Hello to all.
I bought recently a Tengda T94 (also being referred to as Dapeng T94).It has MTK6589 chip.
Me,the smartass,wanted to change the DPI setting of the smartphone,because Real Racing 3 lagged a little bit and thought changing it might fix the framerate.I changed it from 320 dpi to 221 with LCD modder and reboot.Then the surprise struck me,when it didnt start,it just stood on the logo and kept replaying it.I have tried with ADB commands - some works,some not.
I am with stock recovery 3e.
Has only few commands like reboot now,install update from adb,cache,sd card and wiping cache and another option for wiping data to factory settings (and two irrelevant options of restoring/backing up user data).
I tried wiping all data and cache,still bootlooping.
Tried with mediatek firmware adapter tool,but i think it cannot change the build.prop file while bootlooping (it cannot find my device when in recovery mode),because it is either in use,or in read-only mode.
Tried with android commander,but didnt know what to do there.
I downloaded rather late a CWM recovery for my phone,and also if I am not mistaken two roms - one of them is exactly like mine.
But when tried to install thru recovery adb sideload it starts and then says : restating ADBD ....... installation aborted and returns me to main recovery menu. Tried with my backed up build.prop which i have put in flashable zip file.
However,the two roms i have downloaded arent working properly.They are zip,but still adb sideload cannot read them.
And another (i dont know if it is relevant) my external sd card 16 gb default,when i put it in my old gsm to put the two roms and cwm recovery files,first windows wanted to format it and the only option was FAT 32,total of 2.87GB.What has happened to my sd card ?
Still I couldnt install from the external sd card the roms,only zip with build.prop file was listed and gave the same mistake as said above : restating ADBD ....... installation aborted.
PP: I have arrived at the conclusion that the problem is this line ro.sf.lcd_density=221,which is in build.prop file (I might be wrong).So the question is can i somehow modify the prop file or what should i do ?
And why has my sd card shortened from 14,6gb to 2.87 ?
Sorry for the long post.
Problem with T94 too
I tried to modify the build.prop file to enable the soft keys and the phone doesn't work now! stops at the android logo and I don't know how to make it work now. I re-edited the file back to its original using ADB explorers and still the same. Any help on how to recover it would be highly appreciated.

if you want the original build.prop file i have got it,
can you tell me how did you do the CWM recovery without the phone being working?
Installing CWM Recovery Tengda T94
My phone has been bricked and after really hard work I could install CWM Recovery and I'm about to try the Spanish rom, so wanted to share what I have reached to before I forget.
----Do at you own risk-----
-My phone was in a boot loop and USB debugging was previously activated before it bricked
-I installed all the necessary drivers, USB_VCOM_Drivers (Available here: http://goo.im/devs/C3C0/THLW8/tools/USB_VCOM_drivers.zip)
I created the scatter file/map using MTK droid tool, and used the CWM Recovery of the Spanish Rom at this link:
http://www.movilesdualsim.com/foro/threads/42700-ROM-Custom-ROM-T94-v1-0b
I'm going to upload the scatter file and the CWMrecoveryT94.img, download this sp flash tool for quad core scatter files
http://www.4shared.com/zip/kf__h7u-/sp_flash_tool_zopomobileshop_q.html?cau2=403tNull
Switch off your phone, open SP Flash Tool Quad Core that you downloaded, choose the scatter file available here, double click recovery and choose the CWMrecoveryT94.img available here and press "Download" press yes for the message that appears and connect your phone, it will confirm the success by a green big circle message.
I will update my further proceeding.
Tengda T94 GPS never works
Does anyone have any idea about fixing the GPS problem? I watched a video in youtube in spanish who showed a working fast GPS but I don't understand what he says but he showed in the description that he added a copper foil piece to the GPS antenna, if anyone had luck fixing it please share.
Here is the video:

