Phone: Samsung galaxy S 4G ( SGH-T959V)
ROM: CM 7.1
I was using my gadget comfortably for a long time. Suddenly, i lost my mobile network and couldnt make calls. I tried to check network status in
SETTINGS->ABOUT PHONE. There was no help. The IMEI number seems to be lost too. i tried changing the ROM . The results were same. Please Help!!
Look in the development thread grab a one click from the heimdall one click thread and flash back to stock.
The problem is the computer does'nt recognize my phone.. In order to use HEIMDALL, a valid USB connection should exist for communication between the device and the PC.
i have installed all the drivers. Tried to connect with different cables and different platforms(computer). what can i do? Please help!
Have you tried a different usb port? I use the one on the front for heimdall and one on the back for Odin. Most would recommend the back ports.
Delete all drivers and let heimdall reinstall them.
Yes I tried everything. Is there anything I can do? Is there ODIN supported for this phone?
is there any flashable stock rom available for this DEVICE? PLease help!!
I bought a Cubot GT72 from the net - its basically a chinese knock-off with some very nice specs. And it was working great out of the box; but I had to experiment - right?
Edit: cannot post links; but if you got to www cubot net - you can find the phone easily. The stock ROM is also available.
I fired up MTK-Tools and rooted the phone - no problem there. Then I tried to create a custom CWM and install - that's when things starting going down the drain. It overwrote the recovery and boot partitions - so the phone stopped working. And since then I have been trying various ways to unbrick it.
Luckily, I have another phone with the exact same specs - and was able to download a backup using MTK-Tools and another one using SPFlash.
Problem - the phone is not switching on at all. When I connect it to the computer (after installing the MTK drivers) - nothing happens. When I connect without battery and keep the Up volume pressed - the computer detects an "MTK COM Port", installs it and within 5-10 seconds the port disappears, comes back after 5-10 seconds - and this cycle keeps repeating. I'm not able to connect to the phone using wither MTK-Tools or SPFlash.
When I connect the working phone - it shows up as "MTK VIA COM Port" and I can connect to it using SPFlash.
Have opened the phone and looked for test points - found one that switches on the phone and connects to the computer - but the result is the same as when I connect with the volume up pressed.
Please help - I'm at my wits end.

Ok Google "mt6572 com port drivers" and look for ***.ftdichip.com/Drivers/VCP.***, install the software off that site and see if your computer recognizes the com port, hopefully you'll be able to flash the original rom back to it, let me know how you get on :good:

Thanks Neo, The driver is installed - the problem I'm facing is that the phone keeps going offline every 30-40 seconds and hence am unable to flash.
okies
OK thanks for the reply. Its obvious these MTxxxx devices wait for a signal when you plug them in.
1.Try going to the SDK folder and open a command prompt, type fastboot flash boot "boot.img" > point the boot.img to where you have downloaded the original boot.img for the device.
2.When the fastboot gives you the [waiting for device] prompt plug in your phone.
Let me know how you get on, i'm going to be working on a program to flash these phones from windows. :good:
p.s if the above works then flash your original recovery as well

Hi Neo - tried. The phone gets detected, but fastboot remains stuck at [waiting for device]. Please see screenshot.
Also, I think the preloader is also gone
Diffrent Drivers
Ok i noticed on there website that there are a different set of drivers, where the ones you have installed emulates a com port the other ones gives you direct access to the USB port, go to adb and type adb devices so that your phone will show up in the device manager, uninstall those drivers and install these ones ftdichip.com/Drivers/D2XX.htm.
Then try and flash the preloader in the usual way, first type flash preloader {name of file} then connect your phone and hopefully you will be able to flash your phone again.
Let me know how you get on again :good:

Apologies for the late reply - tried your method - the phone gets detected as MediaTek DA USB VCOM port - but fastboot or SP flash are unable to detect.
Also, now I have managed to brick the other phone also. Was trying to upgrade the ROM from cubot's website. And even that one is bricked
Really frustrated here.

hi, did you manage to work out anything? i have the exact same problem with my GT72, and i'm out of ideas.
I finally gave up and sent it for repairing. The vendor has been trying to repair it for the last 2 weeks and has given up too. The problem with my phones is that they are not original cubot - the seller on aliexpress is selling fake cubot phones - and we're unable to find the correct files to write to the phone.
Now if only I could find a way to write back the ROM0 file without the scatter files - I had though that would be easy, but am unable to do anything about it

maybe i have a fake one, too then. wierd stuff, that is. faking a $60 phone...
anyway, i'm guessing you can only use that ROM_0 file to create a proper preloader.bin for the phone, but you need a working one for that.
you could do that in MTK droid root & tools, but since our phones doens't get detected, we're stumped.
i think having the right preloader could push us to the right direction, but i'm not planning to order a new phone to revive my dead one
anyway, if you make any progress, let us know!

