the tablet again. Got to te lenovo screen only to load for a while, then displayed this: EFILINUX ERROR [android_image_start_partition:583] ReadDisk : Time out
(Attached is a picture i took)
Now it wont even try to start. Did i mess up somehow changing the charging port or is it something else? I remember the tablet veing very slow and rebooting itself sometimes when it was in use years ago.
Edit: resoldered the charge port now starts and charges but still bricked.

Hi there,
i don´t know what to do. Since 3 days now i have only a bootlogo which disappears after 5 seconds and than my screen is just black. There is no chance to turn the device on again or to do anything with it.
Even connecting it to my pc isn´t working with a factory cable or a fastboot cable at all.
My device was rooted but i had not installed anything with my fastboot cable because i just received it 2 days ago.
What can i do now to reinstall a clean rom? Is there any idea?

What did you do to get your device in a bootloop? Also, Are you sure your fastboot cable isn't faulty, Have you tried it before?
To be honest, i don´t know?! My girlfriend just told me that the device is offline and i tried to switch it on again, but i failed every time i tried.
I assume that the cable is working, because when i plug it into the device, for a short second the fastboot logo is coming up, but then i have the black screen again.
My problem is, that i dont know what to do now at all. Can you give me any proposal?

Press lightly up or down on the micro USB connection,sometimes it is not good connection,
AW: Stuck in Bootloop without USB connection!
Try to hold on/off button for more than 30secs and look if it resets