Hi folks,
unfortunately I somehow bricked my ZTE Open. I flashed cwm (worked fine) but after flashing both system AND userdata via flash_image, the phone won't boot and what is much worse it won't boot into cwm anymore as it hangs there with just showing the logo and the cwm version. The menus are missing, it does not react buttons and does not show up in adb. FTM mode is also non-functional, holding volup gets you also into broken recovery.
For earlier ZTE devices like the ZTE Blade it seems to be possible to low level flash them in diagnostics mode. Diagnostics mode is working fine on the ZTE Open (it shows up with the diagnostics port on USB. Luckily I also have all the 20 partitions backed up, but I don't know how to flash them in this diagnostics mode. I tried putting the files into the root of the SD card and including sha1/256/512 plus md5sum files, but it was not impressed by that. Not sure if this only works in FTM mode, though.
Any help would be highly appreciated! I highly assume that the procedure is the same as for the ZTE Blade.
This may help. http://pof.eslack.org/2013/07/05/zte-open-firefoxos-phone-root-and-first-impressions/
At least there is more going on for Firefox Open over there.
Thanks but as you might have noticed I posted several comments there already, but I thought XDA would be the right place for unbricking devices.

Sorry! Eyes tight shut!
Are there any updates on this one?
I have bricked Open too, I'm attaching the PCB picture, if it is any help to maybe find UART or JTAG pins?
Can someone be really nice and please dump the bootloader from working ZTE Open in send it to me?
I've found some guy, who maybe can help me write bootloder with JTAG.
I think this should work, but no promises: https://sites.google.com/site/zteopenfirmware/download-mode

Thanks for your time to help, but this does not work for me. I get an error, when I press flash button (printscreen under attachments).
I've tried to probe the pins with the multi-meter and found GND and V+ (picture under attachment)
Now it would be nice to have something like this -> http://www.grandideastudio.com/portfolio/jtagulator/

tpt files for the zte open
https://www.dropbox.com/sh/rnj3rja7gd54s98/_twgXEkMFH/P752D04_DEV_EU_20131212_v1.2.7z
Thank you for the link. But what tool is supposed to be used to flash the files? And is there a way I can use my backup as well? In this case: how can I transform it to TPT files?
Update: I tried flashing it by following the instructions of the link posted by psywolf, but unfortunately I am getting the same error as aversario. I tried also flashing just recovery, but it seems like no single partition is flashed successfully.
So, I've ordered jtagulator and it showed the pins. Now I need jtag programmer, which one do you guys recommend?
And I am still looking for some great guy to share with me his bootloader of a functional zte open.

Well, I don't know the partition names by heart, but as I remember the bootloader is one of the small partitions (so definitely not system or boot or userdata or recovery).
The way to get that small partitions would be installing CWM recovery first -> http://pof.eslack.org/2013/07/05/zte-open-firefoxos-phone-root-and-first-impressions/
then enter adb shell on computer
su # to get root privileges
then it should be something like explained here -> https://www.youtube.com/watch?v=j3GOzUURSgM&feature=player_detailpage#t=153
And thank you very much for your time
If i figure out how to do that without CWM i'll upload it for you. Cannot install CWM because i need to be on stock recovery for development of update packages, sorry

OK, I get that. I'm sure there exists a way to do it without changing recovery also. I just can't figure it out because that's the only Firefox OS phone I've had.
try to reinstall
Hi, I bricked my ZTE Open (EU version) too. Had bought it from a German Ebay seller and tried to flash FirefoxOS 2.0 on my device. I don't have the CWM recovery installed, only the "Firefox OS System Recovery" Big mistake, I know . When I switch on the device, the Firefox OS logo appears, then disappeas after a few seconds, and so on, the perfect bootloop
I can't access the device via ADB or fastboot.
When I ty to install any downloaded zip (even from ZTE's homepage) from the SD card, I get following messages:
Code:
--Install /sdcard ...
Finding update package ...
Opening update package ...
Verifying update package ...
E: signature verification failed
Installation aborted.
So there is no valid signature.
Can you help me please? Thank you!

Found a solution by myself!:victory:
I downloaded the update.zip file from firefox.ztems.com (Update package of Android GB for OPEN device) and installed it.
After that I could flash the CWM recovery. It seems to work...
After a successful root I probably made mistake in editing "vold.fstab" (I want to change the sdcard1 for sdcard2) a tablet hangs when loading ( still spinning wheel and the system will not boot ) .
I download a recovery file by "nandroid" from some Czech Republic Android forum, put in on SD card but in CWM I'm still see that "restore not found". So I can not restore with this file.
Could someone help me?
Somebody said that update firmware can help, I have officialy firmware update in format img . PMP5101C_20131019_v1.0.8.img , but do the update through the program what official makes Prestigio requires the tablet is on (boot in system), which unfortunately is not possible .
Maybe it is possible to do it with RKAndroidTool, there can be tablet off (just turf off, push volume+ and connect cable) . But I dont know, what is the numbers in box " Address" for firmware update ((
Alternatively, maybe somebody can create a update.zip file for me, that I can use in the CWM and make a update with this and overwrite the "vold.fstab" to the original.
If someone help , I also like to reward for PayPal.
I do not want have a tablet for 200 EUR as a paperweight.
Sorry for my poooor english.

