[Galaxy S 4 Q&A, Help & Troubleshooting] d3v1c3:
Hi all,

Phone Details:

Spring Galaxy S4

Baseband Version L720TVPUBNG5

Used CF autoroot

This all started a few days ago. The latest OTA update came out and my phone kept telling me I had insufficient storage for the update. I figured it was because I had it rooted. I followed QBking77's video for Unroot / Unbrick. Downloaded all files recommended in the video.

Every time I try to flash with ODIN I get a failure. I have tried three different .tar versions at this point, it always seems to fail after "aboot" attempts to flash. Two different cables, both came with an SGS4.

I finally had enough and used the factory reset. After factory reset I used KIES for my update. The phone took it fine and rebooted. Although now I have no WIFI.

When initiating WIFI it will tell me that the security application has rejected a request to protect my phone. I deleted lookout security even though I have never used it.

Does this have something to do with KNOX? Knox flag is at 0x1 so I know it is tripped. Is there a way to completely flash my phone back to a stock state with the original recovery and rom?

Are there any options for me to get my phone back in order. I really dont give a **** about root or roms, I just need my WIFI. Would my best bet be to use a custom firmware?

[Sony Xperia Z Ultra] mailme45:
First the basics. I'm running CM 11 M12 snapshot, and I've already installed Viper4Android, and it works. I'm aware of the mixer_paths.xml modifications as well, and those work for me. Is there any known setting in that particular file, or perhaps another known config that can be edited that will increase the Bluetooth volume? Viper4Android has successfully increased this, but just by a little. I would like to push it higher. I'm looking for the kind of jump I heard after changing the speaker level in mixer_paths.xml, which was dramatic. I need the extra push because the bluetooth input on my car radio is tied into an ipod adapter that just comes in at lower volume level than other inputs, and to get satisfactory levels with the iPod, I push my volume to about 3/4 of maximum, with the bluetooth I can't even reach that at 100%, and if I switch inputs without changing, it's jarring and dangerous. Thanks ahead of time for any input. I'm trying desperately to rid myself of iTunes and save myself from constantly burning disks.

Hello everyone on the XDA community.

This is my first post here ..!

To begin excuse my very bad English, I used a translator to do this. Second, moderators apologies if it is not the right place, I ask a little patience and if you need to edit or move the topic, are in every right to do so.

Thanks in advance.

WARNING: This method has been tested by me, but do not hold me responsible for lost data on their devices or if they suffer irreparable damage. The method should be used with caution, following the steps explained below and must possess knowledge of the use of the tools used. USE AT YOUR OWN RISK.

Tools to be used:

BLU Phone Drivers

Universal ADB Drivers

SP Flash Tools v5.1436.00.000

Studio C D536U V08 5.0 Generic Stock Rom

Kingo Root

Easy Magic TWRP Installer for MediaTek

The first step and most important is: BACKUP, support all device data if possible make a backup of the complete ROM Stock, since in case of a "sudden death" can use this to revive the device. In the XDA Developers forums are methods to do this kind of support.

Steps that I have followed for an update ROM Stock, rooting and subsequent installation of custom recovery:

If you have any drivers installed for your BLU device uninstall them before seeing step 2.

Install the device driver for BLU

ADB drivers installed Universal

Enable USB debugging on development options

Download and install the ROM Stock mentioned above using the following::

Open SP Flash Tool.

Click scatter-loading then select the scatter file inside the ROM you downloaded (must be unzipped of course).

Change "Download" to "Firmware upgrade" (under scatter-loading file).

Click in "Download" button.

Take battery out of your phone and insert it again. make sure your phone does not turn on (If phone has an internal battery then just make sure the phone is off).

Plug in your phone to your PC.

The green check mark means you're good to go.

After installing the new ROM Stock, or if you were already using that version of the ROM Stock must install the Kingo Root, then connect your device and the program will recognize it immediately. The whole process is very simple and takes very little time, stay tuned to the screen of your device for confirmations.

Already having installed and running ROM Stock and rooting and undamaged device, run the program TWRP Setup, this will create the MTK-TWRP folder on your desktop, in it we find the TWRP.exe program which execute and follow the steps described in THIS POST.

And with that we have our rooting device with a new version of ROM Stock and custom recovery.

FINAL NOTE: In my case after installing the new version of ROM Stock did a search for update from the device, and found a new version: BLU_D536U_V10_GENERIC. The downloaded and installed before proceeding with the routing and the installation of custom recovery.

