I don't think it will shorten it's battery life when you replace the battery. I mean as long as you get the right battery should be completely fine. Pretty sure it's just a clip-on mechanism like you just clip it off like take a little piece of plastic slide around the edges. Then once you get inside the device then you just have to desolder the connection to the battery. And yeah you can replace the battery with a normal I don't. I don't even know what the heck. And yeah it's I'll tell you one thing to make the speaker work. You going to have to align the board back up properly? Otherwise it shouldn't affect anything else with the tile

@@DukehsuPhdo you have a link or further description?

But the firmware from Dabmann 200i worked well on Sky Vision DAB 70 IR. Only the physical buttons were swapped around and so was the remote control. But you can correct that with the original configuration files. Or you can play around a bit with the data sets in them. (Buttons: "/flash/KeyPadMap.cfg", remote control: "/flash/IRMap.cfg"). I'm still considering whether I do maybe install the firmware from Dabmann because of Spotify.

Hello DC2NI, It is difficult to assess malfunctions without seeing the device in front of you. But I agree with your approach to the problem - it’s worth starting with the power supplies and how they are distributed across the board. Indeed, it often happens that the cause of the malfunction is secondary voltage sources (DCDC, LDO, etc.) Just choose a search strategy and go with it. For example, if possible, find a document for your CoC and check for the presence of supply voltages (or if they are too low, etc.). Best regards, Alex

@@alex-loghi Finding the documents to my Coc and check the voltages is a good advice. Despite that I will change nearly all capacitors on the powerboard anyway. Thanks for the advice and for this interesting video. Happy Easter

Hello magicarpetmoto, at 3:01 you can see the circuit diagram for connecting the piezo crystal. It shows that the piezo crystal is controlled by piezo driver IC U3 (MAS6240C) based on a charge pump technology. The outputs of this driver are marked on the board as Z1 and Z2. Best regards, Alex

@@alex-log thanks!

if IC9 = U9 in dabman i200 with marking S5EGH SOT23-5 then most of all it LDO. Output of U9 goes to VDD18 (assume +1.8 volts) pins SoC. If you have nothing to lose, get the datasheet for this chip and try lifting the pins labeled *VDD18* (VDD18, MVDD18, UD_VDD18, etc) one by one until the SoC (and/or U9 also) stops heating. Good luck.

I can't advise without seeing the device in front of me. If you have enough skills and equipment before starting any actions make a backup copy of flash memory on the programmer. This is mandatory. Then you can experiment with any other version. But before you do anything with the software (even in this case it is advisable to make a backup copy of spi flash) check the power supply (possibly by replacing the power supply), and also check the electrolytic capacitors (some may have blown or lost capacity) - this may also be the cause of unstable operation. Regards, Alex.

Update: I sent email to Dabman support team and they send me improved Software which I could install from USB. Maybe please add note that People should contact with Dabman support team.

@@piotruxd3412 I have pinned your message. Indeed, you are right. It is best to contact official support first. However, I made this material for those who have nothing to lose, the firmware files are in the video description. Thank you for your attention.

I know of at least two ways: 1) use vpn tunnels (vtun, wireguard) 2) third-party service ipeye.ae, which has a free tariff option. For more information, please visit the telegram group t.me/openipc

Better just stream to RUclips so u don't need to open port

There is no obvious way to roughly open the u-boot console. sometimes it is impossible. There are many already known passwords - try googling the user gabonator on github gist (gabonator ip camera password gist . github . com / gabonator / 74cdd6ab4f733ff04747356198c781f27d). Other ways involve unsoldering the chip and reading it on a programmer and then searching in the dump, but you need to know where and what to look for (also not always 100% guaranteed). You can also join the OpenIPC EN group in telegram t . me / openipc and show a good quality photo of both sides of the board. There are more experienced professionals there who might recognize the board, the manufacturer and maybe the password is already known. Good luck!

@@alex-log I am already on the group. It is very informative. But I in one link I show we have to short DI and CLK pin of flash. And burn univarshal u-boot. For my board it is GD25Q128 and I have similar SI and SCLK pins in chip. when I short it, board stop booting. But I can not flash the board. I have Hitool application but not succeed.

@@unknown-bc3uh Don't hesitate to ask questions in tg group, it's more productive ;-) Yes, there is a way to short DI and CLK pin of flash, but it is more like a hack to stop the boot process, for example if the timeout is set to 0. But shorting DI and CLK pin of flash does not help to ignore the password, so in your case it will not help. About Hitool application - it is designed for Hisilicon (Goke) SoC. If you have SoC Hisilicon (Goke) then yes, this is your option. Then it doesn't matter if you have U-boot password or not. You load U-boot in to RAM via Hitool application and run the commands you need, including backup, OpenIPC U-boot flashing, etc. I recommend you to show in tg group a picture of your board from both sides, maybe there is a different SoC.

@@alex-log thanks for advice 👍

It's easy just directly erase the flash and write new bl to it with ch341a

Its the TN9SHC6A

Hi, I do not have firmware for this particular model. Everything I have, I attached in the video description to the google drive. I have an assumption which I want to check on the reason why this happens: maybe there was a power failure or something like that when writing to the SPI flash IC and as a result a corrupted settings file. My plan is to connect via SoC UART and try to delete that bad looking settings file (making a backup of course). Maybe the application will recreate it and it will be correct and all the problems will go away. Or I will try to add this file from the factory firmware (via mounted USB pen drive). I assume they are relatively the same for the entire model group, but I could be wrong. I'll probably do a second part on this radio and show what I got. If you can dump it with a programmer please send me an email whith dump to iamalexlog@gmail.com and I will try to analyze it. If I see the same problem I will let you know about it in the reply letter but I can't promise that it will solve the problem. At least we can try to solve the problem. Thank you.

@@alex-log Hi. I ordered a programmer. As soon as i get it is will extract the firmware from the spi flash. And yes. The 5v rail on this device died ( specifically the FR9888). Which i repaired. After this the fault appeared

@@proditaki does a voltage ~1V mean that the FR9888 is dead?

@@slie052 on the output? Then yes. Should be 5v