Do you have the files to root this device as i have CMW 6.03 installed, but when i use the SuperSU-v1.65.zip that came with it, it errors.
Please help as this is a great device from Maplins at a great price.
@dvd73
Not sure if you managed to fix your problem.
I messed up my framework-res.apk trying to get usb tether enabled and my 5101C also did not boot.
I reflashed my rom to v.1.0.11 from the official website according the instructions provided and it was like new.
No need to start it up, you only need to get to flash mode by holding vol+ while pluging in the usb, then RKbatchtool will recognize your tablet.
@happy2help
Try updating your rom to v.1.0.11 and then flashing the CWM recovery. Then download the latest SuperSU zip from xda and install the zip, this worked for me.

Hi, I just bought this phone from TECA Mobility, it turns out to be an Alps S5. See attachement for a detailed description.
I tried to ge the root. I tried some different tools, without success.
MTK Droid Tools ROOT button doesn't work but gives a link to xda's MKT forum, so I started with the recommended procedure. I tried to read back the ROM with SP-FlashTools but no way, it doesn't start. I also made some attempts with the Android SDK but adb backup of course doesn't work for the System partition without root.
When I send the adb reboot recovery command the phone goes in download mode, with the adb reboot bootloader command it goes in fastboot mode, while to have it in the factory recovery mode I have to manually hold down the start and vol down buttons. However, it doesn't matter, the readback does not start.
Should I try to install the CWD recovery without having a backup of the ROM? I think it's too risky. I looked at NEEDROM to see if I can find my ROM, but didn't find. I found these, "S5 SM-G900 MT6592", but I cannot be sure it's the right one.
Somebody can help me? I want to root the device.

Hi
1) First root your device using MTK Chopper (from PC) or framaroot (from android app) . Both work fine for MTK phones
2) Then using MTK droid tools backup your ROM. Here is the guide for that
http://forum.xda-developers.com/showthread.php?t=2730031
3)Then using MTK droid tools , make CWM recovery for your phone and install it . Here is guide for that

I think you mean MOTO Chopper? It doesn't work, same as framaroot. They are old tools, they don't work anymore on the ROMs released after June 2014.
ODIN could work but I have not the sure/right file to download.
Generally speaking, the first thing to do is that of getting a backup of the ROM from the un-rooted phone
The guides that have been reported to work in these cases are:
From XDA:
http://forum.xda-developers.com/showpost.php?p=38337401&postcount=5
From China Devices:
http://www.china-devices.com/Thread-ROOT-CWM-Readback-your-ROM-with-SP-Flash-Tools#
Hereunder is the link to a success case story:
http://www.china-devices.com/Thread-Rooting-new-octacore-S5
There is no way I know to get the root with one-click-tools, there is no case I could find of anybody being able to root these phones by following other procedures.
If anybody knows better, please send me a link (MTK phones with ROM s released after june 2014 only!!!)
My only problem now is that I cannot get the read back with Flash Tools. I have tried uncountable button-pressing combinations, I have put the phone in recovery, download, fastboot mode, I have tried with and without battery, phone switched off or on - no error, but the read-back doesn't start (however my phone doesn't have the USB connection working when it's off or without battery).
The only way to skip this step is, if I had already a copy of the firmware available, a sure one.
Kindly help me if you can