I have this problem too. It doesn't connect to adb or load into recovery mode.
Was there any changes in the last 3 days?
Hello guys,
At first, I know that the problem of stuck boot animation is common and there are already a lot of topics about it, but here I have some particularities that create a really bigger problem.
The problem started when my Nexus 4 stopped to connect to any pc, I tried more than 5 computers, diferent drivers, 3 cables, changed my rom, tried to connect in recovery, fastboot and anything find my phone, it just charges...
Then I decided to buy this USB port replacement:
http://www.aliexpress.com/snapshot/7111654281.html?orderId=71054284143593
After the replace, the phone won't turn on anymore, stay always on the boot animation of chroma rom, I tried to wipe cache and data, restore previous backup, factory reset and reinstall the rom, put back the old USB port, nothing worked.
The possible good point is that, with the new USB port, my computer detect a device when I plug the phone in bootloader mode (this wasn't happening with the old USB port), but I can´t get in ADB mode.
Help me please guys!
Help me please guys...
Can it be a problem at the logic board?
Hello XDA, my virtual phone heros, i appreciate your good work, i am reading here for a few years as a ghost and today i signed up because i am lost with a serious problem on my Note4 N910C (English is not my native language)
THE CONDITIONS AND ENVIRONMENT:
My Phone was first running on stock Lollipop 5.1.1 when i rooted it over ODIN 3.10.6 with space X kernel and CF Autoroot, SuperSU then i flashed the latest TWRP...
After that i flashed a Custom Rom: Sweet_ROM_V17.1_COJ2_N910C...
Everything was running flawlessly for about 2 weeks...I installed Titanium Backup, Xposed, Xprivacy Pro, Busybox and a lot more and made a complete TWRP Backup then, it was running like a charme...The backup is fine because when i messed up my phone through trying harder xprivacy parameters and other tweaking i needed to set it back by TWRP into the old state...
Nothing happened after that, it was running 100% for over a week of heavy usage...
THE PROBLEM:
The one morning i took it from the charger with 100% Battery and went to work...
Before the error occured I did some searching on the internet, used chats. movies, nothing special this day, USB Debugging was On, i remembered something messed up my chrome browser like this ad hijackers, i set it back by erasing data,cache of chrome in the app menu, then there was nothing else strange i remembered, my AF Firewall was closed, only Whatsapp and Browser were allowed to going through...
The same day in the afternoon i tried to use my car charger to recharge my Note 4 as usual, but this time it wasnt recognizing the charger and my first thought was that the charger is faulty or the cable, so i turned off the phone by the androids power menu...I retried loading my battery In the phones off state but when i plug in the charger, the battery symbol came up for short and then it remained dead, it s the same scenario until today, so i used my powerbank to try charging, because the powerbank has an indicator to show the loading state and everytime i plugged it in, it came up for short, battery symbol shows up for a few seconds, but no percentage or animation is showing as usual and no red LED, then its switching off, the powerbank LED indicator stops the loading state after a few seconds, so the loading current stops...
At home i tried the stock charger and it remained the same, since that, i have to charge the battery outside the phone...
The strange thing is:
The Rom is still booting fine, TWRP is booting, but its not going into download mode from Androids Power Menu like before, its always just rebooting back into android if i choose download mode and i have to take the battery out and back in and hit the download mode pattern Vol- Home Power, to enter Download Mode and even the booting into Download mode from TWRP gives the same strange results:
On my Laptop i started the device manager to see the USB hardware string parameters after a windows popup was telling me something like "Device not recognized"
The USB Driver ID dont fit the old right driver ID, it seems to be empty and the port is not communicating anymore
since the charging bug occured,( Everything worked fine the day before.)
I tried my Laptop to narrow down the bug with the same driver i used for flashing phones (S6,910F,910C) over ODIN and my Lappy has USB 2.0 and USB 3.0 ports.
I always used the same USB 2.0 port for ODIN and other MTP stuff, but since the bug showed up the 910C is not recognized at the USB 2.0 Port anymore, seems to be dead in the devices manager table, only the USB 3.0 Port shows it as unknown device with a strange empty ID --> I tried the other devices like the N910F and G920F that are still recognized by ODIN on the same USB2.0 and 3.0 Ports both with the same USB hardware strings, its just the N910C that isnt recognized anymore, in no mode, no ADB, MTP, no download mode, everywhere the same, USB is bricked! Windows finds no driver and says its no info avaiable on this device so I tried to force the right driver to run with the wrong buggy driver ID but its not communicating, ODIN indicator and log remains unchanged...So it seems to be the same situation like other people getting from killing the bootloader by bad flashing, the only difference is that my phone is still booting fine into recovery and even Android but with no charging. My USB Port is totally useless now, its like if Samsung or Google OTA update has overwritten my bootloader or something hidden in the rom that woke up to kill my mods i dont know and now.
PS: Things i tried so far with no results on fixing my issue....
1. Complete fresh reinstall of Sweetrom, 2. Flashing another kernel...
3. Roll back to my TWRP Backup of perfect running ROM but with no USB support anymore:
The Phone remains in unknown state, not affecting ODIN to switch into flash mode
I am sure its the bootloader, since its battery bug is still occuring while the phone is in off state...
Unable to tell the charger the right ID without USB communication...
i was wondering if there is a solution to make a bootloader hotflash from out of Android or something like getting me back on stock first with download mode, forcing the USB ID or communication with a tool out of android, SD card boot image like on note 3 whatever, please tell me! I cant find something related to my USB and Charging ISSUE
PLEASE HELP ME, I am lost
Still the same. It's booting fine, USB2.0 no reaction on the laptop in Fastboot/Adb/Mtp ... On USB 3.0 Device remains unknown with strange Device ID String in windows 10 hardware Manager... Forced the old formerly working driver, but Odin can't find it anymore... Adb, Mtp, fastboot don't work, no communication... USB Cid is hard bricked, Charging never works in no state, just showing up for a few seconds in off state while plugging it in for short.... Bootloader must be damaged, fastboot and twrp can be started with dead USB... So is there a way to run a boot image to fix my bootloader from SD card, Aroma, or like OTA Updates are flashing? If Samsung and Google apply bootloader updates over OTA and simply restart, why we can't do that??? I need a new bootloader, is there any way without USB?
Greetings,
Thank you for using XDA Assist.
I have moved your question to your device's Q&A forum. You'll receive expert advice here. Good luck!
Fixed!
The problem is the USB Connector Port itself, figured it out after bending the inner contacts up with a flat screwdriver and cleaned them. Before that i always tried the same gently with no change, but please do it at your own risk only. After searching for many hours about possible reasons for the problem, I came to the conclusion to even compromise the Port and heavy bending it up, now it's charging! I will exchange the port soon and change the frame too to have it back like as new... OK, if anyone in the future have problems with the bootloader or USB hardbrick n910c, feel free to ask me, I upgraded my knowledge on many causes now
Thank you very much
My 2cents stick to one charger. Do not share that charger with others.
The worst culprit are the cheap china car chargers.
I went thru two USB ports on my first phone to figure this out.
Ever since I have adopted the policy of using only one cable. Never had this issue.
Ok so i had a Nexus 7 2012 installed into my car dashboard.
Some time ago the tablet stopped charging. I assumed the usb port was broken (had to jiggle it to charge sometimes) so i went ahead an tryied to clean it with a niddle while it was still on (stupid, i know). It still didnt charged and i tryied to power it off. It powered off and then it came back on. By itself. It was strange. I tought i short circuit it so i pulled out the battery and went to buy another daughter board for the usb charging port. The daughterboard came and i replaced it. Same problems.
Then i assumed it was a software error (the tablet had an unofficial lineage os installed). I booted into recovery and whiped cache + factory reset. Then the tablet went into bootloop. Powered back into recovery and plugged in the usb to the laptop. Surprisingly the laptop recognised it. I used Nexus Tool Rootkit to go back to stock rom but even after going back to stock rom, the tablet still wont charge.
Any ideeas on what might it happen ? How to fix it ?

Hello there have you been able to fix this?i am currently in similar state
Hi, I really need help. three months ago, some weeks after my Mi 9T overheated on sun (don't know if that has some relation to the issue), it suddenly stopped charging while on, unless I rebooted or turned off. Also, it had difficulties to transfer files to PC and connect to a flash drive by OTG.
Then, I took it to a guy and he said I needed to replace the charging port, and so I did. But only now, after a serious issue. I was changing my rom from MiRoom (MIUI 12) to Evolution X, since the MiRoom's developer ended the rom's support. But It didn't work, It boots into Fastboot mode. I tried to connect to PC and OTG, on recovery mode, but neither worked. The PC doesn't recognize my phone, and the OTG flash drive isn't recognized by the phone.
I bought the charging connector online and paid that guy to replace it. The port feels better, the connector feels way steadier when pluged in, but I still can't know if it charges while on and file transfer to PC or OTG is still not working. So, I'm stuck on recovery mode, in a rom that doesn't boot and a USB port that doesn't work properly. If anyone has a clue of what part I might take to replace or a repair, or maybe a software solution, if that's the case, I would be really thankful.
