I've bought that cheap chinese device, is ""branded"" as D35 pet tracker, unfortunatly it does not work but I think that it's a configuration (APN) issues and not a device fault.
From the beginning:
- The device does not connect via gprs but is possible to call the device
- Connected to the PC is recognized as a mediatek serial device, after some tries i've found that it responds to AT commands, unfortunatly not all... And unfortunatly not the ones that are gprs (2G) related...
- After some search I've found that the board is a Gainstrong Oolite S1 (Based on MT2503), I've contacted the manufacturer but at any question the answer is a brochure of other products (why I'm supposed to be interested on the new S3 board if there is no support for the S1)...
- That board is suitables/used also for smartwatches so that thread can be also usefull for who get that cheap devices
- Following threads for similiar devices i've read that manufacturers changes/personalizes/delete default at+commands and the only way to get that is by unpack firmwares ("d35" manufacturer is unknown, board manufacturer does not give answers )
- Following the steps on another xda thread i've succesfully extracted the firmware :laugh:
- NOW, how can I decompile/unpack the obtained firmware files? Has anyone heard about custom firmware for that board?
Thanks
Set APN with command "APN,apnname,username,password#" (send by SMS without quotes). Username and Password are optional.
Hi, I know this is an old thread, but did you manage to get your D35 tracker working. I am struggling to send the APN settings.
Thanks

hi
I bought prevents this smartphone, after rooting, I noticed that the connection would jump, after some research I read the router manual for specific devices that the mac address must be in some range of values, so it must be changed on Android .... following the procedure of the lg p500 does not change ... what can I do?
thanks
anyone can help me? please
Help is subject to someone on-line actually understanding your question and having an answer .
I bought prevents this smartphone >>>>> not a clue what you mean no such app on the market .
jje
The mac address for each and every network device is embedded into the device.
So there are 3 possibilities:
The wifi chip in your SGSII is faulty and is telling the O/S the wrong details - send it in for repair.
The Android O/S has corrupted and is reporting the wrong mac address - reset the phone to factory settings (wiping everything) or flash with a wiping ROM. If still unresolves send in for repair.
The phone is stolen and you are trying to hide its true identity from being traced - no help from this site.
After a long research i decided to create this thread!
After na update my Optimus L3 got in a "No service" situation. The strange part is that i have signal and im able to acces the internet using mobile network (wifi off). After a long research i fugered out that my IMEI was 0 (zero). I finded a lot of solutions to this problem but none of then was compatible with my device or brand.
Its possible to perform this in an Optimus L3? How can i acces the Port Settings?
(ultimate solution for several LG devices)
Restoring IMEI
1. Connect phone by USB
2. Activate USB debug mode
3. Enter 3845#*920# in dialer if that doesn’t work try 3845#*925#
4. Select Port Settings -> Select CP Image Download
5. A new device should appear at let it install
6. Open Tutty and select serial protocol. Click on open
7. Type AT if response is not OK, change port number (it is possible that when typing you don’t see any letters)
8. Type at%imei, it should display a dummy IMEI
9. Type at%imei=x,x,x,x,x,x,x,x,x,x,x,x,x,x,x where x,x,x... is your orginal IMEI number (found under the battery of your phone). It should response IMEI WRITE OK
10. Reboot phone

Click to collapse
sorry for my grammar!