I backed up the ROM_0 file from a working phone (had 2 - broke both); have uploaded it and shared in this thread. So, if you can create the preloader.bin from it - please be my guest.

i know you uploaded it, but the problem is that i can't do anything with it in MTK droid root & tools, since it only works if there is a working phone connected to the pc.

I had even created a scatter file using MTK Droid - the only problem is the scatter doesn't work with the phone. See if it helps you.

here's my "progress":
i was able to salvage a preloader.bin from your dump, this was the only one i could get flash tool to start preparing flashing.
i ran into numerous errors after that, but i managed to build a seemingly flashable rom, but it just does not work.
i could format the nand with it, but when i try to flash, it says that the bootlader exceeds partition boundary, whatever that means.
so i'm pretty much stuck at this point, but i'll attach the preloader for you, maybe it will work with your scatter.
the scatter btw did not work for me, since the addresses were wrong (i guess that scatter is for 512MB version, too).
so i built a scatter from scratch with notepad++ it's in the zip, too.
now i just wish there would be someone with a 256MB version able to make a backup with mtk droid and share with us.

Hi, the same problem, have you figured it out? Thanks for your help ...
This is my first time asking for help directly here, I always find the answers in the other threads solved, but this time I can not find an answer.
I have a alcatel one touch 5020t evolve its a MTK6575 (t-mobile but is used in el salvador), I used to MTKDroidTools to install CWM Revocovery, I did back up with the same program but apparently did not because i look and i cant find anything in the back up folder, only left some files called:
ALCATEL-ONE-TOUCH-5020T_130818__boot_patched_140129-175612.img
ALCATEL-ONE-TOUCH-5020T_130818__recovery_140129-175612.img
in the folder called recovery.
Now the phone on, the startup screen and then turns off, I can enter a menu by pressing on + vol +, where it says enter recovery mode or normal mode, before they tried to install cwm I could go in and delete everything from there, now I get the menu of recovery mode and normal mode but since does not enter recovery mode, got it turns off, like when entering the normal mode.
I tried to flash with sp flash tool but I get an authentication error that is on the img
The pc recognizes my phone, makes the sound when you connect something, now if we go to Device Manager, a device called first appears:
MTK USB Port
After that is disconnected and then a new one appears called :
Media Tek Preloader USB VCOM Port
But there ir a problem, then this becomes a repetitive one disconnects and connects the other, but only when I connect the phone without battery only stays in:
MTK USB Port.
Help what can i do to revive my phone ???????????????

Sorry, but i could not solve yet, nobody helps me
So were you able to flash cwm to the device? there are several threads requesting a custom recovery for this device and either way could you upload those first two .img files I may be able to use them to try to recover my device
*** Okay so the problem is that the boot loader on this device is locked and for the time being a custom recovery is not possible. I still have access to the recovery on my device so if I could find a way to build an update file from the source code or an official firmware update I could fix mine. Yours may be too far gone. sorry.
any luck with a solution? How close to one have you got to...

A friendly warning: Don't just mess around with the Bootloader, that's one delicate piece of software, try to find how to unlock it first, then we can talk of changing the recovery. For rooting purposes I can attest that you can safely root it using the OneClickRoot solutions around the net. I used some chinese root and it worked like a charm.

I have had a OT-5020T with all the same symptoms as you describe. After much research and diagnosis here is what I have learned and know to be true.
You have soft bricked your phone. For this phone it results in the boot loop you described. At present a Custom Recovery that works is not available for this phone and any attempt to flash an existing one results in a soft brick. There are apps that will flash a Custom Recovery while the phone is one but once you reboot ... !!! Bricked!! This is because ...
a) the memory mapping for this phone is different that other OT-5020 models, so the Custom Recovery placement and indexing is wrong when flashed, causing the boot-loop, and inability for Custom Recovery to load,
and ,
b) the bootloader is locked for the 5020T (different story for other OT 5020 models), and no one has found a way around it yet. Trying to flash back stock firmware for the OT-5020T requires it to be unlocked.
One Touch Update 2.8.0 doesn't seem to want to work one the phone has been altered in this way. SPtools won't work because you need an accurate OT-5020T scatter file (memory map) ,and certification file (bootloader unlocker) to flash any image. In addition to all this the phone doesn't maintain a steady usb connection long enough to allow use of android tools adb and fastboot commands although it does can stay connected in a different mode.
What I have used to restore my phones firmware is a package from Furious Gold that allows the phone to be flashed to factory firmware. I have used it successfully, so I can confirm that the phone wasn't a permanent brick.

hi XDA community i have a problem regarding my a850 and i hope u or anybody can reply this comment in an instance cuz im in emergency...
IM EXPLAINING MY PROBLEM VERY DETAILED SO IT'S GONNA BE VERY LONG COMPOSITION, INCLUDING FROM IM ROOTING THE PHONE UNTIL I TYPED THIS COMPOSITION
so recently i "Framarooted" my device and was working properly as i expected,then i want to install TWRP, i see my baseband version does not have ROW or CN in there, it kinda like "A850.V13 ...(cant remember)", but i flashed anyway using the ROW version of TWRP and Mobileuncle MTK Tools. When I want to enter recovery (via MTK Tools) it doesnt show up, just stuck at white,big "Lenovo" logo (it probably doesnt work) but i was able to boot back to normal. Then i used System App Remover from Play and attempted to delete some chinese apps, and I DID a mistake... i was so clumsy enough to delete all chinese apps that origins from the rom i accidently deleted the file "classical" (which i guess the entire system ui, launcher etc) . Upon after deletion of that file I SHOULD HAVE NOT DELETE , it suddenly booted off with the startup sound muted halfway (its like, the boot startup sound have like 4 second duration and i heard the sound just for 1 sec).
Then it boots up again, but stuck at the logo "Lenovo For Those Who Do" after startup animation, so i assume this is bootloop or soft brick
Realising this incident i GOOGLED " a850 bootloop","a850 unbrick","a850 stock rom","a850 emergency reset" and "a850 emergency backup", then I found a website which describes how to flash stock rom to a850, so i did that, as it might work, but actually not for my case. I followed and downloaded exactly steps and files from that website and loaded Flashtool with its scatter file, then ticked PRELOAD and selected the preload.img, followed by checking USB mode ,clicking "Forced High Speed", checked the DA DL thingy, clicked Firmware Upgrade and the progress bar moved, after that i plugged my phone, without battery, to the pc via usb. I heard the hardware insert sound, but, Flashtool did not start flashing, it;'s still SEARCHING.
Then I read that u need the USB drivers, so I assume i do not have drivers for this phone. I used the Device Manager step and when I plug my phone, it pops up "MT65xx Preloader"(or MTK i dont remember) then I quickly rightclick and "Update Driver". It has two selections, ONLINE or BROWSE, so i clicked the online solution, but Windows seems cant find the driver i need,
so i used BROWSE option, which i used your usb driver by entering the directory of the driver in your file in "C:\Users\User\Downloads\Compressed\Lenovo_Drivers_SP_Flash_Tool_v3.1316.0.150\Drivers" clicked install then it pops up an error "The third party INF does not contain digital signature information", so it doesnt install. So I used USBDeview and plugged my phone again without battery, it pops up "MT65xx Preloaded" with a purple dot, and if you need, i rightclicked that purple dot and clicked PROPERTIES, and here's information it gave:
Device Name: MT65xx Preloader

After checked, i resorted to HARD RESET via recovery (i tried to go to recovery again to see there's hope in there) and it BOOTED TO RECOVERY! (yay) but again problem strikes, the recovery I see now is FULLY CHINESE i dont understand even a single option i gave there.
So now my phone condition is still cant boot to launcher, and my very last resort is to use the JTAG option
pls help me u all and pls reply ASAP
thank you

You should log in to windows with out drivers verification in order to install the drivers. Tutorial on how to do than on windows 8 here. Then flashtool should regognize the phone... (you should fix this problem because you may also need it in the future)
There is also a way to fix your phone (if the classic theme is the problem) using ADB. Go to this page and scroll down to ADB method(tutorial) in order to install the classic.apk as a system apk through ADB.
(i am attaching you the apk: View attachment Theme_classic.apk)
Very thanks though cuz this actually solves my problem on my previous devices which doesn't detect upon connection, but I've actually resorted
to do unsoftbrick by a more professional person in my town (he sells and services phones) and it charged me RM50 ($15). Now my phone is back to normal with a rooted state (Chinese superuser app)
Again thanks for replying.
PS:also can somebody redirect me to lenovo a850 modding page? anybody

Tried Installing a custom rom using Flashtool. Now the phone can't come and can't be dected by my pc. Installed the Drivers and they Installed. At first first I was having a Brom Error report Now nothing happens when I p,lug the phone.
Hi, i have this wonderfull phone (jk) which has encountered a problem with failed encryption, i don't know how. It tells me to reset phone but nothing works, wipe data+ wipe cache.
I've google the problem but little to now answers about this phone, just a thing on the official website but i've discovered that my micro usb has some problems too, and the software provided by utok is working only like that (tryed 3 cables same effect).
I can't find a rom to flash it with stock recovery so i'm stuck here trying to pack somehow the unpacked version which i have here : LINK
or can i find a compatible one for MediaTek 6572 ?

Greetings and welcome to asssit. There is very little information on your device and not 100% certain what you are trying to do. I can link you some tools that will unpack an .img file but can you not use adb/fast boot to reset the phone ?

//edit: i've tryed but can't connect my phone to computer succefully, all diferent drivers and tips, i think it has a problem with microusb. On the official website it says that phoe must be turned off and battery removed, then connect it to pc. When i do this it connecting then lose it then again and again. When i connect it started it remains connected but unkow to the Device manager.
Sry bad english, the verbs kills me.
