BOM Selection switch (SW1B1) has been changed problem! Please help - Teclast X98 Air 3G

Dear All
After flashed wrong BIOS file My Teclast X98 Air III could not be booted into DNX mode.
When I press Volume +- and Power, a message "BOM Selection switch (SW1B1) has been changed but can not take action, system will reset in 3 seconds...''
Then, it goes to Aptio Setup Utility with boot option. Unfortunately, I tried many options with this utility without success. It seems to me that the utility did not work since my "changes" have not been applied.
Now, the desktop does not recognize the tab when it connected. So, there will be no more flashing.
Please help me to solve this issue.
Thank you for your reading.

i have same problem. Did you have solution?

KAIS130 unabled to communicate with PC

Hello everyone,
I am having problems to connect my Tilt to my pc.
First of all, when I power it on, the screen goes black and says "smart mobility" .. so far so good; but after a few seconds it starts again and loops endlessly. At that point the only way to power it down it to take the battery off.
I installed the drivers manually (Vista) and hoped to be able to use mmty (after pressing "camera button" and " power button") but I never managed to get a connection.
Does anyone have any ideas on how to get my HTC tilt back to a running state?
Sooo, this only happens when connected to the PC or all the time?
It happens all the time even when not connected to PC
I forgot the most important part ... this happend since I tried to update windows mobile (source downloaded from HTC official site).
Hard reset?
if you mean holding down both green and red headset button+pressing the reset button, yes I've tried that but didn't change anything.
It went through a whole process and nothing changed? Try to flash back to an oem rom. (seems to be the new popular suggestion).
ok but how can you do that if you can't get to connect it to a PC via usb?
By following the proper steps to flash a phone either by usb or SD card.
The phone doesn't need to be fully booted to flash.
Ok, that's good news for thanks.
If by any chance you have a link to a tuto in order to do that you're welcome. Otherwise I'll google it and get back to you to keep you posted.
It's all in the sticky

Thanks I shall try to night
Thank you for your time. I finally managed to do it and my HTC is back to running.
The only problem I had trouble to solve (if it can be of any help to anyone) is that I had to unrar the *.exe which I didn't could be done.
Thanks again

Bricked! Only Phone+Triangle+PC error symbol, won't turn on :(

I think that this problem has already been discussed before, but I could not find an answer. My skill level is too low...
My TAB is a Hong Kong Retail version, which is unlocked.
After successfully rooting my TAB using Z4root, I installed BootStrap for EURO TAB and then I could successfully install Paul’s Modaco R1 version. I did not experience any problems. Then I installed Richard Trip’s Kernel, and I am not sure if something went wrong (or was already wrong), but somehow I could not get access to the Market anymore.
So I decided to reinstall Paul’s ROM using ODIN, but somehow after a successful start, there was a red FAIL. I guess i probably used the wrong setting and fell into the protected boot trap? I tried to get into the boot mode again, but could not get in.
After many tries to get into the boot mode, I now have:
If connected to an adapter: there will be a phone+triangle+PC error message. Sometimes this message will stay on as long as the TAB is connected to the power adapter.
Sometime the phone+triangle+PC error message will get flash slowly.
I tried to leave it overnight and then charge it and get into Boot mode, but no success.
If I try to attach the TAB to a PC or Notebook, nothing will happen. Nothing will happen even after several hours.
So … what is the best way to solve this problem? Please help.
hi,
read these two threads, maybe it can solve your problem.

good luck.

I did a hard reset and it worked...
Samsung Galaxy Tab: Steps For Hard Reset
by Mitch under Android, Hardware
A hard reset will reset the Samsung Galaxy Tab back to factory default settings. You would perform these steps if you want the device prepared to sell or return to the store, but you may also want to perform a hard reset if there are problems with the device that you can’t seem to solve using any other method.
Note: These steps clear data from the device. SD card data like your photos and music are not erased unless you choose to format the SD card.
1. With the device off, press and hold Volume Up and Power.
2. Release the Power button when you see the Samsung logo, but continue to hold Volume Up until the recovery screen appears.
3. Use the Volume buttons to navigate the menu and select wipe data / factory reset. Press Home to choose the selection.
4. Press Volume Up continue.
The Galaxy Tab should then go through the hard reset process.
If you have access to the OS, you can also perform a hard reset in Settings.
1. Open the Settings app.
2. Select Privacy.
3. Choose Factory data reset.
Hard reset probably won't work as it sounds like a bad flash... Any OS you flash will replace your stock OS which is why people say to backup EVERYTHING...
Right. A hard reset (if it works) removes user installed apps and their data. It won't restore anything, but it should return any user-made settings to the default.

