i have tried and its works very good .........................u must give it a go

even i tried it.. works perfectly....

Hey, will this work on this device? www.trak.lt (sorry for the non-english website)
It is based on the Allwinner A13 chip, same as your device. Also what version of CWM is this and is there any bugs or issues that I should be aware of?

it will work on your device the only bug is that there is no back button but the backup will work perfectly and the version of cwm is 6.0.12

This is my first tablet. I do have one question on this CWM. Let's say if I go flash it with a customized rom and the touchscreen does not work. Since the touchscreen does not work, I have no way to install the novotool.
1. Is CWM still in my tablet after flashing?
2. Is there a way for me to run CWM w/o novotool? Such as pressing particular hardware buttons before it loads ICS.
Sorry for the newbee questions.

first of all u r cwm will not go anywhere if u flash any custom rom and by the there haven't any fully stable custom rom for allwinner a13 is available
2 if the touchscreen is not working u can go to cwm by switch off the tab and then by pressing power button and volume up u can go to cwm
guy my first custom rom is ready and it is very well tested i will upload it by tomorrow ......................

It is necessary to perform recovery increasingly flahs we turn off and turn on the device from one day to another.

I flash with alphadroid and it booting fine. Only one big problem is that touchscreen is not working at all.
I used wired usb mouse (cheap knock off wireless mouse also working great!) and installed novo tool but cannot reboot into recovery because root permission problem. I tried with hardware button to boot into recovery but none work with power+vol.up button nor power+vol.down button. What else can I do? I really LOVE the rom!!!
EDIT: I can get into CWM by going to SETTINGS --> BACKUP & RESET --> Recovery Mode.
I run FIX PERMISSION but when rebooted the root permission denied is still there when I run TBP.

Dude, sorry to post my question here, but I am kinda desperate! My tablet has the exact same specs like yours, but it doesnt recognise the internal SD! So I am looking for a firmware to save the day! Could you tell me how I can find yours? Or could you possibly dump yours and send it to me please?

[RECOVERY] Carliv Touch Recovery 2.7 Alcatel Pop C2 4032A

This is the Carliv Touch Recovery for the Alcatel Pop C2/4032A.
FEATURES​
It is a CWM based recovery and is compatible with it. In this version I used Napstar-xda's full touch module as base. The navigation it is posible by touching the menu item. In long display menu (as choose zip from sdcard) for scroll page down Swipe Right and for scroll page up Swipe Left. For Go Back also Swipe Left.
If the Swipe doesn't work (usually if your phone is multitouch but has only 2 points of touch), use bottom virtual navigation keys or volume buttons Down for Scroll down, Up for Scroll up, and the back button for Go Back.
Click to expand...
Click to collapse
CHANGELOG​
Version 2.7 update (11-dec-2014):
- rebuilt from base (cwm 6.0.3.7) and add improvements on top.
- reintegrated bottom virtual navigation keys, to compensate the non-function of swipe in some phones
- better compressed backups integration - pigz support from cm-11
- new "nvram backup/restore" menu functionality: the nvram partition will be backed up in clockworkmod/backup/.nvram/nvram-xxxxx folder as nvram.img. This will help if you lose IMEI and other communication features. It will work only if you have the nvram partition defined in recovery.fstab. If the nvram partition is damaged (as in flashing an oversized recovery) this will not help you, and you need SPFlashTools to reflash with format your phone official firmware, and after that flash this recovery, boot in recovery and restore nvram.
- the recovery has now an increased stability, many issues are solved
- the content of the backup folder will contain only what an usual clockworkmod backup contain, and that will make it easy to restore backups made with older versions.
- new GUI images, very light (the difference between non-touch modded cwm and this one is only 14 Kb, for 720x1280 resolution)
- some other changes.
Click to expand...
Click to collapse
How to Flash​
Download mobile uncle tools from the playstore and install it
Download the recovery and place it on the sdcard or internal storage
Open mobile uncle tools and allow superSu permission
Go to recovery update and select your recovery.img and flash it
Credits​ @carliv for showing me how to port to mtk devices with custpack partition

Original firmware for an Allwinner H3 TV Box with SV6256P WiFi chip?

I've been searching for days now. I can't seem to find any compatible firmware. The TV Box was marketed to have Android 10.1, 4GB of RAM, 64GB of ROM. False specs tho. The TV Box only ran rooted Android 7.1 and has 16GB of internal storage. Not sure for the RAM, AIDA64 reported 4GB last time I checked. For my use case, I'm fine with that specs. However, after performing a factory reset on it via settings, I can't seem to boot the device anymore. The TV Box is MXQ Pro 4K 5G. It is now stuck on the MBOX boot animation. I've seen firmware online, but not specific to my model. I've seen firmware for the 2.4ghz wifi model only. I've also seen firmware for the 2.4/5ghz model, but for amlogic/rockchip devices and not for Allwinner. I've taken the TV box apart and look for potentially useful information.
Board label: Q44_v4.0_20200602
WiFi: SV6256P TAC2028 13Y11B
RAM: D9PSC (4 chips)
(?): PPT 2016 O PM4 4-11BP
(?): QL 2029
If there's a compatible firmware for this aside from Android, please let me know as well. Thank you!

UPDATE:
Sunvell R69 firmware seems to work but with WiFi, RAM, and storage config issue. WiFi does not work as the firmware is not made specifically for the SV6256P WiFi chip. 1GB of RAM and 8GB of ROM only shows up in AIDA64, which by the way is the default configuration for the Sunvell R69. I've checked the board and it has 4 pcs of D9PSC chips, which I believe are 512MB RAM modules. 2GB of RAM should show up. The board also has the KLMAG1JETD-B041 chip, an 16GB eMMC module for ROM. The device boots rooted Android 7.1.2 just fine. I suppose the issue could be solved by tinkering some system files? I just don't know how just yet.
I've seen a newer version of the Sunvell R69 online, which is the Sunvell H3. It has 2GB of RAM and 16GB of ROM. The WiFi chip isn't still a match however. Despite the WiFi issue, I'm still willing to install the firmware. Better to have 2/16GB than 1/GB only. I can't seem to find any working links for a firmware download however and all my searches so far leads to a dead Google Drive link.
Ive found firmware for MXQ 4K 5G with SV6256P, but for Rockchip only. Is it possible to extract the WiFi drivers from that and load it to my rooted TV box? If so, how could I go about it?

I have same problem... Problem is solved by backup original rom from working box.
Steps that i made is:
-Flash box with this firmware using phoenix suite:
h t t p s:// mega. nz/#!I9oFBISb!8ozfiBuxs7W_pOtr-XnvAzZ_S9xI9GR2Db55AA-03P0
Box boot, but with not working wifi.
-Go and activate developer options and enable usb debugging.Check USB0 device mode enable
-Copy twrp.zip (from archive in link bellow) to flash drive
-Connect phoenix suite to box and press recovery.Box will boot into recovery mode
-Press install update from external and choose twrp.zip (executable only) DO NOT TRY to install, just run it!
-Make full backup of "no-wifi" rom (check all boxes) and save it to external flash drive
-When is done, disconnect flash drive from box and connect to pc. Replace only files ( from backup in link bellow ) to folder in flash drive. DO NOT rename folder!
-Boot box to "no-wifi" rom and connect to phoenix suite, press recovery again.
- From stock recovery load twrp.zip again, point where backup is, mark again all boxes, and choose restore.
- Wait to finish and press reboot when is done. Box will boot to stock firmware with working wi-fi ...
Link to backup with all needed files:
