Ok thank you free_login

To explain to other members

Rom is based on Wiko Rainbow MTK6582 CM12.1 ROM (specifically 12.1-20160105-UNOFFICIAL-Ajit-mtkroms.com, Build date Jan 22 2016 1:48 AM)

Kernel is 3.4.67 rdadmin@vBuild1LT80 #1 (Wed Apr 8 14:37:07 CST 2015)

I wiped whole phone via TWRP (mentioned on 1st page), flashed boot.img (install img into boot partition), and flashed system.img through "adb shell" into TWRP ("dd if=system.img bs=1M of=/dev/block/mmcblk0p6")

After I rebooted into system (twrp warning about missing os installed, you can ignore that), phone booted pretty quickly.

Notes:

- First language of phone is Russian

- Original ROM was binary modified (as confirmed by free_login)

- CM is 12.1

- Multi-SIM capable, however my SIM cards are currently not detected

- KingRoot is preinstalled, and downloaded like 10MB after I booted phone and connected it to WIFI

- What works: WIFI, Camera (also the front camera), Youtube Video (gpu hw acceleration looks ok), Sound, Jack detection (phones plugged in), USB debugging (adb), Display (obviously), phone speaker, microphone, buttons underlight (below the display), volume buttons (the middle one does nothing currently), Flashlight (camera light), GPS (but waiting for the fix was quite long), Bluetooth

- Runs pretty fast

Thanks muchly!

1) Firstly, thank you all contributors for a GREAT resource for the B15Q debugging.

2) Next, we are having trouble connecting the B15Q with ADB. It is recognised in preloader mode and in recovery (using "apply update from ADB" option, for sideload only), but we never managed to make the drivers work for full ADB access. Booting the phone in normal mode results in a driver "MTK65xx Android Phone" with issues, no ADB link (adb devices fails to see the link).

OS: Windows XP SP3

Any thoughts?
[Miscellaneous Android Development] smarek:
Well, I screwed up, I've accidentally formatted whole phone except for preload, is there any whole firmware (specifically sec_ro, logo, ebr1, ebr2, misc, protect_f, protect_s, seccfg, lk) please?

Well, if anybody needs next time, go by this guide, it works: http://xdaforums.com/showpost.php?p=65222935&postcount=56
[Miscellaneous Android Development] Garfae:
Cannot flash PRELOADER -----> solved!

Well, here it's the other way round:

Following the "PMT table changed, need to format" message, the B15Q was formatted (but not before a full backup was taken), however spFlashTool does not recognized the downloaded PRELOADER partition as valid... So can't flash the PRELOADER back to phone.

Any thoughts? Do you maybe have a working PRELOADER accepted by spFlashTool?

EDIT: Turns out that PRELOADER needs trimming........ Here's the original post:

Here's a correct PRELOADER (convenience repost, courtesy of bigal1337) which is recognized by spFlashTool:

Just to let everybory know, I've finally received Kernel sources for B15Q from CatPhones.com, I've not yet verified they match and run correctly on the device, but it's something to start off.

Hello, I'm sorry to wake up an old post. But thanks to this post, I managed to repair my smartphone.

Due to improper handling, I erased the rom. So I managed to reinstall the 1.019.000 rom thanks to you. I just have a problem my GPS does not work anymore. he can not find the satellites anymore. Would you have a solution?

[Miscellaneous Android Development] Doggy77:
Thank you very much.

As far as I understand you need 1.032 Stock ROM installed and flash the boot and the recovery partitions using the image files you provided using sp_flashtool.

After this you can use an SD-Card mounted as internal memory and hence overcome the damn little 1.8GB small memory for apps and so on.

Is this conclusion correct?

Could you please explain briefly how to prepare the SD card? One partition or several partitions? Format as ext4/ext2/fat? Place files from ROM on it or not?

Greets,

Doggy
[Miscellaneous Android Development] fredbzh:

[Miscellaneous Android Development] joerggutgesell:
"Hybrid sd card"

I added a non swap cwm recovery to the download location so you can do the hack and continue using your phone without loosing any data.

Lets' start:

1: Shrink the sd card's fat32 partition using your pc and any partition manager. Using the freed space create a new primary partition with ID 131 (0x83, linux native). You may format it as EXT4, but that will done by the recovery anyway.

2: With the sd card back in your phone flash the non swap cwm recovery.

3: Boot the recovery and do a backup.

4: Now flash the swap boot and swap cwm recovery.

5: Again boot the recovery and restore DATA ONLY (important!)

6: Test your phone. The new created sd card partition should now be your phone's data partition. All your data should be there.

7: Delete the backup as it contains the old boot and recovery. Make a new backup so that you are able to restore your phone at any time.

8: Enjoy your phone's new life time!
[Miscellaneous Android Development] fredbzh:

If you erased the nvram your IMEIs and MAC address should be gone. Check them.

Yes, I'm able to edit settings and my device is not rooted. If you have a corrupt file system write access might be denied. But how to fix?

Did you try a factory reset? Edited settings are written to /data/nvram (can be viewed and edited by a root explorer). A factory reset copies the nvram partition to /data/nvram with (hopefully) untouched original settings.

---------- Post added at 07:38 PM ---------- Previous post was at 07:18 PM ----------

Edit: Maybe I'm wrong and nvram is copied during every boot. Once I tried to edit one imei (in /data/nvram) and it reverted after boot. Setting it to read only made it permanent.
[Miscellaneous Android Development] fredbzh:
I tried the factory reset, without result.