Please help in translating this logcat

I just recently switched from HTC to this Galaxy S3 i8910 mini and in some kind of a problem.
The phone would reboot after a period of time in NORMAL mode. I think an app installed is triggering the event, after the reboot any changes you made would revert the phone settings files to it's last state (kind of similar to Windows TEMP profile) wherein it is not remembering or saving any changes made to it.
I have tried anything I can find in the internet including flashing variou PIT and TAR files but none worked. So I tried grabbing a logcat and just let it run until the phone does the reboot.
Currently the phone can boot to SAFE mode and will not boot not until I try to uninstall ANY application that was downloaded by the previous owner. Worth mentioning also that even after factory reset and performing wipe via stock recovery is of no help at all. I can get to download mode and recovery mode with no problem it's just with the reboots and reloading of it's last state is the problem.
I am suspecting that this thing maybe suffering from a bad NAND set to R/O but I can't conclude yet until I can have the logcat be read by someone who knows how to. I am not a developer knows not much about codes so any help will be appreciated.
I have read about this issue in this thread http://forum.xda-developers.com/showthread.php?t=2562596 and found no solution yet so I am trying my luck if there is anyone that can help. TIA. :highfive:

Hi efaustino,
First of all thank you for taking the time to respond. About the time, I am unsure of it. I normally happens within a time frame of 2 mins or less from the time of first boot.
In addition to that, I have recently tried re-flashing CM 11 from @mcclaw and got a message in download mode that says movi_write card status:2 (1) start_blk:6144 in red.
I have found out in even in SAFEMODE I am able to recreate the reboot by making the phone read the internal memory information, such actions would trigger a reboot:
Within Settings:
-Going to Applications Manager
-Going to Storage
-Uninstalling any application in safemode

something wrong with the locations it tries to reference from memory
when you tried the various pit files etc did you select re-partition when using odin?

I was too busy with work and only got the chance to check your response. Yes I did, I even tried wiping NAND but to no avail. Re-Partition with only a pit file in place will show successful but when a .pda file is placed together with the .pit file Odin will fail in writing to NAND.
With NAND wiping checked, Odin will get stuck in Erasing for a few minutes and would just fail the process. I'm running out of idea on how to turn this expensive brick to a phone again. :silly:

SM - G780G - Screen flickers

Hi all,
My wife just bought the G780G.
I configured her device using Samsung smart switch, and used it to transfer settings, apps and data from her old S8 (first time I did it, usually I prefer to start a new device from scratch...) .
She says she has an issue with the device - sometimes, while using it, the screen flickers...
I didn't see it exactly and she didn't manage to reproduce it to show me, but she says it happens to her quite a lot.
Anyone familiar with this issue?
Any solution you know of?
Thanks!
long shot, if she uses chrome try updating it and android webview along with it. there was an issue months back where that caused system wide flickering and some apps not to work.

I updated Chrome.
No update was needed for Android web view.
Unfortunately it didn't help.
The issue persisted today...
I suspect 2 things:
1. A firmware update that was done yesterday morning (my wife doesn't remember if she encountered it before, she have the phone for 2 days...)
2. Restoring data using smart switch - it can cause issues? I restored the data from her old S8.
Can it be that some corrupted data was transfered?
I'm thinking of factory reseting her device and let her start from scratch..
What do you think?
before you reset try booting to recovery and clearing cache. if there was an update it could be the cache. if it doesn't help then yeah reset is the next option.

Thanks man
How exactly to boot to recovery?
I tried after watching several YouTube videos but had no luck...
Edit : looks like something is messed up with this phone.
I'm not able to boot into recovery.
Doing this:
Turn off device
Press volume up + power button simultaneously.
As soon as I see the Samsung fe logo - I release the buttons - the phone boots regularly...
Booting this phone to recovery is a bit tricky:
1. Shut down phone and wait for a couple of seconds
2. Connect an USB cable to PC and phone
3. Push and hold louder button
4. Push power button until recovery mode will be shown
I prefer ADB:
ADB DEVICES
ADB REBOOT RECOVERY
I press volume up plus power simultaneously while inserting the connected USB cable.
Thanks guys!
Managed to do it after connecting to my laptop.
Just wiped the cache partition - hope it'll help..
Well unfortunately it didn't help.
The screen still flickers.
I'll factory reset the phone.
Hope it'll help and it's not a hardware issue...
consider also reflashing the current firmware. there's even a way to do that that doesn't involve wiping your apps. using the HOME_CSC file will keep your user data intact. then if that yields no results you can try a factory reset.

Thanks man but I don't know exactly how to do it...
I'll factory reset it and that's it.
Hope it'll solve the issue
I wiped the device yesterday.
Looks like the issue is solved.... No more flickering!
Not a hardware issue
Thanks everyone!
Hope it is not a hardware issue. Because my old s5 and pretty all samsung s5 have screen flickering problem especially in cold weather.