As bizarre as this sounds, I managed to get root on a similar phone (another MTK6592 S5 knockoff) with MTK tools. After exhausting my options, I clicked the ADB button and tried to get root shell regardless (via 'adb root shell', which probably isn't the proper command but it works regardless), which caused some sort of hang. After a minute or so I unplugged my phone, which caused things to start responding again; plugging it back in showed me as having temporary root, and the get root button actually worked the next time I tried it. I have no idea how or why it worked, or if it was a once in a lifetime occurrence, but it can't hurt to try.
Also, if your phone is anything like mine (and is actually running some form of KitKat), good luck getting write support for external SD cards. I couldn't get the system partition to mount (to write changes to the necessary file) via anything but ADB shell.
Problem solved
Good to know, thank ypu.
However in the meantime I solved my problem.
My phone works this way: I have to remove the battery and connect it to the USB cable. Then it goes in "preloader mode" and tries to install a driver called "MT65XX preloader driver". This driver actually emulates a COM port. If data transfer doesn't start, then, after a few seconds, the device goes down and disappear from Windows list. So it is easy to miss it when we install all drivers. I had to dowload it (from Google cloud service in my case), install and ... the Read Back started !!! Now I have completed the procedure and my phone is rooted with the CWD recovery installed.

Maybe your phone was using firmware dated before june 2014? These was a bug that was exploited by Framaroot, but now they fixed it.
Is your phone also from ALPS? They sold it to me as capable of installing an external 64GB SDHC card, but I cannot have it working. Did you face any similar issue?
Otherwise 32GB cards work fine. Have you tried Aparted app? I use it for formatting/maintenace. This app makes partitioning, I guess it should work.
Also, if your phone is from ALPS, does it really have the ROM memory that is advertised?
I am facing some interesting issues with my phone on this respect. It was sold as having 16GB internal ROM, of which about 12GB avalible for users. In fact, the settings menu shows 10GB ,( 8GB available) of internal memory, and about 4GB of phone memory. Well, if I am correct, this so called internal memory maps to the directory /data (the one highest level in the root), who corresponds to partirtion mmcblk0p7. This partition actually has a size of 2.3GB instead of 10 !!!. f I install and try to run online Nandroid backup, I cannot have it working on paths directed towards the SDcards, but it works on the path data/media. Well, a backup of about 1.2GB is shown in the setting menu of the phone as a memory consumption of about 5 GB !!!
Then I had also hard time in copying this file from the /data directory to one of the SD cards. Root Browser and Root Explorer didn't work, only ES Manager with root rights worked.
Maybe you can give me some advice in finding some tool or SDK procedure to assess what the real total size of the memory is? Or some suggestion on how to fix the ext 64GB card? I got bad feelings with the guys who sold this phone to me, so I would like to collect some more evidence if possible.
I downloaded some applications for making device inspection. They read the manufacturers' data, so they get cheated - even if, in some cases, they can show the right amount of unused memory still available (quite lower than declared by the phone) . Also I cannot see the real size of the RAM memory used by the CPU .
Need stock ROM for Teca g89 mobile.
Hi experts,
I need stock ROM of TECA G89W ANDROID 4.4 2.4GHz 4GB-RAM +32GB 18MP 5.5-inch GPS SMARTPHONE. I brought this phone 6 months back and unfortunately the software corrupted.

Hi,
after ROM flashing (ROM that was working fine for me earlier - MIUI V5 5.1.30 , Android 4.2.2 )
i started to get this in recovery :
unable to mount /emmc
unable to mount internal memory
unable to mount /data
+ i cant even wipe dalvik cache.
after first boot, the ROM is stuck at boot logo ( MI logo).
I thought its a bad flash so I flashed a ROM that I got the phone from dealer with (MIUI 4.4.25). Phone turned on, but the IMEI numbers are gone.
When I run Mobileuncle tools / Engineer mode , the CDS Information option is greyed out, its not active.
So I wanted to recover the IMEI via MTK Droid Root & Tools . But when I plug in the device to the PC, the PC doesnt recognize it.
Also, my phone doesnt recognize the SD card (in the OS, in the recovery its everything OK).
Can you help me with this?
THANK YOU

I thought its a bad flash so I flashed a ROM that I got the phone from dealer with (MIUI 4.4.25). Phone turned on, but the IMEI numbers are gone.
When I run Mobileuncle tools / Engineer mode , the CDS Information option is greyed out, its not active.
So I wanted to recover the IMEI via MTK Droid Root & Tools . But when I plug in the device to the PC, the PC doesnt recognize it.
Also, my phone doesnt recognize the SD card (in the OS, in the recovery its everything OK).
Can you help me with this?
THANK YOU

flash it back with original firmware using sp flash. dunno with IMEI though if it will come back.. but start from there.. after that root and go to mobileuncle to restore your IMEI.

