johnyp 1 Posted March 13, 2019 Hello to everybody, Last year i bought a china unbranded dvr width 4 channels. Was working ok till yesterday but suddenly stoped booting. Now when i power it up all it does shows some vertical color bars and stucks there. I removed the hdd and the smos battery but still no change. The board is AHB700XT8-3520D V4.03B 0197166178 and a sticker on it says MBD0199A. Is there anyway to reset it to factory or maybe reflash the firmare (i don't have the firmware, must find it) via tftp from lan or form usb on boot maybe? I also trying to find the TTL UART but no luck... My dvr is the first two images named 538..., the last one with the broken pins and the two sata is from net and uploaded by mistake and don't know how to delete it. Thank you very much.

johnyp 1 Posted March 15, 2019 Even if nobody replyed yet i think that my board is this : http://www.xiongmaitech.com/en/index.php/product/product-detail/2/93/186 Still if anyone knows better any help would be great. Thank you Share this post Link to post Share on other sites
tomcctv 190 Posted March 15, 2019 Hi. Guess work is not good ... you have listed 3 boards that are all different. Firmware willnot help your problem you need the software that works with your board....... the software needs to be working to use firmware Share this post Link to post Share on other sites

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 Share this post Link to post Share on other sites

johnyp 1 Posted March 16, 2019 1 hour ago, tomcctv said: That board is used In hundreds of dvrs all with different software your link 720 AHD .... last link 1080 ywo differant units 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 Share this post Link to post Share on other sites
tomcctv 190 Posted March 16, 2019 It would be much easier to load pictures of your units screen menu then people would know who’s software what app was used when you got your system Share this post Link to post Share on other sites

In that case no one needs to upgrade there units to go from 720 to 1080 ..... this is not the case hardware also is different Share this post Link to post Share on other sites

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?

johnyp 1 Posted March 16, 2019 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.

johnyp 1 Posted March 16, 2019 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 Share this post Link to post Share on other sites
tomcctv 190 Posted March 16, 2019 Hi. Like in first post you will have to go try them all till you find one that matches the software Xmeye vmeye secyour idvr....... But if do find it ....it will only be a 720n unit DVRs are cheap is it worth all this Share this post Link to post Share on other sites
johnyp 1 Posted March 16, 2019 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 Share this post Link to post Share on other sites

That is not going to work ......... You can't make your own firmware from bits of everything.

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?

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.

tomcctv 190 Posted March 16, 2019 I do understand ......you stated it in first post . i sent you the link so you could go through all 56 firmwares with instructions its going to be like doing a jigsaw ....... You may get it to work ....... But when people start to alter any software then it is usually for the bin Share this post Link to post Share on other sites

Could you explain? Thank you 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?