Dear All,
I have come across several threads regarding the IMEI null issue and have seen solutions but most of them dont actually work except where Z3 box are used to rewrite the IMEI.
Some threads I have seen that another similar device is required to copy the IMEI from 1 rooted device to another rooted device via FileExplorer, but nobody has mentioned the next step as to how to set the IMEI null device's IMEI back to its original after copying from another device.
Please let me know as I have 2 rooted device both of which are mine.
Both devices are GT-I9505.
Thank You
Appreciate your support.
Hello XDA, I have been a user/fan of xda for about 5 yrs now. But I havent found a single problem that I didnt find the
answer for here on xda, or somewhere else (Google). I have a Computer and Phone repair shop in Ethiopia and I used the
internet and mostly XDA to Unlock Sprint HTCs, Unbrick Galaxy S/ SII/ SIIIs, repair corrupted efs partitions, install
custom roms like CM (on almost every smartphone I come around), fix bootloops of Best devices like Xperia Z, Galaxy SIII,
Sim unlock Moto Droid ...
But I have faced a serious problem and have been trying to solve it for about three months now.
To the real problem
There Are these MTK MT6582 Devices, Mostly Huawei devices (G730, G610, G630) and they are recently getting a major IMEI
failure (IMEI : null). I have tried through the ff methods (that I use for other MTK devices like MT6572, MT6575) With no
luck
1. Maui Meta 3G - It reads the devices in meta mode
- It can read the version (in "Get Version" window)
- I have selected the Nvram database of same baseband
- It fails to write the imei when I click "download to flash" It either replays "Check the load and device versions are the same (ish)" or "Download to flash time out"
2. IMEI & SN Write tool - Doesn't seem to read the device in meta mode.
3. MTK Droid - Rooted the device
- Restored "nvram" from another working phone
- Rewritten the IMEI
- Still the same (IMEI: Null)
4. Reformatted the whole device and installed firmware with "secro" file - Still the same - tried the above methods again, still the same.
Dear XDA Fellows, I am exhausted with these devices and they are keeping coming. So, Please help me solve these problem. Thank You.
P.S - I dont know where to post this, if there is another appropriate thread, lead me.
Hi,
I own a m7350 v4. In Switzerland you can get a multisim which allows you to use unlimited contract data on more than one device. But they detect lte modem/wifi hotspots and shape the traffic down to 0.5kb. They only allow you to use the multisim in phones or tablets. When I put the multisim in my phone, I get full speed.
Somehow they read out the vendor and model type of the device, it also shows on their webpage in my userspace.
I looked into the firmware and in M7350(EU) 4.0_1.0.11 Build 180119 Rel.1090n_User/system/etc/default_config/product there is the product config section:
config product info
option board_type "mdm9207"
option product_type "m7350-eu-v4"
option product_id "73500004"
option product_name "M7350"
option hardware_ver "4.0"
option firmware_ver "1.0.11"
option firmware_ver_build "Build 180119 Rel.1090n"
option product_region "EU"
option product_series "M7350"
option vendor_name "TP-Link Technologies Co., Ltd."
option ssid_prefix "TP-Link_"
I tried to change product type and series to a phone type, because the router is running android, repacked it and tried to upload it.
Obviously this does not work because the firmware is sure as hell checksummed.
Is there anyone who knows how to get the changed firmware zip to upload and update, where is the checksum to rehash or how is the checksum/integrity process working?
Thanks for your help,
New to Android hacking,
Best Mike
TP-Link M7350_V4.0 (EU) Firmware
Hi Mike,
I recently acquired a TP-Link M7350 V4.0 in UK and in the process of messing about with it with a phone SIM card on EE network, I may have 'Bricked' it ... a bit! Obviously this will now be out of warranty now I expect.
Last night, I downloaded the GPL Source Code from the website and unpacked in a laptop runing Ubuntu 16.04 LTS to see what can be done to compile it. Not planning to do that soon, but any leads would be welcome.
Did you use the adb sdk tools to get into the M7350 for the Product Info? I don't think I have that installed now, so I'll need to download that all again I guess. What 4G LTS carrier SIM are you using? I was thinking of getting an O2 SIM with plenty of data before this disaster - supposidly, V4_171208 firmware supports this carrier, which is 'on-hold' now. I'm still showing Firmware: 1.0.5 Build 161110 Rel.1040n, and cannot seem to update.
I'm now thinking this is not a very mature product ... sadly.
Regards,
Richard