Hi. What MIUI did you flash ? What version ?
What you have to do is to enter again in recovery with vol+ vol- and power button pressed all together!
Wipe everything except SD Card!
Remove your SD Card and go to some laptop or PC with SD Card reader, copy your old MIUI on it.
After copy and wipe go to your phone and insert your card.
Start your phone directly in recovery and now your SD Card should be recognized by the phone.
Reflash your old MIUI.
Good Luck.
Tell us if you have problems!

i cant. the recovery isnt mounting emmc, data, internal memory.
that will be a big problem if phone cannot be detected on sp flash tool anymore. make sure phone is turned off and the sp flash is waiting for your device after you insert cable to phone.
i made some progress, MTK Droid Root n Tools recognized the phone.
i should be able to flash the stock now, right?
EDIT: I managed to flash S135 (130917) - stock chineese rom and internal storage, USB storage, SD storage - all seems to be functional and loaded. So this issue seems to be figured out.
EDIT: flashed desired MIUI 4.4.25 Multilang via CWM, all storages operational. Im on fixing the IMEI now.
--------------------------------------
EDIT: I cant restore the IMEI.
I tried imei.exe trick. No change.
I tried engineering mode / Uncle tools - in MIUI i dont have access to CDS Information, in stock ROM I do, but experience a "failed to send" response.
I tried MTK Droid Tools - i type in new IMEI, i reboot via the programme and after reboot the IMEIs are still "null"/"null".
Im desperate. Any help?

This is bad... Your NVRAM is erased! Look on /dev/radio/ and tell us if this radio folder is empty!

looks like i need to restore hard-IMEI, this is my case:
NStorm said:
They guy clearly told he is able to restore MP0B_001 in phone, but its SOFT-IMEI and is lost after wipe/factory reset.
@ Original question by ToldarkenHansam, which is kinda outdated, but considering lame answers here:
To restore HARD-IMEI in NVRAM hidden partition use SN Write Tool or Maui META 3G. They are able to write hard IMEI and calibration to NVRAM partition.
@ kokabunga - if you have nvram.bin backup you can easily resore it with SP Flash Tool. Just open your scatter file with any text editor, find a __NODL_NVRAM section and remove __NODL_ part from it. Reopen scatter in SP Flash Tool and you'll be able to check NVRAM partition.
It might not be able to upload it without other parts selected. But you can you Options->Write memory, then manually enter start address, which will be show on download/upgrade page near NVRAM and length (your nvram.bin length) - that will always work. Be careful to write correct address thou.
Sidenote: all suggested methods before only touch SOFT-IMEI, stored in /data/nvram/md/NVRAM/NVD_IMEI/MP0B_001. Its lost with any wipe/reset, because whole /data partition are formatted. Then the whole /data/nvram directory (if it's empty) are restored from hidden NVRAM partition on EMMC. If you've corrupted your NVRAM when it won't restore correct IMEI ofc. With all methods mentioned above (i.e. replacing MP0B_001, echoing to pttycmd1, using mtkdroidtools, mobileuncletools and others) will only edit MP0B_001, i.e. soft copy of IMEI, which will be lost again with next hardware reset. Sure you restore your IMEI that way every time you wipe/reset/upgrade firmware. But its more solid to fix your IMEI partition with SN Write Tool / Maui META 3G so it will be correctly restored automatically from NVRAM at every wipe/etc.

