    4CH DVR boot stuck

    By software you mean the bin files that i try to flash? Well dvr is up and running, can see the cameras, can do almost anything except save the settings. If i change any setting it looses it after reboot, the same thing is when i try to set it by uart with setenv command. This is the version info it shows me. Bin file was for model AHD7004T-EL. I believe that it has a corrupted eeprom but that is my opinion only. What is yours, and please explain to me what you mean by the word software and what by the one firmware. All the bin files i try and flashing is the firmware, and inside the bin file are the linux kernel, the boot logo, the custom functions library and the web interface files. All theese files are written in flash and in onother section in the flash is the enviroment declares. If i delete 256kb at position 0x400000 then i delete the enviroment and on boot uses the default one that i believe is in the eeprom. I can imagine what else the eeprom may contain... What am i getting wrong here? Thank you for your time.

    An update Hello, after some hours tested all variants of ahb7004t model. Many of them brought the dvr back to life but on all of them except one i had the same problem. Dvr booted ok but couldn't get in the menu, every time i pressed a menu it hangs, freezes and reboots some minutes later. With one firmwares i had the problem that it didn't store settings. I think that all i have to do is delete the environment but don't know at what address is in the flash and the command to do it. Also my board has an eeprom 24c08 that i am sure the version, model etc is in there but don't know how to read it via uart. Is there any way? Thank you

    Last question, again, i don't want to buzz you. Every zip file has two files, should i flash the bin or the image? Could you explain? Thank you

    I know that what you may didn't understand is that the dvr is not booting. Managed to boot it with the 00000117AHB7004T-EL firmware but i can not access menus. What i try to do is find the correct firmware by flashing all i find. My question is this, every zip file contains two files, a bin and an img file. What file should i flash to dvr via uart and how? Uart is the only method i have access to the dvr. Thank you

    How should i flash the firmwares? Should i flash only the update.img? i do it from uart with run up for update.img? What is the correct way to load the firmwares? Thessaly where i live, but in generall if you exclude athens that is the avg price almost everywhere Thank you.

    Here in Greece a dvr unit like that one costs about 110 euros. Avg month salary is 420 euros so yes if i can fix it for my customer i prefer to do it + i want to learn from it. Can you please explain to me why all firmwar files has an img file and a bin inside? What i do is extract the bin, flash all images from inside one by one and at the end i flash the update.img, is it ok? Thank you

    Well, didn't knew that but the firmware i used is the V4.02.R11.00000117 AHB7004T-EL, with this one boots but no menu and hangs. Should i go with another one by trying? Thank you

    First of all i have a bin file that supposed to be from that board but i don't know how to flash it. Can't extract it like many i found from net, the one that sent it to me told me that is a flash dump from his. Don't know much about how... Any ideas about that bin? Now, to the wizard i pressed cancel, menu apeared and if i press any sub menu will just freeze, but even if i just don't press anything it will reboot after some minutes. I was using vmEye on android and cms on windows. Could login from Chrome also on port 80. U-Boot 2010.06-svn342 (Jan 20 2016 - 19:33:32) Check spi flash controller v350...

    Cant get in the menu, dvr doesn't go in menu. I agree that hardware is also different that is why i showed you my hardware. Here is some photos of the real one also. Board Is the same as AHB7004T-EL as stated in the link. Anyway i guess that no one can help me unless he has the exact same board that has a sticker MBD0199A 2017-6-10 Just one last question, can i erase the eeprom from uart? Thank you for your time

    Yes as stated my board is AHB700XT8-3520D V4.03B 0197166178 and a sticker on it says MBD0199A but i can not find a dump from the exact same one. I don't know if it is a 1080p or 720p one, i believe this has only to do with the firmware, if board is the same for both. The link with the tecbox is just for a visual from the dvr, just a reader to see it outside. The second one from where i got the firmware shows the exact same board as hardware. When u say software you mean the custom-x.cramfs.img, the rom.cramfs.img or what? The 00000117AHB7004T-EL suits ok, the dvr starts but it hangs on any menu press or after 10 minutes it reboots even if i don't press anything. Maybe i must erase the eeprom before flashing it but i don't know how to do it from the uart. Have you something to suggest? Thank you

    Thank you for your time. The two photos with the one sata are from my board, the one with the two sata and the broken header is wrong, just can't delete it... Wilth the firmware of the last link dvr came to life again. Now the problem is that when i click on any menu it freezes and reboots. Both firmwares did the same, the link has two firmwares (00000117AHB7004T-EL and C6380117AHB7004T-EL). The first one was the original one. I posted here because maybe someone had the same board to help me find the firmware. I flashed via uart the update.img and everything in the bin file after i extracted it. Why it freezes and reboots i can no understand... Thank you

    Nobody has experience with flashing? Maybe somebody has the firmware to flash from tftp. Thank you