I hope you can use this guide and is very useful for everyone.

Best regards.

Thanks for the guide, but the rom Studio C D536U V08 5.0 Generic Stock Rom in the mega link, is not available, can you upload?
[Blu Studio 5] alakentu:
Hi.

The following directory on the website of Mega contains all the Stock ROM for BLU devices, look inside the folder named "STUDIO SERIES" the "STUDIO 5 C - D536" folder, there you can download the ROM Stock V8 Generic.

I have a bricked BLU Studio 5.0 C D536L. Can I flash this rom and files?

I don't know if D536U and D536L are the same devices (maybe L and U only a local id).
[Blu Studio 5] vampirefo:
I just got this phone from Walmart, even though I didn't use your method to root, as my rom is newer than the rom you provide, mine rom is BLU_D536U_V11_GENERIC seemed pointless to downgrade, I did download your Studio C D536U V08 5.0 Generic Stock Rom as it contained a file I needed to manually root my device.

I use Linux not windows, so the splash tool doesn't help, none the less I was able to root without any problems, using the one file from Studio C D536U V08 5.0 Generic Stock Rom.

Thanks

Need a pointer or two.

Hello. I have the same phone and conundrum. Sure would appreciate any pointers you could throw my way about successfully rooting this critter. It's a BLU Studio 5.0 Ce D536 Unlocked Dual SIM 5.0 Phone Android KitKat CellPhone.

There was a sale on ebay selling this new for 68.00 so I bit the bullet and bought it. Sure would appreciate it. I use both Linux and windows so I can relate. Any pointers would be great,Thanks!
[Blu Studio 5] vampirefo:
Your device is different than mine, I don't know anything about your phone.
[Blu Studio 5] vampirefo:
Post 3 seems to have files for your phone, should be able to use those files to root your device.

I had to build a custom recovery for my device, I built Carliv 3.3 recovery and TWRP 2.6.8.0 for my device.

Brick/Loop in Recovery.

Hey alakentu, thanks for this great thread. I have a problem at the moment: My, Studio BLU Studio 5.0 C (D536U), boots into the recovery and that is all. If I select Factory Mode it gets stuck on the BLU boot animation. I need to flash a new ROM through the original recovery and I need help with this. Can somebody help me ?
[Blu Studio 5] adnj:
I'll give it a try

I have a 5.0C that has one SIM disabled. The SIM was filled with a platic blank that was glued down. I plan on backing up the custom Digicel ROM (D526 I think) and try to load the D536U stock ROM. I assume that if the hardware isn't customized, the stock ROM will have the code that enables and controls the two SIMS. :fingers-crossed:
[Blu Studio 5] adnj:
I rooted and updated my previously locked phone to the V11 generic ROM. The generic ROM:

1. enabled the SIM that was blocked from the OEM.

2. unlocked both SIM slots.

The upgrade was well worth the trouble that I had with properly loading the USB drivers on my Windows 8 PC.
[Blu Studio 5] jmvaught:
Same exact quandary here as [MENTION=6812435]blackvitriol[/MENTION]. My d536u (Studio 5.0 C) sticks at the Blu splash screen. Is there an RUU mode of sorts with this device? If so, how do I access it without being able to fully boot this device?
[Blu Studio 5] jmvaught:
SOLVED!! (Not that this is an active thread or anything)

So, in ALL of my research I didn't find one single instruction to fix the bootloop, corrupted ROM issue I had. Many claimed to be able to fix this issue, but all fell short because of ONE SINGLE error in the command line. I know, that's all it takes, BUT it may be difficult to figure out (as it was for me). This is all assuming you have your drivers installed and at the very least Minimal ADB/Fastboot functioning.

1. download the factory image (zip, rar, whatever) and UNPACK it somewhere you can easily find in Windows.

2. place the boot.img and system.img files in the same folder as adb.exe and fastboot.exe

3. put your device in Fastboot by doing the following:

a. press and hold Vol Up AND Power until you see the LCD flicker dark (you'll know it when it happens about 3 seconds into holding. Nothing else will happen yet. Nothing will appear on your LCD.)

b. press Vol Up twice and then Vol Down

*you should see three lines pop up in white text on your screen and it should show Fastboot beneath that. If not, pop that battery out and start over. It may take practice to get it right.