but Maui META 3G isnt recognizing my phone, though it starts a meta mode automatically. SN Write tool itsnt working as well.
Thoughts? Is it possible to flash just a nvram partition? When I try my SP Flash Tools get a 8038 error.
i found a nvram.img for p780 from someones backup on the web, so i tried to restore it via adb, i got this:
edit: OK, the batch file runned succesfully ( its the utility nvram_backup_restore_wo_root-shell_3.7z , stympy, you posted it here in one thread )
what shall i do now? the IMEI are still invalid after reboot.
put the nvram.img to your sdcard not on your computer. and try the batch file again.. I tried that before using that image .. it did not help restoring imei... try it maybe it will help you
Hi all. For those of you who flashed wrong firmware and your IMEI are gone look what happent to me:
1. i flashed a custom recovery who errased my IMEI. That happent because the recovery was 7.5 mb instead of 6 and i was "blind" and careless and stupid and...nevermind
2. after restart surrpriseee.. no IMEI.
3. allmost total panic here.On MTK Droid Tool 2.5.3 IMEI NULL paniC again, and my worst nightmare PTTYCMD1 ERROR FILE NOT FOUND. Panic panic panic, used hard words #@$^%&(&&%$%& words alot.
4. after a little cooling i reflashed my old TWRP back and started to look in my computer for the firmware i allready have installed wass Baralajbi v6 (i like the partitioning of internal memory) firmware from needrom. Before that i tried to restore the NVRAM from TWRP. It did not work. No IMEI has appeared after restoring with TWRP.So i have rebooted the OS back and i immediatly go to /dev/radio where the PTTYCMD1 and the folder was empty.Again *&^%&$%^#^%#%^#^&(*(^* words.
5. Then i have reflashed Baralajbi firmware and after flash i have installed Root Explorer. Again i immediatly go to /dev/radio where the PTTYCMD1 and the folder was this time all the files were there.
6. So if this file PTTYCMD1 is in the /dev/radio folder you can restore your IMEI safely with any tool.
7. I hope this little problem of mine will help you other users to restore your IMEI.
I flashed different recovery (6mb, cwm) and different rom (miui 4.4.25 multilang).
I managed to get this... (But all of them have 0 size). Is it good?
I tried to use mobileuncle tools, but the option i need is still greyed out (wonder if miui blocks it out? on stock rom it was accessable)

You must try to flash a stock firmware CN or ROW.
MIUI is custom firmware.
The firmware must be flashed with SP Flash Tool.

Hello everyone
Well they say you should not mess with thing you do not perfectly know about exactlt same thing happen to me. Well i have Mediatek device MTK6582 running kitkat v4.4.2, i was trying to root it but to no avail.So finally i read a post here about how every phone can b formated by installing CWM/TWRP recovery and then installing the SU binary using custom recovery installed. Ok i followed this method.
1) Made a backup using MTK droid tools of following locations (i still have that backup).
a)PRELOADER
b)MBR
c)EBR1
d)BOOTIMG
e)SEC_RO
f)LOGO
g)EBR2
h)ANDROID
2)Created ROM file.
3)Processed the ROM file for sp flash tool.
4)While processing the ROM file MTK droid tools was unable to make a CWM recovery file.
5)I do not know why but i formatted my recovery partition using sp droid tool.
6)When i tried to put recovery backup to its place sp flash tool would not do that.
So i left my phone as is it for sometime untill i ran out of space and no more apps could be installed.So i decided to format the USRDATA block. This is where things went really bad. I guess in sp flash tools i did not write the correct end, adress i wrote the size of that block it was 0051400000 on MTK droid tools , iguess i should have wrote the starting adress of next block.After format my phone would not start.It was stuck on manufacturer's logo.So on a different PC i downloaded all the stuff i mean drivers sp flash tools MTK droid tools etc. And tried installing my phones recovery, and this time it was installed perfectly.I went into my recovery wiped all user data and phone started normally untill i realised that no network was there and a "No SIM card" notification was there. So i did a factory reset thinking maybe it would help.But again phone was stuck on manufacturer's logo.And this time i would not even enter the recovery (it would show as if it is entering recovery i mean the animation stuff that shows when it enters in the recovery and then the phone would restart and stuck again).So i reinstalled the complete backup of all blocks that i have mentioned above.And phone switched on successfully. But again no "SIM card detected".
So i googled, and in Last 24 hours i tried everything i could find there (alright maybe not everything but most of "everything".And i also have a successfully rooted my phone.
Here are my observations
1) When i connect my phone with MTK droid tools it shows no IMEI.
2) MTK droid tools also shows no baseband.
3) Settings>About phone>Status>IMEI information shows No IMEI for both SIM cards.
4)In factory mode where there are all the tests and stuff shows the actual IMEI's of my device But no SIM card.(Note: No IMEI in settings).
5)In ES file explorer data/nvram shows a lot of files and folders its not empty.
Here is what i have already tried.
1) Tried restoring IMEI using MTK droid tools.
2) Making new MP0B_001 using imei.exe
3)Installing my backup for second time.
Right now i am do not know what to do next.Any help i would gretly appreciate.Sorry for long post when i wanted to clear so that you can suggest something.Thanks
