Problem with a Shenzen Kaier KR-7005 wich gets stuck on the android logo at startup

Hello everybody...
Please sorry for my poor english please
I have a problem since few months with a Kaier KR-7005 after a battery problem of the car that had discharged : when it starts , the Ford logo appear at screan and the Android logo few seconds later, and it remains in this state.
If I unplug the KR-7005 from the battery, it does not change the problem...
When i look at the GPS SD Card, i have this file structure, and impossible to open a directory (excep "LOST.DIR") :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I think files are corrupted, and I 'm afraid I have a problem with the android system too.
But impossible to find a firmware to flash the KR-7005, and impossible to find the key combination to restore Android (when I press the RESET and POWER keys simultaneously and I release the reset , I get "Update Start" and "Update END" immediatly, but no option to restore android).
These are the specifications of the device (I opened the KR-7005 to view all references ):
Android Board : MST786 - A7MK869D - 1401B
MCU : STM8S207 ST
Sound Effect Processor : BD37534 ROHM

WIFI: RTL8188ETV Realtek Support 802.11b/g/N
Power IC : TDA 7560 ST 4x51W BTL Audio Power
The motherboard seem to be the same as the KR-7025 (wiki here : http://forum.xda-developers.com/wiki/Shenzhen_Kaier_KR-7025),

Does anyone have an idea to solve this problem please ???

SuperSU binaries update disables SIM options

Yes it is weird and it cost me a lot to localize my problem but it looks like it is like the title lays.
Smartphone: ZTE Nubia Z7 mini (NX507J)
ROM: Stock 1.82 based by [email protected] Link: http://www.needrom.com/download/zte-nubia-z7-mini-4/
Android version: 4.4.2
SuperSU Free v2.78
Update mode: in-app normal
Root after: Intact
I noticed suddenly that I couldn't access to my SIM options like unlocking pin, select ringtone, etc. Since i already had the SIM properly set up and it was functioning properly I didn't pay much attention but it has come a time when I have to use the dual SIM card feature and have to access the options. The only thing I could do after a factory reset was reflashing the ROM. After that I could access the SIM options of both cards without problems. I set up all my backups and then realized again that the issue was repeating.
A new reflash and then I was checking the SIM options after every step I did to know what was causing the bug. It turns out that it was after updating the SuperSU binaries.
The weird thing is that despite the phone shows 'no cards' it can send and receive calls, mms, data, etc. So, if you had set up properly the cards before the bug you can use them. But you cannot select with which card you want to call or use for data (always card 1) which makes the dual card function useless for my job (I don't want to call from my personal phone for obvious reasons).
This is a screencapture with some indications. It is full size and that's why I hid it

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I would appreciate any ideas or guidance I could apply to solve the problem. Thanks!

I fixed this by uninstalling the updated SuperSU app. It reverted to the older one which worked fine. If you cant then try downloading an older version and installing that using TWRP or a file explorer.

Deleted all SMS! - Recovery Options? - unrooted Android 8.0.0

Hello.
I was deleting 2 SMS messages, I did long press on the 1st until the blue tick appeared then selected the 2nd SMS.
I then quickly went to the top 3 dots to select 'Delete' and the next thing I saw is blue ticks all the way down the right hand side of the screen with 'Deleting' on the screen.
The screen refreshed and it was blank - all SMS messages deleted :-(
What are my options to recover them?
I have looked at apps like Fonedog & Dr Fone but after they connect they state root is required.
I was not using Google backup and had just tried Mi Cloud backup/sync a few weeks ago but with just photos selected.
My phone details;
Model: Mi 5
Android version: 8.0.0 OPR1.170623.032
Android Security patch level: 2018-10-01
MIUI version: MIUI Global 10.2 Stable 10.2.2.0(0AAMIXM)
In Developer options:
OEM unlocking is greyed out but it says "Bootloader is already unlocked" underneath (see screenshot below)
Mi Unlock status says "Unlocked"

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Your help and suggestions greatly appreciated - I had some sentimental messages I would definitely like to recover. I have removed the SIM, turned off Wifi, turned on aircraft mode and phone is turned off unused.
If the bootloader is already unlocked - could I try to root the device (with low risk of data loss) then try Fonedog & Dr Fone recovery again?
When I first got the phone I tried Kingo-root and similar apps but they failed to root the device. I didn't take it any further at the time.
I know, I know, about backups and have already berated myself. I'm very careful deleting things and this Mi 5 has worked beautifully in the time I have had it. I just don't know how it could have happened. I promise to setup a daily backup/sync once I get over this.
Thank You.

Question Urgent question- Mi 11 Ultra 4G/5G issue

Hi guys, I'm so happy to join the mi community. Please help me with an urgent connection problem on my new 11 ultra.
It shows "LTE/5G" on the right top, next to the battery sign. However, I do not get any data (browser/chrome) on my phone.
Does it matter with unlocking or not? (because it shows LTE sign but does not actually get anything)
Can I solve it by install EU rom or Global rom?

Carrier: (GSMA/ATT) Red Pocket Mobile
Model: M2102K1C (Chinese version)

Answer is simple, search for your carrier APN details and update it manually. You'll have everything working perfect, the only issue is you have to repeat it at every factory reset or rom change. But do not worry if you'll keep the same rom at all times.

When you add the new APN, don't change existing one, just create new one and use it.

Also, seems like you are not on latest software update. Try to update your device over wifi, maybe new settings are added to your new software and you do not have to do it manually

@hassanaliyeh. Thanks for your prompt reply! Tried all apn setting above, still doesn't workk..
Don't know whether the main problem is "Red Pocket Mobile"

Also try to do reset network settings. Might work.
Have you tried different browser? Could be another reason