4. open a command window in your adb/fastboot folder.

5. Type the following:

fastboot devices

(your device should show up after you hit enter)<---don't type this

fastboot flash boot boot.img

(you should get some action on your device showing it flashed OK as well as in your command window)<---or this

fastboot flash /system system.img

(you should see it working on your device's LCD counting up from 0% to 100%)<---or this

fastboot reboot

(now wait and watch your device come back to life)<---or this

So what's different here from the other instructions out there? You're flashing the system partition by typing "/system system.img" instead of "system system.img"

Any questions, feel free to ask. Have a good one and good luck.

[Blu Studio 5] vampirefo:
I downloaded update.zip and modified it to work with my twrp recovery, I done away with stock recovery, so needed to modify update.zip to work with twrp recovery.

No real improvements that I have noticed, it's an update so might as well update.

D536U is a non American v. And D536L is USA v., mostly.

While both are 2100 MHz, the U generally has 1700 MHz, whereas the L has 1900 MHz.

Theroretically, T-Mobile Homeless Corp doesn't Support 1700 MHz anywhere in the world. Plz refer to device specicfications Dot com or GSM arena site for specs before buying.

Also, the candybar (mobo) is available on Amazon for $10 USD.

[Blu Studio 5] vampirefo:
You got it backwards, The U is USA, the L is not. All the blu phones I buy end in U cause I live in WV, USA.

My new phone is E030U. Do you see the U not L, yep there is a E030L also but sold outside of USA.
[Blu Studio 5] Steve Eligoyo:
Vampire veep:

Perhaps. On the other hand, U is 1700 MHz (which tmo doesn't support), and L is 1900 MHz, (which tmo utilises in Useless A).

Thus, a dual sim L is north American setup.

I invite you to scope device specifications site or GSM Arena site., for frequencies, etc.

Question:

When buying a new mobo for Blu, will I need to flash in the ROM, or is it preinstalled ?
[Blu Studio 5] vampirefo:
Why would I need to search for anything the sim card clearly shows 1900 is working on my devices while 2100 isn't. Now if I had L 2100 would be working while 1900 isn't.

I just noticed you are completely confused, might want to lay down for a bit, 1900 and 1700 are both USA, which is U. L is 2100 with an L phone in USA only 2G and below is available, to get 3G and up in USA one needs a blu that ends in U.

Now outside of USA use L this will allow 3G and up on 2100.

Hey andj this is aannddj i have that same problem but mine is a bmobile d526u cud u plz give me precise details on how to u did it cause i wud like to fix mine too
[Blu Studio 5] adnj:
You can follow the directions given in the OP. You will need the stock ROM fror a d526u though. The custom ROM from bmobile cripples the dual sim and locks the phone. On my three d536u phones the sim was enabled and the phone was unlocked by installing the stock ROM. Afterward pull off the tamper label and empty the slot gently. all the hardware was intact for me.

Stock Studio Rom

Hi. I have a Blu Studio G. Which is rooted, running stock ROM. However today my son was playing on the phone, and went to OTA update and performed it. Now, the phone continuously starts in Android system recovery, and will not go beyond this. The links for mega which you had are no longer valid. Does anyone have stock ROM for blu d790 v17 generic or any advice on what I can do? I don't care what it is, as long as I can get the phone started beyond what it's doing now I'll be content. Please and thanks.

[Blu Studio 5] mexguytj:
i dont think this is going to have an custom rom [MENTION=1074591]Londrina[/MENTION]
[Blu Studio 5] CVAngelo:
What do you mean you tested with different ROMs? You are running custom ROMs? If not, there's only one stock ROM for your phone. Or do you mean different versions of the stock ROM?

Anyway, it could be hardware. This can be caused by a defective SD card or defective LCD. So first thing you want do is remove SD card and see if the phone runs normally. Of course, changing the LCD can be expensive. So before you do that, you really should see if there's a software issue. For example, you may need to clear the dalvik cache (but for that your phone must be rooted). If you can stand to do it, do a factory reset and see if that solve the issue. Finally, make sure you are running the most recent version of the system (go to Settings > About Phone > System Update).