I have reinstalled the 1.19.000 rom via SPFLASHTOOL and I think it was at this moment that I had to make a mistake, I replaced my NVRAN file by the one that was contained in the rom, I will not have to do it. I have no backup of this file.

What's odd is that the 2 imei are ok.

After installing the 1.19 million Rom,

at the start of the phone, he found the official update 1.32.000

After installing the 1.32.000 rom, the GPS still does not work.

Carerpillard does not repair this phone anymore since it is no longer manufactured.

With 4g, MAP software and others work, without 4G, none works.

My NAVIGON software does not work without the GPS chip.

To do some manipulation, I have root mo telephone via KINGROOT.

I can remove the ROOT by uninstalling KINGROOT

I'll wait, I put money aside to buy a new phone. I think to take the name S50 that will be released soon.

Each device has its own unique nvram so I won't give it away and yours seems to be ok. I'm just uploading a partitions' archive. Some of the partitions might contain drivers. Start with expdb, sec_ro and uboot.

And DON'T touch the preloader unless you know what you are doing!

I am anxious to switch to Republic Wireless for the savings - but only if I can root my phone (for apps, not so much custom ROMs.... only because I assume none have the RW software needed for wifi calling).

That said, anyone here root their 2014 moto X on their service... and can you unroot should you have a need to use the phones warranty?
[X 2014 Q&A, Help & Troubleshooting] borxnx:
The only way to root any variant of the Moto X 2014 involves unlocking the bootloader at this time. There is no "unofficial" unlock, you can only do it through Moto's site. Requesting the bootloader unlock code for your individual device through Moto's site voids all warranties. Therefore, any root currently for this phone will void your warranty permanently.

I don't know whether Republic Wireless devices will be unlockable in the first place, currently it's only Pure Edition, US Cellular, and overseas variants.
[X 2014 Q&A, Help & Troubleshooting] aenews:
If you have a custom ROM or modify stock firewalls values with iptables, throttling is nuked, and even the $10 plan will be unlimited LTE. Too bad there's no root. All restrictions are in the software oddly enough. Unfortunately there is no root. Even the last Moto X on the current update has nothing.

[T-Mobile Samsung Galaxy S 4] tailgunner9:
Is it True that Samsung Galaxy phones for T-Mobile do not have Locked Bootloaders??? So if true, I can use a T-Mobile Unlocked Galaxy on AT&T network? But would not get updates for it while AT&T sim card is in it and using AT&T? CORRECT???
[T-Mobile Samsung Galaxy S 4] rlichtefeld:
There are 2 "locks" that you seem to have confused.

1) T-Mobile phones are SIM locked when purchased from T-Mobile. That is they can only use T-Mobile SIMs. Once they are paid for, T-Mobile will give you a code to unlock the SIM lock. You could then use it with AT&T, but their 4G LTE systems are slightly different, so you may not get the same speeds when using the AT&T towers.

2) The T-Mobile S4 SGH-M919 sold does not have a locked bootloader, which means you can root it, and also install custom Recoveries.

There are several threads about using this phone with an AT&T SIM. Google/Search is your friend.

I have an acer a700 and it was stuck on the acer startup screen. I tried an official factory reset using the acer firmware and got the red exclamation android symbol. I managed to unlock the bootloader and install CWM . I decided to try a custom rom and snagged the nightly CM-11 that was in the the suggested Roms thread. It started up I got to the welcome screen and I thought everything was going well except the AOSP keyboard kept crashing. Because the AOSP keyboard kept crashing I decide to try an older version to see if it was a bug, so I went with CM 10.2. I did the standard factory reset in CWM, wiped the cache, and the dalvik cache. On the next reboot It goes through the CM boot screen, then it hangs and reboots. It does this repeatedly. I tried the AOSP rom, and I tried Pacman as well. They all do the same. I tried to go back with the original CM that at least let me boot but now it's doing the same thing as well. CWM works every time and everything else checks out on the tablet. Do you think that it's got a hardware problem?

I want to buy an extended battery for my S2. But I don't know which one should I buy.

What high capacity extended batteries do you recommend?
[Galaxy S II Accessories] Jleoz:
Official or Fake?

If you want an official one, go with Samsung's 2000 Mah.

If you would something else (fake), it could potentially ruin your phone by blowing up or melting.

If you look around, people have done tests with 3000, 3500, 1800, and original 1650 Mah.

The only one that actually lasted longer was the 3500 one.

So if you would like my opinion, either Samsung's official or 3500.

Hope this helps,

Jleoz. :good:
[Galaxy S II Accessories] avorlen:
2000 mAh is not enough for me. I want the highest capacity battery available for S2.

Which 3500 mAh one is the good? I read several reviews, but they are mixed. Some say it's really 3500mAh, and others say it's fake.

So which is the highest capacity extended battery for S2 that is not fake?
[Galaxy S II Accessories] Jleoz:
Its a 50/50 chance. But I don't know any official version of the 3500 mAh battery.
[Galaxy S II Accessories] NoxCivi:
I'd guess, that none above 2000 mAh keep their promises. I got a 4800 mAh battery from mbuynow and it actually has about 3200 mAh (measured with battery monitor pro). This value also seems more realistic, when I look at the size of the battery. As the capacity is based on physics and not magic, a real 4000 mAh battery needs to be twice as large as the 2000 mAh battery from Samsung. So the size is a pretty good indicator for the real maximum capacity. A real 4000 mAh battery should be at least 14 millimeters thick, as my Samsung 2000 mAh (you can't have enough spare batts ;)) is 7 mm thick.