And I just noticed that all of my recommendations are in reverse order. You really should start with the last thing I told you to do, and go backwards from there because this issue is usually caused by software. LOL

[MENTION=7805659]zombie_ryushu[/MENTION] Its confirmed by BLU that will not be an update to lollipop for this phone, a custom ROM does not exits (yet) and to be honest i dont think anybody is interesting in making a custom ROM for this phone (cant do much with it).

hello.. i need help .. i flash rom v08 on my Blu 536u i follow all steps and the install is perfect. but not work.. freeze in the blu logo screen .. what i can do ? thank
[Blu Studio 5] CVAngelo:
How did you do the flash? Flash again and send me a screen shot while the flash is in progress. I would like to see what is on your SPFT screen.

After the flash is completed, do NOT turn your phone on. Instead boot into recovery and do a factory reset. Then turn your phone on.
[Blu Studio 5] shadownns:
i do again the flash .. Not turned on my phone.. booted in recovery and do a factory reset then turn on the phone but dont work .. any solution ?

here two picture. when flash everthing see good .. green splash

NOTE: i do a memory test on the flash tool and show me this message "ERROR: NAND Flash was not detected!" is normal ?
[Blu Studio 5] CVAngelo:
NAND flash error is normal because your phone uses EMMC flash memory.

There could be a different kind of problem. Let me ask three questions:

1. Remove the battery from your phone. What is the exact model number written inside the battery compartment?

2. Where did you get the ROM that you are flashing to your phone?

3. Let's start from the beginning. WHY were you flashing your phone? What was the original problem that you were trying to solve?
[Blu Studio 5] zombie_ryushu:
Has there been any Rom after V14?

Has there been any Rom after V14? I disabled ADUPS and removed it from my System Image due to the ADUPS scare ages back. My device is still on V11. I never applied the V14 Update. I have a V05, V08, and V11 Image Dump from My Device. I held off on V14 because it installed more apps and a certificate CA in the System Partition.

D536u bootloop after all :(

Hi, my d536u got a bootloop sometime ago, then i tryed to fix it witha flash on SPFT, even the green window appear saying OK but the phone didn't boot. does anyoby know how to fix this? very thank you!!
[Blu Studio 5] CVAngelo:
You provided zero information. How are we supposed to fix it???

*What EXACTLY do you mean when you say, "the phone didn't boot?" You mean that the screen stays black and you don't see anything when you press the power button?

*Is your phone still recognized by the computer when you connect it via USB cable? Do you hear the "ding" sound?

*Does your phone's charge light come on when the phone is connected to a power source? Do you see the battery icon when you connect to a power source?

*Can you boot to recovery?

*What EXACTLY did you flash to your phone? Where did you get the firmware from?

*Can you take a screen shot of the SPFT screen showing which partitions you flashed?

*Did you flash using the Download option, or the Firmware Upgrade option?

*Did you flash the preloader partition, or did you uncheck it if you used Download?

*What version of SPFT did you use?

Answer all these questions and I will tell you what is the problem, and how to fix it if it is fixable.
[Blu Studio 5] eduardvi995:
Well, first, thanks for answer me.

I made a short question cause i didnt know if someone would answer me. Im really sorry if you got mad for that men :(

1. when i mean "the phone doesnt boot" means that it stays on the Blu Products Logo. it turns on.i got the firmware from needrom. i downloaded from there twice (i thought the first one was corrupt, but didnt work)

2. yes, the pc recognize the phone (SPFT does) even in fastboot mode. (i have flashed some images )

3. when i charge the phone to a power source, a battery with a lighting inside of it got appear

4. yes, i can boot to recovery, fastboot and factory mode.

5. about the partitions, i flashed all like the previous guy that uploaded those two pictures, but if u really request it, i can upload my pictures.

6. i flashed using both, looking for results, but no success... i even tried doing format and flash, but same end.

7. i never uncheck that or any opcion, i were afraid to lose anything else.

8. v5.1628 and olders

9.thank you for take some of your time to answer me, i thought nobody would do it... :laugh:

P.D : the phone is, indeed, OK, the only thing is that it doesnt pass bootanimation, doing whatever i do.
[Blu Studio 5] CVAngelo:
Not mad, bro. Lol. Just trying to understand the problem.

So, it sounds like you may have the right firmware. In that case, boot into recovery and then do a factory reset. Do it twice. Then reboot the system. Wait 10-15 minutes before assuming that it's stuck.

If it's still stuck on the boot image, try flashing a custom recovery for your device (you'll need to do a Google search). Then boot recovery and clear the Dalvik cache. Then try to reboot.
